This chapter aims to review the tech evolution in hospitality, from services to eServices, that will provide hyper-personalization in the hospitality field. In the past, the services were provided by hotels through diligent staff and supported by standardized and weak technology that was not allowed to provide personalized services by itself. Therefore, the study applied K-means and FCM clustering algorithms to cluster online travelers' reviews from TripAdvisor. The study shows that K-means clustering outperforms fuzzy c-means in this study in terms of accuracy and execution time while fuzzy c-means converge faster than K-means clustering in terms of the number of iterations. K-means achieved 93.4% accuracy, and fuzzy c-means recorded 91.3% accuracy.

Published: January 2022

Deep learning has attracted more and more attention in speech recognition, visual recognition and other fields. In the field of image processing, using deep learning method can obtain high recognition rate. In this paper, the convolution neural network is used as the basic model of deep learning. The shortcomings of the model are analyzed, and the DBN is used for the image recognition of diseases and insect pests. In the experiment, firstly, we select 10 kinds of disease and pest leaves and 50000 normal leaves, each of which is used for the comparison of algorithm performance.In the judgment of disease and pest species, the algorithm proposed in this study can identify all kinds of diseases and insect pests to the maximum extent, but the corresponding software (openCV, Access) recognition accuracy will gradually reduce along with the increase of the types of diseases and insect pests. In this study, the algorithm proposed in the identification of diseases and insect pests has been kept at about 45%.

Published: January 2022

The water temperature distribution and spatio-temporal variation law of the reservoir have a great influence on the water quality and ecological environment of the reservoir, and it is also an important temperature boundary condition for the design of concrete dam of hydropower station project, which is of great significance for the optimal design and operation of the reservoir. There are many factors affecting the water temperature of the reservoir, and it is difficult to predict the water temperature distribution accurately because of the lack of data and experience. In this paper, a numerical analysis model is established for the reservoir of a hydropower station on the Nam Ngum in Laos, and the water temperature of the reservoir is calculated and predicted, and the water temperature distribution in the reservoir and the water temperature distribution in front of the dam are analyzed and discussed. The results show that the solar shortwave radiation is the main factor affecting the temperature stratification of the reservoir. The stable low temperature layer of the reservoir is not obvious, but there is a tendency to form stratification. The research results can provide water temperature value for the design of concrete dam of the hydropower station and provide reference for the prediction of the water temperature of other similar reservoirs.

Coordinate technologies play an important role in many industrial applications, especially for eco nanobuildings and spaces. Lately, the global new architecture seems to be more automated as appeared in the parametric architecture, topological, animate, metamorphic, and isomorphic and per formative architecture. They all depend on the visualization, the high precision techniques, and the 4th dimension all within sustainability. But till now, there is no main environmental space code, unit or standards to deal with to insure that the environmental design became in a form of an easier one to be the design of the era as all the global calls aware us to preserve the nature from pollution. Mainly within the call for the nanotechnology, if there is found a least architectural volumetric unit which can fulfill all the environmental sustainable systems within the visionary and the 4th dimensional acts, then we can act with the environment with easier spaces that can be duplicated in a uniform way, to work easily for measure and estimate the budget of his supposed built space. Therefore, the main liable issue concerns the research for the least architectural volumetric unit, and we can call it the nanoarchitectural unit. As nanoarchitecture is a virtual and proposed kind of architecture, which the architects aim to create it or follow it the nanotechnology to insure that the 3D technology is to submit as an application in all branches of science, to achieve a dream of the present-day from sustainability and environment for future generations. Accordingly, recent studies have confirmed that 3D coordinate technology using digital printing has an important subtle impact on industry, especially for green buildings and spaces.
An Effective Designing of Supercapacitor Mitigating Self-Discharge
Authors: Zhang Si Meng
Published: January 2022

Supercapacitor is a kind of effective energy storage device with merits such as high power density, long cycling life and so on, but their application is limited nowadays compared to the application of batteries. One important restriction is because of the serious self-discharge in supercapacitors, and how to conquer the self-discharge problem is an important issue. In this article we propose an effective way to reduce self-discharge of the supercapacitor by carefully designing of activated carbon (ACs) electrodes and water-in salt electrolyte. The electrochemical characterization shows that our supercapacitor can have the ability to reduce self-discharge.

Authors: Yang Rong , Zhao Chun Rong , Kan Su Rong , Yuan Min Juan
Published: January 2022

Carbon coated lithium titanate (Li4Ti5O12/C) was obtained by a facile solid state approach in inert Ar atmosphere. The composition, morphology, residual carbon content and Ti valence of the samples were systematically investigated. The carbon content of Li4Ti5O12/C should be optimized, since excess carbon in the composite leads to the reduction of Ti (IV) to form Ti (III), which results in large irreversible capacity of Li4Ti5O12/C. With an optimal carbon content of 0.68wt%, the Li4Ti5O12/C sample shows high rate capabilities and good cycling ability, delivering discharge capacities of 160.8 mAh/g at 5C. The superior high rate properties are ascribed to the specific nanostructures, which enables fast electronic and ionic transport by introducing carbon coating and decreasing the particle size of lithium titanate.

Published: January 2022

2024Al alloy powder as matrix material with nanocopper-modified graphene as reinforcement was studied to explore the effects of graphene on the tissue, hardness, friction performance of the composite. The Cu/Gr/2024Al composites were prepared via three-dimensional mixed powder and vacuum hot press sintering. The results found that the nanocopper-modified graphene could be uniformly distributed in the aluminum alloy matrix, and formed a good binding interface with the matrix material. When the graphene content was 0.75 wt.% and 1.0wt%, the impact yield strength and the hardness reached the maximum of 434.8 MPa and 118.4 HV5, which were 27.24% and 43.11% higher than that of 2024Al respectively. Furthermore, with the increase of nanocopper-modified graphene content, the corrosion resistance of composite materials in 3.5%Cl-concentration solution was improved.

Authors: Wang Hui , Hou Cong Ying , Bai Yan
Published: January 2022

The effect of bentonite (BT) on the structure and performance of sodium alginate (SA) as microsphere carrier of essential oil is studied. The addition of BT can improve the performance of alginate gel microspheres through the study of the properties of single carrier SA and composite carrier SA/BT. The experimental results show that the viscosity of composite carrier SA/BT solution is higher than that of carrier SA solution, and the increasing rate of viscosity of composite solution with temperature is less than that of SA. The addition of BT can effectively inhibit the swelling of SA microspheres. The hydrogen bonding between SA and BT is shown in FTIR, and the interlayer spacing of BT crystal structure is not changed in XRD analysis. The mass loss rate of SA/BT microspheres is lower than that of SA in TGA analysis. The more dense structure of SA/BT microspheres than that of SA microspheres is confirmed by SEM. The release rate of cinnamon oil in SA/BT gel microspheres is significantly lower than that in SA gel microspheres under different temperature conditions. The addition of BT could better control the volatilization of essential oil encapsulated in SA gel microspheres.
The Adsorption and Regeneration of Magnetic Modified Bentonite Composite for Dye Wastewater
Authors: Jiang Bo , Feng Shang Hua , Zhang Jian Ping
Published: January 2022

Bentonite has strong adsorption for cationic dyes. But as dye absorbent, it's difficult for them to recycle and regenerate. In order to solve these problems, a kind of magnetism bentonite composite was prepared by coprecipitation method, and H2O2/UV process was attempted to regenerate the spent composite. The results showed that the composite still has high adsorption performance for cationic dye methylene blue (MB), and the introduction of magnetite can achieve rapid solid-liquid seperation of composite in the external magnetic field. For the spent composite, its adsorption performance could be recovered by H2O2/UV process. The recovery effect is directly related to the dosage of hydrogen peroxide. In this study, as the dosage of hydrogen peroxide was 3% (volume ratio), the adsorption efficiency of spent composite for MB could almost return to its initial level after 3h regeneration. This research is of great significance to improve the utilization of bentonite adsorbent in water treatment engineering, and can also provide technical reference for the recycle and regeneration of other adsorbent materials.

Authors: Feng Lu Lu , Qiao Wei Wen , Sun Jian , Li De Fa , Li Ping Ping , Cao Tian Dong
Published: January 2022

The continuous cooling transformation behavior of high-carbon pearlitic steel was studied by employing optical microscopy, scanning electron microscopy, and the Vickers hardness test. The results show that the microstructure of the test steel is composed of proeutectoid cementite and lamellar pearlite in the cooling rate range of 0.05–2 °C/s and lamellar pearlite in the range of 2–5 °C/s. Further, martensite appears at 10 °C/s. With the increase in the cooling rate, the Vickers hardness of the test steel first decreases and then increases. In the industrial production of high-carbon pearlite steel, the formation of proeutectoid cementite at a low cooling rate needs to be avoided, and at the same time, the formation of martensite and other brittle-phase at a high cooling rate needs to be avoided.

Published: January 2022

In this paper, we have studied the EPR spectra, X-ray diffraction and Raman Analysis, Microstructures-morphology of the Ceria NPs calcined at different temperatures of 700 °C, 850 °C ,these materials have been synthesized by Co precipitation (CPT) method by using Cerium tri-nitrate hexahydrate and potassium carbonate solutions. Then synthesized precipitate was heated at 70 °C for 20 hour. Slow grinding of the precipitate and calcined for 3 hours at different temperatures viz. 700 °C and 850 °C to form fine Cerium oxide powder-Ceria NPs. The EPR measurements were made using continuous wave spectrometer (X-band, Bruker Biospin EMX Plus). The g values were obtained by using diphynelpirichylhydrageyl (DPPH-C18H12N5O6) sample and got g value is around 1.97. This g tensor is decreased when the calcined temperature are increased, EPR parameters are also changed as the calcined temperature increases. When the calcined temperature is increased from 700 °C to 850 °C, a doublet separated, intensity increased. The X-Ray diffraction pattern shows the nature of the Ceria NPs crystal, with a cubic structure and got the lattice parameters 5.392 Å for samples calcined at temperature of 700 °C and 5.357 Å at 850 °C which shows decreasing trend in lattice parameter with calcination temperature. The intensity of Raman peaks is also shifted upwards with a rise in temperature. This intensity difference could be because of the rise in vibrational amplitudes of the closest neighboring bonds because of the increase in particle size 11.3± 1.0 to 15.6± 1.0 nm at calcination temperatures of 700 °C and 850 °C and the Raman peak of peak I, 461 cm-1 and peak II, 463 cm-1 respectively. Other peaks were not observed in this Raman pattern. The EDS analysis confirms the presence of the Ce and O atoms in the synthesized samples. Spherical shapes and homogeneously distributed Ceria NPs and a rather tendency for agglomeration were confirmed.

Published: January 2022

Present studies are based on adding ferrochrome slag as reinforcement in AA 7075 alloy manufactured via the stir casting process. Two different slag particles are chosen; they are 36μm (Micro) and 68 nm (Nano). This was added to evaluate the size effects in the given alloy matrix. The composites were tested for unique microstructural properties and mechanical properties. The results Revealed uniform particle distribution within the matrix and good bonding between the matrix and the reinforcement. Better mechanical properties are obtained for both micro and nanocomposites than base alloy. This is further enhanced by ageing treatments. nanocomposites show superior mechanical properties than either alloy or micro composite. Interestingly, nanocomposite exhibits an increase in strength with good ductility; same is confirmed with fracture studies.

Published: January 2022

The flexural behavior of Incinerated Bio-Medical Waste Ash (IBWA) – Ground Granulated Blast Furnace Slag (GGBS) based Reinforced Geopolymer Concrete (RGPC) beams with Waste Glass Powder (WGP) as fine aggregate is explored in this research. The fine aggregate (M-Sand) is substituted by varying the waste glass powder as 0 percent, 5 percent, 10 percent, 15 percent, 20 percent, 25 percent, 30 percent, 35 percent, 40 percent, 45 percent, and 50 percent, and the mixture is cured under atmospheric curing. The impact of the WGP weight percentage on the flexural behavior of GPC beams is analyzed. The conduct of RGPC beams varies from that of ordinary Portland Concrete (OPC) beams, which is defined and examined. Deflection, ductility factor, flexural strength, and toughness index were measured as flexural properties for beams. In contrast to the reference beams, the RGPC beams containing 50% Waste Glass Powder as fine aggregate demonstrated a major increase in cracking resistance, serviceability, and ductility, according to the experimental finding. The RGPC beam without WGP ended in failure with a brittle manner whereas those beams with WGP encountered ductile failure. The RGPC beams' load ability improved by up to 50% as the weight percentage of WGP was enhanced.

Authors: Meena Ugan , Gupta Ashok , Sinha Virendra
Published: January 2022

Background: Traumatic brain injury (TBI) is the leading cause of deaths worldwide. The morbidity and mortality due to TBI are related to both primary as well as secondary insults. The patients who survive from the primary insults, some may still have long-term disabilities. Most of these outcomes are related to the high incidence of prehospital secondary brain insults. Knowledge of these variables and timely management of the disease at the prehospital level can significantly improve the outcome and decrease the mortality. Aims: The present study is aimed to evaluate the current status of prehospital care, prehospital factors, epidemiological characteristics, and outcome of TBI patients at a Level 1 trauma center. Material and Methods: It is a prospective observational study of 830 cases of TBI, done from November 15, 2015, to March 15, 2016, in the Department of Neurosurgery, Institute of Traumatology, SMS Medical College, Jaipur, Rajasthan, India. Results: Analysis of data revealed that the incidence of TBI in males is four times higher than females. Most patients are in the age group of 21–30 years (30.24%) followed by 31–40 years (18.55%). Road traffic injury (69.52%) is the most common mode of injury in the age group of 21–30 years followed by injury due to fall (22.77%) which mostly affects the age group of 0–10 years (72.64%) and 61–70 years (38.6%). Analysis of different factors revealed that age is significantly correlated with the outcome having P = 0.016. Glasgow Coma Scale, saturation of peripheral oxygen, systolic blood pressure at admission are also significantly correlated with the outcome having P < 0.001, P < 0.001, and P < 0.001, respectively. Conclusion: It is evident from the study that the factors which affect the outcome of a TBI are influenced by prehospital care, and thus prehospital management of the TBIs can definitely improve the outcomes.
Isolated orbital roof fracture: Can it be catastrophic?
Authors: Sadashivam Saravanan
Published: January 2022

Orbital encephalocele is a rare catastrophic complication of orbital roof fractures. Early diagnosis of this posttraumatic orbital encephalocele is very crucial because this condition if untreated leads to rapid loss of vision. Whenever displaced orbital roof fracture is identified in a head injury patient, an orbital encephalocele should be suspected. Although magnetic resonance imaging is the investigation of choice, computed tomography of orbit with thin axial and coronal sequences often gives the diagnosis. Frontobasal approach is the most commonly used surgical approach. Supra-transorbital approach is a minimally invasive alternative. Good results with regard to the orbital symptoms can be expected.

Published: January 2022

Introduction: Epidural hematoma (EDH) is a traumatic accumulation of blood between the inner table of the skull and the stripped off dural membrane and predominantly consists of venous blood in infants. The study aims to assess the outcome of pediatric EDH using King's Outcome Scale for Childhood Head Injury (KOSCHI). Materials and Methods: A total of 72 patients' files were reviewed retrospectively with a diagnosis of EDH from January 2012 to December 2014. Predesigned proforma was filled using data from patient records. In addition, KOSCHI was calculated using recent telephone interviews. Results: Among 72 patients, 65.3% were male and 34.7% were female. Overall, road traffic accident was the most common cause (52.8%) followed by fall, assault, and sports injury. The most common symptom was more than two episodes of vomiting which was present in 51.4% of patients followed by loss of consciousness in 37.5%, ENT bleed in 33.3%, headache in 16.7%, and fits in 11.1% of patients. The median follow-up of our patients was 19 (6–40) months. Most of our patients made good recovery with 76.4% of our patients scoring 5b on KOSCHI. Conclusion: EDH is not uncommon among children with head injury. It should be suspected in every child with posttraumatic skull fracture or scalp hematoma. Prompt surgical intervention can give good long-term outcome.

Background: Spinal cord injury (SCI) causes sensory, motor function and consists of a large proportion of patients that referred to trauma centers. Riluzole blocks the sodium channels and has possible supportive effects on the central nervous system. The aim of this study was to investigate the effect of riluzole on sensory and motor improvement and pain level in patients with acute SCI. Materials and Methods: In this clinical trial, sixty patients with acute SCI with A to C Frankel grade selected and randomly divided into two groups (each group included thirty patients). The two groups carefully matched in terms of age, sex, and Frankel class. Case group, in addition to conventional treatment, received riluzole and was evaluated after 6-week, 3-month, and 6-month periods in terms of sensory and motor status and compared with control group. Results: There were sixty patients divided into case and control groups. In the 6-week follow-up period and 3-month follow-up period, there was no significant difference between the two groups based on sensory and motor function (P = 0.053). In 6-month follow-up period, the difference was significant in case group (P = 0.001). Conclusion: The compressions between two groups demonstrated a significant difference in sensory and motor improvement and reduce pain level in patients with SCI.

Authors: Yarandi K , Jelodar Sina , Khalatbari Mahmoud , Rasras Saleh , Ilkhchi Reza , Amirjamshidi Abbas
Published: January 2022

Background and Objectives: Stabbing the head is a rare event. It may occur following an assault or self-inflicted injury. We intend to report our experience with four such cases and review narratively the relevant literature. A treatment algorithm will be delivered. Materials and Methods: We have reviewed four of our cases; three were stabbed to the orbit and one to the head. Results: Enucleation was performed in one case. Vision could be preserved in the other two and brain abscess developed in the other cases due to a retained piece of knife. We made a comparison between our cases and those limited reports in the literature to reach an algorithm. Conclusion: The temporal region and the orbit are the targets mostly attacked in the craniofacial stabs. Since knives have a sharp and thin edge, they may break when penetrating the skull. The damage to the brain tissue and the retained piece of knife may be missed easily by overlooking the small injury to the scalp. The suggested algorithm would be a contrast-enhanced computed tomography scan of the skull and brain and a kind of brain vascular study are necessary, considering the location of the knife in the skull and brain passing the area with crowded vasculature. The best treatment protocol is surgery accompanied by antibiotic therapy.

Introduction: The basilar artery (BA) is formed by the fusion of right and left vertebral arteries and divides to form right and left posterior cerebral arteries. This study was done to provide a baseline database regarding length, mid-length diameter, level of origin, and level of termination of BA.Materials and Methods: Thirty-eight formalin-fixed brains were obtained from cadavers dissected for undergraduate studies. The external length and the average external diameter of BA were measured by a digital Vernier caliper. Variation in origin and termination of BA was noted using magnifying glass. Results: The length and diameter of the BA were 25.58 ± 3.57 mm and 3.05 ± 0.41 mm, respectively. The origin and termination of BA was normal in most cases. In two cases, the origin was above the pontomedullary junction, and in one case, it was below. In two cases, the termination was above the pontomesencephalic junction, and in one case, it was below. Conclusion: There was no gender predisposition in length and diameter of the basilar artery. The baseline data established in this study regarding length, diameter, level of origin and level of termination of basilar artery will help neurosurgeons and interventional radiologists to diagnose as well as plan and execute various vascular procedures such as shunting for the treatment of aneurysms and stenosis in the blood vessels of the posterior cranial fossa.

Published: January 2022

Melanotic schwannomas (MS) are rare variants of schwannomas the occurrence of which is described in case reports only. They usually arise from posterior spinal nerve roots and less commonly from other cells of neural crest origin. Although they are relatively benign tumors in young, aggressive behavior is reported. They occur as isolated tumors or as part of a syndrome named Carney complex. We try to describe the pathology, diagnosis, management, and prognosis of MSs in two different cases: one cervical intramedullary with no recurrence on 5-year follow-up and the other one extramedullary in lumbar region with early recurrence and aggressive course. A brief review of literature is done.

Authors: Eghbal Keyvan , Abdollahpour Hamid , Ghaffarpasand Fariborz
Published: January 2022

Cervical spine chance fracture (flexion-distraction) is a rare type of fracture, and the surgical management remains a dilemma to the neurosurgeons as there is a paucity of evidence accordingly. We herein report a traumatic chance fracture of C7 fractures and its surgical management. A 33-year-old male was transferred to our center after being hit as pedestrian and was diagnosed to have a chance fracture of C7 and bilateral C7 root injury. He underwent open reduction of the deformity by posterior-only fixation of C5 and C6 with a lateral mass screw and T1 and T2 with pedicular screws. The neurological examination improved postoperatively, and the patients were neurologically intact after 6 months of treatment. Traumatic cervical spine chance fracture is extremely rare and can be managed surgically through posterior fixation and open reduction of the deformity. The best choice of treatment is limited by the paucity of the evidence and should be individualized.

Authors: Sandra S. Canty , Anusha R. , Madankumar P. D.
Published: January 2022

The goal of this systematic review was to describe the use of augmented reality and virtual reality in cigarette smoking cessation and the adherence to smoking cessation among smokers. We searched several databases to identify suitable studies published between September 2011 and September 2021 for inclusion in this review. Suitable MeSH terms were used to devise a precise search strategy using PubMed, Google Scholar, Cochrane Library, and Turning Research into Practice database. The search yielded 304 articles, of which 5 were selected and 4 were considered for quality assessment. All four studies suggested that when the intervention was given through virtual reality, the adherence to smoking cessation was apparently high. Promoting cigarette cessation through conventional techniques could take a longer time for achieving commitment among those who wished to quit, while virtual reality created an interest to quit smoking. Arranging for augmented and virtual reality experiences for smokers through mobile applications and virtual reality headsets in the future could help improve smoking cessation and adherence compared to conventional pamphlets for health education.

Background:

Neonatal bronchopulmonary dysplasia (BPD) is a chronic neonatal respiratory disease that is precipitated by prolonged oxygenation and mechanical ventilation (MV), leading to respiratory distress (RD).

Aim of Study:

The aim of the study is to assess the role of Vitamin D as adjuvant treatment in the prevention and management of BPD in neonates.

Patients and Methods:

Prospective randomized controlled trial with identification number TCTR20210622001 on 100 premature neonates who had RD and were put on MV. The examined neonates were classified into 2 groups: Group 1, which received Vitamin D (Vit D), and Group 2, which had placebo. Urinary β2-microglobulin (B2M) in addition to plasma Krebs von den Lungen-6 (KL-6) levels were measured on the 1st and the 14th day of hospitalization.

Results:

There was a decrease in urinary B2M and plasma KL-6 levels in Group 1, if compared with Group 2 neonates (P < 0.05). There was a decrease in hospitalization in Group 1 neonates (P < 0.05). Group 1 neonates showed a decrease of the developed BPD cases (P < 0.05).

Conclusion:

Vit D supplementation may help in the prevention of BPD in neonates, but further studies with larger number of neonates should be done.

Recommendation:

Objective:

We aimed to measure the joint angles of major joints in newborn babies to explore their association with gestational age (GA).

Materials and Methods:

This observational study was conducted to evaluate joint angles in healthy newborn infants, born between 28 and 41 completed weeks of gestation. Healthy and hemodynamically stable babies were selected by purposive sampling up to the 2nd day of life. Six major joints of upper and lower limbs (shoulder, elbow, wrist, hip, knee, and ankle) were assessed on either side. The joint angles and range of motion (ROM) achieved through predefined passive movements were measured by a single observer using a manual acrylic goniometer. The positioning of the joints during measurement was standardized.

Results:

A total of 433 newborn babies, belonging to different GA, were evaluated. The joint angles and ROM did not show any significant differences between right and left sides and between male and female babies. The ROM of flexion-extension and adduction-abduction movement at shoulder, angle of palmer-flexion at wrist, and angle of dorsiflexion at ankle, were observed to correlate strongly with GA (correlation coefficient r of –0.75, –0.74, –0.73, and –0.73, respectively). The relationships were inverse. A mathematical model based upon multiple regression analysis is proposed to predict GA from these four measurements.

Conclusions:

Structured clinical assessment of major joint angles in newborn babies has the potential to provide relatively precise estimation of GA, which may be used to add accuracy to modified New Ballard Score.

Published: January 2022

Neonatal hyperglycemia is a common metabolic disorder seen in very low birth weight (VLBW) and critically ill newborns. Hyperglycemia is a recognized cause for mortality and morbidity in the neonatal period. Incidence in preterm infants is around 45%–80%. The mechanism of increased risk of hyperglycemia in preterm infants is not well understood, but different possible mechanisms have been reported. Plasma glucose values more than 180–200 mg/dl (10–11.1 mmol) are of concern as this can lead to complications. Hyperglycemia was found to predispose to severe intraventricular hemorrhage, retinopathy of prematurity, necrotizing enterocolitis, and increased mortality. It is important to recognize and manage this condition early to avoid serious complications. Multiple etiologies with different management strategies are mentioned in the literature. Here, we discuss a complete understanding on practical management of hyperglycemia and we propose a simplified practical approach for the diagnosis and management of neonatal hyperglycemia.

VIPoma is an extremely rare neuroendocrine tumour. Majority of the lesions occur in the pancreas. There is usually a long and recurrent history of secretory diarrhoea. Current diagnostic methods help in diagnosing a VIPoma once it is suspected. We herein report a case of VIPoma which had the delay in diagnosis and presented at an extremely unusual location (pyloroduodenal) who underwent laparoscopic resection for the same.
Amlodipine overdose complicated by non-cardiogenic pulmonary edema and diffuse alveolar hemorrhage
Authors: Bringgold Will R , Long Micah T
Published: January 2022

A young adult female presented with hypotension and depressed mental status after intentional overdose of Amlodipine. After intubation and institution of lung-protective mechanical ventilation, initial management focused on maintenance of a mean arterial blood pressure over 65 mmHg and included fluid resuscitation (eight liters of crystalloid), Insulin and dextrose, intravenous calcium and, finally, vasopressor support. Her course was complicated by hypoxia due to non-cardiogenic pulmonary edema requiring diuresis. She was extubated soon thereafter but developed severe hypoxia within 72 hours requiring re-intubation. A subsequent bronchoscopy demonstrated diffuse alveolar hemorrhage (DAH). This is the first report of DAH complicating amlodipine overdose.
The efficacy of sphenopalatine ganglion block for the treatment of postdural puncture headache among obstetric population

Published: January 2022

Background:

Postdural puncture headache (PDPH) is a common complication among parturients who had undergone obstetric neuraxial block. Epidural blood patch is the current gold standard treatment for PDPH, although it is an invasive procedure. We conducted this systematic review to assess the efficacy of sphenopalatine ganglion block (SPGB) as a noninvasive treatment of PDPH.

Methods:

Relevant reports were searched from Google Scholar, PubMed, Science Direct, and Scopus from the inception of the databases to November 30, 2020. A total of 10 reports found to be related to SPGB for the treatment of PDPH in the obstetric population were enrolled. Significant relief of headache with no further intervention and initial relief of headache that requires further interventions were considered as the primary outcomes. The secondary outcome was the complications after SPGB.

Results:

A total of 68 patients were identified. We found that 41 of 68 patients (60.3%) had effective management with significant relief of headache with no further interventions needed. Moreover, a total of 27 of 68 patients (39.7%) had initially effective management that needed further interventions. The use of 2% lidocaine was found to be the most effective among all used local anesthetics with 85.7% effective management. Furthermore, parturients who developed PDPH after spinal anesthesia responded to SPGB better than other obstetric neuraxial techniques.

Conclusions:

This systematic review showed that SPGB is a promising treatment modality for the management of PDPH with no reported complications. Before recommending this technique for treating PDPH, we are calling for randomized clinical trials to prove its efficacy.

Abstract

This study aims to improve the nutritional quality of venison floss by modifying the the technology process of floss making with adding red fruit oil (Pandanus conoideus L) and kebar grass extract (Biophytum petersianum) as a source of natural antioxidants. The results showed that the nutritional value of floss was influenced by the use of these herbal.  Supplementation of antioxidant  is to potentially extend the shelf-life of floss as indicated in decreasing the value of water activity (Aw) and thiobarburic acid (TBA).  The Aw value decreased from 0.756 to 0.701, and TBA decreased from 0.139 to 0.055 mg/kg.  The protein of floss increased from 33.20 to 35.60%.  The result also showed that the content of antioxidant increased which is indicated by the increasing of beta-carotene content from 0.0087 mg /100 gram to 0.81 mg/100 gram. Results also showed that the use of red fruit oil extract and kebar grass extract decreased the content of saturated fatty acids, meanwhile in unsaturated fatty acids it increased arachidonic fatty acids.

La Vejez y el derecho de la seguridad social
Authors: VINUEZA FLORES Mónica
Published: January 2022

Para el derecho de la seguridad social la vejez es una noción medular, pues a partir de ella los sistemas de seguridad social organizan una cierta protección de los individuos a través, especialmente, de los seguros de vejez destinados únicamente a las personas adultas mayores o de la tercera edad. Sin embargo, ¿quiénes son estas personas a la luz de los seguros de vejez? ¿cuál es esa vejez que considera el derecho de la seguridad social? ¿la vejez social? ¿la vejez biológica? ¿la vejez psicológica? ¿la vejez profesional? Sin duda alguna las respuestas a estas interrogantes se encuentran en las convenciones sociales y en la biología.
Entre placer y salud: Alimentación y distinción en las recetas culinarias del Kitab al ṭabīẖ
Authors: JAWHARA PIÑER Hélène
Published: January 2022

Este artículo se centrará en el lugar que ocupa la dietética en el primer libro de cocina conocido de la Península Ibérica: el Kitāb al-ṭabīẖ [El libro de cocina]. ¿El placer de comer era compatible con una alimentación saludable? ¿Existía el deseo o la necesidad de diferenciarlos? Los índices esparcidos por el libro de cocina nos orientan hacia una dirección correcta. De hecho, el autor anónimo – que cita a Galeno e Hipócrates – inscribe el Kitāb al-ṭabīẖ en la tradición dietética griega pasada. ¿El coste o la escasez de ciertos alimentos permitirían una distinción social? ¿El modo de preparación de las recetas marcaría una preferencia para una alimentación saludable sobre una comida placentera? Estas diversas preguntas reflejan la complejidad de establecer una clara distinción social, dietética y económica en el Kitāb al-ṭabīẖ. Lo que parece claro, sin embargo, es que el conocimiento del autor en medicina, dieta y cocina es innegable.
