Measurement of health system performance at district level: A study protocol
Background: Limited efforts have been observed in low and middle income countries to undertake health system performance assessment at district level. Absence of a comprehensive data collection tool and lack of a standardised single summary measure defining overall performance are some of the main problems. Present study has been undertaken to develop a summary composite health system performance index at district level. Methods: A broad range of indicators covering all six domains as per building block framework were finalized by an expert panel. The domains were classified into twenty sub-domains, with 70 input and process indicators to measure performance. Seven sub-domains for assessing health system outputs and outcomes were identified, with a total of 28 indicators. Districts in Haryana state from north India were selected for the study. Primary and secondary data will be collected from 378 health facilities, district and state health directorate headquarters. Indicators will be normalized, aggregated to generate composite performance index at district level. Domain specific scores will present the quality of individual building block domains in the public health system. Robustness of the results will be checked using sensitivity analysis. Expected impact for public health: The study presents a methodology for comprehensive assessment of all health system domains on basis of input, process, output and outcome indicators which has never been reported from India. Generation of this index will help identify policy and implementation areas of concern and point towards potential solutions. Results may also help understand relationships between individual building blocks and their sub-components
Validity of Palmar Pallor for Diagnosis of Anemia among Children Aged 6–59 Months in North India
Introduction. The Integrated Management of Childhood and Neonatal Illness (IMNCI) recommends the use palmar pallor to diagnose anaemia. Earlier studies to validate palmar pallor as clinical sign for anaemia were largely done in African context. There was a need to test validity of palmar pallor to detect anemia in different settings. Objective. To study the validity and interobserver agreement of palmar pallor examination to diagnose anemia in children under 5 years of age in India. Methods. In a village in Northern India, hemoglobin estimation was done for 80 children using cyanomethemoglobin method. Two examiners, a physician and a health worker, trained in IMNCI evaluated children for palmar pallor. Sensitivity and specificity and Kappa statistics were calculated. Results. Health worker diagnosed palmar pallor with sensitivity of 30.8–42.8% and specificity of 70–89%. Similar figures for doctor were 40–47% and 60–66%, respectively. Kappa agreement between a health worker and a physician was 0.48 (95% CI = 0.298–0.666) and then increased to 0.51 when categories of severe pallor and mild pallor were merged. Conclusion. While using palmar pallor as clinical sign for anaemia, children with no pallor should also be followed up closely for possible detection of missed cases during follow-up
The impact of alternate methodological and structural assumptions on results of cost-effectiveness analysis: empirical evidence using three Indian economic evaluations
Background: Despite advancement in methods and application of economic evaluations (EEs), there are several uncertainties.
Objectives: To assess the impact of alternate methodological and structural assumptions for four key principles of EE, on the results of cost-effectiveness analysis.
Materials and methods: Three previously published model-based EEs were used: (1) Integrated Management of Neonatal and Childhood Illnesses (IMNCIs) intervention; (2) intervention for multiple myeloma, and (3) safety-engineered syringes (SES) intervention. A series of empirical analyses was undertaken to assess the impact of alternate assumptions for discount-rate, time-horizon, study perspective, and health outcome measure, on incremental cost-effectiveness ratio (ICER), and interpretation of cost-effectiveness.
Results: Increasing discount rate resulted in an increase in ICERs, for all three case-studies; however, there was no change in the conclusions. Using shorter time-horizons resulted in a significant increase in ICERs, the multiple myeloma intervention remained cost-ineffective, SES intervention became cost-ineffective, whereas IMNCI intervention remained cost-effective, despite a three-fold increase in ICER. On using disability adjusted life years instead of quality adjusted life years, ICERs increased to 0.04, 2 and 4 times for SES, IMNCI and multiple myeloma interventions, respectively. On analyzing results from a societal perspective, a decline in ICERs was observed. The decline was significant for IMNCI where the intervention turned dominant/cost-saving. In the other two case-studies decline in ICERs was modest, 32% for multiple myeloma, and 4% for SES.
Conclusion: We observed a significant impact of using alternate assumptions on ICERs which can potentially impact resource-allocation decisions. Our findings provide strong argument in favor of standardization of processes and development of country-specific guidelines for conduct of EE

© 2024 The Author(s). Licensee MDPI, Basel, Switzerland. This is an open access article distributed under the terms of the Creative Commons Attribution License (CC BY), https://creativecommons.org/licenses/by/4.0/In response to the growing need for enhanced energy management in smart grids in sustainable smart cities, this study addresses the critical need for grid stability and efficient integration of renewable energy sources, utilizing advanced technologies like 6G IoT, AI, and blockchain. By deploying a suite of machine learning models like decision trees, XGBoost, support vector machines, and optimally tuned artificial neural networks, grid load fluctuations are predicted, especially during peak demand periods, to prevent overloads and ensure consistent power delivery. Additionally, long short-term memory recurrent neural networks analyze weather data to forecast solar energy production accurately, enabling better energy consumption planning. For microgrid management within individual buildings or clusters, deep Q reinforcement learning dynamically manages and optimizes photovoltaic energy usage, enhancing overall efficiency. The integration of a sophisticated visualization dashboard provides real-time updates and facilitates strategic planning by making complex data accessible. Lastly, the use of blockchain technology in verifying energy consumption readings and transactions promotes transparency and trust, which is crucial for the broader adoption of renewable resources. The combined approach not only stabilizes grid operations but also fosters the reliability and sustainability of energy systems, supporting a more robust adoption of renewable energies.Peer reviewe
Cost-effectiveness of therapeutic use of safety-engineered syringes in healthcare facilities in India
Background:
Globally, 16 billion injections are administered each year of which 95% are for curative care. India contributes 25–30% of the global injection load. Over 63% of these injections are reportedly unsafe or deemed unnecessary.
Objectives:
To assess the incremental cost per quality-adjusted life-year (QALY) gained with the introduction of safety-engineered syringes (SES) as compared to disposable syringes for therapeutic care in India.
Methods:
A decision tree was used to compute the volume of needle-stick injuries (NSIs) and reuse episodes among healthcare professionals and the patient population. Subsequently, three separate Markov models were used to compute lifetime costs and QALYs for individuals infected with hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). Three SES were evaluated—reuse prevention syringe (RUP), sharp injury prevention (SIP) syringe, and syringes with features of both RUP and SIP. A lifetime study horizon starting from a base year of 2017 was considered appropriate to cover all costs and consequences comprehensively. A systematic review was undertaken to assess the SES effects in terms of reduction in NSIs and reuse episodes. These were then modelled in terms of reduction in transmission of blood-borne infections, life-years and QALYs gained. Future costs and consequences were discounted at the rate of 3%. Incremental cost per QALY gained was computed to assess the cost-effectiveness. A probabilistic sensitivity analysis was undertaken to account for parameter uncertainties.
Results:
The introduction of RUP, SIP and RUP + SIP syringes in India is estimated to incur an incremental cost of Indian National Rupee (INR) 61,028 (US119,511) and INR 196,135 (US$3017) per QALY gained, respectively. A total of 96,296 HBV, 44,082 HCV and 5632 HIV deaths are estimated to be averted due to RUP in 20 years. RUP has an 84% probability to be cost-effective at a threshold of per capita gross domestic product (GDP). The RUP syringe can become cost saving at a unit price of INR 1.9. Similarly, SIP and RUP + SIP syringes can be cost-effective at a unit price of less than INR 1.2 and INR 5.9, respectively.
Conclusion:
RUP syringes are estimated to be cost-effective in the Indian context. SIP and RUP + SIP syringes are not cost-effective at the current unit prices. Efforts should be made to bring down the price of SES to improve its cost-effectiveness
Complementary feeding at 4 versus 6 months of age for preterm infants born at less than 34 weeks of gestation: a randomised, open-label, multicentre trial
Background Evidence on the optimal time to initiation of complementary feeding in preterm infants is scarce.
We examined the effect of initiation of complementary feeding at 4 months versus 6 months of corrected age on
weight for age at 12 months corrected age in preterm infants less than 34 weeks of gestation.
Methods In this open-label, randomised trial, we enrolled infants born at less than 34 weeks of gestation with no major
malformation from three public health facilities in India. Eligible infants were tracked from birth and randomly
assigned (1:1) at 4 months corrected age to receive complementary feeding at 4 months corrected age (4 month group), or
continuation of milk feeding and initiation of complementary feeding at 6 months corrected age (6 month group), using
computer generated randomisation schedule of variable block size, stratified by gestation (30 weeks or less, and
31–33 weeks). Iron supplementation was provided as standard. Participants and the implementation team could not be
masked to group assignment, but outcome assessors were masked. Primary outcome was weight for age Z-score at
12 months corrected age (WAZ12) based on WHO Multicentre Growth Reference Study growth standards. Analyses were
by intention to treat. The trial is registered with Clinical Trials Registry of India, number CTRI/2012/11/003149.
Findings Between March 20, 2013, and April 24, 2015, 403 infants were randomly assigned: 206 to receive
complementary feeding from 4 months and 197 to receive complementary feeding from 6 months. 22 infants in the
4 month group (four deaths, two withdrawals, 16 lost to follow-up) and eight infants in the 6 month group (two deaths,
six lost to follow-up) were excluded from analysis of primary outcome. There was no difference in WAZ12 between
two groups: –1·6 (SD 1·2) in the 4 month group versus –1·6 (SD 1·3) in the 6 month group (mean difference 0·005,
95% CI –0·24 to 0·25; p=0·965). There were more hospital admissions in the 4 month group compared with the
6 month group: 2·5 episodes per 100 infant-months in the 4 month group versus 1·4 episodes per 100 infant-months
in the 6 month group (incidence rate ratio 1·8, 95% CI 1·0–3·1, p=0·03). 34 (18%) of 188 infants in the 4 month
group required hospital admission, compared with 18 (9%) of 192 infants in the 6 month group.
Interpretation Although there was no evidence of effect for the primary endpoint of WAZ12, the higher rate of hospital
admission in the 4 month group suggests a recommendation to initiate complementary feeding at 6 months over
4 months of corrected age in infants less than 34 weeks of gestation

Type 1 diabetes, COVID-19 vaccines and short-term safety: Subgroup analysis from the global COVAD study
AIMS/INTRODUCTION
Coronavirus disease 2019 (COVID-19) vaccinations have been proven to be generally safe in healthy populations. However, the data on vaccine safety in patients with type 1 diabetes are scarce. This study aimed to evaluate the frequency and severity of short-term (<7-day) adverse vaccination events (AEs) and their risk factors among type 1 diabetes patients.
MATERIALS AND METHODS
This study analyzed data from the COVID-19 vaccination in Autoimmune Diseases (COVAD) survey database (May to December 2021; 110 collaborators, 94 countries), comparing <7-day COVID-19 vaccine AE among type 1 diabetes patients and healthy controls (HCs). Descriptive statistics; propensity score matching (1:4) using the variables age, sex and ethnicity; and multivariate analyses were carried out.
RESULTS
This study analyzed 5,480 completed survey responses. Of all responses, 5,408 were HCs, 72 were type 1 diabetes patients (43 females, 48.0% white European ancestry) and Pfizer was the most administered vaccine (39%). A total of 4,052 (73.9%) respondents had received two vaccine doses. Patients with type 1 diabetes had a comparable risk of injection site pain, minor and major vaccine AEs, as well as associated hospitalizations to HCs. However, type 1 diabetes patients had a higher risk of severe rashes (3% vs 0.4%, OR 8.0, 95% confidence interval 1.7-36), P = 0.007), although reassuringly, these were rare (n = 2 among type 1 diabetes patients).
CONCLUSIONS
COVID-19 vaccination was safe and well tolerated in patients with type 1 diabetes with similar AE profiles compared with HCs, although severe rashes were more common in type 1 diabetes patients
Tumor reversion: a dream or a reality.
Reversion of tumor to a normal differentiated cell once considered a dream is now at the brink of becoming a reality. Different layers of molecules/events such as microRNAs, transcription factors, alternative RNA splicing, post-transcriptional, post-translational modifications, availability of proteomics, genomics editing tools, and chemical biology approaches gave hope to manipulation of cancer cells reversion to a normal cell phenotype as evidences are subtle but definitive. Regardless of the advancement, there is a long way to go, as customized techniques are required to be fine-tuned with precision to attain more insights into tumor reversion. Tumor regression models using available genome-editing methods, followed by in vitro and in vivo proteomics profiling techniques show early evidence. This review summarizes tumor reversion developments, present issues, and unaddressed challenges that remained in the uncharted territory to modulate cellular machinery for tumor reversion towards therapeutic purposes successfully. Ongoing research reaffirms the potential promises of understanding the mechanism of tumor reversion and required refinement that is warranted in vitro and in vivo models of tumor reversion, and the potential translation of these into cancer therapy. Furthermore, therapeutic compounds were reported to induce phenotypic changes in cancer cells into normal cells, which will contribute in understanding the mechanism of tumor reversion. Altogether, the efforts collectively suggest that tumor reversion will likely reveal a new wave of therapeutic discoveries that will significantly impact clinical practice in cancer therapy
