Background: Premenstrual dysphoric disorder (PMDD) is a condition that affects nearly 3-9% of the women in the reproductive age during the luteal phase of each menstrual cycle characterized by symptoms varying in severity and affecting the quality of life. Earlier research studies conducted have reported independent relationships between PvuII-ESR1-polymorphism and psychological traits in PMDD and risk for cognitive, behavioral, and affective symptoms. However, as the studies are few in number and the results are not consistent, there is a need for our study to link between the PvuII-ESR1gene and PMDD.

Article Synopsis
  • Uterine fibroids are non-cancerous growths in women's reproductive muscles, affecting over 75% of women and causing issues like pain and heavy periods.
  • Researchers found that a protein called PRICKLE1 is lower in these fibroids, and its loss is linked to changes in another protein, REST, which can lead to tumor development.
  • Estrogen, a hormone, seems to lower PRICKLE1 and REST levels; understanding this connection could help in finding new ways to treat fibroids.

Multidrug-resistant sepsis (MDR) is a pressing concern in intensive care unit (ICU) settings, specifically among geriatric patients who experience age-related immune system changes and comorbidities. The aim of this review is to explore the clinical impact of MDR sepsis in geriatric ICU patients and shed light on healthcare challenges associated with its management. We conducted a comprehensive literature search using the National Center for Biotechnology Information (NCBI) and Google Scholar search engines.

Article Synopsis
  • RASopathies are malformation syndromes linked to severe cases of nonimmune hydrops fetalis (NIHF), but their contribution to NIHF is not well documented, and pathogenic variants can arise de novo or be inherited.
  • A systematic review of prenatal exome sequencing (ES) studies identified 36 relevant studies, revealing that RASopathies were diagnosed in 9% of all NIHF cases and at a higher rate of 23% among genetically diagnosed cases.
  • Of the 46 identified NIHF cases with RASopathy variants, 28% were inherited, with the majority (63%) classified as isolated cases without other anomalies detected prenatally.

  • The study aimed to assess the significance of PIEZO1 gene variants found through prenatal exome sequencing in cases of non-immune hydrops fetalis (NIHF).
  • A systematic review of studies from 2000 to 2022 identified 36 relevant articles, leading to an analysis of 22 pregnancies with 35 unique PIEZO1 variants.
  • Findings indicated that PIEZO1 variants were diagnosed in 10% of NIHF cases, establishing it as the most frequently identified single gene involved in this condition, with variants categorized as either dominant or recessive.

Research on the compatibility of time domain indices, frequency domain measurements of heart rate variability obtained from electrocardiogram (ECG) waveforms, and pulse wave signal (pulse rate variability; PRV) features is ongoing. The promising marker of cardiac autonomic function is heart rate variability. Recent research has looked at various other physiological markers, leading to the emergence of pulse rate variability.

Online assessments are needed during the prevailing pandemic situation to continue educational activities while ensuring safety. After conducting the online practical assessment (OPrA) in Biochemistry, we analyzed the students' responses. The blueprint of the OPrA was prepared by the faculty, referring to the various levels and domains of Bloom's taxonomy.

Article Synopsis
  • - Non-immune hydrops fetalis (NIHF) can have various genetic causes that can be identified using exome sequencing (ES), which enhances traditional prenatal diagnostic methods.
  • - A systematic review of 31 studies involving 445 NIHF cases found a 37% diagnostic rate, indicating that ES is particularly effective in consanguineous cases compared to non-consanguineous ones.
  • - The genetic variants identified included several disease categories, primarily RASopathies (24%) and neuromuscular disorders (21%), with a majority of cases showing recessive inheritance patterns (55%).

Background And Purpose: Rescue stenting is used as a bailout technique during mechanical thrombectomy for stroke. We performed a retrospective study analyzing outcomes of patients that received a stent as a bailout measure and compared results to a control group.

Methods: We identified all patients who underwent a mechanical thrombectomy for a large vessel occlusion between January 2010 and October 2019.

Aims: Inflammatory stage in prediabetes is associated with increase in level of adipokines and pro-inflammatory cytokines. Physical activity promotion considered as a first-line therapeutic strategy to treat prediabetes. We have conducted the systematic review and meta-analysis to strengthen the evidence on the impact of physical activity promotion on inflammatory markers in prediabetes.

  • Intra-arterial chemotherapy (IAC) has significantly improved treatment outcomes for retinoblastoma, even in infants weighing 10 kg or less.
  • A study including 207 tumors showed that smaller patients had a higher rate of complete tumor regression (82.6% vs. 60.9%) and less cumulative radiation exposure, while periprocedural complications remained low and similar between weight groups.
  • IAC is deemed safe and effective for treating retinoblastoma in infants, despite a higher frequency of aborted procedures.

  • Intra-arterial chemotherapy (IAC) for retinoblastoma has significantly improved survival rates, exceeding 70%.
  • This study examined the effectiveness of IAC through different methods when standard ophthalmic artery catheterization (OAC) wasn't viable, including external carotid artery catheterization and balloon-assisted delivery.
  • Results showed a high overall success rate of 97% across 658 IAC procedures, indicating that alternative techniques for administering chemotherapy are just as effective as the traditional OAC method.

Antiepileptic Drugs (AEDs) are commonly associated with haematological disorders, including anaemia, thrombocytopenia, neutropenia and even bone marrow failure. Fatal disorders like aplastic anaemia are uncommon. On exploring through the literature, older AEDs are more associated with haematological alterations than newer AEDs, and careful monitoring is warranted especially with phenytoin, carbamazepine and valproate.
