UNASSIGNED: This prospective study aimed to investigate the influence of weight difference between implanted prosthesis and removed bone in cementless total hip arthroplasty (THA) on hip awareness and patient-reported outcomes.
UNASSIGNED: A total of 48 patients (56 hips) who underwent primary THA were prospectively enrolled. Implanted prosthesis and removed bone were weighed intraoperatively. Forgotten Joint Score (FJS) and Western Ontario and McMaster Universities (WOMAC) scores were obtained before and at 1 and 3 months after surgery. Patients were divided into groups A, B, and C according to the percentile of the weight difference.
UNASSIGNED: The mean weight difference of the implanted prosthesis and removed bone was 117.97 ± 47.35 g. A negative correlation was found among the weight differences of the three groups and 1- and 3-month postoperative FJS (correlation coefficients, -0.331 and -0.734, respectively). A positive correlation was found among the weight difference of the three groups and 3-month postoperative WOMAC (correlation coefficient, 0.403). A significant difference in 3-month postoperative FJS and WOMAC scores was found among the three groups. The mean 3-month postoperative FJS (79.00) of group C was significantly lower than that of group A (93.32) (P < 0.05). The mean WOMAC score (15.83) of group A was significantly lower than that of group C (23.67) (P < 0.05).
UNASSIGNED: The implanted prosthesis is larger than the removed bone in cementless THA. The weight difference is negatively correlated with hip function. The weight difference should be minimized to achieve optimal hip joint awareness.

BACKGROUND: Use of permanent hair dyes causes unintended oxidative damage during the short time frame of the dyeing process that leads to perceivable changes in the feel, manageability and appearance of hair. Moreover, after hair has been dyed, regular exposure to the sun as a key environmental stressor continues to stimulate additional oxidative damage and to induce newly developed hair colours to fade prematurely or undergo changes in colour quality.
OBJECTIVE: To document the utility of acetyl zingerone methyl ether (MAZ) as a newly designed haircare ingredient to afford extra protection against oxidative damage and safeguard the integrity of hair colour.
RESULTS: We demonstrate that MAZ is compatible chemically with the high alkaline conditions required for the colouring process and from theoretical calculations preferentially binds Fe and Cu ions relative to Ca or Zn ions. In model Fenton reactions MAZ effectively chelated active redox metals (Fe and Cu ions) in the presence of excess Ca+2 ions to inhibit the production of hydroxyl radicals, and in separate studies, MAZ neutralized singlet oxygen with greater efficiency than α-tocopherol by a factor of 2.5. When mixed into permanent dyes prior to hair tress application, MAZ significantly reduced combing forces, and SEM images led to substantial reductions in visual signs of surface damage. In a 28-day clinical study, relative to controls, mixing MAZ into hair dyes prior to application interfered neither with colour development nor with ability to cover grey hair and led to significant improvements in perceived attributes associated with hair\'s condition immediately following the dyeing process. Over a 28-day maintenance phase, especially between Day 14 and Day 28, continued use of shampoo and conditioner containing MAZ significantly preserved gloss measurements and hair colour in terms of longevity and colour quality as remaining desired and fresh compared to use of control shampoo and conditioner.
CONCLUSIONS: This work establishes MAZ as a next-generation hair care ingredient for use in permanent dyes to attenuate oxidative damage and in shampoos and conditioners to promote longevity of hair colour and to maintain overall health and appearance of hair on a daily basis.
BACKGROUND: L\'utilisation de colorants capillaires permanents provoque des dommages oxydatifs involontaires pendant la courte période du processus de teinture, ce qui entraîne des changements perceptibles dans la texture, la maniabilité et l\'aspect des cheveux. De plus, après la teinture des cheveux, une exposition régulière au soleil comme facteur de stress environnemental clé continue de stimuler des dommages oxydatifs supplémentaires et d\'induire une décoloration prématurée des nouvelles couleurs de cheveux ou des changements dans la qualité de la couleur.
OBJECTIVE: Documenter l\'utilité de l\'éther méthylique d\'acétyl zingérone (MAZ) en tant qu\'ingrédient de soin capillaire nouvellement conçu pour offrir une protection supplémentaire contre les dommages oxydatifs et sauvegarder l\'intégrité de la couleur des cheveux. RÉSULTATS: Nous démontrons que le MAZ est chimiquement compatible avec les conditions alcalines élevées requises pour le processus de coloration et, d\'après les calculs théoriques, lie de préférence les ions Fe et Cu aux ions Ca ou Zn. Dans les réactions de Fenton, le MAZ chélate efficacement les métaux redox actifs (atomes de Fe et de Cu) en présence d\'un excès d\'ions Ca+2 pour inhiber la production de radicaux hydroxyles et, dans des études séparées, le MAZ neutralise l\'oxygène seul avec une efficacité supérieure à celle de l\'α‐tocophérol, d\'un facteur de 2.5. Lorsqu\'il est mélangé à des teintures permanentes avant l\'application de la coiffure, le MAZ réduit de manière significative les forces de peignage et, d\'après les images SEM, conduit à des réductions substantielles des signes visuels de dommages à la surface. Dans une étude clinique de 28 jours, le mélange de MAZ dans les teintures capillaires avant l\'application n\'interfère pas avec le développement de la couleur ni avec la capacité à couvrir les cheveux gris et conduit à des améliorations significatives des attributs perçus associés à l\'état des cheveux immédiatement après le processus de teinture. Au cours d\'une phase d\'entretien de 28 jours, en particulier entre le 14ème et le 28ème jour, l\'utilisation continue du shampooing et de l\'après‐shampooing contenant du MAZ a permis de préserver de manière significative les mesures de brillance et la couleur des cheveux en termes de longévité et de qualité de la couleur, qui reste telle que désirée et nette, par rapport à l\'utilisation du shampooing et de l\'après‐shampooing de contrôle.
CONCLUSIONS: Ces travaux font du MAZ un ingrédient de nouvelle génération pour les soins capillaires, à utiliser dans les teintures permanentes pour atténuer les dommages oxydatifs et dans les shampooings, et après‐shampooings pour promouvoir la longévité de la couleur des cheveux et maintenir la santé et l\'apparence générales des cheveux au quotidien.

UNASSIGNED: Segmental spinal deformity results from vertebral compression fracture (VCF) and progressive collapse of the fractured vertebral body (VB). The VB stenting (VBS) systemⓇ comprises a balloon-assisted, expandable, intrasomatic, metal stent that helps maintain the restored VB during balloon removal and cement injection, which minimizes cement leakage. We performed a prospective, multicenter, clinical trial of the VBS system in Japanese patients with acute VCF owing to primary osteoporosis.
UNASSIGNED: Herein, 88 patients, 25 men and 63 women aged 77.4±8.3 years, with low back pain, numerical rating scale (NRS) score of ≥4, and mean VB compression percentage (VBCP) of <60% were enrolled. The primary endpoints were the VBCP restoration rate and reduction in low back pain 1 month and 7 days after VBS surgery, respectively. Secondary endpoints included changes in VBCP, NRS pain score, Beck index, kyphosis angle, and quality of life according to the short form 36 (v2) score. Safety was assessed as adverse events, device malfunctions, and new vertebral fractures.
UNASSIGNED: Overall, 70 patients completed the study. VBS surgery increased the restoration rates of anterior and midline VBCP by 31.7%±26.5% (lower 95% confidence intervals (CI): 26.8) and 31.8%±24.6% (lower 95% CI: 27.2), respectively, and the reduction in NRS pain score was -4.5±2.4 (upper 95% CI: -4.0). As these changes were greater than the predetermined primary endpoint values (20% for VBCP and -2 for NRS score), they were judged clinically significant; these changes were maintained throughout the 12-month follow-up (p<0.001). Likewise, significant improvement was observed in the Beck index, kyphosis angle, and quality of life score, which were maintained throughout the follow-up. There were three serious adverse events. New fractures occurred in 12 patients-all in the adjacent VB.
UNASSIGNED: VBS surgery effectively restored the collapsed VB, relieved low back pain, and was tolerable in patients with acute osteoporotic VB fracture.

Prostate cancer (PCa) is a common male malignancy and early diagnosis is crucial for successful treatment. The current study aims to validate results from a pilot study that demonstrated an inverse association between urine tyrosine and tryptophan levels and the severity of PCa. This study comprised a cohort of 97 patients with benign prostatic hyperplasia, 93 patients diagnosed with localized PCa, 75 patients diagnosed with locally advanced PCa, and 68 patients diagnosed with metastatic PCa. The tyrosine and tryptophan levels in the samples were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) and electrochemical sensors in accordance with the pilot to maintain uniformity for accurately evaluating the data. One-way ANOVA with post Tukey test as well as the Wilcoxon Rank Sum Test were performed. Analyzing 333 patients across PCa stages with consistent methods, we observed no significant differences in tyrosine and tryptophan levels between PCa patients and controls, finally rejecting the use of tyrosine and tryptophan as PCa biomarkers. We did, however, verify the strong correlation between the urinary concentrations of tyrosine and tryptophan found in the pilot study.

OBJECTIVE: To evaluate the trueness of dental arches digitised by two intraoral scanning (IOS) technologies from patients presenting crowding, diastema, and bilateral posterior edentulous space with tilted molar.
METHODS: Conventional impressions and dental stone models were generated from three patients presenting the aforementioned dental arch conditions. These models were digitised on a desktop scanner, and the resulting mesh was used as reference. Subsequently, the patients were scanned using confocal based (CF; iTero Element 2) and blue laser-multiscan (BLM; Virtuo Vivo) imaging IOS technology, totalling thirty scans. The meshes from the scans were exported in Standard Tessellation Language format and analysed using Geomagic Control X software. Root mean square (RMS) indicated deviation magnitude. Differences in IOS technologies were evaluated with paired t-tests, and dental arch conditions compared using ANOVA and post-hoc Tukey tests (α=0.05).
RESULTS: Digital dental arch from blue laser-multiscan technology showed lower trueness compared to confocal based technology for crowding (p = 0.0084) and edentulous spaces (p = 0.0025) conditions. When the types of oral condition were compared, discrepancies were significantly different for both IOS technologies, featuring the arch with diastema showing the lowest trueness, followed by edentulous spaces and crowding.
CONCLUSIONS: Dental arches presenting crowding and edentulous spaces digitised by blue laser-multiscan technology exhibited greater discrepancies compared to confocal based imaging technology. Furthermore, trueness varied among the dental arch conditions.
CONCLUSIONS: The IOS technology and patient\'s dental arch condition can influence the trueness of dental arch digitisation. Being aware of these effects allows clinicians to take them into account during scanning procedures, digital planning and manufacturing.

This study aimed to identify factors associated with a strong home blood pressure (BP)-lowering effect of esaxerenone and the incidence of elevated serum potassium levels in hypertensive patients treated with esaxerenone. A pooled analysis of five multicenter, prospective, open-label single-arm studies was conducted, including 479 patients in the full analysis set (FAS) and 492 patients in the safety analysis set. Multivariate linear regression analysis of morning home systolic BP (SBP) and diastolic BP (DBP) changes from baseline to Week 12 in the FAS (primary endpoint) showed that male sex (estimated change 4.37 mmHg), office pulse rate ≥100 beats/min (25.10 mmHg), and calcium channel blocker (CCB) use as a basal antihypertensive agent (4.53 mmHg) were significantly associated with a positive estimated change (weaker BP-lowering effect) in morning home SBP. CCB use (3.70 mmHg) was associated with a positive estimated change in morning home DBP. Urine albumin-to-creatinine ratio 30 to <300 mg/gCr (-4.13 mmHg) was significantly associated with a negative estimated change (stronger BP-lowering effect) in morning home SBP. Based on multivariate logistic regression analysis, elevated baseline serum potassium level (≥4.5 vs < 4.5 mEq/L, odds ratio 13.502) was significantly associated with a high incidence of serum potassium level ≥5.5 mEq/L after esaxerenone treatment. In conclusion, factors associated with a strong BP-lowering effect of esaxerenone were female sex and use of renin-angiotensin system inhibitors as a basal antihypertensive drug. Patients with baseline serum potassium levels ≥4.5 mEq/L had an increased risk of developing elevated serum potassium levels (≥5.5 mEq/L) after esaxerenone treatment.

BACKGROUND: Incomplete revascularization (ICR) has been associated with a worse prognosis after a percutaneous coronary intervention (PCI). In NSTEMI patients with multivessel disease (MVD) however, the benefit of a complete revascularization (CR) remains unclear.
METHODS: Patients presenting with an NSTEMI and MVD were selected from the global e-ULTIMASTER registry and grouped according to completeness of revascularization at index hospitalization discharge. The primary endpoint was the patient oriented composite endpoint (POCE) defined as all death, any myocardial infarction, and any revascularization at 1 year. Target lesion failure (TLF) was defined as the composite of cardiac death, target vessel related myocardial infarction and clinically driven target lesion revascularization. Inverse propensity score weighting (IPSW) was performed to harmonize the patient\'s baseline characteristics between the groups.
RESULTS: CR was achieved in 1800 patients (47.0 %) and ICR in 2032 patients (53.0 %). The incidence of POCE at 1 year was lower in the CR group compared to the ICR group: 7.0 % vs. 12.9 %, p < 0.0001. Similarly for TLF at 1 year: 3.6 % vs. 5.5 %, p < 0.01. After IPSW, the incidence of POCE was 7.7 % vs. 12.0 %, p < 0.0001, due to a lower all-cause mortality: 2.7 % vs. 4.2 %, p = 0.02 and less revascularizations: 4.9 % vs. 7.9 %, p < 0.001. The incidence of TLF was no longer statistically significant: CR 3.9 % vs. IR 5.0 %, p = 0.10.
CONCLUSIONS: Patients with a NSTEMI and multi vessel disease undergoing a percutaneous coronary revascularization with a complete revascularization during index hospitalization have better 1-year clinical outcomes. Randomized studies are warranted to confirm these results.

OBJECTIVE: This 2-year prospective study reports the incidence of prosthetic complications and maintenance events after treatment with mandibular overdenture retained by four mini implants opposed to a maxillary denture.
METHODS: Implant intervention included flapless or flapped surgery combined with immediate or delayed loading, as part of a randomized clinical trial. Four one-piece titanium-zirconium mini-implants (Straumann Mini Implant System) were inserted, and the retentive PEEK elements (Optiloc) were incorporated into the overdenture using chairside procedures. Prosthodontic complications and maintenance events were recorded over a 2-year follow-up, and the final outcome was defined according to standardized criteria. Data analysis included descriptive statistics, incidence and incidence density rates, and Kaplan-Meier survival.
RESULTS: 73 out of 74 patients (64.9 % female), mean age of 64 (SD=8.2) years, completed the study follow-up (one withdrew after 9 months). Implant survival was 100 %. A total of 163 prosthodontic events occurred in 53 patients (72.6 %), and 20 patients had no clinical complaints or maintenance needs. The most common procedures were adjustment/repair of the overdenture base (47.0 %), replacement of retentive inserts (19.8 %), and laboratory relining (12.9 %). A high prosthodontic success rate was achieved (93.2 %), and all patients presented serviceable overdentures and continuous use after the resolution of prosthodontic complications. The incidences of matrix replacement and laboratory relines were low in the first year, while denture base adjustments were common within the first year, especially in the first 6 months.
CONCLUSIONS: The mini implant system showed high prosthodontic success rates. Minor adjustments/repairs during the initial follow-up were common. Relines and matrix replacements tend to occur after one year of overdenture use, and matrix replacements may occur as a consequence of the need for relining.

This study investigates the impact of nonsurgical periodontal treatment (NSPT) on oral health-related quality of life (OHRQoL) in patients with periodontitis stages (S)2 and S3, and the factors associated with the prediction of patient-reported outcomes. Periodontitis patients (n = 68) with moderately deep periodontal pockets were recruited. Responses to the Oral Health Impact Profile (OHIP)-14 questionnaire and clinical parameters including plaque index, bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment loss (CAL) were recorded. All patients received supra- and subgingival professional mechanical plaque removal. All clinical parameters and questionnaire responses were recorded again 3 months after NSPT. Clinical parameters and OHIP-14 scores for both stages of periodontitis were significantly improved 3 months after treatment. However, participants with periodontitis S3 had significantly higher total OHIP-14, physical pain, and functional limitation domains scores than periodontitis S2 cases. Baseline CAL, BOP, and the presence of PPD in anterior teeth were positively associated with increased OHIP-14 scores after NSPT. NSPT improved OHRQoL in participants with periodontitis S2 and S3. This was more pronounced in participants having periodontitis S3 than S2. Poorer OHRQoL could be anticipated in people having severe CAL, high BOP, and presence of pockets in the anterior teeth.

OBJECTIVE: To explore the causal relationship between inflammatory protein markers and the risk of colorectal cancer using a Mendelian randomization (MR) approach.
METHODS: We obtained data pertaining to colorectal cancer from Genome-Wide Association Study (GWAS) datasets and used 91 inflammatory protein markers as the exposure variables. A two-sample MR analysis model was used to assess the causal link between the inflammatory markers and colorectal cancer risk. The robustness of the results was evaluated through heterogeneity, pleiotropy, and sensitivity analyses using 5 MR models: Inverse Variance Weighted (IVW), Weighted Median, MR Egger, Simple Mode, and Weighted Mode. We examined the mRNA expressions of PD-L1, AXIN1, and β-NGF using RT-qPCR in 86 untreated patients with colorectal adenocarcinoma admitted in Nanfang Hospital between December, 2021 and December 2023, and analyzed their correlation with the clinical characteristics of the patients.
RESULTS: Using the IVW model, MR analysis revealed significant causal associations between a reduced risk of colorectal cancer and lowered expressions of AXIN1 (OR=0.866, 95% CI: 0.754-0.994, P=0.040), β-NGF (OR=0.914, 95% CI: 0.843-0.990, P=0.028; OR=0.884, 95% CI: 0.784-0.998, P=0.047 using Weighted Median model), and PD-L1 (OR=0.903, 95% CI: 0.824- 0.989, P=0.028). No significant heterogeneity or pleiotropy was observed, indicating good stability of the results. Sensitivity analysis confirmed the reliability of the findings. The clinical study demonstrated a significant correlation between PD-L1 expression and TNM staging, particularly in stage Ⅳ patients (P=0.007). AXIN1 and β -NGF expression levels were significantly correlated with the degree of tumor differentiation, and their expressions were higher in poorly differentiated samples (P<0.001).
CONCLUSIONS: Lowered expressions of inflammatory protein markers AXIN1, β-NGF, and PD-L1 are causally correlated with a reduced risk of colorectal cancer and their expression levels are associated with TNM staging and tumor differentiation. These markers may thus serve as potential targets for colorectal cancer treatment and prevention.
