Contents Plasmatic concentrations of von Willebrand Factor (v WF) increase during pregnancy in humans and dogs; however the mechanism of such increase is still not well defined. The aims of this study were: (i) to evaluate changes in v WF concentration during pregnancy and during the subsequent oestrous cycle in bitches affected and unaffected by von Willebrand Disease (v WD); (ii) to correlate the vWF levels and cortisol levels in both groups. Seven v WD affected ( GI) and nine unaffected ( GII) bitches were used. The animals were assessed during pregnancy, parturition, lactation and non-gestational oestrous cycle in 11 moments (Pregnancy 1, Pregnancy 2, Parturition, Lactation 1, Lactation 2, Lactation 3, Anestrus, Proestrus, Oestrus, Diestrus 1, and Diestrus 2). The following tests were performed; measurement of von Willebrand factor antigen (v WF: Ag), albumin and cortisol. In both groups, v WF concentration remained stable during the non-gestational oestrous cycle, but increased during pregnancy, with the highest value observed at parturition. Increases of 70% and 124% in v WF were seen in GI and GII, respectively, compared to anestrus. No correlation was found between v WF and cortisol. Values of v WF: Ag changed during pregnancy, with a peak at parturition, both in v WD affected and unaffected animals. Values of v WF were not altered in the different phases of the oestrous cycle following pregnancy in both groups. Evaluation of v WF during pregnancy can cause false negative results for v WD, but assessment can be performed at any point in the oestrous cycle of non-pregnant bitches. [ABSTRACT FROM AUTHOR]

AIM: We aim was to compare the sagittal abdominal diameter (SAD) with waist circumference (WC) as a predictor of central obesity among adults and to identify the sensitivity and specificity of the best cut-off point for SAD. METHODS: A cross-sectional study of 266 Brazilians adults (euthrophic and overweight), aged 31-84 years old, of which 89 men and 177 women, was carried out. Anthropometric measurements such as SAD, weight, height, waist and hip circumferences, waist and hip ratio, body mass index, body fat percentage were performed. Receiver Operating Characteristics (ROC) curve was used to identify the sensitivity and specificity of the best cut off point for SAD as a predictor of central obesity. Statistical analysis were considered significant with a value of p < 0.05. RESULTS: The SAD measurement was positively correlated with WC for both genders, although stronger among overweight and obesity women (r = 0.71; p < 0.001 and r = 0.79; p < 0.001, respectively) than men. ROC curves identified the best cut-off points for SAD of 23.1 cm and 20.1 cm for men and women (96% and 85% sensitivity, 86% and 84% specificity, respectively). CONCLUSION: SAD measurement may be used as an anthropometric tool to identify central obesity among women for presenting adequate sensitivity and specificity. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the mechanisms by which the association between maternal hyperglycemia and postnatal high-fat diet (HFD) exposure compromises metabolic parameters and hepatic autophagy in adult female pups. For this, Sprague Dawley rats, female pups from nondiabetic (control = FC) or diabetic (FD) mothers, were fed a standard diet (SD) or HFD from weaning until adulthood ( n minimum = 5 rats/group): FC/SD, FC/HFD, FD/SD, and FD/HFD. In adulthood, these rats were tested with the oral glucose tolerance test, euthanized, and serum biochemistry parameters were analyzed. Liver samples were collected to evaluate cytokines, redox status, and protein expression autophagy and apoptosis markers. Histomorphometric analyses and an assessment of lipofuscin accumulation were also performed to reflect incomplete autolysosomal digestion. The FC/HFD, FD/SD, and FD/HFD groups showed glucose intolerance and an increased number of hepatocytes. Furthermore, FD/SD and FD/HFD rats showed hyperlipidemia and insulin resistance. Adaptations in hepatic redox pathways were observed in the FD/SD group with increased antioxidant defense marker activity. The FD/SD group also exhibited increased autophagy protein expression, such as p-AMPK, LC3-II/LC3-I, and p62/SQSTM1, lipofuscin accumulation, and caspase-3 activation. After exposure to HFD, the adult female pups of diabetic rats had a reduced p-AMPK and LC3-II/LC3-I ratio, the presence of steatosis, oxidative stress, and inflammation. The reduction of autophagy, stimulated by HFD, may be of vital importance for the susceptibility to metabolic dysfunction-associated fatty liver disease induced by maternal diabetes.

Objective: To assess the prevalence of changes on computed tomography (CT) in Graves' orbitopathy (GO) and to correlate those changes with disease activity, as well as with clinical and biochemical variables., Materials and Methods: This was a retrospective study, conducted at a tertiary hospital, of clinical, biochemical, and imaging data from consecutive patients with GO who underwent at least one orbital CT scan between July 2012 and December 2020. A single observer quantified the thickness of the extraocular muscles and the degree of proptosis. Clinical and biochemical variables were analyzed to determine whether they correlated with CT changes, GO activity, and GO severity., Results: Our sample included data from 67 patients with GO (134 orbits), 50 (74.6%) of whom were female. There were positive correlations between the clinical activity score and increase in thyroid-stimulating factor/free thyroxine, between the severity of GO and the increase in the thickness of the extraocular muscles, and between the degree of proptosis and muscle thickness., Conclusion: Orbital CT proved effective in detecting thickening of the extraocular muscles and proptosis in patients with GO, changes that correlated significantly with clinical and biochemical variables. Muscle thickening was associated with the severity of GO and could be a biomarker of the risk of vision loss.

Background: Understanding the timing of food introduction in infants is essential for promoting optimal complementary feeding practices. However, existing studies often rely on cross-sectional data, limiting the ability to capture age-specific patterns. We aimed to describe food introduction during the first year of life by identifying patterns related to age at food introduction and associated factors in a cohort of Brazilian infants., Methods: Data were collected through standardized questionnaires administered to mothers via face-to-face interviews during the infant's first month of life and at 3, 6, 9, and 12 months of age. Additionally, two telephone interviews were conducted at 2 and 4 months of age. Information regarding food intake was assessed using a list of 48 foods, with two key aspects recorded: whether the food was introduced (yes/no) and the age at introduction. To define food introduction patterns, we employed k-means cluster analysis. Hierarchical Poisson multiple regression was employed to examine the associations between sociodemographic, biological, and healthcare factors and patterns of food introduction., Results: Three distinct patterns were identified and named according to their main characteristics: Pattern 1 - "Low Infant Formula and Timely CF Introduction"; Pattern 2 - "High Infant Formula and Early CF Introduction"; and Pattern 3 - "High Infant Formula and Later Ultra-processed Food Introduction". Breastfeeding at six months showed a positive association with Pattern 1 (PR = 1.40; 95% CI = 1.10-1.80), while bottle use at four months was negatively associated with Pattern 1 (PR = 0.68; 95% CI = 0.53-0.87). No variables studied exhibited an association with Pattern 2. For Pattern 3, higher prevalences were observed among children whose mothers were aged < 20 years (PR = 1.54; 95% CI = 1.13-2.01) or > 34 years (PR = 1.42; 95% CI = 1.04-1.93). Not receiving guidance on the recommended duration of breastfeeding and complementary feeding during prenatal care was associated with a higher prevalence of children in this pattern (PR = 1.35; 95% CI = 1.01-1.80)., Conclusions: We identified three distinct patterns of age at food introduction in the study population, although none perfectly aligned with Brazilian or WHO dietary recommendations. These findings underscore the need for targeted interventions to promote timely and healthy complementary feeding practices in Brazilian infants., (© 2024. The Author(s).)

Maternal diabetes may influence glucose metabolism in adult offspring, an area with limited research on underlying mechanisms. Our study explored the impact of maternal hyperglycemia during pregnancy on insulin resistance development. Adult female Sprague-Dawley rats from control and diabetic mothers were mated, and their female offspring were monitored for 150 days. The rats were euthanized for blood and muscle samples. Maternal diabetes led to heightened insulin levels, increased HOMA-IR, elevated triglycerides, and a raised TyG index in adult offspring. Muscle samples showed a decreased protein expression of AMPK, PI3K, MAPK, DRP1, and MFF. These changes induced intergenerational metabolic programming in female pups, resulting in insulin resistance, dyslipidemia, and glucose intolerance by day 150. Findings highlight the offspring's adaptation to maternal hyperglycemia, involving insulin resistance, metabolic alterations, the downregulation of insulin signaling sensors, and disturbed mitochondrial morphology. Maintaining maternal glycemic control emerges as crucial in mitigating diabetes-associated disorders in adult offspring., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: Psychological stressors have been related to tumor progression through the activation of beta-adrenergic receptors (β-AR) in several types of cancer., Purpose: This study aimed to investigate the expressions of β 1 - and β 2 -AR and their association with psychological and clinicopathological variables in patients with oral squamous cell carcinoma., Methods: Tumor samples from 99 patients diagnosed with OSCC were subjected to immunohistochemical reaction to detect the expression of β 1 -AR and β 2 -AR. Anxiety and depression symptoms were assessed using the Beck Anxiety Inventory and Beck Depression Inventory (BDI), respectively. The Brunel Mood Scale was used for measuring affective mood states., Results: Univariate analyzes revealed that higher expression of β 1 -AR was associated with increased alcohol consumption (p = 0.032), higher education (p = 0.042), worse sleep quality (p = 0.044) and increased levels of pain related to the primary tumor (p < 0.001). Higher expression of β 2 -AR was related with regional metastasis (p = 0.014), increased levels of pain related to the primary tumor (p = 0.044), anxiety (p < 0.001) and depressive (p = 0.010) symptoms and higher mood scores of angry (p = 0.010) and fatigue (p = 0.010). Multivariate analysis identified that patients with advanced clinical stage had lower β 1 -AR expression (OR=0.145, 95% CI=0.025-0.828, p = 0.003). Higher anxiety symptoms and higher mood fatigue are independent factors for increased β 2 -AR expression (OR=4256, 95% CI=1439-12606, p = 0.009; OR=3816, 95% CI=1258-11,573, p = 0.018, respectively)., Conclusion: This study reveal that anxiety, fatigue symptoms, and clinical staging are associated with tumor expression of beta-adrenergic receptors in patients with oral cancer., Competing Interests: Declaration of Competing Interest The authors declare that they have no conflict of interest., (Copyright © 2024.

Study Objective: There are large differences in health care among countries. A higher perioperative mortality rate (POMR) in neonates than in older children and adults has been recognized worldwide. The aim of this study was to provide a systematic review of published 24-h and 30-day POMRs in neonates from 2011 to 2022 in countries with different Human Development Index (HDI) levels., Design and Setting: A systematic review with a meta-analysis of studies that reported 24-h and 30-day POMRs in neonates was performed. We searched the databases from January 2011 to July 30, 2022., Measurements: The POMRs (per 10,000 procedures under anesthesia) were analyzed according to country HDI. The HDI levels ranged from 0 to 1, representing the lowest and highest levels, respectively (very-high-HDI: ≥ 0.800, high-HDI: 0.700-0.799, medium-HDI: 0.550-0.699, and low-HDI: < 0.550). The magnitude of the POMRs by country HDI was studied using meta-analysis., Main Results: Eighteen studies from 45 countries were included. The 24-h (n = 96 deaths) and 30-day (n = 459 deaths) POMRs were analyzed from 33,729 anesthetic procedures. The odds ratios (ORs) of the 24-h POMR in low-HDI countries were higher than those in very-high- (OR 8.4, 95% CI 1.7-40.4; p = 0.008), high- (OR 7.3, 95% CI 2.2-24.4; p = 0.001) and medium-HDI countries (OR 7.7, 95% CI 3.1-18.7; p < 0.0001) but with no odds differences between very-high- and high-HDI countries (p = 0.879), very-high- and medium-HDI countries (p = 0.915) and high- and medium-HDI countries (p = 0.689). The odds of a 30-day POMR in low-HDI countries were higher than those in very-high-HDI countries (OR 6.9, 95% CI 1.9-24.6; p = 0.002) but not in high-HDI countries (OR 1.4, 95% CI 0.6-3.0; p = 0.396)., Conclusions: The review demonstrated very high global POMRs in a surgical population of neonates independent of the country HDI level. We identified differences in 24-h and 30-day POMRs between low-HDI countries and other countries with higher HDI levels., Competing Interests: Declaration of competing interest Leandro G.

Aim: To investigate the transgenerational effect of maternal hyperglycemia on oxidative stress markers, lipid profile, glycemia, pancreatic beta (β)-cells, and reproductive outcomes in the F2 adult generation. Additionally, to expand the knowledge on transgenerational diabetes the F3 generation at birth will be evaluated., Methods: On day 5 of postnatal life female Sprague-Dawley rat newborns (F0 generation) were distributed into two groups: Diabetic (Streptozotocin-STZ, 70 mg/kg body weight, subcutaneous route) and Control rats. Adult female rats from the F0 generation and subsequently the F1 generation were mated to obtain the F2 generation, which was distributed into F2 generation (granddaughters) from control (F2&#95;C) and diabetic (F2&#95;D) rats. Oral Glucose Tolerance Test (OGTT), the area under the curve (AUC), blood biochemical analyses, and pancreatic morphology were analyzed before pregnancy. Reproductive outcomes were performed at the end of pregnancy. At birth, the glycemia and body weight of F3&#95;C and F3&#95;D rats were determined. p < 0.05 was considered significant., Results: F2&#95;D had higher body weight, triglyceride levels, and percentage of insulin-immunostained cells, contributing to glucose intolerance, and insulin resistance before pregnancy. At day 21 of pregnancy, the F2&#95;D showed increased embryonic losses before and after implantation (84.33 and 83.74 %, respectively). At birth, F3&#95;D presented hyperglycemia, and 16.3 % of newborns were large for pregnancy age (LGA)., Conclusion: Diabetes induction since the neonatal period in the first generation (F0) led to transgenerational (F2 and F3 generations) changes via the maternal lineage of female rats, confirming the relevance of control strictly the glycemia all the time., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.

Objectives: This study aimed to assess the incidence of late-onset sepsis (LOS), associated risk factors, and short-term prognosis in very low birth weight (VLBW) infants in a 10-year period., Study Design: A cohort study was conducted with 752 VLBW preterm infants-23 to 33 gestational weeks and 400 to 1,500 g birth weight-admitted to a neonatal intensive care unit from 2008 to 2017 and who survived over 72 hours. LOS was defined as clinical and laboratory signs of infection, whether or not confirmed by blood culture. VLBW infants were divided into groups and compared: no LOS versus proven LOS versus clinical LOS. Study variables included maternal, birth, and neonatal data, morbidities, procedures, etiological agents, and outcome-death, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage, and retinopathy of prematurity (ROP). Analysis of variance with multiple Tukey's or Wald's comparison with gamma distribution, and stepwise multiple logistic regression model, adjusted for year, and gestational age, were used for statistical analysis., Results: LOS incidence was 39% (proven LOS: 29%; clinical LOS: 10%). Septic VLBW infants showed higher mortality (proven LOS: 23.2%; clinical LOS: 41.9%) compared with no LOS (8.9%). Coagulase-negative staphylococci (56%), Gram-negative (26%), and fungi (8%) were the most frequent etiological agents. In comparing the groups, septic VLBW infants had lower gestational age and birth weight, presented more morbidities, and underwent more invasive procedures. The risk factors for proven and clinical LOS were days of mechanical ventilation and parenteral nutrition. LOS was associated with increased risk of death, BPD, and ROP., Conclusion: LOS showed high incidence and mortality, often caused by Gram-positive bacteria. Care interventions were the main risk factors associated. LOS had a major negative impact on short-term prognosis in VLBW infants. LOS reduction strategies are necessary and urgent., Key Points: · LOS is associated with clinically significant neonatal morbidities and death in VLBW premature infants.. · There is association between LOS and duration of intensive care interventions.. · Quality improvement initiatives can be a pathway for LOS reduction.., Competing Interests: None declared., (Thieme.

Objective: It is not clear whether response to initial treatment in papillary thyroid carcinoma (PTC) patients is best evaluated by measuring thyroglobulin (Tg) in the presence of levothyroxine (BTg) or when stimulated by elevated TSH (STg). The aim of this study was to evaluate whether response to therapy 1 year after initial treatment changes with the use of STg in relation to BTg in PTC patients treated with total thyroidectomy (TT) and radioiodine ( 131 I), and, if observed, to assess which response is better associated with clinical course., Subjects and Methods: This is a retrospective study of 148 PTC patients submitted to TT and 131 I. We analyzed the response to therapy (excellent, biochemical incomplete, or indeterminate) at 1 year after initial treatment, using BTg or STg, and compared which method was better associated with "excellent response at final evaluation.", Results: Twenty-eight patients (20.4%) presented change in response to therapy, with 17 of these (60.7%) presenting a worse response. Response using STg was 1.6 times better associated with proposed outcome [odds ratio (OR) = 4.61; confidence interval 95% (IC95%): 2.13-9.98] than with BTg (OR = 2.84; IC95%: 1.33-6.06)., Conclusion: Response to therapy at 1 year using STg was altered in approximately 20% of cases and therefore proved to be a better predictor of excellent response in the last evaluation., (© 2023.

Staphylococcus capitis has been recognized as a relevant opportunistic pathogen, particularly its persistence in neonatal ICUs around the world. Therefore, the aim of this study was to describe the epidemiological profile of clinical isolates of S. capitis and to characterize the factors involved in the persistence and pathogenesis of these strains isolated from blood cultures collected in a hospital in the interior of the state of São Paulo, Brazil. A total of 141 S. capitis strains were submitted to detection of the mecA gene and S CCmec typing by multiplex PCR. Genes involved in biofilm production and genes encoding enterotoxins and hemolysins were detected by conventional PCR. Biofilm formation was evaluated by the polystyrene plate adherence test and phenotypic resistance was investigated by the disk diffusion method. Finally, pulsed-field gel electrophoresis (PFGE) was used to analyze the clonal relationship between isolates. The mecA gene was detected in 99 (70.2%) isolates, with this percentage reaching 100% in the neonatal ICU. SCC mec type III was the most prevalent type, detected in 31 (31.3%) isolates and co-occurrence of SCC mec was also observed. In vitro biofilm formation was detected in 46 (32.6%) isolates but was not correlated with the presence of the ica operon genes. Furthermore, biofilm production in ICU isolates was favored by hyperosmotic conditions, which are common in ICUs because of the frequent parenteral nutrition. Analysis of the clonal relationship between the isolates investigated in the present study confirms a homogeneous profile of S. capitis and the persistence of clones that are prevalent in the neonatal ICU and disseminated across the hospital. This study highlights the adaptation of isolates to specific hospital environments and their high clonality.

Introduction: The effect of gestational age and fetal growth on the oxidant/antioxidant status of breast milk is poorly understood., Objective: To evaluate the oxidative stress biomarkers in colostrum and mature milk according to gestational age and fetal growth., Method: A longitudinal study with mothers of premature and term infants, born in a tertiary referral hospital between 2014-2018. Inclusion criteria: postpartum women with a singleton pregnancy, who intended to exclusively breastfeed. Exclusion criteria: maternal diabetes, use of medication, drug addiction, congenital infection or malformation, mastitis, and failure to collect colostrum. Four groups were formed according to gestational age and birth weight (appropriate and small): Preterm small ( n  = 37), Preterm appropriate ( n  = 99), Full-term small ( n  = 65), and Full-term appropriate (control, n  = 69). The colostrum samples were collected between 24-72 h and the mature milk was sampled in the 4th week of lactation for malondialdehyde (biomarker for lipid peroxidation) and Glutathione peroxidase, Catalase, and Superoxide dismutase measurements. The data were compared among groups using the Chi-square test or Fisher's exact test, one-way analysis of variance followed by Wald's Distribution test and repeated measures analysis of variance., Results: We found a lower malondialdehyde level in colostrum in preterm groups and term small for gestational age, and the antioxidant enzymes Superoxide dismutase and Catalase activities were higher for preterm compared to term groups. The malondialdehyde levels differed in mature milk samples (Full-term small > Full-term appropriate > Preterm small > Preterm appropriate). The malondialdehyde levels increased during lactation in all groups except Preterm appropriate, and the levels of Catalase decreased in preterm groups., Conclusion: The oxidative status in breast milk is influenced by gestational age and fetal growth, which increased antioxidant defense for preterm infants and decreased oxidative stimuli for small for gestational age infants. These findings contribute to encouraging breastfeeding for newborns.

Background: Neonates and infants have a higher perioperative risk of cardiac arrest and mortality than adults. The Human Development Index (HDI) ranges from 0 to 1, representing the lowest and highest levels of development, respectively. The relation between anaesthesia safety and country HDI has been described previously. We examined the relationship among the anaesthesia-related cardiac arrest rate (ARCAR), country HDI, and time in a mixed paediatric patient population., Methods: Electronic databases were searched up to July 2022 for studies reporting 24-h postoperative ARCARs in children. ARCARs (per 10,000 anaesthetic procedures) were analysed in low-HDI (HDI<0.8) vs high-HDI countries (HDI≥0.8) and over time (pre-2001 vs 2001-22). The magnitude of these associations was studied using systematic review methods with meta-regression analysis and meta-analysis., Results: We included 38 studies with 5,493,489 anaesthetic procedures and 1001 anaesthesia-related cardiac arrests. ARCARs were inversely correlated with country HDI (P<0.0001) but were not correlated with time (P=0.82). ARCARs did not change between the periods in either high-HDI or low-HDI countries (P=0.71 and P=0.62, respectively), but were higher in low-HDI countries than in high-HDI countries (9.6 vs 2.0; P<0.0001) in 2001-22. ARCARs were higher in children aged <1 yr than in those ≥1 yr in high-HDI (10.69 vs 1.48; odds ratio [OR] 8.03, 95% confidence interval [CI] 5.96-10.81; P<0.0001) and low-HDI countries (36.02 vs 2.86; OR 7.32, 95% CI 3.48-15.39; P<0.0001) in 2001-22., Conclusions: The high and alarming anaesthesia-related cardiac arrest rates among children younger than 1 yr of age in high-HDI and low-HDI countries, respectively, reflect an ongoing challenge for anaesthesiologists., Systematic Review Protocol: PROSPERO CRD42021229919., (Copyright © 2023 British Journal of Anaesthesia.

We analyzed the influence of maternal hyperglycemia and the post-weaning consumption of a high-fat diet on the mitochondrial function and ovarian development of the adult pups of diabetic rats. Female rats received citrate buffer (Control-C) or Streptozotocin (for diabetes induction-D) on postnatal day 5. These adult rats were mated to obtain female pups (O) from control dams (OC) or from diabetic dams (OD), and they received a standard diet (SD) or high-fat diet (HFD) from weaning to adulthood and were distributed into OC/SD, OC/HFD, OD/SD, and OD/HFD. In adulthood, the OGTT and AUC were performed. These rats were anesthetized and euthanized for sample collection. A high percentage of diabetic rats were found to be in the OD/HFD group (OD/HFD 40% vs. OC/SD 0% p < 0.05). Progesterone concentrations were lower in the experimental groups (OC/HFD 0.40 ± 0.04; OD/SD 0.30 ± 0.03; OD/HFD 0.24 ± 0.04 vs. OC/SD 0.45 ± 0.03 p < 0.0001). There was a lower expression of MFF (OD/SD 0.34 ± 0.33; OD/HFD 0.29 ± 0.2 vs. OC/SD 1.0 ± 0.41 p = 0.0015) and MFN2 in the OD/SD and OD/HFD groups (OD/SD 0.41 ± 0.21; OD/HFD 0.77 ± 0.18 vs. OC/SD 1.0 ± 0.45 p = 0.0037). The number of follicles was lower in the OD/SD and OD/HFD groups. A lower staining intensity for SOD and Catalase and higher staining intensity for MDA were found in ovarian cells in the OC/HFD, OD/SD, and OD/HFD groups. Fetal programming was responsible for mitochondrial dysfunction, ovarian reserve loss, and oxidative stress; the association of maternal diabetes with an HFD was responsible for the higher occurrence of diabetes in female adult pups.

Diabetes mellitus increases the risk of obstetric complications, morbidity, and infant mortality. Controlled nutritional therapy with micronutrients has been employed. However, the effect of calcium (Ca 2+ ) supplementation on diabetic pregnancy is unclear. We aimed to evaluate whether diabetic rats supplemented with Ca 2+ during pregnancy present better glucose tolerance, redox status, embryonic and fetal development, newborn weight, and the prooxidant and antioxidant balance of male and female pups. For this, newborn rats received the beta-cytotoxic drug streptozotocin for inducing diabetes on the day of birth. In adulthood, these rats were mated and treated with Ca 2+ twice a day from day 0 to day 20 of pregnancy. On day 17, the pregnant rats were submitted to the oral glucose tolerance test (OGTT). At the end of pregnancy, they were anesthetized and killed to collect blood and pancreas samples. The uterine horns were exposed for an evaluation of maternal reproductive outcomes and embryofetal development, and the offspring's liver samples were collected for redox status measurement. Nondiabetic and diabetic rats supplemented with Ca 2+ showed no influence on glucose tolerance, redox status, insulin synthesis, serum calcium levels, and embryofetal losses. The reduced rate of newborns classified as adequate for gestational age (AGA) and higher rates of LGA (large) and small (LGA) newborns and higher -SH and GSH-Px antioxidant activities in female pups were observed in diabetic dams, regardless of supplementation. Thus, maternal supplementation caused no improvement in glucose tolerance, oxidative stress biomarkers, embryofetal growth and development, and antioxidants in pups from diabetic mothers., (© 2023.

We used uncontrolled maternal diabetes as a model to provoke fetal growth restriction in the female in the first generation (F 1 ) and to evaluate reproductive outcomes and the possible changes in metabolic systems during pregnancy, as well as the repercussions at birth in the second generation (F 2 ). For this, nondiabetic and streptozotocin-induced severely diabetic Sprague-Dawley rats were mated to obtain female pups (F 1 ), which were classified as adequate (AGA) or small (SGA) for gestational weight. Afterward, we composed two groups: F 1 AGA from nondiabetic dams (Control) and F 1 SGA from severely diabetic dams (Restricted) (n minimum = 10 animals/groups). At adulthood, these rats were submitted to the oral glucose tolerance test, mated, and at day 17 of pregnancy, blood samples were collected to determine glucose and insulin levels for assessment of insulin resistance. At the end of the pregnancy, the blood and liver samples were collected to evaluate redox status markers, and reproductive, fetal, and placental outcomes were analyzed. Maternal diabetes was responsible for increased SGA rates and a lower percentage of AGA fetuses (F 1 generation). The restricted female pups from severely diabetic dams presented rapid neonatal catch-up growth, glucose intolerance, and insulin resistance status before and during pregnancy. At term pregnancy of F 1 generation, oxidative stress status was observed in the maternal liver and blood samples. In addition, their offspring (F 2 generation) had lower fetal weight and placental efficiency, regardless of gender, which caused fetal growth restriction and confirmed the fetal programming influence., (© 2023.

Objective:  The lack of data on the impact of hyperglycemia and obesity on the prevalence of pregnancy-specific urinary incontinence (PSUI) led us to conduct a cross-sectional study on the prevalence and characteristics of PSUI using validated questionnaires and clinical data., Methods:  This cross-sectional study included 539 women with a gestational age of 34 weeks who visited a tertiary university hospital between 2015 and 2018. The main outcome measures were the prevalence of PSUI, the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF), and the Incontinence Severity Index (ISI) questionnaires. The women were classified into four groups: normoglycemic lean, normoglycemic obese, hyperglycemic lean, and hyperglycemic obese. The differences between groups were tested using descriptive statistics. Associations were estimated using logistic regression analysis and presented as unadjusted and adjusted odds ratios., Results:  Prevalence rates of PSUI were no different between groups. However, significant difference in hyperglycemic groups worse scores for severe and very severe PSUI. When adjusted data for confound factors was compared with normoglycemic lean group, the hyperglycemic obese group had significantly higher odds for severe and very severe forms of UI using ICIQ-SF (aOR 3.157; 95% CI 1.308 to 7.263) and ISI (aOR 20.324; 95% CI 2.265 to 182.329) questionnaires and highest perceived impact of PSUI (aOR 4.449; 95% CI 1.591 to 12.442)., Conclusion:  Our data indicate that obesity and hyperglycemia during pregnancy significantly increase the odds of severe forms and perceived impact of PSUI. Therefore, further effective preventive and curative treatments are greatly needed., Competing Interests: The authors have no conflicts of interest to declare., (Federação Brasileira de Ginecologia e Obstetrícia.

Studies on vitamin D supplementation have been performed in experimental and clinical investigations considering gestational diabetes and/or vitamin D deficiency in pregnancy. However, the results are controversial and few present the effects and mechanisms of this micronutrient on pregestational diabetes. The objective of this study was to evaluate the effect of vitamin D on the pregnancy of rats with pre-existing diabetes and their fetuses. Pregestational diabetes was induced in Sprague-Dawley rats at birth. The adult diabetic and nondiabetic rats were orally administered with vitamin D (cholecalciferol) throughout the pregnancy. The diabetes status was monitored during pregnancy by an oral glucose tolerance test (OGTT). At the end of the pregnancy, pancreas and blood samples were collected for morphological analyses and lipid peroxidation measurements, respectively. The influence of vitamin D treatment on reproductive outcomes, fetal growth, and development were compared to those of untreated diabetic and nondiabetic pregnant rats. P < 0.05 was considered a significant statistical limit. The diabetic rats given vitamin D had a greater number of insulin-positive cells, contributing to reduced blood glucose levels and thiobarbituric acid reactive substance concentrations (TBARS-an indicator of membrane lipid peroxidation), and increased reduced thiol group levels, contributing to suitable intrauterine conditions for better fetal development, which was confirmed by higher fetal viability rates. Thus, this study shows the effects and mechanisms of vitamin D supplementation on pre-existing diabetes in pregnant rats, confirming its beneficial effects on maternal redox status and glycemic control, and the decline of adverse maternal-fetal repercussions., (© 2022.

Aims: To evaluate the morphological changes in the pancreatic islet cells of adult female pups born to diabetic rats and fed a high-fat diet., Main Methods: Female Sprague-Dawley rats were distributed into four experimental groups (n = 10 animals/group): 1) female pups from non-diabetic dams and fed a standard diet (OC/SD), 2) female pups from non-diabetic dams and fed a high-fat (OC/HFD), 3) female pups from diabetic dams and fed a standard diet (OD/SD) and 4) female pups from diabetic dams and fed a high-fat diet (OD/HFD). In adulthood, the rats were submitted to the oral glucose tolerance test and later euthanized to collect the pancreas for the analysis of pancreatic islets., Key Findings: The OC/HFD and OD/SD groups showed an increased percentage of cells immunostained for insulin and a decreased percentage and intensity of staining for somatostatin. The OD/HFD group showed an increased percentage of cells immunostained for insulin and glucagon and a higher staining intensity for glucagon. There was a progressive increase in blood glucose in the OC/HFD, OD/SD, and OD/HFD groups., Significance: The association between maternal diabetes and/or the administration of high-fat diet-induced changes in the pancreatic hormonal triad of female pups in adulthood. In turn, these changes in the pancreatic islets are not capable of causing decreased blood glucose in the offspring, contributing to the development of glucose intolerance in adulthood., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interest., (Copyright © 2022 Elsevier Inc.

Objectives: to analyze the association between nursing workload and neonatal mortality risk in newborns admitted to the Neonatal Intensive Care Unit., Methods: this is an observational, cross-sectional study conducted from January 2019 to January 2020., Results: the sample consisted of 399 newborns, 55.4% male, Nursing Activities Score mean of 67.5%, and Score for Neonatal Acute Physiology Perinatal Extension mean of 17.7, revealed itself as a predictor of the risk of death, while gestational age, length of hospitalization, and the first-minute Apgar established a protective relationship. The correlation between workload and neonatal mortality was low (r= 0.23, p=0.0009)., Conclusions: the workload of the nursing team is not associated with the risk of mortality in the Neonatal Intensive Care Unit, as measured by the Nursing Activities Score.

Clinical and epidemiological studies show that maternal hyperglycemia can change the programming of offspring leading to transgenerational effects. These changes may be related to environmental factors, such as high-fat diet (HFD) consumption, and contribute to the comorbidity onset at the adulthood of the offspring. The objective of this study was to evaluate the hyperglycemic intrauterine environment, associated or not with an HFD administered from weaning to adult life on the periovarian adipose tissue of rat offspring Maternal diabetes was chemically induced by Streptozotocin. Female offsprings were randomly distributed into four experimental groups (n = 5 animals/group): Female offspring from control or diabetic mothers and fed an HFD or standard diet. HFD was prepared with lard enrichment and given from weaning to adulthood. On day 120 of life, the rats were anesthetized and sacrificed to obtain adipose tissue samples. Then, the hyperglycemic intrauterine environment and HFD fed after weaning caused a higher body weight, total fat, and periovarian fat in adult offspring, which could compromise the future reproductive function of these females. These rats showed higher adiposity index and adipocyte area, contributing to hypertrophied adipose tissue. Therefore, maternal diabetes itself causes intergenerational changes and, in association with the HFD consumption after weaning, exacerbated the changes in the adipose tissue of adult female offspring.

Maternal diabetes-mediated fetal programming is widely discussed, however, it is important to define the extent to which intrauterine hyperglycemia interferes with the health of female pups, along with determining whether these changes can be perpetuated across generations. This study aimed to evaluate the effects of maternal diabetes on fetal programming and the repercussions on the metabolism of pregnant and nonpregnant female pups. Diabetes status was induced (diabetic group-D) using streptozotocin (a beta cell cytotoxic drug) on the fifth postnatal day of female rats, while controls received a citrate buffer (Control-C). In adulthood, the rats were mated to obtain their female pups. At 90 days of age, half of the female pups were mated (preg) and the other half continued virgin (Npreg). Furthermore, they were distributed into four groups: OC/Npreg and OC/preg-female pups from control mothers; OD/Npreg and OD/preg-female pups from diabetic mothers. At 115 days of life and/or 17 days of pregnancy, the oral glucose tolerance test (OGTT) was performed with blood collection for insulin measurement. At 120 days of life and/or 21 days of pregnancy, the rats were anesthetized and euthanized to determine their blood oxidative stress status. The OD/Npreg group showed glucose intolerance during OGTT ( p  < 0.0001), while the OD/preg group showed increased insulin secretion during OGTT ( p  < 0.0001) and insulin resistance (IR; p  = 0.0027). An increase in homeostatic model assessment β was shown in the pregnant groups, regardless of maternal diabetes ( p  < 0.0001). The OD/preg group presented increased thiobarbituric acid reactive substances ( p  < 0.0001) and -SH levels ( p  = 0.0005) and decreased superoxide dismutase activity ( p  = 0.0063). Additionally, small fetuses for gestational age ( p  < 0.0001) were found in these rats. In conclusion, exposure to maternal hyperglycemia compromises the glycemic metabolism of female pups before and during pregnancy and causes oxidative stress, IR, and impaired fetal growth during pregnancy.

Objective: The provision of adequate enteral nutrition to preterm infants is a great challenge, and preeclampsia (PE) may have a detrimental effect on the safety of nutrition supply. This study aims to investigate the influence of early-onset PE on preterm infants' enteral feeding tolerance and growth during hospitalization., Methods: This is a prospective study with 55 preterm infants <34 weeks born to PE mothers matched by gestational age with 55 preterm infants born to normotensive mothers from 2013 to 2016. We evaluated maternal, gestational, and neonatal clinical data. The outcomes were feeding intolerance and growth during hospitalization. Comparison between groups was performed by Student's t-test or Mann-Whitney U test, chi-square test, or Fisher's exact test. Multiple logistic regression was used to investigate whether PE was an independent risk factor for feeding intolerance., Results: The mean gestational age was 30 weeks. Preterm infants of mothers with PE had lower birth weight and were smaller at discharge. Feeding intolerance was frequent, but necrotizing enterocolitis was rare in this sample (PE=4% vs. control=2%) with no difference between groups. Preterm infants of mothers with PE had worse growth outcomes; however, PE was not an independent risk factor for feeding intolerance. The increase in gestational age was a protective factor, and being born small for gestational age (SGA) increased the risk of feeding intolerance by six times., Conclusions: Preterm infants of mothers with early-onset PE were more likely to be born SGA and had a worse growth trajectory during hospitalization. In adjusted analyses, however, low gestational age and SGA were independent predictors of feeding intolerance.

Maternal diabetes-induced fetal programming predisposes offspring to type 2 diabetes, cardiovascular disease, and obesity in adulthood. However, lifelong health and disease trajectories depend on several factors and nutrition is one of the main ones. We intend to understand the role of maternal diabetes-induced fetal programming and its association with a high-fat diet during lifelong in the female F1 generation focusing on reproductive outcomes and the possible changes in physiological systems during pregnancy as well as the repercussions on the F2 generation at birth. For this, we composed four groups: F1 female pups from control (OC) or from diabetic dams (OD) and fed with standard (SD) or high-fat diet from weaning to full-term pregnancy. During pregnancy, glucose intolerance and insulin sensitivity were evaluated. In a full-term pregnancy, the maternal blood and liver were collected to evaluate redox status markers. The maternal blood, placental tissue, and fetal blood (pool) were collected to evaluate adiponectin and leptin levels. Maternal reproductive parameters were evaluated as well. Maternal diabetes and high-fat diet consumption, in isolation, were both responsible for increased infertility rates and fasting glucose levels in the F1 generation and fetal growth restriction in the F2 generation. The association of both conditions showed, in addition to those, increased lipoperoxidation in maternal erythrocytes, regardless of the increased endogenous antioxidant enzyme activities, glucose intolerance, decreased number of implantation sites and live fetuses, decreased litter, fetal and placental weight, increased preimplantation losses, and increased fetal leptin serum levels. Thus, our findings show that fetal programming caused by maternal diabetes or lifelong high-fat diet consumption leads to similar repercussions in pregnant rats. In addition, the association of both conditions was responsible for glucose intolerance and oxidative stress in the first generation and increased fetal leptin levels in the second generation. Thus, our findings show both the F1 and F2 generations harmed health after maternal hyperglycemic intrauterine environment and exposure to a high-fat diet from weaning until the end of pregnancy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Sinzato, Paula, Gallego, Moraes-Souza, Corrente, Volpato and Damasceno.)

Objectives: To describe the trend of physical activity (PhA) in four domains performed by pregnant women living in Brazilian capitals and the Federal District (FD) and to verify the association between sociodemographic factors and the practice of leisure-time physical activity between 2007 and 2017., Methods: Time trend study carried out with data from the Surveillance System of Risk Factors for chronic diseases by telephone survey (Vigitel). A total of 3,730 pregnant women were interviewed in the period, considering sociodemographic variables (age, macro-region, work, marital status, schooling, skin color) and physical activity in the four domains (leisure-time, work, commuting, domestic - yes/no). For pregnant women who performed leisure-time physical activity, its duration was inquired, expressed in the variable PhA ≥ 150 minutes/week (yes/no). The time trend was evaluated by variance-weighted linear regression (average annual variation was expressed in percentage points - pp) and the association of sociodemographic factors with leisure-time physical activity by Poisson regression, with prevalence ratio (PR) estimation., Results: The prevalence of pregnant women with 12 years of schooling or more increased in the analyzed period (+1.37 pp/year), as well as the prevalence of pregnant women with more than 35 years of age (+1.11 pp/year) and those who work (+0.75 pp/year). The prevalence of leisure-time physical activity by pregnant women increased from 29.3% in 2007 to 37.6% in 2017 (+1.37 pp/year), and of PhA ≥ 150min/week from 2.3% to 20.6% (+2.33 pp/year), respectively, and there was a reduction in domestic physical activities from 63.9% to 38.9% (-1.65 pp/year). The prevalence of leisure-time physical activity was higher among pregnant women with more than 12 years of schooling (PR = 2.22; 95%CI: 1.73-2.84) as compared to those with less than 8 years of age, and lower among black/brown/indigenous pregnant women, compared to white/yellow ones (PR = 0.87; 95%CI: 0.78-0.97). The prevalence of PhA ≥ 150min/week increased according to years of schooling and age., Conclusions: The prevalence of leisure-time physical activity and its performance for ≥ 150 minutes/week increased in the analyzed period, and both were directly associated with greater schooling.

Background: Stroke is one of the leading causes of death and neurological disability in the world. Several scales help professionals in the early recognition of the disease. However, none of these were developed in Brazil., Objectives: To translate the Los Angeles Prehospital Stroke Screen (LAPSS) into Brazilian Portuguese, and cross-culturally adapt and validate the scale in a representative sample of the Brazilian population., Methods: This study was carried out in two phases: the first consisted in the translation and cross-cultural validation of the LAPSS, and the second in a cross-sectional study with prospectively collected data in patients with suspected stroke treated in a Brazilian prehospital and referred to a stroke center. Statistical analysis was used to assess the sensitivity, specificity, and accuracy of the scale. Cohen's Kappa coefficient (κ) was used for psychometric assessment., Results: After translation and cross-cultural adaptation, the scale was applied to 86 patients. The scale presented a sensitivity of 83.8%, positive predictive value of 79.50%, specificity of 40.70%, negative predictive value of 47.80%, and accuracy of 77%. Cohen's kappa coefficient was calculated using data from 26 (30.23%) patients and the results showed excellent inter-rater reliability in the majority of the items (52.96%)., Conclusions: The scale was translated and cross-culturally adapted for use in Brazil. The scale presented high sensitivity and accuracy but low specificity, and the Cohen's kappa demonstrated inter-rater reliability. The greatest difficulties occurred when the evaluation included subjective identifications. The scale excluded patients < 45 years old as stroke suspects.

We evaluated the influence of the hyperglycemic intrauterine environment and postweaning consumption of a high-fat diet (HFD) on the glycemia, insulin, lipid, and immunological profile of rat offspring in adulthood. Female rats received citrate buffer (Control-C) or Streptozotocin (a beta cell-cytotoxic drug to induce diabetes-D) on postnatal day 5. In adulthood, these rats were mated to obtain female offspring, who were fed a standard diet (SD) or HFD from weaning to adulthood (n = 10 rats/group). OC/SD and OC/HFD represent female offspring of control mothers and received SD or HFD, respectively; OD/SD and OD/HFD represent female offspring of diabetic mothers and received SD or HFD, respectively. At adulthood, the oral glucose tolerance test (OGTT) was performed and, next, the rats were anesthetized and euthanized. Pancreas was collected and analyzed, and adipose tissue was weighted. Blood samples were collected to determine biochemical and immunological profiles. The food intake was lower in HFD-fed rats and visceral fat weight was increased in the OD/HFD group. OC/HFD, OD/SD, and OD/HFD groups presented glucose intolerance and lower insulin secretion during OGTT. An impaired pancreatic beta-cell function was shown in the adult offspring of diabetic rats, regardless of diet. Interleukin (IL)-6 and IL-10 concentrations were lower in the OD/HFD group and associated to a low-grade inflammatory condition. The fetal programming was responsible for impaired beta cell function in experimental animals. The association of maternal diabetes and postweaning HFD are responsible for greater glucose intolerance, impaired insulin secretion and immunological change., (© The Author(s) 2021.

Cancer patients may have a dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and abnormal secretion of cortisol. Increased cortisol levels have been associated with worse prognosis in patients with different types of tumors. Although anxiety and depression can trigger an abnormal cortisol secretion, little is known regarding the influence of these emotional disorders on HPA axis dysregulation in cancer patients when evaluating together with demographic, clinicopathological and biobehavioral variables. This cross-sectional study analyzed the pre-treatment plasma cortisol levels of 133 patients with oral squamous cell carcinoma (OSCC) and its association with demographic, clinicopathological, biobehavioral and psychological variables. Plasma cortisol levels were measured by electrochemiluminescence, and anxiety and depression symptoms were assessed using Beck Anxiety Inventory (BAI) and Depression (BDI), respectively. Demographic, clinicopathological and biobehavioral data were collected from patients' medical records. Results from multivariate analysis showed that the occurrence of cancer-induced pain was predictive for higher cortisol levels (OR = 5.388, p = 0.003). Men with OSCC were 4.5 times more likely to have higher plasma cortisol levels than women (OR = 4.472, p = 0.018). The effect of sex on cortisol concentrations was lost in the adjusted model for clinical staging (OR = 2.945, p = 0.116). The absence of chronic alcohol consumption history was a protective factor for highest hormone concentrations in oral cancer patients (OR = 0.104, p = 0.004). Anxiety symptoms measured by BAI as "hands trembling" (OR = 0.192, p = 0.016) and being "nervous" (OR = 0.207, p = 0.0004) were associated with lower cortisol levels. In contrast, the feeling of "fear of losing control" was a risk factor for highest hormone concentrations (OR = 6.508, p = 0.0004). The global score and specific symptoms of depression measured by the BDI were not predictive for plasma hormone levels (p > 0.05). Together, our results show that pain, alcohol consumption and feeling fear are independent factors for increased systemic cortisol levels in patients with oral cancer. Therefore, psychological intervention, as well as control of pain and alcohol consumption, should be considered to prevent the negative effects of cortisol secretion dysregulation in cancer patients., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

Background: Despite the benefits in improving the clinical state of people living with HIV/aids (PLWHA), some side effects associated with the use of antiretroviral therapy (ART) are reported. Redistribution of body fat has been associated with treatment and is characterized by morphological changes, also known as lipodystrophy. The complications of metabolic and morphological changes in these individuals seem to increase the risk of cardiovascular disease. Adipocytokines are proteins that have essential functions in biological processes, in which the levels of these proteins are related to the pathogenesis of metabolic syndrome (MS) and cardiovascular disease. Recent studies have shown that such levels are generally modified in PLWHA, regardless of whether the treatment is established or not. An application of methods for body fat estimation in patients with fat redistribution, as in the case of aids, especially those that quantify body fat by segments, appears to clarify these alterations and plays an important role in the development of multiprofessional treatment. Objectives: This investigation was carried out to compare and correlate body composition, biochemical metabolic parameters, and levels of adipocytokines and cytokines of PLWHA, with and without lipodystrophy, with individuals with negative HIV serology and stratified by sex. Material and Methods: This is a cross-sectional study in which body composition, metabolic and anthropometric changes, and levels of adipocytokines of 110 individuals were assessed. These individuals were paired in sex, age, and body mass index (BMI) and subdivided into three groups: PLWHA with and without a clinical diagnosis of lipodystrophy associated with HIV, and a group control. Results: Collinearity was identified both in the general sample and for genders of the waist-to-height ratio (WHtR) with all anthropometric parameters, except for muscle mass. The results show strong association between IFN-γ and TNF-α both in the general sample and for genders and moderate correlation between leptin and fasting glucose for women; worsening of the triglyceride profile in both women with lipodystrophy compared with the control group and men without lipodystrophy compared with the control group; higher serum TNF-α values among men without lipodystrophy compared to those with HIV-associated lipodystrophy (HALS). Conclusions: The results of this study underline that, considering the manifestations of the syndrome, these patients have a high-risk endocrine metabolic profile for cardiovascular events., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Sacilotto, Papini, Mendes, Gatto, Pereira, Corrente and Silva.)

Objective: To evaluate whether there is a relationship between diet quality and bone health in a group of elderly Brazilian women., Methods: A cross-sectional study was performed with 105 elderly women. Participants were evaluated regarding diet quality (good, needing improvement, and poor) and its relationship with bone mineral density (BMD), bone-specific alkaline phosphatase (BSAP), and C-telopeptide (CTX)., Results: Fifty eight participants (55.2%) presented a poor-quality diet and 47 (44.8%) required dietary improvements, while no subjects presented a good quality diet. The group requiring dietary improvements had lower CTX [0.35 (0.05;1.09) vs. 0.52 (0.10;1.45); p = 0.03)] and BSAP (38.7 ± 12.9 U/L vs. 46.10 ± 15.2 U/L; p < 0.01) levels than the poor-quality diet group. Groups did not differ in terms of BMD., Conclusion: In this group of elderly Brazilian women, there was a relationship between diet quality and bone health, where worse diet quality was associated with higher levels of bone remodelling markers.

Intra-operative cardiac arrests differ from most in-hospital cardiac arrests because they reflect not only the patient's condition but also the quality of surgery and anaesthesia care provided. We assessed the relationship between intra-operative cardiac arrest rates and country Human Development Index (HDI), and the changes occurring in these rates over time. We searched PubMed, EMBASE, Scopus, LILACS, Web of Science, CINAHL and SciELO from inception to 29 January 2020. For the global population, rates of intra-operative cardiac arrest and baseline ASA physical status were extracted. Intra-operative cardiac arrest rates were analysed by time, country HDI status and ASA physical status using meta-regression analysis. Proportional meta-analysis was performed to compare intra-operative cardiac arrest rates and ASA physical status in low- vs. high-HDI countries and in two time periods. Eighty-two studies from 25 countries with more than 29 million anaesthetic procedures were included. Intra-operative cardiac arrest rates were inversely correlated with country HDI (p = 0.0001); they decreased over time only in high-HDI countries (p = 0.040) and increased with increasing ASA physical status (p < 0.0001). Baseline ASA physical status did not change in high-HDI countries (p = 0.106), while it decreased over time in low-HDI countries (p = 0.040). In high-HDI countries, intra-operative cardiac arrest rates (per 10,000 anaesthetic procedures) decreased from 9.59 (95%CI 6.59-13.16) pre-1990 to 5.17 (95%CI 4.42-5.97) in 1990-2020 (p = 0.013). During the same time periods, no improvement was observed in the intra-operative cardiac arrest rates in low-HDI countries (p = 0.498). Odds ratios of intra-operative cardiac arrest rates in ASA 3-5 patients were 8.48 (95%CI 1.67-42.99) times higher in low-HDI countries than in high-HDI countries (p = 0.0098). Intra-operative cardiac arrest rates are related to country-HDI and decreased over time only in high-HDI countries. The widening gap in these rates between low- and high-HDI countries needs to be addressed globally., (© 2021 Association of Anaesthetists.)

Recent studies report seasonality in healthcare-associated infections, especially those caused by Acinetobacter baumannii complex. We conducted an ecologic study aimed at analyzing the impact of seasons, weather parameters and climate control on the incidence and carbapenem-resistance in A. baumannii complex bloodstream infections (ABBSI) in hospitals from regions with different climates in Brazil. We studied monthly incidence rates (years 2006-2015) of ABBSI from hospitals in cities from different macro-regions in Brazil: Fortaleza (Ceará State, Northeast region), Goiânia (Goiás State, Middle-west) and Botucatu (São Paulo State, Southeast). Box-Jenkins models were fitted to assess seasonality, and the impact of weather parameters was analyzed in Poisson Regression models. Separate analyses were performed for carbapenem-resistant versus carbapenem-susceptible isolates, as well as for infections occurring in climate-controlled intensive care units (ICUs) versus non-climate-controlled wards. Seasonality was identified for ABSSI ICUs in the Hospitals from Botucatu and Goiânia. In the Botucatu hospital, where there was overall seasonality for both resistance groups, as well as for wards without climate control. In that hospital, the overall incidence was associated with higher temperature (incidence rate ratio for each Celsius degree, 1.05; 95% Confidence Interval, 1.01-1.09; P = 0.006). Weather parameters were not associated with ABBSI in the hospitals from Goiânia and Fortaleza. In conclusion, seasonality was found in the hospitals with higher ABBSI incidence and located in regions with greater thermal amplitude. Strict temperature control may be a tool for prevention of A. baumanii infections in healthcare settings., Competing Interests: The authors have declared that no competing interests exist.

Background: Preeclampsia is associated with important vascular maternal changes. However, its repercussions on newborns' circulation have hardly been reported., Objective: To investigate whether early-onset preeclampsia is associated with altered blood flow of the superior mesenteric artery (SMA) in preterm infants., Materials and Methods: Prospective study with 60 preterm infants of mothers with early-onset preeclampsia (PE) and 60 of normotensive mothers, paired according to the gestational age, from 2013 to 2016. Maternal, gestational, and neonatal clinical data were evaluated. The outcome of interest was the blood flow velocity in SMA, evaluated by the peak systolic velocity and end-diastolic velocity and by the resistance index and pulsatility index, through the Doppler ultrasound in the first 72 h of life. Covariance analysis was used to determine the PE effect on the SMA blood flow, controlling for possible confounding variables., Results: The mean gestational age was 30 weeks. Infants of mothers with PE had significantly lower values of peak systolic and end-diastolic velocity (57.75 ± 17.49 and 12.29 ± 5.74) compared with the control group (67.17 ± 29.57 and 15.03 ± 7.52), even after control of covariates., Conclusion: Early-onset preeclampsia is associated with decreased blood flow of SMA in preterm infants on the first days of life.

Introduction: Osteoporosis and metabolic syndrome (MetS) are diseases that have serious public health consequences, reducing the quality of life of patients and increasing morbidity and mortality, with substantial healthcare expenditures., Objective: To evaluate the impact of MetS on bone mineral density (BMD) and biochemical markers of bone formation and resorption in adolescents with excess weight., Method: A descriptive and analytical cross-sectional study was performed that evaluated 271 adolescents of both sexes (10 to 16 years). From the total sample, 42 adolescents with excess weight and the presence of MetS (14%) were selected. A further 42 adolescents with excess weight and without MetS were chosen, matched for chronological age, bone age, and pubertal developmental criteria to those with MetS, for each sex. Anthropometric measurements, blood pressure collection, and biochemical tests were performed in all adolescents, as well as evaluation of BMD and the bone biomarkers osteocalcin (OC), bone alkaline phosphatase (BAP), and carboxy-terminal telopeptide (S-CTx)., Results: The adolescents with excess weight and MetS exhibited significantly lower transformed BMD and concentrations of BAP, OC, and S-CTx compared to the matched group, except for OC in boys. A negative and significant correlation was observed between total body BMD and BAP (r = -0.55568; p = 0.005), OC (r = -0.81760; p = < .000), and S-CTx (r = -0.53838; p = 0.011) in girls., Conclusion: Metabolic syndrome may be associated with reduced bone mineral density and biochemical markers of bone formation and resorption in adolescents with excess weight., Competing Interests: The authors have declared that no competing interests exist.

The validity and applicability of tactile battery tests for the diagnosis and medical follow-up of patients with Alzheimer's disease and other dementia syndromes do not have their usefulness well understood in clinical practice. While haptic abilities in older individuals receive less attention, in earlier stages of human life they are well focused on. There are even fewer studies on tactile memory, including episodic memory of demented individuals with or without sensorial limitations. The applicability of a new haptic memory battery was evaluated in patients with Alzheimer's disease with mild or moderate commitment., Objective: The aim of this study is to apply a battery based on tactile perception, recognition, and recollection of everyday objects in patients with Alzheimer's disease, testing tactile delayed recall memory discrimination and late recognition to compare validated visual and verbal tests., Methods: Tactile-, visual-, and verbal-based memory performance was registered in 21 patients diagnosed with Alzheimer's disease., Results: Except for tactile identification, it showed that there was a close relationship between the three sensory modalities of memory, with an apparent better performance of tactile incidental memory and recognition compared with the test with pictures., Conclusions: The haptic evaluation of memory demonstrated applicability in the evaluation of memory dysfunction in patients with Alzheimer's disease. Further studies are needed to establish the sensibility and specificity of the proposed test that had a small sample size and many limitations., Competing Interests: Disclosure: The authors report no conflicts of interest.

Study Objective: Older patients have a higher probability of developing major complications during the perioperative period than other adult patients. Perioperative mortality depends on not only on a patient condition but also on the quality of perioperative care provided. We tested the hypothesis that the perioperative mortality rate among older patients has decreased over time and is related to a country's Human Development Index (HDI) status., Design: A systematic review with a meta-regression and meta-analysis of observational studies that reported perioperative mortality rates in patients aged ≥60 years was performed. We searched the PubMed, EMBASE, LILACS and SciELO databases from inception to December 30, 2019., Setting: Mortality rates up to the seventh postoperative day were evaluated., Measurements: We evaluated the quality of the included studies. Perioperative mortality rates were analysed by time, country HDI status and baseline American Society of Anesthesiologists (ASA) physical status using meta-regression. Perioperative mortality and ASA status were analysed in low- and high-HDI countries during two time periods using proportion meta-analysis., Main Results: We included 25 studies, which reported 4,412,100 anaesthesia procedures and 3568 perioperative deaths from 12 countries. Perioperative mortality rates in high-HDI countries decreased over time (P = 0.042). When comparing pre-1990 to 1990-2019, in high-HDI countries, the perioperative mortality rates per 10,000 anaesthesia procedures decreased 7.8-fold from 100.85 (95% CI 43.36 to 181.72) in pre-1990 to 12.98 (95% CI 6.47 to 21.70) in 1990-2019 (P < 0.0001). There were no studies from low-HDI countries pre-1990. In the period from 1990 to 2019, perioperative mortality rates did not differ between low- and high-HDI countries (P = 0.395) but the limited number of patients in low-HDI countries impaired the result. Perioperative mortality rates increased with increasing ASA status (P < 0.0001). There were more ASA III-V patients in high-HDI countries than in low-HDI countries (P < 0.0001), and the perioperative mortality rate increased 24-fold in ASA III-V patients compared with ASA I-II patients (P < 0.0001)., Conclusion: The perioperative mortality rates in older patients have declined over the past 60 years in high-DHI countries, highlighting that perioperative safety in this population is increasing in these countries. Since data prior to 1990 were lacking in low-HDI countries, the evolution of their mortality rates could not be analysed. The perioperative mortality rate was similar in low- and high-HDI countries in the post-1990 period, but the low number of patients in the low-HDI countries does not allow a definitive conclusion., (Copyright © 2020 Elsevier Inc.

Background: Use of internationally standardized instruments to assist healthcare professionals in accurately recognizing stroke early is recommended. The process of translation and cross-cultural adaptation is important for ensuring that scales are interpreted in the same way in different languages, thus ensuring applicability in several countries., Objective: To translate into Brazilian Portuguese, cross-culturally adapt and validate the Cincinnati Prehospital Stroke Scale, using a representative sample of the Brazilian population., Method: The present study included patients with suspected stroke who were treated at a Brazilian emergency medical service and referred to a stroke center. A systematic process of translation and cross-cultural adaptation of the original scale and application of the final instrument was performed. Statistical analysis was used to assess the sensitivity, specificity and accuracy of the scale. Cohen's kappa coefficient was used to assess inter-rater reliability., Results: After translation and cross-cultural adaptation, the scale was applied to 64 patients. It showed 93.0% accuracy and 92.4% sensitivity in relation to the final "gold standard" diagnosis. Cohen's kappa coefficient was calculated using data from 26 patients (40.6%) and showed excellent inter-rater reliability between items on the scale (0.8385 to 1.0000)., Conclusion: The scale demonstrated excellent accuracy, sensitivity and inter-rater reliability. It was a useful tool for assisting healthcare professionals during initial assessments on patients with suspected stroke and significantly contributed to early recognition of stroke in a simple and quick manner.

The aim was to assess the role of Metabolic Syndrome (MetS) diagnostic markers, recommended by three different guidelines, in the prediction of hyperglycemia in pregnancy. This cross-sectional cohort study included 506 non-diabetic women, with a singleton pregnancy, who underwent a diagnostic test for hyperglycemia at 24-28 weeks. Clinical, anthropometric, and laboratory data were obtained. The relationship between MetS markers and the risk of hyperglycemia was evaluated by backward stepwise logistic regression analysis (OR, 95% CI). The limit of statistical significance was 95% (p < 0.05). Triglycerides (TG) ≥ 150 mg/dL, blood pressure (BP) ≥ 130/85 mmHg, fasting glucose (FG) ≥ 100 mg/dL, and waist circumference (WC) > 88 cm were identified as independent risk factors for hyperglycemia in pregnancy. These results might help the selective screening of hyperglycemia in pregnancy.

Introduction: Studies have shown that both perioperative and anesthesia-related cardiac arrest (CA) and mortality rates are much higher in developing countries than in developed countries. This review aimed to compare the rates of perioperative and anesthesia-related CA and mortality during 2 time periods in Brazil., Methods: A systematic review with meta-analysis of full-text Brazilian observational studies was conducted by searching the Medline, EMBASE, LILACS and SciELO databases up to January 29, 2020. The primary outcomes were perioperative CA and mortality rates and the secondary outcomes included anesthesia-related CA and mortality events rates up to 48 postoperative hours., Results: Eleven studies including 719,273 anesthetic procedures, 962 perioperative CAs, 134 anesthesia-related CAs, 1,239 perioperative deaths and 29 anesthesia-related deaths were included. The event rates were evaluated in 2 time periods: pre-1990 and 1990-2020. Perioperative CA rates (per 10,000 anesthetics) decreased from 39.87 (95% confidence interval [CI]: 34.60-45.50) before 1990 to 17.61 (95% CI: 9.21-28.68) in 1990-2020 (P < 0.0001), while the perioperative mortality rate did not alter (from 19.25 [95% CI: 15.64-23.24] pre-1990 to 25.40 [95% CI: 13.01-41.86] in 1990-2020; P = 0.1984). Simultaneously, the anesthesia-related CA rate decreased from 14.39 (95% CI: 11.29-17.86) to 3.90 (95% CI: 2.93-5.01; P < 0.0001), while there was no significant difference in the anesthesia-related mortality rate (from 1.75 [95% CI: 0.76-3.11] to 0.67 [95% CI: 0.09-1.66; P = 0.5404)., Conclusions: This review demonstrates an important reduction in the perioperative CA rate over time in Brazil, with a large and consistent decrease in the anesthesia-related CA rate; however, there were no significant differences in perioperative and anesthesia-related mortality rates between the assessed time periods., Competing Interests: The authors have declared that no competing interests exist.

Introduction: Introduction: in the Brazilian population it is noted that obesity is increasing in all ages, particularly in the elderly, due to changes in habits and the consumption of foods with high energy density. The objective of this study was to reanalyze the data from a Food Frequency Questionnaire (FFQ) in order to obtain new food patterns from the elderly population. Methods: sociodemographic data, morbidities, and Food Frequency Questionnaire (FFQ) results were collected from a representative sample of 355 elderly in the city of Botucatu, São Paulo, Brazil, and stratified by Basic Health Unit in the municipality. The data from the FFQ were transformed into daily consumption, and only foods with an intake of at least 40 % were included in the analysis. Eating patterns were obtained by means of an exploratory and confirmatory factor analysis using the principal component method, associating them with obesity and demographic variables obtained via structural equation models (SEMs). Results: with the data from the FFQ, four eating patterns were obtained using the exploratory and confirmatory factor analysis: healthy, traditional, snacks and weekend meals, and mild diet. Using SEMs and considering general obesity as measured by the body mass index (BMI), being female, younger, hypertensive, diabetic, and having lower adherence to the traditional pattern increases BMI. Additionally, using SEMs and considering central obesity as measured by waist circumference (WC), being hypertensive or diabetic, and having a lower adherence to the traditional pattern increases WC. Conclusion: removing excess zeroes from FFQ data it was possible to obtain well-defined eating patterns using the exploratory and confirmatory analysis, and to associate them with obesity through SEMs.
