The Impact of Body Mass Index in Patients with Severe Burn Injury.

This study evaluated the association of body mass index (BMI) with mortality, length of stay in the intensive care unit (ICU), and length of hospital stay in major burn patients. It was a retrospective cohort study that was originally conducted from January 2017 to January 2020 and that used data from patients admitted to the intensive care unit for burns at a university hospital. The patients were divided into groups for the purposes of comparing relevant variables according to their BMI.

Growth hormone directly favors hepatic ketogenesis in persons with prediabetes or type 2 diabetes mellitus treated with empagliflozin.

Purpose: Sodium-glucose cotransporter 2 inhibitors increase glucagon secretion by pancreatic alpha cells and the susceptibility to ketoacidosis. On the other hand, growth hormone (GH) stimulates peripheral lipolysis and provides free fatty acids (FFA) for ketogenesis; however, it remains unresolved whether GH directly impacts hepatic ketogenesis. We aimed to investigate the role of physiologic GH levels in promoting ketogenesis in prediabetic or type 2 diabetic patients under empagliflozin treatment.

Silver serum levels in burned patients treated with silver sulfadiazine and its toxicity on inflammatory cells.

Background: Silver sulfadiazine (SSD) has been widely used in burned patients for the prevention of local infections. To be biologically active and exert antimicrobial properties, silver needs to be present in the form of silver ions (Ag) that bind to negatively charged proteins, namely, the RNA and DNA in microorganisms. However, previous published studies conducted with SSD in the 1990s reported a high level of silver absorption through damaged skin and noted the potential cytotoxicity of Ag to human cells.

Physical Function, Quality of Life, and Energy Expenditure During Activities of Daily Living in Obese, Post-Bariatric Surgery, and Healthy Subjects.

Objectives: This study aimed to evaluate physical function (PF), quality of life (QOL), and energy expenditure (EE) during activities of daily living (ADL) in late outcome post-bariatric surgery (BS) patients and to compare them to severe obese individuals and matched controls.

Methods: Sixty-three subjects were included: 21 patients in post-operative (PO) of BS (3-4 years post-Roux-en-Y gastric bypass) with a stable weight for at least 6 months (16 women, 41 ± 11 years old, BMI = 28 ± 4 kg m) (group PO); 21 obese individuals with BS indication (16 women, 44 ± 9 years old, BMI = 44 ± 6 kg m) (group OB); and 21 controls matched to PO by gender, age, and BMI (16 women, 42 ± 12 years old, BMI = 27 ± 6 kg m) (group MC). PF was objectively assessed by the Glittre and modified Glittre ADL-tests.

A boy with Prader-Willi syndrome: unmasking precocious puberty during growth hormone replacement therapy.

Prader-Willi syndrome (PWS) is a genetic disorder frequently characterized by obesity, growth hormone deficiency, genital abnormalities, and hypogonadotropic hypogonadism. Incomplete or delayed pubertal development as well as premature adrenarche are usually found in PWS, whereas central precocious puberty (CPP) is very rare. This study aimed to report the clinical and biochemical follow-up of a PWS boy with CPP and to discuss the management of pubertal growth.

Clinical, hormonal, ovarian, and genetic aspects of 46,XX patients with congenital adrenal hyperplasia due to CYP17A1 defects.

Objective: To perform a clinical, biochemical, and molecular evaluation of patients with CYP17A1 defects, including ovarian imaging.

Design: Retrospective study.

Setting: Tertiary care center.

Adrenocorticotropic hormone but not high-density lipoprotein cholesterol or salivary cortisol was a predictor of adrenal insufficiency in patients with septic shock.

Relative adrenal insufficiency in sepsis has been extensively debated on; however, accurate diagnosis and therapeutic intervention remain controversial. The authors aimed to evaluate adrenocorticotropic hormone (ACTH), salivary cortisol, total cortisol and estimated plasma-free cortisol, cholesterol, and lipoproteins as predictors of adrenal insufficiency in patients within 24 h of septic shock diagnosis. This prospective study evaluated all hospitalized patients older than 18 years who developed septic shock and were using vasoactive drugs within 24 h of diagnosis.

Impaired antioxidant action of high density lipoprotein in patients with type 1 diabetes with normoalbuminuria and microalbuminuria.

Aims: Patients with type 1 diabetes, in the absence of chronic complications, have serum concentrations of high density lipoprotein cholesterol (HDL-C) similar to the general population. However, their HDL particles may be dysfunctional. We aimed to evaluate the antioxidant effect of HDL2 and HDL3 obtained from Caucasian males with type 1 diabetes with normoalbuminuria and microalbuminuria.

Lipoproteins and CETP levels as risk factors for severe sepsis in hospitalized patients.

Background: The magnitude of lipoprotein level reduction during the acute-phase response may be associated with the severity and mortality of sepsis. However, it remains to be determined whether low lipoprotein levels can be considered a risk factor for developing sepsis. We aimed to investigate lipoprotein levels as risk factors for sepsis in hospitalized patients, and also describe sequential changes in lipoprotein and cholesterol ester transfer protein (CETP) levels during sepsis.

Metformin increases HDL3-cholesterol and decreases subcutaneous truncal fat in nondiabetic patients with HIV-associated lipodystrophy.

The purpose of this study was to assess metformin effects on high-density lipoprotein (HDL) composition of patients with HIV-associated lipodystrophy (LDHIV). Twenty-four adult outpatients were enrolled to receive metformin (1700 mg/d) during 6 months, but 2 were lost to follow-up and 6 stopped the drug due to adverse events (gastrointestinal in 5, and excessive weight loss in 1). From the 16 subjects who completed the study, 69% were female.

Prevalence of metabolic syndrome and associated risk factors in Brazilian schoolchildren.

Objective: To determine the prevalence of metabolic syndrome (MetS) in schoolchildren from 6 to 16 years old, while considering their socio-economic status and other potential risk factors.

Design: A cross-sectional study was conducted between April and November of 2005 in a semi-rural city with a total population of 13,000 inhabitants.

Setting: The study was conducted in Maracai city, located in the Brazilian state of Sao Paulo.

[Prevalence of HIV-associated lipodystrophy in Brazilian outpatients: relation with metabolic syndrome and cardiovascular risk factors].

Lipodystrophy in HIV-infected patients (LDHIV) affects 40-50% of HIV-infected patients, but there are no data on its prevalence in Brazil. The aim of this study was to assess the LDHIV prevalence among HIV-infected adult Brazilian individuals, as well as to evaluate LDHIV association with cardiovascular risk factors and the metabolic syndrome (MS). It was included 180 adult HIV-infected outpatients consecutively seen in the Infectology Clinic of Universidade Estadual de Londrina.

Regulation of hepatic cholesterol metabolism in CETP/LDLr mice by cholesterol feeding and by drugs (cholestyramine and lovastatin) that lower plasma cholesterol.

1. The hepatic mechanisms involved in the simultaneous regulation of plasma cholesterol concentration and cholesteryl ester transfer protein (CETP) activity were investigated by sharply modifying the hepatic rates of cholesterol synthesis. This was accomplished by cholestyramine, lovastatin and cholesterol feeding in human CETP transgenic mice cross-bred with low-density lipoprotein receptor (LDLr)-knockout mice, generating CETP(+/-)/LDLr(+/-) mice, which present a plasma lipoprotein profile resembling that of humans.

[Prevalence of thyroid autoimmunity in a group of patients with type 1 diabetes mellitus in Londrina, PR].

Unlabelled: Thyroid autoimmunity is a frequent comorbid condition subjects with in type 1 diabetes mellitus (DM1). We evaluated the prevalence of antithyroid autoantibodies (antimicrosomal, antithyroglobulin and antithyroid peroxidase), in addition to clinical (gender, age, DM duration) and laboratory (TSH, HbA1) characteristics of 101 patients (mean age 20 +/- 9.6 years; 62 female) followed at the HC/UEL.
