Methanol is a widely used industrial and household alcohol that poses significant health risks upon exposure. Despite its extensive use, methanol poisoning remains a critical public health concern globally, often resulting from accidental or intentional ingestion and outbreaks linked to contaminated beverages. Methanol toxicity stems from its metabolic conversion to formaldehyde and formic acid, leading to severe metabolic acidosis and multiorgan damage, including profound CNS effects and visual impairments. Epidemiological data underscore the widespread impact of methanol poisoning, with alarming case fatality rates reported in various countries. Comprehensive prevention and effective management strategies are urgently needed to address the significant morbidity and mortality associated with methanol poisoning. The clinical manifestations of methanol toxicity vary between adult and pediatric populations and between acute and chronic exposure. Adults typically present with gastrointestinal and neurological symptoms, whereas pediatric patients often exhibit more severe outcomes due to differences in metabolism and body weight. The diagnosis of methanol poisoning involves a combination of clinical evaluation, laboratory testing, and advanced diagnostic techniques. The identification of metabolic acidosis, elevated anion and osmolal gaps, and confirmation through methanol and formate levels are critical for accurate diagnosis. Timely intervention is crucial, and the management of methanol poisoning includes securing the airway, breathing, and circulation; addressing metabolic acidosis with sodium bicarbonate; administering antidotes such as fomepizole or ethanol; and administering hemodialysis, which plays a pivotal role in eliminating methanol and its toxic metabolites, especially in severe cases. The complexity of methanol poisoning necessitates a comprehensive approach encompassing early recognition, prompt intervention, and coordinated care among healthcare providers. Increased awareness, effective prevention strategies, and timely treatment protocols are essential to mitigate severe health consequences and improve patient survival and recovery.

Calcium channel blockers (CCBs) are widely prescribed medications for various clinical indications in adults and children. They are available in both immediate and long-acting formulations and are generally classified into dihydropyridines and nondihydropyridines, with nondihydropyridines having more cardioselectivity. CCB toxicity is common given the widespread use which leads to serious adverse clinical outcomes, especially in children. Severe CCB toxicities may present with life-threatening bradycardia, hypotension, hyperglycemia, and renal insufficiency. Dihydropyridine toxicity, however, may present with reflex tachycardia instead of bradycardia. Initial patient evaluation and assessment are crucial to identify the severity of CCB toxicity and design the best management strategy. There are different strategies to overcome CCB toxicity that requires precise dosing and close monitoring in various patient populations. These strategies may include large volumes of IV fluids, calcium salts, high insulin euglycemia therapy (HIET), and vasopressors. We hereby summarize the evidence behind the management of CCB toxicity and present a practical guide for clinicians to overcome this common drug toxicity.

Hajj is the largest mass gathering worldwide that takes place every year in Makkah, Saudi Arabia. This paper aims to provide a comprehensive guide and expectations for delivering and optimizing clinical pharmacy services during one of the largest mass gatherings in the world, Hajj pilgrimage METHODS: A task force initiated and included members of clinical pharmacists who previously participated in delivering clinical pharmacy services during the Hajj pilgrimage, members of the Saudi Society of Clinical Pharmacy (SSCP), and policymakers from different sectors and representatives from pharmaceutical care of the Ministry of Health (MOH). The members established an expert task force to conceptualize and draft the proposed suggestions highlighting the roles and responsibilities of clinical pharmacists during the annual Hajj season. The task force determined the following key domains 1) pharmaceutical care (administration and strategic plan, resources, formulary management); 2) pharmacists' activities (clinical pharmacy services and documentation, professional training and development, and staff credentials, and qualifications); 3) challenges and proposed solutions. The task force was divided into groups to draft each domain and provide suggested statements and insights for each section. Finally, the group members of the task force issued 15 opinion statements. Mass gatherings such as Hajj pilgrimage, represent a unique opportunity to demonstrate the value of pharmacists in advancing health care delivery within a multidisciplinary team. These suggestions and insights could guide the implementation of clinical pharmacy services in acute settings during mass gatherings (Hajj). Future studies should focus on assessing the applicability and the impact of the provided suggestions.

During the COVID-19 pandemic, countries around the world implemented various interventions to manage the spread of respiratory illnesses, including influenza. However, there is a lack of studies that have assessed the influence of COVID-19 on influenza prevalence in Saudi Arabia. In this study, we aimed to evaluate the prevalence of positive influenza cases before and during the COVID-19 pandemic in relation to the mitigation measures and policy initiatives in Saudi Arabia. A multicenter, time-series cross-sectional study was conducted to evaluate influenza prevalence before and during the COVID-19 pandemic between 01/01/2017 and 31/12/2021. This study included all patients who were screened for influenza infection at healthcare facilities across Saudi Arabia using polymerase chain reaction (PCR). The primary outcome was to determine the prevalence of influenza infections before and during the COVID-19 pandemic, while the secondary outcome was to describe the demographic data and comorbidities of the included patients in both periods. During the study period, 5238 cases were identified based on a positive PCR result for influenza virus. The yearly number of influenza cases in the pre-COVID-19 period was 1123 (2.03 %), 1075 (1.63 %), and 1883 (2.20 %) cases in 2017, 2018, and 2019, respectively. On the other hand, the number of cases during the COVID-19 pandemic was 417 (0.63 %) and 740 (1.27 %) in 2020 and 2021, respectively, with a comparable number of performed tests. Patients infected with the influenza virus between 2020 and 2021 were older than patients who were infected before the COVID-19 pandemic. The study found a lower number of influenza cases during the COVID-19 pandemic, with no clear peak during November and December 2020 and 2021.

Background: Hyperuricemia has been linked to various adverse clinical outcomes. Data on the clinical outcomes and the relationship between hyperuricemia and sepsis remain limited. The aim of this study was to evaluate the impact of hyperuricemia on clinical outcomes in sepsis patients and to identify whether it can predict the mortality in this patient population. Methods: This was a retrospective cohort study of adult patients with sepsis admitted to the intensive care unit (ICU) from 1 January 2021 to 31 December 2023. The patients were divided into hyperuricemia and non-hyperuricemia groups. Hyperuricemia was defined as a serum uric acid level > 416.4 µmol/L (7.0 mg/dL) in males or >357.0 µmol/L (6.0 mg/dL) in females based on the first serum uric acid reading within 24 h of ICU admission. The primary outcome of this study was ICU mortality. Secondary outcomes included in-hospital mortality, progression to septic shock, and ICU and hospital lengths of stay (LOSs). Results: A total of 599 patients were included in the study. Among these, 303 were in hyperuricemia group, while 296 were in the non-hyperuricemia group. The incidence of ICU and in-hospital mortality was higher in the hyperuricemia group compared to the non-hyperuricemia group (26.7% vs. 18.9% (p < 0.001) and 34.7% vs. 19.3% (p < 0.001), respectively). After adjusting for cofounders, hyperuricemia was not a predictor of ICU mortality (OR 1.52, 95% CI 0.95–2.43, p = 0.083). Most secondary outcomes were similar between the groups. However, the hyperuricemia group had a higher incidence of progression to septic shock (67.3% vs. 50.7%, p < 0.001), and hospital LOS was significantly longer in the hyperuricemia group (384 vs. 264 h, p = 0.004). Conclusions: Our findings demonstrated that hyperuricemia in sepsis patients was associated with worse clinical outcomes such as higher ICU and hospital mortality. Moreover, there was a higher incidence of septic shock progression and longer hospital LOS. The other outcomes were not statistically significantly different. Further prospective research is warranted to confirm these findings.

Aberrant gene expression is often linked to the progression of various cancers, making the targeting of oncogene transcriptional activation a potential strategy to control tumor growth and development. The RET proto-oncogene’s gain-of-function mutation is a major cause of medullary thyroid carcinoma (MTC), which is part of multiple endocrine neoplasia type 2 (MEN2) syndrome. In this study, we used a cell-based bioluminescence reporter system driven by the RET promoter to screen for small molecules that potentially suppress the RET gene transcription. We identified adefovir dipivoxil as a transcriptional inhibitor of the RET gene, which suppressed endogenous RET protein expression in MTC TT cells. Adefovir dipivoxil also interfered with STAT3 phosphorylation and showed high affinity to bind to STAT3. Additionally, it inhibited RET-dependent TT cell proliferation and increased apoptosis. These results demonstrate the potential of cell-based screening assays in identifying transcriptional inhibitors for other oncogenes.
