Acute Flare of Adult-Onset Autoimmune Enteropathy Associated With Cyclophosphamide
Authors: Liu Jasmine , Hindi Ziad , Aziz Tariq , Albashir Siwar 
Published: February 2021

ABSTRACT
This is a case of adult-onset autoimmune enteropathy (AIE) in a 46-year-old man with multiple autoimmune conditions who presented with worsening disease process after receiving cyclophosphamide. We describe the investigations and management of this patient over a 6-year timeline. The diagnosis and management of AIE is challenging given the heterogeneity in clinicopathologic findings and a small number of adult case reports. We describe the current diagnostic criteria, review the literature on treatment options and outcomes, and discuss the evidence for cyclophosphamide in the treatment of AIE. Adult-onset AIE should be considered in the differential diagnosis of refractory diarrhea and weight loss.

Authors: Chan Sandy , Wassef Wahid 
Published: February 2021

ABSTRACT
Pancreatic metastases from ovarian carcinoma are rare. We present a case of a patient with pancreatic metastasis from primary ovarian carcinoma diagnosed by endoscopic ultrasound-guided fine-needle aspiration. Our case illustrates a unique presentation of a patient with ovarian carcinoma presenting with symptoms secondary to common bile duct dilatation from a pancreatic head mass confirmed through a much less invasive approach. This diagnosis was essential in determining management and prognosis for the patient.

INTRODUCTION:
The “six-and-twelve” prognostic score was proposed recently to predict survival rate in patients with unresectable hepatocellular carcinoma (HCC) treated with transarterial chemoembolization (TACE). However, it has not been validated externally. We validated this score and previous prognostic scores in Thai HCC patients treated with TACE.

METHODS:
We identified all HCC patients who underwent TACE between January 2007 and December 2018 at our hospital. The inclusion criteria were treatment-naive, unresectable HCC BCLC-A and BCLC-B; if cirrhosis was present, Child-Pugh score ≤7; and baseline performance status 0–1.

RESULTS:
Of 716 HCC patients undergoing TACE, 281 (mean age, 61.1 years; 73.0% men, 92.2% with cirrhosis) were eligible. Approximately half of the patients had hepatitis B virus. Median overall survival was 20.3 (95% confidence interval, 16.4–26.3) months. By stratifying with the “six-and-twelve” score (≤6, >6–12, >12), median (95% confidence interval) overall survival was 35.1 (26.4–53.0), 16.0 (11.6–22.6), and 7.6 (5.4–14.9) months, respectively. Area under the receiver operating characteristic curves (AUROCs) predicting death at 1, 2, and 3 years for the “six-and-twelve” score were 0.714, 0.700, and 0.688, respectively. Compared with the other currently available scores, the AUROC predicting death at 1 year for the “six-and-twelve” score was the most predictive and better than other models except the up-to-seven model.

DISCUSSION:
Our study confirms the value of the “six-and-twelve” score to predict survival rate of unresectable HCC treated with TACE. However, in our validation cohort, AUROC of the “six-and-twelve” score was slightly lower than that of the original Chinese cohort (0.73).

Published: February 2021

INTRODUCTION:
During the coronavirus disease 2019 (COVID-19) pandemic, endoscopists have high risks of exposure to exhaled air from patients during gastroscopy. To minimize this risk, we transformed the oxygen mask into a fully closed negative-pressure gastroscope isolation mask. This study aimed to evaluate the effectiveness, safety, and feasibility of use of this mask during gastroscopy.

METHODS:
From February 28, 2020, to March 10, 2020, 320 patients undergoing gastroscopy were randomly assigned into the mask group (n = 160) or conventional group (n = 160). Patients in the mask group wore the isolation mask during gastroscopy, whereas patients in the conventional group did not wear the mask. The adenosine triphosphate fluorescence and carbon dioxide (CO2) concentration in patients' exhaled air were measured to reflect the degree of environmental pollution by exhaled air. Patients' vital signs, operation time, and adverse events during endoscopy were also evaluated.

RESULTS:
Four patients were excluded because of noncooperation or incomplete data. A total of 316 patients were included in the final analysis. The difference between the highest CO2 concentration around patients' mouth and CO2 concentration in the environment was significantly decreased in the mask group compared with the conventional group. There was no significant difference in the adenosine triphosphate fluorescence, vital signs, and operation time between the 2 groups. No severe adverse events related to the isolation mask, endoscopy failure, or new coronavirus infection during follow-up were recorded.

DISCUSSION:
This new isolation mask showed excellent feasibility of use and safety compared with routine gastroscopy during the COVID-19 pandemic.
Translanguaging practice: creative mind of a bilingual scholar
Authors: Wang Buyi 
Published: February 2021

AbstractRecently, research theorizing bilinguals’ fluid and transcending language practices has flourished. As the strategic use of more than one named language in meaning-making begins to gain validation, educators and researchers have explored the pedagogical implications of such practices in the understanding and education of bilinguals. Aligning with these explorations, this article presents a case study of a bilingual scholar’s meaning-making practice. Relying on a translanguaging lens and a multilingual perspective on creativity, I document how Professor Wang, a Chinese-American anthropologist, utilizes his full communication toolkit to navigate the academic activities of teaching, researching and writing. The findings suggest Wang translanguages to achieve the purpose of culture learning and representation. Particularly, translanguaging creativity emerges as perceived boundaries between named languages are crossed. This study of an experienced bilingual aims to inform our understanding of how to support emergent bilinguals in reaching their full learning potential in our schools.
Free boundary minimal surfaces in the unit three-ball via desingularization of the critical catenoid and the equatorial disc
Authors: Kapouleas Nikolaos , Li Martin Man-chun 
Published: February 2021

Abstract
We construct a new family of high genus examples of
free boundary minimal surfaces in the Euclidean unit 3-ball
by desingularizing the intersection of a coaxial pair of a critical catenoid and an equatorial disc.
The surfaces are constructed by singular perturbation methods and have three boundary components.
They are the free boundary analogue of the
Costa–Hoffman–Meeks surfaces and the surfaces constructed by
Kapouleas by desingularizing coaxial catenoids and planes.
It is plausible that the minimal surfaces we constructed here are the same as the ones obtained recently by Ketover
by using the min-max method.

Published: February 2021

Abstract

Objectives
Recent studies have shown a potential link between chronic exposure to Bisphenol A (BPA) and exogenous obesity, the prevalence of which has been increasing dramatically in all age groups and particularly among children in the last decades. In this study, we aimed at comparing BPA exposure levels between controls and otherwise healthy, drug-naive, pre-pubertal children having exogenous obesity with/without metabolic syndrome.

Methods
A total of 63 pre-pubertal children with exogenous obesity whom 27 of them having metabolic syndrome attending Hacettepe University Ihsan Dogramaci Children’s Hospital were included in this study. The control group consisted of 34 age- and sex-matched healthy children with no significant underlying medical conditions. Urinary BPA levels were measured using LC-MS/MS (high-performance liquid chromatography coupled with tandem mass spectrometry) methodology.

Results
Urinary BPA levels among obese children were significantly higher than those of the control group (median: 22.9 μg/g-creatinine and 6.9 μg/g-creatinine, respectively; p=0.0001). When adjusted with generalized linear models for age, gender and z scores of body mass index, obese children having metabolic syndrome had significantly higher urinary BPA levels than obese children without metabolic syndrome and both obese groups had considerably elevated levels of urinary BPA than the controls (estimated marginal mean ± standard error: 42.3 ± 7.4 μg/g-creatinine, 22.6 ± 3.5 μg/g-creatinine and 12.1 ± 2.5 μg/g-creatinine, respectively, p=0.0001)

Conclusions
This study shows much higher BPA exposure among obese children with metabolic syndrome during the prepubertal period.

Published: February 2021

Abstract

Objectives
Current treatment protocols in acute lymphoblastic leukemia (ALL) are associated with high remission rates and long life expectancy, enhancing the importance of quality of life and prevention of treatment-related complications in patient care. As osteoporosis is a frequent complication in patients under chemotherapy, we investigated the effect of vitamin K2 (100 mcg menaquinone-7) and vitamin D3 (10 mcg calcitriol) on bone metabolism in children with ALL.

Methods
Twenty-nine consecutive patients recently diagnosed with B precursor ALL (B-ALL) and treated according to the Turkish Acute Lymphoblastic Leukemia Berlin Frankfurt Münster 2000 protocol were randomly assigned into study and control groups. The study group (n=15, M/F: 8/7, age 1–14.5 years, mean 6.5 years) received vitamin K2 and vitamin D3 with their chemotherapy, while the control group (n=14, M/F 9/5, age 2–17 years, mean 7.1 years) received chemotherapy only. Serum calcium, phosphorus, magnesium, alkaline phosphatase, bone-specific alkaline phosphatase, uncarboxylated osteocalcin (ucOC), tartrate resistant acid phosphatase 5b, carboxyl terminal procollagen propeptide (PICP), osteoprotegerin (OPG), and receptor activator nuclear kappa B ligand (RANKL) were measured and bone mineral density (BMD) was determined at baseline and first, second, third and sixth months.

Results
The study group had higher serum OPG/RANKL ratio and lower ucOC levels compared to the control group at the first month; PICP levels were higher in the study group at second and third months.

Conclusions
These results suggest an early beneficial effect of the combination of vitamin K2 and vitamin D3 on BMD in ALL patients especially during the period of intensive steroid therapy in the first months.

Abstract

Objectives
This multicenter retrospective study aimed to compare the effects of HES and gelatin (GEL) on the risk of post-OLT AKI.

Method
A total of 1,672 patients undergoing OLT were enrolled from major transplant centers in China between 2005 and 2013. These patients were divided into three groups: GEL, hydroxyethyl starch (HES), and GEL + HES group.

Results
There was no significant difference in the incidence of post-OLT AKI among the GEL, HES, and GEL + HES groups. The GEL + HES group had a lower incidence of stage II post-OLT AKI than the other two groups. Compared with patients receiving GEL, patients receiving HES did not harbor an increased risk of AKI. Our results showed that MELD score (adjusted odds ratio [OR], 1.579; 95% confidence interval [CI], 1.123–2.219; P = 0.009) and preoperative anemia (adjusted OR, 1.533; 95% CI, 1.212–1.939; P < 0.001) were independent risk factors for post-OLT AKI, and normal preoperative Scr level (vs abnormal; adjusted OR, 0.402; 95% CI, 0.222–0.729; P = 0.003) was independent protective factors for post-OLT AKI.

Conclusion
This large-scale multicenter retrospective study found that the intraoperative use of HES did not increase the overall incidence of post-OLT AKI in patients when compared with GEL, and whether to increase the risk of post-OLT AKI needs to be further explored.
The experimental evidence of a strong coupling regime in the hybrid Tamm plasmon-surface plasmon polariton mode
Authors: Bužavaitė-Vertelienė Ernesta , Vertelis Vilius , Balevičius Zigmas 
Published: February 2021

Abstract
Total internal reflection ellipsometry was employed for the excitation and study of hybrid Tamm plasmon-surface plasmon polaritons mode. Simple optical methodology using optical filters to cut the part of incident light spectra was proposed. Using optical filters measured energy spectra was divided into two parts where in each range only one branch of the hybrid TPP-SPP plasmonic mode was excited directly by the incident light. Present experimental studies have shown, that if the investigated system is in strong coupling, this is always enough to excite only one component of the hybrid excitation. Thus, its dispersion relation will be the same as when the excitation is done with a whole spectrum. In the case of the TPP-SPP hybrid mode where strong coupling is realized only in p-polarized light, the fitting results have shown that the strongest coupling was at the point where the noninteracting TPP and SPP curves should be crossing. The obtained Rabi splitting for the hybrid TPP and SPP modes in BK7 prism/1D PC TiO2/SiO2 (60 nm/110 nm)/TiO2 (30 nm)/Au (40 nm) multilayered structure was about 105 meV.

Published: February 2021

Abstract
How is Germany doing with respect to the fight against COVID-19? Did the German Federal and the country’s Regional Governments enact a coordinated approach, and did the sector have the opportunity to co-operate with government and have a “voice” in the policy process? Based on the results of recent empirical studies and desk-top, internet-based research, these questions are addressed and the outcome is that there were numerous programs issued by the Federal and regional German governments that buffer the effects of the crisis is having on the sector. However, the programs were not developed in co-operation with the sector and were not easy to access, particularly for small and non-professionalized nonprofits.
Effect of fiber content on the layer structure formation of fibers inside injection-molded products using short glass fiber-reinforced materials
Authors: Hamanaka Senji , Nonomura Chisato , Nguyen Thi Thanh Binh , Yokoyama Atsushi 
Published: February 2021

Abstract
This study aims to clarify the relationship between the layer structure transition of fibers caused by the change in the flow field and the thermal properties and fiber interaction when the glass fiber content is changed. Polyamide 6 samples with different short glass fiber contents were prepared, and changes in layer structure during the flow process of injection molding were compared using X-ray computed tomography. An injection-molding simulation was performed to compare the changes in the layer structure of fibers during the flow process, and the temperature distribution and shear rate distribution were obtained by numerical analysis. Furthermore, the effect of fiber interaction on the layer structure transition of fibers was considered using a relaxation function composed of the fiber content, fiber shape factor, and strain rate.
Influence of input data representations for time-dependent instrument recognition
Authors: Schwabe Markus , Heizmann Michael 
Published: February 2021

AbstractAn important preprocessing step for several music signal processing algorithms is the estimation of playing instruments in music recordings. To this aim, time-dependent instrument recognition is realized by a neural network with residual blocks in this approach. Since music signal processing tasks use diverse time-frequency representations as input matrices, the influence of different input representations for instrument recognition is analyzed in this work. Three-dimensional inputs of short-time Fourier transform (STFT) magnitudes and an additional time-frequency representation based on phase information are investigated as well as two-dimensional STFT or constant-Q transform (CQT) magnitudes. As additional phase representations, the product spectrum (PS), based on the modified group delay, and the frequency error (FE) matrix, related to the instantaneous frequency, are used. Training and evaluation processes are executed based on the MusicNet dataset, which enables the estimation of seven instruments. With a higher number of frequency bins in the input representations, an improved instrument recognition of about 2 % in F1-score can be achieved. Compared to the literature, frame-level instrument recognition can be improved for different input representations.

Abstract
Glassbrook, DJ, Fuller, JT, Wade, JA, and Doyle, TLA. Not all physical performance tests are related to early season match running performance in professional rugby league. J Strength Cond Res 36(7): 1944–1950, 2022—This study aimed to determine which physical tests correlate with early season running performance. Sixteen professional rugby league players performed the 30-15 intermittent fitness test (IFT), 1.2-km time trial, 1 repetition maximum (RM) barbell back squat, isometric midthigh pull (IMTP), countermovement jump (CMJ), barbell squat jump (SJ), and ballistic bench press throw (BBP). Bivariate Pearson's correlations and linear regression were used to compare physical tests with peak match running intensities recorded by a portable Global Positioning System and represented by peak match velocity and acceleration, as well as peak 1-, 4-, 6-, and 8-minute instantaneous acceleration/deceleration periods of play. Significant (p < 0.05) negative correlations (r = −0.55 to −0.60) were observed between the IFT and relative 1-, 4-, 6-, and 8-minute peaks, and between the relative 1RM back squat and relative 1-, 4-, 6-, and 8-minute peaks. Significant positive correlations (r = 0.52–0.84) were observed between the following physical tests and match performance pairs: IFT and peak acceleration; relative 1RM back squat and peak acceleration; SJ peak power (relative and absolute) and peak acceleration; CMJ peak force (relative and absolute) and peak acceleration; CMJ peak power (relative and absolute) and peak acceleration and 1-, 4-, 6-, and 8-minute peaks; and relative BBP peak power and peak velocity and peak acceleration. The results of this study highlight that not all generic tests of physical qualities are related to peak match running performance and only those with significant correlations are likely to be able to indicate how players may perform during match-play.

Abstract
Kollars, JM, Taber, CB, and Beyer, KS. Relative age effects in elite olympic weightlifters. J Strength Cond Res 35(5): 1223–1228, 2021—The time of year in which an athlete is born may provide an advantage developmentally for competition, known as relative age effects (RAEs). The presence of RAEs in sport may result in athletes participating less or leaving the sport early. To determine if RAEs exist in elite Olympic weightlifting, data were examined from the past 5 Olympic Games. Using retrospective competition data, a total of 953 weightlifters (595 men and 358 women) who competed in the Olympic Games between 2000 and 2016 were included in this study. Athletes were divided into lightweight, middleweight, and heavyweight for analysis. Using the subset weight classes, the observed date of birth distribution vs. the expected worldwide date of birth distribution were compared using multiple chi square tests. Relative age effects were present overall for weightlifters (χ2 = 189.428, p < 0.001), with over-representation in January (z = +12.6, 20.9%) and under-representation in June (z = −2.1, 6.3%), September (z = −3.2, 5.7%), and November (z = −3.0, 5.1%). Relative age effects were also present in men lightweight (χ2 = 74.773, p < 0.001), men middleweight (χ2 = 41.786, p < 0.001), men heavyweight (χ2 = 39.395, p < 0.001), and women lightweight (χ2 = 37.251, p < 0.001). Determining that RAEs are present in weightlifting is important because it will help maintain the amount of opportunity for all athletes regardless of when they were born in the year. Coaches should be aware of the possible advantages of training age and the effect of physical maturation as a result of these RAEs. Coaches may use this information for athlete selection, but the presence of RAEs should not discourage athletes from participating in the sport of weightlifting.
