Comparing the degree of pelvic pain with the macroscopic features of endometriosis
Background: Endometriosis is considered as the chronic benign gynecologic disease which can cause chronic pelvic pain (CPP) and infertility. Endometriosis has affected almost 10% of the women of reproductive age.Methods: Thirty women diagnosed with endometriosis were studied. Pain intensity was assessed by visual analogue scale (VAS) and categorized as mild, moderate or severe accordingly. This was followed by laparoscopy/ laparotomy and staging of endometriosis which was done as per the American Society for Reproductive Medicine (ASRM) classification system. Corrective procedures were done simultaneously.Results: Mean age of women with endometriosis was 30±5.75 years. Majority had superficial implants (30%), 6.66% had deep implants and 6.66% had combination of superficial and deep implants. There was no significant difference between implants and severity of pain (p=0.069). There was a significant association between severity of pain with obliteration of POD. Significant association was seen between deeply infiltrating endometriosis (DIE) represented by the pouch of Douglas (POD) obliteration and severity of pain.Conclusions: Severity of pain was significantly associated with deeply infiltrating endometriosis (DIE) represented by the pouch of Douglas (POD) obliteration. However, no association was obtained between severities of pain with superficial implants
Role of urodynamics in evaluation of lower urinary tract dysfunction in women of pelvic organ prolapse
Background: Utero-vaginal prolapse is a common gynecological disorder, result from weakness of musculoskeletal structure that support the pelvic organ. Although it is not an emergency situation but severely affect the quality of life. Women with utero-vaginal prolapse may present with lower urinary tract dysfunction but association of urological changes with UV prolapse and beneficial effect of surgery on these changes is still debatable. Urodynamic study such as cystometry and uroflowmetry help in better understanding of lower urinary tract dysfunction and assist to plan appropriate surgical management thereby reduce chances of postoperative voiding dysfunction.Methods: A total of 30 women of pelvic organ prolapse with lower urinary tract dysfunction, over a period of one year, were subjected to urodynamic studies after thorough evaluation by history, examination and standardized questionnaire both pre and post operatively and data analysed.Results: In present study, urodynamic study identified urinary dysfunction in 93.34% of women recruited in study. Obstruction was present in 36.67% of women. Detrusor overactivity along with obstruction was seen in 20.00% of women. Urodynamic stress incontinence and urodynamic stress incontinence along with obstruction was identified in 13.33% of women each and detrusor overactivity was observed in 10.00% of women.Conclusions: In present study it was found that, if surgical management of pelvic organ prolapse is planned according to urodynamic study, it will improve urologic profile of patients. To conclude that urodynamic study should be an integral part of diagnostic work up of uterovaginal prolapse patients require larger sample size and at least 6 months follow-up duration after surgery
A comparative study of clinical outcomes of post placental insertion versus interval insertion of Copper T 380A intrauterine device
Background: The objective of this study was to study the safety and efficacy of PPIUCD insertion and to compare it with interval insertion.Methods: A prospective study was conducted enrolling 100 women as study group (PPIUCD) and 100 as control group (interval CuT insertion). All women were followed up for 6 months and clinical outcomes were measured in terms of safety, efficacy, effect on menstrual cycles and continuation rates. Chi square test was used to detect differences in the rate of clinical outcomes, and P <0.05 was considered statistically significant.Results: Spontaneous expulsions were more in study group, but the difference was not significant. Number of women having missing thread was significantly higher in study group. Total number of CuT removals and incidence of pelvic infection were significantly higher in controls. Number of women complaining of menorrhagia were more in control group and continuation rate at 6 months was higher in study group, but this difference was not statistically significant. No case of pregnancy or perforation occurred in either group.Conclusions: PPIUCD is an effective, safe, convenient, low cost and long term method of post-partum contraception
Retrospective review of maternal deaths and maternal near misses due to major obstetric haemorrhage at a tertiary care centre in India
Background: Maternal near miss (MNM) is now widely accepted as a better indicator of maternal health than maternal death and reflects the quality of obstetric care in a particular institution.Methods: This is a retrospective study conducted at Lady Hardinge Medical College and Smt. Sucheta Kriplani Hospital over a period of 12 months (April 2016-March 2017), of all cases of maternal death and near miss maternal deaths due to major obstetric haemorrhage(MOH).Results: During the period reviewed, there were 13,083 deliveries, 12,958 live births and 37 maternal deaths. There were 30 cases of near miss maternal deaths and 2 maternal mortalities due to MOH. The mortality index was 6.25%. Severe maternal outcome ratio (SMOR) was 2.46.Among the near miss cases (n=30), morbidly adherent placenta was the cause in 26.6% of cases(n=8), postpartum hemorrhage in 23% of cases(n=7); rupture uterus in 13% cases(n=4); massive abruption in 13% of cases(n=4) and placenta praevia with antepartum haemorrhage in 3% of cases(n=1). Early obstetric haemorrhage due to ruptured ectopic pregnancy and incomplete abortion resulted in MNM in 16% (n=5) and 3.3% (n=1) cases respectively.It was observed that in 40% (n=12) of MNM cases (8 cases of morbidly adherent placenta plus 4 cases of rupture uterus), previous cesarean section was the single most important causative factor for the morbidity of the patient.Conclusions: Reduction in cesarean section rates is imperative to reduce morbidity and mortality associated with MOH.
Secure and Efficient Multi-Key FHE Scheme Supporting Multi-bit Messages from LWE Preserving Non-Interactive Decryption
We consider multi-key fully homomorphic encryption (multi-key FHE) which is the richest variant of fully homomorphic encryption (FHE) that allows complex computation on encrypted data under different keys. Since its introduction by Lopez-Alt, Tromer and Vaikuntanathan in 2012, numerous proposals have been presented yielding various improvements in security and efficiency. However, most of these multi-key FHE schemes encrypt a single-bit message. Constructing a multi-key FHE scheme encrypting multi-bit messages have been notoriously difficult without loosing efficiency for homomorphic evaluation and ciphertext extension under additional keys. In this work, we study multi-key FHE that can encrypt multi-bit messages. Motivated by the goals of improving the efficiency, we propose a new construction with non-interactive decryption and security against chosen-plaintext attack (IND-CPA) from the standard learning with errors (LWE) assumption. We consider a binary matrix as plaintext instead of a single-bit. Our approach supports efficient homomorphic matrix addition and multiplication. Another interesting feature is that our technique of extending a ciphertext under additional keys yields significant reduction in the computational overhead. More interestingly, when contrasted with the previous multi-key FHE schemes for multi-bit messages, our candidates exhibits favorable results in the length of the secret key, public key and ciphertext preserving non-interactive decryption.
Keywords: lattice based cryptosystem, multi-key fully homomorphic encryption, learning with errors, multi-bit message
HIGH-THROUGHPUT SCREENING AND DYNAMIC STUDIES OF SELECTED COMPOUNDS AGAINST SARS-COV-2
Objective: This study was aimed to analyze the inhibitory effect of the drugs used in nanocarrier as well as nanoparticles formulation based drug delivery system selected from PubChem database literature against 3CLpro (3C-like protease) receptor of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) by implementing several in silico analysis techniques.
Methods: This paper detailed a molecular docking-based virtual screening of 5240 compounds previously utilized in nanoparticle and nanocarrier drug delivery systems utilizing AutoDock Vina software on 3CL protease to discover potential inhibitors using a molecular docking technique.
Results: According to the results of the screening, the top two compounds, PubChem Id 58823276 and PubChem Id 60838 exhibited a high affinity for the 3CL protease binding region. Their binding affinities were-9.6 and-8.5 kJ/mol, indicating that they were tightly bound to the target receptor, respectively. These results outperformed those obtained using the co-crystallized native ligand, which exhibited a binding affinity of-7.4 kJ/mol. PubChem Id 60838, the main hit compound in terms of both binding affinity and ADMET analysis, displayed substantial deformability after MD simulation. As a result of the VS and molecular docking techniques, novel 3CL protease inhibitors from the PubChem database were discovered using the Lipinski rule of five and functional molecular contacts with the target protein, as evidenced by the findings of this work.
Conclusion: The findings suggest that the compounds discovered may represent attractive opportunities for the development of COVID-19 3CLpro inhibitors and that they need further evaluation and investigation
Effect of antibiotics on inflammatory marker (IL-6) and perinatal outcomes in women with preterm premature rupture of membranes
Background: The aim is to study the effect of antibiotics on inflammatory marker (IL-6) and perinatal outcomes in women with preterm premature rupture of membranes (PPROM).Methods: 60 women with PPROM at 28–34 weeks of gestation were enrolled in the study. All the women were given antibiotics as per hospital protocol and were subjected to blood sampling for Interleukin -6(IL-6) at admission, delivery and umbilical cord blood. IL-6 levels were assessed for associations with adverse perinatal outcomes and the effect of antibiotic treatment on IL-6 and perinatal outcomes were studied. The data were analyzed using t test and χ2 test.Results: Increased level of IL-6 was associated with chorioamnionitis and neonatal sepsis (p<0.001). High level of IL-6 led to early delivery and complete course of antibiotics suppressed IL-6 (p<0.001) and clinical chorioamnionitis in women with PROM. Full course of antibiotics also decreased the admission rate of babies to neonatal intensive care unit and suppressed respiratory distress syndrome, neonatal sepsis.Conclusions: Increased level of IL-6 is seen in women with chorioamnionitis and neonatal sepsis. Antibiotics suppress the IL-6 levels, chorioamnionitis and neonatal sepsis
Antiviral treatment for acute retinal necrosis:A systematic review and meta-analysis
Acute retinal necrosis is a progressive intraocular inflammatory syndrome characterized by diffuse necrotizing retinitis that can lead to a poor visual outcome, mainly from retinal detachment. The antiviral treatment approach for acute retinal necrosis varies as there are no established guidelines. We summarize the outcomes of acute retinal necrosis with available antiviral treatments. Electronic searches were conducted in PubMed/MEDLINE, EMBASE, Scopus, and Google Scholar for interventional and observational studies. Meta-analysis was performed to evaluate the pooled proportion of the predefined selected outcomes. This study was registered in PROSPERO (CRD42022320987). Thirty-four studies with a total of 963 participants and 1,090 eyes were included in the final analysis. The estimated varicella-zoster virus and herpes simplex virus polymerase chain reaction-positive cases were 63% (95% CI: 55–71%) and 35% (95% CI: 28–42%), respectively. The 3 main antiviral treatment approaches identified were oral antivirals alone, intravenous antivirals alone, and a combination of systemic (oral or intravenous) and intravitreal antivirals. The overall pooled estimated proportions of visual acuity improvement, recurrence, and retinal detachment were 37% (95% CI: 27–47%), 14% (95% CI: 8–21%), and 43% (95% CI: 38–50%), respectively. Patients treated with systemic and intravitreal antivirals showed a trend towards better visual outcomes than those treated with systemic antivirals (oral or intravenous) alone, even though this analysis was not statistically significant (test for subgroup differences P = 0.83).</p
Global age-sex-specific mortality, life expectancy, and population estimates in 204 countries and territories and 811 subnational locations, 1950–2021, and the impact of the COVID-19 pandemic: a comprehensive demographic analysis for the Global Burden of Disease Study 2021
Background: Estimates of demographic metrics are crucial to assess levels and trends of population health outcomes. The profound impact of the COVID-19 pandemic on populations worldwide has underscored the need for timely estimates to understand this unprecedented event within the context of long-term population health trends. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides new demographic estimates for 204 countries and territories and 811 additional subnational locations from 1950 to 2021, with a particular emphasis on changes in mortality and life expectancy that occurred during the 2020–21 COVID-19 pandemic period. Methods: 22 223 data sources from vital registration, sample registration, surveys, censuses, and other sources were used to estimate mortality, with a subset of these sources used exclusively to estimate excess mortality due to the COVID-19 pandemic. 2026 data sources were used for population estimation. Additional sources were used to estimate migration; the effects of the HIV epidemic; and demographic discontinuities due to conflicts, famines, natural disasters, and pandemics, which are used as inputs for estimating mortality and population. Spatiotemporal Gaussian process regression (ST-GPR) was used to generate under-5 mortality rates, which synthesised 30 763 location-years of vital registration and sample registration data, 1365 surveys and censuses, and 80 other sources. ST-GPR was also used to estimate adult mortality (between ages 15 and 59 years) based on information from 31 642 location-years of vital registration and sample registration data, 355 surveys and censuses, and 24 other sources. Estimates of child and adult mortality rates were then used to generate life tables with a relational model life table system. For countries with large HIV epidemics, life tables were adjusted using independent estimates of HIV-specific mortality generated via an epidemiological analysis of HIV prevalence surveys, antenatal clinic serosurveillance, and other data sources. Excess mortality due to the COVID-19 pandemic in 2020 and 2021 was determined by subtracting observed all-cause mortality (adjusted for late registration and mortality anomalies) from the mortality expected in the absence of the pandemic. Expected mortality was calculated based on historical trends using an ensemble of models. In location-years where all-cause mortality data were unavailable, we estimated excess mortality rates using a regression model with covariates pertaining to the pandemic. Population size was computed using a Bayesian hierarchical cohort component model. Life expectancy was calculated using age-specific mortality rates and standard demographic methods. Uncertainty intervals (UIs) were calculated for every metric using the 25th and 975th ordered values from a 1000-draw posterior distribution. Findings: Global all-cause mortality followed two distinct patterns over the study period: age-standardised mortality rates declined between 1950 and 2019 (a 62·8% [95% UI 60·5–65·1] decline), and increased during the COVID-19 pandemic period (2020–21; 5·1% [0·9–9·6] increase). In contrast with the overall reverse in mortality trends during the pandemic period, child mortality continued to decline, with 4·66 million (3·98–5·50) global deaths in children younger than 5 years in 2021 compared with 5·21 million (4·50–6·01) in 2019. An estimated 131 million (126–137) people died globally from all causes in 2020 and 2021 combined, of which 15·9 million (14·7–17·2) were due to the COVID-19 pandemic (measured by excess mortality, which includes deaths directly due to SARS-CoV-2 infection and those indirectly due to other social, economic, or behavioural changes associated with the pandemic). Excess mortality rates exceeded 150 deaths per 100 000 population during at least one year of the pandemic in 80 countries and territories, whereas 20 nations had a negative excess mortality rate in 2020 or 2021, indicating that all-cause mortality in these countries was lower during the pandemic than expected based on historical trends. Between 1950 and 2021, global life expectancy at birth increased by 22·7 years (20·8–24·8), from 49·0 years (46·7–51·3) to 71·7 years (70·9–72·5). Global life expectancy at birth declined by 1·6 years (1·0–2·2) between 2019 and 2021, reversing historical trends. An increase in life expectancy was only observed in 32 (15·7%) of 204 countries and territories between 2019 and 2021. The global population reached 7·89 billion (7·67–8·13) people in 2021, by which time 56 of 204 countries and territories had peaked and subsequently populations have declined. The largest proportion of population growth between 2020 and 2021 was in sub-Saharan Africa (39·5% [28·4–52·7]) and south Asia (26·3% [9·0–44·7]). From 2000 to 2021, the ratio of the population aged 65 years and older to the population aged younger than 15 years increased in 188 (92·2%) of 204 nations. Interpretation: Global adult mortality rates markedly increased during the COVID-19 pandemic in 2020 and 2021, reversing past decreasing trends, while child mortality rates continued to decline, albeit more slowly than in earlier years. Although COVID-19 had a substantial impact on many demographic indicators during the first 2 years of the pandemic, overall global health progress over the 72 years evaluated has been profound, with considerable improvements in mortality and life expectancy. Additionally, we observed a deceleration of global population growth since 2017, despite steady or increasing growth in lower-income countries, combined with a continued global shift of population age structures towards older ages. These demographic changes will likely present future challenges to health systems, economies, and societies. The comprehensive demographic estimates reported here will enable researchers, policy makers, health practitioners, and other key stakeholders to better understand and address the profound changes that have occurred in the global health landscape following the first 2 years of the COVID-19 pandemic, and longer-term trends beyond the pandemic
