Conquering the inner couch potato: precommitment is an effective strategy to enhance motivation for effortful actions

Letting effort-free gratification derail us from effort-requiring goals is one reason why we fail to realize health-relevant intentions like ‘exercise regularly’. We tested the effectiveness of the self-control strategy precommitment in such effort-related conflicts, using a novel laboratory choice paradigm, where participants could precommit to an effort-requiring large reward by pre-eliminating an effort-free small reward from their choice set. Our participants used precommitment frequently and effectively, such that they reached effort-requiring large rewards more often. Using computational modelling and Bayesian model comparisons, we assessed whether participants employed precommitment to avoid anticipated willpower failures (i.e. as a self-regulatory measure) or to maximize their motivation to choose the effort-requiring option (i.e. as a self-motivational measure). Observed choices and precommitment decisions were consistent with the motivation maximization hypothesis, but not the willpower hypothesis. Our findings show that offering precommitment is effective in helping individuals optimize their motivation and choice behaviour and thereby achieve effort-requiring goals, and strongly encourage application of precommitment schemes in exercise and rehabilitation interventions.

A sample of non-nutritive sucking habits (pacifier and digit) in portuguese children and its relation with the molar classes of angle

Background Little is known about the effect of non-nutritive sucking habits (pacifier and digital sucking) in the prevalence of molar Class in mixed dentition. The aim of this study was determinate the relation between non-nutritive sucking habits, and Angle´s molar Class, in the horizontal plane, and it´s relation with gender. A convenience sample of 326 children with ages between 6 and 12 years was selected from three schools of Oporto. Material and Methods To collect the epidemiologic data, was used a method recommended by the WHO. An indirect questionnaire about the medical history, dental habits, was used. It was adapted from Sanchez-Molins and validated by Clinical Dental III of Integrated Dental University Institute Health Sciences, Gandra, Portugal. Results In this study, 326 infants were examined in order to determine the prevalence of non-nutritive sucking habits. Only 45 observed children did not mentioned any kind of non-nutritive sucking habit; the remaining 281 children mentioned at least one potential bad habit. Children with non-nutritive sucking habits show a higher molar Class II percentage in females, while molar Class III is more frequent among males compared with children with no sucking habits. Conclusions Children with non-nutritive sucking habits, presented a higher-Class II prevalence with statistically significance. It was detected a direct relationship between Angle´s molar Class and gender. Key words:Finger sucking, pacifier sucking, Angle Class malocclusion.
Evaluation of real-world persistence of propiverine and trospium chloride in treatment of overactive bladder in Germany

Treatment persistence poses a crucial criterion for therapeutic success. Like in many other chronic diseases, in overactive bladder (OAB) syndrome also, many patients discontinue their treatment for diverse reasons. In order to evaluate the persistence in medication, this paper presents data of propiverine extended release (ER) and trospium chloride immediate release (IR) for three consecutive quarters, thus giving an insight into the probability of treatment discontinuation for these two drugs. Prescription data from German health insurances were analyzed. The frequency of follow-up prescriptions and drop-outs for propiverine ER and trospium chloride IR were compared for treatment-naïve, restarted, and switched patients after treatment initiation (quarter 1) for a period of 9 months (three consecutive calendar quarters). In all analyzed quarters, the percentage of follow-up prescriptions was significantly higher for propiverine ER than for trospium chloride IR. The chance of a follow-up prescription was also significantly higher for propiverine ER than for trospium chloride IR, although, in general, both drugs showed a decrease of follow-up prescriptions over time. This comparison of propiverine ER (once-daily administration) and trospium chloride IR (in a multiple dose administration) in patients with OAB syndrome demonstrates that there are substantial differences in the odds of a follow-up prescription. The longer a patient adheres to a therapeutic treatment plan, the better the chances for improvement of symptoms and having a positive impact on activities of daily living.
Immunotherapy for HER2-positive breast cancer: recent advances and combination therapeutic approaches

Cancer immunotherapy has evolved dramatically with improved understanding of immune microenvironment and immunosurveillance. The immunogenicity of breast cancer is rather heterogeneous. Specific subtypes of breast cancer such as estrogen receptor (ER)-negative, human EGF receptor 2 (HER2)-positive, and triple-negative breast cancer (TNBC) have shown evidence of immunogenicity based on tumor–immune interactions. Several preclinical and clinical studies have explored the potential for immunotherapy to improve the clinical outcomes for different subtypes of breast cancer. This review describes the immune microenvironment of HER2-positive breast cancer and summarizes recent clinical advances of immunotherapeutic treatments in this breast cancer subtype. The review provides rationale and ongoing clinical evidence to the use of immune checkpoint inhibitors, therapeutic vaccines, and adoptive T cell immunotherapy in breast cancer. In addition, the present paper describes the most relevant clinical progress of strategies for the combination of immunotherapy with standard treatment modalities in HER2-positive breast cancer including chemotherapy, targeted therapy, and radiotherapy.
Evaluation of endocan and endoglin levels in chronic kidney disease due to diabetes mellitus

Introduction Endocan and endoglin have been shown to play a role in angiogenesis. Aberrant excessive angiogenesis is a main factor in the development of diabetic nephropathy. In this study we evaluated endocan and endoglin levels in diabetes patients with and without albuminuria and compared them with healthy subjects. Therefore we aimed at gaining a better understanding of the role of angiogenesis in diabetic nephropathy and to assess the predictive role of endocan and endoglin as markers of diabetic nephropathy progression. Material and methods Ninety-six type 2 diabetes patients were classified according to their 24-hour urinary albumin excretion rate. Forty type 2 diabetes patients with normoalbuminuria (urinary albumin excretion < 30 mg/day), 56 type 2 diabetes patients with diabetic nephropathy (with a urinary albumin excretion ≥ 30 mg/day) and 35 healthy non-diabetic control subjects were included. Their anthropometric features, arterial blood pressures, fasting glucose, glycated hemoglobin, urea, creatinine, lipids, endocan and endoglin levels were measured and compared to each other. Results Endocan and endoglin levels of diabetics patients were higher than those of the controls. In comparison of endocan and endoglin levels of diabetic nephropathy patients with controls, p-values were < 0.001 and 0.002 respectively. In comparison of normoalbuminuric diabetic patients with controls, p-values were 0.001 and 0.017 respectively. Endocan levels of diabetic nephropathy cases were higher than those of normoalbuminuric patients (p = 0.011) but there was no statistically significant difference in endoglin levels between them (p = 0.822). Conclusions Endocan might be a more reliable marker of diabetic nephropathy development than endoglin.
Ontogeny of vocal rhythms in harbor seal pups: an exploratory study

Abstract Puppyhood is a very active social and vocal period in a harbor seal’s life Phoca vitulina. An important feature of vocalizations is their temporal and rhythmic structure, and understanding vocal timing and rhythms in harbor seals is critical to a cross-species hypothesis in evolutionary neuroscience that links vocal learning, rhythm perception, and synchronization. This study utilized analytical techniques that may best capture rhythmic structure in pup vocalizations with the goal of examining whether (1) harbor seal pups show rhythmic structure in their calls and (2) rhythms evolve over time. Calls of 3 wild-born seal pups were recorded daily over the course of 1–3 weeks; 3 temporal features were analyzed using 3 complementary techniques. We identified temporal and rhythmic structure in pup calls across different time windows. The calls of harbor seal pups exhibit some degree of temporal and rhythmic organization, which evolves over puppyhood and resembles that of other species’ interactive communication. We suggest next steps for investigating call structure in harbor seal pups and propose comparative hypotheses to test in other pinniped species.
Cost-effectiveness of physical activity in the management of COPD patients in the UK

Background While the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines advise exercise to reduce disease progression, little investment in promoting physical activity (PA) is made by health care authorities. The purpose of this study was to estimate the cost-effectiveness of regular PA vs sedentary lifestyle in people with COPD in the UK. Methods Efficacy, quality of life, and economic evidence on the PA effects in COPD patients were retrieved from literature to serve as input for a Markov microsimulation model comparing a COPD population performing PA vs a COPD population with sedentary lifestyle. The GOLD classification defined the model health states. For the base case, the cost of PA was estimated at zero, a lifetime horizon was used, and costs and effects were discounted at 3.5%. Analyses were performed from the UK National Health Service (NHS) perspective. Uncertainty around inputs and assumptions were explored via scenario and sensitivity analyses, including a cost threshold analysis. Outcomes were cost/quality-adjusted life year (QALY) gained and cost/year gained. Results Based on our model, the effects of PA in the UK COPD population would be lower mortality (−6%), fewer hospitalizations (−2%), gains in years (+0.82) and QALYs (+0.66), and total cost savings of £2,568. The cost/QALY and cost/year gained were dominant. PA was cost-saving at costs <£35/month and cost-effective at cost <£202/month. The main model drivers were age and PA impact on death and hospital-treated exacerbations. Conclusion Including PA in the management of COPD leads to long-term clinical benefits. If the NHS promotes only exercise via medical advice, this would lead to health care cost savings. If the NHS chose to fund PA, it would still likely be cost-effective.
Determinants of energy drinks consumption among the students of a Saudi University

BACKGROUND: Energy drinks contain stimulants mainly caffeine. The use of these drinks by university students is on the rise despite concerns about their safety. This study identified the determinants of the consumption of energy drinks in a cohort of Saudi university students. MATERIALS AND METHODS: This cross-sectional study was carried out at Imam Abdulrahman Bin Faisal University in Saudi Arabia. The students who volunteered to participate (n = 1255) were asked to complete a pretested questionnaire soliciting information on gender, marital status, class and college of study, pattern of energy drinks use, reasons for use, any benefits as well as any untoward effects experienced. Data was analysed using IBM-SPSS (version 21) to determine frequencies and compare various categories of the energy drink users. Logistic regression analysis were performed to identify determinants of energy drinks consumption. RESULTS: Out of 1255 participants, 245 reported using energy drinks. Out of a total 1255 students, 903 (72%) were from medical and 352 (28%) from nonmedical colleges of the university. There were 890 junior and 365 senior students. The female participants were significantly more among both senior and junior medical students. The age of the participants (mean ± SD) was 20.2 ± 1.9 years. The frequency of energy drinks users was higher in the male nonmedical students (both senior and junior) compared to the medical students. The most significant determinants identified were male gender (odds ratio [OR] 4.2, 95% confidence interval [CI] =3.34, 6.12), and being single (OR = 2.8, CI = 1.98, 4.24). In addition, being in non-medical field of study (OR = 1.3, 95% CI=0.61-2.13) was also found to have a reasonable association with energy drink consumption. CONCLUSION: We report male gender, unmarried status, and studying in nonmedical colleges of the university as the main determinants of the consumption of energy drinks by university students. Scrutiny of the patterns and reasons for the consumption of energy drinks might help in developing educational interventions to ensure the appropriate use of energy drinks by young adults.
Gonatopusjaliscanus sp. n., a new Pincer wasp from Jalisco, Mexico (Hymenoptera, Dryinidae)

Abstract A new species of Gonatopus Ljungh, 1810, G.jaliscanussp. n. , from Jalisco, Mexico, is described and illustrated. In the Neotropical region, G.jaliscanus is similar to G.forestalis Olmi, 1998, but it is distinguished by the black mesosoma (except prothorax, mesoscutum, and mesoscutellum that are yellow), and the metapostnotum being granulated and not rugose; in G.forestalis the mesosoma is completely black and the metapostnotum is granulated and strongly rugose. In the Nearctic region, the new species is morphologically similar to G.curriei Krombein, 1962, but it is distinguished by the dull and granulated metapostonotum; in G.curriei the metapostnotum is shiny and unsculptured. The new species belongs to Gonatopus group 7. The keys to the females of the Nearctic and Neotropical species of this group are modified to include the new taxon.
A retrospective study of conscious sedation versus general anaesthesia in patients scheduled for transfemoral aortic valve implantation: A single center experience

The current 2017 ESC/EACTS guidelines recommend transcatheter aortic valve implantations (TAVIs) as the therapy of choice for inoperable patients with severe symptomatic aortic stenosis. Most of the TAVIs worldwide are performed under general anaesthesia (GA). Although conscious sedation (CS) concepts are increasingly applied in Europe, it is still a matter of debate which concept is associated with highest amount of safety for this high‐risk patient population. The aim of this single center, before‐and‐after study was to investigate feasibility and safety of CS compared with GA with respect to peri‐procedural complications and 30‐day mortality in patients scheduled for transfemoral TAVI (TF‐TAVI).
Association between maxillary and mandibular apical base lengths and severity of dental crowding or spacing in Class II malocclusion subjects: An in-vitro study

Background Anterior crowding/ spacing are one of the major problems that inspire patients to undergo orthodontic treatment. Several factors associated with anterior crowding/ spacing includes arch width and length, mesio-distal tooth diameter and proportions. The aim of the present study was to evaluate the relationship of maxillary and mandibular base lengths to the amount of anterior dental crowding/ spacing in patients with complete class II malocclusions. Material and Methods A retrospective study was done with 152 patients who were divided into four groups according to the severity of pre-treatment dental crowding/spacing present in the mandibular arch. Measurements were performed on the pre-treatment dental casts and lateral cephalograms. Statistical analysis was done using t-test and chi-square test. Results Subjects with complete class II malocclusion and moderate to severe mandibular crowding [≥3mm] have significantly smaller base lengths as compared to the subjects with slight crowding or spacing [<3mm]. Conclusions There exists an inverse correlation between maxillary and mandibular base lengths and the severity of dental crowding and direct correlation with spacing. Key words:Apical base lengths, Class II malocclusion, Crowding, Incisor inclination, Spacing.
Validity of first-time diagnoses of congenital epidermolysis bullosa in the Danish National Patient Registry and the Danish Pathology Registry

Purpose Congenital epidermolysis bullosa (CEB) is a group of rare monogenic genodermatoses. Phenotypically, the diseases vary in both severity and dissemination, which complicates studies of their epidemiology. To investigate the potential of using the Danish National Patient Registry (DNPR) for epidemiological research on CEB, we examined the positive predictive value (PPV) of a first-time diagnosis of CEB. Methods We identified patients with a record of CEB in DNPR and the Danish Pathology Registry (DPR) during January 1, 1977, until December 31, 2015. We restricted diagnoses from two dermatological departments and one regional hospital. Diagnoses in the DNPR are coded by the eighth and tenth revisions of the ICD (ICD-8 and ICD-10) and in the DPR by the Systematized Nomenclature of Medicine (SNOMED). We used clinical description in medical records, family history, histological findings, and molecular genetic investigations to validate diagnoses and classified them as rejected and confirmed. We estimated PPVs for any diagnosis, according to coding systems used, and for additional subdivisions of ICD-10 codes. Results We identified 116 cases from the hospital departments investigated and evaluated 96 medical records for validity. The overall PPV for probable CEB was 62.5% (95% CI: 52.5–71.5). For ICD-8, ICD-10, and SNOMED codes, the PPVs were 30.8% (95% CI: 11.4–57.7), 76.7% (95% CI: 65.8–84.9), and 0.0% (95% CI: 0.0–21.7), respectively. For the ICD-10 codes, we found the highest PPVs for diagnoses arising from the dermatological departments. For subdivisions of ICD-10 codes, PPVs were high for epidermolysis bullosa simplex and dystrophica. Conclusion The PPVs for first-time diagnoses of CEB registered in the two Danish nationwide registries investigated, DNPR and DPR, ranged from low to average. We therefore recommend that these data be used with caution and restricted to ICD-10 diagnoses from specialized dermatological departments.
Clinical, Virologic, and Immunologic Characteristics of Zika Virus Infection in a Cohort of US Patients: Prolonged RNA Detection in Whole Blood

Abstract Background Clinical, virologic, and immunologic characteristics of Zika virus (ZIKV) infections in US patients are poorly defined. Methods US subjects with suspected ZIKV infection were enrolled. Clinical data and specimens were prospectively collected for ZIKV RNA detection and serologic and cellular assays. Confirmed ZIKV infection (cases) and ZIKV-negative (controls) subjects were compared. Dengue-experienced and dengue-naïve cases were also compared. Results We enrolled 45 cases and 14 controls. Commonly reported symptoms among cases and controls were maculopapular rash (97.8% and 81.8%), fatigue (86.7% and 81.8%), and arthralgia (82.2% and 54.5%), respectively. The sensitivity (94%) and duration of infection detection (80% positivity at 65–79 days after disease onset) by polymerase chain reaction were highest in whole-blood specimens. ZIKV-neutralizing antibodies had a half-life of 105 days and were significantly higher in dengue virus–experienced cases than naïve ones (P = .046). In intracellular cytokine staining assays, the ZIKV proteins targeted most often by peripheral blood mononuclear cells from cases were structural proteins C and E for CD4+ T cells and nonstructural proteins NS3, NS5, and NS4B for CD8+ T cells. Conclusions ZIKV RNA detection was more frequent and prolonged in whole-blood specimens. Immunoglobulin G (IgG) and neutralizing antibodies, but not IgM, were influenced by prior dengue infection. Robust cellular responses to E and nonstructural proteins have potential vaccine development implications.
QTLs for agronomic traits detected in recombinant inbred lines derived from a bread wheat × spelt cross

Spelt wheat (Triticum aestivum subsp. spelta), a subspecies of common wheat, is a genetic resource for the breeding of bread wheat (T. aestivum subsp. aestivum); however, genetic analyses of agronomic traits in bread wheat × spelt crosses are insufficient. Here, we conducted QTL analysis in the recombinant inbred lines from a bread wheat × spelt cross. In addition to the major Q locus, QSpd.obu-4D was detected with the spelt allele conferring a higher spikelet density than the bread wheat allele. The effect of QSpd.obu-4D was evident in the presence of the Q allele of bread wheat, suggesting that this variation might be cryptic in spelt wheat with the q allele. Two QTLs with stable effects were identified for grain length, one of which (QGl.obu-1A) has never been detected in a bread wheat × spelt cross. The spelt wheat allele at QHt.obu-7B conferring later heading was identified in the Vrn-B3 region and could be a novel gene source for modifying heading time. Furthermore, QGi.obu-2B, responsible for low grain dormancy of spelt wheat, was detected. Further exploration and identification of useful QTLs could accelerate the utilization of spelt wheat as a genetic resource for bread wheat breeding programs.
TMEFF1 overexpression and its mechanism for tumor promotion in ovarian cancer

Background Transmembrane protein with epidermal growth factor-like and two follistatin-like domains 1 (TMEFF1) has an anticarcinogenic effect in brain tumors. However, little is known about the role of TMEFF1 in epithelial ovarian cancer (EOC). Materials and methods TMEFF1 expression in EOC was detected by immunohistochemistry; its relationship with clinical pathological parameters and its influence on prognosis were analyzed. The MTT, scratch, Transwell assays, and flow cytometry were used to assess the malignant behavior of ovarian cancer cell. Changes in node proteins in MAPK and PI3K/AKT signaling pathways and the expression of epithelial–mesenchymal transformation markers were measured by Western blot. The regulatory effect of p53 on TMEFF1 was verified by chromatin immunoprecipitation (ChIP) assay and Western blot. Results TMEFF1 expression was higher in the EOC group than in the borderline and benign tumor groups and normal ovary group; its high expression was significantly related to International Federation of Gynecology and Obstetrics stage (P=0.024) and independently predicted shorter overall survival (P<0.01). TMEFF1 overexpression in ovarian cancer cells induced increased cellular proliferation, migration, and invasion but reduced apoptosis. In addition, the percentage of phosphorylated node proteins in MAPK and PI3K/AKT signaling pathways increased significantly. The expression of E-cadherin decreased but that of vimentin and N-cadherin increased. After the addition of MAPK (PD98059) and PI3K (GDC-0941) pathway inhibitors, ovarian cancer cells overexpressing TMEFF1 showed suppressed malignant behavior. TMEFF1 protein expression in an ovarian cancer cell lines (CAOV3 and ES-2) was downregulated after the inhibition of TP53. The transcription factor, p53, bound the promoter region of the TMEFF1 gene according to ChIP. Conclusion TMEFF1 is a carcinogenic gene in ovarian cancer and can be regulated by p53 transcription. Through MAPK and PI3K/AKT signaling pathways, TMEFF1 promotes the malignant behavior in EOC. Therefore, TMEFF1 may be considered as a potential therapeutic target for ovarian cancer.
