ABSTRACT
Objective Multisystem infammatory syndrome (MIS-C) in children is a febrile illness that has overlapping presentation with other locally prevalent illnesses. Clinicolaboratory profle of children admitted with MIS-C and dengue were compared to understand their presentation at the outset. Methods This was a retrospective study of children?12 y admitted with MIS-C (WHO defnition) or laboratory-confrmed dengue between August 2020 and January 2021 at a tertiary center in North India. Results A total of 84 children (MIS-C - 40; dengue - 44) were included. The mean (SD) age [83.5 (39) vs. 91.6 (35) mo] was comparable. Rash (72.5% vs. 22.7%), conjunctival injection (60% vs. 2.3%), oral mucocutaneous changes (27.5% vs. 0) and gallop rhythm (15% vs. 0) were seen more frequently with MIS-C, while petechiae [29.5% vs. 7.5%], myalgia (38.6% vs. 10%), headache (22.7% vs. 2.5%), and hepatomegaly (68.2% vs. 27.5%) were more common with dengue. Children with MIS-C had signifcantly higher C-reactive protein (124 vs. 3.2 mg/L) and interleukin 6 (95.3 vs. 20.7 ng/mL), while those with dengue had higher hemoglobin (12 vs. 10.2 g/dL) lower mean platelet count (26 vs. 140× 109 /L), and greater elevation in aspartate (607 vs. 44 IU/L) and alanine (235.5 vs. 56 IU/L) aminotransferases. The hospital stay was longer with MIS-C; however, PICU stay and mortality were comparable. Conclusion In hospitalized children with acute febrile illness, the presence of mucocutaneous features and highly elevated CRP could distinguish MIS-C from dengue. The presence of petechiae, hepatomegaly, and hemoconcentration may favor a diagnosis of dengue.
ABSTRACT
Objectives: This prospective observational study aimed to identify the current trend of the circulating viral strains responsible for hand foot mouth disease (HFMD) outbreak in four tertiary care centers in Rajasthan, amidst the coronavirus disease (COVID-19) pandemic (April-October 2022). Methods: Cases with suspected HFMD, presenting to our skin outpatient department were assessed clinically and serologically (IgM antibodies against coxsackie virus (CV) A6, A16 and enterovirus 71) for evidence of the disease. Results: We identified 718 new HFMD patients (161 adults) with peaks in May and August, 2022. Male:female ratio decreased with increasing age. Most children were asymptomatic. A total of 385/409 patients assessed serologically, were found positive, most commonly against CV-A6. Conclusion: Though HFMD typically affects young children, an unusually higher proportion of adults were affected during the current pandemic. There were some differences between pediatric and adult presentation of HFMD.
ABSTRACT
Objective To describe the clinical and laboratory profle, management, intensive care needs, and outcome of children with toxic shock syndrome (TSS) admitted to the pediatric intensive care unit (PICU) of a tertiary care center in North India. Methods This retrospective study was conducted in the PICU of a tertiary care hospital in North India over a period of 10 y (January 2011–December 2020) including children<12 y with TSS (n=63). Results The median (interquartile range, IQR) age was 5 (2–9) y, 58.7% were boys, and Pediatric Risk of Mortality III (PRISM-III) score was 15 (12–17). The primary focus of infection was identifed in 60.3% children, 44.5% had skin and soft tissue infections, and 17.5% (n=11) had growth of Staphylococcus aureus. Common manifestations were shock (100%), rash (95.2%), thrombocytopenia (79.4%), transaminitis (66.7%), coagulopathy (58.7%), and acute kidney injury (AKI) (52.4%); and involvement of gastrointestinal (61.9%), mucus membrane (55.5%), respiratory (47.6%), musculoskeletal (41.3%), and central nervous system (CNS) (31.7%). The treatment included fuid resuscitation (100%), vasoactive drugs (92.1%), clindamycin (96.8%), intravenous immunoglobulin (IVIG) (92.1%), blood products (74.6%), mechanical ventilation (58.7%), and renal replacement therapy (31.7%). The mortality was 27% (n=17). The duration of PICU and hopsital stay was 5 (4–10) and 7 (4–11) d, respectively. Higher proportion of nonsurvivors had CNS involvement, transaminitis, thrombocytopenia, coagulopathy, and AKI; required mechanical ventilation and blood products; and had higher vasoactive–inotropic score. Conclusion TSS is not uncommon in children in Indian setup. The management includes early recognition, intensive care, antibiotics, source control, and adjunctive therapy (IVIG and clindamycin). Multiorgan dysfunction and need for organ supportive therapies predicted mortality.
ABSTRACT
Objectives To compare the epidemiological, clinical profle, intensive care needs and outcome of children hospitalized with SARS-CoV-2 infection during the frst and second waves of the pandemic. Methods This was a retrospective study of all children between 1 mo and 14 y, admitted to a dedicated COVID-19 hospital (DCH) during the frst (1st June to 31st December 2020) and second waves (1st March to 30th June 2021). Results Of 217 children, 104 (48%) and 113 (52%) were admitted during the frst and second waves respectively. One hundred ffty-two (70%) had incidentally detected SARS-CoV-2 infection, while 65 (30%) had symptomatic COVID-19. Comorbidities were noted in 137 (63%) children. Fifty-nine (27%) and 66 (30%) children required high-dependency unit (HDU) and ICU care respectively. Severity of infection and ICU needs were similar during both waves. High-fow oxygen (n=5, 2%), noninvasive ventilation [CPAP (n=34, 16%) and BiPAP (n=8, 5%)] and invasive ventilation (n=45, 21%) were respiratory support therapies needed. NIV use was more during the second wave (26% vs. 13%; p=0.02). The median (IQR) length (days) of DCH stay among survivors was longer during the frst wave [8 (6–10) vs. 5.5 (3–8); p=0.0001]. Conclusions Disease severity, associated comorbidities, PICU and organ support need and mortality were similar in the frst and second waves of the pandemic. Children admitted during the second wave were younger, had higher proportion of NIV use and shorter length of COVID-19 hospital stay.
ABSTRACT
Neisseria gonorrhoeae is a Gram-negative aerobic diplococcus bacterium that primarily causes sexually transmitted infections through direct human sexual contact. It is a major public health threat due to its impact on reproductive health, the widespread presence of antimicrobial resistance, and the lack of a vaccine. In this study, we used a bioinformatics approach and performed subtractive genomic methods to identify potential drug targets against the core proteome of N. gonorrhoeae (12 strains). In total, 12,300 protein sequences were retrieved, and paralogous proteins were removed using CD-HIT. The remaining sequences were analyzed for non-homology against the human proteome and gut microbiota, and screened for broad-spectrum analysis, druggability, and anti-target analysis. The proteins were also characterized for unique interactions between the host and pathogen through metabolic pathway analysis. Based on the subtractive genomic approach and subcellular localization, we identified one cytoplasmic protein, 2Fe-2S iron-sulfur cluster binding domain-containing protein (NGFG RS03485), as a potential drug target. This protein could be further exploited for drug development to create new medications and therapeutic agents for the treatment of N. gonorrhoeae infections.
ABSTRACT
Oral cancer is usually preceded by oral potentially malignant disorders (OPMDs) and early detection can downstage the disease. The majority of OPMDs are asymptomatic in early stages and can be detected on routine oral examination. Though only a proportion of OPMDs may transform to oral squamous cell carcinoma (OSCC), they may serve as a surrogate clinical lesion to identify individuals at risk of developing OSCC. Currently, there is a scarcity of scientific evidence on specific interventions and management of OPMDs and there is no consensus regarding their management. A consensus meeting with a panel of experts was convened to frame guidelines for clinical practices and recommendations for management strategies for OPMDs. A review of literature from medical databases was conducted to provide the best possible evidence and provide recommendations in management of OPMDs
ABSTRACT
Present study has been undertaken in order to assemble knowledge regarding physicochemical parameters analysis from June 2021 – May 2022 in relation to the abundance, composition and seasonal variation in the phytoplankton of Johila reservoir Lalpur Podki, Amarkantak (M.P.). It is interiorly located at Latitude 22046'20, Longitude, 81044'39'' in Lalpur and no study regarding hydrobiology in general and phytoplankton abundance in particular has yet not been conducted. Johila reservoir has its origin from Jwaleshwar temple kund of Amarkantak, hill located in Makel velly. It starts flowing opposite site to the Narmada River after 15 Kilometre and finally joins the river Sone at Dasrathghat of Umaria District of Madhya Pradesh. Total area of Johila reservoir is 86 hectare (216 acers). Since no study yet has been done on phytoplankton production in relation to its physico-chemical characteristic hence present study has been undertaken. Phytoplankton population were dominated by Chlorophyceae, Myxophyceae and Bacillariophyceae in decreasing order. Chlorophyceae members revealed dominance over Myxophyceae and Bacillariophyceae.
ABSTRACT
Introduction: The skin acts as the first line of defense for the body against external injuries. With aging, the architecture of the skin undergoes intrinsic changes that impair its capacity for repair. In addition, the aging skin is more susceptible to injury by external stimuli, including ultraviolet rays and environmental pollutants. The combination of these factors predisposes the elderly to a variety of dermatological disorders, including xerosis, pruritus, photoaging, eczematous disorders, and tumors. The elderly (>60 years of age) population in India accounted for 8.6% (104 million) in 2011, and the figure has been projected to increase to 19% by the year 2050. It is imperative to identify the pattern of cutaneous disorders in this population as skin care regimens aimed to improve epidermal function have been shown to be effective inthe prevention and treatment of some of these aging-associated cutaneous disorders. Objectives: The objective of the study was to identify the pattern of dermatoses among the elderly population attending the dermatology clinic at a tertiary care hospital in South?east Rajasthan. Materials and Methods: We conducted a cross-sectional descriptive study of patients above the age of 60 years who attended the dermatology clinic at a tertiary care hospital in South?east Rajasthan from May 2018 to May 2020. A combination of history, physical examination, and clinical investigations (when appropriate) were used to establish the diagnosis. Results: A total of 210 patients were included in this study. Most patients were between the age group of 60–65 years (40.47%). One hundred and thirty?eight were male (65.71%) and 72 were female (34.28%), with a male to female ratio of 1.9:1. Our study demonstrated that xerosis was one of the most common diagnoses seen in 126 cases (60%), followed by eczematous skin conditions seen in 82 cases (39%). Conclusion: The elderly constitute an important part of the population. Cutaneous disorders in the elderly range from mild disorders such as cherry angiomas to dermatological malignancies. Therefore, it is important to recognize the pattern of dermatosis in this population so that appropriate therapeutic and preventive strategies could be implemented.
ABSTRACT
Purpose: To develop a new age?appropriate visual function questionnaire for visually impaired children. Methods: The study was conducted in north India in 20,955 (97.3%) children ?15 years who underwent visual acuity examination. Of these 20,955 children, a total of 722 children were referred with unaided visual acuity less than 6/12 in any eye. Among these referred children, parents in the age group of 5–9 years and children between 10 and 15 years underwent interviews using LV Prasad Functional Visual Questionnaire?20 (LVP FVQ 20) and Indian Visual Functioning Questionnaire?33 (IND VFQ?33). Following this, multiple steps were undertaken that involved expert opinion for the removal of items on basis of zero variance and factor analysis along with calculation of Cronbach’s alpha. Results: A Cronbach’ alpha of 0.834 was calculated for the younger age group and 0.931 for the higher age group of children. Conclusion: A new robust age?appropriate questionnaire was developed and it was observed that there was a significant change in median score (that was derived for various domains after calculating the median for the items in various domains asked pre? and post?intervention in the form of glasses or surgery) for quality of visual function in the visually impaired children. A significant change in functional vision of visually impaired children (P < 0.005) was observed in both age groups
ABSTRACT
Objective: To study the outcomes of neonates back-referred from a tertiary care centre to special newborn care units (SNCUs) for step-down care. Methods: This prospective cohort study was conducted at a tertiary care neonatal unit and SNCUs in neighbouring states. We studied preterm and term neonates back-referred to district SNCUs from September, 2018 to April, 2019. The infants were followed up till 3 months corrected age, for mortality, re-hospitalization, emergency visits and unscheduled outpatient visits. Preterm inborn neonates <32 weeks gestation discharged directly to home formed the controls. Results: 201 back-referred neonates (study cohort) and 55 preterm neonates discharged to home (controls) were followed up till 3 months corrected age. Amongst the back-referred neonates, 5% died, 7% required re-hospitalization, 11% made emergency visits, and 24% made unscheduled outpatient visits. These outcomes were similar to the controls. Conclusion: Back-referral of convalescing neonates is a safe method of utilizing the limited healthcare resources in tertiary care centers in developing country settings.
ABSTRACT
Klebsiella pneumoniae is a gram-negative bacterium that is known for causing infection innosocomial settings. As reported by the World Health Organization, carbapenem-resistantEnterobacteriaceae, a category that includes K. pneumoniae, are classified as an urgentthreat, and the greatest concern is that these bacterial pathogens may acquire genetictraits that make them resistant towards antibiotics. The last class of antibiotics, carbapenems, are not able to combat these bacterial pathogens, allowing them to clonally expandantibiotic-resistant strains. Most antibiotics target essential pathways of bacterial cells;however, these targets are no longer susceptible to antibiotics. Hence, in our study, we focused on a hypothetical protein in K. pneumoniae that contains a DNA methylation proteindomain, suggesting a new potential site as a drug target. DNA methylation regulates theattenuation of bacterial virulence. We integrated computational-aided drug design by using a bioinformatics approach to perform subtractive genomics, virtual screening, and fingerprint similarity search. We identified a new potential drug, koenimbine, which could bea novel antibiotic.
ABSTRACT
Yersinia pestis, the cause of plague and a potential biological weapon, has always been a threatening pathogen. Some strains of Y. pestis have varying degrees of antibiotic resistance. Thus, this systematic review was conducted to alert clinicians to this pathogen’s potential antimicrobial resistance. A review of the literature was conducted for experimental reports and systematic reviews on the topics of plague, Y. pestis, and antibiotic resistance. From 1995 to 2021, 7 Y. pestis isolates with 4 antibiotic resistance mechanisms were reported. In Y. pestis 17/95, 16/95, and 2180H, resistance was mediated by transferable plasmids. Each plasmid contained resistance genes encoded within specific transposons. Strain 17/95 presented multiple drug resistance, since plasmid 1202 contained 10 resistance determinants. Strains 16/95 and 2180H showed single antibiotic resistance because both additional plasmids in these strains carried only 1 antimicrobial determinant. Strains 12/87, S19960127, 56/13, and 59/13 exhibited streptomycin resistance due to an rpsl gene mutation, a novel mechanism that was discovered recently. Y. pestis can acquire antibiotic resistance in nature not only via conjugative transfer of antimicrobial-resistant plasmids from other bacteria, but also by gene point mutations. Global surveillance should be strengthened to identify antibiotic-resistant Y. pestis strains by whole-genome sequencing and drug susceptibility testing.
ABSTRACT
@#Knee osteoarthritis is the commonest cause of knee pain in the elderly. It is characterized by unresolved pain, limitation of motion and reduced quality of life. Total knee arthroplasty (TKA) is a safe and effective method in treating chronic knee osteoarthritis. We report a rare case of a seventy-seven-year-old Chinese female with multiple comorbidities and bilateral degenerative osteoarthritis who had sought services of traditional and complementary medicine (TCM) for pain relief. The patient experienced unresolved pain and superficial skin scars following the unregulated procedure. This paper aims to outline the importance of awareness among surgeons regarding the unregulated practice of TCM that may exacerbate chronic osteoarthritis, joint synovitis, influence the surgical approach for future procedures with the presence of scars and prosthetic joint infection risk.
ABSTRACT
BACKGROUND@#Different methods have been used to inject stem cells into the eye for research. We previously explored the intravitreal route. Here, we investigate the efficacy of intravenous and subretinal-transplanted human dental pulp stem cells (DPSCs) in rescuing the photoreceptors of a sodium iodate-induced retinal degeneration model. @*METHODS@#Three groups of Sprague Dawley rats were used: intervention, vehicle group and negative control groups (n = 6 in each). Intravenous injection of 60 mg/kg sodium iodate (day 0) induced retinal degeneration. On day 4 postinjection of sodium iodate, the rats in the intervention group received intravenous DPSC and subretinal DPSC in the right eye; rats in the vehicle group received subretinal Hank’s balance salt solution and intravenous normal saline; while negative control group received nothing. Electroretinogram (ERG) was performed to assess the retinal function at day 0 (baseline), day 4, day 11, day 18, day 26, and day 32. By the end of the study at day 32, the rats were euthanized, and both their enucleated eyes were sent for histology. @*RESULTS@#No significant difference in maximal ERG a-wave (p = 0.107) and b-wave, (p= 0.153) amplitude was seen amongst the experimental groups. However, photopic 30 Hz flicker amplitude of the study eye showed significant differences in the 3 groups (p = 0.032). Within the intervention group, there was an improvement in 30 Hz flicker ERG response of all 6 treated right eyes, which was injected with subretinal DPSC; while the 30 Hz flicker ERG of the nontreated left eyes remained flat. Histology showed improved outer nuclear layer thickness in intervention group; however, findings were not significant compared to the negative and vehicle groups. @*CONCLUSION@#Combination of subretinal and intravenous injection of DPSCs may have potential to rescue cone function from a NaIO3 -induced retinal injury model.
ABSTRACT
Lip and oral cavity cancer, which can occur in any part of the mouth, is the 11th most common type of cancer worldwide. The major obstacles to patients’ survival are the poor prognosis, lack of specific biomarkers, and expensive therapeutic alternatives. This study aimed to identify the main genes and pathways associated with lip and oral cavity carcinoma using network analysis and to analyze its molecular mechanism and prognostic significance further. In this study, 472 genes causing lip and oral cavity carcinoma were retrieved from the DisGeNET database. A protein-protein interaction network was developed for network analysis using the STRING database. VEGFA, IL6, MAPK3, INS, TNF, MAPK8, MMP9, CXCL8, EGF, and PTGS2 were recognized as network hub genes using the maximum clique centrality algorithm available in cytoHubba, and nine potential drug candidates (ranibizumab, siltuximab, sulindac, pomalidomide, dexrazoxane, endostatin, pamidronic acid, cetuximab, and apricoxib) for lip and oral cavity cancer were identified from the DGIdb database. Gene enrichment analysis was also performed to identify the gene ontology categorization of cellular components, biological processes, molecular functions, and biological pathways. The genes identified in this study could furnish a new understanding of the underlying molecular mechanisms of carcinogenesis and provide more reliable biomarkers for early diagnosis, prognostication, and treatment of lip and oral cavity cancer.
ABSTRACT
@#Introduction: Biofilm is one of the important virulence factors that is responsible for the severity and progression of the Streptococcus pyogenes diseases. M-protein is involved in the irreversible attachment of S. pyogenes to surfaces during biofilm development. This study aims to determine the propensity of S. pyogenes to form biofilms and the molecular epidemiology of S. pyogenes isolates by emm typing. Methods: We screened 45 S. pyogenes isolates for the biofilm formation by Congo red agar (CRA) and quantified the biofilms by crystal violet microtiter-plate methods (CVMtP). The emm typing of all isolates was performed by conventional PCR with established primers according to the CDC protocol. Results: Majorities of S. pyogenes were isolated from non-invasive, 27 (60.0%) than invasive sources, 18 (40.0%). Regardless of invasiveness, 40 (88.9%) S. pyogenes isolates formed black colonies on CRA, while 43 (95.6%) of the isolates demonstrated various degrees of biofilm formation by CVMtP method. A total of 30 different emm types and subtypes were identified. No new emm types/subtypes were detected. The predominant emm types/subtypes were emm1, emm63, emm18.21, emm91, and emm97.4 which each gene accounted for 7.0%. All emm types/subtypes of S. pyogenes produced biofilms by CVMtP method except emm17.2 and emm57 which were isolated from non-invasive sources. Conclusions: Biofilm-producing S. pyogenes strains of various sources are genetically diverse and biofilm phenotypes are inherent to individual characteristic rather than specific emm type. Nonetheless, higher propensity of GAS to form biofilms warrants better management strategies to avoid treatment failures in the future.
ABSTRACT
@#Introduction: The internalization process of group A streptococci (GAS) into human cells is one of the crucial steps in the pathogenesis of GAS infections, which could also affect their susceptibility responses toward several antibiotics. Currently, data on the distribution of internalization-associated genes and susceptibility patterns are still lacking in Malaysia. This study investigated the distribution of fibronectin-binding protein F1 (prtF1) and streptococcal pyrogenic exotoxin B (speB) genes in GAS isolates with their susceptibility profiles and source of samples. Methods: We used 43 GAS isolates from our previous stock culture and performed antibiotic susceptibility testing by Kirby-Bauer disk diffusion method and interpreted the results according to the established guidelines. We detected virulence (prtF1 and speB) and resistance (ermA, ermB, mefA, tetM and lnuA) genes by PCR method using established primers and protocols. Results: High resistance rates were observed against doxycycline (58.1%) and clindamycin (16.3%). In comparison, 100.0% and 46.5% of GAS isolates carried speB and prtF1 genes, respectively. tetM and lnuA genes were detected in all respective resistant isolates (100% for each). No macrolide resistance genes were detected. Interestingly, prtF1 gene was highly distributed in doxycycline-resistant than doxycycline-sensitive isolates (60.0% versus 27.8%). Conclusions: High resistance rate of GAS toward doxycycline in our study may potentially reflect the uncontrol dissemination of tetM gene among our isolates. The presence of prtF1 gene among this strain would enhance its ability to evade the intracellular action of antibiotics, which may affect the management of GAS diseases. Thus, close monitoring of GAS by molecular methods is required in the future.

ABSTRACT
@#This work investigates the Musa Paradisiaca plant and its tepal extracts. The research findings show that the tepal extracts of M. Paradisiaca contain high phytochemical activity. Hence we can conclude that these plants have a number of beneficial properties. Phytochemical analysis concludes that the plant is rich in flavonoids, phenolic compounds, tannins, terpenoids, and phytosterol. In the current work, silver nanoparticles (AgNPs) have revealed the antioxidant properties of M. Paradisiaca. The results show that the methanolic extracts of these tepals exhibit antioxidant potential and are also sources of natural antioxidant compounds, though comparatively, AgNPs have shown the best antioxidant activity. This work investigates the link between the ethnopharmacological statements and the bioactive constituents found in M. Paradisiaca toward all probable markers for cervical cancer via in vivo studies and molecular docking, to form a pharmacophore setting for the active target. However, most of the mechanisms of action of herbal medicines are not in total agreement, and the information collected from their traditional remedies over the years must not be neglected. Hence, it is sensible to investigate the options available in herbal medicine for cancer progression. Biosynthesised AgNPs are principally spherical and nanosized. It was also found that tepalmediated AgNPs exhibit excellent antimicrobial efficacy against tested human pathogens. This green method can be used as a better alternative source than the chemical fabrication of nanomaterials and the biosynthesised nanoparticles can be used in antibacterial medicines. The methanolictepal extract of M. Paradisiaca with AgNPs displayed proficient antidiabetic properties in the diabetes rat model and so could have a possible development for medical use in the future
