Does pretreatment with statins improve clinical outcome after stroke?

The unadjusted odds ratio for early discharge to home (versus late discharge or death) was 1.41 (95% CI 0.91 to 2.17) when patients on statin treatment were compared with referent stroke patients not on statins. Prognostic factors were, in general, more unfavorable among patients on statins. When this was adjusted for in a logistic regression model, the use of statins was a moderately strong but statistically nonsignificant predictor of discharge to home (multiple-adjusted odds ratio 1.42, 95% CI 0.90 to 2.22).

Does immediate breast reconstruction compromise the delivery of adjuvant chemotherapy?

Comparisons were made between 107 patients who received IBR and 113 who received mastectomy alone. Those receiving IBR were on average younger, with lower body mass index (BMI) and better prognoses. Overall complication rates were comparable (mastectomy alone: 45.1% versus IBR: 35.5%, p = 0.2). There was more return to surgery in the IBR group with 11.5% of tissue expanders requiring removal, whilst more seromas occurred in the mastectomy group. There was no significant difference in the median time to chemotherapy.

Does immediate breast reconstruction compromise the delivery of adjuvant chemotherapy?

We studied 100 asthma patients who were divided into the following four groups: patients with obstruction who were either ICS-naive (group I) or were treated with ICSs (group II); and nonobstructed patients who were either ICS-naive (group III) or were treated with ICSs (group IV). PD on the visual analog scale (VAS) was assessed during a methacholine-induced FEV(1) decrease and specifically was quantified as the VAS slope and score at an FEV(1) decrease of 5 to 20%. BHR was assessed in terms of the provocative concentration of methacholine causing a 20% fall in FEV(1) (PC(20)). Eosinophil counts in induced sputum samples also were performed. Regression analysis, univariate analysis of variance, and factor analysis were applied for statistical evaluation.

Do instrumental activities of daily living predict dementia at 1- and 2-year follow-up?

The "July effect" refers to the phenomenon of adverse impacts on patient care arising from the changeover in medical staff that takes place during this month at academic medical centres in North America. There has been some evidence supporting the presence of the July effect, including data from surgical specialties. Uniformity of care, regardless of time of year, is required for patients undergoing major cancer surgery. We therefore sought to perform a population-level assessment for the presence of a July effect in this field.

Does the Simultaneous Use of a Neuroendoscope Influence the Incidence of Ventriculoperitoneal Shunt Infection?

This study included 438 VPS procedures, 49 in which an endoscope was used (11.2%) and 389 in which an endoscope was not used (88.8%). The infection rates in these 2 main groups were calculated and compared. Subsequently, 4 new groups were created, composed of patients with a shunt inserted for the first time (groups 1A and 1B) and patients with a shunt reviewed or inserted for a second time (groups 2A and 2B). Groups 1A and 2A comprised patients in whom an endoscope was used simultaneously with VPS surgery, and groups 1B and 2B comprised patients in whom an endoscope was not used. These groups were compared to determine the infection rate.

Papillary thyroid carcinomas (PTCs) were the most frequent histological subtype (54.9 %), followed by poorly differentiated thyroid carcinoma [PDTC] (30.5 %) and follicular thyroid carcinoma [FTC](14.6 %). A genetic mutation was identified in 23 patients (28 %) and BRAF was the most frequently mutated gene (23 %). Median progression-free survival (PFS) on first-line TKI treatment was 14.6 months (95% CI 9.9-18.4). BRAF mutation positively influenced median PFS, both in the entire TKI-treated cohort (median PFS 34.7 months versus 11.6 months; hazard ratio [HR] 0.29; 95% CI 0.09-0.98; p = 0.03) and in the TKI-treated PTC cohort (n = 22) [log-rank p = 0.086; HR 2.95; 95 % CI 0.81-10.70). However, in TKI-treated patients, PDTC histologic subtype was the only independent prognostic factor for PFS identified in the multivariate analysis (HR 2.36; 95% CI 1.01-5.54; p = 0.048).

We enrolled 190 patients (157 men and 33 women) with a mean (SD) age of 61.75 (10.85) years (range, 33-85 years). Of these patients, 144 received cytostatic treatment and 46 palliative treatment. The median survival was 31 weeks and was related to absence of weight loss (hazard ratio [HR], 1.73; 95% confidence interval [CI], 1.26-2.39; P=.001), cytostatic treatment (HR, 1.85; 95% CI, 1.25-2.76; P=.002), and ECOG score of 0 to 1 (HR, 2.84; 95% CI, 1.62-5.00; P=.0001). In patients with ECOG scores of 0 to 1, weight loss and treatment were significant prognostic factors. Survival in the ECOG 2 group was 15 weeks for patients undergoing cytostatic treatment and 11 weeks for patients with symptomatic treatment.

Does the type of tibial component affect mechanical alignment in unicompartmental knee replacement?

There are a number of factors responsible for the longevity of unicompartmental knee replacements (UKR). These include the magnitude of postoperative alignment and the type of material used. The effect of component design and material on postoperative alignment, however, has not been explored.

Does either obesity or OSA severity influence the response of autotitrating CPAP machines in very obese subjects?

The pressures delivered by autotitrating continuous positive airways pressure (CPAP) devices not only treat obstructive sleep apnoea (OSA) effectively but also give potentially interesting physiological information about the forces impinging on the pharynx. In earlier work from this unit, we used correlations between autoCPAP pressure and both OSA severity and obesity, to construct an algorithm to estimate the fixed CPAP pressure a patient required for subsequent clinical use. We wished to discover if these relationships could be reliably extended to a much more obese group.

Aripiprazole: a new risk factor for pathological gambling?

The patients involved were schizophrenic or bipolar, mostly young men with a history of addictive disorders and regular gambling prior to the prescription of aripiprazole. For each one of them, the causality of aripiprazole was considered, using an algorithm. The probability that pathological gambling is actually due to aripiprazole is "possible" in 7 cases out of 8, and "doubtful" in one.

Aripiprazole: a new risk factor for pathological gambling?

Power of RCTs to unveil a significant association between RBC storage duration and clinical outcomes was critically dependent on a complex interaction among three factors: 1) the way the RBC storage time is categorized in the trial design, 2) the temporal pattern assumed for the RBC storage lesion, and 3) the age distribution of RBCs in the inventory from which they are picked up for transfusion. For most combinations of these factors, the power of RCTs to detect a significant treatment effect was below 80%. All the four simulated RCTs had a very low power to disclose a harmful clinical effect confined to last week of the maximum 42-day shelf life of stored RBCs.

Immune suppression by lysosomotropic amines and cyclosporine on T-cell responses to minor and major histocompatibility antigens: does synergy exist?

Using murine models, we have shown that the lysosomotropic amine, chloroquine, is effective in the prevention of graft-versus-host disease (GVHD) mediated by donor T cells reactive with recipient minor histocompatibility antigens (MiHCs). Because lysosomotropic amines can suppress major histocompatibility complex (MHC) class II antigen presentation, their mechanism of action is potentially different from current immune suppressant drugs used to control GVHD such as cyclosporine.

Participants of this study were highly competent athletes, each training in different sport disciplines. The experimental group consisted of 18 athletes (4 women, 14 men), whereas the Control group had 21 athletes (4 women, 17 men). All athletes were between 16 and 34 years old. The biofeedback device, Nexus 10, was used to detect and measure the psychophysiological responses of athletes. Athletes from both groups (control and experimental) were subjected to stress tests at the beginning of the study and once again at its conclusion. In between, the experimental group received training in biofeedback techniques. We then calculated the overall percentage of athletes in the experimental group compared with those in the control group who were able to control respiration, skin conductance, heart rate, blood flow amplitude, heart rate variability, and heart respiration coherence. One year following completion of the initial study, we questioned athletes from the experimental group, to determine whether they continued to use these skills and if they could detect any subsequent enhancement in their athletic performance.

Detailed analysis of sputum and systemic inflammation in asthma phenotypes: are paucigranulocytic asthmatics really non-inflammatory?

The total non-squamous cell count per gram of sputum was greater in mixed granulocytic and neutrophilic phenotypes as compared to eosinophilic, paucigranulocytic asthma and healthy subjects (p < 0.005). Sputum eosinophils (in absolute values and percentages) were increased in all asthma phenotypes including paucigranulocytic asthma, compared to healthy subjects (p < 0.005). Eosinophilic asthma showed higher absolute sputum neutrophil and lymphocyte counts than healthy subjects (p < 0.005), while neutrophilic asthmatics had a particularly low number of sputum macrophages and epithelial cells. All asthma phenotypes showed an increased blood leukocyte count compared to healthy subjects (p < 0.005), with paucigranulocytic asthmatics having also increased absolute blood eosinophils compared to healthy subjects (p < 0.005). Neutrophilic asthma had raised CRP and fibrinogen while eosinophilic asthma only showed raised fibrinogen compared to healthy subjects (p < 0.005).

In-depth interviews were conducted with 10 graduates (per program), working in low- and middle-income health systems, their peers, and their supervisors.

Is HIV/STD control in Jamaica making a difference?

AIDS case reports, HIV testing of blood donors, antenatal clinic attenders (ANC), food service workers, sexually transmitted disease (STD) clinic attenders, female prostitutes, homosexuals and other groups were used to monitor the HIV/AIDS epidemic. Primary and secondary syphilis and cases of congenital syphilis were also monitored. National knowledge, attitude and practice (KAP) surveys were conducted in 1988, 1989, 1992, 1994 and 1996.

Is HIV/STD control in Jamaica making a difference?

Studies on coronary risk factors in men and women are mainly based on mortality data and few compare results of both sexes with consistent study design and diagnostic criteria. This study assesses the major risk factors for coronary events in men and women from the Reykjavik Study.

Is Panton-Valentine leucocidin associated with the pathogenesis of Staphylococcus aureus bacteraemia in the UK?

Four out of 244 isolates (1.6%) were PVL-positive and susceptible to oxacillin [methicillin-susceptible S. aureus (MSSA)]. Eighty-eight out of 244 (36%) were oxacillin-resistant (methicillin-resistant S. aureus), but none was PVL-positive. The four patients (two males: 30 and 33 years; two females: 62 and 80 years) had infection foci of: skin and soft tissue, unknown, indwelling line, and surgical site, and were located at one centre in Wales, one in England and two in Ireland. One of four PVL-positive isolates was resistant to penicillin and fusidic acid, the remainder were susceptible to all antibiotics tested. Genotypic analyses showed that the four isolates represented three distinct strains; the two isolates from Ireland were related.

Is Panton-Valentine leucocidin associated with the pathogenesis of Staphylococcus aureus bacteraemia in the UK?

All referrals to the breast MDT where breast cancer was diagnosed from 1 July 2009 to 30 June 2011 were included. Multidisciplinary team decisions were compared with subsequent patient management and classified as concordant or discordant.

Are even impaired fasting blood glucose levels preoperatively associated with increased mortality after CABG surgery?

During 2001-03, 1895 patients underwent primary CABG [clinical DM (CDM) in 440/1895; complete data on fB-glu for n=1375/1455]. Using pre-operative fB-glu, non-diabetics were categorized as having normal fB-glu (<5.6 mmol/L), IFG (5.6<or =fB-glu<6.1 mmol/L), or suspected DM (SDM) (>or =6.1 mmol/L). fB-glu was normal in 59%. The relative risks of 30 day and 1 year mortality compared with patients with normal fB-glu was 1.7 [95% confidence interval (CI): 0.5-5.5] and 2.9 (CI: 0.8-11.2) with IFG, 2.8 (CI: 1.1-7.2) and 1.9 (CI: 0.5-6.3) with SDM vs. 1.8 (CI: 0.8-4.0) and 1.6 (CI: 0.6-4.3) if CDM, respectively. The receiver operator characteristic area for the continuous variable fB-glu and 1 year mortality was 0.65 (P=0.002).

Are even impaired fasting blood glucose levels preoperatively associated with increased mortality after CABG surgery?

Among 109,173 live singleton deliveries, 530 women had visited ED due to asthma during pregnancy. While having an ED visit for asthma was positively associated with teenage pregnancy, low income, and presence of pregnancy-induced hypertension, it was not associated with fetal gender (OR 1.01, 95% CI 0.85-1.19). Fetal gender was not a significant predictor of adverse pregnancy outcomes among women who had an asthma ED visit during pregnancy.

Does positron emission tomography change management in primary rectal cancer?

Forty-six patients with advanced primary rectal cancer referred for consideration of adjuvant preoperative therapy underwent position emission tomography scanning. The referring physicians prospectively recorded each patient's stage following conventional imaging and the proposed treatment plan prior to position emission tomography scanning. This was then compared with subsequent stage and actual management implemented, and the appropriateness of position emission tomography-induced changes was noted by subsequent clinical follow-up.

Does positron emission tomography change management in primary rectal cancer?

The overall clinical follow-up rate was 88%, and the mean clinical follow-up duration was 16.4 months. The mean radiographic follow-up rate was 83%, and the mean length of radiographic follow-up was 9.3 months. There were no significant differences in the estimated blood loss (EBL) or length of hospital stay (LOS) between the groups (p>0.05). The mean EBL and LOS for the degenerative group were 206 ml and 3.7 days, respectively. The mean EBL and LOS for the OPLL group were 155 ml and 4 days, respectively. There was a statistically significant improvement of more than one grade in the Nurick score for both groups following surgery (p<0.05). The Nurick score improvement was not statistically different between the groups (p>0.05). The visual analog scale (VAS) neck pain scores were similar between groups pre- and postoperatively (p>0.05). The complication rates were not statistically different between groups either (p>0.05). Radiographically, both groups lost extension range of motion (ROM) following laminoplasty, but this change was not statistically significant (p>0.05).

Can you deliver accurate tidal volume by manual resuscitator?

One of the problems with manual resuscitators is the difficulty in achieving accurate volume delivery. The volume delivered to the patient varies by the physical characteristics of the person and method. This study was designed to compare tidal volumes delivered by the squeezing method, physical characteristics and education and practice levels.

Can you deliver accurate tidal volume by manual resuscitator?

We tested the ability of Disposable Antibacterial Coating (DAC) hydrogel (Novagenit Srl, Mezzolombardo, Italy) to deliver antibacterial agents using spectrophotometry and a microbiologic assay. Antibacterial and antibiofilm activity were determined by broth microdilution and a crystal violet assay, respectively. Coating resistance to press-fit insertion was tested in rabbit tibias and human femurs.

Can increases in the cigarette tax rate be linked to cigarette retail prices?

A retrospective cohort study of patients aged 2 to 18 years admitted to the King Abdul Aziz Medical City between May 2001 and May 2009 was conducted. Patients were categorized as lean (body mass index<95th percentile) and obese (body mass index ≥ 95th percentile). Groups were compared regarding admission demographics, mechanism of injury, pattern of injury, length of stay, intensive care unit admission, ventilation duration, types of procedures performed, injury severity score, and mortality.

Vertical lines in distal esophageal mucosa (VLEM): a true endoscopic manifestation of esophagitis in children?

The esophageal mucosa had a normal appearance on 160 endoscopic studies (Group 1) and VLEM were the only mucosal abnormalities in 41 endoscopies (Group 2). Histology was normal in 92 of 160 biopsies (57.5%) from Group 1, and 1 of 41 biopsies (2.4%) from Group 2. Most patients in Group 2 had eosinophilic esophagitis (34 of 41, 83%, specificity 0.85, sensitivity 0.5, p>0.001) which was of moderate to severe intensity (31 of 34, 91.2%, specificity 0.88, sensitivity 0.73, p<0.001).

Vertical lines in distal esophageal mucosa (VLEM): a true endoscopic manifestation of esophagitis in children?

Infants referred to our institution with a final diagnosis of ARM were retrospectively reviewed between 2001 and 2009. The first cohort consisted of patients that were referred between November 2001 and November 2006 with the diagnosis of an ARM that had been delayed for more than 48 h. The second cohort was those referred between December 2006 and May 2009 with whom the diagnosis of ARM had not been made within 24 h of birth.

Does hypoglycaemia increase the risk of cardiovascular events?

Hypoglycaemia caused by glucose-lowering therapy has been linked to cardiovascular (CV) events. The ORIGIN trial provides an opportunity to further assess this relationship.

Does hypoglycaemia increase the risk of cardiovascular events?

In a retrospective study between 1997 and 2005, we investigated 531 patients operated for aneurysm or ectasia of the ascending aorta (diameter: 45-76mm). Of these, in 50 patients, size-reducing ascending aortoplasty was performed. External reinforcement with a non-coated dacron prosthesis was added in order to stabilize the aortic wall.

Does the radiographic transition zone correlate with the level of aganglionosis on the specimen in Hirschsprung's disease?

Radiological findings were concordant with the specimen in pathology in 8 cases of 19 in rectal form (42 %), in 20 cases of 35 in rectosigmoid form (57 %), in all 6 cases of long-segment form (100 %), in the 2 cases of total colonic form (100 %) with a global agreement of 58.1 %, κ = 0.39 CI [0.24; 0.57].

Does the radiographic transition zone correlate with the level of aganglionosis on the specimen in Hirschsprung's disease?

Excellent association between acceleration response to VAS and pH>or = 7.20, and between a negative response to VAS (no acceleration or decelerations) and pH<7.20 were found in the first stage of labor, the second stage of labor, and the combination of both stages together (p = 0.0001, OR = 10.6 [3.3-34.0]). It was observed that negative VAS responses for predicting fetal acidosis (pH<7.20) were comparable between term (>or = 37 weeks) and preterm (<37 weeks,>or = 34 weeks) fetuses. Since the preterm fetuses enrolled in the study were limited in number, it is difficult to draw adequate conclusions. The positive predictive value (PPV) of fetal acidosis was 67% in both groups of FHR variable decelerations and late decelerations, but the false negative rate of acceleration VAS response for predicting no acidosis was significantly higher in the group of late decelerations (29% vs 8%, p = 0.034). Finally, both a negative VAS response and fetal acidosis (pH<7.20) have equal predictability for neonatal morbidity. The PPV of NICU admission by a negative VAS response was two times higher than that of fetal acidosis (PPV = 61% vs 29%, p = 0.038).

Is dexamethasone an effective alternative to oral prednisone in the treatment of pediatric asthma exacerbations?

Six completed pediatric clinical trials met the inclusion criteria. All of the pediatric trials found that prednisone is not superior to dexamethasone in treating mild to moderate asthma exacerbations. Meta-analysis demonstrated homogeneity between the dexamethasone and prednisone groups when examining symptomatic return to baseline and unplanned physician revisits after the initial emergency department encounter. Some studies found potential additional benefits of dexamethasone, including improved compliance and less vomiting.

Is dexamethasone an effective alternative to oral prednisone in the treatment of pediatric asthma exacerbations?

Ageing is a growing issue for people from UK black, Asian and minority ethnic (BAME) groups. The health experiences of these groups are recognised as a 'tracer' to measure success in end of life patient-preferred outcomes that includes place of death (PoD).AIM: To examine patterns in PoD among BAME groups who died of cancer.

A retrospective registry-based study.

Mammographic screening in Sami speaking municipalities and a control group. Are early outcome measures influenced by ethnicity?

Seventeen thousand five hundred and thirty-one measurements of either serum amylase and or serum pancreatic lipase were made on 10 931 patients treated at a metropolitan teaching hospital between January 2001 and May 2003. Of these, 8937 were initially treated in the Emergency Department. These results were collected in a database, which was linked by the patients' medical record number to the radiology and medical records. Patients with either an elevated lipase value or a discharge diagnosis of acute pancreatitis had their radiological diagnosis reviewed along with their biochemistry and histology record. The diagnosis of acute pancreatitis was made if there was radiological evidence of peripancreatic inflammation.

Do Electrochemiluminescence Assays Improve Prediction of Time to Type 1 Diabetes in Autoantibody-Positive TrialNet Subjects?

Univariate analyses showed that autoantibodies by radioimmunoassays (RIAs), ECL-IAA, ECL-GADA, age, sex, number of positive autoantibodies, presence of HLA DR3/4-DQ8 genotype, HbA1c, and oral glucose tolerance test (OGTT) measurements were all significantly associated with progression to diabetes. Subjects who were ECL positive had a risk of progression to diabetes within 6 years of 58% compared with 5% for the ECL-negative subjects (P<0.0001). Multivariate Cox proportional hazards models were compared, with the base model including age, sex, OGTT measurements, and number of positive autoantibodies by RIAs. The model with positivity for ECL-GADA and/or ECL-IAA was the best, and factors that remained significantly associated with time to diabetes were area under the curve (AUC) C-peptide, fasting C-peptide, AUC glucose, number of positive autoantibodies by RIAs, and ECL positivity. Adding ECL to the Diabetes Prevention Trial risk score (DPTRS) improved the receiver operating characteristic curves with AUC of 0.83 (P<0.0001).

Do Electrochemiluminescence Assays Improve Prediction of Time to Type 1 Diabetes in Autoantibody-Positive TrialNet Subjects?

We received 210 completed surveys from 260 eligible residents (80.8%) and 21 of 24 program directors (87.5%) (overall 81.3%). Mandatory active outcome feedback was not present in any EM training program for admitted or discharged patients (0/21). Follow-up was performed electively by 89.4% of residents for patients admitted to the hospital, and by 44.2% of residents for patients discharged home. A majority of residents (76.9%) believed that patient follow-up should be mandatory compared to 42.9% of program directors (p=0.002). The perceived educational value of outcome feedback was 5.8/7 for residents and 5.1/7 for program directors (difference 0.7; p=0.002) based on a seven-point Likert scale (1=not important; 7=very important).
