Çalışmanın amacı, Türkiye ve Norveç’in yaşlı sağlık
hizmetleri sistemlerini karşılaştırmalı olarak değerlendirmek ve sonuçlarını
yorumlamaktır. Çalışmada, nitel
araştırma yöntemlerinden tarama yöntemi kullanılmıştır. Türkiye ve Norveç 1000 kişi başına düşen doktor ve hemşire
sayıları açısından değerlendirilirse, 2000 ile 2016 yılları arasında her iki
ülke içinde hekim başına düşen hasta sayısı azalma göstermiş olmasına rağmen
Türkiye’de yıllar itibariyle ciddi bir fark yokken, Norveç’te ciddi bir azalma
görülmektedir. 1000 kişi başına düşen hastane yatak sayılarına ilişkin OECD
verileri değerlendirildiğinde ise Türkiye ve Norveç’de toplam nüfus ve bunun
içindeki yaşlı nüfus oranı yükselmesine karşın, Norveç’te 2008 yılından sonra yatak sayısı
oranları azalma eğilimine girmiş, Türkiye’de ise tam tersi şekilde artışlar
görülmüştür. Toplam huzurevleri sayıları değerlendirildiğinde, Türkiye’nin 2016
yılı itibariyle toplam huzurevi sayısı 367’dir. Norveç’in ise aynı yıl toplam
huzurevi sayısı 955’dir. Türkiye ve Norveç’in toplam GSYİH’den yaşlı bakım
hizmetlerine ayırdığı pay incelendiğinde bu oranlarda ciddi farklılıklar
bulunmaktadır. Türkiye’de toplam 564 milyon lira harcama yapılırken, Norveç’in
ise 74 milyon lira harcama yaptığı tespit edilmiştir. Karşılaştırmalı yaşlı sağlık hizmetleri perspektifinde her iki
ülke karşılaştırıldığında, yaşlı sağlık hizmetlerinin örgütlenmesi, sağlık
harcamaları içerisindeki yaşlılara ayrılan pay, bakımevleri sayıları, sağlık
insan gücü sayıları açısından temel farklılıklar olduğu görülmektedir. Kuşkusuz
iki ülkenin yaşlı sağlık hizmetleri sistemini değerlendirmek için daha kapsamlı
çalışmalara ihtiyaç bulunmaktadır.
RELATIONSHIP BETWEEN PARENTAL OCCUPATION, HOME ENVIRONMENT AND ACADEMIC PERFORMANCE OF PUBLIC SENIOR SECONDARY SCHOOL STUDENTS IN SOKOTO STATE, NIGERIA
Authors: Umar Maimuna Rabo 
Published: May 2019

This paper discussed the relationship between parental background support in relation to occupation, home environment and students’ academic performance. The research design adopted for this study was correlation research design. The study was based on Conflict theory, which sees the purpose of education as a means of maintaining social inequality and preserving the power of those who dominate the society. The study was carried out using questionnaire, achievement test and focus group discussions, the questionnaire was researcher designed and it was based on closed ended questions with options of A,B,C,D,E and F, respectively all the instruments were validated by the supervisory team and the reliability was obtained by pilot testing of questionnaire and test-retest for achievement test and arrived at co-efficient alpha 0.83 and 0.81 respectively. The population was also all the public senior secondary school students in Sokoto state. A total number of twelve public senior secondary schools, with three thousand four hundred and twenty eight (3,428) as the population of SS II students, were purposively selected within the six educational zones to represent the total population. Qualitative data collected were analyzed through thematic analysis by coding and transcription, while the quantitative data were analyzed using Pearson Product Moment Correlation Co-efficient. The major findings of the study were: Parental background support in relation to occupation has relationship with student’s academic performance. Parental background support in relation to home environment has relationship with student’s academic performance. The study recommended that: parents that are found to be of lower socio-economic status who can not provide support for the academic activities of their children, should utilize those community development programmes meant for poverty eradication and skill acquisition, such as National Poverty Eradication Programme (NAPEP), family support programme, agricultural loan scheme and so on, that will provide financial support and job security. It was also recommended that parents should endeavour to provide required academic support at home such as parental commitment and material support. That is to be fully involved in their children academic activities and to provide study facilities at home, which include teaching and learning materials. This will enhance good academic performance.
On Simulating the Proton-irradiation of O2 and H2O Ices Using Astrochemical-type Models, with Implications for Bulk Reactivity
Authors: Shingledecker Christopher N. , Vasyunin Anton , Herbst Eric , Caselli Paola 
Published: May 2019

Abstract
Many current astrochemical models explicitly consider the species that comprise the bulk of interstellar dust grain ice mantles separately from those in the top few monolayers. Bombardment of these ices by ionizing radiation—whether in the form of cosmic rays, stellar winds, or radionuclide emission—represents an astrochemically viable means of driving a rich chemistry even in the bulk of the ice mantle, now supported by a large body of work in laboratory astrophysics. In this study, using an existing rate-equation-based astrochemical code modified to include a method of considering radiation chemistry recently developed by us, we attempted to simulate two such studies in which (a) pure O2 ice at 5 K and (b) pure H2O ice at 16 K and 77 K, were bombarded by keV H+ ions. Our aims were twofold: (1) to test the capability of our newly developed method to replicate the results of ice-irradiation experiments, and (2) to determine how bulk chemistry in such a well-constrained system is best handled using the same gas-grain codes that are used to model the interstellar medium. We found that our modified astrochemical model was able to reproduce both the abundance of O3 in the 5 K pure O2 ice, as well as both the abundance of H2O2 in the 16 K water ice and the previously noted decrease of hydrogen peroxide at higher temperatures. However, these results require the assumption that radicals and other reactive species produced via radiolysis react quickly and non-diffusively with neighbors in the ice.

Published: May 2019

Background Vitamin D (VitD) and calcium (Ca) supplementation attenuates antiretroviral therapy (ART)-associated bone loss, but it is unclear whether this effect is mediated through immunomodulation. Methods In this exploratory analysis of A5280, a 48-week, randomized, double-blind, placebo-controlled study of VitD/Ca supplementation with ART initiation, we characterized lymphocyte phenotypes and receptor activator of nuclear factor kappa-B ligand (RANKL) expression by median fluorescence intensity (MFI) at baseline and 48 weeks. Changes were evaluated within and between treatment groups by Wilcoxon signed rank and rank sum tests, respectively. Spearman correlations estimated relationships between cellular phenotypes and bone mineral density (BMD). Results Of 165 participants enrolled, 138 had samples for cellular phenotypes (64 VitD/Ca, 74 placebo). Markers of CD4, CD8 activation (CD38+HLA-DR+) declined (all P<0.001), but did not differ between arms. There was no decline in either %T-cells (CD4 and CD8) expressing RANKL or expression of RANKL by MFI. CD4 and CD8 activation markers were not correlated with BMD at baseline (r<0.15 and P>0.09 for all), but greater declines in CD4 activation correlated with greater declines in hip and spine BMD in both arms (0.25 ≤r ≤0.37, all P <0.05). A greater decline in CD8 activation was correlated with greater declines in both hip and spine BMD in the placebo arm only (hip r=0.31, P=0.009; spine r=0.25, P=0.035). Conclusions Reductions in T-cell activation are characteristic of ART initiation, but only correlated modestly with bone loss. VitD/Ca supplementation does not appear to mitigate bone loss through modulation of immune activation or expression of RANKL. Trial registration number: NCT01403051.
Les « non-parents ». Ou comment on devient parent d’un enfant absent
Authors: Stettinger Vanessa 
Published: May 2019

L’enfant occupe une place centrale dans la société française d’aujourd’hui. Être parent est un statut recherché, qui amène de la reconnaissance, particulièrement lorsqu’il est, pour l’individu en question, le seul statut socialement valorisant. Qu’advient-il alors des parents dont l’enfant est placé très tôt après la naissance ? À partir d’une recherche ethnographique, cet article vise à montrer comment la mise en place des normes de la parentalité peut produire des « non-parents » et comment ces « non-parents » essayent de déjouer leur sort afin de devenir parents.
The Relationship Among 3 Generic Patient-Reported Outcome Instruments in Patients With Lower Extremity Health Conditions
Authors: Hoch Johanna M. , Lorete Christina , Legner Jamie , Hoch Matthew C. 
Published: May 2019

Context
Generic patient-reported outcome (PRO) instruments are designed to capture health-related quality-of-life outcomes and to determine treatment effectiveness from the patient's perspective. Multiple generic PROs are used in clinical practice, and an investigation of the psychometric properties of these instruments in a high-functioning, physically active population is important for the future use of these instruments.

Objective
To determine the relationship among 3 generic PROs: the modified Disablement in the Physically Active (mDPA) Scale, the Patient-Reported Outcome Measurement Information System Physical Function (PROMIS-PF), and the Short Form 12 (SF-12) in physically active patients seeking treatment for a lower extremity health condition.

Design
Cross-sectional study.

Setting
Athletic training clinical facility, physical therapy clinic.

Patients or Other Participants
One hundred patients seeking rehabilitation services for a lower extremity health condition.

Main Outcome Measure(s)
All patients completed a demographic questionnaire and the 3 generic PROs at 1 time point during their rehabilitation: the mDPA-Total, mDPA-physical summary component (mDPA-PSC), mDPA-mental summary component (mDPA-MSC), the PROMIS-PF, and SF-12 mental component summary (SF-MCS) and physical component summary (SF-PCS). Separate Spearman rank (r) correlations were performed to assess the strength of the relationship among PRO instruments. The floor and ceiling effects were also examined.

Results
A strong relationship was present between the SF-12 PCS and the mDPA-Total (r = −0.65), the mDPA-PSC (r = −0.64), and the PROMIS-PF (r = 0.65). Significant moderate relationships were identified between the mDPA-MSC and the SF-12 PCS (r = −0.43) and MCS (r = −0.53). Weak relationships were noted between the mDPA-Total and SF-12 MCS (r = −0.21) and the SF-12 MCS and mDPA-PSC (r = −0.10) and PROMIS-PF (r = 0.20).

Conclusions
The PROMIS-PF and mDPA had good convergent and divergent validity. Clinicians treating physically active patients should consider these instruments for use in clinical practice. Future researchers should examine additional psychometric properties of these instruments in physically active patients.

Published: May 2019

AbstractThe metastasis to the eye in a patient of carcinoma of the cervix is rare. A case of carcinoma cervix in a 56-year-old female is described who presented with full chamber pseudohypopyon and deep vascularization in inferior quadrant of the cornea in the left eye. Magnetic resonance imaging revealed features suggestive of ocular metastasis in the anterior part of the uveal tract. Diagnosis was confirmed on cytology which showed features of squamous cell carcinoma. A high level of clinical suspicion in advanced cases of malignancies will help in early detection of ocular metastasis with unusual presentations.

Published: May 2019

Abstract
Aims and Objectives: Aim of this study was to assess the clinical usefulness of Acoustic Radiation Force Impulse (ARFI) elastography imaging in differentiating benign and malignant/metastatic superficial nodes.
Methods and Materials: ARFI elastography (Siemens Medical Solutions, Mountain View, CA) using Virtual touch Tissue Imaging (VTI) technique was performed and Shear wave velocity (m/sec) was measured in 85 patients (mean age, 49 years; range, 16–72 years) with 126 lymph nodes (96 axillary, 21 cervical and 9 inguinal nodes) which were biopsied and histo-pathologically correlated.
Results: Of 126 nodes, 71 were benign (64 reactive and 7 koch's) and 55 were malignant (40 metastases and 15 lymphoma). The mean ARFI value of malignant nodes ±SD (4.42 ± 2.60) were significantly higher than the benign nodes (1.76 ± 0.44), with P <0.001. With the use of Receiver Operating Characteristic (ROC) curve, the cut off SWV was estimated to be 2.45m/s with sensitivity of 83.6%, specificity of 91%, and accuracy of 93.7 % while the conventional US based short axis diameter (SAD) measurement with cut off value of 10mm, showed the sensitivity of 62 %, specificity of 87% and accuracy of 87%.
Conclusion: Acoustic radiation force impulse elastography is feasible for superficial lymph nodes and provides quantitative elasticity measurements, which may complement B-mode ultrasound and potentially improve the differentiation of benign and malignant/metastatic lymph nodes.
Tumor motion in lung cancers: An overview of four-dimensional radiotherapy treatment of lung cancers
Authors: Munshi Anusheel , Khataniar Nilaxi , Ganesh Tharmar 
Published: May 2019

AbstractMost modern radiotherapy centers have adopted contouring based treatment. Sparing of the normal structures has been made more achievable than ever before by use of technologies such as Intensity Modulated Radiotherapy (IMRT) and Image guided radiotherapy (IGRT). However, unlike, sites such as brain or head neck, thorax is a site in active motion, mostly contributed by patient's respiratory movement. 4 D radiotherapy, that addresses the issues of motion in thoracic tumours answers this critical question. The present article outlines the scope of need for 4 D radiotherapy and discusses the options available for 4 D treatments of cancer patients.
Management of lung cancer brain metastasis: An overview
Authors: Srivastava Himanshu , Negi Preety , Kingsley Pamela Alice , Sachdeva Jaineet 
Published: May 2019

AbstractWith the improvements in systemic treatment for lung cancer, distant metastasis to sanctuary sites such as brain has become an increasingly more important issue. The management of these patients consists of supportive care and disease-directed treatment. Combined modality treatment (surgical resection or radiosurgery, followed by whole brain radiotherapy) of brain metastases has greatly improved the local control of disease in patients with single lesion, good functional performance status, and controlled extracranial disease as demonstrated in prospective randomized studies. For patients with multiple brain metastases, conventional fractionated whole brain radiotherapy continues to be a standard and efficacious treatment. At present, experience with the use of molecularly targeted tyrosine kinase inhibitors in nonsmall cell lung cancer patients with activating mutations in the epidermal growth factor receptor gene and anaplastic lymphoma kinase gene is growing. However, their effectiveness in patients with brain metastases is not well established. In the arena of targeted therapies, vascular endothelial growth factor pathway inhibitors such as bevacizumab have shown some activity in brain metastases. Further prospective studies are necessary to facilitate selection of patient subpopulation for targeted agents in future studies.
Methionine supplementation improves reproductive performance, antioxidant status, immunity and maternal antibody transmission in breeder Japanese quail under heat stress conditions
Authors: Kalvandi Omid , Sadeghi Amirali , Karimi Ahmad 
Published: May 2019

Abstract. This study was conducted to determine the effects of methionine (Met) supplementation on productive and reproductive performance, immune response and antioxidant status in breeder quails reared under heat stress (HS). A total of 125 breeder quails were divided into five groups. One group was kept in an environmentally controlled room at 22 ∘C and considered as thermoneutral, and four groups were kept at 34 ∘C and fed a basal diet (heat stressed) or a basal diet with Met concentrations 1.15, 1.30 and 1.45 times the quail requirements per NRC (1994) recommendations. HS decreased egg production in birds fed the basal diet (P < 0.05). Higher feed intake (P < 0.05), egg production (P < 0.05), improved feed efficiency (P < 0.05) and Haugh unit and hatchability variables (P < 0.05) occurred in Met supplemented groups. Birds receiving Met under HS had higher maternal serum IgG, egg yolk IgY and offspring serum IgG (mg mL−1). Quails receiving the Met supplementation diets exhibited higher (P < 0.05) plasma levels and liver activity of superoxide dismutase, catalase and glutathione peroxidase as well as lower (P < 0.05) plasma and liver levels of malondialdehyde compared to the HS group fed the basal diet. All breeder quails receiving the Met supplement had lower (P < 0.05) heterophil and H∕L ratios as well as higher (P < 0.05) lymphocytes than quails fed the basal diet under the same stress conditions. Our results suggest that dietary supplementation with Met could improve the performance, immunity and antioxidant status of quails by reducing the negative effects of HS.
Floodwater impact on Galveston Bay phytoplankton taxonomy, pigment composition and photo-physiological state following Hurricane Harvey from field and ocean color (Sentinel-3A OLCI) observations
Authors: Liu Bingqing , D'Sa Eurico J. , Joshi Ishan D. 
Published: May 2019

Abstract. Phytoplankton taxonomy, pigment composition and photo-physiological state
were studied in Galveston Bay (GB), Texas (USA), following the extreme
flooding associated with Hurricane Harvey (25–29 August 2017) using field
and satellite ocean color observations. The percentage of chlorophyll a
(Chl a) in different phytoplankton groups was determined from a
semi-analytical IOP (inherent optical property) inversion algorithm. The IOP
inversion algorithm revealed the dominance of freshwater species (diatom,
cyanobacteria and green algae) in the bay following the hurricane passage
(29 September 2017) under low salinity conditions associated with the
discharge of floodwaters into GB. Two months after the hurricane
(29–30 October 2017), under more seasonal salinity conditions, the
phytoplankton community transitioned to an increase in small-sized groups
such as haptophytes and prochlorophytes. Sentinel-3A Ocean and Land Colour Instrument (OLCI)-derived Chl a
obtained using a red ∕ NIR (near-infrared) band ratio algorithm for the turbid estuarine
waters was highly correlated (R2>0.90) to the (high-performance liquid
chromatography) HPLC-derived
Chl a. Long-term observations of OLCI-derived Chl a
(August 2016–December 2017) in GB revealed that hurricane-induced Chl a
declined to background mean state in late October 2017. A non-negative least
squares (NNLS) inversion model was then applied to OLCI-derived Chl a maps
of GB to investigate spatiotemporal variations of phytoplankton diagnostic
pigments pre- and post-hurricane; results appeared consistent with extracted
phytoplankton taxonomic composition derived from the IOP inversion algorithm
and microplankton pictures obtained from an Imaging FlowCytobot (IFCB).
OLCI-derived diagnostic pigment distributions also exhibited good agreement
with HPLC measurements during both surveys, with R2 ranging from 0.40
for diatoxanthin to 0.96 for Chl a. Environmental factors (e.g.,
floodwaters) combined with phytoplankton taxonomy also strongly modulated
phytoplankton physiology in the bay as indicated by measurements of
photosynthetic parameters with a fluorescence induction and relaxation (FIRe)
system. Phytoplankton in well-mixed waters (mid-bay area) exhibited maximum
PSII photochemical efficiency (Fv∕Fm) and a low effective absorption cross
section (σPSII), while the areas adjacent to the shelf
(likely nutrient-limited) showed low Fv∕Fm and elevated
σPSII values. Overall, the approach using field and
ocean color data combined with inversion models allowed, for the first time,
an assessment of phytoplankton response to a large hurricane-related
floodwater perturbation in a turbid estuarine environment based on its
taxonomy, pigment composition and physiological state.
