This study aims to investigate the effect of hydroethanolic extracts of Cynara scolymus (C. scolymus) leaf (CLHE) and C. scolymus flower (CFHE) on the hepatic histopathological lesions and functional biochemical changes induced by type 2 diabetes mellitus (T2DM). The rat model of T2DM was induced by intraperitoneal injection of streptozotocin (STZ) in a dose of 60 mg/kg for 15 minutes following nicotinamide (NA) (60 mg/kg). The rats were allocated into four groups: group 1 (negative control), group 2 (diabetic control), group 3 (diabetic rats supplemented with 100 mg/kg/day CLHE), and group 4 (diabetic rats supplemented with 100 mg/kg/day CFHE). Treatment with CLHE and CFHE, for the study duration of 28 days, significantly improved the deteriorated hepatic glycogen content, glycogen phosphorylase, glucose‐6‐phosphatase activities, serum fructosamine levels, lipid profile, aspartate transaminase activities, and alanine transaminase activities as well as serum insulin and C‐peptide levels. The elevated liver lipid peroxidation and the decreased activities of superoxide dismutase and glutathione peroxidase were significantly alleviated. The elevated expression of the proinflammatory cytokine tumor necrosis factor‐α in the liver of diabetic rats was significantly reduced by treatments with CLHE and CFHE. NA/STZ‐induced T2DM exhibited hepatic histopathological changes in the form of disordered hepatocytes, cytoplasm dissolution, and mononuclear leukocytic infiltration. The electron microscopic ultrastructure study revealed damaged mitochondria with ill‐defined cristae and fragmentation of the rough endoplasmic reticulum. Treatments with CLHE and CFHE remarkably amended these histopathological and EM ultrastructural changes. In conclusion, both CLHE and CFHE may have antidiabetic and improvement effects on the liver function and structural integrity, which may be mediated, at least in part, via suppression of inflammation and oxidative stress and enhancement of the antioxidant defence system.

Diabetes-related distress (DRD) is a psychological syndrome with worsened prognosis in uncontrolled diabetic patients. The current study aimed to assess the factors contributing to DRD among the Lebanese population using the Diabetes Distress Scale (DDS-17) score and its sub-scores. A cross-sectional analysis was conducted between March and September 2021 enrolling. 125 diabetic from six Lebanese governorates through an online survey. The survey included two parts: the first section gathered sociodemographic data sociodemographic and socioeconomic data and the second one focused on assessing the Diabetes Distress Scale (DDS-17) score. Participants 30 years old and above had higher emotional distress compared to younger patients, (65.2 % versus 45.5 %). Those with a primary educational level showed significantly higher emotional distress than those with a secondary and tertiary level of education (72.5 %, versus 66.7 % and 46.4 %). Participants who were treated with both insulin and non-insulin medications or had a diastolic blood pressure of more than 90 mmHg showed significantly moderate to high distress (63.6 % or 53.8 %). Participants who lived in rural areas showed higher distress (35.6 %). Obese and overweight had significant moderate to high distress (64.1 %, and 48.0 %). The same results were found in non-married (divorced or widowed) and married participants (76.9 % and 51.3 %). The association between medical history with total distress showed that participants with glycemic store HbA1c of more than 6.5 followed by those who had HbA1c between 5.7 and 6.4 showed moderate to high total distress (45.9 % and 40.0 %). It is concluded that the prevalence of DRD is high in Lebanon, more common among rural residents, and among participants high HbA1c, low educational level, unmarried and on complex treatment regimens. Screening for DRD and providing better support can optimize clinical outcomes.

Background and Objectives: Rosiridin is a monoterpene with outstanding monoamine inhibitory activity that is useful to treat depressive episodes and rapid-onset dementia. The current investigation aims to evaluate the neurologically protective impact of rosiridin, which opposes aluminum chloride (AlCl3) and causes memory dysfunction in rats. Materials and Methods: Memory impairment was developed in Wistar rats by administering AlCl3 (100 mg/kg p.o.) orally for 42 days and then supplemented with rosiridin at 10 and 20 mg/kg/p.o. Upon completion of the investigation, the behavior factor was performed utilizing the Y-maze, Morris Water Maze, and open field tests. Estimating numerous biological factors, such as nitric oxide (NO), oxidative stress (malondialdehyde MDA), acetylcholinesterase (AChE), butyrylcholinesterase levels (BuChE), antioxidants (glutathione GSH, catalase CAT, and superoxide dismutases SODs) and neurotransmitter (serotonin-5HT, dopamine-DA, acetylcholine-Ach) in the brain. Furthermore, interleukin-6 (IL-6), IL-1β, tumor necrosis factor (TNF-α), brain-derived neurotrophic factor (BNDF), nuclear factor kappa B (NFᴋB), phosphatidylinositol 3-kinase (PI3K), and pAkt were assessed in the diffused brain cells. Results: The rosiridin-treated group significantly improved in terms of behavioral parameters, including in the Y-maze, Morris Water Maze, and open field tests. Further, rosiridin restored biochemical parameters, including NO, oxidative stress AChE, BuChE, antioxidants, neurotransmitters, IL-6, IL-1β, TNF-α, BNDF, NFᴋB, PI3K, and pAkt compared to AlCl3. Conclusions: The current investigation reveals that rosiridin could ameliorate the impairment of memory that AlCl3 causes in rats via improvements in behavioral and restored biochemical parameters.

Background: Ischemic heart disease (CAD), a leading global health burden, arises primarily from atherosclerosis, an inflammatory condition characterized by lipid accumulation and metabolic dysregulation. The precise contribution of inflammatory cytokines (IL-2, IL-6, and TNF-α) to CAD pathogenesis remains an area of significant research. Aim: The primary aim of this study is to examine the IL-2, IL-6, and TNF-α in patients with coronary artery disease (CAD) and compare them with Non-CAD individuals to evaluate their potential as diagnostic biomarkers for CAD. Methodology: A prospective observational study was conducted over 3 years, involving 100 participants divided into CAD and non-CAD groups. Blood samples were isolated and analyzed for IL-2, IL-6, and TNF-α levels utilizing ELISA kits. Biochemical parameters, including lipid profiles, were also assessed. Results: This study observed significantly elevated IL-6 in patients with CAD compared with controls, while IL-2 and TNF-α levels did not reach statistical significance. The CAD group exhibited dyslipidemia characterized by elevated triglycerides and reduced HDL. Furthermore, the CAD group demonstrated alterations in biochemical parameters, including lower albumin and calcium levels, higher urea and uric acid levels, and an elevated erythrocyte sedimentation rate. These findings suggest a systemic inflammatory state and metabolic disturbances in patients with CAD. Conclusions: This study highlights IL-6 as a potential biomarker and key player in CAD pathogenesis. These findings warrant further investigation into the therapeutic potential of targeting inflammatory pathways for cardiovascular risk reduction.

Background: Globally, many women express the desire to avoid immediate pregnancy for 24 months postdelivery, and only forty percent use contraceptives during this period. There is an enormous demand for postpartum family planning, particularly in developing countries with low- or middle-income grades. Postpartum intrauterine devices such as long-acting reversible contraceptives (LARCs) are among the most effective methods of family planning in the immediate postpartum period, yet their effectiveness is hindered because of a lack of availability and training. Strategies to increase access to LARCs are essential. Hence, the purpose of the current study is to determine the barriers among healthcare providers in providing immediate postpartum family planning services. Methods: A cross-sectional study was conducted in the Department of Obstetrics and Gynaecology at SIMS, a tertiary care teaching hospital, from January to March 2024. Approximately 293 healthcare providers who fulfilled the inclusion criteria were provided an online questionnaire in the form of a Google Forms link, which included a structured questionnaire focusing on various aspects, including demographics, knowledge, practices, and barriers in their practice. The data collected were analysed through SPSS version 26, which employs chi-square tests and Pearson’s correlation to determine any significant associations among them. Based on the key statistical outcomes and the significant correlations observed related to the data, a thematic analysis through SWOT (strengths, weaknesses, opportunities, threats) was conducted. The study adhered to the method outlined by Braun and Clarke (2006) and compiled with the COREQ (consolidated criteria for reporting qualitative research) checklist to uphold methodological integrity. Results: Among the participants, 92.4% provided family planning counselling after childbirth, predominantly during the antenatal period (75.1%), and the provision of immediate postnatal family planning was reported in 76.1% of the participants, with PPIUDs identified as the most utilized method by 52.6%. Various barriers were identified, including insufficient training on Implanon (33.4%) and the PPIUCD (12.6%), the unavailability of implants (59.0%), and a lack of interest among patients (46.1%). Statistically significant associations were observed between the practice setting and knowledge of postpartum family planning (p = 0.002), as well as deficiencies in training for the PPIUCD (p < 0.001). The study highlights the place of practice and the practitioners’ experience as significant strengths in offering immediate postpartum contraception and referring patients for family planning. However, qualification was identified as a limiting factor for practicing immediate postpartum family planning. Conclusions: This study revealed significant difficulty in delivering prompt postpartum long-acting reversible contraceptives (LARCs), underscoring the necessity of improved education and training for professionals. Focusing on these challenges is important in enhancing postpartum family planning acceptance and decreasing unfulfilled requirements in resource-limited settings.

Background: Epilepsy is defined by an excessive level of activity in the neurons and coordinated bursts of electrical activity, resulting in the occurrence of seizure episodes. The precise cause of epileptogenesis remains uncertain; nevertheless, the etiology of epilepsy may involve neuroinflammation, oxidative stress, and malfunction of the neurotransmitter system. Objective: The goal of this investigation was to assess barbaloin’s protective properties with respect to pentylenetetrazol (PTZ)-)-induced cognitive deficits in rats via antioxidative, anti-inflammatory, and neurotransmitter-modulating effects. Methods: Wistar rats were subjected to PTZ [40 mg/kg (i.p.)], which induced cognitive decline. Behavior assessment using a kindling score, open-field test (OFT), novel object recognition test (NORT), and assays for superoxide dismutase (SOD), reduced glutathione (GSH), catalase (CAT), malondialdehyde (MDA), acetylcholinesterase (AChE), caspase-3, nitric oxide (NO), interleukins-1β (IL-1β), tumor necrosis factor-α (TNF-α), IL-6, nuclear factor kappa-B (NF-κB), Bcl-2 and Bax, and neurotransmitter levels [GABA, DA, NE, and serotonin (5-HT)] were performed. Results: The treatment of rats with barbaloin resulted in behavior improvement and significant changes in the levels of GSH, SOD, CAT, MDA, AChE, NO, IL-6, IL-1β, TNF-α, NF-κB, caspase-3, Bcl-2, and Bax compared to the PTZ control group. Barbaloin treatment resulted in notable changes in neurotransmitter levels (GABA, NE, 5-HT, DA) compared to the PTZ group. Conclusions: The ongoing study has gathered evidence indicating that the injection of barbaloin has resulted in significant improvements in cognitive performance in rats. This is achieved by inhibiting oxidative stress, enhancing the activity of natural antioxidant enzymes, reducing cytokine levels, and increasing the levels of neurotransmitters in the brain. These results were detected in comparison to a PTZ control and can be attributed to the potent anti-inflammatory and antioxidant capabilities of barbaloin, which could be linked to its neuroprotective properties. Barbaloin may potentially increase cognitive decline and boost neuronal survival by altering the expression of Bax, caspase-3, Bcl-2.
