Published: February 2025

BackgroundHallux Valgus (HV) is a common forefoot deformity that can cause pain and difficulty with walking. There are a range of surgical techniques to treat HV deformity, but there is a risk of recurrence. This paper reviews the clinical assessment and management of recurrent HV as well as a detailed description of how percutaneous surgical techniques can be used to treat recurrent HV. This paper identifies technical challenges of percutaneous HV surgery for recurrent HV deformity as well as strategies to address and mitigate these.MethodThis was a multicenter retrospective review of adult patients who had recurrent hallux valgus deformity (defined as hallux valgus angle&gt;15° and having previously undergone primary surgical intervention for HV deformity correction) who were treated with a percutaneous metatarsal extra-capsular transverse osteotomy (META) technique, with at least one year of follow-up data. Demographic information, hallux valgus angle, intermetatarsal angle, Manchester-Oxford Foot Questionnaire (MOXFQ), visual analog scale (VAS), and EQ-5D-5L scores were collected.ResultsWe retrospectively evaluated 34 feet from 32 patients with a mean age of 63.1±9.2 (range 41–82) who underwent revision hallux valgus surgery using a percutaneous technique. The mean follow up was 3.6±2.3 (range 0.5–8.7 years. The breakdown of index HV surgeries was: 17 Chevron, 9 Scarf/Akin, 6 medial bunionectomy, 1 Lapidus, 1 proximal rotation osteotomy. There was a statistically significant improvement in both clinical foot function and radiographic deformity after surgery. The mean HV angle decreased from 32.9±8.6° to 13.4±7.3°, and the intermetatarsal angle decreased from 12.7±3.8° degrees to 3.8±3.1°(p<0.05). The mean MOXFQ Index score significantly improved from 49.4±23.1 to 14.6±19.4 (p<0.05).ConclusionThis paper suggests that percutaneous surgical techniques using a transverse osteotomy and screw fixation can successfully treat a wide range of recurrent HV deformity severities with significant improvement in clinical and radiographic outcomes.
IS THE DISTAL METATARSAL METAPHYSEAL ANGLE REALLY JUST METATARSAL PRONATION? A WEIGHTBEARING CT ANALYSIS

Published: February 2025

AimsThe distal metatarsal metaphyseal articular angle (DMMA) is a measurement used in the surgical decision making of hallux valgus correction. However, it is difficult to measure on plain radiographs, is subject to projection bias, and its role in pathology is unclear. With the advent of weight-bearing CT (WBCT), our understanding of hallux valgus as a multiplanar deformity has evolved. The aim of this study was to investigate whether there is a relationship between the DMAA and pronation of the first metatarsal head in patients with hallux valgus.MethodsThis was a single-centre, retrospective analysis of 50 patients with hallux valgus deformity who had WBCTs obtained as part of routine pre-operative work-up. Patients with metatarsophalangeal joint arthritis, hindfoot deformity and previous surgery were excluded. From the WBCT images digital radiographs were created and the DMMA measured. Measurements were taken by 2 authors, each repeated twice and the average of all four measurements used in analysis. We also measured intermetatarsal angle (IMA), hallux valgus angle (HVA) and metatarsal pronation angle (MPA).ResultsThere were 41 females and 9 males, mean age 52.4±15.8 years. IMA was 14.5±3.3 degrees, HVA was 29.3±8.4 degrees, MPA was 11.7±6.3 degrees, and DMMA was 15.5±5.3 degrees. Intraclass correlation coefficient (ICC) for intra-observer reliability was 0.829 for assessor 1 and 0.910 for assessor 2. ICC for inter-observer reliability was 0.727. Pearsons correlation revealed no link between IMA and DMAA, nor HVA and DMMA. However, there was a significant (albeit small) correlation between MPA and DMMA (r=0.337, p=0.017).ConclusionThere was reasonable reliability in measuring DMMA between authors on WBCT. Despite this, DMMA appeared to increase with increasing metatarsal pronation. The DMMA may therefore be (in part) projection artefact secondary to metatarsal pronation and surgeons should be aware of this during surgical planning.

A study was conducted to determine the protein degradation characteristics of 27 tropical feedstuffs for dairy rations. Twenty-two tropical feedstuffs were grouped into A1 (local low fiber and low protein sources: corn, rice bran, cassava, cassava waste, wheat, pollard), A2 (local low fiber and low protein sources: palm kernel meal, tofu waste, tempe waste), and A3 (local high fiber sources: acacia, alfalfa, narra, gliricidia, indigofera, calliandra, bauhinia, leucaena, albizia, agati, piper, moringa, jack leaves), and compared to A4 (imported low fiber high protein sources: soybean, roasted soybean, DDGS, CGM, CGF) using the in sacco method. The study revealed that A1, A2, and A3 had lower protein content but higher crude fiber than A4. Protein solubility (a) was higher in A1 and A2, while the potentially degraded fraction (b) was higher in A2 and A3. A1 and A2 had higher RDP fractions than A3 and A4. High RDP feedstuffs include pollard, wheat, soybean, CGF, tempe waste, alfalfa, gliricidia, indigofera, agati, and moringa. In contrast, high RUP feedstuffs include corn, palm kernel meal, narra, calliandra, leucaena, albizia, tamarind, piper, jack leaves, roasted soybean, soybean meal, and CGM. Tropical feedstuffs exhibit diverse protein degradation characteristics, making them valuable for strategic ration formulation in dairy cattle.

Structural characterization of the Zalm district, West Saudi Arabia, using aeromagnetic data: An approach for gold mineral exploration
Authors: Alzahrani Hassan , Ibrahim Elkhedr 
Published: February 2025

Abstract
The Zalm district in western Saudi Arabia has drawn significant attention from those interested in exploring for gold mineralization. In the present study, the structural framework and major structural trends that most likely control the distribution of the gold mineral deposits in the Zalm district are interpreted using aeromagnetic data. For this purpose, the aeromagnetic data were subjected to enhancement filters to make the structural interpretation of the data easier. In this respect, the data were reduced to the north magnetic pole and processed through two enhancement filters: the analytical signal (AS) and the first vertical derivative (1VD). Lineament analysis of aeromagnetic maps suggests that three major fault sets dissected the Zalm district trending in the northwest (NW), northeast (NE), and north-south (NS) directions. These faults likely affected the mineralization occurrences in the Zalm district and could serve as important structural conduits for hydrothermal fluid channeling. Based on the current results, four localities were identified as promising for additional mineral resource investigation. These localities are delimited and dissected by the NW, NE, and NS faulting and are intruded by a series of felsic and mafic–ultramafic intrusions. It is likely that, in similar to Bi'r Tawilah where the location is structurally controlled by NW and NS faulting, the interpreted felsic and mafic served as sources of mineralizing fluids which remobilized the ore in the district by channeling through the faults. Three of the suggested localities, one lying in close proximity to Zalm city and two along the Rada and Nabitah fault zones, are characterized by high magnetic anomalies, indicating the presence of ultramafic and volcanic rocks that most likely host mineralization. The fourth locality situated in the central part of the district is marked by an elongated N–S low magnetic anomaly, interpreted as felsic diorite and granite rocks delimited by N–S faulting. To accurately detect mineral resources in the selected zones, additional comprehensive and in-depth geological and geophysical research are recommended.
Surface integrity studies in microhole drilling of Titanium Beta-C alloy using microEDM
Authors: Narayan Yeole Shivraj , Prakash Kode Jaya , Reddy Maddika Harinatha , Sridhar Babu B. 
Published: February 2025

Abstract
Micro electro-discharge machining, commonly known as MicroEDM, is used in the manufacturing industry for micromachining due to its benefits over conventional manufacturing. Titanium and its alloys find their application in various sectors. Titanium Beta-C alloy is one such alloy, especially employed in the oilfield and underwater sectors. Various applications in these fields need to have microholes embedded in them. Moreover, these parts need to possess high strength and be corrosion-resistant. Hence, the surface integrity of this alloy is critical. The intent behind this investigation is to evaluate the surface integrity characteristics of Titanium Beta-C alloy by performing microhole drilling using microEDM process parameters. In this study, surface integrity characteristics like surface topography and morphology are investigated by drilling microholes using brass electrodes of 300 µm in L9 orthogonal array experiments. Pulse on time, pulse off time, voltage, and current as pulse parameters are employed. Responses measured are surface roughness (R
a), SEM microstructure, and energy dispersive X-ray analysis. This investigation shows the formation of irregular shapes of the craters on the surface of microholes drilled in Titanium Beta-C alloy. Additionally, these surfaces exhibit shallow crater depths and do not show the presence of cracks.
The (Un)intended Consequences of Legal Transplants: A Comparative Study of Standing in Collective Litigation in Five Jurisdictions
Authors: Kalajdzic Jasminka , Halfmeier Axel , Murphy Bernard , Tzankova Ianika , Gómez Manuel A. 
Published: February 2025

Abstract
Deborah R. Hensler has long championed the comparative study of civil procedure in a way that considers the interplay between legal rules, redress mechanisms, legal institutions and the societies where they operate. More importantly, this approach has also revealed the intended and unintended consequences of legal transplantation, and illuminated the difference between the law in the books and the law in action. As Professor Hensler recently and succinctly wrote, “procedures that seem on the surface to be the same or very similar may in practice operate differently as they intersect with other aspects of the litigation regime – rules, cultural expectations, political contexts – in which they are inserted.” In a multi-year book project she led almost a decade ago, Hensler and her colleagues identified the cultural, economic and political forces that impact how a single procedural device – representative litigation – operates in any given jurisdiction. The studies that comprised the project were grounded in empirical data obtained through several research strategies, specially the case study method. National jurisdictions or specific cases within those jurisdictions were used as units of analysis, and as a basis for a broader cross-country comparison that helped identify points of convergence and also key differences.
Italia: Open to meraviglia at the intersection of art, gender and tourism discourses
Authors: Francesconi Sabrina 
Published: February 2025

Abstract
This article explores the status and role of Venus within the Italia: Open to meraviglia campaign, with a focus on a dataset of visual texts extracted from the venereitalia23 Instagram profile over the initial year of its publication. The adopted integrated framework encompasses the grammar of visual design by Kress and van Leeuwen, the interdiscursivity model developed by Bhatia and a scale for measuring sexism in tourism representations by Pritchard. The questions that guide the research are the following: How is venereitalia23 visually represented across the Instagram profile? How do art and gender discourses intersect with one another within the campaign? Italia: Open to meraviglia employs an originally aesthetic icon by Sandro Botticelli. The creative solution may be seen as paying a tribute to Italian heritage. Similarly, the choice, coding and use of Venus as the ambassador and influencer may be read as challenging stereotyped gender representation in tourism discourse. However, the results show that the graphic configuration venereitalia23 achieves in the virtual dimension (through gestures, actions, clothing, gaze, size of frame, information value) makes it resemble a doll-influencer. Ultimately, the campaign fails in both celebrating the artistic heritage and emancipating the female role, as both are exploited and objectified.

Published: February 2025

Abstract
A coupled Hidden Markov Model (cHMM) is a hidden Markov model whose hidden Markov chain is bi-dimensional. In this paper, we focus to solve the likelihood and the decoding problems of a cHMM whose state space is composed of a continuous part and a discrete part. We adapt Forward, Backward and Viterbi algorithms to be able to study such cHMMs problems. Basic numerical examples are considered to show the well functioning of the elaborated algorithms for our proposal.
Monetary Policy and Growth at Risk: The Role of Financial Conditions
Authors: Zhang Licheng 
Published: February 2025

Abstract
Previous studies mainly examine the monetary policy transmission to average growth outcomes, this paper instead studies the effects of monetary policy on the tail outcomes of GDP growth – Growth at Risk (GaR). We first use quantile regression to estimate the conditional distribution of GDP growth, and then estimate the impulse responses with smooth local projections. Our results show that GaR deteriorates in response to contractionary monetary policy shocks, suggesting an increase in macroeconomic tail risk. We investigate the role of financial conditions in the transmission of monetary policy to GaR. We find that contractionary monetary policy shocks lead to tighter financial conditions, and tighter financial conditions have significant negative effects on GaR. Moreover, we show that tighter financial conditions increase future recession risk in both the short and medium term.

BACKGROUND
In health care conversations, clinicians continue to use medical jargon despite assuming they are communicating clearly, causing confusion for patients. Prior studies have evaluated adults’ perception of medical jargon, but few studies have evaluated how teenagers perceive it.

OBJECTIVES
To characterize teenagers’ comprehension of common phrases used in medical settings via a cross-sectional, survey-based investigation.

METHODS
A total of 71 teenagers aged between 13 and 17 years were recruited at the 2023 Minnesota State Fair to participate in an anonymous survey assessing their understanding of common phrases a doctor might say or write. Responses were coded as correct, partially correct, or incorrect by 2 independent researchers, with a third reconciling discrepancies. Secondary analyses evaluated the associations between participant demographics and understanding.

RESULTS
Teenagers demonstrated a poor understanding of many phrases evaluated. While 97% knew that “negative cancer screening” results meant they did not have cancer, fewer (69%) understood that “the tumor is progressing” was unwelcome news. More teenagers understood “your blood test shows me you do not have an infection in your blood” (89%) vs “your blood culture was negative” (52%). Only 10% understood that “bugs in the urine” conveyed a urinary tract infection, with 37% expressing a literal interpretation. None knew what was meant by an “occult infection” nor by “febrile,” with 13% believing that it was related to fertility or sexual activity.

CONCLUSIONS
Teenagers frequently misunderstood common phrases used within a medical context, with interpretations, at times, representing the opposite of what a health care provider intended.
How do the divestment trends correlate with the green transformation of oil and gas companies?
Authors: Bartalos Éva , Sárvári Balázs 
Published: February 2025

AbstractThe green transformation of oil and gas companies is necessary to tackle climate change. Most of the green transformation related activities have been launched since the Paris Agreement was ratified. The main purpose of this article is to highlight how oil and gas companies handle the pressure of shifting their fossil fuel-based portfolio by analyzing their divestment trends. In our sample, six large, medium, and small oil and gas companies – Shell Royal Dutch (UK-based), British Petroleum (UK-based), OMV (Austrian), PKN Orlen (Polish), Neste (Finnish) and Orsted (Danish) – are assessed regarding the maturity of their green transition via the lens of their divestment figures between 2017 and 2022. The biggest leaps in green transition have been taken by small companies with the support of their governments. The majority of the divested portfolios were purchased by companies outside of the European Union (EU). This research offers a significant contribution to the literature on green energy transition, focusing on the divestments trends of oil and gas companies.
Support, supervision, and job satisfaction: Promising directions for preventing burnout in South African community service occupational therapists
Authors: Struwig Nadia , Van Stormbroek Kirsty 
Published: February 2025

Background:
Community service occupational therapists may be especially vulnerable to experiencing burnout. This study sought to determine the levels of burnout experienced by this population and to investigate the relationship between reported burnout and various contextual, personal, and demographic factors.
Methods:
A quantitative, descriptive, cross-sectional survey design was used. The online questionnaire included contextual information of the participants and the Maslach Burnout Inventory. Data were analysed using Statistica 13.5. The effect of contextual, personal and demographic variables on burnout was tested using Kruskal-Wallis tests.
Results:
All community service occupational therapists were invited to participate in the study. A response rate of 31.92% was achieved (n=75). High levels of emotional exhaustion were reported by 55% (n=41) of participants. ‘Strong’ and ‘adequate’ support systems were associated to a greater sense of personal accomplishment (p=0.02) and ‘minimal’ social support was associated to increased emotional exhaustion (p=0.01). Dissatisfaction with supervision was associated to increased emotional exhaustion (p=0.017). Job satisfaction was associated to a greater sense of personal accomplishment (p=0.0002). Job dissatisfaction was associated to depersonalisation (p=0.047) and emotional exhaustion (p=0.006).
Conclusion:
Support systems, supervision and job satisfaction showed significant association to burnout. Interventions to address these factors, and research that further investigates the impact of contextual factors on burnout is recommended. This is imperative if South African occupational therapy is to take seriously its responsibility to the therapists responsible for taking services to populations with the greatest health needs.
Implications for practice
Opportunities for occupational therapists to develop professional resilience to prevent burnout should be offered across the lifelong learning continuum.
• Strengthening supervision capacity and implementing mentoring and supervision strategies that provide mutual reward for both parties are needed.
• The responsibility for promoting the vitality and job satisfaction of COSTs should be taken seriously by the Department of Health as CSOTs continue the vital work of taking rehabilitation to South Africa’s populations with the greatest health needs.

Published: February 2025

Aim: Bone-metastatic prostate cancer (PCa) is a debilitating disease with few therapeutic options once androgen independence and chemotherapeutic resistance develop. Advanced PCa has metabolic vulnerabilities involving glycolysis, which is mediated by class I glucose transporters (GLUTs1-4). We previously patented DRB18, a small molecule pan-class I GLUT inhibitor that successfully inhibited the growth of a human lung cancer xenograft in mice. The purpose of this study was to determine the sensitivity of advanced PCa to GLUT antagonism using DRB18.
Methods: Bioinformatics was performed on human and canine PCa datasets to determine the clinical expression of class I GLUTs. Glucose uptake and cell viability in response to DRB18 were measured in vitro . Tibias of athymic mice were inoculated with Ace-1 canine PCa cells and treated with DRB18. The combination of DRB18 with cytotoxic docetaxel was assessed in vitro .
Results: Expression of important class I GLUTs and glycolysis genes increased during PCa progression in men and dogs. DRB18 reduced cancer cell glucose uptake and cell viability in a dose-dependent manner. Half-maximal inhibitory concentrations (IC50) ranged from 20-30 µM. DRB18 did not prevent intratibial PCa growth in vivo and had toxic effects at higher concentrations. DRB18 and docetaxel combination therapy and gene expression data from publicly available human PCa samples indicated docetaxel treatment does not stimulate glucose-related metabolic pathways.
Conclusion: GLUT1 inhibition alone or with combination therapy may not be appropriate for bone-metastasis inhibition. The results contribute to evidence that suggests bone metastatic PCa is not glucose dependent.
