Osteoporosis is a major global health problem. The increase in the incidence of osteoporosis in the elderly poses a challenge to treat and also results in an economic burden for the nation. Osteoporosis has been given more importance in females, and there is an urgent need to address this disease in males. Various drugs, such as nitrogen-containing bisphosphonates, RANK ligand inhibitors, parathormones, and alendronate, have been used for effective treatment of osteoporosis. Alendronate (alendronic acid), a nitrogen-containing bisphosphonate that inhibits bone resorption by osteoclasts, was synthesized during the 1970s. In the present review, we discuss the pharmacokinetics, mechanism of action, adverse effects, contraindications, and toxicity monitoring of alendronate. The drug may be effectively used for the treatment of male osteoporosis in order to increase bone mineral density and prevent fractures.

: Gut microbiota refers to the population of trillions of microorganisms present in the human intestine. The gut microbiota in the gastrointestinal system is important for an individual’s good health and well-being. The possibility of an intrauterine colonization of the placenta further suggests that the fetal environment before birth may also affect early microbiome development. Various factors influence the gut microbiota. Dysbiosis of microbiota may be associated with various diseases. Insulin regulates blood glucose levels, and disruption of the insulin signaling pathway results in insulin resistance. Insulin resistance or hyperinsulinemia is a pathological state in which the insulin-responsive cells have a diminished response to the hormone compared to normal physiological responses, resulting in reduced glucose uptake by the tissue cells. Insulin resistance is an important cause of type 2 diabetes mellitus. While there are various factors responsible for the etiology of insulin resistance, dysbiosis of gut microbiota may be an important contributing cause for metabolic disturbances. We discuss the mechanisms in skeletal muscles, adipose tissue, liver, and intestine by which insulin resistance can occur due to gut microbiota's metabolites. A better understanding of gut microbiota may help in the effective treatment of type 2 diabetes mellitus and metabolic syndrome.

This research aims to establish the prevalence of imposter syndrome among Sultan Qaboos University (SQU) undergraduate students while assessing its association with depression symptoms and anxiety symptoms. A cross-sectional design recruited 504 undergraduate students selected through stratified random sampling. Data collection employed the Clance Imposter Phenomenon Scale (CIPS), the Patient Health Questionnaire-9 (PHQ-9), and the Generalized Anxiety Disorder-7 (GAD-7). Data analysis included Pearson’s correlation, chi-square tests, and logistic regression analyses. In total, 56% of participants had imposter syndrome. The CIPS scores showed a moderate relationship with depression (r = 0.486, p < 0.001) and anxiety (r = 0.472, p < 0.001). Students who experienced imposter syndrome showed a higher probability of developing depressive symptoms (χ² = 45.63, p < 0.001, OR = 3.49) and anxiety symptoms (χ² = 32.96, p < 0.001, OR = 2.86). The logistic regression analysis showed that depression (B = 0.096, p < 0.001) and anxiety (B = 0.075, p = 0.003) acted as significant predictors for imposter syndrome. This study reveals a strong link between imposterism, depression, and anxiety among students. This highlights the need for university counseling programs to address imposter feelings and the role of clinical psychology in managing this phenomenon in academic and clinical settings.

Small endogenous non-coding RNA molecules known as micro-ribonucleic acids (miRNAs) control post-transcriptional gene regulation. A change in miRNA expression is related to various diseases, including bone tumors. Benign bone tumors are categorized based on matrix production and predominant cell type. Osteochondromas and giant cell tumors are among the most common bone tumors. Interestingly, miRNAs can function as either tumor suppressor genes or oncogenes, thereby determining the fate of a tumor. In the present review, we discuss various bone tumors with regard to their prognosis, pathogenesis, and diagnosis. The association between miRNAs and bone tumors, such as osteosarcoma, Ewing’s sarcoma, chondrosarcoma, and giant-cell tumors, is also discussed. Moreover, miRNA may play an important role in tumor proliferation, growth, and metastasis. Knowledge of the dysregulation, amplification, and deletion of miRNA can be beneficial for the treatment of various bone cancers. The miRNAs could be beneficial for prognosis, treatment, future drug design, and treatment of resistant cases of bone cancer.

Uveal melanoma (UM) is the most common primary intraocular malignancy in adults and commonly occurs in the Caucasian population. The malignancy involves the uvea of the eye, which includes the iris, ciliary body, and choroid. The etiology of UM is still not well understood, but age is a risk factor. Symptoms include blurred vision, redness of the eye, floaters, dark spots, a change in the size of the pupil, and loss of vision. The location, shape, and size of the tumor are important for therapeutic purposes. Treating metastasis is always a challenge in UM cases. In cases of lung metastasis, the survival rate decreases. Treatment includes surgery, laser therapy, immunotherapy, hormone therapy, and chemotherapy. Recently, in 2022, the United States Food and Drug Administration (FDA) approved the drug tebentafusp. Tebentafusp was developed to target the most common HLA complex in humans. The present review discusses the indications for the use of a new drug tebentafusp, its mechanism of action, dose, pharmacokinetics, results of clinical trials conducted, and adverse effects like cytokine release syndrome. Hence, tebentafusp is the first T cell receptor (TCR) therapeutic drug that could be considered for the treatment of UM.

Obesity is a growing global health challenge, necessitating effective treatment options beyond lifestyle interventions. This narrative review explores established and emerging pharmacotherapies for weight management, including parenteral agents like Liraglutide, Semaglutide, Setmelanotide, and Tirzepatide, as well as peroral medications such as Phentermine, Phentermine/Topiramate, Bupropion/Naltrexone, Orlistat, and Metformin. Newer treatments like Cagrilintide and Bimagrumab show promise for enhancing weight loss outcomes. Parenteral GLP-1 receptor agonists demonstrate superior efficacy compared to traditional peroral medications, with gastrointestinal side effects being the most common. Artificial intelligence presents intriguing opportunities to enhance weight loss strategies; however, its integration into clinical practice remains investigational and requires rigorous clinical validation. While current anti-obesity medications deliver significant benefits, future research must determine the efficacy, safety, and cost-effectiveness of AI-driven approaches. This includes exploring how AI can complement combination therapies and tailor personalized interventions, thereby grounding its potential benefits in robust clinical evidence. Future directions will focus on integrating AI into clinical trials to refine and personalize obesity management strategies.
