Summary Acute encephalitis syndrome (AES) is a major public health challenge in India. We report here the epidemiology of sporadics and outbreaks of Japanese Encephalitis (JE) in Odisha state during 2012-2018. A total of 4235 AES cases (sporadics - 3394, outbreak cases - 841) recorded including 42 outbreaks; majority (n = 18) of which were during 2016. Overall JE virus (JEV) positivity was 11.78% (outbreak cases - 24.5%, sporadic cases - 8.6%). Age ≤15 years were largely affected during outbreaks, while 16-60 years population was dominant among sporadics. The major outbreak (2016) involved 336 patients from a tribal dominated district, spread over 173 villages. JEV seropositivity was high (43.45%) with 28.57% mortality. Epidemiological linkage with pig rearing was documented through JEV neutralizing antibodies in 50% of pig serum samples. Although the postvaccination period (2017-18) showed increase in AES case reporting but low JE proportion. Ongoing surveillance and preparedness of the health system would be of importance, especially in tribal-dominated districts.

Objectives: The objective is to study the clinico-epidemiological features of viral acute encephalitis syndrome (AES) cases and compare them with nonviral AES cases in children from Eastern India. Methods: This prospective observational study was conducted in the department of pediatrics of a tertiary care teaching hospital in Eastern India over 18-month period. Children (6 months to 15 years) with acute onset of fever (≥37.5°C) and a change in mental status (including symptoms such as confusion, disorientation, coma, or inability to talk) and/or new onset of seizures (excluding simple febrile seizures) were included in the study. The main outcome measures were the etiology and proportion attributed to viruses causing AES with clinical correlation. Results: Of 834 of clinically suspected AES cases, viral etiology could be confirmed in 136 (16.3%) cases (herpes simplex virus-1 [HSV-I] was most common). The 5-15 years' age group was most commonly affected (boys > girls). More cases occurred from July to November. The presence of rash and Glasgow Coma Scale <8 at admission was significantly higher in viral AES. During hospitalization, development of shock, ventilatory requirement, duration of stay, and mortality was significantly higher in viral AES. On neuroimaging, global cerebral injury was common in HSV, Japanese encephalitis, and varicella-virus AES. Conclusions: Viral etiology forms a significant proportion of pediatric AES. Morbidity and mortality are high in viral compared to nonviral AES. Herpes encephalitis (HSV-I) is the most common cause of pediatric AES in Eastern India. Viral AES has poor prognosis compared to nonviral AES.

HPV is the major causative agent for cervical cancer. Study on the risk of cervical cancer associated with different hr-HPV genotypes would be useful for disease management and new vaccine strategy. With limited reports available, the present study aimed to investigate the pattern of HPV genotypes coinfections and risk of cervical carcinoma associated with them in Indian population. 15 HPV genotypes were detected by E6/E7 multiplex nested type-specific PCR in the HPV-positive cervical samples of 172 cervical cancer cases and 174 subjects with normal cytology. Association between the genotypes and cervical cancer was estimated by calculating the Odds ratio and 95% confidence interval. Risk of cervical carcinoma was associated with multiple genotypes excluding HPV16 (OR:5.87; 95% CI-1.28-26-29; p = .02), multiple genotypes excluding HPV18 (OR = 2.5; 95% CI = 1.09-6.05; p = .03), multiple genotypes of α9 species(OR = 5.3 95% CI = 1.14-24.03; p = .007), and multiple genotypes of α7 species (OR = 2.5; 95% CI = .49-13.45; p = .2). Genotypes not targeted by quadrivalent vaccine types (OR = 2.94 95% CI = 1.48-5.80; p = .001) conferred 2.94 fold higher risk of cervical carcinoma. Cases those coinfected with phylogenetically related genotypes (OR = 2.29; 95% CI(.69-7.59) p = .17) were at 2.9 fold higher risk of invasive cervical carcinoma than those infected with other genotypes although it is not statistically significant. Whereas phylogenetically unrelated genotypes coinfection is negatively associated with cervical carcinoma (OR = .44 95% CI (.244-.8) p = .007) and it is statistically significant.Genotypes not targeted by 9-valent vaccines (OR = .40; 95% CI = .19-.85; p = .017) associated with lesser risk of cervical carcinoma as compared to other genotypes. Subjects infected with any HPV genotype/genotypes excluding HPV16 in association with HPV 18 (OR = 4.1; 95% CI = 1.81-9.25 P = < .001) were at 4.1 fold higher risk of developing invasive cervical carcinoma.In conclusion, the risk of development of cervical cancer is genotype specific and might be associated with type-specific interactions between the genotypes in multiple infections.

Human Papillomavirus is the major etiological agent in the development of cervical cancer but not a sufficient cause. Despite significant research, the underlying mechanisms of progression from a low-grade squamous intraepithelial lesion to high grade squamous intraepithelial lesion are yet to be understood. Deregulation of viral gene expression and host genomic instability play a central role in virus-mediated carcinogenesis. Key events such as viral integration and epigenetic modifications may lead to the deregulation of viral and host gene expression. This review has summarized the available literature to describe the possible mechanism and role of viral integration in mediating carcinogenesis. HPV integration begins with DNA damage or double strand break induced either by oxidative stress or HPV proteins and the subsequent steps are driven by the DNA damage responses. Inflammation and oxidative stress could be considered as cofactors in stimulating viral integration and deregulation of cellular and viral oncogenes during the progression of cervical carcinoma. All these events together with the host and viral genetic and epigenetic modifications in neoplastic progression have also been reviewed which may be relevant in identifying a new preventive therapeutic strategy. In the absence of therapeutic intervention for HPV-infected individuals, future research focus should be directed towards preventing and reversing of HPV integration. DNA damage response, knocking out integrated HPV sequences, siRNA approach, modulating the selection mechanism of cells harboring integrated genomes and epigenetic modifiers are the possible therapeutic targets.

The transition from hospital to home for children and their caregivers has been understudied, particularly in the context of children with complex illnesses. This pilot study aimed to explore caregivers’ and nurses’ perceptions of unmet needs during this transition and to make recommendations for future research. In this qualitative study, data were collected through separately conducted focused group discussions with caregivers ( n  = 6) and nurses ( n  = 6). The discussions were facilitated by an experienced qualitative researcher, ensuring an unbiased approach. Emergent themes were categorized into four areas: (1) Insufficient Caregiver Involvement in Child Care (2) Knowledge Gaps Hindering Effective Post-Transition Care (3) Barriers to Accessing Community Health Resources, and (4) Evolving Perspectives on Transition Care. Findings suggest significant opportunities to enhance paediatric transition care practices and better prepare caregivers to shift from hospital to home. Thematic analysis, following Braun and Clarke’s (2006) framework, was used to analyze the data.

The purpose of this study was to compare the efficacy of oral triclofos (TRI), intranasal midazolam (INM), and intranasal dexmedetomidine (IND) in achieving successful sedation in children undergoing MRI. This open-label, three-arm, randomized trial was conducted in a tertiary care teaching hospital over 18-month period. Children scheduled for MRI were enrolled. Rate of successful/adequate sedation was assessed using the Paediatric Sedation State Scale (PSSS). The primary outcome was the efficacy (successful sedation or sedation rate) of the three drugs. One-hundred and ninety-five children were included for the MRI procedure. IND was found to be superior in terms of achieving successful sedation. INM had a shorter onset and duration of sedation compared to IND and TRI, but with an increased failure rate (88.3%). Keeping INM as the reference group, it was found that the odds of sedation increased 4.1 times on changing from INM to IND ( p  < 0.01), and 2.26 times on changing from INM to TRI ( p  < 0.01). Adverse events included nasal discomfort (18.3%) in INM group; and self-limited tachycardia (4.6%) and hypotension (10.8%) in the IND group. Conclusion : IND was more efficacious than INM or TRI for procedural sedation in children undergoing MRI without any significant adverse events. Clinical trial registration : CTRI/2019/01/017257; date registered: 25/01/2019. What is Known: • Oral triclofos (TRI) and intranasal midazolam (INM) have been used for procedural sedation in children undergoing MRI with variable success; but the experience with intranasal dexmedetomidine (IND) is limited. What is New: • IND provides more effective sedation compared to INM or TRI for procedural sedation in children undergoing MRI, without any significant adverse events.

Background Caregivers of children with congenital heart disease (CHD) often experience stress, uncertainty, and challenges in managing their child's care after hospital discharge. A structured transition care approach can help ease this process by improving caregivers' preparedness, awareness, and satisfaction with post-discharge care. Objective This study aims to develop and evaluate a nurse-led transition care guidance (TCG) program to enhance caregivers' readiness, awareness, and satisfaction during the transition from hospital to home care for children with CHD. Method A mixed-methods approach was used, consisting of a quasi-experimental quantitative phase to assess the effectiveness of the TCG intervention by comparing caregivers' readiness and satisfaction scores before and after implementation and qualitative focus group discussions (FGDs) to explore caregivers' unmet needs and challenges during the transition process. Data sources include caregiver surveys, post-discharge follow-up interviews, and hospital records. Thematic analysis will be conducted on FGDs to identify key issues affecting caregivers. Results The intervention is expected to improve caregivers' ability to provide care, increase their understanding of medical needs, and enhance their overall satisfaction with the transition process. Qualitative findings will highlight common challenges and gaps in post-discharge support. Conclusion This study will contribute to the development of evidence-based transition care plans that optimize the hospital-to-home transition for children with CHD. It highlights the importance of structured, nurse-led interventions to improve post-discharge outcomes for both caregivers and patients.

Background Tribal populations constitute a major portion of India's total population, especially in the eastern and northeastern states. We lack comprehensive information on the community burden of general morbidity and febrile illness in tribal population-dominated areas, which is quite essential for the microplanning of healthcare expenditure and implementation. This study aimed to provide evidence on the prevalence and pattern of general morbidity and febrile illness at the community level as well as the treatment-seeking behaviour in a tribal-dominated area. Methods The study was undertaken as an observational study in the community setting; looking into seasonal cross-sectional evidence on period prevalence (two weeks) of morbidity and qualitative/semiquantitative information on treatment-seeking behaviour of the selected community during 2012 and 2013. Result This study involved 5541, 5482, and 5638 individuals during the rainy season 2012, winter 2012-13, and rainy season 2013 seasons, respectively, from 25 tribal villages of Odisha, India. A period prevalence (two weeks) of overall morbidities was shown to be 27.28% and 28.9% during the rainy seasons of 2012 and 2013, respectively, of which 13% and 11.5%, respectively, were febrile, with low prevalence (6.44% overall morbidity and 1.81% febrile illness) in the winter of 2012-13. It indicated inadequacy in skills of the village-level health staff, monitoring of supplies/logistics, and population awareness for early reporting of fever to healthcare providers at the community level. Conclusion The evidence provided by the study would be helpful in making public health plans in tribal settings and also highlighted the opportunity to improve tribal health status through community awareness, especially in areas and populations with limited health access.

The persistence of residual infection is one of the major factors in failure of the Global Programme to Eliminate Lymphatic Filariasis (GPELF). The present study aims to explore the status of sheath antibody and regulatory T cells (Tregs) known to play key roles in clearance of parasite and patent filarial infection, in individuals with residual infection after MDA. A total of 61 microfilaremic (Mf) individuals were followed up after at least 6 rounds of MDA. Infection status of subjects was assessed through the detection of Mf and circulating filarial antigen (CFA). Antibodies to Mf sheath were determined by immuno-peroxidase assay (IPA). The expression of Tregs was measured by a flow cytometer. IL-10 and IFN-γ were evaluated using the commercially available ELISA kit. The sheath antibody was present in subjects who have cleared both Mf and CFA and absent in individuals who were found to be Mf /CFA positive. Further individuals carrying infection have significantly high levels of Tregs and IL-10. A positive correlation was observed between Tregs, IL-10, and CFA in infected individuals. In contrast, a negative correlation was observed between IFN-γ and IL-10 in both infected and uninfected subjects. Our study reveals that the absence of a sheath antibody and a high level of Tregs and IL-10 are the hallmarks of the persistence of residual filarial infection.
