Estrategias de estudio y trabajo en estudiantes universitarios de la UIB

El estudio se centra en el conocimiento de los procesos de aprendizaje que se desarrollan en la enseñanza superior, siendo su objetivo principal la evaluación de las estrategias de aprendizaje utilizadas por estudiantes universitarios a lo largo de su formación inicial. Responde a un diseño descriptivo-exploratorio, dirigido a las estrategias de estudio y trabajo de la población universitaria de la Universidad de las Islas Baleares (UIB). Para ello, se procedió a la elaboración de un cuestionario como instrumento de recogida de datos1 sobre estrategias de estudio y trabajo, categorizado en cuatro grupos de estrategias (disposicionales y de apoyo; de búsqueda, recogida y selección de información; de procesamiento y uso de información; metacognitivas, de regulación y control) y sus correspondientes subcategorías. Se trabajó con una muestra de 949 estudiantes de la UIB, clasificados por ámbitos disciplinares y estudios, agrupados en grandes dimensiones (sexo; estudios de ciclo corto y de ciclo largo; rama de estudios; dedicación al estudio y actividad laboral), aportando, para cada una de ellas los datos estadísticos en los que se constata una diferencia significativa.L’estudi està centrat en el coneixement dels processos d’aprenentatge que es desenvolupen a l’ensenyament superior, i el l’objectiu principal és l’avaluació de les estratègies d’aprenentatge utilitzades per estudiants universitaris al llarg de la seva formació inicial.

This is a response to a descriptive-exploratory design addressed to the learning and working strategies among the students of the University of the Balearic Islands (UIB). Regarding to this, a question paper was designed as a tool for the collection of data on the studying and working strategies sorted by four strategy groups (dispositional and backup groups; research, collection and selection of information; processing and use of information; metacognitive, regulation and control groups) with their respective subcategories. We took a sample of 949 students from the UIB, sorted by study and disciplinary areas, and we gathered them in larger-dimension groups (gender, shorter and longer degrees, field of study and commitment to studies and work). These groups provided, for each of the samples, statistical information in which an important difference is stated

Normosmic Congenital Hypogonadotropic Hypogonadism Due to TAC3/TACR3 Mutations: Characterization of Neuroendocrine Phenotypes and Novel Mutations

CONTEXT: TAC3/TACR3 mutations have been reported in normosmic congenital hypogonadotropic hypogonadism (nCHH) (OMIM #146110). In the absence of animal models, studies of human neuroendocrine phenotypes associated with neurokinin B and NK3R receptor dysfunction can help to decipher the pathophysiology of this signaling pathway. OBJECTIVE: To evaluate the prevalence of TAC3/TACR3 mutations, characterize novel TACR3 mutations and to analyze neuroendocrine profiles in nCHH caused by deleterious TAC3/TACR3 biallelic mutations. RESULTS: From a cohort of 352 CHH, we selected 173 nCHH patients and identified nine patients carrying TAC3 or TACR3 variants (5.2%). We describe here 7 of these TACR3 variants (1 frameshift and 2 nonsense deleterious mutations and 4 missense variants) found in 5 subjects. Modeling and functional studies of the latter demonstrated the deleterious consequence of one missense mutation (Tyr267Asn) probably caused by the misfolding of the mutated NK3R protein. We found a statistically significant (p<0.0001) higher mean FSH/LH ratio in 11 nCHH patients with TAC3/TACR3 biallelic mutations than in 47 nCHH patients with either biallelic mutations in KISS1R, GNRHR, or with no identified mutations and than in 50 Kallmann patients with mutations in KAL1, FGFR1 or PROK2/PROKR2. Three patients with TAC3/TACR3 biallelic mutations had an apulsatile LH profile but low-frequency alpha-subunit pulses. Pulsatile GnRH administration increased alpha-subunit pulsatile frequency and reduced the FSH/LH ratio. CONCLUSION: The gonadotropin axis dysfunction associated with nCHH due to TAC3/TACR3 mutations is related to a low GnRH pulsatile frequency leading to a low frequency of alpha-subunit pulses and to an elevated FSH/LH ratio. This ratio might be useful for pre-screening nCHH patients for TAC3/TACR3 mutations

Ventilation and outcomes following robotic-assisted abdominal surgery: an international, multicentre observational study

Background: International data on the epidemiology, ventilation practice, and outcomes in patients undergoing abdominal robotic-assisted surgery (RAS) are lacking. The aim of the study was to assess the incidence of postoperative pulmonary complications (PPCs), and to describe ventilator management after abdominal RAS. Methods: This was an international, multicentre, prospective study in 34 centres in nine countries. Patients ≥18 yr of age undergoing abdominal RAS were enrolled between April 2017 and March 2019. The Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score was used to stratify for higher risk of PPCs (≥26). The primary outcome was the incidence of PPCs. Secondary endpoints included the preoperative risk for PPCs and ventilator management. Results: Of 1167 subjects screened, 905 abdominal RAS patients were included. Overall, 590 (65.2%) patients were at increased risk for PPCs. Meanwhile, 172 (19%) patients sustained PPCs, which occurred more frequently in 132 (22.4%) patients at increased risk, compared with 40 (12.7%) patients at lower risk of PPCs (absolute risk difference: 12.2% [95% confidence intervals (CI), 6.8–17.6%]; P&lt;0.001). Plateau and driving pressures were higher in patients at increased risk, compared with patients at low risk of PPCs, but no ventilatory variables were independently associated with increased occurrence of PPCs. Development of PPCs was associated with a longer hospital stay. Conclusions: One in five patients developed one or more PPCs (chiefly unplanned oxygen requirement), which was associated with a longer hospital stay. No ventilatory variables were independently associated with PPCs. Clinical trial registration: NCT02989415
