Clinical reappraisal of the composite international diagnostic interview version 3.3 in Qatar's National Mental Health Study.

OBJECTIVES: Lifetime DSM-5 diagnoses generated by the lay-administered Composite International Diagnostic Interview for DSM-5 (CIDI) in the World Mental Health Qatar (WMHQ) study were compared to diagnoses based on blinded clinician-administered reappraisal interviews. METHODS: Telephone follow-up interviews used the non-patient edition of the Structured Clinician Interview for DSM-5 (SCID) oversampling respondents who screened positive for five diagnoses in the CIDI: major depressive episode, mania/hypomania, panic disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Concordance was also examined for a diagnoses of post-traumatic stress disorder based on a short-form versus full version of the PTSD Checklist for DSM-5 (PCL-5). RESULTS: Initial CIDI prevalence estimates differed significantly from the SCID for most diagnoses ( χ 1 2 ${\chi }_{1}^{2}$  = 6.6-31.4, p = 0.010 < 0.001), but recalibration reduced most of these differences and led to consistent increases in individual-level concordance (AU-ROC) from 0.53-0.76 to 0.67-0.81. Recalibration of the short-form PCL-5 removed an initially significant difference in PTSD prevalence with the full PCL-5 (from χ 1 2 ${\chi }_{1}^{2}$  = 610.5, p < 0.001 to χ 1 2 ${\chi }_{1}^{2}$  = 2.5, p = 0.110) while also increasing AU-ROC from 0.76 to 0.81. CONCLUSIONS: Recalibration resulted in valid diagnoses of common mental disorders in the Qatar National Mental Health Survey, but with inflated prevalence estimates for some disorders that need to be considered when interpreting results.

Plexin B2 tissue expression and related gene polymorphisms in psoriasis and their relation to NB-UVB and Acitretin therapy.

Psoriasis is a chronic, immune-mediated, hyperproliferative skin disease. Etiopathogenesis of psoriasis is not well understood. Plexin B2 was found to have effects on CD100-mediated T-cell morphology and expressed in the immune system. It may play a role in the pathogenesis of psoriasis. To assess the tissue level of plexin-B2 and plexin B2 related gene polymorphism which is signal regulatory protein gamma (SIRPγ-rs71212732) in psoriatic patients before and after NB-UVB, acitretin therapy alone or in combination and to detect correlation between level of tissue plexin B2 and disease severity and improvement. This single blinded randomized controlled trial was carried on 50 psoriatic patients and 50 healthy controls. Psoriasis Area and Severity Index score (PASI) was used to evaluate the disease severity. Tissue plexin-b2 level was measured using ELISA and SIRPγ-rs71212732 (T\C) was assessed using TaqMan™ assays and real-time PCR. A significant lower tissue plexin-B2 level was observed in control group (2.9 ± 0.6 pg/g) than cases (25.8 ± 2.8, pg/g) (p < 0.001). Also, a significantly higher tissue plexin-B2 level was observed in sever psoriasis (32.7 ± 3.8 pg/ml) in than moderate psoriasis (13.6 ± 2.1 pg/ml, p = 0.001). Tissue plexin B2 was positively correlated with diseases severity. Significantly higher (TC& TT) genotypes and mutant (C) allele among patients compared to the controls, p < 0.001 for all. Tissue plexin-b2 level was high in psoriasis vulgaris with positive correlation with disease severity and decreased after treatment. This may indicate a role of plexin-b2 in psoriasis vulgaris pathogenesis.

The deleterious effects of sofosbuvir and ribavirin (antiviral drugs against hepatitis C virus) on different body systems in male albino rats regarding reproductive, hematological, biochemical, hepatic, and renal profiles and histopathological changes.

Sofosbuvir is one of the crucial drugs used in the treatment of chronic hepatitis C virus (HCV) in adults and children with compensated liver disease, including cirrhosis. It may be used alone or with other drugs. Ribavirin is an antiviral medication used to treat HCV infection. It is not effective when used alone and must be used in combination with other medications, such as sofosbuvir. This study pertains to a comprehensive assessment of the deleterious effects of sofosbuvir (an antiviral drug against chronic HCV) or sofosbuvir combined with ribavirin (an antiviral drug against RNA and DNA viruses) on several biological activities of the body, including hematological, hormonal, biochemical, histological, and immunohistochemical examinations during a long-standing period on male healthy rats. In addition, fertility assessments were performed, including sperm collections and semen parameter investigations. This study was conducted on 21 male rats divided into three equal groups. Group I (control group) received distilled water; group II (sofosbuvir group) received sofosbuvir (4 mg/kg); and group III (sofosbuvir + ribavirin) received sofosbuvir (4 mg/kg) plus ribavirin (30 ml/kg). All groups received the specific drug for six months. Blood and tissue samples were collected for hematological, hormonal, biochemical, histological, and immunohistochemical examinations. In addition, sperm collection and assessments of semen parameters were performed. Results revealed that sofosbuvir causes a highly significant decrease in the mean of most hematological, immunological, hormonal, and biochemical parameters, except for a few numbers of parameters such as neutrophils, monocytes, basophils, cortisol, GOT, and lipase, which exhibit a significant increase. The same occurred in the sofosbuvir + ribavirin group, but at much higher levels, as most hematological, immunological, hormonal, and biochemical parameters exhibit a highly significant decrease except for monocytes, triglyceride, and lipase, which exhibit a significant increase. When compared to the sofosbuvir group alone, the sofosbuvir + ribavirin group demonstrated a highly significant decline in the mean of most hematological, immunological, hormonal, and biochemical parameters except lymphocytes and triglycerides, which exhibit a substantial increase. For the reproductive parameters, both groups exhibit a significant decrease in the total sperm motility percentage. Finally, it can be concluded that sofosbuvir causes acute pancreatitis and combined immunodeficiency. Ribavirin is associated with hormonal deficiency, which indicates the occurrence of hypopituitarism. Moreover, sofosbuvir and ribavirin synergistically affect myelosuppression and cause iron-deficiency anemia. However, sofosbuvir, or its combination with ribavirin, is associated with a reduced risk of hepatocellular carcinoma. Besides, adding ribavirin to be combined with sofosbuvir improved the immunodeficiency caused by sofosbuvir; this confirms that using ribavirin with sofosbuvir reduces the side effects of both alone.

Pharmacogenetic study of phosphatase and tensin homolog polymorphism (rs701848) in childhood epilepsy: relation to circulating Wnt signaling.

OBJECTIVE: The present study aimed at evaluating the potential contribution of Phosphatase and Tensin Homolog (PTEN) and its gene polymorphism (PTEN rs701848 T/C) in relation to Wingless/integrase-1 (Wnt) signaling in childhood epilepsy and the impact of antiepileptic medications on their serum levels. METHODS: This study included 100 children with epilepsy (50 pharmacoresistant and 50 pharmacoresponsive) and 50 matched controls. All subjects had their genotypes for the PTEN rs701848T/C polymorphism assessed using TaqManTM assays and real-time PCR. By using the sandwich ELISA technique, the blood concentrations of PTEN and Wnt3a were measured. RESULTS: Serum Wnt3a levels in epileptic patients were significantly higher than in the control group, p < 0.001. Children with epilepsy who received oxcarbazepine had considerably lower serum Wnt3a levels than those who didn't, p < 0.001.With an AUC of 0.71, the cutoff value for diagnosing epilepsy as serum Wnt3a > 6.2 ng/mL has a sensitivity of 55% and a specificity of 80%. When compared to controls, epileptic children had considerably more (TT) genotype and less (TC and CC) genotypes, p < 0.05 for all. Epileptic children had significantly higher (T) allele frequency than controls, p = 0.006 with OR (95%CI) = 1.962(1.206-3.192). Pharmacoresistant epileptic children had significantly higher (TT) genotype compared to pharmacoresponsive type (p = 0.020). CONCLUSION: We originally found a strong association between PTEN rs701848 T/C and childhood epilepsy, in particular pharmacoresistant type. Serum Wnt3a levels increased in epilepsy, but were not significantly different between different alleles of PTEN. In pharmaco-responsive children Wnt3a levels differed significantly between the different PTEN genotypes. Antiepileptics may affect Wnt3a levels.

Social Media Effect on Personal Self-Esteem Among the Population in Saudi Arabia.

Background Self-esteem is a self-valuation; it is how people perceive their own worth and how valuable they believe they are to others. In this study, our primary objective was to explore the association between social media use and self-esteem among individuals who actively engage with social media platforms in Saudi Arabia. Method This study involved individuals aged 15 and above who are active social media users residing in Saudi Arabia. The data were collected through an anonymous online cross-sectional survey. Participants were recruited using snowball and convenience sampling method. A questionnaire was administered through Google Forms to collect data from participants. The questionnaire was structured into three sections, which included gathering social and demographic information, assessing personal usage patterns, and evaluating individual self-esteem levels using an Arabic valid version of the Rosenberg Self-Esteem Scale.  Results The survey included a total of 2,551 participants. Among them, 51.3% (n = 1,309) were female, 29% (n = 741) fell within the 21-25 age group, 95.7% (n = 2,441) were of Saudi nationality, and 51.6% (n = 1,316) were single. The social media platform most frequently used by participants was TikTok 98.5% (n = 2,512), followed by Facebook 95.7% (n = 2,441), Telegram 89.8% (n = 2,291), YouTube 72.2% (n = 1,942), WhatsApp 66.0% (n = 1,683), and finally, Snapchat 30.7% (n = 1,769). In total, 14.3% (n= 366) have low self-esteem, participants scored around 16.10 ± 1.80, ranging from 5 to 25. The following variables were significantly associated with self-esteem: female sex (83.88% vs 87.52%, X2 = 6.87, p = 0.009), nationality (X2 = 13.507, p < 0.001), marital status (X2 = 12.313, p = 0.006), region (X2 = 18.36, p = 0.001), using Tik Tok (X2 = 4.11, p = 0.043), the frequency of posting comments (X2 = 12.01, p = 0.017), comparing oneself to others (X2 = 27.94, p < 0.001), using social media because of weak personal communication (X2 = 6.56, p = 0.010), using social media to follow news (X2 = 6.89, p = 0.009), and the perceived effect of social media (X2 = 16.28, p < 0.001). Conclusions Our findings revealed that a minority of participants exhibited low self-esteem, and individuals from the Northern region were more likely to report such issues. Sociodemographic factors, including gender, nationality, and marital status, demonstrated associations with self-esteem. Additionally, the frequency of comments, TikTok usage, and peer comparison significantly influenced self-esteem levels.

Validity of Serum Zinc/Copper Ratio as a Potential Novel Biomarker in Childhood Epilepsy.

BACKGROUND: Alterations in zinc and copper homeostasis may contribute to seizure susceptibility, development, termination, and response to antiepileptic medications. The current study examined the profile of zinc, copper, and their ratio in childhood epilepsy and its pharmacological variants (pharmacoresistant and pharmacoresponsive). METHODS: The study included 100 epileptic children (50 pharmacoresistant and 50 pharmacoresponsive) and 50 healthy, age- and gender-matched controls. History, clinical examination, and assays of serum zinc and copper were performed. Zinc/copper ratio was calculated. RESULTS: Serum zinc and the zinc/copper ratio were significantly lower in epileptic children than in controls (p < 0.001). Significantly lower zinc and zinc/copper ratio and higher copper levels were found in children treated with levetiracetam/sodium valproate/oxcarbazepine than those treated with levetiracetam alone or combined with sodium valproate (p < 0.05 for all). Epileptic children, particularly pharmacoresistant, exhibited significant negative correlations between the serum levels of zinc and copper (r = -0.279, p = 0.005, and r = -0.363 and p = 0.010, respectively). At cutoff value of zinc/copper ratio < 1.118 in diagnosing children with epilepsy, it gives a sensitivity of 64% and a specificity of 85% with the AUC = 0.8092. At cutoff value of zinc/copper ratio ≤ 0.7826 in distinguishing pharmacoresistant epilepsy, it produced 52% sensitivity, 64% specificity with AUC = 0.576 Conclusions: Low zinc and high copper levels were associated with childhood epilepsy especially those with pharmacoresistant type and treated with Oxcarbazepine. Zinc/copper ratio might be a potential biomarker in diagnosing childhood epilepsy and to some extent in predicting pharmacoresistant type.

Profile of plasma free amino acids, carnitine and acylcarnitines, and JAK2v617f mutation as potential metabolic markers in children with type 1 diabetic nephropathy.

Fifty diabetic nephropathy (DN) children with type 1 diabetes mellitus (T1DM) and 50 healthy matched controls were included. Chromatographic assays of 14 amino acids, free carnitine and 27 carnitine esters using high-performance liquid chromatography/electrospray ionization-mass spectroscopy, and genetic testing for JAK2v617f mutation using real-time PCR were performed. Patients had significantly lower levels of tyrosine, branched-chain amino acids (BCAAs), and BCAA/AAA (aromatic chain amino acids) ratios, glycine, arginine, ornithine, free carnitine and some carnitine esters (C5, 6, 12 and 16) and higher phenylalanine, phenylalanine/tyrosine ratio and C18 compared with the controls and in the macro-albuminuria vs. the microalbuminuria group (p < 0.05 for all) except for free carnitine. Plasma carnitine was negatively correlated with eGFR (r = -0.488, p = 0.000). There were significant positive correlations between tyrosine with UACR ratio (r = 0.296, p = 0.037). The plasma BCAA/AAA ratio showed significant negative correlations with UACR (r = -0.484, p = 0.000). There was a significantly higher frequency of the JAK2V617F gene mutation in diabetic nephropathy patients compared with the control group and in macro-albuminuria than the microalbuminuria group (p = 0.000) for both. When monitoring children with T1DM, plasma free amino acids and acylcarnitine profiles should be considered, especially if they have tested positive for JAK2V617F for the early diagnosis of DN.

Body Mass Index as a Major Prognostic Contributing Factor in COVID-19: A Multicentral Egyptian Study.

Background: Extreme body mass index (BMI) is an influential pathophysiological risk factor for serious illnesses following lower respiratory tract infection. The purpose of the current study was to examine how the BMI of Coronavirus disease-19 (COVID-19) patients affects their prognosis. Methods: Two hundred patients with COVID-19 admitted to Al-Azhar, Qena, Aswan, and Sohag University hospitals in Egypt were included and categorized into four groups according to their BMI. The diagnosis was made according to a real-time reverse transcription-polymerase chain reaction (rRT-PCR) positive result for the SARS-CoV-2 nucleic acid in swabs from upper respiratory tract. A detailed history, clinical examination, and outcomes (disease severity and complications, hospital stay, ICU admission, mortality) were recorded for all patients. SPSS version 24 software was used for data analysis. Results: Average age of participants (19-90 years old), 92 (46%) males and 108 females (54%). ICU admission was significantly higher among underweight patients (75%) and obese patients (78.6%). The majority of underweight (62.5%) and obese (57.1%) patients had critical disease. Invasive mechanical ventilation (MV) is frequently used in underweight (50%) and obese patients (42.9%) patients. Adult respiratory distress syndrome (ARDS), cardiac, neurological, and hematological complications, and incidence of myalgia and bed sores were most frequent among obese and overweight patients. Acute kidney injury was significantly higher among underweight patients (37.5%) and obese patients (28.6%) than among other classes (p=0.004). Frequency of endocrine complications was significantly higher in underweight patients than that in other classes (p=0.01). The majority of underweight (75%) and obese patients (50%) deteriorated and died, whereas the majority of normal-weight patients (90.3%) and overweight patients (75.8%) improved and were discharged (p< 0.001). Conclusion: Body mass index is a major contributing factor to the outcome of patients with COVID-19, and patients with extreme of body mass index were associated with the worst prognosis.

Impact of Myocardial Ischemia and Revascularization by Percutaneous Coronary Intervention on Circulating Level of Soluble ST2.

Background: The prognostic role of the soluble circulating suppression of tumorigenicity 2 marker (sST2) in different cardiovascular diseases (CVD) is still under investigation. This research aimed to assess the serum levels of sST2 in the blood of individuals with ischemic heart disease and its relation to disease severity, also to examine any changes in sST2 levels following a successful percutaneous coronary intervention (PCI) in those patients. Methods: A total of 33 ischemic patients and 30 non-ischemic controls were included. The plasma level of sST2 was measured using commercially available ELISA assay kit, at baseline and 24-48 h after the intervention in the ischemic group. Results: On admission, there was a significant difference between the group of acute/chronic coronary syndrome cases and controls regarding the sST2 plasma level (p < 0.001). There was an insignificant difference between the three ischemic subgroups at the baseline sST2 level (p = 0.38). The plasma sST2 level decreased significantly after PCI (from 20.70 ± 1.71 to 16.51 ± 2.43, p = 0.006). There was a modestly just significant positive correlation between the acute change in post-PCI sST2 level and the severity of ischemia as measured by the Modified Gensini Score (MGS) (r = 0.45, p = 0.05). In spite of the highly significant improvement in the coronary TIMI flow of ischemic group after PCI, there was insignificant negative correlation between the post- PCI delta change in the sST2 level and the post-PCI TIMI coronary flow grade. Conclusion: A significantly high plasma level of sST2 in patients with myocardial ischemia and controlled cardiovascular risk factors showed an immediate reduction after successful revascularization. The high baseline level of the sST2 marker and the acute post-PCI reduction was mainly related to the severity of ischemia rather than left ventricular function.

Possible Role of Helicobacter pylori in Ear Nose and Throat Diseases.

Background: Helicobacter pylori is assumed to cause many gastric and extragastric diseases. We aimed to assess the possible association role of H. pylori in Otitis media with effusion (OME), nasal polyps and adenotonsillitis. Patients and Methods: A total of 186 patients with various ear, nose and throat diseases were included. The study comprised 78 children with chronic adenotonsillitis, 43 children with nasal polyps and 65 children with OME. OME patients were assigned to two subgroups: those who have and those who did not have adenoid hyperplasia. Among the patients with bilateral nasal polyps, 20 individuals had recurrent nasal polyps and 23 had de novo nasal polyps. Patients who have chronic adenotonsillitis were divided into three groups: those with chronic tonsillitis and those who underwent tonsillitis, those with chronic adenoiditis and adenoidectomy was performed, and those with chronic adenotonsillitis and underwent adenotonsillectomy. In addition to examination of H. pylori antigen in stool samples of all included patients, real-time polymerase chain reaction (RT-PCR) for detection of H. pylori in the effusion fluid was performed, additionally, Giemsa stain was used for detection of H. pylori organism within the tissue samples when available. Results: Frequency of H. pylori in effusion fluid was 28.6% in patients with OME and adenoid hyperplasia, while in those with OME it was only 17.4% with a p value of 0.2. Nasal polyp biopsies were positive in 13% patients of denovo, and 30% patients with recurrent nasal polyps, p=0.2. De novo nasal polyps were more prevalent in the positive stools than recurrent ones, p=0.7. All adenoid samples were negative for H. pylori, only two samples of tonsillar tissue (8.3%) were positive for H. pylori, and stool analysis was positive in 23 patients with chronic adenotonsillitis. Conclusion: Lack of association between Helicobacter pylori and occurrence of OME, nasal polyposis or recurrent adenotonsillitis.

Metabolic Analysis of Methylenetetrahydrofolate Reductase Single Nucleotide Polymorphisms (MTHFR 677C

Neural tube defects (NTDs) are among the most prevalent and debilitating birth defects with their causes are still unknown, despite mounting evidence that genetic and/or environmental factors may play a role. We aimed to analyze two single nucleotide polymorphisms of methylenetetrahydrofolate reductase (MTHFR) gene, serum folate and vitamin B12 status among a cohort of Egyptian children with NTDs and their mothers. A case-control study has been conducted on 50 Egyptian children with various types of NTDs and their mothers. They were comparable with 50 unrelated healthy, age and sex matched children and their mothers (50) selected as controls. Pediatric and neurosurgical assessments were performed to the included cases. Serum folate and vitamin B12 were measured using ELISA kits. MTHFR 677C

Knowledge and Practice of the Preventive and Care Methods for Diabetic Foot Among the Caregivers of Diabetic Patients in Saudi Arabia.

Background Diabetic foot syndrome is a complex and multifactorial disease process involving neuropathy, peripheral arterial disease, osteomyelitis, diabetic foot ulcer (DFU), and amputation. DFUs are a common and burdensome manifestation of the syndrome, responsible for diabetes-related morbidity and mortality. Successful management of DFU requires collaboration between patients and caregivers. This study assesses the knowledge, experience, and practices of the caregivers of diabetic foot patients in Saudi Arabia, highlighting the need for targeted interventions to improve knowledge and practices in certain subgroups of caregivers. Method The primary objective of this study was to evaluate the proficiency and practicality of caregivers who provide care to patients with diabetic foot in the Kingdom of Saudi Arabia. To accomplish this, a cross-sectional study was conducted among caregivers of diabetic foot patients who were aged 18 years or older and living in Saudi Arabia. The participants were randomly chosen to ensure that the sample was representative. The data collection process involved the distribution of a structured online questionnaire via various social media platforms. Prior to the distribution of the questionnaire, the participants were informed about the study's objectives, and their informed consent was obtained. Additionally, adequate measures were taken to ensure the confidentiality of the participants and their caregiving status. Results Among the initial pool of 2990 participants, 1023 individuals were excluded from the study due to their status as non-caregivers of diabetic patients or being under the age of 18 years. Consequently, the final sample size consisted of 1921 caregivers. The majority of the participants were female (61.6%), married (58.6%), and had a bachelor's degree (52.4%). The findings revealed that 34.6% of caregivers were attending to patients with diabetic foot, of which 8.5% reported poor foot status and 9.1% reported amputation. Caregivers reported examining the patient's feet in 75.2% of cases, and the feet were cleaned and moisturized by either the patient or caregiver. Nails were trimmed by 77.8% of caregivers, and 49.8% of them did not permit patients to walk barefoot. Moreover, knowledge of diabetic foot care was positively correlated with being female, having a post-graduate degree, having personal experience with diabetes, caring for a patient with diabetic foot, and having prior experience in treating diabetic foot. Conversely, lower knowledge levels were associated with divorced or unemployed caregivers and those residing in the northern region. Conclusion The present study highlights that caregivers of diabetic foot patients in Saudi Arabia possess a satisfactory level of knowledge and follow appropriate practices regarding foot care. Nonetheless, it is imperative to identify specific subgroups of caregivers who may require additional education and training to improve their knowledge and practices concerning diabetic foot care. The results of this study could potentially inform the design of tailored interventions aimed at reducing the significant burden of morbidity and mortality attributed to diabetic foot syndrome in the Saudi Arabian context.

Genetic profile of MIF single nucleotide polymorphism (rs755622 G>C) in hepatocellular carcinoma among Egyptian patients.

Aim of the study: To evaluate the role of MIF gene polymorphism rs755622 G>C in occurrence and progression of hepatocellular carcinoma (HCC) among a cohort of Egyptian patients. Material and methods: This case-control study was conducted on 50 patients with HCC after chronic viral hepatitis and 50 healthy volunteers, recruited between July 2021 and January 2022. All patients with HCC were evaluated for severity of liver disease using a Child-Pugh score, and TNM and BCLC scoring systems. MIF 173 G>C (rs755622) single nucleotide polymorphism was performed for all participants by polymerase chain reaction using restriction fragment length polymorphism technique (RFLP-PCR). Results: Overall results showed significantly higher frequencies of GG (wild homozygous genotype) and mutant heterozygous genotype GC and G allele (OR = 6.303, 95% CI: 3.374-11.775) among patients with HCC compared to the control group (p = 0.001) for all. Also, significantly higher frequency of genotype GG was detected among patients with advanced Child scores (B and C) (p = 0.039) and TNM stages (III and IV) (p = 0.013). There was significantly higher frequency of the G allele among patients with multiple hepatic focal lesions compared to those with a single focal lesion (p = 0.01). Conclusions: An obvious role of MIF (rs755622) gene polymorphism could have an important role in susceptibility and progression of HCC among patients with chronic viral hepatitis induced liver cirrhosis.

Serum Levels of Growth-Associated Protein-43 and Neurotrophin-3 in Childhood Epilepsy and Their Relation to Zinc Levels.

BACKGROUND: Epilepsy is one of the most common neurological disorders, and it places a significant economic strain on the healthcare system around the world. Although the exact mechanism of epilepsy has yet to be illustrated, various pathogenic cascades involving neurotransmitters and trace elements have been reported. We aimed to investigate the serum levels of growth-associated protein-43 (GAP-43) and neurotrophin-3 (NT-3) among cohort of Egyptian children with epilepsy and correlate these biomarkers with their zinc levels. METHODS: This case-control study included 50 pediatric patients with epilepsy who were comparable with 50 controls. Neurological assessment and electroencephalogram (EEG) were done to all included children. Biochemical measurements of serum GAP-43 and NT-3 using enzyme linked immunosorbent assays (ELISA), and total antioxidant capacity (TAC) and zinc using colorimetric assays, were performed to all participants. RESULTS: There was significantly frequent positive parental consanguinity among cases with significantly frequent generalized onset seizures (94%) than simple partial seizure (6%). There were significantly lower serum GAP-43 and zinc levels with significantly higher TAC among cases vs. the controls, p˂0.05 for all. There was no significant difference in the serum levels of NT-3 among epileptic children vs. the controls, p = 0.269. Serum Zn was positively correlated with GAP-43 level among epileptic children (r = 0.381, p = 0.006). Serum GAP-43 in diagnosing childhood epilepsy at cut-off point ≤ 0.6 ng/mL showed 78% sensitivity, 62% specificity, positive predictive value (PPV) = 50.6%, negative predictive value (NPP) = 84.9% with AUC = 0.574. CONCLUSION: GAP-43 can be considered a sensitive good negative biomarker in childhood epilepsy which correlated positively with the zinc status.

Antitoxic Effects of Curcumin against Obesity-Induced Multi-Organs' Biochemical and Histopathological Abnormalities in an Animal Model.

Background: Obesity is a significant public health problem that is characterized by an increase in oxidative stress and enhanced inflammatory responses associated with immune cell invasion of adipose tissues. This study assessed several biochemical abnormalities, apoptosis, oxidative stress status, and associated histological changes in the liver, duodenum, and heart brought on by high-fat diet-induced obesity in rats. It also assessed the mechanistic benefits of curcumin in reversing these inflammatory, metabolic, and histological impairments. Methods: Rats were assigned into three groups each including ten rats: the control group (CD), the high-fat diet group (HFD), and the high-fat diet + curcumin (HFDC) group. Serum glucose, insulin, and triglycerides (TAGs) were observed. In addition, apoptosis (indicated by hepatic DNA fragmentation) and oxidative stress status (indicated by hepatic MPO, GSH, and SOD) were assessed. Histopathological examinations included the GIT (liver and duodenum) and heart in addition to quantitative real-time polymerase chain reaction (qRT-PCR) assays of the adipose tissue genetic expressions for inflammatory signaling pathways (TLR4, IL-6, and TNF-α). Results: The overall findings showed that the HFD group exhibited significantly higher levels of glucose, TAGs, and insulin than the control group (P < 0.01). The histological abnormalities of the studied organs in the HFD group were paralleled by these biochemical abnormalities, which were strongly associated with increased apoptosis, increased oxidative stress, and increased expression of the inflammatory signaling markers. There were significant improvements in the HFDC group in terms of biochemical, inflammatory, and histological investigations. Conclusions: This study's findings concluded that obesity is significantly associated with biochemical and microscopic alterations in many organs. Curcumin exerted potent antitoxic, antioxidant, tissue-protective, and antiobesity effects. Curcumin is recommended to be added to various dietary regimens to prevent or delay the organs' dysfunction among obese people.

Possible Role of Ivermectin Mucoadhesive Nanosuspension Nasal Spray in Recovery of Post-COVID-19 Anosmia.

Purpose: Anosmia or hyposmia, with or without taste changes, are common symptoms that occur in SARS-CoV-2 infection and frequently persist as post-COVID-19 manifestations. This is the first trial to assess the potential value of using local ivermectin in the form of a mucoadhesive nanosuspension nasal spray to treat post-COVID-19 anosmia. Methods: It is a controlled, randomized trial. Participants were recruited from South Valley University Hospitals in Qena, Upper Egypt, from the ENT and Chest Diseases Departments and outpatient clinics. Patients with persistent post COVID-19 anosmia were randomly divided into two groups, the first group "ivermectin group" included 49 patients treated by ivermectin nanosuspension mucoadhesive nasal spray (two puffs per day). The second group included 47 patients "placebo group" who received saline nasal spray. Follow- up of anosmia [using Visual analogue scale (VAS)] in all patients for three months or appearance of any drug related side effects was done. Results: The mean duration of pre-treatment post COVID-19 anosmia was 19.5± 5.8 days in the ivermectin group and 19.1± 5.9 days in the placebo group,p˃0.05. Regarding the median duration of anosmia recovery, the ivermectin group recovered from post COVID-19 anosmia in 13 days compared to 50 days in the placebo group, p˂ 0.001. Following the first week of ivermectin nanosuspension mucoadhesive nasal spray therapy, the ivermectin group had a significantly higher percentage of anosmia recovery (59.2%) than the placebo group (27.7%), p˂ 0.01, with no significant differences in recovery rates between the two groups at 1, 2, and 3 months of follow up, p˃0.05. Conclusion: In the small number of patients treated, local Ivermectin exhibited no side effects. In persistent post-COVID-19 anosmia, it could be used for one week at the most as the treatment was extended to one, two and three months, with no difference in recovery compared to the placebo treatment. Trial Registration No: NCT04951362.

Circulating Ubiquitin Carboxyl Terminal Hydrolase L1 and Neuroglobin Levels in Traumatic Spinal Cord Injuries: Relation to Severity and Outcomes.

Introduction: Traumatic spinal cord injury (TSCI) is a life-threatening neurological disorder and there is a lack of biomarker research, particularly human studies that could help to categorize the severity and predict the outcome. We aimed to assess the role of serum Ubiquitin C-terminal hydrolase L1 (UCH-L1) and Neuroglobin (NGB) in predicting severity and outcome of TSCI. Methods: This prospective study included 63 participants categorized into 33 patients with various types of TSCI and 30 unrelated healthy volunteers. Neurosurgical [American spinal injury association (ASIA) impairment score (AIS)] and radiological [using spine computed tomography (CT) and magnetic resonance imaging (MRI)] assessments were performed on the included patients to determine the severity and the level of injury with neurological follow-up of patients within 6 months post-injury. Serum UCH-L1 and NGB were measured for all participants using commercially available ELISA assay kits. Results: Of the included patients, 20 (60.60%) had partial SCI and the remaining 13 patients (39.39%) had complete SCI. On follow-up, 19 patients (57.57%) showed improved AIS, while 14 cases (42.42%) did not show any improvement in their AIS scores. There was significantly higher median serum UCHL1 value among cases compared to controls (1723 pg/mL and 657 pg/mL, respectively), p ˂ 0.05. There was an insignificant rise of serum NGB levels among cases in comparison with the controls (15.2pg/mL and 7.52pg/mL, respectively, p ˃ 0.05). Significantly lower initial median serum UCHL1 levels (pg/mL) were observed in patients with improved AIS during the neurological follow-up compared with those who did not show any improvement in their AIS score (1723, and 4700 respectively, p ˂ 0.05), with lack of significant difference in the initial median serum NGB levels, p ˃ 0.05. Conclusion: Initial serum UCHL1 assay could be a helpful marker in reflecting the degree of TSCI and predicting its outcome, though NGB needs further assessment.

Expression Patterns of Macrophage Migration Inhibitory Factor and Its Gene Variants (MIF-173 G˃C) in Verruca Vulgaris.

Introduction: Verruca vulgaris is a benign hyperkeratotic proliferation of the epidermis. Few studies look at the differences in serum and tissue macrophage migration inhibitory factor (MIF) levels in verruca vulgaris, as well as its gene polymorphisms that have yet to be explored. The current study provided in-depth evaluation of MIF in serum and tissues of patients with verruca vulgaris, and establishes for the first time the possible association of MIF gene polymorphisms with common warts. Methods: This case-control study included 50 patients who were diagnosed clinically as common warts in comparison with 50 age and sex-matched controls. Clinical examination was done on all included cases. Serum MIF was measured using enzyme-linked immunosorbent assay (ELISA), while its tissue expression was analyzed using Western blotting and immunohistochemical techniques for the included participants. Analysis of MIF-173 G˃C single nucleotide polymorphism was performed by polymerase chain reaction (PCR) using restriction fragment length polymorphism (RFLP) technique. Results: The overall results revealed significantly lower MIF tissue expression in lesional and perilesional skin biopsies from cases compared to the controls using Western blot and immunohistochemical analysis. Yet, the difference in the serum MIF levels between cases and controls was not significant (p ˃ 0.05). GC genotype of the studied MIF rs755622 G>C SNP could be considered as a protective genetic factor against the occurrence of verruca vulgaris among Egyptians with OR (95% CI) equal 0.444 (0.199-0.989). Conclusion: MIF and its genetic variants are thought to play a pathogenic role in verruca vulgaris development and recurrence.

Validity of B-Type Natriuretic Peptide, Growth Differentiation Factor 15, and High-Sensitivity Troponin I Levels in Ischemic Heart Failure.

BACKGROUND: Heart failure (HF) is a major medical, and epidemiological problems with ischemic heart disease (IHD) is the most common cause of HF. We aimed to assess the plasma B-type natriuretic peptide (BNP) levels, serum growth differentiation factor 15 (GDF15), and high-sensitivity troponin I (hsTnI) in HF patients with and without IHD. METHODS: The study included 120 HF patients, categorized into 51 patients with IHD and 69 patients without apparent IHD. Clinical and echocardiographic assessments of the included patients were performed. ELISA assays of plasma BNP and serum GDF15 were done, while serum hsTnI was measured using chemiluminescent immunoassay. RESULTS: There were significantly higher median values of serum levels for GDF15 (pg/mL) and hsTnI (pg/mL) among IHD group (1,630.5 and 141.8, respectively) compared to non-IHD group (895 and 14.3, respectively, p ˂ 0.05 for both), with non-significant differences regarding to the BNP plasma levels (p ˃ 0.05). In the IHD group, significant positive correlations were observed between GDF15 with both BNP (r = 0.655, p = < 0.001) and hsTnI (r = 0.496, p = < 0.001). Serum GDF15 at a cutoff of ≤ 717 pg/mL has the highest specificity [85.51% vs. 50.72% for BNP (at cutoff > 264 pg/mL) and 59.42% for hsTnI]. Additionally, hsTnI at a cutoff of > 45.2 pg/mL has the highest sensitivity (70.59% vs. 68.63% for BNP and 33.33% for GDF15) in discriminating heart failure with IHD from heart failure without IHD. CONCLUSIONS: A multimarker approach, particularly GDF15 and hsTnI, is helpful in identifying HF patients with underlying IHD, thus enabling their proper management.

Biochemical Assessments of Neurotrophin-3 and Zinc Involvement in the Pathophysiology of Pediatric Febrile Seizures : Biochemical Markers in Febrile Seizures.

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.
