The purpose of the study was to determine which gait variables derived from upper and lower trunk accelerometry are associated with the incidence of falls, and to compare the discriminative ability of gait variables and physical performance. Methods This study was a 1-year prospective study. Older people (n = 73 walked normally while wearing accelerometers attached to the upper and lower trunk. Participants were classified as fallers (n = 16 or non-fallers (n = 57 based on the incidence of falls over 1 year. The harmonic ratio (HR of the upper and lower trunk was measured. Physical performance was measured in five chair stands and in the timed up and go test. Results The HR of the upper and lower trunk were consistently lower in fallers than non-fallers (P P Conclusions HR derived from upper trunk accelerometry may predict the risk of falls, independently of physical performance. The discriminative ability of HR for the risk of falls may have some validity, and further studies are needed to confirm the clinical relevance of trunk HR.

  8. FDG PET during radiochemotherapy is predictive of outcome at 1 year in non-small-cell lung cancer patients: a prospective multicentre study (RTEP2)

    To assess prospectively the prognostic value of FDG PET/CT during curative-intent radiotherapy (RT) with or without concomitant chemotherapy in patients with non-small-cell lung cancer (NSCLC). Patients with histological proof of invasive localized NSCLC and evaluable tumour, and who were candidates for curative-intent radiochemotherapy (RCT) or RT were preincluded after providing written informed consent. Definitive inclusion was conditional upon significant FDG uptake before RT (PET1). All included patients had a FDG PET/CT scan during RT (PET2, mean dose 43 Gy) and were evaluated by FDG PET/CT at 3 months and 1 year after RT. The main endpoint was death (from whatever cause) or tumour progression at 1 year. Of 77 patients preincluded, 52 were evaluable. Among the evaluable patients, 77 % received RT with induction chemotherapy and 73 % RT with concomitant chemotherapy. At 1 year, 40 patients (77 %) had died or had tumour progression. No statistically significant association was found between stage (IIIB vs. other), histology (squamous cell carcinoma vs. other), induction or concomitant chemotherapy, and death/tumour progression at 1 year. The SUVmax in the PET2 scan was the single variable predictive of death or tumour progression at 1 year (odds ratio 1.97, 95 % CI 1.25 - 3.09, p = 0.003) in multivariate analysis. The area under the receiver operating characteristic curve was 0.85 (95 % CI 0.73 - 0.94, p -4). A SUVmax value of 5.3 in the PET2 scan yielded a sensitivity of 70 % and a specificity of 92 % for predicting tumour progression or death at 1 year. This prospective multicentre study demonstrated the prognostic value in terms of disease-free survival of SUVmax assessed during the 5th week of curative-intent RT or RCT in NSCLC patients (NCT01261598; RTEP2 study).

    2013-08-01

    Computed tomography (CT) was used to explore if changes in muscle cross-sectional area and quality after anterior cruciate ligament (ACL) injury and reconstruction would be related to knee function. Fourteen females and 23 males (16-54 years) underwent clinical tests, subjective questionnaires, and CT 1 week before and 1 year after ACL surgery with semitendinosus-gracilis (STG) graft and rehabilitation. Postoperatively, knee laxity was decreased and functional knee measures and subjective patient scores improved. The most obvious remaining deficit was the quadriceps atrophy, which was significantly larger if the right leg was injured. Right-leg injury also tended to cause larger compensatory hypertrophy of the combined knee flexor and tibial internal rotator muscles (preoperatively). The quadriceps atrophy was significantly correlated with the scores and functional tests, the latter also being related to the remaining size of the gracilis muscle. Biceps femoris hypertrophy and, in males only, semimembranosus hypertrophy was observed following the ACL reconstruction. The lack of semimembranosus hypertrophy in the women could, via tibial internal rotation torque deficit, contribute to the less favorable functional and subjective outcome recorded for the women. The results indicate that the quadriceps, the combined knee flexor/tibial internal rotator muscles, side of ACL injury, and sex are important to consider in rehabilitation after STG graft.

    Several procedures have been proposed to achieve maxillary ridge augmentation. These require bone replacement materials to be manually cut, shaped, and formed at the time of implantation, resulting in an expensive and time-consuming process. In the present study, we describe a technique for the design and fabrication of custom-made scaffolds for maxillary ridge augmentation, using three-dimensional computerized tomography (3D CT) and computer-aided design/computer-aided manufacturing (CAD/CAM). CT images of the atrophic maxillary ridge of 10 patients were acquired and modified into 3D reconstruction models. These models were transferred as stereolithographic files to a CAD program, where a virtual 3D reconstruction of the alveolar ridge was generated, producing anatomically shaped, custom-made scaffolds. CAM software generated a set of tool-paths for manufacture by a computer-numerical-control milling machine into the exact shape of the reconstruction, starting from porous hydroxyapatite blocks. The custom-made scaffolds were of satisfactory size, shape, and appearance; they matched the defect area, suited the surgeon's requirements, and were easily implanted during surgery. This helped reduce the time for surgery and contributed to the good healing of the defects. PMID:23343341

    Diabetes mellitus is a frequent comorbid conditions among patients with pneumonia living in the community.The aim of our study is to evaluate the impact of hospitalization for pneumonia on early (30 day) and late mortality (1 year) in patients with type 2 diabetes mellitus.Prospective comparative cohort study of 203 patients with type 2 diabetes hospitalized for pneumonia versus 206 patients with diabetes hospitalized for other noninfectious causes from January 2012 to December 2013 at Policlinico Umberto I (Rome). Enrolled patients were followed up to discharge and up to 1 year after initial hospital admission or death.Overall, 203 patients with type 2 diabetes admitted to hospital for pneumonia were compared to 206 patients with type 2 diabetes admitted for other causes (39.3% decompensated diabetes, 21.4% cerebrovascular diseases, 9.2% renal failure, 8.3% acute myocardial infarction, and 21.8% other causes). Compared to control patients, those admitted for pneumonia showed a higher 30-day (10.8% vs 1%, P malnutrition were more likely to present with a mental status deterioration, and had a higher number of cardiovascular events during the follow-up period. Cox regression analysis found age, Charlson comorbidity index, pH < 7.35 at admission, hemodialysis, and hospitalization for pneumonia as variables independently associated with mortality.Hospitalization for pneumonia is associated with decreased 1-year survival in patients with type 2 diabetes, and appears to be a major determinant of long-term outcome in these patients.

    Full Text Available Abstract Background Distal radius fracture is a common injury and may result in substantial dysfunction and pain. The purpose was to investigate the relationship between distal radius fracture malunion and arm-related disability. Methods The prospective population-based cohort study included 143 consecutive patients above 18 years with an acute distal radius fracture treated with closed reduction and either cast (55 patients or external and/or percutaneous pin fixation (88 patients. The patients were evaluated with the disabilities of the arm, shoulder and hand (DASH questionnaire at baseline (concerning disabilities before fracture and one year after fracture. The 1-year follow-up included the SF-12 health status questionnaire and clinical and radiographic examinations. Patients were classified into three hypothesized severity categories based on fracture malunion; no malunion, malunion involving either dorsal tilt (>10 degrees or ulnar variance (≥1 mm, and combined malunion involving both dorsal tilt and ulnar variance. Multivariate regression analyses were performed to determine the relationship between the 1-year DASH score and malunion and the relative risk (RR of obtaining DASH score ≥15 and the number needed to harm (NNH were calculated. Results The mean DASH score at one year after fracture was significantly higher by a minimum of 10 points with each malunion severity category. The RR for persistent disability was 2.5 if the fracture healed with malunion involving either dorsal tilt or ulnar variance and 3.7 if the fracture healed with combined malunion. The NNH was 2.5 (95% CI 1.8-5.4. Malunion had a statistically significant relationship with worse SF-12 score (physical health and grip strength. Conclusion Malunion after distal radius fracture was associated with higher arm-related disability regardless of age.

We enrolled 103 patients (median age: 61.6 years with 108 VCF due to trauma, or traumatic VCF with associated osteoporosis. Primary outcome was back pain intensity (VAS. Secondary outcomes were Oswestry Disability Index (ODI, EuroQol-VAS, and analgesic consumption. 48 hours after surgery, a median relative decrease in pain intensity of 81.5% was observed associated with a significant reduction in analgesic intake. Improvements in disability (91.3% decrease in ODI score and in quality of life (increase 21.1% of EQ-VAS score were obtained 3 months after surgery. All results were maintained at 12 months. A reduction in the kyphotic angulation was observed postoperatively (-5.4±6.3°; p<0.001, remained at 12 months (-4.4±6.0°, p=0.002. No adverse events were implant-related and none required device removal. Three patients (2.9% experienced procedure-related complications. The overall adjacent fracture rate up to 1 year after surgery was 2.9%. The SpineJack procedure is an effective, low-risk procedure for patients with traumatic VCF allowing a fast and sustained improvement in quality of life over 1 year after surgery.

    The results of previous cross-sectional studies suggest that free thyroxine (FT4) levels are associated with cognitive abilities (particularly attention/vigilance) during the early stages of psychosis. We aimed to explore whether hypothalamic-pituitary-thyroid hormones predict cognitive changes in a 1-year longitudinal study following first episodes of psychosis (FEP). We studied 36 FEP patients and a control group of 50 healthy subjects (HS). Plasma levels of thyroid-stimulating hormone (TSH) and FT4 were measured. Cognitive assessment was performed with the MATRICS Cognitive Consensus Cognitive Battery (MCCB). FEP patients were assessed twice (baseline and after 1year), whereas HS were assessed only once. We compared cognitive changes at 1year between three groups based on baseline FT4 levels: 1) lowest quartile (Q1, FT41.54ng/dL). No differences in TSH or FT4 levels were found between HS and FEP patients. All participants had FT4 levels within the normal range. HS outperformed FEP patients in all cognitive tasks. In relation to the relationship between FT4 levels and cognitive changes, a U-shaped pattern was observed: FEP patients from the middle quartiles (Q2-Q3) improved in attention/vigilance, whereas both extreme quartiles (Q1 and Q4) showed a worsening in this cognitive domain over time. Patients with lower FT4 (Q1) showed poorer baseline attention; therefore, lower baseline FT4 levels predicted a poorer prognosis in terms of attention performance. Our study suggests that baseline FT4 levels are associated with changes in attention and vigilance performance over one year in FEP patients. PMID:26805411

    The outcome of premature infants with only diffuse excessive high signal intensity (DEHSI) is not clear. We explored the relationship between DEHSI, white matter (WM) diffusion characteristics, perinatal characteristics, and neurobehavioral outcome at 1 year in a homogenous group of preterm infants without major brain abnormalities. Fifty-eight preterm infants, gestational age 29 ± 2.6 weeks, underwent an MRI at term-equivalent age (TEA). Griffiths Mental Developmental Scales, neurological assessment, and Parental Stress Index (PSI) were performed at 1 year corrected age. These measures were compared between preterm infants according to DEHSI classification (none, mild, moderate). Diffusion tensor imaging was used in major WM volumes of interest to objectively measure the degree of WM maturation. No significant differences were detected in the perinatal risk characteristics, neurobehavioral outcome, and PSI at 1 year between infants with different DEHSI classifications. In infants with DEHSI, increased axial and radial diffusivities were detected in the optic radiations, centrum semiovale, and posterior limb of the internal capsule, indicating less advanced maturation of the WM. Significant correlations were detected between the time interval from birth to MRI and the WM microstructure in infants without DEHSI. DEHSI in premature infants is neither a predictive measure for short-term adverse neurobehavioral outcome nor related to perinatal risk characteristics. Extrauterine exposure time had a differential effect on WM maturational trajectories in infants with DEHSI compared to those without. We suggest DEHSI may represent an alteration in WM maturational characteristics. Further follow-up studies may verify later consequences of DEHSI in premature infants. (orig.)

    Full Text Available Abstract Background Musculoskeletal pain symptoms are common in children and adolescents. These symptoms have a negative impact on children's physical and emotional well-being, but their underlying aetiology and risk factors are still poorly understood. Most of the previous cohort studies were conducted among mid and/or late adolescents and were mainly focused on a specific pain location (e.g. low back pain or neck pain. The purpose of this study is to estimate occurrence of new-onset pain symptoms, in all musculoskeletal locations, in preteens and early adolescents and investigate risk factors for development of these symptoms. Methods 1756 schoolchildren (mean age 10.8 were recruited from schools in southern Finland. Information was extracted as to whether they experienced musculoskeletal pain and a total of 1192 children were identified as free of musculoskeletal pain symptoms. Information was collected on factors which could potentially predict the development of musculoskeletal pain: headache, abdominal pain, sadness/feeling down, day-time tiredness, difficulty in falling asleep, waking up during nights, level of physical activity and hypermobility. These children were followed-up 1-year later and those with new episodes of non-traumatic and traumatic musculoskeletal pain symptoms were identified. Results A total of 1113 schoolchildren (93% of baseline pain-free children were found at one-year follow-up. New episodes of musculoskeletal pain were reported by 21.5% of these children. Of them 19.4% reported non-traumatic pain and 4.0% reported traumatic pain. The neck was the most commonly reported site with non-traumatic pain, while the lower limb was the most common site for traumatic pain. The independent risk factors for non-traumatic musculoskeletal pain were headache (OR = 1.68, [95% CI 1.16–2.44] and day-time tiredness (OR = 1.53, [95% CI 1.03–2.26]. The risk factors for traumatic musculoskeletal pain were vigorous exercise (OR = 3

DESIGN: Prospective cohort, non-interventional study. METHODS: 132 treatment-naïve patients who received treatment for AMD-CNV and PCV were included. All patients underwent standardized examination procedures including retinal imaging at baseline and follow-up. AMD-CNV and PCV were defined on fundus fluorescein angiography and indocyanine green angiography at baseline. Patients were treated according to standard of care.We report the visual acuity (VA and optical coherence tomography (OCT measurements at baseline, month 3 and month 12 The factors influencing month 12 outcomes were analyzed. MAIN OUTCOME MEASURE: Type of treatment, number of Anti-vascular endothelial growth factor (VEGF treatments, visual outcome over one year. RESULTS: Anti-VEGF monotherapy was the initial treatment in 89.1% of AMD-CNV, but only 15.1% of PCV. The mean number of anti-VEGF injections up to month 12 was 3.97 (4.51 AMD-CNV, 3.43 PCV, p = 0.021. Baseline OCT, month 3 OCT and month 3 VA were significant in determining continuation of treatment after month 3. At month 12, mean VA improved from 0.82 (∼20/132 at baseline to 0.68 (∼20/96 at month 12 (mean gain 6.5 ETDRS letters, p = 0.002. 34.2% of eyes (38/113 eyes gained ≥15 ETDRS letters and 14.4% (16/113 eyes lost ≥15 ETDRS letters.

  3. MVPA is associated with lower weight gain in 8-10 year old children: a prospective study with 1 year follow-up.

    Abigail Fisher

    Full Text Available BACKGROUND: Studies relating physical activity (PA to weight gain in children have produced mixed results, although there is some evidence for stronger associations with more intense physical activities. The present study tested the hypothesis that weight gain over one year in 8-10 year olds would be more strongly predicted by moderate and vigorous physical activity (MVPA than total physical activity (total PA or sedentary behaviour. METHODOLOGY: Participants were 280 children taking part in the Physical Exercise and Appetite in Children Study (PEACHES. Weight status was assessed using body mass index (BMI, fat mass index (FMI, and waist circumference (WC in school Year 4 (baseline; age 8.7 yrs and Year 5 (follow-up; age 9.7 yrs. Physical activity was measured at baseline using the Actigraph GT1M accelerometer to assess total PA (mean accelerometers counts per minute, MVPA; ≥ 4000 counts per minute and sedentary time (<100 counts per minute. PRINCIPAL FINDINGS: After adjustment for baseline BMI, SES, sex and ethnicity, MVPA was significantly associated with follow-up BMI (adjusted β  = -0.07; p = 0.002. This association was independent of total PA or sedentary time. Similar results were observed for FMI; again MVPA was significantly associated with follow up FMI (β = -0.16; p = 0.001 independent of total PA or sedentary time. The pattern was similar for WC (β = -0.07, but the association between MVPA and WC did not reach significance at p = 0.06. CONCLUSION: The results of this study strongly support promotion of MVPA in children.

    Objective To explore the baseline predictors of clinical effectiveness after tocilizumab or infliximab treatment in biologic-naïve rheumatoid arthritis patients. Methods Consecutive biologic-naïve patients with rheumatoid arthritis initiating infliximab (n = 57) or tocilizumab (n = 70) treatment were included in our prospective cohort study. Our cohort started in February 2010, and the patients observed for at least 1 year as of April 2013 were analysed. We assessed baseline variables including patients' characteristics (age, sex, disease duration, prednisolone dose, methotrexate dose, other disease-modifying antirheumatic drug use, Clinical Disease Activity Index [CDAI]) and serum biomarker levels (C-reactive protein, immunoglobulin M-rheumatoid factor, anti-cyclic citrullinated protein/peptide antibodies, interferon-γ, interleukin (IL)-1β, IL-2, IL-6, IL-8, IL-10, IL-17, tumor necrosis factor-α, soluble intercellular adhesion molecule-1, bone alkaline phosphatase, osteonectin, osteopontin) to extract factors associated with clinical remission (CDAI≤2.8) at 1 year using univariate analyses, and the extracted factors were entered into a multivariate logistic regression model. Similar analyses were also performed for Simplified Disease Activity Index (SDAI) remission (≤3.3) and Disease Activity Score with 28 joint counts, erythrocyte sedimentation rate (DAS28-ESR) remission (<2.6). Results There were no significant differences in the baseline characteristics except for methotrexate use between the groups. In the multivariate analyses, the low baseline osteopontin levels (OR 0.9145, 95% CI 0.8399–0.9857) were identified as predictors of CDAI remission in the tocilizumab group, whereas no predictors of CDAI remission were found in the infliximab group. Similar results were obtained when using SDAI and DAS28-ESR remission criteria. Conclusion Baseline low serum osteopontin levels predict clinical remission 1 year after tocilizumab treatment and not

  8. Vertebroplasty and kyphoplasty in osteoporotic fractures of vertebral bodies - a prospective 1-year follow-up analysis

    Purpose: Kyphoplasty and vertebroplasty offer two minimally invasive operative stabilization procedures for vertebral compression fractures. The purpose of this prospective study was to investigate whether both procedures are able to reduce pain and to preserve postoperative vertebral height during a 1-year follow up. Materials and methods: Osteoporotic vertebral fractures were treated in 42 cases, 20 patients (15 female, 5 male) underwent vertebroplasty, 22 patients (14 female, 8 male) underwent kyphoplasty. 32 vertebral fractures were treated with vertebroplasty and 35 vertebral fractures were treated with kyphoplasty. Symptomatic levels were identified by correlating the clinical presentation with conventional radiographs, CT or/and MRI. During the follow up reduction of pain was determined. Radiographic scans were performed pre- and postoperatively and after 3, 6 and 12 months. The vertebral height and endplate angles were measured to assess the restoration of the sagittal alignment. The effects on pain symptoms were measured on a self-reported Visual Analog Scale (VAS) and the Oswestry score was documented. Results: The median pain scores (VAS) decreased significantly for kyphoplasty and vertebroplasty from pre- to post-treatment, as did the Oswestry score (p<0.05). No significant differences could be found between both groups for the median pain score (VAS) and the Oswestry score. Kyphoplasty led to a significant restoration of the vertebral height and reduction of kyphosis (p<0.05). During the 1-year follow up operation techniques were able to stabilize the height of the vertebral body. Conclusion: Kyphoplasty and vertebroplasty are effective minimally invasive procedures for the stabilization of osteoporotic vertebral fractures leading to a statistically significant reduction in pain. Kyphoplasty restores significantly vertebral body height in fresh fractures. The restoration of vertebral height and reduction of kyphosis may have an influence on the long

    Standard guidelines for ongoing management, as well as definitive data about the long-term course of idiopathic intracranial hypertension (IIH) are not available. The aim of this study was to compare several clinical and instrumental variables as assessed at the time of diagnosis and then after 1 year in a sample of IIH patients. A total of 21 patients were studied. Our results confirmed that headache and TVO are the most frequent symptoms in IIH patients, and that overweight is a very common feature. A trend towards a favorable outcome in patients followed for 1 year and treated by usual medical therapy was found: intracranial pressure was lower at follow-up; improvement of headache and transient visual obscurations, as well as of papilledema, was reported in most patients. On the other hand, neuroradiological findings (such as empty sella, perioptic subarachnoid space distension, narrowing of the transverse sinuses) were substantially stable at follow. These findings may be relevant for future research as far as understanding the role of different clinical and instrumental findings as diagnostic items as well as predictors of outcome in IIH.

  10. Poststroke depression and risk of recurrent stroke at 1 year in a Chinese cohort study.

    Huai Wu Yuan

    Full Text Available BACKGROUND: Studies show that poststroke depression (PSD increases mortality risk at 1 year. However, whether PSD increases the risk of recurrent stroke at 1 year remains unclear. This study was to investigate whether PSD at 2 weeks following a stroke could increase risk of recurrent stroke at 1 year. METHODS AND RESULTS: This was a multi-centered prospective cohort study. A total of 2306 patients with acute stroke were enrolled in our study. PSD was diagnosed according to the criteria set by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV. The outcomes of recurrent stroke were followed up via face-to-face or phone interview. A total of 1713 patients had complete follow-up data, with 481 (28.1% cases of PSD and 158 (9.2% cases of cumulative recurrent stroke at 1 year. Multivariate logistic regression analysis showed a 49% increase of OR of recurrent stroke at 1 year in patients with PSD, compared to patients without PSD following a stroke (OR=1.49, 95%CI: 1.03-2.15. There was no significant correlation between anti-depressant drugs and the risk of recurrent stroke at 1 year following a stroke (OR=1.96, 95%: CI 0.95-4.04. CONCLUSIONS: Based on the DSM-IV diagnostic criteria, nearly 3 out of 10 hospitalized stroke patients in China were diagnosed with PSD at 2 weeks following a stroke. PSD is associated with a higher risk of recurrent stroke at 1 year. Our study did not find benefit of anti-depressant drugs in reducing such risk.

    The prospective 1-year EPIC study enrolled 341 patients with myelodysplastic syndromes (MDS); although baseline iron burden was >2500ng/mL, approximately 50% were chelation-naïve. Overall median serum ferritin decreased significantly at 1 year (p=0.002). Decreases occurred irrespective of whether patients were chelation-naïve or previously chelated; changes were dependent on dose adjustments and ongoing iron intake. Sustained reductions in labile plasma iron were observed. Discontinuation rate (48.7%) and adverse event profile were consistent with previously reported deferasirox data in MDS. Alanine aminotransferase levels decreased significantly; change correlated significantly with reduction in serum ferritin (p<0.0001). This large dataset prospectively confirms the efficacy and well characterizes the safety profile of deferasirox in MDS. PMID:20451251

  14. A longitudinal study of back dimension changes over 1 year in sports horses.

    Greve, Line; Dyson, Sue

    2015-01-01

    Major back dimension changes over time have been observed in some horses, the speed of which may be influenced by work type, skeletal maturity, nutrition and saddle fit. Currently, there are no longitudinal data quantifying changes in back dimensions. The objectives of this study were to quantify back dimension changes over time, to identify the effects of horse, saddle and rider on these dimensions, and to determine their association with season, weight, work and saddle management. A prospective, longitudinal study was performed, using stratified random sampling within a convenience sample of 104 sports horses in normal work. Thoracolumbar dimensions/symmetry were measured at predetermined sites every second month over 1 year; weight, work and saddle management changes were recorded. Descriptive statistics, and univariable and multiple mixed effects linear regression were performed to assess the association between management changes, horse-saddle-rider factors and back dimension changes. Complete data was available for 63/104 horses, including horses used for dressage (n= 26), showjumping (n= 26), eventing (n= 26) and general purpose (n= 26), with age groups 3-5 years (n = 24), 6-8 years (n = 28), 9-12 years (n = 24) and ≥ 13 years (n = 28). There were considerable variations in back dimensions over 1 year. In the multivariable analysis, the presence of gait abnormalities at initial examination and back asymmetry were significant and had a negative effect on changes in back dimensions. Subsequent improved saddle fit, similar or increased work intensity, season (summer versus winter) and increased bodyweight retained significance, having positive effects on changes in back dimensions. In conclusion, quantifiable changes in back dimensions occur throughout the year. Saddle fit should be reassessed professionally several times a year, especially if there has been a change in work intensity. PMID:25510314

    2016-02-01

    Non-overweight individuals may follow aggressive weight management approaches alongside overweight/obese friends or family members; thus, research has begun to evaluate subsequent effects among non-overweight populations. A prior study evaluated the short-term effects of an immersion weight loss programme on healthy young adult staff leaders. Results indicated that participation seemed to benefit, not harm, the young adults. The current investigation examined 1-year eating disorder and weight trajectories in this sample. The total sample (N = 244) consisted of staff leaders (44.3%) and demographically similar comparison participants who completed eating disorder and weight assessments across four time points: baseline, end of summer, 6-week follow-up and 1-year follow-up. Forty-seven per cent of the original sample responded to all time points (staff leaders n = 60; comparison n = 55). Over the course of 1 year, risk trajectories did not differ between groups. Staff leaders did not report significant changes in body mass index, suggesting that they maintained healthy weight over the course of 1 year. Participation as an immersion weight loss programme leader appeared to be protective against weight gain, without increasing eating disorder risk, for healthy young adults. This provides further support for using weight management interventions across a wide range of individuals. PMID:26638779

  18. Neuropsychological outcome after fractionated stereotactic radiotherapy (FSRT) for base of skull meningiomas: a prospective 1-year follow-up

    Purpose: The purpose of this study was to evaluate the cognitive outcome after fractionated stereotactic radiotherapy (FSRT) in patients with base of skull meningiomas. Methods and material: A total of 40 patients with base of skull meningiomas were neuro psychologically evaluated before, after the first fraction (1.8 Gy), at the end of FSRT (n=37), 6 weeks (n=24), 6 (n=18) and 12 months (n=14) after FSRT. A comprehensive test battery including assessment of general intelligence, attention and memory functions was used. Alternate forms were used and current mood state was controlled. Results: After the first fraction a transient decline in memory function and simultaneous improvements in attention functions were observed. No cognitive deteriorations were seen during further follow-up, but increases in attention and memory functions were observed. Mood state improved after the first fraction, at the end of radiotherapy and 6 weeks after radiotherapy. Conclusion: The present data support the conclusion that the probability for the development of permanent cognitive dysfunctions appears to be very low after FSRT. The transient memory impairments on day 1 are interpreted as most likely related to an increase of a preexisting peritumoral edema, whereas the significant acute improvements in attention functions are interpreted as practice effects. An analysis of localization specific effects of radiation failed to show clear hemisphere specific cognitive changes

    2016-01-01

    Enteroaggregative Escherichia coli (EAEC) has been associated with persistent diarrhea, reduced growth acceleration, and failure to thrive in children living in developing countries and with childhood diarrhea in general in industrialized countries. The clinical implications of an EAEC carrier-status in children in industrialized countries warrants clarification. To investigate the pathological significance of an EAEC carrier-state in the industrialized countries, we designed a 1-year dynamic cohort study and performed follow-up every second month, where the study participants submitted a stool sample and answered a questionnaire regarding gastrointestinal symptoms and exposures. Exposures included foreign travel, consumption of antibiotics, and contact with a diseased animal. In the capital area of Denmark, a total of 179 children aged 0–6 years were followed in a cohort study, in the period between 2009 and 2013. This is the first investigation of the incidence and pathological significance of EAEC in Danish children attending daycare facilities. Conventional microbiological detection of enteric pathogens was performed at Statens Serum Institute, Copenhagen, Denmark, and at Hvidovre Hospital, Copenhagen, Denmark. Parents completed questionnaires regarding gastrointestinal symptoms. The EAEC strains were further characterized by serotyping, phylogenetic analysis, and susceptibility testing. EAEC was detected in 25 (14%) of the children during the observational period of 1 year. One or more gastrointestinal symptoms were reported from 56% of the EAEC-positive children. Diarrhea was reported in six (24%) of the EAEC positive children, but no cases of weight loss, and general failure to thrive were observed. The EAEC strains detected comprised a large number of different serotypes, confirming the genetic heterogeneity of this pathotype. EAEC was highly prevalent (n = 25, 14%) in Danish children in daycare centers and was accompanied by gastrointestinal symptoms in

    2014-03-01

    The incidence of whooping cough in Romania is substantially underestimated, and, as noted by the health authorities, this is mostly due to the lack of both awareness and biological diagnosis. We conducted a 1-year study in Bucharest in order to assess the circulation of Bordetella pertussis, the main etiological agent of whooping cough. Fifty-one subjects suspected of whooping cough were enrolled. Culture, real-time PCR, and enzyme-linked immunosorbent assay were used for laboratory diagnosis. Whooping cough patients (63%) were distributed among all age groups, and most were unvaccinated, incompletely vaccinated, or had been vaccinated more than 5 years previously. Bordetella holmesii DNA was detected in 22% of the bordetellosis cases; these patients included adults; teenagers; and, surprisingly, young children. B. pertussis isolates were similar to the clinical isolates currently circulating elsewhere in Europe. One isolate does not express pertactin, an antigen included in some acellular pertussis vaccines. PMID:24355701

This study identified characteristics that differentiate patients with schizophrenia who are treated with olanzapine monotherapy versus polypharmacy in usual care in Japan.Patients and methods: In a large (N = 1850 prospective, observational study, Japanese patients with schizophrenia who initiated treatment with olanzapine were followed for 1 year. Consistent with past research, antipsychotic polypharmacy was defined as the concurrent use of olanzapine and another antipsychotic for at least 60 days. Switching was defined as discontinuing a prior antipsychotic therapy rather than augmenting the medication regimen. Predictors of antipsychotic monotherapy were based on information available at the time of olanzapine initiation. Baseline characteristics were compared using t-tests and Χ2 tests. Stepwise logistic regression was used to identify independent predictors of monotherapy.Results: Patients treated with olanzapine monotherapy (43.2% differed from those treated with antipsychotic polypharmacy (56.8% on demographics, treatment history, baseline symptom levels, functional levels, and treatment-emergent adverse events. Stepwise logistic regression identified multiple variables that significantly predicted monotherapy: older age, shorter duration of schizophrenia, outpatient status, comorbid medical conditions, lower body mass index, no prior anticholinergic use, no prior mood stabilizer use, and switching from a previous antipsychotic (typical or atypical

  4. Biochemical criteria at 1 year are not robust indicators of response to ursodeoxycholic acid in early primary biliary cirrhosis: results from a 29-year cohort study

    2013-01-01

    Background: In primary biliary cirrhosis (PBC), biochemical criteria at 1 year are considered surrogates of response to ursodeoxycholic acid (UDCA). However, due to the slow natural history of PBC, evaluation at 1 year may be suboptimal to assess the therapeutic response, particularly in early disease. Aim: To determine whether evaluation of biochemical criteria at 1 year is a reliable surrogate of UDCA response in early PBC. Methods: We analysed the prospectively collected data of 21...

    Lattice and Avellino's dystrophies among dystrophies and Salzmann's nodular degeneration showed specific stromal deposits making them easily diagnosable at histopathology, whereas the rest showed non-specific stromal changes mandating correlation with clinical findings. Seven regraft corneas showed stromal fibrosis making identification of primary dystrophy impossible. However, transmural vascularization and lymphocytic stromal infiltrate were prominently noted in failed grafts though their numbers were few. Conclusion: This histopathologic study characterizes classic features of macular, Avellino's, lattice corneal dystrophies and Salzmann's degeneration for their microscopic diagnosis, while the rest showed non-specific changes. Stromal edema was prominently noted in degenerations than in dystrophies. Degree of stromal vascularization and type of cellular infiltrate need attention in regrafts.

    Full Text Available Abstract Background Sickness absence increases with lower socioeconomic status. However, it is not well known how this relation depends on specific aspects of sickness absence or the degree to which socioeconomic differences in sickness absence may be explained by other factors. The purpose of the study was to examine differences in sickness absence among occupational groups in a large general hospital; how they depend on combinations of frequency and duration of sickness absence spells; and if they could be explained by self-reported general health, personal factors and work factors. Methods The design is a 1-year prospective cohort study of 2331 hospital employees. Baseline information include job title, work unit, perceived general health, work factors and personal factors recorded from hospital administrative files or by questionnaire (response rate 84%. Sickness absence during follow-up was divided into short (1-3 days, medium (4-14 days and long (>14 days spells, and into no absence, "normal" absence (1-3 absences of certain durations and "abnormal" absence (any other absence than "normal". Socioeconomic status was assessed by job titles grouped in six occupational groups by level of education (from doctors to cleaners/porters. Effects of occupational group on sickness absence were adjusted for significant effects of age, gender, general health, personal factors and work factors. We used Poisson or logistic regression analysis to estimate the effects of model covariates (rate ratios (RR or odds ratios (OR and their 95% confidence intervals (CI. Results With a few exceptions sickness absence increased with decreasing socioeconomic status. However, the social gradient was quite different for different types of sickness absence. The gradient was strong for medium spells and "abnormal" absence, and weak for all spells, short spells, long spells and "normal" absence. For cleaners compared to doctors the adjusted risk estimates increased 4.2 (95

  13. Video game addiction and college performance among males: results from a 1 year longitudinal study.

    Schmitt, Zachary L; Livingston, Michael G

    2015-01-01

    This study explored the pattern of video game usage and video game addiction among male college students and examined how video game addiction was related to expectations of college engagement, college grade point average (GPA), and on-campus drug and alcohol violations. Participants were 477 male, first year students at a liberal arts college. In the week before the start of classes, participants were given two surveys: one of expected college engagement, and the second of video game usage, including a measure of video game addiction. Results suggested that video game addiction is (a) negatively correlated with expected college engagement, (b) negatively correlated with college GPA, even when controlling for high school GPA, and (c) negatively correlated with drug and alcohol violations that occurred during the first year in college. Results are discussed in terms of implications for male students' engagement and success in college, and in terms of the construct validity of video game addiction. PMID:25584728

    2007-01-01

    Background To increase the number of clinician scientists and to improve research skills, a number of clinical research training programs have been recently established. However, controlled studies assessing their effectiveness are lacking. Objective To investigate the effectiveness of a 1-year resident training program in clinical research. Design Controlled before-and-after study. The training program included a weekly class in clinical research methods, completion of a research project, and mentorship. Participants Intervention subjects were 15 residents participating in the 1-year training program in clinical research. Control subjects were 22 residents not participating in the training program. Measurements and Main Results Assessments were performed at the beginning and end of the program. Outcomes included methodological research knowledge (multiple-choice progress test), self-assessed research competence, progress on publications and grant applications, and evaluation of the program using quantitative and qualitative methods. Results Intervention subjects and controls were well matched with respect to research experience (5.1 ± 2.2 vs 5.6 ± 5.8 years; p = .69). Methodological knowledge improved significantly more in the intervention group compared to the control group (effect size = 2.5; p < .001). Similarly, self-assessed research competence increased significantly more in the intervention group (effect size = 1.1; p = .01). At the end of the program, significantly more intervention subjects compared to controls were currently writing journal articles (87% vs 36%; p = .003). The intervention subjects evaluated the training program as highly valuable for becoming independent researchers. Conclusions A 1-year training program in clinical research can substantially increase research knowledge and productivity. The program design makes it feasible to implement in other academic settings. PMID:17922168

    There are no clearly defined guidelines for when an open or closed treatment is indicated for treatment of mandibular condylar fractures. The aim of the study is to analyze the mandibular function after nonsurgical treatment of unilateral subcondylar fractures, in a prospective study. A prospective study was conducted on 30 patients with unilateral mandibular subcondylar fracture undergoing nonsurgical treatment. Clinical and radiographic examinations were done prior to treatment and at 12-month follow-up. Pain, perceived occlusion, mouth opening, protrusion, and horizontal movements of the mandible were evaluated by clinical examination. Radiologic evaluation was done using Panoramic and Reverse Towne's radiographs. At 12-month follow-up, there was minimal pain in the temporomandibular joint region, there was an improvement in the perceived occlusion, and mouth opening did not reduce. There was insignificant absolute difference between left and right lateral mandibular movements. The amount of increase in the protrusion of mandible was insignificant. On radiographic evaluation, the degree of coronal and sagittal displacement was insignificant at follow-up. Mean ramus height pretreatment and 12 months posttreatment were 0.98 ± 0.50 and 0.87 ± 0.47, respectively. Based on this study, patients had adequate mandibular function and minimal pain after nonsurgical treatment. Unilateral subcondylar fractures of the mandible can be treated nonsurgically in patients with minimal occlusal discrepancies, adequate mouth opening, minimal displacement of condyle, and minimal ramus height shortening.

    Apathy, described as impaired motivation and goal-directed behavior, is a common yet often overlooked multidimensional psychopathological state in schizophrenia. Its underlying cognitive processes remain largely unexplored. Data was drawn from a longitudinal hospital study of patients with a DSM-IV diagnosis of schizophrenia; 137 (82.5%) participated at the 1-month follow-up and 81 (59.1%) at the 1-year follow-up. Apathy was assessed with the Lille Apathy Rating Scale, validated in French and in schizophrenia. Severe apathy, overall (total score > -13) and on 4 previously identified distinct dimensions, was considered. Episodic verbal learning was assessed with the California Verbal Learning Test, executive functioning with the Trail Making Test, the Six Element Test and the Stop Signal Paradigm and working memory with the Letter-Number Sequencing Test. After controlling for confounding variables, only episodic verbal learning was associated with severe overall apathy in the cross-sectional study. At 1 year, working memory was associated with an increased risk of severe overall apathy, adjusting for baseline apathy. Using a dimensional approach to apathy, specific types of cognition were found to be associated with specific dimensions of apathy. Our findings confirm the need for a multidimensional approach of negative symptoms in schizophrenia. Moreover, cognitive functioning could be a risk factor for developing severe apathy. Cognitive remediation may thus be a useful non-pharmacological intervention for treating apathy in schizophrenia patients. PMID:26834026

  1. Neurocutaneous syndrome: A prospective study

    Radheshyam Purkait

    2011-01-01

    Full Text Available Background: Neurocutaneous syndromes (NCS are a group of genetic disorders that produce a variety of developmental abnormalities of the skin along with an increased risk of neurological complications. Cutaneous manifestations usually appear early in life and progress with time, but neurological features generally present at a later age. There is a paucity of data regarding the evolution of skin lesions and their correlation with the central nervous system involvement in children. Aim: The primary objective was to track the course of skin lesions in various forms of NCS in the pediatric age group. Our secondary aim was to assess whether there was any predictive value of the lesions in relation to the neurological manifestations. Materials and Methods: This prospective longitudinal study was conducted at a tertiary care pediatric dermatology referral clinic of the Institute of Child Health, Kolkata, West Bengal. Children between the age group 0 and 12 years were included in the study on the basis of standard diagnostic criteria for different NCS, during the period from March, 2000 to February, 2004, and each of the enrolled cases were followed up for a duration of six years. Results: The study population comprised of 67 children (35 boys, 32 girls.The mean age of presentation was 33.8±27.8 months (range 10 days to 111 months. The various forms of NCS observed was neurofibromatosis 1(NF1 (n=33, tuberous sclerosis complex (TSC (n=23, Sturge Weber syndrome (n=6, ataxia telangiectasia (n=2, PHACE syndrome (n=1, incontinentia pigmenti (n=1, and hypomelanosis of Ito (n=1. The presentations were varied, ranging from predominantly cutaneous to primarily neurological, depending on the disease entity and age group concerned. There was a significant increase in the number of café au lait macules (CALMs with time (P=0.0002 in NF1, unlike that of hypopigmented macules of TSC (P=0.15. Statistically, no relation was documented between the evolution of skin

    Purpose To determine whether the brain functional abnormalities of drug-naive first-episode schizophrenia are reduced after 1 year of undergoing antipsychotic treatment and whether pretreatment resting-state functional magnetic resonance (MR) imaging parameters are associated with longitudinal changes in clinical symptoms. Materials and Methods This prospective study was approved by the local ethical committee, and written informed consent was obtained from all participants. Twenty antipsychotic-naive first-episode patients with schizophrenia and 16 healthy individuals were recruited and underwent resting-state functional MR imaging at baseline and again at 1-year follow-up, by which time significant clinical improvement was seen. The amplitude of low-frequency fluctuation (ALFF) and seed-based functional connectivity (FC) were analyzed with analysis of covariance. Results The amount of ALFF in the right inferior parietal lobule (IPL) and orbitofrontal cortex (OFC) and the amount of FC between the bilateral IPLs significantly increased over the follow-up period, and the amount of ALFF in the right occipital gyrus was reduced (P < .050, AlphaSim corrected [ http://afni.nimh.nih.gov/pub/dist/doc/manual/AlphaSim.pdf ]), returning toward normal levels. Furthermore, the degree of alteration in ALFF values in the right OFC (P = .037) and occipital gyrus (P = .002) at baseline was significantly correlated with the magnitude of the normalization in those regions at 1-year follow-up. In contrast, abnormalities of ALFF in the bilateral thalamus, ventral medial prefrontal cortex, precuneus, and right amygdala and of FC between the right OFC and the dorsal medial prefrontal cortex at baseline did not improve in patients at 1-year follow-up. Conclusion These findings show that some, but not all, neurophysiologic alterations that occur during the acute phase of schizophrenia are normalized in the context of clinical improvement and suggest therapeutic implications for

    2014-01-01

    This exploratory phase II study evaluated the safety and efficacy of belatacept in de novo adult liver transplant recipients. Patients were randomized (N = 260) to one of the following immunosuppressive regimens: (i) basiliximab + belatacept high dose [HD] + mycophenolate mofetil (MMF), (ii) belatacept HD + MMF, (iii) belatacept low dose [LD] + MMF, (iv) tacrolimus + MMF, or (v) tacrolimus alone. All received corticosteroids. Demographic characteristics were similar among groups. The proportion of patients who met the primary end point (composite of acute rejection, graft loss, death by month 6) was higher in the belatacept groups (42–48%) versus tacrolimus groups (15–38%), with the highest number of deaths and grafts losses in the belatacept LD group. By month 12, the proportion surviving with a functioning graft was higher with tacrolimus + MMF (93%) and lower with belatacept LD (67%) versus other groups (90%: basiliximab + belatacept HD; 83%: belatacept HD; 88%: tacrolimus). Mean calculated GFR was 15–34 mL/min higher in belatacept-treated patients at 1 year. Two cases of posttransplant lymphoproliferative disease and one case of progressive multifocal leukoencephalopathy occurred in belatacept-treated patients. Follow-up beyond month 12 revealed an increase in death and graft loss in another belatacept group (belatacept HD), after which the study was terminated. PMID:25041339

    Full Text Available Aim and Objective: To compare efficacy and safety of escitalopram with desvenlafaxine in the treatment of major depression.Materials and Methods: A total of 60 patients of depression were randomized into two groups after meeting inclusion criterion. In the first 3 weeks, escitalopram 10 mg/day was given and then 20 mg/day for the next 3 weeks in group 1 (n = 30. Desvenlafaxine in the first 3 weeks was given 50 mg/day and 100 mg/day for the next 3 weeks in group 2 (n = 30. The parameters evaluated during the study were efficacy assessments byHamilton Scale of Rating Depression (HAM-D, Hamilton Rating Scale of Anxiety (HAM-A, and Clinical Global Impression (CGI. Safety assessments were done by UKU-scale. Results: Escitalopram and desvenlafaxine significantly (P < 0.001, reduced HAM-D, HAM-A, and CGI scores from their respective base lines. However, on comparison failed show any statistical difference at 3 and 6 weeks of treatment. Escitalopram and desvenlafaxine were both found to be safe and well-tolerated and there was not much difference between the two groups as evident from UKU Scale and their effect on various biochemical parameters. Conclusion: The present study demonstrated similar efficacy and safety in reducing depression and anxiety with both escitalopram and desvenlafaxine, but clinical superiority of one drug over the other cannot be concluded due to limitations of the small sample size.

    2016-01-01

    This study assessed the effect of 1-year regular Tai Chi (TC) on neuromuscular reaction in elderly women. A total of 41 elderly women (55 years-68 years) completed the study. The TC group (n = 21) performed the 24-form TC, while the control group (C, n = 20) was instructed to read newspapers or watch television when the TC group practised. Electromyogram measurements were conducted before and after intervention. After a year-long intervention, the post-test results of between-group neuromuscular reaction time showed significant differences in the rectus femoris (t = 3.607, p = 0.001), semitendinosus (t = 2.678, p = 0.011), anterior tibialis (t = 3.455, p = 0.001), and gastrocnemius muscles (t = 4.061, p = 0.000). Within-group results showed that the TC group had significantly shorter neuromuscular reaction time compared to its baseline value in the rectus femoris (t = 3.066, p = 0.006), semitendinosus (t = 2.485, p = 0.022), anterior tibialis (t = 2.311, p = 0.032), and gastrocnemius muscles (t = 2.462, p = 0.023). Results suggested that year-long regular TC can improve neuromuscular reaction function in elderly women. PMID:27161956

    Objective CT, an important diagnostic tool in the emergency department (ED), might increase the ED length of stay (LOS). Considering the issue of ED overcrowding, it is important to evaluate whether CT use delays or facilitates patient disposition in the ED. Design A retrospective 1-year cohort study. Setting 5 EDs within the same healthcare system dispersed nationwide in Taiwan. Participants All adult non-trauma patients who visited the 5 EDs from 1 July 2011 to 30 June 2012. Interventions Patients were grouped by whether or not they underwent a CT scan (CT and non-CT groups, respectively). Primary and secondary outcome measures The ED LOS and hospital LOS between patients who had and had not undergone CT scans were compared by stratifying different dispositions and diagnoses. Results CT use prolonged patient ED LOS among those who were directly discharged from the ED. Among patients admitted to the observation unit and then discharged, patients diagnosed with nervous system disease had shorter ED LOS if they underwent a CT scan. CT use facilitated patient admission to the general ward. CT use also accelerated patients' admission to the intensive care unit (ICU) for patients with nervous system disease, neoplasm and digestive disease. Finally, patients admitted to the general wards had shorter hospital LOS if they underwent CT scans in the ED. Conclusions CT use did not seem to have delayed patient disposition in ED. While CT use facilitated patient disposition if they were finally hospitalised, it mildly prolonged ED LOS in cases of patients discharged from the ED. PMID:27147387

    While the role of childhood adversity in increasing the risk of psychosis has been extensively investigated, it is not clear what the impact of early adverse experiences is on the outcomes of psychotic disorders. Therefore, we investigated associations between childhood adversity and 1-year outcomes in 285 first-presentation psychosis patients. Exposure to childhood adversity prior to 17 years of age was assessed using the Childhood Experience of Care and Abuse Questionnaire. Data on illness course, symptom remission, length of psychiatric hospitalization, compliance with medication, employment, and relationship status were extracted from clinical records for the year following first contact with mental health services for psychosis. Seventy-one percent of patients reported exposure to at least 1 type of childhood adversity (physical abuse, sexual abuse, parental separation, parental death, disrupted family arrangements, or being taken into care). No robust associations were found between childhood adversity and illness course or remission. However, childhood physical abuse was associated with almost 3-fold increased odds of not being in a relationship at 1-year follow-up compared to patients who did not report such adverse experiences. There was also evidence of a significant association between parental separation in childhood and longer admissions to psychiatric wards during 1-year follow-up and 2-fold increased odds of noncompliance with medication compared to those not separated from their parents. Therefore, our findings suggest that there may be some specificity in the impact of childhood adversity on service use and social functioning among psychosis patients over the first year following presentation to mental health services.

    Callesen, T; Bech, K; Kehlet, H

    1999-01-01

    BACKGROUND: The aim was to provide a detailed description of any residual pain 1 year after elective day-case open groin hernia repair under local anaesthesia. METHODS: This was a prospective consecutive case series study by questionnaire of 500 consecutive operations in 466 unselected adult...... severe pain 4 weeks after operation (24 versus 3 per cent; P < 0.001). CONCLUSION: Chronic pain is a significant problem after open groin hernia repair. It may be worse after surgery for a recurrent hernia and may be predicted by the intensity of early postoperative pain....... severe pain was higher after repair of recurrent than primary hernias (14 versus 3 per cent; P < 0.001). The risk of developing moderate or severe pain was increased in patients who had a high pain score 1 week after operation (9 versus 3 per cent; P < 0.05) and also in patients who had moderate or...

  17. Monitoring benzotriazoles: a 1 year study on concentrations and removal efficiencies in three different wastewater treatment plants.

    Herzog, Bastian; Lemmer, Hilde; Helmreich, Brigitte; Horn, Harald; Müller, Elisabeth

    2014-01-01

    Benzotriazole (BTri), 4- and 5-tolyltriazole (4-TTri, 5-TTri) were monitored over 1 year in three wastewater treatment plants (WWTPs) with a membrane bioreactor (MBR-MH) and two conventional activated sludge systems (CAS-E, CAS-M). The influent/effluent concentrations and treatment stages removal efficiencies were monitored. 5-TTri was removed best (mean removal 80%) in the WWTP mainly by biodegradation followed by BTri (mean removal 45%) and 4-TTri (mean removal 15%) that showed a significant lower elimination. High removal fluctuations for all three benzotriazoles occurred over the four seasons with lowest removal during winter. All three WWTPs constituted a point source for BTs in the aquatic environment as concentration measurements in the receiving rivers upstream and downstream of the WWTP proved. While MBR-MH and CAS-M significantly increased the downstream concentrations, CAS-E only slightly increased the downstream concentrations as the receiving river was already contaminated with benzotriazoles from hydropower. 5-TTri was detected in lowest concentrations due to its good removal compared to BTri and 4-TTri that contribute to high effluent concentrations with the potential to accumulate due to insufficient self-purification.

  18. Predictors and health-related outcomes of positive body image in adolescent girls: A prospective study.

    Andrew, Rachel; Tiggemann, Marika; Clark, Levina

    2016-03-01

    This study aimed to investigate prospective predictors and health-related outcomes of positive body image in adolescent girls. In so doing, the modified acceptance model of intuitive eating was also examined longitudinally. A sample of 298 girls aged 12 to 16 years completed a questionnaire containing measures of body appreciation, potential predictors, and a range of health outcomes, at 2 time points separated by 1 year. Longitudinal change regression models showed that perceived body acceptance by others (positively), self-objectification and social comparison (negatively), and body appreciation (positively) prospectively predicted intuitive eating 1 year later, consistent with the acceptance model of intuitive eating. Perceived body acceptance by others was the only proposed predictor to prospectively predict an increase in body appreciation over time. Time 1 body appreciation prospectively predicted a decrease in dieting, alcohol, and cigarette use, and an increase in physical activity 1 year later. In particular, girls with low body appreciation were more likely than girls with high body appreciation to take up alcohol and cigarette use between time points. The results highlight body appreciation as an important target for interventions designed to prevent or delay the uptake of alcohol and cigarette consumption among girls. More broadly, they suggest that a positive body image can confer considerable benefit for adolescent girls. PMID:26727595

    Full Text Available Stroke is one of the most common causes of epilepsy in elderly. However, there have been very few prospective studies to define the incidence, pattern and outcome of seizures in stroke. Most studies are based on retrospective analysis of hospital records. Hence, we planned this prospective study to see the clinical, radiological and electroencephalographic characteristics of seizures in stroke and their outcome, from a north Indian tertiary care centre. Over a span of approximately 6 years, 269 consecutive patients with stroke were studied and followed up. Thirty-five (13% of these developed seizures, primarily related to stroke, during mean follow up period of 15.9 months. Twenty of these had infarctions while 15 had haemorrhages. Involvement of the cortical region was seen in most of the patients with seizures. In these patients, 86% of the lesions involved cortical areas exclusively or in addition to subcortical areas on CT scan of the brain. Twenty-seven (77% developed early seizures, two third of them had immediate post-stroke seizures. None of the patients with early onset seizures developed recurrent seizures or epilepsy, while 50% of late onset seizures developed epilepsy. No specific EEG pattern was found in those who later developed epilepsy. In the present study, early onset seizures after stroke were rather common and did not affect outcome and did not recur even when not treated with anti-epileptics. Late onset seizures were less common but were associated with recurrent seizures.

    Exposure to caterpillars results in a variety of clinical effects depending on the species involved. The aim of this study was to describe the clinical effects from caterpillar exposures within Australia. Cases were recruited prospectively from calls to a poison information centre. Subjects were included if they had a definite exposure and they had collected the caterpillar or cocoon. The caterpillars were identified to genus and species level where possible. There were 36 included cases: two were contact exposures to caterpillar contents, one was an ingestion of a caterpillar and the remaining 33 patients had definite reactions from caterpillar or cocoon exposure. There were five families of caterpillars identified in the study: Arctiidae, Limacodidae, Anthelidae, Lymantriidae and Sphingidae, many of which occur worldwide. Clinical effects ranged from severe pain to an urticarial response depending on the species involved. There were no adverse effects following ingestion in this study. Treatment consisted primarily of removal of the caterpillar or cocoon. Other treatment measures consisted of symptomatic treatment such as ice packs and antihistamines. This is the first prospective study of caterpillar exposures within Australia and demonstrates that exposures can result in a variety of reactions depending on the family and species involved.

    The aim of the prospective study reported here was to examine the effects of social and economic transformation on dietary patterns and nutritional status in China. The study began in 1989 and continued with follow-ups in 1991, 1993, 1997, 2000, and 2004. A total of 5000 subjects aged 18-45 years from 4280 households in nine provinces were included. Weighed records and three consecutive 24-h recalls were used. Over the study period, average consumption of all animal foods except milk increased, while cereal intake decreased. The proportion of animal protein and fat as a percentage of energy also increased. However, vitamin A and calcium intake did not increase and remained low. Child height and weight increased while undernutrition decreased and overweight increased. The results indicate that rapid changes in dietary pattern are associated with economic reforms in China.

    2011-01-01

    Abstract Background Hip resurfacing arthroplasty (HRA) is considered a bone-preserving procedure and may eliminate proximal femoral stress shielding and osteolysis. However, in addition to implant-related stress-shielding factors, various patient-related factors may also have an effect on bone mineral density (BMD) of the proximal femur in patients with HRA. Thus, we studied the effects of stem-neck angle, demographic variables, and physical functioning on the BMD of the proximal femur in a o...

Studies of such factors are important to develop targeted interventions to improve health. The main purpose of this study is to explore sense of coherence (SOC in a sample of persons with morbid obesity before and after attending a patient education course and to explore the association between SOC and sociodemographic and other personal factors. Methods: In this longitudinal purposely sampled study, the participants completed questionnaires on the first day of the course and 12 months after course completion. Sixty-eight participants had valid scores on the selected variables at follow-up: SOC, self-esteem, and self-efficacy. Relationships were assessed with correlation analyses and paired and independent samples t-tests and predictors with linear regression analyses. Results: From baseline to follow-up, the total SOC score and the subdimension scores comprehensibility, manageability, and meaningfulness all increased significantly. At both time points, the SOC scores were low compared to the general population but similar to scores in other chronically ill. At baseline, a multivariate analysis showed that older age, having paid work, and higher self-esteem were directly related to higher total SOC score after controlling for other sociodemographic factors and the participants' level of self-efficacy. Multivariate analyses of the relationship between baseline predictors of SOC at 12-month follow-up, controlling for baseline SOC scores or sociodemographic or personal factors, revealed that none of these variables independently predicted SOC scores at follow-up. Conclusion: The total SOC score and its

BMD was measured two days and 3, 6, and 12 months postoperatively and 10 regions of interest (ROI were used. Stem-neck angle was analyzed from anteroposterior radiographs. Results Three months postoperatively, BMD decreased in six out of 10 regions of interest (ROI on the side operated on and in one ROI on the control side (p Conclusions After an early drop, the BMD of the upper femur was restored and even exceeded the preoperative level at one year follow-up. From a clinical standpoint, the changes in BMD in these HRA patients could not be explained by stem-neck angle or patient related factors.

  17. Cytogenetic studies for a group of people living in Japan 1 year after the Fukushima nuclear accident

    In order to understand the potential health effect of radiation from Fukushima nuclear disaster, a group of people living in Japan during and after the accident were investigated 1 y after the accident. The venous blood samples were extracted in tune from 156 tested persons living in Tokyo and Niigata with average age of 42.4±10.2 y old as well as 87 controls living in Beijing with similar age and sex proportion. Conventional chromosome culture and cytochalasin B micronucleus methods were applied. The unstable chromosome aberrations of 200 cells and micronuclei (MN) and micronuclei cells (MNC) of 1000 bi-nucleated lymphocytes were analysed for each examined subject. The results showed that the frequencies±SE (x100) of the dicentrics plus rings were 0.17±0.024 % and 0.13±0.028 % in the tested and control populations (p > 0.05), respectively. The frequencies of the extra acentrics were 0.21±0.026 % and 0.06±0.018 % in the tested and control groups (p < 0.01), respectively. The total chromosomal aberration frequencies of the tested and control groups were 0.40±0.036 % and 0.20±0.034 % (p < 0.01), respectively. The MN and MNC frequencies of the tested group were 29.25±3.96 0/00 and 23.85±4.23 0/00, and 25.30±6.45 0/00 and 21.56±3.99 0/00 for control group (p < 0.01). With the exception of dicentrics, there were significant differences (p < 0.01) between two groups in frequencies of chromosome aberration and MN. Generally, 1 y after the Fukushima nuclear accident, the dicentric frequencies had not increased in the 156 persons investigated in this study. The increase in chromatid aberrations, chromosomal acentrics and MN was induced but could not be directly linked to radiation exposures, as an excess of dicentric frequency is linked. However, the observed higher frequency of chromosomal alterations might be related to exposure to the low doses of ionising in this cohort. Consequently, it is recommended to assess the long-term health effects in this

    Full Text Available Introduction: The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best.   Materials and Methods: A prospective study of 80 patients who underwent ossiculoplasty was performed in the ear, nose, and throat (ENT department at a tertiary health care facility from 2011 to 2013. Patients with chronic suppurative otitis media with an air-bone gap (ABG of >25 dB with ossicular involvement were included in the study. Total ossicular replacement prosthesis (TORP, partial ossicular replacement prosthesis (PORP, and refashioned incus were used. Success was defined as ABG   Results: The majority patients were of middle age with moderate conductive hearing loss. Incus was the most susceptible ossicle. Overall success rate in this study was 80.0% with an average change of 15.76 dB in ABG.   Conclusion:  With continuing advances in our understanding of middle ear mechanics, the results of ossiculoplasty are improving and results can be very rewarding in experienced hands. Severity of preoperative ear discharge, preoperative mastoid cellularity, presence of disease, and surgical procedure proved to be significant prognostic factors. Autograft incus and PORP fared better when the malleus handle was present while TORP gave better results when the malleus handle was eroded.  

  3. Ion cyclotron emission studies: Retrospects and prospects

    Gorelenkov, N. N.

    2016-05-01

    Ion cyclotron emission (ICE) studies emerged in part from the papers by A.B. Mikhailovskii published in the 1970s. Among the discussed subjects were electromagnetic compressional Alfvénic cyclotron instabilities with the linear growth rate √ {n_α /n_e } driven by fusion products, -particles which draw a lot of attention to energetic particle physics. The theory of ICE excited by energetic particles was significantly advanced at the end of the 20th century motivated by first DT experiments on TFTR and subsequent JET experimental studies which we highlight. More recently ICE theory was advanced by detailed theoretical and experimental studies on spherical torus (ST) fusion devices where the instability signals previously indistinguishable in high aspect ratio tokamaks due to high toroidal magnetic field became the subjects of experiments. We discuss further prospects of ICE theory applications for future burning plasma (BP) experiments such as those to be conducted in ITER device in France, where neutron and gamma rays escaping the plasma create extremely challenging conditions fusion alpha particle diagnostics.

  4. EPR Dosimetry: an update and prospective studies

    kGy for thermal neutron flux. The radiation induced radical signal was found to be stable over a period of 300 days with marginal fading of 2C2O4: Na2C2O4 mixture as the potential neutron dosimeter for high range dosimetry. The effect of gamma dose irradiation on sodium succinate was studied by EPR technique. It was observed that the radiation induced CO3- radical (g = 2.00357) as linear in signal - dose response, in 35 Gy - 4.4 kGy. Thus, sodium succinate powder samples could be used in EPR dosimetry, since CO3- radicals have been found stable for more than 6 months, post-irradiation. Solid State Nuclear Track Detector (SSNTD) material Tuffak polycarbonate film was studied for prospective EPR dosimetry, feasibility studies were carried out on gamma irradiated SSNTD film. The first derivative EPR spectra of irradiated Tuffak polycarbonate samples contained a singlet, signal at g = 2.00415. The signal was identified as CO33- from earlier reports. The EPR signal intensity of CO33- (g = 2.00415) was found linear in signal - dose response in 10 - 80 kGy. The present paper gives an update of newer EPR dosimetric materials that have been investigated, after a brief introduction to the basic principles of EPR. Further, prospective dosimetric materials with their suitability for applications in EPR dosimetry have been discussed. (author)

    2010-06-01

    Full Text Available The effect of physical exercise on the treatment of depressive elderly adults has not been investigated thus far in terms of changes in cortical hemispheric activity. The objective of the present study was to identify changes in depressive symptoms, quality of life, and cortical asymmetry produced by aerobic activity. Elderly subjects with a diagnosis of major depressive disorder (DSM-IV were included. Twenty patients (70% females, 71 ± 3 years were divided into an exercise group (pharmacological treatment plus aerobic training and a control group (undergoing pharmacological treatment in a quasi-experimental design. Pharmacological treatment was maintained stable throughout the study (antidepressants and anxiolytics. Subjects were evaluated by depression scales (Beck Depression Inventory, Hamilton Depression Rating Scale, Montgomery-Asberg Depression Rating Scale and the Short Form Health Survey-36, and electroencephalographic measurements (frontal and parietal alpha asymmetry before and after 1 year of treatment. After 1 year, the control group showed a decrease in cortical activity on the right hemisphere (increase of alpha power, which was not observed in the exercise group. The exercise group showed a significant decrease of depressive symptoms, which was not observed in the control group. This result was also accompanied by improved treatment response and remission rate after 1 year of aerobic exercise associated with treatment. This study provides support for the effect of aerobic training on alpha activity and on depressive symptoms in elderly patients. Exercise facilitates the treatment of depressive elderly adults, leading to clinical and physical improvement and protecting against a decrease in cortical activity.

  6. The Development of Musical Skills of Underprivileged Children Over the Course of 1 Year: A Study in the Context of an El Sistema-Inspired Program.

    2016-01-01

    Developmental research in music has typically centered on the study of single musical skills (e.g., singing, listening) and has been conducted with middle class children who learn music in schools and conservatories. Information on the musical development of children from different social strata, who are enrolled in community-based music programs, remains elusive. This study examined the development of musical skills in underprivileged children who were attending an El Sistema-inspired program in Los Angeles. We investigated how children, predominantly of Latino ethnicity, developed musically with respect to the following musical skills - pitch and rhythmic discrimination, pitch matching, singing a song from memory, and rhythmic entrainment - over the course of 1 year. Results suggested that participation in an El Sistema-inspired program affects children's musical development in distinct ways; with pitch perception and production skills developing faster than rhythmic skills. Furthermore, children from the same ethnic and social background, who did not participate in the El Sistema-inspired music program, showed a decline in singing and pitch discrimination skills over the course of 1 year. Taken together, these results are consistent with the idea of musical development as a complex, spiraling and recursive process that is influenced by several factors including type of musical training. Implications for future research are outlined. PMID:26869964

    Dow Corning SE 1700 (reinforced polydimethylsiloxane) porous structures were made by direct ink writing (DIW). The specimens (~50% porosity) were subjected to various compressive strains (15, 30, 45%) and temperatures (room temperature, 35, 50, 70°C) in a nitrogen atmosphere (active purge) for 1 year. Compression set and load retention of the aged specimens were measured periodically during the study. Compression set increased with strain and temperature. After 1 year, specimens aged at room temperature, 35, and 50°C showed ~10% compression set (relative to the applied compressive deflection), while those aged at 70°C showed 20-40%. Due to the increasing compression set, load retention decreased with temperature, ranging from ~90% at room temperature to ~60-80% at 70°C. Long-term compression set and load retention at room temperature were predicted by applying time-temperature superposition (TTS). The predictions show compression set relative to the compressive deflection will be ~10-15% with ~70-90% load retention after 50 years at 15-45% strain, suggesting the material will continue to be mechanically functional. Comparison of the results to previously acquired data for cellular (M97*, M9760, M9763) and RTV (S5370) silicone foams suggests that the SE 1700 DIW porous specimens are on par with, or outperform, the legacy foams.

  16. Pros and cons of a wandering mind: A prospective study

    Cristina eOttaviani

    2013-08-01

    Full Text Available Mind wandering (MW has recently been associated with both adaptive (e.g., creativity enhancement and maladaptive (e.g., mood worsening consequences. This study aimed at investigating whether proneness to MW was prospectively associated with negative health outcomes. At time 0, 21 women, 19 men; mean age = 24.5 (4.9 underwent a 5-min baseline electrocardiogram (ECG, a 20-min laboratory tracking task with thought probes, and personality questionnaires. At time 1 (1 year follow-up, the same participants underwent a 24-hour Ecological Momentary Assessment characterized by ambulatory ECG recording and electronic diaries. First, we examined if the likelihood of being a ‘mind wanderer’ was associated with specific personality dispositions. Then, we tested if the occurrence of episodes of MW in the lab would be correlated with frequency of MW in daily life. Finally, multiple regression models were used to test if MW longitudinally acted as a risk factor for health, accounting for the effects of biobehavioral variables. Among dispositional traits, the frequency of MW episodes in daily life was inversely associated with the capacity of being mindful (i.e., aware of the present moment and non-judging. There was a positive correlation between frequency of MW in the lab and in daily life, suggesting that it is a stable disposition of the individual. When differentiated from perseverative cognition (i.e., rumination and worry, MW did not predict the presence of health risk factors one year later, however, a higher occurrence of episodes of MW was associated with short-term adverse consequences, such as increased 24-hour heart rate on the same day and difficulty falling asleep the subsequent night. Present findings suggest that MW may be associated with short term ‘side effects’ but argue against a long term dysfunctional view of this cognitive process.

  20. Anaemia management with subcutaneous epoetin delta in patients with chronic kidney disease (predialysis, haemodialysis, peritoneal dialysis: results of an open-label, 1-year study

    Kwan Jonathan TC

    2009-02-01

    Full Text Available Abstract Background Anaemia is common in patients with chronic kidney disease (CKD and can be managed by therapy with erythropoiesis-stimulating agents (ESAs. Epoetin delta (DYNEPO®, Shire plc is the only epoetin produced in a human cell line. The aim of this study was to demonstrate the safety and efficacy of subcutaneously administered epoetin delta for the management of anaemia in CKD patients (predialysis, peritoneal dialysis or haemodialysis Methods This was a 1-year, multicentre, open-label study. Patients had previously received epoetin subcutaneously and were switched to epoetin delta at an identical dose to their previous therapy. Dose was titrated to maintain haemoglobin at 10.0–12.0 g/dL. The primary endpoint was mean haemoglobin over Weeks 12–24. Secondary analyses included long-term haemoglobin, haematocrit and dosing levels. Safety was assessed by monitoring adverse events, laboratory parameters and physical examinations. Results In total 478 patients received epoetin delta, forming the safety-evaluable population. Efficacy analyses were performed on data from 411 of these patients. Mean ± SD haemoglobin over Weeks 12–24 was 11.3 ± 1.1 g/dL. Mean ± SD weekly dose over Weeks 12–24 was 84.4 ± 72.7 IU/kg. Haemoglobin levels were maintained for the duration of the study. Epoetin delta was well tolerated, with adverse events occurring at rates expected for a CKD patient population; no patient developed anti-erythropoietin antibodies. Conclusion Subcutaneously administered epoetin delta is an effective and well-tolerated agent for the management of anaemia in CKD patients, irrespective of dialysis status.

    Full Text Available BACKGROUND AND OBJECTIVES: Low back pain (LBP results in loss in productivity than any other medical condition. Approximately 70 - 80% of all people will develop LBP in their life . There are various causes of LBP , out of which the lumber disc herniation is one of the most frequent reason for physical , functional restriction in patients. Patients who have u ndergone surgical treatment are found to possess increased short term outcome instead of conservative treated patients. Surgically treated patients experienced fast pain relief , improvement of function & satisfaction in comparison to conservative patients. The comparative results of patients treated with surgery and conservatively treated patients have revealed that surgical treatment is much better at short term follow up (upto 1 year however no variations have been shown among treatment at long term foll ow up. Some patients operated for spine diseases are still left with poor results. The present study aims to evaluate the efficiency of open discectomy for L 4 – L 5 IVDP prospectively. METHODS : 30 cases of lumbar disc prolapse , above 18 years of age admitte d at KIMS hospital , Bangalore with MRI showing conclusive disc prolapsed were taken for the study. They were pre operatively evaluated for their ODI score. Only those patients who have scored 40% and above in ODI were included in the study. They underwent dis c ectomy. Methods of surgery used were fenestration , extended fenestration , hemilaminectomy & total laminectomy as per operative requirement. Follow - ups were carried out at 6 , 12 and 24weeks on selected areas. Pre and post of ODI total and sub scale scor es were compared at the end of 24 weeks. RESULTS : There was a significant reduction of post operative ODI score indicating good success rate in open disectomy. The pre operative mean ODI score was 58.28 , SD was 5.06 and the post operative mean ODI score wa s 15.28 and SD was 2.40 with t value of 38.56 and p value of

    2009-09-01

    Full Text Available Abstract Background Opioid analgesics have proven efficacy in the short-term management of chronic cancer pain, but data on their long-term use is more limited. OROS® hydromorphone is a controlled-release formulation of oral hydromorphone that may be particularly well suited to long-term management of chronic cancer pain because it provides stable plasma concentrations and consistent analgesia with convenient once-daily dosing. The objective of this study (DO-118X was to characterise the pain control achieved with long-term repeated dosing of OROS® hydromorphone in patients with chronic cancer pain. Methods In this multicentre, phase III, open-label, single treatment, 1-year extension study, OROS® hydromorphone was administered to 68 patients with moderate-to-severe chronic cancer pain, who had successfully completed a short-term equivalence study, and whose pain was controlled with a stable dose of medication (≥ 8 mg OROS® hydromorphone or equivalent controlled-release morphine. Patients were started on the dose of OROS® hydromorphone equivalent to the opioid dose on which they achieved dose-stable pain control in the equivalence study; dose adjustments were made as necessary and breakthrough pain medication was permitted. Efficacy was assessed with the Brief Pain Inventory (BPI and patient and investigator global evaluations of treatment effectiveness. No formal statistical analysis was done. Results The mean (standard deviation duration of exposure to study medication was 139 (129.9 days and the mean (standard deviation average daily consumption of OROS® hydromorphone was 43.7 (28.14 mg/day. All scores were maintained at a mild to moderate severity throughout the study; however, BPI scores for pain at its worst, pain at its least, pain on average, pain right now, and pain relief were slightly worsened at end point compared with baseline.

    2016-01-01

    The objective of this study was to evaluate and compare the clinical efficacy of periosteal pedicle graft (PPG) and acellular dermal matrix allograft (ADMA) in conjunction with coronally advanced flap (CAF) in the treatment of gingival recession during a 1-year follow-up. A sample of 14 patients, each with two similar Miller Class I or II gingival recession (28 recession sites), was selected. Each recession site was randomly assigned to the experimental site (PPG + CAF) or the control site (ADMG + CAF). The clinical parameters recorded at baseline and 12 months postoperatively were probing pocket depth, width of keratinized gingiva, and clinical attachment level, whereas full-mouth and site-specific plaque and gingival index and vertical recession depth and width were recorded at baseline and at 1, 3, 6, 9, and 12 months. Analysis was performed to determine if treatment differences were present. The mean recession depth in experimental sites decreased from 2.89 ± 0.40 mm at baseline to 0.25 ± 0.50 mm at 12 months, corresponding to a mean root coverage of 92.79% ± 14.25%. In control sites, recession shrank from 2.93 ± 0.55 mm at baseline to 0.32 ± 0.46 mm at 12 months follow-up, demonstrating a mean root coverage of 89.79% ± 14.73%. Compared to the use of ADMA, the PPG technique uses similar incision design and flap management at the graft site, is equivalent in technique sensitivity, and has a perceived improvement in esthetic outcome.

    2016-01-01

    Background: Deep brain stimulation (DBS) has been a promising treatment for patients with refractory Tourette syndrome (TS) for more than a decade. Despite successful DBS treatment of TS in more than 100 patients worldwide, studies with a large patient sample and long-term follow-up assessments are still scarce. Accordingly, we investigated the clinical efficacy and safety of globus pallidus internus (GPi) DBS in the treatment of intractable TS in 24 patients with a 1-year follow-up assessment. Methods: Bilateral/unilateral GPi-DBS was performed in 24 patients with TS. We evaluated symptoms of tics and obsessive-compulsive disorder (OCD) through the Yale Global Tic Severity Scale (YGTSS) and Yale-Brown Obsessive-compulsive Scale (Y-BOCS). We used the Wechsler Adult Intelligence Scale-Revised in China (WAIS-RC) to evaluate the safety of the treatment. We conducted follow-up assessments of all patients for at least 12 months (12–99 months). Results: Symptoms of tics and OCD were significantly relieved at a 12-month follow-up assessment. The mean YGTSS score was 74.04 ± 11.52, 49.83 ± 10.91, 32.58 ± 7.97, and 31.21 ± 8.87 at baseline, 3, 6, and 12 months, respectively. The mean YGTSS scores obtained at the follow-up assessments were significantly different from the baseline (P < 0.05). The improvement in motor tics was superior to that in phonic tics. The mean Y-BOCS scores were 21.61 ± 4.97, 18 ± 4.58, 14.39 ± 3.99, and 13.78 ± 4.56 at baseline, 3, 6, and 12 months, respectively (P < 0.05). We observed a remarkable improvement in psychiatric comorbidities, such as OCD and attention-deficit hyperactivity disorder, after the procedure. WAIS-RC scores were comparable before and after the operation. There were no severe postoperative complications. Conclusion: GPi-DBS appears to comprehensively alleviate tic symptoms and psychiatric comorbidities in patients with TS, thus significantly improving patients’ quality of life. PMID:27098785

  9. Surface reflectance and material studies for the PROSPECT Experiment

    Bowes, Alyssa; Prospect Collaboration

    2015-10-01

    The PROSPECT Experiment aims to probe the existence of sterile neutrino oscillations by measuring the energy spectrum of antineutrinos emanating from nuclear reactors in a matrix of optically separated target scintillator cells at a variety of reactor-detector baselines. By measuring the absolute spectrum we also learn about reactors and what isotopes they produce. In order to properly model and optimise PROSPECT's energy resolution and background rejection capabilities, the reflective properties of the cell surfaces must be well understood. To address this, a study of various reflective surfaces under consideration to be used in the detector was conducted at non-normal incident angles through liquid using a custom-built laser-based reflectance measurement system. This presentation will describe the apparatus, reflectance measurements, and implications for the PROSPECT optical cell performance. Future plans to incorporate measurements into existing optical simulations will also be discussed. Funding provided by Illinois Institute of Technology College of Science.

  19. Backache amongst soldiers: a prospective analytical study

    Objective: To investigate the occupational predispositions of low back pain in soldiers Study Design: Descriptive study. Place and Duration of Study: Combined Military Hospital, Bahawalpur, from June 2009 to Jan 2010. Patients and Methods: A questionnaire was developed to investigate the occupation-related issues in soldiers reporting with low backache in surgical OPD at CMH Bahawalpur. It included personal and occupational factors. The body mass index was also calculated. Of the 107 male soldiers assessed, 90 were enrolled into the study. The statistical analysis was performed by descriptive analysis of the data using SPSS 17.0. Results: Of all the soldiers evaluated (n=90), 32 (35.6%) were clerks/computer operators, 21 (23.1%) were drivers and 14(15.6%) were signal men. All were males (100%) and the average BMI was 24.8 kg/m2. The 69 (76.7%) patients who had backache had prolonged working hours (average 10.8 hours per day), 68 (75.6%) patients used to sleep over tape/nawar bed and only 12 (13.3%) had been sleeping on mattresses. The onset of pain was sudden in 58 (64.4%) patients. 27 (23.3%) had developed acute backache after prolonged sitting, 21 (30%) after lifting heavy objects. The pain was exaggerated by doing morning physical training 82 (91.1%), prolonged sitting 61 (67.8%) and standing with rifle 24 (26.7%). Conclusion: The prevalence of low back pain in sedentary occupation or soldiers on sitting jobs was higher 69 (76%). The number of working hours on these occupations was associated with occurrence as well as aggravation of low back pain. (author)

    2012-10-01

    Tuberculosis (TB) is considered to be a disease of poverty, since its incidence is exacerbated by socioeconomic factors, inconsistent or partial treatment practices, and immigration from endemic countries. A prospective country level study, using a comprehensive dataset of TB incidence and prevalence taken from countries within the World Health Organization (WHO) European region, was conducted. We employed quintile regression to investigate the prospective association between baseline (measured in 2000) and a nation's wealth, level of egalitarianism, migration rate, health-related lifestyle and social capital with TB incidence and prevalence over a 10-yr period (2000-2009). We found that ∼50% of TB variation is accounted for by a nation's wealth and level of egalitarianism. We observed a negative prospective association between logged gross domestic product and TB rates, and a positive prospective association between income inequality and TB. National income levels per capita and income inequality are important predictors for TB incidence and prevalence in the WHO European region. They account for 50% of country-level variation, indicating the importance of a combined absolute and relative socioeconomic disadvantage in the development of TB. These findings also provide a tool for forecasting potential fluctuations in the level of TB epidemics in the WHO European region, with respect to socioeconomic changes. PMID:22267772

    Full Text Available BACKGROUND Breast cancer is the most frequently diagnosed cancer in women and the second most cause of death in cancer. Over the past several decades there has been increase in incidence of the disease. Analysis of the incidence, clinical presentations, various risk factors, accuracy of FNAC and frozen section, incidence of various pathological types, stage at presentation and ER, PR, HER-2/neu status. METHODS In this prospective study, 51 consecutive patients who were diagnosed to have carcinoma breast admitted between April 2013 to April 2014 in the Department of Surgery, Rajarajeshwari Hospital, Bangalore, were included in the study. A detailed clinical history was elicited from all patients at the time of admission. All patients who had triple assessment evidence of malignancy were worked up for surgery with necessary investigations. Written consent was obtained from each patient for surgery. After data collection, it was checked, verified, edited manually for consistency to reduce error. Descriptive and graphical methods were used in analysing the data. The important variables were considered and analysed to fulfil the objective of the study. RESULTS In our study, the incidence of carcinoma breast is 5.6 per 1000, 32% of them were between 41-50 year age group, 63.3% had early menarche, 14.3% were nulliparous. Nearly 84.3% of them presented with lump of which 54% left sided involving upper outer quadrant 54.9%. Most cases belong to stage II and stage III at the time of presentation. FNAC was done in all cases with accuracy rate of 82.4%, followed by frozen section which showed about 71.4% of accuracy for those false negative cases. CONCLUSION Various risk factors in relation to breast carcinoma have been proved. As most of the cases presented late in our series because of lack of awareness, proper awareness and early screening by breast self-examination and mammogram should be emphasized. FNAC proved to be a simple and reliable procedure

    Numerous cross-sectional studies have noted significant negative associations between circulating levels of 25-hydroxyvitamin D and cardiometabolic risk factors, highlighting potential extraskeletal functions of this sterol hormone. Prospective studies, however, have been limited; and hence, no cause-and-effect relations can be inferred. This study aims to determine whether vitamin D status correction can reverse already established manifestations of the metabolic syndrome (MetS). A total of 59 adult nondiabetic, overweight, and obese Saudis (31 male, 28 female) were prospectively enrolled in this 1-year interventional study. Anthropometry and biochemical evaluation were performed, including determination of serum 25-hydroxyvitamin D, calcium, and phosphorous concentrations, as well as fasting blood glucose and lipid profile. Subjects were advised to regularly expose themselves to sunlight and increase intake of vitamin D-rich foods. All measurements were repeated 6 and 12 months later. At the initial baseline visit, the prevalence of both low high-density lipoprotein cholesterol and hypertension was significantly increased among patients with 25-vitamin D deficiency (P definition decreased from 25.2% to 13.0%; and this was largely due to a parallel decrease in the prevalence of low high-density lipoprotein cholesterol, triglycerides, and hypertension. Optimization of vitamin D status through sun exposure and increased intake of a vitamin D-rich diet can lead to an improved cardiometabolic profile, offering a promising nonpharmacologic approach in the prevention of MetS manifestations.

    Different hormones and peptides involved in inflammation have been studied in and related to obesity. The aim of our work is to assess the variations of different molecules related to inflammation in obese patients during the first year following sleeve gastrectomy. This was a prospective study on patients who underwent sleeve gastrectomy. The variations in different clinical, anthropometric, and analytical parameters related to inflammation were determined and analysed in all patients at the preoperative visit and at the first and fifth days, first and sixth months, and 1 year following surgery. We enrolled 20 patients to the study. The median body mass index (BMI) before intervention was 48.5 kg/m2. With respect to comorbidities, 70% of the patients had obstructive sleep apnoea syndrome (OSA), 65% high blood pressure, 45% dyslipidaemia, and 40% diabetes mellitus (DM). The median percentage of BMI lost (%BMIL) 1 year after the intervention was 71%. The dyslipidaemia healing or improvement rate was 100%, whereas it was 87.5% for diabetes, 84.6% for hypertension, and 57.1% for OSA. During the 1-year postintervention period, the average levels of adiponectin increased, although not significantly, whereas those of leptin significantly decreased. In addition, the blood levels of MCP-1, IL-6, CRP, ferritin, and PAI-1 significantly decreased in that period. Sleeve gastrectomy is a surgical technique that is associated with improvements in body weight and comorbid conditions from the first postoperative months, which lead to significant variations in the levels of different inflammation-related parameters and a decrease in the levels of leptin, IL-6, CRP, MCP-1, ferritin, and serpin (PAI-1).

A neurologist examined patients in admission and followed them by phone call 1-year after intervention.Mean modified Rankin Scale (MRS score at the time of admission in endovascular group was 2.86 ± 0.974 whereas it was 3.81 ± 1.078 in surgical clipping group (P = 0.0040. Focal neurologic signs were higher in clipping during procedures (P = 0.0310. Of 37 patients who followed up for a year, 19 were in endovascular group and 18 in surgical clipping group. At 1 year follow-up, MRS improvement was statistically significant in coiling group (P = 0.0090, but not in clipping group (P = 0.8750. Mean difference of MRS score at the time of admission and at one year later, was 0.947 ± 1.224 in endovascular group and 0.111 ± 2.083 in surgical group (P = 0.3000.There was no statistically significant difference at 1 year outcome between two groups. We recommend further interventional studies with larger sample sizes for better evaluation of the modalities.

    The standard surgical management of hip fractures is associated with tissue trauma and bleeding which are added to the fracture injury. The percutaneous compression plate (PCCP) is a minimally invasive device that has been demonstrated in previous studies to reduce postoperative complications and blood loss. This prospective, multi-center, observational study assessed clinical and functional outcomes with PCCP as treatment for trochanteric fractures. Patients with a stable or unstable proximal femoral fracture of type AO 31.A1 or 31.A2 were enrolled in eight hospitals in Italy. The primary outcome of interest was the recovery of the pre-fracture functional status at 1-year follow-up; secondary outcomes of interest included blood transfusions, surgical time, complications, and mortality. A total of 273 patients were enrolled. The ASA score was 3 or 4 in 72.5 % of patients. The mean surgical time was 44.1 min; the mean post-surgery blood transfusions was 0.9 units. At 1 year, 48 patients (17.6 %) died, 28 (10.2 %) were lost to follow-up, 4 patients (1.5 %) were excluded, hence 193 patients (70.3 %) were available for final evaluation. At the 1-year follow-up visit, 51.9 % of patients recovered or improved their pre-fracture modified Harris Hip Score, 49.1 % of patients improved or maintained their walking abilities, and 66.6 % of patients residing at home pre-surgery maintained their domicile. The overall mortality rate was 17.6 %. Major complications included two fracture collapses, one excessive sliding of the cephalic screw leading to a partial fracture collapse and one back-out of the diaphyseal screw. This study demonstrates that treatment of trochanteric fractures with PCCP gives good outcomes and significant advantages such as low blood loss, short surgical time, low risk of complications, and good functional recovery in the majority of the patients.

    Full Text Available Abstract Background All medical schools must counsel poor-performing students, address their problems and assist them in developing into competent physicians. The objective of this study was to determine whether students with academic deficiencies in their M-1 year graduate more often, spend less time to complete the curriculum, and need fewer attempts at passing USMLE Step 1 and Step 2 by entering the Decompressed Program prior to failure of the M-1 year than those students who fail the M-1 year and then repeat it. Method The authors reviewed the performance of M-1 students in the Decompressed Program and compared their outcomes to M-1 students who failed and fully repeated the M-1 year. To compare the groups upon admission, t-Tests comparing the Cognitive Index of students and MCAT scores from both groups were performed. Performance of the two groups after matriculation was also analyzed. Results Decompressed students were 2.1 times more likely to graduate. Decompressed students were 2.5 times more likely to pass USMLE Step 1 on the first attempt than the repeat students. In addition, 46% of those in the decompressed group completed the program in five years compared to 18% of the repeat group. Conclusion Medical students who decompress their M-1 year prior to M-1 year failure outperform those who fail their first year and then repeat it. These findings indicate the need for careful monitoring of M-1 student performance and early intervention and counseling of struggling students.

    Full Text Available Background: Nosocomial infections are an important cause of mortality in neonatal intensive care units (NICUs. Therefore, in this study, the incidence and prevalence of nosocomial infections were determined in NICUs of the three largest neonatal centers in northwest Iran, and the causative bacteria were identified in order to provide potential solutions to control the infections in these hospitals. Materials and Methods: This is a descriptive-prospective study in which the cases of nosocomial infections were examined in the three largest hospitals in Tabriz in northwest Iran during 1 year (from June 2012 until May 2013 based on clinical findings, medical and nursing reports of patients, and laboratory results. Results: Of the 3129 patients hospitalized in NICUs of the three hospitals, 208 patients were diagnosed with nosocomial infections. The incidence rate of nosocomial infections was 11.34%.per 100 patient days with 52.4% bacteremia, 32.69% pneumonia, 5.77% urinary tract infections, 5.29% wound infections, and 3.85% necrotizing enterocolitis. There was a statistically significant relationship between invasive procedures (such as umbilical catheters, central venous catheters, surgery, and TPN and sepsis (P = 0.001. The relationships between urinary tract infection and urinary catheter (P = 0.000, and aggressive procedures (such as suctioning and intubation and pneumonia (P = 0.001 were also statistically significant. Conclusion: Incidence of nosocomial infections in premature and low birth weight newborns is considered as a health threat. The findings of this research reiterate the importance of giving further attention to prevention and control of nosocomial infections in the NICU.

  7. Study for an energy prospective concerning the France. Final report

    This study aims to define two scenari in the energy prospective domain: a underlying scenario of reference at 2030 following a classical method, and a ''factor 4'' scenario following a more teleological method. In the first scenario the energy demand and the economical framework are presented and the following sectors discussed in terms of simulation and hypothesis for 2030: the industry, the transports, the residential sector and the ternary. The scenario is extrapolated to 2050. In the second scenario the main orientations and the framework are discussed with evaluation for the industry, the transports, the residential and the ternary sectors. The energy accounting for the France are also discussed. (A.L.B.)

  8. Anxiety and depression in patients receiving radiotherapy. Prospective study

    The objective of this study was to detect the prevalence of anxiety and depressive disorders using the Hospital Anxiety and Depression Scale (HADS) prospectively in patients receiving Radiotherapy (RT) during and after treatment. 140 consecutive cancer patients referred for radiotherapy and their care givers were included. All patients were administered the Hospital Anxiety and Depression Scale (HADS) conducted at intake, just before starting RT, after finishing the course of RT, and at 3-4 months follow-up. Anxiety and depression are detected frequently in patients receiving RT both prior to treatment and later during follow-up

  9. A prospective study of urinary tract infection during pelvic radiotherapy

    The frequency of urinary tract infection before and during pelvic radiotherapy was studied prospectively in 172 patients who were not catherised and had not had instrumentation for at least 4 weeks prior to radiotherapy. The incidence of urinary tract infection prior to radiotherapy was 17% and a further 17% of patients develped a urinary tract infection during radiotherapy. Mid-stream specimens of urine (MSU) should be examined for infection on a weekly basis during pelvic radiotherapy not only to identify this additional 17% of patients but also to detect those patients who have persistent urinary tract infection in spite of treatment with appropriate antibiotics.

  13. Prospect Theory: A Study of the Endowment Effect

    Jurandir Sell Macedo

    2007-01-01

    Full Text Available Behavioral Finance is a recent field of study which contradicts the presupposition supported by Modern Finance that decision makers act rationally. Prospect Theory, developed by Kahneman and Tversky (1979, is presented as an alternative model to the Theory of Expected Utility in relation to the way people decide in face of possibilities of risk. According to Prospect Theory, people define gains and losses based on a given point of reference, which can be established on grounds of a given level of expected gain. This fact leads to the Endowment Effect - a behavioral trend investigated in this study – whereby investors are influenced by a portfolio which they have received as an inheritance or endowment. The reason this occurs is that individuals usually define their expectations of gain according to the future profitability of the portfolio received, and not according to the future profitability of the market. Using an investment simulation, the Endowment Effect was tested among 226 university students taking courses in the subject of capital markets. The results demonstrate that the students were influenced by the different initial portfolios, which were randomly assigned.

  14. A Prospective Study of Nonsuppurative Complications of Streptococcal Pharyngitis

    2016-03-01

    Full Text Available Objective: Group A Streptococci (GAS are the most important bacterial cause of pharyngitis. Antibiotic therapy can be prescribed and failure to treat it is associated with suppurative and nonsuppurative complications. Nonsuppurative complications occur after a latency period of a few weeks and include acute rheumatic fever, scarlet fever, streptococcal toxic shock syndrome, acute glomerulonephritis, and pediatric autoimmune neuropsychiatric disorder associated with group A streptococci. The aim of this study is to investigate the frequency of nonsuppurative complications in properly treated children with GAS pharyngitis. Methods: We investigated the frequency of nonsuppurative complications in 1030 proven GAS pharyngitis patients between 5 and 15 years old, who were properly treated by a prospective observational study. All patients diagnosed with GAS pharyngitis were followed up prospectively using a standard form for six months made by monthly phone calls. Results: All the isolates recovered from the patients were susceptible to penicillin. Twentyseven (2.6% patients developed scarlet fever. No other nonsuppurative complications occured in our patient cohort. Conclusions: Penicillin remains the drug of choice for treatment of GAS pharyngitis. The rate of nonsuppurative complications of GAS pharyngitis has decreased significantly in the antibiotic era. J Microbiol Infect Dis 2016;6(1: 8-11

    2010-03-01

    In this prospective study, we examine the workload of the North London Obesity Surgery Service Bariatric telephone support line (BTSL) and its effects on service provision. Over a 3-month period (June to August 2008), a prospective record was kept of all calls, who they were from, whether the patient was presurgery or postsurgery, the type of procedure planned or undertaken, the nature of the enquiry, and the time taken to answer the query. Seventy-five (72%) calls were related to patients who were postsurgery and 29 (28%) presurgery. Patients scheduled for or having undergone Roux-en-Y gastric bypass accounted for 46 (44%) calls; 24 (23%) were preprocedure and 22 (21%) postprocedure. Patients scheduled for or having undergone gastric banding accounted for 56 (54%) calls; five (0.5%) were preprocedure and 51 (49%) postprocedure. Patients undergoing sleeve gastrectomy accounted for two (<1%) calls. Both calls were postprocedure. The reason for the support line enquiry was psychological support in 15 (14%) patients, questions postsurgery in 26 (25%), general enquiries in 27 (26%), and clinical enquiries in 36 (36%). This study of the BTSL has allowed us to identify areas of need within our bariatric population and improve the service we deliver. The changes we have made should lead to a better use of the team's time, greater patient compliance, and satisfaction as well as reduced complaints and litigation. PMID:19711140

    2016-01-01

    Total knee arthroplasties (TKAs) are reliable procedures for treating end-stage knee osteoarthritis with excellent long-term outcomes. The purpose of this study was to longitudinally evaluate temporal trends of Knee Society Scores (KSS) after TKA and to identify potential demographic and comorbid factors that affect these outcomes. This prospective study evaluated 281 patients (108 men and 173 women) with a mean age of 66 years (range, 39-80 years) who underwent primary TKA (minimum follow-up 5 years). During each follow-up visit, KS objective, function, and total scores were evaluated. The effects of different demographics and comorbidities on outcomes were further analyzed using multivariate regression analysis. Following TKA, peak mean KSS were observed at 1-year follow-up (mean, 92 points), after which there was no significant difference in scores at 5 years compared with 1-year follow-up (mean, 92 points). KS function scores were observed to be unchanged from preoperative levels (mean, 53 points) and at 6 weeks (mean, 56 points). These were significantly higher at 3 months (mean, 78 points) and reached a maximum mean peak at 1 year (mean, 85 points). KS objective scores increased earlier than function scores. The demographic variables and comorbidities that demonstrated a significantly negative impact in KS function scores were increased age, female gender, higher body mass index, and several medical comorbidities including immunological and neurological disease, and neoplasm. Race was the only variable that significantly decreased the KS objective scores. KSS after TKA follow temporal trends with scores initially unchanged from preoperative levels for the objective component, but the scores increased for the functional component. All components demonstrated higher levels compared with preoperative scores by 3 months and peaked at 1-year follow-up. At 5-year follow-up, all mean KSS were unchanged relative to peak scores seen at 1 year. Various patient

  3. Carbon ion radiotherapy. Clinical study and future prospect

    At present, most of the patients receiving carbon ion radiotherapy at National Institute of Radiological Sciences (NIRS) visit the clinic seeking this specific modality, and it is difficult to obtain consent for a randomized controlled study from these patients and it may be unnecessary to conduct a phase III trial. However, in selected tumors where the high-linear energy transfer (LET) benefit could be appreciated, we can participate in randomized studies. Finally, studies aimed at clarifying the usefulness of carbon ion radiotherapy and elucidating any advantages from hypo-fractionation should be considered. A multi-institutional prospective non-randomized concurrent phase II clinical trial is one such new approach, and it will be proposed not only to the Japanese, but also to the international community of particle therapy and radiation oncology.

  4. Temporary loop ileostomy: prospective study of indications and complication

    To asses the indications and complications of temporary loop ileostomy. This was a prospective cohort study conducted at Isra University Hospital, Hyderabad, Pakistan between February 2003 and August 2006. All patients who had temporary loop ileostomy during that period were included in this study. The indications and various postoperative complications were noted during postoperative hospital stay and subsequently during follow up till stoma were closed. Fifty six patients fulfilled the selection criteria during the study period. Typhoid (enteric) perforation was the most common indication of loop ileostomy accounting for about two thirds of all cases. Other indications were iatrogenic, covering ileostomy for rectal cancers, following resection anastomosis, tuberculosis, blunt abdominal trauma, anastomosis leak and rectovaginal fistula. Post operative skin excoriation was the most common complication while poor siting, transient edema, retraction and high output were other less common complications. Temporary loop ileostomy is the stoma of choice for temporary faecal diversion as most of its complications are manageable conservatively. (author)

  5. Validation of the new graded prognostic assessment scale for brain metastases: a multicenter prospective study

    Prognostic indexes are useful to guide tailored treatment strategies for cancer patients with brain metastasis (BM). We evaluated the new Graded Prognostic Assessment (GPA) scale in a prospective validation study to compare it with two published prognostic indexes. A total of 285 newly diagnosed BM (n = 85 with synchronous BM) patients, accrued prospectively between 2000 and 2009, were included in this analysis. Mean age was 62 ± 12.0 years. The median KPS and number of BM was 70 (range, 20-100) and 3 (range, 1-50), respectively. The majority of primary tumours were lung (53%), or breast (17%) cancers. Treatment was administered to 255 (89.5%) patients. Only a minority of patients could be classified prospectively in a favourable prognostic class: GPA 3.5-4: 3.9%; recursive partitioning analysis (RPA) 1, 8.4% and Basic Score for BM (BSBM) 3, 9.1%. Mean follow-up (FU) time was 5.2 ± 4.7 months. During the period of FU, 225 (78.9%) patients died. The 6 months- and 1 year-OS was 36.9% and 17.6%, respectively. On multivariate analysis, performance status (P < 0.001), BSBM (P < 0.001), Center (P = 0.007), RPA (P = 0.02) and GPA (P = 0.03) were statistically significant for OS. The survival prediction performances' of all indexes were identical. Noteworthy, the significant OS difference observed within 3 months of diagnosis between the BSBM, RPA and GPA classes/groups was not observed after this cut-off time point. Harrell's concordance indexes C were 0.58, 0.61 and 0.58 for the GPA, BSBM and RPA, respectively. Our data suggest that the new GPA index is a valid prognostic index. In this prospective study, the prediction performance was as good as the BSBM or RPA systems. These published indexes may however have limited long term prognostication capability

    Malaria is a major public health problem in Ethiopia. Over the past years, the disease has been consistently reported as the first leading cause of outpatient visits, hospitalization and death in health facilities across the country. Thus, a retrospective study was conducted to determine the prevalence of malaria from peripheral blood smear examination from the Serbo Health Center of Ethiopia. The case notes of all malaria cases treated between July 2007 and June 2008 were carefully reviewed and analyzed. Of the total 6863 smears, 3009 were found to be positive and contribute 43.8% of diagnostic yield. Plasmodium falciparum constituted the most predominant [64.6% (1946/3009 cases)], while Plasmodium vivax confirmed with 34.9% (1052/3009) cases. Among patients who underwent diagnostic testing and treatment for malaria, males [63.8% (1918/3009 cases)] were more prone to have a positive malaria smear than females [36.2% (1091/3009 cases)]. Chi-square statistical analysis shown that there was a statistically significant association found between male cases and number of positive blood smear (chi(2)=28.1; df=7; p-value=0.001). The present study results clearly suggest that the catchment area of Serbo Health Center is prone for epidemic malaria and the situation is quite deteriorating. At the moment, although we are not equipped with magic bullet for malaria effective low-cost strategies are available for its treatment, prevention, and control. Therefore, creating awareness by active health education campaigns and applying integrated malaria control strategy could bring the constructive outcome in the near future. PMID:20701879

  7. Suspended sediments and organic matter in mountain headwaters of the Amazon River: Results from a 1-year time series study in the central Peruvian Andes

    Townsend-Small, Amy; McClain, Michael E.; Hall, Bonnie; Noguera, Jorge L.; Llerena, Carlos A.; Brandes, Jay A.

    2008-02-01

    Few studies have examined the dynamics of sediments and suspended organic matter and their export from headwater basins in the Andes Mountains to the Amazon River, despite the fact that the Andes are the primary source of sediments to the lower Amazon basin. We measured river discharge as well as the concentration, δ 15N, δ 13C, %N, and %OC of coarse and fine suspended sediments (CSS and FSS) in the Chorobamba River, located in the central Andean Amazon of Peru. Samples were taken at least weekly over an entire year (July 2004-July 2005), with additional sampling during storms. Concentrations of particulate organic matter (POM) were generally low in the study river, with concentrations increasing by up to several orders of magnitude during episodic rain events. Because both overall flow volumes and POM concentrations increased under stormflow conditions, the export of POM was enhanced multiplicatively during these events. We estimated that a minimum of 80% of annual suspended sediment transfer occurred during only about 10 days of the year, also accounting for 74% of particulate organic carbon and 64% of particulate organic nitrogen transport. Significant differences occurred between seasons (wet and dry) for δ 13C of coarse and fine POM in the Chorobamba River, reflecting seasonal changes in organic matter sources. The time series data indicate that this Andean river exports approximately equal amounts of fine and coarse POM to the lower Amazon. The observation that the vast majority of sediments and associated OM exported from Andean rivers is mobilized during short, infrequent storm events and landslides has important implications for our understanding of Amazon geochemistry, especially in the face of incipient global change.

    Kidney allograft rejection can occur in clinically stable patients, but long-term significance is unknown. We determined whether early recognition of subclinical rejection has long-term consequences for kidney allograft survival in an observational prospective cohort study of 1307 consecutive nonselected patients who underwent ABO-compatible, complement-dependent cytotoxicity-negative crossmatch kidney transplantation in Paris (2000-2010). Participants underwent prospective screening biopsies at 1 year post-transplant, with concurrent evaluations of graft complement deposition and circulating anti-HLA antibodies. The main analysis included 1001 patients. Three distinct groups of patients were identified at the 1-year screening: 727 (73%) patients without rejection, 132 (13%) patients with subclinical T cell-mediated rejection (TCMR), and 142 (14%) patients with subclinical antibody-mediated rejection (ABMR). Patients with subclinical ABMR had the poorest graft survival at 8 years post-transplant (56%) compared with subclinical TCMR (88%) and nonrejection (90%) groups (P<0.001). In a multivariate Cox model, subclinical ABMR at 1 year was independently associated with a 3.5-fold increase in graft loss (95% confidence interval, 2.1 to 5.7) along with eGFR and proteinuria (P<0.001). Subclinical ABMR was associated with more rapid progression to transplant glomerulopathy. Of patients with subclinical TCMR at 1 year, only those who further developed de novo donor-specific antibodies and transplant glomerulopathy showed higher risk of graft loss compared with patients without rejection. Our findings suggest that subclinical TCMR and subclinical ABMR have distinct effects on long-term graft loss. Subclinical ABMR detected at the 1-year screening biopsy carries a prognostic value independent of initial donor-specific antibody status, previous immunologic events, current eGFR, and proteinuria.

    Full Text Available Abstract Background Low back pain (LBP and leisure time physical activity (LTPA are considered to be closely related, and clinical guidelines for the treatment of acute LBP recommend patients stay physically active. However, the documentation for this recommendation is sparse and based on studies involving patient populations. The purpose of the study was (1 to investigate the correlation between LBP and LTPA on a weekly basis over the course of a year in a high-risk group of cleaners; and (2 to investigate if maintaining LTPA during an episode of acute LBP has a positive effect on LBP intensity in the subsequent 4 weeks. Methods 188 cleaners consented to participate in a 52-week text message survey about hours of LTPA and intensity of LBP (from 0 to 9 over the previous 7 days. The correlation between LBP and LTPA was calculated by Pearson correlation coefficient. During an episode of acute LBP, a mixed effect logistic regression model was used to investigate whether cleaners who maintain LTPA have a lower pain intensity and higher probability of returning to initial pain intensity within the following four weeks compared with cleaners who decrease LTPA during acute LBP. Results The correlation between weekly LTPA and LBP data was negative, but numerically low (r = -0.069 and statistically insignificant (p = 0.08. Among the 82 cleaners experiencing at least one episode of acute LBP, those maintaining LTPA during an episode of acute LBP did not have a lower pain intensity (average LBP intensity difference between groups of 0.06; 95% confidence interval (95% CI of -0.417 to 0.539 or higher probability of returning to initial pain level (Odds ratio 1,02; 95% CI of 0.50 to 2.09 in the following four weeks compared with cleaners decreasing LTPA during acute LBP. Conclusions Hours of LTPA and intensity of LBP measured on a weekly basis throughout a year showed no close correlation. Maintaining LTPA during an episode of acute LBP did not result in a

    Full Text Available Introduction. Chronic functional instability—characterized by repeated ankle inversion sprains and a subjective sensation of instability—is one of the most common residual disabilities after an inversion sprain. However, whether surgical reconstruction improves sensorimotor control has not been reported to date. The purpose of this study was to assess functional improvement of chronic ankle instability after surgical reconstruction using the remnant ligament. Materials and Methods. We performed 10 cases in the intervention group and 20 healthy individuals as the control group. Before and after surgical reconstruction, we evaluated joint position sense and functional ankle instability by means of a questionnaire. Results and Discussion. There was a statistically significant difference between the control and intervention groups before surgical reconstruction. Three months after surgery in the intervention group, the joint position sense was significantly different from those found preoperatively. Before surgery, the mean score of functional ankle instability in the intervention group was almost twice as low. Three months after surgery, however, the score significantly increased. The results showed that surgical reconstruction using the remnant ligament was effective not only for improving mechanical retensioning but also for ameliorating joint position sense and functional ankle instability.

    Full Text Available Background: Whether Vitamin D supplementation in prediabetes subjects prevents the development of diabetes is a matter of debate, and the results are inconsistent. This open-label, randomized study in subjects with prediabetes evaluated the effect of 12 months of Vitamin D supplementation on glycemic parameters and progression of prediabetes to diabetes in an ethnically homogeneous Kashmiri population. Materials and Methods: A total of 147 subjects were diagnosed as prediabetes out of which 137 subjects were randomized to receive in addition to standard lifestyle measures, either Vitamin D 60,000 IU weekly for 4 weeks and then 60,000 IU monthly (n = 69 or no Vitamin D (n = 68. Fasting plasma glucose (FPG, 2-h plasma glucose and A1C levels were estimated at 0, 6 and 12 months. Changes in FPG, 2-h plasma glucose, A1C level and the proportion of subjects developing diabetes were assessed among 129 subjects. Results: At 12 months, A1C levels were significantly lesser (5.7% ± 0.4% in the Vitamin D supplemented group when compared with non-Vitamin D supplemented (6.0% ± 0.3%. Similarly, FPG (97 ± 7 and 2-h plasma glucose (132 ± 16 were significantly less in Vitamin D supplemented group as compared with non-Vitamin D supplemented group (FPG = 116 ± 6 and 2-h plasma glucose = 157 ± 25 at 12 months. Nine out of 65 in non-Vitamin D supplemented and seven out of 64 in the Vitamin D supplemented group developed diabetes. Conclusions: Vitamin D supplementation in prediabetes subjects significantly lowered FPG, 2-h plasma glucose and A1C levels.

    Kikoła, Daniel; Vogt, Ramona

    2011-01-01

    Collisions of deformed uranium nuclei provide a unique opportunity to study the spatial dependence of charmonium in-medium effects. By selecting the orientations of the colliding nuclei, different path lengths through the nuclear medium could be selected within the same experimental environment. In addition, higher energy densities can be achieved in U+U collisions relative to Au+Au collisions. In this paper, we investigate the prospects for charmonium studies with U+U collisions. We discuss the effects of shadowing and nuclear absorption on the J/\\psi\\ yield. We introduce a new observable which could help distinguish between different types of J/\\psi\\ interactions in hot and dense matter.

    This study examines the independent impact of bullying on suicide risk. Bullying was assessed by peer nomination in a prospective study of 1,655 7th and 8th grade Korean students, and suicide by youth self-report. Odds Ratios (ORs) of bullying for suicidal risks were computed, controlling for other suicide risk factors. Victim-Perpetrators and female Victims at baseline showed increased risk for persistent suicidality (OR: 2.4-9.8). Male Incident Victims exhibited increased risk for suicidal behaviors and ideations (OR = 4.4, 3.6). Female Persistent Perpetrators exhibited increased risks for suicidal behaviors; male Incident Perpetrators had increased risk for suicidal ideations (OR = 2.7, 2.3). Baseline-only male Victim-Perpetrators showed increased risk for suicidal ideations. (OR = 6.4). Bullying independently increased suicide risks. PMID:19123106

  5. Protective environment for marrow transplant recipients. A prospective study

    Laminar air flow isolation and decontamination procedures were evaluated in a prospective randomized study in patients with aplastic anemia or acute leukemia undergoing marrow transplantation from HLA-matched siblings. Patients transplanted in the laminar air flow group had significantly less septicemia and major local infections than did patients in the control group. Nineteen of 46 laminar air flow patients and six of 44 control patients are alive at present. In patients with aplastic anemia the survival was 13 of 17 in the laminar air flow group compared with four of 17 in the control group. In patients with acute leukemia the survival was six of 29 in the laminar air flow group versus two of 27 in the control group. These differences were not statistically significant. Death in both the laminar air flow and control groups was predominantly due to interstitial pneumonitis or recurrent leukemia, which were unaffected by isolation and decontamination

  7. Prospective study on microscopic potential with Gogny interaction

    We present our current studies and future plans on microscopic potential based on effective nucleon-nucleon interaction and many-body theory. This framework treats in an unified way nuclear structure and reaction. It offers the opportunity to link the underlying effective interaction to nucleon scattering observables. The more consistently connected to a variety of reaction and structure experimental data the framework is, the more constrained the effective interaction will be. As a proof of concept, we present some recent results for both neutron and proton scattered from spherical target nucleus, namely 40Ca, using the Gogny D1S interaction. Possible fruitful cross-talks between microscopic potential, phenomenological potential and effective interaction are exposed. We then draw some prospective plans for the forthcoming years including scattering from spherical nuclei experiencing pairing correlations, scattering from axially deformed nuclei, and new effective interaction with reaction constraints.

    2012-12-01

    Full Text Available Background: Hysteroscopy is the gold standard procedure for uterine cavity exploration. However, hysteroscopy is only recommended by the WHO when clinical or complementary exams (ultrasound, HSG suggest intrauterine abnormality or after in vitro fertilization failure. Nevertheless, many specialists feel that hysteroscopy is a more accurate tool. The aim of this prospective study is to assess the value of diagnostic hysteroscopy in a primary workup of infertility by describing hysteroscopy findings in a population of 324 infertile patients during 18 months (December 2010 - May 2012. Methods: We analysed prospectively 324 infertile patients in gynaecology OT setting. Diagnostic video-assisted hysteroscopy was performed using a flexible hysteroscope. Hysteroscopy was performed with a standard sequence, inspecting the endocervical canal, uterine cavity, endometrium, and tubal ostia and findings recorded. Results: Hysteroscopy was normal in 65.12% of patients. Cervico-isthmic abnormalities were present in 6.48% of patients with cervical stenosis being the major abnormality. Uterine cavity was normal in 86% of patients. Observed abnormalities were septate uterus in 10 cases, intrauterine synechiae in 16 cases, sub mucus myoma in 2 cases, deformed cavity in 10 cases and endometrial polyp in 2 cases. Ostial fibrosis was observed in 29 patients. Endometrial abnormalities (fibrosis, inflammation were observed in 30 patients. Seven patients turned out to be of genital tuberculosis with endometrial biopsy. No significance was found regarding the total number of intrauterine pathologies when comparing the groups of primary versus secondary infertility. Conclusions: Rates of abnormal findings in infertile patient who underwent diagnostic hysteroscopy was 34.88% in our study. Our data are an additional argument to suggest hysteroscopy as part of investigation in infertile woman. Routine diagnostic hysteroscopy should be part of an infertility workup in primary

    Full Text Available Izabela Kozicka, Tomasz Kostka Department of Geriatrics, Medical University of Lodz, Lodz, Poland Purpose: To assess the relative role of handgrip strength (HGS, quadriceps muscle power (Pmax, and optimal shortening velocity (υopt in maintaining functional abilities (FAs in older adults living in a long-term care home over a 1-year follow-up. Subjects and methods: Forty-one inactive older institutionalized adults aged 69.8±9.0 years participated in this study. HGS, Pmax, υopt, cognitive function using the Mini-Mental State Examination, depressive symptoms using the Geriatric Depression Scale, nutritional status using the Mini Nutritional Assessment (MNA, and physical activity (PA using the Seven-Day Physical Activity Recall Questionnaire were assessed at baseline and at 1-year follow-up. FAs were assessed with activities of daily living (ADL, instrumental ADL, and Timed Up & Go test. Results: Both at baseline and at follow-up, FAs were related to age, HGS, Pmax/kg, υopt, MNA, and PA. These associations were generally similar in both sexes. As revealed in multiple regression analysis, υopt was the strongest predictor of FA, followed by Pmax/kg, PA, and MNA. FA deteriorated after 1 year as measured by ADL and Timed Up & Go test. Pmax and υopt, but not HGS, also decreased significantly after 1 year. Nevertheless, 1-year changes in FAs were not related to changes in HGS, Pmax, υopt, or PA. Conclusion: The 1-year period of physical inactivity among older institutionalized adults was found to have a negative effect on their FAs, Pmax, and υopt. The present study demonstrates that Pmax and, especially, υopt correlated with FAs of older adults more than HGS, both at baseline and at follow-up. Despite this, 1-year natural fluctuations of PA, Pmax, and υopt are not significant enough to influence FAs in inactive institutionalized older adults.

    The majority of U.S. parents spank their children, often beginning when their children are very young. We examined families (N=2,788) who participated in a longitudinal community-based study of new births in urban areas. Prospective analyses examined whether spanking by the child's mother, father, or mother's current partner when the child was 1-year-old was associated with household CPS involvement between age 1 and age 5. Results indicated that 30% of 1-year-olds were spanked at least once in the past month. Spanking at age 1 was associated with increased odds of subsequent CPS involvement (adjusted odds ratio=1.36, 95% CI [1.08, 1.71], ppunishment, professionals who work with families should counsel parents not to spank infants and toddlers. For optimal benefits, efforts to educate parents regarding alternative forms of discipline should begin during the child's first year of life. PMID:24602690

    Purpose. Rhabdomyolysis (RML) following cardiac surgery and its relationship with acute kidney injury (AKI) require investigation. Patients and Methods. All patients undergoing cardiac surgery in our hospital were enrolled in this prospective study during a 1-year period. To investigate the occurrence of RML and its association with AKI, all patients in the study underwent serial assessment of serum creatine kinase (CK) and myoglobin levels. Serial renal function, prior statin treatment, and outcome variables were recorded. Results. In total, 201 patients were included in the study: 185 men and 16 women with a mean age of 52.0 ± 12.4 years. According to the presence of RML (CK of ≥2,500 U/L), the patients were divided into Group I (RML present in 17 patients) and Group II (RML absent in 184 patients). Seven patients in Group I had AKI (41%) where 34 patients in group II had AKI (18.4%), P = 0.025. We observed a significantly longer duration of ventilation, length of stay in the ICU, and hospitalization in Group I (P < 0.001 for all observations). Conclusions. An early elevation of serum CK above 2500 U/L postoperatively in high-risk cardiac surgery could be used to diagnose RML that may predict the concomitance of early AKI. PMID:27034948

  17. A prospective study of the development of hand eczema in an automobile manufacturing industry.

    Kristensen, O

    1992-05-01

    We have not been able to find any prospective study of the risk of developing occupational dermatitis in the car manufacturing industry. To try to define individual predictive risk factors for the development of hand eczema and to determine the prevalence of hand eczema within 1 year in an automobile manufacturing industry, we investigated prospectively 1564 new employees during one year of employment. Only persons with previous atopic dermatitis or hand eczema were restricted to dry and clean workplaces. The employees were personally interviewed and examined before their employment. Written questionnaires were used at 3 and 12 months to obtain information on type of work, exposure, protection and hand dermatitis. All patients developing hand eczema were examined, patch tested and followed to determine the course and consequence of their eczema. The risk turned out to be only 4% on average, but significantly higher in females (6%). Certain sections within the factory such as wet work (canteen/kitchen and cleaning) and work in the paint shop with high exposure to organic solvents carried significantly higher risks. Heavy exposure to mineral oil, a known risk factor, was effectively counteracted by the extensive use of protective gloves to yield a lower than average prevalence in the press and body shop. Individual risk factors for the development of hand eczema were previous hand eczema, atopic dermatitis, but also wool intolerance and hay fever as isolated phenomena. Most cases of hand eczema were mild, of irritant contact type and only 1 employee developed an allergic contact dermatitis due to the working environment.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1395598

    On the recommendation of several studies, carotid endarterectomy (CEA) should be delayed for at least 6 weeks in patients suffering an acute nondisabling stroke. Our objective was to determine if these patients could be safely operated on earlier, thus decreasing the risk of a recurrent stroke prior to surgery. This prospective study, carried out from January 1990 to December 1997, included 72 consecutive patients having a nondisabling hemispheric stroke with severe ipsilateral carotid stenosis (NASCET 70-99%). All patients underwent CEA within 15 days of stroke onset. Patients were considered to have a nondisabling hemispheric stroke if (1) symptoms of hemispheric ischemia persisted longer than 24 hr and (2) the resulting deficit caused no major impairment in their everyday activities. All patients were examined by a neurologist prior to carotid angiography and contrast CT scan. Hemorrhage seen on the initial CT scan eliminated the patient from the study. If the CT scan with contrast injection was negative, patients underwent magnetic resonance imaging. CEA was performed under general anesthesia with intraluminal shunting. All patients had a postoperative duplex scan and yearly follow-up by a neurologist and a surgeon, with a duplex scan of the carotid arteries. Mean follow-up was 53 months. Our study shows that CEA can be performed relatively safely within 15 days following an acute nondisabling stroke. The arbitrary 6-week delay for CEA may unnecessarily expose patients with high-grade stenosis to a recurrent stroke, which could be prevented by earlier surgery. PMID:10629271

  1. Screening for vulnerability in older cancer patients: the ONCODAGE Prospective Multicenter Cohort Study.

    Pierre Soubeyran

    Full Text Available Geriatric Assessment is an appropriate method for identifying older cancer patients at risk of life-threatening events during therapy. Yet, it is underused in practice, mainly because it is time- and resource-consuming. This study aims to identify the best screening tool to identify older cancer patients requiring geriatric assessment by comparing the performance of two short assessment tools the G8 and the Vulnerable Elders Survey (VES-13.The diagnostic accuracy of the G8 and the (VES-13 were evaluated in a prospective cohort study of 1674 cancer patients accrued before treatment in 23 health care facilities. 1435 were eligible and evaluable. Outcome measures were multidimensional geriatric assessment (MGA, sensitivity (primary, specificity, negative and positive predictive values and likelihood ratios of the G8 and VES-13, and predictive factors of 1-year survival rate.Patient median age was 78.2 years (70-98 with a majority of females (69.8%, various types of cancer including 53.9% breast, and 75.8% Performance Status 0-1. Impaired MGA, G8, and VES-13 were 80.2%, 68.4%, and 60.2%, respectively. Mean time to complete G8 or VES-13 was about five minutes. Reproducibility of the two questionnaires was good. G8 appeared more sensitive (76.5% versus 68.7%, P =  0.0046 whereas VES-13 was more specific (74.3% versus 64.4%, P<0.0001. Abnormal G8 score (HR = 2.72, advanced stage (HR = 3.30, male sex (HR = 2.69 and poor Performance Status (HR = 3.28 were independent prognostic factors of 1-year survival.With good sensitivity and independent prognostic value on 1-year survival, the G8 questionnaire is currently one of the best screening tools available to identify older cancer patients requiring geriatric assessment, and we believe it should be implemented broadly in daily practice. Continuous research efforts should be pursued to refine the selection process of older cancer patients before potentially life-threatening therapy.

    1990-01-01

    Despite the high prevalence of psychic symptoms in lupus patients, there are few systematic studies in this area. Through a multidisciplinary approach, the authors developed a prospective study to characterize and correlate psychopathological aspects with clinical and laboratory data concerning neural manifestations of the disease. Out of 23 patients studied, 12 showed psychic alterations, which were interpreted as primary manifestations of the disease. All of them presented organic mental syndromes (DSM-III-R) in which cognitive symptoms were the most prominent, followed by affective, catatonic and hallucinatory features. The neurologic findings (seizure, migraine and muscular atrophy), as well as the ophthalmologic alterations (hemorrhage and soft exudates) were frequent and concomitant with the psychic features. The laboratory findings were: LE cells 50%; anti-Sm: 16%; anti-U1 RNP: 50%; anti-Ro/SS-A: 50%; anti-nDNA: 58%; decreased CH50 or fractions (C3, C4): 67%; anti-P: 18%; antigangliosides IgG: 67%; antigangliosides IgM: 78%. The cerebrospinal fluid analysis showed: increased cellularity: 18%; elevated protein: 36%; antigangliosides IgG: 67%; antigangliosides IgM: 33%; immunocomplexes: 36%. In spite of the absence of an adequate control group and of the small number of patients, the multidisciplinary approach leads to a better characterization of the nervous system involvement in this disease.

    The Purpose of this study was to evaluate the sexual function after partial penectomy for penile carcinoma patients. Between January 2010 and May 2013, patients treated with partial penectomy at our institution were prospectively enrolled in this study. Sexual function (IIEF-15), age, body mass index, penile length in the flaccid state after partial penectomy (PL), treatment, having a partner and psychological factors (SAS scores and SDS scores) were assessed. Univariate and multivariate linear regression analyses were performed. 43 patients were included in our study. The median age was 56 years, and the median PL was 4 cm. The preoperative IIEF-15, SAS, SDS scores were significantly different from the postoperative scores. There was no statistically significant difference between the patients treated with partial penectomy and partial penectomy+ lymphadenectomy on IIEF-15 scores. Age was negatively associated with erectile function, sexual desire, and overall satisfaction; PL was positively associated with intercourse satisfaction; SAS score was negatively associated with erectile function, orgasmic function, sexual desire, and intercourse satisfaction. Our preliminary findings suggest that the sexual function after partial penectomy was significantly reduced. The sexual function was negatively affected by age and anxiety but positively affected by PL. PMID:26902397

  4. Prospective study of nutritional support during pelvic irradiation

    A prospective study of nutritional support during pelvic irradiation was carried out in 32 patients with a primary pelvic malignancy and prior weight loss. Both curative and palliative patients were eligible for the study. Seventeen patients were randomized to receive intravenous hyperalimentation (IVH) and fifteen patients served as controls who were maintained on their regular diet. Patients were stratified by percent body weight loss. Tolerance to therapy was assessed by evaluation of functional status and by using nutritional parameters of body weight change, change in serum protein levels, and response to delayed hypersensitivity skin tests. The curative IVH group tolerated therapy well by both functional and nutritional measurements. All curative IVH patients completed the planned radiation therapy without a treatment break and were fully active following treatment. Patients gained an average of 4.0 kg body weight during irradiation, which was significantly different from the curative control patients. They demonstrated a significant increase in serum transferrin reflecting an improvement in visceral protein. In addition, all showed a positive response to delayed hypersensitivity skin tests at the completion of irradiation. The palliative IVH patients often did poorly because of progression of disease and demonstrated only an elevation of serum transferrin during treatment. The results in the curative IVH group suggest a potential adjunctive role for intravenous hyperalimentation in the malnourished cancer patient undergoing pelvic irradiation. Clearly, further study of nutritional support during pelvic irradiation is needed using curative patients with a single tumor type and significant prior weight loss

    2008-03-01

    Full Text Available Abstract Background Surgical site infections (SSI remain a major clinical problem in terms of morbidity, mortality, and hospital costs. Nearly 60% of SSI diagnosis occur in the postdischarge period. However, literature provides little information on risk factors associated to in-hospital and postdischarge SSI occurrence. A national prospective multicenter study was conducted with the aim of assessing the incidence of both in-hospital and postdisharge SSI, and the associated risk factors. Methods In 2002, a one-month, prospective national multicenter surveillance study was conducted in General and Gynecological units of 48 Italian hospitals. Case ascertainment of SSI was carried out using standardized surveillance methodology. To assess potential risk factors for SSI we used a conditional logistic regression model. We also reported the odds ratios of in-hospital and postdischarge SSI. Results SSI occurred in 241 (5.2% of 4,665 patients, of which 148 (61.4% during in-hospital, and 93 (38.6% during postdischarge period. Of 93 postdischarge SSI, sixty-two (66.7% and 31 (33.3% were detected through telephone interview and questionnaire survey, respectively. Higher SSI incidence rates were observed in colon surgery (18.9%, gastric surgery (13.6%, and appendectomy (8.6%. If considering risk factors for SSI, at multivariate analysis we found that emergency interventions, NNIS risk score, pre-operative hospital stay, and use of drains were significantly associated with SSI occurrence. Moreover, risk factors for total SSI were also associated to in-hospital SSI. Additionally, only NNIS, pre-operative hospital stay, use of drains, and antibiotic prophylaxis were associated with postdischarge SSI. Conclusion Our study provided information on risk factors for SSI in a large population in general surgery setting in Italy. Standardized postdischarge surveillance detected 38.6% of all SSI. We also compared risk factors for in-hospital and postdischarge SSI

    Travel-related poisoning is an emerging social and public health emergency in Bangladesh but its cause and significance have not been determined. To investigate this syndrome we performed a prospective clinical study and retrospective analysis of hospital records in a general medicine unit of a public tertiary care teaching hospital in Dhaka, Bangladesh, using toxicological analysis by fluorescence polarization immunoassay (FPIA) and liquid chromatography coupled to time-of-flight mass spectrometry (LC-TOF MS). The participants of the prospective study were 130 consecutive patients aged 16-80 years who were admitted with central nervous system depression (Glasgow Coma Score 3-14) after using public transportation, in the absence of other abnormalities, from January through June 2004, and a convenience sample of 15 such patients admitted during 3 days in May 2006. In 2004-2006, travel-related poisoning increased from 6.1 to 9.5% of all admissions (210-309 of 3266-3843 per year), representing 46.6-55.7% of all admitted poisoning cases. Incidents were associated with bus (76%), taxi, train, and air travel, or local markets; 98% of patients remembered buying or accepting food or drinks before losing consciousness. Direct financial damage (missing property) was diverse and frequently existential. Among 94 urine samples analyzed by FPIA, 74% tested positive for benzodiazepines. Among 15 urine samples analyzed by LC-TOF MS, lorazepam was detected in all; five also contained diazepam or metabolites; nitrazepam was present in three. FPIA results obtained for these 15 samples were below the recommended cut-off in eight (53%; lorazepam only). Our findings show that the massive medicosocial emergency of travel-related poisoning in Bangladesh is the result of drug-facilitated organized crime and that benzodiazepine drugs are used to commit these crimes, suggesting modifications to the local emergency management of the victims of this type of poisoning. They also highlight the

    Full Text Available Objective: To evaluate five biomarkers (neopterin, vascular endothelial growth factor-A, thrombomodulin, soluble vascular cell adhesion molecule 1 and pentraxin 3 in differentiating clinical dengue cases. Methods: A prospective cohort study was conducted whereby the blood samples were obtained at day of presentation and the final diagnosis were obtained at the end of patients’ follow-up. All patients included in the study were 15 years old or older, not pregnant, not infected by dengue previously and did not have cancer, autoimmune or haematological disorder. Median test was performed to compare the biomarker levels. A subgroup Mann-Whitney U test was analysed between severe dengue and non-severe dengue cases. Monte Carlo method was used to estimate the 2-tailed probability (P value for independent variables with unequal number of patients. Results: All biomarkers except thrombomodulin has P value < 0.001 in differentiating among the healthy subjects, non-dengue fever, dengue without warning signs and dengue with warning signs/severe dengue. Subgroup analysis for all the biomarkers between severe dengue and non-severe dengue cases was not statistically significant except vascular endothelial growth factor-A (P < 0.05. Conclusions: Certain biomarkers were able to differentiate the clinical dengue cases. This could be potentially useful in classifying and determining the severity of dengue infected patients in the hospital.

    Full Text Available Abstract Background Achalasia is a well-characterized esophageal motor disorder but the rarity of the disease limits performing large studies on its demographic and clinical features. Methods Prospectively, 213 achalasia patients (110 men and 103 women were enrolled in the study. The diagnosis established by clinical, radiographic, and endoscopic as well as manometry criteria. All patients underwent a pre-designed clinical evaluation before and within 6 months after the treatment. Results Solid dysphagia was the most common clinical symptom in men and women. Chest pain was the only symptom which was significantly different between two groups and was more complained by women than men (70.9% vs. 54.5% P value= 0.03. Although the occurrence of chest pain significantly reduced after treatment in both groups (P Conclusion It seems that chest pain is the distinct symptom of achalasia which is affected by sex as well as age and does not relate to the duration of illness, LESP and the type of treatment achalasia patients receive.

  12. Gamma Knife Treatment of Growing Vestibular Schwannoma in Norway: A Prospective Study

    Purpose: Gamma Knife radiosurgery (GKRS) has been increasingly used in the treatment of vestibular schwannoma (VS). Very few studies relate tumor control and post-treatment growth rates to pretreatment growth rates. Methods and Materials: We prospectively included 45 consecutive VS patients who were initially treated conservatively and then received GKRS between 2000 and 2007 because of demonstrated tumor growth. Pretreatment and post-treatment tumor volumes were estimated. Patients underwent audiograms, reported their symptoms, and responded to the Short Form General Health Survey (SF-36) questionnaire on each visit. Results: Volume doubling times before and after treatment were 1.36 years (95% confidence intervals, 1.14-1.68) and −13.1 years (95% confidence intervals, −111.0 to −6.94), respectively. Tumor control, defined as a post-GKRS growth rate ≤0, was achieved in 71.1% of patients, with highest odds for tumor control among older patients and those with larger tumors. The 5-year retreatment-free survival rate was 93.9% (95% confidence intervals, 76.5-98.5). None of the clinical endpoints investigated showed statistically significant changes after GKRS, but improvement was seen in a few SF-36 parameters. Conclusions: GKRS alters the natural course of the tumor by reducing growth. Mathematic models yield poorer tumor control rates than those found by clinical assessment. Symptoms were unaffected by treatment, but quality of life was improved.

    2016-06-01

    OBJECT Current recommendations stress the need for cognitive parameters to be integrated in the evaluation of outcomes for intracranial meningioma surgery. The aim of this prospective study was to examine neurocognitive function in meningioma patients pre- and postoperatively. METHODS Patients with skull base (anterior and middle fossa) and convexity (anterior and posterior) meningiomas (n = 54) underwent neuropsychological examination prior to and 1 year after surgery. A control group (n = 52) of healthy volunteers matched for age, sex, and education underwent the same examination. Assessments included executive, memory, and motor functions with standardized testing. Patients with convexity meningiomas were clinically assessed for parietal association cortex functions. RESULTS All patients performed significantly worse (p 4 cm) had more severe neurocognitive deficits than those with a small tumor (< 4 cm). Postoperatively, patients showed no deterioration in neurocognitive function. Instead, significant improvement (p < 0.05) was observed in some executive, motor, and parietal association cortex functions. CONCLUSIONS According to the authors' findings, intracranial meningiomas may cause neurocognitive deficits in patients. Surgery does not cause a deterioration in cognitive function; instead, it may lead to improvements in some functions. Permanent neuropsychological postoperative deficits should be interpreted as tumor-induced rather than due to surgery. PMID:26636380

    Herpes simplex virus (HSV) is one of the most commonly identified infectious aetiologies of encephalitis in North America and Europe. The epidemiology of encephalitis beyond these regions, however, is poorly defined. During 2009-2012 we enrolled 313 patients in a multicentre prospective study of encephalitis in Peru, 45 (14·4%) of whom had confirmed HSV infection. Of 38 patients with known HSV type, 84% had HSV-1 and 16% had HSV-2. Patients with HSV infection were significantly more likely to present in the summer months (44·4% vs. 20·0%, P = 0·003) and have nausea (60·0% vs. 39·8%, P = 0·01) and rash (15·6% vs. 5·3%, P = 0·01) compared to patients without HSV infection. These findings highlight differences in the epidemiology and clinical presentation of HSV encephalitis outside of the Northern Hemisphere that warrant further investigation. Furthermore, there is an urgent need for improved HSV diagnostic capacity and availability of intravenous acyclovir in Peru. PMID:26733400

  1. Prospective study of adverse reaction to intravenous administered contrast media

    This is a prospective study of the incidence of adverse reaction in those patients who accepted the intravenous urography (IVU) and enhanced computerized tomography (CT) at our hospital from September 1986 to January 1988. Of 7107 patients examined, complete records are available for 6917 (male 3760, female 3157). A record form of adverse reactions was constructed based on the symptoms reported by Ansell. Since some adverse reactions may occur with their own specific mechanism, they are sub-divided into four groups (physic, chemical toxic. Allergic and those that may involve multiple mechanisms are grouped as ''others'') according to the Felder's classification presented in the discussion. There was no record of the reactions belonging to the chemical toxic mechanism. The total incidence of the other groups are 82.4 % for physic, 4.8 % for allergic, 5.8 % for ''others'' and without any case of death. Two low-osmolality contrast media (LOCM) have significant lower incidence of adverse reaction than three high-osmolality contrast media (HOCM). Between two LOCM. Omnipaque is significant lower than Iopamiron in the incidence of either groups of mechanism (p < 0.01). Each LOCM and HOCM gives the same age distribution spectra of the incidence as reported, but the former have significant lower incidence of the adverse reaction than the latter. These results suggest that the LOCM may have a specific characteristics of the chemical property to induce the adverse reactions. (author)

    AIM: To evaluate the preliminary effects of comprehensive prevention of gastric cancer in Zhuanghe County epidemiologically.METHODS: Stratified sampling and cluster sampling were applied to define the intervention group and the control group. The prospective cohort study was used for evaluating the effect of preventing gastric cancer. The relative risk (RR)and attributable risk percent (AR %) of intervention on gastric cancer death were calculated. Potential years of life lost (PLYY) of the disease was analyzed, and the RR and AR %of PYLL were calculated. Survival analysis was applied among the screened patients.RESULTS: In the first 4 years after intervening, the relative risk (RR) of intervention on death was 0.5059 (95 % CI:0.3462~0.7392,P<0.05) with significance statistically. AR %of the intervention on death was 49.41%. The RR of intervention on cumulative PYLL was 0.6778 (95 % CI:0.5604~0.8198,P<0.05) with statistic significance. AR %of the intervention on cumulative PYLL was 30.32 %. The four-year survival rate of the screened patients was 0.6751(95 % CI: 0.5298~0.9047).CONCLUSION: The initiative intervention results showed that the intervention approach used in the trial was effective, it reduced mortality and increased survival rate, and alleviated the adverse effect of gastric cancer on the health and life of screened population.

    2014-03-01

    Full Text Available Introduction: Vocal cord paralysis is a common symptom of numerous diseases and it may be due to neurogenic or mechanical fixation of the cords. Paralysis of the vocal cords is just a symptom of underlying disease in some cases; so, clinical diagnosis of the underlying cause leading to paralysis of the vocal cords is important. This study evaluates the causes of vocal cord paralysis.Methods: In a prospective study, 45 patients with paralyzed vocal cord diagnosis were examined by tests such as examination of the pharynx, larynx, esophagus, thyroid, cervical, lung, and mediastinum, brain and heart by diagnostic imaging to investigate the cause vocal cord paralysis. The study was ended by diagnosing the reason of vocal cord paralysis at each stage of the examination and the clinical studies.Results: The mean duration of symptoms was 18.95±6.50 months. The reason for referral was phonation changes (97.8% and aspiration (37.8% in the subjects. There was bilateral paralysis in 6.82%, left paralysis in 56.82% and right in 63.36% of subjects. The type of vocal cord placement was midline in 52.8%, paramedian in 44.4% and lateral in 2.8% of the subjects. The causes of vocal cords paralysis were idiopathic paralysis (31.11%, tumors (31.11%, surgery (28.89%, trauma, brain problems, systemic disease and other causes (2.2%.Conclusion: An integrated diagnostic and treatment program is necessary for patients with vocal cord paralysis. Possibility of malignancy should be excluded before marking idiopathic reason to vocal cord paralysis.

    Full Text Available Abstract Background We have previously studied prospective associations between computer use and mental health symptoms in a selected young adult population. The purpose of this study was to investigate if high computer use is a prospective risk factor for developing mental health symptoms in a population-based sample of young adults. Methods The study group was a cohort of young adults (n = 4163, 20–24 years old, who responded to a questionnaire at baseline and 1-year follow-up. Exposure variables included time spent on computer use (CU in general, email/chat use, computer gaming, CU without breaks, and CU at night causing lost sleep. Mental health outcomes included perceived stress, sleep disturbances, symptoms of depression, and reduced performance due to stress, depressed mood, or tiredness. Prevalence ratios (PRs were calculated for prospective associations between exposure variables at baseline and mental health outcomes (new cases at 1-year follow-up for the men and women separately. Results Both high and medium computer use compared to low computer use at baseline were associated with sleep disturbances in the men at follow-up. High email/chat use was negatively associated with perceived stress, but positively associated with reported sleep disturbances for the men. For the women, high email/chat use was (positively associated with several mental health outcomes, while medium computer gaming was associated with symptoms of depression, and CU without breaks with most mental health outcomes. CU causing lost sleep was associated with mental health outcomes for both men and women. Conclusions Time spent on general computer use was prospectively associated with sleep disturbances and reduced performance for the men. For the women, using the computer without breaks was a risk factor for several mental health outcomes. Some associations were enhanced in interaction with mobile phone use. Using the computer at night and consequently losing

    2014-06-01

    Full Text Available OBJECTIVE: To study the age and sex incidence, various factors leading to incisional hernia, methods to control them and various types of surgical repair by mesh and their complications. BACKGROUND DATA: Incisional hernia is a common surgical condition with a reported incidence of 5-11% of patients subjected to abdominal operations. Many factors are associated with incisional hernia like age, sex, obesity, chest infections, type of suture material, type of incision and most important wound infection. All of them present a challenging problem to the surgeon. So this study has been undertaken to assess the magnitude of this condition and different modalities in surgical repair by mesh in our setup. MATERIALS & METHODS: This is a prospective study of 70 cases of incisional hernia who attended to OPD and emergency department of Sri B. M. Patil medical college Hospital & Research Centre from March 2012 to March 2014. Data were collected from the patients ie, clinical history, examination and appropriate investigations. Documentations of patients which include identification, history, clinical finding, investigative tests, operation findings, operative procedures and complications during the stay in hospital and during subsequent follow up period, were all recorded in a proforma specially prepared. RESULTS: In our series of 70 patients, clinical details of 70 patients were available. Females (80%, n=48 out- numbered males (20%, n=12 and the highest incidence was in the age group of 30 to 60 years with mean age of 45 years. Gynecological operation accounted for 73.3% (n=50 of the index operations, with lower midline incision resulting in 53.3%(n=44 of the incisional hernias. The polypropylene mesh placed overlay or inlay method. All patients attended our follow up ranging from 3 months to 2 year. Two recurrences were noticed in inlay mesh repair group. CONCLUSION: Based on our analysis, we believe that overlay mesh repair is superior to inlay mesh

    2015-01-01

    PROSPECT, the Precision Reactor Oscillation and Spectrum Experiment, will use two segmented detectors positioned 7-20 m from the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory to measure the U-235 antineutrino spectrum and perform a search for short-baseline oscillations as a signature of eV-scale sterile neutrinos. PROSPECT has developed Li-6 loaded liquid scintillator detectors for efficient identification of reactor antineutrinos and has measured reactor and cosmogenic backgrounds in the HFIR reactor building. Multiple test detectors have been built, operated, and characterized at HFIR and elsewhere to understand the optical performance of the scintillator and pulse-shape discrimination capabilities for enhanced background rejection. The results from this R&D effort are discussed, in the context of the design and physics potential of PROSPECT.

    2010-03-01

    Full Text Available Purpose Taekwondo, as the most popular martial art among Iranian sportsmen, might lead to injury for the athletes of this sport during competitions. We decided to report the incidence rate of injuries sustained by the athletes of this sport during national competitions. Methods All competitions of Iran national championship taekwondo league in 2006-2007 with 204 athletes were observed prospectively to detect the occurrence of injuries. The severity of injuries was classified into four groups (mild, moderate, severe, and critical according to the involvement of medical care team in the contest, ability of the athletes to resume and duration of probable absence of injured athletes from future competitions and training sessions. Athlete-Exposure (A-E was defined as the number of competitions multiplied by two. On this base, the rate of injury incidence per 1000 A-Es, the rate of injuries per time unit and the rate of injury occurred for each 100 athletes were considered as the major outcomes of this study. Results Of totally 1,338 A-Es, 93 injuries were recorded during the competitions. The rate of injury incidence was found to be 69.5 injuries per 1000 A-Es and the rate of injuries per minute of competitions was 0.023 which corresponded to 23.3 injuries per 1000 minutes of competitions. 45.6 injuries were occurred for each 100 athletes during the course of competitions. The most frequent injuries were mild (68.8% and critical injuries (24.7%, followed by moderate and severe injuries; 4.3% and 2.1%, respectively. Conclusion The rate of injury we found was lower than that of western countries. In spite of finding the lower limbs as the most frequent place of injuries in other studies, we found the upper limbs as the most predisposed place of injuries which might be due to difference in the method of combat of Iranian athletes with other athletes.

    Turhan Kara

    2014-12-01

    Full Text Available Background and objectives: Acetylcholinesterase inhibitors may cause postoperative residual curarization when they are used for reversal of neuromuscular blockade. Sugammadex reverses neuromuscular blockade by chemical encapsulation and is not associated with the side effects that may occur with the use of anticholinesterase agents. Because of increased outpatient surgical procedures postoperative residual curarization and rapid postoperative recovery have a greater importance in the pediatric patient population. The aim of this study was to compare the efficacy of sugammadex and neostigmine on reversing neuromuscular blockade in pediatric patients undergoing outpatient surgical procedures. Methods: 80 patients, aged 2-12 years, scheduled for outpatient surgery were enrolled in this randomized prospective study. Neuromuscular blockade was achieved with 0.6 mgkg−1 rocuronium and monitorized with train-of-four. Group RN (n = 40 received 0.03 mgkg−1 neostigmine, Group RS (n = 40 received 2 mgkg−1 sugammadex for reversal of rocuronium. Extubation time (time from the reversal of neuromuscular blockade to extubation, train-of-four ratio during this time, time to reach train-of-four > 0.9, and probable complications were recorded. Results: There was no significant difference between the patients' characteristics. Extubation time and time to reach train-of-four > 0.9 were significantly higher in Group RN (p = 0.001, p = 0.002. Train-of-four at the time of neostigmine/sugammadex injection in Group RN were significantly higher than in the RS group (p = 0.020. Extubation train-of-four ratio was significantly lower in Group RN (p = 0.002. Conclusion: Sugammadex provides safer extubation with a shorter recovery time than neostigmine in pediatric patients undergoing outpatient surgical procedures.

    1993-11-01

    In one year 715 soccer injuries were registered and treated in the casualty ward of Randers City Hospital. We conducted a prospective study of these patients, using a questionnaire in order to determine the most common locations, types, mechanisms and treatments of injury. Financial costs to society and the individual were also examined. Finally, we compared the most common types of injury definition in sports medicine. According to the Abbreviated Injury Scale, A.I.S., 44% of the injuries were classified as minor, 46% as moderate injury and 9% as severe. Fractures accounted for 17% of all injuries. Sprains and contusions were the most frequent injuries, accounting for 46% and 25% respectively. Most injuries (63%) were treated in the casualty ward, whilst 20% were treated as outpatients. 7% were admitted to the hospital immediately, and a further 2% were later admitted from the outpatient clinic. A total of 88% of those hospitalized were treated as inpatients for 1-7 days, and 12% for more than two weeks. 31% of all the soccer players seen in the casualty ward were absent from work, and 12% were absent from work for more than three weeks. 8% of the injured soccer players suffered loss of income. 40% had financial losses between $0-250, 40% between $250-750, seven per cent between $750-1,250, and 14% more than $1,250. From the data presented in this study, we conclude that the injury rate among soccer players increases with age, and the severity of the injuries is greatest in the oldest age groups. Soccer injuries constitute the major part of sports injuries seen in the casualty ward.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8256352

  14. A prospective study of radioimmunoscintigraphy in ovarian cancer

    The aim of this first prospective study using a monoclonal antibody labelled with I-123 was to determine its clinical potential. 30 patients with pelvic tumour, diagnosis known only to the gynaecological oncologists were referred and imaged at 10 min, 4h and 22h using human milk fat globule monoclonal antibody HMFG2 labelled using the iodogen technique with pure I-123 (2.5mCi injected). Images were reported without clinical information as negative or positive for ovarian cancer OC and its distribution mapped. Surgery and histology were assessed independently by the oncologists and the patients finally classified into group I: 10 with benign or non ovarian malignant disease and group II: 20 with OC in whom the sites of biopsy positive disease were also mapped. In group 1 5/10 patients showed the pattern of OC indicating that the technique is unsuccessful as a screening test due to the lack of specificity - uptake by liver, stomach and colon metastases being seen. In group II the distribution of OC primary and metastases was correct in 18/20, 90%. A new technique based on the kinetics of antibody uptake by the tumour using an algorithm which converts the data to a probability map based on the significance of the differences in distribution between the early and later images, correctly localised two 0.5cm biopsy positive OC tumours in one of the failures in group II. These results slow that radioimmunoscintigraphy will contribute to staging and evaluating chemotherapy in known OC

  16. Monitoring Levothyroxine Dose during Pregnancy: A Prospective Study

    Juhi Agarwal

    2011-01-01

    Full Text Available Problem statement: Thyroid dysfunction in pregnant women can influence the outcome for mother and fetus at all stages of pregnancy. As the fetus is entirely dependent on maternal thyroid hormones for its development until about 13 weeks of gestation, it is important to ensure adequate thyroxine substitution in pregnant women during the first trimester. Objective: The aim of this prospective study was to explore whether hypothyroidic pregnant women are adequately levothyroxine (L-T4 substituted in early pregnancy. Approach: During March 2008 to July 2009, 93 pregnant females with thyroid diseases were followed at the outpatient department of INMAS. At the first visit 86 patients were on L-T4 substitution for hypothyroidism. Seven other patients had hyperthyroidism. The patients were regularly followed every 4-8 weeks during pregnancy for dose adjustment. Before each visit serum Free Thyroxine (FT4 and TSH concentrations were determined. Results: Of the 86 patients on thyroxine substitution for hypothyroidism 56 (65.12% had serum TSH values within the reference range at their first TSH test. Thirty (34.9% had TSH values outside the reference range. In 5 patients TSH was 4 increase at the first evaluation during pregnancy was 17.46±30.8µg day1. In the 50 patients who needed to increase L-T4, 26% reached a definitive therapeutic dosage within 12th week of pregnancy, 24% within the 20th week and 50% within the 31st week. Conclusion/Recommendations: In 34.9% of pregnant women on L-T4 substitution for hypothyroidism, serum TSH values were abnormal when first tested and they had increased chances of fetal loss if not treated timely. Thyroid function in pregnant women on thyroxine substitution should be monitored as soon as pregnancy has been confirmed and carefully followed during pregnancy.

    2010-05-01

    Full Text Available Abstract Background The frequency of mental illness amongst adolescents and its potential long-term consequences make it an important topic to research in relation to risk and protective factors. Research on the relationship between physical activity and depressive symptoms in adolescents is limited. There is a particular lack of evidence from longitudinal studies. This study examines the relationship between depression and physical activity using the Research with East London Adolescents: Community Health Survey (RELACHS. Methods This was a prospective cohort study. Participants were recruited from three Local Education Authority boroughs in East London in 2001 from year 7 (aged 11-12 and year 9 (aged 13-14 and were followed-up in 2003. All pupils in the 28 schools that took part were eligible for the study. Of the total 3,322 pupils eligible for the survey the overall response rate was 84% (2,789 pupils. A total of 2,093 (75% pupils were also followed-up in 2003. The sample was multiethnic (73% of respondents were non-white and deprived. Just under half of the sample was male (49%. Depressive symptoms were measured using the Short Moods and Feelings Questionnaire (SMFQ. Logistic regression analyses were used to examine the association between physical activity and depressive symptoms both cross-sectionally and longitudinally. Results After adjustments, there was evidence for a cross-sectional association between physical activity and depressive symptoms for both boys and girls at baseline, with a decrease in the odds of depressive symptoms of about 8% for each additional hour of exercise undertaken per week (boys: odds ratio (OR = 0.92, 95% CI 0.85 to 0.99; girls: OR = 0.92, 95% CI 0.85 to 1.00. There was no evidence for an association between a change in physical activity from baseline to follow-up and depressive symptoms at follow-up. Conclusions This study provides some evidence for an association between level of physical activity and

    2014-06-01

    Full Text Available AIM: Prospective observational study of symptomatic pile masses reveals that all masses in a patient may not be of the same size or degree. Since long the only treatment for different degrees of piles had been hemorrhoidectomy. Acceptance for non- surgical modalities have come up in recent past and they are being utilized because they minimize the morbidity and save working hours. Present study has successfully utilized both surgical and non -surgical methods together in a patient in the same sitting. METHODS: 102 patients with symptomatic first to third degree hemorrhoids were studied. Depending upon the degree, treatment modality was selected. Depending on the treatment given patients were divided into four groups. Sclerotherapy alone (n=25, Sclerotherapy & Band ligation (n=17, Sclerotherapy and Hemorrhoidectomy (n=24, sclerotherapy, Band Ligation & Hemorrhoidectomy (n=36. All 102 patients were subjected to four finger Lord’s Dilatation before the definitive procedures. All of them were followed for six months. Symptomatic relief, early side effects and need for re-treatment were evaluated. RESULTS: Satisfactory response was seen in 83 patients (I-20, II-13, III-20, lV-30. Sclerotherapy was more effective for 1st degree than for 2nd degree (p=0.04. Hemorrhoidectomy & band ligation were equally effective for uncomplicated 2nd degree piles. Use of hemorrhoidectomy had a definite edge in 3rd degree cases with or without associated external hemorrhoids and in 2nd degree masses with external pile mass. Local pain (no=32 and bleeding (n=6 were the most common complications. Single session was used in all the groups. None of the patients required additional treatment during follow up. Dietary modifications and life style changes were incorporated in the discharge advice for each patient. CONCLUSIONS: Conservative (non-surgical methods can be effectively used with good results even for 2nd & 3rd degree piles. Sclerotherapy & band ligation have got

    Full Text Available Abstract Background The purpose of this prospective study was to assess the injury rates in male and female adult Canadian Taekwondo athletes relative to total number of injuries, type and body part injured. Methods Subjects (219 males, 99 females participated in the 1997 Canadian National Taekwondo Championships in Toronto, Canada. Injuries were recorded on an injury form to documents any injury seen and treatment provided by the health care team. These data were later used for this study. The injury form describes the athlete and nature, site, severity and mechanism of the injury. Results The overall rate of injuries was 62.9/1,000 athlete-exposures (A-E. The males (79.9/1,000 A-E sustained significantly more injuries than the females (25.3/1,000 A-E. The lower extremities were the most commonly injured body region in the men (32.0 /1,000 A-E, followed by the head and neck (18.3/1,000 A-E. Injuries to the spine (neck, upper back, low back and coccyx were the third most often injured body region in males (13.8/1,000 A-E. All injuries to the women were sustained to the lower extremities. The most common type of injury in women was the contusion (15.2/1,000 A-E. However, men's most common type of injury was the sprain (22.8/1,000 A-E followed by joint dysfunction (13.7/1,000A-E. Concussions were only reported in males (6.9/1,000 A-E. Compared to international counterparts, the Canadian men and women recorded lower total injury rates. However, the males incurred more cerebral concussions than their American colleagues (4.7/1,000 A-E. Conclusions Similar to what was found in previous studies, the current investigation seems to suggest that areas of particular concern for preventive measures involve the head and neck as well as the lower extremities. This is the first paper to identify spinal joint dysfunction.

    Naresh M Punjabi

    2009-08-01

    Full Text Available BACKGROUND: Sleep-disordered breathing is a common condition associated with adverse health outcomes including hypertension and cardiovascular disease. The overall objective of this study was to determine whether sleep-disordered breathing and its sequelae of intermittent hypoxemia and recurrent arousals are associated with mortality in a community sample of adults aged 40 years or older. METHODS AND FINDINGS: We prospectively examined whether sleep-disordered breathing was associated with an increased risk of death from any cause in 6,441 men and women participating in the Sleep Heart Health Study. Sleep-disordered breathing was assessed with the apnea-hypopnea index (AHI based on an in-home polysomnogram. Survival analysis and proportional hazards regression models were used to calculate hazard ratios for mortality after adjusting for age, sex, race, smoking status, body mass index, and prevalent medical conditions. The average follow-up period for the cohort was 8.2 y during which 1,047 participants (587 men and 460 women died. Compared to those without sleep-disordered breathing (AHI: or=30.0 events/h sleep-disordered breathing were 0.93 (95% CI: 0.80-1.08, 1.17 (95% CI: 0.97-1.42, and 1.46 (95% CI: 1.14-1.86, respectively. Stratified analyses by sex and age showed that the increased risk of death associated with severe sleep-disordered breathing was statistically significant in men aged 40-70 y (hazard ratio: 2.09; 95% CI: 1.31-3.33. Measures of sleep-related intermittent hypoxemia, but not sleep fragmentation, were independently associated with all-cause mortality. Coronary artery disease-related mortality associated with sleep-disordered breathing showed a pattern of association similar to all-cause mortality. CONCLUSIONS: Sleep-disordered breathing is associated with all-cause mortality and specifically that due to coronary artery disease, particularly in men aged 40-70 y with severe sleep-disordered breathing.

    2000-10-01

    A prospective study of 7079 people aged 45-74 recruited through general practices in South Wales, Herefordshire and Edinburgh, Scotland was undertaken to test the hypothesis that faecal bile acids are implicated in the causation of large bowel cancer. The population was recruited between 1974 and 1980 and the response rate for stool collection was 67%. Bile acid analyses were performed on those cases that presented by 1990. It was decided in advance to examine the hypothesis separately for left- and right-sided bowel cancer because of known epidemiological differences between the two sites and to exclude the cases presenting within 2 years of the stool sample from the analyses because the cancer could have been present at recruitment and might have possibly affected faecal bile acid concentrations. Each case (n = 51 left-sided and 8 right-sided) was matched with three controls by age (within 5 years), sex, place of residence and time of providing the stool sample (within 3 months). Statistical analyses using conditional logistic regression showed no significant differences between the left-sided cases and controls for any of the concentrations of individual bile acids, total bile acid concentrations, faecal neutral steroids, percentage bacterial conversion and the ratio of lithocholic acid to deoxycholic acid concentrations. There was a statistically significant (P = 0.021) association of the presence of chenodeoxycholic acid (5/8 samples) in the right-sided cases compared with the controls (3/23), odds ratio 6.26 (95% confidence interval 1.19, 32.84). A high proportion of primary bile acids has also been found in other studies of patients with a genetic predisposition to proximal bowel cancer, however this pattern may also occur in low risk groups, such as Indian vegetarians, suggesting that they may predispose to right-sided bowel cancer only in the presence of other, as yet unknown factors. If bile acids are involved in the causation of large bowel cancer, they

    2016-04-01

    Background and purpose - Hip fracture patients usually have low body mass index (BMI), and suffer further postoperative catabolism. How BMI relates to outcome in relatively healthy hip fracture patients is not well investigated. We investigated the association between BMI, survival, and independent living 1 year postoperatively. Patients and methods - This prospective multicenter study involved 843 patients with a hip fracture (mean age 82 (SD 7) years, 73% women), without severe cognitive impairment and living independently before admission. We investigated the relationship between BMI and both 1-year mortality and ability to return to independent living. Results - Patients with BMI > 26 had a lower mortality rate than those with BMI  26 was 2.6 (95% CI: 1.2-5.5) after adjustment for age, sex, and physical status. Patients with BMI > 26 were also more likely to return to independent living after the hip fracture (OR = 2.6, 95% CI: 1.4-5.0). Patients with BMI  26) had a higher survival rate at 1 year, and returned to independent living to a higher degree than those of normal (healthy) weight. The obesity paradox and the recommendations for optimal BMI need further consideration in patients with hip fracture. PMID:26986549

  12. A Prospective Study of Salivary Gland Function in Lymphoma Patients Receiving Head and Neck Irradiation

    Purpose: To determine the radiation dose-response relationship on salivary dysfunction and quality of life (QOL) over time in patients with lymphoma receiving radiation therapy (RT) to the head and neck (H and N). Methods and Materials: We conducted a prospective study on salivary-gland function in lymphoma patients receiving RT to the H and N. Fifteen patients were enrolled on the study. Dose-volume histograms and mean doses to the salivary glands were generated. Radiation-related toxicities and H and N-specific QOL were assessed before treatment and at prespecified time points posttreatment. Factors predicting a decrement in QOL were explored using Fisher's exact test. Results: During RT, 47% of patients experienced Grade ≥ 2 acute toxicity of the salivary gland, mucous membrane, or both. QOL scores improved over time, but up to one third of patients continued to have persistent oral symptoms at 2 years. At 6 months, a mean dose to at least one of the parotids of > 31 Gy was significantly associated with persistent dry mouth (100% vs. 17%, p = 0.02) and sticky saliva (100% vs. 25%, p = 0.04); a mean dose of > 11 Gy to the minor salivary glands was significantly associated with persistent sticky saliva (100% vs. 25%, p = 0.04), although the difference was no longer significant at 1 year. Conclusions: Limiting the mean parotid dose to ≤ 31 Gy and mean minor salivary gland dose to ≤ 11 Gy in lymphoma patients treated to the H and N may help reduce the risk of subacute xerostomia.

  18. A prospective study of tobacco smoking and mortality in Bangladesh.

    Fen Wu

    Full Text Available BACKGROUND: Limited data are available on smoking-related mortality in low-income countries, where both chronic disease burden and prevalence of smoking are increasing. METHODS: Using data on 20,033 individuals in the Health Effects of Arsenic Longitudinal Study (HEALS in Bangladesh, we prospectively evaluated the association between tobacco smoking and all-cause, cancer, and cardiovascular disease mortality during ∼7.6 years of follow-up. Cox proportional hazards models were used to estimate hazard ratios (HRs and their 95% confidence intervals (CIs for deaths from all-cause, cancer, CVD, ischemic heart disease (IHD, and stroke, in relation to status, duration, and intensity of cigarette/bidi and hookah smoking. RESULTS: Among men, cigarette/bidi smoking was positively associated with all-cause (HR 1.40, 95% CI 1.06 1.86 and cancer mortality (HR 2.91, 1.24 6.80, and there was a dose-response relationship between increasing intensity of cigarette/bidi consumption and increasing mortality. An elevated risk of death from ischemic heart disease (HR 1.87, 1.08 3.24 was associated with current cigarette/bidi smoking. Among women, the corresponding HRs were 1.65 (95% CI 1.16 2.36 for all-cause mortality and 2.69 (95% CI 1.20 6.01 for ischemic heart disease mortality. Similar associations were observed for hookah smoking. There was a trend towards reduced risk for the mortality outcomes with older age at onset of cigarette/bidi smoking and increasing years since quitting cigarette/bibi smoking among men. We estimated that cigarette/bidi smoking accounted for about 25.0% of deaths in men and 7.6% in women. CONCLUSIONS: Tobacco smoking was responsible for substantial proportion of premature deaths in the Bangladeshi population, especially among men. Stringent measures of tobacco control and cessation are needed to reduce tobacco-related deaths in Bangladesh.

  19. Anosognosia for hemiplegia: a clinical-anatomical prospective study.

    2010-12-01

    Anosognosia for hemiplegia is a common and striking disorder following stroke. Because it is typically transient and variable, it remains poorly understood and has rarely been investigated at different times in a systematic manner. Our study evaluated a prospective cohort of 58 patients with right-hemisphere stroke and significant motor deficit of the left hemibody, who were examined using a comprehensive neuropsychological battery at 3 days (hyperacute), 1 week (subacute) and 6 months (chronic) after stroke onset. Anosognosia for hemiplegia was frequent in the hyperacute phase (32%), but reduced by almost half 1 week later (18%) and only rarely seen at 6 months (5%). Anosognosia for hemiplegia was correlated with the severity of several other deficits, most notably losses in proprioception, extrapersonal spatial neglect and disorientation. While multiple regression analyses highlighted proprioceptive loss as the most determinant factor for the hyperacute period, and visuospatial neglect and disorientation as more determinant for the subacute phase, patients with both proprioceptive loss and neglect had significantly higher incidence of anosognosia for hemiplegia than those with only one deficit or no deficits (although a few double dissociations were observed). Personal neglect and frontal lobe tests showed no significant relation with anosognosia for hemiplegia, nor did psychological traits such as optimism and mood. Moreover, anosognosia for neglect and prediction of performance in non-motor tasks were unrelated to anosognosia for hemiplegia, suggesting distinct monitoring mechanisms for each of these domains. Finally, by using a voxel-based statistical mapping method to identify lesions associated with a greater severity of anosognosia, we found that damage to the insula (particularly its anterior part) and adjacent subcortical structures was determinant for anosognosia for hemiplegia in the hyperacute period, while additional lesions in the premotor cortex

    2012-11-01

    Full Text Available OBJECTIVES: To determine the frequency of medical adverse events in elderly patients admitted to an acute care geriatric unit, the predictive factors of occurrence, and the correlation between adverse events and hospital mortality rates. METHODS: This prospective study included 171 admissions of patients aged 60 years and older in the acute care geriatric unit in a teaching hospital in Brazil between 2007 and 2008. The following variables were assessed at admission: the patient age, gender, number of prescription drugs, geriatric syndromes (e.g., immobility, postural instability, dementia, depression, delirium, and incontinence, comorbidities, functional status (evaluated with the Katz Index of Independence in Activities of Daily Living, and severity of illness (evaluated with the Simplified Acute Physiology Score Il. The incidence of delirium, infection, mortality, and the prescription of potentially inappropriate medications (based on the Beers criteria were assessed during hospitalization. An observer who was uninvolved in patient care reported the adverse events. RESULTS: The mean age of the sample was 78.12 years. A total of 187 medical adverse events occurred in 94 admissions (55%. The predictors of medical adverse events were undetermined. Compared with the patients with no adverse events, the patients with medical adverse events had a significantly longer hospital stay (21.41 ± 15.08 days versus 10.91 ± 7.21 days and a higher mortality rate (39 deaths [41.5%] versus 17 deaths [22.1%]. Mortality was significantly predicted by the Simplified Acute Physiology Score II score (odds ratio [OR] = 1.13, confidence interval [CI] 95%, 1.07 to 1.20, the Katz score (OR=1.47, CI 95%, 1.18 to 1.83, and medical adverse events (OR = 3.59, CI 95%, 1.55 to 8.30. CONCLUSION: Medical adverse events should be monitored in every elderly hospitalized patient because there is no risk profile for susceptible patients, and the consequences of adverse events are

  1. Acquisition Study On Cawthorne Channel Prospect For SPDC

    The Cawthorne Channel prospect area lies in the Niger River Delta of South Central Nigeria. During 1987 to 1988, 3D seismic was conducted by Western Geophysical Company. According to SPDC's project plan, 4D seismic or 3D re-shoot program will be carried out in the year of 2002, in order to improve seismic data quality, monitor the variations of reservoir, and further to locate the infill wells for improvement of oil output in Cawthorne Channel prospect. From the knowledge of previous 3D, medium to deeper layer reflections show the lower resolution with poor S/N ratio due to lower coverage and limited maximum offset. The purpose of this paper is to introduce one way of optimizing the acquisition parameters such as trace interval, maximum offset, source array pattern and receiver pattern according to the requirement of vertical resolution, horizontal resolution, target depth and maximum frequency components to be protected. Finally the 4D/3D geometries are proposed from the geophysical parameters for Cawthorne Channel prospect

    Disordered eating (DE) and nonsuicidal self-injury (NSSI) commonly co-occur. This study compared several models of the longitudinal relationship between DE and NSSI, including concurrent and prospective models, and examined the possible moderating roles of self-objectification, impulsivity, and emotion dysregulation in these relationships. Individuals with NSSI (N=197) recruited from online forums completed measures of NSSI and DE every 3 months for 1 year. We tested the associations between NSSI and DE using hierarchical linear models. Results supported a concurrent relationship, wherein frequency of NSSI positively covaried with concurrent DE severity. Body surveillance moderated the concurrent relationship between NSSI and DE. Individuals who engaged in more body surveillance endorsed high levels of DE pathology, whereas those lower in body surveillance engaged in more frequent NSSI only at higher levels of DE. In addition, whereas DE did not prospectively predict NSSI, frequency of NSSI predicted more severe DE 3 months later. The prospective relationship between DE and later NSSI was moderated by emotion dysregulation, such that highly dysregulated individuals had a stronger relationship between DE and later NSSI, whereas this relationship was not significant among individuals low in emotion dysregulation. These findings add valuable information regarding the co-occurrence of self-damaging behaviors. PMID:25526840

    Outcomes from patients suffering hip fracture remain poor, with 9% mortality at 30 days and 35% at 1 year. Despite robust guidelines these mortality rates have undergone little change. Admission serum lactate in patients with sepsis or suffering general trauma has been shown to be an indicator of adverse clinical outcomes. We investigated whether venous lactate can predict mortality for hip fracture patients. Over a 12-month period the admission venous lactate of all patients presenting to our institution with hip fractures was prospectively collated. Demographic and patient survivorship data were also prospectively recorded. Multivariate binary logistic regression and Cox proportional hazards ratio analysis was used to evaluate the relationship between admission venous lactate and 30-day mortality and early survivorship, whilst adjusting for age and gender. 770 patients were included in the study. The mean age was 80 years. The overall 30-day mortality for this cohort was 9.5%. Admission venous lactate was associated with early death. A 1mmol/L increase in venous lactate resulted in a 1.9 (95% CI 1.5-2.3 p<0.0001) fold increase in the odds of 30-day mortality and a 1.4 (95% CI: 1.2-1.6 p<0.0001) factor increase in the risk of death at any time after hip fracture. Admission venous lactate remained a predictor of mortality despite adjustment for patients American Society of Anesthesiologists (ASA) grade. Those with an admission serum lactate of 3mmol/L or greater were particularly at risk. This cohort had a 30-day mortality odds that was 5-fold higher than those whose level was less than 3mmol/L (p<0.0001) and at any-time risk of death that was 1.9 times higher (p<0.0001). Those with a level of less than 3mmol/L had a 30-day mortality of 6.8%. For those with an admission venous lactate of 3mmol/L or greater this was four times higher at 28%. The difference was statistically significant (p<0.0001). Elevated admission venous lactate following hip fracture is a

  5. Is Isolated Aphasia Associated with Atrial Fibrillation A Prospective Study

    Carlijn P.A. Giesbers

    2014-07-01

    Full Text Available Background: A cardioembolic source, usually atrial fibrillation (AF, is detected in 14-30% of strokes. If AF is found, anticoagulation therapy provides a substantial decrease of the risk of recurrent cerebrovascular ischemic events. AF is often paroxysmal, and extensive diagnostic procedures may be necessary to detect it in patients. Considering cost-effectiveness and patient burden, however, not every suspected patient can be thoroughly screened. Therefore, the identification of risk factors for AF may be helpful. Previous studies have identified isolated aphasia as a risk factor for AF as the cause of the stroke. These studies, however, were performed with small population samples, in a retrospective setting or focused on a specific subtype of aphasia. The aim of this observational study is to prospectively evaluate whether there is a relation between isolated aphasia and AF as the cause of cerebrovascular ischemia. Methods: All patients admitted to the Atrium Medical Centre, Heerlen, the Netherlands, with cerebrovascular ischemia or transient ischemic attack in the period of August 2009 to March 2010 or October 2013 to January 2014 were included. The patients were evaluated by a neurologist and admitted to the Brain Care Unit for 24-48 h. Medical history, physical examination and diagnostic results were entered in a database. A diagnosis of isolated aphasia was assigned at admission using the National Institutes of Health Stroke Scale (NIHSS. Presence of AF was determined using a 12-lead electrocardiogram (ECG on admission and continuous ECG monitoring for 1-2 days.

    Full Text Available Abstract Background In recent years a number of costs of stroke studies have been conducted based on incidence or prevalence and estimating costs at a given time. As there still is a need for a deeper understanding of factors influencing these costs the aim of this study was to calculate the direct and indirect costs in a younger ( Methods Fifty-eight patients included in a study of home rehabilitation and followed for 1 year after discharge from the rehabilitation unit, were interviewed about their use of health care services, assistance, medications and assistive devices. Costs (defined as the cost for society were calculated. A linear regression of cost and variables of functioning, ability, community integration and health-related quality of life was done. Results Inpatient care contributed substantially to the direct cost with a mean length of stay of 92 days. Rehabilitation during the first year constituted of an average of 28 days in day clinics, 38 physiotherapy sessions and 20 occupational therapy sessions. The total direct mean cost was 80 020 € and the indirect cost 35 129 €. The direct costs were influenced by the process skill (the ability to plan and perform a given task and to adapt when needed and presence of aphasia. Indirect costs for informal care giving increased for patients with a lower health-related quality of life as well as a low score on home integration. Conclusion Costs are high in this group of young (

  9. Diabetes and modifiable risk factors for cardiovascular disease: the prospective Million Women Study

    To compare the effect of potentially modifiable lifestyle factors on the incidence of vascular disease in women with and without diabetes. In 1996-2001 over one million middle-aged women in the UK joined a prospective study, providing medical history, lifestyle and socio-demographic information. All participants were followed for hospital admissions and deaths using electronic record-linkage. Adjusted relative risks (RRs) and incidence rates were calculated to compare the incidence of coronary heart disease and stroke in women with and without diabetes and by lifestyle factors. At recruitment 25,915 women (2.1% of 1,242,338) reported current treatment for diabetes. During a mean follow-up of 6.1 years per woman, 21,928 had a first hospital admission or death from coronary heart disease (RR for women with versus without diabetes = 3.30, 95% CI 3.14-3.47) and 7,087 had a first stroke (RR = 2.47, 95% CI 2.24-2.74). Adjusted incidence rates of these conditions in women with diabetes increased with duration of diabetes, obesity, inactivity and smoking. The 5-year adjusted incidence rates for cardiovascular disease were 4.6 (95% CI 4.4-4.9) per 100 women aged 50-69 in non-smokers with diabetes, 5.9 (95% CI 4.6-7.6) in smokers with diabetes not using insulin and 11.0 (95% CI 8.3-14.7) in smokers with diabetes using insulin. Non-smoking women with diabetes who were not overweight or inactive still had threefold increased rate for coronary disease or stroke compared with women without diabetes. Of the modifiable factors examined in middle aged women with diabetes, smoking causes the greatest increase in cardiovascular disease, especially in those with insulin treated diabetes

  10. Results of a prospective study evaluating the effects of mantle irradiation on pulmonary function

    Thirty patients with Stages I-III Hodgkin's disease receiving mantle irradiation were prospectively evaluated prior to therapy with spirometry, lung volumes, and tests of diffusing capacity (DLCO). Follow-up examinations were performed at 3, 6, and 12 months and then yearly. Sixteen patients had Hodgkin's disease involving the mediastinum at presentation, 10 were smokers, and 16 received either preirradiation or postirradiation chemotherapy. Mantle doses ranged between 2300 cGy and 4000 cGy (mode of 3750 cGy) given at 150 cGy to 170 cGy tumor dose per day with split-course technique. Twenty patients have been tested greater than or equal to 4 years after treatment with a median time from treatment to last pulmonary function test of 8 years. Changes over time in spirometry included an early, mild decrease in both forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1), which returned to baseline by 2 years and then gradually decreased to a 10-15% deficit as compared with predicted values at 6-10 years. Additionally, there was a very slight decrease in FEV1/FVC beginning at 1 year and gradually increasing to an 8% deficit at 6-10 years. Changes over time in lung volumes included a mild nadir of total lung capacity (TLC) and functional residual capacity (FRC) at 6 months to a year, which returned to baseline at 2-4 years and then gradually dropped to a 5-10% deficit at 6-10 years. Mean DLCO for the study group was 20% below predicted values prior to treatment and dropped to a low of 30% below predicted at 6 months following treatment, then gradually returned to baseline by 4 years and showed continued improvement to an overall deficit of approximately 10% at 6-10 years

    2012-07-01

    Little information is available on the characteristics of infants hospitalized for acute bronchiolitis in France. An analysis of hospital records (PMSI) was conducted at the national level to describe the cases of bronchiolitis that require hospitalization among infants under 1 year of age and the factors associated with death. The analysis of all admissions that occurred during 2009, for which the diagnosis of acute bronchiolitis was recorded in the PMSI database for infants aged less than 1 year, was performed. Cases were described according to age, sex, underlying conditions (including bronchopulmonary dysplasia, cystic fibrosis, and congenital heart disease), length of hospital stay, recurrent admissions, admission to an intensive care unit (ICU), and use of assisted ventilation. Factors associated with death during hospitalization were studied by logistic regression. The hospitalization rate was 35.8 per 1000 infants under 1 year in 2009 in France. Approximately 10% of hospitalized infants required ICU admission. Twenty-two infants died. The estimated case-fatality rate was 0.08% among hospitalized infants and 0.56% for those hospitalized in the ICU. Mortality among all infants under 1 year was 2.6/10(5) in France. Factors associated with death were bronchopulmonary dysplasia (OR=6.7, 95% CI [1.5-29.8]), hospitalization in an ICU (OR=6.46, 95% CI [2.4-17.4]), and the use of assisted ventilation (OR=6.2, 95% CI [2.2-17.1]). This study has enabled the quantification of the rate of hospitalization and mortality, and a better description of infants who need hospitalization. The results are consistent with international literature, but further prospective analysis will be needed to better describe the cases at higher risk, aiming to improve their management.

    Prospective, multiyear epidemiologic studies have proven to be highly effective in discovering preventable risk factors for chronic disease. Investigations such as the Framingham Heart Study have produced blueprints for disease prevention and saved millions of lives and billions of dollars. To discover preventable environmental risk factors for disease in children, the US Congress directed the National Institute of Child Health and Human Development, through the Children's Health Act of 2000, to conduct the National Children's Study. The National Children's Study is hypothesis-driven and will seek information on environmental risks and individual susceptibility factors for asthma, birth defects, dyslexia, attention-deficit/hyperactivity disorder, autism, schizophrenia, and obesity, as well as for adverse birth outcomes. It will be conducted in a nationally representative, prospective cohort of 100,000 US-born children. Children will be followed from conception to 21 years of age. Environmental exposures (chemical, physical, biological, and psychosocial) will be assessed repeatedly during pregnancy and throughout childhood in children's homes, schools, and communities. Chemical assays will be performed by the Centers for Disease Control and Prevention, and banks of biological and environmental samples will be established for future analyses. Genetic material will be collected on each mother and child and banked to permit study of gene-environment interactions. Recruitment is scheduled to begin in 2007 at 7 Vanguard Sites and will extend to 105 sites across the United States. The National Children's Study will generate multiple satellite studies that explore methodologic issues, etiologic questions, and potential interventions. It will provide training for the next generation of researchers and practitioners in environmental pediatrics and will link to planned and ongoing prospective birth cohort studies in other nations. Data from the National Children's Study will

    1992-02-01

    One hundred seventy-one nurses had their back strength evaluated on an isokinetic lifting device and filled out an epidemiologic questionnaire. They were then followed prospectively for 2 years to determine the incidence of job-related low-back injuries. The data were analyzed to determine if the injury incidence correlated with any of the strength or epidemiologic variables collected during the original evaluation. Average peak force measured during the isokinetic lift was 63.8 kg + 13.6 kg at a lift speed of 30.5 cm/sec and 59.1 kg + 14.9 kg at a lift speed of 45.7 cm/sec. Sixteen nurses reported an occurrence of job-related low-back pain or injury during the 2-year prospective period. Discriminate statistical techniques showed that none of the strength or epidemiologic variables correlated with the incidence of pain or injury or explained significant amounts of variance when the variables were regressed on strength or work calculated from the lift force/lift height data. It was concluded that in this high risk population, in which loads are heavy and lifting postures are variable, the use of low-back strength or prior history of pain or injury are poor predictors as to subsequent low-back pain or injury.

  19. Optical Simulations and Studies with the PROSPECT-20 Detector

    Stemen, Nathaniel; Prospect Collaboration

    2015-10-01

    The PROSPECT (Precision Reactor Oscillation and SPECTrum) experiment at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory will make a precise measurement of the reactor antineutrino spectrum from a highly-enriched uranium nuclear reactor while also probing for short-baseline oscillations as a signature of possible sterile-neutrinos. Two liquid scintillator detectors at distances of 7-10m and 16-20m from the reactor will identify inverse beta decay events initiated by reactor antineutrinos. The near detector will be divided into optically separated segments filled with lithium loaded liquid scintillator read out by photomultiplier tubes (PMTs) on either end. Light guides will be employed to direct photons from the scintillator cells to the active PMT photo-cathodes. An optical simulation was built to optimize the performance of the detectors with respect to both light collection and detector uniformity and guide the design of the scintillator cells. We present experimental data and simulation results from the PROSPECT-20 prototype detector.

    Background. The impact of early valve surgery (EVS) on the outcome of Staphylococcus aureus (SA) prosthetic valve infective endocarditis (PVIE) is unresolved. The objective of this study was to evaluate the association between EVS, performed within the first 60 days of hospitalization, and outcome of SA PVIE within the International Collaboration on Endocarditis–Prospective Cohort Study. Methods. Participants were enrolled between June 2000 and December 2006. Cox proportional hazards modeling that included surgery as a time-dependent covariate and propensity adjustment for likelihood to receive cardiac surgery was used to evaluate the impact of EVS and 1-year all-cause mortality on patients with definite left-sided S. aureus PVIE and no history of injection drug use. Results. EVS was performed in 74 of the 168 (44.3%) patients. One-year mortality was significantly higher among patients with S. aureus PVIE than in patients with non–S. aureus PVIE (48.2% vs 32.9%; P = .003). Staphylococcus aureus PVIE patients who underwent EVS had a significantly lower 1-year mortality rate (33.8% vs 59.1%; P = .001). In multivariate, propensity-adjusted models, EVS was not associated with 1-year mortality (risk ratio, 0.67 [95% confidence interval, .39–1.15]; P = .15). Conclusions. In this prospective, multinational cohort of patients with S. aureus PVIE, EVS was not associated with reduced 1-year mortality. The decision to pursue EVS should be individualized for each patient, based upon infection-specific characteristics rather than solely upon the microbiology of the infection causing PVIE.

  8. A Prospecting Mineralogy Study:Arsenopyrite In Endogenetic Gold Deposits

    LI Xiaomin; ZHANG Hongzhi

    2001-01-01

    Arsenopyrite is one of very important and common auriferous minerals in endogenetic gold deposits. In seven gold deposits, the prospecting typomorphic characteristics of arsenopyrite, such as morphological typomorphism, composition typomorphism, pyroelectricity typomorphism and so on, were established. The crystal form of arsenopyrite is simple, and the form symbols mainly are {101}, {120}, {210}, {140}, {230}, {012}, etc. The smaller groin and poor crystal form arsenopyrite indicates the better auriferous characteristics. The major elements (Fe, As and S) of gold- bearing arsenopyrite usually show Fe/As + S > 0.5, As/S< 1 which deviates from its theoretical value. The most important trace element is Au and next is Ag in arsenopyrite, and they often show the positive correlation. The pyroelectricity of arsenopyrite can reflect the mineralization epoch, and it also is related to the crystal form and granudarity.

  9. Intracranial hypotension accompanied by trauma. A prospective study in Japan

    To clarify the clinical characteristics of definite and non-definite diagnosis groups in intracranial hypotension accompanied by trauma (IHAT), we undertook investigations of registered patients (n=23) prospectively. The results revealed the following features of IHAT: definite diagnosis group, 4 cases; they had long periods from injury to onset (5.5±5.7 days), but these were markedly shorter than in the non-definite group; 75% of definite cases showed typical postural headache; 75% of definite cases showed dural enhancement on Gd-MRI; all 4 cases had confirmed cerebrospinal fluid (CFS) leakage based on imaging diagnosis with cervical lesions in 2 cases and cervical-thoracic lesions in 2 cases; and 6) good recovery was achieved in them by conservative therapy and blood patch, with a cure rate of 100%. These findings suggest that confirmed CFS leakage is indispensable for reaching definite diagnosis of IHAT. (author)

    Hepatitis B virus (HBV) infection is the most common cause of end stage liver disease in Iran and in Golestan province. Large-scale population-based prospective cohort studies with long term follow-up are the method of choice to accurately understand the natural course of HBV infection. To date, several studies of HBV epidemiology, natural history, progression to cirrhosis and association with HCC have been reported from other countries. However, few of these are prospective and fewer still are population-based. Moreover, the underlying molecular mechanisms and immunogenetic determinants of the outcome of HBV infection especially in low and middle income countries remains largely unknown. Therefore, the hepatitis B cohort study (HBCS), nested as part of the Golestan Cohort Study (GCS), Golestan, Iran was established in 2008 with the objective to prospectively investigate the natural course of chronic hepatitis B with reference to its epidemiology, viral/host genetic interactions, clinical features and outcome in the Middle East where genotype D HBV accounts for >90% of infections. In 2008, a baseline measurement of HBV surface antigen (HBsAg) was performed on stored serum samples of all GCS participants. A sub-cohort of 3,505 individuals were found to be HBsAg positive and were enrolled in the Golestan HBCS. In 2011, all first degree relatives of HBsAg positive subjects including their children and spouses were invited for HBV serology screening and those who were positive for HBsAg were also included in the Golestan HBCS.

    2015-09-01

    Full Text Available Background The incidence rate of acute diarrheal disease in children is a health indicator, and the estimation of these data can help guide public health policies. Objectives The aim of this study was to estimate the incidence and risk factors for acute diarrheal disease in children aged 0 - 1 year. Patients and Methods An observational prospective cohort study was conducted on 210 children recruited at Hospital Nossa Senhora da Conceicao, in Tubarao, state of Santa Catarina, Brazil. Children born between July and September 2012 were followed up for 12 months. The presence of three or more liquid or loose stools during a 24-hour period was considered acute diarrhea. The categories of variables evaluated were comprised of sociodemographic characteristics (per capita income, maternal education, maternal age, access to medical care [public or private], and housing and living conditions [sanitation and hygiene, water supply, daycare attendance, and domestic animal] and characteristics of the child (gender, birth weight, and breastfeeding. Results The incidence of acute diarrhea among the 0 - 1-year-old children was 26.7 cases per 1,000 children per month. Independent risk factors for the occurrence of diarrhea were maternal age under 20 years and health care services provided by the Brazilian National Health System (SUS. Conclusions The high incidence density of diarrhea among the children recruited in this study indicates the need for educational programs directed at people who are involved in this issue.

    2010-01-01

    For this exceptional 25th anniversary of the QCD-Montpellier series of conferences initiated in 85 with the name "Non-perturbative methods", we take the opportunuity to celebrate the 30 + 1 years of the discovery of the SVZ (also called ITEP, QCD or QCD spectral) sum rules by M.A. Shifman, A.I. Vainshtein and V.I. Zakahrov in 79 [1]. In this talk, I have the duty to present the status of the method. I shall (can) not enumerate the vast area of successful applications of sum rules in hadron physics but I shall focus on the historical evolution of field and its new developments. More detailed related discussions and more complete references can be found in the textbooks [2,3].

    Full Text Available Abstract Background Gastroesophageal reflux disease is a common and chronic disorder but long term, prospective studies of the fate of patients seeking medical advice are scarce. This is especially prominent when looking at non-erosive reflux disease (NERD patients. Methods We designed a prospective cohort to assess the long term outcome of GERD patients referring to gastroenterologists. Consecutive consenting patients, 15 years of age and older, presenting with symptoms suggestive of GERD referring to our outpatient clinics undergo a 30 minute interview. Upper gastrointestinal endoscopy is performed for them with protocol biopsies and blood samples are drawn. Patients are then treated according to a set protocol and followed regularly either in person or by telephone for at least 10 years. Discussion Our data show that such a study is feasible and follow-ups, which are the main concern, can be done in a fairly reliable way to collect data. The results of this study will help to clarify the course of various subgroups of GERD patients after coming to medical attention and their response to treatment considering different variables. In addition, the basic symptoms and biological database will fuel further molecular epidemiologic studies.

  15. Radiotherapy in stage IIA and IIB testicular seminoma with reduced portals: a prospective multicenter study

    Purpose: A prospective multicenter study was carried out to estimate the treatment outcome of radiotherapy in Stage II seminoma after the application of modern staging and radiotherapy techniques. The lower margin of the iliac field was positioned on the upper rim of the acetabulum to reduce the amount of scattered irradiation to the remaining testicle. Methods and Materials: The study was carried out in 25 centers in Germany. Patients with pure seminoma, negative AFP-values, and retroperitoneal lymph node metastases of less than 5 cm in diameter were entered into the study. All patients received a ventrodorsal opposed field irradiation of the para-aortic and the ipsilateral iliac lymph nodes. The fields extended from the top of the 11th thoracic vertebra to the top of the acetabulum. Patients in Stage IIA (lymph nodes <2 cm) received 30 Gy, and patients with Stage IIB (lymph nodes between 2 and 5 cm) 36 Gy total dose. Results: 39 patients in Stage IIA and 19 patients in Stage IIB were evaluated. After a median observation time of 37 months all patients are alive and disease free. Recurrence free survival in stage IIA was 100%. Two patients in Stage IIB experienced a recurrence 10 and 17 months after the end of radiotherapy. The actuarial recurrence free survival estimate in Stage IIB was 94.1% for 1 year and 87.4% for 2 years. One recurrence in Stage IIB occurred in the mediastinum, one in the mediastinum, and one the lung. Both patients could be salvaged by chemotherapy. There were no pelvic recurrences. The treatment was well tolerated, with nausea being the most common side effect (56.9% Grade 1, 15.5% Grade 2, and 8.6% Grade 3). Diarrhea occurred in 15.5% (Grade 1), 15.5% (Grade 2), and 5.2% (Grade 3) of the patients. Conclusions: The outcome of para-aortic and ipsilateral iliac irration in Stage IIA/B testicular seminoma is excellent with the currently available staging methods and treatment facilities. The treatment is well tolerated. The lower margin of the

  16. AN OVERVIEW OF SINONASAL POLYPOSIS: A PROSPECTIVE STUDY

    Kabikanta

    2016-03-01

    Full Text Available INTRODUCTION Sinonasal polyposis, one of the most common inflammatory mass lesions of the nose affecting up to 40% of the population. They present with nasal obstruction, anosmia, rhinorrhoea, post-nasal drip, and less commonly headache. Their aetiology remains unclear, but they are known to have associations with allergy, asthma, infection, fungus, cystic fibrosis, and aspirin sensitivity. Strong genetic factors are implicated in the pathogenesis of SNP, but genetic and molecular alterations required for its development and progression are still unclear. Management of SNP involves a combination of conservative treatment and surgical treatment. There is good evidence for the use of corticosteroids (systematic and topical, both as primary treatment and as postoperative prophylaxis against recurrence, but the prolonged course of the disease and adverse effect of systematic steroid limits their use. Surgical treatment has been refined significantly over the past 20 years with the advent of endoscopic sinus surgery and, in general, is reserved for cases refractory to medical treatment. Recurrence of the polyposis is common with severe disease recurring in up to 10% of patients. Over the last two decades, increasing insights in the pathophysiology of nasal polyposis opens prospective for new pharmacological treatment options, with eosinophilic inflammation, IgE, fungi and staphylococcus aureus as potential targets. A better understanding of the pathophysiology underlying the persistent inflammatory state in SNP is necessary to ultimately develop novel pharmacotherapeutic approaches. Here, we present the newer treatment options available for better control and possibly cure of the disease.

  20. Impact of Chemotherapy on Diet and Nutritional Status of Women with Breast Cancer: A Prospective Study.

    Isis Danyelle Dias Custódio

    Full Text Available Certain food groups are often rejected during chemotherapy (CT due to the side effects of treatment, which may interfere with adequate diet and nutritional status. The aim of this study was to evaluate the treatment impact on the diet and nutritional status of women with breast cancer (BC. In this prospective longitudinal study, conducted in 2014-2015, 55 women diagnosed with BC, with a mean age 51.5±10.1 years, were followed and data were collected at three different times. Anthropometric and dietary assessments were performed, the latter by applying nine 24h dietary recalls, by using the Brazilian Healthy Eating Index Revised (BHEI-R, and calculating the prevalence of inadequacy by the EAR cut-off point method. Regarding the BHEI-R analysis, the majority of women had a "diet requires modification', both at the beginning (T0, 58.2%, n = 32 and during treatment (T1, 54.5%, n = 30. However, after the end of the CT, the greater percentage of patients (T2, 49.1%, n = 27 were classified as having an "inadequate diet", since the Total Fruit consumption as well as the Dark Green and Orange Vegetable and Legume consumption decreased significantly during treatment (p = 0.043 and p = 0.026, respectively. There was a significant reduction in the intake of macro and micronutrients, with a high prevalence of inadequacy, of up to 100%, for calcium, iron, phosphorus, magnesium, niacin, riboflavin, thiamin, vitamin B6, vitamin C and zinc. Assessment of the nutritional status indicated that 56% (n = 31 of patients were overweight at these three different times. Weight, BMI and Waist Circumference increased significantly, indicating a worse nutritional status, and there was a correlation between poor diet quality and higher values for BMI, Waist-Hip Ratio and Waist-to-Height Ratio.

    The majority of U.S. parents spank their children, often beginning when their children are very young. We examined families (N=2,788) who participated in a longitudinal community-based study of new births in urban areas. Prospective analyses examined whether spanking by the child's mother, father, or mother's current partner when the child was 1-year-old was associated with household CPS involvement between age 1 and age 5. Results indicated that 30% of 1-year-olds were spanked at least once in the past month. Spanking at age 1 was associated with increased odds of subsequent CPS involvement (adjusted odds ratio=1.36, 95% CI [1.08, 1.71], pchildren, there was a 33% greater probability of subsequent CPS involvement for children who were spanked at age 1. Given the undesirable consequences of spanking children and a lack of empirical evidence to suggest positive effects of physical punishment, professionals who work with families should counsel parents not to spank infants and toddlers. For optimal benefits, efforts to educate parents regarding alternative forms of discipline should begin during the child's first year of life. PMID:24602690

  4. Residual deficits in quality of life one year after intensity-modulated radiotherapy for patients with locally advanced head and neck cancer. Results of a prospective study

    Patients with locally advanced head and neck cancer (LAHNC) undergo life-changing treatments that can seriously affect quality of life (QoL). This prospective study examined the key QoL domains during the first year after intensity-modulated radiotherapy (IMRT) and identified predictors of these changes in order to improve patient outcomes. A consecutive series of patients with LAHNC completed the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core module (QLQ-C30) and the HNC-specific QLQ-HN35 before (t0) and at the end (t1) of definitive or adjuvant IMRT, then at 6-8 weeks (t2), 6 months (t3), and 1 year (t4) after IMRT. Patients (n = 111) completing questionnaires at all five time points were included (baseline response rate: 99 %; dropout rate between t0 and t4: 5 %). QoL deteriorated in all domains during IMRT and improved slowly during the first year thereafter. Many domains recovered to baseline values after 1 year but problems with smelling and tasting, dry mouth, and sticky saliva remained issues at this time. Increases in problems with sticky saliva were greater after 1 year in patients with definitive versus adjuvant IMRT (F = 3.5, P = 0.05). QoL in patients with LAHNC receiving IMRT takes approximately 1 year to return to baseline; some domains remain compromised after 1 year. Although IMRT aims to maintain function and QoL, patients experience long-term dry mouth and sticky saliva, particularly following definitive IMRT. Patients should be counseled at the start of therapy to reduce disappointment with the pace of recovery. (orig.)

    2014-08-01

    This is the first prospective study in a contemporary Australian/New Zealand population to determine the prevalence of testosterone deficiency in testicular cancer survivors at 12 months from treatment, and any association with poorer quality of life. Hormone assays from 54 evaluable patients in a prospective cohort study revealed biochemical hypogonadism in 18 patients (33%) and low-normal testosterone in 13 patients (24%). We found no association between testosterone levels and quality of life (all P > 0.05). Hypogonadal patients should be considered for testosterone replacement to prevent long-term morbidity.

    Purpose: To prospectively compare plans generated with iCycle, an in-house-developed algorithm for fully automated multicriterial intensity modulated radiation therapy (IMRT) beam profile and beam orientation optimization, with plans manually generated by dosimetrists using the clinical treatment planning system. Methods and Materials: For 20 randomly selected head-and-neck cancer patients with various tumor locations (of whom 13 received sequential boost treatments), we offered the treating physician the choice between an automatically generated iCycle plan and a manually optimized plan using standard clinical procedures. Although iCycle used a fixed “wish list” with hard constraints and prioritized objectives, the dosimetrists manually selected the beam configuration and fine tuned the constraints and objectives for each IMRT plan. Dosimetrists were not informed in advance whether a competing iCycle plan was made. The 2 plans were simultaneously presented to the physician, who then selected the plan to be used for treatment. For the patient group, differences in planning target volume coverage and sparing of critical tissues were quantified. Results: In 32 of 33 plan comparisons, the physician selected the iCycle plan for treatment. This highly consistent preference for the automatically generated plans was mainly caused by the improved sparing for the large majority of critical structures. With iCycle, the normal tissue complication probabilities for the parotid and submandibular glands were reduced by 2.4% ± 4.9% (maximum, 18.5%, P=.001) and 6.5% ± 8.3% (maximum, 27%, P=.005), respectively. The reduction in the mean oral cavity dose was 2.8 ± 2.8 Gy (maximum, 8.1 Gy, P=.005). For the swallowing muscles, the esophagus and larynx, the mean dose reduction was 3.3 ± 1.1 Gy (maximum, 9.2 Gy, P<.001). For 15 of the 20 patients, target coverage was also improved. Conclusions: In 97% of cases, automatically generated plans were selected for treatment because of

    Myhre, Kjersti; Lau, Bjørn; Marchand, Gunn Hege; Leivseth, Gunnar; Bautz-Holter, Erik; Røe, Cecilie

    2016-06-01

    Purpose The main aim of this study was to assess changes in perceived demand, control and support at work of neck and back pain patients over 1 year. We also hypothesised that perceived changes in demand, control and support at work were associated with clinical improvement, reduced fear-avoidance beliefs and successful return to work. Methods Four hundred and five sick-listed patients referred to secondary care with neck or back pain were originally included in an interventional study. Of these, two hundred and twenty-six patients reported perceived psychosocial work factors at both baseline and 1-year follow-up, and they were later included in this prospective study. Changes in demand, control and support dimensions were measured by a total of nine variables. Results At the group level, no significant differences were found among the measured subscales. At the individual level, the regression analyses showed that decreases in fear-avoidance beliefs about work were consistently related to decreases in demand and increases in control, whereas decreases in disability, anxiety and depression were related to increases in support subscales. Conclusions The perception of demand, control and support appear to be stable over 1 year in patients with neck and back pain, despite marked improvement in pain and disability. Disability, anxiety, depression and fear-avoidance beliefs about work were significantly associated with the perception of the work environment, whereas neck and back pain were not. PMID:26286432

  4. Weight loss on stimulant medication: how does it affect body composition and bone metabolism? – A prospective longitudinal study

    2012-12-01

    Full Text Available Abstract Objective Children treated with stimulant medication for attention deficit hyperactivity disorder (ADHD often lose weight. It is important to understand the implications of this during growth. This prospective study was designed to quantify the changes in body composition and markers of bone metabolism on starting treatment. Methods 34 children (29 boys aged 4.7 to 9.1 years newly diagnosed with ADHD were treated with dexamphetamine or methylphenidate, titrating the dose to optimise the therapeutic response. Medication was continued for as long as clinically indicated. Body composition and bone density (dual-energy X-ray absorptiometry were measured at baseline, 6 months and 3 years; changes were analysed in Z-scores based on data from 241 healthy, local children. Markers of bone turnover were measured at baseline, 3 months and 3 years. Results Fat loss of 1.4±0.96kg (total fat 5.7±3.6 to 4.3±3.1kg, p Conclusions Stimulant medication was associated with early fat loss and reduced bone turnover. Lean tissue including bone increased more slowly over 3 years of continuous treatment than would be expected for growth in height. There was long-term improvement in the proportion of central fat for height. This study shows that relatively minor reductions in weight on stimulant medication can be associated with long-term changes in body composition. Further study is required to determine the effects of these changes on adult health.

  5. A Review of Studies of Danger Perception and Prospects of its Study in Clinical Psychology Development

    Veschikova M.I.,

    2015-02-01

    Full Text Available The objective of studies of danger perception is to predict the behavior of a person, group, or society in terms of the potential hazard, to identify the main groups of factors that affect the risk assessment and sources of distortion of the evaluation. The review presents the sociological theories of danger, reveals the gender differences in the danger perception, and describes in details the individual factors of danger perception. We discuss the prospects of studying the outside world danger perception in clinical psychology of development. We emphasize that the key period for the development of danger assessment process is adolescence, because this is the age when most significant quantitative and qualitative changes in the cognitive sphere occur: the development of abstract logical thinking, increased interest to the life and death, the appearance of “personal myth”.

    Hall, Martica H.; Casement, Melynda D.; Troxel, Wendy M.; Matthews, Karen A.; Bromberger, Joyce T.; Kravitz, Howard M.; Krafty, Robert T.; Buysse, Daniel J.

    2015-01-01

    Study Objectives: Evaluate whether levels of upsetting life events measured over a 9-y period prospectively predict subjective and objective sleep outcomes in midlife women. Design: Prospective cohort study. Setting: Four sites across the United States. Participants: 330 women (46–57 y of age) enrolled in the Study of Women's Health Across the Nation (SWAN) Sleep Study. Interventions: N/A. Measurements and Results: Upsetting life events were assessed annually for up to 9 y. Trajectory analysis applied to life events data quantitatively identified three distinct chronic stress groups: low stress, moderate stress, and high stress. Sleep was assessed by self-report and in-home polysomnography (PSG) during the ninth year of the study. Multivariate analyses tested the prospective association between chronic stress group and sleep, adjusting for race, baseline sleep complaints, marital status, body mass index, symptoms of depression, and acute life events at the time of the Sleep Study. Women characterized by high chronic stress had lower subjective sleep quality, were more likely to report insomnia, and exhibited increased PSG-assessed wake after sleep onset (WASO) relative to women with low to moderate chronic stress profiles. The effect of chronic stress group on WASO persisted in the subsample of participants without baseline sleep complaints. Conclusions: Chronic stress is prospectively associated with sleep disturbance in midlife women, even after adjusting for acute stressors at the time of the sleep study and other factors known to disrupt sleep. These results are consistent with current models of stress that emphasize the cumulative effect of stressors on health over time.

  10. Fracture Risk Assessment in Chronic Kidney Disease, Prospective Testing Under Real World Environments (FRACTURE: a prospective study

    West Sarah L

    2010-08-01

    Full Text Available Abstract Background Chronic kidney disease (CKD is associated with an increased risk of fracture. Decreased bone mass and disruption of microarchitecture occur early in the course of CKD and worsens with the progressive decline in renal function so that at the time of initiation of dialysis at least 50% of patients have had a fracture. Despite the excess fracture risk, and the associated increases in morbidity and mortality, little is known about the factors that are associated with an increase in fracture risk. Our study aims to identify prognostic factors for bone loss and fractures in patients with stages 3 to 5 CKD. Methods This prospective study aims to enroll two hundred and sixty men and women with stages 3 to 5 CKD. Subjects will be followed for 24 months and we will examine the ability of: 1 bone mineral density by dual x-ray absorptiometry at the spine, hip, and radius; 2 volumetric bone density by high resolution peripheral quantitated computed tomography at the radius and tibia; 3 serum markers of bone turnover; 4 bone formation rate by bone biopsy; and 5 muscle strength and balance to predict spine and non-spine fractures, identified by self-report and/or vertebral morphometry. All measurements will be obtained at baseline, at 12 and at 24 months with the exception of bone biopsy, which will be measured once at 12 months. Subjects will be contacted every 4 months to determine if there have been incident fractures or falls. Discussion This study is one of the first that aims to identify risk factors for fracture in early stage CKD patients. Ultimately, by identifying risk factors for fracture and targeting treatments in this group-before the initiation of renal replacement therapy - we will reduce the burden of disease due to fractures among patients with CKD.

    Forward, D P; Singh, H P; Dawson, S; Davis, T R C

    2009-02-01

    The aim of this study was to assess the effect of malunion of scaphoid fractures on the clinical outcome at 1 year. Forty-two consecutive patients with united scaphoid waist fractures which had been treated non-operatively underwent longitudinal CT scans to confirm union and assess malunion at 12 to 18 weeks after injury. A blind clinical assessment was made and the Patient Evaluation Measure (PEM) and DASH questionnaires were completed by all the patients 1 year after injury. The group consisted of 38 men and four women with a mean age of 31 years at the time of injury. Correlation analysis revealed no significant relationships between any of the outcome measures (range of motion, grip strength and PEM and DASH scores) and any of the three measures of malunion (height-to-length ratio, the dorsal cortical angle and the lateral intra-scaphoid angle).

    2015-01-01

    Full Text Available The epidemiology of ankle fractures in old people is changing as time passes on. The incidence of ankle fractures increases with advancing age. The study conducted was among a rural popula-tion which comprised of 68 women (32 women with ankle fractures & 36 women with foot fractures. Patients studied were in the age group more than 50 years. The study highlights the etiological & risk factors for fractures of ankle & foot. The commonest ankle fracture was the lateral malleolar fracture & the commonest foot fracture was the 5th Metatarsal fracture. Diabetes is a risk factor which increases the occurrence of ankle and foot injuries.

  5. Effects of aversive stimuli on prospective memory. An event-related fMRI study.

    Massimiliano Rea

    Full Text Available Prospective memory (PM describes the ability to execute a previously planned action at the appropriate point in time. Although behavioral studies clearly showed that prospective memory performance is affected by the emotional significance attributed to the intended action, no study so far investigated the brain mechanisms subserving the modulatory effect of emotional salience on PM performance. The general aim of the present study was to explore brain regions involved in prospective memory processes when PM cues are associated with emotional stimuli. In particular, based on the hypothesised critical role of the prefrontal cortex in prospective memory in the presence of emotionally salient stimuli, we expected a stronger involvement of aPFC when the retrieval and execution of the intended action is cued by an aversive stimulus. To this aim BOLD responses of PM trials cued by aversive facial expressions were compared to PM trials cued by neutral facial expressions. Whole brain analysis showed that PM task cued by aversive stimuli is differentially associated with activity in the right lateral prefrontal area (BA 10 and in the left caudate nucleus. Moreover a temporal shift between the response of the caudate nucleus that preceded that of aPFC was observed. These findings suggest that the caudate nucleus might provide an early analysis of the affective properties of the stimuli, whereas the anterior lateral prefrontal cortex (BA10 would be involved in a slower and more deliberative analysis to guide goal-directed behaviour.

  6. Prospective Elementary School Teachers’ Views about Socioscientific Issues: A Concurrent Parallel Design Study

    Muhammet ÖZDEN

    2015-06-01

    Full Text Available The purpose of this research is to examine the prospective elementary school teachers’ perceptions on socioscientific issues. The research was conducted on prospective elementary school teachers studying at a university located in western Turkey. The researcher first taught the subjects of global warming and nuclear power plants from a perspective of socioscientific issues in the science and technology education course and then conducted the research. Concurrent parallel design, one of the mixed-method research approaches, was used to conduct the research. In this context, semi-structured interviews were conducted with eight teachers in the qualitative strand of the study to explore the phenomenon. The data obtained from the interviews were analyzed using thematic analysis. During the quantitative strand of the research, 113 prospective teachers were administered a questionnaire form. The results of the study revealed that none of the participating prospective teachers mentioned about the religious and cultural characteristics of socioscientific issues, and they need training about how to use socioscientific issues in teaching.

  7. An ecological approach to prospective and retrospective timing of long durations: a study involving gamers.

    Simon Tobin

    Full Text Available To date, most studies comparing prospective and retrospective timing have failed to use long durations and tasks with a certain degree of ecological validity. The present study assessed the effect of the timing paradigm on playing video games in a "naturalistic environment" (gaming centers. In addition, as it involved gamers, it provided an opportunity to examine the effect of gaming profile on time estimation. A total of 116 participants were asked to estimate prospectively or retrospectively a video game session lasting 12, 35 or 58 minutes. The results indicate that time is perceived as longer in the prospective paradigm than in the retrospective one, although the variability of estimates is the same. Moreover, the 12-minute session was perceived as longer, proportionally, than the 35- and 58-minute sessions. The study also revealed that the number of hours participants spent playing video games per week was a significant predictor of time estimates. To account for the main findings, the differences between prospective and retrospective timing are discussed in quantitative terms using a proposed theoretical framework, which states that both paradigms use the same cognitive processes, but in different proportions. Finally, the hypothesis that gamers play more because they underestimate time is also discussed.

    2014-01-01

    This paper introduces the characteristics of Computed Tomography (CT) technology and reviews its history, current situation, representative achievements, and use of using CT technology on frozen soil study, including auxiliary equipment specially de-signed for frozen soil studies. CT numbers are used to analyze frozen soil internal structure change, defining and exploring dam-age evolution, and use of CT images on observing soil mesostructure. Finally, this paper presents existing problems confronted by using CT in frozen soil studies, possible solutions and challenges, among which, we introduce high quality CT image processing for frozen soils, and relations between CT number change and each component change on frozen soil samples within the region of interest. It is shown that present CT technology is one of the most ideal and effective technology to study frozen soil mesostructure using non-destructive testing. CT technology will play a key role in the study and development in the field of frozen soil by means of auxiliary equipment and the digital imaging processing.

    To introduce a new designed suture technique in annular repair under the microendoscopic discectomy (MED) surgery and to evaluate the clinical application of the technique in annular repair under MED with at least 2-year follow-up period.A new method of annular repair was designed and named "jetting suture" technique. Thirty consecutive patients with lumbar disc herniation were enrolled in the prospective single-cohort observational study. Patients were followed up at intervals of preoperative, postoperative 1 week, 3 months, 6 months, 1 year, and last follow-up. The clinical outcomes were evaluated by using Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index, and modified Mcnab criteria.The procedure was successfully performed in all cases. No case required conversion to an open procedure. The mean age of patients was 36.6 years. Average blood loss was 45.8 ± 10.2 mL. The preoperative symptoms were alleviated significantly after surgery. All the standardized measures improved significantly at the last follow-up, including JOA score (10.1 to 26.6; P disc herniation was reported.The designed "jetting suture" technique in annular repair under MED can be performed safely and effectively. It could be a viable alternative to annular repair under lumbar discectomy. PMID:27495101

    Full Text Available Peritonitis is defined as inflammation of peritoneum that lines the abdominal cavity and the organs contained therein. In Surgical practice we most often encounter cases of peritonitis which are mostly secondary to hollow viscous perforation. Purpose of our study is to find out which type of peritonitis is more common in our institute, which is the most common bacteria isolated from peritoneal fluid and which antibiotic is it most sensitive to. We studied 104 cases o f age group 16 and above of both sex who presented with clinical features of peritonitis. Peritoneal fluid was obtained and sent for culture and sensitivity. Peritoneal fluid culture was positive in 55.76% cases. The incidence of culture positivity increas ed with duration of presentation. Gastro duodenal perforation was the most common etiological factor for peritonitis found in 42.86% cases followed by ileal perforation. E. c oli was the most common bacteria isolated in study group followed by klebsiella. M ost of the cultures were monomicrbial. E. coli was sensitive to amikacin, imipenem and meropenem (100%. So in our study Gram negative infection is more common in surgical peritonitis. Identification of bacteria and its sensitivity to the antibiotics is he lpful to avoid injudicious use of antibiotics in surgical peritonitis. Proper choice of antibiotics along with surgical management and proper resuscitation in cases of surgical peritonitis can reduces mortality and morbidity associated with these high risk cases

    2015-09-01

    Full Text Available Visualization of the pancreas was far better by CT than b y ultrasound. Ultrasound had certain limitation. Due to bowel gas the pancreas may not be visualized. Extra pancreatic spread of inflammation and vascular complications was not always picked up by Ultrasonography. These limitations were overcome with the u se of CT which yielded more diagnostic information in the evaluation of acute pancreatitis. CT is a confirmative investigation in diagnosis and staging of acute pancreatitis. MCTSI is a very useful tool for the screening of patients with acute pancreatitis for the classification of severity accurately and to predict the clinical outcome. OBJECTIVES OF STUDY: To determine the value of computed tomography in evaluation of early diagnosis of acute pancreatitis. To evaluate the complications using computed tom ography severity index. MATERIAL AND METHODS: The study was conducted on 100 patients with clinical suspicion of acute pancreatitis, altered biochemical parameters (Serum amylase, Serum lipase in favor of acute pancreatitis, ultrasonography suggestive of acute pancreatitis and complications known case of chronic pancreatitis with features of acute symptoms who were referred to the department of Radiodiagnosis, Basaveshwar teaching & General Hospital, Kalaburagi.

    2015-12-01

    Little research has been done on comparing confessions regarding mental health. In the present study, 320 people (78 Buddhists, 77 Catholics, 89 Protestants and 79 Muslims) were compared in terms of their symptom severity. Buddhists and Protestants had lower scores than Catholics and Muslims for obsessive-compulsive behavior and hostility. Muslim group had the highest comparative scores for psychoticism. Buddhists and Protestants had comparatively low scores for paranoid ideation and overall symptom severity, with Catholics and Muslims having high ones. Results reveal that confession should be taken in account in psychological research and diagnosis, since it is explicitly associated with psychological well-being. PMID:25204789

    Full Text Available As the number of major surgical procedures has increased in recent years, so there has been an increase in incisional hernias. With gained experience and new materials, laparoscopic repair of incisional hernia is now applied. This study was aimed to compare the results of incisional hernia repair with the open surgery or laparoscopic approach at the only centre in the region for laparoscopic incisional hernia repair. A total of 55 cases of incisional hernia at the General Surgery Clinic of SDU between November 2012 and 2014 were underwent laparoscopic ventral hernia repair (L-VHR and conventional incisional hernia repair (C-VHR. From the L-VHR group 6 cases and from the C-VHR 9 cases were excluded from the study, as they did not meet the inclusion criteria or did not wish to participate in the study. The two techniques were compared in respect of operative time, length of hospital stay, postoperative pain scores, complications and recurrence. A total of 40 cases of incisional hernia repair were evaluated. The mean follow-up period was found as 12.75±4.19 months. No difference was determined between the characteristics of the patients due to age, body mass index, American Society of Anesthesiologists (ASA score, comorbidities, hernia size, and follow-up. In the laparoscopic repair group, the postoperative pain scores, complication rates and duration of hospital stay were found significantly superior to those of the open technique group. While there was no mortality seen and wound complications as a morbidity were 0 % in the L-VHR (n = 0 and 20 % in C-VHR group (n = 4. In the comparison of mean operative time, the duration of surgery was significantly shorter in the laparoscopic repair group (67.25±19.23 min compared to the open technique group (91.50±24.87 min (p=0.001. Laparoscopic repair was associated with less postoperative pain (4.35±1.03 vs 5.60±1.31, p=0.002, lesser postoperative complications (5% vs. 35%, p=0.044, and shorter

  10. Prospective studies of HTR fuel cycles involving plutonium

    High Temperature Gas Cooled reactors (HTRs) are able to accommodate a wide variety of mixtures of fissile and fertile materials without any significant modification of the core design. This flexibility is due to an uncoupling between the parameters of cooling geometry, and the parameters which characterize neutronic optimisation (moderation ratio or heavy nuclide concentration and distribution). Among other advantageous features, an HTR core has a better neutron economy than a LWR because there is much less parasitic capture in the moderator (capture cross section of graphite is 100 times less than the one of water) and in internal structures. Moreover, thanks to the high resistance of the coated particles, HTR fuels are able to reach very high burn-ups, far beyond the possibilities offered by other fuels (except the special case of molten salt reactors). These features make HTRs especially interesting for closing the nuclear fuel cycle and stabilizing the plutonium inventory. A large number of fuel cycle studies are already available today, on 3 main categories of fuel cycles involving HTRs : i) High enriched uranium cycle, based on thorium utilization as a fertile material and HEU as a fissile material; ii) Low enriched uranium cycle, where only LEU is used (from 5% to 12%); iii) Plutonium cycle based on the utilization of plutonium only as a fissile material, with (or without) fertile materials. Plutonium consumption at high burnups in HTRs has already been tested with encouraging results under the DRAGON project and at Peach Bottom. To maximize plutonium consumption, recent core studies have also been performed on plutonium HTR cores, with special emphasis on weapon-grade plutonium consumption. In the following, we complete the picture by a core study for a HTR burning reactor-grade plutonium. Limits in burnup due to core neutronics are investigated for this type of fuel. With these limits in mind, we study in some detail the Pu cycle in the special case of a

    De Venter, Maud; Smets, Jorien; Raes, Filip; Wouters, Kristien; Franck, Erik; Hanssens, Myriam; Jacquemyn, Yves; Sabbe, Bernard G C; Van Den Eede, Filip

    2016-04-01

    Studies on the impact of childhood trauma on postpartum depression show inconsistencies and methodological limitations. The present study examines the effect of childhood trauma on depression 12 and 24 weeks after childbirth, while controlling for history of depression, depression symptoms during pregnancy and type D personality. During the third trimester of pregnancy, 210 women completed self-report questionnaires assessing depression (current and/or past episodes), childhood trauma and type D personality, of whom 187 participated in the postpartum follow-up, with depression symptoms being reassessed at 12 and 24 weeks after delivery with three depression outcome measures. Eventually, 183 participants were retained for analysis. Results indicated no predictive value of childhood trauma on postpartum depression in the univariate analyses, nor after controlling for previous depression, depression symptoms during pregnancy and type D personality. However, past depression and depression symptoms during pregnancy did independently and convincingly predict postpartum depression, especially at 12 weeks and to a lesser extent at 24 weeks following childbirth. Overall, we found no significant association between childhood trauma and postpartum depression. Past depression and depression symptoms during pregnancy are more relevant factors to assess before childbirth. PMID:26189446

    Bergendal, T; Engquist, B

    1998-01-01

    The aim of this study was to evaluate the clinical function and long-term prognosis of overdentures retained by a small number of implants in the maxilla and mandible using one of two different attachment systems. Included in the study were all patients referred to specialty clinics in Jönköping and Linköping, Sweden, during the treatment period who needed an overdenture and could be provided with a minimum number of two bilaterally-placed implants. Excluded were patients with bone-grafted jaws, irradiated cancer patients, heavy bruxers, and patients who had lost a fixed prosthesis because of implant losses. The patients were randomly assigned to receive one retentive system, either a round 2-mm-diameter bar with clips or ball attachments (Nobel Biocare). Eighteen overdentures were placed in maxillae and 32 in mandibles, supported by a total of 115 Brånemark implants. Of the implants placed, 86.1% were continuously osseointegrated. The cumulative implant survival rates after 7 years of loading were 75.4% in the maxillae and 100% in the mandibles. There was no difference in implant survival rate between the attachment systems. Patients with implant losses were characterized by severely resorbed maxillary ridges and inferior bone quality, together with unfavorable loading circumstances such as short implants combined with long leverages. Complications and prosthetic adjustments were mostly resolved early and easily. PMID:9581412

Random sampling of 1000 married women resident in Sanandaj city was conducted and underwent a standard interview as well as completed a 23-part questionnaire. 15 % and 38 % of the women had been assaulted by their husbands during the past year or in their marriage, respectively between 1 and 11 or more occasions. Economic problems were the most frequent cause of domestic quarrel, while there was a significant association between the husband’s educational level and the violence against their wives (P=0.001.The physical violence against housewives was significantly more frequent than the employed ones .The husbands job was also significantly associated with their violence The existence of child or daughter in the family had a preventive role in domestic physical violence against women. Logit Regression Model for prediction of physical violence against women (Y during the marriage was: "Y=0.014- 0.029 woman’s age +0.199 numbers of children -0.238 man’s education +0.589 woman’s job ". This study confirms for Sanandaj city of Iran, the high frequency of physical violence against women by their husbands. Cultural education and supportive measures are essential to control that. Screening protocol for the detection of domestic violence in family planning Health Care System is recommended.

    Full Text Available The etiology of kwashiorkor remains enigmatic and longitudinal studies examining potential causes of kwashiorkor are scarce. Using historical, longitudinal study data from the rural area of Bwamanda, Democratic Republic of Congo, we investigated the potential causal association between diet and the development of kwashiorkor in 5 657 preschool children followed 3-monthly during 15 months. We compared dietary risk factors for kwashiorkor with those of marasmus. Kwashiorkor was diagnosed as pitting oedema of the ankles; marasmus as abnormal visibility of skeletal structures and palpable wasting of the gluteus muscle. A 24-h recall was administered 3-monthly to record the consumption of the 41 locally most frequent food items. We specified Hanley–Miettinen smooth-in-time risk models containing potential causal factors, including food items, special meals prepared for the child, breastfeeding, disease status, nutritional status, birth rank, age, season and number of meals. Bayesian Information Criteria identified the most plausible causal model of why some children developed kwashiorkor. In a descriptive analysis of the diet at the last dietary assessment prior to development of kwashiorkor, the diet of children who developed kwashiorkor was characterized by low consumption of sweet potatoes, papaya and “other vegetables” [0.0% , 2.3% (95% CI [0.4, 12.1] and 2.3% (95% CI [0.4, 12.1

    Introduction Paediatric respiratory tract infections (RTIs) are common reasons for primary care consultations and antibiotic prescribing. Locally relevant syndromic and microbiological surveillance information has the potential to improve the care of children with RTIs by normalising illness (parents) and reducing uncertainty (clinicians). Currently, most RTI studies are conducted at the point of healthcare service consultation, leaving the community burden, microbiology, symptom duration and proportion consulting largely unknown. This study seeks to establish the feasibility of (mainly online) participant recruitment and retention, and the acceptability/comparability of parent versus nurse-collected microbiological sampling, to inform the design of a future surveillance intervention study. Evidence regarding consultation rates and symptom duration is also sought. Methods and analysis A community-based, feasibility prospective inception cohort study, recruiting children aged ≥3 months and rates. Feasibility will be assessed using recruitment and retention rates, data completeness; and acceptability by quantitative survey and qualitative interviews. Symptomatic parent and nurse swab pairs will be compared for microbe isolation. PMID:27580839

Bayesian Information Criteria identified the most plausible causal model of why some children developed kwashiorkor. In a descriptive analysis of the diet at the last dietary assessment prior to development of kwashiorkor, the diet of children who developed kwashiorkor was characterized by low consumption of sweet potatoes, papaya and "other vegetables" [0.0% , 2.3% (95% CI [0.4, 12.1]) and 2.3% (95% CI [0.4, 12.1])] in comparison with children who did not develop kwashiorkor [6.8% (95% CI [6.4, 7.2]), 15.5% (95% CI [15, 16.1]) and 15.1% (95% CI [14.6, 15.7])] or children who developed marasmus [4.5% (95% CI [2.6, 7.5]) 11.8% (95% CI [8.5, 16.0]) and 17.6% (95% CI [13.7, 22.5])]. Sweet potatoes and papayas have high β-carotene content and so may some of "the other vegetables". We found that a risk model containing an age function, length/height-for age Z-score, consumption of sweet potatoes, papaya or other vegetables, duration of this consumption and its interaction term, was the most plausible

    2014-01-01

    Full Text Available The vascularity of placental tissue is dependent on various factors of which fetomaternal hypoxia plays a major role. Hypoxia can be of different types and each type influences the vascularity of the villi, especially terminal villi, in its own way. In this study, we attempted to identify villous vascular changes in a group of term placentae from mothers with diseases complicating pregnancy. Chorangiosis was the most frequently identified lesion while chorangioma was found in only 2 cases. There were no cases of chorangiomatosis. A few cases had normal villous vasculature. Maternal diseases have a major role in disrupting the placental vasculogenesis and angiogenesis by creating a hypoxic environment that may affect the fetus adversely. Hence, such conditions need to be identified early in pregnancy and managed appropriately as it is possible to maintain a normal vasculature and prevent neonatal mortality and morbidity if prompt intervention is done.

    Limb amputation is followed by stump and phantom pain in a large proportion of amputees and postamputation pain may be associated with signs of hyperexcitability such as hyperalgesia to mechanical stimulation. The present study examined the possible relationship between mechanical pain threshold of...... the limb and early (after 1 week) and late (after 6 months) phantom pain. Thirty-five patients scheduled for amputation of the lower limb were examined before, 1 week and 6 months after amputation. On all three examination days pressure-pain thresholds were measured and compared with the simultaneous...... amputation there was a significant and inverse relationship between mechanical thresholds and phantom pain but no relationship was found after 6 months. The findings suggest that although tenderness of the limb before and after amputation is related to early stump and phantom pain, the relationship is weak...

    Deepak R. Chavan

    2014-06-01

    Results: 128 patients aged 60 years or more who presented with abdominal emergency surgical conditions were studied. Most common cause for emergency abdominal surgery was perforated peptic ulcer (38% followed by intestinal obstruction (17%. The most common post-operative complication was surgical site infection (29%. Mortality rate was 17%. Most common cause of death was septic shock with multi organ dysfunction. Conclusion: Geriatric population is an important subgroup of population undergoing emergency abdominal surgeries. Most common cause is peptic ulcer perforation followed by intestinal obstruction due to adhesions. More than the age per say, the delay in presentation may be the cause for mortality in this age group. The therapeutic outcome in patients with co morbid factors like hypertension and diabetes mellitus in control, were similar to other patients. [Int J Res Med Sci 2014; 2(3.000: 963-971

    2005-01-01

    Aim: To evaluate the diagnostic value of the 10 systematic transrectal ultrasound-guided (TRUS) prostate biopsy compared with the sextant biopsy technique for patients with suspected prostate cancer. Methods: One hundred and fifty-two patients with suspected prostate cancer were included in the study. Patients were entered in the study because they presented with high levels of prostate specific antigen (PSA) (over 4 ng/mL) and/or had undergone an abnormal digital rectal examination (DRE). In addition to sextant prostate biopsy cores, four more biopsies were obtained from the lateral peripheral zone with additional cores from each suspicious area revealed by transrectal ultrasound. Sextant, lateral peripheral zone and suspicious area biopsy cores were submitted separately to the pathological department. Results: Cancer detection rates were 27.6% (42/152) and 19.7% (30/152) for the 10-core and sextant core biopsy protocols, respectively. Adding the lateral peripheral zone (PZ) to the sextant prostate biopsy showed a 28.6% (12/42) increase in the cancer detection rate in patients with positive prostate cancer (P < 0.01).The cancer detection rate in patients who presented with elevated PSA was 29.3% (34/116). When serum PSA was 4-10 ng/mL TRUS-guided biopsy detected cancer in 20.6%, while the detection rate was 32.4% and 47.0% when serum PSA was 10-20 ng/mL and above 20 ng/mL, respectively. Conclusion: The 10 systematic TRUS-guided prostate biopsy improves the detection rate of prostate cancer by 28.6% when compared with the sextant biopsy technique alone, without increase in the morbidity. We therefore recommend the 10-core biopsy protocol to be the preferred method for early detection of prostate cancer.

    2005-01-01

    Full Text Available Introduction The aim of this study was to investigate the most important etiological factors related to traumatic dental injuries, type of required treatment, period from injury to initial treatment and Frequency of recall appointments. Material and methods The sample consisted of 283 children with dental injuries managed at the Department of Dentistry of the Faculty of Medicine in Novi Sad. during the last 7 years. Retrospective data relied on trauma protocols of this department, whereas collected data referred to etiological factors, type of initial treatment, period from injury to initial treatment, recall appointments and complications of traumatic dental injuries. These results were compared with other similar national and international studies, in order to promote implementation of preventive strategies that would reduce the increasing frequency of dental trauma. Results Fall accidents were the most common cause of dental trauma. Injuries were most frequent in autumn, in the street, and in the afternoon hours. Single tooth injury was predominant, while the injured mostly denied previous injuries. Almost half of the injured patients did not seek professional help in the first 24 hours after the injury. 40% of treated patients missed their recall appointment. Conclusion Knowledge of the etiology is important for planning preventive, measures, but because of the complexity of etiological factors, it is difficult to prevent traumatic dental injuries. It is also important to underline the importance of immediate initial treatment of traumatized patients, and significance of their regular professional supervision. Generally speaking, almost all treatment procedures in management of traumatic dental injuries include preventive component.

  7. Prospects of photon counting lidar for savanna ecosystem structural studies

    Gwenzi, D.; Lefsky, M. A.

    2014-11-01

    Discrete return and waveform lidar have demonstrated a capability to measure vegetation height and the associated structural attributes such as aboveground biomass and carbon storage. Since discrete return lidar (DRL) is mainly suitable for small scale studies and the only existing spaceborne lidar sensor (ICESat-GLAS) has been decommissioned, the current question is what the future holds in terms of large scale lidar remote sensing studies. The earliest planned future spaceborne lidar mission is ICESat-2, which will use a photon counting technique. To pre-validate the capability of this mission for studying three dimensional vegetation structure in savannas, we assessed the potential of the measurement approach to estimate canopy height in a typical savanna landscape. We used data from the Multiple Altimeter Beam Experimental Lidar (MABEL), an airborne photon counting lidar sensor developed by NASA Goddard. MABEL fires laser pulses in the green (532 nm) and near infrared (1064 nm) bands at a nominal repetition rate of 10 kHz and records the travel time of individual photons that are reflected back to the sensor. The photons' time of arrival and the instrument's GPS positions and Inertial Measurement Unit (IMU) orientation are used to calculate the distance the light travelled and hence the elevation of the surface below. A few transects flown over the Tejon ranch conservancy in Kern County, California, USA were used for this work. For each transect we extracted the data from one near infrared channel that had the highest number of photons. We segmented each transect into 50 m, 25 m and 10 m long blocks and aggregated the photons in each block into a histogram based on their elevation values. We then used an expansion window algorithm to identify cut off points where the cumulative density of photons from the highest elevation resembles the canopy top and likewise where such cumulative density from the lowest elevation resembles mean ground elevation. These cut off

  9. Prospective study of muon storage rings at CERN

    Muon storage rings and colliders are reviewed. Their outstanding technical issues are outlined, and ways in which the CERN site and infrastructure could be used in their construction are discussed. A three-step scenario is proposed, starting with muon storage rings used primarily as sources for neutrino oscillation studies, continuing with intermediate-energy colliders to explore with precision new particles associated with electroweak symmetry breaking, and including a high-energy frontier machine with a centre-of-mass energy of several TeV. The charge and flavour separation of neutrinos from the decays of stored muons, coupled with their accurately known energy spectra and fluxes, would enable definitive long-, medium- and short-baseline neutrino experiments. The precision intermediate-energy muon colliders have the potential advantages of non-universal Higgs couplings, small energy spread and accurate energy calibration using the decays of polarized muons. A high-energy muon collider offers an attractive way of attaining effective multi-TeV energies in the centre of mass, but neutrino radiation must be controlled if this potential is to be realized fully.

    2014-06-01

    Full Text Available : INTRODUCTION: Ocular trauma is the leading cause of unilateral blindness all over the world.[1] The incidence of ocular trauma varies in different parts of the world. From India, the reported incidence is 20.53%.[2] Any strategy for prevention requires knowledge of the cause of injury, which may enable more appropriate targeting of resources towards preventing such injuries.[3] Eye trauma represents a large, potentially preventable burden on both victims and society as a whole. Traumatic cataracts occur secondary to blunt or penetrating ocular trauma, Infrared energy (glass-blower's cataract, electric shock and ionizing radiation are other rare causes of traumatic cataracts.[4] It form a separate category of cataracts as they present with other ocular morbidity like corneal tears, iris injury, vitreous hemorrhage and retinal tears; and they are to some extent, preventable. The methods used to evaluate the visual outcome in eyes managed for traumatic cataracts and senile cataracts are similar, but the damage to other ocular tissues owing to trauma may compromise the visual gain in eyes treated surgically for traumatic cataracts.[5] Hence, the success rates may differ between eyes with these two types of cataract. The aim of this study was to evaluate the final visual outcome of a patient with surgical extraction of traumatic cataract along with demographic features and modes of trauma.

    2012-06-01

    Full Text Available Background: Adverse reactions to intravenous iodinated contrast media may be classified as general and organ-specific, such as contrast-induced nephrotoxicity. General adverse reactions may be sub classified into acute and delayed types. Acute general adverse reactions can range from transient minor reactions to life-threatening severe reactions. This study was done to determine clinical adverse effects of the iodinated contrast media. Methods: Data of 899 consecutive patients at C.U. Shah Medical College and Hospital, Surendranagar, who received sodium meglumine diatrizoate intravenous iodinated contrast media during the period of May 2011 to April 2012, were collected for any adverse drug reactions. Results: Out of 899, 189 patients developed adverse contrast reactions. The incidences of mild, moderate and severe adverse reactions were 19.47%, 1.33% and 0.28%, respectively. There were no differences in the incidence of adverse reactions according to gender (males 21.1%; females 20.7%; p= >0.05 or age (p= >0.05. The incidence of adverse reactions was significantly higher in patients with a history of previous reactions (50% than in those with no history (21.25%; p= <0.05. Conclusions: The skin was the most commonly affected site of reactions. In reactions, mild forms were more common compared to moderate and severe. [Int J Basic Clin Pharmacol 2012; 1(3.000: 211-215

  12. Dieting and food craving. A descriptive, quasi-prospective study.

    Massey, Anna; Hill, Andrew J

    2012-06-01

    Evidence linking food restriction and food craving is equivocal. This study investigated whether dieting was associated with a greater frequency of food craving. Dieting to lose weight was distinguished from watching so as not to gain weight. Participants were 129 women (mean age=41 yrs): 52 were currently dieting to lose weight, 40 were watching their weight, and 37 were non-dieters. They completed a food craving record after every food craving, a food diary, and a daily mood assessment over 7-days. Of the 393 craving incidents recorded, dieters experienced significantly more food cravings than non-dieters, with watchers intermediate. Chocolate was the most craved food (37% of cravings) but neither the types of food, the proportion of cravings leading to eating (∼70%), the situations in which cravings occurred, nor the time since the last eating episode differed between groups. Compared with non-dieters, dieters experienced stronger cravings that were more difficult to resist, and for foods they were restricting eating. Watchers showed similarities in experience both to dieters (low hunger) and non-dieters (lower craving intensity). These results support an association between dieting and food craving, the usefulness of distinguishing dieting to lose weight and watching, and suggest a need for further experimental investigation of actual food restriction on food craving experiences.

    1999-09-01

    Full Text Available Acute amniotic fluid infection has emerged as a possible cause of many heretofore unexplained preterm births. Our purpose was to determine the effect of ampicillin in the prolongation of pregnancies receiving tocolysis for preterm labor. A blinded, placebo-controlled, randomized trial was conducted to study ampicillin in women hospitalized for preterm labor between 24 and 37 weeks' gestation. A total of 60 patients with intact membranes and without chorioamnionitis who were receiving magnesium sulfate were screened. Thirty women with preterm labor received ampicillin, and 30 received placebos. The primary end point was prolongation of gestation. There was no difference in age of delivery (37.6±9.7 days vs 36.08±3.9 days, P=0.085 and no difference in retardation of delivery (4.7±3.1 vs 4.1±2.1, P=0.39. The mean degree of preterm delivery were 0.62±1.93 and 1.8±3.3 weeks in ampicillin and placebo groups, respectively (not significant, P>0.1. Conclusions: Ampicillin had no effect on interval to delivery or duration of pregnancy in women treated for preterm labor. So rotine clinical use of ampicillin during tocolysis should not be recommended.

    2011-05-01

    Full Text Available Abstract Background Death rates are notably higher in eastern Finland than in western Finland, and life expectancy of Finnish speakers shorter than that of Swedish speakers. The mortality differences correspond to recent genetic mappings of the population and are prominent for causes of death that are known to be associated with genetic risk factors. Methods Using intergenerational data, we studied the impact of parental birth area on all-cause mortality risks of middle-aged men in Finland 1985-2003, assuming that geographic family origin reflects genetic predisposition to complex disorders. Relative death risks at ages 30-49 years were estimated by parental birth region and ethnicity, according to Cox regressions standardised for own education, family type at childhood, and year of birth. Results The death risk of Finnish speakers born in eastern Finland was 1.13 (95% confidence interval 1.01 to 1.26 that of Finnish speakers born in western Finland, whereas that of Swedish speakers was only 0.60 (0.52 to 0.71. In Finnish speakers, the effects of own birth area and area of residence disappeared when parental birth area was accounted for. The death risk of persons with at least one parent born in eastern Finland was 1.23 (1.09 to 1.39 that of people with both parents born in western Finland. Conclusions Parental birth area is the driving force behind the regional mortality difference in Finland. The findings highlight and give further support for the potentially important role of genetic risk factors in mortality. Close monitoring of persons' geographic and ethnic ancestry may promote public health and avoid many early deaths.

    Full Text Available : BACKGROUND: Low back pain (LBP is a common presenting complaint affecting mostly middle aged and older person and traditionally considered as ageing process, but now-a-days large number of younger people are also affected by this debilitating chronic disorder. The cause of early onset of degenerative spine disease is multifactorial, but genetical predisposition plays very important role. AIMS AND OBJECTIVE: To find out association between genetic predisposition and degenerative spine disease in adult patients and to assess the pattern of MRI findings of various degenerative diseases in lumbo-sacral spine. MATERIAL AND METHOD: The present cross-sectional study had been performed among 100 selected patients in 1yr period, who presented with chief complaint of chronic low back pain. After taking detailed clinical and professional history, MRI of lumbosacral spine had been performed. Total 100 patients were divided in two groups on the basis of genetical predisposition. Prevalence and spectrum of degenerative changes were compared between both groups. RESULTS: Hundred patients of 20 to 35-year age had been selected with mean age of 27yr. Out of 100 patients; 47 were male and 53 were female. The most common degenerative findings were desiccation of disc (95% followed by disc bulge, herniation, spinal canal stenosis, ligamentum flavum hypertrophy, facet joint hypertrophy and modic changes. L4-L5 and L5- S1 were the most commonly involved spinal levels for any degenerative pathology. CONCLUSION: Good association is seen between early onset of degenerative spine disease and genetical predisposition in patients who have history of similar type degenerative spine disease in one or more first degree relatives in comparison to those patients who do not have any genetical predisposition. So it can be concluded that heredity play important role in early onset of degenerative spine disease in adults.

    Full Text Available Background and Design: The definition of emergent diseases includes potentially risky diseases that need urgent medical intervention. Diagnostic and therapeutic processes are managed mostly at ourpatient setting in dermatology. Therefore, it is unclear that which diseases are real emergencies and which patients apply urgently. There are a few studies assessing this topic. Our aim was to evaluate patients referred to our clinic urgently, and to review the concept of ‘‘real dermatologic emergency’’ by comparing dermatologic emergency patients and outpatients. Material and Method: A total of 800 patients (400 urgent patients, 400 outpatients were included. Demographic features, complaints, disease duration and severity, whether the disease occurs for the first time were questionned, application time and diagnosis were recorded. The opinions of patients and physicians were inquired about why they thought that the disease was emergent. Results: Most common skin diseases were acute urticaria-angioedema, contact dermatitis, and insect bite in emergency patients; acne vulgaris, verruca and tinea pedis in outpatients. Itching was more common in emergency patients. Emergency patients' complaints were more severe than those of outpatients. Patients who experience disease first time applied to emergency service more than others. Emergency patients had a shorter disease duration than outpatients. Patients and physicians revealed different reasons and criteria about the urgency of the diseases. 93.5% of patients and 49% of physicians thought that existing disease was emergent. Conclusion: Our data reveal that the concept of dermatologic emergency is unsettled. It changes according to socio-cultural, personal features and to the present health system. Determination of the main criteria of the definition of “dermatologic urgent”, and training of dermatologists, emergency centers’physicians and also of patients in this regard seem to be a necessity

    2009-07-01

    Full Text Available Abstract Background Adverse psychosocial work environments may lead to impaired mental health, but it is still a matter of conjecture if demonstrated associations are causal or biased. We aimed at verifying whether poor psychosocial working climate is related to increase of redeemed subscription of antidepressant medication. Methods Information on all antidepressant drugs (AD purchased at pharmacies from 1995 through 2006 was obtained for a cohort of 21,129 Danish public service workers that participated in work climate surveys carried out during the period 2002–2005. Individual self-reports of psychosocial factors at work including satisfaction with the work climate and dimensions of the job strain model were obtained by self-administered questionnaires (response rate 77,2%. Each employee was assigned the average score value for all employees at his/her managerial work unit [1094 units with an average of 18 employees (range 3–120]. The risk of first-time AD prescription during follow-up was examined according to level of satisfaction and psychosocial strain by Cox regression with adjustment for gender, age, marital status, occupational status and calendar year of the survey. Results The proportion of employees that received at least one prescription of ADs from 1995 through 2006 was 11.9% and prescriptions rose steadily from 1.50% in 1996 to the highest level 6.47% in 2006. ADs were prescribed more frequent among women, middle aged, employees with low occupational status and those living alone. None of the measured psychosocial work environment factors were consistently related to prescription of antidepressant drugs during the follow-up period. Conclusion The study does not indicate that a poor psychosocial work environment among public service employees is related to prescription of antidepressant pharmaceuticals. These findings need cautious interpretation because of lacking individual exposure assessments.
