RESUMEN

OBJECTIVE: To compare high-para and low-para women with respect to haematological findings, determinants, and consequences secondary to anaemia. STUDY DESIGN: Descriptive cohort study. Place and Duration of the Study: Maternity and Child Hospital, Hail, Saudi Arabia and Specialist Care Hospital (private), Islamabad, Pakistan, from April 2022 to April 2023. METHODOLOGY: The study population comprised of pregnant women in the last trimester, with the exception of those women who had more than one fetus and history of haematological disease. Purposive non-probability sampling technique was adopted. Hospital data were retrieved retrospectively for the past obstetrical, contraception usage, and supplement history. Blood parameters, type of delivery, and maternofetal complications were noted down. For qualitative-variable and quantitative-variable comparisons, Chi-square test and t-test were applied, respectively. Significance level was kept at p ≤0.05. RESULTS: The frequency of severe anaemia in high-para was 52%. High parity and anaemia had a significant dose-response relationship (p <0.05). There was a significant difference (p <0.05) in blood parameters between high-para and low-para groups. Main determinants identified for anaemia were lack of intake of iron-rich food (36%) followed by inadequate intake of oral iron (25%). Preterm birth (68%) and post-partum haemorrhage (96%) were significantly associated (p <0.05) with high parity. There was a significantly high proportion (83%) of high-para women with more than 3 cesarean deliveries and admissions in ICU. CONCLUSION: High parity and anaemia had a significant dose-response relationship. High parity was the main determinant of maternal and fetal admissions in ICU. KEY WORDS: Parity, Comparison, Maternal anaemia, Haematological findings, Diet, Contraception, Cost-effective.

RESUMEN

Multidisciplinary research efforts on potential COVID-19 vaccine and therapeutic candidates have increased since the pandemic outbreak of SARS-CoV-2 in 2019. This search has become imperative due to the increasing emergences and limited widely available medicines. The presence of bioactive anti-SARS-CoV-2 molecules was examined from various plant sources. Among them is a group of proteins called lectins that can bind carbohydrate moieties. In this article, we present ten novel, chitin-specific Hevein-like lectins that were derived from Selaginella moellendorffii v1.0's genome. The capacity of these lectin homologs to bind with the spike protein of SARS-CoV-2 was examined. Using the HDOCK server, 3D-modeled Hevein-domains were docked to the spike protein's receptor binding domain (RBD). The Smo446851, Smo125663, and Smo99732 interacted with Asn343-located complex N-glycan and RBD residues, respectively, with binding free energies of -17.5, -13.0, and -26.5 Kcal/mol. The molecular dynamics simulation using Desmond and the normal-state analyses via torsional coordinate association for the Smo99732-RBD complex using iMODS is characterized by overall higher stability and minimum deformity than the other lectin complexes. The three lectins interacting with carbohydrates were docked against five individual mutations that frequently occur in major SARS-CoV-2 variants. These were in the spike protein's receptor-binding motif (RBM), while Smo125663 and Smo99732 only interacted with the spike glycoprotein in a protein-protein manner. The precursors for the Hevein-like homologs underwent additional characterization, and their expressional profile in different tissues was studied. These in silico findings offered potential lectin candidates targeting key N-glycan sites crucial to the virus's virulence and infection.

RESUMEN

The lethal pathogenic severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has caused the COVID-19 pandemic, posing serious risks to people. The clove-like spike (S) protein that distinguishes coronaviruses from other viruses is important for viral pathogenicity, evolution, and transmission. The investigation of the unique structural mutations of the SARS-CoV-2 spike protein among 34 Asian countries, as well as the resulting phylogenetic relationship, provided critical information in understanding the pathogenesis. This can be utilized for the discovery of possible treatments and vaccine development. The current study analyzed and depicted phylogenetic and evolutionary models useful for understanding SARS-CoV-2 human-human transmission dynamics in Asian regions with shared land borders. Further, integrated bioinformatics analysis was performed to predict the pathogenic potential and stability of 53 mutational positions among 34 coronavirus strains. Mutations at positions N969K, D614G and S884F have deleterious effects on protein function. These findings are crucial because the Asian mutations could potentially provide a vaccine candidate with co-protection against all SARS-CoV-2 strains. This region is vulnerable because of the high population density and the volume of domestic and international travel for business and tourism. These discoveries would also aid in the development of plans for governments and the general populace to implement all required biocontainment protocols common to all countries.

RESUMEN

In the context of the global increase in the rate of cesarean deliveries, with an associated higher morbidity and mortality, this study aimed to investigate the role of maternal age and parity in the cesarean section rate among women in the Hail Region of Saudi Arabia. This retrospective cohort study used data collected from the labor ward of the Maternity and Child Health Hospital, Hail, over a period of 8 months, forming a cohort of 500 women. Women were categorized into four different parity classes. The results revealed that there was no significant relationship between cesarean deliveries and maternal age (p-value, 0.07). There was no significant difference in the mode of delivery between the study's parity cohort group. A significant increase in cesarean deliveries was noticed among obese women with a BMI between 35-39.9 (52.14%). This increase was even greater among those with a BMI above 40 (63.83%). Fetal distress, malpresentation and abruptio placenta were the most significant indications for CS among all age groups (p-value 0.000, 0.021, and 0.048, respectively). Conclusions: The number of cesarean deliveries has no association with parity or age. However, there was a statistically significant association with BMI, a perineal tear after previous vaginal delivery, and a history of diabetes mellitus and gestational diabetes. The most reported reasons for CS were fetal distress, malpresentation, and abruptio placenta among all age groups.

RESUMEN

The burden of allergic illnesses is continuously rising, and patient diagnosis is a significant problem because of how intricately hereditary and environmental variables interact. The past three to four decades have seen an outbreak of allergies in high-income countries. According to reports on the illness, asthma affects around 300 million individuals worldwide. Identifying clinically important allergens for the accurate classification of IgE-mediated allergy respiratory disease diagnosis would be beneficial for implementing standardized allergen-associated therapy. Therefore, the current study includes an in silico analysis to identify potential IgE-mediated allergens in date palms and cockroaches. Such an immunoinformatic approach aids the prioritization of allergens with probable involvement in IgE-mediated allergic respiratory diseases. Immunoglobulin E (IgE) was used for molecular dynamic simulations, antigen-antibody docking analyses, epitope identifications, and characterizations. The potential of these allergens (Per a7, Per a 1.0102, and Bla g 1.0101) in IgE-mediated allergic respiratory diseases was explored through the evaluation of physicochemical characteristics, interaction observations, docking, and molecular dynamics simulations for drug and vaccine development.

RESUMEN

High parity is associated with the risk of fetomaternal complications such as gestational diabetes mellitus, hypertensive disorders, maternal anemia, preterm labor, miscarriage, postpartum hemorrhage, and perinatal and preterm mortality. The objective of the study was to compare fetomaternal complications in women of high parity with women of low parity. This involved a cohort study on a sample size of 500 women who had singleton births. Data were collected from the Maternity and Child Hospital, Ha'il, Kingdom of Saudi Arabia. Participants were classified into two groups according to parity, i.e., women of low parity and women of high parity. Socio-demographic data and pregnancy complications, such as gestational diabetes, hypertension, preeclampsia, intrauterine growth restriction, etc., were retrieved from participants' files. Participants were followed in the postnatal ward until their discharge. The results revealed that women of high parity mostly (49%) were married before 20 years of age, less educated, obese, and were of un-booked cases. Premature babies and fetal mortality are significantly high (0.000) in this group. There is a significant difference between the two groups with respect to maternal anemia, gestational diabetes mellitus, joint pain, perineal tear, miscarriage, postpartum hemorrhage, preeclampsia, vaginal tear, and cesarean section. Determinants responsible for high parity should be identified via evidence-based medicine. Public health education programs targeting couples, weight control, nutrition, and contraception would be a cost-effective strategy for reducing the risk of possible fetomaternal complications.

RESUMEN

The devastating COVID-19 pandemic has created several gaps in the management of viral infections, leaving biocontainment and supportive measures as the only resorts for control. As such, there has been a dramatic increase in the use of dietary supplementations and herbal medicine for COVID-19. However, serious concerns regarding the efficacy, safety, and recommended doses of these medicines have been raised. In this study, we aimed to assess the population knowledge about alternative medicine administration for COVID-19 and the associated factors. Using a self-administered cross-sectional survey, we analyzed a total of 2042 valid responses. Most of the included participants were females (69.7%), with an overall mean age of 20.8 ± 11.8 years. Most respondents (62.8%) obtained their knowledge from social media while only 16.6% received knowledge from the health care workers. Half of the participants (50.6%) correctly identified all COVID-19 symptoms, where fever (18.5%) and loss of smell and taste (17.1%) were the most frequent answers. On the use of traditional medicines and supplements for COVID-19, 57.8% did not answer, 23.7% admitted regular use, and 18.5% used sometimes. Family members or friends suggested the use of traditional medicines and dietary supplements to 28.0% of the participants while only 14.7% were advised by a nutritionist, physician, pharmacist, nurse, or a health worker. Moreover, seniors and illiterate portions of society had lower knowledge scores and increased utilization of alternative medicine. Marital status, income, and previous COVID-19 were all significant predictors of the awareness and knowledge score. Thus, this study has identified overuse of unregulated medicinal products in the region, which potentially aggravates COVID-19 or other underlying risks of the disease, making clinical management challenging, particularly in geriatrics and women's health. Regulation of medicinal products and establishment of educational campaigns about the disease have become imperative.
