Charting the Course: Towards a Comprehensive Newborn Screening Program in India.

Integrating health interventions in a growing economy like India, with a birth cohort of 27 million/year, one-fifth of all childbirths, and approximately one-third of neonatal deaths globally, is a challenge. While mortality statistics are vital, intact survival and early preventive healthcare, such as newborn screening (NBS), are paramount. The appalling lack of information about the precise burden of metabolic errors at the state/national level or a mandated program encouraged a feasibility study of NBS in a prospective newborn cohort recruited in Delhi State (November 2014-April 2017) using a public-private partnership mode. The major determinants for effective implementation of universal NBS at the national level and limitations encountered are discussed in this report. Data to generate the 'core' panel for screening, sustained training of healthcare personnel, dissemination of the power of NBS to ensure neonatal/societal health to the public, and a 'national policy' emerge as priorities in a developing country.

Sildenafil as a Candidate Drug for Alzheimer's Disease: Real-World Patient Data Observation and Mechanistic Observations from Patient-Induced Pluripotent Stem Cell-Derived Neurons.

Background: Alzheimer's disease (AD) is a chronic neurodegenerative disease needing effective therapeutics urgently. Sildenafil, one of the approved phosphodiesterase-5 inhibitors, has been implicated as having potential effect in AD. Objective: To investigate the potential therapeutic benefit of sildenafil on AD. Methods: We performed real-world patient data analysis using the MarketScan® Medicare Supplemental and the Clinformatics® databases. We conducted propensity score-stratified analyses after adjusting confounding factors (i.e., sex, age, race, and comorbidities). We used both familial and sporadic AD patient induced pluripotent stem cells (iPSC) derived neurons to evaluate the sildenafil's mechanism-of-action. Results: We showed that sildenafil usage is associated with reduced likelihood of AD across four new drug compactor cohorts, including bumetanide, furosemide, spironolactone, and nifedipine. For instance, sildenafil usage is associated with a 54% reduced incidence of AD in MarketScan® (hazard ratio [HR] = 0.46, 95% CI 0.32- 0.66) and a 30% reduced prevalence of AD in Clinformatics® (HR = 0.70, 95% CI 0.49- 1.00) compared to spironolactone. We found that sildenafil treatment reduced tau hyperphosphorylation (pTau181 and pTau205) in a dose-dependent manner in both familial and sporadic AD patient iPSC-derived neurons. RNA-sequencing data analysis of sildenafil-treated AD patient iPSC-derived neurons reveals that sildenafil specifically target AD related genes and pathobiological pathways, mechanistically supporting the beneficial effect of sildenafil in AD. Conclusions: These real-world patient data validation and mechanistic observations from patient iPSC-derived neurons further suggested that sildenafil is a potential repurposable drug for AD. Yet, randomized clinical trials are warranted to validate the causal treatment effects of sildenafil in AD.

Dentofacial manifestations in a child with Jalili syndrome.

Jalili syndrome (JS) (MIM#217080) is a rare autosomal recessive disorder with oculo-dental malformations. The clinical phenotype is characterized by the presence of Cone-Rod Dystrophy (CRD) and Amelogenesis Imperfecta (AI). Genetic mechanism entails a mutation in the CNNM4, a metal transporter gene located on Chromosome 2q11.2. A high fluoride concentration in groundwater has also been identified as an epigenetic factor in this syndrome. JS draws the attention of dentists due to its distinct oral manifestations. To the best of our knowledge, this is the first genetically confirmed pediatric case report from the Indian subcontinent emphasizing the clinical and radiographic features of this condition and its management in a 6-year-old child.

Environment Practices Mediating the Environmental Compliance and firm Performance: An Institutional Theory Perspective from Emerging Economies.

Coercive pressure has forced firms to take up environmental measures in the last two decades in emerging economies. Under normative pressure, large firms with farsightedness take up the environmental practices as industry leaders. In a little mature emerging economy, such as India, where triple bottom line awareness is growing, the government facilitates the firms to operate in an environment-friendly ecosystem. We investigate how do environmental compliance and environmental practices influence the overall firm performance? The performance was measured in terms of financial, customer, internal business process, and learning and growth performance. A survey instrument was designed using well-established scales and administered to the middle to top-level corporate management executives to gather 240 data from the Indian firms. A rigorous statistical validity, diagnostics, and SEM were used to test the hypotheses. The environmental practices showed a full mediation effect on the effect of environmental compliance on performance. The examination of mediation relationships in an environmental context is limited in the reported literature. This paper is among the initial works that deal with complicated mediation relationships drawn from institutional theory propositions. The study established and argued that environmental practices' ecosystem would turn firms towards voluntary environmental compliance and eventually enjoy the long-term performance.
