Acquired immunodeficiency syndrome is an infectious disease caused by human immunodeficiency virus (HIV). Pharmacological antiretroviral therapy, along with therapeutic monitoring of drug plasma concentrations, facilitates adequate and effective follow-up in each patient. Our main objective was to develop and validate a high-performance liquid chromatography with ultraviolet detector (HPLC-UV) bioanalytical method for the simultaneous quantification of plasma concentrations of three commonly used antiretrovirals in Colombia: efavirenz, lopinavir, and ritonavir. This method is intended for therapeutic drug monitoring in persons living with HIV locally or in developing countries. The method is selective, specific, accurate, precise, and stable over the concentration range of 250 and 20,000 ng mL -1 for the drugs. It was successfully applied to measure the plasma levels of efavirenz, lopinavir, and ritonavir in HIV patients, which ranged from 251.0 ± 10.4 to 7186.2 ± 10.2, 8188.2 ± 5.9 to 15,312.5 ± 6.6, and 246.1 ± 6.5 to 1189.0 ± 6.4 ng mL-1, respectively.

RESUMO Objetivo: Descrever as características epidemiológicas de pacientes pediátricos com doença falciforme (DF) e avaliar o uso de plantas medicinais concomitantemente ao tratamento medicamentoso. Métodos: Realizou-se revisão de prontuários de pacientes pediátricos de uma instituição pública com nível de atendimento terciário; o critério de seleção foi ser criança ou adolescente com DF em acompanhamento pediátrico neste ambulatório. Nos prontuários dos pacientes selecionados foi procurado o registro do uso de plantas com finalidades medicinais. Resultados: Foram revisados 154 prontuários (100% dos pacientes ativos desse ambulatório): 99 crianças e 55 adolescentes. O genótipo predominante foi SS (58,4%), seguido do SC (29,2%). O uso de ao menos uma medicação para a DF foi relatada em 95,5% dos prontuários. Em 70,1% dos prontuários havia o relato do uso de plantas medicinais, em 276 citações, sendo 64 plantas citadas ao todo; destas, seis espécies foram citadas para o tratamento da doença de base (DF), sendo “ora-pro-nobis” (Pereskia aculeata) a principal. Das 276 citações de plantas medicinais nos prontuários, 60,5% incluíram o uso de plantas medicinais em sintomas gripais e/ou COVID-19 (tanto prevenção quanto tratamento), sendo relatadas 35 para este uso, exclusivamente ou não. Essa foi a principal finalidade de uso encontrada nos prontuários dos pacientes, seguida do uso para sintomas de dor (14,2% das citações). Conclusões: Notou-se que a maioria dos pacientes avaliados faz uso da medicina convencional, aliada à tradicional/ complementar/ alternativa, o que leva à necessidade de mais estudos nessas áreas, especialmente na pediatria, visando principalmente à segurança do paciente.

ABSTRACT Objective: The aim of this study was to describe the epidemiological characteristics of pediatric patients with sickle cell disease (SCD) and evaluate the use of medicinal plants in these patients concomitantly with their drug treatment. Methods: This is a review of the medical records of pediatric patients at a public institution with tertiary care. The selection criterion was to be a child or adolescent with SCD undergoing pediatric follow-up at this outpatient clinic. In the medical records of the patients selected, records of the use of plants for medicinal purposes were sought. Results: In total, 154 records (100% of total active patients followed in this clinic) were reviewed: 99 children and 55 adolescents. The predominant genotype was SS (58.4%), followed by SC (29.2%). The use of at least one medication for SCD was reported in 95.5% of the medical records. The use of medicinal plants was reported by 70.1% of patients, with 276 citations in the medical records referring to 64 different types of plants. Six plants were used for the treatment of SCD, the main one being Lemonvine/Ora-pro-nóbis (Pereskia aculeata). The use of medicinal plants was reported for flu-like symptoms and/or COVID-19 (both for prevention and treatment) by 60.5% of the citations, with 35 different plants reported for this use, exclusively or not. This use was followed by pain symptoms (14.2% of citations). Conclusions: The majority of patients in this study use both conventional and traditional/complementary/alternative medicine, highlighting the need for more studies in the area, with a special focus on patient safety.

APPLICATION OF MASS SPECTROMETRY WITH PAPER SPRAY IONIZATION AND THE OPLS-DA CHEMOMETRIC METHOD FOR THE DIAGNOSIS OF PROSTATE CANCER BY ANALYSIS OF URINE SAMPLES. In this study, paper spray ionization mass spectrometry (PSI-MS) allied to orthogonal projections on the latent structure-discrimination analysis (OPLS-DA) was employed to differentiate urine samples from patients with prostate cancer and control individuals (without prostate cancer). The parameters of sensitivity, specificity, efficiency and Matthew’s correlation coefficient determined to analyze the efficiency and quality of the OPLS-DA model obtained a value equal to 1, which means, respectively, that the model has a good performance to correctly classify true positive samples and true negatives. These results showed 100% correct classification of the samples from the training and test set, demonstrating a high efficiency of the OPLS-DA model when classifying all samples considered as belonging to the class of interest (urine from control patient) into class 1 and all samples considered as belonging to the non-interest class (urine from patients with prostate cancer) in class 0. This efficiency resulting from the application of this model suggests that the PSI-MS combined to OPLS-DA is a promisor approach for a rapid diagnosis of prostate cancer, via chemical fingerprints of urine samples.

ABSTRACT Purpose: To evaluate the predictive value of initial intraocular pressure difference of the detached and fellow eyes of patients with complex rhegmatogenous retinal detachment on postoperative persistent ocular hypotony. Methods: This retrospective observational study included 538 eyes of 538 unilateral complex rhegmatogenous retinal detachment patients with a proliferative vitreoretinopathy grade of C-1 or higher, treated with silicone oil endotamponade following pars plana vitrectomy. The patients were divided into Group A (patients having silicone oil removal without ocular hypotony; n=504) and Group B (patients with persistent ocular hypotony following silicone oil removal [n=8, 23.5%] and with retained silicone oil [n=26, 76.5%] due to the risk of persistent ocular hypotony; total n=34). Ocular hypotony was defined as an intraocular pressure of <6 mmHg on two or more occasions. Patients’ demographics, including age, sex, and follow-up time, and ocular characteristics, including ocular surgical and trauma history, initial and final best-corrected visual acuity, intraocular pressure and initial intraocular pressure difference of the detached and fellow eyes, and anatomical success rates and postoperative complications, were retrospectively collected from the electronic patient files. Results: The initial intraocular pressure was significantly lower in the detached eyes of Group B than in Group A (8.3 ± 3.5 vs. 12.9 ± 3.3, p<0.001). Also, the initial intraocular pressure difference was significantly higher in Group B than in Group A (8.9 ± 3.2 vs. 2.2 ± 2.7mmHg, p<0.001). The receiver operating characteristic curve analysis showed that the cutoff value of the initial intraocular pressure difference was 7.5mmHg for the risk of persistent ocular hypotony. The most influential factors on postoperative persistent ocular hypotony in the binary logistic regression analysis were the initial intraocular pressure difference and the need for a retinectomy. Conclusion: In eyes with complex rhegmatogenous retinal detachment treated with pars plana vitrectomy and silicone oil tamponade, the initial intraocular pressure difference could be of value in predicting postoperative persistent ocular hypotony and could guide surgeons on the decision of silicone oil removal.

ABSTRACT We present the case of a 37-year-old woman who underwent bilateral penetrating keratoplasty for congenital hereditary endothelial dystrophy at the age of 10 years. Over the subsequent 27 years, the patient’s vision slowly deteriorated. Our examination revealed decompensation of the right corneal graft. We addressed this with regraft surgery. We then learned that the patient had been suffering from progressive hearing loss since adolescence. Tonal audiometry revealed hearing per ceptive deafness of 25 dB, which was more prominent in the left ear. Because the patterns of progressive sensorineural hearing loss and congenital hereditary endothelial dystrophy have both been linked to the same gene, slc4a11, we tested our patient for mutations in this gene. The test was positive for a heterozygous slc4a11 gene fifth exon mutation on chromosome 20p13-p12, which causes a frameshift. A combined clinical and genetic evaluation confirmed a diagnosis of Harboyan syndrome. After the genetic diagnosis of the disease, she was evaluated for the need for a hearing aid due to her hearing loss. The patient was also informed about genetic counseling. 37yearold yearold 37 year old 1 years 2 patients s deteriorated graft surgery adolescence dB ear slca slc slc4a1 20p13p12, 20p13p12 pp 20p13 p12, p12 p 20p13-p12 frameshift syndrome disease counseling 3 slc4a 20p13p1 20p1 p1 20p13-p1 20p13p 20p 20p13-p

ABSTRACT Langerhans cell histiocytosis comprises a heterogeneous range of clinical manifestations secondary to clonal proliferation of histiocytes, characterized by the accumulation of these cells in various organs and tissues. The ophthalmological component commonly involved is the orbit. Herein, we report a rare case of Langerhans cell histiocytosis with eyelid involvement, which resulted in severe ocular surface complications, which subsequently significantly impacted the patient’s quality of life. This case report highlights the fact that despite being rare, Langerhans cell histiocytosis should be included in the differential diagnosis of eyelid lesions. Furthermore, a multidisciplinary approach with a systemic overview is crucial for managing the ocular complications. histiocytes tissues orbit Herein involvement complications patients patient s life lesions Furthermore

ABSTRACT Aging and face sagging have many causes, and various techniques are used for treatment, including noninvasive procedures, such as focused ultrasound, which uses the principle of collagen regeneration by coagulative necrosis of the dermis layers using radiofrequency, but this procedure has complications. We reported a case of a 54-year-old female patient who complained of poor visual acuity in her right eye three days after a focused ultrasound facial aesthetic procedure, with the best visual acuity of 20/60. Biomicroscopy of the right eye revealed an acute cataract with three points of fibrosis extending from the posterior to the anterior capsule. The patient underwent phacoemulsification surgery with visual rehabilitation and improved vision of 20/20. We hypothesized that the occurrence of acute cataract was related to the inappropriate use of focused ultrasound. causes treatment procedures radiofrequency complications 54yearold yearold 54 year old 2060 20 60 20/60 capsule 2020 20/20 5 206 2 6 20/6 202 20/2 20/

ABSTRACT Purpose: This study aimed to evaluate the perception and degree of satisfaction of blind individuals regarding an electronic cane prototype with a wearable haptic interface. Methods: Two scenarios with different obstacles were created to conduct tests with the canes (the user’s cane and the prototype one). The perception and satisfaction of participants regarding the electronic cane were assessed using a questionnaire, the number of collisions during the tests, and the time each individual took to complete the course in each scenario. Results: Ten blind individuals who used the white cane participated in this study. Eight were males, and two were females. Their age ranged from 23 to 43 (average 32.3 ± 7.13 years and median 32 years). There was a tendency for fewer collisions with ground obstacles when the electronic cane was used than when the white cane was used. However, there was no statistically significant difference between the number of collisions and the course completion time in each scenario with either canes tested. Conclusion: Overall, the perception and satisfaction of individuals regarding the prototype used were positive.

ABSTRACT Purpose: Although Brazil has a high prevalence of retinoblastoma, there is a lack of epidemiological data on the disease. Thus, in this study, we aimed to evaluate the epidemiological profile of patients diagnosed with retinoblastoma in the ophthalmology department of a pediatric tertiary referral hospital in Ceara, Brazil. Methods: A descriptive and cross-sectional study was conducted by retrospectively analyzing the clinical and socioeconomic data from the medical records of pediatric patients followed-up at the hospital between 2007 and 2021. Retinoblastoma was diagnosed on the basis of a fundoscopic or histopathologic examination. Results: The data of 105 patients were included in the study, and the mean patient age at the time of diagnosis was 1.7 years. Most of the patients were women (50.5%) and hailed from rural areas (57.4%), which was associated with a higher tumor stage. Of the 150 patients, 57.1% initially presented with leukocoria. Ocular hyperemia was associated with more advanced stages of retinoblastoma (p=0.004). Bilateral involvement was observed in 25.7% of the patients and at a significantly younger age (p=0.009). The presence of retinal detachment, vascularized lesions, and vitreous seeds significantly increased the likelihood of requiring enucleation. Discussion: This study presents an epidemiological description of retinoblastoma in Brazil, which highlights the significance of early detection. Delayed diagnosis is associated with a poorer visual prognosis and higher mortality rate, particularly in patients with unilateral disease. Risk factors for a more severe disease were retinal detachment, vascularized lesions, and vitreous seeds. The correlation between histopathological features and clinical outcomes was limited. Conclusion: Further studies are required to assess the influence of ocular hyperemia, fundoscopic assessment, and histopathologic findings on the prognosis of retinoblastoma. Moreover, it is critical to devise interventions to reduce the time-to-diagnosis in rural areas.

ABSTRACT: Acute abdomen cases are among the most prevalent and challenging illnesses in equine medicine. The diagnosis includes anamnesis and detailed clinical evaluation of the patient, allowing the gathering of several important information and, additionally, the use of complementary exams helps to define the diagnosis and prognosis of each case. This research applied the multiple correspondence analysis (MCA) in data referring to clinical examination information and outcome of horses with colic referred to a hospital in Rio Grande do Sul, Brazil. Fifty eight horses were included in the analysis and, it was possible to identify significant differences between the groups, survivors and non-survivors. Related to clinical signs, non-survivor cases are distinguished by severe pain, lack of motility, mucosal alteration, capillary refill time greater than 2sec, heart rate more than 48bpm and presence of nasogastric reflux. As complementary exams, hematocrits and blood lactate demonstrate significative difference among the groups. The cardiovascular parameters, including heart rate, mucosal color and capillary refill time, were the variables with the greatest contribution to discriminate animals that non-survive from those that were discharged. Thus, clinical evaluation should not be underestimated and complementary exams should be used in conjunction to seek a better prognosis. The MCA allowed to visualize the data and predict the outcome of the patients.

RESUMO: Os casos de abdome agudo estão entre as doenças mais prevalentes e desafiadoras na medicina equina. O diagnóstico inclui a realização de anamnese e avaliação clínica detalhada do paciente, permitindo a coleta de diversas informações importantes e, adicionalmente, a utilização de exames complementares ajuda a definir o diagnóstico e prognóstico de cada caso. O objetivo principal deste trabalho foi aplicar a análise de correspondência múltipla (ACM) em dados referentes ao exame clínico e desfecho de cavalos com cólica encaminhados para um hospital no Rio Grande do Sul, Brasil. Foram incluídos 58 cavalos na análise e foi possível identificar diferenças significativas entre os grupos, sobreviventes e não sobreviventes. Relacionado aos sinais clínicos, os casos de óbito distinguem-se por dor intensa, falta de motilidade, alteração da mucosa, tempo de preenchimento capilar maior que 2seg., frequência cardíaca maior que 48bpm e presença de refluxo nasogástrico. Como exames complementares, o hematócrito e o lactato sanguíneo demonstraram diferença significativa entre os grupos. Os parâmetros cardiovasculares, como batimento cardíaco, coloração de mucosas e tempo de preenchimento capilar, foram as variáveis com maior contribuição para diferenciar animais que não sobreviveram dos que receberam alta hospitalar. Assim, a avaliação clínica não deve ser subestimada e os exames complementares devem ser utilizados em conjunto para buscar um melhor prognóstico. A ACM permitiu visualizar os dados e prever o desfecho dos pacientes.

ABSTRACT Purpose: To describe the epidemiological and clinical profile of hospitalized patients with retinoblastoma in Brazil. Methods: Using data from the Hospital Cancer Registry of the Instituto Nacional de Câncer, patients with the morphological codes of retinoblastoma who were diagnosed between 2000 to 2018, aged 0–19 years, and followed up in registered hospitals (analytical cases) were selected. The relative and absolute frequencies of demographic, clinical, diagnostic, therapeutic, and outcome variables were described. Hospital performance indicators were calculated and compared between hospitals qualified and not qualified to treat pediatric oncology cases and between hospitals with different case volumes (<20, 20-75, >75 cases). Results: Of the 2,269 identified analytical cases from 86 institutions, 48% were from the Southeast, 54% were male, and 66% were aged <4 years. The proportion of missing data (NA) was too high for several variables. Approximately 84% of the patients were from the public health system, 40% had a positive family history, and 88% had unilateral involvement. The first treatment included surgery in 58.3% of the patients (NA=2), Approximately 36.6% of these patients achieved complete remission, 10.8% achieved partial remission, and 12.7% died (NA=59%). Hospital performance indicators were within the target in >90% of the patients. The median time between the first appointment and diagnosis (6 days, interquartile range [IQR] 1–14) was significantly lower and the median time to death was longer (343 days, IQR, 212-539) in high-volume hospitals (>75 cases) than in medium- and low-volume hospitals. Conclusions: Despite the high proportion of missing data, we found that the delay in diagnosis is due to prehospital factors. Additionally, there is a need for educational programs for healthcare professionals and families that emphasize early identification and referral to specialized centers. Future studies should focus on the impact of Hospital Cancer Registry data completeness on outcomes, causes of delay in diagnosis, regional inequalities, and barriers to accessing specialized services.

ABSTRACT Purpose: To determine the clinical outcomes in patients after type 1 Boston keratoprosthesis surgery and the significance of ultrasound biomicroscopy imaging for postoperative follow-up. Methods: This retrospective analysis included 20 eyes of 19 patients who underwent corneal transplantation with type 1 Boston keratoprosthesis between April 2014 and December 2021. Data on patient demographics, preoperative diagnosis, visual acuity, and postoperative clinical findings were analyzed. Results: Type 1 Boston keratoprosthesis implantation resulted in intermediate- and long-term positive outcomes. However, blindness and other serious complications such as glaucoma, retroprosthetic membrane formation, endophthalmitis, or retinal detachment also occurred. The use of ultrasound biomicroscopy imaging allowed for better evaluation of the back of the titanium plate, anterior segment structures, and the relationship of the prosthesis with surrounding tissues, which provided valuable postoperative information. Conclusion: Regular lifetime monitoring and treatment are necessary in patients who undergo Boston type 1 keratoprosthesis implantation for high-risk corneal transplantation. ultrasound biomicroscopy imaging can be a valuable imaging technique for the evaluation of patients with Boston type 1 keratoprosthesis, providing important information on anterior segment anatomy and potential complications. Further studies and consensus on postoperative follow-up protocols are required to optimize the management of patients with Boston type 1 keratoprosthesis.

ABSTRACT A young woman presented at our clinic with sudden visual loss in the right eye, recurrent vertigo, and right-sided tinnitus. We performed a complete ophthalmological evaluation. This revealed effects of the condition on the small arterioles of the peripheral retina. Susac syndrome is characterized by the clinical triad of retinal arteriolar occlusions, cochleovestibular manifestations, and encephalopathy (which can be identified by neuroimaging abnormalities).
