Published: February 2025

AimsFracture-related infections (FRIs) are a major concern for patients and healthcare systems, yet their impact on mental health has been largely overlooked. This study aimed to assess the longitudinal impact of FRI on patients’ quality of life.MethodsA prospective study was conducted at a level 1 trauma centre between January 2020 and December 2022. In total, 56 patients participated, with quality of life assessed at five timepoints: one week preoperatively, and one, three, six, and 12 months postoperatively. Statistical analysis was performed using repeated measures analysis of variance (ANOVA) with adjusted post-hoc analysis.ResultsThe preoperative Physical Component Summary score on the 36-Item Short-Form Health Survey questionnaire (SF-36) was 26.71, increasing to 30.40 at one month, remaining stable at three months. A modest increase was observed at six months (32.45, p = 0.003), but it decreased to 29.72 at 12 months. The preoperative Mental Component Summary score (SF-36) was 46.48, decreasing to 39.89 at one month (p = 0.027) and to 36.03 at three months (p ≤ 0.001). However, it improved at six (42.74) and 12 months (44.05). Positive changes were seen in EuroQol five-dimension questionnaire (EQ-5D) subdimensions, such as mobility, self-care, usual activities, and pain/discomfort, while anxiety/depression scores decreased over time. The EQ-5D visual analogue scale (VAS) score increased to 62.79 at six months (p ≤ 0.001) and decreased to 58.2 at 12 months (p = 0.011).ConclusionFRIs substantially affect mental health and quality of life, particularly during the initial three months of treatment. This study emphasizes the importance of addressing psychological aspects early in FRI management, advocating for holistic care encompassing both physical and psychological aspects of treatment.Cite this article: Bone Joint Res 2025;14(2):136–142.
The effectiveness of Evodia rutaecarpa hot compress on the recovery of gastrointestinal function after laparoscopic surgery for colorectal cancer: A propensity score-matched retrospective cohort study
Authors: Huang Miaoxin , Li Junmiao , Huang Wei , Zhou Yuling , Cai Lei , Liu Ming 
Published: February 2025

Background
Although the use of hot compresses with the herbal medicine Evodia rutaecarpa (ER) as a complementary and alternative therapy to promote recovery of postoperative gastrointestinal function is gradually increasing in clinical practice, there is still a lack of relevant empirical studies. Particularly, the role of ER hot compress therapy on gastrointestinal recovery post-laparoscopic surgery for colorectal cancer has not been well investigated. The purpose of this study is to evaluate the efficacy and applicability of ER hot compress therapy for the recovery of postoperative gastrointestinal function.

Methods
This is a retrospective cohort study. Patients were divided into two cohorts, the ER group and the non-ER group. Propensity score matching(PSM) was introduced to limit confounding, and independent samples t-tests, non-parametric tests, or Chi-squared tests were used to compare these two cohorts.

Results
A total of 454 patients were included, with 267 (59%) receiving ER hot compress therapy and 187 (41%) not. After 1:1 PSM, 320 patients were analyzed (160 in each group). Compared to the ER group, patients in the non-ER group had shorter times to return to a semi-liquid diet (p = 0.030) and hospital stay (p<0.001), as well as lower hospital costs (p<0.001). Subgroup analyses revealed no statistically significant differences in the length of hospital stay, hospital costs, postoperative time to return to full-liquid diet, or time to return to semi-liquid diet among stage I and II tumor patients. However, except for hospital costs, the means and standard deviations of the other indicators were generally lower in the ER group. Complication incidence showed no significant difference between the two cohorts before and after PSM.

Conclusions
The use of ER hot packs after laparoscopic surgery in patients with colorectal cancer has a non-significant effect on the recovery of the gastrointestinal function and, given the results of the study, it is likely that patients with early-stage tumors may benefit more. Therefore, healthcare providers need to consider the individualization, practicality, and economics of treatment options.
Associations between cognitive activities and all-cause mortality among older adults with cognitive impairment: A prospective cohort study
Authors: Duan Linjia , Zhao Liming , Wang Ziqiong , Liu Lu , Song Ningying , He Sen 
Published: February 2025

Background
Evidence on the association between cognitive activities and mortality among older adults with cognitive impairment is limited. Therefore, the study aimed to assess the association and examine whether baseline cognitive function mediates the association.

Methods
A total of 10477 older participants with cognitive impairment (median age: 95.0 [IQR: 88.0–100.0], males: 27.9%, Mini-Mental State Examination score ≤24 points) from the Chinese Longitudinal Healthy Longevity Survey conducted between 1998 and 2014 were included, with follow-up until 2018. Exposures were three prevalent cognitive activities among older adults in China: reading books/newspapers, playing cards/mah-jong, and watching TV or listening to radio, and the outcome was all-cause mortality within a 10-year follow-up period. We evaluated the association between these activities and mortality using Cox regression models and also conducted a mediation analysis to examine the role of baseline cognitive function in this association.

Results
During a follow-up period of totaling 33632.1 person-years, there were 8763 recorded deaths (83.6%). For each cognitive activity, the risk of mortality decreased with an increased frequency of engagement in these activities. Moreover, the risk of mortality significantly decreased with a greater number of cognitive activities. With zero activities as reference, adjusted hazard ratios were 0.83 (95% CI: 0.79–0.87) for one activity, 0.76 (95% CI: 0.69–0.83) for two activities, and 0.67 (95% CI: 0.53–0.86) for three activities, respectively. Stratified and sensitivity analyses confirmed the robustness of these findings. Additionally, baseline cognitive function partially mediated the association between cognitive activities and mortality; compared to zero activities, the mediated proportions were 15.2% (95% CI: 10.9%–22.4%) for one activity, 13.4% (95% CI: 8.9%–21.3%) for two activities, and 9.3% (95% CI: 4.2%–23.4%) for three activities, respectively.

Conclusions
Among older adults with cognitive impairment in China, the risk of all-cause mortality significantly decreased as both the frequency and number of cognitive activities increased. Baseline cognitive function only mediated a small proportion of the benefits of cognitive activities in longevity.

Nutrien merupakan material kimia yang penting bagi kelangsungan hidup organisme perairan. Keberadaannya di kolom perairan dapat dijadikan sebagai penentu apakah perairan berada dalam kondisi subur atau tidak. Sumber nutrien di perairan dapat berasal dari aktivitas manusia seperti pemukiman dan pertanian yang terdapat di darat dan masuk ke kawasan muara melalui aliran sungai. Meskipun demikian, masuknya nutrien dalam jumlah besar dapat menurunkan kualitas perairan karena dapat memicu terjadinya eutrofikasi. Penelitian ini bertujuan untuk mengetahui kondisi nutrien di air dan sedimen serta TSS dan karakteristik sedimen di sekitar Perairan Pulau Payung. Pengambilan sampel dilaksanakan bulan September 2022 pada 5 stasiun penelitian, analisis nitrat dan fosfat pada sampel air mengacu pada metode brusin sulfat SNI 06-2480-1991 dan SNI 6989.31-2015. Analisis nitrat pada sedimen menggunakan metode bruan dan analisis fosfat merujuk pada metode SNI 19-2483-1991. Analisis tekstur sedimen menggunakan metode ayak kering dan analisa TSS dengan metode penyaringan. Hasil penelitian menunjukkan konsentrasi nitrat di kolom perairan Pulau Payung berkisar 1,7-2,8 mg/l (telah melebihi baku mutu, 0,008 mg/L berdasarkan Kepmen LH (2004) dan 0,07 mg/L berdasarkan US-EPA (1973), sementara fosfat berkisar 0,25-0,48 mg/l (tidak melebihi baku mutu 0,2 – 1,0 mg/L berdasarkan Kepmen LH PP RI No.22 Tahun 2021). Konsentrasi nitrat sedimen Pulau Payung berkisar 24,69-40,41 mg/kg (tergolong perairan dengan kandungan nitrat tinggi) dan fosfat berkisar 1,15-1,54 mg/kg (tergolong perairan dengan kandungan fosfat sangat rendah). Sedimen Pulau Payung sebagian besar didominasi substrat lempung dan sebagian kecil lempung berpasir. Adapun nilai TSS yang ditemukan berkisar antara 115,22 – 212,97 mg/l.

AbstractPeripheral blood mononuclear cells (PBMCs) represent a heterogeneous mix of cells with paracrine functions that may be altered following prolonged exercise. We determined the effect of ultramarathon running on PBMC paracrine function and PBMC subtype number. Recreational athletes participated in a 50 km ultramarathon. Blood was sampled from N = 7 at baseline, 10 km, 50 km, and 24 h post‐race. PBMCs were isolated and cultured, and conditioned media was used for a HUVEC‐based proliferation assay. CD31+, CD3+, and CD31+/CD3+ PBMCs were quantified at each time point. Proliferation increased from baseline to 50 km (p = 0.004) and was reduced from 50 km to 24 h post (p = 0.008). There was an increase in CD31+ PBMCs after 50 km (p = 0.014), returning to baseline at 24 h post‐race (p = 0.246). CD3+ PBMC and CD31+/CD3+ PBMC numbers were reduced after 50 km (p = 0.001 and p = 0.002, respectively), returning to baseline levels 24 h post‐race (p = 0.190 and p = 0.315, respectively). PBMC paracrine activity following a 50 km enhances endothelial cell proliferation. Alterations in PBMC subtypes after 50 km suggest a protective role of PBMCs in response to prolonged stresses of ultramarathon running.

A cross-sectional study on risk factors of premenstrual syndrome among college-going students in Pune
Authors: Lamkhade Shriya Vitthal , Gokhale Devaki , Thakur Harshada Ketan 
Published: February 2025

Abstract

Objectives
Premenstrual Syndrome (PMS) is a combination of emotional and physical symptoms occurring the week before menstruation and lasts 2–3 days during menstruation. This study aims to examine the dietary intake and lifestyle triggers among students with and without PMS from Pune, India.

Methods
We conducted an interview-based, cross-sectional study among 360 college-going students aged 18 to 24 in Pune. The questionnaire recorded socio-demographic details, anthropometry, physical activity, substance abuse, and dietary habits. A Food Frequency Questionnaire assessed dietary patterns, while the MDQ (Menstrual Distress Questionnaire) diagnosed PMS. PMS severity was measured using the Premenstrual Screening Tool (PSST). Risk determinants for PMS were analyzed, with significance set at p<0.05.

Results
The prevalence of PMS among 18-24-year-old college students was 51.4 %. There is no association observed between participants’ demographic and anthropometric characteristics with PMS. It was observed that participants who frequently consumed cakes, pastries, and pizza and those who consumed contraceptive pills, slept 5–6 h on weekdays were at higher risk of experiencing PMS symptoms.

Conclusions
This study suggests that frequent consumption of cakes, pastries, and pizza is a potential risk factor for increasing the incidence of PMS among college students. The severity of symptoms was notably higher among those who used contraceptive pills and had shorter sleep durations.

A comprehensive review of deep learning and machine learning techniques for early-stage skin cancer detection: Challenges and research gaps
Authors: Alzamili Ali. H. , Ruhaiyem Nur Intan Raihana 
Published: February 2025

Abstract
Skin cancer especially when detected early can be easily treated, but its diagnosis is complicated by the minimal difference in the appearance of early lesions and the requirement of a precise diagnostic technique. The goal of this intensive literature review is to evaluate the progressive enhancements of deep learning (DL) and machine learning (ML) methods for transferring early-stage skin cancer identification in terms of accuracy and in terms of usability for real-world clinical applications. By using support vector machines, convolutional neural networks, and ensemble methods, we assess the performance of such algorithms in the classification and segmentation of skin lesions within various datasets. The challenges outlined in the review include the following: first, sparsity of data, second, variation in the looks in lesions, and third, imbalance of data within classes. Furthermore, issues that are still open to investigation are also presented, including the restricted number of algorithms for which the developed DL/ML models can be interpretable and the variability of the results assessment criteria used in different investigations. We then propose possible approaches to these issues such as data augments, multimodal learning, and the inclusion of explainable artificial intelligence approaches. The strengths of the present study consist of a comprehensive review of the limitations of contemporary methodologies and recommendations for future research on DL/ML-based systems for the early diagnosis of skin cancer. This research aims to highlight the best techniques and identify areas for future improvement. The study highlighted the key challenges of evaluating skin lesion segmentation and classification techniques, for instance, small sample size dataset, or selective and random image acquisition or even racial prejudice.

Authors: Mkhize Nomthandazo , Rajasekhar Pullabhotla Viswanadha Srirama 
Published: February 2025

Abstract
This study investigated the catalytic potential of metal-loaded gamma alumina catalysts in the ozonation of 1,2-dichlorobenzene (DCB) under ambient reaction conditions. Different metal (Fe, Ni, and V) loaded gamma alumina catalysts were synthesized via wet impregnation technique and characterized using ICP-OES, FT-IR, BET, XRD, TEM, and SEM techniques. To identify the reaction products, Fourier transform infrared (FT-IR) spectroscopy and gas chromatography-mass spectrometry (GC-MS) techniques. The ozonation of 1,2-dichlorobenzene was studied within a glass reactor, where each substrate was exposed to ozone for varying time durations between 3 and 24 h. The catalytic performance of a range of metal-loaded γ-Al2O3 catalysts was assessed by examining their conversion and selectivity capabilities. During the oxidative degradation of 1,2-dichlorobenzene, 3,4-dichloro-2,5-furandione (DHF) and mucochloric acid (MCA) were identified as the ozonation products. Among the studied catalysts, 2.5 % Ni/γ-Al2O3 exhibited outstanding catalytic activity towards the conversion of 1,2-dichlorobenzene yielding a significant 65 % conversion of 1,2-dichlorobenzene after 24 h of ozonation.
Flotation equipment automation and intelligent froth feature extraction in flotation process: a review
Authors: Dong Haipei , Wang Fuli , He Dakuo , Liu Yan 
Published: February 2025

Abstract
Flotation is the most widely used technology for mineral separation and purification. The flotation production process has complex mechanism characteristics and is influenced by multiple variables that are coupled with each other, which has always been a difficulty in controlling the beneficiation process. The flotation system of mineral processing plants mostly relies on manual control, which is influenced by subjective factors such as worker experience, technical level, and sense of responsibility, making it difficult to optimize control parameters and maximize production efficiency. This paper systematically summarized the automation systems of flotation equipment such as automatic dosing device, automatic liquid level detection device, automatic feed concentration adjustment device, and automatic feed flow adjustment device. The accurate extraction methods of physical and dynamic characteristics such as color, texture, size, and moving speed of flotation froth were reviewed. The traditional data-driven model and image feature-based prediction methods for prediction of the grade, recovery rate, ash content in the concentrate, and tailings were combed. On this basis, a technical route for achieving intelligent flotation process was proposed with the aim of providing theoretical and practical references through the collaborative operation of flotation devices, detection sensors, and machine learning algorithms.

Intellectual Component of Human Language Model in the Russian and Baltic Languages (based on Material of Phraseological Units of the Russian, Latvian and Lithuanian Languages)
Authors: Stoikova Tatyana 
Published: February 2025

The article considers the intellectual component of the Russian and Baltic human language model (HLM) based on the material of phraseologisms. The intellectual component is characterized by somatic phraseological units (PhU) with key components correlated in Russian and Baltic languages: Rus. голова, мозг (мозги), ум, разум, рассудок / Latv. galva, smadzenes, prāts, saprāts / Lithuan. galva, smegenys, protas, omuo. In the semantics of the analyzed PhU, the following aspects of human intellectual activity are updated: normal / abnormal intellectual state; judiciousness, common sense / imprudence; good / poor mental capacity; a “container” of thoughts and quantitative indicators of mind and knowledge; memory abilities, normal thought activity / mental disorders. A comparative analysis of the semantics of Russian and Baltic PhU revealed common typological features of the compared HLM. Interlanguage Russian and Baltic correspondences in most cases are full equivalents, that is, identical in structure, composition of components and figurative bases, less often they are partial, that is, such in which there is a variation in components and grammatical structure. The identity of figurative foundations is a demonstration of the commonality of cultural connotations which, in turn, testifies to the commonality of many cultural attitudes of Russians and Balts. Apparently, interlanguage Russian, Latvian and Lithuanian equivalents go back to identical prototypes that developed into corresponding PhU under the combined action of universal (for all three ethnic groups) linguistic and extralinguistic factors, and this confirms the hypothesis of interlanguage phraseological parallelism, especially in the case of somatic phraseologisms.
