An evaluation of the awareness, perceptions, and practice of ultrasound and the use of telesonography among obstetrics and gynecologic sonologists in the Philippines during COVID-19 pandemic / Philippine Journal of Obstetrics and Gynecology

Background@#Major changes in the practice of medicine have been adopted due to the COVID-19 pandemic and have not spared the practice of ultrasound among obstetrician–gynecologists, considered to have higher risk due to unique attributes of an ultrasound examination. @*Objectives@#This study evaluated the awareness, attitudes, perceptions, and practices of the obstetric–gynecologic sonologists in the country during the pandemic, including the use of telesonography.@*Methodology@#A descriptive, cross-sectional survey was conducted through a self-administered, structured questionnaire using an online survey software. @*Results@#There were 120 respondents with postresidency training in ultrasound (54.2%) or in maternal and fetal medicine (43.3%), practicing in different regions, and mostly with teaching affiliations (56.7%). Most are aware of the guidelines on the practice of ultrasound this pandemic and they perceived themselves to be especially vulnerable to the infection. They admitted having feelings of stress, sadness, and depression, and their concerns centered on being infected and potentially transmitting it to their family. These perceptions translated to specific practices that include use of level 3 personal protective equipment, patient screening, triaging, and use of physical barriers to minimize environmental and contamination. While most are consistent with guidelines, some practices are neither based on sound scientific evidence nor correctly adhered to, including noncompliance with appropriate ultrasound transducer cleaning and disinfection. Regarding telesonography, only half of the respondents had good knowledge, with most having informal sources of information on the technology. Although the respondents have a good attitude toward it, only a few (15.8%) admitted to using it, mainly to confer with an expert or colleague (38.3%), and for teaching purposes (11.7%). @*Conclusions@#Obstetric–gynecologic sonologists in the Philippines are aware of the risks and have the same attitudes and perspective on COVID-19 infection as other health-care providers. Specific practices have been modified; however, the use of telesonography is not among the changes adopted.

An integrative Tai Chi program for patients with breast cancer undergoing cancer therapy: study protocol for a randomized controlled feasibility study / 中西医结合学报

<p><b>BACKGROUND</b>Breast cancer patients experience various side effects during cancer therapy, often resulting in reduced quality of life and poor adherence to treatment. A limited range of proven interventions has been developed to target such side effects. While Tai Chi offers benefits for the health and well-being of breast cancer survivors, the effectiveness of Tai Chi across the treatment continuum has not been evaluated. Improved patient education and support has been suggested as a priority for breast cancer care. This pilot study assesses the feasibility of a randomized controlled trial (RCT) to evaluate the effectiveness of "an integrative Tai Chi" (ANITA) program for breast cancer patients undergoing cancer therapy.</p><p><b>METHODS/DESIGN</b>This is a single-centre, two-arm feasibility RCT. Twenty-four patients with breast cancer who have undergone surgical treatment will be recruited from the Dunedin Hospital (New Zealand) over a 12-month period (from August 2017 to July 2018). Subject to informed consent, patients will be randomized to receive standard cancer treatment alone or standard cancer treatment plus the ANITA program, consisting of peer support, health education, and Tai Chi Ruler exercise. The program runs alongside the patient's adjuvant cancer therapy, which may include chemotherapy, radiation therapy, antibody treatment, and/or antihormonal therapy. Analysis in this study will focus on process evaluation of participant recruitment, retention, treatment fidelity, acceptability of the program, and occurrence of adverse events. Clinical outcomes (i.e., fatigue, sleep quality, anxiety and depression and quality of life) will be assessed at baseline, and at 12 weeks and 24 weeks post-randomization.</p><p><b>DISCUSSION</b>Outcomes from this study will inform the feasibility and methodology for a future fully-powered RCT.</p><p><b>TRIAL REGISTRATION</b>Australian New Zealand Clinical Trials Registry with the identifier ACTRN12617000975392.</p>

The association of layperson characteristics with the quality of simulated cardiopulmonary resuscitation performance / 世界急诊医学杂志（英文）

@#BACKGROUND: Few studies have examined the association of layperson characteristics with cardiopulmonary resuscitation (CPR) provision. Previous studies suggested provider characteristics, including age and gender, were associated with CPR quality, particularly chest compression (CC) depth. We sought to determine the association of subject characteristics, including age and gender with layperson CPR quality during an unannounced simulated CPR event. We hypothesized shallower CC depth in females, and older-aged subjects. METHODS: As part of a larger multicenter randomized controlled trial of CPR training for cardiac patients' caregivers, CPR skills were assessed 6 months after training. We analyzed associations between subject characteristics and CC rate, CC depth and no-flow time. Each variable was analyzed independently; significant predictors determined via univariate analysis were assessed in a multivariate regression model. RESULTS: A total of 521 laypersons completed a 6-month CPR skills assessment and were included in the analysis. Mean age was 51.8±13.7 years, 75% were female, 57% were Caucasian. Overall, mean CC rate was 88.5±25.0 per minute, CC depth was 50.9±2.0 mm, and mean no-flow time was 15.9±2.7 sec/min. CC depth decreased significantly in subjects >62 years (P<0.001). Male subjects performed deeper CCs than female subjects (47.5±1.7 vs. 41.9±0.6, P<0.001). CONCLUSION: We found that layperson age >62 years and female gender are associated with shallower CC depth.

Presentación atípica de meningioma de células claras en cauda equina sin implantación dural / Atipic presentation of nondura-based clear cell meningioma in cauda equina

Introducción: El Meningioma de Células Claras (MCC) es un raro subtipo de meningioma. Se han descrito más de 100 casos de MCC a nivel mundial, de ellos sólo se han publicado 17 con duramadre indemne, presentándose generalmente en mujeres jóvenes. El objetivo es presentar un caso clínico inusual y atípico, conociendo manejo y pronóstico. Presentación del caso: Se trata de un varón de 75 años con antecedentes de hipertensión arterial y leucemia linfoide crónica en tratamiento, que consultó por dolor polirradicular y paresia de extremidades inferiores con posterior compromiso esfinteriano. La resonancia nuclear magnética de columna evidenció un tumor intradural a nivel de L1-L3. Se realizó exéresis tumoral bajo neuromonitoreo, observándose un tumor amarillo-grisáceo adyacente al cono medular y a la cauda equina, sin afección de la duramadre. El estudio histológico e inmunohistoquímico demostraron MCC. El paciente evolucionó con regresión completa de su sintomatología preoperatoria. Discusión: En la cauda equina, incluso sin implantación dural, debe plantearse la posibilidad de un meningioma, enfatizando en la resección completa de la lesión a causa del fuerte factor predictor de recidiva.

Introduction: The Clear Cell Meningioma (CCM) is a rare subtype of meningioma. Have been reported more than 100 cases of CCM in the world, of which only 17 cases are nondura-based CCM, more frequently in young women. The aim is to present an unusual case knowing management and prognosis. Case report: This is a man of 75 years old with a history of hypertension and chronic lymphocytic leukemia in treatment, who consulted for polirradicular pain and paresis of lower extremities with subsequent sphincteric compromise. The magnetic resonance imaging showed spinal tumor in L1-L3. Tumor resection was per-formed under neuromonitoring and observed a nondura-based tumor adjacent to the medullary cone and the cauda equina. The histological and immunohistochemical study showed CCM. The patient developed complete regression of preoperative symptoms. Discussion: In horsetail, even without dural implantation, it should consider the possibility of a meningioma, emphasizing in the complete resection of the lesion given strong predictor factor of recurrence

Impact of the 2010 resuscitation guidelines training on layperson chest compressions / 世界急诊医学杂志（英文）

@#BACKGROUND: Survival from cardiac arrest is sensitive to the quality of delivered CPR. In 2010, updated international resuscitation guidelines emphasized deeper chest compressions and faster rates, yet it is unknown whether training laypersons using updated guidelines resulted in changed CPR performance. We hypothesized that laypersons taught CPR using the 2010 guidelines performed deeper and faster compressions than those taught using the 2005 materials. METHODS: This work represents a secondary analysis of a study conducted at eight hospitals where family members of hospitalized cardiac patients were trained in CPR. An initial cohort was trained using the 2005 guidelines, and a subsequent cohort was trained using the 2010 guideline materials. Post training, CPR skills were quantified using a recording manikin. RESULTS: Between May 2009 to August 2013, 338 subjects completed the assessment. Among the subjects, 176 received 2005 training and 162 underwent 2010 training. The mean compression rate in the 2005 cohort was 87 (95％CI 83–90) per minute, and in the 2010 cohort was 86 (95％CI 83–90) per minute (P=ns), while the mean compression depth was 34 (95％CI 32–35) mm in the 2005 cohort and 46 (95％CI 44–47) mm in the 2010 cohort (P<0.01). CONCLUSIONS: Training with the 2010 CPR guidelines resulted in a statistically significant increase in trainees' compression depth but there was no change in compression rate. Nevertheless, the majority of CPR performed by trainees in both cohorts was below the guideline recommendation, highlighting an important gap between training goals and trainee performance.

Pathobiology of Paget's Disease of Bone

Paget's disease of bone is characterized by highly localized areas of increased bone resorption accompanied by exuberant, but aberrant new bone formation with the primary cellular abnormality in osteoclasts. Paget's disease provides an important paradigm for understanding the molecular mechanisms regulating both osteoclast formation and osteoclast-induced osteoblast activity. Both genetic and environmental etiologies have been implicated in Paget's disease, but their relative contributions are just beginning to be defined. To date, the only gene with mutations in the coding region linked to Paget's disease is sequestosome-1 (SQSTM1), which encodes the p62 protein, and these mutations lead to elevated cytokine activation of NF-B in osteoclasts but do not induce a "pagetic osteoclast" phenotype. Further, genetic mutations linked to Paget's appear insufficient to cause Paget's disease and additional susceptibility loci or environmental factors may be required. Among the environmental factors suggested to induce Paget's disease, chronic measles (MV) infection has been the most studied. Expression of the measles virus nucleocapsid gene (MVNP) in osteoclasts induces pagetic-like osteoclasts and bone lesions in mice. Further, mice expressing both MVNP in osteoclasts and germline mutant p62 develop dramatic pagetic bone lesions that were strikingly similar to those seen in patients with Paget's disease. Thus, interactions between environmental and genetic factors appear important to the development of Paget's disease. In this article we review the mechanisms responsible for the effects of mutant p62 gene expression and MVNP on osteoclast and osteoblast activity, and how they may contribute to the development of Paget's disease of bone.

Obesidad y mortalidad en hombres según el estado de su enfermedad coronaria / Obesity and mortality in men according to coronary heart disease status

Las pocas comunicaciones sobre la asociación de obesidad o sobrepeso con mortalidad en personas con enfermedad coronaria (EC) muestran hallazgos contradictorios. En el estudio Whitehall –en el que participaron empleados gubernamentales de sexo masculino de Londres–, 18 403 hombres de mediana edad que habían participado en un examen médico entre 1967 y 1970 fueron controlados durante 38 años. En los hombres que presentaban EC al inicio hubo pruebas de un riesgo ligeramente mayor de mortalidad por todas las causas y por EC, pero no por accidente cerebrovascular en los grupos con sobrepeso y obesidad en relación con los hombres de peso normal. Aunque estas tendencias fueron mucho más notables en los hombres sin EC al inicio del estudio, la diferencia según el estado basal de EC no alcanzó significación estadística en los niveles convencionales. Evitar la obesidad y el sobrepeso en la vida adulta tanto en hombres con EC como sin ella puede reducir el riesgo posterior de mortalidad total y mortalidad por cardiopatía coronaria.

The few reports on the association of obesity oroverweight with mortality in persons with existing coronary heart disease (CHD) reveal inconsistent findings.In the Whitehall study of London-based male government employees, 18 403 middle-age men were followed upfor up for a maximum of 38 years having participated in a medical examination between 1967 and 1970. In menwith baseline CHD, there was evidence of a modestelevated risk for mortality from all-causes and coronaryheart disease but not stroke in overweight and obesegroups relative to normal weight men. While these slopeswere markedly steeper in men who were CHD-free atstudy induction, the difference in the gradients accordingto baseline CHD status did not attain statistical significance at conventional levels. Avoidance of obesity and overweight in adult life in both men with and without CHD may reduce their later risk of total and coronary heart disease mortality.

Efeito do exercício físico sobre peso corporal em crianças com excesso de peso: ensaio clínico comunitário randomizado em uma favela no Brasil / Effect of physical exercise on bodyweight in overweight children: a randomized controlled trial in a Brazilian slum

Associação da obesidade com doenças crônicas tem se mostrado mais intensa nas áreas carentes. Examinamos o efeito de um programa de exercício físico para crianças com excesso de peso, em uma favela do Recife, Pernambuco, Brasil, por meio de um ensaio comunitário, randomizado, com 78 crianças. Um grupo (n = 39) recebeu três aulas semanais de exercícios físicos durante seis meses. Não foi realizada nenhuma intervenção em relação à alimentação. A análise por intenção de tratamento demonstrou que todas as crianças apresentaram aumento significativo de peso. Entretanto, esse aumento foi menor no grupo que sofreu a intervenção (diferença média entre os grupos; -1.37; IC95 por cento: -2,00; -0,74). Em relação ao índice de massa corporal (IMC), também foi verificada uma diferença significativa (p = 0,049) entre os dois grupos (diferença média entre os grupos; -0,53; IC95 por cento: -1,06; -0,002). Na análise restrita às crianças que completaram o estudo (intervenção = 30 e controle = 38), os resultados foram similares. Concluímos que um programa regular de exercícios físicos para crianças com excesso de peso em áreas carentes seja eficaz, sem a necessidade de intervenções dietéticas, na redução do ganho ponderal e do IMC.

Given the increase in obesity in developed and developing countries and its concomitant morbidity, successful treatment approaches are needed. We examined the effect of a structured exercise intervention in overweight children in a slum in Recife, Pernambuco State, Brazil. This was a randomized, controlled efficacy trial. Seventy-eight children were randomized. Exercise was supervised, consisting of three 50' group aerobics sessions per week for six months. All participants maintained ad libitum diets. Based on intention-to-treat analyses, children in both groups had a significant increase in weight at follow-up (p-value for within-group increase < 0.01). The increase in weight was significantly lower in the exercise group (mean difference between groups; -1.37; 95 percentCI: -2.00; -0.74). A significant difference (p = 0.049) between the exercise and control groups at six-month follow-up was also found for BMI (mean difference between groups; -0.53; 95 percentCI: -1.06; -0.002). When we restricted the analyses to children who completed the trial (intervention = 30 and control = 38), the results were the same. An exercise program for children, sustained for six months, was effective for reducing weight gain in overweight children living in a very poor neighborhood.

Distribución geográfica de mortalidad por tumores malignos de estómago, tráquea, bronquios y pulmón, Chile 1997-2004 / Geographical distribution of mortality caused by stomach, trachea, bronchi and lung malignant tumors in Chile

Background: Maps have played a critical role in public health since 1855, when John Snow associated a cholera outbreak with contaminated water source in London. After cardiovascular diseases, cancer is the second leading cause of death in Chile. Cancer was responsible for 22.7 percent of all deaths in 1997-2004 period. Aim To describe the geographical distribution of stomach, trachea, bronchi and lung cancer mortality. Material and methods: Mortality statistics for the years 1997-2004, published by the National Statistics Institute and Chilean Ministry of Health, were used. The standardized mortality ratio (SMR) for sex and age quinquennium was calculated for 341 counties in the country. A hierarchical Bayesian analysis of Poisson regression models for SMR was performed. The maps were developed using adjusted SMR (or smoothed) by the Poisson model. Results: There is an excess mortality caused by stomach cancer in south central Chile, from Teno to Valdivia. There is an excess mortality caused by trachea, bronchi and lung cancer in northern Chile, from Copiapó to Iquique. Conclusions: The geographical analysis of mortality caused by cancer shows cluster of counties with an excess risk. These areas should be considered for health care decision making and resource allocation.

El diagnóstico histopatológico final reportó embarazo ectópico tubario. Conclusiones: Una mujer con masa anexial compleja, útero vacío, elevación de marcadores tumorales y evolución poco clara puede estar cursando con embarazo ectópico crónico.

Rinoescleroma, una enfermedad rara en Chile: reporte de un caso clínico / Rhinoscleroma, a rare illness in Chile: report of a clinical case

Se presenta el primer caso publicado de rinoescleroma en un paciente chileno, con historia de tres años de evolución de obstrucción nasal izquierda que luego se hace bilateral. Es estudiado en el Policlínico de Otorrinolaringología del Hospital Barros Luco Trudeau, pesquisándose una masa en fosas nasales de aspecto polipoideo atípico. Mediante estudio histopatológico e infectológico se confirma el diagnóstico de rinoescleroma, con cultivo positivo para Klebsiella rhinoscleromatis. El paciente es tratado con moxifloxacino durante seis semanas previo a la cirugía endoscópica, efectuándose resección de la patología en ambas fosas nasales. Se trata con antibiótico durante seis semanas más, quedando, a los tres meses postcirugía, con leve obstrucción nasal a izquierda secundaria a una estenosis fibrosa de coana izquierda, residual a su patología.

[Flow cytometric survey of RBC chimerism after bone marrow transplantation]

The aim of the present study was to evaluate red blood cell chimerism after bone marrow transplantation by flow cytometry. In order to perform this assay, FITC labeled antibodies against blood groups ABH, Rh, Kell, Duffy, Kidd, MNS were used.14 hematologic patients under BMT were selected for this study. The required sample was 5 ml peripheral blood that is collected in tubes containing EDTA. At first, donor and recipients red cells phenotypes were identified with the use of both agglutination and flow cytometry methods; then, on post-transplantation days of 15, 30 and 60, only blood samples of the recipients were analyzed by flow cytometry for the antigens differing from donors to recipients. Antibody screening test and titration of ABH Isohemagglutinins were performed on recipients' plasma samples and then repeated on post-transplantation day of 60. After BMT, red cell chimerism was detected in all 14 patients [in 9 patients on post-transplantation day of 15 and in 5 patients on day of 30]. Antibodies against minor blood groups and Rh blood group were not detected at all. The occurrence of chimerism was not inhibited by ABO incompatibility of donors and recipients but in patients who were ABH incompatible with their donors, ABH isohemagglutinins titer following transplantation decreased. Although the presence of isohemagglutinins did not prevent chimerism but it seems these antibodies by attaching to their related antigens on chimeric red cells membrane prevented corresponding antigen detection. Now by using flow cytometry, red cell phenotyping is applicable and reticulocyte analysis is much easier to perform so that chimerism can be detected in patients who have recently experienced blood transfusion. Moreover, through further evaluation of red cell chimerism and detection of recipient autologous red cells, disease relapse can be predicted

Lipoma lingual en pacientes infantil: reporte de un caso / Lingual lipoma in pediatric patients: report of case

Se presenta un caso de un lipoma localizado en el dorso de la lengua, de una paciente de sexo femenino, de 8 años de edad. El lipoma es una neoplasia benigna que, a nivel general, se presenta más frecuentemente en mujeres adultas, mayores de cuarenta años. Se caracteriza por ser una tumoración de crecimiento lento, indolora, amarillenta y de superficie lisa. Rar vez se observa en la cavidad oral y, cuando existe su ubicación preferencial es una mucosa yugal y fondo del vestíbulo. Nos parece interesante presentar este caso por lo atípico de su prensentación etárea y ubicación anatómica, además, se anexa una revisión que considera aspectos epidemiológica y características clínicas e histológicas

Estudio in vitro de tres antiandrógenos empleados en la actualidad en enfermedades andrógenodependientes / In vitro assay of three antiandrogens presently used in the treatment of androgen dependent diseases

Objetivo: Analizar el efecto in vitro del acetato de ciproterona, finasteride y flutamida, sobre la enzima 5Ó-reductasa, principal indicador bioquímico responsable del potente efecto andrógenico de la tetosterona, al convertirla en dihidrotestosterona. Material y Métodos: Se midio la actividad de la enzima 5Ó-reductasa en la próstata de ratas de macho adultos, utilizando concentraciones de 20 a 500µM de cada antiandrógeno. Resultados: El análisis estadístico muestra que la flutamina presenta mejor actividad antiandrogénica a medida que se incrementa su concentración, mientras que en el acetato de ciproterona y el finasteride, el efecto antiandrogénico fue menor a diferentes concentraciones (p<0.05); probablemente por una mayor velocidad de disociación de estos compuestos con su receptor

Tumores raquídeos en pacientes pediátricos / Spinal tumors in pediatric patients

Los autores han revisado 14 casos de tumores raquídeos en pacientes pediátricos (0-15 años) controlados en el Instituto de Neurocirugía Asenjo, entre 1980 y 1992. Se encontraron diferentes tipos de tumores, sin predominar claramente ninguno de ellos, presentes también a diferentes niveles, predominando sobre todo a nivel dorsal (9 de 14 casos). La mayor frecuencia de presentación se encuentra en el grupo de edad entre 11 y 15 años y con un promedio de evolución previo a la primera consulta de 3-6 meses. Los tumores raquídeos son relativamente raros durante la infancia. En toda la literatura publicada existe controversia con los tumores raquídeos en la infancia, relacionada con el tipo de lesiones que deben ser incluídas y en relación al límite de edad considerado para el grupo pediátrico

Cáncer broncogénico: experiencia de 12 años en el Instituto Nacional de Cancerología / Bronchogenic cancer: 12 years experience in the National Institute of Cancerology

Se revisaron 629 expedientes clínicos de pacientes con diagnóstico de carcinoma broncogénico, vistos en el Instituto Nacional de Cancerología durante 12 años, de 1975 a 1986. El sexo con mayor frecuencia fue el masculino con el 70% (440 pacientes) y la edad de la 5a. a la 7a. década de la vida. El hábido tabáquico se detectó en el 80% de los enfermos (503). El tiempo de evolución del padecimiento antes de llegar al Instituto fué un promedio de 45 días. El 80% de los pacientes estaban en estado clínico III (503 pacientes). A diferencia de lo reportado en la literatura al respecto, el adenocarcinoma fue el tipo histológico más frecuente
