Published: February 2020

Background: Pneumocephalus is defined as presence of intracranial gas. It can be at any site in the cranium; isolated or at different sites simultaneously. Quantity of gas along with extent of mass effect caused by it & severity of clinical symptoms will determine the modality of treatment; i.e. conservative or surgical. Among many etiologies trauma is one, which is one of the most common cause as in our case. Multiple foci of gas scattered within the subarachnoid space, especially in the cisterns seen on CT scan of brain has been described as “Air bubble sign”, indicating of subdural tension PNC. Here we have presented our case with review of management of such condition, especially conservative.
Case: A case of 55yrs male with history of road traffic accident was referred from another hospital. CT scan of Brain done in previous center showed diffuse PNC scattered throughout the subarachnoid space. The patient was managed conservatively and successive repeat CT scan showed gradual to complete resorption of gas and simultaneous clinical improvement of the patient.
Conclusion: “Air bubble sign” described as a sign of tension PNC can be managed conservatively in absence of significant clinical symptoms and may not only be associated with subdural tension PNC. The modality of treatment of PNC as well for tension PNC should be tailored according to the patient’s clinical status.

OBJECTIVEExtensive resection of a tumor in the posterior fossa in children is associated with the risk of neurological deficits. The objective of this study was to prospectively evaluate the short-term neurological morbidity in children after medulloblastoma surgery and relate this to the tumor’s growth pattern and to the extent of resection.METHODSIn 160 patients taking part in the HIT-SIOP PNET 4 (Hyperfractionated Versus Conventionally Fractionated Radiotherapy in Standard Risk Medulloblastoma) trial, neurosurgeons prospectively responded to questions concerning the growth pattern of the tumor they had resected. The extent of resection (gross, near, or subtotal) was evaluated using MRI. The patients’ neurological status before resection and around 30 days after resection was recorded.RESULTSInvasive tumor growth, defined as local invasion in the brain or meninges, cranial nerve, or major vessel, was reported in 58% of the patients. After surgery almost 70% of all patients were affected by one or several neurological impairments (e.g., impaired vision, impaired extraocular movements, and ataxia). However, this figure was very similar to the preoperative findings. Invasive tumor growth implied a significantly higher number of impairments after surgery (p = 0.03) and greater deterioration regarding extraocular movements (p = 0.012), facial weakness (p = 0.048), and ataxia in the arms (p = 0.014) and trunk (p = 0.025) compared with noninvasive tumor growth. This deterioration was not dependent on the extent of resection performed. Progression-free survival (PFS) at 5 years was 80% ± 4% and 76% ± 5% for patients with invasive and noninvasive tumor growth, respectively, with no difference in the 5-year PFS for extent of resection.CONCLUSIONSPreoperative neurological impairments and invasive tumor growth were strong predictors of deterioration in short-term neurological outcome after medulloblastoma neurosurgery, whereas the extent of resection was not. Neither tumor invasiveness nor extent of resection influenced PFS. These findings support the continuation of maximal safe resection in medulloblastoma surgery where functional risks are not taken in areas with tumor invasion.

OBJECTIVERecurrent tethered cord syndrome (TCS), believed to result from tension on the distal portion of the spinal cord, causes a constellation of neurological symptoms. Detethering surgery has been the traditional treatment for TCS. However, in cases of recurrent TCS, there is a risk of new neurological deficits developing, and subsequent retethering is difficult to prevent. Spinal column shortening has been proposed as an alternative technique to reduce the tension on the spinal cord without incurring the morbidity of revision surgery on the spinal cord. The authors compared the perioperative outcomes and morbidity of patients who were treated with one or the other procedure.METHODSThe medical records of 16 adult patients with recurrent TCS who were treated between 2005 and 2018 were reviewed. Eight patients underwent spinal column shortening, and 8 patients underwent revision detethering surgery. Patient demographics, clinical outcomes, and perioperative factors were analyzed. The authors include a video to illustrate their technique of spinal column shortening.RESULTSWithin the spinal column shortening group, no patients experienced any complications, and all 8 patients either improved or stabilized with regard to lower-extremity and bowel and bladder function. Within the revision detethering group, 2 patients had worsening of lower-extremity strength, 3 patients had worsening of bowel and bladder function, and 1 patient had improvement in bladder function. Also, 3 patients had wound-related complications. The median estimated blood loss was 731 ml in the shortening group and 163 ml in the revision detethering group. The median operative time was 358 minutes in the shortening group and 226 minutes in the revision detethering group.CONCLUSIONSClinical outcomes were comparable between the groups, but none of the spinal column shortening patients experienced worsening, whereas 3 of the revision detethering patients did and also had wound-related complications. Although the operative times and blood loss were higher in the spinal column shortening group, this procedure may be an alternative to revision detethering in extremely scarred or complex wound revision cases.

Performance Analysis of the Supercritical Carbon Dioxide Re-compression Brayton Cycle
Authors: Salim Mohammad Saad , Saeed Muhammad , Kim Man-Hoe 
Published: February 2020

This paper presents performance analysis results on supercritical carbon dioxide ( s C O 2 ) re-compression Brayton cycle. Monthly exergy destruction analysis was conducted to find the effects of different ambient and water temperatures on the performance of the system. The results reveal that the gas cooler is the major source of exergy destruction in the system. The total exergy destruction has the lowest value of 390.1 kW when the compressor inlet temperature is near the critical point (at 35 °C) and the compressor outlet pressure is comparatively low ( 24 MPa ). The optimum mass fraction (x) and efficiency of the cycle increase with turbine inlet temperature. The highest efficiency of 49% is obtained at the mass fraction of x = 0.74 and turbine inlet temperature of 700 °C. For predicting the cost of the system, the total heat transfer area coefficient ( U A T o t a l ) and size parameter (SP) are used. The U A T o t a l value has the maximum for the split mass fraction of 0.74 corresponding to the maximum value of thermal efficiency. The SP value for the turbine is 0.212 dm at the turbine inlet temperature of 700 °C and it increases with increasing turbine inlet temperature. However the SP values of the main compressor and re-compressor increase with increasing compressor inlet temperature.

Abstract
In this Letter, we present the application of a couple of novel deep learning models to the forecast of major solar X-ray flare flux profiles. These models are based on a sequence-to-sequence framework using long short-term memory cell and an attention mechanism. For this, we use Geostationary Operational Environmental Satellite 10 X-ray flux data from 1998 August to 2006 April. Seven hundred sixty events are used for training and 85 for testing. The models forecast 30 minutes of X-ray flux profiles during the rise phase of the solar flare with a minute time cadence. We evaluate the models using the 10-fold cross-validation and rms error (RMSE) based on flux profiles and RMSE based on its peak flux. For comparison we consider two simple deep learning models and four conventional regression models. Major results of this study are as follows. First, we successfully apply our deep learning models to the forecast of solar flare X-ray flux profiles, without any preprocessing to extract features from data. Second, our proposed models outperform the other models. Third, our models achieve better performance for forecasting X-ray flux profiles with low-peak fluxes than those with high-peak fluxes. Fourth, our models successfully predict flare duration with high correlations for both all cases and cases at peak times. Our study indicates that our deep learning models can be useful for forecasting time-series data in astronomy and space weather, even for impulsive events such as major flares.

Background Neuraminidase (NA) inhibitors (NAIs), including oseltamivir and zanamivir, play an important therapeutic role against influenza infections in immunocompromised patients. In such settings, however, NAI therapy may lead to the emergence of resistance involving mutations within the influenza surface genes. The aim of this study was to investigate the evolution of NA and haemagglutinin (HA) genes of influenza A(H1N1) pdm09 virus in an immunocompromised patient receiving oseltamivir then zanamivir therapies. Methods Nasopharyngeal swab (NPS) samples were collected between 27 January 2018 and 11 April 2018 from a haematopoietic stem cell transplant recipient. These include 10 samples collected either pre-therapy, during oseltamivir and zanamivir treatment as well as after therapy. The A(H1N1)pdm09 HA/NA genes were sequenced. The H275Y NA substitution was quantified by droplet digital RT-PCR assay. A(H1N1)pdm09 recombinant viruses containing HA mutations were tested by HA elution experiments to investigate in vitro binding properties. Results Oseltamivir rapidly induced the H275Y NA mutation which constituted 98.33% of the viral population after 15 days of oseltamivir treatment. The related HA gene contained S135A and P183S substitutions within the receptor-binding site. After a switch to zanamivir, 275H/Y and 119E/G/D mixed populations were detected. In the last samples, the double H275Y-E119G NA variant dominated with S135A and P183S HA substitutions. Conclusions This report confirms that oseltamivir can rapidly induce the emergence of the H275Y substitution in A(H1N1)pdm09 viruses and subsequent switch to zanamivir can lead to additional substitutions at codon E119 resulting in multi-drug resistance. Such data additionally suggest a potential compensatory role for HA substitutions near the receptor binding site.

Published: February 2020

PURPOSE:
To determine 2-year efficacy of accelerated corneal cross-linking (CXL) in keratoconus treatment using standard riboflavin-dextran or hypotonic riboflavin solutions.

METHODS:

Patients undergoing accelerated CXL (epitheliumoff 10 minutes, 9 mW/cm
2
protocol) with standard riboflavin solution (48 eyes of 48 patients) or hypotonic riboflavin solution (43 eyes of 43 patients) were included and followed up for 2 years. Thinnest corneal thickness (TCT), maximum keratometry, and visual acuity were measured and changes from baseline to postoperative 6, 12, and 24 months were compared between the two groups.

RESULTS:

The preoperative mean TCT with intact epithelium was 472.0 ± 23.9 and 427.5 ± 22.3 µm in the standard riboflavin and hypotonic riboflavin groups, respectively (
P
< .001). The decreases in the mean TCT values from baseline to postoperative 6 months were similar between the standard riboflavin (from 472 to 436 µm) and hypotonic riboflavin (from 427 to 394 µm) groups. This suggested that the hypotonic riboflavin solution was comparable with the standard riboflavin solution in preserving corneal thickness in keratoconus. There were no significant differences between the study groups regarding the postoperative changes in maximum keratometry or visual acuity.

CONCLUSIONS:
The efficacy of accelerated CXL with hypotonic riboflavin solution was comparable to that with the standard riboflavin solution in reducing keratoconus progression in a 2-year follow-up period.

Evaluation of ecotoxicity of contaminated water for validation of phytoremediation time
Authors: Fernandes Katiúcia Dias , Roque Amanda De Campos , Fonseca Ana Lúcia 
Published: February 2020

Phytoremediation has been used as an alternative for removal of heavy metals in aquatic environments, but plant residence time and toxicity reduction need to be studied. Ecotoxicological bioassays and root anatomic studies were conducted in order to validate the phytoremediation of Echinochloa crus-galli L. at three different ages. The experiment was conducted using E. crus-galli seeds with processing factorial experimental design (2x3) and four replicates. Cadmium presence and absence (0.8 and 0 mg L-1) at three times (20, 30, and 45 days after germination). Cd levels were quantified by flame atomic absorption spectroscopy on both aerial parts and roots. A bioassay was performed testing both acute and chronic effects using microcrustacean Daphnia similis with the purpose of evaluating phytoremediation efficiency. Regardless of biomass, E. crus-galli L. can be used for 16 to 19 days for 45 days after germination (DAG), tolerating the phytotoxicity of this metal. The residual solution after phytoremediation had chronic effect on D. similis, indicating that the time taken was not sufficient to reduce the toxicity of the solution. Thus, ecotoxicological essays are important tools in evaluating the efficiency of this type of process. While E. crus-galli L. is a valuable tool in Cd phytoremediation programs, exposure time must be higher than 19 days to reduce concentrations of this metal in the water to conform to the CONAMA 357/2005 e 430/2011 standards.

The study was carried out to assess the information and communication technology usage by maize farmers in Afijio Local Government Area of Oyo State. The study was necessitated by persistent poor communication of new technologies from research institutes which has hampered the productivity and livelihood of farmers. The parameters assessed include socio-economic characteristics of the respondents, ICT devices used, extent of radio usage, extent of mobile phone usage, effect of radio on maize farming, effect of mobile phone on maize farming, and constraints to effective use of ICT among respondents, respectively. A multistage sampling procedure was used for sample selection with 30% random selection of 10 wards which were Aawe, Imini, and Ilora with 8 villages selected randomly, and from each of these 8 selected villages, 10 respondents were selected systematically to give rise to a total of 80 respondents as sample size. A well-structured questionnaire was used for data collection while frequencies, percentages, chi-square and pearson product moment correlation were used for data analysis. The results showed that 60.0% of the respondents were male while 40.0% were female. The findings revealed that the use of radio, television and mobile phone has increased the income and livelihood of the maize farmers due to new methods learnt from agricultural programmes, also maize farmers have been exposed to latest technology on maize production through watching of documentaries and communicating with other maize farmers and customers. The study also showed the problems faced by the respondents were irregular power supply, high cost of ICT devices, and inadequate knowledge on technical know-how. It was therefore recommended that Maize farmers should be encouraged to access and utilize ICTs by supporting, them financially and materially by the governments and private sectors/donor agencies. Government should improve on electricity supply to the rural areas which will enable the farmers to utilize the ICT devices.Keywords: Information Communication Technologies, Usage, Maize farmers

Importance >Aesthetic rhinoplasty is the fifth surgical procedure most performed worldwide by plastic surgeons. With the growing demand for rhinoplasty, there is an unmet need for research into the profile of patients who seek aesthetic nasal surgery in an attempt to improve not only cosmetic dissatisfactions, but also the manifestations of other, possibly interrelated disorders, especially sleep disturbances.
Objective To evaluate the sleep quality and the risk of Obstructive Sleep Apnea in patients referred for aesthetic rhinoplasty, as well as the association of these conditions with nasal symptoms. Design: Cross-sectional study performed at the period of June/2016 to August/2017. Setting: Department of Otolaryngology and Head and Neck Surgery - Universidade Federal de São Paulo. Participants: Patients of both sexes, aged 18 to 65 years, who were referred for aesthetic rhinoplasty. We evaluated 46 patients, two of whom were excluded because they were outside the inclusion age criteria. Main Outcome(s) and Measure(s): Anterior rhinoscopy and the following validated surveys were used. Pittsburgh Sleep Quality Index; Epworth Sleepiness Scale; Nasal Obstruction Symptom Evaluation scale; Berlin Questionnaire. The visual analog scale for snoring was also used.
Results Of the 44 participants, 18 (41%) were males and 26 (59%) were females. 82% had poor sleep quality. 46% presented excessive daytime sleepiness. There was a high risk for Obstructive Sleep Apnea in 27%. Regarding to nasal symptoms, the mean score in the Nasal Obstructive Symptoms Evaluation was 66.25±25.38. When comparing the groups with good and poor sleep quality, we observed a higher risk for Obstructive Sleep Apnea (p=0.05) in patients with poor sleep quality. Patients at high risk for Obstructive Sleep Apnea had higher scores on the Nasal Obstructive Symptoms Evaluation (p=0.001) and on the analogue snoring scale (p<0.001) compared to patients at low risk.
Conclusions We observed a high occurrence of poor sleep quality in participants. All participants who were at high risk for obstructive sleep apnea were also classified as having poor sleep quality. An association was also observed between the presence of high risk for obstructive sleep apnea and presence of nasal symptoms.
