RESUMEN

Sífilis é uma infecção sexualmente transmissível (IST) que sinaliza a necessidade de efetivas políticas públicas devido ao aumento de casos na última década. Dessa forma, o objetivo do trabalho é descrever a incidência de sífilis no estado do Rio de Janeiro e no município de Seropédica. Métodos: foi realizado um estudo descritivo, com abordagem quantitativa. A coleta dos dados foi realizada por meio do Sistema de Informação de Agravos de Notificação (Sinan), referentes ao município de Seropédica e ao estado do Rio de Janeiro, no período de 2010 a 2022. Resultados: foram identificados 105.138, 79.609 e 42.819 casos de sífilis adquirida, em gestantes e congênita, respectivamente, no estado do Rio de Janeiro e 187, 140 e 79 casos de sífilis adquirida, em gestantes e congênita, respectivamente, no município de Seropédica. Foi observado uma incidência maior para sífilis adquirida entre homens em comparação com mulheres tanto no estado do Rio de Janeiro (62.719 versus 42.346) quanto no município de Seropédica (110 versus 77). Houve um aumento nas taxas de incidência de sífilis no estado do Rio de Janeiro e no município de Seropédica ao longo dos anos. Conclusão: a sífilis segue sendo uma doença com alta incidência no território do Rio de Janeiro. Nesse sentido, é importante elaborar estratégias em saúde pública mais efetivas às pessoas acometidas por tal infecção.


Syphilis is a sexually transmitted infection (STI) that signals the need for effective public policies due to the increase in cases in the last decade. Thus, the aim of this study is to describe the incidence of syphilis in the state of Rio de Janeiro and in the municipality of Seropédica. Methods: a descriptive study with a quantitative approach was carried out. Data collection was performed through the Sistema de Informação de Agravos de Notificação (Sinan), referring to the municipality of Seropédica and the state of Rio de Janeiro, from 2010 to 2022. Results: overall, 105.138, 79.609 and 42.819 cases of acquired syphilis, in pregnant women, and congenital syphilis, respectively, were identified in the state of Rio de Janeiro, and 187, 140, and 79 cases of acquired syphilis, in pregnant women, and congenital syphilis, respectively, were identified in the municipality of Seropédica. A higher incidence of acquired syphilis was observed among men compared to women both in the state of Rio de Janeiro (62.719 versus 42.346) and in the municipality of Seropédica (110 versus 77). There has been an increase in the incidence rates of syphilis in the state of Rio de Janeiro and the municipality of Seropédica over the years. Conclusion: syphilis continues to be a disease with a high incidence in the territory of Rio de Janeiro. In this sense, it is important to develop more effective public health strategies for people affected by this infection.

RESUMEN

OBJECTIVES: To evaluate the early and late results of surgical treatment of patients with bronchiectasis, comparing the Video-Assisted Thoracic Surgery (VATS) vs. the open thoracotomy (OT). METHODS: Observational retrospective study of patients who underwent surgery for bronchiectasis. Patients were divided into two groups according to surgical access OT/VATS. Variables collected included gender, age, preoperative symptoms, etiology, segments involved, FVC and FEV1, type of surgical resection, complications, mortality, and length of hospital stay. Late surgical results were classified as excellent, complete remission of symptoms; good, significative improvement; and poor, little/no improvement. RESULTS: 108 surgical resections (103 patients). OT group 54 patients (52.4%) vs. VATS 49 (47.6%). A high percentage of complications was observed, but no difference between the OT (29.6%) and VATS (24.5%) groups was found. Post-operative hospital stay was shorter in the VATS group (5.4 days) vs. the OT group (8.7 days (p=0.029). 75% of the patients had a late follow-up; the results were considered excellent in 71.4%, good in 26%, and poor in 2.6%. Regarding bronchiectasis distribution, an excellent percentage was obtained at 82.1% in patients with localized bronchiectasis and 47.5% with non-localized bronchiectasis, p=0.003. CONCLUSIONS: VATS leads to similar results regarding morbidity, compared to OT. However, VATS was related to shorter hospital stays, reflecting the early recovery. Late results were excellent in most patients, being better in patients with localized bronchiectasis. VATS should be considered a preferable approach for bronchiectasis lung resection whenever possible.

RESUMEN

SARS-CoV-2 caused the pandemic situation experienced since the beginning of 2020, and many countries faced the rapid spread and severe form of the disease. Mechanisms of interaction between the virus and the host were observed during acute phase, but few data are available when related to immunity dynamics in convalescents. We conducted a longitudinal study, with 51 healthy donors and 62 COVID-19 convalescent patients, which these had a 2-month follow-up after symptoms recovery. Venous blood sample was obtained from all participants to measure blood count, subpopulations of monocytes, lymphocytes, natural killer cells and dendritic cells. Serum was used to measure cytokines, chemokines, growth factors, anti-N IgG and anti-S IgG/IgM antibodies. Statistic was performed by Kruskal-Wallis test, and linear regression with days post symptoms and antibody titers. All analysis had confidence interval of 95%. Less than 35% of convalescents were anti-S IgM+, while more than 80% were IgG+ in D30. Anti-N IgG decreased along time, with loss of seroreactivity of 13%. Eosinophil count played a distinct role on both antibodies during all study, and the convalescence was orchestrated by higher neutrophil-to-lymphocyte ratio and IL-15, but initial stages were marked by increase in myeloid DCs, B1 lymphocytes, inflammatory and patrolling monocytes, G-CSF and IL-2. Later convalescence seemed to change to cytotoxicity mediated by T lymphocytes, plasmacytoid DCs, VEGF, IL-9 and CXCL10. Anti-S IgG antibodies showed the longest perseverance and may be a better option for diagnosis. The inflammatory pattern is yet present on initial stage of convalescence, but quickly shifts to a reparative dynamic. Meanwhile eosinophils seem to play a role on anti-N levels in convalescence, although may not be the major causative agent. We must highlight the importance of immunological markers on acute clinical outcomes, but their comprehension to potentialize adaptive system must be explored to improve immunizations and further preventive policies.

RESUMEN

The progression of chronic obstructive pulmonary disease (COPD) is characterized by functional changes in the airways. The lung-gut axis and gut microbiota (GM) have been linked to the pathophysiology of airway diseases. Regarding COPD, studies have shown that GM alterations could be related the stages of this disease. However, the relationship between GM and clinical, biochemical and immunological parameters in patients with COPD are not well understood. The aim of this study was to compare the relative abundance of specific groups of beneficial gut bacteria between COPD patients and healthy controls (CTLs) in order to evaluate relationships with metabolic and inflammatory markers in COPD. METHODS: We included 16 stable COPD patients and 16 healthy volunteer CTLs. The relative abundances of Bifidobacterium spp. (Bf) and Akkermansia muciniphila (Akk) bacteria and the Bacteroidetes and Firmicutes phyla were assessed by qPCR. Pulmonary function was evaluated by spirometry, biochemical parameters by colorimetric methods and plasma cytokine levels by cytometric bead array analysis. RESULTS: The Firmicutes/Bacteroides ratio was related to emergency hospital visits and six-minute walk test (6MWT) results. Furthermore, the relative abundance of Bf was associated with plasma concentrations of glucose, triglycerides, HDL-C and IL-10. In addition, Firmicutes levels and the Firmicutes/Bacteroidetes ratio were associated with the IL-12/IL-10 ratio, while Akk abundance was linked to IL-12 levels. CONCLUSIONS: The present findings suggest that the abundance of beneficial bacteria in the GM could influence clinical presentation and immunoregulation in COPD.

RESUMEN

ABSTRACT: Loturco, I, Pereira, LA, Mercer, VP, Oliveira, LP, Zanetti, V, Lima, L, Bastos, T, Moura, TBMA, and McGuigan, MR. Jump squat vs. resisted sprint training programs applied to elite youth soccer players: effects on sprint and power-related performance. J Strength Cond Res XX(X): 000-000, 2024-This study examined the effectiveness of 2 different and widely used training programs on the sprint and power-related performance of youth soccer players. Two distinct training strategies-vertically oriented jump squats (JSs) or horizontally oriented resisted sprints (RSs)-were executed under the same absolute loading conditions (i.e., 30% of the athletes' body mass [BM]) during a 4-week preseason period. Training schemes, loading intensities (based on %BM), and the number of experimental sessions were designed in conjunction with the soccer club's coaching staff, considering the calendar, available resources, and regular training programs. Twenty-five under-17 soccer players performed a series of speed, power, and jump tests before and after 10 resisted training sessions, consisting solely of loaded JS or RS. Overall, neither group (i.e., JS or RS training groups) exhibited any improvement in linear sprint and change-of-direction (COD) speed. Conversely, vertical jumping ability and peak velocity in the loaded JS increased significantly only in the JS group, which may positively affect players' performance and training prescription during short soccer preseasons. Given the challenges in enhancing sprint speed among soccer players during preseasons (and even over the competitive season), coupled with the limited effectiveness of RS in improving sprinting, COD, and jumping capabilities within congested and short training phases (i.e., ≤4 weeks), the regular use of RS training methods during these phases may be highly questionable. Coaches should carefully consider these critical limitations and potential disadvantages when designing neuromuscular training programs for soccer players during the preparatory phases of the annual training season.

RESUMEN

Stray dogs and cats pose significant challenges for public health and animal welfare due to their potential involvement in zoonotic disease transmission, accidents, and aggressions. Large urban centers exacerbated challenges due to the presence of these animals in public areas with high human density. Ethical Population Management Programs (EPMP), rooted in the One Health approach, are crucial for addressing this issue comprehensively. This study aimed to demonstrate the approach on cats and dogs EPMP and evaluate the perceptions of academic community regarding EPMP implementation on a campus situated in urban territory. The study was conducted at the Pampulha campus of UFMG in Belo Horizonte, Brazil. In response to issues of animal abandonment and conflicts, the Permanent Commission for Animal Policies (CPPA-UFMG) was established in 2019 to manage the campus's dog, cat, and wildlife populations. The commission implemented the Trap-Neuter-Return (TNR) method, along with health assessments and vaccinations for animals. Interviews were conducted with campus staff to gauge their perception of animal management strategies. Retrospective and prospective analyses of the commission's actions were carried out to assess implementation processes and challenges. The animal population survey conducted on campus between July 2018 and September 2021 revealed a total of 266 animals recorded. Among these animals, 195 were cats (73.3%) and 71 were dogs (26.7%), with the majority being adults. Subsequent surveys in 2019 and 2021 showed a slight increase in the animal population, with measures such as sterilization contributing to population control. Perception analysis among campus users indicated strategies such as TNR were widely endorsed for population control. The employees perception questionnaire was applied to 115 individuals, representing 42 units/departments and five gates. Associations were found between these beliefs and support for institutional actions. The majority favored sterilization (92.17%) and agreed that TNR is an appropriate approach to population control. Overall, the study reflects a community concerned about animal welfare and supportive of measures to address population management and cruelty prevention. The continuous efforts of the university's CPPA have led to stability in the resident animal population, indicating success in achieving population control objectives.

RESUMEN

BACKGROUND: To quantify fatty infiltration and degree of paraspinal muscle degeneration in patients submitted to tubular microdiscectomy and conventional open microdiscectomy. METHODS: A prospective cohort of patients was submitted to microdiscectomy for lumbar disc herniation after failure of conservative treatment. Selection of the technique was based on the surgeon's preference. Analysis of the multifidus muscle was performed using the Goutallier system and the percentage of fat in the muscle. Preoperative and 1-year postoperative T2-weighted magnetic resonance imaging was used, and statistical analysis was carried out using the Wilcoxon test and Spearman correlation test using a significance level of 5%. RESULTS: Thirty-two patients were included in the study. The percentage of fatty infiltration in the muscle increased on both sides of the spine 1 year after surgery, although only the ipsilateral side presented statistical significance in patients submitted to conventional microdiscectomy (43.3% preoperative and 57.8% postoperative). Muscular degeneration increased significantly ipsilateral to the disc herniation according to the Goutallier classification (grades 1-2) for both interventions. No statistically significant difference was found for fatty infiltration scores or for the degree of muscular degeneration of the multifidus in the comparative analysis of the methods. CONCLUSIONS: Muscular damage resulting from surgery of lumbar disc herniation significantly increases fatty infiltration and degeneration of the multifidus. Muscular degeneration was associated with worsening back pain. CLINICAL RELEVANCE: While no significant difference was found between the techniques, the tubular minimally invasive approach shows a tendency for less muscle damage. These findings highlight the importance of minimizing muscle injury during surgery to improve postoperative recovery and long-term outcomes.

RESUMEN

BACKGROUND: The literature is unclear about how the different attachment systems for overdentures impact the maximum bite force, the masticatory efficiency and how this impact in the oral health self-perception in patients. OBJECTIVE: To evaluate the effect of two attachment systems (O-ring and Locator) for mandibular overdenture using single implant on quality of life, maximum bite force (BF) and masticatory efficiency (ME). METHODS: Twenty-eight completely edentulous denture wearers with a mandibular symphysis implant were randomly selected and allocated into two groups in a crossover study, considering O-ring and Locator attachment types. The quality of life and self-perception of oral health were assessed using the Oral Health Impact Profile (OHIP-Edent) and Geriatric Index of Determination of Oral Health (GOHAI) questionnaires, respectively. BF was measured using a gnathodynamometer and ME by chewing silicone cubes and almonds in different numbers of cycles. RESULTS: There was no difference between the attachment systems about self-perceived oral health and impact on quality of life (p > .05). The O-ring-type system obtained a significantly higher BF than the locator-type system (p = .04). Regardless of the food chewed, no statistically significant difference was observed with the type of attachment (p > .05). The ME was directly proportional to the masticatory cycles only for almonds (p < .01). CONCLUSIONS: Locator and O-ring inserts had a similar impact on patients' quality of life, self-perception of oral health and ME. Additionally, the O-ring system exhibited superior properties in the BF.

RESUMEN

Home office (HO) stands out as one of the most promising and popular forms of teleworking, especially after the COVID-19 pandemic. Therefore, many companies want to implement or maintain this working method, given its numerous advantages. However, there are adverse effects that are mainly related to physical and mental health. This article presents ergonomic analyses of HOs in neighborhoods considered heat islands. Temperature levels, extreme low-frequency non-ionizing radiation (ELF-NIR), illuminance, physical layout characteristics, and physiological parameters of teleworkers were measured. The results reveal that 92% of these professionals work 6 to 8 h daily with an ambient temperature between 25 and 30 °C, illumination levels in the range 11.20-290 Lux, and ELF-NIR > 0.4 µT. The majority of teleworkers are overweight (BMI > 24.9), and some of them have blood pressure higher than average values (129 mmHg for systolic and 84 mmHg for diastolic) in addition to a reduction in the number of red blood cells and hematocrits. Symptoms such as burning sensation, dryness, tired eyes, redness, itching, and photophobia (light sensitivity) show a 68.95% similarity. These HOs do not meet the required ergonomic and health standards.

RESUMEN

INTRODUCTION: Chronic venous disease (CVD) is a highly prevalent disease that presents a wide spectrum of clinical expressions due to abnormalities in the venous system. Patients often have major functional changes that can limit daily activities. However, the functional factors associated with the severity of the disease remain poorly understood. OBJECTIVE: To identify the functional factors associated with CVD severity. METHODS: Seventy-five patients with CVD (92.0% females, 49.6 ± 13.3 years) were evaluated through clinical examination, lower limb perimetry, ankle range of motion (AROM), and lower limb muscle strength by the Heel Rise test, and Sit-to-stand test. Patients were stratified according to the disease severity as mild (telangiectasia, varicose veins, or edema in the lower limbs) or severe CVD (trophic changes or venous ulcer). RESULTS: Patients with severe CVD (n = 13) were older (p = 0.002), predominantly male (p = 0.007), with reduced AROM in dorsiflexion (p = 0.028) and inversion (p = 0.009), reduced lower limb strength by the Heel Rise test (p = 0.040), and greater circumference of the calf (p = 0.020), ankle (p = 0.003), and plantar arch (p = 0.041) when compared to mild CVD (n = 62). Advanced age, male sex, lower ankle range of motion in dorsiflexion, and greater ankle and plantar arch circumferences were associated with CVD severity. However, the ankle circumference (OR 1.258, 95% CI: 1.008-1.570; p = 0.042), together with advanced age and male sex, was the only functional variable that remained independently associated with CVD severity. CONCLUSION: The increased ankle circumference was a determinant of the CVD severity and may assist in risk stratification and guide treatment goals in this population.

RESUMEN

A pesquisa investigou o processo de criação e gestão do Parque dos Ferroviários, localizado na cidade de Araguari-MG, analisando tal objeto sob olhar interrelacional do lazer e turismo, paisagismo, arquitetura e urbanismo. Analisou-se as transformações vivenciadas pelo espaço, bem como o processo de projeto para a reabilitação como parque urbano contemporâneo em área histórica protegida, esclarecendo o transcurso de elaboração do projeto da paisagem e de planejamento da gestão visando a plena adequação do espaço ao uso público cotidiano e turístico. Assentou-se no pressuposto de que o olhar sobre o restauro arquitetônico e ao reuso das edificações, apenas, não promoverá uma adequada aproprição social do lugar, sendo necessário uma análise da contribuição crítica dos estudos de lazer para que o Parque dos Ferroviários aflore sua potencialidade de significados.


The research investigated the process of creation and management of Parque dos Ferroviários, located in the city of Araguari-MG (Brazil), analyzing this object from the interrelational perspective of leisure, tourism, landscape, architecture and urbanism. The transformations experienced by the space were analyzed, as well as he rehabilitation process as a historic contemporary urban park in a protected area, clarifying the development of the landscape project and management planning aimed at fully adaptingthe space to everyday public and tourist use. It was based on the assumption that looking at the architectural restoration and reuse of buildings alone will not promote an adequate social appropriation of the place, requiring an analysis of the critical contribution of leisure and tourism studies, so that the Parque dos Ferroviários emerges its potential for meanings.

RESUMEN

Aim: To evaluate the spatial distribution of MIH opacities in first permanent molars (FPM). Materials and methods: an analysis of intraoral photographs of FPM with demarcated MIH opacities was conducted. The presence of opacity was computed in a digital matrix, discriminating the anatomical regions of the FPM surfaces. The frequencies of distribution of the opacities were descriptively analyzed through 227 FPM digital images of 89 children built in GIMP and Python and by Spearman correlation (= 0,05). Results: the occlusal surface was the most affected one (94% to 100%). In the upper FPM, the palatine surface was the second most affected one (84%-91%). In the lower FPM, the vestibular surface was the second most affected one (85%-80%). A similar pattern of opacity distribution was observed in the contralateral teeth. On smooth surfaces, opacities were more frequent in the regions closer to the occlusal surface than to the cervical one. Conclusion: MIH opacities were mostly present on occlusal, vestibular, and lingual/palatine surfaces, respectively. There is a possibility that the occurrences are in accordance with the chronology of dental formation.

RESUMEN

Chagas cardiomyopathy (ChC) presents many biopsychosocial complexities, highlighting the need to have patient self-report questions. This study demonstrates the scope of the use of patient-reported outcome measures (PROMs) in patients with ChC and highlights the main research gaps. This is a scoping review and the search strategy was performed in the Online Medical Literature Analysis and Retrieval System (MEDLINE), Excerpta Medica database (EMBASE), Accumulated Index of Nursing and Allied Health Literature (CINAHL), Cochrane Central, Latin American Literature and Caribbean in Health Sciences (LILACS) and Diagnostic Test Accuracy (DITA). The search identified 4484 studies and 20 studies met the inclusion criteria. The Short-Form of 36 items (SF-36) had potential prognostic value and the ability to identify systolic dysfunction. The Human Activity Profile was able to screen for functional impairment, and the New York Heart Association showed potential prognostic value. The SF-36 and Minnesota Living with Heart Failure Questionnaire were responsive to interventions. The pharmaceutical care affected adherence to treatment as assessed by the Morisky score and also for SF-36. Despite the increased use of PROMs, there are still a large number of gaps in the literature, and further studies using PROMs are needed.

RESUMEN

The interaction of Plasmodium falciparum-infected red blood cells (iRBCs) with the vascular endothelium plays a crucial role in malaria pathology and disease. KAHRP is an exported P. falciparum protein involved in iRBC remodelling, which is essential for the formation of protrusions or "knobs" on the iRBC surface. These knobs and the proteins that are concentrated within them allow the parasites to escape the immune response and host spleen clearance by mediating cytoadherence of the iRBC to the endothelial wall, but this also slows down blood circulation, leading in some cases to severe cerebral and placental complications. In this work, we have applied genetic and biochemical tools to identify proteins that interact with P. falciparum KAHRP using enhanced ascorbate peroxidase 2 (APEX2) proximity-dependent biotinylation and label-free shotgun proteomics. A total of 30 potential KAHRP-interacting candidates were identified, based on the assigned fragmented biotinylated ions. Several identified proteins have been previously reported to be part of the Maurer's clefts and knobs, where KAHRP resides. This study may contribute to a broader understanding of P. falciparum protein trafficking and knob architecture and shows for the first time the feasibility of using APEX2-proximity labelling in iRBCs.

RESUMEN

O tratamento endodôntico de dentes com rizogênese incompleta requer uma atenção especial, uma vez que o tratamento convencional é inviável e devemos evitar a perda dos dentes permanentes. Na maioria das vezes, as causas que interrompem a formação radicular são os traumatismos dentários e as cáries extensas, que podem atingir a polpa coronária, podendo levar, inclusive, à necrose pulpar. Atualmente, esses casos têm sido tratados por meio da apicificação, apicogênese e da revascularização pulpar, com uso de medicações a base de hidróxido de cálcio, antibiótico e MTA (Agregado trióxido mineral). Nessas técnicas, a intenção é induzir o desenvolvimento radicular completo ou o fechamento apical por tecido duro calcificado. O objetivo deste trabalho foi realizar uma breve revisão de literatura, utilizando artigos científicos disponíveis nas plataformas Café (UFF), Scielo e PubMed, a fim de descrevermos os conceitos de apicificação, apicogênese e revascularização, expondo as suas indicações e condutas clínicas ideais para a realização destes tratamentos. Pode-se concluir que são procedimentos clínicos simples e de conhecimento extremamente importantes para qualquer cirurgião-dentista, uma vez que são tratamentos emergenciais bastante comuns no dia a dia. Além disso, sabe-se da necessidade de manter um dente permanente sadio na boca, que pode evitar grandes problemas no futuro.


Endodontic treatment on teeths with incomplete rhizogenesis requires special attention, since conventional treatment is infeasible and we must avoid the loss of permanent teeth. Most often, the causes that interrupt root formation are dental trauma and extensive caries, which can reach the coronary pulp and may even lead to pulpal necrosis. Currently, these cases have been treated through apexification, apexogenesis and pulpal revascularization, with the use of calcium hydroxide, antibiotic and MTA (Aggregate mineral trioxide) base medications. In these techniques, the intent is to induce complete root development or apical closure by calcified hard tissue. The objective of this work was to carry out a review of literature, using scientific articles available on the Café platform (UFF), Scielo and PubMed, in order to describe the concepts of apexification, apexogenesis and revascularization, exposing their indications and ideal clinical procedures for the realization of these treatments. It can be concluded that they are simple clinical procedures and of knowledge extremely important for any dentist, since they are emergency treatments that are quite common day by day. In addition, it is known that one needs to maintain a permanent healthy tooth in the mouth, which can avoid major problems in the future.

RESUMEN

In recent years, there has been an increase in the delivery and evaluation of parent education programs within youth sport. Subsequently, some recent reviews of these programs have been conducted. However, one consistent issue across many of the programs and associated review papers is the lack of an appropriate evaluation framework to guide the planning or associated reporting of the outcomes of the interventions. This has limited understanding of the overall impact of sport parenting interventions. Thus, the purposes of the current study were as follows: (a) to identify commonalities in the reporting and evaluation of parent education programs; (b) to identify gaps in the reporting and evaluation of parent education programs; (c) to draw these insights together to provide suggestions regarding how the RE-AIM could be used to enhance planning and evaluation of evidence-based programs for parent education in sport. Specifically, utilizing the RE-AIM framework to provide insights into pertinent evaluation metrics, this integrative review aimed to identify commonalities and gaps in the reporting of parent education programs. The RE-AIM framework considers the essential elements to assess the external and internal validity of interventions through five dimensions: Reach, Effectiveness, Adoption, Implementation, and Maintenance (Am J Public Health. 1999;89(9):1322-1327). Subsequently, the review aimed to provide suggestions regarding strategies to enhance the planning and evaluation of evidence-based programs for parent education in sport. Overall, the analysis demonstrated that most studies presented some pertinent evaluation information related to the RE-AIM framework, such as the number of participants and contacts made, the measures used, and the program level. However, the studies also lacked information on participant exclusion criteria, the method used to select the delivery agent (e.g., parents engaged in the program), and cost measures. Overall, the current study identified various areas where programs could be enhanced, specifically related to reporting procedural elements (e.g., program design, target population, and costs) pertaining to the implementation of parent education programs.

RESUMEN

(1) Background: Performance after Cochlear Implantation (CI) can vary depending on numerous factors. This study aims to investigate how meningitis or otosclerosis can influence CI performance. (2) Methods: Retrospective analysis of CI performance in patients with etiological diagnosis of meningitis or otosclerosis, comparing the etiologies and analyzing the image findings, along with electrode array insertion status and technique. (3) Results: Speech recognition in CI patients with otosclerosis improves faster than in patients with meningitis. Other features such as radiological findings, degree of cochlear ossification, surgical technique used and total or partial insertion of electrodes do not seem to be directly related to speech recognition test performance. (4) Conclusions: Patients should be warned that their postoperative results have a strong correlation with the disease that caused their hearing loss and that, in cases of meningitis, a longer duration of speech-language training may be necessary to reach satisfactory results.

RESUMEN

The western flower thrips, Frankliniella occidentalis, poses a significant challenge in global agriculture as a notorious pest and a vector of economically significant orthotospoviruses. However, the limited availability of genetic tools for F. occidentalis hampers the advancement of functional genomics and the development of innovative pest control strategies. In this study, we present a robust methodology for generating heritable mutations in F. occidentalis using the CRISPR/Cas9 genome editing system. Two eye-colour genes, white (Fo-w) and cinnabar (Fo-cn), frequently used to assess Cas9 function in insects were identified in the F. occidentalis genome and targeted for knockout through embryonic microinjection of Cas9 complexed with Fo-w or Fo-cn specific guide RNAs. Homozygous Fo-w and Fo-cn knockout lines were established by crossing mutant females and males. The Fo-w knockout line revealed an age-dependent modification of eye-colour phenotype. Specifically, while young larvae exhibit orange-coloured eyes, the colour transitions to bright red as they age. Unexpectedly, loss of Fo-w function also altered body colour, with Fo-w mutants having a lighter coloured body than wild type, suggesting a dual role for Fo-w in thrips. In contrast, individuals from the Fo-cn knockout line consistently displayed bright red eyes throughout all life stages. Molecular analyses validated precise editing of both target genes. This study offers a powerful tool to investigate thrips gene function and paves the way for the development of genetic technologies for population suppression and/or population replacement as a means of mitigating virus transmission by this vector.

RESUMEN

The complete safety and efficacy of endoscopic cyclophotocoagulation (ECP) remain unclear in the literature and, to our knowledge, there are no current meta-analyses on phaco-ECP versus phacoemulsification alone to date. Thus, we conducted a systematic review and meta-analysis comparing these two strategies through studies, assessing the effectiveness and safety of outcomes in a population with glaucoma. The protocol for this systematic review was registered in the PROSPERO International Prospective Register of Systematic Reviews (CRD42023482376). We systematically searched PubMed, Embase, and Web of Science from inception to December 2023. A random-effects model was used for all analyses due to heterogeneity. Review Manager 5.3 (Cochrane Centre, The Cochrane Collaboration, Denmark) was used for statistical analysis. Finally, nine studies were included in this comprehensive review and a total of 5389 eyes were analyzed in our study. In comparison to the ECP and phacoemulsification group, those receiving phacoemulsification alone showed better results in best-corrected visual acuity (MD 0.09; CI 95% 0.03 to 0.16; I²=0%), but worse outcomes in intraocular pressure (IOP) (MD -1.49; 95% CI -2.29 to -0.68; I²=29%) and use medications (MD -0.75; 95% CI -0.94 to -0.56; I²=0%) in the last visit. Complication rates, both general and serious, were significantly different between the groups, indicating the potential impact of combined procedures on patient outcomes. Thus, combining ECP with phacoemulsification for glaucoma treatment showed sustained IOP reduction and decreased medication dependence. However, higher complication rates suggest careful consideration of risks. More extensive research with larger trials and longer follow-ups is needed to validate findings and address limitations, providing valuable insights into this treatment approach.

RESUMEN

Fish is an important source of food and income for a significant portion of the Amazonian population, especially those who live along the rivers and lakes in the region. Pseudoplatystoma punctifer (Castelnau, 1855), known as surubim, is a species of Neotropical catfish widely exploited by fisheries and commercially valuable in the Guaporé River basin, Brazil. However, population dynamics are poorly known in the region. To understand the population structure and reproductive biology aspects of the surubim, monthly experimental fisheries were carried out in the São Miguel River, state of Rondônia, Brazil, between August 2020 and July 2021. The captured fish were weighed, and its gonads were removed and weighed for histological analyses (microscopic description) and classification of the maturation stages (macroscopic description). The collected gonads were fixed in 10% buffered formalin, dehydrated, cut into 4-µm-thick sections, and stained with hematoxylin and eosin. A total of 34 individuals were collected (20 females and 14 males), showing positive allometric growth and condition factor from 0.81 to 1.79 for females and males, respectively. Females were larger in size and weight than males. P. punctifer reaches its first maturation at an average length of 68.30 cm, indicating the importance of respecting the minimum capture size as an alternative to ensure the natural stocks of this fishery resource in the region. The results provide support for the establishment of public policies and actions for conservation, management, and regulation of fishing.
