RESUMO
Healthcare workers (HCWs) are at a high risk for exposure to pathogens in the workplace. The objective of this study was to evaluate HCW adherence to follow-up after occupational exposure to blood and body fluids at a tertiary care university hospital in the city of São Paulo, Brazil. Data were collected from 2102 occupational exposures to blood and body fluids reports, obtained from the Infection Control Division of the Universidade Federal de São Paulo/Escola Paulista de Medicina/Hospital São Paulo, in São Paulo, Brazil, occurring between January of 2005 and December of 2011. To evaluate adherence to post-exposure follow-up among the affected HCWs, we took into consideration follow-up visits for serological testing. For HCWs exposed to materials from source patients infected with human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV), as well as from source patients of unknown serological status, follow-up serological testing was scheduled for 3 and 6 months after the accident. For those exposed to materials from source patients co-infected with HIV and HCV, follow-up evaluations were scheduled for 3, 6, and 12 months after the accident. During the study period, there were 2056 accidental exposures for which data regarding the serology of the source patient were available. Follow-up evaluation of the affected HCW was recommended in 612 (29.8%) of those incidents. After the implementation of a post-exposure protocol involving telephone calls and official letters mailed to the affected HCW, adherence to follow-up increased significantly, from 30.5 to 54.0% (P = 0.028). Adherence was correlated positively with being female (P = 0.009), with the source of the exposure being known (P = 0.026), with the source patient being HIV positive (P = 0.029), and with the HCW having no history of such accidents (P = 0.047). Adherence to the recommended serological testing was better at the evaluation scheduled for 3 months after the exposure (the initial evaluation) than at those scheduled for 6 and 12 months after the exposure (P = 0.004). During the study period, there was one confirmed case of HCW seroconversion to HCV positivity. The establishment of a protocol that involves the immediate supervisor of the affected HCWs, in the formal summoning of those HCWs is necessary in order to increase the rate of adherence to post-exposure follow-up.

Environmental cleaning and disinfection are fundamental health care-associated infection prevention measures. This study aimed to evaluate the disinfection compliance of high-touch surfaces in a COVID-19-only intensive care unit, using a fluorescent marker. It was divided into 3 phases, baseline assessment, educational feedback, and post feedback. Disinfection compliance improved significantly from the first to the third phase, 14.3% to 51.4% (P < .001), respectively.

BACKGROUND: Our objective was to identify central line (CL)-associated bloodstream infections (CLABSI) rates and risk factors in Latin-America. METHODS: From January 1, 2014 to February 10, 2022, we conducted a multinational multicenter prospective cohort study in 58 ICUs of 34 hospitals in 21 cities in 8 Latin American countries (Argentina, Brazil, Colombia, Costa Rica, Dominican Republic, Ecuador, Mexico, Panama). We applied multiple-logistic regression. Outcomes are shown as adjusted-odds ratios (aOR). RESULTS: About 29,385 patients were hospitalized during 92,956 days, acquired 400 CLABSIs, and pooled CLABSI rate was 4.30 CLABSIs per 1,000 CL-days. We analyzed following 10 variables: Gender, age, length of stay (LOS) before CLABSI acquisition, CL-days before CLABSI acquisition, CL-device utilization (DU) ratio, CL-type, tracheostomy use, hospitalization type, intensive care unit (ICU) type, and facility ownership, Following variables were independently associated with CLABSI: LOS before CLABSI acquisition, rising risk 3% daily (aOR=1.03;95%CI=1.02-1.04; P < .0001); number of CL-days before CLABSI acquisition, rising risk 4% per CL-day (aOR=1.04;95%CI=1.03-1.05; P < .0001); publicly-owned facility (aOR=2.33;95%CI=1.79-3.02; P < .0001). ICU with highest risk was medical-surgical (aOR=2.61;95%CI=1.41-4.81; P < .0001). CL with the highest risk were femoral (aOR=2.71;95%CI=1.61-4.55; P < .0001), and internal-jugular (aOR=2.62;95%CI=1.82-3.79; P < .0001). PICC (aOR=1.25;95%CI=0.63-2.51; P = .52) was not associated with CLABSI risk. CONCLUSIONS: Based on these findings it is suggested to focus on reducing LOS, CL-days, using PICC instead of femoral or internal-jugular; and implementing evidence-based CLABSI prevention recommendations.

BACKGROUND: There is an increasing use of daily chlorhexidine gluconate (CHG) bathing to decrease healthcare associated infections (HAI). Daily bathing of patients with CHG has been successfully used to prevent multidrug-resistant organisms (MDROs) HAI in intensive care units (ICU). METHODS: This was a 12-month, single-center, open, cluster randomized trial, conducted at four ICUs of the University Hospital of Universidade Federal de São Paulo, Unifesp, Brazil. ICUs were randomized to either perform daily bathing of the patients with pH neutral soap and water - control units, or daily bathing with 2% CHG detergent solution - intervention units. We evaluated the incidence density rate of central line-associated bloodstream infection (CLABSI), ventilator-associated pneumonia (VAP), catheter associated urinary tract infection (CAUTI), Klebsiella pneumoniae carbapenemase (KPC)-producing enterobacteria HAI, and death in the intervention and control units. RESULTS: A total of 1,640 admissions of 1,487 patients occurred during the study period (41.2% control group, and 58.8% intervention group). Incidence density rates of KPC-producing enterobacteria HAI were 5.01 and 2.25 infections/1000 patient-days in the control units and in the intervention units (p = 0.013) and mortality rates were 28.7% and 18.7% in the control units and in the intervention units (p<0.001), respectively. No difference between groups was observed in CLABSI incidence (p = 0.125), VAP incidence (p = 0.247) and CAUTI incidence (p = 0.435). No serious skin reactions were noted in either study group. Daily 2% CHG detergent solution bathing is a feasible, low cost option for HAI prevention in ICU.

The ideal exercise time of day (ETOD) remains elusive regarding simultaneous effects on health and performance outcomes, especially in women. Purpose: Given known sex differences in response to exercise training, this study quantified health and performance outcomes in separate cohorts of women and men adhering to different ETOD. Methods: Thirty exercise-trained women (BMI = 24 ± 3 kg/m2; 42 ± 8 years) and twenty-six men (BMI = 25.5 ± 3 kg/m2; 45 ± 8 years) were randomized to multimodal ETOD in the morning (0600-0800 h, AM) or evening (1830-2030 h, PM) for 12 weeks and analyzed as separate cohorts. Baseline (week 0) and post (week 12) muscular strength (1-RM bench/leg press), endurance (sit-ups/push-ups) and power (squat jumps, SJ; bench throws, BT), body composition (iDXA; fat mass, FM; abdominal fat, Abfat), systolic/diastolic blood pressure (BP), respiratory exchange ratio (RER), profile of mood states (POMS), and dietary intake were assessed. Results: Twenty-seven women and twenty men completed the 12-week intervention. No differences at baseline existed between groups (AM vs PM) for both women and men cohorts. In women, significant interactions (p < 0.05) existed for 1RM bench (8 ± 2 vs 12 ± 2, ∆kg), pushups (9 ± 1 vs 13 ± 2, ∆reps), BT (10 ± 6 vs 45 ± 28, ∆watts), SJ (135 ± 6 vs 39 ± 8, ∆watts), fat mass (-1.0 ± 0.2 vs -0.3 ± 0.2, ∆kg), Abfat (-2.6 ± 0.3 vs -0.9 ± 0.5, ∆kg), diastolic (-10 ± 1 vs-5 ± 5, ∆mmHg) and systolic (-12.5 ± 2.7 vs 2.3 ± 3, mmHg) BP, AM vs PM, respectively. In men, significant interactions (p < 0.05) existed for systolic BP (-3.5 ± 2.6 vs -14.9 ± 5.1, ∆mmHg), RER (-0.01 ± 0.01 vs -0.06 ± 0.01, ∆VCO2/VO2), and fatigue (-0.8 ± 2 vs -5.9 ± 2, ∆mm), AM vs PM, respectively. Macronutrient intake was similar among AM and PM groups. Conclusion: Morning exercise (AM) reduced abdominal fat and blood pressure and evening exercise (PM) enhanced muscular performance in the women cohort. In the men cohort, PM increased fat oxidation and reduced systolic BP and fatigue. Thus, ETOD may be important to optimize individual exercise-induced health and performance outcomes in physically active individuals and may be independent of macronutrient intake.
RESUMO
BACKGROUND: The International Nosocomial Infection Control Consortium (INICC) has found a high ICU mortality rate in Latin America. METHODS: A prospective cohort study in 198 ICUs of 96 hospitals in 46 cities in 12 Latin American countries to identify mortality risk factors (RF), and data were analyzed using multiple logistic regression. RESULTS: Between 07/01/1998 and 02/12/2022, 71,685 patients, followed during 652,167 patient-days, acquired 4700 HAIs, and 10,890 died. We prospectively collected data of 16 variables. Following 11 independent mortality RFs were identified in multiple logistic regression: ventilator-associated pneumonia (VAP) acquisition (adjusted odds ratio [aOR] = 1.17; 95% CI: 1.06-1.30; p < 0.0001); catheter-associated urinary tract infection (CAUTI) acquisition (aOR = 1.34; 95% CI: 1.15-1.56; p < 0.0001); older age, rising risk 2% yearly (aOR = 1.02; 95% CI: 1.01-1.02; p < 0.0001); longer indwelling central line(CL)-days, rising risk 3% daily (aOR = 1.03; 95% CI: 1.02-1.03; p < 0.0001); longer indwelling urinary catheter(UC)-days, rising risk 1% daily (aOR = 1.01; 95% CI: 1.01-1.26; p < 0.0001); higher mechanical ventilation (MV) (aOR = 6.47; 95% CI: 5.96-7.03; p < 0.0001) and urinary catheter-utilization ratio (aOR = 1.19; 95% CI: 1.11-1.27; p < 0.0001); lower-middle level income country (aOR = 2.94; 95% CI: 2.10-4.12; p < 0.0001); private (aOR = 1.50; 95% CI: 1.27-1.77; p < 0.0001) or public hospital (aOR = 1.47; 95% CI: 1.24-1.74; p < 0.0001) compared with university hospitals; medical hospitalization instead of surgical (aOR = 1.67; 95% CI: 1.59-1.75; p < 0.0001); neurologic ICU (aOR = 4.48; 95% CI: 2.68-7.50; p < 0.0001); adult oncology ICU (aOR = 3.48; 95% CI: 2.14-5.65; p < 0.0001); and others. CONCLUSION: Some of the identified mortality RFs are unlikely to change, such as the income level of the country, facility ownership, hospitalization type, ICU type, and age. But some of the mortality RFs we found can be changed, and efforts should be made to reduce CL-days, UC-days, MV-utilization ratio, UC-utilization ratio, and lower VAPs and CAUTI rates.

OBJECTIVE: The objective of this study was to evaluate the incidence of nosocomial infection and the impact of cross-transmission of SARS-CoV-2 among inpatients at a tertiary care teaching hospital. METHODS: This was a retrospective cohort study involving inpatients admitted to a tertiary university hospital in the city of São Paulo, Brazil, between March 2020 and February 2021. Cases were identified on the basis of a positive reverse-transcription polymerase chain reaction result for SARS-CoV-2 and the review of electronic medical records. Nosocomial transmission was defined by applying the criteria established by the Brazilian National Health Regulatory Agency. RESULTS: We identified 2146 cases of SARS-CoV-2 infection, 185 (8.6%) of which were considered cases of nosocomial transmission. The mean age was 58.3 years. The incidence density was 1.78 cases per 1,000 patient-days on the general wards, being highest on the cardiac surgery ward, and only 0.16 per 1,000 patient-days on the COVID-19 wards. Of the 185 patients evaluated, 115 (62.2%) were men, 150 (81.1%) cases had at least one comorbidity, and 104 (56.2%) evolved to death. CONCLUSIONS: Despite the preventive measures taken, nosocomial transmission of SARS-CoV-2 occurred throughout our hospital. Such measures should be intensified when the incidence of community transmission peaks.

BACKGROUND: Data on short-term peripheral intravenous catheter-related bloodstream infections per 1,000 peripheral venous catheter days (PIVCR BSIs per 1,000 PVC days) rates from Latin America are not available, so they have not been thoroughly studied. METHODS: International Nosocomial Infection Control Consortium (INICC) members conducted a prospective, surveillance study on PIVCR BSIs from January 2010 to March 2018 in 100 intensive care units (ICUs) among 41 hospitals, in 26 cities of 9 countries in Latin America (Argentina, Brazil, Colombia, Costa Rica, Dominican-Republic, Ecuador, Mexico, Panama, and Venezuela). The Centers for Disease Control and Prevention (CDC) National Health Safety Network (NHSN) definitions were applied, and INICC methodology and INICC Surveillance Online System software were used. RESULTS: In total, 10,120 ICU patients were followed for 40,078 bed days and 38,262 PVC days. In addition, 79 PIVCR BSIs were identified, with a rate of 2.06 per 1,000 PVC days (95% confidence interval [CI], 1.635-2.257). The average length of stay (ALOS) of patients without a PIVCR BSI was 3.95 days, and the ALOS was 5.29 days for patients with a PIVCR BSI. The crude extra ALOS was 1.34 days (RR, 1.33; 95% CI, 1.0975-1.6351; P = .040).The mortality rate in patients without PIVCR BSI was 3.67%, and this rate was 6.33% in patients with a PIVCR BSI. The crude extra mortality was 1.70 times higher. The microorganism profile showed 48.5% gram-positive bacteria (coagulase-negative Staphylococci 25.7%) and 48.5% gram-negative bacteria: Acinetobacter spp, Escherichia coli, and Klebsiella spp (8.5% each one), Pseudomonas aeruginosa (5.7%), and Candida spp (2.8%). The resistances of Pseudomonas aeruginosa were 0% to amikacin and 50% to meropenem. The resistance of Acinetobacter baumanii to amikacin was 0%, and the resistance of coagulase-negative Staphylococcus to oxacillin was 75%. CONCLUSIONS: Our PIVCR BSI rates were higher than rates from more economically developed countries and were similar to those of countries with limited resources.

Obesity, insulin resistance, and poor metabolic profile are hallmarks of a high-fat diet (HFD), highlighting the need to understand underlying mechanisms. Therefore, we sought to determine the effect of succinic acid (SA) on metabolism in high-fat diet (HFD)-induced obesity. Animals were randomly assigned to either low-fat diet (LFD) or a high-fat diet (HFD). Mice consumed their respective diets for 4.5 months and then assigned to the following groups: (LFD)+vehicle, LFD + SA (0.75 mg/ml), HFD + vehicle, or HFD + SA. Body weight (BW), food, and water intake, were tracked weekly. After 6 weeks, insulin, glucose, and pyruvate tolerance tests were completed, and spontaneous physical activity was assessed. Epididymal white adipose tissue (EWAT) mass and in vitro measurements of oxidative skeletal muscle (soleus) respiration were obtained. Expectedly, the HFD increased BW and EWAT mass, and reduced glucose and insulin tolerance. SA significantly reduced EWAT mass, more so in HFD (p < .05), but had no effect on any in vivo measurements (BW, insulin, glucose, or pyruvate tolerance, nor physical activity, all p > .05). A significant (p < .05) interaction was observed between mitochondrial respiration and treatment, where SA increased respiration, likely owed to greater mitochondrial content, as assessed by complex IV activity in both LFD and HFD. In HFD-induced obesity, coupled with insulin desensitization, we found no favorable effect of succinic acid on glucose regulation, though adiposity was attenuated. In oxidative skeletal muscle, there was a tendency for increased respiratory capacity, likely owed to greater mitochondrial content, suggestive of a succinic acid-induced mitochondrial biogenesis.

RESUMO
BACKGROUND: An acute bout of eccentric contractions (ECC) cause muscle fiber damage, inflammation, impaired muscle function (MF) and muscle soreness (MS). Individually, protein (PRO) and antioxidant (AO) supplementation may improve some aspects of recovery from ECC, though have yet to be combined. We sought to determine if combined PRO and AO supplementation (PRO + AO) improves MS and MF following damaging ECC over PRO alone. METHODS: Sixty sedentary college-aged males participated in a randomized, single-blind, parallel design study of peak isometric torque (PIMT), peak isokinetic torque (PIKT), thigh circumference (TC), and muscle soreness (MS) of knee extensor muscles measured at baseline, immediately after and 1, 2, 6, and 24 h after completion of 100 maximal ECC. Immediately, 6 h, and 22 h post-ECC, participants consumed either: carbohydrate control (CHO; n = 14), PRO (n = 16), or PRO + AO (n = 17). RESULTS: At baseline MS, TC, MF, macro- and micro-nutrient intakes, and total work during the ECC were not different between groups (p > 0.05). PIMT and PIKT (both -25%∆), TC (~1%∆) and MS (~35%∆) all changed with time (p < 0.05). We observed a group by time effect for PIKT (PRO + AO and PRO > CHO, p < 0.05). At 24 h post ECC, there was a trend towards improved relative PIMT (~11%) and PIKT (~17%) for PRO + AO (~17%) and PRO (~11%) compared to CHO. An interaction indicated PRO + AO had lowest MS over time (PRO + AO > PRO & CHO, p < 0.05). CONCLUSIONS: Our results suggest PRO facilitates recovery of muscle function within 24 h following ECC, and addition of AO ameliorates MS more than PRO or CHO alone.

OBJECTIVE: Protein-pacing (P; 5-6meals/day @ 2.0g/kgBW/day) and multi-mode exercise (RISE; resistance, interval, stretching, endurance) training (PRISE) improves muscular endurance, strength, power and arterial health in exercise-trained women. The current study extends these findings by examining PRISE on fitness, growth hormone (GH), insulin-like growth factor-1 (IGF-1), and brain-derived neurotrophic factor (BDNF) response, cardiometabolic health, and body composition in exercise-trained men. DESIGN: Twenty active males (>4daysexercise/week) completed either: PRISE (n=11) or RISE (5-6meals/day @ 1.0g/kgBW/day; n=9) for 12weeks. Muscular strength (1-repetition maximum bench and leg press, 1-RM BP, and 1-RM LP), endurance (sit-ups, SU; push-ups, PU), power (squat jump, SJ, and bench throw, BT), flexibility (sit-and-reach, SR), aerobic performance (5km cycling time-trial, TT), GH, IGF-1, BDNF, augmentation index, (AIx), and body composition, were assessed at weeks 0 (pre) and 13 (post). RESULTS: At baseline, no differences existed between groups except for GH (RISE, 230±13 vs. PRISE, 382±59pg/ml, p<0.05). The exercise intervention improved 1-RM, SJ, BT, PU, SU, SR, 5km-TT, GH, AIx, BP, and body composition in both groups (time, p<0.05). However, PRISE elicited greater improvements in 1-RM BP (21 vs. 10∆lbs), SJ (171 vs. 13∆W), 5km-TT (-37 vs. -11∆s), and sit-and-reach (5.3 vs. 1.2∆cm) over RISE alone (p<0.05) including increased IGF-1 (12%, p<0.05). CONCLUSIONS: Exercise-trained men consuming a P diet combined with multi-component exercise training (PRISE) enhance muscular power, strength, aerobic performance, and flexibility which are not likely related to GH or BDNF but possibly to IGF-1 response.

The beneficial cardiometabolic and body composition effects of combined protein-pacing (P; 5-6 meals/day at 2.0 g/kg BW/day) and multi-mode exercise (resistance, interval, stretching, endurance; RISE) training (PRISE) in obese adults has previously been established. The current study examines PRISE on physical performance (endurance, strength and power) outcomes in healthy, physically active women. Thirty exercise-trained women (>4 days exercise/week) were randomized to either PRISE (n = 15) or a control (CON, 5-6 meals/day at 1.0 g/kg BW/day; n = 15) for 12 weeks. Muscular strength (1-RM bench press, 1-RM BP) endurance (sit-ups, SUs; push-ups, PUs), power (bench throws, BTs), blood pressure (BP), augmentation index, (AIx), and abdominal fat mass were assessed at Weeks 0 (pre) and 13 (post). At baseline, no differences existed between groups. Following the 12-week intervention, PRISE had greater gains (p < 0.05) in SUs, PUs (6 ± 7 vs. 10 ± 7, 40%; 8 ± 13 vs. 14 ± 12, 43% ∆reps, respectively), BTs (11 ± 35 vs. 44 ± 34, 75% ∆watts), AIx (1 ± 9 vs. -5 ± 11, 120%), and DBP (-5 ± 9 vs. -11 ± 11, 55% ∆mmHg). These findings suggest that combined protein-pacing (P; 5-6 meals/day at 2.0 g/kg BW/day) diet and multi-component exercise (RISE) training (PRISE) enhances muscular endurance, strength, power, and cardiovascular health in exercise-trained, active women.

Los trastornos de la conducta alimentaria (anorexia nerviosa, bulimia nerviosa y trastorno alimentario no especificado) afectan principalmente a adolescentes. Es en este período donde se corren mayores riesgos de desarrollar estos tipos de trastornos que afectan sin importar la edad, sexo, creencia religiosa o nivel socio-económico. Objetivos: determinar cuáles son los riesgos de trastornos en conductas alimentarias en una población mixta del último año del secundario de institutos adventistas en Argentina. Pacientes y métodos: estudio de tipo descriptivo, transversal y retrospectivo. Se realizó a 432 alumnos del último año del secundario, 218 mujeres y 214 varones entre 15 y 20 años, pertenecientes a 18 institutos adventistas de Argentina. Se les aplicó el test EAT-26, y se les preguntó peso y talla para obtener el índice de masa corporal (IMC). Resultados: el 13,7% de la muestra total presentó riesgo de desarrollar algún tipo de trastorno de la conducta alimentaria, siendo el 11,34% en mujeres y el 2,31% en hombres. Conclusiones: se determinó que una proporción significativamente mayor de adolescentes mujeres presentó riesgo de padecer algún trastorno de la conducta alimentaria. No se encontró relación entre la creencia religiosa y su práctica con el riesgo de desarrollar algún tipo de trastorno alimentario. Las mayores preocupaciones que manifestaron los adolescentes fueron: querer estar más delgados, angustia por estar más gordos, pensamiento en las calorías que queman cuando realizan deporte y disgusto por probar nuevos y sabrosos platos.
Eating behavior disorders (anorexia nervosa, bulimia nervo-sa and eating disorder not otherwise specified) mainly affect teenagers. It is in this period of life where greater risk of deve-loping these types of disorders exists, affecting young people regardless of age, sex, creed or socio- economic level. Objectives: to identify risks in eating behavior disorders in a mixed population of senior students of Seventh-day Adven-tist schools in Argentina.Patients and methods: descriptive, cross-sectional and retrospective study. A sample population of 432 Academy senior students were tested, 218 women and 214 men bet-ween 15 and 20 years old, from 18 Seventh-day Adventist schools in Argentina. The EAT-26 test was applied, and they were asked about weight and height to obtain body mass index (BMI). Results: 13,7% of the total sample (11,34% women and 2,31% men) is at risk for some type of eating behavior disorders.Conclusions: it was determined that a significantly higher proportion of female teenagers presented some risk of eating behavior disorders. No relationship between religious belief and practice with the risk of developing some sort of eating disorder was found. Main concerns presented by these ado-lescents were wish to be thinner, anguish related to being fat, concern about the calories you burn when you do sports, and disgust to try new and tasty dishes.

Introducción. Los trastornos alimentarios representan un problema de salud que involucra la conducta alimentaria, el modo y la forma de hacerlo. Una medida para evitar el incremento de la prevalencia de trastornos de este tipo en adolescentes es la implementación de una ley de talles de indumentaria. Objetivos: describir el cumplimiento de la curva de talles en jeans para mujeres adolescentes en locales de indumentaria en la zona comercial de Paraná, según lo indicado en la Ley provincial N° 9703. Evaluar la percepción de las compradoras al momento de adquirir una prenda de vestir, establecer si la disponibilidad de talles ejerce influencia en la decisión de realizar dietas posteriores y determinar cuáles son las reacciones de la población de estudio respecto de la disponibilidad de talles. Materiales y métodos. Estudio descriptivo y de corte transversal. Se realizó un cuestionario con preguntas cerradas en 63 negocios de indumentaria para la mujer y a 91 mujeres adolescentes. Resultados: El 85,7% de las adolescentes refieren que el tamaño de los talles varía según el modelo de indumentaria (clásico y tendencia). El sentimiento más prevalente de las jóvenes cuando no se consigue el talle adecuado es molestia (38,5%) y 61,6% se plantearon realizar dietas hipocalóricas. Se observó una diferencia en centímetros al comparar con las medidas establecidas por las normas IRAM 75300, a mayor número de talle, mayor la diferencia en el tamaño real, especialmente en los talles medios y grandes. Conclusiones: Se halló que hay un cumplimiento parcial de la curva de talles en jeans para mujeres adolescentes, ya que hay talles de jeans pero estos no cumplen con la medida que reglamenta la ley. En las adolescentes no encontrar talles adecuados genera molestia e incentiva la realización de dietas hipocalóricas.
