Bioinformatics pipeline for the systematic mining genomic and proteomic variation linked to rare diseases: The example of monogenic diabetes.

Monogenic diabetes is characterized as a group of diseases caused by rare variants in single genes. Like for other rare diseases, multiple genes have been linked to monogenic diabetes with different measures of pathogenicity, but the information on the genes and variants is not unified among different resources, making it challenging to process them informatically. We have developed an automated pipeline for collecting and harmonizing data on genetic variants linked to monogenic diabetes. Furthermore, we have translated variant genetic sequences into protein sequences accounting for all protein isoforms and their variants. This allows researchers to consolidate information on variant genes and proteins linked to monogenic diabetes and facilitates their study using proteomics or structural biology. Our open and flexible implementation using Jupyter notebooks enables tailoring and modifying the pipeline and its application to other rare diseases.

[VDT worker's posture and workload in free-address office system].

A free-address system is a new office layout in which a worker can freely sit in their favorite place with a computer and materials. Since this layout has recently been introduced in offices, we conducted a questionnaire survey which aimed to clarify the effects of the free-address system on visual display terminals (VDT) workers' posture and workload. A total of 203 male VDT workers who were system engineers aged 20 to 59 using a notebook computer were evaluated, of whom 150 used the free-address layout, and 53 used the fixed-address layout. The free-address layout was effective in the improvement of individual work space compared with the fixed-address layout. Also, in this layout the worker did not feel dissatisfaction with communication or support between workers. However, workers using the free-address layout assumed an unsuitable work posture, without adjusting the height of their chairs. Furthermore, this layout might have risk factors which increase neck/shoulder and low back stiffness and/or pain. Therefore, the free-address layout may have incipient problems, and it will be necessary to examine further the effects of this layout on VDT worker's health.

[Understanding the theoretical bases of participative planning in the integrated curriculum of a nursing course].

This paper deals with an exploratory study aimed at identifying the theoretical bases that sustain participative planning as described in the framework of Situational Strategic Planning, which are used in the integrated curriculum of undergraduate nursing education for the development of participative planning performance. Data were obtained through documentary analysis of twenty-two notebooks of the Educational Units that are part of the Marília Medical School Nursing Course curriculum, with a view to recognizing those parts of knowledge that contributed to the formation of the social actor, situation and social production concepts. Result analysis recognized the lack of theoretical bases, as well as the predominance of knowledge aims and the description of performance as objectives. However, attempts were revealed to integrate knowledge and approximate them to participative planning, with a view to achieving coherence with the principles of the integrated curriculum.

[Evidence-based clinical practice. Part II--Searching evidence databases].

The inadequacy of most of traditional sources for medical information, like textbook and review article, do not sustained the clinical decision based on the best evidence current available, exposing the patient to a unnecessary risk. Although not integrated around clinical problem areas in the convenient way of textbooks, current best evidence from specific studies of clinical problems can be found in an increasing number of Internet and electronic databases. The sources that have already undergone rigorous critical appraisal are classified as secondary information sources, others that provide access to original article or abstract, as primary information source, where the quality assessment of the article rely on the clinician oneself . The most useful primary information source are SciELO, the online collection of Brazilian scientific journals, and Medline, the most comprehensive database of the USA National Library of Medicine, where the search may start with use of keywords, that were obtained at the structured answer construction (P.I.C.O.), with the addition of boolean operators "AND", "OR", "NOT". Between the secondary information sources, some of them provide critically appraised articles, like ACP Journal Club, Evidence Based Medicine and InfoPOEMs, others provide evidences organized as online texts, such as "Clinical Evidence" and "UpToDate", and finally, Cochrane Library are composed by systematic reviews of randomized controlled trials. To get studies that could answer the clinical question is part of a mindful practice, that is, becoming quicker and quicker and dynamic with the use of PDAs, Palmtops and Notebooks.

Association between birth weight and serum lipid concentration in premenopausal Japanese women.

BACKGROUND: The relationships between birth weight and serum lipid concentrations in pre-menopausal Japanese women were not well identified and also diet and serum hormone status in these women would be considered. METHODS: A total of 59 premenopausal Japanese women completed a self-administered questionnaire including basic demographic information, disease histories, and menstrual and reproductive histories. They were asked to obtain information on birth weight recorded in mother-and-baby notebook issued by municipality from their mother. Diet was assessed by daily diet records from day 2 through day 10 of the menstrual cycle. Blood sample was collected on day 11 of the cycle to measure serum lipid and hormone concentrations (total and high-density lipoprotein [HDL] cholesterols, triglyceride, estrone, estradiol, and sex hormone-binding globulin). RESULTS: Birth weight was significantly correlated with HDL cholesterol (r = 0.32, p = 0.03), but not with total cholesterol and triglyceride after controlling for age. Neither estrogen nor sex hormone-binding globulin was significantly correlated with serum lipid concentrations after controlling for age and the number of days prior to the next menses. The correlation between birth weight and HDL cholesterol was not affected after additional adjustment for serum estrogen and intakes of protein, calcium, and iron. CONCLUSION: These data suggest that intrauterine growth may be associated with lipid profile.

Web-based care management in patients with poorly controlled diabetes.

OBJECTIVE: To assess the effects of web-based care management on glucose and blood pressure control over 12 months in patients with poorly controlled diabetes. RESEARCH DESIGN AND METHODS: For this study, 104 patients with diabetes and HbA(1c) (A1C) > or =9.0% who received their care at a Department of Veterans Affairs medical center were recruited. All participants completed a diabetes education class and were randomized to continue with their usual care (n = 52) or receive web-based care management (n = 52). The web-based group received a notebook computer, glucose and blood pressure monitoring devices, and access to a care management website. The website provided educational modules, accepted uploads from monitoring devices, and had an internal messaging system for patients to communicate with the care manager. RESULTS: Participants receiving web-based care management had lower A1C over 12 months (P < 0.05) when compared with education and usual care. Persistent website users had greater improvement in A1C when compared with intermittent users (-1.9 vs. -1.2%; P = 0.051) or education and usual care (-1.4%; P < 0.05). A larger number of website data uploads was associated with a larger decline in A1C (highest tertile -2.1%, lowest tertile -1.0%; P < 0.02). Hypertensive participants in the web-based group had a greater reduction in systolic blood pressure (P < 0.01). HDL cholesterol rose and triglycerides fell in the web-based group (P < 0.05). CONCLUSIONS: Web-based care management may be a useful adjunct in the care of patients with poorly controlled diabetes.

Personal computer programs to assist with self-monitoring of blood glucose and self-adjustment of insulin dosage.

We have developed computer programs in compiled BASIC for the IBM-PC and compatible microcomputers for use by physicians, paramedical personnel, and/or patients to assist with self-monitoring of blood glucose (SMBG) and self-adjustment of insulin dosage. The programs can potentially assist with patient education and motivation, and provide: a customized "electronic notebook" for storage and retrieval of information on blood glucose, insulin dosage, hypoglycemic reactions, urinary ketones, diet, activity, weight, illness, apparent explanations for hypoglycemic reactions or glucose values outside target ranges, and comments; graphic displays of glucose and insulin versus date, and of a "glucose profile" versus time of day or versus day of the week; simple and detailed statistical analyses; a legible summary of data; a facility to permit the physician to prepare a "customized treatment plan" for each patient, involving a choice of six regimens, target levels for each of eight time periods, four supplement tables (when well or sick, before meals, or at bedtime), rules to reduce insulin in response to hypoglycemic reactions or documented hypoglycemia, rules to increase routine insulin doses in response to persistent unexplained hyperglycemia, and rules when the patient should call the physician; suggestions regarding compensatory supplements and adjustments of routine insulin dosage; explanations why various insulin dosages should or should not be altered, and why various glucose values should be tested; comparisons of the insulin dosage administered by the patient and the recommendations of the program, together with explanations for discrepancies offered by the patient, to help evaluate compliance. The program is "user-friendly," easy to learn, and easy to use.(ABSTRACT TRUNCATED AT 250 WORDS)

Ergonomic comparison of operating a built-in touch-pad pointing device and a trackball mouse on posture and muscle activity.

This study examined the effects of operating a built-in touch-pad pointing device and a trackball mouse on participants' completion times, hand positions during operation, postural angles, and muscle activities. 8 young men were asked to perform a cursor travel task on a notebook computer using both 60- and 80-cm high table conditions. Analysis showed that the trackball mouse significantly decreased completion times. Participants selected a hand position farther from the table edge and larger elbow angle for the trackball mouse than for the built-in touch-pad pointing device. Participants' neck, thoracic, and arm angles, or splenius capitis, trapezius, deltoid, and erector spinae muscle activities were not significantly affected by the devices, but table height significantly affected participants' completion times, hand positions, and postural angles.

Ergonomic evaluation of working posture of VDT operation using personal computer with flat panel display.

The aim of this study was to evaluate working conditions using a personal computer with a flat panel display (FPD) in terms of visual and musculoskeletal comfort. Measurements of viewing distance, viewing angle, head angle, neck angle and electromyogram (EMG) activities of the neck, shoulder and back muscles of visual display terminal (VDT) operators were compared at workstations using an FPD and a desktop personal computer (DPC). A notebook personal computer (NPC) with a 10.4 inches FPD, was used in this experiment. Each of 10 healthy subjects performed word processing tasks using both NPC and DPC workstations. Significant differences in the work posture while using the NPC and DPC were seen with viewing distance, viewing angle and head angle. The characteristic features of the work posture using the NPC were a remarkably short viewing distance and a forward inclination of the head. The value of integrated EMG (IEMG) of the neck muscle was greater while using the NPC than when using the DPC. These phenomena were caused by the structure of NPCs; most NPCs have a display and keyboard which cannot be separated and are not adjustable without tilt and swivel mechanisms. VDT devices that cannot be adjusted may potentially make operators assume a poor posture while working, which could cause visual and musculoskeletal disorders. To prevent visual and musculoskeletal problems using NPCs, a more upright head and neck position was recommended. The addition of a mechanism for adjustment of the height of an NPC display would allow a comfortable downward gaze without the loss of correct posture.

Implications of practice parameters (guidelines).

Practice parameters (guidelines) have been developed for many years. The first such parameter, developed by a Joint Task Force of the American Academy of Allergy and Immunology, and the American College of Allergy and Immunology, was on the diagnosis and treatment of patients with asthma. It was sent in notebook form to members of the Academy and College in 1993. An updated version will be published as a supplement to the Journal of Allergy and Clinical Immunology sometime in 1995. Although the overriding consideration in the development of these parameters is to improve the level of care for patients, and by doing so to decrease asthma morbidity and mortality, recent guidelines have also emphasized cost factors, especially those that are now being developed by managed care organizations. Practice parameters can also reduce malpractice liability, and studies have even shown a reduction in hospital admissions by instituting relatively simple measures of patient behavior. There is no doubt that practice parameters will become an important part of our everyday life.

Team approach to teaching participatory group process involving natural resources and agriculture.

Contemporary issues are defined by people who share diverse and often strongly defended views about the topic. In Oregon, citizens are increasingly being asked or expected to participate in complex decisions that require a consensus. Rather than teach one professor's synthesis of a contemporary natural resource issue, faculty from six disciplines coach group process, interactive learning skills, and systems thinking as a way to address complex issues from multiple perspectives. Students learn by grappling with a natural resource issue of their choice within groups based on a diversity among majors, degree status, and gender. Students define situation (S), brainstorm new or different targets (T), and analyze two or more pathways (P), using an STP learning and action process. Exploring potential pathways involves defining possible consequences, stakeholder views, feasibility (ecological, social, economic, and political), and planning that includes expected behavior of the improved system over time. Students present their topics and improvements showing systemic relationships, systematic analysis, and integration of scientific facts and secondary data at midterm and during finals. Reflective learning is fostered throughout the course with prompted questions in a journal notebook. Grading criteria promote meaningful inquiry and participation in group process combined with integration of scientific facts and reflective learning.

Diagnostic airway pressure recording in sleep apnea syndrome.

A comparison was made between polysomnographic recordings and recordings of airflow pressures in the pharynx and respiratory pressures in the esophagus of 10 adult sleeping subjects with differing degrees of apnea. Pressure measurements were obtained by microsensors mounted on a 7F gauge flexible catheter which sited them in the epi-, meso- and hypopharynx and the esophagus. Digitized overnight pressure data were stored on a PC memory card and subsequently displayed for analysis by means of a notebook computer. In 2 patients examination of 200 obstructive, mixed and central apneic events showed no significant differences in recordings of their incidence, duration of classification between polysomnographic and either pharyngeal or esophageal pressure techniques. Onset of apnea was demonstrated with particular clarity by computer integration of the pressure tracings. The multiple pressure sensor method offered a further important advantage in detecting the caudal limits of pharyngeal obstructions by steep elevation of the pressure gradient in the pharyngeal segment between adjacent sensors in which the caudal limit of the obstruction was sited. The multiple pressure sensor technique provided reliable and comprehensive diagnostic information of breathing disorders in sleeping subjects and together with its miniaturized recording equipment the method commends itself as suitable for home monitoring.

Drawing to communicate: a case report of an adult with global aphasia.

Treatment for adults with global aphasia has typically involved the use of verbal treatment methods or alternative communication techniques including communication boards, word lists and notebooks. However, many adults with aphasia are unable to communicate verbally and alternative communication techniques can be limited, as a result of the restricted number and type of concepts that can be adequately depicted and expressed. Another viable means of communication for the globally aphasic adult is drawing. However, few individuals with severe aphasia initiate communication through this modality without specific training. In this case report we present several successful treatment methods that were used to train an adult with global aphasia to communicate more effectively through drawing. Several of his drawings are presented to illustrate the results of training in the use of drawing as an alternative means of communication.

Prospective study of methodological issues in intracranial pressure monitoring in patients with hydrocephalus.

OBJECT: Continuous intracranial pressure (ICP) monitoring is performed in selected patients with hydrocephalus to determine whether shunt placement is required. The mean ICP is usually calculated from end-hour readings manually recorded by nurses. The aim of this study was to evaluate the accuracy of manual recordings by comparing nurses' end-hour ICP readings with those of an online computerized ICP monitoring system that records one ICP value per second. METHODS: Continuous ICP monitoring was performed using a fiberoptic extradural sensor in 115 patients with hydrocephalus of different origins. A notebook computer was connected to an ICP monitor and was programmed to register one ICP value per second. In all patients, mean ICP values were calculated from data recorded manually by nurses at the end of every hour and from data recorded by the computer within the preselected time period. The two methods were compared using correlation analysis and the Bland and Altman method. The median number of ICP values noted manually by the nurses in each patient was 17 (interquartile range 15-18 readings), and that recorded by the software was 61,200 (interquartile range 54,000-64,800 readings). The correlation coefficient of the mean ICP values recorded by both methods was r = 0.99 (p < 0.001). The Bland and Altman analysis revealed a mean difference of 0.3 +/- 1.26 mm Hg between the two methods and that they were equally valid with all mean ICP values. CONCLUSIONS: The recording of end-hour ICP values by nurses is an accurate method of calculating the mean ICP after prolonged ICP monitoring in patients with hydrocephalus.

Automated Portable Test (APT) System: overview and prospects.

The Automated Portable Test (APT) System is a notebook-sized, computer-based, human-performance and subjective-status assessment system. It is now being used in a wide range of environmental studies (e.g., simulator aftereffects, flight tests, drug effects, and hypoxia). Three questionnaires and 15 performance tests have been implemented, and the adaptation of 30 more tests is underway or is planned. The APT System is easily transportable, is inexpensive, and has the breadth of expansion options required for field and laboratory applications. The APT System is a powerful and expandable tool for human assessment in remote and unusual environments.

The child with multiple congenital anomalies.

Specific ways to improve the delivery of comprehensive care to a family whose child has multiple congenital anomalies include the following: 1. Develop a diagnostic plan which establishes medical, psychosocial, and developmental priorities at different ages. 2. Keep lists in the front of the chart which allow easy reference regarding problems, procedures, and resources. 3. Establish communication with designated community and educational coordinators, discussing who will be rendering which services. 4. Ask the parents to keep a notebook which will serve as a repository for notes and communication, accessible to all people caring for the child. Though some of these ideas require extra time at the beginning, the time saved later can be significant.

What clinical information resources are available in family physicians' offices?

BACKGROUND: When faced with questions about patient care, family physicians usually turn to books in their personal libraries for the answers. The resources in these libraries have not been adequately characterized. METHODS: We recorded the titles of all medical books in the personal libraries of 103 randomly selected family physicians in eastern Iowa. We also noted all clinical information that was posted on walls, bulletin boards, refrigerators, and so forth. Participants were asked to describe their use of other resources such as computers, MEDLINE, reprint files, and "peripheral brains" (personal notebooks of clinical information). For each physician, we recorded how often the resources were used to answer clinical questions during 2 half-day observation periods. RESULTS: The 103 participants owned a total of 5794 medical books, with 2836 different titles. Each physician kept an average of 56 books in the office. Prescribing references (especially the Physicians' Desk Reference) were most common (owned by 100% of the participants), followed by books on general internal medicine (99%), adult infectious disease (89%), and general pediatrics (83%). Books used to answer clinical questions were more likely to be up to date (copyright date within 5 years) than unused books (74% vs 27%, P <.001). Items posted on walls included drug dosage charts and pediatric immunization schedules. Only 26% of the physicians had computers in their offices. CONCLUSIONS: Drug-prescribing textbooks were the most common type of book in family physicians' offices, followed by books on general internal medicine and adult infectious diseases. Although many books were relatively old, those used to answer clinical questions were generally current.

Contemporary issues in HIM. The application layer--III.

We have seen document preparation systems evolve from basic line editors through powerful, sophisticated desktop publishing programs. This component of the application layer is probably one of the most used, and most readily identifiable. Ask grade school children nowadays, and many will tell you that they have written a paper on a computer. Next month will be a "fun" tour through a number of other application programs we find useful. They will range from a simple notebook reminder to a sophisticated photograph processor. Application layer: Software targeted for the end user, focusing on a specific application area, and typically residing in the computer system as distinct components on top of the OS. Desktop publishing: A document preparation program that begins with the text features of a word processor, then adds the ability for a user to incorporate outputs from a variety of graphic programs, spreadsheets, and other applications. Line editor: A document preparation program that manipulates text in a file on the basis of numbered lines. Word processor: A document preparation program that can, among other things, reformat sections of documents, move and replace blocks of text, use multiple character fonts, automatically create a table of contents and index, create complex tables, and combine text and graphics.
