    Awake craniotomies (AC) could reduce neurological deficits compared with patients under general anesthesia, however, intraoperative seizure is a major reason causing awake surgery failure. The purpose of the study was to give a comprehensive overview the published articles focused on seizure incidence in awake craniotomy. Bibliographic searches of the EMBASE, MEDLINE,were performed to identify articles and conference abstracts that investigated the intraoperative seizure frequency of patients underwent AC. Twenty-five studies were included in this meta-analysis. Among the 25 included studies, one was randomized controlled trials and 5 of them were comparable studies. The pooled data suggested the general intraoperative seizure(IOS) rate for patients with AC was 8%(fixed effect model), sub-group analysis identified IOS rate for glioma patients was 8% and low grade patients was 10%. The pooled data showed early seizure rates of AC patients was 11% and late seizure rates was 35%. This systematic review and meta-analysis shows that awake craniotomy is a safe technique with relatively low intraoperative seizure occurrence. However, few RCTs were available, and the acquisition of further evidence through high-quality RCTs is highly recommended.

  4. Posterior Reversible Encephalopathy Syndrome in Patients who Underwent Cardiovascular Surgery

    The etiology of posterior reversible encephalopathy syndrome (pres) is not well understood. This entity has been reported in relation to multiple clinical conditions. It has been proposed that the vertebrobasilar circulation is more sensitive to injuries sustained by the central nervous system. Consequently, the main radiologic manifestations of this condition occur in the pareto-occipital regions. As its name implies, pres has a reversible nature. Once the noxious factors are withdrawn, both the vasogenic edema in affected areas, as well as neurological symptoms tends to resolve, whereas if the situation persists the lesions may progress to parenchymal ischemia. Cerebral computed tomography (CT) in pres may show hypodense areas in the affected white matter. Magnetic resonance (MR) imaging is used to better characterize the abnormal regions. This modality is capable of displaying an increased signal intensity in these areas on T2-weighted FLAIR sequences that is less apparent on diffusion-weighted images. In order to confirm this diagnosis, a follow up imaging study either with CT or MR can be performed approximately four weeks after the onset of symptoms. Nevertheless, an exact consensus with respect to the follow-up period has not been reached. The supporting findings for this diagnosis include resolution of the affected white matter and clinical remission without neurological sequelae. We hereby report three proven cases of pres in patients of different age groups that had undergone major cardiovascular surgery with extracorporeal circulation, a common factor that was thought to have been the precursor to this condition in these individuals.

    A 70-year-old man with distal bile duct carcinoma underwent a subtotal stomach-preserving pancreaticoduodenectomy without adjuvant chemotherapy. One and a half years after the surgery, elevated levels of serum SPan-1(38.1 U/mL)were observed and CT scans demonstrated a solitary metastasis, 25mm in size, in segment 8 of the liver. The patient received 2 courses of gemcitabine-cisplatin combination chemotherapy. No new lesions were detected after chemotherapy and the patient underwent a partial liver resection of segment 8. The pathological examination revealed a metachronous distant metastasis originating from the bile duct carcinoma. Subsequently, the patient received S-1 adjuvant chemotherapy for 6 months. Following completion of all therapies, the patient survived without tumor recurrence for 3 years and 10 months after the initial operation. Thus, surgical interventions might be effective in improving prognosis among selected patients with postoperative liver metastasis of bile duct carcinoma.

    The aim of this study was to analyze and compare the vocal quality in patients who underwent either submucosal turbinectomy or radiofrequency cauterization. In this study, we enrolled 60 patients diagnosed with inferior concha hypertrophy. These patients were divided into two groups by using computer program "Research Randomizer." Of the 60 patients, 30 underwent submucosal inferior turbinoplasty and 30 underwent radiofrequency cauterization. The control group was composed of 30 healthy adults with no nasal or upper aerodigestive system pathology. The patients were checked at weeks 1, 2, and 4. Voice records were taken before the procedure and at week 4 postprocedure. The mean age of patients in the inferior turbinoplasty group was 29.4 years (range: 19-42 years); in the radiofrequency group, it was 30.30 years (range: 18-50 years). There was no statistical difference in age between groups. In the inferior turbinoplasty group, there were 16 male and 14 female patients, and in the radiofrequency group, there were 13 male and 17 female patients. There was no significant difference in the number of males and females between groups. Voice professionals, especially singers, actors, and actresses, should be informed about possible voice changes before undergoing endonasal surgery because these individuals are more sensitive to changes in resonance organs. We believe that voice quality should be regarded as a highly important parameter when measuring the success of endonasal surgery. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc.

    Full Text Available BACKGROUND: Atherosclerosis is the main cause of peripheral artery occlusive disease (PAOD of the lower limbs. Patients with PAOD often also have obstructive atherosclerosis in other arterial sites, mainly the coronary arteries. This means that patients who undergo infrainguinal bypass to treat critical ischemia have a higher risk of AMI. There are, however, few reports in the literature that have assessed this risk properly. OBJECTIVE: The aim of this study was to determine the incidence of acute myocardial infarction in patients who underwent infrainguinal bypass to treat critical ischemia of the lower limbs caused by PAOD. MATERIAL AND METHODS: A total of 64 patients who underwent 82 infrainguinal bypass operations, from February 2011 to July 2012 were studied. All patients had electrocardiograms and troponin I blood assays during the postoperative period (within 72 hours. RESULTS: There were abnormal ECG findings and elevated blood troponin I levels suggestive of AMI in five (6% of the 82 operations performed. All five had conventional surgery. The incidence of AMI as a proportion of the 52 conventional surgery cases was 9.6%. Two patients died. CONCLUSION: There was a 6% AMI incidence among patients who underwent infrainguinal bypass due to PAOD. Considering only cases operated using conventional surgery, the incidence of AMI was 9.6%.

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks.Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass.Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014.Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively.Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    Full Text Available Abstract Objective: The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods: A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results: The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump as compared to Group 2 (off-pump. But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893, P>0.05 for bilateral pleural effusion (P=0.780]. Left pleural effusion was encountered to be lower in Group 2 (off-pump. The difference was found to be statistically significant (P<0.05, P=0.006. Conclusion: Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    We analyzed the incidence of bradycardia and the safety of patients with severely calcified coronary lesions who underwent orbital atherectomy without the insertion of a temporary pacemaker. The presence of severely calcified coronary lesions can increase the complexity of percutaneous coronary intervention due to the difficulty in advancing and optimally expanding the stent. High-pressure inflations to predilate calcified lesions may cause angiographic complications like perforation and dissection. Suboptimal stent expansion is associated with stent thrombosis and restenosis. Orbital atherectomy safely and effectively modifies calcified plaque to facilitate optimal stent expansion. The incidence of bradycardia in orbital atherectomy is unknown. Fifty consecutive patients underwent orbital atherectomy from February 2014 to September 2016 at our institution, none of whom underwent insertion of a temporary pacemaker. The final analysis included 47 patients in this retrospective study as 3 patients were excluded because of permanent pacemaker implantation. The primary endpoint was significant bradycardia, defined as bradycardia requiring emergent pacemaker placement or a heart rate pacemaker appears to be safe.

    Full Text Available BACKGROUND: Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and/or anatomical anomalies.

    A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy. We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia. Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer.

    Aim: To evaluate the incidence and associated factors of postoperative intense pain and haemodynamic changes during radiofrequency ablation of hepatocellular carcinoma. Materials and methods: A total of 123 consecutive hepatocellular carcinoma patients who underwent radiofrequency ablation were prospectively recruited. Patient factors, tumour characteristics, procedural factors, intraoperative haemodynamic changes, complications, postoperative events, laboratory values before and after ablation, and postoperative pain were evaluated. Postoperative pain was scored using a visual analogue scale after the procedure. Results: The mean age of the patients was 65.6 ± 9.6 years. In multiple logistic regression analysis, patients who underwent general anaesthesia [odds ratio (95% CI): 2.68 (1.23–5.81); p = 0.013] and had more postoperative nausea and vomiting episodes [3.10 (1.11–8.63); p = 0.036] were associated with intense pain. These findings remain robust after propensity score matching. For mean difference values between before and after RFA, higher in change in aspartate transaminase (p = 0.026), alanine transaminase (p = 0.016) and white blood cell count (p = 0.015), and lower in change in haemoglobin (p = 0.009) were also correlated with intense pain. There was no significant difference in haemodynamic changes between the general anaesthesia and local anaesthesia group during ablation. Conclusion: General anaesthesia, postoperative nausea and vomiting, and laboratory factors were associated with postoperative intense pain in patients who underwent radiofrequency ablation. Counselling and modification of analgesics should be considered in patients with related factors for intense pain

    The 3 phase 3 CHAMPION (Cangrelor vs Standard Therapy to Achieve Optimal Management of Platelet Inhibition) trials collectively demonstrated the safety of transitioning from cangrelor, a potent, parenteral rapidly-acting P2Y 12 inhibitor, to clopidogrel in patients who underwent percutaneous coronary intervention (PCI). However, variation in timing of therapy, site-specific binding, and drug half-lives may theoretically complicate switching to other oral P2Y 12 inhibitors. Since regulatory approval, limited data are available regarding the "real-world" safety and tolerability of transitioning to these more potent oral P2Y 12 antagonists. From November 2015 to January 2017, we evaluated the clinical profiles and efficacy and safety outcomes in cangrelor-treated patients who underwent PCI transitioned to clopidogrel (n = 42) or ticagrelor (n = 82) at a large, tertiary care center. Most patients receiving cangrelor underwent PCI with a drug-eluting stent for acute coronary syndrome via a radial approach in the background of unfractionated heparin. Stent thrombosis within 48 hours was rare and occurred in 1 patient treated with ticagrelor. Global Use of Strategies to Open Occluded Coronary Arteries-defined bleeding occurred in 20% of patients switched to ticagrelor and 29% of patients switched to clopidogrel, but none were severe or life-threatening. In conclusion, rates of stent thrombosis and severe/life-threatening bleeding were low and comparable with those identified in the CHAMPION program, despite use of more potent oral P2Y 12 inhibition.

    The postoperative results of laparoscopic distal pancreatectomy for solid pseudopapillary neoplasm of the pancreas (SPN), including the effects of spleen-preserving resection, are still to be elucidated. Of the 139 patients who underwent laparoscopic pancreatectomy for non-cancerous tumors, 14 consecutive patients (average age, 29.6 years; 1 man, 13 women) with solitary SPN who underwent laparoscopic distal pancreatectomy between March 2004 and June 2015 were enrolled. The tumors had a mean diameter of 4.8 cm. Laparoscopic spleen-preserving distal pancreatectomy was performed in eight patients (spleen-preserving group), including two cases involving pancreatic tail preservation, and laparoscopic spleno-distal pancreatectomy was performed in six patients (standard resection group). The median operating time was 317 min, and the median blood loss was 50 mL. Postoperatively, grade B pancreatic fistulas appeared in two patients (14.3%) but resolved with conservative treatment. No patients had postoperative complications, other than pancreatic fistulas, or required reoperation. The median postoperative hospital stay was 11 days, and the postoperative mortality was zero.None of the patients had positive surgical margins or lymph nodes with metastasis. The median follow-up period did not significantly differ between the two groups (20 vs 39 months, P = 0.1368). All of the patients are alive and free from recurrent tumors without major late-phase complications. Laparoscopic distal pancreatectomy might be a suitable treatment for patients with SPN. A spleen-preserving operation is preferable for younger patients with SPN, and this study demonstrated the non-inferiority of the procedure compared to spleno-distal pancreatectomy. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Full Text Available Objective: To observe the effect of different CO2 pneumoperitoneum pressure on the stress state in patients underwent gynecological laparoscopy. Methods: A total of 90 patients who were admitted in our hospital from February, 2015 to October, 2015 for gynecological laparoscopy were included in the study and divided into groups A, B, and C according to different CO2 pneumoperitoneum pressure. The changes of HR, BP, and PetCO2 during the operation process in the three groups were recorded. The changes of stress indicators before operation (T0, 30 min during operation (T1, and 12 h after operation (T2 were compared. Results: The difference of HR, BP, and PetCO2 levels before operation among the three groups was not statistically significant (P>0.05. HR, BP, and PetCO2 levels 30 min after pneumoperitoneum were significantly elevated when compared with before operation (P0.05. PetCO2 level 30 min after pneumoperitoneum in group B was significantly higher than that in group A (P0.05. Conclusions: Low pneumoperitoneum pressure has a small effect on the stress state in patients underwent gynecological laparoscopy, will not affect the surgical operation, and can obtain a preferable muscular relaxation and vision field; therefore, it can be selected in preference.

    Full Text Available Introduction: Emergency department thoracotomy (EDT may serve as the last survival chance for patients who arrive at hospital in extremis. It is considered as an effective tool for improvement of traumatic patients’ outcome. The present study was done with the goal of assessing the outcome of patients who underwent EDT and its predictive factors. Methods: In the present study, medical charts of 50 retrospective and 8 prospective cases underwent emergency department thoracotomy (EDT were reviewed during November 2011 to June 2013. Comparisons between survived and died patients were performed by Mann-Whitney U test and the predictive factors of EDT outcome were measured using multivariate logistic regression analysis. P < 0.05 considered statistically significant. Results: Fifty eight cases of EDT were enrolled (86.2% male. The mean age of patients was 43.27±19.85 years with the range of 18-85. The mean time duration of CPR was recorded as 37.12±12.49 minutes. Eleven cases (19% were alive to be transported to OR (defined as ED survived. The mean time of survival in ED survived patients was 223.5±450.8 hours. More than 24 hours survival rate (late survived was 6.9% (4 cases. Only one case (1.7% survived to discharge from hospital (mortality rate=98.3%. There were only a significant relation between ED survival and SBP, GCS, CPR duration, and chest trauma (p=0.04. The results demonstrated that initial SBP lower than 80 mmHg (OR=1.03, 95% CI: 1.001-1.05, p=0.04 and presence of chest trauma (OR=2.6, 95% CI: 1.75-3.16, p=0.02 were independent predictive factors of EDT mortality. Conclusion: The findings of the present study showed that the survival rate of trauma patients underwent EDT was 1.7%. In addition, it was defined that falling systolic blood pressure below 80 mmHg and blunt trauma of chest are independent factors that along with poor outcome.

    By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change

    Clinical experiences of adults who underwent surgery for esophageal atresia at birth is limited. There is some evidence that suggests considerable long-term morbidity, partly because of dysphagia, which has been reported in up to 85% of adult patients who undergo surgery for esophageal atresia. The authors hypothesized that dysphagia in this population is caused by dysmotility and⁄or anatomical anomalies. To determine the motor and anatomical causes of dysphagia. A total of 41 adults, followed at the Esophageal Atresia Clinic at Hôpital Saint-Luc (Montreal, Quebec), were approached to particpate in the present prospective study. Evaluation was completed using upper endoscopy, manometry and barium swallow for the participants who consented. The medical charts of respondents were systematically reviewed from the neonatal period to 18 years of age to assess medical and surgical history. All 41 patients followed at the clinic consented and were included in the study. Dysphagia was present in 73% of patients. Esophagogastroduodenoscopy was performed in 32 patients: hiatal hernia was present in 62% (n=20); esophageal diverticulum in 13% (n=4); macroscopic Barrett esophagus in 31% (n=10); and esophagitis in 19% (n=6). Histological esophagitis was present in 20% and intestinal metaplasia in 10%. There were no cases of dysplagia or adenocarcinoma. Esophageal manometry was performed on 56% of the patients (n=23). Manometry revealed hypomotility in 100% of patients and included an insufficient number of peristaltic waves in 96%, nonpropagating peristalsis in 78% and low-wave amplitude in 95%. Complete aperistalsis was present in 78%. The lower esophageal sphincter was abnormal in 12 (52%) patients, with incomplete relaxation the most common anomaly. Of the 41 patients, 29 (71%) consented to a barium swallow, which was abnormal in 13 (45%). The anomalies found were short esophageal dilation in 28%, delay in esophageal emptying in 14%, diverticula in 14% and stenosis in 7

    The study investigated the association between the location of transposed ovaries and posttreatment ovarian function in patients with early cervical cancer (IB1-IIA) who underwent radical hysterectomy and ovarian transposition with or without adjuvant therapies. Retrospective medical records were reviewed to enroll the patients with early cervical cancer who underwent ovarian transposition during radical hysterectomy at Samsung Medical Center between July 1995 and July 2012. Serum follicle-stimulating hormone (FSH) level was used as a surrogate marker for ovarian function. Twenty-one patients were enrolled. The median age and body mass index (BMI) were 31 years (range, 24-39 years) and 21.3 kg/m² (range, 17.7-31.2 kg/m²), respectively. The median serum FSH level after treatment was 7.9 mIU/mL (range, 2.4-143.4 mIU/mL). The median distance from the iliac crest to transposed ovaries on erect plain abdominal x-ray was 0.5 cm (range, -2.7 to 5.2 cm). In multivariate analysis, posttreatment serum FSH levels were significantly associated with the location of transposed ovaries (β = -8.1, P = 0.032), concurrent chemoradiation (CCRT) as an adjuvant therapy (β = 71.08, P = 0.006), and BMI before treatment (underweight: β = -59.93, P = 0.05; overweight: β = -40.62, P = 0.041). Location of transposed ovaries, adjuvant CCRT, and BMI before treatment may be associated with ovarian function after treatment. We suggest that ovaries should be transposed as highly as possible during radical hysterectomy to preserve ovarian function in young patients with early cervical cancer who might be a candidate for adjuvant CCRT and who have low BMI before treatment.

    BACKGROUND AND PURPOSE: Patient satisfaction is important in fast-track total hip and knee replacement (THR, TKR). We assessed: (1) how satisfied patients were with the treatment; (2) factors related to overall satisfaction; and (3) whether there was a difference between THR and TKR regarding...... length of stay (LOS) and patient satisfaction. PATIENTS AND METHODS: In this follow-up study, a consecutive series of 445 patients undergoing THR and TKR completed a questionnaire 2 weeks after discharge. LOS and short-term patient satisfaction with the fast-track management were measured. Patient...... satisfaction was measured using a numerical rating scale (NRS; 0-10). RESULTS: For THR, the median satisfaction score was 9-10 and for TKR it was 8.5-10 in all parameters. Older THR patients had higher overall satisfaction. No association was found between overall satisfaction following THR or TKR and sex...

    Full Text Available ABSTRACT OBJECTIVES: To evaluate through the visual analog scale (VAS the pain in patients undergoing total knee replacement (TKR with different pressures of the pneumatic tourniquet. METHODS: An observational, randomized, descriptive study on an analytical basis, with 60 patients who underwent TKR, divided into two groups, which were matched: a group where TKR was performed with tourniquet pressures of 350 mmHg (standard and the other with systolic blood pressure plus 100 mmHg (P + 100. These patients had their pain assessed by VAS at 48 h, and at the 5th and 15th days after procedure. Secondarily, the following were also measured: range of motion (ROM, complications, and blood drainage volume in each group; the data were subjected to statistical analysis. RESULTS: After data analysis, there was no statistical difference regarding the incidence of complications (p = 0.612, ROM (p = 0.202, bleeding after 24 and 48 h (p = 0.432 and p = 0.254 or in relation to VAS. No correlation was observed between time of ischemia compared to VAS and bleeding. CONCLUSIONS: The use of the pneumatic tourniquet pressure at 350 mmHg or systolic blood pressure plus 100 mmHg did not influence the pain, blood loss, ROM, and complications. Therefore the pressures at these levels are safe and do not change the surgery outcomes; the time of ischemia must be closely observed to avoid major complications.

    PTP1B is involved in the oncogenesis of breast cancer. In addition, neoadjuvant therapy has been widely used in breast cancer; thus, a measurement to assess survival improvement could be pathological complete response (pCR). Our objective was to associate PTP1B overexpression with outcomes of breast cancer patients who underwent neoadjuvant chemotherapy. Forty-six specimens were included. Diagnostic biopsies were immunostained using anti-PTP1B antibody. Expression was categorized as negative (<5%) and overexpression (≥5%). Patients' responses were graded according to the Miller-Payne system. Sixty-three percent of patients overexpressed PTP1B. There was no significant association between PTP1B overexpression and pCR ( P = 0.2). However, when associated with intrinsic subtypes, overexpression was higher in human epidermal growth factor receptor 2-positive-enriched specimens ( P = 0.02). Ten-year progression-free survival showed no differences. Our preliminary results do not show an association between PTP1B over-expression and pCR; however, given the limited sample and heterogeneous treatment in our cohort, this hypothesis cannot be excluded.

    We investigated the risk factor of perioperative asthmatic attack and effectiveness of preventing treatment for asthmatic attack before operation. We performed retrospective chart review of one hundred eleven patients with asthma underwent general anesthesia and surgical intervention from January 2006 to October 2007 in our hospital. The rate of perioperative asthmatic attack were as follows; 10.2% (5 in 49 cases) in no pretreatment group, 7.5% (3 in 40 cases) in any pretreatments except for systemic steroid, and 4.5% (1 in 22 cases) in systemic steroid pretreatment group. Neither preoperative asthma severity nor duration from the last attack had significant relevancy to perioperative attack rate. The otolaryngological surgery, especially those have nasal polyp and oral surgery had high perioperative asthma attack rate, although there was no significant difference. We recommend the systemic steroid pretreatment for asthmatic patients, especially when they have known risk factor such as administration of the systemic steroid within 6 months, or possibly new risk factor such as nasal polyp, otolaryngological and oral surgery.

    Roux-en-Y gastric bypass (RYGB) is a highly effective treatment for obesity and results in long-term weight loss and resolution of co-morbidities. However, weight regain may occur as soon as 1-2 years after surgery. This retrospective study aimed to investigate the prevalence of weight regain and possible preoperative predictors of this phenomenon after RYGB. An academic medical center in the United States. A total of 1426 obese patients (15.8% male) who underwent RYGB during January 2000 to 2012 and had at least a 2-year follow-up were reviewed. We included only patients who were initially successful, having achieved at least 50% excess weight loss at 1 year postoperatively. Patients were then categorized into either the weight regain group (WR) or sustained weight loss (SWL) group based upon whether they gained≥15% of their 1-year postoperative weight. Weight regain was observed in 244 patients (17.1%). Preoperative body mass index was similar between groups. Body mass index was significantly higher and percent excess weight loss was significantly lower in the WR group (Pweight regain was 19.5±9.3 kg and-.8±8.5 in the WR and SWL groups, respectively (Pweight loss. Moreover, a longer duration after RYGB was associated with weight regain. Multivariate analysis revealed that younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The present study confirmed that a longer interval after RYGB was associated with weight regain. Younger age was a significant predictor of weight regain even after adjusting for time since RYGB. The findings of this study underscore the complexity of the mechanisms underlying weight loss and regain after RYGB. Future prospective studies are needed to further explore the prevalence, predictors, and mechanisms of weight regain after RYGB. Copyright © 2016 American Society for Bariatric Surgery.

    The aim of this study is to estimate the feasibility of quality of life (QOL) research and to evaluate the QOL prospectively in locally advanced prostate cancer patients treated with hormonal treatment combined with radiotherapy. The treatment schedule was that patients with decreasing prostatic specific antigen (PSA) levels below 10 ng/ml after receiving 6 months of neoadjuvant hormonal treatment were randomly divided into two groups; one group was the continuous hormonal treatment group and the other was the intermittent hormonal treatment group. Both groups received a total dose of 72 Gy external beam radiotherapy with concomitant hormonal treatment followed by 6 months of adjuvant hormonal treatment following radiotherapy. At 14 months, patients either underwent continuous or intermittent hormonal treatment according to the random allocation. QOL was assessed at baseline, and at 6, 8, 14, and 20 months after treatment using functional assessment of cancer treatment-general (FACT-G), P with the other 3 items comprising bother of urination, bother of bowel movement, and bother of sexual activity. Between January 2000 and June 2003, a total of 188 patients were enrolled in this study. The rate of collection of baseline QOL sheets was 98.0%. The rate of answer to questions of QOL sheets was 99.0%. At baseline, the average score of FACT-G, P was 120.7 and the maximum score was more than twice the minimum score. Dysfunction of urination and bowel movement was correlated with the bother of urination and bowel movement, respectively. On the other hand, dysfunction of sexual activity was not correlated with the bother of sexual activity. In June 2003, all of the QOL sheets at baseline, and at 6, 8, and 14 months were completely collected from a total of 72 patients. Although QOL at 8 months was significantly affected compared with QOL at baseline and at 6 months, QOL at 14 months was significantly improved compared with that at 8 months and there was no significant

    We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

    The primary objective of this study was to evaluate the impact of polypharmacy on primary and secondary adherence to evidence-based medication (EBM) and to measure factors associated with non-adherence among patients who underwent percutaneous coronary intervention (PCI). We conducted a retrospective analysis for patients who underwent PCI at a tertiary cardiac care hospital in Qatar. Patients who had polypharmacy (defined as ≥6 medications) were compared with those who had no polypharmacy at hospital discharge in terms of primary and secondary adherence to dual antiplatelet therapy (DAPT), beta-blockers (BB), angiotensin converting enzyme inhibitors (ACEIs) and statins. A total of 557 patients (mean age: 53±10 years; 85%; males) who underwent PCI were included. The majority of patients (84.6%) received ≥6 medications (polypharmacy group) while only 15.4% patients received ≥5 medications (nonpolypharmacy group). The two groups were comparable in term of gender, nationality, socioeconomic status and medical insurance. The non-polypharmacy patients had significantly higher adherence to first refill of DAPT compared with patients in the polypharmacy group (100 vs. 76.9%; p=0.001). Similarly, the non-polypharmacy patients were significantly more adherent to secondary preventive medications (BB, ACEI and statins) than the polypharmacy group. In patients who underwent PCI, polypharmacy at discharge could play a negative role in the adherence to the first refill of EBM. Further studies should investigate other parameters that contribute to long term non-adherence.

    Full Text Available Background: The goals for sedation in pediatric patients scheduled to undergo cardiac catheterization include immobility, analgesia, cardiovascular and respiratory stability. We investigated the effects of Propofol and Ketamine on hemodynamic, respiratory status, sedation level, pain score and recovery period in pediatric patients undergoing cardiac catheterization. Methods: We preformed a randomized clinical trial study on 40 pediatric patients. The patients were randomly assigned to two groups, so that 20 patients received Ketamine and 20 patients received Propofol. In all patients, sedation was started with Midazolam (0.03mg/kg, then followed by Propofol in the first group and Ketamine in the second one. The hemodynamic responses, respiratory parameters, recovery characteristics (Ramsey scale, pain score VAS and relevant adverse effects of the two groups were recorded. Data was analyzed using Paired T Test, ANOVA and Stearman correlation coefficient. Results: Five patients in the Propofol group andon patients in the Ketamine group experienced a transient decrease in mean systolic blood pressure greater than 10% of baseline(p=0.034. Time to full recovery (mean ± SD was not significantly different in the Propofol group and Ketamine group (1.8 min vs. 2.9 min, P > 0.05. Pain scores were significantly different in both groups (P= 0.010. Patients’ heart rates were significantly higher in Ketamine group(P=0.029. No significant difference in respiratory rate was recorded in both groups(p›0.05. Conclusion: Both Ketamine and Propofol are useful and safe in pediatric patients undergoing cardiac catheterization but it seems that it is better to use Propofol in stable hemodynamic pediatric patients under continuous blood pressure monitoring.

    Full Text Available Objective: In our study, we aimed to compare effects of preoperative dexketoprofen and tramadol administered by intravenous route on intraoperative and postoperative analgesic consumption, postoperative pain, durations of hospital stay and patient satisfaction in patients, undergoing laparoscopic cholecystectomy. Methods:After approval of ethic committee and written consent of patients were obtained, 60 patients between 18-70 years old with ASA I-II were included in the study. After routine monitorization and 20 minutes before induction of anesthesia, dexketoprofen 50 mg in 100 cc 0.9% NaCl was administered in Dexketoprofen Group and tramadol 100 mg in 100 cc 0.9% NaCl in Tramadol Group as intravenous infusion during 20 minutes. Intraoperative hemodynamic parameters, analgesic-anesthetic consumptions and complications of patients, on whom standard general anesthesia was applied, were recorded. Pain severity, degree of sedation, morphine consumptions and hemodynamic parameters were recorded at postoperative 30 th minute, and 4 th, 8th, 12th and 24 th hours. Additional analgesia requirement, times for requiring first analgesia, duration of hospital stay, postoperative complications and patient satisfactions were recorded. Results: Intraoperative analgesic-anesthetic consumptions, postoperative visual analogue scale (VAS scores, sedation degrees, intravenous patient controlled analgesia (PCA and morphine consumptions, times for requiring first analgesic, durations of hospital stay, intraoperative-postoperative complications developed and patient satisfactions were similar in both groups. Consequently, postoperative analgesic efficacy of pre-emptive dexketoprofen intravenous 50 mg and tramadol intravenous 100 mg administered was found to be similar in cases, who had laparoscopic cholecystectomy operation. Conclusion:Because VAS scores were low in our patients, morphine consumptions with intravenous PCA were similar in both groups, and there wasn

    Abstract The recurrence rate for acute appendicitis treated nonoperatively varies between studies. Few studies have adequately evaluated the management of these patients when appendicitis recurs. We aimed to explore the recurrence rate and management of patients with acute appendicitis that were first treated nonoperatively. We identified patients in the Taiwan National Health Insurance Research Database who were hospitalized due to acute appendicitis for the first time between 2000 and 2010 and received nonsurgical treatment. The recurrence and its management were recorded. Data were analyzed to access the risk factors for recurrence and factors that influenced the management of recurrent appendicitis. Among the 239,821 patients hospitalized with acute appendicitis for the first time, 12,235 (5.1%) patients were managed nonoperatively. Of these, 864 (7.1%) had a recurrence during a median follow-up of 6.5 years. Appendectomy was performed by an open and laparoscopic approach in 483 (55.9%) and 258 (29.9%) patients, respectively. The remaining 123 (14.2%) patients were again treated nonsurgically. Recurrence was independently associated with young age, male sex, percutaneous abscess drainage, and medical center admission by multivariable analysis. In addition, age appendicitis, percutaneous abscess drainage, nor length of first time hospital stay had an influence on the selection of surgical approach. In conclusion, a laparoscopic appendectomy can be performed in recurrent appendicitis cases, and its application may not be related to previous appendicitis severity. PMID:27015200

    Full Text Available Background: Submucous myomas may be associated with menorrhagia, infertility and dysmenorrhea. Objective: The aim of this study was to determine the long term effects of submucousal myoma resection on menorrhagia and infertility; also to detect whether the type, size, and location of myoma affect the surgical success. Materials and Methods: .Totally 98 women referred to hysteroscopy for symptomatic submucousal fibroids (menorrhagia (n=51 and infertility (n=47 between 2005- 2010 were enrolled in this historical cohort study Pregnancy rates and menstrual improvement rates were compared according to myoma characteristics (size, type and location. Results: After a mean postoperative period of 23±10 months in 51 patients with excessive bleeding, 13 had recurrent menorrhagia (25%. In Other 38 patients excessive bleeding was improved (75%. The improvement rates by location and myoma type: lower segment 100%, fundus 92%, and corpus 63%; type 0 70%, type 1 78%, type 2 80%. The mean sizes of myoma in recurred and improved patients were 23.33 mm and 29.88 mm respectively. 28 of 47 infertile women spontaneously experienced thirty pregnancies (60%. Pregnancy rates according to myoma location and type: lower segment 50%, fundus 57%, and corpus 80%; type 0 75%, type 1 62%, type 2 50%. The mean myoma size in patients who became pregnant was 30.38 mm; in patients who did not conceive was 29.95 mm. Conclusion: The myoma characetesitics do not affect improvement rates after hysteroscopic myomectomy in patients with unexplained infertility or excessive uterine bleeding.

    Due to the recent advances in radiological diagnostic technology, the role of video-assisted thoracoscopic surgery in thoracic disease has expanded, surgical indication extended to the elderly patients. Cancer patients receiving surgery, radiation therapy and/or chemotherapy may encounter complications in conjunction with the oral cavity such as aspiration pneumonia, surgical site infection and various type of infection. Recently, it is recognized that oral health care management is effective to prevent the postoperative infectious complications, especially pneumonia. Therefore, oral management should be scheduled before start of therapy to prevent these complications as supportive therapy of the cancer treatment. In this background, perioperative oral function management is highlighted in the remuneration for dental treatment revision of 2012,and the importance of oral care has been recognized in generally. In this manuscript, we introduce the several opinions and evidence based on the recent previous reports about the perioperative oral health care and management on thoracic surgery.

    Full Text Available Objective: The major factor for developing malignant skin cancers is sunlight exposure. This study aimed to evaluate the demographics of patients with skin cancers who underwent surgery in Diyarbakır where the population is exposed to more sunlight than most other Turkish cities. Methods: The medical records of patients who underwent surgery for malignant skin cancer excision between 2011 and 2016 were searched using University Hospital’s patient database program. Data about patients’ demographics, cancer features, and the surgical techniques performed were collected. Results: Over a 5-year period, 190 patients underwent surgical excision. The male to female ratio was 1.56, and the mean age was 65.8 ± 15.7 (range, 20-94 years. The most common skin cancer was basal cell carcinoma (n=138, 72.7%, followed by squamous cell carcinoma (n=45, 23.7% and malignant melanoma (n=5, 2.6%. The most common surgery was primary excision, which was performed in 90 of 190 patients (47.36%; tissue reconstruction with a skin graft or flap surgery was required for the remaining 100 (52.63%, showing a significant difference (p<0.001. Conclusion: Basal cell carcinoma is the most common skin cancer, and less than half of the patients sought treatment immediately after they recognized the lesion. The public should be educated about skin cancers to increase early diagnosis and encourage timely treatment, thereby decreasing morbidity and mortality from skin cancer.

    Conclusion: In our experience, MACE events were not higher in patients with FFR > 0.8 and kept under medical therapy and were similarly lower in patients with FFR ≤0.8 and underwent revascularisation (p = 0.73. Also MACE events were higher in patients with FFR ≤ 0.8 and did not undergo revascularisation compared to other two appropriately treated groups (p = 0.03. FFR based revascularization decision appears to be a safe strategy in Indian patients.

    To compare the performance of microdose flare-up (MF) and flexible-multidose gonadotropin-releasing hormone (GnRH) antagonist protocols in poor responder patients who underwent intracytoplasmic sperm injection (ICSI). One hundred and 12 consecutive patients (217 cycles) suspected to have poor ovarian response were enrolled. Group 1 (MF GnRH agonist group) constituted 64 patients (135 cycles) who underwent MF GnRH agonist protocol. Group 2 (flexible-multidose GnRH antagonist group) constituted 48 patients (82 cycles) who underwent flexible-multidose GnRH antagonist protocol. The duration of stimulation (d) (11.5 +/- 2.1 vs. 10.4 +/- 2.7, p or = seven blastomeres and < 10% fragmentation at day 3 (35.9% vs. 65.1%, p < 0.05) were significantly lower in Group 1 when compared to Group 2. The number of embryos transferred (2.2 +/- 1.3 vs. 2.4 +/- 0.9), the clinical pregnancy per embryo transfer (16.3% vs. 25.8%), and the implantation rate (8.6% vs. 12.2%) were comparable between groups. Although the flexible-multidose GnRH antagonist protocol produced better oocyte and embryo parameters, the clinical pregnancy rate and the implantation rates were comparable between the flexible-multidose GnRH antagonist and MF protocols in poor responder patients.

Incidence and prognosis of tumor deposits in stage I, II, and III colorectal cancer patients has been explored. The aim of this study was to determine the prognostic value of tumor deposits in stage IV colorectal cancer patients who underwent simultaneous resection for synchronous colorectal liver metastases (SCRLM.Methods: Clinicopathological and outcome data of 146 consecutive SCRLM patients who underwent simultaneous R0 resection between July 2003 and July 2013 were collected from our prospectively established SCRLM database. The prognostic value of tumor deposits was evaluated by Kaplan–Meier and Cox regression analysis.Results: Tumor deposits were detected in 41.8% (61/146 of these SCRLM patients. Tumor deposits were significantly correlated with lymph node metastasis and nerve invasion of the primary tumors (P=0.002, P=0.041; respectively. The Kaplan–Meier survival analysis revealed that the overall survival (OS and disease-free survival (DFS of SCRLM patients with tumor deposits were significantly poorer than those with no tumor deposits (P=0.039, P=0.001; respectively. And with multivariate analysis, we found that positive tumor deposits were significantly associated with shorter DFS independent of lymph node status (P=0.002. Subgroup analysis found that of the 57 SCRLM patients with negative lymph node status, the OS and DFS of patients with positive tumor deposits were significantly shorter than those with negative tumor deposits (P=0.002 and P=0.031, respectively. Of the 89 patients with positive lymph node status, the OS of

    According to current guidelines, in patients without additional risk factors who have undergone aortic valve replacement with a bioprosthesis, anticoagulation in the first 3 months after surgery is still a matter of debate. According to current evidence, aspirin in low doses is a reasonable alternative to vitamin K antagonists (VKA). A comparison is made between the incidence of thrombotic and haemorrhagic complications in patients with low thrombotic risk who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico. The hypothesis: aspirin as monotherapy has a beneficial effect compared to VKA. The studied patients were the low thrombotic risk patients who underwent aortic valve replacement with a bioprosthesis in the National Institute of Cardiology of Ignacio Chávez of Mexico from 2011 to 2015. The groups studied were: aspirin only, VKA only, and the combination of VKA plus aspirin. The patients were retrospectively followed-up for 12 months, and the thrombotic and haemorrhagic complications were documented. Of the 231 patients included in the study, only one patient in the VKA only group presented with a haemorrhagic complication. No thrombotic complications were observed. In the present study no thrombotic complications were observed in patients who did not receive anticoagulation in the first 3 months after an aortic valve replacement with a bioprosthesis after a follow up period of 12 months. This suggests that the use of aspirin only is safe during this period. Copyright © 2017 Instituto Nacional de Cardiología Ignacio Chávez. Publicado por Masson Doyma México S.A. All rights reserved.

    Although multigene panel testing is increasingly common in patients with cancer, the relationship between its use among breast cancer patients with non-BRCA mutations or variants of uncertain significance (VUS) and disease management decisions has not been well described. This study evaluated the rate and predictive factors of CPM patients who underwent multigene panel testing. Three hundred and fourteen patients with breast cancer who underwent multigene panel testing between 2014 and 2017 were included in the analysis. Of the 314 patients, 70 elected CPM. Election of CPM by gene status was as follows: BRCA carriers (42.3%), non-BRCA carriers (30.1%), and VUS (10.6%). CPM election rates did not differ between non-BRCA carriers and BRCA carriers (P = 0.6205). Among non-BRCA carriers, negative hormone receptor status was associated with CPM (P = 0.0115). For those with a VUS, hormone receptor status was not associated with CPM (P = 0.1879). Although the rate of CPM between BRCA carriers and non-BRCA carriers was not significantly different, the predictors of CPM were different in each group. Our analyses shed the light on the increasing use of CPM among patients who are non-BRCA carriers as well those with a VUS. Our study elucidates the differing predictive factors of CPM election among BRCA carriers, non-BRCA carries, and those with a VUS. Our findings reveal the need for providers to be cognizant that non-BRCA genes and VUS drive women to elect CPM despite the lack of data for contralateral breast cancer risk associated with these genes. © 2018 The Authors.

    Although the numeric-based lymph node (LN) staging was widely used in the worldwide, it did not represent the anatomical location of metastatic lymph nodes (MLNs) and not reflect extent of LN dissection. Therefore, in the present study, we investigated whether the anatomical location of MLNs was still necessary to evaluate the prognosis of node-positive gastric cancer (GC) patients. We reviewed 1451 GC patients who underwent radical gastrectomy in our institution between January 1986 and January 2008. All patients were reclassified into several groups according to the anatomical location of MLNs and the number of MLNs. The prognostic differences between different patient groups were compared and clinicopathologic features were analyzed. In the present study, both anatomical location of MLNs and the number of MLNs were identified as the independent prognostic factors (p location of MLNs was considered (p location of MLNs had no significant effect on the prognosis of these patients, the higher number of MLNs in the extraperigastric area was correlated with the unfavorable prognosis (p location of MLNs was an important factor influencing the prognostic outcome of GC patients. To provide more accurate prognostic information for GC patients, the anatomical location of MLNs should not be ignored.

    Full Text Available Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS. Three main components (naringin, naringenin, and hesperetin were isolated from C. aurantium. Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory function on cell growth. ROS production was increased in naringin- and hesperetin-treated groups after one day of culture while the level was always lowest in the naringenin-treated group after three days of culture. 95 osteosarcoma patients who underwent surgery were assigned into two groups: naringenin group (NG, received 20 mg naringenin daily, n=47 and control group (CG, received 20 mg placebo daily, n=48. After an average of two-year follow-up, osteosarcoma volumes were smaller in the NG group than in the CG group (P>0.01. The rate of osteosarcoma recurrence was also lower in the NG group than in CG group. ROS levels were lower in the NG group than in the CG group. Thus, naringenin from Citrus aurantium inhibits osteosarcoma progression and local recurrence in the patients who underwent osteosarcoma surgery by improving antioxidant capability.

    Full Text Available Background: The aim of the study was to determine the correlation between clinical and echocardiographic findings and risk factors of patients with suspected acute pulmonary thromboembolism (PTE who underwent computed tomography pulmonary angiography (CTPA. Materials and Methods: In this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of PTE referred to imaging center of our hospital from different wards for CTPA were enrolled. The frequency of different clinical presentations, risk factors, items of Wells' criteria, and echocardiographic findings was compared in patients with and without PTE, which have been diagnosed according to the CTPA results. Results: PTE was diagnosed in 53 (17.1% of patients with suspected PTE. From clinical manifestations, tachypnea, pleuritic chest pain, and edema of lower extremities were significantly more frequent among patients with PTE (P < 0.05. Major surgery was the risk factor which was significantly more prevalent among patients with PTE (P < 0.05. Frequency of all criteria of Wells' criteria, except hemoptysis, was significantly higher in patients with PTE (P < 0.05. The frequency of all studied echocardiographic variables was significantly higher in patients with PTE (P < 0.05. Conclusion: It is suggested that we could use the results of this study for utilizing the diagnostic process of PTE in patients with highly clinical suspicion of PTE and providing more validated decision. Using the results of this study, we could identify high-risk patients and made appropriate risk assessment for better management of patients with suspected PTE as well as reduce the rate of unnecessary CTPA and its related adverse consequences.

    The aim of this retrospective study was to evaluate the accuracy of bone SPECT (single photon emission computed tomography)/CT (computed tomography) in diagnosing loosening of fixation material in patients with recurrent or persistent back pain that underwent lumbar arthrodesis with pedicle screws using surgery and clinical follow-up as gold standard A total of 48 patients (median age 49 years, range 21-81 years; 17 men) who had undergone lumbar spinal arthrodesis were included in this retrospective analysis. SPECT/CT results were compared to the gold standard of surgical evaluation or clinical follow-up. Positive SPECT/CT results were considered true positives if findings were confirmed by surgery or if clinical and other examinations were completely consistent with the positive SPECT/CT finding. They were considered false positives if surgical evaluation did not find any loose pedicle screws or if symptoms subsided with non-surgical therapy. Negative SPECT/CT scans were considered true negatives if symptoms either improved without surgical intervention or remained stable over a minimum follow-up period of 6 months. Negative SPECT/CT scans were determined to be false negatives if surgery was still required and loosening of material was found. The median length of time from primary surgery to bone SPECT/CT referral was 29.5 months (range 12-192 months). Median follow-up was 18 months (range 6-57) for subjects who did not undergo surgery. Thirteen of the 48 patients were found to be positive for loosening on bone SPECT/CT. Surgical evaluation (8 patients) and clinical follow-up (5 patients) showed that bone SPECT/CT correctly predicted loosening in 9 of 13 patients, while it falsely diagnosed loosening in 4 patients. Of 35 negative bone SPECT/CT scans, 12 were surgically confirmed. In 18 patients, bone SPECT/CT revealed lesions that could provide an alternative explanation for the symptoms of pain (active facet degeneration in 14 patients, and disc and sacroiliac

    Full Text Available The role of decompressive craniectomy in the treatment of severe posttraumatic cerebral swelling remains quite a controversial issue. To the best of our knowledge, there is no study demonstrating the effect of decompressive craniectomy on cerebral blood flow (CBF velocity by means of transcranial Doppler sonography (TCD. We present two patients who developed traumatic brain swelling and uncontrollable intracranial hypertension with coma and signs of transtentorial herniation. One patient underwent bifrontal, while the second, unilateral, frontotemporoparietal decompressive craniectomy with dural expansion. In both patients, TCD examinations were performed immediately before and after surgery to study the cerebral hemodynamic changes related to the operations. Pre and postoperative TCD examinations demonstrated a significant increase in blood flow velocity in the intracranial arteries in both subjects. In conclusion, our cases suggest that decompressive craniectomy with dural expansion may result in elevation of CBF velocity in patients with massive brain swelling. The increase in CBF velocity appears to occur not only in the decompressed hemisphere, but also on the opposite side.

    The purpose of this paper is to demonstrate the effect of the transfusion of blood received 1500 rad exposure upon the immune response in 14 patients underwent various type of cardiac surgery. 13 patients received known amounts banked blood and irradiated fresh blood, while one patient received a lot of amounts of banked and irradiated and non-irradiated fresh blood. The authors studied the numbers of lymphocytes as well as lymphocyte subsets such as pan-T cells, B cells, helper/inducer T cells (T H/I ), cytotoxic/supressor T cells (T C/S ), active T cells, natural killer (NK) cells and NK cell activity during two weeks after surgeries. In all 14 patients, pan-T lymphocytes decreased markedly in a few days after surgeries, but increased to higher levels on the eight postoperative day than the levels preoperatively. T H/I and T C/S lymphocytes changed on the similar pattern as pan-T lymphocytes. Active T and B cells did not change significantly in two weeks. The number and activity of NK cells gave the lowest levels on the second postoperative day and did not recovery to the preoperative levels in two weeks. One patient received non-irradiated fresh blood showed the similar immune response as other 13 patients, while he gave the lower levels than others did. This patient died of graft-versus-host disease (GVHD)-like syndrome on the 36th postoperative day. It may be thought that the transfusion of irradiated blood would prevent the host from GVHD and gave the better effects on the immune response than that of non-irradiated blood following open-heart surgeries.

    Full Text Available Abstract Background There is no consensus regarding the management of ovarian cancer patients, who have shown complete clinical response (CCR to primary therapy and have rising cancer antigen CA-125 levels but have no symptoms of recurrent disease. The present study aims to determine whether follow-up CA-125 levels can be used to identify the need for imaging studies and secondary cytoreductive surgery (CRS. Methods We identified 410 ovarian cancer patients treated at The University of Texas MD Anderson Cancer Center between 1984 and 2011. These patients had shown CCR to primary therapy. Follow-up was conducted based on the surveillance protocol of the MD Anderson Cancer Center. We used the Cox proportional hazards model and log-rank test to assess the associations between the follow-up CA-125 levels and secondary CRS and survival duration. Results The CA-125 level of 1.68 × nadir was defined as the indicator of recurrent disease (p  1.68 × nadir at relapse (55.7 and 10.4 months; p = 0.04 and 0.01, respectively. The overall and progression free survival duration of patients with asymptomatic relapse and underwent a secondary CRS was longer than that of patients with symptomatic relapse (p = 0.02 and 0.04 respectively. Conclusions The increase of serum CA-125 levels is an early warning of clinical relapse in ovarian cancer. Using CA-125 levels in guiding the treatment of patients with asymptomatic recurrent ovarian cancer, who have shown CCR to primary therapy, can facilitate optimal secondary CRS and extend the survival duration of the patients.

    To compare the periodical incidence rates of genitourinary (GU) and gastrointestinal (GI) toxicity in patients who underwent prostate low-dose-rate brachytherapy between the monotherapy group (seed implantation alone) and the boost group (in combination with external beam radiation therapy (EBRT)). A total of 218 patients with a median follow-up of 42.5 months were enrolled. The patients were divided into 2 groups by treatment modality, namely, the monotherapy group (155 patients) and the boost group (63 patients). The periodical incidence rates of GU and GI toxicity were separately evaluated and compared between the monotherapy group and the boost group using the National Cancer Institute - Common Terminology Criteria for Adverse Events, version 3.0. To elucidate an independent factor among clinical and postdosimetric parameters to predict grade 2 or higher GU and GI toxicity in the acute and late phases, univariate and multivariate logistic regression analyses were carried out. Of all patients, 78.0% showed acute GU toxicity, and 7.8% showed acute GI toxicity, while 63.8% showed late GU toxicity, and 21.1% showed late GI toxicity. The incidence rates of late GU and GI toxicity were significantly higher in the boost group. Multivariate analysis showed that the International Prostate Symptom Score (IPSS) before seed implantation was a significant parameter to predict acute GU toxicity, while there were no significant predictive parameters for acute GI toxicity. On the other hand, combination with EBRT was a significant predictive parameter for late GU toxicity, and rectal volume (mL) receiving 100% of the prescribed dose (R100) was a significant predictive parameter for late GI toxicity. The boost group showed higher incidence rates of both GU and GI toxicity. Higher IPSS before seed implantation, combination with EBRT and a higher R100 were significant predictors for acute GU, late GU and late GI toxicity

    Patients who underwent resection of maxilla due to benign or malignant tumor, or accident will have defect in palatal area. They get retention, support and stability from remaining tissues which are hardly optimal. The advantage of swing-lock attachment design is having multiple contacts on labial and lingual side of the abutment teeth by retentive strut and palatal bracing component. Because the force is distributed equally to abutment teeth, abutment teeth of poor prognosis can be benefited from it. It is also more advantageous to cover soft tissue defects which are hard to reach with conventional prosthesis. A 56-year-old female patient who had undergone a maxillectomy due to malignant melanoma complaining of loose and unstable surgical obturator. Surveyed crowns were placed on #12, 26, and 27. Teeth #11, 21, 22, and 23 had lingual rest seat and #24 had mesial rest seat to improve stability and support of the obturator. This clinical report presents the prosthetic management of a patient treated with obturator on the maxilla using swing-lock attachment to the remaining teeth. PMID:27826392

The serum testosterone concentration should be IA) has become widespread, although their metrological characteristics do not seem appropriate for quantifying low testosterone concentrations. The objective of this review is to analyse the methods for quantifying testosterone and to establish whether there is scientific evidence that justifies measuring it in patients with PC who undergo castration, through liquid chromatography attached to a mass spectrometry in tandem (LC-MSMS). We performed a search in PubMed with the following MeSH terms: measurement, testosterone, androgen suppression and prostate cancer. We selected 12 studies that compared the metrological characteristics of various methods for quantifying serum testosterone compared with MS detection methods. IAs are standard tools for measuring testosterone levels; however, there is evidence that IAs lack accuracy and precision for quantifying low concentrations. Most chemiluminescent IAs overestimate their concentration, especially below 100ng/dL. The procedures that use LC-MSMS have an adequate lower quantification limit and proper accuracy and precision. We found no specific evidence in patients with PC who underwent castration. LC-MSMS is the appropriate method for quantifying low serum testosterone concentrations. We need to define the level of castration with this method and the optimal level related to better progression of the disease. Copyright © 2017 AEU. Publicado por Elsevier España, S.L.U.

    Full Text Available Introduction: Quality of life can be defined as the expression of aconceptual model that tries to represent patient’s perspectivesand his/her level of satisfaction expressed by numbers. Theobjective of this study is to evaluate the parameters of quality oflife of 23 patients who underwent surgery for anterior cruciateligament reconstruction. Methods: We adopted SF-36, a generichealth-related evaluation questionnaire, to obtain informationregarding several aspects of patients’ health conditions, and theLysholm questionnaire, specific to evaluate the symptoms andfunction of the knee. The questionnaires were applied at two stagesof the treatment: pre- and postoperatively (after the rehabilitationprogram. Results: Before surgery, the Lysholm questionnairepresented the following results: excellent in 4% of the cases, goodin 22%, fair in 22%, and poor in 52%. After surgery (Lysholm e SF-36 the correlation level was approximately 44% (p = 0.041.Discussion: The correlation between the Lysholm and the SF-36questionnaires showed the following: the lower the level of pain,the higher the Lysholm score. The high scores presented by theLysholm questionnaire are directly proportional to physical andemotional aspects, and to functional capacity. Conclusion:Analysis of both questionnaires, as well as of their correlation,showed some improvement in patients´ quality of life. We werealso able to demonstrate the importance and usefulness of applyingthe two questionnaires at three different moments: before, duringand after physiotherapeutic intervention.

    Serum C reactive protein (CRP) has been shown to be associated with the progression of esophageal cancer. The purpose of this study was to examine the relationship between treatment response and serum CRP levels in time course during definitive chemoradiotherapy (CRT) in terms of early prediction of CRT response by serum CRP. The subjects of this study were 36 patients with cT3/cT4 esophageal squamous cell carcinoma who underwent definitive CRT in our hospital. Serum CRP levels during definitive CRT (pretreatment, 1W, 2W and 3W after CRT initiation) were compared between CR and non-CR group. In addition, partition model was constructed to discriminate CR with non-CR and the prediction accuracy was evaluated. The patients were consisted of 28 males and 8 females. At pretreatment diagnosis, tumors were categorized as T3 (n=21) and T4 (n=15). Thirty four patients received FP-based chemotherapy and 2 patients received docetaxel-based chemotherapy. Treatment responses were categorized as CR (n=8), partial response (PR) (n=14), no change (NC) (n=2) and progressive disease (PD) (n=12). Serum CRP levels at the time of 2W after CRT initiation (CRT2W) in CR group were low compared to those in non-CR group (p=0.071). The partition model was constructed based on CRP levels at CRT2W. The prediction accuracies to discriminate CR from non-CR by CRP ≤0.1 were 50%, 82%, and 75% in sensitivity, specificity and accuracy, respectively. Serum CRP is a useful biomarker for an early prediction of CRT response. (author)

    Full Text Available Echocardiography in coronary artery diseases is an essential, routine echocardiography prior to primary percutaneous angioplasty is not clear. In our clinical practice in primary angioplasty we faced lots of complications either before or during or after the procedure. Moreover, lots of incidental findings that discovered after the procedure which if known will affect the plan of management. One-hundred-nineteen consecutive underwent primary angioplasty. All patients underwent FE prior to the procedure in catheterization lab while the patient was preparing for the procedure. FE with 2DE of LV at base, mid and apex, and apical stander views.

    In order to evaluate the changes in biochemical liver function tests and hepatic scintigraphic findings of chronic hepatitis, the author analyzed 35 patients who underwent serial liver biopsies. The results were summerized as follows: 1. Histological deteriorations in chronic hepatitis more inclined to be presented in the scintigraphic abnormalities such as the increased uptake of radioisotope in the spleen and bone marrow than the deteriorations in biochemical liver function tests. Moreover, the increased radioisotope uptake by spleen and bone marrow in hepatic scintigram highly correlated with histological deteriorations. On the other hand, in the cases with histological improvement no scintigraphic improvement was ovserved. 2. Comparing the changes in the result of liver function tests with histological features, biochemical deteriorations significantly correlated with histological deteriorations, although biochemical improvements were not reliable indicators of histological improvements. 3. Changes in biochemical parameters such as serum GOT, GPT, albumin, γ-globulin, TTT and ALP were analyzed by means of Hayashi's second method of quantification and predictive values for histological feactures were calculated. As a result, histological deteriorations were predicted in 89.5% of the cases, but histological improvements were predicted only in 66.7%. In the various biochemical parameters, γ-globulin was considered as most important in predicting histological features and ALP was ranked the second. (J.P.N.)

    The myocardial uptake and redistribution in thallium scintigraphy and the regional wall motion by echocardiography were evaluated by a semi-quantitative method in 42 patients who previously had myocardial infarction (50 target vessels) and underwent coronary revascularization. The aim of this study was to elucidate the significance of the initial image, delayed image and redistribution on thallium-201 scintigraphy for clinical diagnosis of the myocardial viability. As a semi-quantitative analysis, we used a bull's-eye display for thallium image and centerline method for echocardiographic wall motion, and compared the results before and after revascularization. As a result, the thallium grade improved postoperatively in all 17 areas which preoperatively had showed redistribution, and also in 11 of the 32 areas without preoperative redistribution. The sensitivity, specificity and accuracy of preoperative thallium redistribution for predicting myocardial viability were 61%, 100% and 78%, respectively, when the postoperative improvement in the thallium grade was used as the standard. The postoperative probability of improvement in the thallium grade increased in proportion to the preoperative grade (delayed image)(p<0.01). There was no correlation between the preoperative thallium delayed image and postoperative improvement in wall motion. Postoperative improvement in thallium image and wall motion could not be predicted from the preoperative wall motion. Thus, postoperative improvement in thallium images can be anticipated if redistribution is present on the preoperative thallium image, and the preoperative thallium delayed image is useful for predicting myocardial viability. Improvement in wall motion could not be predicted preoperatively by these methods. (author)

    Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response

    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.

    The aim of the present study is to assess the long-term effect of classic rhinoplasty on patients' quality of life. Outcomes research. The study included 100 operated patients; there were 34 males and 66 females. The ages ranged between 23 and 57 years old, with a mean of 36.4 years. A minimum of 3 years between the operation and the study was selected to assess the long-term effect of the operation on the patients' quality of life and exclude any short-term impressions. The time elapsed between surgery and the time of the study ranged from 3 to 13 years, with a mean of 6.8 years. Patients were assessed using the Glasgow Benefit Inventory, which has been proven valid and reliable in ear, nose, and throat interventions. From the 100 patients included in the study, 92 reported improvement in their quality of life due to the operation and only eight worsening. In the social support subscale, 97 patients reported better quality of life, and only three patients reported worse quality of life. The patients' overall life markedly improved, reaching a mean of 80% in the Glasgow Benefit Inventory. The present long-term study using a validated and reliable instrument concludes that rhinoplasty improves the quality of life of patients in all sectors. 2c Laryngoscope, 127:2017-2025, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

    Patients treated with antithrombotic therapy that require abdominal surgical procedures has progressively increased overtime. The management of antithrombotics during both the peri- and post- operative period is of crucial importance. The goal of this review is to present current data concerning the management of antiplatelets in patients with coronary artery disease and of anticoagulants in patients with atrial fibrillation who had to undergo abdominal surgical operations. For this purpose, incidence of major adverse cardiovascular events (MACE) and risk of antithrombotic use during surgical procedures, as well as the recommendations based on recent guidelines were reported. A thorough search of PubMed, Scopus and the Cochrane Databases was conducted to identify randomized controlled trials, observational studies, novel current reviews, and ESC and ACC/AHA guidelines on the subject. Antithrombotic use in daily clinical practice results to two different pathways: reduction of thromboembolic risk, but a simultaneous increase of bleeding risk. This may cause a therapeutic dilemma during the perioperative period. Nevertheless, careless cessation of antithrombotics can increase MACE and thromboembolic events, however, maintenance of antithrombotic therapy may increase bleeding complications. Studies and current guidelines can assist clinicians in making decisions for the treatment of patients that undergo abdominal surgical operations while on antithrombotic therapy. Aspirin should not be stopped perioperatively in the majority of surgical operations. Determining whether to discontinue the use of anticoagulants before surgery depends on the surgical procedure. In surgical operations with a low risk for bleeding, oral anticoagulants should not be discontinued. Bridging therapy should only be considered in patients with a high risk of thromboembolism. Finally, patients with an intermediate risk for thromboembolism, management should be individualized according to patient

    Spinal kyphotic deformity occasionally results in gastroesophageal reflux disease (GERD). The effects of acid reflux on the esophagus in kyphotic patients are unclear, however, and it is unknown whether acid reflux, endoscopic GERD, and reflux-related symptoms improve following surgical spinal correction in these patients. Herein, we investigated the characteristics of GERD in kyphotic patients and the improvement in GERD following surgical correction. In 48 patients with severe kyphotic deformity scheduled for surgical spinal correction, we conducted esophagogastroduodenoscopy, 24-h pH monitoring and three questionnaire surveys, including the frequency scale for the symptoms of GERD (FSSG). We repeated these measurements after surgical correction and compared pre- and post-surgery values. Of 48 patients, 70.8% [95% CI: 55.9-83.0%, 34/48] had endoscopically evaluated esophageal mucosal injury. Regarding pH before surgery, 64.9% (CI: 47.5-79.8%, 24/37) had abnormal acid reflux (intraesophageal pH reflux decreased from 66.7% (95% CI: 41.0-86.7%) to 33.3% (95% CI: 13.3-59.0%) (P = 0.045). Surgical spinal correction in kyphosis patients improves not only kyphotic deformity-related disorders but also esophageal mucosal injury, abnormal acid reflux, and reflux-related symptoms. © 2015 Japan Gastroenterological Endoscopy Society.

    Full Text Available Patological disorders within oral mucosa (so called mucositis are the most common stomatological complications among chemotherapy treated leukemic patients scheduled for bone marrow transplantation. Early diagnosis of such oral disorders leads to numerous side effects, decreasing quality of life and systemic complications is required. Furthermore, most patients require analgesic treatment, very often using narcotic pain medications. Presently the largest role of prevention and treatment of mucositis is preventative dentistry along with maintaining strict oral hygiene. This course of action aims to reduce pain and prevention of infections. Investigation of novel non-invasive therapeutic methods that could improve treatment outcomes seems justified. Among the most promising methods, the Low-level Laser Therapy (LLLT treatment demonstrates many beneficial effects for patients suffering from chemotherapy complications. It promotes mucosal healing and helps improve patients' quality of life. These advantages may be a result of a LLLT anti-inflammatory and analgesic effect. LLLT also promotes tissue regeneration through chemical changes in cells (cell repair. In recent clinical studies conducted on a group of patients with oral mucositis, the significant acceleration of mentioned disorders regression was noted. Moreover, reduction of pain after application of LLLT was recorded. Discussed in the article LLLT is easily accessible for clinical practice . Mentioned arguments justify a wider use of such a tool in non-invasive treatment of acute oral cavity inflammation.

    Full Text Available Background: Due to the presence of radiosensitive organs in the abdominopelvic region and increasing the number of requests for CT scan examinations, concerns about increasing radiation doses in patients has been greatly elevated. Therefore, the goal of this study was to determine the absorbed dose of radiosensitive organs and the effective dose in patients underwent abdominopelvic CT scan using ImPACT CT patient dosimetry Calculator (version 1.0.4, Imaging Performance Assessment on Computed Tomography, www.impactscan.org. Methods: This prospective cross-sectional study was conducted in Imam Reza Hospital from November to February 2015 February 2015 in the Imam Reza Hospital, in Urmia, Iran. The demographic and dosimetric information of 100 patients who underwent abdominopelvic CT scan in a 6-slice CT scanner were obtained through the data collection forms. The demographic data of the patients included age, weight, gender, and BMI. The dosimetric parameters included pitch value, CT dose volume index (CTDIvol, dose-length product (DLP, tube voltage, tube current, exposure time, collimation size, scan length, and scan time. To determine the absorbed dose of radiosensitive organs and also the effective dose in patients, ImPACT CT patient dosimetry calculator was used. Results: The results of this study demonstrated that the mean and standard deviation (SD of patients' effective dose in abdominopelvic CT scan was 4.927±0.164 mSv. The bladder in both genders had the greatest mean organ dose, which was 64.71±17.15 mGy for men and 77.56±18.48 mGy for women (P<0.001. Conclusion: The effective dose values of this examination are in the same range as previous studies, as well as International Commission on Radiological Protection (ICRP recommendations. However, the radiation dose from CT scan has the largest contribution to the medical imaging. According to the ALARA principle, it is recommended that the scan parameters, especially mAs, should be

    Natural killer T (NKT) cells are involved in the antitumor response by direct cytotoxicity and indirectly through activation of effector cells. Recent studies have shown a relationship between the number and function of NKT cells and clinical outcomes. NKT cells seem to represent a promising tool for immunotherapy of cancer. The aim of the study was to evaluate the distribution of NKT cells in peripheral blood, lymph nodes and tumor tissue of non-small cell lung cancer (NSCLC) patients, as well as development of the most efficient set of cytokines stimulating differentiation of NKT cells. We evaluated the percentage of iNKT+CD3+ cells in the tissues collected from patients with NSCLC. For the generation of NKT cells, we cultured cells isolated from the blood of 20 healthy donors and from the tissues of 4 NSCLC patients. Cells were stimulated with α-GalCer in combinations with cytokines. We noted significant differences in the percentages of NKT cells in the patients' tissues. The highest percentage of these cells was observed in the tumor tissue and the lowest in the lymph nodes. In vitro, in healthy donors all α-GalCer-cytokine combinations were effective in stimulation of NKT cells' proliferation. NKT cells' proliferation was the most efficiently stimulated by α-GalCer+IL-2+IL-7 and α-GalCer+IL-2+IFN-γ. Our results suggest that in the course of NSCLC, NKT cells migrate to the primary tumor and accumulate therein. All tested combinations of α-GalCer and cytokines were capable of generation of NKT cells in vitro.

The aim of the study was to estimate the impact of whole body cryotherapy (WBC on oxidative stress when performed in a closed cryochamber on patients with ankylosing spondylitis (AS. Material and methods. The effect of ten WBC procedures lasting 3 minutes a day with a subsequent 60-minute session kinesiotherapy on oxidative stress in male AS patients (WBC group n=16 was investigated. To assess the disease activity, the Bath Ankylosing Spondylitis Diseases Activity Index (BASDAI and Bath Ankylosing Spondylitis Functional Index (BASFI were calculated. The WBC group was compared to the kinesiotherapy only (KT; n=16 group. The routine parameters of oxidative stress (antioxidant enzymatic and nonenzymatic antioxidant status, lipid peroxidation products, total oxidative status (TOS, and oxidative stress index (OSI were estimated one day before the beginning and one day after the completion of the research program. Results. After the completion of the treatment in the WBC group, a significant decrease of oxidative stress markers (TOS and OSI and a significant increase of total antioxidant status were observed. The erythrocyte activity of glutathione peroxidase, glutathione reductase decreased significantly in both groups, but the differences of activity of that enzymes prior to post treatment values (Δ in the KT group were significantly higher as compared to the WBC group. The activity of erythrocyte catalase and plasma ZnCu isoenzyme of superoxide dismutase showed a decreased tendency; erythrocyte total superoxide dismutase activity showed an increased tendency in the WBC group after the completion of the treatment. The BASDAI and BASFI decreased significantly in both groups, but the differences of value indexes prior to post treatment (Δ were significantly higher in the WBC than KT group. Conclusion. WBC performed in a closed cryochamber decreases oxidative stress and improves BASDAI and BASFI indexes in male patients during the active

    Purpose: Stereotactic radiosurgery for spine metastases involves irradiation using a single high dose fraction. The purpose of this study was to dosimetrically compare stereotactic spine radiosurgery(SRS) plans using a recently new volumetric modulated arc therapy(VMAT) technique against fix-field intensity-modulated radiotherapy(IMRT). Plans were evaluated for target conformity and spinal cord sparing. Methods: Fifteen previously treated patients were replanned using the Eclipse 10.1 TPS AAA calculation algorithm. IMRT plans with 7 fields were generated. The arc plans used 2 full arc configurations. Arc and IMRT plans were normalized and prescribed to deliver 16.0 Gy in a single fraction to 90% of the planning target volume(PTV). PTVs consisted of the vertebral body expanded by 3mm, excluding the PRV-cord, where the cord was expanded by 2mm.RTOG 0631 recommendations were applied for treatment planning. Partial spinal cord volume was defined as 5mm above and below the radiosurgery target volume. Plans were compared for conformity and gradient index as well as spinal cord sparing. Results: The conformity index values of fifteen patients for two different treatment planning techniques were shown in table 1. Conformity index values for 2 full arc planning (average CI=0.84) were higher than that of IMRT planning (average CI=0.79). The gradient index values of fifteen patients for two different treatment planning techniques were shown in table 2. Gradient index values for 2 full arc planning (average GI=3.58) were higher than that of IMRT planning (average GI=2.82).The spinal cord doses of fifteen patients for two different treatment planning techniques were shown in table 3.

    Introduction: Our aim was to perform a comparative study of short-term cardiovascular autonomic control in cardiac surgery patients who underwent coronary artery bypass grafting (CABG) or surgical correction of valvular heart disease (SCVHD ). Methods: The synchronous 15 minutes records of heart rate variability (HRV) and finger's photoplethysmographic waveform variability (PPGV) were performed in 42 cardiac surgery patients (12 women) aged 61.8 ± 8.6 years (mean ± standard deviation), who underwent CABG, and 36 patients (16 women) aged 54.2 ± 14.9 years, who underwent SCVHD , before surgery and in 5-7 days after surgery. Conventional time and frequency domain measures of HRV and index S of synchronization between the slow oscillations in PPGV and HRV were analyzed. We also calculated personal dynamics of these indices after surgery. Results: We found no differences ( Р > 0.05) in all studied autonomic indices (preoperative and post-surgery) between studied patients' groups, except for the preoperative heart rate, which was higher in patients who underwent SCVHD ( P = 0.013). We have shown a pronounced preoperative and post-surgery variability (magnitude of inter-quartile ranges) of all autonomic indices in studied patients. In the cluster analysis based on cardiovascular autonomic indices (preoperative and post-surgery), we divided all patients into two clusters (38 and 40 subjects) which did not differ in all clinical characteristics (except for the preoperative hematocrit, P = 0.038), index S, and all post-surgery HRV indices. First cluster (38 patients) had higher preoperative values of the HR, TP, HF, and HF%, and lower preoperative values of the LF% and LF/HF. Conclusion: The variability of cardiovascular autonomic indices in on-pump cardiac surgery patients (two characteristic clusters were identified based on preoperative indices) was not associated with their clinical characteristics and features of surgical procedure (including cardioplegia).

    High tibial osteotomy (HTO) is a surgical procedure used to correct abnormal mechanical loading of the knee joint; additionally, intra-articular hyaluronic acid injections have been shown to restore the viscoelastic properties of synovial fluid and balance abnormal biochemical processes. It was hypothesized that combining HTO with intra-articular hyaluronic acid injections would have benefit to improve the cartilage volume of knee joints. Forty patients with medial compartment knee osteoarthritis (OA) were randomly placed into 1 of 2 groups. The study group (n = 20) received 2 cycles (at 6-month intervals) of 5 weekly intra-articular hyaluronic acid injections after HTO operation. The control group (n = 20) did not receive any intra-articular injections after HTO surgery. Cartilage volume (primary outcome) was assessed by magnetic resonance imaging (MRI) pre-operatively and 1 year post-operatively. Treatment efficacy (secondary outcomes) was evaluated with the Western Ontario and McMaster Universities OA Index (WOMAC) and by the comparison of the total rescue medication (paracetamol/diclofenac) used (weeks 6, 12, 24, 48). MRI studies showed a significant increase in total cartilage volume (p = 0.033), lateral femoral cartilage volume (p = 0.044) and lateral tibial cartilage volume (p = 0.027) in the study group. Cartilage volume loss was detected at the lateral tibial plateau in the control group. There were significant improvements after surgery in both groups for all subscales of WOMAC scores (p hyaluronic acid injections may be beneficial for increasing total cartilage volume and preventing the loss of lateral tibiofemoral joint cartilage after HTO.

    To compare the PSA value at the last follow-up of patients who underwent prostate low-dose rate brachytherapy (LDR-BT) with that of patients who underwent intensity-modulated radiation therapy (IMRT). A total of 610 prostate cancer patients (cT1c-3bN0M0) were enrolled, and 445 of them underwent LDR-BT, while 165 received IMRT (74-76 Gy). The median follow-up period of these two groups was 75 months (LDR-BT) and 78 months (IMRT), respectively. We also evaluated the biochemical recurrence (BCR)-free rate using two definitions (Phoenix definition and PSA ≥ 0.2 ng/mL). The percentage of patients who achieved PSA LDR-BT group and 49.7% in the IMRT group (p LDR-BT group and 32.1% in the IMRT group (p LDR-BT groups was 89.5 and 95.0% (p LDR-BT groups, respectively (p LDR-BT was significantly lower than that of IMRT, and this result was particularly marked in patients with a normal testosterone level at the last follow-up.

    The influence of preinfarction angina pectoris (AP) on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) remains controversial. In 5,429 patients with acute myocardial infarction (AMI) enrolled in the Coronary Revascularization Demonstrating Outcome Study in Kyoto AMI Registry, the present study population consisted of 3,476 patients with STEMI who underwent primary PCI within 24 hours of symptom onset and in whom the data on preinfarction AP were available. Preinfarction AP defined as AP occurring within 48 hours of hospital arrival was present in 675 patients (19.4%). Patients with preinfarction AP was younger and more often had anterior AMI and longer total ischemic time, whereas they less often had history of heart failure, atrial fibrillation, and shock presentation. The infarct size estimated by peak creatinine phosphokinase was significantly smaller in patients with than in patients without preinfarction AP (median [interquartile range] 2,141 [965 to 3,867] IU/L vs 2,462 [1,257 to 4,495] IU/L, p <0.001). The cumulative 5-year incidence of death was significantly lower in patients with preinfarction AP (12.4% vs 20.7%, p <0.001) with median follow-up interval of 1,845 days. After adjusting for confounders, preinfarction AP was independently associated with a lower risk for death (hazard ratio 0.69, 95% confidence interval 0.54 to 0.86, p = 0.001). The lower risk for 5-year mortality in patients with preinfarction AP was consistently observed across subgroups stratified by total ischemic time, initial Thrombolysis In Myocardial Infarction flow grade, hemodynamic status, infarct location, and diabetes mellitus. In conclusion, preinfarction AP was independently associated with lower 5-year mortality in patients with STEMI who underwent primary PCI. Copyright © 2014 Elsevier Inc. All rights reserved.

    Periprocedural myocardial injury (PMI) is a major complication of percutaneous coronary intervention (PCI) and is associated with atherosclerotic coronary plaque and worse clinical outcomes. High-density lipoprotein cholesterol (HDL-C) is a protective factor for cardiovascular disease. However, the role of HDL-C subfractions, such as HDL2 cholesterol (HDL2-C) or HDL3 cholesterol (HDL3-C), in cardiovascular disease remains unclear. The purpose of the study was to investigate the relationship between HDL2-C and HDL3-C subfractions and the incidence of PMI in patients who underwent elective PCI. We enrolled 129 patients who underwent elective PCI for stable angina pectoris. PMI was defined as an increase in high-sensitivity troponin T levels > 5 times the upper normal limit (> 0.070 ng/mL) at 24 h after PCI. Serum HDL-C subfractions (HDL2-C and HDL3-C) were assessed using ultracentrifugation in patients with and those without PMI. HDL3-C levels were significantly lower in patients with PMI than in those without (15.1 ± 3.0 mg/dL vs. 16.4 ± 2.9 mg/dL, p = 0.016) and had an independent and inverse association with PMI (odds ratio, 0.86; 95% confidence interval, 0.74-0.99; p = 0.038). When divided by the cut-off value of HDL3-C for PMI (14.3 mg/dL), the incidence of PMI was significantly higher in low HDL3-C patients than in high HDL3-C patients (51.2% vs. 30.2%, p = 0.020). HDL3-C was an independent inverse predictor of PMI in patients who underwent elective PCI.

    Owing to the increasing population of elderly patients, a large number of patients with degenerative spondylosis are currently being surgically treated. Although basic measures for decreasing postoperative surgical infections (PSIs) are considered, it still remains among the leading causes of morbidity and mortality. The aim of this retrospective analysis is to present possible causes leading to PSI in patients who underwent surgery for lumbar degenerative spondylosis and highlight how it can be avoided to decrease morbidity and mortality. The study included 540 patients who underwent posterior stabilization due to degenerative lumbar stenosis between January 2013 and January 2014. The data before and after surgery was retrieved from the hospital charts. Patients with degenerative lumbar stenosis who were operated upon in this study had >2 levels of laminectomy and facetectomy. For this reason, posterior stabilization was performed for all the patients included in this study. Determining the causes of postoperative infection (PI) following spinal surgeries performed with instrumentation is a struggle. Seventeen different parameters that may be related to PI were evaluated in this study. The presence of systemic diseases, unknown glove perforations, and perioperative blood transfusions were among the parameters that increased the prevalence of PI. Alternatively, prolene sutures, double-layered gloves, and the use of rifampicin Sv (RIS) decreased the incidence of PI. Although the presence of systemic diseases, unnoticed glove perforations, and perioperative blood transfusions increased PIs, prolene suture material, double-layered gloves, and the use of RIS decreased PIs.

    Full Text Available OBJECTIVE: Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal. METHODS: The records of patients who underwent Mohs micrographic surgery from October 2008 to November 2013 at the Dermatology Division of the Hospital of the Campinas University were assessed. The variables included were gender, age, anatomical location, histology, number of stages required and complications. RESULTS: Contingency tables were used to compare the number of stages with the histological diagnosis. The analysis showed that patients with superficial basal cell carcinoma were 9.03 times more likely to require more than one stage. A comparison between complications and histological diagnosis showed that patients with superficial basal cell carcinoma were 6.5 times more likely to experience complications. CONCLUSION: Although superficial basal cell carcinoma is typically thought to represent a less-aggressive variant of these tumors, its propensity for demonstrating “skip areas” and clinically indistinct borders make it a challenge to treat. Its particular nature may result in the higher number of surgery stages required, which may, as a consequence, result in more complications, including recurrence. Recurrence likely occurs due to the inadequate excision of the tumors despite their clear margins. Further research on this subtype of basal cell carcinoma is needed to optimize treatments and decrease morbidity.

    The relationship between diet and non-alcoholic fatty liver disease (NAFLD) in patients with gallstone disease and in those who have a high risk for NAFLD has not been investigated. This study was conducted to investigate the association between the risk of NAFLD and dietary pattern in patients who underwent cholecystectomy. Additionally, we assessed the association between erythrocyte fatty acid composition, a marker for diet, and the risk of NAFLD. Patients (n = 139) underwent liver ultrasonography to determine the presence of NAFLD before laparoscopic cholecystectomy, reported dietary intake using food frequency questionnaire, and were assessed for blood fatty acid composition. Fifty-eight patients were diagnosed with NAFLD. The risk of NAFLD was negatively associated with 2 dietary patterns: consuming whole grain and legumes and consuming fish, vegetables, and fruit. NAFLD was positively associated with the consumption of refined grain, meat, processed meat, and fried foods. Additionally, the risk of NAFLD was positively associated with erythrocyte levels of 16:0 and 18:2t, while it was negatively associated with 20:5n3, 22:5n3, and Omega-3 Index. The risk of NAFLD was negatively associated with a healthy dietary pattern of consuming whole grains, legumes, vegetables, fish, and fruit and with an erythrocyte level of n-3 polyunsaturated fatty acids rich in fish. © 2017 S.

    We developed a new risk factor profile for contrast-induced acute kidney injury (CI-AKI) under a new definition in patients who underwent an emergency percutaneous coronary intervention (PCI). Consecutive patients (n = 1061) who underwent an emergency PCI were divided into a derivation group (n = 761) and a validation group (n = 300). The rates of CI-AKI were 23.5% (definition 1: serum creatinine [SCr] increase ≥25% in 72 hours), 4.3% (definition 2: SCr increase ≥44.2 μmol/L in 72 hours), and 7.0% (definition 3: SCr increase ≥44.2 μmol/L in 7 days). Due to the high sensitivity of definition 1 and the high rate of missed cases for late diagnosis of CI-AKI under definition 2, definition 3 was used in the study. The risk factor profile included body surface area 15.00 × 10 9 /L ( P = .047), estimated glomerular filtration rate 133 μmol/L ( P = .007), intra-aortic balloon pump application ( P = .006), and diuretics administration ( P risk factor profile of CI-AKI under a new CI-AKI definition in emergency PCI patients is easily applicable with a useful predictive value.

    Previous studies have suggested that plasma fibrinogen contributes to tumor cell proliferation, progression and metastasis. The current study was performed to evaluate the prognostic relevance of preoperative plasma fibrinogen in breast cancer patients. Data of 2073 consecutive breast cancer patients, who underwent surgery between January 2002 and December 2008 at the Sun Yat-sen University Cancer Center, were retrospectively evaluated. Plasma fibrinogen levels were routinely measured before surgeries. Participants were grouped by the cutoff value estimated by the receiver operating characteristic (ROC) curve analysis. Overall survival (OS) was assessed using Kaplan-Meier analysis, and multivariate Cox proportional hazards regression model was performed to evaluate the independent prognostic value of plasma fibrinogen level. The optimal cutoff value of preoperative plasma fibrinogen was determined to be 2.83 g/L. The Kaplan-Meier analysis showed that patients with high fibrinogen levels had shorter OS than patients with low fibrinogen levels (p factor for OS in breast cancer patients (HR = 1.475, 95% confidence interval (CI): 1.177-1.848, p = 0.001). Subgroup analyses revealed that plasma fibrinogen level was an unfavorable prognostic parameter in stage II-III, Luminal subtypes and triple-negative breast cancer patients. Elevated preoperative plasma fibrinogen was independently associated with poor prognosis in breast cancer patients and may serve as a valuable parameter for risk assessment in breast cancer patients.

    Both high platelet reactivity (HPR) and Global Registry of Acute Coronary Events (GRACE) risk score have moderate predictive value for major adverse cardiovascular disease (CVD) events in patients with acute coronary syndrome (ACS) who underwent percutaneous coronary intervention (PCI), whereas the prognostic significance of GRACE risk score combined with platelet function testing remains unclear. A total of 596 patients with non-ST elevation ACS who underwent PCI were enrolled. The P2Y 12 reaction unit (PRU) value was measured by VerifyNow P2Y 12 assay and GRACE score was calculated by GRACE risk 2.0 calculator. Patients were stratified by a pre-specified cutoff value of PRU 230 and GRACE score 140 to assess 1-year risk of cardiovascular death, non-fatal myocardial infarction (MI), and stent thrombosis. Seventy-two (12.1%) patients developed CVD events during 1-year follow-up. Patients with CVD events had a higher PRU value (244.6 ± 50.9 vs. 203.7 ± 52.0, p risk independently. Compared to patients with normal platelet reactivity (NPR) and GRACE score risk (HR: 5.048; 95% CI: 2.268-11.237; p risk score yielded superior risk predictive capacity beyond GRACE score alone, which is shown by improved c-statistic value (0.871, p = 0.002) as well as net reclassification improvement (NRI 0.263, p risk of adverse CVD events. The combination of platelet function testing and GRACE score predicted 1-year CVD risk better.

    Nuclear factor of activated T-cells 5 (NFAT5) is known to be correlated with migration or invasion of tumor cells based on previous in vitro studies. The aim of this study was to analyze the relationship between NFAT5 expression and clinical prognosis in non-small cell lung cancer (NSCLC) patients who underwent surgical resection. A total of 92 NSCLC patients who underwent surgical resection were enrolled. The tissue microarray core was obtained from surgically resected tumor specimens. NFAT5 expression was evaluated by immunohistochemistry. Relationships of NFAT5 expression with disease recurrence, overall survival, and disease-free survival (DFS) were analyzed. The mean age of 92 patients was 63.7 y. The median follow-up duration was 63.3 mo. Fifty-one (55%) patients exhibited positive expression of NFAT5. Disease recurrence in the NFAT5-positive group was significantly (P = 0.022) higher than that in the NFAT5-negative group. NFAT5-positive expression (odds ratio: 2.632, 95% confidence interval: 1.071-6.465, P = 0.035) and pathologic N stage (N1-2 versus N0; odds ratio: 3.174, 95% confidence interval: 1.241-8.123, P = 0.016) were independent and significant risk factors for disease recurrence. DFS of the NFAT5-positive group was significantly worse than that of the NFAT5-negative group (89.7 versus 48.7 mo, P = 0.011). A multivariate analysis identified NFAT5 expression (P < 0.029) as a significant independent risk factor for DFS of patients with postoperative pathologic T and N stages (P < 0.001 and P = 0.017, respectively). NFAT5 expression is a useful prognostic biomarker for NSCLC patients who underwent surgical resection. Copyright © 2018 Elsevier Inc. All rights reserved.

    To evaluate the accuracy of MDCT in the preoperative definition of Peritoneal Cancer Index (PCI) in patients with advanced ovarian cancer who underwent a peritonectomy and hyperthermic intraperitoneal chemotherapy (HIPEC) after neoadjuvant chemotherapy to obtain a pre-surgery prognostic evaluation and a prediction of optimal cytoreduction surgery. Pre-HIPEC CT examinations of 43 patients with advanced ovarian cancer after neoadjuvant chemotherapy were analyzed by two radiologists. The PCI was scored according to the Sugarbaker classification, based on lesion size and distribution. The results were compared with macroscopic and histologic data after peritonectomy and HIPEC. To evaluate the accuracy of MDCT to detect and localize peritoneal carcinomatosis, both patient-level and regional-level analyses were conducted. A correlation between PCI CT and histologic values for each patient was searched according to the PCI grading. Considering the patient-level analysis, CT shows a sensitivity, specificity, PPV, NPV, and an accuracy in detecting the peritoneal carcinomatosis of 100 %, 40 %, 93 % 100 %, and 93 %, respectively. Considering the regional level analysis, a sensitivity, specificity, PPV, NPV, and diagnostic accuracy of 72 %, 80 %, 66 %, 84 %, and 77 %, respectively were obtained for the correlation between CT and histology. Our results encourage the use of MDCT as the only technique sufficient to select patients with peritoneal carcinomatosis for cytoreductive surgery and HIPEC on the condition that a CT examination will be performed using a dedicated protocol optimized to detect minimal peritoneal disease and CT images will be analyzed by an experienced reader.

    To classify patients with nonmetastatic advanced gastric cancer who underwent D2-gastrectomy into prognostic groups based on peritoneal and systemic recurrence risks. Between 2004 and 2007, 1,090 patients with T3-4 or N+ gastric cancer were identified from our registry. Recurrence rates were estimated using a competing-risk analysis. Different prognostic groups were defined using recursive partitioning analysis (RPA). Median follow-up was 7 years. In the RPA-model for peritoneal recurrence risk, the initial node was split by T stage, indicating that differences between patients with T1-3 and T4 cancer were the greatest. The 5-year peritoneal recurrence rates for patients with T4 (n = 627) and T1-3 (n = 463) disease were 34.3% and 9.1%, respectively. N stage and neural invasion had an additive impact on high-risk patients. The RPA model for systemic relapse incorporated N stage alone and gave two terminal nodes: N0-2 (n = 721) and N3 (n = 369). The 5-year cumulative incidences were 7.7% and 24.5%, respectively. We proposed risk stratification models of peritoneal and systemic recurrence in patients undergoing D2-gastrectomy. This classification could be used for stratification protocols in future studies evaluating adjuvant therapies such as preoperative chemoradiotherapy. J. Surg.

    Despite recent advances in the treatment of advanced gastric carcinomas, no satisfactory outcomes are available because of micrometastases and free-floating carcinoma cells already existing in the peritoneal cavity. From 1990, we started using intraperitoneal hyperthermo-chemo-perfusion (IHCP) to prevent and to treat peritoneal metastasis after surgical resection of stomach cancer. We analyzed 103 serosa-invasive gastric carcinoma patients who underwent surgical resection between 1990 and 1995. Fifty-two patients who received surgery plus IHCP were compared with 51 patients who underwent surgery only, as controls. IHCP was administered for 2 h with an automatic IHCP device (closed-circuit system) just after surgical resection, with the patient under hypothermic general anesthesia (32.4 degrees C-34.0 degrees C). As perfusate, we used 1.5% peritoneal dialysis solution mixed with 10 micrograms/ml of mitomycin-C (MMC), warmed at an inflow temperature of over 44 degrees C. The overall 5-year survival rate (5-YSR) of the 103 patients was 29.97%. The 5-YSR was higher in the IHCP group than in the control group, at 32.7% and 27.1%, respectively, but this difference was not significant. However, in the 65 serosa-invasive gastric carcinoma patients (excluding those in stage IV) the 5-YSR was significantly higher (P = 0.0379) in the IHCP group than in the control group, at 58.6% and 44.4%, respectively. On multivariate analysis of all 103 patients, depth of tumor invasion and lymph node metastasis were significant factors for survival, whereas significant factors on univariate analysis, such as combined operation, distant metastasis, and peritoneal metastasis, were not significant. The most common recurrence patterns were loco-regional in the IHCP group and peritoneal in the control group. Complete cytoreductive surgery plus IHCP is effective to prevent and to treat peritoneal metastasis, and it should lead to long-term survival for serosa-invasive gastric carcinoma patients

    Purpose There are many grey areas in the field of penile rehabilitation after radical prostatectomy (RP). The preservation of the full dimensions of the penis is an important consideration for improving patients' compliance for the treatment. We present the first case series of patients treated by laparoscopic extraperitoneal RP and simultaneous penile prosthesis implantation (PPI) in order to preserve the full length of the penis and to improve patients' satisfaction. Materials and Methods From June 2013 to June 2014, 10 patients underwent simultaneous PPI (with an AMS InhibiZone prosthesis) and RP. Patients were evaluated by means of urological visits, questionnaires, and objective measurements before surgery, at discharge from the hospital, on postoperative days 21 to 28, each 3 months for the first year, and each 6 months thereafter. The main outcome measures were biochemical recurrence-free rate, penile length, and quality of life. Results Ten patients (mean age of 61 years; completed the study follow-up period (median, 32.2 months). No difference was found between the time of surgery and the 2-year follow-up evaluation in terms of penile length. The pre-surgery 36-Item Short Form Health Survey (SF-36) median score was 97. Patients were satisfied with their penile implants, and couples' level of sexual satisfaction was rated median 8. The median postoperative SF-36 score was 99 at 3 months follow-up. Conclusions Laparoscopic extraperitoneal RP surgery with simultaneous PPI placement seems to be an interesting possibility to propose to motivated patients for preserving the length of the penis and improving their satisfaction.

    The goal in the treatment of developmental dysplasia of the hip (DDH) is to achieve a stable and concentric reduction and to create a congruent relationship between the femoral head and the acetabulum. This study discusses the causes of loss of reduction in DDH patients who had a concentrically reduced hip at the time of removal of the hip spica cast and cessation of brace use and who later appeared with hip redislocation after mobilisation and ambulation. In addition, the possible interventions in such cases are also discussed. A retrospective evaluation was made of 13 patients diagnosed with DDH who developed redislocation following primary surgery. 6 of them had undergone the 1st surgery in our department between 2008 and 2016 and 7 had udergone surgery in another centre. For comparison reasons a 2nd group was formed of 13 demographically and clinically matched patients who had no loss of reduction. The groups were compared in terms of acetabular index, pelvic length, pelvic width, abduction degree of plaster, ossifying nucleus diameter, acetabular depth, and acetabular volume parameters. The average age of the patients was 23 months at initial surgery and 29 months at the time of revision surgery. No significant difference was found between the groups in terms of acetabular inclination angle, ossifying nucleus diameter, pelvic size, pelvic width, centre edge angle, acetabular volume, and depth. Contracted inferomedial capsule was found in 1 patient who underwent revision surgery and intact transverse acetabular ligament was seen in 1 patient. The loss of reduction in the remaining 11 patients was associated with high total anteversion of the femoral head and acetabulum. Correction of increased combined anteversion by femoral osteotomy can create a safe zone in terms of redislocation and can significantly contribute to the stability provided by capsulorrhaphy and pelvic osteotomy.

    To determine the value of a raw data-based metal artifact reduction (SEMAR) algorithm for image quality improvement in abdominal CT for patients with small metal implants. Fifty-eight patients with small metal implants (3-15 mm in size) who underwent treatment for hepatocellular carcinoma were imaged with CT. CT data were reconstructed by filtered back projection with and without SEMAR algorithm in axial and coronal planes. To evaluate metal artefact reduction, mean CT number (HU and SD) and artefact index (AI) values within the liver were calculated. Two readers independently evaluated image quality of the liver and pancreas and visualization of vasculature using a 5-point visual score. HU and AI values and image quality on images with and without SEMAR were compared using the paired Student's t-test and Wilcoxon signed rank test. Interobserver agreement was evaluated using linear-weighted κ test. Mean HU and AI on images with SEMAR was significantly lower than those without SEMAR (P < 0.0001). Liver and pancreas image qualities and visualizations of vasculature were significantly improved on CT with SEMAR (P < 0.0001) with substantial or almost perfect agreement (0.62 ≤ κ ≤ 0.83). SEMAR can improve image quality in abdominal CT in patients with small metal implants by reducing metallic artefacts. (orig.)

    Analysis of associations between changes in neurotic personality profile and reductionof suicidal ideation (SI) - or lack of such reduction - defined as its elimination or reduction of its intensity in patients who underwent a course of intensive psychotherapy conducted in integrative approach with predominance of psychodynamic approach. Symptom Checklist KO"O", Neurotic Personality Questionnaire KON-2006 and Life Inventory completed by 461 women and 219 men treated due to neurotic, behavioral or personality disorders in a day hospital between 2005-2013. During the qualification for the therapy 134 women and 80 men reported SI, of whom 84.3% and 77.5% respectively improved. Patients who improved in terms of SI obtained significantly greater reduction of global neurotic personality disintegration (neuroticism) than others (ppsychotherapy as a treatment method that leads to comprehensive improvement encompassing reduction of neurotic personality disorders (neuroticism) and of majority of neurotic personality traits, as well as SI reduction. The revealed associations weigh in favor of hypothesis on neuroticism as SI predisposing factor in patients with neurotic, behavioral and personality disorders.

    To describe the long-term results, quality of life and chronic pain after chest wall fixation for traumatic rib fracture using a quality of life (QOL) score and a numeric pain score. Retrospective analysis of 10 consecutive patients who underwent surgery for rib fractures after trauma and reconstruction between October 2010 and March 2012. Chest rib fractures were fixed with titanium clips and bars or titanium plates and screws through a posterolateral thoracotomy. Pain was assessed with a numeric pain scale 0-10 and quality of life (QOL) with the EORTC questionnaire QLQ-C30. There were 5 males and 5 females. The median age was 58 years (range 21-80). There were no postoperative deaths. The only postoperative complication observed was a contralateral pleural effusion requiring drainage. Median length of stay of the drain and median length of hospital stay were 2 days (range 0-8) and 4 days (range 1-42 days), respectively. The average follow-up period of operatively managed patients was 14 months (range 8-23.5 months). Seven patients scored the pain as 0, one as 1 (mild), one as 4 (moderate) and one as 8 (severe). Only two patients are taking occasionally pain killers. Only one patient presents severe limitation in his life scoring his QOL as poor. Titanium devices (clips and bars; screws and plates) are effective and safe for repair of rib fractures and showed good long-term results in terms of pain and quality of life after the operation.

    Pinpointing the location of accessory conduction pathway (ACP) is of great importance in the surgical treatment for Wolff-Parkinson-White (WPW) syndrome. For this purpose, this study explored the usefulness of ECG-gated emission computed tomography (Gated-ECT) in 30 patients who preoperatively underwent Gated-ECT. The site of earliest contraction at level of atrioventicular valves, obtained on tomographic phase analysis, was compared with the site of earliest activation, obtained on epicardial mapping during surgery. The concordance rate of the two methods was 94 % (28/30). Among them, one patient was found to have the association of corrected transposition of great arteries on Gated-ECT. Gated-ECT was, however, of limited value in differentiating right posterior ACP from right postseptal ACP. The discordance between the sites of earliest contraction and activation, which was observed in the two others, was likely due to decreased wall motion resulting from myocardial disturbance. Gated-ECT may have a diagnostic potential for the location of ACP, especially in view of providing images that corresponded to the surgical anatomy. (Namekawa, K.).

    Objective: to assess in depth the effect of ventricular stimulation from the right ventricular outflow tract and the apex on mechanical ventricular synchrony. Materials And Methods: cohort analytical study. 20 patients with indication of definitive pacemaker indication underwent trans thoracic echocardiogram before and after pacemaker implant with electrode implantation in the right ventricular outflow tract and in the apex (10 patients in each group). There was no structural cardiopathy, ejection fraction was ? 50%, QRS and AV conduction were normal. Mechanical ventricular asynchrony (M mode and tissue doppler) and implant and device parameters were evaluated. Statistical Analysis: results are given as mean values, standard deviation or percentages.Continuous variables were compared using Chi-square test and ANOVA. A p <0.05 value was considered statistically significant. Results: in five patients (25%) a pre-implant ventricular asynchrony was found; in seven (70%) ventricular asynchrony post-implant in the right ventricle outflow tract and in 5 (50%) in the apex. Mean interventricular pot-implant delay was 21,6 ms in the right ventricular outflow tract and 11,5 ms in the apex (p = 0,8); mean septal to lateral wall delay was 73 ms in the right ventricular outflow tract and 26 ms in the apex (p = 0,8). QRS post-implant delay was 134 ms in the right ventricular outflow tract and 140 ms in the apex (p = 0,1). No differences between implant parameters and device programming were found. Conclusions: presence of ventricular asynchrony was evidenced in patients with normal QRS and structurally healthy heart. Ventricular stimulation with pacemaker from the apex or the right ventricular outflow tract suggests acute ventricular asynchrony at least in 60% of the cases, without statistically significant difference between both groups.

    Surgeries may trigger the stress response which leads to changes in blood glucose level, and studies suggest that different sedation and anesthesia methods have different effects on blood glucose level. The aim of this study was to investigate changes of blood glucose levels in diabetic patients and compare them in two sedation methods of propofol + fentanyl and midazolam + fentanyl. Totally, 80 diabetic candidates for cataract surgery who had all the inclusion criteria, underwent cataract surgery using two methods of propofol (1 mg/kg/h) + fentanyl (2 μg/kg) (Group P) and midazolam (0.03 mg/kg) + fentanyl (2 μg/kg) (Group M) for light sedation. In the end, 70 patients (Group P n = 35 and Group M n = 35) remained in the study. Patients' blood glucose levels, vital signs, and hemodynamic data were assessed 30 min prior to the surgery, each 15 min during surgery and at the end of surgery. Hemodynamic parameters did not have a statistically significant difference between the two groups mean blood glucose level in Group M was 149.15 mg/dl and in Group P was 149.2 mg/dl, and based on repeated measures analysis of variance test, significant differences were not observed between the two groups (P = 0.99). T-test showed no significant differences in the blood glucose level at any time of the study between the two groups. Light sedation methods of propofol + fentanyl and midazolam + fentanyl did not have any differences in alteration of blood glucose level.

    Objective To compare the effect of two different hand exercises on hand strength and vascular maturation in patients who underwent arteriovenous fistula surgery. Methods We recruited 18 patients who had chronic kidney disease and had undergone arteriovenous fistula surgery for hemodialysis. After the surgery, 10 subjects performed hand-squeezing exercise with GD Grip, and other 8 subjects used Soft Ball. The subjects continued the exercises for 4 weeks. The hand grip strength, pinch strength (tip, palmar and lateral pinch), and forearm circumference of the subjects were assessed before and after the hand-squeezing exercise. The cephalic vein size, blood flow velocity and volume were also measured by ultrasonography in the operated limb. Results All of the 3 types of pinch strengths, grip strength, and forearm circumference were significantly increased in the group using GD Grip. Cephalic vein size and blood flow volume were also significantly increased. However, blood flow velocity showed no difference after the exercise. The group using Soft Ball showed a significant increase in the tip and lateral pinch strength and forearm circumference. The cephalic vein size and blood flow volume were also significantly increased. On comparing the effect of the two different hand exercises, hand-squeezing exercise with GD Grip had a significantly better effect on the tip and palmar pinch strength than hand-squeezing exercise with Soft Ball. The effect on cephalic vein size was not significantly different between the two groups. Conclusion The results showed that hand squeezing exercise with GD Grip was more effective in increasing the tip and palmar pinch strength compared to hand squeezing exercise with soft ball.

    Transanal endoscopic microsurgery (TEMS) is emerging as an alternative treatment for rectal cancer Stage I. There remains a risk of local recurrence. The Aim of the study was to study the effect of biomarkers in local recurrence for Stage I rectal cancer following TEMS plus or minus radiotherapy. This is a case control study where we compared 10 early rectal cancers that had recurred, against 19 cases with no recurrence, total 29 patients (age=28.25-86.87, mean age=67.92 years, SD=14.91, Male, N=18, Female, N=11). All patients underwent TEMS for radiological Stage I rectal cancer (yT1N0M0 or yT2N0M0) established with combination of magnetic resonance imaging (MRI) and endorectal ultrasound. We prospectively collected all data on tumour histology, morphological features, as well as follow-up parameters. Molecular analysis was performed to identify their status on BRAF, KRAS, p16 O 6 -methylguanine-DNA methyltransferase (MGMT) and β-catenin. Out of 29 specimens analyzed, 19 were KRAS wild type (65.9%) and 10 mutant (34.5%). Recurrence of the tumour was noted in 10 cases (34.5%) from which 60% were pT1 (N=6) and 40% pT2 (N=4). There was a statistically significant association between KRAS mutant status and local recurrence (N=6, p=0.037). P16 expression greater than 5% (mean=10.8%, min=0, max=95) is linked with earlier recurrence within 11.70 months (N=7, p=0.004). Membranous β-catenin expression (N=12, 48%) was also related with KRAS mutant status (p=0.006) but not with survival (p>0.05). BRAF gene was found to be wild type in all cases tested (N=23). KRAS/p16/β-catenin could be used as a combined biomarker for prediction of local recurrence and stratification of the risk for further surgery.

    Full Text Available The soft and periodontal tissues surrounding dental implants are particularly susceptible to bacteria invasion and inflammatory reactions due to complex histological structures. This study was carried out to investigate the influence of a propolis-containing hygienic agent on selected oral health parameters, oral microflora, and the condition of periodontal health. Sixteen subjects who underwent an oral rehabilitation with dental implants were selected and randomly assigned into two groups, which received a newly formulated propolis-containing toothpaste (3% (CA or a negative control without an active ingredient (CC. Approximal plaque index (API, oral hygiene index (OHI, debris component, and sulcus bleeding index (SBI were assessed in three subsequent stages. During the first and last examinations, the swabs were employed for microbiological inoculation. Propolis-containing toothpaste was found to be distinctively effective in improving oral health and the occurrence of gingivitis triggered by dental plaque. The qualitative and quantitative changes in oral bacteria spectrum were observed. Antibacterial measures containing propolis might be used as a natural adjuvant to other active substances in individuals with a high risk of periodontal problems against pathogenic oral microflora.

    Full Text Available Background: Cardiovascular diseases are the main cause of 40% of deaths in Iran annually. Many patients undergoing coronary artery bypass graft surgery have previous cardiovascular risk factors which could be prevented. Objectives: The present study aimed to assess the prevalence of cardiovascular risk factors in the patients undergoing coronary artery bypass graft surgery. Materials and Methods: In this cross-sectional (descriptive – analytical study, a data collecting form was used. A total of 246 patients were selected from six hospitals of Shiraz using random stratification. Descriptive statistics were presented through figures and tables and t-test was used to analyze the continuous variables. All the statistical analyses were performed using the SPSS statistical software (version 15.0. Besides, P < 0.05 was considered as statistically significant. Results: Among the study patients, only 11.67% had no risk factors and 88.33% had one or more risk factors. The most common risk factors observed in the patients were hypertension, obesity and overweight, hyperlipidemia, and diabetes mellitus. The results showed a significant difference between males and females regarding the prevalence of hypertension (P = 0.001, diabetes (P = 0.028, hypercholesterolemia (P = 0.020, and cigarette smoking (P = 0.001. In addition, the patients' mean levels of cholesterol, LDL, triglyceride, and fasting blood sugar were higher than the acceptable level, while that of HDL was lower than the accepted level. Conclusions:: These patients are recommended to be trained regarding lifestyle changes. Also, prevention strategies can play an important role in reducing patient morbidity and mortality.

Methods Retrospective analysis of 86 patients with T1-2N0-1 OSCC who received surgery between January 2000 and December 2006. Fourteen patients (16.3% received postoperative radiotherapy (PORT. Patient characteristics, tumor characteristics, treatment modality, failure patterns, and survival rates were analyzed. Results The median follow-up was 45 months. The five-year overall survival (OS and disease-free survival (DFS rates were 80.8% and 80.2%, respectively. Higher tumor grade and invasion depth ≥ 0.5 cm were the significant prognostic factors affecting five-year OS and DFS (OS rate; 65% vs. 91%, p = 0.001 for grade; 66% vs. 92%, p = 0.01 for invasion depth: DFS rate; 69% vs. 88%, p = 0.005 for grade; 66% vs. 92%, p = 0.013 for invasion depth. In the risk group, there was no local failure in patients with postoperative radiotherapy. Conclusions In T1-2N0-1 OSCC, factors that affected prognosis after primary surgery were higher tumor grade and deep invasion depth over 0.5 cm. Postoperative radiotherapy should be considered in early oral tongue cancer patients with these high-risk pathologic features.

    To compare hemoglobin, ferritin, and vitamin B12 levels in patients undergoing upper GI endoscopy according to their Helicobacter pylori status. All patients undergoing upper GI Endoscopy were selected, while patients of active peptic ulcers, malignancy, varices, malabsorption and recent blood donation were excluded. Blood samples for CBC, serum ferritin and vitamin B12 were collected and H.pylori status was ascertained by urease test on gastric biopsy. Differences in mean values of age, ferritin, hemoglobin, MCV and vitamin B12 were done by students t-test. Significant confounding factors were identified on multivariate analysis and were further analyzed by univariate analysis. Two hundred and eighty-five subjects were studied, including 171 males and 114 females. H-pylori was positive in 214 (75.1%) patients. Significantly low levels of hemoglobin (p =0.0), ferritin (p = 0.0) and vitamin B12 (p = 0.0) were found in patients with H-pylori infection. Gender, menopause, contraception and history of peptic ulcer disease were identified as significant confounders. Significantly low levels of hemoglobin, ferritin and vitamin B12 were found in patients with H-pylori infection. (author)

To evaluate the features of blood flow at the level of the microcirculatory bed of the skin (MC in the conditions of comorbid pathology and increased coagulation potential of the blood in patients with atrial fibrillation (AF.Material and methods. The following groups were formed by random sampling: the main (group 1, n=50 group of patients with paroxysmal or persistent form of AF, after cardioembolic stroke. The comparison group (group 2, n=50 consisted of patients with paroxysmal or persistent AF without a history of stroke. The control group (group 3, n=50 – patients comparable on the basic parameters of patients from groups 1 and 2, but without AF and stroke. The plasma levels of von Willebrand factor (vWF, tissue plasminogen activator inhibitor-1 (PAI-1, antithrombin III (AT III and plasminogen were determined. All MC parameters were studied with a single-channel laser cutaneous blood flow analyzer for the general practitioner "LAKK-OP" in the area of the finger pad during the period, when a patient had sinus rhythm.Results. The obtained results indicate the disorders of microcirculation processes in patients with AF after stroke, which are expressed in decrease in tissue perfusion, specific oxygen consumption (I and relative perfusion of the microcirculation saturation (Sm. Significantly higher levels of vWF, PAI-1 and low levels of AT III were observed in patients with AF and stroke than these in the group of patients with AF. It was found that Sm in patients of the group 1 statistically significantly correlated with vWF (r=-0.61; p=0.0032, plasminogen (r=0.45; p=0.0084, PAI-1 (r=-0.43; p=0.0027 and AT III (r=0.49; p=0.0065.Conclusion. The revealed disorders of microcirculatory processes are significantly related with the disturbances of the hemostatic function of the endothelium. From the pathophysiological point of view, that is one of the negative risk factors of the development of recurrent thrombus formation.

    Full Text Available Abstract:One of the variants for the surgical treatment of patients with bilobal liver metastases is to perform two-stage anatomic resections. Thus, at least in a quarter of the patients it is impossible to perform the second stage of intervention because of absence of hypertrophy of the remaining liver parenchyma or progression of disease during standby. The most modern and promising way of overcoming this obstacle is to perform the so-called ALPPS (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy or «in situ slit» liver resections. In this article we present a clinical case of performing a two-stage hepatectomy by type ALPPS in patients with metastatic colorectal cancer liver, who previously undergone the anatomic bisegmentectomy SVI-SVII. The present observation is the first in the available literature, evidence of justification perform repeated liver resections in patients with metastatic colorectal cancer and demonstrates the possibility of ALPPS techniques when performing extensive anatomical liver resections in patients who have undergone previous removal of the parenchyma of the right lobe.

    Low-density lipoprotein (LDL) oxidation is an important event in atherosclerosis development. The relationship between oxidized LDL (oxLDL) autoantibodies and coronary artery disease (CAD) remains controversial. IgM and IgG autoantibodies to oxLDL were measured in twenty patients undergoing clinically indicated coronary angiography, and in ten young healthy volunteers from the Center of Molecular Immunology. The levels of IgM autoantibodies to oxLDL did not differ between no CAD patients and healthy subjects, but the levels of IgM autoantibodies to oxLDL of these two groups were higher compared with the one of CAD patient group. Our results, although preliminary, supports the hypothesis that this kind of Abs might be inversely associated with the presence of atherosclerosis

    Conclusions:: There is a high possibility that these adverse reactions were caused by pseudoallergy to drug. Even by allergic reactions, it was assumed that 80% of them might be caused by antiseptic agents such as paraben. In addition, it was suggested that ALAs, especially lidocaine hydrochloride preparations have high antigenicity (sensitizing property. Furthermore, it was considered that patients with past history of drug or food allergies have a high potential for manifestation of the reactions.

Our study was designed to assess whether AGR is associated with the prognosis of gastric cancer patients. Patients and methods: A total of 507 gastric cancer patients between 2005 and 2012 were included. The AGR was defined as the ratio of serum albumin to nonalbumin and calculated by the equation: albumin/(total protein - albumin. Furthermore, AGR was divided into two groups (low and high using the X-tile software. Survival analysis stratified by AGR groups was performed. Results: The mean survival time for each group was 36.62 months (95% CI: 33.92–39.32 for the low AGR group and 48.95 months (95% CI: 41.93–55.96, P=0.003 for the high AGR group. Patients in the high group (AGR ≥1.93 had a significantly lower 5-year mortality in comparison with the low group (AGR <1.93 (52.4% vs 78.5%, P=0.003. The high AGR group showed obviously better overall survival than the low AGR group according to Kaplan–Meier curves (P=0.003. Multivariate analysis showed that AGR was an independent predictive factor of prognosis in gastric patients. Conclusion: Pretreatment AGR is a significant and independent predictive factor of prognosis. Keywords: gastric cancer, survival, inflammation, albumin–globulin ratio

    Sensitivity, specificity and predictivity were determined for ultrasonographic findings of the endometrial cavity with the findings in the outpatient surgery program of the Servicio de Ginecologia of Hospital Mexico in 2010. The data were collected retrospectively by taking randomly a sample of the total of 147 patients with hysteroscopy. Data from selected clinical records are taken to perform statistical analysis using histories for the most frequent findings and to measure the diagnostic accuracy of both transvaginal econography and hysteroscopy. Necmar's 2x2 table is used, for to calculate the values of sensitivity, specificity, positive and negative and to obtain the comparative results. The ultrasonographic findings were: endometrial polipo 60%, endometrial thickening 20% and submucous myoma 11%. The postoperative diagnoses were: endometrial polyposis 65%, endometrial cavity without lesions 11%, submucous myoma 9%, endometrial hyperplasia 7% and endometrial atrophy 3%. Transvaginal ultrasound is proved to be an acceptable diagnostic method for endometrial polipo because it had a positive predictive value of 79%. In the submucous myoma, are found values of specificity and a very high negative predictive value, which indicates that ultrasound is actually able to rule out the presence of this pathology [es

    Full Text Available Introduction: There is a steady increase in the number of elderly patients with severe cardiovascular diseases who require a surgical procedure to recover some quality of life that allows them a socially meaningful existence, despite the risks. Objectives: To analyze the behavior of elderly patients who underwent cardiac surgery with cardiopulmonary bypass. Method: A descriptive, retrospective, cross-sectional study was conducted with patients over 65 years of age who underwent surgery at the Cardiocentro Ernesto Che Guevara, in Santa Clara, from January 2013 to March 2014. Results: In the study, 73.1% of patients were men; and there was a predominance of subjects between 65 and 70 years of age, accounting for 67.3%. Coronary artery bypass graft was the most prevalent type of surgery and had the longest cardiopulmonary bypass times. Hypertension was present in 98.1% of patients. The most frequent postoperative complications were renal dysfunction and severe low cardiac output, with 44.2% and 34.6% respectively. Conclusions: There was a predominance of men, the age group of 65 to 70 years, hypertension, and patients who underwent coronary artery bypass graft with prolonged cardiopulmonary bypass. Renal dysfunction was the most frequent complication.

    High-resolution manometry (HRM) has been applied to assess esophageal motility disorders. However, the frequency and types of motility disorders in patients with dysphagia, which are frequently seen in clinical practice, are not clear. We evaluated latent esophageal motility disorders associated with dysphagia. The study included patients without erosive esophageal mucosal damage and with dysphagia symptoms refractory to at least 8 weeks of standard-dose proton pump inhibitors. After enrolment, HRM was used to evaluate for esophageal motility disorder based on the Chicago classification. Esophageal motility disorder was found in 58 of 100 patients and was classified based on the causes: achalasia (13%), esophagogastric junction outflow obstruction (16%), distal esophageal spasms (3%), weak peristalsis (14%), frequently failed peristalsis (5%), and hypertensive peristalsis (7%). Primary esophageal motility disorder was found in approximately 50% of cases in dysphagia patients. Therefore, esophageal motility disorder is not an uncommon condition and should be sought for in order to elucidate precisely the cause of dysphagia. © 2017 S. Karger AG, Basel.

    The aim of this study was to determine the prevalence of catatonic symptoms, as per the Bush Francis Catatonia Rating Scale (BFCRS), in patients with delirium and to evaluate the prevalence of catatonia as defined by the Bush Francis Catatonia Screening Instrument and DSM-5 criteria in patients with delirium. Two hundred five consecutive subjects with delirium were assessed on the Delirium Rating Scale-Revised 98 version, the amended Delirium Motor Symptom Scale and the BFCRS. On the BFCRS, two-fifths (n = 80; 39%) of the study participants had two or more catatonic symptoms. When the diagnosis of catatonic syndrome was considered, 32% and 12.7% were observed to have catatonia as per the Bush Francis Catatonia Screening Instrument and proposed DSM-5 criteria, respectively. Delirium with catatonic syndrome was more common in women and in those who had onset of delirium prior to hospitalization. Amongst the delirium subtypes, hypoactive delirium was more commonly associated with catatonic syndrome. The present study suggests that a substantial number of patients with delirium have catatonic symptoms and a significant proportion have catatonic syndrome. This high prevalence makes the concurrent diagnosis of delirium and catatonia plausible. The association of catatonia with a specific motor subtype of delirium could encourage the expansion or even modification of the existing subtypes of delirium. © 2014 The Authors.

    2014-01-01

    Background Several researchers imply that both work-related and non-work-related stress exposure are likely to contribute to stress-related mental illness. Yet empirical studies investigating both domains seem to be limited, particularly in a clinical population. The purpose of this study was to a) explore which stressors (non-work and work-related) are reported as important for the onset of illness by patients seeking medical care for stress-related exhaustion and b) explore the prevalence of each stressor and examine whether the pattern differs between men and women. Methods This is an exploratory mixed method study, comprising patients at a specialist outpatient stress clinic. Information from medical records of 20 patients was initially used in a first qualitative step to construct the instrument, using a combination of a conventional content analysis and a directed content analysis. In the second phase patient records from 50 men and 50 women were selected and coded in accordance with the coding instrument. Frequency statistics were calculated for all stressors. Results A total of 24 categories of stressors (11 related to work and 13 related to private life) were identified in the first qualitative step. A median of four stressors, usually both work and non-work-related was reported by the patients. The most common stressors were 1) quantitative demands at work, 2) private relational conflicts and 3) emotional demands at work. Conclusions Work demands are, by far, the most prevalent stressor, followed by relational problems in private life. The pattern was similar for women and men, with a slight difference in the distribution between work and non-work stressors. Men and women also show similar patterns when comparing the occurrence of each stressor. Slight differences were seen, in particular with regard to managerial responsibility that was reported by 6% of the women compared to 36% of the men. One important practical implication of this study is that

    To clarify the significant clinicopathological and postdosimetric parameters to predict PSA bounce in patients who underwent low-dose-rate brachytherapy (LDR-brachytherapy) for prostate cancer. We studied 200 consecutive patients who received LDR-brachytherapy between July 2004 and November 2008. Of them, 137 patients did not receive neoadjuvant or adjuvant androgen deprivation therapy. One hundred and forty-two patients were treated with LDR-brachytherapy alone, and 58 were treated with LDR-brachytherapy in combination with external beam radiation therapy. The cut-off value of PSA bounce was 0.1 ng/mL. The incidence, time, height, and duration of PSA bounce were investigated. Clinicopathological and postdosimetric parameters were evaluated to elucidate independent factors to predict PSA bounce in hormone-naïve patients who underwent LDR-brachytherapy alone. Fifty patients (25%) showed PSA bounce and 10 patients (5%) showed PSA failure. The median time, height, and duration of PSA bounce were 17 months, 0.29 ng/mL, and 7.0 months, respectively. In 103 hormone-naïve patients treated with LDR-brachytherapy alone, and univariate Cox proportional regression hazard model indicated that age and minimal percentage of the dose received by 30% and 90% of the urethra were independent predictors of PSA bounce. With a multivariate Cox proportional regression hazard model, minimal percentage of the dose received by 90% of the urethra was the most significant parameter of PSA bounce. Minimal percentage of the dose received by 90% of the urethra was the most significant predictor of PSA bounce in hormone-naïve patients treated with LDR-brachytherapy alone.

    Multiple sclerosis (MS) is a chronic multifocal CNS disorder which can affect higher order cognitive processes. Whereas cognitive disturbances in MS are increasingly better characterised, emotional facial expression (EFE) has rarely been tested, despite its importance for adequate social behaviour. We tested 20 patients with a clinically isolated syndrome suggestive of MS (CIS) or MS and 23 healthy controls (HC) for the ability to differ between emotional facial stimuli, controlling for the influence of depressive mood (ADS-L). We screened for cognitive dysfunction using The Faces Symbol Test (FST). The patients demonstrated significant decreased reaction-times regarding emotion recognition tests compared to HC. However, the results also suggested worse cognitive abilities in the patients. Emotional and cognitive test results were correlated. This exploratory pilot study suggests that emotion recognition deficits might be prevalent in MS. However, future studies will be needed to overcome the limitations of this study.

    This study aimed to evaluate the efficacy of low-level laser therapy (LLLT) and light-emitting diodes (LEDs) for reducing pain in hyperglycemic and normoglycemic patients who underwent coronary artery bypass surgery with internal mammary artery grafts. This study was conducted on 120 volunteers who underwent elective coronary artery bypass graft (CABG) surgery. The volunteers were randomly allocated to four different groups of equal size (n = 30): control, placebo, LLLT [λ = 640 nm and spatial average energy fluence (SAEF) = 1.06 J/cm(2)], and LED (λ = 660 ± 20 nm and SAEF = 0.24 J/cm(2)). Participants were also divided into hyperglycemic and normoglycemic subgroups, according to their fasting blood glucose test result before surgery. The outcome assessed was pain during coughing by a visual analog scale (VAS) and the McGill Pain Questionnaire. The patients were followed for 1 month after the surgery. The LLLT and LED groups showed a greater decrease in pain, with similar results, as indicated by both the VAS and the McGill questionnaire (p ≤ 0.05), on the 6th and 8th postoperative day compared with the placebo and control groups. The outcomes were also similar between hyperglycemic and normoglycemic patients. One month after the surgery, almost no individual reported pain during coughing. LLLT and LED had similar analgesic effects in hyperglycemic and normoglycemic patients, better than placebo and control groups.

Patient satisfaction data were collected using the MedRisk Instrument for Measuring Patient Satisfaction with Physical Therapy Care (MRPS) from a total of 1666 patients who were attending clinics for physiotherapy treatment of a musculoskeletal condition. Exploratory factor analysis was conducted to identify factors determining patient satisfaction in each cohort. A four-factor solution for the MRPS was found for the Australian and Korean data sets, explaining 61 and 55% of the variance respectively. Communication and respect, convenience and quality time and person-focused care were factors common to both countries. One factor unique to Korea was courtesy and propriety. For both cultures, global patient satisfaction was significantly but weakly correlated with the outcome of treatment. The interpersonal aspect of care, namely effective communication and respect from the therapist, appears to be the predominant and universal factor that influences patient satisfaction with physiotherapy care, although other culturally specific factors were identified. Physiotherapists can maximize patient satisfaction with care by addressing those features that uniquely contribute to patient satisfaction in the cultural context in which they are working.

    Patients with end-stage cancer and advanced chronic bowel disease are often malnourished, which has a negative effect on patients' outcome, well-being, and activity. It is inconclusive whether these patients benefit from home parenteral nutrition. This prospective exploratory study investigates its influence on nutrition state, muscle strength, mobility, and quality of life. Patients ≥18 years old with an indication for home parenteral nutrition were included and followed for 2-24 months. Nutrition parameters, activity, and quality of life were assessed. Forty-eight patients participated (mean age 11.5 years), and 85% were severely malnourished (subjective global assessment score, class C). Four weeks after parenteral nutrition, patients with tumors demonstrated a deterioration in phase angle (from 3.9 to 3.4) and extracellular mass:body cell mass ratio (from 1.6 to 2.1), while patients with bowel disease improved (from 3.4 to 4.0 and 2.1 to 1.6, respectively); grip strength remained constant in both groups (difference: 1.11 and -2.11, respectively). Activity improved in patients with bowel disease but stayed the same in the tumor group (P = .02 and P = .33, respectively). When the groups were pooled, emotional and social functioning domain scores (P parenteral nutrition. Both groups seem to benefit from home parenteral nutrition without harmful side effects. If the indication is determined early, the patients' disease course could perhaps be improved. © 2016 American Society for Parenteral and Enteral Nutrition.

  14. Assessing physician/patient relationships in the presence of HIV/AIDS: an exploratory study.

    The following study investigates the nature of the relationship between physicians and HIV/AIDS patients within the context of the rapidly evolving services/relationship marketing literatures. The emerging evidence suggests that service providers generally play a critical role in the development of positive consumer attitudes and behaviors, and that relationship marketing practices can contribute to the delivery of health services. However, to date, there appears little evidence supporting the efficacy of employing relationship marketing practices in relation to a target market of HIV/AIDS patients. This exploratory study contributes to the body of knowledge by more closely investigating the nature of the patient-physician relationship relative to HIV/AIDS patients' attitudes, marketing-related behaviors, and overall quality-of-life/life satisfaction judgments. The results of this study first suggest that HIV/AIDS patients use the expectancy disconfirmation model when evaluating the performance of their physician. A reliance on expectancy disconfirmation suggests the likely prevalent role of service quality perceptions and satisfaction judgments in evaluating their relationship with their physician. Second, the results appear to support the conclusion that the patient's evaluation of their physician relationship and subsequent behaviors (e.g., word-of-mouth) are directly related to the patient's general perception of received health services. Thus, the patient/physician relationship may play a particularly powerful role in determining patient (marketing related) outcomes relative to other health service settings. Third, a direct influence is supported between negative affective reactions by patients and subsequent outcome behaviors. This finding lends support for the potential efficacy of service recovery efforts when rendering treatment to HIV/AIDS patients. Finally, evidence is presented demonstrating the effect of positive perceptions of the patient

    Anti-T lymphocyte globulin Fresenius (rATG-F; ATG-Fresenius) and antithymocyte globulin (thymoglobulin), which are included in transplant protocols, are used to reduce the risk of chronic graft-versus-host disease (cGVHD) or suppress allograft rejection. Available clinical studies have been conducted in heterogenous patient populations and with different administration protocols including stem cell sources. Additionally, the pharmacokinetics of ATG is variable, and the clinically effective dose of rATG-F, in particular, is not exactly known. The aim of the study was to investigate the clinical outcomes of acute myeloid leukemia (AML) patients who underwent hemopoietic peripheral stem cell transplantation from full-matched sibling donors and given two different doses of r-ATG-F. This was a single-center, retrospective chart review conducted between July 2005 and July 2016. Sixty-nine consecutive AML patients who underwent transplant with fludarabine- and busulfan-based conditioning were included in the study. Patients in Group 1 received 15 mg/kg body weight rATG-F to 2013 (n = 46), and Group 2 received 30 mg/kg of rATG-F dose begining in 2013 to reduce to cGVHD (n = 23). Cyclosporine and methotrexate were used to treat acute GVHD (aGVHD) prophylaxis. Outcome parameters were compared between the groups. Although the recommended dose r-ATG-F had led to a decrease in the cumulative incidence of cGVHD (27 [58.7%] vs. 8 [34.8%]; p = .03), it also increased the infection rate at 1 year (3 [6.5%] vs. 4 [17.4%]; p = .02). The two groups were similar in terms of engraftment time, aGVHD, relapse, nonrelapse mortality, and rATG-F-related toxicity. A Cox regression model revealed that aGVHD III-IV was associated with increased nonrelapse mortality at 1 year (hazard ratio = 18.2; 95% confidence interval, 1.667-199.255; p = <.02). No patients developed rATG-F-related severe adverse events (Common Terminology Criteria grade 4 or 5). Dose difference of

    Hematopoietic stem cell transplantation is a common and preferred treatment of lymphomas in many centers. Our goal was to determine the association between pretransplant iron overload and survival in patients who underwent autologous hematopoietic stem cell transplantation (autoHSCT). A total of 165 patients with lymphoma, who underwent autoHSCT between the years of 2007 and 2014, were included in this study. Ferritin levels were used to determine iron status; the cut-off value was 500 ng/mL. The relationship between iron overload and survival was assessed by statistical analysis. The median ferritin level in the normal ferritin (ferritin < 500) group was 118 ng/mL (range, 9-494 ng/mL) and in the high-ferritin group (ferritin ≥ 500), it was 908 ng/mL (range, 503-4549 ng/mL). A total of 64 (38.8%) patients died during follow-up. Of these patients that died, 52 (81.25%) were in the high-ferritin group, and 12 (18.75%) were in the normal ferritin group (P ≤ .001). Twelve (14.1%) of 85 patients died in the normal ferritin group, and 52 (65.0%) of 80 patients died in the high-ferritin group. The overall mortality was significantly higher in the high-ferritin group (P < .001). The median overall survival was 42 months (range, 25-56 months) in the normal-ferritin group and20 months (range, 5-46) in the high-ferritin group. The difference between the groups was statistically significant (P < .001). The median disease-free survival was 39 months (range, 16-56) in the normal ferritin group and 10 months (range, 3-29) in the high-ferritin group. The difference between the groups was statistically significant (P < .001). Elevated serum ferritin levels might predict poorer survival in autoHSCT recipients. Copyright © 2016 Elsevier Inc.

    To identify the effects of a smart program for the patients who underwent percutaneous coronary intervention (SP-PCI) on coronary disease-related knowledge, health behaviors, and quality of life. A nonequivalent control group with a non-synchronized design was utilized and 48 participants (experimental=22, control=26) were recruited from a university hospital in Gyeongsang area from May to December, 2016. The 12-week SP-PCI consisted of self-study of health information using smart phone applications (1/week), walking exercise (>5/week) using smart band, feedback using Kakao talk (2/week), and telephone counseling (1/week). Patients in the control group received usual care from their primary health care providers and a brief health education with basic self-management brochure after the PCI. Data were analyzed using the SPSS 21.0 program through descriptive statistics, χ² test, and t-test. After the 12-week SP-PCI, the experimental group showed higher levels of coronary disease-related knowledge (t=2.43, p=.019), heart-related health behaviors (t=5.96, pPCI provided easy access and cost-effective intervention for patients after PCI and improved their knowledge of the disease, performance of health behaviors, and quality of life. Further study with a wider population is needed to evaluate the effects of SP-PCI on disease recurrence and quality of life for patients after PCI. © 2017 Korean Society of Nursing Science

    In patients with cancer, weight loss can be related to simple starvation, disturbed metabolism, or both. In patients with head and neck cancer (HNC), weight loss often is attributed to simple starvation because the obvious oral symptoms are known to hinder dietary intake. In this population, cachexia remains a relatively unexplored phenomenon. The aim of this study was to explore the prevalence of cachexia and precachexia in patients with newly diagnosed HNC. Fifty-nine patients with newly diagnosed HNC were asked to participate in the prospective cohort study, from which only baseline data were used in the analyses. Measurements were performed 1 wk before cancer treatment, that is, cachexia status by Fearon's cancer-specific framework, dietary intake, muscle mass, muscle strength, and biochemical markers (C-reactive protein, albumin, hemoglobin, interleukin-1β, interleukin-6, and tumor necrosis factor-α) were assessed. Data of 26 patients were included in the analyses (59% participation rate). Forty-two percent of the patients (n = 12) were classified as cachectic and 15% (n = 4) as precachectic. Muscle mass depletion was significantly more frequent in cachectic patients (67%) than in noncachectic patients (14%; P = 0.014). No differences in inflammatory markers were observed between cachectic and noncachectic patients. This exploratory study suggested a high prevalence of cachexia (42%) in patients with newly diagnosed HNC. Although a large study is needed to further elucidate the role of cachexia in patients with HNC, the data presented here suggest that cachexia is a common problem in this patient population, which has therapeutic and prognostic implications.

    We measured the serum concentration of a panel of inflammatory cytokines and evaluated their association with circulating proangiogenic biomarkers and with outcome in patients with pancreatic ductal adenocarcinoma (PDAC). We collected serum samples from 36 patients with PDAC, 9 patients with chronic pancreatitis, and 22 healthy volunteers as a control. Inflammatory cytokines and proangiogenic biomarkers were measured using the multianalyte xMAP array and carcinoembryonic antigen (CEA) and carbohydrate 19-9 by immunoassay. Patients with PDAC had higher circulating levels of interleukin 6 (IL-6) than those of patients with pancreatitis or healthy individuals and higher levels of IL-10 and tumor necrosis factor α (TNF-α) compared with those of healthy individuals. In patients with PDAC, circulating IL-6, TNF-α, IL-1β, and IL-10 correlated with serum concentrations of vascular endothelial growth factor and basic fibroblast growth factor; circulating IL-6, IL-1β, and TNF-α correlated with carbohydrate 19-9; and IL-8, IL-10, and TNF-α correlated with CEA levels. Circulating IL-8, TNF-α, and CEA; tumor stage; and lymph node metastases were associated with a poor outcome. The results of this exploratory study indicate that inflammatory cytokines should be pursued as potential prognostic biomarkers as well as targets for therapy in larger studies in PDAC.

    Full Text Available Abstract Background Surgery after (chemoradiation (RCTX/RTX is felt to be plagued with a high incidence of wound healing complications reported to be as high as 70%. The additional use of vascularized flaps may help to decrease this high rate of complications. Therefore, we examined within a retrospective single-institutional study the peri--and postoperative complications in patients who underwent surgery for salvage, palliation or functional rehabilitation after (chemoradiation with regional and free flaps. As a second study end point the Karnofsky performance status (KPS was determined preoperatively and 3 months postoperatively to assess the impact of such extensive procedures on the overall performance status of this heavily pretreated patient population. Findings 21 patients were treated between 2005 and 2010 in a single institution (17 male, 4 female for salvage (10/21, palliation (4/21, or functional rehabilitation (7/21. Overall 23 flaps were performed of which 8 were free flaps. Major recipient site complications were observed in only 4 pts. (19% (1 postoperative haemorrhage, 1 partial flap loss, 2 fistulas and major donor site complications in 1 pt (wound dehiscence. Also 2 minor donor site complications were observed. The overall complication rate was 33%. There was no free flap loss. Assessment of pre- and postoperative KPS revealed improvement in 13 out of 21 patients (62%. A decline of KPS was noted in only one patient. Conclusions We conclude that within this (chemoradiated patient population surgical interventions for salvage, palliation or improve function can be safely performed once vascularised grafts are used.

    Analysis of associations between changes in the intensity of neurotic symptoms and reduction of suicidal ideation (SI) or lack of SI reduction, in patients who underwent a course of intensive psychotherapy conducted in integrative approach with predominance of psychodynamic approach in a day hospital. Symptom Checklist KO"O" and Life Inventory completed by 461 women and 219 men treated in the psychotherapeutic day hospital due to neurotic, behavioral or personality disorders between 2005-2013. During the qualification for the therapy 134 women and 80 men reported SI, of whom 84.3% and 77.5% respectively improved. The reduction of neurotic symptoms intensity was greater in patients of both genders who improved in terms of SI than in those who did not. This referred to global intensity of neurotic symptoms (OWK coefficient) in both genders (ppsychotherapy as a treatment method that leads to improvement in terms of both SI and neurotic symptoms. This suggests that the applied therapy may be effective in preventing suicidality in this group of patients. The observed associations also point in favor of hypothesis on similarities in etiopathogenesis of and partly identical personality-related factors predisposing to SI and neurotic disorders.

    Generalist physicians must often counsel patients or their families about the right time to die, but feel ill-prepared to do so. Patient beliefs may help guide the discussions. Because little prior research addresses such beliefs, we investigated them in this exploratory, hypothesis-generating study. Anticipating culture as a key influence, we interviewed 26 Mexican Americans (MAs), 18 Euro-Americans (EAs), and 14 African Americans (AAs) and content-analyzed their responses. Nearly all subjects regardless of ethnic group or gender said God determines (at least partially) a patient's right time to die, and serious disease signals it. Yet subjects differed by ethnic group over other signals for that time. Patient suffering and dependence on "artificial" life support signaled it for the MAs; patient acceptance of death signaled it for the EAs; and patient suffering and family presence at or before the death signaled it for the AAs. Subjects also differed by gender over other beliefs. In all ethnic groups more men than women said the time of death is unpredictable; but more women than men said the time of death is preset, and family suffering signals it. Furthermore, most MA women--but few others--explicitly declared that family have an important say in determining a patient's right time to die. No confounding occurred by religion. Americans may share some beliefs about the right time to die but differ by ethnic group or gender over other beliefs about that time. Quality end-of-life care requires accommodating such differences whenever reasonable.

    To compare the diagnostic accuracy of ultrasonography (US), F18-fluorodeoxyglucose positron emission tomography/CT (PET/CT), contrast enhanced CT (CECT), serum anti-thyroid antibody for detecting Hashimoto's thyroiditis in thyroid cancer patients who underwent neck surgery. A total of 150 patients with suspicious for thyroid cancer, who had previously undergone US guided needle aspiration of thyroid, were evaluated with the use of US, PET/CT, CECT and serum anti-thyroid antibody. The four studies were performed within two months before neck surgery. Hashimoto's thyroiditis was confirmed by histopathological results. The diagnostic accuracy of US, PET/CT, CECT and serum anti-thyroid antibody were calculated statistically. Hashimoto's thyroiditis was diagnosed in 51 out of the 150 patients, following neck surgery. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of US were 76.5%, 92.9%, 84.8%, 88.5%, and 87.3%, respectively. The corresponding values of PET/CT were 37.3%, 96.0%, 82.6%, 74.8%, and 76.0%, and CECT were 62.7%, 89.9%, 76.2%, 82.4%, and 80.7%, and serum anti-thyroid antibody level were 90.2%, 93.9%, 88.5%, 94.9%, and 92.7%, respectively. McNemar test revealed significant difference among PET/CT and others, but no significant differences among US, CECT and serum anti-thyroid antibody. Overall, serum anti-thyroid antibody showed most accurate diagnostic performance. In detecting Hashimoto's thyroiditis, serum anti-thyroid antibody showed higher diagnostic accuracy than others. US also showed relatively high diagnostic accuracy.

    Factor analytic studies of delirium symptoms among patients referred through consultation-liaison psychiatric services are rare. We examined the factor structure of delirium symptoms in referred patients and determined whether combining items from several delirium rating scales influenced the factor structure of delirium symptoms. Eighty-six patients with delirium (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision) referred though the consultation-liaison services were assessed with structured rating scales. Nineteen symptom items extracted from the Delirium Rating Scale-Revised-98 (DRS-R-98), the Memorial Delirium Assessment Scale and the Confusional State Evaluation Scale were subjected to an exploratory (principal component) factor analysis. A second such analysis was conducted on 15 items of the DRS-R-98 for comparison. Compared with prior studies, patients were younger and the majority had hyperactive delirium. Principal components analysis identified two factors: (1) a "cognitive" factor comprising of disturbances in language, thought processes, orientation, attention, short- and long-term memory, visuospatial ability, consciousness (awareness) and perseveration accounted for 28.9% of the variance and (2) a "behavioral" factor consisting of sleep-wake cycle disturbances, delusions, perceptual disturbances, motor agitation, affect-lability, distractibility, irritability and temporal onset accounted for 18.9% of the variance. An identical factor structure was obtained with the DRS-R-98 items. Similar to previous factor analytic studies, the present study supported the existence of two principal dimensions of delirium, cognitive and behavioral. Additionally, it extended the results of earlier investigations to a wider group of patients with delirium, suggesting that these dimensions might provide important clues to the neurobiology of delirium.

    Full Text Available Nonmotor symptoms (NMS like neuropsychiatric symptoms, sleep disturbances or autonomic symptoms are a common feature of Parkinson's disease (PD. To explore the existence of groups of NMS and to relate them to PD characteristics, 71 idiopathic non-demented PD out-patients were recruited. Sleep was evaluated by the PD Sleep Scale (PDSS. Several neuropsychiatric, gastrointestinal and urogenital symptoms were obtained from the NMSQuest. Sialorrhea or dysphagia severity was obtained from the Unified PD Rating Scale activities of daily living section. MADRS depression scale was also administered. Exploratory factor analysis revealed the presence of 5 factors, explaining 70% of variance. The first factor included PDSS measurement of sleep quality, nocturnal restlessness, off-related problems and daytime somnolence; the second factor included nocturia (PDSS and nocturnal activity; the third one included gastrointestinal and genitourinary symptoms; the forth one included nocturnal psychosis (PDSS, sialorrhea and dysphagia (UPDRS; and the last one included the MADRS score as well as neuropsychiatric symptoms. Sleep disorders correlated with presence of wearing-off, nocturia with age >69 years, and nocturnal psychosis with levodopa equivalent dose or UPDRS II score. Neuropsychiatric symptoms correlated with UPDRS II+III score and non-tricyclic antidepressants. These results support the occurrence of significant NMS grouping in PD patients.

    One of the most important parts of healthcare system is diagnostics. Nowadays, Indians have become more aware of their health, due to improved and better availability of health related information, increase in medical tourism, and expanding health insurance. The demand for better diagnostic facilities have increased with the increase in lifestyle related diseases, excesses use of chemicals in agriculture practices and change in food habits. It is expected that the Indian diagnostic market will grow from USD $5 billion in the year 2012 to USD $32 billion by the year 2020 with 20% CAGR (India Brand Equity Foundation 2015 ). Today patients have easy access of information regarding the health services and they have become more concerned about it as they look forward to receiving the maximum value for their money. To win the confidence of the patients and to maintain that trust, it is required to deliver the right services to the right person at the right time. The purpose of this study was to develop a scale to measure the service quality at pathology laboratory. A thorough review of literature revealed that there are studies related to healthcare service quality but there is no such established scale to measure service quality of pathology laboratory. Thus, the authors strived to develop a reliable and valid instrument to measure the patients' perception toward pathology laboratory service quality. For this exploratory study was conducted on the sample of 80 patients of the laboratories in Jaipur city. The reliability and factor structures were tested to purify the scale. The findings revealed 13 items, comprising of three dimensions of service quality: responsiveness, tangibility, and reliability.

    The goal of the present study was to examine the transfer of the effects of cognitive strategy training for stroke patients with apraxia from trained to non-trained tasks. In strategy training, the occurrence of transfer is expected as the training programme is aimed, not at relearning specific tasks, but at teaching patients new ways to handle the problems resulting from the impairment. Exploratory analyses were conducted on data previously collected in a randomised controlled trial on the efficacy of the strategy training. A total of 113 left hemisphere stroke patients were randomly assigned to a strategy training group and a group receiving occupational therapy as usual. Assessment of apraxia, motor functioning and activities of daily living (ADL) took place at baseline, after an eight-week treatment period, and five months after baseline. The primary outcome measure consisted of standardised ADL observations of trained and non-trained tasks. The analyses showed that in both treatment groups, the scores on the ADL observations for non-trained tasks improved significantly after eight weeks of training as compared with the baseline score. Change scores of non-trained activities were larger in the strategy training group as compared with the usual treatment group. By using previously collected data we are able to illustrate the potential transfer of treatment effects in a large sample of stroke patients. We found indications for the occurrence of transfer, although the study was not originally designed for the purpose of evaluating transfer. Therefore these results are worth exploring more profoundly. We will further investigate our preliminary conclusions in a new prospective study which is specifically designed to examine the transfer of training effects.

    Explore physician perspectives on their involvement in fall prevention and monitoring for residential care/assisted living (RC/AL) residents. Exploratory cross-sectional study; mailed questionnaire. Four RC/AL communities, North Carolina. Primary physicians for RC/AL residents. Past Behavior and future Intentions of physicians with regard to (1) fall risk assessment and (2) collaboration with RC/AL staff to reduce falls and fall risks among RC/AL residents were explored using Theory of Planned Behavior (TPB) constructs. Predictor variables examined (1) physicians' views on their own responsibilities (Attitude), (2) their views of expectations from important referent groups (Subjective Norms), and (3) perceived constraints on engaging in fall prevention and monitoring (Perceived Behavioral Control). Physicians reported conducting fall risk assessments of 47% of RC/AL patients and collaborating with RC/AL staff to reduce fall risks for 36% of RC/AL patients (Behavior). These proportions increased to 75% and 62%, respectively, for future Intentions. TPB-based models explained approximately 60% of the variance in self-reported Behavior and Intentions. Physician's involvement in fall prevention and monitoring was significantly associated (P beliefs regarding their involvement in fall risk assessment of RC/AL patients and collaboration with RC/AL staff to reduce fall risks of individual patients. Challenges to physician involvement identified in our study are not unique or specific to the RC/AL setting, and instead relate to clinical practice and reimbursement constraints in general.

    To better understand the effects of short-term computer-based cognitive rehabilitation (cCR) on cognitive performances and default mode network (DMN) intrinsic functional connectivity (FC) in cognitively impaired relapsing remitting (RR) multiple sclerosis (MS) patients. Eighteen cognitively impaired RRMS patients underwent neuropsychological evaluation by the Rao's brief repeatable battery and resting-state functional magnetic resonance imaging to evaluate FC of the DMN before and after a short-term (8 weeks, twice a week) cCR. A control group of 14 cognitively impaired RRMS patients was assigned to an aspecific cognitive training (aCT), and underwent the same study protocol. Correlations between DMN and cognitive performances were also tested. After cCR, there was a significant improvement of the following tests: SDMT (p Color-Word Interference Test and FC in the PCC emerged. After aCT, the control group did not show any significant effect either on FC or neuropsychological tests. No significant differences were found in brain volumes and lesion load in both groups when comparing data acquired at baseline and after cCR or aCT. In cognitively impaired RRMS patients, cCR improves cognitive performances (i.e., processing speed and visual and verbal sustained memory), and increases FC in the PCC and IPC of the DMN. This exploratory study suggests that cCR may induce adaptive cortical reorganization favoring better cognitive performances, thus strengthening the value of cognitive exercise in the general perspective of building either cognitive or brain reserve.

    Living with heart failure is a complex situation for family caregivers. Many studies addressing the challenges faced by heart failure family caregivers have already been conducted in Western societal settings. Sociocultural factors and perspectives influence the family caring experience and roles. The ethnic/culturally based differences in family caring behavior make this a subject worth further exploration and clarification. This study explores the experiences of family caregivers in Iran of caring for patients with heart failure. A descriptive, exploratory, and qualitative approach was applied to gain authentic insight into the experiences of participants. Purposive sampling was used to recruit 21 family caregivers from three educational hospitals in Isfahan, Iran. Data were collected using semistructured interviews and field notes. Interviews and field notes were transcribed verbatim and concurrently analyzed. Three major themes emerged from the analysis of the transcripts: caregiver uncertainty, lack of familial and organizational support, and Allah-centered caring. Participants believed that they did not have the basic knowledge related to their disease and drugs. In addition, they received little guidance from the healthcare team. Lack of support and insurance as well as financial issues were major problems faced by the caregivers. They accepted the providence of Allah and noted that Allah always helps them accomplish their caregiving responsibilities. The care performed by the caregivers of patients with heart failure exceeds their individual capabilities. Nurses, other healthcare providers, and health policy makers may use the findings of this study to develop more effective programs to address these challenges and to provide more effective support.Sociocultural factors and perspectives were the primary factors affecting the caregiving experiences of participants in this study. Improved understanding of these factors and perspectives will help healthcare

    Full Text Available CONTEXT: For the diagnosis of the diseases which affect the terminal ileum, the colonoscopy allows macroscopic evaluation and the performing of biopsies. Studies with criteria for the endoscopic and histological characterization of this segment are scarce and there are still some doubts about the need of biopsies in patients with normal ileoscopy. OBJECTIVE: Study the terminal ileum of patients who underwent colonoscopy considering: endoscopic and histological correlation; agreement between results of the initial histological evaluation and slides review, and the chance of subjects with normal ileoscopy with abdominal pain and/or chronic diarrhea to show histological alterations. METHODS: In a prospective study, 111 patients who presented smooth mucosa without enanthema in the endoscopic exam of the terminal ileum were selected. Biopsies of the ileal mucosa of such patients were performed, being the slides routinely examined and reviewed afterwards. RESULTS: The correlation between patients with normal ileoscopy and ileum with preserved histological architecture was of 99.1%. The agreement between initial histological evaluation and slides review calculated by the Kappa test was 0.21. In patients with abdominal pain and/or chronic diarrhea, the chance of showing histological alterations was 2.5 times higher than the others. CONCLUSIONS: The correlation between endoscopic and histological findings was high. The agreement between the initial histologic evaluation and slides review was not satisfactory. The chance of subjects with normal ileoscopy with abdominal pain and/or chronic diarrhea, showing histological alterations was higher in relation to the asymptomatic ones or with other symptoms, although the clinical importance of this datum was not evaluated.CONTEXTO: Para o diagnóstico de doenças que afetam o íleo terminal, a colonoscopia permite avaliação macroscópica e realização de biopsias.

    Social media has become mainstream and a growing number of people use it to share health care-related experiences, for example on health care rating sites. These users' experiences and ratings on social media seem to be associated with quality of care. Therefore, information shared by citizens on social media could be of additional value for supervising the quality and safety of health care services by regulatory bodies, thereby stimulating participation by consumers. The objective of the study was to identify the added value of social media for two types of supervision by the Dutch Healthcare Inspectorate (DHI), which is the regulatory body charged with supervising the quality and safety of health care services in the Netherlands. These were (1) supervision in response to incidents reported by individuals, and (2) risk-based supervision. We performed an exploratory study in cooperation with the DHI and searched different social media sources such as Twitter, Facebook, and healthcare rating sites to find additional information for these incidents and topics, from five different sectors. Supervision experts determined the added value for each individual result found, making use of pre-developed scales. Searches in social media resulted in relevant information for six of 40 incidents studied and provided relevant additional information in 72 of 116 cases in risk-based supervision of long-term elderly care. The results showed that social media could be used to include the patient's perspective in supervision. However, it appeared that the rating site ZorgkaartNederland was the only source that provided information that was of additional value for the DHI, while other sources such as forums and social networks like Twitter and Facebook did not result in additional information. This information could be of importance for health care inspectorates, particularly for its enforcement by risk-based supervision in care of the elderly. Further research is needed to determine

    The relationship between mother and baby is of fundamental importance in the development of cognitive function and emotion. In this study we investigated the effects of affective photographs of a mother and baby (crying or smiling faces) and other stimuli (neutral mother or baby faces) on visual cognitive function in schizophrenic patents. We recorded exploratory eye movements in 22 healthy controls and 22 age-matched schizophrenic patients. Total number of right and left field gaze points (right TNGP, left TNGP) in the visual fields were determined using an eye-mark recorder as subjects viewed affectively charged or neutral photographs (crying, smiling or neutral faces). Left TNGP for all mother photographs (crying, smiling or neutral) were significantly larger in controls than patients, and right TNGP for neutral mother photographs were significantly larger in controls than in patients. Right TNGP for photographs of smiling babies were significantly larger in controls than patients, and left TNGP for photographs of both smiling and crying babies were significantly larger in controls than patients. Within the patient group, right TNGP were significantly larger than left TNGP for all mother photographs (crying, smiling or neutral). Left TNGP for photographs of mothers and babies correlated negatively with negative symptom scores. These results suggest that exploratory eye movements when viewing emotionally laded twin stimuli such as photographs of a mother and baby are a useful marker of visual cognitive function in both healthy controls and schizophrenic patients.

    Physical activity (PA) has a positive effect on the cardiorespiratory fitness, lung cancer symptoms, and quality of life of lung cancer patients. The aim of our study was to identify barriers to, and facilitators of PA in lung cancer patients. We collected data from five patients diagnosed with primary, advanced non-small-cell lung cancer (NSCLC) who were receiving chemotherapy. Choosing a qualitative approach, we conducted an exploratory analysis using the thematic analysis technique to process the data. Seven barriers to, and facilitators of PA were identified and grouped into four categories. We found that psychological and social factors affect patients' willingness and ability to engage in PA, while physiological and environmental factors have an impact on the duration, intensity, and regularity of their PA. Our study highlighted some of the effects that the barriers to PA have on the practice of it in our patient group. Our findings may be used by professionals to design adapted PA programs.

    Full Text Available Objectives: Urinary levels of TWEAK (uTWEAK may be correlated with the degree of lupus nephritis (LN activity. Our objective was to determine the sensitivity and specificity of uTWEAK in Mexican patients with untreated active lupus nephritis. Methods: An exploratory study was performed; four groups of patients were analyzed as follows: 1 patients with systemic lupus erythematosus (SLE without renal activity (SLE-LN, 2 patients with SLE with renal activity (SLE + LN, 3 patients with other types of glomerulopathy (glomerulonephritis, GMN, 4 and healthy patients (controls. Results: In all, 44 patients, with an average age of 35.9 ± 11.5 years, were evaluated. uTWEAK levels were higher in patients with SLE + LN compared with patients in the other groups: SLE + LN 12.88 ± 8.33, SLE-LN 3.12 ± 2.31, GMN 4.36 ± 2.31 and controls 2.41 ± 1.94 pg/mg Cr (p = 0.007. A total of 72.7% of the cases had renal activity index scores above 12, and 90.9% of the cases had scores of chronicity below 6 points. Receiver Operating Characteristic (ROC curve analysis revealed that uTWEAK levels above 4.91 pg/mg Cr had a sensitivity of 81% and a specificity of 75% for the diagnosis of renal activity due to lupus, with an area under the curve of 0.876 (95% CI: 0.75–0.99. However, no significant correlation was observed between the levels of uTWEAK and the histological findings specific to the activity and chronicity associated with SLE. Conclusions: Our study revealed that uTWEAK can adequately distinguish renal activity due to lupus, but cannot predict the degree of histological activity in Mexican patients with active lupus nephropathy. Resumen: Objetivos: Los niveles urinarios de TWEAK (uTWEAK pueden correlacionarse con el grado de actividad de nefritis lúpica (NL.

    The aim of this exploratory study was to assess the impact of clinicians' defense mechanisms-defined as self-protective psychological mechanisms triggered by the affective load of the encounter with the patient-on adherence to a communication skills training (CST). The population consisted of oncology clinicians (N=31) who participated in a CST. An interview with simulated cancer patients was recorded prior and 6 months after CST. Defenses were measured before and after CST and correlated with a prototype of an ideally conducted interview based on the criteria of CST-teachers. Clinicians who used more adaptive defense mechanisms showed better adherence to communication skills after CST than clinicians with less adaptive defenses (F(1, 29) =5.26, p=0.03, d=0.42). Improvement in communication skills after CST seems to depend on the initial levels of defenses of the clinician prior to CST. Implications for practice and training are discussed. Communication has been recognized as a central element of cancer care [1]. Ineffective communication may contribute to patients' confusion, uncertainty, and increased difficulty in asking questions, expressing feelings, and understanding information [2, 3], and may also contribute to clinicians' lack of job satisfaction and emotional burnout [4]. Therefore, communication skills trainings (CST) for oncology clinicians have been widely developed over the last decade. These trainings should increase the skills of clinicians to respond to the patient's needs, and enhance an adequate encounter with the patient with efficient exchange of information [5]. While CSTs show a great diversity with regard to their pedagogic approaches [6, 7], the main elements of CST consist of (1) role play between participants, (2) analysis of videotaped interviews with simulated patients, and (3) interactive case discussion provided by participants. As recently stated in a consensus paper [8], CSTs need to be taught in small groups (up to 10

    Full Text Available This exploratory study assessed the self-management learning needs, experiences, and perspectives of COPD patients treated at a Certified Federal Rural Health Clinic to inform the development of a COPD self-management DVD. A purposive, homogeneous sample of COPD patients participated in focus group interviews. Data from these interviews were referenced to edit a library of Rvision COPD self-management DVDs into a single condensed DVD containing only the most pertinent self-management topics. Patients reported a lack of knowledge and skill development related to purse lipped breathing, controlled coughing, and stress management; while medication management skills were found to be quite adequate. Engaging rural communities in formal qualitative inquiries to describe COPD specific needs for self-management may lead to future use of educational technologies aimed at improving quality of life for these rural, hard to reach populations.

KG, Karlsruhe, Germany Purpose: This study is the first clinical trial aiming to explore the clinical outcomes in burnout patients treated with Rhodiola rosea. The reported capacity of R. rosea to strengthen the organism against stress and its good tolerability offer a promising approach in the treatment of stress-related burnout. The aim of the treatment was to increase stress resistance, thus addressing the source rather than the symptoms of the syndrome and preventing subsequent diseases associated with a history of burnout. The objective of the trial was to provide the exploratory data required for planning future randomized trials in burnout patients in order to investigate the clinical outcomes of treatment with R. rosea dry extract in this target group.Methods: The study was planned as an exploratory, open-label, multicenter, single-arm trial. A wide range of rating scales were assessed and evaluated in an exploratory data analysis to generate hypotheses regarding clinical courses and to provide a basis for the planning of subsequent studies. A total of 118 outpatients were enrolled. A daily dose of 400 mg R. rosea extract (WS® 1375, Rosalin was administered over 12 weeks. Clinical outcomes were assessed by the German version of the Maslach Burnout Inventory, Burnout Screening Scales I and II, Sheehan Disability Scale, Perceived Stress Questionnaire, Number Connection Test, Multidimensional Mood State Questionnaire, Numerical Analogue Scales for different stress symptoms and impairment of sexual life, Patient Sexual Function Questionnaire, and the Clinical Global Impression Scales. Results: The majority of the outcome measures showed clear improvement over time. Several parameters had already improved after 1 week of treatment and continued to improve further up to

    The last 15 years have witnessed considerable progress in the development of decision support interventions (DESIs). However, fundamental questions about design and format of delivery remain. An exploratory, randomized mixed-method crossover study was conducted to compare a DVD- and Web-based DESI. Randomized participants used either the Web or the DVD first, followed by the alternative format. Participants completed a questionnaire to assess decision-specific knowledge at baseline and a questionnaire and structured qualitative interview after viewing each format. Tracking software was used to capture Web utilization. Transcripts were analyzed using integrated inductive and deductive approaches. Quantitative data were analyzed using exploratory bivariate and multivariate analyses. Exploratory knowledge analyses suggest that both formats increased knowledge, with limited evidence that the DVD increased knowledge more than the Web. Format preference varied across participants: 44% preferred the Web, 32% preferred the DVD and 24% preferred 'both'. Patient discussions of preferences for DESI information structure and the importance of a patients' stage of a given decision suggest these characteristics may be important factors underlying variation in utilization, format preferences and knowledge outcomes. Our results suggest that both DESI formats effectively increase knowledge. Patients' perceptions of these two formats further suggest that there may be no single 'best' format for all patients. These results have important implications for understanding why different DESI formats might be preferable to and more effective for different patients. Further research is needed to explore the relationship between these factors and DESI utilization outcomes across diverse patient populations. © 2014 John Wiley & Sons Ltd.

    A 60-year-old male patient with left hilar lung cancer was scheduled to undergo left pneumonectomy or left sleeve lower lobectomy. Preoperative computer tomographic and bronchoscopic examinations revealed that the bronchus (B1) to the right apical segment (S1) was a tracheal bronchus (TB) originating from the trachea approximately 10 mm above the carina. Because the left main bronchus was to be dissected, a right-sided double-lumen tube (DLT) was selected to completely protect the right lung from spillage of secretions or cancer cells from the left lung. The right-sided DLT was placed so as to fit its lateral opening of the bronchial lumen to normal upper branches (B2, B3), while sacrificing ventilation of S1 with an abnormal branch (B1). However, one-lung ventilation (OLV) of the right lung could not be achieved, since a gas leakage from the opened tracheal lumen occurred, most probably due to intra-lobar micro-airway communications between S1 and S2/S3. The DLT was withdrawn until the blue bronchial cuff occluded the orifice of the TB (B1). Although the upper half of the blue bronchial cuff appeared above the tracheal carina, OLV through the two bronchial lumen openings could be achieved due to a specific, slanted doughnut shape of the blue bronchial cuff and the location of the abnormal branch (B1) approximate to the carina. Left pneumonectomy using successful OLV was completed safely without hypoxemia or hypercapnea. Our experience indicates that management of OLV for patients with a thoracheal bronchus needs special considerations of the exact location of the TB and intra-lobar micro-airway communications, in addition to types of scheduled surgical procedures.

    The effects of activated charcoal (AC) mixed with cathartics for gastric decontamination in the management of organophosphate (OP) poisoning remain unknown due to limited clinical evidence. This exploratory study assessed the effectiveness of premixed AC-sorbitol as a treatment for OP poisoning. This retrospective observational case study included patients who either did not receive AC-sorbitol or received a single dose of AC-sorbitol within 24 h after OP ingestion. The patients were divided into three groups: no AC-sorbitol treatment, patients who received AC-sorbitol within 1 h of OP ingestion, and patients who received AC-sorbitol more than 1 h after OP ingestion. Mortality, the development of respiratory failure, and the duration of mechanical ventilation were used as outcome measurements for effectiveness, whereas aspiration pneumonia and electrolyte imbalance were employed as safety measurements. Among 262 patients with OP poisoning, 198 were included. Of these, 133 patients did not receive AC-sorbitol, whereas 14 and 51 patients received AC-sorbitol within 1 h or more than 1 h after ingestion, respectively. The time from ingestion to hospital arrival and time from ingestion to administration of atropine and pralidoxime differed among the groups, whereas other characteristics, including age, amount ingested, and type of ingested OP, were similar among the groups. Univariate and multivariate analysis demonstrated that the administration of AC-sorbitol was not associated with outcome measures for effectiveness and did not significantly increase either aspiration pneumonia or electrolyte imbalances during hospitalization. The administration of AC-sorbitol exerted neither beneficial nor harmful effects on the outcomes of OP-poisoned patients regardless of the time from OP ingestion to administration, compared with those of patients who did not receive AC-sorbitol. However, this study enrolled a small number of patients who received AC-sorbitol; further qualified

    There is increasing recognition that very many hospital patients have dementia but there are many concerns about the quality of care and support they receive. Consequently there have been numerous calls for hospital staff to have dementia training. While cleaning or domestic staff and porters form considerable parts of the hospital workforce they are infrequently considered in discussions of dementia care training and practice. This exploratory study aimed to investigate the experiences of domestic staff and porters working in an acute hospital setting who are in contact regularly with patients with dementia. Semi-structured interviews were undertaken in 2016 with seven domestic staff and five porters in one English acute hospital to investigate their views and experiences. Data were analysed thematically by constant comparison technique and theoretical sampling. Themes were identified and realistic concepts developed. Participants observed that caring attitudes and behaviour in their encounters with patients with dementia are important but challenging to put into practice. Several would have valued more information about dementia. Some noted situations in the hospital stay that seemed particularly difficult for patients with dementia such as travelling to different parts of the hospital for treatments. The study suggests the need for improving the dementia-related knowledge and skills of all non-clinical staff especially those new to the NHS. The impact of witnessing dementia symptoms and distress on emotional well-being requires further research so that ancillary staff can improve the hospital stay of patients with dementia.

    To identify and describe: (1) characteristics of sleep quality, daytime sleepiness, and quality of life (QOL) pre and post implantation of a left ventricular assist device (LVAD); (2) changes in sleep quality, daytime sleepiness, and QOL at baseline and 6 months post implant; and (3) relationships among the sleep quality, daytime sleepiness, and QOL variables. We employed an exploratory research design. Fifteen patients with continuous/non-pulsatile flow LVAD consented to partake in the study. However, only 12 patients completed the baseline and 6-month post-LVAD implant data. We used the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) to measure study variables. Data were analyzed using IBM SPSS 19.0 software. Patients reported worse sleep quality accompanied by daytime sleepiness particularly at baseline, and persisting up to 6 months post LVAD implant. A significant improvement in QOL was observed at 6 months post implant, but remained at poor levels. Correlations among sleep disturbance and daytime dysfunction components of PSQI and global daytime sleepiness (ESS) with QOL were strong (Pearson's correlations r >.60; p values sleep quality, daytime sleepiness, and QOL in patients with LVADs. Our findings offer beginning evidence about the sleep-QOL connection in this population which warrants attention in clinical practice and research. Further research is required to clearly elucidate these phenomena in patients with mechanical circulatory support and other implantable artificial organs.

Data for 453 patients were extracted from the medical records, but 96 cases were excluded because of incomplete data or the patients' not fulfilling the inclusion criteria, thus yielding a total sample of 357 patients. The average patient age was 58 years old (+/- 11.8); the majority (58%) was female. Eight of 10 patients were either overweight or obese. Eighty-five percent reported having at least 1 cardio-metabolic condition. Of these, 72.3% self-reported having hypertension; 38.4%, dyslipidemia; and 37.8%, diabetes. Many patients were not at goal for blood pressure or for lipid and glucose parameters nor were these patients taking any medication for these conditions. Nearly one-third of the participants had a 10% or greater 10-year risk of developing CHD. Compared with women, men were 3.3 times more likely to have a 10-year CHD risk of 10% or greater and 4.2 times more likely to have a risk of 20% or greater. A substantial number of patients had risk factors for developing CHD and were not at goal for specific parameters. Larger scale epidemiological studies should be conducted to assess CHD risk in Puerto Rico so that public health initiatives to reduce this risk might be proposed.

    Characteristics that predispose patients to financial hardship during cancer treatment are poorly understood. We therefore conducted a population-based exploratory analysis of potential factors associated with financial hardship and treatment nonadherence during and following adjuvant chemotherapy for colon cancer. Patients diagnosed with stage III colon cancer between 2008 and 2010 were identified from a population-based cancer registry representing 13 counties in Washington state. Patients were asked to complete a comprehensive survey on treatment-related costs. Patients were considered to have experienced financial hardship if they accrued debt, sold or refinanced their home, borrowed money from friends or family, or experienced a 20% or greater decline in their annual income as a result of treatment-related expenses. Logistic regression analysis was used to investigate factors associated with financial hardship and treatment nonadherence. A total of 284 responses were obtained from 555 eligible patients (response rate, 51.2%). Nearly all patients in the final sample were insured during treatment. In this sample, 38% of patients reported one or more financial hardships as a result of treatment. The factors most closely associated with treatment-related financial hardship were younger age and lower annual household income. Younger age, lower income, and unemployment or disability (which occurred in most instances following diagnosis) were most closely associated with treatment nonadherence. A significant proportion of patients undergoing adjuvant chemotherapy for stage III colon cancer may experience financial hardship, despite having health insurance coverage. Interventions to help at-risk patients early on during therapy may prevent long-term financial adverse effects.

    Improving the quality of healthcare involves collaboration between many different stakeholders. Collaborative learning theory suggests that teaching different professional groups alongside each other may enable them to develop skills in how to collaborate effectively, but there is little literature on how this works in practice. Further, though it is recognised that patients play a fundamental role in quality improvement, there are few examples of where they learn together with professionals. To contribute to addressing this gap, we review a collaborative fellowship in Northwest London, designed to build capacity to improve healthcare, which enabled patients and professionals to learn together. Using the lens of collaborative learning, we conducted an exploratory study of six cohorts of the year long programme (71 participants). Data were collected using open text responses from an online survey (n = 31) and semi-structured interviews (n = 34) and analysed using an inductive open coding approach. The collaborative design of the Fellowship, which included bringing multiple perspectives to discussions of real world problems, was valued by participants who reflected on the safe, egalitarian space created by the programme. Participants (healthcare professionals and patients) found this way of learning initially challenging yet ultimately productive. Despite the pedagogical and practical challenges of developing a collaborative programme, this study indicates that opening up previously restricted learning opportunities as widely as possible, to include patients and carers, is an effective mechanism to develop collaborative skills for quality improvement.

    One of the most troubling symptoms of Alzheimer's disease is the loss of the patient's sense of identity. This loss complicates relationships, increases apathy, and generally impedes quality of life for the patient. We describe a novel in-home ambient display called Biography Theatre that cycles through music, photographs, movies, and narratives drawn from the patient's past and current life. We conducted an exploratory case study with an 84-year-old male with moderate-stage Alzheimer's disease (Mr H). The study consisted of three phases: a baseline phase, a phase wherein autobiographical materials were collected and discussed, and a phase wherein the display was deployed in the home. The patient demonstrated improvement on standardised tests of apathy and positive self-identity, but did not improve on tests of autobiographical memory, anxiety, depression, and general cognition. We also report on caregiver reactions to the intervention and how the display helped them cope with and reinterpret their loved one's condition. This work suggests that interdisciplinary work involving "off the desktop" computing technologies may be a fruitful way to provide rehabilitative benefit for individuals with Alzheimer's disease.

    Families, especially in Eastern and Muslim countries, routinely accept the responsibility of caring for cancer patients. This study describes the transition to the new role of caregiving from the perspective of family caregivers in Iran as part of the current trend of recognizing the experiences of family members of breast cancer patients from different cultural perspectives. A descriptive exploratory qualitative research approach was used to investigate the experiences of family caregivers of patients with breast cancer in the transition to caregiving. The subjects were 23 family caregivers of breast cancer patients referred to cancer centers at Isfahan University hospitals who were selected by purposive sampling. Data was gathered through in-depth interviews. Interview transcripts were analyzed using conventional content analysis with an inductive approach. Data analysis identified the following categories: grasping a new situation without preparation, perceived inefficiency, infinite absence, and abandoned in the role. Caregivers believed that they were not prepared for their new circumstances and did not have the necessary competence and capabilities to meet the challenges of caregiving. They experienced negative consequences resulting from the difficult responsibility of caregiving. Moreover, they believed that they received limited support from relatives, health-care providers, and the community. The transition to the new role of caregiving is affected by experiences specific to the conditions of the caretakers. When these conditions can be understood and identified, it is possible to provide detailed information for policymaking and planning for family-centered care.

    Full Text Available Suicide is a major cause of premature deaths worldwide and belongs to the top priority public health issues. While suicide attempt is the most important risk factor for completed suicide, intervention for suicide attempters (SA have produced mixed results. Since an important proportion of SA request medical care, emergency units (EU are an opportune setting to implement such interventions. This exploratory study evaluated the feasibility and acceptability of a multicomponent intervention for SA admitted to an EU. The intervention consisted of coordination by a case manager of a joint crisis plan (JCP, an early meeting with relatives and the existing care network, as well as phone contacts during 3 months after suicide attempt. Among 107 SA admitted to the emergency unit during the study period, 51 could not be included for logistical reason, 22 were excluded, and intervention was offered to 34. Of these, 15 refused the intervention, which was thus piloted with 19 SA. First-time attempters most frequently declined the intervention. Feasibility and acceptability of phone contacts and case manager were good, while JCPs and meetings were difficult to implement and perceived as less acceptable. Refusal pattern questions the global acceptability and is discussed: JCPs and meetings will have to be modified in order to improve their feasibility and acceptability, especially among first-time attempters.

    Full Text Available Guiding response to neoadjuvant chemotherapy (guided-NACT allows for an adaptative treatment approach likely to improve breast cancer survival. In this study, our primary aim is to explore the expected cost-effectiveness of guided-NACT using as a case study the first randomized controlled trial that demonstrated effectiveness (GeparTrio trial.As effectiveness was shown in hormone-receptor positive (HR+ early breast cancers (EBC, our decision model compared the health-economic outcomes of treating a cohort of such women with guided-NACT to conventional-NACT using clinical input data from the GeparTrio trial. The expected cost-effectiveness and the uncertainty around this estimate were estimated via probabilistic cost-effectiveness analysis (CEA, from a Dutch societal perspective over a 5-year time-horizon.Our exploratory CEA predicted that guided-NACT as proposed by the GeparTrio, costs additional €110, but results in 0.014 QALYs gained per patient. This scenario of guided-NACT was considered cost-effective at any willingness to pay per additional QALY. At the prevailing Dutch willingness to pay threshold (€80.000/QALY cost-effectiveness was expected with 78% certainty.This exploratory CEA indicated that guided-NACT (as proposed by the GeparTrio trial is likely cost-effective in treating HR+ EBC women. While prospective validation of the GeparTrio findings is advisable from a clinical perspective, early CEAs can be used to prioritize further research from a broader health economic perspective, by identifying which parameters contribute most to current decision uncertainty. Furthermore, their use can be extended to explore the expected cost-effectiveness of alternative guided-NACT scenarios that combine the use of promising imaging techniques together with personalized treatments.

    The aim of this study was to explore the internal structure of an instrument assessing dental students' confidence in their ability to communicate with patients in six specific circumstances (anxious, in pain, etc.) using exploratory factor analysis. In a Communication in the Dental Health Care Setting course at a U.S. dental school, second-year dental students in two years (2013 and 2014) responded to the six items on a survey instrument. Of the total 123 students, 122 fully completed the instrument, for a response rate of 99%. Analysis of the results identified a unidimensional scale with regards to patient-specific communication self-efficacy and explained 74% of the total variance. The scale had good internal consistency reflected by high Cronbach's alpha (α=0.929, 95% CI [0.907, 0.947]). These findings suggest the instrument may be a useful tool in assessing the development of patient communication skills in second-year dental students following a course in communication. Further exploration utilizing confirmatory analysis, determining predictive validity, and assessing convergent and discriminant evidence is warranted.

    Full Text Available Objective. To identify the actions of family members who accompany adult hospitalized patients and to describe the nursing team's role regarding that person. Methodology. In this qualitative, descriptive and exploratory research, a questionnaire was applied to 30 nursing team members at a teaching hospital located in the State of Rio de Janeiro, using open questions. To interpret the answers, thematic analysis was applied to categorize the identified qualitative variables. Results. Eighty-nine percent of the participants were female. When analyzing the information contained in the answers to the questionnaire, two types of actions were found: the actions the companion can perform for his/her relative and the actions the nursing team needs to perform. In each action, the following categories were verified: affective dimension, practical dimension, moral dimension and inclusion of the family in care. According to the nursing team, the companion plays a very important role in emotional support and help with the patient's basic hygiene, although this care should be offered under nursing orientation. Conclusion. Family companions and nursing team members work together to improve the quality of patient care, with positive reflections for their integration in hospital care, which will enhance its continuity in the home-care context.

    The growth in the volume of online patient feedback, including online patient ratings and comments, suggests that patients are embracing the opportunity to review online their experience of receiving health care. Very little is known about health care professionals' attitudes toward online patient feedback and whether health care professionals are comfortable with the public nature of the feedback. The aim of the overall study was to explore and describe general practitioners' attitudes toward online patient feedback. This paper reports on the findings of one of the aims of the study, which was to explore and understand the concerns that general practitioners (GPs) in England have about online patient feedback. This could then be used to improve online patient feedback platforms and help to increase usage of online patient feedback by GPs and, by extension, their patients. A descriptive qualitative approach using face-to-face semistructured interviews was used in this study. A topic guide was developed following a literature review and discussions with key stakeholders. GPs (N=20) were recruited from Cambridgeshire, London, and Northwest England through probability and snowball sampling. Interviews were transcribed verbatim and analyzed in NVivo using the framework method, a form of thematic analysis. Most participants in this study had concerns about online patient feedback. They questioned the validity of online patient feedback because of data and user biases and lack of representativeness, the usability of online patient feedback due to the feedback being anonymous, the transparency of online patient feedback because of the risk of false allegations and breaching confidentiality, and the resulting impact of all those factors on them, their professional practice, and their relationship with their patients. The majority of GPs interviewed had reservations and concerns about online patient feedback and questioned its validity and usefulness among other things

    Full Text Available Abstract Background When detected, HIV can be effectively treated with antiretroviral therapy. Nevertheless in the U.S. approximately 25% of those who are HIV-infected do not know it. Much remains unknown about how to increase HIV testing rates. New Internet outreach methods have the potential to increase disease awareness and screening among patients, especially as electronic personal health records (PHRs become more widely available. In the US Department of Veterans' Affairs medical care system, 900,000 veterans have indicated an interest in receiving electronic health-related communications through the PHR. Therefore we sought to evaluate the optimal circumstances and conditions for outreach about HIV screening. In an exploratory, qualitative research study we examined patient and provider perceptions of Internet-based outreach to increase HIV screening among veterans who use the Veterans Health Administration (VHA health care system. Findings We conducted two rounds of focus groups with veterans and healthcare providers at VHA medical centers. The study's first phase elicited general perceptions of an electronic outreach program to increase screening for HIV, diabetes, and high cholesterol. Using phase 1 results, outreach message texts were drafted and then presented to participants in the second phase. Analysis followed modified grounded theory. Patients and providers indicated that electronic outreach through a PHR would provide useful information and would motivate patients to be screened for HIV. Patients believed that electronic information would be more convenient and understandable than information provided verbally. Patients saw little difference between messages about HIV versus about diabetes and cholesterol. Providers, however, felt patients would disapprove of HIV-related messages due to stigma. Providers expected increased workload from the electronic outreach, and thus suggested adding primary care resources and devising

    The proportion of lung cancers with an occupational origin has been estimated to be between 10 and 20%. They are largely under-reported, as 60% are not compensated as occupational disease. Although most patients are not familiar with the process of compensation, other factors could explain this under-reporting. The aim of this study was to identify psychosocial factors that could impact patients with occupational lung cancer to claim for compensation. We conducted a case study involving semi-structured interviews with eight lung cancer patients enrolled in a cohort designed to systematically screen occupational exposures and propose claims for compensation to work-related cancer patients. Seven interviewed patients were familiar with occupational cancers, but most of them did not believe that past exposure could be related to their current disease. Patients associated compensation claims with a long and complex procedure for an abstract purpose. Several patients expressed a certain attachment to their employers. Interviewed patients often considered compensation claims to be a grievance procedure against the employers whom they did not consider to be responsible for their disease. Lung cancer is itself an obstacle to compensation considering the aggressive treatments and related adverse events, the poor medium-term prognosis and the predominant role of smoking in the etiology of the disease. Patients mentioned the financial compensation and the role of healthcare professionals as key elements to motivate them to claim for compensation.

    Abnormalities in the somatosensory system are increasingly being recognized in patients with dystonia. The aim of this study was to investigate whether sensory abnormalities are confined to the dystonic body segments or whether there is a wider involvement in patients with idiopathic dystonia. For this purpose, we recruited 20 patients, 8 had generalized, 5 had segmental dystonia with upper extremity involvement, and 7 had cervical dystonia. In total, there were 13 patients with upper extremity involvement. We used Quantitative Sensory Testing (QST) at the back of the hand in all patients and at the shoulder in patients with cervical dystonia. The main finding on the hand QST was impaired cold detection threshold (CDT), dynamic mechanical allodynia (DMA), and thermal sensory limen (TSL). The alterations were present on both hands, but more pronounced on the side more affected with dystonia. Patients with cervical dystonia showed a reduced CDT and hot detection threshold (HDT), enhanced TSL and DMA at the back of the hand, whereas the shoulder QST only revealed increased cold pain threshold and DMA. In summary, QST clearly shows distinct sensory abnormalities in patients with idiopathic dystonia, which may also manifest in body regions without evident dystonia. Further studies with larger groups of dystonia patients are needed to prove the consistency of these findings.

    2009-01-01

    Initiating and adjusting insulin treatment for people with type 2 diabetes (T2D) requires frequent clinician contacts both face-to-face and by telephone. We explored the use of a telehealth system to offer additional support to these patients. Twenty-three patients with uncontrolled T2D were recruited from nine general practices to assess the feasibility and acceptability of telehealth monitoring and support for insulin initiation and adjustment. The intervention included a standard algorithm for self-titration of insulin dose, a Bluetooth enabled glucose meter linked to a mobile phone, an integrated diary to record insulin dose, feedback of charted blood glucose data and telehealth nurse review with telephone follow-up. Additional contact with patients was initiated when no readings were transmitted for >3 days or when persistent hyper- or hypoglycaemia was identified. Reponses of patients and clinicians to the system were assessed informally. The mean (SD) patient age was 58 years (12) with 78% male. The mean (SD) diabetes duration was 6.4 years (4.5), HbA1c at baseline was 9.5% (2.2), and the decrease in HbA1c at three months was 0.52% (0.91) with an insulin dose increase of 9 units (26). A mean (SD) of 160 (93) blood glucose readings was transmitted per patient in these three months. Practice nurses and general practitioners (GPs) viewed the technology as having the potential to improve patient care. Most patients were able to use the equipment with training and welcomed review of their blood glucose readings by a telehealth nurse. Although the concept of telehealth monitoring is unfamiliar to most patients and practice nurses, the technology improved the support available for T2D patients commencing insulin treatment.

    2018-01-01

    Full Text Available Background: There has been very little focus on understanding the experiences of people suffering from mental illness during their treatment in the outpatient and inpatient treatment facilities. Majority of the decisions regarding their treatment are taken by the mental health professionals in consultation with the caregivers, and the patient remains a passive recipient of the services. It is commonly seen that patients refuse admission in the psychiatry ward even when clinical needs warrant admission. Aim: The aim of the current study was to explore the perception of patients regarding admission in the psychiatry ward and the fears associated with indoor treatment facility. Methodology: A semistructured interview schedule was administered to 110 patients undergoing treatment from outpatient services to study their attitude toward treatment in psychiatry ward. Results: A large number of patients perceived psychiatry ward as a hostile place with unfriendly atmosphere and dark and unsupportive environment. However, the patients who had been admitted in the past found it less scary and appreciated good and friendly behavior of the staff in the ward. Conclusion: Negative perception of inpatient treatment and psychiatry wards is still highly prevalent among the patients. With growing focus on reducing stigma about psychiatric illnesses, dispelling the myths related to treatment in wards is the need of the hour.

    Patients with hyperventilation syndrome (HVS) report severe symptom-related suffering and often complain from insufficient medical attention. However, quality of life data in this context are scarce. We aimed at assessing the health-related quality of life (HRQoL) of HVS patients. Twenty-one HVS patients with extensive cardiorespiratory workup including cardiopulmonary exercise testing (CPET) filled in the generic SF-36 questionnaire and the results were compared to French normal values. Correlations between SF36 dimensions and clinical and functional data were established. All SF-36 scores were markedly decreased in HVS patients compared to healthy subjects: Physical Functioning: 44 ± 24, Social Functioning: 57 ± 27, Role Physical: 21 ± 32, Role Emotional: 48 ± 42, Mental Health: 51 ± 27, Vitality: 34 ± 20, Body Pain: 41 ± 21, General Health: 42 ± 21. These figures were all significantly lower in the HVS patients respective to the normal reference population. They were also lower than corresponding values published in patients with asthma or chronic obstructive pulmonary disease (COPD). "Vitality" and "Physical Functioning" scores were correlated with Nijmegen score (r = -0.594, p = 0.047) and peak respiratory frequency during CPET (r = -0.644, p = 0.019). The SF-36 Social Functioning score was correlated with the ventilatory threshold (r = 0.629, p = 0.034), peak V'E/V'CO2 (ventilation/CO2 production) (r = 0.650, p = 0.016) and peak PaCO2 (r = -0.664, p = 0.027). In conclusion, this study shows that HRQoL can be severely impaired in patients with HVS, which is one more reason to take this condition seriously. Copyright © 2013 Elsevier Ltd.

    Tan, Maria C; Maggio, Lauren A

    2013-01-01

    The research explored the roles of practicing clinical librarians embedded in a patient care team. Six clinical librarians from Canada and one from the United States were interviewed to elicit detailed descriptions of their clinical roles and responsibilities and the context in which these were performed. Participants were embedded in a wide range of clinical service areas, working with a diverse complement of health professionals. As clinical librarians, participants wore many hats, including expert searcher, teacher, content manager, and patient advocate. Unique aspects of how these roles played out included a sense of urgency surrounding searching activities, the broad dissemination of responses to clinical questions, and leverage of the roles of expert searcher, teacher, and content manager to advocate for patients. Detailed role descriptions of clinical librarians embedded in patient care teams suggest possible new practices for existing clinical librarians, provide direction for training new librarians working in patient care environments, and raise awareness of the clinical librarian specialty among current and budding health information professionals.

    Full Text Available The aim of this study is to explore the information needs of men with prostate cancer and their partners retrospectively at various points in the treatment process. An online questionnaire was used to collect information from men with prostate cancer and their partners about information needs, and when these developed. Readers of a Prostate Care Cookbook and members of a Prostate Cancer Charity were invited to participate: 73 men with prostate cancer and 25 partners completed the questionnaire. Responses showed that participants develop their information needs close to diagnosis. Less educated men with prostate cancer and partners developed their needs closer to the time after diagnosis than those with higher education. Partners develop an interest on information related to treatment and interaction earlier than patients. Patients prioritised treatment and disease-specific information. Patients and partners differ in how their information needs develop. Medical information is prioritized by patients as opposed to practical information by partners. Health care provision can be tailored to meet the different needs of prostate cancer patients and their partners at different times in the treatment process

    Host immune responses to Mycobacterium tuberculosis are generally able to contain infection and maintain a delicate balance between protection and immunopathology. A shift in this balance appears to underlie active disease observed in about 10% of infected individuals. Effects of local inflammation, combined with anti-M. tuberculosis systemic immune responses, are directly detectable in peripheral circulation, without ex vivo stimulation of blood cells or biopsy of the affected organs. We studied plasma immunomodulator and antibody biomarkers in patients with active pulmonary tuberculosis (TB) by a combination of multiplex microbead immunoassays and computational tools for data analysis. Plasma profiles of 10 immunomodulators and antibodies against eight M. tuberculosis antigens (previously reported by us) were examined in active pulmonary TB patients in a country where TB is endemic, Pakistan. Multiplex analyses were performed on samples from apparently healthy individuals without active TB from the same community as the TB patients to establish the assay baselines for all analytes. Over 3,000 data points were collected from patients (n = 135) and controls (n = 37). The data were analyzed by multivariate and computer-assisted cluster analyses to reveal patterns of plasma immunomodulators and antibodies. This study shows plasma profiles that in most patients represented either strong antibody or strong immunomodulator biomarkers. Profiling of a combination of both immunomodulators and antibodies described here may be valuable for the analysis of host immune responses in active TB in countries where the disease is endemic.

    This paper reports on an exploratory study of intra-organisational knowledge brokers working within three large acute hospitals in the English National Health Services. Knowledge brokering is promoted as a strategy for supporting knowledge sharing and learning in healthcare, especially in the diffusion of research evidence into practice. Less attention has been given to brokers who support knowledge sharing and learning within healthcare organisations. With specific reference to the need for learning around patient safety, this paper focuses on the structural position and role of four types of intra-organisational brokers. Through ethnographic research it examines how variations in formal role, location and relationships shape how they share and support the use of knowledge across organisational and occupational boundaries. It suggests those occupying hybrid organisational roles, such as clinical-managers, are often best positioned to support knowledge sharing and learning because of their 'ambassadorial' type position and legitimacy to participate in multiple communities through dual-directed relationships.

    Mobile mental health has a potential to improve the recognition and management of Chinese patients with depression. Currently, evidence regarding ecological momentary assessment (EMA) for depressive disorder mostly originates from Western studies. Herein, we examined the validity of smartphone-based EMA for depression in Chinese patients and explored the determinants of use. A smartphone application, iHOPE, was used to perform daily EMA of depression, anxiety, sleep and cognitive performance. Outpatients with depressive disorder were recruited to use iHOPE for 8 weeks. Clinical characteristics and smartphone use patterns were assessed at baseline. We enrolled 59 Chinese patients with depression. In 8 weeks, participants interacted with iHOPE for an average of 10.8 (SD=12.3) days; a trend of decreased frequency of use (p=0.03) was observed. Scores of HAM-D at baseline was associated with, of the first 2 weeks, scores of PHQ-9 (p=0.005), EMA of depression (p=0.003) and anxiety (psleep quality (p=0.023). Among the demographic, clinical and smartphone-use variables examined, only limited internet package for smartphone (smartphone-based EMA in Chinese patients with depression. Level of engagement needs to be improved before determining its clinical usefulness. Copyright © 2016 Elsevier B.V. All rights reserved.

    Although several reports have suggested that patient-generated data from Internet sources could be used to improve drug safety and pharmacovigilance, few studies have identified such data sources in Japan. We introduce a unique Japanese data source: tōbyōki, which translates literally as "an account of a struggle with disease." The objective of this study was to evaluate the basic characteristics of the TOBYO database, a collection of tōbyōki blogs on the Internet, and discuss potential applications for pharmacovigilance. We analyzed the overall gender and age distribution of the patient-generated TOBYO database and compared this with other external databases generated by health care professionals. For detailed analysis, we prepared separate datasets for blogs written by patients with depression and blogs written by patients with rheumatoid arthritis (RA), because these conditions were expected to entail subjective patient symptoms such as discomfort, insomnia, and pain. Frequently appearing medical terms were counted, and their variations were compared with those in an external adverse drug reaction (ADR) reporting database. Frequently appearing words regarding patients with depression and patients with RA were visualized using word clouds and word cooccurrence networks. As of June 4, 2016, the TOBYO database comprised 54,010 blogs representing 1405 disorders. Overall, more entries were written by female bloggers (68.8%) than by male bloggers (30.8%). The most frequently observed disorders were breast cancer (4983 blogs), depression (3556), infertility (2430), RA (1118), and panic disorder (1090). Comparison of medical terms observed in tōbyōki blogs with those in an external ADR reporting database showed that subjective and symptomatic events and general terms tended to be frequently observed in tōbyōki blogs (eg, anxiety, headache, and pain), whereas events using more technical medical terms (eg, syndrome and abnormal laboratory test result) tended to be

    Uremic pruritus is a common and deleterious condition among hemodialysis (HD) patients. Central gating of μ/κ opiate circuitry plays an important role in mediating and countering pruritogenic sensation. The objective of this study was to assess the safety and pharmacokinetics (PK) of the mixed μ-antagonist/κ-agonist nalbuphine, administered orally as nalbuphine HCl extended release (ER) tablets in HD patients, and explore its effect on pruritus. In this open-label multiple escalating dose study, 15 HD patients with pruritus and 9 matched healthy subjects were enrolled. Nalbuphine HCl ER dose was escalated from 30 mg QD to 240 mg BID over 15 days. A full PK profile was obtained under dialysis and non-dialysis conditions as a function of dose. Clearance during dialysis was determined by sampling dialysate and arterial/venous blood during dialysis. Pruritus severity was assessed twice daily using a Visual Analog Scale (VAS). Safety monitoring included extensive monitoring of EKG, blood pressure, and pulse oximetry. In HD patients, nalbuphine concentration peaked within 4-9 hours and attained steady state within 2-3 days, with no significant accumulation. Mean half-life was 14.2 hours, mean Cmax and AUCtau ranged between 13 and 83 ng/mL and 118 and 761 ng∙h/mL, respectively, with exposure increasing in a nearly dose-proportional fashion. Exposure in HD patients was about 2-fold higher than in healthy subjects. There was no meaningful difference between exposure on dialysis and non-dialysis days with 1% or less of the dose removed by dialysis. Nalbuphine suppressed itch in a dose-dependent manner, reducing mean VAS score from 4.0 to 1.2 at 180 mg and 0.4 at 240 mg. Nalbuphine HCl ER tablets can be safely administered to HD patients without dose adjustment up to 240 mg BID and may hold promise in treating uremic pruritus.

    Employment-related issues have been largely overlooked in cancer patients needing palliative care. These issues may become more relevant as cancer evolves into more of a chronic illness and palliative care is provided independent of stage or prognosis. To characterize the employment situations of working-age palliative care patients. Cross-sectional survey setting/subjects: Consecutive sample of 112 patients followed in palliative care outpatient clinics at a comprehensive cancer center. Thirty-seven-item self-report questionnaire covering demographics, clinical status, and work experiences since diagnosis. The commonest cancer diagnoses were breast, colorectal, gynecological, and lung. Eighty-one percent had active disease. Seventy-four percent were on treatment. Eighty percent recalled being employed at the time of diagnosis, with 65% working full time. At the time of the survey, 44% were employed and 26% were working full time. Most participants said work was important, made them feel normal, and helped them feel they were "beating the cancer". Factors associated with being employed included male gender, self-employed, and taking less than three months off work. Respondents with pain and/or other symptoms were significantly less likely to be working. On multivariate analysis, only pain (odds ratio [OR] 8.16, p gender (OR 2.07), self-employed (OR 3.07), and current chemotherapy (OR 1.81) were included in the model, but were not statistically significant in this small sample. Work may be an important issue for some palliative care patients. Additional research is needed to facilitate ongoing employment for those who wish or need to continue working.

    For people who are experiencing financial hardship, a cancer diagnosis can be devastating. For others, cancer may exacerbate financial stress, thereby influencing their livelihood, their ability to maintain employment benefits including health insurance, manage financial obligations, and participate meaningfully in cancer treatment. This study examined how vulnerabilities in psychosocial situations affect financial quality of life within the larger context of health-care decision making through a survey conducted with a cross-sectional availability sample of 90 cancer patients. Results from the multiple regression analysis found that health insurance adequacy, fewer perceived barriers to care, and reduced financial stress are significant predictors of better financial quality of life in this sample. Oncology social workers and other disciplines involved in psychosocial treatment with patients with cancer must assess and address financial and logistic aspects of life in order to provide comprehensive cancer care that meets all needs. Collaborative coordination with patients with cancer and their families to intervene psychosocially, medically, and financially are critical components of sound psychosocial and medical practice.

    Out of 134 patients irradiated below the diaphragm to a dose of 40 Gy for Hodgkin's disease at the Institut Gustave-Roussy, 19 (14%) were subsequently found to present with radiation injuries of the gastrointestinal tract. Since five patients presented with two different injuries, 24 radiolesions were observed. Most of them (17 out of 24) were gastric or duodenal. Twelve (out of 24) were ulcers. Nine patients required surgery. A complete cure of the radiation injuries was obtained in 15 out of 19 patients. Sex, age, stage, histology or initial chemotherapy were not found to play a role in the occurrence of radiation damage. On the contrary, the role of a previous exploratory laparotomy appeared important; for the patients who underwent laparotomy and irradiation, the complication rate was 23%. For the patients treated by irradiation alone, the complication rate was 7% (p < 0.01). Fractionation was found to be another important parameter: for 52 patients treated using 3 weekly fractions of 3.3 Gy, the complication rate was 25% compared to 8% (p < 0.01) for 76 patients treated using 4 weekly fractions of 2.5 Gy. Combining these two factors, the authors found a 42% complication rate for the group of patients who underwent laparotomy and who were treated by means of 3 fractions of 3.3 Gy per week, whereas patients irradiated using 4 weekly fractions of 2.5 Gy, without any previous laparotomy, has only a 5% complication risk (p < 0.001).

    Most studies on barriers and facilitators to implementation of patient decision aids (PDAs) are conducted in the west; hence, the findings may not be transferable to developing countries. This study aims to use a locally developed insulin PDA as an exemplar to explore the barriers and facilitators to implementing PDAs in Malaysia, an upper middle-income country in Asia. Qualitative methodology was adopted. Nine in-depth interviews (IDIs) and three focus group discussions (FGDs) were conducted with policymakers (n = 6), medical officers (n = 13), diabetes educators (n = 5) and a nurse, who were involved in insulin initiation management at an academic primary care clinic. The interviews were conducted with the aid of a semi-structured interview guide based on the Theoretical Domains Framework. The interviews were audio-recorded, transcribed verbatim and analyzed using a thematic approach. Five themes emerged, and they were lack of shared decision-making (SDM) culture, role boundary, lack of continuity of care, impact on consultation time and reminder network. Healthcare providers' (HCPs) paternalistic attitude, patients' passivity and patient trust in physicians rendered SDM challenging which affected the implementation of the PDA. Clear role boundaries between the doctors and nurses made collaborative implementation of the PDA challenging, as nurses may not view the use of insulin PDA to be part of their job scope. The lack of continuity of care might cause difficulties for doctors to follow up on insulin PDA use with their patient. While time was the most commonly cited barrier for PDA implementation, use of the PDA might reduce consultation time. A reminder network was suggested to address the issue of forgetfulness as well as to trigger interest in using the PDA. The suggested reminders were peer reminders (i.e. HCPs reminding one another to use the PDA) and system reminders (e.g. incorporating electronic medical record prompts, displaying posters

    Various north-western European health-care systems encourage patients to make an active choice of health-care provider. This study explores, qualitatively, patients' hospital selection processes and provides insight into the reasons why patients do or do not make active choices. Semi-structured individual interviews were conducted with 142 patients in two departments of three Dutch hospitals. Interviews were recorded, transcribed and analysed in accordance with the grounded theory approach. Three levels of choice activation were identified - passive, semi-active and active. The majority of the patients, however, visited the default hospital without having used quality information or considered alternatives. Various factors relating to patient, provider and health-care system characteristics were identified that influenced patients' level of choice activation. On the whole, the patients interviewed could be classified into five types with regard to how they chose, or 'ended up at' a hospital. These types varied from patients who did not have a choice to patients who made an active choice. A large variation exists in the way patients choose a hospital. However, most patients tend to visit the default without being concerned about choice. Generally, they do not see any reason to choose another hospital. In addition, barriers exist to making choices. The idea of a patient who actively makes a choice originates from neoclassical microeconomic theory. However, policy makers may try in vain to bring principles originating from this theory into health care. Even so, patients do value the opportunity of attending 'their' own hospital. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

    We conducted a preliminary investigation into dimensions of stigma and their relation to disease concealment in a sample of American adults living with multiple sclerosis (MS). Fifty-three adults with MS in the United States completed an online survey assessing anticipated, internalized, and isolation stigma, as well as concealment. Responses to all the scales were relatively low, on average, but above scale minimums (P stigma and concealment were highest. Anticipated stigma strongly predicted concealment. Many adults living with MS may be concerned that they will be the target of social stigma because of their illness. These concerns are associated with disease concealment. More research is needed to investigate how MS stigma and concealment may be independent contributors to health in patients with MS.

    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 Clear communication about the possible outcomes of proposed medical interventions is an integral part of medical care. Despite its importance, there have been few studies comparing different formats for presenting probabilistic information to patients, especially when small probabilities are involved. The purpose of this study was to explore the potential usefulness of several new small-risk graphic communication formats. Methods Information about the likelihoods of cancer and cancer prevention associated with two hypothetical cancer screening programs were used to create an augmented bar chart, an augmented grouped icon display, a flow chart, and three paired combinations of these formats. In the study scenario, the baseline risk of cancer was 53 per 1,000 (5.3%. The risk associated with cancer screening option A was 38 per 1,000 (3.8% and the risk associated with screening option B was 29 per 1,000 (2.9%. Both the augmented bar chart and the augmented grouped icon display contained magnified views of the differences in cancer risk and cancer prevention associated with the screening programs. A convenience sample of 29 subjects (mean age 56.4 years; 76% men used the Analytic Hierarchy Process (AHP to indicate their relative preferences for the six formats using 15 sequential paired comparisons. Results The most preferred format was the combined augmented bar chart + flow diagram (mean preference score 0.43 followed by the combined augmented icon + augmented bar chart format (mean preference score 0.22. The overall differences among the six formats were statistically significant: Kruskal-Wallis Chi Square = 141.4, p Conclusion These findings suggest that patients may prefer combined, rather than single, graphic risk presentation formats and that augmented bar charts and icon displays may be useful for conveying comparative information about small risks to clinical decision makers. Further research to confirm and extend these

    Care and education have much in common, and work in the healthcare sector is closely associated with learning and teaching. It is felt that many in the healthcare and medical services are not aware of their pedagogic skills and how they can be developed. FRAME OF REFERENCE: Belonging to a community of practice means that you share perspectives, methods and language. The aim is to describe the pedagogical discourse by identifying pedagogical processes and studying the staff's awareness of such processes or situations in which a pedagogical approach would be useful in their work with patients and next of kin. A qualitative study based on individual and group interviews. The analysis is directed by grounded theory. The pedagogical processes varied in length and quality. Most were unplanned and were usually embedded in treatment. The pedagogical process is linear (planning, goal setting, teaching and evaluating) in an educational setting but we found that the beginning and end can be unclear and the goals can be vague or non-existent. The pedagogical process is best described using the concepts Read, Guide and Provide learning support. The pedagogical discourse in healthcare is almost silent. Data indicate that at the collective level there is very little support for professional development of pedagogical ability. Tacit knowledge may therefore remain silent even though it may be possible to formulate and describe it. There is a strong need to focus on the pedagogical parts of the work and to encourage and support the development of professional pedagogical knowledge.

  9. Context factors in general practitioner - patient encounters and their impact on assessing communication skills - an exploratory study

    2013-01-01

    Background Assessment of medical communication performance usually focuses on rating generically applicable, well-defined communication skills. However, in daily practice, communication is determined by (specific) context factors, such as acquaintance with the patient, or the presented problem. Merely valuing the presence of generic skills may not do justice to the doctor’s proficiency. Our aim was to perform an exploratory study on how assessment of general practitioner (GP) communication performance changes if context factors are explicitly taken into account. Methods We used a mixed method design to explore how ratings would change. A random sample of 40 everyday GP consultations was used to see if previously identified context factors could be observed again. The sample was rated twice using a widely used assessment instrument (the MAAS-Global), first in the standard way and secondly after context factors were explicitly taken into account, by using a context-specific rating protocol to assess communication performance in the workplace. In between first and second rating, the presence of context factors was established. Item score differences were calculated using paired sample t-tests. Results In 38 out of 40 consultations, context factors prompted application of the context-specific rating protocol. Mean overall score on the 7-point MAAS-Global scale increased from 2.98 in standard to 3.66 in the context-specific rating (p communication was set at 3.17. Conclusions Applying the protocol, the mean overall score rose above the level set in an earlier study for the MAAS-Global scores to represent ‘adequate GP communication behaviour’. Our findings indicate that incorporating context factors in communication assessment thus makes a meaningful difference and shows that context factors should be considered as ‘signal’ instead of ‘noise’ in GP communication assessment. Explicating context factors leads to a more deliberate and transparent rating of

    Fatigue is common among cancer survivors, but fatigue in thyroid cancer (TC) survivors may be under-appreciated. This study investigated the severity and prevalence of moderate and severe fatigue in TC survivors. Potential predictive factors, including physical activity, were explored. A cross-sectional, written, self-administered TC patient survey and retrospective chart review were performed in an outpatient academic Endocrinology clinic in Toronto, Canada. The primary outcome measure was the global fatigue score measured by the Brief Fatigue Inventory (BFI). Physical activity was evaluated using the International Physical Activity Questionnaire-7 day (IPAQ-7). Predictors of BFI global fatigue score were explored in univariate analyses and a multivariable linear regression model. The response rate was 63.1% (205/325). Three-quarters of the respondents were women (152/205). The mean age was 52.5 years, and the mean time since first TC surgery was 6.8 years. The mean global BFI score was 3.5 (standard deviation 2.4) out of 10 (10 is worst). The prevalence of moderate-severe fatigue (global BFI score 4.1-10 out of 10) was 41.4% (84/203). Individuals who were unemployed or unable to work due to disability reported significantly higher levels of fatigue compared to the rest of the study population, in uni-and multivariable analyses. Furthermore, increased physical activity was associated with reduced fatigue in uni- and multivariable analyses. Other socio-demographic, disease, or biochemical variables were not significantly associated with fatigue in the multivariable model. Moderate or severe fatigue was reported in about 4/10 TC survivors. Independent predictors of worse fatigue included unemployment and reduced physical activity.

    This study aimed to investigate psychosocial functioning and different dimensions of theory of mind (ToM) in people with bulimia nervosa (BN) and Eating Disorder Not Otherwise Specified-BN type (EDNOS-BN). Psychosocial functioning and ToM were assessed in a sample of young adult females, 16 BN and 16 EDNOS-BN outpatients and 16 healthy controls (HCs). They were assessed using the Eating Disorder Inventory-Symptom Checklist-2 (EDI-2 SC) for evaluating psychological traits associated with eating disorders; the Symptom Checklist-90-Revised (SCL-90-R) for evaluating psychopathological status; and the Theory of Mind Assessment Scale (Th.o.m.a.s.), a semi-structured interview aimed at assessing a person's different dimensions of ToM. The BN and EDNOS-BN groups exhibited worse performance than the control group on all dimensions of the SCL-90-R, and on all dimensions of the EDI-2 SC. The only difference for perfectionism was that BN obtained higher scores than EDNOS-BN group. Our results also revealed an impairment of third-person and second-order ToM in patients with bulimia (BN and EDNOS-BN) with respect to control subjects. These preliminary data have important implications for future empirical work, in that they provide valuable information regarding the importance of investigating the various facets of ToM ability separately, in order to provide a more detailed profile of ToM functioning in the clinical samples. © 2013 The British Psychological Society.

    Full Text Available Propósito del estudio: proponer un modelo antropométrico que permita evaluar de forma homogénea la evolución de los pacientes sometidos a distracción osteogénica mandibular. Métodos: se realizó un estudio previo en el que se constató la ausencia de un protocolo internacional que estandarice el estudio y evaluación de los resultados obtenidos con distracción osteogénica mandibular y que permita evaluar la recidiva esqueletal a largo plazo. Se tomó como elementos de medidas los estudios cefalométricos angulares y lineales de McNamara y Steiner y se incluyó el panorograma de Simoes. Se diseñó un modelo matemático con fórmulas que permiten evaluar la distracción obtenida en rama y cuerpo, así como la efectividad del tratamiento y la estabilidad a largo plazo. Se propuso además una valoración de los cambios oclusales obtenidos. Resultados: el modelo antropométrico propuesto constituye un instrumento útil para implementar el método científico en el estudio y evaluación de los pacientes tratados con distracción osteogénica mandibular. Conclusiones: el modelo antropométrico propuesto es un método idóneo para evaluar, de forma homogénea, la evolución de los pacientes sometidos a distracción osteogénica mandibular.Aim: To propose a anthropometric model allows in a homogenous way to assess the course of patients underwent to mandibular osteogenic distraction. Methods: A prior study was carried out which allow us to confirm the lack of a international protocol generalizing the study and the evaluation of results achieved with the mandibular osteogenic distraction and also allows to assess the long-term skeletal relapse.

    Digital technology (e-health or 'blended' care), combined with evidence-based face-to-face CBT, is becoming increasingly implemented into mental health care and is expected to result in improved effectiveness and efficiency. To explore the feasibility of blended CBT for patients with a panic disorder. Nine face-to-face sessions of blended CBT (n = 18), supplemented with the digital support of a tabletcomputer and three e-mail contacts, were compared with 12 weekly sessions of regular CBT (n = 18). Primary outcomes were panic frequency and avoidance behaviour; the secondary outcome was general functioning. Patients' experiences of the treatment were collected in the form of a structured interview. The effect sizes found in both the regular and the blended CBT were medium to high (Cohen's d 0.42-1.60). In both types of treatment there was a significant reduction in patients' symptoms. There were no big differences in patient satisfaction regarding the treatment received. The therapists registered 39 face-to-face minutes in the blended treatment but they registered in total 41 fewer face-to-face minutes; this represented a time reduction of 4%. Blended CBT with help of a tablet computer seems to be a suitable method for treating panic disorder psychologically, although the time saved is only moderate. Much more research is needed to ascertain the feasibility and the cost effectiveness of blended CBT.

    Patients with head and neck cancer experience loss of weight and muscle mass, decreased functioning, malnutrition, depression, and declines in quality of life during and after treatment. The purpose of this exploratory randomized study was to determine the optimal timing for the initiation of a lifestyle and progressive resistance exercise training intervention (during or after radiation therapy), as determined by intervention adherence and by comparing between-group outcomes across 24 weeks. Sixty patients with head and neck cancer were randomized to engage in a 12-week lifestyle intervention and progressive resistance-training program either during radiation treatment or immediately after completion. The primary outcome of body composition--specifically, lean body mass, body mass index, and body fat--as well as secondary outcomes of fitness, quality of life, depression, and nutrition status were evaluated. The progressive resistance-training intervention carried out during treatment did not significantly influence the primary outcome of body composition, despite a significant increase in weekly physical activity reported by the intervention group. A small-to-medium intervention effect was noted for some secondary outcomes, including fitness, quality of life, and nutrition status. Regardless of whether patients received the immediate or delayed progressive resistance-training intervention, the analysis revealed a main effect of time on body composition, fitness, quality of life, depression, and nutritional scores. Although the intervention during treatment did not reduce the loss of lean body mass, delaying the exercise program until after treatment completion was associated with improved intervention adherence, a finding with important clinical implications. © 2016 American Cancer Society.

    The motesanib phase III MONET1 study failed to show improvement in overall survival (OS) in non-small cell lung cancer, but a subpopulation of Asian patients had a favorable outcome. We performed exploratory modeling and simulations based on MONET1 data to support further development of motesanib in Asian patients. A model-based estimate of time to tumor growth was the best of tested tumor size response metrics in a multivariate OS model (P Simulations indicated that a phase III study in 500 Asian patients would exceed 80% power to confirm superior efficacy of motesanib combination therapy (expected HR: 0.74), suggesting that motesanib combination therapy may benefit Asian patients.

    This exploratory, multicenter, open-label study evaluated the efficacy and safety of FTY720, as a part of an immunosuppressive regimen, in combination with everolimus and steroids in de novo renal transplant recipients at increased risk of delayed graft function (DGF). Patients received FTY720 (5 mg) and everolimus (4 mg) 2-12 h pre-transplantation, followed by 2.5 mg/d FTY720 and concentration-controlled everolimus (4-8 ng/mL) post-transplant for 12 months. Induction therapy was prohibited. After enrollment of 56 of the planned 200 patients between 2000 and 2002, the recruitment was terminated. The primary endpoint, rate of graft loss, or death at three months was 15.4% and the biopsy-confirmed acute rejection was 42.3%. Death or graft loss at 12 months in the DGF and non-DGF arms was 36.0% and 25.9%, respectively. The mean estimated creatinine clearance at three months was 63 and 55 mL/min in the non-DGF and DGF groups, respectively, while at 12 months it was 56 mL/min in both the groups. Although there was no comparator arm, the results from this exploratory study (compared with data from other phases II and III trials) indicated no apparent benefits of FTY720-based regimens for prevention of acute rejection and preservation of renal function in renal transplant recipients at high risk of DGF.

    The use of evidence-based practice (EBP) is encouraged in the physical therapy profession, but integrating evidence into practice can be difficult for clinicians because of lack of time and other constraints. To survey physical therapy clinical instructors and determine the methods they use for screening for deep vein thrombosis (DVT), a type of venous thromboembolism (VTE) in the lower extremities. Exploratory survey. Twelve survey questions written specifically for this study were sent to a convenience sample of clinical instructors associated with seven universities across 43 states. Eight hundred fifty clinical instructors (22.4% response rate) completed the survey. Of those who responded, 80.5% were taught to use Homans sign to screen for a possible DVT in their entry-level education and 67.9% continued to use Homans sign in clinical practice. Regardless of post-graduate education, respondents were more likely to choose Homans sign than a clinical decision rule (CDR) to screen for a suspected DVT. Additionally, nearly two-thirds of respondents failed to correctly identify one or more of the major risk factors for developing a DVT/VTE. The response rate was 22.4% and therefore may not fully represent the population of physical therapy clinical instructors in the United States. Results from this exploratory survey indicated that approximately two-thirds of physical therapy clinical instructors used outdated DVT/VTE screening methods that they were taught in their entry-level education and nearly two-thirds did not identify the major risk factors associated with DVT/VTE. These results suggest that change is necessary in physical therapy education, clinical practice, and continuing professional development to ensure a more evidenced-based identification of DVT and VTE.

    Full Text Available Abstract Background Mindfulness Based Cognitive Therapy (MBCT is an 8-week course developed for patients with relapsing depression that integrates mindfulness meditation practices and cognitive theory. Previous studies have demonstrated that non-depressed participants with a history of relapsing depression are protected from relapse by participating in the course. This exploratory study examined the acceptability and effectiveness of MBCT for patients in primary care with active symptoms of depression and anxiety Methods 13 patients with recurrent depression or recurrent depression and anxiety were recruited to take part in the study. Semi-structured qualitative interviews were conducted three months after completing the MBCT programme. A framework approach was used to analyse the data. Beck depression inventories (BDI-II and Beck anxiety inventories (BAI provided quantitative data and were administered before and three months after the intervention. Results The qualitative data indicated that mindfulness training was both acceptable and beneficial to the majority of patients. For many of the participants, being in a group was an important normalising and validating experience. However most of the group believed the course was too short and thought that some form of follow up was essential. More than half the patients continued to apply mindfulness techniques three months after the course had ended. A minority of patients continued to experience significant levels of psychological distress, particularly anxiety. Statistically significant reductions in mean depression and anxiety scores were observed; the mean pre-course depression score was 35.7 and post-course score was 17.8 (p = 0.001. A similar reduction was noted for anxiety with a mean pre-course anxiety score of 32.0 and mean post course score of 20.5 (p = 0.039. Overall 8/11 (72% patients showed improvements in BDI and 7/11 (63% patients showed improvements in BAI. In general the results

    The development of emergence agitation (EA) is associated with several factors including age, preoperative anxiety, postoperative pain, anesthesia method, and surgery type. No studies have investigated whether the withdrawal reaction following rocuronium injection can predict the occurrence of EA. Therefore, we investigated this relationship in preschool-aged children undergoing inguinal herniorrhaphy, and which grade of withdrawal reaction is appropriate for identifying patients at risk of experiencing EA. A total of 40 patients were enrolled in this study. During anesthesia induction, the withdrawal reaction after loss of consciousness following rocuronium injection was assessed using a 4-point scale. After surgery, EA was assessed using the Watcha scale. There was a correlation between withdrawal reaction and EA on admission to the postanesthesia care unit (PACU). Patients with a severe withdrawal reaction (grade 3) showed a significantly higher incidence of severe EA requiring medication on admission to the PACU. The findings of this preliminary exploratory observational study suggest that it is possible for withdrawal movement following rocuronium injection during anesthesia induction to reflect pain sensitivity of pediatric patients, which in turn may be useful in identifying those at risk of severe EA on admission to the PACU among preschool children undergoing inguinal herniorrhaphy. Further studies with a larger sample size are required to validate these findings. The exact correlation between pain reaction following rocuronium injection and postoperative pain or pain-related phenomenon should be elucidated.

    The Patient Health Questionnaire-9 (PHQ-9) is a widely used instrument for measuring levels of depression in patients in clinical practice and academic research; its factor structure has been investigated in various samples, with limited evidence of measurement equivalence/invariance (ME/I) but not in patients with more severe depression of long duration. This study aims to explore the factor structure of the PHQ-9 and the ME/I between treatment groups over time for these patients. 187 secondary care patients with persistent major depressive disorder (PMDD) were recruited to a randomised controlled trial (RCT) with allocation to either a specialist depression team arm or a general mental health arm; their PHQ-9 score was measured at baseline, 3, 6, 9 and 12 months. Exploratory Structural Equational Modelling (ESEM) was performed to examine the factor structure for this specific patient group. ME/I between treatment arm at and across follow-up time were further explored by means of multiple-group ESEM approach using the best-fitted factor structure. A two-factor structure was evidenced (somatic and affective factor). This two-factor structure had strong factorial invariance between the treatment groups at and across follow up times. Participants were largely white British in a RCT with 40% attrition potentially limiting the study's generalisability. Not all two-factor modelling criteria were met at every time-point. PHQ-9 has a two-factor structure for PMDD patients, with strong measurement invariance between treatment groups at and across follow-up time, demonstrating its validity for RCTs and prospective longitudinal studies in chronic moderate to severe depression.

    Synaptic loss is an early pathological finding in Alzheimer's disease (AD) and correlates with memory impairment. Changes in macroscopic brain activity measured with electro- and magnetoencephalography (EEG and MEG) in AD indicate synaptic changes and may therefore serve as markers of intervention effects in clinical trials. EEG peak frequency and functional networks have shown, in addition to improved memory performance, to be sensitive to detect an intervention effect in mild AD patients of the medical food Souvenaid containing the specific nutrient combination Fortasyn ® Connect, which is designed to enhance synapse formation and function. Here, we explore the value of MEG, with higher spatial resolution than EEG, in identifying intervention effects of the nutrient combination by comparing MEG spectral measures, functional connectivity, and networks between an intervention and a control group. Quantitative markers describing spectral properties, functional connectivity, and graph theoretical aspects of MEG from the exploratory 24-week, double-blind, randomized, controlled Souvenir II MEG sub-study (NTR1975, http://www.trialregister.nl) in drug naïve patients with mild AD were compared between a test group ( n  = 27), receiving Souvenaid, and a control group ( n  = 28), receiving an isocaloric control product. The groups were unbalanced at screening with respect to Mini-Mental State Examination. Peak frequencies of MEG were compared with EEG peak frequencies, recorded in the same patients at similar time points, were compared with respect to sensitivity to intervention effects. No consistent statistically significant intervention effects were detected. In addition, we found no difference in sensitivity between MEG and EEG peak frequency. This exploratory study could not unequivocally establish the value of MEG in detecting interventional effects on brain activity, possibly due to small sample size and unbalanced study groups. We found no indication that

    This study investigated the association of personality traits with the baseline clinical characteristics and treatment outcomes of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Subjects were evaluated at baseline and at week 12 following routine treatment for CP/CPPS using the Korean version of the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) to measure the severity of CP/CPPS; the Korean version of the Patient Health Questionnaire-9 (PHQ-9) to assess depression; the Korean version of the Patient Health Questionnaire-15 (PHQ-15) to evaluate somatization; and the Korean version of the EuroQol Questionnaire-5 Dimensions (EQ-5D), specifically the EQ-5D utility index and the EQ-5D visual analog scale (EQ-5D VAS), to assess quality of life (QoL). Personality traits including extraversion, agreeableness, conscientiousness, neuroticism, and openness were determined at baseline using the 44-item Big Five Inventory (BFI). The influence of personality traits on the clinical characteristics and treatment outcomes of patients with CP/CPPS was assessed using relevant statistical analyses. Neuroticism was associated with a significantly poorer treatment response and higher levels of depression and somatization. Extraversion, agreeableness, and conscientiousness had some influence on clinical characteristics but openness did not affect overall symptoms or the treatment response in patients with CP/CPPS. We found that neuroticism may be the most important personality trait associated with treatment response and the severity of depression and somatization in patients with CP/CPPS. However, our exploratory findings should be confirmed by additional studies with adequate power and improved designs. Copyright © 2013 Elsevier Inc. All rights reserved.

The mean time-lag between initial diagnosis and completion of the questionnaire was 89.7 months. The HRQOL significantly increased with the time-lag to surgery and decreased with the patients' age. Factors with clinically significant effects in several areas of long-term HRQOL (ie, more than 4 scores) were age, type of neck dissection, preoperative facial nerve palsy, and postoperative radiation therapy. In parotid gland cancer surgery, factors, such as sex, age, type of surgery, facial nerve palsy, and radiation therapy, seem to be associated with clinically meaningful differences in long-term HRQOL scores. © 2015 Wiley Periodicals, Inc.

    Full Text Available Abstract Background Comprehensive "Total Pain" assessments of patients' end-of-life needs are critical for providing improved patient-clinician communication, assessing needs, and offering high quality palliative care. However, patients' needs-based research methodologies and findings remain highly diverse with their lack of consensus preventing optimum needs assessments and care planning. Mixed-methods is an underused yet robust "patient-based" approach for reported lived experiences to map both the incidence and prevalence of what patients perceive as important end of life needs. Methods Findings often include methodological artifacts and their own selection bias. Moving beyond diverse findings therefore requires revisiting methodological choices. A mixed methods research cross-sectional design is therefore used to reduce limitations inherent in both qualitative and quantitative methodologies. Audio-taped phenomenological "thinking aloud" interviews of a purposive sample of 30 hospice patients are used to identify their vocabulary for communicating perceptions of end-of-life needs. Grounded theory procedures assisted by QSR-NVivo software is then used for discovering domains of needs embedded in the interview narratives. Summary findings are translated into quantified format for presentation and analytical purposes. Results Findings from this mixed-methods feasibility study indicate patients' narratives represent 7 core domains of end-of-life needs. These are (1 time, (2 social, (3 physiological, (4 death and dying, (5 safety, (6 spirituality, (7 change & adaptation. The prevalence, rather than just the occurrence, of patients' reported needs provides further insight into their relative importance. Conclusion Patients' perceptions of end-of-life needs are multidimensional, often ambiguous and uncertain. Mixed methodology appears to hold considerable promise for unpacking both the occurrence and prevalence of cognitive structures represented by

No studies have investigated whether the withdrawal reaction following rocuronium injection can predict the occurrence of EA. Therefore, we investigated this relationship in preschool-aged children undergoing inguinal herniorrhaphy, and which grade of withdrawal reaction is appropriate for identifying patients at risk of experiencing EA. Methods: A total of 40 patients were enrolled in this study. During anesthesia induction, the withdrawal reaction after loss of consciousness following rocuronium injection was assessed using a 4-point scale. After surgery, EA was assessed using the Watcha scale. Results: There was a correlation between withdrawal reaction and EA on admission to the postanesthesia care unit (PACU. Patients with a severe withdrawal reaction (grade 3 showed a significantly higher incidence of severe EA requiring medication on admission to the PACU. Conclusion: The findings of this preliminary exploratory observational study suggest that it is possible for withdrawal movement following rocuronium injection during anesthesia induction to reflect pain sensitivity of pediatric patients, which in turn may be useful in identifying those at risk of severe EA on admission to the PACU among preschool children undergoing inguinal herniorrhaphy. Further studies with a larger sample size are required to validate these findings. The exact correlation between pain

    In Malaysia, compulsory drug detention centres (CDDCs) hold suspected drug users for two years without adjudication. Acute detoxification without healthcare access has been documented. CDDCs are criticized globally due to ineffectiveness in treating addiction and human rights violations. In response, the Malaysian government began transitioning these facilities into voluntary drug treatment centres known as "Cure and Care" (C&C) centres that embrace a holistic treatment-based approach to drug addiction rehabilitation. An explorative qualitative study was undertaken to explore patient perspectives and satisfaction regarding treatment and services at the new Cure and Care centre in Kota Bharu, Malaysia. A convenience sample of 20 patients was recruited to participate in semi-structured in-depth interviews. Content analysis was used to identify the salient themes. Patients identified methadone treatment, psychosocial programs, religious instruction, and recreational activities as important factors contributing to treatment success for addressing both health and addiction needs. Though many had previously been in a CDDC, adherence to treatment in the C&C centre was perceived to be facilitated by the degree of social support, the voluntary nature and the array of new programs available for selection. C&Cs represents a dramatic shift in the Malaysian government's approach to drug addiction. Our findings demonstrate positive patient experiences associated with the holistic treatment-based approach of these centres. This exploratory study provides additional evidence to document this ongoing policy transition and may guide continued expansion of new holistic drug treatment programs across the country.

    Research on patient safety in allied healthcare is scarce. Our aim was to document patient safety in primary allied healthcare in the Netherlands and to identify factors associated with incidents. DESIGN AND SUBJECT: A retrospective study of 1000 patient records in a representative sample of 20 allied healthcare practices was combined with a prospective incident-reporting study. All records were reviewed by trained researchers to identify patient safety incidents. The incidents were classified and analyzed, using the Prevention and Recovery Information System for Monitoring and Analysis method. Factors associated with incidents were examined in a logistic regression analysis. In 18 out of 1000 (1.8%; 95% confidence interval: 1.0-2.6) records an incident was detected. The main causes of incidents were related to errors in clinical decisions (89%), communication with other healthcare providers (67%), and monitoring (56%). The probability of incidents was higher if more care providers had been involved and if patient records were incomplete (37% of the records). No incidents were reported in the prospective study. The absolute number of incidents was low, which could imply a low risk of harm in Dutch primary allied healthcare. Nevertheless, incompleteness of the patient records and the fact that incidents were mainly caused through human actions suggest that a focus on clinical reasoning and record keeping is needed to further enhance patient safety. Improvements in record keeping will be necessary before accurate incident reporting will be feasible and valid.

    Background: Biomarkers predicting the risk of VL treatment failure and relapse in VL/HIV coinfected patients are needed. Nested within a two-site clinical trial in Ethiopia (2011-2015), we conducted an exploratory study to assess whether (1) levels of Leishmania antigenuria measured at VL diagnosis were associated with initial treatment failure and (2) levels of Leishmania antigenuria at the end of treatment (parasitologically-confirmed cure) were associated with subsequent relapse. Methods: Leishmania antigenuria at VL diagnosis and cure was determined using KAtex urine antigen test and graded as negative (0), weak/moderate (grade 1+/2+) or strongly-positive (3+). Logistic regression and Kaplan-Meier methods were used to assess the association between antigenuria and (1) initial treatment failure, and (2) relapse over the 12 months after cure, respectively. Results: The analysis to predict initial treatment failure included sixty-three coinfected adults [median age: 30 years interquartile range (IQR) 27-35], median CD4 count: 56 cells/μL (IQR 38-113). KAtex results at VL diagnosis were negative in 11 (17%), weak/moderate in 17 (27%) and strongly-positive in 35 (36%). Twenty (32%) patients had parasitologically-confirmed treatment failure, with a risk of failure of 9% (1/11) with KAtex-negative results, 0% (0/17) for KAtex 1+/2+ and 54% (19/35) for KAtex 3+ results. Compared to KAtex-negative patients, KAtex 3+ patients were at increased risk of treatment failure [odds ratio 11.9 (95% CI 1.4-103.0); P : 0.025]. Forty-four patients were included in the analysis to predict relapse [median age: 31 years (IQR 28-35), median CD4 count: 116 cells/μL (IQR 95-181)]. When achieving VL cure, KAtex results were negative in 19 (43%), weak/moderate (1+/2+) in 10 (23%), and strongly positive (3+) in 15 patients (34%). Over the subsequent 12 months, eight out of 44 patients (18%) relapsed. The predicted 1-year relapse risk was 6% for KAtex-negative results, 14% for KAtex 1

    Lynch syndrome is an inherited syndrome with the development of the colorectal and various other cancers. Lynch syndrome is caused by mutations in the mismatch repair genes. A 33 year-old male underwent XELOX adjuvant chemotherapy for ascending colon cancer with Lynch syndrome. Although efficacy of 5-FU is not demonstrated in Lynch syndrome, MOSAIC trial had suggested a benefit from FOLFOX compared with 5-FU in patients who have colorectal cancer with Lynch syndrome. Oxaliplatin-based adjuvant chemotherapy can be a therapeutic option for colorectal cancer in lynch syndrome patients.

    More than half of the patients selected based on KRAS mutation status fail to respond to the treatment with cetuximab in metastatic colorectal cancer (mCRC). We designed a study to identify additional biomarkers that could act as indicators for cetuximab treatment in mCRC. We investigated 58 tumor samples from wild type KRAS CRC patients treated with cetuximab plus irinotecan (CI). We conducted the genotyping for mutations in either BRAF or PIK3CA and profiled comprehensively the expression of 522 kinase genes. BRAF mutation was detected in 5.1 % (3/58) of patients. All 50 patients showed wild type PIK3CA. Gene expression patterns that categorized patients with or without the disease control to CI were compared by supervised classification analysis. PSKH1, TLK2 and PHKG2 were overexpressed significantly in patients with the disease control to IC. The higher expression value of PSKH1 (r = 0.462, p < 0.001) and TLK2 (r = 0.361, p = 0.005) had the significant correlation to prolonged PFS. The result of this work demonstrated that expression nature of kinase genes such as PSKH1, TLK2 and PHKG2 may be informative to predict the efficacy of CI in wild type KRAS CRC. Mutations in either BRAF or PIK3CA were rare subsets in wild type KRAS CRC

    The etiology of mental illness has been attributed to many different causes by people of various cultural backgrounds, including supernatural beliefs. This in turn affects the help-seeking behavior. Aim of this study was to explore the supernatural belief and pathways of care in patients with obsessive compulsive disorder (OCD) attending a tertiary care hospital located in north India. In all, 89 consecutive patients diagnosed with OCD (according to the International Classification of Diseases-10th Revision (ICD-10)) and ≥ 15 years of age were evaluated for their supernatural belief and help seeking. More than half of the patients (54%) believed in supernatural causes and 57.3% attributed their illness to supernatural causes. In addition to supernatural causes, many patients also attributed their illness to stress (household/work-related stress) or chemical imbalance in the body and or mind. About two-thirds of the patients (n = 58; 65.2%) first contacted a psychiatrist for their symptoms of OCD. Those who first contacted faith healers believed in one of the supernatural causations. Patients with OCD hold multiple beliefs regarding the etiology and treatment of mental illness which can affect their pathways to care. © The Author(s) 2014.

    Both binge eating disorder (BED) and pathological gambling (PG) are characterized by impairments in impulse control. Subsyndromal levels of PG have been associated with measures of adverse health. The nature and significance of PG features in individuals with BED is unknown. Ninety-four patients with BED (28 men and 66 women) were classified by gambling group based on inclusionary criteria for Diagnostic and Statistical Manual-IV (DSM-IV) PG and compared on a range of behavioral, psychological and eating disorder (ED) psychopathology variables. One individual (1.1% of the sample) met criteria for PG, although 18.7% of patients with BED displayed one or more DSM-IV criteria for PG, hereafter referred to as problem gambling features. Men were more likely than women to have problem gambling features. BED patients with problem gambling features were distinguished by lower self-esteem and greater substance problem use. After controlling for gender, findings of reduced self-esteem and increased substance problem use among patients with problem gambling features remained significant. In patients with BED, problem gambling features are associated with a number of heightened clinical problems.

    Acute skin toxicity is one of the most common side effects of breast cancer radiotherapy. To date, no one has estimated the nonmedical out-of-pocket expenses associated with this side effect. The primary aim of the present descriptive, exploratory study was to assess the feasibility of a newly developed skin toxicity costs questionnaire. The secondary aims were to: (1) estimate nonmedical out-of-pocket costs, (2) examine the nature of the costs, (3) explore potential background predictors of costs, and (4) explore the relationship between patient-reported dermatologic quality of life and expenditures. A total of 50 patients (mean age = 54.88, Stage 0-III) undergoing external beam radiotherapy completed a demographics/medical history questionnaire as well as a seven-item Skin Toxicity Costs (STC) questionnaire and the Skindex-16 in week 5 of treatment. Mean skin toxicity costs were $131.64 (standard error [SE] = $23.68). Most frequently incurred expenditures were new undergarments and products to manage toxicity. Education was a significant unique predictor of spending, with more educated women spending more money. Greater functioning impairment was associated with greater costs. The STC proved to be a practical, brief measure which successfully indicated specific areas of patient expenditures and need. Results reveal the nonmedical, out-of-pocket costs associated with acute skin toxicity in the context of breast cancer radiotherapy. To our knowledge, this study is the first to quantify individual costs associated with this treatment side effect, as well as the first to present a scale specifically designed to assess such costs. In future research, the STC could be used as an outcome variable in skin toxicity prevention and control research, as a behavioral indicator of symptom burden, or as part of a needs assessment.

    Burns are physically, psychologically and economically challenging injuries, and the factors leading to them are many and under-studied. The aim of the current study was to assess level of anxiety, depression and self-esteem in burn patients, and look at various burn-related variables that affect them. This cross-sectional study included 100 patients with burn injuries admitted to a tertiary care private hospital in an urban metropolis in India. The patients were assessed for anxiety, depression and self-esteem using the Hamilton anxiety rating scale, Hamilton depression rating scale and Rosenberg self-esteem scale respectively. Assessment was carried out within 2-8 weeks of injury following medical stabilization. The data was tabulated and statistically analyzed. The study sample was predominantly male (54%), married (69%), with a mean age of 34.1 ± 10.8 years. Accidental burns (94%) were the most common modality of injury. The majority (46%) suffered burns involving 20-59% total body surface area (TBSA), and facial burns were present (57%). No significant association was found between TBSA and anxiety, depression or self-esteem, and the same was true for facial burns. Deep burns, however, were significantly associated with anxiety (p=0.03) and depression (p=0.0002). High rates of anxiety and depression are associated with burn injuries and related to burn depth. Adjustment and recovery in these patients depends on various other factors like the patient's psychological status, nature/extent of the injury and ensuing medical care. Further research is warranted to reveal the magnitude and predictors of psychological problems in burn patients.

    Background and aims Despite the high prevalence of knee osteoarthritis (OA) it remains one of the most frequent knee disorders without a cure. Pain and disability are prominent clinical features of knee OA. Knee OA pain is typically localized but can also be referred to the thigh or lower leg. Widespread hyperalgesia has been found in knee OA patients. In addition, patients with hyperalgesia in the OA knee joint show increased pain summation scores upon repetitive stimulation of the OA knee suggesting the involvement of facilitated central mechanisms in knee OA. The dynamics of the pain system (i.e., the adaptive responses to pain) has been widely studied, but mainly from experiments on healthy subjects, whereas less is known about the dynamics of the pain system in chronic pain patients, where the pain system has been activated for a long time. The aim of this study was to assess the dynamics of the nociceptive system quantitatively in knee osteoarthritis (OA) patients before and after induction of experimental knee pain. Methods Ten knee osteoarthritis (OA) patients participated in this randomized crossover trial. Each subject was tested on two days separated by 1 week. The most affected knee was exposed to experimental pain or control, in a randomized sequence, by injection of hypertonic saline into the infrapatellar fat pad and a control injection of isotonic saline. Pain areas were assessed by drawings on anatomical maps. Pressure pain thresholds (PPT) at the knee, thigh, lower leg, and arm were assessed before, during, and after the experimental pain and control conditions. Likewise, temporal summation of pressure pain on the knee, thigh and lower leg muscles was assessed. Results Experimental knee pain decreased the PPTs at the knee (P system in individuals with knee OA can be affected even after many years of nociceptive input. This study indicates that the adaptability in the pain system is intact in patients with knee OA, which opens for opportunities to

    For many eServices, end-user trust is a crucial prerequisite for use. Within the context of Telemedicine, the role of trust has hardly ever been studied. In this study, we explored what determines trust in portals that facilitate rehabilitation therapy, both from the perspective of the patient and the healthcare professional. We held two focus groups with patients (total n = 15) and two with healthcare professionals (total n = 13) in which we discussed when trust matters, what makes up trust in a rehabilitation portal, what effect specific design cues have, and how much the participants trust the use of activity sensor data for informing treatment. Trust in a rehabilitation portal is the sum of trust in different factors. These factors and what makes up these factors differ for patients and healthcare professionals. For example, trust in technology is made up, for patients, mostly by a perceived level of control and privacy, while for healthcare professionals, a larger and different set of issues play a role, including technical reliability and a transparent data storage policy. Healthcare professionals distrust activity sensor data for informing patient treatment, as they think that sensors are unable to record the whole range of movements that patients make (e.g., walking and ironing clothes). The set of factors that affect trust in a rehabilitation portal are different from the sets that have been found for other contexts, like eCommerce. Trust in telemedicine technology should be studied as a separate subject to inform the design of reliable interventions.

    The provision of the patient bed-bath is a fundamental nursing care activity yet few quantitative data and no qualitative data are available on registered nurses' (RNs) clinical practice in this domain in the intensive care unit (ICU). The aim of this study was to describe ICU RNs current practice with respect to the timing, frequency and duration of the patient bed-bath and the cleansing and emollient agents used. The study utilised a two-phase sequential explanatory mixed method design. Phase one used a questionnaire to survey RNs and phase two employed semi-structured focus group (FG) interviews with RNs. Data was collected over 28 days across four Australian metropolitan ICUs. Ethical approval was granted from the relevant hospital and university human research ethics committees. RNs were asked to complete a questionnaire following each episode of care (i.e. bed-bath) and then to attend one of three FG interviews: RNs with less than 2 years ICU experience; RNs with 2-5 years ICU experience; and RNs with greater than 5 years ICU experience. During the 28-day study period the four ICUs had 77.25 beds open. In phase one a total of 539 questionnaires were returned, representing 30.5% of episodes of patient bed-baths (based on 1767 bed occupancy and one bed-bath per patient per day). In 349 bed-bath episodes 54.7% patients were mechanically ventilated. The bed-bath was given between 02.00 and 06.00h in 161 episodes (30%), took 15-30min to complete (n=195, 36.2%) and was completed within the last 8h in 304 episodes (56.8%). Cleansing agents used were predominantly pH balanced soap or liquid soap and water (n=379, 71%) in comparison to chlorhexidine impregnated sponges/cloths (n=86, 16.1%) or other agents such as pre-packaged washcloths (n=65, 12.2%). In 347 episodes (64.4%) emollients were not applied after the bed-bath. In phase two 12 FGs were conducted (three FGs at each ICU) with a total of 42 RN participants.

    Depressive symptoms cause major impairment and may accelerate HIV progression despite the use of antiretroviral medication. The somatic symptoms criteria for HIV infection and depression partially overlap, which can make differential diagnosis challenging. Because of chronic inflammation caused by HIV infection, HIV-positive patients may develop somatic and affective-cognitive symptoms of depression. Inflammation-related depression is primarily characterized with severe somatic symptoms such as fatigue and sleep disturbance. This study sought to explore the patterns of somatic and cognitive-affective depressive symptoms that characterize HIV-positive patients. Our specific aims were (1) to identify subtypes of depressive symptoms in a sample of HIV-positive patients; and (2) to test the subtypes' difference on inflammatory and HIV disease progression biomarkers. HIV-positive men and women (N=102) with and without depressive symptoms were randomly selected from an Italian HIV clinic. Depressive symptoms (PHQ-9), viral load (VL), CD4+, Il-6, TNF-α, and monocytes were assessed. The three subtypes formed using Latent Class Analysis (LCA) identified patients with (1) severe cognitive-affective and somatic depressive symptoms; (2) severe/moderate somatic symptoms; and (3) absent or low depressive symptoms. The subtype with severe/moderate somatic symptoms was characterized with elevated levels of Il-6 and monocytes. No difference on HIV progression biomarkers was found. The subtypes of depressive symptoms might help differentiating depressive symptoms from HIV- and inflammatory-related somatic symptoms. When present, cognitive-affective and/or somatic symptoms cause significant impairment to patients' lives and thus warrant further assessment and treatment. Copyright © 2016 Elsevier Inc.

    INTRODUCTION Treatment of gout, specifically with colchicine, varies globally. Colchicine can be fatal due to its narrow therapeutic index and potential for interactions. In New Zealand, cases of intentional and unintentional colchicine overdose have been documented. AIMS To explore patients' knowledge on the use of gout medicines, and in particular their awareness of the maximum dose of colchicine, the dangers of colchicine overdose, and their opinions on restricting colchicine dispensing. The study also investigates where patients receive gout information. METHODS Thirty people with gout presenting to their regular gout clinic in Auckland currently or previously taking colchicine were invited to participate in a 30-min semi-structured interview. Data were analysed using a general inductive thematic approach. FINDINGS Overall, participants had a lack of knowledge regarding colchicine and used variable doses during an acute gout attack. Participants were unsure of the maximum dose of colchicine and several took more than prescribed. The prophylactic use of colchicine and allopurinol varied from 3 weeks to 15 years. Mixed views were reported on restricting colchicine supply. Most participants received gout information from their general practitioner (GP). CONCLUSION Poor understanding of colchicine contributed to inappropriate use and highlights the need for targeted patient education. Considerable inter-patient variability exists in the use of colchicine for acute gout, suggesting the efficacy of low dose regimens be explored. The length of adjunctive colchicine use, as part of a prophylaxis regimen, needs to be regularly reviewed and tailored to each patient. Further research is required on limiting the amount of colchicine dispensed.

    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

    Full Text Available Abstract Background Little research has been done on patient call light use and staff response time, which were found to be associated with inpatient falls and satisfaction. Nurses' perspectives may moderate or mediate the aforementioned relationships. This exploratory study intended to understand staff's perspectives about call lights, staff responsiveness, and the reasons for and the nature of call light use. It also explored differences among hospitals and identified significant predictors of the nature of call light use. Methods This cross-sectional, multihospital survey study was conducted from September 2008 to January 2009 in four hospitals located in the Midwestern region of the United States. A brief survey was used. All 2309 licensed and unlicensed nursing staff members who provide direct patient care in 27 adult care units were invited to participate. A total of 808 completed surveys were retrieved for an overall response rate of 35%. The SPSS 16.0 Window version was used. Descriptive and binary logistic regression analyses were conducted. Results The primary reasons for patient-initiated calls were for toileting assistance, pain medication, and intravenous problems. Toileting assistance was the leading reason. Each staff responded to 6 to 7 calls per hour and a call was answered within 4 minutes (estimated. 49% of staff perceived that patient-initiated calls mattered to patient safety. 77% agreed that that these calls were meaningful. 52% thought that these calls required the attention of nursing staff. 53% thought that answering calls prevented them from doing the critical aspects of their role. Staff's perceptions about the nature of calls varied across hospitals. Junior staff tended to overlook the importance of answering calls. A nurse participant tended to perceive calls as more likely requiring nursing staff's attention than a nurse aide participant. Conclusions If answering calls was a high priority among nursing tasks, staff

    Tinnitus is the perception of sound in the absence of a corresponding external acoustic stimulus. Bimodal neuromodulation is emerging as a promising treatment for this condition. The main objectives of this study are to investigate the relevance of interstimulus timing and the choices of acoustic and tongue stimuli for a proprietary bimodal (auditory and somatosensory) neuromodulation device, as well as to explore whether specific subtypes of patients are differentially responsive to this novel intervention for reducing the symptoms of chronic tinnitus. This is a two-site, randomised, triple-blind, exploratory study of a proprietary neuromodulation device with a pre-post and 12-month follow-up design. Three different bimodal stimulation parameter sets will be examined. The study will enrol 342 patients, split 80:20 between two sites (Dublin, Ireland and Regensburg, Germany), to complete 12 weeks of treatment with the device. Patients will be allocated to one of three arms using a stepwise stratification according to four binary categories: tinnitus tonality, sound level tolerance (using loudness discomfort level of Tinnitus Handicap Inventory and the Tinnitus Functional Index, after 12 weeks of intervention. Clinical efficacy will be further explored in a series of patient subtypes, split by the stratification variables and by presence of a somatic tinnitus. Evidence for sustained effects on the psychological and functional impact of tinnitus will be followed up for 12 months. Safety data will be collected and reported. A number of feasibility measures to inform future trial design include: reasons for exclusion, completeness of data collection, attrition rates, patient's adherence to the device usage as per manufacturer's instructions and evaluation of alternative methods for estimating tinnitus impact and tinnitus loudness. This study protocol is approved by the Tallaght Hospital/St. James's Hospital Joint Research Ethics Committee in Dublin, Ireland, and by the

    Vestibular rehabilitation is useful to alleviate chronic dizziness in patients with vestibular dysfunction. It aims to induce neuronal plasticity in the central nervous system (especially in the cerebellum) to promote vestibular compensation. Transcranial cerebellar direct current stimulation (tcDCS) reportedly enhances cerebellar function. We investigated whether vestibular rehabilitation partially combined with tcDCS is superior to the use of rehabilitation alone for the alleviation of dizziness. Patients with chronic dizziness due to vestibular dysfunction received rehabilitation concurrently with either 20-min tcDCS or sham stimulation for 5 days. Pre- and post-intervention (at 1 month) dizziness handicap inventory (DHI) scores and psychometric and motor parameters were compared. Sixteen patients completed the study. DHI scores in the tcDCS group showed significant improvement over those in the sham group (Mann-Whitney U test, p = 0.033). Vestibular rehabilitation partially combined with tcDCS appears to be a promising approach. Copyright © 2017 Elsevier Inc. All rights reserved.

    Although 'irrational' decision-making has been linked to depression, the contribution of biases in information processing to these findings remains unknown. To investigate the impact of cognitive biases and aberrant processing of facial emotions on social decision-making, we manipulated both context-related and emotion-related information in a modified Ultimatum Game. Unfair offers were (1) paired with different unselected alternatives, establishing the context in which an offer was made, and (2) accompanied by emotional facial expressions of proposers. Responder behavior was assessed in patients with major depressive disorder and healthy controls. In both groups alike, rejection rates were highest following unambiguous signals of unfairness, i.e. an angry proposer face or when an unfair distribution had deliberately been chosen over an equal split. However, depressed patients showed overall higher rejection rates than healthy volunteers, without exhibiting differential processing biases. This suggests that depressed patients were, as healthy individuals, basing their decisions on informative, salient features and differentiating between (i) fair and unfair offers, (ii) alternatives to unfair offers and (iii) proposers' facial emotions. Although more fundamental processes, e.g. reduced reward sensitivity, might underlie increased rejection in depression, the current study provides insight into mechanisms that shape fairness considerations in both depressed and healthy individuals. © 2013 Elsevier Ireland Ltd.

    The human esophageal mucosa expresses various components of the renin-angiotensin system (RAS), e.g. the main effector peptide angiotensin II (AngII). The aim of this study was to investigate the esophageal presence of angiotensin III (AngIII) and angiotensin IV (AngIV) forming enzymes and the AngIV receptor (AT4R). The aim was also to study the actions of AngIV and to look for aberrations in patients with gastroesophageal reflux disease (GERD). Esophageal biopsies were collected from healthy volunteers (n: 19) and individuals with erosive reflux disease (n: 14). Gene transcripts and protein expression of aminopeptidase A, -B and -M, and the AT4R were investigated by reverse transcriptase polymerase chain reaction (rt-PCR), western blot (WB) and immunohistochemistry (IHC). The functional impact of AngIV was examined in an Ussing chamber. Aminopeptidase A, -B and -M and the AT4R were expressed in the esophageal epithelium. The AT4R was less prominent in certain areas in the mucosa of reflux patients. AngIV influenced the esophageal epithelial ion transport. The impact was lower in patients with GERD. The AT4R and formation enzymes of AngIII and AngIV are present in the human esophageal epithelium. Moreover, the present results suggest that AngIV exert regulatory impact on the epithelium and that RAS is involved in mucosal aberrations associated with GERD. © The Author(s) 2014.

    The lives of African American men with prostate cancer are greatly influenced by the information available to them, some of which is accessed on the Internet. Research indicates that the Internet can enhance consumer health knowledge but has not reached socioeconomic groups at highest risk for health disparities, such as African American men with prostate cancer. In this study, focus groups were used to explore the perceptions and uses of the Internet as a patient education tool among 39 African American men aged 39 years and older with diverse socioeconomic backgrounds. Nineteen (49%) participants reported using the Internet, 15 (38%) reported no use but indicated it was used on their behalf, and 5 (13%) reported no use and no use on their behalf. The findings revealed varying degrees of Internet use for information and social support. Prostate cancer diagnosis, poor patient-doctor communications, and accessibility influenced Internet use. Accessibility related more to lack of ease and familiarity with Internet use than lack of computer access. With training and awareness, the Internet has potential as a patient education tool among African American men with prostate cancer.

    The aim of the present study was to evaluate the association between illness perceptions and the ability to cope with physical and mental health problems in a large cohort of systemic sclerosis (SSc) patients. This was a cross-sectional study in 217 systemic sclerosis patients from the Belgian Systemic Sclerosis Cohort. Illness perception and coping were measured by the Revised Illness Perception Questionnaire and a coping questionnaire--the Coping Orientation of Problem Experience inventory (COPE). Physical and mental health-related quality of life was measured by the 36-item short-form health survey (SF-36), as were disease activity and several severity parameters. The relationship between illness perceptions and the ability to cope with physical/mental health problems was examined using multiple linear regression analysis. According to LeRoy's classification, 49 patients had limited SSc (lSSc), 129 had limited cutaneous SSc (lcSSc) and 39 had diffuse cutaneous SSc (dcSSc). Median disease duration was five years and the modified Rodnan skin score was 4.

    The objectives of the study were to evaluate the possibility of reflexology being used as a non-invasive form of phantom limb pain relief and of empowering patients to maintain any positive results with self-treatment. Prosthetic Services Centre, Herbert Street, Wolverhampton, West Midlands, England. A same-subject, experimental pilot study, recording the intensity of phantom limb pain in weekly pain diaries over a 30-week period, which was divided into five phases: phase 1 gave a baseline of pain, whilst phase 3 was a resting phase. Phases 2, 4 and 5 provided the reflexology interventions. Ten participants with unilateral lower limb amputations and phantom limb pain were selected from the database at the Prosthetic Centre. REFLEXOLOGY INTERVENTIONS: In phase 2, six weekly reflexology treatments were given, which consisted of: full foot reflexology to the remaining foot and full hand reflexology to the hand of the amputated side of the body. In phase 4, six weekly hand reflexology teaching sessions were carried out; patients copied on their own hands what the therapist did on hers. A hand reflexology booklet gave the sequence of the treatment and was used as a reference. In phase 5, the patients self-treated for 6 weeks at home, using the reference material. Over the 30-week period, there was an improvement in the perception of the presence and the intensity of the phantom limb pain, with a corresponding improvement in the duration of the pain and the affect on the person's lifestyle. The improvement was maintained when the clients self-treated. FOLLOW-UP QUESTIONNAIRE: A follow-up questionnaire was carried out in 2007--12 months after the project had ended--to elicit whether the patients had suffered from phantom pain over the previous 12 months, whether they still had relief from phantom limb pain and whether they still self-treated. The project indicated that reflexology treatment, teaching and self-treatment were effective in eradicating or reducing the

    To undertake a cost-consequence analysis to assess two new models of partner notification (PN), known as Accelerated Partner Therapy (APT Hotline and APT Pharmacy), as compared with routine patient referral PN, for sex partners of people with chlamydia, gonorrhoea and non-gonococcal urethritis. Comparison of costs and outcomes alongside an exploratory trial involving two genitourinary medicine clinics and six community pharmacies. Index patients selected the PN method (APT Hotline, APT Pharmacy or routine PN) for their partners. Clinics and pharmacies recorded cost and resource use data including duration of consultation and uptake of treatment pack. Cost data were collected prospectively for two out of three interventions, and data were synthesised and compared in terms of effectiveness and costs. Routine PN had the lowest average cost per partner treated (approximately £46) compared with either APT Hotline (approximately £54) or APT Pharmacy (approximately £53) strategies. The cost-consequence analysis revealed that APT strategies were more costly but also more effective at treating partners compared to routine PN. The hotline strategy costs more than both the alternative PN strategies. If we accept that strategies which identify and treat partners the fastest are likely to be the most effective in reducing reinfection and onward transmission, then APT Hotline appears an effective PN strategy by treating the highest number of partners in the shortest duration. Whether the additional benefit is worth the additional cost cannot be determined in this preliminary analysis. These data will be useful for informing development of future randomised controlled trials of APT.

    Full Text Available Abstract Background Carotid plaque rupture, characterized by ruptured fibrous cap (FC, is associated with subsequent cerebrovascular events. However, ruptured FC may heal following stroke and convey decreased risk of future events. This study aims to characterize the healing process of ruptured FC by assessing the lumen conditions, quantified by the lumen curvature and roughness, using in vivo carotid cardiovascular magnetic resonance (CMR. Methods Patients suffering from transient ischemic attack underwent high resolution carotid MR imaging within 72 hours of the acute cerebrovascular ischemic event. CMR imaging was repeated at 3 and 12 months in 26 patients, in whom FC rupture/erosion was observed on baseline images and subsequent cerebrovascular events were recorded during the follow-up period. Lumen curvature and roughness were quantified from carotid CMR images and changes in these values were monitored on follow-up imaging. Results Healing of ruptured plaque was observed in patients (23 out of 26 without any ischemic symptom recurrence as shown by the lumen surface becoming smoother during the follow-up period, characterized by decreasing maximum lumen curvature (p Conclusions Carotid plaque healing can be assessed by quantification of the lumen curvature and roughness and the incidence of recurrent cerebrovascular events may be high in plaques that do not heal with time. The assessment of plaque healing may facilitate risk stratification of recent stroke patients on the basis of CMR results.

    The effect of music therapy on anger management and coping skills is an innovative subject in the field of forensic psychiatry. This study explores the following research question: Can music therapy treatment contribute to positive changes in coping skills, anger management, and dysfunctional behavior of forensic psychiatric patients? To investigate this question, first a literature review is offered on music therapy and anger management in forensic psychiatry. Then, an explorative study is presented. In the study, a pre- and post-test design was used with a random assignment of patients to either treatment or control condition. Fourteen participants' complete datasets were collected. All participants received "treatment as usual." Nine of the participants received a standardized, music therapy anger management program; the five controls received, unplanned, an aggression management program. Results suggested that anger management skills improved for all participants. The improvement of positive coping skills and diminishing of avoidance as a coping skill were measured to show greater changes in music therapy participants. When controlling for the exact number of treatment hours, the outcomes suggested that music therapy might accelerate the process of behavioral changes. © The Author(s) 2013.

    Out of 134 patients irradiated below the diaphragm to a dose of 40 Gy for Hodgkin's disease at the Institut Gustave-Roussy, 19 (14%) were subsequently found to present with radiation injuries of the gastrointestinal tract. Since five patients presented with two different injuries, 24 radiolesions were observed. Most of them (17 out of 24) were gastric or duodenal. Twelve (out of 24) were ulcers. Nine patients required surgery. A complete cure of the radiation injuries was obtained in 15 out of 19 patients. Sex, age, stage, histology or initial chemotherapy were not found to play a role in the occurrence of radiation damage. On the contrary, the role of a previous exploratory laparotomy appeared important; for the patients who underwent laparotomy and irradiation, the complication rate was 23%. For the patients treated by irradiation alone, the complication rate was 7% (p < 0.01). Fractionation was found to be another important parameter: for 52 patients treated using 3 weekly fractions of 3.3 Gy, the complication rate was 25% compared to 8% (p < 0.01) for 76 patients treated using 4 weekly fractions of 2.5 Gy. Combining these two factors, the authors found a 42% complication rate for the group of patients who underwent laparotomy and who were treated by means of 3 fractions of 3.3 Gy per week, whereas patients irradiated using 4 weekly fractions of 2.5 Gy, without any previous laparotomy, has only a 5% complication risk (p < 0.001).

RESULTS: Epo reduced neural response to negative vs. positive pictures 3 days post-administration in a network of areas including the hippocampus, ventromedial...... prefrontal and parietal cortex. After the scan, Epo-treated patients showed improved memory compared with those that were given placebo. The effects occurred in the absence of changes in mood or haematological parameters, suggesting that they originated from direct neurobiological actions of Epo. CONCLUSIONS......: These findings are similar to the effects of conventional antidepressants and opposite to the negative biases in depression. The central effects of Epo therefore deserve further investigation as a potential antidepressant mechanism....

    To determine whether increases in adolescent or parental self-efficacy predicted subsequent weight gain in two different therapies for adolescent anorexia nervosa (AN). Participants were 121 adolescents with AN (M = 14.4 years, SD = 1.6), from a two-site randomized clinical trial for family-based treatment (FBT) and individual adolescent focused therapy (AFT). Both adolescent and parental self-efficacy were assessed at baseline and sessions 2, 4, 6, and 8. Adolescent self-efficacy was assessed using a generic measure of self-efficacy, while parental self-efficacy was assessed using a measure specific to the recovery of an eating disorder. Weight was assessed at baseline, sessions 1 through 8, and end of treatment. Mixed-effects models were used to evaluate the relation between patient and parent self-efficacy and subsequent weight gain, controlling for weight at the previous time point. For families who received FBT, greater within-treatment increases in parental self-efficacy predicted greater subsequent adolescent weight gain compared to those who received FBT with lesser change in parental self-efficacy and those who received AFT. Interestingly, adolescent self-efficacy did not significantly predict subsequent weight gain. Greater increases in parental self-efficacy predicted significantly greater subsequent weight gain for adolescents who received FBT, but the same was not true for adolescents who received AFT. Neither overall level nor change in adolescent self-efficacy significantly predicted subsequent weight gain in either treatment group. These findings emphasize the importance of increasing parental self-efficacy in FBT in order to impact adolescent weight outcomes. © 2015 Wiley Periodicals, Inc.

  14. Intraoperative hemidiaphragm electrical stimulation reduces oxidative stress and upregulates autophagy in surgery patients undergoing mechanical ventilation: exploratory study

    Full Text Available Abstract Background Mechanical ventilation (MV during a cardio-thoracic surgery contributes to diaphragm muscle dysfunction that impairs weaning and can lead to the ventilator- induced diaphragm dysfunction. Especially, it is critical in older adults who have lower muscle reparative capacity following MV. Reports have shown that the intraoperative intermittent hemidiaphragm electrical stimulation can maintain and/or improve post-surgery diaphragm function. In particular, from a molecular point of view, intermittent electrical stimulation (ES may reduce oxidative stress and increase regulatory autophagy levels, and therefore improve diaphragm function in animal studies. We have recently shown in humans that intraoperative ES attenuates mitochondrial dysfunction and force decline in single diaphragm muscle fibers. The aim of this study was to investigate an effect of ES on oxidative stress, antioxidant status and autophagy biomarker levels in the human diaphragm during surgery. Methods One phrenic nerve was simulated with an external cardiac pacer in operated older subjects (62.4 ± 12.9 years (n = 8 during the surgery. The patients received 30 pulses per min every 30 min. The muscle biopsy was collected from both hemidiaphragms and frozen for further analyses. 4-hydroxynonenal (4-HNE, an oxidative stress marker, and autophagy marker levels (Beclin-1 and the ratio of microtubule-associated protein light chain 3, I and II-LC3 II/I protein concentrations were detected by the Western Blot technique. Antioxidant enzymatic activity copper-zinc (CuZnSOD and manganese (MnSOD superoxide dismutase were analyzed. Results Levels of lipid peroxidation (4-HNE were significantly lower in the stimulated side (p  0.05. Additionally, the protein concentrations of Beclin-1 and the LC3 II/I ratio were higher in the stimulated side (p < 0.05.

    Today, in several north-western European countries, patients are encouraged to choose, actively, a healthcare provider. However, patients often visit the provider that is recommended by their general practitioner (GP). The introduction of patient choice requires GPs to support patients to be involved, actively, in the choice of a healthcare provider. We aim to investigate whether policy on patient choice is reflected in practice, i.e. what the role of the patient is in their choices of healthcare providers at the point of referral and to what extent GPs' and patients' healthcare paths influence the role that patients play in the referral decision. In 2007-2008, we videotaped Dutch GP-patient consultations. For this study, we selected, at random, 72 videotaped consultations between 72 patients and 39 GPs in which the patient was referred to a healthcare provider. These were analysed using an observation protocol developed by the researchers. The majority of the patients had little or no input into the choice of a healthcare provider at the point of referral by their GP. Their GPs did not support them in actively choosing a provider and the patients often agreed with the provider that the GP proposed. Patients who were referred for diagnostic purposes seem to have had even less input into their choice of a provider than patients who were referred for treatment. We found that the GP chooses a healthcare provider on behalf of the patient in most consultations, even though policy on patient choice expects from patients that they choose, actively, a provider. On the one hand, this could indicate that the policy needs adjustments. On the other hand, adjustments may be needed to practice. For instance, GPs could help patients to make an active choice of provider. However, certain patients prefer to let their GP decide as their agent. Even then, GPs need to know patients' preferences, because in a principal-agent relationship, it is necessary that the agent is fully

    Conclusions. Treatment with Insuman® insulins of patients with DM-2, who were not compensated while taking OADs, was associated with improved glycemic control without an increase in the incidence of severe hypoglycemia. There was no statistically significant increase in the effectiveness of therapy in patients, who have successfully completed a training program at diabetes school, compared with evaluation of overall efficiency. The state of young studied population of patients with inadequate control at baseline, and those who had developed cardiovascular complications associated with DM, improved in most cases in terms of glycemic control, and, at that, episodes of severe hypoglycemia were not detected. This may be due to the positive influence of training in diabetes school.

    2012-05-01

    Full Text Available Abstract Background Severe traumatic knee injury, including injury to the anterior cruciate ligament (ACL, leads to impaired sensorimotor function. Although improvements are achieved by training, impairment often persists. Because good sensorimotor function is associated with better patient-reported function and a potential lower risk of future joint problems, more effective treatment is warranted. Temporary cutaneous anesthesia of adjacent body parts was successfully used on the hand and foot to improve sensorimotor function. The aim of this study was to test whether this principle of brain plasticity could be used on the knee. The hypothesis was that temporary anesthesia of the skin area above and below the knee would improve sensorimotor function of the ipsilateral knee and leg in subjects with ACL injury. Methods In this double-blind exploratory study, 39 subjects with ACL injury (mean age 24 years, SD 5.2, 49% women, mean 52 weeks after injury or reconstruction and self-reported functional limitations and lack of trust in the knee were randomized to temporary local cutaneous application of anesthetic (EMLA® (n = 20 or placebo cream (n = 19. Fifty grams of EMLA®, or placebo, was applied on the leg 10 cm above and 10 cm below the center of patella, leaving the area around the knee without cream. Measures of sensory function (perception of touch, vibration sense, knee kinesthesia and motor function (knee muscle strength, hop test were assessed before and after 90 minutes of treatment with EMLA® or placebo. The paired t-test was used for comparisons within groups and analysis of variance between groups, except for ordinal data where the Wilcoxon signed rank test, or Mann–Whitney test, was used. The number of subjects needed was determined by an a priori sample size calculation. Results No statistically significant or clinically relevant differences were seen over time (before vs. after in the measures of sensory or motor

    The aim of this study was to evaluate nutritional status in children who underwent hematopoietic stem cell transplant compared with a healthy control group. A secondary aim was to utilize mid-upper arm circumference as a measure of nutritional status in these groups of children. Our study group included 40 children (18 girls, 22 boys) with mean age of 9.2 ± 4.6 years (range, 2-17 y) who underwent hematopoietic stem cell transplant. Our control group consisted of 20 healthy children (9 girls, 11 boys). The children were evaluated at admission to the hospital and followed regularly 3, 6, 9, and 12 months after discharge from the hospital. In the study group, 27 of 40 patients (67.5%) received nutritional support during hematopoietic stem cell transplant, with 15 patients (56%) receiving enteral nutrition, 6 (22%) receiving total parenteral nutrition, and 6 (22%) receiving enteral and total parenteral nutrition. Chronic malnutrition rate in the study group was 47.5% on admission to the hospital, with the control group having a rate of 20%. One year after transplant, the rate decreased to 20% in the study group and 5% in the control group. The mid-upper arm circumference was lower in children in the study group versus the control group at the beginning of the study (P groups at follow-up examinations (P > .05). During follow-up, all anthropometric measurements increased significantly in both groups. Monitoring nutritional status and initiating appropriate nutritional support improved the success of hematopoietic stem cell transplant and provided a more comfortable process during the transplant period. Furthermore, mid-upper arm circumference is a more sensitive, useful, and safer parameter that can be used to measure nutritional status of children who undergo hematopoietic stem cell transplant.

    The authors have compared the cost effectiveness of contrast arthrography (CA) and nuclear arthrography (NA), in which In-111 chloride is injected with the contrast material, of total hip arthroplasties. Their series included 48 cases of surgically proved loose femoral components. The cost per true-positive result was obtained by taking the total cost of the examinations in surgically proved cases and dividing by the number of true-position cases. The cost of CA was $297 and the cost of NA was $335. For CA, the cost per true positive was $1,018, and for the NA the cost per true positive was $946. In spite of higher initial cost, NA is more cost effective than CA on a cost per true-positive case basis. NA is cost effective in evaluating hip arthroplasties in which there is suspicion of a loose femoral component

    A huge flow of quantitative social, demographic and behavioral data is becoming available that traces the activities and interactions of individuals, social patterns, transportation infrastructures and travel fluxes. This has caused, together with innovative computational techniques and methods for modeling social actions in hybrid (natural and artificial) societies, a qualitative change in the ways we model socio-technical systems. For the first time, society can be studied in a comprehensive fashion that addresses social and behavioral complexity. In other words we are in the position to envision the development of large data and computational cyber infrastructure defining an exploratory of society that provides quantitative anticipatory, explanatory and scenario analysis capabilities ranging from emerging infectious disease to conflict and crime surges. The goal of the exploratory of society is to provide the basic infrastructure embedding the framework of tools and knowledge needed for the design of forecast/anticipatory/crisis management approaches to socio technical systems, supporting future decision making procedures by accelerating the scientific cycle that goes from data generation to predictions.

    Are the concentrations of five criteria air pollutants associated with probabilities of biochemical pregnancy loss and intrauterine pregnancy in women? Increased concentrations of ambient particulate matter (PM10), nitrogen dioxide (NO2), carbon monoxide (CO) during controlled ovarian stimulation (COS) and after embryo transfer were associated with a decreased probability of intrauterine pregnancy. Exposure to high ambient air pollution was suggested to be associated with low fertility and high early pregnancy loss in women. Using a retrospective cohort study design, we analysed 6621 cycles of 4581 patients who underwent one or more fresh IVF cycles at a fertility centre from January 2006 to December 2014, and lived in Seoul at the time of IVF treatment. To estimate patients' individual exposure to air pollution, we computed averages of hourly concentrations of five air pollutants including PM10, NO2, CO, sulphur dioxide (SO2) and ozone (O3) measured at 40 regulatory monitoring sites in Seoul for each of the four exposure periods: period 1 (start of COS to oocyte retrieval), period 2 (oocyte retrieval to embryo transfer), period 3 (embryo transfer to hCG test), and period 4 (start of COS to hCG test). Hazard ratios (HRs) from the time-varying Cox-proportional hazards model were used to estimate probabilities of biochemical pregnancy loss and intrauterine pregnancy for an interquartile range (IQR) increase in each air pollutant concentration during each period, after adjusting for individual characteristics. We tested the robustness of the result using generalised linear mixed model, accounting for within-woman correlation. Mean age of the women was 35 years. Average BMI was 20.9 kg/m2 and the study population underwent 1.4 IVF cycles on average. Cumulative pregnancy rate in multiple IVF cycles was 51.3% per person. Survival analysis showed that air pollution during periods 1 and 3 was generally associated with IVF outcomes. Increased NO2 (adjusted HR = 0.93, 95% CI

    Little is known about coping specificities, as operationalization of the concept of affect regulation, in borderline personality disorder (BPD). It is most important to take into account methodological criticisms addressed to the self-report questionnaire approach and to compare BPD coping specificities to the ones of neighbouring diagnostic categories, such as bipolar disorder (BD). The present exploratory study compared the coping profiles of N = 25 patients presenting BPD to those of N = 25 patients presenting BD and to those of N = 25 healthy controls. All participants underwent a clinical interview that was transcribed and rated using the Coping Patterns observer-rater system. Results partially confirmed study hypotheses and showed differences between BPD patients and healthy controls in all coping domains (competence, resources and autonomy), whereas the only coping domain presenting a BPD-specific lack of skills, compared with the BD patients, was autonomy, a set of coping strategies facing stress appraised as challenge. These coping processes were linked to general and BPD symptomatology. These results extend conclusions of earlier studies on affect regulation processes in BPD and bear important clinical implications, in the context of dialectical behavior therapy and other therapeutic approaches. Limitations of this exploratory study, such as the small sample size, are acknowledged. Coping can be reliably assessed in the narrative process in an non-structured interview frame. Patients with borderline personality disorder present with a specific lack of skills in affect regulation related to autonomy issues, compared to patients with bipolar disorder and healthy controls. Lack of skills in accommodation to distressing emotions in borderline personality disorder is related to symptom gravity and may be treated using radical acceptance strategies.

It is, rather, a short personal essay which attempts to describe an Exploratory Orbit Analysis (EOA) environment. Analyzing the behavior of a four or six dimensional nonlinear dynamical system is at least as difficult as analyzing events in high-energy collisions; the consequences of doing it badly, or slowly, would be at least as devastating; and yet the level of effort and expenditure invested in the latter, the very attention paid to it by physicists at large, must be two orders of magnitude greater than that given to the former. It is difficult to choose the model which best explains the behavior of a physical device if one does not first understand the behavior of the available models. The time is ripe for the development of a functioning EOA environment, which I will try to describe in this paper to help us achieve this goal

    Previous eye-tracking studies using an eye mark recorder have reported that disturbances in exploratory eye movements in adult schizophrenic patients are associated with social functioning. The current study sought to determine whether exploratory eye-movement disturbances are present in children with Asperger's syndrome (AS) compared with typically developing (TD) children. MATERIALS/PARTICIPANTS: The participants were 23 children with AS and 23 age-matched TD children. We measured exploratory eye movements using an EMR-8B eye mark recorder and an exploratory eye movement-measuring device. Eye movements were recorded while participants freely observed a geometric figure (free viewing task), and while they complied with the instructions of an experimenter (repeat-comparison task). We assessed eye fixation points (EFPs) and total eye scanning length (TESL) in all tasks, and measured the responsive search score (RSS) in the repeat-comparison task. In the free viewing task, children with AS exhibited significantly shorter TESL compared with TD children. In the repeat-comparison task, children with AS exhibited significantly lower RSS. Autism Spectrum Screening Questionnaire scores were negatively correlated with both EFP and TESL, but not RSS. The current results revealed that children with AS exhibited dysfunction in exploratory eye movements. Thus, assessing exploratory eye movements in a repeat-comparison task may be useful for detecting social impairment among children with AS. Copyright © 2013 The Japanese Society of Child Neurology.

    To investigate whether biomarkers consisting of baseline characteristics of advanced stage ovarian cancer patients can help in identifying subgroups of patients who would benefit more from primary surgery or neoadjuvant chemotherapy. We used data of the European Organisation for Research and Treatment of Cancer (EORTC) 55971 trial in which 670 patients were randomly assigned to primary surgery or neoadjuvant chemotherapy. The primary outcome was overall survival. Ten baseline clinical and pathological characteristics were selected as potential biomarkers. Using Subpopulation Treatment Effect Pattern Plots (STEPP), biomarkers with a statistically significant qualitative additive interaction with treatment were considered as potentially informative for treatment selection. We also combined selected biomarkers to form a multimarker treatment selection rule. The size of the largest metastatic tumour and clinical stage were significantly associated with the magnitude of the benefit from treatment, in terms of five-year survival (p for interaction: 0.008 and 0.016, respectively). Stage IIIC patients with metastatic tumours ⩽45 mm benefited more from primary surgery while stage IV patients with metastatic tumours >45 mm benefited more from neoadjuvant chemotherapy. In stage IIIC patients with larger metastatic tumours and in stage IV patients with less extensive metastatic tumours both treatments were equally effective. We estimated that by selecting treatments for patients based on largest metastatic tumour and clinical stage, the potential five-year survival rate in the population of treated patients would be 27.3% (95% confidence interval (CI) 21.9-33.0), 7.8% higher than if all were treated with primary surgery, and 5.6% higher if all were treated with neoadjuvant chemotherapy. Although survival was comparable after primary surgery and neoadjuvant chemotherapy in the overall group of patients with ovarian cancer in the EORTC 55971 trial, we found in this exploratory

    Background Today, in several north-western European countries, patients are encouraged to choose, actively, a healthcare provider. However, patients often visit the provider that is recommended by their general practitioner (GP). The introduction of patient choice requires GPs to support patients to be involved, actively, in the choice of a healthcare provider. We aim to investigate whether policy on patient choice is reflected in practice, i.e. what the role of the patient is in their choices of healthcare providers at the point of referral and to what extent GPs’ and patients’ healthcare paths influence the role that patients play in the referral decision. Methods In 2007–2008, we videotaped Dutch GP-patient consultations. For this study, we selected, at random, 72 videotaped consultations between 72 patients and 39 GPs in which the patient was referred to a healthcare provider. These were analysed using an observation protocol developed by the researchers. Results The majority of the patients had little or no input into the choice of a healthcare provider at the point of referral by their GP. Their GPs did not support them in actively choosing a provider and the patients often agreed with the provider that the GP proposed. Patients who were referred for diagnostic purposes seem to have had even less input into their choice of a provider than patients who were referred for treatment. Conclusions We found that the GP chooses a healthcare provider on behalf of the patient in most consultations, even though policy on patient choice expects from patients that they choose, actively, a provider. On the one hand, this could indicate that the policy needs adjustments. On the other hand, adjustments may be needed to practice. For instance, GPs could help patients to make an active choice of provider. However, certain patients prefer to let their GP decide as their agent. Even then, GPs need to know patients’ preferences, because in a principal-agent relationship

    Aim: To determine the frequency of normal variation left atrial anatomy (NVLAA) (diverticula, accessory appendages) and normal variation pulmonary venous anatomy (NVPVA) in patients with atrial fibrillation (AF), and to determine whether the presence of these entities is associated with an increased recurrence of atrial arrhythmias following radiofrequency catheter ablation (RFCA). Materials and methods: All cardiac MDCT images performed prior to RFCA between November 2009 and May 2011 in patients with drug-refractory AF were retrospectively evaluated. The presence, type, and location of NVLAA and NVPVA, and outcome of RFCA were recorded. Success was defined as restoration of sinus rhythm. Results: Forty-six consecutive patients with a mean age of 59.8 (±9.7) years (76.1% male) underwent cardiac MDCT for anatomical planning prior to RFCA procedures. Fourteen (30.4%) patients had NVLAA, 35% of patients had NVPVA. Thirty (65%) patients had successful RFCA: 57% of these had a NVLAA, 67% had NVPVA. Sixteen (35%) patients had unsuccessful RFCA: 63% of these had a NVLAA, 56% had NVPVA. There was no significant association between the presence of NVLAA (p = 0.699), NVPVA (p = 0.197), or “NVLAA in the presence of normal pulmonary venous anatomy” (p = 0.589) and the outcome of RFCA. Conclusion: The presence of NVLAA and NVPVA appears unrelated to adverse outcome in patients undergoing RFCA for the treatment of drug-refractory AF

    The Exploratory Studies Group is dedicated to advanced investigation of accelerators and radiation, primarily in the area of charged-particle beams and photon beams. Its primary mission is to explore the next steps in the development of particle accelerators and storage rings, which are important both for high-energy physics and for the wide range of disciplines now turning to synchrotron-radiation sources and free-electron lasers. Our research is therefore deeply committed to LBL's institutional goal of becoming a center for the generation and use of coherent and incoherent electromagnetic radiation of exceptional brightness, as well as for generic research on the future development of accelerators. A significant fraction of our effort is dedicated to general accelerator-physics research for facilities on the immediate horizon, but a vital part of our activities comprises research into exotic possibilities for charged-particle production, accumulation, acceleration, and storage. During this report period, we were proncipally involved in four general areas of study: Accelerator-physics research for the Advanced Light Source, the 1-2 GeV synchrotron radiation source now under construction at LBL. In collaboration with the Stanford Linear Accelerator Center, both the conceptual and the detailed design of PEP-II, an energy-asymmetric electron-positron collider, based on the PEP ring at SLAC and designed to serve as a B-meson factory. Studies of ultraviolet and infrared free-electron lasers based on linear accelerators and storage rings, in particular the conceptual design of an infrared free-electron laser for the proposed Chemical Dynamics Research Laboratory at LBL. Generic high-energy accelerator-physics and photon-beam research directed far into the future to envision facilities that would employ new techniques of particle-beam acceleration and storage and photon-beam generation

    Full Text Available Autotransplantation of spleen tissue is an attempt for maintenance of splenic functions when splenectomy is indicated in children. It minimizes the risks of overwhelming postsplenectomy infection and it has been done in children with severe portal hypertension due to hepatosplenic mansonic schistosomiasis that underwent splenectomy. The purposes of this investigation were to study the morphology of the residual splenic tissue; to evaluate the residual filtration function of this splenosis; and to assess the immune response to polyvalent pneumococcal vaccine of these patients. Twenty-three children with portal hypertension from mansonic schistosomiasis who underwent splenectomy, ligature of the left gastric vein, autotransplantation of spleen tissue into an omental pouch were evaluated for residual splenic parenchyma and functions. Tc-99m sulfur colloid liver-spleen scans were used for detection of splenic nodules. The search for Howell Jolly bodies were used for assessing the filtration function and Enzyme-linked immunosorbent assay was used for measuring the relative rise in titter of specific pneumococcal antibodies. Splenosis was evident in all children; however, in two there were less than five splenic nodules in the greater omentum, which was considered insufficient. Howell-Jolly bodies were found in the peripheral blood only in these two patients with less evident splenosis. The immune response was adequate in 15 patients; it was intermediate in 4 patients and inadequate in 4 patients. Autotransplantation of spleen tissue into an omental pouch is efficient in maintaining the filtration splenic function in more than 90% of the cases and the immune response to pneumococcal vaccination in approximately 65% of the children.

    Excessive internet use is being discussed as a non-substance-related addiction disorder. Estimations of its prevalence show that 1% of the German general population is affected by internet addiction. However, it is still unclear, whether internet addiction as a co-morbid disorder is also common among patients of the general health care system, especially in patients being treated in inpatient addiction rehabilitation centers. It seems plausible that these patients have a heightened proneness to co-morbid internet addiction. In order to address this issue, a government-funded cooperation project was conducted. Within six months every new patient admitted to one of 15 rehabilitation facilities was screened for internet addiction. 4.2% of the patients fulfilled criteria for internet addiction. Male patients of younger age with main diagnosis of cannabis dependence or pathological gambling were found to be at higher risk. Internet addiction is more common among patients of the rehabilitation system than in the general population. Especially young, male patients in treatment for cannabis dependence or pathological gambling are at risk for co-morbid internet addiction. It is recommended that regular screening for internet addiction should be implemented in facilities with patients at risk in order to offer indicative treatment. © Georg Thieme Verlag KG Stuttgart · New York.

    To investigate whether and how doctors' attachment styles and emotional intelligence (EI) might influence patients' emotional expressions in general practice consultations. Video recordings of 26 junior doctors consulting with 173 patients were coded using the Verona Coding Definition of Emotional Sequences (VR-CoDES). Doctors' attachment style was scored across two dimensions, avoidance and anxiety, using the Experiences in Close Relationships: Short Form questionnaire. EI was assessed with the Mayer-Salovey-Caruso Emotional Intelligence Test. Multilevel Poisson regressions modelled the probability of patients' expressing emotional distress, considering doctors' attachment styles and EI and demographic and contextual factors. Both attachment styles and EI were significantly associated with frequency of patients' cues, with patient- and doctor-level explanatory variables accounting for 42% of the variance in patients' cues. The relative contribution of attachment styles and EI varied depending on whether patients' presenting complaints were physical or psychosocial in nature. Doctors' attachment styles and levels of EI are associated with patients' emotional expressions in primary care consultations. Further research is needed to investigate how these two variables interact and influence provider responses and patient outcomes. Understanding how doctors' psychological characteristics influence PPC may help to optimise undergraduate and postgraduate medical education. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Aim: To characterize progression of Alzheimer’s disease (AD using proton magnetic resonance spectroscopy (1H MRS. Methods: Eleven subjects with mild to moderate AD underwent neurocognitive testing and single-voxel 1H MRS from the precuneus and posterior cingulate region at baseline, after 24 weeks of monotherapy with a cholinesterase inhibitor, and after another 24 weeks of combination therapy with open-label memantine and a cholinesterase inhibitor. Baseline metabolites [N-acetylaspartate (NAA, myo-inositol (mI, choline (Cho, and creatine (Cr] and their ratios in AD subjects were compared with those of an age-matched control group of 28 cognitively normal subjects. Results: AD subjects had significantly higher mI/Cr and lower NAA, NAA/Cr, NAA/Cho, and NAA/mI. Baseline Alzheimer’s Disease Cooperative Study Activities of Daily Living (ADCS-ADL scores significantly correlated with NAA/Cr, mI/Cr, and NAA/mI. There was an increase in mI and a decrease in NAA/mI, but no significant change in other metabolites or ratios, or neurocognitive measures, when memantine was added to a cholinesterase inhibitor. Conclusion: Metabolite ratios significantly differed between AD and control subjects. Baseline metabolite ratios correlated with function (ADCS-ADL. There was an increase in mI and a decrease in NAA/mI, but no changes in other metabolites, ratios, or cognitive measures, when memantine was added to a cholinesterase inhibitor.

    (4S)-4-(3-[(18)F]fluoropropyl)-l-glutamate (BAY 94-9392, alias [(18)F]FSPG) is a new tracer to image x(C)(-) transporter activity with positron emission tomography (PET). We aimed to explore the tumor detection rate of [(18)F]FSPG in patients relative to 2-[(18)F]fluoro-2-deoxyglucose ([(18)F]FDG). The correlation of [(18)F]FSPG uptake with immunohistochemical expression of x(C)(-) transporter and CD44, which stabilizes the xCT subunit of system x(C)(-), was also analyzed. Patients with non-small cell lung cancer (NSCLC, n = 10) or breast cancer (n = 5) who had a positive [(18)F]FDG uptake were included in this exploratory study. PET images were acquired following injection of approximately 300 MBq [(18)F]FSPG. Immunohistochemistry was done using xCT- and CD44-specific antibody. [(18)F]FSPG PET showed high uptake in the kidney and pancreas with rapid blood clearance. [(18)F]FSPG identified all 10 NSCLC and three of the five breast cancer lesions that were confirmed by pathology. [(18)F]FSPG detected 59 of 67 (88%) [(18)F]FDG lesions in NSCLC, and 30 of 73 (41%) in breast cancer. Seven lesions were additionally detected only on [(18)F]FSPG in NSCLC. The tumor-to-blood pool standardized uptake value (SUV) ratio was not significantly different from that of [(18)F]FDG in NSCLC; however, in breast cancer, it was significantly lower (P < 0.05). The maximum SUV of [(18)F]FSPG correlated significantly with the intensity of immunohistochemical staining of x(C)(-) transporter and CD44 (P < 0.01). [(18)F]FSPG seems to be a promising tracer with a relatively high cancer detection rate in patients with NSCLC. [(18)F]FSPG PET may assess x(C)(-) transporter activity in patients with cancer.

    Background. With an ageing and increasingly diverse population at risk from rising levels of obesity, diabetes and cardiovascular disease, including kidney complications, there is a need to provide quality care at all stages in the care pathway including at the end of life and to all patients. Aim . This study purposively explored South Asian patients' experiences of kidney end of life care to understand how services can be delivered in a way that meets diverse patient needs. Methods. Within an action research design 14 focus groups (45 care providers) of kidney care providers discussed the recruitment and analysis of individual interviews with 16 South Asian kidney patients (eight men, eight women). Emergent themes from the focus groups were analysed thematically. The research took place at four UK centres providing kidney care to diverse populations: West London, Luton, Leicester and Bradford. Results. Key themes related to time and the timing of discussions about end of life care and the factors that place limitations on patients and providers in talking about end of life care. Lack of time and confidence of nurses in areas of kidney care, individual attitudes and workforce composition influence whether and how patients have access to end of life care through kidney services. Conclusion. Training, team work and time to discuss overarching issues (including timing and communication about end of life) with colleagues could support service providers to facilitate access and delivery of end of life care to this group of patients.

    This study investigated the relationships between Type D personality, depression, and social support among ethnic Chinese coronary artery disease (CAD) patients undergoing percutaneous coronary interventions. Type D personality is associated with CAD, and may increase patients' depression and mortality rate. However, very few studies have explored the relationships between depression and social support among ethnic Chinese Type D CAD patients. A longitudinal, repeated-measures design was used; 105 Taiwanese CAD patients undergoing a percutaneous coronary intervention were recruited between January and December 2015. A demographic questionnaire, Type D Scale, ENRICHD Social Support Inventory, and Patient Health Questionnaire-9 were completed by 102 participants (mean age = 64.42, SD = 13.67 years) at hospitalization, and at the second week and third month after discharge. Data were analyzed using t tests and a generalized estimating equation. Results indicated that 46.7% of participants who had Type D personality had lower social support and higher depression than did the remaining (non-Type D) participants. At two weeks after discharge, the improvement in social support was higher among Type D patients than non-Type D participants; the same was true for depression at two weeks and three months after discharge each. Type D Taiwanese CAD patients showed lower perceived social support and higher depression during hospitalization than did non-Type D participants. Furthermore, the more social support patients received at home, the lower was their depression. Health-care providers should provide continuous mental health care, conduct early screening of mental health issues, and ensure that patients receive sufficient social support to reduce depression.

    To examine the major factors affecting patients' perception of cumulative satisfaction and to address the question whether patients in Egypt and Jordan evaluate quality of health care similarly or differently. A conceptual model including behavioural dimensions of patient-physician relationships and patient satisfaction has been developed. As the empirical research setting, this study concerns three hospitals in Egypt and Jordan. The survey instrument in a questionnaire form was designed to achieve the research objectives. A total of 48 items (attributes) of the newly developed five quality dimensions were identified to be the most relevant. A total of 224 complete and usable questionnaires were received from the in-patients. Hospital C has above-average total and dimensional qualities and patients are the most satisfied in accordance with all dimensions of services. Hospitals A and B have under-average total qualities as the majority of patients are not satisfied with services. Comparing hospitals A and B, in the majority of dimensions (with the exception of Q5), the quality in hospital B is higher than in hospital A. Patients' satisfaction with different service quality dimensions is correlated with their willingness to recommend the hospital to others. A cure to improve the quality for health-care services can be an application of total relationship management and the 5Qs model together with customer orientation strategy. The result can be used by the hospitals to reengineer and redesign creatively their quality management processes and the future direction of their more effective health-care quality strategies. In this research a study is described involving a new instrument and a new method which assure a reasonable level of relevance, validity and reliability, while being explicitly change-oriented. This study argues that a patient's satisfaction is a cumulative construct, summing satisfaction with five different qualities (5Qs) of the hospital: quality of

    This study examined patterns in the use of health information among Caucasian, Japanese, and non-Japanese Asian Pacific Islander cancer patients in Hawaii and explored the relation of ethnicity and educational level to choices of health information sources. Information from 140 cancer patients, most of whom were users of complementary and alternative medicine (CAM), was analyzed using correspondence analysis. Three clusters of health information pertinent to the three ethnic groups emerged from the data. The results of this study revealed that Caucasian patients preferred objective, scientific, and updated information obtained through medical journals or newsletters from research institutions, telephone information services, and the internet. Japanese patients relied on media and commercial sources including television, newspapers, books, magazines and CAM providers. Non-Japanese Asians and Pacific Islanders used information sources involving person-to-person communication with their physicians, social groups, and other cancer patients. A higher educational level was closely related to a cluster of health information stressing objective, scientific and updated information, while a lower educational level was associated with interpersonally communicated information. The three ethnicity-specific patterns of health information use remained relatively stable at different educational levels, implying that the effect of patients' ethnicity overrides their educational level in shaping their choices of health information. The results of this study indicate the importance of recognizing cancer patients' culturally developed world views when understanding their health information-seeking behavior. For medical practice, these findings indicate the need for healthcare providers to assist cancer patients to obtain accurate health information in a culturally sensitive way.

    When patients are facing the ends of their lives, spiritual concerns often become more important. It is argued that effective, integrated palliative care should include addressing patients' spiritual wellbeing. In 2002 the EORTC Quality of Life Group began an international study to develop an spiritual wellbeing measure for palliative patients (SWB). Spiritual wellbeing is a complex construct, which comprises multiple contributory components. While conducting the EORTC SWB validation study with Dutch palliative cancer patients we also conducted an exploratory side study to examine the relationship between their spiritual wellbeing, images of God, and attitudes towards death. Patients with incurable cancer who were able to understand Dutch and were well enough to participate, completed the provisional SWB measure and two scales assessing "Images of God" and "attitudes towards death and afterlife". Linear stepwise regression analysis was conducted to assess the relation between SWB and other factors. Fifty two Dutch patients, 28 females and 24 males, participated. The whole SWB measure validation identified four scoring scales: Existential (EX), Relationship with Self (RS), Relationships with Others (RO), Relationship with Something Greater (RSG) and Relationship with God (RG, for believers only). Adherence to an image of an Unknowable God and a worse WHO performance status were negatively associated with the EX scale. The image of an Unknowable God was also found to be negatively associated with the RS scale. Higher education correlated positively with the RO scale. Adherence to a Personal or Non-Personal Image of God was not found to be positively influencing any of the domains of SWB. For our participants, an Unknowable Image of God had a negative relationship with their SWB. Furthermore, specific images of God (Personal or Non Personal) are not associated with domains of SWB. Together, these findings suggest that spiritual wellbeing surpasses traditional

    To explore (1) the information obtained from related but conceptually different approaches to pain assessment and (2) the extent to which the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) can be used as a screening tool to predict patient-reported need for pain relief. Cancer patients randomly sampled from 56 hospital departments were included. Questionnaire items assessed patients' (a) pain experience using the EORTC QLQ-C30 pain scale and its two pain items separately (pain intensity and pain interference) and (b) pain burden and (c) need for pain relief using the Three-Levels-of-Needs Questionnaire (3LNQ). Of the 2364 patients contacted by mail, 1447 (61 %) completed the questionnaires. Among these, 51 % reported at least "a little" pain on the pain intensity item. The number of patients reporting pain to be a burden was similar, and pain experience and pain burden were highly correlated (correlation coefficients ranged from 0.85 to 0.91). Pain experience and pain burden were moderately correlated with the need for pain relief. A receiver-operating characteristic (ROC) curve analysis showed that the EORTC QLQ-C30 discriminated between patients with and without a need for pain relief to an acceptable degree (area under the curve (AUC) 0.73-0.77). The cut-point a little gave a sensitivity of 84 % and specificity of 59 % for the item "Have you had pain?" and a sensitivity of 72 % and a specificity of 72 % for the pain scale. The majority of patients who experienced pain felt it to be a problem. Pain experience and pain burden were substantially related to need for pain relief, and the latter could be predicted from the EORTC QLQ-C30.

    Full Text Available Background: According to the Global Initiative for Asthma (GINA, the levels of asthma symptom control can be divided into controlled, partially controlled and uncontrolled asthma. Optional therapy for non-steroidal anti-inflammatory drugs (NSAIDs-hypersensitive asthmatics uses aspirin desensitization, but until now, this therapy is not established in difficult to treat cases. The aim of this study was to evaluate the efficacy of aspirin desensitization in patients with poorly controlled asthma. Methods: Patients with poorly controlled asthma, NDAIDs hypersensitivity and aspirin desensitization were included in the retrospective study. The data were compared to those obtained from patients with controlled asthma and aspirin therapy. Lung function, levels of asthma symptom control, asthma medication, the size of nasal polyps (NP and smell function were evaluated over 18 months. Results: Thirty-two patients were included in the study (uncontrolled/partially controlled asthma n = 12; controlled asthma n = 20. After 18 months of follow-up, the patients with poorly controlled asthma had significantly increased forced expiratory volume in 1 s (FEV1 values, as compared to the baseline (66–82%; p = 0.02, the levels of asthma control improved significantly (p  0.05 and the asthma medication was constant. In relation to nasal parameters the sense of smell improved significantly in both groups, NP-scores did not differ significantly. Conclusions: Patients with a poorly controlled asthma and NSAIDs hypersensitivity profit from an add-on aspirin therapy.

    In a pooled analysis of short-term trials, short-term treatment with the sodium-glucose co-transporter-2 (SGLT2) inhibitor empagliflozin reduced albuminuria in patients with type 2 diabetes and prevalent albuminuria. In this exploratory analysis of the EMPA-REG OUTCOME trial, we report the short-term and long-term effects of empagliflozin on albuminuria in patients with type 2 diabetes and established cardiovascular disease, according to patients' baseline albuminuria status. In this randomised, double-blind, placebo-controlled trial at 590 sites in 42 countries, we randomly assigned patients aged 18 years and older with type 2 diabetes and established cardiovascular disease (1:1:1) to empagliflozin 10 mg, empagliflozin 25 mg, or placebo in addition to standard of care until at least 691 patients experienced an adjudicated event included in the primary outcome. We did the randomisation with a computer-generated random-sequence and interactive voice-response and web-response system, stratified by HbA 1c , BMI, region, and estimated glomerular filtration rate. Patients, investigators, and individuals involved in analysis of trial data were masked to treatment assignment. The primary and secondary efficacy and safety endpoints of this trial have been reported previously. Here, we report urinary albumin-to-creatinine ratio (UACR) data for the pooled empagliflozin group versus placebo according to albuminuria status at baseline (normoalbuminuria: UACR 300 mg/g). We did the analysis with mixed-model repeated measures including prespecified and post-hoc tests. This study is completed and registered with ClinicalTrials.gov, number NCT01131676. Between Sept 1, 2010, and April 22, 2013, we randomly assigned 7028 patients to treatment groups and 7020 patients received treatment. At baseline, we had UACR data for 6953 patients: 4171 (59% of treated patients; 1382 assigned to placebo and 2789 assigned to empagliflozin) had normoalbuminuria, 2013 (29%; 675 assigned to placebo

    Sarcopenia is generally complicated with patients with chronic heart failure (CHF) and its presence negatively affects the course of heart failure, however effective nutritional intervention had not been elucidated yet. The primary objective of this study is to explore whether the addition of a branched-chain amino acid (BCAA) preparation for cardiac rehabilitation (CR) of patients with CHF further improves cardiopulmonary functions, skeletal muscle functions, and metabolism in comparison with conventional CR. This is a randomized, parallel-group comparative study. The elderly patients that were participated in CR and complicated with left ventricular systolic or diastolic dysfunction are randomized into two groups, CR + BCAA and CR. 20 weeks later, the second randomization is performed, which divide subjects into two groups with and without BCAA intervention without CR. Primary outcome measure is the rate of change of the anaerobic threshold workload from baseline to post-intervention. Secondary outcome include parameters of exercise capacity, cardiac function and psychological status. In the current study the effect of a promising new intervention, BCAA, will be assessed to determine whether its addition to CR improve exercise capacity in patients with heart failure, who are generally complicated with sarcopenia. This clinical trial was registered with the University Hospital Medical Information Network-Clinical Trials Registry (UMIN-CTR; JPRN-UMIN R000022440 ).

    Prefrontal repetitive Transcranial Magnetic Stimulation (rTMS) may improve negative symptoms in patients with schizophrenia, but few studies have investigated the underlying neural mechanism. This study aims to investigate changes in the levels of glutamate and glutamine (Glx, neurotransmitter and precursor) and N-Acetyl Aspartate (NAA) in the left dorsolateral prefrontal cortex of patients with schizophrenia treated with active bilateral prefrontal rTMS as compared to sham-rTMS, as measured with 1 H-Magnetic Resonance Spectroscopy ( 1 H-MRS). Patients were randomized to a 3-week course of active or sham high-frequency rTMS. Pre-treatment and post-treatment 1 H-MRS data were available for 24 patients with schizophrenia with moderate to severe negative symptoms (Positive and Negative Syndrome Scale (PANSS) negative subscale ≥ 15). Absolute metabolite concentrations were calculated using LCModel with the water peak as reference. To explore the association between treatment condition and changes in concentration of Glx and NAA, we applied a linear regression model. We observed an increase of Glx concentration in the active treatment group and a decrease of Glx concentration in the group receiving sham treatment. The association between changes in Glx concentration and treatment condition was significant. No significant associations between changes in NAA and treatment condition were found. Noninvasive neurostimulation with high-frequency bilateral prefrontal rTMS may influence Glx concentration in the prefrontal cortex of patients with schizophrenia. Larger studies are needed to confirm these findings and further elucidate the underlying neural working mechanism of rTMS. Copyright © 2016 Elsevier Inc. All rights reserved.

    Our objectives were: (a) to identify predictors of change in health-related quality of life (HRQOL) in patients with advanced non-small cell lung cancer (NSCLC) undergoing chemotherapy; and (b) to characterize symptom status, nutritional status, physical performance and HRQOL in this population and to estimate the extent to which these variables change following two cycles of chemotherapy. A secondary analysis of a longitudinal observational study of 47 patients (24 men and 23 women) with newly diagnosed advanced NSCLC receiving two cycles of first-line chemotherapy was performed. Primary outcomes were changes in HRQOL (physical and mental component summaries (PCS and MCS) of the 36-item Short-Form Health Survey (SF-36)). Predictors in the models included pre-chemotherapy patient-reported symptoms (Schwartz Cancer Fatigue Scale (SCFS) and Lung Cancer Subscale), nutritional screening (Patient-Generated Subjective Global Assessment) and physical performance measures (6-min Walk Test (6MWT), one-minute chair rise test and grip strength). Mean SF-36 PCS score, 6MWT distance and grip strength declined following two cycles of chemotherapy (pmental component of HRQOL accounting for 13% and 9% of the variance, respectively. No significant predictors were found for change in the physical component of HRQOL. Pre-chemotherapy 6MWT distance and fatigue severity predicted change in the mental component of HRQOL in patients with advanced NSCLC undergoing chemotherapy, while physical performance declined during treatment. Clinical management of these factors may be useful for HRQOL optimization in this population. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    The role of HLA-G in several clinical conditions related to reproduction has been investigated. Important polymorphisms have been found within the 5'URR and 3'UTR regions of the HLA-G promoter. The aim of the present study was to investigate 16 SNPs in the 5'URR and 14-bp insertion/deletion (ins/del) polymorphism located in the 3'UTR region of the HLA-G gene and its possible association with the implantation outcome in couples who underwent assisted reproduction treatments (ART). The case group was composed of 25 ART couples. Ninety-four couples with two or more term pregnancies composed the control group. Polymorphism haplotype frequencies of the HLA-G were determined for both groups. The Haplotype 5, Haplotype 8 and Haplotype 11 were absolute absence in ART couples. The HLA-G*01:01:02a, HLA-G*01:01:02b alleles and the 14-bp ins polymorphism, Haplotype 2, showed an increased frequency in case women and similar distribution between case and control men. However, this susceptibility haplotype is significantly presented in case women and in couple with failure implantation after treatment, which led us to suggest a maternal effect, associated with this haplotype, once their presence in women is related to a higher number of couples who underwent ART.

    Full Text Available Background. S100B protein, previously proposed as a consolidated marker of brain damage in congenital heart disease (CHD newborns who underwent cardiac surgery and cardiopulmonary bypass (CPB, has been progressively abandoned due to S100B CNS extra-source such as adipose tissue. The present study investigated CHD newborns, if adipose tissue contributes significantly to S100B serum levels. Methods. We conducted a prospective study in 26 CHD infants, without preexisting neurological disorders, who underwent cardiac surgery and CPB in whom blood samples for S100B and adiponectin (ADN measurement were drawn at five perioperative time-points. Results. S100B showed a significant increase from hospital admission up to 24 h after procedure reaching its maximum peak (P0.05 have been found all along perioperative monitoring. ADN/S100B ratio pattern was identical to S100B alone with the higher peak at the end of CPB and remained higher up to 24 h from surgery. Conclusions. The present study provides evidence that, in CHD infants, S100B protein is not affected by an extra-source adipose tissue release as suggested by no changes in circulating ADN concentrations.

    Oxidative stress markers seem to be higher in patients with anorexia nervosa (AN) than healthy controls, but the potentially beneficial effects of weight gain is not known. We calculated random effects standardised mean differences (SMDs) as effect size measures of oxidative stress marker changes after re-alimentation reported in two or more studies, summarising others descriptively. Seven longitudinal studies (n = 104) were included. After a median follow-up period of 8 weeks, AN patients significantly increased their body mass index (15.1 ± 2.1 to 17.1 ± 2.2, p alimentation, even without full-weight normalisation, seems to improve oxidative stress in people with AN.

    Some patients with chronic obstructive pulmonary disease (COPD) fail to achieve health benefits with pulmonary rehabilitation (PR). Exercise intensity and load represent stimulus for adaptation but it is unclear whether inappropriate exercise intensity and/or load are affected by severity of COPD, which may affect health benefits. The purpose was to determine whether COPD severity and/or the severity of pulmonary limitation to exercise (PLE) impacted exercising intensity or load and whether resultant intensity/load affected health outcomes derived from PR. Patients with COPD (n = 58, age = 67 ± 7 y, forced expiratory volume in the first second of expiration [FEV1] % predicted = 52 ± 21%) were recruited upon referral to PR. Primary health outcomes evaluated were 6-min walk distance and St George's Respiratory Questionnaire. Patients were stratified for disease severity using Global Initiative for Obstructive Lung Disease (GOLD) staging and PLE severity by change in inspiratory capacity during exercise. Exercise intensity and load were calculated from daily exercise records. Participants achieved comparable training duration and load regardless of GOLD severity. Patients with more severe PLE achieved greater training duration (more severe: 546 ± 143 min., less severe: 451 ± 109 min., P = .036), and relative training load (more severe: 2200.8 ± 595.3 kcal, less severe: 1648.3 ± 597.8 kcal, P = .007). Greater overall training load was associated with greater improvements in 6-min walk distance (r = 0.24, P = .035). No significant relationships were observed between PLE, GOLD severity, training parameters, and St George's Respiratory Questionnaire response. Improvements in exercise tolerance can be explained by achieving greater training loads, demonstrating the importance of appropriate training load to maximize health outcomes in PR.

    There have been few large-scale, real world studies in Spain to assess change in pain and quality of life (QOL) outcomes in cancer patients with moderate to severe pain. This study aimed to assess changes on both outcomes after 3 months of usual care and to investigate factors associated with change in QoL. Large, multi-centre, observational study in patients with lung, head and neck, colorectal or breast cancer experiencing a first episode of moderate to severe pain while attending one of the participating centres. QoL was assessed using the EuroQol-5D questionnaire and pain using the Brief Pain Inventory (BPI). Instruments were administered at baseline and after 3 months of follow up. Multivariate analyses were used to assess the impact of treatment factors, demographic and clinical variables, pain and other symptoms on QoL scores. 1711 patients were included for analysis. After 3 months of usual care, a significant improvement was observed in pain and QoL in all four cancer groups (pbreast cancer patients showed the largest gains. Poorer baseline performance status (ECOG) and the presence of anxiety/depression were associated with significantly poorer QOL outcomes. Improvements in BPI pain scores were associated with improved QoL. In the four cancer types studied, pain and QoL outcomes improved considerably after 3 months of usual care. Improvements in pain made a substantial contribution to QoL gains whilst the presence of anxiety and depression and poor baseline performance status significantly constrained improvement.

  8. Trenching as an exploratory method

    The critical nature of siting nuclear power plants has led to increased emphasis on exploratory trenching. Trenching is the most definitive of all subsurface exploratory methods; it permits inspection of a continuous geologic section by both geologists and regulatory authorities and makes possible the preparation of a graphic log that delineates both obvious and subtle geologic features. About one of every two nuclear plant licensing efforts utilizes exploratory trenching. Many geologic hazards, such as ''capable'' faults, can be detected from trench exposures; they may otherwise remain undetected. Trenches must be judiciously located, survey-controlled, excavated safely and adequately shored, logged in detail, and properly diagnosed. Useful techniques of trench logging include thorough cleaning of the trench walls, teamwork between geologist and recorder, logging against a carefully surveyed baseline and vertical reference grid, and panoramic photography.Soils, including paleosols, and glacial and glaciofluvial deposits present some of the most difficult media to log. Trench logs must be thoroughly interpreted and correlated so that they document the geologic conditions governing suitability of the site. Age-determination techniques utilized in exploratory trenching include petrographic analyses, quartz inclusion studies, clay mineralogic analyses, and radiometric methods

    Attention and assessment biases are part of body image disturbances shown by patients with anorexia nervosa (AN). The aim of this article was to study these biases by using eye movement analyses. As stimuli, the study used 24 standardized pictures showing young women and a standardized picture of the respective study participant. With an eye movement tracer, we were able to determine what body areas that the study participants look at. The study participants were also asked to rate the attractiveness of the stimuli. Data from 35 patients with AN and 32 healthy controls were included. Patients with AN judge their own body areas as being less attractive than the controls on a rating scale from 1 to 5 (e.g., breasts: mean [standard deviation] = 0.9 [1.0] versus 2.2 [0.8], p < .001). They were also more critical in their assessment of the bodies of others (e.g., attractiveness of people with ideal weight: 2.1 [0.9] versus 2.8 [0.5], p < .001). They spent less time looking at their own breasts (1.8 [0.9] versus 2.2 [1.0] seconds, p = .09) but significantly more time at their thighs (1.1 [0.6] versus 0.8 [0.4] seconds, p = .05). The results confirm the assumption of cognitive biases. The differences, however, are often small and vary greatly.

    Characterizing relationships between pain relief and function can inform patient management decisions. This analysis explored graphically the relationship between pain relief and functional improvement in patients with neuropathic pain associated with spinal cord injury in two clinical trials of pregabalin. This was a post hoc analysis of two randomized, double-blind, clinical trials in patients who were treated with pregabalin (n=181) or placebo (n=172) for neuropathic pain associated with spinal cord injury. The bivariate relationship between percent pain relief and absolute change in the functional outcomes with placebo and pregabalin was evaluated graphically using scatter plots, and loess curves illustrated the extent of the relationship between pain and function. Linear trend analysis evaluated the statistical significance of these relationships using Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT)-based thresholds of pain reduction (Pain Inventory pain interference with function in one of the studies and the Medical Outcomes Study Sleep Scale (an 11-point Numeric Rating Scale) and the Hospital Anxiety and Depression Scale (HADS) for the pooled studies. Data ellipses showed a shift with pregabalin relative to placebo toward greater improvement with increasing pain relief for all outcome measures except HADS. Loess curves suggested a relationship between increased pain relief and improved function except for HADS, with the clearest relationship observed for sleep. Linear trend analysis showed significant relationships between pain and Medical Outcomes Study Sleep Scale (Ppain and function on the modified Brief Pain Inventory Interference Index and most individual items (Ppain reduction. Pregabalin resulted in shifts from placebo toward greater functional improvement with greater pain relief.

    A reason for empathy decline during medical training has not been fully elucidated. Empathy may decrease acutely during an inpatient hematology-oncology rotation because of the acuity of death exposures. This study aimed to explore physician trainee empathy, distress, death exposures, and their attributed meaning for the trainee. Internal medicine interns and residents at a single academic center were evaluated before and after hematology-oncology ward rotations using Interpersonal Reactivity Index for empathy, previously cited reasons for empathy decline, Impact of Event Scale-Revised for distress, death exposures (no. of dying patients cared for) and attributed sense of meaning (yes/no) (post-rotation). Fifty-six trainees completed both pre-rotation and post-rotation questionnaires (58% response). Empathy averaged 58.9 (SD 12.0) before and 56.8 (SD 11.1) after the rotation (2.1 point decrease) (p = 0.018). Distress was elevated but did not change significantly during the rotation. Residents cared for 4.28 dying patients. Seventy-three percent reported that death was the most stressful event during the rotation, yet 68% reported that they derived a sense of meaning from caring for dying patients. Empathy and distress scales were positively correlated before the rotation (r = 0.277, p = 0.041) but not after (r = .059, p = 0.69). This study suggests that an acute drop in empathy can occur over several weeks in residents rotating through inpatient hematology-oncology, similar to empathy decline associated with years of training in other studies. Empathy decline may be associated with elevated distress and death exposures on the hematology-oncology ward and should be explored further in other medical training environments.

    This article is a report on a study to examine the pain situation, the use of oral analgesics and non-pharmacological strategies and the psychological well-being of older patients living in nursing homes; the relationships between pain and psychological well-being were also explored. Pain is common among older adults world-wide, and tends to be under-treated. Indeed, the high prevalence of pain may further hinder the fulfilment of psychological needs in a Maslow hierarchy of needs model. It was a quantitative cross-sectional study; older adults from six nursing homes were invited to join the study in 2007-2009, with a response rate of 100%. Pain was measured using the Geriatric Pain Assessment, happiness using the Subjective Happiness Scale, life satisfaction using the Life Satisfaction Index - A Form, loneliness using the Revised UCLA Loneliness Scale and depression was measured using the Geriatric Depression Scale. A convenience sample of 302 older patients (213 females and 89 males aged from 60 to 101, mean age of 84·99) joined the study. The majority of them had experienced pain in the previous 3 months, with a pain intensity of 4·51 on a 10-point scale. Pain sites were mainly the knee, back, shoulder and musculoskeletal areas. Only 50% of them took oral analgesics, and 70% used non-pharmacological measures for pain relief. The pain group reported significantly more loneliness and depression when compared with their no-pain counterparts. As the number of older patients increases, so does the need for alternative accommodation; thus, pain management education is urgently needed for staff and nursing home residents. © 2011 The Authors.

    Agomelatine is a newer antidepressant but, to date, no studies have been carried out investigating its effects on C-reactive protein (CRP) levels in major depressive disorder (MDD) before and after treatment. The present study aimed (i) to investigate the effects of agomelatine treatment on CRP levels in a sample of patients with MDD and (ii) to investigate if CRP variations were correlated with clinical improvement in such patients. 30 adult outpatients (12 males, 18 females) with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) diagnosis of MDD were recruited in "real-world," everyday clinical practice and treated with a flexible dose of agomelatine for 12 weeks. The Hamilton Rating Scale for Depression (HAM-D) and the Snaith-Hamilton Pleasure Scale (SHAPS) were used to evaluate depressive symptoms and anhedonia, respectively. Moreover, serum CRP was measured at baseline and after 12 weeks of treatment. Agomelatine was effective in the treatment of MDD, with a significant reduction in HAM-D and SHAPS scores from baseline to endpoint. CRP levels were reduced in the whole sample, with remitters showing a significant difference in CRP levels after 12 weeks of agomelatine. A multivariate stepwise linear regression analysis showed that higher CRP level variation was associated with higher baseline HAM-D scores, controlling for age, gender, smoking, BMI, and agomelatine dose. Agomelatine's antidepressant properties were associated with a reduction in circulating CRP levels in MDD patients who achieved remission after 12 weeks of treatment. Moreover, more prominent CRP level variation was associated with more severe depressive symptoms at baseline.

This analysis explored graphically the relationship between pain relief and functional improvement in patients with neuropathic pain associated with spinal cord injury in two clinical trials of pregabalin. Methods: This was a post hoc analysis of two randomized, double-blind, clinical trials in patients who were treated with pregabalin (n=181 or placebo (n=172 for neuropathic pain associated with spinal cord injury. The bivariate relationship between percent pain relief and absolute change in the functional outcomes with placebo and pregabalin was evaluated graphically using scatter plots, and loess curves illustrated the extent of the relationship between pain and function. Linear trend analysis evaluated the statistical significance of these relationships using Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT-based thresholds of pain reduction (<15%, 15% <30%, 30% to <50%, and ≥50%. Outcome measures included modified Brief Pain Inventory pain interference with function in one of the studies and the Medical Outcomes Study Sleep Scale (an 11-point Numeric Rating Scale and the Hospital Anxiety and Depression Scale (HADS for the pooled studies. Results: Data ellipses showed a shift with pregabalin relative to placebo toward greater improvement with increasing pain relief for all outcome measures except HADS. Loess curves suggested a relationship between increased pain relief and improved function except for HADS, with the clearest relationship observed for sleep. Linear trend analysis showed significant relationships between pain and Medical Outcomes Study Sleep Scale (P<0.0001 and between pain and function on the modified Brief Pain Inventory

    Org 26576 acts by modulating ionotropic AMPA-type glutamate receptors to enhance glutamatergic neurotransmission. The aim of this Phase 1b study (N=54) was to explore safety, tolerability, pharmacokinetics, and pharmacodynamics of Org 26576 in depressed patients. Part I (N=24) evaluated the maximum tolerated dose (MTD) and optimal titration schedule in a multiple rising dose paradigm (range 100 mg BID to 600 mg BID); Part II (N=30) utilized a parallel groups design (100 mg BID, 400 mg BID, placebo) to examine all endpoints over a 28-day dosing period. Based on the number of moderate intensity adverse events reported at the 600 mg BID dose level, the MTD established in Part I was 450 mg BID. Symptomatic improvement as measured by the Montgomery-Asberg Depression Rating Scale was numerically greater in the Org 26576 groups than in the placebo group in both study parts. In Part II, the 400 mg BID dose was associated with improvements in executive functioning and speed of processing cognitive tests. Org 26576 was also associated with growth hormone increases and cortisol decreases at the end of treatment but did not influence prolactin or brain-derived neurotrophic factor. The quantitative electroencephalogram index Antidepressant Treatment Response at Week 1 was able to significantly predict symptomatic response at endpoint in the active treatment group, as was early improvement in social acuity. Overall, Org 26576 demonstrated good tolerability and pharmacokinetic properties in depressed patients, and pharmacodynamic endpoints suggested that it may show promise in future well-controlled, adequately powered proof of concept trials.

    There is little evidence on how primary care providers (PCPs) model their practices in Nova Scotia (NS), Canada, what services they offer or what accessibility is like for the average patient. This study will create a database of all family physicians and primary healthcare nurse practitioners in NS, including information about accessibility and the model of care in which they practice, and will link the survey data to administrative health databases. 3 census surveys of all family physicians, primary care nurse practitioners (ie, PCPs) and their practices in NS will be conducted. The first will be a telephone survey conducted during typical daytime business hours. At each practice, the person answering the telephone will be asked questions about the practice's accessibility and model of care. The second will be a telephone survey conducted after typical daytime business hours to determine what out-of-office services PCP practices offer their patients. The final will be a tailored fax survey that will collect information that could not be obtained in the first 2 surveys plus new information on scope of practice, practice model and willingness to participate in research. Survey data will be linked with billing data from administrative health databases. Multivariate regression analysis will be employed to assess whether access and availability outcome variables are associated with PCP and model of practice characteristics. Negative binomial regression analysis will be employed to assess the association between independent variables from the survey data and health system use outcomes from administrative data. This study has received ethical approval from the Nova Scotia Health Authority and the Health Data Nova Scotia Data Access Committee. Dissemination approached will include stakeholder engagement at local and national levels, conference presentations, peer-reviewed publications and a public website.

    Language support for linguistic minorities can improve patient safety, clinical outcomes and the quality of health care. Most chronic hepatitis B/C infections in Europe are detected among people born in endemic countries mostly in Africa, Asia and Central/Eastern Europe, groups that may experience language barriers when accessing health care services in their host countries. We investigated availability of interpreters and translated materials for linguistic minority hepatitis B/C patients. We also investigated clinicians' agreement that language barriers are explanations of three scenarios: the low screening uptake of hepatitis B/C screening, the lack of screening in primary care, and why cases do not reach specialist care. An online survey was developed, translated and sent to experts in five health care services involved in screening or treating viral hepatitis in six European countries: Germany, Hungary, Italy, the Netherlands, Spain and the United Kingdom (UK). The five areas of health care were: general practice/family medicine, antenatal care, health care for asylum seekers, sexual health and specialist secondary care. We measured availability using a three-point ordinal scale ('very common', 'variable or not routine' and 'rarely or never'). We measured agreement using a five-point Likert scale. We received 238 responses (23% response rate, N = 1026) from representatives in each health care field in each country. Interpreters are common in the UK, the Netherlands and Spain but variable or rare in Germany, Hungary and Italy. Translated materials are rarely/never available in Hungary, Italy and Spain but commonly or variably available in the Netherlands, Germany and the UK. Differing levels of agreement that language barriers explain the three scenarios are seen across the countries. Professionals in countries with most infrequent availability (Hungary and Italy) disagree strongest that language barriers are explanations. Our findings show pronounced

    The traditional interpretation of symptom over-reporting is that it indicates malingering. We explored a different perspective, namely that over-reporting of eccentric symptoms is related to deficits in articulating internal experiences (i.e., alexithymia). Given that alexithymia has been linked to sleep problems and that fatigue may fuel inattentive responding to symptom lists, we administered measures of alexithymia (TAS-20) and symptom over-reporting (SIMS), but also sleep quality (SLEEP-50) to forensic psychiatric outpatients (n = 40) and non-forensic participants (n = 40). Forensic patients scored significantly higher on all three indices than non-forensic participants. In the total sample as well as in subsamples, over-reporting correlated positively and significantly with alexithymia, with rs being in the 0.50-0.65 range. Sleep problems were also related to over-reporting, but in the full sample and in the forensic subsample, alexithymia predicted variance in over-reporting over and above sleep problems. Although our study is cross-sectional in nature, its results indicate that alexithymia as a potential source of over-reporting merits systematic research. © 2018 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

    The present study aimed to assess the psychological profiles of adult male and female obese patients, as well as to verify the possible influence of their psychopathological risk and impulsivity on their body mass index (BMI) and perceived quality of life. A total of 64 obese subjects accessing a center for care of their obesity were assessed through anthropometric and psychometric measurements. All anthropometric measures in men were higher than in women, while in turn, women showed higher psychopathological symptoms. Furthermore, the symptoms of somatization and psychoticism were predictors for a higher BMI in men, but there was no effect of psychopathological symptoms on the perceived quality of life (QoL) of male subjects. Moreover, in women, somatization and attentional impulsivity were predictors for a higher BMI, whereas no correlation was found between their psychopathological risk and perceived QoL. The results of regression analysis underlined that somatization is a "core" psychopathological symptom in obese subjects regardless of their sex, which is a potential predictor for a higher BMI. The psychological difficulties of the subjects had no effect on their perceived QoL, suggesting that they find it difficult to reflect on the impact that obesity has on their life.

    from the European Organisation for the Research and Treatment of Cancer's core HRQOL questionnaire, Quality of Life Questionnaire (QLQ-C30, given its well-established domain structure.Methods: QLQ-C30 (Version 3 data were collected from 356 patients receiving palliative radiotherapy for recurrent/metastatic cancer (various primary sites. The dimensional structure of the QLQ-C30 was tested with EFA and CFA, the latter informed by the established QLQ-C30 structure and views of both patients and clinicians on which are the most relevant items. Dimensions determined by EFA or CFA were then subjected to Rasch analysis.Results: CFA results generally supported the proposed QLQ-C30 structure (comparative fit index =0.99, Tucker–Lewis index =0.99, root mean square error of approximation =0.04. EFA revealed fewer factors and some items cross-loaded on multiple factors. Further assessment of dimensionality with Rasch analysis allowed better alignment of the EFA dimensions with those detected by CFA.Conclusion: CFA was more appropriate and efficient than EFA in producing clinically interpretable results for the HSCS for a proposed new cancer-specific MAUI. Our findings suggest that CFA should be recommended generally when deriving a preference-based measure from a HRQOL measure that has an established domain structure.Keywords: multi attribute utility instrument, health state classification system, confirmatory factor analysis, exploratory factor analysis, European Organisation for the Research and Treatment of Cancer QLQ-C30

    Abstract The prevalence of cognitive impairment and orthostatic hypotension (OH) increases with age, but the results of studies that assessed possible associations between them are inconsistent. The aim of this study is to assess possible associations between cognitive impairment and OH in patients ≥65 years of age who underwent a comprehensive geriatric assessment. A retrospective analysis was conducted of the computerized medical records of the study population from 2005 to 2013. Data collected included blood pressure measurements that enabled the calculation of OH, results of the mini-mental state examination (MMSE), results of the Montreal cognitive assessment (MoCA) test, and cognitive diagnoses that were determined over the course of the assessment. The rate of OH in the study population of 571 adults was 32.1%. The mean MMSE score was 22.5 ± 5.2 among participants with OH and 21.6 ± 5.8 among those without OH (P = 0.09). The absence of a significant association between OH and MMSE remained after adjusting the MMSE score for age and education level. The mean MoCA score was 16.4 ± 5.0 among participants with OH and 16.4 ± 4.8 among those without (P = 0.33). The prevalence of OH was 39% among participants without cognitive impairment, 28.9% among those with mild cognitive impairment (MCI), and 30.6% among those with dementia (P = 0.13). There was no association between OH and cognitive impairment in adults who underwent a comprehensive geriatric assessment. PMID:27442658

    Salivary α-amylase (sAA) activity alternations are observed in major depressive disorder (MDD) being associated with depression severity and its specific psychopathological dimensions with anxiety being attributed to distress. No data is available on sAA in MDD according to Hamilton Rating Scale for Depression (HAMD-17) and State-Trait Anxiety Inventory (STAI). The exploratory study examines whether and to what extent baseline sAA level is interrelated to the psychopathological features including severity of symptoms and specific psychopathological dimensions. The basal, non-stimulated sAA activity was studied in 20 non-late-life adult, treatment-naïve MDD patients with short-illness-duration and in 20 age- and sex-matched healthy controls along with psychometric assessments with Hamilton Rating Scale for Depression (HAMD-17) and Spielberger State-Trait Anxiety Inventory (STAI). Significantly lower ( p =0.011) sAA activity was observed in MDD as compared to controls. No significant correlations were observed between sAA activity and the total HAMD-17 score as well as with regard to the specific core depression, insomnia, anxiety and somatic HAM-D psychopathological dimensions. No significant correlations were also found between sAA and STAIX-1 and STAIX-2 scores. Low baseline sAA levels in MDD with no correlations between sAA and psychopathological features including severity of symptoms and specific psychopathological dimensions was found. Key words: Salivary alpha-amylase, major depressive disorder, Spielberger State-Trait Anxiety Inventory, Hamilton Rating Scale for Depression.

    To describe the psychological stress and quality of life experienced by women who underwent fertility treatment in Taiwan. Cross-sectional, correlational study. Recruitment was conducted and questionnaires administered at a reproductive medicine center in Chiayi City, Taiwan. Informed consent to participate was obtained from 126 women who sought fertility treatment at the center. The Chinese Fertility Problem Inventory and Fertility Quality of Life scale were used to measure participants' levels of fertility-related stress and fertility-related quality of life. Descriptive statistics, correlation, and regression analysis were used. Overall, participants reported low levels of fertility-related stress and fertility-related quality of life; however, they had relatively high levels of stress related to need for parenthood. Women who were older, had greater body mass indexes, and consumed coffee regularly had lower fertility-related quality of life. Social and relationship concerns and stress related to need for parenthood were significant predictors of low fertility-related quality of life. In a culture in which childbearing is generally an expectation and an important part of family life, women who experience infertility are at risk to experience fertility-related stress. Social support and family consultation might be offered to improve women's fertility-related quality of life.

    Full Text Available Abstract Background Because of the increasing costs and anticipated shortage of Ear Nose and Throat (ENT specialists in the care for hearing-impaired persons, an integrated care pathway that includes direct hearing aid provision was developed. While this direct pathway is still under investigation, in a survey we examined expectations and potential barriers and facilitators towards this direct pathway, of patients and professionals involved in the pathway. Methods Two study populations were assessed: members of the health professions involved in the care pathway for hearing-impaired persons (general practitioners (GPs, hearing aid dispensers, ENT-specialists and clinical audiologists and persons with hearing complaints. We developed a comprehensive semi-structured questionnaire for the professionals, regarding expectations, barriers, facilitators and conditions for implementation. We developed two questionnaires for persons with hearing complaints, both regarding evaluations and preferences, and administered them after they had experienced two key elements of the direct pathway: the triage and the hearing aid fitting. Results On average GPs and hearing aid dispensers had positive expectations towards the direct pathway, while ENT-specialists and clinical audiologists had negative expectations. Professionals stated both barriers and facilitators towards the direct pathway. Most professionals either supported implementation of the direct pathway, provided that a number of conditions were satisfied, or did not support implementation, unless roughly the same conditions were satisfied. Professionals generally agreed on which conditions need to be satisfied. Persons with hearing complaints evaluated the present referral pathway and the new direct pathway equally. Many, especially older, participants stated however that they would still visit the GP and ENT-specialist, even when this would not be necessary for reimbursement of the hearing aid, and

Material and Method: Sixteen adult patients with hypospadias were included in our study. Patients with a short urethra and penile curvature were treated in two stages (orthoplasty buccal mucosal tube urethroplasty. Buccal mucosa was taken and prepared for tube urethroplasty around a 16 French (Fr nelaton catheter and the urethral tube was introduced between the urethral meatus and glans penis. Beginning the 1st postoperative day (HBO2T was applied for 10 sessions during weekdays in 13 patients. Results: The mean age was 21 (±1.23 years and mean follow-up time was 10.1 (±2.1 months. In the group who received HBO2T postoperatively (n=13, a two-stage (orthoplasty buccal mucosal tube urethroplasty procedure was performed in 6 (46%, and the mean length of graft was 5.4 (±1.23 cm. In this group of 13 the success rate without any additional manipulations (urethrotomy intern, fistula repair was 54% (7/13. After additional manipulations, complete healing was achieved in 11 out of 13 patients (84.6%. In the group who did not receive HBO2T postoperatively (n=3, a two-stage procedure was performed in 1 patient (33%, and the mean length of graft was 8 (±5 cm. In this group of 3, complete healing was not achieved in any of these patients as a result of the hypospadias surgery. However, after the additional manipulations, complete healing was achieved in 1 patient (33%. Discussion: Given the promising rates of surgical success, postoperative HBO2T might be considered as a supportive treatment modality for adult patients with hypospadias who undergo buccal mucosal tube urethroplasty. Randomized controlled studies are needed.

    1979-01-01

    The critical nature of siting nuclear power plants has led to increased emphasis on exploratory methods; it permits inspection of a continuous geologic section by both geologists and regulatory authorities and makes possible the preparation of a graphic log that delineates both obvious and subtle geologic features. About one of every two nuclear plant licensing efforts utilizes exploratory trenching. Many geologic hazards, such as ''capable'' faults, can be detected from trench exposures; they may otherwise remain undetected. Trenches must be judiciously located, survey-controlled, excavated safetly and adequately shored, logged in detail, and properly diagnosed. Useful techniques of trench logging include thorough cleaning of the trench walls, teamwork between geologist and recorder, logging against a carefully surveyed baseline and vertical reference grid, and panoramic photography. Soils, including paleosols, and glacial and glaciofluvial deposits present some of the most difficult media to log. Trench logs must be thoroughly interpreted and correlated so that they document the geologic conditions governing suitability of the site. Age-determination techniques utilized in exploratory trenching include petrographic analyses, quartz inclusion studies, clay mineralogic analyses, and radiometric methods

    Studies describing the efficacy of TPED on shortness of recovery and improvement of postoperative quality of life are limited, especially regarding gender something that has never been reported before in the literature. The purpose of this study is to evaluate possible differences of the health-related quality of life in patients who underwent TPED for LDH in accordance with sex. Seventy-six patients diagnosed and treated with TPED for LDH with 1 year follow-up were selected and divided into two groups of equal number depending on sex. Their quality of life was evaluated by using the SF-36 before the operation, six weeks, three, six and twelve months postoperatively. A statistical analysis was conducted, in order to compare the 8 scaled scores of the SF-36 combining each time two chronological phases in the total of patients, in each group and between groups. Fifty-two (68.4%) patients were ≤63 years old, while the rest 24 (31,4%) were >63 years old (mean ±SD = 56,5 ±12,1 years). Apart from the PF domain, the scores were higher in every visit for the two groups, but the change between groups was not significant. Women had a significantly higher increase of PF score in 3 months after TPED and in the interval 6 weeks-3 months comparing with men. However, in the intervals 3 months-6 months and 3 months-12 months men presented significantly higher increase compared to women. Statistically significant improvement of the quality of life for both men and women was observed. Generally, there was no significant difference between the two groups. As regards to the physical functioning, it appears to be a significant difference which is counterpoised over time. 2. TPED for LDH does not present major differences in the improvement of quality of life regarding gender.

    Our exploratory analysis examined the association between health-related quality of life (HRQoL) (baseline and change over time) and clinical outcomes (overall survival [OS]/radiographic progression-free survival [rPFS]) in metastatic castration-resistant prostate cancer (mCRPC). HRQoL, OS and rPFS were assessed in phase III trials comparing enzalutamide with placebo in chemotherapy-naïve (PREVAIL; NCT01212991) or post-chemotherapy (AFFIRM; NCT00974311) mCRPC. HRQoL was assessed using the Functional Assessment of Cancer Therapy-Prostate (FACT-P). Multivariate analyses evaluated the prognostic significance of baseline and time-dependent scores after adjusting for treatment and clinical/demographic variables. Hazard ratios (HRs) and 95% confidence intervals (CIs) represented the hazard of rPFS or OS per minimally important difference (MID) score change in HRQoL variables. In baseline and time-dependent multivariate analyses, OS was independently associated with multiple HRQoL measures across both studies. In time-dependent analyses, a 10-point (upper bound of MID range) increase (improvement) in FACT-P total score was associated with reductions in mortality risk of 19% in AFFIRM (HR 0.81 [95% CI 0.78-0.84]) and 21% in PREVAIL (HR 0.79 [0.76-0.83]). For baseline analyses, a 10-point increase in FACT-P total score was associated with reductions in mortality risk of 12% (HR 0.88 [0.84-0.93]) and 10% (HR 0.90 [0.86-0.95]) in AFFIRM and PREVAIL, respectively. rPFS was associated with a subset of HRQoL domains in both studies. Several baseline HRQoL domains were prognostic for rPFS and OS in patients with mCRPC, and this association was maintained during treatment, indicating that changes in HRQoL are informative for patients' expected survival.

    Background Multi attribute utility instruments (MAUIs) are preference-based measures that comprise a health state classification system (HSCS) and a scoring algorithm that assigns a utility value to each health state in the HSCS. When developing a MAUI from a health-related quality of life (HRQOL) questionnaire, first a HSCS must be derived. This typically involves selecting a subset of domains and items because HRQOL questionnaires typically have too many items to be amendable to the valuation task required to develop the scoring algorithm for a MAUI. Currently, exploratory factor analysis (EFA) followed by Rasch analysis is recommended for deriving a MAUI from a HRQOL measure. Aim To determine whether confirmatory factor analysis (CFA) is more appropriate and efficient than EFA to derive a HSCS from the European Organisation for the Research and Treatment of Cancer’s core HRQOL questionnaire, Quality of Life Questionnaire (QLQ-C30), given its well-established domain structure. Methods QLQ-C30 (Version 3) data were collected from 356 patients receiving palliative radiotherapy for recurrent/metastatic cancer (various primary sites). The dimensional structure of the QLQ-C30 was tested with EFA and CFA, the latter informed by the established QLQ-C30 structure and views of both patients and clinicians on which are the most relevant items. Dimensions determined by EFA or CFA were then subjected to Rasch analysis. Results CFA results generally supported the proposed QLQ-C30 structure (comparative fit index =0.99, Tucker–Lewis index =0.99, root mean square error of approximation =0.04). EFA revealed fewer factors and some items cross-loaded on multiple factors. Further assessment of dimensionality with Rasch analysis allowed better alignment of the EFA dimensions with those detected by CFA. Conclusion CFA was more appropriate and efficient than EFA in producing clinically interpretable results for the HSCS for a proposed new cancer-specific MAUI. Our findings suggest

    Full Text Available Background: N-acetyl cysteine (NAC was proposed as an adjuvant to clomiphene citratefor ovulation induction in patients with polycystic ovary syndrome (PCOS without clomiphene citrate resistance. Objective: To evaluate the effect of NAC on pregnancy rate in PCOS patients who were candidates for intrauterine insemination. Materials and Methods: In this randomized clinical trial 97 PCOS women aged 18-38 years were enrolled in two groups, randomly. For the case group (n=49, NAC (1.2 gr+ clomiphene citrate (100 mg + letrozole (5mg were prescribed Daily from the third day of menstruation cycle for five days. The control group (n=48 had the same drug regimen without NAC. In order to follicular development, GONALF was injected on days of 7-11 menstrual cycles in all participants. When the follicle size was 18mm or more, HCG (10000 IU was injected intramuscular and the intrauterine insemination was performed after 34-36 hr. Results: There were not significant differences between study groups regarding mean endometrial thickness (p=0.14, mean number of mature follicles (p=0.20 and the pregnancy rate (p=0.09. Conclusion: NAC is ineffective in inducing or augmenting ovulation in PCOS patients who were candidates for intrauterine insemination and cannot be recommended as an adjuvant to CC in such patients.

    Vaginal carcinoma is a rare gynecological malignancy that is usually treated by radiation therapy and/or surgery combined with chemotherapy. Here, we report a case of invasive vaginal carcinoma in a young woman who underwent fertility-sparing treatment involving neoadjuvant chemotherapy and conservative surgery. A 36-year-old non-parous woman had a solid tumor in the vagina. Positron emission tomography/computed tomography showed a tumor in the vagina with high FDG uptake (SUV = 17.33) but no metastatic lesions. The patient was diagnosed with vaginal squamous cell carcinoma, FIGO stage I, T1N0M0. Because she wished to retain her fertility, neoadjuvant chemotherapy consisting of irinotecan hydrochloride and nedaplatin was initiated. After four courses of chemotherapy, partial vaginectomy was carried out and the pathological diagnosis of the residual lesion was VAIN 3. Following two further courses of the same chemotherapy, she obtained complete response, and has shown no evidence of disease for 14 months. © 2014 The Authors.

    Full Text Available According to the forecasts of the Central Statistical Office of Poland, in 2030 people at the age of 65 and older will account for 23.8%, i.e. their number will amount to approx. 8.5 m people. Geriatric rheumatic patients more often decide to undergo surgical joint replacement. According to the National Health Fund, the number of joint replacement services provided in 2014 increased by 93%, as compared to 2005. Improving the physical performance of this constantly expanding group of patients requires taking into account many factors to raise their functional status, reduce the risk of falling, teach rules of proper functioning with an artificial joint and encourage unassisted physical activity. Restoring fitness and independence is a difficult but necessary task due to an increasing number of seniors with replaced joint.

    Citrus aurantium is rich in flavonoids, which may prevent osteosarcoma progression, but its related molecular mechanism remains unclear. Flavonoids were extracted from C. aurantium and purified by reparative HPLC. Each fraction was identified by using electrospray ionisation mass spectrometry (ESI-MS). Three main components (naringin, naringenin, and hesperetin) were isolated from C. aurantium. Naringenin inhibited the growth of MG-63 cells, whereas naringin and hesperetin had no inhibitory f...

    Purpose: To evaluate the location and timing of initial recurrence in patients with diffuse large B-cell lymphoma (DLBCL) who subsequently underwent high-dose chemotherapy with autologous stem cell transplant (HDC/ASCT), to direct approaches for disease surveillance, elucidate the patterns of failure of contemporary treatment strategies, and guide adjuvant treatment decisions. Methods and Materials: We analyzed consecutive patients with DLBCL who underwent HDC/ASCT between May 1992 and March 2014 at our institution. Of the 187 evaluable patients, 8 had incomplete data, and 79 underwent HDC/ASCT as a component of initial treatment for de novo or refractory DLBCL and were excluded from further analysis. Results: The median age was 50.8 years; the median time to relapse was 1.3 years. Patients were segregated according to the initial stage at diagnosis, with early stage (ES) defined as stage I/II and advanced stage (AS) defined as stage III/IV. In total, 40.4% of the ES and 75.5% of the AS patients relapsed in sites of initial disease; 68.4% of those with ES disease and 75.0% of those with AS disease relapsed in sites of initial disease only. Extranodal relapses were common (44.7% in ES and 35.9% in AS) and occurred in a variety of organs, although gastrointestinal tract/liver (n=12) was most frequent. Conclusions: Most patients with DLBCL who relapse and subsequently undergo HDC/ASCT initially recur in the previously involved disease site(s). Time to recurrence is brief, suggesting that frequency of screening is most justifiably greatest in the early posttherapy years. © 2016 Elsevier Inc.

    Duncan, D.R.

    1985-10-01

    An estimate of expected corrosion degradation during the 100-year design life of the Exploratory Shaft (ES) is presented. The basis for the estimate is a brief literature survey of corrosion data, in addition to data taken by the Basalt Waste Isolation Project. The scope of the study is expected corrosion environment of the ES, the corrosion modes of general corrosion, pitting and crevice corrosion, dissimilar metal corrosion, and environmentally assisted cracking. The expected internal and external environment of the shaft liner is described in detail and estimated effects of each corrosion mode are given. The maximum amount of general corrosion degradation was estimated to be 70 mils at the exterior and 48 mils at the interior, at the shaft bottom. Corrosion at welds or mechanical joints could be significant, dependent on design. After a final determination of corrosion allowance has been established by the project it will be added to the design criteria. 10 refs., 6 figs., 5 tabs

    The aim of the investigation was the completion of missing geological, hydrogeological and rock-mechanical data about a suitable site for the intended Nagra rock laboratory at Grimsel. To this aim, 6 horizontal boreholes of 100 m length and 86 mm diameter were drilled. The cores, extracted practically without loss, and mechanical data for the main investigation was an extensive evaluation of the lithographic discontinuities and anisotropies, because they are the main determinant of the hydrogeological conditions of the locality. The area is dominated by granites and granodiorite which are of variable biotite content, lamprophyres and aplites. The largest part of the investigated mountain region consists of compact unclefted rock. 478 of the 600 bore meters, i.e. about 80 % of the drilled mountain, have no open clefts. Only 22 of the 600 bore meters (3.6 %0 contain more than five clefts per meter, at which the open clefts in the boreholes SB1 and SB5 appear more frequently. At the remaining exploratory boreholes in 90 % of the mountain ther are no open clefts. 15 refs., 52 figs., 15 tabs

    Full Text Available Aim: The aim of this study was to review 10 years of experience in the management of children with acute intestinal conditions requiring exploratory laparotomy. Patients and Methods : This retrospective study included 334 children (244 boys and 90 girls who underwent laparotomy for acute intestinal conditions between Jan 1, 2000 to Dec 31, 2009. Patients were grouped into two categories: group A (n = 44 included patients who needed laparotomy with terminal ileostomy and group B (n = 290 included patients who needed laparotomy without terminal ileostomy. We excluded neonates and patients with jejunoileal and colonic atresias, anorectal malformations, congenital pouch colon, neonatal necrotising enterocolitis, Hirschsprung′s disease, appendicitis, abdominal trauma and gastrointestinal tumours. Results : During the last 10 years, 334 laparotomies were performed in children under 12 years: 59.88% for intestinal obstruction and 40.11% for perforation peritonitis. Causes in order of frequency were: ileal perforations 34.13%; intussusceptions 26.34%; Meckel′s obstruction 10.17%; congenital bands and malrotation 6.88%; postoperative adhesions 5.98%; miscellaneous peritonitis 5.68%; miscellaneous intestinal obstructions 4.79%; abdominal tuberculosis 4.19% and roundworm intestinal obstruction 1.79%. Ileostomy closures (n = 39 was tolerated well by all except one. The mortalities were 28 (8.38% in group B and 6 (1.79% in group A. Conclusions: The need for re-exploration not only increases the morbidity but also increases mortality as well. Diverting temporary ileostomy adds little cumulative morbidity to the primary operation and is a safe option for diversion in selected cases. The best way to further reduce the mortality is to create ileostomy at first operation.

    Full Text Available Our goal was to investigate the cortical thickness and subcortical volume in subjects with craniocervical dystonia and its subgroups.We studied 49 subjects, 17 with cervical dystonia, 18 with blepharospasm or oromandibular dystonia, and 79 healthy controls. We performed a whole group analysis, followed by a subgroup analysis. We used Freesurfer software to measure cortical thickness, subcortical volume and to perform a primary exploratory analysis in the craniocervical dystonia group, complemented by a region of interest analysis. We also performed a secondary analysis, with data generated from Freesurfer for subgroups, corrected by false discovery rate. We then performed an exploratory generalized linear model with significant areas for the previous steps using clinical features as independent variables.The primary exploratory analysis demonstrated atrophy in visual processing regions in craniocervical dystonia. The secondary analysis demonstrated atrophy in motor, sensory, and visual regions in blepharospasm or oromandibular dystonia, as well as in limbic regions in cervical dystonia. Cervical dystonia patients also had greater cortical thickness than blepharospasm or oromandibular dystonia patients in frontal pole and medial orbitofrontal regions. Finally, we observed an association between precuneus, age of onset of dystonia and age at the MRI exam, in craniocervical dystonia; between motor and limbic regions and age at the exam, clinical score and time on botulinum toxin in cervical dystonia and sensory regions and age of onset and time on botulinum toxin in blepharospasm or oromandibular dystonia.We detected involvement of visual processing regions in craniocervical dystonia, and a pattern of involvement in cervical dystonia and blepharospasm or oromandibular dystonia, including motor, sensory and limbic areas. We also showed an association of cortical thickness atrophy and younger onset age, older age at the MRI exam, higher clinical

  1. Exploratory shaft conceptual design report: Permian Basin

    International Nuclear Information System (INIS)

    1983-07-01

    This conceptual design report summarizes the conceptualized design for an exploratory shaft facility at a representative site in the Permian Basin locatd in the western part of Texas. Conceptualized designs for other possible locations (Paradox Basin in Utah and Gulf Interior Region salt domes in Louisiana and Mississippi) are summarized in separate reports. The purpose of the exploratory shaft facility is to provide access to the reference repository horizon to permit in situ testing of the salt. The in situ testing is necessary to verify repository salt design parameters, evaluate isotropy and homogeneity of the salt, and provide a demonstration of the constructability and confirmation of the design to gain access to the repository. The fundamental purpose of this conceptual design report is to assure the feasibility of the exploratory shaft project and to develop a reliable cost estimate and realistic schedule. Because a site has not been selected and site-specific subsurface data are not available, it has been necessary to make certain assumptions in order to develop a conceptual design for an exploratory shaft facility in salt. As more definitive information becomes available to support the design process, adjustments in the projected schedule and estimated costs will be required

    The physiology of the nonlactating human breast likely plays a key role in factors that contribute to the etiology of breast cancer and other breast conditions. Although there has been extensive research into the physiology of lactation, few reports explore the physiology of the resting mammary gland, including mechanisms by which compounds such as hormones, drugs, and potential carcinogens enter the breast ducts. The purpose of this study was to explore transport of exogenous drugs into ductal fluid in nonlactating women and determine if their concentrations in the fluid are similar to those observed in the breast milk of lactating women. We selected two compounds that have been well characterized during lactation, caffeine and cimetidine. Caffeine passively diffuses into breast milk, but cimetidine is actively transported and concentrated in breast milk. After ingestion of caffeine and cimetidine, 14 nonlactating subjects had blood drawn and underwent ductal lavage at five time points over 12 h to measure drug levels in the fluid and blood. The concentrations of both caffeine and cimetidine in lavage fluid were substantially less than those observed in breast milk. Our results support recent evidence that the cimetidine transporter is not expressed in the nonlactating mammary gland, and highlight intriguing differences in the physiology and molecular transport of the lactating and nonlactating breast. The findings of this exploratory study warrant further exploration into the physiology of the nonlactating mammary gland to elucidate factors involved in disease initiation and progression.

    To assess any survival advantage in patients with incurable gastric cancer who had undergone resection, bypass or exploratory surgery. In nonresectable patients with pain, the effect of celiac plexus neurolysis was assessed. We retrospectively analysed data of 330 patients, operated between 1992 and 2006. The patients were followed until death or last examination. Incurable gastric cancer was defined as TNM stage IV disease: locally advanced (LA), with solitary distant metastasis (SM) or with multiple metastases and/or peritoneal carcinomatosis (MMC). The patients were divided into these 3 groups. Their postoperative survival was calculated and compared in relation to the surgical technique used. Factors which influenced mortality and survival were identified. 131 patients (39.7%) had locally LA cancer, 98 (29.7%) SM, and 101 (30.6%) belonged to the MMC group. The surgical procedures included 138 (41.8%) exploratory laparotomies, 84 (25.5%) bypass procedures and 108 (32.7%) resections. Thirty-three (10%) unresectable patients with pain underwent celiac plexus neurolysis. The mean survival was 21.8 months after resections, 7 months after by-passes and 4.8 after exploratory laparotomies (p = 0.0001). It was 14.57 months (p=0.001) in the LA group, 12.53 (p = 0.005) in the SM group, and 5.2 in the MMC group. Survival was shorter in patients with preoperative weight loss of more than 20 kg (3.2 months, p 0.05), while significantly increased mortality occurred in patients with weight loss of over 20 kg (32%, p=0.03). Celiac plexus neurolysis was immediately effective in 30 out of 33 (91%) patients (p=0.0001), while 3 months later it was still effective in 15 (45.5%) patients (p=0.08). Resections are suggested in the LA and SM groups, and neurolysis in all nonresected patients with pain.

    Full Text Available OBJECTIVE: Compare pattern of exploratory eye movements during visual scanning of the Rorschach and TAT test cards in people with schizophrenia and controls. METHOD: 10 participants with schizophrenia and 10 controls matched by age, schooling and intellectual level participated in the study. Severity of symptoms was evaluated with the Positive and Negative Syndrome Scale. Test cards were divided into three groups: TAT cards with scenes content, TAT cards with interaction content (TAT-faces, and Rorschach cards with abstract images. Eye movements were analyzed for: total number, duration and location of fixation; and length of saccadic movements. RESULTS: Different pattern of eye movement was found, with schizophrenia participants showing lower number of fixations but longer fixation duration in Rorschach cards and TAT-faces. The biggest difference was observed in Rorschach, followed by TAT-faces and TAT-scene cards. CONCLUSIONS: Results suggest alteration in visual exploration mechanisms possibly related to integration of abstract visual information.OBJETIVO: Comparar o padrão do movimento ocular durante a inspeção dos cartões dos testes projetivos Rorschach e TAT em pessoas com esquizofrenia e controles.

    Full Text Available ABSTRACT CONTEXT AND OBJECTIVE: University students are generally at the typical age of onset of mental disorders that may affect their academic performance. We aimed to characterize the university students attended by psychiatrists at the students’ mental health service (SAPPE and to compare their academic performance with that of non-patient students. DESIGN AND SETTING: Cross-sectional study based on review of medical files and survey of academic data at a Brazilian public university. METHODS: Files of 1,237 students attended by psychiatrists at SAPPE from 2004 to 2011 were reviewed. Their academic performance coefficient (APC and status as of July 2015 were compared to those of a control group of 2,579 non-patient students matched by gender, course and year of enrolment. RESULTS: 37% of the patients had had psychiatric treatment and 4.5% had made suicide attempts before being attended at SAPPE. Depression (39.1% and anxiety disorders/phobias (33.2% were the most frequent diagnoses. Severe mental disorders such as psychotic disorders (3.7% and bipolar disorder (1.9% were less frequent. Compared with non-patients, the mean APC among the undergraduate patients was slightly lower (0.63; standard deviation, SD: 0.26; versus 0.64; SD: 0.28; P = 0.025, but their course completion rates were higher and course abandonment rates were lower. Regarding postgraduate students, patients and non-patients had similar completion rates, but patients had greater incidence of discharge for poor performance and lower dropout rates. CONCLUSION: Despite the inclusion of socially vulnerable people with severe mental disorders, the group of patients had similar academic performance, and in some aspects better, than, that of non-patients.

    The aim of this study was to investigate disability impact in patients and cost to the families of patients who have had complications of transvaginal prolapse mesh kits and underwent surgical revision. Patients who developed complications of transvaginal mesh kits for prolapse and who had undergone vaginal prolapse mesh surgical revision/removal in 2009 to 2014 at a single institution were identified by Current Procedural Terminology codes. The group was invited to complete a phone survey pertaining to the initial vaginal mesh used for prolapse surgery utilizing Sheehan Disability Scale (scale 0-10) and Years of life Lived with Disability (YLDs) questionnaires. The data collected were used to estimate the disability and cost analysis. We used our data to estimate the economic and quality-of-life impact of vaginal mesh complications on patients in the United States RESULTS: Sixty-two patients (62/198 [31.2%]) were consented to participate and completed the questionnaires by phone. Extremely disabled patients were 18 (29%) of 62 of whole cases, and 5 (8%) of 62 reported that they had no disability after vaginal mesh surgery. The median for overall disability score after vaginal mesh procedure was 8 (which reflects marked disability on a scale of 0-10). The majority of patients missed a median of 12 months of their school or work because of their mesh complications. Thirty-seven (59.6%) of 62 did not improve after mesh removal. Twenty-one (33.9%) of 62 stated that their family income dropped because of productivity loss related to mesh complications. The mean time between vaginal mesh surgery and mesh removal procedure was 4.7 years. Sheehan Disability Scale scores are significantly correlated with YLDs outcomes. Patients' overall disability score showed a significant correlation with YLDs scores (P mesh for prolapse reduction complications had a sustained disability impact that continued despite mesh removal. Likewise, the complications were associated with

    The organization of rodent exploratory behavior appears to depend on self-movement cue processing. As of yet, however, no studies have directly examined the vestibular system's contribution to the organization of exploratory movement. The current study sequentially segmented open field behavior into progressions and stops in order to characterize differences in movement organization between control and otoconia-deficient tilted mice under conditions with and without access to visual cues. Under completely dark conditions, tilted mice exhibited similar distance traveled and stop times overall, but had significantly more circuitous progressions, larger changes in heading between progressions, and less stable clustering of home bases, relative to control mice. In light conditions, control and tilted mice were similar on all measures except for the change in heading between progressions. This pattern of results is consistent with otoconia-deficient tilted mice using visual cues to compensate for impaired self-movement cue processing. This work provides the first empirical evidence that signals from the otolithic organs mediate the organization of exploratory behavior, based on a novel assessment of spatial orientation.

    Health services research of Latinos with limited English proficiency (LEP) have largely focused on studying disparities related to patient-provider communication. Less is known about their non-provider interactions such as those with patient registration systems and clinic front office staff; these interactions precede the encounter with providers and may shape how comfortable patients feel about their overall health services experience. This study explored Latino patients with LEP experiences with, and expectations for, interactions with patient registration systems and front office staff. We conducted 20 in-depth interviews with Latinos with LEP (≥ 18 years of age) who seek health services in the Piedmont Triad region, North Carolina. We analyzed participants' quotes and identified themes by using a constant comparison method. This research was conducted by a community-academic partnership; partners were engaged in study design, instrument development, recruitment, data analysis, and manuscript writing. Qualitative analysis allowed us to identify the following recurring themes: 1) inconsistent registration of multiple surnames may contribute to patient misidentification errors and delays in receiving health care; 2) lack of Spanish language services in front office medical settings negatively affect care coordination and satisfaction with health care; and 3) perceived discrimination generates patients' mistrust in front office staff and discomfort with services. Latino patients in North Carolina experience health services barriers unique to their LEP background. Participants identified ways in which the lack of cultural and linguistic competence of front office staff negatively affect their experiences seeking health services. Healthcare organizations need to support their staff to encourage patient-centered principles.

    Methylentetrahydrofolate reductase (MTHFR) plays a major role in folate metabolism and consequently could be an important factor for the efficacy of a treatment with 5-fluorouracil. Our aim was to evaluate the prognostic and predictive value of two well characterized constitutional MTHFR gene polymorphisms for primarily resected and neoadjuvantly treated esophagogastric adenocarcinomas. 569 patients from two centers were analyzed (gastric cancer: 218, carcinoma of the esophagogastric junction (AEG II, III): 208 and esophagus (AEG I): 143). 369 patients received neoadjuvant chemotherapy followed by surgery, 200 patients were resected without preoperative treatment. The MTHFR C677T and A1298C polymorphisms were determined in DNA from peripheral blood lymphozytes. Associations with prognosis, response and clinicopathological factors were analyzed retrospectively within a prospective database (chi-square, log-rank, cox regression). Only the MTHFR A1298C polymorphisms had prognostic relevance in neoadjuvantly treated patients but it was not a predictor for response to neoadjuvant chemotherapy. The AC genotype of the MTHFR A1298C polymorphisms was significantly associated with worse outcome (p = 0.02, HR 1.47 (1.06-2.04). If neoadjuvantly treated patients were analyzed based on their tumor localization, the AC genotype of the MTHFR A1298C polymorphisms was a significant negative prognostic factor in patients with gastric cancer according to UICC 6 th edition (gastric cancer including AEG type II, III: HR 2.0, 95% CI 1.3-2.0, p = 0.001) and 7 th edition (gastric cancer without AEG II, III: HR 2.8, 95% CI 1.5-5.7, p = 0.003), not for AEG I. For both definitions of gastric cancer the AC genotype was confirmed as an independent negative prognostic factor in cox regression analysis. In primarily resected patients neither the MTHFR A1298C nor the MTHFR C677T polymorphisms had prognostic impact. The MTHFR A1298C polymorphisms was an independent prognostic factor in patients

    Electroconvulsive therapy (ECT) is the most effective and rapid treatment for severe major depressive disorder (MDD) in elderly patients. The mechanism of ECT is unclear, and studies on ECT in elderly MDD patients by resting-state functional magnetic resonance imaging are rare. Thirteen elderly MDD patients were scanned before and after ECT using a 3.0T MRI scanner. Regional homogeneity (ReHo) and amplitude of low-frequency fluctuations (ALFF) were processed to compare resting-state function before and after treatment. Depression and anxiety symptoms of all patients abated after ECT. Decreased ReHo values in the bilateral superior frontal gyrus (SFG) were observed after ECT, and the values of right SFG significantly correlated with an altered Hamilton depression rating scale score. Increased ALFF values in the left middle frontal gyrus, right middle frontal gyrus, orbital part, and decreased ALFF values in the left midcingulate area, left precentral gyrus, right SFG/middle frontal gyrus after ECT were also observed. These results support the hypothesis that ECT may affect the regional resting state brain function in geriatric MDD patients. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    There is increasing evidence linking vitamin D deficiency to both susceptibility to, and severity of, multiple sclerosis (MS). Patients with the clinically isolated syndrome represent the initial presentation of a demyelinating disorder, and those with asymptomatic lesions on magnetic resonance imaging (MRI) are at risk of progression to clinically definite MS. The aims of this study are to examine the immunologic effects of vitamin D in both healthy individuals and in patients with clinically isolated syndrome, and in the latter group the effects on disease progression assessed by MRI and clinical measures.

    Tapering of anti-tumour necrosis factor (TNF) therapy appears feasible, safe and effective in selected patients with rheumatoid arthritis (RA). Depression is highly prevalent in RA and may impact on flare incidence through various mechanisms. This study aims to investigate if psychological states predict flare in patients' dose tapering their anti-TNF therapy. This study is a post-hoc analysis of the Optimizing TNF Tapering in RA trial, a multicentre, randomised, open-label study investigating anti-TNF tapering in RA patients with sustained low disease activity. Patient-reported outcomes (Health Assessment Questionnaire, EuroQol 5-dimension scale, Functional Assessment of Chronic Illness Therapy fatigue scale (FACIT-F), 36-Item Short Form Survey (SF-36)) were collected at baseline. The primary outcome was flare, defined as an increase in 28-joint count Disease Activity Score (DAS28) ≥0.6 and ≥1 swollen joint. Discrete-time survival models were used to identify patient-reported outcomes that predict flare. Ninety-seven patients were randomised to taper their anti-TNF dose by either 33% or 66%. Forty-one patients flared. Higher baseline DAS28 score was associated with flare (adjusted HR 1.96 (95% CI 1.18 to 3.24), p=0.01). Disability (SF-36 physical component score), fatigue (FACIT-F) and mental health (SF-36 mental health subscale (MH)) predicted flare in unadjusted models. In multivariate analyses, only SF-36 MH remained a statistically significant predictor of flare (adjusted HR per 10 units 0.74 (95% CI 0.60 to 0.93), p=0.01). Baseline DAS28 and mental health status are independently associated with flare in patients who taper their anti-TNF therapy. Fatigue and function also associate with flare but the effect disappears when adjusting for confounders. Given these findings, mental health and functional status should be considered in anti-TNF tapering decisions in order to optimise the likelihood of success.

    Lumbar stabilization exercise programs (LSEP) produce positive effects on clinical outcomes, but the underlying mechanisms remain relatively unexplored. Psychological and neuromuscular mechanisms can be involved, such as a better activation of the lumbar multifidus, which represents one possibility. To determine the following: (1) the effect of an LSEP on lumbar multifidus muscle thickness and activation, as measured with rehabilitative ultrasound imaging (RUSI), in patients with low back pain (LBP); (2) the correlation between RUSI measures and any change in clinical outcomes following the LSEP; and (3) the reliability of RUSI measures in control subjects over 8 weeks. One-arm clinical trial with healthy subjects as a control group; reliability study. LSEP delivered in a clinical setting; outcomes measured in a laboratory setting. A total of 34 patients with nonacute LBP and 28 healthy control subjects. Outcomes were measured before and after an 8-week LSEP in patients with LBP, and at the same time interval (without treatment, to assess reliability) in control subjects. Pain numeric rating scale, Oswestry Disability Index (function), as well as RUSI measures for the lumbar multifidus (LM) muscles at 3 vertebral levels (L5-S1, L4-5, and L3-4) during rest (static) and dynamic contractions (percent thickness change). Patients did not show systematic changes in RUSI measures relative to controls, even though RUSI impairments were observed at baseline (dynamic measure at L5-S1) and even though patients had significant improvements in pain and disability. Correlational analyses with these clinical outcomes suggested that patients had reduced muscle thickness at baseline that was associated with a greater reduction in disability following LSEP; however, LM activation measured at baseline showed the opposite. Static RUSI measures showed excellent reliability at the L4-5 and L3-4 levels, whereas dynamic measures were not reliable. Patients showed less muscle activation

    The aim of this study was to identify subsets of patients with fibromyalgia with similar symptom profiles using the Outcome Measures in Rheumatology (OMERACT) core symptom domains. Female patients with a diagnosis of fibromyalgia and currently meeting fibromyalgia research survey criteria completed the Brief Pain Inventory, the 30-item Profile of Mood States, the Medical Outcomes Sleep Scale, the Multidimensional Fatigue Inventory, the Multiple Ability Self-Report Questionnaire, the Fibromyalgia Impact Questionnaire-Revised (FIQ-R) and the Short Form-36 between 1 June 2011 and 31 October 2011. Hierarchical agglomerative clustering was used to identify subgroups of patients with similar symptom profiles. To validate the results from this sample, hierarchical agglomerative clustering was repeated in an external sample of female patients with fibromyalgia with similar inclusion criteria. A total of 581 females with a mean age of 55.1 (range, 20.1 to 90.2) years were included. A four-cluster solution best fit the data, and each clustering variable differed significantly (P FIQ-R total scores (P = 0.0004)). In our study, we incorporated core OMERACT symptom domains, which allowed for clustering based on a comprehensive symptom profile. Although our exploratory cluster solution needs confirmation in a longitudinal study, this approach could provide a rationale to support the study of individualized clinical evaluation and intervention.

    Full Text Available BACKGROUND: Infection by the pandemic influenza A (H1N1/09 virus resulted in significant pathology among specific ethnic groups worldwide. Natural Killer (NK cells are important in early innate immune responses to viral infections. Activation of NK cells, in part, depend on killer-cell immunoglobulin-like receptors (KIR and HLA class I ligand interactions. To study factors involved in NK cell dysfunction in overactive immune responses to H1N1 infection, KIR3DL1/S1 and KIR2DL2/L3 allotypes and cognate HLA ligands of H1N1/09 intensive-care unit (ICU patients were determined. METHODOLOGY AND FINDINGS: KIR3DL1/S1, KIR2DL2/L3, and HLA -B and -C of 51 H1N1/09 ICU patients and 105 H1N1-negative subjects (St. Theresa Point, Manitoba were characterized. We detected an increase of 3DL1 ligand-negative pairs (3DL1/S1(+ Bw6(+ Bw4(-, and a lack of 2DL1 HLA-C2 ligands, among ICU patients. They were also significantly enriched for 2DL2/L3 ligand-positive pairs (PVA, P=0.024, Pc=0.047; Odds Ratio:2.563, CI95%:1.109-5.923, 3DL1*00101 (Ab>VA, PSTh, P=0.034, Pc=0.268, and 3DL1*029 (Ab>STh, P=0.039, Pc=0.301.

    Health technology appraisal agencies often rely on cost-effectiveness analyses to inform coverage decisions for new treatments. These assessments, however, frequently measure a treatment's value from the payer's perspective, and may not capture value generated from reduced caregiving costs, increased productivity, value based on patient risk preferences, option value or the insurance value to non-patients. To examine how using a broader societal perspective of treatment value affects cost-effectiveness estimates, this case study analyzed the net monetary benefit (NMB) of second-line nivolumab treatment of patients with squamous non-small cell lung cancer (NSCLC) in Canada. The comparator was treatment with docetaxel. NMB was measured from three perspectives: (i) traditional payer, (ii) traditional societal and (iii) broad societal. Nivolumab was more effective (increased quality-adjusted life years by 0.66 versus docetaxel), but also increased costs by $100,168 CAD. When valuing a quality-adjusted life year at $150,000, the net monetary benefit from the payer perspective suggested that costs modestly exceed benefits (NMB: -$1031). Adopting a societal perspective, however, nivolumab's benefits outweighed its costs (NMB: +$6752 and +$91,084 from the traditional and broad societal perspectives, respectively). Broadening cost-effectiveness analysis beyond the traditional payer perspective had a significant impact on the result and should be considered in order to capture all treatment benefits and costs of societal relevance.

    Little is known regarding how diabetic men with erectile dysfunction (ED) differ from the general population of impotent men. The primary objective of this study was to compare disease-specific health-related quality of life (HRQOL) and severity of ED in impotent men with and without diabetes. Validated functional and HRQOL questionnaires (including the International Index of Erectile Function, the Sexual Self-Efficacy Scale, and the Psychological Impact of Erectile Dysfunction scales) were administered to patients in an ED disease registry. Men with ED and a history of diabetes (n = 20) were compared with men with ED and no history of diabetes (n = 90) at baseline and at the 12-month follow-up. Diabetic impotent men reported worse erectile function and intercourse satisfaction at baseline, and ED had a greater impact on their emotional life. Diabetic men with ED had significantly different trends over time in the Erectile Function (P Emotional Life-Psychological Impact domain (P < 0.067). Impotent men with diabetes present with worse ED than nondiabetic men with ED, resulting in worse disease-specific HRQOL in the diabetic men. Although diabetic patients initially respond well to ED treatment, responses do not appear to be durable over time. Therefore, clinicians must provide longer-term follow-up when treating ED in diabetic patients.

    Patients with obstructive sleep apnoea hypopnoea syndrome (OSA) might have varying degrees of laryngopharyngeal mechanical hyposensitivity that might impair the brain's capacity to prevent airway collapse during sleep. However, this knowledge about sensory compromises in OSA comes from studies performed using methods with little evidence of their validity. Hence, the purpose of this study is to assess the reliability and accuracy of the measurement of laryngopharyngeal mechanosensitivity in patients with OSA using a recently developed laryngopharyngeal endoscopic esthesiometer and rangefinder (LPEER). The study will be prospective and double blinded, with a randomised crossover assignment of raters performing the sensory tests. Subjects will be recruited from patients with suspected OSA referred for baseline polysomnography to a university hospital sleep laboratory. Intra-rater and inter-rater reliability will be evaluated using the Bland-Altman's limits of agreement plot, the intraclass correlation coefficient, and the Pearson or Spearman correlation coefficient, depending on the distribution of the variables. Diagnostic accuracy will be evaluated plotting ROC curves using standard baseline polysomnography as a reference. The sensory threshold values ​​for patients with mild, moderate and severe OSA will be determined and compared using ANOVA or the Kruskal-Wallis test, depending on the distribution of the variables. The LPEER could be a new tool for evaluating and monitoring laryngopharyngeal sensory impairment in patients with OSA. If it is shown to be valid, it could help to increase our understanding of the pathophysiological mechanisms of this condition and potentially help in finding new therapeutic interventions for OSA. The protocol has been approved by the Institutional Review Board of Fundacion Neumologica Colombiana. The results will be disseminated through conference presentations and peer-reviewed publication.

    2015-01-01

    Background Many studies have shown that women use the Internet more often for health-related information searches than men, but we have limited knowledge about the underlying reasons. We also do not know whether and how women and men differ in their current use of the Internet for communicating with their general practitioner (GP) and in their future intention to do so (virtual patient-physician relationship). Objective This study investigates (1) gender differences in health-related information search behavior by exploring underlying emotional, motivational, attitudinal as well as cognitive variables, situational involvement, and normative influences, and different personal involvement regarding health-related information searching and (2) gender differences in the virtual patient-physician relationship. Methods Gender differences were analyzed based on an empirical online survey of 1006 randomly selected German patients. The sample was drawn from an e-panel maintained by GfK HealthCare. A total of 958 usable questionnaires were analyzed. Principal component analyses were carried out for some variables. Differences between men (517/958) and women (441/958) were analyzed using t tests and Kendall’s tau-b tests. The survey instrument was guided by several research questions and was based on existing literature. Results Women were more engaged in using the Internet for health-related information searching. Gender differences were found for the frequency of usage of various Internet channels for health-related information searches. Women used the Internet for health-related information searches to a higher degree for social motives and enjoyment and they judged the usability of the Internet medium and of the information gained by health information searches higher than men did. Women had a more positive attitude toward Web 2.0 than men did, but perceived themselves as less digitally competent. Women had a higher health and nutrition awareness and a greater

    Hypoxia is associated with resistance to chemotherapy and radiotherapy and is randomly distributed within malignancies. Characterization of changes in intratumoral hypoxic regions is possible with specially developed PET tracers such as (18)F-fluoroazomycin arabinoside ((18)F-FAZA) while tumor metabolism can be measured with 2-deoxy-2-[(18)F]fluoro-D-glucose ((18)F-FDG). The purpose of this study was to study the effects of chemotherapy on (18)F-FAZA and (18)F-FDG uptake simultaneously in non-small-cell lung cancer (NSCLC) patients At baseline and after the second chemotherapy cycle, both PET/CT with (18)F-FDG and (18)F-FAZA was performed in seven patients with metastasized NSCLC. (18)F-FAZA and (18)F-FDG scans were aligned with deformable image registration using Mirada DBx. The primary tumors were contoured, and on the (18)F-FDG scan, volumes of interest (VOI) were drawn using a 41 % adaptive threshold technique. Subsequently, the resulting VOI was transferred to the (18)F-FAZA scan. (18)F-FAZA maximum tumor-to-background (T/Bgmax) ratio and the fractional hypoxic volume (FHV) were assessed. Measurements were corrected for partial volume effects. Finally, a voxel-by-voxel analysis of the primary tumor was performed to assess regional uptake differences. In the primary tumor of all seven patients, median (18)F-FDG standard uptake value (SUVmax) decreased significantly (p = 0.03). There was no significant decrease in (18)F-FAZA uptake as measured with T/Bgmax (p = 0.24) or the FHV (p = 0.35). Additionally, volumetric voxel-by-voxel analysis showed that low hypoxic tumors did not significantly change in hypoxic status between baseline and two cycles of chemotherapy, whereas highly hypoxic tumors did. Individualized volumetric voxel-by-voxel analysis revealed that hypoxia and metabolism were not associated before and after 2 cycles of chemotherapy. Tumor hypoxia and metabolism are independent dynamic events as measured by (18)F-FAZA PET and (18)F

    Full Text Available This paper presents a powerful tool to enhance research in education: ‘exploratory portals’, supporting effective storage, sharing and exploration of large sets of research data. The workflow is the following: data are gathered by a research group; they are then classified according to a taxonomy (the one that best fits the group’s research interest; once uploaded in the portal, they can be ‘explored’ via a combination of faceted search (enriched by Boolean operators and data mining techniques. The system can thus answer in a few seconds to sophisticated user’s queries that otherwise would require hours; it can save a session’s results and materials for sharing with other scholars or for further investigation. The paper presents a case study of exploratory portal, dealing with data on (technology-based education. The portal has effectively been used by five different research groups, to run complex investigations of data about technology integration into schools.

    Full Text Available Background: Intimate partner violence (IPV is a serious public health problem, impacting more than 12 million people in the United States each year. The only know effective health care intervention is routine screening for IPV exposure; however, this intervention has been poorly adopted. Expansion of screening efforts to the community pharmacy setting provides an opportunity to have a substantial impact on the health and well-being of pharmacy patients. However, little is known about pharmacists’ knowledge, attitudes, and behaviors related to IPV.Objective: The objective of this study was to conduct an exploratory investigation of community pharmacists’ current level of knowledge, attitudes, behaviors, and intentions related to IPV and to IPV screening.Methods: A cross-sectional study using an online questionnaire was conducted. Surveys were distributed via email. Descriptive analyses of survey responses were conducted.Results: A total of 144 community pharmacists completed the survey. Results indicated most (67.4% had no IPV education/training. Participants were significantly more willing to conduct screening with targeted patients compared to all patients. (X2=129.62; df=36; p<0.0001. There was strong agreement with interest in and willingness to participate in continuing education.Conclusions: Most respondents indicated relatively low levels of IPV knowledge and training and very little current IPV screening activity. Continuing education on IPV should be considered for pharmacists to increase knowledge and awareness of IPV.

    Leprosy is an infectious disease caused by Mycobacterium leprae that affects the skin and nerves. Although curable with multidrug therapy, leprosy is complicated by acute inflammatory episodes called reactions, which are the major causes of irreversible neuropathy in leprosy that occur before, during, and even after treatment. Early diagnosis and prompt treatment of reactions reduces the risk of permanent disability. This exploratory study investigated whether urinary metabolic profiles could be identified that correlate with early signs of reversal reactions (RR). A prospective cohort of leprosy patients with and without reactions and endemic controls was recruited in Nepal. Urine-derived metabolic profiles were measured longitudinally. Thus, a conventional area of biomarker identification for leprosy was extended to non-invasive urine testing. It was found that the urinary metabolome could be used to discriminate endemic controls from untreated patients with mycobacterial disease. Moreover, metabolic signatures in the urine of patients developing RR were clearly different before RR onset compared to those at RR diagnosis. This study indicates that urinary metabolic profiles are promising host biomarkers for the detection of intra-individual changes during acute inflammation in leprosy and could contribute to early treatment and prevention of tissue damage.

    In addition to inhibiting epidermal growth factor receptor (EGFR) signaling, anti-EGFR antibodies of the IgG1 'subtype' can induce a complementary therapeutic effect through the induction of antibody-dependent cell-mediated cytotoxicity (ADCC). Glycoengineering of therapeutic antibodies increases the affinity for the Fc-gamma receptor, thereby enhancing ADCC. We investigated the changes in immune effector cells and EGFR pathway biomarkers in 44 patients with operable, advanced stage head and neck squamous cell carcinoma treated with two preoperative doses of either glycoengineered imgatuzumab (GA201; 700 or 1400 mg) or cetuximab (standard dosing) in a neoadjuvant setting with paired pre- and post-treatment tumor biopsies. Significant antitumor activity was observed with both antibodies after just two infusions. Metabolic responses were seen in 23 (59.0%) patients overall. One imgatuzumab-treated patient (700 mg) achieved a 'pathological' complete response. An immediate and sustained decrease in peripheral natural killer cells was consistently observed with the first imgatuzumab infusion but not with cetuximab. The functionality of the remaining peripheral natural killer cells was maintained. Similarly, a pronounced increase in circulating cytokines was seen following the first infusion of imgatuzumab but not cetuximab. Overall, tumor-infiltrating CD3+ cell counts increased following treatment with both antibodies. A significant increase from baseline in CD3+/perforin+ cytotoxic T cells occurred only in the 700-mg imgatuzumab group (median 95% increase, P < 0.05). The most prominent decrease of EGFR-expressing cells was recorded after treatment with imgatuzumab (700 mg, -34.6%; 1400 mg, -41.8%). The post-treatment inflammatory tumor microenvironment was strongly related to baseline tumor-infiltrating immune cell density, and baseline levels of EGFR and pERK in tumor cells most strongly predicted therapeutic response. These pharmacodynamic

    Full Text Available The aim of this study was to examine the relationship between children exploratory behaviour and the quality of structural childcare and process in preschools. The study also examined how childcare quality affects the relationship between emotional wellbeing and exploratory behaviour. The sample comprised 206 children from 40 classrooms in 20 preschools, together with their teachers. The children's age ranged between 37 and 64 months (M = 50.96, SD = 6.54. The results indicated that children cared for by more sensitive teachers engaged in more exploratory behavior. However, no moderating effect was found of teacher sensitivity on the positive relationship between exploratory behavior and wellbeing. Finally, some factors linked to the quality of structural childcare also influenced exploratory behavior, although to a lesser extent.

    2014-07-01

    Full Text Available Introduction: Non-invasive, continuous hemodynamic monitoring is entering the clinical arena. The primary objective of this study was to test the feasibility of such monitoring in a pilot sample of Emergency Department (ED stroke patients. Secondary objectives included analysis of hemodynamic variability and correlation of continuous blood pressure measurements with standard measurements. Methods: This study was a secondary analysis of 7 stroke patients from a prospectively collected data set of patients that received 2 hours of hemodynamic monitoring in the ED. Stroke patients were included if hemorrhagic or ischemic stroke was confirmed by neuroimaging, and symptom onset was within 24 hours. They were excluded for the presence of a stroke mimic or transient ischemic attack. Monitoring was performed using the Nexfin device (Edwards Lifesciences, Irvine CA. Results: The mean age of the cohort was 71 ± 17 years, 43% were male, and the mean National Institute of Health Stroke Scale (NIHSS was 6.9 ± 5.5. Two patients had hemorrhagic stroke. We obtained 42,456 hemodynamic data points, including beat-to-beat blood pressure measurements with variability of 18 mmHg and cardiac indices ranging from 1.8 to 3.6 l/min/m2. The correlation coefficient between continuous blood pressure measurements with the Nexfin device and standard ED readings was 0.83. Conclusion: This exploratory investigation revealed that continuous, noninvasive monitoring in the ED is feasible in acute stroke. Further research is currently underway to determine how such monitoring may impact outcomes in stroke or replace the need for invasive monitoring. [West J Emerg Med. 2014;15(4:–0.

    Staff shortages could harm the provision and quality of health care in Uganda, so staff retention and motivation are crucial. Understanding the impact of HIV/AIDS on staff contributes to designing appropriate retention and motivation strategies. This research aimed 'to identify the influence of HIV/AIDS on staff working in general hospitals at district level in rural areas and to explore support required and offered to deal with HIV/AIDS in the workplace'. Its results were to inform strategies to mitigate the impact of HIV/AIDS on hospital staff. A cross-sectional study with qualitative and quantitative components was implemented during two weeks in September 2005. Data were collected in two government and two faith-based private not-for-profit hospitals purposively selected in rural districts in Uganda's Central Region. Researchers interviewed 237 people using a structured questionnaire and held four focus group discussions and 44 in-depth interviews. HIV/AIDS places both physical and, to some extent, emotional demands on health workers. Eighty-six per cent of respondents reported an increased workload, with 48 per cent regularly working overtime, while 83 per cent feared infection at work, and 36 per cent reported suffering an injury in the previous year. HIV-positive staff remained in hiding, and most staff did not want to get tested as they feared stigmatization. Organizational responses were implemented haphazardly and were limited to providing protective materials and the HIV/AIDS-related services offered to patients. Although most staff felt motivated to work, not being motivated was associated with a lack of daily supervision, a lack of awareness on the availability of HIV/AIDS counselling, using antiretrovirals and working overtime. The specific hospital context influenced staff perceptions and experiences. HIV/AIDS is a crucially important contextual factor, impacting on working conditions in various ways. Therefore, organizational responses should be

    This exploratory study attempts to demonstrate the potential utility of crowdsourcing as a supplemental technique for quantifying transcribed interviews. Crowdsourcing is the harnessing of the abilities of many people to complete a specific task or a set of tasks. In this study multiple samples of crowdsourced individuals were asked to rate and select supporting quotes from two different transcripts. The findings indicate that the different crowdsourced samples produced nearly identical ratings of the transcripts, and were able to consistently select the same supporting text from the transcripts. These findings suggest that crowdsourcing, with further development, can potentially be used as a mixed method tool to offer a supplemental perspective on transcribed interviews.

    This report addresses the impact of the quality assurance practices used for the Exploratory Shaft Facility (ESF) design, and construction in licensing as part of the repository. Acceptance criteria used for evaluating the suitability of ESF QA practices are based on documents that had not been invoked for repository design or construction activities at the time of this evaluation. This report identifies the QA practices necessary for ESF design and construction licensability. A review and evaluation of QA practices for ESF design and construction resulted in the following conclusions. QA practices were found to be acceptable with a few exceptions. QA practices for construction activities were found to be insufficiently documented in implementing procedures to allow a full and effective evaluation for licensing purposes.

    Purpose. - The distance between the patient's home and a radiotherapy department may represent a hurdle for the patient and influence treatment choice. Therefore, it is necessary to check whether the geographical distribution of radiotherapy centers is in accordance with cancer incidence, taking also into account the cost of travelling to the radiotherapy department. The objective of this study is double; first, to map the current locations of radiotherapy centers across the country and second, to evaluate the observed spatial disparities with appropriate tools. Materials and methods. - A model of operational research (P-median) is used to suggest the optimal locations and allocations and to compare them with the current situation. This is an exploratory study with simple inputs. It helps to better understand the current geographical distribution of radiotherapy centers in Belgium as well as its possible limitations. Results-conclusion. - It appears that the current situation is on the average acceptable in terms of accessibility to the service and that the method presents huge potentialities for decision making so as to yield a spatial system that is both efficient and equitable.

    The modern healthcare landscape has seen the rapid emergence of techniques and devices that temporally monitor and record physiological signals. The prevalence of time-series data within the healthcare field necessitates the development of methods that can analyze the data in order to draw meaningful conclusions. Time-series behavior is notoriously difficult to intuitively understand due to its intrinsic high-dimensionality, which is compounded in the case of analyzing groups of time series collected from different patients. Our framework, which we call transition icons, renders common patterns in a visual format useful for understanding the shared behavior within groups of time series. Transition icons are adept at detecting and displaying subtle differences and similarities, e.g., between measurements taken from patients receiving different treatment strategies or stratified by demographics. We introduce various methods that collectively allow for exploratory analysis of groups of time series, while being free of distribution assumptions and including simple heuristics for parameter determination. Our technique extracts discrete transition patterns from symbolic aggregate approXimation representations, and compiles transition frequencies into a bag of patterns constructed for each group. These transition frequencies are normalized and aligned in icon form to intuitively display the underlying patterns. We demonstrate the transition icon technique for two time-series datasets-postoperative pain scores, and hip-worn accelerometer activity counts. We believe transition icons can be an important tool for researchers approaching time-series data, as they give rich and intuitive information about collective time-series behaviors.

    Full Text Available Os efeitos colaterais da radioterapia instituída para tratamento de pacientes com câncer da região de cabeça e pescoço interferem significativamente na qualidade de vida desses indivíduos. Entre esses efeitos, podem-se citar mucosite, hipossialia, ageusia, cáries por radiação, trismo e osteorradionecrose (ORN. Esta última constitui uma complicação grave e de difícil tratamento. A presente revisão da literatura objetiva enfatizar aspectos da osteorradionecrose, abordando fatores etiológicos, características clínicas e radiográficas, prevalência, tratamento e prognóstico da enfermidade. O cumprimento de medidas protocolares antes, durante e após a radioterapia de cabeça e pescoço previne e minimiza a ocorrência de complicações como a ORN. As consultas de controle após o término da radioterapia são imprescindíveis e devem ser garantidas pela conscientização do paciente sobre a importância das mediadas preventivas

    An increasing number of breast cancer patients are accessing the Internet for medical information. A survey was administered to breast cancer patients and their families attending follow-up outpatient clinics in a comprehensive cancer care center to explore their frequency of Internet use, their motivation for online activity, the type of information they sought, and the perceived impact of the information they found on the Internet on their medical care. The survey was conducted over a 4-month period. A total of 107 surveys were returned. Seventy-nine of these (74%) were from patients while 28 (26%) were from family members and friends. Thirty-four of the patient responses (43%) indicated that the patient had used the Internet to look for cancer-related information. Patients who had used the Internet to access cancer-related information were significantly younger (P = 0.007), better educated (P = 0.027), and less satisfied with the amount of treatment-related information given by caregivers than those patients who had not used the Internet to access cancer-related information (P = 0.032). The majority of patient Internet users desired more information on their cancer and its treatment (91%), looked up information that was presented to them by their clinicians (66%), researched other treatment options (63%), and obtained more information on "alternative treatments" (63%). Patient Internet users generally found the cancer-related information on the Internet to be useful, and the majority discussed Internet-derived information with their health care providers and perceived that clinicians listened to such information. However, 53% were undecided about the trustworthiness of the medical information obtained via the Internet. Internet nonusers commonly lacked Internet access (53%) or were unfamiliar with the Internet (33%), but few (13%) distrusted Internet-derived information. This exploratory study underscores the need for more research in this area, specifically

    Impaired function of prefrontal brain networks may be the source of both negative symptoms and neurocognitive problems in psychotic disorders. Whereas most antipsychotics may decrease prefrontal activation, the partial dopamine D2-receptor agonist aripiprazole is hypothesized to improve prefrontal function. This study investigated whether patients with a psychotic disorder would show stronger activation of prefrontal areas and associated regions after treatment with aripiprazole compared to risperidone treatment. In this exploratory pharmacological neuroimaging study, 24 patients were randomly assigned to either aripiprazole or risperidone. At baseline and after nine weeks treatment they underwent an interview and MRI session. Here we report on brain activation (measured with arterial spin labeling) during performance of two tasks, the Tower of London and the Wall of Faces. Aripiprazole treatment decreased activation of the middle frontal, superior frontal and occipital gyrus (ToL) and medial temporal and inferior frontal gyrus, putamen and cuneus (WoF), while activation increased after risperidone. Activation increased in the ventral anterior cingulate and posterior insula (ToL), and superior frontal, superior temporal and precentral gyrus (WoF) after aripiprazole treatment and decreased after risperidone. Both treatment groups had increased ventral insula activation (ToL) and middle temporal gyrus (WoF), and decreased occipital cortex, precuneus and caudate head activation (ToL) activation. In conclusion, patients treated with aripiprazole may need less frontal resources for planning performance and may show increased frontotemporal and frontostriatal reactivity to emotional stimuli. More research is needed to corroborate and extend these preliminary findings. Copyright © 2017 Elsevier Inc. All rights reserved.
