Current practice and safety measures in epilepsy monitoring units in the Gulf Cooperation Council Countries: A cross-sectional study.

BACKGROUND: An increasing number of Epilepsy Monitoring Units (EMU) display various practices and safety protocols. EMU settings should meet clear, standardized safety protocols to avoid seizure adverse events (SAE). We aim to provide the foundational framework facilitating the establishment of unified evidence-based safety regulations to address the practices and safety measures implemented within the Gulf Cooperation Council (GCC). METHODS: In this cross-sectional study, EMU directors in the GCC were contacted directly by phone to personally complete an electronic 37-item questionnaire sent via text messages and email. From January 2021-December 2021. RESULTS: Seventeen EMUs from six GCC countries participated in the study. All EMU directors responded to the study. Twelve (70.6%) EMUs monitored adults and children, five (29.4%) monitored adults, and none monitored children only. The number of certified epileptologists in the EMUs ranged from one to eight per unit. Fifteen (88.2%) EMUs applied a continuous observation pattern, whereas two (11.8%) performed daytime only. The precautions most commonly used in the video Electroencephalogram (EEG) were seizure pads and bedside oxygen in 15 EMUs (88.2%). For invasive EEG, seizure pads were used in 9 EMUs (52.9%), %) and IV access in 8 EMUs (47.1%). The occurrence of adverse events varied among EMUs. The most common conditions were postictal psychosis 10 (58.8%), injuries 7 (41.2%), and status epilepticus 6 (35.3%). Falls were mainly related to missed seizures or delayed recognition by video monitors in 8 EMUs (47.1%). The extended EMU stay was because of an insufficient number of recorded seizures in 16 EMUs (94.1%), poor seizure lateralization and localization in 10 (58.8%), and re-introduction of AEDs in nine (52.9%). All EMUs had written acute seizure and status epilepticus management protocols. A postictal psychosis management protocol was available for 10 (58.8%). Medications were withdrawn before admission in 6 EMUs (35.3%). The specific medication withdrawal speed protocol upon admission was available in 7 EMUs (41.2%). Pre-admission withdrawal of medication demonstrated a shorter length of stay in both video and invasive EEG, which was statistically significant (ρ (15) = -.529, p =.029; ρ (7) = -.694, p =.038; respectively). CONCLUSION: The practice and safety regulations of EMUs in the GCC vary widely. Each EMU reported the occurrences of SAE and injuries. Precautions, protective measures, and management protocols must be reassessed to minimize the number of SAEs and increase the safety of the EMU.

Targeting NF-κB/COX-2 signaling by soyasaponin I alleviates diclofenac-induced gastric ulceration in male albino rats.

Gastric ulceration is a prevalent worldwide clinical presentation due to altered gastric defense mechanisms. Nonsteroidal anti-inflammatory drugs are one of the common causes of gastric ulcers mediated by the release of inflammatory mediators. The study aimed to investigate the potential protective effect of soyasaponin I (soya) against diclofenac (DIC)-induced gastric ulcer in rats and to highlight the underlying mechanisms. The experiment was conducted on 40 male Wistar albino rats, equally distributed into five groups: control, DIC-induced ulcer (9 mg/kg/d, orally, twice daily for 3 days), ulcer/soya-, ulcer/ranitidine-, and ulcer/soya/selective nuclear factor kappa B inhibitor (JSH-23)-treated groups. The doses of soya, ranitidine, and JSH were 20, 25, and 5 mg/kg/d, respectively, given orally. Gastric specimens were prepared for gene and histological study and for biochemical analysis of gastric prostaglandin E2 (PGE2), oxidative markers, and inflammatory cytokines. The gastric samples were formalin-fixed, paraffin-embedded, and subjected to hematoxylin and eosin (H&E), PAS staining, and immunohistochemical assay for identification of nuclear factor kappa B (NF-κB), cyclooxygenase-2 (COX-2), and proliferation marker (Ki67) expressions. The findings revealed decreased gastric PGE2 and altered inflammatory and oxidative markers in the ulcer model group. The H&E staining showed mucosal injury characterized by mucosal surface defects and inflammatory cell infiltrations. The polymerase chain reaction (PCR) and immunohistochemistry demonstrated an upregulation of NF-κB and COX-2 expression at gene/protein levels; meanwhile, Ki67 downregulation. The soya-treated group showed maintained biochemical, histological, and PCR findings comparable to the ranitidine-treated group. The JSH-23-treated group still showed partial gastric protection with biochemical and immunohistochemical changes. Soyasaponin I ameliorated DIC-induced gastric ulcers by targeting the COX-2 activity through modulation of NF-κB signaling.

Stroke intervention and pharmacotherapy guidelines: Knowledge-to-practice translation gaps among the emergency resident physicians in Riyadh, Saudi Arabia.

Translating the updated medical guidelines into routine clinical practice is an important initiative to improve the population's health and decrease disease outcomes. A cross-sectional survey-based study was conducted in Riyadh City, Saudi Arabia, to evaluate the knowledge and degree of application (practice) of the stroke management guidelines among emergency resident physicians. An interview-based self-administered questionnaire was used to survey the emergency resident doctors in Riyadh hospitals from May 2019 to January 2020. Of 129 participants, 78 valid, complete responses were obtained (60.5% response rate). Descriptive statistics, principle component, and correlation analyses were used. Most resident doctors were men(69.4%) with a mean age of 28.4±3.37 years. More than 60% of the residents were satisfied with their knowledge of the stroke guidelines; meanwhile, 46.2% were satisfied with their application of the guidelines. Both Knowledge and practice compliance components were significantly and positively correlated. Also, both components were significantly correlated with being updated, aware of, and strictly following these guidelines. The mini-test challenge showed a negative result with a mean knowledge score of 1.03±0.88. Even though the majority of participants utilized different tools of education and were aware of the American Stroke Association Guidelines. It was concluded that a considerable gap in the residents' knowledge regarding the current stroke management guidelines was present in Saudi hospitals. Also, it was reflected on their actual implementation and application into clinical practice. Continuous medical education, training, and follow-up of the emergency resident doctors, administered as a part of the government health programs, are crucial to improve the health care delivery for acute stroke patients.

Nitric oxide is involved in ibuprofen preemptive analgesic effect in the plantar incisional model of postsurgical pain in mice.

Control of postoperative pain is far from satisfactory. Yet, non-steroidal anti-inflammatory drugs (NSAIDs) remain an important choice. The production of nitric oxide (NO), which plays an important role in the development and maintenance of inflammatory hyperalgesia, is inhibited by NSAIDs. Monoamines also play a key role in the modulation of nociception. The aim of the present work is to study the involvement of NO and monoamines in the antinociceptive mechanism of ibuprofen in postsurgical pain in mice. Surgical incision resulted in mechanical allodynia and increased spinal NO levels. The nitric oxide synthase inhibitor l-NAME (50mg/kg), administered intraperitoneally (i.p.), 30min before the incision decreased the development of postsurgical mechanical allodynia and reduced spinal NO levels. Ibuprofen (100 and 300mg/kg, i.p.), administered 30min before the incision, dose-dependently decreased both spinal NO levels and the development of mechanical allodynia. Administration of ibuprofen (100mg/kg i.p.), 20min following surgery, did not significantly reduce spinal NO level and resulted in a smaller antiallodynic effect. l-Arginine (600mg/kg i.p.), administered 20min before ibuprofen administration, restored both spinal NO level and mechanical allodynia in ibuprofen-treated mice. The selective alpha-2 adrenoceptor blocker yohimbine (4mg/kg i.p.), administered 30min before ibuprofen, also blocked ibuprofen effect on both mechanical allodynia and spinal NO level. These results suggest that inhibition of NO synthesis is involved in the analgesic activity of ibuprofen in post-surgical pain. Alpha-2 adrenoceptors are also involved in the analgesic activity of ibuprofen and NO may be involved in this mechanism.
