Canon law recognizes the pastor as the chief educational officer (CEO) of the parish school. However, recent studies demonstrate that seminaries do not prepare seminarians for work in or leadership of Catholic schools, and recent scholarship also demonstrates that an increasing number of seminarians lack the desire to lead a parish school. Our research study examined the post-seminary preparation of priests for leadership of parish schools. We also explored alternative governance models for Catholic schools. We conducted structured interviews with 10 national leaders to explore these two areas of interest. Our findings demonstrate that preparation of newly ordained and veteran priests for parish school leadership is woefully inadequate. Interviewees suggested that the pastor/principal relationship and school finance are two important topics that should be addressed in best practice preparation programs for school leaders. All 10 interviewees had difficulty imagining alternative governance models for schools in which the pastor would not serve as the CEO, but at the same time, some of the participants could see potential benefits of alternative governance models. Based on the findings of our study, we recommend that: (1) seminary programs include an initial introduction to the importance of Catholic schools for evangelization; (2) a new national model for preparing young and veteran priests for school leadership be developed and implemented; (3) existing best practices for alternative governance models be collated and promulgated; and (4) church leaders and stakeholders determine the best governance models for their schools and then prepare the appropriate people for leadership roles accordingly.

Recognizing that pastors of parishes with a Catholic school play a vital role in Catholic education, and that the seminarians of today will be the parish pastors of tomorrow, this study sought to provide a better understanding of the perceptions held by Catholic seminarians about parish schools. Fourteen seminary students from 12 seminaries and 14 different dioceses from across the United States participated in focus group interviews to discuss their thoughts and perceptions about parish schools. Themes that emerged from focus group discussions included the reinterpretation of the New Evangelization, the understanding of the value of Catholic schools, mixed feelings about leadership of a parish with a school, lack of preparation for school administration, and minimal preparation specific to Catholic schools. Recommendations include the addition of a focus on Catholic schools in new editions of the Program of Priestly Formation (USCCB, 2006) and changes to seminary curricula. [ABSTRACT FROM AUTHOR]

The impact of evolving treatment regimens, airway clearance strategies, and antibiotic combinations on the incidence and prevalence of respiratory infection in cystic fibrosis (CF) in children and adolescents remains unclear. The incidence, prevalence, and prescription trends from 2002 to 2019 with 18,339 airway samples were analysed. Staphylococcus aureus [- 3.86% (95% CI - 5.28-2.43)] showed the largest annual decline in incidence, followed by Haemophilus influenzae [- 3.46% (95% CI - 4.95-1.96)] and Pseudomonas aeruginosa [- 2.80%95% CI (- 4.26-1.34)]. Non-tuberculous mycobacteria and Burkholderia cepacia showed a non-significant increase in incidence. A similar pattern of change in prevalence was observed. No change in trend was observed in infants < 2 years of age. The mean age of the first isolation of S. aureus (p < 0.001), P. aeruginosa (p < 0.001), H. influenza (p < 0.001), Serratia marcescens (p = 0.006) and Aspergillus fumigatus (p = 0.02) have increased. Nebulised amikacin (+ 3.09 ± 2.24 prescription/year, p = 0.003) and colistin (+ 1.95 ± 0.3 prescriptions/year, p = 0.032) were increasingly prescribed, while tobramycin (- 8.46 ± 4.7 prescriptions/year, p < 0.001) showed a decrease in prescription. Dornase alfa and hypertonic saline nebulisation prescription increased by 16.74 ± 4.1 prescriptions/year and 24 ± 4.6 prescriptions/year (p < 0.001). There is a shift in CF among respiratory pathogens and prescriptions which reflects the evolution of cystic fibrosis treatment strategies over time., (© 2024. Crown.)

Patient portals are websites or apps that provide patients with tools to manage healthcare appointments, access their health records, and communicate with clinicians. Patient portals have been demonstrated to be beneficial for improving communication between patients/carers and their healthcare team in a range of health settings. However, there is limited research on the barriers and enablers for implementing patient portals from the perspective of health professionals and healthcare teams, particularly in a paediatric setting. This study aimed to understand healthcare teams' experiences of using a patient portal and, using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework, explore the barriers and enablers to ongoing use. Participants were 11 health professionals participating in the pilot of a patient portal for patients/carers in paediatric care. Data were collected using semi-structured interviews. Analysis of the interview data identified nine themes about implementing a patient portal in paediatric care, all of which aligned with the four constructs of the UTAUT. This study identified that barriers and enablers of the uptake of a patient portal by health professionals in a paediatric context aligned with the UTAUT framework. Value for the patient, improved workflow, and adequate technical and implementation support were highlighted by participants.

Experimental non-human primate models of obesity are induced through the introduction of atypically calorically rich diets. Studies in captive-bred macaques show the development of obesity and diabetes with similar complications to humans including eye and kidney diseases, nerve damage associated with pain and blood vessel damage. Diets differ in outcomes and here we document inflammation of the gastrointestinal tract that can be exacerbated through these dietary interventions. Following baseline physiological evaluation of body composition, Southern pigtail macaques were given a high-fat diet (HFD) for three months. This HFD consisted of lard, grains (including gluten), dairy and fructose that was otherwise omitted from a standard macaque diet (Chow). Physiological parameters were then reassessed before animals were reverted back to standard Chow for a further three months (remission). Consumption of the HFD resulted in food-mediated hypersensitivity marked by chronic weight loss, alopecia, malabsorption, protein-losing enteropathy and gross diffuse intestinal villi atrophy and lamina propria hypertrophy. Physiological changes were more highly pronounced in female macaques suggesting sex-specific differences but could be fully reversed through change of diet. Care should be taken in choosing non-human primate HFD diets for creating experimental models of obesity because they can induce severe food-driven chronic inflammation of the gastrointestinal tract that can eventuate to diet-induced chronic wasting and mortality., Competing Interests: The work presented in our manuscript was partly supported by the National Health and Medical Research Council (NHMRC) of Australia (https://nhmrc.gov.au/) and from a commercial source, NovoNordisk (https://www.novonordisk.com/).

Mutations in the Nkx2-5 gene are a main cause of congenital heart disease. Several studies have addressed the phenotypic consequences of disrupting the Nkx2-5 gene locus, although animal models to date failed to recapitulate the full spectrum of the human disease. Here, we describe a new Nkx2-5 point mutation murine model, akin to its human counterpart disease-generating mutation. Our model fully reproduces the morphological and physiological clinical presentations of the disease and reveals an understudied aspect of Nkx2-5 -driven pathology, a primary right ventricular dysfunction. We further describe the molecular consequences of disrupting the transcriptional network regulated by Nkx2-5 in the heart and show that Nkx2-5 -dependent perturbation of the Wnt signaling pathway promotes heart dysfunction through alteration of cardiomyocyte metabolism. Our data provide mechanistic insights on how Nkx2-5 regulates heart function and metabolism, a link in the study of congenital heart disease, and confirms that our models are the first murine genetic models to our knowledge to present all spectra of clinically relevant adult congenital heart disease phenotypes generated by NKX2-5 mutations in patients., Competing Interests: Conflict of interest: The authors have declared that no conflict of interest exists.

The neuropeptide kisspeptin regulates reproduction by stimulating gonadotropin-releasing hormone (GnRH) neurons via the kisspeptin receptor KISS1R. In addition to GnRH neurons, KISS1R is expressed in other brain areas and peripheral tissues, which suggests that kisspeptin has additional functions beyond reproduction. Here, we studied the energetic and metabolic phenotype in mice lacking kisspeptin signaling (Kiss1r KO mice). Compared with WT littermates, adult Kiss1r KO females displayed dramatically higher BW, leptin levels, and adiposity, along with strikingly impaired glucose tolerance. Conversely, male Kiss1r KO mice had normal BW and glucose regulation. Surprisingly, despite their obesity, Kiss1r KO females ate less than WT females; however, Kiss1r KO females displayed markedly reduced locomotor activity, respiratory rate, and energy expenditure, which were not due to impaired thyroid hormone secretion. The BW and metabolic phenotype in Kiss1r KO females was not solely reflective of absent gonadal estrogen, as chronically ovariectomized Kiss1r KO females developed obesity, hyperleptinemia, reduced metabolism, and glucose intolerance compared with ovariectomized WT females. Our findings demonstrate that in addition to reproduction, kisspeptin signaling influences BW, energy expenditure, and glucose homeostasis in a sexually dimorphic and partially sex steroid-independent manner; therefore, alterations in kisspeptin signaling might contribute, directly or indirectly, to some facets of human obesity, diabetes, or metabolic dysfunction.

In obesity, anorectic responses to leptin are diminished, giving rise to the concept of "leptin resistance." Increased expression of protein tyrosine phosphatase 1B (PTP1B) has been associated with the attenuation of leptin signaling and development of cellular leptin resistance. Here we report that hypothalamic levels of the tyrosine phosphatase TCPTP are also elevated in obesity to attenuate the leptin response. We show that mice that lack TCPTP in neuronal cells have enhanced leptin sensitivity and are resistant to high-fat-diet-induced weight gain and the development of leptin resistance. Also, intracerebroventricular administration of a TCPTP inhibitor enhances leptin signaling and responses in mice. Moreover, the combined deletion of TCPTP and PTP1B in neuronal cells has additive effects in the prevention of diet-induced obesity. Our results identify TCPTP as a critical negative regulator of hypothalamic leptin signaling and causally link elevated TCPTP to the development of cellular leptin resistance in obesity., (Copyright © 2011 Elsevier Inc.

Ecological stoichiometry focuses on the balance between multiple nutrient elements in resources and in consumers of those resources. The major consumers of bacteria in aquatic food webs are heterotrophic and mixotrophic nanoflagellates. Despite the importance of this consumer-resource interaction to understanding nutrient dynamics in the aquatic food web, few data are available addressing the element stoichiometry of flagellate consumers. Ochromonas danica, a mixotrophic bacterivore, was used as a model organism to study the relationships among temperature, growth rate and element stoichiometry. Ochromonas danica was grown in chemostats at dilution rates ranging between 0.03 and 0.10 h(-1) and temperatures ranging between 15 and 28 °C. Cells accumulated elements as interactive functions of temperature and growth rate, with the highest element concentrations corresponding to cells grown at a low temperature and high growth rates. The highest concentrations of elements were associated with small cells. Temperature and growth rate affected the element stoichiometry (as C:N, C:P and N:P) of O. danica in a complex manner, but the growth rate had a greater effect on ratios than did temperature., (© 2010 Federation of European Microbiological Societies.
