    The aim of this study was to conduct a re-evaluation of current strategies for peri-operative prophylaxis of infections in orthopaedic surgery of geriatric patients (≥65 years) with proximal femoral fractures (PFF). Between 01/2010 and 08/2014 all post-operative infections after stabilization of PFF of 1,089 geriatric patients were recorded retrospectively. All patients pre-operatively received a single dose of 1.5 g cefuroxime (group 1). These were compared to prospectively determined post-operative rates of surgical site infection (SSI) of 441 geriatric patients, which were operated on between 09/2014 and 03/2017 due to PFF. In this second group we investigated the urinary tract on admission. Bacteriuria was treated with the pre-operative single dose of 1.5 g cefuroxime along with ciprofloxacin for five days, beginning on admission. Level of significance was set to p infection. Multi-resistant pathogens were found in 15 patients and pathogens were cefuroxime-resistant in 37. The differences of SSI after at least three months were 2.1% in group 1 and 0.45% in group 2 for all patients with surgery of PFF (p < 0.02) and for those with arthroplasty (p < 0.037) significant. The immediate antibiotic therapy of a prevalent bacteriuria for five days decreases the risk of SSI after surgery of PFF. Our single-centre study can only point out the problem of prevalent reservoirs of pathogens and the need for treatment. Evidence-based therapy concepts (indications of antibiotics, classes, duration) have to be developed in multi-centric and prospective studies.

    The aim of this study was to compare the morbidity and short-term efficacy of retro-pubic (TVT) and inside-out trans-obturator (TVT-O) sub-urethral sling in the treatment of stress urinary incontinence. This was a prospective multi-centre randomised trial; 231 women with primary stress urinary incontinence were randomised to TVT (114) or TVT-O (117). The International Consultation on Incontinence-Short Form (ICIQ-SF), Women Irritative Prostate Symptoms Score (W-IPSS) and Patient Global Impression of Severity (PGI-S) questionnaires were used to evaluate the impact of incontinence and voiding dysfunction on QoL and to measure the patient's perception of incontinence severity. The primary and secondary outcome measures were rates of success and complications. The SPSS software was used for data analysis. The TVT-O procedure was associated with significantly shorter operation time and with a more extensive use of general anaesthesia when compared with TVT. There were 5 (4%) bladder perforations in the TVT group compared with none in the TVT-O group. Rates of early post-operative urinary retention and voiding difficulty were similar for both groups and no difference was found in the average hospital stay. Six patients (5%) in the TVT-O group complained of thigh pain in the post-operative course. The median follow-up time was 6 months. Two hundred eighteen patients were available for the analysis of outcomes. Subjective and objective cure rates were 92% and 92% in the TVT group and 87% and 89% in the TVT-O group. The ICIQ-SF questionnaire symptoms score showed a highly statistical decrease in both groups, the W-IPSS on the contrary was unchanged. Our data show that both procedures were equally effective in the short-term for the treatment of stress urinary incontinence with a highly significant improvement in incontinence-related QoL.

    To investigate whether neonatal hyperglycaemia in the first postnatal week is associated with treatment-demanding retinopathy of prematurity (ROP). This is a Danish national, retrospective, case-control study of premature infants (birth period 2003-2006). Three national registers were searched, and data were linked through a unique civil registration number. The study sample consisted of 106 cases each matched with two comparison infants. Matching criteria were gestational age (GA) at birth, ROP not registered and born at the same neonatal intensive care unit. Potential 'new' risk factors were analysed in a multivariate logistic regression model, while adjusted for previously recognised risk factors (ie, GA at birth, small for gestational age, multiple birth and male sex). Hospital records of 310 preterm infants (106 treated; 204 comparison infants) were available. Nutrition in terms of energy (kcal/kg/week) and protein (g/kg/week) given to the preterm infants during the first postnatal week were statistically insignificant between the study groups (Mann-Whitney U test; p=0.165/p=0.163). Early postnatal weight gain between the two study groups was borderline significant (t-test; p=0.047). Hyperglycaemic events (indexed value) were statistically significantly different between the two study groups (Mann-Whitney U test; p<0.001). Hyperglycaemia was a statistically independent risk factor (OR: 1.022; 95% CI 1.002 to 1.042; p=0.031). An independent association was found between the occurrence of hyperglycaemic events during the first postnatal week and later development of treatment-demanding ROP, when adjusted for known risk factors. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    The overall benefits of craniectomy must include procedural risks from cranioplasty. Cranioplasty carries a high risk of surgical site infections (SSI) particularly with antibiotic resistant bacteria. The goal of this study was to measure the effect of a cranioplasty bundle on peri-operative complications. The authors queried a prospective, inpatient neurosurgery database at Kaiser Sacramento Medical Center for craniectomy and cranioplasty over a 7 year period. 57 patients who underwent cranioplasties were identified. A retrospective chart review was completed for complications, including surgical complications such as SSI, wound dehiscence, and re-do cranioplasty. We measured cranioplasty complication rates before and after implementation of a peri-operative bundle, which consisted of peri-operative vancomycin (4 doses), a barrier dressing through post-operative day (POD) 3, and de-colonization of the surgical incision using topical chlorhexidine from POD 4 to 7. The rate of MRSA colonization in cranioplasty patients is three times higher than the average seen on ICU admission screening (19% vs. 6%). The cranioplasty surgical complication rate was 22.8% and SSI rate was 10.5%. The concurrent SSI rate for craniectomy was 1.9%. Organisms isolated were methicillin-resistant Staphylococcus aureus (4), methicillin-sensitive S. aureus (1), Propionibacterium acnes (1), and Escherichia coli (1). Factors associated with SSI were peri-operative vancomycin (68.6% vs. 16.7%, p=0.0217). Complication rates without (n=21) and with (n=36) the bundle were: SSI (23.8% vs. 2.8%, p=0.0217) and redo cranioplasty (19% vs. 0%, p=0.0152). Bundle use did not affect rates for superficial wound dehiscence, seizures, or hydrocephalus. The cranioplasty bundle was associated with reduced SSI rates and the need for re-do cranioplasties.

    2009-07-08

    Surgical site infections (SSIs) are associated with significant morbidity, mortality, and resource utilization and are potentially preventable. Peri-operative hyperglycaemia has been associated with increased SSIs and previous recommendations have been to treat glucose levels above 200 mg/dL. However, recent studies have questioned the optimal glycaemic control regimen to prevent SSIs. Whether the benefits of strict or intensive glycaemic control with insulin infusion as compared to conventional management outweigh the risks remains controversial. To summarise the evidence for the impact of glycaemic control in the peri-operative period on the incidence of surgical site infections, hypoglycaemia, level of glycaemic control, all-cause and infection-related mortality, and hospital length of stay and to investigate for differences of effect between different levels of glycaemic control. A search strategy was developed to search the following databases: Cochrane Wounds Group Specialised Register (searched 25 March 2009), The Cochrane Central Register of Controlled Trials, The Cochrane Library 2009, Issue 1; Ovid MEDLINE (1950 to March Week 2 2009); Ovid EMBASE (1980 to 2009 Week 12) and EBSCO CINAHL (1982 to March Week 3 2009). The search was not limited by language or publication status. Randomised controlled trials (RCTs) were eligible for inclusion if they evaluated two (or more) glycaemic control regimens in the peri-operative period (within one week pre-, intra-, and/or post-operative) and reported surgical site infections as an outcome. The standard method for conducting a systematic review in accordance with the Cochrane Wounds Group was used. Two review authors independently reviewed the results from the database searches and identified relevant studies. Two review authors extracted study data and outcomes from each study and reviewed each study for methodological quality. Any disagreement was resolved by discussion or by referral to a third review author. Five

  15. Current Thinking In Pediatric Peri-operative Fluid Therapy

    Full Text Available Proper perioperative fluid management is critical to maintain cardiovascular stability and adequate tissue perfusion. The volume and composition of fluid should be adapting to the physiology of the child and compensating for the peri-operative events. Traditionally physicians were calculating pediatric maintenance fluid requirements based on studies conducted on healthy children more than 50 years ago by Holliday and Segar. But a search of literature failed to reveal a relevant prospective study critically evaluating the content and volume of Holliday and Segar prescription. But off late there has been a major debate and re-evaluation about this concept because of serious concerns regarding development of hyponatremia and hyperglycemia. This can result in serious neurological damage or even death in a sick child. This brief review is an attempt to explain how the original concept was formed and what is the current thinking?

    Full Text Available Purpose : To evaluate peri-operative multicatheter interstitial pulsed-dose-rate brachytherapy (PDR-BT with an intra-operative catheter placement to boost the tumor excision site in breast cancer patients treated conservatively. Material and methods: Between May 2002 and October 2008, 96 consecutive T1-3N0-2M0 breast cancer patients underwent breast-conserving therapy (BCT including peri-operative PDR-BT boost, followed by whole breast external beam radiotherapy (WBRT. The BT dose of 15 Gy (1 Gy/pulse/h was given on the following day after surgery. Results: No increased bleeding or delayed wound healing related to the implants were observed. The only side effects included one case of temporary peri-operative breast infection and 3 cases of fat necrosis, both early and late. In 11 patients (11.4%, subsequent WBRT was omitted owing to the final pathology findings. These included eight patients who underwent mastectomy due to multiple adverse prognostic pathological features, one case of lobular carcinoma in situ, and two cases with no malignant tumor. With a median follow-up of 12 years (range: 7-14 years, among 85 patients who completed BCT, there was one ipsilateral breast tumor and one locoregional nodal recurrence. Six patients developed distant metastases and one was diagnosed with angiosarcoma within irradiated breast. The actuarial 5- and 10-year disease free survival was 90% (95% CI: 84-96% and 87% (95% CI: 80-94%, respectively, for the patients with invasive breast cancer, and 91% (95% CI: 84-97% and 89% (95% CI: 82-96%, respectively, for patients who completed BCT. Good cosmetic outcome by self-assessment was achieved in 58 out of 64 (91% evaluable patients. Conclusions : Peri-operative PDR-BT boost with intra-operative tube placement followed by EBRT is feasible and devoid of considerable toxicity, and provides excellent long-term local control. However, this strategy necessitates careful patient selection and histological confirmation

  20. Rebound hyperglycaemia in diabetic cats.

    2016-08-01

    Rebound hyperglycaemia (also termed Somogyi effect) is defined as hyperglycaemia caused by the release of counter-regulatory hormones in response to insulin-induced hypoglycaemia, and is widely believed to be common in diabetic cats. However, studies in human diabetic patients over the past quarter century have rejected the common occurrence of this phenomenon. Therefore, we evaluated the occurrence and prevalence of rebound hyperglycaemia in diabetic cats. In a retrospective study, 10,767 blood glucose curves of 55 cats treated with glargine using an intensive blood glucose regulation protocol with a median of five blood glucose measurements per day were evaluated for evidence of rebound hyperglycaemic events, defined in two different ways (with and without an insulin resistance component). While biochemical hypoglycaemia occurred frequently, blood glucose curves consistent with rebound hyperglycaemia with insulin resistance was confined to four single events in four different cats. In 14/55 cats (25%), a median of 1.5% (range 0.32-7.7%) of blood glucose curves were consistent with rebound hyperglycaemia without an insulin resistance component; this represented 0.42% of blood glucose curves in both affected and unaffected cats. We conclude that despite the frequent occurrence of biochemical hypoglycaemia, rebound hyperglycaemia is rare in cats treated with glargine on a protocol aimed at tight glycaemic control. For glargine-treated cats, insulin dose should not be reduced when there is hyperglycaemia in the absence of biochemical or clinical evidence of hypoglycaemia. © ISFM and AAFP 2015.

    To describe factors associated with peri-operative blood transfusion (PBT) at radical cystectomy (RC) for patients with bladder cancer and evaluate its association on both early and late outcomes. Electronic records of treatment and surgical pathology reports were linked to the population-based Ontario Cancer Registry to identify all patients who underwent RC between 2000 and 2008. Modified Poisson regression model was used to determine the factors associated with PBT. A Cox-proportional hazards regression model was used to explore the association between PBT and overall (OS) and cancer-specific (CSS) survival. Among 2593 patients identified, 62% received an allogeneic red blood cell transfusion. The frequency of PBT decreased over the study period (from 68 to 54%, p < 0.001). Factors associated with PBT included age, sex, greater co-morbidity, stage, and surgeon volume. PBT was associated with inferior outcomes, including median length of stay (11 vs. 9 days, p < 0.001), 90-day re-admission rate (38 vs. 29%, p < 0.001), and mortality (11 vs. 4%, p < 0.001). OS and CSS at 5 years were lower among patients with PBT on multivariate analysis (OS HR 1.33, 95% CI 1.20-1.48; CSS HR 1.39, 95% CI 1.23-1.56). Although rates are decreasing, these data suggest a very high utilization rate of PBT at time of RC in routine clinical practice. PBT is associated with substantially worse early outcomes and long-term survival. This association persists despite adjustment for disease-, patient-, and provider-related factors, suggesting that PBT is an important indicator of surgical care of RC.

    2012-01-01

    Hyperglycaemia in patients with Acute Coronary Syndrome (ACS)is common, and is an independent predictor of mortality and morbidity in patients both with and without diabetes mellitus. Hyperglycaemia may be a marker of pre-existing diabetes or glucose intolerance or may also represent a transient stress response mediated through the autonomic nervous system with release of adrenal corticosteroids and catecholamines. Several evidences suggest that an intensive control of hyperglycaemia results in a significant improvement of the adverse outcomes in the short and long term. In fact, an intensive metabolic treatment can counteract the negative effects of hyperglycaemia. However, the main difficulty to intensive glucose control in patients with ACS remains hypoglycaemia that is associated with an increased risk of mortality and myocardial re-infarction. No definitive data are available about the beneficial effects of insulin intensive treatment. Therefore, randomized multicenter clinical trials will be needed to definitively establish whether intensive glucose control will reduce the associated increased mortality rate and higher rates of complications in hospitalized ACS patients with hyperglycaemia.

    2018-04-01

    : Obstructive sleep apnoea (OSA) is a common breathing disorder of sleep with a prevalence increasing in parallel with the worldwide rise in obesity. Alterations in sleep duration and architecture, hypersomnolence, abnormal gas exchange and also associated comorbidities may all feature in affected patients.The peri-operative period poses a special challenge for surgical patients with OSA who are often undiagnosed, and are at an increased risk for complications including pulmonary and cardiovascular, during that time. In order to ensure the best peri-operative management, anaesthetists caring for these patients should have a thorough understanding of the disorder, and be aware of the individual's peri-operative risk constellation, which depends on the severity and phenotype of OSA, the invasiveness of the surgical procedure, anaesthesia and also the requirement for postoperative opioids.The objective of this review is to educate clinicians in the epidemiology, pathogenesis and diagnosis of OSA in adults and also to highlight specific tasks in the preoperative assessment, namely to select a suitable intra-operative anaesthesia regimen, and manage the extent and duration of postoperative care to facilitate the best peri-operative outcome.

    Hyperglycaemia impairs many of the physiological processes involved in recovery from surgery but there is limited research on the effect of optimal peri-operative glucose control in diabetic general surgery patients. The objectives of this study were to assess blood glucose management in diabetic general surgical patients and to determine if protocol deviations were associated with adverse outcomes. All diabetic patients undergoing elective and emergency general surgical procedures between August 2007 and July 2008 were included in the study. The hospital protocol for peri-operative blood glucose control was based on the Alberti Regimen. Data was collected regarding blood glucose measurements, adherence to protocol and complications following surgery. A total of 69 adult patients (M = 44, F = 25; median age 61, range 15-93 years; T1DM = 35, T2DM = 34) were included. 38 patients underwent elective surgery (cholecystectomy, hernia repair, varicose vein surgery) and 31 underwent emergency surgical procedures (laparotomy, incision and drainage of abscess). 10.3% of capillary blood glucose readings were less than 6.1 mmol/l, 32.8% were between 6.1 and 10.0 mmol/l, 44.6% were greater than 10.0 mmol/l 12.3% of scheduled blood glucose measurements were not completed. An insulin-dextrose infusion was indicated in 30 patients, of which 14 (46.7%) were treated according to protocol. In the 16 protocol-deviation cases, insulin was generally either administered according to a sliding scale (6 patients) or not at all during their time on the ward. While an insulin-dextrose infusion was not indicated in 39 patients, 14 (35.9%) of these patients were inappropriately given insulin either as an infusion (8 patients) or according to a sliding scale (6 patients). Overall, only 39 (56.5%) patients were treated according to protocol. The overall complication rate was 29%, which included 7 out of 39 (17.9%) and 13 out of 30 (43.3%) protocol-based and protocol

    Stress hyperglycaemia, is a common phenomenon, frequently associated with adverse outcomes in a number of prevalent conditions including myocardial infarction and stroke. Knowledge on stress hyperglycaemia evolved in tandem with knowledge relating to homeostasis, stress and disease and involved some of the world's most eminent thinkers. Despite this, it still remains under-recognised. This paper illustrates significant points in the history of stress hyperglycaemia, from antiquity through to the present day, as well as the challenges faced in translating research into clinical benefit for patients. Profiles of significant protagonists including Claude Bernard, Walter Cannon and Hans Seyle are presented, as well their roles in the emergence of modern-day terminology and pathophysiological models. Major themes such as 'fight or flight' and homeostasis are central to this discussion. Closer to the present day, the role of stress hyperglycaemia in a number of common medical conditions is explored in more detail. Contention around evidence for treatment and the future risk of diabetes mellitus are also discussed.

    To evaluate the impact of fellows' involvement on the peri-operative outcomes of robot-assisted partial nephrectomy (RAPN). We analysed 216 patients who underwent RAPN for a small renal tumour. We stratified our cohort into two groups according to the involvement of a fellow surgeon during the procedure: expert surgeon operating alone (expert group) and fellow operating under the supervision of the expert surgeon (fellow group). Peri-operative data were compared between the two groups. Linear and logistic regression analyses were performed to assess the impact of fellows' involvement on peri-operative and postoperative outcomes. Trifecta and margins ischaemia complications (MIC) score achievement rates were used to assess the quality of surgery in both the expert and fellow groups. Trifecta was defined as a combination of warm ischaemia time <25 min, negative surgical margins and no peri-operative complications. MIC score was defined as negative surgical margins, ischaemia time <20 min, and absence of complications grade ≥3. Fellows were involved in a total of 89 procedures (41%). Patients' characteristics were similar in the two groups. Operating time and warm ischaemia time (WIT) were longer in the fellow group (180 vs 120 min, P < 0.001, and 18 vs 14 min, P = 0.002, respectively). Length of hospital stay (LOS) was longer in the fellow group (5 vs 4.3 days; P = 0.05) and patients in this group had higher estimated blood loss (EBL; 400 vs 300 mL; P = 0.01), but this had no impact on transfusion rate (14% vs 11%; P = 0.43). Positive surgical margin rates were similar in the fellow and expert groups (2.2% vs 3.1%; P = 0.70). Major complications were more frequent in the fellow group (12.3% vs 6.3%), but the difference was not significant (P = 0.10). In multivariable analysis, fellow involvement was predictive of longer WIT (β = 0.22; P = 0.003) and operating time (β = 0.49; P < 0.001), but was not associated with EBL (β = 0.12, P = 0.09) or LOS (β = 0.12, P

    Bariatric surgery is common in the Middle East region. However, regional accreditation bodies and guidelines are lacking. We present the current peri-operative practice of bariatric surgery in the Middle East region. Public and private practice in the Middle East region. A questionnaire was designed to study trends of peri-operative care in bariatric surgery. It was sent to members of the Pan Arab Society for Metabolic and Bariatric Surgery (PASMBS). Ninety-three surgeons (88.6%) responded, 63.4% were in private practice, 68.5% have been in practice for more than 5 years, and 61.1% performed more than 125 cases per year. Laparoscopic sleeve gastrectomy (LSG) was the commonest procedure performed, then laparoscopic Roux-en-Y gastric bypass (LRYGB), one anastomosis gastric bypass/mini gastric bypass (OAGB/MGB), and laparoscopic adjustable gastric banding (LAGB). Pre-operatively as a routine, 65% referred patients for dietitian and (78.3%) for smoking cessation. In contrast as a routine, 22.6% referred patients to a psychologist, 30% screened for obstructive sleep apnea (OSA), and when they did, they did not use a questionnaire. For patients 50 years of age, 22% performed a screening colonoscopy and 33.7% referred patients to a cardiologist. Intra-operatively as a routine, 25.3% placed a drain and 42.2% placed urinary catheters. In contrast, 77.1% performed a leak test (82.7% as a methylene blue leak test). Post-operatively, 79.5% used chemoprophylaxis for venous thromboembolism and 89% required patients to take vitamins. In contrast, 25% prescribed ursodeoxycholic acid. The wide variation in the peri-operative care of bariatric surgery in the Middle East region highlights the need for regional guidelines based on international guidelines.

    Full Text Available Anesthesiologists and intensivists are encountering increasing number of diabetic patients in daily clinical practice. Majority of such patients may require insulin injections for control of hyperglycemia. Advancements in diabetes management have led to usage of newer insulin injections ranging from human insulin and insulin analogs to glucagon-like peptides-1 analogs. The adequacy of glycemic control and successful outcome with such therapeutic interventions depends upon the adoption of correct injection techniques and procedures. Peri-operative and critically ill diabetic patients are highly prone to develop acute complications of diabetes if appropriate therapeutic strategies are not formulated and implemented. As such, the in-depth knowledge and awareness about various injection technique guidelines is essential from the patient care and healthcare provider′s perspective in the operative and critical care settings. This description is an abridged version of the Forum for Injection Techniques, India: The first Indian recommendations for best practice in insulin injection technique and their significance in peri-operative period and critically ill patients in intensive care units (ICU. These insulin injection techniques are based on evidence-based recommendations and are meant to improve the management of diabetes by the attending staff and physicians in operative and critical care arenas.

    To standardise possible peri-operative bariatric surgery protocols, a survey was prepared to be filled in by members of the Spanish Society for Obesity (Sociedad Española de Cirugía de la Obesidad) (SECO), and to approve it at the XII National Congress. A total of 47 members of SECO from 14 autonomous communities responded, and it unanimously approved by the Congress. As highly recommended peri-operative procedures, were proposed: full laboratory analysis (98%) with an endocrine study (90%), ECG (96%), chest x-ray (98%), an oesophageal-gastric imaging test (endoscopy or gastro-duodenal transit study (98%), antibiotic prophylaxis (92%) and use of low molecular weight heparins pre-operatively (96%), and for 2 weeks (83%). Pre-surgical, abdominal ultrasound (86%), spirometry (80%), diet (88%) and psychological study (76%), and during surgery, use of elastic stockings (76%), leak tests (92%) and drainages (90%), were established as advisable procedures.

    Full Text Available Aim. Surgical treatment of women due to gynaecological disorders is the cause of stress and may lead to psychological changes. Studies concerning human response to stress emphasize the importance of the effect of the level of the sense of coherence, anxiety, depression, dispositional optimism and skills of expressing emotions on the quality of feelings and experiences in difficult situations. Materials and methods. The study covered 232 women who had undergone gynaecological surgery due to various causes. Permission to conduct the research was obtained from the Bioethical Commission at the Medical University in Lublin. The study was carried out with the use of the State-Trait Anxiety Inventory (STAI, the Beck Depression Inventory, Courtauld Emotional Control Scale (CECS, and Life Orientation Test – Revised (LOT-R. Results and conclusions. The study showed that investigations of the sense of coherence, level of anxiety and depression, and personal resources allow determination of the characteristics of patients who should be covered with special psychoprophylactic care during the peri-operative period. In addition, the results of own studies obtained may be used for the development of adequate principles of psycho-prophylactic management in the course of the diagnostic-treatment proces with respect to women who had undergone surgical treatment due to gynaecological disorders.

    Full Text Available Nutrition is essential for maintenance of physiologic homeostasis and growth. Hypermetabolic states lead to a depletion of body stores, with decreased immunocompetence and increased morbidity and mortality. The purpose of this paper is to provide an update regarding the provision of appropriate nutrition for the pediatric surgical patient, emphasizing the preoperative and postoperative periods. Modern nutritional support for the surgical patient comprises numerous stages, including assessment of nutritional status, nutritional requirements, and nutritional therapy. Nutritional assessment is performed utilizing the clinical history, clinical examination, anthropometry, and biochemical evaluation. Anthropometric parameters include body weight, height, arm and head circumference, and skinfold thickness measurements. The biochemical evaluation is conducted using determinations of plasma levels of proteins, including album, pre-albumin, transferrin, and retinol-binding protein. These parameters are subject to error and are influenced by the rapid changes in body composition in the peri-operative period. Nutritional therapy includes enteral and/or parenteral nutrition. Enteral feeding is the first choice for nutritional therapy. If enteral feeding is not indicated, parenteral nutrition must be utilized. In all cases, an individualized, adequate diet (enteral formula or parenteral solution is obligatory to decrease the occurrence of overfeeding and its undesirable consequences.

    Dysphagia is usually a major problem for the elderly to go home after a surgical treatment for the bone fracture of the thigh bone cervix or trochanter part in the leg. We analyzed each clinical course with regard to a change of the oral intake and the nutritional status, the activity of daily living(ADL)and a nutritional management and the place after the patient was discharged. According to our results, about 20% of the patients among those surgical cases were pointed with dysphagia, and there were many cases that ADL was ultimately gotten worse. We took care of disphagia by doing a best practice of changing in feedings and deglutition function. However, some of the patients with the problem finally moved to another elderly health care institute against their primary wishes to go home. Furthermore, 55% of the disphagia patients became dementia. It seems that dementia might be a high risk factor of disphagia. We should do more better job for managing disphargia during a peri-operative period just after admission.

    Literature suggests that peri-operative blood transfusion among patients with resected colon cancer may be associated with inferior long-term survival. The study objective was to characterize this association in our population. This is a retrospective cohort study using the population-based Ontario Cancer Registry (2002-2008). Pathology reports were obtained for a 25% random sample of all cases and constituted the study population. Log binomial regression was used to identify factors associated with transfusion. Cox proportional hazards model explored the association between transfusion and cancer specific survival (CSS) and overall survival (OS). The study population included 7198 patients: 18% stage I, 36% stage II, 40% stage III, and 6% stage IV. Twenty-eight percent of patients were transfused. Factors independently associated with transfusion included advanced age (pTransfusion was associated with inferior CSS (HR 1.51, 95% CI 1.38-1.65) and OS (HR 1.52, 95% CI 1.41-1.63), after adjusting for important confounders. Peri-operative transfusion rates among patients with colon cancer have decreased over time. Transfusion is associated with inferior long-term CSS and OS. Copyright © 2017 Elsevier Ltd.

    Full Text Available Context: Traumatic aortic injury (TAI accounts for 1/3 of all trauma victims. Aim: We aimed to investigate the efficacy of the adopted standardized immediate pre-operative and intra-operative hemodynamic goal directed control, anesthetic technique and organs protection on the morbidity and mortality in patients presented with TAI. Settings and Design: An observational retrospective study at a single university teaching hospital. Materials and Methods: Following ethical approval, we recruited the data of 44 patients admitted to the King Fahd Hospital of the University, Al Khobar, Saudi Arabia, with formal confirmation of diagnosis of blunt TAI during a 5-year period from February 2008 to April 2013 from the hospital medical records. Statistical Analysis: descriptive analysis. Results: A total of 44 victims (41 men, median (range age 29 (22-34 years with TAI who underwent surgical repair were recruited. Median (range post-operative chest tube output was 700 (200-1100 ml necessitated transfusion in 5 (11.4% of cases. Post-operative complications included transient renal failure (13.6%, pneumonia (6.8%, acute lung injury/distress syndrome (20.5%, sepsis (4.5%, wound infection (47.7% and air leak (6.8%. No patient developed end stage renal failure or spinal cord injury. Median intensive care unit stay was 6 (4-30 days and in-hospital mortality was 9.1%. Conclusion: We found that the implementation of a standardized early goal directed hemodynamic control for the peri-operative management of patients with TAI reduces the post-operative morbidity and mortality after surgical repair.

    An American Academy of Neurology practice parameter recommends that long-term prophylactic anti-epileptic drugs (AED) should not be routine in patients with newly diagnosed brain tumors. However, prospective multi-center North American data shows that most newly diagnosed glioma patients receive prophylactic AED. We examined our own peri-operative AED practice patterns in newly-diagnosed patients with malignant glioma to determine if we deviate from published guidelines. A retrospective chart review was performed in adult patients with newly diagnosed malignant gliomas undergoing surgery in southern Alberta between January 2003 and December 2005. Demographic information, AED use, seizure incidence, adverse effects, tumor size, and tumor location were recorded. Of 164 eligible patients, 54 (33%) presented with seizures and all received AED. Prophylactic AED were given to 44 patients (27%). Peri-operative seizures (within 1 week) occurred in two patients without (3%) and no patients with seizure prophylaxis. Adverse AED reactions and adverse effects attributable to seizures were both rare. Prophylactic AED were continued >1 week post-op in 30 patients (18%). Patients receiving prophylactic AED were more likely to have had tumors involving the temporal lobe than those who did not (50 vs. 20%; P < 0.01). Patients receiving peri-operative AED prophylaxis were common, had a trend to reduced peri-operative seizures, and had few adverse effects. However, most of these patients were maintained on prophylactic AED continued beyond the first peri-operative week, contradicting published guidelines. Increased awareness of practice guidelines may help modify AED prescription patterns in malignant glioma patients.

    The objective of this study was to determine the factors responsible for peri-operative blood transfusion in a contemporary series of open prostatectomy for benign prostate hyperplasia and thus offer a guide for blood product management for the procedure. This was a prospective study of 200 consecutive patients who underwent open prostatectomy for BPH from January 2010 to September 2013 at the Korle Bu Teaching Hospital, Accra. The data analyzed included the pre-operative blood haemoglobin level (Hb), presence of co-morbidities, the case type, indication for the surgery, ASA score, anaesthetic method used, systolic blood pressure, status of the operating surgeon, duration of surgery and the operative prostate weight. The transfusion of blood peri-operatively was also documented. The mean age of the patients was 69.1 years. Elective cases formed 83.5 % with refractory retention of urine being the commonest indication for surgery (68.0 %). The mean pre-operative Hb was 12.1 g/dl. Consultants performed 56.0 % of the prostatectomies. Transvesical approach was used in 90.0 % of the cases. The mean operative time was 101.3mins (range 35.0-240.0) with a mean operative prostate weight of 110.8 g (range 15-550 g). Most of the patients (82.0 %) had spinal anaesthesia. The blood transfusion rate was 23.5 %. The transfusion rate was significantly higher in patients with anaemia (p = .000), emergency cases (p = .000), the use of general anaesthesia (p = .002), a resident as the operating surgeons (p = .034), prostate weight >100 g (p = .000) and duration of surgery (p = .011). In a multivariable logistic regression analysis however only the pre-operative Hb (p = .000. OR 0.95, 95 % CI [0.035-0.257]) and the duration of surgery (p = .025, OR 1.021, 95 % CI [1.003-1.039]) could predict blood transfusion in open prostatectomy for BPH in this series. A 'group and save' policy should be the preferred blood ordering procedure for patients

    There have been several recent studies on the correlation between intra-operative hypothermia and the occurrence of surgical site infection (SSI). Differences in the depth and timing of hypothermia and the surgical procedure may have led to conflicting results. Patients undergoing gastroenterologic surgery with a duration of >3 h were analyzed. Hypothermia was defined as a core temperature <36°C and was classified as mild (35.5-35.9°C), moderate (35.0-35.4°C), or severe (<35.0°C). Hypothermia also was classified as early-nadir (<36°C within two h of anesthesia induction) and late-nadir (after that time). Risk factors for SSIs were analyzed according to these classifications. Among 1,409 patients, 528 (37.5%) had hypothermia, which was classified as mild in 358, moderate in 137, and severe in 33. Early-nadir and late-nadir hypothermia was found in 23.7% and 13.8%, respectively. There was no significant difference in the incidence of SSIs between patients with and without hypothermia (relative risk 1.00; 95% confidence interval [CI] 0.80-1.25; p = 0.997). However, there was a significantly greater incidence of SSIs in patients with severe hypothermia (33.3%) than in those with normothermia (19.2%; p = 0.045) or mild hypothermia (17.0%; p = 0.021). The incidence of SSIs also was significantly greater in patients with late-nadir than in those with early-nadir hypothermia (23.7% vs. 16.5%; p = 0.041). The incidence of organ/space SSIs was significantly greater in patients with late-nadir hypothermia (19.6%) than in patients with normothermia (12.7%; p = 0.012). In multivariable analysis, neither severe hypothermia (odds ratio 1.24; 95% CI 0.56-2.77] nor late-nadir hypothermia (OR 0.71; 95% CI 0.46-1.01) was an independent risk factor for SSIs. Severe and late-nadir hypothermia were associated with a greater incidence of SSIs and organ/space SSIs. However, neither of these patterns was identified as an independent risk factor for SSIs, possibly

    The James Lind Alliance Anaesthesia and Peri-operative Care Priority Setting Partnership was a recent collaborative venture bringing approximately 2000 patients, carers and clinicians together to agree priorities for future research into anaesthesia and critical care. This secondary analysis compares the research priorities of 303 service users, 1068 clinicians and 325 clinicians with experience as service users. All three groups prioritised research to improve patient safety. Service users prioritised research about improving patient experience, whereas clinicians prioritised research about clinical effectiveness. Clinicians who had experience as service users consistently prioritised research more like clinicians than like service users. Individual research questions about patient experience were more popular with patients and carers than with clinicians in all but one case. We conclude that patients, carers and clinicians prioritise research questions differently. All groups prioritise research into patient safety, but service users also favour research into patient experience, whereas clinicians favour research into clinical effectiveness. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

    Adherent perirenal fat (APF) can be defined as inflammatory fat sticking to renal parenchyma, whose dissection is difficult and makes it troublesome to expose the tumour. Our objective was to evaluate the impact of APF on the technical difficulty of robot-assisted partial nephrectomy (RPN). We analysed data of 202 patients who underwent RPN for a small renal tumour. Patients were divided into two groups according to the presence of APF. Peri-operative data were compared between the two groups. Predictors of APF were evaluated by univariate and multivariate analysis. The validity of the MAP score (radiological scoring system) was also assessed. APF was observed in 80 patients (39.6 %). Tumour complexity and surgeon's experience were similar between both groups. Operative time was 40 min longer in the APF group (188.5 vs. 147.9 min, p < 0.0001). Blood loss was twice higher, and transfusions were more common in the APF group (694 vs. 330 ml, p < 0.0001 and 19 vs. 5.8 %, p = 0.003, respectively). APF was associated with an increased risk of conversion to open surgery (11.2 vs. 0 %, p = 0.0002) or radical nephrectomy (6.2 vs. 0.8 %, p = 0.03). In multivariate analysis, male gender (OR 13.2, p < 0.0001), obesity (OR 1.2, p = 0.007), hypertension (OR 3.7, p = 0.02), and MAP score (OR 3.3; p < 0.0001) were significant predictors of APF. During RPN, APF is associated with increased bleeding and a higher risk of conversion to open surgery and to radical nephrectomy. Male gender, hypertension, obesity, and MAP score are predictors of APF.

In February 2016, cephamycin drug shortages resulted in a change in The Johns Hopkins Hospital's (JHH) recommendation for peri-operative antibiotic prophylaxis in abdominal surgeries from cefotetan to cefazolin plus metronidazole. The primary objective of this study was to quantify the percentage of abdominal surgeries adherent to JHH peri-operative antibiotic prophylaxis guidelines. A sub-group analysis investigated whether prophylaxis with cefazolin plus metronidazole was associated with a lower rate of surgical site infections (SSIs) versus cefotetan. This retrospective cohort study included adult inpatients who underwent an abdominal surgery at JHH in September 2015 (Study Period I: cefotetan) or February to March 2016 (Study Period II: cefazolin plus metronidazole). Two hundred abdominal surgery cases were included in the primary analysis. A subset of 156 surgical cases were included in the sub-group analysis. The overall adherence rate to JHH guidelines was 75% in Study Period I versus 17% in Study Period II (p operative administration time (87% vs. 23%, p site infections occurred in 14% (12/83) of surgeries with cefotetan versus 8.2% (6/73) with cefazolin plus metronidazole for prophylaxis (p = 0.19). Adherence to an institution-specific peri-operative antibiotic prophylaxis guideline for abdominal surgeries was limited primarily by the longer infusion time required for pre-operative metronidazole. A higher percentage of SSIs occurred among abdominal surgeries with cefotetan versus cefazolin plus metronidazole for prophylaxis.

    To evaluate the peri-operative, functional and oncological outcomes of robot-assisted partial nephrectomy (RAPN) and laparoscopic partial nephrectomy (LPN) for moderately or highly complex tumours (defined as RENAL nephrometry score ≥7). We retrospectively analysed the medical charts of 216 patients with complex tumours who underwent LPN (n = 135) or RAPN (n = 81) between 2008 and 2014. Peri-operative data, pathological variables, complications, functional and oncological outcomes were reviewed. Demographic characteristics were similar in the two groups. LPN was associated with a longer operating time (149.6 vs 135.6 min; P = 0.017) and greater estimated blood loss (220.8 vs 196.5 mL; P = 0.013). RAPN was associated with a higher direct cost. There were no differences in warm ischaemia time, transfusion rate, conversion rate, hospital stay, operative complications and estimated glomerular filtration rate change at 6 months after surgery. The mean follow-ups for LPN and RAPN were 31.4 and 16.5 months, respectively. The 3-year recurrence-free survival rate was 95.2% for LPN and 97.1% for RAPN (P = 0.71). In patients with complex tumours, RAPN and LPN provided acceptable and similar results in terms of peri-operative, functional and oncological outcomes. RAPN was superior to LPN in terms of estimated blood loss and operating time, and LPN was the more cost-effective approach. Both surgery techniques remain viable options in the management of complex tumours with RENAL scores ≥7. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Full Text Available BACKGROUND The aim of the study is to determine the current practices in the medical college institutions pan India for testing for Hyperglycaemia in Pregnancy (HIP to detect gestational diabetes and highlight areas that need additional attention in order to ensure adherence to current national guidelines. MATERIALS AND METHODS Questionnaires were used to obtain information regarding the testing strategy for hyperglycaemia in pregnancy. The questionnaires were filled out by the teaching faculty of the OB/GYN departments of 47 medical college institutions in India. The perceptions regarding the prevalence of diabetes in pregnancy in India and the needs for capacity building were assessed. RESULTS Forty seven respondents answered the questionnaires. The majority of respondents (95.83% reported that all pregnant women were offered (universal testing for hyperglycaemia in pregnancy and 37.5% reported that women were screened both in early and midtrimester of pregnancy. Most reported that testing for HIP took place once at booking, irrespective of the gestational age (39.58%. Thirty three (70.21% respondents reported using the single-step nonfasting method to diagnose hyperglycaemia. Furthermore, 21.28% of respondents reported using a glucometer to determine the concentration of blood glucose in plasma, while 68.08% reported using a lab analyser. The instructions for the testing were offered by consultants and postgraduates in a vast majority of cases (87.5%. The staff communicated with the women in a significantly less number of cases (12.5%. 65.96% of respondents felt that all women readily agreed to follow this advice. The majority of respondents (89.35% reported having noticed an increase in the number of women with hyperglycaemia. Furthermore, 91% of all the respondents felt there was a need to train medical personnel to test and manage hyperglycaemia. CONCLUSION Our study confirms the continued wide variability in testing for HIP in India with

    Transfusion of blood products and mechanical ventilation with injurious settings are considered risk factors for postoperative lung injury in surgical Patients. A systematic review and individual patient data meta-analysis was done to determine the independent effects of peri-operative transfusion of blood products, intra-operative tidal volume and airway pressure in adult patients undergoing mechanical ventilation for general surgery, as well as their interactions on the occurrence of postoperative acute respiratory distress syndrome (ARDS). Observational studies and randomized trials were identified by a systematic search of MEDLINE, CINAHL, Web of Science, and CENTRAL and screened for inclusion into a meta-analysis. Individual patient data were obtained from the corresponding authors. Patients were stratified according to whether they received transfusion in the peri-operative period [red blood cell concentrates (RBC) and/or fresh frozen plasma (FFP)], tidal volume size [≤7 mL/kg predicted body weight (PBW), 7-10 and >10 mL/kg PBW] and airway pressure level used during surgery (≤15, 15-20 and >20 cmH 2 O). The primary outcome was development of postoperative ARDS. Seventeen investigations were included (3,659 patients). Postoperative ARDS occurred in 40 (7.2%) patients who received at least one blood product compared to 40 patients (2.5%) who did not [adjusted hazard ratio (HR), 2.32; 95% confidence interval (CI), 1.25-4.33; P=0.008]. Incidence of postoperative ARDS was highest in patients ventilated with tidal volumes of >10 mL/kg PBW and having airway pressures of >20 cmH 2 O receiving both RBC and FFP, and lowest in patients ventilated with tidal volume of ≤7 mL/kg PBW and having airway pressures of ≤15 cmH 2 O with no transfusion. There was a significant interaction between transfusion and airway pressure level (P=0.002) on the risk of postoperative ARDS. Peri-operative transfusion of blood products is associated with an increased risk of

    Full Text Available AIM: To compare the efficacy of ketoprofen and pethidine for peri-operative analgesia and post-operative nausea and vomiting in children undergoing vitreoretinal surgery and surgery for retinal detachment. MATERIAL AND METHODS: Children aged 7 to 16 years and ASA I status, undergoing vitreo-retinal surgery were randomly allocated to receive either ketoprofen 2mg/kg or pethidine 1mg/kg intravenously for peri-operative analgesia. In all patients, general anaesthesia was induced with thiopentone and intubation was facilitated with vecuronium bromide and maintained with 33% oxygen in nitrous oxide and isoflurane. Intra-operative and post-operative monitoring was done by an observer blinded to the technique. Intra-operative rescue analgesia was used if heart rate and/or blood pressure increased by 25% from pre-incision values. Post-operative pain and episodes of nausea and vomiting were evaluated at recovery (0 hour, 2, 6 and 24 hours intervals. Standard rescue analgesia and anti-emetic agents were administered if required. RESULTS: Eighty-six children were enrolled in the study. Forty-four received ketoprofen while 42 received pethidine. Intra-operative analgesia was comparable in both the groups and no significant difference was found in the requirement of intra-operative rescue analgesia, as well. Postoperatively 6/44 (13.6% children in ketoprofen group had pain at recovery compared to 17/42 (40.4% in pethidine group. Pain at 2, 6 and 24 hours, and postoperative analgesic requirement were not significantly different among the two groups. Post-operative nausea, vomiting, and antiemetic requirement were significantly less in the ketoprofen group at all time intervals. CONCLUSION: Ketoprofen is a satisfactory alternative analgesic to pethidine for vitreoretinal surgery and results in a lower incidence of postoperative nausea and vomiting.

    Women with hyperglycaemia detected during pregnancy are at greater risk for adverse pregnancy outcomes. Data on hyperglycaemia in pregnancy in sub-Saharan Africa is scanty and varied depending on the populations studied and the methodologies used to define hyperglycaemia in pregnancy. With the recent 2013 World Health Organisation (WHO) diagnostic criteria and classification, there is yet no sufficient data on the prevalence of hyperglycaemia in sub-Saharan Africa. The objective was to determine the prevalence of Hyperglycaemia first detected during pregnancy and subsequent obstetric outcomes among patients attending antenatal care (ANC) at St. Francis Hospital Nsambya. A prospective cohort study. All women with no history of diabetes mellitus attending at or after 24 weeks gestation were eligible to participate in the study. Participants underwent a standard 75 g oral glucose tolerance test (OGTT) after an informed written consent. The primary outcome was diagnosis of hyperglycaemia. Enrolled participants were followed up to delivery to assess obstetric outcomes (secondary outcomes were birth weight, neonatal admission, maternal genital trauma, delivery mode, neonatal and maternal status at discharge). 251 women were screened between December 2013 and February 2014. The prevalence of hyperglycaemia first detected in pregnancy was 31.9%. We found 23.8 % of women with hyperglycaemia had no known risk factor. Macrosomia was the only obstetric outcome that was significantly associated with hyperglycaemia. The prevalence of hyperglycaemia first detected in pregnancy was high in the studied population. Clinicians, therefore, should become more vigilant to screen for the condition. Selective screening may miss 23.8% of pregnant women with hyperglycaemia. However the cost/benefit implications of screening strategy and the recent 2013 WHO diagnostic criteria need to be studied in our setting.

    Full Text Available Though multiple single nucleotide polymorphisms (SNPs associated with type 2 diabetes have been identified, the genetic bases of isolated fasting hyperglycaemia (IFH and isolated postprandial hyperglycaemia (IPH were still unclear. In present study, we aimed to investigate the association of genome-wide association study-validated genetic variants and IFH or IPH in Han Chinese.We genotyped 27 validated SNPs in 6,663 unrelated individuals comprising 341 IFH, 865 IPH, 1,203 combined fasting hyperglycaemia and postprandial hyperglycaemia, and 4,254 normal glycaemic subjects of Han ancestry. The distributions of genotype frequencies of FTO, CDKAL1 and GCKR were significant different between individuals with IFH and those with IPH (SNP(ptrend : rs8050136(0.0024, rs9939609(0.0049, rs7756992(0.0122, rs780094(0.0037. Risk allele of FTO specifically increased the risk of IFH (rs8050136: OR 1.403 [95% CI 1.125-1.750], p = 0.0027; rs9939609: 1.398 [1.120-1.744], p = 0.0030. G allele of CDKAL1 specifically increased the risk of IPH (1.217 [1.092-1.355], p = 0.0004. G allele of GCKR increased the risk of IFH (1.167 [0.999-1.362], p = 0.0513, but decreased the risk of IPH (0.891 [0.801-0.991], p = 0.0331. In addition, TCF7L2 and KCNQ1 increased the risk of both IFH and IPH. When combined, each additional risk allele associated with IFH increased the risk for IFH by 1.246-fold (p<0.0001, while each additional risk allele associated with IPH increased the risk for IPH by 1.190-fold (p<0.0001.Our results indicate that genotype distributions of variants from FTO, GCKR, CDKAL1 were different between IPH and IFH in Han Chinese. Variants of genes modulating insulin sensitivity (FTO, GCKR contributed to the risk of IFH, while variants of genes related to beta cell function (CDKAL1 increase the risk of IPH.

    Significant advances in cardiac intensive care including extracorporeal life support have enabled children with complex congenital heart disease and end-stage heart failure to be supported while awaiting transplantation. With an increasing number of survivors after heart transplantation in children, the complications from long-term immunosuppression, including renal insufficiency, are becoming more apparent. Severe renal dysfunction after heart transplant is defined by a serum creatinine level >2.5 mg/dL (221 μmol/L), and/or need for dialysis or renal transplant. The degree of renal dysfunction is variable and is progressive over time. About 3-10 % of heart transplant recipients will go on to develop severe renal dysfunction within the first 10 years post-transplantation. Multiple risk factors for chronic kidney disease post-transplant have been identified, which include pre-transplant worsening renal function, recipient demographics and morbidity, peri-transplant haemodynamics and long-term exposure to calcineurin inhibitors. Renal insufficiency increases the risk of post-transplant morbidity and mortality. Hence, screening for renal dysfunction pre-, peri- and post-transplantation is important. Early and timely detection of renal insufficiency may help minimize renal insults, and allow prompt implementation of renoprotective strategies. Close monitoring and pre-emptive management of renal dysfunction is an integral aspect of peri-transplant and subsequent post-transplant long-term care.

    The number of people with diabetes using continuous subcutaneous insulin infusions (CSII) with an insulin pump has risen dramatically, creating new challenges when these patients are admitted to the hospital for surgical or other procedures. There is limited literature guiding CSII use during surgical procedures. The study was carried out in a large, urban, tertiary care hospital. We enrolled 49 patients using insulin pump therapy presenting for 57 elective surgeries. We developed a CSII peri-operative glycemic management protocol (PGMP) to standardize insulin pump management in patients admitted to a same-day surgery unit (SDSU). The purpose was evaluate the safety (% capillary blood glucose (CBG) operative steroid use on postoperative glycemic control. Overall, 63% of patients treated according to the CSII PGMP had a first postoperative CBG ≤200 mg/dL. There were no episodes of intra- or postoperative hypoglycemia. For patients treated with the CSII PGMP, the mean postoperative CBG was lower in patients with anticipated or actual surgical length ≤120 minutes (158.1 ± 53.9 vs. 216 ± 77.7 mg/dL, P<.01). No differences were observed with admission CBG, type of anesthesia, or steroid use. This study demonstrates that a CSII PGMP is both safe and effective for patients admitted for elective surgical procedures and provides an example of a standardized protocol for use in clinical practice.

    Full Text Available The aim of this study was to identify risk factors associated with confirmed fatal hyperglycaemia, which could predispose potentially preventable deaths in individuals on glucose lowering drugs.A retrospective register-based case-control study conducted on a nationwide cohort with individuals who died due to hyperglycaemia as determined by forensic postmortem examination, in Sweden August 2006 to December 2012. Vitreous glucose was used to diagnose hyperglycaemia postmortem. The forensic findings stored in the National Forensic Medicine Database were linked to nationwide registers. Cases that died due to confirmed hyperglycemia with dispensed glucose lowering drugs were identified and living controls with dispensed glucose lowering drugs were randomly selected in the Swedish prescribed drug register and matched on age and sex. Information on comorbidities, dispensed pharmaceuticals, clinical data and socioeconomic factors were obtained for cases and controls. Adjusted multiple logistic regression models were used to identify risk factors associated with fatal hyperglycaemia.During the study period 322 individuals, mostly males (79% with the mean age of 53.9 years (SD.± 14 died due to confirmed hyperglycaemia. Risk factors for fatal hyperglycaemia included; insulin treatment (OR = 4.40; 95%CI,1.96, 9.85, poor glycaemic control (OR = 2.00 95%CI,1.23, 3.27, inadequate refill-adherence before death (OR = 3.87; 95%CI,1.99, 7.53, microvascular disease (OR = 3.26; 95% CI, 1.84, 5.79, psychiatric illness (OR = 2.30; 95% CI,1.32, 4.01, substance abuse (OR = 8.85; 95%CI,2.34, 35.0 and/or living alone (OR = 2.25; 95%CI,1.21, 4.18.Our results demonstrate the importance of clinical attention to poor glycaemic control in subjects with psychosocial problems since it may indicate serious non-adherence, which consequently could lead to fatal hyperglycaemia.

    We report a case of hyperglycaemia and ketosis developing in a non-diabetic patient who underwent a neurosurgical procedure under general anaesthesia. A 52-year-old non-diabetic female patient underwent excision of acoustic neuroma under general anaesthesia. Pancreatic function was not disturbed and she received a single dose of dexamethasone (8 mg) and paracetamol (1 g). Delayed recovery from anaesthesia occurred. On investigation, she was found to have hyperglycaemia and ketosis. She was further managed on the line of diabetic ketoacidosis. After 24 hours, when blood glucose had normalised and ketosis abated, she could be weaned from mechanical ventilation and extubated. The patient did not receive any drugs known to cause such a condition. To the best of our knowledge, hyperglycaemia and ketosis developing in a non-diabetic patient causing delayed recovery and extubation is here reported for the first time.

    This study was designed to assess anti-diabetic potential of goat, camel, cow and buffalo milk in streptozotocin (STZ) induced type 1 diabetic albino wistar rats. A total of 48 rats were taken for the study where one group was kept as non-diabetic control group (8 rats) while others (40 rats) were made diabetic by STZ (50 mg/kg of body weight) injection. Among diabetic rats, a control group (8 rats) was kept and referred as diabetic control whereas other four groups (8 rats each) of diabetic rats were fed on 50 ml of goat or camel or cow or buffalo milk for 4 weeks. All the rats (non-diabetic and diabetic) were maintained on standard diet for four weeks. STZ administration resulted in enhancement of glucose, total cholesterol, triglyceride, low density lipoprotein, HbA1c and reduction in high density lipoprotein in plasma and lowering of antioxidative enzymes (catalase, glutathione peroxidase and superoxide dismutase) activities in pancreas, kidney, liver and RBCs, coupled with enhanced levels of TBARS and protein carbonyls in pancreas, kidney, liver and plasma. OGTT carried out at the end of 4 week milk feeding indicated that all milks helped in early maintenance of glucose level. All milks reduced atherogenic index. In camel milk fed diabetic group, insulin concentration enhanced to level noted for non-diabetic control while goat, cow and buffalo milk failed to restore insulin level. HbA1c level was also restored only in camel milk fed diabetic group. The level of antioxidative enzymes (catalase, GPx and SOD) in pancreas enhanced in all milk fed groups. Camel milk and to a reasonable extent goat milk reduced formation of TBARS and PCs in tissues and blood. It can be concluded that camel milk ameliorates hyperglycaemia and oxidative damage in type-1 diabetic experimental rats. Further, only camel milk completely ameliorated oxidative damage in pancreas and normalised insulin level.

    Pregestational diabetes mellitus (PGDM) enhances the risk of fetal neurodevelopmental defects. However, the mechanism of hyperglycaemia-induced neurodevelopmental defects is not fully understood. In this study, several typical neurodevelopmental defects were identified in the streptozotocin-induced diabetes mouse model. The neuron-specific class III beta-tubulin/forkhead box P1-labelled neuronal differentiation was suppressed and glial fibrillary acidic protein-labelled glial cell lineage differentiation was slightly promoted in pregestational diabetes mellitus (PGDM) mice. Various concentrations of glucose did not change the U87 cell viability, but glial cell line-derived neurotrophic factor expression was altered with varying glucose concentrations. Mouse maternal hyperglycaemia significantly increased Tunel{sup +} apoptosis but did not dramatically affect PCNA{sup +} cell proliferation in the process. To determine the cause of increased apoptosis, we determined the SOD activity, the expression of Nrf2 as well as its downstream anti-oxidative factors NQO1 and HO1, and found that all of them significantly increased in PGDM fetal brains compared with controls. However, Nrf2 expression in U87 cells was not significantly changed by different glucose concentrations. In mouse telencephalon, we observed the co-localization of Tuj-1 and Nrf2 expression in neurons, and down-regulating of Nrf2 in SH-SY5Y cells altered the viability of SH-SY5Y cells exposed to high glucose concentrations. Taken together, the data suggest that Nrf2-modulated antioxidant stress plays a crucial role in maternal hyperglycaemia-induced neurodevelopmental defects. - Highlights: • Typical neurodevelopmental defects could be observed in STZ-treated mouse fetuses. • Nrf2 played a crucial role in hyperglycaemia-induced brain malformations. • The effects of hyperglycaemia on neurons and glia cells were not same.

    Studies have started to question whether a specific component or combinations of metabolic syndrome (MetS) components may be more important in relation to cardiovascular disease risk. Our aim was to examine the impact of the presence of raised fasting glucose as a MetS component on postprandial lipaemia. Men classified with the MetS underwent a sequential test meal investigation, in which blood samples were taken at regular intervals after a test breakfast (t=0 min) and lunch (t=330 min). Lipids, glucose and insulin were measured in the fasting and postprandial samples. MetS subjects with 3 or 4 components were subdivided into those without (n=34) and with (n=23) fasting hyperglycaemia (≥5.6 mmol/l), irrespective of the combination of components. Fasting lipids and insulin were similar in the two groups, with glucose significantly higher in the men with glucose as a MetS component (Ppostprandial triacylglycerol (TAG) response in men with fasting hyperglycaemia. Greater glucose AUC (Ppostprandial TAG and glucose response. Our data analysis has revealed a greater impairment of postprandial TAG than glucose response in MetS subjects with raised fasting glucose. The worsening of postprandial lipaemic control may contribute to the greater CVD risk reported in individuals with MetS component combinations which include hyperglycaemia.

    2011-01-01

    AIMS/HYPOTHESIS: Type 2 diabetes is caused by relative deficiency of insulin secretion and is associated with dysregulation of glucagon secretion during the late stage of diabetes development. Like insulin secretion from beta cells, glucagon secretion is dependent on calcium signals and a calcium...... sensing protein, synaptotagmin-7. In this study, we tested the relative contribution of dysregulated glucagon secretion and reduced insulin release in the development of hyperglycaemia and type 2 diabetes by using synaptotagmin-7 knockout (KO) mice, which exhibit glucose intolerance, reduced insulin...... secretion and nearly abolished Ca(2+)-stimulated glucagon secretion. METHODS: We fed the synaptotagmin-7 KO and control mice with a high-fat diet (HFD) for 14 weeks, and compared their body weight, glucose levels, glucose and insulin tolerance, and insulin and glucagon secretion. RESULTS: On the HFD...

    Insulin treatment of individuals with type 1 diabetes has shortcomings and many patients do not achieve glycaemic and metabolic targets. Consequently, the focus is on novel non-insulin therapeutic approaches that reduce hyperglycaemia and improve metabolic variables without increasing the risk...... with few participants; evidence for the efficacy of concomitant treatments is scarce and largely clinically insignificant. A subgroup of patients with type 1 diabetes for whom non-insulin antidiabetic drugs could significantly benefit glycaemic control cannot yet be defined, but we suggest that obese...

    2017-02-01

    Terminalia catappa has shown potent antidiabetic activity in the past; however, the exact molecular mechanisms by which it acts have not been elucidated. This review aims at exploring several hypotheses which have been proposed to explain its mechanism of action, including reduction in oxidative stress, inflammation, angiogenesis, lipid profile correction and direct hypoglycaemic actions. A thorough review of all the articles, research as well as reviews, available regarding the concerned topic was performed. MEDLINE databases were searched using keywords (and their combinations), such as T. catappa, renin oxidative stress, inflammation, angiogenesis, diabetic retinopathy, α-glucosidase and α-amylase, among several others. English-language articles were preferably selected. Apart from metabolic dysfunctions, several hyperglycaemia-induced pathological conditions come into scene as the after-effects of diabetes. These mainly include inflammation, oxidative stress, angiogenesis and lipid profile alteration, which ultimately result in vascular endothelial dysfunction, hepatic steatosis, lipid peroxidation and apoptosis of endothelial, hepatic and neuronal cells. Terminalia catappa effectively attenuates the progression of diabetic retinopathy and shows significant hypoglycaemic actions. The mechanisms behind these effects were explained. Terminalia catappa may provide an effective natural product to treat hyperglycaemia and prevent subsequent diabetic complications. © 2016 Royal Pharmaceutical Society.

    Diabetic hyperglycaemia causes endothelial dysfunction mainly by impairing endothelial nitric oxide (NO) production. Moreover, hyperglycaemia activates several noxious cellular pathways including apoptosis, increase in reactive oxygen species (ROS) levels and diminishing Na(+)-K(+) ATPase activity which exacerbate vascular damage. Serum glucocorticoid kinase (SGK)-1, a member of the serine/threonine kinases, plays a pivotal role in regulating NO production through inducible NO synthase activation and other cellular mechanisms. Therefore, in this study, we aimed to investigate the protective role of SGK-1 against hyperglycaemia in human umbilical endothelial cells (HUVECs). We used retrovirus to infect HUVECs with either SGK-1, SGK-1Δ60 (lacking of the N-60 amino acids-increase SGK-1 activity) or SGK-1Δ60KD (kinase-dead constructs). We tested our hypothesis in vitro after high glucose and glucosamine incubation. Increase in SGK-1 expression and activity (SGK-1Δ60) resulted in higher production of NO, inhibition of ROS synthesis and lower apoptosis in endothelial cell after either hyperglycaemia or glucosamine treatments. Moreover, in this study, we showed increased GLUT-1 membrane translocation and Na(+)-K(+) ATPase activity in cell infected with SGK-1Δ60 construct. These results suggest that as in endothelial cells, an increased SGK-1 activity and expression reduces oxidative stress, improves cell survival and restores insulin-mediated NO production after different noxae stimuli. Therefore, SGK-1 may represent a specific target to further develop novel therapeutic options against diabetic vascular disease.

    Oxidative stress plays a pivotal role in the development of diabetes and hyperglycaemia. The protective effects of natural extracts against diabetes are mainly dependent on their antioxidant and hypoglycaemic properties. Broccoli ( Brassica oleracea ) exerts beneficial health effects in several diseases including diabetes; however, the mechanism has not been elucidated yet. The present study was carried out to evaluate the potential hypoglycaemic and antioxidant properties of aqueous broccoli extracts (BEs) in diabetic rats. Streptozotocin (STZ) drug was used as a diabetogenic agent in a single intraperitoneal injection dose of 50 mg/kg body weight. The blood glucose level for each rat was measured twice a week. After 8 weeks, all animals were fasted overnight and sacrificed; pancreatic tissues were homogenized and used for measuring oxidative DNA damage, biochemical assessment of glutathione (GSH), and total antioxidant capacity (TAC) as well as histopathological examination for pancreatic tissues was examined. Diabetic rats showed significantly higher levels of DNA damage, GSH depletion, and impaired TAC levels in comparison to non-diabetics ( P <0.05). The treatment of diabetic rats with BE significantly reduced DNA damage and conserved GSH and TAC values ( P <0.01). BE attenuated pancreatic histopathological changes in diabetic rats. The results of this study indicated that BE reduced the STZ mediated hyperglycaemia and the STZ-induced oxidative injury to pancreas tissue. The used in vivo model confirmed the efficacy of BE as an anti-diabetic herbal medicine and provided insights into the capacity of BE to be used for phytoremediation purposes for human type 2 diabetes.

    Full text: Recent studies have demonstrated that acute changes in the blood glucose concentration may affect gastrointestinal motor function and the perception of sensations arising from the gastrointestinal tract. Erythromycin has been shown to accelerate gastric emptying in both normal subjects and patients with diabetes mellitus. The major aims of this study were to determine in normal subjects whether the effects of erythromycin on gastric emptying, and perceptions of hunger and fullness are modified by the blood glucose concentration. 10 normal subjects (aged 20-39 yr) underwent concurrent measurement of gastric emptying, blood glucose, hunger and fullness on four separate occasions: twice during euglycaemia (∼4 mmol/L) and twice during hyperglycaemia (∼15 mmol/L). Either erythromycin (3 mg/kg) or saline (0.9%) was administered intravenously immediately before ingestion of a radioisotopically labelled solid meal. Gastric emptying was slower (P<0.0001) during hyperglycaemia when compared to euglycaemia after both erythromycin and saline administration. Erythromycin accelerated the post-lag emptying rate during euglycaemia (P<0.05), but not hyperglycaemia. Hunger decreased (P<0.001) and fullness increased (P<0.001) after the meal Postprandial hunger was less (P<0.05) and fullness greater (P<0.05 during hyperglycaemia after saline infusion, but not after erythromycin. Hunger was greater after erythromycin when compared to saline during both hyperglycaemia and euglycaemia (P<0.05). In conclusion, at a blood glucose concentration of ∼15 mmol/L when compared to euglycaemia: (i) after administration of erythromycin (3 mg/kg IV) gastric emptying of a solid meal is much slower, (ii) the effect of erythromycin on gastric emptying of a solid meal is attenuated and (iii) the perception of postprandial hunger is reduced and that of fullness increased

    To investigate the joint influence of physical activity and family history of diabetes on the subsequent risk of developing hyperglycaemia and Type 2 diabetes among Chinese adults. A prospective community-based cohort study was conducted among adults aged 35 years and older during 2004-2007 in Nanjing, China. Four communities (three urban and one rural) were randomly selected from 11 urban districts and two rural counties. Hyperglycaemia and Type 2 diabetes were defined using World Health Organization criteria based on fasting blood glucose concentration and physicians' diagnosis, respectively. Physical activity, parental diabetes history, and other important covariates were assessed at baseline and in the third-year follow-up survey. At study conclusion data were collected from 3031 participants (follow-up rate 81.3%). The 3-year cumulative incidence of hyperglycaemia and Type 2 diabetes was 6.2% and 2.4%, respectively. After adjustment for potential confounding variables, compared with those with positive family history and insufficient physical activity, the adjusted relative risk ratio (95% CI) of developing hyperglycaemia was 0.19 (0.02, 1.51) for participants with sufficient physical activity and a positive family history; 0.55 (0.31, 0.97) for participants with insufficient physical activity and a negative family history; and 0.36 (0.19, 0.70) for participants with sufficient physical activity but a negative family history. Participants who had a negative family history and insufficient physical activity were also less likely to develop Type 2 diabetes (RRR = 0.28; 0.14, 0.54), and participants with a negative family history and sufficient physical activity were the least likely to develop Type 2 diabetes (0.23; 0.10, 0.56). Sufficient physical activity and negative family history of diabetes may jointly reduce the risk of developing hyperglycaemia and Type 2 diabetes in Chinese adults. © 2011 The Authors.

    FDG PET in hyperglycaemic subjects often suffers from limited statistical image quality, which may hamper visual and quantitative evaluation. In our study the following insulin bolus protocol is proposed for acute correction of hyperglycaemia (> 7.0 mmol/l) in brain FDG PET. (i) Intravenous bolus injection of short-acting insulin, one I.E. for each 0.6 mmol/l blood glucose above 7.0. (ii) If 20 min after insulin administration plasma glucose is ≤ 7.0 mmol/l, proceed to (iii). If insulin has not taken sufficient effect step back to (i). Compute insulin dose with the updated blood glucose level. (iii) Wait further 20 min before injection of FDG. (iv) Continuous supervision of the patient during the whole scanning procedure. The potential of this protocol for improvement of image quality in brain FDG PET in hyperglycaemic subjects was evaluated by computer simulations within the Sokoloff model. A plausibility check of the prediction of the computer simulations on the magnitude of the effect that might be achieved by correction of hyperglycaemia was performed by retrospective evaluation of the relation between blood glucose level and brain FDG uptake in 89 subjects in whom FDG PET had been performed for diagnosis of Alzheimer's disease. The computer simulations suggested that acute correction of hyperglycaemia according to the proposed bolus insulin protocol might increase the FDG uptake of the brain by up to 80%. The magnitude of this effect was confirmed by the patient data. The proposed management protocol for acute correction of hyperglycaemia with insulin has the potential to significantly improve the statistical quality of brain FDG PET images. This should be confirmed in a prospective study in patients. (orig.)

    The incidence of many common cancers varies between different populations and appears to be affected by a Western lifestyle. Highly proliferative malignant cells require sufficient levels of nutrients for their anabolic activity. Therefore, targeting genes and pathways involved in metabolic pathways could yield future therapeutics. A common pathway implicated in energetic and nutritional requirements of a cell is the LKB1/AMPK pathway. Metformin is a widely studied anti-diabetic drug, which improves glycaemia in patients with type 2 diabetes by targeting this pathway. We investigated the effect of metformin on prostate cancer cell lines and evaluated its mechanism of action using DU145, LNCaP, PC3 and VCaP prostate cancer cell lines. Trypan blue dye-exclusion assay was used to assess levels of cell death. Western immunoblotting was used to determine the abundance of proteins. Insulin-like growth factor-binding protein-2 (IGFBP-2) and AMPK genes were silenced using siRNA. Effects on cell morphology were visualised using microscopy. IGFBP-2 gene expression was assessed using real-time RT-PCR. With DU145 and LNCaP cells metformin alone induced cell death, but this was reduced in hyperglycaemic conditions. Hyperglycaemia also reduced the sensitivity to Docetaxel, but this was countered by co-treatment with metformin. LKB1 was required for the activation of AMPK but was not essential to mediate the induction of cell death. An alternative pathway by which metformin exerted its action was through downregulation of IGFBP-2 in DU145 and LNCaP cells, independently of AMPK. This finding could have important implications in relation to therapeutic strategies in prostate cancer patients presenting with diabetes. © 2017 The authors.

    Patients with type 2 diabetes mellitus have a higher risk of dental and/or orthopaedic implant failure. However, the mechanism behind this phenomenon is unclear, and animal studies may prove useful in shedding light on the processes involved. This review considers the available literature on rat models of diabetes and titanium implantation. The process of osseointegration whereby direct contact is achieved between bone and an implant surface depends on healthy bone metabolism. Collective evidence suggests that hyperglycaemia adversely affects bone turnover and the quality of the organic matrix resulting in an overall deterioration in the quality, resilience and structure of the bone tissue. This in turn results in compromised osseointegration in patients receiving dental and orthopaedic implants. The incidence of diabetes mellitus (DM), which is a chronic metabolic disorder resulting in hyperglycaemia, is rising. Of particular significance is the rising incidence of adult onset type 2 diabetes mellitus (T2DM) in an ageing population. Understanding the effects of hyperglycaemia on osseointegration will enable clinicians to manage health outcomes for patients receiving implants. Much of our understanding of how hyperglycaemia affects osseointegration comes from animal studies. In this review, we critically analyse the current animal studies. Our review has found that most studies used a type 1 diabetes mellitus (T1DM) rodent model and looked at a young male population of rodents. The pathophysiology of T1DM is however very different to that of T2DM and is not representative of T2DM, the incidence of which is rising in the ageing adult population. Genetically modified rats have been used to model T2DM, but none of these studies have included female rats and the metabolic changes in bone for some of these models used are not adequately characterized. Therefore, the review suggests that the study population needs to be broadened to include both T1DM and T2DM models

    2014-08-01

    Full Text Available Purpose of review: Acute kidney injury (AKI is common after major surgery, and is associated with morbidity, mortality, increased length of hospital stay, and high health care costs. Although recent guidelines for AKI provide recommendations for identification of patients at risk, monitoring, diagnosis, and management of AKI, there is lack of understanding to guide successful implementation of these recommendations into clinical practice. Sources of information: We held a planning meeting with multidisciplinary stakeholders to identify barriers, facilitators, and strategies to implement recommendations for prevention, early identification, and management of AKI after major surgery. Barriers and facilitators to knowledge use for peri-operative AKI prevention and care were discussed. Findings: Stakeholders identified barriers in knowledge (how to identify high-risk patients, what criteria to use for diagnosis of AKI, attitudes (self-efficacy in preventive care and management of AKI, and behaviors (common use of diuretics, non-steroidal anti-inflammatory drugs, withholding of intravenous fluids, and competing time demands in peri-operative care. Educational, informatics, and organizational interventions were identified by stakeholders as potentially useful elements for future interventions for peri-operative AKI. Limitation: Meeting participants were from a single centre. Implications: The information and recommendations obtained from this stakeholder's meeting will be useful to design interventions to improve prevention and early care for AKI after major surgery.

Cox models estimated hazard ratios for diabetes treatments adjusting for potential confounders. Results 21 308 (4.5%) and 32 533 (6.9%) patients received prescriptions for glitazones and gliptins during follow-up, respectively. Compared with non-use, glitazones were associated with a decreased risk of blindness (adjusted hazard ratio 0.71, 95% confidence interval 0.57 to 0.89; rate 14.4 per 10 000 person years of exposure) and an increased risk of hypoglycaemia (1.22, 1.10 to 1.37; 65.1); gliptins were associated with a decreased risk of hypoglycaemia (0.86, 0.77 to 0.96; 45.8). Although the numbers of patients prescribed gliptin monotherapy or glitazones monotherapy were relatively low, there were significantly increased risks of severe kidney failure compared with metformin monotherapy (adjusted hazard ratio 2.55, 95% confidence interval 1.13 to 5.74). We found significantly lower risks of hyperglycaemia among patients prescribed dual therapy involving metformin with either gliptins (0.78, 0.62 to 0.97) or glitazones (0.60, 0.45 to 0.80) compared with metformin monotherapy. Patients prescribed triple therapy with metformin

    Complex chemical processes termed non-enzymic glycation that operate in vivo and similar chemical interactions between sugars and proteins that occur during thermal processing of food (known as the Maillard reaction) are one of the interesting examples of a potentially-harmful interaction between nutrition and disease. Non-enzymic glycation comprises a series of reactions between sugars, alpha-oxoaldehydes and other sugar derivatives and amino groups of amino acids, peptides and proteins leading to the formation of heterogeneous moieties collectively termed advanced glycation end products (AGE). AGE possess a wide range of chemical and biological properties and play a role in diabetes-related pathology as well as in several other diseases. Diabetes is, nevertheless, of particular interest for several reasons: (1) chronic hyperglycaemia provides the substrates for extracellular glycation as well as intracellular glycation; (2) hyperglycaemia-induced oxidative stress accelerates AGE formation in the process of glycoxidation; (3) AGE-modified proteins are subject to rapid intracellular proteolytic degradation releasing free AGE adducts into the circulation where they can bind to several pro-inflammatory receptors, especially receptor of AGE; (4) kidneys, which are principally involved in the excretion of free AGE adducts, might be damaged by diabetic nephropathy, which further enhances AGE toxicity because of diminished AGE clearance. Increased dietary intake of AGE in highly-processed foods may represent an additional exogenous metabolic burden in addition to AGE already present endogenously in subjects with diabetes. Finally, inter-individual genetic and functional variability in genes encoding enzymes and receptors involved in either the formation or the degradation of AGE could have important pathogenic, nutrigenomic and nutrigenetic consequences.

    Full Text Available Background: Ethnic minorities in Europe have high susceptibility to type 2 diabetes (T2DM and, in some groups, also cardiovascular disease (CVD. Pregnancy can be considered a stress test that predicts future morbidity patterns in women and that affects future health of the child. Objective: To review ethnic differences in: 1 adiposity, hyperglycaemia, and pre-eclampsia during pregnancy; 2 future risk in the mother of obesity, T2DM and CVD; and 3 prenatal development and possible influences of maternal obesity, hyperglycaemia, and pre-eclampsia on offspring's future disease risk, as relevant for ethnic minorities in Europe of Asian and African origin. Design: Literature review. Results: Maternal health among ethnic minorities is still sparsely documented. Higher pre-pregnant body mass index (BMI is found in women of African and Middle Eastern descent, and lower BMI in women from East and South Asia compared with women from the majority population. Within study populations, risk of gestational diabetes mellitus (GDM is considerably higher in many minority groups, particularly South Asians, than in the majority population. This increased risk is apparent at lower BMI and younger ages. Women of African origin have higher risk of pre-eclampsia. A GDM pregnancy implies approximately seven-fold higher risk of T2DM than normal pregnancies, and both GDM and pre-eclampsia increase later risk of CVD. Asian neonates have lower birth weights, and mostly also African neonates. This may translate into increased risks of later obesity, T2DM, and CVD. Foetal overgrowth can promote the same conditions. Breastfeeding represents a possible strategy to reduce risk of T2DM in both the mother and the child. Conclusions: Ethnic minority women in Europe with Asian and African origin and their offspring seem to be at increased risk of T2DM and CVD, both currently and in the future. Pregnancy is an important window of opportunity for short and long-term disease prevention.

    Full Text Available A two-year old male warty chameleon (Furcifer verrucosus weighing 160 g was presented for veterinary examination following 4 weeks of decreased ability to catch insects with the tongue and difficulty in swallowing the prey. Non-invasive endoscopy did not reveal any macroscopic changes of the oral cavity mucosa or the cranial part of the esophagus. Dorsoventral and laterolateral plain and contrast radiographs revealed enlargement of the medial part of the liver without any visible abnormalities in the regions of the esophagus, stomach or small intestine. Abnormalities in the plasma chemistry profile included transient hyperglycaemia (52.68–57.18 mmol/l and hyperuricaemia (452.70–622.20 μmol/l. The chameleon was examined at 7, 20 and 22 weeks after initial examination. Its body weight decreased to 120 g. A blood profile revealed normoglycaemia (16.37–10.22 mmol/l and hyperphosphataemia (2.92–3.06 mmol/l at the last three examinations. The chameleon died suddenly 33 days after the final examination. Necropsy revealed the presence of a large liver cyst, filled with fluid. The liver had lost all of its normal structure. The kidneys showed a large area with fibrosis and multiple uric acid tophi. The post mortem findings were defined as liver with fatty degeneration and moderate fibrotic changes with large cyst, subchronic nephritis with uric acid tophi, and mineralization in the myocardium. This paper describes the first documented case of transient hyperglycaemia in a warty chameleon (Furcifer verrucosus associated with chronic liver disease and subchronic nephritis.

    To test whether jet injection of insulin resulted in faster correction of marked hyperglycaemia than when insulin is injected by a conventional pen in patients with diabetes. Adult, overweight or obese (BMI ≥25 and ≤40 kg/m(2)) patients with type 1 diabetes (n = 10) or insulin-treated type 2 diabetes (n = 10) were enrolled in a randomized, controlled, crossover study. On two separate occasions, patients were instructed to reduce insulin dose(s) to achieve marked hyperglycaemia (18-23 mmol/l). Subsequently, insulin aspart was administered either by jet injection or by conventional pen, in a dose based on estimated individual insulin sensitivity. Pharmacodynamic and pharmacokinetic profiles were derived from plasma glucose and insulin levels, measured for 6 h after injection. After conventional injection, plasma glucose concentration dropped by ≥10 mmol/l after 192.5 ± 13.6 min. The jet injector advanced this time to 147.9 ± 14.4 min [difference 44.6 (95% confidence interval 4.3, 84.8); P = 0.03], except in 3 patients who failed to reach this endpoint. The time advantage exceeded 1.5 h in patients with a BMI above the median. Jet injection also reduced the hyperglycaemic burden during the first 2 h (2042 ± 37.2 vs 2168 ± 26.1 mmol/min; P = 0.01) and the time to peak insulin levels (40.5 ± 3.2 vs 76.8 ± 7.7 min; P overweight or obese patients with insulin-requiring diabetes. © 2015 John Wiley & Sons Ltd.

    Full Text Available Introduction. Elevated glucose levels on admission in many emergency conditions, including acute myocardial infarction (AMI, have been identified as a predictor of hospital mortality. Objective. Since there are no data in the literature related to stress hyperglycaemia (SH in patients with both AIM and temporary electrical cardiac pacing, we aimed to investigate the influence of stress hyperglycaemia on the prognosis of patients with AMI and temporary electrical cardiac pacing. Methods. The prospective study included 79 patients with diagnosed AMI with ST-segment elevation (STEMI, admitted to the Coronary Care Unit of the Clinic for Cardiovascular Diseases, Clinical Centre Niš, from 2004 to 2007, who were indicated for temporary electrical cardiac pacing. The blood was sampled on admission for lab analysis, glucose levels were determined (as well as markers of myocardial necrosis - troponin I, CK-MB. Echocardiographic study was performed and ejection fraction was evaluated by using area length method. Results. The ROC analysis indicated that the best glycaemic level on admission, which could be used as a predictor of mortality, was 10.00 mmol/l, and the area under the curve was 0.82. In the group without SH, hospital mortality was 3-fold lower 11/48 (22.91% compared to the group with SH 19/31 (61.29%, p<0.0001. Patients with SH were more likely to have higher troponin levels, Killip >1, lower ejection fraction and heart rate, as well as systolic blood pressure. Conclusion. The best cut-off value for SH in patients with AMI (STEMI and temporary electrical cardiac pacing is 10 mmol/l (determined by ROC curve and may be used in risk stratification; patients with glucose levels <10 mmol/l on admission are at 3-fold lower risk compared to those with glucose levels >10 mml/l. Our results suggest that SH is a more reliable marker of poor outcome in AMI patients with temporary pace maker, without previously diagnosed DM.

    'Suioh', a sweet potato (Ipomoea batatas L.) cultivar developed in Japan, has edible leaves and stems. The sweet potato leaves contain polyphenols such as caffeoylquinic acid (CQA) derivatives. It has multiple biological functions and may help to regulate the blood glucose concentration. In this study, we first examined whether sweet potato leaf extract powder (SP) attenuated hyperglycaemia in type 2 diabetic mice. Administration of dietary SP for 5 weeks significantly lowered glycaemia in type 2 diabetic mice. Second, we conducted in vitro experiments, and found that SP and CQA derivatives significantly enhanced glucagon-like peptide-1 (GLP-1) secretion. Third, pre-administration of SP significantly stimulated GLP-1 secretion and was accompanied by enhanced insulin secretion in rats, which resulted in a reduced glycaemic response after glucose injection. These results indicate that oral SP attenuates postprandial hyperglycaemia, possibly through enhancement of GLP-1 secretion.

    Exposure to either environmental toxicants or chronic hyperglycaemia could impair male reproductive function. However, the extent to which exposure to such toxicants, in the presence of pre-existing metabolic dysfunction, could affect male reproduction is unclear. Streptozotocin-induced diabetic Wistar rats (12 weeks old) were exposed to oral aluminium chloride at 250 ppm for 30 days; followed by evaluation of caudal epididymal sperm count and motility, assay for serum follicle stimulating hormone (FSH), testosterone (T) and oestradiol; and assessment of testicular histology. Moreover, blood glucose was evaluated by the glucose oxidase method. In rats treated with streptozotocin (STZ) or aluminium (Al) alone, erosion of testicular parenchyma and stroma was observed. This effect was most severe in diabetic rats simultaneously exposed to Al; coupled with reduced caudal epididymal sperm count that was least in this (STZ+Al) group (18.75 × 10(6)  ml(-1) ) compared with controls (61.25 × 10(6)  ml(-1) ; P < 0.05), STZ group or Al group. Moreover, these reproductive perturbations (in the STZ+Al group) were associated with reduced sperm motility and significantly reduced serum FSH (P < 0.05); but elevated serum T and oestradiol (P < 0.05), compared with control. These suggest that diabetes-induced testicular lesion is exacerbated by simultaneous oral Al toxicity in Wistar rats. © 2015 Blackwell Verlag GmbH.

  5. Long Lasting Microvascular Tone Alteration in Rat Offspring Exposed In Utero to Maternal Hyperglycaemia.

    Directory of Open Access Journals (Sweden)

    Emilie Vessières

    Full Text Available Epidemiologic studies have demonstrated that cardiovascular risk is not only determined by conventional risk factors in adulthood, but also by early life events which may reprogram vascular function. To evaluate the effect of maternal diabetes on fetal programming of vascular tone in offspring and its evolution during adulthood, we investigated vascular reactivity of third order mesenteric arteries from diabetic mother offspring (DMO and control mother offspring (CMO aged 3 and 18 months. In arteries isolated from DMO the relaxation induced by prostacyclin analogues was reduced in both 3- and 18-month old animals although endothelium (acetylcholine-mediated relaxation was reduced in 18-month old DMO only. Endothelium-independent (sodium nitroprusside relaxation was not affected. Pressure-induced myogenic tone, which controls local blood flow, was reduced in 18-month old CMO compared to 3-month old CMO. Interestingly, myogenic tone was maintained at a high level in 18-month old DMO even though agonist-induced vasoconstriction was not altered. These perturbations, in 18-months old DMO rats, were associated with an increased pMLC/MLC, pPKA/PKA ratio and an activated RhoA protein. Thus, we highlighted perturbations in the reactivity of resistance mesenteric arteries in DMO, at as early as 3 months of age, followed by the maintenance of high myogenic tone in older rats. These modifications are in favour of excessive vasoconstrictor tone. These results evidenced a fetal programming of vascular functions of resistance arteries in adult rats exposed in utero to maternal diabetes, which could explain a re-setting of vascular functions and, at least in part, the occurrence of hypertension later in life.

    The aim of this study was to determine the effect of postprandial hyperglycaemia (HG) on the non-invasive measurement of cerebral metabolic rate of glucose (CMRGlc). Five patients who had a meal within an hour before a fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) examination were recruited in this study. They underwent intermittent arterial blood sampling (measured input function), and, based on this sampling, CMRGlc was calculated using an autoradiographic method (CMRGlc{sub real}). Simulated input functions were generated based on standardised input function, body surface area and net injected dose of FDG, and simulated CMRGlc (CMRGlc{sub sim}) was also calculated. Percent error of the area under the curve (AUC) between measured (AUC{sub real}) and simulated input function (AUC{sub IFsim}) and percent error between CMRGlc{sub real} and CMRGlc{sub sim} were calculated. These values were compared with those obtained from a previous study conducted under fasting conditions (F). The serum glucose level in the HG group was significantly higher than that in the F group (165{+-}69 vs 100{+-}9 mg/dl, P=0.0007). Percent errors of AUC and CMRGlc in grey matter and white matter in HG were significantly higher than those in F (12.9%{+-}1.3% vs 3.5%{+-}2.2% in AUC, P=0.0015; 18.2%{+-}2.2% vs 2.9%{+-}1.9% in CMRGlc in grey matter, P=0.0028; 24.0%{+-}4.6% vs 3.4%{+-}2.2% in CMRGlc in white matter, P=0.0028). It is concluded that a non-invasive method of measuring CMRGlc should be applied only in non-diabetic subjects under fasting conditions. (orig.)

    Full Text Available Background. Screening and timely treatment of gestational hyperglycaemia (GH is proved to be beneficial and improves maternal and foetal health outcomes. To understand screening practices, we explored the knowledge and perceptions of doctors working in public health facilities in Bangalore, India. We also studied participation factors by examining whether undergoing glucose estimation tests affects morning sickness in pregnant women. Design and Methods. We aimed to understand the screening practices and knowledge of doctors. A semi-structured questionnaire was self-administered by the 50 participant doctors, selected from the sampling frame comprising of all the doctors working in public health facilities. We included 105 pregnant women for baseline assessment, in whom a well-structured questionnaire was used. Results. We reported that gestational diabetes mellitus (GDM screening was done in nearly all the health centres (96%. However, only 12% of the doctors could provide all components of GDM diagnosis and management correctly and 46% would diagnose by using a random blood glucose test. A majority (92% of the doctors had poor knowledge (68% about the cut-off values of glucose tests. More than 80% of pregnant women experienced some discomfort mostly due to rapid ingestion glucose in short span of time. Conclusions. Our study established that screening for GH is done in most public health facilities. Nonetheless, knowledge of doctors on the glucose tests and their interpretation needs improvement. Re-orientation trainings of the doctors can improve their knowledge and thereby can efficiently screen for GH. Further, adequate planning prior to the tests can aid successful completion of them.

  18. Categorisation of continuous exposure variables revisited. A response to the Hyperglycaemia and Adverse Pregnancy Outcome (HAPO Study

    Henriksen Tore

    2010-11-01

    Full Text Available Abstract Background Although the general statistical advice is to keep continuous exposure variables as continuous in statistical analyses, categorisation is still a common approach in medical research. In a recent paper from the Hyperglycaemia and Adverse Pregnancy Outcome (HAPO Study, categorisation of body mass index (BMI was used when analysing the effect of BMI on adverse pregnancy outcomes. The lowest category, labelled "underweight", was used as the reference category. Methods The present paper gives a summary of reasons for categorisation and methodological drawbacks of this approach. We also discuss the choice of reference category and alternative analyses. We exemplify our arguments by a reanalysis of results from the HAPO paper. Results Categorisation of continuous exposure data results in loss of power and other methodological challenges. An unfortunate choice of reference category can give additional lack of precision and obscure the interpretation of risk estimates. A highlighted odds ratio (OR in the HAPO study is the OR for birth weight >90th percentile for women in the highest compared to the lowest BMI category ("obese class III" versus "underweight". This estimate was OR = 4.55 and OR = 3.52, with two different multiple logistic regression models. When using the "normal weight" category as the reference, our corresponding estimates were OR = 2.03 and OR = 1.62, respectively. Moreover, our choice of reference category also gave narrower confidence intervals. Summary Due to several methodological drawbacks, categorisation should be avoided. Modern statistical analyses should be used to analyse continuous exposure data, and to explore non-linear relations. If continuous data are categorised, special attention must be given to the choice of reference category.

  19. Diabetes in Danish bank voles (M. glareolus): survivorship, influence on weight, and evaluation of polydipsia as a screening tool for hyperglycaemia.

    2011-01-01

    Previous studies have concluded that the development of polydipsia (PD, a daily water intake ≥ 21 ml) among captive Danish bank voles, is associated with the development of a type 1 diabetes (T1D), based on findings of hyperglycaemia, glucosuria, ketonuria/-emia, lipemia, destroyed beta cells, and presence of autoantibodies against GAD65, IA-2, and insulin. We retrospectively analysed data from two separate colonies of Danish bank voles in order to 1) estimate survivorship after onset of PD, 2) evaluate whether the weight of PD voles differed from non-PD voles, and, 3), evaluate a state of PD as a practical and non-invasive tool to screen for voles with a high probability of hypeglycaemia. In addition, we discuss regional differences related to the development of diabetes in Scandinavian bank voles and the relevance of the Ljungan virus as proposed etiological agent. We found that median survival after onset of PD is at least 91 days (lower/upper quartiles = 57/134 days) with a maximum recording of at least 404 days survivorship. The development of PD did not influence the weight of Danish bank voles. The measures of accuracy when using PD as predictor of hyperglycaemia, i.e. sensitivity, specificity, positive predictive value, and negative predictive value, equalled 69%, 97%, 89%, and 89%, respectively. The relatively long survival of Danish PD bank voles suggests potentials for this model in future studies of the long-term complications of diabetes, of which some observations are mentioned. Data also indicates that diabetes in Danish bank is not associated with a higher body weight. Finally, the method of using measurements of daily water intake to screen for voles with a high probability of hyperglycaemia constitutes a considerable refinement when compared to the usual, invasive, methods.

    To investigate the effects of high-polyphenol chocolate upon endothelial function and oxidative stress in Type 2 diabetes mellitus during acute transient hyperglycaemia induced following a 75-g oral glucose challenge. Ten subjects with Type 2 diabetes underwent a double-blinded randomized controlled crossover study. A 75-g oral glucose load was used to induce hyperglycaemia, which was administered to participants 60 min after they had ingested either low (control) or high-polyphenol chocolate. Participants undertook testing at weekly intervals, following an initial cocoa-free period. Endothelial function was assessed by both functional [reactive hyperaemia peripheral artery tonometry (EndoPAT-2000) and serum markers (including intercellular adhesion molecule 1, P-selectin and P-selectin glycoprotein ligand 1]. Urinary 15-F2t-isoprostane adjusted for creatinine was used as an oxidative stress marker. Measurements were made at baseline and 2 h post-ingestion of the glucose load. Prior consumption of high-polyphenol chocolate before a glucose load improved endothelial function (1.7 ± 0.1 vs. 2.3 ± 0.1%, P = 0.01), whereas prior consumption of control chocolate resulted in a significant increase in intercellular adhesion molecule 1 (321.1 ± 7.6 vs. 373.6 ± 10.5 ng/ml, P = 0.04) and 15-F2t-isoprostane (116.8 ± 5.7 vs. 207.1 ± 5.7 mg/mol, P = 0.02). Analysis of percentage changes from baseline comparing control and high-polyphenol chocolate showed a significant improvement for high-polyphenol chocolate in both measures of endothelial function (P chocolate protected against acute hyperglycaemia-induced endothelial dysfunction and oxidative stress in individuals with Type 2 diabetes mellitus. © 2012 The Authors.

    Full Text Available Prolonged heart rate-corrected QT(QTc interval is related to ventricular arrhythmia and cardiovascular mortality, with considerably high prevalence of type 2 diabetes. Additionally, long-term glycaemic variability could be a significant risk factor for diabetic complications in addition to chronic hyperglycaemia. We compared the associations of long-term glycaemic variability versus sustained chronic hyperglycaemia with the QTc interval among type 2 diabetes patients.In this cross-sectional study, 2904 type 2 diabetes patients were recruited who had undergone at least four fasting plasma glucose (FPG and 2-hour postprandial plasma glucose (PPG measurements (at least once for every 3 months, respectively during the preceding year. Long-term glycaemic variabilities of FPG and 2-hour PPG were assessed by their standard deviations (SD-FPG and SD-PPG, respectively, and chronic fasting and postprandial hyperglycaemia were assessed by their means (M-FPG and M-PPG, respectively. HbA1c was also determined upon enrolment to assess current overall glycaemic control. QTc interval was estimated from resting 12-lead electrocardiograms, and more than 440 ms was considered abnormally prolonged.Patients with prolonged QTc interval (≥440 ms had greater M-FPG, M-PPG, SD-PPG and HbA1c than those with normal QTc interval but comparable SD-FPG. QTc interval was correlated with M-FPG, M-PPG, SD-PPG and HbA1c (r = 0.133, 0.153, 0.245 and 0.207, respectively, p = 0.000 but not with SD-FPG (r = 0.024, p = 0.189. After adjusting for metabolic risk factors via multiple linear regression analysis, SD-PPG, M-PPG and HbA1c (t = 12.16, 2.69 and 10.16, respectively, p = 0.000 were the major independent contributors to the increased QTc interval. The proportion of prolonged QTc interval increased significantly from 10.9% to 14.2% to 26.6% for the first (T1 to second (T2 to third (T3 tertiles of SD-PPG. After adjusting via multiple logistic regression analysis, the odd ratios

    Previous studies on isolated islets have demonstrated tight coupling between calcium (Ca(2+)) influx and oxygen consumption rate (OCR) that is correlated with insulin secretion rate (ISR). To explain these observations, we have proposed a mechanism whereby the activation of a highly energetic process (Ca(2+)/metabolic coupling process [CMCP]) by Ca(2+) mediates the stimulation of ISR. The aim of the study was to test whether impairment of the CMCP could play a role in the development of type 2 diabetes. Glucose- and Ca(2+)-mediated changes in OCR and ISR in isolated islets were compared with the time course of changes of plasma insulin concentrations observed during the progression to hyperglycaemia in a rat model of type-2 diabetes (the University of California at Davis type 2 diabetes mellitus [UCD-T2DM] rat). Islets were isolated from UCD-T2DM rats before, 1 week, and 3 weeks after the onset of hyperglycaemia. Glucose stimulation of cytosolic Ca(2+) and OCR was similar for islets harvested before and 1 week after the onset of hyperglycaemia. In contrast, a loss of decrement in islet OCR and ISR in response to Ca(2+) channel blockade coincided with decreased fasting plasma insulin concentrations observed in rats 3 weeks after the onset of hyperglycaemia. These results suggest that phenotypic impairment of diabetic islets in the UCD-T2DM rat is downstream of Ca(2+) influx and involves unregulated stimulation of the CMCP. The continuously elevated levels of CMCP induced by chronic hyperglycaemia in these islets may mediate the loss of islet function.

    Early cardiac surgery may have a trade-off between stabilized hemodynamics with controlled infection and a risk of peri-operative death in patients with infective endocarditis (IE) complicated with cardio-embolic strokes. We retrospectively studied clinical characteristics and outcomes in 68 consecutive patients with IE (mean age, 58±3years, 62% male) who admitted in our institute during June 2013 and August 2015. Cardio-embolic strokes were noted in 37% of patients (n=25) with IE and overall in-hospital mortality was 4 times higher in IE with cardio-embolic strokes than IE with an absence of strokes (n=43) (20% vs. 4.7%, p=0.045). Bacteremia of Staphylococcus aureus (p=0.021) and a complication of cardio-embolic strokes (p=0.031) were independently associated with in-hospital death in those with IE. However, in-hospital mortality was quite low in 19 with early cardiac surgery compared with 6 with conventional treatment in those with cardio-embolic strokes (11% vs. 50%, p=0.035). Multivariate logistic analysis demonstrated that lack of early cardiac surgery (p=0.014), a complication of cerebral hemorrhage (p=0.002), and a presence of refractory heart failure (p=0.047) were independently associated with in-hospital death in those with IE complicated with cardio-embolic strokes. Early cardiac surgery may provide clinical advantages overcoming peri-operative risks in those with IE complicated with cardio-embolic strokes. Copyright © 2016 Elsevier Ireland Ltd.

    We assessed patient outcomes 90 days after hospital admission for stroke following a multidisciplinary intervention targeting evidence-based management of fever, hyperglycaemia, and swallowing dysfunction in acute stroke units (ASUs). In the Quality in Acute Stroke Care (QASC) study, a single-blind cluster randomised controlled trial, we randomised ASUs (clusters) in New South Wales, Australia, with immediate access to CT and on-site high dependency units, to intervention or control group. Patients were eligible if they spoke English, were aged 18 years or older, had had an ischaemic stroke or intracerebral haemorrhage, and presented within 48 h of onset of symptoms. Intervention ASUs received treatment protocols to manage fever, hyperglycaemia, and swallowing dysfunction with multidisciplinary team building workshops to address implementation barriers. Control ASUs received only an abridged version of existing guidelines. We recruited pre-intervention and post-intervention patient cohorts to compare 90-day death or dependency (modified Rankin scale [mRS] ≥2), functional dependency (Barthel index), and SF-36 physical and mental component summary scores. Research assistants, the statistician, and patients were masked to trial groups. All analyses were done by intention to treat. This trial is registered at the Australia New Zealand Clinical Trial Registry (ANZCTR), number ACTRN12608000563369. 19 ASUs were randomly assigned to intervention (n=10) or control (n=9). Of 6564 assessed for eligibility, 1696 patients' data were obtained (687 pre-intervention; 1009 post-intervention). Results showed that, irrespective of stroke severity, intervention ASU patients were significantly less likely to be dead or dependent (mRS ≥2) at 90 days than control ASU patients (236 [42%] of 558 patients in the intervention group vs 259 [58%] of 449 in the control group, p=0·002; number needed to treat 6·4; adjusted absolute difference 15·7% [95% CI 5·8-25·4]).

    Recently, we reported that [meso-tetrakis(4-sulfonatophenyl)porphyrinato]oxovanadium(IV)(4-), VO(tpps), shows in-vitro insulin-mimetic and in-vivo anti-diabetic activity in streptozotocin (STZ)-induced type 1 diabetic mice. This result prompted us to examine its ability in type 2 diabetic model KKA(y) mice with insulin resistance. We studied the in-vivo anti-diabetic activity of VO(tpps), compared with that of vanadium(IV) oxide sulfate, VS, as control. Both compounds were orally administered at doses of 5-10 mg (0.1-0.2 mmol) V/kg body weight to the KKA(y) mice for 28 days. VO(tpps) normalized the hyperglycaemia within 15 days, while VS lowered the blood glucose concentration only by a small degree. In addition, metabolic syndromes characterized by insulin and leptin resistance were significantly improved in VO(tpps)-treated KKA(y) mice compared with those treated with VS. The improvement in diabetes was validated by oral glucose tolerance test and decrease in HbA(1c) concentration. Based on these observations, VO(tpps) is proposed to be an orally active oxovanadium(IV)-porphyrin complex for treating not only type 2 diabetes but also metabolic syndromes in animals.

    Biochemical analysis of glucose and ketones in the vitreous humour obtained at post-mortem examination is representative of the levels in the blood prior to death. Elevated levels can be indicative of conditions including diabetic ketoacidosis, which can be a cause for unexpected death. A rapid screening test for such conditions can be performed during the autopsy through urinalysis using test strips (urine 'dipstick' testing). The aim of this study was to assess the utility of urinalysis testing for post-mortem detection of derangements of glucose and ketone levels. The results of vitreous biochemical analysis and urinalysis were collated from 188 forensic autopsy cases. A vitreous glucose result of above 10 mmol/L was regarded as high. When this was compared to urinalysis results it was found that any urinalysis result above negative had a sensitivity of 0.83 and a specificity of 0.93. A vitreous ketone level of above 5 mmol/L was regarded as significantly elevated; a urinalysis result above negative had a sensitivity of 1, but a specificity of 0.12. Urinalysis ('dipstick' testing) for glucose has a good sensitivity and specificity for high vitreous glucose levels, which are regarded as indicative of pathological hyperglycaemia during life. It was found that urine testing for ketones either has an excellent sensitivity with low specificity or a poor sensitivity with a good specificity; however, this finding has to be viewed in the context of uncertainty of the biochemical level of significant ketosis.

    GdCl3 (gadolinium chloride) has been shown to reduce blood glucose; however, the underlying mechanism remains unclear. Liver gluconeogenesis is an important pathway involved in the maintenance of glucose homoeostasis. The aim of the present study was to investigate the role of GdCl3 in hepatic gluconeogenesis and explore the precise molecular mechanism. Animals from a classical Type 2 diabetic mouse model, created by exposing C57BL/6J mice to a high-fat diet for 4 months, were treated with GdCl3 or saline. Body weight, blood glucose and insulin sensitivity were monitored. It was observed that GdCl3 significantly reduced blood glucose levels and improved insulin sensitivity. A pyruvate tolerance test showed further that GdCl3 suppressed gluconeogenesis in diabetic mice. In the livers of GdCl3-treated mice, the expression of Pepck (phosphoenolpyruvate carboxykinase) and G6pase (glucose-6-phosphatase), the key enzymes in gluconeogenesis, were dramatically reduced. Furthermore, experiments in hepatocarcinoma cells revealed that GdCl3 activated the Akt pathway to promote the phosphorylation of FoxO1 (forkhead box O1), leading to the suppression of gluconeogenesis by reducing the expression of PEPCK and G6Pase and resulting in decreased cellular production of glucose. Comparable results were observed in the livers of GdCl3-treated mice. In addition, we have shown that GdCl3 augmented the role of insulin to control hepatic glucose production. We conclude that GdCl3 reduces hyperglycaemia via the Akt/FoxO1-induced suppression of hepatic gluconeogenesis, both in Type 2 diabetic mice (in vivo) and in hepatocarcinoma cells (in vitro), suggesting that GdCl3 may be a potential therapeutic agent for diabetes.

    Full Text Available Introduction: Despite the major improvements in surgical technique and perioperative care, radical cystectomy (RC remains a major operative procedure with a significant morbidity and mortality. The present study analyzes the early complications of RC and urinary diversion using a standardized reporting system. Materials and Methods: Modified Clavien-Dindo classification was used to retrospectively assess the peri-operative course of 212 patients who had RC with urinary diversion between October 2003 and October 2014 at a single institution. The indications for surgery were muscle invasive urothelial carcinoma, high-grade nonmuscle invasive bladder cancer (BC, and Bacillus Calmette-Guerin-resistant nonmuscle invasive BCs. Data on age, sex, comorbidities, smoking history, American Society of Anaesthesiologists score, and peri-operative complications (up to 90 days were captured. Statistical analysis was performed using SPSS 20.0 software (Chicago, USA. Results: The mean age was 56.15 ΁ 10.82. Orthotopic neobladder was created in 113 patients, ileal conduit in 88 patients, and cutaneous ureterostomy in 11 patients. A total of 292 complications were recorded in 136/212 patients. 242 complications (81.16% occurred in the first 30 days, with the remaining 50 complications (18.83% occurring thereafter. The rates for overall complication were 64.1%. The most common complications were hematologic (21.6%. Most of the complications were of Grade I and II (22.9% and 48.9%, respectively. Grade IIIa, IIIb, IVa, IVb, and V complications were observed in 10.2%, 8.9%, 3.4%, 2.7%, and 2.7% of the patients, respectively. Conclusions: RC and urinary diversion are associated with significant morbidity. This audit would help in setting a benchmark for further improvement in the outcome.

    The assessment of new therapies in the adjuvant setting in early breast cancer requires large numbers of patients and many years of follow-up for results to be presented. Therefore, the neoadjuvant study setting, which allows for early prediction of treatment response in smaller patient sets, has become increasingly popular. Ki67 is the most commonly used and extensively studied intermediate biomarker of treatment activity and residual risk in neoadjuvant trials on endocrine therapy, new biological therapies, and chemotherapy. It is increasingly being used as a primary endpoint for new therapies particularly those added to endocrine therapy. The PeriOperative Endocrine Therapy for Individualizing Care (POETIC) trial, including more than 4000 postmenopausal, estrogen receptor (ER)-positive patients randomly assigned to receive 2 weeks of presurgical treatment with an aromatase inhibitor or no further treatment, is the largest window-of-opportunity trial conducted and is assessing the clinical utility of on-treatment Ki67 as a predictor of long-term outcome. For generalizability, Ki67 measurements in the POETIC and other trials need to use standard methodology. The International Working Group on Ki67 in Breast Cancer is conducting a series of studies to bring this to reality. © The Author 2015. Published by Oxford University Press. All rights reserved.

    Full Text Available Awareness of the presence of thyroid function abnormalities in patients with molar pregnancy is important for its prompt diagnosis and management. We report the development of thyroid storm in the immediate post-operative period in a 25-year-old female who underwent evacuation of her molar pregnancy under saddle spinal block after being controlled for her thyrotoxicosis with a combination of antithyroid drugs, iodine, steroids and adrenergic blocking agents. We advocate the use of esmolol infusions up to a maximum dose of 200 μg/kg/min for immediate haemodynamic management of the patient. Optimum time needed for stabilisation of the hyper metabolic state after initiation of antithyroid drugs is still not known and evacuation of molar pregnancy remains the only definitive management of the thyrotoxic state.

    2006-12-01

    Knee osteoarthritis (OA) is often associated with pain, functional impairment and various degrees of disability. Physiotherapy in combination with both aerobic and strength training exercises have shown positive effects in both the pre-operative and post-operative period. At the initial stages of osteoarthritis, physical therapy and education can improve the functional outcome and the participation of patients in daily activities. In the case of OA progression and when an operation is the only effective treatment, physiotherapy is very useful in enhancing self-esteem and minimising depression and anxiety for the forthcoming surgery. Post-operative intense physical therapy and Continuous Passive Motion (CPM) application offer remarkable benefits in terms of faster recovery, shorter hospital stay and increase of range of motion. Furthermore, home-based excercises following discharge from the hospital should be encouraged in order to optimise the final result. Although the entire mechanism remains unclear, physical exercise protocols may be beneficial for patients and the health system alike.

    Full Text Available Plasma is used to correct coagulopathies, but not all coagulation abnormalities are clinically significant enough to require correction before an invasive procedure. We report an 82-year-old female who, in response to a mildly prolonged INR of unknown etiology, was unnecessarily transfused with plasma in advance of elective surgery. The patient suffered a moderately severe transfusion reaction, including hives and voice hoarseness, which caused a 4-week delay in her surgery. This delay and adverse reaction could have been avoided had the principles of evidence based plasma therapy, which we herein review, been followed and if the etiology of the mildly elevated INR been investigated before the day of her surgery.

    Abstract Background To examine the blood glucose profile and the relationship between blood glucose levels and neurodevelopmental outcome in term infants with hypoxic-ischaemic encephalopathy. Methods Blood glucose values within 72 hours of birth were collected from 52 term infants with hypoxic-ischaemic encephalopathy. Hypoglycaemia [< 46.8 mg\\/dL (2.6 mmol\\/L)] and hyperglycaemia [> 150 mg\\/dL (8.3 mmol\\/L)] were correlated to neurodevelopmental outcome at 24 months of age. Results Four fifths of the 468 blood samples were in the normoglycaemic range (392\\/468:83.8%). Of the remaining 76 samples, 51.3% were in the hypoglycaemic range and (48.7%) were hyperglycaemic. A quarter of the hypoglycaemic samples (28.2%:11\\/39) and a third of the hyperglycaemic samples (32.4%:12\\/37) were recorded within the first 30 minutes of life. Mean (SD) blood glucose values did not differ between infants with normal and abnormal outcomes [4.89(2.28) mmol\\/L and 5.02(2.35) mmol\\/L, p value = 0.15] respectively. In term infants with hypoxic-ischaemic encephalopathy, early hypoglycaemia (between 0-6 hours of life) was associated with adverse outcome at 24 months of age [OR = 5.8, CI = 1.04-32)]. On multivariate analysis to adjust for grade of HIE this association was not statistically significant. Late hypoglycaemia (6-72 hours of life) was not associated with abnormal outcome [OR = 0.22, CI (0.04-1.14)]. The occurrence of hyperglycaemia was not associated with adverse outcome. Conclusion During the first 72 hours of life, blood glucose profile in infants with hypoxic-ischaemic encephalopathy varies widely despite a management protocol. Early hypoglycaemia (0-6 hours of life) was associated with severe HIE, and thereby; adverse outcome.

    To identify the impact of the presence of patent foramen ovale (PFO) in patients undergoing liver transplantation. Twenty-seven pre-liver transplant patients who had a PFO (PFO group) were identified and compared with 61 patients without PFO (NoPFO group). Patients were matched according to age, gender and cause of liver disease. The diagnosis of PFO was made by transthoracic echocardiography prior to liver transplantation. Patient baseline characteristics and complications during the early post-transplant period were analyzed. The mean age in the PFO group was 47 ± 14 (range 18-68) yr and 50 ± 11 (range 12-65) yr in the NoPFO group. The PFO group had a mean model for end-stage liver disease (MELD) score of 15 ± 10 whereas in the NoPFO group the MELD score was 19 ± 10 (p = 0.08). There were non-significant differences in echocardiographic parameters between groups. Duration of mechanical ventilation and the incidence of neurological complications were similar. Thirty-day mortality rate was similar in both groups; only one patient in the NoPFO group died within the first 30 days post-transplantation. The presence of PFO in patients with end-stage liver disease undergoing liver transplantation does not appear to affect patient outcomes during the peri-operative period. © 2010 John Wiley & Sons A/S.

    To explore whether the prevalence and severity of retinopathy differ in diabetes cohorts diagnosed through screening as compared with conventional health care. A total of 257 diabetes patients, 151 detected through screening and 106 through conventional clinical care, were included. Retinopathy was evaluated by fundus photography. The modified Airlie House adaptation of the Early Treatment Retinopathy Study protocol was used to grade the photographs. Averages of clinically collected fasting blood glucose (FBG), blood pressure and body mass index values were compiled from diabetes diagnosis until the eye examination. Blood chemistry, smoking habits and peripheral neuropathy were assessed at the time of the eye examination. Among the screening-detected patients, 22% had retinopathy as compared to 51% among those clinically detected (p retinopathy were more likely to have increased average FBG (OR 1.42, 95% CI 1.19-1.70 per mmol/l) and peripheral neuropathy (OR 2.75, 95% CI 1.40-5.43), but less likely to have screening-detected diabetes (OR 0.31, 95% CI 0.17-0.57). Similar results were found using increasing severity grade of retinopathy as outcome. The cumulative retinopathy prevalence for the screening-detected diabetes cohort as compared with the clinically diagnosed cohort was significantly lower from 10 years' follow-up and onwards (p = 0.0002). Among patients with screening-detected diabetes, the prevalence of retinopathy and increasing severity of retinopathy were significantly lower than among those who had their diabetes diagnosed through conventional care, even when other risk factors for retinopathy such as duration, hyperglycaemia and blood pressure were considered. Early detection of diabetes reduces prediagnostic time spent with hyperglycaemia. In combination with early and regular screening for retinopathy, more effective prevention against retinopathy can be provided. © 2016 Acta Ophthalmologica Scandinavica Foundation.

    Full Text Available Poor fetal growth, also known as intrauterine growth restriction (IUGR, is a worldwide health concern. IUGR is commonly associated with both an increased risk in perinatal mortality and a higher prevalence of developing chronic metabolic diseases later in life. Obesity, type 2 diabetes or metabolic syndrome could result from noxious "metabolic programming." In order to better understand early alterations involved in metabolic programming, we modeled IUGR rat pups through either prenatal exposure to synthetic glucocorticoid (dams infused with dexamethasone 100 µg/kg/day, DEX or prenatal undernutrition (dams feeding restricted to 30% of ad libitum intake, UN. Physiological (glucose and insulin tolerance, morphometric (automated tissue image analysis and transcriptomic (quantitative PCR approaches were combined during early life of these IUGR pups with a special focus on their endocrine pancreas and adipose tissue development. In the absence of catch-up growth before weaning, DEX and UN IUGR pups both presented basal hyperglycaemia, decreased glucose tolerance, and pancreatic islet atrophy. Other early metabolic defects were model-specific: DEX pups presented decreased insulin sensitivity whereas UN pups exhibited lowered glucose-induced insulin secretion and more marked alterations in gene expression of pancreatic islet and adipose tissue development regulators. In conclusion, these results show that before any catch-up growth, IUGR rats present early physiologic, morphologic and transcriptomic defects, which can be considered as initial mechanistic basis of metabolic programming.

    Optimal surgical management of older adults with cancer starts pre-operatively. The surgeon plays a key role in the appropriate selection of patients and procedures, optimisation of their functional status prior to surgery, and provision of more intensive care for those who are at high risk of post-operative complications. The literature, mainly based on retrospective, non-randomised studies, suggests that factors such as age, co-morbidities, pre-operative cognitive function and intensity of the surgical procedure all appear to contribute to the development of post-operative complications. Several studies have shown that a pre-operative geriatric assessment predicts post-operative mortality and morbidity as well as survival in older surgical cancer patients. Geriatricians are used to working in multidisciplinary teams that assess older patients and make individual treatment plans. However, the role of the geriatrician in the surgical oncology setting is not well established. A geriatrician could be a valuable contribution to the treatment team both in the pre-operative stage (patient assessment and pre-operative optimisation) and the post-operative stage (patient assessment and treatment of medical complications as well as discharge planning).

    To evaluate the results of the introduction of new measures to accelerate the postoperative recovery of patients undergoing elective abdominal surgery. We observed 162 patients and interviewed them on two distinct periods: the first between October to December 2009 (n = 81) comprised patients who underwent conventional perioperative monitoring (pre-intervention) and the second between March and May 2010 (n = 81), formed by a new group of patients, submitted to the new protocol of perioperative monitoring. Data collection in the two periods occurred without the knowledge of the professionals in the service. The variables were: indication for preoperative nutritional support, duration of fasting, post-operative volume of hydration, use of catheters and drains, length of stay and postoperative morbidity. when comparing the two periods we observed a decrease of 2.5 hours in the time of preoperative fasting (p = 0.0002) in the post-intervention group. As for the reintroduction of oral diet, there was no difference between the two periods (p = 0.0007). When considering the patients without postoperative complications, there was a significantly decreased length of stay (p = 0.001325). There was a reduction of approximately 50% in antibiotic use in the post-intervention group (p = 0.00001). The adoption of multidisciplinary perioperative measures is feasible within our reality, and although there was no statistically significant changes in the present study, it may improve morbidity and reduce length of stay in general surgery.

    Provision of appropriate analgesia for supraumbilical pyloromyotomy in infants is limited by concerns about sensitivity to opioids and other medication groups, due to immature metabolism. Local anesthetic infiltration and ultrasound guided rectus sheath blockade are two techniques commonly employed to provide perioperative analgesia. The aim of this review was to compare the quality of post-operative analgesia afforded by these two techniques. A retrospective chart analysis of hospital records of all patients who underwent supraumbilical pyloromyotomy at a tertiary pediatric hospital between March 2009 and February 2011. Analysis of the anesthetic technique employed and post-operative acetaminophen requirements were performed. Additional information as to time to first post-operative feed, any complications and time of discharge from the hospital were collected by reviewing the post-operative nursing notes. A total of 30 patients underwent supraumbilical pyloromyotomy during this period. A total of 18 received local anesthetic infiltration at the end of the procedure and 12 patients underwent ultrasound guided pre-incisional rectus sheath block for post-operative analgesia. Patients who had post-operative local anesthetic infiltration had a median (range) of 2 (1-3) doses of acetaminophen in the first 24 h. In the group of patients who received a rectus sheath block, the median (range) number of doses of acetaminophen in the first 24 h was also 2 (1-3). There were no differences in time to first feed and time to hospital discharge between the groups. The volume of local anesthetic administered was significantly smaller in the group receiving analgesia via rectus sheath block. Local anesthetic infiltration and pre-incisional ultrasound guided rectus sheath block provide similar degrees of post-operative analgesia. There were no differences between the two groups in time for first post-operative feed and time to hospital discharge.

    Maximal surgical resection of high grade brain tumours is associated with improved overall survival (OS). It carries the risk of neurological deterioration leading to worsening performance status (PS), which may affect overall survival and preclude patients from adjuvant therapy. We aim to review the changes in performance status of patients undergoing resection of high grade tumours and metastases and the impact of changes on overall survival. A prospective study of the perioperative performance status of 75 patients who underwent primary resection of malignant primary brain tumour or solitary metastasis in a single centre. Data on patients' demographics, tumour histology and overall survival were also collected. WHO performance status was recorded pre-operatively and at intervals following surgery. Of the 75 patients (35 males, 40 females, median age 61 years at diagnosis), 50 had primary malignant brain tumours, 25 had metastasis. Although PS dropped at postoperative day 1 in 14 patients (18.7%), 28% improved by day 5 and there was significant improvement by day 14 (41%, p=0.02). The number of patients with PS 3 or worse changed from 4% pre-operatively (n=3) to 8% (n=6). Overall survival is better in those whose PS remained improved or unchanged at 2 weeks after surgery compared to those whose PS deteriorated; high grade glioma median survival 15.67 vs. 2.4 months (p=0.005) and metastasis median survival 8.53 vs.2.33 months (p=0.001). Our data demonstrates that although PS may deteriorate immediately after surgery, the majority of patients regain their baseline PS or improve by 2 weeks postoperatively; decisions on fitness for adjuvant treatment should therefore be delayed until then. In those patients whose PS declines following surgery overall survival is poor. Crown Copyright © 2017. Published by Elsevier B.V. All rights reserved.

    Luke T Lavallée

    Full Text Available OBJECTIVE: To characterize the frequency and timing of complications following radical cystectomy in a cohort of patients treated at community and academic hospitals. PATIENTS AND METHODS: Radical cystectomy patients captured from NSQIP hospitals from January 1 2006 to December 31 2012 were included. Baseline information and complications were abstracted by study surgical clinical reviewers through a validated process of medical record review and direct patient contact. We determined the incidence and timing of each complication and calculated their associations with patient and operative characteristics. RESULTS: 2303 radical cystectomy patients met inclusion criteria. 1115 (48% patients were over 70 years old and 1819 (79% were male. Median hospital stay was 8 days (IQR 7-13 days. 1273 (55.3% patients experienced at least 1 post-operative complication of which 191 (15.6% occurred after hospital discharge. The most common complication was blood transfusion (n = 875; 38.0%, followed by infectious complications with 218 (9.5% urinary tract infections, 193 (8.4% surgical site infections, and 223 (9.7% sepsis events. 73 (3.2% patients had fascial dehiscence, 82 (4.0% developed a deep vein thrombosis, and 67 (2.9% died. Factors independently associated with the occurrence of any post-operative complication included: age, female gender, ASA class, pre-operative sepsis, COPD, low serum albumin concentration, pre-operative radiotherapy, pre-operative transfusion >4 units, and operative time >6 hours (all p<0.05. CONCLUSION: Complications remain common following radical cystectomy and a considerable proportion occur after discharge from hospital. This study identifies risk factors for complications and quality improvement needs.

    Surgical site infections (SSIs) are the leading cause of hospital-acquired infections and are associated with substantial healthcare costs, with increased morbidity and mortality. To investigate the effects of the antibiotic stewardship program on prevention and control of SSI during clean surgery, we investigated this situation in our institution. We performed a quasi-experimental study to compare the effect before and after the antibiotic stewardship program intervention. During the pre-intervention stage (January 1, 2010 through December 31, 2011), comprehensive surveillance was performed to determine the SSI baseline data. In the second stage (January 1, 2012 through December 31, 2016), an infectious diseases physician and an infection control practitioner identified the surgical patients daily and followed up on the duration of antimicrobial prophylaxis. From January 1, 2010 to December 31, 2016, 41,426 patients underwent clean surgeries in a grade III, class A hospital. The rate of prophylactic antibiotic use in the 41,426 clean surgeries was reduced from 82.9% to 28.0% after the interventions. The rate of antibiotic agents administered within 120 minutes of the first incision increased from 20.8% to 85.1%. The rate at which prophylactic antimicrobial agents were discontinued in the first 24 hours after surgery increased from 22.1% to 60.4%. Appropriate antibiotic selection increased from 37.0% to 93.6%. Prophylactic antibiotic re-dosing increased from 3.8% to 64.8%. The SSI rate decreased from 0.7% to 0.5% (p < 0.05). The pathogen detection rate increased from 16.7% up to 41.8% after intervention. The intensity of antibiotic consumption reduced from 74.9 defined daily doses (DDDs) per 100 bed-days to 34.2 DDDs per 100 bed-days after the interventions. Long-term and continuous antibiotic stewardship programs have important effects on the prevention and control of SSI during clean surgery.

    A bone-anchored hearing aid uses the principle of bone conduction and osseointegration to transfer sound vibrations to a functioning inner ear. It consists of a permanent titanium implant, and removable abutment and sound processor. Informed consent requires discussion of the procedural benefits, alternatives and complications. The risks of bone-anchored hearing aid surgery include infection, soft tissue hypertrophy, skin graft or flap failure, osseointegration failure, and the need for further surgery. A case of cerebrospinal fluid leak in a patient undergoing bone-anchored hearing aid surgery is reported and discussed. Bone-anchored hearing aid surgery poses a risk of breaching the inner table of the temporal bone and dura, resulting in a cerebrospinal fluid leak; the risk of meningitis is rare but serious. The surgeon should discuss the possibility of cerebrospinal fluid leak when consenting patients. Pre-operative computerised tomography scanning should be considered in certain individuals to aid implant placement.

    To see the early post-operative outcomes of off-pump versus on-pump coronary artery bypass graft surgery. This retrospective analytical study was conducted at Ch. Pervaiz Elahi Institute of Cardiology Multan, Pakistan. Our Primary outcome variables were; necessity of inotropic support, nonfatal myocardial infarction, ICU stay, nonfatal stroke, new renal failure requiring dialysis and death within 30 days after operation. There were two groups of patients; Group-I (On-pump group) and Group-II (Off-pump Group). SPSS V17 was used for data analysis. Independent sample t-test and Mann Whitney U test were used to compare quantitative Variables. Chi-square test and Fisher's exact test were used to analyze qualitative variables. P-value ≤ 0.05 was considered significant. Three hundred patients were included in this study. There were no significant difference regarding risk factors except hyper-cholestrolemia which was high in off pump group (p-value 0.05). Angiographic and Echocardiographic characteristics e.g. preoperative ejection fraction, LV function grade and severity of CAD was same between the groups. Mortality risk scores and Priority status for surgery were also same. Regarding post-operative outcomes; Post-op CKMB Levels, need and duration of inotropic support, mechanical ventilation time and ICU stay was significantly less in Off-Pump group (p-value 0.001, pump CABG group (p-value 0.027). Incidence of post-op complications was not statistically different between the groups. At 30 days follow-up, Incidence of myocardial infarction, necessity and duration of inotropic support, ICU stay period and peri-operative bleeding were significantly less in off-pump group. The incidence of neurologic, pulmonary and renal complications was same between the off-pump and on-pump groups.

    The last two decades have seen significant changes in surgical management of breast cancer. The offer of immediate breast reconstruction (IBR) following mastectomy is currently standard practice. Skin sparing and nipple sparing mastectomy with implant-based IBR have emerged as oncologically safe treatment options. Prepectoral implant placement and complete coverage of implant with acellular dermal matrix (ADM) eliminates the need to detach the muscle from underlying chest wall in contrast to the subpectoral technique. We report short-term outcomes of a multicentre study from the United Kingdom (UK) using Braxon ® in women having an IBR. A prospective study was conducted from December 2015 to October 2016 and included all patients from three breast units in the UK who underwent a mastectomy and an implant-based IBR using Braxon ® . The demographic details, co-morbidities, operative details, immediate and delayed complications were recorded. Specific complications recorded were infection, seroma, unplanned readmission and loss of implant. A comparison was made with complications reported in the National Mastectomy and Reconstruction Audit. Seventy-eight IBRs were included in the analysis with a median follow-up of 9.98 months. Mean age of the cohort was 50 years with a mean body mass index of 25.7 kg/m 2 . Mean implant volume was 365 cc. The inpatient hospital stay was 1.48 days. About 23% of patients had a seroma, 30% had erythema requiring antibiotics and the explant rate was 10.2 percent. Bilateral reconstructions were significantly associated with implant loss and peri-operative complications on univariate analysis. Our early experience with this novel prepectoral technique using Braxon ® has shown it to be an effective technique with complication rates comparable to subpectoral IBR. The advantages of prepectoral implant-based IBR are quicker postoperative recovery and short post-operative hospital stay. Long-term studies are required to assess rippling, post

The need for a better understanding of the processes, including physician-specific mechanisms, is apparent. The aim of this study was to analyse the association between general practitioners' prescribing....... There was a positive association between the prevalence of prescribing for the specific drugs studied (antidepressants, antidiabetics, drugs against osteoporosis and lipid-lowering drugs) and early discontinuation (r = 0.29 -0.44), but not for anti-hypertensive drugs. The analysis of the association between prevalence...... of all drugs and drug-specific early discontinuation showed some degree of positive association - strongest for anti-hypertensive drugs (r = 0.62) and antidepressants (r = 0.43). Conclusion This study confirmed our hypothesis that general practitioners with high levels of prescribing attain higher rates...

    The appropriateness of lobectomy for all elderly patients is controversial. Meanwhile, sublobar resection is associated with reduced operative risk, better preservation of pulmonary function, and a better quality of life, constituting a potential alternative to standard lobectomy for elderly patients with early-stage non-small cell lung cancer (NSCLC). To date, no randomized trial comparing sublobar resection and lobectomy focusing on elderly patients has been reported. We hypothesized that for patients at least 70 years old with clinical stage T1N0M0 NSCLC, sublobar resection is non-inferior to lobectomy for 3-year disease-free survival (DFS). This is a prospective, randomized, controlled multicenter non-inferiority trial with two study arms: sublobar resection and lobectomy groups. Comprehensive geriatric assessments will be acquired for each patient. A total of 339 subjects will be enrolled on the basis of power calculations, and participants followed up every 6 months post-operation for 3 years. In case of relapse, survival follow-up will be continued until 5 years or death. Pulmonary function testing will be performed at 6, 12, and 36 months post-operation. The primary outcome is 3-year DFS; secondary endpoints include peri-operative complications and mortality, hospitalization time, post-operative ventilator time, overall survival, 3-year recurrence rates, post-operative pulmonary function, quality of life, geriatric assessment data, and 4-year mortality index. The present study is the only prospective, multicenter, randomized controlled trial comparing sublobar resection and lobectomy for elderly patients. The therapeutic outcomes of sublobar resection will be evaluated in comparison with lobectomy for elderly patients (≥70 years) with early-stage NSCLC. NCT02360761 : 01/24/2015 (ClinicalTrials.gov).

    Full Text Available Objective To probe into the early effect of surgical treatment in coronary atherosclerotic heart disease (CAD patients with moderate-to-severe ischemic mitral regurgitation (IMR. Methods A total of 175 CAD patients with moderateto- severe IMR undergoing coronary artery bypass grafting (CABG from December 1999 to December 2010 were analyzed retrospectively. Based on the method applied during surgery, 108 patients were assigned to CABG group, undergoing CABG alone, and 67 to CABG+MVP/R group, undergoing CABG plus concomitant mitral valvuloplasty/repair (MVP/R. Differences between groups were compared in age, gender, numbers of the conduits, application of intra-aortic balloon pump (IABP and ventricular assist device (VAD, perioperative mortality, and other concomitant procedures (i.e. aortic valve replacement, resection of the heart wall aneurysm, repair of the septal defect repair. Differences within the groups were looked for in terms of left atrial diameter (LA, left ventricular ending diastolic diameter (LVEDD, left ventricular ejection fraction (LVEF, mitral regurgitation degree, systolic pulmonary artery pressure (sPAP, and cardiac function (NYHA classification, pre-operatively and post-operatively. Results  The differences between the groups showed no statistical significance in terms of age, gender, numbers of conduits, application of IABP and VAD, peri-operative mortality, and concomitant procedures (P > 0.05. LA, LVEDD, mitral regurgitation, sPAP, and cardiac function (NYHA classification after operation were improved obviously in both groups compared with that before operation (P 0.05. Conclusions The comprehensive and aggressive surgery did not result in more ideal early effect to CAD patients with moderate-to-severe IMR. Based on the total revascularization, we can choose simpler, safer, and more effective surgical methods.

  5. Moderately early (7-14 days) postnatal corticosteroids for preventing chronic lung disease in preterm infants.

    Corticosteroids have been used late in the neonatal period to treat chronic lung disease (CLD) in preterm babies, and early to try to prevent it. CLD is likely to be the result of persisting inflammation in the lung and the use of powerful anti-inflammatory drugs like dexamethasone has some rationale. Early use tends to be associated with increased adverse effects so that studies of moderately early treatment (7-14 days postnatal) might have the dual benefits of fewer side effects and onset of action before chronic inflammation is established. To determine if moderately early (7-14 days) postnatal corticosteroid treatment vs control (placebo or nothing) is of benefit in the prevention and/or treatment of early chronic lung disease in the preterm infant. Randomised controlled trials of postnatal corticosteroid therapy were sought from the Oxford Database of Perinatal Trials, Cochrane Database of Controlled Trials, MEDLINE (1966 - October 2002), hand searching paediatric and perinatal journals, examining previous review articles and information received from practicing neonatologists. Authors of all studies were contacted, where possible, to confirm details of reported follow-up studies, or to obtain any information about long-term follow-up where none had been reported. Randomised controlled trials of postnatal corticosteroid treatment from 7-14 days of birth in high risk preterm infants were selected for this review. Data regarding clinical outcomes including mortality, CLD (including late rescue with corticosteroids, or need for home oxygen therapy), death or CLD, failure to extubate, complications during the primary hospitalisation (including infection, hyperglycaemia, hypertension, hypertrophic cardiomyopathy, pneumothorax, severe intraventricular haemorrhage (IVH), necrotizing enterocolitis (NEC), gastrointestinal bleeding, and severe retinopathy of prematurity (ROP)), and long term outcome (including blindness, deafness, cerebral palsy and major neurosensory

    This paper examines age patterns of first marriage and motherhood and covariates of early marriage, delayed consummation of marriage and early motherhood in Nepal using data from the 2000 Nepal Adolescent and Young Adult Survey (NAYA). Both unmarried and married male and female youths (age 14-22) were included in the survey. The analysis is based on 2800 urban youths and 5075 rural youths with complete information on the variables examined. Proportional hazard models are used to estimate covariates of early marriage and early motherhood, and logistic regression models are used to estimate covariates of delayed consummation of marriage. The results show that early marriage and early motherhood are quite common among Nepalese women, especially in rural areas. Early marriage is much less common among men. Delayed consummation of marriage is common among very young brides, especially in rural areas. The main covariates associated with early marriage and early motherhood are respondent's education, region of residence and ethnicity. The main covariates of delayed consummation of marriage are age at first marriage, region of residence and ethnicity. The study highlights the need to focus on less educated female youths in the Terai region in order to reduce the reproductive and child health risks associated with early marriage and early childbearing.

    To evaluate the association between time of postpartum discharge and symptoms indicative of complications during the first postpartum week. Women with vaginal delivery at a Mexico City public hospital, without complications before the hospital discharge, were interviewed seven days after delivery. Time of postpartum discharge was classified as early (25 hours). The dependent variable was defined as the occurrence and severity of puerperal complication symptoms. Out of 303 women, 208 (68%) were discharged early. However, women with early discharge and satisfactory prenatal care had lower odds of presenting symptoms in early puerperium than women without early discharge and inadequate prenatal care (OR 0.36; 95% confidence intervals = 0.17-0.76). There was no association between early discharge and symptoms of complications during the first postpartum week; the odds of complications were lower for mothers with early discharge and satisfactory prenatal care.

    This 7 year NIHR programme [2011-2018] tests the primary hypothesis that the NDPS diet and physical activity intervention will reduce the risk of transition to type 2 diabetes (T2DM) in groups at high risk of Type 2 diabetes. The NDPS programme recognizes the need to reduce intervention costs through group delivery and the use of lay mentors with T2DM, the realities of normal primary care, and the complexity of the current glycaemic categorisation of T2DM risk. NDPS identifies people at highest risk of T2DM on the databases of 135 general practices in the East of England for further screening with ab fasting plasma glucose and glycosylated haemoglobin [HbA1c]. Those with an elevated fasting plasma glucose [impaired fasting glucose or IFG] with or without an elevated HbA1c [non -diabetic hyperglycaemia; NDH] are randomised into three treatment arms: a control arm receiving no trial intervention, an arm receiving an intensive bespoke group-based diet and physical activity intervention, and an arm receiving the same intervention with enhanced support from people with T2DM trained as diabetes prevention mentors [DPM]. The primary end point is cumulative transition rates to T2DM between the two intervention groups, and between each intervention group and the control group at 46 months. Participants with screen detected T2DM are randomized into an equivalent prospective controlled trial with the same intervention and control arms with glycaemic control [HbA1c] at 46 months as the primary end point. Participants with NDH and a normal fasting plasma glucose are randomised into an equivalent prospective controlled intervention trial with follow up for 40 months. The intervention comprises six education sessions for the first 12 weeks and then up to 15 maintenance sessions until intervention end, all delivered in groups, with additional support from a DPM in one treatment arm. The NDPS programme reports in 2018 and will provide trial outcome data for a group delivered

    Full Text Available Abstract Background Studies in adult intensive care have highlighted the importance of insulin and improved glucose control on survival, with 32% reduction in mortality, 22% reduction in intensive care stay and halving of the incidence of bacteraemia. Very low birth weight infants requiring intensive care also have relative insulin deficiency often leading to hyperglycaemia during the first week of life. The physiological influences on insulin secretion and sensitivity, and the potential importance of glucose control at this time are not well established. However there is increasing evidence that the early postnatal period is critical for pancreatic development. At this time a complex set of signals appears to influence pancreatic development and β cell survival. This has implications both in terms of acute glucose control but also relative insulin deficiency is likely to play a role in poor postnatal growth, which has been associated with later motor and cognitive impairment, and fewer β cells are linked to risk of type 2 diabetes later in life.

    Lixisenatide is a once-daily, prandial, short-acting glucagon-like peptide-1 receptor agonist. Its main antidiabetic effect is to delay gastric emptying to control postprandial plasma glucose excursions. The dose-response relationship of the integrated insulinotropic and gastrostatic response to lixisenatide in healthy volunteers after a standardized liquid meal was investigated. Twenty healthy subjects received acetaminophen 1000 mg with a standardized liquid meal 60 min after a single subcutaneous injection of placebo or lixisenatide 2.5, 5, 10 or 20 µg in randomized order separated by a 2- to 7-day washout. Acetaminophen pharmacokinetics served as a surrogate to assess rate of gastric emptying. Postprandial plasma glucose, insulin, C-peptide and glucagon were assessed for 5 h after the meal test, and lixisenatide pharmacokinetics were determined for 6 h. After lixisenatide administration and prior to the standardized meal, insulin and C-peptide transiently increased, while fasting plasma glucose decreased in a dose-dependent manner. After the meal, postprandial plasma glucose, insulin and C-peptide were dose proportionally reduced with lixisenatide versus placebo for up to 6 h. Compared with placebo, glucagon levels were transiently lower after any lixisenatide dose, with more sustained reductions after the meal and no apparent dose-related trends. Acetaminophen absorption was significantly reduced and delayed compared with placebo for lixisenatide doses ≥5 µg and demonstrated dose-dependent slowing of gastric emptying. Lixisenatide displayed near dose-proportional exposure, with gastrointestinal events increasing with dose. Lixisenatide reduced fasting plasma glucose via stimulation of glucose-dependent insulin release and controlled postprandial plasma glucose by delaying gastric emptying, demonstrating it to be a valuable option for overall glycaemic control. © 2014 The Authors.

    Sensory and cognitive impairments have been documented in diabetic humans and animals, but the pathophysiology of diabetes in the central nervous system is poorly understood. Because a high glucose level disrupts gap junctional communication in various cell types and astrocytes are extensively coupled by gap junctions to form large syncytia, the influence of experimental diabetes on gap junction channel-mediated dye transfer was assessed in astrocytes in tissue culture and in brain slices from diabetic rats. Astrocytes grown in 15-25 mmol/l glucose had a slow-onset, poorly reversible decrement in gap junctional communication compared with those grown in 5.5 mmol/l glucose. Astrocytes in brain slices from adult STZ (streptozotocin)-treated rats at 20-24 weeks after the onset of diabetes also exhibited reduced dye transfer. In cultured astrocytes grown in high glucose, increased oxidative stress preceded the decrement in dye transfer by several days, and gap junctional impairment was prevented, but not rescued, after its manifestation by compounds that can block or reduce oxidative stress. In sharp contrast with these findings, chaperone molecules known to facilitate protein folding could prevent and rescue gap junctional impairment, even in the presence of elevated glucose level and oxidative stress. Immunostaining of Cx (connexin) 43 and 30, but not Cx26, was altered by growth in high glucose. Disruption of astrocytic trafficking of metabolites and signalling molecules may alter interactions among astrocytes, neurons and endothelial cells and contribute to changes in brain function in diabetes. Involvement of the microvasculature may contribute to diabetic complications in the brain, the cardiovascular system and other organs.

    2011-10-01

    Full Text Available Abstract Background Total knee replacement (TKR is a common and effective surgical procedure to relieve advanced knee arthritis that persists despite comprehensive medical treatment. Although TKR has excellent technical outcomes, significant variation in patient-reported functional improvement post-TKR exists. Evidence suggests that consistent post-TKR exercise and physical activity is associated with functional gain, and that this relationship is influenced by emotional health. The increasing use of TKR in the aging US population makes it critical to find strategies that maximize functional outcomes. Methods/Design This randomized clinical trial (RCT will test the efficacy of a theory-based telephone-delivered Patient Self-Management Support intervention that seeks to enhance adherence to independent exercise and activity among post- TKR patients. The intervention consists of 12 sessions, which begin prior to surgery and continue for approximately 9 weeks post-TKR. The intervention condition will be compared to a usual care control condition using a randomized design and a probabilistic sample of men and women. Assessments are conducted at baseline, eight weeks, and six- and twelve- months. The project is being conducted at a large healthcare system in Massachusetts. The study was designed to provide greater than 80% power for detecting a difference of 4 points in physical function (SF36/Physical Component Score between conditions (standard deviation of 10 at six months with secondary outcomes collected at one year, assuming a loss to follow up rate of no more than 15%. Discussion As TKR use expands, it is important to develop methods to identify patients at risk for sub-optimal functional outcome and to effectively intervene with the goal of optimizing functional outcomes. If shown efficacious, this peri-TKR intervention has the potential to change the paradigm for successful post-TKR care. We hypothesize that Patient Self-Management Support to enhance adherence to independent activity and exercise will enhance uniform, optimal improvement in post-TKR function and patient autonomy, the ultimate goals of TKR.

    Full Text Available With the epidemic of morbid obesity, bariatric surgery has been accepted as one of the most effective treatments of obesity.To investigate recent changes in the utilization of bariatric surgery, patients and hospital characteristics, and in-hospital complications in a nationwide hospital database in the United States.This is a secondary data analysis of the Premier Perspective database.ICD-9 codes were used to identify bariatric surgeries performed between 2011 and 2014. Descriptive statistics were computed and regression was used.A total of 74,774 bariatric procedures were identified from 436 hospitals between 2011 and 2014. During this time period, the proportion of gastric bypass (from 44.8% to 31.3%; P for trend < 0.0001 and gastric banding (from 22.8% to 5.2%; P for trend < 0.0001 decreased, while the proportion of sleeve gastrectomy (from 13.7% to 56.9%; P for trend < 0.0001 increased substantially. The proportion of bariatric surgery performed for outpatients decreased from 17.15% in 2011 to 8.11% in 2014 (P for trend < 0.0001. The majority of patients undergoing surgery were female (78.5%, white (65.6%, younger than 65 years (93.8%, and insured with managed care (53.6%. In-hospital mortality rate and length of hospital stay remained stable. The majority of surgeries were performed in high-volume (71.8% and urban (91.6% hospitals.Results based on our study sample indicated that the popularity of various bariatric surgery procedures changed significantly from 2011 to 2014. While the rates of in-hospital complications were stable, disparities in the use of bariatric surgery regarding gender, race, and insurance still exist.

    Full Text Available El tratamiento del paciente que recibe terapias que afectan la hemostasia normal (anticoagulantes y/o antiagregantes plaquetarios y que será sometido a un procedimiento quirúrgico, es uno de los retos que se presentan cada vez con mayor frecuencia en los servicios de cardiología. La toma de la mejor opción terapéutica en este grupo de pacientes requiere un profundo conocimiento sobre los riesgos de sangrado en caso de continuarse el tratamiento, frente a los riesgos de trombosis o embolismo en caso de suspenderlo. Por tradición, esa decisión se ha basado más en el temor al riesgo de sangrado, por lo cual en muchos casos se ha suspendido dicha terapia de manera innecesaria. En los últimos años, la aparición de la evidencia que indica que no sólo no es alto el riesgo de sangrado sino que además la continuación de estos medicamentos en muchos casos disminuye desenlaces adversos mayores, ha llevado a replantear esta conducta. En este artículo se revisará la evidencia actual existente al respecto y se suministrarán pautas que permitan la toma de una decisión adecuada.Treatment of patients receiving therapies that affect normal hemostasis (anticoagulants and / or anti-platelet aggregators and that will undergo surgery, is one of the challenges that arise with increasing frequency in the cardiology services. Making the best therapeutic option in these patients requires a thorough understanding of the risks of bleeding in case of continuing the treatment against the risks of thrombosis or embolism in case of stopping it. By tradition, this decision has been based more on fear to the risk of bleeding, whereby in many cases this therapy has been suspended unnecessarily. In recent years, the emergence of evidence indicates that the risk of bleeding is not high and that continuation of these drugs in many cases reduce major adverse outcomes. This has led to redefine this behavior. In this article we review the current evidence available on the subject and provide guidelines that allow making a right decision.

    The clinical role of hyperoxia for preventing surgical site infection (SSI) remains uncertain because randomized controlled trials on this topic have reported disparate results. One of the principal reasons for this outcome may be that prior trials have entered heterogeneous populations of patients and a variety of procedures. The aim of our study was to assess the influence of hyperoxygenation on SSI using a homogeneous study population. From January 2004 to April 2013, we studied, in a randomized trial, 239 patients, who underwent open surgery for perforated peptic ulcer (PPU). The surgical procedure was performed through an upper abdominal midline incision, and closure of PPU was achieved by suture alone or in combination with an omental patch. Patients were assigned randomly to an oxygen/air mixture with a fraction of inspired oxygen (FiO2) of 30% (n = 120) or 80% (n = 119). Administration was commenced after induction of anesthesia and maintained for 6 hours after surgery. The overall incision infection rate was 38.4% (92 of 239): 61 patients (50.8%) had an infection in the 30% FiO2 group and 31 (26%) in the 80% FiO2 group (p operative SSI, should be considered part of ongoing quality improvement activities related to surgical care, with few risks to the patient and little associated cost.

    Studies have examined infection rates following spine surgery and their relationship to post-operative complications and increased length of stay. Few studies, however, have investigated predictors of infection, specifically in the setting of operative intervention for cervical spondylotic myelopathy (CSM). This study aims to identify the incidence and factors predictive of infection amongst this cohort. This study performed a retrospective review of the prospectively collected American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Patients included those treated surgically for CSM (ICD-9 code 721.1) from 2010 to 2012. Patient demographics and surgical data were collected with outcome variables including the occurrence of one of the following surgical site infections (SSIs) within 30 days of index operation: superficial SSI, deep incisional SSI, and organ/space SSI. 3057 patients were included in this analysis. Overall infection rate was 1.15 % (35/3057), of which 54.3 % (19/35) were superficial SSIs, 28.6 % (10/35) were deep incisional SSI, and 20 % (7/35) were peri-spinal SSI. Logistic regression revealed factors associated with SSI included: higher BMI [OR 1.162 (CI 1.269-1.064), p = 0.001] and operative time ≥208 min [OR 4.769 (CI 20.220-1.125), p = 0.034]. The overall SSI rate for the examined CSM cohort was 1.15 %. This study identified increased BMI and operative time ≥208 min as predictors of infection in surgical CSM patients. This information should be carefully considered in delivering patient education and future efforts to optimize risk in CSM patients indicated for surgical intervention.

    Patients on a left ventricular assist device (LVAD) often have a high level of panel-reactive antibodies (PRA). Conventional therapy is to await a heart from a negative prospective-crossmatch donor. We transplanted three high-PRA patients with non-crossmatched hearts, using intra- and post-operative plasmapheresis and long-term T-/B-/plasma-cell therapy with alemtuzumab. Three highly sensitized patients (70%, 94% and 96% T-PRA; 63%, 24% and 73% B-PRA) were transplanted after 29, 187 and 94 days LVAD support. The first patient (Case 1) had an erroneous prospective negative crossmatch (due to an outside laboratory's use of the wrong patient's serum) with immediate allograft dysfunction. The correct serum showed a strongly positive crossmatch; plasmapheresis followed by alemtuzumab (20 mg intravenously) shortly after arrival in the ICU resulted in rapid hemodynamic improvement. Encouraged by this success, the next two patients (Cases 2 and 3) underwent LVAD explant and heart transplant with the next available ABO-identical, non-crossmatched donors, using plasmapheresis on bypass immediately before heart implant and alemtuzumab 20 mg intravenously upon ICU arrival, with uneventful courses. All three patients had positive retrospective T- and B-cell crossmatches. Maintenance immunosuppression consisted of cyclosporine and routine prednisone taper, with plasmapheresis as needed (Patient 1, x10; Patient 2, x5) based on diastolic dysfunction. Mycophenolate mofetil was started as a third agent several months post-transplant. Patients are presently New York Heart Association (NYHA) Class I at 26, 16 and 13 months post-transplant. In this small series with follow-up, immediate antibody removal with plasmapheresis, combined with alemtuzumab, a long-acting antibody to CD52 (expressed on T, B and some plasma cells), appears effective in allowing transplantation in sensitized, positive crossmatch recipients. Expanded use of this strategy could shorten LVAD support in many sensitized patients.

    Surgical pain is managed with multi-modal anaesthesia in total hip replacement (THR) and total knee replacement (TKR). It is unclear whether including local anaesthetic infiltration before wound closure provides additional pain control. We performed a systematic review of randomised controlled trials of local anaesthetic infiltration in patients receiving THR or TKR. We searched MEDLINE, Embase and Cochrane CENTRAL to December 2012. Two reviewers screened abstracts, extracted data, and contacted authors for unpublished outcomes and data. Outcomes collected were post-operative pain at rest and during activity after 24 and 48 hours, opioid requirement, mobilisation, hospital stay and complications. When feasible, we estimated pooled treatment effects using random effects meta-analyses. In 13 studies including 909 patients undergoing THR, patients receiving local anaesthetic infiltration experienced a greater reduction in pain at 24 hours at rest by standardised mean difference (SMD) -0.61 (95% CI -1.05, -0.16; p = 0.008) and by SMD -0.43 (95% CI -0.78 -0.09; p = 0.014) at 48 hours during activity.In TKR, diverse multi-modal regimens were reported. In 23 studies including 1439 patients undergoing TKR, local anaesthetic infiltration reduced pain on average by SMD -0.40 (95% CI -0.58, -0.22; p SMD -0.27 (95% CI -0.50, -0.05; p = 0.018) at 48 hours during activity, compared with patients receiving no infiltration or placebo. There was evidence of a larger reduction in studies delivering additional local anaesthetic after wound closure. There was no evidence of pain control additional to that provided by femoral nerve block.Patients receiving local anaesthetic infiltration spent on average an estimated 0.83 (95% CI 1.54, 0.12; p = 0.022) and 0.87 (95% CI 1.62, 0.11; p = 0.025) fewer days in hospital after THR and TKR respectively, had reduced opioid consumption, earlier mobilisation, and lower incidence of vomiting.Few studies reported long-term outcomes. Local anaesthetic infiltration is effective in reducing short-term pain and hospital stay in patients receiving THR and TKR. Studies should assess whether local anaesthetic infiltration can prevent long-term pain. Enhanced pain control with additional analgesia through a catheter should be weighed against a possible infection risk.

    A patient with a medial and posterior dislocation of the right sterno-clavicular (SC) joint and displacement of the trachea and brachiocephalic artery by the medial head of the clavicle underwent general anaesthetic in the operating theatre for an open reduction procedure. The surgeon initially attempted a closed reduction, but this required imaging to check SC alignment. The patient was transferred to an adjacent hybrid operating theatre for imaging. Cone beam computed tomography (CBCT) was performed, which successfully demonstrated a significant reduction in the dislocation of the SC joint. The trachea and brachiocephalic artery were no longer compressed or displaced. This case study demonstrates an alternative to the patient being transferred to the medical imaging department for multi-slice CT. It also describes a novel use of the hybrid operating theatre and its CBCT capabilities.

    2017-02-01

    Early rehabilitation is recommended in many guidelines, with limited evidence to guide practice. Brain neurobiology suggests that early training, at the right dose, will aid recovery. In this review, we highlight recent trials of early mobilization, aphasia, dysphagia and upper limb treatment in which intervention is commenced within 7 days of stroke and discuss future research directions. Trials in this early time window are few. Although the seminal AVERT trial suggests that a cautious approach is necessary immediately (stroke, early mobility training and mobilization appear well tolerated, with few reasons to delay initiating some rehabilitation within the first week. The results of large clinical trials of early aphasia therapy are on the horizon, and examples of targeted upper limb treatments with better patient selection are emerging. Early rehabilitation trials are complex, particularly those that intervene across acute and rehabilitation care settings, but these trials are important if we are to optimize recovery potential in the critical window for repair. Concerted efforts to standardize 'early' recruitment, appropriately stratify participants and implement longer term follow-up is needed. Trial standards are improving. New recommendations from a recent Stroke Recovery and Rehabilitation Roundtable will help drive new research.

    Atypical antipsychotics have a favourable risk/benefit profile in early onset schizophrenia (EOS). However, despite increasing use of psychotropic medication in children and adolescents, their endocrine and metabolic side-effects (weight gain, obesity, and related metabolic abnormalities such as hyperglycaemia and dyslipidemia) are of particular concern, especially within this paediatric population that appears to be at greater risk as compared with adults for antipsychotic-induced metabolic adverse effects. In addition to medication, many factors contribute to weigh gain in psychiatric patients, including sedentary lifestyle and poor diet. Excessive weigh gain has several deleterious effects in psychiatric patients, including stigmatization and further social withdrawal, and non compliance with medication. Furthermore, excessive corpulence may evolve to a metabolic syndrome with a high-risk state for future cardiovascular morbidity and mortality in adult age. Because youths are still developing at the time of psychotropic drug exposure, in a context of physiological changes in hormonal and endocrines levels and body composition, most reference values need to be adjusted for gender, age and growth charts. Hence, sex- and age-adjusted BMI percentiles and BMI Z scores are crucial to assess weight gain in children and adolescents. Obesity thresholds have been proposed to define "at risk" categories of patients. In recently issued guidelines, thresholds for antipsychotic-induced weight gain in adults have been set at a 5% increase or one point increase in BMI unit. To date, no definition has reached a consensus in childhood and adolescence. However, some at risk states requiring action are proposed in literature: more than 5% increase in weight within a three-month period; more than half a point increase in BMI Z score; between 85th and 95th BMI percentile plus one adverse health consequence (i.e. hyperglycaemia, dyslipidemia, hyperinsulinemia, hypertension, or

    Background and Objective A robust release of endothelin-1-1 (ET) with subsequent ETA subtype receptor (ET-AR) activation occurs in patients following cardiac surgery requiring cardiopulmonary bypass (CPB). Increased ET-AR activation has been identified in patients with poor LV function (reduced ejection fraction; EF). Accordingly, this study tested the hypothesis that a selective ET-AR antagonist (ET-ARA) administered peri-operatively would favorably affect post-CPB hemodynamic profiles in patients with a pre-existing poor LVEF. Methods and Results Patients (n=29; 66±2 yrs) with a reduced LVEF (37±2%) were prospectively randomized, in a blinded fashion, at the time of elective coronary revascularization and/or valve replacement requiring CPB, to infusion of the highly-selective and potent ET-ARA, sitaxsentan at 1 or 2 mg/kg (IV bolus; n=9, 10 respectively) or vehicle (saline; n=10). Infusion of the ET-ARA/vehicle was performed immediately prior to separation from CPB and again at 12 hrs post-CPB. ET and hemodynamic measurements were performed at baseline, at separation from CPB (Time 0) and at 0.5, 6, 12, 24 hrs post-CPB. Baseline plasma ET (4.0±0.3 fmol/mL) was identical across all 3 groups, but when compared to pre-operative, baseline values obtained from age matched subjects with a normal LVEF (n=37;LVEF>50%), were significantly increased (2.9±0.2 fmol/mL, pTime 0, SVR changed in an equivalent fashion in the post-CPB period, but a significant ET-ARA effect was observed for PVR (ANOVA; p<0.05). For example at 24 hrs post-CPB, PVR increased by 40 d.scm-5 in the vehicle group, but directionally decreased by over 40 d·s·cm-5 in the 2 mg/kg ETARA group (p<0.05). Total adverse events were equivalently distributed across the ET-ARA/placebo groups. Conclusions These unique findings demonstrated that infusion of an ET-ARA in high risk cardiac surgery patients was not associated with significant hemodynamic compromise. Moreover, ET-ARA favorably affected PVR in the

    1998-01-01

    Understanding our own early biosphere is essential to our search for life elsewhere, because life arose on Earth very early and rocky planets shared similar early histories. The biosphere arose before 3.8 Ga ago, was exclusively unicellular and was dominated by hyperthermophiles that utilized chemical sources of energy and employed a range of metabolic pathways for CO2 assimilation. Photosynthesis also arose very early. Oxygenic photosynthesis arose later but still prior to 2.7 Ga. The transition toward the modern global environment was paced by a decline in volcanic and hydrothermal activity. These developments allowed atmospheric O2 levels to increase. The O2 increase created new niches for aerobic life, most notably the more advanced Eukarya that eventually spawned the megascopic fauna and flora of our modern biosphere.

    BACKGROUND: Although the benefits of early tracheostomy in patients dependent on ventilators are well established, the reasons for variation in time from intubation to tracheostomy remain unclear. We identified clinical and demographic disparities in time to tracheostomy. METHODS: We performed a level 3 retrospective prognostic study by querying the University HealthSystem Consortium (2007-2010) for adult patients receiving a tracheostomy after initial intubation. Time to tracheostomy was designated early ( 10 days). Cohorts were stratified by time to tracheostomy and compared using univariate tests of association and multivariable adjusted models. RESULTS: A total of 49,191 patients underwent tracheostomy after initial intubation: 42% early (n = 21,029) and 58% late (n = 28,162). On both univariate and multivariable analyses, women, blacks, Hispanics, and patients receiving Medicaid were less likely to receive an early tracheostomy. Patients in the early group also experienced lower rates of mortality (OR, 0.84; 95% CI, 0.79-0.88). CONCLUSIONS: Early tracheostomy was associated with increased survival. Yet, there were still significant disparities in time to tracheostomy according to sex, race, and type of insurance. Application of evidence-based algorithms for tracheostomy may reduce unequal treatment and improve overall mortality rates. Additional research into this apparent bias in referral/rendering of tracheostomy is needed. PMID:26313324

    We investigate our knowledge of early universe cosmology by exploring how much additional energy density can be placed in different components beyond those in the ΛCDM model. To do this we use a method to separate early- and late-universe information enclosed in observational data, thus markedly reducing the model-dependency of the conclusions. We find that the 95% credibility regions for extra energy components of the early universe at recombination are: non-accelerating additional fluid density parameter Ω{sub MR} < 0.006 and extra radiation parameterised as extra effective neutrino species 2.3 < N {sub eff} < 3.2 when imposing flatness. Our constraints thus show that even when analyzing the data in this largely model-independent way, the possibility of hiding extra energy components beyond ΛCDM in the early universe is seriously constrained by current observations. We also find that the standard ruler, the sound horizon at radiation drag, can be well determined in a way that does not depend on late-time Universe assumptions, but depends strongly on early-time physics and in particular on additional components that behave like radiation. We find that the standard ruler length determined in this way is r {sub s} = 147.4 ± 0.7 Mpc if the radiation and neutrino components are standard, but the uncertainty increases by an order of magnitude when non-standard dark radiation components are allowed, to r {sub s} = 150 ± 5 Mpc.

    2015-01-01

    Concepts regarding osteoarthritis, the most common joint disease, have dramatically changed in the past decade thanks to the development of new imaging techniques and the widespread use of arthroscopy that permits direct visualisation of intra-articular tissues and structure. MRI and ultrasound allow the early detection of pre-radiographic structural changes not only in the peri-articular bone but also in the cartilage, menisci, synovial membrane, ligaments and fat pad. The significance of MRI findings such as cartilage defects, bone marrow lesions, synovial inflammation/effusions and meniscal tears in patients without radiographic signs of osteoarthritis is not fully understood. Nevertheless, early joint tissue changes are associated with symptoms and, in some cases, with progression of disease. In this short review, we discuss the emerging concept of early osteoarthritis localised to the knee based on recently updated knowledge. We highlight the need for a new definition of early osteoarthritis that will permit the identification of patients at high risk of osteoarthritis progression and to initiate early treatment interventions.

  13. Early Dementia Screening

    2016-01-01

    Full Text Available As the population of the world increases, there will be larger numbers of people with dementia and an emerging need for prompt diagnosis and treatment. Early dementia screening is the process by which a patient who might be in the prodromal phases of a dementing illness is determined as having, or not having, the hallmarks of a neurodegenerative condition. The concepts of mild cognitive impairment, or mild neurocognitive disorder, are useful in analyzing the patient in the prodromal phase of a dementing disease; however, the transformation to dementia may be as low as 10% per annum. The search for early dementia requires a comprehensive clinical evaluation, cognitive assessment, determination of functional status, corroborative history and imaging (including MRI, FDG-PET and maybe amyloid PET, cerebrospinal fluid (CSF examination assaying Aβ1–42, T-τ and P-τ might also be helpful. Primary care physicians are fundamental in the screening process and are vital in initiating specialist investigation and treatment. Early dementia screening is especially important in an age where there is a search for disease modifying therapies, where there is mounting evidence that treatment, if given early, might influence the natural history—hence the need for cost-effective screening measures for early dementia.

    A 290-million-year-old reptilian skeleton from the Lower Permian (Asselian) of Germany provides evidence of abilities for cursorial bipedal locomotion, employing a parasagittal digitigrade posture. The skeleton is of a small bolosaurid, Eudibamus cursoris, gen. et sp. nov. and confirms the widespread distribution of Bolosauridae across Laurasia during this early stage of amniote evolution. E. cursoris is the oldest known representative of Parareptilia, a major clade of reptiles.

    Questions surrounding the origin and early evolution of primates continue to be the subject of debate. Though anatomy of the skull and inferred dietary shifts are often the focus, detailed studies of postcrania and inferred locomotor capabilities can also provide crucial data that advance understanding of transitions in early primate evolution. In particular, the hand skeleton includes characteristics thought to reflect foraging, locomotion, and posture. Here we review what is known about the early evolution of primate hands from a comparative perspective that incorporates data from the fossil record. Additionally, we provide new comparative data and documentation of skeletal morphology for Paleogene plesiadapiforms, notharctines, cercamoniines, adapines, and omomyiforms. Finally, we discuss implications of these data for understanding locomotor transitions during the origin and early evolutionary history of primates. Known plesiadapiform species cannot be differentiated from extant primates based on either intrinsic hand proportions or hand-to-body size proportions. Nonetheless, the presence of claws and a different metacarpophalangeal [corrected] joint form in plesiadapiforms indicate different grasping mechanics. Notharctines and cercamoniines have intrinsic hand proportions with extremely elongated proximal phalanges and digit rays relative to metacarpals, resembling tarsiers and galagos. But their hand-to-body size proportions are typical of many extant primates (unlike those of tarsiers, and possibly Teilhardina, which have extremely large hands). Non-adapine adapiforms and omomyids exhibit additional carpal features suggesting more limited dorsiflexion, greater ulnar deviation, and a more habitually divergent pollex than observed plesiadapiforms. Together, features differentiating adapiforms and omomyiforms from plesiadapiforms indicate increased reliance on vertical prehensile-clinging and grasp-leaping, possibly in combination with predatory behaviors in

    2017-01-01

    Falling scores in math have prompted a renewed interest in math instruction at early ages. By their own admission, early childhood educators are generally underprepared and not always comfortable teaching math. Professional development (PD) in early mathematics is widely considered a main way to increase teachers' skills and efficacy (e.g., Guskey, 2000; Hyson & Woods, 2014; Munby, Russell, & Martin, 2001; Piasta, Logan, Pelatti, Capps, & Petrill, 2015; Richardson & Placier, 2001; Sarama, Clements, Wolfe, & Spitler, 2016; Sarama & DiBiase, 2004; Zaslow, 2014). However, it has been documented that stand-alone PD is not as effective in changing practice (e.g., Biancarosa & Bryk, 2011; Garet et al., 2008; Guskey, 2000; Hyson & Woods, 2014; Institute of Medicine and National Research Council, 2015; Joyce & Showers, 2002; Zaslow, 2014). Site-embedded ongoing support in the form of coaching or mentoring has been shown to be critical for successful implementation (Neuman & Cunningham, 2009; Powell, Diamond, Burchinal, & Koehler, 2010). In this chapter, we describe coaching models and abstract characteristics of effective coaching from the research. With this background, we provide an in-depth view of the coaching aspect of two large empirical studies in early mathematics. We introduce the theoretical framework from which the coaching models for these projects were developed and describe the research on which they were based. We then summarize how the planned models were instantiated and challenges to their implementation within each project. In the final section, we summarize what we have learned and described implications and challenges for the field. © 2017 Elsevier Inc. All rights reserved.

  19. Early anaerobic metabolisms

    Canfield, Don E; Rosing, Minik T; Bjerrum, Christian

    2006-01-01

    Before the advent of oxygenic photosynthesis, the biosphere was driven by anaerobic metabolisms. We catalogue and quantify the source strengths of the most probable electron donors and electron acceptors that would have been available to fuel early-Earth ecosystems. The most active ecosystems were probably driven by the cycling of H2 and Fe2+ through primary production conducted by anoxygenic phototrophs. Interesting and dynamic ecosystems would have also been driven by the microbial cycling of sulphur and nitrogen species, but their activity levels were probably not so great. Despite the diversity of potential early ecosystems, rates of primary production in the early-Earth anaerobic biosphere were probably well below those rates observed in the marine environment. We shift our attention to the Earth environment at 3.8 Gyr ago, where the earliest marine sediments are preserved. We calculate, consistent with the carbon isotope record and other considerations of the carbon cycle, that marine rates of primary production at this time were probably an order of magnitude (or more) less than today. We conclude that the flux of reduced species to the Earth surface at this time may have been sufficient to drive anaerobic ecosystems of sufficient activity to be consistent with the carbon isotope record. Conversely, an ecosystem based on oxygenic photosynthesis was also possible with complete removal of the oxygen by reaction with reduced species from the mantle. PMID:17008221

  20. Early intervention for psychosis

    Marshall, Max; Rathbone, John

    2014-01-01

    Background Proponents of early intervention have argued that outcomes might be improved if more therapeutic efforts were focused on the early stages of schizophrenia or on people with prodromal symptoms. Early intervention in schizophrenia has two elements that are distinct from standard care: early detection, and phase-specific treatment (phase-specific treatment is a psychological, social or physical treatment developed, or modified, specifically for use with people at an early stage of the illness). Early detection and phase-specific treatment may both be offered as supplements to standard care, or may be provided through a specialised early intervention team. Early intervention is now well established as a therapeutic approach in America, Europe and Australasia. Objectives To evaluate the effects of: (a) early detection; (b) phase-specific treatments; and (c) specialised early intervention teams in the treatment of people with prodromal symptoms or first-episode psychosis. Search methods We searched the Cochrane Schizophrenia Group Trials Register (March 2009), inspected reference lists of all identified trials and reviews and contacted experts in the field. Selection criteria We included all randomised controlled trials (RCTs) designed to prevent progression to psychosis in people showing prodromal symptoms, or to improve outcome for people with first-episode psychosis. Eligible interventions, alone and in combination, included: early detection, phase-specific treatments, and care from specialised early intervention teams. We accepted cluster-randomised trials but excluded non-randomised trials. Data collection and analysis We reliably selected studies, quality rated them and extracted data. For dichotomous data, we estimated relative risks (RR), with the 95% confidence intervals (CI). Where possible, we calculated the number needed to treat/harm statistic (NNT/H) and used intention-to-treat analysis (ITT). Main results Studies were diverse, mostly small

    Full Text Available Werner syndrome (WS is a rare autosomal recessive adult-onset progeroid disorder characterized by the early onset of aged-appearance and age-related metabolic disorders. Symptoms of premature aging usually first develop in the second-third decades of life. We report a 27-year-old female who was admitted to our clinic at the age of eighteen with hyperglycemia. She was diagnosed with diabetes and type 4 dyslipidemia at the age of seven. In her family history, her parents were first cousins and she had three healthy brothers. On her first physical examination; she had bird-like face appearance, global hair loss, beaked nose, short stature and she was overweight. She had global hair loss with gray and thin hair. Hoarseness of voice and hyperkeratosis of skin were observed. She had bilateral cataracts and moderate sensorineural hearing loss. On psychiatric examination, borderline mental retardation was detected. She had severe insulin resistance and hypertriglyceridemia despite levothyroxine, gemfibrozil, omega-3 and intensive insulin treatment. Routine lipid apheresis was performed to lower the triglyceride levels reaching 5256 mg/dL. She also had focal segmental glomerulosclerosis, hepatosteatosis, osteoporosis and epilepsy. Disease was accompanied by several congenital deformities, such as Rathke’s cleft cyst, angiomyolipoma and femoral neck hypoplasia. WS is a rare genetic disorder characterized by multiple endocrine manifestations as well as soft tissue changes. We present a case of early disturbances that were diagnosed before typical clinical signs and symptoms. We propose that WS should be kept in mind when type 2 diabetes and hyperlipidemia are diagnosed early in childhood. Turk Jem 2015; 19: 99-104

    Earthquake early warning (EEW) can reduce harm to people and infrastructure from earthquakes and tsunamis, but it has not been implemented in most high earthquake-risk regions because of prohibitive cost. Common consumer devices such as smartphones contain low-cost versions of the sensors used in EEW. Although less accurate than scientific-grade instruments, these sensors are globally ubiquitous. Through controlled tests of consumer devices, simulation of an Mw (moment magnitude) 7 earthquake on California’s Hayward fault, and real data from the Mw 9 Tohoku-oki earthquake, we demonstrate that EEW could be achieved via crowdsourcing.

    2011-12-01

    Over the last decade, the search for a method able to reliably predict seizures hours in advance has been largely replaced by the more realistic goal of very early detection of seizure onset, which would allow therapeutic or warning devices to be triggered prior to the onset of disabling clinical symptoms. We explore in this article the steps along the pathway from data acquisition to closed-loop applications that can and should be considered to design the most efficient early seizure detection. Microelectrodes, high-frequency oscillations, high sampling rate, high-density arrays, and modern analysis techniques are all elements of the recording and detection process that in combination with modeling studies can provide new insights into the dynamics of seizure onsets. Each of these steps needs to be considered if detection devices that will favorably impact the quality of life of patients are to be implemented.

  15. Manipulating early pig embryos.

    Science.gov (United States)

    Niemann, H; Reichelt, B

    1993-01-01

    On the basis of established surgical procedures for embryo recovery and transfer, the early pig embryo can be subjected to various manipulations aimed at a long-term preservation of genetic material, the generation of identical multiplets, the early determination of sex or the alteration of the genetic make-up. Most of these procedures are still at an experimental stage and despite recent considerable progress are far from practical application. Normal piglets have been obtained after cryopreservation of pig blastocysts hatched in vitro, whereas all attempts to freeze embryos with intact zona pellucida have been unsuccessful. Pig embryos at the morula and blastocyst stage can be bisected microsurgically and the resulting demi-embryos possess a high developmental potential in vitro, whereas their development in vivo is impaired. Pregnancy rates are similar (80%) but litter size is reduced compared with intact embryos and twinning rate is approximately 2%. Pig blastomeres isolated from embryos up to the 16-cell stage can be grown in culture and result in normal blastocysts. Normal piglets have been born upon transfer of blastocysts derived from isolated eight-cell blastomeres, clearly underlining the totipotency of this developmental stage. Upon nuclear transfer the developmental capacity of reconstituted pig embryos is low and culture. Sex determination can be achieved either by separation of X and Y chromosome bearing spermatozoa by flow cytometry or by analysing the expression of the HY antigen in pig embryos from the eight-cell to morula stage. Microinjection of foreign DNA has been successfully used to alter growth and development of transgenic pigs, and to produce foreign proteins in the mammary gland or in the bloodstream, indicating that pigs can be used as donors for valuable human pharmaceutical proteins. Another promising area of gene transfer is the increase of disease resistance in transgenic lines of pigs. Approximately 30% of pig spermatozoa bind

  16. Consequences of early childbearing.

    Science.gov (United States)

    Monroy De Velasco, A

    1982-12-01

    By 2000, developing countries will have an estimated 1 billion adolescents who are physically old enough to reproduce themselves but far too young to be responsible, healthy parents of healthy children. Governments must become involved in the issues surrounding adolescent pregnancy and both custom and the laws must change to reflect the needs of young people. The consequences of early childbearing are felt by society as well as the families directly affected. The incidence of births to very young women, both married and unmarried is growing; each year approximately 13 million children are born to young mothers. The percentage of live births to mothers under the age of 20 ranges from 20% in some African and Caribbean countries, to 10-15% in many Latin American countries, 5-10% in Asia, and 1% in Japan. Increased out-of-wedlock adolescent pregnancy is due to many factors: earlier sexual maturity from better childhood health and nutrition, a trend toward later marriage, increased opportunity for opposite sex interaction in schools and in the labor force, and rapid urbanization which weakens traditional family structures and social and cultural controls. Early childbirth is especially dangerous for adolescents and their infants. Compared to women between the ages of 20-35, pregnant women under 20 are at a greater risk for death and disease including bleeding during pregnancy, toxemia, hemorrhage, prolonged and difficult labor, severe anemia, and disability. Life-long social and economic disadvantages may be a consequence of teenage birth. Educational and career opportunities may be limited, as may be opportunities for marriage. Teen mothers tend to have larger completed family sizes, shorter birth intervals resulting in both poorer health status for the family, and a more severe level of poverty. The children also suffer; teens mothers have a higher incidence of low birth weight infants which is associated with birth injuries, serious childhood illness, and mental and

    2011-01-01

    The most frequent early symptoms of spondyloarthritides are inflammatory back pain and asymetric peripheral arthritis. Currently the mean delay between the onset of first symptoms and diagnosing ankylosing spondylitis which is the frequent type of spondyloarthritis is over 5 years. The availability of effective therapies makes an early diagnosis mandatory. The clinical symptoms of inflammatory back pain, active inflamation on MR, and positivity for HLA-B27 are the most important parameters for an early diagnosis of spondyloarthritis, especially in combination. Moreover, the combination of clinical and laboratory parameters is necessary for the early diagnosis.

    Full Text Available A 25-years old man from Zagreb, Croatia, was admitted to the University Hospital for Infectious Diseases four days after the onset of symptoms such as fever, intense pain in the calves and anuria. The patient owned a rabbit and, before the onset of the disease, repaired some rubber pipes damaged by rodents. At admission, he had a severe clinical picture with fever, hypotension, jaundice, immobility, and pain in leg muscles. Treatment with ceftriaxone was initiated in combination with volume restitution. Renal failure soon ensued. Consequently continuous venovenous hemodiaphiltration therapy was performed. Due to acute respiratory distress syndrome, the patient was mechanically ventilated. The patient’s condition gradually improved and he recovered fully from multi-organ failure. Diagnosis was confirmed by a microscopic agglutination test (MAT covering 15 leptospira serovars and real-time polymerase-chain reaction (PCR. The first serum sample taken on day 6 tested negative for leptospira, while PCR showed positive results for leptospiral DNA. The second serum sample taken on day 13 tested positive for serovar Canicola serogroup Canicola, serovar Patoc, serovar Grippotyphosa serogroup Grippotyphosa and serovar Tarassovi serogroup Tarassovi (titre 4000, 4000, 1000 and 2000, respectively, while PCR was negative. This report highlights the benefits of combining MAT and PCR methods in early diagnosis of leptospirosis.

    We revisit models for the early history of Titan. Our models start a few My after the production of calcium- aluminum inclusions (CAIs), consistent with the dates required by our thermophysical-dynamical modeling of Saturn's medium-sized satellites. Depending on the time of formation with respect to CAIs, the accretion time scale, and the available accretional energy, models of Titan's interior after accretion are partially to fully differentiated. At one extreme of the models, Titan accretes incorporating a minimal amount of heat. This results in a relatively cold core that, over the long term, heats up and overturns, consistent with previous models of Titan. At the other extreme, accretional heat and heat fom the decay of short-lived radiogenic isotopes results in quick and complete differentiation. In this model there is no core overturn, and conditions soon develop for silicate serpentinization, and hydrothermal activity starts. We identify the periods during which conditions are suitable for hydrothermal geochemistry leading to the production of molecular nitrogen from ammonia decomposition and methane from the Fischer-Tropsch reaction. Key questions include the availability of suitable metal catalysts and/or clay minerals, storage of the reactants and products in the interior of Titan, and mechanisms by which they are released to the atmosphere.

    The overall objective of this project is the three-phase development of an Early Entrance Coproduction Plant (EECP) that produces at least one product from at least two of the following three categories: Electric power (or heat); Fuels; and Chemicals. The objective is to have these products produced by technologies capable of using synthesis gas derived from coal and/or some other carbonaceous feedstock, such as petroleum coke. The objective of Phase I was to determine the feasibility and define the concept for the EECP located at a specific site and to develop a Research, Development, and Testing (RD and T) Plan for implementation in Phase II. This objective has now been accomplished. A specific site, Motiva Refinery in Port Arthur, Texas, has been selected as the location best suited for the EECP. The accomplishments of Phase I are discussed in detail in this Phase I Concept Report. A RD and T Plan and a preliminary project financing plan have been developed and are submitted separately from this report.

  6. Is credit for early action credible early action?

    Credit for early action as a tool for greenhouse gas emissions reduction is compared with various market instruments as a means of narrowing the gap between projected emissions and those of the Kyoto Protocol. Market instruments work by creating a market price for emissions and use the market to encourage reductions at the lowest price, which is done by placing limits on greenhouse gas emissions and allowing the market to decide where reductions occur, or by imposing a carbon tax or emissions charge. While they can be applied within a sector, they are usually used to encourage reductions throughout the economy or across large sectors. Credit for early action also creates an incentive for emissions reductions throughout the economy or at least across many sectors. Credit for early action tools do not work by either imposing a carbon tax or emissions charge or placing limits on emissions, rather they promise that entities that take action against greenhouse gases prior to the imposition of a carbon tax or emissions limits will receive a credit against future taxes or limits. An overview is provided of the Kyoto Protocol and the rationale for taking early action, and a review is included of the theory and specific proposals for market instruments and credit for early action. A comparative analysis is provided of these approaches by examining their relative efficiency, environmental effectiveness, and impacts on the redistribution of wealth. Credit for early action is viewed as problematic on a number of counts and is seen as an interim strategy for imposition while political support for market instruments develop. The environmental effectiveness of credit for early action is very difficult to predict, and credit for early action programs do not yield the lowest cost emissions reductions. Credit for early action programs will not achieve compliance with the Kyoto Protocol at the lowest cost, and credits for early action will increase the compliance costs for those who

    In an attempt to investigate differences between the most widely discussed hypotheses of early tetrapod relationships, we assembled a new data matrix including 90 taxa coded for 319 cranial and postcranial characters. We have incorporated, where possible, original observations of numerous taxa spread throughout the major tetrapod clades. A stem-based (total-group) definition of Tetrapoda is preferred over apomorphy- and node-based (crown-group) definitions. This definition is operational, since it is based on a formal character analysis. A PAUP* search using a recently implemented version of the parsimony ratchet method yields 64 shortest trees. Differences between these trees concern: (1) the internal relationships of aïstopods, the three selected species of which form a trichotomy; (2) the internal relationships of embolomeres, with Archeria crassidisca and Pholiderpeton scut collapsed in a trichotomy with a clade formed by Anthracosaurus russelli and Pholiderpeton attheyi; (3) the internal relationships of derived dissorophoids, with four amphibamid species forming an unresolved node with a clade consisting of micromelerpetontids and branchiosaurids and a clade consisting of albanerpetontids plus basal crown-group lissamphibians; (4) the position of albenerpetontids and Eocaecilia micropoda, which form an unresolved node with a trichotomy subtending Karaurus sharovi, Valdotriton gracilis and Triadobatrachus massinoti; (5) the branching pattern of derived diplocaulid nectrideans, with Batrachiderpeton reticulatum and Diceratosaurus brevirostris collapsed in a trichotomy with a clade formed by Diplocaulus magnicornis and Diploceraspis burkei. The results of the original parsimony run--as well as those retrieved from several other treatments of the data set (e.g. exclusion of postcranial and lower jaw data; character reweighting; reverse weighting)--indicate a deep split of early tetrapods between lissamphibian- and amniote-related taxa.

    Full Text Available Abstract Background Ocular sebaceous carcinoma can masquerade as benign lesions resulting in delay of diagnosis. Early recognition is even more difficult in young patients where the disease rarely occurs. Here, we provide a clinicopathological correlation of ocular sebaceous carcinoma in a young individual lacking history of hereditary cancer or immunosuppression. Findings A detailed histopathological study including p53 DNA sequencing was performed on an aggressive sebaceous carcinoma presenting in a healthy 32 year-old Caucasian woman. She had no history of retinoblastoma, evidence for a hereditary cancer syndrome, or radiation therapy. However, she potentially was at risk for excessive UV light exposure. A detailed review of the literature is also provided. A moderately well differentiated sebaceous carcinoma was established histopathologically arising from the meibomian gland of the upper eyelid. In most areas, the cytoplasm contained small but distinct Oil-red-O positive vacuoles. Direct sequencing of p53 identified a G:C→A:T mutation at a dipyrimidine site. The mutation results in substitution of arginine for the highly conserved glycine at residue 199 located at the p53 dimer-dimer interface. Energy minimization structural modeling predicts that G199R will neutralize negative charges contributed by nearby inter- and intramonomeric glutamate residues. Discussion This study points to the importance of recognizing that sebaceous carcinoma can occur in young patients with no evidence for hereditary cancer risk or radiation therapy. The G199R substitution is anticipated to alter the stability of the p53 tetrameric complex. The role of UV light in the etiology of sebaceous carcinoma deserves further study. Our findings, taken together with those of others, suggest that different environmental factors could lead to the development of sebaceous carcinoma in different patients.

    Bipolar disorder is a recurrent disorder that affects more than 1% of the world population and usually has its onset during youth. Its chronic course is associated with high rates of morbidity and mortality, making bipolar disorder one of the main causes of disability among young and working-age people. The implementation of early intervention strategies may help to change the outcome of the illness and avert potentially irreversible harm to patients with bipolar disorder, as early phases may be more responsive to treatment and may need less aggressive therapies. Early intervention in bipolar disorder is gaining momentum. Current evidence emerging from longitudinal studies indicates that parental early-onset bipolar disorder is the most consistent risk factor for bipolar disorder. Longitudinal studies also indicate that a full-blown manic episode is often preceded by a variety of prodromal symptoms, particularly subsyndromal manic symptoms, therefore supporting the existence of an at-risk state in bipolar disorder that could be targeted through early intervention. There are also identifiable risk factors that influence the course of bipolar disorder, some of them potentially modifiable. Valid biomarkers or diagnosis tools to help clinicians identify individuals at high risk of conversion to bipolar disorder are still lacking, although there are some promising early results. Pending more solid evidence on the best treatment strategy in early phases of bipolar disorder, physicians should carefully weigh the risks and benefits of each intervention. Further studies will provide the evidence needed to finish shaping the concept of early intervention.

    Healthy brain development takes place within the context of individual experience. Here, we describe how certain early experiences are necessary for typical brain development. We present evidence from multiple studies showing that severe early life neglect leads to alterations in brain development, which compromises emotional, behavioral, and cognitive functioning. We also show how early intervention can reverse some of the deleterious effects of neglect on brain development. We conclude by emphasizing that early interventions that start at the earliest possible point in human development are most likely to support maximal recovery from early adverse experiences.

    There is an increasing awareness on the importance in identifying early phases of the degenerative processes in knee osteoarthritis (OA), the crucial period of the disease when there might still be the possibility to initiate treatments preventing its progression. Early OA may show a diffuse and ill-defined involvement, but also originate in the cartilage surrounding a focal lesion, thus necessitating a separate assessment of these two entities. Early OA can be considered to include a maximal involvement of 50 % of the cartilage thickness based on the macroscopic ICRS classification, reflecting an OARSI grade 4. The purpose of this paper was to provide an updated review of the current status of the diagnosis and definition of early knee OA, including the clinical, radiographical, histological, MRI, and arthroscopic definitions and biomarkers. Based on current evidence, practical classification criteria are presented. As new insights and technologies become available, they will further evolve to better define and treat early knee OA.

  19. Early diagnosis and early intervention in cerebral palsy

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available This paper reviews the opportunities and challenges for early diagnosis and early intervention in cerebral palsy (CP. CP describes a group of disorders of the development of movement and posture, causing activity limitation, that are attributed to disturbances that occurred in the fetal or infant brain. Therefore the paper starts with a summary of relevant information from developmental neuroscience. Most lesions underlying CP occur in the second half of gestation, when developmental activity in the brain reaches its summit. Variations in timing of the damage not only result in different lesions, but also in different neuroplastic reactions and different associated neuropathologies. This turns CP into a heterogeneous entity. This may mean that the best early diagnostics and the best intervention methods may differ for various subgroups of children with CP. Next, the paper addresses possibilities for early diagnosis. It discusses the predictive value of neuromotor and neurological exams, neuro-imaging techniques and neurophysiological assessments. Prediction is best when complementary techniques are used in longitudinal series. Possibilities for early prediction of CP differ for infants admitted to neonatal intensive care and other infants. In the former group best prediction is achieved with the combination of neuro-imaging and the assessment of general movements, in the latter group best prediction is based on carefully documented milestones and neurological assessment. The last part reviews early intervention in infants developing CP. Most knowledge on early intervention is based on studies in high risk infants without CP. In these infants early intervention programs promote cognitive development until preschool age; motor development profits less. The few studies on early intervention in infants developing CP suggest that programs that stimulate all aspects of infant development by means of family coaching are most promising. More research is

    The overall objective of this project is the three phase development of an Early Entrance Coproduction Plant (EECP) which uses petroleum coke to produce at least one product from at least two of the following three categories: (1) electric power (or heat), (2) fuels, and (3) chemicals using ChevronTexaco's proprietary gasification technology. The objective of Phase I is to determine the feasibility and define the concept for the EECP located at a specific site; develop a Research, Development, and Testing (RD&T) Plan to mitigate technical risks and barriers; and prepare a Preliminary Project Financing Plan. The objective of Phase II is to implement the work as outlined in the Phase I RD&T Plan to enhance the development and commercial acceptance of coproduction technology. The objective of Phase III is to develop an engineering design package and a financing and testing plan for an EECP located at a specific site. The project's intended result is to provide the necessary technical, economic, and environmental information needed by industry to move the EECP forward to detailed design, construction, and operation. The partners in this project are Texaco Energy Systems LLC or TES (a subsidiary of ChevronTexaco), General Electric (GE), Praxair, and Kellogg Brown & Root (KBR) in addition to the U.S. Department of Energy (DOE). TES is providing gasification technology and Fischer-Tropsch (F-T) technology developed by Rentech, Inc., GE is providing combustion turbine technology, Praxair is providing air separation technology, and KBR is providing engineering. During Phase I, a design basis for the Fischer-Tropsch Synthesis section was developed based on limited experience with the specified feed gas and operating conditions. The objective of this Task in Phase II RD&T work was to confirm the performance of the F-T reactor at the set design conditions.

    In 1999, the U. S. Department of Energy (DOE) awarded a Cooperative Agreement to Texaco Energy Systems Inc. to provide a preliminary engineering design of an Early Entrance Coproduction Plant (EECP). Since the award, continuous and diligent work has been undertaken to achieve the design of an economical facility that makes strides toward attaining the goal of DOE's Vision 21 Program. The objective of the EECP is to convert coal and/or petroleum coke to power while coproducing transportation fuels, chemicals, and useful utilities such as steam. This objective is being pursued in a three-phase effort through the partnership of the DOE with prime contractor Texaco Energy Systems, LLC. (TES), the successor to Texaco Energy Systems, Inc. The key subcontractors to TES include General Electric (GE), Praxair, and Kellogg Brown and Root. ChevronTexaco provided gasification technology and Rentech Inc.'s Fischer-Tropsch (F-T) technology that has been developed for non-natural gas sources. GE provided gas turbine technology for the combustion of low energy content gas. Praxair provided air separation technology and KBR provided engineering to integrate the facility. A conceptual design was completed in Phase I and the report was accepted by the DOE in May 2001. The Phase I work identified risks and critical research, development, and testing that would improve the probability of technical success of the EECP. The objective of Phase II was to mitigate the risks by executing research, development, and testing. Results from the Phase II work are the subject of this report. As the work of Phase II concluded, it became evident that sufficient, but not necessarily complete, technical information and data would be available to begin Phase III - Preliminary Engineering Design. Work in Phase II requires additional technical development work to correctly apply technology at a specific site. The project's intended result is to provide the necessary technical, economic, and

    Nuclear accidents are unexpected events characterized by losing of control over the sources of radiation. This may, directly or indirectly, create a danger to human life, health or property. In certain nuclear accidents, such dangers may be of a limited scope, which means that they constitute a threat only to those persons who work directly with the sources of radiation, or the equipment that comprises such sources, and their immediate working environment. Under certain conditions, as a consequence of major nuclear accidents, the broader population and considerable property might be endangered as well. The way in which nuclear accidents with the sources of ionizing radiation may occur, the intensity of doses that may exist in the radiation source environment, the nature and quantities of radioactive materials which might spread in the environment, the level of radiation exposure of the staff and the population due to a nuclear accident - all these may be considerably different in case of a nuclear accident with different radiation sources. Depending on the category of nuclear accident, major environmental pollutant releases are possible in such situations. The proposal for the establishment of a network of early notification monitors in the Republic of Croatia leans upon: a description of similar networks in Europe, the experience gathered during previous work with the existing monitors on the territory of the Republic of Slovenia, and direct experience of the three continuous radiological monitors established on the territory of the Republic of Croatia ('Rudjer Boskovic' Institute, Sljeme-Puntijarka and Velebit-Pljesivica). In this moment there are eight monitors MFM-202 installed on the territory of the Republic of Croatia, which are used to measure the dose rate. The position of eight monitors MFM-202 on the territory of the Republic of Croatia is displayed in MAP 1.

    Staff in the surgical intensive care unit (SICU) had several concerns about mobilizing patients receiving mechanical ventilation. To assess and improve the mindset of SICU staff toward early mobilization of patients receiving mechanical ventilation before, 6 months after, and 1 year after implementation of early mobilization. The Plan-Do-Study-Act model was used to guide the planning, implementation, evaluation, and interventions to change the mindset and practice of SICU staff in mobilizing patients receiving mechanical ventilation. Interventions to overcome barriers to early mobilization included interdisciplinary collaboration, multimodal education, and operational changes. The mindset of the SICU staff toward early mobilization of patients receiving mechanical ventilation was assessed by using a survey questionnaire distributed 2 weeks before, 6 months after, and 1 year after implementation of early mobilization. The median score on 6 of 7 survey questions changed significantly from before, to 6 months after, to 1 year after implementation, indicating a change in the mindset of SICU staff toward early mobilization of patients receiving mechanical ventilation. The SICU staff agreed that most patients receiving mechanical ventilation are able to get out of bed safely with coordination among personnel and that early mobilization of intubated patients decreases length of stay and decreases occurrence of ventilator-associated pneumonia, deep vein thrombosis, and skin breakdown. SICU interdisciplinary team collaboration, multimodal education, and operational support contribute to removing staff bias against mobilizing patients receiving mechanical ventilation. ©2015 American Association of Critical-Care Nurses.

    Full Text Available The question whether visual perception is spontaneous, sudden or is running through several phases, mediated by higher cognitive processes, was raised ever since the early work of Gestalt psychologists. In the early 1980s, Treisman proposed the feature integration theory of attention (FIT, based on the findings of neuroscience. Soon after publishing her theory a new scientific approach appeared investigating several visual perception phenomena. The most widely researched were the key constructs of FIT, like types of visual search and the role of the attention.

    The overall objective of this project is the three phase development of an Early Entrance Coproduction Plant (EECP) which uses petroleum coke to produce at least one product from at least two of the following three categories: (1) electric power (or heat), (2) fuels, and (3) chemicals using ChevronTexaco's proprietary gasification technology. The objective of Phase I is to determine the feasibility and define the concept for the EECP located at a specific site; develop a Research, Development, and Testing (RD&T) Plan to mitigate technical risks and barriers; and prepare a Preliminary Project Financing Plan. The objective of Phase II is to implement the work as outlined in the Phase I RD&T Plan to enhance the development and commercial acceptance of coproduction technology. The objective of Phase III is to develop an engineering design package and a financing and testing plan for an EECP located at a specific site. The project's intended result is to provide the necessary technical, economic, and environmental information needed by industry to move the EECP forward to detailed design, construction, and operation. The partners in this project are Texaco Energy Systems LLC or TES (a subsidiary of ChevronTexaco), General Electric (GE), Praxair, and Kellogg Brown & Root (KBR) in addition to the U.S. Department of Energy (DOE). TES is providing gasification technology and Fischer-Tropsch (F-T) technology developed by Rentech, GE is providing combustion turbine technology, Praxair is providing air separation technology, and KBR is providing engineering. Each of the EECP subsystems was assessed for technical risks and barriers. A plan was developed to mitigate the identified risks (Phase II RD&T Plan, October 2000). Phase II RD&T Task 2.6 identified as potential technical risks to the EECP the fuel/engine performance and emissions of the F-T diesel fuel products. Hydrotreating the neat F-T diesel product reduces potentially reactive olefins, oxygenates, and acids

    2012-12-01

    The Early Career Fellowship program was established in 2005 to facilitate the integration of outstanding early career planetary science researchers into established research funding programs by providing tools and experience useful to maintain a successful research program. Executing a successful research program requires a few key elements such as: successful proposal writing; adequate (paid) research time; management of a laboratory; collaboration and networking; frequent and high-quality publications; and adequate start-up equipment funds. These elements may be particularly critical for early career researchers searching for a tenure- track or equivalent position. The Early Career Fellowship program recognizes the importance of these skills and provides extra funding and resources to begin a successful research program. For consideration into The Early Career Fellowship program, the candidate needs to be the P. I. or Science P.I. of a funded research proposal from one of the participating R&A program areas, be within 7 years of earning a PhD, hold a non-tenure track position, and indicate the early career candidacy when submitting the research proposal. If the research proposal is funded and the discipline scientist nominates the candidate as an early career fellow, the candidate is then considered a Fellow and eligible to propose for Step 2. Upon obtaining a tenure-track equivalent position the Fellow submits a Step 2 proposal for up to one hundred thousand dollars in start-up funds. Start-up funds may be used for salary; undergraduate and/or graduate research assistants; supplies and instrument upgrades; travel to conferences, meetings, and advisory groups; time and travel for learning new skills; publication page charges; books and journal subscriptions; computer time and/or specialized software; and other justified research-specific needs. The early career fellowship program provides resources that a more established scientist would have acquired allowing

  18. Epigenetics of Early Child Development

    Full Text Available Comprehensive clinical studies show that adverse conditions in early life can severely impact the developing brain and increase vulnerability to mood disorders later in life. During early postnatal life the brain exhibits high plasticity which allows environmental signals to alter the trajectories of rapidly developing circuits. Adversity in early life is able to shape the experience-dependent maturation of stress-regulating pathways underlying emotional functions and endocrine responses to stress, such as the hypothalamo-pituitary-adrenal (HPA system, leading to long-lasting altered stress responsivity during adulthood.To date, the study of gene-environment interactions in the human population has been dominated by epidemiology. However, recent research in the neuroscience field is now advancing clinical studies by addressing specifically the mechanisms by which gene-environment interactions can predispose individuals towards psychopathology. To this end, appropriate animal models are being developed in which early environmental factors can be manipulated in a controlled manner. Here we will review recent studies performed with the common aim of understanding the effects of the early environment in shaping brain development and discuss the newly developing role of epigenetic mechanisms in translating early life conditions into long-lasting changes in gene expression underpinning brain functions. Particularly, we argue that epigenetic mechanisms can mediate the gene-environment dialogue in early life and give rise to persistent epigenetic programming of adult physiology and dysfunction eventually resulting in disease. Understanding how early life experiences can give raise to lasting epigenetic memories conferring increased risk for mental disorders, how they are maintained and how they could be reversed, is increasingly becoming a focus of modern psychiatry and should pave new guidelines for timely therapeutic interventions.

    2017-04-01

    With approximately 67 million individuals affected worldwide, autism spectrum disorder (ASD) is the fastest growing neurodevelopmental disorder (United Nations, 2011), with a prevalence estimated to be 1/100. In France ASD affects approximately 600,000 individuals (from childhood to adulthood, half of whom are also mentally retarded), who thus have a major handicap in communication and in adapting to daily life, which leads autism to be recognized as a national public health priority. ASD is a neurodevelopmental disorder that affects several domains (i.e., socio-emotional, language, sensori-motor, executive functioning). These disorders are expressed early in life with an age of onset around 18 months. Despite evidence suggesting a strong genetic link with ASD, the genetic determinant remains unclear. The clinical picture is characterized by impairments in social interaction and communication and the presence of restrictive and repetitive behaviors (DSM-5, ICD-10). However, in addition to these two main dimensions there is significant comorbidity between ASD and other neurodevelopmental disorders such as attention deficit hyperactivity disorder or with genetic and medical conditions. One of the diagnostic features of ASD is its early emergence: symptoms must begin in early childhood for a diagnosis to be given. Due to brain plasticity, early interventions are essential to facilitate clinical improvement. Therefore, general practitioners and pediatricians are on the front line to detect early signs of ASD and to guide both medical explorations and early rehabilitation.

  20. The early evolution of rhynchosaurs

    Directory of Open Access Journals (Sweden)

    Martin Daniel Ezcurra

    2016-01-01

    Full Text Available The rhynchosaurian archosauromorphs are an important and diverse group of fossil tetrapods that first appeared during the Early Triassic and probably became extinct during the early Late Triassic (early Norian. Here, the early evolution of rhynchosaurs during the Early and early Middle Triassic (Induan−Anisian: 252.2−242 Mya is reviewed based on new anatomical observations and the implications of these observations for the taxonomy, phylogenetic relationships and macroevolutionary history of the group. A quantitative phylogenetic analysis recovered a paraphyletic genus Rhynchosaurus, with Rhynchosaurus brodiei more closely related to hyperodapedontines than to Rhynchosaurus articeps. Therefore, a new genus is erected, resulting in the new combination Langeronyx brodiei. A body size analysis found two independent increases in size in the evolutionary history of rhynchosaurs, one among stenaulorhynchines and the other in the hyperodapedontine lineage. Maximum likelihood fitting of phenotypic evolution models to body size data found ambiguous results, with body size evolution potentially interpreted as either fitting either a non-directional Brownian motion model or a stasis model. A Dispersal−Extinction−Cladogenesis analysis reconstructed the areas that are now South Africa and Europe as the ancestral areas of Rhynchosauria and Rhynchosauridae, respectively. The reconstruction of dispersal events between geographic areas that are broadly separated paleolatitudinally implies that barriers to the dispersal of rhynchosaurs from either side of the paleo-Equator during the Middle Triassic were either absent or permeable.

However, its chronic use may be associated to severe side effects which may be worsened by anesthetic-surgical acts, thus increasing the risk of such procedures. This study aimed at reviewing major amiodarone effects and relating them to anesthetic procedures. CONTENTS: The study covers major amiodarone properties, its clinical use, as well as major adverse effects, which may increase patient's surgical risk. CONCLUSIONS: Amiodarone, although normally safe and effective, may present adverse effects, especially on cardiovascular system, during anesthetic-surgical procedures. This is possibly due to interactions between this drug and anesthetic agents mainly related to general anesthesia. There are reports on severe, treatment - resistant bradycardias as well as on different degrees of atrioventricular block (AVB. Patients should be carefully monitored, especially during major procedures, and vasoactive drugs (isoproterenol and temporary artificial pacemaker, should be available because they may be critical during the adverse effects treatment.

    Obese patients are at increased risk for hypoventilation, leading to hypercapnea and acidosis. The primary objective of this study was to compare the incidence of perioperative hypercapnea in non-obese and morbidly obese patients using the SenTec transcutaneous PCO2 (tcPCO2) monitor. 10 morbidly obese subjects (BMI > 40 kg/m(2)) undergoing laparoscopic bariatric surgery, and 10 non-obese subjects (BMI TcPCO2 and SpO2 were monitored continuously intraoperatively, and during the first 24 h postoperatively. Opiate consumption, respiratory rate (RR), and pain scores were collected from postanesthesia care unit (PACU) and ward nursing notes. RR, SpO2, and tcPCO2 did not differ significantly between groups during PACU or ward time periods. End-tidal CO2 (EtCO2) values were similar between groups during the intraoperative period, but tcPCO2 was significantly higher in the obese group at specific time points, and trended towards being higher throughout the case. Our study did not show significant tcPCO2 differences between non-obese and obese post-surgical patients, however, it did allow for continuous, trendable, nonobtrusive monitoring throughout the perioperative period. As V/Q mismatch increases with the PaCO2/EtCO2 gradient, and this effect is most pronounced in morbidly obese patients, tcPCO2 monitoring may prove to be a useful additional monitor in these patients during the intraoperative period.

    Non-cardiac surgery is associated with major vascular complications and higher incidences of elevated plasma troponin (cTn) concentration. Goal-directed therapy (GDT) is a stroke volume (SV)-guided approach to intravenous (IV) fluid therapy that improves tissue perfusion, oxygenation and reduces post-operative complications. In patients undergoing major gastro-intestinal surgery, we compared high sensitive and contemporary troponin assays and correlated results with patient outcome.

  9. EARLY COMPLICATIONS IN BARIATRIC SURGERY:

    Directory of Open Access Journals (Sweden)

    Marco Aurelio SANTO

    Full Text Available ContextBariatric surgery has proven to be the most effective method of treating severe obesity. Nevertheless, the acceptance of bariatric surgery is still questioned. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control.MethodThe medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery were reviewed. Ninety-three (17.2% patients were male and 445 (82.8% were female. The ages of the patients ranged from 18 to 70 years (average = 46, and their body mass indices ranged from 34.6 to 77 kg/m2.ResultsEarly complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. Three (0.5% patients experienced pulmonary thromboembolism. The mortality rate was 0,55%.ConclusionThe incidence of early complications was low. The diagnosis of these complications was mostly clinical, based on the presence of signs and symptoms. The value of the clinical signs and early treatment, specially in cases of sepsis, were essential to the favorable surgical outcome. The mortality was mainly related to thromboembolism and advanced age, over 65 years.

    2003-04-01

    Popular hypotheses that attempt to explain the origin of prebiotic molecules and cellular life capable of growth and division are not always agreed upon. In this manuscript, information on early bacterial life on Earth is examined using information from several disciplines. For example, knowledge can be integrated from physics, thermodynamics, planetary sciences, geology, biogeochemistry, lipid chemistry, primordial cell structures, cell and molecular biology, microbiology, metabolism and genetics. The origin of life also required a combination of elements, compounds and environmental physical-chemical conditions that allowed cells to assemble in less than a billion years. This may have been widespread in the subsurface of the early Earth located at microscopic physical domains.

    We point out a surprising consequence of the usually assumed initial conditions for cosmological perturbations. Namely, a spectrum of Gaussian, linear, adiabatic, scalar, growing mode perturbations not only creates acoustic oscillations of the kind observed on very large scales today, it also leads to the production of shocks in the radiation fluid of the very early Universe. Shocks cause departures from local thermal equilibrium as well as create vorticity and gravitational waves. For a scale-invariant spectrum and standard model physics, shocks form for temperatures 1  GeVUniverse as early as 10^{-30}  sec after the big bang.

  13. Istanbul Earthquake Early Warning System

    2007-12-01

    As part of the preparations for the future earthquake in Istanbul a Rapid Response and Early Warning system in the metropolitan area is in operation. For the Early Warning system ten strong motion stations were installed as close as possible to the fault zone. Continuous on-line data from these stations via digital radio modem provide early warning for potentially disastrous earthquakes. Considering the complexity of fault rupture and the short fault distances involved, a simple and robust Early Warning algorithm, based on the exceedance of specified threshold time domain amplitude levels is implemented. The band-pass filtered accelerations and the cumulative absolute velocity (CAV) are compared with specified threshold levels. When any acceleration or CAV (on any channel) in a given station exceeds specific threshold values it is considered a vote. Whenever we have 2 station votes within selectable time interval, after the first vote, the first alarm is declared. In order to specify the appropriate threshold levels a data set of near field strong ground motions records form Turkey and the world has been analyzed. Correlations among these thresholds in terms of the epicenter distance the magnitude of the earthquake have been studied. The encrypted early warning signals will be communicated to the respective end users. Depending on the location of the earthquake (initiation of fault rupture) and the recipient facility the alarm time can be as high as about 8s. The first users of the early warning signal will be the Istanbul gas company (IGDAS) and the metro line using the immersed tube tunnel (MARMARAY). Other prospective users are power plants and power distribution systems, nuclear research facilities, critical chemical factories, petroleum facilities and high-rise buildings. In this study, different algorithms based on PGA, CAV and various definitions of instrumental intensity will be discussed and triggering threshold levels of these parameters will be studied

  13. Famines in Africa: is early warning early enough?

    2012-06-01

    Full Text Available Following the second Sahelian famine in 1984–1985, major investments were made to establish Early Warning Systems. These systems help to ensure that timely warnings and vulnerability information are available to decision makers to anticipate and avert food crises. In the recent crisis in the Horn of Africa, alarming levels of acute malnutrition were documented from March 2010, and by August 2010, an impending food crisis was forecast. Despite these measures, the situation remained unrecognised, and further deteriorated causing malnutrition levels to grow in severity and scope. By the time the United Nations officially declared famine on 20 July 2011, and the humanitarian community sluggishly went into response mode, levels of malnutrition and mortality exceeded catastrophic levels. At this time, an estimated 11 million people were in desperate and immediate need for food. With warnings of food crises in the Sahel, South Sudan, and forecast of the drought returning to the Horn, there is an immediate need to institutionalize change in the health response during humanitarian emergencies. Early warning systems are only effective if they trigger an early response.

  14. Pompe Disease: Early Diagnosis and Early Treatment Make a Difference

    Full Text Available Pompe disease (glycogen storage disease type II or acid maltase deficiency is a lysosomal disorder in which acid α-glucosidase (GAA deficiencies lead to intralysosomal accumulation of glycogen in all tissues; most notably in skeletal muscles. Both the patient's age at the onset of Pompe disease symptoms and the rate of deterioration caused by the disease can vary considerably. In classical infant-onset Pompe disease (IOPD, symptoms start very early in life, and death occurs soon afterward if the disease remains untreated. In later-onset Pompe disease, symptoms are slower to appear, and patients often progress to wheelchair confinement and eventual respiratory failure. A diagnosis can be made by screening for GAA in dried blood samples, followed either by GAA assessment in lymphocytes or in fibroblasts or by the genetic analysis of mutations. Treatment by enzyme replacement therapy (ERT with alglucosidase alfa was approved for human use in 2006. In classical IOPD, treatment significantly lengthens survival and improves motor development and cardiac function. The sooner ERT begins, the better are the results. Newborn screening aims to take advantage of different technologies for diagnosing and treating newborns early on and it yields better outcomes. However, newborns diagnosed early and other long-term survivors may encounter fresh problems, making up a new phenotype of IOPD patients. Further modifications of the treatment, such as a decrease in immune responses to ERT, a higher dosage, a better uptake formulation, and gene therapy delivered locally or systemically are being explored.

    There is significant evidence for an involvement of reactive oxygen species (ROS) in the pathogenesis of diabetic vascular complications through many metabolic and structural derangements. However, despite the advanced knowledge on the crucial role of ROS in cardiovascular damage, their intracellular source in endothelial cells exposed to high concentrations of glucose has not been precisely defined. Moreover, the molecular mechanism of action of elevated glucose on mitochondria has not been fully elucidated. The main aim of this study was to describe changes in the mitochondrial metabolism of human umbilical vein endothelial cells (HUVECs) treated with high glucose concentrations and to indicate the actual source of ROS in these cells. HUVECs exposed to 30 mM glucose exhibited an increased content of vascular adhesive molecule-1 (VCAM-1) and an excessive ROS production. Faster oxygen consumption and increased abundance of selected respiratory complexes coexist with slightly declined mitochondrial membrane potential and substantially elevated amount of uncoupling protein-2 (UCP2). Inhibition of NADPH oxidase (NOX) and modification of mitochondrial ROS generation with a mitochondrial uncoupler or respiratory chain inhibitors allowed concluding that the major source of ROS in HUVECs exposed to hyperglycaemic conditions is NOX. The mitochondrial respiratory chain seems not to participate in this phenomenon. Copyright © 2013 Elsevier Inc. All rights reserved.

    Diabetes mellitus (DM) is a constant and illimitable metabolic disorder that can happen even at a young age due to the virtual absence of naturally acting insulin, which uptakes and accumulates glucose; thereby reduce the use of glucose. In the present study, we evaluated the neuroprotective efficacy of andrographolide on streptozotocin (STZ) induced diabetic Sprague dawley rats. Diabetes was induced by intraperitonial injection of STZ (45 mg/kg B.W) in Sprague dawley rats. Andrographolide (2.5 mg/kg B.W) was administered orally to diabetic rats and Glibenclamide (25mg/kg B.W) as control for 30 days to assess its effects on blood glucose, insulin, insulin resistance and antioxidant profiles such as superoxide dismutase, catalase, glutathione peroxidase, reduced glutathione and lipid peroxidation in various regions of brain namely hypothalamus, cerebellum, hippocampus and brain cerebral cortex. Oral supplementation of andrographolide extensively diminished the blood glucose levels than diabetic control. There was noteworthy reduction in the CAT, SOD and GPx activities in the hippocampus, hypothalamus and cerebral cortex cerebellum of the DM rat brain. However, andrographolide supplementation drastically reverses the CAT, GPx and SOD back to normal levels. In conclusion, the results revealed that andrographolide shown beneficial potentiality against neuropathy in STZ induced diabetic rats.

    Full Text Available Abstract Background There is increasing evidence that tight blood glucose (BG control improves outcomes in critically ill adults. Children show similar hyperglycaemic responses to surgery or critical illness. However it is not known whether tight control will benefit children given maturational differences and different disease spectrum. Methods/Design The study is an randomised open trial with two parallel groups to assess whether, for children undergoing intensive care in the UK aged ≤ 16 years who are ventilated, have an arterial line in-situ and are receiving vasoactive support following injury, major surgery or in association with critical illness in whom it is anticipated such treatment will be required to continue for at least 12 hours, tight control will increase the numbers of days alive and free of mechanical ventilation at 30 days, and lead to improvement in a range of complications associated with intensive care treatment and be cost effective. Children in the tight control group will receive insulin by intravenous infusion titrated to maintain BG between 4 and 7.0 mmol/l. Children in the control group will be treated according to a standard current approach to BG management. Children will be followed up to determine vital status and healthcare resources usage between discharge and 12 months post-randomisation. Information regarding overall health status, global neurological outcome, attention and behavioural status will be sought from a subgroup with traumatic brain injury (TBI. A difference of 2 days in the number of ventilator-free days within the first 30 days post-randomisation is considered clinically important. Conservatively assuming a standard deviation of a week across both trial arms, a type I error of 1% (2-sided test, and allowing for non-compliance, a total sample size of 1000 patients would have 90% power to detect this difference. To detect effect differences between cardiac and non-cardiac patients, a target sample size of 1500 is required. An economic evaluation will assess whether the costs of achieving tight BG control are justified by subsequent reductions in hospitalisation costs. Discussion The relevance of tight glycaemic control in this population needs to be assessed formally before being accepted into standard practice.

    Reactive oxygen species play a significant role in the pathogenesis of retinopathy in diabetes patients. The current study aimed to assess the effect of ethyl acetate extract (EAE) from Balanites aegyptiaca (10, 25 or 50 mg/kg b.w.) in experimental diabetic rats. To achieve this aim, five groups of male rats were included: control, diabetic, and diabetic rats treated with 10, 25, and 50 µg/kg b.w. of EAE for eight weeks. Our results suggests a protective role of EAE against oxidative stress induced by streptozocine. EAE treatment produced a reduction in blood glucose levels, HbA1c, malondialdehyde and vascular endothelial growth factor (VEGF) in diabetic retina (p < 0.001), as well as an enhancement in antioxidant capacity against streptozocine-induced oxidative stress. Tumor necrosis factor alpha (TNF-α), interleukin (IL-1β) and vascular endothelial growth factor (VEGF) were significantly reduced in diabetic rats treated with EAE, compared with untreated diabetic rats. Analysis of EAE by GC-MS indicated the presence of β-sistosterol. Overall, EAE modulates oxidative stress induced by streptozocine and enhances antioxidant activity, which may provide additional endothelial protection in retina of diabetic rats. These results hold great promise in the management of diabetic complications.

    Exposure to unnatural light cycles is increasingly associated with obesity and the metabolic syndrome. The purpose of this study was to examine the effects of electroacupuncture (EA) on glucose metabolism and ovarian function in female rats subjected to long-term continuous light exposure. Female Sprague-Dawley rats (n=24) were divided into three experimental groups: an LD group that was maintained under a normal light-dark cycle (healthy control); an LL group that was exposed to continuous light for 21 weeks but remained untreated; and an LL+EA group that received EA at ST36 and SP6 during weeks 17 to 21 of continuous light exposure. Oestrous cycles of female rats kept in a continuously lit environment for 21 weeks were disordered and polycystic ovarian syndrome (PCOS)-like changes occurred, accompanied by increased fasting blood glucose (6.23±0.33 vs 5.27±0.40 mmol/L in week 17, p=0.015) and reduced fasting levels of serum testosterone (0.07±0.018 vs 0.12±0.058 ng/L, p=0.043) and insulin (0.89±0.20 vs 1.43±0.46 ng/L, p=0.006). After 5 weeks of EA treatment at ST36 and SP6, ovarian cycle disruption was mitigated and blood glucose levels showed a gradual decline (5.18±0.37 vs 5.80±0.55 mmol/L, p=0.017; and 5.73±0.31 vs 6.62±0.13 mmol/L, p=0.004; in the fourth and fifth weeks of EA treatment, respectively). EA also attenuated the reductions otherwise seen in serum insulin and testosterone levels. Prolonged exposure to light can lead to a decline in ovarian and pancreatic function. EA at ST36 and SP6 may reduce abnormally elevated blood glucose levels and improve ovarian and pancreatic hormone levels. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  8. Osteoporosis and its association with non-gonadal hormones involved in hypertension, adiposity and hyperglycaemia.

    Poudyal, Hemant; Brown, Lindsay

    2013-12-01

    Osteoporosis is a high-prevalence disease, particularly in developed countries, and results in high costs both to the individual and to society through associated fragility fractures. There is an urgent need for identification of novel drug targets and development of new anti-osteoporotic agents. Between 30 and 80% of osteoporotic fractures cannot be prevented despite current treatments achieving relative fracture risk reduction of up to 20%, 50%, and 70% for non-vertebral, hip and spine fractures, respectively. Traditionally, the decline in gonadal hormones has been studied as the sole hormonal determinant for the loss of bone mineral density in osteoporosis. However, recent studies have identified receptors for numerous non-gonadal hormones such as PTH, angiotensin II, leptin, adiponectin, insulin and insulin-like growth factor-1 on the osteoblast lineage cells that directly regulate bone turnover. These hormones are also involved in the pathogenesis of metabolic syndrome risk factors, particularly hypertension, type-II diabetes and obesity. By activating their respective receptors on osteoblastic lineage cells, these hormones appear to act through a common mechanism by down-regulating receptors for activation of nuclear factor kappa B ligand (RANKL) and up-regulating osteoprotegerin (OPG) with inverse responses for adiponectin. Receptors for amylin, gastric inhibitory polypeptide and ghrelin and have also been identified on the osteoblast lineage cells although the roles of these receptors in bone turnover are controversial or poorly studied. Moreover, bone turnover may be independently regulated by modulation of osteoclast-osteoblast function and bone marrow adiposity. Leptin appears to be the only hormone that is a known regulator of both bone mineralisation and bone adiposity.

    Full Text Available Abstract Background Zebrafish (D. rerio has become a powerful and widely used model system for the analysis of vertebrate embryogenesis and organ development. While genetic methods are readily available in zebrafish, protocols for two dimensional (2D gel electrophoresis and proteomics have yet to be developed. Results As a prerequisite to carry out proteomic experiments with early zebrafish embryos, we developed a method to efficiently remove the yolk from large batches of embryos. This method enabled high resolution 2D gel electrophoresis and improved Western blotting considerably. Here, we provide detailed protocols for proteomics in zebrafish from sample preparation to mass spectrometry (MS, including a comparison of databases for MS identification of zebrafish proteins. Conclusion The provided protocols for proteomic analysis of early embryos enable research to be taken in novel directions in embryogenesis.

  10. Early stages of Ostwald ripening

    Shneidman, Vitaly A.

    2013-07-01

    The Becker-Döring (BD) nucleation equation is known to predict a narrow double-exponential front (DEF) in the distribution of growing particles over sizes, which is due to early transient effects. When mass conservation is included, nucleation is eventually exhausted while independent growth is replaced by ripening. Despite the enormous difference in the associated time scales, and the resulting demand on numerics, within the generalized BD model the early DEF is shown to be crucial for the selection of the unique self-similar Lifshitz-Slyozov-Wagner asymptotic regime. Being preserved till the latest stages of growth, the DEF provides a universal part of the initial conditions for the ripening problem, regardless of the mass exchange mechanism between the nucleus and the matrix.

    Full Text Available Vast numbers of studies and developments in the nanotechnology area have been conducted and many nanomaterials have been utilized to detect cancers at early stages. Nanomaterials have unique physical, optical and electrical properties that have proven to be very useful in sensing. Quantum dots, gold nanoparticles, magnetic nanoparticles, carbon nanotubes, gold nanowires and many other materials have been developed over the years, alongside the discovery of a wide range of biomarkers to lower the detection limit of cancer biomarkers. Proteins, antibody fragments, DNA fragments, and RNA fragments are the base of cancer biomarkers and have been used as targets in cancer detection and monitoring. It is highly anticipated that in the near future, we might be able to detect cancer at a very early stage, providing a much higher chance of treatment.

    Early diagnosis is necessary if the prevalence of periodontal disease is to be brought under control. For periodontal screening in dental practice we propose to employ the C.P.I.T.N. system, combined with examination of two or four dental bite-wing radiographs. Both of these procedures can be accurately applied in general dental practice conditions. The screening is not time consuming and can yield very important diagnostic data.

  13. Supporting Families through Early Intervention

    Directory of Open Access Journals (Sweden)

    Roy McConkey

    2003-09-01

    Full Text Available Internationally early intervention programmes for infants and preschoolers with disabilities have proved to be remarkably successful. In many countries, they began with teachers for visually impaired or hearing impaired children visiting the family home to teach parents how they could overcome the child's impairments. The logic of early intervention was inequitable. For example, the sooner children with visual impairments learnt to be independently mobile, then the greater their potential to learn and to kad an ordinary life. In time, this philosophy was extended to children with neurological and developmental delays, such as mental retardation, although success could be variable. In part, many different factors contributed to this variability: the form the interventions took, the extent of family involvement in the intervention and the lack of sensitivity of the measures used to assess a child's progress, to name but three. Perhaps the most extensive and intensive Early intervention schemes have been in the United States with their Head Start programmes. They were aimed at promoting the educational potential of preschoolers from deprived socio - economic backgrounds. Although the first phase of programmes had varying success, those in the second phase yielded impressive results which were mainly attributed to a greater focus on parental participation and links forged with the school system. Recently in developing countries, priority has been given to establishing early intervention as a means of creating new styles of family-based and community-based service in these countries in contrast to the hospital or institutional-services that were a legacy from a previous generation. Although formal evaluations are largely lacking, informal reports have been broadly enthusiastic. In sum, early intervention is no longer a new approach to developmental disabilities. It is an approach of proven effectiveness with children who have different impairments

    Thirteen billion years ago, early galaxies ionized the gas around them, producing some of the first light that brought our universe out of its dark ages. Now the Atacama Large Millimeter/submillimeter Array (ALMA) has provided one of the first detailed looks into the interior of one of these early, distant galaxies.Sources of LightArtists illustration of the reionization of the universe (time progresses left to right), in which ionized bubbles that form around the first sources of light eventually overlap to form the fully ionized universe we observe today. [Avi Loeb/Scientific American]For the first roughly hundred million years of its existence, our universe expanded in relative darkness there were no sources of light at that time besides the cosmic microwave background. But as mass started to condense to form the first objects, these objects eventually shone as the earliest luminous sources, contributing to the reionization of the universe.To learn about the early production of light in the universe, our best bet is to study in detail the earliest luminous sources stars, galaxies, or quasars that we can hunt down. One ideal target is the galaxy COSMOS Redshift 7, known as CR7 for short.Targeting CR7CR7 is one of the oldest, most distant galaxies known, lying at a redshift of z 6.6. Its discovery in 2015 and subsequent observations of bright, ultraviolet-emitting clumps within it have led to broad speculation about the source of its emission. Does this galaxy host an active nucleus? Or could it perhaps contain the long-theorized first generation of stars, metal-free Population III stars?To determine the nature of CR7 and the other early galaxies that contributed to reionization, we need to explore their gas and dust in detail a daunting task for such distant sources! Conveniently, this is a challenge that is now made possible by ALMAs incredible capabilities.

  20. Restraint Effects in Early Age Concrete Structures

    OpenAIRE

    Al-Gburi, Majid

    2015-01-01

    One of the widespread issues in concrete structures is cracks occurring at early age. Cracks that appear in the young concrete may cause early start of corrosion of rebars or early penetration of harmful liquids or gases into the concrete body. These situations could result in reduced service life and in significantly increased maintenance cost of structures. Therefore it is important for construction companies to avoid these cracks.Volumetric deformations in early age concrete are caused by ...

  1. Early diagnosis of the Spondyloarthropathies

    International Nuclear Information System (INIS)

    Gonzalez Naranjo, Luis Alonso; Londono, John D; Valle, Rafael Raul

    2005-01-01

    Spondyloarthropathies are a cluster of chronic inflammatory diseases that primarily include ankylosing spondylitis, reactive arthritis, psoriatic arthritis; arthritis associated with inflammatory bowel diseases and undifferentiated spondyloarthropathies. The most common subgroups of spondyloarthropathies are ankylosing spondylitis and undifferentiated spondyloarthropathy. The diagnosis of ankylosing spondylitis is mainly based on unequivocal radiographic sacroiliitis of at least grade 2 bilaterally or grade 3 unilaterally. How ever, in the early phase of disease, conventional radiographs are often too insensitive to show sacroiliitis and it usually takes several years for definite radiographic sacroiliitis to evolve. Thus, the diagnosis of ankylosing spondylitis is a commonly delayed by 8 to 11 years after the onset of symptoms. As a result, diagnosing axial spondyloarthropathy in the absence of radiographic sacroiliitis is very difficult to rheumatologists. In the early phase of disease, HLA B27 test and magnetic resonance imaging of sacroiliac joints may be helpful to the early diagnosis. In the presence of chronic low back pain the probability of axial spondyloarthropathy is about 5% and is about 14% if the back pain is inflammatory. The presence of = 3 features of spondyloarthropathy (heel pain, uveitis, dactylitis, positive family history, alternating buttock pain, psoriasis, inflammatory bowel disease, asymmetrical arthritis, positive response to anti-inflammatory drugs) increase the probability of axial spondyloarthropathy to 90%. Both, the positive HLA B27 and magnetic resonance imaging with signs of sacroiliitis increase the probability of spondyloarthropathy, particularly in patients without spondyloarthropathies features or with only 1 or 2 features. Since ankylosing spondylitis in association with psoriasis and inflammatory bowel disease is often HLA B27 negative, this test is of limited value under theses circumstances. Is important to consider that

    2015-01-01

    The article explores the extent to which the organization of vocational tracks in upper secondary school affects the labour market risks associated with early school exit. The Nordic countries share many features, but the upper secondary school systems differ significantly in how their vocational...... tracks are organized. Denmark and Norway have dual vocational tracks, that is, they combine school-based education and workplace apprenticeships, whereas in Finland and Sweden they are primarily school based. We analyse administrative longitudinal data from the mid-1990s to the mid-2000s in the four...

  3. Early detection of congenital syphilis

    2014-01-01

    Full Text Available Late congenital syphilis is a very rare clinical entity, and its early diagnosis and treatment is essential. Dental findings often provide valuable evidence for the diagnosis of late congenital syphilis. It occurs due to the transmission of the disease from an infected mother to her fetus through placenta. This long forgotten disease continues to effect pregnant women resulting in perinatal morbidity and mortality. Congenital syphilis is a preventable disease, and its presence reflects a failure of prenatal care delivery system, as well as syphilis control programs. We are reporting a case of late congenital syphilis with only Hutchinson′s teeth.

    2014-01-01

    Schizophrenia is often referred to as one of the most severe mental disorders, primarily because of the very high mortality rates of those with the disorder. This article reviews the literature on excess early mortality in persons with schizophrenia and suggests reasons for the high mortality...... as well as possible ways to reduce it. Persons with schizophrenia have an exceptionally short life expectancy. High mortality is found in all age groups, resulting in a life expectancy of approximately 20 years below that of the general population. Evidence suggests that persons with schizophrenia may...

  5. Early Detection of Ovarian Cancer

    Full Text Available Despite advances in therapy, ovarian cancer remains the most deadly of the gynecological cancers. Less than 30% of women with advanced stage disease survive long-term. When diagnosed in stage I, up to 90% of patients can be cured with conventional surgery and chemotherapy. At present, only 25% of ovarian cancers are detected in stage I due, in part, to the absence of specific symptoms and to lack of an effective screening strategy. Early detection of ovarian cancer might significantly improve the overall survival rate of women with ovarian cancer if 1 most cancers are clonal and unifocal, arising in the ovary rather than in the peritoneum, 2 metastatic disease results from progression of clinically detectable stage I lesions, and 3 cancers remain localized for a sufficient interval to permit cost-effective screening. Given the prevalence of ovarian cancer, strategies for early detection must have high sensitivity for early stage disease (> 75%, but must have extremely high specificity (99.6% to attain a positive predictive value of at least 10%. Transvaginal sonography (TVS, serum markers and a combination of the two modalities have been evaluated for early detection of ovarian cancer. Among the serum markers, CA125 has received the most attention, but lacks the sensitivity or specificity to function alone as a screening test. Greater specificity can be achieved by combining CA125 and TVS and/or by monitoring CA125 over time. Two stage screening strategies promise to be cost effective, where abnormal serum assays prompt TVS to detect lesions that require laparotomy. Accrual has been completed for a 200,000 woman trial in the United Kingdom that will test the ability of a rising CA125 to trigger TVS and subsequent exploratory surgery. Given the heterogeneity of ovarian cancer, it is unlikely that any single marker will be sufficiently sensitive to provide an effective initial screen. Sensitivity of serum assays might be enhanced by utilizing a

    Acute pancreatitis is the most common gastro-intestinal indication for acute hospitalization and its incidence continues to rise. In severe pancreatitis, morbidity and mortality remains high and is mainly driven by organ failure and infectious complications. Early management strategies should aim to prevent or treat organ failure and to reduce infectious complications. This review addresses the management of acute pancreatitis in the first hours to days after onset of symptoms, including fluid therapy, nutrition and endoscopic retrograde cholangiography. This review also discusses the recently revised Atlanta classification which provides new uniform terminology, thereby facilitating communication regarding severity and complications of pancreatitis.

    This invention provides an electronic proximity apparatus and a surveillance method using such an apparatus for alerting individuals that are exposed to a contagious disease. When a person becomes symptomatic and is diagnosed as positive for a given contagious agent, individuals that have recently maintained a threshold proximity with respect to an infected individual are notified and advised to seek immediate medial care. Treatment of individuals in the very early phases of infection (pre-symptomatic) significantly reduces contagiousness of the infected population first exposed to the contagious disease, thus preventing spread of the disease throughout the general population.

    Full Text Available This study was aimed to compare the peri-operative outcomes among the mitral valve replace-ment using anterolateral thoracotomy (n=17 and standard median sternotomy (n=17 in a single surgeons practice. The mean age was 24.1 ± 5.3 years in Group I and 41.0 ± 11.5 years in Group II. Female was predominant in Group I. Total operative time and bypass time were significant in both the study groups. Incision scar was not visible in females in Group I but full incision scar was visible in Group II in sitting posture. In Group I patients, majority (52.9% patients needed short duration of ICU stay in comparison to Group II, and the difference was statistically significant (p<0.05 between the two groups. During discharge, 94.1% wound was well healed in Group I and 70.6% in Group II. Wound dehiscence was nil in Group I, but 23.5% patients developed dehiscence in Group II. However, only 5.9% patient developed unstable sternum in Group II. Cosmetic mitral valve replacement can be done safely through anterolateral thoracotomy and it is cost effective especially for the developing countries.

    Scott, B.R.; Hahn, F.F.

    1985-01-01

    This chapter deals with health-risk estimates for early and continuing effects of exposure to ionizing radiations that could be associated with light water nuclear power plants accidents. Early and continuing effects considered are nonneoplastic diseases and symptoms that normally occur soon after radiation exposure, but may also occur after years have passed. They are generally associated with relatively high (greater than 1 Gy) doses. For most of the effects considered, there is a practical dose threshold. Organs of primary interest, because of their high sensitivity or the likelihood of receiving a large radiation dose, are bone marrow, gastrointestinal tract, thyroid glands, lungs, skin, gonads, and eyes. In utero exposure of the fetus is also considered. New data and modeling techniques available since publication of the Reactor Safety Study (WASH 1400, 1975) were used along with data cited in the Study to develop improved health-risk models for morbidity and mortality. The new models are applicable to a broader range of accident scenarios, provide a more detailed treatment of dose protraction effects, and include morbidity effects not considered in the Reactor Safety Study. 115 references, 20 figures, 19 tables

  19. Early history of scapular fractures.

    Bartoníček, Jan; Kozánek, Michal; Jupiter, Jesse B

    2016-01-01

    The first to use the term Scapula was Vesalius (1514-1564) and thus it has remained ever since. Probably the oldest injured scapula, from 250 million years ago, was described by Chinese authors of a skeletal examination of a fossilised remains of a dinosaur Yangchuanosaurus hepingensis. In humans, the oldest known scapular fractures date back to the prehistoric and early historic times. In ancient times, a fracture of acromion was described in the treatises of Hippocrates. Early modern history of the treatment of scapular fractures is closely interlinked with the history of the French surgery. The first to point out the existence of these fractures were Petit, Du Verney and Desault in the 18th century. The first study devoted solely to scapular fractures was published by Traugott Karl August Vogt in 1799. Thomas Callaway published in 1849 an extensive dissertation on injuries to the shoulder girdle, in which he discussed a number of cases known at that time. The first radiograph of a scapular fracture was published by Petty in 1907. Mayo Robson (1884), Lambotte (1913) and Lane (1914) were pioneers in the surgical treatment of these fractures, followed in 1923 by the French surgeons Lenormat, Dujarrier and Basset. The first internal fixation of the glenoid fossa, including a radiograph, was published by Fischer in 1939.

    2014-07-20

    Ectopic pregnancy is a high-risk condition that occurs in 2% of reported pregnancies. This percentage is fivefold higher than that registered in the 1970s. Since 1970 there has been a two-fold increase in the ratio of ectopic pregnancies to all reported pregnancies in Hungary and in 2012 7.4 ectopic pregnancies per thousand registered pregnancies were reported. Recently, the majority (80%) of cases can be diagnosed in early stage, and the related mortality objectively decreased in the past few decades to 3.8/10,000 ectopic pregnancies. If a woman with positive pregnancy test has abdominal pain and/or vaginal bleeding the physician should perform a work-up to safely exclude the possibility of ectopic pregnancy. The basis of diagnosis is ultrasonography, especially vaginal ultrasound examination and measurement of the β-subunit of human chorionic gonadotropin. The ultrasound diagnosis is based on the visualization of an ectopic mass rather than the inability to visualize an intrauterine pregnancy. In some questionable cases the diagnostic uterine curettage or laparoscopy may be useful. The actuality of this topic is justified by practical difficulties in obtaining correct diagnosis, especially in the early gestational time.

    The EGU encourages early career scientists (ECS) to become involved in interdisciplinary research in the Earth, planetary and space sciences, through sessions, social events and short courses at the annual General Assembly in April and throughout the year. Through division-level representatives, all ECS members can have direct input into matters of the division. A Union-wide representative, who sits on the EGU Council, ensures that ECS are heard at a higher level in the Union too. After a brief introduction as to how the network is organised and structured, this presentation will discuss how EGU ECS activities have been tailored to the needs of ECS members and how those needs have been identified. Reaching and communicating opportunities to ECS remains an ongoing challenge; they will be discussed in this presentation too, as well as some thoughts on how to make them more effective. Finally, the service offered to EGU ECS members would certainly benefit from building links and collaboration with other early career networks in the geosciences. This presentation will outline some of our efforts in that direction and the challenges that remain.

    1992-01-01

    To investigate predictable ultrasonographic findings of early abortion. To investigate objective rules for the screening of abortion. Ultrasonographic examination of 111 early pregnancies between the sixth and ninth week in women who had regular 28 day menstrual cycles was performed. Ultrasonographic measurements of the gestational sac, crown rump length and fetal heart rate were performed using a linear array real time transducer with doppler ultrasonogram. All measurements of 17 early abortions were compared to those of 94 normal pregnancies. Most of early aborted pregnancies were classified correctly by discriminant analysis with G-SAC and CRL (G-SAC=0.5 CRL + 15, sensitivity 76.5%, specificity 96.8%). With the addition of FHR, 94.1% of early abortions could be predicted. In conclusion, ultrasonographic findings of early intrauterine growth retardation, small gestational sac and bradycardia can be predictable signs suggestive of poor prognosis of early pregnancies

Concomitant presence of other venereal disease to account for the atypical manifestations was discounted- by appropriate laboratory tests, response to therapeutic agents and follow up.

  7. LEP vacuum chamber, early prototype

    CERN Multimedia

    CERN PhotoLab

    1978-01-01

    The structure of LEP, with long bending magnets and little access to the vacuum chamber between them, required distributed pumping. This is an early prototype for the LEP vacuum chamber, made from extruded aluminium. The main opening is for the beam. The small channel to the right is for cooling water, to carry away the heat deposited by the synchroton radiation from the beam. The 4 slots in the channel to the left house the strip-shaped ion-getter pumps (see 7810255). The ion-getter pumps depended on the magnetic field of the bending magnets, too low at injection energy for the pumps to function well. Also, a different design was required outside the bending magnets. This design was therefore abandoned, in favour of a thermal getter pump (see 8301153 and 8305170).

  8. Early Earthquakes of the Americas

    Ni, James

    2004-11-01

    Robert Kovach's second book looks at the interplay of earthquake and volcanic events, archeology, and history in the Americas. Throughout history, major earthquakes have caused the deaths of millions of people and have damaged countless cities. Earthquakes undoubtedly damaged prehistoric cities in the Americas, and evidence of these events could be preserved in archeological records. Kovach asks, Did indigenous native cultures-Indians of the Pacific Northwest, Aztecs, Mayas, and Incas-document their natural history? Some events have been explicitly documented, for example, in Mayan codices, but many may have been recorded as myth and legend. Kovach's discussions of how early cultures dealt with fearful events such as earthquakes and volcanic eruptions are colorful, informative, and entertaining, and include, for example, a depiction of how the Maya would talk to maize plants in their fields during earthquakes to reassure them.

  9. Galaxies in the Early Universe

    DEFF Research Database (Denmark)

    Krogager, Jens-Kristian

    Understanding how galaxies evolved from the early Universe through cosmic time is a fundamental part of modern astrophysics. In order to study this evolution it is important to sample the galaxies at various times in a consistent way through time. In regular luminosity selected samples, our...... analyses are biased towards the brightest galaxies at all times (as these are easier to observe and identify). A complementary method relies on the absorption imprint from neutral gas in galaxies, the so-called damped Ly absorbers (DLAs) seen towards distant bright objects. This thesis seeks to understand...... how the absorption selected galaxies relate to the emission selected galaxies by identifying the faint glow from the absorbing galaxies at redshift z 2. In Chapters 2 and 3, the emission properties of DLAs are studied in detail using state-of-the-art instrumentation. The specific DLA studied...

    The hot gas in early type galaxies (ETGs) plays a crucial role in understanding their formation and evolution. As the hot gas is often extended to the outskirts beyond the optical size, the large scale structural features identified by Chandra (including jets, cavities, cold fronts, filaments and tails) point to key evolutionary mechanisms, e.g., AGN feedback, merging history, accretion, stripping and star formation and its quenching. We have systematically analyzed the archival Chandra data of ~100 ETGs to study the hot ISM. We produce the uniformly derived data products with spatially resolved spectral information and will make them accessible via a public web site. With 2D spectral infomation, we further discuss gas morphology, scaling relations, X-ray based mass profiles and their implications related to various physical mechanisms (e.g., stellar and AGN feedback).

    Brandenberger, R.H.

    1987-01-01

    When studying the evolution of the very early universe it is necessary to use a description of matter which is appropriate at very high energies, namely in terms of quantum fields. In such models there may be a period during which the ratio of pressure and energy density is - 1, an equation of state which leads to an exponential expansion of the universe (inflation). There may also arise stable topological defects similar to vortex lines in condensed matter physics. These defects (cosmic strings) form seeds about which gas can accrete to form galaxies and clusters of galaxies. The author reviews inflation and cosmic strings, emphasizing their role in generating the energy density perturbations which are required in order to explain the existence of structures in the universe

  14. Acute leukemia in early childhood

    Directory of Open Access Journals (Sweden)

    M. Emerenciano

    2007-06-01

    Full Text Available Acute leukemia in early childhood is biologically and clinically distinct. The particular characteristics of this malignancy diagnosed during the first months of life have provided remarkable insights into the etiology of the disease. The pro-B, CD10 negative immunophenotype is typically found in infant acute leukemia, and the most common genetic alterations are the rearrangements of the MLL gene. In addition, the TEL/AML1 fusion gene is most frequently found in children older than 24 months. A molecular study on a Brazilian cohort (age range 0-23 months has detected TEL/AML1+ve (N = 9, E2A/PBX1+ve (N = 4, PML/RARA+ve (N = 4, and AML1/ETO+ve (N = 2 cases. Undoubtedly, the great majority of genetic events occurring in these patients arise prenatally. The environmental exposure to damaging agents that give rise to genetic changes prenatally may be accurately determined in infants since the window of exposure is limited and known. Several studies have shown maternal exposures that may give rise to leukemogenic changes. The Brazilian Collaborative Study Group of Infant Acute Leukemia has found that mothers exposed to dipyrone, pesticides and hormones had an increased chance to give birth to babies with infant acute leukemia [OR = 1.48 (95%CI = 1.05-2.07, OR = 2.27 (95%CI = 1.56-3.31 and OR = 9.08 (95%CI = 2.95-27.96], respectively. This review aims to summarize recent clues that have facilitated the elucidation of the biology of early childhood leukemias, with emphasis on infant acute leukemia in the Brazilian population.

    Homochirality is a property of living systems on Earth. The time, the place, and the way in which it appeared are uncertain. In a prebiotic scenario two situations are of interest: either an initial small bias for handedness of some biomolecules arouse and progressed with life, or an initial slight excess led to the actual complete dominance of the known chiral molecules. A definitive answer can probably never be given, neither from the fields of physics and chemistry nor biology. Some arguments can be advanced to understand if homochirality is necessary for the initiation of a prebiotic homochiral polymer chemistry, if this homochirality is suggesting a unique origin of life, or if a chiral template such as a mineral surface is always required to result in an enantiomeric excess. A general description of the early Earth scenario will be presented in this chapter, followed by a general description of some clays, and their role as substrates to allow the concentration and amplification of some of the building blocks of life.

  16. Early innovation - NRX and NRU

    Collins, J.H.

    1986-01-01

    Innovation has been an integral part of the entire histories of both the NRX and NRU reactors, their systems and the programs conducted in them. I have chosen to emphasize the period of the first decade of NRX operation because it was such a time of discovery. What might be considered obvious today was unknown then. It was at the end of this period that NRU's operation began. This is not a technical paper nor is it intended to be. Rather, it is my version of an oral history of the time recorded from my memory of events or from information told to me by others. The basic facts have been verified through reference to Dr. D.A. Keys' excellent reports and the other progress reports of the time. Some of my old colleagues might have chosen different examples. I do believe that what is included is a reasonable cross-section of examples of early innovation. To help orient those who are not familiar with NRX and NRU and perhaps jog the memories of others, appended are a cutaway view and simple cross-section of each reactor as well as a schematic view of the uranium fuel rod originally used in NRX. With the startup of NRX in 1947 Canada became a major player on the world's nuclear stage. Much work had been done before this date. There was early research by Canadian scientists such as Dr. G.C. Laurence at NRC. As part of the war effort, through the collaborative efforts with our allies led by the U.K. and the U.S. the program to build NRX evolved. At the time the primary purpose of the reactor was to produce Plutonium-239 and Uranium-233. ZEEP was the first reactor to operate outside the U.S. as a step in the development of NRX. The Canadian nuclear industry owes much to those who contributed to the design and building of NRX. They did an outstanding job. A reactor that was built with war in mind was so astonishingly flexible that it became one of the world's renowned contributors to the peaceful uses of nuclear energy

    Policy makers, advocates and experts agree that the current delivery of early childhood development programs is fragmented. Many point to the education system as a better alternative for a more coherent approach that has the necessary infrastructure in place in communities, and is well placed to meet the needs of all young children and their families. In other jurisdictions, early childhood development programs have moved into education. In Canada, provincial and local school authorities are taking on more early childhood programs.

    Eight cases of childhood cerebellar ataxia were reported. All these cases showed chronic cerebellar ataxia with early onset, and the other diseases of cerebellum such as infections, neoplasms and storage diseases were excluded by clinical symptoms and laboratory findings including blood counts, blood chemistry, lactate, pyruvate, ceruloplasmine, urinalysis, serum immunoglobulins, amino acid analysis in blood and urine, CSF analysis, leukocyte lysosomal enzymes, MCV, EMG, EEG and brain X-CT. Two pairs of siblings were included in this study. The clinical diagnosis were cerebellar type (5), spinocerebellar type (1), one Marinesco-Sjoegren syndrome and undetermined type (1). The age of onset was 1 to 5 years. The chief complaint was motor developmental delay in 6 cases; among them 5 patients could walk alone at the ages of 2 to 3 years'. Mental retardation was observed in 7 cases and epilepsy in 2. TRH was effective in 5 cases. The MRI study revealed that the area of medial sagittal slice of the cerebellum was reduced significantly in all cases and also that of pons was reduced in 5 cases. Different from typical adult onset spinocerebellar degenerations, most of the present cases have achieved slow developmental milestones and the clinical course was not progressive. Genetic factors are suspected in the pathogenesis of this disease in some cases. (author)

  2. Cosmology and the early universe

    In the beginning the universe was in a hot dense state nearly 13.8 billion years ago. The thermal history of the universe was traced back to an era when the temperature was about 1012K. At this early time, the universe was filled with particles-mostly photons and leptons- whose interactions are hopefully weak enough to allow this medium to be treated as a more or less ideal gas. However, if we look back a little further, into the first 0.0001 second of cosmic history when the temperature was above 1012K. At such temperatures, there will be present in thermal equilibrium copious numbers of strongly interacting particles-mostly masons and baryons-with a mean interparticle distance less than a Compton wavelength. These particles will be in a state of continual mutual interaction, and cannot reasonably be expected to obey any simple equation of state. The inflationary epoch lasted from 10-36seconds after the Big Bang to sometime between 10-33and 10-32seconds. Matter and energy created in this time. Right after that space expanded exponentially with enormous rate of 74.3 +/-2.1Km per second per Mpc.

  3. Casebooks in Early Modern England:

    Science.gov (United States)

    Kassell, Lauren

    2014-01-01

    summary Casebooks are the richest sources that we have for encounters between early modern medical practitioners and their patients. This article compares astrological and medical records across two centuries, focused on England, and charts developments in the ways in which practitioners kept records and reflected on their practices. Astrologers had a long history of working from particular moments, stellar configurations, and events to general rules. These practices required systematic notation. Physicians increasingly modeled themselves on Hippocrates, recording details of cases as the basis for reasoned expositions of the histories of disease. Medical records, as other scholars have demonstrated, shaped the production of medical knowledge. Instead, this article focuses on the nature of casebooks as artifacts of the medical encounter. It establishes that casebooks were serial records of practice, akin to diaries, testimonials, and registers; identifies extant English casebooks and the practices that led to their production and preservation; and concludes that the processes of writing, ordering, and preserving medical records are as important for understanding the medical encounter as the records themselves.

  4. Early vision and focal attention

    Julesz, Bela

    1991-07-01

    At the thirty-year anniversary of the introduction of the technique of computer-generated random-dot stereograms and random-dot cinematograms into psychology, the impact of the technique on brain research and on the study of artificial intelligence is reviewed. The main finding-that stereoscopic depth perception (stereopsis), motion perception, and preattentive texture discrimination are basically bottom-up processes, which occur without the help of the top-down processes of cognition and semantic memory-greatly simplifies the study of these processes of early vision and permits the linking of human perception with monkey neurophysiology. Particularly interesting are the unexpected findings that stereopsis (assumed to be local) is a global process, while texture discrimination (assumed to be a global process, governed by statistics) is local, based on some conspicuous local features (textons). It is shown that the top-down process of "shape (depth) from shading" does not affect stereopsis, and some of the models of machine vision are evaluated. The asymmetry effect of human texture discrimination is discussed, together with recent nonlinear spatial filter models and a novel extension of the texton theory that can cope with the asymmetry problem. This didactic review attempts to introduce the physicist to the field of psychobiology and its problems-including metascientific problems of brain research, problems of scientific creativity, the state of artificial intelligence research (including connectionist neural networks) aimed at modeling brain activity, and the fundamental role of focal attention in mental events.

    This paper explores the question of how Roma women’s situation influences Roma children’s survival, growth and development in the early years. It focuses specifically on the barriers and opportunities for action that Roma women experience and how these influence their possibilities to engage in e...... an assessment of the mothers’ capacity to internalize and act upon advice. It is argued that supporting Roma women’s access to human rights is likely to have positive outcomes for the women and their families, especially the young children...... in efforts for their young children. The paper adopts the perspective that in poor and socially excluded Roma communities, young children’s survival, growth and development cannot be addressed effectively if the rights of women are overlooked. Roma women navigate in contexts where they, as women, experience...... multiple barriers to their agency in particular due to multiple forms of discrimination and living in poverty on the margins of society. In such contexts of disempowerment, programme responses are likely to meet with limited success if they seek to teach mothers about child care and rearing, without...

  7. From early wireless to Everest.

    Science.gov (United States)

    Allen, A

    1998-01-01

    Medical information has been transmitted using wireless technologies for almost 80 years. A "wired wireless" electronic stethoscope was developed by the U.S. Army Signal Corps in the early 1920's, for potential use in ship-to-shore transmission of cardiac sounds. [Winters SR. Diagnosis by wireless. Scientific American June 11, 1921, p. 465] Today, wireless is used in a wide range of medical applications and at sites from transoceanic air flights to offshore oil platforms to Mt. Everest. 'Wireless LANs' are often used in medical environments. Typically, nurses and physicians in a hospital or clinic use hand-held "wireless thin client" pen computers that exchange patient information and images with the hospital server. Numerous companies, such as Fujitsu (article below) and Cruise Technologies (www.cruisetech.com) manufacture handheld pen-entry computers. One company, LXE, integrates radio-frequency (RF) enhanced hand-held computers specifically designed for production use within a wireless LAN (www.lxe.com). Other companies (Proxim, Symbol, and others) supply the wireless RF LAN infrastructure for the enterprise. Unfortunately, there have been problems with widespread deployment of wireless LANs. Perhaps the biggest impediment has been the lack of standards. Although an international standard (IEEE 802.11) was adopted in 1997, most wireless LAN products still are not compatible with the equipment of competing companies. A problem with the current standard for LAN adapters is that throughput is limited to 3 Mbps--compared to at least 10 Mbps, and often 100 Mbps, in a hard-wired Ethernet LAN. An II Mbps standard is due out in the next year or so, but it will be at least 2 years before standards-compliant products are available. This story profiles some of the ways that wireless is being used to overcome gaps in terrestrial and within-enterprise communication.

  8. The Early History of Life

    Nisbet, E. G.; Fowler, C. M. R.

    2003-12-01

    The youth of the Earth is strange to us. Many of the most fundamental constraints on life may have been different, especially the oxidation state of the surface. Should we suddenly land on its Hadean or early Archean surface by some sci-fi accident, we would not recognize our home. Above, the sky may have been green or some other unworldly color, and above that the weak young Sun might have been unrecognizable to someone trying to identify it from its spectrum. Below, seismology would show a hot, comparatively low-viscosity interior, possibly with a magma ocean in the deeper part of the upper mantle (Drake and Righter, 2002; Nisbet and Walker, 1982), and a core that, though present, was perhaps rather smaller than today. The continents may have been small islands in an icy sea, mostly frozen with some leads of open water, ( Sleep et al., 2001). Into these icy oceans, huge protruding Hawaii-like volcanoes would have poured out vast far-spreading floods of komatiite lavas in immense eruptions that may have created sudden local hypercane storms to disrupt the nearby icebergs. And meteorites would rain down.Or perhaps it was not so strange, nor so violent. The child is father to the man; young Earth was mother to Old Earth. Earth had hydrogen, silicate rock below and on the surface abundant carbon, which her ancient self retains today. Moreover, Earth was oxygen-rich, as today. Today, a tiny part of the oxygen is free, as air; then the oxygen would have been in the mantle while the surface oxygen was used to handcuff the hydrogen as dihydrogen monoxide. Oxygen dihydride is dense, unlikely to fly off to space, and at the poles, rock-forming. Of all the geochemical features that make Earth unique, the initial degassing (Genesis 2 : b) and then the sustained presence of liquid water is the defining oddity of this planet. Early Earth probably also kept much of its carbon, nitrogen, and sulfur as oxide or hydride. And, after the most cataclysmic events had passed, ˜4.5 Ga

    The incidence of colorectal cancer has been gradually increasing in Japan, and if the present rate of increase is maintained it has been estimated that it will become the most common of all malignant neoplasms by the year 2000. It has been proved that colorectal cancer can be completely cured, if it is treated in its early phase. Early cancer of the large bowel is defined as a cancer which is limited to the mucosal membrane or submucosal layer, regardless of lymph node and distant metastases. Detection of early cancer improves the overall curability of colorectal cancer. The greatest number of early cancers of the large bowel are polypoid lesions in their macroscopic form, and depressed lesions are rarely encountered. Accordingly, the first step in the detection of early cancer starts with the screening of polypoid lesion by radiology and endoscopy. This paper is concerned with diagnostic accuracy of radiology in the screening of colorectal cancer with endoscopic correlation

  20. Long-term Consequences of Early Parenthood

    DEFF Research Database (Denmark)

    Johansen, Eva Rye; Nielsen, Helena Skyt; Verner, Mette

    Having children at an early age is known to be associated with unfavorable economic outcomes, such as lower education, employment and earnings. In this paper, we study the long-term consequences of early parenthood for mothers and fathers. Our study is based on rich register-based data that......, importantly, merges all childbirths to the children’s mothers and fathers, allowing us to study the consequences of early parenthood for both parents. We perform a sibling fixed effects analysis in order to account for unobserved family attributes that are possibly correlated with early parenthood...... (and to lesser extent employment), as fathers appear to support the family, especially when early parenthood is combined with cohabitation with the mother and the child. Heterogeneous effects reveal that individuals with a more favorable socioeconomic background are affected more severely than...

    Understanding the way in which animals diversified and radiated during their early evolutionary history remains one of the most captivating of scientific challenges. Integral to this is the 'Cambrian explosion', which records the rapid emergence of most animal phyla, and for which the triggering and accelerating factors, whether environmental or biological, are still unclear. Here we describe exceptionally well-preserved complex digestive organs in early arthropods from the early Cambrian of China and Greenland with functional similarities to certain modern crustaceans and trace these structures through the early evolutionary lineage of fossil arthropods. These digestive structures are assumed to have allowed for more efficient digestion and metabolism, promoting carnivory and macrophagy in early arthropods via predation or scavenging. This key innovation may have been of critical importance in the radiation and ecological success of Arthropoda, which has been the most diverse and abundant invertebrate phylum since the Cambrian.

  4. Evolution of Early Cenozoic marine temperatures

    1994-04-01

    The equator to high southern latitude sea surface and vertical temperature gradients are reconstructed from oxygen isotope values of planktonic and benthic foraminifers for the following five time intervals: late Paleocene, early Eocene, early middle Eocene, late Eocene, and early Oligocene. Paleotemperatures are calculated using standard oxygen isotope/temperature equations with adjustments to account for (1) variations in sea water δ18O related to changes in global ice volume over time and (2) latitudinal gradients in surface water δ18O. These reconstructions indicate that sea-surface temperatures (SST) of the Southern Oceans in the early Eocene were as high as 15°C, whereas temperatures during the late Paleocene and early middle Eocene reached maximum levels of 10°-12°C. By the late Eocene and early Oligocene high latitude SST had declined to 6 and 4°C, respectively. For most of the early Paleogene, low latitude sub-tropical temperatures remained constant and well within the range of Holocene temperatures (24°ndash;25°C) but by the late Eocene and early Oligocene declined to values in the range of 18° to 22°C. The late Paleogene apparent decline in tropical temperatures, however, might be artificial because of dissolution of near-surface foraminifera tests which biased sediment assemblages toward deeper-dwelling foraminifera. Moreover, according to recent plate reconstructions, it appears that the majority of sites upon which the late Eocene and early Oligocene tropical temperatures were previously established were located either in or near regions likely to have been influenced by upwelling. Global deepwater temperature on average paralleled southern ocean SST for most of the Paleogene. We speculate based on the overall timing and character of marine sea surface temperature variation during the Paleogene that some combination of both higher levels of greenhouse gases and increased heat transport was responsible for the exceptional high-latitude warmth

  5. Early markers of adult obesity: a review

    Science.gov (United States)

    Brisbois, T D; Farmer, A P; McCargar, L J

    2012-01-01

    Summary The purpose of this review was to evaluate factors in early childhood (≤5 years of age) that are the most significant predictors of the development of obesity in adulthood. Factors of interest included exposures/insults in the prenatal period, infancy and early childhood, as well as other socio-demographic variables such as socioeconomic status (SES) or birth place that could impact all three time periods. An extensive electronic and systematic search initially resulted in 8,880 citations, after duplicates were removed. Specific inclusion and exclusion criteria were set, and following two screening processes, 135 studies were retained for detailed abstraction and analysis. A total of 42 variables were associated with obesity in adulthood; however, of these, only seven variables may be considered as potential early markers of obesity based on the reported associations. Possible early markers of obesity included maternal smoking and maternal weight gain during pregnancy. Probable early markers of obesity included maternal body mass index, childhood growth patterns (early rapid growth and early adiposity rebound), childhood obesity and father's employment (a proxy measure for SES in many studies). Health promotion programmes/agencies should consider these factors as reasonable targets to reduce the risk of adult obesity. PMID:22171945

    Full Text Available Background: Oral fluids and food are traditionally introduced slowly after total abdominal hysterectomy (TAH. This descriptive study examined the effect and tolerance of early oral intake following this surgery. Methods: A retrospective chart review was conducted on 164 patients who had been on a clinical pathway following TAH. Comparisons in initiation of fluids and foods, and gastrointestinal effects were made between the early fed group (n=82 and the traditionally fed group (n=82. Results: Both groups had the similar gastrointestinal symptoms postoperatively, but the early fed group had an earlier bowel movement. The early fed group had a statistically significant shorter length of stay. Similar usage of anti-nausea medication and pain medication usage was noted between the two groups, except for a lower usage of Tylenol #3 (acetaminophen with codeine in the early fed group. Conclusions: This study found that early feeding could be tolerated well in TAH patients, with statistically significant improvements in usage of some pain medication and length of stay were noted in the early fed group.

    According to the existence of subclinical organ involvement pre-scleroderma should be divided into two subsets: very early and early disease. Pre-scleroderma patients included in the Spanish Scleroderma Registry (RESCLE) Cohort were reclassified into subsets. Differences were evaluated and the risk of progression to definite systemic sclerosis was estimated. The characteristics of very early and early SSc patients were compared. A logistic regression model was used to determine the risk factors of progression. 1632 patients were included, 36 (2.2%) in the very early subset and 111 (6.8%) in the early subset. There were no differences in sex, age at disease onset, duration of Raynaud's phenomenon, antinuclear antibodies or capillaroscopic findings. Three (8.3%) very early SSc patients evolved to definite SSc, 2 (5.6%) of them meeting the ACR/EULAR 2013 criteria, unlike 31 (28%) early SSc patients, 20 (24%) of them meeting the criteria (p=0.034). Digestive involvement was an independent risk factor of progression (OR 17; 95% CI, 6.1-47.2). The classification of early forms of scleroderma identifies patients with different prognostic risk of progression. The evolution to definite SSc is more frequent in early than in very early SSc patients. Digestive involvement is a risk factor of progression. An active assessment of organ damage in preclinical stages allows a correct classification and risk stratification, with implications for monitoring and treatment. Copyright © 2017 Elsevier B.V.

    Dementia is about 15% aged 65 and over people now, and is regarded as the common disease. Early symptoms, such as forgetfulness, tend to be overlooked. Alzheimer type dementia is now possible to treat with medication. Therefore, early diagnosis and early treatment are required. Prevention of dementia is also expected and dementia checkup attracts attention. Although there was little data with high evidence, I introduced some reports about dementia prevention including our data. Dementia prevention is an important issue and establishment of evidence is desired in the near future.

    2013-02-01

    To test Music Marker Theory (MMT) positing that early adolescents' preferences for nonmainstream types of popular music indicate concurrent and later minor delinquency. MMT was tested in a 4-year longitudinal study (n = 309). The results showed that early fans of different types of rock (eg, rock, heavy metal, gothic, punk), African American music (rhythm and blues, hip-hop), and electronic dance music (trance, techno/hardhouse) showed elevated minor delinquency concurrently and longitudinally. Preferring conventional pop (chart pop) or highbrow music (classic music, jazz), in contrast, was not related to or was negatively related to minor delinquency. Early music preferences emerged as more powerful indicators of later delinquency rather than early delinquency, indicating that music choice is a strong marker of later problem behavior. The mechanisms through which music preferences are linked to minor delinquency are discussed within the framework of MMT.

    Colorectal cancer is one of the leading causes of cancer associated morbidity and mortality. Main risk factors include advanced age, affected family members, male sex and lifestyle factors. The development of early adenoma to invasive cancer requires 10 and more years. Therefore, prevention via colonoscopy with polypectomy and early detection of asymptomatic stages is possible. Colonoscopy is a diagnostic and therapeutic tool with the highest sensitivity for precancerous lesions and early cancers of the colon. New fecal immunological tests reveal a higher sensitivity for advanced adenoma and cancer than guaiac based hemoccult tests while maintaining a high specificity. Molecular stool and blood tests are promising new developments. However, similar to virtual colonoscopy and colon capsule endoscopy, they have so far not been established as routine instruments for prevention and early detection of colorectal cancer. © Georg Thieme Verlag KG Stuttgart · New York.

    2016-01-01

    Background: Early sport specialization is not a requirement for success at the highest levels of competition and is believed to be unhealthy physically and mentally for young athletes. It also discourages unstructured free play, which has many benefits. Purpose: To review the available evidence on early sports specialization and identify areas where scientific data are lacking. Study Design: Think tank, roundtable discussion. Results: The primary outcome of this think tank was that there is no evidence that young children will benefit from early sport specialization in the majority of sports. They are subject to overuse injury and burnout from concentrated activity. Early multisport participation will not deter young athletes from long-term competitive athletic success. Conclusion: Youth advocates, parents, clinicians, and coaches need to work together with the sport governing bodies to ensure healthy environments for play and competition that do not create long-term health issues yet support athletic competition at the highest level desired.

    2011-01-01

    Early infarct detection on brain images is difficult due to their subtle signs. However, early detection on infarct sign can provide early treatment to preserve other healthy brain tissues. In this project, a technique is proposed to enhance the interpretation of computer tomography (CT) brain images to improve the detection of brain infarct. The proposed method stretches the contrast of the CT brain image based on Hounsfield units and applies colourisation to the contrast-stretched image to improve the observation of the CT brain image by eye sight. A test was conducted in a private university in order to evaluate the proposed method. The results show that the detection of early infarct, carried by the students was improved by 5% with the help of the proposed method. (author)

    Full Text Available Objective: to substantiate a need for early use of extracorporeal homeostatic correction techniques during cardiosurgical intensive care. Subjects and methods: A non-randomized study was conducted in 63 cardiosurgical patients with postoperatively evolving multiple organ dysfunction. The clinical efficiency and economic expediency of the early initiation of homeostatic correction were estimated by continuous low-flow venovenous hemofiltration on a Prisma apparatus. Results. The study has demonstrated the advantages of early (within the 36-hour postoperative period initiation of a procedure by the time of organ dysfunction recovery, the length of stay on a resuscitation bed, and pharmacoeconomic indices. Conclusion. The early (at the stage of dysfunction, until hemostasis becomes stable and in the absence of drainage volume losses initiation of hemofiltration in the development of multiple organ dysfunction after surgical interventions has been clinically and economically warranted.

    Full Text Available Prostate cancer (PCa has become to have the highest incidence and the second mortality rate in western countries, affecting men's health to a large extent. Although prostate-specific antigen (PSA was discovered to help diagnose the cancer in an early stage for decades, its specificity is relative low, resulting in unnecessary biopsy for healthy people and over-treatment for patients. Thus, it is imperative to identify more and more effective biomarkers for early diagnosis of PCa in order to distinguish patients from healthy populations, which helps guide an early treatment to lower disease-related mortality by noninvasive or minimal invasive approaches. This review generally describes the current early diagnostic biomarkers of PCa in addition to PSA and summarizes the advantages and disadvantages of these biomarkers.

    2010-09-09

    The last decade has produced an explosion in neuroscience research examining young children's early processing of language. Noninvasive, safe functional brain measurements have now been proven feasible for use with children starting at birth. The phonetic level of language is especially accessible to experimental studies that document the innate state and the effect of learning on the brain. The neural signatures of learning at the phonetic level can be documented at a remarkably early point in development. Continuity in linguistic development from infants' earliest brain responses to phonetic stimuli is reflected in their language and prereading abilities in the second, third, and fifth year of life, a finding with theoretical and clinical impact. There is evidence that early mastery of the phonetic units of language requires learning in a social context. Neuroscience on early language learning is beginning to reveal the multiple brain systems that underlie the human language faculty. 2010 Elsevier Inc. All rights reserved.

  9. The need to better classify and diagnose early and very early rheumatoid arthritis.

    Science.gov (United States)

    Zeidler, Henning

    2012-02-01

    Early rheumatoid arthritis (RA) and very early RA are major targets of research and clinical practice. Remission has become a realistic goal in the management of RA, particularly in early disease. The 2010 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) RA classification criteria, the EULAR treatment recommendations for RA, and the EULAR recommendations for the management of early arthritis focus on early disease and translate the knowledge related to early RA into classification and management. Nevertheless, there is a need for further improvement and progress. Results from 6 recent studies are summarized, evaluating the performance of the 2010 ACR/EULAR RA classification criteria. The data show a significant risk of misclassification, and highlight that overdiagnosis and underdiagnosis may become important issues if the criteria recommend synthetic and biological disease-modifying antirheumatic drugs. Therefore, some considerations are presented on how the current problems and limitations could be overcome in clinical practice and future research. A consensus is needed to better define the early phase of RA and differentiate from other early arthritis. The possible effect of misclassification on spontaneous and drug-induced remission of early and very early RA awaits further elucidation. Such research will eventually lead to more reliable diagnostic and classification criteria for new-onset RA.

    We discuss the role played by right-handed sterile neutrinos in the early universe. We show how well known {sup 4}He constraint on the number of relativistic degrees of freedom at early times limits the equilibration of the right handed neutrino sea with the background plasma. We discuss how this allows interesting constraints to be placed on neutrino properties. In particular, a new limit on the Dirac mass of the neutrino is presented. 12 refs.

    Full Text Available This paper is about early roots of supersymmetry, as found in the literature from 1940s and early 1950s. There were models where the power of “partners” in alleviating divergences in quantum field theory was recognized. However, other currently known remarkable features of supersymmetry, such as its role in the extension of the Poincaré group, were not known. There were, of course, no supersymmetric nonabelian quantum field theories in those days.

    The early development of the trochophore larva of the aplacophoran Chaetoderma nitidulum (Mollusca: Caudofoveata = Chaetodermomorpha) is described using scanning and transmission electron microscopy and using fluorescence staining and confocal laser scanning microscopy of the muscle system. The m...... of the early anlagen of the circular body wall muscles does not show the anterior-posterior mode of formation that is typical for annelids, thus strengthening the hypothesis of a non-segmented ancestry of Mollusca....

  20. Music as therapy in early history.

    Science.gov (United States)

    Thaut, Michael H

    2015-01-01

    The notion of music as therapy is based on ancient cross-cultural beliefs that music can have a "healing" effect on mind and body. Explanations for the therapeutic mechanisms in music have almost always included cultural and social science-based causalities about the uses and functions of music in society. However, it is also important to note that the view of music as "therapy" was also always strongly influenced by the view and understanding of the concepts and causes of disease. Magical/mystical concepts of illness and "rational" medicine probably lived side by side for thousands of years. Not until the late-nineteenth and early-twentieth centuries were the scientific foundations of medicine established, which allowed the foundations of music in therapy to progress from no science to soft science and most recently to actual brain science. Evidence for "early music therapy" will be discussed in four broad historical-cultural divisions: preliterate cultures; early civilizations in Mesopotamia, Egypt, Israel; Greek Antiquity; Middle Ages, Renaissance, and Baroque. In reviewing "early music therapy" practice, from mostly unknown periods of early history (using preliterate cultures as a window) to increasingly better documented times, including preserved notation samples of actual "healing" music, five theories and applications of early music therapy can be differentiated. © 2015 Elsevier B.V.

    The CT findings of the acute cerebral infarction are well known. However the CT findings of early stroke within 24 hours of the onset have not been sufficiently reported. The purpose of this study is to evaluate early acute cerebral infarction on CT within 24 hours after ictus. The early and accurate CT diagnosis could lead to the appropriate therapy and improved outcome of the patients. Authors retrospectively analyzed 16 patients with early acute cerebral infarction. Acute cerebral infarction was confirmed by follow-up CT in 11 patients, SPECT in 4 patients, and MRI in 1 patient. The CT findings of early acute cerebral infarction include effacement of cortical sulci or cistern (n = 16, 100%), hyperattenuation of MCA (n = 3), obscuration of lentiform nucleus (n = 6), loss of insular ribbon (n = 6) and subtle low density in hemisphere (n = 5). The most frequent finding was effacement of cortical sulci in our study, and it was thought to be the most important sign of early acute cerebral infarction.

    The cellular mechanisms of tendinopathy remain unclear particularly with respect to the role of inflammation in early disease. The authors previously identified increased levels of inflammatory cytokines in an early human model of tendinopathy and sought to extend these studies to the cellular analysis of tissue. To characterize inflammatory cell subtypes in early human tendinopathy, the authors explored the phenotype and quantification of inflammatory cells in torn and control tendon samples. Controlled laboratory study. Torn supraspinatus tendon and matched intact subscapularis tendon samples were collected from 20 patients undergoing arthroscopic shoulder surgery. Control samples of subscapularis tendon were collected from 10 patients undergoing arthroscopic stabilization surgery. Tendon biopsy samples were evaluated immunohistochemically by quantifying the presence of macrophages (CD68 and CD206), T cells (CD3), mast cells (mast cell tryptase), and vascular endothelium (CD34). Subscapularis tendon samples obtained from patients with a torn supraspinatus tendon exhibited significantly greater macrophage, mast cell, and T-cell expression compared with either torn supraspinatus samples or control subscapularis-derived tissue (P shoulders with supraspinatus ruptures. This study provides evidence for an inflammatory cell infiltrate in early mild/moderate human tendinopathy. In particular, the authors demonstrate significant infiltration of mast cells and macrophages, suggesting a role for innate immune pathways in the events that mediate early tendinopathy. Clinical Relevance Further mechanistic studies to evaluate the net contribution and hence therapeutic utility of these cellular lineages and their downstream processes may reveal novel therapeutic approaches to the management of early tendinopathy.

    The rapid increase of breast cancer in Taiwan has prompted the authors to evaluate the predictive factors of early menarche among contemporary Taiwanese girls. A total of 895 four-grade girls from eight elementary schools in Taipei City and County were identified as a closed cohort from the first semester of 1993. Data were collected from self-administered questionnaires and school records. A total of 799 girls who had not menstruated in the first year remained in the group through 1994. The effects of potential predictive factors were assessed by logistic regression. Among the 799 girls followed, 69 (8.6%) had first menstruation between the fourth and fifth grades. Height, weight, body mass index and maternal early onset of menarche were positively related to the onset of menarche within the preceding year. Energy consumption during exercise showed only moderate association after being adjusted for age and weight. Calorie intake from junk food was not associated with early menarche within the preceding year. Poor interpersonal family relationships and stressful life events also showed a moderate association with early menarche. The data obtained supported the hypothesis that height, weight, body mass index and maternal early menarche are positive predictive factors of early menarche. The effects of exercise and childhood stress are less prominent.

    With the help of radiation induced early and late flowering mutantlines of jute, studies have been made to determine the biochemical factors which could regulate the induction and expression of genes for the flowering processes in this plant. Comparative biochemical investigations were done with the parameters like : plant pigments (Chlorophyl a, b and carotenoides), auxin/antiauxin, and gibberellin/anti-gibberellin type of substances. Quantitative as well as qualitative differences of plant pigments were observed between the early and late flowering lines. Extracts of early flowering lines have been found to induce earliness in the late flowering mother variety of jute (D-154). Re-isolated growth inhibitors of early flowering lines have also been found to induce earliness in the late flowering mother variety (D-154). (author)

    This study examined developmentally salient risk and protective factors of adolescent substance use assessed during early childhood and early adolescence using a sample of 310 low-income boys. Child problem behavior and proximal family risk and protective factors (i.e., parenting and maternal depression) during early childhood, as well as child and family factors and peer deviant behavior during adolescence, were explored as potential precursors to later substance use during adolescence using structural equation modeling. Results revealed that early childhood risk and protective factors (i.e., child externalizing problems, mothers' depressive symptomatology, and nurturant parenting) were indirectly related to substance use at the age of 17 via risk and protective factors during early and middle adolescence (i.e., parental knowledge and externalizing problems). The implications of these findings for early prevention and intervention are discussed.

    Full Text Available Each child with Autism Spectrum Disorder has different symptoms, skills and types of impairment or disorder with other children. This is why the word “spectrum” is included in this disorder. Eapen, Crncec, and Walter, 2013 claimed that there was an emerging evidence that early interventions gives the greatest capacity of child’s development during their first years of life as “brain plasticity” are high during this period. With this, the only intervention program model for children as young as 18 months that has been validated in a randomized clinical trial is “Early Start Denver Model” (ESDM. This study aimed to determine the effectiveness of the outcome of “Early Start Denver Model” (ESDM towards young children with Autism Spectrum Disorders. This study made use of meta-analysis method. In this study, the researcher utilized studies related to “Early Start Denver Model (ESDM” which is published in a refereed journal which are all available online. There were five studies included which totals 149 children exposed to ESDM. To examine the “pooled effects” of ESDM in a variety of outcomes, a meta-analytic procedure was performed after the extraction of data of the concrete outcomes. Comprehensive Meta Analysis Version 3.3.070 was used to analyze the data.  The effectiveness of the outcome of “Early Start Denver Model” towards young children with Autism Spectrum Disorders (ASD highly depends on the intensity of intervention and the younger child age. This study would provide the basis in effectively implementing an early intervention to children with autism such as the “Early Start Denver Model” (ESDM that would show great outcome effects to those children that has “Autism Spectrum Disorder”.

    Bipolar disorder is a chronic psychiatric disease with a high prevalence and is a major psychosocial and medical burden. The exact etiological pathways of bipolar disorder are not fully understood. Genetic factors are known to play an important role in the etiology of bipolar disorder. However, high rates of discordance among identical twins and a growing body of evidence that environmental factors such as early stress can influence the onset and course of psychiatric diseases underline the importance of additional etiological mechanisms of bipolar disorders. There has been little investigation about early trauma in bipolar disorder. The aim of this study was to review the literature on the association between early traumatic interactions like child neglect, mistreatment, abuse or early parental separation and the occurrence of bipolar disorder in adulthood or impact on the course of the disease. Studies investigating associations between child neglect, mistreatment, abuse or early parental separation and occurrence of bipolar disorder in adulthood or impact on the course of the disease were searched in the Pubmed database. More than 700 articles were sorted independently by two of the authors using predefined criteria. Only research articles, reviews and meta-analyses were selected for this review. 53 articles met the inclusion criteria. To date, four systematic reviews partially addressed our research question. Early trauma is more frequently found in the past of bipolar patients than in the general population. Studies support a harmful effect of childhood trauma on the course of bipolar disease, with more anxious, depressive or psychotic symptoms, an early age of onset and a worse prognosis. Early trauma is more often found in the past of bipolar adult patients than the general population and studies support a harmful effect of childhood trauma on the course of bipolar disease, with more anxious, depressive or psychotic symptoms, an early age of onset and a

    Full Text Available This study aims to make learning media for Early Childhood Education in the form especially its mobile applications for Android-based smartphones. In the process of teaching and learning for Early Childhood Education is still often found constraints experienced teaching force is limited props so that learners are less eager to learn. In addition, parents also have difficulty returning to guide or teach the learning materials at home because it has no alternative instructional media. In compiling this research report author uses the Android-based Mobile Devices Applications created using the Java programming language through the Eclipse editor. Based on the results of the research, concluded that these applications can be applied in the latest version of the Android platform to its current platform version of Jellybean. Application of Learning can be used as an alternative way of learning for Early Childhood Education so as to overcome the lack of props in institutions of Early Childhood Education, can be used to be taught at home, and provide new teaching methods to early childhood so that a form of learning that is obtained is not the monotony of one form of learning how.

    Full Text Available Michael Untch1, Christian Jackisch21Interdisciplinary Breast Centre, Helios Klinikum Berlin-Buch, University Charité, Berlin, Germany; 2Department of Gynecology/Obstetrics, Klinikum Offenbach GmbH, Offenbach, GermanyAbstract: The adjuvant treatment of women with endocrine-sensitive early breast cancer has been dominated for the last 40 years by tamoxifen. However, the side-effects associated with this therapy have prompted a search for safer and biochemically more selective endocrine agents and led to the development of the third-generation aromatase inhibitors (AIs anastrozole, letrozole and exemestane. Promising results in advanced disease have paved the way for treating early breast cancer, and AIs are increasingly replacing tamoxifen in the adjuvant setting. Several large, randomized trials with AIs have been completed or are ongoing in women with early-stage breast cancer, documenting the significant impact that these drugs are making on the risk for recurrence of breast cancer. As a result, there is increasing and widespread use of AI therapy for the treatment of early-stage endocrine-responsive breast cancer. This review summarizes the data for exemestane in the adjuvant setting, showing that a switch to exemestane after 2 to 3 years of tamoxifen therapy is associated with a statistically significant survival benefit and is regarded as being sensitive by international and national experts.Keywords: early breast cancer, adjuvant setting, endocrine-sensitive, tamoxifen, aromatase inhibitor, exemestane, switch, IES 31, NSABP B-33, TEAM

    A 10-mG, 50 to 60-Hz magnetic field is in the intensity and frequency range that people worldwide are often exposed to in homes and in the workplace. Studies about the effects of 50- to 100-Hz electromagnetic fields on various species of animal embryos (fish, chick, fly, sea urchin, rat, and mouse) indicate that early stages of embryonic development are responsive to fluctuating magnetic fields. Chick, sea urchin, and mouse embryos are responsive to magnetic field intensities of 10-100 mG. Results from studies on sea urchin embryos indicate that exposure to conditions of rotating 60-Hz magnetic fields, e.g., similar to those in our environment, interferes with cell proliferation at the morula stage in a manner dependent on field intensity. The cleavage stages, prior to the 64-cell stage, were not delayed by this rotating 60-Hz magnetic field suggesting that the ionic surges, DNA replication, and translational events essential for early cleavage stages were not significantly altered. Studies of histone synthesis in early sea urchin embryos indicated that the rotating 60-Hz magnetic field decreased zygotic expression of early histone genes at the morula stage and suggests that this decrease in early histone production was limiting to cell proliferation. Whether these comparative observations from animal development studies will be paralleled by results from studies of human embryogenesis, as suggested by some epidemiology studies, has yet to be established. 38 refs.

  12. Environmental and genetic influences on early attachment

    Gervai Judit

    2009-09-01

    Full Text Available Abstract Attachment theory predicts and subsequent empirical research has amply demonstrated that individual variations in patterns of early attachment behaviour are primarily influenced by differences in sensitive responsiveness of caregivers. However, meta-analyses have shown that parenting behaviour accounts for about one third of the variance in attachment security or disorganisation. The exclusively environmental explanation has been challenged by results demonstrating some, albeit inconclusive, evidence of the effect of infant temperament. In this paper, after reviewing briefly the well-demonstrated familial and wider environmental influences, the evidence is reviewed for genetic and gene-environment interaction effects on developing early attachment relationships. Studies investigating the interaction of genes of monoamine neurotransmission with parenting environment in the course of early relationship development suggest that children's differential susceptibility to the rearing environment depends partly on genetic differences. In addition to the overview of environmental and genetic contributions to infant attachment, and especially to disorganised attachment relevant to mental health issues, the few existing studies of gene-attachment interaction effects on development of childhood behavioural problems are also reviewed. A short account of the most important methodological problems to be overcome in molecular genetic studies of psychological and psychiatric phenotypes is also given. Finally, animal research focusing on brain-structural aspects related to early care and the new, conceptually important direction of studying environmental programming of early development through epigenetic modification of gene functioning is examined in brief.

    Full Text Available Abstract Although bronchogenic carcinomas progress through a very well defined sequence of metaplasia, dysplasia and carcinoma in situ, very little is known about the early progression of glandular neoplasms of the lung. In particular, the early precursor lesion from which fully malignant adenocarcinomas arise has effectively eluded recognition, at least until recently. Several lines of evidence now implicate atypical adenomatous hyperplasia (AAH as an initial morphologic stage in multistep lung tumorigenesis. Despite its small size, AAH can be appreciated at the light microscopic level and characterized at the molecular genetic level. Indeed, the genetic characterization of AAH promises to further our understanding of lung cancer development and might facilitate the design of novel strategies for early detection of lung cancer.

  15. Rogue wave early warning through spectral measurements?

    International Nuclear Information System (INIS)

    We study the spectra of the Peregrine soliton and higher-order rational solutions of the nonlinear Schroedinger equation (NLSE), which we use as a model of the rogue waves in optics and in the deep ocean. We show that these solutions have specific triangular spectra that are certainly easily measurable in optical systems and which may be amenable to characterisation in ocean environments. As the triangular feature of the solutions appears at an early stage of their evolution, this raises the possibility of early detection and possible localized warning of the appearance of rogue waves. We anticipate that studying the characteristics of 'early warning spectra' of rogue waves may become an important future field of research.

    International Nuclear Information System (INIS)

    An emergency early warning system for the fourteen nuclear generating units in the country has been developed at the Nuclear Research Institute of the Ukrainian Academy of Sciences. All units are connected to the host computer in the emergency center of the State Nuclear Power Authority in Kiew and interconnected with each other. The early warning system is to make another reactor accident of the magnitude of Chernobyl impossible. Installation of the hardware is to begin at the South Ukraine 3 nuclear generating unit in 1997; the costs of the pilot project are estimated at U.S. Dollar 40 million. After subsequent feasibility studies, the software and the hardware may be modified; the early warning system could be in operation countrywide by 1999. (orig.) [de

In practice, the vigilant policing of bakers, butchers and brewers proved difficult. The positive economic effect of food policing was doubted early on and was reduced...... as a means to avoid food riots at the end the 18th century. In a major provincial market town like Aalborg, the food trade was policed in a similar manner by the town council and the police, but especially the intermediate trade proved difficult to stop.

    Malignant phyllodes tumor of the breast is an extremely rare entity usually presenting with similar clinical features with those of benign fibroadenoma. Due to its scarcity and clinical presentation, it is quite difficult for clinicians to suspect and diagnose the disease at its early stage. There is currently no consensus regarding adjunctive radiotherapy, hormonal therapy and systemic chemotherapy recommended for malignant phyllodes tumors. This report presents a case of early-stage malignant phyllodes tumor treated by lumpectomy only without adjunctive chemoradiation therapy, but with an excellent outcome. Early diagnosis and staging with high suspicion are crucial in malignant phyllodes tumor patients since they do not only improve the overall outcome of the disease after lumpectomy only but they also decrease morbidity and mortality with adjunctive chemoradiation therapy. This case report has been reported in line with the SCARE criteria (Agha et al., 2016 [1]). Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    2000-01-01

    Agonists of nicotinic cholinoreceptors (n-AChR) and 1-acetyl-4-methylpiperazine (100 microM) had no effect on early embryogenesis in sea urchins, while in the presence of phorbol-12-myristate-13-acetate (PMA) and various other protein kinase C activators, these agents induced rapid lysis of oocytes or early embryos, as a result of calcium shock. Many n-AChR ligands which do not penetrate into the cytoplasm (not being antagonists of muscarinic cholinoreceptors) protected against this cytotoxic effect. In the presence of PMA, acetylcholine and carbachol had actions which were much weaker than those of nicotine, while muscarine was completely inactive in these conditions. Thus, the surfaces of sea urchin oocytes and early embryos bear receptor structures, presumably n-AChR, which are functionally linked with second messengers which are endogenous protein kinase C activators.

    The barium enema has been a neglected tool in the diagnosis of early colon cancer. With appropriate attention to technical detail, the double contrast enema is capable of detecting the smallest malignant and pre-malignant lesions. Many of these early colon cancers are found in asymptomatic patients and these lesions are curable. The goal of a screening program should be to identify by history or by fecal occult blood testing patients at high risk for the development of colon cancer. These patients should be examined by high-quality double contrast enema in the search for these potentially lethal but curable lesions. In addition, we believe that any patient undergoing radiologic examination of the colon for whatever reason, should receive an examination of adequate quality to rule out an early colon cancer.
