Background/Aim: Cervical cancer remains a major public health concern. The ratio of CD4+:CD8+ T-cells is used to evaluate the immune system function. This study aimed to explore the CD4+:CD8+ T-cell ratio in relation to the glycemic status, inflammatory markers, vitamin D, and vitamin B12 in patients with early diagnosed cervical cancer. Patients and Methods: This is a cross-sectional study. Blood samples were collected for flow cytometry analysis. Information regarding Papanicolaou (Pap) smears and colposcopy investigations were collected from 152 women with type 2 diabetes admitted to East Jeddah Hospital, Jeddah, Saudi Arabia, between January 2018 and January 2021. Results: Patients with early cervical carcinoma and a higher CD4+:CD8+ ratio (>1.2) had a higher C-reactive protein (CRP) level than those with a lower CD4+:CD8+ ratio (Mean±SD=13.75±13.3 vs. 10.85±8.1; p-value=0.034). Patients with early cervical carcinoma, diabetes, and higher CD4+:CD8+ ratio (>1.2) had a higher blood HbA1c percent than those with a lower CD4+:CD8+ ratio. Conclusion: A high CD4+:CD8+ T-cells ratio was associated with an increased HbA1c% and CRP levels in women with diabetes diagnosed with early cervical carcinoma, which can induce inflammation in early diagnosed patients with cervical cancer.

The aim of this study was to evaluate renal function by urinalysis in COVID-19 patients following the administration of vancomycin.A retrospective observational study was performed between October 2020 and January 2021, during which time patients were hospitalized in the Prince Mohammed Bin Abdulaziz Hospital in Riyadh, Saudi Arabia. The patients were free of kidney disease. Urinalysis was performed by an automated laboratory system, and the collected results were based upon age, gender, diabetic status, whether the patients had received vancomycin, the mortality rate, and the urinalysis panel including coinfection by bacteria and yeast.A total of 227 patients were included in this study, 147 (64.75%) of whom were male and 80 (35.25%) of whom were female; 54.63% were diabetic, 11.89% were prediabetic, and 33.48% were non-diabetic patients. Proteinuria, hematuria, glycosuria, coinfection, and ketonuria were detected among all participants within the study group, specifically among diabetic patients. The mortality rate was 16.2% among the study group; 6.6% had re-ceived vancomycin, and 9.6% had not received vancomycin. No significant correlation was found between nephrotoxicity and abnormalities in the urine and the mortality rate among members of our study group.Proteinuria, hematuria, glycosuria, ketonuria, and coinfection were common among members of our study group, especially in the diabetic group. Urinalysis abnormalities were less frequent in the vancomycin group than in the others, except the prediabetic group. No correlation between mortality and vancomycin was identified.

This study evaluates the seroprevalence of immunoglobulin M (IgM) and G (IgG) antibodies against SARS-CoV-2 after two doses of Pfizer-BioNTech COVID-19 vaccination from women with breast cancer in Jazan city Kingdom of Saudi Arabia, antibody detections were performed one month and three months after the administration of the second dose.Overall, 103 breast cancer patients were included. Individuals who had had two doses of Pfizer-BioNTech vaccine, patients who were earlier diagnosed with COVID-19 infection, had not finalized immunization plan, or who received the second dose recently were excluded from the study. The antibodies detection test was run according to the manufacturer's directions of Viva Diag™ SARS-CoV-2 IgM/IgG Rapid Test (COVID-19 IgM/IgG Rapid Test).This study included 62 (60.2%) and 41 (39.8%) patients with invasive ductal carcinoma and invasive lobular carcinoma, respectively. The age, median and interquartile range (IQR) was 54.0 (26) years. Regarding reactivity of antibodies, after one month IgM antibody showed 64 (62.1%) positive and 39 (37.9%) negative while IgG antibody showed positive results in all patients. After three months IgM antibody showed 44 (42.7%) positive and 59 (57.3%) negative, while IgG showed 87 (84.5%) positive and 16 (15.5%) negative. There were significant differences in the IgM and IgG seropositivity. There were 19.3% patients with ductal carcinoma who were positive and then turned negative versus 17.7% who were positive and then turned negative, respectively (p0.001). There were significant differences in IgM antibody positivity among different age groups.Our results recommend the importance of screening for an antibody response for breast cancer patient after immunization in order to reveal persons who need early and late extra enhancing vaccine dose. Upcoming studies recommended to estimate different methods that raise cancer patients' immune response.

Alzheimer’s disease is the commonest form of dementia associated with short-term memory loss and impaired cognition and, worldwide, it is a growing health issue. A number of therapeutic strategies have been studied to design and develop an effective anti-Alzheimer drug. Curcumin has a wide spectrum of biological properties. In this regard, the antioxidant potentials of mono-carbonyl curcumin analogues (h1–h5) were investigated using in vitro antioxidant assays and hippocampal-based in vivo mouse models such as light–dark box, hole board, and Y-maze tests. In the in vitro assay, mono-carbonyl curcumin analogues h2 and h3 with methoxy and chloro-substituents, respectively, showed promising 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2′-azinobis-3-ethylbenzothiazo-line-6-sulfonate (ABTS) free radical scavenging activities. In the in vivo studies, scopolamine administration significantly (p < 0.001) induced oxidative stress and memory impairment in mice, in comparison to the normal control group. The pretreatment with mono-carbonyl curcumin analogues, specifically h2 and h3, significantly decreased (123.71 ± 15.23 s (p < 0.001), n = 8; 156.53 ± 14.13 s (p < 0.001), n = 8) the duration of time spent in the light chamber and significantly enhanced (253.95 ± 19.05 s (p < 0.001), n = 8, and 239.57 ± 9.98 s (p < 0.001), n = 8) the time spent in the dark compartment in the light–dark box arena. The numbers of hole pokings were significantly (p < 0.001, n = 8) enhanced in the hole board test and substantially increased the percent spontaneous alternation performance (SAP %) in the Y-maze mouse models in comparison to the stress control group. In the biomarker analysis, the significant reduction in the lipid peroxidation (MDA) level and enhanced catalase (CAT), superoxide dismutase (SOD), and glutathione (GSH) activities in the brain hippocampus reveal their antioxidant and memory enhancing potentials. However, further research is needed to find out the appropriate mechanism of reducing oxidative stress in pathological models.

Depression is a serious psychiatric disorder that affects millions of individuals all over the world, thus demanding special attention from researchers in order to investigate its effective remedies. Curcumin, along with its synthetic derivatives, is recognized for its incredible pharmacological activities. In this study, methyl, methoxy and chloro-substituent synthetic curcumin analogues C1–C3 were respectively tested for free radical-scavenging activity. Behavioral studies were performed using chemical-induced and swimming endurance tests as stress models, and forced swim tests (FSTs) and tail suspension tests (TSTs) as depression mice models. Biochemical examinations were performed after a scopolamine-induced stress model by decapitating the mice, and brain tissues were isolated for biochemical assessment of catalase (CAT), superoxide dismutase (SOD), glutathione (GSH), and malondialdehyde (MDA). The curcumin analogue C2 exhibited higher DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2′-azinobis-3-ethylbenzothiazo-line-6-sulphonate) free radical-scavenging potential, having IC50 values of 45.18 µg/mL and 62.31 µg/mL, respectively, in comparison with reference curcumin and tocopherol. In the chemical-induced test, C2 (80.17%), C3 (72.79%) and C1 (51.85%) revealed higher antistress responses by significantly reducing the number of writhes, whereas the immobility time was significantly reduced by C2 and C3 in the swimming endurance test, indicating excellent antistress potential. Similarly, C2 and C3 significantly reduced the immobility times in FST and TST, demonstrating their antidepressant properties. The biomarkers study revealed that these compounds significantly enhanced hippocampus CAT, SOD and GSH, and reduced MDA levels in the scopolamine-induced stress mice model. These findings suggest the potential of curcumin analogues (C2 and C3) as antistress and antidepressant agents.
