Understanding of the role of serum creatinine in a subset of the Brazilian population / Conhecimento de uma amostragem da população brasileira sobre a função da creatinina sérica

Abstract Introduction: Chronic kidney disease is usually asymptomatic, and its diagnosis depends on laboratory tests, with emphasis on serum creatinine and proteinuria. Objective: To assess knowledge on the role of serum creatinine as a biomarker of kidney function in a sample of the Brazilian population. Method: Cross-sectional observational study conducted in São Paulo (SP, Brazil), in which a random adult population was interviewed. Results: A total of 1138 subjects were interviewed, with a median age of 36 years old (27-52); 55.1% were female. Regarding the "creatinine" biomarker, 40.6% stated they had never performed such a test. When asked about their knowledge on the usefulness of this exam, only 19.6% knew its function. The other responses were "I don't know" (71.6%), evaluating heart function (0.9%) and liver function (7.8%). Of those who reported they had already taken a creatinine test, only 29.4% correctly identified the role of creatinine. When dividing the groups into "knows" and "does not know" the function of creatinine, a statistically significant difference (p < 0.05) was observed regarding level of education, female sex, being a healthcare student/worker, having ever measured creatinine, knowing someone with kidney disease and older age. In the multivariate analysis, the main variable related to knowing the creatinine role was having previously taken the test (OR 5.16; 95% CI 3.16-8.43, p < 0.001). Conclusion: There is a significant lack of knowledge about creatinine and its use in checkups. The results indicate that greater efforts are needed from healthcare professionals to raise awareness on the role of serum creatinine.

Resumo Introdução: A doença renal crônica costuma ser assintomática e seu diagnóstico depende da realização de exames laboratoriais, com destaque para a creatinina sérica e pesquisa de proteinúria. Objetivo: Avaliar em uma amostra da população brasileira o conhecimento sobre o papel da creatinina sérica como marcador de função renal. Método: Estudo observacional transversal realizado na cidade de São Paulo (SP, Brasil), em que foi entrevistada uma população adulta aleatória. Resultados: Foram entrevistados 1138 indivíduos, com idade mediana de 36 anos (27-52); 55,1% do sexo feminino. Com relação ao marcador "creatinina", 40,6% afirmaram que nunca realizaram tal dosagem. Quando questionados quanto ao conhecimento sobre a utilidade desse exame, somente 19,6% sabiam a sua função. As outras respostas foram "não sei" (71,6%), avaliar o funcionamento do coração (0,9%) e fígado (7,8%). Dos que afirmaram já terem realizado o exame de creatinina, somente 29,4% acertaram a função da creatinina. Ao dividir os grupos em "sabe" e "não sabe" a função da creatinina, percebeu-se diferença estatisticamente significante (p < 0,05) em relação ao grau de escolaridade, sexo feminino, ser aluno/trabalhador da saúde, ter dosado creatinina alguma vez, conhecer alguém com doença renal e maior idade. Na análise multivariada, a principal variável relacionada com conhecer a função da creatinina foi ter realizado o exame anteriormente (OR 5,16; IC 95% 3,16-8,43, p < 0,001). Conclusão: Há grande desconhecimento sobre a creatinina e seu uso em check-ups. Os resultados indicam que é necessário maior esforço por parte dos profissionais de saúde para divulgar o papel da creatinina sérica.

Bacillus pumilus cellulitis with bacteremia in a person who injects drugs, living with HIV-HCV co-infection: a case report.

Bacillus pumilus (B. pumilus) is a ubiquitous spore-forming bacteria that has rarely been implicated in extraintestinal infections, mostly in immunocompromised hosts. The authors report a case of B. pumilus cellulitis with bacteremia in a person who injects drugs living with human immunodeficiency virus-hepatitis C virus (HIV-HCV) co-infection. Although similar cases have been reported for some species of the genus, namely Bacillus anthracis (B. anthracis) and Bacillus cereus (B. cereus), this case reinforces the importance of considering other Bacillus spp. as potential pathogens in skin and soft tissue infections and bloodstream infections related to intravenous drug use.

Tropical Sprue: A Rare Cause of Malabsorption Syndrome.

Chronic diarrhea is a common disorder in tropical regions, affecting residents, visitors, and even expatriates. It may stem from a myriad of infectious, inflammatory, and even malignant causes. In patients in whom no etiology has been found, tropical sprue (TS) is an important diagnosis to consider. We report the case of a 60-year-old man originally from Guatemala, presenting with chronic diarrhea and megaloblastic anemia due to severe vitamin B12 deficiency. Biopsies of the small bowel revealed partial villous atrophy and inflammatory infiltrate with the participation of eosinophils. The diagnosis of TS was established after exclusion of other causes of malabsorption syndrome. This is a disease of unknown etiology with complex and multifactorial pathophysiology, with an important component of intestinal dysbiosis. Antibiotics and vitamin supplementation are the pillars of therapy. Awareness of this disorder is essential in preventing delayed diagnosis and subsequent morbidity.

Mitotherapy prevents peripheral neuropathy induced by oxaliplatin in mice.

Oxaliplatin (OXA) is an antineoplastic agent used for the treatment of cisplatin-resistant tumours, presenting lower incidence of nephrotoxicity and myelotoxicity than other platinum-based drugs. However, OXA treatment is highly associated with painful peripheral neuropathy, a well-known and relevant side effect caused by mitochondrial dysfunction. The transfer of functional exogenous mitochondria (mitotherapy) is a promising therapeutic strategy for mitochondrial diseases. We investigated the effect of mitotherapy on oxaliplatin-induced painful peripheral neuropathy (OIPN) in male mice. OIPN was induced by i.p. injections of oxaliplatin (3 mg/kg) over 5 consecutive days. Mechanical (von Frey test) and cold (acetone drop test) allodynia were evaluated between 7 and 17 days after the first OXA treatment. Mitochondria was isolated from donor mouse livers and mitochondrial oxidative phosphorylation was assessed with high resolution respirometry. After confirming that the isolated mitochondria were functional, the organelles were administered at the dose of 0.5 mg/kg of mitochondrial protein on days 1, 3 and 5. Treatment with OXA caused both mechanical and cold allodynia in mice that were significant 7 days after the initial injection of OXA and persisted for up to 17 days. Mitotherapy significantly prevented the development of both sensory alterations, and attenuated body weight loss induced by OXA. Mitotherapy also prevented spinal cord ERK1/2 activation, microgliosis and the increase in TLR4 mRNA levels. Mitotherapy prevented OIPN by inhibiting neuroinflammation and the consequent cellular overactivity in the spinal cord, presenting a potential therapeutic strategy for pain management in oncologic patients undergoing OXA treatment.

Caracterización Epidemiológica de los Pacientes de la Clínica Ambulatoria del Departamento de Psiquiatría de la Infancia y la Adolescencia de un Hospital Universitario de Paraguay: Estudio Trienal

El tema de la salud mental en niños y adolescentes requiere mayor atención. Por lo tanto, este estudio tuvo como objetivo determinar las características de los pacientes de consulta externa de un centro especializado de un hospital universitario paraguayo. Este estudio empleó una serie retrospectiva, no probabilística, de casos consecutivos. Se examinaron las historias clínicas de pacientes de ambos sexos, de entre 2 y 17 años de edad, que solicitaron consulta en el Departamento de Psiquiatría del Niño y del Adolescente del Hospital de Clínicas entre julio de 2021 y julio de 2023, y que fueron diagnosticados con un trastorno mental según la CIE-10. Se recogieron datos demográficos y clínicos de 447 pacientes, representando 1278 consultas. La mayoría de los pacientes eran mujeres (57,7%), con una edad media de 13 ± 3 años. La mayoría de los pacientes (57,3%) procedían del Departamento Central, el 61,5% eran de zonas rurales y el 72% no tenían seguro médico. Los diagnósticos más frecuentes fueron episodios depresivos (F32), otros trastornos de ansiedad (F41), trastornos de conducta (F91) y trastornos específicos de la personalidad (F60). Los resultados de este estudio proporcionan información crucial sobre la salud mental de niños y adolescentes, que es esencial para informar las políticas de salud mental, asignar recursos y formar a los profesionales sanitarios encargados de atender a este grupo de pacientes.

The topic of mental health in children and adolescents requires increased attention. Therefore, this study aimed to determine the characteristics of outpatient clinic patients at a specialized center within a Paraguayan University Hospital. This study employed a retrospective, non-probabilistic series of consecutive cases. The medical records of patients of both sexes, aged between 2 and 17 years, who sought consultation at the Department of Child and Adolescent Psychiatry of the Hospital de Clínicas between July 2021 and July 2023, and were diagnosed with a mental disorder according to the ICD-10, were examined. Demographic and clinical data were collected from 447 patients, representing 1278 consultations. The majority of the patients were female (57.7%), with a mean age of 13 ± 3 years. Most patients (57.3%) were from the Central Department, 61.5% were from rural areas, and 72% did not have medical insurance. The most frequent diagnoses were depressive episodes (F32), other anxiety disorders (F41), conduct disorders (F91), and specific personality disorders (F60). The findings of this study provide crucial information on child and adolescent mental health, which is essential for informing mental health policies, allocating resources, and training healthcare professionals tasked with caring for this patient group.

Drug use among medical students in São Paulo, Brazil: a cross-sectional study during the coronavirus disease 2019 pandemic

ABSTRACT BACKGROUND: Medical students demonstrate higher rates of substance use than other university students and the general population. The challenges imposed by the coronavirus disease 2019 (COVID-19) pandemic raised significant concerns about mental health and substance use. OBJECTIVES: Assess the current prevalence of substance use among medical students at the University of São Paulo and evaluate the impact of the COVID-19 pandemic on drug consumption. DESIGN AND SETTING: A cross-sectional study was conducted on 275 medical students from the University of São Paulo Medical School (São Paulo, Brazil) in August 2020. METHODS: Substance use (lifetime, previous 12 months, and frequency of use before and during the COVID-19 pandemic) and socioeconomic data were assessed using an online self-administered questionnaire. Symptoms of depression were assessed using the Patient Health Questionnaire-9. RESULTS: Alcohol was the most consumed substance in their lifetime (95.6%), followed by illicit drugs (61.1%), marijuana (60%), and tobacco (57.5%). The most commonly consumed substances in the previous year were alcohol (82.9%), illicit drugs (44.7%), marijuana (42.5%), and tobacco (36%). Students in the first two academic years consumed fewer substances than those from higher years. There was a decreasing trend in the prevalence of most substances used after the COVID-19 pandemic among sporadic users. However, frequent users maintained their drug use patterns. CONCLUSION: The prevalence of substance use was high in this population and increased from the basic to the clinical cycle. The COVID-19 pandemic may have affected the frequency of drug use and prevalence estimates.

Hope, resilience and subjective happiness among general population of Paraguay in the post COVID-19 pandemic.

BACKGROUND: Positive mental health includes not only the absence of mental disorders but also the presence of subjective well-being, good coping strategies for life stress, and strategies for adapting to community life. It is well known that the COVID-19 pandemic has challenged mental health in general population worldwide. However, research has not measured protective factors for mental health in the general population after the declared end of pandemic by the World Health Organization. METHODS: This observational, cross-sectional study surveyed 591 Paraguayan participants aged ⩾18 years, who were recruited through an online survey. Demographic characteristics, socioeconomic status were collected as well as mental health and validated tools for hope, resilience, subjective happiness were administered. RESULTS: Of the participants, 81.6% were women, 54% were married or in a relationship and 90.7% reported an university education. The main source of stress was economic issues (30.3%). A total of 22.7% had been previously diagnosed with a mental disorder, 22.2% had consulted a mental health professional and 10.8% had consumed prescription drugs. 42.6% reported flourishing, 36.2% reported moderate and 21.2% reported languishing mental health. CONCLUSIONS: This large survey has shown that most of participants reported a flourishing mental health with high ratings at hope, resilience, and subjective happiness scales. Also, the main sources of stress were economic issues, not consequently related to the pandemic. This may add evidences to the international debate on the long term effects of the global pandemic and probably suggests that recovery processes have been collectively adopted in Paraguay.

Adhesion dynamics of functionalized nanocarriers to endothelial cells: a dissipative particle dynamics study.

Targeted drug delivery to endothelial cells utilizing functionalized nanocarriers (NCs) is an essential procedure in therapeutic and diagnosis therapies. Using dissipative particle dynamics simulation, NCs have been designed and combined with an endothelial environment, such as the endothelial glycocalyx (EG) layer, receptors, water, and cell wall. Furthermore, the energy landscapes of the functionalized NC with the endothelial cell have been analyzed as a function of properties such as the shape, size, initial orientation, and ligand density of NCs. Our results show that an appropriate higher ligand density for each particular NC provides more driving forces than barriers for the penetration of the NCs. Herein we report the importance of shell entropy loss for the NC shape effect on the adhesion and penetration into the EG layer. Moreover, the rotation of the disc shape NC as a wheel during the penetration is an extra driving force for its further inclusion. By increasing the NCs' size larger than the appropriate size for each particular ligand density, due to an increase in the NCs' shell entropy loss, the barriers surpass the driving forces for NC penetration. Furthermore, the parallel orientation provides the NCs with the best penetration capabilities. However, the rotation of the disc shape NCs enhances their diffusion in the perpendicular orientation too. Overall, our findings highlight the crucial role of the shell entropy loss in governing the penetration of NCs. Besides, studying NCs with a homogeneous ligand composition enabled us to cross barriers and probe energetics after the complete inclusion of the NCs.

Dermatitis Artefacta: A Practical Guide for Diagnosis and Management.

Dermatitis artefacta (DA) is a psycho-dermatologic condition based on patients' behavioral patterns, characterized by an intentional production of cutaneous lesions on their own skin. The clinical presentation can be highly variable. Patients with DA seldom seek psychological support or psychiatric consultation. More often, they seek help from their primary care physician or dermatologist. This review article aims to provide a practical guide for the diagnosis and management of AD and affected patients. A broad literature search was performed using the PubMed and Google Scholar electronic online databases, using key words "dermatitis artefacta", "diagnosis", "management", and "psychodermatology". The search was limited to English and Spanish language articles and was supplemented with themed books and book chapters. DA can occur in a variety of clinical presentations, and physicians should suspect DA in patients with a history of psychiatric disorders or extensive use of healthcare services. The ultimate goal of DA treatment may be a proper referral to mental health services. However, the prognosis is poor even when successful mental health referrals are achieved, with low recovery rates. A useful approach may include the suggestion that a mental health provider can help with the anxiety and the distress generated by the lesions: in this case in this case it will be crucial to discuss this with the mental health provider after obtaining informed consent from the patient. Considering the difficulty in promoting patients' adherence to treatment, the ideal setting for DA treatment is a psycho-dermatologic clinic, where both dermatologic and psychological interventions can be seamlessly integrated.

Drug overdose deaths in Brazil between 2000 and 2020: an analysis of sociodemographics and intentionality

Objectives: To examine drug overdose records in Brazil from 2000 to 2020, analyzing trends over time in overdoses and overall sociodemographic characteristics of the deceased. Methods: Using data from the Brazilian Mortality Information System (Sistema de Informações sobre Mortalidade), we identified records from 2000-2020 in which the underlying cause-of-death was one of the following codes: X40-X45 (accidental poisoning), X60-X65 (intentional poisoning), or Y10-Y15 (undetermined intentionality poisoning). The Brazilian dataset included 21,410 deaths. We used joinpoint regression analysis to assess changes in trends over time. Results: People who died of drug overdoses in Brazil between 2000 and 2020 had a mean age of 38.91 years; 38.45% were women, and 44.01% were identified as White. Of the overdose deaths, 44.70% were classified as intentional and 32.12% were classified as unintentional. Among the identified drugs, stimulants were the most common class. However, most records did not report which drug was responsible for death. Conclusion: Sociodemographic trends in overdose deaths in Brazil must guide country-specific policies. Nevertheless, data collection protocols must be improved, particularly regarding the drug used in overdoses.

Effects of Caffeine on Main Symptoms in Children with ADHD: A Systematic Review and Meta-Analysis of Randomized Trials.

(1) Background: Attention-deficit/hyperactivity disorder (ADHD) is typically treated with stimulant medications, which may lead to several adverse effects. Recent animal studies have shown that caffeine can improve the symptoms of ADHD. This systematic review and meta-analysis sought to evaluate the effect of caffeine on ADHD symptoms in children. (2) Methods: PubMed, Embase, and Cochrane databases were searched for randomized controlled trials comparing caffeine with placebo in children, comparing overall symptoms of ADHD, inattention, hyperactivity, and impulsivity. (3) Results: We included seven RCTs in the systematic review for qualitative assessment, with 104 patients aged 5 to 15 years. Four of these studies (n = 76) were included in the meta-analysis. After qualitative analysis, four studies indicated no improvement in any of the ADHD symptoms compared with placebo. One study showed improvement in ADHD symptoms based on 1 of 5 scales applied. One study indicated significant improvement in general symptoms, inattention, and hyperactivity. One study indicated improvement in sustained attention but a worsening of impulsivity. In contrast, when using a quantitative analysis of the general symptoms of ADHD, the data showed no significant difference when comparing placebo with caffeine (standardized mean difference -0.12; 95% CI -0.44 to 0.20; p = 0.45; I2 = 0%). (4) Conclusion: overall, the totality of the evidence suggests no significant benefit of caffeine over placebo in the treatment of children with ADHD.

Pharmacological Treatment of Alcohol Cravings.

(1) Background: The treatment of substance addiction is challenging and has persisted for decades, with only a few therapeutic options. Although there are some recommendations for specific treatments for Alcohol Use Disorder (AUD), there is no specific medication used to treat alcohol cravings, which could benefit millions of patients that are suffering from alcoholism. Cravings, or the urge to use drugs, refer to the desire to experience the effects of a previously experienced psychoactive substance. (2) Methods: We included original studies of alcohol abuse or dependence extracted from a controlled, blind, pharmacological treatment study which presented measures and outcomes related to alcohol cravings. (3) Results: Specific drugs used for the treatment of alcoholism, such as Naltrexone and Acamprosate, have had the best results in relieving craving symptoms, as well as promoting abstinence. Baclofen and anticonvulsants such as Gabapentin and Topiramate have shown good results in promoting abstinence and the cessation of cravings. (4) Conclusions: Specific drugs used for the treatment of alcoholism to obtain the best results can be considered the gold standard for promoting abstinence and relieving cravings. Anticonvulsants and Baclofen also had good results, with these medications being considered as second-line ones. Varenicline is an option for alcohol dependents who also concomitantly ingest tobacco.
