Published: March 2024

The temperature-frequency dependences of the electrical characteristics of Li2 Fe2,5-x Mex O4 (Ме=La;Y, x=0.01; 0.03; 0.05) spinels synthesized by the «sol-gel» autocombustion technology were obtained by the method of impedance spectroscopy in the temperature range of 298-473 K.
Based on their analysis, the main mechanisms of conductivity of these materials in the studied temperature range were identified: hopping and activation, which are competing. The effect of doping lithium-iron spinels with rare-earth metal impurities on these conductivity mechanisms has been investigated. It has been established that the presence of impurities in small concentrations in the synthesized samples significantly decreases their conductivity, mainly due to destruction of the hopping mechanism of electronic conductivity.

To ensure blood safety in blood transfusion service, the practice of donor screening, donor notification and counselling is essential. The aim of the study was to analyse the response rate of notified reactive donors to counselling and to see the impact of donor notification on reactive donors. A observational descriptive cross-sectional study was conducted in the blood centre of department of Transfusion Medicine, MKCG Medical College and Hospital Berhampur, Odisha during the time period from January 2022 to December 2022. Data was collected from reactive blood donor counselling register. Sero-reactive donors were contacted telephonically. Those who turned up into blood centre were counselled again and referred to appropriate centre for further management. The statistical analysis was done using percentages based on descriptive analysis.Out of total 32700 donations over a period of one year, 726 (2.22%) were reactive donors. Out of the total 726 donors, 496 (68.31%) donors could be notified telephonically, rest 230 could not be notified due to several reasons. Out of 496, 352(48.48%) were responders, who were counselled and referred to higher centres for further management. The response rate was 48.48%. Only 24 sero-reactive donors could be followed up. Pre-donation counselling, appropriate TTI screening test, donor notification and post donation counselling all together form a vital link between blood donors and blood safety, however the gap still exists.

In this study, we wanted to correlate the findings of TRUS and MRI with regard to the diagnosis and localization of carcinoma prostate and local staging of carcinoma prostate. Our study included 43 men, with age ranging from 49 to 76 years. They underwent TRUS, MRI and TRUS guided twelve core biopsies after being suspected with prostate cancer based on high PSA values (greater than 4.0 ng /ml) or abnormal DRE findings. This study was conducted from April 2018 -June 2019. Imaging findings were confirmed with histopathology. TRUS used for the detection of malignancy had sensitivity, specificity, PPV and NPV as 69.70%, 80 %, 92% and 44.44 % respectively. The values were 63.16%, 83.33%, 75.00%, and 74.07% for the sensitivity, specificity, PPV and NPV of TRUS respectively for the detection of ECE. rnFor the detection of malignancy, the sensitivity, specificity, PPV and NPV of MRI was 87.88%, 70%, 90.63% and 63.64% respectively and 85.71%, 89.66%, 80.00% and 92.86% for the sensitivity, specificity, PPV and NPV of MRI respectively for detection of SVI. For detection of extracapsular extension (ECE), MRI had sensitivity, specificity, PPV and NPV of 78.95%, 83.33%, 78.95% and 83.33% respectively. When compared to TRUS, MRI is more useful in the diagnosis and accurate staging of prostate cancer. MRI can improve the false-negative biopsies resulting due to the inability of TRUS in detection of abnormal areas.

Published: March 2024

Congenital Mullerian anomalies are associated with higher incidence of reproductive failure and adverse obstetrical outcomes. The new ESHRE classification is a precise way to describe a genital anomaly in simple way. Many genital tract anomalies lead to devastating life-threatening conditions but under-reported and poorly explained. This study aims at finding out those anomalies which more frequently lead to specific diseases needing emergency intervention to save life of the patient. This longitudinal observational study evaluates the diagnosis and treatment of 12 patients with congenital Mullerian abnormalities which led to life threatening emergency with case discussion and pictorial documentation. Among 12 women with uterine anomalies 4 abortions, 7 delivered preterm, 1 term delivery occurred. Majority of complications associated with U3 types (58.3%). Other types with complications are U4 (25%) and U2 (16.7%). Presenting features at emergency varied like mimicking ectopic, labour complications, ruptured corpus, placenta previa and accreta as well as iatrogenic perforation. Presence of congenital uterine anomalies have adverse effect on obstetrical outcome. Majority of complications are associated with U2, U3 & U4. Probably U1 doesn’t interfere with ongoing pregnancy and U5 fails to continue pregnancy. This knowledge warrants the need for a larger case control study to extrapolate these findings to the general population and also to recommend the need for universal Prenatal Screening for uterine anomalies so as to improve the obstetrical outcome in patients with uterine anomalies.

Published: March 2024

Background: Skin color is an important economic trait in black-bone chicken production and it has been identified that the gut microbiota is an important factor in animal health and physiology. However, it is unknown about whether the gut microbiota in black-bone chickens is connected to the coloration of chicken skin. Methods: To investigate the relationship between the gut microbiota and skin coloration, comparing the differentiation of the gut microbiota structure and abundances in black- (B group) and white-skinned (W group) Muchuan black-bone chicken. Here, we characterized the microbiota in the jejunal contents of both the B and W groups using the Illumina MiSeq platform, targeting the genomic V4 region of the 16S rRNA gene. Result: In terms of community richness, the ACE community richness index of the B group was significantly higher than that of the W group (p less than 0.05) and the proportion of unique OTUs was higher in group B than in group W. According to the species annotation and abundance information of all samples at the genus level, Parabacteroides, Faecalicoccus and Alistipes were enriched in group B, whereas Actinomyces, Elstera and Nosocomiicoccus were enriched in group W. In the evolutionary branch diagram, the relative abundances of Enterobacteriaceae (Gammaproteobacteria, Enterobacteriales) were significantly higher in group B than in group W (LDA Score greater than 4). Our data provide a basis for the hypothesis that the discriminating bacterial taxa in gut is associated with the feature variants for skin coloration of Muchuan black-bone chickens, which were fed in the same feed and stocking niches.
El papel del derecho de la Unión Europea en la regulación del trabajo del personal sanitario, especial referencia al caso español
Authors: Iglesia Aza Lidia de la 
Published: March 2024

El personal sanitario tiene un régimen jurídico propio y diferenciado al del resto de los empleados públicos, derivado tanto del sistema de trabajo como de la esencialidad de sus funciones. La normativa de la Unión Europea no tiene un cuerpo legislativo específico para este colectivo, del que ha asumido sus peculiaridades permitiendo el recurso a la excepción en muchas Directivas. Mas allá de la innegable evolución normativa, el régimen interior de diversos Estados Miembros se ha visto afectado por la jurisprudencia del Tribunal de Justicia mediante múltiples cuestiones prejudiciales, clasificables, en virtud de su objeto conforme al tema principal del litigio de origen:
– Tiempo de trabajo.
– Diferencias de trato entre personal con vínculo temporal y con vínculo indefinido.

Published: March 2024

Aim: To evaluate the influence of notebook computers screens and undergraduate level of dental students in the radiographic detection of carious lesions. Methods: Bitewing digital radiographs were presented to 3rd and 5th year dental students in three different notebooks computers: Notebook 1 with anti-glare screen (1366×768 pixels), Notebook 2 without anti-glare screen (1366×768 pixels), and Notebook 3 with anti-glare screen (1920×1080 pixels). A reference standard based on a consensus analysis was set by three senior professors of Oral Radiology and Cariology. Sensitivity, specificity and accuracy values were measured and submitted to two-way ANOVA at a significance level of 5%. Results: Notebook 2 provided significantly lower sensitivity values (Mean 56.5% ± 2.94) than notebook 3 (71.1% ± 2.82) (p = 0.002). We found no statistically significant differences between the two undergraduate years (p > 0.05). Conclusion: The anti-glare screen of notebook computers screens can influence the radiographic detection of carious lesions, but the undergraduate level of dental students does not influence this diagnostic task.

Heterotopic Ossification of Bilateral Hips Post–COVID-19 and Prolonged Immobilization
Authors: van de Langerijt Olaf N. , Groot Olivier Q. , Janssen Michiel M.A. 
Published: March 2024

Case:
A 43-year-old healthy man developed hip pain post–coronavirus disease 2019 (COVID-19) immobilization. Imaging confirmed bilateral bridging heterotopic ossification (HO) of the hips, Brooker Class IV. Bilateral HO caused functional arthrodesis (45° flexion: −20° internal rotation). Bilateral HO resection resulted in almost full mobility at 1-year follow-up (90° flexion; 30° internal rotation).

Conclusion:
Many cases of HO after immobilization for COVID-19 have been reported, but as far as we know, this is the first case report describing surgical intervention as an adequate treatment option for severe restricted mobility caused by HO due to COVID-19–induced prolonged immobilization. Caution and preoperative 3D planning are recommended of HO formation near neurovascular structures.

Published: March 2024

Case:
We present the case of a 54-year-old man who underwent elective hip disarticulation complicated by third-degree burn of the left antecubital fossa requiring skin graft. After careful review, it was determined that “antenna coupling” as a result of electrosurgery was the likely cause. We present an experiment demonstrating this phenomenon.

Conclusion:
Antenna coupling is a real but rare cause of intraoperative burns not previously described in the orthopaedic literature. Care should be taken to avoid coiling or running bovie or other electrosurgical device cords with other metallic cords or corded devices.
How to make manga more interesting to readers: Using lattices derived from rough sets
Authors: Matsui Tetsuya 
Published: March 2024

Abstract

In manga (comics) and Japanese animation, “symbol-base theory,” which has its roots in Azuma’s data base theory, is widely accepted. This theory suggests that the elements of a character can be arbitrarily combined, and the elements of appearance and inner personality correspond one-to-one with each other. Mastui and Gunji showed that a method for deriving lattices from rough sets can be used to disprove symbol-base theory in terms of the impressions readers have of characters. In this paper, I applied this method to manga. I hypothesized that manga that created a non-linear lattice is perceived to be more interesting than manga that created using a linear lattice and that manga created a non-linear lattice is perceived to have characters that are more easily distinguishable than manga created a linear lattice. To verify these hypotheses, I constructed three manga using the software “Koikatsu” and conducted an experiment on the web. All manga have the same story, only the character’s hair and tone are different. Character hairstyle and tone of voice create a linear or nonlinear lattice. Manga 1 and Manga 2 created linear lattices and Manga 3 created non-linear lattice. In the experiment, participants read the manga and were asked questions about their impression of it. After that, I conducted a one-way ANOVA on the results. The manga that did not have a one-to-one correspondence between hairstyle and tone and that created a non-linear lattice was perceived to be funnier than the other manga. Also, this manga had no disadvantages in terms of the perceived readability and the ease of distinguishing characters. These results question symbol-base theory.

Published: March 2024

Abstract
Objectives
Analyze quantitative changes of iris and retinal vessels in diabetic macular edema (DME) after intravitreal anti-vascular endothelial growth factor (anti-VEGF) and evaluate their correlations.
Methods
This was a case-cohort study. A total of 26 eyes of DME patients received anti-VEGF treatments and were reviewed three times of follow-up. Images of iris and retinal vessels were obtained before and after treatment and the area density of the vessel (VAD) and the density of the vessel skeleton (VSD) were quantitatively analyzed.
Results
There was no significant change in the iris VAD after the third injection (p > 0.05), but the VSD of iris decreased (p ＜0.05). Further linear regression analysis showed that the difference between postoperative and pretreatment iris VSD was negatively correlated with baseline(R = 0.793, B = -1.242, p = 0.000), but not with age, sex, and baseline visual acuity (all p > 0.05).
Conclusions
Iris vessels are more sensitive to anti-VEGF than retinal vessels.

Abstract

Both post-mortem and in vivo data argue for dopamine dysfunction in patients with Alzheimer’s Disease (AD). However, the timing and regional progression of dopaminergic systems alterations in AD are still debated. Aim of the study was to investigate in vivo the pattern of dopaminergic changes and connectivity using DAT-SPECT imaging in patients across the AD spectrum. Fifty-nine A + T + N + AD patients (n = 21 MCI-AD; n = 38 AD-DEM) and n = 45 age and sex-matched controls (CG) entered the study and underwent 123I-FP-CIT dopaminergic imaging. The occipital binding was used as reference region to obtain single-subject binding in different brain regions. Between-groups differences in 123I-FP-CIT binding in both mesolimbic and nigrostriatal dopaminergic pathways were assessed using an ANCOVA test-adjusting for the effect of center of imaging acquisition, age, and sex. Regions resulting from the voxel-wise direct comparison between MCI-AD and AD-DEM were considered as a seed of interest for a voxel-wise interregional correlation analysis. Both MCI-AD and AD-DEM patients showed dopaminergic depletion within the basal ganglia, whereas cortico-limbic regions (namely hippocampus, amygdala, anterior and middle cingulate, frontal cortex and thalamus) resulted impaired only in the dementia phase. The brain voxel-wise interregional correlation analysis showed a progressive pattern of disruption of caudate/thalamus dopaminergic connectivity to hippocampus and amygdala from MCI-AD to AD-DEM stages. This study indicates basal ganglia dopaminergic alterations and connectivity disruption in the nigrostriatal and mesolimbic systems already in early stage AD, extending to several cortico-limbic regions in dementia phases.

Abstract

Suicide is a complex behavior strongly associated with depression. Despite extensive research, an objective biomarker for evaluating the suicide risk precisely and timely is still lacking. Using the precision resting-state fMRI method, we studied 61 depressive patients with suicide ideation (SI) or suicide attempt (SA), and 35 patients without SI to explore functional biomarkers of suicide risk. Among them, 21 participants also completed electroconvulsive therapy (ECT) treatment, allowing the examination of functional changes across different risk states within the same individual. Functional networks were localized in each subject using resting-state fMRI and then an individualized connectome was constructed to represent the subject’s functional brain organization. Compared to patients without SI, patients with suicide risk showed hyper-connectivity involving the frontoparietal network (FPN, p = 0.001). ECT treatment normalized these hyper-connections, with connectivity between the FPN and limbic system (LMB) showing the most significant reduction (p < 0.001). Post-hoc analysis indicated that the FPN-LMB connectivity was also significantly altered in the SA group compared to the SI group (p = 0.001), which may reflect the elevation of suicide risk across these two groups. These findings suggest that functional coupling between the FPN and LMB may constitute an important biomarker for evaluating suicide risk and may provide potential targets for interventions such as non-invasive brain stimulation.
