Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC
Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe

Knowledge and attitude of medical professionals towards emergency management of avulsed tooth in a teaching medical hospital, Khammam Town, South India
Introduction: Injury to both the primary and permanent dentitions and their supporting structures is one of the most common problems. Avulsion of permanent tooth is one of the serious dental injuries and a prompt and correct emergency management is very important for prognosis. Studies evaluating medical professionals′ knowledge about tooth avulsion and its management are rare. Aim: To assess the knowledge and attitude of medical professionals working in a teaching medical hospital in Khammam Town toward management of an avulsed tooth. Materials and Methods: A cross-sectional questionnaire-based study was conducted with a sample of 192 medical professionals including teaching staff, postgraduates, and house surgeons. A standard self-administered questionnaire was used for data collection, which was done over a period of 1-month. Chi-square test was used for data analysis with a P < 0.05 considered to be statistically significant. Results: Among the study participants 64% were aware of the meaning of avulsed tooth. About 54% of respondents preferred saline as the best storage medium to store the tooth in case professional care is not possible immediately. There was varied opinion regarding the replantation time. In this study, 41% of the participants felt 45 min as the ideal time for replantation. Conclusion: Most of the participants showed a fair knowledge on the emergency management of an avulsed tooth and their dilemma pertaining to some aspects of this procedure that can be solved by providing required awareness and knowledge
Assessment of psychiatric morbidity among health-care students in a teaching hospital, Telangana state: A cross-sectional questionnaire-based study
Introduction: Professional education can be a stressful experience for health-care students and may impact negatively on emotional well-being and academic performance which leads to psychiatric morbidity. The aim of this study is to assess the prevalence of psychiatric morbidity among the professional health-care students. Materials and Methods: A cross-sectional study was conducted among professional health-care students in a tertiary care teaching hospital of Telangana state. The information regarding demographic data, academic achievements, and positive and negative events in the recent past was collected using semi-structured pro forma, and the General Health Questionnaire (GHQ)-28 is used to assess the psychiatric morbidity. Descriptive analysis and Pearson's correlation analysis were done to analyze the data. Results: A total of 836 students participated in the study, and the overall mean GHQ total score in the study population was 26.8, which is above the cutoff (24) score. The prevalence of psychiatric morbidity among study population is about 58.7%. Academic achievement and negative events in the recent past had effect on psychological morbidity and showed high GHQ scores among study population which was found to be statistically significant. Conclusion: The poor academic performance and negative events had a strong impact on psychological morbidity of students. The higher level of psychological morbidity warrants need for intervention such as social and psychological support to improve the quality of life for the health-care students. Further, a creation of positive academic environment as a teamwork of faculty, administration, educational experts, and students helps to develop psychological healthy dental and medical professionals who can perform better in a coming future
Evaluation of preparedness for medical emergencies among dental practitioners in Khammam town: A cross-sectional study

The nutritional knowledge on dietary recommendations was similar in both females (88.58%), and males (87.63%) which was not statistically significant (P = 0.5660) Postgraduates had more nutritional knowledge than undergraduates. Conclusion: It is learnt that males and females had similar nutritional knowledge; however, postgraduate students had more nutritional knowledge compared to undergraduates irrespective of the gender, and there is a need to improve the nutritional knowledge of undergraduate students
Perceived Levels of Supportive Care Needs of the Patients with Oral Cancer in a Metropolitan City in South India – A Cross-Sectional Questionnaire-Based Study
Introduction: The patients with cancer experience a range of challenges that can be physical, mental, and psychological. Hence, proper supportive care needs should be provided to the patients with oral cancer during the postoperative period, which can have a great impact on them and their family caregivers. Aim: To assess the perceived levels of supportive care needs, namely psychological, interpersonal communication, patient support, health information, and physical needs, of the patients with oral cancer in a metropolitan city. Materials and Methods: A cross-sectional study was conducted. One hundred and twenty patients were recruited from various cancer hospitals’ inpatient wards in the city of Hyderabad. A questionnaire was used to assess the patients’ needs, including the Karnofsky’s Performance Status Index and Cancer Needs Questionnaire Short Form. Descriptive statistics were calculated. Regression analysis was performed to find the predictive factors of various needs domains of the patients, and P < 0.05 was considered statistically significant. Results: In general, the patients reported the highest level of supportive care needs in the “Psychological” domain among six needs domains, followed by interpersonal communication needs, patient support needs, health information needs, and physical needs. Factors significantly related to those supportive care needs across six domains were stage of the cancer when admitted, past treatment underwent, occupation, location of the cancer, duration of the treatment, and undergoing problems during the treatment. Conclusion: Needs that were considered to be more important by the patients were the psychological needs and interpersonal communication needs, especially in the period within which they are being treated and when undergoing tests to determine the stage of the cancer. Routine screening for psychological and physical distress should become a first step in the assessment of the psychosocial needs of people receiving inpatient treatment for the cancer
Assessment of attitude toward community service among dental students of Tertiary Care Teaching Hospital in South India
Introduction: The dental health care providers and their community service in any nation play a pivotal role in bridging the gap between the oral health care and social service system. Understanding that there is a shortage and disparity in the oral health services provided, a greater emphasis on its awareness and education is the present need; thus, the aim of the study is to assess the attitude toward community service among dental students. Methodology: A cross-sectional questionnaire-based study was conducted among undergraduate dental students who were present on the day of study, and their attitude toward community service was assessed using a standardized Community Service Attitude Scale which consists of eight domains. Data were analyzed using descriptive statistics, Chi-square test, and ANOVA. The level of significance was set at P < 0.05. Results: The total participants included were 171. The levels of attitude toward community service among the study participants based on year (P = 0.0492), gender (P = 0.00482), and voluntary activity (P = 0.042) were found to be statistically significant. Conclusion: The attitude toward community service is influenced by gender and year of study. Hence, any practical training program with regard to service learning in their undergraduate curriculum would highly contribute to influence their attitude toward community service
