Monkeypox is a self-limiting zoonotic disease caused by the monkeypox virus belonging to the genus of orthopox viruses. Initially considered an ‘African disease’, this infection has crossed the boundaries to affect other continents and it has raised tremendous concerns among the general public as well as the medical fraternity all over the world, particularly because of the lack of specific vaccinations and drugs for the management of the illness. Epidemiological evaluation of the current infection has reported that it is mainly transmitted through sexual contact in bisexual men, mostly whites, and in those with pre-existing human immunodeficiency virus infection. The most common presentations were skin rash, anogenital lesions, or mucosal lesions along with systemic symptoms. It has been established that the vaccines and drugs approved for the management of smallpox could be used for the management of the current monkeypox outbreak. Vaccinia Immune Globulin (VIG) and vaccines like JYNNEOS and ACAM2000 and antiviral drugs like tecovirimat, cidofovir (CDV), and brincidofovir are being considered for those patients with serious diseases. It is imperative for physicians to understand the pharmacological aspects of these drugs for delivering better care to patients with monkeypox, which is eventually essential for the containment of this infection. This review covers updates on vaccines as well as drugs for the prevention and management of monkeypox.

A 26-year-old Malaysian woman (childbearing age) attended a private primary care clinic with a known case of gastroesophageal reflux disease (GERD) and complained of persistent nausea and a few episodes of vomiting. She had no known drug allergy, no surgical history, no hospitalization in the last two years, was a non-smoker, and no history of drug or alcohol abuse. The patient was prescribed Tab metoclopramide 10 mg TDS and Tab ranitidine 150 mg BD for five days. About 30 min after oral administration of both medicines, her eyes rolled involuntary upward, leading to lateral deviation of the eyes, and mouth jaws clenched as if “dislocated jaws.” The patient was immediately brought into an emergency department (ED) of a public tertiary care hospital. A drug challenge test was done which resulted in the withdrawal of metoclopramide. The accompanied sister later disclosed that the patient had taken metoclopramide and ranitidine from a private clinic earlier in the day. The patient self-assumed to have a sudden seizure, due to excessive hot weather and dehydration. A slow intravenous infusion of 50 mg/mL diphenhydramine hydrochloride in 0.9% w/v NaCl 100 mL was administered stat. Consequently, the symptoms vanished after approximately 30 min of the therapy, devoid of relapse. The patient was discharged from ED post 8 hours of monitoring with complete recovery. Physicians frequently prescribe metoclopramide to treat nausea and vomiting, which may cause adverse drug reaction of acute dystonic oculogyric crisis (OGC). Due to its unwanted and unpredictable extrapyramidal symptoms, metoclopramide should be prescribed and dispensed with caution. Thorough history taking at ED is imperative for correct early diagnosis and treatment, as metoclopramide-induced dystonic OGC has a high probability of confusion with other causes of dystonia such as conversion and seizures, encephalitis, tetanus, and hypercalcemic tetany.

Recent research has shown a strong correlation between gut dysbiosis and Alzheimer’s disease (AD). The purpose of this review is to investigate the relationship between gut dysbiosis, immune system activation, and the onset of AD and to examine current breakthroughs in microbiota-targeted AD therapeutics. A review of scientific literature was conducted to assess the correlation between gut dysbiosis and AD and the various factors associated. Gut dysbiosis produces an increase in harmful substances, such as bacterial amyloids, which makes the gut barrier and blood-brain barrier more permeable. This leads to the stimulation of immunological responses and an increase in cytokines such as interleukin-1β (IL-1β). As a result, gut dysbiosis accelerates the progression of AD. The review highlights the connection between gut dysbiosis and AD and the potential for microbiota-targeted therapies in AD treatment. Pictorial Abstract

Objective To evaluate the link between phenotypic traits, antimicrobial resistance, and biofilm-producing capacity of urinary isolates of Citrobacter freundii (C. freundii). Methods Both pan-antibiotic-susceptible and -resistant C. freundii isolates (n = 120) obtained from laboratory-confirmed urinary tract infections were analyzed for their link between antimicrobial resistance, phenotypic characteristics, and biofilm production. Results Of the total C. freundii isolates (n = 120), 30% (37/120) of them formed large colonies. Among the total large colonies produced (n = 37), they were present in 21.62%, 10.81%, 13.5%, 16.2%, 21.62%, and 16.21% in the control group, CIP-group, FOS-group, COT-group, Gent-group, and ESBL groups, respectively. Compared to the pan-susceptible isolates, the occurrence of large-sized-colony-forming strains was relatively reduced in most of the drug-resistant groups. The overall distribution of mucoid colonies produced (n = 54) includes 9.25%, 18.51%, 16.66%, 18.51%, 20.3%, and 16.66% in the control group, CIP-group, FOS-group, COT-group, Gent-group, and ESBL groups, respectively. Of the total isolates that produced biofilm (n = 51), 11.76% of isolates showed biofilm formation in the control group. Alternatively, the rate was found to be 15.68%, 11.76%, 25.49%, 19.6%, and 15.68% in the CIP-group, FOS-group, SXT-group, Gen-group, and ESBL-groups, respectively. Conclusion This study correlates the association between phenotypic characteristics, antimicrobial resistance, and biofilm production, the three main characteristics of C. freundii.

Objective To evaluate the effect of p-coumaric acid (p-CA) on haloperidol-induced catalepsy in Swiss albino male mice. Methods To induce catalepsy, haloperidol (1 mg/kg i.p.) was administered for 21 consecutive days. p-CA (50, 75, and 100 mg/kg, PO) was administered 30 min before haloperidol injection for 21 consecutive days. For catalepsy, locomotor activity and motor coordination scores were recorded on the 17, 14, and 21 days of drug treatment, while the gait analysis score was recorded on day 21. After behavioral testing, animals were sacrificed, and various biochemical and histopathology tests of the brain were conducted. Dopamine, malondialdehyde, reduced glutathione (GSH), superoxide dismutase (SOD), and catalase activity were examined in the brain. Results Chronic administration of haloperidol significantly increased catalepsy in mice. It also produced hypolocomotion, motor coordination, and gait disturbance in mice. p-CA significantly inhibited haloperidol-induced catalepsy. Haloperidol significantly increased malondialdehyde levels in the brain. While dopamine levels in the brain dropped along with GSH, SOD, and catalase activity levels, which also had an impact on the histology of the brain. p-CA significantly reduced haloperidol-induced increases in brain oxidative stress, dopamine levels in the brain, and brain histology in mice. Discussion p-CA significantly reduced haloperidol-induced catalepsy, possibly through reducing oxidative stress and increasing brain dopamine levels. It can be a good candidate drug for extrapyramidal symptoms in Parkinson’s disease and adjuvant therapy with antipsychotic drugs.

The coexistence of humans and animals has existed for centuries. Over the past decade, animal research has played a critical role in drug development and discovery. More and more diverse animals, including transgenic animals, are used in basic research than in applied research. Transgenic animals are generated using molecular genetic techniques to add functional genes, alter gene products, delete genes, insert reporter genes into regulatory sequences, replace or repair genes, and make changes in gene expression. These genetically engineered animals are unique tools for studying a wide range of biomedical issues, allowing the exhibition of specific genetic alterations in various biological systems. Over the past two decades, transgenic animal models have played a critical role in improving our understanding of gene regulation and function in biological systems and human disease. This review article aims to highlight the role of transgenic animals in pharmacological, toxicological, and environmental research. The review accounts for various types of transgenic animals and their appropriateness in multiple types of studies.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has spread rapidly and diffused to more than 180 countries at varying severities. This pandemic has accounted for increased mortality and morbidity in developed as well as developing nations. The WHO has announced that there is a persistent need for the evaluation of the COVID-19 vaccine effectiveness (VE) against major outcomes, which include severe diseases, symptomatic COVID-19, and mortalities related to COVID-19. Therefore, mass vaccination programs using vaccines of high effectiveness are among the strategies that have been used by governments worldwide to impede the COVID-19 pandemic transmission. In this regard, massive efforts were made by governments, scientists, biomedical researchers, and healthcare professionals leading to the successful development of various vaccines to bring this pandemic under control. This editorial aims to shed light on the epidemiological status of COVID-19 variants, namely, Delta, Omicron, and Deltacron variants as well as discuss the effectiveness of the currently available COVID-19 vaccines.

Tapinarof is a novel topical formulation approved recently, in May 2022, by the United States Food and Drug Administration to treat plaque psoriasis. Existing topical therapies for psoriasis are limited by systemic and local adverse effects, medication cost and repeated administration, thus significantly hampering the compliance of patients to therapy. These limitations can be resolved by tapinarof owing to its better efficacy and favourable safety profile in psoriasis management. Tapinarof was developed with a unique mechanism targeting the aryl hydrocarbon receptor (AhR) involved in inflammation and modulation of skin barrier integrity in inflammatory dermatological disorders such as psoriasis and atopic dermatitis. The efficacy and safety outcomes of tapinarof in psoriasis were justified through the two pivotal clinical trials, namely, PSOARING 1 and PSOARING 2. The common adverse effects observed with tapinarof are folliculitis, contact dermatitis and headache. The literature search was conducted for efficacy and safety of tapinarof in the electronic databases of PubMed and Cochrane using a combination of keywords such as tapinarof, psoriasis and AhR. This review will delineate the molecular mechanisms underlying the action of tapinarof and also summarise the trial data supporting the claim that tapinarof is replacing the existing standard of care in psoriasis management.

Phosphodiesterase type 5 (PDE5) is a cyclic GMP (cGMP) specific protein. It hydrolyzes the phosphodiesterase linkage and catalyzes the conversion of cGMP to 5’ GMP, which controls different physiological activities of the body. PDE5 is associated with biomedical conditions like neurological disorders, pulmonary arterial hypertension, cardiomyopathy, cancer, erectile dysfunction, and lower urinary tract syndrome. Inhibition of PDE5 has now been proven pharmaceutically effective in a variety of therapeutic conditions. Avanafil, tadalafil, sildenafil, and vardenafil are the most commonly used PDE5 inhibitors (PDE5i) today which are often used for the management of erectile dysfunction, lower urinary tract syndromes, malignancy, and pulmonary arterial hypertension. However, these synthetic PDE5i come with a slew of negative effects. Some of the most common side effects include mild headaches, flushing, dyspepsia, altered color vision, back discomfort, priapism, melanoma, hypotension and dizziness, non-arteritic anterior ischemic optic neuropathy (NAION), and hearing loss. In light of the potential negative effects of this class of medications, there is a lot of room for new, selective PDE5 inhibitors to be discovered. We have found 25 plant botanical compounds effectively inhibiting PDE5 which might be useful in treating a variety of disorders with minimal or no adverse effects.
