Nail psoriasis is common in patients with plaque psoriasis and is associated with morbidity, including onychomycosis, which can complicate psoriasis treatments and be difficult to differentiate. Matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry is a fast and simple technique for identifying microorganisms through protein analysis. This study aimed to determine the sensitivity and specificity of MALDI-TOF for diagnosing onychomycosis in patients with nail psoriasis, by using conventional mycological and histological methods as the reference standard.

A prospective study was conducted on 88 patients with clinically and histopathologically confirmed nail psoriasis. One hundred nail samples were obtained for direct examination, fungal culture, and mass spectrometry. None of the patients were receiving antifungal or systemic immunosuppressive therapy at the time of sampling.

Potassium hydroxide preparation and fungal culture were positive in 58 out of 100 nail samples from patients with psoriasis. MALDI-TOF identified onychomycosis in 68 out of 100 samples, distinguishing these cases from nail psoriasis without onychomycosis (32 out of 100). An excellent correlation (0.95) was found between MALDI-TOF and conventional onychomycosis diagnostic methods. The sensitivity and specificity of MALDI-TOF for diagnosing onychomycosis in patients with psoriatic nails were 95.4% and 97.5%, respectively.

MALDI-TOF can be used to accurately differentiate cases of nail psoriasis without infection from those with onychomycosis.

Liver fibrosis is a key process in the progression of chronic liver diseases. However, there are currently no drugs specifically designed to treat liver fibrosis. Our Phase 2 trial of hydronidone for the treatment of chronic hepatitis B (CHB)-associated liver fibrosis showed that adding hydronidone to entecavir resulted in significant reversal of liver fibrosis. To further evaluate the efficacy of a 270 mg/day dose of hydronidone for treating liver fibrosis associated with CHB, we conducted this Phase 3 trial.

This is a 52-week, randomized (1:1), double-blind, placebo-controlled, multicenter, entecavir-based Phase 3 clinical study conducted at 44 study centers across China. Adult patients aged 18 to 65 years with significant liver fibrosis (defined as an Ishak score ≥ 3 on liver biopsy) associated with CHB were included.

The primary endpoint of the trial is to demonstrate the efficacy of fibrosis reversal, defined as a decrease in the Ishak stage score of liver fibrosis by ≥1 after 52 weeks of treatment, compared to baseline.

The results of this trial are expected to further support the antifibrotic indication for this novel drug.

Pyrrolizidine alkaloids (PAs), widely distributed in plants, are known to induce liver failure. Hepatic platelet accumulation has been reported during the progression of PA-induced liver injury (PA-ILI). This study aimed to investigate the mechanisms underlying platelet accumulation in PA-ILI.

Cases of PA-ILI, non-PA-ILI, and control subjects were collected from patients hospitalized at Zhongshan Hospital, Fudan University (Shanghai, China) between 2012 and 2019. A mouse model of PA-ILI was established using monocrotaline administration. Liver RNA sequencing was performed, and gene interactions were analyzed using the Search Tool for the Retrieval of Interacting Genes/Proteins online database. Low-molecular-weight heparin and recombinant a disintegrin and metalloproteinase with a thrombospondin type I motif member 13 (ADAMTS13) were applied. The necrotic liver area, hepatic platelet accumulation, and von Willebrand factor (VWF) deposition were examined using hematoxylin and eosin staining and immunofluorescence assay.

Hepatic platelet accumulation, necrotic area expansion, and increased VWF expression were observed in both PA-ILI patients and mice. The Search Tool for the Retrieval of Interacting Genes/Proteins database indicated that ADAMTS13 regulates VWF expression and was differentially expressed in the livers of PA-ILI mice. Plasma and hepatic ADAMTS13 levels were significantly downregulated in both PA-ILI patients and mice. Systemic administration of recombinant ADAMTS13 decreased hepatic platelet accumulation, downregulated VWF expression, and mitigated mouse hepatic necrosis.

Hepatic platelet accumulation in PA-ILI was confirmed in both patients and mice. Deficiency of ADAMTS13 plays a critical role in platelet accumulation in PA-ILI, suggesting that ADAMTS13 could be a potential therapeutic target for this condition.

Prostate cancer is virtually the most common type of cancer, leading to multiple complications within the male gender worldwide. However, prostatic complications have been increasing recently due to probable changes in lifestyles. Affected patients try every treatment technique to confront their cancer. Thus, radiation therapy has been demonstrated to be one of the most efficient lanes of long-term survivorship in men with malignant prostatic cancer. Although radiotherapy has the potential to seem irritating, due to the studies, metastasis-free survival, biochemical recurrence-free survival, and prostate cancer-specific survival have experienced a major increase in various cases of the disease. Subsequently, still, radiation therapy has revealed the superlative approach to avoiding the risk of cancer relapse and case mortalities. This manuscript would radically discuss novel approaches that could probably increase the lifespan and survivorship of patients owning to previous examinations.

Gelsemium elegans Benth (G. elegans) is a traditional medicinal plant; however, it is highly toxic, and toxicity varies significantly between species. The cause of this difference has not been clarified. Humantenirine is an important toxic alkaloid in G. elegans, and its metabolism has been poorly studied. This study aimed to compare the different metabolites formed by human liver microsomes, pig liver microsomes, and goat liver microsomes.

High-performance liquid chromatography/quadrupole time-of-flight mass spectrometry was used to study the metabolism of humantenirine in human liver microsomes, pig liver microsomes, and goat liver microsomes.

A total of eight metabolites (M1-M8) were identified, and three major metabolic pathways were found: demethylation (M1), dehydrogenation (M2, M3, M7), and oxidation (M4, M5, M6, M8).

Based on these results, it is hypothesized that demethylation is the major detoxification pathway for humantenirine, providing important information to better understand the metabolism and toxicity differences between species of G. elegans.

Type 1 bipolar disorder (BP) is a mental illness characterized by extreme shifts in mood, oscillating between manic and depressive episodes. It ranks as the sixth most prevalent psychiatric disorder globally, often emerging in the teenage years. This study aimed to identify associations between BP and 15 insertion/deletion (Indel) polymorphisms in the human genome, examining genes including TPA, UCP2, HLA-G, FADS2, ADRA2B, VEGF, PDCD6IP, SLC6A4, TLR2, APOB, TP53, LRPAP1, DHFR, MDM2, and DBH.

This case-control study involved 226 patients with BP and 235 healthy controls. Allele frequencies for each polymorphism in cases and controls were estimated using pooled samples. Polymerase chain reaction was performed for each Indel polymorphism using pooled samples as templates to estimate allele frequencies.

The data presented herein demonstrate a significant association between a 14bp Ins/Del polymorphism in the HLA-G gene and the risk of BP. The deletion allele of this polymorphism increased the risk of BP (odds ratio = 1.434, 95% confidence interval = 1.106–1.859, p = 0.007). Other 14 Indel polymorphisms were not associated with the risk of BP.

The HLA-G 14bp Indel polymorphism exhibits a significant correlation with the risk of BP in this study. This finding contributes to understanding the etiology of BP.

The years 2019–2021 of the twenty-first century are synonymous with the COVID era, as the Coronavirus disease 2019 (COVID-19) wreaked havoc and continues to be aggressively persecuted. Globally, about 300 million COVID-19 cases and nearly 5.3 million fatalities have been recorded so far. Since then, the coronavirus RNA genome has rapidly mutated, giving rise to several mutant and recombinant variants. On March 9, 2022, a new recombinant known as Deltacron/Delmicron emerged due to inter-lineage recombination between Delta and Omicron. Many researchers consider it a “grey rhino” occurrence rather than a “black swan” event. However, some groups of scientists claim it is a “laboratory error”. Another COVID-19 variant, XE (a recombination of BA.1 and BA.2), has been discovered, which has a transmission rate ten times higher than the fastest-spreading Omicron subvariant BA.2. Delta and Omicron, two of the most novel strains, co-circulated for many weeks in several parts of the globe, allowing for coinfections and eventual recombination. Consequently, the recombinant strains XD and XF are associated with a very high transmission rate and reduced neutralizing antibody response. Under these circumstances, researchers are rushing to develop a vaccine with high efficacy against the circulating mutants and the variants likely to emerge in the near future. This review article provides recent updates on newly identified sub-variants of Omicron with an in-depth focus on their genomic alterations, infectivity patterns, and pathogenic manifestations.

Mesothelioma is an aggressive tumor with a poor prognosis. Histological diagnosis of mesothelioma using limited tissue samples can be challenging. Carbonic anhydrase IX (CAIX) is a transmembrane protein that is overexpressed in a variety of solid tumors. This study aimed to investigate the clinical utility of CAIX expression in the differential diagnosis of pleural mesothelioma from non-small cell lung carcinoma (NSCLC).

Unstained tissue microarray slides composed of 56 cases of pleural mesothelioma and 82 cases of NSCLC were subjected to immunohistochemical staining using a mouse anti-human antibody against CAIX.

Of the 38 epithelioid mesothelioma cases, 34 (89%) displayed diffuse and strong cytoplasmic membrane reactivity, while the remaining four cases (11%) showed weak to moderate staining in tumor cells. Five out of sixteen (5/16) sarcomatoid mesothelioma cases were negative. Among the non-small cell lung carcinoma cases, 76% (32/42) of adenocarcinomas and 57% (21/37) of squamous cell carcinomas were completely negative, whereas the remaining cases showed focal weak expression of CAIX.

Our study demonstrates that CAIX expression has a high sensitivity (100%) in detecting pleural epithelioid mesothelioma, which is comparable to or better than currently used mesothelial markers. The specificity of CAIX is within a comparable range to that of commonly used mesothelial markers for differentiating epithelioid mesothelioma from NSCLC. Therefore, we recommend that CAIX immunohistochemistry staining be considered as an additional tool for the differential diagnosis of mesothelioma, particularly pleural epithelioid mesothelioma, from its common mimicker, NSCLC.

Cancer continues to pose a substantial public health problem in Nigeria, characterized by rising rates of occurrence and mortality. While there is increasing interest in using natural products for cancer treatment, comprehensive data on the specific bioactive compounds in these plants and how they modulate different types of cancer are still lacking. Additionally, although traditional knowledge about these food plants is rich and valuable, it has not been fully integrated with modern scientific research to create standardized treatment protocols. Scientific databases like PubMed, ScienceDirect, Google Scholar, and ResearchGate were explored to retrieve empirical data. The key plants discussed are Spondias mombin, Xanthosoma sagittifolium, Elaeis guineensis, Irvingia gabonensis, Allium cepa, Blighia sapida, Dioscorea dumetorum, Psidium guajava, and Talinum triangulare. These plants demonstrate a wide range of anticancer properties, including the ability to induce apoptosis (cell death), halt the cell cycle, inhibit angiogenesis, and regulate inflammatory responses. They contain a variety of phytochemicals, such as flavonoids, tannins, terpenoids, alkaloids, and organosulfur compounds, which contribute to their anticancer effects. For example, Spondias mombin contains flavonoids that inhibit the formation of tumors, whereas Xanthosoma sagittifolium exhibits cytotoxic effects against leukemia cells. Additionally, Elaeis guineensis exhibits antioxidant properties that counteract oxidative stress, a crucial factor in cancer progression. This review highlights the significance of these plants in developing complementary cancer therapies that can be used alongside conventional treatments. By combining traditional knowledge with contemporary scientific methods, these medicinal plants have the potential to provide innovative approaches to cancer prevention and treatment, addressing the pressing demand for safer and more efficient therapeutic alternatives.

Patients with obstructive sleep apnea (OSA) and metabolic syndrome (MetS) have a higher prevalence and mortality rate of cardiovascular diseases, posing a significant burden on both individuals and society. Although the precise pathophysiological relationship between OSA and MetS remains unclear, their bidirectional interaction may create a harmful cycle of mutual reinforcement. This review explored the current treatment progress for OSA and MetS, including continuous positive airway pressure therapy, weight management, and metabolic surgeries. Studies indicate that while continuous positive airway pressure therapy effectively alleviates OSA symptoms, its impact on metabolic markers is limited, emphasizing the importance of long-term weight control. Metabolic surgeries, such as gastric bypass and sleeve gastrectomy, significantly reduce weight and directly improve metabolic abnormalities associated with MetS, such as insulin resistance and dyslipidemia, thereby lowering the risk of cardiovascular diseases. In contrast, mandibular advancement devices primarily improve symptoms of OSA and indirectly enhance metabolic function by improving sleep quality and reducing intermittent hypoxemia. Although mandibular advancement devices have a limited direct impact on metabolic parameters, they may offer potential benefits in lowering blood pressure and managing MetS. Understanding and breaking the cycle between OSA and MetS can significantly reduce the associated cardiovascular risks.
