From Tenofovir Disoproxil Fumarate (TDF) to Tenofovir Alafenamide (TAF): Perspectives in Pediatric Patients with Chronic Hepatitis B.

Introduction: Hepatitis B virus (HBV) affects hundreds of millions globally, with many cases stemming from perinatal transmission. Chronic hepatitis B (CHB) in children can progress to cirrhosis and hepatocellular carcinoma (HCC) in adulthood. Treatment options include interferons and nucleos(t)ide reverse transcriptase inhibitors (N[t]RTIs) such as tenofovir alafenamide (TAF).

Hepatitis E Vaccines Updates.

The development of a hepatitis E vaccine is imperative given its prevalence and the heightened risk it poses to specific populations. Hepatitis E virus infection, though often self-limiting, poses a significant threat to pregnant individuals and immunocompromised populations. This review delves into the historical trajectory of hepatitis E vaccine development and explores its potential impact on at-risk populations.

Direct-Acting Antiviral Agents in Prevention of Maternal-Fetal Transmission of Hepatitis C Virus in Pregnancy.

Prior to the Food and Drug Administration approval of ledipaspavir/sofosbuvir (Harvoni) in 2014, the treatment of hepatitis C was interferon plus or minus ribavirin. This treatment had low cure rates for hepatitis C virus and was teratogenic and therefore avoided in pregnant patients. Vertical transmission is the most common transmission of hepatitis C in pediatric patients, whereas medical equipment that was not properly cleaned and sterilized, blood products which were not checked (historically), sharing and reusing syringes and needles, and dialysis are the most common forms of hepatitis C transmission in adults.

Immunohistochemical expression of interleukin 1 beta in papule biopsies from patients with acne vulgaris.

Acne vulgaris is the most common inflammatory disease of the skin. IL-1b has been found in acne lesions and is a promising target for therapy, but the evidence is limited. Therefore, this study was conducted to investigate the immunohistochemical expression of IL-1b in papule biopsies of inflammatory acne and its association with disease severity.

Serum Zinc Level in Patients with Severe Genital Warts: A Case-Control Study in a Dermatology Hospital.

Background: Genital warts are a common sexually transmitted disease (STD), and there is no method that completely prevents its recurrence. Recently, zinc has been used in the treatment of cutaneous warts. Nondestructive action, ease of use, and promising results with low chances of relapse were reflected in the treatment.

Long-pulsed 1064-nm and 755-nm lasers for C1 leg veins on skin type IV patients: a side-by-side comparison.

Long-pulsed 1064-nm (LP1064) and 755-nm (LP755) lasers have been demonstrated as effective treatments for leg veins. However, few studies of these treatments on Asian skin type as well as direct comparison between two methods were reported. The aim of this study was to compare the clinical efficacy and safety of LP1064 with LP755 in the treatment of C1 leg veins on skin type IV patients.

Evaluate the Results at Minimum 2-Years of Treating Rotator Cuff Tear by Arthroscopic Surgery.

Background: Rotator cuff tear (RCT) is a common injury of the shoulder, especially middle-aged people. Nonoperative treatment, cortisone injections are only effective at an early stage. Open surgery causes postoperative atrophy of the deltoid muscle, so results are limited.

Progressive cutaneous Cryptococcosis complicated with meningitis in a myasthenia gravis patient on long-term immunosuppressive therapy - a case report.

Background: Cryptococcosis is an opportunistic infection caused by the encapsulated yeast Cryptococcus neoformans and most remarkably manifests in HIV-infected individuals, especially in the settings of very low CD4 count. Development of cryptococcosis in HIV-uninfected individuals is exceedingly rare and usually signifies a marked immunodeficiency. Cryptococcosis in association with myasthenia gravis or thymoma has been previously documented in only very few cases in the literature.

Fibrocyte-like cells mediate acquired resistance to anti-angiogenic therapy with bevacizumab.

Bevacizumab exerts anti-angiogenic effects in cancer patients by inhibiting vascular endothelial growth factor (VEGF). However, its use is still limited due to the development of resistance to the treatment. Such resistance can be regulated by various factors, although the underlying mechanisms remain incompletely understood.

Macrophage stimulating protein promotes liver metastases of small cell lung cancer cells by affecting the organ microenvironment.

The organ microenvironment significantly affects the processes of cancer metastasis. Elucidating the molecular mechanisms of interaction between tumor cells and the organ microenvironment is crucial for the development of effective therapeutic strategies to eradicate cancer metastases. Macrophage stimulating protein (MSP), an activator of macrophages, regulates a pleiotropic array of effects, including proliferation, cellular motility, invasiveness, angiogenesis, and resistance to anoikis.

SU6668, a multiple tyrosine kinase inhibitor, inhibits progression of human malignant pleural mesothelioma in an orthotopic model.

Background And Objective: Malignant pleural mesothelioma (MPM) is an aggressive neoplasm of the mesothelium with high chemotherapeutic resistance. In this study, the preclinical therapeutic activity of the multiple tyrosine kinase inhibitor, SU6668, against MPM was examined.

Methods: Two human MPM cell lines with different pro-angiogenic cytokine expression, Y-MESO-14 cells that express high levels of vascular endothelial growth factor (VEGF) and MSTO-211H cells that express high levels of basic fibroblast growth factor (bFGF), were orthotopically inoculated into the thoracic cavities of mice with severe combined immunodeficiency.

Erlotinib prevents experimental metastases of human small cell lung cancer cells with no epidermal growth factor receptor expression.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) show dramatic antitumor activity in a subset of patients with non-small cell lung cancer who have an active mutation in the epidermal growth factor receptor (EGFR) gene. On the other hand, some lung cancer patients with wild type EGFR also respond to EGFR-TKIs, suggesting that EGFR-TKIs have an effect on host cells as well as tumor cells. However, the effect of EGFR-TKIs on host microenvironments is largely unknown.

E7080 suppresses hematogenous multiple organ metastases of lung cancer cells with nonmutated epidermal growth factor receptor.

While epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors improve the prognosis of patients with EGFR mutant lung cancer, the prognosis of patients with nonmutant EGFR lung cancer, especially those with metastases, is still extremely poor. We have assessed the therapeutic efficacy of E7080, an orally available inhibitor of multiple tyrosine kinases including VEGF receptor 2 (VEGFR-2) and VEGFR-3, in experimental multiple organ metastasis of lung cancer cell lines without EGFR mutations. E7080 markedly inhibited the in vitro proliferation of VEGF-stimulated microvascular endothelial cells.

The therapeutic efficacy of S-1 against orthotopically implanted human pleural mesothelioma cells in severe combined immunodeficient mice.

Purpose: Malignant pleural mesothelioma (MPM) is a highly lethal neoplasm. S-1 has been developed as a novel oral antineoplastic agent based on the modulation of 5-fluorouracil (5-FU) bioactivity. This study was conducted to investigate the preclinical therapeutic effect of S-1 on MPM.

E7080, a multi-tyrosine kinase inhibitor, suppresses the progression of malignant pleural mesothelioma with different proangiogenic cytokine production profiles.

Purpose: Malignant pleural mesothelioma (MPM) is a biologically heterogeneous malignant disease with a poor prognosis. We reported previously that the anti-vascular endothelial growth factor (VEGF) antibody, bevacizumab, effectively inhibited the progression of VEGF-high-producing (but not VEGF-low-producing) MPM cells in orthotopic implantation models, indicating the need for novel therapeutic strategies to improve the poor prognosis of this disease. Therefore, we focused on the multi-tyrosine kinase inhibitor E7080 and assessed its therapeutic efficacy against MPM cells with different proangiogenic cytokine production profiles.
