Are Analysts’ Recommendations Informative? Intraday Evidence on the Impact of Time Stamp Delays
Authors: BRADLEY DANIEL , CLARKE JONATHAN , LEE SUZANNE , ORNTHANALAI CHAYAWAT 
Published: October 2013

ABSTRACTWe demonstrate that time stamps reported in I/B/E/S for analysts’ recommendations released during trading hours are systematically delayed. Using newswire‐reported time stamps, we find 30‐minute returns of 1.83% (−2.10%) for upgrades (downgrades), but for this subset of recommendations we find corresponding returns of −0.07% (−0.09%) using I/B/E/S‐reported time stamps. We also examine the information content of recommendations relative to management guidance and earnings announcements. Our evidence suggests that analysts’ recommendations are the most important information disclosure channel examined.

AbstractAimTo investigate the surgical outcomes, urinary incontinence and quality of life (QOL) of patients with pelvic organ prolapse after synthetic mesh‐augmented repair in the Chinese population.MethodThis is a retrospective study of women who underwent synthetic mesh‐augmented repair. Surgical outcomes were investigated by recurrence rate of prolapse and Organ Prolapse Quantification, and QOL by Pelvic Floor Impact Questionnaire‐7 (PFIQ‐7) and Pelvic Floor Distress Inventory‐20 (PFDI‐20). The sex life quality was evaluated by Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire‐31 (PISQ‐31).ResultsEighty‐three patients completed the entire study. Anatomical success was 90.36%. Of patients with preoperative stress urinary incontinence, 91.89% claimed that the incontinence symptoms were completely relieved. The 6‐month PFDI‐20 and PFIQ‐7 scores were significantly decreased, indicating that improved QOL occurs. However, the PISQ‐31 showed no significant difference between preoperative and postoperative data in sex life quality.ConclusionThe synthetic polypropylene mesh is effective in treating POP and may improve QOL with no significant difference in the sexual life postoperatively. De novo stress urinary incontinence may occur after synthetic mesh‐augmented repair.

AbstractRecently, transient inferior vena cava (IVC) filters have been employed to protect against pulmonary embolism (PE) in pregnant women with deep vein thrombosis. A 34‐year‐old primiparous Japanese woman with a history of myomectomy was diagnosed with deep vein thrombosis by ultrasound at 27 weeks of gestation. Unfractionated heparin was administered, which soon ameliorated swelling in the right thigh. A transient IVC filter was implanted just before cesarean section. An enhanced computed tomography scan 2 days after cesarean section revealed a wide thrombus just distal to the filter. We performed catheter thrombus fragmentation with fibrinolysis just before the removal of the IVC filter, resulting in re‐canalization of blood flow. No significant PE occurred. Although a transient IVC filter may work well for the prophylaxis of PE during labor and delivery, catheter fragmentation with fibrinolysis may become necessary at removal of the filter.

Published: October 2013

AbstractAimTo investigate the developmental competence of human embryos that originated from in vitro matured oocytes retrieved during cesarean section.MethodsImmature oocytes were collected from 95 pregnant women, who underwent cesarean section at Buddhachinaraj Hospital Medical School and consented to participate in the study. Retrieved oocytes were cultured in blastocyst medium supplemented with 75 IU/L of human menopausal gonadotropin. Oocyte maturation was assessed at 30 and 48 h after culture. In vitro matured oocytes were inseminated by intracytoplasmic sperm injection and cultured up to 144 h. The fertilization, cleavage and blastocyst formation rates were observed.ResultsMaturation rate of oocytes after 30 h of culture was 67.9% compared with 13.1% at 48 h (P < 0.0001). Insemination of oocytes in both groups resulted in similar fertilization, cleavage and blastocyst formation rates.ConclusionA large proportion of oocytes retrieved at the time of cesarean section exhibited the capacity to undergo maturation in vitro. They can be fertilized and developed into good‐quality blastocyst stage.

AbstractAimThe objective of this study was to review our experience with ectopic pregnancy management and to evaluate major predictive factors for failure of conservative linear salpingostomy.MethodsSeven hundred and ninety‐seven cases that were treated for ectopic pregnancy in our clinic between October 2005 and September 2011 were analyzed retrospectively for incidence and treatment options. We defined failure as rising or plateauing postoperative serum β‐hCG levels that required additional medical or surgical treatment after initial removal of the ectopic pregnancy by laparoscopy or by laparotomy. We examined the risk factors consisting of preoperative β‐hCG, size and location of ectopic lesions, the presence of fetal heart beat and tubal condition that can influence the failure or success of conservative salpingostomy.ResultsIn total, 403 patients were treated conservatively. These conservative managements consist of 334 salpingostomies performed by laparoscopy and 69 by laparotomy. Because of persistent ectopic pregnancy, 16 patients underwent medical treatment. In total, 387 patients were treated successfully with conservative management and 16 patients were treated unsuccessfully with conservative management. When variables of P < 0.05 were subjected to multivariate analysis, size of the ectopic pregnancy of 33.5 mm or greater and fimbrial and isthmic region ectopic pregnancies were significantly associated with the failure rate.ConclusionsThe size of the ectopic pregnancy and fimbrial and isthmic region ectopic pregnancies were determinant of failure of conservative surgery. Our success rate in the ruptured group is not an underestimated value to dissuade patients wishing to maintain fertility by undergoing salpingectomy. So, the conservative approach to ectopic pregnancy should be undertaken after careful patient evaluation.

AbstractAimThe aim of this study was to identify factors that can predict clinical course among patients hospitalized with pelvic inflammatory disease (PID).MethodsNinety‐three patients who needed hospitalization with a diagnosis of PID were retrospectively studied. Patients who were discharged within 7 days by conservative treatment were defined as favorable course cases (n = 44). Patients who needed more than 7 days of hospitalization and/or surgery were defined as poor course cases (n = 49). Twenty variables were evaluated by univariate and logistic regression analysis: age, history of pregnancy/delivery, gynecological open/laparoscopic surgery, PID, oral contraceptives/intrauterine device use and intrauterine operation before onset, body temperature, signs of peritoneal irritation, vomiting/diarrhea, abnormal vaginal discharge, endometriosis/fibroid/adenomyosis/any cystic lesion detected by ultrasonography, white blood cell counts/C‐reactive protein (CRP) levels . The cut‐off value was calculated by receiver–operator curve (ROC) analysis.ResultsFactors associated with poor clinical course were advanced age (P < 0.01), history of gynecological open surgery (P < 0.05), any cystic lesion detected by ultrasonography (P < 0.05) and high CRP levels (P < 0.05). High CRP levels and intrauterine operation before onset were independently associated with poor clinical course. The cut‐off value for CRP was 4.4 mg/dL.ConclusionThis study identified variables that can predict poor clinical course of PID. These results can assist gynecologists with identifying patients at risk and optimizing the choice of management.

ObjectivesTo investigate the outcomes of a cohort of acute and elective percutaneous coronary intervention (PCI) patients who were discharged home 6 hours postprocedure.BackgroundContemporary PCI is safe with a low rate of acute complications. It is well established as a day procedure in elective cases; however, data are lacking in acute cases.MethodsWe describe a prospective observational audit of routine clinical practice in the 3 PCI centers in Northern Ireland. Patients were selected for same‐day discharge after 6 hours of post‐PCI observation. Both elective and acute coronary syndrome (ACS) cases were included. Criteria for same‐day discharge were based on the technical result of the procedure rather than lesion complexity or clinical presentation. Radial access was preferred but not mandatory. Patients were contacted directly to assess for 30‐day major adverse cardiovascular events (MACE). Reported events were corroborated with the general practitioner or hospital notes.ResultsA total of 1,059 patients were selected for same‐day discharge with 30‐day follow‐up available for all cases. Of these, 766 (72.3%) were elective and 293 (27.7%) were ACS patients. Radial access was almost universal (98%). A total of 1,224 lesions were stented, of which 432 (40.8%) were high risk (highest risk lesion in each case by AHA/ACC classification). MACE rate at 30 days was 0.85% with a sub‐acute stent thrombosis rate of 0.4%. There were no MACE events from discharge to 24 hours.ConclusionsSelected acute and elective patients with a range of lesion complexity and risk can be discharged safely home early after PCI.

AbstractAimsThe four pivotal beta‐blocker trials in heart failure (HF) had different inclusion criteria, making comparison difficult without patient stratifying. The aim of this study was to compare, in similar patients, the effects of bisoprolol, metoprolol controlled release/extended release (CR/XL), carvedilol and nebivolol on (i) total mortality, (ii) all‐cause mortality or hospitalization due to cardiovascular causes (time to first event), (iii) all‐cause mortality or hospitalization because of HF and (iv) tolerability, defined as discontinuation of randomized treatment.MethodsWe compared stratified (s) subsets in MERIT‐HF with patients in CIBIS‐II [New York Heart Association (NYHA) class III/IV and ejection fraction (EF) ≤35%] and COPERNICUS (NYHA III/IV and EF <25%) and in patients with systolic HF in SENIORS‐SHF (age ≥70 years and EF ≤35%).ResultsThe annual mortality rates in the placebo and beta‐blocker arms were: (i) CIBIS‐II (n = 2647), 13.2% vs. 8.8% (relative risk reduction 34%, 95% CI: 19–46, P < 0.0001) and MERIT‐HFs (n = 2002), 14.8% vs. 8.6% (relative risk reduction 42%, 95% CI: 24–56, P < 0.0001); (ii) COPERNICUS (n = 2289), 19.7% vs. 12.8% (relative risk reduction 35%, 95% CI: 19–48, P = 0.0014) and MERIT‐HFs (n = 795), 19.1% vs. 11.7% (relative risk reduction 39%; 95% CI: 11–58, P = 0.0086); (iii) SENIORS‐SHF (n = 1359), 11.3% vs. 9.7% (relative risk reduction 16%, NS) and MERIT‐HFs (n = 985), 14.8% vs. 10.1% (relative risk reduction 32%, 95% CI: 2–53, P = 0.038). The effects on the other outcomes assessed were similar. Analyses indicated fewer discontinuations from randomized treatment on beta‐blockers compared with placebo in COPERNICUS and the MERIT‐HFs subsets.ConclusionThe efficacy and tolerability of bisoprolol, carvedilol and metoprolol CR/XL are similar in patients with systolic HF, irrespective of NYHA class or ejection fraction. Nebivolol is less effective and not better tolerated.
The effect of financial incentives on performance: A quantitative review of individual and team‐based financial incentives
Authors: Garbers Yvonne , Konradt Udo 
Published: October 2013

We meta‐analysed 146 studies (n = 31,861) to examine the effects of individual and team‐based financial incentives on peoples' performance and to explore potential moderators. The overall effect size of the individual incentives (116 studies) was positive (g = 0.32). Moderator analyses revealed effect sizes to be larger for field studies (g = 0.34) than for laboratory studies (g = 0.29), larger for qualitative (g = 0.39) than quantitative performance measures (g = 0.28), and smaller for less complex tasks (g = 0.19). Results on team‐based incentives (30 studies) indicated a positive effect regarding team‐based rewards on performance (g = 0.45), with equitably distributed rewards resulting in higher performance than equally distributed rewards. This relationship was larger in field studies and smaller for less complex tasks. In addition, our results show that the effect of team‐based rewards depends on team size and gender composition. Implications for organizational rewards and suggestions for future research are discussed.Practitioner points

Our study demonstrates the importance of rewarding employees as teams to motivate them to a greater extent.

The results show that equitably distributed rewards lead to higher performance than equally distributed rewards.

Managers should design their appraisal and feedback process for individual team members and the team as a whole.

Our results provide useful information regarding the creation of appropriate reward systems.

Differences in reward characteristics, team composition, and distribution rules offer practical implications for factors on organizational (i.e., personnel selection, frequency, and amount of rewards), team (i.e., team characteristics, type of performance measurement), and individual level (i.e., importance of rewards, personality).

SummaryLow taste sensitivity may be one factor related to undernutrition, which is a major problem in developing countries. The purpose of this cross‐sectional study was to examine the association between underweight, one indicator of undernutrition, and taste sensitivity in middle‐ to old‐aged Sri Lankan nursing home residents. Participants were 946 residents with BMI of <25·0 from 25 nursing homes. Data were obtained on height, weight, taste sensitivity, subjective taste ability, sex, age, ethnicity, number of years in nursing homes, activities of daily living (ADL), frequency of exercise, bowel movements, smoking status, drinking status, current number of chronic diseases, number and kinds of medications used, self‐reporting questionnaire 20 (SRQ20), subjective smell ability, number of teeth present, Eichner index and flow rate of saliva. Low sensitivity to bitter taste, being male, old age, low ADL, smoking experience, drinking experience, fewer medications used and no use of medication for hypertension and diabetes were each associated with underweight (P < 0·05). In a multilevel Poisson regression model adjusted for sex, age, ADL, smoking status, drinking status, number of medications used, use of medication for hypertension and diabetes and flow rate of saliva, subjects with low sensitivity (>0·003% quinine hydrochloride dihydrate) to bitter taste had a significant 1·70 times higher prevalence ratio (95% confident interval 1·04–2·80) for underweight compared with those with high sensitivity (0·0001% quinine hydrochloride dihydrate). These results suggest that low taste sensitivity to bitter taste may be one factor related to underweight.
Oral candidosis in relation to oral immunity
Authors: Feller L. , Khammissa R. A. G. , Chandran R. , Altini M. , Lemmer J. 
Published: October 2013

Symptomatic oral infection with Candida albicans is characterized by invasion of the oral epithelium by virulent hyphae that cause tissue damage releasing the inflammatory mediators that initiate and sustain local inflammation. Candida albicans triggers pattern‐recognition receptors of keratinocytes, macrophages, monocytes and dendritic cells, stimulating the production of IL‐1β, IL‐6 and IL‐23. These cytokines induce the differentiation of Th17 cells and the generation of IL‐17‐ and/or IL‐22‐mediated antifungal protective immuno‐inflammatory responses in infected mucosa. Some immune cells including NKT cells, γδ T cells and lymphoid cells that are innate to the oral mucosa have the capacity to produce large quantities of IL‐17 in response to C. albicans, sufficient to mediate effective protective immunity against C. albicans. On the other hand, molecular structures of commensal C. albicans blastoconidia, although detected by pattern‐recognition receptors, are avirulent, do not invade the oral epithelium, do not elicit inflammatory responses in a healthy host, but induce regulatory immune responses that maintain tissue tolerance to the commensal fungi. The type, specificity and sensitivity of the protective immune response towards C. albicans is determined by the outcome of the integrated interactions between the intracellular signalling pathways of specific combinations of activated pattern‐recognition receptors (TLR2, TLR4, Dectin‐1 and Dectin‐2). IL‐17‐mediated protective immune response is essential for oral mucosal immunity to C. albicans infection.
Transition from Failing Dentition to Full‐Arch Fixed Implant‐Supported Prosthesis with a Staged Approach Using Removable Partial Dentures: A Case Series

Published: October 2013

AbstractThe present retrospective case series is aimed at evaluating a staged approach using a removable partial denture (RPD) as an interim prosthesis in treatment to correct a failing dentition until such time as a full‐arch fixed implant‐supported prosthesis may be inserted. Eight patients, who had undergone maxillary full‐arch rehabilitation with dental implants due to poor prognosis of their dentitions, were analyzed. All treatment included initial periodontal therapy and a strategic order of extraction of hopeless teeth. An RPD supported by selected teeth rehabilitated the compromised arch during implant osseointegration. These remaining teeth were extracted prior to definitive prosthesis delivery. Advantages and drawbacks of this technique were also recorded for the cases presented. Among the advantages provided by the staged approach are simplicity of fabrication, low cost, and ease of insertion. Additionally, RPD tooth support prevented contact between the interim prosthesis and healing abutments, promoting implant osseointegration. The main drawbacks were interference with speech and limited esthetic results. Implant survival rate was 100% within a follow‐up of at least 1 year. The use of RPDs as interim prostheses allowed for the accomplishment of the analyzed rehabilitation treatments. It is a simple treatment alternative for patients with a low smile line.
Peer Status Among Incarcerated Female Offenders: Associations With Social Behavior and Adjustment

Published: October 2013

Peers are a powerful socializing force, especially during adolescence. Whether peer status holds the same meaning, correlates, and consequences for female offenders remains unknown. Using a peer nomination technique in a sample of incarcerated females (N = 86, age 15–24 years), our study is the first to examine the association between peer status and psychopathology in a correctional facility. Results indicated that a key indicator of likeability was prosocial behavior; popularity was related to leadership; and social impact was associated with aggression. Popularity might serve as a buffer against, and social impact as a risk factor for, psychosocial problems. Findings shed light on peer status as a mechanism underpinning female offenders' problem behaviors and an entry point for targeted interventions.

Published: October 2013

AimThe aim of this study is to compare the high‐frequency pressure amplitude (oscillatory change in pressure (ΔP)) and tidal volume (high‐frequency tidal volume at the airway opening (VTHF)) delivered by the Dräger VN500 (Drägerwerk Ag & Co., Lübeck, Germany) and the Sensormedics 3100 (SM3100; CareFusion, San Diego, CA, USA) through a range of oscillatory frequencies.MethodsIn this benchtop study, high‐frequency oscillations were applied to an infant test lung at unrestricted set amplitudes. Pressure and flow were measured as a function of frequency, incremented by 1 Hz from 5 to 15 Hz. Measurements were repeated for a range of ventilator settings, and lung resistive and compliance states.ResultsThe VN500, but not the SM3100, demonstrated an exponential decrease in airway opening ΔP as frequency increased. The difference between the SM3100‐ and VN500‐delivered VTHF became greater with each frequency increment. At 15 Hz, VN500 VTHF was 49% of SM3100 VTHF.ConclusionsThe VN500 demonstrates a frequency‐related reduction in ΔP not observed in the SM3100. Clinicians need to be aware of these differences in performance characteristics.
Coordinated Punishment and the Evolution of Cooperation
Authors: OLCINA GONZALO , CALABUIG VICENTE 
Published: October 2013

AbstractIn this paper, we analyze a team trust game with coordinated punishment of the allocator by investors and where there is also a final stage of peer punishment. We study the effect of punishment on the reward and the investment decisions, when the effectiveness and cost of coordinated punishment depend on the number of investors adhering to this activity. The interaction takes place in an overlapping‐generations model with heterogeneous preferences and incomplete information. The only long‐run outcomes of the dynamics are either a fully cooperative culture (FCC) with high levels of trust and cooperation and fair returns or a non‐cooperative culture with no cooperation at all. The basin of attraction of the FCC is larger; the higher the institutional capacity of coordinated punishment, the higher the level of peer pressure and the smaller the individual cost of coordinated punishment.
