Abstract
Background

Previous clinical studies have reported associations between the acromion index (AI), lateral acromion angle (LAA), and critical shoulder angle (CSA) and the occurrence of rotator cuff tears. The objective of this study was to analyze the correlations of these different anatomic parameters.

Materials and Methods

Healthy Chinese participants ( n = 66) and Chinese patients with rotator cuff tears ( n = 70) identified between January 2014 and October 2015 were included in this study. Standardized true anteroposterior radiographs were used to measure the AI, LAA, and CSA in each study participant.

Results

The mean AI was significantly larger (0.71 standard deviation [SD], 0.05; range 0.58–0.89 vs. 0.64 SD, 0.06; range 0.55–0.78; P < 0.001), the mean LAA was significantly smaller (77.0° SD, 5.73; range 61.0°–94.5° vs. 82.0° SD, 7.33; range 67.6°–98.3°; P < 0.001), and the mean CSA was significantly larger (36.1° SD, 5.29; range 21.3°–42.4° vs. 31.6° SD, 5.29; range 21.4°–45.8°; P < 0.001) in patients with full-thickness rotator cuff tears compared with healthy participants.

Conclusions

There were a negative linear relationship between the AI and LAA (rotator cuff tears: R = −0.759, P < 0.01; healthy participants: R = −0.813, P < 0.01) and a positive linear relationship between the AI and CSA (rotator cuff tears: R = 0.854, P < 0.01; healthy participants: R = 0.912, P < 0.01) in patients with rotator cuff tear and healthy participants; we termed this phenomenon “The Acromion Rule.” The AI, LAA, and CSA are independent predictors of rotator cuff tears in a Chinese population.

Published: February 2020

Abstract
Background Falls efficacy is a widely-studied latent construct in community-dwelling older adults. Various self-reported instruments have been used to measure falls efficacy. Empirical evidence is needed to justify the selection of a specific instrument to measure the intended construct. Methods To summarize evidence on the development, content validity and structural validity of instruments measuring falls efficacy in community-dwelling older adults using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) checklist. MEDLINE, Web of Science, PsychINFO, SCOPUS, CINAHL were searched (May 2019). Records on the development of instruments and studies assessing content validity or structural validity of falls efficacy related scales were included. COSMIN methodology was used to guide the review of eligible studies and assessed their methodological quality. Evidence of content validity: relevance, comprehensiveness and comprehensibility and unidimensionality for structural validity were synthesized. A modified GRADE approach was applied to evidence synthesis. Results 35 studies, which had 18 instruments identified, were included in the review. High-quality evidence showed that the modified Falls Efficacy Scale (FES)–13 items (mFES-13) has sufficient relevance but insufficient comprehensiveness for measuring falls efficacy. Moderate quality evidence supported the FES-10 has sufficient relevance and mFES-14 has sufficient comprehensibility. Activities-specific Balance Confidence (ABC) Scale–Simplified (ABC-15) has sufficient relevance to measuring balance confidence supported by moderate-quality evidence. Low to very low quality evidence underpinned the content validity of other instruments. High-quality evidence supported sufficient unidimensionality for eight instruments (FES-10, mFES-14, ABC-6, ABC-15, ABC-16, Iconographical FES (Icon-FES), FES–International (FES-I) and Perceived Ability to Prevent and Manage Fall Risks (PAPMFR)). Conclusion Content validity of instruments to measure falls efficacy is understudied. Structural validity is sufficient for a number of widely-used instruments. Measuring balance confidence is a subset of falls efficacy. Further work is needed to investigate a broader construct of falls efficacy.

Abstract
BACKGROUND: Psoriasis is a chronic, inflammatory and multifactorial dermatosis that impairs quality of life (QoL). Health-related QoL has become an important element in medical decision making along with the effectiveness and the harmlessness of the treatments.OBJECTIVE: To assess the impact of psoriasis in the QoL of patients with psoriasis by using the DLQI scales.METHODS: A cross-sectional study, during ten months, was conducted in the Department of Dermatology of the University Hospital Joseph Raseta Befelatanana Antananarivo Madagascar including patients more than 15 years-old with moderate to severe psoriasis. The severity of psoriasis was assessed using the “Psoriasis Area and Severity Index (PASI)”. QoL of patients with psoriasis was evaluated by using the DLQI scales.RESULTS: 80 patients were included, their mean age was 36,52 years and the male to female was 1,5:1. The mean DLQI score was 13,85. Symptoms, feelings and psychic were the most altered dimensions. QoL was impaired in young patients, single, having medium level education. Even though patients with disease duration more than 5 years had higher DLQI score than other patients, the difference was not statistically significant (p=0,36). Furthermore, clinical presentation of psoriasis didn’t influence patient’s QoL (p=0,73). Patients with nail involvement had QoL impaired but the difference with another localization was not statistically significant (p=0,2).The quality of life was influenced by body area involved. The higher the body surface area involved, the more QoL is impaired (p=0,002). Furthermore, the higher the PASI, the more QoL is altered (p=0,002).CONCLUSION: Psoriasis has a negative impact in the quality of life in Malagasy patients with psoriasis, especially in younger and single patients. Worse quality of life is correlated to severity of psoriasis.
Distinctive nursing practices in working with mothers to care for hospitalised children at a district hospital in KwaZulu-Natal, South Africa: a descriptive observational study

Published: February 2020

Abstract
Background: The presence of family members and their active involvement in caring for hospitalised children is an established practice in many African paediatric settings, with family members often regarded as a resource. This aspect of African paediatric nursing practice lacks formal expression or a clear conceptual basis, and difficulties arise when applying concepts of family involvement originating from the higher-resourced and culturally distinct practice environments of the global North. The aim of this study was to articulate a nurse-led practice innovation intended to facilitate family involvement in the care of hospitalised children, observed in a paediatric inpatient ward in a district hospital in rural KwaZulu-Natal, South Africa.Methods: A qualitative case study design was used. Data collection included visual research methods (graphic facilitation, sociograms and photo-elicitation) as well as a focus group, interviews and practice observation. Activities associated with 20 nurses and 22 mother-child dyads were observed. Data were subjected to content analysis, with Standards for Reporting Qualitative Research (SRQR) applied. Results: Findings relate to six aspects of practice, categorised thematically as: preserving the mother-child pair; enabling continuous presence; psychological support and empathy; sharing knowledge; mothers as a resource; and belief and trust. Conclusion: The nursing practices and organisational policies observed in this setting relating to the facilitation of continuous maternal presence represent a distinctive nursing practice innovation. This deliberate practice contrasts with models of care provision which originate in the global North, such as Family Centred Care, and contrasts with informal practices in local African settings which tolerate the presence of mothers in other settings, as well as local institutional policies which limit mothers’ presence to varying extents.

Abstract
Background:Nasopharyngeal cancer is commonly associated with EBV infection, especially the undifferentiated non keratinized histology. EBV DNA quantification through nasopharyngeal brushing was previously reported not related with disease stages. This study aimed to reinvestigate relationship of EBV viral load in tumor tissue with tumor extensiveness by more accurate EBV DNA quantification through microscopically confirmed tumor cells from nasopharyngeal biopsy. Method:The specimens for EBV DNA quantification was derived from histopathology slides which was pre-treated following QIAsymphony® SP Protocol for tissue DNA extraction. Then the extracted DNA underwent real time Polymerase Chain Reaction (RT-PCR) using artus® EBV RG PCR Kit for EBV DNA quantification. The tumor volume was determined by delineating gross tumor based on 3D imaging of the patient’s nasopharynx.Result:Twenty-four subjects were included in this study. All subjects were stage III and above with more males (75%) than females. EBV viral load in tumor cells were found to have no correlation with tumor volume both in local and nodal. The median local tumor volume was 81.3 cm3 ± 80 cm3. The median EBV viral load in tumor cells was 95,644.8 copies/100ng of DNA ± 224,758.4 copies/100ng of DNA. The median nodal or regional tumor volume was 35.7 cm3 ± 73.63 cm3.Conclusion:EBV viral load from tumor cells from nasopharyngeal biopsy has no relationship with tumor extensiveness in nasopharyngeal cancer. The presence and number of EBV in tumor cells did not translate into larger or smaller tumor. The EBV viral proteins and RNAs were perhaps more likely to confer some prognostic information due to the facts that those molecules were related with carcinogenesis.

Published: February 2020

Abstract
Background Estradiol, a predominant female sex hormone, is not only related to reproductive function but also to the ocular disorders. The purpose of this study was to investigate the association between estradiol and idiopathic macular hole (IMH) in postmenopausal women. Method This study included 30 postmenopausal patients with IMH for the study group and 32 postmenopausal patients with uncomplicated primary retinal detachment for the control group. The two groups were compared of serum and vitreous estradiol levels, and clinical variables. Results There was no statistically significant difference in age between the two groups (P = 0.071). Estradiol in the serum was lower in subjects with idiopathic macular hole than that in control participants (18.9 ± 4.5 vs. 43.7 ± 6.1 pg/mL, P < 0.001). Estradiol in the vitreous body was higher in the study group than in the controls (121.2 ± 41.6 vs. 79.8 ± 10.1 pg/mL, P < 0.001). There was a significant correlation between serum estradiol and vitreous estradiol (r = - 0.440, P < 0.001). Conclusion Lower estradiol levels in the serum and higher estradiol levels in the vitreous body after menopause are associated with the occurrence of idiopathic macular hole in postmenopausal women.

Published: February 2020

Abstract
Objective: According to the WHO novel coronavirus (2019-nCoV) situation report 16, as at 5 th February 2020, there was a total of 24363 confirmed 2019-nCoV cases in China. That consisted of the world 491. The specific objective of this study was to estimate, using human capital approach, the fiscal value of human lives lost due to 2019-nCoV in China as at 5 th February 2020. Results: The deaths from 2019-nCoV had a discounted (at 3%) total fiscal value of Int$174,895,675. Out of which, 63.2% was borne by people aged 25-49 years, 27.8% by people aged 50-64 years, and 9.0% by people aged 65 years and above. Average fiscal value per death was Int$ 356,203. Re-estimation of the economic model alternately with 5% and 10 discount rates led to a reduction in the expected total fiscal value by 21.3% and 50.4%, respectively. Furthermore, re-estimation of the economic model using the Japanese female life expectancy of 87.1 years (highest in the world), instead of the national life expectancy of 76.4 years, increased the total fiscal value by Int$ 43,415,455 (24.8%).

Abstract
Phosphonates are widely used in various industries. It is desirable to remove them before discharging phosphonate-containing wastewater. This study describes a large number of batch experiments with adsorbents that are likely suitable for the removal of phosphonates. For this, adsorption isotherms for four different granular ferric hydroxide (GFH) adsorbents were determined at different pH values in order to identify the best performing material. Additionally, the influence of temperature was studied for this GFH. A maximum loading for nitrilotrimethylphosphonic acid (NTMP) was found to be ∼12 mg P/g with an initial concentration of 1 mg/L NTMP-P and a contact time of 7 days at room temperature. Then, the adsorption of six different phosphonates was investigated as a function of pH. It was shown that GFH could be used to remove all investigated phosphonates from water and, with an increasing pH, the adsorption capacity decreased for all six phosphonates. Finally, five adsorption–desorption cycles were carried out to check the suitability of the material for multiple re-use. Even after five cycles, the adsorption process still performed well.

Published: February 2020

13 February 2019, Dmitry Medvedev, Chairman of the Government of the Russian Federation, approved the “Spatial Development Strategy of the Russian Federation for the Period up to 2025”. This document is undoubtedly a significant milestone in the formation of the state regional policy. However, its practical significance caused reasonable doubts among experts. First of all, attention was drawn to the basic term of “spatial development”. How does it differ from the “regional development policy”, the principles main goals and mechanisms of which have not yet defined? May the substitution of the concepts be a way of avoiding this fundamentally important task? They caused questions and uncertainty of the role of regions in the Russian Federation in ensuring the spatial development of the economy. Their place in this process is not specified. The Strategy actually did not take into account the differences of the Russian regions in terms of their socio-economic development and innovative potential. The overall conclusion of a significant part of the expert community was reduced to the need for: substantial refinement of the Strategy; concretization of its basic provisions; developing mechanisms to enhance the role the Russian regions in this process, taking into account differences in their levels of development and socio-economic potential. An attempt to demonstrate the significance of these differences was undertaken in this study, the results of which are summarized in this article.

Published: February 2020

Background:
Despite lutein is unstable in light, heat, and oxygen, it is a good quencher of
singlet oxygen. The present study evaluated the stability of lutein (92% of purity) in Lipid-core Nanocapsules
(Lutein-LNC) prepared through interfacial deposition of preformed polymer, during photosensitization
(5-25°C) and heating (70-90°C).

Methods:
The Lutein-LNC was characterized and presented a polydispersity index of 0.11, an average
diameter of 191 nm (dynamic light scattering), zeta potential of -9.14 mV and entrapment efficiency of
100%.

Results and Discussion:
During photosensitization and heating, Lutein-LNC exhibited activation Energy
(Ea) of 24.67 kcal/mol and 9.96 kcal/mol, respectively, and these values of Lutein-LNC were
higher than free lutein values, reported in other studies for both experiments.

Conclusion:
The results obtained in this study suggested that nanotechnology can improve the stability
of lutein for future applications in the food industry.
Determination of Epsilon Aminocaproic Acid Based on Charge Transfer Complexation with p-Nitrophenlol by Spectrophotometry
Authors: Tian Fang , Li Sheng-Yun 
Published: February 2020

Introduction:
Spectrophotometry was investigated for the determination of epsilon aminocaproic
acid (EACA) with p-nitrophenol (PNP). The method was based on Charge Transfer (CT)
complexation of this drug as n-electron donor with π-acceptor PNP.

Methods:
The experiment indicated that CT complexation was carried out at room temperature for 10
minutes in dimethyl sulfoxide solvent. The spectrum obtained for EACA/PNP system showed the maximum
absorption band at a wavelength of 425 nm. The stoichiometry of the CT complex was found to
be a 1:1 ratio by Job’s method between the donor and the acceptor. Different variables affecting the
complexation were carefully studied and optimized. At the optimum reaction conditions, Beer’s law
was obeyed in a concentration limit of 1～6 μg mL-1. The relative standard deviation was less than
2.9%. The apparent molar absorptivity was determined to be 1.86×104 L mol-1cm-1 at 425 nm. The CT
complexation was also confirmed by both FTIR and 1H NMR measurements.

Results:
The thermodynamic properties and reaction mechanism of the CT complexation have been
discussed.

Conclusion:
The developed method could be applied successfully for the determination of the studied
compound in its pharmaceutical dosage forms with good precision and accuracy compared to the official
method comprising t- and F-tests.
Implementation of Orthogonal Codes Using MZI
Authors: Samanta Supriti , Maity Goutam K. , Mukhopadhyay Subhadipta 
Published: February 2020

Background:
In Code Division Multiple Access (CDMA)/Multi-Carrier CDMA (MCCDMA),
Walsh-Hadamard codes are widely used for its orthogonal characteristics, and hence, it leads
to good contextual connection property. These orthogonal codes are important because of their various
significant applications.

Objective:
To use the Mach–Zehnder Interferometer (MZI) for all-optical Walsh-Hadamard codes is
implemented in this present paper.

Method:
The Mach–Zehnder Interferometer (MZI) is considered for the Tree architecture of Semiconductor
Optical Amplifier (SOA). The second-ordered Hadamard and the inverse Hadamard matrix
are constructed using SOA-MZIs. Higher-order Hadamard matrix (H4) formed by the process of
Kronecker product with lower-order Hadamard matrix (H2) is also analyzed and constructed.

Results:
To experimentally get the result from these schemes, some design issues e,g Time delay, nonlinear
phase modulation, extinction ratio, and synchronization of signals are the important issues. Lasers
of wavelength 1552 nm and 1534 nm can be used as input and control signals, respectively. As
the whole system is digital, intensity losses due to couplers in the interconnecting stage may not create
many problems in producing the desired optical bits at the output. The simulation results were obtained
by Matlab-9. Here, Hadamard H2 (2×2) matrix output beam intensity (I ≈ 108 w.m-2) for different
values of inputs.

Conclusion:
Implementation of Walsh-Hadamard codes using MZI is explored in this paper, and experimental
results show the better performance of the proposed scheme compared to recently reported
methods using electronic circuits regarding the issues of versatility, reconfigurability, and compactness.
The design can be used and extended for diverse applications for which Walsh-Hadamard codes
are required.
