Unraveling the epidemiology of urinary tract infections in neonates: Perspective from a Brazilian NICU.

BACKGROUND: Urinary tract infections (UTIs) can lead to neonatal complications like sepsis, worsened by empirical treatment, contributing to antimicrobial resistance (AMR). This study examined the incidence, etiology, risk factors, and antimicrobial susceptibility of uropathogens in a Neonatal Intensive Care Unit (NICU) in Brazil. METHODS: Medical records of neonates hospitalized in the NICU from January 2015 to June 2022 were retrospectively analyzed through the National Healthcare Safety Network system. RESULTS: Among 1,474 neonates, 3.9% developed UTI, with an alarming 24-fold increase in incidence from 2015 to 2021. Genitourinary complications (odds ratio = 4.8) were a major risk factor. Of the 71 uropathogens, 74.6% were Gram-negative bacteria (GNB), 21.2% Gram-positive bacteria (GPB), and 4.2% Candida albicans. AMR was notable, with 13.3% of GPB and 20.7% of GNB exhibiting multidrug-resistant (MDR), while 6.6% of GPB and 1.9% of GNB showed extensive drug-resistant (XDR). UTI was associated with prolonged hospitalization (16-59 days). In 57 neonates with UTI, 40.3% had bloodstream infections, elevating the risk of death (odds ratio = 1.8). CONCLUSIONS: The study underscores the urgency of implementing infection prevention and control measures in the NICU to curb rising UTI incidences, combat AMR, and mitigate severe complications in critically ill neonates.

Epidemiological indicators and predictors of lethality associated with fungal infections in a NICU: a historical series.

OBJECTIVES: Fungal infections (FI) pose a public health concern and significantly increase mortality rates, especially within Neonatal Intensive Care Units (NICU). Thus, this study aimed to investigate epidemiological indicators, risk factors, and lethality predictors associated with FI in a NICU. METHODS: This study included 1,510 neonates admitted to the NICU of a reference hospital in Brazil between 2015 and 2022. Demographic data, such as sex, birth weight, gestational age, and use of invasive devices were analyzed. RESULTS: Thirty neonates developed invasive FI, totaling 33 episodes and an incidence of 1.2 per 1,000 patient days. Candida albicans was the most frequent species (52.9 %), the bloodstream was the most affected site (78.9 %), and 72.7 % of infections occurred between 2015 and 2018. The lethality rate associated with FI was 33.3 %, and 90 % of deaths occurred within 30 days of diagnosis of infection. Weight < 750 g, prolonged hospital stay, use of parenteral nutrition, and broad-spectrum antimicrobials were independent risk factors for infection occurrence, especially glycopeptides and 4th generation cephalosporins, having a considerable role in the increase in fungal infections. Weight < 750 g was considered a significant predictor of lethality, and C. albicans had the highest lethality rate (40 %). CONCLUSION: These findings highlight the elevated lethality rate associated with these infections, reinforcing the importance of developing strategies to control FI within NICU.

Impact of intestinal colonization by Gram-negative bacteria on the incidence of bloodstream infections and lethality in critically ill neonates.

BACKGROUND: Early detection of antimicrobial-resistant microorganisms is crucial to prevent subsequent invasive infections and contain their spread in the Neonatal Intensive Care Unit (NICU). This study aims to investigate the association between intestinal colonization (IC) by Gram-negative bacteria and the risk of bloodstream infection (BSI) in critically ill neonates. METHODS: Data from the electronic medical records of 678 newborns admitted to a NICU Brazilian between 2018 and 2022 were retrospectively analyzed. Participants were monitored by the National Health Security Network. RESULTS: Among neonates, 6.9 % had IC (56.9 % attributed to Acinetobacter baumannii); of these, 19.1 % developed BSI (66.7 % by Staphylococcus spp.). Within the A. baumannii colonization, 34.5 % occurred during an outbreak in September 2021. Colonized individuals had a longer mean length of stay (49.3 ± 26.4 days) and higher mortality rate (12.8 %) compared to non-colonized individuals (22.2 ± 16.9 days; 6.7 %, respectively). Previous use of antimicrobials and invasive devices significantly increased the risk of colonization. Colonization by drug-resistant microorganisms, along with the occurrence of BSI, was associated with increased mortality and reduced survival time. CONCLUSIONS: IC contributed to the incidence of BSI, leading to more extended hospital stays and higher mortality rates. Its early detection proved to be essential to identify an outbreak and control the spread of resistant microorganisms within the NICU.

Impact of sickle cell disease on work activity.

Introduction: Sickle cell disease is a group of conditions caused by anomalous hemoglobin that predisposes people to some clinical syndromes. Because of these recurrent syndromes, patients have difficulty finding and, often, keeping a job. Objectives: To evaluate the impact of sickle cell disease on the job situation of people with the condition. Methods: Thirty-two working-age people with sickle cell disease were recruited using the snowball sampling method and underwent semistructured interviews for demographic, socioeconomic, and clinical data collection. Results: Only 28.1% of the interviewees engaged in paid work, 46.9% had already worked but were not working at the time of the interview, and 25% had never worked. About 6% of participants lived in extreme poverty, and 28.4% lived on the poverty line. Monthly per capita income was less than one minimum salary in 56.2% of cases and less than 1.5 minimum salaries in 9.4%. Conclusions: Sickle cell disease has an important negative impact on employment situation, as about 70% of working-age people were inactive. This results in a high social cost represented by a very low monthly per capita income (≤ 1 minimum salary) in 93.7% of the participants.

Cardiovascular and metabolic changes in Brazilian truck drivers.

OBJECTIVE: To identify the relationship between the Ankle Brachial Index (ABI) and the presence of cardio-metabolic diseases, alcohol, and tobacco abuse among truck drivers. METHODS: This is a cross-sectional study with a quantitative approach carried out with 235 truck drivers. Demographic, professional, clinical, alcohol, and tobacco abuse data were collected through interviews. The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) instrument was used for this study. An odds ratio (OR) and 95% confidence interval (95% CI) adjusted for logistic regression were used for the association between variables. The Spearman's test was used to correlate quantitative variables. The significance level used was α = 0.05. RESULTS: The sample consisted of 235 truck drivers, all males, with an average age of 42.4 years, married (69.8%), self-reported white skin color (43.4%). ABI values equal to or less than 0.89 were identified in 38.7% of truck drivers. Tobacco abuse appeared in 18.5% of participants, and alcohol abuse was present in 8.9% of truck drivers according to the ASSIST rating. The most commonly found self-reported cardiometabolic diseases were obesity (29%), systemic arterial hypertension (SAH) (21.7%), and diabetes mellitus (DM) (10.6%). Those with altered ABI had 5.65 times the odds to have self-reported diabetes mellitus (95% CI 2.20-14.52; p = 0.0003), 2.86 times the odds to present alcohol abuse (95% CI 1.03-7.97; p = 0.0400), 3.03 times the odds to have edema (95% CI 1.25-7.36; p = 0.0144) and 5.10 times the odds to have varicose veins in the lower limbs (95% CI 2.22-11.73; p = 0.0001) compared to those with normal ABI values. CONCLUSION: Truck drivers have changes in the ABI which are associated with long working hours, alcohol abuse and the presence of diabetes mellitus.

Inanimate Surfaces and Air Contamination with Multidrug Resistant Species of Staphylococcus in the Neonatal Intensive Care Unit Environment.

BACKGROUND: Contamination of the hospital environment with multi-resistant (MDR) Staphylococcus increases the risk of infection. The aim of this study is to identify the MDR species of Staphylococcus on inanimate surfaces, in air, and in clinical samples, and analyze the risk factors that correlate with the occurrence of infections in a Neonatal Intensive Care Unit. METHODS: Samples of inanimate surfaces and air were taken using a premoistened swab (0.9% sodium chloride) and spontaneous air sedimentation, respectively. The clinical isolates were recovered from infected neonates. The isolates (environmental and clinical) were identified by matrix-assisted laser desorption ionization-time of flight and the resistance profile was calculated using the disk diffusion agar technique. RESULTS: In total, 181 isolates were obtained, 93 from (surfaces), 18 from the air, and 70 clinical samples. S. epidermidis was the most frequent species (66.8%), and the failure rate in air cleaning was 100%. More than 60% of the isolates were MDR, and the majority of clinical isolates (60.4%) had a resistance profile identical to that of the environmental isolates. CONCLUSION: Staphylococcus spp. were found in most of the analyzed samples, with a high frequency of MDR isolates, demonstrating the importance of the hospital environment as a reservoir, and the need for infection control measures, and rational use of antimicrobials.

Hand-foot syndrome and nail disorders secondary to treatment with paclitaxel: Is there a relationship with the presence of fungi?

INTRODUCTION: This study aimed to evaluate the frequency of nail disorders and the presence of fungi on the nails of the hands and feet of patients with hand-foot syndrome secondary to treatment with paclitaxel. METHODS: Prospective study, carried out from October 2018 to December 2019, which included 81 patients undergoing treatment for breast cancer using paclitaxel and had signs and or symptoms of hand-foot syndrome with or without nail disorders. The data were collected through interviews guided by a structured questionnaire, information from medical records and reports of mycological exams. RESULTS: The average age of women was 54.7 ± 7.4 years. Nail disorders occurred in 69 patients (85.2%), and of these, 43 (62.3%) were positive for fungi. The fungi were yeasts (n = 38; 69%), dermatophytes (n = 15; 27.2%) and non-dermatophyte filamentous fungi (n = 8; 14.5%). CONCLUSIONS: Nail disorders were the most frequent manifestations in patients with hand-foot syndrome treated with paclitaxel and occurred in 85.2% of them. It was evidenced that fungi are present on the nails of these patients and can occur in up to 65.28%. The most prevalent fungi were Candida and Trichophyton. The nail lesion was associated with the type of treatment protocol used by the patient. The results of the study point to the need to select safe management alternatives for patients, so they can prevent nail lesions and prevent the proliferation of fungi, consequently reducing negative life impact during treatment.

Quantification of biofilm produced by clinical, environment and hands' isolates Klebsiella species using colorimetric and classical methods.

Some species of Klebsiella, such as Klebsiella pneumoniae and Klebsiella oxytoca, are important nosocomial pathogens frequently involved in outbreaks in Neonatal Intensive Care Units (NICU) and have the ability to form a biofilm. This study aims to evaluate the biofilm production of K. pneumoniae and K. oxytoca isolates collected from the hands of health professionals, neonates' blood and the environment of a Brazilian NICU, using three colorimetric methods and a classical method of counting the colony-forming units and compare the analysis among these techniques. The biofilm formation was carried out by the microplate technique, using three colorimetric assays: crystal violet, safranin and 2,3-bis (2-methoxy-4-nitro-5-sulfophenyl) -5 [(phenylamino) arbonyl] - 2H-tetrazolium hydroxide (XTT). Also, colony-forming units were determined. Twenty-eight isolates of K. pneumoniae were collected from the blood, hands and environment and five of K. oxytoca from the hands and environment. All of them were strong biofilm producers, but K. pneumoniae isolates produced more biofilm than K. oxytoca when compared to the American Type Culture Collection (ATCC) strains used as positive controls. The number of viable cells in the biofilm produced by K. pneumoniae isolated from blood was significantly higher than in the control sample. Regarding the three colorimetric tests used in the study, the violet crystal obtained a higher absorbance average. The use of crystal-violet and XTT in the evaluation of biofilm in vitro make possible a complete analysis, since that it can quantify the total biomass (including the extracellular matrix) and evaluate the metabolic activity. In conclusion, this study identified isolates of K. pneumoniae and K. oxytoca that produce biofilms in the NICU and the bloodstream of neonates. This fact deserves attention since these patients are immunocompromised. The best methods will be chosen to answer research questions by always adopting more than one method so that more than one parameter or component of the biofilm is analyzed.

Association between chronotype and psychomotor performance of rotating shift workers.

It is known that the chronotype potentially mediates the performance and tolerance to work in shifts and that shift rotation is associated with negative effects on psychomotor performance. This study aimed to evaluate the effect of chronotype on psychomotor performance throughout a complete shift rotation schedule. Thirty males working in clockwise rotating shifts from a mining company were evaluated under a real-life condition over the following shift schedule: 2 days of day work, 2 days of evening work and 2 days of night work. The chronotype was determined using the Munich Chronotype Questionnaire adapted for shift workers and the obtained scores were categorized by tertiles (early-type, intermediate-type and late-type). Work performance was evaluated by Psychomotor Vigilance Test (PVT) daily just before shift starts and after shift ends. Sleep duration was evaluated by actigraphy over the whole shift. No isolated effect of the shift or interaction between shift and chronotype was found in the performance variables evaluated. A significant isolated effect of the chronotype showed that the early-type individuals had higher values of pre- and post-work Mean of Reaction Time (MRT) (308.77 ± 10.03 ms and 306.37 ± 8.53 ms, respectively) than the intermediate-type (257.61 ± 6.63 ms and 252.91 ± 5.97 ms, respectively, p < 0.001) and the late-type (273.35 ± 6.96 ms and 262.88 ± 6.05 ms, respectively, p < 0.001). In addition, late individuals presented a greater number of lapses of attention (5.00 ± 0.92; p < 0.05) than early (1.94 ± 0.50, p < 0.05) and intermediate (1.33 ± 0.30, p < 0.001) ones. We concluded that, compared with intermediates, late-type workers had a greater number of lapses of attention on the shift schedule as a whole, while early-type workers showed the highest pre- and post-work MRT. These findings show that the psychomotor performance of rotating shift workers seems to be influenced by the chronotype, but not by the shift rotation.

Time after ostomy surgery and type of treatment are associated with quality of life changes in colorectal cancer patients with colostomy.

PURPOSE: Quality of life in colorectal cancer patients may be affected by colostomy and treatment, but relevant studies are still scarce and contradictory. The present study aimed to evaluate the association between colostomy time and treatment type with quality of life in colorectal cancer patients. METHODS: A prospective observational study of 41 patients with colorectal cancer was conducted on three occasions T0, T1 and T2 (0-2; 3-5 and 6-8 months after ostomy surgery, respectively). The treatments prescribed were: surgery alone, chemotherapy or radiotherapy, or chemoradiotherapy. European Organization for Research and Treatment of Cancer questionnaires were used to evaluate quality of life. Worsening clinical changes were evaluated considering difference in scores between times of surgery ≥±9 points. RESULTS: Regarding ostomy surgery, scores in physical function improved between T0 and T1 and these better scores were maintained at T1 to T2. The same was observed for urinary frequency, appetite loss and dry mouth. Chemoradiotherapy was associated with worse scores for global health status, nausea and vomiting, bloating and dry mouth. Although significant differences were not observed in some domains in the Generalized Estimating Equations analysis, patients showed noticeable changes for the worse in the pain, anxiety, weight concern, flatulence and embarrassment domains during these periods. CONCLUSIONS: Colostomy improved quality of life at 3-5 months in most domains of quality of life and remained better at 6-8 months after surgery. Chemoradiotherapy had a late negative influence on quality of life. Health teams could use these results to reassure patients that this procedure will improve their quality of life in many functional and symptomatic aspects.

Risk factors associated with mortality among patients who had candidemia in a university hospital.

INTRODUCTION: Bloodstream infection due to Candida spp. is a primary cause of morbidity and mortality in tertiary hospitals. METHODS: In this retrospective study, we included patients with a positive blood culture for Candida spp. after 48 h of hospitalization. RESULTS: A total of 335 patients who had candidemia were included in this study. Risk factors associated with mortality were hospitalization in internal medicine units and surgical clinics, age >60 years, mechanical ventilation, orotracheal intubation, hemodialysis, corticosteroids use, and C. parapsilosis infection. CONCLUSIONS: This study highlights the importance of health care related to invasive procedures and actions to improve patient immunity.

Onychomycosis in Psoriatic Patients with Nail Disorders: Aetiological Agents and Immunosuppressive Therapy.

Psoriasis and psoriatic arthritis are chronic, relapsing, immune-based diseases. Psoriatic patients may have nail involvement in 50 to 80% of cases, and this may reach 85% in patients with joint disease, in spite of the fact that the relationship between psoriasis and onychomycosis is not well established. The aim of this study was to investigate the occurrence of onychomycosis in patients with nail disorders and diagnosis of psoriasis and psoriatic arthritis. This was a cross-sectional study in which 38 patients diagnosed with psoriasis and/or psoriatic arthritis were interviewed and had altered nail samples analysed by mycological and histopathological exams. Twenty-two (57.89%) patients had a confirmed diagnosis for onychomycosis. Seventeen (44.8%) had a positive direct mycological examination, 16 (42.1%) had positive cultures, and 12 (31.6%) were positive for fungi by histopathological examination. Dermatophytes were identified in nine (56.3%) cultures, and of these, eight were Trichophyton rubrum and one T. tonsurans. Yeasts were isolated in seven patients (43.75%), which included four Candida parapsilosis and three C. albicans. Six patients (15.78%) were not using immunosuppressive therapy, and the others were using methotrexate, etanercept, adalimumab, infliximab, secukinumab, or golimumab, in monotherapy or in combination with other drugs. The confirmed onychomycosis rate in patients using methotrexate alone was 92.8% (n = 13). We concluded that it is possible that there is a positive relationship between psoriatic disease and onychomycosis. And we highlight that it is also worth investigating in the future the possible role of immunosuppressive therapy (mainly methotrexate) as a predisposing factor for the development of fungal infections in psoriatic patients.

Evaluation of Vulvovaginitis and Hygiene Habits of Women Attended in Primary Health Care Units of the Family.

BACKGROUND: This study aims to investigate the occurrence of vulvovaginal infections, to describe and to relate the hygiene habits of women who were treated at the Units of Primary Attention to Family Health in a municipality in the interior of Brazil. METHODS: This was a cross-sectional study that was carried out in two Primary Health Care Units of the Family of Uberlândia, Minas Gerais, Brazil. The population sample consisted of 100 women who underwent gynecological consultation in the health units. Data were collected through interviews and by the analysis of medical records. Results were reported according to laboratory reports. RESULTS: The participants' ages ranged from 18 to 45 years, with a median of 36 years. Thirty women (30%) presented alterations in the microbiota from a Pap smear, where bacterial vaginosis (diagnosed with Amsel criteria) was the predominant microorganism (83.3%). More than half of the women in the study who had vulvovaginitis wore cotton panties (70%, p = 0.651) and tight jeans/pants (83.3%, p = 0.010). The habit of depilating the genital area was reported by all the women, with the razor blade being the most commonly used tool (68%; p = 0.196). CONCLUSION: Bacterial vaginosis was the most commonly reported infection in the cytological exams. Care with genitalia and genital hygiene habits may be associated with the occurrence of vulvovaginitis.

Candidemia by Candida parapsilosis in a neonatal intensive care unit: human and environmental reservoirs, virulence factors, and antifungal susceptibility.

The Candida parapsilosis complex has emerged as one of the main causes of candidemia worldwide. This study aims to evaluate possible C. parapsilosis sensu stricto reservoirs in a NICU, the expression of virulence factors, and antifungal susceptibility, and to analyze their genetic and phenotypic similarity. The study included 17 isolates of C. parapsilosis: seven environmental, one from a newborn's mother, and nine samples from six newborns. We used molecular and phenotypic tests to characterize the isolates and to trace possible routes of infection. The genetic similarity was determined by random amplified polymorphic DNA. The hemolytic and DNAse activity was determined using sheep's blood and DNAse agar, biofilm production by XTT method, and the susceptibility to antifungals through microdilution methodology. Two environmental strains isolated in the same month had high similarity. The 17 isolates expressed at least one of the three virulence factors studied, and one environmental isolate was resistant to fluconazole. This study shows that environmental contamination can be an important reservoir of potentially pathogenic microorganisms, since isolates of C. parapsilosis sensu stricto collected from the hospital environment were able to express virulence factors. Therefore, we emphasized the importance of determining the transmission routes in NICU in order to detect pathogen sources and reservoirs, as well as to establish prevention measures, such as adequate disinfection of the environment.

ABSTRACT Congenital heart defects (CHD) are among the main causes of morbidity and mortality in infants who has this impairment may present delays in neuropsychomotor development (NPMD). This study assesses the influence of CHD on NPMD of infants. This is an observational study assessing neuropsychomotor development performed by Bayley Scales of Infant and Toddler Development - BSID-III. The Brazilian Economic Classification Criteria was used to verify the socioeconomic status of the families and also the maternal and infants' clinical conditions were verified in the medical discharge report and in the child's health handbook. For the association between the quantitative and qualitative variables with the NPMD, the Spearman's correlation coefficient and the likelihood ratio test were used. A total of 18 infants were assessed, with a predominance of females (72.2%). Most mothers (47.1%) had complete high school or incomplete higher education, with a mean age of 27.2±5.5 years. There was a correlation between the BSID-III scales and the quantitative variables analyzed: motor scale with weight (p=0.02 and r=0.54) and oxygen therapy (p=0.009 and r=−0.591); besides that, the qualitative variables correlation were: motor scale and socioeconomic condition (p=0.015), motor scale and Interatrial Communication - IAC (p=0.023) and language with IAC scales (p=0.038). CHD influences the delay of NPMD, mainly for motor aspect. Furthermore, weight, diagnosis of IAC, use of oxygen therapy and socioeconomic status were considered the main risk factors for the delay in NPMD.

Risk factors associated with mortality among patients who had candidemia in a university hospital

Abstract INTRODUCTION: Bloodstream infection due to Candida spp. is a primary cause of morbidity and mortality in tertiary hospitals. METHODS: In this retrospective study, we included patients with a positive blood culture for Candida spp. after 48 h of hospitalization. RESULTS A total of 335 patients who had candidemia were included in this study. Risk factors associated with mortality were hospitalization in internal medicine units and surgical clinics, age >60 years, mechanical ventilation, orotracheal intubation, hemodialysis, corticosteroids use, and C. parapsilosis infection. CONCLUSIONS: This study highlights the importance of health care related to invasive procedures and actions to improve patient immunity.

Is it possible to predict parameters of the Oxford classification of primary IgA Nephropathy from clinical laboratory data? Focus on the role of segmental glomerulosclerosis subtypes.

INTRODUCTION: IgA nephropathy (IgAN) is the most common primary glomerulonephritis in the world and has a broad range of histological and clinical manifestations, ranging from morphologically normal to globally sclerotic glomeruli with clinical manifestations varying from isolated hematuria to end stage renal disease. This study aims to assess sensitivity, specificity and accuracy of clinical data at the time of biopsy in predicting 2017 updated Oxford classification parameters and to investigate if subtypes of segmental sclerosis (FSGS) influence clinical presentation. MATERIAL AND METHODS: Renal biopsies from 103 patients with IgAN were analyzed. Oxford classification was updated and FSGS lesions were subclassified. ROC curves, univariate and multivariate logistic regression were used. RESULTS: In Oxford classification, the majority of patients had mesangial hypercellularity in less than a half of glomeruli (M0), did not have endocapillary hypercellularity (E0), had segmental glomerulosclerosis (S1), had interstitial fibrosis and tubular atrophy in more than a half of the sample (T2) and had no crescents (C0). Hypertension increases the chance of M1 in 2.54x (p = 0.02). For each unit of increased creatinine, 2.6x more chances of E1 (p = 0.001). S1 is predicted by proteinuria with 75% sensitivity and 90.9% specificity (p < 0.0001). For each unit of increase in GFR, there is a reduction of 6% in the chance of T2 in relation to T0 (p = 0.0001). If hypertension, there is 5x more chances of T2 than T0 (p = 0.01). For each unit of increase in creatinine, there are 2.8x more chances of crescents- C (p = 0.003). Creatinine also showed 75.8% sensitivity and 75% specificity for prediction of C (p = 0.002). Inversely, for each unit of GFR, the chance of C is reduced by 4% (p = 0.007). Other clinical data related with C are hypertension (p = 0.03) and proteinuria (p = 0.02). To determine the role of FSGS subtypes in clinical presentation, we divided patients in S0 and S1 groups. Proteinuria was the only clinical parameter with significative difference, respectively, 0.3 (0-2.1) and 1.6 (0.02-16.2) g/24 h (p < 0.0001). FSGS subtypes related to proteinuria were cellular (p = 0.03) and peri-hilar (p = 0.02). Subtypes classically related to podocytopathies showed no correlation with clinical data. CONCLUSION: In the future, with noninvasive methods for diagnosis of IgAN, it will be essential to predict Oxford classification parameters using clinical laboratory data for establishment of prognosis and therapeutics. We showed that Oxford classification parameters correspond to some clinical laboratory data, making this approach possible. FSGS lesions not specifically related to podocytopathies may also influence clinical parameters that affect renal disease progression.

Insulin, ghrelin and early return of hunger in women with obesity and polycystic ovary syndrome.

BACKGROUND & AIMS: Women with polycystic ovary syndrome (PCOS) have greater predisposition to obesity, but the mechanisms are still unknown. Hyperinsulinemia, insulin resistance and low levels of ghrelin are common in this group. For the purposes of the present study, it was assumed that such changes could have an influence on hunger. This study aimed to assess the hunger pattern before and after an ad libitum meal and the association between insulin and plasma ghrelin with hunger perception in women with obesity, with and without PCOS. METHOD: This cross-sectional study included 53 women with obesity, 30 with PCOS, and 23 controls (with obesity but without PCOS). Insulin, ghrelin, glucose and subjective ratings of hunger (by 100 mm visual analogue scales) were analyzed in a fasting state, preprandially at 12:00 before the ad libitum meal, and postprandially 15, 45, 75 and 135 min after the beginning of the ad libitum meal. RESULTS: There was a significant increase in hunger one hour after the beginning of the ad libitum meal (75 min) in the PCOS group (p = .01) compared to 15 min, whereas this only occurred after 135 min in the control group (2 h later). The usual energy intake adjusted by the intra-individual variability was higher in the PCOS group than in the control group (2309 ±â€¯461 kcal·d-1 × 2124 ±â€¯480 kcal·d-1; p = .04). The concentrations of insulin and ghrelin, in both preprandial and postprandial periods, were not associated with the perception of hunger. CONCLUSIONS: Women with obesity and PCOS had an earlier return of hunger in the postprandial period after an ad libitum meal, but there was not associated with postprandial ghrelin and insulin levels.
