Published: January 2025

Abstract
Recent advancements in quantum technology have highlighted the potential of nitrogen-vacancy (NV) centers in diamond. However, fully realizing this potential requires addressing challenges related to the size, complexity, and cost of current optical systems used for NV center manipulation. In this work, we present a compact and portable confocal setup specifically designed for the efficient detection and control of single NV centers. Our system facilitates optical initialization and readout of individual NV center photoluminescence signals, enabling coherent spin control and nanoscale-resolution magnetic field sensing.

BACKGROUND:
Proficiency in endotracheal intubation (ETI) is essential for medical professionals and its training should start at medical schools; however, large caseload may be required before achieving an acceptable success rate with direct laryngoscopy. Video laryngoscopy has proven to be an easier alternative for intubation with a faster learning curve, but its availability in medical training may be an issue due to its high market prices. We devised a low-cost 3-dimensionally printed video laryngoscope (3DVL) and performed a randomized trial to evaluate if the intubation success rate on the first attempt with this device is noninferior to a standard commercially available video laryngoscope (STVL).

METHODS:
Two hundred and nine medical students from 5 medical schools were enrolled and randomized to start with the STVL (McGrath MAC) or the 3DVL. Four stations (standard airway using the STVL/3DVL and difficult airway using the STVL/3DVL) were set to simulate ETI with standard Airway Management Trainer manikins (Laerdal Medical Ltd.). The noninferiority margin of 7.5% was defined for the success rate on the first attempt, considering the difference in proportions between the STVL (expected to be higher) and 3DVL groups.

RESULTS:
Regarding the standard airway station, 60.7% (n = 65) of the students successfully performed TI on the first attempt with the STVL within the established timeframe, compared to 36.3% (n = 37) of the students using the 3DVL. This represented a difference of 24.4% (95% confidence interval, 17.5%–31.3%). Considering the difficult airway station, the success rates on the first intubation attempt with the 2 VLs did not differ.

CONCLUSIONS:
The 3DVL was inferior in achieving first-attempt intubation when compared with the STVL with a difference in success rate >7.5% margin in simulated scenarios with medical students. Tracheal intubation might require a set of psychomotor skills for which the McGrath MAC device is superior to the low-cost alternative.
An in vivo CRISPR screen in chick embryos reveals a role for MLLT3 in specification of neural cells from the caudal epiblast
Authors: Libby Ashley R. G , Rito Tiago , Radley Arthur , Briscoe James 
Published: January 2025

ABSTRACT
Tissue development relies on the coordinated differentiation of stem cells in dynamically changing environments. The formation of the vertebrate neural tube from stem cells in the caudal lateral epiblast is a well-characterized example. Despite an understanding of the signalling pathways involved, the gene regulatory mechanisms remain poorly defined. To address this, we developed a multiplexed in vivo CRISPR screening approach in chick embryos targeting genes expressed in the caudal epiblast and neural tube. This revealed a role for MLLT3, a component of the super elongation complex, in the specification of neural fate. Perturbation of MLLT3 disrupted neural tube morphology and reduced neural fate acquisition. Mutant forms of retinoic acid receptor A lacking the MLLT3 binding domain similarly reduced neural fate acquisition. Together, these findings validate an in vivo CRISPR screen strategy in chick embryos and identify a previously unreported role for MLLT3 in caudal neural tissue specification.
Chronic bacterial infections exert metabolic costs in Drosophila melanogaster
Authors: Darby Andrea M. , Keith Scott A. , Kalukin Ananda A. , Lazzaro Brian P. 
Published: January 2025

ABSTRACT
Bacterial infections can substantially impact host metabolic health as a result of the direct and indirect demands of sustaining an immune response and of nutrient piracy by the pathogen itself. Drosophila melanogaster and other insects that survive a sublethal bacterial infection often carry substantial pathogen burdens for the remainder of life. In this study, we asked whether these chronic infections exact metabolic costs for the host, and how these costs scale with the severity of chronic infection. We infected D. melanogaster with four bacterial species (Providencia rettgeri, Serratia marcescens, Enterococcus faecalis and Lactococcus lactis) and assayed metabolic traits in chronically infected survivors. We found that D. melanogaster carrying chronic infections were uniformly more susceptible to starvation than uninfected controls, and that sensitivity to starvation escalated with higher chronic pathogen burden. We observed some evidence for greater depletion of triglyceride and glycogen stores in D. melanogaster carrying chronic bacterial loads, although this varied among bacterial species. Chronically infected flies exhibit sustained upregulation of the immune response, which we hypothesized might contribute to the metabolic costs. Consistent with this prediction, genetic activation of the major innate immune signaling pathways depleted metabolic stores and increased starvation sensitivity even in the absence of infection. These results demonstrate that even sublethal infections can have substantial health and fitness consequences for the hosts, arising in part from pathogen-induced immune activation, and that the consequences scale quantitatively with the severity of infection.

Published: January 2025

Background
Rigorous population-based assessments of the use of specialty palliative care (SPC) in the US are rare.

Settings/subjects
This study examined SPC use among cancer patients in a mid-sized metropolitan area in Southeast US.

Measurements
In this cancer decedent cohort study, data were acquired and linked from the state-wide cancer registry; state-wide hospital discharge dataset; and local SPC providers.

Results
12,030 individuals with cancer were included in this study; only 2,958 (24.6%) used SPC. Of the 9,072 persons who did not use SPC, 3,877 (42.7%) went only to hospitals that did not offer SPC; and 3,517 (38.8%) went to hospitals that offered SPC but did not use it. About half of SPC recipients (1493; 50.5%) first received SPC in the final 30 days of life, including 768 (26.0%) in the final week of life. Characteristics associated with using SPC use included being in an socio-economic status quintile other than the lowest; being younger; being Black; having a solid (versus hematological) cancer; having a shorter survival with cancer; dying in the latter two years of the study; being from an area of low or complete rurality; having a hospital admission in the final 60 days prior to initiation of PC or death; having more days in hospital; and living within 15 miles of a hospital offering SPC.

Conclusions
In this population-based study, only one-quarter of cancer patients used SPC, and for half who did so, it came in the final 30 days of life.

Introduction
Respiratory syncytial virus (RSV) is the leading cause of hospitalization among US infants. Characterizing service utilization during infant RSV hospitalizations may provide important information for prioritizing resources and interventions.

Objective
The objective of this study was to describe the procedures and services received by infants hospitalized during their first RSV episode in their first RSV season, in addition to what proportion of infants died during this hospitalization.

Methods
In this retrospective observational study, we analyzed three different administrative claims datasets to examine healthcare service utilization during RSV hospitalizations among infants. The study population included infants born between July 2016 and February 2020 who experienced an RSV episode during their first RSV season and had an associated inpatient hospitalization. We stratified infants into three comorbidity groups: healthy term, palivizumab-eligible, and other comorbidities. Outcomes included extracorporeal membrane oxygenation, supplemental oxygen use (in-hospital and post-discharge), mechanical ventilation (invasive and non-invasive), chest imaging, infant mortality, length of inpatient stay, intensive care unit (ICU) admission, and number of days in the ICU.

Results
Chest imaging was the most frequently administered procedure during RSV-associated hospitalizations, with approximately 34–38% of infants receiving it. Around one-quarter of infants were admitted to the ICU during their first RSV hospitalization. Median lengths of stay in the hospital were 3–4 days, extending to 4–6 days in the presence of ICU admission. Palivizumab-eligible infants had higher utilization of healthcare services and spent more time in the hospital or ICU compared to healthy infants or those with other comorbidities.

Conclusions
This study provides insights into the utilization of healthcare services during RSV hospitalizations among infants. Understanding service utilization patterns can aid in improved management and resource allocation for infants in the United States, ultimately contributing to better outcomes and reduced healthcare costs overall. However, likely under-ascertainment of ventilation and oxygen-related services in insurance claims remains an impediment to studying these outcomes.

INTRODUCTION:
Disorders of gut-brain interaction, such as functional dyspepsia (FD), are prevalent and challenging conditions. In other gastrointestinal (GI) disorders, individuals from underserved areas (UAs) have difficulty accessing care. Little is known about UA FD patient perspectives of their care, especially in those with limited English proficiency. We aimed to characterize patients' experiences with FD management with the goal of informing future studies targeting disorders of gut-brain interaction management in potentially vulnerable communities residing in UAs.

METHODS:
Participants meeting FD criteria were identified in 2 community health centers affiliated with a large academic medical center in the Northeastern United States. Semistructured interviews were conducted in English and Spanish. Transcripts were reviewed by a bilingual panel of investigators using the constant comparative method of iterative data acquisition. Psychosocial stressors and GI symptom severity were assessed.

RESULTS:
A total of 26 participants were interviewed (12 English-speaking and 14 Spanish-speaking). Broadly, GI symptoms were mild and there was mild-to-moderate psychological distress present. Adverse social determinants of health were highly prevalent. Despite mild symptom severity on objective scales, FD severely affected quality of life and interfered with physical, psychological, and social well-being, including avoidance of certain foods and professional/social situations. Study participants (particularly those with limited English proficiency status) reported difficulty in receiving care. Thematic saturation was achieved.

DISCUSSION:
Even when symptoms were mild, interviewees from UAs reported significant FD-related impairment, along with psychological distress. Education interventions targeting FD-related care in UAs should be designed to improve shared decision making in FD, sensitive to the burden of social determinants of health.

In the field of comparative historical linguistics, examining language kinship can illuminate the relationships between languages in a particular region and their evolutionary paths over time. Sundanese and Balinese are two prominent languages that originated in different areas of Indonesia, yet both are part of the Austronesian language family. This study aims to investigate the kinship relationship between Sundanese and Balinese by employing lexicostatistics and phonemic correspondence techniques, providing a structured approach to analyzing their linguistic connections. Data collection was conducted through interviews, focusing on 200 Swadesh vocabulary words that encompass basic terms. The findings reveal a kinship degree of 41% between Sundanese and Balinese, indicating that they diverged approximately 2,058 years ago. Several phonemic correspondences were identified, including /a ~ ə/, /ɣ ~ ə/, /d~ r/, and /a,u/ ~ o/. The analysis further unveiled sound change processes such as lenition, merger, and splitting. Notably, Sundanese appears to be more closely aligned with Proto-Austronesian (PAN) than Balinese, as it has preserved certain phonemes, including /b/, /d/, and /h/, without significant alterations. These findings support the conclusion that Sundanese and Balinese belong to the same language family classification.
Izbira habitata evropskega bobra <i>Castor fiber </i>(Rodentia: Castoridae) na Goričkem (severovzhodna Slovenija)
Authors: Kološa Laura , Janžekovič Franc , Klenovšek Tina 
Published: January 2025

Evropski bober je v Sloveniji in večjem delu Evrope v začetku 20. stoletja veljal za izumrlo vrsto. Ob koncu 20. stoletja se je po številnih reintrodukcijah in uveljavitvi ohranitvenih ukrepov ponovno razširil. V Sloveniji se je vnovič naselil leta 1998, na Goričkem leta 2016. V zimi 2021/22 smo na Goričkem popisali šest vodnih teles, na katerih je bilo med letoma 2016 in 2020 potrjeno pojavljanje te vrste. Namen popisa je bil ugotoviti značilnosti bobrovega habitata na Goričkem glede na ključne okoljske dejavnike, ki mu omogočajo preživetje. Zaradi zgodnje faze naselitve smo domnevali, da je bober za svoj teritorij izbral optimalne habitate. Na izbranih odsekih vodnih teles smo popisali 82 ploskev. Aktivnost bobra je bila potrjena na 71 % ploskev s stoječo in 26 % ploskev s tekočo vodo. Najpogostejši tip kopenskega habitata so bile njive. Gozd je pokrival le 18 % ploskev. Bober je bil najpogosteje zabeležen prav na ploskvah z gozdom (73 %). Brežine vodnih teles so bile v glavnem zelo strme (> 60°). Sledovi bobra so bili najpogosteje najdeni na brežinah z višino do vključno 1 m, naklonom 30˚–60˚ in povprečno 500 m oddaljenostjo od naselij. Vodotoki, ki jih je na Goričkem naselil bober, so razmeroma ozki in plitki, a jih bober kljub temu naseljuje. Najpomembnejši okoljski dejavnik za bobre je razpoložljivost ustrezne lesne vegetacije, s katero se hrani predvsem jeseni in pozimi. Poznavanje značilnosti in izbire habitata je pomembno za varstveno upravljanje in monitoring bobra na Goričkem in v Sloveniji.

Profit and Reliability Analysis of a Gas Production Unit with the Concept of Optimal Age Replacement Policy: A Copula Approach
Authors: Sengar Surabhi 
Published: January 2025

Abstract
This paper presents a comparative study of reliability analysis of a gas production plant, before and after applying optimal age replacement policy for a specific machine. The gas production plant has six machines connected in the series configuration a sulfur (S) shaft, coal pit, reaction furnace, sulfur separation machine, adiabatic reactor, and cooling machine. Here, the optimal age replacement policy has been applied to the cooling machine as this machine is working under a wear-out period, i.e., it has completed its prescribed age (say T) and is still operational. Two different situations have been discussed to analyze the performance variation of the system (i) when the model is working with high risk because the cooling machine is operational even after completion of its prescribed age (ii) when the old cooling machine is replaced by a new one after completing the age, T. The failure of any machine can cause the model failure. Additionally, a situation of employee walkout is also considered a responsible factor for model failure. Supplementary variable technique and copula methodology have been applied to solve the Markov model.

Published: January 2025

Abstract
Obstructive Sleep Apnea (OSA) is a prevalent sleep disorder marked by repeated episodes of partial or complete upper airway obstruction during sleep, which leads to intermittent hypoxia and fragmented sleep. These disruptions negatively impact cardiovascular health, metabolic function, and overall quality of life. Obesity is a major modifiable risk factor for OSA, as it contributes to both anatomical and physiological mechanisms that increase the likelihood of airway collapse during sleep. While continuous positive airway pressure (CPAP) therapy remains the gold standard for OSA treatment, its limitations – particularly issues with patient adherence – underscore the need for alternative or adjunct therapeutic options. One such option is the use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs), which are widely recognized for their ability to reduce body weight and improve metabolic health. Emerging evidence suggests that GLP-1 RAs may offer therapeutic benefits in managing OSA, particularly by addressing obesity, a key contributor to the condition. This narrative review seeks to explore the role of GLP-1 RAs in the treatment of OSA, evaluating their efficacy in reducing OSA severity and discussing their broader clinical implications for future research and practice.
On the solvability of an inverse problem for the Burgers equation with an integral overdetermination condition in a nonlinearly degenerating domain

Published: January 2025

Abstract
The paper considers an inverse problem and a direct problem for the Burgers equation in a domain with movable boundaries. With the help of an additional condition, a formula is obtained for determining the desired function from a direct problem for the loaded Burgers equation for the solvability of which we require a condition on the functions according to which the boundaries of the domain change. The solvability of direct problems is proved using a priori estimates and the methods of Faedo–Galerkin and functional analysis.
