In this paper, we obtain a converse duality theorem for higher order Wolfe type multiobjective programming with cone constraints under appropriate assumptions. This fills some gaps in the work of Kim et al. [Kim, D.S., Kang, H.S., Lee, Y.J., Seo, Y.Y., Higher order duality in multiobjective programming with cone constraints, Optimization, 59(1), 29–43, (2010)].

ABSTRACT: Purpose: The aim was to analyse the knowledge and awareness regarding Ayushman Bharat – Pradhan Mantri Jan Arogya Yojana (AB-PMJAY) within the operational districts of two high-volume non-profit eye organisations in Uttar Pradesh. Challenges faced by beneficiaries and non-beneficiaries are also examined. Methods: A prospective cross-sectional survey from November 2021 to April 2022 was conducted across operational districts of organisations A and B. Cluster sampling was used to select participants in randomly selected villages with 200 or more households, within 10–15 km of existing vision centres. A semi-structured interview schedule was used to collect data. The means of AB-PMJAY indicators were estimated. Awareness was estimated as a summed score. Multivariate logistic regression was applied to check the effects of the socio-economic and socio-demographic factors on the awareness of AB-PMJAY for both organisations separately and together. Results: A total of 1151 participants were interviewed: 52.9% from the catchment area of organisation A and 47.1% from that of organisation B. From the catchment of organisations A and B, 82.6% and 22.9% participants, respectively, had heard of the scheme, mostly from family and friends. Whereas 43% interviewees from the catchment area of organisation A and 8.5% from that of organisation B had knowledge about at least one topic, only 8.5% and 2.8%, respectively, were knowledgeable about all topics. Village effect was found to be significant for most of the knowledge and awareness indicators in both catchments. Only 37.8% and 20.2% of the catchment from organisations A and B, respectively, were AB-PMJAY cardholders. Of the services availed, 50% were cataract surgery. Almost 40% of the applicants faced some challenges while securing the AB-PMJAY card and 9% while using the AB-PMJAY card. Family income was found to be the only common predictor of knowledge at both locations. Conclusion: Varied awareness and limited knowledge in catchment villages put the onus on community eyecare organisations to spread awareness in their catchment, which may increase the uptake and utilisation of the scheme.

Background: Noncultured epidermal cell suspension (NCES) and Jodhpur technique (JT) are two treatment options in vitiligo, in which the basic principle is the transfer of melanocytes from uninvolved skin to stable vitiligo patch in the form of either tissue graft or cellular graft. Objectives: The aim of this study was to evaluate effectiveness of two different treatment methods (NCES and JT) in stable vitiligo. Materials and Methods: This was a randomized comparative study, which included 45 patients with 153 stable vitiligo patches. Cases were randomly divided into two groups. Appropriate statistical analysis was done. A value of P < 0.05 was considered statistically significant. Results: Of 45 cases, female-to-male ratio was 1.36:1. Mean duration of disease and stability were found to be 10.44±5.24 and 3.83±2.31 years, respectively. Mean size of treated area for NCES and JT was 10.11±10.31 and 10.13±10.29cm2, respectively. Earliest repigmentation was found at 3 weeks in NCES and 6 weeks in JT. At 6 weeks, repigmentation was better in NCES, whereas later JT showed better pigmentation. Follow-up was done at 8 days and 6, 10, 14, and 24 weeks. With respect to color match at 6 weeks, JT was found superior; however, at 24 weeks both showed similar efficacy. Mean reduction in daily life quality index was significantly decreased post-surgery. Limitations: This was a single-center, small sample size study. Conclusion: Melanocyte plus keratinocyte cell transfer is very effective in the treatment of stable vitiligo. On the basis of the results, JT may show significant contribution in vitiligo.

Although a great deal of work has been done on bi-level programming problems (BPPs) during the last few decades, there is still a substantial gap in the literature on sufficient optimality conditions and duality results of BPPs. This article aims to develop sufficient optimality conditions and Mond-Weir-type dual for a multi-objective BPP from an optimistic perspective under the Guignard constraint qualification. Using the weighted sum scalarisation at the lower level and a special function at the upper level, we convert the multi-objective BPP to the corresponding single-objective BPP. With the help of optimal value reformulation, we reformulate the single-objective BPP as a single-level mathematical programming problem. Using the generalised convexity, we develop sufficient optimality conditions. Moreover, we formulate Mond-Weir type dual and establish the corresponding duality results. [ABSTRACT FROM AUTHOR]

There are several classes of decision-making problems that explicitly or implicitly prompt fractional programming problems. Portfolio selection problems, agricultural planning, information transfer, numerical analysis of stochastic processes, and resource allocation problems are just a few examples. The huge number of applications of minimax fractional programming problems inspired us to work on this topic. This paper is concerned with a nondifferentiable minimax fractional programming problem. We study a parametric dual model, corresponding to the primal problem, and derive the sufficient optimality condition for an optimal solution to the considered problem. Further, we obtain the various duality results under (p, r)-ρ-(η, θ)-invexity assumptions. Also, we identify a function lying exclusively in the class of (−1, 1)-ρ-(η, θ)-invex functions but not in the class of (1, −1)-invex functions and convex function already existing in the literature. We have given a non-trivial model of nondifferentiable minimax problem and obtained its optimal solution using optimality results derived in this paper. [ABSTRACT FROM AUTHOR]

Preterm babies have immature immunity and skin barrier functions. To cope up with these, many times they are kept under observation in neonatal care unit (NICU) for months until they attain their normal physiological age, weight, and immune functions along with other vital capacities. We are reporting such a curious case of 1-month-old preterm child who presented with the sequence of blackish blue to yellowish discoloration of thumb nails in both the hands. [ABSTRACT FROM AUTHOR]

Background: Surgical treatment of vitiligo is reserved for stable recalcitrant vitiligo patches. Split-thickness skin grafting (STSG) is an important established modality for the surgical treatment of vitiligo, whereas autologous, non-cultured, non-trypsinized epidermal cell transplant, also known as Jodhpur technique (JT), is an unconventional innovative surgical modality for the treatment of stable vitiligo. Aims: To compare the two techniques, JT and STSG, with regards to the extent and pattern of repigmentation achieved, color matching of the repigmented area, patient satisfaction (Dermatology Life Quality Index [DLQI] questionnaire and patient global assessment), and adverse events (if any) in patients with stable vitiligo. Materials and Methods: It was a randomized comparative study. We randomized 32 patients with 180 stable vitiligo lesions into two groups. Patients in group 1 were treated with JT, and those in group 2 with STSG. They were subjectively evaluated 20 weeks post-surgery for the extent of repigmentation, color match, change in DLQI score, and patient satisfaction. The categorical data were presented as number (percent) and were compared among groups using Chi-square test. Mean and standard deviation were calculated for demographic data, and they were also compared by using student t-test. Probability P value < 0.001 was considered statistically significant. Results: The extent of repigmentation was excellent (90%--100% repigmentation) in 72.5% of lesions in the JT group and in 40% of lesions in the STSG group (P < 0.001). Seventy-five percent repigmentation (good repigmentation) was observed in 95% of lesions in the JT group and in 83.75% of lesions in the STSG group (P = 0.040). There was a highly significant decline in DLQI score. Post-procedure DLQI (0.79 ± 1.13) and pre-procedure DLQI (15.39 ± 4.76) in the JT group were compared with post-procedure DLQI (3.85 ± 2.89) and pre-procedure DLQI (16.19 ± 4.56) in the STSG group. The mean decline among groups differed significantly (P < 0.001). Adverse events were significantly higher in the STSG group at the recipient site. Conclusions: JT is found to be significantly better than STSG with regard to the degree of repigmentation. [ABSTRACT FROM AUTHOR]

Background: Parthenium dermatitis is caused by friable plant extracts of Parthenium hysterophorus and related species. Approximately 40% of cases of plant dermatitis in India are contributed by this single species. Materials and Methods: This was a cross-sectional, observational study conducted in the Department of Dermatology of Jhalawar Medical College. Ninety-nine consecutive patch test positive parthenium dermatitis human subjects of age more than 16 and either sex were included. The study period was 11 months between September 2019 and August 2020. Sociodemographic, clinical profile parthenium dermatitis severity score (PDSS) and Dermatology life quality index (DLQI) were obtained from each patient. Correlation between PDSS and DLQI was obtained using Pearson's two-tailed coefficients. Results: Our study included 62 men and 37 women (1.67:1). The mean age was 51 ± 10.27 years. Mean duration of disease was 8.47 ± 4.45 years, and mean PDSS was 57.25 ± 17.65, mean DLQI was 17.14 ± 5.56. ABCD with CAD was the most common clinical subtype (45.45%). A significant positive correlation was observed between PDSS and DLQI. Conclusion: In this study, a significant impairment in quality of life (QoL) was observed in patients with higher score of PDSS and increasing duration, emphasizing that the disease needs specialized care including multiple indoor admission at the time of flare-up of disease.

The thermoelectric properties of a series of the polycrystalline samples of titanium dichalcogenides with partial substitution of Ti for Nb and S for Se were investigated. It was found that sintering of the samples improved the thermoelectric efficiency (ZT), and the maximum ZT was achieved at sintering temperature of 600°C. A further increase in the sintering temperature (850°C and 950°C) led to the recrystallization of the samples, as a result, the Seebeck coefficient sharply decreased and electrical conductivity dramatically increased. The temperature dependences of electrical conductivity σ(T) in the temperature range from 4.2 to 300 K and Seebeck coefficient S(T) in the temperature range from 77 to 300 K were investigated in order to determine the nature of the observed improvements in thermoelectric properties due to double substitutions and sintering. Two‐dimensionalization of electron transport properties of Ti1−xNbxS2−ySey solid solutions was found. The Fermi energy EF2D was estimated using the temperature dependences of Seebeck coefficient. The relationship between the Fermi energy EF2D and figure of merit ZT was established. The effect of sintering on parameters σ(T), S(T), charge carrier concentration (n2D), mobility (µ), and thermal conductivity (k) was found. The optimal value of Fermi energy EF2D in terms of figure of merit ZT = 0.31 at room temperature (T = 300 K) was found for Ti0.98Nb0.02S1.3Se0.7 sample sintered at 600°C. [ABSTRACT FROM AUTHOR]

Background: Pediatric dermatoses present as one of the most common clinical entities in dermatology clinics. They differ in clinical presentation and management from adults. Their prevalence and pattern differ from region to region due to several factors such as environmental, social, genetic, and cultural. Aims and Objective: The aim of the study was to determine the prevalence and pattern of various dermatoses among children of the age group 0–18 years in Southeast region of Rajasthan. Materials and Methods: Our study included 1000 cases of 0–18 years age group attending the dermatology outpatient and inpatient department of Government Medical College and attached group of hospitals, Kota. It was carried out from December 2017 to September 2018 (10 months). Appropriate history was taken, and a complete thorough examination was done as required. Relevant investigations were done, and all the findings were recorded in predesigned pro forma. Results: Our study included 560 males and 440 females of 1000 with the male-to-female ratio of 1.272:1. There were 553 urban and 447 rural participants. The patients were subgrouped in the age group of 0–1 year, 1–7 years, 8–12 years, and 13–18 years. The most prevalent dermatoses in 0–1 year age group were eczematous disorders (31.91%). Viral infections were predominant in 26.08% and 23.47% in the age groups of 1–7 years and 8–12 years, respectively. The most common dermatoses in the age group of 13–18 years were disorders of sweat and sebaceous glands (20.15%). Conclusion: Our study demonstrates variability of dermatoses among pediatric patients according to their age groups. This information should contribute to raising the awareness of pediatricians and dermatologists regarding the most common dermatological diagnosis in those patient populations.

Although Klippel-Trenaunay syndrome (KTS) is an infrequently seen dermatological disorder with plethora of associations. It is largely a clinical diagnosis made by the presence of at least two of the three classic findings. We are reporting a 16-year-old male child who presented to us with the limb hypertrophy, portwine stains, congenital heart disease, and bony abnormality. Multiple associations of KTS make it an interesting case. [ABSTRACT FROM AUTHOR]

Ichthyosis and psoriasis both are inherently considered as disorders of abnormal keratinization. X-linked recessive ichthyosis (XLRI) is a genetic disorder, while psoriasis is sporadic in most cases. The underlying pathophysiology for their occurrence in the same patient is not well understood but may be attributed to genetic modifications or epigenetics. We hereby report a case of a 14-year-old male child with psoriasis vulgaris in the setting of XLRI. To our best knowledge, it has not been reported in the English literature to date.

Subcorneal pustular dermatosis (SPD), first described by Sneddon and Wilkinson, represents a rare chronic and relapsing sterile pustular eruptions generally involving the trunk and flexor aspect of limbs. Usually, it affects middle-aged or elderly women. Histologically, it is characterized by the accumulation of subcorneal neutrophils with an absence of spongiosis and acantholysis. Here, we are reporting a rare case of SPD in the pediatric age group, which was diagnosed based on clinical and histological findings. We gave dapsone in treatment with a positive outcome. To the best of our knowledge, there has not been any case report in the pediatric age group from India so far. [ABSTRACT FROM AUTHOR]

Anterior cervical hypertrichosis (ACH) is a very rare form of primary localized hypertrichosis. It is characterized by a tuft of terminal hairs on the anterior neck just above the laryngeal prominence. Although it frequently presents with an isolated defect, it can be associated with other abnormalities. Here, we report the case of a 12-year-old girl who presented to our outdoor with a complaint of localized excessive hairs over the anterior aspect of the neck. She also gave a history of the persistence of irregular hyperpigmented areas on the right cheek. The diagnosis of ACH with linear and whorled nevoid hypermelanosis was made. Their concurrence might be coincidental. So far, ACH associated with linear whorled nevoid hypermelanosis has not been reported in the literature. [ABSTRACT FROM AUTHOR]

Since the discovery of graphene in 2004, the unique properties of two-dimensional materials have sparked intense research interest regarding their use as alternative materials in various photonic applications. Transition metal dichalcogenide monolayers have been proposed as transport layers in photovoltaic cells, but the promising characteristics of group IV-VI dichalcogenides are yet to be thoroughly investigated. This manuscript reports on monolayer Ge 2 Se 2 (a group IV-VI dichalcogenide), its optoelectronic behavior, and its potential application in photovoltaics. When employed as a hole transport layer, the material fosters an astonishing device performance. We use ab initio modeling for the material prediction, while classical drift-diffusion drives the device simulations. Hybrid functionals calculate electronic and optical properties to maintain high accuracy. The structural stability has been verified using phonon spectra. The E - k dispersion reveals the investigated material's key electronic properties. The calculations reveal a direct bandgap of 1.12 eV for monolayer Ge 2 Se 2 . We further extract critical optical parameters using the Kubo-Greenwood formalism and Kramers-Kronig relations. A significantly large absorption coefficient and a high dielectric constant inspired the design of a monolayer Ge 2 Se 2 -based solar cell, exhibiting a high open circuit voltage of V oc = 1.11 V, a fill factor of 87.66%, and more than 28% power conversion efficiency at room temperature. Our findings advocate monolayer Ge 2 Se 2 for various optoelectronic devices, including next-generation solar cells. The hybrid quantum-to-macroscopic methodology presented here applies to broader classes of 2D and 3D materials and structures, showing a path to the computational design of future photovoltaic materials., (Copyright © 2024, Shrivastava et al.)
