RESUMO

BACKGROUND: Pre-eclampsia and eclampsia are the leading causes of perinatal morbidity and mortality worldwide. Early detection and treatment of preeclampsia is lifesaving; however, evidence suggests that the majority of women in low and middle income-countries are not routinely screened for high blood pressure during antenatal care, that those with severe and mild pre-eclampsia are not monitored for blood pressure and proteinuria as needed, and the magnesium sulphate is not administered as needed. The purpose of this study was therefore to assess knowledge and skills in pre-eclampsia and eclampsia management and their associated factors among healthcare providers working in antenatal clinics in Zanzibar. METHODS: This was a cross-sectional analytical study conducted in all levels of healthcare facilities in Zanzibar. The study involved 176 healthcare providers (nurses and doctors) who were randomly selected. A self-administered questionnaire was used to collect data and descriptive and inferential statistics were used in the analysis whereby logistic regression models were employed. The Chi-square coefficient, odds ratio, and 95% confidence intervals were reported, and the level of significance was set at p < 0.05. RESULTS: The mean age of healthcare providers was 35.94 (SD ± 7.83) years. The proportion of healthcare providers with adequate knowledge was 49.0%, and 47% had adequate skills. Knowledge level was predicted by working in higher healthcare facility levels (AOR: 3.28, 95% CI: 1.29-8.29), and having attended on-the-job training on pre-eclampsia (AOR: 7.8, 95% CI: 2.74 - 22.75). Skills were predicted by having attended on-job training (AOR: 8.6, 95% CI: 2.45 - 30.16), having working experience of five years or above in antenatal care units (AOR: 27.89, 95% CI: 5.28 - 148.89) and being a medical doctor or assistant medical doctor (AOR: 18.9, 95% CI: 2.1-166). CONCLUSION: Approximately half of Zanzibar's ANC healthcare workers demonstrated inadequate knowledge and skills in preeclampsia care, indicating a critical need for targeted interventions to reduce maternal morbidity and mortality. Knowledge is predicted by attending on-the-job training and working in higher healthcare facility level, while skills is predicted by attending on job training, more years of working experience in antenatal care units and being a medical doctor or assistant medical doctor The study recommends the healthcare facility institutions to provide on-the-job training to for the healthcare providers working in lower healthcare facility levels.

RESUMO

Dipeptidyl peptidase-4 (DPP-IV) inhibitors are known as safe and well-tolerated antidiabetic medicine. Therefore, the aim of the present work was to synthesize some carbohydrazide derivatives (1a-5d) as DPP-IV inhibitors. In addition, this work involves simulations using molecular docking, ADMET analysis, and Lipinski and Veber's guidelines. Wet-lab synthesis was used to make derivatives that met all requirements, and then FTIR, NMR, and mass spectrometry were used to confirm the structures and perform biological assays. In this context, in vitro enzymatic and in vivo antidiabetic activity evaluations were carried out. None of the molecules had broken the majority of the drug-likeness rules. Furthermore, these molecules were put through additional screening using molecular docking. In molecular docking experiments (PDB ID: 2P8S), many molecules displayed more potent interactions than native ligands, exhibiting more hydrogen bonds, especially those with chloro- or fluoro substitutions. Our findings indicated that compounds 5b and 4c have IC50 values of 28.13 and 34.94 µM, respectively, under in vitro enzymatic assays. On the 21st day of administration to animals, compound 5b exhibited a significant reduction in serum blood glucose level (157.33 ± 5.75 mg/dL) compared with the diabetic control (Sitagliptin), which showed 280.00 ± 13.29 mg/dL. The antihyperglycemic activity showed that the synthesized compounds have good hypoglycemic potential in fasting blood glucose in the type 2 diabetes animal model (T2DM). Taken all together, our findings indicate that the synthesized compounds exhibit excellent hypoglycemic potential and could be used as leads in developing novel antidiabetic agents.

RESUMO

This review summarized the current breakthroughs in the chemistry of acridines as anti-cancer agents, including new structural and biologically active acridine attributes. Acridine derivatives are a class of compounds that are being extensively researched as potential anti-cancer drugs. Acridines are well-known for their high cytotoxic activity; however, their clinical application is restricted or even excluded as a result of side effects. The photocytotoxicity of propyl acridine acts against leukaemia cell lines, with C1748 being a promising anti-tumour drug against UDP-UGT's. CK0403 is reported in breast cancer treatment and is more potent than CK0402 against estrogen receptor-negative HER2. Acridine platinum (Pt) complexes have shown specificity on the evaluated DNA sequences; 9-anilinoacridine core, which intercalates DNA, and a methyl triazene DNA-methylating moiety were also studied. Acridine thiourea gold and acridinone derivatives act against cell lines such as MDA-MB-231, SK-BR-3, and MCF-7. Benzimidazole acridine compounds demonstrated cytotoxic activity against Dual Topo and PARP-1. Quinacrine, thiazacridine, and azacridine are reported as anti-cancer agents, which have been reported in the previous decade and were addressed in this review article.

RESUMO

Hypertensive disorders of pregnancy are reported as the second leading root of maternal morbidity and mortality in Zanzibar. Evidence shows that the majority of pregnant women in Zanzibar are referred late from lower-level healthcare facilities, and majority develop complications of eclampsia. This study's goal is to determine if all public healthcare facilities in Zanzibar are prepared to manage pre-eclampsia cases and if lower-levels public healthcare facilities are ready to refer pre-eclampsia cases. This will be a descriptive cross-sectional study that will involve a total of 54 healthcare facilities and 176 health care providers working in antenatal clinics. All public health care facilities will be stratified into tertiary, secondary, and primary strata. A simple random sampling will be used to select 46 healthcare facilities in the primary stratum while all healthcare facilities within the tertiary and secondary strata will be selected. In each healthcare facility, a physical observation will be performed to assess the availability of equipment and supplies, medications, and lab tests, while a self-administered questionnaire will be used to assess the knowledge level and skills of healthcare providers for the management of pre-eclampsia and eclampsia. Patient's case files in the tertiary and secondary strata will be reviewed to assess the quality of management of pre-eclampsia while the service records of the primary stratum will be assessed for compliance status with referral guidelines. Data will be analyzed using SPSS version 25. Descriptive statistics will be used to describe the frequency distribution of the study variables, and results will be presented in terms of frequency and percentage. The Chi-square test will be used to describe the relationship between variables, and a p-value of < 0.05 will be regarded as a statistically significant difference.

RESUMO

Alzheimer's disease (AD) is the most common cause of dementia and cognitive impairment; yet, there is currently no treatment. A buildup of Aß, tau protein phosphorylation, oxidative stress, and inflammation in AD is pathogenic. The accumulation of amyloid-beta (Aß) peptides in these neurocognitive areas is a significant characteristic of the disease. Therefore, inhibiting Aß peptide aggregation has been proposed as the critical therapeutic approach for AD treatment. Resveratrol has been demonstrated in multiple studies to have a neuroprotective, anti-inflammatory, and antioxidant characteristic and the ability to minimize Aß peptides aggregation and toxicity in the hippocampus of Alzheimer's patients, stimulating neurogenesis and inhibiting hippocampal degeneration. Furthermore, resveratrol's antioxidant effect promotes neuronal development by activating the silent information regulator-1 (SIRT1), which can protect against the detrimental effects of oxidative stress. Resveratrol-induced SIRT1 activation is becoming more crucial in developing novel therapeutic options for AD and other diseases that have neurodegenerative characteristics. This review highlighted a better knowledge of resveratrol's mechanism of action and its promising therapeutic efficacy in treating AD. We also highlighted the therapeutic potential of resveratrol as an AD therapeutic agent, which is effective against neurodegenerative disorders.
