ABSTRACT

BACKGROUND: Allergic rhinitis (AR) and asthma due to house dust mite (HDM) are increasing in children worldwide, including Indonesia, where the tropical environment favors HDM proliferation. Although Subcutaneous immunotherapy (SCIT) is widely used, local pediatric evidence remains limited.

OBJECTIVE: To evaluate the effect of HDM SCIT on clinical and immunological outcomes in children with AR and AR plus asthma.

METHODS: A double-blind randomized controlled trial was conducted in 41 children, divided into AR (n=20) and AR+asthma (n=21) groups. Participants received weekly HDM SCIT for 14 weeks. Total IgE, specific IgE, IL-10, TGF-β1, Combined Symptom Medication Score (CSMS), and Visual Analogue Scale (VAS) were measured before and after treatment. Statistical analyses included paired t-test, Wilcoxon, independent t-test, and Mann-Whitney, with significance at p<0.05.

RESULTS: HDM SCIT significantly reduced total IgE, TGF-β1, CSMS, and VAS (p<0.05). Specific IgE showed a downward trend without statistical significance. IL-10 levels slightly increased but were not significant (p=0.683). No significant differences in treatment effect were observed between AR and AR+asthma groups (p>0.05).

CONCLUSION: HDM SCIT improved clinical outcomes and reduced key immunological markers in children with AR and AR plus asthma, though no intergroup differences were found. These findings provide preliminary evidence supporting HDM SCIT as a safe and beneficial adjunct therapy in Indonesian pediatric populations.

ABSTRACT

Introduction Seborrheic keratoses (SK) are common benign epidermal tumors. Their pathogenesis is unknown, and no pathological significance is ascribed to them, although they could be part of paraneoplastic syndromes, in addition to presenting a variety of somatic mutations. SKs are associated with increased age, family history and sun-exposure. Methods This study aimed to analyze if SK was related to DNA repair genes polymorphisms and analyze if any epidemiological, clinical or environmental characteristics could modify their prevalence. It was conducted an epidemiological, analytical, observational, cross-sectional, retrospective case-control study. Both univariate and multivariate logistic regression models were used to evaluate which characteristics were associated with having >50 SKs versus <10. Results A total of 294 patients with melanoma were studied, 270 (91.8%) having had less than 10 SKs, while 24 (8.2%) >50. Of all the polymorphisms studied, only rs25487 in XRCC1 reached statistical significance (OR=3.56; 95% CI 1.36-9.33; p=0.01). In addition, an increasing age (OR=1.07; 95% CI 1.03-1.11; p=0.001) and the phototype (III-V vs. I-II) (OR=0.28; 95% CI 0.12-0.68; P=0.005) were related to the presence of >50 SKs. Conclusion We identified that increasing age, having a phototype I-II and the existence of the rs25487 polymorphism could be associated with the occurrence of KS.

ABSTRACT

OBJECTIVE: This study aims to evaluate the effect of serum cholinesterase (CHE) levels on early neurological deterioration (END) in patients with mild anterior circulation stroke.

METHODS: We conducted a retrospective case-control study in the Neurology Department of Jiangsu Taizhou People’s Hospital from July 2018 to June 2023. A total of 334 patients with mild anterior circulation ischemic stroke (National Institutes of Health Stroke Scale [NIHSS] ≤5 points) admitted within 24 h were included. Patients were classified into an END group and a non-END group according to the occurrence of END, and binary logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) across serum CHE quintiles.

RESULTS: A statistically significant difference and a clear linear trend (p < 0.05) were identified after adjusting for multiple confounding factors, indicating a protective effect of elevated CHE levels against END. Age stratified analysis was limited by reduced sample sizes and insufficient statistical power to detect potential subgroup differences.

CONCLUSION: In this retrospective case-control study, the END group had a significantly higher incidence of atrial fibrillation (AF) and lower CHE levels than the non-END group. The findings indicate an inverse association between CHE levels and the risk of END.

ABSTRACT

BACKGROUND: The COVID-19 pandemic prompted a rapid expansion of telehealth services in patients with substance use disorders (SUD) and comorbid mental health conditions (dual diagnosis). However, evidence on the effectiveness and utilization of hybrid care (combining in-person and telehealth modalities) in this population remains limited.

OBJECTIVE: This study aims to analyze the use of a hybrid treatment (telehealth and in-person treatment) among patients with dual pathology across three distinct periods-before, during, and after COVID-19-related public health measures-and to assess the impact of hybrid care on treatment dropout rates.

METHODS: A retrospective observational study was conducted using electronic health records (EHR) from 6,365 outpatients diagnosed with SUD and comorbid mental disorders, between March 2018 and September 2023. Patients were classified by treatment modality (in-person vs. hybrid) and period of care. Bivariate statistics and Cox regression analyses were performed to identify predictors of treatment dropout, accounting for demographic and clinical variables.

RESULTS: Hybrid care utilization increased significantly during the pandemic and remained elevated post-pandemic. Women and patients with opioid use disorder were more likely to receive hybrid care. Patients receiving hybrid therapy had significantly lower dropout rates and longer treatment durations. Also, patients in coordinated care (addiction and mental health centers) show lower rates of dropout. Cox regression confirmed that hybrid care was the strongest predictor of reduced treatment dropout across all periods.

CONCLUSIONS: Hybrid care models enhance treatment retention among dual diagnosis patients, underscoring the need to maintain and optimize telehealth options for this high-risk group even beyond pandemic-related restrictions.

ABSTRACT

BACKGROUND: Metastatic bladder urothelial carcinoma has poor survival, and large comparative genomic studies using uniform targeted sequencing of paired primary and metastatic lesions remain limited. We compared gene- and pathway-level alterations between primary and metastatic tumors METHODS: We analyzed 2,880 bladder urothelial carcinoma samples (2,305 primary; 575 metastatic) from 2,343 patients profiled with MSK-IMPACT. Somatic mutations and copy number alterations were integrated per gene and compared between primary and metastatic samples in the full cohort and in a paired subset using standard statistical tests.

RESULTS: Primary and metastatic samples showed broadly similar driver landscapes. In the full cohort, KDM6A, FGFR3, STAG2, and ERCC2 were more frequently altered in primary tumors, whereas no individual genes were enriched in metastases; these differences were not significant in paired analyses. At the pathway level, TP53 pathway alterations were relatively more frequent in metastases, while DNA damage response alterations were enriched in primary tumors; other pathways showed comparable alteration rates. Apoptosis-focused analyses identified no significant gene-level differences, but suggested a trend toward higher alteration rates in the TP53 pathway and apoptosis regulators in metastases.

CONCLUSION: Primary and metastatic lesions of bladder urothelial carcinoma show broadly similar gene- and pathway-level alteration profiles on targeted DNA sequencing. TP53 pathway and apoptosis-related alterations are modestly more frequent in metastases, consistent with impaired stress responses and apoptosis evasion.

ABSTRACT

BACKGROUND: The 9th edition of the UICC TNM classification redefined N categories and clinical stages for salivary gland cancer (SGC). We validated the prognostic utility of this redefinition and evaluated the impact of anatomical nodal spread.

METHODS: We retrospectively analyzed 166 patients with SGC and 93 parotid gland cancer (PGC) patients treated with curative surgery. Cases were restaged according to the TNM classification of the UICC 9th edition. Kaplan-Meier survival curves, Cox models, and statistical indices (AIC, likelihood ratio χ², C-index) were used to compare the findings based on the 8th and 9th editions. Nodal metastases were classified as “Intraparotid lymph nodes (LNs) only”, “Limited to levels I-III LNs”, and “Beyond levels I-III LNs”.

RESULTS: Kaplan-Meier curves showed clearer separation by N category and clinical stage for the 9th edition, although its prognostic performance by statistical indices was similar to that of the 8th edition. In the PGC surgery subset, LN metastasis, particularly N2 in the 9th edition, was the strongest adverse prognostic factor, and the new 9th edition pathological N categories were also useful. Additionally, prognosis worsened with increasing nodal extent. Twelve patients with metastases beyond levels I-III developed distant metastases despite standard treatment, and 10 with salivary duct carcinoma, indicating potential benefit from adjuvant systemic therapy.

CONCLUSIONS: Kaplan-Meier analyses suggested that the 9th edition provided better intercategory discrimination than the 8th edition, despite no statistical superiority being demonstrated. Nodal metastasis extending beyond levels I-III may be a useful biomarker for selecting patients for adjuvant systemic therapy.

ABSTRACT

Climate change is rapidly altering high-latitude coastal wetlands through increasing temperatures, more frequent flooding, and changing herbivore abundance and distribution. Examining plant functional trait responses to these drivers provides insight into how plant communities are shaped by climate change. We used a one-year full-factorial mesocosm experiment in coastal Alaska to assess immediate responses of two size-related traits (vegetative height and leaf area) and two leaf economics traits (specific leaf area [SLA] and leaf dry matter content [LDMC]) to warming, flooding, and goose herbivory in three dominant species across two wetland communities (Lowland and Upland) differing in landscape position. We sampled different sedges (Carex rariflora and Carex lyngbyei) and the same deciduous dwarf-shrub (Salix fuscescens) in the two wetlands. Warming increased plant size for the sedge (leaf area: + 15%) and the shrub (height: + 15%; leaf area: + 19%) in the Lowland wetland only. Flooding promoted acquisitive trait values for the Lowland sedge (SLA: + 8%; LDMC: – 6%) and conservative values for the Upland shrub (SLA: – 9%; LDMC: + 11%). The shrub thus showed clear wetland-specific responses to warming and flooding. Herbivory triggered coordinated responses across all three species, consistently decreasing size-related trait values (height: – 17-35%; leaf area: – 33-50%) and promoting acquisitive trait values (SLA: + 14-40%; LDMC: – 12-23%). Despite the absence of interactions, each driver contributed significantly to trait variation, underscoring the value of multifactorial approaches. The combination of consistent (herbivory) and context-dependent (flooding and warming) responses highlights the complexity of trait responses and improves predictions of rapid phenotypic adjustments in coastal high-latitude wetlands.

ABSTRACT

Value-Based Healthcare (VBHC) is gaining traction in civilian systems, but its relevance and feasibility for Military Health Systems (MHSs) in Central and Eastern Europe (CEE) remain unclear. This pilot study explored familiarity, perceived applicability and desirability of VBHC among military healthcare stakeholders. A pilot cross-sectional perception study was conducted during the 2024 VIMIMED Military Medicine Conference, combining a brief expert introduction with a structured survey. The survey assessed baseline familiarity, perceived applicability in home-base and operational care, and desirability of VBHC implementation. Descriptive statistics were used. The association between familiarity and desirability was explored using Fisher’s exact test. Among 65 workshop participants, 37 completed the survey. Over half of respondents reported low baseline familiarity with VBHC (51.4%). Despite this, VBHC was widely perceived as desirable (89.1%). No statistically significant association was found between familiarity and desirability (Fisher’s exact test, P = .672). Thirty-five respondents considered VBHC applicable in at least one domain and were included in component-level analyses. The components “multidisciplinary team,” “educate, innovate & improve,” and “IT & data” were most frequently endorsed as applicable. Respondents who perceived VBHC as applicable in both home-base and operational care tended to endorse more components than those who perceived applicability in home-base care only. Despite limited baseline familiarity, VBHC was widely perceived as desirable and contextually applicable within CEE MHSs. These exploratory findings suggest potential for targeted, phased integration of selected VBHC components. Larger and, more representative studies are needed to assess implementation feasibility, pathways, and sustainability of VBHC in MHSs.
