Human papillomavirus (HPV) infection is the primary cause of cervical, anogenital, and oropharyngeal cancers in the United States. These cancers are preventable through HPV vaccination. Research is critically needed to identify effective strategies for promoting HPV vaccination among high-risk groups. This study develops a risk prediction model to identify patients who are unlikely to complete HPV vaccination, with the goal of using the model to direct resources and increase vaccination rates.

We assessed vaccination status along with patient, provider, and clinic characteristics that predict vaccination completion. We then developed a predictive model to assess the likelihood of completing HPV vaccination, which can be used to target interventions based on patient needs. We used a retrospective cohort from a large integrated delivery system in Oregon. Using logistic regression with data available in the electronic health record, we created a risk model to determine the likelihood of vaccination completion among patients aged 11–17 years.

In a cohort of 61,788 patients, 40,570 (65.7%) had received at least one dose of the HPV vaccine. The full model included 17 demographic, clinical, provider, and community characteristics, achieving a bootstrap-corrected C-statistic of 0.67 with adequate calibration. The reduced model, which retained five demographic and clinical characteristics (age, language, race, ethnicity, and prior vaccinations), had a bootstrap-corrected C-statistic of 0.65 and adequate calibration.

Our findings suggest that a risk prediction model can guide the implementation of targeted interventions and the intensity of those interventions based on the likelihood of vaccination completion.

Sepsis involves a complex cascade of inflammatory reactions and immune system dysregulation. Neutrophils play a crucial role in modulating the anti-inflammatory response, which is vital for managing sepsis. Impaired chemotaxis of granulocytes can significantly impact the outcome of sepsis. Shenfu Decoction, by tonifying Qi and warming Yang, enhances the propelling function of Qi for promoting the chemotactic function of neutrophils. This study aimed to investigate the effects of Shenfu Decoction on the chemotactic function of neutrophils in septic mice and the underlying mechanisms.

Thirty 10-week-old specific-pathogen-free male C57BL/6J mice were randomly divided into five groups: sham operation, model, and low-, medium-, and high-dose Shenfu Decoction treatment groups (n = 6 in each group). Sepsis was induced using cecum ligation and puncture procedures. The sham-operated group served as the control. The drug was administered 6 h after surgery; the sham-operated and model groups received saline, while the treatment groups were gavaged every 12 h with the respective concentrations of Shenfu Decoction. Four hours after the last gavage, the mice were euthanized, and samples were collected to determine neutrophil counts and related indices. Primary neutrophils were extracted from the peripheral blood of septic mice and divided into blank control, sham-operated, low-dose, and high-dose groups. These cells were cultured with serum containing the respective treatments to measure neutrophil chemotactic distance, intracellular calcium ion concentration, and the expression levels of chemokine receptors and P2X1 receptors.

Compared with the sham-operated group, the total number of colonies and the number of neutrophils in the peritoneal lavage fluid were increased in the model group (P < 0.05). In the treatment groups, the number of neutrophils in the peritoneal lavage fluid was significantly increased (P < 0.05), while the number of neutrophils in the blood was decreased. Compared with the blank control group, the neutrophil chemotaxis distance was significantly prolonged in the sham-operated group. Additionally, the expression levels of P2X1 and FPR1 receptors were decreased, the expression levels of CXCR1 and CXCR2 receptors were increased (P < 0.05), and the calcium ion concentration was decreased (P > 0.05). Compared with the sham-operated group, the treatment groups exhibited a prolonged neutrophil chemotaxis distance, significantly decreased expression levels of P2X1 and FPR1 receptors, significantly increased expression levels of CXCR1 and CXCR2 receptors (P < 0.05), and significantly decreased calcium ion concentrations (P < 0.05). These effects were positively correlated with the Shenfu Decoction dosage.

Shenfu Decoction can improve the chemotactic function of neutrophils, possibly through the downregulation of P2X1 receptor expression. Its effects are positively correlated with the dosage.

Hepatocellular carcinoma (HCC) represents the most prevalent malignancy in Egypt and globally. However, non-invasive diagnostic/prognostic biomarkers for early detection of HCC are still lacking. Circular RNAs (circRNAs) are one of the promising biomarkers. They are considered stable, long-stranded non-coding RNAs in a sealed circular form held together by covalent bonds. circRNAs have been observed in several genetic studies to play a vital role in the initiation and progression of malignancy. Our current cross-sectional study aimed to evaluate the potential role of serum-derived hsa_circ_101555 as a diagnostic biomarker for HCC, in addition to comparing its prognostic significance and predicting the response to therapy.

The serum expression level of hsa_circ_101555 was measured using real-time polymerase chain reaction in 62 clinically/radiologically diagnosed Egyptian HCC patients at baseline and three months after HCC treatment. These results were compared to those of 30 healthy subjects.

Our data showed that the mean circRNA value was highest in HCC cases (7.66 ± 3.74) compared to healthy controls (1.21 ± 0.96). Furthermore, the circRNA value showed excellent diagnostic accuracy in differentiating HCC patients from healthy controls at a cutoff point of 1.966, as indicated by an area under the curve of 0.984. In addition, it showed a prognostic role in differentiating between HCC progression and regression in these patients based on response evaluation criteria in solid tumors (RECIST)/ modified- RECIST (mRECIST) response categories at the cutoff point 5.1150, with an area under the curve of 0.891 and a standard error of 0.058. Interestingly, positive correlations between post-intervention circRNA levels and laboratory measurements were observed in our HCC patients, including the albumin-bilirubin score (r = 0.424, P = 0.001**), the neutrophil-to-lymphocyte ratio (r = 0.410, P = 0.001**), alpha-fetoprotein (r = 0.273, P = 0.032*), the aspartate aminotransferase/alanine aminotransferase ratio (r = 0.284, P = 0.025*), fibrosis-4 (r = 0.501, P = 0.000**), and the aspartate aminotransferase to platelet ratio score (r = 0.436, P = 0.000**), indicating an association with worsening liver inflammation, fibrosis, and disease progression. Lastly, post-intervention circRNA values were significantly correlated with clinical/pathological tumor key features, including larger tumors (>5 cm) (P = 0.019), multiplicity (tumor numbers > 3) (P = 0.031), vascular invasion (P = 0.030), Barcelona Clinic Liver Cancer stage C (P = 0.007), and advanced Tomur, Node, Metastasis stage (P = 0.012).

To our knowledge, this is the first study to highlight the expression levels of serum-derived hsa_circ_101555 in Egyptian HCC patients. Our data showed its upregulation in HCC cases compared to healthy subjects. Additionally, its increased levels were associated with tumor progression according to the RECIST/mRECIST categories. Furthermore, its significant correlation with markers/scores of liver inflammation, dysfunction, and tumor pathological features underscores its potential as a promising diagnostic/prognostic biomarker, aiding in better clinical decision-making for the management of hepatocellular carcinoma.

Gastrointestinal complications are common in patients after ischemic stroke. Gastric motility is regulated by gastric pace-making activity (also called gastric myoelectrical activity (GMA)) and autonomic function. The aim of this study was to evaluate GMA, assessed by noninvasive electrogastrography (EGG), and autonomic function, measured via spectral analysis of heart rate variability derived from the electrocardiogram in patients with ischemic stroke.

EGG and electrocardiogram were simultaneously recorded in both fasting and postprandial states in 14 patients with ischemic stroke and 11 healthy controls. Multi-channel surface EGG was used to measure GMA, and autonomic function was evaluated by heart rate variability spectral analysis.

Compared to healthy subjects, patients with ischemic stroke, especially those with a modified Rankin scale ≥ 4, had impaired GMA in both fasting and postprandial states. This included a lower percentage of normal gastric slow waves (the basic rhythmic waves of GMA) and a higher percentage of tachygastria, bradygastria, or arrhythmia. Patients with ischemic stroke also showed a decrease in the dominant frequency and power of the gastric slow waves. Autonomic functions were altered in ischemic stroke patients with a modified Rankin scale ≥ 4, as reflected by increased sympathetic activity and reduced parasympathetic activity.

Gastric pace-making activity is impaired in patients with severe ischemic stroke, as evidenced by a reduced percentage of normal gastric slow waves and a lower frequency of gastric slow waves, likely due to impaired autonomic functions.

Patients with acute liver failure (ALF) or acute-on-chronic liver failure (ACLF) are at high risk of bleeding with traditional artificial liver support systems. To address the bleeding risk in liver failure patients, the safety of regional mesylate anticoagulation (RMA) in centrifugation artificial liver support systems (cALSS) is proposed for study.

In this prospective single-arm study, ALF and ACLF patients were treated with cALSS using RMA. Coagulation function was monitored, and the predictors of mesylate dose were analyzed using the area under the curve (AUC). Blood ammonia, model for end-stage liver disease scores, and survival rates at 28 and 90 days were assessed.

All 57 patients showed no new bleeding within 24 h post-cALSS. Most disseminated intravascular coagulation indicators improved at 0.5 h and 24 h post-cALSS. Thromboelastography showed hypocoagulability at 0.5 h post-cALSS. Univariate and multivariate analyses identified pre-R and pre-MA as key factors for R exceeding 10 m at 0.5 h post-cALSS, with odds ratios of 0.91 (95% confidence interval (CI): 0.84–0.98) and 2.03 (95% CI: 1.05–3.90), respectively, P < 0.05. The predictive values were pre-MA ≤ 38 mm (AUC = 0.817, 95% CI [0.690–0.907], P < 0.001) and pre-R > 6.3 m (AUC = 0.790, 95% CI [0.661–0.888], P < 0.001). Patients showed improvements in blood ammonia and model for end-stage liver disease scores after the last session, especially those with high initial levels (>80 µmol/L and >30). The 28-day and 90-day survival rates of ALF patients were similar to those of ACLF patients.

cALSS with RMA is safe for liver failure patients with a high risk of bleeding. Adjusting the mesylate dose based on pre-R and pre-MA enhances safety.

Breast cancer is the most common cancer among women, with hormone receptors playing a crucial role, not only in cancer cell growth but also as primary targets in breast cancer treatment. This systematic literature review aimed to summarize the current evidence on estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) discordance rates between primary and recurrent breast cancer. Additionally, it seeks to identify how discordance affects prognosis, metastasis, and the potential evidence of primary tumor heterogeneity.

The databases Web of Science, Scopus, MEDLINE, and PubMed were searched for publications of original research in English from 2013 to 2023. Studies with paired histopathology from primary and recurrent breast cancer that employed immunohistochemistry and fluorescence in situ hybridization were included. Ten studies were deemed eligible for inclusion.

Concordance between primary and recurrent breast cancer was high for ER (80%), PR (65%), and HER2 (85%). Average discordance rates were: ER 19%, PR 34%, and HER2 15%, with PR discordance consistently being the highest. Loss of ER and PR receptors was observed more frequently than gain, while the opposite trend was noted for HER2. Loss of ER and PR was associated with a worse prognosis. Discordance was also observed in cases of tumor metastasis.

Discordance in receptor expression between primary and recurrent breast cancer was common, highlighting the importance of re-biopsy in recurrent or metastatic breast cancer, if possible. Patients who lost hormone receptors experienced worse outcomes, suggesting the development of treatment-resistant tumor clones.

Leishmaniasis is a systemic parasitic disease that can affect unusual sites such as the lungs.

We report a case of a 45-year-old male with human immunodeficiency virus infection who presented with abdominal pain and vomiting. Imaging studies revealed minimal bilateral ground-glass opacities in the lungs, hepatosplenomegaly, and diffuse lymphadenopathy. A bronchoscopy with bronchoalveolar lavage cytology evaluation showed abundant macrophages containing numerous intracellular organisms with characteristic dot-like kinetoplasts, confirming the diagnosis of Leishmaniasis. Special stains for other infections were negative.

This case highlights the value of bronchoalveolar lavage cytology in diagnosing non-neoplastic lung pathologies, including parasitic infections like Leishmaniasis, thereby enabling prompt and targeted treatment.

FMS-like tyrosine kinase 3 (FLT3) mutations are among the most common genetic alterations in acute myeloid leukemia (AML) and play a pivotal role in leukemogenesis. The two primary mutation types, internal tandem duplications (ITDs) and tyrosine kinase domain point mutations, serve as key prognostic markers and therapeutic targets. Advances in next-generation sequencing (NGS) have revolutionized FLT3 mutation detection by providing precise insights into mutation architecture, enhancing risk stratification, and enabling personalized treatment strategies. Additionally, these advancements have facilitated molecular minimal residual disease (MRD) testing, which is instrumental in guiding post-remission management. This review summarizes the molecular characteristics, diagnostic approaches, and therapeutic implications of FLT3 mutations in hematologic malignancies.

A narrative review of the current literature on FLT3 mutations was conducted, incorporating data from original research articles, clinical trials, and recent reviews. Relevant studies were identified through a PubMed literature search and manually curated.

FLT3 mutations are detected in approximately 30% of AML cases and occur at lower frequencies in myelodysplastic syndromes, chronic myelomonocytic leukemia, acute lymphoblastic leukemia, and mixed phenotype acute leukemia. NGS enables comprehensive mutation profiling, revealing rare variants and subclonal complexity while supporting MRD detection with high analytic sensitivity. FLT3-ITD-based MRD positivity is strongly associated with relapse and poor survival in AML. Clinical trial data support FLT3 inhibitors, including midostaurin, gilteritinib, and quizartinib, in FLT3-mutated AML. Additionally, MRD-guided therapy and combination treatment strategies are promising approaches to overcoming resistance.

FLT3 mutations play a central role in the pathogenesis and treatment of AML and related malignancies. NGS-based testing and MRD monitoring transform clinical decision-making by refining risk stratification and enabling personalized therapeutic interventions. Establishing standardized testing protocols and the broader integration of FLT3-targeted therapies will be essential for optimizing patient outcomes.
