RESUMO

Corticosteroids are crucial for treating inflammatory ocular conditions. The development of dexamethasone revolutionized targeted ocular therapy. Ozurdex, a dexamethasone implant, effectively treats various eye conditions but carries risks such as implant migration. This is a case of anterior segment migration of intravitreal dexamethasone implant, Ozurdex, in a patient with scleral fixation intraocular lens implant in whom conservative management with supine positioning and pharmacologic pupil dilation can help retain the implant back in the vitreous. Patients at high risk of Ozurdex migration should avoid its use. Educate patients on the risk of implant migration and signs of migration to present immediately to an ophthalmology emergency department to avoid corneal damage. It is essential to identify high-risk patients before considering Ozurdex migration. In some cases, conservative management can be initiated while preparing for surgical removal.

RESUMO

BACKGROUND: COVID-19 has been associated with olfactory disturbances in many infected patients. The increase in calcium levels in nasal secretions plays an essential role in the olfactory process with a desensitizing effect on olfactory receptor neurons and negative effects on odor transmission. Calcium chelating agents have the ability to bind calcium in nasal mucus and prevent the negative effects associated with calcium increase. OBJECTIVES: The aim of this work is to demonstrate the intra-nasal topical application of sodium phytate, an environmentally friendly, non-harmful calcium chelating agent, to reduce the adverse effects of calcium on olfactory function and improve olfactory dysfunction according to COVID-19. METHODS: Fifty-two patients with a previous COVID-19 and olfactory dysfunction lasting longer than 90 days were enrolled in a prospective, randomized, blinded, controlled clinical trial. Patients were divided into two equal groups: 26 patients received nasal spray containing 0.9% sodium chloride and 26 patients received nasal spray containing 1% sodium phytate. Olfactory function was measured before treatment and 1 month later using the Sniffin' Sticks test. Calcium content of nasal secretions was determined before and after treatment with an ion-selective electrode. RESULTS: A significant improvement from anosmia to hyposmia was demonstrated after the use of sodium phytate compared with no improvement after the use of sodium chloride. In addition, a decrease in the level of calcium in nasal secretions was observed after the use of sodium phytate. CONCLUSION: Sodium phytate has benefit role on improving the olfactory function after COVID-19.

RESUMO

Cancer is the world's second-leading cause of death. Drug development efforts frequently focus on medicinal plants since they are a valuable source of anticancer medications. A phytochemical investigation of the edible Ziziphus spina-christi (F. Rhamnaceae) leaf extract afforded two new dammarane type saponins identified as christinin E and F (1, 2), along with the known compound christinin A (3). Different cancer cell lines, such as lung cancer (A549), glioblastoma (U87), breast cancer (MDA-MB-231), and colorectal carcinoma (CT-26) cell lines, were used to investigate the extracted compounds' cytotoxic properties. Our findings showed significant effects on all the tested cell lines at varying concentrations (1, 5, 10, and 20 µg/mL). The three compounds exhibited potent activity at low concentrations (< 10 µg/mL), as evidenced by their low IC50 values. To further investigate the complex relationships between these identified cancer-relevant biological targets and to identify critical targets in the pathogenesis of the disease, we turned to network pharmacology and in silico-based investigations. Following this, in silico-based analysis (e.g., inverse docking, ΔG calculation, and molecular dynamics simulation) was performed on the structures of the isolated compounds to identify additional potential targets for these compounds and their likely interactions with various signalling pathways relevant to this disease. Based on our findings, Z. spina-christi's compounds showed promise as potential anti-cancer therapeutic leads in the future.

RESUMO

Aphthous ulcers are very common disorders among different age groups and are very noxious and painful. The incidence of aphthous ulcer recurrence is very high and it may even last for a maximum of 6 days and usually, patients cannot stand its pain. This study aims to prepare a buccoadhesive fast dissolving film containing Corchorus olitorius seed extract to treat recurrent minor aphthous ulceration (RMAU) in addition to clinical experiments on human volunteers. An excision wound model was used to assess the in vivo wound healing potential of Corchorus olitorius L. seed extract, with a focus on wound healing molecular targets such as TGF-, TNF-, and IL-1. In addition, metabolomic profiling using HR-LCMS for the crude extract of Corchorus olitorius seeds was explored. Moreover, molecular docking experiments were performed to elucidate the binding confirmation of the isolated compounds with three molecular targets (TNF-α, IL-1ß, and GSK3). Additionally, the in vitro antioxidant potential of C. olitorius seed extract using both H2O2 and superoxide radical scavenging activity was examined. Clinical experiments on human volunteers revealed the efficiency of the prepared C. olitorius seeds buccal fast dissolving film (CoBFDF) in relieving pain and wound healing of RMAU. Moreover, the wound healing results revealed that C. olitorius seed extract enhanced wound closure rates (p ≤ 0.001), elevated TGF-ß levels and significantly downregulated TNF-α and IL-1ß in comparison to the Mebo-treated group. The phenotypical results were supported by biochemical and histopathological findings, while metabolomic profiling using HR-LCMS for the crude extract of Corchorus olitorius seeds yielded a total of 21 compounds belonging to diverse chemical classes. Finally, this study highlights the potential of C. olitorius seed extract in wound repair uncovering the most probable mechanisms of action using in silico analysis.

RESUMO

Gestational diabetes mellitus (GDM) is the most common complication of pregnancy. The disease is on the rise worldwide with deleterious consequences on the fetus, mother, and children. The study aimed to review the role of lifestyle in the prevention of GDM. We searched PubMed, SCOPUS, Web of Science, Cochrane Library, EBSCO, and Google Scholar from the first published article up to December 2021; articles were eligible if they were controlled trials, prospective cohorts, and case-control. Out of 5559 articles retrieved, 66 full texts were screened, and 19 studies were included in the meta-analysis. (6 studies assessed the effects of diet, and 13 were on exercise). The dietary intervention showed significant positive effect on GDM, odd ratio = 0.69, 95% CI, 0.56-84, P-value for overall effect = 0.002. The DASH diet was better than Mediterranean Diet (odd ratio, 0.71, 95% CI, 68-74, P-value < 0.001). Regarding exercise, no significant prevention was evident on GDM, odd ratio, 0.77, 95% CI, 0.55-1.06, P-value = 0.11. However, a significant prevention of gestational diabetes was found when the exercise was mild-moderate (odd ratio = 0.65, 95% CI, 0.53-80, P < 0.0001) and started in the first trimester (odd ratio, 0.57, 95% CI, 0.43-0.75, P < 0.0001. No significant effect was found when the exercise was vigorous (odd ratio = 1.09, 95% CI, 0.50-2.38, P = 0.83) and started during the second trimester of pregnancy (odd ratio, 1.08, 95% CI, 0.65-1.80, P = 0.77. Diet and early mild-moderate exercise were effective in GDM prevention. Exercise during the second trimester and moderate-vigorous were not. Further studies assessing the type, duration, and frequency of physical activity are needed.

RESUMO

INTRODUCTION: Dyslipidemia is a key clinical abnormality among diabetes mellitus (DM) patients, which heightens their risk of cardiovascular events. Data on the serum lipid profile of type 2 DM (T2DM) patients in Saudi Arabia are scarce. This study therefore aimed to establish dyslipidemia prevalence in a sample of adult T2DM patients in Saudi Arabia and to investigate its associated factors. PATIENTS AND METHODS: A cross-sectional survey was applied to 400 adult T2DM outpatients in attendance at a diabetic center clinic in Tabuk, Saudi Arabia between September 2017 and December 2018 using convenience sampling. Structured questionnaires gathered data relating to the potential risk factors for dyslipidemia. Data on fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) levels were collected from all participants along with their height and weight measurements. Multivariate logistic regression analysis was then used to evaluate the associated risk factors for dyslipidemia. RESULTS: Of the sampled outpatients, 47.8% had high TC levels, 39.0% had high LDL-C, 35.5% had low HDL-C, 42.8% had high TG levels, and 66.5% had a minimum of one abnormal lipid level (dyslipidemia). The risk factors associated with dyslipidemia were an age of >40 years (adjusted odds ratio [AOR] = 1.96, 95% CI 1.19-3.22), irregular exercise (AOR = 2.90, 95% CI 1.21-6.92), a family history of T2DM (AOR = 3.72, 95% CI 2.22-6.23), having had T2DM for >7 years (AOR = 2.42, 95% CI 1.46-3.99), and overweight (AOR = 2.61, 95% CI 1.49-4.58) or obesity (AOR = 2.50, 95% CI 1.24-5.05). CONCLUSION: Dyslipidemia prevalence was found to be high among T2DM patients. Therefore, a compressive mechanism is needed which can screen, treat, and inform them about dyslipidemia and its risk factors, especially modifiable ones such as obesity and exercise.

RESUMO

BACKGROUND: Although the prevalence of type 2 diabetes mellitus (T2DM) is rising sharply in Saudi Arabia, data on glycemic control, crucial to reducing diabetes mellitus complications, remain scarce. This study therefore investigated glycemic control status and the factors influencing poor glycemic control among adult T2DM patients in Saudi Arabia. METHODS: This cross-sectional study examined 423 T2DM patients at a diabetic center in Tabuk, Saudi Arabia between September 2016 and July 2017. Glycemic levels were measured via fasting blood glucose (FBG) levels, and "poor glycemic control" was defined as FBG >130 mg/dL. Poor glycemic control's risk factors were identified using a logistic regression. RESULTS: In the sample, 74.9% of the patients had poor blood glycemic control. Logistic regression revealed that T2DM patients had an increased chance of poorly controlled diabetes if they had family histories of diabetes (adjusted odds ratio [AOR] =7.38, 95% CI 4.09-13.31), longer diabetic durations (AOR =2.33, 95% CI 1.14-4.78 for 5-10 years and AOR =5.19, 95% CI 2.50-10.69 for >10 years), insufficient physical exercise (AOR =19.02, 95% CI 6.23-58.06), or were overweight (AOR =3.79, 95% CI 2.00-7.18), or obese (AOR =5.35, 95% CI 2.72-12.59). CONCLUSION: A high proportion of the sampled patients had poor glycemic control, therefore, health care professionals should manage the associated risk factors to limit disease complications and improve the health of patients with diabetes.

RESUMO

OBJECTIVES: The study aimed to examine the quality of the educational environment in the Faculty of Medicine, University of Tabuk, Saudi Arabia, and to compare between male and female students using the Dundee Ready Educational Environment Measure (DREEM). METHODS: We utilized a cross-sectional survey design.  Participants were 221 medical students (96 males and 125 females) from all classes (1st to 6th year). Each participant responded to a translated version of the DREEM questionnaire that measures five domains: students' perception of learning (SPL), students' perception of teachers (SPT), students' academic self-perception (SASP), students' perception of atmosphere (SPA), and students' social self-perception (SSSP). Numerical differences between male and female students were analyzed using the Student's t-test. RESULTS: The global average score of female students was significantly higher (105.0±22.9, 53% of maximum score) than male students (98.3±24.3, 49% of maximum score; t(219)= -2.119, p= 0.035). The major gender difference was found in the SPT domain, with a higher score in the females (60%) compared to the male (50%) cohort (t (219)= -5.519, p = 0.000). Differences in the other domains were statistically insignificant. Out of the 50 DREEM items, the items that need attention were 32 and 23 on the male and the female sides respectively. CONCLUSIONS: The perception of the educational environment by the female students is significantly better than male students. The study provides valuable information about many educational problems that need attention. DREEM-based surveys are highly recommended for periodic monitoring of the educational environment.
