    We performed a multicenter prospective observational cohort study (Epidémiologie et Pronostic de l'Insuffisance Cardiaque Aiguë en Lorraine, Epidemiology and Prognosis of Acute Heart Failure in Lorraine [EPICAL2]) to evaluate the effectiveness on mortality of a community-based multidisciplinary disease management programme (DMP) for heart failure (HF) patients.Between October 2011 and October 2012, 1816 patients, who were hospitalized for acute HF or who developed acute HF during a hospitalization, were included from 21 hospitals in a northeast region of France. At hospital admission, their mean age was 77.3 (standard deviation [SD] 11.6) years and mean left ventricular ejection fraction was 45.0 (SD 16.0)%. A subset of patients were enrolled in a multidimensional DMP for HF (n = 312, 17.2%), based on structured patient education, home monitoring visits by HF-trained nurses, and automatic alerts triggered by significant clinical and biological changes to the patient. The DMP involved general practitioners, nurses, and cardiologists collaborating via an individual web-based medical electronic record. The outcome was all-cause mortality from the 3rd to the 12th month after discharge. During the follow-up, a total of 377 (20.8%) patients died: 321 (21.3%) in the control group and 56 (17.9%) in the DMP group. In a propensity score analysis, DMP was associated with lower 1-year all-cause mortality (hazard ratio 0.65, 95% CI 0.46-0.92). Instrumental variable analysis gave similar results (hazard ratio 0.56, 0.27-1.16).In a real world setting, a multidimensional DMP for HF with structured patient education, home nurse monitoring, and appropriate physician alerts may improve survival when implemented after discharge from hospitalization due to worsening HF.

    Falls can have devastating consequences for older people. We determined the relationship between the likelihood of fall incidents and daily-life behavior. We used wearable sensors to assess habitual physical activity and daily-life gait quality (in terms of e.g. stability, variability, smoothness and symmetry), and determined their predictive ability for time-to-first-and-second-falls. 319 older people wore a trunk accelerometer (Dynaport MoveMonitor, McRoberts) during one week. Participants further completed questionnaires and performed grip strength and trail making tests to identify risk factors for falls. Their prospective fall incidence was followed up for six to twelve months. We determined interrelations between commonly used gait characteristics to gain insight in their interpretation and determined their association with time-to-falls. For all data -including questionnaires and tests- we determined the corresponding principal components and studied their predictive ability for falls. We showed that gait characteristics of walking speed, stride length, stride frequency, intensity, variability, smoothness, symmetry and complexity were often moderately to highly correlated (r > 0.4). We further showed that these characteristics were predictive of falls. Principal components dominated by history of falls, alcohol consumption, gait quality and muscle strength proved predictive for time-to-fall. The cross-validated prediction models had adequate to high accuracy (time dependent AUC of 0.66-0.72 for time-to-first-fall and 0.69-0.76 for -second-fall). Daily-life gait quality obtained from a single accelerometer on the trunk is predictive for falls. These findings confirm that ambulant measurements of daily behavior contribute substantially to the identification of elderly at (high) risk of falling.

    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 (PET{sub 1}). All included patients had a FDG PET/CT scan during RT (PET{sub 2}, 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 SUV{sub max} in the PET{sub 2} 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 < 10{sup -4}). A SUV{sub max} value of 5.3 in the PET{sub 2} 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 SUV{sub max} assessed during the 5th week of curative-intent RT or RCT in NSCLC patients (NCT01261598; RTEP2 study).

    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.

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.)

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

    Full Text Available OBJECTIVE: To study the treatment patterns and visual outcome over one year in Asian patients with choroidal neovascular membrane secondary to age-related macular degeneration (AMD-CNV and polypoidal choroidal vasculopathy (PCV. 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. There were no significant differences in visual outcome between AMD-CNV and PCV (p = 0.51. Factors predictive of month 12 visual outcome were baseline VA, baseline OCT central macular thickness, month 3 VA and age. CONCLUSIONS: There is significant variation in treatment patterns in Asian eyes with exudative maculopathy. There is significant visual improvement in all treatment groups at one year. These data highlight the need for high quality

    Peter Van den Eede

    Full Text Available BACKGROUND: There is an increasing body of literature reporting treatment failure of the currently recommended radical treatment of Plasmodium vivax infections. As P. vivax is the main malaria species outside the African continent, emerging tolerance to its radical treatment regime could have major consequences in countries like Peru, where 80% of malaria cases are due to P. vivax. Here we describe the results of a 1-year longitudinal follow up of 51 confirmed P. vivax patients living around Iquitos, Peruvian Amazon, and treated according to the Peruvian national guidelines. METHODOLOGY: Each month a blood sample for microscopy and later genotyping was systematically collected. Recent exposure to infection was estimated by detecting antibodies against the P. vivax circumsporozoite protein (CSP and all PCR confirmed P. vivax infections were genotyped with 16 polymorphic microsatellites. RESULTS: During a 1-year period, 84 recurrent infections, 22 positive also by microscopy, were identified, with a median survival time to first recurrent infection of 203 days. Most of them (71% were asymptomatic; in 13 patients the infection persisted undetected by microscopy for several consecutive months. The genotype of mostly recurrent infections differed from that at day 0 while fewer differences were seen between the recurrent infections. The average expected heterozygosity was 0.56. There was strong linkage disequilibrium (I(A(s = 0.29, p<1.10(-4 that remained also when analyzing only the unique haplotypes, suggesting common inbreeding. CONCLUSION: In Peru, the P. vivax recurrent infections were common and displayed a high turnover of parasite genotypes compared to day 0. Plasmodium vivax patients, even when treated according to the national guidelines, may still represent an important parasite reservoir that can maintain transmission. Any elimination effort should consider such a hidden reservoir.

  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.

    Background: The presence of keratinized tissue around dental implants is more than desirable either from a functional and aesthetic point of view, making soft tissue grafting a common practice in implant rehabilitation. Autogenous soft tissue grafting procedures are usually associated with high morbidity. Aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants. Methods: 15 consecutive patients underwent a vestibuloplasty and grafting, both in the mandible and the maxilla, with a collagen matrix. Results: The primary endpoint was to evaluate the resorption of the graft along with the re-epithelization grafted area. The percentage of the resorption was 44,4%, with a mean gain in vestibular height of 3 mm. Secondary endpoints evaluated the clinical appearance, the hemostatic effect and the post-operative pain. All subjects referred minimal pain with no bleeding. No adverse reaction nor infection were noted. Conclusion: This study showed that the used collagen matrix can find major interest in those patients who need a greater aesthetic outcome as the matrix has a perfect integration with the surrounding tissues. Furthermore it is strongly recommended for those patients who can bear little pain. Clinical Significance: Post-operative morbidity of autologous grafts is the biggest concern of this type of surgery. The possibility to use a soft tissue substitute is a great achievement as morbidity decreases and bigger areas can be treated in a single surgery. The present study showed the efficacy of a collagen matrix as this kind of substitute. PMID:27583050

    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.

    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

    Neck pain is more prevalent in office workers than in the general community. To date, findings from prospective studies that investigated causal relationships between putative risk factors and the onset of neck pain in this population have been limited by high loss to follow-up. The aim of this research was to prospectively evaluate a range of risk factors for neck pain in office workers, using validated and reliable objective measures as well as attain an estimate of 1-year incidence. We assembled a cohort of 53 office workers without neck pain and measured individual, physical, workplace and psychological factors at baseline. We followed participants for 1 year to measure the incidence of neck pain. We achieved 100% participant follow-up. Cox regression analysis was applied to examine the relationship between the putative risk factors and the cumulative incidence of neck pain. The 1-year incidence proportion of neck pain in Australian office workers was estimated in this study to be 0.49 (95% CI 0.36-0.62). Predictors of neck pain with moderate to large effect sizes were female gender (HR: 3.07; 95% CI: 1.18-7.99) and high psychological stress (HR: 1.64; 95% CI: 0.66-4.07). Protective factors included increased mobility of the cervical spine (HR: 0.44; 95% CI: 0.19-1.05) and frequent exercise (HR: 0.64; 95% CI: 0.27-1.51). These results reveal that neck pain is common in Australian office workers and that there are risk factors that are potentially modifiable.

    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

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

    International Nuclear Information System (INIS)

    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

    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

    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.

    Full Text Available This study aims to identify the predictors in the different aspects of the health-related quality of life (HRQoL and to measure the changes of functional status over time in a cohort of Nigerian stroke survivors. A prospective observational study was conducted in three hospitals of Kano state of Nigeria where stroke survivors receive rehabilitation. The linguistic-validated Hausa versions of the stroke impact scale 3.0, modified Rankin scale, Barthel index and Beck depression inventory scales were used. Paired samples t-test was used to calculate the amount of changes that occur over time and the forward stepwise linear regression model was used to identify the predictors. A total of 233 stroke survivors were surveyed at 6 months, and 93% (217/233 were followed at 1 year after stroke. Functional disabilities were significantly reduced during the recovery phase. Motor impairment, disability, and level of depression were independent predictors of HRQoL in the multivariate regression analysis. The involvement of family members as caregivers is the key factor for those survivors with improved functional status. Thus, to enhance the quality of poststroke life, it is proposed that a holistic stroke rehabilitation service and an active involvement of family members are established at every possible level.

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

    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.

    OBJECTIVE The purpose of this study was to investigate white matter (WM) structural abnormalities using diffusion tensor imaging (DTI) in children with hydrocephalus before CSF diversionary surgery (including ventriculoperitoneal shunt insertion and endoscopic third ventriculostomy) and during the course of recovery after surgery in association with neuropsychological and behavioral outcome. METHODS This prospective study included 54 pediatric patients with congenital hydrocephalus (21 female, 33 male; age range 0.03-194.5 months) who underwent surgery and 64 normal controls (30 female, 34 male; age range 0.30-197.75 months). DTI and neurodevelopmental outcome data were collected once in the control group and 3 times (preoperatively and at 3 and 12 months postoperatively) in the patients with hydrocephalus. DTI measures, including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) values were extracted from the genu of the corpus callosum (gCC) and the posterior limb of internal capsule (PLIC). Group analysis was performed first cross-sectionally to quantify DTI abnormalities at 3 time points by comparing the data obtained in the hydrocephalus group for each of the 3 time points to data obtained in the controls. Longitudinal comparisons were conducted pairwise between different time points in patients whose data were acquired at multiple time points. Neurodevelopmental data were collected and analyzed using the Adaptive Behavior Assessment System, Second Edition, and the Bayley Scales of Infant Development, Third Edition. Correlation analyses were performed between DTI and behavioral measures. RESULTS Significant DTI abnormalities were found in the hydrocephalus patients in both the gCC (lower FA and higher MD, AD, and RD) and the PLIC (higher FA, lower AD and RD) before surgery. The DTI measures in the gCC remained mostly abnormal at 3 and 12 months after surgery. The DTI abnormalities in the PLIC were

    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

    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.

    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.

    Eighty patients, of whom 22 were men and 58 women, participated in a 1-year follow-up study. All participants in the study showed signs and symptoms of craniomandibular disorders (CMD) and had had pain for more than 6 months at treatment start. The patients were randomly assigned to either acupuncture or occlusal splint therapy. Those patients who did not respond to either of the treatment modes were offered various additional therapies. The result showed that 57% of the patients who received acupuncture and 68% of the patients treated with occlusal splint therapy benefited subjectively (p < 0.01) and clinically (p < 0.001) from the treatment over a 12-month period. No statistically significant difference was found between the two groups as to the assessment variables. Those patients who received various additional therapies after acupuncture and/or occlusal splint therapy responded favorably to additional treatment in only a few instances. The study showed that acupuncture gave positive results similar to those of occlusal splint therapy in patients with primarily myogenic CMD symptoms over a 1-year follow-up period.

    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.

    Contamination of hot water distribution systems by Legionella represents a great challenge due to difficulties associated with inactivating microorganisms, preserving the water characteristics. The aim of this study was to examine over the course of 1 year in 11 fixed sites, the impact of monochloramine disinfection on Legionella, heterotrophic bacteria (36 °C), Pseudomonas aeruginosa contamination, and chemical parameters of a plumbing system in an Italian hospital. Three days after installation (T0), in the presence of monochloramine concentration between 1.5 and 2 mg/L, 10/11 sites (91%) were contaminated by L. pneumophila serogroups 3 and 10. After these results, the disinfectant dosage was increased to between 6 and 10 mg/L, reducing the level of Legionella by three logarithmic unit by 2 months postinstallation (T2) until 6 months later (T3). One year later (T4), there was a significant reduction (p = 0.0002) at 8/11 (73%) sites. Our data showed also a significant reduction of heterotrophic bacteria (36 °C) in 6/11 (55%) sites at T4 (p = 0.0004), by contrast the contamination of P. aeruginosa found at T0 in two sites persisted up until T4. The results of the present study show that monochloramine is a promising disinfectant that can prevent Legionella contamination of hospital water supplies.

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.

    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.

    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.

    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.

    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

    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.

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.

    2008-07-28

    To evaluate in a twelve-month, randomized placebo-controlled study whether pure administration of phytoestrogen genistein (54 mg/day) might reduce cytogenetic biomarkers in peripheral lymphocytes of postmenopausal women. A total of 57 postmenopausal women met the criteria and were randomly assigned to receive phytoestrogen genistein (n = 30) or placebo (n = 27). There was no significant difference in age, length of time since menopause or body mass index between the two groups. After one year, plasma genistein level was 0.14 +/- 0.01 micromol/L in the control group and 0.72 +/- 0.08 micromol/L in the genistein group (P < 0.0001). At baseline, sister chromatid exchange rate was 4.97 +/- 2.17 in the control group and 4.96 +/- 1.83 in the genistein group (P = 0.89). After one year, sister chromatid exchange rate was 4.96 +/- 2.16 in the control group and 3.98 +/- 1.14 in the genistein group (P < 0.05). High frequency cells count was 3% in the genistein group and 5% in the control group (P < 0.05) at the end of the study. Chromosomal aberration frequency was 5.55% in the control group at time 0 and 5.75% in the genistein group; after one year, the figures were 5.86% in the control group and 4.5% in the genistein group (P < 0.05). After one year, there was a negative relationship between sister chromatid exchange rate and plasma levels (r = - 0.43; P < 0.05) in the genistein group. Phytoestrogen genistein has been shown in postmenopausal women to be effective in the reduction of cytogenetic biomarkers. The protective effect on genomic damage appears to be a particularly promising tool in reducing the risk of cancer.

  18. EPR Dosimetry: an update and prospective studies

    International Nuclear Information System (INIS)

    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)

    We conducted a one-year prospective study involving a prehospital Emergency Medical Service in the Netherlands to investigate the incidence of failed or difficult prehospital endotracheal intubation. During the study period the paramedics were asked to fill in a registration questionnaire after every endotracheal intubation. Of the 26,271 patient contacts, 256 endotracheal intubations were performed by paramedics in one year. Endotracheal intubation failed in 12 patients (4.8%). In 12.0% of 249 patients, a Cormack and Lehane grade III laryngoscopy was reported and a grade IV laryngoscopy was reported in 10.4%. The average number of endotracheal intubations per paramedic in one year was 4.2 and varied from zero to a maximum of 12. The median time between arrival on the scene and a positive capnograph was 7 min.38 s in the case of a Cormack and Lehane grade I laryngoscopy and 14 min.58 s in the case of a Cormack and Lehane grade 4 laryngoscopy. The incidence of endotracheal intubations performed by Dutch paramedics in one year was low, but endotracheal intubation was successful in 95.2%, which is comparable with findings in international literature. Early capnography should be used consistently in prehospital airway management. PMID:21612142

    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.

    Background: Africa has very few neurosurgeons. These are almost exclusively in urban centers. Consequently, people in rural areas, most of the African population, have poor or no access to neurosurgical care. We have recently pioneered rural neurosurgery in Nigeria. Objectives: This report details our initial experiences and the profile of neurosurgical admissions in our center. Methods: A prospective observational study of all neurosurgical patients managed at a rural tertiary health institution in Nigeria from December 2010 to May 2012 was done. Simple descriptive data analysis was performed. Results: A total of 249 males (75.2%) and 82 females (24.8%) were managed. The median age was 37 years (range: Day of birth – 94 years). Trauma was the leading cause of presentation with 225 (68.0%) and 35 (10.6%) having sustained head and spinal injuries, respectively. Operative intervention was performed in 54 (16.3%). Twenty-four (7.2%) patients discharged against medical advice, mostly for economic reasons. Most patients (208, 63.4%) had satisfactory outcome while 30 (9.1%) died. Conclusion: Trauma is the leading cause of rural neurosurgical presentations. There is an urgent need to improve access to adequate neurosurgical care in the rural communities.

    A prospective study of pedalcycle accident morbidity and mortality was carried out from February to mid-November 1983 because of the high frequency of child cyclist injuries that were occurring on the relatively flat Redcliffe Peninsula. These injuries were apparently associated with the large number of young children who use a bicycle as their main mode of transport to and from school. The schools were surveyed for the extent of bicycle use and cyclists were surveyed for the amount of protective clothing that was worn while involved in cycling. It was found that a disturbingly large number of young children made regular bicycle trips on public roads with the minimal use of safety helmets or any other form of protective clothing. Nearly 40% of on-road accidents involved children of less than 12 years of age, and over 10% of these involved children of six years of age or less. No child in our series of on-road accidents was, at the time of injury, wearing a safety helmet or any other form of protective clothing. No bicycle accidents occurred on the exclusive cycle track of approximately 1 km in length on the Peninsula.

    Gastrectomy induces severe osteoporosis in humans but its quantitative scale within trabecular and cortical compartments was not estimated. The aim of the study was to determine changes of volumetric bone mineral density (vBMD) in lumbar vertebrae (L1-L4) and biochemical bone metabolism markers in serum of patients 1 year after total gastrectomy. The control group consisted of patients (N = 8) subjected to abdominal surgery due to cardiospasmus. Total gastrectomy was performed in the experimental group (N = 6). Volumetric bone mineral density of trabecular and cortical bone of lumbar spine was measured before (baseline) and 1 year after the gastric surgery using the quantitative computed tomography method. Serum concentrations of insulin, insulin-like growth factor-1, tyroxine, interleukin-6, C-terminal telopeptides of type II collagen and bone formation, and resorption markers were determined at baseline and 1 year later, using ELISA, EIA, and IEMA methods. Total gastrectomy induced significant decrease of vBMD values, up to 16.8% and 10.0%, within the trabecular and cortical bone compartments of lumbar spine (P < 0.05). These negative changes of vBMD were associated with significantly increased serum concentration of bone resorption markers such as deoxypyridinoline, pyridinoline, and C-terminal telopeptides of type I collagen, by 13.5%, 32.2%, and 121.5%, respectively (P < 0.05). Neither vBMD nor biochemical bone turnover markers and hormone concentrations were influenced in the control patients. Dramatic bone loss during the first year in gastrectomized patients has proven dynamic osteoporosis progress indicating an importance of treatment interventions in these patients with emphasis on inhibition of intensive bone resorption processes.

    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.

    Little is known about the factors associated with patient compliance with nucleos(t)ide analog (NUC) treatment for chronic hepatitis B (CHB). The purpose of this study was to examine the association between sociodemographic and clinical characteristics and adherence to NUCs among patients with CHB. A total of 211 CHB patients receiving NUC monotherapy were asked to report the number of prescribed doses of medication they had taken during the last 90 days. A total of four 3-month adherence scores were averaged to obtain a combined rate of NUC adherence during a 1-year follow up period. The mean age of the patients was 29.6 years, 79% were men, and 68% had no prior NUC treatment for CHB. Females, patients without a previous NUC treatment, and those who had NUC drug resistance showed better adherence to NUC treatment, and compliance was better with telbivudine than with lamivudine and entecavir.

    Full Text Available Aims: The aim of the following study is to evaluate the change in laser fluorescence (LF values for extracted teeth stored in different solutions over 1 year period, to give cut-off values for different storage media at different time intervals to get them at par with the in vivo conditions and to see which medium gives best results with the least change in LF values and while enhancing the validity of DIAGNOdent in research. Materials and Methods: Ninety extracted teeth selected, from a pool of frozen teeth, were divided into nine groups of 10 each. Specimens in Groups 1-8 were stored in 1% chloramine, 10% formalin, 10% buffered formalin, 0.02% thymol, 0.12% chlorhexidine, 3% sodium hypochlorite, a commercially available saliva substitute-Wet Mouth (ICPA Pharmaceuticals and normal saline respectively at 4°C. The last group was stored under frozen condition at −20°C without contact with any storage solution. DIAGNOdent was used to measure the change the LF values at day 30, 45, 60, 160 and 365. Statistical Analysis Used: The mean change in LF values in different storage mediums at different time intervals were compared using two-way ANOVA. Results: At the end of 1 year, significant decrease in fluorescence (P < 0.05 was observed in Groups 1-8. Maximum drop in LF values occurred between day 1 and 30. Group 9 (frozen specimens did not significantly change their fluorescence response. Conclusions: An inevitable change in LF takes place due to various storage media commonly used in dental research at different time intervals. The values obtained from our study can remove the bias caused by the storage media and the values of LF thus obtained can hence be conveniently extrapolated to the in vivo condition.

    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.

Its potential consequences, including reduced function and reduced social participation, are likely to be associated with decreased health-related quality of life (HRQoL. However, illness perceptions and self-efficacy beliefs may also play a part in determining HRQoL in persons with COPD. The aim of this study was to explore the relationships between illness perceptions, self-efficacy, and HRQoL in a sample of persons with COPD in a longitudinal perspective. The context of the study was a patient education course from which the participants were recruited. Data concerning sociodemographic variables, social support, physical activity, illness perceptions, general self-efficacy, and HRQoL were collected before the course started and 1 year after completion. Linear regression was used in the analyses. The results showed that less consequences and less symptoms (identity were associated with higher physical HRQoL (PCS at baseline and at 1-year follow-up. Less emotional response was similarly associated with higher mental HRQoL (MCS at both time points. Lower self-efficacy showed a borderline significant association with higher PCS at baseline, but was unrelated to MCS at both time points. Self-efficacy showed no influence on the associations

    Full Text Available Jie Peng, Junhua Yin, Shaohang Cai, Tao Yu, Chunxiu Zhong Nanfang Hospital, Southern Medical University, Guangzhou, Guangdong Province, People’s Republic of China Abstract: Little is known about the factors associated with patient compliance with nucleos(tide analog (NUC treatment for chronic hepatitis B (CHB. The purpose of this study was to examine the association between sociodemographic and clinical characteristics and adherence to NUCs among patients with CHB. A total of 211 CHB patients receiving NUC monotherapy were asked to report the number of prescribed doses of medication they had taken during the last 90 days. A total of four 3-month adherence scores were averaged to obtain a combined rate of NUC adherence during a 1-year follow up period. The mean age of the patients was 29.6 years, 79% were men, and 68% had no prior NUC treatment for CHB. Females, patients without a previous NUC treatment, and those who had NUC drug resistance showed better adherence to NUC treatment, and compliance was better with telbivudine than with lamivudine and entecavir.

    We reported an acute encephalitis syndrome outbreak in Alappuzha district in Kerala, India during the year 2011. The etiology was confirmed to be West Nile virus lineage 1. Many encephalitis patients from this outbreak exhibited neurological sequelae post recovery. This study was aimed to assess the clinical outcomes of West Nile encephalitis confirmed case-patients after 1 year of acute illness. Forty West Nile virus confirmed encephalitis patients were selected from the 2011 outbreak was included in this study. Out of 40 cases, only 30 survived after 12 months. Among these 30 recovered case-patients, 27 (90%) consented for clinical follow-up and 23 (73.67%) of them consented for assessment of cognitive impairment and deposition of blood sample for antibody testing. The most common symptom observed in these patients was fatigue (25.93%). Other symptoms included dizziness (7.4%), decreased sense of hearing (7.4%) and decreased sense of smell (7.4%). Reduced power in limbs was found in 33.33% of the cases. Most of the patients (23.1%) were dependent on others for normal daily living activities. The patients also had probable risk of poor cognition (29.41%) and dementia (57.14%). None of the patients were positive for WNV specific IgM at 12 months post onset of disease. The study concluded that the long-term sequelae were noticed in WNV positive patients. Prevention effort should be focused on the elderly (≥60 years old) people who have a higher risk of severe sequelae. The state health authorities should create awareness among people in order to prevent the transmission of disease. J. Med. Virol. 88:1856-1861, 2016. © 2016 Wiley Periodicals, Inc.

    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

    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.

    The personality systems of Cloninger (as measured by the Tridimensional Personality Questionnaire [TPQ]) and Eysenck (as measured by the Eysenck Personality Questionnaire [EPQ]) both have been linked to substance use and abuse. The current study examined the predictive utility of both systems for substance use disorder (SUD) diagnoses, both cross-sectionally and prospectively. Participants (N = 489 at baseline) completed the EPQ and TPQ and were assessed via structured diagnostic interview at baseline and 6 years later (N = 457 at follow-up). Both the EPQ and TPQ scales demonstrated bivariate cross-sectional and prospective associations with SUDs. Within each system, those dimensions marking a broad impulsive sensation-seeking or behavioral disinhibition trait were the best predictors prospectively, although the 2 systems were differentially sensitive to specific diagnoses. These relations remained significant even with autoregressivity, other concurrent SUD diagnoses, and multiple personality dimensions statistically controlled.

    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)

    Repeat episodes of infective endocarditis (IE) can occur in patients who survive an initial episode. We analysed risk factors and 1-year mortality of patients with repeat IE. We considered 1874 patients enrolled in the International Collaboration on Endocarditis - Prospective Cohort Study between January 2000 and December 2006 (ICE-PCS) who had definite native or prosthetic valve IE and 1-year follow-up. Multivariable analysis was used to determine risk factors for repeat IE and 1-year mortality. Of 1874 patients, 1783 (95.2%) had single-episode IE and 91 (4.8%) had repeat IE: 74/91 (81%) with new infection and 17/91 (19%) with presumed relapse. On bivariate analysis, repeat IE was associated with haemodialysis (p 0.002), HIV (p 0.009), injection drug use (IDU) (p < 0.001), Staphylococcus aureus IE (p 0.003), healthcare acquisition (p 0.006) and previous IE before ICE enrolment (p 0.001). On adjusted analysis, independent risk factors were haemodialysis (OR, 2.5; 95% CI, 1.2-5.3), IDU (OR, 2.9; 95% CI, 1.6-5.4), previous IE (OR, 2.8; 95% CI, 1.5-5.1) and living in the North American region (OR, 1.9; 95% CI, 1.1-3.4). Patients with repeat IE had higher 1-year mortality than those with single-episode IE (p 0.003). Repeat IE is associated with IDU, previous IE and haemodialysis. Clinicians should be aware of these risk factors in order to recognize patients who are at risk of repeat IE.

    The effects of impacted lower 3rd molar surgery on periodontal tissues in the adjacent 2nd molar area have been investigated in a prospective study comprising 176 cases from 2 age groups: less than or equal to 20 years (n = 93) and greater than or equal to 30 years (n = 83), respectively. The preoperative and 1-year postoperative examinations included both clinical and radiographic variables. All patients were subjected to a standardized surgical procedure and optimal plaque control pre-, intra- and postoperatively. Early removal of impacted lower 3rd molars with large angulation and close positional relationship to the adjacent 2nd molar proved to have a beneficial effect on periodontal health. PMID:2019777

    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).

    Full Text Available Management of intracranial aneurysms has made debates about the best treatment modality in recent years. The aim of this study was to compare the interventional outcomes between two groups of patients, one treated with endovascular coiling and the other treated with surgical clipping.This prospective study included 48 patients with intracranial aneurysms who underwent endovascular coiling (27 patients or surgical clipping (21 patients from July 2011 to August 2013. 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.

    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.

    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 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.

    International Nuclear Information System (INIS)

    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.

    Objectives. This study aimed to clarify the relationship between community water fluoridation (CWF) and IQ. Methods. We conducted a prospective study of a general population sample of those born in Dunedin, New Zealand, between April 1, 1972, and March 30, 1973 (95.4% retention of cohort after 38 years of prospective follow-up). Residence in a CWF area, use of fluoride dentifrice and intake of 0.5-milligram fluoride tablets were assessed in early life (prior to age 5 years); we assessed IQ repeatedly between ages 7 to 13 years and at age 38 years. Results. No clear differences in IQ because of fluoride exposure were noted. These findings held after adjusting for potential confounding variables, including sex, socioeconomic status, breastfeeding, and birth weight (as well as educational attainment for adult IQ outcomes). Conclusions. These findings do not support the assertion that fluoride in the context of CWF programs is neurotoxic. Associations between very high fluoride exposure and low IQ reported in previous studies may have been affected by confounding, particularly by urban or rural status.

  15. 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.

    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

    Full Text Available Pharyngocutaneous (PC fistula is a common complication following laryngectomy. It leads to increased morbidity, delay in adjuvant treatment, prolonged hospitalization and an increase in treatment costs. Although a number of factors that result in PC fistula have been described, there is still no agreement on the most significant factors. We undertook a prospective study to critically analyze PC fistula and its association with various tumors, patient and treatment related factors. This was a prospective study that included 143 patients who underwent laryngeal surgery for squamous cell carcinoma of the larynx and pyriform sinus. Use of pectoralis major myocutaneous flap to reconstruct the neopharynx, primary disease in pyriform and extensive soft tissue infiltration were significantly associated with PC fistula.

    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

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

    International Nuclear Information System (INIS)

    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)

    A wide variety of occupations has been associated with prostate cancer in previous retrospective studies. Most attention has been paid to farming, metal working, and the rubber industry. Today, these results cannot be affirmed with confidence, because many associations could be influenced by recall bias, have been inconsistent, or have not been confirmed satisfactory in subsequent studies. This study was conducted to investigate and confirm these important associations in a large prospective cohort study. The authors conducted a prospective cohort study among 58,279 men. In September 1986, the cohort members (55-69 years) completed a self-administered questionnaire on potential cancer risk factors, including job history. Related job codes were clustered in professional groups. These predefined clusters were investigated in 3 time windows: 1) profession ever performed, 2) longest profession ever held, and 3) last profession held at baseline. Follow up for incident prostate cancer was established by linkage to cancer registries until December 1993. A case-cohort approach was used based on 830 cases and 1525 subcohort members. To minimize false-positive results, 99% confidence intervals (99% CI) were calculated. Although moderately decreased prostate cancer risks were found for electricians, farmers, firefighters, woodworkers, textile workers, butchers, salesmen, teachers, and clerical workers, none of the relative risks (RR) were found to be statistically significant. For road transporters, metal workers, and managers, no association with prostate cancer risk was found. Although the RR for railway workers, mechanics, welders, chemists, painters, and cooks was moderately increased, these estimates were not statistically significant. For men who reported to have ever worked in the rubber industry, we found a substantially increased prostate cancer risk, but not statistically significant (RR, 4.18; 99% CI = 0.22-80.45). For policemen, we found a substantial and

    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: Surgical correction of congenital talipes equino varus (ctev is to address adequately all aspects of this complex foot deformity. Various exposures have been elucidated with varying results and complications. This prospective study discusses the cincinnati approach advocated by Mackay to address the various aspects of clubfoot correction. Objective: To study the adequacy of exposure, wound healing and problems related to Cincinnati approach. To study the effectiveness of primary surgical correction. METHODS: The present prospective study includes treatment of 24 feet in 21 patients with clubfoot treated with posteromedial and lateral soft tissue release by Cincinnati approach and followed up with an average follow up of 6.9 months. 3 (12.5% were followed up for 1 year and 3 (12.5% lost for the follow up. 18 (75% were followed up to 6 months. All were resistant to correction by conservative method. Age at operation averaged 1.6 year, ranged from 9 months to 3 years. RESULTS: Results were evaluated using Laaveg and Ponseti functional rating system of clubfoot. Postoperatively the average arc of movement in ankle joint was 370, which was 50% of normal limb. Inversion, eversion movement of subtalar joint was 230, bimalleolar angle was 770.The functional results were excellent in 6 feet (25%, good in 12 feet (50%, fair in 5 feet (20.83% and poor in 1 foot (4.17%. In our series complications encountered were post-operative focal necrosis in 3 feet (12.5% and marginal necrosis in 3 feet (12.5%. CONCLUSION: Cincinnati incision provides an adequate exposure for extensive surgical release under direct vision, there by bony realignment of talus over calcaneus was restored and hence the restoration of normal bimalleolar angle. Skin closure is not found to be a problem in achieving a primary closure. Wound healing leaves only a thin and cosmetically acceptable scar.

    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.

    2012-09-01

    Full Text Available Abstract Background Teen mothers face many challenges to successful breastfeeding and are less likely to breastfeed than any other population group in the U.S. Few studies have investigated this population; all prior studies are cross-sectional and collect breastfeeding data retrospectively. The purpose of our qualitative prospective study was to understand the factors that contribute to the breastfeeding decisions and practices of teen mothers. Methods This prospective study took place from January through December 2009 in Greensboro, North Carolina in the U.S. We followed the cohort from pregnancy until two weeks after they ceased all breastfeeding and milk expression. We conducted semi-structured interviews at baseline and follow-up, and tracked infant feeding weekly by phone. We analyzed the data to create individual life and breastfeeding journeys and then identified themes that cut across the individual journeys. Results Four of the five teenagers breastfed at the breast for nine days: in contrast, one teen breastfed exclusively for five months. Milk expression by pumping was associated with significantly longer provision of human milk. Breastfeeding practices and cessation were closely connected with their experiences as new mothers in the context of ongoing multiple roles, complex living situations, youth and dependency, and poor knowledge of the fundamentals of breastfeeding and infant development. Breastfeeding cessation was influenced by inadequate breastfeeding skill, physically unpleasant and painful early experiences they were unprepared to manage, and inadequate health care response to real problems. Conclusions Continued breastfeeding depends on a complex interplay of multiple factors, including having made an informed choice and having the skills, support and experiences needed to sustain the belief that breastfeeding is the best choice for them and their baby given their life situation. Teenagers in the US context need to have

    For tonsillectomy, the ultrasonic harmonic scalpel has been purported to cause less tissue injury and postoperative morbidity while providing adequate levels of hemostasis. We undertook a prospective study to compare outcomes in 162 patients who had undergone harmonic scalpel tonsillectomy and 40 patients who had undergone monopolar diathermy tonsillectomy over a 33-month period. We found that patients in the harmonic scalpel group experienced significantly less intraoperative bleeding (5.0 vs. 16.5 ml; p < 0.0001). There was no clinically significant difference between the groups with respect to (1) the amount of operating time, (2) the incidence of postoperative nausea and vomiting, dysphonia, and primary or secondary bleeding, and (3) the amount of time patients needed to resume normal diet and activities.

We examined and categorized the immediate postoperative complications according to various tumor pathologies. Materials and Methods: We carried out a prospective study in 152 consecutive patients and noted various postoperative complications during neurosurgical intensive care unit stay (within 48 hrs of hospital stay in patients undergoing transsphenoidal removal of pituitary tumors. Results: In our series, various groups showed different postoperative complications out of which, cerebrospinal fluid leak was the commonest followed by diabetes insipidus, postoperative nausea and vomiting, and hematoma at operation site. Conclusion: Various immediate postoperative complications can be anticipated in transsphenoidal pituitary surgery even though, it is considered to be relatively safe.

    BACKGROUND: Incense use is an integral part of daily life in large parts of Asia. The burning of incense is a powerful producer of particulate matter and the smoke contains a multitude of well-characterized carcinogens. However, to the authors' knowledge, no convincing association has been reported...... between exposure to incense smoke and the development of cancer. Therefore, the relation between incense use and the risk of respiratory tract carcinomas was analyzed in a prospective cohort study. METHODS: Between 1993 and 1998, a population-based cohort of 61,320 Singapore Chinese who were free...... with incense use was estimated using a Cox proportional hazards model. RESULTS: A total of 325 upper respiratory tract (UPT) carcinomas and 821 lung carcinomas were observed during follow-up. Incense use was associated with a significantly increased risk of UPT carcinomas other than nasopharyngeal, whereas...

    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 {sup 40}Ca, 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.

    1993-01-01

    A prospective, controlled study of 50 subjects confirmed claims that major depression or mania may cause temporary disorders of attention, memory, visuo-spatial function, and choice reaction time, and cause-independently of medication-the appearance of glabellar tap, positive hand-face test, nuchocephalic reflex, and graphesthesia. On follow-up, all these phenomena either disappeared or markedly improved. Age and age of onset, but not pre-morbid intelligence or history of ECT, seemed to modulate the severity of the cognitive impairment. Presence of delusions predicted poor (but reversible) visuo-spatial function. Cognitive impairment accompanied by reversible soft neurological signs was more marked but patients thus affected surprisingly showed lower depressive scores; this was interpreted as representing a secondary, 'organic' form of affective disorder (i.e. a behavioural phenocopy of depression) characterised by a reduced capacity to experience depressive symptoms and by little improvement at follow-up.

    Full Text Available Immunocompromised individuals infected with Strongyloides stercoralis may develop severe hyperinfection or disseminated disease with high mortality. Patients with hematological malignancies are at risk because of immunodepression produced either by the disease or its treatment. A prospective study was undertaken at the Hospital de Clínicas de Porto Alegre, from July 1994 to July 1995. Seventy-two (HIV negative, had 3 stool samples collected at different days and had not received recent anti-helmintic therapy. Larvae, isolated in a modified Baermann method, were found in 6 patients, with a resultant prevalence of 8.3%. No complicated strongyloidosis was documented. The positive result for S. stercoralis larvae was significantly associated (p < 0.001 with eosinophilia. Knowledge of prevalence figures and incidence of severe disease is important to adequate guidelines for empirical treatment besides the rigorous search for strongyloidosis in patients with hematological malignancies.

    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

    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

    AIM: To study the incidence of ulcerative colitis UC in the prefecture of Trikala, Central Greece.METHODS: A prospective and population basedepidemiological study of UC from 1990 to the end of 1994was conducted. Trikala is a semirural prefecture of Central Greece with a population of 138 946 (census 1991). Three gastroenterologists (one hospital based, two private doctors)of the prefecture participated in this study.RESULTS: During the study period, 66 new histologically verified cases of UC were recorded. The mean annual incidence of the disease in 1990-1994 was 11.2 per 105inhabitants (95%CI: 8.7-14.3). There was no difference between men and women (annual incidence: 10.5 and 12.0 per 105 inhabitants respectively), either among urban,semirural or rural populations (annual incidence: 11.7,17.1 and 9.9 per 105 inhabitants respectively). The majority (56%) of the patients never smoked and a quarter were ex-smokers. About a half of all cases had proctitis.CONCLUSION: UC is common in Central Greece and its incidence is similar to that in North-Western European countries.

  15. 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.

    We prospectively studied early bedside standard EEG characteristics in 61 acute postanoxic coma patients. Five simple EEG features, namely, isoelectric, discontinuous, nonreactive to intense auditory and nociceptive stimuli, dominant delta frequency, and occurrence of paroxysms were classified yes or no. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the receiver operating characteristic curve (AUC) of each of these variables for predicting an unfavorable outcome, defined as death, persistent vegetative state, minimally conscious state, or severe neurological disability, as assessed 1 year after coma onset were computed as well as Synek's score. The outcome was unfavorable in 56 (91.8%) patients. Sensitivity, specificity, PPV, NPV, and AUC of nonreactive EEG for predicting an unfavorable outcome were 84%, 80%, 98%, 31%, and 0.82, respectively; and were all very close to the ones of Synek score>3, which were 82%, 80%, 98%, 29%, and 0.81, respectively. Specificities for predicting an unfavorable outcome were 100% for isoelectric, discontinuous, or dominant delta activity EEG. These 3 last features were constantly associated to unfavorable outcome. Absent EEG reactivity strongly predicted an unfavorable outcome in postanoxic coma, and performed as accurate as a Synek score>3. Analyzing characteristics of some simple EEG features may easily help nonneurophysiologist physicians to investigate prognostic issue of postanoxic coma patient. In this study (a) discontinuous, isoelectric, or delta-dominant EEG were constantly associated with unfavorable outcome and (b) nonreactive EEG performed prognostic as accurate as a Synek score>3.

    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.

  18. Prospective study of nutritional support during pelvic irradiation

    International Nuclear Information System (INIS)

    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

    Collapsing focal segmental glomerulosclerosis (cFSGS) is characterized by rapid progression to end-stage renal disease (ESRD). We evaluated the clinicopathological spectrum of cFSGS and compared its clinical behavior to steroid and tacrolimus (TAC)-resistant noncollapsing focal segmental glomerulosclerosis (FSGS). All patients (>14 years) diagnosed with cFSGS were enrolled in the study. Staining for differentiated podocyte markers such as WT 1, PAX and KI67 were performed in all patients. The outcome and histological features of cFSGS was compared with a prospectively followed cohort of steroid and TAC-resistant noncollapsing FSGS. The study included 22 cFSGS patients and 19 cases of steroid and TAC-resistant FSGS. Complete remission, partial remission, steroid resistance, progression to ESRD and death were observed in 13.6%, 4.5%, 27.3%, 36.4% and 18.2% patients, respectively. Patients with cFSGS had higher serum creatinine and more advanced tubulointerstitial changes compared to resistant FSGS. Twenty-six percent of therapy resistant noncollapsing FSGS progressed to ESRD after two years of stopping TAC. However, there was no difference in progression to ESRD between cFSGS and therapy-resistant noncollapsing FSGS at the end of two years. Glomerular collapse in the setting of FSGS is poorly responsive to treatment and has a high rate of progression to ESRD. The long-term prognosis of cFSGS and steroid and TAC-resistant FSGS are similar.

    Full Text Available Background: Dermatomycoses are more prevalent in India due to favourable climatic conditions, poverty, poor hygiene and overcrowding. Sparse published data are available regarding superficial dermatomycoses from India. Methods: In this prospective study, demographic characteristics, clinical spectrum and risk factors for the development were studied in 198 patients with superficial dermatomycoses. Results: Their mean age was 34.1 ± 15.3 years; there were 108 (54.5% males. Majority of the patients (50.5% belonged to upper-lower socio-economic status (Class IV as per modified Kuppuswamy’s classification. Most of the patients (69.7% had presented with dermatophytoses. Among superficial dermatomy-coses, tinea corporis was the most common (29.3% clinical type. Potassium hydroxide mount was positive in 77.7% and culture was positive in 30.8%. Trichophyton rubrum was the most common species isolated (64%. Multivariable analysis using logistic regression revealed older age (> 50 years to be an independent predictor for the development of tinea corporis (p<0.001. Conclusions: Our observations suggest that superficial dermatomycoses are an important cause of morbidity and should be carefully searched for especially in the elderly so that effective curative treatment can be instituted.

    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.

    Objective: To evaluate the clinical efficacy of polycarboxylate cement as retrograde filling material. Design: A prospective clinical study was made of 25 patients subjected to periapical surgery with ultrasound and magnifying loupes, in which polycarboxylate cement was used as retrograde filling material. Measurements were made of the area and diameter of the lesions pre- and postoperatively, and 6 and 12 months after the operation. The apical resection and retrograde filling areas were also measured, and the prognosis following surgery was recorded. Results: A total of 23 patients with 31 apicoectomized teeth were studied (2 patients being lost to follow-up). The mean area of the periapical lesions before surgery was 52.25 mm2, with a mean major diameter of 6.1 mm and a mean lesser diameter of 4.8 mm. The success rate after 12 months was 54.7%, according to the criteria of Von Arx and Kurt. The prognosis was poorer in females, in larger lesions, and in cases with larger retrograde filling areas. Conclusions: Polycarboxylate cement offers good results, with important bone regeneration after periapical surgery. Key words: Periapical surgery, endodontic treatment, polycarboxylate cement.

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

    International Nuclear Information System (INIS)

    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.

    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.

    Full Text Available Purpose. We evaluated the efficacy of arthrocentesis in the treatment of temporomandibular joint (TMJ disorders. Material and Methods. In this prospective clinical case series, 30 consecutive patients with TMJ disorders underwent arthrocentesis using saline and sodium hyaluronate injections. Outcome measures were TMJ pain, maximum mouth opening (MMO, joint noises, and anatomical changes in the TMJ architecture. Patients were evaluated using cone-beam computed tomography (CBCT and magnetic resonance imaging (MRI at the beginning of treatment and 60 days after the last arthrocentesis. Pretreatment and posttreatment clinical parameters were compared using paired and unpaired t-tests, and McNemar’s test was used to evaluate CBCT and MRI changes (. Results. At 1-year follow-up examinations, visual analogue scale scores indicated that pain was reduced significantly and mean postoperative MMO was increased significantly. CBCT findings showed no significant change, and MRI showed only slight reductions in inflammatory signs. Conclusions. Within the limitations of this study, we can conclude that arthrocentesis is a simple, minimally invasive procedure with a relatively low risk of complications and significant clinical benefits in patients with TMJ disorders. This trial is registered with NCT01903512.

    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

    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

    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.

    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.

    Background Kidney transplantation corrects or improves many complications of chronic kidney disease, but its impact on disordered mineral metabolism is incompletely understood. Methods We performed a multicenter, prospective, observational cohort study of 246 kidney transplant recipients in the United States to investigate the evolution of mineral metabolism from pretransplant through the first year after transplantation. Participants were enrolled into 2 strata defined by their pretransplant levels of parathyroid hormone (PTH), low PTH (>65 to ≤300 pg/mL; n = 112), and high PTH (>300 pg/mL; n = 134) and underwent repeated, longitudinal testing for mineral metabolites. Results The prevalence of posttransplant, persistent hyperparathyroidism (PTH >65 pg/mL) was 89.5%, 86.8%, 83.1%, and 86.2%, at months 3, 6, 9, and 12, respectively, among participants who remained untreated with cinacalcet, vitamin D sterols, or parathyroidectomy. The results did not differ across the low and high PTH strata, and rates of persistent hyperparathyroidism remained higher than 40% when defined using a higher PTH threshold greater than 130 pg/mL. Rates of hypercalcemia peaked at 48% at week 8 in the high PTH stratum and then steadily decreased through month 12. Rates of hypophosphatemia (<2.5 mg/dL) peaked at week 2 and then progressively decreased through month 12. Levels of intact fibroblast growth factor 23 decreased rapidly during the first 3 months after transplantation in both PTH strata and remained less than 40 pg/mL thereafter. Conclusions Persistent hyperparathyroidism is common after kidney transplantation. Further studies should determine if persistent hyperparathyroidism or its treatment influences long-term posttransplantation clinical outcomes. PMID:26177089

    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.

    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

    Full Text Available BACKGROUND: Sepsis is the commonest cause of neonatal mortality .It is responsible for 30 - 50% of neonatal deaths in developing countries. Anemia during pregnancy is highly prev alent in India. Anemia in pregnancy has adverse effects on maternal and fetal health. Obstetrical complications like low birth weight babies, IUGR, increased rate of preterm deliveries & increased perinatal mortality are known. OBJECTIVES: Primary: To find relation between maternal anemia and proven neonatal sepsis. Secondary: To find long term morbidity and mortality of babies born to anemic mother. METHODS: The study was carried out in the Department of Pediatrics and Obstetrics and Gynaecology, Dr. B. R. Ambedkar Medical College and Hospital, Bangalore for a period of two years. A prospective randomized study conducted on 200 pregnant women who were found to be anaemic. All subjects were analyzed in full details and hemoglobin estimation done during 1 st v isit, at 30 th week and 36 th week of gestation. Blood cultures were done in all the babies admitted to NICU for various reasons. RESULTS: The incidence of mild anaemia 29.5%, moderate anemia 53% and 17.5% severe anaemia was noted in mothers. Out of total 20 0, 194 were liveborn and met the inclusion criteria, 20% were preterm, 28% IUGR, 51 babies(25 % required NICU admission due to various reasons out of which 9% developed proven sepsis. CONCLUSION: Anaemia in pregnancy continues to be a major problem in dev eloping countries with maternal and fetal complications and neonatal sepsis was found to be indirectly associated with maternal anaemia.

    Full Text Available Context and Aim: Ventilator-associated pneumonia (VAP remains to be the commonest cause of hospital morbidity and mortality in spite of advances in diagnostic techniques and management. This project aims to study the various risk factors and the common microbial flora associated with VAP. It also evaluates the use of APACHEIII scores for prognostication. Study Design: A prospective cohort study was conducted over 1 year in medical critical care unit (CCU of a tertiary-care teaching hospital. Methods and Material: VAP was diagnosed using the clinical pulmonary infection score (CPIS of more than 6. The study cohort comprised 51 patients. All CCU patients requiring mechanical ventilation for more than 48 h formed the study group. Statistical Analysis Used: Univariate analysis, c2-test, and paired "t-test." Results: Twenty-four out of fifty-one cases developed VAP. These cases had an average APACHEIII score of more than 55 on admission to critical care unit (CCU. They needed prolonged mechanical ventilation and had lower PaO2/FiO2 ratio as compared with the remaining patients who did not develop VAP. Pseudomonas aeroginosa was the commonest and most lethal organism. The mortality in the VAP group was 37% and correlated very well with higher APACHEIII scores on admission. Conclusions: Longer duration of mechanical ventilation and the need of reintubation are associated with proportionate rise in the incidence of VAP. Deteriorating PaO2/FiO2 ratio correlated well with the onset of VAP. Higher APACHEIII scores on admission stratify the mortality risk.

  10. A prospective study of radioimmunoscintigraphy in ovarian cancer

    International Nuclear Information System (INIS)

    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

    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.

    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.

    Once-daily topical brimonidine tartrate (BT) gel 0.5% was shown to be efficacious and safe for the treatment of erythema of rosacea in previous studies including a 4-week treatment phase. In the present 1-year study, we aimed to assess the long-term safety and efficacy of the treatment. Subjects with moderate to severe erythema of rosacea were instructed to apply topical BT gel 0.5% once daily for 12 months. Severity of erythema and adverse events (AEs) were evaluated. Approximately 345 subject years of exposure to BT gel 0.5% was achieved in the study. The incidence of AEs and AEs judged to be related to the study drug was higher at the beginning and decreased over the course of the study. Similar safety profiles were observed between the subjects who had received or not received concomitant therapies for the inflammatory lesions of rosacea. Effect of topical BT gel 0.5% on erythema severity was observed after the first application and the durability of the effect was maintained until the end of the study at month 12, with no tachyphylaxis observed. In conclusion, once-daily topical BT gel 0.5% is safe and consistently effective for the long-term treatment of moderate to severe erythema of rosacea, even in the presence of concomitant therapies for the inflammatory lesions of rosacea.

    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.

    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

    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

  8. Acquisition Study On Cawthorne Channel Prospect For SPDC

    International Nuclear Information System (INIS)

    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

    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.

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

    Directory of Open Access Journals (Sweden)

    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. During admission, aphasia tests were done, notably the ScreeLing Test and the Boston Naming Test. Data were analyzed using Pearson's χ2 test, Fisher's exact test, the Mann-Whitney U test and univariate and multivariate logistic regression analyses. Results: A total of 347 patients were included, of which 115 (33.1% met the criteria for aphasia, with 26 (7.5% meeting the criteria

    Given the increasing numbers of cardiac device implantations worldwide, it is important to determine whether permanent endocardial leads across the tricuspid valve can promote tricuspid regurgitation (TR). Virtually all current data is retrospective, and indicates a signal of TR being increased after permanent lead implantation. However, the precise incidence of moderate or greater TR post-procedure, the exact mechanisms (mechanical, traumatic, functional), and the hemodynamic burden and clinical effects of this putative increase in TR, remain uncertain. We have therefore designed a multicenter, international, prospective study of 300 consecutive patients (recruitment completed, baseline data presented) who will undergo echocardiography and clinical assessment prior to, and at 1-year post device insertion. This prospective study will help determine whether cardiac device-associated TR is real, what are its potential mechanisms, and whether it has an important clinical impact on cardiac device patients.

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.

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

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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

    Background Suspected coronary artery disease (CAD) is one of the most common, potentially life threatening diagnostic problems clinicians encounter. However, no large outcome-based randomized trials have been performed to guide the selection of diagnostic strategies for these patients. Methods The PROMISE study is a prospective, randomized trial comparing the effectiveness of two initial diagnostic strategies in patients with symptoms suspicious for CAD. Patients are randomized to either: 1) functional testing (exercise electrocardiogram, stress nuclear imaging, or stress echocardiogram); or 2) anatomic testing with >=64 slice multidetector coronary computed tomographic angiography. Tests are interpreted locally in real time by subspecialty certified physicians and all subsequent care decisions are made by the clinical care team. Sites are provided results of central core lab quality and completeness assessment. All subjects are followed for ≥1 year. The primary end-point is the time to occurrence of the composite of death, myocardial infarction, major procedural complications (stroke, major bleeding, anaphylaxis and renal failure) or hospitalization for unstable angina. Results Over 10,000 symptomatic subjects were randomized in 3.2 years at 193 US and Canadian cardiology, radiology, primary care, urgent care and anesthesiology sites. Conclusion Multi-specialty community practice enrollment into a large pragmatic trial of diagnostic testing strategies is both feasible and efficient. PROMISE will compare the clinical effectiveness of an initial strategy of functional testing against an initial strategy of anatomic testing in symptomatic patients with suspected CAD. Quality of life, resource use, cost effectiveness and radiation exposure will be assessed. Clinical trials.gov identifier NCT01174550 PMID:24890527

    Background In cardiology,it is controversial whether gender influences prognosis after acute myocardial infarction (MI).We examined the 30-day and 1-year prognosis for female patients with ST-elevation myocardial infarction (STEMI)in Liaoning province,and we analyzed factors that influenced these outcomes.Methods This was a prospective,multicenter,observational study in which patient data were collected by questionnaire at the time of diagnosis and at approximately 30 days and 1 year later by telephone inquiries.Patients were diagnosed with STEMI between June 1,2009 and June 1,2010 at any of the 20 hospitals that gave treatment representative of current STEMI treatment in Liaoning Province.Unified follow-up questionnaire was used to visit the STEMI patients.Results We analyzed data from a total of 1429 consecutive patients with STEMI in Liaoning province.Female patients were older (70.0 vs.60.3,P <0.001) and were less likely to receive emergency reperfusion therapy than male ones (39.2% vs.58.0%,P <0.001).Female gender was associated with higher unadjusted 30-day mortality rates (HR=2.118,95%C/:1.572-2.854,P <0.001) and higher unadjusted 1-year mortality rates (HR=2.174,95%C/:1.659-2.848,P <0.001).Multivariate Cox regression analysis showed that female gender was not an independent predictor of 30-day mortality rates (HR=1.273,95%C/:0.929-1.745,P=0.133) nor of 1-year mortality rates (HR=1.112,95%C/:0.831-1.487,P=0.475).Conclusions Women with STEMI appear to be at increased risk of 30-day and 1-year mortality compared with male STEMI patients,but this difference may be explained by older age and less frequent receipt of reperfusion therapy among the women.

    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.

    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.

    Full Text Available Abstract Background Few prospective cohort studies of distal upper extremity musculoskeletal disorders have been performed. Past studies have provided somewhat conflicting evidence for occupational risk factors and have largely reported data without adjustments for many personal and psychosocial factors. Methods/design A multi-center prospective cohort study was incepted to quantify risk factors for distal upper extremity musculoskeletal disorders and potentially develop improved methods for analyzing jobs. Disorders to analyze included carpal tunnel syndrome, lateral epicondylalgia, medial epicondylalgia, trigger digit, deQuervain’s stenosing tenosynovitis and other tendinoses. Workers have thus far been enrolled from 17 different employment settings in 3 diverse US states and performed widely varying work. At baseline, workers undergo laptop administered questionnaires, structured interviews, two standardized physical examinations and nerve conduction studies to ascertain demographic, medical history, psychosocial factors and current musculoskeletal disorders. All workers’ jobs are individually measured for physical factors and are videotaped. Workers are followed monthly for the development of musculoskeletal disorders. Repeat nerve conduction studies are performed for those with symptoms of tingling and numbness in the prior six months. Changes in jobs necessitate re-measure and re-videotaping of job physical factors. Case definitions have been established. Point prevalence of carpal tunnel syndrome is a combination of paraesthesias in at least two median nerve-served digits plus an abnormal nerve conduction study at baseline. The lifetime cumulative incidence of carpal tunnel syndrome will also include those with a past history of carpal tunnel syndrome. Incident cases will exclude those with either a past history or prevalent cases at baseline. Statistical methods planned include survival analyses and logistic regression. Discussion A

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

    Institute of Scientific and Technical Information of China (English)

    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.

    International Nuclear Information System (INIS)

    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)

    To identify the reasonable criteria in detection of the degree of Fatty liver, we prospectively evaluated sonograms and CT scans in 33 Patients With bright liver on sonography. On sonograms, we analyzed the echogenicity of the liver, acoustic attenuation, and visualization of the portal vein and the diaphragm, Each criterion was scored from 0 to 2. CT criterion for fatty liver was assessed by the attenuation difference between the liver and the spleen on nonocontrast CT scans, The average sonographic grade for CT Grade I was 1.3, Grade II was 2.1,and Grade III was 2.8. The accurate detection rate of each sonographic grade was as follows, Grade

    We measured IgA and IgG antibodies to pertussis toxin (PT) and filamentous hemagglutinin (FHA) in sera from 203 1-year-old children who had received one to three doses of a monocomponent PT toxoid vaccine. Ten children (5%) had IgA antibody to PT indicating recent infection; seven of these children...... had received three doses of vaccine. PT IgA responders did not have significantly longer coughing episodes than PT IgA non-responders. Since an IgA antibody response occurs in only approximately 50% of infected children, the actual infection rate in our cohort is estimated to approximately 10......%. The apparent high Bordetella pertussis infection rate in Danish infants suggests that the monocomponent PT toxoid vaccine used in Denmark has limited efficacy against B. pertussis infection.

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.

    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].

    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.

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

    International Nuclear Information System (INIS)

    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

    We prospectively investigated the epidemiologic characteristics of all lacerations (N = 2834) repaired at the Children's Hospital of Philadelphia (Pa) during 1987 and identified common hazards and possible avenues of intervention. Two-year-old children incurred most injuries; males outnumbered females 2:1. Almost two thirds (61.8%) of all lacerations occurred from May through September, and 62.2% between 3 and 9 PM. Most injuries occurred indoors (47.0%), on the sidewalk or street (22.5%), or in the residential yard (13.0%). Injuries usually occurred during play (42.3%) or daily activity (32.1%); 1247 (44.0%) involved some sort of fall. Vectors most frequently causing injury were broken glass bottles (15.0%), wooden furniture (12.0%), and asphalt or concrete (11.0%). Broken glass bottles also most frequently inflicted injuries resulting in functional impairment (0.2%), hospitalization (0.9%), or both. Complications were seen in 8% of all lacerations. Our data confirm the importance of injury-prevention strategies aimed at reduction of discarded glass objects (ie, recycling legislation), improved furniture design, and improved municipal services (ie, street repair).

  3. AN OVERVIEW OF SINONASAL POLYPOSIS: A PROSPECTIVE STUDY

    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.

    Due to a growing numbers of lateral fragility fractures of the femur and their high social costs the need to work out an effective strategy in order to find a better solution for these patients is warranted. From January 2010 to July 2011, we carried out a prospective randomized clinical study comparing the results of patients with femoral lateral fractures treated by nail and cephalic hydroxyapatite coated screws (study group including 27 patients) compared to the patients with the same fractures treated with nail and head standard screws (control group including 27 patients). We defined the two parts of the femoral neck as ROI 1 (under the head screw) and ROI 2 (above the femoral screw) on the AP view. The bone density of the two areas was calculated using DEXA at T0 (1st day post-surgery), at T1 (40th day post-surgery), at T2 (3 months later), at T3 (1 year later). The clinical-radiography evaluations were based on the Harris Hip Score (HHS), ADL test and x-ray views of the hip. As far as the bone mineral density average of ROI 1 and ROI 2 is concerned, we found a significant statistical increase at T1 and T3 in the study group, while it was not significant in the control group. We could account for this data through the higher mechanical stability of hydroxyapatite coated screws than standard screws. In fact, this material was responsible for improved implant osteointegration. Thanks to a 1 year follow-up we were able to demonstrate the implant utility associated with augmentation and the importance of densitometry exams such as easily repeatable and low cost diagnostics to prevent the onset of complications linked to screw loosening.

    Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of cancer therapy. This study evaluates symptoms of CIPN and CIPN-related pain and its influence on psychological functioning and potential predictors of chronic CIPN and pain. In this large prospective questionnaire study, 174 patients receiving adjuvant oxaliplatin or docetaxel were consecutively included. Patients were asked to complete a questionnaire with validated questions on peripheral neuropathy, pain, anxiety and depression, and quality of life at baseline, after the first cycle, halfway through therapy, and 1 year after baseline. Chronic CIPN symptoms (tingling and/or numbness) in the feet at 1-year follow-up were present in 63.6% of patients without preexisting neuropathy in the oxaliplatin group and in 44.8% in the docetaxel group, whereas pain in hands and feet was found in 31.3% and 35.1%, respectively. Both groups had significantly different pain profiles, and persistent pain in the docetaxel group was found to have effect on psychological function. Cumulative dose predicted oxaliplatin-induced neuropathy (P = 0.004), whereas endocrine therapy predicted peripheral pain in the docetaxel group (P = 0.04). There are important differences in acute neuropathic symptoms and chronic pain profiles in patients after oxaliplatin and docetaxel treatment. It is, however, important to recognize that chronic peripheral pain may be unrelated to neuropathy and can be caused by concomitant treatments. Future studies should focus on characterizing and distinguishing CIPN-related pain from other types of pain to determine the best outcome measures for trials on prevention or relief. PMID:26529271

    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.

    Mild Traumatic Brain Injury (mTBI), or concussion, is a major public health concern. There is controversy in the literature regarding the true incidence of postconcussion syndrome (PCS), with the constellation of physical, cognitive, emotional, and sleep symptoms after mTBI. In the current study, we report on the incidence and evolution of PCS symptoms and patient outcomes after mTBI at 3, 6, and 12 months in a large, prospective cohort of mTBI patients. Participants were identified as part of the prospective, multi-center Transforming Research and Clinical Knowledge in Traumatic Brain Injury Study. The study population was mTBI patients (Glasgow Coma Scale score of 13-15) presenting to the emergency department, including patients with a negative head computed tomography discharged to home without admission to hospital; 375 mTBI subjects were included in the analysis. At both 6 and 12 months after mTBI, 82% (n=250 of 305 and n=163 of 199, respectively) of patients reported at least one PCS symptom. Further, 44.5 and 40.3% of patients had significantly reduced Satisfaction With Life scores at 6 and 12 months, respectively. At 3 months after injury, 33% of the mTBI subjects were functionally impaired (Glasgow Outcome Scale-Extended score ≤6); 22.4% of the mTBI subjects available for follow-up were still below full functional status at 1 year after injury. The term "mild" continues to be a misnomer for this patient population and underscores the critical need for evolving classification strategies for TBI for targeted therapy.

    AIM: To clarify the incidence and nature of postoperative hyperbilirubinemia in patients after modern extracorporeal circulation, to analyze possible perioperative risk factors, and to elucidate the clinical significance of postoperative hyperbilirubinemia associated morality and morbidity.METHODS: Between March 2005 and May 2006, three hundred and eighty six consecutive patients undergoing extracorporeal circulation surgery due to a variety of cardiac lesions were investigated prospectively. The incidence of postoperative hyperbilirubinemia was defined as a serum total bilirubin concentration of more than 51 μmol/L. Several perioperative parameters were compared by logistic regression between hyperbilirubinemia and non-hyperbilirubinemia patients to determine possible risk factors contributing to postoperative hyperbilirubinemia and mortality.RESULTS: Overall incidence of postoperative hyperbilirubinemia was 25.3% (98/386). In patients with postoperative hyperbilirubinemia, 56.2%reached peak total bilirubin concentration on the first postoperative day, 33.5% on the second day, and 10.3%on the seventh day. Eighty percent of the increase of total bilirubin resulted from an increase of both conjugated and unconjugated bilirubin. Development of postoperative hyperbilirubinemia was associated with a higher mortality (P < 0.01), longer duration of mechanical ventilation (P < 0.05) and longer ICU stay time (P < 0.05). Preoperative total bilirubin concentration, preoperative right atrium pressure,numbers of valves replaced and of blood transfusion requirement were identified as important predictors for postoperative hyperbilirubinemia.CONCLUSION: Early postoperative hyperbilirubinemia after modern extracorporeal circulation is mainly caused by an increase in both conjugated and unconjugated bilirubin, and is associated with a high mortality.Important contributing factors are the preoperative total bilirubin concentration, preoperative severity of right atrial

    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

    The purpose of this study was to prospectively investigate associations of habitual drinking of regular tea with bone mineral density and fracture risk. Study participants were a multiethnic postmenopausal cohort (n = 91,465) from the nationwide Women's Health Initiative Observational Study. These women were recruited in the United States and aged 50-79 years at the time of enrollment (1994-1998). The average follow-up time was 4.1 years. Habitual consumption of regular tea was assessed with a structured questionnaire at baseline. Clinical fractures during the follow-up were reported in questionnaires, and hip fractures were further confirmed by reviewing medical records. Bone mineral density measurements were conducted among a subgroup of women (n = 4,979) at three Women's Health Initiative bone mineral density centers using dual-energy x-ray absorptiometry. Multivariate analyses suggested a positive trend of increased total body bone mineral density with tea drinking (p tea drinking and the risk of fractures at the hip and forearm/wrist. In conclusion, the results from this study indicate that the effect of habitual tea drinking on bone density is small and does not significantly alter the risk of fractures among the US postmenopausal population.

    We reviewed 77 potential cadaveric allograft recipients who had undergone prospective HLA-A and B locus and HLA-DR antigen identification. Matching was accomplished, giving first priority to HLA-DR compatibility and relying on HLA-A and B antigen matching only in situations of total HLA-DR incompatibility. Complete HLA-DR identification occurred in 56 per cent of all patients. There were 15 patients (19.5 per cent) who received a 2/2 HLA-DR perfect match, with 86.7 plus or minus 8.8 per cent 1-year actuarial graft survival, and 41 (53 per cent) who received a 1/2 HLA-DR match, with 58.2 plus or minus 7.8 per cent 1-year actual allograft survival. Finally, 21 patients (27 per cent) received a 0/2 HLA-DR match, with 64.9 plus or minus 10.7 per cent actual survival. These results and their mirrored mismatching results showed statistically significant allograft success in only the HLA-DR 2/2 matches. Matching for HLA 2 DR donors proved a statistically significant success over the other HLA-DR allograft matches and the older controversial matching system based on HLA-A and B locus antigens. The restricted gene polymorphism of the HLA-DR systems allows for a relatively high percentage of perfect HLA-DR matches.

    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

    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.

    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.

    Epidemiological data regarding tea and coffee consumption and risk of esophageal cancer (EC) is still inconclusive. We examined the association of tea and coffee consumption with EC risk among 442,143 men and women without cancer at baseline from 9 countries of the European Prospective Investigation into Cancer and Nutrition. Tea and coffee intakes were recorded using country-specific validated dietary questionnaires. Cox regression models were used to analyze the relationships between tea and coffee intake and EC risk. During a mean follow-up of 11.1 years, 339 participants developed EC, of which 142 were esophageal adenocarcinoma (EAC) and 174 were esophageal squamous cell carcinoma (ESCC). In the multivariable models, no significant associations between tea (mostly black tea), and coffee intake and risk of EC, EAC and ESCC were observed. In stratified analyses, among men coffee consumption was inversely related to ESCC (HR for comparison of extreme tertiles 0.42, 95% CI 0.20-0.88; p-trend=0.022), but not among women. In current smokers, a significant and inverse association was observed between ESCC risk and tea (HR 0.46, 95% CI 0.23-0.93; p-trend=0.053) and coffee consumption (HR 0.37, 95% CI 0.19-0.73; p-trend=0.011). However, no statistically significant findings were observed using the continuous variable (per 100 mL/d). These data did not show a significant association between tea and coffee consumption and EC, EAC and ESCC, although a decreased risk of ESCC among men and current smokers is suggested, but need to be confirmed in further prospective studies including more cases.

    Full Text Available Abstract Background In order to assess the short term risks of pneumonectomy for lung cancer in contemporary practice a one year prospective observational study of pneumonectomy outcome was made. Current UK practice for pneumonectomy was observed to note patient and treatment factors associated with major complications. Methods A multicentre, prospective, observational cohort study was performed. All 35 UK thoracic surgical centres were invited to submit data to the study. All adult patients undergoing pneumonectomy for lung cancer between 1 January and 31 December 2005 were included. Patients undergoing pleuropneumonectomy, extended pneumonectomy, completion pneumonectomy following previous lobectomy and pneumonectomy for benign disease, were excluded from the study. The main outcome measure was suffering a major complication. Major complications were defined as: death within 30 days of surgery; treated cardiac arrhythmia or hypotension; unplanned intensive care admission; further surgery or inotrope usage. Results 312 pneumonectomies from 28 participating centres were entered. The major complication incidence was: 30-day mortality 5.4%; treated cardiac arrhythmia 19.9%; unplanned intensive care unit admission 9.3%; further surgery 4.8%; inotrope usage 3.5%. Age, American Society of Anesthesiologists physical status ≥ P3, pre-operative diffusing capacity for carbon monoxide (DLCO and epidural analgesia were collectively the strongest risk factors for major complications. Major complications prolonged median hospital stay by 2 days. Conclusion The 30 day mortality rate was less than 8%, in agreement with the British Thoracic Society guidelines. Pneumonectomy was associated with a high rate of major complications. Age, ASA physical status, DLCO and epidural analgesia appeared collectively most associated with major complications.

    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.

    Full Text Available In XANTUS study the safety and efficacy of factor Xa inhibitor rivaroxaban were evaluated in routine clinical practice in patients with non-valvular atrial fibrillation. In consecutive patients who started treatment with rivaroxaban, all adverse events were recorded every 3 months for 1 year. Conclusions of major bleeding, symptomatic thromboembolic complications (stroke, systemic embolism, transient ischemic attack, and myocardial infarction and death from all causes were centrally adjudicated. In total 6784 patients were treated with rivaroxaban at 311 centers in Europe, Israel, and Canada, on average, 329 days. The mean CHADS2 and CHA2DS2-VASc scores were 2.0 and 3.4, respectively. Treatmentemergent major bleeding occurred in 128 patients (2.1 events per 100 patient-years, 118 (1.9 events per 100 patient-years died, and 43 (0.7 events per 100 patient-years suffered a stroke. XANTUS is the first international, prospective, observational study to describe the use of rivaroxaban in a broad non-valvular atrial fibrillation patient population. Rates of stroke and major bleeding were low in patients receiving rivaroxaban in routine clinical practice.

    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.

  14. A Bayesian hierarchical approach for combining case-control and prospective studies.

    Science.gov (United States)

    Müller, P; Parmigiani, G; Schildkraut, J; Tardella, L

    1999-09-01

    Motivated by the absolute risk predictions required in medical decision making and patient counseling, we propose an approach for the combined analysis of case-control and prospective studies of disease risk factors. The approach is hierarchical to account for parameter heterogeneity among studies and among sampling units of the same study. It is based on modeling the retrospective distribution of the covariates given the disease outcome, a strategy that greatly simplifies both the combination of prospective and retrospective studies and the computation of Bayesian predictions in the hierarchical case-control context. Retrospective modeling differentiates our approach from most current strategies for inference on risk factors, which are based on the assumption of a specific prospective model. To ensure modeling flexibility, we propose using a mixture model for the retrospective distributions of the covariates. This leads to a general nonlinear regression family for the implied prospective likelihood. After introducing and motivating our proposal, we present simple results that highlight its relationship with existing approaches, develop Markov chain Monte Carlo methods for inference and prediction, and present an illustration using ovarian cancer data.

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

    Directory of Open Access Journals (Sweden)

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

The advent of molecular biology has advanced and accelerated the study of evolution by allowing direct examination of the genetic material that ultimately determines the phenotypes upon which selection acts. The study of evolution has been furthered through examination of microbial evolution, with large population numbers, short generation times and easily extractable DNA. Such work has spawned the study of microbial biogeography, with the realization that concepts developed in population genetics may be applicable to microbial genomes (Manhes et al. 2011, Martiny et al. 2006.

    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

    In young children, iron deficiency (ID)-the most common cause of anemia-may adversely affect long-term neurodevelopment and behavior. We prospectively evaluated the prevalence of ID and iron deficiency anemia (IDA) in 256 healthy 18- to 36-month-old children in Northern Israel. Complete blood count and ferritin evaluation were performed, and risk factors were assessed. Hemoglobin (Hgb) was compared with first-year routine screening. Complete data were obtained from 208 children: 56.2% were boys; the mean age was 26.1±5.27 months. A prevalence of 5.8% IDA, 16.3% ID without anemia, 9.6% anemia with normal ferritin, and 68.3% normal Hgb and ferritin was found. In nonanemic infants at 1 year of age (n=156), ID/IDA was found in 19.9%, and 12.8% became anemic at study evaluation. Despite iron supplementation in the first year, and normal Hgb at first-year screening, ID and IDA were still prevalent, and might develop during the second year of life.

    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. Before evaluating a patient by CT imaging, i nformed consent was obtained from the patient or guardian. The patient were informed about the radiation exposure in the examination.

    2015-01-01

    The increasing interest in the study of the antioxidant activity of different objects is caused by an unbalance between the formation of reactive oxygen species (ROS) and the performance of the antioxidant system in humans under certain conditions, which leads to oxidative stress and pathological states of the organism. This article presents a brief critical review of the methods that are used to measure integrated antioxidant activity (AOA). It is shown that the most promising methods for measuring AOA are electrochemical ones, particularly potentiometry, as it best fits the nature of the processes causing oxidative stress. The article gives the theoretical rational for requirements that an oxidizer of antioxidants (AO) should meet. The work presents the thermodynamic grounds for the use of an earlier proposed mediator system, kinetics of chemical reactions between AO and the mediator system. In order to confirm reliability and accuracy of the results, numerous correlation studies were conducted, aiming to compare the data obtained with the use the proposed method and independent analytical methods. The article presents the results of the potentiometric study of AOA for a variety of objects, including individual antioxidant → nutritional supplements → food → blood and blood fractions.

    2008-01-01

    Chronological information about Martian processes comes from two sources: Crater-frequency studies and laboratory studies of Martian meteorites. Each has limitations that could be overcome by studies of returned Martian rocks and soils. Chronology of Martian volcanism: The currently accepted chronology of Martian volcanic surfaces relies on crater counts for different Martian stratigraphic units [1]. However, there is a large inherent uncertainty for intermediate ages near 2 Ga ago. The effect of differing preferences for Martian cratering chronologies [1] is shown in Fig. 1. Stoeffler and Ryder [2] summarized lunar chronology, upon which Martian cratering chronology is based. Fig. 2 shows a curve fit to their data, and compares to it a corresponding lunar curve from [3]. The radiometric ages of some lunar and Martian meteorites as well as the crater-count delimiters for Martian epochs [4] also are shown for comparison to the craterfrequency curves. Scaling the Stoeffler-Ryder curve by a Mars/Moon factor of 1.55 [5] places Martian shergottite ages into the Early Amazonian to late Hesperian epochs, whereas using the lunar curve of [3] and a Mars/Moon factor 1 consigns the shergottites to the Middle-to-Late Amazonian, a less probable result. The problem is worsened if a continually decreasing cratering rate since 3 Ga ago is accepted [6]. We prefer the adjusted St ffler-Ryder curve because it gives better agreement with the meteorite ages (Fig.

    Full Text Available Percutaneous nephrolithotomy (PCNL was introduced in 1976, and rapidly evolved into the gold standard for treatment of large and complex renal stones. The procedure continues to evolve with an emphasis on maintaining a high success rate of stone treatment while improving patient outcome with decreased morbidity. With the improvement of instrumentation and experience of PCNL, several modifications to the procedure have taken place in order to reduce the morbidity & early return to normal lifestyle. First described by Wickham et al., another technical variation of tubeless PCNL is totally tubeless approach. The aim of this study is to compare standard and totally tubeless PCNL with respect to safety and efficacy. MATERIALS AND METHODS This study was performed in the Department of Urology, RajaRajeswari Medical College and Hospital, Bangalore from June 2015 to March 2016 after ethics committee clearance. Forty patients planned for PCNL and who gave informed written consent were included in the study. Patients were divided into two groups, standard PCNL (with a nephrostomy tube and totally tubeless PCNL (no ureter stents or ureteric catheters. RESULTS Both the groups were similar in terms of patient and stone characteristics. The mean operation time was slightly longer in the standard group (106.74 minutes than in the totally tubeless group (100.32 minutes, but there was no statistically significant difference. There was no significant difference between the two groups with regard to serum creatinine change or blood loss. However, hospital stay and analgesia requirement was significantly less in the totally tubeless group. CONCLUSION Totally tubeless PCNL leads to shorter hospital stays and less postoperative pain. It can be used with a favourable outcome in selected patients (stone burden <2 cm, single tract access, no significant residual stones, minimal bleeding, and no requirement for a secondary procedure.

    Full Text Available EDITORIAL COMMENT Overactive bladder (OAB is a highly prevalent disorder in the pediatric population. This event negatively affects and impairs children’s development. Antimuscarinics are the mainstay pharmacological management of OAB, but their side effects profile limits their use. Mirabegron, a new molecule with a distinct mechanism of action (b3-adrenoreceptor agonist, was recently approved as monotherapy for idiopathic OAB in adults but has not been studied in the pediatric population. Blais et al. have evaluated the efficacy and safety of mirabegron in the treatment of urinary incontinence in children with idiopathic OAB who were refractory to and/or intolerant of antimuscarinics. This prospective off-label study, using an adjusted-dose regimen of mirabegron (25-50 mg, included pediatric patients with refractory urinary incontinence due to OAB. Patients without symptom improvement or with partial response under intensive behavioral protocol and medical therapy (at least two different antimuscarinic agents were included in the study. Their primary outcome was better reported efficacy than with the use of prior anticholinergic medication. Secondary end points were tolerability and safety. Families were questioned for continence, side effects, compliance, and Patient Perception of Bladder Condition (PPBC questionnaire. A total of 58 patients (14 girls, 44 boys were enrolled in a mirabegron open-label trial. The median age at initiation of mirabegron was 10.1 years [interquartile range (IQR: 8.8-13.5]. The median duration of treatment was 11.5 months (IQR: 6.0-15.0. The median bladder capacity improved from 150 ml to 200 ml (p<0.001. Continence improved in 52 of 58, with 13 being completely dry. The median PPBC score improved from 4.0 to 2.0 (p<0.001. The authors also assessed the safety of mirabegron. All electrocardiogram and blood tests remained normal.

    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

  5. Prospects for Pulsar Studies with the GLAST Large Area Telescope

    Science.gov (United States)

    Harding, Alice K.

    2007-01-01

    The Large Area Telescope (LAT) on the Gamma-ray Large Area Space Telescope (GLAST), due to launch in November 2007, will have unprecedented sensitivity and energy resolution for gamma-rays in the range of 30 MeV to 200 GeV. GLAST is therefore expected to provide major advances in the understanding of high-energy emission from rotation-powered pulsars. As the only presently known galactic GeV source class; pulsars will be one of the most important sources for study with GLAST. The main science goals of the LAT for pulsar studies include an increase in the number of detected radio-loud and radio-quiet gamma-ray pulsars, including millisecond pulsars, giving much better statistics for elucidating population characteristics, measurement of the high-energy spectrum and the shape of spectral cutoffs and determining pulse profiles for a variety of pulsars of different age. Further, measurement of phase-resolved spectra and energy dependent pulse profiles of the brighter pulsars should allow detailed tests of magnetospheric particle acceleration and radiation mechanisms, by comparing data with theoretical models that have been developed. Additionally, the LAT will have the sensitivity to allow blind pulsation searches of nearly all unidentified EGRET sources, to possibly uncover more radio-quiet Geminga-like pulsars.

    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

    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

    Full Text Available PURPOSE: The incidence of retinal detachment in Blacks is generally considered to be low though there are few supporting studies in Africa. This study, thus, aimed at describing the clinical profile of patients with retinal detachment in Southwest Ethiopia. METHODS: A hospital-based study was done on all consecutive retinal detachment patients who presented to Jimma University Hospital over six months period. A semi-structured questionnaire was used to collect patients' sociodemographic characteristics and clinical history. Comprehensive anterior and posterior segment eye examinations were done and risk factors were sought for. Statistical tests were considered significant if P < 0.05. RESULTS: A total of 94 eyes of 80 patients (1.5% had retinal detachment (RD and about 69% of patients were symptomatic for over a month before presentation. The mean age was 41.4 years (SD ±16.5. Fourteen patients (17.5% had bilateral RD. At presentation, 61 eyes (64.9% were blind from RD and 11 (13.8% patients were bilaterally blind from RD. Rhegmatogenous RD was seen in 55 eyes (58.5% and tractional RD in 22 eyes (23.4%. The most common risk factors were ocular trauma (32 eyes, 34.0%, myopia (23 eyes, 24.5%, posterior uveitis (13 eyes, 13.8% and diabetic retinopathy (9 eyes, 9.6%. Most retinal breaks (25 eyes, 43.1% were superotemporal and horse-shoe tear was the most common (19 eyes, 20.2%. Macula was off in 77 eyes (81.9% and 38 eyes (69.1% of RRD eyes had grade C proliferative vitreoretinopathy (PVR. Macular status was significantly associated with PVR (P=0.011, and duration of symptoms (RR=1.25, 95%CI: 1.059-1.475, P=0.040. CONCLUSIONS: A significant numbers of patients with ocular problem had retinal detachment, and nearly two third of the patients presented late. Trauma and myopia were the most important risk factors. People should be educated to improve their health seeking behavior and use eye safety precautions to prevent ocular trauma.

    Employing the stress and coping theory of Lazarus and Folkman, this study followed 117 women age 40 or over regarding personality, cognitive appraisal, coping, and mood variables before breast biopsy, after diagnosis, and, for those who had cancer, after surgery. Upon biopsy, 36 received a cancer diagnosis, and 81 received a benign diagnosis. The 2 groups did not differ on appraisals, coping, or affect before diagnosis. With prebiopsy affect controlled, cancer patients reported more negative affect postbiopsy than did benign patients. Postsurgery, cancer patients expressed less vigor and more fatigue than benign patients, but the groups did not differ on other negative emotions. Prebiopsy, psychosocial predictors accounted for 54% and 29% of the variance in negative and positive emotion, respectively. Prebiopsy variables also predicted postbiopsy and postsurgery mood; cognitive avoidance coping was a particularly important predictor of high distress and low vigor.

    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

    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.

    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.

    Lobna Gaayeb

    Full Text Available BACKGROUND: Pertussis, also known as whooping cough, is a vaccine-preventable respiratory disease caused by Bordetella pertussis infection, against which Senegalese children are immunized with the diphtheria-tetanus-whole cell pertussis vaccine (DTwP. Seroepidemiology of pertussis has been widely described in industrialized countries, but rare are the studies referring to it in developing countries. METHODS: We conducted a longitudinal survey in Northern Senegal to investigate the epidemiology of B. pertussis by evaluating the IgG antibody (Ab response against pertussis toxin (PT. A cohort of 410 children aged 1 to 9 from five villages in the Middle Senegal River Valley were followed-up for 18 months. During that period, five visits were made to assess the immunological status of the children. PRINCIPAL FINDINGS: PT-specific IgG responses were significantly different according to age. Until the age of 3, there was a decrease in the Ab response, which then increased in the older groups. Assessment of IgG antibodies to PT (IgG-PT suggested evidence of recent exposures to the pathogen. Surprisingly, in one of the five villages the average Ab response to PT was very low at all ages during the first 6 months of the study. At the third visit, IgG-PT concentrations peaked to very high levels, to slightly decline at the end of the survey. This indicates an outbreak of B. pertussis, whereas in the other villages a pertussis endemic profile could be observed. CONCLUSIONS: Pertussis is endemic in Northern Senegal despite the introduction of vaccination. The circulation of the bacteria seems to differ between geographic locations and over time. A more complete understanding of the epidemiology of pertussis and its environmental determinants could provide information to adapt vaccination programs.

    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

    Full Text Available Aim: Treating gingival recessions (GRs is a challenge for the practitioner who must take into consideration objective clinical factors, subjective symptoms and also factors related to the patient’s expectations. The aim of this study was to evaluate the postoperative complications associated with connective tissue graft (CTG plus coronally advanced flap (CAF and free gingival graft (FGG used to cover GRs and to compare post-operative morbidities for the two groups of procedures. Material and Methods: A total of 17 patients diagnosed with Miller class 1 to 3 GRs ≥2mm were surgically treated using CTG plus CAF or FGG. When minimum 2 mm of keratinized gingiva was present apically to GR, CTG plus CAF was used. FGG was chosen to cover GRs when keratinized gingiva was absent. Post-operative complications were evaluated with a questionnaire with six questions given to the patients at 14 days follow-up visit. The study used a 1 to 10 visual analogic scale (VAS and the levels of outcomes were classified as “none to minimum” “moderate” and “very important/severe”. Results: A total of 21 procedures, 10 CTG plus CAG and 11 FGG were included in the analysis. No palatal bleeding and no severe pain or swelling were recorded. The patients experienced more pain in the grafted area than in the donor area, for both surgical techniques, with a mean value of 3.09 (1.3 standard deviation sd versus 2.27 (1.4 sd for CTG plus CAF group and of 3.7 (2.21 sd versus 2.9 (1.7 sd for FGG group, respectively. CTG plus CAF generated significantly higher scores of tumefaction than FGG, the mean values being 2.45 (0.93 sd and 4 (2.21 sd (t-value=2.12, p<0.05 respectively. Conclusion: The complications associated with the two periodontal surgical approaches seem manageable and clinically acceptable.

    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.

    Objective: To analyze the preliminary experience of radiosurgery for Vestibular Schwannomas at the Pontificia Universidad Catolica de Chile. Material and methods: The first 17 patients with sporadic Vestibular Schwannomas treated by radiosurgery at our institution are reported. The marginal dose used was 12 to 12.5 Gy. prescribed at the 70 or 80 isodose fine. Patients were controlled at 6, 12 and 24 months with magnetic resonance, audiometric study and clinical examination. Results: In all of the 17 patients treated a decrease tumor enhancement on MR was demonstrated. In 16 patients (94%) a pattern of central tumor necrosis was observed during the firs year Actuarial useful hearing was maintained in 62.5% at 2 year after treatment. Facial nerve function was maintained in all of the 15 patients with normal function at treatment (100%). Trigeminal function was maintained in ah of the 14 patients (100%) with previous normal trigeminal function. The mean time to return to work or normal activities was 11.5 days after treatment. Conclusions: These preliminary results are comparable with results published in the literature and reinforce the demonstrate role of radiosurgery in the management of vestibular schwannomas

    Full Text Available In the variegated landscape of languages and cultures of Borneo, the study of languages is a powerful tool to shed light on the intricate history of relations that has long been obscured by the polarization between ‘Dayak’ and ‘Malay’. This article looks at some of the features of Lebu’ Kulit Kenyah, Penan Benalui, Punan Tubu’ and Ma’ Pnaan (Punan Malinau/Segah languages to clarify the linguistic and cultural affiliations among groups that were otherwise lumped together in vague classifications. It demonstrates what is to follow: according to a number of phonological, morphological and lexical evidence, and other historical evidence, Lebu’ Kulit has to be listed among the Kayanic languages. Penan Benalui, like the other Penan languages, is not a Kenyah language, whereas Punan Tubu’, despite the alleged cultural and social similarity with other Punan groups, cannot be classified within the Penan branch nor with other Punan languages. Ma’ Pnaan or Punan Malinau/Segah is not a Punan language and is linguistically classified within the Kayanic branch of the Kayan-Kenyah subgroup.

    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 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.

    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.

    AIM: There is limited information on the natural history of HCV infection in China. We investigated the outcome of HCV infection after nine-year follow-up and the risk factors in blood donors in China in order to provide the foundation for prevention and therapy.METHODS: A total of 172 cases of HCV infection with antiHCV positive and ALT abnormality were enrolled in the archives when was screened blood in Hebei Province in 1993. In them 142 blood donors were followed up till July 2002. No antiviral treatment was applied to them during the period of infection. In the present study, anti-HCV, HCVRNA and aminotransferase were detected and genotyping was conducted by the method of restriction fragment length polymorphism(RFLP). B-type ultrasound detection was performed in all the patients. Age, sex, alcohol consumption and clinical symptoms were questioned.RESULTS: After nine years' follow-up, 10.56% (15/142)of the cases were negative for anti-HCV and 16.42% (12/134)of them were negative for HCV-RNA. The genotypes 1b,2a and 1b/2a were 91.07%, 6.25% and 2.68% respectively.Twelve cases (8.45%) were negative for both HCV RNA and anti-HCV. The rate of chronicity in this group was 83.58% (112/134), and the rate of viral spontaneous resolution was 16.42% (22/134). The mean level of ALT,AST, γ-GT in HCV RNA positive cases was significantly higher than that in HCV RNA negative cases (P<0.001).The abnormal rate of ALT and/or AST in male donors was significantly higher than that in female donors (P = 0.005).The rate of progression to liver cirrhosis from chronic hepatitis C was significantly higher in the cases of super-infection with HBV than that in the cases of single HCV infection.Overdose alcohol consumption promoted the progression to chronicity.CONCLUSION: This area (Hebei Province) has a higher rate of chronicity in HCV infection, and measures should be taken to prevent its progression to serious liver diseases,especially for patients super-infected with HCV and HBV.
