Abstract
Peripherally inserted central catheters (PICCs) play a critical role in neonatal intensive care units (NICUs), facilitating treatment in premature and critically ill neonates. However, achieving optimal PICC placement can present challenges, requiring meticulous monitoring and adjustment. Here, we describe the case of a 52-day-old, 1.9 kg preterm infant in the NICU requiring a central venous catheter for antibiotics and antifungals. Despite initial insertion into the basilic vein of the right forearm, imaging revealed the catheter's deviation into the right internal jugular vein. Leveraging the influence of arm position on catheter tip depth, external manipulation of the infant's right arm successfully repositioned the catheter tip into the superior vena cava (SVC). This case highlights the significant impact of arm positioning on PICC placement and underscores the efficacy of external extremity manipulation as a simple, non-invasive technique to adjust catheter position. Such innovative strategies offer promising alternatives to invasive interventions, emphasizing the importance of dynamic monitoring and adjustment techniques in neonatal PICC management.

Role of a radiopaque agent and surveillance radiographs for peripherally inserted central catheters in newborn infants. Pediatr Radiol 2023; 53:2235-2244. [PMID: 37490126 PMCID: PMC10562302 DOI: 10.1007/s00247-023-05705-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 06/13/2023] [Accepted: 06/14/2023] [Indexed: 07/26/2023]
Abstract
BACKGROUND Controversy exists regarding the use of a radiopaque agent to identify peripherally inserted central catheter (PICC) tip positions in newborn infants and of serial radiography to monitor PICC tip migration. OBJECTIVE To investigate the roles of (1) the injection of a radiopaque agent to identify PICC tip position and (2) the performance of weekly radiography to monitor PICC migration. MATERIALS AND METHODS This retrospective single-centre cohort study included newborn infants who received a PICC between 1 January 2016 and 31 December 2020. A radiopaque agent was injected to identify PICC tip position and radiographs were performed weekly to detect PICC migration. RESULTS We identified 676 PICC episodes in 601 infants. A radiopaque agent was used for 590 of these episodes. There was no difference in the proportion of central PICC tip positions based on radiopaque agent use status (490/590, 83% for the radiopaque agent used group versus 73/85, 85.8% for the radiopaque agent not used group, P=0.51). Irrespective of the site of PICC insertion, outward migration was observed for most centrally placed PICCs over their entire in situ duration. Inward migration was identified in 23 out of 643 PICC episodes (3.6%) only on radiographs obtained on or before day 7. Based on serial radiographs, the odds for PICC tips remaining in a central position were lower the longer the PICC remained in situ (adjusted odds ratio-OR 0.93; 95% confidence interval 0.92-0.95). There was no difference in PICC migration between side and limb of insertion. CONCLUSION PICC tips can be identified without injection of a radiopaque agent. Serial radiographs identified PICC migration over the in situ duration. This study has implications for reducing exposure to a radiopaque agent and ongoing migration surveillance practices.

Abstract
OBJECTIVE To assess point-of-care-ultrasound (POCUS) guided catheter tip location in a neonatal cohort after insertion of percutaneously inserted central catheters (PICCs) from the upper part of the body. STUDY DESIGN This was a prospective, observational study on PICC tip location. Tip site was assessed by radiological landmarks or direct ultrasound (US) visualization of the cardiovascular structures. RESULTS One hundred eighteen PICCs (28Gauge/1French) were studied in 102 neonates (mean postmenstrual age 31 weeks, range 25-43 weeks; mean weight at positioning 1365 g, range 420-4180 g). Feasibility of POCUS guided tip location was 92.3% in our population. Failures were significantly associated with mechanical ventilation (aOR 5.33; 95% CI 1.13-29.5; P = .038). Agreement between US and radiographic methods was found in 88 of 109 cases (80.7%). Fifteen of 21 discordant cases led to a change in clinical management. CONCLUSIONS POCUS guided localization of small bore PICC is a non-invasive and effective alternative to the conventional radiogram. The latter should be recommended when US examination fails to locate the catheter tip.

The role of ultrasonography for detecting tip location of percutaneous central venous catheters in neonates-a single-center, prospective cohort study. Pediatr Neonatol 2021; 62:265-270. [PMID: 33637475 DOI: 10.1016/j.pedneo.2021.01.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2020] [Revised: 09/17/2020] [Accepted: 01/19/2021] [Indexed: 10/22/2022] Open
Abstract
BACKGROUND Percutaneous central venous catheters (PCVCs) are used commonly and widely in the neonatal intensive care unit (NICU). Malposition of PCVCs may cause life-threatening complications and prolong hospitalization. In Taiwan, conventional chest-abdomen radiography (CXR) has been used widely and routinely for assessing tip location of PCVCs. Compared to ultrasonography (US), CXR cannot provide real-time assessment, and patients are exposed to radiation. Therefore, this study aimed to analyze the role of US in detecting PCVC tip location in the lower extremities. METHODS Neonates who received PCVC insertion in the lower extremities in NICU from March 2019 to April 2020 were enrolled in this prospective cohort study. PCVC tip location was confirmed finally by conventional CXR after US examination and patients were included in the sono group; those not assessed by US formed the non-sono group. In addition, PCVCs inserted in 2018 for which tip location was evaluated only by CXR, were reviewed retrospectively and these cases were included in the non-sono group. Withdrawal rates between the two groups were analyzed using Chi-square test. RESULTS The sono group included 166 neonates with PCVCs and 141 were in the non-sono group. Median gestational age at date of PCVC insertion was 33.21 and 32.71 weeks in sono and non-sono groups, respectively (p = 0.37). Withdrawal rates were 10.84% and 65.95% (p < 0.001) and duration for catheter location confirmation were 2-4.75 min and 75-247.25 min (p < 0.001), respectively. CONCLUSION US provides more reliable images than conventional radiography alone for identifying PCVC tip locations in the lower extremities. It can effectively reduce catheter insertion duration, and was associated with fewer manipulations.

Does ultrasound guidance for peripherally inserted central catheter (PICC) insertion reduce the incidence of tip malposition? - a randomized trial. J Perinatol 2019; 39:95-101. [PMID: 30348962 DOI: 10.1038/s41372-018-0249-x] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2018] [Revised: 09/25/2018] [Accepted: 10/01/2018] [Indexed: 11/08/2022]
Abstract
OBJECTIVE The aim of the study was to evaluate the incidence of peripheral inserted central catheter (PICC) tip malposition when the catheter is inserted under real-time ultrasound (RTUS) guidance when compared with conventional landmark (CL) technique in neonates. Additional objectives were to evaluate the PICC longevity and central line associated blood stream infections (CLABSI). STUDY DESIGN In this randomised controlled trial, neonates were randomised to 'RTUS' (n = 40) or 'CL' (n = 40) groups. PICC tip was placed under ultrasound guidance in lower third of superior vena cava in the RTUS group. In 'CL' group, PICC was inserted as calculated by anatomical landmarks. RESULTS The birth weight (1286 (926, 1662) vs. 1061 (889, 1636) g) and gestation (31.12 (3.1) vs. 31.4 (3.6) wks) were comparable among the groups. RTUS guidance during PICC insertion reduced incidence of tip malposition by 52% (67.5 vs. 32.5%; RR: 0.48; 95% CI: 0.29-0.79). The longevity of PICC and episodes of CLABSI were however similar in the two groups. CONCLUSIONS Real-time ultrasound guidance during PICC placement reduces the incidence of tip malposition.

Abstract
UNLABELLED To propose a response criterion for analyzing the intervention success by verifying patient outcomes after a multidisciplinary obesity treatment program in Brazilian children and adolescents. Obese children and adolescents (n = 103) completed a 16-week multidisciplinary intervention (IG) and were compared to the control group (CG) (n = 66). A cluster of parameters (e.g. total domain of HRQoL; BMI z-score; cardiorespiratory fitness; body mass; waist circumference; fat mass; lean mass) were measured pre and post-intervention, and the sum of the median percentage variation and the percentile 25 and 75 were used from IG and CG to determine the responsiveness to the program. We are proposing four ranges in which children and adolescents may be classified after the intervention: (1) CG percentile 50 values or lower are considered non-responsive to the intervention, (2) values greater than CG percentile 50 but lower than IG percentile 50 are considered slightly responsive, (3) values greater than IG percentile 50 but lower than IG percentile 75 were considered as moderately responsive, and (4) values greater than IG percentile 75 were considered very responsive. CONCLUSIONS This criterion may serve as a complementary tool that can be employed to monitor the response to this model of multidisciplinary intervention. What is Known: • The effectiveness of multidisciplinary obesity interventions is usually determined by comparing changes in selected outcomes in the intervention versus versus control group. • There is no consensus about what should be assessed before and after the intervention program, which makes difficult to compare different programs and to determine their rate of responsiveness. What is New: • This study proposes a response criteria to pediatric obesity interventions following a similar model compared to ours based on key variables that presents low cost and high applicability in different settings.

Abstract
A preterm neonate born at 27 weeks, with a birth weight of 555 g, was on continuous positive airway pressure (CPAP) for apnoea of prematurity and initially received total parenteral nutrition (TPN) through the umbilical venous catheter. Peripherally inserted central catheter (PICC) was inserted in the left basilica vein on day 8 to continue TPN. The baby developed respiratory distress with persistent hypoxia after TPN was initiated through the PICC line. The baby required mechanical ventilation due to worsening of respiratory distress, and chest X-ray, as well as ultrasound conducted 12 hours, postinfusion of TPN revealed right-sided pleural effusion. On careful observation, we could trace the PICC in the right lung area. The PICC line was removed immediately and the baby improved over the next 18 hours and was extubated to CPAP within the next 48 hours. We report this case of contralateral pleural effusion secondary to malposition of PICC line in an extremely preterm neonate.

Abstract
AIM To establish how neonatal units in England and Wales currently confirm longline tip position, immediately after insertion of a longline.
METHODS We conducted a telephone survey of 170 neonatal units (37 special care baby units, 81 local neonatal units and 52 neonatal intensive care units) across England and Wales over the period from January to May 2016. Data was collected on specifically designed proformas. We gathered information on the following: Unit Level designation; whether the unit used longlines and specific type used? Modality used to confirm longline tip position? Whether guide wires were routinely removed and contrast injected to determine longline position? The responders were primarily senior nurses.
RESULTS We had 100% response rate. Out of the total neonatal units surveyed (170) in England and Wales, 141 units (83%) used longlines. Fifty-five out of 81 local neonatal units (68%) using longlines, used ones that came with guide wires; a similar percentage of neonatal intensive care units, i.e., 31 out of 52 units (60%) did the same. All of those units used radiography, plain X-rays, to establish longline tip position. Out of 55 local neonatal units using longlines with guide wires, 42 (76%) were not removing wire to use contrast while this figure was 58% (18 out of 31 units) for neonatal intensive care units. Overall, only 49 out of 141 units (35%) of the units using longlines were using contrast. However it was interesting to note that use of contrast increased as one moved from special care baby units (25%, 2 out of 8 units) to local neonatal units (28%, 23 out of 81 units) and neonatal intensive care units level (46%, 24 out of 52 units) designation.
CONCLUSION Neonatal units in England and Wales are overwhelmingly relying on plain radiographs to assess longline tip position immediately after insertion. Despite evidence of its usefulness, and in the absence of perhaps more accurate methods of assessing longline tip position in a reliable and consistent way, i.e., ultrasonography, contrast is only used in a third of units.

Abstract
OBJECTIVE To evaluate and compare physical activity and physical fitness among urban school children and their rural counterparts. METHODS This cross sectional study included children aged between 9 and 13 y in eight middle schools; 4 urban and 4 rural. Data on health related fitness parameters was obtained by using the procedures described in the Euro fit physical fitness test manual. The data regarding physical activity was collected by using the Self Administered Physical Activity Checklist (SAPAC). RESULTS Six hundred and fifty subjects (341 rural and 309 urban) with the mean age 10.84 in rural and 10.85 in urban were included. This study showed statistically significant differences in the height, weight, BMI and SAPAC score between the rural and urban children. Also, rural children were more flexible (mean SRT = 23.42 cm) with a good cardiovascular endurance when compared to their urban counterparts. CONCLUSIONS The results reveal that rural children performed better in flexibility and cardio vascular endurance tests when compared to their urban counterparts. Promotion of health related fitness involves physical activity associated with weight management which is the prime need of the hour.

Abstract
The study aims to assess the association of diet and frequency of extracurricular physical activity (PA) on blood pressure (BP) in non-obese adolescents. A total of 7185 non-obese adolescents aged 12-18 years were analysed to elucidate the relationship between BP and exercise/eating habit. Totally, 10.3% of the boys and 4.6% of the girls who responded to the questionnaire reported undertaking regular extracurricular physical exercise > or =3 times/week and were classified as being physically active. An unhealthy eating habit (UEH) score was constructed by counting the number of 'yes' responses to 11 dietary behavioural items considered to be unhealthy. In logistic regression analysis, age, body mass index, exercise frequency and UEH were significantly associated with BP (P<0.001). The odds ratios (ORs) for high BP in physically more active adolescents vs those who were less active was 0.48 (95% confidence interval (CI) 0.30-0.77). The OR for high BP in those with UEH scores in the highest quartile vs those with UEH scores in the lowest quartile was 1.63 (95% CI 1.24-2.15). In conclusion, regular exercise and a healthy diet are positively associated with lower BP even in non-obese adolescents.

Abstract
Background In adults, there is a substantial body of evidence that physical inactivity or low cardiorespiratory fitness levels are strongly associated with the development of metabolic syndrome. Although this association has been studied extensively in adults, little is known regarding this association in adolescents. The aim of this study was to analyze the association between physical activity and cardiorespiratory fitness levels with metabolic syndrome in Brazilian adolescents. Methods A random sample of 223 girls (mean age, 14.4 ± 1.6 years) and 233 boys (mean age, 14.6 ± 1.6 years) was selected for the study. The level of physical activity was determined by the Bouchard three-day physical activity record. Cardiorespiratory fitness was estimated by the Leger 20-meter shuttle run test. The metabolic syndrome components assessed included waist circumference, blood pressure, HDL-cholesterol, triglycerides, and fasting plasma glucose levels. Independent Student t-tests were used to assess gender differences. The associations between physical activity and cardiorespiratory fitness with the presence of metabolic syndrome were calculated using logistic regression models adjusted for age and gender. Results A high prevalence of metabolic syndrome was observed in inactive adolescents (males, 11.4%; females, 7.2%) and adolescents with low cardiorespiratory fitness levels (males, 13.9%; females, 8.6%). A significant relationship existed between metabolic syndrome and low cardiorespiratory fitness (OR, 3.0 [1.13-7.94]). Conclusion The prevalence of metabolic syndrome is high among adolescents who are inactive and those with low cardiorespiratory fitness. Prevention strategies for metabolic syndrome should concentrate on enhancing fitness levels early in life.

Abstract
The main aim of this study was to determine the extent to which physical activity and adiposity are associated with blood cholesterol levels in male adolescents. Anthropometric and physical fitness values were measured in all children. Body mass index (BMI) and physical activity index (PAI) were used to split participants into active overweight (ACO) and non-active normal-weight (NAN) groups. The cutoffs for the ACO group were BMI > or = 22.6 kg/m2 and PAI > or = 3.5, respectively, whereas the corresponding cutoffs for the NAN groups were BMI < 20.0 kg/m2 and PAI < 2. A total of 65 children (29 in ACO group, 36 in NAN group) were selected according to the above criteria. ACO group showed significantly higher BMI and body fat as compared to their NAN counterparts (p < 0.05). Adolescents from ACO group attained superior scores for PAI and aerobic fitness (p < 0.05). Most blood lipid variables were significantly lower in ACO group as compared to NAN (p < 0.05) while HDL-cholesterol was higher in ACO group (p < 0.05). There was significant positive correlation between HDL-cholesterol and PAI in ACO group (r = 0.38; p < 0.05). The physical activity index explained the majority of variance in HDL-cholesterol for ACO group (beta = 0.513; p < 0.05). It seems that physical activity in adolescents is a more important factor in balancing blood lipid status than adiposity per se, particularly for HDL-cholesterol.

Abstract
OBJECTIVE In neonates, proper positioning of the tip of intravenous long lines (LL) is essential in order to prevent potential life-threatening complications. The gold standard for the evaluation of LL position in neonates is the chest X-ray with or without contrast. We performed a prospective study to assess the use of transthoracic ultrasonography (US) for the positioning of LL in neonates and to compare it to plain radiography. MATERIALS AND METHOD Thirty-six consecutive neonates requiring percutaneous LL over a period of 3 months were included in the study. Immediately after LL insertion, the position of its tip was verified using transthoracic US, followed by plain radiography. The two techniques were compared in terms of adequate placement and length of time between insertion and radiographic evaluation of the correct position. RESULTS The correlation between positioning by US and plain radiography was very good (r=0.97, r(2)=0.94, p<0.0001). The time needed to verify LL placement by US was shorter by a mean 15 min compared to plain radiography. CONCLUSION US can accurately guide LL tip positioning. We believe that because of the potential gain of time it offers and its lack of ionising radiation, it to be considered as an interesting tool for the positioning of LL in neonates. Yet more accurate results could be obtained with a better-trained staff.

Abstract
BACKGROUND The position of percutaneously inserted central venous catheters (longlines) in neonates is critical, as malpositioned longlines are associated with potentially fatal complications. AIM To determine if cardiac ultrasound (two-dimensional (2D) and colour Doppler) is useful in evaluating longline position, when compared with the position identified by contrast radiography. SETTING Single level 3 neonatal unit. PARTICIPANTS Forty-four neonates undergoing insertion of 24-gauge silastic longlines between July 2004 and September 2005. METHODS Infants who had a longline inserted underwent echocardiography by a novice and an experienced operator. Operators identified longline position using a 2D then colour Doppler echocardiography during a rapid bolus infusion of saline. The position was identified from contrast radiography by two independent observers. RESULTS Using 2D echocardiography, the novice and experienced operators could identify 41 and 59% of longlines, respectively. However, only 34% of longlines were identified by both operators. In 15 infants whose longline positions were identified by both operators, there was agreement in only eight infants (53%). Colour Doppler improved the experienced operator's success but did not assist the novice operator. For radiographs, there was 68% agreement on longline position between observers. The experienced echocardiographer located three (7%) longlines within the heart that from radiographs were thought to be in a proximal central vessel. CONCLUSIONS This technique is experience-dependent and complements rather than replaces the use of contrast radiography. However, some infants with an apparently acceptable longline position on contrast radiography have longlines located within the heart on echocardiography.

Abstract
BACKGROUND/AIMS Obesity among adolescents is a significant and global disease which requires early prevention. The development of overweight and obesity depends not only on genetic components but also on lifestyle. The objective of the survey was to study the lifestyle of 15- to 19-year-old secondary school students in Budapest. METHODS Students (n = 1,273, 670 boys, 603 girls) were asked to complete questionnaires about their leisure activities, physical exercise, eating habits and knowledge of nutrition. The response rate was 45.2%. RESULTS Three-quarters of the secondary school students lived a sedentary life and more than half were dissatisfied with their body weight. More than 40% of the girls had been on a slimming diet at least once. Half of the students regularly consumed vitamin and/or mineral supplements. Nearly 25% of the adolescents did not have breakfast and nearly 60% of the school-leavers smoked regularly. CONCLUSIONS Coordinated cooperation is necessary among stakeholders to support the aim of changing nutritional and exercise behavior of adolescents.

Abstract
The influences of gender and physical activity on the development of fitness are reviewed from early childhood to late adolescence. Changes in parameters of fitness prior to puberty are driven predominantly by neuroendocrine-mediated factors, although physical activity level may be influenced largely by sociocultural factors prior to and following puberty. Thus, it is still unclear to what extent environment versus genetics accounts for gender differences in fitness. Future studies need to account for all factors known to explain gender differences in fitness to better differentiate intrinsic versus environmental causes. Consequently, one must consider if and to what extent a gender comparison study actually reveals true, inherent gender differences compared with sociocultural and/or cultural influences. Nevertheless, differences in fitness between girls and boys that are influenced by sociocultural factors should be considered when devising programs to promote physical activity and enhance fitness in youth. Fundamentally, the role of parents and primary caregivers in modeling physical activity and influencing the fitness level of their child cannot be overestimated.

Abstract
The pathological processes associated with development of cardiovascular disease begin early in life. For example, elevated blood pressure (BP) can be seen in childhood and tracks into adulthood. The relationship between physical activity (PA) and BP in adults is well-established, but findings in children have been inconsistent, with few studies measuring PA mechanically. Children aged 11 to 12 years were recruited from the Avon Longitudinal Study of Parents and Children. 5505 had systolic and diastolic BP measurements, plus valid (at least 10 hours for at least 3 days) accelerometer measures of PA; total PA recorded as average counts per minute (cpm) over the period of valid recording, and minutes per day spent in moderate to vigorous PA (MVPA). Data on a number of possible confounders were also available. Small inverse associations were observed; for systolic BP, β=−0.44 (95% confidence interval −0.59, −0.28) mm Hg per 100 cpm, and β=−0.66 (95% CI −0.92, −0.39) mm Hg per 15 minutes/d MVPA, adjusting for child’s age and gender. After adjustment for potential confounders, associations were weakened but remained. When PA variables were modeled together, associations with total PA were only a little weaker, whereas those with MVPA were substantially reduced; for systolic BP, β=−0.42 (95% CI −0.71, −0.13) mm Hg per 100 cpm, and β=−0.03 (95% CI −0.54, 0.48) mm Hg per 15 minutes/d MVPA. In conclusion, higher levels of PA were associated with lower BP, and results suggested that the volume of activity may be more important than the intensity.

Abstract
OBJECTIVE To record the prevalence of overweight, obesity and hypertension in primary schoolchildren living in one of the poorest regions in Europe and furthermore to identify certain behavioural, lifestyle and physiological parameters associated with body mass index (BMI) and blood pressure (BP). DESIGN Cross-sectional study. SETTING Nineteen primary schools within the county of Ioannina, Greece. SUBJECTS AND METHODS Demographic, dietary and physical activity data as well as anthropometrical, BP and cardiorespiratory fitness measurements were obtained from a representative sample of 312 school children (153 boys and 159 girls) attending 5th grade. Inclusion of subjects in the study was voluntary. One-way analysis of variance and multiple linear regression analysis were mainly applied for the evaluation of the tested hypotheses. RESULTS The prevalence of overweight and obesity was 29.4 and 11.8% for boys and 39.0 and 7.5% for girls. The prevalence of systolic and diastolic hypertension was 28.1 and 7.8% for boys and 26.4 and 17.0% for girls. Furthermore, BMI and BP (systolic and diastolic) were positively related to frequency of fast food meals (rho: + 0.28, P = 0.033, rho: + 1.09, P = 0.03 and rho: +0.86, P = 0.014, respectively) but negatively to leisure time physical activity (rho: -5.55, P = 0.005, rho: -3.32 x 10(-2), P < 0.001 and rho: -2.08 x 10(-2), P < 0.001, respectively). CONCLUSIONS The current study revealed an increased prevalence of overweight, obesity and hypertension among schoolchildren in Ioannina, indicating the need for early preventive measures in one of the less privileged regions of Europe.

Abstract
BACKGROUND Overweight prevalence among children/adolescents is increasing, while adult obesity may potentially cause a decline in life expectancy. More exercise is uniformly recommended, although treatment efficacy remains unclear. OBJECTIVE To determine the efficacy of exercise alone for treating overweight in children/adolescents. DESIGN A systematic review and meta-analysis of randomized trials published in English were completed following multiple database searches performed on December 10, 2004. Studies of isolated or adjunctive exercise/physical activity treatment in overweight/obese children or adolescents which reported any overweight outcome were included. Literature searches identified 645 papers which were manually searched, of which 45 were considered for inclusion, of which 13 papers which reported 14 studies were included (N=481 overweight boys and girls, aged approximately 12 years). Two reviewers independently identified relevant papers for potential inclusion and assessed methodological quality. Principal measures of effects included the mean difference (MD) (between treatment and control groups), the weighted MD (WMD), and the standardized MD (SMD). RESULTS Few studies were of robust design. The pooled SMD was -0.4 (-0.7, -0.1, P=0.006) for percent body fat, and -0.2 (-0.6, 0.1, P=0.07) for central obesity outcomes, whereas the pooled WMD was -2.7 kg (-6.1 kg, 0.8 kg, P=0.07) for body weight, all of which favored exercise. Pooled effects on body weight were significant and larger for studies of higher doses, whereas nonsignificant and smaller effects were seen for studies of lower doses of exercise (155-180 min/weeks vs 120-150 min/weeks). CONCLUSIONS Based on the small number of short-term randomized trials currently available, an aerobic exercise prescription of 155-180 min/weeks at moderate-to-high intensity is effective for reducing body fat in overweight children/adolescents, but effects on body weight and central obesity are inconclusive. Recommendations for future study designs are discussed.

Abstract
OBJECTIVE The prevalence of childhood obesity has been rising during the past decades in many parts of the world, including Greece. The dispersion of these trends across age, however, is less clear. The aim of this study was to examine the relationship between age and 20-year changes in anthropometric characteristics of Greek boys. RESEARCH METHODS AND PROCEDURES A total of 204 and 106 boys 9 years old, 163 and 274 boys 12 years old, and 161 and 240 boys 15 years old were randomly recruited in 1982 and 2002, respectively, throughout the county of Iraklio, Crete, Greece. Height, weight, and BMI were measured. RESULTS Contemporary 9 and 12 year olds were taller than their peers in 1982 (+2.9% and +1.2%, respectively; p < 0.005), but this was not the case for 15 year olds (-0.8%; p = 0.083). Body weight and BMI were higher now than in the 1980s, and this held true for all age groups (p < 0.001). Increases in weight also showed a decline with advancing age (+17.4%, +13.9%, and +4.0% for 9, 12, and 15 year olds, respectively), whereas BMI changes were similar for those 9 and 12 years of age (approximately 10.5%), but were almost 2-fold higher than in 15 year olds (+5.5%). DISCUSSION Contemporary boys are taller, heavier, and have higher BMI values than their peers in 1982, but the magnitude of these increases gradually declines with advancing age. Rates of increase in BMI, however, seem to have greatly accelerated compared with previous decades.

Abstract
PURPOSE Obesity has an etiology that is multidimensional in nature. Given the dearth of longitudinal data, we examined changes in adipose tissue (Ad) in relation to physical activity levels (PA), aerobic fitness (AF), and energy intake (EI) in Greek schoolchildren, as they progressed from age 12 to 14 yr. METHODS This was a 2-yr and three-time-point (TP) study. Participants (N=210 (TP1); =204 (TP2); =198 (TP3)) were assessed for anthropometry, maturity status, Ad, PA, AF, and EI. Mean values were used for exploratory analyses, whereas two generalized estimating equations (GEE) models examined for longitudinal associations between the studied parameters. The first (GEE1) aimed to extract inherent associations between the dependent (Ad) and independent (PA, AF, EI) variables for the entire study period. For further evidence of association, the second analysis (GEE2) used the independent variables at TP1 and TP2 to predict the dependent variables at TP3. RESULTS Levels of Ad in boys decreased significantly (P<0.05) from TP1 to TP3, whereas the same variable demonstrated a nonsignificant increase (P>0.05) in girls. GEE1 revealed that longitudinal changes in Ad were significantly associated only with PA (beta=-0.16; P<0.001) and AF (beta=-0.09; P<0.05) for all schoolchildren. Similarly, GEE2 revealed that the main factors (at TP1 and TP2) predicting the development of Ad (at TP3) were PA (beta=-0.14; P<0.001) followed by AF (beta=-0.10; P<0.05). CONCLUSION With respect to data presented, we established that longitudinal changes in Ad are mainly accompanied by changes in PA and, to a lesser extent, AF levels.

Abstract
Two cases are described in which a peripherally inserted central catheter tip in the saphenous vein appeared to be in the inferior vena cava by an anteroposterior abdominal radiograph, but a lateral view revealed the catheter tip to be outside the inferior vena cava. The actual location of the catheter tip placement may be misleading with a single radiograph. Two-view radiographs should be considered to assure the proper catheter tip placement.

Abstract
OBJECTIVE The study objective was to obtain data on interpretation, including intra and interobserver variation and action taken for a given line tip location, for a series of radiographs demonstrating neonatal long lines. METHODS Nineteen radiographs taken to identify line tip position were digitized and published on an internet site. One film was included twice in order to assess intraobserver variation giving a total of 20 images. Fourteen used radio-opaque contrast and five no contrast. Australian and New Zealand Neonatal Network members and National Women's Hospital NICU staff were invited to participate in the study. For each radiograph, participants were asked to identify if long line tip could be identified, the likely anatomical position and desired action. Interobserver agreement was assessed by the maximum proportion of agreement per radiograph and by the number of different options selected. Intraobserver agreement was assessed by comparing the two reports from the duplicate radiograph. RESULTS Twenty-seven responses were received. Overall, 50% of the reports stated that the long line tips could be identified. The most commonly reported position was in the right atrium (31%) and most commonly reported action was to pull the line back (53%). The median agreement of whether the line was seen was 68%, agreement on position 62% and agreement on action 86%. On analysis of intraobserver variability, from the identical radiographs, 27% of respondents differed on whether the line tip could be visualized. CONCLUSION Interobserver and intraobserver reliability was poor when using radiographs to assess long line tips. The major determinant of line repositioning was the perceived location.
