Background: Chronic pain is a persistent and among most prevalence issue in childhood the bio psychosocial model of pain which is a complex interplay contributes to pain symptoms. Disability has guided our understanding and treatment of pediatric pain. The exact cause of chronic pain is sometimes infectious.
Introduction: The inclusion of chronic pain and rehabilitation terms resulted in a search to treat pediatric pain, treatment requires a comprehension and multi-disciplinary approaches mostly relieved by psychological intervention. Currently it is unclear how accurate diagnosis is made by general practitioners and specialists and how evaluation is made by pain specialists can affect patient’s outcomes.
Case: A young adult female whose chronic hip and knee pain from several months was treated for pain, and osteoporosis, and osteomalacia, with calcium supplements, once Magnetic resonance imaging was done, it revealed that the patient is having fluid filled space in left hip when biopsied revealed chronic osteomyelitis.
Conclusion: Chronic pain in pediatrics may be associated to osteomalacia, or osteopenia, it may be infectious, may be due to malignancy or fracture, but it shall be investigated with MRI na biopsy if the pain persists and not reliving with analgesics and supplements. Ignorance of chronic osteomyelitis can have poor outcomes.

Published: September 2024

The Nazinga Game Ranch (NGR), located in the south-central region of Burkina Faso, was established to promote sustainable socio-economic development and the harmonious and sustainable management of wildlife resources. This article analyzes inter-institutional interactions in the governance of the Nazinga Game Ranch (NGR) within a context of state-centralized governance. It focuses on examining the conflicting, collaborative, and indifferent relationships between the local institutions involved. The study adopted a mixed-methods approach, incorporating a literature review, interviews, and focus groups. Data processing and analysis were carried out using R software. The results highlight that two institutions, namely the Forestry Administration (UGN) and the Village Hunting Committees (CVC), occupy a central position in the conflicts. Projects and programs were found to play a significant role, cooperating with most of the institutions involved, except for the prefecture and among themselves. Relationships of indifference were identified between the UGN's partner projects and programs, local associations, the CVCs, and the Village Development Committees (CVDs), as well as between the Guiaro prefecture and the municipal government, and between the municipal authorities of the two neighboring communes. The analysis in terms of intensity shows that the conflicts, although not reaching maximum intensity, affect the management of the NGR. Furthermore, some collaborations, particularly those involving NGOs, play a decisive role.
Study of Correlation of Vitamin B-12 Levels in Febrile Thrombocytopenia: A Hospital Based Cross Sectional Study
Authors: Sanketh S.J. , Kamagond Pavana kumar , Khanapure Shashidhar P
Published: September 2024

Background: Thrombocytopenia can occur in vitamin B12 deficiency due to ineffective hematopoiesis. Case reports link B12 deficiency with febrile thrombocytopenia, but larger scale correlational studies are lacking. We aimed to evaluate for a correlation between vitamin B12 levels and platelet counts in patients presenting with febrile thrombocytopenia.
Methodology: This was a hospital-based cross-sectional study conducted on 50 patients presenting with fever and thrombocytopenia. Vitamin B12 levels and platelet counts were measured. Correlation and comparative analyses were performed between B12 levels and platelet counts.
Results: Thirty-eight percent of patients were vitamin B12 deficient (<200pg/mL). Vitamin B12 level demonstrated significant moderate positive correlation with platelet count (r=0.427, p=0.002). Comparisons between deficiency groups showed significantly lower platelet count in the B12 deficient (85 x 109/L) versus sufficient group (112 x 109/L), (p=0.04). Linear regression identified vitamin B12 status as an independent predictor of platelet count when adjusted for confounders (B=0.18, p=0.01).
Conclusion: Vitamin B12 deficiency has a significant correlational association specifically with reduced platelet counts in the context of febrile presentations. Screening for B12 deficiency could help evaluate thrombocytopenia etiology and guide management.

Toward “all weather,” long record, and real‐time land surface temperature retrievals from microwave satellite observations
Authors: Prigent C. , Jimenez C. , Aires F.
Published: May 2016

The land surface temperature can be estimated from satellite passive microwave observations, with limited contamination from the clouds as compared to the infrared satellite retrievals. With ∼60% cloud cover in average over the globe, there is a need for “all weather,” long record, and real‐time estimates of land surface temperature (Ts) from microwaves. A simple yet accurate methodology is developed to derive the land surface temperature from microwave conical scanner observations, with the help of precalculated land surface microwave emissivities. Different tests are conducted to optimize the algorithms. The method is applied to the Special Sensor Microwave/Imagers (SSM/I) observations over 2 years, regardless of the cloud cover. The results are compared to infrared estimates from International Satellite Cloud Climatology Project (ISCCP) and from Advanced Along Track Scanning Radiometer (AATSR), under clear‐sky conditions. Limited biases are observed (∼0.5 K for both comparisons) with a root‐mean‐square error (RMSE) of ∼5 K, to be compared to the RMSE of ∼3.5 K between ISCCP et AATSR. Cloud contamination in the AATSR estimates have been evidenced, and a simple filtering has been proposed. The microwave surface temperatures have also been carefully compared to in situ Ts time series from a collection of more than 20 stations over a large range of environments. Very good agreement is obtained for well‐controlled stations in vegetated environments (down to RMSE of ∼2.5 K for several stations), but the methodology encounter difficulties under cold conditions due to the large variability of snow and ice surface emissivities.
Direct Transfer Printing of Water Hydrolyzable Metals onto Silk Fibroin Substrates through Thermal‐Reflow‐Based Adhesion
Authors: Brenckle Mark A. , Kaplan David L. , Omenetto Fiorenzo G.
Published: May 2016

In recent years, the use of biopolymers as interface materials between inorganic electronics and biological tissues has increased, which has necessitated the integration of micro‐ and nanofabrication techniques with these unconventional materials. This combination has led to devices with intriguing operational characteristics such as so‐called “transient” bioresorbable devices. Here, a method is investigated which leverages the thermal reflow characteristics of non‐beta‐sheet crystallized silk fibroin protein films to transfer print electronic components onto bioresorbable silk substrates. This is accomplished by applying heat and pressure to the interface of the silk and fabricated components, leading to reflow of the silk and transfer of the components from a silicon carrier wafer onto silk. We demonstrate application of this for both traditional (Au) and highly labile transient metals (Mg), over large areas with single micrometer resolution, all while retaining functionality of the transferred components. Additionally, it is shown how control over the reflow characteristics of silk through the process parameters can lead to both water‐stable and water‐soluble device outcomes and retain the efficacy of entrained biological dopants within the silk substrate matrix. Through these means, this method has the potential to improve the number of fabrication options for devices at the biotic/abiotic interface.

Authors: Mujtaba Muhammad , Sargin Idris , Kaya Murat
Published: May 2016

Exploration of biodegradable and renewable composites ingredients is of great importance. Up to now, roots extract of Glycyrrhiza glabra has been used for different medicinal purposes but remaining cellulose‐rich residues have not been evaluated for isolation of any green materials like cellulose. Here in this study, cellulose was successfully isolated from the roots of G. glabra by using conventional cellulose extraction method. The obtained product was characterized using FT‐IR, XRD, and SEM. FT‐IR and XRD analyses confirmed the identity of the product. The crystallinity index of cellulose isolates was calculated from XRD data as 70%. The cellulose content of the roots on dry basis was recorded as 48.5%. Three types of surface morphologies were observed: smooth non‐porous surface, surface with fibril bundles, and porous surface having thin cellulose fibrils. In addition, bovine serum albumin (BSA) adsorption capacity of G. glabra cellulose was determined and compared with that of commercial cellulose. Newly obtained cellulose from the roots of G. glabra exhibited a higher affinity for BSA protein at neutral pH.

Water Oxidation by Ruthenium Complexes Incorporating Multifunctional Bipyridyl Diphosphonate Ligands
Authors: Xie Yan , Shaffer David W. , Lewandowska‐Andralojc Anna , Szalda David J. , Concepcion Javier J.
Published: May 2016

We describe herein the synthesis and characterization of ruthenium complexes with multifunctional bipyridyl diphosphonate ligands as well as initial water oxidation studies. In these complexes, the phosphonate groups provide redox‐potential leveling through charge compensation and σ donation to allow facile access to high oxidation states. These complexes display unique pH‐dependent electrochemistry associated with deprotonation of the phosphonic acid groups. The position of these groups allows them to shuttle protons in and out of the catalytic site and reduce activation barriers. A mechanism for water oxidation by these catalysts is proposed on the basis of experimental results and DFT calculations. The unprecedented attack of water at a neutral six‐coordinate [RuIV] center to yield an anionic seven‐coordinate [RuIV−OH]− intermediate is one of the key steps of a single‐site mechanism in which all species are anionic or neutral. These complexes are among the fastest single‐site catalysts reported to date.
ABS/HIPS blends obtained from WEEE: Influence of processing conditions and composition
Authors: de Souza Adriana Martinelli Catelli , Cucchiara Mayara Gallego , Ereio Adriana Vitório
Published: May 2016

The recycling of acrylonitrile–butadiene–styrene (ABS) and high‐impact polystyrene (HIPS) from postconsumer electronic equipment housing was investigated. A preliminary study of shot size and particle size effects on the mechanical properties of ABS/HIPS (50/50) blends obtained directly via injection molding was conducted. Injection‐molded specimens of ABS/HIPS blends, obtained at different compositions with or without previous extrusion, were subjected to mechanical, thermal, and morphological testing. Preliminary studies showed that a smaller particle size resulted in higher tensile and impact strength, regardless of the shot size used during injection molding. ABS/HIPS blends obtained using previous extrusion presented a slight increase in Young's modulus and a decrease in elongation at break and impact strength. The increase in glass‐transition temperature related to the Polybutadiene (PB) phases of these blends indicated a possible increase in crosslinking structures during extrusion. In addition, these blends showed a coarse and heterogeneous morphology, suggesting that ABS did not completely mix with HIPS. Compared to processing conditions, the blend composition appeared to have a much stronger effect on the mechanical properties. The results obtained suggest the possibility of obtaining ABS/HIPS blends directly via injection molding as long as small ground particles are used. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Published: May 2016

Photochemically mediated controlled/“living” polymerization of methyl methacrylate (MMA) triggered by flavone was studied. The polymerization was performed in ethanol at ambient temperature with CuBr2/Tris(2‐dimethylaminoethyl)amine (Me6TREN) as complex catalyst and ethyl 2‐bromoisobutyrate (EBiB) as initiator. The molar mass of poly(methyl methacrylate) (PMMA) was obtained and exhibited relatively narrow molecular weight distribution (Mw/Mn) which was characterized by gel permeation chromatography (GPC). Chain extension further indicated that the living nature was maintained in the photopolymerization system. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43845.

Authors: Yang Na , Wang Linlin , Finnell Richard H. , Li Zhiwen , Jin Lei , Zhang Le , Cabrera Robert M. , Ye Rongwei , Ren Aiguo
Published: May 2016

Background

After years of periconceptional folic acid supplementation, the prevalence of neural tube defects (NTDs) remains stable following the remarkable reduction observed immediately after the fortification practice. There is accumulating evidence that folate receptor (FR) autoimmunity may play a role in the etiology of folate‐sensitive NTDs.

Methods

From 2011 to 2013, 118 NTD cases and 242 healthy controls were recruited from a population‐based birth defects surveillance system in Northern China. Enzyme‐linked immunosorbent assay was used to measure FR autoantibodies in maternal and cord blood. Logistic regression models were used to estimate the odds ratios (OR) and 95% confidence intervals (95% CI).

Results

Plasma FR autoantibodies levels were significantly elevated in mothers of infants with NTDs compared with mothers of healthy controls. Using the lowest tertile as the referent group, 2.20‐fold (95% CI, 0.71–6.80) and 5.53‐fold increased odds (95% CI, 1.90–16.08) of NTDs were observed for the second and third tertile of immunoglobulin G (IgG), respectively, and the odds of NTDs for each successive tertile of IgM was 0.98 (95% CI, 0.35–2.75) and 3.49 (95% CI, 1.45–8.39), respectively. A dose–response relationship was found between FR autoantibodies levels and risk of NTDs (P< 0.001 for IgG,P= 0.002 for IgM). The same pattern was observed in both subtypes of spina bifida and anencephaly. No significant difference in levels of cord blood FR autoantibodies was observed.

Conclusion

Higher levels of FR autoimmunity in maternal plasma are associated with elevated risk of NTDs in a dose–response manner. Birth Defects Research (Part A) 106:685–695, 2016. © 2016 Wiley Periodicals, Inc.
Quantification of total phosphorothioate in bacterial DNA by a bromoimane‐based fluorescent method
Authors: Xiao Lu , Xiang Yu
Published: May 2016

The discovery of phosphorothioate (PT) modifications in bacterial DNA has challenged our understanding of conserved phosphodiester backbone structure of cellular DNA. This exclusive DNA modification in bacteria is not found in animal cells yet, and its biological function in bacteria is still poorly understood. Quantitative information about the bacterial PT modifications is thus important for the investigation of their possible biological functions. In this study, we have developed a simple fluorescence method for selective quantification of total PTs in bacterial DNA, based on fluorescent labeling of PTs and subsequent release of the labeled fluorophores for absolute quantification. The method was highly selective to PTs and not interfered by the presence of reactive small molecules or proteins. The quantification of PTs in an E. coli DNA sample was successfully achieved using our method and gave a result of about 455 PTs per million DNA nucleotides, while almost no detectable PTs were found in a mammalian calf thymus DNA. With this new method, the content of phosphorothioate in bacterial DNA could be successfully quantified, serving as a simple method suitable for routine use in biological phosphorothioate related studies.
Rapid detection of aflatoxigenic Aspergillus sp. in herbal specimens by a simple, bendable, paper‐based lab‐on‐a‐chip
Authors: Chaumpluk Piyasak , Plubcharoensook Pattra , Prasongsuk Sehanat
Published: May 2016

Postharvest herbal product contamination with mycotoxins and mycotoxin‐producing fungi represents a potentially carcinogenic hazard. Aspergillus flavus is a major cause of this issue. Available mold detection methods are PCR‐based and rely heavily on laboratories; thus, they are unsuitable for on‐site monitoring. In this study, a bendable, paper‐based lab‐on‐a‐chip platform was developed to rapidly detect toxigenic Aspergillus spp. DNA. The 3.0‐4.0 cm2 chip is fabricated using Whatman™ filter paper, fishing line and a simple plastic lamination process and has nucleic acid amplification and signal detection components. The Aspergillus assay specifically amplifies the aflatoxin biosynthesis gene, aflR, using loop‐mediated isothermal amplification (LAMP); hybridization between target DNA and probes on blue silvernanoplates (AgNPls) yields colorimetric results. Positive results are indicated by the detection pad appearing blue due to dispersed blue AgNPls; negative results are indicated by the detection pad appearing colorless or pale yellow due to probe/target DNA hybridization and AgNPls aggregation. Assay completion requires less than 40 min, has a limit of detection (LOD) of 100 aflR copies, and has high specificity (94.47%)and sensitivity (100%). Contamination was identified in 14 of 32 herbal samples tested (43.75%). This work demonstrates the fabrication of a simple, low‐cost, paper‐based lab‐on‐a‐chip platform suitable for rapid‐detection applications.
A new simple morphology‐based risk score is prognostic in stage I/II colon cancers
Authors: Märkl Bruno , Märkl Maximilian , Schaller Tina , Mayr Patrick , Schenkirsch Gerhard , Kriening Bernadette , Anthuber Matthias
Published: May 2016

A portion of stage I/II colon cancers (10–20%) exhibit an adverse clinical course. The administration of adjuvant chemotherapy is recommended only in certain high‐risk situations. However, these risk factors recently failed to predict benefit from adjuvant therapy. We composed a new morphology‐based risk score that includes pT1/2 versus 3/4 stage, vascular or lymphovascular invasion, invasion type according to Jass, tumor budding and paucity (less than two) of lymph nodes larger than 5 mm. The occurrence of each of these factors accounts for one point in the score (Range 0–5). This score was evaluated in a retrospective study that included 301 cases. The overall survival differed significantly between the three groups with median survival times of 103, 90, and 48 months, respectively. Multivariable analysis revealed morphology‐based risk—high risk and low risk—as the sole independent factors for the prediction of death. Morphology‐based risk scoring was superior to microsatellite status and NCCN risk stratification. This method identifies a group of patients that comprises 18% of the stage II cases with an adverse clinical course. Further studies are necessary to confirm its prognostic value and the possible therapeutic consequences.

Permeability, Purity, and Yield in Crystal Beds
Authors: Tang Haihao , Ulrich Joachim
Published: May 2016

The permeability of a phosphoric acid hemihydrate crystal bed as well as the crystal yield and the crystal purity were studied in order to find a suitable range for the operation of a hydraulic wash column. The key parameters were the width of the crystals as a measure of crystal size, the supersaturation, and the stirring speed. The results show that a crystal bed which contains larger crystals gives a higher permeability. A higher supersaturation leads to a higher crystal yield but more impurity inclusions in crystals. A higher stirring speed causes more impurity inclusions in crystals, as well.
