Published: January 2024

Abstract
Time-frequency analysis could provide detailed dynamic information of celestial bodies and is critical for comprehension of astronomical phenomena. However, it is far from being well-developed in astronomy. Hilbert–Huang transform (HHT) is an advanced time-frequency method but has two problems in analysing astronomical signals. One is that many astronomical signals may be composed of multiple components with various amplitudes and frequencies, while HHT uses assisted noises with the same amplitude to extract all components. The other is that HHT is an empirical method requiring tunable parameters to be optimized using experimental results or known facts, which are challenging to obtain in astronomy and it is therefore hard to determine whether the signal decomposition is right or not. In this study, we adjust the noise amplitude to optimize the decomposition based on the orthogonality of the obtained components and discard the decompositions with non-physical results. Three experiments show that this new extension of HHT is an effective method suitable for high-resolution time-frequency analysis in astronomy. It can be used to dig out valuable pieces of information which are inaccessible with other methods, and thus has the potential to open up new avenues for astronomy research.

Abstract
We propose a simple and computationally attractive method to deal with missing data in in cross-sectional asset pricing using conditional mean imputations and weighted least squares, cast in a generalized method of moments (GMM) framework. This method allows us to use all observations with observed returns; it results in valid inference; and it can be applied in nonlinear and high-dimensional settings. In simulations, we find it performs almost as well as the efficient but computationally costly GMM estimator. We apply our procedure to a large panel of return predictors and find that it leads to improved out-of-sample predictability.

Treatment Fidelity in 94 Randomized Controlled Trials of Physical Rehabilitation in the ICU: A Scoping Review*
Authors: Farley Christopher , Newman Anastasia N.L. , Hoogenes Jen , Brooks Dina , Duffett Mark , Kho Michelle E. 
Published: January 2024

OBJECTIVES:
Recent reviews demonstrated discordant effects of ICU-based physical rehabilitation on physical function. These inconsistencies may be related to differences in treatment fidelity—the extent to which a protocol is delivered as planned. Before evaluating the association of fidelity with outcomes, we must first understand the extent of treatment fidelity reporting in ICU-based physical rehabilitation randomized controlled trials (RCTs).

DATA SOURCES:
Six electronic databases from inception to December 2022.

STUDY SELECTION:
We included RCTs enrolling adults or children admitted to the ICU, if greater than or equal to 50% were invasively mechanically ventilated greater than 24 hours, and underwent an ICU-based physical rehabilitation intervention, with no limitation to comparators or outcomes.

DATA EXTRACTION:
We screened and extracted data independently and in duplicate, with a third reviewer as needed. Extracted data included study characteristics, treatment descriptions, and the presence of National Institutes of Health Behaviour Change Consortium (NIH-BCC) treatment fidelity tool components. Treatment fidelity scores were calculated as the proportion of reported (numerator) out of total NIH-BCC components (denominator). We calculated scores across studies and by treatment group (intervention vs. comparator). We used linear regression to assess for a time trend in study treatment fidelity scores.

DATA SYNTHESIS:
Of 20,433 citations, 94 studies met inclusion criteria. Authors reported a median (first–third quartiles) of 19% (14–26%) of treatment fidelity components across studies. Intervention group scores were higher than comparator groups (24% [19–33%] vs. 14% [5–24%], p < 0.01). We found a mean increase in study treatment fidelity scores by 0.7% (0.3 points) per year.

CONCLUSIONS:
Only 19% of treatment fidelity components were reported across studies, with comparator groups more poorly reported. Future research could investigate ways to optimize treatment fidelity reporting and determine characteristics associated with treatment fidelity conduct in ICU-based physical rehabilitation RCTs.
Bilateral Forehead Rotation Flap with Skin Substitute Application for Convexity Replacement
Authors: Lauck Kyle C. , Rickstrew Jace J. , Tolkachjov Stanislav N. 
Published: January 2024

Summary:
Large forehead defects pose reconstructive challenges, considering the tissue inelasticity and the need to preserve symmetry of the eyebrow and hairline. Local skin flaps and primary closures are mainstays of forehead reconstruction with many techniques reported, but they may not cover the entire defect. Further closure options with acceptable cosmesis are limited. While providing a functional alternative, skin grafting may take on an atrophic concavity and shiny texture. Free flaps similarly may not accurately replicate the contour of the forehead and may be discordant with the texture of adjacent skin. We describe a reproducible technique for closing a large central forehead defect in a single-stage local flap while retaining symmetry of eyebrows and neurovascular integrity. We also propose serially applying a skin substitute to the remaining portion of the defect to recreate forehead convexity and potentially expedite healing. This technique may represent a viable and reproducible method for recreating the natural contour of the forehead when complete closure may not be an option.
Persistent Monkeypox-Associated Keratouveitis in a Post-LASIK Cornea: A Case Report With Flap Removal
Authors: Rosell Domínguez María , Hernández-Cerdá Jorge , Alegre-Ituarte Víctor , González-Ocampo Dorta Samuel , Martínez-Costa Pérez Lucía 
Published: January 2024

Purpose:
This study aimed to report a case of persistent keratouveitis associated with mpox virus infection in an immunocompetent patient with a history of laser-assisted in situ keratomileusis (LASIK), leading to the need for flap removal.

Methods:
A comprehensive literature review was conducted, and a detailed case report was presented.

Results:
A 44-year-old immunocompetent male patient with a history of LASIK and HIV infection presented with conjunctival and corneal lesions indicative of mpox infection. Despite initial topical treatment, the condition worsened, leading to severe epithelial and stromal keratitis with anterior chamber inflammation. Polymerase chain reaction testing confirmed the presence of mpox virus in conjunctival, corneal, and aqueous humor samples. The patient underwent various treatments, including tecovirimat, oral and topical corticosteroids, and topical trifluridine, and eventually flap removal with amniotic membrane application. Subsequent polymerase chain reaction testing of the aqueous humor yielded negative results, and the cornea gradually reepithelialized without inflammation. After 8 months, the patient's eye remained stable, with a central stromal scar.

Conclusions:
This case highlights the rare occurrence of mpox-associated keratouveitis and emphasizes the challenges faced in its management. The successful outcome achieved through a combination of antiviral therapy, antiinflammatories, and surgical intervention underscores the importance of a multidisciplinary approach in managing such cases.

Authors: Tong Chaoyang , Du Xinwei , Chen Yancheng , Zhang Kan , Shan Mengqin , Shen Ziyun , Zhang Haibo , Zheng Jijian 
Published: January 2024

Background:
Major adverse postoperative outcomes (APOs) can greatly affect mortality, hospital stay, care management and planning, and quality of life. This study aimed to evaluate the performance of five machine learning (ML) algorithms for predicting four major APOs after pediatric congenital heart surgery and their clinically meaningful model interpretations.

Methods:
Between August 2014 and December 2021, 23 000 consecutive pediatric patients receiving congenital heart surgery were enrolled. Based on the split date of 1 January 2019, the authors selected 13 927 participants for the training cohort, and 9073 participants for the testing cohort. Four predefined major APOs including low cardiac output syndrome (LCOS), pneumonia, renal failure, and deep venous thrombosis (DVT) were investigated. Thirty-nine clinical and laboratory features were inputted in five ML models: light gradient boosting machine (LightGBM), logistic regression (LR), support vector machine, random forest, and CatBoost. The performance and interpretations of ML models were evaluated using the area under the receiver operating characteristic curve (AUC) and Shapley Additive Explanations (SHAP).

Results:
In the training cohort, CatBoost algorithms outperformed others with the mean AUCs of 0.908 for LCOS and 0.957 for renal failure, while LightGBM and LR achieved the best mean AUCs of 0.886 for pneumonia and 0.942 for DVT, respectively. In the testing cohort, the best-performing ML model for each major APOs with the following mean AUCs: LCOS (LightGBM), 0.893 (95% CI: 0.884–0.895); pneumonia (LR), 0.929 (95% CI: 0.926–0.931); renal failure (LightGBM), 0.963 (95% CI: 0.947–0.979), and DVT (LightGBM), 0.970 (95% CI: 0.953–0.982). The performance of ML models using only clinical variables was slightly lower than those using combined data, with the mean AUCs of 0.873 for LCOS, 0.894 for pneumonia, 0.953 for renal failure, and 0.933 for DVT. The SHAP showed that mechanical ventilation time was the most important contributor of four major APOs.

Conclusions:
In pediatric congenital heart surgery, the established ML model can accurately predict the risk of four major APOs, providing reliable interpretations for high-risk contributor identification and informed clinical decisions-making.
Secondary analysis: heat and self-report pain sensitivity associate with biological sex and racialized sociocultural group but may not be mediated by anxiety or pain catastrophizing

Published: January 2024

Abstract

Introduction:
Previous studies have demonstrated associations between sex and racialized group on pain sensitivity and tolerance. We analyzed the association of sex and racialized group on heat pain sensitivity, sensibility to painful suprathreshold mechanical pain (STMP), and pain sensitivity questionnaire (PSQ). We hypothesized that anxiety and pain catastrophizing reported by racialized minority groups and women would mediate enhanced pain sensitivity. Our secondary aim was to evaluate validity of the PSQ in a diverse population.

Methods:
Using quantitative sensory testing for painful heat, STMP (forces: 64, 128, 256, and 512 mN), and PSQ, we evaluated pain sensitivity in 134 healthy participants [34 (18 women) Asian, 25 (13 women) Black, and 75 (41 women) White]. We used general linear and linear mixed models to analyze outcomes. We assessed mediation of state and trait anxiety and pain catastrophizing on pain sensitivity.

Results:
Racialized minority status was associated with greater heat pain sensitivity (F = 7.63; P = 0.00074) and PSQ scores (F = 15.45; P = 9.84 × 10−7) but not associated with STMP (F = 1.50; P = 0.23). Female sex was associated with greater heat pain sensitivity (F = 4.9; P = 0.029) and lower PSQ (F = 9.50; P = 0.0025) but not associated with STMP (F = 0.0018; P = 0.97). Neither anxiety nor pain catastrophizing mediated associations between sex or racialized group with heat pain threshold or PSQ. Differential experience of individual items (F = 19.87; P = 3.28 × 10−8) limited PSQ face validity in racialized minorities.

Conclusion:
Consistent with previous research, sensitivity to painful heat was associated with racialized minority status and female sex. By contrast, there was no significant effect of racialized minority status or female sex on STMP. Some PSQ items are inapplicable to participants from racialized minority groups.

Objective:Social determinants of health (SDH) are important determinants of long-term conditions and multimorbidity in the general population. The intersecting relationship between SDH and multimorbidity in people with HIV remains poorly studied.Design:A cross-sectional study investigating the relationships between eight socio-economic parameters and prevalent comorbidities of clinical significance and multimorbidity in adults of African ancestry with HIV aged 18–65 years in South London, UK.Methods:Multivariable logistic regression analysis was used to evaluate associations between SDH and comorbidities and multimorbidity.Results:Between September 2020 and January 2022, 398 participants (median age 52 years, 55% women) were enrolled; 85% reported at least one SDH and 72% had at least one comorbidity. There were no associations between SDH and diabetes mellitus or kidney disease, few associations between SDH (job and food insecurity) and cardiovascular or lung disease, and multiple associations between SDH (financial, food, housing and job insecurity, low educational level, social isolation, and discrimination) and poor mental health or chronic pain. Associations between SDH and multimorbidity mirrored those for constituent comorbidities.Conclusion:We demonstrate strong associations between SDH and poor mental health, chronic pain and multimorbidity in people of black ethnicities living with HIV in the UK. These findings highlight the likely impact of enduring socioeconomic hardship in these communities and underlines the importance of holistic health and social care for people with HIV to address these adverse psychosocial conditions.

Published: January 2024

Objective:
To compare the short- and long-term outcomes between robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) for gastric cancer.

Summary Background Data:
The clinical outcomes of RG over LG have not yet been effectively demonstrated.

Methods:
This retrospective cohort study included 3,599 patients with gastric cancer who underwent radical gastrectomy at eight high-volume hospitals in China from August 2016 to June 2019. Propensity score matching (PSM) was performed between patients who received RG and LG. The primary endpoint was 3-year disease-free survival (DFS).

Results:
After 1:1 PSM, 1034 pairs of patients were enrolled in a balanced cohort for further analysis. The 3-year DFS in the RG and LG was 83.7% and 83.1% (P=0.745), respectively, and the 3-year overall survival (OS) was 85.2% and 84.4%, respectively (P=0.647). During three years of follow-up, 154 patients in the RG and LG groups relapsed (cumulative incidence of recurrence: 15.0% vs. 15.0%, P=0.988). There was no significant difference in the recurrence sites between the two groups (all P>0.05). Sensitivity analysis showed that RG had comparable 3-year DFS (77.4% vs. 76.7%, P=0.745) and OS (79.7% vs. 78.4%, P=0.577) to LG in patients with advanced (pathological T2-4a) disease, and the recurrence pattern within three years was also similar between the two groups (all P>0.05). RG had less intraoperative blood loss, lower conversion rate, and shorter hospital stays than LG (all P>0.05).

Conclusions:
For resectable gastric cancer, including advanced cases, RG is a safe approach with comparable 3-year oncological outcomes to LG when performed by experienced surgeons.
Perceived Barriers to Using Neurostimulation
Authors: Cortright Marissa K. , Bluhm Robyn , Achtyes Eric D. , McCright Aaron M. , Cabrera Laura Y. 
Published: January 2024

Objectives
Neurostimulation interventions often face heightened barriers limiting patient access. The objective of this study is to examine different stakeholders' perceived barriers to using different neurostimulation interventions for depression.

Methods
We administered national surveys with an embedded experiment to 4 nationwide samples of psychiatrists (n = 505), people diagnosed with depression (n = 1050), caregivers of people with depression (n = 1026), and members of the general public (n = 1022). We randomly assigned respondents to 1 of 8 conditions using a full factorial experimental design: 4 neurostimulation modalities (electroconvulsive therapy [ECT], repetitive transcranial magnetic stimulation [rTMS], deep brain stimulation [DBS], or adaptive brain implants [ABIs]) by 2 depression severity levels (moderate or severe). We asked participants to rank from a list what they perceived as the top 3 barriers to using their assigned intervention. We analyzed the data with analysis of variance and logistic regression.

Results
Nonclinicians most frequently reported “limited evidence of the treatment's effectiveness” and “lack of understanding of intervention” as their top 2 most important practical barriers to using ECT and TMS, respectively. Compared with nonclinicians, psychiatrists were more likely to identify “stigma about treatment” for ECT and “lack of insurance coverage” for TMS as the most important barriers.

Conclusions
Overall, psychiatrists' perceptions of the most important barriers to using neurostimulation interventions were significantly different than those of nonclinicians. Perceived barriers were significantly different for implantable DBS and ABI) versus nonimplantable (rTMS and ECT) neurostimulation interventions. Better understanding of how these barriers vary by neurostimulation and stakeholder group could help us address structural and attitudinal barriers to effective use of these interventions.

Authors: Smith Joshua R. , Baldwin Isaac , Termini Katherine Audrey , McGonigle Trey , Vandekar Simon , Luccarelli James 
Published: January 2024

Objectives
The objective study was to investigate the safety and efficacy of electroconvulsive therapy (ECT) in a retrospective cohort of pediatric patients.

Methods
A single-site retrospective analysis was conducted of patients aged younger than 18 years who received ECT in a private university hospital from January 28, 2012 to April 8, 2023. Treatment efficacy and adverse events were determined retrospectively through review of the medical record.

Results
A total of 36 pediatric patients met the inclusion criteria. Catatonia was the most common presenting indication for ECT, followed by psychosis and suicidal ideation. For all patients, Clinical Global Impressions–Improvement scale scores indicated that it was very likely for a subject to experience at least “much improvement” with the estimated probability of receiving a Clinical Global Impressions–Improvement scale score better than 3 of 0.852 (t.s. = 16.3; P < 0.001; 95% confidence interval, 0.711–0.931). All patients with catatonia demonstrated a positive clinical response and experienced a statistically significant reduction in total Bush-Francis Catatonia Rating Scale scores observed (t = 11.9; df = 20; SD = 6.3; P < 0.001; 95% confidence interval, 12.6–17.9). No significant adverse events were reported for any patient in the cohort. However, 14 (38.9%) patients experienced prolonged seizures, all of which were terminated with propofol (mean, 49.7 mg).

Conclusions
This study provides further data supporting the safe and effective use of pediatric ECT in the treatment of various psychiatric conditions. However, more research is needed to determine the risk factors associated with prolonged seizures and the optimal seizure parameters in young people.
Scattering kernel of an array of floating ice floes: application to water wave transport in the marginal ice zone
Authors: Montiel F. , Meylan M. H. , Hawkins S. C. 
Published: January 2024

A radiative transfer model of water wave scattering in the marginal ice zone is considered. In this context, wave energy redistribution across the directional components of the spectrum as a result of scattering by the constituent ice floes is typically modelled via a scattering kernel describing the far-field directionality of the scattered wave field produced by a single floe in isolation. Recognizing the potential importance of the floe size distribution (FSD) on wave scattering, we propose an enhanced scattering kernel constructed from the far-field scattering pattern of a circular array of floes. This is achieved by solving the self-consistent multiple scattering of a time-harmonic plane wave by a large array of floating circular floes with radii sampled from a prescribed FSD. A fast multipole method is implemented to accelerate the numerical estimation of the solution. Simulations are then conducted to characterize the properties of the scattering kernel for a range of configurations. It is found that the scattering kernel obtained for a wide array has a large, narrow transmission peak in the forward direction, while it uniformizes low-amplitude scattered waves in other directions. An idealized application to radiative transfer theory is also considered.
