The Effect and Implication of Social Media Platforms on Cosmetic Facial Plastic Surgery Among Females in Saudi Arabia.

Introduction Facial plastic surgery addresses various facial imperfections, offering a range of procedures like rhinoplasty and facelifts. Social media promotes unrealistic beauty standards, leading to increased demand for such surgeries. Studies highlight its influence, emphasizing the need for research in this area. Our study aimed to evaluate the effect of social media advertisements and selfies on facial cosmetic surgery decisions and plans among females in Saudi Arabia. Methodology This is a cross-sectional study conducted in the Kingdom of Saudi Arabia that targeted females aged 18-80 years old. An electronic questionnaire in Arabic was used for data collection. Data was analyzed in IBM SPSS Statistics for Windows, Version 29 (Released 2023; IBM Corp., Armonk, New York, United States). Results Our study assessed 568 Saudi females regarding social media's impact on facial cosmetic surgery. Most of them were aged 21-30 years (39.4%) and Saudi nationals (94.2%). The majority, 87.9% (n=499), had not undergone cosmetic surgeries, and 12.1% (n=69) had; 68.1% (n=387) did not plan future surgeries. Notably, 42.6% (n=242) cited surgeon self-advertising and 38.0% (n=216) better selfies as an influencing factor in their cosmetic surgery decision. Logistic regression revealed several significant predictors of cosmetic surgery decisions including surgeon's advertisement (Exp(B) = 2.812, p < 0.001), cosmetic show viewing (Exp(B) = 2.327, p = 0.004), and social media photos (Exp(B) = 2.762, p = 0.001). Education (Exp(B) = 1.533, p = 0.035) and previous surgery (Exp(B) = 4.523, p < 0.001) correlated positively with considering surgery. Conclusion Our study highlights social media's influence on facial cosmetic surgery decisions among Saudi females. Surgeon advertisements, social media exposure, education, and previous surgery history emerged as significant predictors, warranting further research and targeted interventions.

IgG4-Related Disease of the Central Nervous System: A Case Series.

IgG4-related disease (IgG4-RD) is a rare and often misdiagnosed disorder with limited literature that highlights the different neurological presentations of this treatable disease. The diagnosis of IgG4-RD could be challenging, while imaging is fundamental for the diagnosis, biopsy is considered the gold standard. Most cases respond well to steroids and immunosuppressive therapy. This is a case series study that illustrates the varied neurological presentations of IgG4-RD through three different patients that were followed at the Montreal Neurological Institute. This paper takes you through the diagnostic strategy that we followed to accurately diagnose and treat those patients.

Effects of Independent Component Analysis on Magnetoencephalography Source Localization in Pre-surgical Frontal Lobe Epilepsy Patients.

Objective: Magnetoencephalography source imaging (MSI) of interictal epileptiform discharges (IED) is a useful presurgical tool in the evaluation of drug-resistant frontal lobe epilepsy (FLE) patients. Yet, failures in MSI can arise related to artifacts and to interference of background activity. Independent component analysis (ICA) is a popular denoising procedure but its clinical application remains challenging, as the selection of multiple independent components (IC) is controversial, operator dependent, and time consuming. We evaluated whether selecting only one IC of interest based on its similarity with the average IED field improves MSI in FLE. Methods: MSI was performed with the equivalent current dipole (ECD) technique and two distributed magnetic source imaging (dMSI) approaches: minimum norm estimate (MNE) and coherent Maximum Entropy on the Mean (cMEM). MSI accuracy was evaluated under three conditions: (1) ICA of continuous data (Cont_ICA), (2) ICA at the time of IED (IED_ICA), and (3) without ICA (No_ICA). Localization performance was quantitatively measured as actual distance of the source maximum in relation to the focus (Dmin), and spatial dispersion (SD) for dMSI. Results: After ICA, ECD Dmin did not change significantly (p > 0.200). For both dMSI techniques, ICA application worsened the source localization accuracy. We observed a worsening of both MNE Dmin (p < 0.05, consistently) and MNE SD (p < 0.001, consistently) for both ICA approaches. A similar behaviour was observed for cMEM, for which, however, Cont_ICA seemed less detrimental. Conclusion: We demonstrated that a simplified ICA approach selecting one IC of interest in combination with distributed magnetic source imaging can be detrimental. More complex approaches may provide better results but would be rather difficult to apply in real-world clinical setting. In a broader perspective, caution should be taken in applying ICA for source localization of interictal activity. To ensure optimal and useful results, effort should focus on acquiring good quality data, minimizing artifacts, and determining optimal candidacy for MEG, rather than counting on data cleaning techniques.

Antiproliferative activity of stilbene derivatives and other constituents from the stem bark of Morus nigra L.

The antiproliferative activities of 2',3,4',5,5'-pentahydroxy-cis-stilbene 1, resveratrol 2, oxyresveratrol 3, norartocarpetin 4, kuwanon C 5, morusin 6, cudraflavone A7, kuwanon G 8, albafuran C 9, mulberrofuran G 10, 3-acetyl-O-α-amyrin 11, 3-acetyl-O-ß-amyrin 12, ursolic acid-3-O-acetate 13 and uvaol 14, previously identified from the barks of Morus nigra L., were investigated against HepG2 and MCF-7 cell lines. In addition, a series of methylated stilbenes 15-19 were prepared using compounds 1-3 and their antiproliferative effects were similarly investigated. The structure of a new 2',3,4'-trimethoxy-5-hydroxy-trans-stilbene 19 was elucidated using spectroscopic techniques. It showed remarkable activity against MCF-7 cells with IC50 12.5 µM. However, kuwanon C (5) showed the highest antiproliferative activity with IC50 3.92 and 9.54 µM against MCF-7 and HepG2, respectively.

A new antioxidant stilbene and other constituents from the stem bark of Morus nigra L.

A new stilbene, 2',3,4',5,5'-pentahydroxy-cis-stilbene (1), along with 13 known compounds, resveratrol (2), oxyresveratrol (3), norartocarpetin (4), kuwanon C (5), morusin (6), cudraflavone A (7), kuwanon G (8), albafurane C (9), mulberrofuran G (10), 3-O-acetyl-α-amyrin (11), 3-O-acetyl-ß-amyrin (12) ursolic acid-3-O-acetate (13) and uvaol (14), were isolated from the barks of Morus nigra. Compounds 2, 8, 10, 12 and 14 are reported for the first time from this plant. The isolated compounds were elucidated by means of 1D and 2D NMR, UV, IR and MS, as well as by comparison with the literature data. The isolated compounds and the different extracts were evaluated for their potential antioxidant activity using 2,2'-azino-bis-(3-ethylbenzthiazoline-6-sulfonic acid)(+) radical-scavenging capacity assay and compared with ascorbic acid. The new stilbene (1) exhibited remarkable antioxidant capacity with IC50 of 4.69 µM.

Effect of maternal vitamin A deficiency during pregnancy on neonatal kidney size.

BACKGROUND AND AIMS: In animal studies, vitamin A deficiency (VAD) during pregnancy has been shown to be associated with a decrease in nephron number and kidney weight of the offspring. At present, it is unclear whether these observations are pertinent to humans. Thus, this study was performed to assess the vitamin A status of a cohort of Egyptian pregnant women and their newborns and to determine the potential effect of maternal VAD during pregnancy on the neonatal kidney size. METHODS: The maternal and cord blood samples were collected for the measurement of serum retinol concentration.Within the first 3 days after delivery, an abdominal ultrasound was performed in all newborns to determine the renal dimensions and volume. RESULTS: Sixteen (20%) mothers had VAD. The newborns delivered to VAD mothers had significantly lower mean values of cord retinol concentrations and dimensions of both kidneys than the newborns delivered to mothers with vitamin A sufficiency. The maternal serum retinol concentrations were positively correlated with the cord retinol concentrations, the dimensions of both kidneys, and the combined renal volume of their respective newborns. CONCLUSION: Maternal VAD during pregnancy may decrease renal size in the infant at birth. The functional implications of this effect warrant further study.
