RESUMEN

Introduction A wound that has not healed in a timely and organized manner to maintain its anatomical and functional integrity is considered chronic. It can last anywhere from four weeks to over three months and could be caused by trauma, diabetes, vascular disease, infection, or pressure. The primary objective of the study was to determine the prevalence of wounds in a rural and urban community in India, and the secondary objective was to evaluate the effect of various chronic wounds on quality of life (QoL) as assessed by the Short-Form Health Survey-36 (SF-36) questionnaire. Materials and methods The present study is a cross-sectional analytical study done between June 2022 and December 2023, and a total of 10,003 sample population was screened in Varanasi district, Uttar Pradesh, India. The study involved conducting a door-to-door survey of the population sample under interest based on a stratified sampling technique. During the survey, the epidemiological profile of the sample population, a detailed history, and clinical examination findings were recorded in a proforma. The reports of relevant diagnostic investigations were also recorded.  Results The overall prevalence of chronic wounds was 1.89 per 1000 (19/10003) population. The prevalence of wounds in urban areas was 1.57 per 1000 (11/6984) population, while that in rural communities was 2.64 per 1000 (8/3019) population. Of the total 19 patients with chronic wounds, the majority of the patients, i.e., seven each (36.8%), had diabetic foot ulcers (DFUs) and neglected/uncared trauma as the etiology for chronic wounds. The remaining five (5.3%) patients were equally divided between cellulitis, venous ulcers, trophic ulcers, tubercular ulcers, and malignancy as the etiology for chronic wounds. The QoL data suggested that 11 (57.9%) patients reported their general health status as fair with wounds, followed by five (26.3%) reporting their general health status as poor. Only three (15.8%) of the patients with wounds reported their general health condition as good. There was no significant difference between the QoL of rural and urban patients with chronic wounds. The overall prevalence of wounds has decreased from 15.03 to 1.89 per 1000 people in the survey locality. The switch from opting for home-based remedies to supervised care under the clinician (be it in a private or public setting) clearly indicates raised awareness regarding the management of wounds, and with time, people have shown an increased interest in healthcare facility treatment under supervision over adopting home remedies for wound treatment. The same domain may be attributed to the prompt management and efficacy of the management protocols by the treating physicians in India. Conclusion  The findings of the present study regarding the incidence and prevalence of chronic wounds in connection to demographic factors are important when allocating resources and making healthcare plans. The present study conveys a clear message to healthcare practitioners about the necessity of carrying out large-scale epidemiological research on this topic and offers a solid foundation for future studies.

RESUMEN

OBJECTIVES: Breast cancer is among the most heterogeneous and aggressive diseases and a foremost cause of death in women globally. Hypoxic activation of HIF-1α in breast cancers triggers the transcription of a battery of genes encoding proteins that facilitate tumor growth and metastasis and is correlated with a poor prognosis. Based on the reported cytotoxic and anti-cancer properties of Moringa oleifera (Mo), this study explores the inhibitory effect of bioactive compounds from M. oleifera and breast cancer target proteins HIF-1α, VEGF, and GLUT-1 in silico. METHODS: The X-ray crystallographic structures of HIF-1α, VEGF, and GLUT1 were sourced from the Protein Data Bank (PDB) and docked with 70 3D PubChem structures of bioactive compounds of M. oleifera using AutoDock Vina, and binding modes were analyzed using Discovery Studio. Five compounds with the highest binding energies were selected and further drug-likeness, oral bioavailability, ADME, and toxicity profiles were analyzed using SwissADME, ADMETSaR, and ADMETlab 3.0 web server. RESULTS: Out of the screened 70 bioactive compounds, the top five compounds with the best binding energies were identified namely Apigenin, Ellagic Acid, Isorhamnetin, Luteolin, and Myricetin with each receptor. Molecular docking results indicated that the ligands interact strongly with the target HIF-1α, VEGF, and GLUT-1 receptors through hydrogen bonds and hydrophobic interactions. These compounds showed favorable drug-like and pharmacokinetic properties, possessed no substantial toxicity, and were fairly bioavailable. CONCLUSIONS: Results suggested that the compounds possess strong potential in developing putative lead compounds targeting HIF-1α that are safe natural plant-based drugs against breast cancer.

RESUMEN

Photodynamic therapy (PDT) has evolved as a new therapeutic modality for cancer treatment with fewer side effects and drug resistance. Curcumin exhibits PDT activity, but its low bioavailability restricts its clinical application. Here, the bioavailability of curcumin was increased by its complex formation with the Zn(II) center. For a structure-activity relationship study, Zn(II)-based complexes (1-3) comprising N^N-based ligands (2,2'-bipyridine in 1 and 2 or 1,10-phenanthroline in 3) and O^O-based ligands (acetylacetone in 1, monoanionic curcumin in 2 and 3) were synthesized and thoroughly characterized. The X-ray structure of the control complex, 1, indicated a square pyramidal shape of the molecules. Photophysical and TD-DFT studies indicated the potential of 2 and 3 as good visible light type-II photosensitizers for PDT. Guided by the TD-DFT studies, the low-energy visible light-triggered singlet oxygen (1O2) generation efficacy of 2 and 3 was explored in solution and in cancer cells. As predicted by the TD-DFT calculations, these complexes produced 1O2 efficiently in the cytosol of MCF-7 cancer cells and ultimately displayed excellent apoptotic anticancer activity in the presence of light. Moreover, the molecular docking investigation showed that complexes 2 and 3 have very good binding affinities with caspase-9 and p-53 proteins and could activate them for cellular apoptosis. Further molecular dynamics simulations confirmed the stability of 3 in the caspase-9 protein binding site.

RESUMEN

ABSTRACT Introduction: Idiopathic steroid resistant nephrotic syndrome (SRNS) has variable outcomes in children. The primary objective of the present study was to assess the cumulative remission rate and the secondary objectives were to assess factors affecting the remission status, kidney function survival, and adverse effects of medications. Methods: One hundred fourteen patients with SRNS were included. Calcineurin inhibitor-based treatment protocol along with prednisolone and angiotensin-converting enzyme inhibitor were used, and patients were followed over 5 years. Results: Median age was 4.5 years; 53.5% of cases were between 1 to 5 years of age. Sixty-two patients (54.4%) were at initial stage and 52 (45.6%) were at a late SRNS stage. Median eGFRcr was 83.5 mL/min/1.73m2 at presentation. Of the 110 patients, 63 (57.3%) achieved remission [complete remission 30 (27.3%), partial remission 33 (30%)], and 47 (42.7%) had no remission. Kidney function survival was 87.3% and 14 cases (12.7%) had progression to CKD (G3-8, G4-3, G5-1, and G5D-2). Median duration of follow up was 36 months (IQR 24, 60). Age of onset, cyclosporine/tacrolimus, eGFRcr, and histopathology (MCD/FSGS) did not affect remission. Similarly, remission status in addition to age of onset, drug protocol, and histopathology did not significantly affect kidney function during a period of 5 years. Hypertension, cushingoid facies, short stature, cataract, and obesity were observed in 37.7, 29.8, 25.5, 17.5, and 0.7% of cases, respectively. Conclusion: About half of the cases achieved remission. Age of onset of disease, cyclosporine/tacrolimus use, and histopathological lesion neither affected remission status nor short-term kidney function survival in SRNS.


RESUMO Introdução: A síndrome nefrótica idiopática córtico-resistente (SNICR) apresenta desfechos variáveis em crianças. O objetivo principal deste estudo foi avaliar a taxa de remissão cumulativa. Os objetivos secundários foram avaliar fatores que afetam status de remissão, sobrevida da função renal e efeitos adversos de medicamentos. Métodos: Foram incluídos 114 pacientes com SNCR. Utilizou-se protocolo de tratamento baseado em inibidores de calcineurina juntamente com prednisolona e inibidor da enzima conversora de angiotensina. Os pacientes foram acompanhados durante 5 anos. Resultados: A idade mediana foi 4,5 anos; 53,5% dos casos tinham entre 1 e 5 anos. 62 pacientes (54,4%) estavam em estágio inicial; 52 (45,6%) em estágio tardio da SNCR. A TFGecr mediana foi 83,5 mL/min/1,73 m2 na apresentação. Dos 110 pacientes, 63 (57,3%) alcançaram remissão [remissão completa 30 (27,3%), remissão parcial 33 (30%)], e 47 (42,7%) não apresentaram remissão. A sobrevida da função renal foi 87,3%; 14 casos (12,7%) progrediram para DRC (G3-8, G4-3, G5-1, G5D-2). A duração mediana do acompanhamento foi 36 meses (IIQ 24, 60). Idade no início, ciclosporina/tacrolimus, TFGecr e histopatologia (DLM/GESF) não afetaram a remissão. Igualmente, status de remissão, além da idade no início, protocolo de medicamentos e histopatologia não afetaram significativamente a função renal por 5 anos. Observou-se hipertensão, fácies cushingoide, baixa estatura, catarata e obesidade em 37,7; 29,8; 25,5; 17,5; e 0,7% dos casos, respectivamente. Conclusão: Aproximadamente metade dos casos alcançou remissão. Idade no início, uso de ciclosporina/tacrolimus e lesão histopatológica não afetaram o status de remissão nem a sobrevida da função renal a curto prazo na SNICR.
