Utility of opportunistic screening to assess the impact of urinary incontinence on quality of life and barriers to seeking treatment among women attending a tertiary healthcare centre in North India.

INTRODUCTION: Urinary incontinence (UI) is a common but frequently neglected problem in females, significantly impacting their psychosocial health. The available estimates are an underestimation of a bigger problem. Thus, the study aimed to estimate the prevalence of UI, its associated risk factors, its impact on the Quality of life (QoL), and barriers to treatment-seeking behaviour in women attending tertiary healthcare centres. METHODS: We conducted a cross-sectional study using an opportunistic screening among women visiting a tertiary care hospital in Punjab recruited using multi-stage systematic random sampling. UI was classified as Stress (SUI), Urge (UUI), mixed (MUI), and No Incontinence (UI less than once a week or a month or no complaints) using the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). Bivariate analyses were done using the chi-square test to test the association between the dependent and independent variables. The predictors of UI were explored using univariable and multivariable binary logistic regression and depicted using Odds ratio with 95% confidence intervals. The impact of UI on Quality of Life (QoL) was assessed using the Incontinence Impact Questionnaire-Short Form (IIQ-7), and compared among the three UI types using One-Way ANOVA. Treatment barriers were explored using open-ended questions. RESULTS: Of the 601 women, 19.6% reported UI (stress UI: 10.1%, mixed UI: 6.0%, and urge UI: 3.5%). There were significant clinical-social factors that predicted different types of UI. The UI depicted a significant effect on QoL across all domains of the IIQ-7 (total mean score: 50.8 ± 21.9) compared to women with no incontinence (0.1 + 1.9). The score was highest in women with MUI, followed by SUI and UUI. About two-thirds of the affected women never consulted a doctor and considered it a non-serious condition or a normal ageing process. CONCLUSIONS: The present study found a high prevalence of UI through opportunistic screening across all the women's age groups with different conditions. Due to the associated stigma, clinicians should make every attempt to talk more about this, especially in women with medical conditions that can precipitate UI. Furthermore, the results call for generating more robust estimates through community-based screening studies.

Nano-Biotechnology for Bacteria Identification and Potent Anti-bacterial Properties: A Review of Current State of the Art.

Sepsis is a critical disease caused by the abrupt increase of bacteria in human blood, which subsequently causes a cytokine storm. Early identification of bacteria is critical to treating a patient with proper antibiotics to avoid sepsis. However, conventional culture-based identification takes a long time. Polymerase chain reaction (PCR) is not so successful because of the complexity and similarity in the genome sequence of some bacterial species, making it difficult to design primers and thus less suitable for rapid bacterial identification. To address these issues, several new technologies have been developed. Recent advances in nanotechnology have shown great potential for fast and accurate bacterial identification. The most promising strategy in nanotechnology involves the use of nanoparticles, which has led to the advancement of highly specific and sensitive biosensors capable of detecting and identifying bacteria even at low concentrations in very little time. The primary drawback of conventional antibiotics is the potential for antimicrobial resistance, which can lead to the development of superbacteria, making them difficult to treat. The incorporation of diverse nanomaterials and designs of nanomaterials has been utilized to kill bacteria efficiently. Nanomaterials with distinct physicochemical properties, such as optical and magnetic properties, including plasmonic and magnetic nanoparticles, have been extensively studied for their potential to efficiently kill bacteria. In this review, we are emphasizing the recent advances in nano-biotechnologies for bacterial identification and anti-bacterial properties. The basic principles of new technologies, as well as their future challenges, have been discussed.

Multiepitope glycan based laser assisted fluorescent nanocomposite with dual functionality for sensing and ablation of Pseudomonas aeruginosa.

Pseudomonas aeruginosa (P. aeruginosa) infection is becoming a severe health hazard and needs early diagnosis with high specificity. However, the non-specific binding of a biosensor is a challenge to the current bacterial detection system. For the first time, we chemically synthesized a galactose tripod (GT) as a P. aeruginosa-specific ligand. We conjugated GT to a photothermally active fluorescent nanocomposite (Au@SiO2-TCPP). P. aeruginosa can be detected using Au@SiO2-TCPP-GT, and additionally ablated as well using synergistic photothermal and photodynamic therapy. Molecular dynamics and simulation studies suggested better binding of GT (binding energy = -6.6 kcal mol-1) with P. aeruginosa lectin than that of galactose monopod (GM) (binding energy = -5.9 kcal mol-1). Furthermore, a binding study was extended to target P. aeruginosa, which has a galactose-binding carbohydrate recognition domain receptor. The colorimetric assay confirmed a limit of detection (LOD) of 104 CFU mL-1. We also looked into the photosensitizing property of Au@SiO2-TCPP-GT, which is stimulated by laser light (630 nm) and causes photoablation of bacteria by the formation of singlet oxygen in the surrounding media. The cytocompatibility of Au@SiO2-TCPP-GT was confirmed using cytotoxicity assays on mammalian cell lines. Moreover, Au@SiO2-TCPP-GT also showed non-hemolytic activity. Considering the toxicity analysis and efficacy of the synthesized glycan nanocomposites, these can be utilized for the treatment of P. aeruginosa-infected wounds. Furthermore, the current glycan nanocomposites can be used for bacterial detection and ablation of P. aeruginosa in contaminated food and water samples as well.

Case 314: Cerebral Proliferative Angiopathy.

HISTORY: An 18-year-old man presented to the neurosurgery outpatient department with recurrent episodes of epistaxis for the past 8 years and altered behavior for the past month. Epistaxis was scanty in amount, intermittent, spontaneous, and not associated with any trauma or nasal obstruction or breathing difficulties. Bleeding used to stop spontaneously after some time. There was no history of associated headache, seizures, vomiting, fever, or loss of consciousness. On physical examination, the patient was afebrile, with normal vital signs and normal Glasgow Coma Scale score (15 of 15) at the time of presentation. Multiple dilated engorged veins were visible on the forehead; however, there was no evidence of abnormal skin pigmentation. Neurologic examination yielded findings that were within normal limits. Laboratory examinations revealed a hemoglobin level of 11 g/dL (normal range, 13.2-16.6 g/dL), with the rest of the parameters within normal limits. This patient underwent unenhanced CT of the brain and paranasal sinuses followed by contrast-enhanced MRI of the brain for further evaluation.

Treatment with fibroblast growth factor 19 increases skeletal muscle fiber size, ameliorates metabolic perturbations and hepatic inflammation in 5/6 nephrectomized mice.

Chronic kidney disease (CKD) is associated with osteosarcopenia, and because a physical decline in patients correlates with an increased risk of morbidity, an improvement of the musculoskeletal system is expected to improve morbi-mortality. We recently uncovered that the intestinal hormone Fibroblast Growth Factor 19 (FGF19) is able to promote skeletal muscle mass and strength in rodent models, in addition to its capacity to improve glucose homeostasis. Here, we tested the effects of a treatment with recombinant human FGF19 in a CKD mouse model, which associates sarcopenia and metabolic disorders. In 5/6 nephrectomized (5/6Nx) mice, subcutaneous FGF19 injection (0.1 mg/kg) during 18 days increased skeletal muscle fiber size independently of food intake and weight gain, associated with decreased gene expression of myostatin. Furthermore, FGF19 treatment attenuated glucose intolerance and reduced hepatic expression of gluconeogenic genes in uremic mice. Importantly, the treatment also decreased gene expression of liver inflammatory markers in CKD mice. Therefore, our results suggest that FGF19 may represent a novel interesting therapeutic strategy for a global improvement of sarcopenia and metabolic complications in CKD.

Association of minimum dietary diversity with anaemia among 6-59 months' children from rural India: An evidence from a cross-sectional study.

Introduction: Anaemia is one of the micronutrient deficiency disorders that have global public health implications. The present study aims to determine the association of minimum dietary diversity (MDD) with anaemia among children aged 6-59 months in rural North India. Methods: In Rohtak (a north Indian city), a cross-sectional survey was conducted in 2018-19 (n = 266). Univariate and bivariate analyses were performed. The Chi-square test was used for assessing the significance level during bivariate analysis. Further, multivariable regression analysis was used for determining the factors for anaemia prevalence among children aged 6-59 months. Results: About 62.4% (n = 166) of the children aged 6-59 months were found to have anaemia in the study area. The prevalence of MDD was 35.3% (n = 94). It was found that children with no MDD have a higher prevalence of moderate (42% vs. 25.5%; P < 0.001) and severe (12.8% vs. 8.5%; P < 0.001) anaemia. It was revealed that the children with no MDD had a significantly higher likelihood of being anaemic than children with MDD in model-1 [aOR: 2.09; CI: 1.23, 3.55] and model-3 [aOR: 1.70; CI: 1.01, 3.01]. Children with mothers who never attended school had significantly higher odds for anaemia in reference to those children whose mothers ever attended school in model-2 [aOR: 3.62; CI: 2.07,6.34] and model-3 [aOR: 3.00; CI: 1.62,5.56]. Conclusion: Measures to alleviate under-five anaemia should include empowering and educating women, expanding access to supplementation, fortification programmes, and promoting and raising awareness about feeding diverse foods, while also considering the socioeconomic status.

Correlates of post-partum intra-uterine copper-T devices (PPIUCD) acceptance and retention: an observational study from North India.

BACKGROUND: Postpartum intrauterine contraceptives device (PPIUCD) offers an effective means of providing contraceptive services to women in countries with high rates of unmet needs for family planning services. However, scientific literature estimating the long-term retention rates is scarce. We estimate the factors affecting acceptance and retention of PPIUCD and explore the risk factors against PPIUCD Discontinuation at six months". MATERIAL AND METHOD: This prospective observational study was conducted between 2018 and 20 at a tertiary care institute in North India. PPIUCD was inserted following a detailed counseling session and consent. The women were followed up for six months. Bivariate analysis was done to depict the association between socio-demographic characteristics and acceptance. Logistic regression, cox regression, and Kaplan Meier analysis were applied to explore factors affecting acceptance and retention of PPIUCD. RESULTS: Of the 300 women counseled for PPIUCD, 60% accepted them. The majority of these women were between 25 and 30 years (40.6%), primigravida (61.7%), educated (86.1%), and from urban areas (61.7%). Retention rates at six months were about 65.6%, while 13.9% and 5.6% were either removed or expelled. Women declined PPIUCD due to refusal by spouses, partial knowledge, inclination towards other methods, non-willingness, religious beliefs, and fear of pain and heavy bleeding. Adjusted logistic regression depicted that higher education, housewife status, lower-middle and richest SES, Hinduism, and counseling in early pregnancy promoted acceptance of PPIUCD. The most common reasons for removal were AUB, infection, and family pressure (23.1%). Adjusted hazard ratio depicted religion other than Hinduism, counseling in late stages of pregnancy, and normal vaginal delivery were significant predictors for early removal or expulsion. While education, higher socio-economic status favoured retention. CONCLUSION: PPIUCD is a safe, highly effective, low-cost, long-acting, and feasible method of contraception. Skill enhancement of healthcare personnel for insertion techniques, adequate antenatal counseling, and advocacy of PPIUCD can help increase the acceptance of PPIUCD.

Unusual case of a leiomyoma in the space of Retzius mimicking broad ligament fibroid.

This case report will discuss an interesting case of a patient who presented with pain in the lower abdomen of 2-month duration. Clinical examination and imaging findings were suggestive of a broad ligament fibroid. However, intraoperatively, the mass was found to be present in the space of Retzius, which is an extremely rare location for such a pathology. The access to the tumour was very challenging. Successful surgical excision was done with the help of a multidisciplinary team involving a gynaecologist, a urologist and an anaesthetist. Histopathology reported it to be benign leiomyoma. Postoperatively, the patient made an uneventful recovery.

Vulvar leiomyoma in an adolescent girl: a case report and review of the literature.

BACKGROUND: Vulvar leiomyoma is a rare soft tissue tumor, with only around 300 cases described in the literature. Owing to its low incidence of just 0.03% of all gynecological tumors, it often poses a great diagnostic challenge, especially in teenagers. We report this rare occurrence of vulvar leiomyoma in a teenage girl who was primarily left untreated due to cultural taboos and fear of loss of virginity. The main aim in presenting such rare case studies is to raise awareness and expand the diagnostic horizon of the surgeon for appropriate management. CASE PRESENTATION: We describe a case of a 15-year-old North Indian, sexually inactive unmarried girl, who presented with a history of painless swelling in the left labia majora for the last 1 year, which gradually increased in size. There was no associated pain or any other difficulty. Local examination revealed a 14 × 10 cm solid, unilateral nonpedunculated mass on the left labia majora with superficial vascularity. Differential diagnoses of sarcoma, lipoma, Bartholin cyst, and fibroid were kept in mind. Ultrasonography revealed a solid mass with superficial vascularity with normal internal genitalia. The mass was enucleated with an intact capsule under anesthesia. Histopathology confirmed it to be benign vulvar leiomyoma. The patient was discharged after 3 days in a satisfactory condition. CONCLUSION: Leiomyoma of the vulva is an exceptionally rare tumor and is seldom seen in teenagers. It is often misinterpreted as a Bartholin cyst and should be kept as one of the differential diagnosis in teenage girls presenting with unilateral vulvar swelling. Vulvar leiomyoma can be completely cured by surgical removal if diagnosed timely without compromising virginity, so should never be missed in adolescents.

Identification and differential expression of long non-coding RNAs and their association with XIST gene during early embryonic developmental stages of Bos taurus.

X-chromosomes inactivation (XCI) is a phenomenon that aims to equalize the dosage of X-linked gene products between XY males and XX females in mammals. XIST gene is the master regulator of X chromosome inactivation during early embryonic developmental stages of Bos taurus. Biological molecule such as lncRNA plays significant role in the control of XCI, by RNA-based regulatory mechanisms and are non-coding regions of the genome. In our study, using in-silico transcriptome data analysis approach, we analysed RNA-seq data of E35, E39 and E43 samples from bovine genital ridges of early embryonic stages, and identified lncRNA transcripts. More than 7 lakh lncRNA transcripts were identified. Further, our study identified DE-lncRNAs and genes between male and female and studied their co-expression. More than four thousand differentially expressed lncRNAs identified. The co-expression and RT-PCR study in the result showed that there exists an association between the XIST and DE-lncRNAs in early embryonic gonads of bovine at E35. In this study, the association between DE-lncRNAs and XIST gene indicates, the potentially important role of DE-lncRNAs during embryo development in bovine. In conclusion, this study shows there exist an interplay between genes and lncRNAs at transcriptome level of bovine during early embryonic days.

Pre-exposure Prophylaxis (PrEP) Awareness, Willingness to Use, and Preferred Places for Access Among the Cambodian Female Entertainment Workers: A Cross-Sectional Study.

The aim of the study was to determine the awareness, desire to use, and preferred providers of pre-exposure prophylaxis (PrEP) among Female Entertainment Workers (FEWs) aged 18-35 years in Cambodia's Phnom Penh region. Of 1003 FEWs, 31.8% of them had heard of PrEP. When informed about PrEP, 67.4% said they would use PrEP and the most preferred location to access PrEP was a local non-governmental organization (NGO) (63.2%), followed by a government clinic/center (39.8%), ART clinic (26.5%), pharmacy (20.7%), and CBO (14.8%). FEWs who had heard about PrEP (aOR: 2.46; CI: 1.79-3.39) and those with no additional income source other than sex work (aOR: 1.53; CI: 1.16-2.02) were more likely to express their willingness to use PrEP. When the country is in the process of making provisions for PrEP, the study urges policymakers and programmers to take steps towards creating awareness about PrEP among key populations such as FEWs and its availability preferably through local NGOs and government clinics.

Lessons learned from conceptualising and operationalising the National Adolescent Health Programme or Rashtriya Kishor Swasthya Karyakram's Learning Districts Initiative in six districts of India.

In 2018, WHO with the support of the Ministry of Health and Family Welfare, India and partner organisations launched a Learning Districts Initiative to strengthen the district-level application of the National Adolescent Health Programme and to draw out lessons. An assessment of this initiative from 2019 to 2023 using qualitative and quantitative programme monitoring data from interviews, discussions, observations and data from multiple secondary sources explored the evolution of the concept, the process of securing government agreement, operationalising the initiative and the feasibility, acceptability, effectiveness and the potential of sustainability and replicability within the government health system. As part of the process, WHO developed the concept with partners to address the challenges identified in a Rapid Programme Review requested by the Ministry. The Ministry concurred with the proposed participatory problem identification and problem-solving approach. A review-based process guided the implementation. Local non-government organisations supported District Health Management Units to strengthen planning, implementation and monitoring. An expert in adolescent health provided technical oversight. Three years later in 2022, adolescent health is on district agendas, staff capacity has been built, and clinic and community-based activities are carried out in a structured manner. The Initiative is feasible as it leverages local expertise. Its core interventions are acceptable to government officials. While there are improvements in inputs, processes and outputs, these need to be independently validated. Challenges such as unfilled vacancies, problems in supply procurement, inability of staff to discuss sensitive issues, weak intersectoral convergence and low engagement of adolescents in programme management remain to be addressed. Nevertheless, the overall experience augurs well for the future of the programme.

Neglected case of a huge leiomyoma in an elderly postmenopausal woman: a case report.

BACKGROUND: Fibroids are benign tumors of the female reproductive tract originating from the myometrial smooth muscle cells. They are a frequent occurrence in women of childbearing age but their incidence is rare after menopause. In addition, there is a remote possibility of malignant transformation to leiomyosarcoma in less than 1% of cases. CASE PRESENTATION: We hereby report a case of large fibroid in a postmenopausal Indian female with rapid growth, raising the suspicion of malignant transformation into leiomyosarcoma. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Histopathology report confirmed it to be benign leiomyoma without any evidence of neoplasia. CONCLUSION: Sudden enlargement of leiomyoma in postmenopausal women should not be ignored due to possible malignant transformation and is to be dealt immediately with hysterectomy followed by histopathology.

Awareness about Human Papillomavirus Vaccine and Its Uptake among Women from North India: Evidence from a Cross-Sectional Study.

OBJECTIVE: This study aims to estimate the prevalence of human papillomavirus (HPV) vaccine usage and determine the factors for awareness about HPV vaccine among women in reproductive age group. METHODS: This is a cross-sectional survey under a cervical cancer prevention study. The sample size was 1020 women, aged 15-49 years [550 in Delhi and 470 in Rohtak]. Bivariate analysis and Fisher exact test along with binary logistic regression analysis were used to determine the factors for awareness. RESULT: About 18.0 % [Delhi: 24.2 % and Rohtak: 10.9 %] of the respondents had heard about the vaccine against cervical cancer. The women aged more than 30 years [AOR: 1.35; CI: 0.94, 1.94] were more likely to be aware of cervical cancer vaccine as compare to women of 30 years and less. However, the women from Rohtak [AOR: 0.90; CI: 0.48, 1.66] were less likely to be aware of vaccine against cervical cancer in reference to women aged 30 years and more [AOR: 1.61; CI: 1.01, 2.56] from Delhi. About 0.6 % [Delhi: 1.1 % and Rohtak: 0.0 %] of the respondents had received HPV vaccine. CONCLUSION: Women tend to have limited knowledge about cervical cancer vaccine and immunisation practices. The women's demographic makeup varied significantly between the two sites, i.e , Rohtak and Delhi, which had an impact on how well they understood and utilised the cervical cancer vaccination. It is worth mentioning that none of the women from Rohtak had received the immunisation. The awareness of the cervical cancer vaccine among women from the Rohtak was lower than the Delhi women.

Variations in the patterns of tobacco usage among indian females - findings from the global adult tobacco survey India.

BACKGROUND: Males dominate in tobacco usage, as well as in tobacco research, knowing that women face more severe health consequences. There is a specific lack of information on epidemiological statistics, risks, and the level of knowledge among women regarding tobacco. This study examines the Global Adult Tobacco Survey (GATS)-India dataset to estimate female tobacco usage and assess socio-economic variations in tobacco consumption, awareness regarding the adverse effects of tobacco, noticing pack health warnings (PHW), and intention to quit tobacco use well as factors influencing these domains. METHODS: Using a geographically clustered multistage sampling method, the nationally representative GATS II (2016-17) interviewed 40,265 female respondents aged 15 years and above from all Indian states and union territories. Standard operational definitions were used to estimate the primary independent variables (community, individual, and household categories) and dependent variables like awareness regarding the adverse effects of tobacco, noticing pack health warning (PHW), and intention to quit tobacco. Sampling weights were adjusted while performing the analysis. Bivariate and multivariable analysis were used to generate the estimates. RESULTS: Of the total female respondents, 84.2% were never-users, 13.3% ever consumed Smokeless Tobacco (SLT) products, 1.8% ever smoked tobacco, and 0.8% were dual users once in their lives. Around 16% of the women had exposure to Second Hand Smoke (SHS) either at their homes, workplaces or in public places. Overall, maximum awareness was seen among non-smoker females (64.7%) and dual users (64.7%), followed by women exposed to SHS, SLT users, and smokers. PHW was noticed more by the bidi smokers, followed by SLT users and cigarette smokers. Factors that positively affected intention to quit smoking included younger age, secondary school education, self-employed status, the habit of buying packed cigarettes/bidi, believing that smoking causes serious illness, and attempted quitting in the last 12 months. CONCLUSION: A high proportion of women consume tobacco which is significantly influenced by socio-demographic factors. Tobacco regulators should be especially concerned about women as the tobacco marketing experts target them. Mobilizing self-help groups and organizations working for women and children could assist broader campaigns to generate awareness and motivate quitting attempts.

Outdoor Physical Activity in an Air Polluted Environment and Its Effect on the Cardiovascular System-A Systematic Review.

Air pollution is a global public health threat. Evidence suggests that increased air pollution leads to increased cardiovascular morbidity and mortality. The aim of this review was to systematically review and synthesize scientific evidence to understand the effect of performing outdoor physical activity (PA) in a polluted environment on cardiovascular outcomes. This review was developed and reported in accordance with the PRISMA guidelines. Electronic searches in Embase, Web of Science, and PubMed were undertaken through March 2021 initially, and later updated through to 31st January 2022, for observational studies published in peer-reviewed journals that report cardiovascular mortality or morbidity due to outdoor PA in air polluted environment. These searches yielded 10,840 citations. Two reviewers independently reviewed each citation for its eligibility. Seven studies were found to be eligible. Of these, five were cohort studies and two were cross-sectional studies. Pollutants measured in the selected studies were Particulate Matter (PM)-PM10, PM2.5, nitrogen oxides (NOx), and ozone (O3). The most common study outcome was myocardial infarction, followed by cardiovascular mortality, hypertension and heart rate variability. Six studies emphasized that the PA has beneficial effects on cardiovascular outcomes, though air pollutants attenuate this effect to an extent. Two studies showed that walking, even in the polluted environment, significantly reduced the heart rate and heart rate variability indices. The beneficial effects of outdoor PA outweigh the harmful effects of air pollution on cardiovascular health, though the benefits reduce to an extent when PA is carried out in a polluted environment. Because a limited number of studies (n = 7) were eligible for inclusion, the review further emphasizes the critical need for more primary studies that differentiate between outdoor and indoor PA and its effect on cardiovascular health.

In silico prediction of the animal susceptibility and virtual screening of natural compounds against SARS-CoV-2: Molecular dynamics simulation based analysis.

COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. It has six open reading frames (orf1ab, orf3a, orf6, orf7a, orf8, and orf10), a spike protein, a membrane protein, an envelope small membrane protein, and a nucleocapsid protein, out of which, orf1ab is the largest ORF coding different important non-structural proteins. In this study, an effort was made to evaluate the susceptibility of different animals against SARS-CoV-2 by analyzing the interactions of Spike and ACE2 proteins of the animals and propose a list of potential natural compounds binding to orf1ab of SARS-CoV-2. Here, we analyzed structural interactions between spike proteins of SARS-CoV-2 and the ACE2 receptor of 16 different hosts. A simulation for 50 ns was performed on these complexes. Based on post-simulation analysis, Chelonia mydas was found to have a more stable complex, while Bubalus bubalis, Aquila chrysaetos chrysaetos, Crocodylus porosus, and Loxodonta africana were found to have the least stable complexes with more fluctuations than all other organisms. Apart from that, we performed domain assignment of orf1ab of SARS-CoV-2 and identified 14 distinct domains. Out of these, Domain 3 (DNA/RNA polymerases) was selected as a target, as it showed no similarities with host proteomes and was validated in silico. Then, the top 10 molecules were selected from the virtual screening of ∼1.8 lakh molecules from the ZINC database, based on binding energy, and validated for ADME and toxicological properties. Three molecules were selected and analyzed further. The structural analysis showed that these molecules were residing within the pocket of the receptor. Finally, a simulation for 200 ns was performed on complexes with three selected molecules. Based on post-simulation analysis (RMSD, RMSF, Rg, SASA, and energies), the molecule ZINC000103666966 was found as the most suitable inhibitory compound against Domain 3. As this is an in silico prediction, further experimental studies could unravel the potential of the proposed molecule against SARS-CoV-2.

Mechanobactericidal, Gold Nanostar Hydrogel-Based Bandage for Bacteria-Infected Skin Wound Healing.

The emergence of multidrug resistant (MDR) microorganisms has led to the development of alternative approaches for providing relief from microbial attacks. The mechano-bactericidal action as a substitute for antimicrobials has become the focus of intensive research. In this work, nanostructure-conjugated hydrogel are explored as a flexible dressing against Staphylococcus aureus (S. aureus)-infected skin wounds. Herein gold nanostars (AuNst) with spike lengths reaching 120 nm are probed for antibacterial action. The bacterial killing of >95% is observed for Pseudomonas aeruginosa (P. aeruginosa) and Escherichia coli (E. coli), while up to 60% for Gram-positive S. aureus. AuNst conjugated hydrogel (AuNst120@H) reduced >80% colonies of P. aeruginosa and E. coli. In comparison, around 35.4% reduction of colonies are obtained for S. aureus. The viability assay confirmed the presence of about 85% of living NIH-3T3 cells when grown with hydrogels. An animal wound model is also developed to assess the efficiency of AuNst120@H. A significant reduction in wound size is observed on the 10th day in AuNst120@H treated animals with fully formed epidermal layers, hair follicles, new blood vessels, and arrector muscles. These findings suggest that novel dressing materials can be developed with antimicrobial nanotextured surfaces.

Prevalence and Predictors of Cervical Cancer Screening among Reproductive Age Group Women: Evidence from Cross-Sectional Study in Rohtak and Delhi.

BACKGROUND: The present study aims to estimate the prevalence and determine the factors for cervical cancer screening among women in the reproductive age group in Delhi and Rohtak, India. METHODS: The data were utilized from a survey conducted as part of a larger study to increase the access to cervical cancer screening and care by MAMTA-Health Institute for Mother and Child in collaboration with the Health Departments of Palam, New Delhi, and Rohtak, Haryana between 2015 and 2017. Data pertaining to the socio-economic and demographic information along with the information related to cervical cancer screening were utilized for the present study. The sample size was 1020 women in reproductive age group. Descriptive statistics (percentage and frequency distribution), bivariate analysis along with multivariable analysis were done to represent the results.  The Fisher exact test was used to test the level of significance during bivariate analysis. RESULTS: About 35.2% [Delhi: 44.9% and Rohtak: 23.8%] of the respondents had heard about cervical cancer screening. Further about 3.9% [Delhi-2.9% and Haryana-5.1%] had screened for cervical cancer. Women who had heard about cervical cancer were five times more likely to go for screening [aOR: 5.27; CI: 2.53,10.96]. It was found that women over 30 years of age had 12.04 significantly higher  odds of going for cervical cancer screening in reference to women aged 30 years and less [aOR: 12.04; CI: 3.01,53.20]. Women from households with a monthly income of more than 15000 had 2.98  significantly higher odds of going for cervical cancer screening in reference to women from households with an income of 5000 and less [aOR : 2.98; CI: 1.12,9.09]. CONCLUSION: Findings suggest that awareness about cervical cancer screening test along with its thorough knowledge about its benefits would be an effective intervention to increase the uptake of cervical cancer screening.
