ABSTRACT
BACKGROUND: Physical activity of resident physicians (RPs) during on-call shifts is difficult to objectively evaluate. The integration of smartphones in our daily routines may allow quantitative assessment, employing pedometric assessment. AIMS: To evaluate the number of steps that RPs walk during on-call shifts as a marker of physical activity by using smartphone-based pedometers. METHODS: Step counts were collected from 100 RPs' smartphones who volunteered to participate in the study between January 2018 and May 2019. The conversion rate was 1400 steps = 1 km (application's default). A shift was defined as regular morning work followed by an in-house on-call stay, totalling 26 hours. Statistical analyses included univariate and multivariate linear mixed models, and Fisher exact test. A P-value < 0.05 was considered statistically significant. RESULTS: The average walking distance was 12 118 steps (8.6 km/RP/shift). Paediatric intensive care unit and neurosurgery residents recorded the longest walking distances 16 347 and 15 630 steps (11.67 and 11.16 km/shift), respectively. Radiology residents walked the shortest distances 4718 steps (3.37 km/shift). Physically active RPs walked significantly longer distances during their shifts than non-physically active RPs: 12 527 steps versus 11 384 steps (8.95 versus 8.13 km/shift, P < 0.05), respectively. Distances covered during weekday shifts were longer than weekend shifts: 12 092 steps versus 11 570 steps (8.63 versus 8.26 km/shift, P < 0.05), respectively. CONCLUSIONS: Smartphone-based pedometers can aid in analysing physical activity and workload during on-call shifts; such information can be valuable for human resource department, occupational health authorities and medical students with impaired physical mobility when choosing a speciality.

PURPOSE: In this qualitative study it was investigated by group discussions with patients suffering from chronic heart failure, how relevant the existing quality indicators of the National Disease Management Guidelines for Chronic Heart Failure are being estimated. METHODS: 6 group discussions were performed. The sample was formed from 4 mixed-gender groups, a male group and a female group. Participants were recruited from local heart sports groups. For the interpretation a method similar to the grounded theory was used. RESULTS: The main conclusion is that in principle quality indicators are accepted. However, many of these indicators neglect the everyday aspects of patients' life. Participants show a disposition of "yes - but" regarding the quality indicators. This phenomenon could be theoretically grasped using the concept of order of knowledge. While participants keep referring to an order of everyday knowledge, quality indicators make recourse to a medical order of knowledge. Both orders of knowledge may compete with each other. CONCLUSIONS: The professional knowledge order of medicine needs to open up to a patients' knowledge order. Patient representatives in health care bodies need to be trained to develop a reflexive point of view to different knowledge orders enabling them to represent patients' everyday knowledge more confidently. Otherwise there is danger of conformation to the professional knowledge order of medicine only for reasons of being recognised as equal partners.

The purpose of this study was to develop normative data for step vergence testing in children age 6-12. Such data are not currently available for this age group. Base-in and base-out step vergence testing with a prism bar was performed on 386 elementary schoolchildren who had all passed a modified clinical technique (MCT) screening. A new polarized target was developed which enabled us to detect suppression, as well as diplopia or blur. The findings suggest significant differences from normative data previously reported for adults. Because the data for 6-year-olds were different from the rest of the group, we suggest that lower norms be used for this age group. This study provides expected findings for step vergence testing outside the phoropter, which can be used clinically for the assessment of disparity vergence ranges in young children.

Although accommodative facility testing is used widely in the evaluation of accommodation in children, published normative data are not available for this age group. Current values being used are based upon studies of adult populations. In order to establish norms, 542 elementary schoolchildren were screened. Those that passed a specific set of criteria were included in the accommodative facility assessment. We used a new target and instructional set, which took into consideration the problems associated with subjective testing of young children. The results revealed lower mean accommodative facility values for both monocular and binocular accommodative facility than the values obtained previously from adult populations. These new findings can be used as a clinical guide to evaluate accommodative facility in young children.

Experiments were performed to investigate the immune responses occurring as a result of partial hepatectomy (HEP) in mice. On Day 12 mice subjected to HEP showed a twofold rise in serum levels of IgG when compared with sham-operated (ShO) controls. The effects of HEP on specific antibody production following a single immunization with sheep red blood cells (SRBCs) were investigated. An early appearance of direct (IgM) splenic plaque-forming cells (PFCs) and significantly elevated indirect (IgG) PFCs were found in HEP mice. Elevated, early-appearing mercaptoethanol-resistant (IgG) hemagglutinating antibodies were also demonstrated in the sera of HEP mice. In addition to these findings our study showed that humoral and cell-mediated responses are affected by HEP in opposing fashion. Partial hepatectomy performed immediately after skin grafting suppressed a first set allograft rejection in mice. Furthermore, inhibited delayed-type hypersensitivity (DTH) response against SRBCs, as evaluated by a footpad weight assay, was demonstrated in HEP mice compared with the ShO controls. When SRBC-primed mice were partially hepatectomized 15 days later, they responded in a manner typical of the secondary immune response, showing an increased production of indirect (IgG) splenic PFCs. A similar anamnestic response was observed in mice sensitized with leptospiral antigen 50 days prior to HEP or exposed to carbon tetrachloride (CCl4) hepatotoxin. The mice responded by elevated serum IgG-specific antibodies as measured by solid-phase enzyme-linked immunosorbent assay (ELISA). Since HEP induced in mice immunological disturbances similar to those associated with liver disease, it is suggested that partial hepatectomy creating liver deficiency followed by regeneration may be a useful experimental model to study the immune status of various forms of hepatic damage.
