RESUMEN
PROBLEM: Early-onset preeclampsia (EOPE) is a severe gestational hypertensive disorder with significant feto-maternal morbidity and mortality due to uteroplacental insufficiency. Circulating extracellular vesicles of placental origin (EV-P) are known to be involved in the pathophysiology of EOPE and might serve as an ideal reservoir for its specific biomarkers. Therefore, we aimed to characterize and perform comparative proteomics of circulating EV-P from healthy pregnant and EOPE women before delivery. METHOD OF STUDY: The EV-P from both groups were isolated using immunoaffinity and were characterized using transmission electron microscopy, dynamic light scattering, nanoparticle tracking analysis, and immunoblotting. Following IgG albumin depletion, the pooled proteins that were isolated from EV-P of both groups were subjected to quantitative TMT proteomics. RESULTS: Circulating term EV-P isolated from both groups revealed â¼150 nm spherical vesicles containing CD9 and CD63 along with placental PLAP and HLA-G proteins. Additionally, the concentration of EOPE-derived EV-P was significantly increased. A total of 208 proteins were identified, with 26 among them being differentially abundant in EV-P of EOPE women. This study linked the pathophysiology of EOPE to 19 known and seven novel proteins associated with innate immune responses such as complement and TLR signaling along with hemostasis and oxygen homeostasis. CONCLUSION: The theory suggesting circulating EVs of placental origin could mimic molecular information from the parent organ-"the placenta"-is strengthened by this study. The findings pave the way for possible discovery of novel prognostic and predictive biomarkers as well as provide insight into the mechanisms driving the pathogenesis of EOPE.

Monkeypox is a contagious viral disease that spreads between animals and people. The UK government guidance described the first case of 'Monkey Pox' in 1958, when it was found only in monkeys used for research purposes. Fortunately, for a third world fast developing country like India, monkeypox does not spread easily in the population but spread by close physical contact between people, and there is limited information available about the impact on pregnancy. The virus can enter the body through broken skin, the respiratory tract, or mucous membranes (the moist inner lining of cavities and some organs in the body). The signs and symptoms of monkeypox virus infection in people who are pregnant appear similar to those in nonpregnant people. The symptoms include fever, lymphadenopathy, lethargy, pharyngitis, headache, myalgias, and rash. Rash associated with monkeypox virus infection can be found in the anogenital area (most commonly reported location in this current outbreak), trunk, arms, legs, face, and the palms and soles. The diagnostic approach to a patient with suspected monkeypox virus infection is the same for pregnant and nonpregnant people. If a patient is present with signs and symptoms of monkeypox virus infection, diagnostic testing should be considered, especially if the person has risk factors for monkeypox virus infection. There are limited data on monkeypox infection during pregnancy. It is unknown whether pregnant people are more susceptible to monkeypox virus or whether infection is more severe in pregnancy. Monkeypox virus can be transmitted to the fetus during pregnancy or to the newborn by close contact during and after birth. Adverse pregnancy outcomes, including spontaneous pregnancy loss and stillbirth, have been reported in cases of confirmed monkeypox infection during pregnancy. Preterm delivery and neonatal monkeypox infection have also been reported. Monkeypox virus can be transmitted to the fetus during pregnancy or to the newborn by close contact during and after birth. Adverse pregnancy outcomes, including spontaneous pregnancy loss and stillbirth, have been reported in cases of confirmed monkeypox infection during pregnancy. Infection control practices for the care of patients who are pregnant with monkeypox infection are the same as those for patients who are not pregnant with monkeypox infection. This includes appropriate isolation of patients with monkeypox; training for health-care personnel on maternity and newborn care units on correct adherence to infection control practices and personal protective equipment (PPE) use and handling; and ensuring sufficient and appropriate PPE supplies are positioned at all points of care. Furthermore, visitors to pregnant or postpartum patients with monkeypox should be strictly limited to those essential for the patient's care and well-being, and should have no direct contact with the patient. Use of alternative mechanisms for patient and visitor interactions, such as video-call applications, should be encouraged for any additional support. CDC also recommends pregnant, postnatal, and breastfeeding women should be prioritized for medical treatment as there is a significant risk to the baby. They also identify these groups as eligible for treatment.
RESUMEN
BACKGROUND: Laparoscopic port entry is crucial and vital step in any laparoscopic surgery. As laparoscopy is widely used, complications related to it are also increasing which are not seen in conventional laparotomy. AIM: The present study was undertaken to compare the ease of primary trocar entry after pneumoperitoneum at 20 mmHg pressure and direct trocar entry without pneumoperitoneum. METHODS: Total 100 nulliparous patients who presented for elective gynaecologic laparoscopic surgery were enrolled for the study. In operating theatre, randomization of patients was done using a sealed envelope technique which divides patients into two equal groups and assigned as either low-pressure group or high-pressure group. Verres needle insertion and trocar entry was done by fellowship trainee in laparoscopy assisted by senior laparoscopy surgeon. RESULT: In high-pressure group we had trocar entry in first attempt in 80% of patient, second attempt in 20% where as in direct trocar entry group required first attempt in 88%, second attempt in 10% and third attempt in 2%. Time taken for trocar entry between two groups was significantly different requiring 4.42 ± 0.55 min for high pressure and 1.2 ± 0.28 min for direct trocar entry. CONCLUSION: The study concluded that high-pressure trocar entry requires more time; require less attempts, easier and surgeon will be more comfortable in repeating the same technique than direct trocar entry.
