Impact of Mobile Application Intervention: DETAK in Early Detection and Early Treatment of Acute Coronary Syndrome

@#Introduction: Acute Coronary Syndrome (ACS) is still a major cause of mortality and morbidity globally. One of the factors that cause a prehospital delay is the delay in early detection and inaccuracy of early treatment of ACS. The Internet of Things, which is supported by the high use of smartphones with the DETAK application, can be an opportunity to facilitate ACS education programs so that ACS can be detected early. Method: This study has used a quantitative research design with a quasi-experimental approach which pretest and posttest, in which both the experimental and control groups participate. The inclusion criteria of this study were age >45 years; obesity; smoker; Respondents with a history of: hypertension/diabetes mellitus/hyperlipidemia/hypercholesterolemia/CVD/families with cardiovascular disease. 252 respondents who met the inclusion criteria were randomly divided into control (n=126) and intervention groups (n=126). The intervention group was given education through the DETAK application and the control group was given leaflet about ACS. Results: The results of the study showed that there was an increased in early treatment ability was only found in the intervention group (p<.001). Mean differences of the ability of early detection (p<.001) and early treatment (p=.019)between intervention and control groups were both significance. Conclusion: There is potential for DETAK applications to improve the early detection and treatment capabilities of ACS.

Factores precondicionantes de secuelas en niños menores de 5 años de edad con tortícolis muscular congénita / Precondicionant factors of sequela in children under 5 years with congenital muscular wryneck

Introducción: El espectro de secuelas de la tortícolis muscular congénita es amplio. Algunos niños con dichas secuelas requieren de costosas y complejas operaciones. Objetivo: Determinar los factores precondicionantes asociados a secuelas orgánicas de la tortícolis muscular congénita en pacientes desde un mes hasta 5 años de edad. Métodos: Se realizó un estudio retrospectivo, analítico, no experimental de casos y controles que incluyó a niños con diagnóstico de tortícolis muscular congénita, atendidos en la consulta de Neurodesarrollo del Hospital Infantil Antonio María Beguez César de Santiago de Cuba, desde enero del 2017 hasta diciembre del 2020. El grupo de casos quedó conformado por todos los pacientes con complicaciones orgánicas de la tortícolis muscular congénita (24 niños) y el de control, por quienes no presentaron dichas complicaciones (72), seleccionados mediante un muestreo aleatorio simple. Resultados: El sexo masculino predominó en los pacientes con complicaciones (62,5 %). La plagiocefalia y la asimetría facial fueron las secuelas más frecuentes. La edad menor de 6 meses en el momento del diagnóstico de la entidad constituyó un factor protector (OR = 0,12; IC 95 %: 0,04-0,33; p=0,000); hubo asociación de las complicaciones con el parto distócico (OR = 0,36; IC 95 %: 0,13-1,01; p=0,049) y con la macrosomía fetal (OR = 5,7; IC 95 %: 1,44-22,2; p=0,014). También existió asociación altamente significativa de las complicaciones con la asimetría de ambos músculos esternocleidomastoideos (OR = 11,4; IC 95 %: 3,7-34,9; p=0,000) y con el inicio tardío del tratamiento (OR = 8,5; IC 95 %: 3,0-24,1; p=0,000). Conclusiones: El parto distócico, la macrosomía fetal, la asimetría entre ambos músculos esternocleidomastoideos y el inicio tardío del tratamiento rehabilitador incrementaron el riesgo de complicaciones en los integrantes de la casuística.

Introduction: The spectrum of sequela of the congenital muscular wryneck is wide. Some children with these sequela require expensive and complex operations. Objective: To determine the precondicionant factors associated with organic sequela of the congenital muscular wryneck in patients since one month to 5 years. Methods: A retrospective, analytic, non experimental of cases and controls study was carried out that included children with diagnosis of congenital muscular wryneck, assisted in the Neurodevelopment Service of Antonio María Beguez Cesar Children Hospital in Santiago de Cuba, from January, 2017 to December, 2020. The group of cases was conformed by all the patients with organic complications of the congenital muscular wryneck (24 children) and the control group, for those who didn't present these complications (72), selected by means of a simple random sampling. Results: The male sex prevailed in the patients with complications (62.5 %). The plagiocephaly and the facial asymmetry were the most frequent sequela. The age under 6 months in the moment of the diagnosis of the entity constituted a protective factor (OR = 0.12; IC 95 %: 0.04-0.33; p=0.000); there was association of the complications with the dystocic childbirth (OR = 0.36; IC 95 %: 0.13-1.01; p=0.049) and with the fetal macrosomia (OR = 5.7; IC 95 %: 1.44-22,2; p=0.014). There was also highly significant association of the complications with the asymmetry of both sternocleidomastoid muscles (OR = 11.4; IC 95 %: 3.7-34.9; p=0-000) and with the late beginning of the treatment (OR = 8.5; IC 95 %: 3.0-24.1; p=0.000). Conclusions: The dystocic childbirth, fetal macrosomia, asymmetry between both sternocleidomastoid muscles and the late beginning of the rehabilitative treatment increased the risk of complications in the members of the case material.

Tocilizumab is useful for coronavirus disease 2019 patients: the key point is timing

SUMMARY OBJECTIVE: In coronavirus disease 2019, a rapidly progressive inflammatory process is considered to be the main cause of organ damage and mortality. Therefore, the importance of anti-inflammatory treatments such as tocilizumab is increasing. METHODS: A total of 107 patients who received tocilizumab between March 2020 and March 2021 were included in the study. The primary termination point was mortality. We compared surviving and deceased patients by the stage of the disease and where the drug was given (service or intensive care unit). RESULTS: The mean age was 60.8±14.6 years (minimum 29 years, maximum 96 years). According to the WHO staging system, 16 (15%) patients had moderate, 47 (43.9%) patients had severe, 44 (41.1%) patients had a critical illness. Although all patients were admitted to the service, 26 (24.3%) patients received tocilizumab in the intensive care unit. Of 107 patients, 80 (74.7%) survived and 27 (25.2%) died. Mortality was found to be significantly higher in critical patients (96.3%), severe patients (3.7%), and moderate patients (0%) (p<0.001). Peripheral oxygen saturation measured at admission was found to be significantly lower in patients who died. The initial saturations (p=0.008) were found to have independent effects on mortality. CONCLUSION: The results showed that tocilizumab is an effective treatment option for coronavirus disease 2019 disease and reduces mortality, but the key point is timing.

China experts' consensus on preventive and interceptive orthodontic treatments of malocclusions of children / 华西口腔医学杂志

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.

China guideline for the screening, early detection and early treatment of colorectal cancer (2020, Beijing) / 中华肿瘤杂志

Colorectal cancer (CRC) is a major malignancy threatening the health of people in China, which also leads to heavy social burden. A large number of researches and practices have demonstrated that screening and early detection are effective in reducing the mortality of CRC. It is therefore imperative to design guidelines for the screening, early detection and early treatment of CRC that are in line with national conditions of China based on international guideline development standard. In 2020, under the leadership of the National Cancer Center of China, a multidisciplinary guideline development group was established. The development of the guideline followed the principles and methods recommended by the World Health Organization. The guideline provides detailed recommendations for thirteen key clinical questions to which the professionals who are involved in screening, early detection and early treatment of colorectal cancer paid close attention. The guideline is intended to serve as a tool for professionals providing best decision-making on screening, early detection and early treatment of CRC and to enhance the effectiveness of CRC prevention and control in China.

Expert consensus of Oncology Committee of Chinese Medical Association in early diagnosis and treatment of pancreatic cancer / 中华肿瘤杂志

Pancreatic cancer(PC) remains one of the most challenging malignant tumor in gastrointestinal cancer, and the incidence and mortality rates are significantly increased in the past decades. The 5-years survival rate of PC is less than 8% since its dormant clinical symptoms and lacking of sensibility and specificity markers in early diagnosis. The early diagnosis of pancreatic cancer is a worldwide problem, and the early diagnosis rate is only 5%. Increasing early diagnosis rate is the key to improve the overall prognosis of pancreatic cancer. The key of early diagnosis and treatment of pancreatic cancer is to identify the high-risk population of pancreatic cancer, improve the sensitivity and specificity of early diagnosis technology, standardize the process of early diagnosis of pancreatic cancer, and standardize the treatment of early pancreatic cancer. To this end, this expert consensus is formulated.

Acute Stanford Type A Aortic Dissociation with Simultaneous Cerebral Hemorrhage : a Rare Case / 日本心臓血管外科学会雑誌

The case concerns a seventy-one-year old male patient on maintenance dialysis. He experienced chest discomfort and called for emergency conveyance. He was diagnosed with acute Stanford type A aortic dissection with open false lumen and expanded hematoma around the aorta using computed tomography (CT). The patient was referred to our hospital for emergent surgical intervention. At the time of admission to our hospital, cerebral hemorrhage in the left thalamus and right head of caudate nucleus was revealed on a CT head scan. On neurologic examination, a slight drop in exercise ability was demonstrated in the right arm. We shared the images offline with a neurosurgeon in a neighboring hospital. After the consultation, surgery for the acute aortic dissociation was canceled due to concerns about cerebral hemorrhage aggravation with the use of an intraoperative anticoagulant. Although there was no indication for surgical intervention for the cerebral hemorrhage at that point, he was placed under careful observation. Hemodialysis using nafamostat mesilate was restarted ; fortunately, there was no exacerbation in the cerebral hemorrhage. However, a CT scan revealed expansion of the false cavity of the ascending aorta on the fifth day post-diagnosis. After confirming no exacerbation of cerebral hemorrhage on CT on the fifth, sixth, and seventh days, graft replacement of the ascending aorta and concomitant aortic valve replacement for aortic valve stenosis were performed on the eighth day. He was extubated on the first postoperative day. He left the ICU on the sixth postoperative day. Neither increase of hematoma on the postoperative CT, nor any exacerbation of the neurologic symptoms was observed. On the forty-seventh postoperative day, he was shifted back to the referring hospital for rehabilitation.Acute aortic dissection with simultaneous onset of cerebral hemorrhage is very rare. Though both conditions are critical, there are no guidelines for treatment, and decisions on the treatment strategy are unclear. In this case of acute Stanford type A aortic dissection, there was a concern about the exacerbation of cerebral hemorrhage with the use of an intraoperative anticoagulant. We report the successful surgical repair of acute aortic dissection one week after onset as a viable therapeutic option in cases where emergency intervention is not possible due to associated complications.

Una revisión sistemática / Terapia de Tração Extraoral Cervical no Tratamento Precoce da Maloclusão Classe II. Uma revisão sistemática

Abstract Introduction and objective: Cervical headgear has been used for decades as a treatment of class II malocclusion. Although the effects have been reported previously they are somewhat contradictory. The objective was to determine the available scientific evidence that supports the parameters of clinical use for therapy with cervical extraoral traction in early treatment for class II malocclusion. Materials and methods: A systematic search was conducted using Medline, Google Scholar, Cochrane, and Lilacs data-bases. The search involved articles in English, Spanish, Portuguese, and German using previously selected MeSH terms and free-text terms. The search included articles dealing with cervical extraoral traction treatment, systematic reviews, meta-analysis, clinical trials, and cohort, case-control, and cross-sectional studies. Methodological quality was evaluated using various scales according to the type of study. Results: The search generated 334 articles, 259 were eliminated because they were duplicates, and 34 were eliminated because they did not meet the inclusion criteria. 41 articles were evaluated in full text, 21 were excluded because they did not meet the inclusion criteria, leaving a total of 20 articles. Conclusions: The articles offered varied, yet clear, recommendations. According to the literature and clinical judgment, treatment timing is recommended during the pubertal growth spurt. The most efficient force is 450 to 500g per side for 12 to 14 hours per day. A long outer bow bent 15o degrees upward should be used in patients with normal and hypodivergent patterns. Maxillary growth control depends on age, force, treatment duration, etc. Changes in overjet can be expected due to changes in dental inclination, growth, or the use of additional appliances; an average molar distalization of 1 mm to 2 mm can be achieved.

Neonatal Intensive Care Unit-based screening program for retinopathy of prematurity and its treatment in an Indian population

Purpose: The purpose was to study the incidence, risk factors, and anatomical outcomes after laser treatment in retinopathy of prematurity (ROP). Methods: A retrospective observational study was carried out. Infants admitted to Neonatal Intensive Care Unit of 12 referral hospitals between April 2016 and September 2017 were screened according to the latest Indian guidelines based on the International Classification of Retinopathy of Prematurity. Results: The incidence of ROP in 1648 eyes screened was 25.36% (418 eyes), out of which high-risk prethreshold ROP (type 1) was observed in 9.95% (164 eyes). Decreased hemoglobin (P < 0.001), oxygen requirement (P = 0.008), and number of blood transfusions (P = 0.037) were significant with type 1 than type 2 (low-risk prethreshold) ROP. Stages 1, 2, and 3 were observed in 82 (32.28%), 154 (60.62%), and 18 (7.08%) eyes, respectively. Aggressive posterior ROP (APROP) was observed in 20.73% eyes with type 1 ROP. Ten eyes showing APROP were treated at an early gestational age of 29 weeks. All infants with type 1 ROP were treated with laser photocoagulation only. Conclusion: One-fourth of the infants showed ROP and one-tenth needed laser photocoagulation, the outcome of which was excellent. Risk factors predisposing to ROP were anemia, high oxygen supplementation, increased number of blood transfusions, and septicemia. ROP screening in infants ?1700 g birth weight associated with various systemic risk factors may be beneficial in the Indian population.

A new transition of the screening, early diagnosis and early treatment project of the upper gastrointestinal cancer: opportunistic screening / 中华预防医学杂志

The screening, early diagnosis and early treatment project of the upper gastrointestinal cancer had achieved good results since its launch. However, from a national perspective, the endoscopic screening of upper gastrointestinal cancer was still not optimistic, such as the poor rate of the early diagnosis, the low rate of 5-year survival in rural areas, and the disparity of the standardized screening and diagnosis in different areas. Therefore, the situation of upper gastrointestinal cancer prevention and treatment is still severe. Under the guidance of the "Healthy China 2030" plan, based on the international experience and domestic actual circumstance, it is suggested that the screening of high-risk population in high-risk areas should be changed into the opportunistic screening in primary medical institutions. The opportunistic screening could expand the coverage of the screening, early diagnosis and early treatment project of the upper gastrointestinal cancer, and increase the early diagnosis rate in rural areas and primary medical institutions, which could improve the 5-year survival rate of patients with the upper gastrointestinal cancer, and then achieve the sustainable development of the cancer prevention and treatment in China.

Vertical Play of Straight Wire Appliance Aids Correction of Gummy Smile and Bimaxillary Incisor Proclination with Mini Implant Anchorage

@#This report aimed to describe an effective biomechanics to control the upper incisors inclination during the correction of gummy smile with bimaxillary proclinations. A 14-year-old female presented with a Class II division I incisor relationship complicated with bimaxillary proclination on a Class 2 skeletal base. The lips were incompetent, showing 7 mm of upper incisors at rest and 5mm maxillary gingival display on smiling with normal upper lip length. Treatment involved extraction of all first permanent premolars followed by upper and lower fixed appliances. Intrusion of the upper incisors with controlled labial crown torque was accomplished with mini-implant anchorage placed bilaterally on the infrazygomatic crests with the retraction forces above the centre of resistance using 0.019x0.025-in stainless steel archwire in 0.022-in slot. The 0.019x0.025-in stainless steel archwire in 0.022-in slot provided the vertical play to favour lingual crown tipping despite having forces above the centre of resistance for concurrent anterior segment intrusion.

Efficacy of esophageal cancer screening in high risk population: results of 105 561 subjects in Sichuan province / 中华肿瘤杂志

Objective@#To analyze the efficacy of endoscopic screening for esophageal cancer in high risk population from high risk areas in order to provide scientific basis for evaluation of the results of early diagnosis and treatment of esophageal cancer.@*Methods@#Ten high incidence cities and counties of esophageal cancer in Sichuan province were included in this study. Subjects aged 40-69 years were selected to participate in the endoscopic screening based on the cluster sampling, and the screening-positive subjects were further confirmed by pathological examination.@*Results@#A total of 105 561 subjects were screened during 2006—2014 in 10 cities and counties in Sichuan Province. The detection rate of precancerous lesions was 5.53% (5 841/105 561), and the positive detection rate was 1.13% (1 193/105 561). The overall detection rates of low-grade hyperplasia, moderate hyperplasia, high-grade hyperplasia/carcinoma in situ, early esophageal cancer and invasive carcinoma were 3.87% (4 089/105 561), 1.66% (1 752/105 561), 0.77% (816/105 561), 0.08% (84/105 561) and 0.28% (293/105 561), respectively. The detection rates of all lesions in males were significantly higher than those in females (P<0.05), and were gradually increased with age (P<0.05).@*Conclusions@#At these ten cities and counties in Sichuan Province with high incidence of esophageal cancer, the endoscopic screening has good effect. There are considerable numbers of patients aged 40-69 with precancerous lesions from the high risk areas. Improving the follow-up work of the population with precancerous lesions will achieve better results of early diagnosis and early treatment.
