Re: Alemtuzumab-Induced Resolution of Pulmonary Noninfectious Complications in a Patient with Chronic Graft-versus-Host Disease
This study investigated the validation of the psychological resilience scale adaptation from youth development module (RYDM) for secondary school. The psychological RYDM is measured by six factors psychological assets was strongly associated with students academic success. A sample of study is 158 seventh grade students from five secondary schools in Singaraja, Bali Province (75 or 47.4% male and 83 or 52.6% female, with age range 12-13 years). The constructs validation was conduct by exploratory factor analysis (EFA) method, with SPSS 22.0. Five iterations of the EFA reducing 18 original items to 14 items and 6 original factors to 5 factors. Five factors and 14 items produced are consistent with the conceptual basis used in the original RYDM. The stability of new five factors is formed by a split sample analysis method showed the all of the items of factors identified in the earlier testing stable adequacy of forming a common factor in this analysis in the first and second iteration. The results of analysis the item-total correlation on 14 item (n = 158) showed Cronbach's Alpha value of 0.777. Implications the study for guidance and counseling practice in schools is discussed
Physiological responses to acute cold exposure in young lean men
The aim of this study was to comprehensively describe the physiological responses to an
acute bout of mild cold in young lean men (n = 11, age: 23 ± 2 years, body mass index:
23.1 ± 1.2 kg/m2) to better understand the underlying mechanisms of non-shivering thermogenesis
and how it is regulated. Resting energy expenditure, substrate metabolism, skin
temperature, thermal comfort perception, superficial muscle activity, hemodynamics of the
forearm and abdominal regions, and heart rate variability were measured under warm conditions
(22.7 ± 0.2ÊC) and during an individualized cooling protocol (air-conditioning and water
cooling vest) in a cold room (19.4 ± 0.1ÊC). The temperature of the cooling vest started at
16.6ÊC and decreased ~ 1.4ÊC every 10 minutes until participants shivered (93.5 ± 26.3
min). All measurements were analysed across 4 periods: warm period, at 31% and at 64%
of individualÂs cold exposure time until shivering occurred, and at the shivering threshold.
Energy expenditure increased from warm period to 31% of cold exposure by 16.7% (P =
0.078) and to the shivering threshold by 31.7% (P = 0.023). Fat oxidation increased by
72.6% from warm period to 31% of cold exposure (P = 0.004), whereas no changes
occurred in carbohydrates oxidation. As shivering came closer, the skin temperature and
thermal comfort perception decreased (all P<0.05), except in the supraclavicular skin temperature,
which did not change (P>0.05). Furthermore, the superficial muscle activation
increased at the shivering threshold. It is noteworthy that the largest physiological changes
occurred during the first 30 minutes of cold exposure, when the participants felt less
discomfort.The study was supported by the Spanish

Impact of methods for data selection on the day-to-day reproducibility of resting metabolic rate assessed with four different metabolic carts
Background and aims: Accomplishing a high day-to-day reproducibility is important to detect changes in resting metabolic rate (RMR) and respiratory exchange ratio (RER) that may be produced after an intervention or for monitoring patients’ metabolism over time. We aimed to analyze: (i) the influence of different methods for selecting indirect calorimetry data on RMR and RER assessments; and, (ii) whether these methods influence RMR and RER day-to-day reproducibility. Methods and results: Twenty-eight young adults accomplished 4 consecutive RMR assessments (30-min each), using the Q-NRG (Cosmed, Rome, Italy), the Vyntus CPX (Jaeger-CareFusion, Höchberg, Germany), the Omnical (Maastricht Instruments, Maastricht, The Netherlands), and the Ultima CardiO2 (Medgraphics Corporation, St. Paul, Minnesota, USA) carts, on 2 consecutive mornings. Three types of methods were used: (i) short (periods of 5 consecutive minutes; 6e10, 11e15, 16e20, 21e25, and 26e30 min) and long time intervals (TI) methods (6e25 and 6 e30 min); (ii) steady state (SSt methods); and, (iii) methods filtering the data by thresholding from the mean RMR (filtering methods). RMR and RER were similar when using different methods (except RMR for the Vyntus and RER for the Q-NRG). Conversely, using different methods impacted RMR (all P 0.037) and/or RER (P 0.009) day-to-day reproducibility in all carts. The 6e25 min and the 6e30 min long TI methods yielded more reproducible measurements for all metabolic carts.
Conclusion: The 6e25 min and 6e30 min should be the preferred methods for selecting data, as they result in the highest day-to-day reproducibility of RMR and RER assessments.This work was supported by the Spanish Ministry of Economy and Competitiveness via Retos de la Sociedad grant DEP2016-79512-R (to JRR), and European Regional Development Funds (ERDF); Spanish Ministry of Education grant (FPU15/04059 to JMAA; FPU19/01609 to LJ-F; and FPU18/03357 to MD-M); the University of Granada Plan Propio de Investigación 2016-Excellence actions: Unit of Excellence on Exercise and Health (to JRR); the University of Granada Plan Propio 2020 and 2018 Programa Contratos-Puente (to JMA and GS-D, respectively), and Programa Perfeccionamiento de Doctores (to GS-D); Junta de Andalucía, Consejería de Conocimiento, Investigación y Universidades grant SOMM17/6107/UGR (to JRR) via the ERDF; Grant FJC2020-044453-I funded by MCIN/AEI/10.13039/501100011033 and by “European Union NextGenerationEU/PRTR” (to JMA); the Fundación Alfonso Martín Escudero (to GS-D); and a Marie Skłodowska-Curie Actions-Individual Fellowship grant (Horizon2020, 101028941, to GS-D)
The impact of using BARCIST 1.0 criteria on quantification of BAT volume and activity in three independent cohorts of adults
Human brown adipose tissue (BAT) is commonly assessed by cold-induced 18F-fluorodeoxyglucose
(FDG) PET-CT using several quantification criteria. Uniform criteria for data analysis became available
recently (BARCIST 1.0). We compared BAT volume and activity following BARCIST 1.0 criteria
against the most commonly used criteria [Hounsfield Units (HU):-250, -50, standardized uptake
value (SUV):2.0; HU: Not applied, SUV:2.0 and HU:-180, -10, SUV:1.5] in a prospective study using
three independent cohorts of men including young lean adults, young overweight/obese adults and
middle-aged overweight/obese adults. BAT volume was the most variable outcome between criteria.
While BAT volume calculated using the HU: NA; SUV: 2.0 criteria was up to 207% higher than the BAT
volume calculated based on BARCIST 1.0 criteria, it was up to 57% lower using the HU: -250, -50; SUV:
2.0 criteria compared to the BARCIST 1.0. Similarly, BAT activity (expressed as SUVmean) also differed
between different thresholds mainly because SUVmean depends on BAT volume. SUVpeak was the most
consistent BAT outcome across the four study criteria. Of note, we replicated these findings in three
independent cohorts. In conclusion, BAT volume and activity as determined by 18F-FDG-PET/CT highly
depend on the quantification criteria used. Future human BAT studies should conduct sensitivity
analysis with different thresholds in order to understand whether results are driven by the selected HU
and/or SUV thresholds. The design of the present study precludes providing any conclusive threshold,
but before more definitive thresholds for HU and SUV are available, we support the use of BARCIST 1.0
criteria to facilitate interpretation of BAT characteristics between research groups
A larger brown fat volume and lower radiodensity are related to a greater cardiometabolic risk, especially in young men
Objectives: Brown adipose tissue (BAT) is important in the maintenance of cardiometabolic health in rodents. Recent reports appear to suggest the same in humans, although if this is true remains elusive partly because of the methodological bias that affected previous research. This cross-sectional work reports the relationships of cold-induced BAT volume, activity (peak standardized uptake, SUVpeak), and mean radiodensity (an inverse proxy of the triacylglycerols content) with the cardiometabolic and inflammatory profile of 131 young adults, and how these relationships are influenced by sex and body weight.Design: This is a cross-sectional study.Methods: Subjects underwent personalized cold exposure for 2 h to activate BAT, followed by static F-18-fluorodeoxyglucose PET-CT scanning to determine BAT variables. Information on cardiometabolic risk (CMR) and inflammatory markers was gathered, and a CMR score and fatty liver index (FLI) were calculated.Results: In men, BAT volume was positively related to homocysteine and liver damage markers concentrations (independently of BMI and seasonality) and the FLI (all P 0.05).Conclusions: A larger BAT volume and a lower BAT mean radiodensity are related to a higher CMR, especially in young men, which may support that BAT acts as a compensatory organ in states of metabolic disruption.</p
