Published: January 2025

Background: Excessive use of smartphones and the Internet can lead to addiction and may increase the risk of developing mental disorders, particularly in the context of the COVID-19 outbreak. Objective: This systematic review and meta-analysis synthesized the existing literature reporting the impact of smartphone and Internet addiction on mental health during the COVID-19 pandemic. Methods: A systematic search was performed on two databases, PubMed and EMBASE, following the PRISMA guidelines to identify articles conducted from December 2019 when the COVID-19 pandemic began to emerge. Studies were selected based on pre-defined criteria and assessed for quality before inclusion in the meta-analysis. The main effect estimate gathered from eligible studies was the odds ratio, which was computed using the random-effects model. Results: Our findings demonstrated significant associations between Internet addiction and depression (OR = 4.09, 95% CI [3.28, 5.09]), Internet addiction and anxiety (OR = 3.08, 95% CI [2.08, 4.57]), smartphone addiction and depression (OR = 3.82, 95% CI [3.31, 4.40]), and smartphone addiction and anxiety (OR = 4.81, 95% CI [3.81, 6.07]) during the COVID-19 pandemic. Conclusion: This meta-analysis underscores that Internet and smartphone addiction increases the likelihood of developing mental disorders in the context of the COVID-19 pandemic. During the outbreak of infectious diseases, it is imperative for nations to not only address economic and educational challenges but also prioritize the mental well-being of their citizens.
Firm Value Impact of Global Oil and Gas Mergers and Acquisitions: The Role of Environmental Policy Framework
Authors: Yildirim Canan , Vanwalleghem Dieter 
Published: January 2025

The oil and gas (O&G) industry is under increasing pressure to decarbonize and adopt sustainable practices. While some firms are transitioning toward renewable energy, many continue to expand their traditional O&G operations. This study examines how financial markets perceive the value creation potential of business-as-usual mergers and acquisitions (M&As) by the world’s largest O&G companies from 2000 to 2021. Using an event study methodology, we focus on the role of home-country environmental policy stringency (EPS) in shaping market reactions. Our findings reveal that higher EPS in the acquirer’s home country is associated with a greater perceived loss in shareholder value upon the announcement of traditional O&G M&A deals, suggesting that EPS signals significant operational and financial risks related to hydrocarbon investments. However, when these deals are cross-border, the adverse impact of the acquirer’s home-market EPS diminishes, indicating that expanding beyond domestic markets may help O&G firms mitigate the financial consequences of stricter environmental regulations.

Background: Critical analysis of studies with high level of evidence has relied on the significance set by the reported P values. However, this strategy steers readers toward categorical interpretation of the data; therefore, a more comprehensive approach of data analysis is warranted. The continuous fragility index (CFI) allows for frailty interpretation of any given study's continuous outcome results. Purpose: To calculate the CFI of high-level quality studies reporting significant continuous outcomes on comparison of treatment modalities for management of femoroacetabular impingement syndrome. Study Design: Meta-analysis; Level of evidence, 2. Methods: Three databases (PubMed, Embase, Cochrane) were queried from inception to February 2024 utilizing Boolean operators to combine variations of the following search terms: “femoroacetabular impingement, randomized controlled trials or prospective cohort.” Studies were included if level of evidence 1 or 2, and a statistically significant outcome was reported for any continuous outcome. CFI calculation was performed for all significant outcomes to obtain a study-specific mean CFI and also for the primary outcome of each study. Mean CFI was also calculated for outcomes reported to be significant in >3 studies. Additionally, multivariable linear regression was utilized for assessment of variables associated with achievement of a higher CFI. Results: Thirteen studies totaling 1316 patients were included for analysis: 11 level of evidence 1 and 2 level of evidence 2 studies. A total of 48 outcomes reaching significance were extracted, with 8 representing primary outcomes. Study-specific mean (SD) CFI was 8 (9.3), whereas primary outcome mean CFI was 12.5 (12). In 4 of the 13 studies, the number of hips lost to follow-up was greater than the study CFI. Outcome-specific mean CFI was obtained for 5 outcomes reported in >3 studies. Multivariable linear regression revealed that larger sample size and greater journal impact factor had a significant positive association with a higher overall CFI value ( P < .05). Conclusion: The mean (SD) number of patient outcome events needed to reverse the significance of a continuous outcome (ie, CFI) was 8.0 (9.3). Nearly one-third of studies had a CFI less than the reported loss to follow-up, reflecting the need for better patient compliance to attain less fragile statistical results. Larger sample size and greater journal impact factor were both predictive of a higher CFI.

Published: January 2025

Background: Anterolateral ligament reconstruction (ALLR) or lateral extra-articular tenodesis (LET) has been used more frequently in conjunction with anterior cruciate ligament reconstruction (ACLR) in recent years. However, there are still concerns that these procedures may lead to complications such as overconstraint of the lateral compartment, stiffness, infections, tunnel convergence, and other intra- and postoperative complications because of increased surgical time and the need for additional procedures. Hypothesis/Purpose: The lateral extra-articular procedure will reduce the failure rate of reconstructed ACLs without increasing the number of complications. The purpose was to compare the complication and graft reinjury rates of 2 main anterolateral complex procedure categories described in the literature—LET and ALLR with isolated ACLR. Study Design: Systematic review and meta-analysis of randomized controlled trials (RTCs); Level of evidence, 2. Methods: The methodology followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The PubMed, Embase, and Cochrane Library databases were searched on March 15, 2024, to identify RTCs comparing isolated ACLR with ACLR + LET or ALLR. The methodological index for nonrandomized studies was employed for the quality evaluation. Complications and graft reinjury rates were recorded and meta-analyzed from all included studies. Results: The initial search yielded 1411 articles. Seventeen studies that included the complication rates (5 in the ALLR group and 12 in the LET group) were included in the review. No significant differences were found in the incidence of complications between the ACLR and ACLR + ALLR groups (Mantel-Haenszel [M-H], 1.20 [95% CI, 0.05-29.30]; P = .91) or between the ACLR and ACLR + LET groups (M-H, 0.39 [95% CI, 0.05-2.98]; P = .36). Significant differences were observed in the failure rate between the ACLR + ALLR group (M-H, 6.78 [95% CI, 1.98-23.22]; P = .002) and the ACLR + LET group (M-H, 3.14 [95% CI, 1.96- 5.04]; P < .00001). Conclusion: Adding a lateral extra-articular procedure, regardless of the surgical technique, can reduce the failure rate without increasing the number of complications at the mid-term follow-up. Study Registration: PROSPERO (CRD42023458354).

Authors: Park Jae Hee , Zhao Alan , Bain Rachel , Hassani Bessma , Tang Christina 
Published: January 2025

Background: Ceftriaxone is a third-generation cephalosporin commonly used for treating bacteremia caused by gram-positive organisms such as Streptococcus spp. and gram-negative organisms such as Enterobacterales. The typical doses for treating bacteremia are either 1 gram or 2 grams daily. Despite its widespread use, there are limited data on the optimal treatment dose for bacteremia. Methods: This IRB-approved retrospective cohort study evaluated the difference in the clinical failure rate among patients who received 1 gram or 2 grams of ceftriaxone once daily for documented bacteremia. Clinical failure was defined as a composite of the following: antibiotic escalation, escalation to intensive care, and 30-day readmission due to an infectious cause. Adult patients admitted to Long Island Jewish (LIJ) Valley Stream, LIJ Forest Hills, or LIJ Medical Center in 2022 who received ceftriaxone were reviewed for inclusion. Patients were excluded if they received ceftriaxone for endocarditis or meningitis, had a positive blood culture with a ceftriaxone-resistant pathogen, or received ceftriaxone for less than 72 hours. Results: A total of 128 patients were included in this study. Approximately 46.9% of the participants received a 1 gram dose, while 53.2% received a 2 gram dose. 35.4% of patients in the 2 gram group experienced clinical failure compared to 21.7% in the 1 gram group ( P = .08, OR 0.51; 95% CI 0.23-1.11). Conclusion: Our findings indicate that the primary outcome of clinical failure did not significantly differ between the 1 gram and 2 gram doses.

Published: January 2025

Novel polyarylates containing phthalazinone moieties (PAR-PH) were synthesized and characterized by co-solvent interfacial polymerization based on 4-(4′-hydroxyphenyl)-2,3-phthalazin-1-one (DHPZ) and isophthaloyl chloride (IPC). Effects of inorganic bases, monomer concentration, phase transfer catalysts and co-solvents on the interfacial polymerization reaction were investigated. When the organic phase solvent was cyclohexane with 3% butanone and 18-crown-6 was the phase transfer catalyst, PAR-PH achieved a maximum intrinsic viscosity ( η int) up to 0.52 dL/g. For some organic phase solvents of alkanes and chlorinated hydrocarbons, the addition of co-solvents increased the η int of the polymer. PAR-PH exhibit excellent thermal resistance due to the introduction of rigid twisted phthalazinone moieties into the polymer main chains, with glass transition temperature ( T g) of 275°C. The 5% thermal weight loss temperature of PAR-PH was 463°C in N2 and residual mass ratios at 800°C of 52.0%, demonstrating excellent thermal stability.

Published: January 2025

Introduction: Maternal, placental and foetal factors together or in isolation influence the well-being of the foetus. The two most important causes of intrauterine growth retardation (IUGR) and intrauterine death (IUD) are placental factors and hypoxemia. Material & Methods: The present study was a prospective study conducted in the Department of Pathology. Placentas of IUD and IUGR cases were collected and routinely processed. Results: There were a total of 52 placentas, 40 from IUD cases and 12 from IUGR cases. Gross infarction was identified in 13.46% cases and microscopic infarction in 23.1% cases which were the most common findings. Conclusion: Chorioamnionitis was the most common histological finding in both IUGR and IUD cases. Careful examination of the placenta is necessary in IUD and IUGR cases.

A systematic review of reasons for and against euthanasia and physician-assisted suicide in older people with a non-terminal condition
Authors: Baée James , Draper Brian , Wijeratne Chanaka 
Published: January 2025

Objective Some European jurisdictions have legalised euthanasia and physician-assisted suicide (EUT/PAS) for people with dementia and ‘multiple geriatric syndromes’. We therefore sought to determine the published rationales for and against providing EUT/PAS to older people without a terminal illness. Method A systematic review was undertaken according to PRISMA guidelines. Content, thematic and discourse analyses were used to identify papers that delineated ethical arguments for and against the provision of EUT/PAS to older people without a terminal illness, and to synthesise arguments into overarching themes. Results Seventeen studies were included, eight of which were written by medical practitioners, the rest by ethicists. All but two of the papers were written by authors from western nations. A total of 70 arguments were identified, 16 (22.9%) being in favour of EUT/PAS, and 54 (77.1%) against. The themes identified were: a person with dementia had a duty to die, precedent capacity, ageism, abuse/coercion, psychological factors, healthcare economics, sociocultural factors and legislation. Conclusion Despite broad scepticism about the provision of EUT/PAS to older people without a terminal illness, the literature is preliminary. There is a need for ethicists and policymakers to engage with a range of older people with physical, cognitive and social needs, as well as their supporters.

Background: Circulating rare cells participate in breast cancer evolution as systemic components of the disease and thus, are a source of theranostic information. Exploration of cancer-associated rare cells is in its infancy. Objectives: We aimed to investigate and classify abnormalities in the circulating rare cell population among early-stage breast cancer patients using fluorescence marker identification and cytomorphology. In addition, we sought to determine the dependency of these markers on the presence of tumors. Design: We evaluated the validity of a multi-rare-cell detection platform and demonstrated the utility of a specific rare cell subset as a novel approach to characterize the breast cancer system. Sampling was conducted both before and after tumor resection. Methods: Linearity of the Rarmax platform was established using a spike-in approach. The platform includes red blood cell lysis, leukocyte depletion and high-resolution fluorescence image recording. Rare cell analysis was conducted on 28 samples (before and after surgery) from 14 patients with breast cancer, 20 healthy volunteers and 9 noncancer control volunteers. In-depth identification of rare cells, including circulating tumor cells, endothelial-like cells, erythroblasts, and inflammation-associated cells, was performed using a phenotype and morphology-based classification system. Results: The platform performed linearly over a range of 5 to 950 spiked cells, with an average recovery of 84.6%. Circulating epithelial and endothelial-like cell subsets have been demonstrated to be associated with or independent of cancer with tumor presence. Furthermore, certain cell profile patterns may be associated with treatment-related adverse effects. The sensitivity in detecting tumor-presence and cancer-associated abnormality before surgery was 43% and 85.7%, respectively, and the specificity was 100% and 96.6%, respectively. Conclusion: This study supports the idea of a cancer-associated rare cell abnormality to represent tumor entities as well as systemic cancer. The latter is independent of the apparent clinical cancer.

Published: January 2025

The lateral plates are usually used in the field of structural design of acoustic metamaterials (AMs), which can realize the control of AMs on sound waves. Presently, researches on the application of AMs with lateral plates mainly focus on the regulation of sound waves in air media, and rarely involve the research on their underwater acoustic properties. Therefore, a composite acoustic structure is designed by inserting regularly distributed lateral plates into the viscoelastic rubber, and then, the AMs with multiple coupling substructure (AMs-MCS) can be obtained through combining the local resonance structure and functional gradient structure. Based on underwater acoustic calculation model for the functional gradient acoustic structure established by grade finite element method (G-FEM), the underwater sound absorption characteristics of the AMs-MCS are studied, and the influence of each substructure on the acoustic performance of the AMs-MCS is explored. Numerical results indicate inserting gradient-distributed multiple lateral plates inside the homogeneous acoustic structure can improve the sound absorption performance of the acoustic structure in the mid-and high-frequency ranges and the sound absorption frequency band of the acoustic structure can be effectively broadened. Moreover, the sound absorption coefficient of the AMs-MCS is greater than 0.8 at 500Hz-10 kHz, and the average sound absorption coefficient reaches 0.893, thus achieving low-frequency and broadband sound absorption performance.

Published: January 2025

With its unique three-dimensional structure, high porosity, and lightweight, warp-knitted spacer fabric (WKSF) is an excellent insulation material. Multilayer fabric is an effective solution for better heat control, meeting the different requirements of a wide range of applications in the field of temperature control. To know the relationship between structural parameters and heat conductivity, this study highlighted the heat transfer mechanism of multilayer WKSFs. Experimental WKSF samples were fabricated in a double needle bar warp knitting machine and had mesh and plain side layers, different thicknesses of 3 mm, 4 mm, and 4.7 mm. These samples were grouped into multilayer systems by changing thickness and contacting modes between two samples. Experimental results show that the number of layers and the type of contact between the layers affects the internal thermal convection of the multilayer system and thus has a significant effect on its thermal resistance. Also, the WKSF thickness plays a role in the thermal resistance of the multilayer system. To further clarify the heat conducting behavior from a microscopic perspective, a geometry model of multilayer WKSFs and transfer of heat physical field was constructed to perform finite element simulation by ANSYS. By comparing the simulation results with the test results, the established simulation model was practical and it was found that the heat transfer paths of multilayer WKSFs were affected by the distribution of media with different thermal conductivities. The research provides a theoretical reference for studies on thermal insulation materials.

Background: After breast cancer (BC), women may face other severe symptoms such as sleep problems. The use of simple, fast, and reliable scales is necessary in the clinic to improve patient benefits, and sleep is an important aspect to be addressed. Objective: This study was conducted to adapt and validate the Spanish version of the satisfaction, alertness, timing, efficiency, and duration (SATED) scale for measuring sleep health in women who have completed treatment for BC in Spain (SATED-BC). Design: Cross-sectional study. Methods: The adaptation process involved adding a sixth item to the SATED-BC scale: “the impact of symptoms experienced after completing breast cancer treatment on sleep” item was not considered for scoring. The SATED-BC score ranged from 0 (poorest sleep health) to 10 (best sleep health). A validation analysis was performed using the Pittsburgh Sleep Quality Index, the Consensus Sleep Diary, and actigraphy, and the results were compared with those obtained using the SATED-BC scale. Results: The SATED-BC scale was reliable in terms of its internal consistency (Cronbach’s α = 0.70; McDonald’s ω = 0.72), showed high intrasubject reliability ( r = 0.90), and was shown to be valid for use in women who have completed treatment for breast cancer. Conclusion: The SATED-BC scale is a reliable and valid tool for comprehensively evaluating sleep health in women who have completed treatment for breast cancer.
