Solution of the inverse problem of estimating particle size distributions
Authors: Escobar Vázquez Milton Alejandro , Reyes Mora Silvia , Cruz Felix Angel Sinue
Published: March 2024

In this work, we describe two alternative methods for solving the ill-conditioned inverse problem that allows estimating the particle size distribution (PSD) from turbidimetry measurements. The first method uses the inverse Penrose matrix to solve the inverse problem in its discrete form. The second method consists of replacing an ill-posed problem with a collection of well-posed problems, penalizing the norm of the solution, and it is known as the Tikhonov regularization. Both methods are used to solve a synthetic application of the inverse problem by solving the direct problem using a theoretical expression of the distribution of particles sizes function f(D) and considering soft industrial latex particles (NBR), with average particle diameters of: 80.4, 82.8, 83.6, and 84.5 nm; and three illumination wavelengths in the UV-Vis region: 300, 450, and 600 nm. The estimated solution obtained by the inverse Penrose matrix is different from the original solution due to the inverse problem is ill-conditioned. In contrast, when using Tikhonov’s regularization, the estimate obtained is close to the original solution, which proves that the particle size distribution is adequate.
Synovial Fluid Proteomics and Serum Metabolomics Reveal Molecular and Metabolic Changes in Osteoarthritis
Authors: Yadav Pramod
Published: March 2024

Background: Osteoarthritis (OA) is a common joint disorder with a complex and multifactorial pathogenesis. Proteomics analysis using two-dimensional gel electrophoresis (2DE) and mass spectrometry (MS) enables high-throughput identification of differentially expressed proteins related to OA. However, the etiology, pathophysiology, and early diagnostic markers of OA are still poorly understood. Methods: Synovial fluid protein biomarkers were compared between OA patients and healthy controls. It was fractionated using DEAE cellulose and Sephadex G-200 columns, followed by SDS‒PAGE and 2D-PAGE for visualization and identification. Mass spectrometry and Mascot were used for protein analysis, and serum metabolite profiles were also investigated using 1D 1H CPMG NMR spectra. Multivariate data analysis, including PCA and PLS-DA, was performed to detect metabolic differences between groups. Results: Proteomics analysis revealed differential expression of synovial fluid proteins, such as serine protease inhibitors, complement components, and apolipoproteins, which may be involved in inflammation and cartilage breakdown. Additionally, serum metabolite profiles differed significantly between OA patients and controls, involving amino acid, lipid, glucose, and energy metabolism. The pathway analysis indicated disruption of the metabolic pathways associated with these metabolites. Conclusions: This study provides insights into the molecular and metabolic changes in OA. Protein biomarkers and serum metabolite alterations enhance the understanding of OA pathogenesis and offer potential opportunities for early diagnosis and disease management. Further validation and translation of these findings into clinical applications are needed for improved OA detection and intervention strategies.

OBJECTIVE

Neurosurgery has remained relatively homogeneous in terms of racial and gender diversity, trailing behind national demographics. Less than 5% of practicing neurosurgeons in the United States identify as Black/African American (AA). Research and academic productivity are highly emphasized within the field and are crucial for career advancement at academic institutions. They also serve as important avenues for mentorship and recruitment of diverse trainees and medical students. This study aimed to summarize the academic accomplishments of AA neurosurgeons by assessing publication quantity, h-index, and federal grant funding.

METHODS

One hundred thirteen neurosurgery residency training programs accredited by the Accreditation Council for Graduate Medical Education in 2022 were included in this study. The American Society of Black Neurosurgeons registry was reviewed to analyze the academic metrics of self-identified Black or AA academic neurosurgeons. Data on the academic rank, leadership position, publication quantity, h-index, and race of neurosurgical faculty in the US were obtained from publicly available information and program websites.

RESULTS

Fifty-five AA and 1393 non-AA neurosurgeons were identified. Sixty percent of AA neurosurgeons were fewer than 10 years out from residency training, compared to 37.4% of non-AA neurosurgeons (p = 0.001). AA neurosurgeons had a median 32 (IQR 9, 85) publications compared to 52 (IQR 22, 122) for non-AA neurosurgeons (p = 0.019). AA neurosurgeons had a median h-index of 12 (IQR 5, 24) compared to 16 (IQR 9, 31) for non-AA colleagues (p = 0.02). Following stratification by academic rank, these trends did not persist. No statistically significant differences in the median amounts of awarded National Institutes of Health funding (p = 0.194) or level of professorship attained (p = 0.07) were observed between the two cohorts.

CONCLUSIONS

Racial disparities between AA and non-AA neurosurgeons exist in publication quantity and h-index overall but not when these groups are stratified by academic rank. Given that AA neurosurgeons comprise more junior faculty, it is expected that their academic accomplishments will increase as more enter academic practice and current neurosurgeons advance into more senior positions.

OBJECTIVE

Pediatric data regarding treatment via an auditory brainstem implant (ABI) remains sparse. The authors aimed to describe their experience at their institution and to delineate associated demographic data, audiometric outcomes, and surgical parameters.

METHODS

An IRB-approved, retrospective chart review was conducted among the authors’ pediatric patients who had undergone auditory brainstem implantation between 2012 and 2021. Demographic information including sex, age, race, coexisting syndrome(s), history of cochlear implant placement, average duration of implant use, and follow-up outcomes were collected. Surgical parameters collected included approach, intraoperative findings, number of electrodes activated, and complications.

RESULTS

A total of 19 pediatric patients had an ABI placed at the authors’ institution, with a mean age at surgery of 4.7 years (range 1.5–17.8 years). A total of 17 patients (89.5%) had bilateral cochlear nerve aplasia/dysplasia, 1 (5.3%) had unilateral cochlear nerve aplasia/dysplasia, and 1 (5.3%) had a hypoplastic cochlea with ossification. A total of 11 patients (57.9%) had a history of cochlear implants that were ineffective and required removal. The mean length of implant use was 5.31 years (0.25–10 years). Two patients (10.5%) experienced CSF-related complications requiring further surgical intervention. The most recent audiometric outcomes demonstrated that 15 patients (78.9%) showed improvement in their hearing ability: 5 with sound/speech awareness, 5 able to discriminate among speech and environmental sounds, and 5 able to understand common phrases/conversation without lip reading. Nine patients (47.4%) are in a school for the deaf and 7 (36.8%) are in a mainstream school with support.

CONCLUSIONS

The authors’ surgical experience with a multidisciplinary team demonstrates that the retrosigmoid approach for ABI placement in children with inner ear pathologies and severe sensorineural hearing loss is a safe and effective treatment modality. Audiometric outcome data showed that nearly 79% of these patients had an improvement in their environmental and speech awareness. Further multicenter collaborations are necessary to improve these outcomes and potentially standardize/enhance electrode placement.

OBJECTIVE

The objective of this study was to evaluate the efffectiveness of a titanium vertebral augmentation device (SpineJack system) in terms of back pain, radiological outcomes, and economic burden compared with nonsurgical management (NSM) (bracing) for the treatment of vertebral compression fractures. Complications were also evaluated for both treatment methods.

METHODS

A prospective multicenter randomized study was performed at 9 French sites. Patients (n = 100) with acute traumatic Magerl type A1 and A3.1 vertebral fractures were enrolled and randomized to treatment with the SpineJack system or NSM consisting of bracing and administration of pain medication. Participants were monitored at admission, during the procedure, and at 1, 12, and 24 months after treatment initiation. Primary outcomes included visual analog scale back pain score, and secondary outcomes included disability (Oswestry Disability Index [ODI] score), health-related quality of life (EQ-5D score), radiological measures (vertebral kyphosis angle [VKA] and regional traumatic angulation [RTA]), and economic outcomes (costs, procedures, hours of help, and time to return to work).

RESULTS

Ninety-five patients were included in the analysis, with 48 in the SpineJack group and 47 in the NSM group. Back pain improved significantly for all participants with no significant differences between groups. ODI and EQ-5D scores improved significantly between baseline and follow-up (1, 12, and 24 months) for all participants, with the SpineJack group showing a larger improvement than the NSM group between baseline and 1 month. VKA was significantly lower (p < 0.001) (i.e., better) in the SpineJack group than in the NSM group at 1, 12, and 24 months of follow-up. There was no significant change over time in RTA for the SpineJack group, but the NSM group showed a significant worsening in RTA over time. SpineJack treatment was associated with higher costs than NSM but involved a shorter hospital stay, fewer medical visits, and fewer hours of nursing care. Time to return to work was significantly shorter for the SpineJack group than for the NSM group. There were no significant differences in complications between the two treatments.

CONCLUSIONS

Overall, there was no statistical difference in the primary outcomes between the SpineJack treatment group and the NSM group. In terms of secondary outcomes, SpineJack treatment was associated with better radiological outcomes, shorter hospital stays, faster return to work, and fewer hours of nursing care.

Leather tanning can be done by soaking the skin in pits or rotating in tannery drums. Technical soaking of rotate movement and static soaking affects the skin microstructure matrix. This study aims to compare the quality of wet blue leather tanned by static soaking in a vessel and rotating in a tannery drum, particularly in terms of chrome uptake and thermal stability. The penetration time in the soaking experiment varied from 8, 16, 24, 32, 40, 48, and 56 hours. Meanwhile, the control was processed in a small-scale tannery drum with two hours of penetration time. Then, each sample was subjected to basification using HCOONa and NaHCO3. The results showed that all samples increased in weight and thickness after tanning. After penetration, wet blue leather tanned in a tannery drum performed better blue-green colour evenness compared with the soaked ones. Tannery drum leather also showed better chromium uptake, shrinkage temperature, and thermal stability. When the drum rotates, the pickled pelt gets mechanical action, such as being stretched, bent, and slammed, helping the collagen fibre open and the chromium penetrates deeper and faster. This study revealed that darker wet blue leather indicates higher thermal stability and chromium uptake.

Die Peripherie als Avantgarde
Authors: Hürtgen Stefanie
Published: March 2024

Der Beitrag unterstreicht die transnationale Perspektive im politökonomischen Denken von Maria Mies, Veronika Bennholdt-Thomsen und Claudia von Werlhof. Die sogenannten Bielefelderinnen konzipieren das Ökonomische zuvorderst als Praxis der Arbeit, des Tätigseins. Von hier aus argumentieren sie gegen herrschende Nord-Süd-Spaltungen und für die Dezentrierung des Nordens. In ihrer auf Subsistenz ausgerichteten Alternative allerdings produzieren sie selbst sozialräumliche Essenzialismen. Es geht ihnen um Ausstieg aus der Lohnarbeit, nicht um deren Überwindung. Wie auch weite Teile der Ökologiebewegung unterschreiten die Bielefelderinnen so die Auseinandersetzung um das gesellschaftliche Ganze der Arbeit.

Published: March 2024

In dem Beitrag wird vorgeschlagen, die Konzepte des Metabolismus der sozialen Reproduktion und des metabolischen Risses sowie eine materialistische Konzeption des arbeitenden Köpers in die soziale Reproduktionstheorie zu integrieren. Konkret werden die zeitlichen und räumlichen Konflikte der Arbeiter*innen in der brasilianischen und portugiesischen Flugindustrie um Arbeitsschutz und körperliche Unversehrtheit in den Blick genommen. Mit dieser empiriegeleiteten Analyse wird ein Begriff von Ausbeutung vorgeschlagen, der diese nicht auf die Werttheorie reduziert, aber auch nicht davon trennt.
soziale Reproduktion im Süden
Authors: Graf Jakob
Published: March 2024

Der Beitrag verbindet aktuelle Diskussionen um soziale Reproduktion mit einer Diskussion zu den »Überflüssigen«. Theorien der sozialen Reproduktion gehen tendenziell davon aus, dass kapitalistische Produktion und soziale Reproduktion über Lohnarbeit funktional vermittelt sind. Dagegen konstatieren Publikationen über die surplus society, dass große Teile der Weltbevölkerung nach wie vor kaum mittels kapitalistischer Lohnarbeit in den globalen Kapitalismus integriert sind. Diese Diagnose belege ich datenbasiert und vertrete die These, dass wir für ein Verständnis der Konflikte um soziale Reproduktion im Globalen Süden die Rolle des bedarfsökonomischen Sektors, öffentlicher Güter und sozialer Infrastrukturen in den Blick nehmen müssen.

Published: March 2024

Background: Dental anxiety among patients is a significant impediment leading to delayed or incomplete dental treatment. Understanding the determinants of dental anxiety is crucial, given the potential variations in causative factors across different regions due to cultural diversity and past dental experiences. In light of limited available data and cultural heterogeneity, this study aimed to explore the correlation between age, gender, educational level, socio-economic status, and residence with dental anxiety among patients seeking care at a teaching dental hospital.
Methods: A cross-sectional study involving 375 patients attending a private teaching hospital was conducted, with dental anxiety assessed using the Modified Dental Anxiety Scale. Exclusion criteria involved patients with known anxiety disorders or a history of intellectual disabilities.
Results: The findings demonstrated a statistically significant gender-based difference in dental anxiety (p-value: 0.00), with a majority of females exhibiting anxiety levels ranging from moderate to extreme. Additionally, a significant association was observed between socio-economic status and dental anxiety (p-value: 0.03), revealing lower levels of dental anxiety among individuals from lower socio-economic backgrounds compared to those from middle and upper socio-economic strata. However, no significant differences were identified in dental anxiety concerning age, educational level, and residence (urban/rural).
Conclusion: The study concludes that targeted anxiety reduction protocols should be prioritized for female patients and those belonging to the upper socio-economic status.

Authors: Hameed Aisha , Shafqat Syed Hassan , Hameed Sania , Hameed Safina , Anwar Javed , Shah Fahd
Published: March 2024

Background: Gliomas represent the most prevalent type of primary brain tumor and are associated with a significant mortality rate. The utilization of MR cerebral perfusion proves effective in distinguishing between low-grade and high-grade gliomas, surpassing the capabilities of routine MRI. This distinction allows for the timely initiation of surgical intervention. We aimed to document the diagnostic accuracy of MR cerebral perfusion against the gold standard of lab-based histopathology.
Methods: We conducted this cross-sectional validation study over a duration of six months in the outpatient radiology department of a major public sector hospital of Rawalpindi, Pakistan. All patients had MR cerebral perfusion Scan of brain in order to differentiate low grade and high grade glioma. Quantitative rCBV analysis was carried out adopting a threshold value of 3, above this value the lesion was considered at a high grade. The results were written on specially designed proforma.
Results: A total 230 patients were included in the study with mean age of 50.68+16.36 and there were 135 (58.7%) male and 95 (41.3%) were female. There were 122 (53.0%) patients presented with low grade glioma and 108 (47.0%) patients presented with high grade glioma. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of MR cerebral perfusion to differentiate between low grade and high grade gliomas was 85.71%, 70.97%, 88.89%, 64.71% and 81.74% respectively.
Conclusion: This study concludes that the MR perfusion reliably identifies higher-grade features in a tumor that otherwise may not appear on standard MRI scan.

Breastfeeding exclusively is beneficial not just to mothers but also to their children and society as a whole. Babies who are only given breast milk are protected against hazardous bacteria that may be found in formula and other baby meals, germs that can cause diarrhoea, other diseases, and even death. These harmful bacteria can be found in formula and other infant meals. Breast milk is the only food babies need. This research aimed to investigate exclusive breastfeeding practices among female healthcare professionals and mothers who received services at child welfare clinics in the Sissala East Municipality of Ghana. A facility-based quantitative descriptive cross-sectional design was used in this study. The study revealed that social support statistically influenced the practice of exclusive breastfeeding among the respondents. Lactating mothers whose close relatives supported them were 2.61 times more likely to practice exclusive breastfeeding than those not supported by their close relatives (COR: 2.61 (C.I: 1.26 – 5.39) P=0.010). Based on the results, conclusions were accordingly made.

The lives of people are at risk from security and safety risks with Intelligent Transportation Systems (ITS), particularly Autonomous Vehicles. In contrast to manual vehicles, the Security of an AV’s computer and communications components may be penetrated using sophisticated hacking methods, preventing us from employing AVs in our daily lives. The Internet of Vehicles, which connects manual automobiles to the Internet, is vulnerable to cyber-attacks such as lack of service, spoofing, sniffer, widespread denial of service and repeat attacks. This paper presents a unique intrusion detection system for ITS, using Enhanced Cuttle Fish Optimized Multiscale Convolution Neural Network (ECFO-MCNN), that uses vehicles to identify networks and infrastructure and detects careful network activity of in-vehicle networks. The primary goal of the suggested strategy is to identify forward events emanating through AVs’ central network gateways. Two benchmark datasets, namely the UNSWNB15 dataset for external network communications and the car hacking dataset for in-vehicle communications, are used to assess the proposed IDS. The evaluation’s findings showed that the performance of our suggested system is superior to that of traditional intrusion detection methods.
