Published: May 2019

Introduction:
Displaced supracondylar humerus fractures (SCFs) are common pediatric injuries, typically treated by closed reduction and percutaneous pinning (CRPP). Radiographs are obtained at pin removal and subsequently to evaluate fracture healing. We evaluated the utility of radiographs obtained after pin removal in pediatric SCF management.

Methods:
A retrospective cohort study of children aged 2 to 11 years with SCF requiring CRPP at a single institution from January 2007 to July 2017 was conducted. Radiographs were taken at pin removal and minimum 3 weeks later. Demographic and treatment data were collected via chart review. Radiographic measures were Baumann and lateral humeral-capitellar angles, anterior humeral line alignment, and number of cortices with callus. The McNemar-Bowker test analyzed anterior humeral line alignment and cortices with callus. The paired t-test analyzed Baumann and lateral humeral-capitellar angles.

Results:
One hundred patients were included (47 males and 53 females, mean 5.7 years). The mean time to pin removal was 23.8 days, and the median clinical and radiographic follow-up periods were 109.0 and 52.2 days, respectively. Fracture patterns were extension type II (21%), III (73%), IV (1%), flexion (4%), and varus (1%). No patients' fracture management changed in the acute or long-term postoperative period because of findings on post-pin removal (PPR) radiographs. Fewer cortices with callus were seen at pin removal versus PPR (<0.001). At pin removal, no differences were found in the Baumann angle (75.8 ± 5.0 versus 74.6 ± 5.9; P = 0.053), lateral humeral-capitellar angles (30.7 ± 12.5 versus 31.6 ± 1.3; P = 0.165), or anterior humeral line alignment (P = 0.261).

Discussion:
No patients' fracture management was modified because of findings evident on PPR radiographs. The number of cortices with callus was the only radiographic measure to differ over time, as is anticipated with routine healing. Elbow radiographic alignment measures did not differ in the interval between radiographs. Therefore, PPR radiographs may not provide clinical utility in the absence of other clinical findings.

Demographic, clinical and treatment characteristics of patients with Kaposi’s sarcoma: A single-center study
Authors: SALMAN Andac , OZGEN Zuleyha 
Published: May 2019

Objective:
The clinical,
demographic and treatment characteristics of patients with Kaposi’s sarcoma
(KS) are not well-defined. There is lack of consensus on treatment modalities.
Thus, we aimed to define demographic, clinical characteristics and treatment
outcomes in our cohort of patients with KS.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Patients and Methods: A retrospective cohort study was
done and all patients who were followed up in our specialized cutaneous tumors
outpatient clinic with a diagnosis of KS between 2006 and 2018 were included in
the study.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Results: A total of 25 patients were included
in the study. The mean age of the patients was 66 and 80% were male. The most
common form of KS was classic type (80%). During a mean follow-up of 43 months,
the most frequently administered treatments were cryotherapy, interferons,
radiotherapy, topical imiquimod and topical timolol. Overall a complete
response was observed in 9 (36%) patients.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Conclusion: The clinical and demographic
characteristics of our cohort match those observed in existing literature. We
think that the use of local treatments such as cryotherapy, topical imiquimod
should be used more frequently in patients with limited disease. Considering
the efficacy of timolol in other vascular tumors, future prospective studies
investigating the effects of timolol in KS are highly warranted.

Abstract: Evaluation of a speech therapy in patients with Alzheimer's disease under cholinergic treatment: A pilot study. The intervention on Alzheimer's disease (AD) has shown that pharmacological treatments with acetylcholinesterase inhibitors are highly beneficial. There is not much evidence if other treatments are effective, because it is difficult to find patients who are not medicated. In the present study a logopedic intervention in patients with AD in the mild phase, with and without pharmacological treatment, was verified. The results show that logopedic intervention slows the deterioration of the disease. The combination of logopedic intervention and pharmacological therapy is confirmed as the therapeutic option that most benefits the patient, while patients who only received one of the treatments show a more pronounced cognitive deterioration. The conclusions indicate that the pharmacological approach is necessary but insufficient, and that a logopedic intervention may be an adequate and effective complement in AD.Keywords: Alzheimer disease; Speech therapy; Acetylcholinesterase inhibitors. Resumen: Al intervenir en pacientes con la enfermedad de Alzheimer (EA) se ha comprobado que los tratamientos farmacológicos con inhibidores de acetilcolinesterasa resultan altamente beneficiosos, pero existen pocas evidencias sobre la efectividad de otros tratamientos debido a que es difícil encontrar pacientes que no estén medicados. En el presente estudio piloto se comprueba la efectividad de una intervención logopédica en enfermos con EA en fase leve, con y sin tratamiento farmacológico. Los resultados muestran que la intervención logopédica frena el deterioro de la enfermedad. La combinación de intervención logopédica y terapia farmacológica es la opción terapéutica que más beneficios reporta al paciente, mientras que los enfermos que sólo recibieron uno de los tratamientos muestran un deterioro cognitivo más pronunciado. Las conclusiones indican que la aproximación farmacológica es necesaria pero insuficiente, y que una intervención logopédica puede ser un complemento adecuado y eficaz de la EA.Palabras clave: Enfermedad de Alzheimer; Intervención logopédica; Inhibidores de acetilcolinesterasa.

Abstract: Mindfulness and social cognition skills in the prediction of affective symptomatology in schizophrenia, obsessive-compulsive disorder and nonclinical participants. The aim of the study was to investigate significant predictors of affective symptomatology in schizophrenia, obsessive-compulsive disorder and healthy controls. The sample was of 91 participants who completed the following instruments: the Eye Test (emotional recognition), the Hinting Task (theory of mind), the Ambiguous Intentions and Hostility Questionnaire(AIHQ; attributional style), Interpersonal Reactivity Index (IRI; empathy), the Mindful Attention Awareness Scale (MAAS; mindfulness trait), the Five Facet Mindfulness Questionnaire-Short Form(FFMQ-SF), and the Hospital Anxiety and Depression Scale(HADS). Significant predictors of affective symptomatology were: mindfulness (dispositional or trait mindfulness, nonreactivity and nonjudgment), and social cognition (SC) (attributional style and theory of mind). Mediation analysis showed that theory of mind was the only significant mediator of affective symptomatology. This paper shows the role of mindfulness and SC skills in the prediction of affective symptomatology.Keywords: mindfulness, social cognition, theory of mind, affective symptomatology, schizophrenia, obsessive-compulsive disorder.Resumen:El objetivo del estudio fue investigar predictores significativos de sintomatología afectiva en Esquizofrenia (EZ), trastorno obsesivo compulsivo (TOC) y controles no clínicos.

Published: May 2019

Objectives: This study aimed to evaluate the effect of heating on the fluoride releasing of glass ionomer cement (GIC) combined with 5% CPC (experimental) or not (control). Materials and Methods: Twenty (n=5; each group) GIC samples were prepared with or without 5% CPC powder. The samples were prepared as non-heating (NH) (n=10) or by heating (H) for 60s (H) (n=10) with a Light Emitting Diode. Flouride releasing pattern was obtained at days 1, 7, 15 and 30. Repeated measurements of two-way ANOVA and Fisher’s LSD test was used for comparisons (p&lt;0.05).Results: Interaction (groups x heating x time) effects were obtained (p&lt;0.001). There was no significant difference in fluoride release from the NH control and experimental groups on days 1, 7 and 15, but there was a significant release in the experimental group at 30 days (p = 0.01). Significantly higher values were obtained in H procedures at days 1 (p=0.026), 7 (p=0.001), 15 (p=0.005) and 30 (p=0.028) for control group compared to the experimental. Significantly increased values were obtained from days 1 up to 30 in NH and H procedures for both groups (p&lt;0.001). Conclusions: Heating of both control and experimental groups showed increased fluoride releasing pattern. The fluoride releasing of 60s heating of GIC containing 5% CPC could have acceptable increased values up to 30 days. The increased fluoride releasing pattern after heating procedure seems to be promising for antibacterial GIC combinations.

I am pleased to inform
you that I have chosen this article by Kurt et al.1 as Editor’s
Choice for the second issue of 2019.

Glass ionomer
cements (GICs) are widely used in dental procedures and pediatric
dentistry. One of the most important advantages of GIC is the property of
fluoride release which leads to increase ambient pH and prevent acidity by
inhibiting the carbohydrate metabolism of the surrounding bacteria, resulting
in the prevention of dental caries in future.

This
article shows that the effect of heat application leads an
increased F− releasing pattern on fluoride release from antibacterial agent added The
increased F− releasing pattern after the heating is believed to be
promising for antibacterial GIC combinations.

Aims: The present research seeks to assess the genetic diversity of African yam bean accessions in Nigeria using seed protein marker; geared towards its genetic improvement and conservation. Introduction: African yam bean is an “Orphan Crop” highly nutritious and has been listed to be among the underutilized legumes despite its immense nutritional advantages in human diets. African yam bean has been reported as a good source of essential amino acids including cysteine, lysine, methionine, phenylalanine and Proline.
Study Design: Fifteen (15) accessions of African yam bean were collected from the International Institute for Tropical Agriculture (IITA), Ibadan and 25 local accessions were collected from different parts of Nigeria including Enugu.
Results: This study evaluated the genetic diversity on forty (40) accessions of African yam bean (Sphenostylis stenocarpa) obtained from IITA germplasm bank and other parts of Nigeria. In this study, the genetic differences among the accessions were detected by the presence or absence of bands, which could be used as a basis for variation among accessions. The results from this present study revealed high polymorphism (≈93%), indicating high intra-specific genetic variation with potential linkage to traits desired by breeders.
Conclusion: The study demonstrated that seed storage protein using SDS-PAGE is an important tool for genetic diversity study in African yam bean, providing baseline information. This baseline information will be useful in further molecular studies geared toward efficient breeding and conservation strategies for this crop.

In this area of agricultural transformation by the government of Nigeria, every opportunity in order to achieve food security should not be ignored. Most studies on soil characteristics had centered on the suitability of the soil for agricultural production and it is observed that any soil that does not support crop production refers to as poor and unproductive. Achieving efficient production and high yield requires adequate knowledge of the soil and climatic conditions that are favorable to the crops. The study was conducted to investigates physico-chemical and hydraulic properties of forest soils in southwestern, Nigeria in latitude 7o5’3’’N and 7o 21’57.6’N and longitude 5o 10’31’’E and 5o56’6.3’’E. The soil samples were randomly taken from four (4) forest locations in Ondo State, Nigeria. The soils were taken at different depths (0-15 cm, 15-30 cm, and 30-45 cm) and the samples were taken to the laboratory in order to determine their pH, electrical conductivity, exchangeable cations, and texture. The results of the soil test were then subjected to appropriate statistical analyses. Results show that sandy soil had the highest percentage in the forest at kajola oju-irin (70%). The bulk density is high in Ijare with 1.6 g/cm3 which could allow easy penetration of water and nutrient. Also, the soil pH, electrical conductivity and exchangeable cations range from 4.65 to 6.99,78.28 to 89.20 mS/cm and 0.40 cmol/kg to 2.60 cmol/kg respectively. The soils are described as light and falls under sandy loam soil. This study provides information on the suitability of the soils in the forest areas in south west Nigeria.

ObjectivePrimary cardiac involvement is presumed to account for a substantial part of disease‐related mortality in systemic sclerosis (SSc). Still, there are knowledge gaps on the evolution and total burden of systolic dysfunction in SSc. Here we evaluated prospective left ventricular (LV) and right ventricular (RV) systolic function in an unselected SSc cohort and assessed the burden of systolic dysfunction on mortality.MethodsFrom the Oslo University Hospital cohort, 277 SSc patients were included from 2003‐2016 and compared with healthy controls. Serial echocardiographies were reevaluated in order to detect change in systolic function. Right heart catheterization was performed on patients suspected of pulmonary hypertension. Descriptive and regression analyses were conducted.ResultsAt baseline, LV systolic dysfunction by ejection fraction less than 50%, or a global longitudinal strain greater than −17.0%, was found in 12% and 24%, respectively. RV systolic dysfunction measured by tricuspid annular plane systolic excursion (TAPSE) less than 17 mm was evident in 10%. Follow‐up echocardiography was performed after a median of 3.3 years (interquartile range [IQR] 1.5‐5.6). At follow‐up, LV systolic function remained stable, whereas RV function evaluated by TAPSE deteriorated (mean 23.1 to 21.7 mm, P = 0.005) equaling a 15% prevalence of RV systolic dysfunction. RV systolic function predicted mortality in multivariable models (hazard ratio 0.41, 95% confidence interval [CI] 0.19‐0.90, P value 0.027), whereas LV systolic function lost predictive significance when adjusted for TAPSE.ConclusionIn this unselected and prospective study, systolic dysfunction of the LV and RV was a frequent complication of SSc. LV systolic function remained stable across the observation period, whereas RV function deteriorated and predicted mortality.

AbstractIonic transition‐metal complexes based on silver(I) metal core (Ag‐iTMCs) represent an appealing alternative to other iTMCs in solid‐state lighting owing to (i) their low cost and well‐known synthesis, (ii) the tunable bandgap, and (iii) the highly efficient photoluminescence. However, their electroluminescence behavior is barely studied. Herein, the archetypal green‐emitting Ag‐iTMCs, namely [Ag(4,4′‐dimethoxy‐2,2′‐bipyridine)(Xantphos)]X (X = BF4, PF6, and ClO4), are thoughtfully investigated, revealing their electroluminescent features in light‐emitting electrochemical cells (LECs). Despite optimizing device fabrication and operation, luminance of 40 cd m−2, efficacy of 0.2 cd A−1, and a very poor stability of 30 s are achieved. This outcome encourages the comprehensive study of the degradation mechanism combining electrochemical impedance spectroscopy, X‐ray diffraction, and cyclic voltammetry techniques. These results point out the irreversible formation of silver nanoclusters under operation strongly limiting the device performance. As such, LECs are further optimized by (i) changing the counterions (PF6− and ClO4−) and (ii) decoupling electron injection and exciton formation using a double‐layered architecture. The synergy of both approaches leads to a broad exciplex‐like whitish electroluminescence emission (x/y CIE of 0.40/0.44 and color rendering index of 85) with an outstanding improved stability of ≈4 orders of magnitude (>80 h) without losing brightness (35 cd m−2).

Published: May 2019

AbstractHighly efficient and stable blue phosphorescent organic light‐emitting diodes are achieved by employing a step‐wise graded doping of platinum(II) 9‐(pyridin‐2‐yl)‐2‐(9‐(pyridin‐2‐yl)‐9H‐carbazol‐2‐yloxy)‐9H‐carbazole (PtNON) in a device setting. A device employing PtNON demonstrates a high peak external quantum efficiency (EQE) of 17.4% with an estimated LT70 lifetime of over 1330 h at a brightness of 1000 cd m−2. PtNON is then investigated as a “triplet sensitizer” in an alternating donor–acceptor doped emissive layer to further improve the device emission color purity by carefully managing an efficient Förster resonant energy transfer from PtNON to 2,5,8,11‐tetra‐tert‐butylperylene as a selected acceptor material. Thus, such OLED devices demonstrate an EQE of 16.9% with color coordinates of (0.16, 0.25) and an estimated luminance (LT70) lifetime of 628 h at a high brightness of 1000 cd m−2.

AbstractNanoscale manipulation of magnetic fields has been a long‐term pursuit in plasmonics and metamaterials, as it can enable a range of appealing optical properties, such as high‐sensitivity circular dichroism, directional scattering, and low‐refractive‐index materials. Inspired by the natural magnetism of aromatic molecules, the cyclic ring cluster of plasmonic nanoparticles (NPs) has been suggested as a promising architecture with induced unnatural magnetism, especially at visible frequencies. However, it remains challenging to assemble plasmonic NPs into complex networks exhibiting strong visible magnetism. Here, a DNA‐origami‐based strategy is introduced to realize molecular self‐assembly of NPs forming complex magnetic architectures, exhibiting emergent properties including anti‐ferromagnetism, purely magnetic‐based Fano resonances, and magnetic surface plasmon polaritons. The basic building block, a gold NP (AuNP) ring consisting of six AuNP seeds, is arranged on a DNA origami frame with nanometer precision. The subsequent hierarchical assembly of the AuNP rings leads to the formation of higher‐order networks of clusters and polymeric chains. Strong emergent plasmonic properties are induced by in situ growth of silver upon the AuNP seeds. This work may facilitate the development of a tunable and scalable DNA‐based strategy for the assembly of optical magnetic circuitry, as well as plasmonic metamaterials with high fidelity.
