Controlled release urea fertilizer is one solution to increase the efficiency of nutrient absorption by plants and is more environmentally friendly. The aims of this study was to determine the yield and water absorption of controlled release urea fertilizer and analyze the content of nitrate, nitrite, and ammonia as environmental pollution parameters. Controlled release urea fertilizer was prepared using the emulsion crosslinking method with chitosan as the matrix. Urea was dissolved in chitosan then added in oil and stirred to form an emulsion. Next, glutaraldehyde saturated toluene (GST) as a crosslinker was dripped slowly and then continuously stirred for 2 hours. Urea loaded-chitosan microspheres (controlled release urea fertilizer) were dried and analyzed. Furthermore, the yield, water absorption, and analysis of nitrate, nitrite, and ammonia from the released urea was determined. Controlled release urea fertilizer obtained yield was 91.3–97.28%, water absorption of 78.87–91.61%. Analysis of nitrate, nitrite, and ammonia from the study concluded that urea fertilizer contained in chitosan microspheres is more environmentally friendly.

Revisión integral de hemoptisis
Authors: Watson Hernández Rebeca , Morales Roldán Laura 
Published: August 2022

La hemoptisis es la expectoración de sangre proveniente del árbol traqueobronquial. Se clasifica en hemoptisis masiva o amenazante para la vida y no amenazante, dependiendo del volumen de sangrado, su velocidad y la reserva cardiopulmonar. Predomina en hombres mayores de 62 años. Su principal diagnóstico diferencial es la pseudohemoptisis cuyo origen puede ser del tracto respiratorio superior, que se considera en casos en los cuales hubo previas molestias nasofaríngeas como sangre roja proveniente de la boca sin mayor esfuerzo, o gastrointestinal que se caracteriza por hematemesis oscura, con sangre desoxigenada y en ocasiones con restos alimentarios. En este caso existen antecedentes de cirrosis y úlceras. La etiología de la hemoptisis es multifactorial, tanto de alteraciones de vía aérea, parenquimatosas, vasculares como iatrogénicas. Para lograr un diagnóstico adecuado, hay que abordar al paciente con una adecuada historia clínica, examen físico y complementar con estudios de imagen para poder determinar con exactitud el sitio y causa de sangrado. De esta forma se logrará ofrecer un tratamiento dirigido y oportuno.
Expresión clínica e histológica de los tumores del ángulo pontocerebeloso
Authors: Badilla Nelson Annekey 
Published: August 2022

El área del ángulo pontocerebeloso es un espacio virtual localizado en la fosa posterior de la cavidad craneal, en ella se contienen varias estructuras anatómicas funcionales como los pares craneales; el séptimo par (facial) encargado en su porción sensitiva y motora de la musculatura facial y la percepción en el gusto en sus 2/3 anteriores y el octavo par (vestíbulo coclear) que se encarga de producir la audición y equilibrio. A su vez limita con otras estructuras de vital importancia como lo es el tronco encefalico estructura que contiene varios núcleos asi como el centro de la respiración y cardiovascular, el cuarto ventrículo que es un área de flujo de líquido cefalorraquideo hacia la medula y el cerebelo encargado de la coordinación de movimientos y parte del equilibrio. Si bien es cierto que múltiples procesos tanto tumorales como no tumorales pueden afectar dichas estructuras, son los tumorales los que confieren mayor importancia debido a su potencial destructivo de estructuras vecinas, capacidad de expansión que genera compresión y establecimiento de siembras que pueden metastatizar a otras estructuras locales y distantes. Las manifestaciones clinicas secundarias a la afección en dicha área van a depender del sitio donde estas empiecen a crecer asi como su tamaño, siendo que inicialmente la clinica más frecuente es el tinnitus y pérdida auditiva unilateral, desequilibrio y nistagmo, ya más tardíamente hay compromiso de otros pares craneales afectando la sensibilidad facial, la percepción del gusto e hidrocefalia por obstrucción. Para su diagnóstico amerita una adecuada correlación anatómica que permita orientar los estudios de imagen que definen bien las estructuras y permiten plantear un abordaje, pero es solo el estudio histológico quien nos da un diagnóstico final y como tal un pronóstico.
Assessment of neurosurgical resident milestone evaluation reporting and feedback processes
Authors: Clarke Michelle J. , Frimannsdottir Katrin 
Published: August 2022

OBJECTIVE
Structured performance evaluations are important for the professional development and personal growth of resident learners. This process is formalized by the Accreditation Council for Graduate Medical Education milestones assessment system. The primary aim of this study was to understand the current feedback delivery mechanism by exploring the culture of feedback, the mechanics of delivery, and the evaluation of the feedback itself.

METHODS
Face-to-face interviews were conducted with 10 neurosurgery residents exploring their perceptions of summative feedback. Coded data were analyzed qualitatively for overriding themes using the matrix framework method. A priori themes of definition of feedback, feedback delivery, and impact of feedback were combined with de novo themes discovered during analysis.

RESULTS
Trainees prioritized formative over summative feedback. Summative and milestone feedback were criticized as being vague, misaligned with practice, and often perceived as erroneous. Barriers to implementation of summative feedback included perceived veracity of feedback, high interrater variability, and the inconstant adoption of a developmental progression model. Gender bias was noted in degree of feedback provided and language used.

CONCLUSIONS
Trainee perception of feedback provided multiple areas of improvement. This paper can serve as a baseline to study improvements in the milestone feedback process and optimize learning.

Authors: Zaed Ismail , Bongetta Daniele , Della Pepa Giuseppe Maria , Zoia Cesare , Somma Teresa , Zoli Matteo , Raffa Giovanni , Menna Grazia 
Published: August 2022

OBJECTIVE
Imposter syndrome (IS) occurs when high-achieving individuals have a pervasive sense of self-doubt combined with fear of being exposed as a fraud, despite objective measures of success. This is one of the main causes of burnout among professionals, threatening their mental health and general well-being. The prevalence and severity of IS among neurosurgery residents and young neurosurgeons has not been yet studied. The primary outcomes of this study were the prevalence and severity of IS.

METHODS
An anonymous cross-sectional survey including both a demographic questionnaire (Clance Imposter Phenomenon Survey) and compensatory mechanisms was distributed to young neurosurgeons and residents in neurosurgery in Italy.

RESULTS
A total of 103 responses were collected. The prevalence rate was 81.6%. Among the respondents with IS, 42.7% showed moderate signs, 27.2% frequent, and only 11.7% had an intense symptomatology. Level of education, female sex, and academic achievements were all identified as predictive factors of IS.

CONCLUSIONS
A total of 81.6% of respondents reported potentially significant levels. The implications of IS on both the outcomes in patients and the well-being of neurosurgeons should be evaluated in future studies.
