Blood pressure status affects atrial fibrillation in diabetic end-stage renal disease
Authors: Han Kyung-Do , Hwang YouMi , Park Sang Hyun 
Published: April 2023

Introduction
The prevalence of atrial fibrillation (AF) is increasing as the elderly population continues to increase. Chronic kidney disease, diabetes, and hypertension are known risk factors for AF. Since multimorbidity exists in chronic kidney disease, it is difficult to determine the impact of hypertension alone. Furthermore, little is known about the impact of hypertension on predicting AF in diabetic end-stage renal disease (ESRD). Here, we evaluated the effect of differential blood pressure control on AF prevalence among the diabetic ESRD population.

Methods
From the Korean National Health Insurance Service database, 2 717 072 individuals with diabetes underwent health examinations during 2005–2019. Exactly 13 859 individuals with diabetic ESRD without a prior history of AF were selected and included in the analysis. Based on blood pressure level and previous hypertension medication history, we subdivided them into five groups: normal (normotensive), pre-hypertension, new onset hypertension, controlled hypertension, and uncontrolled hypertension. AF risk according to the blood pressure groups was estimated using Cox proportional-hazards models.

Results
Among the five groups, the new onset hypertension, controlled hypertension, and uncontrolled hypertension groups showed a higher AF risk. In patients on antihypertensives, diastolic blood pressure ≥100 mmHg was significantly associated with AF risk. High pulse pressure showed a significant risk for AF in patients on antihypertensives.

Conclusion
In patients with diabetic ESRD, overt hypertension and a history of hypertension impacts AF. AF risk was higher in the ESRD population with diastolic blood pressure ≥100 mmHg and pulse pressure >60 mmHg.

Abstract

Objectives
Define the cutoff thresholds of the Kappa (K) and Lambda (L) free light chains (FLC) indices for the detection of intrathecal immunoglobulin synthesis (IIS) using the new K and L FLC ELISA from SEBIA. The reference technique, which is not readily standardized between laboratories, is based on the demonstration of oligoclonal banding (OCB) in cerebrospinal fluid (CSF) which is absent in serum. For the past 6 years, we have also routinely calculated the K FLC index using The Binding Site (TBS) reagents on an Optilite instrument, an approach increasingly used as an alternative and/or a complement to electrophoretic analysis.

Methods
We analyzed 391 serum/CSF pairs divided into three groups. The first group were cases without OCB and with normal albumin CSF/serum ratio (n=174). The second group were cases with specific OCB (n=73). The last group included patients with increased albumin CSF/sera ratio without OCB (n=142).

Results
Analysis of the first group determined that the cutoffs for detection of IIS are respectively 2.55 and 1.02 for the K FLC and L FLC indices. Of the 73 cases with IIS, only 2 had a K FLC index below this threshold (sensitivity of 97.26%), while 16 out of 73 cases (78.08%) and 13 out of 72 cases (81.94%) had an IgG and L FLC index below the cutoffs, respectively. Additionally, we illustrate equivalent performances for prediction of the presence of OCB between SEBIA and TBS methods.

Conclusions
Sebia K FLC and L FLC assays are adequate alternative methods for the diagnosis of IIS.
Compact dual-band narrowband bandpass filter with small frequency ratio

Published: April 2023

Abstract
A compact but very simple dual-band bandpass filter (BPF) based on just five pairs of coupled lines is designed in this paper. It can be examined using the even- and odd-mode method because of its symmetry structure. Six transmissions zeros (TZs) can be obtained and calculated by using input impedance analysis. For demonstration, a dual-band narrowband BPF example with center frequencies at 0.94 and 1.12 GHz is fabricated and measured. The 3-dB fractional bandwidths of two passbands are 2% (0.93–0.95 GHz) and 3.4% (1.1–1.14 GHz), whose frequency ratio of upper-band to lower-band is very small. The measurement results agree with the simulation results, confirming the design process.
Growth of CuO nanoparticles using one step chemical bath deposition under microwave heating and their characterizations
Authors: Rai Ravi Shankar , Bajpai Vivek 
Published: April 2023

Abstract
Varied morphologies of crystalline copper oxide nanoparticles were synthesized using one step chemical bath deposition under microwave heating of prepared growth solution at 1200 W microwave power for a very short duration of 2–8 min. The structure and crystallinity of the as grown copper oxide nanoparticles were studied by wide angle X-ray diffractometer analysis. The particle size values obtained from Scherrer’s relation and the Williamson–Hall plot methods are in the 16–18 nm range. The approximate size of as grown copper oxide nanoparticles evaluated from field emission scanning electron microscopic images are in the range of approximately 15–20 nm. The presence of copper and oxygen was verified by energy dispersive X-ray spectroscopy analysis. Their weight % and atomic % exhibits the rich amount of development of copper oxide nanoparticles in a 1:1 stoichiometric ratio. The optical properties of as grown copper oxide nanoparticles were examined by assessing absorption spectra of the sample in ultraviolet–visible range. The significant peak of absorption spectra is seen near 340 nm wavelength which explains the mono-dispersion behaviour of nanoparticles. Evaluation of Urbach energy of copper oxide nanoparticles reveals that the nanomaterial has microstructural lattice disorder. These characterizations of as synthesized copper oxide nanoparticles explain the feasibility and potential of such nanomaterial to be incorporated in a wide range of utilities.
Ironic speakers, vigilant hearers
Authors: Mazzarella Diana , Pouscoulous Nausicaa 
Published: April 2023

AbstractVerbal irony characteristically involves the expression of a derogatory, dissociative attitude. The ironical speaker is not only stating a blatant falsehood or irrelevant proposition; she is also communicating her stance towards its epistemic status. The centrality of attitude recognition in irony understanding opens up the question of which cognitive abilities make it possible. Drawing on Wilson (2009), we provide a full-fledged account of the role of epistemic vigilance in irony understanding and suggest that it relies on the exercise of first- and second-order vigilance towards the content, the ironic speaker as well as the source of the irony.

Abstract

Objectives
Imagery training is an effective technique in sport psychology for skill development and enhancement at various levels of skill performance. Despite its application, there is limited evidence to inform decisions around the appropriate doses of imagery duration for performance enhancement of movement in sport and physical activity. The aim of the present study was to experimentally determine whether different imagery durations (8, 13, and 18 min durations in a session) have differential effects on the performance of free-throw shooting (FTS) in the sport of basketball. We applied a dose-response imagery protocol, in which one imagery variable was varied systematically, while other key dose variables were held constant.

Methods
We recruited 36 male basketball players (M
age=25.17 years SD=4.26) and allocated them to one of three imagery training conditions or a control condition. Participants in the control condition had no imagery training sessions. Imagery repetitions were held constant at 20 repetitions per imagery session with a frequency of 3 imagery sessions per week over four weeks.

Results
The results showed that the 13- and 18-min imagery durations were more effective than the 8-min duration condition for the basketball free-throw shooting. The 13-min condition was significantly higher at post- and retention-test than at pre-test, indicating it was most effective in this study.

Conclusions
The findings of the present study highlight the importance of imagery duration in imagery training design and may inform coaches, sport psychologists, and athletes in designing effective programs for individual athletes.

Published: April 2023

Abstract
The addition of nano-silica to ultra-high-performance concrete (UHPC) to increase its toughness has been proposed to obtain ultra-high-performance nano-concrete (UHPNC). This work mainly studies the reinforcement effect of UHPNC on concrete filled steel tube (CFST) columns under long-term load. Ten CFST columns strengthened with UHPNC were selected and reinforced with UHPNC. The influences of different thicknesses of UHPNC reinforcement layer and different nano-silica contents on the axial compression properties of specimens were mainly studied, by loading specimens in two steps: long-term load and ultimate load. This study discussed the failure modes, compressive toughness, ultimate bearing capacity, initial stiffness, and ductility coefficient of the specimens. The results show that the outsourced UHPNC reinforcement method is an effective method to improve the performance of CFST columns during service period. With the increase in the thickness of UHPNC reinforced layer, the ultimate bearing capacity of CFST column increases greatly. The compression toughness is increased with the increase in nano-silica content and UHPNC reinforcement layer thickness. The decrease rate of initial stiffness increases with the increase in nano-silica content.

Abstract

Objectives
The lack of specific treatment for COVID-19 and the fact that the clinical course differs between individuals makes it difficult to predict the prognosis. The aim was to investigate the prognostic value of total thiol, D-dimer, procalcitonin (PCT), ischemia-modified albumin (IMA), and complete blood count (CBC) in patients hospitalized with COVID-19.

Methods
100 consecutive patients were hospitalized with COVID-19, confirmed by RT-PCR between December 2021-March 2022 and 30 healthy control participated in the study. According to the World Health Organization guideline, two groups were created as critical and non-critical. D-dimer, PCT, IMA, total thiol levels, and CBC were analyzed. Receiver-operating characteristic curves (ROC) were utilized to determine an optimum cut-off value for distinction.

Results
We defined a cut-off value of 1,030 μg/L for D-dimer (Area Under Curve, AUC): 0.691; p=0.001) and 148 μmol/L for total thiol (AUC: 0.749; p<0.001) via ROC analysis. The combination of D-dimer and total thiol reached 65% positive predictive value (PPV) and 80% negative predictive value (NPV).

Conclusions
D-dimer and total thiol may help predict critical patients with COVID-19.

Irving’s Literary Historiography
Authors: Stokes Claudia

Claudia Stokes, “Irving’s Literary Historiography” (pp. 195–222)
This essay examines the importance of Washington Irving to modern disciplinary standards of historiography. Today, history and literature are distinct genres requiring different skills, but for centuries history was a recognized form of rhetoric readily available to writers, even those without special qualifications or training. This tradition of history writing proved important to Irving’s early career, and he found great success with his parodic A History of New York (1809). Decades later, he attempted to replicate that success with A Chronicle of the Conquest of Granada (1829), a history of Spain’s campaign to control Granada. However, in the intervening years, historiographical standards had begun to change: historians were now expected to conduct original research and adhere as closely as possible to recorded facts. In accord with these expectations, Irving conducted significant archival research, but he blended this research with literary forms and devices, which included a fictitious narrator and an invented manuscript source. Decades earlier, these devices had rendered A History of New York a success, but critics of Conquest of Granada took issue with Irving’s literariness and accused him of perpetrating a hoax. To nineteenth-century observers, this controversy demonstrated the dangers that literariness posed to history and affirmed the need to separate these two modes. The public response to Irving’s A History of the Conquest of Granada contributed to the modern professionalization of history and modern historiographical standards.

ABSTRACT

INTRODUCTION
Overweight and obesity are becoming a major health issue which contributes to increase in health morbidity and mortality. This study aimed to evaluate the effect of the mainly diet intervention and exercise for weight reduction among obese but healthy adults.

METHODOLOGY
This was a quasi-experimental study using designed Structured Diet Program adapted from Malaysia Healthy Plate method (half-half quarter) for weight reduction that lasts for 10 weeks. The anthropometry and biochemistry parameters were monitored and collected pre and 10 weeks post program. The WHO BMI criteria for Asian population cut off points was used to define obesity in this study.

RESULT
Thirty healthcare workers (HCWs) were recruited. However, only 27 HCWs completed the program. The pre and post program mean BMI was 32.90kg/m2 and 31.39kg/m2 and weight was 81.25 kg to 77.37kg. The total cholesterol reduced significantly with mean 5.65mmol/l to 5.34mmol/l. Other blood parameters showed some reduction but not statically significant with mean FBS 4.82mmol/l to 4.69mmol/l, mean HDL: 1.43mmol/l to 1.32mmol/l mean LDL: 3.54mmol/l to 3.42mmol/l and mean TG 1.52mmol/l to 1.31mmol/l.

CONCLUSION
Overall, the programme led to a considerable reduction in body weight, BMI, and Total Cholesterol. Even though other blood parameters do not show statistically significant reduction but they still showed some reduction post programme. This method is recommended to be implemented among Malaysians for longer duration to achieve significant reduction in blood parameters. However, the commitment and motivation of the HCWs are highly needed to ensure the effectiveness and adherence to the diet method.
