Efficacy of Uterovaginal Packing Versus Uterine Balloon Tamponade to Control Postpartum Hemorrhage Due to Uterine Atony

OBJECTIVES To determine and compare the efficacy of Uterovaginal packing versus uterine balloon tamponade to control postpartum haemorrhage due to uterine atony unresponsive to medical treatment. METHODOLOGY This comparative prospective cross-sectional study was conducted in Hayatabad Medical Complex, OBG department. A total of 140 patients were categorised into two groups, group A underwent Uterovaginal packing and group B underwent uterine balloon tamponade. All women of 18 to 40 years with a history of delivery after 28 weeks of gestation, who developed primary postpartum haemorrhage due to uterine atony, unresponsive to medical treatment were included in the study. Women with a history of delivery before 28 weeks of gestation, secondary postpartum haemorrhage, genital tract trauma, retained placental tissue and membranes, placenta previa, morbidly adherent placenta, febrile illness and uterine structural lesion were excluded from the study. Efficacy was labelled if there was no ongoing blood loss after the procedure with concomitant hemodynamic stability. All information was recorded in a predesigned proforma, and data were analysed using SPSS version 22.RESULTS Our study included 140 women; 113 had a normal vaginal delivery, and 27 underwent cesarean section. Among cases with normal vaginal delivery, 45 women had Uterovaginal packing, and 68 had uterine balloon tamponade, while among cases of cesarean sections, 25 women had uterovaginal packing and 2 had uterine balloon tamponade. The efficacy of Uterovaginal packing was 90%, and that of uterine balloon tamponade was 87.1%, with no significant difference statistically (p- 0.51). Overall efficacy of both procedures was 88.6%.CONCLUSION All orthodontic and non-orthodontic treatment group participants required oral hygiene instructions and had periodontal treatment needs (TN1). The patients requiring scaling and prophylaxis and Oral hygiene instructions (TN 2) were more in the orthodontic treatment group than the non-orthodontic treatment group. A higher percentage of patients requiring complex treatment (deep scaling, root planning and complex surgical procedures), scaling and prophylaxis and Oral hygiene instructions (TN3) belonged to the non-orthodontic treatment group

Synergistic biomedical potential and molecular docking analyses of coumarin–triazole hybrids as tyrosinase inhibitors: design, synthesis, in vitro profiling, and in silico studies

The tyrosinase enzyme has a vital role in the browning of vegetables and fruits and the biosynthesis of melanin. In this work, we synthesized a diverse library of coumarin–triazole hybrids, and these compounds were characterized by using suitable analytical techniques. Our research work extends beyond the synthetic effort to explore the therapeutic potential of these compounds. We put the synthesized compounds through meticulous in vitro screening against the tyrosinase enzyme, and these coumarin derivatives evinced good IC50 values in the range of 0.339 ± 0.25 µM to 14.06 ± 0.92 µM. In the library of synthesized compounds, six compounds were found to be more potent than standard ascorbic acid (IC50 = 11.5 ± 1.00), and among them, 17e and 17f, being the most active, exhibited remarkable anti-tyrosinase potential, with IC50 values of 0.339 ± 0.25 μM and 3.148 ± 0.23 μM, respectively. Furthermore, an in silico modeling study was carried out to determine the key interactions of these compounds with the tyrosinase protein (PDB ID: 2Y9X) and thus to authenticate our experimental findings. The quantitative SAR studies exhibited a good correlation between the synthesized derivatives of coumarin and their anti-tyrosinase activity. The docking studies verified the experimental results, and ligand 17e showed good interaction with the core residues of tyrosinase. This study not only expands the field of coumarin–triazole hybrid synthesis but also provides valuable insights for the development of novel tyrosinase inhibitors

احسان دانش: شاعرِ مزدور

Ehsan Danish has his own distinct identity in the literature of twentieth century folk and local poetry. That is why he is called the poet of labour. Ehsan Danish in his poems has fully reflected the lower class, especially the problems of the workers and their suffering and pains. A large part of his poetic themes are in opposition to the feudal system. But his poetic temperament differs from the point of view of the progressive movement. Ehsan Danish’s protests and uprisings against capitalistic culture is the topic of this article

Basics of faculty-to-faculty mentoring: A process to identify support and challenges.

Faculty mentoring is relatively new in health sciences literature. Faculty mentors are considered to have multiple roles including being a supervisor, teacher, or a coach. Little or no attention to formal mentoring of faculty allows faculty to seek informal mentoring, creating a risk of unexpected outcome. There is dearth of literature with respect to formal mentoring programs from the subcontinent. Although, informal faculty mentoring has been in place but there is no standard faculty mentorship model to be followed at Aga Khan University Medical College (AKU-MC). An observational study was conducted in September 2021 at AKU MC with convenient sampling to share the perceptions of the AKU-MC faculty mentors in a faculty mentorship workshop so that further advanced level faculty development workshops could be planned in this area. Twenty-two faculty mentors participated to share their perspectives on the responsibilities of faculty mentor, faculty mentee and the institution to see faculty grow and to have a sustainable mentorship programme. Challenges faced by the faculty mentors during the process of mentorship were also discussed. Majority of the participants emphasized on the role of the faculty mentor to be supportive, guiding, reflective and formative (respond to the emotional needs, encourage, effective communication, know own limitations, observe, provide feedback). Faculty mentor role modeling, ability to maintain confidentiality, creating and maintaining mentor-mentee relationship, availability of framework of formal mentoring in an academic institution and opportunities within the academic setting to learn mentorship were the main challenges of being a faculty mentor. The process provided valuable training and education to the faculty for the development and strengthening of formal mentoring program. Faculty recommended that institutions should provide the opportunity for development of junior faculty mentors by organizing capacity building activities

Development of novel polymer haemoglobin based particles as an antioxidant, antibacterial and an oxygen carrier agents

Abstract This innovative work aims to develop highly biocompatible and degradable nanoparticles by encapsulating haemoglobin (Hb) within poly-ε-caprolactone for novel biomedical applications. We used a modified double emulsion solvent evaporation method to fabricate the particles. A Scanning electron microscope (SEM) characterized them for surface morphology. Fourier Transform Infrared Spectroscopy (FTIR) and Ultraviolet–visible spectroscopies (UV–visible) elucidated preserved chemical and biological structure of encapsulated haemoglobin. The airproof equilibrium apparatus obtained the oxygen-carrying capacity and P50 values. The DPPH assay assessed free radical scavenging potential. The antibacterial properties were observed using four different bacterial strains by disk diffusion method. The MTT assay investigates the cytotoxic effects on mouse fibroblast cultured cell lines (L-929). The MTT assay showed that nanoparticles have no toxicity over large concentrations. The well-preserved structure of Hb within particles, no toxicity, high oxygen affinity, P50 value, and IC50 values open the area of new research, which may be used as artificial oxygen carriers, antioxidant, and antibacterial agents, potential therapeutic agents as well as drug carrier particles to treat the cancerous cells. The novelty of this work is the antioxidant and antibacterial properties of developed nanoparticles are not been reported yet. Results showed that the prepared particles have strong antioxidant and antibacterial potential
