ABSTRACT
Abstract Objective To evaluate the risk factors and outcomes in patients surgically treated for subaxial cervical spine injuries with respect of the timing of surgery and preoperative physiological parameters of the patient. Methods 26 patients with sub-axial cervical spine fractures and dislocations were enrolled. Demographic data of patients, appropriate radiological investigation, and physiological parameters like respiratory rate, blood pressure, heart rate, PaO2 and ASIA impairment scale were documented. They were divided pre-operatively into 2 groups. Group U with patients having abnormal physiological parameters and Group S including patients having physiological parameters within normal range. They were further subdivided into early and late groups according to the timing of surgery as Uearly, Ulate, Searly and Slate. All the patients were called for follow-up at 1, 6 and 12 months. Results 56 percent of patients in Group S had neurological improvement by one ASIA grade and a good outcome irrespective of the timing of surgery. Patients in Group U having unstable physiological parameters and undergoing early surgical intervention had poor outcomes. Conclusion This study concludes that early surgical intervention in physiologically unstable patients had a strong association as a risk factor in the final outcome of the patients in terms of mortality and morbidity. Also, no positive association of improvement in physiologically stable patients with respect to the timing of surgery could be established.
Resumo Objetivo Avaliar os fatores de risco e os desfechos em indivíduos submetidos ao tratamento cirúrgico de lesões subaxiais da coluna cervical em relação ao momento da cirurgia e aos parâmetros fisiológicos pré-operatórios dos pacientes. Métodos O estudo incluiu 26 pacientes com fraturas e luxações subaxiais da coluna cervical. Dados demográficos, investigação radiológica apropriada e parâmetros fisiológicos, como frequência respiratória, pressão arterial, frequência cardíaca, pressão parcial de oxigênio (PaO2) e escalas de disfunção da American Spine Injury Association (ASIA), foram documentados. No período pré-operatório, os pacientes foram divididos em dois grupos. O grupo instável (I) continha pacientes com parâmetros fisiológicos anormais e o grupo estável (E) era composto por pacientes com parâmetros fisiológicos dentro da faixa de normalidade. Os pacientes foram ainda subdivididos em grupos de tratamento precoce e tardio de acordo com o momento da cirurgia como Iprecoce, Itardio, Eprecoce e Etardio. Todos os pacientes foram chamados para consultas de acompanhamento em 1, 6 e 12 meses. Resultados Cinquenta e seis por cento dos pacientes do grupo E apresentaram melhora neurológica em um grau ASIA e desfecho bom independentemente do momento da cirurgia. Os desfechos em pacientes do grupo I com parâmetros fisiológicos instáveis e submetidos à intervenção cirúrgica precoce foram maus. Conclusão Este estudo conclui que a intervenção cirúrgica precoce em pacientes com instabilidade fisiológica teve forte associação como fator de risco no desfecho final em termos de mortalidade e morbidade. Além disso, não foi possível estabelecer nenhuma associação positiva de melhora em pacientes com estabilidade fisiológica em relação ao momento da cirurgia.

Background: Countries around the world are now racing to vaccinate people against SARS-CoV-2, the virus that causes COVID-19. The Government of India also rolled out its vaccination drive from 16th January ‘2021. Aims: To estimate the antibody response of the COVID-19 vaccine in the form of SARS-COV-2 IgG antibodies in vaccinated healthcare workers. Methods: Prospective follow-up was study conducted on healthcare workers (HCWs) of a Medical college in Dehradun, Uttarakhand. Healthcare workers who have been vaccinated for COVID-19 were tested for SARS-CoV-2-IgG antibodies at regular intervals i.e at 4 weeks after the 1st dose and then again at 4 weeks after the 2nd dose. The third sample was taken 6 months after the 2nd dose. Results: A total of 302 HCWs were enrolled in the study who gave their samples for IgG antibody estimation after the Covishield vaccine. After 4 weeks of completion of both doses, 96% HCWs formed SARS-COV-2 IgG antibodies, whereas 4% didn’t. Then after 6 months of follow-up, 14% HCWs have become negative for antibodies and better immunity is seen in people who also got infected with COVID-19 during this time. Conclusion: This study concludes that the immunity gained after vaccination is waning off in around 6 months and there is a need for a booster dose, especially for people at high risk. The infection control practices still play a crucial role in the prevention of this deadly disease.
ABSTRACT
ABSTRACT Objectives: We aimed to assess the risk of injury associated with training activities of Korean elite female fencing athletes by weapon category. Methods: We prospectively collected 2021 data on 80 elite female fencing athletes at the Korean Training Center. Injury incidence rates were expressed as Poisson rates with a 95% confidence interval. We used χ2 tests to compare injury locations and recovery times by weapon category. Results: A total of 233 injuries were recorded, averaging 3.27 (95% CI, 2.86-3.72) injuries per 1,000 training hours. The sabre had the highest injury incidence rate, followed by the epee and the foil. Injuries to fencing athletes were the most common in the lower extremities (46.35%), followed by the upper extremities (24.03%), trunk (20.17%), and head and neck area (9.44%). The weapon category did not affect the body regions (p=0.425). However, recovery time differed significantly by body region (p=0.021). Conclusions: The weapon category was found to affect the injury incidence rate. In addition, recovery time varied depending on body region. Further research is needed to clarify these results. Level of evidence II; Therapeutic studies - investigation of treatment results.

ABSTRACT
Objective:Development and validation of a nomogram for predicting the 4-year incidence of type-2 diabetes mellitus (T2DM) in a Chinese population was attempted.Methods:This prospective cohort study was conducted in Shijingshan District Pingguoyuan Community (Beijing, China) from December 2011 to April 2012 among adults aged≥40 years not suffering from T2DM. Finally, 8 058 adults free of T2DM were included with a median duration of follow-up of 4 years. Participants were divided into a modeling group and verification group using simple random sampling at a ratio of 7∶3. Univariate and multivariate Cox proportional risk models were applied to identify the independent risk predictors in the modeling group. A nomogram was constructed to predict the 4-year incidence of T2DM based on the results of multivariate analysis. The Concordance Index and calibration plots were used to evaluate the differentiation and calibration of the nomogram in both groups.Results:A total of 5 641 individuals were in the modeling group and 2 417 people were in the validation group, of which 265 and 106 had T2DM, respectively, at 4-year follow-up. In the modeling group, age ( HR=1.349, 95% CI 1.011-1.800), body mass index ( HR=1.347, 95% CI 1.038-1.746), hyperlipidemia ( HR=1.504, 95% CI 1.133-1.996), fasting blood glucose ( HR=4.189, 95% CI 3.010-5.830), 2-h blood glucose level according to the oral glucose tolerance test ( HR=3.005, 95% CI 2.129-4.241), level of glycosylated hemoglobin ( HR=3.162, 95% CI 2.283-4.380), and level of γ-glutamyl transferase ( HR=1.920, 95% CI 1.385-2.661) were independent risk factors for T2DM. Validation of the nomogram revealed the Concordance Index of the modeling group and validation group to be 0.906 (95% CI 0.888-0.925) and 0.844 (95% CI 0.796-0.892), respectively. Calibration plots showed good calibration in both groups. Conclusion:These data suggest that our nomogram could be a simple and reliable tool for predicting the 4-year risk of developing T2DM in a high-risk Chinese population.
ABSTRACT
Objective:To evaluate the efficacy of implant surface culture in identification of pathogens for fracture device-related infection.Methods:A prospective study was conducted to include the eligible patients who were diagnosed with infection after fracture fixation and needed surgical removal of the implants according to treatment principles at Division of Orthopaedics and Traumatology, Department of Orthopaedics and Traumatology, Nanfang Hospital from November 2020 to January 2023. With informed consent, after rinsing with aseptic normal saline twice, their implants were gently covered with a thin layer of tryptone soy agar medium. Thereafter, the implants were incubated at 37 ℃ with 5% CO 2. Changes on the surface and in the surroundings of the implants were observed every day for consecutive 2 weeks to avoid drying up by supplementing the medium when necessary. Once pathogen colonies formed, samples were collected at 3 independent sites using sterile swabs for laboratory identification. Comparisons were made between the samples from implant surface culture and the intraoperative multisite samples from conventional culture. Results:Included were a total of 75 patients [56 males and 19 females with an age of (46.2±15.4) years]. The most common infection site was the tibia (37 cases), and the most common type of implants was plate and screw (59 cases). The positive rate of implant surface culture was significantly higher than that of conventional culture (86.7% vs. 52.0%, P<0.001). 80.5% (29/36) of the negative patients detected by the conventional culture obtained positive results by the implant surface culture; three of the positive patients detected by the conventional culture obtained negative results by the implant surface culture. The culture results were positive by both culture methods in 36 patients, and consistent by both culture methods in 35 patients, yielding a consistent rate of 97.2% (35/36). The time for implant surface culture was significantly shorter than that for conventional culture [1 (1, 2) d versus 3 (3, 4) d] ( P<0.001). Of the 65 positive patients by the implant surface culture, 59 were detected with monomicrobial infection, with Staphylococcus aureus on the top (29 cases). Conclusion:As the implant surface culture, a novel method, may be superior to the conventional culture in a significantly higher positive rate and a shorter culture time, it may be used as an effective adjunct to the conventional culture in identification of pathogens for fracture device-related infection.
ABSTRACT
Fundamento: el incremento de la responsabilidad personal con la salud en la población cubana es un resultado esperado del Plan de Desarrollo Socialista hasta el año 2030. Para lograr esta meta se necesita un ejercicio de planificación estratégica cuya primera etapa es el análisis estructural del problema. Objetivo: identificar las variables relacionadas con los niveles de responsabilidad personal con la salud en la población cubana, describir las relaciones entre ellas y determinar las que resultan estratégicas para fomentar el cambio. Métodos: se realizó un estudio de prospectiva estratégica para el análisis estructural de los niveles de responsabilidad personal con la salud en Cuba. Mediante muestreo no probabilístico de casos críticos se contactó con 24 expertos que elaboraron una lista de variables relacionadas con el problema de estudio y las relaciones entre ellas. Se utilizó el programa Matriz de impactos cruzados- multiplicación aplicada a una clasificación, para el análisis de los datos. Resultados: se identificaron 19 variables, de las cuales cinco son variables determinantes, seis variables estratégicas (acción intersectorial, normas sociales y marco jurídico, enfoque paternalista en salud, rendición de cuentas individual y del Estado-Gobierno, alfabetización en salud y apoyo al cuidado y bienestar), dos variables objetivo y tres variables resultados y autónomas respectivamente. Conclusiones: el incremento de los niveles de responsabilidad personal con la salud dependerá de la acción intersectorial, la actualización del marco jurídico y formas innovadoras para la rendición de cuenta de todos los actores sociales. Será necesario, además, alcanzar mejoras en la alfabetización en salud, mayor acompañamiento a los esfuerzos de los individuos para el autocuidado y el abandono de prácticas paternalistas que expropien a los ciudadanos de sus responsabilidades.
Background: the increase in personal responsibility for health in the Cuban population is an expected result of the Socialist Development Plan until the year 2030. To achieve this goal, a strategic planning exercise is needed. The structural analysis of the problem is the first stage of this exercise. Objective: to identify the variables related to the current and future levels of personal responsibility for health in the Cuban population, to describe the relationships between them and to determine those that, due to their levels of dependency and influence in the system, are strategic for promoting change. Methods: a strategic prospective study was carried out for the structural analysis of the levels of personal responsibility for health in Cuba. Through non-probabilistic sampling of critical cases, 24 experts were contacted who drew up a list of related variables to the study problem, assigned them and described the relationships between them. The cross-impact matrix-multiplication program applied to a classification was used for data analysis. Results: 19 variables were identified, of which five are determining variables, six challenge variables, two target variables and three result and autonomous variables, respectively. Intersectoral action, social norms and legal framework, paternalistic approach to health, individual and State-Government accountability, health literacy and support for care and well-being were considered strategic. Conclusions: the increase in the levels of personal responsibility for health will depend on intersectoral action, the updating of the legal framework and innovative forms for the accountability of all social actors. It will also be necessary to achieve improvements in health literacy, greater accompaniment to the efforts of individuals for self-care and the abandonment of paternalistic practices that expropriate citizens from their responsibilities.
ABSTRACT
ABSTRACT Introduction: Open fractures, although uncommon, with trauma have costs that exceed all other reasons for hospitalizations. Its epidemiology has fundamental importance to plan treatment and define priorities. Objective: To assess prospectively the epidemiological profile of open fractures and the degree of satisfaction with initial care. Methods: Epidemiological, prospective, descriptive, observational study was carried out in a convenience sample of open fractures. Quantitative, qualitative, and epidemiological aspects regarding open fractures were evaluated, as well as the degree of satisfaction with the initial care. Results: 124 patients treated with 155 open fractures. 88% were male; mean age 43 years (± 42.99); non-white (56.72%); married (52.41%); low level of education (51.60%); farmer, self-employed, bricklayer, industrialist (51.60%); with monthly earnings of up to 2 minimum wages (87%); healthy (76.13%); victims of labor accidents (39.51%) in bones of the hands (58.02%); 55% on the left side; attended between Thursday to Saturday (50%); work shift 6 a.m.-6 p.m. (77%). There was high level of satisfaction with the initial care provided (98%). Conclusion: Open fractures were related to healthy men, 43 years old, low education and low income, predominant in upper limbs, at 6 a.m. to 6 p.m., from Thursday to Saturday. Most were satisfied with the service provided. Level of Evidence II, Epidemiological, prospective, descriptive, observational study.

ABSTRACT
Abstract: In this study, we evaluated the knowledge, attitudes, and psychosocial impacts among Brazilian pediatric dentists during the COVID-19 pandemic. A cross-sectional study with primary data collection was carried out using an online structured questionnaire. Data were submitted to descriptive analysis by using absolute and relative frequencies. A chi-square test was used for association analysis and log-linear regression models to estimate the prevalence ratio (5%). The population comprised mostly women and knowledge regarding COVID-19 was satisfactory (above 80% in most items). N95 masks and faceshields were used, albeit 64.22% reported difficulty in providing dental care to children due to the need for extra Personal Protective Equipment. Thirty eight percent provided urgency/emergency dental care, 59.78% performed invasive procedures, 59.56% used high speed handpieces, 8.44% started using cariostatics, and 6.22% introduced the use of chemomechanical caries removal agents. Fear for the future (PR = 1.21) and use of medications (for anxiety, depression, or insomnia) increased (PR = 1.16) among the ones who had wage losses. Brazilian pediatric dentists have knowledge about COVID-19, and attitudes in their clinical routines changed due the pandemic. Financial life was harmed and a negative impact of the pandemic in psychosocial aspects of workers was found.
ABSTRACT
BACKGROUND@#A protective role for physical activity against the development of atrial fibrillation (AF) has been suggested. Stair climbing is a readily available form of physical activity that many people practice. Herein, we investigated the association between stair climbing and the risk of AF in a Japanese population.@*METHODS@#In this prospective cohort study, we used data of 6,575 people registered in the Suita Study, aged 30-84 years, and had no history of AF. The frequency of stair climbing was assessed by a baseline questionnaire, while AF was diagnosed during the follow-up using a 12-lead ECG, health records, check-ups, and death certificates. We used the Cox regression to calculate the hazard ratios and 95% confidence intervals of AF incidence for climbing stairs in 20-39%, 40-59%, and ≥60% compared with <20% of the time.@*RESULTS@#Within 91,389 person-years of follow-up, 295 participants developed AF. The incidence of AF was distributed across the stair climbing groups <20%, 20-39%, 40-59%, and ≥60% as follows: 3.57, 3.27, 3.46, and 2.63/1,000 person-years, respectively. Stair climbing ≥60% of the time was associated with a reduced risk of AF after adjustment for age and sex 0.69 (0.49, 0.96). Further adjustment for lifestyle and medical history did not affect the results 0.69 (0.49, 0.98).@*CONCLUSION@#Frequent stair climbing could protect from AF. From a preventive point of view, stair climbing could be a simple way to reduce AF risk at the population level.

Objective:To investigate the influence of hemoglobin glycation index (HGI) on the risk of incident chronic kidney disease (CDK) among nondiabetic patients.Methods:Prospective cohort study. At baseline, a total of 7 407 nondiabetic patients without a history of CKD from Pingguoyuan Community of the Shijingshan District in Beijing were included from December 2011 to August 2012, who were then divided into three groups according to the tertiles of their baseline HGI levels. The CKD incidence rate was compared among the different HGI groups at last follow-up. Cox multivariable regression was applied to evaluate whether HGI measures predicted CKD risk. Test for trend across tertiles were examined using ordinal values in separate models.Results:The mean age of the subjects was (56.4±7.5) years, and 4 933 (66.6%) were female. At mean follow-up of 3.23 years, 107 (1.4%) individuals developed CKD. The incidence of CKD was gradually increasing from the low to high HGI groups [1.1% (28/2 473) vs. 1.2% (31/2 564) vs. 2.0% (48/2 370), P=0.016]. In the multivariate Cox regression analysis, after adjustment for potential confounders, the high HGI group had a 68.5% increased risk of CKD compared with the low HGI group ( HR=1.685, 95% CI 1.023 to 2.774). CKD risk increased with increasing HGI tertiles ( P for trend=0.028). Conclusion:High HGI is associated with an increased risk for CKD in the nondiabetic population, indicating that HGI may help identify individuals at high risk for CKD.
ABSTRACT
During the COVID-19 pandemic, many manifestations of the disease appear in the oral, perioral and maxillofacial regions, either related to the virus itself or to the drugs used in the treatment. Aim: This study aims to identify the most common oral and perioral lesions in hospitalized patients with COVID-19 in the city of Mosul and their management; and also to evaluate the incidence and prevalence of these lesions. Material and Methods: Prospective study included 338 patients (138 females, 200 males) who had positive PCR results for SARS-CoV-2, with oral manifestations. All data were analyzed taking the means, frequencies, and percentage. Results: The most common lesions were colored lesions (31%) and stomatalgia (27%). The most common oral disorder and prior comorbidity combination was stomatalgia in patients with a history of hypertension. The most common associated systemic diseases were diabetes mellitus (19%) followed by hypertension (17%). Macular lesions had a higher response to drugs (40%) followed by stomatalgia (28%), in comparison with necrotic lesions (0%). Treatment of oral lesions included surgical interventions (26%) as well as conventional medical treatment (74 %). Conclusion: Oral and perioral disorders during COVID-19 are transitory and more evidence is warranted to efficiently address these comorbidities in the short term.

ABSTRACT Bipolar disorder (BD) has a large hereditary component. It is a disorder that begins in early adulthood, but about which it has been described a premorbid period preceding the onset of BD. During this herald expression psychiatric disorders and symptoms, such as depressive, manic, psychotic, anxious and others, may appear. Objective: To determine the psychopathological profile of a Bipolar Offspring (BO) group compared with the Community Control Offspring (CCO) group, and its evolution over time, including subthreshold symptoms and mental disorders. Methods: We conducted an observational mixed cohort study, with a prospective design. We included subjects from six to 30 years of age, from the region of Antioquia, Colombia. A total of 131 subjects from the risk group BO and 150 subjects from the CCO group were evaluated through validated psychiatric diagnostic interviews (K-SADS-PL and DIGS) at baseline and at 4 years follow up. All interviews were carried out by a staff blind to parent diagnoses. Follow-up assessment were complete in 72% of the offspring. Forty-two subjects were excluded as they surpassed the age of 30 years, and only 46 subjects were not followed (change of address or did not consent to participate). Results: Compared with the CCO group, the BO group had a higher frequency of affective disorder, psychotic disorder, externalizing disorders and use of the psychoactive substances during both assessments at time 1 and 2. The magnitude of the differences between the groups increased when they reach time 2. The BO group had a greater risk for presenting subthreshold symptoms and definitive psychiatric disorders, such as affective disorders, psychotic disorders and externalizing disorders. In addition, the BO group had a younger age of onset for psychoactive substances consumption. Conclusion: During the follow-up period, the BO group had a higher risk of presenting mental disorders compared with the CCO group. The most relevant symptoms and disorders that could precede the onset of BD were depressive, bipolar not otherwise specified, psychotic and substance use.
RESUMEN El trastorno bipolar (TB) tiene un gran componente hereditario. Es un trastorno que comienza en la edad adulta temprana, pero acerca del cual se ha descrito un período premórbido que precede al inicio de TB. Durante esta expresión heraldo, pueden aparecer trastornos y síntomas psiquiátricos, como depresivos, maníacos, psicóticos, ansiosos y otros. Objetivo: Determinar el perfil psicopatológico de un grupo de hijos de padres con TB (BO) en comparación con el grupo de hijos de padres control de la misma comunidad (CCO), y su evolución en el tiempo. Los síntomas subumbrales y los trastornos mentales serán incluidos. Métodos: Nosotros llevamos a cabo un estudio observacional mixto de cohorte, con diseño prospectivo. Incluimos sujetos de seis a 30 anos de edad, de la región de Antioquia, Colombia. Un total de 131 sujetos del grupo de riesgo BO y 150 sujetos del grupo CCO fueron evaluados a través de entrevistas de diagnóstico psiquiátricas validadas (K-SADS-PL y DIGS), al inicio yalos4anos de seguimiento. Todas las entrevistas se llevaron a cabo por personal ciego a los diagnósticos de los padres. La evaluación de seguimiento se completó en el 72% de la descendencia. Cuarenta y dos sujetos fueron excluidos ya que superaron la edad de 30 anos, y solo 46 sujetos no fueron seguidos (cambio de dirección o no dieron su consentimiento para participar). Resultados: En comparación con el grupo CCO, el grupo BO tuvo una mayor frecuencia de trastorno afectivo, el trastorno psicótico, los trastornos de externalización y el uso de las sustancias psicoactivas durante ambas evaluaciones en los tiempos 1 y 2. La magnitud de las diferencias entre los grupos aumentó cuando alcanzaron el tiempo 2. El grupo BO tuvo un mayor riesgo de presentar síntomas subumbrales y trastornos psiquiátricos definitivos, tales como trastornos afectivos, trastornos psicóticos y trastornos de externalización. Además, el grupo BO tuvo una edad de comienzo más baja para el consumo de sustancias psicoactivas. Conclusión: Durante el período de seguimiento, el grupo BO tuvo un mayor riesgo de presentar trastornos mentales en comparación con el grupo CCO. Los síntomas y trastornos más importantes que preceden al inicio del TB fueron: depresivo, bipolar no especificado de otra manera, psicóticos y el uso de sustancias.
ABSTRACT
ABSTRACT BACKGROUND: Colonoscopy is the gold standard for the diagnosis and treatment of adenomas. It is related with decreased colorectal cancer incidence and mortality. However, an important problem is missed colorectal adenoma. All efforts should be undertaken to reduce this rate. Enhancing imaging technologies including electronic chromoendoscopy and magnification has been increasingly adopted for improving the colorectal neoplasia detection rate and the detailed study of its surface, as well. I-scan images (Pentax, Tokyo, Japan) provides virtual chromoendoscopy in real-time during the examination to view the surface pattern, highlighting the microvasculature of the neoplastic lesion. The evidence on the impact of the use of I-scan on the colorectal adenoma detection rate is scarce. OBJECTIVE: To evaluate whether the use of I-scan has impact on the adenoma miss rate (AMR) of screening colonoscopy exams. METHODS: Observational and prospective study conducted by monitoring patients over 50 years undergoing colonoscopy. There were two groups: Group 1 - first inspection with standard high-definition white-light (HDWL) followed by a second inspection with I-scan 1; Group 2 - first inspection with I-scan 1 followed by a second inspection with standard HDWL. The primary outcome was the AMR from the first exam, calculated with the number of adenomas detected in the second exam, divided by the total number of adenomas detected in both exams. RESULTS: A total of 85 patients participated in the study. 14 were excluded, with a final sample of 71 patients, in the Group 1, 34 patients, and the Group 2, 37. A total of 58 adenomas were detected, 40 in the first inspection (20 in each group) and 18 in the second inspection in group 1. The overall AMR was higher for the Group 1 than the Group 2 (47.4% vs 0% P=0.0002). CONCLUSION: The use of I-scan 1 during colonoscopy exam reduces the AMR.
RESUMO CONTEXTO: O câncer colorretal é uma das principais causas de morte relacionada ao câncer em todo o mundo. A colonoscopia é o padrão ouro para diagnosticar e tratar lesões precoces, levando à diminuição da incidência e mortalidade do câncer colorretal. Entretanto, é importante o reconhecimento de que alguns adenomas podem não ser detectados (adenomas perdidos) durante o exame, e todos os esforços vêm sendo destinado a reduzir esta taxa. O aprimoramento das tecnologias de imagem, incluindo cromoendoscopia eletrônica e ampliação, tem sido cada vez mais adotado para melhorar a taxa de detecção de adenomas colorretais. Como exemplo, as imagens obtidas com o I-scan® (Pentax, Tóquio, Japão), que fornecem cromoendoscopia virtual em tempo real durante o exame para visão do padrão de superfície, destacando a microvasculatura da lesão detectada. As evidências sobre o impacto do uso do I-scan® na taxa de detecção de adenoma colorretal são escassas. OBJETIVO: Avaliar se o uso de imagens I-scan® (Pentax, Tóquio, Japão) tem impacto na taxa de perda de adenoma nas colonoscopias de triagem. MÉTODOS: Estudo observacional prospectivo de colonoscopias comparando cromoscopia com o aprimoramento de superfície e luz-branca. Pacientes acima de 50 anos submetidos à colonoscopia foram alocados aleatoriamente em dois grupos usando randomização eletrônica - Grupo 1: primeira inspeção com luz branca de alta definição seguida por uma segunda inspeção com o aprimoramento de superfície pelo I-scan 1®; Grupo 2: primeira inspeção com o aprimoramento de superfície I-scan 1® seguida de uma segunda inspeção com luz branca de alta definição. O desfecho primário foi a taxa de perda de adenomas do primeiro exame, calculado com o número de adenomas detectados na segunda inspeção do exame dividido pelo número total de adenomas detectados em ambas inspeções. RESULTADOS: Participaram do estudo 85 pacientes, sendo excluídos 14, com amostra final de 71 pacientes. 34 foram alocados para o Grupo 1 e 37 no Grupo 2. Um total de 58 adenomas foram detectados, 40 na primeira inspeção (20 em cada grupo) e 18 na segunda inspeção, somente no Grupo 1. A taxa de perda de adenoma foi maior para o Grupo 1 do que para o Grupo 2 (47,4% vs 0% P=0,0002). CONCLUSÃO: A utilização de aprimoramento de superfície I-scan 1 reduz a taxa de perda de adenomas em exames colonoscópios.
ABSTRACT
RESUMEN El artículo aborda uno de los elementos metodológicos de usual declaración en los proyectos de investigación: el carácter retrospectivo o prospectivo de los estudios. Se propone utilizar como criterio de clasificación, para considerar si un estudio es de un tipo o del otro, la relación que se establece entre el momento en que se diseña la investigación, por una parte, y el momento de la ocurrencia del hecho que se pretende investigar, por la otra. A partir de este criterio, se fundamenta que tanto los estudios de casos y controles como los estudios de cohortes pueden ser realizados retrospectivamente o de forma prospectiva.
ABSTRACT The article addresses one of the methodological elements commonly declared in research projects: the retrospective or prospective nature of the studies. It is proposed to use as a classification criterion, to consider whether a study is of one type or the other, the relationship established between the moment in which the investigation is designed, on the one hand, and the moment of the occurrence of the fact that is pretends to investigate, on the other. Based on this criterion, it is based that both case-control studies and cohort studies can be carried out retrospectively or prospectively.
ABSTRACT
RESUMEN Fundamento: la enfermedad cerebrovascular es en la actualidad uno de los problemas de salud más importantes, tanto en países desarrollados como subdesarrollados. Objetivo: valorar el grado de independencia funcional alcanzada en el proceso de rehabilitación en pacientes geriátricos con ictus isquémico según los factores pronósticos presentes. Métodos: se realizó un estudio prospectivo en pacientes geriátricos en la sala de rehabilitación del policlínico Santa Clara de enero de 2017 a diciembre de 2018 con diagnóstico clínico y radiológico de ictus isquémico. El universo de estudio estuvo constituido por 31 pacientes, se identificaron los factores pronósticos y se aplicó el Índice de Barthel al inicio y final de realizar el tratamiento neurorehabilitador. En el análisis estadístico se utilizaron pruebas no paramétricas, independencia basada en la distribución chi cuadrado y para muestras relacionadas, homogeneidad marginal. Resultados: predominaron los pacientes con edad entre los 60 y 69 años del sexo masculino. Los factores pronósticos encontrados en mayor frecuencia fueron la afectación del hemisferio dominante, retracciones osteotendinosas, desarrollo psicológico negativista y la colaboración pasiva. Previo al tratamiento en pacientes con menos de dos factores pronósticos, predominó la dependencia leve y al final se igualan los dependientes leves e independientes, en los pacientes con dos o más factores, al inicio del tratamiento predominaron los dependientes moderados y al final los dependientes leves. Conclusiones: la rehabilitación neurológica mejoró en la independencia de las actividades de la vida diaria de los pacientes geriátricos con ictus isquémico, que se hace más evidente cuando este se asocia a menos de dos factores pronósticos.
ABSTRACT Background: cerebrovascular disease is currently one of the most important health problems, both in developed and underdeveloped countries. Objective: to value the grade of functional independence reached in the rehabilitation process in patient geriatrics with ischemic ictus according to the factors present presage. Methods: a prospective study was carried out in geriatric patients in the rehabilitation room of the Santa Clara Polyclinic from January 2017 to December 2018 with a clinical and radiological diagnosis of ischemic ictus. The study universe was constituted by 31 patients, the prognostic factors were identified and the Barthel Index was applied at the beginning and end of the neuro-rehabilitation treatment. In the statistical analysis, nonparametric tests were used. (Independence based on the Chi square distribution and for related samples, marginal homogeneity). Results: male patients with age between 60 and 69 years of age are predominant. The prognostic factors found most frequently were the involvement of the dominant hemisphere, osteotendinous retractions, negative psychological development and passive collaboration. Prior to treatment, in patients with less than two prognostic factors, mild dependence predominated and in the end mild and independent dependents are equalized; in patients with two or more factors, moderate dependents predominated at the start of treatment and mild dependents at the end. Conclusions: neurological rehabilitation improves independence in the activities of daily life of geriatric patients with ischemic ictus that becomes more evident when this is associated with less than two prognostic factors.
ABSTRACT
Abstract A randomized, blind and prospective clinical trial was conducted to compare two clinical rehabilitation protocols in patients submitted to orthognathic surgery, during the first 60 days after surgery. Pain, edema, mandibular movement, masticatory efficiency and quality of life were evaluated. Nineteen (19) patients were separated into control and experimental groups. The control group consisted of 10 patients followed by oral and maxillofacial surgeons and submitted to a rehabilitation protocol that involved active and passive mouth opening exercises. The experimental group had 9 patients and followed the surgeons' protocol, in addition to an Early Recovery After Surgery (ERAS) protocol performed by speech therapists, and involving specific motricity exercises and lymphatic drainage. The Student's t-test was applied to compare the results, and the Fisher's exact test of independence, to analyze the quality of life and the masticatory efficiency variables. The statistical significance was set at 5% (p < 0.05) for all the tests. The results showed that the ERAS protocol made a positive difference in pain perception in the first 14 days. However, it did not improve the other variables. Although many variables showed no significant difference, it was concluded that the surgeons can delegate patient rehabilitation to qualified professionals, so that they can optimize their postoperative clinical time.

Objective:To perform a prospective cohort study to identify individual susceptibility of glucocorticoid (GC) -associated osteonecrosis of the femoral head (GA-ONFH) and their clinical and genetic risk factors. Methods:The present prospective cohort study enrolled patients who received their first GC therapy between July 2015 and January 2018 at Zhongshan Hospital. All patients did not receive any GC treatment before enrollment. Further, they planned to start GC treatment with the dose (equivalent prednisone) of ≥30 mg/d, lasted ≥3 weeks, or pulse dose ≥200 mg/d, lasted ≥3 d. Blood samples were collected before GC treatment to evaluate bone metabolism and its released factors. Hip MRI was performed at the 1st, 3rd, 6th, 12th and 24th month to diagnose GA-ONFH. All patients were followed-up for ≥2 years. The endpoint was regarded as diagnosis of GA-ONFH or completion of 2 years follow-up. Lasso regression was performed to determine which clinical features were associated with GA-ONFH. A nested case-control sub-cohort (A, n=12) was established prospectively based on the main cohort by 1∶1 matching. Whole exome sequencing was performed to screen differential and functional candidate single nucleotide polymorphisms and insertion-deletions (SNP/InDels). Another sub-cohort (B, n=50) was constructed retrospectively in patients with GA-ONFH and non-ONFH patients received standard high dose GC treatment for more than two years. The candidate SNP/InDels were verified by Sanger sequencing based on the patients from sub-cohort B. Results:A total of 96 patients were enrolled of which 88 of them (32 males and 56 females, mean age 42.30 years) completed follow-up. Eight cases (9.1%) were diagnosed with GA-ONFH. The median time from the start of GC therapy to the diagnosis of ONFH was 53.00(34.00,13.50) days. The baseline characteristics, such as age, sex and body mass index, indicated no significant difference between the ONFH group and the non-ONFH group. The cumulative GC dose of the ONFH patients in the first month was higher than that of non-ONFH [32.74(29.55, 47.05) mg/kg vs. 24.00(21.10, 29.45) mg/kg, Z=-2.410, P=0.016]. However, there was no significant difference of patients who underwent pulse therapy (37.5% vs. 10.0%, adjusted χ 2=2.829, P=0.093). The ratio of serum apolipoprotein B/apolipoprotein A1 (ApoB/ApoA1) in patients with ONFH was higher than that in non-ONFH group before GC use [0.95(0.80, 1.50) vs. 0.70(0.60, 0.80), Z=-2.875, P=0.000]. Due to the multicollinearity, Lasso regression model was performed to reduce overfitting. All variables were included in the model. The results suggested that higher ApoB/ApoA1 ratio, lower serum β-c-terminal telopeptide (β-CTX) and higher cumulative GC dose in the first month were the top three risk factors of GA-ONFH. This model had an accuracy of 0.982 in internal validation. Seven differential candidate SNP/InDels were found by whole exome sequencing of sub-cohort A. We further verified these SNP/InDels in sub-cohort B. The patients with COLEC12 mutation (rs2305027, G1816A) were at risk of GA-ONFH ( OR=6.00, 95% CI: 1.17, 30.73). Conclusion:Higher first-month GC dose, lower serum β-CTX level before treatment, higher ApoB/ApoA1 ratio and COLEC12 mutation (rs2305027, G1816A) could increase the risk of GA-ONFH.
ABSTRACT
Objective@#To explore the prospective effect of dietary intake of total fat and fatty acids on menarcheal timing among girls,and to provide a theoretical basis for preventing the early puberty development of Chinese children.@*Methods@#Using the data from 1997-2015 China Health and Nutrition Survey (CHNS), 1 240 girls aged 6-13 with menarche information, baseline dietary survey data and at least one follow up assessment were selected. Cox regression analysis was performed to examine the prospective effect of dietary intake of total fat and fatty acids before menarche on age at menarche.@*Results@#The mean baseline age of the participants was (8.3±1.8). After adjustment for year of birth, residence, household income, dietary energy intake and body mass index Z score at baseline, girls in the highest quartile of intake of total fat and polyunsaturated fatty acid (PUFA) had a 30% and 34% higher probability of experiencing menarche at an earlier age than those in the lowest quartile [ HR(HR 95%CI )=1.30 (1.01~1.68)，1.34(1.05~1.70)]. After adjusting for the confounders, there were no correlations between the intake of saturated fatty acid (SFA) and monounsaturated fatty acid (MUFA) and the onset of menarche [ HR(HR 95%CI )=1.24(0.98~1.58),1.25(0.97~ 1.62 )]( P >0.05).@*Conclusion@#Higher dietary intake of total fat and PUFA before menarche may lead to earlier age at menarche and no correlation between intake of SFA and MUFA before menarche with age at menarche is found among Chinese girls.
ABSTRACT
Objective@#To investigate the effects of orthokeratology lenses and frame glasses on anisometropia in children with low myopia in one eye.@*Methods@#Between January 2017 and January 2018, 120 children of primary and secondary school age with myopic anisometropia low myopia in one eye presenting to the Second People s Hospital of Yunnan Province were selected as research objects,with average refractive error of(-1.00,-2.50)D in one eye and(-0.50,0.50)D in another eye. Participants were divided into an experimental group and a control group (60 cases per group), according to a random number grouping method. The control group were given frame glasses, while the experimental group were given orthokeratology lenses. A prospective study was conducted to compare and analyze the lengths of the posterior eye axis (AL) and spherical equivalent (SE), measured at different time intervals between the two groups.@*Results@#There were some initial differences in AL and SE between the two groups before the experiment began; however, this difference was not statistically significant (P>0.05). After 12 months, participants myopic eyes given the orthokeratology lenses had shorter AL[(24.91±0.11)mm] compared to the control group[(25.02±0.09)mm],participants health eyes had longer AL[(24.58±0.24)mm] compared to the control group[(24.20±0.13)mm]. One month after the subjects stopped wearing plastic mirrors,participants myopic eyes had higher SE[(-2.22±0.78)D] compared to the control group[(-2.64±0.21)D],and had lower that in the control group[(-0.96±0.84)(-0.37±0.54)D](t=4.02，-4.58，P<0.05).@*Conclusion@#In children with low myopia in one eye, compared with wearers of frame glasses, wearing corneal shape lenses can effectively restrain AL extend and control the progression of eye myopia. At the same time, wearing corneal shape lenses can promote contralateral healthy eye axial extension and an increase in diopter, reduce the anisometropia value, solve the problems of a binocular visual axis development imbalance, and promote coordinated eye development.
ABSTRACT
Objective@#To examine the prospective association between peripubertal diet quality and pubertal timing.@*Methods@#Multivariate regression analyses were performed using data obtained from 1 588 SCCNG (Southwest China Childhood Nutrition and Growth) study participants, which included dietary data, anthropometric parameters, and information about potential confounders during peri puberty, two and four years before the onset of menarche or voice break. Dietary intake in peri puberty was assessed using a validated food frequency questionnaire. Diet quality was determined using the Chinese Children Dietary Index (CCDI), which measures adherence to current dietary recommendations. Age at menarche or voice break (M/VB) were used as pubertal markers.@*Results@#The CCDI score ranged from 58.0 to 132.5 for girls and from 48.3 to 129.9 for boys. The pubertal markers consistently indicated that girls and boys with a higher peripubertal diet quality entered puberty later than their counterparts with lower CCDI scores (higher vs. lower CCDI tertiles: age at M was 13.1 years (11.2-13.3) and 12.5 years (12.0-13.9)(P<0.01); VB was 13.8 years (12.1-14.8) and 13.4 years (12.5-15.1)（P=0.03), after adjusting for paternal education level, energy intake, and pre pubertal body fat.@*Conclusion@#Children with a higher diet quality during peri puberty entered puberty at a later age. Dietary guidance and intervention are needed for better dietary quality among children during pubertal transition.
