PHARMACOVIGILANCE: DYNAMICS IN INDIAN PHARMA INDUSTRY

Pharmacovigilance refers to the process of identifying, detecting, and responding to drug safety issue and has witnessed dynamic advancements in pharmaceutical industries throughout the world. The main objective of pharmacovigilance is to extend the safety monitoring and to detect any ADRs that previously got unrecognized in evolution during clinical trial. ADRs monitoring is required for each medicine throughout its lifecycle which includes early stage of drug design, clinical trials, and post marketing surveillance. The emerging trend in pharmacovigilance is to link the pre marketing data with the data collected during post marketing phase that include safety information. India is a vast country with population of over 1.32 Billion with different social economics status, different patterns of disease prevalence it becomes more important to have a standardized and robust pharmacovigilance. Pharmacists, as doctor remark that their involvement may increase the reporting rate and have a greater role to play in the area of pharmacovigilanc

Dobbs V. Jackson Women's Health Organization (2022): A Case Comment

In June 2022, the US Supreme Court, in Dobbs v. Jackson with a 6:3 majority, overruled Roe and Casey and took away the constitutional right to abortion. The right was implicitly based on, among other things, the Liberty interest protected by the Fourteenth Amendment's Due Process Clause. In denying the right, the Supreme Court reasoned that to bring a new component of right into liberty, one must show that it was reasonably accepted as a right when the Fourteenth Amendment was adopted and ratified. Any other interpretation, the court held, would not be faithful to the constitutional text. In this commentary, it is argued that the court's historical analysis is a rudimentary method for interpreting abstract concepts like liberty which was envisaged for eternity. The case comment demonstrates that historically chained understanding of the constitutional text, especially its rights, is not instance best way to show fidelity to the constitutional text. The difference between "original meaning" and "original expected application" is significant. The comment further shows the judgment's possible unintended—but still cruel—consequence. Finally, it is concluded with a proposed alternative method of Reflective Equilibrium with an aspiration of visualising a seamless web of the components of the liberty principle

Effect of letrozole 2.5 mg or 5.0 mg for ovulation induction in intrauterine insemination in case of unexplained infertility: a randomized controlled trial

Background: Aim was to compare effects of letrozole 2.5 mg or 5.0 mg for ovulation induction in patients with unexplained Infertility. Methods: A randomized controlled trial. 60 patients attending infertility clinic were randomly allocated into two groups-Group A received letrozole 2.5 mg and Group B received letrozole 5 mg orally for 5 days from 3rd day of cycle. The patients also received inj FSH 75 IU i/m on day 7 and 9 of the cycle and underwent follicular study on day 11, 13, 15. When the dominant follicle size reached 18 mm ovulation triggered with Inj hCG 5000 IU IM and Intrauterine insemination was done 24-36 hours later. Pregnancy rates were calculated. Results were analysed by statistical software. Results: Better ovulation rates were seen in patients receiving 5 mg letrozole. No difference in the pregnancy rates was found between the two groups. No multiple pregnancies and ovarian hyperstimulation seen. Conclusions: It appears that 5 mg daily for 5 days is a preferable letrozole dose for superovulation

Hierarchical classification for Multilingual Language Identification and Named Entity Recognition

ABSTRACT This paper describes the approach for Subtask-1 of the FIRE-2015 Shared Task on Mixed Script Information Retrieval. The subtask involved multilingual language identification (including mixed words and anomalous foreign words), named entity recognition (NER) and subclassification. The proposed methodology starts with cleaning the data and then extracting structural and contextual features from the text for further processing. A subset of these features is selected (based on validation) for training supervised classifiers, separately for language identification and NER. Finally, they are applied hierarchically to annotate the entire text. The detected named entities are further subclassified by a novel unsupervised technique based on query refinement and keyword based scoring. The proposed approach on the testing dataset of the shared task showed promising results with a weighed F-measure of 0.8082. However, it is worth noting that the classifiers have been sub-optimal with respect to discriminating between certain linguistically similar languages (for e.g., Gujarati in Hindi and Gujarati pairs). The proposed approach is flexible and robust enough to handle additional languages for identification as well as anomalous foreign or extraneous words. The implementation of the approach has also been shared for the purpose of future research usage

Molecular surveillance of dengue virus in field-collected Aedes mosquitoes from Bhopal, central India: evidence of circulation of a new lineage of serotype 2

IntroductionDengue fever is hyperendemic in several Southeast and South Asian countries, including India, with all four serotypes (DENV 1–4) circulating at different periods and in different locations. Sustainable and improved virological and entomological surveillance is the only tool to prevent dengue and other vector-borne diseases.ObjectivesThe present study has been carried out to detect and characterize the circulating dengue virus (DENV) in field-collected Aedes mosquitoes in Bhopal, Central India.MethodsAedes mosquitoes were collected from 29 localities within Bhopal city during October 2020 to September 2022. DENV infection was assessed in the individual head and thorax regions of Aedes mosquitoes using reverse transcriptase PCR. Positive samples were sequenced, and the circulating serotypes and genotypes were determined using phylogenetic analysis.ResultsDENV RNA was detected in 7 Aedes aegypti and 1 Aedes albopictus, with infection rates of 0.59 and 0.14%, respectively. Phylogenetic analysis revealed all the isolates belonged to DENV serotype 2 and distinctly clustered with the non-Indian lineage (cosmopolitan genotype 4a), which was not recorded from the study area earlier. The time to most common recent ancestor (TMRCA) of these sequences was 7.4 years old, with the highest posterior density (HPD) of 3.5–12.2 years, indicating that this new lineage emerged during the year 2014. This is the first report on the DENV incrimination in both Ae. aegypti and Ae. albopictus mosquitoes collected from Bhopal, Central India.ConclusionThe observed emergence of the non-Indian lineage of DENV-2 in Bhopal, which again is a first report from the area, coincides with the gradual increase in DENV cases in Bhopal since 2014. This study emphasizes the importance of DENV surveillance and risk assessment in this strategically important part of the country to decipher its outbreak and severe disease-causing potential

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV
