Background: Tuberculosis (TB)-related stigma has been well-documented. Since the emergence of the coronavirus disease 2019 (COVID-19), different organizations have been alerted to the fact that stigma could arise again. Due to stigma’s negative effects, this qualitative study aimed to explore the stigma felt by patients by evaluating the following: COVID-19 stigma and its temporal progression through the pandemic; stigma perceived by different patients with TB before and during COVID-19 pandemic; and difference perceived by individuals who contracted both diseases. Methods: A semi-structured interview was developed according to the available literature on the theme. It was performed individually in 2022 upon receiving signed informed consent. Participants were recruited with a purposive sampling approach by searching medical records. Those who currently or previously had pulmonary TB and/ or COVID-19 were included. Data were subjected to thematic analysis. Results: Nine patients were interviewed, including six (66.7%) females. The median age of patients was 51±14.7 years. Four participants (44.4%) had completed high school and four (44.4%) were never smokers. Three had both TB and COVID-19. Four only had TB and two only had COVID-19. Interviews identified eight main themes: knowledge and beliefs, with several misconceptions identified; attitudes towards the disease, varying from social support to exclusion; knowledge and education, assumed as of extreme importance; internalized stigma, with self-rejection; experienced stigma, with discrimination episodes; anticipated stigma, modifying actions for avoiding stigma; perceived stigma, with judgment by others prevailed; and temporal evolution of stigma. Conclusion Individuals expressed strong stigma for both diseases. De-stigmatization of respiratory infectious diseases is crucial for limiting stigma’s negative impact.

Background/Aims: Metastases of malignant melanoma (MM) are rare and associated with poor prognosis. The objective of this study was to analyze the clinical and endoscopic characteristics of gastric metastases of MM by systematically reviewing cases and case series involving patients diagnosed using upper gastrointestinal endoscopy. Methods: The PubMed and LILACS databases were searched. Reports containing individual patient data were included. Outcomes such as clinical data, endoscopic findings, treatments, and survival were analyzed. Results: A total of 88 studies with individual data from 113 patients with gastric metastases of MM were included. The primary sites of MM were the skin (62%), eyes (10%), and mucous membranes (6%). Most patients (56%) had multiple metastases in the stomach, located predominantly in the gastric body (approximately 80%). The overall survival rate at 2 years was 4%. There was a significant reduction in the survival of patients with multiple gastric metastases compared to that of patients with single metastasis (hazard ratio, 0.459; 95% confidence interval, 0.235−0.895; p=0.022). Conclusions Gastric metastases of MM have a poor prognosis, especially in patients with multiple implants in the stomach. Additional studies are needed to verify whether ocular and mucosal melanomas are associated with a higher risk of gastric metastases than that of cutaneous melanomas.

A simple, accurate and sensitive high-performance liquid chromatography (HPLC) method was developed, validated and applied to the determination of either theophylline or paracetamol in milk-based samples. The method allowed drug quantification in fresh and powdered milk with a relatively short run time of analysis and it was also successfully applied to the quantification of the drugs in solid dosage forms intended for pediatric use. Moreover, the main significant advantages over other published works are the simplicity of the sample preparation, reduced assay time and sample loss. The method meets the International Conference on Harmonization guideline for analytical methods validation regarding specificity,linearity,accuracy,precision, specificity and robustness as required by health authorities and applied by industry while designing and marketing new drug products.The technique encompasses the separation of the analytes with a reverse phase C18column under isocratic conditions and UV detection at 272 nm and 243 nm,respectively,for theophylline and paracetamol. The lower limit of quantification for both drugs was determined as 0.2μg/mL and the between-batch accuracy was 99.7%.This HPLC method allows quantification of theophylline and paracetamol in milk matrices and it can be applied in the design,development and production of milk-based pediatric dosage forms.

Honey allergy is a very rare, but serious health condition. In this study, we presented 1 patient who had anaphylaxis after the honey allergological investigation with skin prick-prick test with honey. Honey as a food has been associated to allergic reactions and as the increased consumption of honey in health food may increase the incidence of honey-related allergic reactions.

Stem cell-based therapy has been investigated in a number of degenerative and traumatic diseases, including spinal cord injury. In the present study, we investigated the use of autologous mesenchymal stem cells in the functional rehabilitation of a domestic cat presenting a compressive L1-L5 fracture. Bone marrow cells collected by puncture of the iliac crest were cultured to obtain mesenchymal stem cells three weeks before surgery. Hemilaminectomy was performed, followed by injection of the mesenchymal stem cells in the injured area. Clinical evaluation of the animal prior to surgery showed absence of pain, muscular tonus, and panniculi reflexes. Seven days after surgery and cell transplantation the examination revealed a progressive recovery of the panniculus reflexes and of the responses to superficial and deep pain stimuli despite the low proprioceptive and hyperreflexic ataxic hind limbs. Physiotherapy protocols were applied for clinical rehabilitation after surgery. The cat's first steps, three-minute weight-bearing, and intestine and urinary bladder partial reestablishment were observed 75 days post-surgery. Our results indicate the therapeutic potential of mesenchymal stem cells in chronic spinal cord injuries.

The drug-resistance of malaria parasites is the main problem in the disease control. The huge Brazilian biodiversity promotes the search for new compounds, where the animal kingdom is proving to be a promising source of bioactive compounds. The main objective of this study was to evaluate the antiplasmodial and cytotoxic activity of the compounds obtained from the toad venoms of Brazilian Amazon. Toad venoms were collected from the secretion of Rhinella marina and Rhaebo guttatus in Mato Grosso State, Brazil. The powder was extracted at room temperature, yielding 2 extracts (RG and RM) and a substance ('1') identified as a bufadienolide, named telocinobufagin. Growth inhibition, intraerythrocytic development, and parasite morphology were evaluated in culture by microscopic observations of Giemsa-stained thin blood films. Cytotoxicity was determined against HepG2 and BGM cells by MTT and neutral red assays. The 2 extracts and the pure substance ('1') tested were active against chloroquine-resistant Plasmodium falciparum strain, demonstrating lower IC₅₀ values. In cytotoxic tests, the 2 extracts and substance '1' showed pronounced lethal effects on chloroquine-resistant P. faciparum strain and low cytotoxic effect, highlighting toad parotoid gland secretions as a promising source of novel lead antiplasmodial compounds.

Background: and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. Methods: We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). Results: There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. Conclusions During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.
