Molecular analysis of breast cancer tissue has revealed that breast cancer is not a uniform disease. Each breast cancer patient has several molecular signatures that differ from those of others. Therefore, breast cancer therapy should be personalized, depending on its molecular signatures. Breast cancer with hormonal receptors can be treated with a selective estrogen receptor modulator or selective estrogen receptor degrader therapy, while breast cancer with overexpression of human epidermal growth factor receptor 2 (HER2)-neu gene responds excellently to anti-HER2-neu therapy. For patients with advanced breast cancer that already has distant metastasis and a poor prognosis, a new agent has been discovered. The phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA) inhibitor has been proven effective in treating advanced breast cancer with a PIK3CA gene mutation. This therapy can be administered to HER2-negative breast cancer patients and in combination with selective estrogen receptor degrader therapy for post-menopausal patients with positive hormonal receptors. Although this treatment is effective, it cannot be given to every advanced breast cancer patient. Before administering the treatment, a PIK3CA mutation test is compulsory. PIK3CA mutation detection in breast cancer can predict the cancer’s response to the PIK3CA inhibitor, providing information on which patients will benefit from the treatment.

Erdheim-Chester Disease (ECD) is a type of systemic histiocytosis mostly observed in adults, characterized by the infiltration of foamy CD68+ and CD1a- histiocytes into multiple organ systems, often associated with MAPK pathway mutations. Conventional treatment of ECD has been challenging. Currently, targeted drugs (BRAF and MEK inhibitors) are recommended. This report aimed to describe the necessity of targeted therapy for ECD. A 39-year-old Japanese man presented with complaints of weight loss, polyuria/polydipsia, bilateral leg pain, and facial xanthoma/xanthelasma palpebrarum (XP) lesions. A biopsy of the bone lesions confirmed BRAF-positive ECD. The ECD lesions initially showed a good response to the cladribine/dexamethasone regimen; however, XP lesions were exacerbated during infliximab therapy, and did not respond to other conventional regimens. Eventually, XP lesions improved with trametinib (a MEK inhibitor) and dabrafenib (a BRAF inhibitor). Targeted therapy is indispensable in the management of ECD.

Human papillomavirus (HPV)-related oropharyngeal cancers associated with sexual contact are increasing, with high rates in men who have sex with men. HPV-related cancers have the advantage of being frequently detectable through oropharyngeal visual examination and having much higher survival rates than classic oropharyngeal cancers. It has been demonstrated that gay and bisexual men can take smartphone oropharyngeal “selfies” of sufficient quality for screening. However, there is an issue with the inability to move the tongue to allow a clear view of the palatine tonsils, where a majority of oropharyngeal cancer cases occur. We attempted to investigate the feasibility of using commercially available videoscopes to visualize the oropharynx. Fourteen healthy volunteers used a provided low-cost commercial endoscope to video their oropharynx. Participants used the videoscope connected to a laptop and could visualize the oropharynx on the screen. Attempts were observed, and the process was noted. A focus group of participants was carried out immediately afterwards to ascertain barriers and facilitators to using the videoscopes. All participants were able to use the videoscope and obtain videos of sufficient clarity to note major oropharyngeal landmarks. The palatine tonsils were initially difficult to visualize because the tongue could not be sufficiently controlled. Participants were given time to practice using visual cues to control the position of the tongue, which helped in obtaining good videos. Videoscopes can be used effectively with minimal instruction and provide a better view than still images, as they illuminate and magnify the site. Low-cost commercially available videoscopes may be an improvement over smartphone “selfies”.

Oral squamous cell carcinoma (OSCC) is a predominant type of head and neck cancer in the Indian subcontinent, mostly observed among tobacco and/or alcohol users. Oral leukoplakia (OLK) does not seriously affect patients, so it is often ignored in treatment. Some studies have reported genomic alterations and expression deregulation that drive OLK towards OSCC, conducted in two types of studies based on sample collection from (a) disparate or (b) the same patients. Demographic, tobacco/alcohol habits and biological factors may vary significantly if OLK and OSCC samples are collected from disparate patients, but they remain consistent if both tissue samples are from the same patient. Earlier, both targeted candidate gene-based and large-scale omics-based studies identified somatic mutations in TP53, CDKN2A, and PTEN, as well as broad arm-level copy number alterations and epigenetically dysregulated genes in leukoplakia and tumor tissues from disparate patients. Recent omics-based studies have identified early CASP8 somatic alterations, APOBEC mutagenesis, as well as dysregulated immune cell infiltration (decreased CD8+ T cell abundance, enrichment of pro-inflammatory immune cells) as candidate driver events for oral tumor progression from leukoplakia in the same patient. Recent single-cell transcriptomic-driven studies have also identified immune-transcriptomic features as putative driving molecular events in oral tumor development and progression. Here, we reviewed reported differences in driving gene mutations and expression deregulations in disparate and same patient settings. We also highlighted the challenges in sample collection and the opportunity of genomics and transcriptome studies for their emerging role in early diagnosis and progression.

Several studies have suggested that rose hip extracts have anti-obesity potential. Conventional medicines treating obesity are followed by multiple adverse side effects and is very cost full to society. This makes the investigation of herbal remedies with anti-obesity effects potential highly relevant. This systematic review aims to shed light on the results of existing literature reports on the correlation between the intake of rose hip extracts and anti-obesity effects.

A systematic literature search of PubMed and Web of Science was made to localize relevant experimental literature. Nine articles met the inclusion criteria, including one in vitro study, seven in vivo animal studies, and one human trial with pre-obese subjects. All nine articles are objectively reviewed in this systematic review.

Eight out of nine articles, including the article on humans, presented significant anti-obesity effects. Though some limitations of the studies were found, including the human trial, seven possible metabolic mechanisms are suggested as the underlying cause of the significant effects.

Based on the findings of this review, rose hip extracts containing tiliroside found in the seeds have the potential to become a new herbal remedy with anti-obesity effects. Nevertheless, more research is needed to assess the effectiveness and optimal dosage of the rose hip treatment and to elucidate the underlying mechanisms of the effects.

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of aggressive B-cell non-Hodgkin lymphoma. While a substantial fraction of patients are cured with frontline chemoimmunotherapy, approximately 30% of cases subsequently relapse. DLBCL immune evasion and refractory disease can occur via several mechanisms: downregulation or loss of major histocompatibility complex expression, immune checkpoint activation, tumor microenvironment modulation, and resistance to apoptosis. Addressing these mechanisms of immune evasion in DLBCL has been a focus of ongoing research, leading to the exploration of new therapies. Here, we review the mechanisms of immune evasion and novel immunotherapy treatment strategies for DLBCL.

Breast cancer metastases to the lower gastrointestinal tract (small bowel and colon) are rare, but there is a growing number of case reports in the literature. The overall incidence of this condition is not well established, and there might be underdiagnosis. The clinical presentation and endoscopic findings are often nonspecific and variable, potentially leading to misdiagnosis or underdiagnosis. Moreover, there are currently no guidelines for gastrointestinal surveillance of these patients. Given the potential diagnostic challenges, a high level of clinical suspicion is necessary. We present a clinical case to highlight subtle endoscopic findings of breast cancer metastasis to the colon, followed by a review summarizing the available literature on breast cancer metastases to the duodenum, jejunum, ileum, colon, rectum, and anus focusing on the clinical presentation, endoscopic features, imaging modalities, treatment, and outcome.

Infection with HPV16, a high-risk human papillomavirus (HPV), can cause cervical cancer in humans. These infections carry a high risk of morbidity and mortality globally in females. This study aimed to conduct an in vivo comparison of Poly (D,L-lactic-co-glycolide) (PLGA)-encapsulated peptide mixture nanoparticles and PLGA microspheres as delivery systems for vaccines.

PLGA polymers were used to form microspheres for a therapeutic vaccine against cervical cancer. The target antigens were the L1 and L2 capsid proteins and the E6 and E7 oncoproteins from HPV16. These antigens were selected based on their immunogenicity, allergenicity, and toxicity. We predicted epitopes for cytotoxic T lymphocytes (CTLs) and helper T lymphocytes. In our investigation of CTL epitopes, we employed synthetic chimeric PLGA microsphere peptides, consisting of multiple H-2Db-restricted HPV16 peptides, coupled with other immune-potentiating adjuvants as predicted by our work.

H-2Db-restricted HPV16 peptides, when administered subcutaneously, enabled CTLs to eliminate in vitro TC-1 tumor cells expressing E6 and E7 of HPV16. Additionally, TC-1 cells protected C57BL/6 mice against in vivo challenges. To address this problem, peptide-based vaccines, which are among the most effective vaccine systems, have been extensively studied. Combining peptide-based vaccinations with microsphere peptide mixture particles and delivery technologies enhances their efficacy in stimulating cellular immune responses and eliminating tumor cells.

This approach may provide a potential therapeutic candidate vaccine based on microsphere-encapsulated peptides for the prevention of cervical cancer caused by HPV.

Alzheimer’s disease (AD), an enduring neurodegenerative malady, contributes significantly to dementia cases, with late-onset AD being more common than early-onset AD. Despite extensive research to diagnose and treat AD, the intricate protein network impedes the development of efficacious drugs or targets. This study endeavored to identify previously undiscovered genetic reservoirs associated with AD progression, which could be targeted as therapeutic markers.

Employing the robust tools of R-language, we dissected vast RNA sequence datasets comprising numerous samples and thousands of genes, pinpointing potential candidates implicated in AD’s trajectory. Thus, we selected the GSE203206 dataset, which includes AD patients and non-dementia controls, based on our criteria. After normalization, RNA-Seq data was compared, and log2fold change was calculated to determine the highly dysregulated genes. Further network analysis of genes and their associated miRNA was performed to determine a characteristic change in control and patient groups.

Differential expression analysis revealed 13 dysregulated genes in AD, wherein 12 were upregulated, and one was down-regulated. Furthermore, we identified hsa-miR-30-5p as a significant miRNA associated with AD, aligning with previous studies and highlighting its high involvement.

This investigation has unveiled four novel genes and a paramount miRNA implicated in AD, thus furnishing potential targets for therapeutic interventions. These discoveries pave the way for further exploration into the intricate functions and implications of these genetic entities in AD.

Ulcerative colitis (UC) is a chronic autoimmune disease that mainly affects the rectum and colon. The symptoms primarily include abdominal pain, diarrhea, and bloody stools. The incidence of UC continues to increase each year. Bear bile powder (BBP) is a well-known traditional medicine that remains in use due to its outstanding efficacy. This study aimed to elucidate the therapeutic effects and molecular mechanisms of BBP on dextran sulfate sodium (DSS)-induced UC.

DSS-induced UC model mice were created and then randomly assigned to the following groups: control, DSS-treated, 5-amino salicylic acid-treated, BBP low dose, and BBP high dose. Treatment was administered by gavage. Disease activity index, body weight loss, colon histopathology, colon length, and the expression of inflammatory cytokines were measured. Samples of the intestinal content were collected, and differences in the gut microbiota were analyzed by 16S rDNA sequencing.

The experimental results demonstrated that BBP significantly alleviated the symptoms and histopathological scores in UC mice, reduced the production of interleukin-6, interleukin-1β, tumor necrosis factor-α, malondialdehyde, nitric oxide, and myeloperoxidase, and upregulated the expression of cyclic adenosine monophosphate (cAMP), protein kinase A, and cAMP-response element binding protein. Moreover, 16S rRNA sequencing revealed that the gut microbiota of mice in the DSS-treated group was disordered compared to the control group. The abundance of gut microbiota in the treatment groups improved to varying degrees.

Together, these results indicate that BBP significantly improves the inflammatory symptoms of mice with acute colitis, which may be related to its upregulation of the cAMP/protein kinase A/cAMP-response element binding protein signaling pathway, inhibition of NOD-like receptor thermal protein domain associated protein 3 inflammasome secretion, and regulation of gut microbiota.

Acute-on-chronic liver failure (ACLF) is a distinct condition characterized by the abrupt exacerbation of pre-existing chronic liver disease, often leading to multi-organ failures and significant short-term mortalities. Bacterial infection is one of the most frequent triggers for ACLF and a common complication following its onset. The impact of bacterial infections on the clinical course and outcome of ACLF underscores their critical role in the pathogenesis of systemic inflammation and organ failures. In addition, the evolving epidemiology and increasing prevalence of multidrug-resistant bacteria in cirrhosis and ACLF highlight the importance of appropriate empirical antibiotic use, as well as accurate and prompt microbiological diagnosis. This review provided an update on recent advances in the epidemiology, diagnosis, pathogenesis, and management of bacterial infections in ACLF.

Hepatocellular carcinoma (HCC) is a highly aggressive tumor with limited treatment options and high mortality. Senecavirus A (SVA) has shown potential in selectively targeting tumors while sparing healthy tissues. This study aimed to investigate the effects of SVA on HCC cells in vitro and in vivo and to elucidate its mechanisms of action.

The cell counting kit-8 assay and colony formation assay were conducted to examine cell proliferation. Flow cytometry and nuclear staining were employed to analyze cell cycle distribution and apoptosis occurrence. A subcutaneous tumor xenograft HCC mouse model was created in vivo using HepG2 cells, and Ki67 expression in the tumor tissues was assessed. The terminal deoxynucleotidyl transferase dUTP nick end labeling assay and hematoxylin and eosin staining were employed to evaluate HCC apoptosis and the toxicity of SVA on mouse organs.

In vitro, SVA effectively suppressed the growth of tumor cells by inducing apoptosis and cell cycle arrest. However, it did not have a notable effect on normal hepatocytes (MIHA cells). In an in vivo setting, SVA effectively suppressed the growth of HCC in a mouse model. SVA treatment resulted in a significant decrease in Ki67 expression and an increase in apoptosis of tumor cells. No notable histopathological alterations were observed in the organs of mice during SVA administration.

SVA inhibits the growth of HCC cells by inducing cell cycle arrest and apoptosis. It does not cause any noticeable toxicity to vital organs.

Malaria can be fatal during pregnancy, posing a serious risk to both mothers and fetuses, especially in sub-Saharan Africa. Primigravidae are particularly susceptible to placental malaria in areas with high rates of transmission due to insufficient immunity. This study aimed to determine the prevalence of placental malaria infection, risk factors, types of Plasmodium causing malaria during pregnancy, and its relationship with neonatal birth weight among primigravidae.

This was an analytical cross-sectional study involving 357 primigravidae who delivered at Abubakar Tafawa Balewa University Teaching Hospital, Bauchi, Nigeria. Placental blocks were taken from the pericentric area of the maternal surface of the placenta, and the birth weights of the neonates were recorded. The samples were fixed in 10% neutral-buffered formalin, and histopathological analysis was performed. The primary outcome measure was to determine the relationship between placental malaria and neonatal birth weight. Demographics and outcomes were analyzed using standard statistical tests. Multivariable regression models accounting for potential confounders were created for the primary and secondary outcomes with adjusted odds ratios as the measures of effect.

The prevalence of placental malaria was 38.4%. Among the participants with positive placenta malaria parasitemia, 49.6%, 36.5%, and 13.9% had chronic, acute, and past placental malaria infections, respectively. Only Plasmodium falciparum was found in the placenta. According to the bivariate analysis, unbooked status (p = 0.001), non-use of intermittent preventive therapy for malaria (p < 0.001), and village dwelling (p = 0.020) were significantly associated with placental malaria. However, on multivariable logistic regression, only non-uptake of intermittent preventive therapy for malaria was independently associated with placental malaria (adjusted odds ratio, 2.2, 95% confidence interval: 1.20, 4.1, p = 0.011). There was a significant difference in the mean birth weight between those with placental malaria and those without placental malaria (2.8 ± 0.5 kg vs. 3.2 ± 0.4 kg, p = 0.001). Additionally, placental malaria was significantly associated with low birth weight among the primigravidae (p < 0.001).

In Nigeria, there is a strong correlation between low birth weight and placental malaria in Primidravidae. Placental malaria was found to be independently correlated with non-uptake of intermittent preventive therapy for malaria.

Early detection of oral cancer is crucial for improving prognosis, increasing survival rates, and reducing treatment-related morbidity, considering the high mortality rate associated with this condition. However, the conventional approach within communities has led to a growing exploration of different screening methods to detect potentially malignant oral disorders, with particular emphasis on imaging and artificial intelligence and their integration with conventional approaches. The article reviewed literature on oral neoplasms and early cancer detection from databases like Medline, Google Scholar, and Web of Science, mainly from 2001 to 2023. This review aims to shed light on the potential of these technologies, new ideas, and methods in improving the accuracy and effectiveness of oral cancer screening, ultimately leading to earlier detection and more successful prevention strategies, which are unmet needs, especially in underdeveloped and developing nations.

Molecular testing has emerged as a valuable tool for stratifying cytologically indeterminate thyroid nodules (ITNs), with Harvey rat sarcoma viral oncogene homolog/neuroblastoma RAS viral oncogene homolog (HRAS/NRAS) mutations being among the most prevalent molecular alterations. The study aimed to evaluate the malignancy risk of ITNs with these mutations.

We conducted a retrospective study involving ITNs (Bethesda category III and IV) that underwent ThyroSeq testing between February 2016 and January 2022. A smaller subset of ITNs also underwent Afirma testing. We specifically identified nodules with HRAS/NRAS mutations and collected radiological, clinical, histological, and follow-up data.

Our analysis identified 45 ITNs with NRAS (29 cases) and HRAS (15 cases) mutations. Of the 29 nodules with NRAS mutations, 25 underwent surgical treatment (14 total thyroidectomies and 11 hemithyroidectomies), resulting in a surgical resection rate of approximately 86%. Among the resected nodules, six were malignant, yielding a calculated risk of malignancy (ROM) ranging from 20.6% to 25%. Three of these malignant nodules were managed with total thyroidectomy, while the other three underwent hemithyroidectomy. During a follow-up period of 43.8 months for total thyroidectomy and 32.9 months for hemithyroidectomy, no recurrence or metastasis was detected among the patients. Among the four nodules treated conservatively, three remained stable, with an average follow-up duration of 34.7 months, while one patient was lost to follow-up. Regarding HRAS mutations, 15 nodules were identified, with 12 of them undergoing surgical treatment (six total thyroidectomies and 6 hemithyroidectomies), resulting in an 80% surgical resection rate. Two of the resected nodules were malignant, with a calculated ROM of 13.3% to 16.7%. Both malignant nodules were managed with total thyroidectomy, and during a follow-up period of 37.9 months, no recurrence or metastasis occurred. Of the three nodules managed conservatively, all remained stable, with an average follow-up duration of 31.1 months.

The ROM for nodules with NRAS (20.6–25%) or HRAS (13.3–16.7%) mutations was found to be low. Therefore, before opting for total thyroidectomy, conservative management, including limited resection, should be considered as a viable alternative.

Despite efforts, tumor recurrence is diagnosed in 35–40% of patients with stage III squamous cell lung carcinoma (SCLC) during the first year after treatment. The purpose of the present investigation was to determine the levels of cytokeratin-fragment 19 (CYFRA 21-1) in blood serum, the percentages of lymphocytes containing chemokine receptor 1 (CXCR1, %, lymphocytes), and the percentages of monocytes containing chemokine receptor 2 (CXCR2, %, monocytes), as well as their combined model before and after treatment for the early detection of recurrence.

Forty-eight patients (29 men and 19 women) with newly diagnosed stage III SCLC were examined. Serum levels of CYFRA 21-1, CXCR1, %, lymphocytes, and CXCR2, %, monocytes in peripheral blood were measured before treatment and at three weeks, three months, and six months after treatment using a chemiluminescence immunoassay analyzer and a flow cytometer, respectively.

The levels of all determined indicators, which were elevated before treatment, decreased sharply three weeks after treatment. Subsequently, three months and six months after treatment, the levels steadily increased in patients with diagnosed tumor recurrence. The differences in these indicators in three weeks to three months, three months to six months, and three weeks to six months after treatment, when included in a regression equation, corresponded to the presence of recurrence with accuracies of 83.3%, 91.7%, and 95.8%, respectively.

Determining the combination of CYFRA 21-1 levels, CXCR1, %, lymphocytes, and CXCR2, %, monocytes in the blood of patients with stage III SCLC is important for assessing the probability of recurrence after treatment.
