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.

Genetic polymorphisms of CYP2D6 and CYP2C19 affect both the effectiveness and the occurrence of side effects of many antidepressants. By drug-drug-gene interactions (also referred to as phenoconversion), the phenotype of the patient can be changed. Both pharmacogenetic testing, drug-drug, and drug-drug-gene interaction checks are essential to individualize the dose of the antidepressant or start an alternative drug in accordance with the pharmacogenetic guidelines. The aim of this study was to analyze the frequency of divergent phenotypes (i.e. divergent from the common phenotypes considered normal), of phenoconversion (a genotype–phenotype mismatch), and of actionable genotypes (genotypes where a prescribing change may be indicated) in psychiatric inpatients with a depressive disorder.

Genotyping of CYP2D6 and CYP2C19 was performed in 104 patients 18 years of age or older who received inpatient treatment in a German psychiatric university hospital for a depressive disorder. Representation of the frequencies of divergent phenotypes, of phenoconversion, and of actionable genotypes were analyzed.

A divergent phenotype in one or both CYP enzymes was seen in 83.5% of the patients. The rate of CYP2D6 poor metabolizers increased by 142.4% (from 5.9% to 14.3%, p = 0.013) at admission and by 183.1% (from 5.9% to 16.7%, p = 0.004) at discharge because of phenoconversion. At discharge, 22% of the patients (n = 104) received an antidepressant with a dosing recommendation based on their CYP2D6 phenotype and 15.4% on their CYP2C19 phenotype. When considering phenoconversion, the rate increased by 17.4 to 26.0% (p = 0.221) for patients with the CYP2D6 genotype.

The clinical relevance of the results of the study is that phenotype conversion is common in patients treated for depression with medication. The discrepancy between the clinically observed phenotype and the phenotype expected based on the patient genotype underscores the need for greater consideration of both genetic and nongenetic factors.

Albumin is a major prognostic factor for patients with advanced liver disease, dependent on its concentration and biological activity. This study aimed to improve the method of active albumin detection and elucidate its predictive validity of albumin activity across hepatic disease progression and etiology.

This study synthesized a novel ratiometric fluorescent probe with an improved structure of 2′-FBPBN. The technique was used to detect native human albumin (HA) activity in 244 patients with hepatitis B cirrhosis (LC) and 66 patients with hepatocellular carcinoma (HCC). Clinical and laboratory data were also collected.

Patients with LC and HCC were divided into normal albumin and low albumin (LA) groups. The median levels of albumin and HA activity in LC patients were 41.44 g/L and 51.85%, 28.51 g/L and 53.89%, respectively, while in HCC patients, they were 43.19 g/L and 33.69%, 30.77 g/L and 43.63%, respectively. The levels of total bilirubin, prothrombin time, international normalized ratio, native HA activity, Child-Pugh score, model for end-stage liver disease score, and model for end-stage liver disease-Na score were significantly higher in the LA groups, while the levels of platelet, cholesterol, and cholinesterase were lower compared to the normal albumin group (P < 0.05). The LA groups were more likely to suffer from hepatic encephalopathy and ascites. Patients with normal active HA had significantly higher survival rates than those with low active HA.

Native HA activity may outperform albumin as a prognostic indicator for assessing the severity of liver disease.

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.

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.

Radiation injury poses a serious threat to human health, causing complex and multifaceted damage to cells and tissues. Such injury can be caused by various factors, including nuclear accidents, medical radiation therapy, and space travel. Currently, finding effective treatment methods and drugs to mitigate the harmful effects of radiation injury on the human body is a crucial research direction. This study aimed to explore the protective effects and mechanisms of Licochalcone B (Lico B) on radiation-induced cell damage and radiation-induced mortality in mice.

HaCaT cells, THP-1 cells, and HAEC cells were irradiated with a 10 Gray (Gy) dose of X-rays, while RAW 264.7 cells were irradiated with a 10 Gy dose of γ-rays. The cells were pre-treated with Lico B for 2 h before irradiation, and samples were collected 2 h after irradiation. Cell proliferation viability, oxidative stress levels, DNA damage, expression levels of inflammatory factors, matrix metalloproteinases, guanylate cyclase, and iron death-related factors were measured. C57BL/6 mice were exposed to total-body irradiation with a dose of 8 Gy or a combined dose of 6 Gy + 8 Gy of γ-rays to induce radiation injury. Lico B was injected intraperitoneally one day before irradiation and then administered for two consecutive days, with continuous observation for 20 days.

Mechanistically, Lico B significantly improved antioxidant levels, reduced DNA damage, and lowered the expression of inflammatory factors in HaCaT, THP-1, HAEC, and RAW 264.7 cells. Therapeutically, Lico B increased cell proliferation capacity and significantly extended the survival time of irradiated mice, demonstrating a strong radioprotective effect.

Lico B exhibits significant radioprotective effects and may serve as a potential radioprotective agent.

Experimental models using 2/3 partial hepatectomy or chemical injury have helped identify the pathways associated with liver regeneration (LR). Several microRNAs (miRNAs) have been identified as modulators of LR, but the molecular mechanisms underlying their activity are still unclear. Given the development of new therapies targeting miRNAs, this is an important question to address. This review discusses recent studies exploring the molecular mechanisms of miRNA-dependent regulation of LR. In particular, the finding that circ-RBM23 promotes LR by sequestering cytoplasmic miRNA139-5p has furthered the understanding of the molecular mechanisms underlying circRNA activity. Interestingly, although miRNAs are generally considered negative regulators of their target mRNAs, miRNAs182-5p promotes LR by upregulating Cyp7a. Furthermore, mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) were shown to enhance LR after 2/3 partial hepatectomy by releasing miRNAs that inhibit gene expression to promote an anti-inflammatory response or miRNA-regulatory factors. Since the administration of MSCs-EVs has no hepatotoxic side effects, this may represent a therapeutic strategy to promote LR. miRNAs also mediate LR after chemical injury. This is the case for miR194 and miR21, whose downregulation activates pro-regeneration pathways to ameliorate acetaminophen-induced liver injury. In addition, the downregulation of miR21 has been shown to improve autophagy and haemostasis after acetaminophen overdose. Although further studies are needed to improve their efficacy as therapeutics, the evidence gathered in this review has led to a better understanding of the molecular mechanisms associated with the control of LR by miRNAs.
