RÉSUMÉ
Introduction: Early prediction and intervention are crucial for the prognosis of unexplained recurrent spontaneous abortion (uRSA). The main purpose of this study is to establish a risk prediction model for uRSA based on routine pre-pregnancy tests, in order to provide clinical physicians with indications of whether the patients are at high risk. Methods: This was a retrospective study conducted at the Prenatal Diagnosis Center of Henan Provincial People's Hospital between January 2019 and December 2022. Twelve routine pre-pregnancy tests and four basic personal information characteristics were collected. Pre-pregnancy tests include thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine thyroid (FT4), thyroxine (TT4), total triiodothyronine (TT3), peroxidase antibody (TPO-Ab), thyroid globulin antibody (TG-Ab), 25-hydroxyvitamin D [25-(OH) D], ferritin (Ferr), Homocysteine (Hcy), vitamin B12 (VitB12), folic acid (FA). Basic personal information characteristics include age, body mass index (BMI), smoking history and drinking history. Logistic regression analysis was used to establish a risk prediction model, and receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were employed to evaluate the performance of prediction model. Results: A total of 140 patients in uRSA group and 152 women in the control group were randomly split into a training set (n = 186) and a testing set (n = 106). Chi-square test results for each single characteristic indicated that, FT3 (p = 0.018), FT4 (p = 0.048), 25-(OH) D (p = 0.013) and FA (p = 0.044) were closely related to RSA. TG-Ab and TPO-Ab were also important characteristics according to clinical experience, so we established a risk prediction model for RSA based on the above six characteristics using logistic regression analysis. The prediction accuracy of the model on the testing set was 74.53%, and the area under ROC curve was 0.710. DCA curve indicated that the model had good clinical value. Conclusion: Pre-pregnancy tests such as FT3, FT4, TG-Ab, 25-(OH)D and FA were closely related to uRSA. This study successfully established a risk prediction model for RSA based on routine pre-pregnancy tests.

Fingertip injuries, particularly those resulting from motorbike chain accidents, pose significant challenges due to their impact on daily life activities. This retrospective study conducted at B&B Hospital in Kathmandu from January 2018 to December 2022 aimed to explore the epidemiology and management of motorbike chain-related fingertip injuries. Among the 256 cases of fingertip injuries studied, 136 were attributed to motorbike chain accidents. Males comprised the majority of cases, and the index and middle fingers were the most frequently injured. Various surgical procedures were employed for treatment, with V-Y Plasty being the most common. These findings underscore the complexity of managing these injuries and highlight the importance of preventive measures and patient-centered care.

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 < 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 < 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 < 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 < 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 < 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.

Objectives: We aimed to evaluate the drug utilization of Ginkgo biloba extract (Gbe), systemic corticosteroids (CSs), and pentoxifylline (PTXF) for the treatment of acute tinnitus by analyzing electronic patient health record data. In addition, we assessed whether the different drug treatments were associated with different frequencies of repeat visits to ear, nose, and throat (ENT) doctors. Methods: This retrospective cohort study used data from the IQVIA Disease Analyzer (DA) database. It included patients with an initial diagnosis of tinnitus between January 2005 and December 2021, treated by ENT specialists in Germany. Results: Of 111,629 patients meeting all selection criteria, 51,205 received prescriptions of Gbe, 34,817 of systemic CSs, and 25,607 of PTXF. Gbe prescription was associated with significantly lower odds of a repeat consultation due to tinnitus compared to systemic CSs [odds ratio (OR) 0.91; 95% confidence interval (CI): 0.88-0.95] as well as PTXF (OR 0.74; 95% CI: 0.72-0.77). This association was significant in both men and women and in some age groups. Conclusion: Gbe is the most frequently ENT specialist-prescribed drug for the treatment of acute tinnitus. It is associated with a reduced likelihood of patients consulting their ENT specialist for tinnitus again compared to systemic CSs and PTXF.

OBJECTIVE: Serum lipoprotein(a) [Lp(a)] is a risk factor of cardiovascular diseases. However, the relationship between the serum Lp(a) and clinical outcomes has been seldom studied in Chinese hospitalized patients with cardiovascular diseases. METHODS: We retrospectively collected the clinical data of hospitalized patients with cardiovascular diseases in the Cardiovascular Department of Dongguan People's Hospital from 2016 to 2021 through the electronic case system. Patients were divided into 4 groups based on Lp(a) quartiles: Quartile1 (≤ 80.00 mg/L), Quartile 2 (80.01 ~ 160.90 mg/L), Quartile 3 (160.91 ~ 336.41 mg/L), Quartile 4 (> 336.41 mg/L). Cox proportional hazard regression models were constructed to examine the relationship between Lp(a) and cardiovascular events. RESULTS: A total of 8382 patients were included in this study. After an average follow-up of 619 (320 to 1061) days, 1361 (16.2%) patients developed major adverse cardiovascular events, and 125 (1.5%) all-cause death were collected. The incidence of MACEs was 7.65, 8.24, 9.73 and 10.75 per 100 person-years in each Lp(a) quartile, respectively; the all-cause mortality was 0.48, 0.69, 0.64 and 1.18 per 100 person-years in each Lp(a) quartile, respectively. The multivariate Cox regression analysis suggested that high Lp(a) level was an independent risk factor for MACEs (HR: 1.189, [95% CI: 1.045 to 1.353], P = 0.030) and all-cause death (HR: 1.573, [95% CI: 1.009 to 2.452], P = 0.046). CONCLUSION: In addition to traditional lipid indicators, higher Lp(a) exhibited higher risks of adverse cardiovascular events and death, indicated worse prognosis. Lp(a) may be a new target for the prevention of atherosclerotic diseases.

BACKGROUND: Large type 3 (diameter ≥ 8 cm) and type 4 gastric cancers have been arbitrarily combined in Japan as a single entity. However, whether these two types are oncologically similar remain unclear. This study aimed to clarify this issue. METHODS: In this retrospective study, we analyzed a database of 3,575 patients from nine institutions who underwent gastrectomy between 2010 and 2014. Using propensity scores to balance significant variables, we compared prognoses and tumor recurrences. RESULTS: Of patients with clinical T3/T4 who underwent R0 resection, 75 and 73 had large type 3 and 4 tumors, respectively. Patients with type 4 tumors had significantly lower overall survival rates than those of patients with large type 3 tumors (hazard ratio [HR] 1.77; 95% confidence interval [CI] 1.14-2.74). However, among the large type 3 tumors, a remarkable difference in prognosis was observed between the differentiated and undifferentiated histological types. A comparison was made between large type 3 with undifferentiated phenotype and type 4, each with 39 patients after propensity score matching. Outcomes in both groups were similar in terms of overall survival (HR 1.28; 95% CI 0.73-2.25) and relapse-free survival (HR 1.34; 95% CI 0.80-2.27). No statistically significant differences were observed in the incidence of peritoneal recurrence (35.9% vs. 46.1%, P = 0.36) and lymph node recurrence (25.6% vs. 12.8%, P = 0.15). CONCLUSIONS: Large type 3 tumors with undifferentiated phenotype and type 4 tumors were oncologically similar. This subgroup could be considered as a new entity for future clinical trials.
RÉSUMÉ
BACKGROUND: Canine leishmaniosis (CanL), caused by Leishmania infantum, is an important vector-borne parasitic disease in dogs with implications for human health. Despite advancements, managing CanL remains challenging due to its complexity, especially in chronic, relapsing cases. Mathematical modeling has emerged as a powerful tool in various medical fields, but its application in understanding CanL relapses remains unexplored. METHODS: This retrospective study aimed to investigate risk factors associated with disease relapse in a cohort of dogs naturally infected with L. infantum. Data from 291 repeated measures of 54 dogs meeting the inclusion criteria were included. Two logistic mixed-effects models were created to identify clinicopathological variables associated with an increased risk of clinical relapses requiring a leishmanicidal treatment in CanL. A backward elimination approach was employed, starting with a full model comprising all potential predictors. Variables were iteratively eliminated on the basis of their impact on the model, considering both statistical significance and model complexity. All analyses were conducted using R software, primarily employing the lme4 package, and applying a significance level of 5% (P < 0.05). RESULTS: This study identified clinicopathological variables associated with an increased risk of relapses requiring a leishmanicidal treatment. Model 1 revealed that for each 0.1 increase in the albumin/globulin ratio (A/G) ratio, the odds of requiring treatment decreased by 45%. Conversely, for each unit increase in the total clinical score (CS), the odds of requiring treatment increase by 22-30%. Indirect immunofluorescence antibody test (IFAT) was not a significant risk factor in model 1. Model 2, incorporating individual albumin and globulins values, showed that dogs with high IFAT titers, hyper beta-globulinemia, hypoalbuminemia, anemia, and high CS were at increased risk of relapse. Both models demonstrated a good fit and explained a substantial amount of variability in treatment decisions. CONCLUSIONS: Dogs exhibiting higher CS, dysproteinemia, anemia, and high IFAT titers are at increased risk of requiring leishmanicidal treatment upon clinical relapse in CanL. Regular monitoring and assessment of risk factors prove essential for early detection of relapses and effective intervention in CanL cases. The contrasting findings between the two models highlight the complexity of aspects influencing treatment decisions in this disease and the importance of tailored management strategies to improve outcomes for affected dogs.

Background: The evidence on the association of fine particulate matter with an aerodynamic diameter of 2.5 µm or less (PM2.5) with pulmonary tuberculosis (PTB) retreatment is limited. There are no data on whether greenness exposure protects air pollution-related PTB retreatment in patients with prior PTB. Objective: In a population-based retrospective study, we aimed to investigate the influence of PM2.5 and residential greenness on the risk of PTB retreatment. Methods: A total of 26,482 patients with incident PTB, registered in a mandatory web-based reporting system between 2012 and 2019 in Zhengzhou, China, were included in the analysis. The exposure to PM2.5 was assessed based on the China High Air Pollutants dataset, and the level of greenness was estimated using the Normalized Difference Vegetation Index (NDVI) values. The associations of PTB retreatment with exposure to PM2.5 and greenness were evaluated, respectively, considering the local socioeconomic level indicated by the nighttime light index. Results: Among the 26,482 patients (mean age 46.86, SD 19.52 years) with a median follow-up time of 1523 days per patient, 1542 (5.82%) PTB retreatments were observed between 2012 and 2019. Exposure to PM2.5 was observed to be significantly associated with the increased risk of PTB retreatment in fully adjusted models with a hazard ratio of 1.97 (95% CI 1.34-2.83) per 10 µg/m3 increase in PM2.5. Patients living in the regions with relatively high quartiles of NDVI values had a 45% lower risk of PTB retreatment than those living in the regions with the lowest quartile for the 500 m buffers (hazard ratio 0.55, 95% CI 0.40-0.77). Such a protective effect of residential greenness was more pronounced among patients living in lower nighttime light areas. The strength of the association between PM2.5 exposure and the risk of PTB retreatment was attenuated by greenness. No significant association was observed between NDVI and the incidence of drug resistance. Conclusions: Long-term exposure to PM2.5 might be a risk factor for PTB retreatment, while an increased level of residential greenness was found to be associated with reduced risks of PTB retreatment. Our results suggest strengthening the control of ambient air pollution and improving residential greenness may contribute to the reduction of PTB retreatment.

OBJECTIVE: This study aimed to assess clinical efficacy of 4-mm-short implants in patients with posterior severe vertical bone atrophy in the medium- and long-term follow-up. MATERIALS AND METHODS: Patients rehabilitated with 4-mm-short implants in the posterior atrophic jaws, with a minimum follow-up of 3 years post-loading, were included in the study. Data were collected for eligible patients, and marginal bone loss (MBL) for each implant was evaluated. The research outcomes were implant failure, MBL and complications. RESULTS: A total of 212 patients with 496 implants were included, resulting in a mean follow-up of 8.02 ± 2.17 years. The implant survival rate was 95.36% (95% CI: 93.12%-97.04%). More implant failures were observed in the maxilla (p = .02) and fewer failures were observed in patients undergoing more number of hygienic sessions per year (p < .001). The average MBL after 1-year-loading was 0.47 mm, increasing to 0.59 mm after 10 years; after 3 years no statistically significant increase in MBL was observed. Maxillary implants showed greater bone loss than mandibular ones (p < .001). More frequent professional oral hygiene sessions per year resulted being related with reduced MBL (p < .001). CONCLUSIONS: Four-mm-short implants showed high survival rates with an up to 10-year follow-up. Their use can offer a fixed prosthetic solution for patients with posterior vertical bone atrophy, minimizing surgical invasiveness, rehabilitative times and costs.
RÉSUMÉ
OBJECTIVES: The aim of this retrospective study was to compare the clinical results of two root canal sealers and three obturation techniques used for non-surgical root canal treatment. MATERIALS AND METHODS: A total of two hundred eighty-three root canal treated teeth in two hundred thirty-seven patients with minimum a 6-month follow-up was included for this study. The canals were filled with three different modes: 1) cold lateral condensation (CLC) and AH Plus Sealer; 2) continuous wave condensation technique (CWC) and AH Plus Sealer, and 3) sealer-based obturation technique (SBO) and AH Plus Bioceramic Sealer. The treatment outcome was analysed based on clinical signs and symptoms, and periapical radiograph (periapical index, PAI). RESULTS: There were no significant differences in treatment outcome between various sealers and filling techniques applied. The sealer extrusion was found most frequently in the CWC group (60.67%), followed by SBO (59.21%) and CLC (21.19%) with statistically significant differences (p < .05). The initial diagnosis, previous treatment and sealer extrusion (p < .05) were prognostic factors that affected treatment outcome. CONCLUSIONS: Based on the findings of this study, neither the sealer type nor the filling technique affected the treatment success while preoperative diagnosis, previous treatment and sealer extrusion had significant effect on the outcome. CLINICAL RELEVANCE: A bioceramic sealant applied along with the single-cone technique might be considered as an alternative method in root canal obturation.

INTRODUCTION: This study reported on the outcome of the nonsurgical root canal treatment/retreatment of teeth with large apical periodontitis lesions. The influence of some variables on the prognosis was also evaluated. METHODS: The study included 199 teeth with large apical periodontitis lesions from 184 patients, treated/retreated bya single operator. Most teeth were managed in a single visit using NaOCl irrigation. Cases were followed up periodically from >1 to 8 years. Treatment/retreatment outcome was evaluated by clinical and radiographic/tomographic criteria and categorized as healed, healing, or diseased. For statistical analysis, data were dichotomized in such a way that healing cases were considered as success in a loose criterion or failure in a rigid one. RESULTS: Clinical/radiographic analyses revealed that 67% of the initial treatment cases were classified as healed, 22.5% as healing, and 11% as diseased. Treatment success rates were 89% (loose) and 67% (rigid). Variables that influenced the treatment outcome included previous abscess and antibiotic use, very large lesions (> 10 mm), and a sinus tract. The median follow-up time for treatment was 31.5 months. As for retreatment cases, 47% were healed, 32% were healing, and 21% were diseased. Retreatment success rates were 79% (loose) and 47% (rigid), in a median follow-up of 32 months. Cases evaluated by cone-beam computed tomography had higher failure rates. CONCLUSIONS: Findings demonstrate that high favorable outcome rates can be achieved by nonsurgical root canal treatment or retreatment of teeth with large apical periodontitis lesions.

Purpose: To evaluate the real-world clinical and safety outcomes of a 0.19 mg fluocinolone acetonide intravitreal implant to treat diabetic macular edema (DME). Methods: This retrospective analysis comprised patients treated with a single fluocinolone acetonide intravitreal implant for the clinical indication of ME secondary to diabetic retinopathy. Primary outcomes included changes in best-corrected visual acuity (BCVA), central subfield thickness (CST), and the frequency of DME-related treatments 12 months before and up to 36 months after fluocinolone acetonide administration. Safety outcomes were also assessed. Results: One hundred forty-eight eyes (115 patients) were followed for a mean (±SD) of 12.3 ± 4.2 months before and 29.4 ± 14.5 months after fluocinolone acetonide administration. A 0.8-letter decrease (Early Treatment Diabetic Retinopathy Study) in the mean BCVA was observed at month 24. The BCVA was 70 letters (20/40 Snellen equivalent) or more in 20.6% of eyes at baseline and in 23.7% of eyes 24 months after implant administration. The mean CST was 379.9 µm and 323.7 µm, respectively. The CST was 300 µm or less in 58.7% of eyes at month 24 (P < .001). The mean frequency of intravitreal antivascular endothelial growth factor injections or laser photocoagulation decreased from 4.9 to 1.5 per year after fluocinolone acetonide administration (P < .001). Implant migration to the anterior chamber occurred in 3 eyes, 2 of which were vitrectomized and later required removal. Conclusions: The 0.19 mg fluocinolone acetonide intravitreal implant provided long-term stabilization of VA and macular anatomy in patients with DME, despite a significant reduction in treatment frequency.
RÉSUMÉ
PURPOSE: To compare short-term outcomes between membrane perforation and non-perforation patients after simultaneous external elevation with implantation. MATERIALS AND METHODS: In this retrospective observational study, 60 maxillary posterior tooth-loss patients with an insufficient amount of residual bone for direct implantation were enrolled. All patients underwent simultaneous external elevation and implantation, and were divided into perforation and non-perforation groups according to the postoperative Schneiderian membrane status. RESULTS: Of the 60 patients, 30 cases (35 implants) were assigned to the membrane perforation group, and 30 (44 implants) were allocated to the non-perforation group. There were no statistically significant differences in baseline data (p>0.05). In the perforation group, the mean vertical bone gain (VBG) at 6 and 12 months was 6.02±2.14 mm and 5.37±2.22 mm, resp., compared to 6.78±2.59 mm and 6.42±2.64 mm in the non-perforation group, resp. (both p>0.05). Preoperative median Schneiderian membrane thickness (SMT) in the perforation group was 0.77 mm, which was statistically significantly thinner than the 1.24 mm measure in the non-perforation group (p< 0.05); however, there was no statistically significant difference between two groups at 12 months postoperatively (0.80 mm vs 1.25 mm, p>0.05). The marginal bone loss at 1 year after implant restoration in the perforation and non-perforation groups was 0.16±0.10 mm and 0.22±0.12 mm, resp. During postoperative follow-up, the implant survival rate was 100% in the two groups. The incidence of postoperative nasal bleeding in the perforation group was statistically significantly higher compared with that in the non-perforation group (50% vs 16.7%, p<0.05), whereas no statistically significant differences were observed in the incidence of facial swelling, intraoral bleeding, wound dehiscence and acute/chronic sinusitis between the two groups (p>0.05). CONCLUSIONS: Schneiderian membrane perforation after simultaneous external elevation and implantation do not adversely affect short-term clinical and radiographic outcomes.

BACKGROUND: The association between serological indexes and occurrence of complications in patients with autoimmune gastritis (AIG) remains unclear. METHODS: 91 patients with AIG were recruited and their clinical information were collected. The differences between serological indexes and complications of AIG were analyzed. And potential biomarker for early prediction and diagnosis of AIG with complications was explored. RESULTS: AIG patients in our study was 58.12±11.68 years old, containing 31 males and 60 females. G17 was elevated in 49 of 52; PGI/II decreased in 43/49; GPA positive in 48/61; Anemia presented 28 in 80; Vitamin B12 deficiency occurred 23 in 58. Neuroendocrine tumor (NET) was the most common complication in AIG patients, accounting for 27/91. The second was polyps, making up for 14/91. There is also 9/91 of gastric mucosa neoplasia happened in AIG. No significant difference of G7, PGI, PGII, PGI/II and VB12 in AIG was found in different gastric mucosal lesions (P > 0.05). However, AIG patients with TPOAb positive had a higher risk in the occurrence of NET simultaneously (Pâ¯=â¯0.0212). Those AIG with NET patients exhibited a significantly higher TPOAb level (Pâ¯=â¯0.0078). ROC curve suggested that TPOAb can predict the existence of NET in AIG (AUCâ¯=â¯0.7410, P < 0.05). CONCLUSION: We found that TPOAb can serve as a predictive biomarker of NET in AIG. This accessible test is helpful for endoscopy specialists to pay attention to gastric mucosal lesions in TPOAb-positive AIG patients, improving early diagnosis and intervention of comorbidities ability.

AIM: Peritonitis is the most common complication of peritoneal dialysis (PD). This study aimed to investigate changes in the incidence, risk factors, microbiology, and clinical outcomes of PD-associated peritonitis in the past decades. METHODS: This was a retrospective study that included children who initiated chronic PD at our institution between 2000 and 2017. The patients were divided into two groups according to the year of initiation: those who initiated PD between 2000 and 2008 and those who initiated PD between 2009 and 2017. The incidence and characteristics of peritonitis were compared between the groups. RESULTS: A total of 184 patients with a median age of 10.2 years were included in this study. Of the patients, 92 experienced 210 episodes of peritonitis. The incidence rate of peritonitis decreased from 0.35 to 0.21 episodes/patient year during the study period (P = 0.001). During the 2000-2008 period, the 2-year peritonitis-free survival rate was significantly lower for patients under 2 years of age than for the other age groups (P = 0.004), whereas this was not observed during the 2009-2017 period. The multivariable Cox proportional hazard model showed that the <2 years age group had a significantly higher risk of developing peritonitis in the 2000-2008 period. However, this was not evident in the 2009-2017 period. CONCLUSIONS: The incidence of PD-associated peritonitis decreased, particularly in children under 2 years of age. Thus, younger age may not be a risk factor for PD-associated peritonitis.

OBJECTIVES: The objective of this long-term retrospective study was to evaluate the fracture rate and the risk factors associated with the fracture of 3.3 mm narrow diameter implants (NDIs). MATERIALS AND METHODS: A total of 524 records of patients rehabilitated with 3.3 mm NDIs between 1997 and 2015 were assessed. Data on patients, implants, and prostheses were collected, and descriptive analysis of the variables was performed. NDIs were separated into 2 groups: "fractured" and "non-fractured", and a multilevel logistic regression model was applied to identify the risk factors associated with NDI fracture. RESULTS: Eighty-four patients were removed from the analysis for interrupting follow-up or presenting failures other than fractures. Of the 440 patients included (64.66 ± 13.4 years), 272 were females (61.8%), and 168 males (38.2%), and mean follow-up time was 129 ± 47.1 months. Of the 1428 NDIs, 15 (1.05%) in 9 patients (2.04%) fractured during the studied period. Ten fractures (66.66%) happened in 6 patients (66.66%) showing signs of parafunction. NDI with modified sandblasted, large grit, acid-etched surface was the only implant variable to show a protective statistical significance (p = .0439). CONCLUSIONS: NDI fracture was a rare event in the studied sample. NDIs manufactured with modified sandblasted, large grit, acid-etched surface may provide extra protection against NDI fracture. Patient-specific factors and implant characteristics should be carefully considered to limit the risk of fracture of 3.3 mm NDIs.

STUDY DESIGN: Retrospective cohort analysis. OBJECTIVE: CCS is the most common type of incomplete spinal cord injury and can occur without or with bony injury. Surgical intervention and its timing for patients diagnosed with CCS has been controversial. The current study assessed utilization of and factors associated with operative intervention and its timing in patients diagnosed with central cord syndrome (CCS) in the absence of bony injury. METHODS: Adult patients diagnosed with CCS in the absence of vertebral fracture were queried from the national, multi-insurance, administrative 2015-2020 M151 PearlDiver database. The incidence, trends, and timing of operative intervention following CCS were assessed. Patient characteristics associated with surgical intervention and its timing were determined. RESULTS: From 2015 to 2020, 11,653 patients meeting inclusion criteria were identified, of which surgical intervention was identified for 2,003 (17.2%) and thus nonsurgical intervention for 9,650 (82.8%). The proportion of patients undergoing operative intervention evolved from 11.5% in 2015 to 19.7% in 2020 (p < 0.0001). Of those undergoing surgical intervention, the greatest increase was seen for those undergoing surgery within two days of diagnosis (5.5% in 2015 to 12.3% in 2020, p < 0.0001). On multivariable analysis, more recent year of service, region of service, younger age, and higher comorbidity burden were independent predictors of operative management (p < 0.05 for all). CONCLUSION: The majority of a large cohort of patients with first diagnosis CCS in the absence of bony injury were managed non-operatively. Operative management increased over the years of study, were performed earlier after diagnosis, and varied based on patient characteristic and geographic region.

BACKGROUND: Studies on oral health status of adults are sparse and rarely include data on endodontic treatment and trauma. In the military, those data are available because recruits are routinely assessed with a clinical and radiological examination at the start of their career. This study aimed to identify differences in oral health status of Dutch Armed Forces recruits between cohorts, departments, sex, age and rank, with DMF-T, endodontic treatment and dental trauma as outcome measures. METHODS: Data from Electronic Patient Files from all recruits enlisted in 2000, 2010 and 2020 were used for analysis in a hurdle model resulting in the estimated cohort effect, controlled for the demographic variables. The total number of recruits was 5,764. Due to the retrospective character of the study a proxy was used to compose D-T and dental trauma. RESULTS: The mean DMF-T number in recruits decreases from 5.3 in cohort 2000 to 4.13 in cohort 2010 and 3.41 in cohort 2020. The percentage of endodontically treated teeth increases from 6% in cohort 2000 to respectively 9% in 2010 and 8% in 2020. The percentage of recruits showing signs of dental trauma did not change significantly between cohort 2000 (3.1%) and cohort 2010 and 2020 (both 2.7%). CONCLUSIONS: Oral health in Armed Forces recruits is improving over the years, following a similar trend as the general population in the Netherlands. Lower SES represented by enlisted rank showed substantial lower oral health status.

Background: Depression has been suggested to increase the risk of cardiovascular disease, but many studies assessed depression after heart disease onset. This study evaluated the association between depression and myocardial infarction (MI) using a large inpatient database.Methods: We analyzed patients from the National Inpatient Sample hospitals from 2005 to 2020, selecting those aged >30 with ICD-9 and ICD-10 codes for segment elevation (ST) elevation myocardial infarction (STEMI), non-ST elevation myocardial elevation (NSTEMI) and major depression.Results: Our data included 4413,113 STEMI patients (224,430 with depression) and 10,421,346 NSTEMI patients (437,058 with depression). No significant association was found between depression and MI. For STEMI, the 2005 odds ratio was 0.12 (95% CI: 0.10-0.15, p < 0.001) and the 2020 odds ratio was 0.71 (95% CI: 0.69-0.73, p < 0.001). Similar patterns were observed for NSTEMI.Conclusion: Depression may not independently be a significant risk factor for MI.
Depression has been suggested to increase the risk of cardiovascular disease, but many studies assessed depression after heart disease onset. This study evaluated the association between depression and myocardial infarction (MI) using a large inpatient database. We analyzed patients from the National Inpatient Sample hospitals from 2005 to 2020, selecting those aged greater than 30. No significant association was found between depression and MI. Depression may not independently be a significant risk factor for MI. Our results suggest that patients with anxiety or depression have no association with the occurrence of MI.We suspect that the observed results may be related to the effects of selective serotonin reuptake inhibitors on platelets. Selective serotonin reuptake inhibitors primarily increase serotonin levels in the brain by inhibiting its reuptake. However, they can also affect platelet function by inhibiting serotonin reuptake by platelets. This inhibition of serotonin reuptake by platelets can lead to decreased platelet aggregation, which may confer some level of protection against certain conditions involving platelet dysfunction or excessive clotting. This effect is particularly relevant in cardiovascular diseases where abnormal platelet function can contribute to thrombotic events like heart attacks or strokes.
