disease, and mental disorders later in life. Investigation of the parallel effects of a defined exercise
program on cardiometabolic and mental health in children with overweight or obesity may provide
new insights on the potential benefits of exercise on overall health.
OBJECTIVE To investigate the effects of a 20-week exercise program on cardiometabolic and
mental health in children with overweight or obesity.
DESIGN, SETTING, AND PARTICIPANTS This secondary analysis of a parallel-group randomized
clinical trial was conducted in Granada, Spain, from November 1, 2014, to June 30, 2016. Data
analyses were performed between February 1, 2020, and July 14, 2022. Children with overweight or
obesity aged 8 to 11 years were eligible, and the study was performed in an out-of-school context.
INTERVENTION The exercise program included 3 to 5 sessions/wk (90 min/session) of aerobic plus
resistance training for 20 weeks. The wait-list control group continued with their usual routines.
MAIN OUTCOMES AND MEASURES Cardiometabolic outcomes as specified in the trial protocol
included body composition (fat mass, fat-free mass, and visceral adipose tissue), physical fitness
(cardiorespiratory, speed-agility, and muscular), and traditional risk factors (waist circumference,
blood lipid levels, glucose levels, insulin levels, and blood pressure). Cardiometabolic risk score (z
score) was calculated based on age and sex reference values for levels of triglycerides, inverted high-
density lipoprotein cholesterol, and glucose, the mean of systolic and diastolic blood pressure, and
waist circumference. An additional cardiometabolic risk score also included cardiorespiratory fitness.
Mental health outcomes included an array of psychological well-being and ill-being indicators.
RESULTS The 92 participants included in the per-protocol analyses (36 girls [39%] and 56 boys
[61%]) had a mean (SD) age of 10.0 (1.1) years. The exercise program reduced the cardiometabolic risk
score by approximately 0.38 (95% CI, −0.74 to −0.02) SDs; decreased low-density lipoprotein
cholesterol level by −7.00 (95% CI, −14.27 to 0.37) mg/dL (to convert to mmol/L, multiply by
0.0259), body mass index (calculated as weight in kilograms divided by height in meters squared) by
−0.59 (95% CI, −1.06 to −0.12), fat mass index by −0.67 (95% CI, −1.01 to −0.33), and visceral adipose
tissue by −31.44 (95% CI, −58.99 to −3.90) g; and improved cardiorespiratory fitness by 2.75 (95%
CI, 0.22-5.28) laps in the exercise group compared with the control group. No effects were observed
on mental health outcomes.
CONCLUSIONS AND RELEVANCE In this secondary analysis of a randomized clinical trial, an aerobic
plus resistance exercise program improved cardiometabolic health in children with overweight or
obesity but had no effect on mental health.Spanish Ministry of Economy and Competitiveness DEP2013-47540, DEP2016-79512-R, DEP2017-91544-EXP, and RYC-2011-09011Fondo Europeo de Desarrollo Regional (FEDER)MCIN/AEI /10.13039/501100011033: PID2020-120249RB-I00Andalusian Operational Programme B-CTS-355-UGR18European Regional Development Fund (FEDER in Spanish)Spanish Ministry of Science and Innovation FJC2018-037925-IEuropean Union’s Horizon 2020 research and innovation programme Marie Sklodowska Curie 101028929Spanish Ministry of Education, Culture and Sport FPU15/02645Swedish Research Council for Health, Working Life and Welfare 2012–00036Spanish Ministry of Science, Innovation and Universities FPU17/04802Ramón Areces Foundation DEP2017-91544-EXPAlicia Koplowitz Foundation ALICIAK-2018University of GranadaJunta de AndalucíaEXERNET Research Network on Exercise and Health in Special Populations DEP2005-00046/ACTIInstituto de Salud Carlos III: CB22/03/00058Ministerio de Ciencia e Innovación and Unión Europea–European Regional Development Fun
Association between ribs shape and pulmonary function in patients with Osteogenesis Imperfecta
The aim of the present study was to test the hypothesis that ribs shape changes in patients with OI are
more relevant for respiratory function than thoracic spine shape. We used 3D geometric morphometrics
to quantify rib cage morphology in OI patients and controls, and to investigate its relationship with forced
vital capacity (FVC) and forced expiratory volume in 1 s (FEV1), expressed as absolute value and as percentage
of predicted value (% pred). Regression analyses on the full sample showed a significant relation
between rib shape and FEV1, FVC and FVC % pred whereas thoracic spine shape was not related to any
parameter. Subsequent regression analyses on OI patients confirmed significant relations between
dynamic lung volumes and rib shape changes. Lower FVC and FEV1 values are identified in OI patients
that present more horizontally aligned ribs, a greater antero-posterior depth due to extreme transverse
curve at rib angles and a strong spine invagination, greater asymmetry, and a vertically short, thoracolumbar
spine, which is relatively straight in at levels 1–8 and shows a marked kyphosis in the
thoraco-lumbar transition. Our research seems to support that ribs shape is more relevant for ventilator mechanics in OI patients than the spine shapeThis project was funded by grants of the Fundacion Eresa (grant

COVID-19 Severity and Survival over Time in Patients with Hematologic Malignancies: A Population-Based Registry Study
Mortality rates for COVID-19 have declined over time in the general population, but data in patients with hematologic malignancies are contradictory. We identified independent prognostic factors for COVID-19 severity and survival in unvaccinated patients with hematologic malignancies, compared mortality rates over time and versus non-cancer inpatients, and investigated post COVID-19 condition. Data were analyzed from 1166 consecutive, eligible patients with hematologic malignancies from the population-based HEMATO-MADRID registry, Spain, with COVID-19 prior to vaccination roll-out, stratified into early (February–June 2020; n = 769 (66%)) and later (July 2020–February 2021; n = 397 (34%)) cohorts. Propensity-score matched non-cancer patients were identified from the SEMI-COVID registry. A lower proportion of patients were hospitalized in the later waves (54.2%) compared to the earlier (88.6%), OR 0.15, 95%CI 0.11–0.20. The proportion of hospitalized patients admitted to the ICU was higher in the later cohort (103/215, 47.9%) compared with the early cohort (170/681, 25.0%, 2.77; 2.01–3.82). The reduced 30-day mortality between early and later cohorts of non-cancer inpatients (29.6% vs. 12.6%, OR 0.34; 0.22–0.53) was not paralleled in inpatients with hematologic malignancies (32.3% vs. 34.8%, OR 1.12; 0.81–1.5). Among evaluable patients, 27.3% had post COVID-19 condition. These findings will help inform evidence-based preventive and therapeutic strategies for patients with hematologic malignancies and COVID-19 diagnosis.Depto. de MedicinaFac. de MedicinaTRUEFundación Madrileña de Hematología y HemoterapiaFundación Leucemia y LinfomaAsociación Madrileña de Hematología y Hemoterapiapu
Estimación del movimiento coherente: computación evolutiva como alternativa al annealing determinista
Comunicación presentada en SCETA, Seminario Sobre Computación Evolutiva, celebrado en la VII Conferencia de la Asociación Española para la Inteligencia Artificial, CAEPIA, Málaga, 12-14 noviembre 1997.En este trabajo teórico formulamos soluciones al problema de la Estimación del Movimiento Coherente tomando como referencia funciones de coste que integran variables binarias de decisión y parámetros continuos. Ello se plantea por un lado desde técnicas basadas en Annealing Determinista, y por otro, desde enfoques propios de la Computación Evolutiva. En ambos casos se propone la integración de la búsqueda de variables binarias con el descenso por gradiente en el espacio de parámetros

Robot navigation behaviors based on omnidirectional vision and information theory
In this work we present a reactive autonomous robot navigation system based only on omnidirectional vision. It does not rely on any prior knowledge about the environment apart from assuming a structured one, like indoor corridors or outdoor avenues. The direction of the corridor is estimated from the entropy analysis of a 1-D omnidirectional image. The 2-D omnidirectional image is analyzed for obstacle avoidance and for keeping a safety distance from the borders of the corridor. Both methods are non-metric and no 3-D information is needed. The system performs well with different resolutions and the catadioptric sensor needs no calibration. We present results from indoor and outdoor experiments.This research is funded by the project DPI2005-01280 from the Spanish Government and the project GV06/134 from Generalitat Valenciana (Spain)
