Conservative and Radical Surgery vs. BRAF-Target Therapy for Recurrent Ameloblastoma

2024-08-12T07:51:57+07:00

Highlights

Ameloblastoma is a widely discussed odontogenic tumor, yet research on less invasive treatment options for recurrent cases remains limited.
BRAF-targeted therapy offers a less invasive approach that may reduce the extent of surgical intervention required.

ABSTRACT

Background: Ameloblastoma is a benign odontogenic tumor that can affect surrounding tissues and is prone to recurrence if not completely excised. Surgical therapy is currently the primary treatment modality. However, recurrences are common following prior surgical interventions. Recently, a novel approach involving BRAF (B-Rapidly Accelerated Fibrosarcoma)-targeted therapy has been introduced, aiming to prevent molecular mutations. This therapy is non-invasive, but its efficacy in treating recurrent ameloblastoma remains uncertain. Objective: This article aimed to compare the outcomes of conservative and radical surgery with BRAF-targeted therapy in the management of recurrent ameloblastoma. Material and Method: An electronic search was conducted using the PubMed and Scopus databases. Relevant studies were selected based on predefined inclusion criteria. Results: A total of nine studies were included in the analytical synthesis. Recurrence in ameloblastoma is often due to residual tumor tissue located in anatomically challenging areas following surgery. BRAF-targeted therapy has emerged as a promising option for patients with recurrent disease, offering precise tumor targeting and potentially reducing the need for further surgical intervention. Conclusion: Surgical and BRAF-targeted therapies each offer benefits in managing recurrent ameloblastoma. While recurrence is often linked to residual tumors in complex anatomical areas, BRAF-targeted therapy provides a non-invasive, precise alternative—especially for patients with multiple recurrences. It can reduce tumor size, improve lesion localization, and potentially limit the need for extensive surgery.

Investigating the Prospect of C-Type Lectin-like Receptors-2 for Predicting Prognosis of Ischemic Stroke: Rapid Review of Molecular Mechanisms to Clinical Study

2025-03-01T10:39:36+07:00

Highlights

The potential of CLEC-2 as a prognostic biomarker for ischemic stroke is supported by in vivo and clinical studies demonstrating its role in thrombo-inflammatory mechanisms and clinical outcome prediction.
Analysis of clinical studies indicates that elevated plasma CLEC-2 levels are associated with an increased risk of recurrent vascular events and mortality in acute ischemic stroke, suggesting its promise as a noninvasive tool for stroke prognosis assessment.

ABSTRACT

Background: Every year, over 13.7 million individuals experience strokes, resulting in approximately 5.8 million deaths. C-type lectin-like receptor 2 (CLEC-2) plays a significant role in platelet activation, which is elevated in ischemic stroke and is associated with disease progression and prognosis. Objective: To review the literature on the potential of CLEC-2 as a biomarker for assessing the prognosis and progression of ischemic stroke. Material and Method: This rapid review followed the Cochrane interim guidelines and adhered to PRISMA standards. A comprehensive search was conducted in PubMed, Cochrane Library, and Google Scholar to identify original research articles published in English over the past 10 years. Studies at various stages—including in vitro, in vivo, and clinical trials—were included if they evaluated the association between CLEC-2 and acute ischemic stroke. Risk of bias was assessed using the QUIPS tool for clinical studies and SYRCLE’s tool for animal studies. Study selection and data extraction were performed independently by three reviewers. Result: The search identified five relevant articles: two experimental studies and three clinical prognostic studies examining CLEC-2 in the context of ischemic stroke. CLEC-2, a receptor for podoplanin expressed in various tumors and lymphatic endothelial cells, induces a calcium surge independent of secondary platelet activation. In vivo studies have demonstrated increased levels of CLEC-2 and podoplanin, which are highly expressed on neurons and microglia in ischemic brain regions. The three clinical studies showed that plasma CLEC-2 levels have prognostic value in predicting recurrent vascular events and mortality in patients with acute ischemic stroke. Conclusion: Plasma CLEC-2 shows potential as a biomarker for evaluating the progression and prognosis of acute ischemic stroke.

The 96% ethanol extract of papaya seeds exhibits antibacterial activity against Staphylococcus aureus and Klebsiella pneumoniae.

ABSTRACT

Background: Pneumonia is an infectious disease with the highest childhood mortality rate worldwide, commonly caused by Staphylococcus aureus and Klebsiella pneumoniae, which have developed resistance to antibacterial agents. Papaya seeds have traditionally been used in Indonesian medicine due to their bioactive compounds, which are expected to exhibit antibacterial properties. Objective: To analyze the antibacterial effect of 96% ethanol extract of papaya seeds against S. aureus and K. pneumoniae in vitro. Material and Method: This study employed a true experimental design with a posttest-only control group. Ethanol extracts of papaya seeds at concentrations of 10%, 30%, and 50% were tested using the well diffusion method. Erythromycin and chloramphenicol were used as positive controls, and 70% alcohol served as the negative control. Inhibition zone diameters were analyzed using SPSS version 29 with the non-parametric Kruskal-Wallis and Mann-Whitney tests. Results: The ethanol extract of papaya seeds inhibited the growth of S. aureus starting at a concentration of 10%, with the largest inhibition zone observed at 50%. Against K. pneumoniae, the extract demonstrated the lowest effective inhibitory concentration at 30%, which also produced the largest inhibition zone. However, the extract was less effective than the antibiotics used. Conclusion: The ethanol extract of papaya seeds exhibits antibacterial activity against both S. aureus and K. pneumoniae, with a more pronounced effect on S. aureus.

Ganyong tuber extract increases phagocytic activity, leukocyte count, and spleen weight in infected mice.

ABSTRACT

Background: Ganyong tubers (Canna edulis K.) are widely consumed by Indonesians as an alternative food source. However, no studies have investigated the pharmacological properties of ganyong tubers, particularly their immunomodulatory activity. Objective: This study aimed to evaluate the immunomodulatory effects of ganyong tubers in mice infected with Staphylococcus aureus. Material and Method: This study used a randomized experimental design involving 30 male BALB/c mice divided into five groups, including a normal control, a negative control (infected with Staphylococcus aureus), and three groups treated with ganyong (Canna edulis K.) extract at doses of 50, 100, and 150 mg/kg BW. The extract was administered orally for seven days, followed by S. aureus injection. Phagocytic activity, leukocyte count, spleen weight, and antibody levels were evaluated using microscopy and ELISA. Data were analyzed using one-way ANOVA and Duncan’s post hoc test. Result: This study evaluated the immunomodulatory effects of ganyong tuber (Canna edulis K.) extract on phagocytosis activity and capacity, leukocyte count, spleen weight, and antibody levels in mice infected with Staphylococcus aureus. Phagocytosis activity and capacity were highest in the group receiving 50 mg/kg body weight (BW) extract, with decreasing effects at higher doses. Leukocyte counts were highest in the infected untreated group, while spleen weight was significantly increased in the 50 mg/kg BW treatment group compared to controls. Although the 100 mg/kg BW group showed the highest antibody levels, these differences were not statistically significant. Conclusion: Ganyong tuber extract demonstrated immunomodulatory activity by enhancing innate immune responses against S. aureus infection.

Humerus length can be used to predict stature for the Nias tribe in North Sumatra, Indonesia.

ABSTRACT

Background: The identification of stature is an essential component of forensic anthropology. The measurement of stature with a single long bone of the upper limbs provided an alternative technique for estimating stature when the commonly used lower limb bone is missing. Objective: To determine the correlation between humerus length and stature among Nias ethnic students at HKBP Nommensen University, Medan, Indonesia. Materials and Methods: The study employed correlational analytics with a cross-sectional design. The study population comprises 100 active Nias ethnic students at HKBP Nommensen University, according to the inclusion and exclusion criteria, consisting of 50 males and 50 females. Sampling was done by purposive sampling. Conducting a bivariate analysis to ascertain the correlation between humerus length and stature. The linear regression analysis was conducted to derive a formula for predicting stature from humerus length. Results: The length of the male humerus bone was significantly related to stature, with a correlation coefficient of r = 0.949 (p<0.001). The length of the female humerus bone showed a significant correlation with stature, with correlation coefficients ranging from 0.783 to 0.785 (p<0.001). The precise regression equation is established according to the minimal Standard Error of the Estimate (SEE) value within each sex group. The linear regression equations obtained were the stature of males (cm) = 78.844 + 3.001 x length of left humerus (cm) and the stature of females (cm) = 19.694 + 5.189 x length of right humerus (cm). Conclusion: Among the Nias ethnic students at HKBP Nommensen University, the study discovered a strong correlation between the lengths of the right and left humerus bones and stature. As a result, stature might be calculated using a linear regression equation to measure the humerus length of the bone.
