RESUMO

We report the final measurement of the neutrino oscillation parameters Δm_{32}^{2} and sin^{2}θ_{23} using all data from the MINOS and MINOS+ experiments. These data were collected using a total exposure of 23.76×10^{20} protons on target producing ν_{µ} and ν[over ¯]_{µ} beams and 60.75 kt yr exposure to atmospheric neutrinos. The measurement of the disappearance of ν_{µ} and the appearance of ν_{e} events between the Near and Far detectors yields |Δm_{32}^{2}|=2.40_{-0.09}^{+0.08}(2.45_{-0.08}^{+0.07})×10^{-3} eV^{2} and sin^{2}θ_{23}=0.43_{-0.04}^{+0.20}(0.42_{-0.03}^{+0.07}) at 68% C.L. for normal (inverted) hierarchy.

RESUMO

AIMS: To evaluate the impact of addition of rapid tests for tuberculosis (TB) to mass screening and passive case finding on the burden of TB in high-incidence prisons of Azerbaijan. MATERIALS AND METHODS: All new and relapse TB cases notified in 01.01.2009-31.12.2015 were retrospectively included. RESULTS: 2,315 TB patients were identified in 19 prisons. Implementation of the rapid tests to the case finding algorithms lead to 3-, 10- and 5-fold decrease in the annual rates of the notified, smear-positive and RIF-resistant TB cases, respectively. After introduction of rapid tests into the screening algorithms, there were significant linear trends towards decrease in the notified (p=0.009), smear-positive (p=0.011) and RIF-resistant TB cases (p=0.02) with the annual rates of decrease (95% confidence interval (CI)) being -435 (-614; -255), -356 (-517; -195), and -99 (-160; -38), respectively. Utilization of rapid tests also significantly increased treatment success with first-line drugs among all cases, cases detected by mass screening and those, detected by passive case finding [adjusted odds ratio (aOR)=2.38, 95% CI:1.86-3.05, aOR=4.56, 95% CI:2.64-7.89 and aOR=2.60, 95% CI:1.81-3.75, respectively]. CONCLUSIONS: Introduction of rapid tests into the screening lead to decline in the burden of TB and RIF-resistance, and improved outcomes of treatment with first-line drugs in prisons.

RESUMO

Objetivos: Evaluar el impacto de los tests rápidos para tuberculosis (TB) añadidos a los sistemas de cribado y de búsqueda pasiva de casos en la carga de enfermedad de TB en centros penitenciarios con alta incidencia de la misma en Azerbaiyán. Material y métodos: Inclusión retrospectiva de todos los casos nuevos y recurrentes de TB notificados desde el 1 de enero de 2009 hasta el 31 de diciembre de 2015. Resultados: Se identificaron un total de 2315 pacientes en 19 centros penitenciarios diferentes. Se implementaron los tests rápidos a los algoritmos de identificación de casos con la consiguiente reducción en las tasas anuales de los casos de TB notificados, los casos de baciloscopia positiva y los de TB resistente a la rifampicina (a una tercera, décima y quinta parte respectivamente). Tras la introducción de los tests rápidos en los algoritmos de cribado se observó una tendencia lineal significativa a la reducción de los casos notificados (p=0,009), los casos de baciloscopia positiva (p=0,011) y los de TB resistente a la rifampicina (p=0,02) con tasas anuales de reducción (con intervalo de confianza al 95%) de -432 (-614;-255), -356 (-517; -195) y -99 (-160;-38) respectivamente. La utilización de los tests rápidos también se tradujo en un incremento significativo del éxito terapéutico con fármacos de primera línea en todos los casos: los detectados por cribado y los identificados por búsqueda pasiva [odds ratio ajustado (Ora)= 2.38, IC95% 1,86-3,05; ORa=4,56, IC 95%:2,64-7,89 y ORa=2,60, IC 95% :1,81-3,75, respectivamente]. Conclusiones: La introducción de los tests rápidos en los sistemas de cribado de TB conllevan reducciones en la carga de enfermedad y en la resistencia a rifampicina con mejores resultados terapéuticos con fármacos de primera línea en centros penitenciarios

RESUMO

OBJECTIVE: To determine the factors predictive of cure among inmates with pulmonary rifampicin-resistant tuberculosis (R(R)-TB). DESIGN: A total of 444 new and previously treated patients with pulmonary R(R)-TB who started treatment with second-line anti-tuberculosis drugs in the penitentiary system of Azerbaijan during the period 1 April 2007-28 February 2013 were retrospectively subjected to multivariate logistic regression analysis. RESULTS: Of the 444 patients, 78.4% were cured. A higher number of effective bactericidal drugs in the regimen at months 7-12 and 13-18, normal chest X-ray and body mass index ⩾18.5 kg/m(2) at the treatment start significantly increased the chances of cure both in all cases (aOR 2.29, aOR 4.39, aOR 1.18, aOR 1.98 and aOR 1.97, respectively) and in retreatment cases (aOR 3.88, aOR 5.02, aOR 1.17, aOR 2.26 and aOR 1.90, respectively). There was no added benefit of using moxifloxacin (MFX) as compared to levofloxacin (LVX) in case of resistance to ofloxacin. CONCLUSION: The use of a higher number of effective bactericidal drugs after month 6 of treatment for R(R)-TB was found to be the main factor associated with cure. No added benefit of using MFX instead of LVX was found. High cure rates can be achieved among vulnerable population groups such as prisoners if comprehensive TB control measures are in place to ensure low loss to follow-up.

RESUMO

We report on the first cross section measurements for charged current coherent pion production by neutrinos and antineutrinos on argon. These measurements are performed using the ArgoNeuT detector exposed to the NuMI beam at Fermilab. The cross sections are measured to be 2.6(-1.0)(+1.2)(stat)(-0.4)(+0.3)(syst)×10(-38) cm(2)/Ar for neutrinos at a mean energy of 9.6 GeV and 5.5(-2.1)(+2.6)(stat)(-0.7)(+0.6)(syst)×10(-39) cm(2)/Ar for antineutrinos at a mean energy of 3.6 GeV.

RESUMO

The ArgoNeuT Collaboration presents the first measurements of inclusive muon neutrino charged current differential cross sections on argon. Obtained in the NuMI neutrino beam line at Fermilab, the flux-integrated results are reported in terms of outgoing muon angle and momentum. The data are consistent with the Monte Carlo expectation across the full range of kinematics sampled, 0°<θ(µ)<36° and 0
