    Abstract Introduction: Transformational advances have occurred in the management of haemophilia in the last decade leading to much better outcomes. However, a detailed and critical examination of its assessment and reporting show gaps in many aspects. These are discussed in this review.
    Methods: The relevant literature related to different aspects of management of haemophilia was reviewed to identify gaps which need to be addressed. These include detection and diagnosis of haemophilia, documentation and reporting of joint bleeding, its management and methods of reporting in clinical trials and practice, aspects of personalizing care as well as access to therapeutic products and the need for and organization of comprehensive care.
    Results: Current diagnostic approaches have more than doubled the identified number of persons with haemophilia (PWH) over the last 25 years but still constitute only ∼30% of the expected number. Joint bleeding is the primary indicator of disease severity and treatment efficacy, but there is lack of consistency and standardization in the way it is recorded and reported. Its continued use as an efficacy measure of modern treatments which maintain steady state factor levels or equivalence of >5% will lack sensitivity. The treatment of acute haemarthrosis has focussed on haemostasis and pain control, ignoring the role of inflammation in joint damage. Phenotypic heterogeneity of severe haemophilia has recognized clinical and laboratory variations based on haemostasis but not differences in local response to blood in the joint. At the organizational level, IU/capita provides a relevant measure of access to therapeutic products when the detection rate is ∼100% but is fallaciously low when detection rates are very low. With highly effective modern therapies for haemophilia and nearly no bleeding, the concept of comprehensive care team will need modifications.
    Conclusion: As haemophilia care advances, a deeper dive is needed into the details of various aspects its management to ensure consistency and contemporary relevance.

    Abstract COVID-19 pandemic has affected every country across different continents, be a developed or developing economy. The COVID-19 pandemic has led to a dramatic loss of human life worldwide and presents an unprecedented challenge to public health, food systems and the world of work. Conducting evaluation during COVID-19 pandemic was even more challenging as compared to the evaluation in conflict areas. Sudden lockdown and sustained restrictions was unexpected and affected the evaluators plan of actions for the ongoing as well as forthcoming evaluation activities. Not only primary data collection but secondary research also got hampered as access to knowledge resource centres/libraries stopped due to closure of these centres. As far as primary data collection is concerned, not only data collection exercise got stopped but even for those evaluations where data collection had been completed, the electronic data entry of filled-in survey schedules got stalled for a while. The paper discusses the critical components of evaluation, which gets affected during pandemic like situation such as use of participatory evaluation techniques; missing evidence based policy decisions; external and internal validity not ensured or ethical norms get compromised. To overcome such situations, the evaluation world should be ready with the suggested solutions such as, Use of Artificial Intelligence, computer-assisted interviews, capacity building of community members for participatory evaluation and making ethical review of evaluation protocols mandatory.

    Abstract The current paradigm for the diagnosis of haemophilia and other inherited bleeding disorders (IBDs) based on clinical assessment followed by screening tests and confirmation by assays of clotting factor levels or platelet functions is complex and cumbersome. These have been difficult to establish and standardize around the world for many reasons. Therefore, more than half of the expected number of people with these disorders in the world remain unidentified. A new approach is therefore needed. Use of validated bleeding assessment tools (BATs) offers an opportunity for standardized evaluation of clinically significant bleeding at the primary care level or even to be self-assessed. Advances in genetic evaluation of these disorders through gene panels covering a wide range of IBDs based on next generation sequencing (NGS) technology enable the identification of the primary defect in the haemostasis system with high degree of accuracy. These methods can be centralized and made highly cost-effective when done in large batches. The combination of high BAT score followed by NGS-based genetic diagnosis could be the new paradigm for the primary diagnosis of IBDs. This will need to be followed by confirmation with functional haemostasis tests, as required. This approach will increase rates of detection of the known common disorders many folds and reduce the burden on these families towards accessing facilities for accurate diagnosis and appropriate treatment based on that.

    Abstract A set of 17 Sustainable Development Goals (SDGs) adopted by the United Nations General Assembly in September 2015 are to be implemented and achieved in every country from the year 2016 to 2030. In Indian context, all these goals are very relevant and critical, as India missed the target on many components of the Millennium Development Goals (MDGs). The author strongly feels that one of the key reasons was lack of an in-built robust system for measuring the progress and achievements of MDGs. Monitoring and Evaluation of programmes and schemes, aiming at different SDGs, in a robust and regular manner is therefore need of the hour. A National evaluation policy (NEP) would set the tone in the right direction from the very beginning for achieving SDGs. The paper taking India as a case study discusses different critical factors pertinent for having a well laid down national level policy towards standardizing evaluation. Using real examples under different components of an evaluation policy, the paper discusses and questions the credibility and acceptance of the present evaluation system in place. The paper identifies five core mantras or pre-requisites of a national evaluation guideline. The paper emphasizes the importance of an evaluation policy in India and other countries as well, to provide authentic data gathered through a well-designed evaluation process and take corrective measures well on time to achieve SDGs.

    Abstract: Curvularia leaf spot affects maize plants worldwide and is commonly caused by Curvularia lunata, C. geniculata, and C. pallescens (Manzar et al. 2022; Manzar et al. 2021; Choudhary et al. 2011). In February 2017, leaf spot symptoms were observed in a ... ...

    Abstract Curvularia leaf spot affects maize plants worldwide and is commonly caused by Curvularia lunata, C. geniculata, and C. pallescens (Manzar et al. 2022; Manzar et al. 2021; Choudhary et al. 2011). In February 2017, leaf spot symptoms were observed in a Deogaon, (25.74 N, 82.99 E) in Uttar Pradesh, India, with disease incidence of less than 10% of the plants in maize fields. On the leaves and sheaths, variously shaped yellow spots were developed. The spots were 2.5 mm in diameter and frequently grew larger, reaching a diameter of 1 cm. They were encircled by a chlorotic halo with dark borders. The symptomatic tissue showing leaf spots of 10 plants was taken and cut into pieces (4 mm2) then surface sterilized with 1% sodium hypochlorite for 1 min, and rinsed three times with distilled water. The cut leaf tissue was placed on the Petri plate containing potato dextrose agar medium amended with streptomycin sulfate (125 ppm). Then incubated at 25±2°C with a 12-h light and dark period, after 5 days of incubation, five pure cultures were obtained using the hyphal tip technique. The pure culture was incubated at 26±2°C for 10 days. The upper surface of the colony was dark grayish black with fluffy mycelia, and the reverse colony was dark brown. The conidia have three septa, are light brown to dark brown in color, straight to curved, ellipsoidal to fusiform, and have two bigger, darker central cells than terminal cells. On average, conidia are between 27.22 to 31.21 mm long and 10.61 to 12.62 mm wide (n=30). The morphological description is similar to the Curvularia verruculosa morphological traits described by Tandon & Bilgrami (Ellis 1966). Molecular identification was done in addition to supporting morphological identification. The nucleopore GDNA Fungus Kit (Genetix Brand, India) was used to extract the genomic DNA of the E40 isolate. The ITS rDNA region (White et al. 1990) and the glyceraldehyde-3-phosphate dehydrogenase (gpd) gene (Berbee et al. 1999) were amplified through PCR(Manzar et al., 2022).The amplicons were bidirectional sequenced through the Sanger sequencing method. The similarity percentage of E40 isolate matched 100% with MH859788 (CBS444.70 ) of Curvularia verruculosa strain for ITS, and 100% with LT715824 (CBS150.63) of Curvularia verruculosa strain for gpd after Blastn analysis. The gene sequences were deposited to GenBank and accession no. OR262893 for ITS, and LC773704 for gpd were assigned. As a result, C. verruculosa was determined to be the presumed pathogen by both morphology and molecular characteristics. The pathogenicity of E40 isolate was performed twice by spraying (106 conidia/ml in sterile water) onto the leaves of 25 days old maize plant cv. Kanchan (n = 10). Uninoculated healthy maize plants (n=5) were sprayed only with autoclaved water. All pots are kept in a glass house at 25°C±2°C with 90% relative humidity. After 15 days of pathogen inoculation the foliar spots with chlorotic halo, enlarger upto 1cm, and from these spots the identical fungus was reisolated. The reisolated fungus showed similar morphological characteristics to C. verruculosa. Control plants showed no symptoms. C. verruculosa has been previously reported as a causative agent of leaf spot disease in Common beans (Wei et al., 2022), Cotton (Shirsath et al., 2018). To our knowledge, this is the first report of leaf blight caused by C. verruculosa on maize in India.

    Abstract For the medical diagnosis, radiopaque materials (RM) made from high specific gravity elements like Pt, Au, Ta, Iodine, Bromine are either attached or blended or coated on an implant to makes it detectable under X-ray/Fluoroscopy/CT-Scan. RM facilitate the surgeon in an operation theatre to position an implant during the surgery. Mainly, RM are non-degradable, thus in case of biodegradable implants, it may detach from the body and accumulate in vital organ cause serious health issue. Therefore, a new bioresorbable radiopaque material (BRM) was produced by alloying the high specific gravity elements Zn (35% w/w) and Y(4% w/w) with Mg metal. In this alloy, three main phases were identified, alpha Mg, Mg₇Zn₃ and icosahedral quasicrystalline I-phase Mg₃Zn₆Y, which reinforce the Mg matrix. Hereafter, BRM was powdered to a size of less than 25 microns and blended in different ratios with bioresorbable poly-L-lactic acid (PLLA) for fabricating PLLA/BRM bio-composite. BRM microparticles were uniformly distributed and interfacial bonded with the matrix. The X-ray was passed through bio-composite to capture µCT radiograph for evaluating linear attenuation co-efficient (µ) and optical density (OD). Thermal analysis reveals that BRM particles act as a nucleating site and enhance the crystallinity of the polymeric chain. During the In Vitro accelerated degradation study, the alkaline nature of BRM neutralise the acidity of PLLA and balance the pH of the body fluid to reduce the inflammatory reactions, but this compromises the stability of the polymer as it increases the decomposition rate.
