The biomechanical impact of static or dynamic stretching on balancing ability: A systematic review and meta-analysis
Authors: Guo Weishuai , Kim Youngsuk , Wu Chaojie , Kim Sukwon
Published: January 2025

This study aims to evaluate the biomechanical effects of static stretching (SS) and dynamic stretching (DS) on balance abilities through a systematic review and meta-analysis. Following the PRISMA and PERSIST guidelines, a comprehensive search was conducted in July 2024 across PubMed, Web of Science, Cochrane, Embase, and EBSCO databases for randomized controlled trials assessing the influence of SS and DS on balance abilities in healthy adult populations. A total of twelve studies involving 308 participants were included in this analysis. The primary meta-analysis revealed that static stretching (SS) significantly impaired static balance abilities compared to dynamic stretching (DS), with an effect size of −0.05. Additionally, regression analysis identified stretching duration as a significant source of heterogeneity in static balance, highlighting considerable biomechanical variation. No significant changes were observed for center of pressure (COP) or dynamic balance. Bubble charts illustrated that as stretching duration increased, the effect size on static balance decreased, with multiple effect sizes clustering around the 20 s–200 s duration. Overall, dynamic stretching (DS) is superior to static stretching (SS) in enhancing balance abilities among healthy populations, particularly regarding static balance. Regression analysis indicated that stretching duration is a critical biomechanical factor influencing static balance, with optimal effects observed within the range of 20s to 200s.

Published: January 2025

Biomechanical efficiency of baseball pitch is considered to be a better indicator for evaluating pitching skills. Since there is a relationship between elbow varus and elbow mechanics during the arm cocking phase, we attempted to include this variable in the multiple regression analysis to improve the understanding of the biomechanical efficiency of baseball pitching. The fastest pitching of 68 college baseball pitchers was used for analysis. The regression results showed that maximum elbow flexion angle (β: −2.615, p: 0.003), shoulder external rotation angle at the moment of maximum external rotation (MER) (β: 2.881, p: 0.004), maximum trunk rotation velocity (β: −0.333, p: 0.001), trunk rotation angle at the moment of stride foot contact (SFC) (β: −2.031, p:0.006), time between maximum pelvic rotation velocity and maximum trunk rotation velocity (β: 1.238, p: 0.023), and shoulder abduction angle at the moment of SFC (β: −2.048, p: 0.033) correlated with biomechanical efficiency and explained 45% of the variance in biomechanical efficiency. Therefore, further improvements in elbow mechanics during the arm cocking phase, based on improvements in early pitching mechanics, may help to increase pitching velocity per unit of elbow varus torque.
Modeling English vocabulary acquisition through the biomechanics of speech and Large Language Models
Authors: Shang Jingya
Published: January 2025

This study investigates the relationship between biomechanical constraints in speech production and English vocabulary acquisition by integrating Large Language Models (LLMs). Using a sample of 51 Mandarin Chinese speakers in Shenzhen, China, divided into three age groups (children: 8–12 years, adolescents: 13–17 years, and adults: 18–25 years), we conducted a 12-week longitudinal study combining articulatory measurements with computational analysis. The research employed electromagnetic articulography, surface electromyography, and advanced language modeling to examine speech patterns and learning outcomes. Results reveal significant age-related differences in articulatory kinematics, with children showing larger tongue displacements (14.3 ± 2.1 mm) and higher muscle activation levels than adults. Integrating biomechanical constraints into LLM analysis improved prediction accuracy by 18.7% for children and 14.2% for adults, though at the cost of increased computational resources. Strong negative correlations were found between articulatory effort and learning success (r = −0.824 for children, p < 0.001), with retention rates significantly influenced by motor complexity. These findings suggest that biomechanical factors play a crucial role in vocabulary acquisition, particularly in younger learners, and that incorporating these constraints into computational models can enhance our understanding of language learning processes. This integrated approach offers new insights for developing age-appropriate language teaching methodologies and improving predictive models for learning outcomes.

Published: January 2025

Background: To explore the association between the clinical phenotype of hyperthyroidism in children and the exon gene mutation locus of hyperthyroidism in children. Methods: This study collected data from 39 children with hyperthyroidism at Guangzhou Women and Children’s Medical Center in 2023. Apriori association rules are used to analyze the clinical phenotype of 39 children with hyperthyroidism and the association between exon gene mutation locus. Results: It is discovered that girls with hyperthyroidism are associated with mutations in TG, LHCGR, TSHR and other genes. Hyperthyroidism often occurs in children of school age, and the age of patients is related to the mutations of TG, TSHR and other genes. When there is no family history of hyperthyroidism, children are mostly associated with GNAS and CTLA4 gene mutations. It is also found that there is a no correlation between the gene mutation and the abnormal liver functions in children with hyperthyroidism. Mutations in DBH, LHCGR and TSHR genes are strongly associated with 2-degree goiter of the thyroid gland. The mutated genes associated with exophthalmos are GPR 1, TSHR, FSHR and LHCGR. Further findings show that the gene mutation loci (LHCGR, chr2,48688732, A > G) is strongly related to abnormal value of TPOAb, TGAb, TG and TRAb. Conclusions: These findings emphasize the significant impact of gene mutations on the development of hyperthyroidism, highlighting potential biomarkers for genetic counseling and personalized treatment methods. This study deepens our understanding of the genetic basis of hyperthyroidism in children and lays the foundation for future personalized research and genetic diagnosis based on these preliminary findings.
L'accessibilità come principio/criterio progettuale per la città di tutti
Authors: Gironda Caterina , Corazziere Chiara
Published: January 2025

La "città di tutti" rappresenta un obiettivo in continuo sviluppo verso l’accessibilità urbana, un tema che alcune città stanno già integrando, mentre altre mostrano resistenza. L’accessibilità, pur non codificata esplicitamente, riguarda la possibilità di fruire degli spazi pubblici in sicurezza e autonomia, anche per persone con disabilità motorie, sensoriali o cognitive. La Legge n. 18 del 2009 e le normative precedenti hanno introdotto misure concrete, come il Piano di Eliminazione delle Barriere Architettoniche (PEBA). Tuttavia, la sfida principale è culturale: l’accessibilità deve diventare un valore condiviso, che promuova una città inclusiva, con progetti integrati che coinvolgano urbanistica, welfare, mobilità e patrimonio culturale, creando una città che risponda ai bisogni di tutti i cittadini.
inSUPERabile Maps: Google Street View per una valutazione preliminare dell’accessibilità urbana. Un’applicazione a Catania
Authors: Manuele Gaetano Giovanni Daniele
Published: January 2025

Il piano di eliminazione delle barriere architettoniche (PEBA) è un strumento istituito per migliorare l’accessibilità degli spazi pubblici, obbligatorio per le amministrazioni locali ma poco adottato. Un metodo innovativo per mappare l’accessibilità utilizza Google Street View, che consente un rilievo preliminare delle aree. Questa metodologia è stata applicata in una porzione della città di Catania, analizzando marciapiedi in termini di accesso, dimensioni e superficie. L’approccio ha dimostrato di essere utile per identificare percorsi accessibili, semplificando il lavoro di mappatura e facilitando l’intervento sul campo.

Suolo, resilienza e difesa del territorio verso un’era post-crescita e di nuovi rischi
Authors: Cristiano Silvio
Published: January 2025

L’articolo affronta il tema del consumo di suolo, evidenziando la sua crescente rilevanza in relazione alle crisi ecologiche e alle strategie di sostenibilità. Si propone di analizzare le misure esistenti, come le linee guida della Commissione Europea per il "zero netto" nel consumo di suolo, e si mette in discussione il significato di "netto", sottolineando che questo approccio potrebbe non garantire la qualità del suolo. Nonostante le normative, il consumo di suolo in Italia continua a crescere, superando i tassi storici di urbanizzazione. L’articolo invita a riflettere sulla necessità di un cambiamento culturale e politico per affrontare seriamente la questione, considerando il suolo come una risorsa unica e non riproducibile. La rinaturalizzazione e altre pratiche devono essere integrate in un contesto più ampio per garantire un futuro sostenibile.

Authors: Martini Serena , Ravagnan Chiara , Amato Chiara
Published: January 2025

La relazione tra mobilità, infrastrutture e territorio è complessa e cruciale per lo sviluppo sostenibile, specialmente nelle aree urbanizzate. Le infrastrutture ferroviarie sono identificate come componenti strategiche per il riequilibrio territoriale e la rigenerazione urbana, andando oltre i semplici benefici trasportistici. La progettazione sostenibile delle infrastrutture, che include la condivisione degli obiettivi di sostenibilità con gli stakeholder, è fondamentale per creare valore per le generazioni future. Questo approccio integrato considera aspetti tecnici, economici, ambientali e sociali, e prevede l’adozione di metodologie e protocolli per ottenere certificazioni di sostenibilità. La Regione Lazio è un esempio di come i progetti infrastrutturali possano migliorare la mobilità e l’accessibilità, con interventi significativi come il potenziamento della linea Roma-Pescara e la chiusura dell’anello ferroviario di Roma. La collaborazione tra aziende e università, come dimostrato dal Centro nazionale della mobilità sostenibile, è essenziale per sviluppare soluzioni moderne e sostenibili.
Patient-Specific Rods vs Traditional Rods in Surgical Correction of Adult Spinal Deformities: A Case-Matched Study
Authors: Nasto Luigi Aurelio , Paolicelli Chiara , Sieczak Angelo , Ulisse Paolo , Cattolico Alessandro , Pola Enrico
Published: January 2025

AIM: Patient specific pre-contoured rods (PSRs) represent a relatively new technological development aimed at improving surgical outcomes and reducing complications in adult spinal deformity surgery. To date, only a limited number of studies have been published comparing PSRs with traditional spinal rods. In this paper, we compare the surgical, imaging, and clinical outcomes of PSRs and traditional spinal rods in a single-center case-matched study. 
METHODS: Thirty cases of adult spinal deformities (ASD) were retrospectively analysed. These included 10 patients who were operated on using UNiD™ (Adaptive Spine Intelligence, MedTronic, Minneapolis, MN, USA) PSRs and 20 operated on using traditional rods from January 2023 to August 2023. Minimum post-surgical follow-up was 6 months. General demographics and standard radiographic parameters, as well as Scoliosis Research Society (SRS)-22, Oswestry Disability Index (ODI) and Short Form Health Survey (SF-12) Scores, were measured at pre-operative examination and at 6-month follow-up. Follow-up imaging data were compared with software-planned correction goals. Intra-operative data and complications were also recorded. 
RESULTS: Patients in the two groups were matched in terms of age, body mass index (BMI), sex, type and severity of spinal deformity. The magnitude of the coronal deformity (p = 0.812) and preoperative sagittal imbalance (p = 0.845) were similar between the two groups. The number of fused levels (p = 0.439), osteotomies (p = 0.188), implant density (p = 0.880), and surgery duration (p = 0.299) were similar between the two groups. Sagittal correction goals set during preoperative planning were achieved in the PSRs group, with the exception of pelvic tilt (PT) (p = 0.042). In contrast, PT (p = 0.040), L1-S1 lordosis (p = 0.032) and global tilt (GT) (p = 0.001) remained significantly undercorrected in the control group at 6-month follow-up. Clinical outcomes (ODI and SF-12 Scores) and complication rates were similar between the two groups. 
CONCLUSIONS: The use of PSRs improves the achievement of better post-operative spinopelvic alignment in adult spinal deformity surgery. Moreover, no significant differences were noted in terms of complications, operative times, and clinical outcomes compared to traditional spinal rods at 6-month follow-up.
Understanding the Current Practice in Chest Tube Management Following Lung Resection–A Canadian National Survey
Authors: Minervini Fabrizio , Lau Esther , Begum Housne , Shargall Yaron
Published: January 2025

AIM: Timing of chest tube removal post lung resection is variable in practice and often based on personal experience rather than evidence. The current practice in chest tube management among thoracic surgeons across Canada is so far unknown. Our primary aim was to assess the current status of chest tube removal in Canada in order to uncover potential shortcomings. 
METHODS: An online anonymous survey was emailed to members of Canadian Association of Thoracic Surgeons in order to better understand the status quo of the chest tubes' removal policy in the different departments preparing the grounds for suggesting a future uniformity. Data were collected and analysed with descriptive statistics. A linear regression analysis was performed in order to understand the factors related to chest tube removal. 
RESULTS: Sixty responses were received (44.4% response rate). Most surgeons place a single chest tube in both open (75%, 45/60) and minimally invasive lobectomies (93.3%, 56/60). Digital drainage systems are used by half of the surgeons surveyed. A quarter of the respondents report removing chest tubes regardless of drainage output. This practice was independent of the surgeons' number of years in practice (p = 0.127), number of lobectomies performed annually (p = 0.877), proportion of lobectomies performed minimally invasively (p = 0.259), whether digital drainage system is used (p = 0.141) and whether the surgeon is aware of the Enhanced Recovery after Surgery (ERAS) guideline (p = 0.374). Of those who remove chest tubes based on fluid output, thresholds vary widely; a significant proportion (86%, 37/43) uses a volume lower than the 450 mL/24 h threshold set out ERAS. Most respondents (77%) were interested in a clinical trial studying chest tube removal independent of drainage volume. 
CONCLUSIONS: This study demonstrated ongoing diverse practice amongst thoracic surgeons in Canada with regards to post-operative chest tube management, indicating a much-needed area of research.
Risk Factors for Hypothermia during Laparoscopic or Open Surgery of Colorectal Cancer under General Anesthesia
Authors: Tu Yi-Hui , Zhang Di
Published: January 2025

AIM: Colorectal cancer (CRC) is one of the most prevalent malignancies, which is commonly treated with curative surgical resection, often leading to intraoperative hypothermia. Therefore, this study aimed to compare and analyze the risk factors for intraoperative hypothermia associated with laparoscopic and open CRC resections under general anesthesia.   
METHODS: This study included 120 CRC patients admitted between January 2023 and January 2024. Data from these patients were analyzed using logistic regression analysis to investigate the risk factors for hypothermia during CRC surgery. Additionally, surgical indicators such as, intraoperative bleeding volume, number of lymph nodes dissected, and operation time, and serum inflammatory markers like Interleukin-6 (IL-6) and Interleukin-8 (IL-8) were assessed and compared between the two surgical groups.   
RESULTS: The study group comprised 41 men and 79 women, with a mean age of 52.53 ± 8.90 years and an average body mass index (BMI) of 23.13 ± 3.32 kg/m2. The American Society of Anesthesiologists (ASA) score was measured as 1 for 62 (51.67%) patients and 2 for 58 (48.33%). Among them, 50 patients underwent open surgery, whereas 70 patients were treated with laparoscopic surgery. Gender, laparoscopic surgery, intraoperative fluid infusion volume, prolonged anesthesia, and intraoperative blood transfusion were determined as the independent risk factors for intraoperative hypothermia during CRC surgery under general anesthesia (p < 0.05). The intraoperative bleeding volume was significantly reduced (p < 0.01), with significantly longer operation time (p < 0.05) in patients treated with laparoscopic surgery compared to those with open surgery. However, the two groups had a similar number of lymph nodes dissected. Additionally, the levels of IL-6 and IL-8 in both laparoscopic and open surgery of patients increased significantly after surgery, but the extent of increase in the patients of laparoscopic surgery was significantly lower than that in the patients of open surgery (p < 0.05).   
CONCLUSIONS: In conclusion, gender, surgical approach, intraoperative fluid infusion volume, prolonged anesthesia, and intraoperative blood transfusion are the potential risk factors for hypothermia during laparoscopic radical CRC surgery under general anesthesia.

Authors: Wu Ben , Wu Li , He Hao , Ding Xiaogui , Bao Tong , Zhou Rui
Published: January 2025

AIM: To evaluate the efficacy of flexible ureteroscopic lithotripsy (FURL) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi based on decision tree model. 
METHODS: A total of 600 patients with ureteral calculi, including 289 treated with FURL and 311 cases with ESWL in Anqing Municipal Hospital from June 2021 to August 2023, were selected as study subjects. Perioperative indicators and stone clearance rate of the two groups were compared, and the preoperative and postoperative (24 and 72 hours) changes of serum creatinine, cystatin C (Cys-C) and microalbumin were observed. The complications during and 7 days after treatment, the influence of perioperative indexes, total stone removal rate and renal function indexes were analyzed using decision tree method, and a complication risk prediction model was constructed. 
RESULTS: The operation time, length of hospital stays and postoperative hematuria time in FURL group were shorter than those in ESWL group (p < 0.001), and the usage of painkillers was less frequent in FURL group than in ESWL group (p = 0.002). The total stone removal rate in the FURL group was higher than that in the ESWL group (p < 0.001). Serum creatinine, urinary microalbumin and Cys-C in both groups were lower before surgery than at 24 h and 72 h after surgery (p < 0.05). Serum creatinine, urinary microalbumin and Cys-C in FURL group were lower than those in the ESWL group at 24 and 72 h after operation (p < 0.001). The overall complication rate in the FURL group was lower than that in the ESWL group (p = 0.028). Decision tree model analysis showed that four explanatory variables, including preoperative creatinine, urinary microalbumin, Cys-C and surgical method were identified by screening. The risk statistic of the model was 0.027, and the accuracy, sensitivity and specificity of the model in predicting postoperative complications in patients with ureteral calculi were 97.33%, 97.73% and 97.30%, respectively. 
CONCLUSIONS: FURL has significant advantages over ESWL in the treatment of ureteral calculi, and has less impact on renal function and fewer complications. Preoperative creatinine, urinary microalbumin, Cys-C and surgical methods may adversely influence the occurrence of postoperative complications. These identified factors can be employed to build a decision tree model for predicting the occurrence of postoperative complications.

Published: January 2025

AIM: Gastric twist is a rare, however, troublesome complication of laparoscopic sleeve gastrectomy. This report describes a case complicated by perforation and leak in addition to twist. The patient was managed conservatively and successfully.   
CASE PRESENTATION: A 29-year-old female patient with a body mass index (BMI) of 41.3 kg/m2 (111 kg/1.64 m), who underwent gastric band insertion six years ago, recently experienced postprandial vomiting. Endoscopic examination revealed grade A esophagitis, minor antral gastropathy, and mild bulbar duodenitis. Her BMI was calculated at 33.1 kg/m2 (89 kg/1.64 m). One week later, she had a laparoscopic band removal and sleeve gastrectomy using an endo GIA Tri-stapler. Both the surgical and postoperative periods proceeded without complications, and she was discharged home the next day after surgery. The patient was readmitted after two weeks due to an organo-axial gastric volvulus, which was managed with stent placement. Six weeks following, a stomach leak and peri splenic fluid collection were diagnosed. A 12 mm Ovesco clip was employed to seal a perforation situated 35 cm from the incisors. Subsequently, a MEGA bariatric stent was placed. 
RESULTS: Two months after the removal of the MEGA stent, the patient had recovered completely and was in good health.   
CONCLUSIONS: Gastric twist after sleeve gastrectomy is a rare condition; a high index of suspicion is required for diagnosis. Prioritize conservative treatment to prevent the risk of revisional surgery.

Published: January 2025

Refractive surgery, which includes techniques such as Laser-Assisted In Situ Keratomileusis (LASIK), Photorefractive Keratectomy (PRK) and Small Incision Lenticule Extraction (SMILE), has revolutionized ophthalmology by offering advanced solutions for vision correction. However, the choice of the technique to be used in the individual patient is highly dependent on a thorough preoperative evaluation. This retrospective study aims to investigate how preoperative parameters, including corneal thickness, topography, and refraction, affect long-term post-operative clinical outcomes. Through a systematic review of the literature published between 2000 and 2023, we identify the main predictors of success for each surgical technique. This study emphasizes the importance of personalized surgical strategies based on meticulous preoperative analysis.

Testing physical fitness in children is essential for monitoring their physical development. The goal of this study was to determine whether there are variations inphysical fitness test results throughout the day among primary school-aged children.A total of 60 primary school children (26 girls and 34 boys), aged 10 to 12, voluntarily participated in this study. All participants completed selected physical fitnessassessments targeting cardiorespiratory fitness (CRF), strength, flexibility, and agility in two separate testing sessions—one in the morning (8:00–9:30 a.m.) and anotherin the evening (6:00–7:30 p.m.). Significant statistical differences (p < 0.01) wereobserved in the test standing long jump when comparing morning and evening results. Similarly, differences were found in the 20-meter shuttle run test in total distancecovered (p < 0.01). No other differences in physical fitness test results were observed between morning and evening sessions. Conclusions: It can be concluded that power and CRF demonstrated diurnal variation in primary school-aged children.

The article examines the profile of individuals under 18 years old who were allegedly victims of sexual violence, based on forensic examinations conducted at the Forensic Medical Institute of Belo Horizonte (IML-BH) between 2007 and 2012. The study investigates factors such as age, sex, location of the abuse, relationship to the suspect, presence of neurological deficits or psychiatric disorders in the victims, and characteristics of the injuries. The research was carried out through a retrospective analysis of 2,071 reports, excluding cases with incomplete records or victims who refused the forensic examination. The main objective was to identify patterns and characteristics that could assist in preventing and clarifying cases, as well as strengthening judicial processes. The results indicate that most victims were female adolescents, and the perpetrator often had a familial or close relationship with the victim. The study concludes that diagnosing child sexual abuse requires a multidisciplinary approach, integrating physical examination, the victim's reported history, and specific laboratory tests. It emphasizes the importance of standardizing reports and utilizing advanced technologies in the forensic context to enhance the identification and investigation of cases.

Resection of colorectal lesions such as adenomas and serrated lesions is well established for the prevention of colorectal carcinoma. Underwater endoscopic mucosal resection (UEMR), performed without submucosal injection, has been described as an alternative technique. This study aims to evaluate the feasibility, safety, and efficacy of UEMR through a prospective observational study of a non-consecutive case series conducted at a single tertiary care center between January and July 2019. Patients were referred for endoscopic resection of serrated lesions or colorectal adenomas detected during previous colonoscopic examinations. A total of 36 patients underwent UEMR for 51 colorectal lesions. The mean/median lesion size was 16.24/13 mm, and the mean/median resection time was 16.97/9.19 minutes. Histopathological evaluation revealed the following: tubular adenoma (43.1%), tubulovillous adenoma (13.7%), serrated lesions (41.2%) —of which 2 (4%) were traditional serrated adenomas, 6 (11.7%) were sessile serrated polyps, 13 (25.5%) were hyperplastic polyps—and intramucosal adenocarcinoma (2%). Complete resection was achieved in 44 of 51 lesions (86.3%). Monobloc removal occurred in 52.9% of cases, while piecemeal resection was performed in 47.1%. UEMR was endoscopically successful in 96.1% of cases. In 3.9% of cases (2 lesions), the technique was not viable, requiring conversion to conventional mucosectomy. No intestinal perforation or post-polypectomy syndrome was reported. Post-resection bleeding occurred in 6 lesions (11.8%), 5 of which were immediate and 1 delayed, all controlled endoscopically. In conclusion, UEMR proved to be a feasible, safe, and effective technique for the removal of serrated lesions and colorectal adenomas. Further randomized and controlled studies are encouraged to support the widespread adoption of this technique.
