Effective data-driven collective variables for free energy calculations from metadynamics of paths

Published: April 2024

Abstract
A variety of enhanced sampling (ES) methods predict multidimensional free energy landscapes associated with biological and other molecular processes as a function of a few selected collective variables (CVs). The accuracy of these methods is crucially dependent on the ability of the chosen CVs to capture the relevant slow degrees of freedom of the system. For complex processes, finding such CVs is the real challenge. Machine learning (ML) CVs offer, in principle, a solution to handle this problem. However, these methods rely on the availability of high-quality datasets—ideally incorporating information about physical pathways and transition states—which are difficult to access, therefore greatly limiting their domain of application. Here, we demonstrate how these datasets can be generated by means of ES simulations in trajectory space via the metadynamics of paths algorithm. The approach is expected to provide a general and efficient way to generate efficient ML-based CVs for the fast prediction of free energy landscapes in ES simulations. We demonstrate our approach with two numerical examples, a 2D model potential and the isomerization of alanine dipeptide, using deep targeted discriminant analysis as our ML-based CV of choice.

Introduction
Tobacco contributes to the leading causes of morbidity and mortality among persons with human immunodeficiency virus (PWHs). Nonetheless, medications for tobacco use disorder are widely underused, particularly among PWHs. We sought to characterize the extent to which insurance barriers impacted access to medications for tobacco use disorder and, in comparison, to access to antiretroviral therapy (ART).

Methods
This is a secondary analysis of data on individuals enrolled in a randomized clinical trial to address tobacco use involving nicotine replacement therapy and, for some, additionally, varenicline or bupropion. Medication prescriptions are transmitted electronically from the clinic to neighborhood pharmacies. Data sources included participant assessments and intervention visit tracking forms.

Results
Of 93 participants enrolled from September 2020 to July 2021, 20 (22%) were unable to fill or had difficulty filling their nicotine replacement therapy (NRT) prescriptions because of insurance barriers. These fell into 2 broad categories: enrollment in a publicly insured managed care plan in which the pharmacy benefit manager excluded nonprescription NRT and lack of understanding by the pharmacy of the scope of coverage. Of these 20 participants, 5 (25%) were unable to obtain medications at all, and 3 of these participants dropped out of the study. One additional participant paid out-of-pocket to obtain NRT. No participant was denied coverage of ART, bupropion, or varenicline.

Conclusions
Gaps in insurance coverage may result in PWHs receiving ART without simultaneous medical management of their tobacco use. This may undermine the efficacy of antivirals. Mandated insurance coverage of nonprescription NRT may improve the health of PWHs who smoke.

Authors: Ye Ziyin , Li Zhi , Zhong Shiyu , Xing Qichen , Li Kunhang , Sheng Weichen , Shi Xin , Bao Yijun 
Published: April 2024

Background:
Traumatic brain injury (TBI) is a serious public health burden worldwide, with a mortality rate of 20–30%; however, reducing the incidence and mortality rates of TBI remains a major challenge. This study provides a multidimensional analysis to explore the potential breakthroughs in TBI over the past two decades.

Materials and methods:
The authors used bibliometric and Latent Dirichlet Allocation (LDA) analyses to analyze publications focusing on TBI published between 2003 and 2022 from the Web of Science Core Collection (WOSCC) database to identify core journals and collaborations among countries/regions, institutions, authors, and research trends.

Results:
Over the past 20 years, 41 545 articles on TBI from 3043 journals were included, with 12 916 authors from 20 449 institutions across 145 countries/regions. The annual number of publications has increased 10-fold compared to previous publications. This study revealed that high-income countries, especially the United States, have a significant influence. Collaboration was limited to several countries/regions. The LDA results indicated that the hotspots included four main areas: ‘Clinical finding’, ‘Molecular mechanism’, ‘Epidemiology’, and ‘Prognosis’. Epidemiological research has consistently increased in recent years. Through epidemiological topic analysis, the main etiology of TBI has shifted from traffic accidents to falls in a demographically aging society.

Conclusion:
Over the past two decades, TBI research has developed rapidly, and its epidemiology has received increasing attention. Reducing the incidence of TBI from a preventive perspective is emerging as a trend to alleviate the future social burden; therefore, epidemiological research might bring breakthroughs in TBI.
Vonoprazan is Not Inferior to Proton Pump Inhibitors in Bismuth-containing Quadruple Therapy for Helicobacter pylori Eradication
Authors: Cheng Yujie , Yang Lin , Xu Si , Zhang Chong 
Published: April 2024

Objective:
To investigate the efficacy and safety of vonoprazan based bismuth-containing quadruple therapy (VBCQ) in eradicating Helicobacter pylori (Hp).

Materials and Methods:
The VBCQ and the proton pump inhibitor-based bismuth-containing quadruple regimen (PBCQ) were compared by retrieving relevant studies in Pubmed, Embase, Cochrane Library, CNKI, and Wanfang data. Combined analysis was performed with risk ratio (RR) and 95% CI as effect values.

Results:
A total of 10 studies were enrolled, including 7 randomized controlled trials and 3 cohort studies. In intention-to-treat analysis, the eradication rate of VBCQ (89.24%, 1103/1236) was significantly higher than that of PBCQ (84.03%, 1021/1215), with RR = 1.06 (95% CI: 1.03~1.10). In per-protocol analysis, the eradication rates of VBCQ and PBCQ were 92.94% (895/963) and 87.82% (829/944), respectively, with a significant difference (RR = 1.06, 95% CI: 1.03~1.09). Subgroup analysis of study design types shared similar results. VBCQ and PBCQ showed an incidence of adverse reactions of 37.30% (304/815) and 34.94% (282/807), respectively. Significant differences were not found between the two groups (RR = 1.07, 95% CI: 0.96-1.19), nor in subgroup analysis. The good compliance rates in VBCQ and PBCQ groups were 94.32% (216/229) and 95.13% (215/226), respectively, with no significant difference (RR = 0.99, 95% CI: 0.95~1.04).

Conclusion:
VBCQ has a higher eradication rate on Hp than PBCQ, while its adverse reactions and compliance are similar to PBCQ. However, we conservatively believe that in Hp eradication, the VBCQ is not inferior to PBCQ because of the small absolute difference.
A giant ovarian cyst torsion: Case report
Authors: Hongju He 
Published: April 2024

Introduction:
Adnexal torsion (AT) is one of a gynecological condition characterized by an acute abdomen. Clinically, a giant ovarian cyst torsion with a diameter of 30 cm is rare. Therefore, an accurate and timely diagnosis and treatment are important.

Patient concerns:
A 25-year-old unmarried female, presented to the emergency department with intermittent abdominal cramps after a sudden change in position. Considering her symptoms and examination, ultrasound, and magnetic resonance imaging (MRI) results, ovarian cyst torsion was suspected.

Diagnosis:
Giant ovarian cyst torsion.

Interventions:
Surgical intervention with exploratory laparotomy was performed immediately.

Outcomes:
Intraoperatively, we found a 30-cm left ovarian cyst with a clear root. The left fallopian tube, infundibulopelvic ligament, and ovarian ligament were twisted 900 degrees. Finally, the pathological report revealed mucinous cystadenoma.

Conclusion:
Giant ovarian cyst torsion with a diameter of 30 cm is rare. Considering her symptoms and examination, ultrasound, and MRI results, ovarian cyst torsion was suspected. The patient was successfully treated using emergency surgery.

Published: April 2024

Introduction and importance:
Schistosomiasis, a parasitic disease, is caused by blood flukes from the schistosoma genus. Neuroschistosomiasis is the most severe form of schistosomiasis, which occurs when the host’s brain and spinal cord react to the deposition of eggs, leading to neurological symptoms. Neuroschistosomiasis causes various signs and symptoms, such as myelopathy, radiculopathy, and elevated intracranial pressure.

Case presentation:
A 12-year-old child from Ethiopia who presented with progressive weakness in his lower extremities that has been ongoing for 2 months. Alongside the weakness, the patient also experienced tingling sensations and numbness in his lower extremities. Additionally, he had bladder and bowel incontinence. Spinal MRI showed signs suggestive of myxopapillary ependymoma, but the histopathology result showed schistosomiasis. Postoperatively, the patient had a slight improvement in terms of lower extremity weakness (flickering of the digits). However, there was no improvement in his continence ability.

Clinical discussion:
The most common neurological manifestation of Schistosoma mansoni infection is myelopathy, which includes subacute myeloradiculopathy and acute transverse myelitis. The cauda equina and conus medullaris are the areas most frequently affected.

Conclusion:
When spinal schistosomiasis presents itself as a mimicking spinal tumour, it poses a complex clinical challenge that necessitates a comprehensive interdisciplinary approach to ensure accurate diagnosis and effective treatment. It is imperative for healthcare practitioners to enhance their knowledge and awareness of this uncommon parasitic infection, particularly in regions where it is prevalent.
Curricular Mapping
Authors: Laverentz Delois Meyer , Guilkey D. Kathaleen , Johnson Regina (Gina) H. 
Published: April 2024

Background:
A Midwest school of nursing initiated an integrated concept-based curriculum where essential content is taught using exemplars. The specialty courses were integrated to address content overload and the duplication of content with different populations.

Problem:
The faculty wanted to determine if the previous curriculum had been sufficiently integrated into the exemplars and if there were curricular gaps.

Approach:
A curriculum mapping project was conducted to assess the integration of the previous curriculum into the exemplars. Specifically, faculty evaluated exemplars for characteristics of: (1) individuals, (2) health care systems, (3) specialties, (3) nurse characteristics, and (4) interprofessional practice.

Conclusions:
Exemplars in an integrated concept-based curriculum can provide a broad representation of individuals across the life span and settings. Curricular mapping is an assessment tool that can identify curricular gaps and the need for refinement within the curricula to meet current and future directions within the health care environment.
Using Open Educational Practices
Authors: Perry Beth , Ives Cindy , Walsh Pam 
Published: April 2024

Background:
This paper reports on our use of open educational practices (OEPs) with online students in nursing.

Purpose:
Our aim was to provide nurse educators with knowledge about (and examples of) OEPs they could use to enhance student learning and their career satisfaction.

Method:
Using collaborative autoethnography, we probed our open teaching strategies. With Swanson’s middle-range theory of caring as a theoretical framework and thematic analysis of our data set (which included literature annotations, dialogic conversation transcripts, individual reflections, and course evaluations), we uncovered 5 themes relevant to nursing education.

Results:
The themes are student achievement of affective domain learning outcomes, our values as a blueprint for action, alignment of our OEPs and relational pedagogy, mutuality of the experience, and the ongoing process of learning to be an open educational practitioner.

Conclusion:
Using OEPs can help develop skilled and caring nurses.

Published: April 2024

AbstractInteroception, the perception and integration of physiological signals, is a fundamental aspect of self-awareness and homeostasis. While previous work has explored interoceptive processing in relation to the cardiac system, research in the respiratory domain, particularly in relation to brain structure and function, is limited. To address this gap, we utilised a Bayesian psychophysical model to quantify perceptual, metacognitive, and affective dimensions of respiratory interoception in a sample of 207 healthy participants. We also measured individual whole-brain microstructural indices of myelination, myeloarchitecture, and cortical iron using quantitative brain imaging. Voxel-based quantification analyses revealed distinct patterns of cortical microstructure in the insular, cingulate, and primary sensory cortices, which underpin interoceptive perceptual sensitivity and precision. In addition, metacognitive bias was associated with increased myelination of the cingulate cortex and periaqueductal grey, while metacognitive sensitivity correlated with myelination of the midline prefrontal cortex. At an affective level, sensitivity to respiratory resistance was related to the myelination of the primary somatosensory cortex. By revealing specific histological brain patterns tied to individual differences in respiratory interoception, our results uncover the neural pathways that govern perceptual, metacognitive, and emotional facets of interoceptive processing.

ABSTRACTThe treatment landscape for opioid use disorder (OUD) faces challenges stemming from the limited efficacy of existing medications, poor adherence to prescribed regimens, and a heightened risk of fatal overdose post-treatment cessation. Therefore, there is a pressing need for innovative therapeutic strategies that enhance the effectiveness of interventions and the overall well-being of individuals with OUD. This study explored the therapeutic potential of nor-Levo-α-acetylmethadol (nor-LAAM) to treat OUD. We developed sustained release nor-LAAM-loaded poly (lactic-co-glycolic acid) (PLGA) microparticles (MP) using a hydrophobic ion pairing (HIP) approach. The nor-LAAM-MP prepared using HIP with pamoic acid had high drug loading and exhibited minimal initial burst release and sustained release. The nor-LAAM-MP was further optimized for desirable particle size, drug loading, and release kinetics. The lead nor-LAAM-MP (F4) had a relatively high drug loading (11 wt.%) and an average diameter (19 µm) and maintained a sustained drug release for 4 weeks. A single subcutaneous injection of nor-LAAM-MP (F4) provided detectable nor-LAAM levels in rabbit plasma for at least 15 days. We further evaluated the therapeutic efficacy of nor-LAAM-MP (F4) in a well-established fentanyl-addiction rat model, and revealed a marked reduction in fentanyl choice and withdrawal symptoms in fentanyl-dependent rats. These findings provide insights into further developing long-acting nor-LAAM-MP for treating OUD. It has the potential to offer a new effective medication to the existing sparse armamentarium of products available to treat OUD.

AbstractThere is an urgent need for agents that promote health and regeneration of cells and tissues, specifically to treat diseases of the aging nervous system. Age-associated nervous system degeneration and various diseases are driven by many different biochemical stresses, often making it difficult to target any one disease cause. Our laboratory has previously identified DNA aptamers with apparent regenerative properties in murine models of multiple sclerosis by selecting aptamers that bind oligodendrocyte membrane preparations. Here, we screened vast libraries of molecules (∼1014unique DNAs) for the ability to bind cultured human SH-SY5Y neuroblastoma cells as model neurons to demonstrate the feasibility of identifying biologically active aptamers by cycles of cell selection. Many of these DNA aptamers bind undifferentiated and differentiated cultured SH-SY5Y cells. Several of these aptamers modulate the biological activity of SH-SY5Y cells upon treatment in culture.

Published: April 2024

AbstractNumber sense is essential for early mathematical development but it is compromised in children with mathematical disabilities (MD). Here we investigate the impact of a personalized 4-week Integrated Number Sense (INS) tutoring program aimed at improving the connection between nonsymbolic (sets of objects) and symbolic (Arabic numerals) representations in children with MD. Utilizing neural pattern analysis, we found that INS tutoring not only improved cross-format mapping but also significantly boosted arithmetic fluency in children with MD. Critically, the tutoring normalized previously low levels of cross-format neural representations in these children to pre-tutoring levels observed in typically developing, especially in key brain regions associated with numerical cognition. Moreover, we identified distinct, ‘inverted U-shaped’ neurodevelopmental changes in the MD group, suggesting unique neural plasticity during mathematical skill development. Our findings highlight the effectiveness of targeted INS tutoring for remediating numerical deficits in MD, and offer a foundation for developing evidence-based educational interventions.Significance StatementFocusing on neural mechanisms, our study advances understanding of how numerical problem-solving can be enhanced in children with mathematical disabilities (MD). We evaluated an integrated number sense tutoring program designed to enhance connections between concrete (e.g. 2 dots) and symbolic (e.g. “2”) numerical representations. Remarkably, the tutoring program not only improved these children’s ability to process numbers similarly across formats but also enhanced their arithmetic skills, indicating transfer of learning to related domains. Importantly, tutoring normalized brain processing patterns in children with MD to resemble those of typically developing peers. These insights highlight the neural bases of successful interventions for MD, offering a foundation for developing targeted educational strategies that could markedly improve learning outcomes for children facing these challenges.

AbstractThe severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), causing human coronavirus disease 2019 (COVID-19), not only affects the respiratory tract, but also impacts other organs including the brain. A considerable number of COVID-19 patients develop neuropsychiatric symptoms that may linger for weeks and months and contribute to “long-COVID”. While the neurological symptoms of COVID-19 are well described, the cellular mechanisms of neurologic disorders attributed to the infection are still enigmatic. Here, we studied the effect of an infection with SARS-CoV-2 on the structure and expression of marker proteins of astrocytes and microglial cells in the frontal cortex of patients who died from COVID-19 in comparison to non-COVID-19 controls. Most of COVID-19 patients had microglial cells with retracted processes and rounded and enlarged cell bodies in both gray and white matter, as visualized by anti-Iba1 staining and confocal fluorescence microscopy. In addition, gray matter astrocytes in COVID-19 patients were frequently labeled by intense anti-GFAP staining, whereas in non-COVID-19 controls, most gray matter astrocytes expressed little GFAP. The most striking difference between astrocytes in COVID-19 patients and controls was found by anti-aquaporin-4 (AQP4) staining. In COVID-19 patients, a large number of gray matter astrocytes showed an increase in AQP4. In addition, AQP4 polarity was lost and AQP4 covered the entire cell, including the cell body and all cell processes, while in controls, AQP4 immunostaining was mainly detected in endfeet around blood vessels and did not visualize the cell body. In summary, our data suggest neuroinflammation upon SARS-CoV-2 infection including microgliosis and astrogliosis, including loss of AQP4 polarity.
