RESUMEN

O câncer, frequentemente relacionado ao envelhecimento, impulsiona pacientes a buscarem tratamento hospitalar ou métodos alternativos, como plantas medicinais. Este estudo visou avaliar os perfis sociodemográfico e clínico e o consumo de plantas para fins medicinais entre pacientes idosos em tratamento oncológico no Hospital Araújo Jorge (HAJ). Dados de 55 pacientes foram analisados, abrangendo informações sociodemográficas, tipos de câncer, tratamento, a utilização de plantas medicinais, o objetivo de uso, as fontes de informações sobre plantas e se notaram alguma reação adversa após o consumo. A faixa etária mais encontrada foi 61 a 70 anos (67,27%), a maioria dos pacientes eram homens (63,64%), com ensino fundamental incompleto (32,73%), casados (56,36%) e que moram no interior de Goiás (43,64%). Quanto ao tratamento, a maioria realizava quimioterapia (40,00%) e o câncer gástrico foi mais relatado (14,54%). Sobre o uso de plantas medicinais, a maioria relatou simpatizar com o consumo (58,18%), e acredita em sua segurança devido à origem natural (59,37%). Informações sobre o uso de plantas medicinais eram obtidas com amigos, vizinhos e familiares (21,81%). Ao relatar sobre o consumo de plantas medicinais durante a quimioterapia, a maioria não percebeu nenhum efeito (40,63%). Foram citadas 17 plantas, que eram utilizadas no tratamento anticâncer (29,00%) e preparadas como infusões (18,75%) pelo uso das folhas frescas (60,00%), principalmente para uso interno (46,87%). Diante disso, a atenção farmacêutica se mostra vital para guiar pacientes nas práticas seguras e eficazes de consumo. Isso inclui direcionar sobre doses adequadas, efeitos colaterais e interações, garantindo bem-estar e prevenindo riscos à saúde.


Cancer, which is often related to ageing, drives patients to seek hospital treatment or alternative methods such as medicinal plants. This study aimed to evaluate the sociodemographic and clinical profile and the consumption of plants for medicinal purposes among elderly patients undergoing cancer treatment at the Araújo Jorge Hospital (AJH). Data from 55 patients was analyzed, covering sociodemographic information, types of cancer, treatment, the use of medicinal plants, the purpose of use, the source of information about plants and whether they noticed any adverse reactions after consumption. The most common age group was 61 to 70 years (67.27%), the majority of patients were men (63.64%), had incomplete primary education (32.73%), were married (56.36%) and lived in the interior of Goiás (43.63%). With regard to treatment, the majority were undergoing chemotherapy (40,00%) and gastric cancer was the most frequently reported (14.54%). With regard to the use of medicinal plants, the majority were sympathetic to their consumption (58.18%) and believed them to be safe due to their natural origin (59.37%). Information on the use of medicinal plants was obtained from friends, neighbors and family members (21.81%). When reporting on the consumption of medicinal plants during chemotherapy, the majority did not notice any effect (40.63%). Seventeen plants were mentioned, which were used for anticancer treatment (29,00%) and prepared as infusions (18.75%) with fresh leaves (60,00%), mainly for internal use (46.87%). In view of this, pharmaceutical care is vital to guide patients in safe and effective consumption practices. This includes guidance on appropriate doses, side effects and interactions, ensuring well-being and preventing health risks.

RESUMEN

Plastics derived from fossil fuels are used ubiquitously owing to their exceptional physicochemical characteristics. However, the extensive and short-term use of plastics has caused environmental challenges. The biotechnological plastic conversion can help address the challenges related to plastic pollution, offering sustainable alternatives that can operate using bioeconomic concepts and promote socioeconomic benefits. In this context, using soil from a plastic-contaminated landfill, two consortia were established (ConsPlastic-A and -B) displaying versatility in developing and consuming polyethylene or polyethylene terephthalate as the carbon source of nutrition. The ConsPlastic-A and -B metagenomic sequencing, taxonomic profiling, and the reconstruction of 79 draft bacterial genomes significantly expanded the knowledge of plastic-degrading microorganisms and enzymes, disclosing novel taxonomic groups associated with polymer degradation. The microbial consortium was utilized to obtain a novel Pseudomonas putida strain (BR4), presenting a striking metabolic arsenal for aromatic compound degradation and assimilation, confirmed by genomic analyses. The BR4 displays the inherent capacity to degrade polyethylene terephthalate (PET) and produce polyhydroxybutyrate (PHB) containing hydroxyvalerate (HV) units that contribute to enhanced copolymer properties, such as increased flexibility and resistance to breakage, compared with pure PHB. Therefore, BR4 is a promising strain for developing a bioconsolidated plastic depolymerization and upcycling process. Collectively, our study provides insights that may extend beyond the artificial ecosystems established during our experiments and supports future strategies for effectively decomposing and valorizing plastic waste. Furthermore, the functional genomic analysis described herein serves as a valuable guide for elucidating the genetic potential of microbial communities and microorganisms in plastic deconstruction and upcycling.

RESUMEN

Syringomatous tumor of the nipple is a benign, locally infiltrative tumor. There are reports in the literature of tumor recurrence in cases of incomplete excision. Clinical and mammographic findings in syringomatous tumors are like those of breast carcinoma and the pathologist has a fundamental role in final tumor diagnosis. Therefore, the aim of this study was to report a case of syringoma located in the areolar region. A 33-year-old woman reported that she had noticed a nodule in her left areolar region 4 years previously (February 2019). A breast ultrasound was performed, detecting intraparenchymatous breast cysts. Surgical resection of the nodule was indicated although it was not performed. Two years later, in August 2021, the patient underwent a mastopexy with prosthesis inclusion. Histopathology study of the surgical specimen revealed a syringomatous tumor with positive margins. Thirteen (13) months after diagnosis (September 3, 2021 - October 16, 2022), the patient is doing well and receives clinical follow-up.

RESUMEN

MATERIALS AND METHODS: An extensive literature search among six eletronic databases and Grey Literature was used to identify systematic reviews (S) that could respond if: in individuals diagnosed with OKC (P), is there any influence of the treatment method (I/C) on the recurrence rate of the lesion (O)? After evaluating all titles and abstracts and then applying the eligibility criteria, the included studies were read in full, and data were extracted based on a standardized sheet ordered in the PICO sequence. The assessment of the quality of the systematic reviews included, was determined by AMSTAR2, and final synthesis were descriptively made based on the results and quality of the systematic reviews. RESULTS: From a total of 19 included systematic reviews, it was observed that the most used treatment for OKC was enucleation, followed by enucleation with adjuvant techniques and marsupialization. The mean percentage of recurrence was 16,2%, and the highest OKC recurrence rate was 43.2% after simple enucleation. The use of adjuvant techniques promoted reductions in OKC recurrence rates. The overall methodological quality of systematic reviews was critically low, and this parameter demonstrate the need for more studies to facilitate the choose of the treatment. CONCLUSION: Despite being the most used treatment, simple enucleation is related to the highest rate of recurrence, except when performed after marsupialization/decompression. In addition, the use of adjuvant techniques has a strong impact on reducing the likelihood of recurrence. However, these findings are not conclusive because of the critically low quality of the systematic reviews.

RESUMEN

Fingolimod is a sphingosine-1-phosphate receptor modulator used to treat multiple sclerosis. While fingolimod has been associated with an increased risk of cryptococcal meningitis, its correlation with other deep mycoses remains unclear. In this study, we conducted a scoping review of fingolimod associated with histoplasmosis, based on a case report, a literature review, and data from the FDA Adverse Events Reporting System (FAERS) as of January 24th, 2023. A 30-year-old Brazilian woman diagnosed with relapsing-remitting multiple sclerosis, receiving a daily dose of 0.5 mg of fingolimod, presented with a two-month history of fever and unintended weight loss, accompanied by lymphadenopathy, splenomegaly, and lung involvement was investigated. Biopsy of a lung nodule revealed fungal structures suggestive of Histoplasma sp. Additionally, serological testing yielded positive for Histoplasma capsulatum. Disseminated histoplasmosis should be considered in the differential diagnosis of febrile syndromes in patients undergoing fingolimod therapy for multiple sclerosis, particularly in the Americas, where this mycosis is endemic. Treatment with itraconazole and modification of immunotherapy can achieve excellent clinical outcomes.

RESUMEN

Preclinical evidence suggests that probiotic administration may exert an anti-inflammatory effect and reduce autonomic dysfunction and blood pressure. This study evaluated the effects of probiotic therapy on inflammatory biomarkers and characterized the correlations between inflammation and cardiac autonomic function in women with arterial hypertension. Women were randomized into probiotics (n = 20) or placebo (n = 20). The probiotic group received 109 CFU/day of Lactobacillus (L.) paracasei LPC-37, L. rhamnosus HN001, L. acidophilus NCFM, and Bifidobacterium lactis HN019, and the placebo group received polydextrose. Clinical, electrocardiogram, heart rate variability (HRV) analysis, and cytokine levels were assessed at baseline and after 8 weeks. Women who received probiotics for 8 weeks had increased serum levels of IL-17A (p = 0.02) and decreased INF-γ (p = 0.02) compared to baseline. Probiotic supplementation increased serum levels of IL-10 compared to the placebo group (p = 0.03). Probiotic or placebo administration did not change serum levels of TNFα and IL-6. Serum levels of IL-2 (p = 0.001, and p = 0.001) and IL-4 (p = 0.001, and p = 0.001) were reduced in women receiving placebo or probiotics, respectively. Correlations between HRV indices and inflammatory variables showed that INF-γ was positively correlated with heart rate (HR) and sympathetic HRV indices and negatively correlated with vagal HRV indices. IL-10 was negatively correlated with HR and sympathetic HRV indices. IL-6 was negatively correlated with parasympathetic HRV indices and positively correlated with SD2/SD1 ratio. Probiotic therapy has a discreet anti-inflammatory effect in hypertensive women, and pro-inflammatory cytokines were negatively correlated with vagal modulation and positively correlated with sympathetic modulation of HRV. The clinical trial was registered in the Brazilian Registry of Clinical Trials (ReBEC) with the identification RBR-9mj2dt.

RESUMEN

OBJECTIVES: The objective of this study is to describe the rehabilitation of individuals with Congenital Malformations (CMF) during the use of an External Fixator (EF) in Aquatic Therapy (AT) and to analyze the association between diagnosis, EF type and location with rehabilitation process outcomes, surgical intervention, and adverse effects. METHODS: This retrospective study included 29 medical records from which the personal and rehabilitation data of the patient were collected. The AT used was described and the outcome variables were associated. The medical records were selected by screening the database of the CMF clinic at the AACD. The inclusion criteria were participants with CMF who used EF treated between 2011 and 2019 of both genders and without age restriction. The exclusion criteria were incomplete medical record data or not undergoing AT while using EF. The extracted data included diagnosis, gender, age, EF type and location, objective of the surgery, adverse events, surgical interventions, time of rehabilitation in AT, physiotherapeutic objectives, and rehabilitation process outcomes in AT. RESULTS: The mean age of the participants was 12.1 ± 3.99 years, with male predominance (55 %) and hemimelia cases (37 %). The most used EF was circular (51 %), located in the femur (37 %), and the main objective of surgery was bone lengthening (52 %). The most recurrent adverse effect was infection (62 %) and 76 % completed AT. There was no association between the variables analyzed. CONCLUSIONS: It was possible to describe CMF rehabilitation with EF in AT. There was no association between the variables analyzed.

RESUMEN

OBJECTIVES: To critically analyse and discuss oral hygiene protocols in the hospital environment in patients admitted to the ICU, through a systematic review of the literature. METHODS: The electronic search was performed on Pubmed, Cochrane, Web of Science and Google Scholar databases. The indexing keywords according to the PRISMA protocol were: 'hospital dentistry', 'oral health', 'oral care' and 'intensive care unit'. RESULTS: The initial search resulted in a total of 2671 articles. Pre-selection based on titles led to the exclusion of 2510 articles and the remaining 36 were selected for abstract reading. After analysing the eligibility of the articles, eight studies were included in the review and submitted to qualitative analysis. CONCLUSION: It can be concluded that cleaning with a soft bristle brush, use of chlorhexidine and lip moisturizing are methods commonly used in dental care actions in patients hospitalized in intensive care units.

RESUMEN

The aim of this study was to evaluate the mediation role of muscle quantity in the relationship between physical fitness and cardiometabolic risk factors (CMRF) in adolescents. This cross-sectional study conducted with 120 adolescents of both sexes, aged between 10 and 17 years. Body mass, height, fat mass (FM), lean mass, blood pressure, high-density lipoprotein, low-density lipoprotein, triglycerides, glucose, insulin, cardiorespiratory fitness (CRF) and 1 repetition maximum strength (1-RM) with evaluation of the leg press 45° (RM-leg), bench press (RM-bench) and arm curl (RM-arm). Body mass index z-score, appendicular skeletal muscle mass, appendicular skeletal muscle mass index, lean mass index (LMI), muscle-to-fat ratio (MFR), age at peak height velocity, and CMRF z-score were calculated. The direct relation between FM and CMRF was mediated by the LMI (26%) and inverse relation between CRF and CMRF was mediated by the LMI (26%). For girls, the direct relation between FM and CMRF was mediated by the LMI (32%); the inverse relation between CRF, RM-leg, RM-arm and CMRF was mediated by the LMI (32%, 33%, and 32%, respective). For boys, the indirect effect was not significant, indicating that LMI is not a mediator in the relation between FM, CRF, 1-RM with CMRF. The direct relation between RM-leg and CMRF was mediated by the MRF (16%). This finding evidenced the importance of promoting a healthy lifestyle to improve physical fitness levels and the quantity of muscle mass in adolescents.

RESUMEN

The objective of this cross-sectional study was to assess eating competence (EC) and the adherence to the division of responsibility in child feeding (sDOR) of Brazilian caregivers of children with celiac disease (CD). It also examined the association between EC and sDOR, children's adherence to a gluten-free diet, and sociodemographic data. This study administered a survey set that included sociodemographic data, health-related data, eating habits, and the instruments ecSI2.0TMBR and sDOR.2-6yTM BR, validated for a Brazilian population. The sample comprised 50 caregivers of children with CD (between 24 and 72 months of age). The participants following a gluten-free diet (GFD) presented higher scores for all EC domains and the total EC. The total EC scores were higher for the participants over 40 y/o, frequently having meals as a family, with their children consuming more than three servings of fruit and at least one serving of vegetables daily and complying with a GFD. Different from the EC, the sDOR.2-6yTM scores did not differ between the participants complying with a GFD. The sDOR.2-6yTM mealtime structure domain scores were significantly associated with the EC eating attitude, food acceptance, contextual skills, and total. These findings support the need for greater attention to exploring the division of responsibility in feeding and EC in pediatric celiac disease, potentially enhancing intervention strategies for patients and their families.

RESUMEN

BACKGROUND: The sphenoid bone is an irregular, unpaired, symmetrical bone located in the middle of the anterior skull and is involved in craniofacial growth and development. Since the morphology of Sella turcica (ST) is associated with different craniofacial patterns, this study aimed to investigate if there is a correlation between ST morphology on the one hand and sagittal craniofacial patterns on the other hand. METHODS: This study was conducted with a convenience sample that included Brazilian individuals undergoing orthodontic treatment. Lateral cephalograms were used to evaluate the calcification pattern and morphology of ST, as well as skeletal class by analyzing the ANB angle. Pearson's chi-square test with Bonferroni post-hoc test was performed to evaluate the association between ST calcification pattern and morphology, and anteroposterior skeletal malocclusion. The established significance level was 0.05. RESULTS: The study collective was comprised of 305 orthodontic patients (178 (58.4 %) female, 127 (41.6 %) male), who had a mean age of 23.2 (±10.6) years. 131 participants (42.9 %) presented skeletal class I, 142 (46.6%) skeletal Class II, and 32 (10.5%) had a skeletal class III. The degree of prognathism of the mandible showed a homogenous distribution within the study collective (91 (29.9 %) orthognathic, 100 (32.9 %) retrognathic, 113 (37.2 %) prognathic mandible). Concerning the maxilla, 92 (30.2%) individuals presented an orthognathic upper jaw, whereas 60 (19.7%) showed maxillary retrognathism and 153 (50.2%) maxillary prognathism. Compared to patients with skeletal class I, skeletal class III individuals presented significantly more hypertrophic posterior clinoid process (p<0.007) and pyramidal shape of the dorsum of the ST (p<0.038). CONCLUSIONS: Our results suggest that the hypertrophic posterior clinoid process and pyramidal shape of the ST dorsum are more prevalent in individuals with skeletal class III malocclusion.

RESUMEN

Immunization with various Leishmania species lacking centrin induces robust immunity against a homologous and heterologous virulent challenge, making centrin mutants a putative candidate for a leishmaniasis vaccine. Centrin is a calcium-binding cytoskeletal protein involved in centrosome duplication in higher eukaryotes and Leishmania spp. lacking centrin are unable to replicate in vivo and are non-pathogenic. We developed a centrin-deficient Leishmania braziliensis (LbCen-/-) cell line and confirmed its impaired survival following phagocytosis by macrophages. Upon experimental inoculation into BALB/c mice, LbCen-/- failed to induce lesions and parasites were rapidly eliminated. The immune response following inoculation with LbCen-/- was characterized by a mixed IFN-γ, IL-4, and IL-10 response and did not confer protection against L. braziliensis infection, distinct from L. major, L. donovani, and L mexicana centrin-deficient mutants. A prime-boost strategy also did not lead to a protective immune response against homologous challenge. On the contrary, immunization with centrin-deficient L. donovani (LdonCen-/-) cross-protected against L. braziliensis challenge, illustrating the ability of LdonCen-/- to induce the Th1-dominant protective immunity needed for leishmaniasis control. In conclusion, while centrin deficiency in L. braziliensis causes attenuation of virulence, and disrupts the ability to cause disease, it fails to stimulate a protective immune response.

RESUMEN

This study assessed the color-matching ability and color recovery of unprepared teeth when using single-shade composites and a universal composite in large restorations. Buccal and palatine surface colors of molars were measured with a spectrophotometer (CIELAB) before preparing round cavities (6 mm in diameter, 2 mm in depth). The cavities were randomly filled with a single-shade composite (Omnichroma, Diamond One, or Vittra APS Unique) or a universal composite (Filtek Universal). Color measurements of the restored cavities were taken, and overall color differences (ΔEab and ΔE00) and differences in the whitening index for dentistry (ΔWID) from baseline were calculated. Additionally, visual assessments of a color match to the surrounding enamel were performed by forty evaluators (laypersons and undergraduate students of dentistry) in a viewing booth under illuminant D65, with rating scores from 0 (no color mismatch) to 4 (not acceptable). Data were analyzed using RM or one-way ANOVA (α = 0.05). Results showed that the restorations generally exhibited whiter colors (WID ranged from 27.9 to 41.3) than the unprepared teeth (WID ranged from 15.9 to 19.3). The composite Filtek Universal demonstrated the lowest color discrepancy (ΔWID = 8.6; ΔE00 = 10.8; and ΔE00 = 6.2), and no significant differences were observed among the evaluated single-shade composites. Furthermore, all composites showed similar and adequate color matches to the surrounding enamel. However, it is important to note that despite their ability to match the surrounding enamel reasonably, none of the composites evaluated in large restorations fully recovered the color observed in unprepared teeth.

RESUMEN

Background: Identification of unvaccinated children is important for preventing deaths due to infections. Number of siblings and birth order have been postulated as risk factors for zero-dose prevalence. Methods: We analysed nationally representative cross-sectional surveys from 85 low and middle-income countries (2010-2020) with information on immunisation status of children aged 12-35 months. Zero-dose prevalence was defined as the failure to receive any doses of DPT (diphtheria-pertussis-tetanus) vaccine. We examined associations with birth order and the number of siblings, adjusting for child's sex, maternal age and education, household wealth quintiles and place of residence. Poisson regression was used to calculate zero-dose prevalence ratios. Findings: We studied 375,548 children, of whom 13.7% (n = 51,450) were classified as zero-dose. Prevalence increased monotonically with birth order and with the number of siblings, with prevalence increasing from 11.0% for firstborn children to 17.1% for birth order 5 or higher, and from 10.5% for children with no siblings to 17.2% for those with four or more siblings. Adjustment for confounders attenuated but did not eliminate these associations. The number of siblings remained as a strong risk factor when adjusted for confounders and birth order, but the reverse was not observed. Among children with the same number of siblings, there was no clear pattern in zero-dose prevalence by birth order; for instance, among children with two siblings, the prevalence was 13.0%, 14.7%, and 13.3% for firstborn, second, and third-born, respectively. Similar results were observed for girls and boys. 9513 families had two children aged 12-35 months. When the younger sibling was unvaccinated, 61.9% of the older siblings were also unvaccinated. On the other hand, when the younger sibling was vaccinated, only 5.9% of the older siblings were unvaccinated. Interpretation: The number of siblings is a better predictor than birth order in identifying children to be targeted by immunization campaigns. Zero-dose children tend to be clustered within families. Funding: Gavi, the Vaccine Alliance.

RESUMEN

Solar ultraviolet-B (UVB) radiation has increased due to stratospheric ozone depletion, climate and ecosystem changes and is a driver of amphibian population declines. Photoenzymatic repair (PER) is a critical mechanism for limiting UVB lethality in amphibian larvae. However, the link between PER and the UVB-induced effects remains understudied through long-term investigations in vivo. Here, we assessed how larval PER determines the lethal and sublethal effects induced by environmentally relevant acute UVB exposure until the juvenile phase in the Neotropical frog Odontophrynus americanus. We conducted laboratory-based controlled experiments in which tadpoles were or were not exposed to UVB and subsequently were exposed to light (for PER activation) or dark treatments. Results showed that the rates of mortality and apoptosis observed in post-UVB dark treatment are effectively limited in post-UVB light treatment, indicating PER (and not dark repair, i.e. nucleotide excision repair) is critical to limit the immediate genotoxic impact of UVB-induced pyrimidine dimers. Nonetheless, even tadpoles that survived UVB exposure using PER showed sublethal complications that extended to the juvenile phase. Tadpole responses included alterations in morphology, chromosomal instability, increased skin susceptibility to fungal proliferation, as well as increased generation of reactive oxygen species. The short-term effects were carried over to later stages of life because metamorphosis time increased and juveniles were smaller. No body abnormalities were visualized in tadpoles, metamorphs, and juveniles, suggesting that O. americanus is UVB-resistant concerning these responses. This study reveals that even frog species equipped with an effective PER are not immune to carry-over effects from early UVB exposure, which are of great ecological relevance as late metamorphosis and smaller juveniles may impact individual performance and adult recruitment to breeding. Future ecological risk assessments and conservation and management efforts for amphibian species should exercise caution when linking PER effectiveness to UVB resistance.

RESUMEN

Obesity results from an energy imbalance and has been considered an epidemic due to its increasing rates worldwide. It is classified as a low-grade chronic inflammatory disease and has associated comorbidities. Different nutritional strategies are used for the purpose of weight loss, highlighting low-carbohydrate (LC) diets, ketogenic diets, and intermittent fasting (IF). These strategies can lead to metabolic and behavioral changes as they stimulate different biochemical pathways. Therefore, this study evaluated memory, energy metabolism, neuroinflammation, oxidative stress, and antioxidant defense parameters in mice subjected to an LC diet, ketogenic diet (KD), or IF. Eighty male Swiss mice, 60 days old, were divided into 4 groups: control, LC, KD, or IF. Body weight was measured weekly, and food intake every 48 h. After 15 days of nutritional interventions, the animals were subjected to the behavioral object recognition test and subsequently euthanized. Then, visceral fat was removed and weighed, and the brain was isolated for inflammatory and biochemical analysis. We concluded from this study that the LC and KD strategies could damage memory, IF improves the production of adenosine triphosphate (ATP), and the LC, KD, and IF strategies do not lead to neuroinflammatory damage but present damage at the level of oxidative stress.

RESUMEN

INTRODUCTION: Bee venom has therapeutics and pharmacological properties. Further toxicological studies on animal models are necessary due to the severe allergic reactions caused by this product. METHOD: Here, Caenorhabditis elegans was used as an in vivo toxicity model, while breast cancer cells were used to evaluate the pharmacological benefits. The bee venom utilized in this research was collected from Apis mellifera species found in Northeast Brazil. The cytotoxicity caused by bee venom was measured by MTT assay on MDA-MB-231 and J774 A.1 cells during 24 - 72 hours of exposure. C. elegans at the L4 larval stage were exposed for three hours to M9 buffer or bee venom. Survival, behavioral parameters, reproduction, DAF-16 transcription factor translocation, the expression of superoxide dismutase (SOD), and metabolomics were analyzed. Bee venom suppressed the growth of MDA-MB-231 cancer cells and exhibited cytotoxic effects on macrophages. Also, decreased C. elegans survival impacted its behaviors by decreasing C. elegans feeding behavior, movement, and reproduction. RESULTS: Bee venom did not increase the expression of SOD-3, but it enhanced DAF-16 translocation from the cytoplasm to the nucleus. C. elegans metabolites differed after bee venom exposure, primarily related to aminoacyl- tRNA biosynthesis, glycine, serine and threonine metabolism, and sphingolipid and purine metabolic pathways. Our findings indicate that exposure to bee venom resulted in harmful effects on the cells and animal models examined. CONCLUSION: Thus, due to its potential toxic effect and induction of allergic reactions, using bee venom as a therapeutic approach has been limited. The development of controlled-release drug strategies to improve this natural product's efficacy and safety should be intensified.

RESUMEN

Objective: To compare the outcomes of patients undergoing conventional gastrointestinal surgeries who developed COVID-19 to those who were not infected. Method: Descriptive comparative study. Data were collected from 142 medical records, during the period from March 2020 (begin-ning of the pandemic in Brazil) to December 2021. Study approved by the Research Ethics Committee (CAAE: 29473520.2.0000.5392). Results: The pro-file of the patients was mostly classified as ASA 2 and 3. There was the presence of at least one chronic disease in all patients with COVID-19 and in most patients without COVID-19. The mean BMI for patients with COVID-19 was type I obesity and overweight for the rest of the sample (p=0.043). There was a predominance of females among patients affected by COVID-19. Complications were longer postoperative hospital stay (p=0.015) and need for surgical approach (p=0.034). Conclusions: The profile of surgical patients with COVID-19 was linked to the presence of comorbidities, lon-ger duration of the surgical procedure and high BMI. Complications associated with the presence of COVID-19 were longer postoperative hospital stays and surgical reoperation. (AU)


Objetivo: Comparar os desfechos de pacientes submetidos a cirurgias gastrointestinais convencionais que desenvolveram coronavirus disease(COVID-19) com aqueles que não estavam contaminados. Método: Estudo comparativo descritivo. Foram coletados dados de 142 prontuários desde março de 2020 (início da pandemia no Brasil) até dezembro de 2021. Estudo aprovado pelo Comitê de Ética em Pesquisa (CAAE: 29473520.2.0000.5392). Resultados: O perfil dos pacientes foi, em sua grande maioria, classificação ASA 2 e 3 e presença de ao menos uma doença crônica em todos os pacientes com COVID-19 e na maioria daqueles sem COVID-19. O índice de massa corpórea (IMC) médio para os pacientes com COVID-19 foi obesidade tipo I e sobrepeso para o restante da amostra (p=0,043). Houve predominância do sexo feminino entre os pacientes acometidos por COVID-19. As complicações foram maior tempo de internação pós-operatória (p=0,015) e necessidade de reabordagem cirúrgica (p=0,034). Conclusão: O perfil dos pacientes cirúr-gicos com COVID-19 esteve atrelado à presença de comorbidades, maior duração do procedimento cirúrgico e IMC elevado. As complicações associadas à presença de COVID-19 foram maior tempo de internação pós-operatória e necessidade de reabordagem cirúrgica. (AU)
