Classification of caesarean section based on Robson ten group classification system in our hospital

Background: Recent data indicate that one in five women undergo caesarean section (CS). In the last decade, there has been a dramatic increase in the caesarean section rate worldwide, which now exceeds 30% in some regions. Thus, the increasing rate of caesarean section became a matter of international public health concern. Our study aimed to classify the CS-based on Robson ten group classification system (RTGCS) criteria which will subsequently enable us to standardise the indication of CS and establish protocols to reduce the number of CS in our set up.Method: A retrospective study was conducted in ESI Hospital, New Delhi wherein Robson TGCS was used to classify CS for 15 months (January 2019 to April 2020).Results: Overall CS rate in our hospital over the specified period was 34.5%. All women with one or more previous cesareans (group V) had the maximum number of cesareans, 37%, followed by nulliparous, single, cephalic, term pregnancy (induced) i.e group II, 22.1% and nulliparous women more than 37 weeks in spontaneous labour (group I), 9.5%.Conclusions: RTGCS is easy to comprehend and reproduce. All deliveries and cesareans should be universally categorized by the Robsons TGCS. An attempt should be made to evaluate the group contributing most to the CS rate and interventions should be made accordingly

A study of the formation constants of ternary and quaternary complexes of some bivalent transition metals

The formation of hetero-ligand 1:1:1, M(II)-Opda-Sal/Gly ternary and 1:1:1:1, M(II)-Opda-Sal-Gly quaternary complexes, where M(II) = Ni, Cu, Zn and Cd; Opda = o‑phenylenediamine, Sal = salicylic acid, Gly = glycine, was studied pH-metrically in aqueous medium. The formation constants for the resulting ternary and quaternary complexes were evaluated at a constant ionic strength, μ = 0.20 mol dm-3 and temperature, 30±0.1 °C. The order of the formation constants in terms of the metal ion for both type of complexes was found to be Cu(II) > Ni(II) > Zn(II) > Cd(II). This order was explained based on the increasing number of fused rings, the coordination number of the metal ions, the Irving – William order and the stability of various species. The expected species formed in solution were pruned with the Fortran IV program SPEPLOT and the stability of the ternary and quaternary complexes is explained

Ruptured cornual ectopic pregnancy: a case report

A cornual gestation is one of the most hazardous and life-threatening type of ectopic pregnancy with a mortality rate of 2-5 times higher than other ectopic pregnancies. Because of the myometrium stretch ability, they usually present late around 7-12 weeks of gestation. Thus, the diagnosis and treatment of such cases become challenging. In the case of ruptured cornual ectopic pregnancy, the patient usually presents with hemodynamic instability. Presenting a case report of a 28-year-old female who presented to the labour room of ESI hospital, Okhla, New Delhi at 12 weeks of pregnancy in a state of shock. A provisional diagnosis of ruptured cornual ectopic was made based on clinical examination and ultrasound report. Resuscitation followed by emergency laparotomy done as a life-saving procedure for the patient. Ruptured cornual ectopic needs urgent intervention and multidisciplinary approach. However, with the advancement and expertise in the field of radiology and early diagnosis can be made which can contribute towards more conservative management of such cases

Comparing difference in mean total protein, albumin and globulin based on severity of rhesus isoimmunization: a prospective study

Background: Maternal RBC alloimmunization results from exposure and response to a foreign RBC antigen. Transplacental fetal to maternal hemorrhage is the most common cause of alloimmunization. Rh incompatibility can lead to either fetuses with hydropic features or non-hydropic. The precise mechanism leading to the development of hydrops is uncertain. Biochemical markers have the potential to be used to assess the severity of problem. But of the mechanisms proposed none have been able to totally explain the phenomenon or predict the prognosis. Objective of this study wads to compare the difference in mean total protein, albumin and globulin bases on severity of isoimmunization and comparing it with normal controls.Methods: A Total of 40 pregnant patients were enrolled which included 10 hydropic fetuses of Rh isoimmunised mothers, 10 non hydropic fetuses of Rh isoimmunized mothers. Control group included 18 Rh positive women without any fetal complication and 2 fetuses in women undergoing cordocentesis. Blood sampling was done at time of intrauterine transfusion and sent for estimation of total proteins, albumin, globulin in fetal blood. Pregnancies were followed up till delivery and fetal outcome noted.Results: Mean total protein, albumin and globulin between hydropic, non hydropic group and control group (3.25, 2.17 and 1.18 g/dl) in hydropic, (4.14, 2.70 and 1.44 g/dl) in non hydropic and (4.42, 2.95 and 1.47 g/dl) in control group respectively. Mean total protein, albumin and globulin between mild hydropic (3.43, 2.30 and 2.10 g/dl) and severe hydropic group (2.59, 1.6 and 1.3 g/dl) respectively.Conclusions: There was significantly lower levels of serum total proteins, albumin and globulin in hydropic fetuses as compared to non hydropic fetuses. Thus, hypoproteinemia can be considered a strong marker for development of hydrops in Rh isoimmunized fetuses

An hitherto case of so-called extinct disease: Scurvy with review of the literature

oai:ojs.pkp.sfu.ca:article/22Scurvy which is known to be an extinct entity but still specks of this disease still persists in various parts of the world which goes with the famous saying that says “history often repeats.” Scurvy is sometimes referred to as Barlow’s disease, named after Sir Thomas Barlow, a British physician who described it. Scurvy is basically a disease that is known to occur because of inadequate supply of vitamin C to the body. To diagnose this disease without undergoing expensive investigations, history taking has been proven to be a powerful tool.We present a case of 2-year-old patient visiting our department with bleeding gums, joint pain and weakness. Clinical data along with a significant improvement after administering vitamin C supplement confirms the diagnosis

Assessment of the customized birth weight formula in a low risk Indian population

Background: Birth weight is probably the single most important factor that affects neonatal mortality, infant and childhood morbidity in both developed and developing countries. Objective of the study was to formulate a model for prediction of fetal weight at term based on individualized fetal growth parameters.Methods: 131 participant low risk gravidas were enrolled into the study. The participants underwent an ultrasound 7 days prior to delivery. All fetal variables of growth of a random 100 participants were incorporated in an equation derived using multiple regressions to predict birth weight at term. The new equation was then prospectively applied to another 31 pregnant women for validation. The diagnostic performance of the new regression formula was then compared to the Hadlock formula.Results: The customised birth weight formula predicted a higher accuracy with MPE±SD of 0.790±9. compared to the Hadlock formula with MPE±SD - 4.42±8.73. The new formula also explained a greater variance in birth weight of 56% compared to the Hadlock formula of 49%.Conclusions: The new model based on individualized fetal growth parameters recognizes the capacity to modulate an accurate final birth weight, thus emphasizing the need for customized population specific birth weight formulas

Optimization and effects of physico-chemical parameters on synthesis of Chitosan Nanoparticles by Ionic Gelation Technique

Background. Biopolymers are used as vehicles for the carrying drugs to their site of action. These polymers are less toxic and can even protect the drug entity from degradation in physiological conditions of the body. Large number of techniques are employed to prepare the nanoformulation of these polymers but ionic gelation is of great interest because no harsh and incompatible chemicals are used during the process. Chitosan nanoparticles are good drug carriers because of their good biocompatibility and biodegradability. As a new drug delivery system they have attracted attention due to their applications in loading protein, drugs etc.  In the present research ionic gelation technique have been optimized for the preparation of chitosan nanoparticles. Various physico-chemical parameters of Nanoparticles such as size, Zeta potential and poly dispersity index were evaluated under different process parameters. Result: In current study ionic gelation technique had been optimized for the preparation of chitosan nanoparticles. We have evaluated the effect of various physico-chemical parameters such as type of polyanion, Sonication, surfactant etc and their effect on size and zeta potential of nanoparticles had been studied. Conclusion: A novel Nanoparticle system composed of low molecular weight chitosan was successfully prepared in the present study by simple ionic-gelation techniques under aqueous-based conditions. It was observed that there was considerable effect of various physico- chemical parameters on size, zeta potential and polydispersity index of Nanoparticles prepared. Results shows that the size of Nanoparticles decreases with the increase in concentration of  Chitosan. Polyvinyl alcohol was found to be the best surfactant because it was very effective in decreasing the surface tension without increasing viscosity. Intermittent sonication during the process decreases the size of Nanoparticles considerably.Controled use of polyanions under different conditions can develop  negatively charged Nanoparticles that can be used for delivery of positively charded drugs and therapeutic molecules

Mutational characterization of Omicron SARS-CoV-2 lineages circulating in Chhattisgarh, a central state of India

IntroductionThe emergence of the Omicron SARS-CoV-2 variant from various states of India in early 2022 has caused fear of its rapid spread. The lack of such reports from Chhattisgarh (CG), a central state in India, has prompted us to identify the Omicron circulating lineages and their mutational dynamics.Materials and methodsWhole-genome sequencing (WGS) of SARS-CoV-2 was performed in 108 SARS-CoV-2 positive combined samples of nasopharyngeal and oropharyngeal swabs obtained from an equal number of patients.ResultsAll 108 SARS-CoV-2 sequences belonged to Omicron of clade 21L (84%), 22B (11%), and 22D (5%). BA.2 and its sub-lineages were predominantly found in 93.5% of patients, BA.5.2 and its sub-lineage BA.5.2.1 in 4.6% of patients, and B.1.1.529 in 2% of patients. Various BA.2 sub-lineages identified were BA.2 (38%), BA.2.38 (32%), BA.2.75 (9.25%), BA.2.56, BA.2.76, and BA.5.2.1 (5% each), BA.2.74 (4.6%), BA.5.2.1 (3.7%), BA.2.43 and B.1.1.529 (1.8% each), and BA.5.2 (0.9%). Maximum mutations were noticed in the spike (46), followed by the nucleocapsid (5), membrane (3), and envelope (2) genes. Mutations detected in the spike gene of different Omicron variants were BA.1.1.529 (32), BA.2 (44), BA.2.38 (37), BA.2.43 (38), BA.2.56 (30), BA.2.74 (31), BA.2.75 (37), BA.2.76 (32), BA.5.2, and BA.5.2.1 (38 similar mutations). The spike gene showed the signature mutations of T19I and V213G in the N-terminal domain (NTD), S373P, S375F, T376A, and D405N in receptor-binding domain (RBD), D614G, H655Y, N679K, and P681H at the furin cleavage site, N764K and D796K in fusion peptide, and Q954H and N969K in heptapeptide repeat sequence (HR)1. Notably, BA.2.43 exhibited a novel mutation of E1202Q in the C terminal. Other sites included ORF1a harboring 13 mutations followed by ORF1b (6), ORF3a (2), and ORF6 and ORF8 (1 mutation each).ConclusionBA.2 followed by BA.2.38 was the predominant Omicron lineage circulating in Chhattisgarh. BA.2.75 could supersede other Omicron due to its mutational consortium advantage. The periodical genomic monitoring of Omicron variants is thus required for real-time assessment of circulating strains and their mutational-induced severity

MUSiC : a model-unspecific search for new physics in proton-proton collisions at root s=13TeV

Results of the Model Unspecific Search in CMS (MUSiC), using proton-proton collision data recorded at the LHC at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1), are presented. The MUSiC analysis searches for anomalies that could be signatures of physics beyond the standard model. The analysis is based on the comparison of observed data with the standard model prediction, as determined from simulation, in several hundred final states and multiple kinematic distributions. Events containing at least one electron or muon are classified based on their final state topology, and an automated search algorithm surveys the observed data for deviations from the prediction. The sensitivity of the search is validated using multiple methods. No significant deviations from the predictions have been observed. For a wide range of final state topologies, agreement is found between the data and the standard model simulation. This analysis complements dedicated search analyses by significantly expanding the range of final states covered using a model independent approach with the largest data set to date to probe phase space regions beyond the reach of previous general searches.Peer reviewe
