A novel framework for predicting patients at risk of readmission
Uncertainty in decision-making for patients’ risk of re-admission arises due to non-uniform data and lack of knowledge in health system variables. The knowledge of the impact of risk factors will provide clinicians better decision-making and in reducing the number of patients admitted to the hospital. Traditional approaches are not capable to account for the uncertain nature of risk of hospital re-admissions. More problems arise due to large amount of uncertain information. Patients can be at high, medium or low risk of re-admission, and these strata have ill-defined boundaries. We believe that our model that adapts fuzzy regression method will start a novel approach to handle uncertain data, uncertain relationships between health system variables and the risk of re-admission. Because of nature of ill-defined boundaries of risk bands, this approach does allow the clinicians to target individuals at boundaries. Targeting individuals at boundaries and providing them proper care may provide some ability to move patients from high risk to low risk band. In developing this algorithm, we aimed to help potential users to assess the patients for various risk score thresholds and avoid readmission of high risk patients with proper interventions. A model for predicting patients at high risk of re-admission will enable interventions to be targeted before costs have been incurred and health status have deteriorated. A risk score cut off level would flag patients and result in net savings where intervention costs are much higher per patient. Preventing hospital re-admissions is important for patients, and our algorithm may also impact hospital income
Genetic Algorithm based Application Research in Computer Network Security Evaluation
Network security is a complex systematic job. Current safety methods available are having some shortcomings like feasibility , man made interference, smaller application scope and so on. The imitation results shows that using the established evaluation model for network security assessment is simple, also eliminate the interference of human factors and can quickly find the correct results of the assessment. This article provides new ideas and methods to work for a wide-ranging evaluation of computer network security condition, specially with a certain reference value to predict and control of network security issues in the futur
A fuzzy approach for unequal workers-task assignment with heptagonal fuzzy numbers
The problem of assigning n tasks to n workers with minimum assignment cost often arises in many practical applications. In real life, the cost of assignment may not be certain and also the number of tasks may not be always equal to the number of workers and an unbalanced situation may arise often. In this paper, the representation of the Heptagonal fuzzy number(HFN) and its arithmetic operations are reviewed and a fuzzy approach called as fuzzy row penalty method is extended within the context of Heptagonal fuzzy numbers to deal with the unbalanced Fuzzy Assignment Problems. The cost of assignment is represented by Heptagonal fuzzy numbers which are capable of incorporating the degree of satisfaction about the assignment cost. So the use of HFN is more suitable. The proposed method overcomes the limitations of existing methods and it is illustrated through numerical example
Allosteric collaboration between elongation factor G and the ribosomal L1 stalk directs tRNA movements during translation
Determining the mechanism by which transfer RNAs (tRNAs) rapidly and
precisely transit through the ribosomal A, P and E sites during translation
remains a major goal in the study of protein synthesis. Here, we report the
real-time dynamics of the L1 stalk, a structural element of the large ribosomal
subunit that is implicated in directing tRNA movements during translation.
Within pre-translocation ribosomal complexes, the L1 stalk exists in a dynamic
equilibrium between open and closed conformations. Binding of elongation factor
G (EF-G) shifts this equilibrium towards the closed conformation through one of
at least two distinct kinetic mechanisms, where the identity of the P-site tRNA
dictates the kinetic route that is taken. Within post-translocation complexes,
L1 stalk dynamics are dependent on the presence and identity of the E-site
tRNA. Collectively, our data demonstrate that EF-G and the L1 stalk
allosterically collaborate to direct tRNA translocation from the P to the E
sites, and suggest a model for the release of E-site tRNA
Awareness about inhalation general anaesthetics among dental students
Introduction: General anesthesia is a state of medically induced coma or unconsciousness. General
anaesthetics are drugs that render a patient unresponsive and unconscious, so that the patient is
unaware of surgery and does not move or feel pain while it's being carried out. The anaesthetic agent
is administered through an intravenous line or the anaesthetic agent may be inhaled through a
breathing mask or tube. Inhalation anesthetics are also known to be found in two forms, gaseous
anesthetics and the volatile anaesthetics. The volatile anesthetics are liquids at room temperature and
need vapourizers to make it suitable for the inhalation purposes.
Aim:The present study aimed to assess the knowledge and awareness on inhalation anaesthesia
among dental students.
Materials and Methods: The present study is an online based survey conducted among the dental
students.The participants were from 1st, 2nd, 3rd and 4th years of BDS. Questionnaires were
prepared and distributed among dental students through an online link from the survey planet.
Results and Discussion: About 62% of the students were well aware of inhalation general
anaesthesia. 55% of the students were aware of nitrous oxide as inhalation general anesthetics. From
the results of the survey it is clear that most of the dental students were well aware of inhalation
general anaesthesia and also had proper knowledge about its complications
A Brief Synopsis of Monoclonal Antibody for the Treatment of Various Groups of Diseases
Monoclonal antibodies (mAbs) are increasingly being prescribed to patients and investigated in the field of medicine and research. This class of medication is unique due to its ability to be engineered into targeting a specific receptor. Numerous studies and reviews have reported the efficacy, potency, and clinical usage of mAbs in the treatment of a variety of diseases ranging from autoimmune disorders to malignant cancers. However, very few publications classify and provide a brief synopsis of mAbs that includes their pharmacological profiles, mechanisms of action, uses, and side effects in a concise manner. Therefore, this review aims to classify the current mAbs drugs used in clinical practice according to system diseases by providing a brief summary for each of them. For example, regarding cardiovascular disorders, mAbs such as Abciximab, Bevacizumab, and Digoxin Immune Fab will be reviewed. Denosumab, used to treat musculoskeletal disorders, will be also discussed. In addition, mAbs such as Adalimumab, Eculizumab, Natalizumab used in autoimmune disorders and Alemtuzumab, Trastuzumab, Cetuximab, and Rituximab that are prescribed for tumors will be reviewed. Finally, we shall discuss two mAbs that are IL-6 antagonists, Tocilizumab and Siltuximab, which are in ongoing clinical trials as potential treatments of COVID-19. The mAbs have profound benefits against chronic and malignant conditions, and the overall purpose of this review is to illustrate the basic pharmacological profiles of mAbs that physicians may find useful in establishing their management protocols
A Hospital-based Observational Study of Type 2 Diabetic Subjects from India
Aim: The aim of this study was to describe the profile of the subjects with type 2 diabetes mellitus (T2DM) to obtain aclear picture from Western India, that would help in management of diabetes. Methods: An observational study wasconducted with newly diagnosed 622 type 2 diabetic subjects attending Dept. of Diabetology, All India Institute ofDiabetes and Research and Yash Diabetes Specialties Centre (Swasthya), Ahmedabad during the period from August 2006 to January 31, 2009. Subjects completed an interviewer-administered comprehensive questionnaire, which included variables such as sociodemographic presenting symptoms, risk profile (hypertension, obesity, dyslipidemia and glycemic status), family history of diabetes, physical activity and behavioral profile. Blood pressure, body mass index (BMI), glycosylated hemoglobin (HbA1c) and fasting lipid profile were measured. Descriptive and bivariate analyses were carried out using SPSS version 11.5. Results: A total of 622 T2DM cases with mean age (years) 47.7 ± 10.9 were studied. Of these, 384 (62%) were male. The majority of T2DM subjects were obese (68%) and 67% had positive family history of diabetes. Renal dysfunctions and vision impairment were found in 10% (62/622) and 9% (57/622), respectively in T2DM subjects. The mean HbA1c level was 9.02% ± 1.67 and good glycemic control (HbA1c level <7%) was achieved only in 7.4% T2DM subjects. The Chi-square (χ2) analysis showed that higher BMI (≥25 kg/m2) is significantly associated with hypertension among T2DM subjects (p < 0.01). There were statistically significant differences between male and female study subjects with respect to mean age, BMI, waist and hip circumference and mean low-density lipoprotein (LDL) level (p < 0.05). Conclusions: The present study revealed that obesity, family history of diabetes, dyslipidemia, uncontrolled glycemic status, sedentary lifestyles and hypertension were more prevalent in T2DM subjects. Hence, the overall risk profile was very poor and needs improvement. The characterization of this risk profile will contribute in defining more effective and specific strategies for screening and controlling T2DM in Western India

A Hospital-based Observational Study of Type 2 Diabetic Subjects from Gujarat, India
The aim of this observational study was to describe the profile of subjects with type 2 diabetes mellitus from Gujarat, India. The study was performed with newly-diagnosed 622 type 2 diabetic subjects who attended the Department of Diabetology, All India Institute of Diabetes and Research and Yash Diabetes Specialties Centre (Swasthya), Ahmedabad, during August 2006–January 2009. The subjects completed an interviewer-administered questionnaire. The questionnaire included variables, such as sociodemographic factors, presenting symptoms, risk profile (hypertension, obesity, dyslipidaemia, and glycaemic status), family history of diabetes, physical activity, and behavioural profile. Blood pressure, body mass index (BMI), glycosylated haemoglobin levels, and fasting lipid profile were measured. Descriptive and bivariate analyses were carried out using the SPSS software (version 11.5). In total, 622 type 2 diabetes mellitus (T2DM) cases with mean age of 47.7±10.9 years were studied. Of the 622 subjects, 384 (62%) were male. The majority (68%) of the T2DM subjects were obese, and 67% had a positive family history of diabetes. Renal dysfunctions and vision impairment were, respectively, found in 10% (n=62) and 9% (n=57) of the 622 T2DM subjects. The mean HbA1c level was 9.02±1.67%, and good glycaemic control (HbA1c level <7%) was achieved only in 7.4% of the T2DM subjects. Results of chi-square analysis showed that higher BMI (≥25 kg/m2) was significantly associated with hypertension among the T2DM subjects (p<0.01). There were significant differences (p<0.05) between male and female subjects with respect to mean age, BMI, waist and hip-circumference, and mean low-density lipoprotein (LDL) level. The results revealed that many factors, such as obesity, fami-ly history of diabetes, dyslipidaemia, uncontrolled glycaemic status, sedentary lifestyles, and hypertension were prevalent among the T2DM subjects. The characterization of this risk profile will contribute to designing more effective and specific strategies for screening and controlling T2DM in Gujarat, India
To Compare the Efficacy of Oral Deflazacort, Oral Prednisolone and Inhaled Budesonide in the Treatment of Salbutamol Refractory Acute Asthma in Children
Abstract
Background: A 22-month open-label randomized comparative study was conducted at tertiary care centre attached to medical college in metropolitan city in Maharashtra from Dec 2011 to Oct 2013, aiming to compare the effectiveness of three corticosteroid treatments - oral deflazacort, oral prednisolone, and inhaled budesonide in managing salbutamol-refractory asthma in children aged 1-14 years.
Methods: 90 afebrile children were equally allocated to the different treatment arms. Treatment arm A received oral Deflazacort (1mg/kg/day alternate day), treatment arm B received oral prednisolone (1mg/kg/day), and treatment arm C received budesonide inhaler (100 mcg/puff twice a day) for seven days, along with salbutamol inhalations twice a day. The primary outcome measured was the change in FEV1 and PEFR as a percentage of the predicted value from baseline, and secondary outcomes included changes in FVC, wheeze frequency, VCD, and FEV1/FVC.
Results: Wheeze varied across treatment arms on day 3 (A: 16.3%, B: 26.7%, C: 70.0%), day 7 (A: 10.0%, B: 0.0%, C: 10.0%), and day 28 (A: 16.7%, B: 0.0%, C: 16.7%). Mean PEFR values on days 1, 3, 7, and 28 were 140.67, 180, 202.67, 216.67 for Treatment Arm A; 141.43, 190, 203, 221 for Treatment Arm B; and 151.00, 179.33, 187.33, 202.00 for Treatment Arm C, respectively. FEV1 and FEV1/FVC scores showed no significant differences across the three treatment arms.
Conclusion: In treating salbutamol-refractory asthma in children, all three medications displayed comparable efficacy, aiding clinicians in treatment selection and improving outcomes. Future research should prioritize long-term effects and safety for optimal management
