Authors: Nasser Nidhal , Zorgati Houssem , Chtourou Hamdi , Guimard Alexandre 
Published: February 2023

Although cold water immersion (CWI) is one of the most widely used post-exercise strategies to accelerate recovery processes, the benefits of CWI may be associated with placebo effects. This study aimed to compare the effects of CWI and placebo interventions on time course of recovery after the Loughborough Intermittent Shuttle Test (LIST). In a randomized, counterbalanced, crossover study, twelve semi-professional soccer players (age 21.1 ± 2.2 years, body mass 72.4 ± 5.9 kg, height 174.9 ± 4.6 cm, V˙ O2max 56.1 ± 2.3 mL/min/kg) completed the LIST followed by CWI (15 min at 11°C), placebo (recovery Pla beverage), and passive recovery (Rest) over three different weeks. Creatine kinase (CK), C-reactive protein (CRP), uric acid (UA), delayed onset muscle soreness (DOMS), squat jump (SJ), countermovement jump (CMJ), 10-m sprint (10 mS), 20-m sprint (20 mS) and repeated sprint ability (RSA) were assessed at baseline and 24 and 48 h after the LIST. Compared to baseline, CK concentration was higher at 24 h in all conditions (p &lt; 0.01), while CRP was higher at 24 h only in CWI and Rest conditions (p &lt; 0.01). UA was higher for Rest condition at 24 and 48 h compared to Pla and CWI conditions (p &lt; 0.001). DOMS score was higher for Rest condition at 24 h compared to CWI and Pla conditions (p = 0.001), and only to Pla condition at 48 h (p = 0.017). SJ and CMJ performances decreased significantly after the LIST in Rest condition (24 h: −7.24%, p = 0.001 and −5.45%, p = 0.003 respectively; 48 h: −9.19%, p &lt; 0.001 and −5.70% p = 0.002 respectively) but not in CWI and Pla conditions. 10 mS and RSA performance were lower for Pla at 24 h compared to CWI and Rest conditions (p &lt; 0.05), while no significant change was observed for 20 mS time. These data suggests that CWI and Pla intervention were more effective than the Rest conditions in recovery kinetics of muscle damage markers and physical performance. Furthermore, the effectiveness of CWI would be explained, at least in part, by the placebo effect.

The study aimed to determine the test-retest reliability of exercise-induced gastrointestinal syndrome (EIGS) biomarkers, and assess the association of pre-exercise short chain fatty acid (SCFA) concentration with these biomarkers in response to prolonged strenuous exercise. Thirty-four participants completed 2 h of high-intensity interval training (HIIT) on two separate occasions with at least 5-days washout. Blood samples were collected pre- and post-exercise, and analysed for biomarkers associated with EIGS [i.e., cortisol, intestinal fatty-acid binding protein (I-FABP), sCD14, lipopolysaccharide binding protein (LBP), leukocyte counts, in-vitro neutrophil function, and systemic inflammatory cytokine profile]. Fecal samples were collected pre-exercise on both occasions. In plasma and fecal samples, bacterial DNA concentration was determined by fluorometer quantification, microbial taxonomy by 16S rRNA amplicon sequencing, and SCFA concentration by gas-chromatography. In response to exercise, 2 h of HIIT modestly perturbed biomarkers indicative of EIGS, including inducing bacteremia (i.e., quantity and diversity). Reliability analysis using comparative tests, Cohen’s d, two-tailed correlation, and intraclass correlation coefficient (ICC) of resting biomarkers presented good-to-excellent for IL-1ra (r = 0.710, ICC = 0.92), IL-10 (r = 0.665, ICC = 0.73), cortisol (r = 0.870, ICC = 0.87), and LBP (r = 0.813, ICC = 0.76); moderate for total (r = 0.839, ICC = 0.44) and per cell (r = 0.749, ICC = 0.54) bacterially-stimulated elastase release, IL-1β (r = 0.625, ICC = 0.64), TNF-α (r = 0.523, ICC = 0.56), I-FABP (r = 0.411, ICC = 0.21), and sCD14 (r = 0.409, ICC = 0.38), plus fecal bacterial α-diversity; and poor for leukocyte (r = 0.327, ICC = 0.33) and neutrophil (r = 0.352, ICC = 0.32) counts. In addition, a medium negative correlation was observed between plasma butyrate and I-FABP (r = −0.390). The current data suggest a suite of biomarkers should be used to determine the incidence and severity of EIGS. Moreover, determination of plasma and/or fecal SCFA may provide some insight into the mechanistic aspects of EIGS instigation and magnitude in response to exercise.

IntroductionIn China, alfalfa (Medicago sativa L.) is often grown on marginal land with poor soil fertility and suboptimal climate conditions. Soil salt stress is one of the most limiting factors for alfalfa yield and quality, through its inhibition of nitrogen (N) uptake and N fixation.MethodsTo understand if N supply could improve alfalfa yield and quality through increasing N uptake in salt-affected soils, a hydroponic experiment and a soil experiment were conducted. Alfalfa growth and N fixation were evaluated in response to different salt levels and N supply levels.Results and discussionThe results showed that salt stress not only significantly decreased alfalfa biomass, by 43%–86%, and N content, by 58%–91%, but also reduced N fixation ability and N derived from the atmosphere (%Ndfa) through the inhibition of nodule formation and N fixation efficiency when the salt level was above 100 mmol Na2SO4 L–1. Salt stress also decreased alfalfa crude protein by 31%–37%. However, N supply significantly improved shoot dry weight by 40%–45%, root dry weight by 23%–29%, and shoot N content by 10%–28% for alfalfa grown in salt-affected soil. The N supply was also beneficial for the %Ndfa and N fixation for alfalfa with salt stress, and the increase reached 47% and 60%, respectively. Nitrogen supply offset the negative effects on alfalfa growth and N fixation caused by salt stress, in part through improving plant N nutrition status. Our results suggest that optimal N fertilizer application is essential to alleviate the loss of growth and N fixation in alfalfa in salt-affected soils.
Bottom-up transdiagnostic personality subtypes are associated with state psychopathology: A latent profile analysis
Authors: Soodla Helo Liis , Akkermann Kirsti 
Published: February 2023

IntroductionPersonality-based profiling helps elucidate associations between psychopathology symptoms and address shortcomings of current nosologies. The objective of this study was to bracket the assumption of a priori diagnostic class borders and apply the profiling approach to a transdiagnostic sample. Profiles resembling high-functioning, undercontrolled, and overcontrolled phenotypes were expected to emerge.MethodsWe used latent profile analysis on data from a sample of women with mental disorders (n = 313) and healthy controls (n = 114). 3–5 profile solutions were compared based on impulsivity, perfectionism, anxiety, stress susceptibility, mistrust, detachment, irritability, and embitterment. The best-fitting solution was then related to measures of depression, state anxiety, disordered eating, and emotion regulation difficulties to establish clinical significance.ResultsA 5-profile solution proved best-fitting. Extracted profiles included a high-functioning, a well-adapted, an impulsive and interpersonally dysregulated, an anxious and perfectionistic, and an emotionally and behaviorally dysregulated class. Significant differences were found in all outcome state measures, with the emotionally and behaviorally dysregulated class exhibiting the most severe psychopathology.DiscussionThese results serve as preliminary evidence of the predictive nature and clinical utility of personality-based profiles. Selected personality traits should be considered in case formulation and treatment planning. Further research is warranted to replicate the profiles and assess classification stability and profiles’ association with treatment outcome longitudinally.

BackgroundThe worldwide prevalence of eczema has continued to rise over the past decades. This has led to the emphasis on the association between air pollution and eczema. This study investigated the relationship between daily exposure to air pollution and the number of eczema outpatient visits in Guangzhou with the overarching goal of providing novel insights on the interventions for eczema aggravation and prevention.MethodsDaily air pollution data, meteorological data, and the number of eczema outpatients were obtained from 18 January 2013 to 31 December 2018 in Guangzhou. A generalized additive model with Poisson distribution was used to assess the association between the number of eczema outpatient visits and short-term exposure to PM2.5 and PM10. In addition, the association of PM2.5 and PM10 by age (&lt;65 years, ≥65 years) and gender was evaluated.ResultsA total of 293,343 eczema outpatient visits were recorded. The obtained results indicated that a 10 μg/m3 increase of the same day/lag 1 day/lag 2 days PM2.5 was associated with increments of 2.33%, 1.81%, and 0.95% in eczema outpatient risk, respectively. On the other hand, a 10 μg/m3 increase of PM10 was associated with eczema outpatients risk increments of 1.97%, 1.65%, and 0.98% respectively. Furthermore, the associations of PM on the increment of eczema were similar in the male and female groups. Results obtained after age stratified analyses indicated that the strongest positive association between PM2.5 exposure and eczema was observed at lag 0 day with the percent changes being 4.72% and 3.34% in &lt;12 years old, ≥12 and &lt;65 years old, and ≥65 years old groups, respectively.ConclusionShort-term exposure to PM2.5 and PM10 increases the number of eczema outpatients, especially among children and the elderly. The relationship between air quality trends and hospital resource arrangement should be paid attention to by hospital managers which may aid in disease prevention and lower the health burden.

BackgroundIn low-and middle-income countries, no conclusive research explains the prevalence and associated factors of women with a history of recurrent pregnancy loss (RPL). Some authorities have recommended further scientific research on the effect of various definitions of RPL.ObjectiveTo assess prevalence and associated factors of RPL among pregnant women in Nigeria according to different national and international criteria: the American Society for Reproductive Medicine/ European Society for Human Reproduction and Embryology (ASRM/ESHRE; two losses) and the World Health Organization/ Royal College of Obstetricians and Gynecologists (WHO/RCOG; three consecutive losses) criteria.MethodsThis is a cross-sectional analytical study wherein, pregnant women with prior RPL were investigated. The outcome measures were prevalence and risk factors. The associations between independent variables and outcome variable were explored using bivariate and multivariable logistic regression models. The results of these analyses were reported as adjusted odds ratios (AORs) with 95% confidence intervals (95%CI). Factors associated with RPL were identified using multivariate regression models.ResultOf the 378 pregnant women interviewed, the overall prevalence of RPL in this study was found to be 15.34% (95% confidence interval = 11.65%–19.84%). The prevalence of RPL was 15.34% (58/378; 95%CI = 11.65%–19.84%) and 5.29% (20/378; 95%CI = 3.23%–8.17) according to the ASRM and the WHO criterion respectively. Regardless of diagnostic criteria, unexplained (AOR = 23.04; 95%CI: 11.46–36.32), endocrine disturbances (AOR = 9.76; 95%CI: 1.61–63.19), uterine abnormalities (AOR = 13.57; 95%CI: 3.54–50.60), and antiphospholipid syndrome (AOR = 24.59; 95%CI: 8.45–71.04) were positively and independently associated with RPL. No significant risk factors were seen when the ASRM/ ESHRE criterion vs. WHO/RCOG criterion were compared. Advanced maternal age was significantly higher in secondary than in primary type of RPL.ConclusionThe prevalence of RPL was 15.34% and 5.29% according to ASRM/ESHRE and WHO/RCOG criterion respectively, with secondary type predominating. No significant differences with regard to risk factors were seen according to diagnostic criteria studied, though advanced maternal age was significantly higher in secondary RPL. Further research is needed to confirm our findings and to better characterize the magnitude of differences.

Published: February 2023

IntroductionAfrican swine fever in Vietnam is contributing to existing concerns over zoonotic disease transmission from sick pigs to humans. While slaughterhouses are key sites of occupational hazards to workers and contamination of meat, the specific slaughtering practices contributing to zoonotic occupational and foodborne disease risks remain under-researched. Our objective is to identify and characterize aspects of pig slaughtering processes that contribute to such risks.MethodsWe draw on qualitative observations, photos, and videos from three mobile slaughterhouses and seven abattoirs in Hung Yen, Vietnam.ResultsBased on our analysis, areas likely leading to zoonotic disease risks include slaughtering procedures, personal hygiene of workers, equipment sanitation, and facility sanitation. Within the small-scale swine industry, slaughtering practices are long-standing and difficult to change.ConclusionOur study underscores the importance of hygiene training of workers, improvements to equipment and facilities, and awareness-building activities targeting consumers to reduce the burden of zoonotic disease risks in small-scale pig slaughter settings.

PurposeTo determine the incidence and risk factors of deep vein thrombosis (DVT) of lower extremities at admission in elderly Chinese patients with femoral neck fracture, and to establish and evaluate a new DVT predictor based on these risk factors.MethodsPatients who were hospitalized from January 2018 to December 2020 at three independent centers were reviewed. According to the results of lower extremities vascular ultrasound at admission, they were divided into DVT group and non-DVT group. Single and multivariate logistic regression analysis were applied to identify independent risk factors for DVT occurrence, and then a prediction formula for DVT based on the risk factors was developed. The new predictive index of DVT was calculated by the formula. Receiver operating characteristic (ROC) curve analysis was used to determine the diagnostic value of different factors and the new predictive index.ResultsThere were 203 elder patients were included in the final analysis after application of the exclusion criteria. Thirty seven patients (18.2%) were diagnosed as DVT by ultrasound, including 33 patients (89.2%) of peripheral type, 1 patient (2.7%) of central type and 3 patients (8.1%) of mixed type.Multivariate logistic regression analysis showed that four factors including injured side, hemoglobin, fibrinogen, d-dimer were the independent risk factors for the incidence of DVT. On this basis, a new formula for DVT predictive factor was constructed: New predictive index = 0.895 * injured side (right = 1, left = 0) + 0.899 * hemoglobin (&lt;109.5 g/L = 1, &gt; 109.5 g/L = 0) + 1.19 * fibrinogen (&gt;4.24 g/L = 1, &lt; 4.24 g/L = 0) + 1.221* d-dimer (&gt;2.4 mg/L = 1, &lt; 2.4 mg/L = 0). The AUC value of this new developed index was 0.735.ConclusionsThis work showed that the incidence of DVT in elderly patients with femoral neck fracture in China was high at admission. New DVT predictive value can be used as an effective diagnosis strategy for evaluation of thrombosis at admission.

Authors: Pop Nicolae 
Published: February 2023

In this paper a model based on non-smooth equations is proposed for solving a non-linear and non-differential equation obtained by discretization of a quasi-variational inequality that models the frictional contact problem. The main aim of this paper is to show that the Newton method based on the plenary hull of the Clarke generalized Jacobians (the non-smooth damped Newton method) can be implemented for solving Lipschitz non-smooth equation.

Authors: Berinde Vasile , Khan Abdul Rahim , Păcurar Mădălina 
Published: February 2023

We study analytically and empirically the rate of convergence of two \(k\)-step fixed point iterative methods in the family of methods\[x_{n+1}=T(x_{i_0+n-k+1},x_{i_1+n-k+1},\dots, x_{{i_{k-1}+n-k+1}}),\,n\geq k-1,\] where \(T\colon X^k\rightarrow X\) is a mapping satisfying some Presic type contraction conditions and \((i_0,i_1,\dots,i_{k-1})\) is a permutation of \((0,1,\dots,k-1)\). We also consider the Picard iteration associated to the fixed point problem \(x=T(x,\dots,x)\) and compare analytically and empirically the rate and speed of convergence of the three iterative methods. Our approach opens a new perspective on the study of the rate of convergence / speed of convergence of fixed point iterative methods and also illustrates the essential difference between them by means of some concrete numerical experiments.

Caste Rejection Thoughts in Siddhar Songs
Authors: R Ramalakshmi 
Published: February 2023

Siddhar literature is still a unique literature in Tamil literature. The Siddhas have formulated their principles and doctrines in grammar. The word community means not only people living together but also living together based on an order in a society. The set of thoughts formed about what should and should not be done by a human being in a society is called morality or ethics. Based on this virtue, various virtues including the virtue of life have been said. Through the Vedas and the Puranas, the Vaidikas, the Brahmins, portrayed themselves as superior and treated other caste people as slaves. Many were considered as untouchables and unfit based on caste hierarchies. The Siddhars have raised a revolt against the Vedics, their principles and doctrines. Caste and religion are inextricably intertwined in Indian society. They are inextricably intertwined. The Siddhars are foremost in denouncing the caste system which is the main reason for the division in the society. Siddhars who saw the inequalities that existed between them in their time, stood bravely and opposed the caste system. Caste oppression is one of the most prevalent things in Indian society. One of its inputs is the untouchability and is created as a result of a dominant mindset that does not treat fellow human beings as equals. If you touch the untouchables you will be defiled. Seeing this cruelty, the Siddhars raised their voices against untouchability. The Siddhars have also sung against untouchability as a part of caste oppression. The Siddhars condemned the Vedas for citing grass-eating as the main reason for untouchability.

AbstractThis article aims to analyze how influential the wills of the terrorists who shot at the National Police Headquarters on Wednesday, March 31, 2021. In this will, the perpetrator tells his family to stay away from the bank because of usury. The bank itself is a business entity that collects funds from its customers in the form of deposits. When viewed from the pricing, there are 2 (two) types of banks, namely conventional banks and Islamic banks. Conventional banks Implement a price system according to interest rates or commonly known as a spread base, as well as the fee base method, which means calculating the costs required. While Islamic banks apply a system of agreements in accordance with Islamic law with related parties in depositing funds and various other banking activities, there are very prominent differences between the two that make these two types of banks cannot be equalized, as stated in the terrorist's will that the bank is usury. The circulatiom of the will in the community created a negative assessment of the public’s view of the banking system Keywords: Bank, Usury, Terrorist.AbstrakArtikel ini bertujuan untuk menganalisis seberapa berpengaruh surat wasiat teroris pelaku penembakan di Mabes Polri pada Rabu, 31 Maret 2021. Dimana dalam surat wasiat tersebut terdapat suruhan pelaku kepada keluarganya untuk menjauhi bank karena riba. Bank sendiri merupakan badan usaha yang menghimpun dana para nasabahnya dalam bentuk simpanan. Jika dilihat dari penentuan harga, terdapat 2(dua) jenis bank, yakni bank konvensional dan bank syariah. Bank konvensionl Menerapkan sistem harga sesuai suku bunga atau yang biasa dikenal sebagai spread base, serta metode fee base yang artinya menghitung biaya yang dibutuhkan. Sementara bank syariah menerapkan sistem perjanjian sesuai hukum Islam dengan pihak terkait dalam penyimpanan dana dan berbagai kegiatan perbankan lainnya.Terdapat perbedaan yang sangat menonjol diantara keduanya yang membuat kedua jenis bank ini tidak bisa disama ratakan seperti yang disebutkan dalam surat wasiat pelaku teroris bahwa bank adalah riba. Beredarnya surat wasiat tersebut ditengah masyarakat menimbulkan penilaian negatif pandangan masyarakat kepada sistem perbankan.Kata Kunci : Bank, Riba, Teroris
