Cardiovascular Complications in Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is an auto-immune disease of a relapsing-remitting nature that can cause multiorgan damage depending on several factors, mainly the disease activity. Young age women are the most likely to be affected by the disease and the female-to-male prevalence ratio is approximately 1:10. As the number of SLE patients has been increasing in the last few decades, the annual number of deaths due to the disease and its complications has increased as well, and one of the most important systems to which high mortality is attributed is the cardiovascular system, leading to premature atherosclerosis and other events such as endocarditis and valve disease.

The Association of Epstein-Barr Virus With Cancer.

Epstein-Barr virus (EBV) is classified as a herpesvirus and is known for being one of the few viruses that can lead to the development of cancer. This study has gathered several studies to provide evidence as to this association as well as some of the mechanisms specific to EBV that allow this to happen. The development of EBV into cancer as well as the proteins involved in this oncogenesis play a crucial role in understanding this problem as well as creating a solution for mitigating this disease process in the future.

Diagnostic Delays and Psychosocial Outcomes of Childhood-Onset Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder that manifests in affected individuals with a variety of clinical features and involves multiple organs. Despite recent advances over the past decades, higher morbidity and mortality have been reported by studies in patients with childhood-onset systemic lupus erythematosus (cSLE) compared to patients with adult-onset. The interplay of several factors can cause diagnostic delays resulting in worse disease activity, multiple organ damage, increased risk of hospitalization, and management with aggressive treatment.

The Effect of Sepsis on Myocardial Function: A Review of Pathophysiology, Diagnostic Criteria, and Treatment.

Sepsis remains a worldwide challenge for physicians with many patients admitted to ICUs with septic shock. Septic shock management involves targeted treatment to control infections, reduce end-organ damage, and reverse the injury. Sepsis-induced myocardial dysfunction or septic cardiomyopathy remains an avenue to be explored with regard to underlying pathophysiology and definite treatment guidelines.

Maternal and Neonatal Outcomes of Adolescent Pregnancy: A Narrative Review.

Adolescent pregnancy is the pregnancy of girls aged 10-19 years, leading to many maternal and neonatal adverse effects. These pregnancies have been a global concern for many decades and yet are still prevailing. This article has reviewed the significant determinants of adolescent pregnancy and various maternal adverse effects, including preeclampsia, preterm premature rupture of the membrane (PPROM), maternal anemia, sexually transmitted diseases, postpartum depression, and maternal deaths, and adverse neonatal outcomes, including low birth weight (LBW), prematurity, stillbirths, early neonatal demise, and low Apgar score.

Digital technologies in management of chronic pain - a systematic review.

Objective: To determine the effectiveness of digital health technologies in the management of chronic pain.

Methods: The systematic review comprised search for randomised controlled trials and controlled clinical trials involving patients with chronic pain published between 2010 and 2020. The search was conducted on PubMed, Google Scholar, MEDLINE, National Centre for Biotechnology Information, and National Library of Medicine databases.

Ruptured Rudimentary Horn Pregnancy Revealed on Emergency Laparotomy: A Case of Primigravida Presenting in a Developing Country.

Developmental defects in the Mullerian ducts can result in several uterine anomalies including a unicornuate uterus with a rudimentary horn. Pregnancy in a rudimentary horn is extremely rare occurring in 1:76,000-1:160,000 pregnancies. We present a case of an 18-year-old primigravida with a ruptured rudimentary horn pregnancy (RHP) presenting as acute abdomen at 17 weeks of gestation.

Differences in symptoms and presentation delay times in myocardial infarction patients with and without diabetes: A cross-sectional study in Pakistan.

Objective: A short pre-hospital delay, from the onset of symptoms to rapid initiation of reperfusion therapy, is a crucial factor in determining prognosis of myocardial infarction (MI). The purpose of this study was to evaluate symptoms and presentation delay times in MI patients with and without diabetes.

Methods: This cross-sectional study was conducted in 3 tertiary care hospitals of Pakistan over a period of 6 months.

Hospital-based study of epithelial malignancies of endometrial cancer frequency in lahore, pakistan, and common diagnostic pitfalls.

The current study was conducted to see the frequency of epithelial malignancies of endometrium with focus on the common diagnostic pitfalls and identify morphological and immunohistochemical markers helpful in the differential diagnosis between different subtypes. It is a retrospective descriptive study carried out on 52 specimens of endometrial tumors received in Fatima Memorial Hospital, Lahore, Pakistan, during three years (2010-2012). Patients were divided into 5 age groups: <40, 41-50, 51-60, 61-70, and >70 yrs.

Gβγ-independent recruitment of G-protein coupled receptor kinase 2 drives tumor necrosis factor α-induced cardiac β-adrenergic receptor dysfunction.

Background: Proinflammatory cytokine tumor necrosis factor-α (TNFα) induces β-adrenergic receptor (βAR) desensitization, but mechanisms proximal to the receptor in contributing to cardiac dysfunction are not known.

Methods And Results: Two different proinflammatory transgenic mouse models with cardiac overexpression of myotrophin (a prohypertrophic molecule) or TNFα showed that TNFα alone is sufficient to mediate βAR desensitization as measured by cardiac adenylyl cyclase activity. M-mode echocardiography in these mouse models showed cardiac dysfunction paralleling βAR desensitization independent of sympathetic overdrive.

Inhibition of protein phosphatase 2A activity by PI3Kγ regulates β-adrenergic receptor function.

Phosphoinositide 3-kinase γ (PI3Kγ) is activated by G protein-coupled receptors (GPCRs). We show here that PI3Kγ inhibits protein phosphatase 2A (PP2A) at the β-adrenergic receptor (βAR, a GPCR) complex altering G protein coupling. PI3Kγ inhibition results in significant increase of βAR-associated phosphatase activity leading to receptor dephosphorylation and resensitization preserving cardiac function.

Synthesis of monofunctional curcumin derivatives, clicked curcumin dimer, and a PAMAM dendrimer curcumin conjugate for therapeutic applications.

Curcumin, the primary active ingredient in the spice turmeric, was converted to reactive monofunctional derivatives (carboxylic acid/azide/alkyne). The derivatives were employed to produce a 3 + 2 azide-alkyne "clicked" curcumin dimer and a poly(amidoamine) (PAMAM) dendrimer-curcumin conjugate. The monofunctional curcumin derivatives retain biological activity and are efficient for labeling and dissolving amyloid fibrils.
