RESUMO

Cardiovascular diseases (CVDs) are a leading cause of mortality worldwide. Early detection and effective risk assessment are crucial for implementing preventive measures and improving patient outcomes for CVDs. This work presents a novel approach to CVD risk assessment using fundus images, leveraging the inherent connection between retinal microvascular changes and systemic vascular health. This study aims to develop a predictive model for the early detection of CVDs by evaluating retinal vascular parameters. This methodology integrates both handcrafted features derived through mathematical computation and retinal vascular patterns extracted by artificial intelligence (AI) models. By combining these approaches, we seek to enhance the accuracy and reliability of CVD risk prediction in individuals. The methodology integrates state-of-the-art computer vision algorithms and AI techniques in a multi-stage architecture to extract relevant features from retinal fundus images. These features encompass a range of vascular parameters, including vessel caliber, tortuosity, and branching patterns. Additionally, a deep learning (DL)-based binary classification model is incorporated to enhance predictive accuracy. A dataset comprising fundus images and comprehensive metadata from the clinical trials conducted is utilized for training and validation. The proposed approach demonstrates promising results in the early prediction of CVD risk factors. The interpretability of the approach is enhanced through visualization techniques that highlight the regions of interest within the fundus images that are contributing to the risk predictions. Furthermore, the validation conducted in the clinical trials and the performance analysis of the proposed approach shows the potential to provide early and accurate predictions. The proposed system not only aids in risk stratification but also serves as a valuable tool for identifying vascular abnormalities that may precede overt cardiovascular events. The approach has achieved an accuracy of 85% and the findings of this study underscore the feasibility and efficacy of leveraging fundus images for cardiovascular risk assessment. As a non-invasive and cost-effective modality, fundus image analysis presents a scalable solution for population-wide screening programs. This research contributes to the evolving landscape of precision medicine by providing an innovative tool for proactive cardiovascular health management. Future work will focus on refining the solution's robustness, exploring additional risk factors, and validating its performance in additional and diverse clinical settings.

RESUMO

PURPOSE: The knowledge and attitude of participants toward clinical trials (CTs) are a key determinant in successful recruitment and retention. This study aimed to evaluate knowledge and awareness-attitude among the recruited CT participants about CTs. METHODS: This was a cross-sectional face-to-face survey comprising CT participants involved in the past or currently a part of a CT during this study within the Indian Ophthalmology Clinical Trial Network (IOCTN). A previously validated questionnaire was used, and data regarding demographics, knowledge, and awareness-attitude about CTs were collected. The total awareness-attitude score was used to determine the knowledge and awareness of the participants. RESULTS: A total of 121 subjects had participated in the study who were part of ongoing trials, of which only five participants had prior experience of CTs. The majority (90%) had knowledge about CTs, whereas only 7% had confirmed signing consent forms. The total awareness-attitude score significantly varied across locations (27% for the southern zone, 53% for the central zone, and 52% for the western zone), and this was negatively associated with education. The most negative attitude (38.6%) was observed regarding adequate information sharing among participants, whereas non-disruption of their routine family life (60.7%) and financial stability (67.6%) were the top most positive attitudes revealed during their participation. The participants' pre- and post-participation attitude toward CTs revealed a positive attitude. CONCLUSION: The factors influencing a participant's knowledge and attitudes toward CTs were revealed in the study. Furthermore, the need for awareness regarding benefits of CTs to the public, participant's rights, and their voluntary power were the major highlights.

RESUMO

Purpose: Advances in patient treatment depend heavily on clinical trials (CTs). Patient volunteers for CT are tougher to recruit and retain. In order to administer CTs effectively, it is necessary to comprehend how the public views and perceives participating in them. The study assessed the perception and attitudes of patients and bystanders toward CTs in India. Methods: This was a multi-centric, cross-sectional study among patients and bystanders using a questionnaire that consisted of socio-demographic characteristics and questions on knowledge and attitude toward participation in CTs. The minimum sample size estimated for the survey was 750. Results: A total of 1260 respondents (patients and bystanders) had participated in the survey. 42% of total respondents were aware about CTs. Unawareness regarding (i) voluntary power of an individual to participate in a CT (only 47%), (ii) entitled benefits of free treatment and medical insurance during enrolment in a CT (only 47%), and (iii) only 16% of the respondents knew involvement of human subjects in CT were the major highlights among those who had prior knowledge about CTs. Education was the most pervasive factor in shaping positive perception among the respondents. Occupation was another ubiquitous factor in shaping their perception regarding CTs. Conclusion: The majority of respondents were not aware of CTs. The major concerns observed were time consumption and harmful nature of CTs that influenced their unwillingness to participate in CTs. Initiatives such as awareness campaigns and survey assessments that would result in scientifically effective health service policies would be strategic methods to enhance CT participation.

RESUMO

Introduction: The impact of the coronavirus 2 (SARS-CoV-2) pandemic and the effect of preventive health strategies on acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are largely unknown. The public health model imposed during the pandemic and the lessons learnt have implications on recommending future preventive strategies for COPD care in general and exacerbations in particular. Aim: This study endeavors to assess the role of preventive strategies of COVID-19 on exacerbation rates of COPD during the lockdown period compared to similar periods the previous year and assess the compliance to preventive strategies for COVID-19 among COPD patients. Methods: This is a hospital-based descriptive cross-sectional study at a tertiary care center. AECOPD in patients during a period spanning five months in the pre-lockdown days was compared with exacerbation rates for a similar period during the national lockdown. Results: Sixty-eight patients were recruited (mean age: 67.38) among whom 47 were males and 21 were females. There were only 7 (10.3%) reported admissions during the lockdown period of 5 months compared to 50 (73.5%) during the corresponding period pre-lockdown. Mild exacerbations reported during the lockdown period were also significantly less with only 17 (25%) against 58 (85.3%) during the pre-lockdown period. Adherence to measures such as donning of masks, hand hygiene, and social distancing was observed among COPD patients with good compliance to the health practices promulgated in the pandemic. Discussion: A significant reduction in exacerbation rates among AECOPD patients during the period of lockdown was observed compared to a similar period the year prior. Noticeable were the findings that both community-based milder exacerbations and severe exacerbations necessitating hospitalizations showed a reduction during the period of lockdown. Adaptability, compliance and acceptance to usage of masks, hand hygiene measures, and norms such as physical distancing were observed in the majority of COPD patients.

RESUMO

Purpose: The purpose of the study was to evaluate the knowledge and perception of health-care professionals (HCPs), such as doctors/surgeons, pharmacists, nurses, optometrists, and lab technicians, on clinical trials (CTs) in India. Methods: The study was a pan-Indian cross-sectional survey initiated by the Indian Ophthalmology Clinical Trial Network (IOCTN) by using a previously validated questionnaire for three months of data collection. An online survey was used to record information regarding demographics, CT knowledge, and CT perception among HCPs. Results: A total of 630 responses were recorded from HCPs: 207 doctors and surgeons, 159 pharmacists, and 264 laboratory technicians, nurses, and optometrists across India. Over 90% of HCPs had a clear knowledge on the purpose of CTs, the informed consent (IC) process, ethical approval by the Drugs Controller General of India (DCGI). About 80% and 90% were aware of confidentiality of patients, voluntariness of participation, and good clinical practice. Surprisingly, less than 50% had lesser knowledge regarding monetary incentives of CT participants (CTPs). A slightly positive perception was observed regarding the potential benefits of CTPs, compensation related to injury, and importance of obtaining IC. Less than 50% had a negative perception that monetary compensation to CTPs led to bias and deprivation of standard treatments. However, no significant difference was observed between other aspects of demographics and perception regarding CTs. Conclusion: We observed doctors and surgeons to be having the highest regarding CTs, followed by pharmacists. The survey highlighted the necessity of scheduling awareness programs among the HCPs, which would improve their misconceptions and perception of CTs while interacting with patients for CT enrollment.

RESUMO

OBJECTIVE: The study was conducted to assess the role of seminal plasma Testis Expressed Sequence (TEX)-101 as a biomarker of male infertility. STUDY DESIGN: The study was conducted on 180 men (20-50 years) with 90 having abnormal semen reports as cases and 90 with normal reports as controls in a rural tertiary care center in Southern India over two years. After the enrolment of cases and control, semen samples were cryopreserved till the desired sample size was achieved and a biochemical test for TEX-101 was run using Human Testis-expressed Protein 101 ELISA Kit. The results of TEX-101 were compared between cases and controls and correlated with various semen parameters. Statistical analysis was done using SPSS software version 22.0, a p-value < 0.05 was considered statistically significant. RESULTS: Mean ± SD age of all participants was 29.94 ± 4.91 years. Of 90 cases, 48.9% had asthenospermia, 24.4% oligoasthenospermia, 15.6% oligospermia, 11.1% azoospermia. A statistically significant difference was observed in mean values of seminal plasma TEX-101 between cases (1.45 ± 0.08 ng/mL) and controls (2.26 ± 0.18 ng/mL), p = 0.001. A significant correlation (p = 0.001) was found between seminal TEX-101, semen volume, sperm concentration, progressive motility, and morphology. The area under the Receiver Operating Characteristic curve of TEX-101 between cases and controls was 1.00 (p = 0.001), indicating TEX-101 as a potential biomarker for distinguishing men with abnormal semen parameters from those with normal semen parameters. At a cut-off value of 1.84 ng/mL, seminal plasma TEX-101 had a sensitivity, specificity, and negative and positive predictive values of 100% for male infertility prediction. CONCLUSION: Seminal TEX-101 is a potential seminal biomarker and can be used in the qualitative assessment of male factor infertility.

RESUMO

Aggregatibacter aphrophilus, formerly known as Haemophilus aphrophilus, is one member of a group of bacteria referred to as HACEK (Haemophilus, Aggregatibacter, Cardiobacterium, Eikenella, Kingella) organisms. Infections from any of the HACEK organisms typically lead to very poor outcomes and can be difficult to manage, especially when complicated by intracranial hemorrhage (ICH). HACEK organisms can also be difficult to grow on blood cultures, and A. aphrophilus is rarely seen, if at all. Traditionally, most laboratories follow an extended incubation protocol of 14 to 21 days to aid the growth of HACEK bacteria. Herein we report a case of infective endocarditis where A. aphrophilus resulted on blood culture in three days, in a patient with a right shoulder abscess, complicated by septic embolization leading to ICH. We explore a potential link between the prompt growth of A. aphrophilus on blood culture and the presence of the right shoulder abscess.

RESUMO

There is a paucity of literature on neuropsychological functions in youth with obsessive-compulsive disorder (OCD). Most studies have small sample sizes and have yielded inconsistent results. A recent meta-analysis failed to identify any significant impairments. We studied neuropsychological functions (attention, verbal fluency, working memory, set-shifting, response inhibition, planning and visuospatial abilities) in a large sample of youth with OCD (n = 97) in comparison with controls who did not have OCD (n = 50). After controlling for the confounding effects (age, sex, severity of depression and anxiety, presence of comorbid attention-deficit hyperactivity disorder, any tic disorder, number of comorbidities, and non-verbal intelligence measured by the standard progressive matrices), the youth with OCD significantly underperformed with large effect sizes compared to controls, only on the test of 'behavioral reversal', measured by the Object Alternation Test (trials to reach criterion p < 0.001, Cohen's d = 1.49; perseverative errors p < 0.001, Cohen's d = 1.31). Patients also underperformed on a task of planning, but it was statistically insignificant. Certain comorbid disorders, antipsychotic use and age of onset did not influence neuropsychological performance significantly. Our study demonstrates that youth with OCD may have impaired 'set-shifting' in the form of 'behavioral reversal' and possibly planning, findings broadly consistent with the literature in adults and with the fronto-striatal model of OCD. It is possible that youth may accumulate more neuropsychological impairments over a period, as the illness continues into adulthood.

RESUMO

AIM: Circular RNAs (circRNA) are endogenous non-coding RNA molecules with a stable circular conformation. Growing evidence from recent experiments reveals that dysregulations and abnormal expressions of circRNAs are correlated with complex diseases. Therefore, identifying the causal circRNAs behind diseases is invaluable in explaining the disease pathogenesis. Since biological experiments are difficult, slow-progressing, and prohibitively expensive, computational approaches are necessary for identifying the relationships between circRNAs and diseases. METHODS: We propose an ensemble method called AE-RF, based on a deep autoencoder and random forest classifier, to predict potential circRNA-disease associations. The method first integrates circRNA and disease similarities to construct features. The integrated features are sent to the deep autoencoder, to extract hidden biological patterns. With the extracted deep features, the random forest classifier is trained for association prediction. RESULTS AND DISCUSSION: AE-RF achieved AUC scores of 0.9486 and 0.9522, in fivefold and tenfold cross-validation experiments, respectively. We conducted case studies on the top-most predicted results and three common human cancers. We compared the method with state-of-the-art classifiers and related methods. The experimental results and case studies demonstrate the prediction power of the model, and it outperforms previous methods with high degree of robustness. Training the classifier with the unique features retrieved by the autoencoder enhanced the model's predictive performance. The top predicted circRNAs are promising candidates for further biological tests.

RESUMO

BACKGROUND: Tooth avulsion is considered as a severe form of dental trauma, causing damage to the periodontium. Hence, the preservation of healthy periodontal ligament (PDL) cells in the storage medium are pivotal for the success of replantation. AIM AND OBJECTIVE: The aim of this study is to assess the viability of human PDL cells in black tea, lime juice, and passion fruit concentrate. METHODS: Human periodontal cells were cultured and stored in three experimental media - black tea, lime juice, and passion fruit concentrate and subjected to 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay for 1 h and the cell viability was determined. Mean and standard deviation were statistically analyzed using one-way analysis of variance to identify the significant groups. RESULTS: The human PDL cells showed 100% viability in lime juice and passion fruit concentrate, followed by 98% viability in black tea. CONCLUSION: Black tea, lime juice, and passion fruit concentrate can be used effectively as storage media for maintaining PDL cells viability in avulsed teeth, with 100% viability exhibited by lime juice and passion fruit concentrate.

RESUMO

Circular RNAs (circRNA) are a special kind of covalently closed single-stranded RNA molecules. They have been shown to control and coordinate various biological processes. Recent researches show that circRNAs are closely associated with numerous chronic human diseases. Identification of circRNA-disease associations will contribute towards diagnosing the pathogenesis of diseases. Experimental methods for finding the relation between the diseases and their causal circRNAs are difficult and time-consuming. So computational methods are of critical need for predicting the associations between circRNAs and various human diseases. In this study, we propose an ensemble approach AE-DNN, which relies on autoencoder and deep neural networks to predict new circRNA-disease relationships. We utilized circRNA sequence similarity, disease semantic similarity, and Gaussian interaction profile kernel similarities of circRNAs and diseases for feature construction. The constructed features are fed to a deep autoencoder, and the extracted compact, high-level features are fed to the deep neural network for association prediction. We conducted 5-fold and 10-fold cross-validation experiments to assess the performance; AE-DNN could achieve AUC scores of 0.9392 and 0.9431, respectively. Experimental results and case studies indicate the robustness of our model in circRNA-disease association prediction.

RESUMO

Identifying the cause-and-effect mechanism behind the drug-disease associations is a challenging task. Recent studies indicate that microRNAs (miRNAs) play critical roles in human diseases. Targeting specific miRNAs with drugs to treat diseases provides a new aspect for drug repositioning. Drug repositioning provides a way to identify new clinical applications for approved drugs. Drug discovery is expensive and complicated. Therefore, computational methods are necessary for predicting the potential associations between drugs and diseases based on the target miRNAs. Our approach bilateral-inductive matrix completion (BIMC) performed two rounds of inductive matrix completion algorithm, one on the drug-miRNA and another on the miRNA-disease, association matrices, and integrated the results for predicting the drug-disease relationships through the target miRNAs. The fundamental idea of inductive matrix completion (IMC) is to fill the unknown entries of the association matrices by utilizing existing associations and side information. In our study, the integrated similarities of drugs, miRNAs, and diseases were utilized as side information. Our method predicts drug-miRNA and miRNA-disease associations, as intermediate results. To estimate the performance of our approach, we conducted leave-one-out cross-validation (LOOCV) experiments. The method could achieve AUC scores of 0.792, 0.759, and 0.791 in drug-disease, drug-miRNA, and miRNA-diseases association predictions. The results and case studies indicate the prediction ability of our method, and it is superior to previous models with high robustness. The proposed approach predicts new drug-disease relationships and the causal miRNAs. The top predicted relationships are the promising candidates, and they are released for further biological tests.

RESUMO

BACKGROUND: Obsessive-compulsive disorder (OCD) is a common psychiatric illness in children and adolescents. Till date, the sample sizes in the Indian studies have been relatively small. METHODOLOGY: The present study is a retrospective chart review of a large sample of children and adolescents diagnosed with OCD in a tertiary care center. OBJECTIVES: The objectives of this study were to characterize the clinical profile and to evaluate outcome of OCD in children and adolescents. RESULTS: Fear of contamination and washing/cleaning compulsions were the most common presenting symptoms. Most of the patients were male with two-thirds having a comorbid disorder. Major depressive disorder was the most common comorbid disorder. The rates of attention deficit hyperactivity disorder, disruptive behavioral disorders, and tic disorders were low when compared to Western studies. One-third of the patients received adequate trial of serotonin reuptake inhibitors and 36% received cognitive behavior therapy. Fifty-four percent of patients had a poor outcome with hospitalization, longer duration of illness, earlier onset of OC symptoms, and family history of OCD being the predictors of poor outcome. CONCLUSION: The present study of a large sample of patients with juvenile OCD highlights the low rate of comorbid disruptive behavior disorders as reported in the earlier Indian studies and a favorable short-term outcome in approximately 56% of the patients.

RESUMO

BACKGROUND AND OBJECTIVE: Clinical decision rules have reduced use of computed tomography (CT) to evaluate minor pediatric head injury in pediatric emergency departments (EDs). CT use remains high in community EDs, where the majority of children seek medical care. We sought to reduce the rate of CT scans used to evaluate pediatric head injury from 29% to 20% in a community ED. METHODS: We evaluated a quality improvement (QI) project in a community ED aimed at decreasing the use of head CT scans in children by implementing a validated head trauma prediction rule for traumatic brain injury. A multidisciplinary team identified key drivers of CT use and implemented decision aids to improve the use of prediction rules. The team identified and mitigated barriers. An affiliated children's hospital offered Maintenance of Certification credit and QI coaching to participants. We used statistical process control charts to evaluate the effect of the intervention on monthly CT scan rates and performed a Wald test of equivalence to compare preintervention and postintervention CT scan proportions. RESULTS: The baseline period (February 2013-July 2014) included 695 patients with a CT scan rate of 29.2% (95% confidence interval, 25.8%-32.6%). The postintervention period (August 2014-October 2015) included 651 patients with a CT scan rate of 17.4% (95% confidence interval, 14.5%-20.2%, P < .01). Barriers included targeting providers with variable pediatric experience and parental imaging expectations. CONCLUSIONS: We demonstrate that a Maintenance of Certification QI project sponsored by a children's hospital can facilitate evidence-based pediatric care and decrease the rate of unnecessary CT use in a community setting.

RESUMO

PURPOSE: Pain is a common but understudied quality of life concern in systemic sclerosis (SSc). This investigation sought to describe patient-reported pain during the early phase of the disease and to examine potential predictors of this over time. METHODS: A prospective cohort (N = 316) of patients with early-disease SSc from the Genetics versus ENvironment In Scleroderma Outcome Study (GENISOS) were followed for 3 years. Multilevel modeling was used to describe longitudinal changes in pain and the extent to which pain variance was explained by disease type, emotional health, perceived physical health, health worry, and social support. RESULTS: Patient-reported pain remained relatively stable, with slight improvement over time. More severe disease type was associated with worse initial pain, but the association was reduced to nonsignificance after accounting for the psychosocial variables. Better emotional health and perceived physical health were associated with lower initial pain. There were marginal interactive effects for perceived physical health and social support such that initial perceptions of poorer physical health, and higher social support, were predictive of greater improvements in pain over time. CONCLUSIONS: These data suggest that emotional health, perceived physical health, and social support are more relevant to longitudinal SSc pain than disease severity and that perceived physical health and social support may impact pain trajectories. Researchers and rheumatology health professionals should consider these factors in comprehensive pain models and pain management protocols.

RESUMO

BACKGROUND: Gloriosa superba, well known as the glory lily or superb lily, is a tropical climbing plant that features an exotic red flower. The plant is poisonous because of high concentrations of colchicine in all parts of the plant. It is commercially grown for use in Ayurveda medicine and as a cash crop for extracting colchicine in India and Africa. It is a wild plant in Sri Lanka and commercial cultivation is rare. Accidental and suicidal poisonings with Gloriosa tubers are well known and reported. There are no case reports of poisoning by Gloriosa seeds in Sri Lanka. Google and PubMed searches showed no reported cases of poisoning with seeds or their use with homicidal intent in other parts of the world. CASE PRESENTATION: A 27-year-old man was brought to hospital with profuse vomiting and diarrhea after drinking coriander tea, which is a common traditional treatment for common cold. The family members suspected poisoning by Gloriosa because they had seeds at home and the victim's sister-in-law who had made the herbal tea went missing from home. They were able to identify Gloriosa seeds, which looked similar to coriander, in the pot. The patient developed shock and respiratory distress and needed ventilation and intensive care. He also developed mild renal impairment, and thrombocytopenia. He developed massive generalized alopecia while recovering from acute illness. Full recovery was achieved after 15 days of hospital care. CONCLUSIONS: There are many poisonous plants in Asian countries. This case highlights the possibility of accidental or intentional use of Gloriosa seeds or its extracts to cause potentially fatal poisoning. It would be difficult to identify Gloriosa as the cause of poisoning without any background information because of multiple complications that can mimic a systemic infection. This case is a good example of the use of plants as biological weapons.

RESUMO

We report results from the first search for ν_{µ}→ν_{e} transitions by the NOvA experiment. In an exposure equivalent to 2.74×10^{20} protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99±0.11(syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07±0.14(syst). The 3.3σ excess of events observed in the primary analysis disfavors 0.1π<δ_{CP}<0.5π in the inverted mass hierarchy at the 90% C.L.

RESUMO

OBJECTIVE: Despite being a common problem in systemic sclerosis (SSc; scleroderma), the extant literature on pain has primarily focused on biomedical correlates, or bivariate relationships with a few psychological characteristics. There is a need to investigate the more heuristic biopsychosocial model, which incorporates the simultaneous contributions of medical, psychological, and social variables in understanding pain. METHODS: Patients with SSc (n = 333) received clinical examinations and completed self-report surveys at enrollment in the Genetics versus Environment in Scleroderma Outcome Study. Latent profile analysis was used to derive biopsychosocial profiles of patients using skin thickening, percent predicted forced vital lung capacity, perceived physical health, health worry, mental health, and social support. The profiles were examined in relation to pain and pain medication usage. RESULTS: A 3-profile solution provided the best fit to the data. Based on the biopsychosocial indicators, the profiles were characterized as managing (n = 217), resilient (n = 86), and distressed (n = 30). Between-group differences for pain emerged, with the distressed group, whose disease was less severe than the resilient group, reporting the highest pain and the greatest utilization of pain medication. CONCLUSION: Clinicians should consider biopsychosocial characteristics as contributing factors to the experience of pain in patients with SSc. Patients who are similar to those in the distressed profile may be at an increased risk for pain and would likely benefit from a referral to a behavioral health or other ancillary service provider for pain management, rather than relying solely on pharmacologic therapies.

RESUMO

BACKGROUND: Oxidative stress (OS) generated by hyperglycemia, is one of the major focuses of recent research related to diabetes mellitus. Studying associations between hyperglycemia, OS and atherogenic dyslipidemia (AD) is therefore important. MATERIALS AND METHODS: Plasma was obtained form a total of 52 subjects with newly diagnosed Type 2 diabetes mellitus (T2DM) and 52 healthy controls to study associations between hyperglycemia, lipid risk factors for atherogenicity and malondialdehyde (MDA), a lipid peroxidation product. Ferric reducing ability of plasma (FRAP) was evaluated as a measure of total antioxidant capacity (TAC). RESULTS: Diabetic patients had significantly higher (P < 0.05) plasma triglycerides (TG)), very-low-density lipoprotein cholesterol (VLDL-C), TG to high-density lipoprotein cholesterol ratio (TG/HDL-C), atherogenic index (AI), and MDA. Whereas FRAP levels were depleted significantly in the patients compared to that of controls (P = 0.000). Pearson correlation analyses showed MDA correlates significantly with Fasting blood sugar (r = 0.39, P = 0.004), TG/HDL-C (r = 0.45, P = 0.001), and AI (r = 0.40, P = 0.003), and a significant negative correlation with LDL-C (r = -0.33, P = 0.019) which was lost upon nullifying the effect of FBS by partial correlation analysis (r = -0.28, P = 0.050). Receiver operating curve (ROC) analysis showed high Area under curve for TG/HDL-C and AI (0.62; P = 0.03). CONCLUSION: Hyperglycemia of diabetes is associated with elevated levels of plasma MDA. This study suggests that TG/HDL-C and AI may be particularly useful as atherogenic risk predictors in newly diagnosed patients with T2DM.

RESUMO

Coastal temperature is an important indicator of water quality, particularly in regions where delicate ecosystems sensitive to water temperature are present. Remote sensing methods are highly reliable for assessing the thermal dispersion. The plume dispersion from the thermal outfall of the nuclear power plant at Kalpakkam, on the southeast coast of India, was investigated from March to December 2011 using thermal infrared images along with field measurements. The absolute temperature as provided by the thermal infrared (TIR) images is used in the Arc GIS environment for generating a spatial pattern of the plume movement. Good correlation of the temperature measured by the TIR camera with the field data (r(2) = 0.89) make it a reliable method for the thermal monitoring of the power plant effluents. The study portrays that the remote sensing technique provides an effective means of monitoring the thermal distribution pattern in coastal waters.
