    Opis:
    Objectives Body surface area (BSA) is one of the major parameters used in several medical fields. However, there are concerns raised about its usefulness, mostly due to the ambiguity of its estimation. Material and Methods Authors have conducted a voluntary study to investigate BSA distribution and estimation in a group of 179 adult people of various sex, age, and physique. Here, there is provided an extended analysis of the majority of known BSA formulas. Furthermore, it was supplement with a comparison with the authors' propositions of enhanced formulas coefficients for known formulas models as well as with new power models based on an increased number of anthropometric data. Results Introduction of the enhanced formulas coefficients cause a reduction of at least 30.5% in mean absolute error and 21.1% in maximum error in comparison with their known counterparts. Conclusions In the context of the analysis presented it can be stated that the development of a single universal body surface area formula, based on a small number of state variables, is not possible. Therefore, it is necessary and justified to search for new estimation models that allow for quick and accurate calculation of body surface area for the entire population, regardless of individual body variations. The new formulas presented are such an alternative, which achieves better results than the previously known methods.

    Opis:
    The report aims to formulate an appropriate cardiac index (CI) model with 19 explanatory variables for 113 shock patients. Determinants of CI are focused from the fitted model. There is little study for the predicted factors of CI based on probabilistic modeling. CI model has been developed in the report with 19 explanatory variables for 113 shock patients, and the data site is: http://www.umass.edu/statdata/statdata/data/shock.txt Statistical method of joint generalized linear models (JGLMs) is adopted. Mean CI is negatively associated with age (P = 0.0044), shock type (SHOCKT) at level 3 (P = 0.0586), diastolic blood pressure (DBP) (P = 0.0032), mean circulation time (MCT) (P

    Opis:
    Peak expiratory flow rate (PEFR) varies with anthropometric variables like calendar age, body height, body weight, and body surface area in different regions. The present study aims at analyzing the relationship of PEFR with anthropometric variables to know a reference value in this region. We conducted the present study on healthy adult males aged eighteen to forty-five years engaged in works where they were un-exposed to pollutants in Patiala, India. Subgroups were made in each anthropometric variable category. PEFR recording was done using Mini Wright Peak Flow Meter. Results are expressed as mean PEFR ± standard deviation (mean ± S.D.), while the students' t-test was used to determine the differences between the means. We observed a linear increase in PEFR with all anthropometric variables. The correlation of PEFR with anthropometric variables was determined. PEFR is positively correlated with body height and body surface area (r =+0.20) and negatively correlated with calendar age (r = - 0.24) and body weight (r = - 0.02). We conclude that PEFR correlates best with body height (r = +0.48), and the result is highly significant (p < 0.01).

    Opis:
    W artykule przedstawiono strukturę opracowanego i wykonanego systemu komputerowego BSA Analysis Tool, wspomagającego procesy obliczeniowe wybranych parametrów organizmu człowieka: BSA, TBSA i BMI. W materiale, poza opisem systemu, wskazano na utylitarny charakter opracowania, szczególnie w przypadku: ośrodków medycznych - jako narzędzie wspomagające procesy leczenia oparzeń i chemioterapii oraz w ośrodkach naukowo-dydaktycznych jako narzędzie wspomagające procesy dydaktyczne.
    The paper describes in detail capabilities and a structure of the BSA Analysis Tool system which was developed for supporting the calculation and analysis process of human BSA (Body Surface Area), TBSA (Total Body Surface Area) and BMI (Body Mass Index). In some practical applications, the BSA coefficient can be determined using online calculators, but they are not that strongly developed. Moreover, the program allows calculating automatically the TBSA, replacing the hand-filled tables procedure. Advanced functions of the program allow for its use in medical centers as a tool assisting the treatment of burns or chemotherapy, as well as centers of research and teaching. The complex structure of the application consists of two main layers: clinical and scientific (Fig. 1). The BSA coefficient can be calculated on the basis of ten mostly used methods, while the value of the TBSA coefficient can be calculated on the basis of three methods. For calculating the BSA, only the most necessary data about the patients is required: body weight, height, age and gender, whereas the TBSA value in addition depends on the size of the body damaged area. The scientific layer structure is composed of three modules: comparison of methods for calculating the BSA, comparison of the BSA and BMI coefficients and analysis of the BSA surfaces. These tools enable a thorough analysis of the BSA coefficient (Figs. 2 and 3) as well as fast and accurate calculations of the BSA and TBSA.

    Opis:
    Parasites of the genus Ellobiopsis and epibiontic ciliates of the genus Paracineta were found on the body surface of some copepod taxa collected in the Kongsfjorden area (west Spitsbergen, Svalbard) during summer 2002. Paracineta sp. individuals were noted in Metridia longa and Paraeuchaeta norvegica (0.5% of the population infected in each species). This study provides the first record of the presence of Paracineta sp. in the latter species. Remarkably, epibionts were attached exclusively to females. Calanus finmarchicus and C. glacialis were invaded by Ellobiopsis spp., but the level of infection was generally low (0.06% and 0.09% of the population infected, respectively). Parasite distribution within both host populations was similar – 80% of infected specimens were at copepodid stage V. This study also provides the first record of C. glacialis serving as a host to Ellobiopsis.
