OBJECTIVE

From 1994 to 2006 outpatient spinal surgery increased 5-fold. The perceived cost savings with outcomes comparable to or better than those achieved with inpatient admission for the same procedures are desirable in an era where health expenditures are scrutinized. The increase in outpatient spine surgery is also driven by the proliferation of ambulatory surgery centers. In this study, the authors hypothesized that the total savings in outpatient spine surgery is largely driven by patient selection and biases toward healthier patients.

METHODS

A meta-analysis assessed patient selection factors and outcomes associated with outpatient spine procedures. Pooled odds ratios and mean differences were calculated using a Bayesian random-effects model. The authors extended this analysis in a novel way by using the results of the meta-analysis to examine cost data from an administrative database of academically affiliated hospitals. A Bayesian approach with priors informed by the meta-analysis was used to compare costs for inpatient and outpatient performance of anterior cervical discectomy and fusion (ACDF) and lumbar laminectomy.

RESULTS

Sixteen studies with a total of 370,195 patients met the inclusion criteria. Outpatient procedures were associated with younger patient age (mean difference [MD] −2.34, 95% credible interval [CrI] −4.39 to −0.34) and no diabetes diagnosis (odds ratio [OR] 0.78, 95% CrI 0.54–0.97). Outpatient procedures were associated with a lower likelihood of reoperation (OR 0.42, 95% CrI 0.16–0.80), 30-day readmission (OR 0.39, 95% CrI 0.16–0.74), and complications (OR 0.29, 95% CrI 0.15–0.50) and with lower overall costs (MD −$121,392.72, 95% CrI −$216,824.81 to −$23,632.92). Additional analysis of the national administrative data revealed more modest cost savings than those found in the meta-analysis for outpatient spine surgeries relative to inpatient spine surgeries. Estimated cost savings for both younger patients ($555 for those age 30–35 years [95% CrI −$733 to −$374]) and older patients ($7290 for those age 65–70 years [95% CrI −$7380 to −$7190]) were less than the overall cost savings found in the meta-analysis.

CONCLUSIONS

Compared to inpatient spine surgery, outpatient spine surgery was associated with better short-term outcomes and an initial reduction in direct costs. A selection bias for outpatient procedures toward younger, healthier patients may confound these results. The additional analysis of the national database suggests that cost savings in the outpatient setting may be less than previously reported and a result of outpatient procedures being offered more frequently to younger and healthier individuals.
Long-term follow-up for patients with infantile hydrocephalus treated by choroid plexus coagulation
Authors: Okano Atsushi , Ogiwara Hideki
Published: September 2018

OBJECTIVE

Shunt surgery is the most common treatment for hydrocephalus, but it is associated with several long-term complications. Endoscopic choroid plexus coagulation (CPC) and endoscopic third ventriculostomy (ETV) are alternative surgeries that may avoid the need for shunt surgery. Although the short-term efficacy and safety of CPC have been reported in previous studies, long-term outcome, including not only avoiding shunt placement but also intellectual development, remains to be elucidated. The purpose of the present study was to investigate the long-term outcome of CPC.

METHODS

The study population comprised patients who had infantile hydrocephalus treated by endoscopic CPC before the age of 24 months and who were followed until at least 5 years of age. Retrospective review was performed using the medical charts. The authors assessed educational status and the full-scale intelligence quotient (FSIQ) using the Wechsler Intelligence Scale for Children (WISC) IV as the means to evaluate the intellectual development.

RESULTS

Fourteen patients with infantile hydrocephalus underwent CPC with or without ETV as a primary surgery. There were no intraoperative complications. In 7 patients (50%), hydrocephalus was successfully controlled without shunt placement. Six patients (43%) eventually required shunt placement. In one patient hydrocephalus was controlled by additional ETV. In the shunt-independent group, 4 patients went to age-appropriate school or achieved age-appropriate development according to intelligence quotient (IQ), 1 patient went to specialized school, and 2 patients had disabilities. In the shunt-dependent group, 4 patients went to an age-appropriate school or achieved age-appropriate development by IQ, 1 patient went to specialized school, and 1 patient had disabilities. The mean FSIQ score in 3 patients without shunts was 90 (range 89–91) and the mean FSIQ score in 4 patients with shunts was 80 (range 48–107). There was no significant difference in the rate of normal development between the shunt-independent group and the shunt-dependent group (p = 0.72).

CONCLUSIONS

The CPC with or without ETV can be a safe and effective treatment in children with infantile hydrocephalus. Long-term control of hydrocephalus and normal intellectual development can be achieved in successful cases. Further prospective studies should be required to elucidate appropriate indications.

Characteristic scales of bounded L2 sequences
Authors: Erceg Marko , Lazar Martin
Published: September 2018

Practical applications of semiclassical measures are tightly connected with a so called oscillatory property, prevailing leakage of information related to high frequencies. In this paper we propose a complementary, concentratory property which prevents loss of information related to low frequencies. We demonstrate that semiclassical measures attain the best performance level if both the properties are satisfied simultaneously, and address a question if this is possible to achieve for an arbitrary bounded [Formula: see text] sequence, providing a negative answer. Comparison of H-measures with semiclassical ones is presented, showing precedence of the latter for problems exhibiting just a single frequency scale. Finally, we present some (strong) compactness results based on the above properties.

Published: September 2018

Background:

Recent studies suggest a link between periodontitis and Alzheimer’s disease (AD).

Objective:

Verification of the presence of periodontal pathogens and the intrathecal generation of pathogen-specific antibodies in 20 patients with AD and 20 with other forms of dementia (DEM-noAD).

Methods:

Clinical periodontal indices were recorded. Cerebrospinal fluid (CSF) was analyzed for total tau protein (T-tau) and amyloid-β (Aβ1-42). In serum and CSF, antibody levels against Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Treponema species were quantified. The presence of selected bacteria and inflammatory biomarkers were determined in periodontium, serum, and CSF.

Results:

In line with diagnoses, CSF-levels of Aβ1-42 were significantly lower in AD than DEM-noAD patients. Periodontal destruction and inflammation were omnipresent with no difference between groups. P. gingivalis, T. forsythia, and Treponema species were detected in more than 50% of subgingival biofilm samples, but neither in serum nor in the CSF. Elevated levels of anti-pathogen antibodies in CSF of 16 patients (7 AD; 9 DEM-noAD) compared to serum highlight a possibility of the intrathecal immune response to pathogens. There was no significant difference in antibodies levels against selected bacteria in CSF and serum between groups. Multivariate regression analysis and general linear models revealed an association of the T-tau level in AD group with both serum levels of anti- P. gingivalis antibodies and MCP-1/CCL-2.

Conclusion:

Periodontal pathogens may enter the brain and stimulate a local immune response. However, in patients with dementia at the age up to 70 years, periodontal pathogens do not act as a trigger for developing AD.

Published: September 2018

OBJECTIVE:

Correlation between myocardial infarction (MI) scar by cardiac magnetic resonance and the Lown’s classification of ventricular premature beats (VPBs) is poorly understood. This study aims to investigate the correlation between the MI scar characteristics by delayed-enhancement magnetic resonance imaging (DE-MRI) and the Lown’s classification of VPBs.

METHODS:

Sixty-five patients, in the convalescence stage and consolidation phase of MI, were included in this retrospective study. All patient were divided into VPBs group ( n = 39) and non-VPBs group ( n = 26 patients) according to the clinical diagnostic criteria of Universal Definition of MI scar. VPBs patients were assigned to Lown’s I-II group and Lown’s III-IV subgroup in accordance with the Lown classification criteria. Cardiac function parameters and MI scar characteristics were detected by cardiac magnetic resonance (CMR) and DE-MRI, respectively.

RESULTS:

Lown’s classification was negatively correlated with left ventricular ejection fraction (LVEF), peak ejection rate (PER) and peak filling rate (PFR) (–0.724, –0.628, –0.559), and positively correlated with MI area, MI integral, MI segments number and left ventricular end systolic volume (LVESV) (0.673, 0.655, 0.586, and 0.514), respectively.

CONCLUSIONS

The study indicated that MI area and MI integral were strongly associated with Lown’s classification.

Die Evolution indigener Politik in Bolivien
Authors: Rice Roberta
Published: September 2018

This study examines the emergence of indigenous movements as powerful new social and political actors in Latin America. Bolivia’s indigenous movement, in particular, stands out for its mobilizational and organizational capacity in uniting diverse sectors of civil society in the struggle against neoliberalism. The study explores the evolution of indigenous movement strategies in Bolivia, beginning from the transition to democracy in the early 1980s until the presidential victory of indigenous leader Evo Morales of the Movement Toward Socialism (MAS) party in late 2005. Special attention is paid to the rise of contemporary indigenous-based parties rooted in established social movement organizations as well as the role of the indigenous movement in the Bolivian ‘Water War’ of 2000 and the ‘Gas War’ of 2003. The study contends that the success of Bolivia’s contemporary indigenous movement is largely the result of its two-pronged strategy based on unwavering opposition in both the streets and in parliament and its capacity to combine competing class- and ethnic- based demands.

A vision anti-sway control algorithm for container cranes
Authors: Quoc Chi Nguyen , Tien Khang Nguyen
Published: September 2018

In this paper, a control scheme is proposed for an automated container crane. The proposed control scheme includes position control (for the trolley) and sway control algorithms (for the payload) where PID control is used for position control and PD control is assigned for sway control. The proposed control scheme employs the feedback signal of the sway angle, which is acquired by a vision system. The idea to employ the vision system is to overcome the difficulty in installing a conventional sensor system for measuring the sway angle. Numerical simulations and experiments have been carried out to verify the effectiveness of the proposed control scheme.
Effect of temperature and porosities on dynamic response of functionally graded beams carrying a moving load
Authors: Bui Tuyen Van
Published: September 2018

The effect of temperature and porosities on the dynamic response of functionally graded beams carrying a moving load is investigated. Uniform and nonlinear temperature distributions in the beam thickness are considered. The material properties are assumed to be temperature dependent and they are graded in the thickness direction by a power-law distribution. A modified rule of mixture, taking the porosities into consideration, is adopted to evaluate the effective material properties. Based on Euler-Bernoulli beam theory, equations of motion are derived and they are solved by a finite element formulation in combination with the Newmark method. Numerical results show that the dynamic amplification factor increases by the increase of the temperature rise and the porosity volume fraction. The increase of the dynamic amplification factor by the temperature rise is more significant by the uniform temperature rise and for the beam associated with a higher grading index.
Nonlinear analysis of thermal behavior for a small satellite in Low Earth Orbit using many-node model
Authors: Pham Chung Ngoc , Nguyen Anh Dong , Nguyen Hieu Nhu
Published: September 2018

In this paper, nonlinear thermal responses of a small satellite in Low Earth Orbit (LEO) are analyzed using many-node model. The main elements of primary structure of the satellite include six rectangular cover plates and a solar array linking with satellite's body. These elements can be modeled as different lumped thermal nodes. We use an eight-node model for estimating temperatures at nodal elements i.e. six nodes for cover plates, and two nodes for front and rear surfaces of the solar array. The nodes absorb three major heat energy sources from the space environment consisting of solar irradiation, Earth’s albedo and infrared radiation. The established system of thermal balance equations for nodes is nonlinear and is solved by a numerical algorithm. For simulation purpose, it is assumed that the satellite always remains Earth-pointing attitude during motion. Temperature evolutions of nodes in time are explored in details. The obtained results show that the predictive temperature values of nodes are within the allowable temperature limit range of the satellite.

Cervical disease is one of the common diseases, it occurs in women and has a growing tendency. In particular, cervical cancer is one of the most common diseases. The disease can be cured if it is detected early and treated under the guidance of a physician. The usual cervical examination methods are biopsies, and colposcopy. Recently, many studies have applied imaging techniques in the analysis and evaluation of cervical pathology characteristics [1-3]. In this study, we improved the traditional colposcopy with a polarized light source, and captured images with high resolution. Based on the image obtained, we developed image processing algorithms, initially analyzed and evaluated some of the common features of cervical disease
Generalized Knaster-Kuratowski-Mazurkiewicz type theorems and applications to minimax inequalities
Authors: Ha Linh Manh
Published: September 2018

Knaster-Kuratowski-Mazurkiewicz type theorems play an important role in nonlinear analysis, optimization, and applied mathematics. Since the first well-known result, many international efforts have been made to develop sufficient conditions for the existence of points intersection (and their applications) in increasingly general settings: Gconvex spaces [21, 23], L-convex spaces [12], and FCspaces [8, 9]. Applications of Knaster-Kuratowski-Mazurkiewicz type theorems, especially in existence studies for variational inequalities, equilibrium problems and more general settings have been obtained by many authors, see e.g. recent papers [1, 2, 3, 8, 18, 24, 26] and the references therein. In this paper we propose a definition of generalized KnasterKuratowski-Mazurkiewicz mappings to encompass R-KKM mappings [5], L-KKM mappings [11], T-KKM mappings [18, 19], and many recent existing mappings. Knaster-KuratowskiMazurkiewicz type theorems are established in general topological spaces to generalize known results. As applications, we develop in detail general types of minimax theorems. Our results are shown to improve or include as special cases several recent ones in the literature.

Trade relationship between Vietnam and Japan: Current situation and trend
Authors: Le Loc Tuan
Published: September 2018

Using the Comparative Advantage Theory, models to evaluate trade relationship and data of the United Nations, the study analyzes the relationship between Vietnam and Japan in the period 2001 -2015. Japan is the largest trading partner of Vietnam with trade volume steadily increasing and equal bilateral trade volumes. Results indicate that the high Vietnam – Japan trade intensity reflects the importance of Japan to Vietnam in international trade. The bilateral trade of these two countries tends to be extraindustry, to which Vietnam exports to Japan comparative advantage products such as agricultural and labor-intensive products while Japan exports to Vietnam machine, equipment and input materials. Vietnam – Japan trade relationship is projected to keep expanding owing to continuously improved bilateral political and economic relationship.

The impact of market timing on capital structure: Evidence from Vietnamese listed companies
Authors: Ngo Tra Thanh , Tran Tuyen Van , Nguyen Diep Van
Published: September 2018

This study uses the theory of market timing in considering capital structure of the sample of 430 companies which are listed on Vietnam's stock market and implemented IPO in the period of 2006 - 2012. Following the research method of Alti (2006), the article used the variable HOT to represent the factor of market timing in order to understand the relationship between this variable and leverage variable in the short-term (in the year of IPO) and in the long-term (year of IPO + 1, IPO + 2, ..., IPO + 6). The results showed no statistically significant evidence about the negative relationship between the HOT and leverage ratios. It implies that in the first time that companies issue their share capital to the public, the ―active‖ or ―gloomy‖ situation of market is not related to the leverage ratio at the moment of observation. In addition, the results also showed that variables relating to characteristics of company such as growth potential, profitability and scale have a statistically significant relation to capital structure and tangible has no impact on leverage ratio.

Slump Loss of Concrete Based on RCA and Prepared by Specific Mixing Approach
Authors: Sičáková Alena , Urbán Karol , Kováč Marek
Published: September 2018

Concrete is a dynamic material and its consistency changes with time, having impact on technological processes at working site. It is expressed due to slump loss - the reduction in slump from the time of original batching to the point when concrete is discharged from a truck mixer. Two kinds of additives (fly ash and recycled concrete powder) were tested to find their potential to improve the performance of recycled concrete aggregate in concrete, while the principle of triple-mixing method was adopted. Slump loss was evaluated based on measurements taken at 0, 45, and 90 minutes after mixing. The kind of aggregate, as well as kind of powdery material for coating the coarse fractions play significant role for the slump loss. Mixtures with fly ash as coating material achieved the biggest slump loss for both types of aggregate. The recycled concrete powder is well acceptable having similar impact on the slump loss as the cement has. When the NA is changed to RCA, the slump loss is higher and depends on material used for coating.

Authors: Komurlu Eren , Demir Serhat
Published: September 2018

In this study, a new direct tensile strength determination method of drilled core specimen testing was investigated with numerical and experimental studies. Effect of different drill diameters of holes of the rock specimens was analysed to assess the ideal drill-hole design. The aim of drilling process is decreasing the failure load and stress concentration at the adhesive part to prevent invalid failures. Drilled specimens were determined to fail due to the start of cracking under the condition of uniaxial tensile stress distribution at sidewalls of holes. It was found that drill bits with the diameter of 11 mm is usable for a practical specimen drilling process to make a significant decrease in the failure load of the core specimens with the NX size (@54 mm) diameter. According to the results obtained from numerical and experimental analyses, an equation was suggested to determine uniaxial tensile strength values of drilled core specimens with the hole diameter of 11 mm.

For the planning of future research and development elaborate information and a reliable database on existing cropping patterns, cropping intensity and crop diversity of a particular area are of prime importance for guiding policy makers, researchers, extensionists and development workers. A massive group work was accomplished over all 35 upazilas of Rangpur region during 2016 using pre-tested semistructured questionnaire with a view to document the existing cropping patterns, cropping intensity and crop diversity in the area. Boro−Fallow−T. Aman occupied the largest portion (53%) of net cropped area (NCA) with its distribution in all upazilas. The second largest area, 5% of NCA, was covered by Maize−Fallow−T. Aman which was spread out over 23 upazilas. Under the current investigation 134 cropping patterns were identified. The highest number of cropping patterns was identified 31 in Badarganj of Rangpur and the lowest was 10 in Razibpur of Kurigram district. The highest value of CDI was observed 0.991 in Razibpur upazila followed by 0.989 in Chilmari of Kurigram. The range of cropping intensity values was recorded 190-255%. The maximum value was for Gangachara upazila of Rangpur and minimum for Gaibandha sadar upazila. The overall CDI of Rangpur region was calculated 0.871 and the average cropping intensity at regional level was 219%.Bangladesh Rice j. 2017, 21(2): 255-271

Published: September 2018

Background: Hypertension is one of the most important noncommunicable diseases. Presence of other cardiovascular risk factors in hypertensive patients increases the risk of ischaemic heart disease and cerebrovascular diseases. We evaluated the prevalence of cardiovascular risk factors among the hypertensive patients.Methods: Patients presenting to the outpatient department of a secondary hospital were included in the study. The prevalence of diabetes mellitus, current smoking, family history of ishaemic heart disease, dyslipidaemia and nephropathy were evaluated.Results: A total of 144 patients were included in the study (male 66 & female 78). 29.8% patients were smoker (57% of male patients and 6% of female patients); 34% patients were diabetic; 27% patients had raised total cholesterol, 40.3% had reduced HDL, 22% had raised LDL, 36.8% had raised triglyceride and 33.3% patients had nephropathy (proteinuria/ raised serum creatinine).Conclusion: The prevalence of cardiovascular risk factors, specifically smoking, diabetes mellitus, raised LDL and nephropathy were more among the hypertensive patients. All the hypertensive patients should be evaluated for modifiable cardiovascular risk factors during diagnosis and follow up. Treatment of these risk factors can improve the prognosis of the hypertensive patients.Cardiovasc. j. 2018; 11(1): 10-16

Background: Acute kidney injury (AKI) is a risk factor for long-term adverse outcomes, including acute myocardial infarction and death. The objective of this study was to find out in-hospital outcomes in patients with acute ST elevation myocardial infarction with acute kidney injury.Methods: A total 190 patients were included in this study and were equally divided into two groups, Group-I (with AKI) and Group-II (without AKI), according to absolute changes of serum creatinine level. AKI was defined as absolute changes in serum creatinine (SCr. at 48 hours’ minus admission SCr) and categorized as mild AKI (increase of 0.3 to <0.5 mg/d), moderate AKI (increase of 0.5 to <1.0 mg/dl), and severe AKI (increase of e”1.0 mg/dl) using Acute Kidney Injury Network (AKIN) criteria.Results: Overall in-hospital mortality rate was 14.7% in Group-I (mortality rate for those with mild, moderate, and severe AKI were 7%, 13.3%, and 31.8%) compared with 5.3% in Group-II. Regarding inhospital morbidities, significant arrhythmia (29.5%) was the most common complication followed by acute heart failure (18.9%), cardiogenic shock (12.6%), and mechanical complications (4.2%) which were more in Group-I compared to patients with Group-II. After adjustment of other risk variables, the multivariate logistic regression analysis revealed AKI remained an independent predictor of in-hospital mortality with adjusted odds ratios (OR) was 4.991 (95% confidence interval, 1.873-13.301).Conclusions: AKI is an independent predictor of in-hospital mortality and morbidity. It emphasizes the importance of efforts to identify risk factors and to prevent AKI during in-hospital management of acute STEMI patients.Cardiovasc. j. 2018; 11(1): 59-66

A field trial was conducted to evaluate the comparative effects of jatropha seedcake, chicken and kraal manures on selected soil properties, growth and yield of tomato in Zambia during the cropping season of 2012-13. A Randomized Complete Block Design (RCBD) with four replicates and six treatments, namely- jatropha seedcake (5.0 t ha-1), chicken manure (5.0 t ha-1), kraal manure (5.0 t ha-1), jatropha seedcake (2.5 t ha-1) + chicken manure (2.5 t ha-1), jatropha seedcake (2.5 t ha-1) + kraal manure (2.5 t ha-1) and control (0.0 t ha-1) was used. Soil total N, P, K, Ca, Mg, SOM, soil pH, bulk density, plant height, number of branches, number of fruits plant-1, and mean fruit weight effects were subsequently monitored. Organic manures significantly increased total N, available P, exchangeable K, Ca, Mg, SOM, soil pH, plant height, number of branches, number of fruits, mean fruit weight and yield of tomato compared to the control. Organic manures also significantly reduced soil bulk density compared to the control. Among the organic amendments treated alone, jatropha seedcake gave the highest yield of 28.62 t ha-1 compared to chicken manure (28.20 t ha-1) and kraal manure (27.50 t ha-1). Maximum yield benefits came from a mixture of jatropha seedcake + chicken manure (29.60 t ha-1)and jatropha seedcake + kraal manure (29.00 t ha- 1) which could have been due to balanced proportions of major nutrients required for tomato growth. Jatropha seedcake mostly performed favourably the same or better than chicken and kraal manures in many aspects.Int. J. Agril. Res. Innov. & Tech. 8 (1): 1-6, June, 2018

Green revolution started at mid of twentieth century was the answer of anxiousness reminded by Malthusian that food scarcity problems in relation with population growth. In concurrence with exploitation of fossil fuel for agriculture mechanization as well as agrochemicals in the form of inorganic fertilizer and pesticide, green revolution by introducing high yielding varieties of cereals and grains was able to nourish the world population by increasing productivity. Indeed, from beginning of mechanization with fossil fuel based as advised by Rudolf Diesel then Arrhenius would be affected to the release of CO2 to the atmosphere and consequently exaggerating climate change as suffered by current and future generations. Under green revolution based on cereals and grains affected forest conversion into open agricultural land, because both commodities are sun-loving crops, which are hate to the shade. On the other hand, to slow the severity of climate change natural forest must be conserved tightly. Entering third millennium demand of food production with ecologically friendly is stronger. Hence, green revolution needs to be amended into greener perspectives. Thus, implementation of agro-forestry into wide range of agro-ecological zone is urgently innovated. Fortunately, shade tolerant of root crops has significant advantage to be developed under agro-forestry. Under shade of forest canopy at basal forest strata, root crops are able to sequester CO2 to be converted into carbohydrate and other compounds to provide food for the dweller. Back to nature is not only a slogan, with root crops under agro-forestry is a reality; fresh root up to 30 t ha-1 can be harvested yearly as the source of food and renewable fuel as well. This potential is very worthy to improve and greening the existing green revolution to be more sustainable.Int. J. Agril. Res. Innov. & Tech. 8 (1): 26-37, June, 2018
