RESUMO

The adaptive radiation of the angiosperms was strongly affected by fruit and seed dispersal since the establishment of the seedlings is a fundamental process for the recruitment of juveniles to the populations. Among the species of Burseraceae, seeds with fleshy attachments and high caloric value suggest mammaliochory as an ancestral dispersal way. In Protium icicariba, at the same time as there is a visual pattern typical of ornithochory, with a report of effective demonstration, the diaspores present the highest levels of essential oils of the whole plant, suggesting other dispersion processes by olfactory guided vectors. This work aims to monitor the diasporic dispersal process in P. icicariba in situ, aiming to identify dispersers and to investigate the role of the essential oil in the dispersion of diaspores of this plant species. The natural dispersion was monitored in situ, in weekly campaigns throughout eight months, using visual and photographic records, in daily shifts of six hours, distributed along the dawn, morning, afternoon, dusk, and night. We used both direct observation and continuous picture capturing along 43 days with photographic traps. Mature diaspores removed from pseudocapsules were pooled to determine potential dispersers. Artificial models of the diaspores, in white and green colors, were also used to test hypotheses on the role of scent in the dispersion, added 1%, weight/weight, of the essential oil extracted from the mature diaspores, which chemical composition determined by gas chromatography coupled to mass spectrometry. Besides, the analysis of stomach contents of lizards collected in adjacent area was also performed. In daytime and nighttime monitoring in nature, no vertebrates were recorded dispersing diaspores. The most common was the primary wind-facilitated autochory of diaspores to the substrate, near the plant matrices. Secondarily, workers of the ant species Atta robusta can remove the pseudoarils or move the pyrenes to the anthills. The lizard species Tropidurus torquatus ingests pyrenes with the pseudoarils, and the sclerified pericarp of the pyrene is potentially resistant to chemical action of the digestive juices. Ants and lizards have also accessed the caves with natural diaspores. Concerning the artificial diaspore models, ants accessed, indistinctly, white and the green models that contained essential oils. The lizards accessed the white models, with or without essential oils, and showed insignificant access to green ones, with or without essential oil. The ingestion of pyrenes by lizards was also confirmed through analysis of stomach contents. The aggregate spatial pattern of P. icicariba at the study site, associated with clumps, may be derived from germination in the substrate near the matrices, or in the anthills or after diaspora defecation and / or regurgitation of the lizard, which is a species strongly associated with clumps of this vegetation. As the access to the diaspores by ants and lizards depends on the primary autochory, and no impediments to the germination near to the matrix plant were found, the dispersion is compatible with a multifactorial characteristic of the diplochory.

RESUMO

BACKGROUND: Individuals receiving the human papillomavirus (HPV) vaccine develop high levels of circulating neutralizing antibodies. However, data about antibody responses in the cervix are limited. METHODS: This study was designed to describe the course of IgA/IgG responses in cervical secretions and in serum after intramuscular administration of the HPV16/18 AS04-adjuvant vaccine. An enzyme-linked immunosorbent assay for detection of IgA and IgG anti-HPV-VLP was developed for this purpose. RESULTS: Immunoglobulin G seroconversion after the second dose was observed in 100% of the participants and remained 1 month after the third dose. Regarding IgG reactivity in cervical secretions, conversion was observed in 85% of women after the final dose. Immunoglobulin A seroconversion was observed in 76.7% of women after the third dose. Lower levels of IgA were detected in the cervical mucus (28.3%) and decreased to 23.3% after the last dose. Comparing local and systemic IgG responses, positivity in both serum and cervical samples was observed in 85%, whereas in 15% only, the serum was IgG antibody positive. A weak agreement between local and systemic IgA responses was observed. Only 18.3% of participants were local and systemic IgA positive, 58.4% were positive only in serum, 5% were positive only in the cervix, and 18.3% were both local and systemic IgA antibody negative. CONCLUSIONS: After the third vaccination, there is a strong agreement between cervical and systemic IgG antibody responses and a weak agreement between cervical and systemic IgA antibody responses. The induction of IgA antibodies seems to be secondary to that of IgG antibodies in response to HPV intramuscular vaccination.

RESUMO

INTRODUCTION: The paediatric population represents a quarter of the world's population, and like adult patients, they have also suffered immeasurably from the SARS-CoV-2 pandemic. Immunisation is an effective strategy for reducing the number of COVID-19 cases. With the advancements in vaccination for younger age groups, parents or guardians have raised doubts and questions about adverse effects and the number of doses required. Therefore, systematic reviews focusing on this population are needed to consolidate evidence that can help in decision-making and clinical practice. This protocol aims to assess the safety of COVID-19 vaccines in paediatric patients and evaluate the correlation between the number of vaccine doses and side effects. METHODS AND ANALYSIS: We will search the PubMed, ClinicalTrials.gov, Web of Science, Embase, CINAHL, Latin American and Caribbean Health Sciences Literature, Scopus and Cochrane databases for randomised and quasi-randomised clinical trials that list the adverse effects of the COVID-19 vaccine and assess its correlation with the number of doses, without any language restrictions. Two reviewers will select the studies according to the inclusion and exclusion criteria, extract data and asses for risk of bias using the Cochrane risk-of-bias tool. The Review Software Manager (RevMan V.5.4.1) will be used to synthesise the data. We will use the Working Group's Grading of Recommendations Assessment, Development and Evaluations to grade the strength of the evidence of the results. ETHICS AND DISSEMINATION: Formal ethical approval is not required as no primary data are collected. This systematic review will be disseminated through a peer-reviewed publication. PROSPERO REGISTRATION NUMBER: CRD42023390077.

RESUMO

BACKGROUND: Energy-based devices (laser and radiofrequency) have been used to treat genitourinary syndrome of menopause (GSM). OBJECTIVES: To evaluate the efficacy and safety of physical energy use in managing GSM symptoms. SEARCH STRATEGY: Five databases were searched from inception to December 2022. Language restrictions were not imposed. SELECTION CRITERIA: We included all Cochrane and non-Cochrane systematic reviews with or without meta-analyses that described postmenopausal women with symptoms of GSM treated with physical energy. DATA COLLECTION AND ANALYSIS: We performed a network meta-analysis using frequentist methods to calculate standardized mean differences (SMDs) and their corresponding 95% confidence intervals (CIs). Methodological and reporting quality were assessed using the Assessment of Multiple Systematic Reviews (AMSTAR 2). MAIN RESULTS: Nine reviews were included in the overview, six of which were meta-analyses. Four randomized controlled trials, representing 218 participants and nine different study arms, met the criteria for inclusion in our component network meta-analysis. Confidence in review findings was low in six reviews and critically low in three. Our network meta-analysis results showed that premarin (SMD 2.60, 95% CI 7.76-3.43), conjugated estrogens (SMD 2.13, 95% CI 1.34-2.91), carbon dioxide laser (SMD 1.71, 95% CI 1.10-2.31), promestriene (SMD 1.41, 95% CI 0.59-2.24), and vaginal lubricant (SMD 1.37, 95% CI 0.54-2.20) were more effective than sham for reducing sexual dysfunction, with a consequent increase in Female Sexual Function Index (FSFI). Two studies showed a high risk of bias, owing to a lack of blinding. CONCLUSION: Several gaps in the use of physical energy for managing GSM still need to be addressed. The small number of blind clinical trials made the results fragile.

RESUMO

INTRODUCTION: Breast cancer survivors (BCSs) experience more severe symptoms of genitourinary syndrome of menopause (GSM) than healthy postmenopausal women. As hormonal therapy with oestrogen should be avoided in BCSs, finding an effective and safe therapy to address vaginal symptoms and sexual dysfunction is urgently needed. Physical methods may be promising alternatives for the specificities of this group of women. This review aims to evaluate the efficacy and safety of physical methods (laser and radiofrequency) for treating GSM in BCSs. METHODS AND ANALYSIS: The PubMed, Embase, Web of Science, SciELO, LILACS, Scopus, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov databases will be searched. A search strategy was developed to retrieve clinical trials that evaluate the efficacy and safety of any physical method (laser or radiofrequency) used for GSM in BCSs. No date or language restrictions will be imposed. Two authors will independently select studies by title, abstract and full text to meet the inclusion criteria. Data will be extracted, and the risk of bias will be evaluated using the Cochrane risk-of-bias tool (RoB 2). Review Manager 5.4.1 will be used for data synthesis. The Grading of Recommendations, Assessment, Development and Evaluation will be used to assess the strength of the evidence. ETHICS AND DISSEMINATION: This study reviews the published data; thus, obtaining ethical approval is unnecessary. The findings of this systematic review will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023387680.

RESUMO

OBJECTIVE: The objective of this study was to determine adverse maternal and perinatal outcomes in pregnant women with hypertensive disorders of pregnancy. METHODS: An analytical cross-sectional study was conducted on women admitted with hypertensive disorders of pregnancies to a university maternity hospital from August 2020 to August 2022. Data were collected using a pretested structured questionnaire. Variables associated with adverse maternal and perinatal outcomes were compared using multivariable binomial regression. RESULTS: Of 501 women with pregnancies, 2, 35, 14, and 49% had eclampsia, preeclampsia, chronic hypertension, and gestational hypertension, respectively. Women with preeclampsia/eclampsia had significantly higher risks of cesarean section (79.4 vs. 65%; adjusted RR, 2,139; 95%CI, 1,386-3,302; p=0.001) and preterm delivery at <34 weeks' gestation (20.5 vs. 6%; adjusted RR, 2.5; 95%CI, 1.19-5.25; p=0.01) than those of women with chronic/gestational hypertension. Risks of prolonged maternal hospitalization (43.9 vs. 27.1%), neonatal intensive care unit admission (30.7 vs. 19.8%), and perinatal mortality (23.5 vs. 11.2%) were higher among women with preeclampsia/eclampsia. CONCLUSIONS: Women with preeclampsia/eclampsia had a higher risk of adverse maternal and neonatal outcomes than those with chronic or gestational hypertension. This major maternity care center requires strategies for preventing and managing preeclampsia/eclampsia to improve pregnancy outcomes.

RESUMO

OBJECTIVE: To assess the efficacy, safety, and acceptability of misoprostol in the treatment of incomplete miscarriage. DATA SOURCES: The PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Clinical Trials databases (clinicaltrials.gov) were searched for the relevant articles, and search strategies were developed using a combination of thematic Medical Subject Headings terms and text words. The last search was conducted on July 4, 2022. No language restrictions were applied. SELECTION OF STUDIES: Randomized clinical trials with patients of gestational age up to 6/7 weeks with a diagnosis of incomplete abortion and who were managed with at least 1 of the 3 types of treatment studied were included. A total of 8,087 studies were screened. DATA COLLECTION: Data were synthesized using the statistical package Review Manager V.5.1 (The Cochrane Collaboration, Oxford, United Kingdom). For dichotomous outcomes, the odds ratio (OR) and 95% confidence interval (CI) were derived for each study. Heterogeneity between the trial results was evaluated using the standard test, I2 statistic. DATA SYNTHESIS: When comparing misoprostol with medical vacuum aspiration (MVA), the rate of complete abortion was higher in the MVA group (OR = 0.16; 95%CI = 0.07-0.36). Hemorrhage or heavy bleeding was more common in the misoprostol group (OR = 3.00; 95%CI = 1.96-4.59), but pain after treatment was more common in patients treated with MVA (OR = 0.65; 95%CI = 0.52-0.80). No statistically significant differences were observed in the general acceptability of the treatments. CONCLUSION: Misoprostol has been determined as a safe option with good acceptance by patients.


OBJETIVO: Avaliar a eficácia, segurança e aceitabilidade do misoprostol no tratamento do aborto incompleto. FONTES DE DADOS: Os bancos de dados PubMed, Scopus, Embase, Web of Science, Cochrane Library e bancos de dados de Ensaios Clínicos (clinicaltrials.gov) foram pesquisados para os artigos relevantes, e estratégias de busca foram desenvolvidas usando uma combinação de termos temáticos de Medical Subject Headings e palavras de texto. A última pesquisa foi realizada em 4 de julho de 2022. Nenhuma restrição de idioma foi aplicada. SELEçãO DOS ESTUDOS: Foram incluídos ensaios clínicos randomizados com pacientes com idade gestacional até 6/7 semanas com diagnóstico de aborto incompleto e que foram manejadas com pelo menos um dos três tipos de tratamento estudados. Um total de 8.087 estudos foram selecionados. COLETA DE DADOS: Os dados foram sintetizados usando o pacote estatístico Review Manager V.5.1 (The Cochrane Collaboration, Oxford, United Kingdom). Para resultados dicotômicos, o odds ratio (OR, na sigla em inglês) e o intervalo de confiança (IC) de 95% foram derivados para cada estudo. A heterogeneidade entre os resultados do ensaio foi avaliada usando o teste padrão, estatística I2. SíNTESE DOS DADOS: Ao comparar misoprostol com aspiração a vácuo médico (MVA, na sigla em inglês), a taxa de aborto completo foi maior no grupo MVA (OR = 0,16; IC95% = 0,07­0,36). Hemorragia ou sangramento intenso foi mais comum no grupo do misoprostol (OR = 3,00; 95%CI = 1,96­4,59), mas a dor após o tratamento foi mais comum em pacientes tratados com MVA (OR = 0,65; 95%CI = 0,52­0,80). Não foram observadas diferenças estatisticamente significativas na aceitabilidade geral dos tratamentos. CONCLUSãO: O misoprostol tem se mostrado uma opção segura e com boa aceitação pelos pacientes.

RESUMO

OBJECTIVE: To evaluate the efficacy of the hormonal and nonhormonal approaches to symptoms of sexual dysfunction and vaginal atrophy in postmenopausal women. DATA SOURCES: We conducted a search on the PubMed, Embase, Scopus, Web of Science, SciELO, the Cochrane Central Register of Controlled Trials (CENTRAL), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases, as well as on clinical trial databases. We analyzed studies published between 1996 and May 30, 2020. No language restrictions were applied. SELECTION OF STUDIES: We selected randomized clinical trials that evaluated the treatment of sexual dysfunction in postmenopausal women. DATA COLLECTION: Three authors (ACAS, APFC, and JL) reviewed each article based on its title and abstract. Relevant data were subsequently taken from the full-text article. Any discrepancies during the review were resolved by consensus between all the listed authors. DATA SYNTHESIS: A total of 55 studies were included in the systematic review. The approaches tested to treat sexual dysfunction were as follows: lubricants and moisturizers (18 studies); phytoestrogens (14 studies); dehydroepiandrosterone (DHEA; 8 studies); ospemifene (5 studies); vaginal testosterone (4 studies); pelvic floor muscle exercises (2 studies); oxytocin (2 studies); vaginal CO2 laser (2 studies); lidocaine (1 study); and vitamin E vaginal suppository (1 study). CONCLUSION: We identified literature that lacks coherence in terms of the proposed treatments and selected outcome measures. Despite the great diversity in treatment modalities and outcome measures, the present systematic review can shed light on potential targets for the treatment, which is deemed necessary for sexual dysfunction, assuming that most randomized trials were evaluated with a low risk of bias according to the Cochrane Collaboration risk of bias tool. The present review is registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42018100488).


OBJETIVO: Avaliar a eficácia das abordagens hormonais e não hormonais para os sintomas de disfunção sexual e atrofia vaginal em mulheres na pós-menopausa. FONTES DE DADOS: Pesquisamos as bases de dados PubMed, Embase, Scopus, Web of Science, SciELO, Cochrane Central Register of Controlled Trials (CENTRAL), e Cumulative Index to Nursing and Allied Health Literature (CINAHL), assim como bancos de dados de ensaios clínicos. Foram analisados estudos publicados entre 1996 e 30 de maio de 2020. Nenhuma restrição de idioma foi aplicada. SELEçãO DOS ESTUDOS: Foram selecionados ensaios clínicos randomizados que avaliavam o tratamento das disfunções sexuais em mulheres na pós-menopausa. COLETA DE DADOS: Três autores (ACAS, APFC e JL), revisaram cada artigo com base em seu título e resumo. Os dados relevantes foram posteriormente retirados do texto completo do artigo. Quaisquer discrepâncias durante a revisão foram resolvidas por consenso entre todos os autores listados. SíNTESE DOS DADOS: Ao todo, 55 estudos foram incluídos na revisão sistemática. As abordagens testadas para tratar a disfunção sexual foram: lubrificantes e hidratantes (18 estudos); fitoestrogênios (14 estudos); deidroepiandrosterona (DHEA; 8 estudos); ospemifeno (5 estudos); testosterona vaginal (4 estudos); exercícios para os músculos do assoalho pélvico (2 estudos); oxitocina (2 estudos); laser de CO2 vaginal (2 estudos); lidocaína (1 estudo), e vitamina E vaginal (1 estudo). CONCLUSãO: Identificou-se falta de coerência na literatura quanto aos tratamentos propostos e medidas de resultados selecionadas. Apesar da grande diversidade de modalidades de tratamento e medidas de resultados, esta revisão sistemática pode lançar luz sobre alvos potenciais para o tratamento, que é considerado necessário para a disfunção sexual, assumindo que a maioria dos estudos randomizados foi avaliada com baixo risco de viés de acordo com a ferramenta de avaliação de risco de viés de Cochrane Collaboration. Esta revisão tem cadastro no International Prospective Register of Systematic Reviews (PROSPERO; CRD42018100488).

RESUMO

INTRODUCTION: SARS-CoV-2 is responsible for a large number of global COVID-19 cases. Strategies such as social isolation, personal hygiene and frequent hand washing have been implemented; however, a protective vaccine is required to achieve sufficient herd immunity to SARS-CoV-2 infection to ultimately control the COVID-19 pandemic. To meet the urgent need for a vaccine, a reduction in the development schedule has been proposed from 10-15 years to 1-2 years. For this reason, this systematic review and meta-analysis protocol aims to compare the side effects, safety and toxicity of COVID-19 vaccines available globally, including their combinations. METHODS AND ANALYSIS: We will select randomised controlled trial-type studies that evaluate the side effects of the COVID-19 vaccine. PubMed, Web of Science, Embase, CINAHL, PsycINFO, LILACS, SCOPUS, ClinicalTrials.gov, International Clinical Trials Registry Platform (ICTRP), medRxiv.org, biorxiv.org, preprints.org and the Cochrane Library will be searched for eligible studies until December 2021. Three reviewers will independently screen and select studies, assess methodological quality and extract data. A meta-analysis will be performed, if possible, and the Grading of Recommendations, Assessment, Development and Evaluations summary of findings will be presented. ETHICS AND DISSEMINATION: This study will review published data, and thus it is unnecessary to obtain ethical approval. The findings of this systematic review will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42021231101.

RESUMO

BACKGROUND: Mechanical factors are primary complications that justify early removal of a peripherally inserted central catheter, and thrombotic catheter occlusion is the most critical mechanical complication associated with loss of device functionality. Studies have investigated these factors in adult patients, but findings are not directly applicable to newborns. Therefore, systematic reviews focusing on this population are necessary for consolidated evidence to aid clinical practice. AIMS: This study aims to evaluate the efficacy of intermittent heparin washing versus 0.9% sodium chloride solution for preventing occlusion in newborns with peripherally inserted central catheters. METHODS: We will use the PubMed, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, and Clinical Trial Databases for article search, without language or publication periods restrictions. Randomized clinical trials evaluating the use of intermittent heparin washing versus 0.9% sodium chloride solution in newborns with peripherally inserted central venous catheters will be included. The primary outcome will be peripherally inserted central catheter occlusion. Two reviewers will independently screen the studies, based on the inclusion criteria, extract the data for each included study and assess the risk of bias using the Cochrane risk of bias tool. The data will be synthesized using the Review Manager software (RevMan 5.4.1). To classify the strength of the evidence of results, we will use the Grading of Recommendations Assessment, Development and Evaluation Working Group (GRADE). The review was registered with PROSPERO (registration number CRD42021281509). EXPECTED RESULTS: We expect that this study would reveal the best method for preventing catheter occlusion in newborns with peripherally inserted central catheters.

RESUMO

INTRODUCTION: Menopause is a physiological and progressive phenomenon secondary to decreased ovarian follicular reserve. These changes have consequences: vaginal dryness, dyspareunia, discomfort, burning and irritation, vulvovaginal pruritus, dysuria and increased frequency of genitourinary infections. The therapy more suitable for vaginal symptoms in postmenopause yet is the use of a topical hormone. However, the prescription of topical oestrogens should also be avoided in women with a history of breast cancer, oestrogen-sensitive tumours and thromboembolism, emphasising the necessity of alternative treatments. Recently, physical methods, such as laser and radiofrequency (RF), in their non-ablative, ablative and microablative forms have been used in the vaginal mucosa to promote neocolagenesis and neoelastogenesis. This randomised study aims to compare the efficiency of microablative fractional RF (MAFRF) treatment with vaginal oestrogens and no treatment. METHODS AND ANALYSES: This randomised, controlled clinical intervention trial with an open label design comparing the treatment of MAFRF with vaginal oestrogens and no treatment. Four important moments were considered to evaluate treatment results (T0, T1, T2 and T3). The primary outcome includes vulvovaginal atrophy (vaginal pain, burning, itching, dryness, dyspareunia and dysuria), and the secondary outcomes will be sexual function, vaginal health (epithelial integrity, vaginal elasticity, moisture, fluid volume and vaginal pH) and quality of life. ETHICS AND DISSEMINATION: Due to the nature of the study, we obtained approval from the ethics committee. All participants must sign an informed consent form before randomisation. The results of this study will be published in peer-reviewed journals. The data collected will also be available in a public repository of data. TRIAL REGISTRATION NUMBER: RBR-94DX93.

RESUMO

Menopause is a physiological and progressive phenomenon secondary to decreased ovarian follicular reserve that significantly affects the genital tract. Although postmenopausal vulvovaginal atrophy primarily affects postmenopausal women, it is also seen in premenopausal women. The hypoestrogenic condition results in hormonal and anatomical changes, with the main symptoms, are dryness, burning and genital irritation, decreased lubrication, urinary urgency, dysuria, and recurrent urinary tract infections. This review aims to update hormone therapy for urogenital atrophy, both local and systemic, and discusses the importance of understanding and the need for active treatment of this condition. The main therapeutic objective is the relief of symptoms, and hormonal therapy (HT) is still the most effective choice for treating clinical manifestations, despite the side effects of its use. HT should be used in an individualized way to the needs of the women and appropriate to the stage in which she is menopausal, perimenopausal, or after menopause.

RESUMO

The estrogen decrease in postmenopausal women results in functional and anatomical changes in the genitourinary tract. The most prevalent and bothersome symptoms are vaginal dryness, dyspareunia, and reduced lubrication, which can significantly affect the quality of life of these women, principally those who are sexually active. Hormonal therapy with local estrogens is generally considered the "gold standard." However, there are cases in which there are clinical concerns about its use or women opt for non-hormonal options. Thus, safe and effective non-hormonal options are needed to improve symptoms in these women. Moisturizers and lubricants are first-line therapy for breast cancer survivors.

RESUMO

The genitourinary syndrome in menopause can occur at different stages of life, with different causes or triggering factors, such as prolonged use of antiestrogens, chemotherapy, radiotherapy, and extensive vaginal surgeries, which can alter vascularization, hydration, collagen quality, and tissue elasticity. Despite hormonal therapy being considered the best evidenced treatment for genitourinary syndrome of menopause (GSM), there are limitations concerning the latter. Thus, alternative, complementary, or even substitutive treatments have emerged, such as energy use, promoting thermal tissue stimulation to improve tropism. Due to its practicality and feasibility, the micro ablative fractional radiofrequency (MAFRF) has gained space among these energies. It uses high-frequency electromagnetic waves and promotes thermal micro points in the superficial and deep dermis. The safety of these energies limits thermal action laterality and depth. Laterally, it is essential for an adequate regenerative effect without scarring marks or sequelae; the appropriate depth is important for stimulating the obligatory tissue repair response with the production and reorganization of collagen, elastic fibers, increased vascularization and hydration, and the consequent improvement in tropism. In gynecology, the MAFRF is used with therapeutic indication and functional improvement; it is applied to the entire length of the vaginal walls, the vulvar vestibule, urethral meatus, labia minora, clitoris prepuce, labia majora, perineum, and perianal region. The MAFRF has been proved to be an effective and safe treatment for GSM, with long-lasting effects, significantly reducing symptoms and improving vaginal tropism. This review aims to analyze the MAFRF as a non-hormonal therapeutic option for GSM.

RESUMO

Genitourinary syndrome of menopause (GSM) is a term used to define a compilation of signs and symptoms arising from decreased estrogenic stimulation of the vulvovaginal and lower urinary tract. Among 27-84% of women in postmenopausal are affected for symptoms of GSM, and these can unquestionably impair health, sexual function, consequently the quality of life of these women. The main signs and symptoms of GSM include, among others, burning, irritation, vulvovaginal dryness, dyspareunia, urinary symptoms of urgency, dysuria, or recurrent urinary tract infection. The diagnosis can be made through anamnesis, questionnaires, physical exams, and, sometimes, complementary exams. Objective vaginal assessment is essential and can be complemented by using the Vaginal Health Index (VHI), Vaginal Maturation Index (VMI), or vaginal pH measurement. The acknowledgment of this condition by health professionals is crucial for its identification and proper management and exclusion of other conditions that make a differential diagnosis with it.

RESUMO

BACKGROUND: Although much has been studied about the SARS-Cov-2 virus, its effects, and the effectiveness of possible treatments, little is known about its interaction with other infectious diseases. OBJECTIVE: The aim is to study its clinical features and morbidity, and mortality outcomes of COVID-19 patients with HIV/AIDS coinfection. DATA SOURCES: MEDLINE, Web of Science, Embase, CINAHL, LILACS, Scopus, ClinicalTrials.gov, and Cochrane. STUDY ELIGIBILITY CRITERIA: Atudies in any language, published after 2019, were describing COVID-19 patients with HIV/AIDS. STUDY APPRAISAL: JBI Levels of Evidence, Joanna Briggs Institute. SYNTHESIS METHODS: As shown in the PRISMA flow diagram, two authors separately screened the search results from the obtained titles and abstracts. RESULTS: Chest CT was observed in patients with pneumonia by SARS-CoV-2 with findings of multiple ground-glass opacities (GGO) in the lungs, there is a need for supplemental oxygenation. One patient developed encephalopathy and complicated tonic-clonic seizures; four patients were transplanted (two, liver; two, kidneys), one patient developed severe SARS-CoV-2 pneumonia and 30 patients died (mortality rate, 11%). CONCLUSION: HIV did not show any relevance directly with the occurrence of COVID-19. Some studies suggest that HIV-1 infection through induction levels of IFN-I, may to some extent, stop the apparent SARS-CoV-2 infection, thus leading to undetectable RNA. Moreover, some authors suggest retroviral therapy routinely used to control HIV infection could be used to prevent COVID-19 infection.

RESUMO

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can affect the nervous system, triggering problems such as the Guillain-Barre Syndrome (GBS), an association that can bring complications to the patient. OBJECTIVE: This scoping review aimed to clarify the clinical features and analyze patients with GBS associated with SARS-CoV-2 infection, looking at morbidity, mortality, and neurological outcomes. SEARCH STRATEGY: The search was conducted through Medline, Web of Science, Embase, CINAHAL, Latin-American and Caribbean Literature in Health Sciences (LILACS), clinicaltrials.gov, SCOPUS, and the Cochrane Central Register of Controlled Trials. SELECTION CRITERIA: Observational studies, published after 2019, describe patients with GBS associated with SARS-CoV-2 infection. There were no language restrictions while selecting the studies. DATA COLLECTION AND ANALYSIS: Three authors, Kleyton Santos de Medeiros, Luíza Thomé de Araújo Macêdo, and Wederson Farias de Souza, independently screened the search results using titles and abstracts. Duplicate studies were excluded. The same authors then went through the entire text to determine whether the studies met the inclusion criteria. Discrepancies were resolved by other reviewers, Ana Paula Ferreira Costa, Ayane Cristine Sarmento, and Ana Katherine Gonçalves. Finally, the selection of the studies was summarized in a PRISMA flow diagram. MAIN RESULTS: Main manifestations were fever, coughing, dyspnea, sore throat, ageusia, anosmia, and respiratory failure, in addition to paresthesia of the upper and lower limbs, tetraparesis, facial diplegia, areflexia, asthenia, mastoid pain, acute ataxia, fatigue, numbness, swallowing disorder, and moderate low back pain. CONCLUSION: Coronavirus disease 2019 (COVID-19) can trigger the GBS, despite the few studies on this topic. Patients had clinical manifestations of COVID-19 infection and neurological manifestations characterizing GBS.

RESUMO

Laser therapy has been proposed to improve the symptoms of genitourinary syndrome of menopause (GSM), especially in women who do not accept hormonal therapy or are at a high risk of complications if they undergo hormonal therapy. However, studies evaluating the effectiveness and safety of laser treatment for GSM have shown controversial results. Thus, we aimed to determine the efficacy and safety of laser therapy in post-menopausal women with GSM. We have developed a protocol according to the Preferred Reporting Items for Systematic Review and Meta-analysis Protocol using the population, intervention, comparison, outcome, and study design (PICOS) framework for post-menopausal women who have received no treatment, laser therapy, placebo, or vaginal estrogen for GSM. As per our protocol, randomized controlled trials and quasi-randomized trials, regardless of language of publication, will be searched in PubMed, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, and clinicaltrials.gov. Gray literature will be searched in Open Gray and Google Scholar. The reference lists will be scanned for additional trials, and the authors will be contacted if necessary. Outcome data reported in a trial registry, even when no published results were available, will be analyzed. The search will be performed using key terms, such as "post-menopausal women," "menopausal genitourinary syndrome," "vulvovaginal atrophy," and "laser therapy." Two review authors will independently screen the titles and abstracts, while three others will independently evaluate the full text of each study to determine its eligibility for this systematic review (SR). Any disagreement will be resolved through discussion and consensus. Data extraction will be performed independently using a standardized data collection form. Clinical outcomes, including vaginal atrophy, vaginal pH, dryness, dyspareunia, itching, burning, dysuria, urinary frequency, urinary urgency, and urinary incontinence, will be systematically evaluated. We will not perform a separate search for adverse effects; instead, we will consider the adverse effects described in the included studies. Furthermore, we will summarize the effects of dichotomous outcomes as risk ratios with 95% confidence intervals. On the other hand, continuous outcomes will be summarized by expressing treatment effects as a mean difference with standard deviation or as a standardized mean difference when different scales were used to measure the same outcome. We will use the Cochrane Risk of Bias 2 tool for bias assessment and the Grading of Recommendations Assessment, Development and Evaluation approach to rate the overall certainty of evidence. Review Manager 5.3.5 will be used for quantitative data synthesis, subgroup analysis, sensitivity analysis, meta-regression, and risk of bias assessment. The SR findings will provide highly relevant evidence through the synthesis of well-designed and robust clinical trials on the effectiveness and safety of laser therapy in GSM. The Prospective Register of Systematic Reviews (PROSPERO) registration number (2021) of the SR is CRD42021253605.

RESUMO

INTRODUCTION: Therapeutic management of neonatal pain is essential to reduce changes in initial and subsequent development. Although glucose has been shown to be effective in relieving pain, concentrations and dosages remain to be standardised. The objective of this systematic review and meta-analysis is to identify the efficacy of glucose as an analgesic in preterm infants. METHODS AND ANALYSIS: The Web of Science, Science Direct, Scopus, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, PubMed, Medline, Latin American and Caribbean Health Sciences Literature and Embase databases will be researched for randomised studies published until December 2021. This systematic review and meta-analysis will include studies investigating the use of glucose for pain control in premature neonates. The primary outcome will be pain relief. Three independent reviewers will select the studies and extract the data from original publications. The risk of bias was assessed using the Cochrane risk of bias tool. Data synthesis will be performed using the Review Manager software (RevMan V.5.2.3). We will evaluate heterogeneity based on I2 statistics. In addition, quantitative synthesis will be performed if the included studies are sufficiently homogeneous. ETHICS AND DISSEMINATION: Ethical approval for the research will not be required for this systematic review. The results of this study will be published in an international journal. TRIAL REGISTRATION NUMBER: This protocol was submitted to the International Prospective Register of Systematic Reviews (PROSPERO, number CRD42021236217).

RESUMO

INTRODUCTION: Studies carried out during previous pandemics revealed an increase in the prevalence of Burnout Syndrome and other psychiatric disorders among health professionals. A high prevalence of psychiatric disorders is also observed in some health categories, during the COVID-19 pandemic. OBJECTIVE: This systematic review/meta-analysis study aims to assess the prevalence of Burnout Syndrome and other psychiatric disorders (depression, anxiety, stress, and insomnia) among health care professionals and other support professionals during the COVID-19 pandemic. INCLUSION CRITERIA: Observational studies published from December 2019, without language restrictions in which the prevalence of Burnout Syndrome and other psychiatric disorders among health professionals during the COVID-19 pandemic will be assessed. METHODS: PubMed, Web of Science, Embase, CINAHAL, PsycINFO, LILACS, SCOPUS, and The Cochrane Library will be searched for eligible studies. Two reviewers will independently screen and select studies, assess methodological quality, and extract data. A meta-analysis will be performed, if possible, and the Grading of Recommendations Assessment Development and Evaluation (GRADE). ETHICS AND DISCLOSURE: This study will use secondary data. Thus, there is no need for submission to the ethics committee. The results of this systematic review will be published in a journal after a peer-review process. TRIAL REGISTRATION: Systematic review registration number: CRD42020212036.
