Abstract

Aiming at the problem that the working state of the boring bar cannot be observed in the closed environment during deep hole boring processing, this study designs a multiparameter state monitoring system for the boring bar in the cutting process. The main idea of this monitoring system is to use the piezoelectric effect of the strain gauge in the sensor to measure the change of the voltage, and to obtain the three-way cutting force, the tooltip displacement, the vibration velocity, and the vibration acceleration through the voltage. To realize the online monitoring of multiparameter state in the cutting process, the stress model of the boring bar is established, and the stress analysis is carried out. The overall structure of the online monitoring system is established, and then the various parameters obtained by voltage are analyzed and calculated. The experimental platform of multiparameter state monitoring of the boring bar is built. The monitoring results of the multiparameter state monitoring system and commercial measurement system in the cutting process are compared by boring experiments. The results show that the error of three-dimensional cutting force and vibration acceleration is within 10%, and the error of tooltip displacement fluctuates around 15%, which verifies the feasibility of the monitoring system in the boring process.

Abstract

Objectives
Unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) is a new minimally invasive technique for intervertebral fusion under full endoscopy. We conducted a comprehensive comparative analysis with another minimally invasive technique (minimally invasive transforaminal lumbar interbody fusion, Mis-TLIF) in terms of surgical trauma, clinical outcomes, laboratory indicators.
Methods
A retrospective analysis of clinical and imaging data of 77 patients with lumbar degenerative illnesses(37 underwent UBE-TLIF, 40 underwent Mis-TLIF) was performed. Demographic data, clinical outcomes [visual analog scale (VAS) for back and leg pain, Oswestry Disability Index (ODI)], operative data (total operation time, intraoperative blood loss, postoperative drainage, length of hospital stay), and laboratory results [plasma hemoglobin (HB), serum creatine phosphokinase (CPK), and C-reactive protein (CRP) ] were compared between the two groups, The Macnab score, fusion rate and fusion time, and complications were also recorded.
Results
Both groups experienced significant improvements in VAS for back and leg pain and ODI scores after surgery (P < 0.05). The VAS-Back and ODI scores were significantly better in the UBE-TLIF group than in the Mis-TLIF group at 1 week and 1 month after surgery (P < 0.05). Although the total operation time was significantly longer in the UBE-TLIF group (P < 0.01), the intraoperative blood loss, postoperative drainage and decrease in hemoglobin level were significantly higher in the Mis-TLIF group (P < 0.01). A difference was observed in the fusion time (P < 0.05). There were no between-group differences for the fusion rate, postoperative complications, excellent and good rates and hospital stay (P > 0.05). Serum CRP and CPK levels were considerably lower in the UBE-TLIF group than in the MIS-TLIF group after surgery (P < 0.01).
Conclusions
Both UBE-TLIF and Mis-TLIF have equivalent and favorable clinical outcomes. UBE-TLIF is better in reducing surgical bleeding and rapidly improving postoperative back pain.

Abstract

Recent reports have shown that pre-treatment low muscle mass may lead to poorer outcomes for cancer patients. We explored the correlation between Visceral Adipose Tissue (VAT), Subcutaneous Adipose Tissue (SAT), and Muscle Mass (MM) as measured by CT scans, and overall survival (OS) following diagnosis of colorectal cancer (CRC). We conducted a retrospective review of medical records and CT scans of patients diagnosed with CRC between 2007–2018. Demographics, pathology, and clinical parameters were collected. Using Image-J software, we measured VAT, SAT, and MM. Survival rates were analyzed using Kaplan-Meier curves, and prognostic factors were assessed using multivariate Cox regression. Analysis included 408 patients with a mean age of 56.9 years and a median follow-up of 93.3 months. Colon and rectum/rectosigmoid colon cancers were equally distributed. The 5-year OS rate was 67.8%. There was no significant difference in OS rates based on SAT or VAT. However, higher MM was associated with a improved 5-year OS rate. Factors such as age, stage, grade, and surgery were also associated to OS rates. These findings suggest that higher muscle mass may lead to better outcomes for CRC patients, highlighting the potential impact of exercise and nutritional interventions on patient outcomes.

Published: June 2024

Abstract

Purpose
This systematic review aimed to analyse the effects of active video games (AVGs) on psychology among overweight and obese adolescents.
Method
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement guidelines were used to search the PubMed, SCOPUS, EBSCOhost (SPORTDiscus), and Web of Science databases for studies published in the last 10 years (2013–2023). Keywords related to psychology, being overweight or obese, and adolescents were used. From the 713 studies, 10 fulfilled all eligibility criteria and were included in this review.
Results
The study results revealed that AVGs could positively impact the psychological well-being. However, due to different experimental designs, experimental environments, experimental objectives, and game consoles, the results of self-efficacy, social and peer support, and self-esteem are still conflicting. Additionally, due to measurement issues, quality of life has not yielded a positive effect.
Conclusion
Future research should standardise methods and look into the underlying mechanisms to come up with personalised plans for improving the psychology of overweight and obese adolescents who are involved in AVG interventions as part of health promotion programmes.

Abstract

Aims
To explore the rare and difficult cases of undifferentiated embryonal sarcoma of the liver (UESL) in children in a single center, summarize the diagnosis and treatment experience and analyze the role of the computer-assisted surgery system (Hisense CAS), providing a new global vision and three-dimensional perspective.
Methods
We retrospectively collected the clinical data, diagnosis, and treatment process of children with UESL confirmed by histopathological examination in our hospital from January 2009 to December 2020. The relationship between the tumor and important blood vessels, liver and tumor volume, as well as other three-dimensional characteristics in the three-dimensional model reconstructed by Hisense CAS were analyzed. The findings from this analysis help in making surgical decisions and preoperative planning.
Results
Four children with UESL were included in the study, comprising of 3 girls and 1 boy. The age of onset ranged from 6 to 8 years. All four children presented with symptoms of abdominal discomfort, and abdominal masses were detected during physical examination. Due to the urgent wishes of their parents and the possibility of a benign disease, all four children underwent one-stage radical surgery. In Case 1, three-dimensional reconstruction was not performed during the initial diagnosis, which made it challenging to accurately evaluate and plan the preoperative procedure. Case 2 presented additional challenges as the tumor was located in the middle lobe of the liver and involved the first and second hepatic hilum. Case 3 faced difficulties in the pathological diagnosis of the tumor after surgery, but eventually, the diagnosis was confirmed through histochemistry and consultation with higher-level hospitals. Case 4 had a gaint tumor, and the preoperative simulated future liver remnant volume (FLV) accounted for 21.0% of the total volume of liver and tumor (TLTV). According to the standard liver volume (SLV) for children, the FLV accounted for 77.0% of the SLV, making surgery feasible. Although all four children underwent complete resection, Case 4 experienced recurrence below the diaphragm 19 months after surgery. Currently, the 3-year overall survival rate stands at 100%.
Conclusion
UESL in children is clinically rare, and the key to diagnosis and treatment lies in complete surgical resection. By utilizing individualized three-dimensional surgical planning, accurate and complete resection of difficult and complex UESL cases in children can be achieved, leading to a favorable prognosis.

Abstract

To address the issues of surface roughness and spheroidization in the internal channels of additively manufactured high-temperature alloys with a large aspect ratio, a study on abrasive water jet polishing using synthetic silicon carbide was conducted. A full factorial experimental design was employed to explore the effects of three sets of process parameters: polishing pressure, abrasive concentration, and polishing time, on the quality of the channel surfaces. Additionally, the finishing effects of two different abrasive grain sizes under these parameters were compared. A generalized factorial regression model was constructed, which indicated that the significant factors affecting the surface quality of the channels were, in order, pressure, concentration, and time. An analysis of the process parameters and measurement data was carried out, determining the optimal polishing parameters for the internal channels. The surface characteristics of the runners were analyzed using surface morphology. The experiments clearly enhanced the finishing and surface quality of internal runners in additively manufactured high-temperature alloys, effectively solving the problem of spheroidization that occurs during the printing process of additive metal components.

Abstract

Background
Dementia prevention has emerged as a critical health concern. Nevertheless, the association between long-term physical activity and risk of dementia remains inconclusive, especially among geriatric patients with depression. We aimed to explore the association between long-term physical activity, following the diagnosis of geriatric depression, and risk of dementia, including Alzheimer’s disease, vascular dementia, and Lewy body dementia.
Methods
This was a nested case-control study. The participants were aged ≥ 60 years, diagnosed with geriatric depression, and had attended outpatient clinics at least three times. Data were obtained from the Korea National Health Insurance Service-Elderly Sample Cohort (January 1, 2002, to December 31, 2019). Each case was matched with up to five controls based on age, sex, date of depression diagnosis, and duration of follow-up. Long-term physical activity was assessed using two methods: adherence to World Health Organization recommendations and the total amount of physical activity measured in metabolic equivalents of task (MET)-min per week.
Results
A total of 12,022 participants, including 2,121 patients (17.6%) and 9,901 controls (82.4%), met the inclusion criteria. The mean follow-up period was 4.96 years. Among physically active individuals who adhered to WHO recommendations, a significantly reduced risk of dementia was observed. Additionally, a dose-dependent decline in the risk of dementia was observed. Analyses based on MET-min/week revealed a significantly lower risk in the top quartile, with a dose-dependent reduction. In subgroup analyses, a higher risk of dementia with a dose-dependent decrease was observed in men, individuals aged 70–79, and antidepressant users.
Conclusions
This study highlights an association between engaging in physical activity and a decreased risk of dementia in individuals newly diagnosed with geriatric depression. Consequently, encouraging geriatric patients with depression to participate in physical activity to prevent dementia is important.

Abstract

Awash River is one of the exhaustively utilized and economically viable basin in Ethiopia. The river basin is classified into six planning areas namely Upper Awash, Halidhege, Awash Awash, Adaytu, Terminal and Eastern parts. This study investigates the spatial and temporal variability of available water in the River Basin using the WEAP model. Future scenarios are based on pre-determined government plans, utilizing climate data from 1977 to 2020 and discharge from 1999 to 2020. The focus is on six planning areas within the Awash River Basin. Results reveal a severe water shortage in the Upper Awash planning area, a vibrant economic hub in the country. While the proposed Dam at Melka Kunture may mitigate the gap by 2030, additional water supply options are needed to address projected gaps of -236.7 MCM in 2030 and − 712 MCM in 2080. The possible mitigation plan includes water storage infrastructures such as constructing reservoirs, implementing water harvesting structures, and utilizing groundwater resources. While the Halidhege planning area requires special attention, lacking proposed dams or studied water supply options. Water gaps are projected to be -53 MCM in 2050 and − 761.2 MCM in 2080. Potential solutions involve small-scale water harvesting, reservoir construction, and groundwater utilization. The Eastern Planning area, covering the largest portion of the Awash Basin, faces water shortages throughout the study periods. Minimal rainfall and elevated temperatures exacerbate the strain on limited water resources. Projected water gaps are − 112.1 MCM, -79.4 MCM, and − 297.6 MCM in 2030, 2050, and 2080, respectively. The study emphasizes the importance of additional water supply options, such as immediate water harvesting structures, long-term reservoirs, and appropriate groundwater utilization, to bridge the projected water gaps and ensure sustainable development in the Basin.

Abstract

Assessing biodiversity in protected areas is crucial. However, conventional methods for estimating species richness can lead to inaccurate assessments of biodiversity in these regions. To address this, we present a complementary approach to assess potential species richness at a finer resolution (1 km) in the special conservation area of Montesinho/Nogueira (SAC-MN; Portugal), based on a spatial and temporal estimates of species richness trends over time (2001–2021). We compiled 10,190 species occurrence records from four taxonomic groups: amphibians, reptiles, birds, and mammals. We created correlative ecological niche models (MaxEnt) with a time series of satellite-remote sensing variables (SRS-ENMs) using solely Google Earth Engine (GEE). We calculated annual potential species richness (PSR) maps by stacking the SRS-ENMs and identified positive and negative trends with the Mann-Kendall test. Individual species’ SRS-ENMs indicated distinct habitat suitability within SAC-MN over time. The eastern and western boundaries of SAC-MN revealed an increase in PSR, while the central area indicated PSR declines. Each group displayed different trends in PSR: birds and mammals were more similar between them than amphibians and reptiles. This approach serves as a valuable instrument for ecologists and conservationists, assisting in evaluating PSR and trends over time using remote sensing. Furthermore, it provides meaningful insights for subsequent analysis in order to inform decision-makers and other stakeholders to enhance local biodiversity conservation efforts.

Abstract

Objective:Little research hasn't been done on the connection between immune cells and osteoarthritis. To investigate the pathogenic and protective roles of immune cells in osteoarthritis risk, Mendelian randomization was employed in this study.Method:The study employed a two-sample Mendelian randomization methodology to determine the causal relationship between 731 immune cells and osteoarthritis. The exposure was genome-wide association research including 731 immune cells, and the outcome was seven distinct osteoarthritis phenotypes: osteoarthritis at any site, knee, hip, spine, hand, thumb, and finger. Causal estimates were calculated using inverse variance weighting. In addition, MR-Egger, weighted median, weighted mode, and simple mode were used to ensure reliability. In addition, methods including the Cochran Q, leave-one-out, MR-Egger intercept, and MR-Presso tests were used for sensitivity analyses. R software was used for all statistical analyses.Result:166 suggestive relationships between 731 immune cells and various osteoarthritischaracteristics were found in the MR study. Upon applying the Bonferroni correction to the original screening of 166 immune cells, we discovered that eight immune cells had a strong causal relationship with six osteoarthritis phenotypes. Furthermore, a bidirectional causal link between the six immune cells and the six osteoarthritisphenotypes was discovered by a reverse MR analysis.Conclusion:Based on our study, the immune cells and mechanisms identified may be valuable immune markers for clinical screening and prevention of osteoarthritis. They may also be potential targets for future therapeutic drug discovery.

Published: June 2024

Abstract

Agricultural activities affect tropical forest biodiversity; however, some bat species can survive under these anthropogenic changes. We described the characteristics of phyllostomid bat assemblages in tree covers located in 48 plots among four agricultural landscapes of northwestern Ecuador. Bats were captured with mist nets installed at a ground level reaching three meters’ height. For each of the plots, we installed a mist net in four forms of tree cover (polyspecific live fences, monospecific live fences, cacao plantations, and isolated trees in pastures). We captured 250 phyllostomid bats belonging to 16 species with a trapping effort of 19,200 m2 of net coverage. Polyspecific live fences showed significant differences in relative abundance, richness, and diversity of phyllostomid bats compared to the other three. Frugivorous and nectarivorous guilds were the most abundant, and also exhibited the highest richness among other guilds present in agricultural landscapes. We conclude that living fences composed of various plant species favor the abundance, richness, and diversity of phyllostomid bats. In addition, frugivorous, and nectarivorous guilds increase their abundance and richness in agricultural landscapes, while the animalivorous guild is negatively affected. We recommend installing polyspecific live fences in tropical production systems to support the conservation of phyllostomid bats.

Abstract

Objective Given the increasing significance of digital health literacy (DHL) and health literacy (HL) in promoting informed decision-making and healthy behaviors, this study aimed to assess the influence of self-reported HL and DHL on treatment adherence and quality of life among patients who underwent transurethral resection of bladder tumors (TUR-BT) for primary non-muscle invasive bladder cancer (NMIBC).Materials & Methods This observational research involved 107 NIMBC participants. Before the procedure, the patients' DHL and HL were evaluated using the European Health Literacy Survey Questionnaire short version and the eHealth Literacy Scale. Six months after surgery, we surveyed patients’ QoL using the EORTC QLQ-C30. In line with recommendations from the European Association of Urology guidelines, adherence to the treatment plan was assessed along with a follow-up cystoscopy examination for each patient.Results Multivariate analysis revealed that poorer DHL and HL were significantly associated with older age (p < 0.001), lower educational attainment (p < 0.001), and lack of internet access (p < 0.001). Conversely, higher DHL and HL levels were positively correlated with increased treatment adherence, as measured by cystoscopy completion (p < 0.001). Additionally, logistic regression analysis demonstrated significant associations between improved DHL and HL scores and better global health status (DHL, p = 0.022; HL, p = 0.008), higher emotional status (p < 0.001 for both), and social functioning (p < 0.001 for both). Notably, there were no significant differences in the symptom scale scores between the DHL and HL groups.Conclusion To the best of our knowledge, this is the first study to explore the specific effect of HL/DHL on QoL and adherence in this patient population. Our research suggests that there may be a link between self-reported levels of DHL/HL and treatment adherence as well as QoL among patients with NIMBC.
