Subcortical Ischemic Vascular Cognitive Impairment: Insights from Reaction Time Measures
Authors: Richards Emma , Bayer Antony , Tree Jeremy J. , Hanley Claire , Norris Jade E. , Tales Andrea
Published: October 2019

In this study, reaction time (RT), intraindividual variability (IIV), and errors, and the effects of practice and processing load upon such function, were compared in patients with subcortical ischemic vascular cognitive impairment (SIVCI) [ n = 27] and cognitively healthy older adults (CH) [ n = 26]. Compared to CH aging, SIVCI was characterized by a profile of significantly slowed RT, raised IIV, and higher error levels, particularly in the presence of distracting stimuli, indicating that the integrity and/or accessibility of the additional functions required to support high processing load, serial search strategies, are reduced in SIVCI. Furthermore, although practice speeded RT in SIVCI, unlike CH, practice did not lead to an improvement in IIV. This indicates that improvement in RT in SIVCI can in fact mask an abnormally high degree of IIV. Because IIV appears more related to disease, function, and health than RT, its status and potential for change may represent a particularly meaningful, and relevant, disease characteristic of SIVCI. Finally, a high level of within-group variation in the above measures was another characteristic of SIVCI, with such processing heterogeneity in patients with ostensibly the same diagnosis, possibly related to individual variation in pathological load. Detailed measurement of RT, IIV, errors, and practice effects therefore reveal a degree of functional impairment in brain processing not apparent by measuring RT in isolation.

The Transition from Standing to Walking Is Affected in People with Parkinson’s Disease and Freezing of Gait
Authors: Amundsen Huffmaster Sommer L. , Lu Chiahao , Tuite Paul J. , MacKinnon Colum D.
Published: October 2019

Background:

It has been hypothesized that freezing of gait (FOG) in people with Parkinson’s disease (PD) is due to abnormal coupling between posture and gait.

Objective:

In this study, we examined the relationship between anticipatory postural adjustments (APAs) preceding gait initiation and the kinematics of the first two steps between people with FOG and without FOG.

Methods:

The kinetics and kinematics of self-initiated gait were recorded in 25 people with PD (11 with FOG, 14 without FOG). Outcome variables included the amplitude and timing of the ground reaction forces (GRFs), center of pressure (CoP) shifts and the spatial and temporal characteristics of the first and second steps.

Results:

The magnitude and timing of the APA phase of gait initiation were not significantly different between participants with and without FOG, yet the first step in the FOG group was distinguished by a significantly wider and less variable first step width, followed by a subsequent wider and shortened second step with reduced toe clearance. Multiple linear regression showed that the relationship between the initial conditions (stance width), APAs (posterior shift of the CoP) and the kinematics of the first step were different between groups with a significantly increased slope in the FOG group.

Conclusion:

These findings demonstrate that the transition from standing to walking is different between those with and without FOG and that alterations in the initial conditions or APAs are more likely to impact the execution of the two steps in people with FOG.
Preparation, characterization and luminescence of (SBA-15)-Ag2 S nanocomposite material
Authors: Wang Qing-Shuang , Zhai Qing-Zhou
Published: October 2019

SBA-15 mesoporous molecular sieve was prepared using triblock copolymer poly (ethylene glycol)-block-poly (propylene glycol)-block (poly ethylene glycol) as the template, tetraethyl orthosilicate as the silica source in acidic medium. Through toluene/water two-phase interface, nano Ag2S guest has been synthesized. By thermal diffusion method, (SBA-15)-Ag2S host-guest nanocomposite material was prepared. The results of powder X-ray diffraction (XRD) showed that the silver sulfide assembled did not destroy the molecular sieve skeleton and the host-guest nanocomposite prepared still maintained good crystallinity. Infrared spectra showed that the host molecular sieve skeleton in the composite material was intact. Transmission electron microscopic results showed that the pores of SBA-15 after loading of Ag2S were obvious and not damaged. The nitrogen adsorption-desorption results at 77 K showed that the guest has already partly occupied the molecular sieve pores, which led to the decrease in the pore volume and specific surface area to some extent. UV-Vis reflection spectra showed that Ag2S molecules were well assembled into SBA-15 and the molecules presented a highly dispersed state. The luminescent research results showed that the (SBA-15)-Ag2S nanocomposites after the encapsulation have luminescent phenomena and the luminescence is stronger than that of the Ag2S. The (SBA-15)-Ag2S nanocomposites have obvious emission peaks at 425 nm, which has a potential applied prospect as a light emitting diode etc optical material.

Authors: El Sheikh Ragaa , Atwa Mohammed , Gouda Ayman , Abdullah Amira
Published: October 2019

A new, green, and simple cloud point extraction process of aluminum (III) from aqueous solution was investigated. The method is based on the complexation reaction of aluminum (III) with alizarin red S (ARS) at pH 5.0 and micelle-mediated extraction of the complex with nonionic surfactant Triton X-114. The enriched analyte in the surfactant-rich phase was determined spectrophotometrically at 515 nm. The optimal conditions including pH, reagent volume, surfactant concentration, temperature and centrifugation time were optimized. The proposed CPE method showed linear calibration within the range 5.0–300 ng mL–1 of aluminum (III) and the limit of detection was 1.0 ng mL–1 with a preconcentration factor of ∼100. The relative standard deviation (RSD%) and relative error (RE%) were found to be 1.70% and 1.78%, respectively. The accuracy of method was evaluated by the analysis of certified reference materials. The interference effect of some cations and anions was also studied. In the presence of foreign ions, no significant interference was observed. The method was applied to the determination of aluminum (III) in real food samples with a recovery for the spiked samples in the range of 95.0–102%.

The reaction of propargyl chloride with As(III) and S(IV) nucleophiles
Authors: Ioannou Panayiotis V. , Vachliotis Dimitris G. , Kouli Ourania
Published: October 2019

Propargyl chloride, CH≡C–CH2Cl, was virtually inert towards NaH2AsO3, reacted to a very small extent with Na2HAsO3, but with Na3AsO3 gave a mixture of salts in which sodium 1-propynylarsonate, CH3–C≡C–AsO3Na2 6, predominated, the allenylarsonate, CH2 = C = CH–AsO3Na2 4, being present in (very) small amounts, while the isomeric 2-propynylarsonate CH≡C–CH2–AsO3Na2 5 was not detected. These results can be understood by attack of AsO33– on propargyl chloride to form 5 followed by base catalyzed prototropic rearrangements to 4 and to 6. Separation of 6 from 4 was tried as acids or salts without success. The purity of the product as acid 6 and lead salt of 6 was >80%. The reaction of propargyl chloride with Na2SO3 required dilute aqueous solutions (∼0.3 M) in order to give the salt CH≡C–CH2–SO3Na·4H2O, 11·4H2O, in ∼80% yields. More concentrated solutions (1 or 2 M) produced 11 and by-products from which CH2 = C = CH-SO3Na 10, but not CH3–C≡C–SO3Na 12, has been identified spectroscopically, while potassium 2-chloro-2-propenylsulfonate tetrahydrate CH2 = CCl–CH2–SO3K·4H2O, 13·4H2O, was isolated.

Authors: Ioannou Panayiotis V. , Vachliotis Dimitris G.
Published: October 2019

From the arsonolipids (2,3-diacyloxypropylarsonic acids, 1) the stearoyl and palmitoyl are not reduced by ascorbic acid/iodine in methanol while the myristoyl and lauroyl arsonolipids are reduced to the arsenoso compounds 3. The reaction of arsenoso compounds 3 and of arsonolipids 1 with L-cysteine (cysSH), L-cysteine hydrochloride (cysSH·HCl) and glutathione (GSH) under various conditions was studied. Lipo-dithioarsonites [R-As(SR′)2] 4 have been isolated with GSH with both lipids 1 and 3. The product 4 was obtained only from 3 and cysSH. The salt cysSH·HCl reacted with 3 in methanol but gave it back on attempts at isolation of 4, while in DMSO unknown products were obtained. The arsonolipids 1 can be components of biological membranes and all lipo-dithioarsonites 4 prepared were insoluble in water and once formed must remain anchored in a membrane, thus altering its properties.

Authors: Demir Funda , Moroydor Derun Emek
Published: October 2019

In today’s world, heavy metal pollution is one of the major problems. Various methods have been developed for the removal of pollution caused by heavy metals. However, adsorption is the most advantageous process among these methods.

Mining waste is another source of pollution. The evaluation of these wastes will both solve the storage problems and prevent environmental pollution.

In this study, Bergama gold mine wastes were evaluated and used in geopolymer production. Alkaline fusion method was used for geopolymer synthesis in the experimental process. The obtained geopolymer sample was suitable for adsorption in terms of porosity and surface area and was used in the adsorption of Cu2+.

According to the results of the studies, the surface area of the gold mine waste increased from 3.845 m2/g to 74.916 m2/g. Adsorption studies were carried out at different parameters such as geopolymer dosage, contact time, temperature and initial concentration. Also, isotherm and kinetic studies were applied. Cu2+ adsorption is suitable for the Langmuir isotherm model (R2 = 1) and the Pseudo-second order kinetic model (R2 = 0.997).

Published: October 2019

INTRODUCTION:

Diet quality indices are an approach to estimate entire diet quality. This study aims to determine the association between Mean Adequacy Ratio (MAR) as a diet quality indicator and anthropometric indices in children and adolescents.

METHODS:

This is a nationwide cross-sectional study. In the present study, 5000 students randomly were selected for filling the food frequency questionnaire. Multivariate linear regression analysis was used to evaluate the association between MAR with anthropometric measures – Z score.

RESULTS:

Data of 4323 children and adolescents aged 6–18 years old were available for the present study. In total, 52.5% of them were boys. The mean (standard deviation) ages were 11.2 (3.2) and 11.5 (3.1) years for boys and girls, respectively. Result of multivariate regression analysis showed that MAR was positively associated with waist circumference- Z score and BMI- Z score ( β= 0.399, P < 0.001; β= 0.291, P = 0.001, respectively).

CONCLUSIONS:

We found a positive association between waist circumference-Z score and BMI-Z score with MAR.
False negative diagnoses of critical congenital heart disease with screening neonatal pulse oximetry
Authors: Hoffman J.I.E.
Published: October 2019

BACKGROUND:

False negative pulse oximeter results occur in new born infants with critical congenital heart disease who have an oximeter saturation ≥95%. Some of these infants have abnormal physical findings but others do not.

OBJECTIVES:

To determine the causes of false negative results.

METHODS:

Mathematical analysis of determinants of arterial oxygen saturation and discussion of oximeter bias.

RESULTS:

False negative oximeter results are not rare; the sensitivity of pulse oximetry screening for critical congenital heart disease is about 80%. The high saturation may be due to a very small right-to-left shunt at the time of study, a relatively high cardiac output and mixed venous saturation, or to positive bias in oximeter readings. It may also be due to some critical congenital heart lesions that do not show desaturation at the time of testing.

CONCLUSIONS:

A diagnosis of a normal heart based on a negative oximeter test is presumptive, and requires careful follow-up for 1–2 weeks after birth.
A physiological approach to fluid and electrolyte management of the preterm infant: Review
Authors: Segar J.L.
Published: October 2019

Despite the fact that hundreds of thousands of preterm infants receive parenteral fluids each year, study of optimal fluid and electrolyte management in this population is limited. Compared to older children and adults, preterm infants have an impaired capacity to regulate water and electrolyte balance. Appropriate fluid and electrolyte management is critical for optimal care of low birth weight or sick infants, as fluid overload and electrolyte abnormalities pose significant morbidity. This review highlights basic physiological principles which need to be applied when prescribing parenteral fluids and builds upon published literature to outline a rational approach to initial fluid and electrolyte management of the preterm infant.

Authors: Wang Yi , Liu Shanshan , Lou Shiliang , Zhang Weiqian , Cai Huaiyu , Chen Xiaodong
Published: October 2019

BACKGROUND:

Optical coherence tomography (OCT) is a non-invasive diagnosing tool used in clinics. Due to its high resolution (<10um), it is appropriate for the early detection of tiny infections. It has been widely used in diagnosis and treatment of diseases, evaluation of therapeutic efficacy, and monitoring of various physiological and pathological processes.

OBJECTIVE:

To systemically review literature to summarize the clinic application of OCT in recent years.

METHODS:

For clinic applications that OCT has been applied, we selected studies that describe the most relevant works. The discussion included: 1) which tissue could be used in the OCT detection, 2) which character of different tissue could be used as diagnosing criteria, 3) which diseases and pathological process have been diagnosed or monitored using OCT imaging, and 4) the recent development of clinic OCT diagnosing.

RESULTS:

The literature showed that the OCT had been listed as a routine test choice for ophthalmic diseases, while the first commercial product for cardiovascular OCT detection had gotten clearance. Meanwhile, as the development of commercial benchtop OCT equipment and tiny fiber probe, the commercial application of OCT in dermatology, dentistry, gastroenterology and urology also had great potential in the near future.

CONCLUSIONS:

The analysis and discussions showed that OCT, as an optical diagnosing method, has been used successfully in many clinical fields, and has the potential to be a standard inspection method in several clinic fields, such as dermatology, dentistry and cardiovascular.

Published: October 2019

Background: Maternal health remains today, one of the major public health concerns in developing countries. Maternal deaths and newborn deaths usually occur within 48 hours of delivery. In Cameroon, despite all the initiatives set up by the Ministry of Public Health to reduce the mortality rate, the situation remains alarming in terms of postnatal consultation; this is much more felt in the West region of Cameroon, which is one of the most affected regions because 43.1% of women who give birth in hospitals do not return to postnatal consultation and this rate is higher than the national average with a value of 21.5%. Objective:This work aims to determine the factors influencing postnatal follow-up in the Bafang Health District. Methodology: This is a cross-sectional descriptive study for analytical purposes, carried out in the Bafang Health District between January 1 to November 30, 2017. Our study population consisted of all women of childbearing age living in the Bafang Health District during the study period. The variables studied were sociodemographic characteristics, socio-cultural characteristics and the provision of care. Results: Analysis carried out during this study, it appears that, the person who informs the women on the dates of rendez-vous during the CPoN (OR = 2.92; [95%CI = 1.16-7,]; p-value = 0.02), women who think the appropriate period of postnatal follow-up is 6 weeks postpartum (OR = 4.27, [95%CI = 1.47-12.39], p-value = 0.00 ) and those who massage the abdomen after childbirth (OR = 2.62, [95%CI = 1.34 - 5.12], p-value = 0.00) are more likely to have knowledge about follow-up postnatal. While women who have no knowledge of postnatal follow-up (OR = 0.18, 95%CI = 0.07-0.45, p-value = 0.00) are less likely to have more knowledge. Conclusion: Lack of knowledge of the existence and importance of postnatal consultation (CPoN), traditional practices are the factors that influence postnatal follow-up in the Bafang Health District. A good and effective care for women after childbirth requires increased awareness campaigns at the hospital level as well as in community settings.

Authors: Al-Homaidy Mohammed
Published: October 2019

Toward answering a complicated question of considering financial low-risk and fixed income instruments a safe haven for rentier economies, this study investigates the perspectives and perceptions of policy makers and non- policy makers of a rentier economy of Saudi Arabia, the largest oil producer, towards investing its financial reserves, initially, in the financial sector and, particularly fixed-income securities. Furthermore, the study explores experts’ views in regard to the optimal alternative to the investment in an financial sector. The outcomes of this research methods: interview and questionnaire, show that, despite the uncertainty and instability featured the present financial investment scene, manifested by the current economic slowdown and financial crisis: balance sheet recession, market crunches and banking collapse in different parts of the world, the majority of the participants, trusted the financial sector as a shelter for the reserves of Saudi Arabia. They believed that government bonds and T-bills are the most secure financial instruments to invest the accumulated revenues from oil returns. Thus, from the participants responses, the financial investment sector represents the acceptability framework that can be a safe channel to maximize income for the national economy.

Insurance is a crucial component of any financial sector, the financial soundness of the insurance sector will result in a healthier financial system in any country. The insurance sector is responsible for transferring risk from one entity to another, for premium, to hedge against any risk of unexpected loss. For that, the insurance sector plays the role of safety net for the whole of the financial system in any country. This study aims to detect the existence of signs of financial failure for conventional insurance companies listed at Kuwait stock exchange (KSE). The study uses the Altman Model to calculate the financial failure indicators. The research also measures the relationship between the financial failure score and the share price of these companies. The analysis is based on the belief that financial reports provide information to investors which can be taken as indicators of the financial failure or success of companies. This information will affect investment decisions which, in turn, will be reflected on the share price. This study is based on the financial data of conventional insurance companies listed at Kuwait stock exchange for the period spanning from 2010 to 2017. A panel data collected from the financial statements of the four conventional insurance companies listed at the stock market were used to calculate the financial failure score for these companies. Ordinary least squared (OLS) regression method, is then used to evaluate the relation between Altman’s z-score and the share price of these companies. Results obtained from this study showed that conventional insurance companies operating in Kuwait had a healthy financial positions and therefore safe from bankruptcy risk. The study also revealed that there was no statistically significant relation between Altman’s score and the share price indicating that the financial failure score does not have an effect on share price of conventional insurance companies listed at Kuwait stock exchange.
