Abstract

Objective
To detect the appropriate fluoroscopic angle of intraoperative C-arm X-ray based on precise femoral neck anatomy.
Methods
The femoral neck was divided into the anterior, posterosuperior and posteroinferior surfaces. These surfaces and the coronal plane of the femur formed anterior surface coronal angle (ACA), posterosuperior surface coronal angle (PSCA) and posteroinferior surface coronal angle (PICA), respectively. The three angles of 32 dried femoral specimens were measured. The femoral neck wall attached with steel wire wind aluminum foil model and three Kirschner wires perforating femoral neck wall model were prepared. The C-arm was rotated every 5° to complete the 0° -180 ° fluoroscopy of each curved surface. 111 frames of images were obtained for each femoral specimen. The appropriate fluoroscopic angle of each surface was obtained, and the fluoroscopic images characteristics of Kirschner wire penetrating the femoral neck cortex on three appropriate fluoroscopic angles and the anteroposterior and lateral fluoroscopy were observed.
Results
The femoral neck is irregularly cylindrical with the anterior surface is longer than the posteroinferior surface, and the posterosuperior surface is the shortest. The measurement data of ACA, PSCA and PICA were (31±4.589)°, (67.813±5.052)° and (168.688±3.206)°, respectively. The appropriate fluoroscopic angle of the anterior, posterosuperior and posteroinferior surface of the steel wire aluminum foil model were (30.781±5.464)°, (67.969±3.721)°, (167.813±4.319)°, respectively. And there was no significant difference with the measurement data of the corresponding surface coronal angles, P > 0.05. The model of wire penetrating the femoral neck wall showed that the Kirschner wire penetrating the femoral neck could not be fully exposed in the traditional anteroposterior and lateral view films. Increasing the appropriate fluoroscopic angle of 30°, 70° and 170° could clearly find the Kirschner wire penetrating the cortex.
Conclusion
Traditional anteroposterior and lateral fluoroscopy cannot accurately show the true structure of femoral neck. Additional 30°, 70° and 170° fluoroscopy can accurately observe the fracture reduction quality of the anterior surface, posterosuperior surface and posteroinferior surface of the femoral neck and the damage to the corresponding cortical bone caused by internal fixation.

Abstract
Background
POEMS syndrome is an extremely rare hematologic malignancy. This study describes the baseline and clinical characteristics of 11 patients with POEMS syndrome to provide a deep insight into the disease and explore efficient methods of diagnosis and treatment.
Method
From October 2020 to January 2023, a retrospective observational study was conducted on 11 patients with POEMS syndrome diagnosed in the First Hospital of Shanxi Medical University. Clinical and diagnostic data were collected from the electronic medical records of these patients.
Results
We enrolled 11 patients in this study (81.8% male, 18.2% female, median age 57 years). The median time from the onset of symptoms to diagnosis was 5 months. All patients had a peripheral neuropathy. The electromyogram of patients (81.8%) indicated both myelin and axonal injury. Lymphadenopathy (73%), splenomegaly (64%), and the hepatomegaly (9%) were detected on examination. Thyroidal (72.7%), gonadal (22.2%), and adrenal gland (62.5%) malfunctioning were the most frequent types of endocrinopathy. 72.7% of patients had normal serum immunoglobulin and the levels of M protein were relatively low. The type of M protein in these patients consisted of IgA-λ (45.5%), IgG-λ (36.4%), and λ light (9.1%) chains. All patients underwent single-photon emission computed tomography/computed tomography (SPECT/CT) and the detection rate of bone lesions was higher than other studies from China (36% vs. 27%). In addition, dyslipidemia was significant and 45.5% of patients had reduced total cholesterol levels.
Conclusions
POEMS syndrome is a rare plasma cell neoplasms with low tumor burden, insidious onset, and diverse and nonspecific clinical manifestations. Immunofixation electrophoresis (IFE) and free light chain (FLC) assays are essential for detecting of M protein and diagnosing the of this disease. Bone SPECT/CT can be helpful in detecting bone lesions. Our finding indicated that patients with POEMS syndrome have hypocholesterolemia, which may be a novel biomarker for assessing the disease progression and prognosis.

Abstract
Burnout is a work-related mental and physical syndrome resulting from long-term exposure to emotional and interpersonal stressors. Despite widespread burnout and a paucity of studies examining the precise patterns of burnout in this field, Medical Laboratory Professionals may be impacted by extended exposure to extreme stress. The study aimed to assess the magnitude of burnout and associated factors among Medical Laboratory Professionals in public hospitals of Jimma zone, southwest Ethiopia, from May 1 - June 1, 2022. Methods and Material: An institutional-based cross-sectional study was conducted, on 153 study participants. Data was collected using a pretested self-administered questionnaire and then verified, encoded, entered with EPI INFO Version 7, and analyzed using SPSS Version 21.0. Results: A total of 153 people participated in this study. The average age was under 29 years, at 89 (58%), with a standard deviation of (29.95 ± 4.2). 36 respondents, or 30.1%, said they were highly burned out. The multivariate logistic regression analysis revealed a statistically significant association between burnout and daily cigarette use [(AOR = 1.74, 95% CI (0.94 to 3.91)], drug abuse [(AOR = 0.083, 95% CI (0.034–0.247)], insufficient sleep [(AOR = 0.237, 95% CI (0.098–0.643)], and lack of a family relationship [(AOR = 4.73, 95% CI (1.82–7.324)]. Conclusion and recommendations: Drinking alcohol, abuse of drugs, smoking cigarettes for several days, lack of adequate sleep, and not having a family relationship were significant predictor variables for burnout in Medical Laboratory Professionals. The results support the development of interventions to enhance mental health and additional research.

Abstract
Terrestrial gravity perturbations caused by seismic fields produce the so-called Newtonian noise in gravitational-wave detectors, which is predicted to limit their sensitivity in the upcoming observing runs. In the past, this noise was seen as an infrastructural limitation, i.e., something that cannot be overcome without major investments to improve a detector's infrastructure. However, it is possible to have at least an indirect estimate of this noise by using the data from a large number of seismometers deployed around a detector's suspended test masses. The noise estimate can be subtracted from the gravitational-wave data; a process called Newtonian-noise cancellation (NNC). In this article, we present the design and implementation of the first NNC system at the Virgo detector as part of its AdV+ upgrade. It uses data from 110 vertical geophones deployed inside the Virgo buildings in optimized array configurations. We use a separate tiltmeter channel to test the pipeline in a proof-of-principle. The system has been running with good performance over months.

Abstract

Groundwater is a crucial resource for human activities, and it is vital to establish criteria for radioactivity in its water quality parameters to ensure sustainable use and protect the health of the surrounding population. In line with the sanitary standards for drinking water and comprehensive discharge standards for sewage, we conducted tests on 12 water samples collected from the densely populated area of the eastern Gonghe Basin. The detected parameters included the activity levels of U, Th, 226Ra, 40K, and gross-α and gross-β. The groundwater in this area exhibited a gross-α activity concentration ranging from 0.06 to 1.19Bq/L, with an average value of 0.32Bq/L. The gross-β activity concentration ranged from 0.06 to 1.26Bq/L, with an average of 0.27Bq/L. Notably, the QNH and ZCS water samples were obtained from high-temperature hot springs, and the concentration of gross radioactive α activity exceeded both the Class III water radioactivity index of the Groundwater Quality Standard and the limit specified by the drinking water Sanitation Standard. Additionally, the 230Th, 226Ra, 210Po, and 232Th mononuclide α radioactivity in these two groups of water samples surpassed the personal radiation dose limit for drinking water. The radioactivity content of other water samples was low on the whole, which met the relevant standards. However, the internal exposure dose of 210Po, caused by natural alpha radionuclides XTM-1, STM-1, STM-2, and GH-02, slightly exceeded the limit. The estimated internal exposure dose due to natural beta radionuclides in the water samples taken in this study did not exceed the World Health Organization standard for personal radiation dose in drinking water by 0.1mSv/a. This study enhances our understanding of the distribution and causes of groundwater radioactive concentration in the Gonghe Basin. It also has significant implications for the prevention and control of radioactive water pollution and associated health risks.

Abstract
A fluctuating flow type photocatalytic reactor was used to investigate the degradation of Rhodamine B on a large scale. The effect of initial dye concentration and operating solution pH on the degree of Rhodamine B degradation has been studied. The Rh B dye degradation is larger at a lower solution pH (pH 2) than at a higher pH and at a lower initial (20 ppm) dye concentration. The degradation of rhodamine B in the presence of process-intensifying additives like hydrogen peroxide and Fenton reagent was found to be greater than that reported in the presence of photocatalysts TiO2, ZnO, and CaO. The amount of degradation was reported to be 83.3% at optimum loading of TiO2 (1 g/L), while it was 76.2% at 1.5 g/L ZnO and 65.9% at 1.5 g/L CaO. Titanium dioxide is the most effective photocatalyst among all of the photocatalysts used in this investigation. Among all processes investigated in this study, the combined UV/Fenton process had the highest degradation of 94.8% and the highest COD removal of 68.4%. TiO2 (58.3%) eliminated the most COD during the fluctuating photocatalytic reactor flow, followed by ZnO and CaO. Overall, combined UV/Fenton operation demonstrated the maximum efficacy when utilizing a zig zag flow photocatalytic reactor.

Published: November 2023

Abstract
This study employed deep learning techniques to accurately classify TI-RADS category 4 thyroid nodules as either benign or malignant, and developed a nomogram that incorporated relevant clinical factors. A total of 500 patients were included and randomly divided into a training group (350 patients) and a test group (150 patients). The YOLOv3 model was constructed and evaluated using various metrics, achieving an 84% accuracy in classifying TI-RADS category 4 thyroid nodules. Based on the model's predictions, clinical data, and ultrasound data, a nomogram was developed. The nomogram exhibited superior performance in both the training and testing groups. Additionally, the calibration curve demonstrated good agreement between predicted probabilities and actual outcomes. Decision curve analysis further confirmed that the nomogram provided greater net benefits. Ultimately, the YOLOv3 model and nomogram successfully improved the accuracy of distinguishing between benign and malignant TI-RADS category 4 thyroid nodules.

Published: November 2023

Abstract
As a cross-camera retrieval problem, person Re-identification (ReID) suffers from image style variations casued by camera parameters, lighting and other reasons, whic-h will seriously affect the model recognition accuracy. To address this problem, this paper proposes a two-stage contrastive learning method to gradually reduce the impact of camera variations. In the first stage, we train an encoder for each camera using only images from the respective camera. This ensures that each encoder has better recognition performance on images from its respective camera while being unaffected by camera variations. In the second stage, we encode the same image using all trained encoders to generate a new combination code that is robust against camera variations. We also use Cross-Camera Encouragement distance that complements the advantages of combined encoding to further mitigate the impact of camera variations. Our method achieves high accuracy on several commonly used person ReID datasets, e.g., achieces 90.8% rank-1 accuracy and 85.2% mAP on the Market1501, outperforming the recent unsupervised works by 12+%.

Abstract
Purpose: Evaluation and comparison of anterior segment parameters before and after uncomplicated phacoemulsification surgery using the Sirius–Scheimpflug system in patients with and without pseudoexfoliation.
Methods: This retrospective study included 35 eyes of 35 patients without pseudoexfoliation who underwent phacoemulsification surgery (Group 1) and 40 eyes of 37 patients with pseudoexfoliation who underwent phacoemulsification surgery (Group 2). Anterior segment parameters of the patients were evaluated preoperatively and at 1 week, 1 month, 3 months, and 6 months postoperatively using the Sirius–Scheimpflug device. Central corneal thickness (CCT), anterior chamber volume (ACV), anterior chamber depth (ACD), anterior chamber angle (ACA), and corneal volume (CV) values were evaluated.
Results: Significant difference was observed between the preoperative and postoperative 1st week, 1st month, 3rd month, and 6th month values of ACA and CV between patients with pseudoexfoliation and the control group (p< 0.05). In CCT measurements, the difference between the preoperative and postoperative values at 1 week and 1 month was significant (p < 0.05), whereas no significant difference was found between the values at 3 months and 6 months.
Conclusion: Phacoemulsification surgery results in a significant reduction in intraocular pressure, an increase in ACD, ACH, and CV, and a widening of the ACA. In patients with pseudoexfoliation, the change in parameters is more dramatic due to the stress exerted on the endothelium by the exfoliative material. When comparing patients with pseudoexfoliation to normal subjects, significant differences were observed, both preoperatively and postoperatively, particularly in CCT, ACA, and CV values.

Abstract

Different commercially available culture media have been in use for the isolation and identification of microorganisms for many years. However, the high cost and limited availability culture media has been a problem in the local market of Tigray, Ethiopia that hinder researchers from carrying out their study. Therefore, the present study aimed to develop locally available cheap plant-based culture medium from cactus pear (Opuntia ficus-indica) cladodes extract for the growth of Lactobacillus species. For this purpose, free external injuries of cactus pear cladode samples were collected from the vicinity of Adigrat, Tigray, Ethiopia. For the test two Lactobacillus species (Lactobacillus reuteri and Lactobacillus mali) were used. The growth of Lactobacillus species on cactus pear cladode agar and broth (4:100, 4:200 and 4:300 w/v) were evaluated and compared with de Man, Rogosa, and Sharpe (MRS) medium. All prepared cactus pear cladode agar (CPCA) media were transparent and free from particles and turbidity. Both tested Lactobacillus species were produced small, white and round colonies on CPCA at 72 hours without bad odor and any pigments. Exponential growth was observed in cactus pear cladode broth (4:200 w/v) in short time than other cactus pear cladode broth (4:100 and 4:300 w/v) medium. When compared with MRS medium (control), the colony counts of Lactobacillus species in cactus pear cladode broth (4:200 w/v) medium did not differ significantly (P < 0.05). The present study clearly showed that the cactus pear cladode (4:200 w/v) medium could be used as alternative culture medium to support growth of Lactobacillus species.

Abstract
Large skin wound is one of the most important health problems in the world. Skin wound repair and tissue regeneration is a complex process involving many physiological signals, and effective wound healing remains a huge clinical challenge. Therefore, there is an urgent need for a strategy to rapidly kill bacteria, promote cell proliferation and accelerate wound healing. At present, electrical stimulation (ES) is often used in clinical treatment of skin wound, which can simulate endogenous biological current of the body and accelerate the repair process of skin wound. However, a single ES strategy is difficult to cover the entire wound area, which may lead to unsatisfactory therapeutic effect. To overcome this deficiency, it is essential to develop a collaborative treatment strategy that combines ES with other treatments. In this study, gold nanoparticles and antibacterial peptides Os were loaded on the surface of poly(lactic-co-glycolic acid) (PLGA) material through the reducibility and adhesion of polydopamine (PDA), and realized the improvement of the electrical activity, anti-inflammatory, antibacterial and biocompatibility of the polymer material. At the same time, this composite membrane material (Os/Au-PDA@PLGA) combined with ES was used in wound therapy to improve wound healing rate. The results show that the new wound repair material has good biocompatibility and can effectively promote cell proliferation and migration. Through the combined application of gold nanoparticles and antibacterial peptides Os, the polymer materials have more efficient bactericidal and antioxidant effects. The antibacterial experiment results showed that gold nanoparticlescould further enhance the antibacterial activity of antibacterial peptides. Furthermore, the Au/Os-PDA@PLGA compositemembrane has good hydrophilicity and electrical activity, which can provide a more favorable cell microenvironment for wound healing. In vivo studies using a full-layer defect model in rats showed that the Au/Os-PDA@PLGA composite membrane had a better therapeutic effect than the pure PLGA material. More importantly, the combination of Au/Os-PDA@PLGA composite with ES significantly accelerated the rate of vascularization and collagen deposition, and promoted wound healing, compared with non-ES controls. Therefore, the combination of Au/Os-PDA@PLGA composite membranewith ES may provide a new strategy for the effective treatment of skin wound.

Abstract

Objective: To explore the characteristics of risk factors in children with CP, focusing on the effects of single risk factors and the number of risk factors on the classification, GMFCS, and comorbidities of CP.
Methods: The medical records of children with CP hospitalized from 2015 to 2023 were reviewed. The effects of nine risk factors, such as Hyperbilirubinemia, asphyxia, and HIE, on the classification, GMFCS and comorbidity of CP were studied.
Results: Among the 536 children with CP, 476 (88.8%) had obvious risk factors. Preterm birth or/and low birth weight was the most common risk factor 243 (45.3%). Children with CP combined with two risk factors were the most common, 147 cases (27.4 %). The number of risk factors in children with CP existing with epilepsy and/or hearing impairment seemed to have fewer risk factors, but existing with spastic quadriplegia was more likely to have more risk factors (≥4). If children with CP had 1-6 risk factors, the intellectual disability and GMFCS≥Ⅳ were more common in the various number of risk factor groups, but spastic hemiplegia and ataxia were less common.
Conclusion: Risk factors were more common in children with severe classification, high levels of GMFCS, and intellectual disability.
