Abstract
Purpose: The nurses work long hours and in various shifts, and often accompanied by depression, fatigue and sleep disorders. Many studies have found that vitamin D is related to mental health. We aimed to investigate the relationship between depression, sleep problems, fatigue, and serum vitamin D3 levels in shift nurses as a basis for improving their mental health. Methods: We recruited 34 day-shift, 30 evening-shift and 31 night-shift nurses. The questionnaires used are: The Beck Depression Inventory II (BDI-II), Numerical Rating Scale and General Sleep Disturbance Scale. Results: Approximately 96.1% of shift nurses had deficient (<20 ng/ml) and inadequate (20–29 ng/ml) vitamin D3 levels. Approximately 84.2% of shift nurses experienced fatigue. Night-shift nurses experienced significantly more severe sleep disturbance than day-shift and evening-shift nurses. However, no significant correlation was observed between vitamin D3 levels and mental health when the vitamin D3 level was categorized.Conclusion: Vitamin D3 deficiency, sleep disturbance, depression, and fatigue were common in shift nurses, but it was not possible to demonstrate the impact of vitamin D3 deficiency on the mental health of shift nurses. However, the relationship between serum vitamin D3 levels and mental health in shift nurses could not be ignored.

Abstract
Background The prognostic value of International Prognostic Index (IPI) of primary breast lymphoma (PBL) remain controversial. The present study aimed to evaluate the prognostic value of IPI in patients with PBL in a Chinese population. Methods We searched the published cohort studies regarding PBL and summarized 25 studies on the prognostic value of IPI in PBL. Then a multicenter retrospective study of 71 patients with PBL was performed. The Kaplan–Meier method and log-rank tests were used for the survival analysis. Cox regression analysis was performed to evaluate the prognostic factors. Subgroup analysis was performed to assess the prognostic significance of IPI scores.Results The median follow-up was 4.7 years (range, 0.7–21.8 years). The 5-year progression-free-survival (PFS) and overall survival (OS) rates were 90.2% and 96.3%. In the multivariate analysis, only IPI scores and radiotherapy were signiﬁcantly associated with OS and PFS (P < 0.05). Subgroup analyses showed survival analysis of IPI scores for the PFS and OS of patients using rituximab were not significantly different (P > 0.05). Conclusions Our study confirms the prognostic value of IPI in patients with PBL, but the prognostic value of IPI proved to be relatively low with the addition of the rituximab.

Published: April 2022

Abstract
Purpose:
The study aimed to determine the various indications for PCN primarily in patients with a urinary tract infection, and to determine the various complications arising in these patients due to the procedure.
Materials and methods
A retrospective study of 5-years data based on registers of the Department of Urology was performed. Among 716 patients, 226 inpatient data were obtained, curated, and analyzed. Indications for PCN, the periprocedural complications, the PCN's duration, details of antibiotics, risk factors for UTI, development of acute kidney injury, and renal replacement therapy were recorded.
Results
Patients were mostly female (53.1%, n = 120/226). Malignancy (n = 109, carcinoma cervix = 68/109) and nephrolithiasis (n = 70) contributed to 79.2%. Infections such as pyelonephritis, renal abscess, perinephric abscess, and genitourinary tuberculosis were identified in 47. Infectious diseases were significantly associated with younger age, female gender, diabetes, and prior pyelonephritis. PCN was placed a median of two days after admission, and bilateral PCN was placed in 36 (15.2%) patients. Hydroureteronephrosis (probably infected) was an indication for PCN in 164/226 patients. In 33 patients with an infectious disease, PCN was performed for an obstructed urinary system. One major and two minor complications gave a rate of 0.06% for patients with infections, which was less than the accepted threshold of 4%.
Conclusion
We intended to study the utility and problems with placing a percutaneous nephrostomy (PCN) catheter in patients with complicated urinary infections. We conclude that PCN is a safe and effective procedure in urinary tract infections with obstructed drainage.

Authors: G Abhinand , V Uma Maheswari 
Published: April 2022

Abstract
This study aims to understand the corroboration of the results of Sentimental analysis with Event Analysis on the Indian Budget 2022 announcement on cryptocurrency. Sentimental analysis tries to classify the tweets on Bitcoin on the budget day into Positive or Negative and deciphers the overall sentiment of the bitcoin investors on the Budget Day and the subsequent 2 days. This has been made possible by using a supervised machine learning algorithm. Event Analysis identifies whether any abnormal returns are seen on the event day and the subsequent 10 days. This study observes that the range between the positive and negative sentiments is minimal and there is no abnormal returns found post the budget announcement in the event study. It may be concluded that positive sentiments nullified the negative sentiments where the overall sentiments have a mean subjectivity score that is more leaning towards the less-opinionated side, which may be accounted for the lack of abnormality was found on the event day as well as the adjustment period.
Dual Image Efficient Watermarking Technique Based on LWT-CZT-SVD and Arnold Transform with Grey Wolf Optimization
Authors: Awasthi Divyanshu , Srivast Vinay Kumar 
Published: April 2022

Abstract
In this paper, a new algorithm of multi-image watermarking is proposed for the security of multimedia data by using the features of Lifting wavelet transform (LWT), Singular value decomposition (SVD), Chirp Z-transform (CZT), and Arnold transform (AT). In the embedding procedure , split the input image into sub-bands using lifting wavelet transform and select HL and LH sub-bands for image watermarking, then apply the chirp Z-transform in the selected sub-bands and then decompose these two sub-bands by using SVD. Two watermark images are selected for embedding them into the input image, and the security of the second watermark is increased by using Arnold transform. Apply the lifting wavelet transform on both the watermark images and then transform them by SVD. Singular values (SVs) of watermarks are used to embed into SVs of the input image. The grey wolf optimization (GWO) technique is preferred here to calculate the scaling factor. Scaling factor plays very important role in the performance of watermarking. The effectiveness of the proposed algorithm is checked by applying different types of attacks. The superiority of the proposed work is mentioned in the results. Peak signal to noise ratio (PSNR), Normalized correlation coefficient (NCC) & Mean square error (MSE) is used for performance evaluation.
Cardiovascular and Renal Outcomes of the New Kid on the Block: FiFi analysis

Published: April 2022

Abstract
Finerenone is a selective nonsteroidal mineralocorticoid receptor antagonist that has been shown to reduce the urinary albumin-to-creatinine ratio in patients with CKD treated with a renin angiotensin system blocker, improving cardiovascular injury while having smaller effects on serum potassium levels than spironolactone. We aim to assess whether nonsteroidal mineralocorticoid receptor antagonists are effective in the treatment of patients with type 2 diabetes and chronic kidney disease using a systematic review approach. We searched PubMed and screened the resulting records on 10 September 2021. A total of 13026 participants were included in this analysis. Overall cardiovascular outcomes were significantly lower in the finerenone group (RR 0.88 (95% CI 0.81 to 0.96; I² = 0%; p = 0.004). Cardiovascular death had an RR of 0.88 (95% CI 0.76 to 1.02; I² = 0%), nonfatal myocardial infarction had an RR of 0.91 (95% CI 0.74 to 1.13; I² = 8%), and heart failure hospitalizations had an RR of 0.79 (95% CI 0.66 to 0.64; I² = 23%; p = 0.001). Overall renal outcomes were significantly lower in the finerenone group (RR 0.84 (95% CI 0.79 to 0.90; I² = 0%; p ≤ 0.00001). Death from renal causes had an RR of 0.86 (95% CI 0.73 to 1.01; I² = 0%). End-stage kidney disease was lower in the intervention arm (p = 0.05) (RR 0.79 (95% CI 0.63 to 1.00; I² = 10%). These results suggest that finerenone might have an additional protective effect on the cardiovascular and renal systems that is nonexistent with the use of spironolactone and eplerenone.

The primary aim of this study was to analyze the distribution of ocular parameters of children aged from eight to eighteen-year-old with low to moderate myopia as well as offer useful information for the design and clinical fitting of ortho-k lens in China.
Methods
In this retrospective study, we collected data of 300 subjects (600 eyes) age between eight to eighteen-year-old from the myopic control outpatient clinic at Beijing Tongren Hospital, Beijing, China. The spherical equivalent (SE), axial length (AL), central corneal thickness (CCT), anterior chamber depth (ACD), corneal endothelial cell density (CECD), corneal diameter (CD), simulated K (Sim K) were collected from all the subjects and analyzed.
Results
The mean of SE for all subjects was − 3.12 ± 1.21D, the median was − 3.16D. The mean of AL for all subjects was 24.72 ± 0.83 mm, the median was 24.72 mm. The mean of CCT for all subjects was 537.8 ± 29.82 µm, the median was 538.17 µm. The mean of CECD for all subjects was 3340.3 ± 352.6 cells/mm2, the median was 3357.77 cells/mm2. The mean of ACD for all subjects was 3.71 ± 0.21 mm, the median was 3.69 mm. The mean of CD for all subjects was 12.15 ± 1.67 mm, the median was 12.05 mm. The mean of flat K was 42.80 ± 1.29, the median was 42.81. The mean of steep K was 43.76 ± 1.37, the median was 43.76.
Conclusions
This study provided the distribution of ocular parameters to offer useful information for diagnosis of many eye conditions. Meanwhile, the distribution of ocular parameters of children aged from eight to eighteen-year-old with low to moderate myopia is beneficial to make the application of overnight orthokeratology lens more appropriate and effective.

Authors: Gomes Juliano de Andrade , de Souza Diego Mendes , Oliveira Karina Diniz , Gallassi Andrea Donatti 
Published: April 2022

Abstract
Background: Psychoactive substances (PASs) are an important risk factor for the suicide. This study investigated the sociodemographic characteristics, the methods employed, the circumstances of the events, and the use of PASs in all suicides that occurred between 2005-2014 in the Brazilian Federal District, besides to compare cases with positive and negative detection for PASs in the post-mortem analysis. Methods: A population-based, observational, cross-sectional study with an analytical aspect was conducted with suicides cases collected from local police, which toxicological examination was performed (headspace gas chromatographic-mass spectrometry-HS-GC/MS) for detection of ethanol and methanol in blood samples; immunoassay for other substances (cocaine, marijuana, benzodiazepines, etc.). Results: The results showed that the increase in the suicide rate was 10x greater than the population growth and 44% of the individuals used PASs before suicide. Individuals are more likely to die by suicide at home, to be male, to have tried before and to change their behaviour days before death; they chose hanging as the method and are under the influence of alcohol. Conclusion: Identifying what sociodemographic characteristics are associated with a fatal suicide attempt among individuals who use PASs and those who do not use, as well as among those who have/not have mental disorders and what methods are employed, could be a path to better interventions. Thus, prevention actions could be planned and directed to individuals with greater risk.
Experimental study on pressure characteristics of direct water hammer in the viscoelastic pipeline

Published: April 2022

Abstract
With the increasing popularity of long-distance water supply projects and the development of materials technology, the variation of water hammer characteristics in the viscoelastic pipeline has become the focus of researchers. To find out the mechanism of water hammer in the viscoelastic pipe of both elastic and viscous properties, an experiment was set up to study the direct water hammer generated by rapid closure of the downstream valve in the polymethyl methacrylate (PMMA) pipe, with six flow velocities in nearly 70 tests. The experimental results showed that the maximum water hammer pressure generated in the viscoelastic pipe in all flow velocities was (20% at most) greater than the traditional value of Joukowsky's formula. A faster closing time of the valve caused a higher water hammer pressure. The difference in water hammer pressure generated between the fastest and the slowest closing time of the valve was 14–17% at each flow velocity. Based on the relationship between the stress and strain of the pipe wall in the viscoelastic pipe, the reason that the water hammer characteristic in the viscoelastic pipeline was different from the traditional value was explained. The study provides a reference for the mechanism of transient flow in viscoelastic pipelines.

Published: April 2022

Abstract
Human rights to water and sanitation have been widely recognised in legal instruments at the international, regional, and national levels of governance. More awareness of states’ obligations has provided additional impetus to promote human rights in policy advocacy. The international non-governmental organisation WaterAid, as a non-state actor specialising in the water, sanitation, and hygiene services (WASH) sector, adopts a human rights-based approach (HRBA) to WASH programming. This paper draws on the experiences from WaterAid WASH projects in four countries – Nepal, Ghana, Mali, and Burkina Faso, to evaluate the practical impacts of the HRBA to ensure that governments fulfil their responsibility to realise universal access to water and sanitation services in different contexts. The outcomes highlight that three important contributions of the HRBA: (1) generates greater awareness among rightsholders and duty bearers about responsibilities and entitlements over safe drinking water and sanitation; (2) promotes constructive engagement between the government and rightsholders; and (3) equips people with the motivation, skills, and agency which are critical dimensions to work on sustainable WASH. The WASH sector should, therefore, embrace the power of human rights and invest in the specific activities and frameworks to integrate human rights into systems strengthening the WASH sector, while continuing to analyse and learn how to adapt and improve the approach in different contexts.
An efficient method to solve the fuzzy Crank–Nicolson scheme with application to the groundwater flow problem
Authors: Samarinas N. , Tzimopoulos C. , Evangelides C. 
Published: April 2022

Abstract
In this paper, we propose a comprehensive methodological framework for solving the fuzzy groundwater flow problem in a simpler and faster way based on numerical analysis. In particular, a novel simplified matrix explicit inverse formula is proposed as an efficient method to solve the fuzzy Finite Difference numerical scheme, called Crank–Nicolson implicit scheme. The main advantage of the proposed method is that it offers an efficient and simpler solution to the algebraic tridiagonal system of equations that appeared in the fuzzy Crank–Nicolson scheme, without affecting the accuracy of the results. Without doubt, the simulation of an unconfined aquifer flow, using the Finite Difference Method, is often time-consuming due to the costly calculations required to solve the implicit Finite Difference schemes. This process becomes even more difficult when the physical problem is solved in its fuzzy form where the calculations become more complex and greatly increase. However, problem uncertainties are not considered negligible and must be included in the final calculations for a more rational management of the water body. This creates the need to find a new and faster way to solve the fuzzy implicit schemes, as proposed in this work. The simplified matrix explicit inverse formula was applied to the fuzzy Crank–Nicolson scheme to solve the fuzzy partial differential equation of Boussinesq and, hence, the simulation of the physical problem. Its results were compared with the corresponding results of the Thomas algorithm, which until today, is the most common method of solving the tridiagonal system of equations. The case under consideration refers to a sudden rise in the lake's water level, thus resulting in the aquifer recharging from the lake. The performance of the proposed method was more than satisfactory in terms of calculation accuracy and reliability where the numerical results are matched with the differences appearing from the 12 decimal point onward between the two examined methods. The proposed method tested also considered the running times, achieving much better times compared with the Thomas algorithm, where the differences ranged from a few seconds to several hours depending on the examined time and space steps.
Use of Smartphone Health Apps Among Patients Aged 18 to 69 Years in Primary Care: Population-Based Cross-sectional Survey
Authors: Paradis Sabrina , Roussel Jeremy , Bosson Jean-Luc , Kern Jean-Baptiste 
Published: April 2022

Background
The World Health Organization has defined mobile health (mHealth) as the “use of mobile and wireless technologies to support the achievement of health objectives.” Smartphones currently represent one of the main media forms for mHealth democratization. Health apps can be an interesting tool for changing health behaviors. However, their use in France is still poorly documented.

Objective
The main aim of this study was to evaluate the frequency of use of health apps among patients consulting in the primary care setting in France. The secondary aims were to evaluate the use of health apps according to the sociodemographic and medical characteristics of patients and to determine their use.

Methods
A population-based cross-sectional survey was carried out between November 2017 and January 2018 in the Grenoble area of France among patients aged between 18 and 69 years who were consulting at 13 primary care physician offices. Patients were provided with anonymous paper self-questionnaires. The main criterion for participation was the use of a smartphone health app, defined for the purpose of this study as any app supporting patients in efforts to be healthy.

Results
The participation rate was 49.27% (739/1500; 95% CI 46.7%-51.8%). The smartphone use was estimated at 82.6% (597/723; 95% CI 79.6%-85.2%). Of 597 smartphone owners, 47.7% (283/595; CI 43.6%-51.6%) used at least one smartphone health app. Health apps identified in this study were mainly related to wellness, prevention, and fitness (66.1%), as well as medication, treatments, and follow-up care (50.0%). The main factors associated with health app use were: use of social networks (odds ratio [OR] 3.4, 95% CI 2.1-5.3), age under 30 years (OR 2.7, CI 1.4-4.9), city size between 5001 and 10,000 inhabitants (OR 1.8, CI 1.1-2.8), and city size more than 10,000 inhabitants (OR 2.1, CI 1.4-3.2).

Conclusions
In this survey, nearly one out of two patients reported the use of smartphone health apps, which are currently focused on wellness, prevention, and fitness, and are largely used by the younger population.

This study was carried out to evaluate the changes in physicochemical properties of pitaya powder produced by spray-drying under the different temperature storage at 5-7 , room temperature, and 50 for 40 days, The results showed that delta E of color increased but the content of betacyanin and total phenolic decreased following temperature increase. The degradation of betacyanin and total phenolic content in all samples during storage fitted the first-order reaction. Moreover, the behavior of moisture content in pitaya powder under different relative humidity was investigated. The isotherm curve of pitaya powder was built (y = 3,2655e0,0106x). The result also showed the GAB equation can be used to calculate the M0 of the sample better than the BET equation.
The Effect of Accumulation of Leaf Litters and Allelochemicals in the Soil to the Sustainability of the Newly Introduced Crop Plants
Authors: Adiputra I Gede Ketut 
Published: April 2022

Indonesia is the second-largest vanilla production and the third-largest cocoa production in the world, but it sustained for a short period. The unsustainability of these crops is speculated to occur because of the change in leaf litter accumulation which affected the sustainability of soil organic carbon that plays an important role in maintaining soil health and fertility. To find out methods that could improve the sustainability of the production, a literature review was conducted. The articles, related to the sustainability of vanilla and cacao production, were collected using Google Scholar, Wiley Online Library, ResearchGate, and Google Chrome browser. Keywords were employed to find the articles includingsoil organic carbon, cocoa plantation, vanilla, leaf litter, and allelochemical. This current article review foundthat introducing crop by clearing of previously existing vegetation could severely reduce the rate of leaf litter accumulation. Consequently, in a prolonged period, the soil organic carbon and soil fertility are very low and are unable to support the healthy growth and production of the crops. To restore production, the plantation then is returned to more traditional agroforestry such as replanting shading trees and addition of mulch. However, in the higher density of canopy, the crop production is low attributed partly to the decreasing soil pH which increases the impact of allelochemical. This review concluded that the sustainability of leaf litter accumulation is crucial to maintain soil health, but mitigation is required to reduce the impact of allelochemical accumulation.
