BACKGROUND: The long-term impact of hospitalization for COVID-19 on patients' physical, mental, and cognitive health still needs further assessment. OBJECTIVES: This study aims to evaluate factors associated with quality of life and cardiovascular and non-cardiovascular outcomes 12 months after hospitalization for COVID-19. METHODS: This prospective multicenter study intends to enroll 611 patients hospitalized due to COVID-19 (NCT05165979). Centralized telephone interviews are scheduled to occur at three, six, nine, and 12 months after hospital discharge. The primary endpoint is defined as the health-related quality-of-life utility score assessed by the EuroQol-5D-3L (EQ-5D-3L) questionnaire at 12 months. Secondary endpoints are defined as the EQ-5D-3L at three, six and nine months, return to work or education, persistent symptoms, new disabilities in instrumental activities of daily living, cognitive impairment, anxiety, depression, and post-traumatic stress symptoms, major cardiovascular events, rehospitalization, as well as all-cause mortality at 3, 6, 9, and 12 months after SARS-CoV-2 infection. A p-value <0.05 will be assumed as statistically significant for all analyses. RESULTS: The primary endpoint will be presented as the frequency of the EQ-5D-3L score 12 months after COVID-19 hospitalization. A sub-analysis to identify possible associations of independent variables with study outcomes will be presented. CONCLUSIONS: This study will determine the impact of COVID-19 on the quality of life and cardiovascular and non-cardiovascular outcomes of hospitalized patients 12 months after discharge providing insights to the public health system in Brazil.

A Importância dos Métodos de Determinação das Idades Esquelética e Dentária na Ortodontia e Odontopediatria ­ uma Revisão de Literatura / The Importance of Methods for Determination of Squeletal and Dental Age in Orthodontics and Pediatric Dentistry ­ a Literature Review

O estágio de desenvolvimento humano é intimamente relacionado à sua maturidade óssea ou dentária, sendo essencial para a escolha do tratamento de alterações dentofaciais em crianças e adolescentes por ortodontistas e odontopediatras. Existem diversos indicadores biológicos para determinar a maturação do indivíduo, como a idade cronológica e as alterações hormonais, porém esses indicadores podem sofrer interferências. Visando uma determinação de desenvolvimento e dos picos de crescimento mais precisa, para um melhor diagnóstico e plano de tratamento, foram desenvolvidos diversos métodos para determinar a idade esquelética e a idade dentária, sendo estes a avaliação da maturação carpal, da morfologia das vértebras cervicais, da fusão óssea da sincondrose esfeno-occipital e da sutura palatina mediana, bem como dos estágios da calcificação dentária. A avaliação das radiografias de mão e punho é o padrão ouro da predição da idade esquelética, e sua correlação com outros métodos já é evidente. Sendo assim, é possível utilizar a avaliação das vértebras cervicais e das idades dentárias de Nolla e Demirjian.

The stage of human development is closely related to bone or dental maturity, being essential for the choice of treatment for dentofacial changes in children and adolescents by orthodontists and pediatric dentists. There are several biological indicators to determine an individual's maturation, such as chronological age and hormonal changes, but these indicators can suffer interference. Aiming at a more accurate determination of development and growth peaks, for a better diagnosis and treatment plan, several methods have been developed to determine skeletal age and dental age, these being the assessment of carpal maturation, the morphology of the cervical vertebrae, bone fusion of the spheno-occipital synchondrosis and the median palatal suture, as well as the stages of dental calcification. The evaluation of hand and wrist radiographs is the gold standard for predicting skeletal age, and its correlation with other methods is already evident. Therefore, it is possible to use the assessment of cervical vertebrae and dental ages by Nolla and Demirjian.

Relação entre desmame precoce, desenvolvimento de hábitos bucais deletérios e maloclusões na infância / Relationship between early weaning, development of harmful oral habits and malocclusions in childhood

Objetivo: o objetivo desta pesquisa foi analisar a associação do tempo de aleitamento materno com a prática de hábitos deletérios e o desenvolvimento de maloclusões na primeira infância. Materiais e Métodos: foram aplicados 171 formulários às mães com 18 anos ou mais que acompanharam o processo de amamentação de seu(s) filho(s) de 4 a 10 anos de idade. O questionário foi composto por 22 perguntas, sendo 15 específicas e relacionadas ao aleitamento, hábitos deletérios da criança (uso de chupeta, sucção de dedo e sucção do próprio lábio) e maloclusões específicas (mordida cruzada posterior, mordida cruzada anterior e mordida aberta). Resultados: a prevalência da amamentação exclusiva por 6 meses ou mais foi de 52%, enquanto 29,8% das crianças foram amamentadas de 0 a 5 meses e 18,2% nunca foram amamentadas no seio exclusivamente. Quanto a alimentação complementar, grande parcela (37,4%) encontrada evidenciou início após os 6 meses; 57,9% das mães relataram algum tipo de dificuldade para amamentar e 34,5% das crianças fizeram uso de chupeta. Em relação aos hábitos deletérios, 10% desenvolveram sucção de dedo. O relato de desenvolvimento de maloclusões foi de 9,4% das crianças com mordida cruzada posterior; 7,6% mordida cruzada anterior e 18,7% mordida aberta anterior. Conclusão: sendo assim, é possível inferir que o tempo preconizado pela Organização Mundial da Saúde para aleitamento materno exclusivo foi fundamental para o não desenvolvimento de hábitos deletérios e maloclusões. Em contrapartida, quanto mais cedo a introdução de alimentos complementares, e a interrupção do aleitamento exclusivo nos seis primeiros meses, maior o risco do desenvolvimento de hábitos e consequentemente maloclusões.

Objective: the objective of this research was to analyze the association of breastfeeding duration with the practice of deleterious habits and the development of malocclusions in early childhood. Materials and Methods: a total of 171 forms were applied to mothers aged 18 years or older who followed the breastfeeding process of their child(ren) between 4 and 10 years of age. The questionnaire consisted of 22 questions, 15 of which were specific and related to breastfeeding, the child's deleterious habits (use of a pacifier, finger sucking and lip sucking) and specific malocclusions (posterior crossbite, anterior crossbite and open bite). Results: the prevalence of exclusive breastfeeding for 6 months or more was 52%, while 29.8% of children were breastfed from 0 to 5 months and 18.2% were never exclusively breastfed. As for complementary feeding, a large portion (37.4%) found to start after 6 months; 57.9% of the mothers reported some type of difficulty in breastfeeding and 34.5% of the children used a pacifier. Regarding deleterious habits, 10% developed finger sucking. The report of development of malocclusions was 9.4% of children with posterior crossbite; 7.6% anterior crossbite and 18.7% anterior open bite. Conclusion: therefore, it is possible to infer that the time recommended by the World Health Organization for exclusive breastfeeding was fundamental for the non-development of deleterious habits and malocclusions. On the other hand, the earlier the introduction of complementary foods and the interruption of exclusive breastfeeding in the first six months, the greater the risk of developing habits and, consequently, malocclusions.

Serious lesions in Green turtles (Chelonia mydas) afflicted by fatal Spirorchiidiasis found stranded in south and southeastern Brazil.

Several diseases have been reported as affecting endangered wild sea turtle population worldwide, including spirorchiidiasis. This parasitic infection results in serious circulatory disorders in sea turtles, as well as tissue damage due to the presence of spirorchiids eggs. However, few reports of organs severely affected by tissue replacement caused by granulomatous inflammatory processes due to spirorchiidiasis in sea turtles are available. In this regard, this study describes massive lesions in 16 juvenile green turtles from southeastern Brazil presenting no other detectable diseases or injuries, associated to parasitic compression of air spaces, parasitic thyroid atrophy, parasitic encephalic compression and parasitic splenic lymphoid depletion. These rare injuries were categorized as extremely severe, affecting most spirorchiidiasis-infected organs. Spirorchiidiasis was, thus, noted herein as capable of causing a variety of lethal injuries to vital or extremely important organs in sea turtles. Spirorchiidiasis should, therefore, also be considered a potential cause of death in stranded green sea turtle monitoring efforts.

Modulation of miR-429 during osmotic stress in the silverside Odontesthes humensis.

Silverside fish inhabit marine coastal waters, coastal lagoons, and estuarine regions in southern South America. Although silversides are not fully adapted to freshwater, they can tolerate a wide range of salinity variations. MicroRNAs (miRNAs) are a class of ∼22 nucleotide noncoding RNAs, which are crucial regulators of gene expression at post-transcriptional level. Current data indicate that miRNAs biogenesis is altered by situations of environmental stress, thereby altering the expression of target mRNAs. Foremost, the silversides were acutely exposed to 30 g.L-1 of salt to reveal in which tissue miR-429 could be differentially expressed. Thus, fish were acclimated to freshwater (0 g.L-1) and to brackish water (10 g.L-1), and then exposed to opposite salinity treatment. Here, we reveal that miR-429, a gill-enriched miRNA, emerges as a prime osmoregulator in silversides. Taken together, our findings suggest that miR-429 is an endogenous regulator of osmotic stress, which may be developed as a biomarker to assist silverside aquaculture.

Using Qualitative Synthesis to Explore Heterogeneity of Randomized Trials on ICU Diaries.

OBJECTIVE: We aimed to identify which set of components differentiates the ICU diaries that were effective in reducing psychologic symptoms after critical illness. DATA SOURCES: We searched the online databases MEDLINE, OVID, Embase, and EBSCOhost from inception to December 2021. STUDY SELECTION: Randomized controlled trials (RCTs) of the ICU diary were included, irrespective of the language, with samples of adult patients (≥ 18 yr old) and/or their relatives hospitalized in an ICU for more than 24 hours. Two qualitative syntheses on patients' and healthcare providers' perceptions on the ICU diary were included. DATA EXTRACTION: Four findings were extracted from the qualitative synthesis of patients' perspectives on the ICU diary. From the RCTs, we extracted the components of the ICU diary and whether the patients were ventilated for at least 3 days. We reported the outcome as effective or not, regardless of the psychiatric symptoms and diagnostic tools used for evaluation. We built a matrix in which each column represented a recommendation for an intervention component derived from the qualitative review, and each row represented whether the components of an individual trial's intervention matched any of the recommendations. DATA SYNTHESIS: Eight RCTs were included in the final analysis. The sample of five studies consisted of patients under mechanical ventilation (MV) for at least 3 days. Two were positive trials. Three RCTs included family members, and two of those were positive trials. CONCLUSIONS: For patients under MV for at least 3 days, the ICU diaries that were effective in preventing psychiatric symptoms after critical illness were written by the ICU staff, delivered after hospital discharge, and read with a healthcare professional in order to better understand the diary and the ICU stay. For family members, the presence of photographs was the only characteristic identified a successful ICU diary.

Sleep in Paralympic athletes and its relationship with injuries and illnesses.

OBJECTIVES: To evaluate sleep characteristics and investigate the relationship of sleep with injuries and illnesses in Paralympic athletes. DESIGN: Cross-sectional. SETTING: Sports Training Center. PARTICIPANTS: 20 Paralympic athletes of athletics, swimming, and powerlifting. OUTCOMES: Injury and illnesses were recorded during the sports season through the Oslo Sports Trauma Research Center questionnaire (OSTRC-BR). Sleep-wake pattern was monitored for 2 weeks using actigraphy. Chronotype, sleep quality, sleep behavior, and sleep complaints were cross-sectionally collected. RESULTS: Poor sleep quality and poor sleep behavior were highly prevalent. The mean total sleep time was 6.57 ± 49.91. Duration of naps (r= -0.46; p=0.04) was associated with occurrence of health problems; frequency of insomnia (r= 0.51; p= 0.02), Pittsburgh Sleep Quality Index score (r= 0.45; p=0.04), and frequency of awakenings at night (r= 0.58; p= 0.01) were associated with severity of health problems; frequency of movements during sleep was associated with OSTRC-BR cumulative score (r= 0.58; p=0.00); and frequency of nightmares was associated with OSTRC mean score. CONCLUSIONS: Paralympic athletes tend to report poor sleep quality, have poor sleep behavior and sleep less than the recommended. Insomnia symptoms, awakenings at night, movements during sleep and poor sleep quality were associated with the occurrence and/or severity of health problems.

A clinical approach to managing open-bite malocclusion associated with severe crowding.

Open bite has been identified as one of the most challenging malocclusions in orthodontics. The treatment approach is complex, the resulting esthetics may not meet the patient's expectations, and the chance of recurrence is high. A 13-year-old girl presented a skeletal Class II malocclusion associated with anterior and posterior open bite, maxillary transverse deficiency, severe anterior crowding, and a hyperdivergent facial pattern. Orthodontic treatment was performed with a Haas expander and subsequent standard edgewise appliances, and the 4 first premolars were extracted. The vertical control of facial growth was undertaken with vertical pull chincap therapy, mini-implants associated with a titanium-molybdenum alloy cantilever on the right and left buccal sides, and a stainless steel alloy transpalatal arch. Posttreatment records showed a bilateral Class I molar relationship, ideal overbite and overjet, and improved facial profile and gingival health. The cephalometric analysis revealed a good balance of the skeletal pattern and facial profile, with an appropriate inclination of the maxillary and mandibular incisors. After a 7-year retention period, the outcome was pleasant facial esthetics and smile and stability of the dental occlusion. This case shows that the clinical approach was adequate, with treatment outcomes achieving positive aspects of function, esthetics, and stability.

Is there a correlation between dental and cervical vertebrae maturation stages in growing subjects? A systematic review with meta-analysis.

OBJECTIVE: To assess the evidence on the relationship between dental and cervical vertebrae maturation. MATERIALS AND METHODS: Searches were performed (up to December 2021) in seven databases, as well as in gray literature. Studies that included growing subjects, which evaluated the correlation between the stages of tooth formation and the maturation of cervical vertebrae, were eligible. The methodological quality of the selected reports was assessed using the JBI checklist for cross-sectional studies. Random-effects meta-analyses were implemented to calculate the pooled correlation coefficients between the maturation stages of cervical vertebrae and each tooth type. The GRADE approach was followed to assess the certainty of evidence. RESULTS: Seventy-seven studies were selected. Most of them had limitations related to sampling and reliability of the methods to evaluate maturation. The syntheses evidenced positive correlations between the maturation of cervical vertebrae and the formation/calcification stages of the following lower teeth: canine (n = 7318; r = 0.692; 95% CI: 0.656-0.724), first premolar (n = 6194; r = 0.689; 95% CI: 0.649-0.725), second premolar (n = 6194; r = 0.695; 95% CI: 0.659-0.729), and second molar (n = 7905; r = 0.698; 95% CI: 0.652-0.739). All estimates were affected by the risk of bias and the presence of unexplained statistical heterogeneity. CONCLUSIONS: The evidence points to an apparent positive correlation between dental and cervical vertebrae maturation. These results need to be carefully evaluated as the body of evidence is of very low quality. CLINICAL RELEVANCE: Dental maturation might be a potential indicator of skeletal craniofacial growth status. A routine dental x-ray could be sufficient, reducing radiation exposure by requesting additional radiographs.

Practices in sedation, analgesia, mobilization, delirium, and sleep deprivation in adult intensive care units (SAMDS-ICU): an international survey before and during the COVID-19 pandemic.

BACKGROUND: Since the publication of the 2018 Clinical Guidelines about sedation, analgesia, delirium, mobilization, and sleep deprivation in critically ill patients, no evaluation and adequacy assessment of these recommendations were studied in an international context. This survey aimed to investigate these current practices and if the COVID-19 pandemic has changed them. METHODS: This study was an open multinational electronic survey directed to physicians working in adult intensive care units (ICUs), which was performed in two steps: before and during the COVID-19 pandemic. RESULTS: We analyzed 1768 questionnaires and 1539 (87%) were complete. Before the COVID-19 pandemic, we received 1476 questionnaires and 292 were submitted later. The following practices were observed before the pandemic: the Visual Analog Scale (VAS) (61.5%), the Behavioral Pain Scale (BPS) (48.2%), the Richmond Agitation Sedation Scale (RASS) (76.6%), and the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) (66.6%) were the most frequently tools used to assess pain, sedation level, and delirium, respectively; midazolam and fentanyl were the most frequently used drugs for inducing sedation and analgesia (84.8% and 78.3%, respectively), whereas haloperidol (68.8%) and atypical antipsychotics (69.4%) were the most prescribed drugs for delirium treatment; some physicians regularly prescribed drugs to induce sleep (19.1%) or ordered mechanical restraints as part of their routine (6.2%) for patients on mechanical ventilation; non-pharmacological strategies were frequently applied for pain, delirium, and sleep deprivation management. During the COVID-19 pandemic, the intensive care specialty was independently associated with best practices. Moreover, the mechanical ventilation rate was higher, patients received sedation more often (94% versus 86.1%, p < 0.001) and sedation goals were discussed more frequently in daily rounds. Morphine was the main drug used for analgesia (77.2%), and some sedative drugs, such as midazolam, propofol, ketamine and quetiapine, were used more frequently. CONCLUSIONS: Most sedation, analgesia and delirium practices were comparable before and during the COVID-19 pandemic. During the pandemic, the intensive care specialty was a variable that was independently associated with the best practices. Although many findings are in accordance with evidence-based recommendations, some practices still need improvement.

Effectiveness of combined non-pharmacological interventions in the prevention of delirium in critically ill patients: A randomized clinical trial.

PURPOSE: Delirium is a common dysfunction in the intensive care unit (ICU) and it is associated with negative short- and long-term outcomes. This study evaluated the effectiveness of combined non-pharmacological interventions in preventing delirium in critically ill patients. MATERIALS AND METHODS: This is a single-center randomized controlled trial conducted in three Brazilian ICUs from February to September 2019. Patients assigned to the control group received standard care (n = 72) and those assigned to the experimental group (n = 72) received a bundle of non-pharmacological interventions (periodic reorientation, cognitive stimulation, correction of sensory deficits [visual or hearing impairment], environmental management and sleep promotion) throughout the ICU stay. Delirium was monitored twice a day with the Confusion Assessment Method for the Intensive Care Unit Flowsheet. The primary outcome was the incidence density of delirium. RESULTS: The incidence density of delirium was lower in the intervention group (1.3 × 10-2 person-days) than in the control group (2.3 × 10-2 person-days), with a hazard ratio of 0.40 (95% confidence intervals, 0.17-0.95; p = 0.04) after adjustment for Simplified Acute Physiology Score III, surgical admission and alcoholism. CONCLUSIONS: Combined non-pharmacological interventions reduced delirium in critically ill patients, compared to standard care.

Alinhadores Ortodônticos Removíveis Versus Aparelhos Ortodônticos Fixos: uma Revisão da Literatura / Removable Orthodontic Aligners Versus Fixed Orthodontic Appliances: a Literarture Review

Com intuito de pontuar os paralelos entre as técnicas ortodônticas com aparelhagem fixa e alinhadores transparentes, este estudo propôs revisar a literatura científica sobre alinhadores ortodônticos removíveis versus aparelhos ortodônticos fixos. Foram selecionados artigos de 2005 a 2021, utilizando as bases de dados PubMed, Scopus, Web of Science, Cochrane Library, Clinical Trials e Opengrey. Os artigos abordavam temáticas como sensação dolorosa, saúde periodontal, higiene, microbiota, reabsorção radicular, qualidade de vida e efetividade do tratamento. Os alinhadores apresentaram maior aceitabilidade pelos pacientes e vantagens claras em relação à dor, higiene, qualidade de vida, reabsorção radicular e saúde periodontal, sendo inferior aos aparelhos ortodônticos fixos na efetividade do tratamento e na interferência na fala.

In order to point out the parallels between orthodontic techniques with fixed appliances and transparent aligners, this study proposed to review the scientific literature on removable orthodontic aligners versus fixed orthodontic appliances. Articles from 2005 to 2021 were selected, using the PubMed, Scopus, Web of Science, Cochrane Library, Clinical Trials and OpenGrey databases. The articles addressed issues such as pain, periodontal health, hygiene, microbiota, root resorption, quality of life and treatment effectiveness. Aligners showed greater acceptability by patients and clear advantages in relation to pain, hygiene, quality of life, root resorption and periodontal health, being inferior to fixed orthodontic appliances in terms of effectiveness and speech capacity.

Exploring family members' and health care professionals' perceptions on ICU diaries: a systematic review and qualitative data synthesis.

PURPOSE: Although the intensive care unit (ICU) diary has been proposed as a tool for preventing psychiatric symptoms in survivors of critical illness, relatives and health care providers may benefit from it too. This study aims to summarize the current qualitative evidence on families' and health care professionals' experiences of writing in and reading the ICU diaries. METHODS: We searched MEDLINE, OVID, Embase, and EBSCOhost from inception to February 2021, and included all the studies that presented any qualitative finding regarding relatives' and health care providers' experiences of writing in and reading an ICU diary. We used modified Critical Appraisal Skills Programme (CASP) and Confidence in the Evidence from Reviews of Qualitative Research (CERQual) for quality assessment. A thematic synthesis approach was used to analyze and synthesize the qualitative data. RESULTS: Twenty-eight studies were analyzed (15 including family members and 13 including health care professionals). For family members, the ICU diary is an important source of medical information, provides a way for them to register their presence at patient's bedside and express their feelings, and contributes to humanizing the ICU staff. This impression is shared by relatives of patients who did not survive critical illness. Health care providers believe the diary is beneficial for themselves and others; however, they are concerned with possible negative impressions from patients and family that could lead to judicial problems. They also remark on several obstacles they face when constructing the diaries (workload, creativity, and environment for writing), which can make it a distressful process. CONCLUSION: This qualitative synthesis shows that family members and health care professionals consider the ICU diary a valuable intervention. It also brings evidence to challenges faced during diary writing, which should be carefully approached in order to reduce the stress associated with this process.

Exploring Patients' Perceptions on ICU Diaries: A Systematic Review and Qualitative Data Synthesis.

OBJECTIVES: This study aims to summarize the current qualitative evidence on patients' experiences of reading the ICU diaries. DATA SOURCES: We searched the online databases PubMed, Ovid, EMBASE, and EBSCO host from inception to July 2020. STUDY SELECTION: All studies that presented any qualitative findings regarding patients' experiences of reading an ICU diary were included. DATA EXTRACTION: Study design, location, publication year, data collection method, and mode, all qualitative themes identified and reported, and participant quotations, when appropriate. We also extracted data regarding the diary structure, when available. A thematic synthesis approach was used to analyze and synthesize qualitative data. DATA SYNTHESIS: Seventeen studies were analyzed. Most patients reported positive experiences with the ICU diary, such as understanding what they survived during critical illness, better understanding the process of recovery, gaining coherence of nightmares and delusional memories, realizing the importance of the presence of family and loved ones during ICU stay, and humanizing healthcare professionals that helped them survive critical illness. Patients also reported which components of the diary were important for their recovery, such as the presence of photographs and reading the diary with a healthcare professional, allowing the improvement of the concept of the ICU diary. CONCLUSION: This qualitative synthesis shows that patients recommend having an ICU diary, enlightening benefits such as better coping with the slow recovery from critical illness, strengthening family ties, and humanizing the ICU staff. It also identifies characteristics of the diary valued by the patients, in order to standardize the ICU diary according to their perspectives, and allowing future comparability between randomized controlled trials.

Capillary electroporation affects the expression of miRNA-122-5p from bull sperm cells.

Sperm-mediated gene transfer (SMGT) has a potential application in the generation of transgenic animals. Capillary electroporation consists of the application of electrical pulses, resulting in an increased transfection rate. Little is known about the impacts of the transfection of exogenous DNA on sperm epigenetics. MicroRNAs are epigenetic factors that are related to sperm motility. MiRNA-122-5p regulates genes that influence motility, and consequently, the fertilizing potential of sperm. Therefore, we aimed at identifying whether epigenetic factors such as microRNAs could be altered after DNA transfection, using the capillary electroporation technique. In this study, bull sperm was electroporated using voltages of 600 V, 1500 V, and 0 V (control group), with or without exogenous DNA. Parameters of sperm quality were analyzed using CASA and flow cytometry, and expression of the miRNA-122-5p was analyzed using RT-qPCR. It was observed that electroporation increased the internalization of exogenous DNA (P < 0.05), but did not impair the mitochondrial activity (P > 0.05). It reduced sperm motility (P < 0.05). The expression of miRNA-122-5p was upregulated in sperm electroporated at 1500 V, and the presence of exogenous DNA did not affect its expression. Thus, we can conclude that electroporation influences the expression of miRNA-122-5p from bull sperm cells.
