Foram utilizadas a glicemia e a insulina de jejum para cálculo da função das células β pancreáticas (HOMA-%β−Cell) e da resistência à insulina (HOMA-IR e QUICKI) entre os grupos. Analisaram-se, também, variáveis secundárias como idade, idade da menarca, níveis séricos hormonais (testosterona, prolactina, LH e FSH) e de colesterol total, triglicerídeos, HDL colesterol e LDL-colesterol. RESULTADOS: a idade da menarca das pacientes obesas com SOP (11,7±1,8 anos) foi menor que as não-obesas (12,7±1,9) (p<0,05). As SOP obesas tiveram LH inferior (7,9±5,0 mUI/mL) ao valor encontrado nas não-obesas (10,6±6,0 mUI/mL) (p<0,05). Ambos os grupos apresentaram a média de HDL colesterol inferior a 50 mg/dL. As pacientes obesas apresentaram insulina basal (32,5±25,2 mUI/mL) e glicemia de jejum (115,9±40,7 mg/dL) mais elevadas que as não-obesas (8,8±6,6 mUI/mL e 90,2±8,9 mg/dL, respectivamente) (p<0,01). No grupo SOP obesas, a freqüência de resistência à insulina foi de 93 versus 25% no grupo SOP não-obesas (p<0,01). Foi verifi cada hiperfunção das células β do pâncreas em 86% das obesas com SOP contra 41% das não-obesas portadoras de SOP (p<0,0001). CONCLUSÕES: as pacientes com SOP obesas apresentaram freqüência mais alta de resistência à insulina e hiperfunção de células β do pâncreas quando comparadas com pacientes SOP não-obesas.Abstract PURPOSE: to evaluate the effect of obesity on β-cell function in patients with polycystic ovary syndrome (PCOS). METHODS: this cross-section study evaluated 82 patients with PCOS selected consecutively, at the moment of the diagnosis. We compared 31 PCOS obese women (BMI ≥30 kg/m 2 ) to 51 age-matched PCOS nonobese patients (BMI <30 kg/m
Objective: to trace the sociodemographic and clinical profile, causal factors, and therapeutic management provided to children with pressure ulcers during hospitalization. Method: cross-sectional study; retrospective. Sample of 64 medical records of children with PU, admitted to a hospital in southern Brazil, from January/2016 to July/2021. Data analyzed by descriptive and inferential statistics. Results: Profile of children in intensive care (62.5%); stage 1 pressure ulcers (35.9%); and use of simple cover (37.5%). Of the total cases, 25% by medical device use. Consultations were related to stage 3 injury (p=0.027). Nursing diagnosis risk of pressure ulcer was identified in 48.4% of cases, while the Braden/Braden Q scale was identified in 78.1%. Patients classified as high risk (46%) had limited mobility (p=0.000). Conclusions: Pressure ulcers in children in intensive care with limited mobility require everything from simple intervention to consulting according to the classification of the injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
