Abstract
SETTING Five urban TB diagnostic centres in Lusaka, Zambia. OBJECTIVE To determine the proportion of bacteriologically confirmed pre-treatment lost to follow-up (LTFU) patients with TB found at the study settings in 2020. DESIGN This was a retrospective cohort study in which the TB laboratory and treatment registers at the study sites were cross-matched. RESULTS A total of 1,085 bacteriologically confirmed patients with TB were found in the laboratory TB registers at the study settings. Of these, 809 (74.6%) were males, whereas 8 (0.7%) were children, 1,005 (92.6%) were diagnosed using Xpert, 78 (7.2%) by microscopy. A total of 91 (8.4%, 95% CI 6.8-10.2) were determined to be pre-treatment LTFU. Those who had very low (14.0%, 95% CI 8.5-21.2) and low (11.8%, 95% CI 8.4-16.0) results on Xpert were respectively 3.1 (95% CI 1.6-6.0) and 2.6 (95% CI 1.4-4.8) times more likely to become pre-treatment LTFU than those who had medium (4.5%, 95% CI 2.5-7.4) results. The proportions of pre-treatment LTFU varied among the study sites from 0.7% to 16.1%. CONCLUSION Health facilities should strive to account for every patient with TB, with particular attention to those who are bacteriologically confirmed.

Abstract
Food cues during fasting elicit Pavlovian conditioning to adapt for anticipated food intake. However, whether the olfactory system is involved in metabolic adaptations remains elusive. Here we show that food-odor perception promotes lipid metabolism in male mice. During fasting, food-odor stimulation is sufficient to increase serum free fatty acids via adipose tissue lipolysis in an olfactory-memory-dependent manner, which is mediated by the central melanocortin and sympathetic nervous systems. Additionally, stimulation with a food odor prior to refeeding leads to enhanced whole-body lipid utilization, which is associated with increased sensitivity of the central agouti-related peptide system, reduced sympathetic activity and peripheral tissue-specific metabolic alterations, such as an increase in gastrointestinal lipid absorption and hepatic cholesterol turnover. Finally, we show that intermittent fasting coupled with food-odor stimulation improves glycemic control and prevents insulin resistance in diet-induced obese mice. Thus, olfactory regulation is required for maintaining metabolic homeostasis in environments with either an energy deficit or energy surplus, which could be considered as part of dietary interventions against metabolic disorders.

Abstract
Abstract
Background
The current system of HeartFlow fractional flow reserve derived from computed tomography (FFRCT) is not available for stented coronary arteries. However, the latest version of HeartFlow FFRCT has the potential of rendering an accurate assessment for stented coronary arteries.
Objectives
To evaluate the feasibility of FFRCT for the stented coronary arteries.
Methods
We retrospectively enrolled patients with a history of coronary stent implantation who underwent invasive fractional flow reserve (FFR) for the stented coronary arteries within 3 months after coronary computed tomographic angiography (cCTA). As a subgroup analysis, we analyzed optical coherence tomography (OCT) images in patients who underwent OCT for stented vessels. OCT was performed as a part of the Kobe University Hospital OCT registry, which is a single-centre registry of consecutive patients who underwent OCT for the coronary arteries. The diagnostic performance of HeartFlow FFRCT for stented vessels was evaluated by comparing with that of cCTA alone. Minimum lumen area (MLA) within stent segments derived from cCTA was also compared with MLA derived from optical coherence tomography (OCT).
Results
A total of 30 vessels in 23 patients were studied. The diagnostic accuracy, sensitivity, specificity, positive and negative predictive value of FFRCT for myocardial ischemia using invasive FFR as a reference standard was 73.3%, 88.9%, 67.7%, 53.3% and 93.3%, respectively. FFRCT provided superior diagnostic performance than cCTA alone (p=0.016). FFRCT was significantly correlated with the invasive FFR (r=0.620, p<0.001), and Bland-Altman plot showed a mean bias of −0.041 with 95% limit of agreement of −0.173 to 0.092 (Figure 1). Among a total of 30 studied vessels, OCT was available for 25 vessels. MLA derived from cCTA correlated significantly with that derived from OCT (r=0.695, p<0.001), and Bland-Altman plot showed a mean bias of −0.32 mm2 with 95% limit of agreement of −2.89 to 2.25 mm2 (Figure 2).
Conclusions
The latest version of the HeartFlow FFRCT has the potential to be available for stented coronary arteries. Further investigation is required to elaborate our results.

Abstract
SETTING An urban TB diagnostic centre in Lusaka, Zambia. OBJECTIVE To re-evaluate treatment outcomes of all bacteriologically confirmed TB patients registered in 2018. DESIGN This was a retrospective cohort study on TB patients. Treatment outcomes of patients who were transferred out were retrieved. RESULTS A total of 182 patients were registered, 26 of whom had missing documents; these were excluded from the study. Of the remaining 156 patients who were reviewed, 86 (55.1%) were correctly evaluated by the centre, 35 (22.4%) were incorrectly evaluated and 35 (22.4%) were 'transferred out' (not evaluated). As a result of this review, the number of evaluated patients increased from 86 (55.1%) to 150 (96.2%). The cure and treatment success rates rose from 43.6% and 44.2%, respectively, to 57.7% and 73.1%, respectively. Of note, 14 of the 35 patients who were initially declared 'transferred out' did not actually reach their treatment facilities and ended up being lost to follow-up. CONCLUSION This study shows that it is possible to evaluate almost all TB patients. Re-evaluation of treatment outcomes of TB patients revealed the problems in the TB services that need to be improved in the future.

Abstract
Abstract
Background
It has been reported that balloon pulmonary angioplasty (BPA) could dramatically improve hemodynamics in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, some patients have shown poor response in oxygenation and lung function even after BPA. The aim of our study was to evaluate the efficacy of BPA using clinical indicators and to investigate lung function and residual hypoxemia.
Method
Consecutive 103 patients who underwent BPA from September 2011 to August 2018 were enrolled. We evaluated hemodynamics with right heart catheterization, respiratory function test, arterial blood gas examination, and exercise capacity with 6 minute-walk-distance (6MWD).
Result
At the median 12-month follow-up after the final BPA session, following examination findings were significantly improved. Mean pulmonary artery pressure (39.0±8.2mmHg, 23.2±8.4mmHg, p<0.001), Pulmonary vascular resistance (782±378 dynes / sec / cm-5, 331±187 dynes / sec / cm-5, p<0.001), 6 MWD (310±94 m, 363±119 m, p<0.001), PaO2 (63.1±15.8 mmHg, 68.5±13.6 mmHg, p=0.044),%VC (88.5±17.1, 91±16.3, p=0.036). However, the following examination findings did not improve after BPA. Oxygen desaturation during 6MWD test (−11.9±6.3, 12±7.9, p=0.65), %DLCO (64.2 17.1, 61.3 16.8, p=0.147).
Conclusion
BPA could dramatically improve hemodynamics and exercise tolerance. However, arterial oxygenation was not normalized after BPA. Moreover, oxygen desaturation in exercise, and %DLCO were almost unchanged. These observations might suggest the remaining arteriopathy in capillary level of pulmonary artery, but further research is needed.

Abstract
Abstract
Background
It has been previously reported that poor subpleural perfusion (PSP) in dual-energy computed tomography (DE-CT) might suggest the microvasculopathy in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, it remains unclear whether pathological findings of microvasculopathy in CTEPH and pulmonary arterial hypertension (PAH) are equivalent. The aim is to evaluate the microvasculopathy in CTEPH and PAH by using clinical parameters and DE-CT.
Methods
We retrospectively reviewed PSP (defined as subpleural spaces either not or minimally perfused in all segments) of consecutive treatment-naïve 89 CTEPH patients and 20 PAH patients who underwent DECT from Feb. 2015 to Dec. 2019.
We also evaluated hemodynamic parameters and DE-CT parameters including quantitative evaluation of pulmonary blood volume (PBV) which was calculated as the average of entire lung iodine density.
Results
PSP was observed in 49.4% of patients in CTEPH group versus 5.0% in PAH group (p<0.01).
There were no significant differences in hemodynamics and lung PBV between CTEPH group and PAH group (mean pulmonary arterial pressure; 36.4±10.4mmHg vs 38.3±8.5mmHg p=0.464, pulmonary vascular resistance; 700±388dyne*sec/cm5 vs 805±440 dyne*sec/cm5 p=0.288, lung PBV; 24.9±6.4 Hounsfield Unit vs 22.0±6.6 Hounsfield Unit p=0.06, respectively), however diffusing capacity for carbon monoxide (%DLCO/VA) was significantly lower (69.5±16.8% vs 45.7±23.7% p<0.01) in PAH group.
Conclusion
PSP in DE-CT, which was observed more frequently in patients with CTEPH, might suggest the different mechanism of microvasculopathy from PAH in patients with CTEPH. Microvasculopathy in CTEPH would be diffuse very distal thrombosis. DE-CT is effective modality to detect microvasculopathy of diffuse distal thrombosis in patients with CTEPH.

Abstract
Abstract
Background
The existence of microvasculopathy in chronic thromboembolic pulmonary hypertension (CTEPH) had been suggested. However, the impact of microvasculopathy for pathophysiology had been unknown. Recently dual-energy computed tomography (DECT) can produce a sensitive iodine distribution map in lung fields to quantify lung perfusion, which may indicate the existence of microvasculopathy according to poor subpleural perfusion.
This study aimed to examine the therapeutic efficacy of interventional treatment (pulmonary endarterectomy or/and balloon pulmonary angioplasty) in CTEPH with microvasculopathy.
Methods
We retrospectively reviewed poor subpleural perfusion (defined as subpleural spaces either not or minimally perfused in all segments) and hemodynamics of 70 consecutive CTEPH patients who underwent DECT before and after interventional therapy from January 2014 to January 2020.
Patients were divided according to poor subpleural perfusion in DECT images before treatment: a microvasculopathy group (MV group, n=37) or a non-microvasculopathy group (Non-MV group, n=33).
We evaluated clinical parameters as WHO functional class (WHO-Fc), 6-min walk distance, respiratory function test, cardiopulmonary exercise test, hemodynamic parameters, and DECT parameters at baseline and after the treatments. DECT parameters as quantitative evaluation of pulmonary blood volume (PBV) calculated as the average of entire lung iodine density.
Results
After interventional treatments, WHO-Fc improved in 33 patients in MV group, and 27 patients in Non-MV group (p=0.50).
In MV group, baseline mean pulmonary arterial pressure (mPAP), pulmonary vascular resistance (PVR) and VE/VCO2 slope were higher (38.3±9.3 vs. 33.2±10.8 mmHg p=0.04, 818±394 vs. 539±289 dyne*sec/cm5 p<0.01 and 43.7±11.3 vs. 35.2±6.9 p<0.01, respectively) and PBV were lower (43.7±11.3 vs. 35.2±6.9 Hounsfield Unit p<0.01) After the treatments, mPAP, PVR, VE/VCO2 slope and PBV showed almost equivalent between the groups (19.5±4.1 vs. 20.6±5.1 mmHg p=0.35, 272±111 vs 251±109 dyne*sec/cm5 p=0.42, 29.2±6.3 vs. 26.0±6.1 p=0.06 and 27.1±6.6 vs. 29.6±6.6 Hounsfield Unit p=0.13).
Diffusing capacity for carbon monoxide (%DLCO/VA) did not improve after treatment in both groups (MV group: 59.5±13.1 to 58.8±11.9% p=0.43. Non-MV group: 77.8±13.4% to 70.5±10.8% P<0.01).
Conclusion
Hemodynamics, pulmonary perfusion, exercise capacities significantly improved after the treatments in spite of the existence or absence of microvasculopathy. However, DLCO which might indicate the existence of microvasculopathy did not improve. Interventional treatments could not improve microvasculopathy because of their limit of accessibilities.

Abstract
Abstract
Background
The management of non-operable chronic thromboembolic pulmonary hypertension (CTEPH) has recently evolved with the availability of balloon pulmonary angioplasty (BPA) and pulmonary vasodilators. We launched BPA program since 2011. The aim was to analyze survival and treatment efficacy in the modern management era.
Method and result
We retrospectively reviewed data from 143 consecutive CTEPH patients diagnosed in our university from January 2011 (i.e. after the availability of BPA) to December 2019. Forty-one patients underwent PEA, in these 25 patients underwent additional BPA (Hybrid group) and other patients were treated with only PEA (PEA group). Ninety patients underwent BPA (BPA group), remaining 12 patients had not undergone any interventional treatments. The 1- and 5-year survival rates of operated patients (n=41) were 97.4% and 90.0%, compared to96.9% and 86.9% in not-operated patients (n=102), respectively (p=0.579) (Figure). There was no death in Hybrid group. Percent decrease of pulmonary vascular resistance in PEA group, Hybrid group, BPA group were −75.4±9.9%, −74.3±11.8%, −56.3±22.2%, respectively (p<0.01, one-way ANOVA). Absolute decrease of mean pulmonary artery pressure in each groups were −20.3±9.5mmHg, −24.5±8.8mmHg, −16.4±9.2mmHg, respectively (p<0.01, one-way ANOVA).
Conclusion
There was no longer significant difference of long-term survival between operated and not-operated CTEPH. Moreover, Hybrid approach might have the potential to lead notable improvement in the prognosis of CTEPH. BPA and PEA would be mutually complementary therapies in the modern management era.

Abstract
While donor-specific human leukocyte antigen (HLA) antibodies are a frequent cause for chronic antibody-mediated rejection in organ transplantation, this is not the case for antibodies targeting blood group antigens, as ABO-incompatible (ABO-I) organ transplantation has been associated with a favorable graft outcome. Here, we explored the role of CD4 T cell-mediated alloresponses against endothelial HLA-D-related (DR) in the presence of anti-HLA class I or anti-A/B antibodies. CD4 T cells, notably CD45RA-memory CD4 T cells, undergo extensive proliferation in response to endothelial HLA-DR. The CD4 T cell proliferative response was enhanced in the presence of anti-HLA class I, but attenuated in the presence of anti-A/B antibodies. Microarray analysis and molecular profiling demonstrated that the expression of CD274 programmed cell death ligand 1 (PD-L1) increased in response to anti-A/B ligation-mediated extracellular signal-regulated kinase (ERK) inactivation in endothelial cells that were detected even in the presence of interferon-γ stimulation. Anti-PD-1 antibody enhanced CD4 T cell proliferation, and blocked the suppressive effect of the anti-A/B antibodies. Educated CD25+ CD127- regulatory T cells (edu.Tregs ) were more effective at preventing CD4 T cell alloresponses to endothelial cells compared with naive Treg ; anti-A/B antibodies were not involved in the Treg -mediated events. Finally, amplified expression of transcript encoding PD-L1 was observed in biopsy samples from ABO-I renal transplants when compared with those from ABO-identical/compatible transplants. Taken together, our findings identified a possible factor that might prevent graft rejection and thus contribute to a favorable outcome in ABO-I renal transplantation.

Abstract
Setting Four tuberculosis (TB) diagnostic health facilities of the Chongwe District, Zambia. Objective To determine the frequency of bacteriologically confirmed TB patients lost to follow-up (LTFU) before treatment from January to December 2017. Design This is a retrospective cohort study involving the review of TB registers. Information on presumptive TB patients who tested positive either by smear microscopy or Xpert® MTB/RIF assay was extracted from the laboratory TB registers of the TB diagnostic facilities and cross-matched with the TB treatment registers of TB treatment facilities. Results Two hundred and seventeen bacteriologically confirmed TB patients were found in the laboratory TB registers. Of these, 145 (67%) were males and seven (3%) were children; 177 (81%) patients were diagnosed using Xpert, while the remaining 40 (19%) were diagnosed using sputum smear microscopy. A total of 71 (33%) were not linked to treatment. Those diagnosed using smear microscopy were 2.5 times (95% CI 1.1-5.3) more likely to be LTFU before treatment than those diagnosed using Xpert. Conclusion About one third of TB patients who were not linked to treatment could potentially extend the duration of bacilli transmission in their communities. National TB control programmes should consider including LTFU patients before treatment in routine monitoring and evaluation.

Abstract
Abstract
Background
Progression of atherosclerosis is a non-uniform process characterized by coexistence of normal vessel wall (NVW) and advanced fibroatheroma within the same cross-section (Figure). Plaque progression from NVW to fibroatheroma usually takes years, that has never been investigated in human.
Purpose
To investigate the incidence and related factors associated with atherosclerotic progression from NVW to fibroatheroma using long-term serial optical coherence tomography (OCT) follow-up data over 5 years.
Methods
We enrolled 47 vessels in 30 patients who had undergone serial OCT imaging over 5 years (average: 6.8 years). Baseline and follow-up OCT images were matched for longitudinal and circumferential location and OCT cross-sections that had NVW >30 degrees were enrolled. NVW was defined as vessel wall having OCT-detectable three-layer structure with intimal thickening ≤300μm. Cross-sections were diagnosed as +Progression when NVW in the cross-section reduced by >30 degrees during >5-year follow-up.
Results
In the present study, atherogenic progression from NVW to fibroatheroma was observed only in 37.2% of the enrolled cross-sections. On the other hand, despite an average long-term follow-up period of 6.8 years, the extent of NVW was maintained in 62.8% of cross-sections. The incidence of microchannel in adjacent fibroatheroma within the same cross-section (23.6% vs. 13.1%, p=0.023), eccentric plaque distribution (21.7% vs. 11.4%, p=0.019), and concave shape (6.6% vs. 0%, p=0.001) at baseline was significantly higher in cross-sections with +Progression than those without Progression. Average intimal thickness of NVW (187.2±64.9μm vs. 170.7±68.6μm; p=0.048) at baseline was significantly thicker in cross-sections with +Progression than those without. Multivariate analysis demonstrated that the presence of microchannel, eccentric plaque distribution and thicker average intimal thickness of NVW at baseline were independently associated with plaque progression during the follow-up.
Atheroma progression
Conclusion
The presence of microchannel in adjacent fibroatheroma, eccentric plaque distribution, and thicker intimal thickening of NVW were potentially associated with plaque progression from NVW to fibroatheroma.

Abstract
Abstract
Background
The existence of microvasculopathy in patients with chronic thromboembolic pulmonary hypertension (CTEPH) had been suggested. However, the impact of microvasculopathy for pathophysiology had been unknown. Recently dual-energy CT (DECT) can produce a sensitive iodine distribution map as blood perfusion in lung fields to quantify lung perfusion, also can suggest the existence of microvasculopathy according to poor subpleural perfusion which was published previously.
Methods
We retrospectively reviewed poor subpleural perfusion (defined as subpleural spaces either not or minimally perfused in all segments) and hemodynamics of 83 treatment-naïve CTEPH patients who underwent DECT from February 2014 to Jan 2019. Patients were divided according to poor subpleural perfusion: a microvasculopathy group (n=44) or a non-microvasculopathy group (n=39).
We assessed cardiopulmonary exercise test, right heart catheterization and DECT parameters as quantitative evaluation of pulmonary blood volume (PBV). PBV was calculated as the average of entire lung iodine density.
Results
PBV value in non-microvasculopathy group showed significant inverse correlation with pulmonary vascular resistance (PVR) (y = 14236 x-1.028 r=−0.530, p<0.01).
PBV, SvO2, and %DLCO/VA were significantly lower (22.0 vs. 26.4, p<0.01, 61.3 vs. 66.0, p<0.01, and 59.2 vs 75.9 p<0.01), and systolic pulmonary arterial pressure, PVR, VE/VCO2 slope, BNP were higher (69.3 vs 60.6 p=0.04, 834 vs 586 p<0.01, 45.5 vs. 37.8, p=0.02, and 440 vs 122 p=0.04) in microvasculopathy group, while the other parameters were similar between the two groups.
Multivariate analysis revealed that %DLCO/VA was the only predictor of microvasculopathy (OR,0.895 [95% CI, 0.835 - 0.960]; P<0.01).
Conclusion
Pulmonary blood flow of patients in non-micorvasculopathy group showed inverse correlation with PVR. DECT was effective to assess the microvasculopathy in CTEPH. In our experience, less than 60% of non-operable CTEPH patients have microvasculopathy.

Abstract
Abstract
Background
Chronic thromboembolic disease (CTED) is characterised by thromboembolic stenosis and obstruction of pulmonary arteries without pulmonary hypertension. The treatment approach for symptomatic patients with CTED is still controversial. It has been reported the efficacy of surgical endarterectomy for patients with CTED, however that of balloon pulmonary angioplasty (BPA) for non-operable CTED has not been well established.
Method
We started aggressive BPA protocol for non-operable CTED patients who suffered from symptom with NYHA class II, III, and IV or limitation of exercise in spite of mean pulmonary artery pressure (mPAP) <25 mmHg since February 2014. We evaluated subjective symptoms, hemodynamic parameters by right heart catheter, and exercise capacity by cardiopulmonary exercise test at baseline and after the last BPA session.
Results
Twenty-three patients with CTED (68.7±10.5 years-old, 7 male) had undergone BPA. In these, 7 patients had received pulmonary vasodilators previously. After 2.9±1.3 sessions of BPA, Further improvement was observed in hemodynamics such as mPAP (21.6±2.3 to 17.1±2.6 mmHg, p<0.01), pulmonary vascular resistance (278±80 to 198±63 dyne/s/cm–5, p<0.01), which were accompanied with improved peak VO2 (14.6±4.4 to 17.4±4.2 ml/min/kg, p<0.01), VE/VCO2 slope (39.6±14.6 to 30.2±6.0, p=0.01), and functional class (I/II/III/IV; 0/10/12/1 to 9/12/2/0, p<0.01) (Table). All patients were tolerable, and no severe complication regarding to BPA.
Table 1 Variables Baseline After BPA (3 month) P value NYHA class (I / II / III / IV) 0 / 10 / 12 / 1 9 / 12 / 2 / 0 <0.01 Mean PAP (mmHg) 21.6±2.3 17.1±2.6 <0.01 PVR (dyne/sec/cm–5) 278±80 198±63 <0.01 6 MWD (m) 354±93 382±96 0.09 Peak VO2 (ml/min/kg) 14.6±4.4 17.4±4.2 <0.01
Conclusion
BPA may have the potential to achieve further improvement of exercise capacity and symptoms in CTED patients with acceptable risk, therefore BPA should be considered as a treatment option for symptomatic patients with non-operable CTED.

Abstract
To investigate the epidemiologic aspects of colibacillosis in broiler chickens, 83 Escherichia coli isolates obtained from the pericarditis and perihepatitis lesions in broiler chickens from 4 commercial farms, 5 isolates recovered from 5 samples of yolk sac contents that were pooled from 25 emaciated chicks, and 4 fecal isolates obtained from a hatchery that supplied chicks to the 4 commercial farms mentioned above were genetically and bacteriologically characterized. Using pulsed-field gel electrophoresis (PFGE), a total of 92 isolates were classified into 33 pulsotypes. Identical pulsotypes were observed in isolates obtained from hatchery samples and the affected broiler chickens on multiple farms at various sampling times. Seventeen representative isolates with no common origin belonging to 6 pulsotypes and an additional 27 isolates with the other pulsotypes were used for further experiments. Isolates with identical pulsotypes exhibited common traits for virulence-associated genes, lipopolysaccharide core types, and phylogenetic groups. Nine of the isolates were serologically typed as O125 with various types of H antigens and 3 were typed as O25:H4. In the 27 isolates resistant to ceftiofur (CTF), which is a third generation cephalosporin, the blaCTX-M-2, blaCMY-2, blaCTX-M-14, blaCTX-M-65 genes were found in 15, 8, 3, and 1 isolate(s), respectively, and another isolate resistant to CTF had both the blaCTX-M-2 and the blaCMY-2 genes. In the 16 isolates with the blaCTX-M-2 gene, the chromosomal location of the gene was identified in 12 isolates. The plasmid-mediated quinolone resistance genes, oqxAB and aac(6')-Ib-cr, were found in 2 and 3 isolates, respectively. Conjugation experiments revealed that the blaCTX-M-2 (4 isolates), blaCTX-M-14 (3 isolates), blaSHV-12 (1 isolate), and oqxAB (2 isolates) genes were transferred. Our data suggest that E. coli strains with identical pulsotypes had been caused the incidences of colibacillosis and that the antimicrobial resistance genes on conjugative plasmids and those integrated into the chromosome may be spread among avian pathogenic E. coli strains in multiple farms.

Abstract
INTRODUCTION Lymphatic leakage after kidney transplantation is a relatively frequent complication but sometimes resistant to treatment, and there is no fixed treatment algorithm. The effectiveness of therapeutic lymphangiography for postoperative lymphatic or chyle leakage has been reported, but few reports are available regarding patients who have undergone kidney transplantation. In this study, we report our experience with lymphangiography as a therapeutic tool for lymphatic leakage after kidney transplantation. PATIENTS AND METHODS Intranodal lymphangiography for lymphatic leakage was performed in 4 patients (3 male, 1 female; age range, 38 to 70 years old) after living kidney transplantation at the Osaka City University Hospital in Japan. The amount of drainage before lymphangiography was 169 to 361 mL/day. The procedure for intranodal lymphangiography was as follows: the inguinal lymph node was punctured under ultrasound guidance, and the tip of the needle was instilled at the junction between the cortex and the hilum, after which Lipiodol was slowly and manually injected. RESULTS Lymphangiography was technically successful in 3 out of the 4 patients. In all successful cases, the amount of drainage decreased and leakage finally stopped without additional therapy such as sclerotherapy or fenestration. In 2 cases, we were able to directly detect the leakage site using lymphangiography. The time between lymphangiography and leakage resolution ranged from 8 to 13 days. There were neither complications of lymphangiography nor recurrence of lymphatic leakage in the successful cases. CONCLUSIONS Intranodal lymphangiography may be not only a diagnostic tool but also an effective, minimally-invasive, and safe method for treatment of lymphatic leakage resistant to drainage after kidney transplantation.

Abstract
Micro pixel chambers (μ-PIC) are gaseous two-dimensional imaging detectors originally manufactured using printed circuit board (PCB) technology. They are used in MeV gamma-ray astronomy, medicalimaging, neutron imaging, the search for dark matter, and dose monitoring. The position resolution of the present μ-PIC is approximately 120 μm (RMS), however some applications require a fine position resolution of less than 100 μm. To this end, we have started to develop a μ-PIC based on micro electro mechanical system (MEMS) technology, which provides better manufacturing accuracy than PCB technology. Our simulation predicted the gains of MEMS μ-PICs to be twice those of PCB μ-PICs at the same anode voltage. We manufactured two MEMS μ-PICs and tested them to study their behavior. In these experiments, we successfully operated the fabricatedMEMS μ-PICs and we achieved a maximum gain of approximately 7×103 and collected their energy spectra under irradiation of X-rays from 55Fe. However, the measured gains of the MEMS μ-PICs were less than half of the values predicted in the simulations. We postulated that the gains of the MEMS μ-PICs are diminished by the effect of the silicon used as a semiconducting substrate.

Abstract
BACKGROUND The Fukushima Daiichi and Daini Nuclear Power Plant workers experienced multiple stressors as both victims and onsite workers after the 2011 Great East Japan Earthquake and subsequent nuclear accidents. Previous studies found that disaster-related exposures, including discrimination/slurs, were associated with their mental health. Their long-term impact has yet to be investigated. METHOD A total of 968 plant workers (Daiichi, n = 571; Daini, n = 397) completed self-written questionnaires 2-3 months (time 1) and 14-15 months (time 2) after the disaster (response rate 55.0%). Sociodemographics, disaster-related experiences, and peritraumatic distress were assessed at time 1. At time 1 and time 2, general psychological distress (GPD) and post-traumatic stress response (PTSR) were measured, respectively, using the K6 scale and Impact of Event Scale Revised. We examined multivariate covariates of time 2 GPD and PTSR, adjusting for autocorrelations in the hierarchical multiple regression analyses. RESULTS Higher GPD at time 2 was predicted by higher GPD at time 1 (β = 0.491, p < 0.001) and discrimination/slurs experiences at time 1 (β = 0.065, p = 0.025, adjusted R 2 = 0.24). Higher PTSR at time 2 was predicted with higher PTSR at time 1 (β = 0.548, p < 0.001), higher age (β = 0.085, p = 0.005), and discrimination/slurs experiences at time 1 (β = 0.079, p = 0.003, adjusted R 2 = 0.36). CONCLUSIONS Higher GPD at time 2 was predicted by higher GPD and discrimination/slurs experience at time 1. Higher PTSR at time 2 was predicted by higher PTSR, higher age, and discrimination/slurs experience at time 1.

Abstract
The usefulness and limitation of digital subtraction angiography (DSA) in Takayasu arteritis were investigated in 32 patients. Intravenous DSA was particularly useful in the follow-up of patients with an established diagnosis of Takayasu arteritis. Pulmonary arterial involvement could also be demonstrated with intravenous DSA as obstructive arterial changes and lack of accumulation of contrast medium in the pulmonary parenchyma. Detailed information concerning the site and extent of vascular involvement and development of collateral vessels were obtained with intraarterial DSA. Thickening of the thoracic aortic wall, however, could not be recognized with either intravenous or intraarterial DSA. Conventional angiography of the descending thoracic aorta is still required as an initial examination, particularly when there is no aortic arch involvement. However, there is no doubt that DSA has the potential to become the diagnostic procedure of choice in Takayasu arteritis.

Abstract
Methamphetamine (METH)-induced neurotoxicity is associated with mitochondrial dysfunction and enhanced oxidative stress. The aims of the present study conducted in the mouse brain repetitively treated with METH were to (1) examine the redox status using the redox-sensitive imaging probe 3-methoxycarbonyl-2,2,5,5-tetramethylpiperidine-1-oxyl (MCP) and (2) non-invasively visualize the brain redox status with electron paramagnetic resonance (EPR) imaging. The rate of reduction of MCP was measured from a series of temporal EPR images of mouse heads, and this rate was used to construct a two-dimensional map of rate constants called a "redox map." The obtained redox map clearly illustrated the change in redox balance in the METH-treated mouse brain that is a known result of oxidative damage. Biochemical assays also showed that the level of thiobarbituric acid-reactive substance, an index of lipid peroxidation, was increased in mouse brains by METH. The enhanced reduction in MCP observed in mouse brains was remarkably suppressed by treatment with the dopamine synthase inhibitor, α-methyl-p-tyrosine, suggesting that enhancement of the reduction reaction of MCP resulted from enzymatic reduction in the mitochondrial respiratory chain. Furthermore, magnetic resonance imaging (MRI) of METH-treated mice using a blood-brain barrier (BBB)-impermeable paramagnetic contrast agent revealed BBB dysfunction after treatment with METH for 7 days. MRI also indicated that the impaired BBB recovered after withdrawal of METH. EPR imaging and MRI are useful tools not only for following changes in the redox status and BBB dysfunction in mouse brains repeatedly administered METH, but also for tracing the drug effect after withdrawal of METH.

Abstract
OBJECTIVE To evaluate the role of diffusion-weighted MRI (DW-MRI) as an imaging biomarker for upper urinary tract cancer (UUTC) that has already metastasized or will metastasize soon. METHODS 61 patients clinically diagnosed with UUTC were prospectively enrolled in this study. All the patients underwent MRI, including DW-MRI, prior to any interventions. Correlations between apparent diffusion coefficient (ADC) and other clinicopathological variables, including metastasis-free survival, were analysed. RESULTS Median follow-up period was 938 days. Of the 61 patients, 12 had any metastases at the initial diagnosis. 11 patients developed metastases during the follow-up period. These 23 patients were categorized as "Metastatic". Of the remaining 38 patients, 35 with a follow-up period longer than 400 days were categorized as "Localized". ADC was significantly lower in the Metastatic category than in the Localized (p = 0.0002) category. Multivariate analysis of pre-operative variables identified ADC (cut-off value, 1.08 × 10(-3) mm(2) s(-1)) and clinical T stage based on T2 weighted MRI as an independent predictive factor of metastatic UUTC. 46 patients without any metastases during the initial diagnosis were stratified into a high-risk group (16 patients with low ADC and clinical T3-4) and a low-risk group (30 patients with high ADC or clinical Ta-2). The 3-year metastasis-free survivals were 45% and 93%, respectively. CONCLUSION In the current study, UUTC with lower ADC value is more likely to have metastatic potential. Incorporating ADC with clinical T stage helps to differentiate metastatic UUTC at the initial diagnosis. ADVANCES IN KNOWLEDGE DW-MRI is a potential imaging biomarker reflecting metastatic propensity of UUTC.
