ABSTRACT

BACKGROUND AND AIMS: Currently, there are no biomarkers with high accuracy in the detection of pancreatic cancer. This article aims to evaluate the performance of a novel diagnostic model based on a combination of biomarkers in the washing fluid obtained by EUS-FNA with imaging examination in pancreatic cancer.

METHODS: This study included 59 patients with pancreatic lesions who underwent EUS-FNA and were categorized into malignant and benign groups on the basis of pathology diagnosis. The levels of CEA, CA19-9, CA125, CA724, CYFRA 21-1, IMP3, SMAD4, and S100P in EUS-FNA washing fluid were detected by ELISA. We attempted to construct a new diagnostic method by combining the above biomarkers with EUS, CT, MRI, and PET-CT.

RESULTS: CEA, CA19-9, CA724, CA125, and CYFRA 21-1 showed statistical significance in the diagnosis of pancreatic cancer (AUC > 0.7, p < 0.05). CA724 had a specificity of up to 100% in the group with positive EUS diagnosis. If at least two positive imaging results (EUS/CT/MRI/PET-CT) combined with at least one tumor marker (CEA/CA199/CA724) in series, the sensitivity was 88.57% and the specificity was 91.67%.

CONCLUSIONS: Combining the tumor markers CEA, CA19-9, CA724, CA125, and CYFRA 21-1 in the washing fluid of EUS-FNA with commonly used imaging methods can help distinguish benign and malignant pancreatic lesions.

ABSTRACT

BACKGROUND: Research gaps persist in understanding the interactions between serum 25 (OH)D levels, intestinal fungi, and their metabolites in postmenopausal women.

METHODS: This study, approved by the Ethics Committee of Zhongshan Hospital, Xiamen University, recruited postmenopausal women from Xiamen. Clinical assessments included Body Mass Index (BMI) calculations and blood tests for various bone-related markers using Roche’s electrochemiluminescence system. Bone density was measured via dual-energy X-ray absorptiometry. Fecal DNA was extracted for Internal Transcribed Spacer (ITS) sequencing with a two-stage PCR process and analyzed using high-throughput Illumina sequencing. Metabolites were extracted from fecal samples and analyzed by ultra-high-performance liquid chromatography combined with mass spectrometry. Statistical analyses and data visualization were performed using R, focusing on fungal community structure and correlations with metabolites.

RESULTS: The study analyzed 81 postmenopausal women, categorized into vitamin D deficient (VDD), insufficient (VDI), and sufficient (VDS) groups based on serum 25 (OH)D levels. Other health markers, including age and BMI, were consistent across groups. Notably, Linear discriminant analysis identified distinct fungal communities across VDD, VDI, and VDS groups. In the VDD group, notable fungi included Hanseniaspora occidentalis and Pichia. The VDI group showed enrichment of Candida, while the VDS group had higher abundances Such as Phanerochaete, and Nectriaceae. Alpha diversity metrics, such as the Chao1 index, differed significantly among the groups (p < 0.05). Correlation analysis (Spearman) revealed that fungi like Trichosporon and Penicillium positively associated with 25 (OH)D3, whereas fungi such as Cystofilobasidium were negatively correlated with bone mineral density (BMD). Metabolites like Glutaric acid positively correlated with 25 (OH)D3, while L-Citrulline and Deoxycholic acid were negatively correlated. Additionally, Argininosuccinic acid correlated positively with BMD, whereas Acamprosate and p-Hydroxyphenylacetic acid were negatively associated.

CONCLUSION: In postmenopausal women, fungal community composition varies significantly with vitamin D status, potentially correlating with serum 25 (OH)D levels and BMD, indicating that specific fungal species may be relevant for therapeutic strategies with osteoporosis and offering insights into the broader bone health effects of vitamin D.

ABSTRACT

There are limited data on the impact of light sedation (LS) on changes in intraoperative hypotension related to carotid artery stenting (CAS). We aimed to investigate intraoperative hypotension and perioperative complications in CAS under LS with intravenous dexmedetomidine (Dex). A retrospective analysis of 140 consecutive patients who underwent CAS at our centre from September 2018 to March 2021 was performed. The primary endpoint was the incidence of intraoperative hypotension associated with CAS, defined as continuous systolic blood pressure < 90 mmHg. The secondary outcomes were perioperative complications, including dysphoria, transient ischaemic attacks (TIA), stroke, myocardial infarction (MI), reperfusion syndrome, and 24-h haemodynamic events after CAS. Eighty-nine patients were treated under LS, and 51 patients were treated under local anaesthesia (LA). Intraoperative haemodynamic instability was observed in 13 of 140 (9.3%) patients; hypotension occurred in 2.2% (2/89) of patients in the LS group, which was significantly lower than the rate in the LA group (2.2% vs. 11.8%, P = 0.027). Dysphoria occurred in 1.1% of the LS cohort and 15.7% of the LA cohort (P < 0.05). TIA was observed in 2.2% of the LS cohort and 15.7% of the LA cohort (P < 0.05), respectively. There were no statistically significant differences in periprocedural stroke, reperfusion syndrome, or 24-h haemodynamic events after CAS between the two groups, and none of the patients exhibited MI. Performing CAS under LS with intravenous Dex was a safe and effective anaesthesia option in terms of inhibiting intraoperative hypotension and could markedly decrease the incidence of dysphoria and TIA.

ABSTRACT

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely detected in water and sediment worldwide. Despite growing concerns about their ecological and health risks, their distribution in African aquatic environments remains understudied. This study addresses the knowledge gap in PFAS contamination by analysing the spatial and temporal distribution of 18 PFAS in Apies River water and sediment in Pretoria, South Africa. Surface water and sediment samples were collected upstream and downstream of the Apies River during dry seasons. The analysis of PFAS concentrations was conducted using liquid chromatography-tandem mass spectrometry. Statistical analysis, including paired t-tests, non-metric multidimensional scaling, and hierarchical cluster analysis, were applied to determine spatial and temporal trends. The study revealed significant spatial variations in PFAS contamination, with upstream locations consistently exhibiting higher concentrations than downstream. In surface water samples, L_PFBS, 4:2 FTS, 6:2 FTS, and L_PFHpS showed statistically significant differences (p < 0.05) between sites. Perfluorocarboxylic acids were the dominant PFAS class in surface water (50.47-57.15%), whereas perfluorosulfonic acids were more prevalent in sediments. Upstream sediment had higher L_PFHpS (43.00 ng/g), L_PFDS (38.89 ng/g), and L_PFHxS (23.91 ng/g) than downstream (31.96, 27.84, and 18.02 ng/g, respectively). The findings reveal contamination sources and partitioning between surface water and sediments, aiding in water quality management and pollution mitigation strategies.

ABSTRACT

BACKGROUND: As a joint project with the Ministry of Health, Labour and Welfare (MHLW), the Research Group on Intractable Renal Diseases is examining the feasibility of utilizing its personal clinical records database. We examine the validity of the initial-treatment data from the personal clinical records of patients with new-onset rapidly progressive glomerulonephritis (RPGN).

METHODS: Personal clinical records for patients with either RPGN or anti-glomerular basement membrane (GBM) antibody nephritis were used. The data from 454 newly enrolled RPGN patients were compiled for analysis in 2 cohort studies (CS1 for all case analysis and CS2 for selective analysis of new-onset cases).

RESULTS: In CS1, the serotypes of the 362 registered RPGN cases included 200 myeloperoxidase (MPO)-ANCA-positive, 98 anti-GBM-positive, and 9 proteinase-3 (PR3)-ANCA-positive cases, etc. CS2 included 96 of the MPO-ANCA-positive RPGN and 55 of the anti-GBM antibody-positive RPGN cases. For the initial treatment of MPO-ANCA-positive RPGN, the rates of glucocorticoid (GC) and GC pulse treatment were similar between the personal clinical records database and the nationwide questionnaire survey, but the rates of intravenous cyclophosphamide (CY) or rituximab were statistically significant lower in the personal clinical records database. For the initial treatment of anti-GBM antibody-positive RPGN, the rate of plasma exchange was similar between the two databases, but the rates of GC and per os CY tended to be lower in the personal clinical records database, although not statistically significant.

CONCLUSION: Clear differences in initial treatment for new-onset RPGN patients were found between a personal clinical records database and another reported database.

ABSTRACT

INTRODUCTION: This study presents clinical und functional long-term outcomes up to 10 years after primary total hip arthroplasty (THA) without concomitant surgical intervention and a far proximal cup positioning.

METHODS: 33 patients (44 hips) underwent primary THA for severe dysplastic hip osteoarthritis with a far proximal cup position. Hips were divided into two groups: Group A (n = 27) with cups positioned at 55-65 mm and Group B (n = 17) with cups positioned > 65 mm from the interteardrop line. Functional outcomes were assessed at 114 ± 15 months postoperatively using LEFS, HHS, HOOS, and Tegner Activity Score. Patient satisfaction and leg length difference were also evaluated. Statistical analysis employed the Mann-Whitney U test (p < 0.05 significance level).

RESULTS: The study found no significant differences in the two groups in terms of functional results, as measured by HOOS (89.1 ± 12.1 vs. 89.0 ± 8.3; p = 0.5145), LEFS (66.7 ± 13.1 vs. 68.7 ± 11.5; p = 0.5544), and HHS (95.1 ± 7.4 vs. 94.9 ± 4.4; p = 0.2707). Both groups showed very good functional results. The Tegner Activity Score significantly improved in both groups from preoperative to final follow-up (A: 2.1 ± 1.4 to 4.0 ± 0.7; p = 0.0002; B: 1.8 ± 1.1 to 3.9 ± 1.1; p = 0.0009). There were no significant differences found when comparing the pre- and postoperative leg length differences (p = 0.5793). No complications including dislocation events, impingement or neurological complications were observed. Furthermore, no patient required revision surgery.

CONCLUSION: Primary total hip arthroplasty with far proximal, non-anatomic socket positions is a safe and effective treatment option with excellent functional long-term results in severe dysplastic hip osteoarthritis.

ABSTRACT

This study aimed to explore the potential causal relationships between rosacea and Parkinson’s disease, Alzheimer’s disease, anxiety disorders, and depression with MR analysis. Genetic data for rosacea and the four neurodegenerative and neuropsychiatric disorders were sourced from GWAS databases. After completing stringent quality control procedures, SNPs meeting significance thresholds were selected as IVs. Our primary statistical analysis was conducted by IVW approach. To investigate the robustness of results, heterogeneity tests, sensitivity analyses, and pleiotropy assessments were conducted. Reverse MR analyses were subsequently carried out to further substantiate the causal relationships. The present study discovered a positive correlation between rosacea and an elevated risk of depression (OR = 1.0015, 95% CI = 1.0002-1.0027, P = 0.02). There is no causal evidence to support a connection between rosacea and Parkinson’s disease, Alzheimer’s disease, or anxiety disorders. Reverse MR analyses indicated no causal associations between these four disorders and the risk of rosacea. The findings reveal that individuals with rosacea may have an elevated risk of depression.

ABSTRACT

Onychomycosis is a highly prevalent disease that causes great morbidity. Topical and oral treatment are not always effective and can be associated with side effects. Energy-based devices have been studied as a safe therapeutic tool. 36 cases received 4 to 8 laser treatments with 1 or 2-week-interval. Patients were reevaluated after 1, 3, 6 and 12 months and the Onychomycosis Severity Index (OSI) was calculated each visite. 69,4% showed an improvement in the OSI, with 12 (33.3%) progressing to cure and 13 (36,1%) showing a decrease in the global score. There was a statistically significant reduction in the median OSI over time, especially at 6-month and 12-month assessments (p = 0.022 and p < 0.001, respectively). Five or more treatments were associated to a better outcome (p = 0.001). On the other hand, there was no interference regarding gender, age, presence of more than 1 affected nail or pathogen isolated in culture. A positive outcome was statistically more relevant in patients who were classified as severe before treatment (p = 0.015). Furthermore, cases that presented dermatophytoma had a more favorable outcome, with 78.5% improvement after 12-months follow-up (p = 0.040). All patients tolerated well the sessions even if pain was present and they were all satisfied with their results. No adverse events were detected. Nd: YAG laser can effectively treat onychomycosis and the outcome is even better in cases that present with dermatophytoma, suggesting that this laser could be used as a form of debridement, increasing cure rates, especially when associated with systemic medication.

ABSTRACT

Background: The International Trauma Questionnaire (ITQ) is a validated measure supporting the diagnosis of ICD-11 post-traumatic stress disorder (PTSD) and complex PTSD (cPTSD). It has been translated into 35 languages, also into Polish. Due to the lack of information in the literature about its validation, new Polish version has been re-adapted and validated in the Polish non-clinical and clinical samples of the present study.Objective: The study aimed (1) to adapt the ITQ for use in Polish, (2) to assess the construct validity of ICD-11 PTSD and cPTSD in the Polish ITQ, and (3) to examine the convergent and discriminant validity of the Polish ITQ.Method: The study sample comprised of 452 adults: a non-clinical sample, N = 314, (completed the online version of the questionnaire) and a clinical sample, N = 138, (used a pen-and-paper version). Confirmatory Factor Analysis (CFA) and Latent Class Analysis (LCA) were performed to assess the structure of the ITQ.Results: The CFA supported a two-factor second-order model as the best fit to the data. All factor loadings were statistically significant and reached a satisfactory level. Cronbach’s alpha for ITQ (α = 0.887), PTSD (α = 0.810) and DSO (α = 0.875) were good. The LPA revealed four classes: (1) a cPTSD class with elevated PTSD and DSO symptoms; (2) a PTSD class with elevated PTSD symptoms but low scores on the DSO; (3) a DSO class with elevated DSO symptoms but low scores on the PTSD; and (4) a low symptom class with low scores on all symptoms.Conclusion: The amended Polish ITQ has good internal consistency and psychometric properties. The model is well fitted to differentiating PTSD/cPTSD diagnoses according to ICD-11 and is a reliable measure of support for the making of a PTSD/cPTSD diagnosis in the conduct of clinical interview.

ABSTRACT

BACKGROUND: Hormonal, metabolic, and immunologic factors may cause several skin changes during pregnancy. Therefore, it is important for pregnant women to be aware of these expected changes in their skin appearance in order to prevent unwanted effects and to choose the appropriate preventive or treatment measures via trustable sources of information.

OBJECTIVE: This study would highlight the most common normal and abnormal physiological skin changes mothers usually complain about before or after pregnancy. The most commonly used skin care products, their sources of knowledge, information, perception, and experiences on these problems and products were also considered. In addition, patient satisfaction levels and their sources and types of knowledge were also investigated.

METHODS: Across sectional survey was distributed among women who met the inclusion criteria and were citizens in the Hashimate Kingdom of Jordan. This survey was composed of a number of questions used for investigating participant’s socio-demographic characteristics, during and post-pregnancy characteristics and medications used, comparison of skin related complains reported by these women, in addition to their use of skin care products. Women’s knowledge, perception, and experience regarding their use of skin care products were also included.

RESULTS: Of the 337 participants in this study, 6.5% and 6.8% of women were using thyroid medications and antihypertensive agents. An increase of around 3% in pregnancy-related skin changes, such as hyperpigmentation, hair loss, cellulite, and wrinkles, was predominant among women. Despite the prevalence of hyperpigmentation, only 4% and 17% of women used depigmentation and sunblock products. Moreover, women declare that their information about the use of skin care products was mainly via social media or self-experience. A low rate of consultation with dermatologists and the reliance on self-diagnosis or non-professional advice were shown.

CONCLUSION: This study suggests a lack of awareness about effective preventive measures for skin-related disorders commonly occurring during pregnancy, potentially exacerbated by reliance on unverified sources of information, such as social media. Therefore, incorporating education about skin changes into routine prenatal care could empower women to make informed decisions and reduce the stigma associated with these changes.
