RESUMEN
Low birth weight (LBW) can cause lifelong impairments in muscle development and growth. Satellite cells (SC) and their progeny are crucial contributors to myogenic processes. This study provides new data on LBW in piglets combining insights on energy metabolism, muscle capillarization and differences in SC presence and function. To this aim, muscle tissues as well as isolated myogenic cells of 4-day-old German Landrace piglets were analyzed. For the first time two heterogeneous SC subpopulations, which contribute differently to muscle development, were isolated from LBW pigs by Percoll density gradient centrifugation. The muscles of LBW piglets showed a reduced DNA, RNA, and protein content as well as lower activity of the muscle specific enzymes CK, ICDH, and LDH compared to their normal birth weight siblings. We assume that deficits in energy metabolism and capillarization are associated with reduced bioavailability of SC, possibly leading to early exhaustion of the SC reserve cell pool and the cells' premature differentiation.

BACKGROUND: Measurements of plasma free metanephrines provide a sensitive test for the diagnosis of pheochromocytoma/paraganglioma (P/PGL), with highly elevated levels diagnostic of the disease. However, there is less diagnostic certainty in patients with mild elevations of these catecholamine metabolites. PATIENTS AND METHODS: Here we report use of the clonidine suppression test (CST) as a second-tier diagnostic test in 24 patients with mild elevations of plasma free metanephrines and/or catecholamines. Blood samples before and 3 hours after clonidine were analyzed for plasma concentrations of metanephrines and catecholamines with a negative test result defined as either a clonidine-induced fall in normetanephrine or noradrenaline by more than 40â% and 50â% respectively or to below the upper cut-offs of reference intervals. RESULTS: P/PGLs were confirmed in 9 patients and excluded in 15 by independent criteria. More than half of the patients without P/PGL showed normalized plasma concentrations of normetanephrine at baseline before clonidine compared to initial screening; all showed appropriate clonidine-induced falls in normetanephrine and noradrenaline or levels after the drug below upper cut-offs, indicating a diagnostic specificity of 100â% (CI 78-100â%). However, similar responses for noradrenaline were noted in 7 patients with P/PGL, indicating a diagnostic sensitivity of only 22â% (CI 2,8-60â%) compared to 100â% (CI 66-100â%) for normetanephrine. CONCLUSION: These results support use of the CST in combination with measurements of normetanephrine for confirming or excluding P/PGL in patients with borderline elevated test results, which should, however, first be confirmed by sampling blood under standardized resting conditions.

OBJECTIVE: Recommendations to use integrated models for health behavior change abound, however, the translation to practice has been poor. We used stimulated reflections of primary care physicians and nurse practitioners to generate insights about current practices and opportunities for changing how health behavior advice is addressed. METHOD: Twenty-one community practicing primary care clinicians invited to a nationally sponsored practice-based research network conference on promotion of healthy behaviors were asked to record aspects of health behaviors they addressed during a day of outpatient visits. In response to eight questions, clinicians reflected insights which were then analyzed by a multidisciplinary team to identify over-arching themes. RESULTS: Health behavior discussions are initiated and carried out predominantly by the clinician. These discussions occur primarily during health care maintenance visits or visits in which presenting complaints or chronic illnesses can be linked to health behaviors. Clinicians' reflections on viable opportunities for change include different modes of patient education materials such as web-based materials. Suprisingly infrequent were solutions outside of the clinical encounter or strategies that engage other staff or other community partners. CONCLUSION: Implementation of the integrated care model as an opportunity to enhance health promotion seems far from the current realities and future vision of even motivated network-based clinicians.

BACKGROUND: It is common today to use tumescent anaesthesia with large doses of lidocaine for liposuction. The purpose of the present study was to evaluate lidocaine plasma levels and objective and subjective symptoms during 20 h after tumescent anaesthesia with approximately 35 mg per kg bodyweight of lidocaine for abdominal liposuction. METHODS: Three litres of buffered solution of 0.08% lidocaine with epinephrine was infiltrated subcutaneously over the abdomen in eight female patients during monitored intravenous (i.v.) light sedation. Plasma levels of lidocaine and signs of subjective and objective symptoms were recorded every 3 h for 20 h after liposuction. RESULTS: Lidocaine 33.2 +/- 1.8 mg/kg was given at a rate of 116 +/- 11 ml/min. Peak plasma levels (2.3 +/- 0.63 microg/ml) of lidocaine occurred after 5-17 h. No correlation was found between peak levels and dose per kg bodyweight or total amount of lidocaine infiltrated. One patient experienced tinnitus after 14 h when a plasma level of 3.3 microg/ml was recorded. CONCLUSION: Doses of lidocaine up to 35 mg/kg were sufficient for abdominal liposuction using the tumescent technique and gave no fluid overload or toxic symptoms in eight patients, but with this dose there is still a risk of subjective symptoms in association with the peak level of lidocaine that may appear after discharge.

BACKGROUND: During endoscopic transthoracic sympathicotomy (ETS) in patients with hyperhidrosis it is useful to assess the effect of surgery peroperatively. However, the autonomic system is affected in various ways by different anesthetic agents. In the present study, the effect of ETS during either isoflurane or propofol anesthesia was evaluated by measuring changes in the finger pulp microcirculation using laser Doppler flowmetry (LDF). Electric stimulation of the sympathetic chain was used for identifying the sympathetic chain and to explore whether the anesthetic agents differentially influenced the LDF response to stimulation. METHODS: From a group of 12 patients with incapacitating palmar hyperhidrosis, six were randomly assigned to isoflurane and six to propofol anesthesia. LDF probes were attached to the ipsilateral finger pulp for continuous recording of peripheral blood flow during the ETS procedure. Electric stimulation (1 Hz, 10 Hz, and 100 Hz) was applied to the sympathetic paravertebral chain at the levels of the 2nd and 3rd sympathetic ganglia via a custom designed bipolar electrode. In eight of the patients LDF recordings were also performed in the awake state and compared with records obtained from eight healthy subjects. FINDINGS: In patients anesthetized with isoflurane, the base line finger pulp blood flow did not significantly differ from that of awake normal subjects, while those anesthetized with propofol had a lower base line flow, similar to that of awake subjects with hyperhidrosis. Stimulation of the sympathetic chain induced marked reduction of finger pulp microcirculation in both anesthetic groups, and this effect was frequency dependent during isoflurane anesthesia. After ETS a significant increase in flow was recorded only in the propofol group. Interpretation. The study demonstrates that the completeness of the sympathicotomy can only be peroperatively evaluated if an anesthetic agent with relatively low vasodilatory capacity, as e.g. propofol, is utilized.

Racial disparities in the process and outcome of health care may be partially explained by differences in time use during outpatient visits by African-American and white patients. This study was undertaken to determine whether physicians use their time in clinical encounters with African-American patients differently than with white patients. This study was a multimethod, cross-sectional study conducted between October 1994 and August 1995 in 84 family practices in northeast Ohio. Participants were 4,352 white and African-American outpatients visiting 138 physicians. Time use during the patient visit was measured by the Davis Observation Code, which categorizes every 20-second interval into 20 different behavioral categories. Among 3,743 white and 509 African-American patients, after adjustment for potential confounders, visits by African-American patients were slightly longer than visits with white patients (10.7 vs. 10.1 minutes, p = 0.027). After further adjustment for multiple comparisons, physicians spent a lower proportion of time intervals with African-American patients as compared to white patients planning treatment (29.0% vs. 32.1%, p < 0.001), providing health education (16.4% vs. 19.7%, p < 0.001), chatting (5.2% vs. 7.6%, p < 0.001), assessing patients' health knowledge (0.8% vs. 1.2%, p < 0.001), and answering questions (5.8% vs. 6.9%, p = 0.002). Physicians spent relatively more time intervals with African-American patients discussing what is to be accomplished (9.3% vs. 7.6%, p < 0.001) and providing substance use assessment and advice (0.8% vs. 0.4%, p = 0.001). In conclusion, physicians spend time differently with African-American as compared with white patients. These differences may represent appropriate tailoring of services to meet unique needs, but could also represent racial bias.

BACKGROUND: Health behavior advice can potentially prevent a large burden of illness, but the acceptability of this advice to patients is not well understood. This study assessed whether physician discussion of behavioral risk factors decreases patient satisfaction with the outpatient visit. METHODS: In a cross-sectional study of 2,459 consecutive adult outpatient visits to 138 community family physicians in Northeast Ohio, the association of health habit counseling, measured by direct observation, with patient satisfaction, assessed by a modified subscale of the MOS 9-item visit rating scale, was calculated by logistic regression. RESULTS: In analyses controlling for patient mix, discussion of diet, exercise, alcohol and other substance use, sexually transmitted disease, and HIV prevention was not associated with patient satisfaction. Patients who were asked about their tobacco use or counseled about quitting were more likely to be very satisfied with the physician. CONCLUSIONS: Discussion of health behavior change, as practiced by community family physicians, is not associated with diminished patient satisfaction. In fact, tobacco use assessment and cessation counseling are associated with greater satisfaction.

BACKGROUND: Our objective was to understand family practices from the ground up through intensive direct observation of the practice environment and patient care. METHODS: Eighteen practices were purposefully drawn from a random sample of Nebraska family practices that had earlier participated in a study of preventive service delivery. Each practice was studied intensely over a 4- to 12-week period using a comparative case study design that included extended direct observation of the practice environment and clinical encounters, formal and informal interviews of clinicians and staff, and medical record review. DESIGN: This multimethod assessment process (MAP) provided insights into a wide range of practice activities ranging from descriptions of the organization and patient care activities to quantitative documentation of physician- and practice-level delivery of a wide range of evidence-based preventive services. Initial insights guided subsequent data collection and analysis and led to the integration of complexity science concepts into the design. In response to the needs and wishes of the participants, practice meetings were initiated to provide feedback, resulting in a more collaborative model of practice-based research. CONCLUSIONS: Our multimethod assessment process provided rich data for describing multiple aspects of primary care practice, testing a priori hypotheses, discovering new insights grounded in the actual experience of practice participants, and fostering collaborative practice change.

BACKGROUND: Numerous studies have documented racial disparities in delivery of health care treatment services, but there is little information to determine whether similar disparities exist in the delivery of preventive services. OBJECTIVE: To determine if disparities exist in preventive service delivery to non-Hispanic white patients and black patients in primary care. RESEARCH DESIGN: Multimethod study using direct observation of patient encounters, medical record review, and patient exit questionnaire. SUBJECTS: Four thousand three hundred thirteen outpatients presenting to 138 family physicians. MEASURES: Delivery of 15 screening, 24 health-habit counseling and 11 immunization services recommended by the US Preventive Services Task Force. RESULTS: Using multilevel linear regression analysis, no significant racial differences were found in rates of delivery of screening services or immunizations. However, black patients were more likely to receive preventive health-habit counseling (mean percent of patients up-to-date on all recommended counseling services, adjusted for covariates: 11.6% for black patients, 9.5% for whites, P = 0.003). CONCLUSIONS: Black patients able to access primary care receive preventive services at rates equal to or greater than white patients. This suggests that efforts to increase delivery of preventive care in black patients need to focus on access to primary care.

BACKGROUND: Although data are available on rates of delivery of preventive services by primary care physicians, the proportion of services delivered because of related symptoms or signs, rather than for primary or secondary prevention of disease is not known. METHODS: Research nurses directly observed 4454 consecutive visits to 138 practicing family physicians. Direct observation was used to identify delivery of 36 different services recommended by the U.S. Preventive Services Task Force and to assess whether delivery of these services was associated with related signs or symptoms. RESULTS: One or more preventive services were delivered in 33% of visits, with rates ranging from 0.2% (HIV prevention) to 19.9% (tobacco counseling). In contrast to pure prevention, services were frequently performed for assessment or care of symptoms or signs, with the ratio ranging from 0% (eye examination; car seat, poison control, and HIV prevention counseling) to 66.7% (hearing test). Physicians varied considerably in the frequency at which their delivery of recommended preventive services was associated with patient symptoms, from 0% to 100% for screening services and from 0% to 100% for counseling services. CONCLUSIONS: Because of the illness focus of most primary care visits, preventive service delivery is often associated with related signs or symptoms. Care of illnesses appears to present an important impetus and perhaps teachable moments for providing preventive care. Clinician variability in preventive service delivery for patient symptoms shows an opportunity to improve the primary and secondary prevention focus of practice to meet public health prevention goals.

The Case Western Reserve University (CWRU) School of Dentistry has organized a research network of 210 general dentists in northern Ohio. Seventeen of these dentists have volunteered to serve on a steering committee, for the purpose of generating research questions and helping with network organization. To enable the practitioners to investigate questions of interest in their practices, faculty in the CWRU schools of Dentistry and Medicine provide consultation to network dentists, as needed, with regard to research design, implementation, and analysis. In turn, the network serves as a resource for the dental school, facilitating faculty development, encouraging the development of new research programs, and providing an opportunity for students throughout the university to become involved in dental practice research. To date, faculty members have initiated studies of dental practice that include a survey of dentists' attitudes toward tobacco, a weekly return caries study, and a direct observation study of general dental practice. The network provides a research "laboratory" for the dental school, enabling clinical faculty to participate in research concerning dental practice. It has also stimulated a major re-examination of several curriculum elements in the school.

OBJECTIVE: Poor quality of diabetes care has been ascribed to the acute care focus of primary care practice. A better understanding of how time is spent during outpatient visits for diabetes compared with visits for acute conditions and other chronic diseases may facilitate the design of programs to enhance diabetes care. RESEARCH DESIGN AND METHODS: Research nurses directly observed consecutive outpatient visits during two separate days in 138 community family physician offices. Time use was categorized into 20 different behaviors using the Davis Observation Code (DOC). Time use was compared for visits for diabetes, other chronic conditions, and acute illnesses during 1,867 visits by patients > or =40 years of age. RESULTS: Of 20 DOC behavioral categories, 10 exhibited differences among the three groups. Discriminant analysis identified two distinct factors that distinguished visits for chronic disease from visits for acute illness and visits for diabetes from those for other chronic diseases. Compared with visits for other chronic diseases, visits for diabetes devoted a greater proportion of time to nutrition counseling, health education, and feedback on results and less time to chatting. Compared with visits for acute illness, visits for diabetes were longer and involved a higher proportion of dietary advice, negotiation, and assessment of compliance. CONCLUSIONS: Visits for diabetes are distinct from visits for other chronic diseases and acute illnesses in ways that may facilitate patient self-management. Novel quality-improvement interventions could support and expand existing differences between family physicians' current approaches to care of diabetes and other chronic and acute illnesses.

BACKGROUND: The potential of primary care practice settings to prevent disease and morbidity through health habit counseling, screening for asymptomatic disease, and immunizations has been incompletely met. This study was designed to test a practice-tailored approach to increasing preventive service delivery with particular emphasis on health habit counseling. DESIGN: Group randomized clinical trial and multimethod process assessment. SETTING/PARTICIPANTS: Seventy-seven community family practices in northeast Ohio. INTERVENTION: After a 1-day practice assessment, a nurse facilitator met with practice clinicians and staff and assisted them with choosing and implementing individualized tools and approaches aimed at increasing preventive service delivery. MAIN OUTCOME MEASURE: Summary scores of the health habit counseling, screening and immunization services recommended by the U.S. Preventive Services Task Force up to date for consecutive patients during randomly selected chart review days. RESULTS: A significant increase (p=0.015) in global preventive service delivery rates at the 1-year follow-up was found in the intervention group (31% to 42%) compared to the control group (35% to 37%). Rates specifically for health habit counseling (p=0.007) and screening services (p=0.048) were increased, but not for immunizations. CONCLUSIONS: An approach to increasing preventive service delivery that is individualized to meet particular practice needs can increase global preventive service delivery rates.

Myocarditis, pericarditis and pleural effusion as secondary immunological reactions due to meningococcal meningitis are rare. Meningococcal meningitis is itself uncommon, with a morbidity of approximately 1.25 cases per 100,000 inhabitants per year in Germany. Cardial participation could be observed either primary infectious-toxic in the first week or secondary immunologic in the second week after disease onset. In our patient, six days after the onset of meningococcal meningitis (serogroup B) a distinct swelling of the myocardium appeared together with pericardial effusion in the absence of Waterhouse-Friderichsen syndrome. This case is proving difficult to tackle therapeutically due to repeated relapses.

Borrowed and adapted knowledge is insufficient to optimize the potential of a comprehensive, integrative, relationship-centered generalist approach to improve the health of individuals, families, and communities. The knowledge base for family practice must be expanded by integrating multiple ways of knowing. This involves (1) self-reflective practice by clinicians, (2) involving the patient voice in generating research questions and interpreting data, (3) inquiry into the systems affecting health care, and (4) investigation of disease phenomena and treatment effects in patients over time. A multimethod, transdisciplinary, participatory approach is needed to create knowledge that retains connections with its meaning and context and therefore is readily translated into practice. This research integrates quantitative and qualitative traditions and involves the active participation of both clinicians and patients. The generation of relevant knowledge should be supported through (a) developing a culture of reflective practice among clinicians, (b) expanding the infrastructure for practice-based research, (c) developing a multimethod, transdisciplinary, participatory research paradigm, (d) longitudinal study of the process and outcomes of broad, integrative, relationship-centered care, and (e) incorporating pursuit of new knowledge as a central feature of training programs and policy. The time has come for the generalist disciplines to commit to the generation of new knowledge based on the needs of patients, families, and communities for relationship-centered, integrated, prioritized health care. Development of a culture of learning and inquiry, and the necessary research methods and skills will require a long-term commitment, creation of partnerships, and a focus on core principles by individuals and organizations.

BACKGROUND: Care of a secondary patient (an individual other than the primary patient for an outpatient visit) is common in family practice, but the content of care of this type of patient has not been described. METHODS: In a cross-sectional study, 170 volunteer primary care clinicians in 50 practices in the Ambulatory Sentinel Practice Network reported all occurrences of care of a secondary patient during 1 week of practice. These clinicians reported the characteristics of the primary patient and the secondary patient and the content of care provided to the secondary patient. Content of care was placed in 6 categories (advice, providing a prescription, assessment or explanation of symptoms, follow-up of a previous episode of care, making or authorizing a referral, and general discussion of a health condition). RESULTS: Physicians reported providing care to secondary patients during 6% of their office visits. This care involved more than one category of service for the majority of visits involving care of a secondary patient. Advice was provided during more than half the visits. A prescription, assessment or explanation of symptoms, or a general discussion of condition were provided during approximately 30% of the secondary care visits. Secondary care was judged to have substituted for a separate visit 60% of the time, added an average of 5 minutes to the visit, and yielded no reimbursement for 95% of visits. CONCLUSIONS: Care of a secondary patient reflects the provision of potentially intensive and complex services that require additional time and are largely not reimbursed or recognized by current measures of primary care. This provision of secondary care may facilitate access to care and represent an added value provided by family physicians.
