Rolando De la Cruz, Claudio Fuentes, Cristian Meza, Dae-Jin Lee, Ana Arribas-Gil
We propose a semiparametric nonlinear mixed-effects model (SNMM) using penalized splines to classify longitudinal data and improve the prediction of a binary outcome. The work is motivated by a study in which different hormone levels were measured during the early stages of pregnancy, and the challenge is using this information to predict normal versus abnormal pregnancy outcomes. The aim of this paper is to compare models and estimation strategies on the basis of alternative formulations of SNMMs depending on the characteristics of the data set under consideration...

Motivated by the analysis of quality of life data from a clinical trial on early breast cancer, we propose in this paper a generalized partially linear mean-covariance regression model for longitudinal proportional data, which are bounded in a closed interval. Cholesky decomposition of the covariance matrix for within-subject responses and generalized estimation equations are used to estimate unknown parameters and the nonlinear function in the model. Simulation studies are performed to evaluate the performance of the proposed estimation procedures...

With the increasing availability of large prospective disease registries, scientists studying the course of chronic conditions often have access to multiple data sources, with each source generated based on its own entry conditions. The different entry conditions of the various registries may be explicitly based on the response process of interest, in which case the statistical analysis must recognize the unique truncation schemes. Moreover, intermittent assessment of individuals in the registries can lead to interval-censored times of interest...

Food intake is reduced by estrogenic hormones, levels of which vary throughout life and fluctuate throughout the ovarian cycle in females. However, estrogens have also been shown to increase reward derived from drugs of abuse, where motivational properties of drugs and progression to addiction are potentiated by estrogens. Whether reward derived from food, and specifically motivational properties of food, are altered by estrogens remains unknown. Here we investigated the effect of the estrous cycle on food reward behavior and show estrous cycle dictated variability in food motivation, measured by progressive ratio operant conditioning, in female rats...

Epilepsy is a brain and neurological disorder with high prevalence. It was reported that more than 70% of epileptic seizures were controlled by anti-epileptic medications, whereas the lack of evidence with respect to head-to-head comparisons motivated researchers to seek alternative approaches that are able to provide deep insights into the profile of anti-epileptic medications. In this study, we performed a network meta-analysis (NMA) to evaluate the efficacy and safety of anti-epileptic medications for partial seizures of epilepsy...

The capacity and motivation to be social is a key component of the human adaptive behavioral repertoire. Recent research has identified social behaviors remarkably similar to our own in other animals, including empathy, consolation, cooperation, and strategic deception. Moreover, neurobiological studies in humans, nonhuman primates, and rodents have identified shared brain structures (the so-called 'social brain') apparently specialized to mediate such functions. Neuromodulators may regulate social interactions by 'tuning' the social brain, with important implications for treating social impairments...

OBJECTIVES: Researchers have argued that leadership is one of the most important determinants of team effectiveness. The present study examined the extent to which the perceived quality of athlete leadership was related to the effectiveness of elite sports teams. DESIGN: Three professional football teams (N=135) participated in our study during the preparation phase for the Australian 2016 season. METHODS: Players and coaching staff were asked to assess players' leadership quality in four leadership roles (as task, motivational, social, and external leader) via an online survey...

The emphasis on esthetic outcomes and quality of life after breast cancer surgery has motivated surgeons to develop oncoplastic breast conserving surgery (OPS). Training programs are still rare in most countries, and there is little standardization, which challenges the scientific evaluation of the techniques. The present article attempts to standardize OPS nomenclature, indications, and reconstruction choice selection embedded in a thorough review of the literature. We propose four breast conserving surgery (BCS) categories: Conventional tumorectomy, oncoplastic mastopexy, oncoplastic tumorectomy and oncoplastic reduction mammoplasty...

The ecosystem services framework (ESF) is advantageous and widely used for itemising and quantifying ways in which humans benefit from natural places. However, it suffers from two important problems: (i) incoherence of definitions and (ii) a narrow approach to valuation, inadequate to represent the full range of human motives for conservation and the diverse interests of different stakeholders. These shortcomings can lead to a range of problems including double-counting, blind spots and unintended consequences...

REVIEW
Angela M Arlen
PURPOSE OF REVIEW: Dysfunctional voiding is defined as "habitual contraction of the urethral sphincter during voiding." Children with dysfunctional voiding remain a challenge, and the approach to and management of LUT dysfunction varies widely among programs and providers with the role of pharmacotherapy being ill defined. RECENT FINDINGS: Animated biofeedback is the current treatment modality of choice in children who are not responsive to standard urotherapy. Comprehensive biofeedback programs incorporate continued elimination education, voiding diaries, and home exercises with high success rates...

Tiny Jaarsma, Jan Cameron, Barbara Riegel, Anna Stromberg
PURPOSE OF THE REVIEW: As described in the theory of self-care in chronic illness, there is a wide range of factors that can influence self-care behavior. The purpose of this paper is to summarize the recent heart failure literature on these related factors in order to provide an overview on which factors might be suitable to be considered to make self-care interventions more successful. RECENT FINDINGS: Recent studies in heart failure patients confirm that factors described in the theory of self-care of chronic illness are relevant for heart failure patients...

To support migratory endurance flight, birds accumulate large amounts of fat by hyperphagia (fueling). Whereas the factors influencing migrants' motivation to fuel are well described, the physiological mechanism regulating fueling is largely unknown. Hormones are likely involved and arguably the best studied with respect to food intake and fueling is corticosterone. Corticosterone has a permissive effect, as blocking the hormone's actions prohibits efficient fueling. There are no indications, though that corticosterone stimulates fueling, and some studies even observed negative correlations between corticosterone level and food intake and speed of fueling...

The list of motives by Kanin (1994) is the most cited list of motives to file a false allegation of rape. Kanin posited that complainants file a false allegation out of revenge, to produce an alibi or to get sympathy. A new list of motives is proposed in which gain is the predominant factor. In the proposed list, complainants file a false allegation out of material gain, emotional gain, or a disturbed mental state. The list can be subdivided into eight different categories: material gain, alibi, revenge, sympathy, attention, a disturbed mental state, relabeling, or regret...

The present study was performed to quantitatively examine nurse satisfaction, to investigate the associated factors influencing satisfaction, and to evaluate the effect of improvement measures based on these factors. A survey using the 38-item Chinese version of the Practice Environment Scale (CPPE-38) was performed in a university-affiliated tertiary hospital in Shanghai, China in 2013. Linear regression analysis was performed to screen for associated factors related to each CPPE-3 score and the total satisfaction score...

Undergraduate research is often hailed as a solution to increasing the number and quality of science, technology, engineering, and mathematics graduates needed to fill the high-tech jobs of the future. Student benefits of research are well documented but the emerging literature on advisors' perspectives is incomplete: only a few studies have included the graduate students and postdocs who often serve as research advisors, and not much is known about why research advisors choose to work with undergraduate researchers...

Cues that predict the availability of food rewards influence motivational states and elicit food-seeking behaviors. If a cue no longer predicts food availability, animals may adapt accordingly by inhibiting food seeking responses. Sparsely activated sets of neurons, coined neuronal ensembles, have been shown to encode the strength of reward-cue associations. While alterations in intrinsic excitability have been shown to underlie many learning and memory processes, little is known about these properties specifically on cue-activated neuronal ensembles...

Ghrelin is a stomach-produced hormone that stimulates ingestive behavior and increases motivated behavior to obtain palatable foods. Ghrelin receptors (growth hormone secretagogue receptors; Ghsr) are expressed in the lateral hypothalamic area (LHA), and LHA-targeted ghrelin application increases ingestive behavior in male rodents. However, the effects of LHA ghrelin signaling in females are unexplored. Here we investigated whether LHA ghrelin signaling is necessary and sufficient for control of ingestive and motivated behavior for food in male and female rats...

We examine key study design challenges of using stated-preference methods to estimate the value of whole-genome sequencing (WGS) as a specific example of genomic testing. Assessing the value of WGS is complex because WGS provides multiple findings, some of which can be incidental in nature and unrelated to the specific health concerns that motivated the test. In addition, WGS results can include actionable findings (variants considered to be clinically useful and can be acted on), findings for which evidence for best clinical action is not available (variants considered clinically valid but do not meet as high of a standard for clinical usefulness), and findings of unknown significance...

A clinician-reported outcome (ClinRO) assessment is a type of clinical outcome assessment (COA). ClinRO assessments, like all COAs (patient-reported, observer-reported, or performance outcome assessments), are used to 1) measure patients' health status and 2) define end points that can be interpreted as treatment benefits of medical interventions on how patients feel, function, or survive in clinical trials. Like other COAs, ClinRO assessments can be influenced by human choices, judgment, or motivation. A ClinRO assessment is conducted and reported by a trained health care professional and requires specialized professional training to evaluate the patient's health status...
