ABSTRACT

CONTEXT: Oxidative stress is an important factor for vitreomacular interface disease development in a theoretical model.

PURPOSE: The aim of the study was to evaluate the correlation between oxidative stress in the human epiretinal membrane (ERM) and retinal morphological changes.

MATERIAL AND METHODS: The study included patients scheduled for vitrectomy with epiretinal membrane removal. LogMAR best corrected visual acuity was assessed and optical coherence tomography was performed. Patients were divided into three groups: Type 1 – epiretinal membrane with premacular fibrosis; type 2 – epiretinal membrane with co-existing layer hole; and type 3 – ERM with co-existing full-thickness macular hole. During vitrectomy, epiretinal membranes were collected. Total oxidant status was determined by an automated colorimetric method in homogenates of epiretinal membrane.

STATISTICAL ANALYSIS: The Mann-Whitney U test, Kruskal-Wallis test and Spearman linear correlation analysis were used. Statistical significance was set with a level of α = 0.05.

RESULTS: Twenty-one Caucasian women (60%) and 14 men (40%) were included in the study. The average age of participants was 74.7 years (95% CI: 71.13-75.45). The mean best corrected visual acuity LogMAR value in the group was 0.8 (95% CI: 0.9-0.7). The mean ratio of total oxidant status to protein level in the collected samples was 0.161 (95% CI: 0.08-0.23) µmol/mg of protein. No correlation was found between total oxidant status and the degree of morphological retinal changes.

CONCLUSION: The study found no significant correlation between the level of oxidative stress in epiretinal membrane and retinal morphological changes.

ABSTRACT

Despite grey matter atrophy in cortical and subcortical regions has been related to cognitive impairment in multiple sclerosis, only a few studies evaluated its predictive value for alterations in the long-term. We aimed to determine early predictors of cognitive status after 20 years of multiple sclerosis. In this longitudinal retrospective study, participants underwent a 1.5 T MRI scanning at diagnosis (T0) and after two years (T2), which included the evaluation of regional grey matter volume loss patterns. All individuals with multiple sclerosis underwent a comprehensive neuropsychological assessment at the end of the study and were classified considering their global and specific cognitive domains status (memory, attention/information processing speed, executive functioning). Clinical and MRI characteristics were assessed as predictors of long-term cognitive impairment. Analysis of covariance, t-test, unadjusted and adjusted (for age, sex, disease duration, volume of white matter lesions, volume of cortical lesions) logistic regression were conducted. One hundred seventy-five people with multiple sclerosis (118 females; mean ± SD age at the end of study = 47.7 ± 9.4 years) clinically followed for 20 years from onset (mean ± SD = 19.9 ± 5.1) were evaluated. At the end of the study, 81 (47%) were classified as cognitively impaired: 38 as mildly impaired (22%), and 43 as severely impaired (25%). In particular, 46 were impaired in memory (27%), 66 were impaired in attention/information processing speed (38%), and 71 were impaired in executive functioning (41%). Regression models identified precuneus (adjusted odds ratio = 3.37; P < 0.001), insula (adjusted odds ratio = 2.33; P = 0.036), parahippocampal gyrus (adjusted odds ratio = 2.07; P < 0.001) and cingulate (adjusted odds ratio = 1.81; P = 0.009) as the most associated regions with global cognitive impairment and domains-specific cognitive alterations after a mean of 20 years of multiple sclerosis, after adjusting for demographic and clinical variables as well as for focal white matter and grey matter damage. Early grey matter volume loss of specific cortical and deep grey matter regions predicts global and domain cognitive alterations after 20 years from multiple sclerosis diagnosis.

ABSTRACT

PURPOSE: To explore the relationship between hyperlipidemia and full-frequency idiopathic sudden sensorineural hearing loss (FFHL).

PATIENTS AND METHODS: A total of 145 FFHL patients admitted from September 2021 to May 2024 were analyzed. Eighty-five patients with hyperlipidemia and 60 patients with normal serum lipids statistically analyze the patient’s gender, age, onset time, accompanying symptoms, and serum lipids. Measure the pure tone hearing threshold before and after treatment, and calculate the average increase in hearing threshold. Compare the correlation between various factors and prognosis.

RESULTS: The hyperlipidemia group had a higher proportion of males (P=0.043) and vertigo (P=0.044) compared to the control group, while other information between the two groups lacked statistical significance. Effective patients (n=44) in the hyperlipidemia group showed significant differences in vertigo (P=0.020), age (P=0.032), and onset (P=0.030) compared to ineffective patients (n=41). Analysis showed that these were independent correlated factors affecting prognosis. Other indicators, including serum lipids, have no significance in predicting the prognosis of patients with hyperlipidemia and complete frequency decline in hearing loss.

CONCLUSION: Patients with hyperlipidemia have higher rates of males and vertigo. The age, onset, and vertigo of patients with hyperlipidemia are related to prognosis, while various lipid indicators are not related to the prognosis of sudden hearing loss.

ABSTRACT

BACKGROUND: The inflammatory response is the main pathophysiological basis of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and is a key factor leading to frequent exacerbations and disease progression. Suppressing the inflammatory response can improve pulmonary function, prognosis, and quality of life in AECOPD patients.

PURPOSE: To evaluate the effect of Qingjin Huatan decoction (QHD) on pulmonary function and inflammatory mediators in AECOPD patients.

METHODS: Randomized controlled trials (RCTs) on the treatment of AECOPD with QHD were retrieved from eight Chinese and English electronic databases up to 31 May 2024. The quality of the studies was assessed using the Cochrane Risk of Bias Tool and the modified Jadad scale. Statistical analysis, sensitivity analysis, and publication bias assessment were performed using Stata 17.0 software.

RESULTS: A total of 40 RCTs involving 3,475 AECOPD patients were included. Compared to conventional treatment, QHD significantly improved pulmonary function, with increases in FEV1 (MD = 0.30, 95% CI: 0.26 to 0.34, p = 0.000), FVC (MD = 0.34, 95% CI: 0.27 to 0.41, p = 0.000), FEV1/FVC (MD = 6.07, 95% CI: 5.55 to 6.58, p = 0.000), and PaO₂ (MD = 7.20, 95% CI: 4.94 to 9.47, p = 0.000), and a decrease in PaCO₂ (MD = -5.37, 95% CI: 7.99 to -2.74, p = 0.000). QHD also significantly suppressed the expression of inflammatory mediators, including TNF-α (MD = -10.87, 95% CI: 12.51 to -9.23, p = 0.000), IL-1β (MD = -13.63, 95% CI: -16.31 to -10.95, p = 0.000), IL-6 (MD = -7.58, 95% CI: -10.10 to -5.06, p = 0.000), IL-8 (MD = -9.45, 95% CI: -12.05 to -6.85, p = 0.000), CRP (MD = -5.62, 95% CI: -6.60 to -4.65, p = 0.000), and PCT (MD = -0.84, 95% CI: -1.07 to -0.62, p = 0.000). Additionally, QHD improved clinical efficacy (RR = 4.16, 95% CI: 3.26 to 5.30, p = 0.000) without increasing the incidence of adverse reactions (RR = 1.04, 95% CI: 0.68 to 1.61, p = 0.000).

CONCLUSION: Existing evidence suggests that QHD can significantly improve pulmonary function, suppress the expression of inflammatory mediators, and enhance clinical efficacy in AECOPD patients, with a good safety profile. Given the limitations of this study, more high-quality studies are needed to provide reliable evidence.

ABSTRACT

PURPOSE: Child abuse and trauma are significant risk factors in the etiology of borderline personality disorder (BPD). Apart from affecting the risk of developing BPD, adverse childhood experiences seem to increase its symptoms and related disability. Self-stigma presents another common issue with equally prominent consequences for mental health. Despite being theoretically linked, the connections among childhood trauma, self-stigma, and mental health have not been explored in patients with BPD. This study aimed to provide first insights into this understudied topic.

PATIENTS AND METHODS: This cross-sectional study included 283 inpatients diagnosed with BPD participating in a residential transdiagnostic psychotherapeutic program. The patients completed several measurements – the Internalized Stigma of Mental Illness Scale, the Childhood Trauma Questionnaire – Short Form, the Clinical Global Impression – Severity, the Beck Depression Inventory-II, the Beck Anxiety Inventory, the Dissociative Experiences Scale, the Sheehan Disability Scale, and a demographic questionnaire. The data was statistically analyzed using IBM SPSS and AMOS 26 programs, and bivariate correlation tests and structural equation modeling explored the hypotheses.

RESULTS: Retrospectively reported childhood trauma positively correlated with current self-stigma. Both childhood trauma and self-stigma were also positively related to several indicators of general psychopathology and disability. The significance of these connections was subsequently confirmed by structural equation modeling, where self-stigma acted as a partial mediator of childhood trauma, general psychopathology, and disability.

CONCLUSION: Self-stigma significantly mediates the relationship between childhood trauma and selected mental health symptoms among adult patients diagnosed with BPD. Longitudinal studies are necessary to explore the causality of the findings. Therapeutic and societal efforts to tackle childhood trauma or self-stigma might benefit from reflecting its broader psychosocial context.

ABSTRACT

Purpose: Medication-related osteonecrosis of the jaw (MRONJ) caused by bisphosphonates (BPs) and denosumab (Dmab) is still a major oral adverse event caused by cancer treatment and may be under-recognized by private dental services. With the aim of reducing the prevalence of MRONJ, this study, which is a pilot study for a planned future large-scale survey, compared knowledge about MRONJ between dental hygienists (DHs) in private dental clinics and those in cancer center hospitals. Methods: We conducted a questionnaire-based survey regarding MRONJ between 1 November 2023 and 31 January 2024 on DHs at a cancer base hospital and a private clinic in Saitama, Japan. We statistically analyzed the data collected using the χ² test or Fisher’s exact test with the level of significance set at 5%. Results: This study included 10 in-hospital and 53 private clinic DHs. The in-hospital DHs had appropriate knowledge of MRONJ. However, compared with the in-hospital DHs, although the private clinic DHs knew that BPs are used for osteoporosis, significantly fewer had knowledge of Dmab (p < .001) or knew that BPs and Dmab could also be used to treat cancer (both p < .001). In addition, few private clinic DHs were aware of MRONJ cases refractory to antibiotic treatment alone (p = .012). Conclusion: These findings suggest that private clinic DHs have less knowledge of MRONJ than those in cancer base hospitals.

ABSTRACT

BACKGROUND/AIM: Current evidence indicates a correlation between the inflammatory potential of diet and the risk of cancer and cancer-specific mortality. This study aimed to assess the association between empirical dietary inflammatory pattern (EDIP), which has recently been designed based on the inflammatory potential of the diet, and the risk of cancer and cancer-specific mortality.

METHODS: A systematic literature search was conducted across the PubMed/Medline, Scopus, and Web of Science databases from January 2016 to March 2024. A random effects model was used to calculate the pooled effect size (ES) and 95% confidence intervals (95% CI). Heterogeneity between studies was assessed using the Cochran Q test and the I ² statistic.

RESULTS: From the initial 229 records, 24 prospective cohort studies with 2,683,350 participants and 37,091 cancer incidence cases, as well as 20,819 cancer-specific mortality, were included in our study. Pooled results indicated a significant association between higher adherence to the EDIP and an increased risk of total cancer (ES: 1.10; 95% CI: 1.05-1.15; I ² = 41.1), colorectal cancer (ES: 1.19; 95% CI: 1.11-1.27; I ² = 41.1), and liver cancer (ES: 1.48; 95% CI: 1.14-1.94; I ² = 36.9). However, no significant association between increased adherence to the EDIP and an increased risk of ovarian or endometrial cancer was found. Furthermore, greater adherence to the EDIP was significantly associated with an increased risk of cancer-specific mortality (ES: 1.18; 95% CI: 1.05-1.33; I ² = 45.4).

CONCLUSION: Our results showed that a diet with higher inflammatory properties is associated with an increased risk of cancer and cancer-specific mortality.

ABSTRACT

This study aimed to optimize the culture conditions of the termite-derived fungus Aspergillus chevalieri BYST01 for the production of physcion, a characteristic component of the traditional herb rhubarb, which has been commercially approved as a botanical fungicide in China. First, potato dextrose broth was screened as the suitable basal medium for further optimization, with an initial yield of 28.0 mg/L. Then, the suitable carbon source, fermentation time, temperature, pH value, and the rotary shaker speed for physcion production were determined using the one-variable-at-a-time method. Based on the results of single factors experiments, the variables with statistically significant effects on physcion production were further confirmed using the Plackett-Burman design (PBD). Among the five variables, temperature, initial pH, and rotary shaker speed were identified as significant factors (P < 0.05) for physcion productivity in the PDB and were further analyzed by response surface methodology (RSM). Finally, we found that the maximum physcion production (82.0 mg/L) was achieved under the following optimized conditions:initial pH 6.6, rotary shaker speed of 177 rpm, temperature of 28 °C, and glucose concentration of 30 g/L in PDB medium after 11 d of fermentation. The yield of physcion under the optimized culture conditions was approximately threefold higher than that obtained using the basal culture medium. Furthermore, the optimum fermentation conditions in the 5-L bioreactor achieved a maximal physcion yield of 85.2 mg/L within 8 d of fermentation. Hence, response surface methodology proved to be a powerful tool for optimizing physcion production by A. chevalieri BYST01. This study may be helpful in promoting the application of physcion produced by A. chevalieri BYST01 to manage plant diseases.

ABSTRACT

BACKGROUND: Tennis, the second-largest ball game in the world, has a particularly wide audience. To date, little research has been conducted on the biomechanics of female serves.

PURPOSE: The purpose of this study was to capture the key moments by using 1,000 frames/s high-speed video analysis, to analyze the kinematics of the serving techniques of national athletes and provincial athletes, to determine the differences between the two levels of athletes, and to provide theoretical references for the improvement of scientific training level.

METHODS: Ten female athletes were selected as participants for this study, five of whom are national athletes, and the other are provincial athletes. Three-dimensional filming techniques were employed to capture videos of the first and second serve techniques. Simi Motion was applied to obtain the 3D kinematic data. Statistical analyses were performed using IBM SPSS Statistics 27.0, and Mann-Whitney U tests were conducted to determine differences between groups.

RESULTS: Significant differences in kinematics were found between national and provincial athletes. At the moment of the left knee’s minimum flexion (T2), in the first serve, national athletes had a smaller shoulder-hip vertical plane angle (-18.281 ± 6.142° vs. -25.631 ± 3.497°; p = 0.047) and a larger hip vertical plane rotation angle (-9.378 ± 4.263° vs. -0.470 ± 4.724°; p = 0.047). In the second serve, national athletes had a smaller hip horizontal plane rotation angle (-1.720 ± 4.683° vs. 24.146 ± 24.014°; p = 0.047) but a larger hip vertical plane rotation angle (-11.553 ± 1.949° vs. -0.422 ± 4.958°; p = 0.009). At the moment of impact (T4), in the second serve, national athletes’ batting position (0.296 ± 0.088 m vs. 0.446 ± 0.094 m; p = 0.047) was further back. Additionally, in the second serve, national athletes consistently had their body center of gravity further back at T2 (-0.106 ± 0.052 m vs. -0.018 ± 0.048 m; p = 0.028), T3 (0.002 ± 0.038 m vs. 0.132 ± 0.039 m; p = 0.009), and T4 (0.073 ± 0.050 m vs. 0.217 ± 0.034 m; p = 0.009).

CONCLUSIONS: The results of this study indicated several significant kinematic differences between national and provincial athletes, these variations were noted in the shoulder, hip, and body center of gravity. In summary, for the overall first and second serves, it is recommended that national athletes increase the horizontal plane angle of the shoulders and hips at T2, whereas provincial athletes decrease the horizontal plane angle of the shoulder-hip. In addition, provincial athletes need to increase the vertical plane angle of the hip joint, so that the top of the hip can be increased more, and provincial athletes need to be careful not to have the center of gravity too far in front of the body at T2, T3, and T4, so that it can hit the ball at a higher position to increase the swing speed.

ABSTRACT

Curative surgery for localized prostate cancer can lead to iatrogenic erectile dysfunction (ED), affecting couples. Sexuality remains influenced by social norms, often requiring men to provide pleasure through rigid erections. However, iatrogenic ED does not prevent male orgasm, although it can disrupt body image and self-esteem. This study aims to describe couples’ sexual repertoire and partners’ sexual satisfaction post radical prostatectomy at the Centre Hospitalier Universitaire de Martinique. A monocentric retrospective observational study was conducted with data collected from January 2021 to March 2024. The Valentin and ASEX questionnaires were administered to the partners of future vesiculo-prostatectomy patients at the start of the sex-rehabilitation program. Responses were analyzed anonymously using the Sphinx iQ2 application. The characteristics of the population were described in terms of proportions and means, with a significance threshold set at 0.05 for statistical tests.Of the 152 couples identified, 65 Valentine questionnaires were available. Respondents were heterosexual women, with an average age of 59, and their partners had an average age of 64. Non-penetrative sex was already part of the sexual repertoire for 52% of couples prior to prostate cancer diagnosis. After surgery, 32% of partners resumed penetrative sex, while 43% had not yet resumed sexual intimacy, and 14% had resumed non-penetrative sex. Mutual fondling (85%), vaginal penetration (70%), female oro-genital sex (70%) and male oro-genital sex (52%) were the most popular sexual stimuli. Surgery was therefore no obstacle to sexual satisfaction for our respondents, with a satisfaction level of 90% before and 86% after total prostatectomy. The same applies to orgasm before and after total prostatectomy.The results show that erectile dysfunction is not an obstacle to partners’ sexual satisfaction, with couples able to reinvent their sexuality around non-penetrative practices. Sexual satisfaction indicators before and after RA show a strong correlation, confirming that surgery does not negatively affect sexual satisfaction. The results show that men suffering from post-RP ED can free themselves from the dogma of penile erection by exploring female sexual pleasure to a greater extent. Couples practicing non-penetrative sexuality report satisfying, more playful, complicit and varied sexuality. Finally, ED has less of an impact on partners than future operators believe.
