BACKGROUND

The Ministry of Health in Côte d'Ivoire and the International Training and Education Center for Health at the University of Washington, funded by the United States President’s Emergency Plan for AIDS Relief, have been collaborating to develop and implement the Open-Source Enterprise-Level Laboratory Information System (OpenELIS). The system is designed to improve HIV-related laboratory data management and strengthen quality management and capacity at clinical laboratories across the nation.

OBJECTIVE

This evaluation aimed to quantify the effects of implementing OpenELIS on data quality for laboratory tests related to HIV care and treatment.

METHODS

This evaluation used a quasi-experimental design to perform an interrupted time-series analysis to estimate the changes in the level and slope of 3 data quality indicators (timeliness, completeness, and validity) after OpenELIS implementation. We collected paper and electronic records on clusters of differentiation 4 (CD4) testing for 48 weeks before OpenELIS adoption until 72 weeks after. Data collection took place at 21 laboratories in 13 health regions that started using OpenELIS between 2014 and 2020. We analyzed the data at the laboratory level. We estimated odds ratios (ORs) by comparing the observed outcomes with modeled counterfactual ones when the laboratories did not adopt OpenELIS.

RESULTS

There was an immediate 5-fold increase in timeliness (OR 5.27, 95% CI 4.33-6.41; P<.001) and an immediate 3.6-fold increase in completeness (OR 3.59, 95% CI 2.40-5.37; P<.001). These immediate improvements were observed starting after OpenELIS installation and then maintained until 72 weeks after OpenELIS adoption. The weekly improvement in the postimplementation trend of completeness was significant (OR 1.03, 95% CI 1.02-1.05; P<.001). The improvement in validity was not statistically significant (OR 1.34, 95% CI 0.69-2.60; P=.38), but validity did not fall below pre-OpenELIS levels.

CONCLUSIONS

These results demonstrate the value of electronic laboratory information systems in improving laboratory data quality and supporting evidence-based decision-making in health care. These findings highlight the importance of OpenELIS in Côte d'Ivoire and the potential for adoption in other low- and middle-income countries with similar health systems.

Heart failure (HF) is a severe cardiovascular disease that poses significant challenges to global health. Recently, the application of artificial intelligence (AI) techniques in the field of heart failure has gained widespread attention and demonstrated immense potential. This study aims to provide a step-by-step guide for clinicians and researchers on the practical application of AI techniques in the domain of heart failure, with the objective of enhancing the transparency and applicability of these methods. The workflow for AI applications in heart failure starts with data selection and preprocessing. Here, we outlined the relevant preprocessing steps and machine-learning algorithm choices based on the type of data (structured, unstructured, or time series). Emphasizing the importance of model validation, we highlighted the need for an objective performance evaluation. Furthermore, by focusing on the integration of AI techniques in heart failure management, we actively addressed the concept of the ‘three levels of prevention’. The three levels of prevention involve interventions that aim to minimize complications and improve outcomes in patients with established heart failure. In this study, we presented five case studies that represent different applications of AI in the field of heart failure, illustrating how AI can assist in risk stratification, personalized treatment planning, and prognostic assessments. These case studies improve the readers' understanding of the underlying principles of AI and its potential role in implementing three levels of prevention strategies. However, it is crucial to acknowledge the limitations of the data sources, select appropriate machine learning algorithms, and conduct comprehensive evaluations and validations when utilizing AI technologies. By adhering to these methods, we can enhance the accuracy and generalizability of AI in clinical applications for heart failure. This has the potential to improve the quality of care for patients with HF and reduce the burden of disease.

UNSTRUCTURED

Prompt engineering is a relatively new field of research that refers to the practice of designing, refining, and implementing prompts or instructions that guide the output of large language models (LLMs) to help in various tasks. With the emergence of LLMs, the most popular one being ChatGPT that has attracted the attention of over a 100 million users in only 2 months, artificial intelligence (AI), especially generative AI, has become accessible for the masses. This is an unprecedented paradigm shift not only because of the use of AI becoming more widespread but also due to the possible implications of LLMs in health care. As more patients and medical professionals use AI-based tools, LLMs being the most popular representatives of that group, it seems inevitable to address the challenge to improve this skill. This paper summarizes the current state of research about prompt engineering and, at the same time, aims at providing practical recommendations for the wide range of health care professionals to improve their interactions with LLMs.

La espectroscopia de reflectancia en el infrarrojo cercano (NIRS) permite estimar la composición química de diversas muestras, (ingredientes, productos de origen animal, etc.); sin embargo, existe poca información de su uso con muestras de digesta ileal (DI) o heces (H) de cerdo; por lo que el objetivo fue desarrollar ecuaciones de predicción basadas en el método de cuadrados mínimos parciales para predecir la composición química de DI y H a través de un NIRS. Se utilizaron 110 muestras de DI y 202 de H de experimentos de digestibilidad, obteniéndose su espectro y mediante un modelo multivariado se desarrolló el método de predicción. Las variables analizadas en la DI fueron: proteína cruda (PC), Leucina (Leu), lisina (Lys) y treonina (Thr) y en las H: materia seca (MS), PC y energía (E). Los valores en DI fueron: PC: R2 0.98, error estándar de calibración (SEC) 0.330, error estándar de predicción (SEP) 0.640; Leu: R2 0.95, SEC 0.040, SEP 0.102; Lys: R2 0.93, SEC 0.077, SEP 0.143; Thr: R2 0.67, SEC 0.209, SEP 0.187. En H fueron PC: R2 0.98, SEC 0.95, SEP 1.19; E (kcal/kg): R2 0.94, SEC 60.8, SEP 95.3; MS: R2 0.87, SEC 0.83, SEP 1.15. Los resultados muestran que la robustez de la calibración (DE/SEP) fue buena para PC, 3.34, Leu 2.07 y Lys 2.48 y regular para Thr 1.94, la predicción (RPD) fue buena para PC 2.11 en la DI. En H las R2 fueron altas para PC 0.98 y E 0.94. La mayor robustez fue para PC 5.59 y su predicción fue excelente 4.16 y buena para E 2.53. Se concluye que el NIRS puede predecir la PC en la DI y la PC y E en H. Para mejorar la estimación de aminoácidos en DI deben explorarse las causas que afectan la robustez de las calibraciones.

El objetivo del estudio fue comparar el efecto de dispositivos intravaginales liberadores de progesterona natural (CIDR) nuevos y reutilizados en protocolos de 6 días sobre el desempeño reproductivo y en las concentraciones de progesterona en suero sanguíneo de ovejas multíparas. Un total de 172 ovejas con peso corporal promedio de 59 kg se distribuyeron al azar en cuatro tratamientos: CIDR1 (grupo testigo con dispositivos nuevos) y CIDR2, CIDR3, CIDR4 (con 6, 12 y 18 días de uso, respectivamente). En cuanto al inicio de estro, hubo diferencia (P≤0.05) únicamente entre el tratamiento con CIDR nuevos (40 ± 10 h) y CIDR de segundo uso (31 ± 9 h). En las variables presencia de estro, porcentaje de gestación, porcentaje de fertilidad y tipo de parto no se obtuvieron diferencias significativas (P>0.05) entre tratamientos. La presencia de estro osciló entre 93 y 100 %, el valor promedio de gestación fue 80.8 %, 80.2 % para fertilidad y 1.26 para el índice de prolificidad. Los porcentajes de partos sencillos fueron mayores (P≤0.05) a los partos dobles en los cuatro tratamientos. Se concluye que el uso de CIDR en protocolos de 6 días permite que los dispositivos sean utilizados hasta por cuatro ocasiones con buenos resultados.

Published: July 2023

Actualmente el sistema de construcción para las casas de habitación es el bloque de hormigón, el cual tiene un peso aproximado de entre 17,6 kg por pieza y cuyo diseño es difícil de manejar y complejo de colocar paraque la estructura de la construcción quede en óptimas condiciones. Adicionalmente, los materiales que componen el hormigón tienen un impacto ambiental negativo pues la explotación de arena, la fabricación de cemento y el agua utilizada presentan varios impactos ambientales, considerados como no sostenibles. Debido a lo anterior, los productos dirigidos a la construcción se tienen que innovar mediante la reutilización o reciclaje de materiales que funcionen como agregados para la fabricación de estos bloques de construcción, de tal forma que mejoren las especificaciones técnicas del bloque, que alarguen su vida útil y cuyo diseño físico permita realizar una instalación o colocación en menor tiempo y de forma sencilla. Por esta razón se propone el diseño conceptual y prototipado rápido a escala de un bloque deconstrucción para casas de habitación un enfoque innovador, haciendo uso de herramientas de ecodiseño, conceptos de la metodología TRIZ y del análisis de ciclo de vida (ACV). El resultado de este trabajo es la propuesta de rediseño de un bloque deconstrucción que considera la integración de la forma, función y materiales, mejorando las características del bloque de hormigón actual, disminuyendo sus desventajas y su impacto ambiental negativo, mediante prototipos a escala que validan su función y diseño.

Published: July 2023

We investigated the development of water-in-oil (W/O) emulsions just
using CW, evaluating the effect of the water to CW oleogel ratio (40:60,
50:50, 60:40) and, at each ratio, the effect of the CW concentrations
(0.75% to 3%). The emulsions were developed by shearing (60 s at 25°C)
using an ultra-turrax type homogenizer. The emulsions were immediately
evaluated and after 20 days of storage (25°C) for microstructure, water
droplet diameter, emulsion stability through DSC freeze/thaw cycles,
rheological properties, and X-ray measurements. The results showed that,
at all water to oleogel ratios studied the CW developed structured W/O
emulsions where the surface-active components of the CW (i.e.,
triterpenic alcohols, aliphatic alcohols, and fatty acids) stabilized
the oil-water interface, while the n-alkanes and long chain esters
formed an oleogel in the oil phase. Although, independent of the storage
time, all the CW emulsions showed a frequency independent rheological
behavior, after applying a strain above the G’-G” cross point, the
40:60 and 50:50 emulsions with 1.5% to 3% CW concentration showed the
better rheological behavior and were the most stables, even after two
freeze-thaw cycles. In particular, the 40:60 and 50:50 emulsion with
1.5% CW had a recovery profile similar to commercial mayonnaise. In
contrast, independent of the CW concentration, the 60:40 emulsions
showed the lowest recovery profiles and higher instability to
freeze-thaw cycles. These results indicated that the CW is a
multi-functional material able to develop structured W/O emulsions
useful for the formulation of trans-free, stable low-fat edible spreads.

Published: July 2023

Introduction: Erdheim-Chester Disease (ECD) is a rare non-Langerhans
cell histiocytic disorder, first described in 1930. Its diverse
manifestations range from asymptomatic bone lesions to severe systemic
involvement. Herein, we report a novel case of ECD presenting with
temporal bone pain, a symptom not previously described in the
literature. Methods: We observed and analyzed the symptoms, clinical
history, and imaging manifestations of a patient presenting with
significant temporal bone pain. The diagnosis was confirmed via a
biopsy. We also investigated the presence of the BRAFV600E mutation,
which is known to be present in over half of ECD cases. Results: The
patient presented with significant temporal bone pain on pressure but
exhibited no clinical signs of urinary collapse or neurological
symptoms. Imaging studies showed typical signs of ECD, and a biopsy
confirmed the diagnosis. Genetic testing revealed the presence of the
BRAFV600E mutation. Conclusion: This case extends our understanding of
the clinical manifestations of ECD and highlights the potential for
variable symptomatology. Temporal bone pain may be a novel presentation
of ECD, emphasizing the need for a high index of suspicion and thorough
evaluation in patients presenting with unexplained bone pain. The
confirmation of the BRAFV600E mutation in this patient underlines its
potential as a therapeutic target in ECD. Future research is necessary
to fully elucidate the clinical significance and treatment implications
of this novel presentation.

Vaccination against coronavirus disease 2019 (COVID-19) in Spain began
in the year 2020, starting by groups with high exposure, including
biomedical students with clinical practices. It is suggested that these
students could have a lower incidence of COVID-19 than other students of
the same age group due to early vaccination, different exposure, and
disease awareness. A cross-sectional observational study was conducted
through a questionnaire distributed in February 2022. 536 people
answered the questionnaire and 53 were excluded, making 483 evaluable
(320 biomedical and 163 non-biomedical), 73.71% women, 98.55%
vaccinated and 52.59% never infected. 67.81% of biomedical students
had clinical practices. No differences were found in the incidence
between biomedical and non-biomedical students (54.06% versus 53.99%,
p=0. 952); nor when classifying it specifically by periods, although
there is a tendency towards significance in the third (July
2021-November 2021) period (9.20% non-biomedical and 4.38% biomedical,
p=0.051). The students receiving the vaccine earlier than their age
group have a lower incidence in this period (2.90% vs 8.18%, p=0.014).
The booster dose reduced the incidence during period 4 (24% versus
34.4%, p=0.017). These data suggest that biomedical students are not at
increased risk for COVID-19, but that early vaccination reduces the
incidence of infection.

Published: July 2023

Background: In clinical experience, the adverse events of alprostadil
are widely acknowledged; However, there remain adverse reactions that go
unnoticed. Methods: In order to evaluate the imbalance of adverse events
associated with alprostadil in real-world data, four algorithms (ROR,
PRR, BCPNN, and EBGM) were utilized as metrics to identify signals of
adverse events linked to alprostadil. Results: In this study, a total of
13,703,053 reported cases were collected from the FAERS database during
the study period (from the third quarter of 2014 to the second quarter
of 2023). 2393 case reports were analyzed after the exclusion of
duplicates and identified using four algorithms. Among these cases, 725
AEs were identified, of which 119 were found to be ADRs related to
alprostadil as the primary suspect drug. The observed adverse effects of
alprostadil, including hypokalemia and pain, were discovered.
Additionally, other noted adverse effects were identified, indicating a
condition that is not mentioned in the package insert. Conclusion: This
study has discovered previously unknown indicators of adverse drug
reactions linked to alprostadil, offering valuable understanding into
the correlation between adverse drug reactions and the usage of
alprostadil. The results emphasize the potential negative effects
arising from alprostadil usage, as well as the potential harm resulting
from incorrect administration operation, ultimately enhancing patient
safety throughout alprostadil treatment.
Large-Scale Chiral Spherulites with Controllable Circularly Polarized Luminescence in Liquid Crystal Block Copolymers Film
Authors: Yuan Jianan , Lu Xuemin , Lu Qinghua
Published: July 2023

Macroscopic chiral spherulites prepared by hierarchical self-assembly
have attracted considerable attention due to their excellent property as
chiroptical materials. However, preparing controllable handedness
spherulites in bulk film remains a challenge due to the absent knowledge
of the evolution mechanism from the molecule to macroscopic crystal
during chiral assembly. In this contribution, we constructed chiral
controllable macroscopic spherulites with circularly polarized
luminescence (CPL) using enantiomeric tartaric acid and Rhodamine B
co-assembled with liquid crystal block copolymers, poly (ethylene
oxide)-b-poly (methyl methacrylate) bearing azobenzene group side
chains. It was found that the chiral liquid crystal field induced by
exogenous chiral molecules was closely related to the formation of
macroscopic chiral spherulites. Moreover, the transformation of
azobenzene cis-trans isomerization under photo-thermal endows films with
adjustable CPL. This facile strategy provides a platform to design
large-scale chiral structures for chiroptical switching, encryption, and
memory storage materials.

During a prospective multicenter non-interventional observational study, a comparative assessment was made of the serotype structure of pneumococci circulating among healthy children under the age of 5 years and children of the same age group with signs of respiratory infections in the periods 2016-2018 and 2020-2022. Data on the serotype structure of pneumococci in the period from 2016-2018 were obtained from our previous works. In 2020-2022 the study included 2066 healthy children and 603 children with respiratory infections. Streptococcus pneumoniae and their DNA were detected in nasopharyngeal swabs by classical culture and molecular methods. Typing was carried out by molecular methods. On the territory of the Russian Federation, pneumococci belonging to the serotypes included in the 13-valent vaccine are being forced out of circulation and replaced by non-vaccine serotypes. Before the introduction of mass antipneumococcal vaccination (until 2015), the 13-valent conjugate vaccine covered from 66.2% to 92% of pneumococci, after the start of mass anti-pneumococcal vaccination in the period 2016-2018, coverage decreased to 57.3%. Between 2020 and 2022, coverage was less than 40%. The main “non-vaccine” serotypes/serogroups circulating in the Russian Federation are 15AF, 11AD, 23A, 9LN and 16F.
To Be or Not To Be: The Nature and Extent of Identity Calculus among Accounting Professors from Underrepresented Backgrounds
Authors: Pencle Nadra , Watts Omar
Published: July 2023

Professors from African American, Latinx, and Native American backgrounds are underrepresented in academia and are therefore ascribed a minority status. They are not the stereotypical professors, and so their experiences are not widely documented. This project uses semistructured interviews to garner an understanding of how underrepresented accounting professors navigate professional life in academia. We mobilize Goffman's (1959)The Presentation of Self in Everyday Life as a frame to analyze our interviews. The study findings reveal the multiple calculated actions that these professors undertake while performing on the frontstage of academia, as well as the disconnect between their frontstage and backstage personas. We extend literature and practice by documenting the frontstage performance's toll on underrepresented minorities (URMs) at all levels of their academic careers in accounting.
Do I Belong? The Impact of Belongingness and Stereotype Threat on Professional Commitment to Accounting
Authors: Bailey Cristina , Loftus Serena , McCoy Sarah Shonka
Published: July 2023

Recent trends in the United States show a downturn in new entrants to the accounting profession, with demand for new graduates exceeding the supply. Attracting and retaining entrants to the accounting profession is necessary to address this shortage. We investigate how perceptions of belonging and stereotype threat, defined as the concern about being negatively stereotyped about social identity, influence accounting students’ commitment to the profession. Results show that belonging perceptions are lower for students who experience stereotype threat. Further, the negative relationship between stereotype threat and professional commitment is mediated by perceptions of belonging. Our findings inform educators seeking to increase students’ commitment to the accounting profession about the important influence of stereotype threat. Our results also inform those interested in the belonging perceptions of students who may experience heightened stereotype threat concerns, such as those identifying with historically underrepresented social groups.

The Differential Timeliness of Stock Price in Incorporating Bad versus Good News and the Earnings-Return Asymmetry
Authors: Cheng Zhuo , Fang Jing , Myers Linda A.
Published: July 2023

The larger association between earnings and contemporaneous returns for negative returns than for positive returns is often attributed to conditional conservatism. We reason that this asymmetry may also be driven by the lack of timeliness with which stock price incorporates bad news relative to good news. Consistent with our reasoning, we show that when stock price incorporates bad news with delay, the asymmetry can exist in the absence of conditional conservatism. This suggests the testable hypothesis that the asymmetry decreases (increases) with factors that facilitate (impede) the incorporation of bad news into stock price. Using stock liquidity to test this hypothesis, we find that the earnings-return asymmetry decreases as stock liquidity increases. Our findings support the view that variation in the earnings-return asymmetry also reflects variation in the quality of the return generation process.

Sezary syndrome with arthropathy. Report of a case
Authors: Furey NL , Furey WW , Yonan TN , Esterly NB.
Published: July 2023

A 65-year-old black female with Sezary syndrome had generalized intractable pruritus, erythroderma, alopecia, onychogryphosis, lumphadenopathy and hepatomegaly. Abnormal lymphocytes with large, convoluted and grooved nuclei (Sezary cells) were identified in the skin and peripheral blood. A striking feature of her disease was severe, deforming arthropathy of the hands and knees, a clinical finding which has been described previously in only one patient with Sezary syndrome. At necropsy no associated lymphoma was found.

Dermatitis herpetiformis in association with treated coeliac disease
Authors: Saikia NK , Morley WN.
Published: July 2023

The paper describes an adult patient with coeliac disease who developed classical dermatitis herpetiformis while receiving a gluten-free diet. The dermatitis is controlled by sulphapyridine but relapses when this is withdrawn, even though the patient continues with the diet, indicating that a gluten-free diet plays little or no part in controlling the skin condition.
