International student exchange and the medical curriculum: evaluation of a medical sciences translational physiology course in Brazil

The objective of the present study was to conduct a short-term international course on translational physiology for medical students from Wright State University and the University of Iowa. The goals were to 1) provide students with an exposure to the academic, cultural, and medical environments in Brazil; 2) promote awareness of the global medical community; and 3) provide an academic course focused on translational physiology. An evaluation of the students was conducted to determine whether such a short-term course might be useful in the medical curriculum. The 2-wk course was held in the summer of 2005 at the University of S?o Paulo School of Medicine in Ribeir?o Preto, Brazil, for 23 American students. The program included presentations of basic and clinical topics, meetings with medical students, and clinical presentations. The program finished with student attendance at a scientific meeting sponsored by the Brazilian Society of Hypertension. Student surveys evaluated issues related to perceived treatment, Brazilian medical school environment, culture and personal attributes, and career aspirations. The international Medical Sciences Translational Physiology course for medical students provided a brief, but intense, experience. It gave students a picture of the medical environment in Brazil and an appreciation for the differences and similarities in cultures. Most students reported that it was a positive experience that would be beneficial to their careers. In conclusion, a short-term international course provides an efficient means for medical students to experience aspects of global medical science.

Medical records for animals used in research, teaching, and testing: public statement from the American College of Laboratory Animal Medicine

Medical records are considered to be a key element of a program of adequate veterinary care for animals used in research, teaching, and testing. However, prior to the release of the public statement on medical records by the American College of Laboratory Animal Medicine (ACLAM), the guidance that was available on the form and content of medical records used for the research setting was not consistent and, in some cases, was considered to be too rigid. To address this concern, ACLAM convened an ad hoc Medical Records Committee and charged the Committee with the task of developing a medical record guideline that was based on both professional judgment and performance standards. The Committee provided ACLAM with a guidance document titled Public Statements: Medical Records for Animals Used in Research, Teaching, and Testing, which was approved by ACLAM in late 2004. The ACLAM public statement on medical records provides guidance on the definition and content of medical records, and clearly identifies the Attending Veterinarian as the individual who is charged with authority and responsibility for oversight of the institution's medical records program. The document offers latitude to institutions in the precise form and process used for medical records but identifies typical information to be included in such records. As a result, the ACLAM public statement on medical records provides practical yet flexible guidelines to assure that documentation of animal health is performed in research, teaching, and testing situations.     

Hope modified the association between distress and incidence of self-perceived medical errors among practicing physicians: prospective cohort study

The presence of hope has been found to influence an individual's ability to cope with stressful situations. The objective of this study is to evaluate the relationship between medical errors, hope and burnout among practicing physicians using validated metrics. Prospective cohort study was conducted among hospital based physicians practicing in Japan (N = 836). Measures included the validated Burnout Scale, self-assessment of medical errors and Herth Hope Index (HHI). The main outcome measure was the frequency of self-perceived medical errors, and Poisson regression analysis was used to evaluate the association between hope and medical error. A total of 361 errors were reported in 836 physician-years. We observed a significant association between hope and self-report of medical errors. Compared with the lowest tertile category of HHI, incidence rate ratios (IRRs) of self-perceived medical errors of physicians in the highest category were 0.44 (95%CI, 0.34 to 0.58) and 0.54 (95%CI, 0.42 to 0.70) respectively, for the 2(nd) and 3(rd) tertile. In stratified analysis by hope score, among physicians with a low hope score, those who experienced higher burnout reported higher incidence of errors; physicians with high hope scores did not report high incidences of errors, even if they experienced high burnout. Self-perceived medical errors showed a strong association with physicians' hope, and hope modified the association between physicians' burnout and self-perceived medical errors.     

建构主义教学模式在医学微生物学教学实践中的应用

传统的教学模式是以"教师为中心",建构主义教学模式强调"以学生为主体"。医学微生物学教学存在课时少、内容繁杂、知识点琐碎、逻辑性较差等特点,采用传统教学模式往往不能达到较好的教学效果。通过将建构主义理论引入医学微生物学教学实践中,我们设计了适合医学微生物学的建构主义教学模式,充分调动学生的主动性、积极性和创造性。该模式的应用,进一步提高了医学微生物学的教学质量,增加了学生综合素质的培养。

孕激素及人绒毛促性腺激素与药物流产后异常子宫出血的关系

目的:分析孕激素和人绒毛膜促性腺激素(h CG)与药物流产后异常子宫出血的关系。方法:选择2017年1月至2017年12月我院妇产科收治的药物终止妊娠的妇女150例,患者口服米非司酮配伍米索前列醇药物终止早期妊娠。将药物流产后子宫出血时间≤14 d作为对照组(n=75),14d作为异常组(n=75)。比较两组患者在药物流产后10 d、14 d、18 d、22 d血清中孕激素和h CG含量,分析两组患者孕激素和h CG含量相关性。结果:两组患者在年龄、月经周期、孕次、受孕天数、体重等方面比较无统计学差异(P0.05)。异常组在药物流产后10 d、14 d、18 d、22 d血清孕激素和h CG含量均高于对照组(P0.05)。两组患者在药物流产后10 d、14 d、18 d、22 d孕激素含量呈先降低再升高的趋势(P0.05)。对照组患者在药物流产后10 d、14 d、18 d、22 d血清hCG含量逐渐降低(P0.05);异常组在药物流产后10 d、14 d血清h CG含量比较无统计学差异(P0.05),在药物流产后18 d、22 d血清hCG含量低于药物流产后10 d、14 d,且药物流产后22 d低于药物流产后18 d(P0.05)。对全部样本的全部时点数据合并进行Pearson相关检验分析,孕激素和h CG含量呈正相关关系(P0.05)。结论:药物流产后异常子宫出血妇女血清的孕激素、hCG含量较高,两者呈正相关关系。药物流产后10 d、14 d监测血清HCG值无明显下降提示有异常子宫出血的可能,联合监测孕激素、hCG含量有利于药物流产后异常子宫出血的预测和治疗。     

Medical care for Russian cosmonauts on board the ISS

Established with the personal participation of O.G. Gazenko, the Russian system of medical care for cosmonauts has been largely preserved to this day. The system was fully functional on board the orbital complex Mir and, with appropriate modifications, has been adopted as the core of the medical care for Russian members of ISS crews. In 2000–2008, 22 cosmonauts were members of 17 ISS missions lasting from 140 to 216 days. The main functions of the medical care system were to control health, physical, and mental performance, and to support space research. Readaptation to normal gravity was, in most cases, similar to what has been typical on the return from Russian orbital stations; some deviations are accounted for by the use of in-flight countermeasures. The paper presents some aspects of the theoretical work of Academician Gazenko in the field of medical care in space flights. It outlines the principles of ISS medical management. The integrated medical support system combines medical equipment and items available in the Russian and U.S. segments; the integrated medical group consists of flight surgeons, medical experts, and biomedical engineers of international partners and coordinates the planning and implementation of medical operations. In addition, challenges of health care in the phase of ISS operation are defined.     

The influence of previous medical treatments on milking order in dairy cows

Animal health issues are a problem on many dairy farms, and much is already known about clinical treatments and the behaviour of sick animals. Animal health issues can influence behaviour seen around the milking parlour, but less is known about the relationship between the number of previous medical treatments and the queuing to be milked, the ‘milking order’. Information was collected on five afternoon milking sessions, the individual cows’ age and the medical treatment history of each cow in a group of 100 cows. The question addressed was whether the age and the medical treatment history of each cow in the herd affected its milking order. In addition, milking order was tested day to day, and was found to be consistent. A significant positive correlation was found between medical treatment history and milking order rank, meaning that cows with a higher medical treatment history tended to enter the milking parlour later than cows with a lower medical treatment history. In contrast with this finding, it was found that older cows were more likely to enter the milking parlour early when compared to younger animals, a finding which is supported by previous studies. These somewhat contradictory effects of (a) age and (b) medical treatment history on milking order suggest that health disorders may have long-term measurable effects on the position of a cow in the milking order, even when the effect of age on milking order is accounted for.     

Unmet need for additional medical care for sick children in mother's view in rural Bangladesh: implications for improving child health services

While a country's health policy aims to provide health services to all who need them, very little in known about unmet need for additional medical care from users' perspectives in Bangladesh. This study examined unmet medical need (defined as whether a mother felt that, to manage sickness, her child had required medical care that was not available, regardless of reasons and medical care sought) of 2123 under-15 sick children by illness and child's socioeconomic characteristics in rural Bangladesh. The 1996 Health and Socioeconomic Survey conducted in Matlab recorded children's chronic (a disease or a condition lasting 3 months or more) and acute (a disease or a condition with a rapid onset and a short, severe course) morbidity, medical care sought to combat illness and unmet needs for additional medical services in mothers' views to manage the illness. The survey also recorded household socioeconomic data. Logistic regression was used to examine the data. The results reveal that unmet needs for additional medical care were 5.4% for children with acute illnesses, and 30.2% for children with chronic illnesses. For chronic illnesses, seeking medical care to manage illness from any health provider outside the home reduced unmet medical needs. Economic inequalities existed for both acute and chronic illnesses: the odds ratio of unmet medical needs for sick children of the least poor households was 0.42 (95% CI: 0.28-0.64) times that for sick children of the very poor households. The critically high unmet needs for children's chronic morbidity reveal that the chronic disease control programme in Bangladesh needs urgent revisiting and strengthening.     

Status of nutrition education in Canadian dental and medical schools.

To investigate the present status of nutrition education for dentists and physicians in Canada, we conducted a survey of the nutrition education programs in 10 Canadian dental and 16 medical schools in the academic year 1982-83. Seven of the dental schools and seven of the medical schools had a separate course in nutrition. The average duration of these courses was 22 hours for the dental schools and 26 hours for the medical schools. Nutrition education was integrated with another discipline in 4 of the dental schools and 11 of the medical schools. The average duration of this type of instruction was 14 hours for the dental schools and 18 hours for the medical schools. Six of the dental schools and eight of the medical schools employed a nutritionist/dietitian to provide instruction in nutrition. We recommend that courses in basic and applied clinical nutrition be incorporated throughout the curricula of Canadian dental and medical schools, and that personnel trained in clinical nutrition be employed to provide instruction in this area.     

Comparisons between written and computerised patient histories.

Patient histories were obtained from 99 patients in three different ways: by a computerised patient interview (patient record), by the usual written interview (medical record), and by the transcribed record, which was a computerised version of the medical record. Patient complaints, diagnostic hypotheses, observer and record variations, and patients'' and doctors'' opinions were analysed for each record, and records were compared with the final diagnosis. About 40% of the data in the patient record were not present in the medical record. Two thirds of the patients said that they could express all or most of their complaints in the patient record. The doctors found that the medical record expressed the main complaints better (52%) than the patient record (15%) but that diagnostic hypotheses were more certain in the patient record (38%) than in the medical one (26%). The number of diagnostic hypotheses in the patient record was about 20% higher than that in the medical record. Intraobserver agreement (51%) was better than interobserver agreement (32%), while the inter-record agreement varied from 25% (between the medical and patient records) to 35% (between the transcribed and patient records). One third of final diagnoses were seen in the medical record, with 29% and 22% for the transcribed and patient records, respectively. Interobserver agreement in the final diagnosis was 35%. The results of the study suggest that computerised history taking is suitable for certain patients in addition to, and not as a substitute for, the oral interview with a doctor.     

Investigation on psychological state of occupational exposure of medical staff in operation room under novel coronavirus

This article mainly explores the psychological state of occupational exposure of medical staff in operation room contaminated with novel coronavirus, and provides targeted suggestions for mental health service of medical staff so as to maintain their physical and mental health. On February 28, 2020, a questionnaire survey was conducted using Internet. Nurses, anesthesiologists and surgeons in the operating room of the First Affiliated Hospital of Harbin Medical University from January 2020 to March 2020 were selected as the research objects. The psychological state of medical staff was investigated by SAS and PSS-14. As on February 29, 2020, 301 valid questionnaires and one invalid questionnaire were received. The survey showed that there was anxiety but no moderate or severe anxiety in the occupational behavior of operating room medical staff, while some medical staff had a certain degree of psychological pressure (P < 0.05). The present survey suggested that medical staff was under anxiety and pressure in different degrees in the operation room because of novel coronavirus contamination during occupational activities, much attention is required to improve mental health of medical professionals and to reduce their negative emotions.     

Exclusion of deceased donors post-procurement of tissues

The EU Tissues and Cells Directive (2004/23/EC, 2006/17/EC, 2006/86/EC) (EUTCD) provides standards for quality and safety for all aspects of banking of tissues and cells for clinical applications. Commission Directive 2006/17/EC stipulates that the complete donor record with all the medical information is assessed for suitability before releasing tissues for clinical use. The aim of this study was to investigate the medical reasons for post-procurement donor exclusion, to identify the various potential sources for gathering information about donors’ medical and behavioural history and to evaluate their contribution to maximising the safety of donations. Information was collected from the Tissue Services (TS) records of 1000 consecutive deceased donors submitted to National Health Service Blood and Transplant (NHSBT) medical officers for authorisation for release for subsequent tissue processing and then for transplantation. Of the 1000 donors 60 (6%) were excluded because they did not fulfil the donor selection requirements of the EUTCD and NHSBT donor selection guidelines. The main reasons for medical exclusion were the presence of significant local or systemic infection in 32 donors (53% of those excluded for medical reasons) and a history of past or occult malignancy in 9 donors (15% of those excluded for medical reasons) which was not identified prior to procurement. The information leading to post-procurement exclusion was obtained from autopsy reports in 35 of the 60 excluded donors for medical reasons (58%) and from the general practitioner for 10 donors (17% of those excluded for medical reasons). In summary, careful evaluation of complete donor records reduces the potential risk of disease transmission by tissue allografts and ensures compliance with regulations and guidelines. The findings may lead to changes in donor selection policies with the aim of improving efficiency without compromising safety.     

The interface between medical anthropology and medical ethnobiology

Medical anthropology is concerned with both the causes and consequences of human sickness, and its various theoretical orientations can be grouped into four major approaches: medical ecology, critical medical anthropology, interpretative medical anthropology, and ethnomedicine. While medical anthropologists of all theoretical persuasions have examined why people get sick, the analysis and understanding of patterns of treatment has been largely confined to ethnomedicine. Historically, more emphasis has been placed on the personalistic or supernatural aspects of ethnomedical systems than on naturalistic or empirical components. While this focus has produced valuable insights into the role of ritual and belief in healing, it has led to the impression that traditional medicine is primarily symbolic. Moreover, it ignores the theoretical bases of traditional healing strategies and the practical means by which most of the world heals itself, namely plants. Recently there has been more interest in the empirical character of ethnomedical systems, and in this paper we consider the role that medical ethnobiology has played in this shift of focus. We begin with a brief history of medical anthropology to illuminate why naturalistic medicine was neglected for so long. We then review exemplary research in two areas of medical ethnobiology – ethnophysiology and medical ethnobotany – that address the study of naturalistic aspects of medical systems. We conclude with suggestions for future research at the interface between medical ethnobiology and medical anthropology that will contribute to both fields.     

Comparison of medical care in prison and in general practice.

The medical care of prisoners "declaring sick" to the medical officer and hospital officers in Bedford Prison was surveyed and compared with the medical care given to the medical officer''s patients in general practice. The consultation rate of prisoners was higher than that of patients in the practice. Part of this increase was because household remedies were not available to prisoners except through the prison medical service and part may also have been due to the stresses of life in prison. Few psychoactive drugs were prescribed in prison. The problems that prisoners presented reflected the problems of violence and poor hygiene in prison. Some problems that more commonly present in prison than in general practice may be related to stress.     

The Oslerian Tradition and Changing Medical Education: A Reappraisal

Although only 21 of Sir William Osler''s 45 years in academic medicine were spent in US medical schools (1884 to 1905), he played a major role in shaping modern medical education in this country. The integration of scholarship with patient care, together with the science and art of medicine, was central to Osler''s teaching and writing throughout his career. A classic generalist and a charismatic clinical teacher, he taught by example and was as concerned with the ideals of medicine as with its science and knowledge.Many changes have reshaped the content, process and concerns of American medical education since Osler''s time. Subspecialization and balkanization of medical education and practice have become dominant. Many of the important issues in medicine today do not fit neatly into the domain of any of the established specialties or medical organizations. There is now an urgent need to promote generalist attitudes in medicine, and the Oslerian tradition has much to offer in approaching today''s problems in medical education and practice.     

Canadian Medical Student Interest in General Practice and the Specialties

The interest of 1900 Canadian medical students in the various fields of medical practice was measured by a questionnaire. The students were asked to rank the various fields in order of their interest in them. It was found that general practice, internal medicine and surgery were the fields which consistently captured most interest among the students. Few students ranked dermatology, administration, teaching and research in the first three ranks.Striking differences in the interest preferences of male and female students were demonstrated, with the women ranking pediatrics and psychiatry higher than the men. Significantly more men, however, expressed a prime interest in surgery.Interest in general practice increases with the senior years in medical school, but it was shown that this increase is associated with marital status and with the number of children rather than with the year of training alone.Interest in the fields of medical practice varied between medical schools, with general practice ranking highest at British Columbia and relatively low at McGill and Manitoba. Significant differences between the students of the schools were displayed in the case of neurology, obstetrics, pediatrics and psychiatry.
