Purpose To evaluate and compare the clinical effectiveness of alkasite with nanofilled resin composite restorations for occlusal caries lesions in permanent molar teeth of children, at one-year follow-up. Methods In this randomized controlled clinical trial with parallel design, 38 children aged 7–13 years with occlusal caries lesions on 59 first permanent molars were randomly allocated into two groups, Group 1: Filtek™ Z350XT (nanocomposite) and Group 2: Cention N ® (alkasite resin composite). The restorations were evaluated at one year using the United States Public Health Service (USPHS) criteria. Data were analyzed using Chi-square or Fisher’s exact test. Results All restorations had either Alpha or Bravo scores at one-year follow-up. In Group 1, all restorations scored Alpha, while one restoration each (3.6%) in Group 2 scored Bravo for fracture and marginal adaptation. All restorations in both groups scored Alpha for retention, secondary caries, and post-operative sensitivity. For anatomic form, all restorations in Group 1 scored Alpha, while three (10.7%) restorations in Group 2 had Bravo scores. For marginal discolouration, three restorations in both groups scored Bravo (11.5% and 10.7%, respectively). For surface roughness, one restoration (3.8%) in Group 1 and three restorations in Group 2 (10.7%) scored Bravo. The comparative results between the two groups for all the variables in the USPHS criteria were not statistically significantly different. Conclusions The performances of the nanofilled composite and alkasite were clinically acceptable and comparable. Alkasite can be an alternative material for the restoration of occlusal caries lesions in permanent molars of children. Clinical trial registration The clinical trial was registered at Clinical Trials Registry—India (CTRI Reg no: CTRI/2020/12/029830 Dated: 15/12/2020).

Introduction: SARS CoV-2, a novel corona virus, has emerged in December 2019. The COVID-19 associated mortality is documented in elderly with co morbidities. To have better insight on this issue, the secondary bacterial infections with multi-drug- resistant bacteria in COVID-19 patients need to be studied to evaluate the impact of these infections on the outcome. Aim and objectives: To determine the proportion of secondary infections in COVID-19 patients. To study the spectrum of pathogens and antibiogram of the bacteria isolated from secondary infections in such patients. To evaluate the co-existing co-morbidities, treatment and outcome in these patients. Methodology: The retrospective study was conducted in Departments of Medicine and Microbiology, KMC hospitals Attavara and Ambedkar circle, Mangaluru, including all the hospitalized microbiologically confirmed cases of SARS CoV-2 infection. Details pertaining to the study population were collected using a structured proforma. Descriptive data were entered in the form of mean, median and proportions. The categorical values were analyzed using Chi square test. Values of p < 0.05 were considered as statistically significant. Results: Two hundred COVID-19 hospitalized patients were included. (28) out of 200 patients (14%) studied developed secondary infections. The types of secondary infections were Respiratory infections (50%), blood stream infections (17%), UTI (14%), Rhinocerebral Zygomycosis (17%). The predominant organisms were Klebsiella pneumoniae (44%), Zygomycetes (17%). The rates of antibiotic resistance in Gram negative bacilli were 33% to Cefuroxime, 25% to aminoglycosides and fluoroquinolones and 16% to carbapenems. The mortality of 42.8% was observed in patients with secondary infections. Conclusion: Close monitoring and follow up especially in high-risk group of severe COVID 19 patients is crucial for better management and outcome.

Abstract BACKGROUND: Sedative agents used in bronchoscopy require trained personnel to administer and monitor the patient. This increases the procedure cost, duration, and inpatient stay. Inhalational administration of sedative agents can be a practical solution to the issue. Dexmedetomidine in the inhalational form could give results similar to the intravenous form without significant adverse events. MATERIALS AND METHODS: The study is prospective, randomized, and double-blinded study. Patients needing bronchoscopy were randomized to receive the nebulized form of either dexmedetomidine or saline (0.9%) before bronchoscopy. The study parameters are assessed and recorded before, during, and after bronchoscopy. Data collected are analyzed using the SPSS software. DISCUSSION: The side effects limit using commonly administered sedation agents in bronchoscopy, such as midazolam, fentanyl, and dexmedetomidine. The nebulized dexmedetomidine is safe with proven efficacy when compared to the placebo. Proceduralist-administered conscious sedation reduces the overall cost and shortens inpatient stays. Attenuation of hemodynamic parameters by dexmedetomidine could be an advantage for the physician in reducing an untoward cardiac event. CONCLUSION: Dexmedetomidine in the nebulized form improves the comfort of patients during the procedure. It blunts the pressure response during bronchoscopy and could be a safer and cost-effective agent in its nebulized form for conscious sedation in bronchoscopy. The study is approved by the institutional ethics committee (IEC KMC MLR 10-2021-310).

Background Behavioural risk factors may often present during adolescence and account for 70% of premature deaths during adulthood. Excessive sedentary behaviour and screen time have become significant concerns, especially among adolescents, due to their potential negative impact on physical and mental health. Adolescents with a high screen-based sedentary time are more likely to be physically inactive, have unhealthy body structure and poor academic performance. The objective of our study is to assess the effect of multi-component modular educational intervention on screen-based sedentary time (SST) and non-screen-based Sedentary time (NSST) among adolescents. Methods Ethical approval for the study has been obtained from the institutional Ethics Committee of Kasturba Medical College in Mangalore, India. This cluster randomized control trial will be carried out in schools located in the urban area of Mangalore. Using simple randomization, the eligible schools will be randomized into intervention and control arms, each consisting of 10 clusters. A multi-component modular educational intervention will be administered to participants in the intervention group at baseline, second and fourth month. The control group will receive the standard curriculum. Both the groups will be assessed at baseline and at second month, fourth month and sixth month of follow up for SST, NSST and level of physical activity. Anthropometric measurements like height, weight, waist circumference and hip circumference will be taken at baseline and sixth month of follow up. Results A comprehensive school-based modular educational intervention can have cumulative advantages by reducing screen- and non-screen-based sedentary time, and encouraging physical activity. Similar modular teaching can be incorporated into the curriculum, which will promote healthy life-style among the adolescents.

Introduction : The Joint National Committee (JNC 7) report on Prevention, Detection, Evaluation, and Treatment of Hypertension, defined \"prehypertension,\" as individuals with a Systolic Blood Pressure (SBP) in the range of 120–139 mmHg and a (diastolic blood pressure) DBP of 80–89 mmHg. Prehypertension is directly linked with hypertension which is a precursor of CVDs. Owing to its high conversion rate to hypertension, it is important to identify individuals with blood pressures in this category and bring about lifestyle modifications in them that can prevent them from being hypertensive and from developing cardiovascular diseases later in life. Methods : This randomized controlled trial will be done among the selected pre-hypertensive adults of all genders residing in Kateel Gram panchayat, Dakshina Kannada district, Karnataka. A baseline survey will be done initially to assess the level of prehypertension among the study population. To study the effectiveness of the intervention, 142 individuals will be randomly allocated using block randomization technique to intervention and control groups. A multi-component module (educational intervention) will be developed, validated, and administered to participants in the intervention group, while the control group receives standard care. Each participant will then be followed up once in four months till the end of the study period of one year to assess for changes in SBP, DBP, WHR, BMI, stress levels, and usage of tobacco and alcohol. Ethics and dissemination : Institutional Ethics Committee approval was obtained from Kasturba Medical College in Mangalore, India.   The plans for dissemination of findings include presenting at scientific conferences and publishing in scholarly journals.

Aim: A tissue-equivalent bolus of sufficient thickness is used to overcome build up effect to the chest wall region of postmastectomy radiotherapy (PMRT) patients with tangential technique till Radiation Therapy Oncology Group (RTOG) Grade 2 (dry desquamation) skin reaction is observed. The aim of this study is to optimize surface dose delivered to chest wall in three-dimensional radiotherapy using EBT3 film. Materials and Methods: Measurements were conducted with calibrated EBT3 films with thorax phantom under \"open beam, Superflab gel (0.5 cm) and brass bolus conditions to check correlation against TPS planned doses. Eighty-two patients who received 50 Gy in 25# were randomly assigned to Group A (Superflab 0.5 cm gel bolus for first 15 fractions followed by no bolus in remaining 10 fractions), Group B or Group C (Superflab 0.5 cm gel or single layer brass bolus, respectively, till reaching RTOG Grade 2 skin toxicity). Results: Phantom measured and TPS calculated surface doses were within − 5.5%, 4.7%, and 8.6% under open beam, 0.5 cm gel, and single layer of brass bolus applications, respectively. The overall surface doses (OSD) were 80.1% ±2.9% (n = 28), 92.6% ±4.6% (n = 28), and 87.4% ±4.7% (n = 26) in Group A, B, and C, respectively. At the end of treatment, 7 out of 28; 13 out of 28; and 9 out of 26 patients developed Grade 2 skin toxicity having the OSD value of 83.0% ±1.6% (n = 7); 93.7% ±3.2% (n = 13); and 89.9% ±5.6% (n = 9) in Groups A, B, and C, respectively. At the 20th-23rd fraction, 2 out of 7; 6 out of 13; and 4 out of 9 patients in Groups A, B, and C developed a Grade 2 skin toxicity, while the remaining patients in each group developed at the end of treatment. Conclusions: Our objective to estimate the occurrence of optimal dose limit for bolus applications in PMRT could be achieved using clinical EBT3 film dosimetry. This study ensured correct dose to scar area to protect cosmetic effects. This may also serve as quality assurance on optimal dose delivery for expected local control in these patients.

NY-ESO-1 and LAGE-1 are cancer testis antigens with an ideal profile for tumor immunotherapy, combining up-regulation in many cancer types with highly restricted expression in normal tissues and sharing a common HLA-A*0201 epitope, 157–165. Here, we present data to describe the specificity and anti-tumor activity of a bifunctional ImmTAC, comprising a soluble, high-affinity T-cell receptor (TCR) specific for NY-ESO-1 157–165 fused to an anti-CD3 scFv. This reagent, ImmTAC-NYE, is shown to kill HLA-A2, antigen-positive tumor cell lines, and freshly isolated HLA-A2- and LAGE-1-positive NSCLC cells. Employing time-domain optical imaging, we demonstrate in vivo targeting of fluorescently labelled high-affinity NYESO-specific TCRs to HLA-A2-, NY-ESO-1 157–165 -positive tumors in xenografted mice. In vivo ImmTAC-NYE efficacy was tested in a tumor model in which human lymphocytes were stably co-engrafted into NSG mice harboring tumor xenografts; efficacy was observed in both tumor prevention and established tumor models using a GFP fluorescence readout. Quantitative RT-PCR was used to analyze the expression of both NY-ESO-1 and LAGE-1 antigens in 15 normal tissues, 5 cancer cell lines, 10 NSCLC, and 10 ovarian cancer samples. Overall, LAGE-1 RNA was expressed at a greater frequency and at higher levels than NY-ESO-1 in the tumor samples. These data support the clinical utility of ImmTAC-NYE as an immunotherapeutic agent for a variety of cancers.

Keywords: fractional anisotropy, diffusion tensor imaging, low backache, neuroimaging A Diffusion Tensor Imaging study to compare normative fractional anisotropy values at the lumbar spine with patients suffering from lower back pain 1.0 Introduction Lumbar disc herniation with radiculopathy is one of the most common disease caused due to nerve root compression which can lead to several functional abnormalities. ROI's using standard techniques and anatomy reference overlap sequences were drawn in the lumbar spine regions using DTI Philips extended MR fiber track software version 7.1.5.1.A 6 voxel ROI was placed on both right and left side of L3, L4 and L5 lumbar vertebrae in sagittal section and FA and ADC values were obtained as depicted in figure 1. There was no significant difference found in FA and ADC values in other nerve roots when compared with individuals with back pain to individuals without back pain. 4.0 Discussion In the present study of 40 patients (20 were patients suffering from back pain and 20 were patients who are suffering from sciatica, changes in bladder and bowel functions, numbness in the leg and decreased reflexes at the knee and ankle) were included who were referred for the MRI scans of the Lumbar spine, whole spine and dorso-lumbar spine where the L3, L4 and L5 vertebrae can be seen from which the FA and ADC values were calculated. The present study estimates the changes in the FA and ADC values in patients suffering from with and without lower back pain.Dallaudiere et al (7) et al conducted a study which showed that the mean FA and Mean Diffusivity (MD) values in lumbar nerve fibres was found different in patients with any symptomatic nerve root pain and no anatomical disco radicular conflict when comparing it to the healthy volunteers.

In the present era, mental disability is a major public health problem in the society. Many of the mental disabilities are correctable if detected early. To assess the prevalence and pattern of mental disability. Community-based cross-sectional study. One thousand subjects in all age groups were randomly selected from four villages in Udupi district, Karnataka. The study was conducted by making house-to-house visits, interviewing, and examining all the individuals in the families selected with pre-designed and pretested questionnaire. Proportions, chi-square test. The prevalence of mental disability was found to be 2.3%. The prevalence was higher among females (3.1%) than among males (1.5%). The prevalence was higher among the elderly age group and illiterates. There is ample scope for community-based rehabilitation of the mentally disabled.

The government of India launched the pulse polio immunization (PPI) programme in 1995 with the aim of eradicating poliomyelitis by the end of 2000. Despite this, 733 children with polio were reported in 2009 alone. Therefore, there is a need to understand the reason underlying such high numbers of cases after so many years of programme implementation. This study was performed to assess the knowledge of the general population about poliomyelitis and PPI and their attitude and practice towards PPI. This cross-sectional study was undertaken in two semi- urban areas of Mangalore city. Only houses in which children under five lived were included in the study. Data was collected by interviewing any adult member of the household using a pretested questionnaire. The literacy rate of study participants was 99%. Only 35(10.9%) participants knew the correct mode of transmission of polio. More than one quarter of the study population were under the misconception that polio is a curable disease. The primary source of information about PPI in majority of participants was the television (n = 192; 60%). Two-hundred and eighty eight (90%) participants knew that the purpose of PPI was to eradicate polio. Only 128 (40%) participants knew that polio drops can be given to children with mild illnesses and an identical number of participants knew that hot food stuff should not be given for at least half an hour following vaccination administration. Misconceptions such as PPI causing vaccine overdose was identified among 7 (2.2%) participants, it is a substitute for routine immunization was believed among 30 (9.4%) participants and that oral polio vaccine prevents other diseases was seen among 76 (23.7%) participants. The educational status of the participants was significantly associated with their awareness level (χ(2) =13.668, DF=6, P=0.033). This study identified a few important misconceptions associated with polio and PPI which need to be addressed by large scale awareness campaigns in order to achieve polio eradication in the near future.
