RESUMEN
Veterinary oncology has experienced significant evolution over the last few decades, with chemotherapy being currently applied to several neoplasms with therapeutic success. Traditionally, chemotherapy protocols are based on classic cytostatic drugs under the concept of maximum tolerated dose (MTD), which has been associated with a greater risk of toxicity and resistance. Thus, new therapeutic alternatives have emerged, such as metronomic chemotherapy (MC), introducing a new paradigm in cancer treatment. MC consists of administering low doses of chemotherapy drugs continuously over a long period of time, modulating the tumour microenvironment (TME) due to the combination of cytotoxic, antiangiogenic and immunomodulatory effects. This multi-targeted therapy has been described as a treatment option in several canine and feline cancers since 2007, with positive results already published in the literature, particularly in mammary carcinomas and soft tissue sarcomas in dogs. The aim of this review article is to describe the current knowledge about the use of MC in small animal oncology, with emphasis on its mechanisms of action, the most commonly used drugs and clinical outcome.
RESUMEN
The emergence of SARS-CoV-2, leading to the widespread outbreak of COVID-19, has unveiled a spectrum of symptoms and severe health complications, challenging healthcare systems and impacting millions of lives worldwide. To analyze events allegedly attributable to vaccination or immunization (ESAVI) against SARS-CoV-2 (COVID-19) in the municipality of Santarém, in the interior of the state of Pará, an epidemiological, descriptive study was conducted using data from e-SUS Notifica in Santarém/PA from January 2021 to January 2022. The analyzed data for ESAVI cases included the administered immunobiologicals (Coronavac, Covishield, and Comirnaty), the type of event, case progression, time in days between immunobiological administration, and symptom onset, causality, and classification of ESAVI according to the vaccine package inserts. The incidence rate of ESAVI due to the COVID-19 vaccine was 17 per 100,000 doses administered in the municipality. According to the ESAVI classification, 14.0% were classified as Serious ESAVI (ESAVIG) (IR: 8.12 per 100,000 doses administered), with 100% of these events resulting in full recovery without sequelae, and 82.4% of reported cases were classified as Non-Serious ESAVI (ESAVING) (IR: 47.78), of which 3.60% were immunization errors (IR: 2.08 IE per 100,000 doses). This study fosters discussion on the importance of accurate recording of ESAVI related to COVID-19 vaccines, demonstrating their safety for the population.
RESUMEN
OBJECTIVE: To assess the effect of recombinant growth hormone (rGH) on body composition and metabolic profile of prepubertal short children born small for gestational age (SGA) before and after 18 months of treatment. METHODS: It is a clinical, non-randomized, and paired study. Children born SGA, with birth weight and/or length <-2 standard deviations (SD) for gestational age and sex, prepubertal, born at full term, of both genders, with the indication for treatment with rGH were included. The intervention was performed with biosynthetic rGH at doses ranging from 0.03 to 0.05 mg/kg/day, administered subcutaneously, once a day at bedtime. Total lean mass (LM) and total fat mass (FM) were carried out using dual-energy X-ray absorptiometry (DXA), and the metabolic profile was assessed for insulin, glycemia, IGF-1 levels and lipid profile. RESULTS: Twelve patients (nine girls, 8.17±2.39 y) were evaluated; three patients dropped out of the study. There was an increase of LM adjusted for length (LMI) (p=0.008), LMI standard deviation score (SDS) adjusted for age and sex (p=0.007), and total LM (p<0.001). The percentage of body fat (BF%) and abdominal fat (AF) remained unaltered in relation to the beginning of treatment. Among the metabolic variables, blood glucose remained within normal levels, and there was a reduction in the number of participants with altered cholesterol (p=0.023). CONCLUSIONS: The effect of rGH treatment was higher on LM than in FM, with increased LM adjusted for length and standardized for age and sex. Glycemia remained within the normal limits, and there was a decreased number of children with total cholesterol above the recommended levels.

Introduction: Introduction: the dietary intake of individuals with phenylketonuria (PKU) may vary widely according to different cultural eating habits, lifestyle, access to multidisciplinary team, and metabolic formulas available. Thus, knowing the dietary intake of this population makes it possible to tailor nutritional treatment strategies to impact their health. Objective: to analyze the evidence on the dietary intake of individuals with PKU. Methods: an integrative literature review was conducted on the dietary intake of individuals with PKU in the databases PUBMED, BIREME and Science Direct. Original articles that addressed the energy and macronutrient food intake of children, adolescents and/or adults with PKU were included in the study, without time restriction, in any language. A total of 384 articles were found and 27 articles were selected and analyzed. Results: evidence about the nutritional composition of their diet showed that individuals with PKU consume between 1160-2721 kcal of energy -7.2-17.4 % (32.4-76.9 g) of energy as protein, 45.9-69.2 % of energy as carbohydrates, 16.6-39 % of energy as lipids- and between 7.6 and 20 g of fiber. Conclusion: most individuals with PKU have low energy, protein and fiber intake, adequate lipid intake, and high carbohydrate intake. Metabolic control of the disease is still a challenge in all countries. Nutritional strategies to improve dietary nutritional composition and phenylalanine blood levels in individuals with PKU remain an urgent issue.
Introducción: Introducción: la ingesta dietética de los individuos con fenilcetonuria (PKU) puede variar ampliamente debido a los diferentes hábitos culturales de alimentación, el estilo de vida, el acceso al equipo multidisciplinar y las fórmulas metabólicas disponibles. Por ello, conocer la ingesta dietética de esta población permite adaptar las estrategias de tratamiento nutricional para incidir en su salud. Objetivo: analizar la evidencia sobre la ingesta dietética de individuos con PKU. Métodos: se realizó una revisión bibliográfica integradora sobre la ingesta dietética de las personas con PKU en las bases de datos PUBMED, BIREME y Science Direct. El estudio incluyó artículos originales que abordaran la ingesta alimentaria de energía y macronutrientes de niños, adolescentes y/o adultos con PKU, sin restricción de tiempo, en cualquier idioma. Se encontraron 384 artículos y se seleccionaron y analizaron 27. Resultados: la evidencia de la composición nutricional de la dieta mostró que los individuos con PKU consumen entre 1160 y 2721 kcal de energía 7,2-17,4 % (32,4-76,9 g) de la energía en forma de proteínas, 45,9-69,2 % de la energía en carbohidratos, 16,6-39 % de la energía en lípidos y entre 7,6 y 20 g de fibra. Conclusiones: la mayoría de los individuos con PKU tienen una ingesta baja de energía, proteínas y fibra, una ingesta adecuada de lípidos y una ingesta alta de hidratos de carbono. El control metabólico de la enfermedad sigue siendo un reto en todos los países. Siguen siendo urgentes las estrategias nutricionales para mejorar la composición nutricional de la dieta y los niveles de fenilalanina en sangre de los individuos con PKU.

RESUMO Objetivo: Avaliar o efeito do hormônio de crescimento recombinante (rHC) na composição corporal e no perfil metabólico de crianças pré-púberes com baixa estatura, nascidas pequenas para a idade gestacional (PIG) antes e depois de 18 meses de tratamento. Métodos: Estudo clínico, não randomizado e pareado. Foram incluídas crianças nascidas PIG, com peso e/ou altura ao nascer <-2 desvios padrão (DP) para idade gestacional e sexo, pré-púberes, nascidas a termo, de ambos os sexos, com indicação de tratamento com rGH. A intervenção foi realizada com rGH biossintético com doses variando de 0,03 a 0,05 mg/kg/dia, administrado por via subcutânea, uma vez ao dia ao deitar-se. A massa magra total (LM) e a massa gorda total (MG) foram determinadas por meio de absorciometria de raios X de dupla energia (DXA), e o perfil metabólico foi avaliado com dosagens de insulina, glicemia, IGF-1 e perfil lipídico. Resultados: Doze pacientes (nove meninas, 8,17±2,39 anos) foram avaliados; três pacientes abandonaram o estudo. Houve aumento da LM ajustada para estatura (LMI) (p=0,008), LMI standard deviation scores (SDS) ajustada para idade e sexo (p=0,007) e LM total (p<0,001). O percentual de gordura corporal (GC%) e gordura abdominal (AF) permaneceu inalterado em relação ao início do tratamento. Entre as variáveis metabólicas, a glicemia manteve-se na normalidade, e houve redução do número de participantes com colesterol alterado (p=0,023). Conclusões: O efeito do tratamento com HCr foi maior na MM do que na MG, com o aumento da MM ajustada para altura e padronizada para idade e sexo. A glicemia permaneceu normal e houve redução do número de crianças com colesterol total acima do recomendado.
RESUMEN
OBJECTIVE: To evaluate the efficacy and outcomes of the surgical treatment for pelvic organ prolapse (POP) in stages III and IV by sacrospinous ligament fixation (SSLF) or uterosacral ligament suspension (USLS) by comparing anatomical and subjective cure rates and quality-of-life parameters (through the version validated for the Portuguese language of the Prolapse Quality of Life [P-QoL] questionnaire) under two definitions: genital prolapse Ba, Bp, and C < -1 (stage I) and Ba, Bp, and C ≤ 0 (stage II). MATERIALS AND METHODS: After we obtained approval from the Ethics Committee (under CAAE 0833/06) and registered the study in ClinicalTrials.gov (NCT01347021), 51 patients were randomized into two groups: the USLS group (N = 26) and the SSLF group (N = 25), with follow-up 6 and 12 months after the procedures. RESULTS: There was a significant improvement in the P-QoL score and anatomical measurements of all compartments in both groups after 12 months (p < 0.001). The anatomical cure rates in the USLS and SSLF groups, considering stage 1, were of 34.6% and 40% (anterior) respectively; of 100% both for groups (apical); and of 73.1% and 92% (posterior) respectively. The rates of adverse outcomes were of 42% (N = 11) and 36% (N = 11) for the USLS and SSLF groups respectively (p = 0.654), and those outcomes were excessive bleeding, bladder perforation (intraoperative) or gluteal pain, and urinary infection (postoperative), among others, without differences between the groups. CONCLUSION: High cure rates in all compartments were observed according to the anatomical criterion (stage I), without differences in P-QoL scores and complications either with USLS or SSLF for the surgical treatment of accentuated POP.
OBJETIVO: Avaliar a eficácia e os resultados do tratamento cirúrgico para prolapso de órgãos pélvicos (POP) nos estágios III e IV, por meio da técnica de fixação do ligamento sacroespinal (FLSE) ou suspensão do ligamento útero-sacro (SLUS), ao comparar os índices de cura anatômicos, subjetivos, e os parâmetros de qualidade de vida (por meio do questionário Prolapse Quality of Life [P-QoL] validado para a língua portuguesa) sob duas definições: prolapso genital Ba, Bp e C < −1 (estágio I) e Ba, Bp e C ≤ 0 (estágio II). MATERIAIS E MéTODOS: Após aprovação do Comitê de Ética (CAAE 0833/06) e registro no ClinicalTrials.gov (NCT01347021), 51 pacientes foram randomizadas em dois grupos: grupo SLUS (N = 26) e (2) grupo FLSE (N = 25), com seguimento de 6 e 12 meses. RESULTADOS: Houve melhora significativa nas pontuações no P-QoL e nas medidas anatômicas de todos os compartimentos em ambos os grupos após 12 meses (p < 0,001). As taxas de cura anatômica nos grupos SLUS e FLSE , considerando o estágio 1, foram de 34,6% e 40% (anterior), respectivamente; de 100% em ambos os grupos (apical); e de 73,1% e 92% (posterior), respectivamente. As taxas de resultados adversos foram de 42% (N = 11) e 36% (N = 11), respectivamente, nos grupos SLUS e FLSE (p = 0,654), e elas foram sangramento excessivo, perfuração da bexiga (intraoperatória) ou dor glútea, e infecção urinária (pós-operatória), entre outras, sem diferenças entre os grupos. CONCLUSãO: Altas taxas de cura em todos os compartimentos foram observadas segundo critério anatômico (estágio I), sem diferença quanto às pontuações no P-QoL e às complicações tanto com SLUS quanto com FLSE para o tratamento cirúrgico de POP acentuado.

BACKGROUND: Measuring resting energy expenditure (REE) in individuals living with phenylketonuria (PKU) using indirect calorimetry (IC) is unusual in healthcare facilities because it requires specific protocols and expensive equipment. Considering that determining REE is crucial for devising nutritional strategies for the management of PKU, the aim of this study was to identify the predictive equations that provide the best estimates of REE in children and adolescents living with PKU and to propose a predictive equation for determining REE in this population. METHODS: An REE concordance study was conducted with children and adolescents living with PKU. Anthropometric and body composition assessments using bioimpedance and REE assessment using IC were performed. The results were compared to 29 predictive equations. RESULTS: Fifty-four children and adolescents were evaluated. The REE obtained using IC differed from all estimated REE, except Henry's equation for male children (p = 0.058). Only this equation showed good agreement (0.900) with IC. Eight variables were associated with the REE obtained using IC with emphasis on fat-free mass (kg) (r = 0.786), weight (r = 0.775), height (r = 0.759) and blood phenylalanine (r = 0.503). With these variables, three REE equations were suggested, with R2 = 0.660, 0.635 and 0.618, respectively, and the third equation, which involves weight and height, showed adequate sample size for a statistical power of 0.942. CONCLUSION: Most equations, not specific for individuals living with PKU, overestimate the REE of this population. We propose a predictive equation for assessing REE for children and adolescents living with PKU to be used in settings where IC is not available.

INTRODUCTION: To date, there is a gap regarding resting energy expenditure (REE) in adults with phenylketonuria (PKU), whether PKU type and time of diagnosis interfere with REE, and whether the available predictive equations are valid in this population. OBJECTIVE: To compare the REE of adult subjects with PKU with healthy subjects and secondarily, examine the REE of adults with PKU according to type and time of diagnosis, and check the agreement of commonly used predictive equations of REE. METHODS: Concordance study with adults with PKU and a comparison group (CG) with healthy adults. Anthropometric and body composition assessments and REE assessment by indirect calorimetry (IC) were performed. The results obtained by IC were compared with predictive equations. RESULTS: Sixty-nine adults were evaluated (PKU: 36; CG: 33). The REE of adults with mild and classic PKU is similar (p>.05) and similar to CG (p>.05). The REE of individuals with early diagnosis is higher (p < .05) than the REE of individuals with late diagnosis. The REE obtained by IC differed (p < .05) from all estimated REE. CONCLUSION: Late diagnosis of PKU showed lower REE compared to individuals with early diagnosis. The REE of adults with PKU does not differ in relation to the type of PKU, nor does it differ from the CG. Predictive equations overestimate REE.

Abstract Objective The present study aimed to evaluate the effects of GH treatment on the body composition of children born with SGA. Methods This study is a systematic review of the literature. CINAHL, Embase; Medline/Pubmed, Scopus and Web of Science were searched from inception to March 2022. Results Four studies met the inclusion criteria, with an intervention time of 1 to 3 years, using doses from 0.03 to 0.07 mg/kg/day of GH. Bone densitometry by dual-energy X-ray absorptiometry (DXA) with whole-body scans was the most used method to assess body composition. Most studies (n= 3) had SGA children as a control group with the same characteristics as the case group; the mean age was similar between the groups (minimum of 5.1 ± 1.4 years and maximum of 6.7 ± 1 0.8 years) and all participants had an average height ≤ -3DP. The Lean Mass (LM) and Fat Mass (FM) outcomes of the studies were not presented in a standardized manner; thus, they cannot be compared. There was a significant increase in LM in the group treated with GH in relation to the pre-treatment period and in comparison, to the untreated control group. Three studies showed a significant decrease in FM at the end of the intervention period, and in two studies, this decrease occurred in the control group. Conclusions Despite the differences in the presentation of results and in the evaluation periods, the results of the studies showed that growth hormone favors the gain and maintenance of lean mass, and it also affects fat mass reduction and redistribution.
RESUMEN
Few data from Latin American centers on clinical outcomes in coronavirus disease 2019 (COVID-19) patients with acute respiratory distress syndrome who required extracorporeal membrane oxygenation (ECMO) are published. Moreover, clinical and functional status after hospital discharge remains poorly explored in these patients. We evaluated in-hospital outcomes of severe COVID-19 patients who received ECMO support in two Brazilian hospitals. In one-third of the survivors, post-acute COVID-19 syndrome (PACS), quality of life, anxiety, depression, and return to work were evaluated. Eighty-five patients were included and in-hospital mortality was 47%. Age >65 years (HR: 4.8; 95% confidence interval [CI]: 1.4-16.4), diabetes (HR: 6.0; 95% CI: 1.8-19.6), ECMO support duration (HR: 1.08; 95% CI: 1.05-1.12) and dialysis initiated after ECMO (HR: 3.4; 95% CI: 1.1-10.8) were independently associated with higher in-hospital mortality and mechanical ventilation (MV) duration before ECMO was not (HR: 1.18; 95% CI: 0.71-2.09). PACS-related symptoms were reported by two-thirds and half of patients at 30- and 90-days post-discharge, respectively. The median EQ-5D score was 0.85 (0.70-1.00) and 0.77 (0.66-1.00) at 30 and 90 days. Of the 15 responders, all previously working patients, except one, have returned to work at 90 days. In conclusion, in-hospital mortality in a large Latin American cohort was comparable to the Global extracorporeal life support organization registry.

Late leaf rust is a fungal disease in raspberries caused by Aculeastrum americanum (Farl.) M. Scholler U. Braun (syn. Thekopsora americana (Farl.) Aime McTaggart) leading to early defoliation and yield losses. Red raspberries (Rubus idaeus L.) are susceptible to this pathogen, although this susceptibility varies among cultivars. In contrast, black raspberries were previously reported to be more resistant (Rubus occidentalis L.) and immune (Rubus niveus Thunb.) to this pathogen, raising their importance in plant breeding programs. However, what features make them respond differently to the same pathogen? In this study, we characterize for the first time the pre- and post-formed structural and biochemical defense mechanisms of R. idaeus cv. Autumn Bliss, R. occidentalis and R. niveus. Ultrastructural and histopathological analyses were used to uncover the interactions between these raspberries and A. americanum. The ultrastructural results indicate that the pathogen germinates on both leaf surfaces but can only form appressoria on the stomata. Although the three raspberry species were infected and colonized by A. americanum, a clear difference in susceptibility was observed between them. A compact mesophyll, pre- and post-formed phenolic compounds, and post-formed pectic compounds were the main plant defense mechanisms against fungal colonization. These findings provide new information about raspberries' defense mechanisms in response to A. americanum and elucidate the interactions occurring in these pathosystems.
RESUMEN
Some extraintestinal pathogenic Escherichia coli isolates (ExPEC), obtained from humans and chickens avian pathogenic E. coli (APEC), share similar virulence genes. Thus, products of avian origin can be a source of human infection. Moreover, these APEC isolates are resistant to antimicrobials and can spread in the environment through the chicken feces. Although the development of multidrug-resistant (MDR) microorganisms in poultry is on the rise, healthcare entities have raised concerns since MDRs can horizontally transfer resistance genes to other microorganisms and complicate the management of human infections by MDR APEC. The results of our study showed that of 80 investigated spiced chicken meat samples, 55% were contaminated with E. coli, of which 34% (15/44) contaminate with APEC. No diarrheagenic E. coli (DEC) pathotypes were found. Twenty-six isolates were MDR E. coli. Among the APEC isolates, 87% (13/15) produced extended-spectrum beta-lactamase (ESBL). The emergence of MDR/ESBL-producing APEC with zoonotic potential for humans is extremely worrying. Therefore, further studies are required to identify the prevalence of MDR/ESBL-producing APEC in the entire chicken production chain from creation, slaughter, processing, and butchery.

Diagnostic histopathology plays a key role in the management of oral cancer and timely reports are essential. The aim of this study was to retrospectively compare the time interval between receipt of the specimen and issue of the histopathology report (the 'turnaround time', TT) of two types of oral cancer resections (mandibulectomies and glossectomies) and incisional biopsies from the tongue (n = 100 of each). The information documented included the number of days from receipt of the specimen until the sample was ready for reporting, and the number of subsequent days until the report was authorised by the pathologist. The number of days mandibulectomies required decalcification, the number of blocks processed per sample, and pathological TNM stage were also recorded. Results showed that mandibulectomies had statistically significantly longer TT than glossectomies. Incisional biopsies had the shortest TT with 87% reported in seven days and 95% in ten. There were also statistically significantly longer TT for pT3/pT4 than for pT1/pT2 glossectomies, and between the number of blocks processed for the three main groups. Decalcification and the interval whilst the slides awaited the pathologists' attention were identified as 'bottlenecks'. Dentate mandibulectomies had the longest TT of all; extraction of teeth at operation and detachment of the lower border of the mandible at macroscopic sampling are thus potential means by which the decalcification delay might be reduced. Expectations of the multidisciplinary team managing the patient should be realistic when scheduling postoperative discussion.

Mechanisms to sense and respond to pathogens have evolved in all species. The plant immune pathway is initiated by the activation of transmembrane receptor kinases that trigger phosphorylation relays resulting in cellular reprogramming. BOTRYTIS-INDUCED KINASE 1 (BIK1) is a direct substrate of multiple immune receptors in Arabidopsis thaliana and is a central regulator of plant immunity. Here, we review how BIK1 activity and protein stability are regulated by a dynamic interplay between phosphorylation and ubiquitination.

OBJECTIVE: To identify the dietary patterns and associated factors of children aged between 6 and 23 months, born prematurely and assisted at a University Hospital in Curitiba, state of Paraná, Brazil. METHODS: The parents or guardians of the 135 children were asked about their children's eating habits and the family's socioeconomic and demographic conditions. Information regarding birth and health history were obtained from medical records. Data on food consumption were subjected to exploratory factor analysis and the principal component analysis method was used to estimate the factor loads. Multiple linear regression was performed to verify possible associations. RESULTS: Two dietary patterns were observed: "unhealthy" and "healthy." The "unhealthy" pattern was significantly associated with maternal age, the child's corrected age, and gestational age at birth. The "healthy pattern" was associated with the child's corrected age. Maternal age and child's corrected age remained significant after multiple regression analyses. For the "unhealthy" pattern, a positive effect was observed, suggesting that the consumption of this pattern is higher as the child's age increases and less intense for children with mothers aged 30 years or older. For the "healthy" dietary pattern, the same two variables showed statistical significance. The authors observed a direct proportion between the age and consumption of food groups in both patterns. CONCLUSIONS: These results indicate the importance of nutritional education for younger mothers regarding their children's eating practices, especially as the child grows.

OBJECTIVE: To analyze the existing scientific literature to find out if the coronavirus disease 2019 (COVID-19) pandemic has an effect on gynecological health. SEARCH STRATEGY: We performed an integrative review of articles published between April 2020 and April 2021 on the PubMed, SciELO, and LILACS databases, using COVID-19 and the following relevant terms: Menstrual change; Ovarian function; Violence against women; Contraception; HPV; Mental health; and Urogynecology. SELECTION CRITERIA: Among the eligible studies found, editorials and primary research articles, which describe the dynamics between severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection (the cause of the COVID-19 pandemic) and gynecological health, were included. DATA COLLECTION AND ANALYSIS: Through qualitative synthesis, data were extracted from the included publications and from guidelines of national and international societies of gynecology. MAIN RESULTS: The 34 publications included in the present study showed that some factors of the SARS-CoV-2 infection, and, consequently, the COVID-19 pandemic, might be associated with menstrual abnormalities, effects on contraception, alterations in steroid hormones, changes in urogynecological care, effects on women's mental health, and negative impact on violence against women. CONCLUSION: The COVID-19 pandemic has significantly impacted the health of women. The scientific community encourages the development of recommendations for specialized care for women and strategies to prevent and respond to violence during and after the COVID-19 pandemic.
OBJETIVO: Analisar a literatura científica existente para saber se a pandemia de doença do coronavírus 2019 (coronavirus disease 2019, COVID-19, em inglês) afeta a saúde ginecológica. ESTRATéGIA DE PESQUISA: Realizou-se revisão integrativa de artigos publicados entre abril de 2020 e abril de 2021 nas bases de dados PubMed, SciELO e LILACS, utilizando COVID-19 e os seguintes termos: Menstrual change; Ovarian function; Violence against women; Contraception; HPV; Mental health; e Urogynecology. CRITéRIO DE SELEçãO: Entre os estudos elegíveis encontrados, foram incluídos editoriais e artigos de pesquisa que descrevem a dinâmica entre a infecção por coronavírus da síndrome respiratória aguda grave (severe acute respiratory syndrome coronavirus, SARS-CoV-2, em inglês), a causa da pandemia de COVID-19, e a saúde ginecológica. COLETA E ANáLISE DE DADOS: Por meio de síntese qualitativa, os dados foram extraídos das publicações incluídas e de diretrizes de sociedades nacionais e internacionais de ginecologia. RESULTADOS PRINCIPAIS: As 34 publicações incluídas no estudo mostraram que alguns fatores da infecção por SARS-CoV-2, e, consequentemente, da pandemia de COVID-19, podem estar associados a alterações menstruais, influências na contracepção, alterações em hormônios esteroides, adaptações na assistência uroginecológica, influência na saúde mental da mulher, e impacto negativo na violência contra a mulher. CONCLUSãO: A pandemia de COVID-19 teve um impacto significativo na saúde das mulheres. A comunidade científica incentiva o desenvolvimento de recomendações para o atendimento especializado a mulheres, e estratégias para prevenir e combater a violência durante e após a pandemia de COVID-19.
