The Relation between Presenteeism and Different Types of Future Sickness Absence: Heidi JANSSENS, et al. Department of Public Health, Ghent University, Belgium—ObjectivesThe aim of this study was to examine the relation between sickness presenteeism and different types of future sickness absence in 2,983 Belgian middle‐aged workers.MethodsData were collected from 1,372 male and 1,611 female workers. Presenteeism was assessed by a single question, evaluating the frequency of occasions of going at work, despite illness, during the preceding year. Prospective, registered sickness absence data were collected during 12 months of follow‐up. Multivariate logistic regression models were used to investigate the relationship between presenteeism and short/long spells of absenteeism and high sickness absence frequency.ResultsHigh rates (>5 times) of presenteeism at baseline were significantly and independently associated with both long spells of sickness absence (at least 15 consecutive sick leave days) (men, OR=2.73, 95% CI=1.24−6.03; women, OR=2.40, 95%CI=1.31−4.40) and short spells of sickness absence (sick leave between1and3days)(men,OR=2.38,95%CI=1.25−4.51; women, OR=1.90, 95%CI=1.17−3.11) in both genders during one year follow‐up. Moderate rates (2−5 times) of presenteeism were significantly associated with long spells of sickness absence only in the male group (OR=1.90, 95%CI= 1.21−2.97). With regard to high sickness frequency (at least 3 sick leave episodes), a significant and positive association with high rates of presenteeism was demonstrated only in the female workers (OR=2.38, 95%CI=1.40−4.04).ConclusionsThese results suggest that presenteeism was related to different types of future sickness absence.

A Prioritization Approach for Noise Risk Management in a Petrochemical Complex: Parvin NASSIRI, et al. Department of Occupational Health, School of Public Health, Tehran University of Medical Sciences, Iran—ObjectivesNoise is probably the most common occupational hazard facing workers today. This paper presents a model to evaluate and select a unit as the first priority for implementing noise control measures from the different parts of an industrial complex.MethodsFor this purpose, a formula was proposed as a priority risk index (NCPI) by considering some criteria, including: the number of exposed workers in each part, their exposure times and the range of sound pressure level. The above criteria were weighed by appending weighting factors, which can be different based upon the environmental noise levels. The environmental noise measurements were also carried out by lattice method according to ISO 9612:2009. At the next stage, the numbers of stations that fell within the desired ranges in the weighting factors table were found. Then the priorities were identified using the above criteria and the NCPI.ResultsThe results indicate that the compression unit of air plant had the highest score among the different departments of the company under study (NCPI=0.3). Using this model is easy and fast. It is applicable to similar industries and also offers valuable information for prioritizing noise control measures.ConclusionsTherefore, it will be possible to minimize worker exposure to noise in the most polluted places in any industry by identifying the main noise sources and implementing measures suitable for controlling the risk.

OBJECTIVE:To establish the biochemical characteristics of nonobese, overweight, and obese children as well as to determine the risk factors associated with insulin resistance in nonobese children and with non–insulin resistance in obese children in the age strata of 6 to 11 years.METHODS:A total of 3512 healthy children were enrolled in a cross-sectional study. In the absence of obesity, fasting hyperinsulinemia and hypertriglyceridemia defined nonobese, insulin-resistant (NO-IR) children. In the absence of metabolic abnormalities of fasting insulin and triglycerides levels, obese children were defined as obese, not insulin-resistant (O-NIR) children.RESULTS:The gender- and age-adjusted prevalence of NO-IR and O-NIR was 6.6% and 21.3%, respectively. In the age-, gender-, and birth weight–adjusted analysis, family history of hypertension (FHH) in both maternal and paternal branches (odds ratio [OR]: 1.514; 95% confidence interval [CI]: 1.2–3.9; P = .04) was associated with NO-IR children. In the analysis adjusted by gender, age, waist circumference (WC), BMI, FHH, and family history of diabetes, high birth weight was associated with NO-IR children (OR: 1.319; 95% CI: 1.2–2.1; P = .04). Finally, in the gender-, age-, family history–, and birth weight–adjusted analysis, a WC lower than the 95th percentile was associated with a lower odds of insulin resistance among obese children (OR: 0.96; 95% CI: 0.91–0.98; P &lt; .0005).CONCLUSIONS:FHH and high birth weight are associated with NO-IR children, and a low WC is associated with lower odds of O-IR children.

Published: March 2013

OBJECTIVE:
To assess the risk of pertussis by time since vaccination in children in Minnesota and Oregon who received 5 doses of acellular pertussis vaccines (DTaP).

METHODS:
These cohort analyses included Minnesota and Oregon children born between 1998 and 2003 who had 5 DTaP doses recorded in state Immunization Information Systems. Immunization records and statewide pertussis surveillance data were combined. Incidence rates and risk ratios for pertussis were calculated for the 6 years after receipt of the fifth DTaP dose.

RESULTS:
The cohorts included 224 378 Minnesota children and 179 011 from Oregon; 458 and 89 pertussis cases were identified in Minnesota and Oregon, respectively. Pertussis incidence rates rose each year of follow-up: 15.6/100 000 (95% confidence interval [CI]: 11.1–21.4) at year 1 to 138.4/100 000 (CI: 113.3–166.9) at year 6 (Minnesota); 6.2/100 000 (CI: 3.3–10.6) in year 1 to 24.4/100 000 (CI: 15.0–37.8) in year 6 (Oregon). Risk ratios increased from 1.9 (CI: 1.3–2.9) in year 2 to 8.9 (CI: 6.0–13.0) in year 6 (Minnesota) and from 1.3 (CI: 0.6–2.8) in year 2 to 4.0 (CI: 1.9–8.4) in year 6 (Oregon).

CONCLUSIONS:
This evaluation reports steady increase in risk of pertussis in the years after completion of the 5-dose DTaP series. This rise is likely attributable in part to waning immunity from DTaP vaccines. Continuing to monitor disease burden and vaccine effectiveness in fully vaccinated children in coming years will be important to assess ongoing risk as additional cohorts vaccinated solely with acellular pertussis vaccines are introduced.

Published: March 2013

OBJECTIVE:
To assess the effects of electronic health record–based clinical decision support (CDS) and physician performance feedback on adherence to guidelines for acute otitis media (AOM) and otitis media with effusion (OME).

METHODS:
We conducted a factorial-design cluster randomized trial with primary care practices (n = 24) as the unit of randomization and visits as the unit of analysis. Between December 2007 and September 2010, data were collected from 139 305 otitis media visits made by 55 779 children aged 2 months to 12 years. When activated, the CDS system provided guideline-based recommendations individualized to the patient’s history and presentation. Monthly physician feedback reported adherence to guideline-based care, changes over time, and comparisons to others in the practice and network.

RESULTS:
Comprehensive care (all recommended guidelines were adhered to) was accomplished for 15% of AOM and 5% of OME visits during the baseline period. The increase from baseline to intervention periods in adherence to guidelines was larger for CDS compared with non-CDS visits for comprehensive care, pain treatment, adequate diagnostic evaluation for OME, and amoxicillin as first-line therapy for AOM. Although performance feedback was associated with improved antibiotic prescribing for AOM and pain treatment, the joint effects of CDS and feedback on guideline adherence were not additive. There was marked variation in use of the CDS system, ranging from 5% to 45% visits across practices.

CONCLUSIONS:
Clinical decision support and performance feedback are both effective strategies for improving adherence to otitis media guidelines. However, combining the 2 interventions is no better than either delivered alone.

Published: March 2013

OBJECTIVE:
To develop and evaluate a system for reliable and efficient individualized risk-based monitoring of cholesterol and 11 other tests after kidney transplantation in children.

METHODS:
We identified system components that drive reliable individualized monitoring and used quality improvement methods to develop and implement interventions, including (1) monitoring schedules individualized by dyslipidemia risk assigned to each patient, (2) automated previsit decision support from our electronic medical record, (3) standardized work flow and responsibility, and (4) automated forwarding of results to providers. We measured the proportion of patients due for cholesterol testing who had it performed within 1 week of their clinic visit and the proportion of patients in our population who achieved low-density lipoprotein (LDL) cholesterol control at baseline and for 2 years after improved monitoring.

RESULTS:
The proportion of visits in which cholesterol monitoring was completed when indicated improved from 80% to 98% within 8 months and was sustained for more than 1 year. The number of patients with controlled LDL (&lt;130 mg/dL, 3.3 mmol/L) improved from 44 (71%) of 62 at the start of our project to 58 (94%) of 62 (P = .002) at an average follow-up of 24 months.

CONCLUSIONS:
Using quality improvement and health information technology, we achieved sustained, reliable and efficient personalized monitoring of cholesterol and 11 other tests. This approach enabled substantial improvement in LDL cholesterol control. Structured methods of system redesign that leverage information technology systems hold promise for rapidly achieving reliable individualized care in other settings.
Baby-Friendly Hospital Accreditation, In-Hospital Care Practices, and Breastfeeding
Authors: Brodribb Wendy , Kruske Sue , Miller Yvette D. 
Published: March 2013

OBJECTIVES:
To investigate the effect of Baby-Friendly Hospital Initiative (BFHI) accreditation and hospital care practices on breastfeeding rates at 1 and 4 months.

METHODS:
All women who birthed in Queensland, Australia, from February 1 to May 31, 2010, received a survey 4 months postpartum. Maternal, infant, and hospital characteristics; pregnancy and birth complications; and infant feeding outcomes were measured.

RESULTS:
Sample size was 6752 women. Breastfeeding initiation rates were high (96%) and similar in BFHI-accredited and nonaccredited hospitals. After adjustment for significant maternal, infant, clinical, and hospital variables, women who birthed in BFHI-accredited hospitals had significantly lower odds of breastfeeding at 1 month (adjusted odds ratio 0.72, 95% confidence interval 0.58–0.90) than those who birthed in non–BFHI-accredited hospitals. BFHI accreditation did not affect the odds of breastfeeding at 4 months or exclusive breastfeeding at 1 or 4 months. Four in-hospital practices (early skin-to-skin contact, attempted breastfeeding within the first hour, rooming-in, and no in-hospital supplementation) were experienced by 70% to 80% of mothers, with 50.3% experiencing all 4. Women who experienced all 4 hospital practices had higher odds of breastfeeding at 1 month (adjusted odds ratio 2.20, 95% confidence interval 1.78–2.71) and 4 months (adjusted odds ratio 2.93, 95% confidence interval 2.40–3.60) than women who experienced fewer than 4.

CONCLUSIONS:
When breastfeeding-initiation rates are high and evidence-based practices that support breastfeeding are common within the hospital environment, BFHI accreditation per se has little effect on both exclusive or any breastfeeding rates.
Simultaneous Nitrification and Denitrification in an SBR with a Modified Cycle During Reject Water Treatment
Authors: Bernat Katarzyna 
Published: March 2013

Abstract
In this study, the dependence between volumetric exchange rate (n) in an SBR (Sequencing Batch Reactor) with a modified cycle and simultaneous nitrification and denitrification (SND) efficiency during the treatment of anaerobic sludge digester supernatant was determined. In the SBR cycle alternating three aeration phases (with limited dissolved oxygen (DO) concentration up to 0.7 mg O2/L) and two mixing phases were applied. The lengths of each aeration and mixing phases were 4 and 5.5 h, respectively. Independently of n, a total removal of ammonium was achieved. However, at n = 0.1 d-1 and n = 0.3 d-1 nitrates were the main product of nitrification, while at n = 0.5 d-1, both nitrates and nitrites occurred in the effluent. Under these operational conditions, despite low COD/N (ca. 4) ratio in the influent, denitrification in activated sludge was observed. A higher denitrification efficiency at n = 0.5 d-1 (51.3%) than at n = 0.1 d-1 (7.8%) indicated that n was a crucial factor influencing SND via nitrite and nitrate in the SBR with a low oxygen concentration in aeration phases.

Published: March 2013

Abstract
The paper presents results of floristic investigation conducted within the territory of waste dumps in Lower Silesia: landfill of municipal waste Wrocław-Maślice, post-metallurgic waste heap in Siechnice, serpentine dumping grounds in Grochów and slag heaps in Bielawa.
The investigated flora was analyzed with regard to species composition, participation of geographical-historical groups, live forms (according to classification by Raunkiaer), as well as selected ecological factors: light indicator (L), thermal indicator (T), soil moisture (W), trophic indicator (Tr), soil reaction (pH), value of resistance to increased heavy metals content (M). On 4 waste dumps there were found 269 species of vascular plants, belonging to 51 families. Only 5 species occurred on 4 sites, which provides for 2% of all plants recorded. The most numerous families are Asteraceae, Poaceae and Fabaceae. Apophytes dominate in waste dumps flora Hemicryptophytes are the most numerous group.
Analysis of the floras (selected ecological factors) of investigated objects has shown general similarities, but also apparent differences. The most significant differences concerned two parameters: trophism (Tr) and resistance to increased heavy metals content (M).
The history of Lake Rzecin and its surroundings drawn on maps as a background to palaeoecological reconstruction
Authors: Barabach Jan 
Published: March 2013

AbstractThe article presents the results of landscape analysis of the surroundings of Lake Rzecin in Noteć Forest depicted on cartographic materials. Morphometrical analysis and analysis of changes in the water conditions of Lake Rzecin were conducted. Thanks to many cartographic data, changes in lake geometry could be observed during almost the whole of the last two centuries. The results show that the major impact on the rate of lake level decrease in the last two hundred years was due to melioration works. Two periods of rapid decrease in the lake surface can be observed during this time. The first occurred as a result of the creation of Rzecin Ditch, which probably took place in the middle of the 19th century; the second, in all likelihood, with its cleaning out; the exact date of this operation is not known but the results of map analysis suggest that it could have happened between 1958 and 1966. Due to these two events the lake surface decreased by 73.6% during the analysed period. Apart from this phenomenon the lake surface area seems to be quite stable: there were some fluctuations; however, changes did not exceed more than 5%. That is why it can be assumed that the human factor has the biggest influence on succession rate of the lake ecosystem. Analysis of the map collection shows that during the last two centuries there were no huge changes in the local landscape; however, other historical sources do not confirm this. According to them, not only man but also fires and insect gradations had an enormous influence on the Noteć Forest ecosystem. Nonetheless, land use structure within the Rzecin Ditch catchment area did not change a great deal; the most significant modification was the increment of forested areas from 74.1 up to 85.1 %.
Efficiency of pulverizing aeration on Lake Panieńskie
Authors: Osuch Ewa , Podsiadłowski Stanisław 
Published: March 2013

AbstractThe principal threat to lakes of the temperate zone is posed by factors accelerating their eutrophication and causing marked deoxygenation of the deeper layers of water, mainly the hypo- and metalimnion. Among their effects are frequent phytoplankton blooms, including those of blue-green algae, and general deterioration of water quality also affecting the abundance and health status of fish. The chief concern is a disturbed proportion between the quantity of complex chemical compounds, especially organic, and the oxygen content of lake waters. Natural processes of water oxygenation are not too intensive, because they are practically limited to the epilimnion layer, connected as they are with the activity of aquatic plants of the littoral and sublittoral zone (which tends to disappear in contaminated lakes) and wind energy (the effect of waving). In summer conditions, with a relatively great chemical activity of bottom deposits, the intensity of those processes is usually inadequate. Hence, in 1995 research was launched in the Institute of Agricultural Engineering of the Agricultural University in Poznań on an integrated lake restoration technology whose core was a self-powered aerator capable of oxygenating also the bottom layers of water (the hypolimnion) of deep lakes. The aerator uses energy obtained from a Savonius rotor mainly to diffuse gases: to release hydrogen sulphide, which usually saturates the hypolimnion water completely, and then to saturate this water with oxygen. Even early studies showed the constructed device to be highly efficient in improving oxygen conditions in the bottom zone. They also made it clear that it should be equipped with an autonomous system designed to inactivate phosphorus, one of the principal factors determining the rate of lake degradation. In 2003 the first wind-driven pulverizing aerator equipped with such a system was installed in Lake Urban in Chodzież. The aim of this work is to present the principles of operation of a wind-driven pulverizing aerator with a phosphorus inactivation system, as well as its general technical characteristics and preliminary results of a study of its performance.
Changes in the water surface area of Lakes Udzierz and Mątasek in the light of cartographic materials
Authors: Fabich Andrzej , Kwidzińska Monika 
Published: March 2013

AbstractThe paper presents the changes in the water surface area of Lakes Udzierz and Mątasek located in the headwaters of the catchment of the River Mątawa (tributary of the River Vistula). The assessment of the rate of changes was based on Polish and German topographic maps as well as orthophotomaps. The analysed lakes turned out to be two of the fastest disappearing Polish lakes. In the last century (1910-2010) the water surface area of Lake Udzierz decreased from 148.87 to 69.60 ha and that of Lake Mątasek from 29.5 to 0.64 ha. The average rate of loss of the lake surface area during this period was from 0.53 to 0.98% per annum. Such drastic morphometric changes in the studied lakes are, on the one hand, mainly due to poorly conducted drainage and, on the other hand, the eutrophication of the lake waters intensified by the anthropogenic impact.

AbstractThe aim of this study was to determine the chemical composition of Lake Widryńskie bottom sediments (max. depth. 27.0 m, area 123.9 ha). The sampling of bottom sediments was conducted once, on 16 August 2010. Sampling was made in 10 specific areas. Among the 10 samples, 4 samples were taken from the littoral and sublittoral zones, while the rest were taken from the profundal zone. The dominant component of the sediments was silica and calcium carbonates were subdominant. Based on the survey, it was determined that silica occurred in greater numbers in littoral sediments, while in sublittoral sediments there was increased participation in the chemical composition of organic matter. The elements that build a capacity complex were a small percentage of the dry weight of sediment. Sediment from the vicinity of inflows contains higher amounts of silica, which confirmed the impact of the catchment on the chemical composition of sediments.

Authors: Thakur Chandrakant , Deo Mall Indra , Srivastava Vimal Chandra 
Published: March 2013

Abstract
In the present study, treatment of synthetic wastewater containing phenol, resorcinol and catechol was studied in a sequencing batch reactor (SBR). Parameters such as hydraulic retention time (HRT) and filling time have been optimized to increase the phenol, resorcinol, catechol and chemical oxygen demand (COD) removal efficiencies. More than 99% phenol, 95% resorcinol and 96% catechol and 89% COD removal efficiency was obtained at optimum conditions of HRT = 1.25 d and fill time = 1.5 h. The heating value of the sludge was found to be 12 MJ/kg. The sludge can be combusted to recover its energy value.

Published: March 2013

Abstract
Introduction: Remote cerebellar hemorrhage is an infrequent complication, potentially harmful with an unclear etiologic mechanism.
There may be incriminated multiple risk factors: arterial hypertension, use of antiplatelet medication (Aspenter), CSF aspiration or drainage associated with intracranial hypotension.
Material and methods: We present a 69 year old woman with remote intracerebral hemorrhage that occurred after frontal parasagittal meningioma resection.
Results: An inadequate oral hydration was responsible for decreased level of consciousness, cerebellar and parietaloccipital cortical-sub-cortical contra-lateral hemorrhages. Close monitoring of water balance and adequate hydration is related to clinical improvement and resolution of brain imaging.
Conclusion: Retraction of the brain due to intracranial hypotension led to some small vessels rupture and development of remote cerebellar hemorrhage.
