Introduction: Pulmonary arterial hypertension (PAH) is a life-threatening disease characterized by a sustained rise in mean pulmonary artery pressure. Pulmonary vascular remodeling serves an important role in PAH. Identifying a key driver gene to regulate vascular remodeling of the pulmonary microvasculature is critical for PAH management.
Methods: Differentially expressed genes were identified using the Gene Expression Omnibus (GEO) GSE117261, GSE48149, GSE113439, GSE53408 and GSE16947 datasets. A co-expression network was constructed using weighted gene co-expression network analysis. Novel and key signatures of PAH were screened using four algorithms, including weighted gene co-expression network analysis, GEO2R analysis, support vector machines recursive feature elimination and robust rank aggregation rank analysis. Regulator of G-protein signaling 5 (RGS5), a pro-apoptotic/anti-proliferative protein, which regulate arterial tone and blood pressure in vascular smooth muscle cells. The expression of RGS5 was determined using reverse transcription-quantitative PCR (RT-qPCR) in PAH and normal mice. The location of RGS5 and pericytes was detected using immunofluorescence.
Results: Compared with that in the normal group, RGS5 expression was upregulated in the PAH group based on GEO and RT-qPCR analyses. RGS5 expression in single cells was enriched in pericytes in single-cell RNA sequencing analysis. RGS5 co-localization with pericytes was detected in the pulmonary microvasculature of PAH.
Conclusion: RGS5 regulates vascular remodeling of the pulmonary microvasculature and the occurrence of PAH through pericytes, which has provided novel ideas and strategies regarding the occurrence and innovative treatment of PAH.
Objective: Study on effect of risk factors on over-anticoagulation in patients taking anticoagulant drugs with VKAs (vitamin K antagonists).
Methods: Cross-sectional descriptive, prospective research. Study on 79 patients taking anticoagulant drugs with VKAs who had an INR (International Normalized Ratio) index of more than indicated anticoagulation dose with VKAs therapy.
Results: A total of 79 patients, mean age 65.65 ± 12.17 years [33:85], the elderly group is common (73.4%). Patients had hemorrhage disorders account for 22.8%. The INR index had an average value was 5.88 ± 3.0 [3.02-23.95]; The INR> 5 level group is a higher risk of bleeding than the INR ≤5 level group, it's the statistical significance (p < 0.001). The risk factors such as drugs to treat dyslipidemia, hyperthyroid, amiodarone, beta blocker, prednisone, NSAIDs (Non-steroidal anti-inflammatory), BMI (Body Mass Index), smoke and alcohol that the risk factors of increasing of bleeding when receiving anticoagulants but it's not statistically significant yet (OR >1, p > 0.05); These patients using coenzyme Q10 and green vegetable nutrition such as cruciferous vegetables (Brassicaceae, Asteraceae) are quite common (31.6% and 35.4%), its effect on coagulation with vitamin K and cause of the increased in risk of bleeding was statistical significantly with OR = 5.28 (CI: 1.72-16.17, p < 0.01), and OR = 2.99 (CI: 1.01-8.80, p < 0.05) respectively.
Conclusion: Most patients in over-anticoagulation were the elderly group. Patients had hemorrhage disorders account for 22.8%. The INR> 5 level group was a higher risk of bleeding than the INR ≤5 level group with statistical significance. Patients using Coenzyme Q10 and green vegetable nutrition such as cruciferous vegetables (Brassicaceae, Asteraceae) are quite common, its effect on coagulation and cause of the increased risk of bleeding complication with statistical significance.
Background: Hospital-acquired thrombosis (HAT) is associated with significant morbidity, mortality, and financial burden globally. Following trusted guidelines for VTE prevention has shown effective, safe, and satisfactory results. This prompts national collaborative efforts to maintain a consensus approach for the safe risk assessment of inpatients and the prescription of thromboprophylaxis.
Objective: This study aimed to detect and estimate deviations from international thromboprophylaxis protocols. The study also aimed to raise the quality of practice and adherence to evidence-based protocols in Alshuhada Teaching Hospital.
Methods: A cross-sectional audit of general surgical inpatients was performed from October 2021 to May 2022. The first cycle was from 1/10/2021 to 21/10/2021, and the second cycle was from 13/5/2022 to 31/5/2022. The target population was adults aged >18 years. Data were collected via an online checklist on two separate occasions. The criteria were based on the NICE guideline for venous thromboembolism in individuals aged over 16 years: "Reducing the risk of hospital-acquired deep vein thrombosis or pulmonary embolism NG89".
Results: Forty-five surgical inpatients were included in this study: 20 in the first cycle and 25 in the second cycle. The first-cycle report showed that only 25% of VTE candidates received this regimen. In the second cycle, practice significantly improved, with 92% of admitted patients having their risk assessment tool completed within 24 h of admission. 79% of VTE prophylaxis candidates were prescribed adequate pharmacological prophylaxis within 14 h of admission.
Conclusion: The rate of adequate thromboprophylaxis for inpatients undergoing surgery was very low before clinicians received education on VTE prevention, whereas was evidently high after they had received them. The cause of non-adherence in the pre-intervention phase was a lack of adequate knowledge regarding the magnitude and burden of HAT and the importance of thromboprophylaxis, which has a potential role in preventing the majority of HAT.
Background: Acute Coronary Syndrome is the leading cause of morbidity and mortality in developing nations including Ethiopia. As frontline healthcare providers, nurses need to be prudent in handling cases of acute coronary syndrome. However, nurses' knowledge and practice of acute coronary syndrome are not well-known across Ethiopia. Thus, this study aimed to assess knowledge, practice, and associated factors regarding the care of acute coronary syndrome among acute care nurses working at selected hospitals in Addis Ababa, Ethiopia.
Methods: Institution-based descriptive cross-sectional study design was conducted from February to March among 252 purposively selected nurses working in tertiary hospitals of Addis Ababa, Ethiopia. A pretested and structured questionnaire was used for data collection. Data were entered into Epi-Data 4.6 and exported to SPSS version 25. Both descriptive and inferential statistics were used to describe and test the association between selected variables. P-values < 0.05 were declared as significant factors for the outcome variable.
Results: Out of 252 nurses, (52%) had good knowledge, and (44.4%) had good practice towards care of Acute Coronary Syndrome. Being a master's degree [AOR=3.801, (95% CI:1.314-10.996), P =0.014] and having guidelines [AOR= 10.998, (95% CI:2.478-48.805), P =0.002] were significantly associated with nurse's good knowledge of ACS. While having a master's degree [AOR=4.258, (95% CI:1.676-10.820), P=0.002] and getting in-service training [AOR= 1.902, (95% CI:1.022-3.539), P = 0.042] were significantly associated with nurse's good level of practice.
Conclusion: In this study, nurses had inadequate knowledge and practice regarding the care of Acute Coronary Syndrome. Nurses' educational level, presence of clinical practice guidelines, and getting training were determinant factors associated with good knowledge and practice. Therefore, organizational and nursing educational support are needed to improve this gap by providing short- and long-term training, and updated evidence-based clinical practice guidelines should be available for all acute care nurses.
