Abstract
Transition metal dichalcogenides (TMDs) are interesting for understanding the fundamental physics of two-dimensional (2D) materials as well as for applications to many emerging technologies, including spin electronics. Here, we report the discovery of long-range magnetic order below T M = 40 and 100 K in bulk semiconducting TMDs 2H-MoTe2 and 2H-MoSe2, respectively, by means of muon spin rotation (μSR), scanning tunneling microscopy (STM), and density functional theory (DFT) calculations. The μSR measurements show the presence of large and homogeneous internal magnetic fields at low temperatures in both compounds indicative of long-range magnetic order. DFT calculations show that this magnetism is promoted by the presence of defects in the crystal. The STM measurements show that the vast majority of defects in these materials are metal vacancies and chalcogen-metal antisites, which are randomly distributed in the lattice at the subpercent level. DFT indicates that the antisite defects are magnetic with a magnetic moment in the range of 0.9 to 2.8 μB. Further, we find that the magnetic order stabilized in 2H-MoTe2 and 2H-MoSe2 is highly sensitive to hydrostatic pressure. These observations establish 2H-MoTe2 and 2H-MoSe2 as a new class of magnetic semiconductors and open a path to studying the interplay of 2D physics and magnetism in these interesting semiconductors.

Abstract
The Consolidated Standards of Reporting Trials for Patient-Reported Outcomes (CONSORT PRO) and the Consensus on Exercise Reporting Template (CERT) have been developed to improve the quality and transparency of reporting standards in scientific research. The purpose of this study was to provide evidence for the adoption of CONSORT PRO and CERT by researchers examining the link between exercise and quality of life in individuals living with osteoporosis. A systematic search was conducted to identify randomized control trials published in English evaluating exercise interventions on quality of life in individuals living with osteoporosis. Reporting standards were assessed using CONSORT PRO and CERT. A total of 127 studies were identified with 23 meeting inclusion criteria. "Good" evidence for eight (42.1%) CONSORT PRO and two (12.5%) CERT items was found. Adherence to CONSORT PRO was not related to the year of publication, journal impact factor, or study quality. Adherence to CONSORT PRO and CERT reporting standards is inadequate in the literature examining exercise interventions on quality of life in individuals living with osteoporosis. Sufficient reporting is paramount to knowledge translation, interpretation by interventionists, and clinician confidence in understanding if (and how) exercise is associated with quality of life outcomes in this cohort. Concerns associated with failure to include this information are highlighted.

Abstract
INTRODUCTION Early diagnosis is necessary for the success of the tuberculosis (TB) program. GOAL To identify factors associated with diagnosis delay of TB in Huambo, Angola. MATERIAL AND METHODS Cross-sectional study carried out in patients diagnosed with TB at the Huambo Anti-Tuberculosis Dispensary (ATD) in the period between October 2015 and January 2016. RESULTS The 247 patients included in the analysis had a median age of 27 years and a median diagnosis delay of 64 days. In the univariate analysis, age, consumption of alcoholic beverages, living in a residence further than 10km from a healthcare unit, and looking for any other health unit than the emergency unit were associated with longer diagnosis delay. In the multivariate analysis model, to be between 30 and 44 years of age (p=0.018), to live in a residence more than 10km from a healthcare unit (p=0.006) and to turn to traditional medicine as the first healthcare option (p<0.001) were factors that led to greater time delay before diagnosis. CONCLUSIONS In the Huambo province, age, distance to healthcare facility and the first healthcare service consulted were associated with diagnosis delay of TB.

Abstract
RESUMO As neoplasias ovarianas em gatas são raras e, quando relatadas, estão associadas a animais senis, assim como a piometra de causa não iatrogênica. O objetivo deste trabalho foi relatar o caso de uma gata jovem com neoplasia ovariana, tumor de células da granulosa associado ao complexo hiperplasia endometrial cística/piometra (HECP). O animal foi atendido no setor de Reprodução Animal e Obstetrícia Veterinária (RAOV) de um Hospital Veterinário Escola, com histórico de monta natural recente, anorexia, êmese, polidipsia, poliúria e descarga vaginal purulenta. Ao exame físico, observou-se apatia, mucosas ictéricas, aumento de volume da região abdominal e presença de secreção vaginal purulenta. À ultrassonografia, foi visibilizado conteúdo ecogênico no útero diagnóstico de HECP e estrutura ecogênica na cavidade abdominal, na região ovariana, confirmado pelo exame histopatológico como sendo tumor das células da granulosa. A conduta terapêutica adotada foi a cirurgia de ovariossalpingo-histerectomia (OSH).

Abstract
OVERVIEW In Uruguay, colonies of honey bees moving to Eucalyptus grandis plantation in autumn habitually become infected with the microsporidian Nosema ceranae , a parasite that attacks the digestive system of bees. Beekeepers attributed to N. ceranae depopulation of the colonies that often occurs at the end of the blooming period, and many use the antibiotic fumagillin to reduce the level of infection. The aim of this study was to compare the effectiveness of four different fumagillin treatments and determine how this antibiotic affects the strength of the colonies during the winter season. The colonies treated with fumagillin in July showed less spore load at the end of applications, being the most effective the following treatments: the four applications sprayed over bees of 30 mg of fumagillin in 100 ml of sugar syrup 1:1, and four applications of 90 mg of fumagillin in 250 ml of sugar syrup 1:1 using a feeder. However, 2 month after the treatment applications, the colonies treated with fumagillin were the same size as the untreated colonies. In September, the colonies treated and not treated with fumagillin did not differ in colony strength (adult bee population and brood area) or spores abundance. Our study demonstrates that fumagillin treatment temporarily decreased the spore load of N. ceranae , but this was not reflected in either the size of the colonies or the probability of surviving the winter regardless of the dose or the administration strategy applied. Given the results obtained, we suggest to not perform the pharmacological treatment under the conditions described in the experiment. RESUMEN En Uruguay las colonias de abejas melíferas que se trasladan a las forestaciones de Eucalyptus grandis en otoño indefectiblemente se infectan con el microsporido Nosema ceranae , parásito que ataca el sistema digestivo de las abejas. Los apicultores atribuyen a N. ceranae el despoblamiento de las colonias que ocurre con frecuencia al terminar el periodo de floración y muchos emplean el antibiótico fumagilina para reducir el nivel de infección. El objetivo de este estudio fue comparar la eficacia de cuatro tratamientos diferentes con fumagilina y determinar cómo incide en la fortaleza de las colonias durante la invernada. Las colonias tratadas con fumagilina en julio presentaron una menor carga de esporas al terminar las aplicaciones, siendo los tratamientos más eficaces el de 4 aplicaciones mediante asperjado sobre las abejas de 30 mg de fumagilina en 100 ml de jarabe de azúcar 1:1, y el de 4 aplicaciones de 90 mg de fumagilina en 250 ml de jarabe de azúcar 1:1 utilizando un alimentador. Sin embargo, durante el período de experimentación, las colonias tratadas con antibiótico presentaron igual tamaño que las colonias no tratadas. En setiembre, las colonias tratadas y no tratadas con fumagilina no se diferenciaron en la intensidad de infección ni en su tamaño. En las condiciones en que se realizó el estudio, la aplicación de fumagilina disminuyó temporalmente la carga de esporas de N. ceranae pero esto no se reflejó en el tamaño de las colonias ni en la probabilidad de sobrevivir el invierno.

Abstract
Ultrahigh energy cosmic ray air showers probe particle physics at energies beyond the reach of accelerators. Here we introduce a new method to test hadronic interaction models without relying on the absolute energy calibration, and apply it to events with primary energy 6-16 EeV (E_{CM}=110-170 TeV), whose longitudinal development and lateral distribution were simultaneously measured by the Pierre Auger Observatory. The average hadronic shower is 1.33±0.16 (1.61±0.21) times larger than predicted using the leading LHC-tuned models EPOS-LHC (QGSJetII-04), with a corresponding excess of muons.
