Non-Coding RNA-Mediated Gene Regulation in Cardiovascular Disorders: Current Insights and Future Directions.

Cardiovascular diseases (CVDs) pose a significant burden on global health. Developing effective diagnostic, therapeutic, and prognostic indicators for CVDs is critical. This narrative review explores the role of select non-coding RNAs (ncRNAs) and provides an in-depth exploration of the roles of miRNAs, lncRNAs, and circRNAs in different aspects of CVDs, offering insights into their mechanisms and potential clinical implications. The review also sheds light on the diverse functions of ncRNAs, including their modulation of gene expression, epigenetic modifications, and signaling pathways. It comprehensively analyzes the interplay between ncRNAs and cardiovascular health, paving the way for potential novel interventions. Finally, the review provides insights into the methodologies used to investigate ncRNA-mediated gene regulation in CVDs, as well as the implications and challenges associated with translating ncRNA research into clinical applications. Considering the broader implications, this research opens avenues for interdisciplinary collaborations, enhancing our understanding of CVDs across scientific disciplines.

Impact of Coronavirus Diseases on Liver Enzymes.

Introduction Coronavirus disease 2019 (COVID-19) affects various organs including lungs, brain, and eyes. Very limited data is available related to the effect of COVID-19 on liver. This study is conducted to determine the impact of COVID-10 on liver by measuring the frequency of participants with deranged liver enzymes in patients diagnosed with COVID-19. Methods This cross-sectional study was conducted in a COVID-19 unit of a tertiary care hospital in Pakistan from February 2021 to June 2021. A total of 900 patients admitted with COVID-19 were enrolled in the study after seeking informed consent. After enrollment, taking history and vitals, 5 mL blood was drawn via phlebotomy and sent to the laboratory to test for C-reactive protein, lactate dehydrogenase, and liver enzymes. Results Overall 141 (28.2%) participants had a minimum of one deranged liver enzyme. The most commonly deranged liver enzyme found was alanine transaminase (ALT), both in males (19.9%) and females (21.3%), followed by aspartate transaminase (male: 18.3% and female: 20.3%). Serum total bilirubin was deranged in both males (8.4%) and females (8.3%). There was no significant difference in the gender-wise prevalence of deranged liver enzymes.  Conclusion Liver enzymes are frequently deranged in patients admitted with COVID-19. Liver enzymes should be regularly monitored during the course of management of COVID-19, as various medications used in the treatment of COVID-19 may further deteriorate liver enzymes and may cause long-term damage.

Dysnatremia is a Predictor for Morbidity and Mortality in Hospitalized Patients with COVID-19.

CONTEXT: Dysnatremia is an independent predictor of mortality in patients with bacterial pneumonia. There is paucity of data about the incidence and prognostic impact of abnormal sodium concentration in patients with coronavirus disease 2019 (COVID-19). OBJECTIVE: This work aimed to examine the association of serum sodium during hospitalization with key clinical outcomes, including mortality, need for advanced respiratory support and acute kidney injury (AKI), and to explore the role of serum sodium as a marker of inflammatory response in COVID-19. METHODS: This retrospective longitudinal cohort study, including all adult patients who presented with COVID-19 to 2 hospitals in London over an 8-week period, evaluated the association of dysnatremia (serum sodium < 135 or > 145 mmol/L, hyponatremia, and hypernatremia, respectively) at several time points with inpatient mortality, need for advanced ventilatory support, and AKI. RESULTS: The study included 488 patients (median age, 68 years). At presentation, 24.6% of patients were hyponatremic, mainly due to hypovolemia, and 5.3% hypernatremic. Hypernatremia 2 days after admission and exposure to hypernatremia at any time point during hospitalization were associated with a 2.34-fold (95% CI, 1.08-5.05; P = .0014) and 3.05-fold (95% CI, 1.69-5.49; P < .0001) increased risk of death, respectively, compared to normonatremia. Hyponatremia at admission was linked with a 2.18-fold increase in the likelihood of needing ventilatory support (95% CI, 1.34-3.45, P = .0011). Hyponatremia was not a risk factor for in-hospital mortality, except for the subgroup of patients with hypovolemic hyponatremia. Sodium values were not associated with the risk for AKI and length of hospital stay. CONCLUSION: Abnormal sodium levels during hospitalization are risk factors for poor prognosis, with hypernatremia and hyponatremia being associated with a greater risk of death and respiratory failure, respectively. Serum sodium values could be used for risk stratification in patients with COVID-19.

Silybum marianum (milk thistle) improves vancomycin induced nephrotoxicity by downregulating apoptosis.

Increased use of vancomycin for treating infections, and the associated risk of causing nephrotoxicity lead to the present study. The antioxidant and anti-apoptotic potential of Silybum marianum is used along with vancomycin to reduce adverse effects on the kidney. Vero cells (monkey kidney cells) and mice were used to test S. marianum extract on vancomycin induced nephrotoxicity. Vero cells were treated with different concentrations of vancomycin and S. marianum for 24 h for determination of cytotoxic potential and mRNA levels of apoptotic genes p53 , p21, and cyt-c were measured. For in-vivo studies mice were divided into five groups; G1 control (untreated), G2 vehicle (olive oil), G3 vancomycin treated (300 mg/kg body weight), G4 (S. marianum; 400 mg/kg bodyweight and vancomycin 300 mg/kg bodyweight simultaneously) and G5 (S. marianum 400 mg/kg bodyweight and vancomycin 300 mg/kg bodyweight treatment started after day 4 of S. marianum treatment). After 10 days histopathological analysis of mice kidneys was performed, serum urea and creatinine were analysed and mRNA expression of p53 , p21, and cyt-c was evaluated. Expression of p53, p21, and cyt-c in Vero cells was elevated in response to vancomycin treatment, whereas after S. marianum administration expression of these genes reduced. Vancomycin showed apoptosis in cells at the concentration of 6 mg/ml (LC50). Urea and creatinine levels in mice were increased in response to vancomycin administration and kidney histology showed an abnormality in functional units. The apoptotic cells were very visible in kidney structure in vancomycin treated group. These symptoms were however relieved in groups where treatment of S. marianum extract was given. mRNA expression of p53 , p21, and cyt-c also reduced in S. marianum treated groups of mice. S. marianum extract has protective effects against renal damage from vancomycin induced oxidative stress and relieves symptoms may be by downregulating apoptotic genes.

Kangaroo mother care: need of the day.

Each year approximately 20 million low birthweight babies are born globally. Prematurity is a leading cause of neonatal mortality in developing countries and results in 60%-80% of neonatal deaths. Neonatal mortality is the major contributor to under-5 mortality. According to Pakistan Demographic and Health Survey 2017-2018, neonatal mortality in Pakistan is 42 per 1000 live births and under-5 mortality is 74 per 1000 live births. One out of every 22 newborns dies in Pakistan, which is an alarming figure. Majority of these deaths are preventable. They can be prevented by well-trained midwives, safe delivery, early initiation of breast feeding within an hour after birth and skin-to-skin contact. Pakistan is among the top 10 countries with the highest number of preterm births and with limited resources to manage the burden. Kangaroo mother care (KMC) is a safe and economical alternative to provide preterm care in developing countries. In babies at gestational age less than 37 weeks or with neonatal weight less than 2.5 kg, skin-to-skin contact prevents hypothermia and infection. Neonatal mortality and morbidity can be reduced by providing preterm care through KMC. This case report is of a preterm baby who was delivered at 33 weeks of gestation with a weight of 1.3 kg and was saved by KMC in the paediatric department of Services Hospital in Lahore.
