COMPARATIVE EVALUATION OF ORAL MICROBIOTA OF CHILDREN WITH AND WITHOUT EARLY CHILDHOOD CARIES BORN TO CARIES FREE MOTHERS

Objectives: To compare the level of mutans streptococci in children with and without Early childhood caries (ECC) born to caries free mothers.Methods: Twenty children aged between 3 and 6 years were selected depending on their caries experience, and the mother should be caries free inboth the groups. The children were divided into two groups. Group I had an active carious lesion and Group II were caries free. Saliva samples werecollected from the child and the mother in a sterile tube and bacterial culture was carried out to estimate the colony count.Results: There was a highly significant difference in the colony forming unit (CFU) between the 2 groups, indicating higher CFU in children with ECC.Conclusions: Even though there are higher chances of vertical transmission of MS from mother to their child, this study provides a new view thatmother alone is not a potential factor for mutans streptococci transmission to their child.Keywords: Mutans streptocci, Early childhood caries, Colony forming unit

Complete genome sequences of Rhizobium sp. strain SL42 and Hydrogenophaga sp. strain SL48, microsymbionts of Amphicarpaea bracteata

This study comprehensively analyzed two distinct rhizobacterial strains, Rhizobium sp. SL42 and Hydrogenophaga sp. SL48, through whole genome de novo sequencing. Isolated from root nodules of Amphicarpaea bracteata, a native legume related to soybean, they were selected to explore beneficial rhizobacteria from native plant relatives. Utilizing Illumina and Nanopore sequencers and MaSuRCA assembly, their complete genetic information was elucidated. Rhizobium sp. SL42 has a 4.06 Mbp circular chromosome and two plasmids with 60% GC content, while Hydrogenophaga sp. SL48 exhibits a 5.43 Mbp circular chromosome with 65% GC content. Genetic analysis identified them as new species, supported by ANI values (77.72% for SL42 and 83.39% for SL48) below the threshold. The genomic analysis unraveled a plethora of genes encoding diverse metabolic functions, secretion systems for substance transport, quorum sensing for coordination, and biosynthetic gene clusters suggesting the production of bioactive compounds. These functional properties contribute to plant growth stimulation, reflecting the symbiotic relationship of rhizobacteria with plants, potentially involving nitrogen fixation and growth-promoting compounds. This research contributes valuable knowledge about plant-microbe interactions and plant growth promotion by these two strains of rhizobacteria

Review of Ongoing Clinical Trials in Non–Small-Cell Lung Cancer: A Status Report for 2012 from the ClinicalTrials.gov Web Site

IntroductionClinical research in non–small-cell lung cancer (NSCLC) is a rapidly evolving field. In an effort to identify the current trends in lung cancer clinical research, we reviewed ongoing clinical trials in NSCLC listed in the ClinicalTrials.gov registry in 2012, and we also compared this data to a similar survey conducted by us in 2009.MethodsThe Web site's advanced search function was used to search for the term “non-small cell lung cancer.” The search was further refined by using the following options from the search page drop-down menu, “open studies” and “interventional.” Studies with non-NSCLC tumor histologies and pediatric studies were excluded.ResultsOf the 477 trials included in the analysis, 105 (22.0%) were phase I, 223 phase II (46.8%), and 63 phase III trials (13.2%). When compared with data from 2009, university-sponsored trials decreased in number (45.4%–34.2%; p < 0.001) whereas industry-sponsored trials remained almost the same. There was a significant increase in trials conducted exclusively outside of the United States (35.9%–48.8%; p = 0.001). The number of studies with locations in China (61, 12.8%) was second only to that in the United States (244, 51.2%). Studies reporting biomarker analysis increased significantly from 37.5% to 49.1% in 2012 (p < 0.001). Biomarker-based patient selection also increased significantly from 7.9% to 25.8% (p < 0.001). Targeted therapies were evaluated in 70.6% of phase I/II and II trials, and the most common class of targeted agent studied was epidermal growth factor receptor tyrosine kinase inhibitors (38.0%). Prespecified accrual times were observed to increase when compared with data reported in 2009, especially among industry-sponsored studies.ConclusionsOur survey identified major changes in lung cancer clinical research since 2009. Almost half of all studies registered at the ClinicalTrials.gov Web site are being conducted outside the United States, and several novel molecularly targeted agents are being evaluated in the treatment of patients with NSCLC. More importantly, we identified a threefold increase in the number of studies that perform biomarker testing to determine patient selection over the last 3 years

Layered Tablets: A Novel Oral Solid Dosage Form

Oral solid dosage forms hold a predominant position in the drug delivery system. Tablets are the most widely used and convenient dosage form. Due to their ease of manufacturing, the minimum cost of production, easy handling and storage, and better stability, tablets are most preferred. Patients who are prescribed more than one drug are in a situation to consume multiple tablets. To minimize the counts, one or more drugs are cast into layers to form a single tablet, thus called layered tablets. Layered tablets tend to improve patient compliance and reduce the cost of production by half. Layers can be of multiple drugs or the same drug at different doses or drugs with release enhancers or drugs with fillers. Layered tablets hold a greater potential with better patient outcomes as well as stay production-friendly

Knowledge and awareness of cervical cancer prevention and HPV vaccination among medical and nursing students in a tertiary care hospital

Background: This study was done to assess the level of knowledge and awareness about cervical cancer and its prevention among medical and nursing students. Methods: This descriptive cross-sectional study was conducted during 2022 in a tertiary care hospital in Chennai. The study included 407 subjects; 224 medical students, and 183 nursing students and consent was obtained from each participant prior to the study. A questionnaire survey was used to assess their knowledge on cervical cancer and its prevention. Results: Out of the 407 participants, 95.5% of the medical students and 30.6% of the nursing students knew that HPV virus causes cervical cancer. Medical students had more knowledge on risk factors. 84.38% of medical students and 43.72% of nursing students were aware that vaccine is available for the prevention of cervical cancer. Overall nursing students had limited knowledge on cervical cancer and its prevention. 51.79% of the medical students and 27.87% of the nursing students acquired their knowledge about HPV vaccine through social media. The uptake of HPV vaccine was very low among both medical and nursing students. Conclusions: The results of our study demonstrate that there is a need for creating more awareness about cervical cancer and its prevention among medical and nursing students

Plant Growth-Promoting Rhizobacteria: Context, Mechanisms of Action, and Roadmap to Commercialization of Biostimulants for Sustainable Agriculture

Microbes of the phytomicrobiome are associated with every plant tissue and, in combination with the plant form the holobiont. Plants regulate the composition and activity of their associated bacterial community carefully. These microbes provide a wide range of services and benefits to the plant; in return, the plant provides the microbial community with reduced carbon and other metabolites. Soils are generally a moist environment, rich in reduced carbon which supports extensive soil microbial communities. The rhizomicrobiome is of great importance to agriculture owing to the rich diversity of root exudates and plant cell debris that attract diverse and unique patterns of microbial colonization. Microbes of the rhizomicrobiome play key roles in nutrient acquisition and assimilation, improved soil texture, secreting, and modulating extracellular molecules such as hormones, secondary metabolites, antibiotics, and various signal compounds, all leading to enhancement of plant growth. The microbes and compounds they secrete constitute valuable biostimulants and play pivotal roles in modulating plant stress responses. Research has demonstrated that inoculating plants with plant-growth promoting rhizobacteria (PGPR) or treating plants with microbe-to-plant signal compounds can be an effective strategy to stimulate crop growth. Furthermore, these strategies can improve crop tolerance for the abiotic stresses (e.g., drought, heat, and salinity) likely to become more frequent as climate change conditions continue to develop. This discovery has resulted in multifunctional PGPR-based formulations for commercial agriculture, to minimize the use of synthetic fertilizers and agrochemicals. This review is an update about the role of PGPR in agriculture, from their collection to commercialization as low-cost commercial agricultural inputs. First, we introduce the concept and role of the phytomicrobiome and the agricultural context underlying food security in the 21st century. Next, mechanisms of plant growth promotion by PGPR are discussed, including signal exchange between plant roots and PGPR and how these relationships modulate plant abiotic stress responses via induced systemic resistance. On the application side, strategies are discussed to improve rhizosphere colonization by PGPR inoculants. The final sections of the paper describe the applications of PGPR in 21st century agriculture and the roadmap to commercialization of a PGPR-based technology

Consultant-led UK paediatric palliative care services: Professional configuration, services, funding

Objectives: To systematically gather information on the professional team members, services provided, funding sources and population served for all consultant-led specialised paediatric palliative care (SPPC) teams in the UK. Methods: Two-part online survey. Results: Survey 1: All 17 medical leads from hospital-based or hospice-based SPPC teams responded to the survey (100% response rate). Only six services met the NICE guidance for minimum SPPC team. All services reported providing symptom management, specialist nursing care, end-of-life planning and care, and supporting discharges and transfers to home or hospice for the child's final days-hours. Most services also provided care coordination (n=14), bereavement support (n=13), clinical psychology (n=10) and social work-welfare support (n=9). Thirteen had one or more posts partially or fully funded by a charity. Survey 2: Nine finance leads provided detailed resource/funding information, finding a range of statutory and charity funding sources. Only one of the National Health Service (NHS)-based services fully funded by the NHS. Conclusions: One-third of services met the minimum criteria of professional team as defined by NICE. Most services relied on charity funding to fund part or all of one professional post and only one NHS-based service received all its funding directly from the NHS

Lower dietary intake of plant protein is associated with genetic risk of diabetes-related traits in urban Asian Indian adults

The increasing prevalence of type 2 diabetes among South Asians is caused by a complex interplay between environmental and genetic factors. We aimed to examine the impact of dietary and genetic factors on metabolic traits in 1062 Asian Indians. Dietary assessment was performed using a validated semi-quantitative food frequency questionnaire. Seven single nucleotide polymorphisms (SNPs) from the Transcription factor 7-like 2 and fat mass and obesity-associated genes were used to construct two metabolic genetic risk scores (GRS): 7-SNP and 3-SNP GRSs. Both 7-SNP GRS and 3-SNP GRS were associated with a higher risk of T2D (p = 0.0000134 and 0.008, respectively). The 3-SNP GRS was associated with higher waist circumference (p = 0.010), fasting plasma glucose (FPG) (p = 0.002) and glycated haemoglobin (HbA1c) (p = 0.000066). There were significant interactions between 3-SNP GRS and protein intake (% of total energy intake) on FPG (Pinteraction = 0.011) and HbA1c (Pinteraction = 0.007), where among individuals with lower plant protein intake (1 risk allele had higher FPG (p = 0.001) and HbA1c (p = 0.00006) than individuals with ≤1 risk allele. Our findings suggest that lower plant protein intake may be a contributor to the increased ethnic susceptibility to diabetes described in Asian Indians. Randomised clinical trials with increased plant protein in the diets of this population are needed to see whether the reduction of diabetes risk occurs in individuals with prediabetes
