Dificuldades no enfrentamento da hanseníase no tratamento e pós-alta / Difficulties coping with leprosy during treatment and post-discharge

Objetivo: Identificar as principais dificuldades durante o tratamento e pós-alta de pacientes com hanseníase atendidos na Atenção Secundária em Teresina-Piauí e seu perfil epidemiológico. Métodos: Trata-se de um estudo transversal, quantitativo, que identificou necessidades e levantou dados de pacientes em tratamento de hanseníase em um serviço de referência localizado em Teresina-Piauí. Resultados: Na amostra, observou-se predomínio de pacientes do sexo masculino (58,5%), casados ou em união estável (54,7%), com ensino fundamental completo (62,3%), renda de 1 a 2 salários mínimos (66,0%) e residentes em Teresina-Piauí (90,6%). A idade média dos pacientes foi 53 anos. 9,4% abandonaram o tratamento. No pós-alta, 90,6% dos pacientes apresentaram algum tipo de sequela. Notou-se que a ausência de conhecimento sobre a hanseníase retardou o acesso ao sistema de saúde. Verificou-se associação significativa entre a variável presença de sequela e alteração de sensibilidade (p=0,014). Os relatos de preconceito foram mais frequentes durante o tratamento (41,5%), em relação ao pós-alta (15,1%). Conclusão: A hanseníase ainda é uma doença negligenciada, estigmatizada e de difícil diagnóstico, sendo necessário maiores investimentos em políticas públicas para a difusão de conhecimentos sobre a doença.

Objective: To identify the main difficulties and the epidemiological profile during treatment and post-discharge in patients with leprosy treated at the Secondary Care level in Teresina-Piauí.Methods: This is a cross-sectional and quantitative study that identified needs and surveyed data from patients undergoing leprosy treatment in a reference service located in Teresina-Piauí.Results: In the sample, there was predominance of male patients (58.5%), married or in a stable union (54.7%), with complete Elementary School (62.3%), incomes of 1 to 2 minimum wages (66.0%) and residents of Teresina-Piauí (90.6%). The mean age of the patients was 53years old. 9.4% abandoned the treatment. 90.6% of the patients presented some type of sequelae post-discharge. It was noticed that lack of knowledge about leprosy delayed access to the health system. A significant association was verified between the "presence of sequelae" variable and change in sensitivity (p = 0.014). The reports about prejudice were more frequent during the treatment (41.5%) than in the post-discharge period(15.1%). Conclusion: Leprosy is still a neglected, stigmatized and difficult to diagnose disease, with a need for greater investments in public policies to disseminate knowledge about the disease. Descriptors: Leprosy; Therapy; Health Profile; Knowledge; Social Stigma.

Fournier gangrene - would you KISS it?

Fournier gangrene is a disease characterized by necrotizing fasciitis of the perineal and genital region, resulting from synergistic polymicrobiotic infection. Most infections can be localized to a cutaneous, urethral, or rectal source and can culminate in a fulminant sepsis. Current state of the art is systemic broad-spectrum antibiotics and serial aggressive debridement which result in superficial perineal defect of wide dimensions. We compiled all the cases of Fournier gangrene that required reconstruction after debridement in Centro Hospitalar Universitário Lisboa Central from 2018 to 2022. Inclusion criteria were reconstruction for Fournier defects and patients' age 18 to 90 years old. Exclusion criteria were patients who didn't require reconstruction or didn't complete it due to death or transfer to another healthcare institution. Reconstructive procedures and complication rates are reported as whole numbers and percentages of total. The initial search yielded 32 patients. There were 2 (6.2%) patients with defects that healed by secondary intention, 6 (18.7%) with delayed primary closure, 4 (12.5%) with implantation of the testicle in a medial thigh pocket, 12 (37.5%) with skin grafts, 4 (12.5%) with scrotal advancement flaps, 2 (6.2%) with flaps, and 2 (6.2%) with flaps and skin grafts in combination. Four outcomes were evaluated: number of patients, defect size, method of reconstruction, and wound-healing complications. Most reconstructive techniques provide reliable coverage and protection of testicular function with an acceptable cosmetic result. The reconstructive options need to be patient tailored in order to achieve long lasting results with a minimum of postoperative morbidity.

Pulpal calcifications in orthodontically moved teeth: Scoping review.

Background: The application of forces during orthodontic treatment can induce pulpal calcifications, characterized by the deposition of mineralized tissue in the pulp cavity space, there may be repercussions on dental procedures, especially endodontic treatment. The objective of this article is to map the scientific evidence and any gaps in knowledge regarding the relationship between orthodontics and dental pulp calcifications. Material and Methods: The study comprised a scoping review whose guiding question was: "What is the scientific evidence of the association between pulpal calcifications and orthodontic treatment?" Two independent reviewers searched the PubMed, Scopus, and Web of Science databases and the grey literature. Original articles and observational and clinical trials, which addressed the repercussions on the pulp cavity of teeth submitted to orthodontic treatment, were included. There was no language restriction or limitation of the year of publication until October 2022. Results: After critical reading and applying the eligibility criteria, 11 studies were included in this scoping review: six observational and five experimental studies. A statistically significant association of orthodontic treatment with changes in pulp cavity volume and increased incidence of pulp stones was observed among the studies findings. Conclusions: The orthodontic force can promote changes in the dental pulp that may cause direct implications in other dental treatments, especially endodontic treatment. Key words:Dental pulp calcifications, pulp node, pulp obliteration, orthodontic treatment, orthodontics.

Molecular characterisation of tumours of the lacrimal apparatus.

AIMS: Malignant tumours of the lacrimal apparatus are rare and frequently show a poor prognosis, with no clear therapeutic standards. Characterisation of the genetic landscape of these rare tumours is sparse, and therefore therapeutics generally follow those of their common salivary gland counterparts. To further clarify the pathophysiology and discover potential therapeutic targets, we investigated the genetic landscape of eight tumours of the lacrimal apparatus. METHODS AND RESULTS: DNA and RNA sequencing were performed to identify genetic mutations and gene fusions. Immunohistochemistry, fluorescence in-situ hybridisation and reverse transcription-polymerase chain reaction followed by Sanger sequencing were performed to confirm the identified molecular alterations. Genetic alterations were detected in six tumours. Among five adenoid cystic carcinomas (ACC), four had confirmed alterations of MYB or MYBL1 genes, including a MYB::NFIB fusion, a MYBL1::NFIB fusion, a MYB amplification and a novel NFIB::THSD7B fusion. Mutations in genes encoding epigenetic modifiers, as well as NOTCH1, FGFR2 and ATM mutations, were also identified in ACCs. A carcinoma ex pleomorphic adenoma showed TP53 and CIC mutations and an amplification of ERBB2. A transitional cell carcinoma was associated with HPV16 infection. No genetic alteration was found for one adenocarcinoma, not otherwise specified. CONCLUSIONS: Our study highlights the variety of molecular alterations associated with lacrimal system tumours and emphasises the importance of molecular testing in these tumours, which can reveal potentially targetable mutations. Our results also reinforce the hypothesis of a common physiopathology of all ACCs, regardless of their primary location.

Systematic Review of Treatment Failure and Clinical Relapses in Leishmaniasis from a Multifactorial Perspective: Clinical Aspects, Factors Associated with the Parasite and Host.

Leishmaniasis is a disease caused by protozoa of the genus Leishmania. Treatment options are limited, and there are frequent cases of treatment failure and clinical relapse. To understand these phenomena better, a systematic review was conducted, considering studies published between 1990 and 2021 in Portuguese, English, and Spanish. The review included 64 articles divided into three categories. Case reports (26 articles) focused on treatment failure and clinical relapse in cutaneous leishmaniasis patients (47.6%), primarily affecting males (74%) and children (67%), regardless of the clinical manifestation. Experimental studies on the parasite (19 articles), particularly with L. major (25%), indicated that alterations in DNA and genic expression (44.82%) played a significant role in treatment failure and clinical relapse. Population data on the human host (19 articles) identified immunological characteristics as the most associated factor (36%) with treatment failure and clinical relapse. Each clinical manifestation of the disease presented specificities in these phenomena, suggesting a multifactorial nature. Additionally, the parasites were found to adapt to the drugs used in treatment. In summary, the systematic review revealed that treatment failure and clinical relapse in leishmaniasis are complex processes influenced by various factors, including host immunology and parasite adaptation.

Sociodemographic and Clinical Factors for Microcephaly Secondary to Teratogenic Infections in Brazil: An Ecological Study.

Microcephaly is a neurological condition characterized by anomalies in the growth of the cranial circumference. This study aims to examine the association between sociodemographic and clinical variables and the occurrence of secondary microcephaly in newborns in Brazil. It also aims to investigate the association between this congenital anomaly and teratogenic infections. This research adopts an observational approach with an ecological, descriptive, and analytical design. The sample includes infants aged ≤28 days and registered in the country's Live Births Information System from January 2015 to December 2021. Newborns were categorized into G1, consisting of newborns with one of the three infections (Zika, toxoplasmosis, or syphilis), and G2, consisting of newborns with two of the three infections. A total of 1513 samples were analyzed and divided into two groups: one infection (syphilis n = 423; toxoplasmosis n = 295; or Zika n = 739) and two infections (n = 56). The northeastern region of Brazil has the highest prevalence of microcephaly. Regarding the population profile, the Zika virus infection is more common among white mothers, while the syphilis infection is more common among black mothers. Among newborns with microcephaly, boys have a lower prevalence of toxoplasmosis infection, while girls have a lower prevalence of Zika virus infection. This study provides pertinent information on each infection and contributes to the epidemiologic understanding of the association between teratogenic infections and microcephaly.

Comprehensive Two-Dimensional Gas Chromatography in Petroleum Derived Samples: A Review on Advances in Source and Weathering Studies of Spilled Oil.

Since its introduction comprehensive two-dimensional gas chromatography (GC × GC) has been widely applied to analyze complex samples due to its enhanced peak capacity and selectivity, thereby increasing the number of identifiable peaks and improving coelution issues. Even though it is still undergoing development, GC × GC provides many advantages in the analysis of petroleum-derived samples, whether in reservoir geochemistry applications or in environmental studies associated with spilled oils. In general, it facilitates more thorough fingerprinting and compositional evaluation. In environmental studies, it helps enhance understanding of weathering processes and the environmental behavior of hydrocarbons, as its chromatographic retention indices can robustly estimate liquid vapor pressures, aqueous solubility and other physical chemical properties. This review presents a brief history of GC × GC instrumentation, discussing recent and significant advances in petroleum applications, from data handling techniques to reservoir geochemistry and environmental forensics, as well as some specific advantages achieved and certain limitations that continue to be encountered.

A defined roadmap of radial glia and astrocyte differentiation from human pluripotent stem cells.

Human gliogenesis remains poorly understood, and derivation of astrocytes from human pluripotent stem cells (hPSCs) is inefficient and cumbersome. Here, we report controlled glial differentiation from hPSCs that bypasses neurogenesis, which otherwise precedes astrogliogenesis during brain development and in vitro differentiation. hPSCs were first differentiated into radial glial cells (RGCs) resembling resident RGCs of the fetal telencephalon, and modulation of specific cell signaling pathways resulted in direct and stepwise induction of key astroglial markers (NFIA, NFIB, SOX9, CD44, S100B, glial fibrillary acidic protein [GFAP]). Transcriptomic and genome-wide epigenetic mapping and single-cell analysis confirmed RGC-to-astrocyte differentiation, obviating neurogenesis and the gliogenic switch. Detailed molecular and cellular characterization experiments uncovered new mechanisms and markers for human RGCs and astrocytes. In summary, establishment of a glia-exclusive neural lineage progression model serves as a unique serum-free platform of manufacturing large numbers of RGCs and astrocytes for neuroscience, disease modeling (e.g., Alexander disease), and regenerative medicine.

In Vitro Drug Susceptibility of a Leishmania (Leishmania) infantum Isolate from a Visceral Leishmaniasis Pediatric Patient after Multiple Relapses.

The parasitic protozoan Leishmania (Leishmania) infantum is the etiological agent of human visceral leishmaniasis in South America, an infectious disease associated with malnutrition, anemia, and hepatosplenomegaly. In Brazil alone, around 2700 cases are reported each year. Treatment failure can occur as a result of drug, host, and/or parasite-related factors. Here, we isolated a Leishmania species from a pediatric patient with visceral leishmaniasis that did not respond to chemotherapy, experiencing a total of nine therapeutic relapses and undergoing a splenectomy. The parasite was confirmed as L. (L.) infantum after sequencing of the ribosomal DNA internal transcribed spacer, and the clinical isolate, in both promastigote and amastigote forms, was submitted to in vitro susceptibility assays with all the drugs currently used in the chemotherapy of leishmaniasis. The isolate was susceptible to meglumine antimoniate, amphotericin B, pentamidine, miltefosine, and paromomycin, similarly to another strain of this species that had previously been characterized. These findings indicate that the multiples relapses observed in this pediatric patient were not due to a decrease in the drug susceptibility of this isolate; therefore, immunophysiological aspects of the patient should be further investigated to understand the basis of treatment failure in this case.

Microwave-Assisted Digestion of Polyurethane Foam as an Alternative to Elution: Solid Phase Extraction of Cd(II) and Pb(II) for Their Determination in Swimming Pool Waters.

In this work, a separation/preconcentration method is proposed for the determination of Cd(II) and Pb(II) in swimming pool waters, using ammonium pyrrolidine dithiocarbamate (APDC) as a complexing agent and unloaded polyurethane foam (PUF) as a sorbent. The proposed method was optimized, and the defined optimal conditions were a pH of 7, 30 min of shaking time, 400 mg of PUF, and 0.5% (m/v) of the APDC solution. The release of Cd(II) and Pb(II) from the solid phase was achieved through the total digestion of PUF using a microwave-assisted acid approach with a 10.5 mol·L-1 HNO3 solution. The methodology was applied to four samples of swimming pool water for the determination of Cd(II) and Pb(II) using graphite furnace atomic absorption spectrometry (GF AAS). The limits of detection and quantification obtained were 0.02 and 0.06 µg·L-1 for Cd(II) and 0.5 e 1.8 µg·L-1 for Pb(II), respectively. We analyzed four samples of swimming pool waters, finding Cd concentrations between 0.22 and 1.37 µg·L-1. On the other hand, only one sample presented Pb concentration above the limit of quantification (11.4 µg·L-1). Recovery tests were performed by spiking the samples with known concentrations of the analytes, and recovery percentages between 82% and 105% were obtained.

Percepção dos pacientes sobre a busca pelo diagnóstico da hanseníase e o atendimento nas Redes de Atenção à Saúde / Patients' perception of the search for a leprosy diagnosis and care in health care networks

O objetivo do estudo foi avaliar a percepção dos pacientes quanto ao atendimento nas Redes de Atenção à Saúde, desde o surgimento dos sintomas até o diagnóstico de hanseníase. Trata-se de um estudo qualitativo com 15 pacientes com hanseníase atendidos em um centro de referência no estado do Piauí. A coleta de dados foi realizada entre agosto e setembro de 2022, com o uso de um roteiro de entrevista semiestruturado de três blocos: 1) perfil sociodemográfico e econômico; 2) dados clínicos; e 3) questões semidirigidas relacionadas ao itinerário terapêutico para o diagnóstico e tratamento. Foram incluídos pacientes com hanseníase em tratamento e idade superior a 18 anos. Excluiu-se aqueles que não responderam questionamentos essenciais para os objetivos do estudo ou tangenciaram o tema nesse sentido. Predominaram pacientes mulheres, casadas, com média de idade de 58 anos, ensino fundamental completo, que recebiam menos de um salário-mínimo, autodeclaradas como pardas, residentes em Teresina e com a forma multibacilar da doença. Após a análise de conteúdo, emergiram três categorias temáticas: 1) dificuldades no autorreconhecimento das manifestações clínicas da hanseníase; 2) itinerário terapêutico do usuário com hanseníase na rede de atenção à saúde; e 3) percepção dos pacientes com hanseníase sobre o aten-dimento dos profissionais de saúde. A percepção dos pacientes permite concluir que a busca pelo diagnóstico e o atendimento em saúde foi um processo longo e conflituoso até que estes chegassem a ser atendidos na Atenção Primária.(AU)

The aim of the study was to evaluate patients' perception regarding care in healthcare networks, from the emergence of symptoms to the diagnosis of leprosy. This is a qualitative study with 15 patients with leprosy managed in a referral center in the state of Piauí. Data collection occurred from August to September 2022, with the use of a 3-block semi-structured interview guide: 1) sociodemographic and economic profile; 2) clinical data; and 3) semi-structured questions about the therapeutic itinerary taken for diagnosis and treatment. Included were leprosy patients aged undergoing treatment aged 18 years or above. Excluded were patients who failed to answer questions that were essential to meet study objectives or who barely touched upon the subject. There was a predominance of female, married patients, self-declared as brown (parda), at a mean age of 58 years, with complete elementary school education that earned less than minimum wage and lived in Teresina, with the multibacillary form of disease. After content analysis, three thematic categories emerged: 1) difficulty in self-recognizing the clinical manifestations of leprosy; 2) therapeutic route of the leprosy user in the healthcare network; and 3) perception of leprosy patients about treatment provided by healthcare professionals. The patients' perception allows us to conclude that the search for diagnosis and health care was a long and conflicting process until they reached Primary Care.(AU)

Scalable generation of sensory neurons from human pluripotent stem cells.

Development of new non-addictive analgesics requires advanced strategies to differentiate human pluripotent stem cells (hPSCs) into relevant cell types. Following principles of developmental biology and translational applicability, here we developed an efficient stepwise differentiation method for peptidergic and non-peptidergic nociceptors. By modulating specific cell signaling pathways, hPSCs were first converted into SOX10+ neural crest, followed by differentiation into sensory neurons. Detailed characterization, including ultrastructural analysis, confirmed that the hPSC-derived nociceptors displayed cellular and molecular features comparable to native dorsal root ganglion (DRG) neurons, and expressed high-threshold primary sensory neuron markers, transcription factors, neuropeptides, and over 150 ion channels and receptors relevant for pain research and axonal growth/regeneration studies (e.g., TRPV1, NAV1.7, NAV1.8, TAC1, CALCA, GAP43, DPYSL2, NMNAT2). Moreover, after confirming robust functional activities and differential response to noxious stimuli and specific drugs, a robotic cell culture system was employed to produce large quantities of human sensory neurons, which can be used to develop nociceptor-selective analgesics.

Prevalence and risk factors of psychiatric symptoms and diagnoses before and during the COVID-19 pandemic: findings from the ELSA-Brasil COVID-19 mental health cohort.

BACKGROUND: There is mixed evidence on increasing rates of psychiatric disorders and symptoms during the coronavirus disease 2019 (COVID-19) pandemic in 2020. We evaluated pandemic-related psychopathology and psychiatry diagnoses and their determinants in the Brazilian Longitudinal Study of Health (ELSA-Brasil) São Paulo Research Center. METHODS: Between pre-pandemic ELSA-Brasil assessments in 2008-2010 (wave-1), 2012-2014 (wave-2), 2016-2018 (wave-3) and three pandemic assessments in 2020 (COVID-19 waves in May-July, July-September, and October-December), rates of common psychiatric symptoms, and depressive, anxiety, and common mental disorders (CMDs) were compared using the Clinical Interview Scheduled-Revised (CIS-R) and the Depression Anxiety Stress Scale-21 (DASS-21). Multivariable generalized linear models, adjusted by age, gender, educational level, and ethnicity identified variables associated with an elevated risk for mental disorders. RESULTS: In 2117 participants (mean age 62.3 years, 58.2% females), rates of CMDs and depressive disorders did not significantly change over time, oscillating from 23.5% to 21.1%, and 3.3% to 2.8%, respectively; whereas rate of anxiety disorders significantly decreased (2008-2010: 13.8%; 2016-2018: 9.8%; 2020: 8%). There was a decrease along three wave-COVID assessments for depression [ß = -0.37, 99.5% confidence interval (CI) -0.50 to -0.23], anxiety (ß = -0.37, 99.5% CI -0.48 to -0.26), and stress (ß = -0.48, 99.5% CI -0.64 to -0.33) symptoms (all ps < 0.001). Younger age, female sex, lower educational level, non-white ethnicity, and previous psychiatric disorders were associated with increased odds for psychiatric disorders, whereas self-evaluated good health and good quality of relationships with decreased risk. CONCLUSION: No consistent evidence of pandemic-related worsening psychopathology in our cohort was found. Indeed, psychiatric symptoms slightly decreased along 2020. Risk factors representing socioeconomic disadvantages were associated with increased odds of psychiatric disorders.

The Influence Between C-C Chemokine Receptor 5 Genetic Polymorphisms and the Type-1 Human Immunodeficiency Virus: A 20-Year Review.

Acquired immune deficiency syndrome (AIDS) is an infectious disease caused by the types 1 and 2 human immunodeficiency virus (HIV-1 and HIV-2). Clinical outcomes in patients are highly varied and delineated by complex interactions between virus, host, and environment, such as with help of co-receptors, for example, the C-C chemokine receptor 5 (CCR5). This work aimed to describe the scientific evidence relating the influence of CCR5 polymorphisms in association studies for HIV-1 disease susceptibility, severity, and transmissibility. This is a systematic review of the literature on single nucleotide polymorphisms (SNPs) and the deletion [Insertion and Deletion (Indel)] Δ32 of CCR5. The search for articles was based on the ScienceDirect, PubMed, and Coordination for the Improvement of Higher Education Personnel (CAPES) databases for the period between 2001 and 2021. The final sample consisted of 32 articles. †SNP rs1799987 is one of the genetic polymorphisms most associated with the criteria of susceptibility and severity of HIV-1, having distinct consequences in genotypic, allelic, and clinical analysis in the variability of investigated populations. As for the transmission character of the disease, the G mutant allele of rs1799987 corresponds to the highest positive association. ‡Furthermore, the results on Indel Δ32 corroborate the absence and rarity of this variant in some populations. Finally, mitigating the severity of cases, SNPs rs1799988 and rs1800023 obtained significant attribution in individuals in the studied populations. It is shown that the reported polymorphisms express significant influences for the evaluation of diagnostic, therapeutic, and prophylactic measures for HIV-1 having fundamental particularities in the molecular, genetic, and transcriptional aspects of CCR5.

Extraction and characterization of hyaluronic acid from the eyeball of Nile Tilapia (Oreochromis niloticus).

Hyaluronic acid (HA) is a biopolymer of enormous value aggregation for in general industry. The vitreous humor of the eyeball from Nile tilapia contains appreciable amounts of hyaluronic acid. In this sense, the aim of this work was to extract and characterize hyaluronic acid from the eyeball of the Nile tilapia for biomedical applications, adding value to fish industry residues. The characterization by infra-red (FTIR), 13C nuclear magnetic resonance (NMR) and high performance liquid chromatography (HPLC) confirmed that hyaluronic acid was obtained. The gel permeation chromatography (GPC) showed that the obtained material presents a low molecular mass (37 KDa). Thermogravimetry (TGA), differential scanning calorimetry (DSC), X-ray diffraction (XRD) analysis showed that the materials present a thermal stability superior to the commercial hyaluronic acid from Streptococcus equi, with a partially crystalline character. The cytotoxicity assay (MTT method) with fibroblast cells (L929) demonstrated that the extracted biopolymer besides not being cytotoxic, was able to stimulate cell proliferation. Therefore, the hyaluronic acid extracted from this source of residue constitutes a product with biotechnological potential, which has adequate quality for wide biomedical applications.

Formação para enfrentar a morte na perspectiva de futuros médicos / Training to cope with death from the perspective of future physicians / Formación para afrontar la muerte en la perspectiva de los futuros médicos

Resumo Ocasionalmente, a morte é considerada falha ou insucesso da medicina e a inabilidade em enfrentá-la pode gerar medo e frustração, interferindo nas decisões clínicas. Este estudo avaliou a percepção de estudantes de medicina quanto ao enfrentamento da morte, analisando seu preparo para lidar com essas situações e comparando seus perfis sociodemográfico, religioso e acadêmico. Realizou-se estudo transversal, quantitativo e qualitativo, com 294 estudantes de medicina da Bahia. Demonstrou-se que o estudante de medicina considera a morte um processo natural, mas não se sente totalmente preparado para lidar com a terminalidade da vida durante a prática clínica, possivelmente em razão das escassas discussões acadêmicas e da oferta insuficiente de conteúdo teórico-prático durante a formação. Homens com formação prévia e que tiveram contato pessoal e acadêmico com a morte foram associados à maior percepção de preparo para lidar com a terminalidade da vida, sem interferência de ciclo acadêmico e religião.

Abstract Occasionally, death is considered a medical failure and the inability to cope with it can generate fear and frustration, interfering with clinical decisions. This study assessed how medical students perceived coping with death, analyzing their preparedness to tackle these situations and comparing their sociodemographic, religious and academic profiles. This cross-sectional, quantitative and qualitative study was conducted with 294 medical students from Bahia. Results showed that medical students consider death to be a natural process, but do not feel fully prepared to address end of life during clinical practice, possibly due to the scarcity of academic discussions and the insufficient theoretical and practical content during training. Men with previous training and who had personal and academic contact with death were associated with a greater perceived preparedness to cope with death, without interference from academic level and religion.

Resumen En ocasiones, se percibe la muerte como un fracaso de la medicina, y la incapacidad de afrontarla puede generar miedo y frustración, interfiriendo en las decisiones clínicas. Este estudio evaluó la percepción de los estudiantes de medicina sobre el enfrentamiento a la muerte, analizando su preparación para lidiar con esta situación y comparando sus perfiles sociodemográficos, religiosos y académicos. En este estudio transversal, cuantitativo y cualitativo participaron 294 estudiantes de medicina de Bahía (Brasil). Los estudiantes de medicina perciben la muerte como algo natural, pero no se sienten totalmente preparados para afrontar el final de la vida durante la práctica clínica, posiblemente debido a escasas discusiones académicas y a insuficientes contenidos en la formación teórico-práctica. Los hombres con formación previa y que tuvieron contacto personal y académico con la muerte tuvieron una mayor percepción de preparación para afrontar el final de la vida, sin interferencia académica y de la religión.

An Incidental Finding Of A Persistent Sciatic Artery - Case Report And Literature Review.

Persistent sciatic artery is a rare anatomic variation due to the lack of regression during fetal development, associated sometimes with abnormalities of the iliofemoral arterial axis and predisposing the patients to aneurysm formation and thromboembolism, which can compromise the limb. In our department, we assisted a 59-year-old male with an acute limb ischemia as result of an incidental finding of a thrombosed persistent sciatic artery aneurysm.
