Dental Implant Rehabilitation in Patients Carrying WNT10A Mutations With Different Molecular Statuses and Phenotypes: A Retrospective Cohort Study.

WNT10A mutations are associated with tooth agenesis. This study aimed to assess the clinical outcomes of dental implants in patients carrying WNT10A mutations with different molecular statuses and phenotypes over a long-term follow-up period. Patients with tooth agenesis were screened by whole-exome sequencing (WES) from January 2010 to September 2023. Carriers of pathogenic WNT10A mutations who underwent subsequent dental implant therapy were evaluated. WES identified 66 patients with tooth agenesis carrying WNT10A mutations. Of these, 27 patients (11 males/16 females; mean age 19.6 years) met the inclusion criteria. Homozygotes had significantly more missing teeth (24.4 ± 3.8) than heterozygotes (10.9 ± 5.1, p < 0.0001) and compound heterozygotes (13.8 ± 3.5, p = 0.001). A total of 160 conventional implants were placed. Seven implants were lost in four patients before final prosthesis placement, resulting in overall failure rates of 14.8% at the subject level and 4.4% at the implant level. The 5-year cumulative survival rate (range: 0.23-12.74 years) was 85.2% and 95.6% at the subject and implant levels, respectively. The mean marginal bone loss (MBL) was 0.80 mm (95% CI: 0.59-1.02). Subgroup analysis revealed higher MBL in homozygotes (p = 0.002), sites requiring extensive bone augmentation (p = 0.016), anterior regions (p = 0.031), and full-arch bridge cases (p < 0.0001). Patient satisfaction and OHIP-C49 scores were favorable. Implant rehabilitation is predictable for patients with WNT10A mutations. However, increased MBL observed in homozygotes with severe tooth agenesis and in cases requiring extensive alveolar bone augmentation highlights the importance of genetic diagnosis prior to implant therapy in patients with severe tooth agenesis.

Clinicopathological characteristics and predictors of renal outcomes in diffuse crescentic glomerulonephritis : a retrospective single-center study from Western China

BackgroundThe factors influencing diffuse crescentic glomerulonephritis renal survival and prognosis remain uncertain. Additionally, there’s no literature on the clinical outcomes of IgA nephropathy, lupus nephritis, and IgA vasculitis nephritis in type II patients.MethodsThis study retrospectively examined 107 patients diagnosed with diffuse crescentic glomerulonephritis through biopsy. Analytical methods included Cox regression models and Kaplan-Meier survival analysis to assess the data.ResultsAmong the 107 enrolled patients, 12 patients had Type I diffuse crescentic glomerulonephritis, 70 patients had Type II, and 25 patients had Type III. The respective 5-year kidney survival rates were 0%, 57.5%, and 18.6% for type I, type II, and type III. Furthermore, among Type II patients, IgA nephropathy emerged as the most prevalent condition. The cumulative 5-year kidney survival rates were 50% for patients with IgA nephropathy, 64% for lupus nephritis, and 70% for Henoch-Schönlein purpura nephritis. A significant association between the risk of ESKD development and several factors was revealed by a multivariate Cox regression analysis: estimated glomerular filtration rate (P = 0.004), initial kidney replacement therapy (KRT) at presentation (P = 0.002), global glomerulosclerosis (P<0.001).ConclusionsType II diffuse crescentic glomerulonephritis was the most prevalent type in DCGN, and favors better renal prognosis than type I and III DCGN, in which IgA nephropathy was the most common entity of Type II DCGN. Additionally, estimated glomerular filtration rate, initial KRT at presentation and global glomerulosclerosis were identified as predictors of renal outcomes in diffuse crescentic glomerulonephritis.

Blood urea nitrogen-to-albumin ratio as a new prognostic indicator of 1-year all-cause mortality in patients with IPF.

Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease characterized by chronic inflammation and progressive fibrosis. The blood urea nitrogen-to-albumin ratio (BAR) is a comprehensive parameter associated with inflammation status; however, it is unknown whether the BAR can predict the prognosis of IPF. This retrospective study included 176 patients with IPF, and 1-year all-cause mortality of these patients was recorded. A receiver operating characteristic (ROC) curve was used to explore the diagnostic value of BAR for 1-year all-cause mortality in IPF patients, and the survival rate was further estimated using the Kaplan-Meier survival curve. Cox proportional hazards regression model and forest plot were used to assess the association between the BAR and 1-year all-cause mortality in IPF patients. The BAR of IPF patients was significantly higher in the non-survivor group than in the survivor group [0.16 (0.13-0.23) vs. 0.12 (0.09-0.17) mmol/g, p = 0.002]. The area under the ROC curve for predicting 1-year all-cause mortality in IPF patients was 0.671, and the optimal cut-off value was 0.12 mmol/g. The Kaplan-Meier survival curve showed that the 1-year cumulative survival rate of IPF patients with a BAR ≥0.12 was significantly decreased compared with the patients with a BAR <0.12. The Cox regression model and forest plot showed that the BAR was an independent prognostic biomarker for 1-year all-cause mortality in IPF patients (HR = 2.778, 95% CI 1.020-7.563, p = 0.046). The BAR is a significant predictor of 1-year all-cause mortality of IPF patients, and high BAR values may indicate poor clinical outcomes.

Impact of Standardized Heart Failure Management Center Construction on the Management of Patients With Chronic Heart Failure.

Heart failure is extremely harmful to human health and social economics. The purpose of standardized heart failure management center (SHFMC) is to correct the non-standardization of heart failure treatment. SHFMC has a positive impact on the management and prognosis of patients with chronic heart failure (CHF). The SHFMC database of Jiaxing First Hospital was retrospectively analyzed. Two hundred sixty-three patients with CHF who were hospitalized in the cardiovascular medicine department of Jiaxing First Hospital in Zhejiang Province from January 2020 to December 2020 were identified as study subjects. The SHFMC opening day, July 1, 2020, was used as the dividing line around which the patients were divided into Group A (before the completion of SHFMC, n = 137) and Group B (after, n = 126). The baseline data, treatment standardization, long-term efficacy, 1-year all-cause mortality, and readmission rate of the two groups were compared. The use of angiotensin receptor enkephalinase inhibitors (ARNIs), β-blockers (β-Bs), and sodium-glucose cotransport protein 2 inhibitors (SGLT2is) increased significantly, and the long-term outcome, readmission rate, and 1-year all-cause mortality of patients improved in group B. The construction of SHFMC has been associated with consistent improvements in the standardization of CHF treatment, long-term patient outcomes, 1-year cumulative survival rates, and readmission rates.

Minimally invasive glass-ceramic restorations: Clinical and patient-reported outcomes in full-mouth rehabilitations.

To evaluate clinical outcomes (restoration survival, technical and biological complications), and patient-reported outcome measures (PROMs) of full mouth rehabilitation with minimally invasive glass-ceramic restorations after up to 12 years of clinical service. Twenty individuals (12 females, 8 males) received full-mouth rehabilitation with minimally invasive tooth-supported glass-ceramic restorations during the years 2009 - 2017 and agreed to participate in a follow-up visit. Full dental and periodontal examinations were completed, and the restorations were evaluated according to United States Public Health Service (USPHS) criteria. Kaplan-Meier was used for analysis of the survival time. The patients received 439 minimally invasive restorations made from lithium disilicate reinforced glass-ceramic (79.7%), feldspathic porcelain (17.5%) and leucite reinforced glass-ceramic (2.7%). Restoration design included occlusal and buccal surface partial coverage restorations (35.3%), full-contour restorations (31.2%), veneers (27.8%), onlays (4.6%) and inlays (1.1%). The mean follow-up time from restoration insertion was 4.5 years (1.5-12.4 years). Five patients lost altogether 13 restorations during the follow-up time. The estimated cumulative Kaplan-Meier 5-year survival rates were 96.6% on the restoration level and 86.4% on the patient level. Major technical complications amounted to 3% (n = 13) of the restorations, including larger chippings (n = 5) and loss of retention (n = 7). Biological complications were observed at a rate of 4.3%. Patients were very satisfied with esthetics (VAS 9.5) and function (VAS 9.3) of the restorations. Minimally invasive full-mouth rehabilitation with glass-ceramic restorations resulted in high survival rates, few complications and a high level of patient satisfaction over a mid-term time-period. There is an increasing trend toward minimally invasive restorations, as previous studies indicate that these designs preserve healthy tooth structure, leading to fewer biological complications. The present study demonstrates that minimally invasive restorations can be reliably used in full-mouth rehabilitations.

Analysis of long-term outcomes after surgical treatment of patients with complicated forms of colon cancer

The aim of the study. To evaluate long-term outcomes in patients who underwent surgery due to complications of colon cancer in a general surgical hospital. Materials and methods. The study group included 71 (100 %) patients with complicated forms of colon cancer. Radical surgical interventions were performed in 48 (67.6 %) patients, palliative cytoreductive operations – in 18 (25.4 %) hospitalized patients, symptomatic – in 5 (7.0 %) patients. Results. In the postoperative period, only 37 (58.7 %) patients sought help from an oncologist at the third level of medical care. The remaining 26 (41.3 %) patients refused to consult an oncologist and specific treatments for whatever reason. Conclusions. Of the 37 (58.7 %) operated patients who sought oncological care, a chemotherapy course was initiated for 19 (51.4 %), dynamic follow-up without specific treatments was recommended for 7 (18.9 %) patients and symptomatic treatments according to the standards of palliative medical care – for 9 (24.3 %). During the follow-up period, among 43 (68.3 %) patients with non-metastatic cancer, 6 (14.0 %) of the operated patients had local recurrences, 8 (18.6 %) – regional, and 12 (27.9 %) – distant ones. In 17 (39.5 %) patients, no findings on recurrent colon cancer were revealed. Cumulative 1-year and 3-year survival rates in this category of patients were 56.3 ± 5.9 % and 38.0 ± 5.8 %, respectively.

Survival of People Living with HIV/AIDS from Pre-ART Era to Treat-all Era - China, 1985-2022.

A comprehensive analysis of nationwide survival trends for people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS, PLWHA) from the initial reported case to present has not been conducted. This study evaluated the survival outcomes of PLWHA reported in China from 1985 to 2022. We analyzed data from PLWHA recorded in the National HIV/AIDS Comprehensive Response Information Management System from 1985 to 2022. Survival rates were calculated using Kaplan-Meier curves, and factors associated with survival time were analyzed using Cox proportional hazard models. Progressive relaxation of antiretroviral therapy initiation criteria led to significant improvements in survival rates across different diagnostic periods in China. The 1-year and 5-year cumulative survival rates increased from 85.2% and 66.1% in the 1985-2003 cohort to 91.1% and 81.4% in the 2016-2022 cohort. Cox proportional hazard analysis revealed elevated mortality risks among males, individuals aged ≥65 years, those with injection drug use or other transmission routes, hospital-tested patients, and those with lower CD4 counts at diagnosis or without treatment. Antiretroviral therapy has effectively reduced mortality risk among PLWHA in China. Future efforts should focus on expanding HIV testing to reduce the proportion of late diagnoses with lower CD4 counts and providing targeted, differentiated services for older populations to further decrease mortality risk among PLWHA.

Individual approach to the treatment of patients with stage III–IV laryngeal and laryngopharyngeal cancer in the Altai territory

Laryngeal and laryngopharyngeal cancer is the most common malignancy within the head and neck. Although there are many treatments for laryngeal and laryngopharyngeal cancer, the treatment still faces great challenging.The aim of the study was to evaluate the effectiveness of personalized treatment and one-year recurrence-free survival in patients with stage III–IV laryngeal and laryngopharyngeal, including postoperative complications (VTE, bleeding) within a year.Material and Methods. From July 2022 to October 2023, 100 patients with stage III–IV laryngeal and laryngopharyngeal cancer were treated in the Department of Head and Neck Tumors at the Altai Regional Oncology Center (AROC), Barnaul. There were 95 men (95 %) and 5 women (5 %). Patients were divided into two groups. Group I patients (n=50) with locally advanced laryngeal cancer underwent laryngectomy followed by radiation therapy with a total dose of 54 Gy delivered to the bed of the removed tumor and lymph node drainage region. Group II patients (n=50) received 3 courses of chemotherapy followed by radiation therapy at a dose of 70–74 Gy.Results. In group I patients, clinically insignifcant bleeding from the upper third of the trachea (in the area of contact with the tracheostomy tube) was observed in 3 patients (6.0 %) 3–4 days after surgery. No VTE during hospital stay and within 6–12 months after completion of treatment was observed. The 1-year cumulative survival rate in this group of patients was 90.0 %. In group II patients receiving chemotherapy, bleeding from a pharyngeal tumor was detected in 4 (8.0 %) patients. There were no signs of VTEO in this group. The 1-year cumulative survival rate of these patients was 70 %.Conclusion. Patients with laryngeal/laryngopharyngeal cancer require an individual approach not only in determining therapeutic strategies, but also in the prevention of VTE and hemorrhagic complications.

Association between Left Atrial Function and Survival in Systemic Sclerosis.

Systemic sclerosis (SSc) is a multisystemic autoimmune disorder in which cardiac involvement is frequent and portends negative prognosis. Left ventricular (LV) diastolic dysfunction is one of the most common cardiac alterations in these patients, and left atrial (LA) reservoir strain (ƐR) measurement using speckle tracking echocardiography has been proposed as a novel parameter for a better assessment of LV diastolic function. Therefore, the aim of this study was to test the prognostic value of ƐR in a large multicenter cohort of SSc patients. In total, 311 SSc patients (54 ± 14 years, 85% female) were included from two different centers. Echocardiography was performed at the time of first visit, including ƐR measurement. Over a median follow-up of 132 (interquartile range: 110 to 157) months, 67 (21.5%) patients experienced the outcome of all-cause mortality. Spline curve analysis identified an optimal cut-off value of 30% for ƐR, and patients with ƐR ≤ 30% showed a 10-year cumulative survival rate of 71% as compared to 88% for patients with ƐR > 30% (log-rank p < 0.001). At the multivariable Cox regression analysis, ƐR was independently associated with the endpoint (HR 1.830; 95% confidence interval (CI) 1.031-3.246; p = 0.039) together with age (HR 1.071, 95% CI 1.043 to 1.099; p < 0.001), sex (female) (HR 0.444, 95% CI 0.229 to 0.861; p = 0.016), and diffusing lung capacity for carbon monoxide (HR 0.969 95% CI 0.956 to 0.982; p < 0.001). ƐR is of independent prognostic value in SSc and might help optimizing risk stratification in these patients.

10-Year Survival Rate of 82% Following 262 Cases of Arthroscopic Bone Marrow Stimulation for Osteochondral Lesions of the Talus

Category: Arthroscopy; Ankle Introduction/Purpose: The long-term sustainability of arthroscopic bone marrow stimulation (BMS) for osteochondral lesions of the talus (OLT) remains a matter of debate. The primary aim of the present study is to assess the 10-year survival following arthroscopic BMS for OLT. The secondary aim is to evaluate the influence of baseline patient- and lesion characteristics on survival. Methods: Patients who underwent arthroscopic BMS for a symptomatic OLT with a minimum follow-up of 10-years were included to assess procedure survival. The primary outcome, the 10-year cumulative survival rate, was analysed with a Kaplan-Meier survival analysis. Secondary outcomes concerned the median time to survival and the effect of baseline factors (i.e., lesion size, primary or non-primary lesion type, preoperative cysts, and obesity (body mass index ≥30 kg/m²) on survival and was analysed with a cox-regression model and reported with hazard ratios (HR). Results: From the 262 patients included at a mean 15.3 ± 4.8 years follow-up, the 10-year cumulative survival rate of arthroscopic BMS was 82% [95%-CI: 77% - 87%]. At 15-years follow-up the cumulative survival rate was 82% [95%-CI: 76% - 86%]. The median time to revision was 2.4 (interquartile range: 1.3 – 5.1) years. Of the baseline factors, obesity (HR: 3.0 [95%-CI: 1.44 – 6.43], p= &lt; 0.01) was associated with decreased survival. Lesion size (HR: 0.9 [95%-CI: 0.5– 1.8] p= 0.8), non-primary lesion type (HR: 1.8 [95%-CI: 0.9 – 3.4] p= 0.1), and the presence of preoperative cysts (HR: 1.0 [95%-CI: 0.6 – 1.9] p= 0.9) were not significantly associated with survival. Conclusion: At a minimum follow-up of 10-years, the survival rate of arthroscopic BMS for OLT was 82%. At 15- and 20-years follow-up survival seems to remain stable. Obesity (BMI ≥30 kg/m2) was associated with a higher likelihood of revision surgery. This risk factor should be incorporated into the treatment algorithm for OLT when counselling patients for surgery.

Treatment strategies for patients over 80 years of age with oral squamous cell carcinoma

ObjectiveTo analyze the clinical characteristics of patients with oral squamous cell carcinoma aged ≥80 years, focusing on surgical treatments. Study DesignWe reviewed patients with oral squamous cell carcinoma aged ≥80 years who underwent surgery between 2005 and 2018. Basic information, comorbidities, multiple primary cancers, initial treatment, complications, and outcomes were evaluated. ResultsOf 197 patients aged ≥80 years, 119 patients underwent surgery (50 males, 69 females; mean age: 83.5 years). The gingiva was the most common primary tumor site (63 patients, 52.9%). The stage classification was stage I in 35 patients (29.4%), stage II in 44 (37%), stage III in 16 (13.4%), stage IVA in 22 (18.5%), and stage IVB in 2 (1.7%). Comorbidities were identified in 112 patients (94.1%). Surgery was the initial treatment in 111 patients (93.3%). Eight (6.7%) patients received postoperative adjuvant chemotherapy/radiotherapy; 20 patients (16.8%) underwent free tissue transplantation. Perioperative complications were observed in 36 patients (30.3%). The cumulative 5-year and 10-year overall survival rates were 82% and 68.3%, respectively; the disease-specific survival rates were 90%. ConclusionGood treatment outcomes were obtained with radical surgery. Surgery should be the first choice if quality of life is assured and there are no issues with surgical tolerance, regardless of age.

Analysis of vascular thrombus and clinicopathological factors in prognosis of gastric cancer: A retrospective cohort study

BACKGROUND Gastric cancer (GC) is one of the most common malignant tumors in the world, and its prognosis is closely related to many factors. In recent years, the incidence of vascular thrombosis in patients with GC has gradually attracted increasing attention, and studies have shown that it may have a significant impact on the survival rate and prognosis of patients. However, the specific mechanism underlying the association between vascular thrombosis and the prognosis of patients with GC remains unclear. AIM To analyze the relationships between vascular cancer support and other clinicopathological factors and their influence on the prognosis of patients with GC. METHODS This study retrospectively analyzed the clinicopathological data of 621 patients with GC and divided them into a positive group and a negative group according to the presence or absence of a vascular thrombus. The difference in the 5-year cumulative survival rate between the two groups was compared, and the relationships between vascular cancer thrombus and other clinicopathological factors and their influence on the prognosis of patients with GC were analyzed. RESULTS Among 621 patients with GC, the incidence of vascular thrombi was 31.7% (197 patients). Binary logistic regression analysis revealed that the degree of tumor differentiation, depth of invasion, and extent of lymph node metastasis were independent influencing factors for the occurrence of vascular thrombi in GC patients (P &lt; 0.01). The trend of the χ 2 test showed that the degree of differentiation, depth of invasion, and extent of lymph node metastasis were linearly correlated with the percentage of vascular thrombi in GC patients (P &lt; 0.01), and the correlation between lymph node metastasis and vascular thrombi was more significant (r = 0.387). Univariate analysis revealed that the 5-year cumulative survival rate of the positive group was significantly lower than that of the negative group (46.7% vs 73.3%, P &lt; 0.01). Multivariate analysis revealed that age, tumor diameter, TNM stage, and vascular thrombus were independent risk factors for the prognosis of GC patients (all P &lt; 0.05). Further stratified analysis revealed that the 5-year cumulative survival rate of stage III GC patients in the thrombolase-positive group was significantly lower than that in the thrombolase-negative group (36.1% vs 51.4%; P &lt; 0.05). CONCLUSION Vascular cancer status is an independent risk factor affecting the prognosis of patients with GC. The combination of vascular cancer suppositories and TNM staging can better judge the prognosis of patients with GC and guide more reasonable treatment.

Clinical Outcomes of Pterygoid and Maxillary Tuberosity Implants: A Systematic Review.

Background: This study aimed to assess the survival of implants placed in the maxillary tuberosity or in the pterygomaxillary region of the maxilla, based on a systematic review of the literature. Methods: An electronic search was undertaken in three databases. The cumulative survival rate (CSR) was calculated. The log-rank (Mantel-Cox) test was used to compare the survival distributions between some groups. Results: Thirty-eight studies were included, reporting 3446 implants (3053 pterygoid, 393 tuberosity) in 2245 patients, followed up for a mean ± SD of 61.0 ± 36.3 months (min-max, 1-144). A total of 208 pterygoid and 12 tuber implants failed, with a clear concentration of failures in the first year of follow-up and a 10-year CSR of 92.5% and 96.9%, respectively. The survival of pterygoid implants was lower than that of implants in the maxillary tuberosity (p = 0.006; log-rank test), and the survival of implants submitted to early/delayed loading was lower than that of immediately loaded implants (p < 0.001; log-rank test). Non-splinted implants presented higher failure rates. Few cases of intra- or postoperative complications were reported. Conclusions: Implants placed in the pterygoid process/maxillary tuberosity present a high 10-year CSR, although with lower survival for pterygoid in comparison to tuber implants. Pterygoid/tuber implants that are splinted with other implants may present higher survival rates than those that are not splinted.

Neoadjuvant chemoimmunotherapy was associated with better short-term survival of patients with locally advanced esophageal squamous cell carcinoma compared to neoadjuvant chemoradiotherapy.

The chemotherapy and immunotherapy combination is currently the primary strategy to treat metastatic esophageal squamous cell carcinoma (ESCC). Neoadjuvant chemoimmunotherapy (NCIT) is being intensively investigated for treating locally advanced ESCC. We compared the efficacy and safety of NCIT and neoadjuvant chemoradiotherapy (NCRT) to treat locally advanced ESCC. We included 214 locally advanced ESCC patients who were administered neoadjuvant therapy from May 2014 to April 2022. The patients were grouped according to two neoadjuvant protocols (NCIT and NCRT) routinely used at our institution. Perioperative findings, pathological results, and survival data were compared between the two groups by conducting unmatched and 1:1 propensity score matching (PSM) analyses. Following 1:1 PSM analysis of the confounders, 66 patients were allocated to each of the two groups. Time span between neoadjuvant therapy completion and esophagectomy was significantly longer after NCRT than that after NCIT (47.1 ± 13.2 days vs. 34.7 ± 8.8 days; p < 0.001). The NCIT group exhibited significantly greater number of harvested lymph nodes than the NCRT group (33.6 ± 12.7 vs. 21.7 ± 10.2; p < 0.001). The pathological complete response and major pathological response rates were similar between the two groups [NCIT group: 25.8% (17/66) and 62.1% (41/66), respectively; NCRT group: 27.3% (18/66) and 56.1% (37/66), respectively (p > 0.05)]. The overall incidence of pneumonia, anastomotic leakage, or postoperative complications did not differ significantly between the two groups. The 2-year cumulative overall survival rates and the 2-year disease-free survival rates of the NCIT and NCRT groups were 80.2% and 62.2%, respectively (p = 0.029) and 70.0% and 50.8%, respectively (p = 0.023). In locally advanced ESCC patients, short-term survival after NCIT is superior to that after NCRT, with similar perioperative and pathological outcomes.

Esthetically driven immediate provisionalization in the anterior zone: 5-year results from a prospective study evaluating 3.0-mm-diameter tapered implants

ObjectivesEvaluate the 5-year safety and efficacy of a narrow-diameter (3.0 mm) implant that was immediately provisionalized with a single crown in the maxillary lateral incisor or mandibular central or lateral incisor area.Materials and methodsAn open, prospective, single-cohort, multicenter study was conducted, in which narrow-diameter implants were placed in fresh, healed extraction, or congenitally missing sites. All patients were required to meet strict criteria for immediate loading. The primary endpoints were marginal bone levels (MBL) and MBL changes (MBLC) from implant placement to 5-year follow-up. Secondary endpoints included cumulative 5-year survival and success rates, soft tissue health, and esthetic parameters.ResultsA total of 91 implants were placed in 77 patients. The mean MBL remained stable from the 1-year (− 0.79 ± 0.73 mm, n = 75) to 5-year (− 0.74 ± 0.87 mm, n = 65) follow-up. A marginal bone gain of 0.11 ± 0.83 mm was observed from the 1-year to 5-year follow-up. The cumulative 5-year survival rate was 96.5%, and the cumulative 5-year success rate was 93%. The clinical parameters, including the modified plaque index, modified sulcus bleeding index, Jemt’s papilla index, and pink esthetic score improved throughout the 5-year study.ConclusionsThe study demonstrated that narrow-diameter implants represent a safe and predictable treatment option for subjects suitable for immediate loading and with limited bone volume or limited inter-dental space.Clinical relevanceNarrow-diameter implants with immediate provisionalization can be considered for use to restore missing or damaged teeth with predictable functional and esthetic outcomes. This trial was registered with ClinicalTrials.gov (NCT02184845).

Risk factors for distant metastasis and prognosis of the penile cancer with distant metastasis.

Penile cancer (PC) is a rare malignant tumor, whose distant metastasis (DM) is associated with the poorest outcomes. The risk factors associated with DM and prognosis of the PC with DM remain elusive. This study was aimed at investigating risk factors associated with DM and constructing prediction models of PC with DM. This study analyzed data from the Surveillance, Epidemiology, and End Results (SEER) database over a period of 2000-2020, including clinical characteristics such as age, marital status, tumor size, Tumor Node Metastasis (TNM) staging, and treatment information. Utilizing univariate and multivariate logistic regression, alongside cox regression analysis, we identified independent risk factors for DM and prognosis in the total cases and the cases with DM. Nomograms were developed for predicting DM and prognosis in PC patients. Enrolling 1,488 cases, our study identified tumor size and N stage as independent predictors of DM. The predictive nomogram for DM achieved an area under the curve (AUC) of 0.904. Notably, the 1-, 3-, and 5-year cumulative survival rates for PC with DM were 35%, 17%, and 13%, respectively, with larger tumor size associated with prognosis of PC cases with DM. This study verified a correlation between advanced age and TNM stage, as well as chemotherapy with the poor PC prognosis. The nomogram yielded 0.72, 0.69 and 0.69, in predicting 1-, 3-, and 5-year overall survivals (OS), while 0.73, 0.70 and 0.69 in predicting 1-, 3-, 5-year cancer specific survivals (CSS), respectively. This study investigated risk factors of PC with DM. Also, nomograms for predicting DM, OS and CSS of PC patients were developed.

Reoperative extended arch repair for acute type A aortic dissection after previous cardiac surgery: insights from a relatively young redo series.

To evaluate the impact of previous cardiac surgery (PCS) on clinical outcomes after reoperative extended arch repair for acute type A aortic dissection. This study included 37 acute type A aortic dissection patients with PCS (PCS group) and 992 without PCS (no-PCS group). Propensity score-matching yielded a subgroup of 36 pairs (1:1). In-hospital outcomes and mid-term survival were compared between the 2 groups. The PCS group was older (56.7 ± 14.2 vs 52.2 ± 12.6 years, P = 0.036) and underwent a longer cardiopulmonary bypass (median, 212 vs 183 min, P < 0.001) compared with the no-PCS group. Operative death occurred in 88 (8.6%) patients, exhibiting no significant difference between groups (13.5% vs 8.4%, P = 0.237). Major postoperative morbidity was observed in 431 (41.9%) patients, also showing no difference between groups (45.9% vs 41.7%, P = 0.615). Moreover, the multivariable logistic regression analysis revealed that PCS was not significantly associated with operative mortality (adjusted odds ratio 2.58, 95% confidence interval 0.91-7.29, P = 0.075) or major morbidity (adjusted odds ratio 1.92, 95% confidence interval 0.88-4.18, P = 0.101). The 3-year cumulative survival rates were 71.1% for the PCS group and 83.9% for the no-PCS group (log-rank P = 0.071). Additionally, Cox regression indicated that PCS was not significantly associated with midterm mortality (adjusted hazard ratio 1.40, 95% confidence interval 0.44-4.41, P = 0.566). After matching, no significant differences were found between groups in terms of operative mortality (P > 0.999), major morbidity (P > 0.999) and midterm survival (P = 0.564). No significant differences were found between acute type A aortic dissection patients with PCS and those without PCS regarding in-hospital outcomes and midterm survival after extended arch repair.

The effect of narrow band imaging in CO2 laser therapy in early-stage glottic cancer

Objective:To explore efficacy of narrow band imaging（NBI） technique in CO2laser therapy in Early-Stage Glottic cancer. Methods:The clinical data of patients with Early-Stage Glottic cancer who underwent CO2laser vocal cord resection from June 2011 to August 2022 were retrospectively analyzed. Among these, 27 patients who underwent surgery assisted by NBI were assigned to the observation group, while 25 patients who underwent conventional CO2 laser microsurgery with a suspension laryngoscope were assigned to the control group. The differences between the two groups were analyzed in terms of intraoperative frozen pathology results, postoperative recurrence rates, 5-year cumulative disease-free survival rates, complications, and voice recovery. Results:All 52 patients were operated successfully. Temporary tracheostomy and serious complications did not occur during the operation. The postoperative patient's pronunciation was satisfactory. One patient experienced vocal cord adhesion, but there were no severe complications such as breathing difficulties or bleeding, with an overall complication rate of 1.92%. Postoperative follow-up was 1-5 years. The 5 years recurrence free survival in the general group was 77.90％, and the 5 years recurrence free survival in the NBI group was 100％, the difference was statistically significant（P<0.05）. NBI endoscopy is safer and more accurate than the general group in determining the safe margin of tumor mucosal resection（P<0.05）. Among the patients who accepted the voice analysis, the difference was no statistically significant（P>0.05）. Conclusion:Compared with conventional CO2laser surgery under microscope, NBI guided laser resection of Early-Stage Glottic cancer is more accurate. NBI guided laser resection could improve 5 years recurrence free survival rate. In a word, narrow-band imaging endoscopy can has very high value in clinical application.

Mortality Risk Assessment Using the REVEAL 2.0 Score in Pulmonary Hypertension Secondary to Left Heart Disease.

Pulmonary hypertension (PH) frequently complicates the course of patients with left heart disease (PH-LHD) and is associated with worse clinical outcomes. Mortality calculators for PH-LHD are lacking, and it is unclear whether any risk prediction tools originally derived from other forms of PH can accurately predict outcomes in patients with PH-LHD. We retrospectively analyzed data from 161 patients diagnosed with PH-LHD referred to our pulmonary hypertension center from 2016 to 2022. We calculated the Registry to Evaluate Early and Long-Term PAH Disease Management (REVEAL 2.0) risk score and categorized patients as low, intermediate, or high-risk. We assessed survival at 1 and 3 years using Kaplan-Meier and Cox proportional hazards, as well as classification performance using a concordance index. At the first outpatient visit, 15% of patients were stratified as low-risk, 27% as intermediate, and 57% as high-risk. Cumulative 1-year survival rates were 100%, 94%, and 91% for the low, intermediate, and high-risk strata, respectively. Cumulative 3-year survival rates were 96%, 89%, and 70% for the low, intermediate, and high-risk strata, respectively. We found no difference in outcomes at 1 year between risk groups. High-risk patients had an increased risk of death at 3 years using REVEAL 2.0 (HR 5.32, p < 0.001). However, while REVEAL 2.0 accurately discriminated high-risk patients, the hazard ratio was not statistically different between patients classified as intermediate-risk compared to low-risk. REVEAL 2.0 accurately predicted 3-year survival in PH-LHD patients with high-risk features. However, the mortality risk between patients classified as intermediate-risk was not different from the low-risk stratum, suggesting inaccurate classification for this group of patients.

Risk factors and prognostic analysis of right ventricular dysfunction after lung resection for NSCLC.

Lung cancer is the leading cause of cancer death, and 80-85% of all lung cancer cases are non-small cell lung cancer (NSCLC). Surgical resection is the standard treatment for early-stage NSCLC. However, lung resection, a surgical procedure, can result in complications and increased mortality. Recent studies have shown a significant correlation between complications after lung resection and right ventricular dysfunction. Transthoracic echocardiography-derived right ventricular-pulmonary artery coupling (RV-PAC) was utilized to assess right ventricular function in these patients. Multivariate logistic regression analysis was also conducted to assess risk factors independently associated with RV-PA uncoupling. The 3- and 5-year cumulative survival rates were estimated with Kaplan-Meier curves, and differences between groups were analyzed using the Mantel-Cox log-rank test. RV-PA uncoupling was defined as a TAPSE/PASP value < 0.67 mm/mm Hg according to spline analysis. The results of multivariable logistic regression analysis indicated that diabetes is an independent risk factor for right ventricular dysfunction after lung resection in patients with NSCLC. Kaplan-Meier analysis revealed a significant decrease in the survival rate of patients with RV-PA uncoupling at both the 3-year follow-up (73% vs 40%, p < 0.001) and 5-year follow-up (64% vs 37%, p < 0.001). After lung resection for NSCLC, the patient's right ventricular function predicts prognosis. Patients with right ventricular dysfunction, particularly those with diabetes mellitus, have a worse prognosis. It is crucial to actively prevent and correct risk factors to reduce the mortality rate in these patients.
