Nutrition nurse-led outpatient ‘hot’ clinics are efficient and cost-effective: a retrospective single-centre evaluation
Authors: Rogers Naomi , Woodham Diane , Fletcher Jane 
Published: April 2023

Background: Nutrition nurses work in multidisciplinary and nurse-led outpatient clinics. The daily nutrition nurse-led ‘hot’ clinic in this study sees patients for enteral or home parenteral nutritional support. Appointments may be for routine procedures or emergency reviews. Aims: This study aimed to identify activities and procedures performed in the nutrition nurse-led clinic, identifying admission avoidance activity. Methods: Nurse-held records for the period from April 2018 to March 2020 were reviewed retrospectively. Data were collated in an Excel spreadsheet for analysis and results are presented using descriptive statistics. Results: Records covered a total of 590 patients, 294 men and 296 women with a median age of 59 years, and 606 procedures. Key activities were troubleshooting enteral feeding tubes (29%), insertion of fine-bore nasogastric feeding tubes (18%) and management of home parenteral nutrition issues (11%). The presenting problem or issue was resolved in 90% of patients, with no need for hospital admission or additional medical review. Conclusion: The nutrition nurse-led clinic provides an efficient and cost-effective service, preventing hospital admission and emergency department attendance in most cases.

Published: April 2023

Integrated narrow-linewidth lasers are the key devices in compact coherent optical
systems of metrology, sensing, and optical microwave generation. Here,
we demonstrate a hybrid integrated laser based on an optical negative
feedback scheme. The laser is composed of a commercial distributed
feedback (DFB) laser diode and an on-chip micro-resonator with a
Q-factor of 0.815 million. The feedback optical field is coupled back
to the laser cavity through the back facet. Therefore, the laser can
maintain the lasing efficiency of the DFB laser diode. The linewidth
of the DFB laser diode is compressed from 2 MHz to
6 kHz, corresponding to the linewidth reduction factor of
25.2 dB. The theoretical result shows that the laser
performance still has a huge improvement margin through precise
control of the detuning between laser frequency and
the micro-resonator, as well as the phase delay of the feedback
optical field. The hybrid narrow-linewidth laser diode has wide
application prospects in coherent optical systems benefitting from the
low cost and volume productivity.
Measuring optical properties of clear and turbid media with broadband spectral interferometry
Authors: Speets Peter N. A. , Kalkman Jeroen 
Published: April 2023

The group index, n
g
, group velocity dispersion (GVD), and
scattering attenuation coefficient, μ
s
, were measured for dilutions of
glycerol, ethanol, and Intralipid 20% with water. Experiments were
performed with a supercontinuum laser based Mach–Zehnder
spectroscopic interferometry setup for wavelengths between 400 and
930 nm. All optical properties could be retrieved from a single
calibrated measurement of the interference spectrum. Scattering
attenuation was determined from the envelope of the interference. The
group index and GVD were retrieved from the unwrapped spectral phase.
It was found that the group indices of glycerol and ethanol dilutions
are in accordance with the Lorentz–Lorenz mixing formula. The
scattering attenuation matches well to a semi-empirical model based on
the Twerksy effective packing fraction.
Leaky cavity modes in metasurfaces: a route to low-loss wideband anomalous dispersion

Published: April 2023

Metasurfaces have provided unprecedented degrees of freedom in manipulating electromagnetic waves upon interfaces. In this work, we first explore the condition of wide operating bandwidth in the view of reflective scheme, which indicates the necessity of anomalous dispersion. To this end, the leaky cavity modes (LCMs) in the meta-atom are analyzed and can make effective permittivity inversely proportional to frequency. Here we employ the longitudinal Fabry–Perot (F-P) resonances and transverse plasmonic resonances to improve the LCMs efficiency. It is shown that the order of F-P resonance can be customized by the plasmonic modes, that is, the F-P cavity propagation phase should match the phase delay of surface currents excited on the meta-atom. The nth order F-P resonance will multiply the permittivity by a factor of n, allowing larger phase accumulation with increasing frequencies and forming nonlinear phase distribution which can be applied in weak chromatic-aberration focusing design. As a proof-of-concept, we demonstrate a planar weak chromatic-aberration focusing reflector with a thickness of λ0/9 at 16.0–21.0 GHz. This work paves a robust way to advanced functional materials with anomalous dispersion and can be extended to higher frequencies such as terahertz, infrared, and optical frequencies.

Published: April 2023

Whispering gallery mode (WGM) microcavities have been widely used for high-sensitivity ultrasound detection, owing to their optical and mechanical dual-resonance enhanced sensitivity. The ultrasound sensitivity of the cavity optomechanical system is fundamentally limited by thermal noise. In this work, we theoretically and experimentally investigate the thermal-noise-limited sensitivity of a WGM microdisk ultrasound sensor and optimize the sensitivity by varying the radius and a thickness of the microdisk, as well as using a trench structure around the disk. Utilizing a microdisk with a radius of 300 μm and thickness of 2 μm, we achieve a peak sensitivity of 1.18  μPa Hz−1/2 at 82.6 kHz. To the best of our knowledge, this represents the record sensitivity among cavity optomechanical ultrasound sensors. Such high sensitivity has the potential to improve the detection range of air-coupled ultrasound sensing technology.
Blue perovskite single-mode lasing in a rubidium lead bromide microcubic cavity

Published: April 2023

Lead halide perovskite microlasers have shown impressive performance in the green and red wavebands. However, there has been limited progress in achieving blue-emitting perovskite microlasers. Here, blue-emitting perovskite-phase rubidium lead bromide (RbPbBr3) microcubes were successfully prepared by using a one-step chemical vapor deposition process, which can be utilized to construct optically pumped whispering gallery mode microlasers. By regulating the growth temperature, we found that a high-temperature environment can facilitate the formation of the perovskite phase and microcubic morphology of RbPbBr3. Notably, blue single-mode lasing in a RbPbBr3 microcubic cavity with a narrow linewidth of 0.21 nm and a high-quality factor (∼2200) was achieved. The obtained lasing from RbPbBr3 microlasers also exhibited an excellent polarization state factor (∼0.77). By modulating the mixed-monovalent cation composition, the wavelength of the microlaser could be tuned from green (536 nm) to pure blue (468 nm). Additionally, the heat stability of the mix-cation perovskite was better than that of conventional CsPbBr3. The stable and high-performance blue single-mode microlasers may thus facilitate the application of perovskite lasers in blue laser fields.

How to kill a sage: North Korean discourse on Jizi/Kija 箕子
Authors: Glomb Vladimir 
Published: April 2023

Abstract
After liberation in 1945, the new North Korean regime initiated a process to liquidate so-called “old” or “feudal” thought. One prime target of the North Korean authorities was the myth of Jizi 箕子 (kor. Kija) and the story of his migration to the Korean Peninsula. The elimination of Kija and his legacy was a complicated task; the ancient legend of the Shang dynasty sage who brought civilisation and culture to the Korean people was widely known in all strata of Korean society, deeply ingrained in thousands of literary works, and the new North Korean capital, Pyongyang, was the traditional centre of the Kija cult. In spite of censorship, physical destructions of Kija-related relics, or academic conferences, which tried to repudiate the link between Kija and the Chosŏn state on a scientific basis, the North Korean authorities were never able to fully suppress the old narrative. The ancient sage remains, until nowadays, a problematic point for North Korean historiography and cultural memory.

Abstract
Combining the anomalies and environmental monitoring data of the early stage Beidou satellites, the space radiation environment spatial/temporal distribution and space radiation effect risk characteristics are analyzed, and the dynamic characteristics of space environmental factors, such as hot plasma, high-energy electron and solar proton are summarized. The systematic joint monitoring for surface charging, internal charging, single event effect and total dose effect with corresponding space environment factors is proposed. The detector types, measurement parameters range and engineering constraints are allocated, and the engineering application and scientific research of detection data are prospected.

Abstract

Objectives
Alzheimer’s disease (AD) is considered the most common cause of dementia in older people. Recently, blood-based markers (BBM) Aβ1-42, Aβ1-40, and phospho Tau181 (p-Tau181) have demonstrated the potential to transform the diagnosis and prognostic assessment of AD. Our aim was to investigate the effect of different storage conditions on the quantification of these BBM and to evaluate the interchangeability of plasma and serum samples.

Methods
Forty-two individuals with some degree of cognitive impairment were studied. Thirty further patients were retrospectively selected. Aβ1-42, Aβ1-40, and p-Tau181 were quantified using the LUMIPULSE-G600II automated platform. To assess interchangeability between conditions, correction factors for magnitudes that showed strong correlations were calculated, followed by classification consistency studies.

Results
Storing samples at 4 °C for 8–9 days was associated with a decrease in Aβ fractions but not when stored for 1–2 days. Using the ratio partially attenuated the pre-analytical effects. For p-Tau181, samples stored at 4 °C presented lower concentrations, whereas frozen samples presented higher ones. Concerning classification consistency in comparisons that revealed strong correlations (p-Tau181), the percentage of total agreement was greater than 90 % in a large number of the tested cut-offs values.

Conclusions
Our findings provide relevant information for the standardization of sample collection and storage in the analysis of AD BBM in an automated platform. This knowledge is crucial to ensure their introduction into clinical settings.
Transnational Business Services, Cultural Transformation/Identity, and Employee Performance: With Special Focus on Migration Experience and Emigration Plan
Authors: Kotorri Dushi Arlinda 
Published: April 2023

Abstract
The aim of this article is to analyze the impact of cultural identity centrality on stress, burnout, probability to leave the job, and job performance in the context of cultural transformation requirements, which is common in transnational business services. The key contribution of this analysis consists of controlling for the effects of migration experience and migration plan neglected so far in the relevant literature. This study also includes the first-time use of a random sample of 200 Kosovan call center employees. Findings indicate that individual identity centrality and organizational identity centrality are positively associated with stress and burnout. National identity centrality, however, reduces stress and burnout, but it is statistically significant only in the burnout model. As expected, empirical results suggest that migration experience reduces stress and burnout, while migration plan increases employee performance. Further results indicate that the probability to leave the job is enhanced by perceived job stress and reduced by perceived job satisfaction.
Cognitive biases in internal medicine: a scoping review
Authors: Loncharich Michael F. , Robbins Rachel C. , Durning Steven J. , Soh Michael , Merkebu Jerusalem 
Published: April 2023

Abstract

Background
Medical errors account for up to 440,000 deaths annually, and cognitive errors outpace knowledge deficits as causes of error. Cognitive biases are predispositions to respond in predictable ways, and they don’t always result in error. We conducted a scoping review exploring which biases are most prevalent in Internal Medicine (IM), if and how they influence patient outcomes, and what, if any, debiasing strategies are effective.

Content
We searched PubMed, OVID, ERIC, SCOPUS, PsychINFO, and CINAHL. Search terms included variations of “bias”, “clinical reasoning”, and IM subspecialties. Inclusion criteria were: discussing bias, clinical reasoning, and physician participants.

Summary
Fifteen of 334 identified papers were included. Two papers looked beyond general IM: one each in Infectious Diseases and Critical Care. Nine papers distinguished bias from error, whereas four referenced error in their definition of bias. The most commonly studied outcomes were diagnosis, treatment, and physician impact in 47 % (7), 33 % (5), and 27 % (4) of studies, respectively. Three studies directly assessed patient outcomes. The most commonly cited biases were availability bias (60 %, 9), confirmation bias (40 %, 6), anchoring (40 %, 6), and premature closure (33 %, 5). Proposed contributing features were years of practice, stressors, and practice setting. One study found that years of practice negatively correlated with susceptibility to bias. Ten studies discussed debiasing; all reported weak or equivocal efficacy.

Outlook
We found 41 biases in IM and 22 features that may predispose physicians to bias. We found little evidence directly linking biases to error, which could account for the weak evidence of bias countermeasure efficacy. Future study clearly delineating bias from error and directly assessing clinical outcomes would be insightful.
Recognition, diagnostic practices, and cancer outcomes among patients with unintentional weight loss (UWL) in primary care
Authors: Rao Goutham , Ufholz Kelsey , Saroufim Paola , Menegay Harry , Beno Mark 
Published: April 2023

Abstract

Objectives
Identify the incidence, rate of physician recognition, diagnostic practices and cancer outcomes for unintentional weight loss (UWL).

Methods
We completed a secondary analysis of structured and unstructured EHR data collected from adult patients between January 1, 2020 and December 31, 2021. We used four common definitions to define UWL, excluding patients with known causes of weight loss, intentional weight loss, and pregnancy. Unstructured physicians’ notes were used to identify both intentional weight loss (e.g. dieting) as well as physician recognition of UWL. Cancer outcomes were identified within 12 months of UWL using diagnostic codes. Physician actions (lab tests, etc.) in response to UWL were identified through manual chart review.

Results
Among 29,494 established primary care patients with a minimum of two weight measurements in 2020 and in 2021, we identified 290 patients who met one or more criteria for UWL (1 %). UWL was recognized by physicians in only 60 (21 %). UWL was more common and more likely to be recognized among older patients. Diagnostic practices were quite variable. A complete blood count, complete metabolic profile, and thyroid stimulating hormone level were the three most common tests ordered in response to UWL. Five patients were diagnosed with cancer within 12 months of UWL (3 in whom UWL was recognized; two in whom it was not.)

Conclusions
Unintentional weight loss is poorly recognized across a diverse range of patients. A lack of research-informed guidance may explain both low rates of recognition and variability in diagnostic practices.

Authors: Murdock H. Moses , Ehrie Jarrod , Bennett Nadia L. , Kogan Jennifer R. 
Published: April 2023

Abstract

Objectives
Describe medical student perspectives on framework learning and develop a free, online, mobile-friendly framework website.

Methods
Internal medicine clerkship students were surveyed at a single U.S. medical school regarding how they learn frameworks. We used Draw.io to create frameworks, which were edited by expert clinicians. Frameworks were hosted online through an academic server, and Google analytics was used to track website activity.

Results
Most medical students report learning frameworks from attending clinicians. We developed 87 frameworks on the “Penn Frameworks’’ website, which was visited by 9,539 unique users from 124 countries over three years.

Conclusions
Most medical students perceive that they learn frameworks during clinical rotations from attending clinicians. We found that it is feasible to develop a low-cost, expert-curated, mobile-friendly resource to supplement in-person learning.

Published: April 2023

Abstract
A series of novel quinazoline derivatives bearing sulfonamide moiety was designed and synthesized, and their structure were characterized by 1H NMR, 13C NMR, and HRMS techniques. Among them, the structure of compound E1 was further confirmed through X-ray single-crystal diffraction analyses. Their anti-Tobacco mosaic virus (TMV) activities were evaluated through half-leaf method. The bioassay results showed that E8 and E19 possess excellent inhibitory activity towards TMV. The EC50 of curative activities, protective activities, and inactivating activities of E8 and E19 are 132.1, 152.8, 57.4 mg/L and 278.0, 165.3, 94.5 mg/L, respectively, which are far superior than Ribavirin (318.2, 201.5, 128.6 mg/L, respectively).

Published: April 2023

Abstract
Cervical cancer is a typical cancer characterized by abnormal cell growth in the cervical area. Ginkgo biloba L. is a deciduous tree of the genus Ginkgo, possessing anti-cancer effects. The aim of this study was to explore the effect of strain J1 from Ginkgo biloba L. on apoptosis of cervical cancer cells. Bacteriostatic activity test, MTT assay and Flow cytometry were used in this study. Crude extract of J1 fermentation reduced cell growth in cervical cancer. The crude extract of the fermentation broth of strain J1 had a good inhibitory effect on Staphylococcus aureus. The crude extract of the J1 fermentation had no toxic effect on normal WISH cells in the range of anti-cervical cancer concentration. Crude extract of J1 fermentation induced apoptosis and regulated cell cycle in cervical cancer. The active compounds were separated and identified by preparative chromatography, and more than ten compounds were obtained. Our study suggests that the crude extract of J1 fermentation from Endophytic fungi of Ginkgo biloba reduced cell growth, and promoted apoptosis of cervical cancer, and is a potential therapeutic strategy for the treatment of cervical carcinoma.
Is a Secondary Currency Essential? – On the Welfare Effects of a New Currency
Authors: Fuchs Max , Michaelis Jochen 
Published: April 2023

Abstract
The coexistence of fiat money (cash) and digital monies constitutes a system of parallel currencies as media of exchange. This paper asks whether a new (digital) currency is essential: Does a new currency allow for a better resource allocation even if a fully accepted currency is in circulation and remains in circulation? Using the dual currency search model of Kiyotaki and Wright (1993. A search-theoretic approach to monetary economics. Am. Econ. Rev. 83: 63–77), we show how the introduction of a secondary currency affects average utility. There is some scope for a welfare improvement as the welfare effect depends on differences in returns and costs, and, in particular, on the proportion of cash traders who will be replaced by digital money traders.
