    Most studies on the quality of life (Qol) of patients with schizophrenia deal with objective living conditions and how they are perceived by hospitalized patients. The few studies that compare Qol for patients treated in part time services with the Qol of ambulatory patients do not show any significant difference in terms of subjective Qol. Some stu-dies evaluate the influence of psychopathology and needs (or expectations) on the subjective Qol in these groups of patients. Available data indicate that the general well-being is influenced by psychopathology (positive, negative or depressive symptoms) and unmet needs in ambulatory patients. They also show that subjective Qol in certain life domains (social relations, family relations, leisure, health, law and security) is influenced by negative symptoms, anxiety and depression in patients treated in part-time services. The aim of this study is to compare the objective and subjective Qol of patients with schizophrenia treated in part time services (day hospital and day care center) to the Qol of out-patients treated on a purely ambulatory basis (out patient clinic). We studied the Qol of 2 groups of 30 patients with schizophrenia (ICD 10 criteria) treated in various centers. The first group was made of ambulatory patients, the second one was constituted of patients treated in a day hospital or a day care center. Patients were matched for age, duration of illness, number of hospitalizations. The instruments used for rating were the following: Clinical Global Impression (CGI), Global Assessment of Functioning (GAF), Positive And Negative Symptoms Scale (PANSS), Drug Attitude Inventory (DAI-10). The Qol was measured with a french version of the Lancashire Quality Of Life Profile (LQOLP) (Salomé, Germain, Petitjean, Demant and Boyer, 2000). This instrument measures the objective Qol as well as the subjective Qol. It does possess satisfying psychometric properties and offers the possibility to establish Qol profiles. All

    Cancer patients frequently experience malnutrition. Cancer and cancer therapy effects nutritional status through alterations in the metabolic system and reduction in food intake. In the present study, fifty seven cancer patients were selected as subjects from the oncology ward of Cachar Cancer Hospital and Research Centre, Silchar, India. Evaluation of nutritional status of cancer patients during treatment was carried out by scored Patient-Generated Subjective Global Assessment (PG-SGA). The findings of PG-SGA showed that 15.8% (9) were well nourished, 31.6% (18) were moderately or suspected of being malnourished and 52.6% (30) were severely malnourished. The prevalence of malnutrition was highest in lip/oral (33.33%) cancer patients. The study showed that the prevalence of malnutrition (84.2%) was high in cancer patients during treatment.

    Personality and social support (SS) influence risk for depression and modify its outcome through multiple pathways. The impact of personality dimensions neuroticism and extraversion on SS among patients with major depressive disorder (MDD) has been little studied. In the Vantaa Depression Study, we assessed neuroticism and extraversion with the Eysenck Personality Inventory, objective SS with the Interview Measure of Social Relationships, and subjective SS with the Perceived Social Support Scale-Revised at baseline, at 6 and 18 months among 193 major depressive disorder patients diagnosed according to the fourth edition of Diagnostic and Statistical Manual of Mental Disorders (DMS-IV). At all time-points, low neuroticism and high extraversion associated significantly with between-subject differences in levels of objective and subjective SS. Lower neuroticism (beta = 0.213, p = 0.003) and higher extraversion (beta = 0.159, p = 0.038) predicted greater within-subject change of subjective, but not objective SS. Thus, neuroticism and extraversion associated with the size of objective and subjective SS and predicted change of subjective SS. Modification of subjective SS, particularly, may indirectly influence future vulnerability to depression.

    Full Text Available (1 Background: Literature suggests that high levels of dopamine are associated with creative thoughts. Tourette Syndrome (TS patients have high dopamine levels, while Parkinson’s Disease (PD subjects have low dopamine levels. Consequently, TS individuals are supposed to have a major and PD patients less creative output. Moreover, dopamine medications may alter the level of creativity, and therefore Quality of Life, in both pathologies. (2 Methods: The aim of the study was to verify the hypothesis of TS patients having higher creative scores than PD patients. The assessment consisted of the administration of the Creative Thinking ASK Test. There were 54 participants—36 males and 18 females—i.e., 27 TS patients and 27 PD subjects. Age of the sample was 35 to 57 years old, high school certificate was required. (3 Results: TS sample (103.11 ASK average score was more creative than PD sample (94.11 ASK average score. (4 Conclusions: The results supported the aforementioned hypothesis: TS sample resulted in having higher creative scores than PD sample. Dopamine and other neurotransmitters of TS and PS appear to affect subject’s creativity. Further studies with creative assessments in TS and PD patients are needed to support the preliminary results of our study.

    Sleep disturbance is common in chronic post-traumatic stress disorder (PTSD). However, prior work has demonstrated that there are inconsistencies between subjective and objective assessments of sleep disturbance in PTSD. Therefore, we investigated whether subjective or objective sleep assessment has greater clinical utility to differentiate PTSD patients from healthy subjects. Further, we evaluated whether the combination of subjective and objective methods improves the accuracy of classification into patient versus healthy groups, which has important diagnostic implications. We recruited 32 chronic war-induced PTSD patients and 32 age- and gender-matched healthy subjects to participate in this study. Subjective (i.e. from three self-reported sleep questionnaires) and objective sleep-related data (i.e. from actigraphy scores) were collected from each participant. Subjective, objective, and combined (subjective and objective) sleep data were then analyzed using support vector machine classification. The classification accuracy, sensitivity, and specificity for subjective variables were 89.2%, 89.3%, and 89%, respectively. The classification accuracy, sensitivity, and specificity for objective variables were 65%, 62.3%, and 67.8%, respectively. The classification accuracy, sensitivity, and specificity for the aggregate variables (combination of subjective and objective variables) were 91.6%, 93.0%, and 90.3%, respectively. Our findings indicate that classification accuracy using subjective measurements is superior to objective measurements and the combination of both assessments appears to improve the classification accuracy for differentiating PTSD patients from healthy individuals.

    The purpose of this study is to present the results of a systematic review of published research that focuses on psychological aspects of malignant mesothelioma patients and asbestos-exposed people. Our research includes primary studies published between 1980 and 2016, using information from the Cochrane Library, the Psychology Behavioral Sciences Collection, PsychINFO, PubMed, PubGet, PubPsych, and Scopus, in compliance with PRISMA guidelines. We identified 12 papers that investigated the psychological distress and care needs of mesothelioma patients, and nine papers for asbestos-exposed subjects. This paper highlights the paucity of studies on the psychological distress and care needs of mesothelioma patients and asbestos-exposed subjects. It confirms that malignant mesothelioma is associated with the physical, emotional, and social functioning of patients, while also suggesting that the risk of developing asbestos-related diseases among asbestos-exposed subjects is associated with high levels of psychological distress, despair, and mental health difficulties. © 2018 Wiley Periodicals, Inc.

    Patients with narcolepsy often complain about attention deficits in everyday situations. In comparison with these subjective complaints, deficits in objective testing are subtler. The present study assessed the relationships between subjective complaints, objectively measured cognitive performance, disease-related variables, and mood. A total of 51 patients with narcolepsy and 35 healthy controls responded to questionnaires regarding subjectively perceived attention deficits, sleepiness, anxiety and depression. Moreover, they performed an extensive neuropsychological assessment tapping into attention, executive functions, and memory. Patients rated their level of attention in everyday situations to be relatively poor. In an objective assessment of cognitive functioning, they showed only slight attention and executive function deficits. The subjective ratings of attention deficits significantly correlated with ratings of momentary sleepiness, anxiety, and depression, but not with objectively measured cognitive performance. Momentary sleepiness and depression predicted almost 39% of the variance in the ratings of subjectively perceived attention deficits. The present study showed that sleepiness and depression, more than objective cognitive deficits, might play a role in the subjectively perceived attention deficits of patients with narcolepsy. The results suggested that when counselling and treating patients with narcolepsy, clinicians should pay attention to potential depression because subjective cognitive complaints may not relate to objective cognitive impairments.

    The objective of our study was to evaluate whether there is injury to the transverse ligament of the atlas in patients with acute whiplash. Ninety patients with an acute (transverse ligament was measured on midsagittal T1 volumetric interpolated breath-hold examination (VIBE) images and transverse reformatted VIBE images. The signal intensity of the transverse ligament was measured on transverse STIR images and on transverse reformatted T1 VIBE images before and after IV administration of gadoterate. Contrast between the transverse ligament and CSF and alterations of contrast after gadoterate injection were calculated. Patients had a minimally thicker transverse ligament (posttraumatic swelling) than control subjects, and the difference in thickness was significant in men only (p = 0.03). In patients, a significant signal alteration of the transverse ligament (p = 0.03) was seen on STIR (posttraumatic edema) and native VIBE sequences. The contrast between the transverse ligament and the CSF on VIBE images was significantly (p = 0.005) lower in patients than in control subjects. With the application of a contrast agent, the contrast difference between the transverse ligament and CSF in patients and control subjects was less pronounced (p = 0.038). There was no abnormal uptake of contrast agent by the transverse ligament or CSF. The results of our study indicate possible involvement of the transverse ligament in whiplash injury. Although MRI may be helpful to study injury-related changes of anatomic structures in cohorts, it is not suited for individual diagnosis because the alterations are too small.

    Patients with end-stage renal disease treated with chronic hemodialysis (HD) are reported to have low levels of marine n-3 polyunsaturated fatty acids (PUFA) in plasma and cell membranes compared with healthy subjects. The aim of this study was to investigate whether n-3 PUFA levels in plasma and cells are lower in HD patients as compared with subjects without kidney disease. A comparative study was carried out. This study was carried out at the Departments of Nephrology and Cardiology, Aalborg Hospital, Aarhus University Hospital, Denmark. This study consisted of 2 study populations comprising HD patients and 5 study populations comprising subjects without kidney disease. The fatty acid distribution in plasma phospholipids and platelet phospholipids was measured using gas chromatography. Eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and arachidonic acid (AA) levels in plasma or serum phospholipids and platelet phospholipids in HD patients were compared with n-3 PUFA levels in subjects without kidney disease. EPA and DHA were lower and AA/EPA was higher in plasma/serum phospholipids in HD patients than in subjects without kidney disease. Similarly, higher AA and AA/EPA and lower EPA and DHA levels were found in platelet phospholipids of HD patients. Adjustment for gender, age, and habitual intake of fish and fish oil supplements did not change these results. HD patients have lower n-3 PUFA levels in plasma and cells compared with subjects without kidney disease. Copyright © 2011 National Kidney Foundation, Inc. Published by Elsevier Inc.

    Full Text Available Background and Objective This study aimed to investigate objective and subjective continuous positive airway pressure (CPAP compliance in patients with obstructive sleep apnea syndrome (OSAS. Moreover, we evaluated the factors and benefits associated with good CPAP compliance. Methods Subjects were 153 OSAS patients who underwent polysomnography for CPAP titration. Subjective compliance was defined as reported CPAP use of at least 4 hours a day for five or more days per week, and objective compliance was defined as CPAP use of at least 4 hours a day for more than 70% of the time recorded in the CPAP machine. Results The subjective and objective compliance rates were 34.0% and 20.7%, respectively. Subjectively compliant patients had lower minimum O2 saturation and higher % of time with O2 saturation lower than 90% than did patients declining CPAP treatment. Objectively compliant patients had lower insomnia and depression score and lower minimum O2 saturation than did patients declining CPAP treatment. Daytime sleepiness and subjective sleep quality improved to the same extent in both objectively and subjectively compliant patients. Conclusions Lower insomnia score and more severe OSA correlate with good CPAP compliance. CPAP effect was comparable between subjectively and objectively compliant patients.

    In Germany, utilisation of ambulatory healthcare services is high compared with other countries: While a study based on the process data of German statutory health insurances showed an average of 17.1 physician-patient-contacts per year, the comparable figure for Norway is about five. The usual models of healthcare utilisation, such as Rosenstock's Health Belief Model and Andersen's Behavioural Model, cannot explain these differences adequately. Organisational factors of the healthcare system, such as gatekeeping, do not explain the magnitude of the differences. Our hypothesis is that patients' subjective concepts about primary healthcare utilisation play a major role in explaining different healthcare utilisation behaviour in different countries. Hence, the aim of this study is to explore these subjective concepts comparatively, between Germany and Norway. With that aim in mind, we chose a comparative qualitative study design. In Norway and Germany, we are going to interview 20 patients each with qualitative episodic interviews. In addition, we are going to conduct participant observation in four German and four Norwegian primary care practices. The data will be analysed by thematic coding. Using selected categories, we are going to conduct comparative case and group analyses. The study adheres to the Declaration of Helsinki. All interviewees will sign informed consent forms and all patients will be observed during consultation. Strict rules for data security will apply. Developed theory and policy implications are going to be disseminated by a workshop, presentations for experts and laypersons and publications.

    As part of a Nordic multi-centre study investigating the life and care situation of community samples of schizophrenic patients the aim of the present part of the study was to examine the relationship between global subjective quality of life and objective life conditions, clinical characteristics including psychopathology and number of needs for care, subjective factors such as satisfaction with different life domains, social network, and self-esteem. A sample of 418 persons with schizophrenia from 10 sites was used. The results of a final multiple regression analysis, explaining 52.3% of the variance, showed that five subjective factors were significantly associated with global subjective quality of life, together with one objective indicator, to have a close friend. No clinical characteristics were associated with global subjective quality of life. The largest part of the variance was explained by satisfaction with health, 36.3% of the variance, and self-esteem, 7.3% of the variance. It is concluded that the actual relationship between objective life conditions and subjectively experienced quality of life still remains unclear. Furthermore, it seems obvious that personality related factors such as self-esteem, mastery and sense of autonomy also play a role in the appraisal of subjective quality of life, which implies that factors like these are important to consider in clinical and social interventions for patients with schizophrenia in order to improve quality of life for these persons.

    Full Text Available ABSTRACT Objective To determine the association of a scored patient-generated Subjective Global Assessment with mortality and length of hospital stay in cancer patients. Methods Cross-sectional study carried out between July and September 2014 using secondary data collection using data from 366 medical records of patients admitted to a hospital recognized as a cancer center of excellence. The present study included patients with hospital stay over than or equal three days and minimum age of 20 years. The patient-generated Subjective Global Assessment scores were calculated and compared with the patients’ clinical and anthropometric characteristics and outcomes (death and long length of stay in hospital. Results Of the 366 patients evaluated, 36.0% were malnourished. The presence of malnutrition, according to the scored patient-generated Subjective Global Assessment, was statistically associated with the presence of metastasis (52.4%. On the other hand, malnutrition, according to the body mass index in adults (55.8% and in older elderly patients (54.2%, was associated with death (55.0%. The adjusted logistic regression model showed that the following factors were associated with prolonged hospitalization: early nutritional screening, presence of severe malnutrition, radiotherapy and chemotherapy, and surgical procedures. As for mortality, the associated factors were: male reproductive system tumor, presence of metastasis, clinical treatment, prolonged hospitalization, and the presence of some degree of malnutrition. Conclusion The patient-generated Subjective Global Assessment score is an important risk marker of prolonged hospitalization and mortality rates. It is a useful tool capable of circumventing significant biases in the nutritional evaluation of cancer patients.

Patients were interviewed about their smoking status. Blood samples were taken from all the patients prior to surgery and for an additional 6 weeks following surgery. Serum levels of cotinine were measured, and coherence between subjective smoking status and objective cotinine analysis was evaluated.  Results: Between March 2012 and August 2014, we enrolled 136 patients. Six of the 26 “previous smokers” (23% and four of the 65 “nonsmokers” (6% had serum cotinine above cutoff levels. In self-labeled smokers, serum cotinine levels averaged at 2,367.4±14,885.9 ng/mL (with a median of 100 ng/mL, whereas in previous smokers the levels averaged at 4,270±19,619.4 ng/mL (with a median of 0 ng/mL and in the nonsmokers group the levels averaged at 12±53.9 ng/mL (with a median of 0.03 ng/mL. Overall, the subjective smoking status matched serum cotinine testing in 88% of the cases. Sensitivity was 79.6% and specificity was 93.1%. Ninety-one percent of the patients with preoperative positive serum values were still positive at follow-up.  Conclusion: In this study, we could show that subjective smoking status in orthopedic patients is predominantly reliable as validated by objective cotinine measurements; however, patients who declare themselves as “previous smokers” are at elevated risk

    Despite the vast amount of scientific literature available on electroconvulsive therapy (ECT), there is little qualitative focus upon the patients' subjective experience of this procedure. Using an exploratory descriptive methodology, this study aims to provide a more unique insight into what certain patients actually think of ECT. Semistructured interviews were conducted to explore eight patients' opinions and experiences of ECT. Interviews were subjected to analysis by a five-step framework approach that identified prominent themes in relation to five broad questions and in conjunction with issues raised by the subjects themselves. Eleven major themes were identified. Four of these were chosen for discussion, not only as the most prevalent themes (in terms of how frequently they were mentioned by the subjects), but also as the most striking (in regards to the intensity of emotions evoked, or their influence on their perception of ECT as a future treatment option). The four themes are fear of ECT, attribution of cognitive decline and memory loss to ECT, positive ECT experiences, and patients' suggestions. Using such a qualitative approach, the depth of the information obtained has revealed new perspectives on how patients perceive the experience of ECT. Fears reported by patients present an opportunity to address specific areas of the procedure that generate the most angst. These were closely associated with recommendations that many patients proposed throughout the interviews. Patients' perceptions of the cognitive effects of ECT do not necessarily correspond with those commonly reported in the literature on ECT. Positive experiences with ECT were more complex than simply its efficacy. There is a need for future research in order to explore and address patients' experiences of ECT.

    Oral anticoagulation (OAC) is state-of-the-art therapy for atrial fibrillation (AF), the most common arrhythmia worldwide. However, little is known about the perception of patients with AF and how it correlates with risk scores used by their physicians. Therefore, we correlated patients' estimates of their own stroke and bleeding risk with the objectively predicted individual risk using CHA 2 DS 2 -VASc and HAS-BLED scores. Cross-sectional prevalence study using convenience sampling and telephone follow-up. Eight hospital departments and one general practitioner in Austria. Patients' perception of stroke and bleeding risk was opposed to commonly used risk scoring. Patients with newly diagnosed AF and indication for anticoagulation. Comparison of subjective risk perception with CHA 2 DS 2 -VASc and HAS-BLED scores showing possible discrepancies between subjective and objective risk estimation. Patients' judgement of their own knowledge on AF and education were also correlated with accuracy of subjective risk appraisal. Ninety-one patients (age 73±11 years, 45% female) were included in this study. Subjective stroke and bleeding risk estimation did not correlate with risk scores (ρ=0.08 and ρ=0.17). The majority of patients (57%) underestimated the individual stroke risk. Patients feared stroke more than bleeding (67% vs 10%). There was no relationship between accurate perception of stroke and bleeding risks and education level. However, we found a correlation between the patients' judgement of their own knowledge of AF and correct assessment of individual stroke risk (ρ=0.24, p=0.02). During follow-up, patients experienced the following events: death (n=5), stroke (n=2), bleeding (n=1). OAC discontinuation rate despite indication was 3%. In this cross-sectional analysis of OAC-naive patients with AF, we found major differences between patients' perceptions and physicians' assessments of risks and benefits of OAC.

    Full Text Available Background: Subjective cognitive impairments are frequent, but poorly understood in patients with chronic fatigue. We hypothesized that maladaptive metacognitive beliefs at baseline were associated with baseline subjective cognitive impairments, that they predict subjective cognitive impairments at treatment termination, and that a reduction in maladaptive metacognitive beliefs was associated with less subjective cognitive impairments at treatment termination, independent of changes in fatigue, pain, insomnia, depression, and anxiety.Methods: In this non-controlled study, patients (n=137 on sick leave due to chronic fatigue received a 3.5-week inpatient RTW rehabilitation program. Of these patients 69 (50.4 % was referred with a ICPC-2 diagnosis of chronic fatigue. Patients completed questionnaires about metacognitive beliefs, somatic complaints, psychological complaints, and cognitive impairments before and after treatment. To test the hypotheses we performed paired t tests of change, as well as seven hierarchical linear regressions.Results: Results showed that baseline maladaptive metacognitive beliefs were significantly associated with subjective cognitive impairments at baseline, controlling for symptoms. Score on baseline metacognitive beliefs did not predict impairments post-treatment. Testing specific maladaptive beliefs, pre-treatment scores on cognitive confidence were associated with subjective cognitive impairments both pre and post-treatment, controlling for symptoms. Post-treatment metacognitive beliefs and post-treatment cognitive confidence were associated with post-treatment subjective cognitive impairments, controlling for pre-treatment impairments and pre-treatment metacognitive beliefs, as well as pre and post scores on symptom measures. Conclusion: This study reports associations between maladaptive metacognitive beliefs and subjective cognitive impairments in patients with chronic fatigue. Targeting metacognitive beliefs

    To evaluate the nutritional status of non-critically ill digestive surgery patients at the moment of parenteral nutrition initiation using three different nutritional test tools and to study their correlation. To study the association between the tests and the clinical and laboratory parameters used in the follow-up of PN treatment. Prospective study over 4 months. Anthropometric and clinical variables were recorded. Results of Subjective Global Assessment; Patient-Generated Subjective Global Assessment; and Nutritional Risk Screening 2002 were compared applying kappa test. Relationship between the clinical and laboratory parameters with Subjective Global Assessment was studied by multinominal regression and with the other two tests by multiple linear regression models. Age and sex were included as adjustment variables. Malnutrition in 45 studied patients varied from 51% to 57%. Subjective Global Assessment correlated well with Patient-Generated Subjective Global Assessment and Nutritional Risk Screening 2002 (κ = 0531 p = 0.000). The test with the greatest correlation with the clinical and analytical variables was the Nutritional Risk Screening 2002. Worse nutritional state in this test was associated with worse results in albumin (B = -0.087; CI = -0.169/-0.005], prealbumin (B = -0.005; CI = [-0.011/-0.001]), C-reactive protein (B = 0.006;CI = [0.001/ 0.011]) and leukocytes (B = 0.134; CI = [0.031/0.237]) at the en of parenteral nutrition treatment. Half of the digestive surgery patients were at malnutritional risk at the moment of initiating parenteral nutrition. Nutritional Risk Screening 2002 was the test with best association with the parameters used in the clinical follow-up of parenteral nutrition treated patients. Copyright AULA MEDICA EDICIONES 2014.

    In order to investigate the clinical characteristics of cerebral arteriosclerosis in diabetic subjects, brain MRI studies were conducted in diabetic patients and healthy subjects. The subjects were 93 diabetic patients without symptoms and signs of cerebral infarction (49 males and 44 females) with a mean age of 59 years and 73 healthy subjects (43 males and 30 females) with a mean age of 57 years. The MRI studies were performed on a General Electric 1.5-T signa system. The spin-echo technique (T2-weighted image) was used with a pulse repetition time (TR) of 2,500 msec and echo time (TE) of 80 msec. The quantitative evaluation of cerebral infarction was assessed using personal computer and image-scanner. By MRI, the incidence of cerebral infarction in diabetic patients was significantly higher than that in healthy subjects (30.1% vs. 13.7%, respectively, p<0.05). The mean age of the diabetic patients with cerebral infarctions was higher than that of those without cerebral infarctions. Hypertension and diabetic nephropathy were present more frequently in the subjects with cerebral infarctions. These data suggest that it is important to delay the onset and slow the progression of cerebral infarction in diabetic patients by strict blood glucose control and management of blood pressure.

    This study aimed to evaluate the nutritional status of patients with cancer in palliative care and to examine the interrelationship between objective and subjective nutritional assessment measures. Patients' nutritional status in a palliative care unit of a Malaysian government hospital and a hospice facility were assessed using anthropometric measurements, weight loss at 1/6 months, and the scored patient-generated subjective global assessment (PG-SGA). Moderate-to-severe malnutrition was observed in a range from 31% to 69% using both measurements. Common nutritional impact symptoms were pain, xerostomia, and anorexia. Patient-generated subjective global assessment scores were significantly correlated with anthropometric measurements (P nutritional status assessment of patients with cancer in palliative care.

    The purpose of these studies was to develop a radiologic method for assessing gastric emptying of an indigestible solid in humans and to apply this technique to the evaluation of patients with diabetes mellitus. Thirty healthy subjects ingested 10 solid radiopaque markers (small pieces of nasogastric tubing) together with a standard meal (donuts and 7-Up). Radiographs of the upper abdomen were obtained hourly for up to 6 h until all markers had emptied from the stomach. In some experiments, 99mTc-labeled scrambled eggs were added to the meal so that emptying of this digestible solid, assessed by scintigraphy, could be compared with emptying of liquids and solid radiopaque markers. In healthy subjects, the digestible solid emptied more slowly than the liquid (t 1/2 . 154 +/- 11 min vs. 30 +/- 3 min, p less than 0.001), but emptying of digestible solid was significantly faster than the emptying of the indigestible solid radiopaque markers. In diabetics, emptying rates for the digestible solid and liquid were close to normal (t 1/2 . 178 +/- 5 min and 40 +/- 3 min, respectively), whereas indigestible solid markers were retained in the stomach 6 h after the meal in 50% of the patients. Radiopaque markers proved to be a simple method for measuring gastric emptying of indigestible solids in humans. Using this technique, patients with insulin-dependent diabetes mellitus had a high incidence of abnormally slow gastric emptying of indigestible solids; the method may be a more sensitive indicator of gastric motor dysfunction than radionuclide scintigraphy

    Full Text Available Abstract Background This study tested the homeostatic model of subjective quality of life in a group of 47 short stay patients as they progressed through the stages of hospitalization for surgery. Method Participants completed a questionnaire measuring subjective quality of life, positive and negative affect, self-esteem, optimism and cognitive flexibility, the day prior to admission (T1, two days post-operation (T2 and one week after discharge (T3. Neuroticism and Extroversion were measured at Time 1. Results All variables remained stable across the three times, apart from positive affect, which dropped significantly post-operation but returned to its previous level post discharge. Conclusion Although the homeostatic model of subjective quality of life was supported at Time 1, the analyses raise doubts about the stability of personality. This finding is consistent with recent discussions of personality.

    Full Text Available Abstract Background Being severely overweight is a distinctive clinical feature of Prader-Willi Syndrome (PWS. PWS is a complex multisystem disorder, representing the most common form of genetic obesity. The aim of this study was the analysis of the gait pattern of adult subjects with PWS by using three-Dimensional Gait Analysis. The results were compared with those obtained in a group of obese patients and in a group of healthy subjects. Methods Cross-sectional, comparative study: 19 patients with PWS (11 males and 8 females, age: 18–40 years, BMI: 29.3–50.3 kg/m2; 14 obese matched patients (5 males and 9 females, age: 18–40 years, BMI: 34.3–45.2 kg/m2; 20 healthy subjects (10 males and 10 females, age: 21–41 years, BMI: 19.3–25.4 kg/m2. Kinematic and kinetic parameters during walking were assessed by an optoelectronic system and two force platforms. Results PWS adult patients walked slower, had a shorter stride length, a lower cadence and a longer stance phase compared with both matched obese, and healthy subjects. Obese matched patients showed spatio-temporal parameters significantly different from healthy subjects. Furthermore, Range Of Motion (ROM at knee and ankle, and plantaflexor activity of PWS patients were significantly different between obese and healthy subjects. Obese subjects revealed kinematic and kinetic data similar to healthy subjects. Conclusion PWS subjects had a gait pattern significantly different from obese patients. Despite that, both groups had a similar BMI. We suggest that PWS gait abnormalities may be related to abnormalities in the development of motor skills in childhood, due to precocious obesity. A tailored rehabilitation program in early childhood of PWS patients could prevent gait pattern changes.

    To investigate cerebral regions concerning a memory function and presence of memory lateralization, activated areas and the difference between the right and left hemisphere in functional magnetic resonance imaging (f-MRI) during verbal and visual memory tasks were examined in normal subjects and, as its clinical application, in patients with partial epilepsies. Subjects were 39 normal adult subjects and 10 adult patients. Of the 39 normal subjects, 30 were right-handed and 9 were left-handed. Further, of the 10 patients, 9 were right-handed and one was left-handed, and 7, 2 and 1 had temporal lobe, frontal lobe and undetermined partial epilepsies, respectively. Following the three type of memory task were designed; verbal memory tasks consisting of covert and overt recall tests of 10 words given auditory and visual memory task of covert recall tasks of 6 figures given visually. Activated cerebral areas were imaged with f-MRI using 1.5 tesla Magnetom Vision taken repeatedly during these tasks and neutral condition. Most of the 30 right-handed normal subjects showed activated areas over the left hemisphere specifically on the anterior cingulate, superior, middle and inferior frontal gyri during the verbal memory tasks of covert recall tests. Left hemisphere dominant activated areas in the precentral gyri were added during the verbal memory tasks of overt recall tests. On the other hand, 4 of the 9 left-handed normal subjects showed the left side-dominantly activated areas in the above-mentioned regions during the verbal memory tasks of covert and overt tests, in common with the right-handed subjects. However, 3 of the 9 left-handed normal subjects had right hemisphere dominant activation during the verbal memory tasks, while none of the 30 right-handed normal subjects showed such right side-dominancy. Further, the bilateral occipital lobes were activated during visual memory tasks. The reproducibility in this activation during these verbal and visual memory tasks

    BAG3 is a member of human BAG (Bcl-2-associated athanogene) proteins and plays a role in apoptosis, cell adhesion, cytoskeleton remodeling, and autophagy. The aim of this study was to evaluate BAG3 levels in healthy subjects, hypertensive patients, and hypertensive diabetic patients. We enrolled 209 Caucasian adults, of both sex, 18-75 years of age, 77 were healthy controls, 62 were affected by hypertension, and 70 were affected by hypertension and type 2 diabetes. All patients underwent an assessment that included medical history, physical examination, vital signs, a 12-lead electrocardiogram, measurements of systolic (SBP), and diastolic blood pressure (DBP), heart rate (HR), fasting plasma glucose (FPG), glycated hemoglobin (HbA 1c ), triglycerides (TG), transaminases, high sensitivity C-reactive protein (Hs-CRP), and BAG3. We observed higher blood pressure values in hypertensive, and hypertensive diabetic patients compared to controls. As expected, FPG and HbA 1c were higher in diabetic hypertensive patients, compared to the other two groups. No Tg levels differences were recorded among the three groups. Hs-CRP was higher in diabetic hypertensive patients compared to healthy subjects. Finally, BAG3 levels were higher in hypertensives, and hypertensive diabetic patients compared to controls. We observed higher levels of BAG3 in hypertensive patients compared to healthy controls, and even higher levels in hypertensive diabetic patients compared to healthy subjects. This paper could be the first of a long way to identify potential involvement of deregulated BAG3 levels in cardiometabolic diseases. © 2017 Wiley Periodicals, Inc.

    Radioactive tracer techniques using 131 I- and 125 I-insulin have been applied to study insulin metabolism. A simple method to label human insulin with 123 I to a high specific activity is described. We have used this radiotracer to study insulin kinetics in vivo in normal subjects and in two groups of diabetic patients. The rate of decline in plasma radioactivity was shown to be significantly reduced in patients with diabetes. There were no significant differences in the time -activity profiles of liver and kidneys between the groups studied. This technique may provide insight into the mechanism of some forms of insulin resistance. (author)

    Full text: In this work the doses to critical organs in pediatric patient subjected to studies of multi cutting skull tomography were determined. The study included patient smaller than 16. The used tomograph was a Siemens Somaton 16 plus multi cutting. The dosimetry one carries out with thermoluminescent dosemeters of LiF:Mg,Cu,P +Ptfe of national production. This dosemeters type was used due to it characteristics, such as low fading, equivalence with the tissue, easy handling and reading and independence of it answer with the radiation energy. The value of the absorbed doses in organs in the simple study results half of the obtained value in the contrasted study that which indicates that the CTDI vol is proportional to the dose to organ. In the case of the skull three-dimensional reconstruction tomography the CTDI vol was practically the same one that for simple tomography was practically; however, the doses to organs differed significantly. When comparing the TDI vol value of the three-dimensional reconstruction tomography with that of the contrasted tomography the obtained reason it was 1:2; however, the doses to organ didn't show the same relationship and the absorbed dose in the case of the thyroid gland was even bigger in the study of three-dimensional reconstruction. The value of the CTDI vol is a good indicator of the exposure factors selected for the tomographic exploration and it is useful for the determination of the effective dose, but it doesn't indicate the absorbed dose to organ.

    Chronic nonspecific low back pain is accompanied by high rates of comorbid mental and physical conditions. The aims of this study were to investigate if patients with specific back pain, that is, sciatica caused by lumbar herniation, report higher rates of subjective health complaints (SHCs) than the general population and if there is an association between change in sciatica symptoms and change in SHCs over a 12-month period. A multicenter cohort study of 466 sciatica patients was conducted with follow-up at 3 months and 1 year. Comorbid SHCs were measured by 27 items of the SHC inventory. Odds ratios (ORs) for each SHC were calculated with comparison to a general population sample (n=928) by logistic regression. The SHC number was calculated by summing all complaints present. At baseline, the ORs for reporting SHCs for the sciatica patients were significantly elevated in 15 of the 27 items with a mean (S.D.) SHC number of 7.5 (4.4), compared to 5.2 (4.4) in the general population (Psciatica, the SHC number was reduced to normal levels. Among those with persisting or worsening sciatica, the number increased to a level almost double that of the general population. Compared to the general population, the prevalence of subjective health complaints in sciatica is increased. During follow-up, the number of health complaints increased in patients with persisting or worsening sciatica. Copyright © 2010 Elsevier Inc. All rights reserved.

We followed up 274 patients (151 men; mean age, 71 ± 7.4 years for 3 years. A multivariable logistic regression model was used to assess the predictive factors for subjective symptom improvement with nonsurgical treatment.In 30% of patients, conservative treatment led to a subjective improvement in the symptoms; in 70% of patients, the symptoms remained unchanged, worsened, or required surgical treatment. The multivariable analysis of predictive factors for subjective improvement with nonsurgical treatment showed that the absence of cauda equina symptoms (only radicular symptoms had an odds ratio (OR of 3.31 (95% confidence interval [CI]: 1.50-7.31; absence of degenerative spondylolisthesis/scoliosis had an OR of 2.53 (95% CI: 1.13-5.65; <1-year duration of illness had an OR of 3.81 (95% CI: 1.46-9.98; and hypertension had an OR of 2.09 (95% CI: 0.92-4.78.The predictive factors for subjective symptom improvement with nonsurgical treatment in LSS patients were the presence of only radicular symptoms, absence of degenerative spondylolisthesis/scoliosis, and an illness duration of <1 year.

    The purpose of these studies was to develop a radiologic method for assessing gastric emptying of an indigestible solid in humans and to apply this technique to the evaluation of patients with diabetes mellitus. Thirty healthy subjects ingested 10 solid radiopaque markers (small pieces of nasogastric tubing) together with a standard meal (donuts and 7-Up). Radiographs of the upper abdomen were obtained hourly for up to 6 h until all markers had emptied from the stomach. Although most of the liquid component of the meal, labeled with 111In, emptied during the first hour (as assessed simultaneously by radionuclide scintigraphy), few radiopaque markers emptied from the stomach during the first 2 h after the meal. Most markers emptied during the fourth postprandial hour, and all 10 markers had emptied by 6 h in 45 of 46 experiments. In contrast, not all of the solid radiopaque markers emptied from the stomach by 6 h in 16 of 26 experiments in patients with diabetes mellitus (p less than 0.001 vs. healthy controls). In some experiments, 99mTc-labeled scrambled eggs were added to the meal so that emptying of this digestible solid, assessed by scintigraphy, could be compared with emptying of liquids and solid radiopaque markers. In healthy subjects, the digestible solid emptied more slowly than the liquid (t 1/2 = 154 +/- 11 min vs. 30 +/- 3 min, p less than 0.001), but emptying of digestible solid was significantly faster than the emptying of the indigestible solid radiopaque markers. In diabetics, emptying rates for the digestible solid and liquid were close to normal (t 1/2 = 178 +/- 5 min and 40 +/- 3 min, respectively), whereas indigestible solid markers were retained in the stomach 6 h after the meal in 50% of the patients. Radiopaque markers proved to be a simple method for measuring gastric emptying of indigestible solids in humans. Using this technique, patients with insulin-dependent diabetes mellitus had a high incidence of abnormally slow gastric emptying of

    Lid hygiene is a commonly prescribed first-line therapy in patients with lid margin disease, yet compliance with therapy is not well characterized. The goals of this study were to assess patient compliance with lid hygiene and evaluate which factors predict a favorable symptomatic response to treatment. This was a cross-sectional study of patients seen in the Miami Veterans Affairs eye clinic between August and December 2014. An evaluation was performed to assess dry eye symptoms and lid margin signs. All patients were then instructed to perform warm compresses and lid scrubs. A follow-up phone survey assessed compliance and subjective therapeutic response 6 weeks later. Two hundred seven of 211 (98%) patients (94% male, 60% white) completed the survey. Of the 207 patients, 188 (91%) completed the follow-up survey. Compliance with therapy was reported in 104 patients (55%); 66 reported complete improvement, 30 partial improvement, and 8 no improvement in symptoms. Patients who self-reported dry eye symptoms at first visit (n=86, 74%) were more likely to be compliant with lid hygiene than those who did not report symptoms (n=18, 25%) (Phygiene was longer time of self-reported dry eye symptoms. None of the other signs studied, including the presence of skin rosacea and lid margin telangiectasia, were associated with a differential response to lid hygiene. Patients with dry eye symptoms were moderately compliant with lid hygiene, and patients who performed the routine noted improvement in symptoms.

    Full Text Available Abstract Background There are limited findings about dietary patterns and food preferences among patients suffering from schizophrenia. The main objective of this study was therefore to compare the nutritional pattern of schizophrenia patients with that of matched healthy subjects. Methods The dietary pattern of 30 hospitalized 16–67 years old schizophrenic patients (11 female was compared with that of 30 healthy age and sex matched individuals as control group. Subjects' anthropometric measurements including weight, height and body mass index (BMI, semi-quantitative food frequency (FFQ, medical and food history questionnaires were also collected and FFQs were then scored using Food Guide Pyramid to obtain the dietary scores. Percent body fat (%BF was measured using bioelectrical impedance analysis (BIA method. Results Female patients had more %BF and lower dietary pattern scores than that of their controls (32 ± 3.6 vs 27.7 ± 4.6 percent and 43.2 ± 11.9 vs 54.5 ± 10.7 points; respectively, p Conclusion Schizophrenia patients have poor nutritional patterns. In particular, female patients have more percent body fat and lower dietary pattern scores compared with their healthy controls. All patients used to consume more fats and sweet drinks frequently. The findings of this study suggest that schizophrenia patients need specific medical nutrition therapies through limiting dietary fats and sugars intakes and weight control. Whether obesity is the consequence of disease, dietary preference or medications used remains to be cleared.

    This study was designed to evaluate the perioperative nutritional status of patients undergoing surgery for gastrointestinal cancer using Subjective Global Assessment and surgeon behavior on nutritional support. We recruited 100 patients undergoing surgery for gastrointestinal cancer in one university and two state teaching hospitals. Subjective Global Assessment was administered to evaluate preoperative and postoperative nutritional status. Fifty-two patients in the state hospitals (Group 1) and 48 in the university hospital were assessed. Anthropometric and biochemical measurements were performed. Changes in preoperative Subjective Global Assessment scores and scores at the time of discharge and types of nutritional support were compared. Subjective Global Assessment-B was regarded as moderate and Subjective Global Assessment-C as heavy malnutrition. Ten patients had Subjective Global Assessment-B and 29 had Subjective Global Assessment-C malnutrition in Group 1 and nine had Subjective Global Assessment-B and 31 had Subjective Global Assessment-C malnutrition in Group 2 during preoperative assessment. Respective numbers in postoperative assessment were 12 for Subjective Global Assessment-B and 30 for Subjective Global Assessment-C in Group 1 and 14 for Subjective Global Assessment-B and 26 for Subjective Global Assessment-C in Group 2. There was no difference between two groups. Nutritional methods according to Subjective Global Assessment evaluation in pre- and postoperative periods were not different between the groups. This study demonstrated that the malnutrition rate is high among patients scheduled for gastrointestinal cancer surgery and the number of surgeons were inadequate to provide perioperative nutritional support. Both university and state hospitals had similar shortcomings. Subjective Global Assessment is an easy and reliable test and if utilized will be helpful to detect patients requiring nutritional support.

All experiments were performed on a commercially available 1.0-T system (Magnetom Impact Expert, Siemens AG, Erlangen, Germany) using a blood oxygen level-dependent (BOLD)-sensitive multi-slice EPI technique (TE 66 ms, 4 mm slice thickness, 210 mm field of view, 64 x 64 acquisition matrix). Different paradigms for localization of the motor cortex and for language lateralization were tested in healthy subjects and patients. Methodological considerations concerning the development of the paradigms are also described. In all healthy subjects, motor activation elicited BOLD signal changes in the sensorimotor cortex, permitting identification of primary motor and sensory cortical areas. Furthermore, focal activation of different cortical areas by a language task was possible in 6 of 10 subjects. Nineteen motor studies were performed in 18 patients with supratentorial lesions, in most cases prior to neurosurgical procedures. In 14 studies, fMRI results demonstrated the localization of the motor hand areas relative to the lesion. The results proved valuable for preoperative planning and contributed to therapeutical decisions. We conclude that functional MRI for clinically relevant applications, such as localization of motor and language function, is feasible even at a field strength of 1.0 T without dedicated equipment.

    Background Previous studies have shown oxidative stress in pemphigus vulgaris and pemphigus foliaceus, nevertheless, it remains unknown whether a similar response is characteristic of endemic pemphigus foliaceus in Peru. Objectives To determine the oxidative stress response in endemic pemphigus foliaceus patients and subjects with positive for anti-desmoglein1 antibodies (anti-dsg1) from endemic areas of Peru. Subjects and Methods This is a cross-sectional study. The study population included 21 patients with Endemic Pemphigus foliaceus and 12 healthy subjects with anti-dsg1 antibodies from the Peruvian Amazon (Ucayali), as well as 30 healthy control subjects. Malondialdehyde, an indicator of lipid peroxidation by free radicals, was measured in serum. Results We collected 21 cases of endemic pemphigus foliaceus, 15 of them with active chronic disease and 6 in clinical remission. Serum malondialdehyde values in patients with chronic active evolution and healthy subjects with anti-dsg1 antibodies were statistically higher than those of healthy controls (p<0.001). There was no significant difference between serum values of localized and generalized clinical forms. Study limitations The main limitation of this present study is the small number of patients with endemic pemphigus and healthy subjects positive for desmoglein 1 antibodies. Conclusions The increased serum levels of malondialdehyde in patients with chronic active endemic pemphigus foliaceus and healthy subjects from endemic areas with anti-dsg1 antibodies may suggest a contribution of systemic lipid peroxidation in the pathogenesis of endemic pemphigus foliaceus.

    Mindfulness and heart coherence training (HCT) training are applied increasingly in the treatment of patients with chronic musculoskeletal pain (CMP). Questionnaires have been developed to assess changes in mindfulness but no gold standard is available. Explore the relationship between changes in mindfulness scores and changes in heart coherence after 3 sessions of HCT in patients with CMP and in healthy subjects. Ten patients with CMP and 15 healthy subjects were trained in self-regulation with the use of HCT following a standardized stress relief program developed by the HeartMath Institute. A heart coherence-score (HC-score) was constructed with scores ranging from 0-100 with higher scores reflecting more heart rate variability (HRV) coherency. Change scores, Spearman correlation coefficients, and Wilcoxon Signed Rank test were calculated to test relationships and differences between HC-score, the Mindfulness Attention and Awareness Scale (MAAS) and Five Facet Mindfulness Questionnaire (FFMQ). A new questionnaire was constructed to explore on which mindfulness-related domains patients with CMP report changes after HCT. Increases were present on HC-score in healthy subjects (Ppilot study, mindfulness as assessed by the MAAS and FFMQ does not appear to improve after HCT. HRV coherency, MAAS, and FFMQ measure different constructs and are weakly related. It is of great importance to choose and develop valid measures that reflect patients' states of mindfulness. Content and face validity of measures of mindfulness may be considered in the light of performance-based measures.

    , blepharospasm, temporal lobe epilepsy with psychosis, enuresis, and perhaps posttraumatic stress disorder (PTSD). Several pharmacological manipulations have been examined for their effects on PPI in healthy human subjects. In some cases, the alterations in PPI produced by these drugs in animals correspond to similar effects in humans. Specifically, dopamine agonists disrupt and nicotine increases PPI in at least some human studies. With some other compounds, however, the effects seen in humans appear to differ from those reported in animals. For example, the PPI-increasing effects of the glutamate antagonist ketamine and the serotonin releaser MDMA in humans are opposite to the PPI-disruptive effects of these compounds in rodents. Considerable evidence supports a high degree of homology between measures of PPI in rodents and humans, consistent with the use of PPI as a cross-species measure of sensorimotor gating. Multiple investigations of PPI using a variety of methods and parameters confirm that deficits in PPI are evident in schizophrenia-spectrum patients and in certain other disorders in which gating mechanisms are disturbed. In contrast to the extensive literature on clinical populations, much more work is required to clarify the degree of correspondence between pharmacological effects on PPI in healthy humans and those reported in animals.

    Inflammatory changes have been described in different affective episodes, as well as in the euthymic phase of Bipolar I Disease. These changes have been proposed as possible peripheral markers of the disease. For this reason well-designed studies are needed to explore this hypothesis. Quantify and compare the serum levels of interleukins (IL) and tumour necrosis factor (TNF) in bipolar I patients and healthy subjects, including the comparison between the affective episodes of the disease. Cross-sectional study including 41 bipolar I patients and 11 healthy control subjects. Serum levels of IL-1B, IL-RA, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12, and TNF were measured during the euthymic, depressive, and manic phases and were compared with the serum levels of the healthy subjects. Manic phase patients had low education and high number of hospitalisations. Depressive phase patients showed high number of depressive episodes throughout life. No statistically significant differences were found in IL and TNF levels between bipolar I patients and healthy controls, or between the bipolar I subgroups (euthymic, manic and depressive states). An increase in the size of the sample is necessary in future studies, in order to enhance the statistical value of the results, and explore the inflammatory hypothesis of the bipolar disease.

  8. The importance of the patient's subjective experience in stroke rehabilitation.

    2011-01-01

    Kaufman's observation that the patients' reactions to their impairments and disabilities need to be addressed in stroke rehabilitation has been shown to be an accurate and perceptive statement. In this article, 3 levels of stroke rehabilitation are outlined, and the importance of focusing on the third level (the level of subjective experience) is emphasized. Identification of the patients' subjective experience allows one to understand what is most frustrating to them. After addressing those frustrations, patients are more eager to engage the rehabilitation process. Within the context of this rehabilitation process, helping patients clarify what their subjective or phenomenological state is as it relates to their stroke is crucial in having them not only engage the rehabilitation process, but ultimately find meaning in life in the face of their stroke. This can be a difficult task because patients often do not have the words to clarify what their inner psychological experiences are following a stroke. Helping to provide guidelines for this can result in a meaningful experience for both the patient and the therapists involved in their care.

The aim of this study is to assess the effect of whole-body cryotherapy on the clinical status of patients with osteoarthritis (OA, according to their subjective feelings before and after the application of a 10-day cold treatment cycle. The aim is also to assess the reduction of intensity and frequency of pain, the reduction of the painkiller medication used, and to assess the possible impact on physical activity. Material and methods : The study involved 50 people, including 30 women (60% and 20 men (40%. Thirty-one patients had spondyloarthritis (62% of respondents, 10 had knee osteoarthritis (20%, and 9 hip osteoarthritis (18%. The overall average age was 50.1 ±10.9 years; the youngest patient was 29 years old and the oldest 73 years old. The average age of the women was 6 years higher. The study used a questionnaire completed by patients, and consisted of three basic parts. The modified Laitinen pain questionnaire contained questions concerning the intensity and frequency of pain, frequency of painkiller use and the degree of limited mobility. The visual analogue scale (VAS was used in order to subjectively evaluate the therapy after applying the ten-day treatment cycle. Results: According to the subjective assessment of respondents, after the whole-body cryotherapy treatments, a significant improvement occurred in 39 patients (78%, an improvement in 9 patients (18%, and no improvement was only declared by 2 patients (4%. Conclusions : Whole-body cryotherapy resulted in a reduction in the frequency and degree of pain perception in patients with osteoarthritis. WBC reduced the number of analgesic medications in these patients. It improved the range of physical activity and had a positive effect on the well-being of patients.

    Type 1 Gaucher disease may be related to the presence of autoantibodies. Their clinical significance is questioned. Primary endpoint was to compare the prevalence of autoantibodies in type 1 Gaucher disease patients with healthy subjects, seeking correlations with autoimmune characteristics. Secondary endpoints were to determine whether patients with autoantibodies reported autoimmunity-related symptoms and if genotype, splenectomy or treatment influenced autoantibodies presence. Type 1 Gaucher disease patients and healthy volunteers were included in this national multicenter exploratory study. Autoantibodies presence was compared in both groups and assessed regarding to genotype, splenectomy, Gaucher disease treatment and autoimmunity-related symptoms. Twenty healthy subjects and 40 type 1 Gaucher disease patients were included. Of the studied group: 15 patients undergone splenectomy, 37 were treated either with enzyme replacement therapy (34) or with substrate reduction therapy (3), 25 were homozygous/heterozygous for the N370S mutation. In type 1 Gaucher disease group (studied group), 52% had positive autoantibodies versus 26% in control group. Antiphospholipid antibodies were more frequent in the studied group (30% vs. 5%), but without correlation to thrombosis, osteonecrosis or bone infarcts. In the studied group, antinuclear antibodies were more frequent (25% vs. 16%). None of the patients with autoantibodies had clinical manifestations of autoimmune diseases. Autoantibodies were not correlated with treatment, genotype, or splenectomy, except for anticardiolipid, more frequent in splenectomized patients. In type 1 Gaucher disease, autoantibodies were more frequent compared to a healthy population. However, they were not associated with an increased prevalence of clinical active autoimmune diseases.

    The relationships bewteen blood flow in the cerebrum and the cerebellum was investigated in 21 normal subjects and 21 patients with dementia of the Alzheimer type (DAT). In normal subjects, only asymmetry in the frontal cortical blood flow was significantly correlated with asymmetry in the contralateral cerebellar blood flow. However, a significant correlation between asymmetry in the cerebral cortical blood flow in many areas and the blood flow in the contralateral cerebellum in DAT patients was observed. These results suggest the existence of a functional relationship between the cerebrum and the cerebellum in both normal and DAT groups, mediated by neuronal mechanisms through crossed fiber pathways. However, there are regional differences in the cerebrocerebellar relationship in normal resting and pathological states. (author).

    Full Text Available Sleep complaints and sleep disturbances are highly prevalent in patients with psychiatric disorders. During hospitalization the patients’ condition may be even worse but little is known about the subjective sleep quality in psychiatric hospitals. Thus, we have investigated subjective sleep quality and mean sleep duration in patients with different psychiatric disorders at the end of hospitalization. For a period of one year, inpatients of a psychiatric hospital with diagnosis of substance use disorder (SUD, schizophrenia (SCZ, or anxiety/depressive disorders (AND were routinely asked to fill in an easily comprehensible sleep quality questionnaire at the end of their hospitalization. Age, gender, subjective sleep quality, and sleep duration were analyzed; sleep duration was classified according to age-specific recommendations. Data of n=309 patients (age 52.1±17.9y, 56.1% women were analyzed (n=63 SUD, n=50 SCZ, n=196 AND. Mean sleep duration was 7.0±2.0 h; 20.7% of patients had sleep durations below and 4.5% above age-specific recommendations. Non-restorative sleep during hospitalization was reported “almost always” in 38.2% (n=118, and “occasionally” in 30.1% (n=93. Subjective sleep quality was significantly associated with sleep duration (rs=−0.31, P<0.0005, but not with age, gender or diagnostic subgroup. The study showed that a great proportion of patients reported poor subjective sleep quality during hospitalization, regardless of age, gender and psychiatric diagnosis. As sleep quality was significantly associated with short sleep duration, a first step could be to take care to achieve recommended age-specific sleep durations in psychiatric hospitals.

  17. The Patient-Worker: A Model for Human Research Subjects and Gestational Surrogates.

    Ryman, Emma; Fulfer, Katy

    2017-01-13

    We propose the 'patient-worker' as a theoretical construct that responds to moral problems that arise with the globalization of healthcare and medical research. The patient-worker model recognizes that some participants in global medical industries are workers and are owed worker's rights. Further, these participants are patient-like insofar as they are beneficiaries of fiduciary relationships with healthcare professionals. We apply the patient-worker model to human subjects research and commercial gestational surrogacy. In human subjects research, subjects are usually characterized as either patients or as workers. Through questioning this dichotomy, we argue that some subject populations fit into both categories. With respect to commercial surrogacy, we enrich feminist discussions of embodied labor by describing how surrogates are beneficiaries of fiduciary obligations. They are not just workers, but patient-workers. Through these applications, the patient-worker model offers a helpful normative framework for exploring what globalized medical industries owe to the individuals who bear the bodily burdens of medical innovation. © 2017 John Wiley & Sons Ltd.

    Full Text Available Handheld devices with touchscreen controls have become widespread in the general population. In this study, we examined the duration estimates (explicit timing made by patients in a major general hospital and healthy control subjects using a custom iPad application. We methodically assessed duration estimates using this novel device. We found that both psychiatric and non-psychiatric patients significantly overestimated time periods compared with healthy control subjects, who estimated elapsed time very precisely. The use of touchscreen-based methodologies can provide valuable information about patients.

  19. Patients with gout differ from healthy subjects in renal response to changes in serum uric acid.

    Liu, Sha; Perez-Ruiz, Fernando; Miner, Jeffrey N

    2017-03-01

    Our objectives were to determine whether a change in serum uric acid (sUA) resulted in a corresponding change in the fractional excretion of uric acid (FEUA) and whether the renal response was different in patients with gout versus healthy subjects. FEUA was calculated from previously published studies and four new phase I studies in healthy subjects and/or patients with gout before and after treatment to lower or raise sUA. Treatments included xanthine oxidase inhibitors to lower sUA as well as infusion of uric acid and provision of a high-purine diet to raise sUA. Plots were created of FEUA versus sUA before and after treatment. For the phase I studies, percent change in FEUA per mg/dL change in sUA was calculated separately for healthy subjects and patients with gout, and compared using Student's t test. Analysis of previously published data and the new phase I clinical data indicates that changing sUA by a non-renal mechanism leads to a change in FEUA. The magnitude of change is greater in subjects with higher baseline FEUA versus patients with gout. Healthy subjects excrete more urate than do patients with gout at physiological urate-filtered load; this difference disappears when the urate-filtered load is decreased to ∼5000mg/24hours. These observations are consistent with a less saturated urate reabsorption system in patients with gout versus healthy subjects, resulting in elevated retention of uric acid. Further investigation could lead to the discovery of mechanisms responsible for the etiology of hyperuricemia/gout. Copyright © 2016 Société française de rhumatologie. Published by Elsevier SAS.

    Untreated celiac disease has traditionally been linked to a greater risk for small intestinal bacterial overgrowth, but the existing evidence is inconclusive. To compare the prevalence of small intestinal bacterial overgrowth in subjects with celiac disease compared with control subjects and patients with irritable bowel syndrome. The study included 15 untreated celiac disease patients, 15 subjects with irritable bowel syndrome, and 15 healthy controls. All enrolled patients underwent a lactulose breath test measuring hydrogen and methane. Small intestinal bacterial overgrowth was defined according to previously published criteria. No differences were found in relation to age or sex. The prevalence of small intestinal bacterial overgrowth was similar between the celiac disease patients and the controls (20 vs. 13.33%, P=NS), whereas it was higher in patients with irritable bowel syndrome (66.66%, Pintestinal bacterial overgrowth between the untreated celiac disease patients and healthy controls.

    Full Text Available Although impaired social functioning, particularly poor employment status, is a cardinal feature of patients with schizophrenia and leads to decreased quality of life (QOL, few studies have addressed the relationship between these two clinical issues. The aim of this study was to determine whether employment status predicts subjective QOL and to evaluate a model in which functional capacity mediates the relationship between general cognitive performance and employment status. Ninety-three patients with schizophrenia were administered a comprehensive battery of cognitive tests, the UCSD Performance-based Skills Assessment-Brief version (UPSA-B, the Social Functioning Scale (SFS, and the Subjective Quality of Life Scale (SQLS. First, we evaluated a model for predicting the employment/occupation subscale score of the SFS using path analysis, and the model fitted well (χ2 (4 = 3.6, p = 0.46; CFI = 1.0; RMSEA < 0.001, with 90% CIs: 0–0.152. Employment status was predicted by negative symptoms and functional capacity, which was in turn predicted by general cognitive performance. Second, we added subjective QOL to this model. In a final path model, QOL was predicted by negative symptoms and employment status. This model also satisfied good fit criteria (χ2 (7 = 10.3, p = 0.17; CFI = 0.987; RMSEA = 0.072, with 90% CIs: 0–0.159. The UPSA-B and SFS scores were moderately correlated with most measures of cognitive performance. These results support the notion that better employment status enhances subjective QOL in patients with schizophrenia.

    The cause of nocturnal awakenings in patients with chronic insomnia is rarely researched. This study prospectively assessed the etiology of nocturnal awakenings (subjectively and objectively) among patients with insomnia at a private, community-based sleep medical center. Twenty adult patients with chronic insomnia enrolled between April 2008 and February 2010 met diagnostic criteria for an insomnia disorder, never previously visited a sleep specialist or underwent sleep testing, and reported no classic sleep disordered breathing symptoms. Patients completed validated scales for insomnia, sleepiness, impairment, anxiety, depression, and quality of life, a qualitative interview to assess subjective reasons for awakenings, and a diagnostic sleep study to objectively assess awakenings and their precipitants. Subjective and objective data showed clinically meaningful insomnia, primarily sleep maintenance insomnia. The most common self-reported reasons for awakenings were: uncertain cause (50%), nightmares (45%), nocturia (35%), bedroom distractions (20%), or pain (15%). No patient identified breathing symptoms as a cause. Objectively, 531 awakenings were observed in the total sample, and 478 (90%) were preceded by sleep breathing events (apnea, hypopnea, or respiratory effort-related event). Fifty-three awakenings were caused by other factors (independent leg jerks [7], spontaneous [14], and sleep that was laboratory-induced [32]). Thirty awakenings ≥ 5 min-a duration sufficient to predispose toward an insomnia episode-were each preceded by a breathing event. Among patients with insomnia with no classic sleep breathing symptoms and therefore low probability of a sleep breathing disorder, most of their awakenings were precipitated by a medical condition (sleep disordered breathing), which contrasted sharply with their perceptions about their awakenings

    Full Text Available The aim of this study was to achieve a better understanding of schizoaffective disorder. Therefore, we obtained electroencephalogram (EEG signals from patients with schizoaffective disorder and analyzed them in comparison to normal subjects.Forty patients with schizoaffective disorder and 40 normal subjects were selected randomly and their electroencephalogram signals were recorded based on 10-20 international system by 23 electrodes in open- and closed-eyes while they were sitting on a chair comfortably. After preprocessing for noise removal and artifact reduction, we took 60- second segments from each recorded signals. Then, the absolute and relative powers of these segments were evaluated in all channels and in 4 frequency bands (i.e., delta, theta, alpha and beta waves. Finally, Data were analyzed by independent t-test using SPSS software.A significant decrease in relative power in the alpha band, a significant decrease in power spectra in the alpha band and a significant increase in power spectra in the beta band were found in patients compared to normal subjects (P < 0.05. The predominant wave in the centro-parietal region was the beta wave in patients, but it was the alpha band in normal subjects (P = 0.048. Also, the predominant wave of the occipital region in patients was the delta wave, while it was the alpha wave in normal subjects (P = 0.038.Considering the findings, particularly based on the significant decrease of the alpha waves in schizoaffective patients, it can be concluded that schizoaffective disorder can be seen in schizophrenia spectrum.

    Full Text Available This study aimed to find parameters to characterize heart rate variability (HRV and discriminate healthy subjects and patients with heart diseases. The parameters used for discrimination characterize the different components of HRV memory (short and long and are extracted from HRV recordings using parametric as well as non parametric methods. Thus, the parameters are: spectral components at low frequencies (LH and high frequencies (HF which are associated with the short memory of HRV and the long memory parameter (d obtained from autoregressive fractionally integrated moving average (ARFIMA models. In the non parametric context, short memory (α1 and long memory (α2 parameters are obtained from detrended fluctuation analysis (DFA. The sample used in this study contains 24-hour Holter HRV recordings of 30 subjects: 10 healthy individuals, 10 patients suffering from congestive heart failure and 10 heart transplanted patients from the Noltisalis database. It was found that short memory parameters present higher values for the healthy individuals whereas long memory parameters present higher values for the diseased individuals. Moreover, there is evidence that ARFIMA modeling allows the discrimination between the 3 groups under study, being advantageous over DFA.

    Research has shown positive effects of music therapy on the physical and mental well-being of terminally ill patients. This study aimed to identify favored subjects and psychosocial needs of terminally ill cancer patients during music therapy and associated factors. Forty-one Patients receiving specialized inpatient palliative care prospectively performed a music therapy intervention consisting of at least two sessions (total number of sessions: 166; per patient average: 4, range, 2-10). Applied music therapy methods and content were not pre-determined. Therapeutic subjects and psychosocial needs addressed in music therapy sessions were identified from prospective semi-structured "field notes" using qualitative content analysis. Patient- and treatment-related characteristics as well as factors related to music and music therapy were assessed by questionnaire or retrieved from medical records. Seven main categories of subjects were identified: "condition, treatment, further care", "coping with palliative situation", "emotions and feelings", "music and music therapy", "biography", "social environment", and "death, dying, and spiritual topics". Patients addressed an average of 4.7 different subjects (range, 1-7). Some subjects were associated with gender (p = .022) and prior impact of music in patients' life (p = .012). The number of subjects per session was lower when receptive music therapy methods were used (p = .040). Psychosocial needs were categorized into nine main dimensions: "relaxing and finding comfort", "communication and dialogue", "coping and activation of internal resources", "activity and vitality", "finding expression", "sense of self and reflection", "finding emotional response", "defocusing and diversion", and "structure and hold". Patients expressed an average of 4.9 psychosocial needs (range, 1-8). Needs were associated with age, parallel art therapy (p = .010), role of music in patient's life (p = .021), and the applied music

    Full Text Available The first goal of this study was to measure the oxidative stress (OS and relate it to lipoprotein variables in 35 renal patients before dialysis (CKD, 37 on hemodialysis (HD and 63 healthy subjects. The method for OS was based on the ratio of cholesteryl esters (CE containing C18/C16 fatty acids (R2 measured by gas chromatography (GC which is a simple, direct, rapid and reliable procedure. The second goal was to investigate and identify a triacylglycerol peak on GC, referred to as TG48 (48 represents the sum of the three fatty acids carbon chain lengths which was markedly increased in renal patients compared to healthy controls. We measured TG48 in patients and controls. Mass spectrometry (MS and MS twice in tandem were used to analyze the fatty acid composition of TG48. MS showed that TG48 was abundant in saturated fatty acids (SFAs that were known for their pro-inflammatory property. TG48 was significantly and inversely correlated with OS. Renal patients were characterized by higher OS and inflammation than healthy subjects. Inflammation correlated strongly with TG, VLDL-cholesterol, apolipoprotein (apo C-III and apoC-III bound to apoB-containing lipoproteins, but not with either total cholesterol or LDL-cholesterol.In conclusion, we have discovered a new inflammatory factor, TG48. It is characterized with TG rich in saturated fatty acids. Renal patients have increased TG48 than healthy controls.

    Full Text Available Personality traits are important candidate predictors of suicidal behavior. Several studies have reported an association between personality/temperament traits and suicidal behavior, suggesting personality traits as intermediary phenotypes related to suicidal behavior. Thus, it is possible that suicide attempts can be accounted for by increased familial rates of risk personality traits. The aim of this work was to evaluate personality traits in affective disorder patients with attempted suicide and to compare them with the personality trait scores of their parents. In addition, ITC scores in the two groups were compared with a healthy control sample. The patients evaluated met the DSM-IV criteria for major depression disorder or dysthymia and had a documented history of suicide attempts. Psychiatric diagnoses of patients and parents were done according to the SCID-I and the personality was assessed using the Temperament and Character Inventory. We analyzed 49 suicide attempt subjects and their parents (n=95 and 89 control subjects. We observed that temperament and character dimensions were similar between patients and their parents (P>0.05. In particular, we observed that high HA and low P, SD, and CO were shared among families. Our study is the first to report that the personality traits of affective disorder patients with a history of attempted suicide are shared between patients and their parents.

    The goal of this study was to clarify the subjective symptoms closely related to Yusho by examining the relationship between the amount of PCB-contaminated rice oil ingested by patients and the subjective symptoms recorded on their questionnaires. The amount of PCB-contaminated rice oil consumed by the patients was obtained by interviewing the housewife in each Yusho family. Individual consumption of the oil was estimated by taking into account age, sex and the number of meals at home. In 1970, 46 patients were available for analysis, and in 1971, 33 patients were available. Among 12 subjective symptoms studied, numbness of the limbs, coughing, expectoration, and the sensation of elevated teeth were considered to show a dose-response relationship, which suggests that these subjective symptoms are closely related to Yusho. Consistent high rates of complaints of general fatigue and eye discharge were considered possibly to be connected with Yusho, although no dose-response relationships have been determined. Other subjective symptoms, such as fever, headache, dizziness, abdominal pain, swelling in the joints, changes in menstruation, and loss of hair failed to show consistent dose-response relationships. It should be noted, however, that for these symptoms which failed to show dose-response relationships, it is impossible to deny a causal relationship.

Matherials: Lumbar lordosis of 420 patients with chronic LBP and 420 asymptomatic subjects was measured by two examiner. A flexible ruler was used to measure lumbar lodosis in all subjects. Results: The averagr degree of lumbar lordosis for all subjects was 37±13°. Females had greater lumbar lordosis (42 ±15° than males (32±100 and elderly subjects had lesser lumbar lordosis than younger and middle aged subjects. Conclussoion: The degree of lumbar lordosis was not differet between normal subjects and those with LBP. It seems that effects of lumbar lordosis on LBP and treatment programs need to be reevaluated.

    Malnutrition is a common problem among cancer patients, usually occurs due to poor appetite, low food intake, and changes in body metabolism. The aim of this study is to determine the prevalence of malnutrition in patients receiving chemotherapy on an outpatient basis. This cross-sectional study conducted on 300 cancer patients referred to hospital. The prevalence of malnutrition among patients was assessed using the abridged scored patient-generated subjective global assessment (abPG-SGA) standard questionnaire. Moreover, patient's weight and 24 h dietary recall were measured. Descriptive statistics were used to present characteristics of patients and dietary recalls. For revealing the correlation, Spearman correlation was used. The average abPG-SGA score was 7.6 (standard deviation [SD] = 5.4) and 60.7% of patients were malnourished and required nutritional intervention. Patients mean age and mean duration of illness were 54.2 (SD = 14.7(years, 25 months, respectively. The most common complaint of patients included fatigue (51.3%), anorexia (43.3%), and dry mouth (41%). Reduction in food intake in past month was reported by 41.7% of patients. According to the high prevalence of cancers and increasing growth of them in recent years with regard to outpatient treatment development for cancer patients, using the abPG-SGA standard questionnaire by nutritionist or nurses can be effective to detect malnourished patients and reduce complications caused by disease.

    Orbital phlebography has been reported to be pathologic in some patients with Tolosa-Hunt's syndrome (recurrent painful ophthalmoplegia). A systematic study of the phlebographic findings in Tolosa-Hunt's syndrome in comparison with a normal material seems not to have been performed. In this investigation, orbital phlebography was performed in 19 patients with Tolosa-Hunt's syndrome and in a reference group of 23 persons without the disease. In 13 of 19 patients (68%) with Tolosa-Hunt's syndrome, the phlebography was pathologic (narrowing or occlusion of particularly the third segment of the superior ophthalmic vein, partial occlusion of the cavernous sinus). Orbital phlebography was normal in all but one of the subjects in the reference group. The medical history of this subject in retrospect revealed symptoms other than painful ophthalmoplegia commonly found in patients with Tolosa-Hunt's syndrome, suggesting that he suffered from a variant of the disease causing the syndrome. In one patient with recurrent painful ophthalmoplegia a biopsy from an eye muscle showed venous vasculitis, probably indicating the basic pathology behind the phlebographic changes in patients with Tolosa-Hunt's syndrome.

    The purpose of this retrospective study was to determine the incidence of missed inferior alveolar nerve (IAN) blocks by using a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine in vital asymptomatic teeth and in emergency patients with symptomatic irreversible pulpitis. As part of 37 studies, 3169 subjects/patients were evaluated for missed IAN blocks. The study included 2450 asymptomatic subjects and 719 emergency patients presenting with symptomatic irreversible pulpitis. Each subject or patient received either a 1- or 2-cartridge volume of 2% lidocaine with 1:100,000 epinephrine. A missed block was defined as no lip numbness at 15-20 minutes after the IAN block. The effect of anesthetic volume on the incidence of missed blocks was assessed by using mixed models logistic regression with individual studies as a random effect. The incidence of missed blocks for asymptomatic subjects was 6.3% for the 1-cartridge volume and 3.8% for the 2-cartridge volume. For patients presenting with irreversible pulpitis, the incidence of missed blocks was 7.7% for the 1-cartridge volume and 2.3% for the 2-cartridge volume. In both asymptomatic subjects and patients with irreversible pulpitis, the 2-cartridge volume was significantly (P = .0395) better than the 1-cartridge volume. There were no significant effects for pulpal diagnosis (P = .7523) or the pulpal diagnosis and anesthetic volume interaction (P = .3973). Concerning missed IAN blocks, we concluded that administration of a 2-cartridge volume was significantly better (P = .0395) than a 1-cartridge volume in both asymptomatic subjects and emergency patients presenting with irreversible pulpitis.

    The aim of this study was to achieve a better understanding of schizoaffective disorder. Therefore, we obtained electroencephalogram (EEG) signals from patients with schizoaffective disorder and analyzed them in comparison to normal subjects. Forty patients with schizoaffective disorder and 40 normal subjects were selected randomly and their electroencephalogram signals were recorded based on 10-20 international system by 23 electrodes in open- and closed-eyes while they were sitting on a chair comfortably. After preprocessing for noise removal and artifact reduction, we took 60- second segments from each recorded signals. Then, the absolute and relative powers of these segments were evaluated in all channels and in 4 frequency bands (i.e., delta, theta, alpha and beta waves). Finally, Data were analyzed by independent t-test using SPSS software. A significant decrease in relative power in the alpha band, a significant decrease in power spectra in the alpha band and a significant increase in power spectra in the beta band were found in patients compared to normal subjects (P schizoaffective patients, it can be concluded that schizoaffective disorder can be seen in schizophrenia spectrum.

    Being submitted to dialysis four hours a day, three times a week can mean experiencing boredom, besides discomfort. Patients often report that the time seems to take longer to go by. The purpose of this study was to explore the influence of two different musical rhythms in the states of mind and perception of adult patients undergoing dialysis, since the literature on this subject is scarce. The study was performed at a private hospital with 43 patients, who participated in two sessions of musical improvisation with a keyboard. The subjective states and perception were evaluated before and after the intervention. Over 80% of the patients felt that time went by faster after the interventions in both rhythms. However, the pace was a decisive factor in the kind of emotional experience that the patients had.

    Using fMRI, we investigated the region of the brain, which was activated by the finger movement tasks (F1) and the recalling finger movement tasks (F2). Six right-handed age-matched healthy controls and six Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) Schizophrenia patients were included in the study. In healthy controls, contralateral motor area, supplementary motor area and somatosensory area were all activated during F1 and F2. However the contralateral parietal lobe (supramarginal gyrus etc) and ipsilateral cerebellum were also activated during F2. In schizophrenia patients, the contralateral motor area was activated during F1, but the activated region was smaller than that observed in healthy subjects. During F2, the bilateral parietal lobes (sensorimotor cortices, association cortex) were activated, while the activated regions were smaller than those seen in healthy controls and no laterality was observed. In addition, no laterality of the activated regions was clearly observed. These results suggest that the function of recalling motor tasks can be mapped onto the contralateral motor area, somatosensory area, supplementary motor area, parietal association cortices, and ipsilateral cerebellum. In schizophrenia patients, the activated regions are smaller than those observed in healthy controls, and parietal regions are also activated bilaterally during recalling motor tasks. Schizophrenia patients may therefore process to recall motor task differently from healthy subjects while also demonstrate less laterality of the brain. (author)

    Full Text Available Background and Aim: Tinnitus represents the perception of sound without an external stimulus. The prevalence of tinnitus ranges from 3% to 30%. In most cases its etiology is unknown. Tinnitus can be classified as pulsatile or nonpulsatile. Nonpulsatile form is the most common form and almost exclusively subjective in nature. There is a range of condition attributed to nonpulsatile high frequency tinnitus (acoustic neuroma, Meniere’s disease, ototoxic agents, and noise exposure, etc. There are many studies about form, site, loudness, and frequency of tinnitus and how it can affect the quality of patient life. Materials and methods: This was a descriptive and analytic study. Thirty-six patients (23 men and 13 women with mean age 53.1 year old with subjective tinnitus evaluated in Pezhvak audiometric clinic in Mashhad.The data consisting of age sex, loudness, frequency form and site of tinnitus. Evaluation of effects of tinnitus on the quality of life and habits was performed with a tinnitus questionnaire (TQ. Results: Tinnitus was unilateral in 64% of cases. The right site was more common. Mean pitch was 7.03 kHz and average loudness was 3.8 dB SPL. SDS was in normal range in all of patients. There was a high frequency sensory neural hearing loss (above the 4 kHz in most of the patients. The greatest score (60.3% of TQ related to intrusiveness aspect. Sleep disorder has the lowest score (39/3%. Global score was 52.4%. Conclusion: Nonpulsatile subjective tinnitus has a broad range of etiology with unknown mechanism in most cases and without any history of underlying disease in a large group of patients. This symptom mostly involves the patients` lifestyle that is intrusiveness aspect in comparison with the other aspects including sleep, hearing and somatic complaints. There is no cure for most patient and more studies are needed in the future.

    Tonsillopharyngitis (sore throat) is a common disease mainly related to the seasonal common cold. To relieve unpleasant symptoms and discomfort of acute tonsillopharyngitis associated with common cold, patients usually take some non-prescription drugs. The primary aim of this study was to assess subjective determinations of the efficacy and the safety/tolerability of an oral spray comprising a combination of lysozyme chloride and cetylpyridinium chloride in those patients. The study involved 1727 patients with tonsillopharyngitis associated with common cold and treated with the studied drug, in the period from December 2014 through March 2015. In total, 95% of patients rated the studied drug to be well, very well and excellently effective. In 32% of patients, the symptoms were relieved 10 minutes after the application of the spray. Significant correlations were found between the two subjective assessments of the drug efficiency with the total of 74.11% (95% CI: 73.41, 77.47%) of patients who said that the feeling of pain in the throat completely disappeared after the drug administration, evaluated the impact/effect of the drug was very good or good (Pearson Chi Square=391.401, p<0.001). The effectiveness was significantly better in patients with up to two episodes of common cold a year (Pearson Chi Square=6.101; p=0.014). The studied drug was rated to be well, very well and excellently tolerated by 97% of patients. According to patients' subjective assessment, the combination of lysozyme chloride and cetylpyridinium chloride in a formulation of spray can quickly, efficiently and safely resolve the symptoms of acute tonsillopharyngitis associated with common cold.

    After anterior cruciate ligament reconstruction (ACLR), relationships between objective measures of muscle function and patient-reported outcomes may change over time. Examining these measures at different time frames after surgery may help develop individualized approaches to improve post-ALCR analysis. To examine the associations between subjective knee function and lower-extremity muscle function in individual patients at various time points after ACLR. Descriptive laboratory study. Fifty-one participants who underwent primary, unilateral ACLR (15 males, 36 females; mean age, 22.9 ± 4.5 years; mean height, 172.4 ± 10.1 cm; mean weight, 68.7 ± 13.1 kg) were separated into 3 groups depending on time since surgery (early, 5 years). Subjective knee function was quantified using the International Knee Documentation Committee (IKDC) subjective knee form and the Knee injury and Osteoarthritis Outcome Score (KOOS). Isometric knee extension and flexion strength were collected at 90 deg/s. Single-leg hop performance was measured using the single hop, triple hop, cross-over hop, and 6-m timed hop. Coefficient correlations were calculated between subjective knee function and objective measures of muscle function for each group. The early group demonstrated moderate correlations between the KOOS and unilateral measures of flexion peak torque ( r = 0.514, P = .035) and flexion power ( r = 0.54, P = .027). The middle group demonstrated the strongest correlations between the KOOS and symmetry measures of the single hop ( r = 0.69, P = .002) and extension work ( r = 0.71, P = .002) as well as unilateral measures of the triple hop ( r = 0.52, P = .034) and extension work ( r = 0.66, P = .004). The late group demonstrated strong correlations between the 6-m timed hop symmetry and the IKDC ( r = 0.716, P = .001) and KOOS ( r = 0.71, P = .001). Patients with a post-ACLR status of less than 2 years exhibited stronger relationships with unilateral strength measures to subjective

    99m Tc-DTPA is a low molecular weight substance, which is believed to pass through the pulmonary epithelium when it is inhaled as an aerosol. We performed 99m Tc-DTPA inhalation studies in 10 nonsmoking normal subjects and 10 patients with biopsy proven idiopathic interstitial pneumonia prior to therapy. 99m Tc-DTPA aerosol was inhaled for 3 min with the subject in the supine position and radioactivity was measured anteriorly with a gamma camera and recorded on computer. Measurements were performed for 3 min with the subject inhaling aerosol and for the subsequent 30 min with the subject in the same position. Time activity curves from the five regions of interest (ROIs) including the entire left lung, the entire right lung, and the upper, middle and lower third of the right lung were separately fitted to a single exponential function for the initial 7 min following cessation of inhalation, and the respective clearance half life (t1/2) in min was calculated. Lung function data, arterial blood gas tensions and blood chemistry were also obtained for comparison with the t1/2 values. The t1/2 values were significantly smaller in all ROIs in patients with idiopathic interstitial pneumonia than in normal subjects, indicating an increased pulmonary epithelial permeability in these patients. There was no relationship between t1/2 and %DL co , %DL co /V A , PaO 2 , or LDH. Although the true pathophysiologic significance of t1/2 measured using 99m Tc-DTPA aerosol is still not known, we consider that this measurement may be an important indicator of nonrespiratory lung function, in particular the degree of alveolar epithelial damage.

    Full Text Available BACKGROUND: Schizophrenia is a heterogeneous disorder with diverse presentations. The current and the proposed DSM-V diagnostic system remains phenomenologically based, despite the fact that several neurobiological and neuropsychological markers have been identified. A multivariate approach has better diagnostic utility than a single marker method. In this study, the mismatch negativity (MMN deficit of schizophrenia was first replicated in a Han Chinese population, and then the MMN was combined with several neuropsychological measurements to differentiate schizophrenia patients from healthy subjects. METHODOLOGY/PRINCIPAL FINDINGS: 120 schizophrenia patients and 76 healthy controls were recruited. Each subject received examinations for duration MMN, Continuous Performance Test, Wisconsin Card Sorting Test, and Wechsler Adult Intelligence Scale Third Edition (WAIS-III. The MMN was compared between cases and controls, and important covariates were investigated. Schizophrenia patients had significantly reduced MMN amplitudes, and MMN decreased with increasing age in both patient and control groups. None of the neuropsychological indices correlated with MMN. Predictive multivariate logistic regression models using the MMN and neuropsychological measurements as predictors were developed. Four predictors, including MMN at electrode FCz and three scores from the WAIS-III (Arithmetic, Block Design, and Performance IQ were retained in the final predictive model. The model performed well in differentiating patients from healthy subjects (percentage of concordant pairs: 90.5%. CONCLUSIONS/SIGNIFICANCE: MMN deficits were found in Han Chinese schizophrenia patients. The multivariate approach combining biomarkers from different modalities such as electrophysiology and neuropsychology had a better diagnostic utility.

    Full Text Available We used perceptual motor tasks involving the learning of mouse control by looking at a Macintosh computer screen. We studied 90 control subjects aged between sixteen and seventy-five years. There was a significant time difference between the scales of age but improvement was the same for all subjects. We also studied 24 patients with Parkinson's disease (PD. We observed an influence of age and also of educational levels. The PD patients had difficulties of learning in all tests but they did not show differences in time when compared to the control group in the first learning session (Student's t-test. They learned two or four and a half times less well than the control group. In the first test, they had some difficulty in initiating the procedure and learned eight times less well than the control group. Performances seemed to be heterogeneous: patients with only tremor (seven and patients without treatment (five performed better than others but learned less. Success in procedural tasks for the PD group seemed to depend on the capacity to initiate the response and not on the development of an accurate strategy. Many questions still remain unanswered, and we have to study different kinds of implicit memory tasks to differentiate performance in control and basal ganglia groups.

    The aim of this study was to examine the role of illness cognitions as a possible pathway between religiousness and subjective health in chronic illness. A sample of 135 chronic cardiac patients completed questionnaires about intrinsic religiousness, frequency of church service attendance, basic illness cognitions (i.e., helplessness, illness acceptance, perceived benefits), and physical and emotional well-being. According to the results, religiousness was significantly associated with subjective health. However, this relationship was indirect, with helplessness and illness acceptance serving as mediators between intrinsic religiousness and health. This finding is significant for understanding the complex relation of religiousness to chronic patients' well-being.

    Measures to keep staff and patients safe (containment) frequently involve coercion. A small proportion of patients is subject to a large proportion of containment use. To reduce the use of containment, we need a better understanding of the circumstances in which it is used and the understandings of patients and staff. Two sweeps were made of all the wards, spread over four hospital sites, in one large London mental health organization to identify patients who had been subject to high levels of containment in the previous two weeks. Data were then extracted from their case notes about their past history, current problem behaviours, and how they were understood by the patients involved and the staff. Nurses and consultant psychiatrists were interviewed to supplement the information from the case records. Twenty-six heterogeneous patients were identified, with many ages, genders, diagnoses, and psychiatric specialities represented. The main problem behaviours giving rise to containment use were violence and self-harm. The roots of the problem behaviours were to be found in severe psychiatric symptoms, cognitive difficulties, personality traits, and the implementation of the internal structure of the ward by staff. Staff's range and depth of understandings was limited and did not include functional analysis, defence mechanisms, specific cognitive assessment, and other potential frameworks. There is a need for more in-depth assessment and understanding of patients' problems, which may lead to additional ways to reduce containment use.

    The present study aims to develop age-dependent cutoff values in a quasi-experimental, cross-sectional diagnostic test study. One hundred and twenty (120) asymptomatic subjects (n = 100, 36♀, 18 75 years, for normative values; n = 20, 23-75 years, 15♀, for selectivity analyses) and 20 patients suffering from idiopathic neck pain (selectivity analyses, 22-71 years, 15♀) were included. Subjects performed five repetitive maximal cervical flexion/extension movements in an upright sitting position. Cervical kinematic characteristics (maximal range of motion (ROM), coefficient of variation (CV) and mean conjunct movements in rotation and flexion (CM)) were calculated from raw 3D ultrasonic data. Regression analyses were conducted to reveal associations between kinematic characteristics and age and gender and thus to determine normative values for healthy subjects. Age explains 53 % of the variance in ROM (decrease 10.2° per decade), 13 % in CV (increase 0.003 per decade) and 9 % in CM (increase 0.57° per decade). Receivers operating characteristic (ROC) analyses were conducted for differences between individual values of the kinematic characteristics and normative values to optimise cutoff values for distinguishing patients from unimpaired subjects (20 patients and 20 healthy). Cutoff values distinguished asymptomatic subjects' and chronic nonspecific neck patient's movement characteristics with sufficient quality (sensitivity 70-80 %, specificity 65-70 %). By including such classifications, the present findings expand actual research stating an age-related decrease in kinematic behaviour only using categorising span widths across decades. Future study is warranted to reveal our results' potential applicability for intervention onset decision making for idiopathic neck pain patients.

    The aim of this study was to examine relationships among subjective cognitive complaints, psychosocial factors and nursing work function in nurses providing direct patient care. Cognitive functioning is a critical component for nurses in the assurance of error prevention, identification and correction when caring for patients. Negative changes in nurses' cognitive and psychosocial functioning can adversely affect nursing care and patient outcomes. A descriptive correlational design with stratified random sampling. The sample included 96 nurses from the major geographic regions of the United States. Over 9 months in 2016-2017, data were collected using a web-based survey. Stepwise multiple linear regression analyses were used to examine relationships among subjective cognitive complaints, psychosocial factors and nursing work function. Overall, participants reported minimal work function impairment and low levels of subjective cognitive complaints, depression and stress. In multivariate analyses, depression was not associated with nurses' work function. However, perceived stress and subjective concerns about cognitive function were associated with greater impairment of work function. Nurses experiencing subjective cognitive complaints should be encouraged to address personal and environmental factors that are associated with their cognitive status. Additionally, stress reduction in nurses should be a high priority as a potential intervention to promote optimal functioning of nurses providing direct patient care. Healthcare institutions should integrate individual and institutional strategies to reduce factors contributing to workplace stress. © 2017 John Wiley & Sons Ltd.

However, no attempt has been made to establish an iterative measurement of 6MWD during the overall period of pulmonary rehabilitation. Therefore, the aim of this study was to evaluate the impact of a twelve-week rehabilitation program on the iterative weekly measurement of 6MWD in chronic obstructive pulmonary disease (COPD patients and healthy subjects.Methods: Twenty-six patients with COPD and nine age-matched healthy subjects were studied. Measurements were taken at baseline and after twelve weeks except for the 6MWD. The exercise measurements included a six-minute walking test (6MWT and an incremental exercise test. Oxygen saturation, heart rate, and dyspnea will be monitored during all these tests. Results: At baseline there were significant differences between groups, except in age, body mass index, and oxygen saturation. After 12 weeks, there was no significant change in lung function in patients with COPD and healthy subjects. The 6MWD, peak oxygen uptake VO2peak and anaerobic threshold increased significantly after training in both groups (P < 0.01. The averaged trace of the 6MWD of patients with COPD and healthy subjects was followed-up respectively by a logarithmic and linear fitting. 6MWD showed a plateau after eight weeks in patients with COPD, however, it increased continually overall in healthy subjects.Conclusion: Both patients with COPD and healthy subjects demonstrated functional responses to training but with

Coronary flow reserve (CFR is a physiological index of coronary microcirculation and is noninvasively measured by transthoracic Doppler echocardiography (TTDE. This study aimed to investigate the effects of RIC on CFR in healthy subjects and patients with HF, through the assessment by TTDE. Methods: Ten patients with HF with left ventricular ejection fraction of less than 40%, and ten healthy volunteers were enrolled in this study. RIC treatment was performed twice a day for 1 week. Our custom-made RIC device was programmed to automatically conduct 4 cycles of 5 minutes inflation and 5 minutes deflation of a blood pressure cuff to create intermittent arm ischemia. CFR measurements and laboratory tests were examined before, and after 1 week of RIC treatment. Results: One week of RIC treatment was well tolerated in both groups. RIC treatment increased CFR from 4.0±0.9 to 4.6±1.3 (mean ± standard deviation in healthy subjects (P=0.02, and from 1.9±0.4 to 2.3±0.7 in patients with HF (P=0.03, respectively. Systolic blood pressure in healthy subjects, and heart rate in HF patients decreased after RIC treatment (both P<0.01. Conclusion: This study demonstrated that a 1 week course of RIC treatment improved coronary microcirculation in healthy subjects and patients with HF associated with reduced left ventricular ejection fraction.

    Although prior studies identified a relationship between cognitive insight and subjective quality of life (QOL) in patients with schizophrenia, the brain regions mediating this relationship remain unknown. Recent studies have shown that the ventrolateral prefrontal cortex may be particularly important for cognitive insight in individuals with schizophrenia. Here, we examined whether frontotemporal function mediates the relationship between cognitive insight and QOL in 64 participants, including 32 patients with schizophrenia and 32 healthy controls. Cognitive insight was measured using the Beck Cognitive Insight Scale (BCIS), while participants' subjective QOL was assessed using the Medical Outcomes Study 36-item Short-form Health Survey. Frontotemporal function was evaluated during a verbal fluency task using multichannel near-infrared spectroscopy. Consistent with previous findings, we found that frontotemporal function was impaired in patients with schizophrenia. Interestingly, our data also revealed that the right ventrolateral PFC and the right anterior part of the temporal cortex significantly mediated the relationship between the self-reflectiveness (SR) subscale of the BCIS and subjective QOL. These findings suggest that cognitive insight, particularly SR, is associated with subjective QOL in patients with schizophrenia via right frontotemporal function. The findings of this study provide important insight into a QOL model of schizophrenia, which may guide the development of cost-effective interventions that target frontotemporal function in patients with schizophrenia.

    Full Text Available Recently the attention for mirror exercises in therapies targeted specifically to body experience concerns has increased. This retrospective study will explore the mirror behaviour of anorexia nervosa (AN, bulimia nervosa (BN and non-clinical female subjects (CG and investigate whether mirror avoidance or checking are related to negative body experiences.The group of eating disorders consisted of 560 AN and 314 BN patients. The control group consisted of 1151 female subjects. The Body Attitude Test and the Eating Disorder Inventory subscales drive for thinness and body dissatisfaction were used. To explore the mirror behaviour, one item of the Body Attitude Test ‘I am observing my appearance in the mirror’ was used. Nonparametric analyses (Spearman rho correlations, Kruskal-Wallis and Mann Whitney test were used because of the categorical data.BN patients observed their body more often in the mirror than AN patients and the control subjects do. Age and BMI showed no significant main effect of mirror frequency. The relation between the frequency of mirror behaviour and body experience were significant but low (under .40. AN patients and control subjects with a mirror checking behaviour had a more negative body experience than those with mirror avoidance behaviour. In the BN group, no differences were found.There is support to integrate mirror exercises in a treatment of eating disorder patients. From a clinical point, mirror exercises are preferably combined with a body oriented therapy within a multidimensional cognitive behavioural approach. Recommendations for mirror exercises based on the clinical experience are given.

    Full Text Available Background/Aim. Tacrolimus concentration-dose ratio as a potential therapeutic drug monitoring strategy was suggested to be used for the patients subjected to renal transplantation. The aim of this study was examining the relationship between tacrolimus concentration-dose ratio, suggested to be used as a therapeutic drug monitoring strategy and the polymorphisms of genes encoding the most important enzymes, such as CYP3A5 and CYP3A4, as well as the transporter P-glycoprotein, for its metabolism and elimination. Methods. The study was designed as a prospective case series study, in which the unit of monitoring was the outpatient examination of 54 patients subjected to renal transplantation. Genotyping was performed by 7500 Real- Time PCR System by assessing allelic discrimination based on TaqMan® methodology. Results. Patients (n = 13 who were treated with less than 2 mg of tacrolimus/day (0.024 ± 0.006 mg/kg/day had the tacrolimus concentration-dose ratio larger than 150 ng/mL/mg/kg. In this group, 84.62% patients had CYP3А5 *3*3 allele. All of these patients had CYP3А4 *1*1/*1*1B allele. Regarding ABCB1 C3435T gene, 30.77% of patients had the TT gene variant, while 69.23% of our patients had CC and CT gene variants. Conclusion. Tacrolimus concentration-dose ratio greater than 150 ng/mL/mg/kg is cut-off value in patients subjected to renal transplantation which might point to patients who are poor CYP3A5 metabolizers and/or with dysfunctional P-glycoprotein.

    We studied 24-h rhythms of acid production and alkalization in 30 patients with duodenal ulcer (DU) and 30 healthy subjects using upper endoscopic examination and computer intragastric pH-metry. Gastric acid production was higher in DU patients and was more intensive in the daytime than at night. Healthy subjects had low and monotonous acid production. In DU decompensation of alkalization in the antral stomach and suppression of duodenogastric reflux is total. In healthy subjects antrum alkalization is more evident and intensive at night due to, among other causes, duodenogastric reflux.

    Remitted schizophrenic patients living in the community often encounter difficulties in their daily lives, possibly leading to the development of social anxiety symptoms. Although several studies have reported the significance of social anxiety as a comorbidity in patients with schizophrenia, few longitudinal data are available on the development of social anxiety symptoms in patients with remitted schizophrenia, especially in association with the process of "deinstitutionalization." The aims of this study were to assess the social anxiety symptoms in remitted outpatients with schizophrenia and to examine whether the development of social anxiety symptoms was associated with psychotic symptoms, social functioning, or subjective quality of life. Fifty-six people with schizophrenia who were discharged through a deinstitutionalization project were enrolled in this longitudinal study and prospectively assessed with regard to their symptoms, social functioning, and subjective quality of life. The severity of social anxiety symptoms was measured using the Liebowitz Social Anxiety Scale (LSAS). Global/Social functioning and subjective quality of life were evaluated using the Global Assessment of Functioning Scale, the Social Functioning Scale, and the World Health Organization-Quality of Life 26 (WHO-QOL26). Thirty-six patients completed the reassessment at the end of the 5-year follow-up period. The mean LSAS total score worsened over time, whereas other symptoms improved from the baseline. The mean WHO-QOL26 score in the worsened LSAS group was significantly lower than that in the stable LSAS group. At baseline, WHO-QOL26 scores were associated with an increase in the severity of social anxiety symptoms. In community-dwelling patients with remitted schizophrenia, a lower subjective quality of life might lead to the development of social anxiety symptoms, both concurrently and prospectively. To achieve a complete functional recovery, additional interventions for social

    A comparative study was made on the possibility of the qualitative evaluation of osteoporosis and one of the methods of its quantitative determination in patients with secondary hyperparathyroidism. 25 patients with chronic renal insufficiency, subjected to prolonged hemodialysis, were examined. It is concluded that the effectiveness of the qualitative methods for the evaluation of changes in the bones was sufficiently high, while the method proposed by Barnett and Nordin for diagnosing osteoporosis proved to be inadequate. These data were confirmed by checking the index in patients with primary hyperparathyroidism

    Context: Although electroconvulsive therapy (ECT) is considered a very effective tool for the treatment of psychiatric diseases, memory disturbances are among the most important adverse effects. Aims: This study aimed to assess prospectively early subjective memory complaints in depressive and manic patients due to bilateral, brief-pulse ECT, at different stages of the treatment, compare the associations between psychiatric diagnosis, sociodemographic characteristics, and ECT characteristics. Settings and Design: This prospective study was done with patients undergoing ECT between November 2008 and April 2009 at a tertiary care psychiatry hospital of 2000 beds. Materials and Methods: A total of 140 patients, scheduled for ECT with a diagnosis of bipolar disorder (depressive or manic episode) or unipolar depression according to Diagnostic and Statistical Manual of Mental Disorders IV diagnostic criteria, were included in the study and invited to complete the Squire Subjective Memory Questionnaire (SSMQ) before ECT, after the first and third sessions and end of ECT treatment. Statistical Analysis: Mean values were compared with the Kruskal–Wallis test and comparison of the longitudinal data was performed with a nonparametric longitudinal data analysis method, F1_LD_F1 design. Results: SSMQ scores of the patients before ECT were zero. SSMQ scores showed a decrease after the first and third ECT sessions and before discharge, showing a memory disturbance after ECT and were significantly less severe in patients with mania in comparison to those with depression. Conclusions: These findings suggest an increasing degree of subjective memory complaints with bilateral brief-pulse ECT parallel to the increasing number of ECT sessions. PMID:27385854

    This study aimed to investigate whether the serial position effects in memory can differentiate patients with different subtypes of mild cognitive impairment (MCI) from healthy controls and patients with different stages of Alzheimer's disease (AD). The serial position effects was tested with the CERAD word list task in 184 persons (39 healthy control subjects, 15 amnestic MCI single domain subjects, 23 amnestic MCI multiple domain subjects, 31 nonamnestic MCI subjects, 45 early or mild AD patients, and 31 moderate AD patients). With progression of dementia, memory deficits increased and the impairment in the primacy effect during the learning trials advanced, whereas the recall of recent items was less impaired. The serial position profile of nonamnestic MCI patients resembled that of healthy control subjects, whereas amnestic MCI patients showed poorer performance in all 3 positions but no significant difference as a function of serial word position. Analyses of the serial position effect may be a useful complement to clinical neuropsychological measures for distinguishing amnestic MCI patients from normal aging and patients with different stages of dementia. © 2013 S.

    Recent research on Parkinson's disease (PD) has emphasized that parkinsonian movement, although bradykinetic, shares many attributes with healthy behavior. This observation led to the suggestion that bradykinesia in PD could be due to a reduction in motor motivation. This hypothesis can be tested in the framework of optimal control theory, which accounts for many characteristics of healthy human movement while providing a link between the motor behavior and a cost/benefit trade-off. This approach offers the opportunity to interpret movement deficits of PD patients in the light of a computational theory of normal motor control. We studied 14 PD patients with bilateral subthalamic nucleus (STN) stimulation and 16 age-matched healthy controls, and tested whether reaching movements were governed by similar rules in these two groups. A single optimal control model accounted for the reaching movements of healthy subjects and PD patients, whatever the condition of STN stimulation (on or off). The choice of movement speed was explained in all subjects by the existence of a preset dynamic range for the motor signals. This range was idiosyncratic and applied to all movements regardless of their amplitude. In PD patients this dynamic range was abnormally narrow and correlated with bradykinesia. STN stimulation reduced bradykinesia and widened this range in all patients, but did not restore it to a normal value. These results, consistent with the motor motivation hypothesis, suggest that constrained optimization of motor effort is the main determinant of movement planning (choice of speed) and movement production, in both healthy and PD subjects.

    Melanoma patients exhibit changes in immune responsiveness in the local tumor environment, draining lymph nodes, and peripheral blood. Immune-targeting therapies are revolutionizing melanoma patient care increasingly, and studies show that patients derive clinical benefit from these newer agents. Nonetheless, predicting which patients will benefit from these costly therapies remains a challenge. In an effort to capture individual differences in immune responsiveness, we are analyzing patterns of gene expression in human peripheral blood cells using RNAseq. Focusing on CD4+ peripheral blood cells, we describe multiple categories of immune regulating genes, which are expressed in highly ordered patterns shared by cohorts of healthy subjects and stage IV melanoma patients. Despite displaying conservation in overall transcriptome structure, CD4+ peripheral blood cells from melanoma patients differ quantitatively from healthy subjects in the expression of more than 2000 genes. Moreover, 1300 differentially expressed genes are found in transcript response patterns following activation of CD4+ cells ex vivo, suggesting that widespread functional discrepancies differentiate the immune systems of healthy subjects and melanoma patients. While our analysis reveals that the transcriptome architecture characteristic of healthy subjects is maintained in cancer patients, the genes expressed differentially among individuals and across cohorts provide opportunities for understanding variable immune states as well as response potentials, thus establishing a foundation for predicting individual responses to stimuli such as immunotherapeutic agents.

    This paper investigated whether Alzheimer's disease (AD) patients may demonstrate a discrepancy between subjective autobiographical reliving and objective recall. To this end, 31 AD patients and 35 controls were asked to retrieve three autobiographical memories. For each memory, participants were asked to rate its subjective characteristics (e.g., reliving, travel in time, visual imagery…). Besides this subjective assessment, we analyzed recall objectively with regard to specificity. Results showed poorer subjective autobiographical reliving and objective recall in AD patients than in controls. A discrepancy (i.e., higher level of subjective reliving than of objective recall) was observed in AD but not in control participants. Despite a compromise in their objective recall, AD patients seemed to attribute a high value to their subjective autobiographical experience. This discrepancy can be attributed to a potential genuine consciousness experience in which mild AD patients can, to some extent, experience some subjective features of the past.

    The aim of this study was to analyze the efficiency of the voice therapy in children with vocal nodules by using the acoustic analysis and subjective assessment. Thirty-nine patients with vocal fold nodules, aged between 7 and 14, were included in the study. Each subject had voice therapy led by an experienced voice therapist once a week. All diagnostic and follow-up workouts were performed before the voice therapy and after the third or the sixth month. Transoral and/or transnasal videostroboscopic examination and acoustic analysis were achieved using multi-dimensional voice program (MDVP) and subjective analysis with GRBAS scale. As for the perceptual assessment, the difference was significant for four parameters out of five. A significant improvement was found in the acoustic analysis parameters of jitter, shimmer, and noise-to-harmonic ratio. The voice therapy which was planned according to patients' needs, age, compliance and response to therapy had positive effects on pediatric patients with vocal nodules. Acoustic analysis and GRBAS may be used successfully in the follow-up of pediatric vocal nodule treatment.

    The effect of acute changes in the delivery rate of glutamine to the kidney on urinary ammonium excretion was studied in man. Healthy subjects and patients with intrinsic renal disease were studied under three different acid-base conditions: unaltered acid-base balance; NH(4)Cl-induced acidosis; and NaHCO(3)-induced alkalosis. Anhydrous L-glutamine was administered orally in a single dose of 260 mmoles during each of these three acid-base states. We found that endogenous venous plasma glutamine concentration fell during acidosis and rose during alkalosis in both healthy subjects and patients with renal disease. In healthy subjects, orally administered glutamine raised plasma glutamine concentration markedly over a 2-3 hr period. This was accompanied by an increase in urinary ammonium excretion and a rise in urine pH under normal acid-base conditions and during metabolic acidosis. No increase in ammonium excretion occurred when glutamine was administered during metabolic alkalosis in spite of an equivalent rise in plasma glutamine concentration. In patients with renal disease, endogenous venous plasma glutamine concentration was lower than in healthy subjects, perhaps as a result of mild metabolic acidosis. Acute oral glutamine loading failed to increase urinary ammonium excretion significantly during either unaltered acid-base conditions or after NH(4)Cl-induced acidosis, even though plasma glutamine rose as high as in healthy subjects. We conclude from these observations that glutamine delivery to the kidney is a rate-limiting factor for ammonium excretion in healthy subjects, both before and after cellular enzyme adaptation induced by metabolic acidosis. In contrast, in patients with renal disease, glutamine delivery is not rate-limiting for ammonium excretion. Presumably other factors, such as surviving renal mass and the activity of intracellular enzymes necessary for ammonia synthesis limit ammonium excretion in these patients.

    Schizophrenia has a strong genetic component that is relevant to the understanding of the pathophysiology of the syndrome. Thus, recent investigations have shifted from studies of diagnosed patients with schizophrenia to examining their unaffected relatives. Previous studies found that during language processing, relatives thought to be at genetic high-risk for the disorder exhibit aberrant functional activation in regions of language processing, specifically in the left inferior frontal gyrus (Broca's area). However, functional connectivity among the regions involved in language pathways is not well understood. In this study, we examined the functional connectivity between a seed located in Broca's area and the remainder of the brain during a visual lexical decision task, in 20 schizophrenia patients, 21 subjects at genetic high risk for the disorder and 21 healthy controls. Both the high-risk subjects and patients showed significantly reduced activation correlations between seed and regions related to visual language processing. Compared to the high-risk subjects, the schizophrenia patients showed even fewer regions that were correlated with the seed regions. These results suggest that there is aberrant functional connectivity within cortical language circuitry in high-risk subjects and patients with schizophrenia. Broca's area, which is one of the important regions for language processing in healthy controls, had a significantly reduced role in the high-risk subjects and patients with schizophrenia. Our findings are consistent with the existence of an underlying biological disturbance that begins in genetically at risk individuals and progresses to a greater extent in those who eventually develop schizophrenia.

    Objective: To study the significance of serum osteocalcin changes in healthy subjects and pathological conditions. Methods: The levels of S-BGP were measured with RIA in 270 normal subjects of different age groups (every 10 yrs as an age group), 60 patients with carebrovascular disease (CVD) and 85 patients with metabolic bone disease. Results: (1) The mean value of S-BGP in umbilical blood was 19.3 +- 16.8 μg/L (n = 89), in 3 day sold newborn infant was 7.4 +- 2.3 μg/L (n = 22), in healthy subjects (from 11 to 60 yrs, average age 39 yrs) was 5.2 +- 1.35 μg/L (n = 100), 5.3 +- 1.4 μg/L (n = 47) in males and 5.1 +- 1.34 μg/L (n = 53) in females. In old healthy subjects the mean value was 3.9 +- 1.48 μg/L (n = 30). The level of S-BGP was negatively correlated with the age significantly (r = -0.383, P < 0.001).

    Full Text Available CONTEXT: Most patients subjected to liver transplantation presents hypersplenism, which is reversed after the operation. However, some patients remain with moderate to intense hypersplenism. OBJECTIVES: To study the effect of liver transplantation on platelet count in patients with hypersplenism. METHOD: Of a total of 233 patients who underwent liver transplantation, 162 were excluded from the present study because of occurrence of steroid-resistant rejection, absence of hypersplenism before the transplantation, absence of follow-up for at least 2 years or incomplete exams data. The electronic study protocols of the remaining 71 patients were reviewed to determine the demographics, etiology of cirrhosis, and results of pathologic examination of the explanted liver. Serial platelet count was obtained from the study protocol on the day before liver transplantation and 1, 2, 4, and 6 months and 1 year after liver transplantation. Statistical analysis was performed using the Student's t-test, chi-square test, and Spearman's correlation test. RESULTS: Posttransplant platelet count at all time intervals was significantly higher than the pretransplant value (P100,000/mm³ in 58 patients (81.7% 1 month after liver transplantation. Twelve patients (16.9% remained with thrombocytopenia 1 year after liver transplantation. Three patients (4.2% had recurrence of thrombocytopenia within 1 year after liver transplantation. There was no correlation between pretransplant platelet count and the Child-Pugh class or the MELD score. CONCLUSION: Liver transplantation reverses hypersplenism in most patients.

    Fourteen subjects (4 with testicular feminization, 2 mothers, 1 aunt and 1 father of these patients, 2 normal women, 2 normal men and 2 normal prepubertal boys) were given 0.1 to 0.2 g/kg of 50 percent 15 N-labeled NH 4 Cl before and after 6 daily injections of testosterone (T) 15 mg/m 2 ). In 24-hour urine specimens collected on the test days, 15 N was calculated from total N (Kjeldahl) and the percentage of 15 N (mass spectrometry or 15 N-analyzer Isocommerz). In all normal subjects, urinary 15 N-balance was influenced positively by T (+31.3 +- 8.4 percent), in prepubertal boys more (+43 to +66 percent) than in women (+20 to +30 percent) and men (+6 to +23). In testicular feminization, 15 N-balance not only failed to become more positive, but was even reduced (-24.7 +- 17.6 percent). The father of a patient had only a slight response (+7 percent) as one of the normal males, probably because of higher endogenous T-levels in adult males. One mother and the aunt had no response (-7.4 to + 1.5 percent). In the mother, the balance became slightly positive (+10 percent) on oral contraceptives. The other mother, who was on estrogen treatment prior to and during the test, had a positive but insufficient change of balance (+17 percent). It is concluded that this test allows detection of patients with testicular feminization and possibly also healthy female carriers. In these cases, estrogen treatment appears to positively influence the response to T

    Depressive symptoms are prevalent and cause adverse outcomes in heart failure. Previous studies have linked depressive symptoms with socioeconomic status. However, little is known about the mechanisms underlying this relationship. This study aimed to evaluate the association between socioeconomic status and depressive symptoms, and to examine whether access to healthcare, health literacy and social support mediated this relationship in patients with heart failure. Cross-sectional design was used to study 321 patients with heart failure recruited from a general hospital. Demographics, clinical data, depressive symptoms, socioeconomic status (i.e., education, employment, income, and subjective social status), access to healthcare, health literacy, and social support were collected by patient interview, medical record review or questionnaires. A series of logistic regressions and linear regressions were conducted to examine mediation. The mean age of patients with heart failure was 63.6±10.6years. Fifty-eight patients (18%) had depressive symptoms. Lower subjective social status (OR=1.321, p=0.012) and lower health literacy (OR=1.065, psubjective social status and health literacy were entered simultaneously, the relationship between subjective social status and depressive symptoms became non-significant (OR=1.208, p=0.113), demonstrating mediation. Additionally, lower social support was associated with depressive symptoms (OR=1.062, p=0.007). In patients with heart failure, health literacy mediated the relationship between subjective social status and depressive symptoms. Lower social support was associated with depressive symptoms. Interventions should take these factors into account. Copyright © 2016 Elsevier Inc. All rights reserved.

    Everybody knows that all protein calorie malnutrition is not only the cause of death in cancer patients but also affects the good performance treatment as well as their quality of life. Because of that common complication, it is necessary the use of simple tools to detect its occurrence. A recent study called NUPAC perceive that 52% of patients in advanced stages presents protein calorie malnutrition. The tool used was the subjective global valuation which is generated by the patient and is based on clinical parameters. The Eastern Cooperative Oncology Group showed that a weight loss predicts the treatment response reducing the survival and quality of life. In 2002 a study carried out in the Nutritional Support Unit, University Hospital Vall d'Hebron in Barcelona recorded that at admission only 16,7% of patients were within normal nutritional values, 38.9% were undernourished moderate and 44.4% severe malnutrition, nutritional assessment at discharge showed no significant changes in relation to income hospital. 81.2% of these patient had a prescribed diet v / o of which 43.1% needed some supplements type and only 23% an artificial diet. The valuation method used was also generated by the subjective global valuation patient. Considering the impact that the nutritional status has in the evolution of neoplastic disease we saw the need to make a job using the above tool applied by personnel out of the nutrition in order to evaluate and identify patients who need or no simple nutritional intervention. Our study was conducted in the period of August-October in 2004 and included 50 users, of both sexes (26 males and 24 females) treated with polychemotherapy (which were excluded in the first series of MDT) and either ambulatory or hospitalized at transplant unit or conventional sector in Hematology-Oncology Service at the Asociacion Espanola Primera de Socorros Mutuos. Part of the questionnaire was completed by the own user and It also were performed by anthropometric

    Under certain conditions, coercive interventions in psychotic patients can help to regain insight and alleviate symptoms, but can also traumatize subjects. This study explored attitudes towards psychiatric coercive interventions in healthy individuals and persons suffering from schizophrenia, schizoaffective or bipolar disorder. The impact of personal history of coercive treatment on preferences concerning clinical management of patients unable to consent was investigated. Six case vignettes depicting scenarios of ethical dilemmas and demanding decisions in favour of or against coercive interventions were presented to 60 healthy volunteers and 90 patients. Structured interviews focusing on experienced coercion were performed in conjunction with the Coercion Experience Scale and the Admission Experience Survey. Symptom severity, psychosocial functioning and insight into illness were assessed as influencing variables. Student's t tests compared patients' and controls' judgments, followed by regression analyses to define the predictive value of symptoms and measures of coercion on judgments regarding the total patient sample and patients with experience of fixation. Patients and non-psychiatric controls showed no significant difference in their attitudes towards involuntary admission and forced medication. Conversely, patients more than controls significantly disapproved of mechanical restraint. Subjective experience of coercive interventions played an important role for the justification of treatment against an individual's "natural will". Factors influencing judgments on coercion were overall functioning and personal experience of treatment effectiveness and fairness. Qualitative and quantitative aspects of perceived coercion, in addition to insight into illness, predicted judgments of previously fixated patients. Results underline the importance of the quality of practical implementation and care, if coercive interventions cannot be avoided.

    Brain-derived neurotrophic factor (BDNF) is a neurotrophic factor with an important role in the regulation of body weight, body mass index (BMI) and obesity. Increased BMI that leads to obesity is a substantial risk factor for coronary heart disease (CHD). The functional BDNF Val66Met polymorphism (rs6265) has been associated with CHD, obesity and BMI. The aim of the study was to determine the association between BDNF rs6265 polymorphism and CHD and/or BMI in patients with CHD and healthy control subjects. The study included 704 Caucasian subjects: 206 subjects with CHD and 498 healthy control subjects. The BDNF rs6265 genotype frequency was similar in male and female subjects, and there were no differences in the frequency of the BDNF rs6265 genotypes in 206 patients with CHD and in 498 healthy subjects. When study participants were subdivided according to the BMI categories into normal weight, overweight and obese subjects, significantly different BDNF rs6265 genotype frequency was found within healthy subjects, but not within patients with CHD. Healthy subjects, but not patients with CHD, subdivided into carriers of the Met/Met, Met/Val and Val/Val genotype, had different BMI scores. The BDNF rs6265 genotype frequency was similar in male and female subjects, and there were no differences in the frequency of the BDNF rs6265 genotypes in 206 patients with CHD and in 498 healthy subjects. When study participants were subdivided according to the BMI categories into normal weight, overweight and obese subjects, significantly different BDNF rs6265 genotype frequency was found within healthy subjects, but not within patients with CHD. Healthy subjects, but not patients with CHD, subdivided into carriers of the Met/Met, Met/Val and Val/Val genotype, had different BMI scores. BDNF rs6265 polymorphism was not associated with a diagnosis of CHD or with BMI categories among patients with CHD. In contrast, healthy Caucasians, carriers of the BDNF Met/Met genotype, had more

    Full Text Available Background . The provision of medical services to patients according to their expectations and needs is necessary for the comfort and quality of life of patients, as well as for the standardization of hospital procedures. In recognizing these needs and expectations, an important step is the verification of provided services in order to improve their quality. The present study was designed to determine differences in service quality, as evaluated by hospitalized patients. Objectives . The analysis of the subjective feelings of hospitalized patients concerning service quality in the context of the application of the SER VQUAL method – a pilot study. Material and methods. The study was conducted in a Lower Silesian hospital in a group of 29 young patients (women: 16, men: 13, average age: 16 diagnosed with kidney disease. In the study a standard sheet of 22 SER VQUAL statements was used, and an analysis of the validity of 5 quality areas important for the patient was conducted. Results. According to the respondents, the most important of all 5 features directly affecting the quality of life during treatment is the ability and skill of the ward staff to provide medical services, so-called reliability – 24.48%. In turn, the least important of all the study characteristics was the aesthetics and ergonomics of rooms, the presence of appropriate equipment, the so-called material dimension – 15.31%. Furthermore, service quality gaps were visible in all five service quality dimensions. Conclusions . 1. The SER VQUAL method helps to identify discrepancies between the perceptions of patients’ expectations in all dimensions of the quality of provided medical services. 2. For the patients the least important is the material dimension, and the most affecting is the dimension associated with the reliability of the medical services. 3. Improvement of the level of satisfaction with the quality of medical services requires proper planning and effective

    Full Text Available Objectives: Muscle blood flow in the forearm of patients with rheuma-toid arthritis and healthy volunteers following treatment with temperature increasingarm baths, mudpacks and short- or decimeter-wave diathermy was studied in thisinvestigation. The aim of the study was to find out the difference of reactive hyperemia between the different temperature methods as well as the influence on theconsensual reaction. Subjects: Eighty patients with rheumatoid arthritis, stage 3 according toSteinbrocker, as well as 80 healthy human subjects had been assigned numerically in the four therapy- and controlgroups. Patients with diseases influencing the peripheral blood flow were excluded. Design: Blood flow was measured by venous occlusion plethysmography in both forearms with the subjects lyingsupine. The application of the local heat therapies had been excluded on the left forearm. The forearm blood flow wasmonitored before heat therapy, directly after as well as in two further 10 minutes intervals. An analysis of variancewas used to determine the influence on blood flow of the response to the heat therapies in patients with rheumatoidarthritis and healthy subjects.Results: Under homogeneous starting conditions and a statistically uniformed high blood flow in rest the reactive values of blood flow on the left-hand side of application and the right consensual side showed high significant differencesbetween all methods of therapy. Differences between the patients and the healthy subjects only showed tendencies withpartially lower reactions, concerning the patients with rheumatoid arthritis. All methods of heat therapy caused a statistically provable consensual reaction that turned out smaller after diathermic methods. Here the post therapeuticreaction of the blood flow on the side of application was also lower or rather shorter. Conclusion: Greater differences of the blood flow in rest between the patients with rheumatoid arthritis and healthysubjects

    A new method is described for quantitative measurement of the uptake of sup(99m)Tc-methylene diphosphonate (MDP) by the sacro-iliac joints. The method uses 'regions of interest' providing advantages over the previously described 'slice' method; the two methods are compared in normal subjects, patients with known sacro-iliitis and patients with low back pain. Sacro-iliac activity, as calculated by the sacro-iliac index (SII) in normal patients, was shown to decrease with age in females but not in males. The SII was compared with radiographs of the sacro-iliac joints in the patients with known sacro-iliac joint disease and in those with low back pain. The method is useful for the exclusion of sacro-iliitis as a specific cause of back pain. (author)

    Full Text Available The neural correlates of motor inhibition leading to paresis in conversion disorder are not well known. The key question is whether they are different of those of normal subjects feigning the symptoms. Thirteen conversion disorder patients with hemiparesis and twelve healthy controls were investigated using functional magnetic resonance tomography under conditions of passive motor stimulation of the paretic/feigned paretic and the non-paretic hand. Healthy controls were also investigated in a non-feigning condition. During passive movement of the affected right hand conversion disorder patients exhibited activations in the bilateral triangular part of the inferior frontal gyri (IFG, with a left side dominance compared to controls in non-feigning condition. Feigning controls revealed for the same condition a weak unilateral activation in the right triangular part of IFG and an activity decrease in frontal midline areas, which couldn't be observed in patients. The results suggest that motor inhibition in conversion disorder patients is mediated by the IFG that was also involved in inhibition processes in normal subjects. The activity pattern in feigning controls resembled that of conversion disorder patients but with a clear difference in the medial prefrontal cortex. Healthy controls showed decreased activity in this region during feigning compared to non-feigning conditions suggesting a reduced sense of self-agency during feigning. Remarkably, no activity differences could be observed in medial prefrontal cortex for patients vs healthy controls in feigning or non-feigning conditions suggesting self-agency related activity in patients to be in between those of non-feigning and feigning healthy subjects.

    The purpose of this prospective multi-institutional study was to evaluate the nutritional status of patients undergoing radiotherapy (RT) for treatment of head and neck, lung, or gastrointestinal cancer. A total of 1,000 patients were enrolled in this study at seven different hospitals in Seoul, Korea between October 2009 and May 2010. The nutritional status of patients after receiving 3 weeks of RT was evaluated using subjective global assessment (SGA). The nutritional status of each patient was rated as well nourished (A), moderately malnourished (B), or severely malnourished (C). The mean age of patients in this study was 59.4 ± 11.9 years, and the male to female ratio was 7:3. According to the SGA results, 60.8%, 34.5%, and 4.7% of patients were classified as A, B, or C, respectively. The following criteria were significantly associated with malnutrition (SGA B or C; p < 0.001): loss of subcutaneous fat or muscle wasting (odds ratio [OR], 11.473); increased metabolic demand/stress (OR, 8.688); ankle, sacral edema, or ascites (OR, 3.234); and weight loss 5% (OR, 2.299). SGA was applied successfully to assess the nutritional status of most patients. The prevalence of malnutrition in a radiation oncology department was 39.2%. The results of this study serve as a basis for implementation of nutrition intervention to patients being treated at radiation oncology departments.

    Full Text Available Background In this study we assessed the relationship between corrected-QT intervals and other ECG characteristics with methadone dose and other parameters in MMT patients and healthy subjects. Methods This was a case-control study which was carried out on patients underwent MMT and healthy control group who had been referred to Ebne-Sina academic hospital, Mashhad during 2014 - 2015. At the time of the study, 40 patients who received MMT therapy for at least 6 months and 40 voluntary healthy subjects who matched on age and sex enrolled in the study. 12-lead ECG was performed for all the patients. Mean QT interval, PR interval and QRS duration in every 12 leads were documented for each patient in maximum. Results To evaluate the patients, we divided 80 patients into two groups: 40 patients under treatment with Methadone and 40 voluntary participants as control group. There were 20 males and 20 females in each group. Duration of addiction was 214.80 ± 126.99 months in MMT group. Significant differences were observed in PRi between the patient and control groups (P = 0.007, and also between methadone dose and PRi (r = 0.468, P = 0.038 in males. QTc prolongation was reported in 4 patients of addicted group (10%. All of the QTc prolongation patients were female (P = 0.037. There was significant relationship between PRi and weight (P = 0.015, addiction period (P = 0.011, methadone treatment period (P = 0.018 as well as methadone dosage (P = 0.14. Methadone cut off point of 65 mg had a significant relationship with systolic blood pressure (P = 0.002, diastolic blood pressure (P = 0.013, QTCi (P = 0.016 and QRS (P = 0.044; however, no significant relationship was reported with PRi (P = 0.451. Conclusions We found that there is no exact dosage of methadone in which the side effects such as TdP (Torsade de pointes or QTc prolongation can be predicted. Female gender and methadone dosage ≥ 65 mg were risk factors of our study for QTc prolongation which

Occupational stress may hamper a successful return to work, so cancer survivors should be given the opportunity to address occupational stress issues before returning to work. We investigated the amount of occupational stress among cancer patients and whether it is associated with their well-being, their subjective need for occupational rehabilitation and elevations in their risk of early retirement. At the beginning of rehabilitation, we asked cancer patients to respond to occupation-related and health-related questionnaires. We used t-tests, chi-square tests, and logistic regression analyses to address our research questions. A total of 477 patients participated in the study. Of these, 19% were occupationally stressed, and 26% reported subjective need for occupational rehabilitation. Patients who reported work-related stress had a diminished quality of life, were more likely to report subjective need for occupational rehabilitation (OR = 2.16), and had a higher risk of early retirement (OR = 5.44). Furthermore, cancer patients reported deficits in both active coping abilities and mental stability at work. Because occupational stress is associated with a higher risk of early retirement, both patients and physicians should take work-related problems seriously. Screening patients for occupational stress may help physicians identify patients who are at risk of experiencing problematic work re-entries. Furthermore, the results of the study suggest that cancer patients might have problems maintaining confidence in their abilities to solve work-related problems. Therefore, facilitating the development of a perception of self-efficacy might be an important treatment goal. Copyright © 2012 John Wiley & Sons, Ltd.

    Full Text Available The aim of this study was to examine differences in brain neural activation in response to monosodium glutamate (MSG, the representative component of umami, between patients with bulimia nervosa (BN and healthy women (HW controls. We analyzed brain activity after ingestion of an MSG solution using functional magnetic resonance imaging (fMRI in a group of women with BN (n = 18 and a group of HW participants (n = 18. Both groups also provided a subjective assessment of the MSG solution via a numerical rating scale. The BN group subjectively rated the MSG solution lower in pleasantness and liking than the control group, although no difference in subjective intensity was noted. The fMRI results demonstrated greater activation of the right insula in the BN group versus the control group. Compared with the HW controls, the BN patients demonstrated both altered taste perception-related brain activity and more negative hedonic scores in response to MSG stimuli. Different hedonic evaluation, expressed as the relative low pleasing taste of umami tastant and associated with altered insula function, may explain disturbed eating behaviors, including the imbalance in food choices, in BN patients.

    Full Text Available Context: There is a paucity of literature regarding the effects of thyroid disorders on the oral cavity by influencing the salivary gland function. Aims: This study aims to understand the qualitative and quantitative changes that thyroid disorder can cause in the salivary function. Settings and Design: After obtaining ethical clearance, 46 consecutive newly diagnosed thyroid dysfunction patients were enrolled in this cross-sectional study, along with 45 age-and sex-matched controls. Subjects and Methods: Unstimulated and stimulated salivary flow rates, pH, and buffering capacity of the whole saliva were studied in addition to subjective oral dryness in the study participants. Statistical Analysis Used: The independent t-test was employed to compare the means between the two groups and Pearson's Chi-square test was used to assess the goodness of fit. Results: The findings showed that females are more affected with thyroid disorders and that hypothyroidism is more commonly reported than hyperthyroidism. A significant reduction in the salivary flow rates and buffering capacity was observed among the affected group compared to the controls, whereas the salivary pH did not show significant differences between genders and also between the case and control groups. A feeling of subjective oral dryness was perceived by many affected patients. Conclusions: The study was able to establish an association between thyroid dysfunction and salivary gland function. We hope that this study leads to more high-impact research in this field as salivary diagnostics is gaining more popularity with every passing day.

    The area of the corpus callosum (CC) on midsagittal spin-echo sequence magnetic resonance (MR) scans was measured in 64 normal subjects and 12 patients with Alzheimer's disease (AD). The normal subjects consisted of 32 males and 32 females, aged 25 to 83 years old. There was no significant age difference between males and females. Fifty-five out of the 64 subjects were right-handed (RH) and 9 were left-handed or ambidextrous (NRH). Among patients with AD, 5 were males and 7 were females, aged 53 to 79 years old. Diagnosis of AD was performed mainly based on clinical history, magnetic resonance image (MRI) and positron emission tomographic findings. The outline of the CC on midsagittal MR film was traced and the total callosal sectional area (CCT) as well as the anterior half (CCA), posterior half (CCP) and posterior 5th or splenium (CCS) area measurements were performed using a planimeter. In either normal males or females, the CCA showed a significant negative correlation with age, but the CCP and the CCS did not correlate with age. Total CC (CCT) area was 691.2±91.0 sq. mm for the whole group and no difference was found between males and females. When the CC area was normalized with respect to the midsagittal area of the supratentorial portion of the brain (MSB), females were found to have a large CC than males. No portion of the CC area was significantly different between RH and NRH subjects in absolute or normalized measures. Compared with 36 age-matched normals, patients with AD had smaller MSB and each portion of the CC, with significant reduction in the CCA and the CCT. In conclusion, relationships between age, sex and the size of the CC have been found, providing some insights into the connectivity of the human brain. Characteristics of white matter loss in AD were also clarified in this study. (author)

    Objective: We discuss the use of levothyroxine for excessive daytime sleepiness (EDS) and prolonged nocturnal sleep time in a euthyroid patient with narcolepsy. Methods: After failure of first-line narcolepsy treatments, a 48-year-old female began levothyroxine (25 mcg/day). After 12 weeks of treatment, the patient was evaluated for improvement in total sleep time and subjective daytime sleepiness assessed by Epworth Sleepiness Scale (ESS). Results: At baseline, ESS score was 16 and total sleep time averaged 16 h/day. After 12 weeks, ESS was 13 and reported total sleep time was 13 h/day. Conclusions: Levothyroxine improved EDS and total sleep time in a euthyroid patient with narcolepsy without cataplexy after 12 weeks without side effects. Citation: Sobol DL, Spector AR.

    Full Text Available Abstract Background Both obesity and type 2 diabetes are associated with hypovitaminosis D. The aims of this study were to investigate the association of serum 25-hydroxy vitamin D (25(OH D and parathyroid hormone (PTH concentration with body mass index (BMI in type 2 diabetic patients compared to control subjects and their predicting role in obesity. Methods This cross-sectional study was conducted on 200 subjects (100 type 2 diabetics and 100 healthy controls. Concentration of 25(OH D, calcium, phosphorous, parathyroid hormone (PTH, fasting blood glucose, HbA1c, serum insulin, homeostasis model assessment of insulin resistance (HOMA-IR was determined in the fasting samples. Anthropometric measurements including body mass index (BMI were also measured. Results Eighty-five percent of type 2 diabetics and 79% of healthy subjects were suffering from vitamin D deficiency or insufficiency. Serum concentration of 25(OH D (22.08 ± 15.20 ng/ml (r = −0.11, P = 0.04 and calcium (8.94 ± 0.59 mg/dl (r = −2.25, P = 0.04 has significant statistically with BMI in type 2 diabetic patients. Serum concentration of PTH has non-significantly associated with BMI in diabetic patients and healthy subjects. Conclusion Serum levels of vitamin D inversely and PTH positively are associated with BMI after adjusted for age, gender and serum calcium in both type 2 diabetic patients and healthy subjects. These associations were statistically significant for serum concentration of vitamin D and calcium only in diabetic patients. So the status of vitamin D is considered as an important factor in type 2 diabetic patients.

  15. Putative transcriptomic biomarkers in the inflammatory cytokine pathway differentiate major depressive disorder patients from control subjects and bipolar disorder patients.

    Timothy R Powell

    Full Text Available Mood disorders consist of two etiologically related, but distinctly treated illnesses, major depressive disorder (MDD and bipolar disorder (BPD. These disorders share similarities in their clinical presentation, and thus show high rates of misdiagnosis. Recent research has revealed significant transcriptional differences within the inflammatory cytokine pathway between MDD patients and controls, and between BPD patients and controls, suggesting this pathway may possess important biomarker properties. This exploratory study attempts to identify disorder-specific transcriptional biomarkers within the inflammatory cytokine pathway, which can distinguish between control subjects, MDD patients and BPD patients. This is achieved using RNA extracted from subject blood and applying synthesized complementary DNA to quantitative PCR arrays containing primers for 87 inflammation-related genes. Initially, we use ANOVA to test for transcriptional differences in a 'discovery cohort' (total n = 90 and then we use t-tests to assess the reliability of any identified transcriptional differences in a 'validation cohort' (total n = 35. The two most robust and reliable biomarkers identified across both the discovery and validation cohort were Chemokine (C-C motif ligand 24 (CCL24 which was consistently transcribed higher amongst MDD patients relative to controls and BPD patients, and C-C chemokine receptor type 6 (CCR6 which was consistently more lowly transcribed amongst MDD patients relative to controls. Results detailed here provide preliminary evidence that transcriptional measures within inflammation-related genes might be useful in aiding clinical diagnostic decision-making processes. Future research should aim to replicate findings detailed in this exploratory study in a larger medication-free sample and examine whether identified biomarkers could be used prospectively to aid clinical diagnosis.

    Full text: While the effects of positioning on the distribution of ventilation in the lungs of younger subjects has been relatively well investigated, this is not so in the older age group. Known age-associated changes in the respiratory system are proposed to alter the distribution of ventilation in the lungs of older people. The aim of the present study was therefore to determine the effects of positioning on the distribution of ventilation in the lungs of older normal subjects. The distribution of ventilation in upright sitting and right side lying was measured in ten subjects using Technegas lung ventilation during tidal breathing. In the upright sitting position ventilation was preferentially distributed to the middle and basal regions (dependent regions). Right side lying ventilation was preferentially distributed to the right lung (dependent region). These results suggest that preferential distribution of ventilation to the dependent lung regions in older subjects is mainly due to the gravity-dependent gradient in pleural pressure. It is proposed that this distribution may partly result from loss of elasticity in the lungs with ageing. Predominantly, the distribution of ventilation in the lungs of older normal subjects in our study is similar to that previously described in younger subjects (Amis et al., 1984, Kaneko et al, 1966, Milic-Emili et al, 1966. This suggests that a similar pleural pressure gradient may exist in the lungs of older and younger subjects. This is an important implication as the majority of patients that physiotherapists treat with cardiopulmonary dysfunction are in the older age group. Further research is required to determine the effects of positioning on the distribution of ventilation in older patients with cardiopulmonary dysfunction to enable direct clinical implications to be made.

    The kinetics of unconjugated 14 C-bilirubin metabolism have been investigated and analysed in terms of a three-pool model in a group of seven normal subjects and in a group of eight cirrhotic patients who had appreciable impairment of liver cell function. The results indicate that, in patients with compensated cirrhosis, the efficiency of the liver in extracting unconjugated bilirubin from plasma against a concentration gradient is impaired, even though the liver's capacity to conjugate bilirubin may be normal. As a consequence of the increased volume of distribution, the absolute hepatic clearance of unconjugated bilirubin is relatively well maintained. (author)

    The present study showed clinical and imaging particularities of primary headache to subjects with multiple sclerosis. From the total number of 28 patients included in this study 22 (78,57%) had headache accuses (3 men and 19 women). Was observed a high prevalence of tension type headache, present to 10 of the 22 patients (45.45%). Migraine was diagnosed to 8 respondents (36.36 %). In 4 cases was found a combination of migraine and tension type headache (8.1%). Headache was more common to women with multiple sclerosis (MS) than to men. Neuroimaging of MS patients indicates the fact that the presence of demyelinating disease in the brainstem, midbrain, periaqueductal gray substance is associated with an increased risk of headache, migraine characteristics (migraine-like). Psychometric test have revealed a high level of depression and anxiety in patients with MS and chronic headache. (authors)

    The use of complementary and alternative medicine has increased over the past decade. The aim of this study was to evaluate whether homeopathy influenced global health status and subjective wellbeing when used as an adjunct to conventional cancer therapy. In this pragmatic randomized controlled trial, 410 patients, who were treated by standard anti-neoplastic therapy, were randomized to receive or not receive classical homeopathic adjunctive therapy in addition to standard therapy. The study took place at the Medical University Vienna, Department of Medicine I, Clinical Division of Oncology. The main outcome measures were global health status and subjective wellbeing as assessed by the patients. At each of three visits (one baseline, two follow-up visits), patients filled in two different questionnaires. 373 patients yielded at least one of three measurements. The improvement of global health status between visits 1 and 3 was significantly stronger in the homeopathy group by 7.7 (95% CI 2.3-13.0, p=0.005) when compared with the control group. A significant group difference was also observed with respect to subjective wellbeing by 14.7 (95% CI 8.5-21.0, p<0.001) in favor of the homeopathic as compared with the control group. Control patients showed a significant improvement only in subjective wellbeing between their first and third visits. Results suggest that the global health status and subjective wellbeing of cancer patients improve significantly when adjunct classical homeopathic treatment is administered in addition to conventional therapy.

    Poor sleep is common among patients with medical disorders. Sleep disturbances can be a cause of fatigue and poor quality of life for patients suffering from sarcoidosis. Studies on subjective sleep quality or prevalence of insomnia have not been reported so far. The aim of this study was to investigate the subjectively reported sleep quality and its relation to psychological and physical factors in sarcoidosis patients. 1197 patients from Germany diagnosed with sarcoidosis were examined using the Pittsburgh Sleep Quality Index (PSQI), the Medical Research Council (MRC) dyspnea scale, the Hospital Anxiety and Depression Scale (HADS) and the Multidimensional Fatigue Inventory (MFI). 802 patients (67%) had PSQI global scores >5, indicating subjectively poor quality of sleep. The mean PSQI score was 7.79 ± 4.00. Women reported a significantly inferior individual quality of sleep than men. The subjective quality of sleep was lowered significantly with increasing dyspnea for men and women. 294 patients (25%) had PSQI global scores >10 usually found in patients with clinically relevant insomnia. In this group 86% had high values for fatigue, 69% for anxiety, and 59% for depression. The prevalence of known sleep apnea was 8.7% and 15.7% for restless legs. Poor subjective sleep quality in sarcoidosis patients is about twice as common as in the general population and is associated with fatigue, anxiety, depression and dyspnea. Questions about sleep complaints should therefore be included in the management of sarcoidosis. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Background Sleep disorder is one of the most common non-motor symptoms in Parkinson's disease (PD patients. At present, there are subjective and objective tools to evaluate sleepdisorders. Nevertheless, previous studies commonly used single subjective questionnaires or objective examinations. Therefore, we used the combinations of subjective and objective tools to analyze clinical characteristics of sleep disturbances in PD and investigated differences and consistence between subjective and objective tools. Methods One hundred and sixteen PD patients were eligible to participate into this study. All participants were evaluated by Pittsburgh Sleep Quality Index (PSQI, Unified Parkinson's Disease Rating Scale (UPDRS in "on" condition, Hoehn-Yahr (H-Y stage, Hamilton Depression Rating Scale (HAMD 24 items, Montreal Cognitive Assessment (MoCA, Epworth Sleepiness Scale (ESS, and underwent a video-polysomnography (Video-PSG. Results According to PSQI score of 116 PD patients, the proportion of PD patients with sleep disturbances (PSQI ≥ 7 was 50% (N = 58. Compared to PD patients without sleep disturbances, PD patients with sleep disturbances had lower score of MoCA (23.34 ± 3.50 vs 24.89 ± 3.52; t = 2.377, P = 0.019, higher score of UPDRSⅠ[4.00 (2.00, 5.00 vs 3.00 (2.00, 5.00; U = - 2.306, P = 0.021], UPDRSⅡ[12.00 (9.00, 16.00 vs 10.00 (6.00, 13.00; U = - 1.995, P = 0.046], higher levodopa equivalent daily dose [LED, (508.14 ± 335.85 vs (394.06 ± 236.40 mg/d; t = - 2.115, P = 0.037]. Although PD patients with sleep disturbances had more score of UPDSR Ⅲ and higher H-Y stage, the differences were not significant (P > 0.05. On the other hand, decreased total sleep time (TST, reduced sleep efficiency (SE, increased sleep latency (SL, decreased non-rapid eye movement (NREM sleep stage Ⅱ time were found for PD patients with sleep disturbances (P 0.05, for all. The score of PSQI was positively correlated with the score of ESS (r = 0.200, P = 0

    Diagnosing depression in the early curable stages is very important and may even save the life of a patient. In this paper, we study nonlinear analysis of EEG signal for discriminating depression patients and normal controls. Forty-five unmedicated depressed patients and 45 normal subjects were participated in this study. Power of four EEG bands and four nonlinear features including detrended fluctuation analysis (DFA), higuchi fractal, correlation dimension and lyapunov exponent were extracted from EEG signal. For discriminating the two groups, k-nearest neighbor, linear discriminant analysis and logistic regression as the classifiers are then used. Highest classification accuracy of 83.3% is obtained by correlation dimension and LR classifier among other nonlinear features. For further improvement, all nonlinear features are combined and applied to classifiers. A classification accuracy of 90% is achieved by all nonlinear features and LR classifier. In all experiments, genetic algorithm is employed to select the most important features. The proposed technique is compared and contrasted with the other reported methods and it is demonstrated that by combining nonlinear features, the performance is enhanced. This study shows that nonlinear analysis of EEG can be a useful method for discriminating depressed patients and normal subjects. It is suggested that this analysis may be a complementary tool to help psychiatrists for diagnosing depressed patients. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Purpose AV-45 amyloid biomarker is known to show uptake in white matter in patients with Alzheimer’s disease (AD) but also in healthy population. This binding; thought to be of a non-specific lipophilic nature has not yet been investigated. The aim of this study was to determine the differential pattern of AV-45 binding in healthy and pathological populations in white matter. Methods We recruited 24 patients presenting with AD at early stage and 17 matched, healthy subjects. We used an optimized PET-MRI registration method and an approach based on intensity histogram using several indexes. We compared the results of the intensity histogram analyses with a more canonical approach based on target-to-cerebellum Standard Uptake Value (SUVr) in white and grey matters using MANOVA and discriminant analyses. A cluster analysis on white and grey matter histograms was also performed. Results White matter histogram analysis revealed significant differences between AD and healthy subjects, which were not revealed by SUVr analysis. However, white matter histograms was not decisive to discriminate groups, and indexes based on grey matter only showed better discriminative power than SUVr. The cluster analysis divided our sample in two clusters, showing different uptakes in grey but also in white matter. Conclusion These results demonstrate that AV-45 binding in white matter conveys subtle information not detectable using SUVr approach. Although it is not better than standard SUVr to discriminate AD patients from healthy subjects, this information could reveal white matter modifications. PMID:24573658

    (1) To assess the degree of focal cartilage abnormalities in physically active and sedentary healthy subjects as well as in patients with early osteoarthritis (OA). (2) To determine the diagnostic value of T2 and T1rho measurements in identifying asymptomatic physically active subjects with focal cartilage lesions. Thirteen asymptomatic physically active subjects, 7 asymptomatic sedentary subjects, and 17 patients with mild OA underwent 3.0-T MRI of the knee joint. T1rho and T2 values, cartilage volume and thickness, as well as the WORMS scores were obtained. Nine out of 13 active healthy subjects had focal cartilage abnormalities. T1rho and T2 values in active subjects with and without focal cartilage abnormalities differed significantly (p<0.05). T1rho and T2 values were significantly higher (p<0.05) in early OA patients compared to healthy subjects. T1rho measurements were superior to T2 in differentiating OA patients from healthy subjects, yet T1rho was moderately age-dependent. (1) Active subjects showed a high prevalence of focal cartilage abnormalities and (2) active subjects with and without focal cartilage abnormalities had different T1rho and T2 composition of cartilage. Thus, T1rho and T2 could be a parameter suited to identify active healthy subjects at higher risk for developing cartilage pathology. (orig.)

    Purpose: The reproducibility of corticospinal diffusion tensor tractography (DTT) for a guideline is important before longitudinal monitoring of the therapy effects in stroke patients. This study aimed to establish the reproducibility of corticospinal DTT indices in healthy subjects and chronic hemiparetic stroke patients. Materials and methods: Written informed consents were obtained from 10 healthy subjects (mean age 25.8 ± 6.8 years), who underwent two scans in one session plus the third scan one week later, and from 15 patients (mean age 47.5 ± 9.1 years, 6–60 months after the onset of stroke, NIHSS scores between 9 and 20) who were scanned thrice on separate days within one month. Diffusion-tensor imaging was performed at 3 T with 25 diffusion directions. Corticospinal tracts were reconstructed using fiber assignment by continuous tracking without and with motion/eddy-current corrections. Intra- and inter-rater as well as intra- and inter-session variations of the DTT derived indices (fiber number, apparent diffusion coefficient (ADC), and fractional anisotropy (FA)) were assessed. Results: Intra-session and inter-session coefficients of variations (CVs) are small for FA (1.13–2.09%) and ADC (0.45–1.64%), but much larger for fiber number (8.05–22.4%). Inter-session CVs in the stroke side of patients (22.4%) are higher than those in the normal sides (18.0%) and in the normal subjects (14.7%). Motion/eddy-current correction improved inter-session reproducibility only for the fiber number of the infarcted corticospinal tract (CV reduced from 22.4% to 14.1%). Conclusion: The fiber number derived from corticospinal DTT shows substantially lower precision than ADC and FA, with infarcted tracts showing lower reproducibility than the healthy tissues

    A consistent management algorithm for subjective tinnitus remains to be elucidated. Chronic tinnitus yields approximately US$2110 in annual health care costs per patient. However, it is unclear whether spending more in the management of tinnitus equates with greater patient satisfaction. Thus, the aim of this study is to correlate patient satisfaction with patient demographics, provider recommendations, and total health care-related expenditures. A retrospective chart review and a patient satisfaction questionnaire. All data were collected from a large Midwestern hospital. Patients were included who presented to the tinnitus clinic during the year 2011 and were between the ages of 18 and 89 years. They were excluded with diagnoses of Ménière's disease, pulsatile tinnitus, acoustic neuromas, or autoimmune inner ear diseases. The retrospective data and satisfaction surveys were entered by 3 of the authors. Responses were based on Likert scales. Of the 692 patients included, 230 completed and returned the satisfaction questionnaire (33.2% response rate), yielding an overall mean of $662.60 charges. The frequency of intervention recommendations per patients ranged from 0 to 13, with a median of 4. Spearman's correlations did not result in significant correlations between patient satisfaction and number of clinic visits (P=.499) or associated charges (P=.453). Given that the variability among provider recommendations, the high overall mean of tinnitus-related charges, and patient satisfaction was not related to costs, further research is needed examining patient preference in the treatment of tinnitus. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Craniometric studies have shown that both Chiari malformation (CM) and basilar invagination (BI) belong to a spectrum of malformations. A more precise method to differentiate between these types of CVJM is desirable. The Chamberlain's line violation (CLV) is the most common method to identify BI. The authors sought to clarify the real importance of CLV in the spectrum of craniovertebral junction malformations (CVJM) and to identify possible pathophysiological relationships. We evaluated the CLV in a sample of CVJM, BI, CM patients and a control group of normal subjects and correlated their data with craniocervical angular craniometry. A total of 97 subjects were studied: 32 normal subjects, 41 CM patients, 9 basilar invagination type 1 (BI1) patients, and 15 basilar invagination type 2 (BI2) patients. The mean CLV violation in the groups were: The control group, 0.16 ± 0.45 cm; the CM group, 0.32 ± 0.48 cm; the BI1 group, 1.35 ± 0.5 cm; and the BI2 group, 1.98 ± 0.18 cm. There was strong correlation between CLV and Boogard's angle (R = 0.82, P = 0.000) and the clivus canal angle (R = 0.7, P = 0.000). CM's CLV is discrete and similar to the normal subjects. BI1 and BI2 presented with at least of 0.95 cm CLV and these violations were strongly correlated with a primary cranial angulation (clivus horizontalization) and an acute clivus canal angle (a secondary craniocervical angle).

    Do patients with bi- or trimalleolar ankle injury show differences in motor skills and safety in comparison with healthy, active, age-matched control subjects? Prospective controlled cross-sectional study. Inclusion of 17 patients with bi- or trimalleolar ankle injury (mean 1.5 years postsurgery) and 23 healthy, active subjects of comparable age (fitness studio). Measurement instruments: motor test procedures and questionnaires. Comparison of patients and control subjects by routine daily motor function: patients  0.05), fear of falling: patients > controls (p = 0.003) and physical activity: patients motor deficits in activities of daily life between the patients and controls, only tendencies; however, the patients showed definite limitations with an increased fear of falling and a reduced physical activity compared with the healthy control group. The resulting differences should be positively influenced by appropriate enhancement of training or participation in sports courses. The aim is to achieve a similar quality of life by a perception of safety and trust in one's own motor skills.

    Full Text Available Background. The aim of this study was to assess the subjective cure rate after the tension-free vaginal tape (TVT procedure in patients with stress (SUI and mixed (MUI urinary incontinence.Methods. This is a questionnaire based study done in 43 patients with SUI and 52 patients with MUI. In the assessement of the subjective cure rate the visual analogue scale and the symptom assessment index (SAI were used. Data were analyzed using nonparametric statistics.Results. The subjective cure rate assessed 19.6 months after TVT amounted to 89.3%. Urinary incontinence after TVT procedure was noted in 26 patients (27.4% and the majority of these women (73.1% were diagnosed with MUI. In patients with SUI and postoperative stable bladder a higher success rate was observed (96.7%. In 18.6% patients with SUI, de novo overactive bladder symptoms occurred. These patients estimated a significantly (p = 0.027 lower cure rate (81.9% after TVT procedure. In patients with MUI, the cure rate after TVT amounted to 85.6%. The subjective cure rate was lower (79.4% in case of persistent overactive bladder symptoms. However, it was significantly higher (97.5% in case of a postoperatively stable bladder (p = 0.016. In the group of MUI patients, the symptoms of overactive bladder disease resolved spontaneously in 17 patients (32.7% postoperatively. The patients were satisfied with TVT and 92.6% would recommend this procedure to others.Conclusions. The TVT procedure is a very effective method of treatment for stress as well as mixed urinary incontinence. The success rate of the procedure is high, however, it is influenced by bladder activity.

    Carotenoids are colored molecules that are widespread in the plant kingdom, but animals cannot synthesize them. Carotenes are long, apolar molecules which require fully functioning digestive processes to be absorbed properly. Hence they could be interesting markers of intestinal absorption and digestion. Indeed, only few tests are available to assess these processes and only the D-xylose tolerance test is routinely used. However D-xylose is a sugar that tests only the absorption of water-soluble compounds and it only tests duodenal absorption. In this study, we have evaluated carotenoids as markers of digestion and absorption. We compared fasting plasma carotenoids concentrations in 21 control subjects, 20 patients with Crohn's disease, and 18 patients with pancreatic cancer. Crohn's disease alters intestinal absorption while pancreatic cancer decreases pancreatic enzyme secretion thus impairing digestion. Results show that all carotenoids are significantly lower in Crohn's and cancer patients as compared to control subjects and the multifactorial analysis shows that this decrease is mostly independent of dietary intake. Interestingly, maldigestion as seen in pancreatic cancer more strongly influences plasma lutein and lycopene concentrations while malabsorption in Crohn's disease acts on other carotenoids. Thus carotenoids could be interesting alternatives for testing and following patients that are suspected of having malabsorption or maldigestion syndromes.

    Full Text Available This study compares heart rate variability (HRV and systolic blood pressure (SBP changes of spinal cord injury (SCI patients during urodynamic study (UDS with able-bodied controls.Twenty four complete suprasacral SCI patients (12 tetraplegia and 12 paraplegia and 12 age-matched able-bodied volunteers received BP and HRV evaluation throughout urodynamic examination. We chose seven time points during the examinations: resting, Foley catheter insertion, start of infusion, and infused volume reaching 1/4, 2/4, 3/4 and 4/4 of maximal capacity. At each time point, electrocardiogram with a duration of 5 min was used for power spectral density analysis of HRV.Only control subjects displayed significant elevation of SBP during Foley catheter insertion compared to resting values. Both control and tetraplegic groups experienced significant elevation of SBP at maximal bladder capacity compared to resting values. Tetraplegic values were also significantly greater than the other two groups. Control subjects displayed significant elevation of low frequency/high frequency (LF/HF ratios during Foley catheter insertion and when approaching maximum bladder capacity. These findings were not seen in the paraplegic and tetraplegic groups. However, subgroup analysis of tetraplegic subjects with SBP elevation >50 mmHg demonstrated a similar LF/HF response to the able-bodied controls.Tetraplegic patients experienced BP elevation but did not experience significant changes in HRV during bladder distension. This finding may imply that different neurological pathways contribute to AD reaction and HRV changes during bladder distension. However, profound AD during UDS in tetraplegic patients was associated with corresponding changes in HRV. Whether HRV monitoring would be beneficial in SCI patients presenting with significant AD, it needs further studies to elucidate.

Although knowledge about stroke warning signs and risk factors has received considerable attention, objective knowledge on secondary prevention and further self-esteem subjective knowledge have rarely been studied. The aim of our study was to investigate knowledge and treatment decisional role preferences in cerebrovascular patients compared to controls. Methods: We performed a survey on subjective and objective stroke risk knowledge and autonomy preferences in cerebrovascular patients from our stroke outpatient clinic (n=262 and from pedestrians on the street taken as controls during a “World Stroke Day” (n=274. The questionnaire includes measures for knowledge and decisional role preferences from previously published questionnaires and newly developed measures, for example, subjective knowledge, revealed on a visual analog scale. Results: The overall stroke knowledge was low to moderate, with no differences between patients and controls. Knowledge about secondary prevention was particularly low. Only 10%–15% of participants correctly estimated the stroke absolute risk reduction potential of aspirin. The medical data

    To evaluate differences in myocardial strain between pectus excavatum (PE) patients and healthy subjects (HS) assessed by cardiac MRI using the feature-tracking algorithm. Cardiac MRI was performed in 14 PE patients and 14 HS (9:5 male to female in each group; age 11-30 years) using a 3T scanner. Post-examination analysis included manual biventricular contouring with volumetry and ejection fraction measurement by two independent radiologists. Dedicated software was used for automated strain assessment. In five of the PE patients, the right ventricular ejection fraction was slightly impaired (40-44 %). PE patients had a significantly higher left ventricular longitudinal strain (P=0.004), mid (P=0.035) and apical (P=0.001) circumferential strain as well as apical circumferential strain rate (P=0.001), mid right ventricular circumferential strain (P=0.008) and strain rate (P=0.035), and apical right ventricular circumferential strain (P=0.012) and strain rate (P=0.044) than HS. The right ventricular longitudinal strain and strain rate did not differ significantly between PE patients and HS. Myocardial strain differs significantly between PE patients and HS. Higher myocardial strain in the mid and apical ventricles of PE patients indicates a compensation mechanism to enhance ventricular output against basal sternal compression. (orig.)

    Research of suicidal behavior in individuals with schizophrenia has often suggested that clinical characteristics and symptoms likely influence a patient's suicidal risk. However, there is a lack of research describing the link between patients' subjective quality of life (SQOL) and suicidal behavior in non-Western countries. Therefore, the current study attempts to explore how schizophrenia patients' SQOL and their suicidal behavior are related in a Taiwanese sample. In this study, 102 schizophrenia outpatients were investigated using the Taiwanese World Health Organization Quality of Life Schedule-Brief Version (WHO-QOL-BREF-TW), several Beck-Related symptom rating scales, and the Positive and Negative Syndrome Scale (PANSS) for psychopathology. These patients were also evaluated for suicidal risk using the critical items of the Scale for Suicide Ideation (SSI) and lifetime suicide attempts. Statistical analyses, including independent sample t tests, analysis of covariance (ANCOVA) and logistic stepwise regression models were completed. Compared with the non-suicidal group, suicidal patients had significantly lower scores in SQOL domains. The differences in social domain remained significant after adjusting for depressive symptoms. In multiple logistic regression analyses, level of depressive and psychotic symptoms increased and poor social and psychological SQOL were significant contributors to suicidal behavior. Having removed depressive symptoms from the model, only dissatisfaction with social SQOL was associated with heightened suicidal risk. Schizophrenia is associated with a high suicidal risk, of which depressive and psychotic symptoms are the major correlates. Again, the present study confirms and extends previous research showing that dissatisfied SQOL, particularly dissatisfaction with social relationships, should be considered in the assessment of suicidal risk in outpatients with schizophrenia, even when accounting other possible confounding factor

    To investigate the prevalence of malnutrition in patients with inflammatory bowel disease (IBD) by subjective global assessment (SGA) and the effects of oral nutritional support on the clinical parameters, consumption of energy, macronutrients and fiber intake in the Study and Control groups, prospectively. A total of 38 (28 Male; 10 Female) hospitalized patients with moderate or severe IBD (13 with Crohn's disease (CD); 25 with Ulcerative colitis (UC)) were included. At stage 1, the disease severity, clinical symptoms and, signs, food consumption and nutritional status by using subjective global assessment (SGA) were recorded. At stage 2, the patients were blindly randomized into a Study Group and Controls. In the Study Group, a standard enteral product was added into the regulated hospital diets, but for the Controls, deficits were regulated by only hospital diets for 3 weeks. the independent variables were the group, the disease and its activity, age, Body body mass index (BMI), weight loss history, the hospitalization period; the dependent variables were SGA, bowel movements, change in nutritional status, disease severity, clinical findings, and also consumption of macronutrients. Prevalance of malnutrition (SGA-B or SGA-C) for all the patients was 92.1% at the beginning and 71.1% at the end of study. Improvements in disease activity score for the patients with UC were statistically significant in both the Study Group and the Controls (p=0.006 for the Study Group and p=0.001 for the Controls, respectively). Macronutrients, total and water soluble fiber consumption levels improved, with statistically significant differences for all the groups. The prevalence of malnutrition is a major problem in patients with IBD. Not only the regulation of hospital food, but also enteral nutritional support, improved their levels of malnutrition, as well as their energy, macronutrients, and fiber consumption, and SGA is an easy method for nutritional monitoring.

    The study was performed to investigate the prevalence, awareness and the risk factors of chronic kidney disease (CKD) in the community population in Shanghai, China. A total of 2596 residents were randomly recruited from the community population in Shanghai, China. All were screened for albuminuria, haematuria, morning spot urine albumin-to-creatinine ratio and renal function. Serum creatinine, uric acid, cholesterol, triglyceride and haemoglobin were assessed. A simplified MDRD equation was used to estimate the glomerular filtration rate (eGFR). All studied subjects were screened by kidney ultrasound. Haematuria, if present in the morning spot urine dipstick test, was confirmed by microscopy. The associations among the demographic characteristics, health characteristics and indicators of kidney damage were examined. Two thousand five hundred and fifty-four residents (n = 2554), after giving informed consent and with complete data, were entered into this study. Albuminuria and haematuria were detected in 6.3% and 1.2% of all the studied subjects, respectively, whereas decreased kidney function was found in 5.8% of all studied subjects. Approximately 11.8% of subjects had at least one indicator of kidney damage. The rate of awareness of CKD was 8.2%. The logistic regression model showed that age, central obesity, hypertension, diabetes, anaemia, hyperuricaemia and nephrolithiasis each contributed to the development of CKD. This is the first Shanghai community-based epidemiological study data on Chinese CKD patients. The prevalence of CKD in the community population in Shanghai is 11.8%, and the rate of awareness of CKD is 8.2%. All the factors including age, central obesity, hypertension, diabetes, anaemia, hyperuricaemia and nephrolithiasis are positively correlated with the development of CKD in our studied subjects.

    Differences in health-related quality of life (HR-QoL) perception between alcohol abusing and non-substance-dependent subjects with liver cirrhosis could depend on differences in personality profile and influence management of patients awaiting liver transplant. We compared the perceptions of disease state in 78 male patients of similar disease severity divided into 2 groups based on etiology of cirrhosis: 47% had alcoholic cirrhosis, and 53% had hepatitis C virus(HCV)-related cirrhosis without alcohol abuse. Patients' perception of disease state was determined using the SAT-P questionnaire (a self-administered questionnaire that provides a global assessment of perceived HR-QoL and subjective well-being). The assessment yields 2 scales: an analytic scale based on 32 variables and a synthetic scale based on 5 factors. In patients with alcohol-related disease, ''psychological function'' was found to be more impaired,while ''sleep, diet, and free time'' was less impaired compared with subjects with HCV-related cirrhosis, suggesting dysfunction related to substance abuse with personality disturbance. The perception of disease state is different in alcohol-abusing patients with cirrhosis compared with those with cirrhosis unrelated to alcohol.

    The pharmacokinetics of orally administered mefloquine were determined in six healthy male subjects and in six ulcer patients before and after a 3-day course of cimetidine (400 mg morning and evening). Peak plasma concentrations Cmax and AUC0-infinity were similarly and significantly (P infinity was increased by 37.5% in healthy and peptic ulcer subjects respectively. The values of t1/2ab absorption and t1/2 beta elimination, total crearance CLT/F and volume of distribution were altered to varying levels after cimetidine treatment but the changes were not statistically significant in both healthy and peptic ulcer subjects. The established long t1/2 beta and this apparent interaction between mefloquine and cimetidine which resulted in increased mefloquine plasma concentration might be of clinical significant in patients with neurological/psychiatric history.

    The objective of this study was to determine how psychological characteristics, subjective symptoms, a family history of breast cancer, and age impact psychological distress in outpatients at the first hospital visit prior to breast cancer diagnosis. Participants were prediagnosed women with complaints of breast symptoms who either came to our hospital directly, or with a referral from another clinic. Patients were asked to complete questionnaires to determine the following: trait anxiety (State-Trait Anxiety Inventory), negative emotional suppression (Courtauld Emotional Control Scale), life stress events (Life Experiences Survey), and psychological distress (Profile of Mood States). We examined subjective symptoms (lumps, pain, abnormal nipple discharge, or deformed nipple) and family history of breast cancer based on answers to the interview sheet filled out by patients on their first visit. We analyzed a total of 154 patients who completed the questionnaires out of 237 eligible patients. A significant model was obtained by multiple regression analysis (adjusted R (2) = 0.574, p < 0.01) in which the standard partial regression coefficients for trait anxiety, suppression of anxiety, negative life change events, positive life change events, and subjective symptoms were statistically significant (beta = 0.623, 0.133, 0.155, 0.108, and 0.124, respectively; p < 0.05). Psychological distress prior to diagnosis was higher in patients who had high trait anxiety, suppression of anxiety, many life stress events, and subjective symptoms. In particular, trait anxiety had a large impact on psychological distress, underscoring the need for and importance of adequate psychological care.

    The objective of this study is to compare the gait variability of patients with lumbar spinal stenosis (experimental group) with healthy individuals (control group). The hypothesis is that the preoperative gait variability of the experimental group is higher than the control group. The experimental group consisted of 35 adults (18 males, 17 females). The subjects of the experimental group suffered exclusively from spinal stenosis. The patients were determined by MRI scans. A tri-axial accelerometer sensor was used for the gait measurement, and differential entropy algorithm was used to quantify the gait acceleration signal. The Oswestry Low Back Pain Questionnaire was used to determine the condition on the day of the measurement. Receiver operating characteristic (ROC) was utilized to assess the diagnostic value of the method and determine a cut-off value. There is a statistically significant difference between gait variability in the control group and the experimental group. ROC analysis determines a cut-off differential entropy value. The cut-off value has a 97.6% probability of separating patients with spinal stenosis from healthy subjects. The Oswestry Low Back Questionnaire is well correlated with the spectral differential entropy values

    To evaluate the test-retest reproducibility of a novel microperimeter with fundus image tracking (MP3, Nidek Co, Japan) in healthy subjects and patients with macular disease. Ten healthy subjects and 20 patients suffering from range of macular diseases were included. After training measurements, two additional microperimetry measurements were scheduled. Test-retest reproducibility was assessed for mean retinal sensitivity, pointwise sensitivity, and deep scotoma size using the coefficient of repeatability and Bland-Altman diagrams. In addition, in a subgroup of patients microperimetry was compared with conventional perimetry. Average differences in mean retinal sensitivity between the two study measurements were 0.26 ± 1.7 dB (median 0 dB; interquartile range [IQR] -1 to 1) for the healthy and 0.36 ± 2.5 dB (median 0 dB; IQR -1 to 2) for the macular patient group. Coefficients of repeatability for mean retinal sensitivity and pointwise retinal sensitivity were 1.2 and 3.3 dB for the healthy subjects and 1.6 and 5.0 dB for the macular disease patients, respectively. Absolute agreement in deep scotoma size between both study days was found in 79.9% of the test loci. The microperimeter MP3 shows an adequate test-retest reproducibility for mean retinal sensitivity, pointwise retinal sensitivity, and deep scotoma size in healthy subjects and patients suffering from macular disease. Furthermore, reproducibility of microperimetry is higher than conventional perimetry. Reproducibility is an important measure for each diagnostic device. Especially in a clinical setting high reproducibility set the basis to achieve reliable results using the specific device. Therefore, assessment of the reproducibility is of eminent importance to interpret the findings of future studies.

    While generic protocols exist for gait rehabilitation using robotic orthotics such as the Lokomat ® , several settings - guidance, body-weight support (BWS) and velocity - may be adjusted to individualize patient training. However, no systematic approach has yet emerged. Our objective was to assess the feasibility and effects of a systematic approach based on electromyography to determine subject-specific settings with application to the strengthening of the gluteus maximus muscle in post-stroke hemiparetic patients. Two male patients (61 and 65 years) with post-stroke hemiparesis performed up to 9 Lokomat ® trials by changing guidance and BWS while electromyography of the gluteus maximus was measured. For each subject, the settings that maximized gluteus maximus activity were used in 20 sessions of Lokomat ® training. Modified Functional Ambulation Classification (mFAC), 6-minutes walking test (6-MWT), and extensor strength were measured before and after training. The greatest gluteus maximus activity was observed at (Guidance: 70% -BWS: 20%) for Patient 1 and (Guidance: 80% - BWS: 30%) for Patient 2. In both patients, mFAC score increased from 4 to 7. The additional distance in 6-MWT increased beyond minimal clinically important difference (MCID=34.4m) reported for post-stroke patients. The isometric strength of hip extensors increased by 43 and 114%. Defining subject-specific settings for a Lokomat ® training was feasible and simple to implement. These two case reports suggest a benefit of this approach for muscle strengthening. It remains to demonstrate the superiority of such an approach for a wider population, compared to the use of a generic protocol. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Drug-free symptomatic panic patients, drug-treated nonsymptomatic patients and healthy controls were submitted to simulated public speaking. Subjective anxiety, cognitive impairment and discomfort measured by the visual analog mood scale as well as skin conductance level were higher in symptomatic patients than in controls at the beginning of the experimental session, nonsymptomatic patients lying in between. Subjective sedation, spontaneous fluctuations of skin conductance, heart rate and blood pressure were similar in the three groups. Preparation and performance of speech decreased sedation while increasing anxiety, cognitive impairment, level and fluctuations of skin conductance, heart rate and blood pressure. Anxiety, cognitive impairment and conductance level were less increased in symptomatic patients than in controls. Electrodermal activity, but not cardiovascular measures of sympathetic arousal correlated with anticipatory anxiety. Chronic treatment with serotonin uptake inhibitors attenuated the differences between panic patients and controls, supporting the participation of serotonin in panic disorder.

    The aims of the present study were to describe the short-term rate of subjective memory worsening (SMW) and identify factors of importance for SMW in a large clinical sample treated for depression with electroconvulsive therapy (ECT). This register-based study included 1212 patients from the Swedish National Quality Register for ECT. Subjective memory worsening was defined as a 2-point worsening on the memory item of the Comprehensive Psychopathological Rating Scale from before to within 1 week after treatment. Associations between patient characteristics and treatment factors were examined using logistic regression. Subjective memory worsening was experienced in 26%. It was more common in women than in men (31% vs 18%; P < 0.001) and more common in patients aged 18 to 39 years than in patients 65 years or older (32% vs 22%; P = 0.008). Patients with less subjective memory disturbances before ECT had a greater risk of SMW. Patients in remission after ECT had a lower risk of SMW. A brief pulse width stimulus gave higher risk of SMW compared with ultrabrief pulse (odds ratio, 1.61; 95% confidence interval, 1.05-2.47). Subjective memory worsening is reported by a minority of patients. However, young women are at risk of experiencing SMW. Ultrabrief pulse width stimulus could be considered for patients treated with unilateral electrode placement who experience SMW. Each patient should be monitored with regard to symptoms and adverse effects, and treatment should be adjusted on an individual basis to maximize the clinical effect and with efforts to minimize the cognitive adverse effects.

    Full Text Available Purpose. To evaluate and compare the subjective sensations reported by patients during first and second cataract extractions. Methods. Consecutive patients undergoing bilateral sequential cataract extraction using phacoemulsification were recruited. Following cataract surgery, patients completed questionnaires designed to evaluate subjective sensations, including anxiety, eye bulges, pain, and light sensitivity. Changes in painful sensations experienced by patients between the two surgeries were also recorded. Comparisons were also performed for each subjective sensation between different age groups (79 years. Results. A total of 127 patients were included in the final evaluation. Statistical comparison of the results showed that there were significant differences in perception of anxiety, eye bulges, and pain scores between the first and second cataract surgeries (P0.05 for all. Conclusions. Our research confirms the common observation that patients with bilateral cataracts often report more ocular discomfort during the second surgery. There are, therefore, additional factors that should be considered upon treating patients with bilateral cataracts, and the provision of preoperative counseling could play an important role in providing adequate patient care.

    Knowledge about culture- and migration-specific characteristics of subjective illness beliefs in Turkish patients is necessary for adequate treatment. Analysis of subjective illness beliefs in Turkish patients (F3; F4; n = 79) in comparison to matched Germans (n = 79) using a modified version of the Illness Perception Questionnaire IPQ-R. Differences were explored by t-tests and chi(2)-tests. Turkish patients believed significantly stronger in a chronical timeline of illness and in negative illness consequences, while German patients believed significantly stronger in treatment control and personal control. Turkish patients more often mentioned external causes of their disease compared to Germans. The results provide explanations of the deficient health care situation for Turkish migrants in Germany.

    To evaluate the extent of intra-subject difference in hamstring flexibility and its possible relationship to the severity of Low Back Pain (LBP). A secondary purpose was to evaluate the extent of intra-rater reliability using both electrogoniometer and conventional goniometer for measuring hamstring tightness. Potential correlations between muscle impairments and LBP may lead to more effective treatments and prevention strategies. Seventy two participants with mechanical LBP were recruited for this study. The sample included; 41 females, 31 males with a mean age of 33.69 ± (11.04) years, height of 170 ± (9) cm, and weight of 79.5 ± (1.6) kg. Hamstring length was detected indirectly using the Active Knee Extension method in the 90/90 position from supine. The amount of extension was measured using both electro-goniometer (EG)and a standard goniometer (SG). Right lower extremities of these patients were significantly more flexible than left ones at α = 0.025 (t_{72}= 3.14, p=0.002). Similarly, dominant lower extremities of these patients were significantly more flexible than the non dominant ones at α=0.025 (t _{72}=2.56, p=0.013). Additionally, Oswestry scores of the patients were significantly and positively correlated with the amount of hamstring tightness of the right lower extremities (r=0.244, p=0.039), left lower extremities (r=0.225, p=0.048) and the average of both sides (r=0.24, p=0.039). However, the Oswestry scores were negatively, but insignificantly correlated to the absolute difference between right and left extremities at (r=-0.156, p=0.091). Finally, the extent of intrasubject reliability in measuring hamstring tightness using EG and SG was found to be high (ICC=0.93).CONCLUSION: There is a possible relation between mild mechanical LBP and hamstrings tightness. It was found that the more the tightness, the higher the severity of LBP that patient experienced. Also, these patients had one of their lower extremities significantly tighter than the

    2018-01-01

    This study evaluated the psychometric properties of subjective sedation scales using one psychometric scoring system to identify the appropriate scale that is most suitable for clinical care practice. A number of published sedation assessment scales for paediatric patients are currently used to attempt to achieve a moderate depth of sedation to avoid the undesirable effects caused by over- or undersedation. However, there has been no systematic review of these scales. We searched the Cochrane Library, PubMed, EMBASE, the Cumulative Index to Nursing and Allied Health Literature, etc., to obtain relevant articles. The quality of the selected studies was evaluated according to the Consensus-based Standards for the Selection of Health Measurement Instruments checklist. Articles that had been published or were in press and discussed the psychometric properties of sedation scales were included. The population comprised critically ill infants and non-verbal children ranging in age from 0 to 18 years who underwent sedation in an intensive care unit. Data were independently extracted by two investigators using a standard data extraction checklist: 43 articles were included in this review, and 13 sedation scales were examined. The quality of the psychometric evidence for the Comfort Scale and Comfort Behaviour Scale was 'very good', with the Comfort Scale having a higher quality (total weighted scores, Comfort Scale = 17·3 and Comfort Behaviour Scale = 15·5). We suggest that the scales be systematically and comprehensively tested in terms of development method, reliability, validation, feasibility and correlation with clinical outcome. The Comfort Scale and Comfort Behaviour Scale are useful tools for measuring sedation in paediatric patients. Nursing staff should choose one subjective sedation scale that is suitable for assessing paediatric patients' depth of sedation. We recommend the Comfort Scale and Comfort Behaviour Scale as optimal choices if the clinical

    The aim of the present study was to explore and compare the caffeine intake, intoxication, withdrawal and dependence prevalence in Italian psychiatric patients and healthy subjects. Three hundred and sixty-nine out- and inpatients, suffering from different psychiatric disorders, and 104 healthy subjects were included in the study. They were assessed by the SCID and by a structured interview for caffeine intoxication and withdrawal and for substance dependence applied to caffeine use. Patients and healthy subjects did not differ in terms of current caffeine intake (mg/day, mean+/-SD: 281+/-325 vs. 288+/-148, respectively), while the maximum lifetime intake of caffeine was significantly higher in the first group (mg/day, mean SD: 630+/-549 vs. 504+/-344, respectively; F=4.897, p=.03) where it was significantly related to the CGI severity item scores (rho=.107; p=.04). In both patients and healthy subjects, a lower age was related to a higher current caffeine intake, while both current and maximum lifetime caffeine intake in the healthy subjects were significantly higher in men than in women. The patients suffering from eating disorders reported higher current caffeine intake than those with anxiety or mood disorders. The prevalence of dependence and intoxication was significantly higher in the patients than in the healthy subjects, without inter-group differences. Healthy subjects showed a trend towards a higher prevalence of withdrawal. Our study highlights the need that a more accurate attention should be paid to the caffeine use which seems to be strongly, although generically, related to different psychiatric disorders.

    Purpose To evaluate the test–retest reproducibility of a novel microperimeter with fundus image tracking (MP3, Nidek Co, Japan) in healthy subjects and patients with macular disease. Methods Ten healthy subjects and 20 patients suffering from range of macular diseases were included. After training measurements, two additional microperimetry measurements were scheduled. Test–retest reproducibility was assessed for mean retinal sensitivity, pointwise sensitivity, and deep scotoma size using the coefficient of repeatability and Bland-Altman diagrams. In addition, in a subgroup of patients microperimetry was compared with conventional perimetry. Results Average differences in mean retinal sensitivity between the two study measurements were 0.26 ± 1.7 dB (median 0 dB; interquartile range [IQR] −1 to 1) for the healthy and 0.36 ± 2.5 dB (median 0 dB; IQR −1 to 2) for the macular patient group. Coefficients of repeatability for mean retinal sensitivity and pointwise retinal sensitivity were 1.2 and 3.3 dB for the healthy subjects and 1.6 and 5.0 dB for the macular disease patients, respectively. Absolute agreement in deep scotoma size between both study days was found in 79.9% of the test loci. Conclusion The microperimeter MP3 shows an adequate test–retest reproducibility for mean retinal sensitivity, pointwise retinal sensitivity, and deep scotoma size in healthy subjects and patients suffering from macular disease. Furthermore, reproducibility of microperimetry is higher than conventional perimetry. Translational Relevance Reproducibility is an important measure for each diagnostic device. Especially in a clinical setting high reproducibility set the basis to achieve reliable results using the specific device. Therefore, assessment of the reproducibility is of eminent importance to interpret the findings of future studies. PMID:29430338

    Cefiderocol, a novel parenteral siderophore cephalosporin, exhibits potent efficacy against most Gram-negative bacteria, including carbapenem-resistant strains. The aim of this study was to perform a population pharmacokinetic (PK) analysis based on plasma cefiderocol concentrations in healthy subjects, subjects with various degrees of renal function, and patients with complicated urinary tract infection (cUTI) or acute uncomplicated pyelonephritis (AUP) caused by Gram-negative pathogens and to calculate the fraction of the time during the dosing interval where the free drug concentration in plasma exceeds the MIC ( fT MIC ). Population PK models were developed with three renal function markers, body surface area-adjusted estimated glomerular filtration rate (eGFR), absolute eGFR, and creatinine clearance, on the basis of 2,571 plasma concentrations from 91 subjects without infection and 238 patients with infection. The population PK models with each renal function marker adequately described the plasma cefiderocol concentrations. Clear relationships of total clearance (CL) to all renal function markers were observed. Body weight and disease status (with or without infection) were also significant covariates. The CL in patients with infection was 26% higher than that in subjects without infection. The fT MIC values were more than 75% in all patients (and were 100% in most patients), suggesting that a sufficient exposure to cefiderocol was provided by the tested dose regimens (2 g every 8 h as the standard dose regimen) for the treatment of cUTI or AUP caused by Gram-negative pathogens.

    There is a paucity of literature regarding the effects of thyroid disorders on the oral cavity by influencing the salivary gland function. This study aims to understand the qualitative and quantitative changes that thyroid disorder can cause in the salivary function. After obtaining ethical clearance, 46 consecutive newly diagnosed thyroid dysfunction patients were enrolled in this cross-sectional study, along with 45 age-and sex-matched controls. Unstimulated and stimulated salivary flow rates, pH, and buffering capacity of the whole saliva were studied in addition to subjective oral dryness in the study participants. The independent t-test was employed to compare the means between the two groups and Pearson's Chi-square test was used to assess the goodness of fit. The findings showed that females are more affected with thyroid disorders and that hypothyroidism is more commonly reported than hyperthyroidism. A significant reduction in the salivary flow rates and buffering capacity was observed among the affected group compared to the controls, whereas the salivary pH did not show significant differences between genders and also between the case and control groups. A feeling of subjective oral dryness was perceived by many affected patients. The study was able to establish an association between thyroid dysfunction and salivary gland function. We hope that this study leads to more high-impact research in this field as salivary diagnostics is gaining more popularity with every passing day.

    Compare survival in patients with multiple sclerosis (MS) from a U.S. commercial health insurance database with a matched cohort of non-MS subjects. 30,402 MS patients and 89,818 non-MS subjects (comparators) in the OptumInsight Research (OIR) database from 1996 to 2009 were included. An MS diagnosis required at least 3 consecutive months of database reporting, with two or more ICD-9 codes of 340 at least 30 days apart, or the combination of 1 ICD-9-340 code and at least 1 MS disease-modifying treatment (DMT) code. Comparators required the absence of ICD-9-340 and DMT codes throughout database reporting. Up to three comparators were matched to each patient for: age in the year of the first relevant code (index year - at least 3 months of reporting in that year were required); sex; region of residence in the index year. Deaths were ascertained from the National Death Index and the Social Security Administration Death Master File. Subjects not identified as deceased were assumed to be alive through the end of 2009. Annual mortality rates were 899/100,000 among MS patients and 446/100,000 among comparators. Standardized mortality ratios compared to the U.S. population were 1.70 and 0.80, respectively. Kaplan-Meier analysis yielded a median survival from birth that was 6 years lower among MS patients than among comparators. The results show, for the first time in a U.S. population, a survival disadvantage for contemporary MS patients compared to non-MS subjects from the same healthcare system. The 6-year decrement in lifespan parallels a recent report from British Columbia. Copyright © 2013 Elsevier B.V. All rights reserved.

    This study had two aims. The first was to assess and compare various types of aggressive behavior toward others reported by borderline patients and axis II comparison subjects over time. The second was to determine the best baseline and time-varying predictors of aggressive behavior in these borderline patients. At baseline, a series of interviews and self-report measures were administered to 290 borderline patients and 72 axis II comparison subjects. Measures assessing aggression toward others, axis I and II disorders as well as adult adversity were re-administered every two years over the course of ten years. It was found that borderline patients reported significantly higher rates of verbal, emotional, and physical aggression toward others than comparison subjects but the rates of these forms of aggression toward others declined significantly for those in both study groups. Multivariate analyses indicated that the strongest predictors of adult aggression towards others were severity of adult adversity and a substance use disorder. Taken together, these results suggest that borderline patients commonly report aggression toward others but that this aggression declines significantly over time. These results also suggest that this aggression toward others is most strongly associated with adult experiences of adversity and concurrent substance abuse. Copyright © 2017 Elsevier Ireland Ltd.

    We assessed the efficacy and safety of extended-release gabapentin in a 15-week, open-label, single-arm, single-center study in patients with fibromyalgia (FM). Subjects with documented diagnosis of FM were allowed to participate in the study. We opened enrollment to those who have tried and failed gabapentinoids such as gabapentin or pregabalin due to side effects. Subjects with autoimmune conditions, and or taking opioids for management of their FM pain, were excluded from the study. Subjects were given an extended-release gabapentin starter pack and treated for total of 12 weeks. The primary study endpoint of pain relief was measured using Numeric Pain Rating System (NPRS) scores, and secondary study endpoints were measured with Fibromyalgia Impact Questionnaire (FIQ), Patient's Global Impression of Change (PGIC), and Medical Outcome Sleep questionnaires (MOS). A total of 34 subjects were enrolled and 29 subjects completed the starter pack (85%). Patients reported significant pain relief on NPRS by end of 4 weeks (P life by end of 4 weeks on FIQ (P quality. Improvements in primary and secondary measurements were reflected in PGIC, with significant improvement in patient's impression of FM by week 8. Small sample size, geographical bias, relatively short duration of treatment, and single-arm study without control group. Extended-release gabapentin relieved FM pain symptoms and improved quality-of-life for the FM subjects studied. Subjects reported improvements in both quantity and quality of sleep. © 2015 World Institute of Pain.

    BACKGROUND: Data indicate that the levels of serum homocysteine in depressive patients are higher than those in normal subjects. OBJECTIVE: To investigate the levels of serum homocysteine in patients with major depressive disorder, to determine whether serum homocysteine levels differ with sex, family history, or drug treatment, and to compare depressive patients with normal subjects. DESIGN: Non-randomized concurrent control trial.SETTING: Mental Heath Center of Shandong Province.PARTICIPANTS: Forty in-patients (23 males and 17 females, 18-63 years old) with major depressive disorder were selected from the Mental Health Center of Shandong Province from January to October 2006. All selected patients met the depressive diagnostic standard of Chinese Classification of Mental Disorder (3rd Edition, CCMD-3), and total scores evaluated by the 17-item Hamilton Rating Scale for Depression (HRSD) were ≥ 20. Meanwhile, 36 healthy subjects (20 males and 16 females, 18-60 years old) were enrolled as controls; their total 17-item HRSD scores were ≤ 7. All selected subjects provided consent, and the study was approved by the local ethics committee. METHODS: Fasting venous blood (3 mL) was drawn in both groups at 8:00 in the morning. The levels of serum homocysteine were determined by a fluorescence polarization immunoassay (FPIA). The 17-item HRSD was also compiled from the patients when entering groups. The higher the scores were, the more severe the depression was. Enumeration data for both groups were compared by Chi-square test, measurement data were compared by t-test, and correlations were detected using Pearson and Spearman correlation analysis.MAIN OUTCOME MEASURES: ① Levels of serum homocysteine; ② incidence of hyperhomocysteinemia (Hhcy); ③ correlation between HRSD17 scores and levels of serum homocysteine in depressive patients.RESULTS: Forty depressive patients and 36 control subjects were included in the final analysis without any loss of participants.

    Many studies highlight that an impaired ability to communicate is one of the key clinical features of Alzheimer disease (AD). To study temporal organisation of speech in an oral reading task in patients with AD and in matched healthy controls using a semi-automatic method, and evaluate that method's ability to discriminate between the 2 groups. A test with an oral reading task was administered to 70 subjects, comprising 35 AD patients and 35 controls. Before speech samples were recorded, participants completed a battery of neuropsychological tests. There were no differences between groups with regard to age, sex, or educational level. All of the study variables showed impairment in the AD group. According to the results, AD patients' oral reading was marked by reduced speech and articulation rates, low effectiveness of phonation time, and increases in the number and proportion of pauses. Signal processing algorithms applied to reading fluency recordings were shown to be capable of differentiating between AD patients and controls with an accuracy of 80% (specificity 74.2%, sensitivity 77.1%) based on speech rate. Analysis of oral reading fluency may be useful as a tool for the objective study and quantification of speech deficits in AD. Copyright © 2012 Sociedad Española de Neurología.

    Highlights: • Heart deformation analysis (HDA) can quantify global and regional cardiac function. • HDA works based on cine CMR images without the needs of operator interaction. • HDA-derived cardiac motion indices are reproducible. - Abstract: Objective: To test the performance of HDA in characterizing left ventricular (LV) function and regional myocardial motion patterns in the context of cardiomyopathy based on cine cardiovascular magnetic resonance (CMR). Materials and methods: Following the approval of the institutional review board (IRB), standard cine images of 45 subjects, including 15 healthy volunteers, 15 patients with hypertrophic cardiomyopathy (HCM) and 15 patients with dilated cardiomyopathy (DCM) were retrospectively analyzed using HDA. The variations of LV ejection fraction (LVEF), LV mass (LVM), and regional myocardial motion indices, including radial (Drr), circumferential (Dcc) displacement, radial (Vrr) and circumferential (Vcc) velocity, radial (Err), circumferential (Ecc) and shear (Ess) strain and radial (SRr) and circumferential (SRc) strain rate, were calculated and compared among subject groups. Inter-study reproducibility of HDA-derived myocardial motion indices were tested on 15 volunteers by using intra-class correlation coefficient (ICC) and coefficient of variation (CoV). Results: HDA identified significant differences in cardiac function and motion indices between subject groups. DCM patients had significantly lower LVEF (33.5 ± 9.65%), LVM (105.88 ± 21.93 g), peak Drr (0.29 ± 0.11 cm), Vrr-sys (2.14 ± 0.72 cm/s), Err (0.17 ± 0.08), Ecc (−0.08 ± 0.03), SRr-sys (0.91 ± 0.44s{sup −1}) and SRc-sys (−0.64 ± 0.27s{sup −1}) compared to the other two groups. HCM patients demonstrated increased LVM (171.69 ± 34.19) and lower peak Vcc-dia (0.78 ± 0.30 cm/s) than other subjects. Good inter-study reproducibility was found for all HDA-derived myocardial indices in healthy volunteers (ICC = 0.664–0.942, CoV = 15.1%–37

    This study examined the burden on family members of patients with schizophrenia in a Chilean community. Sixty-five caregivers underwent the Subjective and Objective Family Burden Interview. The results showed moderate to high levels of subjective burden and low levels of support from others in providing care. Burden and containment of disturbed behaviour were correlated with worse relationships between patients and caregivers, with the latter spending less time working outside the home. The assessed sample showed a similar pattern of burden to that of caregivers from developed countries; however, the extent of the burden tended to be higher in Chilean caregivers.

    The regulatory mechanism of the pituitary-thyroid axis in normal subjects and patients with Graves' disease was investigated using a highly sensitive TSH assay based on the immunoradiometric assay. All of the normal subjects had detectable TSH values within the range 0.35 to 6.0 μU/ml. No negative correlations between TSH and free thyroid hormones existed in normal subjects. Patients with thyroid carcinoma who seemed to have normal pituitary-thyroid function showed a rapid increase of TSH after total thyroidectomy. On the other hand, while untreated patients with Graves' disease all had undetectable TSH values, these patients took 1 to 3.5 months longer to normalize their TSH values than to normalize free thyroid hormones on antithyroid drug therapy. During the recovery phase by the treatment with decrease of antithyroid drug or supplement of T 4 from iatrogenic hypothyroid state after treatment for Graves' disease and thyroid carcinoma, normalization of TSH levels was delayed than that of free thyroid hormones. Patients with Graves' disease in remission showed an extremely positive correlation between basal and peak TSH levels in TRH test, and a negative correlation between basal TSH and FT 4 . In conclusion, an individual patient may have a different set point concerning the regulatory mechanism of the pituitary-thyroid axis, and the persistence of the hyperthyroid state would seem to have caused some reversible dysfunction of the pituitary gland.

    The aim of this study is to measure the on- and off-responses and their response asymmetries elicited by sawtooth stimuli in normal subjects and glaucoma patients. Furthermore, the correlation between the ERGs and other functional and structural parameters are investigated. Full-field stimuli were produced using a Ganzfeld bowl with Light Emitting Diodes (LEDs) as light sources. On- and off-response ERGs were recorded from 17 healthy subjects, 12 pre-perimetric and 15 perimetric glaucoma patients using 4-Hz luminance rapid-on and rapid-off sawtooth stimuli (white light; mean luminance 55 cd/m(2)) at 100% contrast. The on- and off-responses were added to study response asymmetries. In addition, flash ERGs were elicited by red stimuli (200 cd/m(2)) on a blue background (10 cd/m(2)). The mean deviations (MD) of the visual field defects were obtained by standard automated perimetry. The retinal nerve fibre layer thickness (RNFLT) was measured with Spectral Domain Optical Coherence Tomography (SOCT). We studied the correlation between ERG response amplitudes, visual field mean deviation (MDs) and RNFLT values. The on-responses showed an initial negative (N-on) followed by a positive (P-on), a late positive (LP-on) and a late negative responses (LN-on). The off-responses showed an initial positive (P-off) a late positive (LP-off) and a late negative response (LN-off). The addition of on- and off-responses revealed an initial positive (P-add) and a late negative response (LN-add). The on-response components (N-on, P-on and LN-on) in the glaucoma patients were relatively similar to those of the control subjects. However, the LP-on was significantly elevated (p = 0.03) in perimetric patients. The LP-off was significantly elevated (p < 0.001), and the amplitude of LN-off was significantly reduced in perimetric patients (p = 0.02). The LN-add amplitude was significantly reduced (p < 0.001) and delayed (p = 0.03) in perimetric patients. The amplitudes of the LN-off and LN

    The study gathered information on how users search the database of the International Nuclear Information System (INIS), using indicators such as Subject categories, Controlled terms, Subject headings, Free-text words, combinations of the above. Users participated from the Australian, French, Russian and Spanish INIS Centres, that have different national languages. Participants, both intermediaries and end users, replied to a questionnaire and executed search queries. The INIS Secretariat at the IAEA also participated. A protocol of all search strategies used in actual searches in the database was kept. The thought process for Russian and Spanish users is predominantly non-English and also the actual initial search formulation is predominantly non-English among Russian and Spanish users while it tends to be more in English among French users. A total of 1002 searches were executed by the five INIS centres including the IAEA. The search protocols indicate the following search behaviour: 1) free text words represent about 40% of search points on an average query; 2) descriptors used as search keys have the widest range as percentage of search points, from a low of 25% to a high of 48%; 3) search keys consisting of free text that coincides with a descriptor account for about 15% of search points; 4) Subject Categories are not used in many searches; 5) free text words are present as search points in about 80% of all searches; 6) controlled terms (descriptors) are used very extensively and appear in about 90% of all searches; 7) Subject Headings were used in only a few percent of searches. From the results of the study one can conclude that there is a greater reluctance on the part of non-native English speakers in initiating their searches by using free text word searches. Also: Subject Categories are little used in searching the database; both free text terms and controlled terms are the predominant types of search keys used, whereby the controlled terms are used more

    Full Text Available Fibromyalgia is a chronic widespread pain syndrome associated with chronic fatigue. Its pathogenesis is not clearly understood. This study presents subjective experiences and sensitivities reported by fibromyalgia patients, which should be considered in primary care to avoid medical nomadism, as well as stigmatization of the patients. The prevalence of significant characteristics was compared with others patients consulting at the same pain unit who suffer from rebel and disabling form of chronic migraine. Psychometric tests were anonymously completed by 78 patients of the Pain Unit (44 fibromyalgia patients and 34 migraine patients. Tests evaluated pain (Visual Analog scale, childhood traumas (Childhood Trauma Questionnaire, lack of parental affection, stressful life events (Holmes and Rahe Scale, anxiety and depression (Hospital Anxiety and Depression Scale, perceived hypersensitivity to 10 stimuli, and hyperactivity before illness. However, pain scores were comparable in the two groups, and the prevalence was significantly higher in fibromyalgia patients than in migraine patients for anxiety (81.8% versus 51.5% and depression (57.1% versus 8.8%. Childhood physical abuses were more frequently reported in fibromyalgia than in migraine cases (25% versus 3%. Similarly, the feeling of lack of parental affection, subjective hypersensitivity to stress and stimuli (cold, moisture, heat, full moon, and flavors or hyperactivity (ergomania, appeared as prominent features of fibromyalgia patients. Fibromyalgia patients considered themselves as being hypersensitive (mentally and physically compared to migraine patients. They also have higher depression levels. Beyond somatic symptoms, precociously taking account of psychosocial and behavioral strategies would highly improve treatment efficiency of the fibromyalgia syndrome.

    A noninvasive scintigraphic technique was used to estimate enterogastric reflux and subsequent gastric evacuation of refluxate in 35 normal, healthy subjects and 55 patients previously treated by vagotomy or partial gastrectomy. Reflux was provoked by a milk drink and quantitated by counting 99Tcm-EHIDA activity within the gastric area during gamma camera imaging. Seven normal subjects (20%) showed reflux of 5-18% of initial activity (mean: 10%), with peak values occurring at 5-30 minutes (mean: 14 minutes) following the milk. Gastric evacuation of activity in these subjects was monoexponential (r = 0.993, T1/2 = 24.1 minutes). Reflux occurred more frequently than normal in patients with truncal vagotomy and drainage (22/28 patients) and partial gastrectomy (20/21 patients). All of 16 patients with Billroth II anastomoses exhibited reflux, which was excessive compared with refluxing normal subjects (mean: 25%; p less than 0.01) and occurred later into the study (mean: 34 minutes; p less than 0.01). Ten of 11 asymptomatic patients showed reflux of similar amounts of activity (mean: 21%) compared with 16 patients who complained of bile vomiting (mean: 22%). However, asymptomatic patients exhibited gastric evacuation of refluxate at a rate similar to that of refluxing normal subjects, while bile vomiters showed significant gastric retention of refluxate at 25-30 minutes following peak gastric activity (p less than 0.05). This result confirms that post-operative bile vomiting is essentially a problem of gastric emptying

    Haptic control is a useful therapeutic option in rehabilitation featuring virtual reality interaction. As with visual and vibrotactile biofeedback, kinesthetic haptic feedback may assist in postural control, and can achieve balance control. Kinesthetic haptic feedback in terms of body sway can be delivered via a commercially available haptic device and can enhance the balance stability of both young healthy subjects and stroke patients. Our system features a waist-attached smartphone, software running on a computer (PC), and a dedicated Phantom Omni® device. Young healthy participants performed balance tasks after assumption of each of four distinct postures for 30 s (one foot on the ground; the Tandem Romberg stance; one foot on foam; and the Tandem Romberg stance on foam) with eyes closed. Patient eyes were not closed and assumption of the Romberg stance (only) was tested during a balance task 25 s in duration. An Android application running continuously on the smartphone sent mediolateral (ML) and anteroposterior (AP) tilt angles to a PC, which generated kinesthetic haptic feedback via Phantom Omni®. A total of 16 subjects, 8 of whom were young healthy and 8 of whom had suffered stroke, participated in the study. Post-experiment data analysis was performed using MATLAB®. Mean Velocity Displacement (MVD), Planar Deviation (PD), Mediolateral Trajectory (MLT) and Anteroposterior Trajectory (APT) parameters were analyzed to measure reduction in body sway. Our kinesthetic haptic feedback system was effective to reduce postural sway in young healthy subjects regardless of posture and the condition of the substrate (the ground) and to improve MVD and PD in stroke patients who assumed the Romberg stance. Analysis of Variance (ANOVA) revealed that kinesthetic haptic feedback significantly reduced body sway in both categories of subjects. Kinesthetic haptic feedback can be implemented using a commercial haptic device and a smartphone. Intuitive balance cues were

    Previous studies suggest central nervous system involvement in chronic fatigue syndrome (CFS), yet there are no established diagnostic criteria. CFS may be difficult to differentiate from clinical depression. The study's objective was to determine if spectral coherence, a computational derivative of spectral analysis of the electroencephalogram (EEG), could distinguish patients with CFS from healthy control subjects and not erroneously classify depressed patients as having CFS. This is a study, conducted in an academic medical center electroencephalography laboratory, of 632 subjects: 390 healthy normal controls, 70 patients with carefully defined CFS, 24 with major depression, and 148 with general fatigue. Aside from fatigue, all patients were medically healthy by history and examination. EEGs were obtained and spectral coherences calculated after extensive artifact removal. Principal Components Analysis identified coherence factors and corresponding factor loading patterns. Discriminant analysis determined whether spectral coherence factors could reliably discriminate CFS patients from healthy control subjects without misclassifying depression as CFS. Analysis of EEG coherence data from a large sample (n = 632) of patients and healthy controls identified 40 factors explaining 55.6% total variance. Factors showed highly significant group differentiation (p EEG spectral coherence analysis identified unmedicated patients with CFS and healthy control subjects without misclassifying depressed patients as CFS, providing evidence that CFS patients demonstrate brain physiology that is not observed in healthy normals or patients with major depression. Studies of new CFS patients and comparison groups are required to determine the possible clinical utility of this test. The results concur with other studies finding neurological abnormalities in CFS, and implicate temporal lobe involvement in CFS pathophysiology.

    A high-resolution two-dimensional electrophoretic method for protein, with silver staining, has been used to characterize and identify urinary high-density-lipoprotein apolipoproteins (HDL-Apos) and their isoforms in healthy subjects and in patients with kidney disease. Analytical techniques based on both molecular mass and ultracentrifugal flotation properties were used to isolate urinary lipoprotein particles with characteristics identical to those of HDL in plasma. HDL-Apos identified in urine of normal subjects and patients with glomerular proteinuria were Apos A-I, A-II, and C. Five isoforms of Apo A-I were present. Immunostaining of electroblotted proteins further confirmed the presence of HDL-Apos in urine. Creatinine clearance rate was decreased in the patients with proteinuria, and ranged from 32.5 to 40 mL/min. Concentrations of cholesterol and triglycerides in serum were greater in the patients' group, whereas mean HDL-cholesterol (0.68, SD 0.10 mmol/L) and Apo A-I (0.953, SD 0.095 g/L) were significantly (each P less than 0.01) lower. Results of this study suggest that measurement of urinary Apo A-I will reflect excretion of HDL in urine.

    AV-45 amyloid biomarker is known to show uptake in white matter in patients with Alzheimer's disease (AD), but also in the healthy population. This binding, thought to be of a non-specific lipophilic nature, has not yet been investigated. The aim of this study was to determine the differential pattern of AV-45 binding in white matter in healthy and pathological populations. We recruited 24 patients presenting with AD at an early stage and 17 matched, healthy subjects. We used an optimized positron emission tomography-magnetic resonance imaging (PET-MRI) registration method and an approach based on an intensity histogram using several indices. We compared the results of the intensity histogram analyses with a more canonical approach based on target-to-cerebellum Standard Uptake Value (SUVr) in white and grey matter using MANOVA and discriminant analyses. A cluster analysis on white and grey matter histograms was also performed. White matter histogram analysis revealed significant differences between AD and healthy subjects, which were not revealed by SUVr analysis. However, white matter histograms were not decisive to discriminate groups, and indices based on grey matter only showed better discriminative power than SUVr. The cluster analysis divided our sample into two clusters, showing different uptakes in grey, but also in white matter. These results demonstrate that AV-45 binding in white matter conveys subtle information not detectable using the SUVr approach. Although it is not more efficient than standard SUVr in discriminating AD patients from healthy subjects, this information could reveal white matter modifications. (orig.)

  18. The Utility of the Wisconsin Card Sorting Test in Differential Diagnosis of Cognitive Disorders in Iranian Psychiatric Patients and Healthy Subjects

    Full Text Available Objective: The Wisconsin Test Card Sorting Test (WCST is a neuropsychological test that has been suggested as a more specific test for frontal lobes dysfunctions. This study was designed to determine whether WCST is able to differentiate between Iranian psychiatric patients with cognitive disorders and normal subjects, and whether WCST scores are related to severity of symptoms in depressive and schizophrenic patients.Method: Participants were four groups: schizophrenics with positive symptoms (n=25; schizophrenics with negative symptoms (n=25; major depressives (n=25; and normal subjects (n=25. All subjects were tested individually using WCST. To analyze the data, various descriptive statistics, ANOVA, t-test and multiple regression analysis were used.Results: Regarding the number of categories (P<0.001 and the rate of perseverative errors (P<0.01, according to the results, the normal subjects performed significantly better than patient groups on WCST, although the differences between patient groups were not significant. Our results also showed that greater positive or depressive symptoms were not associated with poorer scores on WCST performance. Only the level of severity of negative symptoms predicted scores on perseverative errors.Conclusion: It is concluded that WCST can differentiate Iranian psychiatric patients with cognitive disorders from normal subjects, but it is not able to clearly differentiate schizophrenic patients with negative symptoms from those with positive symptoms and depressives. Only severity of negative symptoms affects WCST performance

    Describing the morphologic features of the thoracic pedicle in patients with adolescent idiopathic scoliosis is necessary for placement of pedicle screws. Previous studies showed inadequate reliability owing to small sample size and heterogeneity of the patients surveyed. To use CT scans (1) to describe the morphologic features of 2718 thoracic pedicles from 60 female patients with Lenke Type 1 adolescent idiopathic scoliosis and 60 age-, sex-, and height-matched controls; and (2) to classify the pedicles in three types based on pedicle width and analyze the distribution of each type. A total of 2718 pedicles from 60 female patients with Lenke Type 1 adolescent idiopathic scoliosis and 60 matched female controls were analyzed via CT. All patients surveyed were diagnosed with adolescent idiopathic scoliosis, Lenke Type 1, at the First Affiliated Hospital of Sun Yat-sen University, and all underwent pedicle screw fixation between January 2008 and December 2013 with preoperative radiographs and CT images on file. We routinely obtained CT scans before these procedures; all patients who underwent surgery during that period had CT scans, and all were available for analysis here. Control subjects had CT scans for other clinical indications and had no abnormal findings of the spine. The control subjects were chosen to match patients in terms of age (15 ± 2.6 years versus 15 ± 2.6 years) and sex. Height of the two groups also was matched (154 ± 9 cm versus 155 ± 10 cm; mean difference, -1.06 cm; 95% CI, -1.24 to -0.81 cm; p adolescent idiopathic scoliosis (22%; 293 of 1322) compared with controls (13%; 178 of 1396) (odds ratio [OR] = 0.51; 95% CI, 0.42-0.63; p adolescent idiopathic scoliosis, they commonly occurred on the concave side 34% (228 of 661) and on the AV-SC region (32%; 43 of 136). Pedicle width on the concave side was narrower than pedicle width on the convex side and pedicle width in healthy control subjects. The apical vertebra in the structural curve was

    Cognitive complaints occur frequently in elderly people and may be a risk factor for dementia and cognitive decline. Results from studies on subjective cognitive decline are difficult to compare due to variability in assessment methods, and little is known about how different methods influence reports of cognitive decline. The Subjective Memory Complaints Scale (SMC) and The Memory Complaint Questionnaire (MAC-Q) were applied in 121 mixed memory clinic patients with mild cognitive symptoms (mean MMSE = 26.8, SD 2.7). The scales were applied independently and raters were blinded to results from the other scale. Scales were not used for diagnostic classification. Cognitive performances and depressive symptoms were also rated. We studied the association between the two measures and investigated the scales' relation to depressive symptoms, age, and cognitive status. SMC and MAC-Q were significantly associated (r = 0.44, N = 121, p = 0.015) and both scales had a wide range of scores. In this mixed cohort of patients, younger age was associated with higher SMC scores. There were no significant correlations between cognitive test performances and scales measuring subjective decline. Depression scores were significantly correlated to both scales measuring subjective decline. Linear regression models showed that age did not have a significant contribution to the variance in subjective memory beyond that of depressive symptoms. Measures for subjective cognitive decline are not interchangeable when used in memory clinics and the application of different scales in previous studies is an important factor as to why studies show variability in the association between subjective cognitive decline and background data and/or clinical results. Careful consideration should be taken as to which questions are relevant and have validity when operationalizing subjective cognitive decline.

    To evaluate nutritional status in adult patients with acute leukemia (AL) using patient-generated subjective global assessment (PG-SGA) and to investigate the influence of nutritional status on prognosis.We observationally investigated 68 adult patients with newly diagnosed AL who received PG-SGA at the First Hospital of Jilin University between May 2013 and July 2015. Clinical features, chemotherapy regimens, biochemical indexes, body composition, complete remission (CR) rate, minimal residual disease (MRD), survival time, and side-effects of chemotherapy were compared between patients with and without severe malnutrition.Mean PG-SGA scores of the total patients were 6.1 ± 4.0, and 19 of 68 (27.9%) patients had severe malnutrition (PG-SGA score ≥9). Patients with acute myeloid leukemia (AML) had higher scores than those with acute lymphocytic leukemia (ALL; P = .011) and high-risk patients had higher scores regardless of whether they had AML or ALL (AML, P = .012; ALL, P = .043). Univariate analysis showed that severe malnutrition was correlated with age (P = .041), transferrin (P = .042), Karnofsky Performance Status score (P = .006), and C-reactive protein (CRP) (P = .018). Multivariate analysis demonstrated that severe malnutrition was associated with CRP (hazard ratio [HR] = 1.020, 95% confidence interval [CI]: 1.002-1.039, P = .026). No difference was found in CR rate (P = .831) between patients with and without malnutrition, but those who were severely malnourished had higher MRD (P = .048 in AML patients, P = .036 in ALL patients) and more gastrointestinal side-effects (P = .014). Severe malnutrition was also associated with inferior overall survival (HR = 0.243, 95% CI: 0.063-0.945, P = .041) but not with event-free survival (HR = 0.808, 95% CI: 0.338-1.934, P = .663).Severe malnutrition defined by PG-SGA in adult patients with de novo AL may result in poor outcome.

    To investigate the relationship between sedation and the memories reported by patients subjected to mechanical ventilation following discharge from the intensive care unit. This prospective, observational, cohort study was conducted with individuals subjected to mechanical ventilation who remained in the intensive care unit for more than 24 hours. Clinical statistics and sedation records were extracted from the participants' clinical records; the data relative to the participants' memories were collected using a specific validated instrument. Assessment was performed three months after discharge from the intensive care unit. A total of 128 individuals were assessed, most of whom (84.4%) reported recollections from their stay in the intensive care unit as predominantly a combination of real and illusory events. The participants subjected to sedation (67.2%) at deep levels (Richmond Agitation-Sedation Scale [RASS] -4 and -5) for more than two days and those with psychomotor agitation (33.6%) exhibited greater susceptibility to occurrence of illusory memories (p>0.001). The probability of the occurrence of illusory memories was greater among the participants who were subjected to deep sedation. Sedation seems to be an additional factor that contributed to the occurrence of illusory memories in severely ill individuals subjected to mechanical ventilation.

    This work assessed both subjective and objective postoperative parameters after breast reduction surgery and compared between patients and plastic surgeons. After an average postoperative observation period of 6.7 ± 2.7 (2 - 13) years, 159 out of 259 patients (61 %) were examined. The mean age at the time of surgery was 37 ± 14 (15 - 74) years. The postoperative anatomy of the breast and other anthropometric parameters were measured in cm with the patient in an upright position. The visual analogue scale (VAS) values for symmetry, size, shape, type of scar and overall satisfaction both from the patient's and from four plastic surgeons' perspectives were assessed and compared. Patients rated the postoperative result significantly better than surgeons. Good subjective ratings by patients for shape, symmetry and sensitivity correlated with high scores for overall assessment. Shape had the strongest influence on overall satisfaction (regression coefficient 0.357; p reduction surgery, long-term outcome is rated significantly better by patients than by plastic surgeons. Good subjective ratings by patients for shape, symmetry and sensitivity correlated with high scores for overall assessment. Shape had the strongest influence on overall satisfaction, followed by symmetry and sensitivity of the breast. Postoperative size of the breast, resection weight, type of scar, age or BMI was not of significant influence. Symmetry was the only assessed subjective parameter of this study that could be objectified by postoperative measurements. Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Coronary artery disease (CAD is the most common cause of death globally. To detect CAD noninvasively at an early stage before clinical symptoms occur is still nowadays challenging. Analysis of the variation of heartbeat interval (RRI opens a new avenue for evaluating the functional change of cardiovascular system which is accepted to occur at the subclinical stage of CAD. In addition, systolic time interval (STI and diastolic time interval (DTI also show potential. There may be coupling in these electromechanical time series due to their physiological connection. However, to the best of our knowledge no publication has systematically investigated how can the coupling be measured and how it changes in CAD patients. In this study, we enrolled 39 CAD patients and 36 healthy subjects and for each subject the electrocardiogram (ECG and photoplethysmography (PPG signals were recorded simultaneously for 5 min. The RRI series, STI series, and DTI series were constructed, respectively. We used linear cross correlation (CC, coherence function (CF, as well as nonlinear mutual information (MI, cross conditional entropy (XCE, cross sample entropy (XSampEn, and cross fuzzy entropy (XFuzzyEn to analyse the bivariate RRI-DTI coupling, RRI-STI coupling, and STI-DTI coupling, respectively. Our results suggest that the linear CC and CF generally have no significant difference between the two groups for all three types of bivariate coupling. The MI only shows weak change in RRI-DTI coupling. By comparison, the three entropy-based coupling measurements show significantly decreased coupling in CAD patients except XSampEn for RRI-DTI coupling (less significant and XCE for STI-DTI and RRI-STI coupling (not significant. Additionally, the XFuzzyEn performs best as it was still significant if we further applied the Bonferroni correction in our statistical analysis. Our study indicates that the intrinsic electromechanical coupling is most probably nonlinear and can better

    influence reports of cognitive decline. METHODS: The Subjective Memory Complaints Scale (SMC) and The Memory Complaint Questionnaire (MAC-Q) were applied in 121 mixed memory clinic patients with mild cognitive symptoms (mean MMSE = 26.8, SD 2.7). The scales were applied independently and raters were blinded...... decline. Depression scores were significantly correlated to both scales measuring subjective decline. Linear regression models showed that age did not have a significant contribution to the variance in subjective memory beyond that of depressive symptoms. CONCLUSIONS: Measures for subjective cognitive...... decline are not interchangeable when used in memory clinics and the application of different scales in previous studies is an important factor as to why studies show variability in the association between subjective cognitive decline and background data and/or clinical results.

    Full Text Available Background: Diabetes mellitus is a common chronic metabolic disease which have numerous physical effects for patients. Objective: The aim of this study was to determine the prevalence of subjective xerostomia and burning mouth of patients with type 2 diabetes mellitus in cities of Sari and Qaemshahr. Methods: In this descriptive-analytic study, totally 1455 patients with type 2 diabetes mellitus with complain of xerostomia and/or burning mouth which had referred to diabetes clinic in Sari and Qaemshahr were examined in 2016. For every patient asked about chronic xerostomia and burning mouth and if the answer was positive, the oral examination was done to ensure the absence of mucosal lesions and find signs of xerostomia. Then, xerostomia questionnaire was completed by patients suffering from dry mouth. Finally, the information was statistically analyzed by T test and chi square test. Findings: Prevalence of burning mouth was found 111 (7.6% in diabetic patients that in the women were significantly higher than in men (P<0.0001. Prevalence of xerstomia patients was found 239 (16.4% that was not significant between the male and female. There was a significant correlation between burning mouth and xerostomia with FBS and HbA1c in diabetic patients (P<0.0001. Conclusion: Possibility of burning mouth, and xerostomia will increase in the diabetic patients with low metabolic control which can cause more severe side effects related to oral health.

    To assess the impact of autologous serum (AS) eye drops on the ocular surface of patients with bilateral severe dry eye and to draw a comparison between the clinical and laboratory examinations and the degree of subjective symptoms before and after serum treatment. A three-month prospective study was conducted on 17 patients with severe dry eye. AS eye drops were applied a maximum of 12 times a day together with regular therapy. Dry eye status was evaluated by clinical examination (visual acuity, Schirmer test, tear film breakup time, vital staining, tear film debris and meniscus), conjunctival impression cytology (epithelial and goblet cell density, snake-like chromatin, HLA-DR-positive and apoptotic cells) and subjectively by the patients. The application of AS eye drops led to a significant improvement in the Schirmer test (p treatment. A significant decrease (p eyes. We found that three-month AS treatment led especially to the improvement of ocular surface dryness and damage of the epithelium. The improvement of dry eye after AS treatment correlated well with the clinical, laboratory and subjective findings. From the patients' subjective point of view, the positive effect of AS decreased with time, but still persisted up to three months after the end of therapy.

    The relationships bewteen blood flow in the cerebrum and the cerebellum was investigated in 21 normal subjects and 21 patients with dementia of the Alzheimer type (DAT). In normal subjects, only asymmetry in the frontal cortical blood flow was significantly correlated with asymmetry in the contralateral cerebellar blood flow. However, a significant correlation between asymmetry in the cerebral cortical blood flow in many areas and the blood flow in the contralateral cerebellum in DAT patients was observed. These results suggest the existence of a functional relationship between the cerebrum and the cerebellum in both normal and DAT groups, mediated by neuronal mechanisms through crossed fiber pathways. However, there are regional differences in the cerebrocerebellar relationship in normal resting and pathological states. (author)

    During the period between 1978 and 1983 a total of 156 patients showing different types of tumours were subjected to high-dosage radiotherapy. The patients were treated repeatedly for primary or recurrent tumours using a radiation dose of >79 Gy. Each of the three largest groups, which were mammary carcinomas (33), cerebral tumours (25) and orohypopharyngeal tumours (22), was analysed individually. In the majority of patients the local effects of this radiotherapy were such that total or at least partial remission of the primary or recurrent tumour appeared most likely. In the groups receiving doses in the lower range the results were just as good as those achieved in subjects exposed to high doses. The survival times determined here for bearers of mammary or cerebral carcinomas were better than the relevant values given in the literature. (orig./MG) [de

    This study explored cross-country differences in the additive effects of socio-economic characteristics, health behaviors and medical comorbidities on subjective health of patients with diabetes. The study analyzed data from the Research on Early Life and Aging Trends and Effects (RELATE). The participants were 9,179 adults with diabetes who were sampled from 15 countries (i.e. China, Costa Rica, Puerto Rico, United States, Mexico, Argentina, Barbados, Brazil, Chile, Cuba, Uruguay, India, Ghana, South Africa, and Russia). We fitted three logistic regressions to each country. Model I only included socio-economic characteristics (i.e. age, gender, education and income). In Model II, we also included health behaviors (i.e. smoking, drinking, and exercise). Model III included medical comorbidities (i.e. hypertension, respiratory disease, heart disease, stroke, and arthritis), in addition to the previous blocks. Our models suggested cross-country differences in the additive effects of socio-economic characteristics, health behaviors and comorbidities on perceived health of patients with diabetes. Comorbid heart disease was the only condition that was consistently associated with poor subjective health regardless of country. Countries show different profiles of social and behavioral determinants of subjective health among patients with diabetes. Our study suggests that universal programs that assume that determinants of well-being are similar across different countries may be over-simplistic. Thus instead of universal programs that use one protocol for health promotion of patients in all countries, locally designed interventions should be implemented in each country.

    A major predicament for Intensive Care Unit (ICU) patients is inconsistent and ineffective communication means. Patients rated most communication sessions as difficult and unsuccessful. This, in turn, can cause distress, unrecognized pain, anxiety, and fear. As such, we designed a portable BCI system for ICU communications (BCI4ICU) optimized to operate effectively in an ICU environment. The system utilizes a wearable EEG cap coupled with an Android app designed on a mobile device that serves as visual stimuli and data processing module. Furthermore, to overcome the challenges that BCI systems face today in real-world scenarios, we propose a novel subject-specific Gaussian Mixture Model- (GMM-) based training and adaptation algorithm. First, we incorporate subject-specific information in the training phase of the SSVEP identification model using GMM-based training and adaptation. We evaluate subject-specific models against other subjects. Subsequently, from the GMM discriminative scores, we generate the transformed vectors, which are passed to our predictive model. Finally, the adapted mixture mean scores of the subject-specific GMMs are utilized to generate the high-dimensional supervectors. Our experimental results demonstrate that the proposed system achieved 98.7% average identification accuracy, which is promising in order to provide effective and consistent communication for patients in the intensive care.

    This aim of this study was to determine the reliability and validity of an established ideomotor apraxia test when applied to a Turkish stroke patient population and to healthy controls. The study group comprised 50 patients with right hemiplegia and 36 with left hemiplegia, who had developed the condition as a result of a cerebrovascular accident, and 33 age-matched healthy subjects. The subjects were evaluated for apraxia using an established ideomotor apraxia test. The cut-off value of the test and the reliability coefficient between observers were determined. Apraxia was found in 54% patients with right hemiplegia (most being severe) and in 25% of left hemiplegic patients (most being mild). The apraxia scores for patients with right hemiplegia were found to be significantly lower than for those with left hemiplegia and for healthy subjects. There was no statistically significant difference between patients with left hemiplegia and healthy subjects. It was shown that the ideomotor apraxia test could distinguish apraxic from non-apraxic subjects. The reliability coefficient among observers in the study was high and a reliability study of the ideomotor apraxia test was therefore performed.

    Full Text Available Abstract: Objective: The aim of this study was to identify symptoms associated with subjective memory complaints among subjects who are currently on sick leave due to symptoms of chronic pain, fatigue, depression, anxiety and insomnia. Methods: This was a cross-sectional study, subjects (n = 167 who were currently on sick leave were asked to complete an extensive survey consisting of the following: items addressing their sociodemographics, one item from the SF-8 health survey measuring pain, Chalder Fatigue Questionnaire, Hospital Anxiety and Depression Scale, Insomnia Severity Index and Everyday Memory Questionnaire – Revised. General linear modeling (GLM was used to analyze variables associated with SMCs. Results: Symptoms of fatigue (p-value <= 0.001 and anxiety (p-value = 0.001 were uniquely and significantly associated with perceived memory failures. The associations with symptoms of pain, depression and insomnia were not statistically significant. Conclusions: Subjective memory complaints should be recognized as part of the complex symptomatology among patients who report multiple symptoms, especially in cases of fatigue and anxiety. Self-report questionnaires measuring perceived memory failures may be a quick and easy way to incorporate and extend this knowledge into clinical practice.

    The Scored Patient-Generated Subjective Global Assessment (PG-SGA) is used internationally as the reference method for proactive risk assessment (screening), assessment, monitoring and triaging for interventions in patients with cancer. This review aims to explain the rationale behind and data supporting the PG-SGA, and to provide an overview of recent developments in the utilization of the PG-SGA and the PG-SGA Short Form. The PG-SGA was designed in the context of a paradigm known as 'anabolic competence'. Uniquely, the PG-SGA evaluates the patient's status as a dynamic rather than static process. The PG-SGA has received new attention, particularly as a screening instrument for nutritional risk or deficit, identifying treatable impediments and guiding patients and professionals in triaging for interdisciplinary interventions. The international use of the PG-SGA indicates a critical need for high-quality and linguistically validated translations of the PG-SGA. As a 4-in-1 instrument, the PG-SGA can streamline clinic work flow and improve the quality of interaction between the clinician and the patient. The availability of multiple high-quality language versions of the PG-SGA enables the inclusion of the PG-SGA in international multicenter studies, facilitating meta-analysis and benchmarking across countries.

    Periodontal diseases, which result from inflammation of tooth supporting tissues, are highly prevalent worldwide. Myeloperoxidase (MPO), from certain white blood cells in saliva, is a biomarker for inflammation. We report our study on the salivary MPO activity and its association with severity of periodontal diseases among Thai patients. Periodontally healthy subjects (n = 11) and gingivitis (n = 32) and periodontitis patients (n = 19) were enrolled. Assessments of clinically periodontal parameters were reported as percentages for gingival bleeding index (GI) and bleeding on probing (BOP), whereas pocket depth (PD) and clinical attachment loss (CAL) were measured in millimeters and then made to index scores. Salivary MPO activity was measured by colorimetry using 3,3'-diaminobenzidine as substrate. The results showed that salivary MPO activity in periodontitis patients was significantly higher than in healthy subjects (p = 0.003) and higher than in gingivitis patients (p = 0.059). No difference was found between gingivitis and healthy groups (p = 0.181). Significant correlations were observed (p < 0.01) between salivary MPO activity and GI (r = 0.632, p < 0.001), BOP (r = 0.599, p < 0.001), PD (r = 0.179, p = 0.164), and CAL (r = 0.357, p = 0.004) index scores. Sensitivity (94.12%), specificity (54.55%), and positive (90.57%) and negative (66.67%) predictive values indicate that salivary MPO activity has potential use as a screening marker for oral health of the Thai community.

    Signs of pharyngeal neurodegeneration have been detected in patients with obstructive sleep apnea (OSA). Along with this neurodegeneration, a decreased pharyngeal sensitivity to mechanical stimulation has been described. The decreased sensitivity may play a role in the pathophysiology of this disease. The aim of the study was to investigate the chemosensitivity of the pharyngeal mucosa in patients with OSA compared with controls. Healthy controls and patients with OSA (age: 30-60 years) were included. Testing of oropharyngeal chemosensitivity was performed with subjective intensity ratings of capsaicin (SIR, visual analogue scale 0-10), air puffs (presented with an olfactometer), and stimulation with CO2 at the posterior pharyngeal wall. A 2-point discrimination test at the soft palate, an intensity rating of capsaicin at the tongue, and a nasal lateralization test were performed. Twenty-six patients with OSA and 18 healthy controls were included. No differences were detected in the SIR of capsaicin at the tongue or in the nasal lateralization test. At the pharynx, a decreased sensitivity to capsaicin (OSA: 6.8 ± 2.3; healthy control: 8.6 ± 1.3), air puffs (OSA: 2.8 ± 1.9; healthy control: 4.2 ± 1.6), and stimulation with CO2 (OSA: 1.5 ± 1.7; healthy control: 2.8 ± 1.8) were demonstrated in patients with OSA (all P < 0.05). Two-point discrimination at the soft palate was reduced with statistical significance in the OSA group (OSA: 11.5 ± 5.4 mm; healthy control: 5.0 ± 2.4 mm). The results suggest reduced pharyngeal chemosensitivity in OSA patients in addition to the reduced mechanical pharyngeal sensitivity shown with 2-point discrimination. This demonstrates peripheral neurodegeneration in the context of this disease.

    Objective: To examine the contributions of subjective cognitive complaints to functional disability in patients with borderline personality disorder (BPD) and their nonaffected relatives. Method: Patients with BPD (n = 26), their first-degree biological relatives (n = 17), and nonpsychiatric control subjects (n = 31) completed a self-report measure of cognitive difficulties and rated the severity of their functional disability on the World Health Organization Disability Assessment Schedule 2.0. Results: After accounting for group differences in age and severity of depressive symptoms, patients and relatives endorsed more inattention and memory problems than control subjects. Whereas probands reported greater disability than relatives and control subjects across all functional domains, relatives described more difficulties than control subjects in managing multiple life activities, including domestic activities and occupational and academic functioning, and participating in society. For both probands and relatives, inattention and memory problems were linked primarily to difficulties with life activities, independent of depression and other comorbid psychiatric disorders. Conclusions: Problems with inattention and forgetfulness may lead to difficulties carrying out activities of daily living and occupational or academic problems in patients with BPD, as well as their nonaffected first-degree relatives.

    To assess the correlations between a patient's subjective perception of metamorphopsia and the clinical measurements of metamorphopsia by M-CHARTS and PreView PHP (PHP). The authors designed a 10-item questionnaire focusing on the symptoms of metamorphopsia and verified its validity with a Rasch analysis. M-CHARTS measured the minimum visual angle of a dotted line needed to detect metamorphopsia, and PHP used the hyperacuity function for detection. Subjects were 39 patients with idiopathic epiretinal membrane (ERM), 22 patients with idiopathic macular hole (M-hole), 19 patients with age-related macular degeneration (AMD), and 51 healthy controls. Rasch analysis suggested the elimination of one question. The nine-item questionnaire score significantly correlated to the M-CHARTS score in ERM (r = 0.59; P = 0.0004) but not in M-hole and to the PHP result in AMD (r = -0.29; P = 0.04) but not in ERM. Eighty percent of ERM patients with greater horizontal M-CHARTS score subjectively perceived horizontal metamorphopsia more often. M-CHARTS showed better sensitivities than PHP in both ERM (89% vs. 42%) and AMD (74% vs. 68%) and better specificity (100% vs. 71%) in healthy controls. Rasch analysis indicated that the present form of the questionnaire is better suited for moderate to severe cases of metamorphopsia than for mild cases. The questionnaire appears to be a valid assessment of patient subjective perception of metamorphopsia and can be used to supplement the clinical measurements of metamorphopsia by M-CHARTS and PHP in patients with macular diseases.

    The aetiology of Oral Lichen Planus (OLP), a chronic inflammatory disease of oral mucosa, is not yet well understood. Since innate immunity may be hypothesized as involved in the susceptibility to OLP, we studied human beta defensin 1 (hBD-1) an antimicrobial peptide constitutively expressed in the saliva, looking at functional genetic variants possibly able to diminish hBD-1 production an consequently conferring major susceptibility to OLP. We analysed three DEFB1 polymorphisms at 5' UTR, -52G>A (rs1799946), -44C>G (rs1800972), -20G>A (rs11362) and two DEFB1 polymorphisms at 3'UTR, c*5G>A (rs1047031), c*87A>G (rs1800971), with the aim of correlating these genetic variants and hBD-1 salivary level in a group of OLP patients and in healthy subjects. We also evaluated hBD-1 salivary concentrations, using ELISA, in OLP and healthy controls. We compared hBD-1 concentrations in OLP and healthy subjects: hBD-1 concentration was significantly higher in OLP patients respect to control. When considering the correlation between DEFB1 polymorphisms genotypes and hBD-1 expression levels, significant results were obtained for SNPs -52G>A (p=0.03 both in OLP patients and healthy individuals) and -44C>G (p=0.02 in OLP patients). hBD-1 production was different between OLP and healthy subjects (not age-matched with OLP). DEFB1 gene polymorphisms, -52G>A and -44C>G, correlated with hBD-1 salivary concentrations. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Candida albicans has a variety of virulence factors, including secreted aspartyl proteases, which are determinant factors in the pathogenesis of this yeast in immunocompromised patients. Proteinase activity was identified in C. albicans strains isolated from the oral cavity of immunocompromised patients with cancer, diabetes and HIV+, with oral candidiasis and in healthy subjects. Two hundred and fifty C. albicans strains were analyzed, distributed in 5 different groups: patients with cancer, diabetes, HIV+, with oral candidiasis and healthy subjects. Proteolytic activity was identified in 46% of the strains from cancer patients, 54% from HIV+ patients, 60% from diabetics, 70% from oral candidiasis patients, and 42% from healthy subjects. Activity was higher in strains from immunocompromised and oral candidiasis patients than in healthy subjects. Differences were observed between the candidiasis-healthy, candidiasis-HIV+, and diabetic-healthy groups. No differences were observed between the oral candidiasis, diabetes and cancer patients, between the diabetes and HIV+ patients, or between the cancer patients, HIV+ patients and healthy subjects. The present results suggest that although secreted aspartyl proteases are important in the pathogenesis of C. albicans, their activity depends on host conditions.

    The central role of the LDL (=low density lipoproteins) receptor in artherosclerosis was first appreciated when it was shown that its absence was responsible for FH (familial hypercholesterolemia). To determine the high affinity cell surface binding activity in circulating human mononuclear cells (MNCs), these cells were incubated with low concentrations (1-50 μg protein/ml) of 123 I-LDL or 111 In-LDL either in the presence or absence of an excess of unlabeled LDL at 4 deg C for 45 minutes. MNCs of healthy subjects and of heterozygous FH-patients were found to possess high affinity LDL receptors immediately after they were isolated from the blood stream. The results indicate that the FH-patients enclosed in this study possess a reduced number of the same high affinity binding sites as healthy subjects confirming the diagnosis of heterozygous FH. In this study 123 I-LDL binding and 111 In-LDL binding to MNCs has been shown to saturable, reversible and displaceable and time-dependent. 123 I-LDL and 111 In-LDL as well can be recommended for the in-vitro determination of LDL-receptor binding activity as both binding processes show approximately the same characteristics.

    The relationship between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) has not yet been fully clarified. The aim of the present study was to analyze DSM-IV OCPD prevalence rates in OCD and panic disorder (PD) patients to test for the specificity of the OCPD-OCD link, and to compare them to OCPD prevalence in a control group of subjects without any psychiatric disorder. A total of 109 patients with a principal diagnosis of DSM-IV (SCID-I) OCD and 82 with PD were interviewed using the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) in order to assess the prevalence of OCPD. All patients with a coexisting axis I diagnosis were excluded from the study to eliminate confounding factors when evaluating the association between prevalence rates of OCPD and anxiety disorder diagnoses. An exclusion criteria was also a Hamilton Depression Rating Scale (HAM-D) score >/=16. A sample of comparison subjects (age 18 to 65 years) without any psychiatric disorder was recruited from people registered with two general practitioners (GPs), whether or not they consulted the doctor, in order to evaluate OCPD prevalence rate in the community. A significant difference was found between the prevalence of OCPD in OCD (22.9%) and in PD (17.1%) on one hand, and that in the comparison sample (3.0%) on the other. No differences were found between the two psychiatric groups, even when splitting the samples according to gender. Our study failed to support the hypothesis of a specific relationship between OCPD and OCD; we confirmed the higher prevalence rate of this personality disorder in OCD subjects with regard to the general population, but we also confirmed the higher rate of OCPD in another anxiety disorder which is phenomenologically well characterized and different from OCD, such as PD.

    To evaluate whether endothelium-dependent (nitric oxide-mediated) dilation of the brachial artery (BA) is impaired in patients being treated for essential hypertension (EH), and whether this abnormality can be detected in normotensive offspring of subjects with EH (familial trait, FT); and to investigate the interrelationship between flow-mediated vasodilation (FMD) and hyperinsulinaemia/insulin resistance. Cross-sectional study. Angiology department at a teaching hospital. The study encompassed 172 subjects, of whom 46 were treated hypertonics aged 40-55 (49) years, and 44 age-matched, normotensive volunteers as controls. We also investigated 41 normotonics with FT aged 20-30 (25) years and 41 age-and sex-matched controls without FT. Using high-resolution ultrasound, BA diameters at rest, during reactive hyperaemia (endothelium-dependent dilation) and after sublingual glyceryl trinitrate (GTN) application (endothelium-independent dilation) were measured. In hypertonics FMD was significantly lower than in controls [2.4 (2.9) vs. 7.4 (2.5)%; P < 0.00005], as was GTN-induced dilation [12.1 (4.3) vs. 16.1 (4.6)%; P=0.0007]. In subjects with FT, FMD was also decreased compared with the control group [5.8 (4.1) vs. 10.0 (3.0)%; P < 0.00005]. The response to GTN was comparable in both groups of young subjects. FMD was negatively related to insulin concentration in all subjects studied (P < 0.00005). In treated patients with EH, flow-mediated dilation of the BA as well as endothelium-independent dilation are decreased. In individuals with FT the endothelial function of the peripheral arteries is also altered in the absence of elevated blood pressure. Endothelial dysfunction is related to hyperinsulinaemia/insulin resistance, which could be one of the pathogenetic determinants of EH and its complications.

    Full Text Available Introduction: Impairment disorders are often found in patients with stroke and impairment of motor and cognitive functions. This is a very serious complication because, by imposing a motor impairment, it aggravates the condition of disability and makes it difficult to conduct physical rehabilitation.The resulting neurological deficits due to stroke determine functional disorders. The possibility of locomotion is usually compromised, therefore the risk of falls increases significantly. The aim of the work is to present Postural Assesment Scale for Strock PASS with the postural stroke assessment scale, the impact of early rehabilitation of patients staying in the neurology ward.Material and methods: Postural examination was carried out among 17 people, of which 8 were women, and 9 were male. The study was divided into two stages. The first stage occurred immediately after the stroke and the second one before the patient was discharged from the ward. Research was carried out at the Biegański Specialist Hospital in Grudziądz in the Department of Neurology and Clinical Neuroimmunology and Impact Department.Conclusions: The results of the postural studies carried out in people with previous stroke subjected to early physiotherapy have a beneficial effect of the conducted therapy. There are positive changes between the first and the final examination of the patients.

    Can vitamin D deficiency be predicted by patient questionnaire? Does it lead to secondary hyperparathyroidism that may cause excessive bone resorption? We studied non-osteoporotic subjects in their fifties, in whom vitamin D levels are often tested. Patients hospitalised for degenerative osteoarthritis or consulting for assessment of menopause, without renal failure and not treated with vitamin D, completed a questionnaire on sun exposure and underwent measurement of serum calcium, creatinine, 25OH vitamin D, PTH and CTX. Five hundred and twenty-six subjects, mean age 54.6 years (71% women), were investigated throughout the year. 25OH vitamin D levels were correlated with sun exposure and varied according to the month of the year, unlike PTH and CTX levels. From November to May, over 90% of subjects had 25OH vitamin D levelssecondary hyperparathyroidism, characterised by serum calcium65pg/mL, associated with increased CTX levels. Vitamin D deficiency can be predicted by patient questionnaire. It very rarely leads to secondary hyperparathyroidism. Copyright © 2015. Published by Elsevier Masson SAS.

    The gut microbiota is a reservoir of opportunistic pathogens that can cause life-threatening infections in critically ill patients during their stay in an intensive care unit (ICU). To suppress gut colonization with opportunistic pathogens, a prophylactic antibiotic regimen, termed "selective decontamination of the digestive tract" (SDD), is used in some countries where it improves clinical outcome in ICU patients. Yet, the impact of ICU hospitalization and SDD on the gut microbiota remains largely unknown. Here, we characterize the composition of the gut microbiota and its antimicrobial resistance genes ("the resistome") of ICU patients during SDD and of healthy subjects. From ten patients that were acutely admitted to the ICU, 30 fecal samples were collected during ICU stay. Additionally, feces were collected from five of these patients after transfer to a medium-care ward and cessation of SDD. Feces from ten healthy subjects were collected twice, with a 1-year interval. Gut microbiota and resistome composition were determined using 16S rRNA gene phylogenetic profiling and nanolitre-scale quantitative PCRs. The microbiota of the ICU patients differed from the microbiota of healthy subjects and was characterized by lower microbial diversity, decreased levels of Escherichia coli and of anaerobic Gram-positive, butyrate-producing bacteria of the Clostridium clusters IV and XIVa, and an increased abundance of Bacteroidetes and enterococci. Four resistance genes (aac(6')-Ii, ermC, qacA, tetQ), providing resistance to aminoglycosides, macrolides, disinfectants, and tetracyclines, respectively, were significantly more abundant among ICU patients than in healthy subjects, while a chloramphenicol resistance gene (catA) and a tetracycline resistance gene (tetW) were more abundant in healthy subjects. The gut microbiota of SDD-treated ICU patients deviated strongly from the gut microbiota of healthy subjects. The negative effects on the resistome were limited to selection

    In spondylolisthesis, it is believed that as L5 slips on S1, the pedicle may become elongated in response to the instability in an attempt to bridge the defect. Whether patients with spondylolysis, which is largely developmental, also develop elongation of the pedicles is unknown. The purpose of this study is to evaluate and quantify the increase in L5 pedicle length in subjects with spondylolysis as compared with normal healthy subjects. Nine hundred fifty-two human cadaveric specimens without spondylolysis and 120 specimens with spondylolysis from the Hamann-Todd Osteological Collection were examined by a single examiner. Baseline data, including age, sex, and race of specimens, were collected. Digital calipers were used to measure the pedicle lengths at the L5 level. Linear regression analysis was performed to compare the L5 pedicle lengths in healthy patients and patients with spondylolysis. Linear regression showed a significant association of increased L5 pedicle length in subjects with spondylolysis. The average L5 pedicle length in subjects with spondylolysis was greater compared with subjects without spondylolysis. In spondylolytic specimens, pedicles start to elongate after the age of 40 years. The pedicle lengths increase progressively from 5.6 mm at 40 years to 6.7 mm at 80 years with a 1% to 3% increment every decade. The pedicle lengths showed little variation in specimens from healthy subjects. In spondylolytic specimens, there is progressive elongation of L5 pedicle length after the third decade. An increase in L5 pedicle length in all age groups compared with the specimens from healthy subjects suggests that pathologic changes occur in bony anatomy of L5 vertebrae as early as adolescence when the condition develops.

    BACKGROUND AND PURPOSE: Previous volumetric magnetic resonance imaging (MRI) studies of Parkinson's disease (PD) utilized primarily voxel-based morphometry (VBM), and investigated mostly patients with moderate- to late-stage disease. We now use deformation-based morphometry (DBM), a method...... purported to be more sensitive than VBM, to test for atrophy in patients with early-stage PD. METHODS: T1-weighted MRI images from 24 early-stage PD patients and 26 age-matched normal control subjects were compared using DBM. Two separate studies were conducted, where two minimally-biased nonlinear...... intensity-average were created; one for all subjects and another for just the PD patients. The DBM technique creates an average population-based MRI-average in an iterative hierarchical fashion. The nonlinear transformations estimated to match each subject to the MRI-average were then analysed. RESULTS...

    The major goal of evoked related potential studies arise in source localization techniques to identify the loci of neural activity that give rise to a particular voltage distribution measured on the surface of the scalp. In this paper we evaluate the effect of the head model adopted in order to estimate the N170 component source in attention deficit hyperactivity disorder (ADHD) patients and control subjects, considering faces and words stimuli. The standardized low resolution brain electromagnetic tomography algorithm (sLORETA) is used to compare between the three shell spherical head model and a fully realistic model based on the ICBM-152 atlas. We compare their variance on source estimation and analyze the impact on the N170 source localization. Results show that the often used three shell spherical model may lead to erroneous solutions, specially on ADHD patients, so its use is not recommended. Our results also suggest that N170 sources are mainly located in the right occipital fusiform gyrus for faces stimuli and in the left occipital fusiform gyrus for words stimuli, for both control subjects and ADHD patients. We also found a notable decrease on the N170 estimated source amplitude on ADHD patients, resulting in a plausible marker of the disease.

    Full Text Available Oral doxepin rinse has been reported to provide pain relief in patients with oral mucosal lesions due to cancer or cancer therapy. The purpose of this study was to assess the anesthetic effect of doxepin oral rinse in normal subjects to identify the duration of effect and to contrast the anesthetic effect with reported pain relief in patients with oral mucosal lesions. Normal volunteers were provided a solution of doxepin (5 mg/mL for oral rinsing. Oral numbness and adverse effects were recorded for a period of 4 h after rinsing. Doxepin rinse resulted in mucosal anesthesia in all subjects. Sedation/fatigue was reported in four of seven subjects. There were no taste complaints and no nausea reported. The limited duration of numbness/anesthesia in normal subjects compared with prior studies showing pain relief for more than 3 h in patients with mucosal lesions, suggests that the extended duration of pain relief in patients was due to analgesic effects rather than anesthetic effects. The majority of normal subjects reported sedation after use, but this was less common in patients with mucosal lesions.

    Fibromyalgia is a chronic pain syndrome associated with numerous somatic symptoms including gastrointestinal manifestations of nonspecific nature. Celiac disease and nongluten sensitivity frequently evolve in adults with gastrointestinal and extraintestinal symptoms similar to those found among patients with fibromyalgia. The objective of the present study was to evaluate the presence of celiac-type symptoms among patients with fibromyalgia in comparison with healthy subjects and with those experienced by adult celiac patients and subjects with gluten sensitivity. A list of typical celiac-type symptoms was developed, comparing the frequency of presentation of these symptoms between patients with fibromyalgia (N = 178) and healthy subjects (N = 131), in addition to those of celiac patients and gluten-sensitive patients reported in the literature. The frequency of presentation of every celiac-type symptom, excepting anemia, was significantly higher among patients with fibromyalgia compared to controls (p symptoms and cutaneous lesions predominated among patients with fibromyalgia, whereas the prevalence of gastrointestinal symptoms was higher among patients with fibromyalgia compared to gluten-sensitive patients and was similar among patients with fibromyalgia and celiac disease patient. The symptomatological similarity of both pathologies, especially gastrointestinal symptoms, suggests that at least a subgroup of patients with fibromyalgia could experience subclinical celiac disease or nonceliac gluten intolerance.

    Cine MR imaging was performed on 15 normal subjects and 27 patients with cardiac disease. In normal subjects, high signal intensity of flowing blood contrasted with that of the myocardium. In 16 patients with valvular regurgitation, signal void jet due to turbulence was visualized across the diseased valves. In three IHSS patients, thickened LV myocardium, mitral regurgitant jets, and systolic LV outflow jets were noted. Five patients with myocardial infarction (MI) showed thinning and/or hypokinesis of MI regions. In three patients with Marfan syndrome, aortic dilatation, insufficiency, and flap (one pt) were identified. Cine MR imaging is potentially useful for evaluation of a variety of cardiac diseases

    This explorative survey investigated clients’ evaluation of therapy elements and other supportive factors within a randomized controlled trial. The treatment of patients with alcohol dependence consisted of pharmacotherapy (acamprosate/naltrexone/placebo) and biweekly medical management (MM). Forty-nine study participants were surveyed with a questionnaire to measure both the patients’ satisfaction with the therapy and the subjective assessment of treatment elements and supportive factors. Study participants were highly satisfied with the treatment. The supportive factors previously identified by Orford et al1 were confirmed. ‘Pharmacotherapy’ was rated significantly less effective than ‘MM’ and ‘global study attendance’ (P < 0.001). The significant differences in the evaluation of treatment elements point to a preference for regular low-key contacts rather than for medication. Such contacts based on MM could be a useful intervention in clinical care, and its effectivity should be examined more closely in further research. PMID:22879748

    The aim of the study was to identify the anatomical bases involved in the subjective experience of time, by means of a voxel based symptom-lesion mapping (VLSM) study on patients with focal brain damage. Thirty-three patients (nineteen with right-hemisphere lesions -RBD, and fourteen with left lesion- LBD) and twenty-eight non-neurological controls (NNC) underwent the semi-structured QUEstionnaire for the Subjective experience of Time (QUEST) requiring retrospective and prospective judgements on self-relevant time intervals. All participants also completed tests to assess general cognitive functioning and two questionnaires to evaluate their emotional state. Both groups of brain-damaged patients achieved significantly different scores from NNC on the time performance, without differences between RBD and LBD. VLSM showed a cluster of voxels located in the right inferior parietal lobule significantly related to errors in the prospective items. The lesion subtraction analysis revealed two different patterns possibly associated with errors in the prospective items (the right inferior parietal cortex, rolandic operculum and posterior middle temporal gyrus) and in the retrospective items (superior middle temporal gyrus, white matter posterior to the insula).

The long-term results are compared to the 6-week follow-up outcomes.Patients and methods: Two hundred and seventeen surgery patients were surveyed at 6 weeks, and 206 patients at 12 months after discharge from the trauma surgical general ward. The subjective evaluation of medical treatment outcome was measured 6 weeks and 12 months after discharge with the respective scale from the Cologne Patient Questionnaire. Physician Empathy was assessed with the Consultation and Relational Empathy Measure. The correlation between physician empathy and control variables with the subjective evaluation of medical treatment outcome 12 months after discharge was identified by means of logistic regression analysis under control of sociodemographic and injury-related factors.Results: One hundred and thirty-six patients were included within the logistic regression analysis at the 12-month follow-up. Compared to the 6-week follow-up, the level of subjective evaluation of medical treatment outcome was slightly lower and the association with physician empathy was weaker. Compared to patients who rated the empathy of their surgeon lower than 31 points, patients

    Full Text Available Context A review of the literature of recent decades has shown that few studies have been conducted on the effects of various types of complementary medicine on patients with leukemia. Therefore, the present study aimed to find research gaps in the use of different types of complementary medicine in patients with leukemia to be applied in future studies. Evidence Acquisition The present study was a review-type design based on a review of the literature on different types of complementary medicine in patients with leukemia, up to 2015. The search was conducted through electronic databases and search engines. According to the inclusion and exclusion criteria, 8 studies which had been conducted on the use of complementary medicine in patients with leukemia were selected for the identification of gaps. Results The overall results showed that few studies have been conducted on the use of exercise, massage therapy, music therapy, acupressure, and healing touch in patients with leukemia, and these subjects are potential research areas for many different studies. However, no studies have been carried out on the effects of acupuncture, relaxation, and yoga on these patients. Conclusions The results of this review showed that the number of studies on the use of complementary medicine in leukemia patients is very limited (especially in Iran, and it can be the subject of numerous studies in the future.

    Cognitive and behavioral impairments are common in patients with abnormal thyroid function; these impairments cause a reduction in their quality of life. The current study investigates the decision making performance in patients with hyperthyroidism to explore the possible mechanism of their cognitive and behavioral impairments. Thirty-eight patients with hyperthyroidism and forty healthy control subjects were recruited to perform the Iowa Gambling Task (IGT), which assessed decision making under ambiguous conditions. Patients with hyperthyroidism had a higher score on the Zung Self-Rating Anxiety Scale (Z-SAS), and exhibited poorer executive function and IGT performance than did healthy control subjects. The patients preferred to choose decks with a high immediate reward, despite a higher future punishment, and were not capable of effectively using feedback information from previous choices. No clinical characteristics were associated with the total net score of the IGT in the current study. Patients with hyperthyroidism had decision-making impairment under ambiguous conditions. The deficits may result from frontal cortex and limbic system metabolic disorders and dopamine dysfunction.

    Full Text Available The purpose of this study was to quantify the metabolic equivalents (METs of resistance exercise in obese patients with type 2 diabetes (T2DM and healthy young subjects and to evaluate whether there were differences between sessions executed at low- versus high-intensity resistance exercise. Twenty obese patients with T2DM (62.9±6.1 years and 22 young subjects (22.6±1.9 years performed two training sessions: one at vigorous intensity (80% of 1-repetition maximum (1RM and one at moderate intensity (60% of 1RM. Both groups carried out three strength exercises with a 2-day recovery between sessions. Oxygen consumption was continuously measured 15 min before, during and after each training session. Obese T2DM patients showed lower METs values compared with young healthy participants at the baseline phase (F= 2043.86; P<0.01, during training (F=1140.59; P<0.01 and in the post-exercise phase (F=1012.71; P<0.01. No effects were detected in the group x intensity analysis of covariance. In this study, at both light-moderate and vigorous resistance exercise intensities, the METs value that best represented both sessions was 3 METs for the obese elderly T2DM patients and 5 METs for young subjects.

    The present study examines the most common home remedies in the Piedmont region of northwest Italy currently used in the treatment of pediatric enterobiasis, commonly known as pinworm infection. The remedies in question, typically based on popular beliefs and as such are nearly useless, were noted through interviews with subjects who had come to the local Hygiene and Public Health Services offices for information about pinworm prevention and treatment. Analysis of replies by the subjects clearly indicates that local families are ill-prepared to recognize the symptoms this parasitic infection; often it is confused with pediatric ketosis, therefore leading to inappropriate treatment which at times may be potentially harmful to the patient.

    The Night Eating Syndrome (NES) is a disorder characterized by the clinical features of morning anorexia, evening hyperphagia, and insomnia with awakenings followed by nocturnal food ingestion. The core clinical feature appears to be a delay in the circadian timing of food intake. The diagnosis and early treatment of NES may represent an important means of prevention for obesity. Aims. The aim of the present study was to determine the vulnerability to develop NES between a clinical sample of patients with psychiatric disorders and a non clinical sample. We investigated a possible relation between stress and a dysfunctional eating behaviors as NES. Methods. The Night Eating Questionnaire (NEQ) has been administered to 147 psychiatric outpatients and to 531 subjects attending the University of L'Aquila. The NEQ is a questionnaire used to evaluate the prevalence of NES. The sample has been also evaluated through the Stress-related Vulnerability Scale (SVS) to measure both perceived stress and social support. Results. The 8.2% of patients scored above the diagnostic cut-off of the NEQ, compared to the 2.1% in the sample of healthy subjects. The majority of patients who had shown NEQ>25 had a diagnosis of major depressive disorder (MDD). The total scores on the NEQ were strongly associated with the SVS total score and especially with the "lack of social support" subscale. Conclusions. This study shows the increased vulnerability of NES in the sample of psychiatric patients compared to the sample of healthy subjects. The study further confirms the strong association between perceived stress, social support, altered eating behaviors and obesity.

    This study was a cephalometric evaluation of the growth changes in untreated subjects with minimal overbite at 4 time points during 4 developmental stages from the early mixed dentition to the permanent dentition, as well as from the prepubertal phase to young adulthood. A sample of 24 untreated subjects with minimal overbite (<1.5 mm) was selected retrospectively from the University of Michigan Growth Study and the Denver Child Growth Study. The sample was followed longitudinally from about 9 years of age through 17 years of age. Dentofacial changes at the 4 times (T1-T4), defined by the cervical vertebral maturation method, were analyzed on lateral cephalograms. Nonparametric statistical analysis was used for comparisons. Overbite on average increased by 2.3 mm during the overall observation period. Improvement occurred during the prepubertal interval (T1-T2; 2.4 mm), whereas no significant changes occurred in the pubertal and postpubertal stages. From prepubertal ages to young adulthood, the open-bite tendency improved in 91% of the subjects, with self-correction in 75%. Logistic regression analysis on the cephalometric variables at T1 with the value of overbite at T4 did not show a statistically significant correlation. Subjects with an open-bite tendency show improvement of their occlusal condition during the prepubertal stage, but there is no significant improvement after this. These results provide useful indications for appropriate orthodontic treatment timing for patients with an open-bite tendency. Copyright © 2014 American Association of Orthodontists.

    Full Text Available The mechanism of the neuromuscular system’s disorders in Adolescent Idiopathic Scoliosis (AIS are not well known. The objectives of this study were to assess the dynamic balance of the AIS patients and the influence of exercise therapy on patients' dynamic balance. Eleven teenager scoliotic subjects after three months exercise therapy, nine similar patients without therapy and 13 healthy age matched subjects as control group were studied. Using dynamic stability platform, the deviation of COG of subjects in different positions, including up right standing, standing with head flexion and standing with head hyper extension were measured. The tests were repeated in both lose and stable condition of the foot platform. Results showed that the stability of the foot platform resulted in COG's deviation by 1.13 0.08 in all subjects. Dynamic balance of scoliotic patients without treatment was similar to that of the normal subjects. While, exercised patients had less COG deviation than the other groups. The change in head position increased the COG deviation by 2.5 times in control and non-exercised patients and 1.5 times in exercised patients. The dynamic balance in scoliosis was not affected. Exercise improved the dynamic balance in scoliotic subjects. Exercise therapy is recommended to improve the proprioceptives function.

    1 The effects of single doses (25 g and 50 g) oral ethanol on the disposition of acetanilide (50 mg/kg metabolic active mass) has been studied in normal subjects, and in patients with chronic non-alcoholic liver disease. 2 In normal subjects, ethanol produced a dose-dependent increase in acetanilide half-life, and a decrease in acetenilide clearance. There was a significant correlation (rs = 0.71, P less than 0.01) between the 90 min blood ethanol concentration and the reduction in acetanilide clearance. 3 In patients with liver disease, ethanol produced a similar proportional change in acetanilide half-life and clearance, but these were less consistent. Moreover, liver disease itself was associated with an increase in acetenilide half-life, and a reduction in clearance. 4 It is concluded that single oral doses of ethanol, comparable to those consumed during social drinking, may inhibit some forms of microsomal oxidation and thus have important clinical implications.

    Public awareness for dementia is rising and patients with concerns about forgetfulness are not uncommon in general practice. For the general practitioner (GP) subjectively perceived memory impairment (SMI) also offers a chance to broach the issue of cognitive function with the patient. This may support GPs' patient-centered care in terms of a broader frailty concept. What is SMI (definition, operationalization, prevalence and burden)? Which conceptions and approaches do GPs have regarding SMI? Narrative overview of recent SMI criteria and results, selective utilization of results from a systematic literature search on GP dementia care, non-systematic search regarding SMI in general practice, deduction of a study design from the overview and development according to international standards. Studies revealed that approximately 60% of GP patients aged >74 reported a declining memory, every sixth person had concerns about this aspect and only relatively few seek medical advice. Concerns about SMI are considered a risk factor for future dementia. Specific general practice conceptions about SMI could not be identified in the literature. Using guidelines for mixed methods research, the design of an exploratory sequential mixed methods study is presented, which should reveal different attitudes of GPs towards SMI. Subjective memory impairment (SMI) is a common feature and troubles a considerable proportion of patients. Neuropsychiatric research is progressing, but for the transfer of the SMI concept into routine practice, involvement of GP research is necessary. A new study aims to make a contribution to this.

    Periodontal diseases, which result from inflammation of tooth supporting tissues, are highly prevalent worldwide. Myeloperoxidase (MPO), from certain white blood cells in saliva, is a biomarker for inflammation. We report our study on the salivary MPO activity and its association with severity of periodontal diseases among Thai patients. Periodontally healthy subjects (n = 11) and gingivitis (n = 32) and periodontitis patients (n = 19) were enrolled. Assessments of clinically periodontal parameters were reported as percentages for gingival bleeding index (GI) and bleeding on probing (BOP), whereas pocket depth (PD) and clinical attachment loss (CAL) were measured in millimeters and then made to index scores. Salivary MPO activity was measured by colorimetry using 3,3′-diaminobenzidine as substrate. The results showed that salivary MPO activity in periodontitis patients was significantly higher than in healthy subjects (p = 0.003) and higher than in gingivitis patients (p = 0.059). No difference was found between gingivitis and healthy groups (p = 0.181). Significant correlations were observed (p < 0.01) between salivary MPO activity and GI (r = 0.632, p < 0.001), BOP (r = 0.599, p < 0.001), PD (r = 0.179, p = 0.164), and CAL (r = 0.357, p = 0.004) index scores. Sensitivity (94.12%), specificity (54.55%), and positive (90.57%) and negative (66.67%) predictive values indicate that salivary MPO activity has potential use as a screening marker for oral health of the Thai community.

    A new double isotopic method was used to measure the gastrointestinal progression of a meal in nine healthy subjects and seven patients with functional diarrhoea. 51 Chromium chloride (colonic marker) was ingested eight hours before the beginning of the scintigraphic study so that it was by then located in the colon at that time. A second marker, 99m Technetium sulphur colloid labelled the meal. Scintigraphic images were taken before and after the meal for two hours, detecting simultaneously the two isotopes. In the 51Cr window right colon was localised and intracolonic propulsion was studied; and in the 99m Tc window gastric emptying and colon filling of the meal marker was quantified. A propulsive gastrocolic reflex was evidenced in five of the seven patients with functional diarrhoea but in none of the normal subjects. Unabsorbed residues of the meal are propelled rapidly in the ileocaecal region. Small intestinal transit of the meal marker was twice as rapid in patients with functional diarrhoea as in normal subjects.

    Different studies considered the mechanisms involved in the maintenance of binge eating in bulimia nervosa (BN) and binge eating disorder (BED), suggesting different pathways. The present 3-year follow-up study evaluated the relationships between psychopathological variables, and objective and subjective binge eating episodes in the two syndromes. 85 BN and 133 BED patients were studied. Objective and subjective binge eating, and psychopathological data were collected in a face-to-face interview, and by means of different self-reported questionnaires. The same assessment was repeated at baseline (T0), at the end of an individual cognitive-behavioral treatment (T1), and 3 years after the end of treatment (T2). At baseline, BN and BED patients showed different emotions associated with binge eating: anger/frustration for BN and depression for BED patients. Objective binge eating frequency reduction across time was associated with lower impulsivity and shape concern in BN patients, and with lower emotional eating and depressive symptoms in BED patients. Lower subjective binge eating frequency at baseline predicted recovery, in both BN and BED patients. Recovery was associated with lower impulsivity and body shape concern at baseline for BN patients, and lower depression and emotional eating for BED patients. Eating psychopathology, psychiatric comorbidity, impulsivity and emotional eating have a different pattern of association with objective and subjective binge eating in BN and BED patients, and they act as different moderators of treatment. A different target of intervention for these two syndromes might be taken into account, and subjective binge eating deserves an accurate assessment. Copyright © 2011 S. Karger AG, Basel.

    Full Text Available Objectives: The aim of the present study was to use a voxel-based MRI method to investigate the neuroanatomical characteristics in subjects at high risk of developing psychosis compared with those of healthy controls and first-episode schizophrenia patients. Methods: This study included 14 subjects with at-risk mental state (ARMS, 34 patients with first-episode schizophrenia, and 51 healthy controls. We used voxel-based morphometry (VBM with the Diffeomorphic Anatomical Registration Through Exponentiated Lie Algebra (DARTEL tools to investigate the whole-brain difference in gray matter volume among the three groups. Results: Compared with the healthy controls, the schizophrenia patients showed significant gray matter reduction in the left anterior cingulate gyrus. There was no significant difference in the gray matter volume between the ARMS and other groups. Conclusion: The present study suggests that alteration of the anterior cingulate gyrus may be associated with development of frank psychosis. Further studies with a larger ARMS subjects would be required to examine the potential role of neuroimaging methods in the prediction of future transition into psychosis.

    The aim of this survey is to present an overview of research into psychopharmacology as regards the effects of different psychoactive drugs and neuroleptics (NL) on language in normal subjects and schizophrenic patients. Eighteen studies that have investigated the effects of different drugs (alcohol, amphetamines, secobarbital, L-dopa, psilocybin, ketamine, fenfluramine) and neuroleptics (conventional and atypical) on language are reviewed. There are no studies concerning the effects of neuroleptics on language in healthy subjects. The results of the effects of other molecules indicate that language production can be increased (alcohol, amphetamine, secobarbital), rendered more complex (d-amphetamine), more focused (L-dopa) or more unfocused (psilocybin) and clearly impaired (ketamine). For schizophrenic patients, most studies show that conventional neuroleptic treatments, at a therapeutic dosage and in acute or chronic mode, reduce language disorders at all levels (clinic, linguistic, psycholinguistic). In conjunction with other molecules, the classical NL, when administered at a moderate dosage and in chronic mode, modify language in schizophrenia, either by improving the verbal flow and reducing pauses and positive thought disorder (NL + amphetamine) or by inducing an impairment in the language measurements (NL + fenfluramine). Clinical, methodological and theoretical considerations of results are debated in the framework of schizophrenic language disorders.

    Subjective cognitive impairment can be a significant and prevalent problem for gynaecological cancer survivors. The aims of this study were to assess subjective cognitive functioning in gynaecological cancer survivors after primary cancer treatment, and to investigate the impact of cancer treatment on brain structural networks and its association with subjective cognitive impairment. This was a cross-sectional survey using a self-reported questionnaire by the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) to assess subjective cognitive functioning, and applying DTI (diffusion tensor imaging) and graph theoretical analyses to investigate brain structural networks after primary cancer treatment. A total of 158 patients with gynaecological cancer (mean age, 45.86 years) and 130 age-matched non-cancer controls (mean age, 44.55 years) were assessed. Patients reported significantly greater subjective cognitive functioning on the FACT-Cog total score and two subscales of perceived cognitive impairment and perceived cognitive ability (all p values impairment (r = -0.388, p = 0.034). When compared with non-cancer controls, a considerable proportion of gynaecological cancer survivors may exhibit subjective cognitive impairment. This study provides the first evidence of brain structural network alteration in gynaecological cancer patients at post-treatment, and offers novel insights regarding the possible neurobiological mechanism of cancer-related cognitive impairment (CRCI) in gynaecological cancer patients. As primary cancer treatment can result in a more random organisation of structural brain networks, this may reduce brain functional specificity and segregation, and have implications for cognitive impairment. Future prospective and longitudinal studies are needed to build upon the study findings in order to assess potentially relevant clinical and psychosocial variables and brain network measures, so as to more accurately understand the

    During a 5-year period, 81 patients ages 20 to 60 years old had implantation of a permanent cardiac pacemaker at the University Hospital, Odense. At follow-up, during 1985, the 73 survivors received a semi-structured questionnaire regarding subjective consequences of pacemaker therapy, and 72...... people (98.6%) agreed to participate. The mean pacing period (range) was 33.8 (11-72) months. Surgical intervention was required in 14 patients (19.4%) during follow-up. Regarding all symptoms 67 patients (93.1%) perceived benefit from the pacemaker. The effectiveness of cardiac pacing was most...... or a sensation of "impulses"/palpitations.

    Personality theory and research typically focus on chronological age as a key indicator of personality development. This study examines whether the subjective experience of age is an alternative marker of the biomedical and psychosocial factors that contribute to individual differences in personality development. The present study uses data from the Midlife in the United States longitudinal survey (N = 3,617) to examine how subjective age is associated with stability and change in personality and the dynamic associations between subjective age and personality traits over a 10-year period. Regression analyses indicated that a younger subjective age at baseline was associated with increases in Openness, Conscientiousness, and Agreeableness; correlated changes were also found. The rank-order stability of Extraversion and Openness and overall profile consistency were higher among those with a younger subjective age at baseline and were also associated with the rate of subjective aging over time. The present study reveals that beyond chronological age, the age an individual feels is related to changes in characteristic ways of thinking, feeling, and behaving over time. © 2014 Wiley Periodicals, Inc.

    Full Text Available Prior studies suggested that glaucoma patients suffer worse dry eye and mood and sleep disorders than non-glaucoma subjects. Prostaglandin analogues are first-line therapy for glaucoma, inducing few instillation problems and sufficient pressure-reduction effects. This study compared dry eye, sleep quality, and mood status between glaucoma patients receiving prostaglandin monotherapy and non-glaucoma subjects.This cross-sectional study evaluated 1520 patients (579 males and 941 females for glaucoma status and dry eye-related symptoms (dryness, eye fatigue, photophobia, pain, blurring and signs (Schirmer test, tear break-up time, corneal staining scores. Of the total cohort, 93 patients were also evaluated by Pittsburgh sleep quality index (PSQI and hospital anxiety and depression score (HADS. Inclusion criteria were consecutive patients ≥ 51 years of age and best-corrected visual acuity ≥ 20/25. Glaucoma patients included those treated with prostaglandin or a fixed combination including prostaglandin. Exclusion criteria were history of ocular surgery within one month. Data were analyzed using the chi-square or Mann-Whitney U tests, at 5% significance.There were no significant differences in dry eye-related signs and symptoms between the control (n = 1431, mean age of 66.9 years and glaucoma groups (n = 89, 67.9 years. The psychiatric sub-analysis of the control (n = 61, 66.2 years and glaucoma groups (n = 32, 67.3 years revealed mean scores of 5.02 ± 3.10 and 5.16 ± 3.46 for PSQI (normal range ≤ 5, 9.47 ± 5.61 and 9.42 ± 7.36 for HADS (normal range ≤ 10, 4.84 ± 3.22 and 4.71 ± 3.45 for anxiety (normal range ≤ 5, and 4.63 ± 3.05 and 4.71 ± 4.40 for depression (normal range ≤ 5, respectively, without statistical significance.Our results were comparable between glaucoma patients on prostaglandin monotherapy and non-glaucoma subjects for dry eye-related clinical manifestations, sleep quality, and mood status.

    Full Text Available Abstract Background Cold sensitivity is a common and disabling complaint following hand injuries. The main purpose of this study was to describe self-reported consequences of cold sensitivity and the association with disability and health-related quality of life in patients with hand injuries or hand-arm vibration syndrome (HAVS and in normal subjects. Methods Responses to the Cold Intolerance Symptom Severity (CISS questionnaire, Potential Work Exposure Scale (PWES, Disability of the Arm, Shoulder and Hand (DASH and Short-Form 36 questionnaire (SF-36 were investigated in normal subjects (n = 94, hand injured patients (amputation and nerve injuries, n = 88 and patients with HAVS (n = 30. The results are presented as median (range, percent and mean deviation from norms. The Kruskal Wallis Test or Mann-Whitney U-Test were used to identify significant differences between multiple groups or subgroups. The Spearman rank correlation was used to study the relationship between cold sensitivity and disability. Results Abnormal cold sensitivity (CISS score > 50 was seen in 75% and 45% of patients with HAVS and a traumatic hand injury, respectively. Patients were significantly more exposed to cold in their work environment than the normal population, with a consequently negative effect on work ability due to cold sensitivity. Patients with abnormal cold sensitivity were more seriously disabled and had a poorer health-related quality of life than patients with normal cold sensitivity [higher DASH scores and e.g. significantly larger mean deviation from norms in the subscales Role Physical and Bodily Pain (SF-36]. Conclusion Severe and abnormal cold sensitivity may have a profound impact on work capacity, leisure, disability and health-related quality of life. It is frequently seen in patients with traumatic hand injuries and particularly apparent in patients with HAVS.

    The aim of this study was to determine the changes of short chain fatty acids (SCFAs) in faeces of inflammatory bowel disease (IBD) patients compared to healthy subjects. SCFAs such as pyruvic, lactic, formic, acetic, propionic, isobutyric and butyric acids were analyzed by using high performance liquid chromatography (HPLC). This study showed that the level of acetic, 162.0 µmol/g wet faeces, butyric, 86.9 µmol/g wet faeces, and propionic acids, 65.6 µmol/g wet faeces, decreased remarkably in IBD faecal samples when compared with that of healthy individuals, 209.7, 176.0, and 93.3 µmol/g wet faeces respectively. On the contrary, lactic and pyruvic acids showed higher levels in faecal samples of IBD than in healthy subjects. In the context of butyric acid level, this study also found that the molar ratio of butyric acid was higher than propionic acid in both faecal samples. This might be due to the high intake of starch from rice among Malaysian population. It was concluded that the level of SCFAs differ remarkably between faecal samples in healthy subjects and that in IBD patients providing evidence that SCFAs more likely play an important role in the pathogenesis of IBD.

    Full Text Available Narcolepsy type I is characterized by excessive daytime sleepiness (EDS, cataplexy, sleep paralysis, hypnagogic hallucination, and fragmented night-time sleep. Although diagnosis is based on clinical history, it needs to be confirmed by nocturnal polysomnography, followed by a daytime multiple sleep latency test (MSLT. However, EDS, which is the central symptom of the narcolepsy, is unspecific and there could be a disparity between subjective daytime sleepiness and objective daytime sleepiness measured by MSLT. Also, cataplexy, which is the exclusive symptom of narcolepsy, has a wide phenotypical variability and is triggered by a range of stimuli, even without definite identifiable emotional trigger. We report an unusual narcolepsy patient with spontaneous cataplexy, without an identifiable trigger and subjective daytime sleepiness.

    Aim: Analysis of the application of radioactive substances in research in the field of nuclear medicine in human beings and of the resulting radiation exposure to study subjects. Methods: Assessment of applications for approval submitted in accordance with Paragraph 41 of the Radiation Protection Ordinance, evaluated by the Federal office for Radiation Protection together with the Federal Institute for Pharmaceuticals and Medical Products, within the period from 1997 to 1999. Results: The focus of the studies on the diagnostic application of radioactive substances in medicine evaluated has, since 1998, shifted from oncological to neurological and psychological aspects, while, at the same time, the number of PET studies increased constantly The proportion of healthy study subjects included in the diagnostic studies increased from 7 to 22%. The number of therapeutic applications of radioactive substances has, since 1997, undergone a three-fold increase, and in the process of this, the focus of attention lay within the area of radioimmuno-therapy and endovascular brachytherapy. The effective dose was, among up to 49% of the investigated healthy study subjects higher than 5 mSv, and among up to 6% of these subjects was at levels of over 20 mSv. Up to 22% of the patients received, within the scope of diagnostic studies, an effective dose of between 20 and 50 mSv. An exceeding of the 50 mSv limit occurred among up to 3% of the patients. Conclusions: In spite of the increasing numbers of PET applications, conventional nuclear medicine has maintained its importance in the field of medical research. Further developments in the areas of radiochemistry and molecular biology led to an increase in the importance of radio-immuno therapy. The evaluation of new radiopharmaceuticals and the extension of basic biomedical research, resulted in an increase in the proportion of healthy study subjects included in the studies.

    Patients with rotator cuff tear and degenerative shoulder joint disease commonly experience severe pain and reduced performance during activities of daily living. A popular way to treat these patients is by means of reverse anatomy shoulder prosthesis. Studying the kinematics of subjects with reverse anatomy implant would be useful in order to gain knowledge about functionality of different designs. It is hypothesized that the kinematics of these subjects, in the absence of rotator cuff muscles, differs from that of normal subjects. In this study the upper limb kinematics of 12 subjects with a Bayley-Walker reverse anatomy shoulder prosthesis while performing tasks common in everyday activities and those that represent the range of motion was analyzed and compared to that of 12 normal subjects. Each patient also completed an Oxford Shoulder Score. Substantial reduction in the Bayley-Walker subjects' ranges of motion was observed compared to normal subjects. The mean abduction angle decreased from 109° (±20) for normal subjects to 64° (±25). A similar trend was observed during flexion and axial rotation tasks. Furthermore, the normal group showed less variable ranges of motion performing the standard tasks, whereas for the prosthetic group this varied greatly, which is likely to be dependent on muscle strength. Although the decreased range of motion was prominent, subjects were able to complete most of the tasks by compensating with their elbow and trunk. The most challenging task for Bayley-Walker subjects was lifting an object to head height. Copyright © 2010 Elsevier B.V. All rights reserved.

    Full Text Available Cognitive impairment and psychiatric symptoms are common in patients with Cushing's disease (CD owing to elevated levels of glucocorticoids. Molecular neuroimaging methods may help to detect changes in the brain of patients with CD. The aim of this study was to investigate the characteristics of brain metabolism and its association with serum cortisol level in CD. We compared brain metabolism, as measured using [18F]-fluorodeoxyglucose positron emission tomography (FDG PET, between 92 patients with CD and 118 normal subjects on a voxel-wise basis. Pearson correlation was performed to evaluate the association between cerebral FDG uptake and serum cortisol level in patients with CD. We demonstrated that certain brain regions in patients with CD showed significantly increased FDG uptake, including the basal ganglia, anteromedial temporal lobe, thalamus, precentral cortex, and cerebellum. The clusters that demonstrated significantly decreased uptake were mainly located in the medial and lateral frontal cortex, superior and inferior parietal lobule, medial occipital cortex, and insular cortex. The metabolic rate of the majority of these regions was found to be significantly correlated with the serum cortisol level. Our findings may help to explain the underlying mechanisms of cognitive impairment and psychiatric symptoms in patients exposed to excessive glucocorticoids and evaluate the efficacy of treatments during follow-up.

    Objectives To study the prevalence of psychiatric comorbidity assessed by a structured clinical interview in patients with spasmodic dysphonia (SD) compared with patients suffering from vocal fold paralysis (VFP). Methods In 48 patients with SD and 27 patients with VFP, overall psychiatric comorbidity was studied prospectively using the Structured Clinical Interview for DSM‐IV Axis I disorders. Physical disability and psychometric variables were assessed with standardised self‐rating questionnaires. Results 41.7% of SD subjects and 19.5% of the control group met DSM‐IV clinical criteria for current psychiatric comorbidity (p<0.05). Significant predictors of psychiatric comorbidity in SD were severity of voice impairment and subjective assessment of “satisfaction with health”. As a limitation, the severity of voice impairment in patients with SD was nearly twice as high, and their illness had lasted nearly twice as long. Conclusions We found a high prevalence of psychiatric comorbidity in patients with SD. The significant correlation between current psychiatric comorbidity and the extent of voice pathology may point to an especially strong interaction between somatic and psychiatric complaints in SD.

    We used repetitive transcranial magnetic stimulation (rTMS) to further investigate motor cortex excitability in 13 patients with Becker muscular dystrophy (BMD), six of them with slight mental retardation. RTMS delivered at 5Hz frequency and suprathreshold intensity progressively increases the size of motor evoked potentials (MEPs) in healthy subjects; the rTMS-induced facilitation of MEPs was significantly reduced in the BMD patients mentally retarded or classified as borderline when compared with age-matched control subjects and the BMD patients with normal intelligence. The increase in the duration of the cortical silent period was similar in both patient groups and controls. These findings suggest an altered cortical short-term synaptic plasticity in glutamate-dependent excitatory circuits within the motor cortex in BMD patients with intellectual disabilities. RTMS studies may shed new light on the physiological mechanisms of cortical involvement in dystrophinopathies. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    A larger pituitary size is thought to reflect a greater activation of the hypothalamic-pituitary-adrenal (HPA) axis, which may be related to an increase in the number and size of corticotroph cells. Some studies, but not all, indicate that pituitary volume increases before or at the onset of psychosis. There is a need for at critical appraisal of the literature on this topic accompanied by a meta-analytical evaluation of the data. We included studies comparing the volume of the pituitary gland in healthy controls and patients with schizophrenia, first episode of psychosis (FEP), schizotypal disorder or ultra high-risk (UHR) subjects. We defined three groups of subjects for the analyses: healthy controls; UHR and schizotypal patients; and patients diagnosed with first episode of psychosis, schizophrenia or schizoaffective disorder. Ten studies were included in the meta-analysis. We found a trend of a larger pituitary volume in both UHR subject who had transition to psychosis (p=0.05) and in FEP subjects (p=0.09) compared to healthy controls. There was no difference in pituitary volume between patients with schizophrenia combined with FEP versus healthy controls (p=0.52) or between UHR (with and without transition) and healthy controls (p=0.24). In a regression analysis, we demonstrated that the number of subjects receiving antipsychotics and pituitary volume were positively correlated. As previously reported in other samples, gender also had an impact on pituitary volume with females presenting with a larger mean volume. Results from this meta-analysis suggest that the pituitary gland could be increasing before the onset of psychosis. Both gender and use of antipsychotics have a major impact on the pituitary volume.

    In the quest for prevention or treatment, there is a need to find early markers for preclinical dementia. This study observed memory clinic patients with subjective cognitive impairment (SCI) and normal cognitive function at baseline. The primary aim was to address SCI as a potential risk factor for cognitive decline. The secondary aim was to address a potential relation between (1) baseline cerebrospinal fluid biomarkers and (2) a decline in memory performance over the first 2 years of follow-up, with a possible cognitive decline after 6 years. Eighty-one patients (mean age 61 years) were recruited from university memory clinics and followed up for 6 years. Eighty-six percent of the cohort remained cognitively stable or improved, 9% developed mild cognitive impairment, and only 5% ( n = 4) developed dementia. Regression analysis revealed that low levels of Aβ 42 at baseline and memory decline during the first 2 years predicted dementia. When combined, these variables were associated with a 50% risk of developing dementia. Cognitive stability for 86% of the cohort suggests that SCI is predominantly a benign condition with regard to neuropathology. The low number of individuals who developed dementia limits the generalizability of the results and discussion of progression factors.

    Mathematics has always become the most dislike subject among other subjects in school. Study showed that attitudes of students in science subjects such as mathematics were closely related to how they solve problems, accessing ideas and making a right decision. According to another study on mathematics achievement of eighth grade students in Malaysia, mathematics grades among bumiputera students was lower when compared to other races such as Chinese and Indians. The poor performance was due to their attitude and pre-conceived ideas towards the subject. Therefore, this study was designed todetermine the criteria and subcriteria that were considered important in measuring students' attitude toward mathematics among the bumiputeras. Factor analysis was carried out to identify the groups among criterion. Instrument used to measure mathematics attitude was Test of Mathematics Related Attitude (TOMRA) which measured student attitudes in four criteria: normality of mathematics, attitudes towards mathematics inquiry, adoption of mathematics attitude and enjoyment of mathematics lessons. The target population of this study was all computer science and quantitative science students who enrolled Calculus subject in UiTM Kedah. Findings shows that there are two criteria that influenced students attitude toward mathematics namely normality of mathematics with eleven subcriteria and enjoyment of mathematics with eight subcriteria. From the analysis it shows that the total percentage of variation explained is 35.071% with 0.837 Cronbach's alpha reliability test. The findings will help the lecturers, parents and society to consider what action should be taken to install interest and positive attitude of bumiputera students towards mathematics and thus improve their achievement.

    Full Text Available Introduction: Tinnitus is a common complaint in patients referred to otorhinolaryngology clinics and is a condition where one hears a sound without any distinguishable external acoustic source or electrical stimulus. About 3-30% of adults experience different degrees of tinnitus during their life. This study aims to ascertain and compare personality traits between patients with tinnitus and a control group.   Materials and Methods: In a case control study, 66 participants were assessed. The case group consisted of 33 patients who suffered from tinnitus for at least two months, in addition to 33 healthy volunteers who were selected among their family (preferably of the same age and sex. A standard demographic questionnaire and an Eyzenck personality questionnaire were filled for both groups. A tinnitus severity index (TSI questionnaire was only filled for the case group. Data from each group was compared by Mann-Whitney U and Chi-Square tests. SPSS V.18 was the selected software.   Results: Statistical analysis showed a meaningful difference in neuroticism (P=0.001 and extraversion (P=0.001 between the patients and the controls; however, there was no statistical difference between these groups regarding psychotism.   Conclusion:  Tinnitus can be associated with personality characteristics. This study showed that in patients with tinnitus, neuroticism increases and extraversion decreases. Considering the personality and psychotic traits observed in the patients with tinnitus, psychiatric consultation is recommended.

    In this study we aimed to describe the magnetic resonance imaging (MRI) pattern of the distribution of bone marrow edema (BME) and joint erosion in hands and wrists of patients with systemic lupus erythematosus (SLE) with arthritis in comparison with rheumatoid arthritis (RA) and healthy subjects (H). SLE patients with arthritis (n = 50), patients with RA (n = 22), and H (n = 48) were enrolled. Every patient underwent a non-dominant hand (2nd-5th metacarpophalangeal joints) and wrist MRI without contrast injection with a low-field extremity dedicated 0.2-Tesla instrument. BME was observed in two SLE patients in the hand (4 %) and in 15 in the wrist (13 %) versus three (30 %), and 14 (63 %) RA patients. No BME was found in H. Erosions were observed in the hand in 24 SLE patients (48 %), 15 RA patients (68 %), and 9 H (18 %); in the wrist, in 41 (82 %) SLE, all RA and 47 (97 %) H. The cumulative erosive burden in SLE was significantly higher than in H (c = 0.002) but similar to RA patients. Joint involvement of the wrist in SLE is similar to RA and is not as rare as expected, as shown by the comparison with healthy subjects. On the contrary, the involvement of the hand in SLE is significantly lower compared to RA. (orig.)

    Subjective cognitive impairment (SCI), depressive symptoms, and fatigue are common after stroke and are associated with reduced quality of life. We prospectively investigated their prevalence and course after a transient ischemic attack (TIA) or nonfocal transient neurological attack (TNA) and the association with diffusion-weighted imaging (DWI) lesions. The Cognitive Failures Questionnaire, Hospital Anxiety and Depression Scale, and Subjective Fatigue subscale from the Checklist Individual Strength were used to assess subjective complaints shortly after TIA or TNA and six months later. With repeated measure analysis, the associations between DWI lesion presence or clinical diagnosis (TIA or TNA) and subjective complaints over time were determined. We included 103 patients (28 DWI positive). At baseline, SCI and fatigue were less severe in DWI positive than in DWI negative patients, whereas at follow-up, there were no differences. SCI ( p = 0.02) and fatigue ( p = 0.01) increased in severity only in DWI positive patients. There were no differences between TIA and TNA. Subjective complaints are highly prevalent in TIA and TNA patients. The short-term prognosis is not different between DWI-positive and DWI negative patients, but SCI and fatigue increase in severity within six months after the event when an initial DWI lesion is present.

    Full Text Available The purpose of this research was to study the cognitive functions in patients with methamphetamine-induced psychosis (MIP in comparison with schizophrenia patients and normal subjects.This was a cross-sectional study, 30 patients with MIP, 30 patients with schizophrenia and 30 normal individuals were selected via convenient sampling and were matched on age, sex and education. Wisconsin Cards Sorting, Stroop, Visual Search and Attention and Wechsler Memory Tests were used to assess the subjects.The study showed that patients with MIP and schizophrenia have more deficits in executive functions, selective attention, sustained attention and memory than normal subjects. There were no significant differences in cognitive functions between patients with MIP and schizophrenia except for visual search and attention that showed more impairment in patients with schizophrenia.Although, cognitive dysfunctions of patients with MIP are mostly similar to patients with schizophrenia, some differences seem to exist, especially in those functions that are not primarily dependent on frontal lobe.

    Objective To compare swallowing function between healthy subjects and patients with pharyngeal dysphagia using high resolution manometry (HRM) and to evaluate the usefulness of HRM for detecting pharyngeal dysphagia. Methods Seventy-five patients with dysphagia and 28 healthy subjects were included in this study. Diagnosis of dysphagia was confirmed by a videofluoroscopy. HRM was performed to measure pressure and timing information at the velopharynx (VP), tongue base (TB), and upper esophageal sphincter (UES). HRM parameters were compared between dysphagia and healthy groups. Optimal threshold values of significant HRM parameters for dysphagia were determined. Results VP maximal pressure, TB maximal pressure, UES relaxation duration, and UES resting pressure were lower in the dysphagia group than those in healthy group. UES minimal pressure was higher in dysphagia group than in the healthy group. Receiver operating characteristic (ROC) analyses were conducted to validate optimal threshold values for significant HRM parameters to identify patients with pharyngeal dysphagia. With maximal VP pressure at a threshold value of 144.0 mmHg, dysphagia was identified with 96.4% sensitivity and 74.7% specificity. With maximal TB pressure at a threshold value of 158.0 mmHg, dysphagia was identified with 96.4% sensitivity and 77.3% specificity. At a threshold value of 2.0 mmHg for UES minimal pressure, dysphagia was diagnosed at 74.7% sensitivity and 60.7% specificity. Lastly, UES relaxation duration of dysphagia. Conclusion We present evidence that HRM could be a useful evaluation tool for detecting pharyngeal dysphagia. PMID:29201816

    Full Text Available Abstract Background Intestinal mucosa is leaky in celiac disease (CD, and this alteration may involve changes in hydrophobicity of the mucus surface barrier in addition to alteration of the epithelial barrier. The aims of our study were i to compare duodenal hydrophobicity as an index of mucus barrier integrity in CD patients studied before (n = 38 and during gluten- free diet (GFD, n = 68, and in control subjects (n = 90, and ii to check for regional differences of hydrophobicity in the gastro-intestinal tract. Methods Hydrophobicity was assessed by measurement of contact angle (CA (Rame Hart 100/10 goniometer generated by a drop of water placed on intestinal mucosal biopsies. Results CA (mean ± SD of distal duodenum was significantly lower in CD patients (56° ± 10° than in control subjects (69° ± 9°, p corpus > rectum > duodenum > oesophagus > ileum. Conclusions We conclude that the hydrophobicity of duodenal mucous layer is reduced in CD patients, and that the resulting decreased capacity to repel luminal contents may contribute to the increased intestinal permeability of CD. This alteration mirrors the severity of the mucosal lesions and is not completely reverted by gluten-free diet. Intestinal hydrophobicity exhibits regional differences in the human intestinal tract.

    Full Text Available Abstract Background Patients with irritable bowel syndrome (IBS often relate symptoms to the intake of certain foods. This study assesses differences in diet in subjects with and without IBS. Methods The cross-sectional, population-based study was conducted in Norway in 2001. Out of 11078 invited subjects, 4621 completed a survey about abdominal complaints and intake of common food items. IBS and IBS subgroups were classified according to Rome II criteria. Results IBS was diagnosed in 388 subjects (8.4% and, of these, 26.5% had constipation-predominant IBS (C-IBS, 44.8% alternating IBS (A-IBS, and 28.6% diarrhoea-predominant IBS (D-IBS. Low intake of dairy products (portions/day (Odds Ratio 0.85 [CI 0.78 to 0.93], p = 0.001 and high intake of water (100 ml/day (1.08 [1.02 to 1.15], p = 0.002, tea (1.05 [1.01 to 1.10], p = 0.019 and carbonated beverages (1.07 [1.01 to 1.14], p = 0.023 were associated with IBS. A lower intake of dairy products and a higher intake of alcohol and carbonated beverages were associated with D-IBS and a higher intake of water and tea was associated with A-IBS. In subjects with IBS the severity of symptoms was associated with a higher intake of vegetables and potatoes in subjects with C-IBS, with a higher intake of vegetables in subjects with A-IBS, and with a higher intake of fruits and berries, carbonated beverages and alcohol in subjects with D-IBS. Conclusions In this study, the diet differed in subjects with and without IBS and between IBS subgroups and was associated with the severity of symptoms.

    Low vitamin D levels have been associated with several autoimmune diseases. Vitiligo could be associated with low vitamin D levels. To determine the level of serum vitamin D in vitiligo patients compared to controls and reveal the possible association of vitamin levels with the pathogenesis of vitiligo. A case-controlled study was conducted. After excluding factors that may affect serum vitamin D levels, blood samples were taken from vitiligo patients and controls. The association between vitamin D levels and various vitiligo subgroups (duration of vitiligo, site of onset, age, etc) was measured and correlated. A total of 150 vitiligo patients, 90 (60%) males with a mean age of 30.6 ± 11.4 years, were recruited. The study also had 150 age- and gender-matched vitiligo-free control subjects. There was no significant difference in median serum vitamin D levels between the cases and the controls (P = .25). The serum levels of vitamin D of the vitiligo patients were found to be lower in males (P = .01), the younger age group (P = .01), and patients not treated with ultraviolet (UV) treatment (P = .01). There is no difference between the vitamin D levels of the vitiligo patients and the control subjects. However, deficiency of 25(OH)D levels within the vitiligo subgroups may be linked to younger age, male gender, short duration of vitiligo, and non-use of phototherapy. © The Author(s) 2015.

    To assess the quality of life in glaucoma patients and normal subjects, and to assess its relationship with the severity of damage in each eye. A cross-sectional study was conducted with prospective selection of cases. The study included 464 subjects and were distributed into 4categories. Subjects included in group 1 had both eyes normal, that is with a normal intraocular pressure (IOP), optic disk and visual fields (VF), or mild glaucoma, defined as untreated IOP>21mmHg and abnormal VF with mean defect (MD) over -6dB. Group 2 consisted of patients with both eyes with mild or moderate glaucoma, defined as untreated IOP>21mmHg and abnormal VF with MD between -6 and -12dB. Group 3 included patients with moderate to severe glaucoma, that is, untreated IOP>21mmHg and abnormal VF with MD of less than -12dB in both eyes. Group 4 consisted of patients with asymmetric glaucoma damage, that is, they had one eye with severe glaucoma and the other eye normal or with mild glaucoma. All subjects completed 3 different questionnaires. Global quality of life was evaluated with EuroQol-5D (EQ-5D). Vision related quality of life was assessed with Visual Function Questionnaire (VFQ-25). Quality of life related to ocular surface disease was measured with Ocular Surface Disease Index (OSDI). VFQ-25 showed that group 3 had significantly lower scores than group 1 in mental health (P=.006), dependence (P=.006), colour vision (P=.002), and peripheral vision (P=.002). EQ-5D showed no significant differences between any group, but a trend was found to greater difficulty in group 3 than in groups 1 and 2, and in all dimensions. OSDI showed a higher score, or which was the same as a major disability, in groups 2 and 3 than group 1 (P=.021 and P=.014, respectively). VFQ-25 only found significant differences between group 1 and group 4. Dimensions with significant differences were found between group 1 and 3 (both eyes with advanced or moderate glaucoma). These were not found between group 1 and

    To estimate rates of ovarian aging in polycystic ovary syndrome (PCOS) subjects versus a community control population. Longitudinal. Tertiary academic center. PCOS subjects diagnosed according to the 2004 Rotterdam criteria were systematically enrolled in a PCOS cohort study. The comparison control subjects were from the Ovarian Aging study, a prospective longitudinal study of ovarian aging in healthy women with regular menstrual cycles. Clinical data collection over two study visits. Antral follicle count (AFC), ovarian volume (OV), and antimüllerian hormone level (AMH). PCOS subjects were found to have higher baseline values for all ovarian reserve markers compared with control subjects. Univariate models indicated that, compared with control subjects, PCOS patients experienced significantly faster rates of decline for both AFC and AMH. Change in OV did not differ significantly. To account for potential confounder effects, multiple analysis of covariance models were evaluated for the best fit, considering age, body mass index, and baseline ovarian reserve markers. Adjusted models demonstrated that PCOS patients do not experience a significant difference in AFC decline compared with control subjects, but they do experience a faster rate of decline in AMH (POvarian aging in PCOS is characterized by a more rapid decline in AMH and a slower decline in OV compared with control subjects.

    The proprioceptive sensitivity of healthy volunteers and convalescents after acute cerebrovascular episodes was studied by a new neurophysiological method for registration of kinesthetic evoked potentials emerging in response to passive 50(o) bending of the hand in the wrist joint with the angular acceleration of 350 rad/sec(2). Kinesthetic evoked potentials were recorded above the somatosensory cortex projection areas in the hemispheres contra- and ipsilateral to the stimulated limb. The patients exhibited significantly longer latencies and lesser amplitudes of the early components of response in the involved hemisphere in comparison with normal subjects. The method for registration of the kinesthetic evoked potentials allows a more detailed study of the mechanisms of kinesthetic sensitivity in health and in organic involvement of the brain.

  19. B-cell depletion is protective against anti-AAV capsid immune response: a human subject case study

    2014-01-01

    Full Text Available Gene therapy strategies for congenital myopathies may require repeat administration of adeno-associated viral (AAV vectors due to aspects of the clinical application, such as: (i administration of doses below therapeutic efficacy in patients enrolled in early phase clinical trials; (ii progressive reduction of the therapeutic gene expression over time as a result of increasing muscle mass in patients treated at a young age; and (iii a possibly faster depletion of pathogenic myofibers in this patient population. Immune response triggered by the first vector administration, and to subsequent doses, represents a major obstacle for successful gene transfer in young patients. Anti-capsid and anti-transgene product related humoral and cell-mediated responses have been previously observed in all preclinical models and human subjects who received gene therapy or enzyme replacement therapy (ERT for congenital myopathies. Immune responses may result in reduced efficacy of the gene transfer over time and/or may preclude for the possibility of re-administration of the same vector. In this study, we evaluated the immune response of a Pompe patient dosed with an AAV1-GAA vector after receiving Rituximab and Sirolimus to modulate reactions against ERT. A key finding of this single subject case report is the observation that B-cell ablation with rituximab prior to AAV vector exposure results in non-responsiveness to both capsid and transgene, therefore allowing the possibility of repeat administration in the future. This observation is significant for future gene therapy studies and establishes a clinically relevant approach to blocking immune responses to AAV vectors.

    Full Text Available Background: Lack of clinical tests to quantify spatial components of distortion in patients with full thickness macular holes (FTMH and epiretinal membranes (ERM. Aim: To develop a test for subjective evaluation of visual distortion in the central visual field around fixation in patients with unilateral FTMH or ERM. Settings and Design: Prospective case-control study carried out at tertiary referral center. Materials and Methods: Twenty-five patients with unilateral macular disease (13 macular epiretinal membranes, 12 full-thickness macular holes, and nine controls (without ocular pathology underwent ophthalmological examination with logMAR ETDRS visual acuity, near vision and contrast sensitivity assessed. Macular optical coherence tomography and metamorphopsia assessment using Morphision test was also carried out. This test consists of a set of modified Amsler charts for detection, identification, and subjective quantification of visual distortion in the central visual field around fixation. Morphision test content and construct validity, and reliability (test-retest method were evaluated. Sixteen patients completed an unstructured survey on test performance and preference. Results: Every patient with unilateral FTMH or ERM identified a particular chart using Morphision test (content validity. None of the normal subjects without symptoms of metamorphopsia identified any distortion (construct validity. Test-retest showed a 100% consistency for frequency and 67% for amplitude. The mean amplitude difference between measurements was 0.02 degrees (SD = 0.038. The coefficient of repeatability was 0.075. There was a correlation between Morphision amplitude score and visual acuity and contrast sensitivity, individually. Conclusions: Morphision test allowed detection and subjective quantification of metamorphopsia in the clinical setting in our patients with unilateral macular epiretinal membranes and full thickness macular holes.

    An important aspect of the study of brain function involves measurement of the relationships; between activities in the subcortical gray matter of the caudate and of the thalamus; and between these structures and functional cortical areas. The authors have studied these relationships in 22 subjects under different conditions of activation, sleep and sensory deprivation using a PET VI system and F-18-2DG to determine regional cerebral metabolism. Subject activating conditions were maintained throughout the period of equilibration of F-18-2DG and E.E.G.'s were monitored. Multiple tomographic slices of 1-2 million counts were obtained simultaneously with slice separation of 14mm and each plane parallel to the cantho-meatal line. In activated and non-activated awake conditions for normal subjects, left and right thalmus-to-caudate ratios were similar and greater than unity. This relationship was maintained in non-REM sleep, but was reversed and divergent in REM sleep and sensory deprivation; this was also evident in 3/4 narcoleptics awake and asleep in non-REM and REM and 2/3 schizophrenics and affective disorder, subjects. This approach appears to have potential for characterizating normal and disordered regional cerebral function

    The absence of classical symptoms and signs of hyperthyroidism often results in delayed diagnosis and treatment. The objective of the study was to determine the prevalence of symptoms and signs of hyperthyroidism according to patients' age and gender as well as severity and type of hyperthyroidism. This was a cross-sectional study of 3049 consecutive patients with hyperthyroidism presenting to a single secondary/tertiary care clinic. Calculation of adjusted odds ratios for presence/absence of symptoms/signs of hyperthyroidism simultaneously analyzing the influence of patients' age/gender, disease etiology/severity, symptom duration, and smoking. The majority of patients older than 61 yr had two or more symptoms. The lowest proportion of subjects reporting five or more symptoms was found in those older than 61 yr. Increasing age was associated with reduced adjusted odds ratio for the presence of most classical symptoms except for weight loss and shortness of breath, independent of disease severity. Those with more severe hyperthyroidism and smokers had increased odds ratios for most symptoms. Older age, higher serum free T(4) concentrations at diagnosis, male gender, and toxic nodular hyperthyroidism were independently associated with risk of atrial fibrillation. Signs of ophthalmopathy were associated with increasing age, smoking, longer symptom duration, and female gender. Classical symptoms and signs of hyperthyroidism are significantly less prevalent in older patients and more prevalent in smokers and subjects with higher free T(4) concentrations. We propose a lower threshold for performing thyroid function tests in patients older than 60 yr, especially in those presenting with atrial fibrillation, weight loss, or shortness of breath.

    Thalassemic patients are vulnerable to emotional and behavioral problems. Each patient age group exhibits problems unique to that stage of development, and although up to 80 % of thalassemic patients are likely to have psychological disorders, e.g., anxiety and depression, predictors of these disorders remain poorly understood. The present study was designed to assess the prevalence of anxiety and depression in a sample of Egyptian thalassemic patients and to identify predictors of these psychiatric disorders. A case-control study was conducted in 218 thalassemic patients, with 244 healthy subjects as a control. All patients and control subjects were subjected to thorough evaluation of medical history and clinical examination, and examined by a psychiatrist using the clinician version of the structured clinical interview for DSM-IV (SCID-CV), hospital anxiety and depression scale and Coopersmith self-esteem inventory. Abnormal and borderline anxieties were reported by 36.7 and 20.6 % of thalassemic patients, respectively, while abnormal and borderline depressions were reported by 32.1 and 16.1 % of patients, respectively. Hospitalization, low self-esteem, diabetes mellitus and heart failure were independent predictors of anxiety. The independent predictors of depression were heart failure, hospitalization, diabetes mellitus, short stature and delayed puberty. Thalassemic patients were more vulnerable to anxiety and depression, indicating that screening and management for such psychiatric disorders should be considered in treating all such patients.

    Objective: To evaluate the serological profile of patients with incidentally detected positive hepatitis-B surface antigen (HBsAg) and to asses the risk factors. Design: An observational study. Place and Duration of Study: This study was conducted at Shifa International Hospital, Islamabad from 1999 to 2003. Patients and Methods: All patients who presented to gastroenterology clinic of Shifa Intentional Hospital, Islamabad with positive HBsAg, detected incidentally, were tested for alamine transaminase (ALT), hepatitis Beantigen (HBeAg) and in certain cases hepatitis-B virus DNA (HBV DNA) by polymerase chain reaction (PCR). Their risk factors for acquisition of infection were assessed with specific questions. Results: A total of 224 patients were examined. One hundred sixty-four (73.2%) were male and 60 (26.8%) female. Mean age of all the subjects was 32.45 plus minus 11.85 years. Out of 224 patients, 48 (21.4%) were positive for HBeAg and 176 (78.6%) were negative. Out of 48 subjects who were positive for HBeAg, 36 underwent HBV DNA determination and 32 (88.8%) were positive for HBV DNA. Out of 176 subjects who had negative HBeAg, 46 had elevated ALT and in those HBV DNA was performed and 14 had positive HBV DNA. Most common risk factors detected in these patients were intramuscular injections and surgery, however, in a large number, risk factors were unknown. Conclusion: Twenty-one percent asymptomatic subjects with positive HBsAg were found to be HBeAg positive. A large number of subjects with negative HBeAg had HBV DNA positive suggesting presence of precore mutants. Intramuscular injections and surgery were noted to be frequent risk factors in these subjects. (author)

    Objectives: To evaluate the presence of blood flow by colour Doppler ultrasonography (CDUS) in the wrist and finger joints of rheumatoid arthritis (RA) patients and healthy subjects and to define a cut-off value of CDUS resistive index (RI). Methods: Forty-three patients with RA and 43 healthy controls were examined by CDUS. The wrists, second and third metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints were evaluated in each patient and healthy subject. Spectral Doppler analysis was performed in order to characterize the type of flow and a mean RI was measured to define a cut-off level. The area under receiver operating characteristic curve was used to evaluate the screening method's performance. Results: Flow was detected in 219 of the 430 total joints (50.9%) of RA patients (111 in the wrists, 49 in the MCP and 30 in the PIP joints). Healthy subjects had a quantifiable flow in 45 of the 430 joints (10.5%) and, in particular, 39 (86.4%) in the wrist, 5 (11.14%) in the MCP and 1 (2.2%) in the PIP joints. The intra- and inter-reader agreements for the detection of Doppler signal were very good (kappa 0.82 and 0.89, respectively). Mean RI values were 0.72 {+-} 0.06 in RA patients and 0.86 {+-} 0.06 in healthy subjects (p < 0.01). At cut-off point of RI < 0.79 the sensitivity was 89.6% and the specificity was 78.8% (positive likelihood ratio 4.22). Conclusion: DUS is a useful tool for the detection of abnormal blood flow in inflammatory joints of RA patients.

    Longitudinal studies on healthy participants have shown that subjective memory impairment (defined as subjective cognitive complaints with normal cognitive objective performance) might be a strong predictor of mild cognitive impairment (MCI). Parkinson disease (PD) also manifests cognitive disturbances, but whether subjective memory complaints may predict the development of MCI in PD has not yet been explored. We prospectively screened newly diagnosed, untreated patients with PD in order to evaluate whether subjective memory complaints may predict development of MCI over a 2-year follow-up evaluation. We enrolled 76 de novo untreated patients with PD. Of the 76 patients, 23 (30.3%) complained memory issues. Among the patients cognitively unimpaired at baseline, those with subjective complaints were more likely to develop MCI at follow-up. The regression model confirmed that presence of subjective memory complaints at baseline was an independent predictor of development of MCI at follow-up. This is the first prospective study to explore the relationship between subjective and objective cognitive deficits in newly diagnosed, untreated patients. Our results provide preliminary evidence that subjective memory complaints might predict future development of MCI. © The Author(s) 2014.

    Between 1970 and 1974 a saturation analysis for cortisol in plasma and free cortisol in urine, and a radioimmunoassay method for aldosterone in plasma and urine were developed. In order to permit a comparative evaluation it was necessary to study corticosteroids, diurnal rhythm and the probable effect of a siesta on this rhythm both in normal subjects and in patients suffering from hemic diseases, in particular from sickle-cell anemia. Saturation assay for cortisol, using serum from pregnant women as source of transcortin, and radioimmunoassay for aldosterone were the basic methods used. Serum cortisol was estimated twice a day (8-9 a.m. and 5-6 p.m.). Cortisol and aldosterone were also estimated in serum and in urine before and after adrenalin stimulation with ACTH. No significant influence of a siesta on the diurnal rhythm of cortisol was observed, nor did the levels of serum cortisol or the diurnal rhythm appear affected in congenital hemolytic anemias, following adrenalin stimulation. The report lists experimental results briefly and refers to a paper in which these are published in more detail

In six normal subjects, angiotensin infusion decreased heart rate (HR) from 72 +/- SEM 2 to 57 +/- 2 beats/min (P less than 0.001); while systolic blood pressure (BP) increased from 119 +/- 2 to 178 +/- 1 mm Hg (P less than 0.001), and ejection fraction (EF) declined from 58 +/- 1 to 47 +/- 2 percent (P less than 0.05). In contrast, in 11 normal subjects, supine exercise increased HR and systolic BP by 55 and 49 percent, whereas EF increased from 64 +/- 1 to 71 +/- 1 (P less than 0.001). In ten patients with CAD, angiotensin infusion produced no change in HR, increased systolic BP by 34 percent, and decreased EF by 11 percent. Angiotensin infusion induced left ventricular depression in normal subjects and in patients with CAD. It cannot substitute for exercise in intervention radionuclide ventriculography.

    To assess the clinical characteristics and changes in ocular surface cytology of dry eye in patients with systemic autoimmune disease. The case-control study was conducted in the Second Hospital of Tianjin Medical University, Tianjin, China, from February 2016 to January 2017, and comprised systemic autoimmune disease patients and healthy controls. Schirmer's I test, tear breakup time test, and fluorescein staining were performed on all subjects. Both groups were evaluated for dry eye with the current diagnostic criteria. Conjunctival impression cytology and the morphology of epithelial cells were observed in both groups of subjects. Flow cytometry was used to identify the amount of apoptosis. SPSS 15 was used to analyse the data. Each of the two groups had 60(50%) subjects each. The morbidity of dry eye in the control group was 17(28.3%), while it was 31(51.7%) in the patients (pdry eye, the severity level of cells obtained by conjunctival impression sampling was significantly higher in patients than in controls (pdry eye than in patients without dry eye in each group, and among patients with dry eye, the percentage of conjunctival epithelial cells undergoing apoptosis was higher in the patients than in controls (pdry eye in systemic autoimmune disease than in subjects with dry eye in healthy controls.

    The relationship between the subjective skin type and the casual sebum level was not fully clarified. To investigate the characteristics of subjective skin type and to find the relationship between the subjective skin types and the skin type-related symptoms, casual sebum level, along with the objective skin type. Seven hundred and nine patients, clinically diagnosed with acne, were included. The questionnaire and the casual sebum level measurement were performed. The determining symptoms of each subjective skin type were investigated. The 95% confidence interval of casual sebum level of each subjective skin type was calculated. The most frequent subjective skin type was the combination type. The dryness, tightness, and oiliness can be conclusive symptoms in determining the subjective skin type. The mean and the 95% confidence interval of the casual sebum level was highest in the oily skin type, followed by the combination, normal, and dry skin type. We found that the subjective skin type was determined by the skin type-related symptoms. The 95% confidence intervals of the casual sebum level of each subjective skin type were established. Based on the skin type-related symptoms, the casual sebum level of acne patients can be estimated. © 2012 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    Full Text Available Several omics technologies are underway worldwide with an aim to unravel the pathophysiology of a complex phenotype such as type 2 diabetes mellitus (T2DM. While recent studies imply a clinically relevant and potential biomarker role of circulatory miRNAs in the etiology of T2DM, there is lack of data on this aspect in Indians--an ethnic population characterized to represent 'Asian Indian phenotype' known to be more prone to develop T2DM and cardiovascular disease than Europeans. We performed global serum miRNA profiling and the validation of candidate miRNAs by qRT-PCR in a cohort of subjects comprised of normal glucose tolerance (NGT, impaired glucose tolerance (IGT and patients with T2DM. Our study revealed 4 differentially expressed miRNAs (miR-128, miR-130b-3p, miR-374a-5p, miR-423-5p in subjects with IGT and T2DM patients compared to control subjects. They were positively or negatively correlated to cholesterol levels, HbA1C, HOMA-IR and fasting insulin. Interestingly, circulating level of miR-128 and miR-130b-3p were also altered in serum of diet-induced diabetic mice compared to control animals. Among the altered circulating miRNAs, miR-128 had never been described in previous studies/populations and appeared to be a 'New Lead' in Indians. It was positively correlated with cholesterol both in prediabetic subjects and in diet-induced diabetic mice, suggesting that its increased level might be associated with the development of dyslipedemia associated with T2DM. Our findings imply directionality towards biomarker potential of miRNAs in the prevention/diagnosis/treatment outcomes of diabetes.

    Full Text Available Untreated unilateral developmental dysplasia of the hip (DDH results in asymmetry of gait and hip strength and may lead to early osteoarthritis, which is commonly treated with a total hip arthroplasty (THA. There is limited knowledge about the obtained symmetry of gait and hip strength after the THA. The objectives of this cross-sectional study were to: a identify asymmetries between the operated and non-operated side in kinematics, kinetics and hip strength, b analyze if increased walking speed changed the level of asymmetry in patients c compare these results with those of healthy subjects.Women (18-70 year with unilateral DDH who had undergone unilateral THA were eligible for inclusion. Vicon gait analysis system was used to collect frontal and sagittal plane kinematic and kinetic parameters of the hip joint, pelvis and trunk during walking at comfortable walking speed and increased walking speed. Furthermore, hip abductor and extensor muscle strength was measured.Six patients and eight healthy subjects were included. In the patients, modest asymmetries in lower limb kinematics and kinetics were present during gait, but trunk lateral flexion asymmetry was evident. Patients' trunk lateral flexion also differed compared to healthy subjects. Walking speed did not significantly influence the level of asymmetry. The hip abduction strength asymmetry of 23% was not statistically significant, but the muscle strength of both sides were significantly weaker than those of healthy subjects.In patients with a DDH treated with an IBG THA modest asymmetries in gait kinematics and kinetics were present, with the exception of a substantial asymmetry of the trunk lateral flexion. Increased walking speed did not result in increased asymmetries in gait kinematics and kinetics. Hip muscle strength was symmetrical in patients, but significantly weaker than in healthy subjects. Trunk kinematics should be included as an outcome measure to assess the biomechanical

    The seroepidemiology of Leptospira infection in patients suffering from liver disease has been poorly studied. Information about risk factors associated with infection in liver disease patients may help in the optimal planning of preventive measures. We sought to determine the association of Leptospira IgG seroprevalence and patients with liver diseases, and to determine the characteristics of the patients with Leptospira exposure. We performed a case-control study of 75 patients suffering from liver diseases and 150 age- and gender-matched control subjects. Diagnoses of liver disease included liver cirrhosis, steatosis, chronic hepatitis, acute hepatitis, and amoebic liver abscess. Sera of participants were analyzed for the presence of anti- Leptospira IgG antibodies using a commercially available enzyme immunoassay. Anti-Leptospira IgG antibodies were found in 17 (22.7%) of 75 patients and in 15 (10.0%) of 150 control subjects (OR = 2.32; 95% CI: 1.09-4.94; P=0.03). This is the first age- and gender-matched case control study about Leptospira seroprevalence in patients with liver diseases. Results indicate that Leptospira infection is associated with chronic and acute liver diseases. Results warrants for additional studies on the role of Leptospira exposure in chronic liver disease.

    Full Text Available The purpose of the present study was to compare Serbian and Japanese participants in their subjective experience of Serbian and Japanese architectural objects. Subjective experience was operationalized through the ratings on the bipolar scales (e.g. pleasant-unpleasant. In the Preliminary study 1, a set of twelve rating scales was generated. In the Preliminary study 2 twelve Serbian and twelve Japanese architectural objects were specified. In the main experiment two groups of participants, twenty-one Serbian and twenty Japanese, rated twelve Serbian and twelve Japanese objects. A factor analysis extracted three dimensions of subjective experience: Beauty, Firmness and Fullness. Analysis of variance have shown that both Serbian and Japanese participants agreed that Japanese architectural objects looked more beautiful and firmer than Serbian objects. These finding is generally in line with perceptualist hypothesis that stimulus constraints are more effective than culture. However, interactions revealed some cultural differences that are consistent with culturalist hypothesis: compared to Serbian participants, Japanese participants rated Japanese architectural objects as more beautiful, whereas, compared to Japanese, Serbian participants rated Serbian objects as less fragile and emptier than Japanese objects. Generaly, our study have shown that Serbian (Western and Japanese (Eastern participants show general similarity in their subjective experience of architectural objects.

Of these, 11 were girls (M: F: 1.6:1. Detailed anatomy could be studied in nine patients, were included in this study. Age of presentation in female subjects ranged 1 day to 8 years. On examination, eight of the nine patients had single perineal opening suggesting a very high incidence of association of cloaca in female subjects with CPC. Four had short urogenital sinus with colonic pouch opening in the posterior wall of urinary bladder. In other two patients, CPC terminated in short cloaca. Anomalies of mullerian structures such as uterus didelphus and septate vagina ware commonly encountered. Proximal diversion with or without pouch excision was done as the initial preliminary treatment for all those patients who presented in early life. Of the nine girls, two died after the preliminary surgery. Only five patients have undergone definitive surgery. Definitive surgery included abdomino-perineal pull-through of proximal normal colon ( n =2, tubularization of pouch with abdomino- posterior sagittal- pull through ( n =2 and abdomino-posterior sagittal urethra-vaginoanorectoplasty with pull through of tapered pouch colon in one patient. Two of these patients had concomitant bowel vaginoplasty. Three patients with tubularized pouches had constipation and spurious diarrhea. However, good pseudo-continence of bowel was achieved on regular bowel washes. The cosmetic appearance of perineum in all these three patients was acceptable. The patients in whom pouch excision was done had diarrhea and severe perineal excoriation resistant to conservative management.

    Case reports of cardiac arrest in temporal proximity to Conducted Electrical Weapon(CEW) exposure raise legitimate concerns about this as a rare possibility. In this pilot study, we respectfully navigate the oversight and regulatory hurdles and demonstrate the intra-shock electrocardiographic effects of an intentional transcardiac CEW discharge using subcutaneous probes placed directly across the precordium of patients with a previously implanted intracardiac EKG sensing lead. Adults scheduled to undergo diagnostic EP studies or replacement of an implanted cardiac device were enrolled. Sterile subcutaneous electrodes were placed at the right sternoclavicular junction and the left lower costal margin at the midclavicular line. A standard police issue TASER Model X26 CEW was attached to the subcutaneous electrodes and a 5 s discharge was delivered. Continuous surface and intracardiac EKG monitoring was performed. A total of 157 subjects were reviewed for possible inclusion and 21 were interviewed. Among these, 4 subjects agreed and completed the study protocol. All subjects tolerated the 5 s CEW discharge without clinical complications. There were no significant changes in mean heart rate or blood pressure. Interrogation of the devices after CEW discharge revealed no ventricular pacing, dysrhythmias, damage or interference with the implanted devices. In this pilot study, we have successfully navigated the regulatory hurdles and demonstrated the feasibility of performing intracardiac EKG recording during intentional precordial CEW discharges in humans. While no CEW-associated dysrhythmias were noted, the size of this preliminary dataset precludes making conclusions about the risk of such events. Larger studies are warranted and should consider exploring variations of the CEW electrode position in relation to the cardiac silhouette. Copyright © 2017. Published by Elsevier Ltd.

    This study was designed to compare inorganic salivary calcium, phosphate, flow rate and pH of un-stimulated saliva and oral hygiene of healthy subjects, patients with periodontitis and dental caries and to correlate salivary calcium level with the number of intact teeth. The present study consisted of 90 patients aged between 18 and 55 years and were divided into three groups, periodontitis, dental caries and controls. Oral hygiene index-simplified, probing pocket depth, clinical attachment level and number of teeth present, teeth with active carious lesions were recorded. Salivary flow rate and pH was recorded and subjected to biochemical investigation. Estimation of inorganic calcium and phosphate was performed by colorimetric method. Results showed statistically significant increase in salivary inorganic calcium and phosphate levels, poor oral hygiene status, pH and salivary flow rate in patients with periodontitis when compared with dental caries group and controls. Individuals who have increased salivary inorganic calcium, phosphate, pH, flow rate and maintain poor oral hygiene could be at a higher risk for developing periodontitis and may have less dental caries and more number of intact teeth.

    Subjective health status is an increasingly important parameter to assess the effect of percutaneous coronary intervention (PCI) in clinical practice. Aim of this study was to determine medical and psychosocial predictors of poor subjective health status over a 10 years' post-PCI period. We included a series of consecutive PCI patients (n = 573) as part of the RESEARCH registry, a Dutch single-center retrospective cohort study. These patients completed the 36-item Short-Form Health Survey (SF-36) at baseline and 10 years post-PCI. We found 6 predictors of poor subjective health status 10 years post-PCI: SF-36 at baseline, age, previous PCI, obesity, acute myocardial infarction as indication for PCI, and diabetes mellitus (arranged from most to least numbers of sub domains). SF-36 scores at baseline, age, and previous PCI were significant predictors of subjective health status 10 years post-PCI. Specifically, the SF-36 score at baseline was an important predictor. Thus assessment of subjective health status at baseline is useful as an indicator to predict long-term subjective health status. Subjective health status becomes better by optimal medical treatment, cardiac rehabilitation and psychosocial support. This is the first study determining predictors of subjective health status 10 years post-PCI.

    An attempt was made to affect immunologic reactions in infectious-allergic asthma patients by subjecting them to transcerebral exposure to UHF electric field. Seventy-six patients, aged 23 to 69 years with varying duration of the disease, were studied. The treatment consisted of 25 exposures lasting from 5 to 15 min; a sham exposure was used on ten patients serving as controls. In all, 55/66 patients experienced clinical improvement lasting 6 to 12 months; only 2/10 control patients had any improvement. After the exposure, the level of T-lymphocytes increased along with blood histamine level; no significant changes were observed in case of B-lymphocytes. This immunologic correction was most effective in patients with atopy, with decreased levels of T-lymphocytes and elevated levels of B-lymphocytes. 12 references.

    Full Text Available The complaints regarding sleep problems have not been well identified after a stroke. The aim of this study was to investigate the predictive factors of sleep quality and insomnia complaints in patients with stroke. A total of 70 subjects, 40 patients (57 ± 7 years and 30 healthy controls (52 ± 6 years assessed by the Pittsburgh Sleep Quality Index (PSQI and the Sleep Habits Questionnaire took part in the study. The data were analyzed using the chi-square test, the Student's t-test and logistic regression analysis. On average, the patients showed poor sleep quality (patients: 6.3 ± 3.5; controls: 3.9 ± 2.2; p= 0.002 and insomnia complaint was the most prevalent (patients: 37.5%; controls: 6.7%; p= 0.007. The absence of insomnia complaint (OR= 0.120; 95%CI= 0.017-0.873; p= 0.036 and the decreased latency of sleep (OR= 0.120; 95%CI= 0.017-0.873; p= 0.036 were the protective factors of sleep quality. Female sex (OR= 11.098; 95%CI= 1.167-105.559; p= 0.036 and fragmented sleep (OR= 32.040; 95%CI= 3.236-317.261; p= 0.003 were the risk factors for insomnia complaint. We suggest that complaints of poor sleep quality and insomnia should be given priority assessment during clinical diagnosis of sleep disorders in stroke.

    This is a description of a computerized tomographic study of 45 non-delusional depressed, 29 delusional depressed patients and 77 neurotic control subjects. The cerebral atrophy ratio (CAR) on the three different slices and the ventricular ratio (VBR) of the anterior horn and the body of the lateral ventricles were calculated, analyzed and compared using Student's t test. Compared to the control subjects, the non-delusional depressive patients had greater CAR values than the controls but there were no significant differences of VBR values between the two groups. The patients with delusional depression had significantly larger CAR and VBR values than the non-delusional depressives and control subjects. The delusional depressives had greater brain atrophy than the non-delusionals and it was suggested that organic cerebral factors may have etiological significance in the depressions, especially the delusional depressives.

    Permanently recalled drugs are a public health concern if they remain accessible in violation of applicable regulation. Illicit online pharmacies act as an alternative form of access and have been associated with the sale to patients of counterfeit/falsified/fraudulent/substandard drugs. We wished to determine if permanently recalled and significantly restricted drugs were illegally marketed for sale online. The study was conducted in two phases with two objectives. The first phase attempted to identify drugs subject to permanent recall in certain major pharmaceutical markets as well as those listed as recalled or significantly restricted by the United Nations. We also examined the market authorization status of identified drugs in China and India. The second phase used structured searches on the Internet to determine if identified drugs were marketed for sale online. The World Wide Web. After identification of permanently recalled and restricted drugs we conducted Internet searches for illegal "no prescription" marketing events. We assessed the form of marketing, whether a site offered direct-to-patient sale, use of social media marketing, and the site's compliance status with external monitoring bodies. Number of recalled drugs marketed as available for purchase on the Internet. We identified 16 class I equivalent permanently recalled or restricted drugs, 56.3 % (n = 9) of which maintained market authorization in either China or India. Half (n = 8) were marketed for sale online without a prescription direct-to-patient. Use of social media marketing was mixed, with only 18.8 % (n = 3) of recalled drugs having a presence on Facebook, though 50.0 % (n = 8) had content on Twitter. We also found the majority (68.8 %, n = 11) were available and marketed for sale by vendors on the wholesale/business-to-business website alibaba.com primarily as active pharmaceutical ingredient. Despite efforts in several countries to restrict access to these drugs or permanently remove

    The Bristol Stool Chart (BSC) allows patients to identify their stool form using seven different images with accompanying written descriptors. Stool form was found to correlate better than stool frequency with whole-gut transit as measured by a radio-opaque marker study. This score is widely used in order to verify the presence of a constipation and to evaluate the therapeutic impact of various treatments. In our clinical practice, we was strongly surprised by the facility and the great precision of the patients to report their stool form, meaning that they usually and daily verify these stools. We wanted to precise the goals of a such attitude. Two questionnaires were proposed to healthy and voluntary subjects. Q1 was supposedly presented in order to verify the sensibility of a French version of BSC in a healthy population. Thus, Q1 precised the difficulties or not to understand pictures and written descriptors, asked about exhaustive analysis by means of BSC of stool form and bowel condition. All subjects with history of ano-rectal disorders or specific treatment for bowel dysfunction were excluded. After Q1 fulfilled, Q2 was proposed to the subjects. Q2 was designed to precise the goals of the patient when he look at his stool and the frequency of such an investigation. Finally a specific question concerning the subject opinion about this behavior in terms of bothersome, shame, or metaphysic interrogation. Eighty-five healthy subjects were recruited (42 female and 43 male). Mean age was 37.2 (sd = 15.7). Mean score of BCS was 2.07 (sd =1.05) (2.07 for female and 1.81 for male, P = 0.22). Number of categories of stool form was only 1 in 40%, 2 categories in 31%, 3 in 19%, 4 in 10%. Presence of a constipation defined by category 1 or 2 was found in 17% (23% in F, 12% in M, P = 0.075). Precision of BSC was noted as excellent in 68%, moderated in 18% and poor in 14%. BSC was considered as easy to use in 75%. Frequency of inspection of feces was systematic for 37%, 1

    The diabetic foot syndrome (DFS) is a serious complication in patients with diabetes increasing the risk for minor/major amputations. This analysis aimed to examine differences in diabetes patients with or without DFS stratified by type 1 (T1D) or type 2 diabetes (T2D). Adult patients (≥20y of age) with diabetes from the German/Austrian DPV-registry were included. The cross-sectional study comprised 45,722 subjects with T1D (n DFS =2,966) and 313,264 with T2D (n DFS =30,904). In DFS, minor/major amputations were analyzed. To compare HbA 1C , neuropathy, nephropathy, cardiovascular disease risk factors, and macrovascular complications between patients with our without DFS, regression models were conducted. Confounders: age, sex, diabetes duration. In patients with DFS, a minor amputation was documented in 27.2% (T1D) and 25.9% (T2D), a major amputation in 10.2% (T1D) and 11.3% (T2D). Regression models revealed that neuropathy was more frequent in subjects with DFS compared to patients without DFS (T1D: 70.7 vs. 29.8%; T2D: 59.4% vs. 36.9%; both p<0.0001). Hypertension, nephropathy, peripheral vascular disease, stroke, or myocardial infarction were more common compared to patients without DFS (all p<0.0001). In T1D with DFS, a slightly higher HbA 1C (8.11% vs. 7.95%; p<0.0001) and in T2D with DFS a lower HbA 1C (7.49% vs. 7.69%, p<0.0001) was observed. One third of the patients with DFS had an amputation of the lower extremity. Especially neuropathy or peripheral vascular disease were more prevalent in patients with DFS. New concepts to prevent DFS-induced amputations and to reduce cardiovascular risk factors before the occurrence of DFS are necessary. This article is protected by copyright. All rights reserved.

    Intracranial arterial stenosis (ICAS) is a common cause of ischemic stroke in Asians. Decreased muscle mass is one of the major causes of chronic disease in adults. The purpose of this study was to analyze the relationship between muscle mass and ICAS in Korean adults. For this study, we selected a total of 10,530 participants (mean age, 43.3 years; 8558 men) in a health screening program, for whom transcranial Doppler (TCD) ultrasound was used to detect >50% ICAS based on criteria modified from the stroke outcomes and neuroimaging of intracranial atherosclerosis trial. Body composition was evaluated by bioelectrical impedance analysis (BIA). Skeletal muscle index (SMI) was calculated with muscle mass/weight (kg) * 100. Among the total patient population, 322 (3.1%) subjects had ICAS. Subjects with ICAS were older, and had higher mean values for fasting glucose, body mass index and blood pressure compared with those without ICAS. Subjects with ICAS had significantly lower muscle mass, SMI and higher percent body fat compared with those without ICAS. In logistic regression analysis, the subjects in the highest tertile of muscle mass had the lowest odds ratio for ICAS with the lowest tertile group of muscle mass as the reference group even after adjusting for age, systolic blood pressure, fasting blood glucose, sex, smoking and exercise (OR 0.650, 95% CI 0.442-0.955). Subjects with ICAS had significantly decreased muscle mass compared with those without ICAS in Korean adults. The risk for ICAS was lower in subjects with higher muscle mass.

    Objectives: The purpose of this study was to compare mean liver T 1ρ values in patients with liver cirrhosis and healthy control subjects in order to evaluate T 1ρ as a potential MR biomarker for liver cirrhosis. Materials and methods: Ten healthy control subjects (mean age 42.7 years; 6 female, 4 male) and 21 patients with clinically diagnosed liver cirrhosis (mean age 56.5 years; 5 female, 16 male) were examined at 1.5 T (Magnetom Avanto, Siemens). T 1ρ -weighted images were acquired using a 2D TurboFLASH sequence (TR/TE 3/1.31 ms, FA 8°, FoV 309 × 380 mm, resolution 2 × 2 × 6 mm, acquisition time 15 s, slice thickness 6 mm) with spin-lock preparation. T 1ρ maps were calculated from five breath-hold measurements, performed with different spin-lock times (4, 8, 16, 32 and 48 ms). Mean liver T 1ρ values of healthy control subjects and patients with liver cirrhosis were calculated and compared using Student t-test. In addition, a receiver operating characteristic (ROC) curve analysis was performed to evaluate the utility of mean liver T 1ρ values for the prediction of liver cirrhosis. Results: Mean liver T 1ρ values in patients with liver cirrhosis (57.4 ± 7.4 ms) were significantly higher than those of healthy subjects (47.8 ± 4.2 ms; p = 0.0007). According to the ROC analysis at a threshold value of 50.1 ms the sensitivity and specificity of mean liver T 1ρ in predicting liver cirrhosis were 90.5% and 90%, respectively. The area under the ROC curve was 0.90. Conclusion: Mean liver T 1ρ values in patients with liver cirrhosis were significantly higher than those in healthy subjects suggesting a potential role of liver T 1ρ as a MR biomarker for liver cirrhosis

    Full Text Available The objectives of this study were to evaluate and compare the use of linear and nonlinear methods for analysis of heart rate variability (HRV in healthy subjects and in patients after acute myocardial infarction (AMI. Heart rate (HR was recorded for 15 min in the supine position in 10 patients with AMI taking β-blockers (aged 57 ± 9 years and in 11 healthy subjects (aged 53 ± 4 years. HRV was analyzed in the time domain (RMSSD and RMSM, the frequency domain using low- and high-frequency bands in normalized units (nu; LFnu and HFnu and the LF/HF ratio and approximate entropy (ApEn were determined. There was a correlation (P < 0.05 of RMSSD, RMSM, LFnu, HFnu, and the LF/HF ratio index with the ApEn of the AMI group on the 2nd (r = 0.87, 0.65, 0.72, 0.72, and 0.64 and 7th day (r = 0.88, 0.70, 0.69, 0.69, and 0.87 and of the healthy group (r = 0.63, 0.71, 0.63, 0.63, and 0.74, respectively. The median HRV indexes of the AMI group on the 2nd and 7th day differed from the healthy group (P < 0.05: RMSSD = 10.37, 19.95, 24.81; RMSM = 23.47, 31.96, 43.79; LFnu = 0.79, 0.79, 0.62; HFnu = 0.20, 0.20, 0.37; LF/HF ratio = 3.87, 3.94, 1.65; ApEn = 1.01, 1.24, 1.31, respectively. There was agreement between the methods, suggesting that these have the same power to evaluate autonomic modulation of HR in both AMI patients and healthy subjects. AMI contributed to a reduction in cardiac signal irregularity, higher sympathetic modulation and lower vagal modulation.

    Sleep-wake disturbances and concomitant cognitive dysfunction in Parkinson's disease (PD) contribute significantly to morbidity in patients and their carers. Subjectively reported daytime sleep disturbance is observed in over half of all patients with PD and has been linked to executive cognitive dysfunction. The current study used daytime actigraphy, a novel objective measure of napping and related this to neuropsychological performance in a sample of PD patients and healthy, age and gender-matched controls. Furthermore this study aimed to identify patients with PD who may benefit from pharmacologic and behavioural intervention to improve these symptoms. Eighty-five PD patients and 21 healthy, age-matched controls completed 14 days of wrist actigraphy within two weeks of neuropsychological testing. Objective napping measures were derived from actigraphy using a standardised protocol and subjective daytime sleepiness was recorded by the previously validated Epworth Sleepiness Scale. Patients with PD had a 225% increase in the mean nap time per day (minutes) as recorded by actigraphy compared to age matched controls (39.2 ± 35.2 vs. 11.5 ± 11.0 minutes respectively, p napping duration between patients, as recorded by actigraphy were not distinguished by their ratings on the subjective measurement of excessive daytime sleepiness. Finally, those patients with excessive daytime napping showed greater cognitive deficits in the domains of attention, semantic verbal fluency and processing speed. This study confirms increased levels of napping in PD, a finding that is concordant with subjective reports. However, subjective self-report measures of excessive daytime sleepiness do not robustly identify excessive napping in PD. Fronto-subcortical cognitive dysfunction was observed in those patients who napped excessively. Furthermore, this study suggests that daytime actigraphy, a non-invasive and inexpensive objective measure of daytime sleep, can identify patients with PD

    Full Text Available Aim: Sialic acid plays a central role in the functioning of biological systems, in stabilizing the glycoproteins and cellular membranes, assisting in cell–cell recognition and interaction. The aim of this study is to evaluate and compare the periodontal health status and salivary Sialic acid levels in patients suffering from chronic obstructive pulmonary diseases (COPD and chronic periodontitis patients. Materials and Methods: Ninety subjects were included in the study, which were divided into the following groups, 30 in each group. Group 1: patients suffering from COPD and chronic periodontitis, Group 2: periodontitis patients without any systemic diseases Group 3: healthy subjects. Unstimulated whole saliva samples were collected around 9–10 AM; 2 h after the subjects had breakfast. The sialic acid content was determined by a combined modification of the thiobarbituric acid method of Skoza and Mohos. Results: The mean salivary sialic acid levels were least in the healthy group followed by the periodontitis group, and it was highest in the COPD group. Conclusions: We can thus conclude that promotion of dental care knowledge is very much essential in the prevention and treatment of COPD. Thus, estimation of levels of salivary sialic acid can be used as an adjunct to diagnose the current periodontal disease status and to assess the treatment outcomes in subjects with COPD and chronic periodontitis.

In the mark of an agreement among the HQGCBA and the Authority Regulatory Nuclear (ARN), it is in execution a study protocol for the one boarding diagnoses and therapeutic of radioinduced cutaneous leisure. They exist individual variations that can condition the response to the ionizing radiations (IR), so much in accidental exposures as having programmed (radiotherapy, radiology interventionist). In this context, the individual radiosensitivity is evaluated in the patients signed up in this protocol that presented sharp or late cutaneous reactions, with grades of severity 3-4 (approaches EORTC/RTOG). The capacity of repair of the DNA was evaluated in outlying blood lymphocytes irradiated in vitro (2 Gy, gamma of Co-60) by means of the micronucleus techniques and comet essay in alkaline conditions. In this work two cases in those that is applied this study protocol, the therapeutic answer and its correlate with the discoveries of the radiosensitivity tests is presented. Case 1: patient of feminine sex, subjected to external radiotherapy by a breast infiltrating ductal carcinoma; developed sharp cutaneous radiotoxicity grade 3 (confluent humid epithelitis) that motivate the interruption of the treatment. Case 2: patient of masculine sex, subjected to a coronary angioplasty (interventionist radiology); developed late cutaneous radiotoxicity grade 4 (ulceration in dorsal region). Both patients were treated with topical trolamine associated to systemic administration of pentoxiphiline and antioxidants. The therapeutic answer is evaluated by means of clinical pursuit, photographic serial register and complementary exams (thermography and ultrasonography of high frequency). In the case 1 the answer was very favorable, with precocious local improvement and complete remission of symptoms and

    Mental health is increasingly defined not only by the absence of illness but by the presence of subjective well-being (SWB). Previous cohort studies have consistently shown that indicators of SWB predict favorable life outcomes, including better mental and somatic health, and longevity....... The favorable effects associated with SWB have prompted new research aimed at raising happiness and wellbeing through individual interventions and public health initiatives. Standard observational studies of individual-level associations, however, are subject to potential confounding of exposure and outcome...

    Solutions for Wellness (SfW) is an educational 3-month program concerning nutrition and exercise for persons with psychiatric disorders on psychotropic medication, who have weight problems. This observational study assessed the impact of SfW on subjective well-being, weight and waist circumference (WC). Data was collected at 49 psychiatric clinics. Where the SfW program was offered patients could enter the intervention group; where not, the control group. Subjective well-being was measured by the Subjective Well-being under Neuroleptics scale (SWN), at baseline, at the end of SfW participation, and at a follow-up 6 months after baseline. Demographic, disease and treatment data was also collected. 314 patients enrolled in the SfW group, 59 in the control group. 54% of the patients had schizophrenia, 67% received atypical antipsychotics, 56% were female. They averaged 41 +/- 12.06 years and had a BMI of 31.4 +/- 6.35. There were significant differences at baseline between groups for weight, SWN total score and other factors. Stepwise logistic models controlling for baseline covariates yielded an adjusted non-significant association between SfW program participation and response in subjective well-being (SWN increase). However, statistically significant associations were found between program participation and weight-response (weight loss or gain weight and WC but not with improved subjective well-being as measured with the SWN scale.

    Single-Subject Design is used in several areas such as education and biomedicine. However, no suited formal vocabulary exists for annotating the detailed configuration and the results of this type of research studies with the appropriate granularity for looking for information about them. Therefore, the search for those study designs relies heavily on a syntactical search on the abstract, keywords or full text of the publications about the study, which entails some limitations. To present SSDOnt, a specific purpose ontology for describing and annotating single-subject design studies, so that complex questions can be asked about them afterwards. The ontology was developed following the NeOn methodology. Once the requirements of the ontology were defined, a formal model was described in a Description Logic and later implemented in the ontology language OWL 2 DL. We show how the ontology provides a reference model with a suitable terminology for the annotation and searching of single-subject design studies and their main components, such as the phases, the intervention types, the outcomes and the results. Some mappings with terms of related ontologies have been established. We show as proof-of-concept that classes in the ontology can be easily extended to annotate more precise information about specific interventions and outcomes such as those related to autism. Moreover, we provide examples of some types of queries that can be posed to the ontology. SSDOnt has achieved the purpose of covering the descriptions of the domain of single-subject research studies. Schattauer GmbH.

    The phenomenon of sleep benefit (SB) in Parkinson's disease (PD), whereby waking motor function is improved despite no dopaminergic treatment overnight, is controversial. Previous studies suggested a significant discrepancy between subjective functional and objective motor improvement. The aim of this study was to determine how well subjective reporting of SB correlates with objective measures and if true motor improvement can be predicted by a standardized questionnaire. Ninety-two patients with PD participated. A structured questionnaire was developed to assess subjective SB. Quantitative motor assessment was performed using a validated smartphone application. Objective motor SB was considered to be present when the waking motor function was similar or superior to the daytime on-state. Twenty (22%) patients showed objective motor improvement on waking compared to end-of-dose. Most patients (77%) reported subjective SB without corresponding objective motor benefit. Our structured questionnaire could not predict Motor SB. The ability to delay morning medications and a perception of indifference or paradoxical worsening following the morning levodopa dose may suggest Motor SB. Most patients experience subjective SB with no measureable motor improvement. This perceived benefit could be related to non-motor improvement that is distinctly different to objective motor benefit.

    Brain hemisphere lesions often cause a contralesional tilt of the subjective vertical (SV) a phenomenon related to spatial neglect and postural disorders. Depending on the method employed, different perceptual systems come into play when this gravitational vertical is assessed. Here, we compared the anatomical and psychophysical characteristics of modality-dependent SV biases in patients with right hemisphere stroke. The SV was measured with visual, haptic and visual-haptic modalities (SV, SVV, SVHV) in 46 patients with a relatively recent stroke. Voxel-based lesion-symptom mapping (performed with NPM(®)) was used to highlight brain areas in which lesions best explained the severity of task biases (p rights reserved.

    To study human figure drawing in a group of Alzheimer's disease (AD) patients and compare it with a group of patients with mild cognitive impairment (MCI) and controls. We evaluated consecutive outpatients over a one-year period. Patients were classified as affected by AD or by MCI. All patients and controls underwent a simplified version of the human-figure drawing test and MMSE. A qualitative and quantitative analysis of all human figures was obtained. 112 AD, 100 MCI patients and 104 controls were enrolled. AD patients drew human figures poor in details and globally smaller than MCI patients and controls. Human figures drawn by MCI patients are intermediate in body height between those of the AD patients and the healthy subjects. The head-to-body ratio of human figures drawn by AD patients is greater than controls and MCI patients, while the human figure size-relative-to-page space index is significantly smaller. Body height is an independent predictor of cognitive impairment correlating with its severity and with the number of the figure's details. Human figures drawn by AD patients are different from those drawn by healthy subjects and MCI patients. Human figure drawing test is a useful tool for orienting cognitive impairment's diagnosis.

    The response of right ventricular ejection fraction (RVEF) during exercise and its relationship to the location and extent of coronary artery disease are not fully understood. We have recently developed and validated a new method for scintigraphic evaluation of RVEF using rapid multiple-gated equilibrium scintigraphy and multiple right ventricular regions of interest. The technique has been applied during upright bicycle exercise in 10 normal subjects and 20 patients with coronary artery disease. Resting RVEF was not significantly different between the groups (0.49 +- 0.04 vs 0.47 +- 0.09, respectively, mean +- SD). In all 10 normal subjects RVEF rose (0.49 +- 0.04 to 0.66 +- 0.08, p < 0.01) at peak exercise. At peak exercise in coronary artery disease patients, the group RVEF remained unchanged (0.47 +- 0.09 to 0.50 +- 0.11, p = NS), but the individual responses varied. In the coronary artery disease patients, the relationship between RVEF response to exercise and exercise left ventricular function, septal motion and right coronary artery stenosis were studied. Significant statistical association was found only between exercise RVEF and right coronary artery stenosis. RVEF rose during exercise in seven of seven patients without right coronary artery stenosis (0.42 +- 0.06 to 0.58 +- 0.08, p = 0.001) and was unchanged or fell in 12 of 13 patients with right coronary artery stenosis (0.50 +- 0.09 to 0.45 +- 0.10, p = NS). We conclude that (1) in normal subjects RVEF increases during upright exercise and (2) although RVEF at rest is not necessarily affected by coronary artery disease, failure of RVEF to increase during exercise, in the absence of chronic obstructive pulmonary disease or valvular heart disease, may be related to the presence of significant right coronary artery stenosis

    This study aimed to investigate the correlation of psychiatric disorders with tinnitus and tinnitus handicap scores. A total of 30 patients and 30 otherwise healthy people were enrolled for the study. Somatoform disorder questionnaire SDQ-20 was filled in by both the study and the control group. Tinnitus handicap scores were filled in study group. Tinnitus handicap scores were 28.1 ± 19.8, and somatoform disorder questionnaire scores were 30.5 ± 7.3 in the tinnitus group. In the control group the somatoform disorder questionnaire scores were 25.4 ± 4.6. (1) We found a statistically significant difference between somatoform disorder questionnaire scores between groups (p tinnitus handicap scores and somatoform disorder questionnaire scores in study group (p = 0.0). The correlation between these tests was positively strong (R = 0.782). (3) There was no statistical difference between genders. We recommend investigating patients with long-lasting tinnitus for psychiatric comorbidity in relation to somatoform disorders in cooperation with psychiatric clinics.

    Several omics technologies are underway worldwide with an aim to unravel the pathophysiology of a complex phenotype such as type 2 diabetes mellitus (T2DM). While recent studies imply a clinically relevant and potential biomarker role of circulatory miRNAs in the etiology of T2DM, there is lack of data on this aspect in Indians—an ethnic population characterized to represent ‘Asian Indian phenotype’ known to be more prone to develop T2DM and cardiovascular disease than Europeans. We performed global serum miRNA profiling and the validation of candidate miRNAs by qRT-PCR in a cohort of subjects comprised of normal glucose tolerance (NGT), impaired glucose tolerance (IGT) and patients with T2DM. Our study revealed 4 differentially expressed miRNAs (miR-128, miR-130b-3p, miR-374a-5p, miR-423-5p) in subjects with IGT and T2DM patients compared to control subjects. They were positively or negatively correlated to cholesterol levels, HbA1C, HOMA-IR and fasting insulin. Interestingly, circulating level of miR-128 and miR-130b-3p were also altered in serum of diet-induced diabetic mice compared to control animals. Among the altered circulating miRNAs, miR-128 had never been described in previous studies/populations and appeared to be a ‘New Lead’ in Indians. It was positively correlated with cholesterol both in prediabetic subjects and in diet-induced diabetic mice, suggesting that its increased level might be associated with the development of dyslipedemia associated with T2DM. Our findings imply directionality towards biomarker potential of miRNAs in the prevention/diagnosis/treatment outcomes of diabetes. PMID:26020947

    This study aimed to determine the impact of cochlear implantation on speech understanding in noise, subjective perception of hearing, and tinnitus perception of adult patients with unilateral severe to profound hearing loss and to investigate whether duration of deafness and age at implantation would influence the outcomes. In addition, this article describes the auditory training protocol used for unilaterally deaf patients. This is a prospective study of subjects undergoing cochlear implantation for unilateral deafness with or without associated tinnitus. Speech perception in noise was tested using the Bamford-Kowal-Bench speech-in-noise test presented at 65 dB SPL. The Speech, Spatial, and Qualities of Hearing Scale and the Abbreviated Profile of Hearing Aid Benefit were used to evaluate the subjective perception of hearing with a cochlear implant and quality of life. Tinnitus disturbance was measured using the Tinnitus Reaction Questionnaire. Data were collected before cochlear implantation and 3, 6, 12, and 24 months after implantation. Twenty-eight postlingual unilaterally deaf adults with or without tinnitus were implanted. There was a significant improvement in speech perception in noise across time in all spatial configurations. There was an overall significant improvement on the subjective perception of hearing and quality of life. Tinnitus disturbance reduced significantly across time. Age at implantation and duration of deafness did not influence the outcomes significantly. Cochlear implantation provided significant improvement in speech understanding in challenging situations, subjective perception of hearing performance, and quality of life. Cochlear implantation also resulted in reduced tinnitus disturbance. Age at implantation and duration of deafness did not seem to influence the outcomes.

    The effects of somatostatin (growth hormone release inhibiting hormone) on basal gastrin were studied in patients suffering from pernicious anaemia and chronic renal and liver disease, and during sequential arginine/insulin-stimulated gastrin release in normal subjects. When basal gastrin concentrations were normal (10-50 pg/ml) in controls and in patients who were in renal and liver failure, somatostatin had no effect on gastrin levels. Raised basal gastrin levels in pernicious anaemia and in 2 cases of chronic renal disease, were significantly inhibited by somatostatin with a half-life (T-half) of 3 to 4 minutes. Arginine infusion caused an insignificant rise in serum gastrin which was unaffected by somatostatin, whereas insulin hypoglycaemia significantly stimulated gastrin release, which was inhibited by somatostatin.

    Full Text Available Background: Studies on neurocognitive impairment among patients presenting with multi-infarct dementia (MID have received little attention from non-Western societies, and the Arab world is no exception. To our knowledge, this is the first study to characterize neurocognitive, affective and vegetative functioning in patients with MID in Oman. Methods: In this study, we recruited 20 Omani patients presenting with MID and age- and gender-matched controls at the outpatient clinic of the Department of Behavioral Medicine, Sultan Qaboos University Hospital, Sultan Qaboos University, Muscat, Oman. In addition to the collection of clinical and demographic information, various cognitive batteries were administered to the consenting participants, including those indexing nonverbal reasoning abilities, working memory (attention, concentration and recall and executive functioning. Questionnaires that elicit the affective range and the quality of sleep were also administered. Results: Compared with the matched healthy subjects, the patients diagnosed with MID significantly differed in the presently operationalized indices of visuospatial function, semantic memory and affective and vegetative functioning. In contrast, episodic memory and some attentional capacities were not significantly different compared with the control subjects. Conclusions: The present study was explorative and clinically designed to describe neurocognitive functioning in patients with MID seeking consultation at a tertiary care center in Oman. Our data are necessary for planning and setting up community services and health care programs for demented patients in a society where dementia is a growing silent epidemic. © 2014 S.

    The aim of this study was to prospectively investigate whether the structure of cerebral small-resistance arteries is related to cerebral perfusion parameters as measured with dynamic susceptibility-weighted contrast magnetic resonance imaging (DSC-MRI) in a selected cohort of hypertensive and normotensive patients. Ten hypertensive and 10 normotensive patients were included in the study. All patients underwent neurosurgical intervention for an intracranial tumor and were investigated with DSC-MRI at 1.5 T. Cerebral small-resistance arteries were dissected from a small portion of morphologically normal cerebral tissue and mounted on an isometric myograph for the measurement of the media-to-lumen (M/L) ratio. A quantitative assessment of cerebral blood flow (CBF) and volume (CBV) was performed with a region-of-interest approach. Correlation coefficients were calculated for normally distributed variables. The institutional review board approved the study, and informed consent was obtained from all patients. Compared with normotensive subjects, hypertensive patients had significantly lower regional CBF (mL/100 g/min) in the cortical grey matter (55.63 ± 1.90 vs 58.37 ± 2.19, p < 0.05), basal ganglia (53.34 ± 4.39 vs 58.22. ± 4.33, p < 0.05), thalami (50.65 ± 3.23 vs 57.56 ± 4.45, p < 0.01), subcortical white matter (19.32 ± 2.54 vs 22.24 ± 1.9, p < 0.05), greater M/L ratio (0.099 ± 0.013 vs 0.085 ± 0.012, p < 0.05), and lower microvessel density (1.66 ± 0.67 vs 2.52 ± 1.28, p < 0.05). A statistically significant negative correlation was observed between M/L ratio of cerebral arteries and CBF in the cortical grey matter (r = -0.516, p < 0.05), basal ganglia (r = -0.521, p < 0.05), thalami (r = -0.527 p < 0.05), and subcortical white matter (r = -0.612, p < 0.01). Our results indicate that microvascular structure might play a role in controlling CBF, with possible clinical consequences. (orig.)

    The primary objective of this study was to investigate the pharmacokinetic profile of gadoterate meglumine in pediatric patients younger than 2 years; the secondary objectives were to document its efficacy and safety. This was a Phase IV open-label, prospective study conducted in 9 centers (4 countries). Forty-five patients younger than 2 years with normal estimated glomerular filtration rate and scheduled to undergo routine gadolinium-enhanced magnetic resonance imaging (MRI) of any organ were included and received a single intravenous injection of gadoterate meglumine (0.1 mmol/kg). To perform the population pharmacokinetics analysis, 3 blood samples per subject were drawn during 3 time windows at time points allocated by randomization. Gadoterate meglumine concentrations were best fitted using a 2-compartmental model with linear elimination from central compartment. The median total clearance adjusted to body weight was estimated at 0.06 L/h per kg and increased with estimated glomerular filtration rate according to a power model. The median volume of distribution at steady state (Vss) adjusted to body weight was estimated at 0.047 L/kg. Estimated median terminal half-life (t1/2β) was 1.35 h, and the median systemic exposure (area under the curve) was 1591 μmol h/L. Efficacy was assessed by comparing precontrast +postcontrast images to precontrast images in a subset of 28 subjects who underwent an MRI examination of brain, spine, and associated tissues. A total of 28 lesions were identified and analyzed in 15 subjects with precontrast images versus 30 lesions in 16 subjects with precontrast + postcontrast images. Lesion visualization was improved with a mean (SD) increase in scores at subject level of 0.7 (1.0) for lesion border delineation, 0.9 (1.6) for internal morphology, and 3.1 (3.2) for contrast enhancement. Twenty-six adverse events occurred postinjection in 13 subjects (28.9%), including 3 serious reported in 1 subject (2.2%). One subject (2

    Research has been carried out in the town area of Milan on 275 subjects. For each patient the following data have been measured: ventilatory profile, aspecific bronchial reactivity, arterial concentration in CO and acid-base balance. The results obtained have been divided into four groups, according to the level of SO/sub 2/ in the area of residence of the subjects, who have also been studied with reference to the habit of smoking. The data obtained have shown (1) an alteration of the ventilatory function, with decrease of oxygen tension in arterial blood in all subjects. (2) Increase of bronchial irritability and CO concentration in arterial blood have been found in these subjects. (3) The division of the results according to the level of SO/sub 2/ pollution in the areas of residence of the patients showed the presence, in the most polluted areas of Milan (NE and SW), of higher levels of bronchial irritability and higher CO rates in arterial blood. (4) Cigarette smoking does not seem to play a major role in causing bronchial irritability. It certainly increases CO concentration: smokers have HbCO concentration higher than nonsmokers in all four areas. (5) Air pollution is more important than cigarette smoking in determining CO saturation of blood. Nonsmokers living in the most polluted areas of Milan (NE) show a higher concentration of CO in arterial blood than smokers living in the less polluted areas (SW).

    The authors studied the action of clebopride on gastric emptying in subjects with non-ulcer dyspepsia by using radioactive isotopes. Eighteen subjects complaining of dyspeptic symptoms were studied in whom the tests undertaken had not shown organic lesions of the digestive tract. Tests with radioactive isotopes were performed before and after administration of clebopride (0.5 mg, three times daily for 15 days). In all patients gastric emptying time was normalized and gastric peristalsis became regular. In addition, in 85% of the patients, symptoms disappeared or were markedly reduced. Side effects requiring withdrawal of the drug were not observed. The above study, therefore, showed clebopride to be a useful drug for the treatment of non-ulcer dyspepsia, thus confirming data found in the literature.

    Gastroesophageal reflux disease (GERD) is a well-recognized cause of impaired sleep in patients with frequent GERD symptoms, as well as those with sleep apnea. GERD's role in sleep disturbance of minimally symptomatic patients with poor sleep quality is less clear. We aimed to define the prevalence of GERD-related sleep disturbance in minimally-symptomatic subjects with demonstrated insomnia, and to assess the changes in sleep efficiency in these subjects after vigorous acid suppression. We recruited subjects aged 18-75 years reporting at least 6 months of insomnia, and sleep difficulty at least three nights per week. Subjects with a BMI > 30, a history of snoring or ongoing use of proton pump inhibitor or H2 receptor antagonist were excluded. Subjects underwent concurrent sleep study with dual channel 24-h pH study. Sleep efficiency, defined as the percentage of time after sleep initiation that the subject actually slept, and spontaneous arousal index, defined as the number of arousals per hour, were calculated. Those with a sleep study demonstrating poor sleep quality (sleep efficiency of 10 arousals/h for those aged 15 for those who were 45 or older) and no obstructive sleep apnea were treated with rabeprazole 20 mg PO BID x 14 days. After 14 days, the subjects underwent repeat sleep study with pH monitoring. The GERD Symptom Assessment Scale (GSAS), the Epworth Sleepiness Scale (ESS) and the Functional Outcomes of Sleep Questionnaire (FOSQ) were administered to subjects at study inception and after 2 weeks of therapy. Twenty-four subjects reporting insomnia were enrolled, and 20 met criteria for disordered sleep and no OSA. Seventeen completed both the first and second studies, and 16 were adequate for analysis. Baseline GSAS demonstrated trivial or no reflux symptoms in the cohort (no subject scored > 8 out of 45 on GSAS, corresponding to a median rating of reflux symptoms of "not at all"). Four of 16 subjects (25%) demonstrated abnormal pH studies at baseline

    To verify whether the subjectively and objectively assessed patient's skills in applying compression therapy constitute a predicting factor of venous ulcer recurrence. Systematic implementation of compression therapy by the patient is a core of prophylaxis for recurrent ulcers. Therefore, patient education constitutes a significant element of care. However, controversies remain if all individuals benefit equally from education. A retrospective analysis. The study included medical records of patients with venous ulcers (n = 351) treated between 2001 and 2011 at the Clinic for Chronic Wounds at Bydgoszcz Clinical Hospital. We compared two groups of patients, (1) with at least one episode of recurrent ulcer during the five-year observation period, and (2) without recurrences throughout the analysed period in terms of their theoretical skills and knowledge on compression therapy recorded at baseline and after one month. Very good self-assessment of a patient's compression therapy skills and weak assessment of these skills by a nurse proved significant risk factors for recurrence of the ulcers on univariate analysis. The significance of these variables as independent risk factors for recurrent ulcers has been also confirmed on multivariate analysis, which also took into account other clinical parameters. Building up proper compression therapy skills among the patients should be the key element of a properly construed nurse-based prophylactic program, as it is the most significant modifiable risk factor for recurrent ulcers. Although the development of compression skills is undeniably important, also other factors should be considered, e.g. surgical correction of superficial reflux. Instruction on compression therapy should be conducted by properly trained nursing personnel - the nurses should have received both content and psychological training. The compression therapy training should contain practical instruction with guided exercises and in-depth objective

    The quantification of interdependencies within autonomic nervous system has gained increasing importance to characterise healthy and psychiatric disordered subjects. The present work introduces a biosignal processing approach, suggesting a computational resource to estimate coherent or synchronised interactions as an eventual supportive aid in the diagnosis of primary insomnia and schizophrenia pathologies. By deploying linear, nonlinear and statistical methods upon 25 electroencephalographic and electrocardiographic overnight sleep recordings, the assessment of cross-correlation, wavelet coherence and [Formula: see text]:[Formula: see text] phase synchronisation is focused on tracking discerning features amongst the clinical cohorts. Our results indicate that certain neuronal oscillations interact with cardiac power bands in distinctive ways responding to standardised sleep stages and patient groups, which promotes the hypothesis of subtle functional dynamics between neuronal assembles and (para)sympathetic activity subject to pathophysiological conditions.

    Although the nipple and areola of the breast constitute a unique and prominent area on the chest, so far no study has been done on the functional properties of their skin surfaces. To study the stratum corneum (SC) covering the areola using noninvasive methods. Eighteen adult healthy subjects comprising nine men and nine women and 18 age- and sex-matched patients with atopic dermatitis (AD), none of whom had visible skin lesions, participated in the study. Transepidermal water loss (TEWL), skin surface hydration and skin surface lipid levels were measured on the areola and adjacent breast skin. The size of the skin surface corneocytes of these skin regions was assessed. All the healthy subjects showed significantly higher TEWL accompanied by smaller sized corneocytes on the areola than on the adjacent breast skin. Only female subjects revealed a significantly higher skin surface hydration state together with significantly increased skin surface lipid levels on the areola than on the adjacent breast skin. These sex differences were observed even in patients with AD. Comparison between healthy individuals and the patients with AD demonstrated higher TEWL, decreased skin surface hydration state and lower skin surface lipid levels associated with smaller sized corneocytes in the areola in the patients with AD, especially in male patients. In adults, the SC barrier function and SC water-binding capacity of the areola were functionally poorer than in the adjacent skin, being covered by smaller sized corneocytes and lower amounts of skin surface lipids, especially in men and in patients with AD. © 2011 The Authors.

    Introduction Sleep-wake disturbances and concomitant cognitive dysfunction in Parkinson’s disease (PD) contribute significantly to morbidity in patients and their carers. Subjectively reported daytime sleep disturbance is observed in over half of all patients with PD and has been linked to executive cognitive dysfunction. The current study used daytime actigraphy, a novel objective measure of napping and related this to neuropsychological performance in a sample of PD patients and healthy, age and gender-matched controls. Furthermore this study aimed to identify patients with PD who may benefit from pharmacologic and behavioural intervention to improve these symptoms. Methods Eighty-five PD patients and 21 healthy, age-matched controls completed 14 days of wrist actigraphy within two weeks of neuropsychological testing. Objective napping measures were derived from actigraphy using a standardised protocol and subjective daytime sleepiness was recorded by the previously validated Epworth Sleepiness Scale. Results Patients with PD had a 225% increase in the mean nap time per day (minutes) as recorded by actigraphy compared to age matched controls (39.2 ± 35.2 vs. 11.5 ± 11.0 minutes respectively, p napping duration between patients, as recorded by actigraphy were not distinguished by their ratings on the subjective measurement of excessive daytime sleepiness. Finally, those patients with excessive daytime napping showed greater cognitive deficits in the domains of attention, semantic verbal fluency and processing speed. Conclusion This study confirms increased levels of napping in PD, a finding that is concordant with subjective reports. However, subjective self-report measures of excessive daytime sleepiness do not robustly identify excessive napping in PD. Fronto-subcortical cognitive dysfunction was observed in those patients who napped excessively. Furthermore, this study suggests that daytime actigraphy, a non-invasive and inexpensive objective measure of

    To assess the subjective success and quality of life of adult patients post endoscopic endonasal dacryocystorhinostomy (EE-DCR) for acquired nasolacrimal duct obstruction. Retrospective, questionnaire study performed at least 6 months post EE-DCR. Hundred and ten of the 282 consecutive patients who underwent EE-DCR. A standardised questionnaire (Glasgow Benefit Inventory, GBI) was used to analyse the quality of life. The questionnaire examines four parameters, providing total, subscale, social, and physical scores. We aimed to assess patient experience following EE-DCR surgery. Total GBI scores range from -100 to +100, the former reflecting maximal negative benefit and corresponding to subjective worsening of tearing and impact on quality of life. Any positive score reflects a satisfactory surgical outcome and +100 represents maximal positive benefit. A score of zero is no perceived benefit. The average age was 62 years, 63% were female. In three of the parameters measured, there was a subjective improvement post surgery: subscale score 22.16 (95% CI: 15.23-29.09), total score 15.04 (95% CI: 9.74-20.35), and social support score 4.67 (95% CI: 0.93-8.42). Physical health scored -4.47 (95% CI: -10.25 to 1.32). Secondary analyses demonstrate no statistical significance with respect to outcome whether a trainee or consultant performed the procedure. Younger patients (under split median of 63.5) had a better total score 19.04 (95% CI: 11.35-27.74) than those older than 63.5 years (11.04, 95% CI: 3.61-18.47). This study shows that EE-DCR gave patients improvement in quality of life, proven by a validated questionnaire. The mean total score of 15.04 found in our study compares with the 18.7 recorded by Feretis et al in 2009. Results were irrespective of the grade of surgeon, similar to the findings of Fayers et al for functional successes. This study supports the use of EE-DCR for the improvement of quality of life in adult patients.

    The aim of this study was to determine the subjective evaluation of a breast cancer peer support program based on a survey of the participants who completed the program. Semistructured interviews were held with 10 women with breast cancer. The responses were subject to a qualitative inductive analysis. Women with breast cancer who participated in the breast cancer peer support program evaluated the features of the program and cited benefits, such as "Receiving individual peer support tailored to your needs," "Easily consulted trained peer supporters," and "Excellent coordination." Also indicated were benefits of the peer support that was received, such as "Receiving peer-specific emotional support," "Obtaining specific experimental information," "Re-examining yourself," and "Making preparations to move forward." The women also spoke of disadvantages, such as "Strict management of personal information" and "Matching limitations." In this study, the subjective evaluation of a peer support program by women with breast cancer was clarified . The women with breast cancer felt that the program had many benefits and some disadvantages. These results suggest that there is potential for peer support-based patient-support programs in medical services that are complementary to the current support that is provided by professionals. © 2016 Japan Academy of Nursing Science.

    The world-wide occurrence of agglutinating antibodies to four coccoid anaerobes belonging to Eubacterium, Peptostreptococcus and Coprococcus spp. was investigated in 937 coded sera from patients suffering from Crohn's disease, ulcerative colitis, various other diseases and from healthy controls. Positive results were found in 59% of patients with Crohn's disease, 29% of patients with ulcerative colitis, and 8% of both diseased and healthy control subjects. Patients with Crohn's disease of the colon had more positive tests (67%) than patients with disease confined to the small bowel (46%). The results show that agglutinating antibodies to the coccoid anaerobes occur more frequently in patients with Crohn's disease than in other subjects in widely varying geographic regions.

Subjective well-being was measured by the Subjective Well-being under Neuroleptics scale (SWN, at baseline, at the end of SfW participation, and at a follow-up 6 months after baseline. Demographic, disease and treatment data was also collected. Results 314 patients enrolled in the SfW group, 59 in the control group. 54% of the patients had schizophrenia, 67% received atypical antipsychotics, 56% were female. They averaged 41 ± 12.06 years and had a BMI of 31.4 ± 6.35. There were significant differences at baseline between groups for weight, SWN total score and other factors. Stepwise logistic models controlling for baseline covariates yielded an adjusted non-significant association between SfW program participation and response in subjective well-being (SWN increase. However, statistically significant associations were found between program participation and weight-response (weight loss or gain Conclusions SfW program participation was associated with maintaining or decreasing weight and WC but not with improved subjective well-being as measured with the SWN scale.

    Full Text Available Sustainability education (SE is included in school curricula to integrate the principles, values, and practices of sustainable development (SD into all education. This study investigates lower secondary school subject teachers as educators for sustainability. A survey was used to study the perceptions of 442 subject teachers from 49 schools in Finland. There were significant differences between the subject teachers’ perceptions of their SE competence, and the frequency with which they used different dimensions of SE (ecological, economic, social, well-being, cultural in their teaching varied. Teachers’ age had a small effect, but gender, school, and its residential location were nonsignificant factors. Teachers could be roughly classified into three different subgroups according to their perceptions of the role of SE in their teaching; those who considered three SE dimensions rather often and used holistic sustainability approaches in their teaching (biology, geography, history; those who considered two or three dimensions often but were not active in holistic teaching (mother tongue, religion, visual arts, crafts, music, physical and health education, and home economics and those who used one SE dimension or consider only one holistic approach in their teaching (mathematics, physics, chemistry and language. Subject teachers’ awareness of their SE competence is important to encourage them to plan and implement discipline-based and interdisciplinary SE in their teaching. The specific SE expertise of subject teachers should be taken into account in teacher training and education.

    The aim of this study was to determine the functional activity of cranio-mandibular system in patients with TMG osteoarthrosis. The study included 20 patients with TMG osteoarthrosis and 20 healthy subjects representing control group. The EMG examination was performed according to standard protocol developed in Milan University. The symmetry index values in the group with TMG osteoarthrosis were lower than in the control group (78.76±12.29%), while Torque values were higher (8.53±14.62%). EMG standardized indexes allowed differentiating TMG osteoarthrosis.

    Full text: In this work the doses to critical organs in pediatric patient subjected to studies of multi cutting skull tomography were determined. The study included patient smaller than 16. The used tomograph was a Siemens Somaton 16 plus multi cutting. The dosimetry one carries out with thermoluminescent dosemeters of LiF:Mg,Cu,P +Ptfe of national production. This dosemeters type was used due to it characteristics, such as low fading, equivalence with the tissue, easy handling and reading and independence of it answer with the radiation energy. The value of the absorbed doses in organs in the simple study results half of the obtained value in the contrasted study that which indicates that the CTDI{sub vol} is proportional to the dose to organ. In the case of the skull three-dimensional reconstruction tomography the CTDI{sub vol} was practically the same one that for simple tomography was practically; however, the doses to organs differed significantly. When comparing the TDI{sub vol} value of the three-dimensional reconstruction tomography with that of the contrasted tomography the obtained reason it was 1:2; however, the doses to organ didn't show the same relationship and the absorbed dose in the case of the thyroid gland was even bigger in the study of three-dimensional reconstruction. The value of the CTDI{sub vol} is a good indicator of the exposure factors selected for the tomographic exploration and it is useful for the determination of the effective dose, but it doesn't indicate the absorbed dose to organ.

    An RIA for Ep has been developed that is highly sensitive and specific. A homogeneous Ep preparation was labeled with 125 I by the chloramine-T method to a specific activity of 90 to 136 micro Ci/microgram and immunoreactivity of 80%. Ep antiserum, which was produced to a human urinary Ep preparation (80 U/mg of protein), was adsorbed with normal human urinary and serum proteins without any loss in sensitivity of the RIA to increase the specificity of the assay. A good correlation was seen between the RIA and the exhypoxic polycythemic mouse assay (corr. coef. 0.967; slope 1.05 and y intercept 0.75). Ep titers in sera from 175 hematologically normal human subjects exhibited a normal frequency distribution and ranged between 5.8 and 36.6 mU/ml with a mean of 14.9 +/- 4.7 (S.D.) and median of 14.3 Serum Ep titers were markedly elevated in seven patients with aplastic anemia and one patient with pure red cell aplasia (1350 to 20,640 mU/ml) and were lower than normal in two patients with polycythemia vera (8.1 and 9.4 mU/ml). The serum Ep titers in a prenephrectomy patient with chronic glomerulonephritis (32.1 mU/ml) decreased to below normal levels (9.04 mU/ml) after nephrectomy. The cord serum erythropoietin titers in 10 IDM [90.82 +/- 134.1 (S.D.) mu/ml] returned to values within the normal range (13.86 +/- 5.55) on day 3 after birth, suggesting the utility of the RIA in elucidating the role of hypoxia and/or insulin in increased erythropoiesis in IDM. The serum Ep titers in patients with anemias and polycythemias were compared to those of normal human subjects and agreed well with pathophysiologic mechanisms of these hemopoietic disorders, confirming the validity of the RIA

    The ratio of hematocrit (Hct) to hemoglobin (Hb) in the people with normal red blood cell (RBC) morphology is generally three to one. We studied Hct/Hb ratios among patients with alpha-thalassemias (Hb H, H-CS, AEBart, AEBart-CS, EFBart and EFBart-CS diseases) diagnosed by high performance liquid chromatography, and compared them with normal subjects and with patients having anemia due to chronic kidney disease (CKD). The Hct and Hb levels were derived by automated analyzer. The means +/- SD of the Hct/Hb ratios were 3.5 +/- 0.2 (range 3.3 - 4.1), 3.0 +/- 0.1 (range 2.9 - 3.2) and 3.0 +/- 0.1 (range 2.8 - 3.2) in the alpha-thalassemia, normal and CKD groups, respectively. The mean Hct/Hb ratio in subjects with alpha-thalassemia was higher than the mean in normal subjects and in those with CKD. The Hct/Hb ratios for each genotype of the alpha-thalassemia were not different from each other. The underlying mechanisms for the higher Hct/Hb ratio among those with alpha-thalassemia are theorized to be less density and/or more hydration of a-thalassemia RBCs, more entrapment of plasma in the spun RBC, the high percent of nucleated RBC and WBC interference. A ratio of 3.5 +/- 0.2 may be helpful in cases of moderate anemia when typing only shows Hb A and E, to consider investigation for alpha-thalassemia, or in cases of alpha-thalassemia with acute blood loss, if the Hct is less than 35%, in the decision to transfuse.

    Several variables have been identified as risk factors for conversion to overt psychosis in ultra-high risk for psychosis (UHR) individuals. Although almost two-thirds of them do not experience a transition to psychosis, they still exhibit functional disabilities. Other subjective developmental features may be useful for a more precise identification of individuals at UHR. Avoidant behaviors are consistently reported in schizophrenia and in UHR individuals and may be the reflection of a pattern of personality. Thus, personality features in UHR individuals deserves further research. The objective of the present study was to compare temperament and character dimensions between UHR individuals, patients with schizophrenia and healthy controls. One hundred participants (25 UHR individuals, 25 schizophrenia patients and 50 control subjects) where evaluated with the Temperament and Character Inventory-Revised (TCI-R). Univariate ANOVAs followed by Bonferroni tests were used. UHR individuals and schizophrenia patients exhibited higher levels of Harm Avoidance (HA) when compared to control subjects. For HA1 Anticipatory worry vs Uninhibited optimism and HA4 Fatigability & asthenia, UHR and schizophrenia groups showed similar scores and both groups were higher compared to control subjects. With respect to Cooperativeness (CO), UHR and schizophrenia reported lower scores than control subjects, in particular CO2 Empathy vs Social disinterest and CO3 Helpfulness vs unhelpfulness. This study replicates and extends the consideration of HA as a psychopathological related endophenotype and gives us further information of the possible role of personality features in the expression of some of the social dysfunctions observed both in prodromal subjects and schizophrenia patients.

    Perception of low subjective social status (SSS) relative to others in society or in the community has been associated with increased risk of cardiovascular disease. Our objectives were to determine whether low SSS in society was associated with barriers to access to care or hospital readmission in patients with established cardiovascular disease, and whether perceptions of discordantly high SSS in the community modified this association. We conducted a prospective cohort study from 2009 to 2013 in Canada, United States, and Switzerland in patients admitted to hospital with acute coronary syndrome (ACS). Data on access to care and SSS variables were obtained at baseline. Readmission data were obtained 12 months post-discharge. We conducted multivariable logistic regression to model the odds of access to care and readmission outcomes in those with low versus high societal SSS. One thousand ninety patients admitted with ACS provided both societal and community SSS rankings. The low societal SSS cohort had greater odds of reporting that their health was affected by lack of health care access (OR 1.48, 95% CI 1.11, 1.97) and of experiencing cardiac readmissions (1.88, 95% CI 1.15, 3.06). Within the low societal SSS cohort, there was a trend toward fewer access to care barriers for those with discordantly high community SSS though findings varied based on the outcome variable. There were no statistically significant differences in readmissions based on community SSS rankings. Low societal SSS is associated with increased barriers to access to care and cardiac readmissions. Though attenuated, these trends remained even when adjusting for clinical and sociodemographic factors, suggesting that perceived low societal SSS has health effects above and beyond objective socioeconomic factors. Furthermore, high community SSS may potentially mitigate the risk of experiencing barriers to access to health care in those with low societal SSS, though these associations were not

    Full Text Available INTRODUCTION: Sleep-wake disturbances and concomitant cognitive dysfunction in Parkinson's disease (PD contribute significantly to morbidity in patients and their carers. Subjectively reported daytime sleep disturbance is observed in over half of all patients with PD and has been linked to executive cognitive dysfunction. The current study used daytime actigraphy, a novel objective measure of napping and related this to neuropsychological performance in a sample of PD patients and healthy, age and gender-matched controls. Furthermore this study aimed to identify patients with PD who may benefit from pharmacologic and behavioural intervention to improve these symptoms. METHODS: Eighty-five PD patients and 21 healthy, age-matched controls completed 14 days of wrist actigraphy within two weeks of neuropsychological testing. Objective napping measures were derived from actigraphy using a standardised protocol and subjective daytime sleepiness was recorded by the previously validated Epworth Sleepiness Scale. RESULTS: Patients with PD had a 225% increase in the mean nap time per day (minutes as recorded by actigraphy compared to age matched controls (39.2 ± 35.2 vs. 11.5 ± 11.0 minutes respectively, p < 0.001. Significantly, differences in napping duration between patients, as recorded by actigraphy were not distinguished by their ratings on the subjective measurement of excessive daytime sleepiness. Finally, those patients with excessive daytime napping showed greater cognitive deficits in the domains of attention, semantic verbal fluency and processing speed. CONCLUSION: This study confirms increased levels of napping in PD, a finding that is concordant with subjective reports. However, subjective self-report measures of excessive daytime sleepiness do not robustly identify excessive napping in PD. Fronto-subcortical cognitive dysfunction was observed in those patients who napped excessively. Furthermore, this study suggests that daytime

    HPRL was iodinated a modification of the enzymatic method using lactoperoxidase. By solid-phase RIA using antibody-coated disposable plastic microtiter trays, it was confirmed that the second peak consisted of the immunoreactive material that was used for RIA. For the measurement of plasma hPRL levels, the double antibody technique was used to separate bound from free labeled hormones. Basal plasma hPRL levels in normal subjects were less than 20 ng/ml. The mean basal hPRL levels were 10.2 +- 4.9 (Mean+-SD) ng/ml in 13 normal men and 9.6+-5.4 ng/ml in 8 normal women; no statistically significant sex difference was observed. When synthetic TRH was administered intravenously to a normal male subject, the maximum increase in plasma hPRL above the baseline level increased linearly as a function of the log of the TRH dose between 25 and 100 μg of TRH. Intravenous administration of 500 μg of TRH caused a significant increase in plasma hPRL in all of the 10 normal subjects tested. Plasma hPRL levels in 2 patients with Sheehan's syndrome and in a patient with operated-irradiated chromophobe adenoma tended to be low, and they showed no significant increase in plasma hPRL after TRH injection. Basal plasma hPRL levels in most of the patients with hypothalamopituitary tumor tended to be high. Plasma hPRL levels were normal in most patients with pituitary dwarfism. Plasma hPRL levels in 2 patients with hyperthyroidism tended to be low, and they showed no significant hPRL response to TRH, while patients with hypothyroidism showed normal or rather exaggerated hPRL response to TRH. Plasma hPRL levels were normal in most of the patients with Cushing's syndrome and plasma hPRL responses to TRH in these patients were normal. TRH-induced hPRL secretion tended to be impaired in patients receiving long-term and high doses of glucocorticoid. (auth.)

    The aim of this study is to present an estimate of the effective dose received by newborn patients hospitalized in NICU and subjected to X-ray examinations of the chest in the AP projection. Initially, were followed examinations chest X-rays performed on newborn patients and subsequently, simulated in a newborn simulator object. The ESAK values obtained by TLDs were used to calculate the effective dose obtained at each examination by Caldose{sub X} software. The estimated values for the effective dose in the simulated exams in this study range from 2,3μSv the 10,7μSv. The results achieved are, generally, inferior to those reported for similar previous studies. (author)

    Plasma from black male patients with essential hypertension was bioassayed for vascular Na+-K+ pump inhibitory activity. Halves of the same rat tail artery were incubated for two hours in boiled plasma supernates from a hypertensive patient and a paired age-, sex-, and race-matched normotensive subject and then ouabain-sensitive 86 Rb uptake was measured. Ouabain-sensitive 86 Rb uptake by their leukocytes was also measured. Eighteen pairs of subjects were studied. The uptakes were not significantly different in the hypertensive patients and control subjects. However, when we selected from the eighteen hypertensive patients, nine with low plasma renin activity on the day of the study, uptakes were reduced in the hypertensive patients relative to the paired control subjects. We also assayed plasma supernates from normotensive black and white male subjects before and after acute volume expansion (2.5 L saline IV + 1.5 L distilled water orally over a three-hour period) and from paired normotensive subjects before and after sham volume expansion and obtained a positive bioassay in the expanded subjects both on intraindividual and interindividual comparisons. These studies demonstrate increased vascular Na+-K+ pump inhibitory activity in the plasma of black male patients with low renin essential hypertension and in the plasma of normotensive subjects after acute volume expansion. The findings suggest that the inhibitory activity in the hypertensive subjects' plasma is related to volume expansion, relative or absolute

    No study on injury of the inferior cerebellar peduncle (ICP) in patients with mild traumatic brain injury (mTBI) has been reported. This study, using diffusion tensor tractography (DTT), attempted to demonstrate injury of the ICP in patients with mTBI. Three patients with mTBI resulting from a car accident and 18 normal healthy control subjects were enrolled in this study. Diffusion tensor imaging data were acquired at 2 months (patient 1) and 3 months (patients 2 and 3) after onset and the ICP was reconstructed. The Balance Error Scoring System was used for evaluation of balance at the same time diffusion tensor imaging scanning was performed. The ICPs were discontinued at the upper portion of the vertical cerebellar branch and the transverse cerebellar branch (patient 1) and the proximal portion of the transverse cerebellar branch (patients 2 and 3) compared to the normal control subjects. Regarding DTT parameters, in the three patients, the fibre number of the ICPs was decreased by more than 2 SD compared with those of subjects in the control group. Evaluation of the ICP using DTT would be useful in patients with a balance problem after mTBI.

    To analyze possible relationships between gynecomastia and clinical and biochemical parameters in a large cohort of subjects with sexual dysfunction (SD). A consecutive series of 4,023 men attending our Outpatient Clinic for SD was retrospectively studied. After excluding Klinefelter's syndrome patients, the prevalence of gynecomastia was 3.1 %. Subjects with gynecomastia had significantly lower testosterone (T) levels; the association retained statistical significance after adjusting for age and life-style. However, only 33.3 % of subjects with gynecomastia were hypogonadal. Gynecomastia was associated with delayed puberty, history of testicular or hepatic diseases, as well as cannabis abuse. Patients with gynecomastia more frequently reported sexual complaints, such as severe erectile dysfunction [odds ratio (OR) = 2.19 (1.26-3.86), p = 0.006], lower sexual desire and intercourse frequency [OR = 1.23 (1.06-1.58) and OR = 1.84 (1.22-2.78), respectively; both p Gynecomastia was also positively associated with severe obesity, lower testis volume and LH, and negatively with prostate-specific antigen levels. The further adjustment for T did not affect these results, except for obesity. After introducing body mass index as a further covariate, all the associations retained statistical significance, except for delayed ejaculation and ANDROTEST score. When considering gynecomastia severity, we found a step-wise, T-independent, decrease and increase of testis volume and LH, respectively. Gynecomastia was also associated with the use of several drugs in almost 40 % of our patients. Gynecomastia is a rare condition in subjects with SD, and could indicate a testosterone deficiency that deserves further investigation.

    As a part of health survey in relation to air pollution, 16 smokers(11 from 'high' and 5 from 'low' zone) were studied with extensive serial lung functions, chest radiography and radioaerosol lung scanning. The clinical diagnosis were chronic bronchitis(COPD) in 9 subjects; but others (4 'High' and 3 'Low') were considered normal. The values of FVC, FEV were normal in most of these three groups, but FEV 1 /FVC percent values were lower in subjects from 'high' zone.The functional declines were higher in normals of 'high' zone. Radioaerosol (ventilation) scans (with technetium 99 ) showed a normal picture in 2 COPD and 3 normal subjects; in 3 COPD and 1 normal subjects the abnormalities were definite. For perfusion scans, 2 COPD and 3 normal subjects showed a normal pattern while definite abnormalities were seen in 1 COPD and 1 normal subjects. Lung scans may pick up abnormalities in normal smokers at an early stage. (author)

    In The Netherlands, pharmaceutical-grade cultivated cannabis is distributed for medicinal purposes as commissioned by the Ministry of Health. Few studies have thus far described its therapeutic efficacy or subjective (adverse) effects in patients. The aims of this study are to assess the therapeutic satisfaction within a group of patients using prescribed pharmaceutical-grade cannabis and to compare the subjective effects among the available strains with special focus on their delta-9-tetrahydrocannabinol and cannabidiol content. In a cross-sectional and natural design, users of pharmaceutical-grade cannabis were investigated with questionnaires. Medical background of the patients was asked as well as experienced therapeutic effects and characteristics of cannabis use. Subjective effects were measured with psychometric scales and used to compare among the strains of cannabis used across this group of patients. One hundred two patients were included; their average age was 53 years and 76% used it for more than a year preceding this study. Chronic pain (53%; n = 54) was the most common medical indication for using cannabis followed by multiple sclerosis (23%; n = 23), and 86% (n = 88) of patients (almost) always experienced therapeutic satisfaction when using pharmaceutical cannabis. Dejection, anxiety, and appetite stimulation were found to differ among the 3 strains of cannabis. These results show that patients report therapeutic satisfaction with pharmaceutical cannabis, mainly pain alleviation. Some subjective effects were found to differ among the available strains of cannabis, which is discussed in relation to their different tetrahydrocannabinol/cannabidiol content. These results may aid in further research and critical appraisal for medicinally prescribed cannabis products.

    Despite studies by several investigators of human gastrointestinal 65Zn absorption, implications of these data for evaluation of functional zinc status are unclear because limited numbers of normal subjects have been studied. To evaluated zinc absorption in normal humans, 75 subjects (31 women, 44 men, ages 18 to 84 yr) were given 10 micro Ci carrier-free 65Zn orally after an overnight fast. Absorption calculated from total body retention measured 7, 14, and 21 days after administration of tracer was 65 +/- 11% (mean +/- 1 SD), range from 40 to 86%. Comparison of these results with those for patients with a variety of diseases indicate that patients exhibit a wider range of absorption and, in four of six studies patients exhibit decreased mean zinc absorption. These results of gastrointestinal zinc absorption in a large number of normal humans offer a basis for a clearer comparison with data from patients who exhibit abnormalities of zinc absorption

    To perform a comparative quantitative and qualitative analysis of Chinese and non-Chinese medical ethics literature using systematic research and literature analysis in order to discern research trends in the area and provide baseline data as a reference for relevant decision making and further study. We retrieved articles using MeSH terms and keywords related to medical ethics in PubMed and CNKI, and then constructed a set of charts by applying word co-occurrence, The Pathfinder Networks algorithms, an included subject chart, a research field relationship chart, and strategy coordination charts. The total of number of papers retrieved from PubMed was six times that retrieved from CNKI. Outside China, medical ethics has been studied in eight fully shaped subject fields, including morals, ethical review, physician-patient relationships, clinical trials, euthanasia, ethics education, clinical ethics, and health policy. In contrast, medical ethics research in China is still confined to five subject fields: morals, physician-patient relations, medical ethics education, ethical review, and medical research. Medical ethics research outside China emphasizes the application of medical ethics to solve emerging problems in clinical and medical research. It is mainly centered on morals, ethical review, and physician-patient relations. By comparison, medical ethics research in China places greater emphasis on morals and medical education. In order to narrow this gap between China and other countries, we should broaden the research scope of medical ethics and add more applied research, such as ethical review and medical education. © 2012 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

    The sacroiliac (SI) joints of 45 asymptomatic subjects were prospectively studied to define better the normal appearance of SI joints on CT scans and therby attach appropriate significance to CT signs of sacroiliitis. Joint space narrowing, subchondral sclerosis, erosions, ankylosis, osteophytes, subchondral cysts, and symmetry were evaluted. The results indicate that the SI joints demonstrate symmetry in patients under the age of 30 (100% of subjects in this age group). Those CT findings of sacroiliitis that occurred infrequently in the asymptomatic population, and hence may represent good indicators of sacroiliac disease, include increased sacral subchondral sclerosis in subjects under the age of 40 (11%), bilateral or unilateral uniform joint space of less than 2 mm (2% or 0%, respectively), erosions (2%), and intraarticular ankylosis (0%)

    Quantitative thallium-201 myocardial exercise scintigraphy was tested in two patient populations representing alternative standards for cardiac normality: group I comprised 18 male uncatherized patients with a low likelihood of coronary artery disease (CAD); group II contained 41 patients with normal coronary arteriograms. Group I patients were younger, they achieved a higher rate-pressure product than group II patients; all had normal findings by phisical examination and electrocardiography at rest and exercise. Group II patients comprised 21 females, 11 patients showed abnormal electrocardiography at rest, and five patients showed ischemic ST depression during exercise. Twelve patients had sign of minimal CAD. Twelve patients revealed abnormal visual and quantitative thallium findings, three of these patients had minimal CAD. Profiles of uptake and washout of thallium-201 were derived from both patient groups, and compared with normal limits developed by Maddahi et al. Furthermore, low likelihood and angiographically normal patients may differ substantially, and both sets of normal patients should be considered when establishing criteria of abnormality in exercise thallium imaging. When commercial software containing normal limits for quantitative analysis of exercise thallium-201 imaging is used in clinical practice, it is mandatory to compare these with normal limits of uptake and washout of thallium-201, derived from the less heterogeneous group of low-likelihood subjects, which should be used in selecting a normal population to define normality.

    Subject motion in positron emission tomography (PET) studies leads to image blurring and artifacts; simultaneously acquired magnetic resonance imaging (MRI) data provides a means for motion correction (MC) in integrated PET/MRI scanners. To assess the effect of realistic head motion and MR-based MC on static [ 18 F]-fluorodeoxyglucose (FDG) PET images in dementia patients. Observational study. Thirty dementia subjects were recruited. 3T hybrid PET/MR scanner where EPI-based and T 1 -weighted sequences were acquired simultaneously with the PET data. Head motion parameters estimated from high temporal resolution MR volumes were used for PET MC. The MR-based MC method was compared to PET frame-based MC methods in which motion parameters were estimated by coregistering 5-minute frames before and after accounting for the attenuation-emission mismatch. The relative changes in standardized uptake value ratios (SUVRs) between the PET volumes processed with the various MC methods, without MC, and the PET volumes with simulated motion were compared in relevant brain regions. The absolute value of the regional SUVR relative change was assessed with pairwise paired t-tests testing at the P = 0.05 level, comparing the values obtained through different MR-based MC processing methods as well as across different motion groups. The intraregion voxelwise variability of regional SUVRs obtained through different MR-based MC processing methods was also assessed with pairwise paired t-tests testing at the P = 0.05 level. MC had a greater impact on PET data quantification in subjects with larger amplitude motion (higher than 18% in the medial orbitofrontal cortex) and greater changes were generally observed for the MR-based MC method compared to the frame-based methods. Furthermore, a mean relative change of ∼4% was observed after MC even at the group level, suggesting the importance of routinely applying this correction. The intraregion voxelwise variability of regional SUVRs

    The purpose of this study was to identify quantitatively measurable morphologic optical coherence tomography (OCT) characteristics in patients with an acute episode of central serous chorioretinopathy (CSC) and evaluate their correlation to functional and psychological variables for their use in daily clinical practice. Retinal thickness (RT), the height, area and volume of subretinal fluid (SRF)/pigment epithelium detachments were evaluated using the standardized procedures of the Vienna Reading Center. These morphologic characteristics were compared with functional variables [best-corrected visual acuity (BCVA), contrast sensitivity (CS), retinal sensitivity/microperimetry, fixation stability], and patients' subjective handicap from CSC using the National Eye Institute 25-item Visual Function Questionnaire (NEI VFQ-25). Data from 39 CSC patients were included in this analysis. Three different SRF height measures showed a high negative correlation (r = -0.7) to retinal sensitivity within the central 9°, which was also negatively correlated with SRF area and volume (r = -0.6). The CS score and fixation stability (fixation points within 2°) showed a moderate negative correlation (r = -0.4) with SRF height variables. Comparison of the subjective handicap with morphological characteristics in spectral-domain (SD)-OCT showed SRF height had the highest correlation (r = -0.4) with the subjective problems reported and overall NEI VFQ-25 score. In conclusion, SRF height measured in SD-OCT showed the best correlation with functional variables and patients' subjective handicap caused by the disease and therefore seems to be the best variable to look at in daily clinical routine. Even though area and volume also show a correlation, these cannot be so easily measured as height and are therefore not suggested for daily clinical routine. © 2018 Acta Ophthalmologica Scandinavica Foundation.

    Full Text Available Aim: Nose is a resonator organ in production of voice. The aim of this study was to evaluate the effects of nasal obstruction caused by nasal polyposis on voice quality subjectively. Methods: Thirty-six patients diagnosed with nasal polyposis were included in the study. The 30-item voice handicap index 30 was used in order to evaluate subjective status of voice. Nasal endoscopy and computed tomography imaging of the paranasal sinuses were performed for each patient. Lund-Kennedy endoscopy scores and Lund-MacKay computed tomography scores were evaluated. Control group composed of 20 healthy subjects. Results: The mean voice handicap score in the patient group was 43.16 (SD 15.53 and it was 2.15 (SD 1.92 in control group. There was a statistically significant difference between the groups (p=0.001. The mean Lund-Kennedy and Lund-Mackay scores were 8.58 (SD 2.5 and 17 (SD 5.52, respectively. It was found that increased severity of nasal polyposis was the cause for decreased satisfaction with voice quality. Conclusion: Nasal obstruction caused by nasal polyposis affects voice quality adversely and as the severity of nasal polyposis increases, satisfaction with voice quality decreases.

    Altogether, our findings show that cross-sectional variations in overall white brain matter are linked to the metabolism of Alzheimer-like cortical areas and to cognitive performance in older hypertensive patients with only subjective memory complaints. Additional relationships with central BP strengthen the hypothesis of a contributing pathogenic role of hypertension.

    This study aimed to investigate whether the fatigue induced by sustained motor task in the jaw elevator muscles differed between healthy subjects and patients with temporomandibular disorder (TMD). Fifteen patients with TMD and thirteen age- and sex-matched healthy controls performed a fatigue test consisting of sustained clenching contractions at 30% maximal voluntary clenching intensity until test failure (the criterion for terminating the fatigue test was when the biting force decreased by 10% or more from the target force consecutively for >3 s). The pre- and post-maximal bite forces (MBFs) were measured. Surface electromyographic signals were recorded from the superficial masseter muscles and anterior temporal muscles bilaterally, and the median frequency at the beginning, middle and end of the fatigue test was calculated. The duration of the fatigue test was also quantified. Both pre- and post-MBFs were lower in patients with TMD than in controls (P fatigue test in TMD patients was significantly shorter than that of the controls (P fatigued, but the electromyographic activation process during the fatigue test is similar between healthy subjects and patients with TMD. However, the mechanisms involved in this process remain unclear, and further research is warranted. © 2017 John Wiley & Sons Ltd.

    Previous studies have shown depression-like sleep abnormalities in borderline personality disorder (BPD). However, findings in BPD are not unequivocal for REM dysregulation, as well as for a decrement of slow wave sleep and sleep continuity disturbances. Earlier findings in sleep EEG abnormalities in BPD may have been confounded by concomitant depressive symptoms. Twenty unmedicated female BPD patients without current comorbid major depression and 20 sex- and age-matched control subjects entered the study. Conventional polysomnographic parameters and for the first time sleep EEG spectral power analysis was performed on two sleep laboratory nights. Subjective sleep parameters were collected by sleep questionnaires in order to assess the relationship between objective and subjective sleep measurements. BPD patients showed a tendency for shortened REM latency and significantly decreased NonREM sleep (stage 2). Spectral EEG analysis showed increased delta power in total NREM sleep as well as in REM sleep in BPD patients. Subjective ratings documented drastically impaired sleep quality in BPD patients for the two weeks before the study and during the two laboratory nights. Not-depressed BPD patients only showed tendencies for depression-like REM sleep abnormalities. Surprisingly, BPD patients displayed higher levels of delta power in the sleep EEG in NREM sleep than healthy control subjects. There was a marked discrepancy between objective and subjective sleep measurements, which indicates an altered perception of sleep in BPD. The underlying psychological and neurobiological mechanisms of these alterations are still unclear and need to be clarified in future studies including interventions on a pharmacological and cognitive-behavioral level.

    Full Text Available ABSTRACT: Introduction & Objective: A common auditory complaint of multiple sclerosis patients, is misunderstanding speech in the presence of background noise. Evidence from animal and human studies has suggested that the medial olivocochlear bundle may play an important role in hearing noise. The medial olivocochlear bundle function can be evaluated by the suppression effect of transient otoacoustic emission in response to contralateral acoustic stimulation. The present study was conducted to investigate the suppression effect of transient otoacoustic emission in multiple sclerosis patients. Materials & Methods: This analytical case-control study was conducted on 34 multiple sclerosis patients (24 female, 10 male, aged 20-50 years and 34 controls matched for age and gender in Faculty of Rehabilitation, Tehran University of Medical Sciences in 2006. All cases were selected in simple random manner. The suppression effect of transient otoacoustic emission was evaluated by comparing the transient otoacoustic emission levels with and without contralateral acoustic stimulation. Data were analyzed using SPSS software and independent T- test. Results:There was no significant difference in transient otoacoustic emission levels of two groups, but a significantly reduced suppression effect of transient otoacoustic emission was found in multiple sclerosis patients, in compare with the controls. Conclusion: Outer hair cells activity in multiple sclerosis patients was normal but these patients presented low activity of the medial olivocochlear bundle system which could affect their ability to hear in the presence of background noise.

    Full Text Available The occurrence of liver disease and raised liver enzymes is common in diabetic patients and the increasing level of enzymes indicates the severity of hepatic injury. Very few studies have addressed this issue in Bangladesh though Bangladeshi population is very much susceptible to diabetes. This study investigated a total of 1400 diabetic patients and 100 non diabetic individuals to compare the level of liver enzymes between diabetic and non-diabetic subjects. The comparisons were made among subjects who were referred to the department of Gastro-hepato-pancreatic diseases (GHPD of BIRDEM with the clinical diagnosis of chronic hepatitis and other gastro-intestinal disorders. The investigations included alanine aminotransferase (ALT, aspartate aminotransferase (AST, alkaline phosphatase (ALP and bilirubin levels. The subjects were categorized with and without hepatitis based on these investigations. The biochemical markers (ALT, AST, ALP, bilirubin did not differ significantly between non-diabetic male and female subjects. Neither the differences were significant between diabetic males and females though the diabetic patients had higher level of markers. In contrast, when compared between diabetic and non-diabetic subjects there were striking differences in either sex. Compared with the non-diabetic the diabetic subjects had significantly higher level of ALT (48.3 vs. 277.0, AST (42.0 vs. 213.0 and ALP (148 vs. 302 in males (p<0.005 for all. Similarly, these values were found significantly higher in diabetic females than their non-diabetic counterparts (p<0.01. For bilirubin, it was also found significant in males (p<0.001. The study revealed that the liver enzymes were found elevated in both diabetic and non-diabetic subjects who were referred with clinically diagnosed hepatitis. The enzymes were found markedly elevated among the diabetic than non diabetic patients, which indicate hepatic injury was more marked among the diabetic patients. Further

    The width of interhemispheric fissure, lateral ventricles and third ventricle were measured using cranial computed tomography (CT; linear method) in 45 elderly inpatients with chronic schizophrenia and in 28 age-matched control subjects. Twenty-three patients were men and 22 were women. In addition, Mini-Mental State Examination, Brief Psychiatric Rating Scale (BPRS) and a subclass of BPRS were undertaken in all patients. There is a significant enlargement of the maximum width of the interhemispheric fissure (in both male and female) and a significant enlargement of ventricular system (more severe in men than in women) in aged schizophrenics, as seen with CT, compared with normal controls. These findings are consistent with previous studies of non-aged schizophrenic patients. Based upon the relation between psychiatric symptoms and CT findings, the most striking is a significant negative correlation between the third ventricle enlargement and the positive and depressive symptoms in all patients. This result suggests that the advanced third ventricle enlargement may decrease these symptoms in aged schizophrenics. (author)

    We aimed to investigate mastication predominance in healthy dentate individuals and patients with unilateral posterior missing teeth using objective and subjective methods. The sample comprised 50 healthy dentate individuals (healthy dentate group) and 30 patients with unilateral posterior missing teeth (partially edentulous group). Subjects were asked to freely chew three kinds of test foods (peanuts, beef jerky and chewing gum). Electromyographic activity of the bilateral masseter muscles was recorded. The chewing side (right side or left side) was judged by the level of root mean square electromyographic amplitude. Mastication predominance was then objectively assessed using the mastication predominant score and the mastication predominant index. Self-awareness of mastication predominance was evaluated using a modified visual analogue scale. Mastication predominance scores of the healthy dentate and partially edentulous groups for each test food were analysed. There was a significant difference in the distribution of the mastication predominant index between the two groups (P mastication predominant score was weakly correlated with self-awareness of mastication predominance in the healthy dentate group, whereas strong correlation was observed in the partially edentulous group (P mastication predominance and were more aware of mastication predominance than healthy dentate individuals. Our findings suggest that an objective evaluation of mastication predominance is more precise than a subjective method. © 2016 John Wiley & Sons Ltd.

    Directory of Open Access Journals (Sweden)

    Maristela Mian Ferreira

    Full Text Available Abstract Introduction: Otolith function can be studied by testing the subjective visual vertical, because the tilt of the vertical line beyond the normal range is a sign of vestibular dysfunction. Benign paroxysmal positional vertigo is a disorder of one or more labyrinthine semicircular canals caused by fractions of otoliths derived from the utricular macula. Objective: To compare the subjective visual vertical with the bucket test before and immediately after the particle repositioning maneuver in patients with benign paroxysmal positional vertigo. Methods: We evaluated 20 patients. The estimated position where a fluorescent line within a bucket reached the vertical position was measured before and immediately after the particle repositioning maneuver. Data were tabulated and statistically analyzed. Results: Before repositioning maneuver, 9 patients (45.0% had absolute values of the subjective visual vertical above the reference standard and 2 (10.0% after the maneuver; the mean of the absolute values of the vertical deviation was significantly lower after the intervention (p < 0.001. Conclusion: There is a reduction of the deviations of the subjective visual vertical, evaluated by the bucket test, immediately after the particle repositioning maneuver in patients with benign paroxysmal positional vertigo.

    Full Text Available The study aimed at establishing the prevalence index of facial asymmetry by extraoral clinical examination of orthodontic patients. The group of study included 384 subjects, selected from the patients who required a specialized orthodontic treatment. Facial asymmetry was evaluated by the parallelism of the horizontal planes and deviation of the menton and nasal pyramid. The age, sex and ecological environment from which one came, the type of dentition and of dento-maxillary anomaly were registered for each patient in part. In the experimental group, facial asymmetry was present in 4.7% of patients, menton deviation in 5.7%, and nasal pyramid deviation - in 3.4%. Significant associations were established between facial asymmetry and the type of dento-maxillary anomaly, classes of age and type of dentition. The results obtained indicate that the prevalence of facial asymmetries in orthodontic patients is especially important for the clinician, as the deviations should be established prior to the initiation of any orthodontic – possibly surgical - treatment.

    Automated measurements of the retinal nerve fiber layer thickness on circular OCT B-Scans provide physicians additional parameters for glaucoma diagnosis. We propose a novel retinal nerve fiber layer segmentation algorithm for frequency domain data that can be applied on scans from both normal healthy subjects, as well as glaucoma patients, using the same set of parameters. In addition, the algorithm remains almost unaffected by image quality. The main part of the segmentation process is based on the minimization of an energy function consisting of gradient and local smoothing terms. A quantitative evaluation comparing the automated segmentation results to manually corrected segmentations from three reviewers is performed. A total of 72 scans from glaucoma patients and 132 scans from normal subjects, all from different persons, composed the database for the evaluation of the segmentation algorithm. A mean absolute error per A-Scan of 2.9 µm was achieved on glaucomatous eyes, and 3.6 µm on healthy eyes. The mean absolute segmentation error over all A-Scans lies below 10 µm on 95.1% of the images. Thus our approach provides a reliable tool for extracting diagnostic relevant parameters from OCT B-Scans for glaucoma diagnosis.

    Despite adequate glycemic and blood pressure control, treated type 2 diabetic hypertensive subjects have a significantly elevated overall/cardiovascular risk. We studied 244 816 normotensive and 99 720 hypertensive subjects (including 7480 type 2 diabetics) attending medical checkups between 1992 and 2011. We sought to identify significant differences in overall/cardiovascular risk between hypertension with and without diabetes mellitus. Mean follow-up was 12.7 years; 14 050 all-cause deaths were reported. From normotensive to hypertensive populations, a significant progression in overall/cardiovascular mortality was observed. Mortality was significantly greater among diabetic than nondiabetic hypertensive subjects (all-cause mortality, 14.05% versus 7.43%; and cardiovascular mortality, 1.28% versus 0.7%). No interaction was observed between hemodynamic measurements and overall/cardiovascular risk, suggesting that blood pressure factors, even during drug therapy, could not explain the differences in mortality rates between diabetic and nondiabetic hypertensive patients. Using cross-sectional regression models, a significant association was observed between higher education levels, lower levels of anxiety and depression, and reduced overall mortality in diabetic hypertensive subjects, while impaired renal function, a history of stroke and myocardial infarction, and increased alcohol and tobacco consumption were significantly associated with increased mortality. Blood pressure and glycemic control alone cannot reverse overall/cardiovascular risk in diabetics with hypertension. Together with cardiovascular measures, overall prevention should include recommendations to reduce alcohol and tobacco consumption and improve stress, education levels, and physical activity. © 2017 American Heart Association, Inc.

    Full Text Available Abstract This is a report on a 37-patient continuation study of the open ended, Omega-3 Fatty Acid (O-3FA add-on study. Subjects consisted of the original 19 patients, along with 18 new patients recruited and followed in the same fashion as the first nineteen. Subjects carried a DSM-IV-TR diagnosis of Bipolar Disorder and were visiting a Mood Disorder Clinic regularly through the length of the study. At each visit, patients' clinical status was monitored using the Clinical Monitoring Form. Subjects reported on the frequency and severity of irritability experienced during the preceding ten days; frequency was measured by way of percentage of days in which subjects experienced irritability, while severity of that irritability was rated on a Likert scale of 1 – 4 (if present. The irritability component of Young Mania Rating Scale (YMRS was also recorded quarterly on 13 of the 39 patients consistently. Patients had persistent irritability despite their ongoing pharmacologic and psychotherapy. Omega-3 Fatty Acid intake helped with the irritability component of patients suffering from bipolar disorder with a significant presenting sign of irritability. Low dose (1 to 2 grams per day, add-on O-3FA may also help with the irritability component of different clinical conditions, such as schizophrenia, borderline personality disorder and other psychiatric conditions with a common presenting sign of irritability.

    Patients' trust in their physicians has recently become a focus of concern, largely owing to the rise of managed care, yet the subject remains largely unstudied. We undertook a qualitative research study of patients' self-reported experiences with trust in a physician to gain further understanding of the components of trust in the context of the patient-physician relationship. Twenty-nine patients participants, aged 26 to 72, were recruited from three diverse practice sites. Four focus groups, each lasting 1.5 to 2 hours, were conducted to explore patients' experiences with trust. Focus groups were audio-recorded, transcribed, and coded by four readers, using principles of grounded theory. The resulting consensus codes were grouped into seven categories of physician behavior, two of which related primarily to technical competence (thoroughness in evaluation and providing appropriate and effective treatment) and five of which were interpersonal (understanding patient's individual experience, expressing caring, communicating clearly and completely, building partnership/sharing power and honesty/respect for patient). Two additional categories were predisposing factors and structural/staffing factors. Each major category had multiple subcategories. Specific examples from each major category are provided. These nine categories of physician behavior encompassed the trust experiences related by the 29 patients. These categories and the specific examples provided by patients provide insights into the process of trust formation and suggest ways in which physicians could be more effective in building and maintaining trust.
