Background Helicobacter pylori ( H. pylori ) causes chronic infection in more than half of the population worldwide. Accumulating body of evidence indicates the possible role of H. Pylori infection in extra-intestinal health problems, including epilepsy. This study aims to investigate the efficacy of treating H. pylori infection on seizure frequency among children with drug-resistant idiopathic generalized epilepsy (IGE). Methods A parallel, two-arm, open-label, randomized controlled trial was conducted on 126 children with drug-resistant IGE and positive H. pylori stool antigen test who were randomly assigned to study and comparison groups in 1.2:1 ratio. Only the study group received H. pylori eradication therapy (esomeprazole, amoxicillin, and clarithromycin) for two weeks. The primary outcome was seizure improvement (≥ 50% seizure frequency reduction compared with baseline) after 2.5 months. Secondary outcomes were occurrence of status epilepticus, escalation of antiseizure medication (ASMs), and adverse effects. Outcomes between the two groups were compared using Chi-square/Fisher exact tests on an intention-to-treat principle. Logistic regression analysis was performed to investigate possible effects of baseline variables on primary outcome. Results Seizure improvement occurred in 23 (33%) children in the study group compared with seven (12%) children in the comparison group (Risk ratio [RR] 2.7, 95% confidence interval [CI]: 1.3–5.9; p 0.006). The study group had lower occurrence of status epilepticus (2.9% vs. 14%; RR 0.21, 95%CI: 0.05–0.93; p 0.042) and lesser need for ASMs escalation (4.4% vs. 19.3%; RR 0.23, 95%CI: 0.07–0.77; p 0.010). Adverse effects were more frequent among subjects in the study group, including nausea (15.9% vs. 10.5%) vomiting (8.7% vs. 3.5%), diarrhea (11.6% vs. 5.3%), and skin rash (4.4% vs. 1.8%), but the differences were not statistically significant ( p  > 0.05). None of baseline participants’ variables was significantly associated with the primary outcome. Conclusion Treating H. pylori infection may improve seizure control in children with drug-resistant IGE, but further studies are warranted to confirm our findings and explore mechanisms behind seizure improvement following H. pylori eradication therapy.

Background Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with limited treatment options yielding poor outcomes. This study aimed to evaluate the real-world clinical characteristics, treatment patterns, and outcomes of patients with locally advanced unresectable and de-novo metastatic PDAC in Saudi Arabia, providing regional data to compare with international benchmarks. Methods This is a retrospective, multicentre study involving 350 patients diagnosed with unresectable locally advanced or de-novo metastatic PDAC between January 2015 and November 2023. Data were collected from 10 oncology centers across Saudi Arabia. Results The median age at diagnosis was 60 years, with 63% of patients presenting with multiple metastatic sites, primarily in the liver (66.3%). FOLFIRINOX was the most common first-line treatment (55.1%), followed by gemcitabine plus nab-paclitaxel (15.1%). The median PFS for first-line treatment was 5.3 months, with FOLFIRINOX achieving the longest PFS (6.5 months). The median OS was 10.34 months for the entire cohort, with better survival outcomes observed in patients receiving FOLFIRINOX (12.3 months). Independent prognostic factors for PFS and OS included performance status, first-line regimen, and neutrophil-lymphocyte ratio (NLR). Among patients tested, 7.1% had deficient mismatch repair (d-MMR), and 5.8% harbored BRCA mutations. Conclusions This real-world study confirms that clinical outcomes for locally advanced unresectable and metastatic PDAC in Saudi Arabia are consistent with international data, with FOLFIRINOX showing superior outcomes over gemcitabine-based regimens. However, both treatments reflect the persistent poor prognosis of PDAC, underscoring the need for novel therapeutic strategies. Further research is warranted to optimize treatment selection and improve survival outcomes in this population.

The most common surgical procedure for breast cancer is the modified radical mastectomy (MRM), but it is associated with significant postoperative pain. Regional anesthesia can reduce the stress response associated with surgical trauma. Our aim is to explore the efficacy of 1 µg/kg dexmedetomedine added to an ultrasound (US)-modified pectoral (Pecs) block on postoperative pain and stress response in patients undergoing MRM. A randomized, double-blind, prospective study. An academic medical center. Sixty patients with American Society of Anesthesiologists (ASA) physical status I-II (18-60 years old and weighing 50-90 kg) scheduled for MRM were enrolled and randomly assigned into 2 groups (30 in each) to receive a preoperative US Pecs block with 30 mL of 0.25% bupivacaine only (group 1, bupivacaine group [GB]) or 30 mL of 0.25% bupivacaine plus 1 µg/kg dexmedetomidine (group II, dexmedetomidine group [GD]). The patients were followed-up 48 hours postoperatively for vital signs (heart rate [HR], noninvasive blood pressure [NIBP], respiratory rate [RR], and oxygen saturation [Sao2]), visual analog scale (VAS) scores, time to first request of rescue analgesia, total morphine consumption, and side effects. Serum levels of cortisol and prolactin were assessed at baseline and at 1 and 24 hours postoperatively. A significant reduction in the intraoperative HR, systolic blood pressure (SBP), and diastolic blood pressure (DBP) starting at 30 minutes until 120 minutes in the GD group compared to the GB group (P < 0.05) was observed. The VAS scores showed a statistically significant reduction in the GD group compared to the GB group, which started immediately up until 12 hours postoperatively (P < 0.05). There was a delayed time to first request of analgesia in the GD group (25.4 ± 16.4 hrs) compared to the GB group (17 ± 12 hrs) (P = 0.029), and there was a significant decrease of the total amount of morphine consumption in the GD group (9 + 3.6 mg) compared to the GB group (12 + 3.6 mg) (P = 0.001). There was a significant reduction in the mean serum cortisol and prolactin levels at 1 and 24 hours postoperative in the GD patients compared to the GB patients (P < 0.05). This study was limited by its sample size. The addition of 1 µg/kg dexmedetomidine to an US-modified Pecs block has superior analgesia and more attenuation to stress hormone levels without serious side effects, compared to a regular Pecs block in patients who underwent MRM.

Introduction Early enamel demineralization can be reversed through remineralization, which restores lost minerals to strengthen enamel and prevent decay. Aim This study evaluated the remineralization efficiency of three commercial treatments on artificially demineralized primary enamel. Methods Forty exfoliated primary anterior teeth were demineralized and divided into five groups: untreated control, artificial saliva, fluoridated toothpaste, Curasept toothpaste, and BioMin toothpaste. The treatments were applied for 28 days. Remineralization efficacy was assessed using Vickers microhardness testing, surface roughness measurement, and Scanning electron microscope combined with EDX (SEM-EDX). One-way ANOVA and Tukey’s HSD test were used for statistical analysis. Results Microhardness and surface roughness tests confirmed BioMin’s superior remineralization potential. Scanning electron microscopy showed that untreated enamel exhibited extensive demineralization, whereas treated groups displayed varying degrees of remineralization. BioMin demonstrated the highest calcium, phosphate, and fluoride incorporation, followed by Curasept and fluoridated toothpaste. The artificial saliva group showed no significant improvement over the control. Conclusion BioMin, followed by Curasept and fluoridated toothpaste, effectively remineralized demineralized enamel. BioMin’s bioactive glass formulation provided the highest mineral gain, suggesting its potential for non-invasive enamel restoration in pediatric dentistry.

Background Although laparoscopic surgery provides earlier recovery, less morbidity and hospital stay, however, severe pain is still a problem after it. Duloxetine has been recently used in postoperative pain management. We tested perioperative duloxetine to evaluate its effect on patients undergoing laparoscopic colorectal cancer surgery. Methods Sixty patients were enrolled in this study divided into two equal groups; duloxetine group each patient received an oral duloxetine capsule (60 mg) 1st dose at night before surgery, the 2nd dose 1 h preoperative, and the 3rd dose 24 h postoperative. Placebo group received placebo capsules at the same times. The cumulative morphine consumption in 48 h, postoperative VAS score, quality of recovery (QoR-40 score), sedation, and adverse effects were evaluated. Results Duloxetine group had lower VAS scores compared to placebo group, (3 ± 0.69) VS. (4.17 ± 0.83), (2.5 ± 0.6) VS. (4.3 ± 0.9), (2.2 ± 0.7) VS. (3.9 ± 0.6), (1.6 ± 0.7) VS. (3.6 ± 0.8), (1.1 ± 0.8) VS. (3.7 ± 0.7), (0.7 ± 0.7) VS. (3.5 ± 0.8), (0.6 ± 0.7) VS. (3.5 ± 0.8) respectively, P ˂0.01. The cumulative morphine consumption was significantly reduced in the Duloxetine group compared to the placebo group (4.6 ± 2.9 vs. 11.3 ± 1.7 mg), P < 0.01. The total QoR-40 score for duloxetine group was (180.8 ± 4.5) vs. (156 ± 5.9) in placebo group ( P  < 0.01). Patients in Duloxetine group were more sedated in all the 48 h postoperatively in comparison to placebo group. Conclusions Perioperative duloxetine had reduced postoperative pain, decreased opioid consumption, and improved the quality of recovery in patients undergoing laparoscopic colorectal surgery.

Febrile seizures (FSs) are a common occurrence in young children and a serious concern in pediatric practice; nevertheless, the causes and mechanisms of FS are still unknown. We hypothesized a relation of neuropeptides such as neurotrophin-3 (NT-3) and growth-associated protein-43 (GAP-43) as well as zinc and the oxidant/antioxidant system with pediatric FS. The study included 100 infants categorized into 50 infants with FS and 50 febrile infants without seizures as controls. Clinical assessments, biochemical assays of NT-3 and GAP-43 using ELISA assay kits, and colorimetric measurements of TAC and Zn were performed to all participants. Overall, significant rises of the values of NT-3 and insignificant increases of GAP-43 were detected in children with FS. At the same time, zinc values and the total antioxidant capacity in serum samples were found to be decreased significantly. In addition, a negative correlation was estimated between NT-3 and zinc levels. Serum NT-3 in diagnosing febrile seizures at cutoff point > 49.62 ng/L showed 100% sensitivity, 46% specificity, positive predictive value (PPV) = 48.1%, and negative predictive value (NPP) = 100% with AUC = 0.678. Significant altered circulating NT-3 and zinc levels in FS may indicate their possible role in the pathogenesis of FS. This may open a way for further research and warrants enlightening of the pathophysiological details of FS.

Social media sites, particularly Instagram, have recently developed effective instruments for influencing customer behavior, particularly regarding eating experiences and cuisine. This study examines the influence of posting food-related content on Instagram on customers’ intention to visit casual dining restaurants in Saudi Arabia. This study also examined the mediating role of credibility in shaping this intention. A quantitative approach was used through online surveys gathered from 685 Saudi Arabian customers. The major findings of this study revealed that foodstagramming attributes such aesthetic appeal (AA) and post popularity (PP) positively influence customers’ visit intention (VI) in the context of casual dining restaurants in Saudi Arabia. Furthermore, the content credibility (CC) of foodstagramming positively influences customers’ VI. In addition, the CC of foodstagramming partially mediates the relationship between AA, PP, and customers’ VI. Theoretical contributions and practical implications are also provided.

Aims. Assessment of the glycemic outcomes of increasing and splitting mealtime insulin doses for mixed fat and protein meals in pediatric patients with type 1 diabetes mellitus (T1DM) using multiple daily injection regimen and comparing the effects of regular insulin and fast-acting insulin on glycemic outcomes following those meals. Methods. This single-center, randomized, cross-over trial included 43 children and adolescents with T1DM randomly assigned to receive three interventional insulin doses for lunch meals over 3 consecutive days; Intervention A (100% insulin-to-carbohydrate ratio (ICR) dose given as premeal insulin lispro with an additional insulin sensitivity factor-calculated correction dose after 3 hr), Intervention B (130% ICR dose split into 60% premeal insulin lispro and 40% postmeal insulin lispro after 30 min), and Intervention C (130% ICR dose split into 60% premeal insulin lispro and 40% postmeal regular insulin after 30 min). The test meal consisted of two slices of pizza (weight: 150 g, carbohydrates: 40 g, fat: 15 g, protein: 20 g, and calories: 380 kcal). Postprandial blood glucose levels were monitored for 6 hr. Results. There were no significant differences in postprandial blood glucose excursions following the three interventions. However, Intervention C had a significantly lower late (3–6 hr) blood glucose area under the curve (p=0.01). Postprandial hypoglycemia developed in 12 participants (27.9%) following Interventions A and B and in 17 participants (39.5%) following Intervention C (p=0.32). Conclusions. Using regular insulin as a postmeal portion of increased and split insulin doses provided better late postprandial glycemic outcomes following mixed fat and protein meals. However, the amount of additional insulin used needs optimization to reduce the frequency of postprandial hypoglycemia. This trial is registered with NCT04783376.

Major abdominal surgeries are associated with severe pain, which can affect respiratory and cardiac functions if insufficiently treated; this increases postoperative morbidity. We aim at evaluating the efficacy of magnesium sulfate as an adjuvant to local anesthetic in an ultrasound-guided transversus abdominis plane (TAP) block for postoperative analgesia in total abdominal hysterectomy. A prospective, randomized, double-blinded clinical trial. An academic medical center. This study is registered at https://clinicaltrials.gov (no.: NCT02930707). This randomized, double-blinded clinical trial included 60 women undergoing total abdominal hysterectomy that were divided into 2 groups (30 patients per group). Group I received a TAP block with 20 mL per side of 0.25% bupivacaine plus 2 mL magnesium sulphate 10% (200 mg). Group II received a TAP block with 20 mL per side of 0.25% bupivacaine. Visual analog scale (VAS) scores, the time of the first analgesic request, total morphine consumption, and any side effects were assessed and recorded. The mean postoperative VAS score was significantly reduced in group I compared to group II in all of the time-points except after 10 hours. The mean time of the first request for rescue analgesia was significantly prolonged in group I (15.67 hrs.) compared to group II (7.33 hrs.) (P < 0.001), and the mean total morphine consumption, over the first 24 hours postoperatively, was significantly lower in group I (7.63 ± 2.93 mg) than in group II (16.20 ± 3.24 mg) (P < 0.001). No significant difference in side effects was observed. Sample size. The addition of 200 mg of magnesium sulfate to bupivacaine in an ultrasound-guided TAP block significantly reduced postoperative opioid requirements, prolonged the duration of analgesia, and reduced the VAS score in patients who underwent abdominal hysterectomy, without significant side effects. Magnesium sulfate, TAP block, postoperative pain, total abdominal hysterectomy.

Inflammation and oxidative stress play a major role in the development of sepsis and its associated complications, leading to multiple organ failure and death. The lungs, liver, and kidneys are among the early affected organs correlated with mortality in sepsis. Alpha-chymotrypsin (α-ch) is a serine protease that exerts anti-inflammatory, anti-edematous, and anti-oxidant properties. Purpose: This study was undertaken to elucidate if the anti-inflammatory and anti-oxidant effects of α-ch observed in previous studies can alleviate lung, liver, and kidney injuries in a cecal ligation and puncture (CLP)-induced sepsis model, and thus decrease mortality. Materials and Methods: Septic animals were given α-ch 2 h post CLP procedure. Sepsis outcomes were assessed in the lungs, liver, and kidneys. Separate animal groups were investigated for a survival study. Results: CLP resulted in 0% survival, while α-chymotrypsin post-treatment led to 50% survival at the end of the study. Administration of α-chymotrypsin resulted in a significant attenuation of sepsis-induced elevated malonaldehyde (MDA) and total nitrite/nitrate (NOx) levels. In addition, there was a significant increase in reduced glutathione (GSH) content and superoxide dismutase (SOD) activity in the lungs, liver, and kidneys. Administration of α-ch reduced elevated tissue expression of toll-like receptor-4 (TLR4), nuclear factor kappa-B (NF-κB), myeloperoxidase (MPO), and inducible nitric oxide synthase (iNOS). Alpha-chymotrypsin resulted in a significant reduction in serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6). Alpha-chymotrypsin attenuated the rise in serum creatinine, cystatin C, blood urea nitrogen (BUN), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels that was observed in the septic group. In addition, α-ch significantly reduced the lung wet/dry weight ratio, total protein content, and leukocytic counts in bronchoalveolar lavage fluid (BALF). Histopathological examination of the lungs, liver, and kidneys confirmed the protective effects of α-ch on those organs. Conclusion: α-ch has protective potential against sepsis through lowering tissue expression of TLR4, NF-κB, MPO, and iNOS leading to decreased oxidative stress and inflammatory signals induced by sepsis. This effect appeared to alleviate the damage to the lungs, liver, and kidneys and increase survival in rats subjected to sepsis.
