    Cassandra is an open source distributed database management system is designed to handle large amounts of data across many commodity servers, provides a high availability with no single point of failure. Cassandra will be offering the robust support for clusters spanning multiple data centers with asynchronous masterless replica which allow low latency operations for all the clients. N oSQL data stores target the unstructured data, which nature has dynamic and a key focus area for "Big Data" research. New generation data can prove costly and also unpractical to administer with databases SQL, due to lack of structure, high scalability and needs for the elasticity. N oSQL data stores such as MongoDB and Cassandra provide a desirable platform for fast and efficient for data queries. The Hadoop Distributed File System is one of many different components and projects contained within the community Hadoop ecosystem. The Apache Hadoop project defines Had oop - DFS as "the primary storage system which is used by Hadoop applications" that enables "reliable, extremely rapid computations". This paper was providing high - level overview of how Hadoop - styled analytics (MapReduce, Pig, Mahout and Hive) can be run on data contained in Apache Cassandra wit hout the need for Hadoop - DFS

    Background: Psychotropic drugs have had a remarkable impact in psychiatric practice. The continuous monitoring of prescription and drug utilization studies may help to identify the problem involved in therapeutic decision and promote rational prescribing. Very few studies from India have evaluated the prescription pattern of Psychiatrists. Present study was undertaken to analyze the prescription pattern and drug used in psychiatric Out Patients of private practitioners of Central India.Methods: One thousand prescriptions were collected by undergraduate students from chemist and analysed. Study parameter like demographic profile of patients viz. age, sex, diagnosis were recorded. Basic drug indicators, the prescribing pattern of antipsychotics and other categories of drugs were also recorded. The most common and, top brands of anti psychotics were analyzed .Inappropriate prescription if any were recorded and analyzed further.Result: The most common psychotropic drugs were anti-anxiety in 361(36.1%) and antidepressants 130 (13%) prescribed for various psychiatric disorder. Usage of Sedative Hypnotics 104(10.4%), anti-psychotics 90(9%) and anticonvulsants 80 (8%) drugs in prescriptions. The incidence of polypharmacy (22%) was common occurrence in prescriptions. The commonest combination prescribed was of tricyclic antidepressant with benzodiazepines. Central anti-cholinergic was commonly prescribed with anti psychotics.Conclusions: Anti-anxiety drug (benzodiazepines) was the most frequently prescribed class of psychotropic drugs in various psychiatry disorders. The prescribing prevalence of Alprazolam with different brand names was more than that of other benzodiazepines. The combination of different psychotropic drugs were also prescribed

    The objective of our study was to describe oral and genital human papillomavirus (HPV) infection prevalence and concordance by sexual orientation among US men using a nationally representative sample. We conducted a retrospective cross-sectional analysis of the 2013-2016 National Health and Nutrition Examination Survey. The survey conducts a physical examination and collects oral rinse and genital swab specimens; demographic and health behaviors are self-reported. We used descriptive statistics and multivariate regression models to estimate HPV infection prevalence and the likelihood of HPV infection, respectively. All analyses were adjusted for National Health and Nutrition Examination Survey design and weights, and statistical significance was tested at a 2-sided P value of less than .05. Men who have sex with men had a statistically significantly higher prevalence of oral HPV (high-risk, 9-valent, 4-valent, and HPV 16 and 18), genital HPV (9-valent, 4-valent, and HPV 16 and 18), and concordant oral and genital HPV (high-risk and 9-valent) infections compared with heterosexual men. Improved HPV prevention among men is needed

    Reimbursement For Hpv Vaccine Cost in the Private Sector: a Comparison across Specialties

    Get PDF
    The human papillomavirus (HPV) vaccine is the most expensive of all routinely recommended pediatric vaccines. Adequate cost reimbursement by 3rd-party payers is a critical enabling factor for clinicians to continue offering vaccines. This study found that net returns from HPV vaccine cost reimbursements are lowest for family physicians (0.34/dose)andhighestforpediatricians(0.34/dose) and highest for pediatricians (5.08/dose). Furthermore, a $1 increment in return was associated with an increase in HPV vaccine doses administered (highest for family physicians; 0.08% per dollar). Reimbursement for HPV vaccine costs by private payers is adequate; however, return margins are small for non-pediatric specialties

    Parental intent to initiate and Complete the Human Papillomavirus Vaccine Series in the Usa: a Nationwide, Cross-Sectional Survey

    Get PDF
    BACKGROUND: Human papillomavirus (HPV) vaccine uptake among US adolescents is primarily dependent on the intent of their parents. to the best of our knowledge, an analysis quantifying parental intent to initiate and complete the HPV vaccine series in the USA at both the national and state level has not been done. We aim to estimate parental intent to initiate and complete the HPV vaccine series at the national-level and state-level and to identify reasons for lack of intent to initiate and complete the vaccine series. METHODS: This cross-sectional study uses data from the adolescent component of the 2017-18 National Immunization Survey (NIS-Teen). Study participants were parents or caregivers of US adolescents aged 13-17 years, who were most knowledgeable about the immunisation status of the adolescents. The primary outcome was parental intent to vaccinate the adolescent in the next 12 months. The secondary outcomes were (1) the prevalence of reasons given for lack of intent to initiate and complete the HPV vaccine series, and (2) the relationship between receiving a recommendation from a health-care provider to vaccinate and intent to initiate the vaccination series. We computed national-level and state-level estimates for parental lack of intent to initiate and to complete the vaccine series; population-level estimates were derived using survey weights. A survey design-adjusted Wald F test was used for bivariate analysis. A multivariate logistic regression model was used to examine the association between health-care provider recommendation and parental intent to initiate the series. Analyses were stratified by history of health-care provider recommendation to initiate the HPV vaccine series. FINDINGS: In 2017-18, the parent or caregiver of 82 297 US adolescents aged 13-17 years completed the NIS-Teen survey. 30 558 (37·1%) were unvaccinated and 9073 (10·8%) received only one HPV vaccine dose. Parents of 58·0% (17 171/29 086) of unvaccinated adolescents with data available on parental intent had no intention to initiate the HPV vaccine series. More than 65% of parents of unvaccinated adolescents in Idaho, Kansas, Michigan, Montana, Nebraska, North Dakota, Oklahoma, and Utah had no intention to initiate the HPV vaccine series. Parents of 23·5% (2166/9072) of initiators with data available on parental intent had no intention to complete the HPV vaccine series. More than 30% of parents in Arkansas, Florida, Georgia, Hawaii, Idaho, Utah, and West Virginia did not intend to complete the HPV vaccine series, whereas in the District of Columbia (11·2% [22/166]) and Rhode Island (20·4% [21/112]) parental lack of intent was relatively low (both regions have an HPV vaccine mandate). The most common reason for lack of intent among parents to initiate the vaccine for unvaccinated adolescents was safety concerns (22·8% [4182/16 455]); lack of a recommendation from a health-care provider (22·2% [440/1944]) was the most frequently cited reason for absence of intent to complete the series among parents of adolescents who received only one HPV vaccine dose. Receipt of a recommendation from a health-care provider was associated with greater odds of parental intent to initiate the HPV vaccine series (odds ratio 1·11, 95% CI 1·01-1·22). 45·5% (13 156/29 086) of parents of unvaccinated adolescents had reportedly received an HPV vaccine recommendation. Parents of 60·6% (7938/13 156) of unvaccinated adolescents with a recommendation from a health-care provider and data available on parental intent had no intention to initiate the series. INTERPRETATION: Lack of parental intent to initiate and complete the HPV vaccine series for adolescents is a major public health concern in the USA. Combating vaccine safety concerns and strong recommendations from health-care providers could improve the currently suboptimal HPV vaccination coverage. FUNDING: US National Cancer Institute

    Systematic investigation of channel coupling effects on elastic, inelastic and neutron transfer channels in 6^6Li+159^{159}Tb

    Elastic scattering angular distribution for weakly bound nucleus 6^{6}Li on the deformed rare earth 159^{159}Tb target nucleus has been measured at energies around the Coulomb barrier. The elastic scattering cross sections for this reaction consist of inelastic contributions from low lying excited states of 159^{159}Tb. The pure elastic cross-sections have been extracted from the admixture of elastic and inelastic data. The optical model potential parameters for the system have been obtained from the extracted pure elastic scattering cross sections. Coupled channel calculations have been performed with this set of potential parameters, to compare the theoretical and experimental inelastic scattering cross sections. The work has been extended to obtain the spectroscopic factor for 158^{158}Tb+n configuration from the experimental 1n-pickup data

    PURPOSE: Squamous cell carcinoma of the anus (SCCA) incidence and mortality rates are rising in the United States. Understanding state-level incidence and mortality patterns and associations with smoking and AIDS prevalence (key risk factors) could help unravel disparities and provide etiologic clues. METHODS: Using the US Cancer Statistics and the National Center for Health Statistics data sets, we estimated state-level SCCA incidence and mortality rates. Rate ratios (RRs) were calculated to compare incidence and mortality in 2014-2018 versus 2001-2005. The correlations between SCCA incidence with current smoking (from the Behavioral Risk Factor Surveillance System) and AIDS (from the HIV Surveillance system) prevalence were evaluated using Spearman\u27s rank correlation coefficient. RESULTS: Nationally, SCCA incidence and mortality rates (per 100,000) increased among men (incidence, 2.29-3.36, mortality, 0.46-0.74) and women (incidence, 3.88-6.30, mortality, 0.65-1.02) age ≥ 50 years, but decreased among men age \u3c 50 years and were stable among similar-aged women. In state-level analysis, a marked increase in incidence (≥ 1.5-fold for men and ≥ two-fold for women) and mortality (≥ two-fold) for persons age ≥ 50 years was largely concentrated in the Midwestern and Southeastern states. State-level SCCA incidence rates in recent years (2014-2018) among men were correlated ( CONCLUSION: During 2001-2005 to 2014-2018, SCCA incidence and mortality nearly doubled among men and women age ≥ 50 years living in Midwest and Southeast. State variation in AIDS and smoking patterns may explain variation in SCCA incidence. Improved and targeted prevention is needed to combat the rise in SCCA incidence and mitigate magnifying geographic disparities

    Initial Visible and Mid-IR Characterization of P/2019 LD₂ (ATLAS), an Active Transitioning Centaur Among the Trojans, with Hubble, Spitzer, ZTF, Keck, APO and GROWTH Imaging and Spectroscopy

    We present visible and mid-infrared imagery and photometry of Jovian co-orbital comet P/2019 LD₂ (ATLAS) taken with Hubble Space Telescope/WFC3 on 2020 April 1, Spitzer Space Telescope/IRAC on 2020 January 25, Zwicky Transient Facility between 2019 April 9 and 2019 Nov 8 and the GROWTH telescope network from 2020 May to July, as well as visible spectroscopy from Keck/LRIS on 2020 August 19. Our observations indicate that LD₂ has a nucleus with radius 0.2-1.8 km assuming a 0.08 albedo and that the coma is dominated by ∼100 μ m-scale dust ejected at ∼1 m/s speeds with a ∼1" jet pointing in the SW direction. LD₂ experienced a total dust mass loss of ∼10⁸ kg and dust mass loss rate of ∼6 kg/s with Afρ/cross-section varying between ∼85 cm/125 km² and ∼200 cm/310 km² between 2019 April 9 and 2019 Nov 8. If the Afρ/cross-section increase remained constant, it implies that LD₂ has remained active since ∼2018 November when it came within 4.8 au of the Sun, a typical distance for comets to begin sublimation of H₂O. From our 4.5 μm Spitzer observations, we set a limit on CO/CO₂ gas production of ∼10²⁷/∼10²⁶ mol/s. Multiple bandpass photometry of LD₂ taken by the GROWTH network measured in a 10,000 km aperture provide color measurements of g-r = 0.59±0.03, r-i = 0.18±0.05, and i-z = 0.01±0.07, colors typical of comets. We set a spectroscopic upper limit to the production of H₂O gas of ∼80 kg/s. Improving the orbital solution for LD₂ with our observations, we determine that the long-term orbit of LD₂ is that of a typical Jupiter Family Comet having close encounters with Jupiter coming within ∼0.5 Hill radius in the last ∼3 y to within 0.8 Hill radius in ∼9 y and has a 95% chance of being ejected from the Solar System in < 10 Myr
