En América Latina, los ingenieros agropecuarios egresan y en su mayoría se vinculan a áreas productivas, que se encuentran en territorios rurales, y por lo general constituyen las zonas más vulnerables a la injusticia social, la inequidad y mayor arraigo de prejuicios que se defienden en nombre de las culturas. Estas situaciones de la profesión y de la sociedad, unidas a las grandes problemáticas del mundo agropecuario, donde emerge una nueva ruralidad, demandan una formación profesional diferente, donde los problemas contemporáneos aparezcan con fundamento académico y de igual modo se desarrollen los dispositivos del conocimiento, que resulten suficientes para integrar el quehacer profesional, así como las competencias generales y específicas de la carrera en la formación de un ser humano enriquecido en sus valores y con un alto grado de profesionalidad.Palabras claves: epistemología, currículo, ingeniería agropecuaria ABSTRACTIn Latin America, agricultural engineers graduate and most of them are linked to productive areas, which are located in rural territories, and are usually the areas most vulnerable to social injustice, inequity and greater rooting of prejudices that are defended in Name of cultures.

Nerve transfer versus muscle transfer to restore elbow flexion after pan–brachial plexus injury: a cost-effectiveness analysis
Authors: Wali Arvin R. , Santiago-Dieppa David R. , Brown Justin M. , Mandeville Ross 
Published: July 2017

OBJECTIVEPan–brachial plexus injury (PBPI), involving C5–T1, disproportionately affects young males, causing lifelong disability and decreased quality of life. The restoration of elbow flexion remains a surgical priority for these patients. Within the first 6 months of injury, transfer of spinal accessory nerve (SAN) fascicles via a sural nerve graft or intercostal nerve (ICN) fascicles to the musculocutaneous nerve can restore elbow flexion. Beyond 1 year, free-functioning muscle transplantation (FFMT) of the gracilis muscle can be used to restore elbow flexion. The authors present the first cost-effectiveness model to directly compare the different treatment strategies available to a patient with PBPI. This model assesses the quality of life impact, surgical costs, and possible income recovered through restoration of elbow flexion.METHODSA Markov model was constructed to simulate a 25-year-old man with PBPI without signs of recovery 4.5 months after injury. The management options available to the patient were SAN transfer, ICN transfer, delayed FFMT, or no treatment. Probabilities of surgical success rates, quality of life measurements, and disability were derived from the published literature. Cost-effectiveness was defined using incremental cost-effectiveness ratios (ICERs) defined by the ratio between costs of a treatment strategy and quality-adjusted life years (QALYs) gained. A strategy was considered cost-effective if it yielded an ICER less than a willingness-to-pay of $50,000/QALY gained. Probabilistic sensitivity analysis (PSA) was performed to address parameter uncertainty.RESULTSThe base case model demonstrated a lifetime QALYs of 22.45 in the SAN group, 22.0 in the ICN group, 22.3 in the FFMT group, and 21.3 in the no-treatment group. The lifetime costs of income lost through disability and interventional/rehabilitation costs were $683,400 in the SAN group, $727,400 in the ICN group, $704,900 in the FFMT group, and $783,700 in the no-treatment group. Each of the interventional modalities was able to dramatically improve quality of life and decrease lifelong costs. A Monte Carlo PSA demonstrated that at a willingness-to-pay of $50,000/QALY gained, SAN transfer dominated in 88.5% of iterations, FFMT dominated in 7.5% of iterations, ICN dominated in 3.5% of iterations, and no treatment dominated in 0.5% of iterations.CONCLUSIONSThis model demonstrates that nerve transfer surgery and muscle transplantation are cost-effective strategies in the management of PBPI. These reconstructive neurosurgical modalities can improve quality of life and lifelong earnings through decreasing disability.
Resection of complex occipital arteriovenous malformation with giant varix: demonstration of microsurgical technique
Authors: Ocak Pinar Eser , Dinc Cem , Cikla Ulaş , Başkaya Mustafa K. 
Published: July 2017

The complexity of arteriovenous malformations (AVMs) does not necessarily preclude surgical resection. In this video the authors present a 72-year-old male who was known to have an occipital AVM with a large draining varix for the previous 10 years. The patient had progressively worsening visual and cognitive deficits over several years. Total surgical resection was achieved following single stage preoperative embolization. Although resection of the AVMs is challenging, even in experienced hands, it offers a cure and may improve patient clinical outcome.The video can be found here: https://youtu.be/YI1AwGjJdvo.

Published: July 2017

The recommendation for the great majority of high-grade brain arteriovenous malformations (bAVMs) is observation, except for those patients with recurrent hemorrhages, progressive neurological deficits, steal-related symptoms, or AVM-related aneurysms, for whom intervention should be considered. These are general recommendations, and the decision should be made on an individual basis. Surgical resection of an AVM in the central lobe may cause postoperative sensorimotor deficits since this anatomical region includes the pre- and postcentral gyri on the lateral surface and the paracentral lobule on the medial surface.The authors present a patient with a ruptured high-grade bAVM in the central lobe who underwent previous surgery for hematoma evacuation and previous radiosurgery, and whose indication for reoperation was proposed based on progressive hemiparesis. Microsurgical resection was possible after a wide frontoparietal craniotomy, which made all the nidus borders accessible. This case illustrates the anatomy and surgical technique for large nidus AVMs in eloquent areas, showing that complete microsurgical resection is possible with good clinical outcome.The video can be found here: https://youtu.be/Cpd1PK6BLIM.

The authors demonstrate the case of a 16-year-old girl with a large symptomatic occipital arteriovenous malformation (AVM). The staged embolization was performed to downgrade the AVM from Spetzler-Martin (S-M) Grade IV (Supplementary S-M Grade 7) to Grade III (Supplementary S-M Grade 5). The patient developed a subacute progressive visual field defect after the final time of embolization. MRI revealed an enlarged draining venous ectasia of the AVM compressing the visual cortex. Postoperatively, good radiological results were achieved, and the patient reported an improvement in her symptoms. The detailed operative technique and surgical nuances (including the surgical features of the AVM postembolization) of the marginal dissection and removal are illustrated in this video atlas.The video can be found here: https://youtu.be/2MZq5patcJI.
Surgical treatment of a complex Grade III Spetzler-Martin posterior temporal arteriovenous malformation
Authors: Chiluwal Amrit , Dehdashti Amir R. 
Published: July 2017

Grade III Spetzler-Martin arteriovenous malformations (AVMs) are a distinct subgroup of brain AVMs. Their variety in terms of location, type of venous drainage, and size makes them the most heterogenous group in the AVM classification. The surgical risk of treatment is also variable depending on the specifics of a given Grade III AVM. In this video illustration, the authors describe the technical nuances of surgical resection of a very complex Grade III left posterior temporal AVM. According to supplementary grading, the unruptured aspect and patient age give this lesion a Grade III; therefore, the combined grading gives the patient a score of 6, which puts him at moderate risk of morbidity for surgery. The indication for surgery was based on the patient’s young age, lifetime risk of hemorrhage, and the location of the AVM in the left inferior/posterior temporal gyrus.The patient underwent 2 sessions of preoperative embolization of the posterior cerebral artery and the external carotid artery feeders prior to craniotomy. The day after the second embolization, the patient was operated on via a posterior temporobasal craniotomy. The dural supply attached to the draining vein was left intact during the dural exposure. The detail of the AVM resection is described in the video clip. A total resection was achieved, and the patient’s neurological examination was intact after the procedure.The video can be found here: https://youtu.be/fj5Cxw3kpXQ.

BackgroundThe oral mucosa is an important defense barrier to penetration of microorganisms. Thus, changes in the oral epithelium might indicate risk for infection in intensive care patients receiving mechanical ventilation.ObjectiveTo evaluate the oral mucosa of intensive care patients who did or did not receive mechanical ventilation by using liquid-base exfoliative cytology.MethodsThe sample consisted of 3 groups: 27 patients admitted to intensive care during a 7- to 14-day period who received mechanical ventilation, 29 patients admitted during the same period who did not receive mechanical ventilation, and 27 healthy patients who had no lesions in the mouth. For all 3 groups, samples were collected from the buccal mucosa by using cytology brushes. Smears were applied to glass slides before Papanicolaou staining and were codified for blind analyses by a cytopathologist. Kruskal-Wallis and Dunn tests were used to analyze the results.ResultsPatients receiving mechanical ventilation had higher prevalence and intensity of karyomegaly, perinuclear halos, cell keratinization, deep cells, and leukocyte infiltrates than did patients in the other 2 groups (P &lt; .05). No significant differences were observed between the control group and the group who did not receive mechanical ventilation.ConclusionsLiquid-base exfoliative cytology can be used to detect preclinical alterations in the oral mucosa. Patients treated with mechanical ventilation are vulnerable to infections, and oral care may be valuable in their prognosis.

Abstract. Deliberate injection of aerosol particles into the stratosphere is a potential climate engineering scheme. Particles injected into the stratosphere would scatter solar radiation back to space, thereby reducing the temperature at the Earth's surface and hence the impacts of global warming. Minerals such as TiO2 or SiO2 are among the potentially suitable aerosol materials for stratospheric particle injection due to their greater light-scattering ability than stratospheric sulfuric acid particles. However, the heterogeneous reactivity of mineral particles towards trace gases important for stratospheric chemistry largely remains unknown, precluding reliable assessment of their impacts on stratospheric ozone, which is of key environmental significance. In this work we have investigated for the first time the heterogeneous hydrolysis of ClONO2 on TiO2 and SiO2 aerosol particles at room temperature and at different relative humidities (RHs), using an aerosol flow tube. The uptake coefficient, γ(ClONO2), on TiO2 was ∼ 1.2 × 10−3 at 7 % RH and remained unchanged at 33 % RH, and increased for SiO2 from ∼ 2 × 10−4 at 7 % RH to  ∼ 5 × 10−4 at 35 % RH, reaching a value of  ∼ 6 × 10−4 at 59 % RH. We have also examined the impacts of a hypothetical TiO2 injection on stratospheric chemistry using the UKCA (United Kingdom Chemistry and Aerosol) chemistry–climate model, in which heterogeneous hydrolysis of N2O5 and ClONO2 on TiO2 particles is considered. A TiO2 injection scenario with a solar-radiation scattering effect very similar to the eruption of Mt Pinatubo was constructed. It is found that, compared to the eruption of Mt Pinatubo, TiO2 injection causes less ClOx activation and less ozone destruction in the lowermost stratosphere, while reduced depletion of N2O5 and NOx in the middle stratosphere results in decreased ozone levels. Overall, no significant difference in the vertically integrated ozone abundances is found between TiO2 injection and the eruption of Mt Pinatubo. Future work required to further assess the impacts of TiO2 injection on stratospheric chemistry is also discussed.
Learning From Nature: The Rational Non‐Centrosymmetric Structural Design in the Honeycomb‐Like Gaudefroyite Family

Published: October 2024

AbstractNon‐centrosymmetric (NCS) structures are of great importance for the development of symmetry‐dependent functional properties, yet their rational structural design remains a great challenge. Herein, a strategy driven by a highly promising honeycomb structure framework that draws from nature has been proposed for designing three new NCS structures, La4O4(BO3)3·ClSr3 and Sr2Y(BO3)4·XSr3 (X = Cl, Br). They exhibit excellent nonlinear optical (NLO) properties, including strong second‐harmonic‐generation (SHG) responses (2.4–5.4 × KH2PO4 (KDP)), short ultraviolet (UV) cut‐off edges (λcut‐off < 200 nm), and stable physicochemical properties, which make them promising UV NLO crystals. Furthermore, comparing their structures and properties with other compounds in the Gaudefroyite family, it has been found that they all have honeycomb‐like structures. With the continuous modification of their compositions, these structures can achieve not only structural transformation from centrosymmetric (CS) to NCS but also gradual doubling of SHG responses from Ba4(BO3)3X4·XBa3 series (≈1 × KDP) to Sr2Y(BO3)4·XSr3 series (≈2 × KDP) to La4O4(BO3)3·ClSr3 series (≈6 × KDP). Moreover, the ON–OFF of their chiral structures can be achieved through modulating a honeycomb‐like framework and their infilling as observed in La4O4(BO3)3·BrBa3 (P63mc), La4O4(BO3)3·ClSr3 (P63) and Sr2Y(BO3)4·ClSr3 (P63mc). These indicate that honeycomb is an ideal structural template for achieving the design of NCS structures.
