High concentrations of fructose cause brain damage in mice.

Excessive fructose consumption is associated with the incidence of obesity and systemic inflammation, resulting in increased oxidative damage and failure to the function of brain structures. Thus, we hypothesized that fructose consumption will significantly increase inflammation, oxidative damage, and mitochondrial dysfunction in the mouse brain and, consequently, memory damage. The effects of different fructose concentrations on inflammatory and biochemical parameters in the mouse brain were evaluated. Male Swiss mice were randomized into four groups: control, with exclusive water intake, 5%, 10%, and 20% fructose group. The 10% and 20% fructose groups showed an increase in epididymal fat, in addition to higher food consumption. Inflammatory markers were increased in epididymal fat and in some brain structures. In the evaluation of oxidative damage, it was possible to observe significant increases in the hypothalamus, prefrontal cortex, and hippocampus. In the epididymal fat and in the prefrontal cortex, there was a decrease in the activity of the mitochondrial respiratory chain complexes and an increase in the striatum. Furthermore, short memory was impaired in the 10% and 20% groups but not long memory. In conclusion, excess fructose consumption can cause fat accumulation, inflammation, oxidative damage, and mitochondrial dysfunction, which can damage brain structures and consequently memory.

Extruded urea levels in lamb supplementation in rainy tropical savanna conditions: the triad host-gastrointestinal nematodes-environment.

The objective of this study was to evaluate the influence of increasing levels of extruded urea (EU, Amireia®) in the diet of lambs naturally infected by gastrointestinal nematodes on the interactions in the host-pasture-soil components in edaphoclimatic conditions of the tropical rainy savanna. A total of 60 Texel lambs with a mean initial weight of 20.7 ± 0.87 and mean age of 2.5 ± 0.70 months were distributed in a completely randomized design, in five treatments consisting of different levels of EU supplementation viz., 0, 6, 12, 18, and 24 g 100 kg-1 live weight (LW). The performance of lambs, parasitological variables, gastrointestinal nematodes (NGIs), and larvae recovery in pasture and soil were evaluated. The highest animal performance was observed in animals that received 0 to 18 g kg-1 LW (146.0 g day-1) and the lowest in animals supplemented with 24 g kg-1 LW (81.0 g day-1) of EU. The body condition score (BCS) was similar in the animals (P > 0.05). Parasitic infection did not differ as a function of EU level (P > 0.05). Eggs of Haemonchus spp., Trichostrongylus spp., Cooperia spp., and Oesophagostomum spp. were found. The largest amount of larvae in the L1/L2 and L3 stages was recovered in the pastures occupied by the animals that received supplementation 0 g kg-1 LW of EU (750 larvae), the smallest in those that the animals received 6 g 100 kg-1 LW of EU (54 larvae). The presence of larvae in the L1/L2 stages changed significantly (P < 0.05) in the soil; in the other stages, it did not differ in the soil. Increasing levels of extruded urea do not influence the eggs per gram of feces (EPG) count. The 0 to 18 g 100 kg-1 LW level maintains animal performance, BCS and FAMACHA©. There is less dispersal of NGI larvae in pasture and soil when EU levels increase in the edaphoclimatic conditions of the rainy tropical savannah, which suggests that this supplement can be implemented in the diet of beef lambs, in addition to to be a lower cost nitrogen source.

Donepezil Prevents Inhibition of Cerebral Energetic Metabolism Without Altering Behavioral Parameters in Animal Model of Obesity.

Obesity is characterized by chronic inflammation of low grade. The cholinergic anti-inflammatory pathway favors the reduction of the inflammatory response. In this work the effect of stimulation of the cholinergic anti-inflammatory pathway on SHIRPA behavioral test and mitochondrial respiratory chain activity in obese mice was evaluated. The animals were paired in four groups: saline + control diet; donepezil + control diet; saline + high-fat diet and donepezil + high-fat diet. 5 mg/kg/day orally of donepezil or saline were given 7 days before the beginning of the diet until completing 11 weeks of the experiment. Food intake and body weight were measured. At the end of the experiment the animals were submitted to the SHIRPA behavioral test, soon after they were killed by decapitation, the open abdominal cavity and the mesenteric fat were removed. The hypothalamus, hippocampus, prefrontal cortex, and striatum were removed for evaluation of the mitochondrial respiratory chain. It can be observed that donepezil prevented weight gain and food consumption, as well as a tendency to prevent the accumulation of mesenteric fat in obese animals. There was no behavioral change in obese animals, nor did the influence of donepezil on these parameters. On the other hand, donepezil did not prevent inhibition of complex I activity, prevented the inhibition of complex II, and showed a tendency to prevent IV complex activity inhibited in obesity. With these results it can be concluded that the activation of the cholinergic anti-inflammatory pathway is promising for the alterations found in obesity.

Oxidative stress and mitochondrial dysfunction contributes to postoperative cognitive dysfunction in elderly rats.

Postoperative cognitive dysfunction (POCD) is defined by cognitive impairment determined by neuropsychological tests from before to after surgery. Several mechanisms have been proposed in this bidirectional communication between the immune system and the brain after surgery. We aimed at understanding the mechanisms underlying POCD elderly rats in an experimental tibial fracture model. Elderly male Wistar rats were subjected to tibial fracture (TF) model. Control (sham) and fracture (TF) groups were followed to determine nitrite/nitrate concentration; oxidative damage to lipids and proteins; the activity of antioxidant enzymes (superoxide dismutase-SOD and catalase-CAT), mitochondrial respiratory chain enzymes, and creatine kinase (CK); and BDNF levels in the hippocampus and prefrontal cortex (at 24 h and at seven days) and cognitive function through habituation to the open field task and novel object recognition task (only at seven days). TF group presented increased concentration of nitrite/nitrate, hippocampal lipid peroxidation at seven days, protein oxidative damage in the prefrontal cortex and hippocampus at 24 h, decreased antioxidant activity in both structures on the first postoperative day and compromised function of the mitochondrial respiratory chain complexes as well as the CK enzyme. In addition, the levels of BDNF were reduced and memory function was impaired in the TF group. In conclusion, elderly rats submitted to an experimental model of tibial fracture displayed memory impairment accompanied by an increase in oxidative stress, mitochondrial dysfunction and reduced neurotrophin level.

Acute modification in plasma lipid levels in ultramarathon runners.

We aimed to evaluate the effects of a 24-h ultramarathon, an aerobic test of high physical load, on lipid profile and apolipoproteins B (ApoB) and A1 (ApoA1) levels, minimally modified low-density lipoprotein (LDL), and oxidised LDL. Prospective evaluation of 16 male athletes who participated in an ultramarathon run, where the objective was to run the greatest distance possible in 24 h. Fourteen participants completed the run. The mean distance achieved was 133.1 km (maximum of 169.6 km). There was a trend in reduction of triglycerides and total cholesterol (P = 0.06 and 0.05, respectively), without significant modifications in high-density lipoprotein, LDL and ApoA1 levels (P = 0.16; 0.55 and 0.67). There was a marked reduction in ApoB levels (P < 0.001), correlated directly to the distance covered (Pearson R = 0.68). Accordingly, an increase in the LDL/ApoB ratio was observed. The stress of this physical activity was not associated to an increase in minimally modified LDL or oxidised LDL. Lipid profile levels were not acutely altered by prolonged physical activity. Similarly, there was no evidence of greater oxidation of LDL over a 24-h period of physical activity. The reduction in ApoB was directly proportional to the distance covered, suggesting an acute positive change in phenotype of LDL molecules.

Influence of anti-obesity strategies on brain function in health and review: A review.

The aim of this review was to investigate in the literature the application of strategies such as low carbohydrate diet (LCD), ketogenic diet (KD) and intermittent fasting (IF) and their effects on the CNS. We performed a narrative review of the literature. The search was specifically carried out in PubMed, selecting articles in English, which had the following keywords: obesity, central nervous system, low carb diet, ketogenic diet and intermittent fasting, using the narrative review methodology. The studies found show that the benefits of the LCD, KD and IF strategies, at the CNS level, have a strong influence on the mechanisms of hunger and satiety, as well as on the reduction of food reward and show improvement in memory and mood influenced by the interventions.

Therapeutic effects of the gold nanoparticle on obesity-triggered neuroinflammation: a review.

Introduction: Obesity is considered a chronic non-communicable disease characterised by excess body fat. In recent years the prevalence of obesity has grown a lot. Individuals with obesity store the excess of nutrients consumed in the form of fat in adipose tissue, and generate an imbalance of this tissue, where there is the secretion of adipocytokines, which contributes to a peripheral and central inflammatory picture, reaching the central nervous system (CNS), generating neuroinflammation. There is still no effective and safe therapy for the treatment of obesity, many of the drugs marketed has serious side effects. Therefore, there is a search for therapies aimed mainly at reducing inflammation.Objective: In this work the possibility of using a new therapeutic option for obesity will be explored, using nanotechnology. Nanotechnology has gained prominence in recent years for being a promising technology for treatment and as a molecule-in-the-light in inflammatory diseases. Gold nanoparticles (GNP) stand out among nanomaterials because they demonstrate anti-inflammatory characteristics by various pathways, and have been widely used in the treatment of inflammatory diseases, including in the CNS, demonstrating excellent results.Result: Thus, the use of GNP for the treatment of obesity is promising due to the inflammatory state of obesity, thus acting as anti-inflammatory at the peripheral and central levels.

Cannabis sativa as a Treatment for Obesity: From Anti-Inflammatory Indirect Support to a Promising Metabolic Re-Establishment Target.

Introduction: Obesity is defined as an excess of accumulation of fat that can be harmful to health. Storage of excess fat in the adipose tissue triggers an inflammatory process, which makes obesity a low-grade chronic inflammatory disease. Obesity is considered a complex and multifactorial disease; hence, no intervention strategy appears to be an ideal treatment for all individuals. Therefore, new therapeutic alternatives are often studied for the treatment of this disease. Currently, herbal medicines are gaining ground in the treatment of obesity and its comorbidities. In this context, much attention is being paid to Cannabis sativa derivatives, and their therapeutic functions are being widely studied, including in treating obesity. Objective: Highlight the pharmacological properties of Δ9-tetrahydrocannabivarin (THCV), Δ9-tetrahydrocannabidinol (THC), and cannabidiol (CBD), the predominant isolated components of Cannabis sativa, as well as its therapeutic potential in the treatment of obesity. Methods: This is a narrative review that shows the existing scientific evidence on the clinical application of Cannabis sativa as a possible treatment for obesity. Data collection was performed in the PubMed electronic database. The following word combinations were used: Cannabis and obesity, Cannabis sativa and obesity, THCV and obesity, THC and obesity, CBD and obesity, and Cannabis sativa and inflammation. Results: Evidence shows that Cannabis sativa derivatives have therapeutic potential due to their anti-inflammatory properties. In addition, people who use cannabis have a lower body mass index than those who do not, making the plant an option to reduce and reverse inflammation and comorbidities in obesity. Conclusion: It is concluded that phytocannabinoids derived from Cannabis sativa have therapeutic potential due to its anti-inflammatory, antioxidant, and neuroprotective properties, making the plant a study option to reduce and reverse inflammation and comorbidities associated with obesity.

The impact of obesity-related neuroinflammation on postpartum depression: A narrative review.

Obesity is currently one of the most serious health problems, affecting 13% of the world's adult population. Obesity is characterized by persistent low-grade chronic inflammation that assumes systemic proportions and triggers several associated metabolic diseases. Furthermore, obesity has been associated with an increased occurrence of central disorders such as impaired cognitive function, reward system dysfunction, and depression. In summary, there is a quantitative reduction in the release of neurotransmitters in depression. Postsynaptic cells capture lower concentrations of neurotransmitters, which leads to a functional reduction in the central nervous system (CNS). Globally, approximately 15-65% of women experience depressive symptoms during pregnancy, depending on their location. Depressive symptoms persist in some women, leading to postpartum depression (PPD). Thus, obesity may be considered a risk factor for PPD development. This study aimed to synthesize studies on the impact of obesity-related neuroinflammation and PPD. We conducted a narrative review of the relevant literature. The search was performed in electronic databases, specifically PubMed, selecting articles in English published from 2014 to 2021 using the narrative review methodology.

Treatment with isolated gold nanoparticles reverses brain damage caused by obesity.

In this study, we performed two experiments. In the first experiment, the objective was to link gold nanoparticles (GNPs) with sodium diclofenac and/or soy lecithin and to determine their concentration in tissues and their toxicity using hepatic and renal analyzes in mice to evaluate their safety as therapeutic agents in the subsequent treatment of obesity. In the second experiment, we evaluated the effect of GNPs on inflammatory and biochemical parameters in obese mice. In the first experiment, we synthesized and characterized 18 nm GNPs that were administered intraperitoneally in isolation or in association with sodium diclofenac and/or soy lecithin in mice once daily for 1 or 14 days. Twenty-four hours after the single or final administration, the animals were euthanized, following which the tissues were removed for evaluating the concentration of GNPs, and serum samples were collected for hepatic and renal analysis. Hepatic damage was evaluated based on the levels of alanine aminotransferase (ALT), whereas renal damage was evaluated based on creatinine levels. A higher concentration of GNPs was detected in the tissues upon administration for 14 days, and there were no signs of hepatic or renal damage. In the second experiment, the mice were used as animal models of obesity and were fed a high-fat diet (obese group) and control diet (control group). After eight weeks of high-fat diet administration, the mice were treated with saline or with GNPs (average size of 18 nm) at a concentration of 70 mg/L (70 mg/kg) once a day, for 14 days, for 10 weeks. Body weight and food intake were measured frequently. After the experiment ended, the animals were euthanized, serum samples were collected for glucose and lipid profile analysis, the mesenteric fat content was weighed, and the brains were removed for inflammatory and biochemical analysis. In obese mice, although GNP administration did not reduce body and mesenteric fat weight, it reduced food intake. The glucose levels were reversed upon administration of GNPs, whereas the lipid profile was not altered in any of the groups. GNPs exerted a beneficial effect on inflammation and oxidative stress parameters, without reverting mitochondrial dysfunction. Our results indicate that the intraperitoneal administration of GNPs for 14 days results in a significant GNP concentration in adipose tissues, which could be an interesting finding for the treatment of inflammation associated with obesity. Based on the efficacy of GNPs in reducing dietary intake, inflammation, and oxidative stress, they can be considered potential alternative agents for the treatment of obesity.

Audiological assessment of children with HIV/AIDS: a meta-analysis.

OBJECTIVE: To analyze the results of the audiological evaluation of children with HIV and AIDS. DATA COLLECTION: Systematic review carried out in May 2019 in the Web of Science, PubMed, SciELO, and Scopus databases. Case reports and original articles were included, with no limitationsregarding country or year of publication. DATA SYNTHESIS: 278 articles were identified; 26 were included, in which HIV/AIDS was shown to be a risk factor for hearing loss (OR=5.364; p=0.00). The studies used different audiological exams, with varying methodologies. There was no difference regarding the type of hearing loss (p=0.119). CONCLUSION: Longitudinal studies using the same type of examination at all stages are suggested, to allow better monitoring of the effects of HIV on the child's hearing,and studies that provide more methodological details. The knowledge of the influence of HIV on the child's auditory system may lead to the promotion of measures that minimize the prevalence of hearing loss, allow an early diagnosis and timely rehabilitation, so as not to compromise child development.

Mitochondrial dysfunction in obesity.

Obesity leads to various changes in the body. Among them, the existing inflammatory process may lead to an increase in the production of reactive oxygen species (ROS) and cause oxidative stress. Oxidative stress, in turn, can trigger mitochondrial changes, which is called mitochondrial dysfunction. Moreover, excess nutrients supply (as it commonly is the case with obesity) can overwhelm the Krebs cycle and the mitochondrial respiratory chain, causing a mitochondrial dysfunction, and lead to a higher ROS formation. This increase in ROS production by the respiratory chain may also cause oxidative stress, which may exacerbate the inflammatory process in obesity. All these intracellular changes can lead to cellular apoptosis. These processes have been described in obesity as occurring mainly in peripheral tissues. However, some studies have already shown that obesity is also associated with changes in the central nervous system (CNS), with alterations in the blood-brain barrier (BBB) and in cerebral structures such as hypothalamus and hippocampus. In this sense, this review presents a general view about mitochondrial dysfunction in obesity, including related alterations, such as inflammation, oxidative stress, and apoptosis, and focusing on the whole organism, covering alterations in peripheral tissues, BBB, and CNS.

Fulminant hepatitis in a patient with secondary syphilis.

Despite the increasing incidence of syphilis and due to its wide variety of clinical manifestations, syphilis remains an under-diagnosed condition. We report an unusual case of secondary syphilis presenting with acute hepatitis and skin lesions, confirmed based on positive treponemal and non-treponemal assays. Despite adequate diagnosis and treatment, the patient developed fulminant hepatitis and brain death. This atypical presentation emphasizes the importance of high clinical suspicion in recognizing syphilis as an etiology for unexplained acute hepatitis, allowing early diagnosis and treatment and possibly avoiding severe complications such as fulminant hepatic failure.

Utilização de serviços odontológicos por pacientes em tratamento oncológico / Use of dental services by patients in oncological treatment

Introdução: a busca por atendimento odontológico é um parâmetro importante para averiguar como os indivíduos compreendem a saúde bucal. Objetivo: avaliar a utilização de serviços odontológicos e fatores associados em pacientes oncológicos em Minas Gerais, Brasil. Material e método: estudo transversal, realizado com uma amostra de 441 pacientes adultos frequentadores de uma associação voluntária de apoio a pacientes oncológicos no Estado de Minas Gerais, Brasil. O desfecho foi avaliado por meio do autorrelato de consulta odontológica no último ano. As variáveis independentes incluíram condições socioeconômicas, saúde geral e relacionada ao câncer, saúde bucal e cuidados odontológicos. As associações entre o desfecho e as variáveis independentes foram testadas por meio de regressão logística bivariada e múltipla, sendo os resultados expressos por meio de odds ratio (OR) e intervalos de confiança de 95% (IC95%). Resultado: a prevalência de consulta odontológica no último ano foi de 33,3%. Os indivíduos que possuem entre quatro e sete (OR: 1,80; IC95%: 1,02-3,18) e aqueles com oito ou mais anos de estudo (OR: 3,20; IC95%: 1,07-9,60) apresentaram maiores, enquanto os edêntulos (OR: 0,44; IC95%: 0,21-0,92) apresentaram menores chances de consulta odontológica no último ano, independentemente de condições socioeconômicas, saúde geral e saúde bucal. Conclusão: foi baixa a procura por consulta odontológica no último ano entre os pacientes oncológicos. Além disso, houve desigualdades relacionadas à escolaridade e ao número de dentes remanescentes na utilização dos serviços. A identificação e priorização dos grupos com acesso desfavorável aos serviços são fundamentais no planejamento da prestação de cuidados odontológicos a essa população.

Introduction: the search for dental care is an important parameter to determine how individuals understand the oral health. Objective: to evaluate the use of dental services and associated factors in cancer patients in Minas Gerais, Brazil. Material and method: a cross-sectional study carried out with a sample of 441 adult patients attending a voluntary association to support cancer patients in the State of Minas Gerais, Brazil. The outcome was assessed through self-report of dental appointments in the last year. Independent variables included socioeconomic status, general and cancer-related health, oral health, and dental care. The associations between the outcome and the independent variables were tested using bivariate and multiple logistic regression, and the results were expressed as odds ratios (OR) and 95% confidence intervals (95%CI). Result: the prevalence of dental appointments in the last year was 33.3%. Individuals who have between four and seven (OR: 1.80; 95%CI: 1.02-3.18) and those who have eight or more years of schooling (OR: 3.20; 95%CI: 1.07-9 .60) had greater, whereas, the edentulous (OR: 0.44; 95%CI: 0.21-0.92) had less odds to have had a dental appointment in the last year, independently of socioeconomic status, general health and oral health conditions. Conclusion: recent dental care was uncommon among cancer patients. Furthermore, there were inequalities related to schooling and the number of remaining teeth in the use of services. The identification and prioritization of groups with unfavorable access to services are fundamental in planning the provision of dental care to this population.

A Randomized Open-Label Trial to Assess the Effect of Plant Sterols Associated with Ezetimibe in Low-Density Lipoprotein Levels in Patients with Coronary Artery Disease on Statin Therapy.

Consumption of food products enriched with plant sterols and the use of ezetimibe reduce cholesterol absorption in the intestine and effectively reduce low-density lipoprotein (LDL) plasma levels. We evaluated the therapeutic effect of the ezetimibe+plant sterol association in patients with coronary artery disease still not reaching recommended lipid levels despite the use of statins. We performed a prospective open-label study with 41 patients with stable coronary disease and LDL >70 mg/dL. Patients were randomized into four groups for a 6-week treatment: the control (CT) group remained on the same statin therapy, the ezetimibe (EZ) group received 10 mg/day of ezetimibe, the plant sterol (PS) group received spread enriched with 2 g of plant sterols, and the ezetimibe+PS (EZ+PS) group received 10 mg/day EZ +2 g PS. Initial mean LDL level was 97.4 ± 31.1 mg/dL in control group, 105.1 ± 23.1 mg/dL in EZ group, 95.4 ± 27.7 mg/dL in PS group, and 97.0 ± 8.3 mg/dL in EZ+PS group (P > .05). After 6 weeks of treatment, LDL of patients slightly increased in the control group (+8.9%; P > .05) and dropped in EZ group (-19.1%; P = .06), PS group (-16.6%; P = .01), and EZ+PS group (-27.3%; P < .01). Mean LDL levels after treatment were 70.5 ± 17.9 mg/dL in EZ+PS group, lower than the other groups (control was 106.1 ± 34.9 mg/dL, EZ group was 85.0 ± 35.6 mg/dL, and PS was 79.6 ± 29.7 mg/dL) (P = .05 variance analysis factor [ANOVA]). Body weight, body-mass index, and glucose plasma levels did not change significantly after intervention. The combination of PS+ezetimibe was associated with lower LDL levels and suggests beneficial therapeutic effect against major cardiovascular events.

Condições de saúde dos recém-nascidos brasileiros filhos de migrantes venezuelanas em condições de abrigamento na cidade de Boa Vista-RR / Health conditions of brazilian newborns children of venezuelan migrants in housing conditions in the city of Boa Vista-RR

Considerando o contexto atual da migração venezuelana, resolveu-se buscar compreender as condições de saúde dos recém-nascidos que vivem nos abrigos para migrantes venezuelanos em Boa Vista ­ RR, bem como todo o contexto de nascimento e assistência de saúde a essas crianças. Trata-se de um estudo de análise descritiva, de natureza quantitativa, delineada para analisar as condições de nascimento e verificar a ocorrência de complicações precoces e tardias de recémnascidos brasileiros filhos de migrantes venezuelanas em condição de abrigamento no município de Boa Vista-RR. Os dados foram coletados através de entrevista semiestruturada com auxílio de questionário com perguntas mistas. Os resultados mostraram a idade gestacional ao nascimento, a maior ocorrência do parto normal; mais da metade apresentaram distúrbio respiratório; 24,6% foi internado em unidade neonatal; a imunização teve alta cobertura; 69,2% realizaram o teste do pezinho; o aleitamento materno exclusivo foi relatado por 61,5% das entrevistadas; 29,2% dos neonatos haviam apresentado alguma condição clínica. Este estudo mostrou que uma diversidade de fatores acarreta fragilidades na saúde dessas crianças, como cuidados com a criança, vacinação do RN, triagem neonatal, acompanhamento do crescimento e desenvolvimento. Desta forma, evidencia-se a necessidade de interação entre equipe de saúde dos abrigos e da atenção básica para sensibilização das mulheres quanto a importância do acompanhamento de saúde da criança.

Depressão em pacientes com doença renal crônica em hemodiálise e transplante renal / Depression in patients with chronic renal disease on hemodialysis and renal transplantation

O desenvolvimento de pesquisas, diante da relevância do tema, propicia suporte teórico, favorecendo a atuação da assistência multidisciplinar, no intuito de fortalecer o vínculo terapêutico, a relação com a família e o cuidado de modo integral. O objetivo deste estudo foi revisar os principais aspectos clínicos da depres- são entre pacientes com doença renal crônica em hemodiálise e transplantados renais com base nas evidências científicas atuais. O aumento da expectativa de vida acarreta a elevação da inci- dência das doenças crônicas não transmissíveis ­ dentre elas a doença renal crônica ­, que são vistas como fatores que afetam o paciente, tanto no âmbito físico como no psicológico, gerando a associação de doenças crônicas com distúrbios psicoafetivos. Estudos prévios mostram que a depressão é três a cinco vezes mais prevalente no estágio avançado da doença renal crôni- ca do que na população em geral. A prevalência de depressão nos pacientes em hemodiálise está em torno de 20% a 40%, re- presentado uma questão de saúde pública. Apesar de sua alta prevalência, a depressão é subdiagnosticada e subtratada, pois os profissionais de saúde assemelham os sintomas depressivos com os das doenças crônicas, focalizando apenas nos aspectos físicos da enfermidade. É essencial que os profissionais da saúde estejam qualificados para reconhecer as manifestações iniciais para o diagnóstico correto da depressão, posto que esse distúrbio possui ligação direta com o sucesso terapêutico.

The development of research, given the relevance of the theme, provides theoretical support favoring the performance of multi- disciplinary care, to strengthen the therapeutic bond, the rela- tionship with the family, and care in an integral way. The objective of this study was to review the main clinical aspects of depression among patients with chronic kidney disease on hemodialysis and with kidney transplantation based on current scientific evidence. The increase in life expectancy leads to an increase in the inciden- ce of noncommunicable chronic diseases, among them chronic kidney disease, which are seen as factors that affect the patient both physically and psychologically, leading to the association of chronic diseases with psycho-affective disorders. Previous studies show that depression is five to three times more prevalent in the advanced stage of chronic kidney disease than in the general po- pulation. The prevalence of depression in hemodialysis patients is around 20% to 40%, representing a public health issue. Despite its high prevalence, depression is underdiagnosed and undertrea- ted, because health professionals relate depressive symptoms to those of chronic diseases, focusing only on the physical aspects of the disease. It is essential that health care professionals are qualified to recognize the initial manifestations for the correct diagnosis of depression, since this disorder has a direct connec- tion with therapeutic success.

Desfechos perinatais relacionados a idade materna e comorbidades gestacionais nos nascimentos prematuros / Perinatal outcomes related to maternal age and gestational comorbidities in premature births

Objetivo: descrever os desfechos perinatais do binômio no nascimento prematuro, de acordo com a idade materna e as principais comorbidades gestacionais. Métodos: estudo descritivo e retrospectivo, com inclusão de todos os nascimentos prematuros de 2015.

High prevalence of subclinical hypothyroidism and nodular thyroid disease in patients on hemodialysis.

Chronic kidney disease has been known to affect thyroid hormone metabolism. Low serum levels of T3 and T4 are the most remarkable laboratorial findings. A high incidence of goiter and nodules on thyroid ultrasonography has been reported in patients with end-stage renal disease (ESRD). Our objective is to evaluate the prevalence of laboratorial and morphologic alterations in the thyroid gland in a cohort of patients with ESRD on hemodialysis (HD). Sixty-one patients with ESRD on HD were selected and compared with 43 healthy subjects matched by age, gender, and weight. Patients were submitted to thyroid ultrasonography. T3, free T4 (FT4), thyroid-stimulating hormone, antithyroglobulin, and antithyroperoxidase antibodies were measured. The mean age of patients with ESRD was 47.4 ± 12.3 and 61% were women. ESRD was mainly caused by hypertensive nephrosclerosis and diabetic nephropathy. Mean thyroid volume, as determined by ultrasonography, was similar in both groups. Patients with ESRD had more hypoechoic nodules when compared with the control group (24.1% vs. 7.9%, P = 0.056). Mean serum FT4 and T3 levels were significantly lower in patients with ESRD, and subclinical hypothyroidism was more prevalent in patients with ESRD (21.82% vs. 7.14% control group, P = 0.04). Titers of antithyroid antibodies were similar in both groups. ESRD was associated with a higher prevalence of subclinical hypothyroidism and lower levels of T3 and FT4. Almost a quarter of patients showed thyroid nodules >10 mm. Periodic ultrasound evaluation and assessment of thyroid function are recommended in patients with ESRD on HD.
