Abstract: The assessment of carbon stocks is one of the key measurements to support climate change mitigation policies. The research applied Landsat 8 satellite imagery combined with field-measurements using four machine learning methods (random forest - RF, artificial neural networks - NNET, support vector machines – SVM, and linear regression - LM) to estimate aboveground carbon in evergreen broadleaf forest in Binh Phuoc province. The field sample plots were randomly divided into training (96 plots) and testing (24 plots) data. The results showed that RF yielded the greatest precision with an R2 value above 0,9 and RMSE below 6 ton/ha on the training data, with an R2 value of 0,41 and RMSE of 11,04 ton/ha on the testing data. The estimate of forest carbon stock increased distinctly from the mean value of 59,80 ton/ha in the very poor forest to 87,78 ton/ha in the rich forest. The results found in the present study demonstrated that Landsat 8 imagery in conjunction with RF has the appropriate to estimate aboveground carbon stock in evergreen broadleaf forest-leaved in Binh Phuoc province.

Background:
Cauda equina syndrome (CES) is typically caused by a compressive etiology from a herniated disk, tumor, or fracture of the spine compressing the thecal sac. Here, we report a CES mimic – acute aortic occlusion (AAO), a rare disease that is associated with high morbidity and mortality. AAO can compromise spinal cord blood supply and leads to spinal cord ischemia.

Case Description:
Our patient presented with an acute onset of bilateral lower extremity pain and weakness with bowel/bladder incontinence, a constellation of symptoms concerning for CES. However, on initial imaging, there was no compression of his thecal sac to explain his symptomology. Further, investigation revealed an AAO. The patient underwent an emergent aortic thrombectomy with resolution of symptoms.

Conclusion:
AAO can mimic CES and should be considered in one’s differential diagnosis when imaging is negative for any spinal compressive etiologies.

В работе показаны возможности применения композитных структур ZnO-Fe в качестве газочувствительных слоев для детектирования паров органических растворителей на примере изопропилового спирта. Композитные структуры получены на основе наностержней оксида цинка, синтезированных гидротермальным методом, за счет изменения их состава при выдержке в растворе сульфата железа. Исследование химического состава поверхности проводили с помощью рентгеновской фотоэлектронной спектроскопии. Показано, что при использовании раствора сульфата железа с концентрацией 0,025 моль/л на поверхности наблюдаются атомы железа и цинка. Повышение концентрации раствора до 0,05 моль/л приводит к осаждению частиц оксида железа на поверхность слоя наностержней. Исследование газочувствительных характеристик проводили при температуре 250°С при воздействии паров изопропилового спирта в диапазоне концентраций от 200 до 1000 млн. Установлено, что величина отклика композитных структур ZnO-Fe (0,025) превышает соответствующее значение для наностержней оксида цинка, что может быть обусловлено большим содержанием кислородных вакансий в композитном образце.
The paper shows the possibilities of using ZnO-Fe composite structures as gas-sensitive layers for detecting organic solvent vapors exemplifying on isopropyl alcohol. Composite structures were formed based on zinc oxide nanorods synthesized by the hydrothermal method, due to changes in their composition in a ferrous sulfate solution. The chemical composition of the surface was studied using X-ray photoelectron spectroscopy. It is shown that when using a ferrous sulfate solution with a concentration of 0,025 mol/l, iron and zinc atoms are observed on the surface. An increase in the concentration of the solution to 0,05 mol/l leads to the deposition of iron oxide particles on the surface of the nanorods. The study of some gas-sensitive characteristics was carried out at 250°C when exposed to isopropyl alcohol vapors in the concentration range from 200 to 1000 ppm. It was found that the response value of composite structures ZnO-Fe (0,025) exceeds the corresponding value for the zinc oxide nanorods, that may be due to the high content of oxygen vacancies in the composite sample.

The Possessive Resultative Passive in Ukrainian
Authors: Popovic Ljudmila 
Published: December 2022

In Ukrainian, the possessive resultative passive is represented by subject constructions that are comprised of the verb maty (to have) and passive participle (e.g. maju zapysani pisni ‘I have written songs’, mala naskladano troxy hroshey ‘she had saved some money’ etc.). These constructions, which are a grammatical norm in West Slavic, Macedonian, and Bulgarian, are an innovation in Ukrainian that has not been investigated enough. In this paper three models of the possessive resultative passive construction are differentiated. The degrees of their presence in Ukrainian are different. My linguistic data shows that some varieties of the possessive resultative passive construction are productive in the colloquial language, as well as in the electronic and technical discourses in Ukrainian.

Published: December 2022

Pulmonary tuberculosis is an infectious disease caused by Mycobacterium tuberculosis (MTB). Regarding this, Indonesia is ranked second globally in terms of tuberculosis prevalence. TB cases in Sumenep Regency are increasing every year. The high incidence of TB in Sumenep mostly is caused by the patients' lack of adherence to taking medication. The level of compliance in taking drugs can be influenced by several factors including age, educational level, and gender. This study aimed to ascertain the association between medication adherence and recovery in patients with pulmonary tuberculosis at the Gapura Public Health Center Sumenep. This study employed an analytical observational design with a cross-sectional approach, utilizing secondary data from medical records and TB.01 treatment cards. The population in this study consisted of 40 individuals. Total sampling is used to choose samples. The study's findings revealed that most patients 62.5% were male, 37.5% were between the ages of 26-45, 15% were from Gapura Barat, 35% had an elementary school education, and 55% were farmers. As many as 90% of patients adhere to treatment and 87.5% recover. Additionally, statistical tests yielded a p-value of <0.001. The study concludes a correlation between medication adherence and recovery of patients with pulmonary tuberculosis at the Gapura Public Health Center Sumenep. It is advised that health personnel maintain as many programs as possible, including counseling, home visits, and remote monitoring via telecommunications.

Corona virus or servere acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a disease that results in the occurrence of mild to moderate respiratory tract infections. Positive cases of Covid-19 in Indonesia were first detected on March 2, 2020 and continue until 2022. The additional number of deaths caused by COVID-19 has also increased. Therefore, the author is interested in making a predictive model of the cumulative number of COVID-19 patients who died in Indonesia. Therefore, in this study is how to predict the number of patients who die from COVID-19 in Indonesia by creating an appropriate accuracy model to help estimate the number of deaths associated with COVID-19 in Indonesia and assist the government in dealing with cases of new variants of COVID-19. In this study, the authors used the Decision Tree model using entropy criteria as well as Information Gain and Random Forest which resulted in accuracy rates of 91.83% (Decission Tree) and 73.80% (Random Forest). The results, explain that the model used is good. The more the R-squared error value is close to 1, the better the model used will be

OBJECTIVE
Posterior cervical fusion is a common surgical treatment for patients with myeloradiculopathy or regional deformity. Several studies have found increased stresses at the cervicothoracic junction (CTJ) and significantly higher revision surgery rates in multilevel cervical constructs that terminate at C7. The purpose of this study was to investigate the biomechanical effects of selecting C7 versus T1 versus T2 as the lowest instrumented vertebra (LIV) in multisegmental posterior cervicothoracic fusion procedures.

METHODS
Seven fresh-frozen cadaveric cervicothoracic spines (C2–L1) with ribs intact were tested. After analysis of the intact specimens, posterior rods and lateral mass screws were sequentially added to create the following constructs: C3–7 fixation, C3–T1 fixation, and C3–T2 fixation. In vitro flexibility tests were performed to determine the range of motion (ROM) of each group in flexion-extension (FE), lateral bending (LB), and axial rotation (AR), and to measure intradiscal pressure of the distal adjacent level (DAL).

RESULTS
In FE, selecting C7 as the LIV instead of crossing the CTJ resulted in the greatest increase in ROM (2.54°) and pressure (29.57 pound-force per square inch [psi]) at the DAL in the construct relative to the intact specimen. In LB, selecting T1 as the LIV resulted in the greatest increase in motion (0.78°) and the lowest increase in pressure (3.51 psi) at the DAL relative to intact spines. In AR, selecting T2 as the LIV resulted in the greatest increase in motion (0.20°) at the DAL, while selecting T1 as the LIV resulted in the greatest increase in pressure (8.28 psi) in constructs relative to intact specimens. Although these trends did not reach statistical significance, the observed differences were most apparent in FE, where crossing the CTJ resulted in less motion and lower intradiscal pressures at the DAL.

CONCLUSIONS
The present biomechanical cadaveric study demonstrated that a cervical posterior fixation construct with its LIV crossing the CTJ produces less stress in its distal adjacent discs compared with constructs with C7 as the LIV. Future clinical testing is necessary to determine the impact of this finding on patient outcomes.

OBJECTIVE
In sub-Saharan Africa, neural tube defects (NTDs) are the second most common birth defect, occurring eight times more frequently than in the US. The objective of this study was to assess baseline Zambian caregiver understanding of folate and NTDs and the effectiveness of an NTD prevention educational program.

METHODS
This prospective survey-based study included Zambian caregivers of children born with NTDs who completed pre- and post-educational program surveys between January 2020 and January 2021. The verbal survey was administered in English or local Zambian dialects. The 1-hour educational program administered by local Zambian research nurses sought to facilitate understanding of the direct relationship between prenatal folate supplementation and NTDs.

RESULTS
Sixty-one eligible caregivers with a median age of 20 (IQR 24–29) years completed the survey. Participants were predominantly from regions outside of Lusaka Province (68%, 41/60) rather than the capital city, Lusaka (32%, 19/60). Most had received prenatal care (91%, 57/61), and 80% (47/59) reported folate use in pregnancy. Of the mothers who took folate during pregnancy, 24% (11/45) reported use within the first 4 weeks after conception, while 76% (34/45) started thereafter. Myelomeningocele was the most common NTD (74%, 32/43), followed by meningocele (14%, 6/43). Prior to the educational program, 52% (29/56) of caregivers reported that NTDs were caused by a vitamin deficiency, which improved to 98% (55/56) after the program (p < 0.001). Furthermore, only 54% (33/61) of caregivers believed that folate should be taken before conception on the baseline survey evaluation, which improved to 95% (58/61, p < 0.001) after the program. All survey participants (58/58) found the educational session helpful.

CONCLUSIONS
This study found that a high proportion of Zambian caregivers had received prenatal care and even had taken folate during pregnancy, but none had taken it prior to pregnancy. An educational program effectively improved understanding about the role and timing of perinatal folate administration in NTD prevention. This result also emphasizes the need for folate fortification and folate education for not only mothers but also primary care providers.
Effect of clevidipine on intracranial pressure in pediatric neurosurgical patients: a single-center retrospective review
Authors: Vadasz Elizabeth , Moss Jeffrey , Chang Nathan , Casazza May , Rasmussen Lindsey 
Published: December 2022

OBJECTIVE
Hemodynamic management in pediatric neurosurgical patients is essential for maintaining cerebral perfusion pressure (CPP), avoiding hemorrhage, and preventing secondary neurological injury. Antihypertensive infusions approved for pediatrics are not widely studied in the pediatric neurosurgical population and may have adverse effects on intracranial pressure (ICP), contributing to reduced CPP. Clevidipine is an ultra–rapid-acting intravenous antihypertensive agent used for hemodynamic control in adult surgical patients. In pediatric patients, clevidipine is safe and effective in controlling blood pressure in the perioperative period, although studies evaluating its effect on ICP in neurosurgical patients are lacking. The objective of this research was to evaluate the effect of clevidipine on ICP in pediatric neurosurgical patients.

METHODS
This single-center retrospective study involved patients admitted to the pediatric ICU between January 1, 2017, and December 31, 2020. Patients eligible for inclusion had ICP monitoring devices and received clevidipine infusion for a minimum of 6 hours postoperatively, with at least one ICP measurement pre- and postinfusion. Excluded patients had an elevated preinfusion ICP > 20 mm Hg. The primary outcome was the average change in ICP from preinfusion baseline to hours 6 to < 12, 12 to < 24, and 24 to < 48 of clevidipine infusion. Secondary outcomes included frequency of ICP measurements > 20 mm Hg, CPP measurements < 50 mm Hg, treatment failure defined by a need for concurrent antihypertensive infusion, and frequency of elevated serum triglycerides > 200 mg/dL. Descriptive data were expressed as frequency with percentage or median with interquartile range as appropriate. Analysis of continuous outcome variable data involved Mann-Whitney U-tests with an alpha significance of 0.05.

RESULTS
Data from 47 patients were included in the analysis. The average change in ICP from preinfusion baseline to 48 hours was < 1 mm Hg. Of 3025 total postinfusion ICP measurements in 47 patients, 67 measurements (2.2%) in 13 patients (28%) were > 20 mm Hg. CPP measurements < 50 mm Hg occurred in 16 of 45 patients (36%). Three patients (6.4%) required use of a secondary antihypertensive medication infusion, and 5 of 14 patients (36%) had serum triglycerides > 200 mg/dL.

CONCLUSIONS
Use of clevidipine had minimal effect on ICP. The results of this study suggest that clevidipine is effective at safely maintaining ICP and CPP measurements without detrimental adverse effects in pediatric neurosurgical patients.
