ABSTRACT
Depression will be the disease with the highest incidence worldwide by 2030. Data indicate that postmenopausal women have a higher incidence of mood disorders, and this high vulnerability seems to be related to hormonal changes and weight gain. Although research evaluating the profile of metabolites in mood disorders is advancing, further research, maintaining consistent methodology, is necessary to reach a consensus. Therefore, the objective of the present study was to carry out an exploratory analysis of the plasma polar metabolites of pre- and postmenopausal women to explore whether the profile is affected by depression. The plasma analysis of 50 polar metabolites was carried out in a total of 67 postmenopausal women, aged between 50 and 65 years, either without depression (n = 25) or with depression symptoms (n = 42), which had spontaneous onset of menopause and were not in use of hormone replacement therapy, insulin, or antidepressants; and in 42 healthy premenopausal women (21 without depression and 21 with depression symptoms), aged between 40 and 50 years and who were not in use of contraceptives, insulin, or antidepressants. Ten metabolites were significantly affected by depression symptoms postmenopause, including adenosine (FDR = 3.778 × 10-14), guanosine (FDR = 3.001 × 10-14), proline (FDR = 1.430 × 10-6), citrulline (FDR = 0.0001), lysine (FDR = 0.0004), and carnitine (FDR = 0.0331), which were down-regulated, and dimethylglycine (FDR = 0.0022), glutathione (FDR = 0.0048), creatine (FDR = 0.0286), and methionine (FDR = 0.0484) that were up-regulated. In premenopausal women with depression, oxidized glutathione (FDR = 0.0137) was down-regulated, and dimethylglycine (FDR = 0.0406) and 4-hydroxyproline (FDR = 0.0433) were up-regulated. The present study provided new data concerning the consequences of depression on plasma polar metabolites before and after the establishment of menopause. The results demonstrated that the postmenopausal condition presented more alterations than the premenopausal period and may indicate future measures to treat the disturbances involved in both menopause and depression.

O trauma dental é uma ocorrência involuntária que pode acometer pacientes de ambos os sexos e várias idades, passando desde uma concussão, pela fratura e exposição pulpar até a avulsão dental. Objetivo: descrever um caso clínico do efeito do biocerâmico em dente com ápice reabsorvido devido a traumatismo. Relato de caso: Paciente do sexo masculino, 26 anos, hipertenso, que procurou o serviço de urgência da Policlínica de Odontologia da Universidade do Estado do Amazonas (POUEA), apresentando como queixa principal dor difusa e espontânea em dente na região anterior da mandíbula com histórico de traumatismo dentário, tendo fraturado a coroa sem procurar atendimento odontológico na época. No exame clínico bucal observou-se perda da coroa do elemento 41, presença de dor à palpação em fundo de vestíbulo, com resposta positiva aos testes de percussão vertical e horizontal, assim como ausência de sensibilidade ao frio. Na radiografia periapical do elemento foi visto que o dente encontrava-se com o ápice reabsorvido. O tratamento foi realizado em três sessões, sendo feito o acesso do elemento, instrumentação e preenchimento do canal com biocerâmico Biodentine para apicificação. Posteriormente foi feita a proservação clínica radiográfica do paciente onde observou-se início de neoformação óssea apical e ausência de sintomatologia. Consideração final: biocerâmicos possuem bioatividade capaz de formar hidroxiapatita promovendo a reparação apical.
ABSTRACT
A pesquisa propõe conhecer a saúde bucal, analisando o perfil epidemiológico, identificando a prevalência e necessidade de tratamento dos pacientes pediátricos internados na enfermaria do Hospital e Pronto Socorro da Criança Zona Sul em Manaus (PSC), no Amazonas. Este estudo transversal e observacional descritivo foi realizado com pacientes internados atendidos no PSC no período de setembro de 2022 a fevereiro de 2023. A coleta de dados foi realizada presencialmente nos dias semanais através análise dos prontuários, utilização de uma ficha odontológica e avaliação clínica. Observou-se a presença de pacientes do gênero masculino, superior ao gênero feminino e com faixa etária maior entre 2 a 9 anos de idade. Obteve-se resultados positivos acerca da condição bucal dos pacientes, sendo 44,26% considerada no critério Boa. A doença mais prevalente entre os pacientes internados nas enfermarias, corresponde à Síndrome Nefrótica com 25,35%. Conclui-se que a condição bucal mais prevalente entre os pacientes que se encontram internados na enfermaria é a condição bucal Boa. Isto justifica-se devido a presença de um projeto de extensão completado no hospital, que evidencia que a presença do cirurgião dentista na equipe multidisciplinar nas enfermarias dos hospitais é indispensável, pois ele é o profissional capacitado a manter e restabelecer a saúde bucal.
The research aims to investigate oral health by analyzing the epidemiological profile, identifying the prevalence and treatment needs of pediatric patients admitted to the ward of the South Zone Children's Hospital and First Aid Station in the city of Manaus, in the state of Amazonas. This cross-sectional and descriptive observational study was conducted with admitted patients treated at the South Zone Children's Hospital and First Aid Station between September 2022 and February 2023. The data collection was conducted in person on weekly days through the analysis of medical records, the use of a dental form, and clinical evaluation. It was observed that male patients were more numerous than female patients, and that the age range of 2 to 9 years old had a higher representation. Positive results were obtained regarding the oral condition of the patients, with 44.26% considered to be in the Good category. The most prevalent disease among the patients admitted to the wards is Nephrotic Syndrome, accounting for 25.35%. It is concluded that the most prevalent oral condition among patients admitted to the ward is the Good oral condition. This is justified by the presence of an extension project conducted in the hospital, which shows that the presence of the dental surgeon in the multidisciplinary team in the hospital wards is essential, as they are the professionals capable of maintaining and restoring oral health.

Obesity and depression, disorders associated with inflammation, have high incidences in women. Understanding the derangements present in the initial phase of obesity may point to factors that could help avoiding disease aggravation. The present study aimed at investigating the effects of a 6-months interdisciplinary therapy for weight loss in women with grade I obesity. Before and after the therapy, 37 middle-aged women donated blood and responded to questionnaires for depression and anxiety symptoms. Inflammatory parameters were evaluated in serum and a preliminary screening of the plasma proteome was performed. The therapy decreased anthropometric, psychological scores, and serum levels of inflammatory parameters. Depression and anxiety scores correlated positively with some inflammatory parameters. The proteomic analysis showed changes in proteins related to cholesterol metabolism and inflammatory response. Interdisciplinary therapy improves anthropometric and inflammatory statuses and ameliorating psychological symptoms. The decrease of MCP-1 levels after interdisciplinary therapy has not been reported so far, at the best of our knowledge. The present demonstration of positive associations of inflammatory markers and psychological scores indicate that these mediators may be useful to monitor psychological status in obesity. The present proteome data, although preliminary, pointed to plasma alterations indicative of improvement of inflammation after interdisciplinary therapy.

Venous thromboembolism is a complex multifactorial disease considered the most common cause of preventable deaths in hospitalized patients. Recommendations about pharmacological venous thromboembolism prophylaxis in adult hospitalized patients are available in clinical practice guidelines for optimization of healthcare delivery and improvement of patient outcomes. We conducted a systematic review of clinical practice guidelines using ADAPTE to synthesize recommendations for pharmacological prophylaxis of venous thromboembolism in hospitalized medical patients at a medium complexity university hospital. Recommendations for pharmacological prophylaxis were extracted from seven clinical practice guidelines considered of high quality after assessment with the Appraisal of Guidelines for Research and Evaluation (AGREE II) instrument. These recommendations will support discussion with specialists and implementation of practices in the setting of the hospital studied.

ABSTRACT
BACKGROUND: The incapacity to store lipids in adipose tissue in Congenital Generalized Lipodystrophy (CGL) causes hypoleptinemia, increased appetite, ectopic fat deposition and lipotoxicity. CGL patients experience shortened life expectancy. The plasma lipidomic profile has not been characterized fully in CGL, nor has the extent of dietary intake in its modulation. The present work investigated the plasma lipidomic profile of CGL patients in comparison to eutrophic individuals at the fasted state and after a breakfast meal. METHOD: Blood samples from 11 CGL patients and 10 eutrophic controls were collected after 12 h fasting (T0) and 90 min after an ad libitum fat-containing breakfast (T90). The lipidomic profile of extracted plasma lipids was characterized by non-target liquid chromatography mass spectrometry. RESULTS: Important differences between groups were observed at T0 and at T90. Several molecular species of fatty acyls, glycerolipids, sphingolipids and glycerophospholipids were altered in CGL. All the detected fatty acyl molecular species, several diacylglycerols and one triacylglycerol species were upregulated in CGL. Among sphingolipids, one sphingomyelin and one glycosphingolipid species showed downregulation in CGL. Alterations in the glycerophospholipids glycerophosphoethanolamines, glycerophosphoserines and cardiolipins were more complex. Interestingly, when comparing T90 versus T0, the lipidomic profile in CGL did not change as intensely as it did for control participants. CONCLUSIONS: The present study found profound alterations in the plasma lipidomic profile of complex lipids in CGL patients as compared to control subjects. A fat-containing breakfast meal did not appear to significantly influence the CGL profile observed in the fasted state. Our study may have implications for clinical practice, also aiding to a deeper comprehension of the role of complex lipids in CGL in view of novel therapeutic strategies.

Our previous behavioral and molecular data indicate a central role of the dorsal hippocampal formation (dHF) in recent conditioned lick suppression memory. The purpose of this study was to investigate the role of the dHF in recent and remote memory of conditioned lick suppression employing proteomic analysis. Two or 40 days after conditioning, the rats were subjected to a retention test and were then euthanized after 24 hr for dHF collection. We identified 1,165 proteins and quantified 265 proteins. Upregulation of five proteins and downregulation of 21 proteins were found on postconditioning Day 2. Additionally, four proteins were upregulated and 21 proteins were downregulated on postconditioning Day 40. Integrated pathway analysis of the proteomics data indicated changes in the myelin sheath, neuron generation and differentiation, regulation of neurogenesis and synaptic vesicle transport, axonal development, and the growth cone. Our findings provide further support for the role of the dHF in conditioned lick suppression memory and novel insights into the molecular changes that are correlated with recent and remote memory in the dHF, which may be a target for cognitive enhancers.

OBJECTIVE: The objective of this study was to assess the quality of clinical practice guidelines (CPGs) for the pharmacological treatment of depression along with their recommendations and factors associated with higher quality. DESIGN: We conducted a systematic review that included CPGs for the pharmacological treatment of depression in adults. DATA SOURCES: We searched for publications from 1 January 2011 to 31 December 2021, in MEDLINE, Cochrane Library, Embase, PsycINFO, BVS and 12 other databases and guideline repositories. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included CPGs containing recommendations for the pharmacological treatment of depression in adults at outpatient care setting, regardless of whether it met the U.S. National Academy of Medicine criteria, or not. If a CPG included recommendations for both children and adults, they were considered. No language restriction was applied. DATA EXTRACTION AND SYNTHESIS: Data extraction was also conducted independently and in duplicate, a process that was validated in a previous project. The quality of the CPGs and their recommendations were assessed by three independent reviewers using Appraisal of Guidelines for Research and Evaluation (AGREE II) and Appraisal of Guidelines for Research and Evaluation-Recommendations Excellence (AGREE-REX). A CPG was considered to be of high quality if AGREE II Domain 3 was ≥60%; while their recommendations were considered high if AGREE-REX Domain 1 was ≥60%. RESULTS: Seventeen out of 63 (27%) CPGs were classified as high quality, while 7 (11.1%) had high-quality recommendations. The factors associated with higher-scoring CPGs and recommendations in the multiple linear regression analyses were 'Handling of conflicts of interest', 'Multiprofessional team' and 'Type of institution'. 'Inclusion of patient representative in the team' was also associated with higher-quality recommendations. CONCLUSIONS: The involvement of professionals from diverse backgrounds, the handling of conflicts of interest, and the inclusion of patients' perspectives should be prioritised by developers aiming for high-quality CPGs for the treatment of depression.

INTRODUCTION: Depression is a serious and widespread mental health disorder. A significant proportion of patients with depression fail to remit after two antidepressant treatment trials, a condition named treatment-resistant depression (TRD). Clinical practice guidelines (CPGs) are instruments aimed to improve diagnosis and treatment. This study objective is to systematically appraise the quality and elaborate a comparison of high-quality CPGs with high-quality recommendations aimed at TRD. METHODS AND ANALYSIS: We searched several specialized databases and organizations that develop CPGs. Independent researchers assessed the quality of the CPGs and their recommendations using AGREE II and AGREE-REX instruments, respectively. We selected only high-quality CPGs that included definition and recommendations for TRD. We investigated their divergencies and convergencies as well as weak and strong points. RESULTS: Among seven high-quality CPGs with high-quality recommendations only two (Germany's Nationale Versorgungs Leitlinie-NVL and US Department of Veterans Affairs and Department of Defense-VA/DoD) included specific TRD definition and were selected. We found no convergent therapeutic strategy among these two CPGs. Electroconvulsive therapy is recommended by the NVL but not by the VA/DoD, while repetitive transcranial magnetic stimulation is recommended by the VA/DoD but not by the NVL. While the NVL recommends the use of lithium, and a non-routine use of thyroid or other hormones, psychostimulants, and dopaminergic agents the VA/DoD does not even include these drugs among augmentation strategies. Instead, the VA/DoD recommends ketamine or esketamine as augmentation strategies, while the NVL does not mention these drugs. Other differences between these CPGs include antidepressant combination, psychotherapy as a therapeutic augmentation, and evaluation of the need for hospitalization all of which are only recommended by the NVL. CONCLUSIONS: High-quality CPGs for the treatment of depression diverge regarding the definition and use of the term TRD. There is also no convergent approach to TRD from currently high-quality CPGs.

AIMS: We report a rare case of late diagnosis of malignant osteopetrosis in a 36-year-old male patient due to multiple intraoral sinus tracts and trismus. CASE REPORT: The patient reported a history of facial scars that could not be attributed to the older external fistulas that were present and various complicated dental extractions since infancy. In addition, the patient had not been previously diagnosed with any other significant diseases other than blindness since infancy. Computed tomography revealed a marble-like sclerotic pattern of all cranial bones, a thickened parietal bone, and a narrowing of the encephalic space and the optic canal. Further laboratory and imaging studies revealed complete sclerosed bone of the chest and pelvis, anemia, reticulocitosis, extramedular hematopoiesis, altered dehydrogenasis lactate, and acid phosphatasis. An interdisciplinary treatment was initiated with medical and dental care monitoring. The patient is still receiving attention after 4 years of follow-up. CONCLUSIONS: The outcome of this case represents the daily challenges faced by interdisciplinary care providers and reveals pearls and pitfalls that can serve as a reference for professional practice in such cases.

ABSTRACT
Smaller adipocytes are related to the reversal of metabolic disorders, suggesting that molecules that can act in the adipogenesis pathway are of great interest. The objective of this study was to investigate the effect of Ginkgo biloba extract (GbE) in modulating the differentiation in preadipocytes. 3T3-L1 preadipocytes were differentiated for 7 days into adipocytes without (control group) and with GbE at 1.0 mg/mL. Lipid content and gene expression were analyzed on day 7 (D7) by Oil Red O staining and PCR Array Gene Expression. Western blotting analysis of the key adipogenesis markers was evaluated during the differentiation process at days 3 (D3), 5 (D5), and 7 (D7). GbE increased lipid content and raised the gene expression of the main adipogenesis markers. Key proteins of the differentiation process were modulated by GbE, since C/EBPß levels were decreased, while C/EBPα levels were increased at D7. Regarding the mature adipocytes' markers, GbE enhanced the levels of both FABP4 at D5, and perilipin at D3 and D5. In summary, the present findings showed that GbE modulated the adipogenesis pathway suggesting that the treatment could accelerate the preadipocyte maturation, stimulating the expression of mature adipocyte proteins earlier than expected.
ABSTRACT
INTRODUCTION: Depression is a serious and widespread mental health disorder. Although effective treatment does exist, a significant proportion of patients with depression fail to respond to antidepressant treatment trials, a condition named treatment-resistant depression. Efficient approach should be given this condition in order to revert the burden caused by depression. Clinical practice guidelines (CPGs) are evidence-based health promotion instruments to improve diagnosis and treatment. CPGs recommendations for treatment-resistant depression must be trustworthy. The objective of the proposed study is to systematically identify, appraise the quality of CPGs for the treatment of depression and elaborate a synthesis of recommendations for treatment-resistant depression of CPGs considered to be of high quality and with high quality recommendations. METHODS AND ANALYSIS: We will search the databases of organizations, such as PubMed, Embase, Cochrane Library, PsycInfo, and the Virtual Health Library, and organizations that develop CPGs. Three independent researchers will assess the quality of the CPGs and their recommendations using the AGREE II and AGREE-REX instruments, respectively. Given the identification of divergences and convergences as well as weak and strong points among high quality CPGs, our work may help developers, clinicians and eventually patients. ETHICS AND DISSEMINATION: No ethical approval is required for a systematic review, as no patient data will be used. The research results will be disseminated in conferences and submitted to a peer reviewed journal.

OBJECTIVE: To assess similarities and differences in the recommended sequence of strategies among the most relevant clinical practice guidelines (CPGs) for the treatment of depression in adults with inadequate response to first-line treatment. DATA SOURCES: We performed a systematic review of the literature spanning January 2011 to August 2020 in Medline, Embase, Cochrane Library and 12 databases recognised as CPGs repositories. CPGs quality was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II). STUDY SELECTION: The eligibility criteria were CPGs that described pharmacological recommendations for treating depression for individuals aged 18 years or older in outpatient care setting. We included CPGs considered of high-quality (≥80% in domain 3 of AGREE II) or recognised as clinically relevant. DATA EXTRACTION: Two independent researchers extracted recommendations for patients who did not respond to first-line pharmacological treatment from the selected CPGs. RESULTS: We included 46 CPGs and selected 8, of which 5 were considered high quality (≥80% in domain 3 of AGREE II) and 3 were recognised as clinically relevant. Three CPGs did not define inadequate response to treatment and 3 did not establish a clear sequence of strategies. The duration of treatment needed to determine that a patient had not responded was not explicit in 3 CPGs and was discordant in 5 CPGs. Most CPGs agree in reassessing the diagnosis, assessing the presence of comorbidities, adherence to treatment, and increase dosage as first steps. All CPGs recommend psychotherapy, switching antidepressants, and considering augmentation/combining antidepressants. CONCLUSION: Relevant CPGs present shortcomings in recommendations for non-responders to first-line antidepressant treatment including absence and divergencies in definition of inadequate response and sequence of recommended strategies. Overall, most relevant CPGs recommend reassessing the diagnosis, evaluate comorbidities, adherence to treatment, increase dosage of antidepressants, and psychotherapy as first steps.

Introduction: Thyroid hormones exert multiple physiological effects essential to the maintenance of basal metabolic rate (BMR), adaptive thermogenesis, fat metabolism, growth, and appetite. The links between obesity and the hormones of the thyroid axis, i.e., triiodothyronine (T3), thyroxine (T4), and thyrotropin (TSH), are still controversial, especially when considering children and adolescents. This population has high rates of overweight and obesity and several treatment approaches, including nutritional, psychological, and physical exercise interventions have been used. Understanding the importance of the hormones of the thyroid axis in the recovery from overweight and obesity may help directing measures to the maintenance of a healthy body composition. The present scoping review was carried out to analyze studies evaluating these hormonal levels throughout interventions directed at treating overweight and obesity in children and adolescents. The main purpose was to ascertain whether the hormones levels vary during weight loss. Methods: We selected for analysis 19 studies published between 1999 and 2022. Results: Most of the studies showed that changes in different anthropometric indicators, in response to the multidisciplinary interventions, correlated positively with free T3 (fT3), total T3 (TT3), and TSH. With respect to free T4 (fT4) and total T4 (TT4). Discussion: The most common finding was of unchanged levels and, hence, no significant association with weight loss. Moreover, thyroxine supplementation has failed to affect the response to the interventions. Further studies are necessary to elucidate the relevance of the variations in hormone levels to the establishment of overweight/obesity and to the recovery from these conditions in children/adolescents.

ABSTRACT
Abstract Clinical pharmacists have been increasing their participation mainly through actions aimed at patient care, with international studies demonstrating favorable cost-benefit ratio from pharmacists interventions. However, there are few studies carried out in Brazil about the subject. This study aims to assess the economic impact of pharmaceutical interventions (PIs) in a hospital setting performed in October 2018. Each performed PI was registered and associated with the direct cost of drugs for economic impact analysis. A total of 185 PIs were evaluated, comprising 106 patients. The most intervened drugs were antibiotics, presenting the greatest economic impact, R$2,370. The total economic impact was R$2,578, mainly in the Pediatric Intensive Care Unit that represented R$1,701. Regarding the economic impact by PI as the "Suspension of drug without indication" saved R$1,360 while the "Inclusion of required drugs" cost R$807. It was estimated that the savings would be R$30,936 and, if PIs were performed at day zero, the savings would be R$79,728 per year. An average of 1.75 PI per patient was performed with an economic impact of R$14 per PI. Our results showed that clinical pharmacist's role in the evaluation of pharmacotherapy is important for patients' health and represents a positive economic impact.
ABSTRACT
Abstract Safety culture is a product of values, attitudes, skills, and behavioral patterns, and it determines the commitment of the management to a secure organization. The evaluation of safety culture in hospitals helps to identify and manage the relevant patient safety issues in hospital routines and working conditions proactively. Thus, this study is aimed to evaluate patient safety culture in all the departments of a university hospital of medium complexity. This study employed a cross-sectional and analytical design employed in the Portuguese version of the Hospital Survey on Patient Safety Culture. A sample of all hospital staff participated in this study, which was conducted from December 2016 to May 2017. The percentage of positive responses was calculated to identify the strong and weak areas in patient safety. Of the 413 questionnaires distributed, 368 valid responses were returned. The response rate was, therefore, 89%. The overall percentage of positive responses was 50.3%. The "Supervisor/manager expectations and actions promoting patient safety" dimension obtained the highest percentage of positive responses (67.1%). The "Nonpunitive response to error" dimension was considered the weakest for safety culture, with only 22.9% positive responses. Furthermore, most professionals (70.6%) did not report any events in the previous 12 months. Nevertheless, 69.5% of participants considered patient safety within their unit/work area as "very good" or "great." The results showed that the employees' perception of patient safety diverged from the reality within the institution. Therefore, efforts should be made to promote an acceptable safety culture in all hospital areas.
ABSTRACT
Previous studies have shown that Ginkgo biloba extract (GbE) reduces food intake and body mass gain and regulates proteins related to lipid metabolism in obese rats. In ovariectomized rats, GbE restored the hippocampal and hypothalamic serotonergic system activity, favoring the spontaneous feeding decrement. Considering the promising hypophagic effect of GbE, this study aimed to investigate the effect of a single acute dose on hypothalamic pathways that regulate feeding behavior in male rats. Four-month-old Wistar male rats received either a single acute oral GbE dose (500 mg/kg) or vehicle. Food intake and body mass were measured after 1, 4, 12, and 24 h. Rats were euthanized, and hypothalami were removed for mRNA quantification of anorexigenic (POMC/CART) and orexigenic (AgRP/NPY) neuropeptides, leptin/serotonin receptors (5HT1A, 5HT1B, 5HT2C), and serotonin transporters. We also investigated POMC, 5-HT1B, and 5-HT2C protein levels. A single acute GbE dose induced the hypothalamic POMC, CART, and 5-HT2C gene expression but failed to modify orexigenic effectors. No alterations in food intake, body mass, and hypothalamic protein levels were observed. In summary, the present findings demonstrate the rapid stimulation of pivotal hypothalamic anorexigenic pathways in response to a single GbE administration, reinforcing the GbE hypophagic activity. However, more studies are necessary to evaluate its potential as an appetite modulator.
