Abstract
The Zika virus (ZKV) is a single-stranded positive-sense, enveloped RNA virus. Zika infection during pregnancy can cause congenital microcephaly, Guillain-Barré syndrome, miscarriage, and other CNS abnormalities. The world needs safe and effective vaccinations to fight against ZIKV infection since vaccination is generally regarded as one of the most effective ways to prevent infectious diseases. In the present work, we used immunoinformatics and docking studies to construct a vaccine containing multi-epitopes using the structural and non-structural proteins of ZKV. The structural models of ZKV proteins (PrE, PrM, NS1, and NS2A) were constructed using Pyre2 and RaptorX servers. The epitopes of B-cell, T-cell (HTL and CTL), and IFN-γ were predicted, and each epitope's immunogenic nature and physiochemical properties were confirmed. As an adjuvant, the CPG-Oligodeoxynucleotide, an agonist of Toll-like receptor 9 (TLR9), is associated to cytotoxic T-lymphocytes (CTL) epitopes via PAPAP linker. To assess the binding affinity and the tendency of the designed vaccine to induce an immune response through TLR9, molecular docking was done. In the next step, molecular dynamics (MD) simulation to 100 nanoseconds (ns) was used to evaluate the stability of the interaction of the designed vaccine with TLR9. The designed vaccine is predicted to be highly antigenic, non-toxic, soluble, and stable with low flexibility in MD simulation. MD studies indicated that the finalized vaccine-TLR9 docked complex was stable during simulation time. The vaccine construct is able to stimulate both humoral and cellular immune responses. We suppose that our constructed model of the vaccine may have the ability to induce the host immune response against ZKV. Further studies, including in vitro and in vivo experimental analyses, are needed to prove the constructed vaccine's efficacy with multi-epitopes.Communicated by Ramaswamy H. Sarma.

Discovery of potential FGFR3 inhibitors via QSAR, pharmacophore modeling, virtual screening and molecular docking studies against bladder cancer. J Transl Med 2023; 21:111. [PMID: 36765337 PMCID: PMC9913026 DOI: 10.1186/s12967-023-03955-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 02/01/2023] [Indexed: 02/12/2023] Open
Abstract
BACKGROUND Fibroblast growth factor receptor 3 is known as a favorable aim in vast range of cancers, particularly in bladder cancer treatment. Pharmacophore and QSAR modeling approaches are broadly utilized for developing novel compounds for the determination of inhibitory activity versus the biological target. In this study, these methods employed to identify FGFR3 potential inhibitors. METHODS To find the potential compounds for bladder cancer targeting, ZINC and NCI databases were screened. Pharmacophore and QSAR modeling of FGFR3 inhibitors were utilized for dataset screening. Then, with regard to several factors such as Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) properties and Lipinski's Rule of Five, the recognized compounds were filtered. In further step, utilizing the flexible docking technique, the obtained compounds interactions with FGFR3 were analyzed. RESULTS The best five compounds, namely ZINC09045651, ZINC08433190, ZINC00702764, ZINC00710252 and ZINC00668789 were selected for Molecular Dynamics (MD) studies. Off-targeting of screened compounds was also investigated through CDD search and molecular docking. MD outcomes confirmed docking investigations and revealed that five selected compounds could make steady interactions with the FGFR3 and might have effective inhibitory potencies on FGFR3. CONCLUSION These compounds can be considered as candidates for bladder cancer therapy with improved therapeutic properties and less adverse effects.

Abstract
PURPOSE Molecular mechanisms of uveal melanoma development in association with high pigmentation are unclear. Tyrosinase Related Protein (TYRP1) is not only one of the important melanogenesis marker that contributes to melanin synthesis, but can also prevents the melanocyte death. The induction of melanogenesis leads to induction of HIF-1α which can affect the behavior of melanoma cells and its surrounding environment. The aim of our study was to determine the expression of TYRP1 and HIF-1α at the protein and RNA level and determine its prognostic significance. METHODS In the present study, the expression of TYRP1 and HIF-1α was investigated on 61 formalin-fixed paraffin-embedded choroidal melanoma samples by immunohistochemistry. Fresh 50 samples were validated by real-time PCR. Results were correlated with clinicopathological parameters and Kaplan-Meier was performed to determine the prognostic significance. RESULTS High immunoexpression of TYRP1 and HIF-1α was present in 61 and 54% of patients, respectively. Both TYRP1 and HIF-1α correlated well with high pigmentation and BAP1 (BRCA1 Associated Protein-1) loss (p < 0.05) at IHC level as well as transcriptional level. There was reduced metastatic free survival in patients with necrosis and this was statistically significant (p = 0.010). CONCLUSION Our findings indicate that TYRP1 can be used as a potential biomarker in the development of targeted therapy in UM. Further studies on melanogenesis markers associated with TYRP1 could provide us a better understanding in this field.

Patient tracking during treatment of children with cancer in India - An exploratory study. Cancer Rep (Hoboken) 2021; 5:e1359. [PMID: 33624448 PMCID: PMC9199505 DOI: 10.1002/cnr2.1359] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 01/18/2021] [Accepted: 02/03/2021] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Abandonment of treatment, a major cause of treatment failure in low- and middle-income countries like India, is particularly high during the diagnostic and initial phase of treatment. Tracking of patients during this risk period may reduce treatment abandonment rates and increase quality of care. AIM The primary aim was to pilot the use and check the acceptability of a tool for tracking children with cancer in New Delhi during the initial part of their treatment. Secondary aim was to estimate abandonment rates among these patients. METHODS This prospective study was carried out in two centers of North India in New Delhi and enrolled children less than 18 years diagnosed with cancer at these centers and who had registered with Cankids for social support. Parent support group (PSG) workers maintained contact with the child's family at least once a week for the first 12 weeks. Details of each contact and subsequent action were recorded in a customized book (called "You are not alone" or YANA Book). Descriptive analysis of these contacts was done in Microsoft Excel and presented in frequencies and percentages. The five-point Likert scale was used to check the acceptability of the tool among the PSG workers. RESULTS Seven PSG workers enrolled and tracked 81 patients (73% male with a median age of 6 years). During the 12-week study period, 986 contacts were attempted and three (3.7%) patients had abandoned their treatment. All PSG workers strongly agreed that the YANA book was simple to understand and use, decreased their workload, and helped provide better assistance to patients. CONCLUSION The tool for patient tracking was well accepted by the PSG workers and considered easy to use. We now plan to implement our model as a routine service at all the partnering hospitals in India.

Abstract
PURPOSE Uveal melanoma (UM) is the most common intraocular cancer with a high mortality rate that requires new research in the field of prevention and treatment. c-REL is a member of the nuclear factor κB (NF-κB) transcription factor family and an emerging regulator of tumorigenesis. Therefore, the objective of the study is to evaluate the constitutive expression of c-REL in uveal melanoma patients and its prognostic significance. METHODS Detection of c-REL expression was carried out by immunohistochemistry in all 75 patients, and qRT-PCR performed on 58 fresh cases of uveal melanoma along with IL-6 status. Immunoblot was performed to validate immunohistochemistry results. Expression of c-REL protein correlated with clinicopathological parameters and overall survival of patients. RESULTS Immunohistochemistry results revealed nuclear expression of the c-REL protein (56%) in our cases. Out of 75 cases, 31 cases showed nuclear expression, and 11 cases had cytoplasmic expression. qRT-PCR showed upregulation of the REL gene in 56.89% cases at the transcriptional level. There was a statistically significant difference in the overall survival of patients with c-REL nuclear immunopositivity (p = 0.0048). On multivariate analysis, scleral invasion and c-REL nuclear expression found to be an independent prognostic factor (p < 0.05) CONCLUSIONS: To the best of our knowledge, this was the first study reporting the expression of the c-REL protein in uveal melanoma. Strong nuclear immunoexpression of c-Rel suggests NFκB pathway activation which might be involved in the progression of the disease. Differential expression of c-REL protein may be used as an attractive target for the development of anticancer strategies.

Abstract
Background: Diagnosis of cancer in a child places considerable economic burden on families. The health expenditures are more catastrophic in resource limited countries like India where GDP spend on health is just over 1% and financing of treatment is usually out-of-pocket (OOP). Consequently parents may abandon their child's cancer treatment to ensure financial sustainability of the family. Research in this area is mostly from resource rich countries and OOP expenditure burden remains unknown in India. Aim: The objective of this study is to describe the OOP expenditure incurred by families of children (< 18 years age) with cancer being treated in India prior to and during cancer directed treatment. Methods: A prospective cost of illness study from a family household perspective was conducted in 14 centers (5 public, 5 private and 4 charitable trust sector) in 4 cities in India from 2016-2018. Baseline family demographic and socioeconomic data were collected followed by OOP expenditure incurred prior to start of treatment. For the duration of the child's treatment, a social worker contacted parents at regular intervals to record their expenditure on cancer directed treatment. Data collection was stopped when one of these happened - completion of treatment or death or progression/relapse or abandonment or transfer. Data were described descriptively and a univariate/multivariate analysis using logistic regression was done to detect factors associated with OOP expenditure. Results: 394 children (63% male, median age 5 years) with cancer (64% leukemia/lymphoma, 33% solid tumors, 3% CNS tumors) were enrolled from public (45%), charitable trust (28%) and private (27%) sector hospitals. They were symptomatic for a median duration of 6 weeks (range 0 to 104 weeks). 88% had no insurance and 73% were from families with monthly income of ≤ 10,000 rupees (≤ 159 US$). Mean OOP expenditure was Rs 209,500 (3325 US$) which is 195% of per capita income (1706 US$) of India. OOP expenditure from onset of symptoms to start of treatment was Rs 53,104 (843 US$) of which 77% was medical (15% laboratory tests, 11% medicines, 9% hospital bed costs) and 23% nonmedical (12% travel, 6% food, 3% lodging). OOP expenditure on cancer directed treatment was Rs 156,396 (2482 US$) of which 64% was medical (9% hospital bed costs, 9% supportive care drugs, 8% laboratory tests) and 36% nonmedical (19% food, 9% travel, 6% lodging). On univariate analysis age, gender, city, type of treatment facility, insurance, type of cancer, driving time and distance were significantly associated with OOP expenditure but only insurance and type of treatment facility were found significant on multivariate analysis. Conclusion: Families of children with cancer incur significant OOP expenditure prior to and during cancer directed treatment, which includes a significant portion on nonmedical expenses. Expenditure varied significantly by insurance and type of treatment facility.

Abstract
BACKGROUND Febrile neutropenia is a life-threatening emergency in pediatric cancer patients. Its management is based on established guidelines that emphasize on prompt action. Consideration of local microbiologic spectrum and its susceptibility is pivotal in devising a rational protocol. AIMS To study the spectrum of bacterial isolates and its antibiotic sensitivity profile in bloodstream infections (BSIs) of pediatric cancer patients. SETTINGS AND DESIGN Retrospective study. MATERIALS AND METHODS This study was conducted at a tertiary cancer center for pediatric cancer patients. Blood culture samples sent during the evaluation of patients with clinical diagnosis of febrile neutropenia during the year of 2013 were analyzed. The microbiological and antibiotic sensitivity patterns were studied. RESULTS A total of 27 isolates represented BSIs out of 412 blood cultures sent (6.5%). These were predominantly Gram-negative (92%) with Klebsiella contributing to the majority of them. Extended spectrum beta-lactamase production was seen in 59% of all isolates. Multidrug resistance phenotype was seen in 48%, extreme drug resistance in 32% and pan drug resistance in 16% of Gram-negative isolates. Klebsiella predominated in all of these isolates. Mortality resulted in 15% isolates, majorly contributed by Klebsiella. Colistin was the most sensitive antibiotic (75% sensitivity) and in significant number of cases the only salvage option. CONCLUSION Gram-negative bacteria are the most common etiologic agents. The emergence of drug resistant strains of Klebsiella and the poor sensitivity of most of these strains to common first choice empiric agents is alarming. Low prevalence of Gram-positive organisms questions the routine use of empiric vancomycin.

Abstract
Annual influenza immunisation is the recommended practice for people such as the elderly, for whom influenza poses a substantial risk of serious illness and death. Influenza vaccines are effective in preventing, or ameliorating influenza, reducing complications and mortality (Department of Health, 2001, 2002). In long-stay residential accommodation, influenza immunisation should prevent rapid spread of infection causing outbreaks (Communicable Disease Centre, 2003). This paper reports on two outbreaks of influenza that occurred in vaccinated elderly in residential institutions. In both outbreaks the isolated virus strain was included in the composition of the influenza vaccine for that winter season. Suboptimal protection against influenza may be provided in the vaccinated elderly, due to declining competency of the ageing immune system. Furthermore, the occurrence in the late winter of these outbreaks may demonstrate waning immunity following immunisation early in the season.

Abstract
BACKGROUND Acute lymphoblastic leukemia survivors are predisposed to obesity. However, the exact underlying mechanisms are not known. AIMS The study was done to assess the role of biomarkers of obesity in acute leukemia survivors. SETTINGS AND DESIGNS This is a cross-sectional study conducted at All India Institute of Medical Sciences in survivors of acute leukemia who had completed treatment at least 1 year before enrollment in this study. MATERIALS AND METHODS Obesity was studied by determining the body mass index. Potential biomarkers were studied by assessing serum leptin, resistin, and adiponectin by enzyme-linked immunosorbant assay, and the results were compared in obese versus nonobese survivors. STATISTICAL ANALYSIS Descriptive analysis for baseline demographic factors and Student's t-test for comparing the mean levels of biomarkers among the obese and nonobese survivors. RESULTS One hundred and fifty-nine acute leukemia patients were enrolled in this study with a median follow-up of 36.8 months. The median age was 10 (range: 3-18) years, and 123 (77.3%) patients were males. The overall prevalence of overweight/obesity was 26.4%, and this was similar in acute myeloid leukemia and acute lymphoblastic leukemia sub-groups (26.2% vs. 27.3%, P = 0.9). Mean serum leptin and resistin were similar in obese and nonobese leukemia survivors (3.7 vs. 2.85 pg/mL, P = 0.064; 8.01 vs. 9.33 ng/mL, P = 0.36). However, mean serum adiponectin was significantly lower in obese leukemia survivors (7.97 vs. 11.5 μg/mL, P = 0.023). CONCLUSIONS Obese leukemic survivors had lower serum adiponectin levels than nonobese survivors. However, serum resistin and leptin levels were similar in the two groups.

Abstract
PURPOSE Short stature has been reported in pediatric cancer survivors. Data on retinoblastoma survivors are limited. We conducted a cross-sectional study to assess the height in retinoblastoma survivors. METHOD The recorded height was compared with median height for age and sex as per the Indian Academy of Pediatrics. Z-score less than -2 was considered short statured. RESULT Thirty percent of the survivors were short statured. The mean height was shorter than the mean 50th percentile height (119.7 ± 14.8 vs 128.7 ± 15 cm, p < 0.001). Previous chemotherapy showed a trend toward association (p = 0.09). CONCLUSION Short stature affects a significant number of retinoblastoma survivors.

Abstract
BACKGROUND Data on patients with localized Ewing sarcoma family of tumors (ESFT) who have received a uniform chemotherapy protocol are minimal. METHODS This is a single institutional review of patients with ESFT treated between June 2003 and November 2011. RESULTS 224/374 (60%) patients with ESFT presented with localized disease; median age was 15 years (range: 0.1-55). Ninety-nine patients underwent surgery of which 50 received adjuvant radiotherapy; 80 patients received radical radiotherapy following neoadjuvant chemotherapy. At median follow-up of 40.2 months (range: 1.3-129), 5-year EFS, OS, and local-control-rate, were 36.8 ± 3.6%, 52.4 ± 4.3%, and 63 ± 4.3%, respectively. In multivariate analysis, tumor diameter > 8 cm (P = 0.03), symptom duration > 4 months (P = 0.04), and WBC > 11 × 10(9) /L (P = 0.003) predicted inferior EFS; spine/abdomino-pelvic primary (P = 0.009) and WBC > 11 × 10(9) /L (P = 0.003) predicted inferior OS. Tumor size > 8 cm (P = 0.03) and radical radiotherapy as local treatment (P = 0.01) predicted inferior local-control-rate. CONCLUSION Prognostic hazard models for EFS and OS based on significant prognostic factors suggested that patients with combination of ESFT of spine/abdomino-pelvic region and baseline WBC > 11 × 10(9) /L had inferior OS (hazard ratio 4.44, P < 0.001) while patients with combination of ESFT with symptom duration > 4 months, tumor diameter > 8 m and baseline WBC > 11 × 10(9) /L had inferior EFS (hazard ratio 3.89, P = 0.002).
