Fitting Degrees of Animal Models of Diarrhea-irritable Bowel Syndrome with Clinical Characteristics of Western Medicine and Traditional Chinese Medicine / 中国实验方剂学杂志

Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Correlation Between Expression of HIF-1α and Prognosis of Arsenic-containing Chinese Herbal Compound in Treatment of Myelodysplastic Syndrome / 中国实验方剂学杂志

ObjectiveMyelodysplastic syndromes （MDS） is a group of clonal hematopoietic stem cell disorders，and this study aims to investigate the expression of hypoxia-inducible factor-1α（HIF-1α） in the bone marrow cells of patients with MDS and its correlation with the clinical features of MDS，the therapeutic efficacy of arsenic-containing Chineseherbal compound，and the survival prognosis. MethodAccording to the inclusion and exclusion criteria，27 MDS patients treated with arsenic-containing Chinese herbal compound in the Department of Hematology，Xiyuan Hospital，China Academy of Chinese Medical Sciences from January 2022 to September 2022 were included，and their bone marrow samples were collected by myelotomy. HIF-1α expression level in bone marrow cells was detected by real-time polymerase chain reaction （PCR） to analyze its correlation with clinical features，and logistic and Cox regression was used to analyze the risk factors affecting the efficacy and prognostic survival of MDS patients. ResultThe HIF-1α mRNA expression level was lower in bone marrow cells of MDS patients than in healthy subjects. HIF-1α was positively correlated with the degree of myelodysplasia（r=0.384，P<0.05） and bone marrow granulocytic system%（G%）（r=0.560，P<0.01）. Logistic regression showed that HIF-1α was a risk factor for the prognosis in the follow-up of the efficacy of treatment（P<0.05）and Cox regression showed that HIF-1α was an independent factor affecting the survival prognosis of MDS patients ［odds ratio（OR）=398.968，95% confidence interval（CI）（1.281，116 858.743），P<0.05］. ConclusionThe level of HIF-1α expression in bone marrow cells of MDS patients was closely related to the degree of clinical myelodysplasia and G%，and HIF-1α was a risk factor for the efficacy for and survival prognosis of MDS patients.

Clinical Efficacy of TCM Multi-channel Intervention Plus Antagonist Regimen on Ovarian Function，TCM Syndromes and Natural Conception in Poor Ovarian Responders Undergoing IVF-ET / 中国实验方剂学杂志

ObjectiveTo objectively analyze the effects of traditional Chinese Medicine （TCM） multi-channel intervention on the ovarian function，TCM syndromes and natural conception of poor ovarian responders（kidney-Yin deficiency，liver depression and blood stasis pattern） who planned to receive another in vitro fertilization embryo transfer（IVF-ET）antagonist regimen. MethodThe 128 low-prognosis patients （kidney Yin deficiency，liver depression and blood stasis pattern） who attended the West China Second University Hospital， Sichuan University and the Hospital of Chengdu University of Traditional Chinese Medicine from August 2020 to February 2023 and met the inclusion criteria were selected，and then divided into the treatment group and the control group according to the random number table，with 64 patients in each group. The control group was treated with oral dehydroepiandrosterone（DHEA），while the treatment group was treated with multi-channel TCM（oral TCM decoction + auricular point sticking + Bushen Huoxue prescription through retention enema）. After 3 menstrual cycles，the relevant indicators for ovarian function evaluation，TCM syndrome scores and natural conception were collected from both groups. ResultCompared with the situation before treatment，the basal follicle stimulating hormone（bFSH），bFSH/basal luteinizing hormone（bLH），basal estradiol（bE2），antral follicle count（AFC），the number of oocytes obtained，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were improved after treatment（P<0.05，P<0.01）. For the control group， the bFSH/bLH and TCM syndrome scores were increased after treatment（P<0.05）， while the bFSH，bFSH/bLH，bE2，AFC，the number of oocytes obtained，the number of normal fertilization，and the number of superior embryos showed no significant difference after treatment. Compared with the control group after treatment，bFSH，bFSH/bLH，bE2，AFC，the number of normal fertilization，the number of superior embryos and TCM syndrome scores in the treatment group were better （P<0.05，P<0.01），while there was no significant difference in the number of oocytes obtained. After treatment，there were 3 cases of natural conception in the treatment group，while there were no natural conception in the control group. ConclusionFor patients with poor ovarian response and kidney Yin deficiency，liver depression and blood stasis pattern，multi-channel intervention of TCM plus the antagonist regimen can reduce bFSH，bFSH/bLH values，improve the levels of bE2，increase AFC，the number of oocytes obtained，the number of normal fertilization and the number of superior embryos，improve ovarian function，menstruation and TCM syndromes，improve their quality of life，and even enable some patients to get pregnant naturally before re-progression and improve their pregnancy outcome.

Evaluation of Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum

ABSTRACT Purpose: To assess Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum and correlate with ocular surface changes. Methods: This cross-sectional study evaluated patients with xeroderma pigmentosum. All patients underwent a comprehensive and standardized interview. The best-corrected visual acuity of each eye was determined. Detailed ophthalmic examination was conducted, including biomicroscopy examination of the ocular surface, Schirmer test type I, and meibography, and fundus examination was also performed when possible. Meibomian gland dysfunction was assessed by non-contact meibography using Oculus Keratograph® 5M (OCULUS Inc., Arlington, WA, USA). Saliva samples were collected using the Oragene DNA Self-collection kit (DNA Genotek Inc., Ottawa, Canada), and DNA was extracted as recommended by the manufacturer. Factors associated with abnormal meiboscores were assessed using generalized estimating equation models. Results: A total of 42 participants were enrolled, and 27 patients underwent meibography. The meiboscore was abnormal in the upper eyelid in 8 (29.6%) patients and in the lower eyelid in 17 (62.9%). The likelihood of having abnormal meiboscores in the lower eyelid was 16.3 times greater than that in the upper eyelid. In the final multivariate model, age (p=0.001), mutation profile (p=0.006), and presence of ocular surface malignant tumor (OSMT) (p=0.014) remained significant for abnormal meiboscores. For a 1-year increase in age, the likelihood of abnormal meiboscores increased by 12%. Eyes with OSMT were 58.8 times more likely to have abnormal meiboscores than eyes without ocular surface malignant tumor. Conclusion: In the final model, age, xeroderma pigmentosum profile, previous cancer, and clinical alterations on the eyelid correlated with a meiboscore of ≥2. Meibomian gland dysfunction was common in patients with xeroderma pigmentosum, mainly in the lower eyelid. The severity of Meibomian gland dysfunction increases with age and is associated with severe eyelid changes.

Effect of upper eyelid blepharoplasty on the ocular surface, tear film, and corneal microstructure

ABSTRACT Purpose: This study aimed to investigate the effect of upper eyelid blepharoplasty with the removal of the skin and a strip of orbicularis oculi muscle on the ocular surface, tear film, and dry eye-related symptoms. Methods: Twenty-two eyes of 22 consecutive patients operated by a single surgeon (21 females; mean age, 61 years; age range, 41-75 years) were included. All subjects completed the Ocular Surface Disease Index questionnaire, underwent in vivo confocal microscopy, tear film breakup time measurements, the Schirmer test with anesthesia, and fluorescein and lissamine green staining measurements before, 1 month, and 6 months after upper blepharoplasty alone with preseptal orbicularis excision. Results: A significant increase in Ocular Surface Disease Index, and corneal fluorescein and lissamine green staining and a significant decrease in tear film breakup time were observed after 1 month (p=0.003, p=0.004, p=0.029, and p=0.024 respectively) and 6 months (p=0.001 for all findings). No significant difference in the Schirmer test score was observed during the follow-up. None of the in vivo confocal microscopy parameters showed significant changes during the study. Conclusions: An increase in dry eye symptoms and a decrease in tear film stability along with ocular surface staining were observed in patients undergoing upper eyelid blepharoplasty.

Autoimmune encephalitis in a resource-limited public health setting: a case series analysis / Encefalite autoimune em um hospital universitário público: análise de uma série de casos

Abstract Background Autoimmune encephalitis (AE) consists of a group of acquired diseases that affect the central nervous system. A myriad of phenotypes may be present at the onset. Due to the heterogeneity of clinical presentations, it is difficult to achieve uniformity for the diagnostic and therapeutic processes and follow-up strategies. Objective To describe a series of patients diagnosed with AE in a resource-limited public hospital in southern Brazil and to analyze therapeutics and outcomes. Methods We retrospectively reviewed the electronic medical records of patients diagnosed with AE at the Hospital de Clínicas de Porto Alegre from 2014 to 2022. Data collected included clinical presentation, neuroimaging, cerebrospinal fluid testings, electroencephalogram, autoantibodies, treatments, outcomes, follow-up time, degree of neurological impairment, and mortality. Results Data from 17 patients were retrieved. Eleven cases were classified as definite AE and 6 as possible AE. Autoantibodies were identified in 9 patients. Timing for diagnosis was impacted by the high costs associated with autoantibody testing. Most patients became functionally dependent (82.4%) and most survivors remained with autoimmune-associated epilepsy (75%). Five patients died during hospitalization, and one after a 26-month of follow-up. Conclusion In this resource-limited hospital, patients with AE had a worse clinical outcome than that previously described in the literature. Development of epilepsy during follow-up and mortality were greater, whilst functional outcome was inferior. Autoantibody testing was initially denied in most patients, which impacted the definitive diagnosis and the use of second-line therapies.

Resumo Antecedentes A encefalite autoimune (EA) consiste em um grupo de doenças adquiridas que afetam o sistema nervoso central. Objetivo Descrever uma série de pacientes diagnosticados com EA em um contexto de atenção terciária à saúde com recursos limitados e analisar a terapêutica e os resultados. Métodos Revisamos retrospectivamente os prontuários eletrônicos de pacientes diagnosticados com EA no Hospital de Clínicas de Porto Alegre de 2014 a 2022. Os dados coletados incluíram apresentação clínica, neuroimagem, exames de líquido cefalorraquidiano, eletroencefalograma, autoanticorpos, tratamentos, resultados, tempo de acompanhamento, grau de comprometimento neurológico e mortalidade. Resultados Dados de 17 pacientes foram coletados. Onze casos foram classificados como EA definitivo e seis como EA possível. Autoanticorpos foram identificados em nove pacientes. O tempo para o diagnóstico foi afetado pelos altos custos associados ao teste de autoanticorpos. A maioria dos pacientes tornou-se funcionalmente dependente (82,4%), e a maioria dos sobreviventes permaneceu com epilepsia autoimune associada (75%). Cinco pacientes faleceram durante a internação, e um após 26 meses de seguimento. Conclusão No hospital em questão, os pacientes com EA tiveram um desfecho clínico pior do que o previamente descrito na literatura. O desenvolvimento de epilepsia durante o acompanhamento e a mortalidade foram maiores, enquanto o desfecho funcional foi inferior. Os testes de autoanticorpos foram inicialmente negados para a maioria dos pacientes, o que impactou o diagnóstico definitivo e o uso de terapias de segunda linha.

Tear film osmolarity variation between weeks in healthy and dry eye disease subjects / Variação semanal da osmolaridade do filme lacrimal em indivíduos saudáveis e com síndrome do olho seco

ABSTRACT Purpose: The possible variability in diagnostic test results is a statistical feature of dry eye disease patients. The clinician should consider tear film variations over time since the timing of tear film measurements is important for proper diagnosis. The purpose of the present study was to analyze the inter-week variation of osmolarity measurement in healthy and dry eye disease participants. Methods: Based on the Dry Eye Workshop II (DEWS-II) diagnostic methodology report criteria, a battery of tests (Ocular Surface Disease Index [OSDI] questionnaire, breakup time, and corneal staining) was administered to rule out the presence of dry eye disease. A total of 40 qualified volunteers were recruited into two groups: with only 20 healthy and 20 dry eye disease participants. The inter-week variation of osmolarity in the two groups was measured using a TearLab osmometer in two sessions one-week apart. The differences between the results were calculated. Results: There were no significant differences in osmolarity between the two sessions for either the healthy (paired t-test; p=0.085) or dry eye disease (paired t-test; p=0.093) participants. Moreover, there was no significant correlation between the means and differences in either session on healthy (Pearson correlation: r=0.020; p=0.935) or dry eye disease (Pearson correlation: r=-0.022; p=0.928) participants. In session 1, there was a significant difference in osmolarity values between groups (unpaired t-test; p=0.001), but no difference was found in session 2 (unpaired t-test; p=0.292). Conclusions: The present study discovered no inter-week variation in the tear film osmolarity of healthy and dry eye disease participants classified based on the DEWS-II criteria.

RESUMO Objetivo: A possível variabilidade nos resultados de testes diagnósticos é uma característica estatística dos pacientes com síndrome do olho seco. O médico deve considerar as variações do filme lacrimal ao longo do tempo, pois o momento em que o filme lacrimal é medido pode ser crítico para o diagnóstico adequado. O objetivo deste estudo foi analisar a variação semanal da osmolaridade do filme lacrimal em participantes saudáveis e em outros com síndrome do olho seco. Métodos: Com base nos critérios da metodologia de diagnóstico do relatório da Dry Eye Workshop II (DEWSII), foi aplicada uma bateria de testes (questionário do índice de doença da superfície ocular [OSDI], tempo de ruptura do filme lacrimal e coloração da córnea) para descartar a presença de síndrome do olho seco. Um total de 40 voluntários qualificados foi recrutado e distribuído em dois grupos de 20 participantes saudáveis e 20 participantes com síndrome do olho seco. A variação da osmolaridade entre semanas foi medida com um osmômetro TearLab em duas sessões com uma semana de intervalo nos dois grupos. As diferenças entre os resultados foram então calculadas. Resultados: Não foram encontradas diferenças significativas na osmolaridade entre as medidas obtidas nas duas sessões, nem no grupo de participantes saudáveis (teste de t pareado; p=0,085), nem no de participantes com síndrome do olho seco (teste de t pareado; p=0,093). Não foi detectada nenhuma correlação significativa entre as médias e diferenças entre as duas sessões entre participantes saudáveis (correlação de Pearson: r=0,020, p=0,935) e aqueles com síndrome do olho seco (correlação Pearson: r=-0,022, p=0,928). Foi encontrada uma diferença significativa nos valores de osmolaridade entre os dois grupos na primeira sessão (teste de t não pareado; p=0,001), mas nenhuma diferença foi encontrada na segunda sessão (teste de t não pareado; p=0,292). Conclusões: O presente estudo não encontrou variação entre semanas consecutivas na osmolaridade do filme lacrimal em participantes saudáveis e com síndrome do olho seco, classificados com base nos critérios do DEWSII.

Translation and validation of the 5-Item Dry Eye Questionnaire into Portuguese / Tradução e validação do questionário 5-Item Dry Eye Questionnaire para a língua portuguesa

ABSTRACT Purpose: Dry eye disease is a multifactorial disease that is very common in clinical ophthalmic practice. The use of validated dry eye questionnaires makes it possible to screen this disease in the general population and assess the prevalence of symptoms and frequency of diagnosis, allowing early and appropriate treatment for this condition. The 5-Item Dry Eye Questionnaire (DEQ-5) is a tool that is used to assess the frequency and intensity of ocular discomfort and dryness and the frequency of tearing, which has already been validated in English and Spanish, but not in Portuguese. The aim of this study is to translate and validate the DEQ-5 to Portuguese. Methods: The DEQ-5 was used, consisting of five simple and direct questions: two questions for ocular discomfort, two for ocular dryness, and one for tearing. The initial translation of the English version of the questionnaire into Portuguese was conducted by two Portuguese native-speaking translators, followed by an evaluation and compilation of a single version by an interdisciplinary committee of the translated versions. Furthermore, this version was translated back into English by two individuals whose first language was English, followed by the evaluation and comparison with the original version in English by the same interdisciplinary committee. Afterwards, the final version of the questionnaire was administered to 31 volunteers at two different times. Results: The interobserver reliability of the five questions ranged from 0.584-0.813, and the Pearson correlation from 0.755-0.935, with a p-value of <0.0001. Internal consistency was α=0.887. All questions had moderate to high agreement. Conclusions: The statistical analysis of the collected data found excellent concordance rates (moderate to high for all analyzed questions), allowing the use of the Portuguese version of DEQ-5 in research as a screening test for dry eye disease and tool used to monitor the symptoms.

RESUMO Ojetivos: O olho seco é uma doença multifatorial, muito comum na prática clínica oftalmológica. A utilização de questionários validados de sintomas de olho seco permite rastrear de maneira mais objetiva essa doença na população geral, avaliar a prevalência dos sintomas e frequência de diagnóstico, permitindo o tratamento precoce e adequado dessa condição. O 5-Item Dry Eye Questionnaire (DEQ-5) é um questionário em inglês que avalia a frequência e a intensidade do desconforto e ressecamento ocular e a frequência do lacrimejamento, já validado no inglês e espanhol, porém não no português até o presente momento. O objetivo deste estudo foi traduzir e validar o questionário DEQ-5 para a língua portuguesa. Métodos: Foi utilizado o questionário DEQ-5, composto por 5 perguntas simples e diretas - 2 relacionadas ao desconforto ocular, 2 ao ressecamento ocular e 1 ao lacrimejamento. Foi realizada a tradução inicial da versão em inglês para o português por dois tradutores de língua materna portuguesa, seguido de uma avaliação e compilação de uma versão única por um comitê interdisciplinar das versões traduzidas. Em seguida, tal versão foi traduzida de volta para o inglês por 2 indivíduos que possuíam o inglês como primeira língua, seguido de avaliação e comparação com a versão original em língua inglesa pelo mesmo comitê interdisciplinar. Após, a versão final do questionário foi aplicada em 31 voluntários em dois momentos differentes. Resultados: A confiabilidade interobservador das 5 perguntas variou de 0,584-0,813 e a correlação de Pearson de 0.755-0.935, sendo o p-valor <0,0001 em todas elas. A consistência interna foi α=0,887. Todas as perguntas apresentaram concordância de moderada a alta. Conclusões: A análise estatística dos dados coletados encontrou ótimos índices de concordância - moderada a alta para todas as questões analisadas -, permitindo o uso do DEQ-5 na língua portuguesa em pesquisas e também como forma de triagem para doença de olho seco e acompanhamento dos sintomas.

Evaluation of ocular surface in children with attention deficit hyperactivity disorder with respect to methylphenidate treatment / Avaliação da superfície ocular em crianças com transtorno de déficit de atenção com hiperatividade em relação ao tratamento com metilfenidato

ABSTRACT Purpose: This study aimed to screen the ocular surface of children with attention deficit hyperactivity disorder and identify the adverse effects of methylphenidate related to dry eye disease. Methods: This cross-sectional study included children with attention deficit hyperactivity disorder and healthy children (all aged 5-18 years). They were randomized into Group A (without methylphenidate treatment), Group B (with methylphenidate treatment), and Group C (healthy children). Tear film break-up time, Ocular Surface Disease Index questionnaire, tear meniscus height, tear meniscus area, and Schirmer test results were evaluated. Furthermore, symptom severity in attention deficit hyperactivity disorder was assessed by Turgay DSM-IV-based Child and Adolescent Behavioral Disorders Screening and Rating Scale and Conners Parent Rating Scale-48. Results: Groups A, B, and C consisted of 34, 40, and 60 individuals (n=34, 40, and 60 eyes; age=11.44 ± 2.79, 11.70 ± 2.83, and 11.96 ± 3.63 years, median age=12, 12, and 11.5 years), respectively. Tear film break-up time, Ocular Surface Disease Index, tear meniscus height, tear meniscus area, and Schirmer test results were not significantly different between Groups A and C (p=0.964, 0.336, 0.445, 0.439, and 0.759, respectively). However, Group B showed a significant decrease in tear film break-up time (10.50 ± 3.39 vs. 12.52 ± 2.46 s; p=0.005), tear meniscus height (307.40 ± 5.53 vs. 310.82 ± 7.30 µm; p=0.025), tear meniscus area (0.024 ± 0.0037 vs. 0.026 ± 0.0046 mm2; p=0.010) and Schirmer test (12.75 ± 3.96 vs. 15.41 ± 3.75 mm; p=0.004) results compared with Group A. Conclusion: Compared with healthy children, children with attention deficit hyperactivity disorder showed ocular surface parameters suggestive of dry eye disease despite taking methylphenidate. Thus, they require close ophthalmologic follow-up to prevent sight-threatening dry eye complications.

RESUMO Objetivos: Este estudo teve como objetivo examinar a superfície ocular de crianças com transtorno de déficit de atenção com hiperatividade e identificar os efeitos adversos do metilfenidato relacionados à síndrome do olho seco. Métodos: Este estudo transversal incluiu crianças com transtorno de déficit de atenção e hiperatividade e crianças saudáveis (todas entre 5-18 anos de idade). Elas foram randomizadas no Grupo A (sem tratamento com metilfenidato), Grupo B (com tratamento com metilfenidato) e Grupo C (crianças saudáveis). Foram avaliados o tempo de ruptura do filme lacrimal, questionário sobre Índice de Doenças de Superfície Ocular (IDSO), altura do menisco lacrimal, área do menisco lacrimal e os resultados do teste de Schirmer. Além disso, a gravidade dos sintomas no transtorno de déficit de atenção com hiperatividade foi avaliada usando a Turgay DSM-IV-based Child and Adolescent Behavioral Disorders Screening and Rating Scale com base na escala de Conners Parent Rating Scale-48. Resultados: Os Grupos A, B e C consistiram de 34, 40 e 60 indivíduos (n=34, 40 e 60 olhos; idade=11,44 ± 2,79, 11,70 ± 2,83 e 11,96 ± 3,63 anos, idade média=12, 123 e 11,5 anos), respectivamente. O tempo de ruptura do filme lacrimal, o Índice de Doença da Superfície Ocular, as altura do menisco lacrimal, a área do menisco lacrimal e o teste de Schirmer não foram significativamente diferentes entre os Grupo A e C (p=0,964, 0,336, 0,445, 0,439 e 0,759, respectivamente). Entretanto, o Grupo B mostrou uma redução significativa no tempo de ruptura do filme lacrimal (10,50 ± 3,39 vs 12,52 ± 2,46 seg; p=0,005), altura do menisco lacrimal (307,40 ± 5,53 vs 310,82 ± 7,30 µm; p= 0,025), área do menisco lacrimal (0,024 ± 0,0037 vs 0,026 ± 0,0046 mm2; p=0,010) e teste de Schirmer (12,75 ± 3,96 vs 15,41 ± 3,75 mm; p=0,004), resultados com0arados com o Grupo A. Conclusão: Em comparação com crianças saudáveis, crianças com transtorno de déficit de atenção com hiperatividade apresentaram parâmetros de superfície ocular sugestivos de olho seco, apesar do uso de metilfenidato. Assim, elas requerem um acompanhamento oftalmológico próximo para evitar complicações oculares de olho seco que ameaçam a visão.

Autologous serum eye drops diluted with 0.5% methylcellulose and 0.9% saline solution: a clinical comparative study / Colírio de soro autólogo diluído com metilcelulose 0,5% e solução salina 0,9%: um estudo clínico comparativo

ABSTRACT Purpose: This clinical study compared autologous serum eye drops diluted with 0.5% methylcellulose and 0.9% saline solution. The subjective criteria for symptom improvement and the objective clinical criteria for response to therapy were evaluated. Methods: This longitudinal prospective study enrolled 23 patients (42 eyes) with persistent epithelial defects or severe dry eye disease refractory to conventional therapy who had been using autologous serum 20% prepared with methylcellulose for > 6 months and started on autologous serum diluted in 0.9% saline solution. The control and intervention groups consisted of the same patients under alternate treatments. The subjective criteria for symptom relief were evaluated using the Salisbury Eye Evaluation Questionnaire. The objective clinical criteria were evaluated through a slit-lamp examination of the ocular surface, tear breakup time, corneal fluorescein staining, Schirmer's test, rose Bengal test, and tear meniscus height. These criteria were evaluated before the diluent was changed and after 30, 90, and 180 days. Results: In total, 42 eyes were analyzed before and after 6 months using autologous serum diluted with 0.9% saline. No significant differences were found in the subjective criteria, tear breakup time, tear meniscus, corneal fluorescein staining, or rose Bengal test. Schirmer's test scores significantly worsened at 30 and 90 days (p=0.008). No complications or adverse effects were observed. Conclusions: This study reinforces the use of autologous serum 20% as a successful treatment for severe dry eye disease resistant to conventional therapy. Autologous serum in 0.9% saline was not inferior to the methylcellulose formulation and is much more cost-effective.

RESUMO Objetivo: Este estudo comparou o colírio de soro au tólogo manipulado com metilcelulose a 0,5% com solução salina 0,9%. Critérios subjetivos de melhora dos sintomas e critérios clínicos objetivos para resposta à terapia foram avaliados. Métodos: Este estudo prospectivo longitudinal envolveu 23 pacientes (42 olhos) com defeitos epiteliais persistentes ou doença de olho seco grave refratária à terapia convencional que usavam colírio de soro autólogo 20% preparado com metilcelulose por mais de 6 meses e iniciaram soro autólogo diluído em solução salina 0,9%. Os grupos controle e intervenção consistiam dos mesmos pacientes sob tratamentos alternados. Os critérios subjetivos para o alívio dos sintomas foram avaliados usando o Salisbury Eye Evaluation Questionnaire. Os critérios objetivos foram avaliados por meio de exame em lâmpada de fenda incluindo: tempo de ruptura da lágrima, coloração da córnea com fluoresceína, teste de Schirmer, coloração com rosa bengala e altura do menisco lacrimal. Esses critérios foram avaliados antes da troca do diluente e após 30, 90 e 180 dias. Resultados: Um total de 42 olhos foram analisados antes e após 6 meses usando soro autólogo diluído com solução salina 0,9%. Nenhuma diferença significativa foi encontrada nos critérios subjetivos, tempo de ruptura da lágrima, menisco lacrimal, coloração com fluoresceína ou rosa bengala. Os resultados dos testes de Schirmer pioraram significativamente em 30 e 90 dias (p=0,008). Não foram observadas complicações ou efeitos adversos. Conclusões: Este estudo reforça o uso do colírio de soro autólogo 20% como um tratamento de sucesso para a doença do olho seco grave resistente à terapia convencional. O soro autólogo diluído em solução salina a 0,9% não foi inferior à formulação de metilcelulose.

Treating myofascial pain with dry needling: a systematic review for the best evidence-based practices in low back pain / Tratamento da dor miofascial com agulhamento a seco: uma revisão sistemática para as melhores práticas baseadas em evidências em lombalgia

Abstract Background Myofascial pain syndrome (MPS) is a common source of pain in primary care or pain clinics. There are many different ways to manage and treat MPS, such as physical exercise, trigger points massage, and dry needling. Objective The objective of this overview is to highlight and discuss the evidence-based treatment of myofascial pain by dry needling in patients with low back pain. Methods A systematic review was made based on meta-analysis (MA) and randomized controlled trials (RCTs) related to dry needling treatment for myofascial pain in patients with lumbar pain, published from 2000 to 2023. Results A total of 509 records were identified at first. Seventy were published before 2000, so they were excluded. From the remaining 439 studies, ninety-two were RCTs or MA, of which 86 additional studies were excluded for the following reasons: not related to dry needling treatment (n = 79), not published in English (n = 4), duplicated (n = 1), project protocol (n = 1), and not related to myofascial pain (n = 1). So, this review was based on 4 RCTs and two MA. These studies compared dry needling efficacy to other treatments, such as acupuncture, sham dry needling, laser therapy, physical therapy, local anesthetic injection, ischemic compression, and neuroscience education. Despite outcomes and follow-up period varied between them, they showed that dry needling can decrease post-intervention pain intensity and pain disability. Conclusion Dry needling is an effective procedure for the treatment of myofascial pain in patients with acute and chronic low back pain. Further high-quality studies are needed to clarify the long-term outcomes.

Resumo Antecedentes A síndrome dolorosa miofascial (SDM) é uma fonte comum de dor em centros primários de atenção à saúde ou nas clínicas de dor. Existem muitas formas diferentes de manejar e tratar a SDM, como o exercício físico, a massagem dos pontos de gatilho e o agulhamento a seco. Objetivo O objetivo desta revisão é destacar e discutir o tratamento baseado em evidências da dor miofascial por agulhamento a seco em doentes com dor lombar. Métodos Foi realizada uma revisão sistemática baseada em metanálises (MA) e ensaios clínicos randomizados (RCTs) relacionados ao tratamento da dor miofascial com agulhamento a seco em pacientes com dor lombar, publicados de 2000 a 2023. Resultados Foram identificados, inicialmente, um total de 509 registos. Setenta deles, publicados antes de 2000, foram excluídos. Dos 439 estudos restantes, 92 eram RCTs ou MA, dos quais 86 foram excluídos pelas seguintes razões: não relacionados a tratamento com agulhamento a seco (n = 79), não publicados em inglês (n = 4), duplicados (n = 1), protocolo de projeto (n = 1) e não relacionados com dor miofascial (n = 1). Assim, esta revisão baseou-se em quatro RCTs e duas MA. Esses estudos compararam a eficácia do agulhamento seco com outros tratamentos, tais como acupuntura, agulhamento a seco "sham", terapia com laser, fisioterapia, injeção de anestésico local, compressão isquêmica e educação em neurociências. Apesar de os resultados e o período de seguimento variarem entre os estudos, os estudos demonstram que o agulhamento a seco pode diminuir a intensidade da dor pós-intervenção e a incapacidade relacionada à dor. Conclusão O agulhamento a seco é um procedimento eficaz para o tratamento da dor miofascial em pacientes com dor lombar aguda e crônica. Mais estudos são necessários para esclarecer sua eficácia a longo prazo.

Clínica, auxología y calidad de vida en cincuenta niños, niñas y adolescentes con síndromes de sobrecrecimiento corporal segmentario de un único centro / Clinical and auxological characteristics and quality of life of 50 children and adolescents with segmental overgrowth syndromes at a single center

Introducción. Los síndromes de sobrecrecimiento corporal segmentario son un grupo de enfermedades poco frecuentes caracterizadas por exceso de crecimiento en una o más partes del cuerpo relacionadas, en su mayoría, con mutaciones en mosaico en la vía de señalización AKT/PI3K/mTOR y RAS-MAPK. Nuestro objetivo fue analizar las características clínicas y auxológicas, y la calidad de vida relacionada a salud (CVRS) en este grupo de pacientes en un hospital de tercer nivel de atención. Población y métodos. Estudio transversal de una cohorte en seguimiento. Se analizaron edad, sexo, datos sociodemográficos, mediciones antropométricas del segmento afectado y del contralateral, complicaciones, tratamiento, calidad de vida (PedsQL4.0) y dolor. Se calcularon medidas centrales y de dispersión. Se realizó análisis univariado entre calidad de vida y variables incluidas. Resultados. Se incluyeron 50 pacientes, 29 varones. Mediana de edad 9,95 (r 1,44-17,81) años. El diagnóstico más frecuente fue síndrome de sobrecrecimiento relacionado a PIK3CA (PROS) (37/50). Mediana de número de segmentos afectados 2 (r: 1-7) por niño. Cuarenta casos presentaron malformación vascular; 20, capilar. El dolor (24/50) fue la complicación más frecuente. Treinta y un pacientes mostraron asimetría de longitud de miembros inferiores, < 5 cm. La estatura se ubicó entre los centilos 50 y 97 en la mayoría de los niños. Menor CVRS se observó en mujeres, en pacientes con malformación vascular compleja y necesidades básicas insatisfechas (NBI). Conclusiones. PROS fue el diagnóstico más frecuente. El dolor fue una complicación frecuente. La CVRS fue menor en mujeres, pacientes con malformación vascular combinada y NBI.

Introduction. Segmental overgrowth syndromes are a group of rare diseases characterized by overgrowth in one or more parts of the body, mostly related to mosaic mutations in the AKT/PI3K/mTOR and RASMAPK signaling pathway. Our objective was to analyze the clinical and auxological characteristics and health-related quality of life (HRQoL) in this group of patients at a tertiary care hospital. Population and methods. Cross-sectional study of a follow-up cohort. Age, sex, sociodemographic data, anthropometric measurements of the affected and contralateral segments, complications, treatment, quality of life (PedsQL 4.0), and pain were analyzed. Central and dispersion measures were estimated. A univariate analysis between the quality of life and study variables was done. Results. A total of 50 patients were included; 29 were males. Median age: 9.95 (r: 1.44­17.81) years. The most common diagnosis was PIK3CA-related overgrowth spectrum (PROS) (37/50). The median number of affected segments was 2 (r: 1­7) per patient. Vascular malformations were observed in 40, and capillary malformations, in 20 patients. Pain was the most common complication (24/50). An asymmetry of the lower extremities of < 5 cm was observed in 31 patients. In most children, height was between the 50th and 97th percentiles. A lower HRQoL was observed among girls, patients with complex vascular malformations, and those with unmet basic needs (UBNs). Conclusions. PROS was the most common diagnosis. Pain was the most common complication. HRQoL was lower among girls, patients with combined vascular malformations, and those with UBNs.

Efficacy of ultrasound-guided infiltration with levobupivacaine and triamcinolone for myofascial pain syndrome of the quadratus lumborum: a retrospective observational study

Abstract Introduction and objectives: Myofascial Pain Syndrome (MPS) of the Quadratus Lumborum muscle (QL) is a frequent cause of chronic low back pain. With this study, we aimed to assess the efficacy of ultrasound-guided infiltration with 0.25% levobupivacaine and 40 mg triamcinolone for MPS of the QL. Methods: Observational and retrospective study of participants submitted to ultrasound-guided infiltration of the QL muscle from January 1, 2015 to June 31, 2019. Pain intensity was assessed using the five-point pain Numeric Rating Scale (NRS): pre-intervention, at 72 hours, 1 month, 3 months and 6 months post-intervention. Additional data collected were demographic characteristics, opioid consumption, and adverse effects. Results: We assessed 90 participants with mean age of 55.2 years. Sixty-eight percent of participants were female. Compared to the pre-intervention assessment, there was an improvement in pain at 72 hours (Mean Difference [MD = 3.085]; 95% CI: 2.200-3.970, p < 0.05), at the 1st month (MD = 2.644; 95% CI: 1.667-3.621, p < 0.05), at the 3rdmonth (MD = 2.017; 95% CI: 0.202-2.729, p < 0.05) and at the 6th month (MD = 1.339; 95% CI 0.378-2.300, p < 0.05), post-intervention. No statistically significant differences in opioid consumption were observed. No adverse effects associated with the technique were reported. Conclusions: Ultrasound-guided infiltration of the QL muscle is a safe and effective procedure for the treatment of pain in the QL MPS within 6 months post-intervention.

ABSTRACT Background: Cardiogenic shock (CS) is a life-threatening complication of acute myocardial infarction (AMI) and constitutes one of the leading causes of death. Objective: The aim of this study was to investigate the clinical characteristics, treatment strategies, hospital outcome and 30-day mortality of CS in Argentina. Methods: We conducted a prospective, and multicenter registry of patients with acute myocardial infarction (AMI) with and without ST-segment elevation complicated with CS that were hospitalized in 23 centers in Argentina for 14 months (between August 1, 2021, and September 30, 2022). Results: The cohort was made up of 114 patients; median age was 64 years (58-73) and 72% were women; 76.3% corresponded to ST-segment elevation AMI, 12.3% to non-ST-segment elevation AMI, 7% had right ventricular infarction and 4.4% had mechanical complications. In 66.6% of cases CS was present on admission. Revascularization: 91.1%, use of inotropic agents: 98.2%, mechanical ventilation: 59.6%, Swan-Ganz catheter: 33.3%, intra-aortic balloon pump: 30.1%. Overall in-hospital mortality was 60.5%, with no differences between AMI with or without ST-segment elevation, and was 62.6% at 30 days. Conclusion: Morbidity and mortality of CS are high despite the high rate of reperfusion therapy used.

Epilepsias generalizadas idiopáticas / Idiopathic generalized epilepsies

Resumen Las epilepsias generalizadas idiopáticas (EGI) son un grupo de epilepsias generalizadas edad de pendientes, subgrupo de las Epilepsias genéticas generalizadas(EGG), con hallazgos electro-clínicos característicos y herencia poligénica. Las EGI inclu yen las cuatro epilepsias generalizadas clásicas más comunes de las EGG: la epilepsia de ausencias de la infancia (EAI), epilepsia de ausencias juveniles (EAJ), epilepsia mioclónica juvenil (EMJ) y la epilepsia con crisis tónico clónicas generalizadas. Clínicamente caracterizadas por la presencia de una o una com binación de crisis de ausencias, mioclonías, tónica-clónicas omioclónica-tónica-clónicas con patrón elec troencefalográfico de punta onda lenta de 2.5 a 6cps y activación con la hiperventilación y fotoestimula ción, Sobresalen de las EGG por compartir atributos particulares como el buen pronóstico con control frecuente de las crisis, la no evolución a encefalopa tías epilépticas, frecuente superposición clínica entre las tres primeras, pudiendo evolucionar entre ellas; la probabilidad y edad de remisión varía en cada una.Más del 80% se controlan adecuadamente con medicamentos anticrisis de amplio espectro como el ácido valproico y pueden empeorar con bloqueadores de sodio o gabaérgicos. Si bien los pacientes son previamente sanos con neurodesarrollo normal, frecuentemente se asocian con trastornos del ánimo, déficit de atención e hiperactividad (TDAH) y problemas del aprendizaje pero no presentan déficit cognitivo. El reconocimiento de este grupo de EGI es importan te para el uso adecuado del recurso, evitando estudios innecesarios, adecuada orientación del pronóstico y un tratamiento óptimo.

Abstract Idiopathic generalized epilepsies (IGE) is a group of epilepsies age-dependent, a subgroup of EGG genetic generalized epilepsies, with electro-clinical features and polygenic inheritance. Four syndromes comprising the IGEs: childhood absence epilepsy (CAD), juvenile absence epilepsy (JAE), juvenile myoclonic epilepsy (JME), and generalized tonic-clonic seizures epilepsy. Clinically characterized by the presence of one or a combination of absence seizures, myoclonus, tonic-clonic, or myoclonic-tonic-clonic with common electroencephalographic pat terns of 2.5-5.5 Hz generalized spike-wave and activated by hyperventilation or photic stimulation. They generally have a good prognosis for seizure control, not evolve to an epileptic encephalopathy. Frequent clinical overlap between the first three, being able to evolve between them; the probability and age of remission varies in each one. About 80% responding to broad-spectrum anti-seizure drugs such as valproic acid, may worsen with sodium or GABAergic blockers. Development is typically normal; however, they are frequently associated with mood disorders, attention-deficit/hyperactivity disorder (ADHD), and learning dis abilities, but do not have cognitive deficits. The recognition of this group of EGI is important for the adequate use of the resources, avoiding unnecessary studies, adequate orientation of the prognosis and an optimal treatment.

Sjogren-Larsson syndrome brain volumetric reductions demonstrated with an automated software / Reduções volumétricas cerebrais da síndrome de Sjogren-Larsson demonstradas com um software automatizado

Abstract Background Sjogren-Larsson syndrome (SLS) is a neurocutaneous disease with an autosomal recessive inheritance, caused by mutations in the gene that encodes fatty aldehyde dehydrogenase (ALDH3A2), clinically characterized by ichthyosis, spastic diplegia, and cognitive impairment. Brain imaging plays an essential role in the diagnosis, demonstrating a nonspecific leukoencephalopathy. Data regarding brain atrophy and grey matter involvement is scarce and discordant. Objective We performed a volumetric analysis of the brain of two siblings with SLS with the aim of detecting deep grey matter nuclei, cerebellar grey matter, and brainstem volume reduction in these patients. Methods Volume data obtained from the brain magnetic resonance imaging (MRI) of the two patients using an automated segmentation software (Freesurfer) was compared with the volumes of a healthy control group. Results Statistically significant volume reduction was found in the cerebellum cortex, the brainstem, the thalamus, and the pallidum nuclei. Conclusion Volume reduction in grey matter leads to the hypothesis that SLS is not a pure leukoencephalopathy. Grey matter structures affected in the present study suggest a dysfunction more prominent in the thalamic motor pathways.

Resumo Antecedentes A Síndrome de Sjogren-Larsson (SSL) é uma doença neurocutânea de herança autossômica recessiva, causada por mutações no gene que codifica a aldeído graxo desidrogenase (ALDH3A2), caracterizada clinicamente por ictiose, diplegia espástica e comprometimento cognitivo. A imagiologia cerebral desempenha um papel essencial no diagnóstico, demonstrando uma leucoencefalopatia inespecífica. Dados sobre atrofia cerebral e envolvimento da substância cinzenta são escassos e discordantes. Objetivo Realizamos uma análise volumétrica do cérebro de dois irmãos com SLS com o objetivo de detectar núcleos profundos de substância cinzenta, substância cerebral cinzenta e redução do volume do tronco encefálico nestes pacientes. Métodos Os dados de volume obtidos da ressonância magnética (RM) cerebral dos dois pacientes usando um software de segmentação automática (Freesurfer) foram comparados com os volumes de um grupo controle saudável. Resultados Redução de volume estatisticamente significativa foi encontrada no córtex do cerebelo, no tronco cerebral, no tálamo e nos núcleos pálidos. Conclusão A redução do volume da substância cinzenta leva à hipótese de que a SSL não é uma leucoencefalopatia pura. As estruturas da substância cinzenta afetadas no presente estudo sugerem uma disfunção mais proeminente nas vias motoras talâmicas.

Recientemente se han reportado eventos adversos relacionados a la inmunoterapia. La to xicidad neurológica es poco frecuente. Se presenta el caso de un paciente con encefalitis relacionada con inhibido res del punto de control inmunitario.

Abstract Immune checkpoint inhibitors have been shown to improve the prognosis of multiple oncological diseases. Recently, adverse events related to immunotherapy have been reported. Neurologic toxicity is infrequent. We pre sent the case of a patient with encephalitis associated to immune checkpoint inhibitors.

Linfoma de Hodgkin: neuronopatía sensitiva y autonómica como manifestación paraneoplásica / Hodgkin's lymphoma: sensitive and autonomic neuropa thy as a paraneoplastic manifestation

Resumen El linfoma de Hodgkin (LH) comprende un grupo heterogéneo de neoplasias linfoides cuyo origen radica en linfocitos B. Las manifestaciones neurológicas de dicha enfermedad son infrecuentes, pudiendo tener su origen por invasión directa de las células neoplásicas en el sistema nervioso, o indirectamente, a través de síndromes paraneoplásicos o como complicación del tratamiento. Dentro de los síndromes neurológicos paraneoplásicos que afectan a pacientes con LH, la degeneración cerebelosa paraneoplásica es la más frecuente. Otros reportados con menor frecuencia en series de casos o casos aislados incluyen encefalitis límbica, neuronopatía sensitiva, motora y autonómica. Estos pueden ser la manifestación inicial de la enfer medad neoplásica, y la falta de conocimiento de dicha asociación puede retrasar el diagnóstico, con inicio tardío del tratamiento y peor pronóstico. Reportamos el caso de una mujer con LH que presentó al inicio de su enfermedad neuronopatía sensitiva y autonómica como manifestaciones neurológicas paraneoplásicas. Una vez iniciado el tratamiento específico para su lin foma, la neuronopatía autonómica tuvo resolución casi completa a diferencia de la neuronopatía sensitiva, la cual demostró escasa recuperación.

Abstract Hodgkin lymphoma (HL) comprises a heterogeneous group of lymphoid neoplasms whose origin lies in B lym phocytes. The neurological manifestations of this pathol ogy are infrequent, and may arise from direct invasion of neoplastic cells to the nervous system, or indirectly, through paraneoplastic syndromes or as a complication of treatment. Among the neurological paraneoplastic syndromes that affect patients with HL, paraneoplastic cerebellar degeneration is the most common. Other few cases include limbic encephalitis, sensory, motor, and autonomic neuronopathy. These syndromes can be the initial manifestation of neoplastic disease, and the lack of information regarding this association can lead to a delay in diagnosis and consequently in the initiation of therapy worsening the prognosis. We report the case of a woman with HL who presented sensory and autonomic neuronopathy at the onset of her disease as paraneo plastic neurological manifestations. After the initiation of the specific treatment for the lymphoma, the autonomic neuronopathy had almost complete resolution, unlike the sensory neuronopathy, which showed limited recovery.

Administración subcutánea de levotiroxina en hipotiroidismo refractario / Subcutaneous administration of levothyroxine in refrac tory hypothyroidism

Resumen El hipotiroidismo generalmente se puede tratar de manera efectiva con levotiroxina (LT-4) oral. Sin em bargo, el hipotiroidismo refractario al tratamiento con LT-4 es una condición clínica frecuente. Entre las causas se encuentra la falta de adherencia, interacciones con alimentos u otros medicamentos y enfermedades gas trointestinales, como enfermedad inflamatoria intestinal y síndromes de intestino corto. El aumento de la dosis oral de LT-4 no siempre es eficaz en estos escenarios. Por lo tanto, pueden ser necesarias otras vías de administración. En este reporte, evaluamos modalidades alternativas de tratamiento para el hipotiroidismo re fractario y presentamos dos pacientes con malabsorción intestinal tratadas con éxito mediante la administración subcutánea de LT-4.

Abstract Hypothyroidism can usually be treated effectively with oral levothyroxine (LT-4) supplementation. However, hypothyroidism refractory to treatment with LT-4 is a common clinical condition. Causes include poor com pliance, interactions with food or other medications, and gastrointestinal diseases, such as inflammatory bowel disease and short bowel syndromes. Increasing the oral dose of LT-4 is not always effective in these scenarios. Therefore, other routes of administration may be neces sary. In this report, we evaluate alternative treatment modalities for refractory hypothyroidism and present two patients with intestinal malabsorption successfully treated by subcutaneous administration of LT-4.

Impacto econômico da implementação de políticas públicas para distúrbios de sono no Brasil: uma revisão integrativa / Economic impact of the implementation of public policies for sleep disorders in Brazil: an integrative review

Objetivo: Identificar estudos sobre políticas públicas, ações de saúde e análises econômicas relacionados aos distúrbios de sono no Brasil e discutir os seus resultados para o sistema de saúde, gestores de políticas públicas e a sociedade. Métodos: Revisão integrativa da literatura nas bases de dados Lilacs (via BVS), SciELO e PubMed (via Medline), incluindo estudos publicados nos idiomas português, inglês e espanhol, entre os anos de 1960-2023; foram excluídos estudos que não apresentaram a perspectiva brasileira ou aqueles cuja versão integral não estava disponível (seja gratuitamente ou na versão paga). Resultados: A busca retornou 536 resultados, dos quais apenas dois atendiam aos critérios de inclusão e mais cinco trabalhos foram incluídos manualmente, após consulta com especialistas de sono (todos abordaram apneia obstrutiva do sono, sendo: um relato sobre alteração na legislação de trânsito focada em prevenção de acidentes por sonolência excessiva; uma revisão de escopo sobre análises de custo-efetividade do tratamento da doença com uso de CPAP; dois relatos sobre linha de cuidado em um município e outros três em Secretarias Estaduais de Saúde). Conclusões: A revisão integrativa encontrou poucas evidências acerca do tema e aponta para a necessidade de futuros estudos que visem a suprir essa lacuna científica e de que seja necessário o desenvolvimento de futura linha de cuidado que amplie o acesso ao tratamento de doenças do sono no Sistema Único de Saúde.

Objective: To identify studies on public policies, health actions, and economic analyses related to sleep disorders in Brazil and discuss their results for public policy managers and society. Methods: Integrative literature review using Lilacs (via BVS), SciELO, and PubMed (via Medline) databases, including studies published in Portuguese, English, and Spanish languages, between years of 1960-2023; studies that did not present the Brazilian perspective or whose full version was not available were excluded (free or paid version). Results: The search returned 536 results, of which only two met the inclusion criteria, and five more studies were included manually after consulting sleep experts (all addressing obstructive sleep apnea, namely: a report on changes in traffic legislation focused on preventing accidents caused by excessive sleepiness; a scoping review on cost-effectiveness analysis of CPAP for sleep apnea treatment; two reports on care lines in one municipality and another three in State Secretariats). Conclusions: The integrative review found few evidences on the topic and points to the need for future studies aimed at filling this scientific gap and the development of a care line that expands access to sleep disorder treatment in Brazilian Public Health System.
