Abstract

Purpose
The purpose of this study was to evaluate the long-term prognosis of iatrogenic saphenous nerve (SN) injuries incurred during hamstring tendon harvesting for anterior cruciate ligament (ACL) reconstruction and their impact on clinical outcomes and patient satisfaction at least two years postoperatively.
Materials and Methods
A retrospective review was conducted on patients who underwent ACL reconstruction with hamstring tendon grafts at a single institution between January 2015 and January 2020. The study assessed the incidence of SN injuries immediately after surgery and at final follow-up, the recovery rate and time, and the impact of these injuries on functional outcomes using the Lysholm Knee Score (LKS) and patient-reported effects on daily activities.
Results
Out of 159 patients analyzed, iatrogenic SN injury was initially observed in 87 (54.7%) patients post-ACLR. At the final follow-up, paresthesia had resolved in 36 (22.6%) patients within an average of 11.1 months. Persistent SN injury was noted in 51 (32.1%) patients, with varying involvement of the infrapatellar branch of the saphenous nerve (IPBSN) and the sartorial branch (SBSN). Patients with consistent SN injury reported a significant impact on daily activities and had lower LKS scores compared to those without injury or with recovered injury. A higher re-rupture rate was associated with persistent SN injury.
Conclusions
SN injuries during hamstring graft harvesting for ACL reconstruction are common, with a significant portion of patients experiencing persistent sensory deficits at least two years postoperatively. These injuries can adversely affect patient satisfaction and functional outcomes and increase the re-rupture rate.

Abstract

Background TG/HDL-C is a confirmed predictive factor for insulin resistance and is suggested to be closely related to nonalcoholic fatty liver disease (NAFLD), but previous research is inconclusive. The association between TG/HDL-C and NAFLD incidence was further explored in this large-sample, long-term retrospective cohort study.Methods Individuals who participated in the Kailuan Group health examination from July 2006 to December 2007 (n = 49,518) were included. Data from anthropometric and biochemical indices, epidemiological surveys, and liver ultrasound examinations were collected and analysed statistically, focusing on the association between TG/HDL-C and the incidence of NAFLD.Results During a mean follow-up period of 7.62 ± 3.99 years, 24838 participants developed NAFLD. The cumulative NAFLD incidences associated with the first to fourth quartiles of TG/HDL-C were 59.16%, 65.04%, 71.27%, and 79.28%, respectively. The multivariate Cox proportional hazards regression model showed that the hazard ratios (HRs) (95% CIs) for NAFLD in the second, third, and fourth quartiles were 1.20 (1.16–1.25), 1.50 (1.45–1.56), and 2.02 (1.95–2.10) (P for trend < 0.05), respectively, and the HR (95% CI) corresponding to an increase of one standard deviation in TG/HDL-C was 1.10 (1.09–1.11) (P < 0.05). Subsequent subgroup and sensitivity analyses yielded results similar to those of the main analyses.Conclusions TG/HDL-C is independently associated with NAFLD risk, with higher TG/HDL-C indicating a greater NAFLD risk.

Abstract

HSCT has been recognized as a successful treatment for various hematological disease. The 5-year survival rate for children and adolescents diagnosed with hematological disease has risen to over 90% in high-income countries. Nevertheless, it has been reported that between 65-84% of individuals who undergo HSCT suffer from premature ovarian failure(POF), with only 0.6% managing to conceive successfully. To report the 5-year experience and evaluate the fertility of young female survivors in HSCT at Peking University People's Hospital, a total of 102 pediatric and female patients aged 8-35 years who underwent HSCT were included. The incidence of POF was 88.2%, 93.9% and 61.5% for young female AML, ALL and AA patients, respectively. The AA group (p=0.028) had a significantly lower incidence of POF. In the POF group, 89% of patients underwent haploidentical related donor HSCT (p=0.364) and the CED of these patients was 10391 mg/m2 (4890, 10589) (p=0.222).According to the univariate analysis, patients who were ≥13 years old at the time of HSCT (p=0.007), who were diagnosed with AA (p=0.028), who experienced menarche before HSCT and amenorrhea after HSCT (p=0.016) had a higher incidence of POF. Multivariate analysis was performed that only age at HSCT was independently associated with POF post-HSCT.
Preexisting Mental Disorders and Mental Distress During the Pandemic
: The Roles of Stress, Risk Perception, and Loneliness
Authors: Kwon Soyoung 
Published: July 2024

Abstract

Purpose. The COVID-19 pandemic has imposed unprecedented stressors on individuals globally, leading to significant mental health challenges. This study examines the relationship between perceived adversities experienced during the pandemic—such as stress, risk perception, and loneliness—and the mental health outcomes of individuals with a specific focus on those already grappling with mental disorders.
Methods. The study analyzed data from 8,259 adults who participated in surveys between waves 4 (April 2020) and 29 (June 2021) of the Understanding American Study. Participants self-reported their psychiatric diagnosis history and completed self-report measures of mental distress (PHQ-4), perceived stress, risk perception, and loneliness.
Results. Those with preexisting comorbid mental disorders reported higher levels of mental distress, COVID-19 risk perception, perceived stress as well as more days experiencing loneliness during the pandemic. Perceived adversities—stress, risk perception, and loneliness—were all positively associated with increased mental distress, indicating the risk factors for mental distress during the pandemic. Among these factors, loneliness was identified as the primary contributor, accounting for 30%-40% of the mental health gap between individuals with and without preexisting mental diagnoses. Also, the detrimental impact of these adversities was more pronounced for those with preexisting mental disorders.
Conclusion. The research highlights that those with preexisting mental disorders, particularly those with comorbidities, face an increased risk of experiencing mental distress during the COVID-19 pandemic. These findings underscore the critical importance of providing targeted support and interventions specifically designed for this vulnerable population, with a particular focus on addressing loneliness.

Ongoing Range Shift of Mangrove Foundation Species: Avicennia germinans and Rhizophora mangle in Georgia, USA
Authors: Vervaeke William , Feller Ilka , Jones Scott 
Published: July 2024

Abstract

Ongoing climate change is leading to shifting vegetation patterns in coastal areas worldwide. One such shift in vegetation is the ability of tropical species to establish and survive farther north than they would have in the past. A well-studied example of this tropicalization is the expansion of mangroves at the marsh-mangrove ecotone, thought to be controlled by a decrease in extreme freeze events in the SE USA. However, accurate mangrove distribution data at their poleward limit in this region is currently lacking. Here, we report information collected from targeted surveys along the Atlantic coasts of Florida and Georgia at the poleward limit of mangroves in the USA. We document both Avicennia germinans and Rhizophora mangle individuals naturally occuring in Georgia, USA, poleward of previous reports by more than 23 km (A. germinans) and by almost 80 km (R. mangle), respectively. Results highlight the lack of distributional information in this under-sampled region, and the need for additional study of species-specific physiology and tolerance, especially for R. mangle which exhibited surprising resilience and responses to freeze events. These data will be crucial to validate models showing a northern shift of mangroves. Knowing where mangroves have established and the associated conditions that allowed establishment will help inform models of tropicalization and ecotonal shifts in areas where foundation species are expanding, giving managers and researchers needed insight as current landscapes change.

Published: July 2024

Abstract

Background
Kidney cancer, a prevalent malignant tumor in the urinary system, poses a significant disease burden and remains a crucial public health concern.
Methods
Utilizing GBD2021 data, our study examined the standardized incidence, mortality, prevalence, and DALYs rate of renal cancer. We calculated the (1-MIR) value to assess treatment outcomes and survival rates, employed a joinpoint regression model to determine the AAPC, and conducted comparative and longitudinal analyses between China and global trends. Through the joinpoint regression model, we calculated the AAPC and conducted a comprehensive analysis of the disease burden of kidney cancer, evaluating its current status and changing trends.
Results
From 1990 to 2021, the age-standardized incidence rate, age-standardized mortality rate, age-standardized prevalence rate, and age-standardized DALYs rate of kidney cancer in China were lower than those in the world as a whole. However, the growth rate in China was significantly faster than the global average. The age-standardized incidence rate and prevalence rate of kidney cancer in males showed a greater increase compared to females, both in China and globally. Additionally, the age-standardized rate of kidney cancer in males was notably higher than in females, particularly among middle-aged males. The (1-MIR) of renal cancer increased from 0.36 to 0.62 in China and from 0.49 to 0.58 globally. Overall, the treatment effect of renal cancer has shown some successful outcomes.
Conclusions
From 1990 to 2021, there was a noticeable increase in the global incidence of kidney cancer. Specifically, the standardized incidence and prevalence of kidney cancer in the Chinese population saw a more rapid rise compared to the global trend. Additionally, the disease burden of kidney cancer remained significantly higher in males than in females.
Voluntary Participation Mediates the Relationship between Diversified Online Community Engagement and Subjective Life Satisfaction among Chinese Populations: From a gender perspective
Authors: Huang Xiaorui , Fu Mingqi 
Published: July 2024

Abstract

Background: Whether and how might the diversity of engaged online communities relates to subjective life satisfaction remain unclear in Chinese population. This study with a gender perspective examines the role of increased voluntary participation in the relationship above.
Study Design: A cross-sectional study based on 2,558 respondents recruited from the Chinese Social Survey (CSS), wave 2019.
Results: A greater diversity of engagement in online communities associated with better subjective life satisfaction among both males (B=0.31, se=0.11) and females (B=0.10, se=0.02). More detailed, the positive relationship above was partially (6.6%) mediated by increased voluntary participation among females, as individuals involved in a wider variety of online communities were associated with increased likelihood of engaging in voluntary activities (B=0.006, Z=3.910), which in turn contributed to higher levels of subjective life satisfaction (B=0.114, Z=2.760). However, voluntary participation demonstrated nonsignificant mediating role in the relationship between diversified online community engagement and subjective life satisfaction.
Conclusion: Findings of this study provide valuable insights into the nuanced ways in which online interactions can affect voluntary participation and well-being, highlighting the importance of considering gender differences in these dynamics.

Abstract

Micro- and nanoplastics can interact with a variety of biologically active compounds forming aggregates of which the effects have yet to be understood. To this end, it is vital to characterize these aggregates of key compounds and micro- and nanoplastics. In this study, we examined the adsorption of the antibiotic tetracycline on four different nanoplastics, made of polyethylene (PE), polypropylene (PP), polystyrene (PS), and nylon 6,6 (N66) through chemical computation. Two separate approaches were employed to generate relevant conformations of the tetracycline-plastic complexes. In the first approach, we folded the plastic particle from individual polymer chains in the presence of the drug through multiple separate simulated annealing setups. In the second, more biased, approach, the neat plastic was pre-folded through simulated annealing, and the drug was placed at its surface in multiple orientations. The former approach was found to be clearly superior to the other, being able to obtain lower energy conformations even with the antibiotic buried inside the plastic particle. Quantum chemical calculations on the structures revealed that the adsorption energies show a trend of of decreasing affinity to the drug in the order of N66 > PS > PP > PE. In vitro experiments on tetracycline-sensitive cell lines demonstrated that, in qualitative agreement with the calculations, in the presence of PS particles the biological activity of tetracycline drops significantly. Preliminary molecular dynamics simulations on two selected aggregates with each plastic served as first stability test of the aggregates under influence of temperature and in water. We found that all of the selected cases persisted in water indicating that the aggregates may be stable also in more realistic environments.

Abstract

Electrocatalytic reduction of CO2 can convert CO2 into a variety of carbon-based fuels and achieve carbon neutrality. Tin oxide (SnO2) electrocatalytic materials have the advantages of low cost and low toxicity, and the electrocatalytic reduction of CO2 to formic acid is highly selective. In this paper, Pd-doped SnO2 nanoparticle materials were synthesized by flame spray pyrolysis and their properties for electrocatalytic reduction of CO2 to formic acid were explored in a gas diffusion electrolytic cell. The results showed that the Pd/SnO2 catalysts could improve the catalytic activity for the conversion of CO2 to formate, and the most superior 0.5 Pd/SnO2 showed a Faraday efficiency of 63% for formate at -1.20 V vs. RHE and a current density of 90.59 mA.cm− 2, which were 1.4 and 2.7 times higher than that of pure SnO2, respectively. The modified catalyst grains were refined, and the charge transfer resistance at the catalyst interface was reduced and the electrochemically active area was increased, generating more catalytically active sites and increasing the contact between CO2, electrolyte, and electrode-catalyst. Density-functional theory calculations showed that the doping of Pd element changed the local structure of SnO2, and the Pd/SnO2 surface was more favorable for the generation of the intermediate products *HCOO− and formate as well as the inhibition of hydrogen precipitation, which was consistent with the experimental results.

Published: July 2024

Abstract

The Non-Orthogonal Multiple Access (NOMA) tech-nique, supported by Intelligent Reflecting Surfaces (IRS), is con-sidered a promising solution to enhance the quality of radio com-munication networks. However, as IRS-NOMA wireless networksare increasingly deployed more densely, inter-cell interferencehas become a significant factor limiting system capacity. Thisissue has not been adequately addressed in most existing IRS-NOMA wireless network research. In this paper, we use a randomgeometry approach to model an uplink DIRS-NOMA densewireless system. Specifically, a group of two users (UE) at the celledge communicates with the base station (BS) through a pair ofIRS, without a direct link to the BS. Based on the proposed model,we develop theoretical frameworks and calculate the BS-IRS-UElink channel statistics using a Rayleigh fading distribution. Wederive the probability density function (PDF) and the cumulativedensity function (CDF). Based on statistical data analysis, wederive closed-form expressions for the outage probability (OP),ergodic rate (ER), and bit error rate (BER) of UEs at the BSas functions of the signal-to-interference-plus-noise ratio (SINR).From the obtained results, we evaluate the overall performanceof the system. We also propose an algorithm that optimizesthe sum rate of all users under individual power constraints.This formulated problem requires simultaneous optimization ofpower at the user and phase shift at the IRS and is non-convex.Finally, we verify the mathematical analysis through comparisonswith Monte Carlo simulations. The presented numerical resultsdemonstrate that the proposed solution achieves near-optimalperformance and outperforms the OMA-based solution in termsof sum rate.

Abstract

Gel polymer electrolytes (GPEs) are crucial in quasi solid-state dye-sensitized solar cells (DSSCs) due to their chemical and physical stability, enhanced safety, and improved performance, which boosts ionic conductivity. This study presents the enhancing gel polymer electrolyte properties intended for DSSCs by blending low and high-molar weight variants of the same polymer. Using the hot press method, the synthesized polymer blend electrolyte shows notable DSSC performance improvement. The blend incorporates polyethylene oxide (PEO, MW 4,000,000) and its lower molar weight counterpart, polyethylene glycol (PEG, MW 4,000). The ionic conductivities of the GPEs were assessed via impedance analysis. The GPE with 100% PEG achieved the highest ionic conductivity (10.30 mS cm− 1) but was liquid-like, while 100% PEO showed the lowest conductivity (5.23 mS cm− 1) with a solid-state nature. A blend with a 3:1 PEO to PEG ratio exhibited intermediate conductivity and a gel-like consistency. Utilizing this electrolyte in solid-state DSSCs yielded an extremely high 8.76% power conversion efficiency and a short-circuit current density of 13.80 mA cm− 2. The lowest efficiency was observed for the 100% PEO content. The study demonstrated a significant efficiency improvement of 38.17% and 36.45% in blend polymer electrolyte-based DSSCs compared to single polymer electrolytes with PEO and PEG, respectively. Conductivity in the GPEs followed Vogel-Tamman-Fulcher behavior. The DSSCs utilized N719 dye-sensitized TiO2 nanoparticle multi-layer photoanodes and Pt counter electrodes. The results indicate that combining low and high-molar-weight polymers in the electrolyte significantly boosts DSSC efficiency. Current efforts aim to refine polymer composition and understand the mechanisms behind the efficiency enhancement in mixed-phase gel polymer electrolytes.
