Abstract
BACKGROUND: Increasing evidence suggests that post-TB lung disease (PTLD) causes significant morbidity and mortality. The aim of these clinical standards is to provide guidance on the assessment and management of PTLD and the implementation of pulmonary rehabilitation (PR).METHODS: A panel of global experts in the field of TB care and PR was identified; 62 participated in a Delphi process. A 5-point Likert scale was used to score the initial ideas for standards and after several rounds of revision the document was approved (with 100% agreement).RESULTS: Five clinical standards were defined: Standard 1, to assess patients at the end of TB treatment for PTLD (with adaptation for children and specific settings/situations); Standard 2, to identify patients with PTLD for PR; Standard 3, tailoring the PR programme to patient needs and the local setting; Standard 4, to evaluate the effectiveness of PR; and Standard 5, to conduct education and counselling. Standard 6 addresses public health aspects of PTLD and outcomes due to PR.CONCLUSION: This is the first consensus-based set of Clinical Standards for PTLD. Our aim is to improve patient care and quality of life by guiding clinicians, programme managers and public health officers in planning and implementing adequate measures to assess and manage PTLD.

Abstract
Alkaline earth Rydberg atoms are very promising tools for quantum technologies. Their highly excited outer electron provides them with the remarkable properties of Rydberg atoms and, notably, with a huge coupling to external fields or to other Rydberg atoms while the ionic core retains an optically active electron. However, low angular-momentum Rydberg states suffer almost immediate autoionization when the core is excited. Here, we demonstrate that strontium circular Rydberg atoms with a core excited in a 4D metastable level are impervious to autoionization over more than a few millisecond time scale. This makes it possible to trap and laser-cool Rydberg atoms. Moreover, we observe singlet to triplet transitions due to the core optical manipulations, opening the way to a microwave to optical quantum interface.

Abstract
The aim of this prospective study was to report on the response to treatment of central giant cell lesions (CGCL) with intralesional corticosteroid injections. Consecutive cases of CGCL were treated with a biweekly intralesional injection of 20mg/ml triamcinolone hexacetonide diluted in an anaesthetic solution of 2% lidocaine/epinephrine 1:200 000 at the proportion 1:1. All patients were monitored using cone beam computed tomography. Eleven patients were treated; their ages ranged from 15-34 (mean 22 years); and eight lesions were in the mandible, and three in the maxilla. Three cases were diagnosed as non-aggressive, and eight as aggressive. Six cases presented good results (four aggressive and two non-aggressive); three cases presented a moderate response (two aggressive and one non-aggressive); and two had a poor response to treatment (both aggressive). In four cases with a good response, osteoplasty was done. In all cases with a moderate response, the remaining lesion was curetted. Cases with a poor response were submitted to either curettage or denosumab injections. Corticotherapy, as main or neoadjuvant therapy, may be an option for treatment of CGCL.

Abstract
Rare-earth orthochromites with distorted perovskite structure (e.g. RCrO3, R = Sm, Gd) have been under strong debate with respect to the origin of their ferroelectric order. Of particular interest is the question of whether such orthochromites are, in fact, magnetically driven improper ferroelectrics, as many rare-earth manganites or orthoferrites. Here we show, by studying at the atomic scale the rare-earth SmCrO3 system that a distortion of the Sm local environment emerges within the paramagnetic phase, near room temperature. Our Electric Field Gradient measurements combined with first-principles calculations show that the emergent phase cannot be simply ascribed to the Pna21 structure as reported for GdCrO3 or SmCrO3. Instead a local inhomogeneous state, where regular non-polar and polar distorted environments coexist, develops at low temperatures.

Abstract
This study aimed to describe the association of Borrelia burgdorferi
s.s. with ixodid tick cell lines by flow cytometry and fluorescence and confocal
microscopy. Spirochetes were stained with a fluorescent membrane marker (PKH67 or
PKH26), inoculated into 8 different tick cell lines and incubated at 30°C for 24 h.
PKH efficiently stained B. burgdorferi without affecting bacterial
viability or motility. Among the tick cell lines tested, the Rhipicephalus
appendiculatus cell line RA243 achieved the highest percentage of
association/internalization, with both high (90%) and low (10%) concentrations of
BSK-H medium in tick cell culture medium. Treatment with cytochalasin D dramatically
reduced the average percentage of cells with internalized spirochetes, which passed
through a dramatic morphological change during their internalization by the host cell
as observed in time-lapse photography. Almost all of the fluorescent bacteria were
seen to be inside the tick cells. PKH labeling of borreliae proved to be a reliable
and valuable tool to analyze the association of spirochetes with host cells by flow
cytometry, confocal and fluorescence microscopy.

Abstract
UNLABELLED Isolation of local strains is mandatory for the success of control programs. However, clinical samples are typically contaminated by other bacteria, which impair leptospires growth. The purpose of this study was to evaluate the use of a previously reported EMJH-STAFF media in the recovery of pathogenic leptospires from bovine clinical samples, namely urine (n = 123) and vaginal fluid-VF (n = 102). EMJH-STAFF presented less contamination than EMJH (<0·005), which was more evident in VF culture tubes. Nine pure leptospires cultures were obtained, six from urine (4·9%) and three from VF (2·9%). From those, seven grew on EMJH-STAFF, one on EMJH and one in both media. All the isolates were confirmed as pathogenic leptospires by lipL32-PCR, and sequencing of partial rrs showed them to belong to Leptospira noguchii, Leptospira santarosai and Leptospira interrogans species. EMJH-STAFF media was an important tool in the recovery of leptospires from bovine clinical samples. SIGNIFICANCE AND IMPACT OF THE STUDY The slow growth of leptospires and overgrowth of co-existing micro-organisms from environmental and microbiota are the major difficult to recovery Leptospira from animal clinical samples. Implementing an efficient control programme is essential to determine circulating leptospires in the region and their reservoirs. This study evaluated the relationship of a selective media (EMJH-STAFF) on the recovery of pathogenic leptospires (Leptospira noguchii, Leptospira santarosai and Leptospira interrogans), from bovine clinical samples (urine and vaginal fluid). EMJH-STAFF seems to be an important tool in obtaining local strains for epidemiological and control purposes.

Abstract
Central giant-cell granulomas are benign, but occasionally aggressive, lesions that traditionally have been treated surgically. 21 cases of central giant-cell granuloma of the jaw were treated with intralesional injection of corticosteroids. The treatment protocol adopted was intralesional injection of 20mg/ml triamcinolone hexacetonide diluted in an anaesthetic solution of 2% lidocaine/epinephrine 1:200,000 in the proportion 1:1; 1.0ml of the solution was infiltrated for every 1cm(3) of radiolucid area of the lesion, totalling 6 biweekly applications. Ten patients had aggressive lesions and 11 nonaggressive. Two patients showed a negative response to the treatment and underwent surgical resection, 4 showed a moderate response and 15 a good response. 8 of the 19 who had a moderate-to-good response to the drug treatment underwent osteoplasty to reestablish facial aesthetics. In these cases, only mature or dysplastic bone was observed, with the presence or absence of rare giant multinucleated cells. The advantages of this therapy are its less-invasive nature, the probable lower cost to the patient, lower risk and the ability to treat the lesion surgically in the future, if necessary.

Abstract
OBJECTIVES Recent findings have suggested that ductus venosus blood flow may be influenced by fetal gender. The aim of this study was to investigate further the influence of fetal gender on ductus venosus Doppler flow in the first trimester. METHODS This was a cross-sectional and retrospective study performed between January 1998 and January 2003. A total of 932 fetuses at between 10 and 14 weeks' gestation were included. The following inclusion criteria were used: singleton gestation; crown-rump length between 39 and 84 mm; and absence of fetal anomalies. The following variables of the ductus venosus were evaluated: peak velocity during ventricular systole (S-wave) and diastole (D-wave); nadir during atrial contraction in late diastole (A-wave); pulsatility index for veins (PIV); peak velocity index for veins (PVIV); and time-averaged maximum velocity (TAMXV). RESULTS Four hundred and forty-eight (48.1%) female and 484 (51.9%) male fetuses were included in the study. Comparing males and females at between 10 and 14 weeks' gestation, there was no statistically significant difference in S-wave, D-wave, A-wave, PIV, PVIV or TAMXV. CONCLUSIONS Our study suggests that fetal gender does not influence ductus venosus blood flow in the first trimester.

Abstract
OBJECTIVES To establish reference curves for ductus venosus blood flow velocities during the first trimester and compare them with previously published curves. METHODS This was a cross-sectional and retrospective study performed between January 1998 and January 2003. The following inclusion criteria were used: singleton pregnancy, velocity measurements taken when the crown-rump length (CRL) was between 34 and 84 mm, absence of fetal anomalies, full-term pregnancy and newborn birth weight appropriate for gestational age. The following variables of the ductus venosus were measured: peak velocity during ventricular systole (S-wave) and diastole (D-wave), nadir during atrial contraction in late diastole (A-wave), time-averaged maximum velocity (TAMXV) and pulsatility index for veins (PIV). RESULTS A total of 843 fetuses were included. The mean CRL was 62 (range, 34-84) mm. The S-wave, D-wave, TAMXV and PIV were normally distributed, and logarithmic transformation was performed to achieve a normal distribution for the A-wave. S-wave, D-wave and A-wave and TAMXV increased with CRL. PIV increased up to a CRL of 63 mm and decreased thereafter. Regression analysis revealed a significant quadratic relationship between PIV and CRL. CONCLUSIONS S-wave, D-wave, A-wave velocities and TAMXV in the ductus venosus increase with CRL between 34 and 84 mm. The reference range for PIV has a biphasic pattern, with an initial non-significant increase up to a CRL of 63 mm and a fall thereafter.

Abstract
The aetiology of Proteus syndrome (PS) is yet unclear. This disease includes partial gigantism of the hands and/or feet, nevi, hemihypertrophy due to overgrowth of long bones, subcutaneous tumours, macrocephaly, cranial hyperostosis, and pulmonary and renal abnormalities. This case report is about a 17-year-old boy with two uncommon findings associated with PS: apnoea-hypopnoea and mandibular retrusion. A multidisciplinary team was important to provide professional care for this patient. Dentists and physicians proposed an adjusted treatment plan. Maxillary disjunction was achieved with a combination of orthodontic treatment and surgical procedure. This represented the initial care for malocclusion treatment and also the preparation for orthognathic surgery. The oral maxillofacial surgeon and the otorhinolaryngologist proposed this approach in an attempt to improve pharynx airflow. The patient has been followed for almost 3 years.

Abstract
The elevated T-maze is an animal model of anxiety, consisting of three elevated arms: one enclosed and two open. Inhibitory avoidance of the open arms-representing learned fear-has been related to generalized anxiety and the unconditioned escape from one of the open arms to panic. In the present study, we investigated the effects of acute and chronic (21 days) administration of imipramine (5, 10, and 15 mg/kg; IP) in male Wistar rats that have been previously exposed for 30 min to one of the open arms of the T-maze, 24 h before the test. The results show that this preexposure shortens the first escape latency, without changing open-arm avoidance. Under these experimental conditions, chronic imipramine exerted anxiolytic-like effects in the two elevated T-maze tasks; impaired the acquisition of inhibitory avoidance and prolonged escape latency from the open arms. Acute imipramine enhanced both avoidance and escape latencies. Both acute and chronic imipramine decreased locomotor activity measured in a square arena. The obtained results are compatible with the view that inhibitory avoidance and one-way escape in the elevated T-maze reflect different types of fear/anxiety, that may be related to generalized anxiety and panic disorder, respectively.

Abstract
The efficiency and the viability of three hemoglobin screening programs were investigated. They were offered on a voluntary basis to a Brazilian population and started with the analysis of blood donors, pregnant women and students. The hemoglobin screening was done through optional exams which included electrophoresis of hemoglobin and complementary hematological tests. A total of 13,670 people were tested over a period of 39 months and a total of 644 individuals with hereditary hemoglobin disorders were detected - 4. 7% of the samples examined. The programs showed satisfactory indicators of viability and efficiency, expressed by the significative proportion of exams performed among the probands and their relatives.
