    Twelve adults with maxillary width discrepancy of greater than 5 mm were treated by surgically assisted rapid maxillary expansion. The procedure consisted of bilateral zygomatic buttress and midpalatal osteotomies combined with the use of a tooth-borne orthopedic device postoperatively. Mean palatal expansion of 7.5 mm (range of 6 to 13 mm), measured in the first molar region, was achieved within 3 weeks in all patients. Expansion remained stable during the 12-month study period, with a mean relapse for the entire group of 0.88 +/- 0.48 mm. Morbidity was limited to mild postoperative discomfort. The results of this preliminary study indicated that surgically assisted rapid maxillary expansion is a safe, simple, and reliable procedure for achieving a permanent increase in skeletal maxillary width in adults. Further study is necessary to document the three-dimensional movements of the maxillary segments and long-term stability of the skeletal and dental changes.

    A major challenge in the era of shared medical decision making is the navigation of complex relationships between the physicians, patients, and surrogates who guide treatment plans for critically ill patients. This review of ethical issues in adult surgical critical care explores factors influencing interactions among the characters most prominently involved in health care decisions in the surgical intensive care unit: the patient, the surrogate, the surgeon, and the intensivist. Ethical tensions in the surgeon-patient relationship in the elective setting may arise from the preoperative surgical covenant and the development of surgical complications. Unlike that of the surgeon, the intensivist's relationship with the individual patient must be balanced with the need to serve other acutely ill patients. Due to their unique perspectives, surgeons and intensivists may disagree about decisions to pursue life-sustaining therapies for critically ill postoperative patients. Finally, although surrogates are asked to make decisions for patients on the basis of the substituted judgment or best interest standards, these models may underestimate the nuances of postoperative surrogate decision making. Strategies to minimize conflicts regarding treatment decisions are centered on early, honest, and consistent communication between all parties.

    OSA is a common, often chronic, condition requiring long-term therapy. Given the prevalence of OSA, as well as its significant health-related sequelae, a range of medical and surgical treatments have been developed and used with varying success depending on individual anatomy and patient compliance. Although CPAP is the primary treatment, many patients cannot tolerate this treatment and require alternative therapies. In this clinical scenario, surgery is often warranted and useful. Surgical management is aimed at addressing obstruction in the nasal, retropalatal, and retroglossal/hypopharyngeal regions, and many patients have multiple levels of obstruction. This review presents a comprehensive overview of research findings on a wide spectrum of surgical approaches currently used by sleep clinicians when other therapeutic modalities fail to achieve positive outcomes.

    Adult acquired flatfoot deformity is a progressive disorder with multiple symptoms and degrees of deformity. Stage II adult acquired flatfoot can be divided into stage IIA and IIB based on severity of deformity. Surgical procedures should be chosen based on severity as well as location of the flatfoot deformity. Care must be taken not to overcorrect the flatfoot deformity so as to decrease the possibility of lateral column overload as well as stiffness.

    Coarctation of the aorta (CoA), a juxtaductal obstructive lesion in the descending aorta and commonly associated with hypoplasia of the aortic arch occurs in 5-8% of patients with congenital heart disease. Since the initial surgical corrections in the 1950, surgical and transcatheter options have constantly evolved. Nowadays, transcatheter options are widely accepted as the initial treatment of choice in adults presenting with native or recurrent CoA. Surgical techniques are mainly reserved for patients with complex aortic arch anatomy such as extended arch hypoplasia or stenosis or para-CoA aneurysm formation. Extended aneurysms can be covered by conformable stents but stent implantation may require preparative vascular surgery. Complex re-CoA my best be treated by an ascending to descending bypass conduit. The following review aims to describe current endovascular and surgical practice pointing out modern developments and their limitations.

    Objective The pathophysiology of idiopathic Chiari malformation (CM) type 1 is disturbance of free cerebrospinal fluid (CSF) flow and restoration of normal CSF flow is the mainstay of treatment. Additional migration of the medulla oblongata in pediatric patients is referred to as CM type 1.5, but its significance in adult patients is unknown. This study is to compare surgical outcomes of adult idiopathic CM type 1.5 with that of type 1. Methods Thirty-eight consecutive adult patients (M : F=11 : 27; median, 33.5; range, 18–63) with syringomyelia due to idiopathic CM type 1 were reviewed. Migration of the medulla oblongata was noted in 13 patients. The modified McCormick scale (MMS) was used to evaluate functional status before and one year after surgery. All patients underwent foramen magnum decompression and duroplasty. Factors related to radiological success (≥50% decrease in the diameter of the syrinx) were investigated. The follow-up period was 72.7±55.6 months. Results Preoperative functional status were MMS I in 11 patients and MMS II in 14 of CM type 1 and MMS I in 8 and II in 5 of CM type 1.5. Of patients with MMS II, 5/14 patients in group A and 3/5 patients in group B showed improvement and there was no case of deterioration. Radiological success was achieved in 32 (84%) patients and restoration of the cisterna magna (p=0.01; OR, 46.5) was the only significant factor. Conclusion Migration of the medulla oblongata did not make a difference in the surgical outcome when the cisterna magna was restored. PMID:27651871

    Severe colitis, an umbrella encompassing several entities, is one of the most common acute gastrointestinal disorders resulting in critical illness. Clostridium difficile infection is responsible for the majority of nosocomial diarrhea with fulminant C difficile colitis (CDC) carrying a high mortality. Optimal outcomes can be achieved by early identification and treatment of fulminant CDC, with appropriate surgical intervention when indicated. Ischemic colitis, on the other hand, is uncommon with a range of etiological factors including abdominal aortic surgery, inotropic drugs, rheumatoid diseases, or often no obvious triggering factor. Most cases resolve with nonsurgical management; however, prompt recognition of full-thickness necrosis and gangrene is crucial for good patient outcomes. Fulminant colitis is a severe disease secondary to progressive ulcerative colitis with systemic deterioration. Surgical intervention is indicated for hemorrhage, perforation, or peritonitis and failure of medical therapy to control the disease. Although, failure of medical management is the most common indication, it can be difficult to define objectively and requires a collaborative multidisciplinary approach. This article proposes some simple management algorithms for these clinical entities, with a focus on critically ill patients.

  10. Intravenous fish oil in adult intensive care unit patients.

    2015-01-01

    Omega-3 fatty acids contained in fish oils have shown efficacy in the treatment of chronic and acute inflammatory diseases due to their pleiotropic effects on inflammatory cell signalling pathways. In a variety of experimental and clinical studies, omega-3 fatty acids attenuated hyperinflammatory conditions and induced faster recovery. This chapter will shed light on the effects of intravenous fish oil in adult intensive care unit (ICU) patients and will discuss clinical data and recent meta-analyses on the topic. While significant beneficial effects on infection rates and the lengths of ICU and hospital stays have concordantly been identified in three recent meta-analyses on non-ICU surgical patients, the level of evidence is not so clear for critically ill patients. Three meta-analyses published in 2012 or 2013 explored data on the ICU population. Although the present data suggest the consideration of enteral nutrition enriched with fish oil, borage oil and antioxidants in mild to severe acute respiratory distress syndrome, only one of the three meta-analyses found a trend (p = 0.08) of lower mortality in ICU patients receiving intravenous omega-3 fatty acids. Two of the meta-analyses indicated a significantly shorter hospital stay (5.17-9.49 days), and one meta-analysis found a significant reduction in ICU days (1.92). As a result of these effects, cost savings were postulated. Unlike in surgical patients, the effects of fish oil on infection rates were not found to be statistically significant in ICU patients, and dose-effect relationships were not established for any cohort. Thus, obvious positive secondary outcome effects with intravenous fish oil have not yet been shown to transfer to lower mortality in critically ill patients. There is a need for adequately powered, well-planned and well-conducted randomized trials to give clear recommendations on the individual utility and dosage of intravenous omega-3 fatty acids in critical illness.

    2014-01-01

    Purpose Evidence is emerging that delirium is associated with both short- and long-term morbidity and mortality. This review highlights the epidemiology, outcomes, prevention and treatment strategies associated with delirium after cardiac surgery. Recent findings The incidence of delirium after cardiac surgery is estimated to be 26-52%, with a significant percentage being hypoactive delirium. It is clear that without an appropriate structured test for delirium, the incidence of delirium will be under-recognized clinically. Delirium after cardiac surgery is associated with poor outcomes including increased long-term mortality, increased risk of stroke, poor functional status, increased hospital readmissions, and substantial cognitive dysfunction for 1-year following surgery. The effectiveness of prophylactic antipsychotics to reduce the risk of delirium is controversial, with data from recent small studies in non-cardiac surgery potentially showing a benefit. Although anti-psychotic medications are often used to treat delirium, the evidence that anti-psychotics in cardiac surgery patients reduce duration of delirium or improve long-term outcomes following delirium is poor. Summary Clinicians in the ICU must recognize the impact of delirium in predicting long-term outcomes for patients. Further research is needed in determining interventions that will be effective in preventing and treating delirium in cardiac surgical setting. PMID:24514034

    Introduction Although sodium disturbances are common in hospitalised patients, few studies have specifically investigated the epidemiology of sodium disturbances in the intensive care unit (ICU). The objectives of this study were to describe the incidence of ICU-acquired hyponatraemia and hypernatraemia and assess their effects on outcome in the ICU. Methods We identified 8142 consecutive adults (18 years of age or older) admitted to three medical-surgical ICUs between 1 January 2000 and 31 December 2006 who were documented to have normal serum sodium levels (133 to 145 mmol/L) during the first day of ICU admission. ICU acquired hyponatraemia and hypernatraemia were respectively defined as a change in serum sodium concentration to below 133 mmol/L or above 145 mmol/L following day one in the ICU. Results A first episode of ICU-acquired hyponatraemia developed in 917 (11%) patients and hypernatraemia in 2157 (26%) patients with an incidence density of 3.1 and 7.4 per 100 days of ICU admission, respectively, during 29,142 ICU admission days. The incidence of both ICU-acquired hyponatraemia (age, admission diagnosis, Acute Physiology and Chronic Health Evaluation (APACHE) II score, length of ICU stay, level of consciousness, serum glucose level, body temperature, serum potassium level) and ICU-acquired hypernatraemia (baseline creatinine, APACHE II score, mechanical ventilation, length of ICU stay, body temperature, serum potassium level, level of care) varied according to patients' characteristics. Compared with patients with normal serum sodium levels, hospital mortality was increased in patients with ICU-acquired hyponatraemia (16% versus 28%, p < 0.001) and ICU-acquired hypernatraemia (16% versus 34%, p < 0.001). Conclusions ICU-acquired hyponatraemia and hypernatraemia are common in critically ill patients and are associated with increased risk of hospital mortality. PMID:19094227

    The aims of this study were to test the hypotheses that the type of 3rd molar removal determines baseline pain and that baseline pain influences analgesic assay sensitivity. Three groups of patients were studied: (i) 100 patients that had one fully erupted maxillary 3rd molar extracted; (ii) 95 patients that had one lower impacted 3rd molar surgically removed; and (iii) 98 patients that had two ipsilateral impacted 3rd molars surgically removed. In a randomized, double-blind fashion, the patients received (every third hour, three times) either: (i) paracetamol 1g; (ii) paracetamol 1g plus codeine 60 mg; or (iii) placebo. Baseline pain intensity (100 mm Visual Analogue Scale) was significantly lower after extraction (8 mm (2-20)) (=median (25th -75th percentile) than after surgical removal of one 3rd molar (35 mm (15-57)), which was significantly lower than pain intensity after surgical removal of two 3rd molars (49 mm (24-82)). Analgesic effects of the active test drugs were superior to placebo. Paracetamol with and without codeine could be distinguished in patients after surgical removal of one 3rd molar. In conclusion, baseline pain was related to the degree of surgical trauma, but large inter-individual variation in baseline pain intensity reduced the ability to distinguish between paracetamol with and without codeine.

    Background The aim of this study was to examine the impact of somatic illnesses, electrolyte imbalance, red blood cell count, hypotension, and antipsychotic and opioid treatment on the duration of delirium in Central Intensive Care Unit for Surgery. Patients and methods Patients who were admitted to the Department of Central Intensive Care Unit for Surgery in the University Hospital Olomouc from February 2004 to November 2008 were evaluated using Riker sedation–agitation scale. Their blood pressure, heart rate, respiratory rate, and peripheral blood oxygen saturation were measured continually, and body temperature was monitored once in an hour. The laboratory blood tests including sodium, potassium, chlorides, phosphorus, urea and creatinine, hemoglobin, hematocrit, red and white blood cell count, and C-reactive protein, albumin levels and laboratory markers of renal and liver dysfunction were done every day. All measurements were made at least for ten consecutive days or longer until the delirium resolved. Results The sample consisted of 140 consecutive delirious patients with a mean age of 68.21±12.07 years. Delirium was diagnosed in 140 of 5,642 patients (2.48%) admitted in CICUS in the last 5 years. The median duration of delirium was 48 hours with a range of 12–240 hours. Statistical analysis showed that hyperactive subtype of delirium and treatment with antipsychotics were associated with prolonged delirium duration (hyperactive 76.15±40.53 hours, hypoactive 54.46±28.44 hours, mixed 61.22±37.86 hours; Kruskal–Wallis test: 8.022; P<0.05). The duration of delirium was significantly correlated also with blood potassium levels (Pearson’s r=0.2189, P<0.05), hypotension (hypotension 40.41±30.23 hours versus normotension 70.47±54.98 hours; Mann–Whitney U=1,512; P<0.05), administration of antipsychotics compared to other drugs (antipsychotics 72.83±40.6, benzodiazepines 42.00±20.78, others drugs, mostly piracetam 46.96±18.42 hours; Kruskal

Local epidemiological studies on sepsis are of paramount importance to increase our knowledge about sepsis features and to improve patient care and prognosis.Adult patients (≥20 years) admitted to the surgical intensive care units with severe sepsis or septic shock from 2009 to 2010 were retrospectively retrieved and analyzed. The primary outcome of interest was 28-day mortality.Of 7795 admissions, 536 (6.9%) patients had severe sepsis. The most common sites of infection were the respiratory tract (38%) and abdomen (33%). Gram-negative bacteria, particularly Klebsiella pneumoniae (8.6%) and Escherichia coli (6.0%), were the major infecting micro-organisms, responsible for approximately two-thirds of the severe sepsis episodes. The overall 28-day mortality rate was 61%, and a higher sequential organ failure assessment score and the use of mechanical ventilation were independently associated with a worse outcome.Admissions with severe sepsis are not uncommon and are associated with substantial 28-day mortality in surgical intensive care units in northern Taiwan. Establishment and optimization of each institutional sepsis care standard to improve the outcome of sepsis are warranted.

    Study Design Cross-sectional study with prospective recruitment Objective To determine the relationship of pain intensity (back and leg) on patients’ acceptance of surgical complication risks when deciding whether or not to undergo lumbar spinal fusion. Background To formulate informed decisions regarding lumbar fusion surgery, preoperative discussions should include a review of the risk of complications balanced with the likelihood of symptom relief. Pain intensity has the potential to influence a patient’s decision to consent to lumbar fusion. We hypothesized that pain intensity is associated with a patient’s acceptance of surgical complication risks. Methods Patients being seen for the first time by a spine surgeon for treatment of a non-traumatic or non-neoplastic spinal disorder completed a structured questionnaire. It posed 24 scenarios, each presenting a combination of risks of 3 complications (nerve damage, wound infection, nonunion) and probabilities of symptom relief. For each scenario, the patient indicated whether he/she would/would not consent to a fusion for low back pain (LBP). The sum of the scenarios in which the patient responded that he or she would elect surgery was calculated to represent acceptance of surgical complication risks. A variety of other data were also recorded, including age, gender, education level, race, history of non-spinal surgery, duration of pain, and history of spinal injections. Data were analyzed using bivariate analyses and multivariate regression analyses. Results The mean number of scenarios accepted by 118 enrolled subjects was 10.2 (median 8, standard deviation 8.5, range 0 to 24, or 42.5% of scenarios). In general, subjects were more likely to accept scenarios with lower risks and higher efficacy. Spearman’s rank correlation estimates demonstrated a moderate association between the LBP intensity and acceptance of surgical complication risks (r=0.37, p=0.0001) while leg pain intensity had a weak but positive

    Purpose To determine the role age plays in use of intensive care for patients who have major surgery. Materials and Methods Retrospective cohort study examining the association between age and admission to an intensive care unit (ICU) for all Medicare beneficiaries aged 65 or older who had a hospitalization for one of five surgical procedures: esophagectomy, cystectomy, pancreaticoduodenectomy (PD), elective open abdominal aortic aneurysm repair (open AAA), and elective endovascular AAA repair (endo AAA) from 2004–08. The primary outcome was admission to an ICU. Secondary outcomes were complications and hospital mortality. We used multi-level mixed-effects logistic regression to adjust for other patient and hospital-level factors associated with each outcome. Results The percentage of hospitalized patients admitted to ICU ranged from 41.3% for endo AAA to 81.5% for open AAA. In-hospital mortality also varied, from 1.1% for endo AAA to 6.8% for esophagectomy. After adjusting for other factors, age was associated with admission to ICU for cystectomy (Adjusted Odds Ratio (AOR) 1.56 (95% CI 1.36–1.78) for age 80–84+; 2.25 (1.85–2.75) age 85+ compared with age 65–69), PD (AOR 1.26 (1.06–1.50) age 80–84; 1.49 (1.11–1.99) age 85+) and esophagectomy (AOR 1.26 (1.02–1.55) age 80–84; 1.28 (0.91–1.80) age 85+). Age was not associated with use of intensive care for open or endo AAA. Older age was associated with increases in complication rates and in-hospital mortality for all five surgical procedures. Conclusions The association between age and use of intensive care was procedure-specific. Complication rates and in-hospital mortality increased with age for all five surgical procedures.

    Muscle weakness is common in the surgical intensive care unit (ICU). Low muscle mass at ICU admission is a significant predictor of adverse outcomes. The consequences of ICU-acquired muscle weakness depend on the underlying mechanism. Temporary drug-induced weakness when properly managed may not affect outcome. Severe perioperative acquired weakness that is associated with adverse outcomes (prolonged mechanical ventilation, increases in ICU length of stay, and mortality) occurs with persistent (time frame: days) activation of protein degradation pathways, decreases in the drive to the skeletal muscle, and impaired muscular homeostasis. ICU-acquired muscle weakness can be prevented by early treatment of the underlying disease, goal-directed therapy, restrictive use of immobilizing medications, optimal nutrition, activating ventilatory modes, early rehabilitation, and preventive drug therapy. In this article, the authors review the nosology, epidemiology, diagnosis, and prevention of ICU-acquired weakness in surgical ICU patients. PMID:26445385

    Abdominal surgery may affect intestinal absorption and the resulting levels of posaconazole in the blood. We measured plasma posaconazole levels in surgical intensive care unit (SICU) patients and tried to develop a predictive population pharmacokinetics model. A total of 270 samples from 15 patients receiving posaconazole via nasogastric tube were measured by high-performance liquid chromatography (HPLC). SICU patients showed lower plasma drug concentrations, a higher apparent clearance, and a higher volume of distribution than those in hematology patients, possibly due to poor absorption.

Severity of illness was measured with the Simplified Acute Physiology Score (SAPS) and the Quantified Therapeutic Intervention Scoring System (QTISS). Outcomes were evaluated with SICU length of stay (LOS), hospital LOS, SICU mortality, and hospital mortality. All patients admitted to an urban, tertiary-care SICU from August 1, 1986 to July 31, 1998 (12 years) were included. A total of 24,395 consecutive patients were evaluated of whom nine (0.037%) were age 100 or more. Complete outcome data were available for 13,773 patients who were divided into five groups on the basis of age: <70, 70 to 79, 80 to 89, 90 to 99, and 100 years and above. Nine centenarians were admitted to the SICU of whom one died in the SICU and another died in the hospital after SICU discharge (22.2% overall mortality). Centenarian patients had higher SAPS and QTISS on admission than patients in all other groups, although this difference was not significant because of the small number of centenarians. SICU and hospital LOS were not significantly longer for centenarians. Mortality in the SICU and hospital was significantly different across the age groups and rose with age. However, the modest 11.1 per cent SICU mortality rate in centenarians along with their LOS statistics indicate that these patients fare relatively well in surgical intensive care.

    Objective: Since the civilian war in Syria began, thousands of seriously injured trauma patients from Syria were brought to Turkey for emergency operations and/or postoperative intensive care. The aim of this study was to present the demographics and clinical features of the wounded patients in Syrian civil war admitted to the surgical intensive care units in a tertiary care centre. Methods: The records of 80 trauma patients admitted to the Anaesthesia, General Surgery and Neurosurgery ICUs between June 1, 2012 and July 15, 2014 were included in the study. The data were reviewed regarding the demographics, time of presentation, place of reference, Acute Physiology and Chronic Health Evaluation II (APACHE II) score and Injury Severity Score (ISS), surgical procedures, complications, length of stay and mortality. Results: A total of 80 wounded patients (70 males and 10 females) with a mean age of 28.7 years were admitted to surgical ICUs. The most frequent cause of injury was gunshot injury. The mean time interval between the occurrence of injury and time of admission was 2.87 days. Mean ISS score on admission was 21, and mean APACHE II score was 15.7. APACHE II scores of non-survivors were significantly increased compared with those of survivors (P=0.001). No significant differences was found in the age, ISS, time interval before admission, length of stay in ICU, rate of surgery before or after admission. Conclusion: The most important factor affecting mortality in this particular trauma-ICU patient population from Syrian civil war was the physiological condition of patients on admission. Rapid transport and effective initial and on-road resuscitation are critical in decreasing the mortality rate in civil wars and military conflicts. PMID:27375683

    With the six QSEN competencies woven throughout the baccalaureate nursing curriculum, which includes high-fidelity simulation, the aim of this research was to uncover deficits in QSEN-related clinical opportunities. Pre-licensure BSN nursing students enrolled in a sophomore-level medical-surgical rotation augmented with 25 percent simulation were observed directly, with time-on-task for each QSEN competency recorded and tabulated. The students were found to spend little time addressing several of the six competency areas in both clinical and simulation settings. Fully integrated classroom, simulation, and clinical experiences need to be considered in an effort to offer a full spectrum of QSEN-based knowledge and skill theory and practice for pre-licensure nursing students.

    This study which is a retrospective chart review aims to characterize the comorbidities associated with adult laryngotracheal stenosis and evaluate the relationship of these with stenosis grade, length, surgical interventions, and surgical intervals. Patients' demographics, medical and surgical comorbidities, grade of stenosis, quantity and degree of balloon dilations, dilation intervals, open airway procedures, and tracheotomy status were recorded from 2002 to 2012, at a tertiary voice and airway center. Surgical outcomes were evaluated in relation to patient comorbidities, stenosis quality, and surgical procedures. A total of 101 patients with laryngotracheal stenosis were examined with female patients comprising 71 % of the population. Seventeen patients (16.8 %) had idiopathic stenosis. Number of balloon dilations ranged from 0 to 24 (mean = 3.3). The average time between dilations was 38.4 weeks (range = 1.14-215.8 weeks). The patients with idiopathic stenosis were found to have a lower grade (p = 0.0066). Fifty-two patients (51.5 %) received a tracheotomy at one point during their management. The 14 patients (13.9 %) who remained tracheotomy dependent had a body mass index (BMI) of >30. No statistically significant correlation was found when the patients' age, BMI and comorbidites were compared with the grade of stenosis, number of balloon dilatations needed and other surgical interventions. On the other hand, interval in between surgeries was found to be longer in patients without an intubation history, and in idiopathic SGS (p = 0.004, p = 0.015, respectively). There was no significant relationship between surgical interval and gender, BMI, length of stenosis, grade (p = 0.059, p = 0.47, p = 0.97, p = 0.36, respectively). Airway stenosis in adults is complicated by the presence of multiple comorbidities. Better understanding of the etiology could aid in the prevention of the injury before it forms.

    2010-01-01

    Patients in the cardiothoracic surgical intensive care unit are generally critically ill and undergoing a systemic inflammatory response to cardiopulmonary bypass, ischemia/reperfusion, and hypothermia. This presents several metabolic challenges: hyperglycemia in need of intensive insulin therapy, catabolism, and uncertain gastrointestinal tract function in need of nutritional strategies. Currently, there are controversies surrounding the standard use of intensive insulin therapy and appropriate glycemic targets as well as the use of early enteral nutrition ± parenteral nutrition. In this review, an approach for intensive metabolic support in the cardiothoracic surgical intensive care unit is presented incorporating the most recent clinical evidence. This approach advocates an IIT blood glucose target of 80-110 mg/dL if, it can be implemented safely, with early nutrition support (using parenteral nutrition as needed) to prevent a critical energy debt.

    Night-time rest of the patients hospitalized in Intensive Care is a very important feature within the health/disease process since it has a direct repercussion on their adequate recovery. The objectives of this investigation are: 1) describe how the surgical patients perceive their night-time sleep in the Polyvalent Intensive Care Unit: 2) compare the subjective perception of the patients with the nursing record in the care plan and analyze the degree of agreement between both assessments. Night-time sleep has been studied in 104 patients; surgery patients from emergencies, patients who are intubated, with previous psychiatric treatment, sleep apnea, drinking habit or impossibility of adequate communication were not included. To measure the patient's perception, the five item sleep questionnaire of Richards-Campbell and the assessment of sleep by the nurse, as well as the remaining variables included in a computerized care plan, were used. The total mean score of the sleep on the first post-operative night was 51.42 mm. When the scores obtained in each one of the questionnaire items are analyzed, it is seen that the sleep profile of these patients has been characterized by being light sleep, with frequent wakenings and generally with little difficulty to go back to sleep when woke op or were awakened. The assessment of the night-time sleep performed by the nurse coincides with the perception of the patients on many occasions, and when there is discrepancy, the nurse has overestimated the patient's sleep.

    Adult acquired flatfoot deformity is a degenerative disease causing medial arch dysfunction. Surgical correction has typically involved tendon reconstruction with calcaneal osteotomy; however, the postoperative changes have not been fully characterized. The present study assessed the success of surgical correction of Stage IIb adult acquired flatfoot deformity through changes in plantar pressures and patient-generated outcome scores. With Institutional Review Board approval, 6 participants were evaluated before and after surgery using pedobarography, the Foot and Ankle Outcome Score, and the Medical Outcomes Study 36-item short-form questionnaire. The plantar pressures were recorded using a TekScan HRMat(®) during walking and in a 1- and 2-foot stance. The resulting contour maps were segmented into 9 regions, with the peak pressure, normalized force, and arch index calculated. Surgical effects were analyzed using paired t tests. Postoperatively, the Foot and Ankle Outcome Score and Medical Outcomes Study 36-item short-form questionnaire scores increased significantly from 180 ± 78 to 360 ± 136 (p < .03) and 47 ± 18 to 71 ± 19 (p = .06), respectively. During the 2-foot stance, the normalized force had increased significantly in the lateral midfoot (p < .03), although no significant differences were found in peak pressures. No significant differences were observed in the 1-foot stance. During walking, the normalized force increased significantly in the lateral mid- and forefoot (p < .05). The peak pressure increased significantly in the lateral forefoot (p < .01). The arch index values demonstrated no significant changes. The increased questionnaire scores indicated that surgical correction improved the self-perceived health of the participants. Lateral shifts in the peak pressure and normalized force suggest that forefoot and midfoot loading is altered postoperatively, consistent with the goal of offloading the dysfunctional arch. Thus, the present study has

    Arrhythmias are a major cause of morbidity, mortality and hospital admission in adults with congenital heart disease (CHD). The etiology of arrhythmias in this population is often multifactorial and includes electrical disturbances as part of the underlying defect, surgical intervention or hemodynamic abnormalities. Despite the numerous existing arrhythmia management tools including drug therapy, pacing and ablation, management of arrhythmias in adults with CHD remains difficult and challenging. Owing to improvement in mapping and ablation techniques, ablation and arrhythmia surgery are being performed more frequently in adults with CHD. However, there is little information on the long-term results of these treatment strategies. The purpose of this article is therefore to review the available data on nonpharmacological treatment of cardiac arrhythmias in adult patients with CHD and to give an overview of the available data on the early and late outcomes of these treatment strategies.

    Objective We compared the skeletal and dental changes that resulted from the use of two methods of intermaxillary fixation (IMF)-miniscrews and surgical archwire-in 74 adult patients who had Class III malocclusion and were treated with the same orthognathic surgical procedure at a hospital in Korea. Methods All the patients underwent Le Fort I osteotomy and bilateral sagittal split ramus osteotomy with rigid fixation. They were divided into two groups according to the type of IMF used-group 1 underwent surgical archwire fixation and group 2 underwent orthodontic miniscrew fixation. In a series of cephalograms for each patient, we compared vertical and horizontal tooth-position measurements: (a) immediately after surgery (T0), (b) 3 months after surgery (T1), and (c) 6 months after surgery (T2). Cephalometric changes within each group were examined using one-way analysis of variance (ANOVA) while the independent samples t-test procedure was used to compare the two groups. Results After surgery, the maxillary incisors tended to be proclined in both groups although there were no significant differences. Incisor overbite increased significantly in both groups from T0 to T1, and the miniscrew group (group 2) showed slightly greater overbite than the archwire group (group 1). Conclusions This study suggest that the use of orthodontic miniscrews and orthodontic surgical archwire for IMF in adult patients results in similar skeletal and dental changes. PMID:25667912

    Modified techniques for orthotopic heart transplantation are mandatory when complex congenital anomalies are associated in adult patients. An unusual case of a heterotaxy syndrome and dilated cardiomyopathy following mitral ring annuloplasty is presented in a 62-year-old male. Orthotopic cardiac transplantation was performed by using a modified operative strategy: selective peripheral and central venous cannulation according to the thoraco-abdominal venous challenges, biatrial technique, and preservation of venous drainage via the native coronary sinus. We discuss the anatomical features of heterotaxy in adult patients and surgical approaches when heart transplantation is needed. PMID:26450654

    OBJECTIVES--To describe the extent of variation in the case mix of adult admissions to general intensive care units in Britain and Ireland and investigate the impact of such variation on outcome. DESIGN--Prospective, cohort study of consecutive admissions to intensive care units. SETTING--26 general intensive care units in Britain and Ireland. SUBJECTS--9099 admissions to the intensive care units studied. MAIN OUTCOME MEASURE--Death or survival at discharge before and after adjustment of case mix (age, history of chronic conditions, surgical status, diagnosis, and severity of illness) according to the APACHE II method. RESULTS--Important differences in case mix were found, with large variations between the units. Hospital mortality was significantly associated with most of the case mix factors investigated. CONCLUSIONS--Comparing crude death rates in hospital between intensive care units may be misleading indicators of performance. The collection of data on case mix needs to be standardised and differences in case mix adjusted for when comparing outcome between different intensive care units. PMID:8241908

    Evaluation of the performance of the APACHE III (Acute Physiology and Chronic Health Evaluation) ICU (intensive care unit) and hospital mortality models at the Princess Alexandra Hospital, Brisbane is reported. Prospective collection of demographic, diagnostic, physiological, laboratory, admission and discharge data of 5681 consecutive eligible admissions (1 January 1995 to 1 January 2000) was conducted at the Princess Alexandra Hospital, a metropolitan Australian tertiary referral medical/surgical adult ICU ROC (receiver operating characteristic) curve areas for the APACHE III ICU mortality and hospital mortality models demonstrated excellent discrimination. Observed ICU mortality (9.1%) was significantly overestimated by the APACHE III model adjusted for hospital characteristics (10.1%), but did not significantly differ from the prediction of the generic APACHE III model (8.6%). In contrast, observed hospital mortality (14.8%) agreed well with the prediction of the APACHE III model adjusted for hospital characteristics (14.6%), but was significantly underestimated by the unadjusted APACHE III model (13.2%). Calibration curves and goodness-of-fit analysis using Hosmer-Lemeshow statistics, demonstrated that calibration was good with the unadjusted APACHE III ICU mortality model, and the APACHE III hospital mortality model adjusted for hospital characteristics. Post hoc analysis revealed a declining annual SMR (standardized mortality rate) during the study period. This trend was present in each of the non-surgical, emergency and elective surgical diagnostic groups, and the change was temporally related to increased specialist staffing levels. This study demonstrates that the APACHE III model performs well on independent assessment in an Australian hospital. Changes observed in annual SMR using such a validated model support an hypothesis of improved survival outcomes 1995-1999. PMID:12075637

    Summary Background The electronic health record (EHR) is increasingly viewed as a means to provide more coordinated, patient-centered care. Few studies consider the impact of EHRs on quality of care in the intensive care unit (ICU) setting. Objectives To evaluate key quality measures of a surgical intensive care unit (SICU) following implementation of the Epic EHR system in a tertiary hospital. Methods A retrospective chart review was undertaken to record quality indicators for all patients admitted to the SICU two years before and two years after EHR implementation. Data from the twelve-month period of transition to EHR was excluded. We collected length of stay, mortality, central line associated blood stream infection (CLABSI) rates, Clostridium difficile (C. diff.) colitis rates, readmission rates, and number of coded diagnoses. To control for variation in the patient population over time, the case mix indexes (CMIs) and APACHE II scores were also analyzed. Results There was no significant difference in length of stay, C. diff. colitis, readmission rates, or case mix index before and after EHR. After EHR implementation, the rate of central line blood stream infection (CLABSI) per 1 000 catheter days was 85% lower (2.16 vs 0.39; RR, 0.18; 95% CI, 0.05 to 0.61, p < .005), and SICU mortality was 28% lower (12.2 vs 8.8; RR, 1.35; 95% CI, 1.06 to 1.71, p < .01). Moreover, after EHR there was a significant increase in the average number of coded diagnoses from 17.8 to 20.8 (p < .000). Conclusions EHR implementation was statistically associated with reductions in CLABSI rates and SICU mortality. The EHR had an integral role in ongoing quality improvement endeavors which may explain the changes in CLABSI and mortality, and this invites further study of the impact of EHRs on quality of care in the ICU.

    Procalcitonin test (PCT) has been proposed to check severity of generalized infections or sepsis. The authors measured the PCT values with PCT-Q quick test (BRAHMS DIAGNOSTICA GmbH, Berlin) at 14 surgical patients treated in their intensive care unit (7 sepsis, 4 peritonitis, 2 localized pancreatic abscess, 1 postoperative fever). At 3 septic patients (2 pancreatitis, 1 intestinal necrosis) they measured the PCT levels repeatedly during treatment. In 2 patients with localized pancreatic abscess and in 1 patient with postoperative fever without evidence of infection the PCT levels were low (< 0.5 ng/ml). At 4 patients with peritonitis following gastric or colon perforation the PCT levels were highly elevated (> 10 ng/ml). At 7 patients with severe sepsis the PCT values were high (> 2 ng/ml), except for 1 patient with intestinal necrosis. At this patient the PCT levels were repeatedly low. In 2 septic patients with pancreatitis elevated PCT levels indicated the need for surgery. In most patients PCT was a good indicator of generalized infections. PCT levels measured repeatedly in sepsis were lower than in patients with peritonitis.

    Objective To describe rounding practices in Canadian adult Intensive Care Units (ICU) and identify opportunities for improvement. Design Mixed methods design. Cross sectional survey of Canadian Adult ICUs (n = 180) with purposefully sampled follow-up interviews (n = 7). Measurements and Main Results Medical directors representing 111 ICUs (62%) participated in the survey. Rounding practices varied across ICUs with the majority reporting the use of interprofessional rounds (81%) that employed an open (94%) and collaborative (86%) approach, occurred at the patient’s bedside (82%), and started at a standard time (79%) and standard location (56%). Most participants reported that patients (83%) and family members (67%) were welcome to attend rounds. Approximately half of ICUs (48%) used tools to facilitate rounds. Interruptions during rounds were reported to be common (i.e., ≥1 interruption for ≥50% of patients) in 46% of ICUs. Four themes were identified from qualitative analysis of participant responses to open-ended survey questions and interviews: multidisciplinarity, patient and family involvement, factors influencing productivity, and teaching and learning. Conclusions There is considerable variation in current rounding practices in Canadian medical/surgical ICUs. Opportunities exist to improve ICU rounds including ensuring the engagement of essential participants, clearly defining participant roles, establishing a standardized approach to the rounding process, minimizing interruptions, modifying the role of teaching, utilizing a structured rounding tool, and developing a metric for measuring rounding quality.

Data sources Medline, EMBASE, CINAHL and Cochrane database up to 2008. Hand searches of journals and websites. Selection of studies Studies evaluated guidelines for referral from primary to secondary care, for elective surgical assessment for adults. Outcome measures Appropriateness of referral (usually measured as guideline compliance) including clinical appropriateness, appropriateness of destination and of pre-referral management (eg, diagnostic investigations), general practitioner knowledge of referral appropriateness, referral rates, health outcomes and costs. Results 24 eligible studies (5 randomised control trials, 6 cohort, 13 case series) included guidelines from UK, Europe, Canada and the USA for referral for musculoskeletal, urological, ENT, gynaecology, general surgical and ophthalmological conditions. Interventions varied from complex (“one-stop shops”) to simple guidelines. Four randomized control trials reported increases in appropriateness of pre-referral care (diagnostic investigations and treatment). No evidence was found for effects on practitioner knowledge. Mixed evidence was reported on rates of referral and costs (rates and costs increased, decreased or stayed the same). Two studies reported on health outcomes finding no change. Conclusions Guidelines for elective surgical referral can improve appropriateness of care by improving pre-referral investigation and treatment, but there is no strong evidence in favour of other beneficial effects.

    Outpatient surgical procedures for adult hip and knee reconstruction are gaining interest on a worldwide basis and have been progressively increasing over the last few years. Preoperative screening needs to concentrate on both the patient's comorbidities and home environment to provide a proper alignment of expectations of the surgeon, the patient, and the patient's family. Preoperative multidisciplinary patient information covering all aspects of the upcoming treatment course is a mandatory step, focusing on pain management and early mobilization. Perioperative pain management includes both multimodal and preventive analgesia. Preemptive medications, minimization of narcotics, and combination of general and regional anesthesia are the techniques required in joint arthroplasty performed as an outpatient surgical procedure. A multimodal blood loss management program should be used with preoperative identification of anemia and attention directed toward minimizing blood loss, considering the use of tranexamic acid during the surgical procedure. Postoperative care extends from the initial recovery from anesthesia to the physical therapist's evaluation of the patient's ambulatory status. After the patient has met the criteria for discharge and has been discharged on the same day of the surgical procedure, a nurse should call the patient later at home to check on wound status, pain control, and muscle weakness, which will be further addressed by physiotherapy and education. Implementing outpatient arthroplasty requires monitoring safety, patient satisfaction, and economic impact. PMID:27385689

    AIM: To evaluate the impact of an enteral feeding protocol on administration of nutrition to surgical intensive care unit (SICU) patients. METHODS: A retrospective chart review was conducted on patients initiated on enteral nutrition (EN) support during their stay in a 14 bed SICU. Data collected over a seven-day period included date of tube feed initiation, rate initiated, subsequent hourly rates, volume provided daily, and the nature and length of interruptions. The six months prior to implementation of the feeding protocol (pre-intervention) and six months after implementation (post-intervention) were compared. One hundred and four patients met criteria for inclusion; 53 were pre-intervention and 51 post-intervention. RESULTS: Of the 624 patients who received nutrition support during the review period, 104 met the criteria for inclusion in the study. Of the 104 patients who met criteria outlined for inclusion, 64 reached the calculated goal rate (pre = 28 and post = 36). The median time to achieve the goal rate was significantly shorter in the post-intervention phase (3 d vs 6 d; P = 0.01). The time to achieve the total recommended daily volume showed a non-significant decline in the post-intervention phase (P = 0.24) and the overall volume administered daily was higher in the post-intervention phase (61.6% vs 53.5%; P = 0.07). While the overall interruptions data did not reach statistical significance, undocumented interruptions (interruptions for unknown reasons) were lower in the post-intervention phase (pre = 23/124, post = 9/96; P = 0.06). CONCLUSION: A protocol delineating the initiation and advancement of EN support coupled with ongoing education can improve administration of nutrition to SICU patients. PMID:27652209

    Background Hypo-magnesemia is described to occur in as many as 65% of intensive care unit (ICU) patients. Magnesium (Mg) is a cofactor in over 300 enzymatic reactions involving energy metabolism, protein, and nucleic acid synthesis. The membrane pump that creates the electrical gradient across the cell membrane is dependent on Mg, and it is important in the activity of electrically excitable tissues. Since Mg regulates the movement of calcium in smooth muscle cells, it is also important in peripheral vascular tone and blood pressure. Studies have linked hypo-magnesemia to multiple chronic diseases and to a higher mortality rate. Methods To explore trends within our own tertiary care surgical ICU, we sampled our patients’ laboratory records in 2001 and in 2011. Hypo-magnesemia in our ICU is defined as an Mg less than 2.0 mg/dL. Results This retrospective review of all SICU patients from October to December revealed that there was a significant increase (P < 0.01) in the patients with their serum Mg level measured between 2001 (89%) and 2011 (95%). There was a significant decrease (P < 0.001) in patients with hypomagnesemia (< 2 mg/dL) between 2001 (47.5%) and 2011 (33.0%). On the other hand, there was a significant increase (P < 0.001) in patients with normal serum Mg level (> 2 mg/dL) between 2001 (52.5%) and 2011 (67.0%). Conclusions There was not only more monitoring of Mg in 2011, but a lower incidence of hypo-Mg compared to 2001. Possible explanations include changing patterns of antibiotic and diuretic use, less amphotericin use, more frequent laboratory surveillance, and better trained ICU practitioners. PMID:25699122

    The advancement of perioperative medicine is leading to greater diversity in development of pre-surgical interventions, implemented to reduce patient surgical risk and enhance post-surgical recovery. Of these interventions, the prescription of pre-operative exercise training is gathering momentum as a realistic means for enhancing patient surgical outcome. Indeed, the general benefits of exercise training have the potential to pre-operatively optimise several pre-surgical risks factors, including cardiorespiratory function, frailty and cognitive function. Any exercise programme incorporated into the pre-operative pathway of care needs to be effective and time efficient in that any fitness gains are achievable in the limited period between the decision for surgery and operation (e.g. 4 weeks). Fortunately, there is a large volume of research describing effective and time-efficient exercise training programmes within the discipline of sports science. Accordingly, the objective of our commentary is to synthesise contemporary exercise training research, both from non-clinical and clinical populations, with the overarching aim of informing the development of effective and time-efficient pre-surgical exercise training programmes. The development of such exercise training programmes requires the careful consideration of several key principles, namely frequency, intensity, time, type and progression of exercise. Therefore, in light of more recent evidence demonstrating the effectiveness and time efficiency of high-intensity interval training-which involves brief bouts of intense exercise interspersed with longer recovery periods-the principles of exercise training programme design will be discussed mainly in the context of such high-intensity interval training programmes.

    To clarify the special instruments and equipment used for minimally invasive cardiac surgery (MICS), we examined the initial experiences with MICS operations with ministernotomy or minithoracotomy at our institution. Fifty adult patients with congenital, valvular, and/or ischemic heart diseases underwent MICS operations, and all surgical procedures were completed without conversion to full sternotomy. The length of the skin incision was about 10 cm or less in all patients. Postoperative recovery was favorable, and the majority of the patients were discharged from the hospital around the end of the second postoperative week. In this series of patients, an oscillating bone saw, lifting type retractor, 2 blade spreader, cannula with a balloon, and right-angled aortic clamp among other items, were very useful for successfully performing various operations with MICS approaches and techniques. The associated results suggest that MICS with ministernotomy or minithoracotomy was feasible using special instruments and equipment and could be encouraged for adult patients with various cardiovascular diseases.

    Adult degenerative scoliosis associated with lumbar stenosis has become a common issue in the elderly population. But its surgical management is on debating. The main issue condenses on the management priority of scoliosis or stenosis. This study is to investigate surgical management strategy and outcome of adult degenerative scoliosis associated with lumbar stenosis. Between January 2003 and December 2010, 108 patients were admitted to the authors' institution for adult degenerative scoliosis associated with lumbar stenosis. They were divided into 3 groups based on the symptom. Then the surgical management was carried out. The clinical outcome was evaluated according to the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 score (SRS-22 score) at follow up. Group 1 was with primary lumbar stenosis symptom, local decompression and short fusion were performed. Group 2 was with compensated spinal imbalance symptom, local decompression of the symptomatic spinal stenosis and short fusion were performed. Group 3 was with primary spinal imbalance, correction surgery and long fusion were performed. For Group 1, the ODI scores declined from 62.5 ± 4.2 preoperatively to 21.8 ± 2.5 at final follow up, the SRS-22 scores decreased from 44.8 ± 3.2 preoperatively to 70.9 ± 6.0 at final follow up.

    The aim of this study was to evaluate the usefulness of using Acute Physiology and Chronic Health Evaluation (APACHE) II score and Sequential Organ Failure Assessment (SOFA) score as the predictors of length of stay (LOS) in various surgical intensive care units (ICUs) and to test the hypothesis that the significance of scoring for predicting LOS is greater in specialized surgical ICUs. We scored patients in a non-specialized general surgical ICU (n = 328) and in a specialized cardiosurgical ICU (n = 158) consecutively on admission (APACHE II-1st day; SOFA-1st day) and on third day of stay (APACHE II-3rd day; SOFA-3rd day) in a 4-month period. LOS and APACHE II/SOFA scores were significantly correlated both on admission and on third day of stay in the general surgical ICU (APACHE II-1st day r = 0.289; SOFA-1st day r = 0.306; APACHE II-3rd day r = 0.728; SOFA-3rd day r = 0.725). LOS and APACHE II on admission were not significantly correlated in the cardiosurgical ICU (APACHE II-1st day r = 0.092), while SOFA on admission and APACHE II and SOFA on third day were significantly correlated (SOFA-1st day r = 0.258; APACHE II-3rd day r = 0.716; SOFA-3rd day r = 0.719). Usefulness of scoring for predicting LOS in ICU varied between different surgical ICUs. Contrary to our hypothesis, scoring had greater value for predicting LOS in the non-specialized general surgical ICU. APACHE II score on admission had no value for predicting LOS in the cardiosurgical ICU.

    The need exists for a simplified and ecomonical computer based monitoring system for critically ill surgical patients. Such a system would enjoy widespread use in surgical intensive care units in regional, as well as larger community hospitals. We have assembled such a system which provides digital readout of the usual physiologic parameters, and also provide computer storage of accumulated data for review and evaluation of patient care. The computer provides graphic and digital display and digital printout for subsequent inclusion in the patient records. Most frequent indications for this system include the development of acute respiratory insufficiency or acute circulatory failure due to invasive sepsis and/or severe arteriosclerotic cardiovascular disease. Information most beneficial in patient care included measurement of cardiac output;alveolar arterial oxygen gradient. ImagesFigure 1Figure 5Figure 9Figure 11

    Although acute myeloid leukemia (AML) is primarily a disease of older adults (age ≥60 years), the optimal treatment for older adults remains largely undefined. Intensive chemotherapy is rarely beneficial for frail older adults or those with poor-risk disease, but criteria that define fitness and/or appropriateness for intensive chemotherapy remain to be standardized. Evaluation of disease-related and patient-specific factors in the context of clinical decision making has therefore been largely subjective. A uniform approach to identify those patients most likely to benefit from intensive therapies is needed. Here, we review currently available objective measures to define older adults with AML who are ineligible for intensive chemotherapy, and discuss promising investigational approaches. PMID:26697412

    Using the concepts in the Fogg Behavioral Model, 37 volunteers aged 50 and older described their preparation for intensive volunteering with faith-based organizations. Their multistage preparation process included decision points where respondents needed to choose whether to drop out or continue preparation. Ability was a stronger determinant of serving than motivation, particularly in terms of health and finances. This model can facilitate understanding of the barriers to volunteering and aid organizations in tailoring support at crucial points for potential older volunteers in intensive service.

    Most reports of coronary artery bypass grafting in adult patients with dextrocardia have focused on the surgeon's position with respect to the operating table. Herein, we describe the cases of 2 patients with dextrocardia who underwent surgery at our own institution, then discuss preoperative evaluation, surgical approaches, and patient outcomes that have been reported in the medical literature. Whereas most patients, including ours, have presented with classic situs inversus totalis and dextrocardia, a few patients have had other associated anomalies or atypical morphologic conditions. Careful imaging, and perhaps cardiac catheterization, is required. Particular attention should be paid to cannulation technique and conduits that can best be used within the altered orientation of the heart. Morbidity rates in these revascularized patients seem comparable with those in coronary artery bypass patients whose coronary anatomy is normal. Anatomic variants in dextrocardia are important from the surgical viewpoint due to the increasing population of patients with repaired congenital heart disease who reach adulthood, and in whom other cardiac defects and abnormalities of cardiac position are common.

    OBJECTIVES: (a) To assess the impact of HIV status (HIV negative, HIV positive, AIDS) on the outcome of patients admitted to intensive care units for diseases unrelated to HIV; (b) to decide whether a positive test result for HIV should be a criterion for excluding patients from intensive care for diseases unrelated to HIV. DESIGN: A prospective double blind study of all admissions over six months. HIV status was determined in all patients by enzyme linked immunosorbent assay (ELISA), immunofluorescence assay, western blotting, and flow cytometry. The ethics committee considered the clinical implications of the study important enough to waive patients' right to informed consent. Staff and patients were blinded to HIV results. On discharge patients could be advised of their HIV status if they wished. SETTING: A 16 bed surgical intensive care unit. SUBJECTS: All 267 men and 135 women admitted to the unit during the study period. INTERVENTIONS: None. MAIN OUTCOME MEASURES: APACHE II score (acute physiological, age, and chronic health evaluation), organ failure, septic shock, durations of intensive care unit and hospital stay, and intensive care unit and hospital mortality. RESULTS: No patient had AIDS. 52 patients were tested positive for HIV and 350 patients were tested negative. The two groups were similar in sex distribution but differed significantly in age, incidence of organ failure (37 (71%) v 171 (49%) patients), and incidence of septic shock (20 (38%) v 54 (15%)). After adjustment for age there were no differences in intensive care unit or hospital mortality or in the durations of stay in the intensive care unit or hospital. CONCLUSIONS: Morbidity was higher in HIV positive patients but there was no difference in mortality. In this patient population a positive HIV test result should not be a criterion for excluding a patient from intensive care. PMID:9133887

    The aim of the study was to compare the pain-relieving effect and the time spent in the recovery ward after treatment with high-frequency, high-intensity transcutaneous electrical nerve stimulation (TENS) or intravenous (IV) conventional pharmacological treatment after surgical abortion. Two-hundred women who underwent surgical abortion and postoperatively reported a visual analogue scale (VAS) pain score3 were included. The patients were randomised to TENS or conventional pharmacological treatment for their postoperative pain. The TENS treatment was given with a stimulus intensity between 20 and 60 mA during 1 min and repeated once if insufficient pain relief (VAS3). In the conventional pharmacological treatment group, a maximum dose of 100 microg fentanyl was given IV. There was no difference between the groups with regard to pain relief according to the VAS pain score (TENS=VAS 1.3 vs. IV opioids=VAS 1.6; p=0.09) upon discharge from the recovery ward. However, the patients in the TENS group spent shorter time (44 min) in the recovery ward than the conventional pharmacological treatment group (62 min; p<0.0001). The number of patients who needed additional analgesics in the recovery ward was comparable in both groups, as was the reported VAS pain score upon leaving the hospital (TENS=2.0 vs. conventional pharmacological treatment=1.8, NS). These results suggest that the pain-relieving effect of TENS seems to be comparable to conventional pharmacological treatment with IV opioids. Hence, TENS may be a suitable alternative to conventional pain management with IV opioids after surgical abortion.

    PubMed

    Trilla, A

    1994-07-01

    Patients in intensive care units (ICUs) are a small subgroup of all hospitalized patients, but they account for approximately 25% of all hospital infections. Nosocomial infection rates among ICU patients are 5-10 times higher than among general ward patients. ICU infection rates are higher due to complex interactions between the patients' underlying disease, severity of illness, type of ICU, duration of stay, and invasive devices used. Antimicrobial resistance is a major clinical problem despite potent and newer antibiotics. Organisms that pose a clinically significant resistance problem among ICU patients include methicillin-resistant staphylococci, enterococci, a wide variety of enterobacteriaceae, Pseudomonas aeruginosa, Pseudomonas cepacia, Xanthomonas maltophila, Acinetobacter and Candida species. Traditional infection control measures include identification of reservoirs, halting transmission between patients, stopping progression from colonization to infection and modifying host risk. In addition, sound selection procedures and guidelines for antibiotic usage are necessary to control the spread of multi-resistant micro-organisms.

    This study compared prophylactic administration of either intragastric misoprostol (200 micrograms four times a day), a prostaglandin E1 analog, or bolus intravenous cimetidine (300 mg every 6 hours) in preventing stress lesions and stress bleeding in 127 adult postoperative patients who required mechanical ventilation and also had developed hypotension or sepsis. Both drug treatments were equally effective in preventing the development of diffuse gastritis (greater than 10 gastric hemorrhagic lesions) and in preventing upper gastrointestinal hemorrhage (UGIH). The combined data from both groups showed that for the 44 (35%) patients who died, death was significantly associated with the presence at study entry of renal failure (64% of 25 patients with renal failure died), hepatic failure (57% of 23 patients) or coagulopathy (62% of 29 patients) (p less than 0.02 for each), and with the number of organ system failures at study entry (48% of 69 patients with multiple organ system failures died, p less than 0.001). Death was also significantly associated with the presence of adult respiratory distress syndrome (ARDS) at study entry or the development of ARDS (63% of 24 patients with ARDS died, p less than 0.001), and the development of UGIH (5% of 93 patients with known bleeding outcome died, p less than 0.05). The number of stress lesions that developed was significantly associated with subsequent UGIH (p less than 0.001). Additional organ system failure developed during the study in 31% of the 127 patients, as did diffuse gastritis in 20% of 111 patients who had a follow-up endoscopy. These results demonstrate that postoperative patients who require mechanical ventilation and have hypotension or sepsis are at significant risk for the development of stress gastric lesions and multiple organ system failure even when prophylaxis for stress ulcers is provided. Furthermore, the presence of ARDS, renal failure, hepatic failure, coagulopathy, and UGIH are significantly

    Objectives Antioxidant depletion is common in critically ill patients. This study was designed to determine the effects of PN, with or without glutamine (Gln) supplementation, on systemic antioxidant status in adult patients after major surgery who required parenteral nutrition (PN) in the surgical intensive care unit (SICU) setting. Methods Fifty-nine SICU patients who required PN following pancreatic surgery or cardiac, vascular or colonic (non-pancreatic) surgery were randomized in a double-blind study to receive standard PN (Gln-free) or Gln-supplemented PN (Gln-PN) in which Gln was provided as alanyl-Gln dipeptide. Conventional PN vitamin and mineral doses were administered to all subjects. Plasma concentrations of the antioxidant glutathione (GSH) and the anti-oxidant nutrients α-tocopherol, vitamin C and zinc were determined at baseline (initiation of study PN) and again after 7 days of study PN. Data were analyzed for the total study cohort and within the pancreatic surgery and non-pancreatic (cardiac, vascular and colonic) surgery patient subgroups. Results Mean plasma antioxidant concentrations were within or slightly below the normal ranges at baseline. However, a high percentage of patients demonstrated below normal baseline plasma concentrations of GSH (59%), vitamin C (59%) and zinc (68%), respectively. A lower percentage of patients exhibited below normal plasma α-tocopherol levels (21%). Study PN significantly improved plasma zinc levels in the entire study group and each surgical subgroup. Gln-PN significantly improved the change in plasma reduced GSH from baseline to day 7 in the non-pancreatic surgery patients (PN: −0.27 µM vs Gln-PN: +0.26 µM; p<0.03). Conclusions Low plasma levels of key antioxidants were common in this group of SICU patients despite administration of PN containing conventional micronutrients. Compared to standard PN, Gln-supplemented PN improved plasma GSH levels in SICU patients after cardiac, vascular or colonic

    The traditional approach to the care of the gastrointestinal tract in the intensive care unit has been one of neglect. However, recent evidence has linked enteric flora to the generation of clinical sepsis in the absence of other infectious foci. The role of the bowel as an efficient barrier to the invasion of its own flora is addressed in this paper. A variety of insults disrupt the integrity of the barrier function of the gut, allowing the entry of bowel organisms or endotoxins, or both, into the portal and systemic circulatory systems. In animal and early clinical studies, a number of interventions, aimed at altering the enteric flora and enhancing the bowel's barrier function, have been shown to modulate the host's resistance to different insults and may even improve clinical outcome. Such interventions include maintenance of enteral feeding, glutamine supplementation of hyperalimentation solutions and selective bacterial decontamination of the bowel.

    Preparation for replacing the large proportion of staff nurses reaching retirement age in the next few decades in the United States is essential to continue delivering high-quality nursing care and improving patient outcomes. Retaining experienced critical care nurses is imperative to successfully implementing the orientation of new inexperienced critical care nurses. It is important to understand factors that affect work engagement to develop strategies that enhance nurse retention and improve the quality of patient care. Nurses' experience of moral distress has been measured in medical intensive care units but not in surgical trauma care units, where nurses are exposed to patients and families faced with sudden life-threatening, life-changing patient consequences.This pilot study is a nonexperimental, descriptive, correlational design to examine the effect of compassion satisfaction, compassion fatigue, moral distress, and level of nursing education on critical care nurses' work engagement. This is a partial replication of Lawrence's dissertation. The study also asked nurses to describe sources of moral distress and self-care strategies for coping with stress. This was used to identify qualitative themes about the nurse experiences. Jean Watson's theory of human caring serves as a framework to bring meaning and focus to the nursing-patient caring relationship.A convenience sample of 26 of 34 eligible experienced surgical intensive care unit trauma nurses responded to this survey, indicating a 77% response rate. Twenty-seven percent of the nurses scored high, and 73% scored average on compassion satisfaction. On compassion fatigue, 58% scored average on burnout and 42% scored low. On the secondary traumatic stress subscale, 38% scored average, and 62% scored low. The mean moral distress situations subscale score was 3.4, which is elevated. The mean 9-item Utrecht Work Engagement Scale total score, measuring work engagement, was 3.8, which is considered low

    rapid ultrasound examination performed by an experienced examiner can potentially alter the traditional diagnostic algorithm in which magnetic resonance arthrography remains the gold standard. PERIACETABULAR OSTEOTOMY FOR SURGICAL TREATMENT OF HIP DYSPLASIA IN ADULTS: Encouraging hip joint survival and clinical outcome were reported at medium-term follow-up after periacetabular osteotomy. The small number of studies reporting the outcome beyond a 5-year follow-up is in contrast to the wide application of the periacetabular osteotomy. The performed analysis of predictors of conversion to total hip replacement following periacetabular osteotomy documented the importance of different biomechanical and degenerative factors. Knowledge about factors predicting early conversion to total hip replacement has the potential to refine patient selection and to improve treatment by periacetabular osteotomy. Cartilage thickness was documented to be preserved up to 2,5 years after periacetabular osteotomy. All but 1 hip joint had acetabular labral tears, thus indicating that the presence of labral tears does not accelerate cartilage degeneration after periacetabular osteotomy. PMID:22677250

    Background: Nosocomial infections (NIs) in the postoperative period not only increase morbidity and mortality, but also impose a significant economic burden on the health care infrastructure. This retrospective study was undertaken to (a) evaluate the incidence, characteristics, risk factors and outcomes of NIs and (b) identify common microorganisms responsible for infection and their antibiotic resistance profile in our Cardiac Surgical Intensive Care Unit (CSICU). Patients and Methods: After ethics committee approval, the CSICU records of all patients who underwent cardiovascular surgery between January 2013 and December 2014 were reviewed retrospectively. The incidence of NI, distribution of NI sites, types of microorganisms and their antibiotic resistance, length of CSICU stay, and patient-outcome were determined. Results: Three hundred and nineteen of 6864 patients (4.6%) developed NI after cardiac surgery. Lower respiratory tract infections (LRTIs) accounted for most of the infections (44.2%) followed by surgical-site infection (SSI, 11.6%), bloodstream infection (BSI, 7.5%), urinary tract infection (UTI, 6.9%) and infections from combined sources (29.8%). Acinetobacter, Klebsiella, Escherichia coli, and Staphylococcus were the most frequent pathogens isolated in patients with LRTI, BSI, UTI, and SSI, respectively. The Gram-negative bacteria isolated from different sources were found to be highly resistant to commonly used antibiotics. Conclusion: The incidence of NI and sepsis-related mortality, in our CSICU, was 4.6% and 1.9%, respectively. Lower respiratory tract was the most common site of infection and Gram-negative bacilli, the most common pathogens after cardiac surgery. Antibiotic resistance was maximum with Acinetobacter spp. PMID:27052070

    This study determined the contribution of supraspinal fatigue and contractile properties to the age difference in neuromuscular fatigue during and recovery from a low-intensity sustained contraction. Cortical stimulation was used to evoke measures of voluntary activation and muscle relaxation during and after a contraction sustained at 20% of maximal voluntary contraction (MVC) until task failure with elbow flexor muscles in 14 young adults (20.9 ± 3.6 yr, 7 men) and 14 old adults (71.6 ± 5.4 yr, 7 men). Old adults exhibited a longer time to task failure than the young adults (23.8 ± 9.0 vs. 11.5 ± 3.9 min, respectively, P < 0.001). The time to failure was associated with initial peak rates of relaxation of muscle fibers and pressor response (P < 0.05). Increments in torque (superimposed twitch; SIT) generated by transcranial magnetic stimulation (TMS) during brief MVCs, increased during the fatiguing contraction (P < 0.001) and then decreased during recovery (P = 0.02). The increase in the SIT was greater for the old adults than the young adults during the fatiguing contraction and recovery (P < 0.05). Recovery of MVC torque was less for old than young adults at 10 min post-fatiguing contraction (75.1 ± 8.7 vs. 83.6 ± 7.8% of control MVC, respectively, P = 0.01) and was associated with the recovery of the SIT (r = -0.59, r(2) = 0.35, P < 0.001). Motor evoked potential (MEP) amplitude and the silent period elicited during the fatiguing contraction increased less for old adults than young adults (P < 0.05). The greater fatigue resistance with age during a low-intensity sustained contraction was attributable to mechanisms located within the muscle. Recovery of maximal strength after the low-intensity fatiguing contraction however, was impeded more for old adults than young because of greater supraspinal fatigue. Recovery of strength could be an important variable to consider in exercise prescription of old populations.

    We retrospectively analyzed 63 patients (31 males and 32 females) with arachnoid cysts managed over a 15 year period at our institution. Surgical indications and modalities for the treatment of intracranial arachnoid cysts are controversial, although endoscopic fenestration is often recommended as a standard procedure. In our cohort, clinical postoperative results and radiological assessments based on the presenting symptoms, cyst location, cyst volume and surgical modalities were recorded. The most common symptoms included headaches (66.7%), dizziness (46%) and seizures (36.5%). Cyst wall excision with microsurgical craniotomy was carried out in 28 patients (44.4%), cyst fenestration in 16 (25.4%), cystoperitoneal or ventriculoperitoneal shunting in 15 (23.8%) and endoscopic fenestration in four patients (6.3%). A satisfactory clinical outcome was achieved in 51 patients (80.9%) and cyst reduction was achieved in 49 (77.8%), at the last follow-up. Clinical improvement correlated significantly with volume reduction in patients with suprasellar and infratentorial cysts (r=0.495; p=0.022) while a similar result was not found after surgery in patients with frontal and temporal cysts. Surgical complications were not correlated with surgical modalities, occurring in only seven patients (11.1%). The various surgical modalities did not influence outcomes. Patients with nonspecific symptoms such as headache may obtain favourable outcomes from surgical treatment with no severe complications, although, intracranial hypertension and neurological deficits are more definite surgical indications for arachnoid cysts.

    OBJECTIVE To analyze the incremental cost-utility ratio for the surgical treatment of hip fracture in older patients. METHODS This was a retrospective cohort study of a systematic sample of patients who underwent surgery for hip fracture at a central hospital of a macro-region in the state of Minas Gerais, Southeastern Brazil between January 1, 2009 and December 31, 2011. A decision tree creation was analyzed considering the direct medical costs. The study followed the healthcare provider’s perspective and had a one-year time horizon. Effectiveness was measured by the time elapsed between trauma and surgery after dividing the patients into early and late surgery groups. The utility was obtained in a cross-sectional and indirect manner using the EuroQOL 5 Dimensions generic questionnaire transformed into cardinal numbers using the national regulations established by the Center for the Development and Regional Planning of the State of Minas Gerais. The sample included 110 patients, 27 of whom were allocated in the early surgery group and 83 in the late surgery group. The groups were stratified by age, gender, type of fracture, type of surgery, and anesthetic risk. RESULTS The direct medical cost presented a statistically significant increase among patients in the late surgery group (p < 0.005), mainly because of ward costs (p < 0.001). In-hospital mortality was higher in the late surgery group (7.4% versus 16.9%). The decision tree demonstrated the dominance of the early surgery strategy over the late surgery strategy: R$9,854.34 (USD4,387.17) versus R$26,754.56 (USD11,911.03) per quality-adjusted life year. The sensitivity test with extreme values proved the robustness of the results. CONCLUSIONS After controlling for confounding variables, the strategy of early surgery for hip fracture in the older adults was proven to be dominant, because it presented a lower cost and better results than late surgery.

    This manuscript discusses the current surgical management of glioblastoma. This paper highlights the common pathophysiology attributes of glioblastoma, surgical options for diagnosis/treatment, current thoughts of extent of resection (EOR) of tumor, and post-operative (neo)adjuvant treatment. Glioblastoma is not a disease that can be cured with surgery alone, however safely performed maximal surgical resection is shown to significantly increase progression free and overall survival while maximizing quality of life. Upon invariable tumor recurrence, re-resection also is shown to impact survival in a select group of patients. As adjuvant therapy continues to improve survival, the role of surgical resection in the treatment of glioblastoma looks to be further defined. PMID:26207249

    A total of 473 strains of Enterobacteriaceae, including Escherichia coli, Klebsiella spp., Proteus spp., Citrobacter spp., Enterobacter spp., Serratia spp. and Providencia spp., were isolated from patients admitted to intensive care units and surgical units in Russia. About 90% of the isolates carried factors resistant to beta-lactams. The isolation rates of the extended-spectrum beta-lactamase (ESBL) producer defined in this study among E. coli, Klebsiella spp. and Proteus spp. were 45%, 48% and 17%, respectively. In the settings with high prevalence of the ESBL producer, flomoxef, which belongs to the oxacephem subgroup, and carbapenems retain their activity. The MIC₅₀ of flomoxef, meropenem and imipenem against total isolates were 1 µg/mL, ≤ 0.063 µg/mL and 0.25 µg/mL, respectively. Fifty-five carbapenem-resistant strains were isolated in this study. The carbapenem resistant rates of E. coli, Klebsiella spp. and Proteus spp. were 3%, 16% and 29%, respectively

    Combination of ruptured sinus of Valsalva aneurysm (SVA), and a coexisting asymptomatic adult aortic isthmic coarctation is extremely rare. The timing and sequence of surgical and/or interventional repair of these two pathologies are controversial. We present a case of a 37-year-old male who was admitted to our department because of severe acute congestive heart failure and signs of ruptured aneurysm of the SV into the right ventricle. Transthoracic and transoesophageal echocardiography confirmed the communication between an important right coronary SVA and right ventricle, bicuspid aortic valve, mild aortic regurgitation, and revealed severe aortic coarctation. Because of the severe dilation of right sinus of Valsalva a surgical repair of the ruptured aneurysm was performed. Aortic coarctation was treated four weeks later by a percutaneous stent-graft implantation. This case report supports the concept that hybrid approach is feasible in patients with ruptured SVA and aortic coarctation in adulthood.

    This study investigated the associations between types and intensity of life events and symptoms of depression among adults with intellectual disabilities. A community sample (N = 593) was screened for current depression and exposure to life events (i.e., loss, illness, change, and bullying) during the previous 12 months. Symptoms of depression were measured using the Psychopathology Checklists for Adults With Intellectual Disabilities. Exposure to three of the four types of life events studied (loss, illness, and bullying) and the intensity of the events were associated with depression, particularly in the cases of loss of relatives and bullying. Quality of care moderated the association between bullying and depression and may buffer the adverse consequences of bullying. PMID:27611352

    Volunteer service opportunities for older adults may soon be expanded. Although volunteering is thought to provide health benefits for healthier older adults, it is not known whether older adults in less than very good health are suitable candidates for high-intensity volunteering and can derive health benefits. This manuscript presents a prospective analysis of 174 older adult volunteers serving in Experience Corps Baltimore, a high-intensity senior volunteer program in Baltimore, Maryland. Volunteers served > or =15 h per week, for a full school year, in elementary schools helping children with reading and other skills between 1999 and 2002. Volunteers were assessed with standardized questionnaires and performance-based testing including grip strength, walking speed, chair stand speed, and stair-climbing speed prior to school volunteering and at the end of the school year. Results were stratified by health status. Among 174 volunteers, 55% initially reported "good" and 12% "fair" or "poor" health status. At baseline, those in fair health reported higher frequencies of disease and disability than volunteers in excellent or very good health. After volunteering, a majority of volunteers in every baseline health status category described increased strength and energy. Those in fair health were significantly more likely to display improved stair-climbing speed than those in good or excellent/very good health (100.0% vs. 53.4% vs. 37.5%, p = 0.05), and many showed clinically significant increases in walking speed of >0.5 m/s. Satisfaction and retention rates were high for all health status groups. Clinicians should consider whether their patients in fair or good health, as well as those in better health, might benefit from high-intensity volunteer programs. Productive activity such as volunteering may be an effective community-based approach to health promotion for older adults.

    Background Sedentary aging leads to adverse changes in vascular function and cardiac performance. We published improvements in vascular function with moderate intensity physical activity (PA) in continuous bouts. Whether moderate intensity PA also impacts cardiac structure and cardiovascular performance of the aging left ventricle (LV) is unknown. Methods We recruited and analyzed results from 102 sedentary older adults ages ≥ 50 from a randomized controlled trial with 3 study groups: control (group 1), a pedometer-only intervention (group 2), or a pedometer with an interactive website employing strategies to increase habitual physical activity (PA, group 3) for 12 weeks. Transthoracic echocardiograms were performed prior to and following the 12 week intervention period to assess cardiac morphology, left ventricular (LV) systolic performance, LV diastolic function, arterial and LV ventricular elastance. Step count and PA intensity/distribution were measured by pedometer and accelerometer. Results We found no significant changes in cardiac morphology. Further, we found no improvement in the aforementioned cardiac functional parameters. Comparing those who achieved the following benchmarks to those who did not showed no significant changes in cardiac structure or performance: 1)10,000 steps/day, 2) ≥ 30 minutes/day of moderate intensity physical activity, or 3) moderate intensity PA in bouts ≥ 10 minutes for ≥ 20 minutes/day Conclusions In sedentary older adults, increasing moderate intensity PA to currently recommend levels does not result in favorable changes in LV morphology or performance over 12 weeks. More prolonged exposure, higher PA intensity, or earlier initiation of PA may be necessary to see benefits. PMID:25530947

    Hippocampal atrophy is associated with memory impairment and dementia and serves as a key biomarker in the preclinical stages of Alzheimer's disease. Physical activity, one of the most promising behavioral interventions to prevent or delay cognitive decline, has been shown to be associated with hippocampal volume; specifically increased aerobic activity and fitness may have a positive effect on the size of the hippocampus. The majority of older adults, however, are sedentary and have difficulty initiating and maintaining exercise programs. A modestly more active lifestyle may nonetheless be beneficial. This study explored whether greater objectively measured daily walking activity was associated with larger hippocampal volume. We additionally explored whether greater low-intensity walking activity, which may be related to leisure-time physical, functional, and social activities, was associated with larger hippocampal volume independent of exercise and higher-intensity walking activity. Segmentation of hippocampal volumes was performed using Functional Magnetic Resonance Imaging of the Brain's Software Library (FSL), and daily walking activity was assessed using a step activity monitor on 92, nondemented, older adult participants. After controlling for age, education, body mass index, cardiovascular disease risk factors, and the Mini Mental State Exam, we found that a greater amount, duration, and frequency of total daily walking activity were each associated with larger hippocampal volume among older women, but not among men. These relationships were specific to hippocampal volume, compared with the thalamus, used as a control brain region, and remained significant for low-intensity walking activity, independent of moderate- to vigorous-intensity activity and self-reported exercise. This is the first study, to our knowledge, to explore the relationship between objectively measured daily walking activity and hippocampal volume in an older adult population. Findings

    This study was designed to examine the psychological benefits of anaerobic exercise for older adults. Specifically, strength training was employed to examine the effects on mood and anxiety in a group of healthy but sedentary older women. 36 women (mean age = 68.5 yr.) were randomly assigned to groups given high intensity or moderate intensity strength training or to a control group. Strength training was conducted three days a week for 12 weeks. After the training period, both high and moderate strength-training programs produced marked improvements in muscle strength and body composition compared to the control subjects. The average improvements in the high and moderate intensity strength-training groups for muscle strength were 40.5 and 35.5%, respectively, and for percent body fat 1.52 and 2.50%, respectively. As for psychological changes, both training groups significantly improved positive mood (vigor), and the moderate intensity group significantly reduced trait anxiety compared to means of the control group. Also, both training groups showed some decrease in tension and state anxiety after the training period. These findings provide evidence for the effectiveness of anaerobic training to enhance perception of psychological well-being in older women. A moderate intensity rather than high intensity of training regimen may be more beneficial for sedentary older women to improve psychological health.

    Previous research has suggested that gardening activity could be an effective form of regular exercise for improving physical and psychological health in later life. However, there is a lack of data regarding the exercise intensities of various gardening tasks across different types of gardening and different populations. The purpose of this study was to examine the exercise intensity of gardening activity for older adult allotment gardeners in Wales, United Kingdom following a similar procedure used in previous studies conducted in the United States and South Korea by Park and colleagues (2008a; 2011). Oxygen consumption (VO2) and energy expenditure for six gardening tasks were measured via indirect calorimetery using the portable Oxycon mobile device. From these measures, estimated metabolic equivalent units (METs) were calculated. Consistent with Park et al. (2008a; 2011) the six gardening tasks were classified as low to moderate-high intensity physical activities based on their metabolic values (1.9-5.7 METs).

    Introduction Delayed union and non-union of displaced femoral neck fractures remains a difficult clinical problem for orthopaedic surgeons. In the physiologically young patient, every effort should be made to preserve the native hip joint. We present two cases of ununited femoral neck fractures in young adults who were successfully treated with low-intensity pulsed ultrasound (LIPUS) and showed satisfactory results. Presentation of case 1 A 41-year-old woman was involved in a motor vehicle crash and was diagnosed with displaced femoral neck fracture. Eleven months after internal fixation, a computed tomography (CT) scan revealed the presence of non-union of the femoral neck. LIPUS treatment was therefore initiated. After eight months, the fracture was completely consolidated. Presentation of case 2 A 39-year-old man was involved in a cycling accident and was diagnosed with displaced femoral neck fracture. Thirteen weeks after internal fixation, a CT scan revealed delayed union of the femoral neck. LIPUS treatment was therefore initiated. After six months, the fracture was completely consolidated. Conclusion We suggest use of LIPUS as a possible treatment approach for delayed union and non-union of displaced femoral neck fractures in young patients before considering further surgical intervention.

    The purpose of this study was to identify social cognitive theory (SCT) correlates of moderate- to vigorous-intensity exercise (MVPA) among adults with type 2 diabetes. Adults with type 2 diabetes (N = 181) participated in the study. Participants were recruited through ResearchMatch.org to complete an online survey. The survey used previously validated instruments to measure dimensions of self-efficacy, self-regulation, social support, outcome expectations, the physical environment, and minutes of MVPA per week. Spearman Rank Correlations were used to determine the relationship between SCT variables and MVPA. Classification and Regression Analysis using a decision tree model was used to determine the amount of variance in MVPA explained by SCT variables. Due to low levels of vigorous activity, only moderate-intensity exercise (MIE) was analyzed. SCT variables explained 42.4% of the variance in MIE. Self-monitoring, social support from family, social support from friends, and self-evaluative outcome expectations all contributed to the variability in MIE. Other contributing variables included self-reward, task self-efficacy, social outcome expectations, overcoming barriers, and self-efficacy for making time for exercise. SCT is a useful theory for identifying correlates of MIE among adults with type 2 diabetes. The SCT correlates can be used to refine diabetes education programs to target the adoption and maintenance of regular exercise.

  15. Intensive medical student involvement in short-term surgical trips provides safe and effective patient care: a case review

    PubMed Central

    2011-01-01

    Background The hierarchical nature of medical education has been thought necessary for the safe care of patients. In this setting, medical students in particular have limited opportunities for experiential learning. We report on a student-faculty collaboration that has successfully operated an annual, short-term surgical intervention in Haiti for the last three years. Medical students were responsible for logistics and were overseen by faculty members for patient care. Substantial planning with local partners ensured that trip activities supplemented existing surgical services. A case review was performed hypothesizing that such trips could provide effective surgical care while also providing a suitable educational experience. Findings Over three week-long trips, 64 cases were performed without any reported complications, and no immediate perioperative morbidity or mortality. A plurality of cases were complex urological procedures that required surgical skills that were locally unavailable (43%). Surgical productivity was twice that of comparable peer institutions in the region. Student roles in patient care were greatly expanded in comparison to those at U.S. academic medical centers and appropriate supervision was maintained. Discussion This demonstration project suggests that a properly designed surgical trip model can effectively balance the surgical needs of the community with an opportunity to expose young trainees to a clinical and cross-cultural experience rarely provided at this early stage of medical education. Few formalized programs currently exist although the experience above suggests the rewarding potential for broad-based adoption. PMID:21884604

    This study investigated the ability of adults with Asperger syndrome to recognize emotional categories of facial expressions and emotional prosodies with graded emotional intensities. The individuals with Asperger syndrome showed poorer recognition performance for angry and sad expressions from both facial and vocal information. The group difference in facial expression recognition was prominent for stimuli with low or intermediate emotional intensities. In contrast to this, the individuals with Asperger syndrome exhibited lower recognition accuracy than typically-developed controls mainly for emotional prosody with high emotional intensity. In facial expression recognition, Asperger and control groups showed an inversion effect for all categories. The magnitude of this effect was less in the Asperger group for angry and sad expressions, presumably attributable to reduced recruitment of the configural mode of face processing. The individuals with Asperger syndrome outperformed the control participants in recognizing inverted sad expressions, indicating enhanced processing of local facial information representing sad emotion. These results suggest that the adults with Asperger syndrome rely on modality-specific strategies in emotion recognition from facial expression and prosodic information.

    This study examined the structure, concurrent validity, and reliability of a hassle measure for middle-aged adults in both event frequency and intensity recordings. The measure included a range of interpersonal day-to-day events and re-examined aspects of the primary appraisal confounding debate between Lazarus and colleagues (Lazarus, Delongis, Folkman, & Gruen, 1985) and Dohrenwend and Shrout (1985). Of the 373 participants, 73% were female, 72% were in paid work, 69% were in permanent relationships and 62% had children. Principal component analyses of separate hassle frequency and intensity scores highlighted components consistent with previous research. There were seven interpersonal and four non-interpersonal subscales associated with negative events with family and friends, work, health, money, and household. The subscales had very good reliability and concurrent validity and there were generally strong correlations (i.e. up .84) between frequency and intensity scores for each subscale. Given some important sampling limitations (e.g. female overrepresentation) the findings show a psychometrically sound hassle scale for adults. PMID:17999222

    Inherited hemophagocytic lymphohistiocytosis (HLH) is a genetic anomaly disorder in which abnormally activated cytotoxic T lymphocytes cannot induce the apoptosis of target cells and antigen-presenting cells, leading to hemophagocytosis, pancytopenia, and a variety of symptoms such as a high fever. The present patient with adult-onset HLH developed refractory disease despite receiving immunosuppressive treatments. He underwent a reduced-intensity conditioning (RIC) regimen that comprised antithymocyte globulin (ATG) followed by cord blood transplantation (RIC-CBT). He achieved and maintained a complete donor type. The incorporation of ATG into RIC-CBT may prevent graft failure and control hemophagocytosis, however, further efforts are necessary to reduce infectious complications. PMID:26984088

    PubMed

    2011-09-01

    In the intensive care environment, technology is omnipresent to ensure the monitoring and the administration of critical drugs to unstable patients. Since the early 2000's computerized physician order entry (CPOE), bar code assisted medication administration (BCMA), "smart" infusion pumps (SIP), electronic medication administration record (eMAR) and automated dispensing systems (ADS) have been recommended to reduce medication errors. About ten years later, their implementation rises but remains modest. The objective of this study is to determine the impact of these technologies on the rate of medication errors (ME) in adult intensive care. CPOE allows a strong and significant reduction of ME, especially the least critical ones. Only when adding a clinical decision support system (CDSS), CPOE could allow a reduction of serious errors. Used alone, it could even increase them. The available studies do not have the sufficient power to demonstrate the benefits of SIP or BCMA on ME. However, these devices, reveal practices, such as overriding of alerts. Power or methodology problems and conflicting results do not allow to determine the ability of ADS to reduce the incidence of ME in the intensive care. The studies, investigating these technologies, are not very recent, of limited number and present lacks in their methodology, which does not allow to determine whether they can reduce the incidence of MEs in the adult intensive care. Currently, the benefits appear to be limited which may be explained by the complexity of their integration into the care process. Special attention should be given to the communication between caregivers, the human-computer interface and the caregivers' training.

    According to psychological models as well as common intuition, intense positive and negative situations evoke highly distinct emotional expressions. Nevertheless, recent work has shown that when judging isolated faces, the affective valence of winning and losing professional tennis players is hard to differentiate. However, expressions produced by professional athletes during publicly broadcasted sports events may be strategically controlled. To shed light on this matter we examined if ordinary people's spontaneous facial expressions evoked during highly intense situations are diagnostic for the situational valence. In Experiment 1 we compared reactions with highly intense positive situations (surprise soldier reunions) versus highly intense negative situations (terror attacks). In Experiment 2, we turned to children and compared facial reactions with highly positive situations (e.g., a child receiving a surprise trip to Disneyland) versus highly negative situations (e.g., a child discovering her parents ate up all her Halloween candy). The results demonstrate that facial expressions of both adults and children are often not diagnostic for the valence of the situation. These findings demonstrate the ambiguity of extreme facial expressions and highlight the importance of context in everyday emotion perception. (PsycINFO Database Record

    Background. High-grade gliomas of the brainstem are rare in adults and are particularly rare in the anterolateral medulla. We describe an illustrative case and discuss the diagnostic and treatment issues associated with a tumor in this location, including differential diagnosis, anatomical considerations for options for surgical management, multimodality treatment, and prognosis. Case Description. A 69-year-old woman presented with a 3-week history of progressive right lower extremity weakness. She underwent an open biopsy via a far lateral approach with partial condylectomy, which revealed a glioblastoma. Concurrent temozolomide and radiation were completed; however, she elected to stop her chemotherapy after 5.5 weeks of treatment. She succumbed to her disease 11 months after diagnosis. Conclusions. Biopsy can be performed relatively safely to provide definitive diagnosis to guide treatment, but long-term prognosis is poor. PMID:27242937

    Introduction The World Health Organization has solicited rapid and minimally invasive techniques to facilitate scale-up of voluntary medical male circumcision (VMMC). Study design Non-blinded randomized controlled field trial with 2:1 allocation ratio. Participants 75 adult male volunteers. Setting Outpatient primary care clinic. Intervention Open surgical circumcision under local anesthetic with suturing vs. Unicirc disposable instrument under topical anesthetic and wound sealing with cyanoacrylate tissue adhesive. Primary Outcome Intraoperative duration. Secondary Outcomes Intraoperative and postoperative pain; adverse events; time to healing; patient satisfaction; cosmetic result. Results The intraoperative time was less with the Unicirc technique (median 12 vs. 25 min, p < 0.001). Wound healing and cosmetic results were superior in the Unicirc group. Adverse events were similar in both groups. Conclusions VMMC with Unicirc under topical anesthetic and wound sealing with cyanoacrylate tissue adhesive is rapid, heals by primary intention with superior cosmetic results, and is potentially safer and more cost-effective than open surgical VMMC.

    Background: A single bout of exercise improves postprandial glycemia and insulin sensitivity in prediabetic patients; however, the impact of exercise intensity is not well understood. The present study compared the effects of acute isocaloric moderate (MIE) and high-intensity (HIE) exercise on glucose disposal and insulin sensitivity in prediabetic adults. Methods: Subjects (n = 18; age 49 ± 14 y; fasting glucose 105 ± 11 mg/dL; 2 h glucose 170 ± 32 mg/dL) completed a peak O2 consumption/lactate threshold (LT) protocol plus three randomly assigned conditions: 1) control, 1 hour of seated rest, 2) MIE (at LT), and 3) HIE (75% of difference between LT and peak O2 consumption). One hour after exercise, subjects received an oral glucose tolerance test (OGTT). Plasma glucose, insulin, and C-peptide concentrations were sampled at 5- to 10-minute intervals at baseline, during exercise, after exercise, and for 3 hours after glucose ingestion. Total, early-phase, and late-phase area under the glucose and insulin response curves were compared between conditions. Indices of insulin sensitivity (SI) were derived from OGTT data using the oral minimal model. Results: Compared with control, SI improved by 51% (P = .02) and 85% (P < .001) on the MIE and HIE days, respectively. No differences in SI were observed between the exercise conditions (P = .62). Improvements in SI corresponded to significant reductions in the glucose, insulin, and C-peptide area under the curve values during the late phase of the OGTT after HIE (P < .05), with only a trend for reductions after MIE. Conclusion: These results suggest that in prediabetic adults, acute exercise has an immediate and intensity-dependent effect on improving postprandial glycemia and insulin sensitivity. PMID:24243632

    Background This paper intends to clarify clinical and anatomical features as well as pathological conditions of surgically treated adult patients with occipitalization of the atlas. Methods The authors reviewed 12 consecutive adult patients with occipitalization of the atlas who underwent surgery for myleopathy in our hospital. Mainly using preoperative computed tomography and three-dimensional computed tomography angiography, we investigated their anomalies of the osseous structures and vertebral artery at the cervical spine including the craniovertebral junction (CVJ). We also developed a new classification system for occipitalization of the atlas. Results Atlantoaxial subluxation (AAS) was detected in 9 patients (75%). The condition of AAS was irreducible in 7 patients. Among these 7 patients, deformity at the lateral atlantoaxial joints was detected in 2 patients. C2-3 fusion was detected in 6 patients (67%) among 9 patients with AAS. Anomalies of the VA were detected in 11 patients (92%). Occipitalization of the atlas was classified into three types according to their pathological conditions. In type 1 (2 patients) the medial atlantoaxial joint is semi-dislocated and the lateral atlantoaxial joints are severely deformed. Type 2 (7 patients) exhibits AAS but the lateral atlantoaxial joints are not deformed. Type 3 (3 patients) is not associated with AAS and therefore does not exhibit osseous stenosis at the CVJ. In type 3 the myelopathy was caused by another coexisting condition. Conclusions Occipitalization of the atlas is classified into three types. The main pathological condition in both types 1 and 2 is AAS. Reduction of AAS is essential in both; however, reduction of AAS in type 1 is more technically demanding than in type 2. The pathological conditions of type 3 are completely different from those of the others, so an accurate diagnosis must be made. The new classification system is a useful guide for surgeons when planning surgical strategies. PMID

    2016-05-01

    Developmental dysplasia of the hip (DDH) is a spectrum of disorders that results in anatomic abnormalities leading to increased contact stress in the joint and, eventually, secondary osteoarthritis. However, many patients with DDH become symptomatic before the severe degenerative changes of the hip because of abnormal hip biomechanics, mild hip instability, impingement, or associated intra-articular pathology. Early diagnosis and appropriate treatment for DDH are of the utmost importance. With the modification of techniques like pelvic osteotomy and capsular arthroplasty, and the introduction of intracapsular procedures such as arthroscopy and femoral head-neck junction osteochondroplasty, many young patients with symptomatic hip dysplasia may benefit from joint preservation procedures. We review the current development of these concepts and the associated surgical techniques. PMID:26216530

    Low-intensity physical activity is increasingly promoted as an alternative to sedentary behavior. However, much research to date has focused on moderate- to vigorous-intensity physical activity, and in particular dynamic work, with the effect of low-intensity isometric exercise (<4 METs) on substrate utilization yet to be explored. Here we investigate the effects of such exercise on respiratory quotient (RQ) and determine the extent of intra- and inter-individual variability in response. Energy expenditure, RQ, and substrate oxidation were measured by ventilated-hood indirect calorimetry at rest and in response to standardized, intermittent, low-level isometric leg-press exercises at 5 loads (+5, +10, +15, +20, +25 kg) in 26 healthy, young adults. Nine participants repeated the experiment on 3 separate days to assess within-subject, between-day variability. There was no significant difference in energy cost and heart rate responses to low-intensity isometric exercise (<2 METs) between men and women. However, a sex difference was apparent in terms of substrate oxidation - with men increasing both fat and carbohydrate oxidation, and women only increasing fat oxidation while maintaining carbohydrate oxidation at baseline, resting levels. This sex difference was repeatable and persisted when substrate oxidation was adjusted for differences in body weight or body composition. Individual variability in RQ was relatively low, with both intra- and inter-individual coefficients of variation in the range of 3%-6% in both sexes. These results suggest that women preferentially increase fat oxidation during low-level isometric exercise. Whether such physical activity could be incorporated into treatment/prevention strategies aimed at optimizing fat oxidation in women warrants further investigation.

    Background: Intradural spinal cord tumors (IDSCTs) in children and young adults are rare diseases. This present study is aimed to demonstrate our experience with a large series of children and young adults with IDSCT. Methods: A total of 50 patients aged <20 years with IDSCT treated in our department between 1990 and 2010 were included in the study. Clinical, histological, and radiological findings, treatment strategies, and clinical outcome were retrospectively assessed. Depending on the relation to the spinal cord, IDSCT were dichotomized into intramedullary SCT (IMSCT) and extramedullary SCT (EMSCT). The functional outcome was evaluated with the Frankel score assessing the longest available follow-up period. Results: Mean age was 10.3 years (range 6 months–19 years). IDSCT surgery was performed in 44 patients (88%). A common first symptom in patients with EMSCT was neck and back pain (41%), whereas monoparesis of arms (43%) were often seen in patients with IMSCT. The main duration of the symptoms was longer in patients with IMSCT. The postoperative functional outcome was generally comparable to the preoperative functional condition, while better for EMSCT (P < 0.01). The functional outcome at last follow-up correlated significantly with the preoperative Frankel score (P < 0.002). Conclusion: Due to the mostly mild impact of the surgery on the functional outcome, the surgical treatment of IDSCT in children and young patients can be uniquely advocated. PMID:26713174

    2015-01-01

    Background. Physical activity guidelines for adults only recognize the health benefits of accumulating bouted moderate-to-vigorous physical activity (MVPA), or MVPA occurring over at least 10 consecutive minutes. There is a lack of evidence supporting the health benefits of other patterns and intensities of activity including sporadic MVPA (i.e., MVPA occurring in periods of fewer than 10 consecutive minutes) and light intensity physical activity (LIPA). The objective of this study was to examine the health benefits associated with physical activity that does not meet the physical activity guidelines criteria for bouted MVPA. Specifically, we examined the association between sporadic MVPA and bouted and sporadic LIPA with the metabolic syndrome. Methods. We studied a representative cross-sectional sample of 1,974 adults aged 20 years and older from the 2003–2006 US National Health and Nutrition Examination Survey. Physical activity was measured over 7 days using Actigraph AM-7164 accelerometers. Each minute over the 7-day measurement period was classified as being of a sedentary, light, or moderate-to-vigorous intensity. A 10 min threshold differentiated bouted activity from sporadic activity. Average minutes/day of sporadic LIPA, sporadic MVPA, bouted LIPA, bouted MVPA, and embedded MVPA (MVPA occurring within bouts of primarily LIPA) were calculated. Metabolic syndrome status was determined using established criteria. Associations were examined using logistic regression and controlled for relevant covariates. Results. For every 30 min/day of physical activity, the odds ratio (95% confidence interval) of the metabolic syndrome was reduced by 4% (1–7%) for bouted LIPA, 64% (51–71%) for bouted MVPA, and 57% (45–67%) for embedded MVPA. Sporadic LIPA was not independently associated with the metabolic syndrome. We could not examine the association between sporadic MVPA and the metabolic syndrome because participants accumulated such a marginal amount of this

    Culture and national care models matter both in reporting and treatment of pain status. However, most findings on body pain intensity and interference in adults are from Western studies, with little reliable evidence from China. This study aimed to assess body pain intensity and interference and its associations with demographic, socioeconomic characteristics, and health behaviors in adults. A cross-sectional survey was performed to collect data from 1224 adults, who were recruited via multistage stratified random sampling. The SF-36 quality-of-life instrument was used to investigate body pain intensity and interference. Ordinal logistic regression analysis was used in this study. Our results showed that 64.1% of the participants (males: 687; females: 537) reported body pain, and 45.7% of the participants reported body pain interference. Middle-aged respondents who were female, were unmarried/divorced or separated/widowed, had a negative relationship with their family, had poor sleep quality, and were not satisfied with their current living conditions had a higher body pain intensity rating (ordered logistic regression/six-level pain intensity criterion; odds ratios, p < 0.05). Respondents who were unmarried/divorced or separated/widowed, with a low education level, were unemployed, had lower incomes, had a negative relationship with their family, and were not satisfied with their current living conditions had a higher body pain interference rating (ordered logistic regression/five-level pain interference criterion; odds ratios, p < 0.05). In conclusion, an estimated 64.1% of middle-aged adults reported body pain, and 45.7% of middle-aged adults reported body pain interference. These results provide a clue for possible interventions for improving body pain intensity and interference in adults, especially among middle-aged people. These factors should be taken into consideration in the prevention of pain, pain management and treatment planning in order to help

Respondents who were unmarried/divorced or separated/widowed, with a low education level, were unemployed, had lower incomes, had a negative relationship with their family, and were not satisfied with their current living conditions had a higher body pain interference rating (ordered logistic regression/five-level pain interference criterion; odds ratios, p < 0.05). In conclusion, an estimated 64.1% of middle-aged adults reported body pain, and 45.7% of middle-aged adults reported body pain interference. These results provide a clue for possible interventions for improving body pain intensity and interference in adults, especially among middle-aged people. These factors should be taken into consideration in the prevention of pain, pain management and treatment planning in order to help

    Radio-tagged adult Pacific lamprey Entosphenus tridentatus held in a raceway with Plexiglas-lined walls and bottom healed more slowly and retained sutures longer than fish held in an all-concrete raceway or one with Plexiglas walls and a cobble-lined bottom. On all substrata, healing depended on when sutures were lost, and fish that lost their sutures in <14 days post-surgery healed faster than those that kept sutures longer. Long-term suture retention led to tissue trauma, infection and poor survival.

    Adult patients presenting with an overcorrected clubfoot often have had a posteromedial release. They present later in life and have compensated quite well despite the development of deformity. Minor trauma may lead to the onset of acute symptoms. A spectrum of deformity exists. Key features include a dorsally subluxated navicular, a dorsal bunion from overpull of the tibialis anterior tendon, valgus of the ankle or hindfoot or both, and a flattop talus. This article details the diagnostic approach to the overcorrected clubfoot patient and options for management of the various components of the deformity. PMID:26589080

    Accessing timely acute medical care is a challenge for older adults. This article describes an innovative healthcare model that uses high-intensity telemedicine services to provide rapid acute care for older adults without requiring them to leave their senior living community (SLC) residences. This program, based in a primary care geriatrics practice that cares for SLC residents, is designed to offer acute care through telemedicine for complaints that are felt to need attention before the next available outpatient visit but not to require emergency department (ED) resources. This option gives residents access to care in their residence. Measures used to evaluate the program include successful completion of telemedicine visits, satisfaction of residents and caregivers with telemedicine care, and site of care that would have been recommended had telemedicine been unavailable. During the first 2 years of the program's operation, 281 of 301 requested telemedicine visits were completed successfully. Twelve residents were sent to an ED for care after the telemedicine visit. Ninety-four percent of residents reported being satisfied or very satisfied with telemedicine care. Had telemedicine not been available, residents would have been sent to an ED (48.1%) or urgent care center (27.0%) or been scheduled for an outpatient visit (24.4%). The project demonstrated that high-intensity telemedicine services for acute illnesses are feasible and acceptable and can provide definitive care without requiring ED or urgent care use. Continuation of the program will require evaluation demonstrating equal or better resident-level outcomes and the development of sustainable business models.

    Intestinal failure (IF) is a debilitating condition of inadequate nutrition due to an anatomical and/or physiological deficit of the intestine. Surgical management of patients with acute and chronic IF requires expertise to deal with technical challenges and make correct decisions. Dedicated IF units have expertise in patient selection, operative risk assessment and multidisciplinary support such as nutritional input and interventional radiology, which dramatically improve the morbidity and mortality of this complex condition and can beneficially affect the continuing dependence on parenteral nutritional support. Currently there is little guidance to bridge the gap between general surgeons and specialist IF surgeons. Fifteen European experts took part in a consensus process to develop guidance to support surgeons in the management of patients with IF. Based on a systematic literature review, statements were prepared for a modified Delphi process. The evidence for each statement was graded using Oxford Centre for Evidence-Based Medicine Levels of Evidence. The current paper contains the statements reflecting the position and practice of leading European experts in IF encompassing the general definition of IF surgery and organization of an IF unit, strategies to prevent IF, management of acute IF, management of wound, fistula and stoma, rehabilitation, intestinal and abdominal reconstruction, criteria for referral to a specialist unit and intestinal transplantation.

    A posttraumatic open bite associated with a bird face is reported. Condylectomy was indicated in relation to the plurifragmentary fracture of the condyles with limitation of mandibular movement. Condylectomies were mandatory as a result of delayed maxillofacial surgical treatment, which was related to the poor general condition of the patient after trauma. Functional disorder recovery and aesthetic deformity correction were planned by a team approach between orthodontists and maxillofacial surgeons with the support of a logopedist for the postural-related muscle problems. The main practical and theoretical problems presented by the clinical case were a result of the need to restore the occlusal relations and to avoid recurrence of open bite in this patient. The patient presented a wide alteration of muscular function and a strength fibrotic retraction with alteration in the relationship between upper and lower jaws and retrusion of the mandible associated to open bite. Orthodontic treatment was carried with no impact on the upper and lower axis, avoiding orthodontic correction of the open bite. Surgery corrected both the open bite and the bird face by means of bilateral sagittal split osteotomies. Wiring of the mandibular osteotomies and intermaxillary fixation allowed positioning of the mandibular ramus bilaterally because of the fibrosis and muscular action-related forces without resulting in a similar rotation of the mandible with the risk of recurrence. Myotherapy and logopedic support minimized the risk of recurrence, improved reduction of muscular tension with the resolution of the lip incompetence, and allowed functional recovery of mandibular movements.

    Objective. The purpose of this study was to assess the effect of high intensity interval training (HIIT) versus continuous aerobic exercise training (CONT) or placebo (PLA) on body composition by randomized controlled design. Methods. Work capacity and body composition (dual-energy X-ray absorptiometry) were measured before and after 12 weeks of intervention in 38 previously inactive overweight adults. Results. There was a significant group × time interaction for change in work capacity (P < 0.001), which increased significantly in CONT (23.8 ± 3.0%) and HIIT (22.3 ± 3.5%) but not PLA (3.1 ± 5.0%). There was a near-significant main effect for percentage trunk fat, with trunk fat reducing in CONT by 3.1 ± 1.6% and in PLA by 1.1 ± 0.4%, but not in HIIT (increase of 0.7 ± 1.0%) (P = 0.07). There was a significant reduction in android fat percentage in CONT (2.7 ± 1.3%) and PLA (1.4 ± 0.8%) but not HIIT (increase of 0.8 ± 0.7%) (P = 0.04). Conclusion. These data suggest that HIIT may be advocated as a time-efficient strategy for eliciting comparable fitness benefits to traditional continuous exercise in inactive, overweight adults. However, in this population HIIT does not confer the same benefit to body fat levels as continuous exercise training. PMID:24669314

    Objectives This study sought to identify the physical and chemical incompatibilities among the drugs administered intravenously to patients admitted to an adult intensive care unit. We also aimed to establish pharmaceutical guidelines for administering incompatible drugs. Methods This cross-sectional, prospective, and quantitative study was conducted from July to September 2015. Drug incompatibilities were identified based on an analysis of the patient prescriptions available in the hospital online management system. A pharmaceutical intervention was performed using the guidelines on the preparation and administration of incompatible drugs. Adherence to those guidelines was subsequently assessed among the nursing staff. Results A total of 100 prescriptions were analyzed; 68 were incompatible with the intravenous drugs prescribed. A total of 271 drug incompatibilities were found, averaging 4.0 ± 3.3 incompatibilities per prescription. The most commonly found drug incompatibilities were between midazolam and hydrocortisone (8.9%), between cefepime and midazolam (5.2%), and between hydrocortisone and vancomycin (5.2%). The drugs most commonly involved in incompatibilities were midazolam, hydrocortisone, and vancomycin. The most common incompatibilities occurred when a drug was administered via continuous infusion and another was administered intermittently (50%). Of the 68 prescriptions that led to pharmaceutical guidelines, 45 (66.2%) were fully adhered to by the nursing staff. Conclusion Patients under intensive care were subjected to a high rate of incompatibilities. Drug incompatibilities can be identified and eliminated by the pharmacist on the multidisciplinary team, thereby reducing undesirable effects among patients. PMID:27410410

    Background A defect of condylar morphology can be caused by several sources. Case report A case of altered condylar morphology in adult male with temporomandibular disorders was reported in 30-year-old male patient. Erosion and flattening of the left mandibular condyle were observed by panoramic x-ray. The patient was treated with splint therapy that determined mandibular advancement. Eight months after the therapy, reduction in joint pain and a greater opening of the mouth was observed, although crepitation sounds during mastication were still noticeable. Conclusion During the following months of gnatologic treatment, new bone growth in the left condyle was observed by radiograph, with further improvement of the symptoms. PMID:19619334

    Objective This study aimed to report our experiences with surgical repair in patients of all ages with persistent truncus arteriosus. Methods From July 2004 to July 2014, 50 consecutive patients with persistent truncus arteriosus who underwent anatomical repair were included in the retrospective review. Median follow-up time was 3.4 years (range, 3 months to 10 years). Results Fifty patients underwent anatomical repair at a median age of 19.6 months (range, 20 days to 19.1 years). Thirty patients (60%) were older than one year. The preoperative pulmonary vascular resistance and mean pulmonary artery pressure were 4.1±2.1 (range, 0.1 to 8.9) units.m2 and 64.3±17.9 (range, 38 to 101) mmHg, respectively. Significant truncal valve regurgitation was presented in 14 (28%) patients. Hospital death occurred in 3 patients, two due to pulmonary hypertensive crisis and the other due to pneumonia. Three late deaths occurred at 3, 4 and 11 months after surgery. The actuarial survival rates were 87.7% and 87.7% at 1 year and 5 years, respectively. Multivariate analysis identified significant preoperative truncal valve regurgitation was a risk factor for overall mortality (odds ratio, 7.584; 95%CI: 1.335–43.092; p = 0.022). Two patients required reoperation of truncal valve replacement. One patient underwent reintervention for conduit replacement. Freedom from reoperation at 5 years was 92.9%. At latest examination, there was one patient with moderate-to-severe truncal valve regurgitation and four with moderate. Three patients had residual pulmonary artery hypertension. All survivors were in New York Heart Association class I-II. Conclusions Complete repair of persistent truncus arteriosus can be achieved with a relatively low mortality and acceptable early- and mid-term results, even in cases with late presentation. Significant preoperative truncal valve regurgitation remains a risk factor for overall mortality. The long-term outcomes warrant further follow-up. PMID:26752522

    Piaget (1964) believed that interaction with the environment has a large part to play in human development. Matthew (1986) states that in an ideal world critically ill children should be cared for by staff trained in paediatrics, within designated paediatric intensive therapy units. Unfortunately, there are only 28 paediatric intensive therapy units in Great Britain (CMA Medical Data, 1987), consequently each year a third of children requiring intensive care are admitted to adult intensive therapy units (ITU). A knowledge and understanding of developmental psychology can therefore be beneficial to nurses in assessing which stage of development a child has reached, in order to plan the correct level of stimulation, and hence facilitate progress rather than regression in the accomplishment of developmental tasks. The psychological and social processes involved in Jean Piaget's (1896-1980) theory of human development are discussed with regard to nursing children requiring intubation and ventilation in an adult ITU.

    Background Del Nido (DN) cardioplegic solution (CPS) has been widely used during pediatric cardiac surgery. However, its use in the field of adult cardiac surgery is not popular yet. We evaluated efficacy of DN cardioplegia in adult cardiac surgical patients. Methods Fifty-three adult patients (mean age, 54±16 years) who underwent cardiovascular surgery using DN cardioplegia were enrolled. Myocardial troponin I (TnI) level up to three days after surgery and early clinical outcomes were evaluated. Propensity score matching was performed to compare these results with those after surgery using blood cardioplegia (BC). Results DN cardioplegia was infused with an initial dose of 1,126±221 mL, and an additional 500 mL was reinfused in 15 patients 91 minutes after initial infusion. After release of aortic cross clamp (ACC), spontaneous defibrillation was achieved in 94.3% (50/53). The peak TnI level after surgery was 9.8 ng/mL (range, 2.0–90.2 ng/mL). Linear regression models demonstrated that neither left ventricular mass (LVM) nor ACC time was associated with increased level of peak TnI (P=0.928 and 0.595, respectively). Early mortality occurred in one patient (1.9%). Postoperative complications included atrial fibrillation (n=18, 34.0%), acute kidney injury (n=4, 7.5%), low cardiac output syndrome (n=1, 1.9%), and respiratory complications (n=1, 1.9%). Propensity score matching extracted 39 pairs. Spontaneous defibrillation was achieved more frequently in the DN than BC groups (37/39 vs. 12/39, P<0.001). Peak level and serial changes of TnI were not statistically different between the two groups (P=0.085 and 0.959, respectively). There were also no significant differences in early mortality and postoperative complication rates between the two groups. Conclusions DN cardioplegia is as effective as BC for adult patients in terms of myocardial protection and early clinical outcomes.

    We conducted a quality improvement project in order to evaluate the effect of nurse-to-nurse bedside "rounding" as a strategy to decrease hospital-acquired pressure ulcers (HAPU) in a surgical intensive care unit. We instituted weekly peer-to-peer bedside skin rounds in a 17-bed surgical intensive care unit. Two nurses were identified as skin champions and trained by the hospital's certified WOC nurse to conduct skin rounds. The skin champion nurses conducted weekly peer-to-peer rounds that included discussions about key elements of our patients' skin status including current Braden Scale for Pressure Sore Risk score, and implementation of specific interventions related to subscale risk assessment. If a pressure ulcer was present, the current action plan was reevaluated for effectiveness. Quarterly HAPU prevalence studies were conducted from January 2008 to December 2010. Nineteen patients experienced a HAPU: 17 were located on the coccyx and 2 on the heel. Ten ulcers were classified as stage II, 3 PU were stage IV, 5 were deemed unstageable, and 1 was classified as a deep tissue injury. The frequency of preventive interventions rose during our quality improvement project. Specifically, the use of prevention surfaces increased 92%, repositioning increased 30%, nutrition interventions increased 77%, and moisture management increased 100%. Prior to focused nursing rounds, the highest HAPU prevalence rate was 27%. After implementing focused nursing rounds, HAPU rates trended down and were 0% for 3 consecutive quarters.

    Daily routine chest radiographs (CR) are commonly performed in surgical ICU. Unnecessary CR increase costs and expose the staff and the patients to radiation risk. The goal of our study was to estimate the value of daily routine CR in the ICU and to determine the correlation between CR and physical findings in surgical ICU patients. Prospective observational study was conducted during period of two months at the ICU department at the Clinic for Digestive Surgery, Clinical Center of Serbia, Belgrade. It included 97 consecutive patients who underwent digestive surgery and stayed at the ICU for at least two days. During their ICU stay, CRs were obtained as a clinical routine or to monitor lung pathology. Patients were followed daily, and CRs (as the proportion of positive findings) were compared with physical examination and clinical presentation. A total of 717 CRs were obtained, median number per patient was 4.0 (2.0-7.0). Proportion of positive findings was significantly higher comparing to auscultation until the sixth day of ICU stay. There was no difference in CR findings from day to day after the sixth day. Therapeutic efficacy of CRs was low as only 56 (7.8%) resulted in a change of patient management. We conclude that daily routine CRs are justified in the first six days of ICU stay, and after that time they show no advantages over clinical examination. PMID:24669579

    Invasive Candida infections represent a diagnostic and therapeutic challenge for clinicians particularly in the intensive care unit (ICU). Despite substantial advances in antifungal agents and treatment strategies, invasive candidiasis remains associated with a high mortality. Recent guideline recommendations on the management of invasive candidiasis by the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) from 2012, the German Speaking Mycological Society and the Paul Ehrlich Society for Chemotherapy (DMykG/PEG) from 2011 and the Infectious Diseases Society of America (IDSA) from 2009 provide valuable guidance for diagnostic procedures and treatment of these infections but need to be interpreted in the light of the individual situation of the patient and the local epidemiology of fungal pathogens. The following recommendations for management of candidemia are common to all three guidelines. Any positive blood culture for Candida indicates disseminated infection or deep organ infection and requires antifungal therapy. Treatment should be initiated as soon as possible. Removal or changing of central venous catheters or other foreign material in the bloodstream is recommended whenever possible. Ophthalmological examination for exclusion of endophthalmitis and follow-up blood cultures during therapy are also recommended. Duration of therapy should be 14 days after clearance of blood cultures and resolution of symptoms. Consideration of surgical options and a prolonged antifungal treatment (weeks to months) are required when there is organ involvement. During the last decade several new antifungal agents were introduced into clinical practice. These innovative drugs showed convincing efficacy and favorable safety in randomized clinical trials. Consequently, they were integrated in recent therapeutic guidelines, often replacing former standard drugs as first-line options. Echinocandins have emerged as the generally preferred primary treatment in

    Background: The transport of critically ill patients for procedures or tests outside the Intensive Care Unit (ICU) is potentially hazardous; hence, the transport process must be organized and efficient. Plenty of data is available on pre- and inter-hospital transport of patients; the data on intrahospital transport of patients are limited. We audited the complications and benefits of intrahospital transport of critically ill patients in our tertiary care center over 6 months. Materials and Methods: One hundred and twenty adult critically ill cancer patients transported from the ICU for either diagnostic or therapeutic procedure over 6 months were included. The data collected include the destination, the accompanying person, total time spent outside the ICU, and any adverse events and adverse change in vitals. Results: Among the 120 adult patients, 5 (4.1%) required endotracheal intubation, 5 (4.1%) required intercostal drain placement, and 20 (16.7%) required cardiopulmonary resuscitation (CPR). Dislodgement of central venous catheter occurred in 2 (1.6%) patients, drain came out in 3 (2.5%) patients, orogastric tube came out in 1 (0.8%) patient, 2 (1.6%) patients self-extubated, and in one patient, tracheostomy tube was dislodged. The adverse events were more in patients who spent more than 60 min outside the ICU, particularly requirement of CPR (18 [25%] vs. 2 [4.2%], ≤60 min vs. >60 min, respectively) with P < 0.05. Transport led to change in therapy in 32 (26.7%) patients. Conclusion: Transport in critically ill cancer patients is more hazardous and needs adequate pretransport preparations. Transport in spite being hazardous may lead to a beneficial change in therapy in a significant number of patients. PMID:27630455

    The aim of this clinical report is to describe the complex treatment of an adult Class III malocclusion patient who was disappointed with the outcome of a previous oral rehabilitation. Interdisciplinary treatment planning was performed with a primary indication for implant removal because of marginal bone loss and gingival recession, followed by orthodontic and surgical procedures to correct the esthetics and skeletal malocclusion. The comprehensive treatment approach included: (1) implant removal in the area of the central incisors; (2) combined orthodontic decompensation with mesial displacement and forced extrusion of the lateral incisors; (3) extraction of the lateral incisors and placement of new implants corresponding to the central incisors, which received provisional crowns; (4) orthognathic surgery for maxillary advancement to improve occlusal and facial relationships; and finally, (5) orthodontic refinement followed by definitive prosthetic rehabilitation of the maxillary central incisors and reshaping of the adjacent teeth. At the three-year follow-up, clinical and radiographic examinations showed successful replacement of the central incisors and improved skeletal and esthetic appearances. Moreover, a Class II molar relationship was obtained with an ideal overbite, overjet, and intercuspation. In conclusion, we report the successful esthetic anterior rehabilitation of a complex case in which interdisciplinary treatment planning improved facial harmony, provided gingival architecture with sufficient width and thickness, and improved smile esthetics, resulting in enhanced patient comfort and satisfaction. This clinical case report might be useful to improve facial esthetics and occlusion in patients with dentoalveolar and skeletal defects. PMID:26877982

    We analyzed the clinical and laboratory findings of both pediatric and adult patients with oropharyngeal tularemia. We also compared the therapeutic outcomes of patients who underwent surgical drainage of lymph nodes early or late during antibiotic therapy. A total of 68 patients with oropharyngeal tularemia, including 26 children and 42 adults, were enrolled in this study. The average duration between symptom onset and hospital admission was 20.8 days (4-60 days) in the pediatric group and 32.6 days (4-90 days) in the adult group (P = 0.009). The most frequently observed clinical symptoms were sore throat (100% and 100%), fever (96.2% and 90.5%), tonsillitis (69.2% and 78.6%), and rash (15.4% and 11.9%) in the pediatric and adult groups, respectively. However, the frequencies of erythema, tenderness, and fluctuant of enlarged lymph nodes were significantly higher in the adult group than in the pediatric group (P = 0.005, P = 0.029, and P = 0.041, respectively). Treatment failure was observed in 2 (7.7%) pediatric patients and 4 (9.5%) adult patients, for a total of 6 (8.8%) treatment failures in the study group. Similar clinical findings and treatment outcomes were observed in both groups. We concluded that a combination of surgical drainage and antibiotic therapy increases treatment success for patients diagnosed with oropharyngeal tularemia.

    Background Vietnam is a lower middle-income country with no national surveillance system for hospital-acquired infections (HAIs). We assessed the prevalence of hospital-acquired infections and antimicrobial use in adult intensive care units (ICUs) across Vietnam. Methods Monthly repeated point prevalence surveys were systematically conducted to assess HAI prevalence and antimicrobial use in 15 adult ICUs across Vietnam. Adults admitted to participating ICUs before 08:00 a.m. on the survey day were included. Results Among 3287 patients enrolled, the HAI prevalence was 29.5% (965/3266 patients, 21 missing). Pneumonia accounted for 79.4% (804/1012) of HAIs Most HAIs (84.5% [855/1012]) were acquired in the survey hospital with 42.5% (363/855) acquired prior to ICU admission and 57.5% (492/855) developed during ICU admission. In multivariate analysis, the strongest risk factors for HAI acquired in ICU were: intubation (OR 2.76), urinary catheter (OR 2.12), no involvement of a family member in patient care (OR 1.94), and surgery after admission (OR 1.66). 726 bacterial isolates were cultured from 622/1012 HAIs, most frequently Acinetobacter baumannii (177/726 [24.4%]), Pseudomonas aeruginosa (100/726 [13.8%]), and Klebsiella pneumoniae (84/726 [11.6%]), with carbapenem resistance rates of 89.2%, 55.7%, and 14.9% respectively. Antimicrobials were prescribed for 84.8% (2787/3287) patients, with 73.7% of patients receiving two or more. The most common antimicrobial groups were third generation cephalosporins, fluoroquinolones, and carbapenems (20.1%, 19.4%, and 14.1% of total antimicrobials, respectively). Conclusion A high prevalence of HAIs was observed, mainly caused by Gram-negative bacteria with high carbapenem resistance rates. This in combination with a high rate of antimicrobial use illustrates the urgent need to improve rational antimicrobial use and infection control efforts. PMID:26824228

    The Supports Intensity Scale-Adult Version is a standardized assessment of support needs. This study examined the factorial validity of the standardized portion of the scale, finding that the six-factor model (Home Living, Community Living, Lifelong Learning, Employment, Health and Safety, Social Activities) demonstrated good fit, and that the inclusion of the Protection and Advocacy Scale did not affect fit and contributed unique information. Age and gender impacted intensity of support needs, with those of transition age and in late adulthood having the highest intensities. Gender also impacted support needs, but in fewer instances. Implications for future research are discussed. PMID:26701074

  15. “The National Surgery Quality Improvement Project” (NSQIP): a new tool to increase patient safety and cost efficiency in a surgical intensive care unit

    2014-01-01

    Background The “National Surgical Quality Improvement Program” (NSQIP) is a nationally validated, risk-adjusted database tracking surgical outcomes. NSQIP has been demonstrated to decrease complications, expenses, and mortality. In the study institution, a high rate of nosocomial pneumonia (PNEU) and prolonged ventilator days ≥48 hours (V48) was observed on the surgical service. Methods The hospital studied is a 500 bed university-affiliated teaching hospital performing approximately 20,000 surgical operations per year. A multidisciplinary team was formed and a series of interventions were implemented to address high pneumonia rates and prolonged intubation. Specific interventions included enforcement of protocols and adherence to the Institute for Healthcare Improvement (IHI) ventilator bundles, including head of bed elevation, sedation holidays, extubate when ready, and early nutrition. NSQIP collected pre-operative through 30-day postoperative data prospectively on 1,081 surgical patients in the intensive care unit from January 1, 2010 – July 31, 2012. The variables pneumonia and V48 undergo logistic regression and risk adjusted results of observed versus expected are calculated. Mean and confidence intervals are represented in caterpillar charts and bar graphs. Statistical analysis was via Fisher exact t-test. Results Progressive improvements were observed over a two-year period via three semiannual reports (SAR). Corrective measures showed a decrease in V48 with an observed to expected odds ratio (O: E) improving from 1.5 to 1.04, or 1.9% ( 7/368 patients) July 31, 2011 to 1.11% (12/1080 patients) July 31, 2012 respectively. Similarly, pneumonia rates decreased 1.36% (5/368 patients) July 31, 2011 to 1.2% ( 13/1081 patients) July 31, 2012 with O: E = 1.4 and 1.25 respectively. Statistical significance was achieved (p < .05). Conclusion Given an estimated annual volume of 20,000 cases per year with a cost of $22,097 per episode of pneumonia and

    Using three spatial network measures of “space syntax”, this correlational study describes four interaction-related behaviors among three groups of users in relation to visibility and accessibility of spaces in four adult intensive care units (ICUs) of different size, geometry, and specialty. Systematic field observations of interaction-related behaviors show significant differences in spatial distribution of interaction-related behaviors in the ICUs. Despite differences in unit characteristics and interaction-related behaviors, the study finds that when nurses and physicians “interact while sitting” they prefer spaces that help maintain a high level of environmental awareness; that when nurses “walk” and “interact while walking” they avoid spaces with better global access and visibility; and that everyone in ICUs “walk” more in spaces with higher control over neighboring spaces. It is argued that such consistent behavioral patterns occur due to the structural similarities of spatial networks over and above the more general functional similarities of ICUs. PMID:25469838

    Cannabinoids purportedly improve taste responsiveness and enhance the sensory appeal of foods. These properties and a commonly cited oral drying effect were evaluated in a series of studies with 'light' marijuana users. The first was a double-blind, placebo-controlled, acute oral dosing trial, involving an age and gender stratified sample of 57 adults. An influence of route of drug delivery was explored in another 11 individuals who were administered a single dose orally, sublingually and via cigarette. To explore effects following chronic administration, six additional individuals were dosed twice per day for 3 days orally and by rectal suppository. Taste intensity and hedonic responses for sweet, sour, salty and bitter food stimuli were monitored at baseline, 2, 4 and 6 hours post-dosing in the acute studies, and daily in the chronic study. Stimulated saliva samples were collected at these same times. Salivary flow rate was significantly negatively correlated with plasma drug levels, and reported 'high' 2 and 4 h post-dosing. No effects of the drug were observed on taste responses. Self-reported shifts in taste responsiveness and hedonics may be related to alterations of memory and cognition, rather than gustatory function. PMID:8055263

    Acute care of children remains a challenge due to a shortage of pediatric surgeons, particularly in rural areas. In our institutional norm, all cases in patients age six and older are managed by dedicated general surgeons. The provision of care to these children by these surgeons alleviates the impact of such shortages. We conducted a five-year retrospective analysis of all acute care pediatric surgical cases performed in patients aged 6 to 17 years by a dedicated group of adult general surgeons in a rural tertiary care hospital. Demographics, procedure, complications, outcomes, length of stay, and time of consultation/operation were obtained via chart review. Elective, trauma related, or procedures performed by a pediatric surgeon were excluded. Descriptive statistics are reported. A total of 397 cases were performed by six dedicated general surgeons during the study period. Mean age was 11.5 ± 3.1 years. In all, 100 (25.2%) were transferred from outlying facilities and 52.6 per cent of consultations/operations occurred at night (7P-7A), of which 33.2 per cent occurred during late night hours (11P-7A). On weekends, 34.0 per cent occurred. Appendectomy was the most commonly performed operation (n = 357,89.9%), of which 311 were laparoscopic (87.1%). Others included incision/drainage (4.5%), laparoscopic cholecystectomy (2.0%), bowel resection (1.5%), incarcerated hernia (0.5%), small bowel obstruction (0.5%), intra-abdominal abscess drainage (0.3%), resection of intussusception (0.3%), Graham patch (0.3%), and resection omental torsion (0.3%). Median length of stay was two days. Complications occurred in 23 patients (5.8%), of which 22(5.5%) were the result of the disease process. These results parallel those published by pediatric surgeons in this age group and for the diagnoses treated.

    Aims. High-intensity interval training (HIIT) leads to improvements in various markers of cardiometabolic health but adherence to HIIT following a supervised laboratory intervention has yet to be tested. We compared self-report and objective measures of physical activity after one month of independent exercise in individuals with prediabetes who were randomized to HIIT (n = 15) or traditional moderate-intensity continuous training (MICT, n = 17). Method. After completing 10 sessions of supervised training participants were asked to perform HIIT or MICT three times per week for four weeks. Results. Individuals in HIIT (89 ± 11%) adhered to their prescribed protocol to a greater extent than individuals in MICT (71 ± 31%) as determined by training logs completed over one-month follow-up (P = 0.05, Cohen's d = 0.75). Minutes spent in vigorous physical activity per week measured by accelerometer were higher in HIIT (24 ± 18) as compared to MICT (11 ± 10) at one-month follow-up (P = 0.049, Cohen's d = 0.92). Cardiorespiratory fitness and systolic blood pressure assessed at one-month follow-up were equally improved (P's < 0.05). Conclusions. This study provides preliminary evidence that individuals with prediabetes can adhere to HIIT over the short-term and do so at a level that is greater than MICT. PMID:25918728

    A randomized, double-blind, placebo-controlled trial of selective decontamination of the oropharynx and gastrointestinal tract was conducted on 61 intubated patients in a medical-surgical intensive care unit (ICU) to determine the impact on nosocomial pneumonia, other infections, and emergence of colonization or infection with antibiotic-resistant bacteria. Over 8 months, 30 patients received an oral paste and solution containing polymyxin, gentamicin, and nystatin; 31 patients received a placebo paste and solution. At study entry, patients in both groups were seriously ill (mean acute physiologic score, 27.2), frequently had pulmonary infiltrates (73.8%), and were likely to be receiving systemic antibiotics (86.9%). There were no differences between study patients and control patients in these characteristics or in frequency of any nosocomial infection (50% vs. 55%), nosocomial pneumonia (27% vs. 26%), febrile days (2.3 vs. 2.0), duration of antibiotic therapy (14.0 vs. 13.4), or mortality rates (37% vs. 48%). There was no difference in infections caused by antibiotic-resistant gram-negative bacilli, although a trend towards more frequent infection with gentamicin-resistant enterococci was found for study patients. Selective decontamination did not appear to be effective in our very ill medical-surgical ICU patients, although the number of patients in our trial was sufficient to detect only a 50% or greater reduction in pneumonia rates.

  2. Lower survival probabilities for adult Florida manatees in years with intense coastal storms

    The endangered Florida manatee (Trichechus manatus latirostris) inhabits the subtropical waters of the southeastern United States, where hurricanes are a regular occurrence. Using mark-resighting statistical models, we analyzed 19 years of photo-identification data and detected significant annual variation in adult survival for a subpopulation in northwest Florida where human impact is low. That variation coincided with years when intense hurricanes (Category 3 or greater on the Saffir-Simpson Hurricane Scale) and a major winter storm occurred in the northern Gulf of Mexico. Mean survival probability during years with no or low intensity storms was 0.972 (approximate 95% confidence interval = 0.961-0.980) but dropped to 0.936 (0.864-0.971) in 1985 with Hurricanes Elena, Kate, and Juan; to 0.909 (0.837-0.951) in 1993 with the March "Storm of the Century"; and to 0.817 (0.735-0.878) in 1995 with Hurricanes Opal, Erin, and Allison. These drops in survival probability were not catastrophic in magnitude and were detected because of the use of state-of-the-art statistical techniques and the quality of the data. Because individuals of this small population range extensively along the north Gulf coast of Florida, it was possible to resolve storm effects on a regional scale rather than the site-specific local scale common to studies of more sedentary species. This is the first empirical evidence in support of storm effects on manatee survival and suggests a cause-effect relationship. The decreases in survival could be due to direct mortality, indirect mortality, and/or emigration from the region as a consequence of storms. Future impacts to the population by a single catastrophic hurricane, or series of smaller hurricanes, could increase the probability of extinction. With the advent in 1995 of a new 25- to 50-yr cycle of greater hurricane activity, and longer term change possible with global climate change, it becomes all the more important to reduce mortality and injury

    Background: GlideScope (GS) is a video laryngoscope that allows a real-time view of the glottis and endotracheal intubation. It provides a better view of the larynx without the need for alignment of the airway axes. Aim: This prospective randomized comparative study is designed to compare the intubation time, hemodynamic response, and complications associated with intubation using a GS or Macintosh laryngoscope (ML) in adult subjects undergoing elective surgical procedures. Materials and Methods: Sixty American Society of Anesthesiologists physical status 1–2 patients were included in this prospective randomized comparative study. Patients were randomized to be intubated using either a GS or an ML. The primary outcome measure was the intubation time. The secondary outcome measures were the hemodynamic response to intubation and the incidence of mucosal injury. Statistical Analysis: Mean and standard deviation were calculated for different parameters under the study. The observed results were analyzed using Student's t-test for quantitative data and Z-test of proportions. P<0.05 was considered statistically significant. Results: Intubation time was longer in GS group (45.7033 ± 11.649 s) as compared to ML (27.773 ± 5.122 s) P< 0.0001 with 95% confidence interval (95% CI) −13.2794 to −22.5806. GS provided better Cormack and Lehane laryngoscopic view (P = 0.0016 for grade 1 view) with 95% CI −0.1389 to −0.5951. GS group exhibited more laryngoscopic response than ML group with more increase in blood pressure and heart rate, but the difference was not statistically significant. More cases of mucosal trauma were documented in GS group. Conclusion: Use of GS to facilitate intubation led to better glottic view but took a longer time to achieve endotracheal intubation. GS was associated with more hemodynamic response to intubation and mucosal injury in comparison with an ML. PMID:27212755

    Community Aged Intensive Recovery (CAIR) programs are an integral part of Aged Persons Mental Health Services (APMHS); however, no study has investigated whether a rural-based intensive program benefits older clients with severe mental illness. The current sample comprised 119 older adults who were being managed by a CAIR program from July 2011 to June 2013. Three key results were found: (a) approximately three quarters of clients admitted to the CAIR program remained treated in the community; (b) the program assisted in significantly reducing the level of psychiatric symptom severity from CAIR entry to CAIR exit; and (c) the APMHS team with the CAIR program had a lower psychiatric inpatient rate compared to the APMHS team without the program. The current study highlights the importance of delivering effective rural-based CAIR programs to older adults experiencing severe mental illness.

    In 1991 an audit of Intensive Care Services was carried out by the Northern Ireland Intensive Care Group. In conjunction with this regional overview, all patients in the Regional Intensive Care Unit, (RICU) in the Royal Victoria Hospital were assessed daily, over a 10 month period in 1990-91 and classified as conforming to either intensive care or high dependency status. These data were then used to compare adult intensive care service in Northern Ireland with recent national and international recommendations on intensive care. Ten units in Northern Ireland were surveyed. In regard to national or international guidelines, all ten were deficient to some degree. Four units had significant deficiencies; small patient numbers, lack of 'dedicated' 24 hr medical cover and or deficiencies in the provision of appropriate monitoring and or equipment. There was a large diversity in casemix among the ten units surveyed which suggested differing admission criteria. The bed occupancy of RICU was 100%. Refused admissions constituted a further 13% of unresourced workload. The lack of physically separate, dedicated high dependency unit facilities meant that 26% of bed days were devoted to HDU care (usually for "improved" intensive care unit patients not yet ready for discharge to a general ward. Achieving nationally recommended intensive care standards (on a regional basis) is probably only possible if a number of the smaller intensive care units are redesignated as high dependency units, and patients requiring intensive care are concentrated in a smaller number of larger ICUs. This will increase the frequency of interhospital transfer of critically ill patients.

    Exercise can have anti-inflammatory effects in obesity, but the optimal type and intensity of exercise are not clear. This study compared short-term high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) in terms of improvement in cardiorespiratory fitness, markers of inflammation, and glucose control in previously inactive adults at elevated risk of developing type 2 diabetes. Thirty-nine inactive, overweight/obese adults (32 women) were randomly assigned to 10 sessions over 2 wk of progressive HIIT (n = 20, four to ten 1-min sessions at ∼90% peak heart rate, 1-min rest periods) or MICT (n = 19, 20-50 min at ∼65% peak heart rate). Before and 3 days after training, participants performed a peak O2 uptake test, and fasting blood samples were obtained. Both HIIT (1.8 ± 0.4 vs. 1.9 ± 0.4 l/min, pre vs. post) and MICT (1.8 ± 0.5 vs. 1.9 ± 0.5 l/min, pre vs. post) improved peak O2 uptake (P < 0.001) and lowered plasma fructosamine (P < 0.05). Toll-like receptor (TLR) 4 (TLR4) expression was reduced on lymphocytes and monocytes after both HIIT and MICT (P < 0.05) and on neutrophils after MICT (P < 0.01). TLR2 on lymphocytes was reduced after HIIT and MICT (P < 0.05). Plasma inflammatory cytokines were unchanged after training in both groups, but MICT led to a reduction in fasting plasma glucose (P < 0.05, 5.9 ± 1.0 vs. 5.6 ± 1.0 mmol/l, pre vs. post). Ten days of either HIIT or MICT can improve cardiorespiratory fitness and glucose control and lead to reductions in TLR2 and TLR4 expression. MICT, which involved a longer duration of exercise, may be superior for reducing fasting glucose.

    Introduction: Central venous pressure (CVP) measurement is essential in the management of certain clinical situations, including cardiac failure, volume overload and sepsis. CVP measurement requires catheterization of the central vein which is invasive and may lead to complications. The aim of this study was to evaluate the accuracy of measurement of CVP using a new noninvasive method based on near infrared spectroscopy (NIRS) in a group of cardiac surgical Intensive Care Unit (ICU) patients. Methodology: Thirty patients in cardiac surgical ICU were enrolled in the study who had an in situ central venous catheter (CVC). Sixty measurements were recorded in 1 h for each patient. A total of 1800 values were compared between noninvasive CVP (CVPn) obtained from Mespere VENUS 2000 CVP system and invasive CVP (CVPi) obtained from CVC. Results: Strong positive correlation was found between CVPi and CVPn (R = 0.9272, P < 0.0001). Linear regression equation - CVPi = 0.5404 + 0.8875 × CVPn (r2 = 0.86, P < 0.001), Bland–Altman bias plots showed mean difference ± standard deviation and limits of agreement: −0.31 ± 1.36 and − 2.99 to + 2.37 (CVPi–CVPn). Conclusion: Noninvasive assessment of the CVP based on NIRS yields readings consistently close to those measured invasively. CVPn may be a clinically useful substitute for CVPi measurements with an advantage of being simple and continuous. It is a promising tool for early management of acute state wherein knowledge of CVP is helpful. PMID:27397443

    2015-01-01

    A prospective, observational, multicentre study of invasive candidosis (IC) in surgical patients in intensive care units (ICUs) was conducted from 2006 to 2008 in 72 ICUs in 14 European countries. A total of 779 patients (62.5% males, median age 63 years) with IC were included. The median rate of candidaemia was 9 per 1000 admissions. In 10.8% the infection was already present at the time of admission to ICU. Candida albicans accounted for 54% of the isolates, followed by Candida parapsilosis 18.5%, Candida glabrata 13.8%, Candida tropicalis 6%, Candida krusei 2.5%, and other species 5.3%. Infections due to C. krusei (57.9%) and C. glabrata (43.6%) had the highest crude mortality rate. The most common preceding surgery was abdominal (51.5%), followed by thoracic (20%) and neurosurgery (8.2%). Candida glabrata was more often isolated after abdominal surgery in patients ≥60 years, and C. parapsilosis was more often isolated in neurosurgery and multiple trauma patients as well as children ≤1 year of age. The most common first-line treatment was fluconazole (60%), followed by caspofungin (18.7%), liposomal amphotericin B (13%), voriconazole (4.8%) and other drugs (3.5%). Mortality in surgical patients with IC in ICU was 38.8%. Multivariate analysis showed that factors independently associated with mortality were: patient age ≥60 years (hazard ratio (HR) 1.9, p 0.001), central venous catheter (HR 1.8, p 0.05), corticosteroids (HR 1.5, p 0.03), not receiving systemic antifungal treatment for IC (HR 2.8, p <0.0001), and not removing intravascular lines (HR 1.6, p 0.02).

    Background: Proper caloric intake goals in critically ill surgical patients are unclear. It is possible that overnutrition can lead to hyperglycemia and an increased risk of infection. Objective: This study was conducted to determine whether surgical infection outcomes in the intensive care unit (ICU) could be improved with the use of hypocaloric nutritional support. Design: Eighty-three critically ill patients were randomly allocated to receive either the standard calculated daily caloric requirement of 25–30 kcal · kg–1 · d–1 (eucaloric) or 50% of that value (hypocaloric) via enteral tube feeds or parenteral nutrition, with an equal protein allocation in each group (1.5 g · kg–1 · d–1). Results: There were 82 infections in the hypocaloric group and 66 in the eucaloric group, with no significant difference in the mean (±SE) number of infections per patient (2.0 ± 0.6 and 1.6 ± 0.2, respectively; P = 0.50), percentage of patients acquiring infection [70.7% (29 of 41) and 76.2% (32 of 42), respectively; P = 0.57], mean ICU length of stay (16.7 ± 2.7 and 13.5 ± 1.1 d, respectively; P = 0.28), mean hospital length of stay (35.2 ± 4.9 and 31.0 ± 2.5 d, respectively; P = 0.45), mean 0600 glucose concentration (132 ± 2.9 and 135 ± 3.1 mg/dL, respectively; P = 0.63), or number of mortalities [3 (7.3%) and 4 (9.5%), respectively; P = 0.72]. Further analyses revealed no differences when analyzed by sex, admission diagnosis, site of infection, or causative organism. Conclusions: Among critically ill surgical patients, caloric provision across a wide acceptable range does not appear to be associated with major outcomes, including infectious complications. The optimum target for caloric provision remains elusive. PMID:25332331

    Background: The major goal of non-surgical periodontal therapy is to reduce or eliminate the subgingival pathogenic microbial flora that is known to be associated with volatile sulfur compounds (VSC). Aim: The aim of this study was, therefore, to determine the effect of non-surgical periodontal therapy on the concentration of VSC in mouth air of young adults. Subjects and Methods: Four hundred subjects, grouped into two based on the absence or presence of periodontal diseases, were involved in this study. Basic periodontal examination was used for the grouping. The measurement of the concentration of the VSC in the mouth air of the subjects was done objectively, using the Halimeter, before and after the therapy, and at recall visits 2 weeks and 6 weeks after therapy. Chi-square and Paired t-test were used to find statistical significance. Results: The results revealed that at baseline, 78.7% (48/61) of the subjects who had VSC concentration more than 250 parts per billion (ppb) were from the group with periodontal disease. Immediately after non-surgical periodontal therapy, only 8.5% (17/200) of the subjects with periodontal disease had VSC concentration of more than 250 ppb while all the subjects with no periodontal disease had VSC concentration less than 181 ppb. The same pattern of reduction in the concentration of the VSC and improvement in oral hygiene was also obtained 2 weeks and 6 weeks after therapy. Conclusion: It can be concluded that non-surgical periodontal therapy brought about reduction in the concentration of volatile sulfur compounds in mouth air of young adults. PMID:24116328

    Excessive bleeding and allogeneic transfusion during adult post-cardiotomy venoarterial extracorporeal membrane oxygenation (ECMO) are potentially harmful and expensive. Balancing the inhibition of clotting and distinguishing surgical from non-surgical bleeding in post-operative period is difficult. The sensitivity of coagulation tests including Thromboelastography(®) (TEG) to predict chest tube drainage in the early hours of ECMO was examined with the use of receiver-operating characteristics (ROC). The results are useful to incorporate in clinical evidence-based algorithms to guide management decisions. In the eighth hour of ECMO, 26 of the 53 adult patients (49%) studied were identified as non-bleeders (less than 2.0 mL/kg/h). All had experienced various types of cardiac surgical procedures. Fifty-two percent were female and the group was 54 ± 19 (mean ± 1 SD) years old. The coagulation parameter threshold with the maximum sensitivity and specificity to predict non-bleeding at 8 hours on ECMO was the kaolin plus heparinase TEG maximum amplitude (KH-TEG MA) at a significant ROC threshold (t) > 50 mm. The activated partial thromboplastin time (aPTT) t < 49 seconds, KH-TEG alpha-angle t > 51°, and the kaolin activated clotting time (ACT) t < 148 seconds were sensitive predictors of non-bleeders. The whole-blood KH-TEG MA was superior to the plasma-based aPTT or International Normalization Ratio (INR) to predict bleeding in the eighth hour of ECMO. Using coagulation laboratory thresholds that predict non-bleeding can begin a process of identifying patients earlier that are likely to bleed. Awareness of these parameter thresholds may improve care through patient protection from unnecessary transfusion and prolonging the life of the ECMO circuit. An algorithm incorporating the ROC thresholds was created to help recognize surgical bleeding to minimize unnecessary transfusions. PMID:27578897

  14. The immediate impact of opening an adult high dependency unit on intensive care unit occupancy.

    We assessed the hourly occupancy of our intensive care and high dependency units over an 8-week period commencing on the day our high dependency unit opened. Using criteria established by the working group on 'Guidelines on Admission to and Discharge from Intensive Care and High Dependency Units' published by the National Health Service Executive, we defined each patient daily as intensive care or high dependency status. Compared with hourly occupancy figures obtained before the high dependency unit opened, occupancy of the intensive care unit by high dependency patients has been shown to decrease significantly from 21.6% to 11.2%. Use of intensive care beds became more appropriate, their occupancy increasing significantly from 63.7% to 73.4%. A significant decrease in readmissions occurred, supporting the hypothesis that having high dependency beds reduces the number of patients discharged prematurely to the wards.

    The purpose of this study was to examine the impact of acute high-intensity interval training (HIIT) compared with continuous moderate-intensity (CMI) exercise on postprandial hyperglycemia in overweight or obese adults. Ten inactive, overweight or obese adults (41 ± 11 yrs, BMI = 36 ± 7 kg/m(2)) performed an acute bout of HIIT (10 × 1 min at approximately 90% peak heart rate (HRpeak) with 1-min recovery periods) or matched work CMI (30 min at approximately 65% HRpeak) in a randomized, counterbalanced fashion. Exercise was performed 2 h after breakfast, and glucose control was assessed by continuous glucose monitoring under standardized dietary conditions over 24 h. Postprandial glucose (PPG) responses to lunch, dinner, and the following day's breakfast were analyzed and compared with a no-exercise control day. Exercise did not affect the PPG responses to lunch, but performing both HIIT and CMI in the morning significantly reduced the PPG incremental area under the curve (AUC) following dinner when compared with control (HIIT = 110 ± 35, CMI = 125 ± 34, control = 162 ± 46 mmol/L × 2 h, p < 0.05). The PPG AUC (HIIT = 125 ± 53, CMI = 186 ± 55, control = 194 ± 96 mmol/L × 2 h) and the PPG spike (HIIT = Δ2.1 ± 0.9, CMI = Δ3.0 ± 0.9, control = Δ3.0 ± 1.5 mmol/l) following breakfast on the following day were significantly lower following HIIT compared with both CMI and control (p < 0.05). Absolute AUC and absolute glucose spikes were not different between HIIT, CMI, or control for any meal (p > 0.05 for all). We conclude that a single session of HIIT has greater and more lasting effects on reducing incremental PPG when compared with CMI.

    Exercise can have anti-inflammatory effects in obesity, but the optimal type and intensity of exercise are not clear. This study compared short-term high-intensity interval training (HIIT) with moderate-intensity continuous training (MICT) in terms of improvement in cardiorespiratory fitness, markers of inflammation, and glucose control in previously inactive adults at elevated risk of developing type 2 diabetes. Thirty-nine inactive, overweight/obese adults (32 women) were randomly assigned to 10 sessions over 2 wk of progressive HIIT (n = 20, four to ten 1-min sessions at ∼90% peak heart rate, 1-min rest periods) or MICT (n = 19, 20-50 min at ∼65% peak heart rate). Before and 3 days after training, participants performed a peak O2 uptake test, and fasting blood samples were obtained. Both HIIT (1.8 ± 0.4 vs. 1.9 ± 0.4 l/min, pre vs. post) and MICT (1.8 ± 0.5 vs. 1.9 ± 0.5 l/min, pre vs. post) improved peak O2 uptake (P < 0.001) and lowered plasma fructosamine (P < 0.05). Toll-like receptor (TLR) 4 (TLR4) expression was reduced on lymphocytes and monocytes after both HIIT and MICT (P < 0.05) and on neutrophils after MICT (P < 0.01). TLR2 on lymphocytes was reduced after HIIT and MICT (P < 0.05). Plasma inflammatory cytokines were unchanged after training in both groups, but MICT led to a reduction in fasting plasma glucose (P < 0.05, 5.9 ± 1.0 vs. 5.6 ± 1.0 mmol/l, pre vs. post). Ten days of either HIIT or MICT can improve cardiorespiratory fitness and glucose control and lead to reductions in TLR2 and TLR4 expression. MICT, which involved a longer duration of exercise, may be superior for reducing fasting glucose. PMID:26139217

    Ketamine is a unique anesthetic drug that provides analgesia, hypnosis, and amnesia with minimal respiratory and cardiovascular depression. Because of its sympathomimetic properties it would seem to be an excellent choice for patients with depressed ventricular function in cardiac surgery. However, its use has not gained widespread acceptance in adult cardiac surgery patients, perhaps due to its perceived negative psychotropic effects. Despite this limitation, it is receiving renewed interest in the United States as a sedative and analgesic drug for critically ill-patients. In this manuscript, the authors provide an evidence-based clinical review of ketamine use in cardiac surgery patients for intensive care physicians, cardio-thoracic anesthesiologists, and cardio-thoracic surgeons. All MEDLINE indexed clinical trials performed during the last 20 years in adult cardiac surgery patients were included in the review. PMID:25849690

    Purpose: To report the long-term outcome after total body irradiation with intensity-modulating compensators and allogeneic/autologous transplantation, especially in terms of therapy-related toxicity in pediatric and adult cohorts. Methods and Materials: A total of 257 consecutive patients (40 children and 217 adults) have been treated since 1983 with TBI using static intensity-modulated radiotherapy for hematologic malignancies. The total dose of 12 Gy was applied in six fractions within 3 days before allogeneic (n = 174) or autologous (n = 83) transplantation. The median follow-up was 9.2 years. Results: The 5-year overall survival rate was 47.9% (49.8% for the adults and 37.5% for the children, p = 0.171). The 5-year tumor-related mortality rate was 23%, and the 5-year treatment-related mortality rate 29.2% (29.5% in the adults and 27.5% in the pediatric patients). Interstitial pneumonitis developed in 28 (10.9%) of 257 patients and in 12.5% of the pediatric cohort. The interstitial pneumonitis rate was 25% in pediatric patients treated with a 12-Gy lung dose compared with 4.2% for those treated to an 11-Gy lung dose. The overall survival rate stratified by lung dose was 26.7% for 12 Gy and 52.4% for 11 Gy (p = 0.001). The incidence of veno-occlusive disease and cataract was 5.8% and 6.6% in all patients and 12.5% and 15% in the pediatric patients, respectively (p < 0.05). Secondary malignancies were found in 4.3% of all patients, all in the adult cohort at transplantation. Conclusion: Static intensity-modulated total body irradiation with a total dose of 12 Gy before allogeneic/autologous transplantation is a successful treatment with good long-term outcome and acceptable therapy-related toxicities. Constraining the lung dose to 11 Gy substantially lowered the actuarial treatment-related mortality. This effect was especially striking in the pediatric patients.

    High-intensity interval training (HIIT) has many known physiological benefits, but research investigating the psychological aspects of this training is limited. The purpose of the current study is to investigate the affective and enjoyment responses to continuous and high-intensity interval exercise sessions. Twenty overweight-to-obese, insufficiently active adults completed four counterbalanced trials: a 20-min trial of heavy continuous exercise and three 24-min HIIT trials that used 30-s, 60-s, and 120-s intervals. Affect declined during all trials (p < .05), but affect at the completion of trials was more positive in the shorter interval trials (p < .05). Enjoyment declined in the 120-s interval and heavy continuous conditions only (p < .05). Postexercise enjoyment was higher in the 60-s trial than in the 120-s trial and heavy continuous condition (p < .05). Findings suggest that pleasure and enjoyment are higher during shorter interval trials than during a longer interval or heavy continuous exercise.

    Hemiparesis-disability and muscle weakness of 1 side of the body-is a common consequence of stroke. High-intensity strength training may be beneficial to regain function, but strength coaches in the field of rehabilitation need evidence-based guidelines. The purpose of this study was to evaluate the effect of intensive physical rehabilitation on neuromuscular and functional adaptations in outpatients suffering from hemiparesis after stroke. A within-subject repeated-measures design with the paretic leg as the experimental leg and the nonparetic leg as the control leg was used. Eleven outpatients with hemiparesis after stroke participated in 12 weeks of intensive physical rehabilitation comprising unilateral high-intensity strength training with near-maximal loads (4-12 repetition maximum) and body weight supported treadmill training. At baseline and 12-week follow-up, the patients went through testing consisting of isokinetic muscle strength, neuromuscular activation measured with electromyography (EMG), electrically evoked muscle twitch contractile properties, and gait performance (10-m Walk Test and 6-min Walk Test). After the 12-week conditioning program, knee extensor and flexor strength increased during all contraction modes and velocities in the paretic leg. Significant increases were observed for agonist EMG amplitude at slow concentric and slow eccentric contraction. Twitch torque increased, whereas twitch time-to-peak tension remained unchanged. By contrast, no significant changes were observed in the nonparetic control leg. Gait performance increased 52-68%. In conclusion, intensive physical rehabilitation after stroke leads to clinically relevant neuromuscular improvements, leading to increased voluntary strength during a wide range of contraction modes and velocities, and improved gait velocity. Strength training coaches working in the field of rehabilitation can use this knowledge to safely and efficiently add high-intensity strength training to

    In addition to cognitive impairment, young adults with intellectual disabilities (IDs) are also more likely to be in poor health. Exercise may help ameliorate both of these deficits. While the health benefits of exercise are well documented and understood, the cognitive benefits of exercise are emerging. Exercise has been shown to improve the cognitive function of young, old, and diseased populations but few studies have evaluated the effect of exercise training on the cognitive functioning of individuals with IDs. The purpose of this study was to determine the effect of moderate-intensity exercise training on the cognitive function of young adults with IDs. Fourteen students (age, 19.4 ± 1.3 years) with mild to moderate IDs participated in an 8-week comprehensive exercise intervention program based on circuit training, aerobic dancing, and adapted sport activities. Sessions lasted 45 minutes, and intensity was maintained at 60-70% of maximum heart rate (HR(max)). Aerobic fitness was assessed via the Young Men's Christian Association (YMCA) step test, and intellectual functioning was assessed via 3 subtests from the Woodcock-Johnson III Tests of Cognitive Abilities once before and after the intervention. Performance was significantly improved on all 3 cognitive tests (all, p < 0.002). Aerobic fitness also significantly improved (p < 0.002). The mean percent increase in processing speed, a measure taking into account each individual's performance on the 3 subtests, was 103%. The mean individual improvement in aerobic fitness was 17.5%. Moderate-intensity exercise training can yield robust improvements in the cognitive functioning and aerobic fitness of young adults with IDs. These effects support the inclusion of exercise into the lives of young adults with ID to promote their physical and cognitive health. Fourteen students (age, 19.4 ± 1.3 years) with mild to moderate IDs participated in an 8-week comprehensive exercise intervention program based on circuit

    We hypothesized that high-intensity interval training (HIIT) would be more effective than moderate-intensity continuous training (MICT) at improving endothelial function and maximum oxygen uptake (V̇o2 max) in obese adults. Eighteen participants [35.1 ± 8.1 (SD) yr; body mass index = 36.0 ± 5.0 kg/m(2)] were randomized to 8 wk (3 sessions/wk) of either HIIT [10 × 1 min, 90-95% maximum heart rate (HRmax), 1-min active recovery] or MICT (30 min, 70-75% HRmax). Brachial artery flow-mediated dilation (FMD) increased after HIIT (5.13 ± 2.80% vs. 8.98 ± 2.86%, P = 0.02) but not after MICT (5.23 ± 2.82% vs. 3.05 ± 2.76%, P = 0.16). Resting artery diameter increased after MICT (3.68 ± 0.58 mm vs. 3.86 ± 0.58 mm, P = 0.02) but not after HIIT (4.04 ± 0.70 mm vs. 4.09 ± 0.70 mm; P = 0.63). There was a significant (P = 0.02) group × time interaction in low flow-mediated constriction (L-FMC) between MICT (0.63 ± 2.00% vs. -2.79 ± 3.20%; P = 0.03) and HIIT (-1.04 ± 4.09% vs. 1.74 ± 3.46%; P = 0.29). V̇o2 max increased (P < 0.01) similarly after HIIT (2.19 ± 0.65 l/min vs. 2.64 ± 0.88 l/min) and MICT (2.24 ± 0.48 l/min vs. 2.55 ± 0.61 l/min). Biomarkers of cardiovascular risk and endothelial function were unchanged. HIIT and MICT produced different vascular adaptations in obese adults, with HIIT improving FMD and MICT increasing resting artery diameter and enhancing L-FMC. HIIT required 27.5% less total exercise time and ∼25% less energy expenditure than MICT. PMID:27255523

    OBJECTIVE. To investigate the distribution of hospital pathogens within general and critical care ward environments and to determine the most significant bacterial reservoirs within each ward type. DESIGN. Prospective 4-month microbiological survey. SETTING. The intensive care unit (ICU) and gastrointestinal (GI) surgical ward of a London teaching hospital. PATIENTS. Sampling was conducted in and around the bed space of 166 different patients (99 in the ICU and 67 in the GI ward). METHODS. Conventional agar contact methodology was used to sample 123 predetermined sites twice a week for 17 weeks. Sixty-one surfaces were located within the ICU, and 62 were located within the GI ward. Each surface was located within a theoretical zone of increasing distance from the patient. Aerobic colony counts were determined, and confirmatory testing was conducted on all presumptive pathogens. RESULTS. Regardless of ward type, surfaces located closest to the patient, specifically those associated with the bed (side rails, bed control, and call button), were the most heavily contaminated. Elsewhere, the type of surfaces contaminated differed with ward type. In the ICU, bacteria were most likely to be on surfaces that were regularly touched by healthcare workers (e.g., telephones and computer keyboards). In the GI ward, where the patients were mobile, the highest numbers of bacteria (including potential nosocomial pathogens) were on surfaces that were mainly touched by patients, particularly their toilet and shower facilities. CONCLUSIONS. In terms of cleaning, a hospital should not be considered a single entity. Different ward types should be treated as separate environments, and cleaning protocols should be adjusted accordingly.

    Importance Cancer is the leading disease-related cause of death among adolescents and young adults (AYAs), but little is known about the care that AYA patients with cancer receive at the end of life (EOL). Objective To evaluate the intensity of EOL care among AYA cancer patients. Design Cross-sectional study using cancer registry and electronic health record data. Setting Kaiser Permanente Southern California (KSPC), an integrated health care delivery system. Participants 663 AYA patients with either (1) stage I-III cancer and evidence of cancer recurrence or (2) stage IV cancer at diagnosis who received care in KPSC and died in the years 2001–2010. Patients were eligible if they were aged 15–39 at death. Main Outcome Measures Chemotherapy use in the last 14 days of life, intensive care unit (ICU) care in the last 30 days of life, more than one emergency room (ER) visit in the last 30 days of life, hospitalization in the last 30 days of life, and a composite measure of medically intensive EOL care comprising any of the aforementioned measures. Results 11% of patients (72/663) received chemotherapy within 14 days of death. In the last 30 days of life, 22% of patients (144/663) were admitted to the ICU; 22% (147/663) had >1 ER visit; and 62% (413/663) were hospitalized. Overall, 68% (449/663) of subjects received at least one medically intensive EOL care measure. Conclusions and Relevance Most AYA patients receive at least one form of medically intensive EOL care. These findings suggest the need to better understand EOL care preferences and decision-making in this young population. PMID:26181778

    Evidence supporting a taste component for dietary fat has prompted study of plausible transduction mechanisms. One hypothesizes that long-chain, unsaturated fatty acids block selected delayed-rectifying potassium channels, resulting in a sensitization of taste receptor cells to stimulation by other taste compounds. This was tested in 17 male and 17 female adult (mean +/- SE age = 23.4 +/- 0.7 yr) propylthiouracil tasters with normal resting triglyceride concentrations (87.3 +/- 5.6 mg/day) and body mass index (23.3 +/- 0.4 kg/m(2)). Participants were tested during two approximately 30-min test sessions per week for 8 wk. Eight stimuli were assessed in duplicate via an ascending, three-alternative, forced-choice procedure. Qualities were randomized over weeks. Stimuli were presented as room-temperature, 5-ml portions. They included 1% solutions of linoleic acid with added sodium chloride (salty), sucrose (sweet), citric acid (sour), and caffeine (bitter) as well as solutions of these taste compounds alone. Participants also rated the intensity of the five strongest concentrations using the general labeled magnitude scale. The suprathreshold samples were presented in random order with a rinse between each. Subjects made the ratings self-paced while wearing nose clips. It was hypothesized that taste thresholds would be lower and absolute intensity ratings or slopes of intensity functions would be higher for the stimuli mixed with the linoleic acid. Thresholds were compared by paired t-tests and intensity ratings by repeated measures analysis of variance. Thresholds were significantly higher (i.e., lower sensitivity) for the sodium chloride, citric acid, and caffeine solutions with added fatty acid. Sweet, sour, and salty intensity ratings were lower or unchanged by the addition of a fatty acid. The two highest concentrations of caffeine were rated as weaker in the presence of linoleic acid. These data do not support a mechanism for detecting dietary fats whereby fatty

    In this study, we randomly compared high doses of the tyrosine kinase inhibitor imatinib combined with reduced-intensity chemotherapy (arm A) to standard imatinib/hyperCVAD (cyclophosphamide/vincristine/doxorubicin/dexamethasone) therapy (arm B) in 268 adults (median age, 47 years) with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). The primary objective was the major molecular response (MMolR) rate after cycle 2, patients being then eligible for allogeneic stem cell transplantation (SCT) if they had a donor, or autologous SCT if in MMolR and no donor. With fewer induction deaths, the complete remission (CR) rate was higher in arm A than in arm B (98% vs 91%; P = .006), whereas the MMolR rate was similar in both arms (66% vs 64%). With a median follow-up of 4.8 years, 5-year event-free survival and overall survival (OS) rates were estimated at 37.1% and 45.6%, respectively, without difference between the arms. Allogeneic transplantation was associated with a significant benefit in relapse-free survival (hazard ratio [HR], 0.69; P = .036) and OS (HR, 0.64; P = .02), with initial white blood cell count being the only factor significantly interacting with this SCT effect. In patients achieving MMolR, outcome was similar after autologous and allogeneic transplantation. This study validates an induction regimen combining reduced-intensity chemotherapy and imatinib in Ph+ ALL adult patients and suggests that SCT in first CR is still a good option for Ph+ ALL adult patients. This trial was registered at www.clinicaltrials.gov as #NCT00327678. PMID:25878120

    In this study, we randomly compared high doses of the tyrosine kinase inhibitor imatinib combined with reduced-intensity chemotherapy (arm A) to standard imatinib/hyperCVAD (cyclophosphamide/vincristine/doxorubicin/dexamethasone) therapy (arm B) in 268 adults (median age, 47 years) with Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL). The primary objective was the major molecular response (MMolR) rate after cycle 2, patients being then eligible for allogeneic stem cell transplantation (SCT) if they had a donor, or autologous SCT if in MMolR and no donor. With fewer induction deaths, the complete remission (CR) rate was higher in arm A than in arm B (98% vs 91%; P = .006), whereas the MMolR rate was similar in both arms (66% vs 64%). With a median follow-up of 4.8 years, 5-year event-free survival and overall survival (OS) rates were estimated at 37.1% and 45.6%, respectively, without difference between the arms. Allogeneic transplantation was associated with a significant benefit in relapse-free survival (hazard ratio [HR], 0.69; P = .036) and OS (HR, 0.64; P = .02), with initial white blood cell count being the only factor significantly interacting with this SCT effect. In patients achieving MMolR, outcome was similar after autologous and allogeneic transplantation. This study validates an induction regimen combining reduced-intensity chemotherapy and imatinib in Ph+ ALL adult patients and suggests that SCT in first CR is still a good option for Ph+ ALL adult patients. This trial was registered at www.clinicaltrials.gov as #NCT00327678.

    To guide family adjustment, an effort was made to facilitate pediatric visitation in an adult intensive care unit (ICU). Goals were to improve customer satisfaction and to raise staff comfort level with child visitation. After implementing an open visitation policy, concerns around pediatric visitation in the ICU remained. Fears centered on risks to both patient and child. Literature was reviewed before a book was written entitled A Visit to the ICU. It contained information about what a child visiting the ICU would see, hear, and feel when visiting a loved one. The book provided reassurance for caregivers and children, informing them about what to expect when visiting. The goal of the book was to provide caregivers with a framework for age-appropriate education. Staff education was provided on developmental stages, including a child's understandings of illness and death. Nursing interventions were reviewed and resources provided. A survey demonstrated that the book increased staff comfort level with children visiting the unit, was a positive tool for patients and families, and eased fears among children while helping to facilitate coping mechanisms. The article will describe the practice change of pediatric visitation in an ICU and how it could be applied to other critical care settings. PMID:22157497

    The objective of this study was to explore which of many personal and environmental variables are the best predictors of reintegration to normal living in older adults discharged from an inpatient rehabilitation unit. A few days before discharge from rehabilitation, more than 15 biopsychosocial characteristics of 94 people over 60 years were evaluated with reliable and valid tests. The participants' reintegration to normal living was evaluated 3 months later (n=86) with the reintegration to normal living index. This questionnaire comprises 11 items covering physical, social, and psychological dimensions of daily living. From multivariate regression analyses, functional independence, balance, grip strength, and general well-being are the best predictors and explain 26 and 27% of the variance in reintegration to normal living. This study suggests that by increasing efforts to maximize functional independence, balance, grip strength, and well-being, rehabilitation professionals can expect older adults to achieve a greater degree of reintegration in their activities and social roles and may contribute to their quality of life.

    In this article a phenomenological qualitative research study is discussed. More attention will be given to the methodology of the research. The objectives of the study are two-fold: firstly to explore and describe the experience of registered nurses nursing in the adult intensive care unit (this is the first phase of the research) and to describe guidelines based on the information obtained in the first phase to support the nurses in the form of a support programme in the second phase. The units of research are the registered nurses in the intensive care unit. The characteristics of the unit of research led to the emergence of a qualitative phenomenological research design of an explorative, descriptive and contextual nature. In the discussion of research methodology attention will be given to phase one: data gathering (ethical considerations and informed consent; purposive selection, phenomenological interviews and field notes); data analysis (Tesch's method of data analysis, methods to ensure trustworthiness, organisation of raw data and integration of findings supported by literature. Five themes were identified through the data analysis: impaired communication with management; discrimination: white on black racism; lack of fair, competitive remuneration and disregard for professional worth; non-conducive physical environment, and stressful working environment. Phase two: Guidelines were described to support the registered nurses in the intensive care unit based on the information obtained in phase one of the research.

    Background: Walking is one of the most commonly recommended activities for sedentary individuals. When performed at the correct intensity, it can provide cardiovascular, respiratory, metabolic, and other benefits by providing a training effect in addition to reducing the risk of death from cardiovascular diseases and other chronic health conditions. Objectives: The primary aim of this study was to assess whether individuals who practiced regular unsupervised walking carry out the activity safely and with sufficient effort intensity parameters to have a positive physiological (training) effect. The secondary objective was to compare the training heart rate (HR) and the stability of the HR within the ideal range of training between the sexes. Method: Individuals were selected from walking tracks within the city of Belo Horizonte, Brazil. The study included subjects from 40 to 60 years of age who had practiced walking for at least two months prior to the study, walking at least three times a week. Individuals who agreed to participate in the survey were asked to walk 15 minutes at their usual pace with their HR measured every 5 minutes using a heart rate monitor. Their average walking HR was compared to the average training HR based on the formula: (220 - age) × 70 to 80% that would result in a positive physiological training effect. Results: Of the 142 individuals evaluated, 25.4% achieved the average training HR. This result was significantly lower than those who did not achieve the average training HR while walking (p=0.002). There were significant differences between men and women who had reached the training HR (p=0.0001). Conclusion: The authors found that individuals who walk regularly performed outside the range of the ideal HR intensity that would cause a positive physiological effect and therefore would probably not achieve a beneficial training effect while walking.

    Stepping is a convenient form of scalable high-intensity interval training (HIIT) that may lead to health benefits. However, the accurate personalised prescription of stepping is hampered by a lack of evidence on optimal stepping cadences and step heights for various populations. This study examined the acute physiological responses to stepping exercise at various heights and cadences in young (n = 14) and middle-aged (n = 14) females in order to develop an equation that facilitates prescription of stepping at targeted intensities. Participants completed a step test protocol consisting of randomised three-minute bouts at different step cadences (80, 90, 100, 110 steps·min-1) and step heights (17, 25, 30, 34 cm). Aerobic demand and heart rate values were measured throughout. Resting metabolic rate was measured in order to develop female specific metabolic equivalents (METs) for stepping. Results revealed significant differences between age groups for METs and heart rate reserve, and within-group differences for METs, heart rate, and metabolic cost, at different step heights and cadences. At a given step height and cadence, middle-aged females were required to work at an intensity on average 1.9 ± 0.26 METs greater than the younger females. A prescriptive equation was developed to assess energy cost in METs using multilevel regression analysis with factors of step height, step cadence and age. Considering recent evidence supporting accumulated bouts of HIIT exercise for health benefits, this equation, which allows HIIT to be personally prescribed to inactive and sedentary women, has potential impact as a public health exercise prescription tool.

    After having experienced more than 2,000 cases of adult living donor liver transplantation (LDLT), we established the concepts of right liver graft standardization. Right liver graft standardization intends to provide hemodynamics-based and regeneration-compliant reconstruction of vascular inflow and outflow. Right liver graft standardization consists of the following components: Right hepatic vein reconstruction includes a combination of caudal-side deep incision and patch venoplasty of the graft right hepatic vein to remove the acute angle between the graft right hepatic vein and the inferior vena cava; middle hepatic vein reconstruction includes interposition of a uniform-shaped conduit with large-sized homologous or prosthetic grafts; if the inferior right hepatic vein is present, its reconstruction includes funneling and unification venoplasty for multiple short hepatic veins; if donor portal vein anomaly is present, its reconstruction includes conjoined unification venoplasty for two or more portal vein orifices. This video clip that shows the surgical technique from bench to reperfusion was a case presentation of adult LDLT using a modified right liver graft from the patient's son. Our intention behind proposing the concept of right liver graft standardization is that it can be universally applicable and may guarantee nearly the same outcomes regardless of the surgeon's experience. We believe that this reconstruction model would be primarily applied to a majority of adult LDLT cases. PMID:27621745

    Background: Biotinidase deficiency (BD) is a rare, inherited autosomal recessive disorder that is treatable within childhood. We present a patient with pneumonia and respiratory acidosis who was not diagnosed with any systemic disorders; the patient was finally diagnosed as BD. Case Report: A thirty-year-old woman was admitted to the emergency department with respiratory failure that had persisted for a few days and progressively weakening over the previous six months. Then, the patient was admitted to the intensive care unit with marked respiratory acidosis, respiratory failure and alterations in consciousness. At the follow-up, the patient was not diagnosed with a systematic disorder. Rather, the patient’s historical clinical findings suggested a metabolic disorder. Finally, the patient was diagnosed with biotinidase deficiency. Conclusion: Even though biotinidase deficiency is not frequently seen in the intensive care unit, metabolic syndromes such as biotinidase deficiency should be considered. Patients should be evaluated holistically with attention to medical history, family history and clinical findings. PMID:27761288

    Purpose. To define the maximally tolerated dose (MTD) of ifosfamide when given with G-CSF on an every other week schedule, and to define the MTD of edatrexate that can be given every two weeks with an intense schedule of ifosfamide. Patients and Methods. Forty-one patients with metastatic or unresectable, locally advanced sarcoma participated in this 2-step phase I trial.The starting dose of ifosfamide was 10 gm/m2 given by continuous intravenous infusion over 4 days every 2 weeks.When the MTD was defined, edatrexate, beginning at a dose of 40 mg/m2 intravenously every 2 weeks was added in subsequent cohorts of patients. Results. Myelosuppression was the most prominent toxicity. Fatigue, nausea, and vomiting were observed in the majority of patients. Ifosfamide 12 gm/m2 given every 2 weeks approached or exceeded the MTD. Edatrexate 100 mg/m2 could be given safety as an intravenous bolus with ifosfamide 10 gm/m2 every 2 weeks. Therapeutic responses were observed in patients with measurable disease. Conclusions. This study demonstrates the feasibility of administering a dose-intense schedule of ifosfamide alone or ifosfamide with edatrexate that might be applied in the adjuvant or neo-adjuvant setting.

    Continuous EEG monitoring in the ICU is different from planned EEG due to the rather urgent nature of the indications, explaining the fact that recording is started in certain cases by the clinical team in charge of the patient's care. Close collaboration between neurophysiology teams and intensive care teams is essential. Continuous EEG monitoring can be facilitated by quantified analysis systems. This kind of analysis is based on certain signal characteristics, such as amplitude or frequency content, but raw EEG data should always be interpreted if possible, since artefacts can sometimes impair quantified EEG analysis. It is preferable to work within a tele-EEG network, so that the neurophysiologist has the possibility to give an interpretation on call. Continuous EEG monitoring is thus useful in the diagnosis of non-convulsive epileptic seizures or purely electrical discharges and in the monitoring of status epilepticus when consciousness disorders persist after initial treatment. A number of other indications are currently under evaluation.

    This descriptive study was intended to measure the percentage of the time that patient beds were kept in high position in an adult acute inpatient surgical unit with medical overflow in a community hospital in Michigan, United States. The percentage of the time was calculated for morning, evening, and night shifts. The results showed that overall, occupied beds were in a high position 5.6% of the time: 5.40% in the day shift, 6.88% in the evening shift, and 4.38% in the night shift. It is recognized that this study was unable to differentiate whether those times patient beds being kept in a high position were appropriate for an elevated bed height (e.g., staff were working with the patient). Further research is warranted. Falls committees may conduct high-bed prevalence surveys in a regular basis as a proxy to monitor staff members' behaviors in keeping beds in a high position.

    Background Safe Male Circumcision is a proven approach for partial HIV prevention. Several sub Saharan African countries have plans to reach a prevalence of 80% of their adult males circumcised by 2015. These targets require out of ordinary organization, demand creation, timely execution and perhaps the use of SMC devices. Objective To profile Adverse Events rate and acceptance of PrePex, a non surgical device for adult male circumcision. Methods A prospective study, conducted at International Hospital Kampala, Uganda, between August and October 2012. Ethical approval was obtained from Uganda National Council of Science and Technology. Results Of 1,040 men received to undergo SMC, 678 opted for PrePex, 36 were excluded at an initial physical examination screening. 642 were enrolled and consented, and another 17 were excluded before device placement. 625 underwent the procedure. Average age was 24 years (±7). Twelve moderate AEs occurred among 10 participants 12/625, (1.9%). These were all reversible. Five had device displacement, one had an everted foreskin; five had bleeding after the device was removed and one had voiding difficulties. The majority (279 out of 300) of men interviewed complained of some pain within the week of placement. Mean pain score at device placement (using visual analogue scale) was 0.5, at device removal 4.5 and within 2 min of removal the pain score was 1.4. Over 70% of the devices were placed and removed by non-physician clinicians. Presented with a choice, 60% of men chose PrePex over surgical SMC. Close to 90% would recommend the device to their friends. Odour from the necrotic skin was a concern. Removals done 1–2 days earlier than day 7 were beneficial and conferred no extra risk. Conclusion AEs of a moderate or severe nature associated with PrePex were low and reversible. PrePex is feasible for mass safe male circumcision scaling up. PMID:24489754

    Background Research suggests that interaction between humans and digital environments characterizes a form of companionship in addition to technical convenience. To this effect, humans have attempted to design computer systems able to demonstrably empathize with the human affective experience. Facial electromyography (EMG) is one such technique enabling machines to access to human affective states. Numerous studies have investigated the effects of valence emotions on facial EMG activity captured over the corrugator supercilii (frowning muscle) and zygomaticus major (smiling muscle). The arousal emotion, specifically, has not received much research attention, however. In the present study, we sought to identify intensive valence and arousal affective states via facial EMG activity. Methods Ten blocks of affective pictures were separated into five categories: neutral valence/low arousal (0VLA), positive valence/high arousal (PVHA), negative valence/high arousal (NVHA), positive valence/low arousal (PVLA), and negative valence/low arousal (NVLA), and the ability of each to elicit corresponding valence and arousal affective states was investigated at length. One hundred and thirteen participants were subjected to these stimuli and provided facial EMG. A set of 16 features based on the amplitude, frequency, predictability, and variability of signals was defined and classified using a support vector machine (SVM). Results We observed highly accurate classification rates based on the combined corrugator and zygomaticus EMG, ranging from 75.69% to 100.00% for the baseline and five affective states (0VLA, PVHA, PVLA, NVHA, and NVLA) in all individuals. There were significant differences in classification rate accuracy between senior and young adults, but there was no significant difference between female and male participants. Conclusion Our research provides robust evidences for recognition of intensive valence and arousal affective states in young and senior adults. These

    Acute lymphoblastic leukemia (ALL) with high-risk features has a poor prognosis in adults despite aggressive chemotherapy. Reduced-intensity conditioning (RIC) is a lower toxicity alternative for high-risk patients requiring hematopoietic cell transplantation (HCT), however it has not been widely used for ALL. We conducted a retrospective study of 24 high-risk adult ALL patients who received an RIC regimen of fludarabine/melphalan prior to allogeneic peripheral blood stem cell transplant between 6/14/02 and 6/15/07 at City of Hope. Indications for the RIC regimen were: 1) age 50 or older (42%), 2) compromised organ function (54%), or 3) recipient of a previous HCT (37.5%). Patients had a median age of 47.5 years and the median follow-up was 28.5 months for living patients. Both overall survival and disease-free survival at two years was 61.5%. Relapse incidence was 21.1% and non-relapse mortality was 21.5% at two years. cGVHD developed in 86% of evaluable patients. In this series, no significant correlations were made between outcomes and patient age, presence of Philadelphia chromosome, relatedness of donor source or prior HCT. These high survival rates for high-risk ALL patients following RIC HCT may offer a promising option for patients not eligible for a standard myeloablative transplant. PMID:19822300

    Haploidentical SCT (HaploSCT) has been most commonly performed using a myeloablative, TBI-based preparative regimen; however, the toxicity with this approach remains very high. We studied the feasibility of a reduced-intensity conditioning regimen in a phase II clinical trial using fludarabine, melphalan and thiotepa and antithymocyte globulin (ATG) for patients with advanced hematological malignancies undergoing T-cell depleted HaploSCT. Twenty-eight patients were entered in the study. Engraftment with donor-derived hematopoiesis was achieved in 78% of patients after a median of 13 days. Six patients experienced primary graft failure, three out of four tested patients had donor-specific anti-HLA antibodies (DSA) (P = 0.001). Toxicity included mostly infections. A total of 21 out of 22 patients with AML/myelodysplastic syndrome (MDS) achieved remission after transplant (16 with relapsed/refractory AML). Five out of the 12 patients (42%) with AML/MDS with <15% BM blasts survived long term as compared with none with more advanced disease (P = 0.03). HaploSCT with this fludarabine, melphalan and thiotepa and ATG RIC is an effective, well-tolerated conditioning regimen for patients with AML/MDS with low disease burden at the time of transplant and allowed a high rate of engraftment in patients without DSA. Patients with overt relapse fared poorly and require novel treatment strategies. PMID:19668237

    Acute exercise can positively impact cognition. The present study examined the effect of acute high-intensity aerobic exercise on prefrontal-dependent cognitive performance and brain-derived neurotrophic factor (BDNF). Fifty-eight young adults were randomly assigned to one of two experimental groups: (a) an acute bout of high-intensity exercise (n=29) or (b) a non-exercise control (n=29). Participants in the exercise group improved performance on inhibitory control in Stroop interference and on cognitive flexibility in Trail Making Test (TMT) Part-B compared with participants in the control group and increased BDNF immediately after exercise. There was a significant relationship between BDNF and TMT Part-B on the pre-post change following exercise. These findings provide support for the association between improved prefrontal-dependent cognitive performance and increased BDNF in response to acute exercise. We conclude that the changes in BDNF concentration may be partially responsible for prefrontal-dependent cognitive functioning following an acute bout of exercise. PMID:27450438

Surface electromyograms, three-dimensional motion and ground reaction forces were collected during gait before and after 20 healthy adults completed a high intensity quadriceps fatigue protocol. Pattern recognition techniques were utilized to examine changes in amplitude and temporal characteristics of all gait variables. The fatigue protocol resulted in decreased knee extensor torque generation and quadriceps median power frequencies for 18 of 20 participants (p < 0.05). The gait data from these 18 participants was analyzed. The knee external rotation angle increased (p < 0.05), the net external flexion and external rotation moments decreased (p < 0.05), and the net external adduction moment increased (p < 0.05). Post-fatigue changes in periarticular muscle activation patterns were consistent with the biomechanical changes, but were not significantly altered. Even for this low demand task of walking the knee motion and loading characteristics were altered following a high intensity fatigue protocol in a manner that may place the knee joint at greater risk for joint pathology and injury.

    Acute exercise can positively impact cognition. The present study examined the effect of acute high-intensity aerobic exercise on prefrontal-dependent cognitive performance and brain-derived neurotrophic factor (BDNF). Fifty-eight young adults were randomly assigned to one of two experimental groups: (a) an acute bout of high-intensity exercise (n=29) or (b) a non-exercise control (n=29). Participants in the exercise group improved performance on inhibitory control in Stroop interference and on cognitive flexibility in Trail Making Test (TMT) Part-B compared with participants in the control group and increased BDNF immediately after exercise. There was a significant relationship between BDNF and TMT Part-B on the pre-post change following exercise. These findings provide support for the association between improved prefrontal-dependent cognitive performance and increased BDNF in response to acute exercise. We conclude that the changes in BDNF concentration may be partially responsible for prefrontal-dependent cognitive functioning following an acute bout of exercise.

    Simple Summary The Animal Welfare Indicators (AWIN) project developed a practical welfare assessment protocol for lactating dairy goats in intensive husbandry systems, using animal-based indicators that cover the whole multidimensional concept of animal welfare. The strict collaboration between scientists and stakeholders resulted in an easy-to-use protocol that provides farmers or veterinarians with comprehensive but clear feedback on the welfare status of the herd in less than three hours. The protocol, which highlights key points and motivates farmers to achieve improvements, has received much attention from interested parties. Abstract Within the European AWIN project, a protocol for assessing dairy goats’ welfare on the farm was developed. Starting from a literature review, a prototype including animal-based indicators covering four welfare principles and 12 welfare criteria was set up. The prototype was tested in 60 farms for validity, reliability, and feasibility. After testing the prototype, a two-level assessment protocol was proposed in order to increase acceptability among stakeholders. The first level offers a more general overview of the welfare status, based on group assessment of a few indicators (e.g., hair coat condition, latency to the first contact test, severe lameness, Qualitative Behavior Assessment), with no or minimal handling of goats and short assessment time required. The second level starts if welfare problems are encountered in the first level and adds a comprehensive and detailed individual evaluation (e.g., Body Condition Score, udder asymmetry, overgrown claws), supported by an effective sampling strategy. The assessment can be carried out using the AWIN Goat app. The app results in a clear visual output, which provides positive feedback on welfare conditions in comparison with a benchmark of a reference population. The protocol may be a valuable tool for both veterinarians and technicians and a self-assessment instrument for

    The objective of this study was to determine whether overweight insulin resistant individuals who lost weight and improved cardiovascular risk factors during a 4-month lifestyle intervention could sustain these lifestyle changes in the long-term. Seventy-nine insulin resistant adults were randomised to a control group or either a modest or intensive lifestyle intervention group for 4-months. Thereafter the two intervention groups were combined and all participants were followed-up at 8, 12 and 24 months. Anthropometry, blood pressure, fasting glucose, lipids, insulin and aerobic fitness were measured and dietary intake was assessed. An interview was conducted to determine factors which participants perceived facilitated or hindered maintenance of healthy lifestyle habits. Seventy-two (91.1%), sixty-nine (87.3%) and sixty-two (78.5%) participants were retained at 8, 12 and 24-month respectively. At 4-months the adjusted difference in weight between the modest and control groups was -3.4 kg (95% CI -5.4, -1.3) p=0.002 and intensive and control groups was -4.7 kg (-6.9, -2.4) p=0.0001 respectively. At 2-years there were no significant differences for weight when the initial 3 groups were compared or when the combined intervention group was compared with the control group. At 2-years, 64% of participants reported that more frequent follow-up would have helped them to maintain healthy lifestyle habits. Even intensive counselling for 4-months with 4-monthly and then yearly monitoring were not enough for maintaining lifestyle changes sufficient to sustain weight loss. More frequent monitoring for an indefinite period was perceived by two-thirds of participants as necessary for them to maintain their initial lifestyle changes.

    Background. Acceptance of dual kidney transplantation (DKT) has proven difficult, due to surgical complexity and concerns regarding long-term outcomes. We herein present a standard technique for ipsilateral DKT and compare outcomes to single-kidney transplant (SKT) recipients. Methods. A retrospective single-center comparison of DKT and SKT performed between February 2007 and July 2013. Results. Of 516 deceased donor kidney transplants, 29 were DKT and 487 were SKT. Mean follow-up was 43 ± 67 months. DKT recipients were older and more likely than SKT recipients to receive an extended criteria graft (p < 0.001). For DKT versus SKT, the rates of delayed graft function (10.3 versus 9.2%) and acute rejection (20.7 versus 22.4%) were equivalent (p = ns). A higher than expected urologic complication rate in the DKT cohort (14 versus 2%, p < 0.01) was reduced through modification of the ureteral anastomosis. Graft survival was equivalent between DKT and SKT groups (p = ns) with actuarial 3-year DKT patient and graft survivals of 100% and 93%. At 3 years, the groups had similar renal function (p = ns). Conclusions. By utilizing extended criteria donor organs as DKT, the donor pool was enlarged while providing excellent patient and graft survival. The DKT urologic complication rate was reduced by modification of the ureteral anastomosis.

    Abstract The study aims to find whether a low intensity lifestyle modification (LILM) program was effective to achieve weight reduction and improves metabolic syndrome in young adults. Our study prospectively enrolled young adults aged 30 to 45 years with metabolic syndrome in northeastern Taiwan from June 1, 2008 to December 31, 2009. The participants in the intervention group attended a LILM program for 6 months, which included 4 interactive group discussion sessions and weekly phone contact with volunteer counselors. Participants in the comparison group, however, attended only 1 noninteractive session on diet and physical activity. The main outcomes measured the weight reduction and prevalence of metabolic syndrome in intervention and comparison groups. Generalized estimating equation modeling was used to analyze the effects at baseline, during the study, and postcompletion of the program. Compared with comparison group, the intervention group showed significantly greater reductions in body weight (−2.95 ± 3.52 vs −0.76 ± 2.76 kg, P < 0.0001) and body mass index (−1.03 ± 1.25 vs −0.30 ± 1.16 kg/m2, P < 0.0001). After adjustment for potential confounders, a modest decrease in body weight resulted in a statistically significant 43.32% resolution in the prevalence of metabolic syndrome in the intervention group compared with 33.64% in the comparison group (P < 0.01). The 6-month LILM program is not only effective in weight reduction but also an efficient intervention tool of metabolic syndrome in a community setting. The program with restricted manpower and limited medical resources can be practically transferred into primary care in rural area. PMID:26039125

    Although active gaming is popular and can increase energy expenditure in young adults, its efficacy as a prescriptive exercise tool is not well understood. This study aimed to: (a) compare the activity intensities experienced by young adults while playing active tennis gaming with conventional sedentary gaming, tennis game-play, and current activity recommendations for health; and (b) identify changes in activity intensities across playing time. After habitualization, 10 active young adults (age: 20.2 ± 0.4 years; stature: 1.74 ± 0.03 m; body mass: 67.7 ± 3.3 kg) completed 3 experimental trials (sedentary gaming, active tennis gaming, and tennis game-play) on separate days in a randomized order. Heart rate (HR) and metabolic equivalents (METs) were averaged across 5 minutes and 10 minutes intervals, and the entire 20 minutes bout within each condition. Active gaming produced greater intensities across 5-10, 10-15, and 15-20 minutes time intervals compared with sedentary gaming (p < 0.01). Tennis game-play elicited greater HR (67 ± 5% HR(max)) and METs (5.0 ± 0.2) responses than both sedentary (40 ± 2% HR(max), 1.1 ± 0.1 METs) and active gaming (45 ± 2% HR(max), 1.4 ± 0.1 METs) (p < 0.001). Only tennis game-play produced activity intensities meeting current recommendations for health benefit. Lower HR intensities were reached across 0-5 minutes than during later time intervals during active gaming (6%) and tennis game-play (9%) (p < 0.01). Activity intensities elicited by active gaming were greater than sedentary gaming but less than tennis game-play and insufficient to contribute toward promoting and maintaining good health in young adults. These data suggest that active tennis gaming should not be recommended by exercise professionals as a substitute for actual sports participation in young adults.

    This longitudinal study tracked the neuro-cognitive changes associated with second language (L2) grammar learning in adults in order to investigate how L2 processing is shaped by a learner's first language (L1) background and L2 proficiency. Previous studies using event-related potentials (ERPs) have argued that late L2 learners cannot elicit a P600 in response to L2 grammatical structures that do not exist in the L1 or that are different in the L1 and L2. We tested whether the neuro-cognitive processes underlying this component become available after intensive L2 instruction. Korean- and Chinese late-L2-learners of English were tested at the beginning and end of a 9-week intensive English-L2 course. ERPs were recorded while participants read English sentences containing violations of regular past tense (a grammatical structure that operates differently in Korean and does not exist in Chinese). Whereas no P600 effects were present at the start of instruction, by the end of instruction, significant P600s were observed for both L1 groups. Latency differences in the P600 exhibited by Chinese and Korean speakers may be attributed to differences in L1-L2 reading strategies. Across all participants, larger P600 effects at session 2 were associated with: 1) higher levels of behavioural performance on an online grammaticality judgment task; and 2) with correct, rather than incorrect, behavioural responses. These findings suggest that the neuro-cognitive processes underlying the P600 (e.g., "grammaticalization") are modulated by individual levels of L2 behavioural performance and learning.

    Neoadjuvant chemotherapy for osteosarcoma is the standard of care, but there is still confusion regarding the best chemotherapy regimen and the optimal intensity. This retrospective study intends to evaluate whether there is a clear correlation between the chemotherapy dose intensity (DI) and the percentage of tumor necrosis, the risk of tumor recurrence after surgery and patient survival. The medical records of all adult patients with localized osteosarcoma that received treatment between the years of 1998 and 2009 at the Tel Aviv Sourasky Medical Center were analyzed. We used multiple logistic/linear regression models to test the effect of the neoadjuvant chemotherapy relative DI (RDI) on histological response, recurrence and time to recurrence. A Cox regression analysis was conducted for the effects of neoadjuvant chemotherapy RDI, histological response, tumor location, gender and age on patient survival. Thirty medical records were analyzed. Survival, histological response, recurrence and time to recurrence were not affected by the chemotherapy RDI. The 5-year overall survival of the patient's population was found to be 63% with a median survival of 9.4 years. Patients with a good histological response had a longer survival than those with a bad response (mean survival times 11.0 vs. 6.6 years, log-rank test, P = 0.046). High DI is not a prognostic factor in osteosarcoma and maintaining it should not be a prime priority. Histological response is a prognostic but possibly not a reliable predictive factor, and further research is needed in order to find other reliable factors. PMID:24719037

    Background Alcohol misuse ranks within the top ten health conditions with the highest global burden of disease. Low-intensity, Internet interventions for curbing adult alcohol misuse have been shown effective. Few meta-analyses have been carried out, however, and they have involved small numbers of studies, lacked indicators of drinking within low risk guidelines, and examined the effectiveness of unguided self-help only. We therefore conducted a more thorough meta-analysis that included both guided and unguided interventions. Methods Systematic literature searches were performed up to September 2013. Primary outcome was the mean level of alcohol consumption and drinking within low risk guidelines for alcohol consumption at post-treatment. Findings We selected 16 randomised controlled trials (with 23 comparisons and 5,612 participants) for inclusion. Results, showed a small but significant overall effect size in favour of Internet interventions (g = 0.20, 95% CI: 0.13–0.27, p<.001). Participants in Internet interventions drunk on average 22 grams of ethanol less than controls and were significantly more likely to be adhering to low-risk drinking guidelines at post-treatment (RD 0.13, 95% CI: 0.09–0.17, p<.001). Subgroup analyses revealed no significant differences in potential moderators for the outcome of alcohol consumption, although there was a near-significant difference between comparisons with waitlist control and those with assessment-only or alcohol information control conditions (p = .056). Conclusions Internet interventions are effective in reducing adult alcohol consumption and inducing alcohol users to adhere to guidelines for low-risk drinking. This effect is small but from a public health point of view this may warrant large scale implementation at low cost of Internet interventions for adult alcohol misuse. Moderator analyses with sufficient power are, however, needed in order to assess the robustness of these overall results and to

    Surgical smoke is the gaseous by-product formed during surgical procedures. Most surgeons, operating theatre staff and administrators are unaware of its potential health risks. Surgical smoke is produced by various surgical instruments including those used in electrocautery, lasers, ultrasonic scalpels, high speed drills, burrs and saws. The potential risks include carbon monoxide toxicity to the patient undergoing a laparoscopic operation, pulmonary fibrosis induced by non-viable particles, and transmission of infectious diseases like human papilloma virus. Cytotoxicity and mutagenicity are other concerns. Minimisation of the production of surgical smoke and modification of any evacuation systems are possible solutions. In general, a surgical mask can provide more than 90% protection to exposure to surgical smoke; however, in most circumstances it cannot provide air-tight protection to the user. An at least N95 grade or equivalent respirator offers the best protection against surgical smoke, but whether such protection is necessary is currently unknown. PMID:19892630

    The aim of this study was to examine the acute effects of mental work and moderate-intensity physical activity on various components of energy balance in young and healthy adults. With the use of a randomized crossover design, 35 participants aged 24 ± 3 years completed three 45-min conditions, namely, (i) resting in a sitting position (control), (ii) reading and writing (mental work (MW)), and (iii) exercising on a treadmill at 40% of peak oxygen uptake (exercise), followed by an ad libitum lunch. The endpoints were spontaneous energy intake (EI), energy expenditure (EE), appetite sensations, and EI for the remainder of the day. We observed that the energy cost of the control and MW conditions was about the same whereas the exercise condition increased EE to a greater extent in men than women. Exercise induced a decrease in EI relative to EE compared to the control condition that was more pronounced in men than women. However, women tended to increase their energy intake after the MW condition compared to the control one whereas an opposite trend was observed in men. None of the appetite sensation markers differed significantly between both sexes. In conclusion, men and women have specific food intake patterns when submitted to cognitive and physical stimuli.

    Interventional studies suggest that changes in physical fitness affect brain function and structure. We studied the influence of high intensity physical exercise on hippocampal volume and metabolism in 17 young healthy male adults during a 6-week exercise program compared with matched controls. We further aimed to relate these changes to hypothesized changes in exercised-induced brain-derived neurotrophic factor (BDNF), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α). We show profound improvement of physical fitness in most subjects and a positive correlation between the degree of fitness improvement and increased BDNF levels. We unexpectedly observed an average volume decrease of about 2%, which was restricted to right hippocampal subfields CA2/3, subiculum, and dentate gyrus and which correlated with fitness improvement and increased BDNF levels negatively. This result indicates that mainly those subjects who did not benefit from the exercise program show decreased hippocampal volume, reduced BDNF levels, and increased TNF-α concentrations. While spectroscopy results do not indicate any neuronal loss (unchanged N-acetylaspartate levels) decreased glutamate-glutamine levels were observed in the right anterior hippocampus in the exercise group only. Responder characteristics need to be studied in more detail. Our results point to an important role of the inflammatory response after exercise on changes in hippocampal structure. PMID:26082010

    We studied the impact of Plasmodium falciparum on nutritional status in a longitudinal cohort of 147 young men in western Kenya, where malaria transmission is intense and perennial. All volunteers received treatment to eradicate parasitemia and then provided weekly blood smears during a 16-week transmission season. We measured body mass index (BMI), pubertal development, frequency and density of parasitemia, and tumor necrosis factor (TNF)-alpha production by peripheral blood mononuclear cells. During early puberty, mean parasite density had a strong negative effect on the natural increase in BMI. Among older individuals, TNF-alpha production in response to malarial antigen predicted a significantly lower BMI (P<.03), equal to 4.6 kg for a man of average height. Our data indicate that burden of parasitemia has a detrimental effect on the nutritional status of early adolescents and that malaria may continue to influence nutritional status among older adolescents and adults via host elaboration of proinflammatory cytokines. These effects of malaria may have pervasive health and socioeconomic consequences in areas where malaria is endemic.

    Background: In critically ill patients, several scoring systems have been developed over the last three decades. The Acute Physiology and Chronic Health Evaluation (APACHE) and the Simplified Acute Physiology Score (SAPS) are the most widely used scoring systems in the intensive care unit (ICU). The aim of this study was to assess the prognostic accuracy of SAPS II and APACHE II and APACHE III scoring systems in predicting short-term hospital mortality of surgical ICU patients. Materials and Methods: Prospectively collected data from 202 patients admitted to Mashhad University Hospital postoperative ICU were analyzed. Calibration was estimated using the Hosmer-Lemeshow goodness-of-fit test. Discrimination was evaluated by using the receiver operating characteristic (ROC) curves and area under a ROC curve (AUC). Result: Two hundred and two patients admitted on post-surgical ICU were evaluated. The mean SAPS II, APACHE II, and APACHE III scores for survivors were found to be significantly lower than of non-survivors. The calibration was best for APACHE II score. Discrimination was excellent for APACHE II (AUC: 0.828) score and acceptable for APACHE III (AUC: 0.782) and SAPS II (AUC: 0.778) scores. Conclusion: APACHE II provided better discrimination than APACHE III and SAPS II calibration was good at APACHE II and poor at APACHE III and SAPS II. Use of APACHE II was excellent in this post-surgical ICU. PMID:24791049

    The aim was to analyze the associations between high-intensity and long-lasting weight-bearing sports with hip structure in young adults. One hundred and seventy-two subjects aged 17-28 yr were divided into 4 groups: 40 athlete women (10.2 ± 2.2 h/wk), 30 control women, 67 athlete men (11.4 ± 3.6 h/wk), and 35 control men. The nondominant femur, lumbar spine, and whole body were scanned by dual-energy X-ray absorptiometry to assess bone mineral content (BMC) and bone mineral density (BMD). Hip structure analysis (HSA) software was applied to evaluate cross-sectional area, cross-sectional moment of inertia, and section modulus at the femoral neck, intertrochanter, and femoral shaft regions. All the BMC and BMD values were significantly higher in athletes of both sexes compared with controls (p < 0.05). Most of the hip structural parameters were significantly higher (p < 0.05) in athletes compared with controls. Most of the differences were maintained after adjustments for height, weight, and calcium intake. Positively significant correlations were observed between HSA parameters and physical activity variables in both sexes (r > 0.32; p < 0.05). Partial correlation suggested that the hours of practice appeared to have a greater influence than the years of practice on hip bone geometry. These results suggest that external mechanical loading is a strong determinant of hip bone structure when weight-bearing physical activity is commenced before puberty and maintained during adulthood.

    Lifestyle interventions have resulted in weight loss or improved physical fitness among individuals with obesity, which may lead to improved physical function. This prospective investigation involved participants in the Action for Health in Diabetes (Look AHEAD) trial who reported knee pain at baseline (n = 2,203). The purposes of this investigation were to determine whether an Intensive Lifestyle Intervention (ILI) condition resulted in improvement in self-reported physical function from baseline to 12 months vs. a Diabetes Support and Education (DSE) condition, and whether changes in weight or fitness mediated the effect of the ILI. Outcome measures included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain, stiffness, and physical function subscales, and WOMAC summary score. ILI participants exhibited greater adjusted mean weight loss (s.e.) vs. DSE participants (-9.02 kg (0.48) vs. -0.78 kg (0.49); P < 0.001)). ILI participants also demonstrated more favorable change in WOMAC summary scores vs. DSE participants (β (s.e.) = -1.81 (0.63); P = 0.004). Multiple regression mediation analyses revealed that weight loss was a mediator of the effect of the ILI intervention on change in WOMAC pain, function, and summary scores (P < 0.001). In separate analyses, increased fitness also mediated the effect of the ILI intervention upon WOMAC summary score (P < 0.001). The ILI condition resulted in significant improvement in physical function among overweight and obese adults with diabetes and knee pain. The ILI condition also resulted in significant weight loss and improved fitness, which are possible mechanisms through which the ILI condition improved physical function.

    The population health effect and cost-effectiveness of implementing intensive blood pressure goals in high-cardiovascular disease (CVD) risk adults have not been described. Using the CVD Policy Model, CVD events, treatment costs, quality-adjusted life years, and drug and monitoring costs were simulated over 2016 to 2026 for hypertensive patients aged 35 to 74 years. We projected the effectiveness and costs of hypertension treatment according to the 2003 Joint National Committee (JNC)-7 or 2014 JNC8 guidelines, and then for adults aged ≥50 years, we assessed the cost-effectiveness of adding an intensive goal of systolic blood pressure <120 mm Hg for patients with CVD, chronic kidney disease, or 10-year CVD risk ≥15%. Incremental cost-effectiveness ratios <$50 000 per quality-adjusted life years gained were considered cost-effective. JNC7 strategies treat more patients and are more costly to implement compared with JNC8 strategies. Adding intensive systolic blood pressure goals for high-risk patients prevents an estimated 43 000 and 35 000 annual CVD events incremental to JNC8 and JNC7, respectively. Intensive strategies save costs in men and are cost-effective in women compared with JNC8 alone. At a willingness-to-pay threshold of $50 000 per quality-adjusted life years gained, JNC8+intensive had the highest probability of cost-effectiveness in women (82%) and JNC7+intensive the highest probability of cost-effectiveness in men (100%). Assuming higher drug and monitoring costs, adding intensive goals for high-risk patients remained consistently cost-effective in men, but not always in women. Among patients aged 35 to 74 years, adding intensive blood pressure goals for high-risk groups to current national hypertension treatment guidelines prevents additional CVD deaths while saving costs provided that medication costs are controlled.

    Close to 3% of all intubation attempts are considered difficult airways, for which a plan for a surgical airway should be considered. Our article provides an overview of the different types of surgical airways. This article provides a comprehensive review of the main types of surgical airways, relevant anatomy, necessary equipment, indications and contraindications, preparation and positioning, technique, complications, and tips for management. It is important to remember that the placement of a surgical airway is a lifesaving procedure and should be considered in any setting when one “cannot intubate, cannot ventilate”. PMID:24741501

    Temporomandibular joint ankylosis (TMJA) is a severe disorder described as an intracapsular union of the disc-condyle complex to the temporal articular surface with bony fusion. The management of this disability is challenging and rarely based on surgical and rehabilitation protocols. We describe the treatment in two young adults affected by Goldenhar syndrome and Pierre Robin sequence with reankylosis after previous surgical treatments. There are three main surgical procedures for the treatment of TMJA: gap arthroplasty, interpositional arthroplasty, and joint reconstruction. Various authors have described reankylosis as a frequent event after treatment. Treatment failure could be associated with surgical errors and/or inadequate intensive postoperative physiotherapy. Surgical treatment should be individually tailored and adequate postoperative physiotherapy protocol is mandatory for success. PMID:24624260

    Late-life depression and pain more often co-occur than can be explained by chance. Determinants of pain in late-life depression are unknown, even though knowledge on possible determinants of pain in depression is important for clinical practice. Therefore, the objectives of the present study were 1) to describe pain characteristics of depressed older adults and a nondepressed comparison group, and 2) to explore physical, lifestyle, psychological, and social determinants of acute and chronic pain intensity, disability, and multisite pain in depressed older adults. Data from the Netherlands Study of Depression in Older Persons cohort, consisting of 378 depressed persons, diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, 4th edition criteria, and 132 nondepressed persons aged 60 years and older, were used in a cross-sectional design. Pain characteristics were measured by the Chronic Graded Pain Scale. Multiple linear regression analyses were performed to explore the contribution of physical, lifestyle, psychological, and social determinants to outcomes pain intensity, disability, and the number of pain locations. Depressed older adults more often reported chronic pain and experienced their pain as more intense and disabling compared to nondepressed older adults. Adjusted for demographic, physical, and lifestyle characteristics, multinomial logistic regression analyses showed increased odds ratios (OR) for depression in acute pain (OR 3.010; P=0.005) and chronic pain (OR 4.544, P<0.001). In addition, linear regression analyses showed that acute and chronic pain intensity, disability, and multisite pain were associated with several biopsychosocial determinants, of which anxiety was most pronounced. Further research could focus on the temporal relationship between anxiety, late-life depression, and pain.

    Acute renal failure (ARF) in critically ill patients is currently very frequent and requires renal replacement therapy (RRT) in many patients. During the last 15 years, several studies have considered important issues regarding the use of RRT in ARF, like the time to initiate the therapy, the dialysis dose, the types of catheter, the choice of technique, and anticoagulation. However, despite an abundant literature, conflicting results do not provide evidence on RRT implementation. We present herein recommendations for the use of RRT in adult and pediatric intensive care developed with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system by an expert group of French Intensive Care Society (SRLF), with the participation of the French Society of Anesthesia and Intensive Care (SFAR), the French Group for Pediatric Intensive Care and Emergencies (GFRUP), and the French Dialysis Society (SFD). The recommendations cover 4 fields: criteria for RRT initiation, technical aspects (access routes, membranes, anticoagulation, reverse osmosis water), practical aspects (choice of the method, peritoneal dialysis, dialysis dose, adjustments), and safety (procedures and training, dialysis catheter management, extracorporeal circuit set-up). These recommendations have been designed on a practical point of view to provide guidance for intensivists in their daily practice. PMID:26714808

    Exercise training at a variety of intensities increases maximal oxygen uptake (VO2max), the strongest predictor of cardiovascular and all-cause mortality. The purpose of the present study was to perform a systematic review, meta-regression and meta-analysis of available literature to determine if a dose-response relationship exists between exercise intensity and training-induced increases in VO2max in young healthy adults. Twenty-eight studies involving human participants (Mean age: 23±1 yr; Mean VO2max: 3.4±0.8 l·min−1) were included in the meta-regression with exercise training intensity, session dose, baseline VO2max, and total training volume used as covariates. These studies were also divided into 3 tertiles based on intensity (tertile 1: ~60–70%; 2: ~80–92.5%; 3: ~100–250%VO2max), for comparison using separate meta-analyses. The fixed and random effects meta-regression models examining training intensity, session dose, baseline VO2max and total training volume was non-significant (Q4=1.36; p=0.85; R2=0.05). There was no significant difference between tertiles in mean change in VO2max (tertile 1:+0.29±0.15 l/min, ES (effect size) =0.77; 2:+0.26±0.10 l/min, ES=0.68; 3:+0.35±0.17 l/min, ES=0.80), despite significant (p<0.05) reductions in session dose and total training volume as training intensity increased. These data suggest that exercise training intensity has no effect on the magnitude of training-induced increases in maximal oxygen uptake in young healthy human participants, but similar adaptations can be achieved in low training doses at higher exercise intensities than higher training doses of lower intensity (endurance training).

    The objective of this study was to describe a hospital cluster of NDM-1-producing Enterobacter cloacae infections observed in the surgical intensive care unit (ICU) of a tertiary-care hospital at Pula, Croatia. NDM-1-producing E. cloacae strains isolated from clinical samples were screened by PCR for the presence of carbapenemases. Genetic relatedness of NDM-1-producing E. cloacae strains was determined by multilocus sequence typing (MLST). During the period October 2013 to April 2014, four patients, with overlapping hospital stay in the surgical ICU, developed severe infections caused by E. cloacae demonstrated to produce carbapenemases. According to MLST, all strains belonged to ST133 and were positive by PCR for the blaNDM-1 carbapenemase gene, for blaCTX-M-15 and blaSHV-12 extended-spectrum β-lactamase (ESBL) genes, and for blaTEM-1 and blaOXA-1 narrow-spectrum β-lactamase genes. They were negative for other carbapenemases genes including blaOXA-48, blaVIM and blaKPC as well as for AmpC and the armA and rmtB aminoglycoside resistance genes. All strains were positive for the HI2 replicon, suggesting that an IncHI2 plasmid is likely the plasmid carrying the blaNDM-1 gene. Infection control measures were implemented after the first case although they were not effective in avoiding spread of this organism to other patients in the surgical ICU. In conclusion, the evolving epidemiology of NDM-producing micro-organisms and the interspecies diffusion of this resistance mechanism to emerging pathogens such as E. cloacae necessitate the setting up of strong and urgent joint measures to control the spread of NDM carbapenemase especially in the ICU setting.

    Obstructive sleep disordered breathing can cause death and significant morbidity in adults and children. We previously found that children with smaller upper airways (measured by magnetic resonance imaging while awake) generated loud high frequency inspiratory sounds (HFIS, defined as inspiratory sounds > 2 kHz) while they slept. The purpose of this study was (1) to determine what characteristics of airflow predicted HFIS intensity, and (b) to determine if we could calculate changes in hydraulic diameter (D) in both an in vitro model and in the upper airways of sleeping humans. In an in vitro model, high frequency sound intensity was an estimate of airflow turbulence as reflected by the Reynold's number (Re). D of the in vitro model was calculated using Re, the pressure gradient, Swamee–Jain formula and Darcy formula. D was proportional to but smaller than the actual diameters (r2 = 0.94). In humans, we measured HFIS intensity and the pressure gradient across the upper airway (estimated with oesophageal pressure, Pes) during polysomnography in four adult volunteers and applied the same formulae to calculate D. At apnoea termination when the airway opens, we observed (1) an increase in HFIS intensity suggesting an increase in turbulence (higher Re), and (2) a larger calculated D. This method allows dynamic estimation of changes in relative upper airway hydraulic diameter (D) in sleeping humans with narrowed upper airways. PMID:24973405

This kind of treatment was conducted with simultaneous intensive preoperative preparation, surgical intervention consisted of open thoracotomy with thoracic duct suturing and ligature. The operative treatment had appeared primarily ultimately successful in 5 (62.5%) patients, and after postoperative pleurodesis conduction--in 3 (37.5%). One week of intensive conservative therapy trial with simultaneous preoperative preparation and subsequent shift to surgical intervention constitutes an optimal tactical principle in the persisting chylothorax treatment.

    Introduction Most data on de-escalation of empirical antimicrobial therapy has focused on ventilator-associated pneumonia. In this retrospective monocentric study, we evaluated de-escalation as part of a global strategy of empiric antibiotherapy management irrespective of the location and the severity of the infection. The goal of this trial was to assess the application of a de-escalation strategy and the impact in terms of re-escalation, recurrent infection and to identify variables associated with de-escalation. Methods All consecutive patients treated with empiric antibiotic therapy and hospitalized in the intensive care unit for at least 72 hours within a period of 16 months were included. We compared the characteristics and outcome of patients who have experienced de-escalation therapy with those who have not. Results A total of 116 patients were studied corresponding to 133 infections. Antibiotic therapy was de-escalated in 60 cases (45%). De-escalation, primarily accomplished by a reduction in the number of antibiotics used, was observed in 52% of severe sepsis or septic shock patients. Adequate empiric antibiotic and use of aminoglycoside were independently linked with de-escalation. De-escalation therapy was associated with a significant reduction of recurrent infection (19% vs 5% P = 0.01). Mortality was not changed by de-escalation. Conclusions As part of a global management of empiric antibiotherapy in an intensive care unit, de-escalation might be safe and feasible in a large proportion of patients. PMID:21167047

    The REDUCE MRSA Trial (Randomized Evaluation of Decolonization vs Universal Clearance to Eliminate Methicillin-Resistant Staphylococcus aureus), a large multicenter, randomized controlled trial in adult intensive care units (ICUs), found universal decolonization to be more effective than surveillance and isolation procedures with or without targeted decolonization for reducing rates of MRSA-positive clinical cultures. The Agency for Healthcare Research and Quality and the Centers for Disease Control and Prevention subsequently published protocols for implementing universal decolonization in ICUs based on the trial's methods. Caution should be exercised before widely adopting these procedures in neonatal intensive care units (NICUs), particularly strategies that involve bathing with chlorhexidine and mupirocin application due to the potential for adverse events in their unique patient population, especially preterm infants. Large multicenter trials in the NICUs are needed to evaluate the efficacy, short- and long-term safety, and cost effectiveness of these strategies prior to their widespread implementation.

    As the population ages, research into the assessment of postoperative pain in older patients is urgently needed. The reliability and validity of most pain scales for the assessment of acute postoperative pain in the elderly remain to be demonstrated. The present study reports the analysis of age-related patterns on three pain scales (McGill Pain Questionnaire, MPQ; Present Pain Intensity, PPI; and Visual Analog Scale, VAS) completed by younger (n=95, mean age=56.4+/-5.8 years) and older (n=105; mean age=66.8+/-2.7 years) men following radical prostatectomy. All patients received intravenous morphine via patient-controlled analgesia (PCA) throughout the study. On the first 2 postoperative days (POD), patients completed the pain scales and PCA opioid intake was recorded. An interaction was found between amount of opioid self-administered and POD. In both groups, less opioid was administered on POD 2 than POD 1, but the decrease over time was greater in younger than older men. On both PODs, older men self-administered less opioid than younger men. Age differences in pain were dependent on the pain scale used. Older men had significantly lower scores than younger men on the MPQ and PPI but there were no differences on the VAS. Several age differences in the psychometric properties of the scales were evident. On both PODs, the correlation between VAS and MPQ scores was significantly lower in the older than younger group. POD effect sizes did not differ between the scales or age groups suggesting that all three scales have comparable sensitivity within an age group. However, the different results between the scales for the effect of age suggests that the VAS is not sufficiently sensitive to detect age differences. Therefore, age differences in postoperative pain are better captured by verbal descriptions of pain qualities than non-verbal measures of intensity.

    Aging is associated with decreased aerobic fitness and cardiac remodeling leading to increased risk for cardiovascular disease. High-intensity interval training (HIIT) on the treadmill has been reported to be more effective in ameliorating these risk factors compared with moderate-intensity continuous training (MICT) in patients with cardiometabolic disease. In older adults, however, weight-bearing activities are frequently limited due to musculoskeletal and balance problems. The purpose of this study was to examine the feasibility and safety of non-weight-bearing all-extremity HIIT in older adults. In addition, we tested the hypothesis that all-extremity HIIT will be more effective in improving aerobic fitness, cardiac function, and metabolic risk factors compared with all-extremity MICT. Fifty-one healthy sedentary older adults (age: 65±1years) were randomized to HIIT (n=17), MICT (n=18) or non-exercise control (CONT; n=16). HIIT (4×4min 90% of peak heart rate; HRpeak) and isocaloric MICT (70% of HRpeak) were performed on a non-weight-bearing all-extremity ergometer, 4×/week for 8weeks under supervision. All-extremity HIIT was feasible in older adults and resulted in no adverse events. Aerobic fitness (peak oxygen consumption; VO2peak) and ejection fraction (echocardiography) improved by 11% (P<0.0001) and 4% (P=0.001), respectively in HIIT, while no changes were observed in MICT and CONT (P≥0.1). Greater improvements in ejection fraction were associated with greater improvements in VO2peak (r=0.57; P<0.0001). Insulin resistance (homeostatic model assessment) decreased only in HIIT by 26% (P=0.016). Diastolic function, body composition, glucose and lipids were unaffected (P≥0.1). In conclusion, all-extremity HIIT is feasible and safe in older adults. HIIT, but not MICT, improved aerobic fitness, ejection fraction, and insulin resistance. PMID:27346646

    Colonization with Candida species is an independent risk factor for invasive candidiasis (IC), but the minimum and most practicable parameters for prediction of IC have not been optimized. We evaluated Candida colonization in a prospective cohort of 6,015 nonneutropenic, critically ill patients. Throat, perineum, and urine were sampled 72 h post-intensive care unit (ICU) admission and twice weekly until discharge or death. Specimens were cultured onto chromogenic agar, and a subset underwent molecular characterization. Sixty-three (86%) patients who developed IC were colonized prior to infection; 61 (97%) tested positive within the first two time points. The median time from colonization to IC was 7 days (range, 0 to 35). Colonization at any site was predictive of IC, with the risk of infection highest for urine colonization (relative risk [RR] = 2.25) but with the sensitivity highest (98%) for throat and/or perineum colonization. Colonization of ≥2 sites and heavy colonization of ≥1 site were significant independent risk factors for IC (RR = 2.25 and RR = 3.7, respectively), increasing specificity to 71% to 74% but decreasing sensitivity to 48% to 58%. Molecular testing would have prompted a resistance-driven decision to switch from fluconazole treatment in only 11% of patients infected with C. glabrata, based upon species-level identification alone. Positive predictive values (PPVs) were low (2% to 4%) and negative predictive values (NPVs) high (99% to 100%) regardless of which parameters were applied. In the Australian ICU setting, culture of throat and perineum within the first two time points after ICU admission captures 84% (61/73 patients) of subsequent IC cases. These optimized parameters, in combination with clinical risk factors, should strengthen development of a setting-specific risk-predictive model for IC. PMID:25673797

  11. Drought reduces chytrid fungus (Batrachochytrium dendrobatidis) infection intensity and mortality but not prevalence in adult crawfish frogs (Lithobates areolatus).

    To fully understand the impacts of the chytrid fungus Batrachochytrium dendrobatidis (Bd) on amphibians it is necessary to examine the interactions between populations and their environment. Ecologic variables can exacerbate or ameliorate Bd prevalence and infection intensity, factors that are positively related when Bd is acting on naive amphibian populations as an epidemic disease. In crawfish frogs (Lithobates areolatus), a North American species with a complex life history, we have shown that Bd acts as an endemic disease with impacts that vary seasonally; the highest infection prevalences and intensities and highest frog mortality occurred during late spring in postbreeding individuals. In this study, conducted between 28 February and 23 August 2011 in southwestern Indiana on the same population, we report an uncoupling of the previously observed relationship between Bd prevalence and intensity following an extreme drought. Specifically, there was a postdrought reduction in Bd infection intensity and mortality, but not in infection prevalence. This result suggests that the relationship between prevalence and intensity observed in Bd epidemics can be uncoupled in populations harboring endemic infections. Further, constant prevalence rates suggest either that crawfish frogs are being exposed to Bd sources independent of ambient moisture or that low-level infections below detection thresholds persist from year to year. Drought has several ecologically beneficial effects for amphibians with complex life histories, including eliminating fish and invertebrate populations that feed on larvae. To these ecologic benefits we suggest another, that drought can reduce the incidence of the severe skin disease (chytridiomycosis) due to Bd infection.

    This study examined the ways in which individuals over 50 years old solved problems while volunteering in intensive humanitarian and disaster relief service. Thirty-seven men and women in the sample were sponsored by three religious organizations well known for providing humanitarian and disaster relief service. Semistructured interviews yielded data that were analyzed qualitatively, using McCracken's five-step process for analysis. We found that volunteers used three different abilities to solve problems: drawing upon experience to create strategies, maintaining emotional stability in the midst of trying circumstances, and applying strategies in a context-sensitive manner. These findings illustrate that these factors, which are comparable to those used in solving everyday problems, are unique in the way they are applied to intensive volunteering. The volunteers' sharing of knowledge, experience, and support with each other were also noticeable in their accounts of their service. This sharing contributed strongly to their sense of emotional stability and effectiveness in solving problems.

    Multi-family therapy (MFT) has yet to be evaluated in families of adults with anorexia nervosa (AN). The study aims were: (i) assess the feasibility of MFT for AN; and, (ii) assess whether MFT is associated with improved outcomes for families compared with single-family therapy (SFT). Adult patients with AN consecutively referred to an eating disorder treatment program were assigned (non-randomly) to receive eight sessions of SFT or MFT. Assessment occurred pre-therapy, immediately post-therapy, and at 3-month follow-up. A total of 37 female patients (13 SFT, 24 MFT) and 45 family members (16 SFT, 29 MFT) completed treatment. There were significant time effects for patients' BMI, eating disorder-related psychopathology and multiple family outcome measures. There were no differences between MFT and SFT on family outcome measures at end of treatment and 3 months post treatment. MFT is a feasible intervention that can be used in adult intensive treatment for those with AN. PMID:25823423

    Despite the popularity of video games, few studies have been conducted in France on their use. The objective of this study was to gather data from a sample of French video game players to learn more about this population. This approach also aimed to examine whether differences exist between adolescent and adult gamers in terms of their motivations to play and whether this practice met the criteria for problem video game playing. A questionnaire collecting sociodemographic data and assessing the problems associated with the use of video games, as well as motivations to play, was distributed during a video game festival and on the Internet. A total of 778 people responded to the questionnaire. The results showed that there were few differences between adolescent and adult gamers. Both groups had an intense video game habit. The majority of them sometimes had the feeling of losing control of their use and sacrificed other activities to play video games. This last dimension was most frequently cited by adults. The feeling of spending more time playing was most frequently cited by adolescents. Concerning motivations to play, the two groups differed only on the score of the "social" dimension, significantly higher among adolescents.

    In 2006, Critical Care Nursing Quarterly published a study of the physical design features of a set of best practice example adult intensive care units (ICUs). These adult ICUs were awarded between 1993 and 2003 by the Society of Critical Care Medicine (SCCM), the American Association of Critical-Care Nurses, and the American Institute of Architects/Academy of Architecture for Health for their efforts to promote the critical care unit environment through design. Since 2003, several more adult ICUs were awarded by the same organizations for similar efforts. This study includes these newer ICUs along with those of the previous study to cover a period of 2 decades from 1993 to 2012. Like the 2006 study, this study conducts a systematic content analysis of the materials submitted by the award-winning adult ICUs. On the basis of the analysis, the study compares the 1993-2002 and 2003-2012 adult ICUs in relation to construction type, unit specialty, unit layout, unit size, patient room size and design, support and service area layout, and family space design. The study also compares its findings with the 2010 Guidelines for Design and Construction of Health Care Facilities of the Facility Guidelines Institute and the 2012 Guidelines for Intensive Care Unit Design of the SCCM. The study indicates that the award-winning ICUs of both decades used several design features that were associated with positive outcomes in research studies. The study also indicates that the award-winning ICUs of the second decade used more evidence-based design features than those of the first decades. In most cases, these ICUs exceeded the requirements of the Facility Guidelines Institute Guidelines to meet those of the SCCM Guidelines. Yet, the award-winning ICUs of both decades also used several features that had very little or no supporting research evidence. Since they all were able to create an optimal critical care environment for which they were awarded, having knowledge of the physical

    Our six-week treadmill running training (forced exercise) model has revealed that mild exercise (ME) with an intensity below the lactate threshold (LT) is sufficient to enhance spatial memory, while intense exercise (IE) above the LT negates such benefits. To help understand the unrevealed neuronal and signaling/molecular mechanisms of the intensity-dependent cognitive change, in this rat model, we here investigated plasma corticosterone concentration as a marker of stress, adult hippocampal neurogenesis (AHN) as a potential contributor to this ME-induced spatial memory, and comprehensively delineated the hippocampal transcriptomic profile using a whole-genome DNA microarray analysis approach through comparison with IE. Results showed that only IE had the higher corticosterone concentration than control, and that the less intense exercise (ME) is better suited to improve AHN, especially in regards to the survival and maturation of newborn neurons. DNA microarray analysis using a 4 × 44 K Agilent chip revealed that ME regulated more genes than did IE (ME: 604 genes, IE: 415 genes), and only 41 genes were modified with both exercise intensities. The identified molecular components did not comprise well-known factors related to exercise-induced AHN, such as brain-derived neurotrophic factor. Rather, network analysis of the data using Ingenuity Pathway Analysis algorithms revealed that the ME-influenced genes were principally related to lipid metabolism, protein synthesis and inflammatory response, which are recognized as associated with AHN. In contrast, IE-influenced genes linked to excessive inflammatory immune response, which is a negative regulator of hippocampal neuroadaptation, were identified. Collectively, these results in a treadmill running model demonstrate that long-term ME, but not of IE, with minimizing running stress, has beneficial effects on increasing AHN, and provides an ME-specific gene inventory containing some potential regulators of this

    Aging is associated with a functional decline of the oxidative metabolism due to progressive limitations of both O(2) delivery and utilization. Priming exercise (PE) increases the speed of adjustment of oxidative metabolism during successive moderate-intensity transitions. We tested the hypothesis that such improvement is due to a better matching of O(2) delivery to utilization within the working muscles. In 21 healthy older adults (65.7 ± 5 yr), we measured contemporaneously noninvasive indexes of the overall speed of adjustment of the oxidative metabolism (i.e., pulmonary Vo(2) kinetics), of the bulk O(2) delivery (i.e., cardiac output), and of the rate of muscle deoxygenation (i.e., deoxygenated hemoglobin, HHb) during moderate-intensity step transitions, either with (ModB) or without (ModA) prior PE. The local matching of O(2) delivery to utilization was evaluated by the ΔHHb/ΔVo(2) ratio index. The overall speed of adjustment of the Vo(2) kinetics was significantly increased in ModB compared with ModA (P < 0.05). On the contrary, the kinetics of cardiac output was unaffected by PE. At the muscle level, ModB was associated with a significant reduction of the "overshoot" in the ΔHHb/ΔVo(2) ratio compared with ModA (P < 0.05), suggesting an improved O(2) delivery. Our data are compatible with the hypothesis that, in older adults, PE, prior to moderate-intensity exercise, beneficially affects the speed of adjustment of oxidative metabolism due to an acute improvement of the local matching of O(2) delivery to utilization.

    The skin cannot be sterilized because approximately 20% of the resident flora are beyond the reach of surgical scrubs and antiseptics. The goal of surgical preparation of the skin with antiseptics is to remove transient and pathogenic microorganisms on the skin surface and to reduce the resident flora to a low level. Four antiseptics which have been popular over the past two decades are discussed. Benzalkonium chloride is somewhat unstable on the skin and is too prone to contamination to be in general use. Hexachlorophene is not recommended due to narrow spectrum and risks secondary to percutaneous absorption. The iodophors are excellent antiseptics, but recent studies raise questions about effectiveness and contamination. Chlorhexidine is a very safe and effective antiseptic. Comparison studies with chlorhexidine, hexachlorophene, and iodophors show chlorhexidine to be the most effective agent. Chlorhexidine can be toxic to the middle ear and irritating to the eyes with direct contact. Caution should be used in these areas with chlorhexidine and other antiseptics.

    Evaluation of the patient's medical history and a physical examination are the cornerstones of risk assessment prior to elective surgery and may help to optimize the patient's preoperative medical condition and to guide perioperative management. Whether the performance of additional technical tests (e.g. blood chemistry, ECG, spirometry, chest-x-ray) can contribute to a reduction of perioperative risk is often not very well known or controversial. Similarly, there is considerable uncertainty among anesthesiologists, internists and surgeons with respect to the perioperative management of the patient's long-term medication. Therefore, the German Scientific Societies of Anesthesiology and Intensive Care Medicine (DGAI), Internal Medicine (DGIM) and Surgery (DGCH) have joined to elaborate and publish recommendations on the preoperative evaluation of adult patients prior to elective, non-cardiac and non-lung resection surgery. In the first part the general principles of preoperative evaluation are described (part A). The current concepts for extended evaluation of patients with known or suspected major cardiovascular disease are presented in part B. Finally, the perioperative management of patients' long-term medication is discussed (part C). The concepts proposed in these interdisciplinary recommendations endorsed by the DGAI, DGIM and DGCH provide a common basis for a structured preoperative risk assessment and management. These recommendations aim to ensure that surgical patients undergo a rational preoperative assessment and at the same time to avoid unnecessary, costly and potentially dangerous testing. The joint recommendations reflect the current state-of-the-art knowledge as well as expert opinions because scientific-based evidence is not always available. These recommendations will be subject to regular re-evaluation and updating when new validated evidence becomes available.

This study translates such implicit or procedural knowledge into explicit or declarative knowledge, with a view to improving both training and retraining of surgeons in the steps of dissection. Tools used include ordinary observation accompanied by introspection, and study of operative videos. Validation of the value of such heuristics is yet to be achieved.

    Breast surgical oncology is a defined sub-specialty of general surgery with focus on the surgical management of breast disease and malignancy within a multidisciplinary context. Much of the training of breast surgical oncologists in the United States exists within a fellowship training structure with oversight and approval by the Society of Surgical Oncology (SSO). Rapid continuous changes in breast oncology practice have further substantiated dedicated expertise in breast surgical oncology. Training programs are structured to develop proficiency in fellows for advanced surgical techniques and clinical decision-making as well as exposure to the multidisciplinary aspects of breast cancer management. Components of a successful program include an intense multidisciplinary curriculum, engagement in clinical research and attention to strong mentorship. National curriculum and training requirements as well as supplemental resources assist in standardizing the fellowship experience. As surgical training and the field of breast oncology continues to evolve, so do fellowship training programs to ensure high quality breast surgical oncologists equipped to deliver high quality evidence based patient care while continuing to drive future research and trainee education.

    Although aquatic exercise is considered a potentially effective treatment intervention for people with osteoarthritis (OA), previous research has focused primarily on calisthenics in a shallow pool with the inherent limitations on regulating exercise intensity. The purpose of this study was to quantify the efficacy of a 6-week aquatic treadmill exercise program on measures of pain, balance, function, and mobility. Eighteen participants (age = 64.5 ± 10.2 years) with knee OA completed a non-exercise control period followed by a 6-week exercise period. Outcome measures included visual analog scales for pain, posturography for balance, sit-to-stand test for function, and a 10-m walk test for mobility. The exercise protocol included balance training and high-intensity interval training (HIT) in an aquatic treadmill using water jets to destabilize while standing and achieve high ratings of perceived exertion (14-19) while walking. In comparison with pretests, participants displayed reduced joint pain (pre = 50.3 ± 24.8 mm vs. post = 15.8 ± 10.6 mm), improved balance (equilibrium pre = 66.6 ± 11.0 vs. post = 73.5 ± 7.1), function (rising index pre = 0.49 ± 0.19% vs. post = 0.33 ± 0.11%), and mobility (walk pre = 8.6 ± 1.4 s vs. post = 7.8 ± 1.1 s) after participating in the exercise protocol (p = 0.03-0.001). The same benefits were not observed after the non-exercise control period. Adherence to the exercise protocol was exceptional and no participants reported adverse effects, suggesting that aquatic treadmill exercise that incorporates balance and HIT training was well tolerated by patients with OA and may be effective at managing symptoms of OA.

    2000-01-01

    BACKGROUND: Current guidelines for the management of hypertension recommend regular, moderate intensity aerobic exercise such as brisk walking as a means of blood pressure reduction. However, there is a lack of consistent evidence regarding the magnitude of blood pressure response to such a prescription. In particular, no well designed studies have investigated the efficacy of a programme of exercise meeting current guidelines. AIM: To investigate the effect of a six-week programme of moderate intensity exercise on daytime ambulatory blood pressure (10.00 am to 10.00 pm) among unmedicated, sedentary adults aged 25 years to 63 years with office blood pressure of 150 mmHg to 180 mmHg systolic and/or 91 mmHg to 110 mmHg diastolic. METHOD: Randomised controlled trial of participants carrying out 30 minutes of moderate intensity exercise (brisk walking or equivalent) five days per week for six weeks compared with controls who maintained existing levels of physical activity. RESULTS: Compliance with the exercise programme was high. The reduction in mean daytime ambulatory blood pressure between baseline and six-week follow-up was greater in the intervention group than in the control group for both systolic and diastolic blood pressure. However, this net hypotensive effect was not statistically significant (systolic = -3.4 mmHg, 95% CI = -7.4 to 0.6; diastolic = -2.8 mmHg, 95% CI = -5.8 to 0.2). Adjusting for baseline differences in mean ambulatory blood pressure in an analysis of covariance led to a reduction in the estimated magnitude of the effect (systolic = -1.9 mmHg, 95% CI = -5.4 to 1.7, P = 0.31; diastolic = -2.2 mmHg, 95% CI = -4.9 to 0.5, P = 0.11). CONCLUSION: Despite high compliance with the exercise programme, the magnitude of the hypotensive effect of moderate intensity exercise was not as great as that found in studies of higher intensity exercise among hypertensives. Expectations of general practitioners and patients that a programme of moderate intensity

    The objective of this study was to assess the impact of the exposure duration and intensity on the human kinetic adjustment factor (HKAF). A physiologically based pharmacokinetic model was used to compute target dose metrics (i.e. maximum blood concentration (C(max)) and amount metabolized/L liver/24  h (Amet)) in adults, neonates (0-30 days), toddlers (1-3 years), and pregnant women following inhalation exposure to benzene, styrene, 1,1,1-trichloroethane and 1,4-dioxane. Exposure scenarios simulated involved various concentrations based on the chemical's reference concentration (low) and six of U.S. EPA's Acute Exposure Guideline Levels (AEGLs) (high), for durations of 10  min, 60  min, 8  h, and 24  h, as well as at steady-state. Distributions for body weight (BW), height (H), and hepatic CYP2E1 content were obtained from the literature or from P3M software, whereas blood flows and tissue volumes were calculated from BW and H. The HKAF was computed based on distributions of dose metrics obtained by Monte Carlo simulations [95th percentile in each subpopulation/median in adults]. At low levels of exposure, ranges of C(max)-based HKAF were 1-6.8 depending on the chemical, with 1,4-dioxane exhibiting the greatest values. At high levels of exposure, this range was 1.1-5.2, with styrene exhibiting the greatest value. Neonates were always the most sensitive subpopulation based on C(max), and pregnant women were most sensitive based on Amet in the majority of the cases (1.3-2.1). These results have shown that the chemical-specific HKAF varies as a function of exposure duration and intensity of inhalation exposures, and sometimes exceeds the default value used in risk assessments.

    Background The multi-center cluster-randomized Strategies to Reduce Transmission of Antimicrobial Resistant Bacteria in Intensive Care Units (STAR*ICU) trial was carried out in 18 U.S. adult intensive care units (ICUs) and evaluated the effectiveness of infection control strategies in reducing transmission of methicillin-resistant Staphylococcus aureus (MRSA) colonization and/or infection. Our study objective was to examine the molecular epidemiology of MRSA and assess the prevalence and risk factors for community acquired (CA)-MRSA genotype nasal carriage at the time of ICU admission. Methods Selected MRSA isolates were subjected to molecular typing using pulsed-field gel electrophoresis. Results Among 5,512 ICU patient-admissions in the STAR*ICU trial during the intervention period, 626 (11%) had a positive nares culture for MRSA. 210/626 (34%) available isolates were selected by weighted random sampling for molecular typing. Of 210 patients, 123 (59%) were male; mean age was 63 years. Molecular typing revealed that 147 isolates (70%) were the USA100 clone; 26 (12%) USA300; 12 (6%) USA500; 8 (4%) USA800; 17 (8%) other. In multivariate analysis, patients with CA-MRSA genotype (USA300, USA400, or USA1000) colonization were less likely to have been hospitalized during the previous 12 months (PR=0.39; 95% C.I. 0.21–0.73) and less likely to have an older age (PR=0.97 per year; 0.95–0.98) compared to patients with a HA-MRSA genotype. Conclusion CA-MRSA genotypes have emerged as a cause of MRSA nares colonization among patients admitted to adult ICUs in the U.S. During the study period (2006), the predominant site of CA-MRSA genotype acquisition appeared to be in the community.

Traditional 3D conformal CSI does not spare any critical organs, resulting in toxicity in patients. Here the dosimetric advantages of intensity-modulated radiation therapy (IMRT) and volumetric-modulated arc therapy (VMAT) are compared with classic conformal planning in adults for both cranial and spine fields to develop a clinically feasible technique that is both effective and efficient. Ten adult patients treated with CSI were retrospectively identified. For the cranial fields, 5-field IMRT and dual 356° VMAT arcs were compared with opposed lateral 3D conformal radiotherapy (3D-CRT) fields. For the spine fields, traditional posterior-anterior (PA) PA fields were compared with isocentric 5-field IMRT plans and single 200° VMAT arcs. Two adult patients have been treated using this IMRT technique to date and extensive quality assurance, especially for the junction regions, was performed. For the cranial fields, the IMRT technique had the highest planned target volume (PTV) maximum and was the least efficient, whereas the VMAT technique provided the greatest parotid sparing with better efficiency. 3D-CRT provided the most efficient delivery but with the highest parotid dose. For the spine fields, VMAT provided the best PTV coverage but had the highest mean dose to all organs at risk (OAR). 3D-CRT had the highest PTV and OAR maximum doses but was the most efficient. IMRT provides the greatest OAR sparing but the longest delivery time. For those patients with unresectable disease that can benefit from a higher, definitive dose, 3D-CRT–opposed laterals are the most clinically feasible technique for cranial fields and for spine fields. Although inefficient, the IMRT technique is the most clinically feasible because of the increased mean OAR dose with the VMAT technique. Quality assurance of the beams, especially the junction regions, is essential.

    This study aimed to determine the effects of a single high-intensity interval training (HIIT) session on salivary cortisol (SC) levels, physiological responses, and performance in trained boys and men. Twenty-three boys (11.5 ± 0.8 years) and 25 men (29.7 ± 4.6 years) performed HIIT (4 consecutive Wingate Anaerobic Tests). SC in boys and men increased after HIIT from 5.55 ± 3.3 nmol/l to 15.13 ± 9.7 nmol/l (+173%) and from 7.07 ± 4.7 nmol/l to 19.19 ± 12.7 nmol/l (+171%), respectively (p < .01). Pretest SC as well as posttest changes were comparable in both groups (both p < .01). Peak blood lactate concentration was significantly lower in boys (12.6 ± 3.5 mmol/l) than in men (16.3 ± 3.1 mmol/l; p < .01). Throughout the HIIT, mean heart rates in boys were higher (p < .001) but relative peak oxygen uptake (ml·min-1·kg-1; p < .05) and performance were lower (p < .001) in boys than in men. HIIT in young athletes is associated with a higher activation of the hormonal stress axis than other types of exercise regimes as described in the literature. This study is the first to show a pronounced SC increase to HIIT in trained boys accompanied by elevated levels of blood lactate concentrations and heart rate suggesting a high cardio-respiratory, metabolic, and hormonal response to HIIT in 11-year-old boys.

    Background Identifying modifiable determinants of fat mass and muscle strength in older adults is important given their impact on physical functioning and health. Light intensity physical activity and sedentary behavior are potential determinants, but their relations to these outcomes are poorly understood. We evaluated associations of light intensity physical activity and sedentary time—assessed both objectively and by self-report—with body mass index (BMI) and grip strength in a large sample of older adults. Methods We used cross-sectional baseline data from 1130 participants of the Lifestyle Interventions and Independence for Elders (LIFE) study, a community-dwelling sample of relatively sedentary older adults (70-89 years) at heightened risk of mobility disability. Time spent sedentary and in light intensity activity were assessed using an accelerometer worn for 3–7 days (Actigraph GT3X) and by self-report. Associations between these exposures and measured BMI and grip strength were evaluated using linear regression. Results Greater time spent in light intensity activity and lower sedentary times were both associated with lower BMI. This was evident using objective measures of lower-light intensity, and both objective and self-reported measures of higher-light intensity activity. Time spent watching television was positively associated with BMI, while reading and computer use were not. Greater time spent in higher but not lower intensities of light activity (assessed objectively) was associated with greater grip strength in men but not women, while neither objectively assessed nor self-reported sedentary time was associated with grip strength. Conclusions In this cross-sectional study, greater time spent in light intensity activity and lower sedentary times were associated with lower BMI. These results are consistent with the hypothesis that replacing sedentary activities with light intensity activities could lead to lower BMI levels and obesity

    Abstract Background: Surgical site infections (SSI) occur in 1.8%–9.2% of women undergoing cesarean section (CS) and lead to greater morbidity rates and increased treatment costs. The aim of the study was to evaluate the efficacy and cost-effectiveness of dialkylcarbamoyl chloride (DACC) impregnated dressings to prevent SSI in women subject to CS. Methods: Randomized, controlled trial was conducted at the Mazovian Bródno Hospital, a tertiary care center performing approximately 1300 deliveries per year, between June 2014 and April 2015. Patients were randomly allocated to receive either DACC impregnated dressing or standard surgical dressing (SSD) following skin closure. In order to analyze cost-effectiveness of the selected dressings in the group of patients who developed SSI, the costs of ambulatory visits, additional hospitalization, nursing care, and systemic antibiotic therapy were assessed. Independent risk factors for SSI were determined by multivariable logistic regression. Results: Five hundred and forty-three women undergoing elective or emergency CS were enrolled. The SSI rates in the DACC and SSD groups were 1.8% and 5.2%, respectively (p = 0.04). The total cost of SSI prophylaxis and treatment was greater in the control group as compared with the study group (5775 EUR vs. 1065 EUR, respectively). Independent risk factors for SSI included higher pre-pregnancy body mass index (adjusted odds ratio [aOR] = 1.08; [95% confidence interval [CI]: 1.0–1.2]; p < 0.05), smoking in pregnancy (aOR = 5.34; [95% CI: 1.6–15.4]; p < 0.01), and SSD application (aOR = 2.94; [95% CI: 1.1–9.3]; p < 0.05). Conclusion: The study confirmed the efficacy and cost-effectiveness of DACC impregnated dressings in SSI prevention among women undergoing CS. PMID:26891115

  14. Cost utility analysis of reduced intensity hematopoietic stem cell transplantation in adolescence and young adult with severe thalassemia compared to hypertransfusion and iron chelation program

    2013-01-01

    Background Hematopoieticic stem cell transplantation is the only therapeutic option that can cure thalassemia disease. Reduced intensity hematopoietic stem cell transplantation (RI-HSCT) has demonstrated a high cure rate with minimal complications compared to other options. Because RI-HSCT is very costly, economic justification for its value is needed. This study aimed to estimate the cost-utility of RI-HSCT compared with blood transfusions combined with iron chelating therapy (BT-ICT) for adolescent and young adult with severe thalassemia in Thailand. Methods A Markov model was used to estimate the relevant costs and health outcomes over the patients’ lifetimes using a societal perspective. All future costs and outcomes were discounted at a rate of 3% per annum. The efficacy of RI-HSCT was based a clinical trial including a total of 18 thalassemia patients. Utility values were derived directly from all patients using EQ-5D and SF-6D. Primary outcomes of interest were lifetime costs, quality adjusted life-years (QALYs) gained, and the incremental cost-effectiveness ratio (ICER) in US ($) per QALY gained. One-way and probabilistic sensitivity analyses (PSA) were conducted to investigate the effect of parameter uncertainty. Results In base case analysis, the RI-HSCT group had a better clinical outcomes and higher lifetime costs. The incremental cost per QALY gained was US $ 3,236 per QALY. The acceptability curve showed that the probability of RI-HSCT being cost-effective was 71% at the willingness to pay of 1 time of Thai Gross domestic product per capita (GDP per capita), approximately US $ 4,210 per QALY gained. The most sensitive parameter was utility of severe thalassemia patients without cardiac complication patients. Conclusion At a societal willingness to pay of 1 GDP per capita, RI-HSCT was a cost-effective treatment for adolescent and young adult with severe thalassemia in Thailand compared to BT-ICT.

    This article reports a study of the physical design characteristics of a set of adult intensive care units (ICUs), built between 1993 and 2003. These ICUs were recognized as the best-practice examples by the Society of Critical Care Medicine, the American Association of Critical Care Nurses, and the American Institute of Architects. This study is based on a systematic analysis of the materials found on these ICUs in the booklet and videos jointly published by the above organizations in 2005. The study finds that most of these examples of best-practice adult ICUs have the following negative characteristics: (1) they are built as renovation projects with more health and safety hazards during construction; (2) most of them are mixed-service units with more safety and staffing problems; (3) the overall layout and the layout of staff work areas in these ICUs do not have any common design solutions for improved patient and staff outcomes; and (4) in these ICUs, family space is often located outside the unit, and family access to the patient room is restricted, even though family presence at the bedside may be important for improved patient outcomes. Some of these negative characteristics are offset by the following positive characteristics in most ICUs: (1) they have only private patient rooms for improved patient care, safety, privacy, and comfort; (2) most patient beds are freestanding for easy access to patients from all sides; (3) they have handwashing sinks and waste disposal facilities in the patient room for improved safety; and (4) most patient rooms have natural light to help patients with circadian rhythms. The article discusses, in detail, the implications of its findings, and the role of the ICU design community in a very complicated design context. PMID:17063097

    There has been significant progress throughout 2014 in cardiothoracic and vascular anaesthesia and intensive care. There has been a revolution in the clinical approach to acute and chronic adult aortic diseases. Contemporary management of adult aortic disease is based on etiology, clinical presentation, extent, and integrated intervention with medical, endovascular and/or surgical measures. Further European guidelines have explored in depth the cardiovascular management in non-cardiac surgery with a thematic focus to reduce perioperative mortality from the leading offender, namely myocardial ischemia. Integrated guidelines address the management of myocardial revascularization including the percutaneous and surgical options. Despite 50 years since the first coronary artery bypass grafting procedure and impressive advances in interventional cardiology, surgical revascularization remains a gold standard for many patients with coronary artery disease. These advances in 2014 will likely further improve perioperative outcomes for our patients. PMID:26157736

    ABSTRACT Introduction: Young Liberians, particularly undereducated young adults, face substantial sexual and reproductive health (SRH) challenges, with low uptake of contraceptive methods, high rates of unintended pregnancy, and low levels of knowledge about HIV status. The purpose of this study was to assess the impact of a 6-day intensive group learning intervention combined with on-site SRH services (called HealthyActions) among out-of-school young adults, implemented through an existing alternative education program, on uptake of contraception and HIV testing and counseling (HTC). Methods: The intervention was implemented among young women and men ages 15–35 who were enrolled in alternative basic education learning sites in 5 counties of Liberia. We conducted a randomized evaluation to assess program impact. Baseline data were collected in January–March 2014, and endline data in June–July 2014. Key outcomes of condom use, contraceptive use, and HTC were estimated with difference-in-difference models using fixed effects. All analyses were conducted in Stata 13. Results: We assessed outcomes for 1,157 learners at baseline and 1,052 learners at endline, across 29 treatment and 26 control sites. After adjusting for potential confounders, learners in the HealthyActions intervention group were 12% less likely to report never using a condom with a regular partner over the last month compared with the control group (P = .02). Female learners who received HealthyActions were 13% more likely to use any form of modern contraception compared with learners in control sites (P<.001), with the greatest increase in the use of contraceptive implants. Learners in HealthyActions sites were 45% more likely to have received HTC (P<.001). Conclusion: Providing intensive group learning in a supportive environment coupled with on-site health services improved SRH outcomes among participating learners. The focus of HealthyActions on participatory learning for low

    Objectives To assess the safety and acceptance of the PrePex device for medical male circumcision (MMC) in rural Uganda. Methods In an observational study, HIV-uninfected, uncircumcised men aged 18 and older who requested elective MMC were informed about the PrePex and dorsal slit methods and offered a free choice of their preferred procedure. 100 men received PrePex to assess preliminary safety (aim 1). An additional 329 men, 250 chose PrePex and 79 chose Dorsal slit, were enrolled following approval by the Safety Monitoring Committee (aim 2). Men were followed up at 7 days to assess adverse events (AEs) and to remove the PrePex device. Wound healing was assessed at 4 weeks, with subsequent weekly follow up until completed healing. Results The PrePex device was contraindicated in 5.7% of men due to a tight prepuce or phimosis/adhesions. Among 429 enrolled men 350 (82.0%) got the PrePex device and 79 (18.0%) the dorsal slit procedure. 250 of 329 men (76.0%) who were invited to choose between the 2 procedures chose Prepex. There were 9 AEs (2.6%) with the PrePex, of which 5 (1.4%) were severe complications, 4 due to patient self-removal of the device leading to edema and urinary obstruction requiring emergency surgical circumcision, and one due to wound dehiscence following device removal. 71.8% of men reported an unpleasant odor prior to PrePex removal. Cumulative rates of completed wound healing with the PrePex were 56.7% at week 4, 84.8% week 5, 97.6% week 6 and 98.6% week 7, compared to 98.7% at week 4 with dorsal slit (p<0.0001). Conclusion The PrePex device was well accepted, but healing was slower than with dorsal slit surgery. Severe complications, primarily following PrePex self-removal, required rapid access to emergency surgical facilities. The need to return for removal and delayed healing may increase Program cost and client burden. PMID:25144194

    Housing First (HF) is being widely disseminated in efforts to end homelessness among homeless adults with psychiatric disabilities. This study evaluates the effectiveness of HF with Intensive Case Management (ICM) among ethnically diverse homeless adults in an urban setting. 378 participants were randomized to HF with ICM or treatment-as-usual (TAU) in Toronto (Canada), and followed for 24 months. Measures of effectiveness included housing stability, physical (EQ5D-VAS) and mental (CSI, GAIN-SS) health, social functioning (MCAS), quality of life (QoLI20), and health service use. Two-thirds of the sample (63%) was from racialized groups and half (50%) were born outside Canada. Over the 24 months of follow-up, HF participants spent a significantly greater percentage of time in stable residences compared to TAU participants (75.1% 95% CI 70.5 to 79.7 vs. 39.3% 95% CI 34.3 to 44.2, respectively). Similarly, community functioning (MCAS) improved significantly from baseline in HF compared to TAU participants (change in mean difference = +1.67 95% CI 0.04 to 3.30). There was a significant reduction in the number of days spent experiencing alcohol problems among the HF compared to TAU participants at 24 months (ratio of rate ratios = 0.47 95% CI 0.22 to 0.99) relative to baseline, a reduction of 53%. Although the number of emergency department visits and days in hospital over 24 months did not differ significantly between HF and TAU participants, fewer HF participants compared to TAU participants had 1 or more hospitalizations during this period (70.4% vs. 81.1%, respectively; P=0.044). Compared to non-racialized HF participants, racialized HF participants saw an increase in the amount of money spent on alcohol (change in mean difference = $112.90 95% CI 5.84 to 219.96) and a reduction in physical community integration (ratio of rate ratios = 0.67 95% CI 0.47 to 0.96) from baseline to 24 months. Secondary analyses found a significant reduction in the number of days

    The goal of surgical treatment of adolescent idiopathic scoliosis (AIS) is to prevent disability associated with curve progression. Few investigators have considered whether the function of patients with AIS becomes adversely affected by major spine fusion surgery. Tertiary referral center patients (age, 10-17 years) who underwent spinal deformity correction a minimum of 5 years earlier were identified. Scoliosis Research Society-22R (SRS-22R) and Short Form-12 (SF-12) were administered. Data were available for 118 patients. Mean age was 14.1 years at surgery and 26.8 years at follow-up. Mean outcome scores were 50.9 (SF-12 physical composite summary), 49.4 (SF-12 mental composite summary), and 4.0 (SRS-22R total). One hundred patients (85%) were working. Common symptoms included occasional back pain (90, 76%), limited range of motion (52, 44%), activity limitations (54, 46%), waistline imbalance (41, 35%), rib prominence (28, 24%), wound/scar problems (18, 15%), and shortness of breath (18, 15%). Prominent implants were reported by 11 patients (9%). Seven of 14 reoperations were for instrumentation removal. There was a high incidence of occasional back pain and activity complaints after surgery for AIS in our cohort. However, normal SF-12 scores suggested that these symptoms did not lower the patients' general health.

    The aim of study was to compare clinical and pathologic findings of surgically removed thyroid tumors in adults with or without history of irradiation due to the Chernobyl accident. From 1990 to 2003, 2363 adults with no evidence of radiation influence in their history (group A) have undergone operation for thyroid nodules. During the same period, 311 patients (born before 1969) with strict evidence of Chernobyl irradiation also underwent operation (group B). Both groups were similar in age, sex, and preoperative examination. Group B represented three of the four official categories of people affected by the Chernobyl accident: 1-recovery operation workers; 2-people evacuated from the restricted area; 3-inhabitants of contaminated areas. The rate of thyroid carcinoma among all cases of thyroid nodules was significantly higher in group B--32.8% (102 patients) versus 27.2% (644 patients) in group A (p < 0.05). But a more distinct difference was observed in 1 and 2 categories of group B patients (the rate of cancer was, correspondingly, 54.8% and 47.8%;p < 0.01). The percentage of the invasive form of cancer (T4) was significantly higher in irradiated patients-39% versus 23% (p < 0.05) as were regional metastases (N1a,1b)--41% versus 19% (p < 0.01) and frequency of multifocality (33% versus 24%; p < 0.05). The most distinguished features were found in 1 category of group B: T4--in 47%, N1a-1b--in 62%, multifocality--in 41%. Our results suggest the irradiation as a cause of thyroid cancer in adult victims of Chernobyl and confirm the increasing aggressiveness of such tumors.

    The role of physical activity as a factor that protects against stress-related mental disorders is well documented. Nevertheless, there is still a dearth of research using objective measures of physical activity. The present study examines whether objectively assessed vigorous physical activity (VPA) is associated with mental health benefits beyond moderate physical activity (MPA). Particularly, this study examines whether young adults who accomplish the American College of Sports Medicine's (ACSM) vigorous-intensity exercise recommendations differ from peers below these standards with regard to their level of perceived stress, depressive symptoms, perceived pain, and subjective and objective sleep. A total of 42 undergraduate students (22 women, 20 men; M=21.24years, SD=2.20) volunteered to take part in the study. Stress, pain, depressive symptoms, and subjective sleep were assessed via questionnaire, objective sleep via sleep-EEG assessment, and VPA via actigraphy. Meeting VPA recommendations had mental health benefits beyond MPA. VPA was associated with less stress, pain, subjective sleep complaints and depressive symptoms. Moreover, vigorous exercisers had more favorable objective sleep pattern. Especially, they had increased total sleep time, more stage 4 and REM sleep, more slow wave sleep and a lower percentage of light sleep. Vigorous exercisers also reported fewer mental health problems if exposed to high stress. This study provides evidence that meeting the VPA standards of the ACSM is associated with improved mental health and more successful coping among young people, even compared to those who are meeting or exceeding the requirements for MPA.

    OBJECTIVE To assess the relative impact of an intensive lifestyle intervention (ILI) on use and costs of health care within the Look AHEAD trial. RESEARCH DESIGN AND METHODS A total of 5,121 overweight or obese adults with type 2 diabetes were randomly assigned to an ILI that promoted weight loss or to a comparison condition of diabetes support and education (DSE). Use and costs of health-care services were recorded across an average of 10 years. RESULTS ILI led to reductions in annual hospitalizations (11%, P = 0.004), hospital days (15%, P = 0.01), and number of medications (6%, P < 0.001), resulting in cost savings for hospitalization (10%, P = 0.04) and medication (7%, P < 0.001). ILI produced a mean relative per-person 10-year cost savings of $5,280 (95% CI 3,385–7,175); however, these were not evident among individuals with a history of cardiovascular disease. CONCLUSIONS Compared with DSE over 10 years, ILI participants had fewer hospitalizations, fewer medications, and lower health-care costs. PMID:25147253

    Background Safe Male Circumcision (SMC) is a proven approach for partial protection of men from acquisition of HIV infection. Several sub-Saharan African countries have a target to circumcise 80% of males aged 15 to 49. The use of devices such as PrePex would aid scaling up of SMC. Since most health workers would have no prior experience with use of devices, skills training is needed. This paper explores a skills transfer model at an urban site in Uganda. Objective To assess the practicability and feasibility of rapid short duration training for safe PrePex device use. Methods A prospective study, conducted over 8 weeks (August–October 2012) at International Hospital Kampala, an urban Kampala hospital, examining the performance of various health worker cadres after training in the use of a non-surgical device (PrePex). The prospective study obtained approval from the Makerere School of Medicine Research and Ethics Committee and the Uganda National Council of Science and Technology. If eligible, and after the subject signed the informed consent form, they were enrolled into the study. Results Ten health workers were successfully trained in use of PrePex during a 3 day non-residential on-the-job training course. After the first three days of training, the trained health workers performed 561 placements and 529 device removals successfully. Over all adverse events (AE) rates were below ≤2%; however, there were some differences in AE rates across the cadres trained but not significant (p>0.25 for moderate AEs). Conclusion Rapid training for safe use of the PrePex device is feasible for the range of health workers available for SMC in resource limited settings, but among those with past SMC experience.

The principal aim of this study was to determine whether individuals with knee-disarticulation amputations have worse pain and pain-related interference with physical function than do individuals with transtibial or transfemoral amputations. We analyzed cross-sectional survey data provided by 42 adults with lower-limb amputations. These individuals consisted of 14 adults reporting knee-disarticulation amputation in one limb and best-matched cases (14 reporting transfemoral amputation and 14 reporting transtibial amputation) from a larger cross-sectional sample of 472 individuals. Participants were rigorously matched based on time since amputation, reason for amputation, age, sex, diabetes diagnosis, and pain before amputation. Continuous outcome variables were analyzed by one-way analysis of variance. Categorical outcomes were analyzed by Pearson chi-square statistic. Given the relatively small sample size and power concerns, mean differences were also described by estimated effect size (Cohen’s d). Of the 42 participants, 83% were male. They ranged in age from 36 to 85 (median = 55.1, standard deviation = 11.0). Most amputations were of traumatic origin (74%), and participants were on average 12.4 years from their amputations at the time of the survey. Individuals with transtibial amputation reported significantly more prosthesis use than did individuals with knee-disarticulation amputation. Amputation levels did not significantly differ in phantom limb pain, residual limb pain, back pain, and pain-related interference with physical function. Estimates of effect size, however, indicated that participants with knee-disarticulation amputation reported less phantom limb pain, phantom limb pain-related interference with physical function, residual limb pain, residual limb pain-related interference with

    Objective To systematically review and describe currently available approaches to supporting maintenance of weight loss in obese adults and to assess the evidence for the effectiveness of these interventions. Design Systematic review with meta-analysis. Data sources Medline, PsycINFO, Embase, and the Cochrane Central Register of Controlled Trials. Study selection Studies were identified through to January 2014. Randomised trials of interventions to maintain weight loss provided to initially obese adults (aged ≥18) after weight loss of ≥5% body weight with long term (≥12 months) follow-up of weight change (main outcome) were included. Study appraisal and synthesis Potential studies were screened independently and in duplicate; study characteristics and outcomes were extracted. Meta-analyses were conducted to estimate the effects of interventions on weight loss maintenance with the inverse variance method and a random effects model. Results are presented as mean differences in weight change, with 95% confidence intervals. Results 45 trials involving 7788 individuals were included. Behavioural interventions focusing on both food intake and physical activity resulted in an average difference of −1.56 kg (95% confidence interval −2.27 to −0.86 kg; 25 comparisons, 2949 participants) in weight regain compared with controls at 12 months. Orlistat combined with behavioural interventions resulted in a −1.80 kg (−2.54 to −1.06; eight comparisons, 1738 participants) difference compared with placebo at 12 months. All orlistat studies reported higher frequencies of adverse gastrointestinal events in the experimental compared with placebo control groups. A dose-response relation for orlistat treatment was found, with 120 mg doses three times a day leading to greater weight loss maintenance (−2.34 kg, −3.03 to −1.65) compared with 60 mg and 30 mg three times a day (−0.70 kg, 95% confidence interval −1.92 to 0.52), P=0.02. Conclusions Behavioural

    An increasing number of patients with congenital heart disease survive to adulthood. Expert opinion suggests that noncardiac surgery is a high-risk event, but few data describe perioperative outcomes in this population. Using the National Surgical Quality Improvement Program database, we identified a cohort of patients aged 18 to 39 years with prior heart surgery who underwent noncardiac surgery between 2005 and 2010. A comparison cohort with no prior cardiovascular surgery was matched on age, sex, race/ethnicity, operation year, American Society of Anesthesiologists physical status, and Current Procedural Terminology code. A study cohort consisting of 1191 patients was compared with a cohort of 5127 patients. Baseline dyspnea, inpatient status at the time of surgery, and a prior operation within 30 days were more common in the study cohort. Postoperative outcomes were less favorable in the study cohort. Observed rates of death, perioperative cardiac arrest, myocardial infarction, stroke, respiratory complications, renal failure, sepsis, venous thromboembolism, perioperative transfusion, and reoperation were significantly higher in the study cohort (P < 0.01 for all). Mean postoperative length of stay was greater in the study cohort (5.8 vs 3.6 days, P < 0.01). Compared with a matched control cohort, young adult patients with a history of prior cardiac surgery experienced significantly greater perioperative morbidity and mortality after noncardiac surgery. A history of prior cardiac surgery represents a marker of substantial perioperative risk in this young population that is not accounted for by the matched variables. These results suggest that adult patients with congenital heart disease are at risk for adverse outcomes and support the need for further registry-based investigations.

    The pedagogical approach to surgical training has changed significantly over the past few decades. No longer are surgical skills solely acquired through a traditional apprenticeship model of training. The acquisition of many technical and nontechnical skills is moving from the operating room to the surgical skills laboratory through the use of simulation. Many platforms exist for the learning and assessment of surgical skills. In this article, the authors provide a broad overview of some of the currently available surgical simulation modalities including bench-top models, laparoscopic simulators, simulation for new surgical technologies, and simulation for nontechnical surgical skills.

    Successful innovative 'leaps' in surgical technique have the potential to contribute exponentially to surgical advancement, and thereby to improved health outcomes for patients. Such innovative leaps often occur relatively spontaneously, without substantial forethought, planning, or preparation. This feature of surgical innovation raises special challenges for ensuring sufficient evaluation and regulatory oversight of new interventions that have not been the subject of controlled investigatory exploration and review. It is this feature in particular that makes early-stage surgical innovation especially resistant to classification as 'research', with all of the attendant methodological and ethical obligations--of planning, regulation, monitoring, reporting, and publication--associated with such a classification. This paper proposes conceptual and ethical grounds for a restricted definition according to which innovation in surgical technique is classified as a form of sui generis surgical 'research', where the explicit goal of adopting such a definition is to bring about needed improvements in knowledge transfer and thereby benefit current and future patients.

    OBJECTIVE: The objectives were to review adult intussusception, its diagnosis, and its treatment. SUMMARY BACKGROUND DATA: Adult intussusception represents 1% of all bowel obstructions, 5% of all intussusceptions, and 0.003%-0.02% of all hospital admissions. Intussusception is a different entity in adults than it is in children. METHODS: The records of all patients 18 years and older with the postoperative diagnosis of intussusception at the Massachusetts General Hospital during the years 1964 through 1993 were reviewed retrospectively. The 58 patients were divided into those with benign enteric, malignant enteric, benign colonic, and malignant colonic lesions associated with their intussusception. The diagnosis and treatment of each were reviewed. RESULTS: In 30 years at the Massachusetts General Hospital, there are 58 cases of surgically proven adult intussusception. The patients' mean age was 54.4 years. Most patients presented with symptoms consistent with bowel obstruction. There were 44 enteric and 14 colonic intussusceptions. Ninety-three percent of the intussusceptions were associated with a pathologic lesion. Forty-eight percent of the enteric lesions were malignant and 52% were benign. Forty-three percent of the colonic lesions were malignant and 57% were benign. CONCLUSIONS: Intussusception occurs rarely in adults. It presents with a variety of acute, intermittent, and chronic symptoms, thus making its preoperative diagnosis difficult. Computed tomography scanning proved to be the most useful diagnostic radiologic method. The diagnosis and treatment of adult intussusception are surgical. Surgical resection of the intussusception without reduction is the preferred treatment in adults, as almost half of both colonic and enteric intussusceptions are associated with malignancy.

    Surgical fusion of the subtalar joint is a procedure indicated to alleviate pain of subtalar origin, such as in post-traumatic osteoarthritis, adult-acquired flatfoot deformity, and other disorders. Open subtalar arthrodesis has been performed with predictable results, but concerns exist regarding injury to proprioception and local vascularity due to wide surgical dissection. Minimally invasive techniques try to improve results by avoiding these issues but have a reputation for being technically demanding. We describe the surgical technique for arthroscopic subtalar arthrodesis, which has proved to be a safe and reliable technique in our experience, with consistent improvements in American Orthopaedic Foot & Ankle Society scores.

    2010-10-01

    Over recent decades, specialized paediatric cardiac intensive care has emerged as a central component in the management of critically ill, neonatal, paediatric and adult patients with congenital and acquired heart disease. The majority of high-volume centres (dealing with over 300 surgical cases per year) have dedicated paediatric cardiac intensive care units, with the smallest programmes more likely to care for paediatric cardiac patients in mixed paediatric or adult intensive care units. Specialized nursing staff are also a crucial presence at the patient's bedside for quality of care. A paediatric cardiac intensive care programme should have patients (preoperative and postoperative) grouped together geographically, and should provide proximity to the operating theatre, catheterization laboratory and radiology department, as well as to the regular ward. Age-appropriate medical equipment must be provided. An optimal strategy for running a paediatric cardiac intensive care programme should include: multidisciplinary collaboration and involvement with paediatric cardiology, anaesthesia, cardiac surgery and many other subspecialties; a risk-stratification strategy for quantifying perioperative risk; a personalized patient approach; and anticipatory care. Finally, progressive withdrawal from heavy paediatric cardiac intensive care management should be institutionalized. Although the countries of the European Union do not share any common legislation on the structure and organization of paediatric intensive care or paediatric cardiac intensive care, any paediatric cardiac surgery programme in France that is agreed by the French Health Ministry must perform at least '150 major procedures per year in children' and must provide a 'specialized paediatric intensive care unit'.

    1982-12-01

    Multipurpose surgical CO2 lasers marketed in the USA have been developed to be applicable to a variety of surgical procedures in many surgical fields. They are all suited for endoscopic surgical procedures and can be fitted to all standard surgical microscopes. They all can adjust the focal length of the laser beam to the different standard focal lengths of the surgical microscope which for instance in laryngoscopy is 400 mm and in colposcopy 300 mm. One laser instrument can even change the spot size in a given focal distance which is very advantageous for some microsurgical procedures (Merrimack Laboratories 820). All multipurpose surgical CO2 laser systems provide a multi-articulated surgical arm for free-hand surgery. The surgical arms are cumbersome to use but they are adapted to the surgeons needs with ingenuity. The practicality of the multi-articulated surgical arms depends mostly on the distance of the handpiece from the surgical console which now is also overbridged by the laser tube in most surgical laser system. The spot size of the beam is variable in most handpieces by interchangeable lenses which modify the focal distance of the beam and the power density. Another common feature in all systems is a coaxial He-Ne pilot light which provides a red spot which unfortunately becomes invisible in a bleeding surgical field. Most surgical laser systems have a spacial mode of TEM 00 which is essential for incisional surgery. The continuous mode of beam delivery is used for incisional surgery and also for most endoscopic procedures.

    Acute myeloid leukemia is the most common indication for an allogeneic hematopoietic cell transplant. The introduction of reduced intensity conditioning has expanded the recipient pool for transplantation, which has importantly made transplant an option for the more commonly affected older age groups. Reduced intensity conditioning allogeneic transplantation is currently the standard of care for patients with intermediate or high-risk acute myeloid leukemia and is now most often employed in older patients and those with medical comorbidities. Despite being curative for a significant proportion of patients, post-transplant relapse remains a challenge in the reduced intensity conditioning setting. Herein we discuss the studies that demonstrate the feasibility of reduced intensity conditioning allogeneic transplants, compare the outcomes of reduced intensity conditioning versus chemotherapy and conventional myeloablative conditioning regimens, describe the optimal donor and stem cell source, and consider the impact of post-remission consolidation, comorbidities, center experience, and more intensive (reduced toxicity conditioning) regimens on outcomes. Additionally, we discuss the need for further prospective studies to optimize transplant outcomes. PMID:26130513

    Purpose This study examined whether the perceived taste intensity of liquids with chemesthetic properties influenced lingua-palatal pressures and submental surface electromyography (sEMG) in swallowing, compared to water. Method Swallowing behaviors were studied in 80 healthy women, stratified by age-group and genetic taste-status. General Labeled Magnitude Scale ratings of taste intensity were collected for deionized water; carbonated water; 2.7 % w/v citric acid; and diluted ethanol. These stimuli were swallowed, with measurement of tongue-palate pressures and submental sEMG. Path analysis differentiated stimulus, genetic taste-status, age, and perceived taste intensity effects on swallowing. Signal amplitude during effortful saliva swallowing served as a covariate accounting for differences in participant strength. Results Significant differences in taste intensity were seen across liquids: citric acid > ethanol > carbonated water > water. Supertasters perceived greater taste intensity than nontasters. Lingua-palatal pressure and sEMG amplitudes were correlated with the strength covariate. Anterior palate pressures and sEMG amplitudes were significantly higher for the citric acid stimulus. Perceived taste intensity was a significant mediator of stimulus differences. Conclusions These data support the idea that sensory input transmitted via chorda tympani and trigeminal afferent pathways may lead to cortical facilitation and/or modulation of swallowing.

    Harvey W. Cushing (1869-1939) is the only surgeon represented in Surgical Research IV and one of the most accomplished American contributors to surgical research in general and to neurological and endocrine surgery research in particular. Other surgical research leaders of the 19th and 20th centuries who preceded Harvey Cushing have been introduced before. First, we highlighted the "importance of medical and surgical research" as the basic elements in the advancement of medicine and surgery could be considered as Surgical Research I. Second, in Surgical Research II, we presented William Beaumont, Samuel Gross, and William Halsted as the most important participants of the first wave of American surgical researchers. Next, in Surgical Research III, we considered surgeon researchers who moved ahead in the field of surgery with their research initiatives at the time, including John B. Murphy, the Mayo Brothers William J. and Charles H. Mayo, and George W. Crile. With Harvey Cushing, we enter an era of surgical research associated with neurosurgery and endocrine surgery as part of Surgical Research IV. PMID:20690841

    Background Several circumcision devices have been evaluated for a safe and simplified male circumcision among adults. The PrePex device was prequalified for voluntary male medical circumcision (VMMC) in May 2013 by the World Health Organization and is expected to simplify the procedure safely while reducing cost. South Africa is scaling up VMMC. Objective To evaluate the overall unit cost of VMMC at a mixed site vs. a hypothetical PrePex-only site in South Africa. Design We evaluated the overall unit cost of VMMC at a mixed site where PrePex VMMC procedure was added to routine forceps-guided scalpel-based VMMC in Soweto, South Africa. We abstracted costs and then modeled these costs for a hypothetical PrePex-only site, at which 9,600 PrePex circumcisions per year could be done. We examined cost drivers and modeled costs, varying the price of the PrePex device. The healthcare system perspective was used. Results In both sites, the main contributors of cost were personnel and consumables. If 10% of all VMMC were by PrePex at the mixed site, the overall costs of the surgical method and PrePex were similar – US$59.62 and $59.53, respectively. At the hypothetical PrePex-only site, the unit cost was US$51.10 with PrePex circumcisions having markedly lower personnel and biohazardous waste management costs. In sensitivity analysis with the cost of PrePex kit reduced to US$10 and $2, the cost of VMMC was further reduced. Conclusions Adding PrePex to an existing site did not necessarily reduce the overall costs of VMMC. However, starting a new PrePex-only site is feasible and may significantly reduce the overall cost by lowering both personnel and capital costs, thus being cost-effective in the long term. Achieving a lower cost for PrePex will be an important contributor to the scale-up of VMMC. PMID:26679407

    Over the course of 12 months, a plastic surgical team from Paris, France, undertook 2 intensive ear reconstruction missions with plastic surgeons from the CoRSU Rehabilitation Hospital in Uganda. A cohort of over 30 adult women was assessed having been subjected to ear amputations by members of the Lords Resistance Army in Northern Uganda in the 1990s. The patients were identified, mobilized, and transferred to Kampala for surgery by a charitable arm of the Watoto Church, known as Living Hope. The surgical team performed 15 ear reconstruction cases during the first 1-week mission and 16 ear reconstruction cases during the second 1-week mission. All cases were reconstructed successfully using the 2-stage autologous auricular reconstruction method advocated by the senior author (FF). Local skin was used to cover the costal cartilage framework in the first stage without need for temporo-parietal fascial flaps. Technical challenges included the older age of patients and ossified costal cartilage, high prevalence of HIV positivity, bilateral amputation, and difficulty of surgical follow-up. The main modifications to standard practice were routine pre-op testing of the costal cartilage, pre-op viral load and CD4 count screening in HIV-positive patients, simultaneous bilateral first-stage ear reconstruction, prolonged hospital stay, and implementation of routine surgical counting procedures.

    BACKGROUND Acute kidney injury (AKI) is an important complication in surgical patients. Existing biomarkers and clinical prediction models underestimate the risk for developing AKI. We recently reported data from two trials of 728 and 408 critically ill adult patients in whom urinary TIMP2•IGFBP7 (NephroCheck, Astute Medical) was used to identify patients at risk of developing AKI. Here we report a preplanned analysis of surgical patients from both trials to assess whether urinary tissue inhibitor of metalloproteinase 2 (TIMP-2) and insulin-like growth factor–binding protein 7 (IGFBP7) accurately identify surgical patients at risk of developing AKI. STUDY DESIGN We enrolled adult surgical patients at risk for AKI who were admitted to one of 39 intensive care units across Europe and North America. The primary end point was moderate-severe AKI (equivalent to KDIGO [Kidney Disease Improving Global Outcomes] stages 2–3) within 12 hours of enrollment. Biomarker performance was assessed using the area under the receiver operating characteristic curve, integrated discrimination improvement, and category-free net reclassification improvement. RESULTS A total of 375 patients were included in the final analysis of whom 35 (9%) developed moderate-severe AKI within 12 hours. The area under the receiver operating characteristic curve for [TIMP-2]•[IGFBP7] alone was 0.84 (95% confidence interval, 0.76–0.90; p < 0.0001). Biomarker performance was robust in sensitivity analysis across predefined subgroups (urgency and type of surgery). CONCLUSION For postoperative surgical intensive care unit patients, a single urinary TIMP2•IGFBP7 test accurately identified patients at risk for developing AKI within the ensuing 12 hours and its inclusion in clinical risk prediction models significantly enhances their performance. LEVEL OF EVIDENCE Prognostic study, level I. PMID:26816218

    Surgical treatment of talus fractures can challenge even the most skilled foot and ankle surgeon. Complicated fracture patterns combined with joint dislocation of variable degrees require accurate assessment, sound understanding of principles of fracture care, and broad command of internal fixation techniques needed for successful surgical care. Elimination of unnecessary soft tissue dissection, a low threshold for surgical reduction, liberal use of malleolar osteotomy to expose body fracture, and detailed attention to fracture reduction and joint alignment are critical to the success of treatment. Even with the best surgical care complications are common and seem to correlate with injury severity and open injuries. PMID:19121756

    Surgical ethics as a specific discipline is relatively new to many. Surgical ethics focuses on the ethical issues that are particularly important to the care of surgical patients. Informed consent for surgical procedures, the level of responsibility that surgeons feel for their patients' outcomes, and the management of surgical innovation are specific issues that are important in surgical ethics and are different from other areas of medicine. The future of surgical progress is dependent on surgical innovation, yet the nature of surgical innovation raises specific concerns that challenge the professionalism of surgeons. These concerns will be considered in the following pages.

    2014-01-01

    Surgical hip dislocation (SHD) is a versatile approach used to address both intra-articular and extra-articular pathology around the hip joint in both pediatric and adult patients. It allows anterior dislocation of the femoral head for direct visualization of the hip joint while preserving femoral head vascularity and minimizing trauma to the abductor musculature. Previously described indications for SHD include femoroacetabular impingement, deformity resulting from Legg-Calve-Perthes disease, slipped capital femoral epiphysis, periarticular trauma, benign lesions of the hip joint, and osteochondral lesions. In this review, we will describe current surgical techniques, indications, and clinical outcomes for SHD. PMID:25207733

    Split liver transplantation (SLT), while widely accepted in pediatrics, remains underutilized in adults. Advancements in surgical techniques and donor-recipient matching, however, have allowed expansion of SLT from utilization of the right trisegment graft to now include use of the hemiliver graft as well. Despite less favorable outcomes in the early experience, better outcomes have been reported by experienced centers and have further validated the feasibility of SLT. Importantly, more than two decades of experience have identified key requirements for successful SLT in adults. When these requirements are met, SLT can achieve outcomes equivalent to those achieved with other types of liver transplantation for adults. However, substantial challenges, such as surgical techniques, logistics, and ethics, persist as ongoing barriers to further expansion of this highly complex procedure. This review outlines the current state of SLT in adults, focusing on donor and recipient selection based on physiology, surgical techniques, surgical outcomes, and ethical issues. PMID:27672272

    Split liver transplantation (SLT), while widely accepted in pediatrics, remains underutilized in adults. Advancements in surgical techniques and donor-recipient matching, however, have allowed expansion of SLT from utilization of the right trisegment graft to now include use of the hemiliver graft as well. Despite less favorable outcomes in the early experience, better outcomes have been reported by experienced centers and have further validated the feasibility of SLT. Importantly, more than two decades of experience have identified key requirements for successful SLT in adults. When these requirements are met, SLT can achieve outcomes equivalent to those achieved with other types of liver transplantation for adults. However, substantial challenges, such as surgical techniques, logistics, and ethics, persist as ongoing barriers to further expansion of this highly complex procedure. This review outlines the current state of SLT in adults, focusing on donor and recipient selection based on physiology, surgical techniques, surgical outcomes, and ethical issues. PMID:27672272

    Hypertension, decreased glucose tolerance, adverse lipid profiles and low physical activity levels are associated with increased type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) risk. High intensity interval training (HIIT), a low volume, reduced time, high intensity programme, may be a useful alternative to current government guidelines which specify a minimum of 150 minutes of physical activity per week. We describe a personalised programme of high intensity exercise which provides significant improvements in CVD risk markers. Healthy volunteers undertook 6 weeks of HIIT. T2DM and CVD risk predictors including glucose tolerance, VO2max, blood pressure (BP), and lipids were measured before and after HIIT. HIIT training was associated with beneficial changes in a range of predictors of blood flow and cardiovascular risk. There was a heterogeneous response to HIIT, with some subjects responding with favourable changes and others being non-responders to HIIT. In responders, HIIT was associated with a statistically significant (p = 0.023) increase in VO2max, from 45.4 (38.4,52.5) to 56.9 (51.2,65.7) (median (interquartile range)(ml/min/kg)). In responders HIIT resulted in a decrease in systolic BP from 127 (126,129) to 116 (106,122) (mmHg) with p = 0.026 and a decrease is diastolic blood pressure from 72 (69,74) to 57 (56,66) with p = 0.026. There was also some evidence of a beneficial change in blood lipid and glucose concentrations with HIIT. In conclusion, personalised HIIT has potential as an intervention to improve blood flow and cardiovascular health.

    Over eight years, 58 rural Nigerians with pericarditis were treated surgically in Zaria using basic surgical facilities. Eighteen patients had purulent pericarditis, associated with staphylococcal pneumonia in children, or pneumococcal pneumonia in adults. Treatment with antibiotics and prompt pericardiectomy appeared to be superior to drainage, since a quarter of those initially treated with surgical drainage developed early constriction and required pericardiectomy soon after. Thirteen patients had chronic pericardial effusions, of whom one had epicardial constriction and two had cardiomyopathy. Twenty-seven patients had chronic constrictive pericarditis but tuberculosis was confirmed histologically in three only. Echocardiographic findings remained unchanged in five patients evaluated before and after pericardiectomy. Eight of the 13 patients who died had already developed myocardial or hepatic insufficiency before operation, because of late presentation or diagnosis. Greater awareness of the significance of precordial pain in this rural population where ischaemic heart disease is rare would help in making an earlier diagnosis. Images PMID:7314033

    High-intensity focused ultrasound (HIFU) is a technique that was first investigated in the 1940s as a method of destroying selective regions within the brain in neuro-surgical An ultrasound beam can be brought to a tight focus at a distance from its source, and if sufficient energy is concentrated within the focus, the cells lying within this focal volume are killed, whereas those lying elsewhere are spared. This is a noninvasive method of producing selective and trackless tissue destruction in deep seated targets in the body, without damage to overlying tissues. This field, known both as HIFU and focused ultrasound surgery (FUS), is reviewed in this article.

    A project was undertaken to improve robotic surgical tools for telerobotic minimally invasive surgery. The major objectives were to reduce the size of the tools to permit new surgical procedures in confined spaces such as the heart and to improve control of surgical tools by locating positional sensors and actuators at the end effector rather than external to the patient as is currently the state of the technology. A new compact end-effector with wrist-like flexibility was designed. Positional sensors based on MEMS microfabrication techniques were designed.

  16. Surgical progress: surgical management of infective endocarditis.

    Mills, S A

    1982-01-01

    Infective endocarditis of bacterial or fungal origin may arise in either the left or the right heart and can involve both natural and prosthetic valves. The diagnosis is based primarily upon clinical criteria and positive blood cultures, but serial electrocardiograms, fluoroscopy, and two-dimensional echocardiograms may also be helpful. The initial treatment should consist of antibiotic therapy and is itself often adequate in effecting cure. However, careful observation during antibiotic treatment is mandatory, since the development of congestive heart failure due to valvular obstruction or destruction can be an indication for surgical intervention. Other surgical indications include a failure to respond to antibiotic therapy, pulmonary or systemic emboli, evidence of abscess involving the valvular ring (particularly prevalent with prosthetic valve endocarditis), Brucella infection, and the onset of conduction disturbances. The goals of surgical treatment are removal of infective tissue, restoration of valve function, and correction of associated mechanical disorders. The results are surprisingly good, especially for a condition of this severity. Images Fig. 2. Fig. 3. Fig. 4. Fig. 5. Fig. 6. PMID:7065743

    Gingival recession represents a clinical condition in adults frequently encountered in the general dental practice. It is estimated that 23% of adults in the US have one or more tooth surfaces with ≥ 3 mm gingival recession. Clinicians often time face dilemmas of whether or not to treat such a condition surgically. Therefore, we were charged by the editorial board to answer this critical question: “Does gingival recession require surgical treatment?” An initial condensed literature search was performed using a combination of gingival recession and surgery controlled terms and keywords. An analysis of the search results highlights our limited understanding of the factors that often guide the treatment of gingival recession. Understanding the etiology, prognosis and treatment of gingival recession continues to offer many unanswered questions and challenges in the field of periodontics as we strive to provide the best care possible for our patients.

    Objectives To investigate the effects of a high-intensity functional exercise program on independence in activities of  daily living (ADLs) and balance in older people with dementia and whether exercise effects differed between dementia types. Design Cluster-randomized controlled trial: Umeå Dementia and Exercise (UMDEX) study. Setting Residential care facilities, Umeå, Sweden. Participants Individuals aged 65 and older with a dementia diagnosis, a Mini-Mental State Examination score of 10 or greater, and dependence in ADLs (N = 186). Intervention Ninety-three participants each were allocated to the high-intensity functional exercise program, comprising lower limb strength and balance exercises, and 93 to a seated control activity. Measurements Blinded assessors measured ADL independence using the Functional Independence Measure (FIM) and Barthel Index (BI) and balance using the Berg Balance Scale (BBS) at baseline and 4 (directly after intervention completion) and 7 months. Results Linear mixed models showed no between-group effect on ADL independence at 4 (FIM=1.3, 95% confidence interval (CI)=−1.6–4.3; BI=0.6, 95% CI=−0.2–1.4) or 7 (FIM=0.8, 95% CI=−2.2–3.8; BI=0.6, 95% CI=−0.3–1.4) months. A significant between-group effect on balance favoring exercise was observed at 4 months (BBS=4.2, 95% CI=1.8–6.6). In interaction analyses, exercise effects differed significantly between dementia types. Positive between-group exercise effects were found in participants with non-Alzheimer's dementia according to the FIM at 7 months and BI and BBS at 4 and 7 months. Conclusion In older people with mild to moderate dementia living in residential care facilities, a 4-month high-intensity functional exercise program appears to slow decline in ADL independence and improve balance, albeit only in participants with non-Alzheimer's dementia.

    Technological change, decreased financial support for medical education, and social oversight (in the form of the "To Err Is Human" report, HIPPA, and reduced work hours) are forcing a rethinking of the traditional model of surgical education to improve patient safety. New approaches to evaluating surgical competence, such as objective assessment, in combination with new technologies, such as the Internet and surgical simulators, provide the tools to effect a revolution in surgical education and training. Competency based upon quantifiable criteria measures must replace the traditional subjective assessment. The implementation requires accurately defining the elements of training, establishing new quantifiable metrics, stringently measuring performance against criterion, and reporting outcomes throughout the career of a surgeon.

    Traumatic brain injury (TBI) is one of the main causes of mortality and severe disability in young and middle age patients. Patients with severe TBI, who are in coma, are of particular concern. Adequate diagnosis of primary brain injuries and timely prevention and treatment of secondary injury mechanisms markedly affect the possibility of reducing mortality and severe disability. The present guidelines are based on the authors' experience in developing international and national recommendations for the diagnosis and treatment of mild TBI, penetrating gunshot wounds of the skull and brain, severe TBI, and severe consequences of brain injury, including a vegetative state. In addition, we used the materials of international and national guidelines for the diagnosis, intensive care, and surgical treatment of severe TBI, which were published in recent years. The proposed recommendations for surgical treatment of severe TBI in adults are addressed primarily to neurosurgeons, neurologists, neuroradiologists, anesthesiologists, and intensivists who are routinely involved in treating these patients.

    Brachymetatarsia describes the condition of an abnormally short metatarsal. Although the condition has been recorded since antiquity, surgical options to correct the deformity have been available for only two decades. Most published procedures involve metaphyseal lengthening with autogenous grafts from different donor sites. The author discusses one such surgical technique. In addition, the author proposes specific criteria for the objective diagnosis of brachymetatarsia. PMID:2406417

    Since its first description in 1992, laparoscopic adrenalectomy has become the gold standard for the surgical treatment of most adrenal conditions. The benefits of a minimally invasive approach to adrenal resection such as decreased hospital stay, shorter recovery time and improved patient satisfaction are widely accepted. However, as this procedure becomes more widespread, critical steps of the operation must be maintained to ensure expected outcomes and success. This article reviews the surgical techniques for the laparoscopic adrenalectomy. PMID:19468527

    The objective of this review is to evaluate the evidence regarding the use of music as an adjuvant therapy for pain control in hospitalized adults. The search terms music, music therapy, pain, adults, inpatient, and hospitalized were used to search the Cochrane Library, Cinahl, Medline, Natural Standard, and Scopus databases from January 2005 to March 2011. (A systematic review conducted by the Cochrane Collaboration has extensively covered the time frame from 1966 to 2004.) Seventeen randomized controlled trials met criteria for review and inclusion. Seven of the research studies were conducted with surgical patients, three with medical patients, one with medical-surgical patients, four with intensive care patients, and two with pregnant patients. The combined findings of these studies provide support for the use of music as an adjuvant approach to pain control in hospitalized adults. The use of music is safe, inexpensive, and an independent nursing function that can be easily incorporated into the routine care of patients. PMID:23107431

    Wilhelm Roentgen (1845-1923) created a surgical revolution with the discovery of the X-rays in late 1895 and the subsequent introduction of this technique for the management of surgical patients. No other physician or scientist had ever imagined such a powerful and worthwhile discovery. Other scientists paved the way for Roentgen to approach the use of these new X-rays for medical purposes. In this way, initially, and prior to Roentgen, Thompson, Hertz, and Lenard applied themselves to the early developments of this technology. They made good advances but never reached the clearly defined understanding brought about by Roentgen. The use of a Crookes tube, a barium platinocyanide screen, with fluorescent light and the generation of energy to propagate the cathode rays were the necessary elements for the conception of an X-ray picture. On November 8, 1895, Roentgen began his experiments on X-ray technology when he found that some kind of rays were being produced by the glass of the tube opposite to the cathode. The development of a photograph successfully completed this early imaging process. After six intense weeks of research, on December 22, he obtained a photograph of the hand of his wife, the first X-ray ever made. This would be a major contribution to the world of medicine and surgery.

The 6-month survival of 691 adult medical and surgical patients following intensive care was recorded and this data was analysed with admission and daily APACHE II scores using a relational database. Our data confirms the relationship between admission APACHE II scores and outcome, with mean scores decreasing as duration of survival increases. We also demonstrate that the best day one scores are approximately 50% less than the admission score, irrespective of outcome, indicating the benefit of intensive care. By contrast, however, the scores on day one have either not improved or have worsened since admission, reflecting the importance of the pre-morbid health status of the patient in determining outcome from intensive care.

    This single-center retrospective study aimed to report the impact of early hematopoietic and immune recoveries after a standard total body irradiation, cyclophosphamide, and fludarabine (TCF) reduced-intensity conditioning (RIC) regimen for double umbilical cord blood (dUCB) allogeneic stem cell transplantation (allo-SCT) in adults. We analyzed 47 consecutive patients older than 17 years who engrafted after a dUCB TCF allo-SCT performed between January 2006 and April 2013 in our department. Median times for neutrophil and platelet recoveries were 17 (range, 6 to 59) and 37 days (range, 0 to 164), respectively. The 3-year overall (OS) and disease-free survivals, relapse incidence, and nonrelapse mortality were 65.7%, 57.2%, 27.1%, and 19%, respectively. In multivariate analysis, higher day +30 monocyte (≥615/mm(3); hazard ratio [HR], .04; 95% confidence interval [CI], .004 to .36; P < .01) and day +42 lymphocyte (≥395/mm(3); HR, .16; 95% CI, .03 to .78; P = .02) counts were independently associated with better OS. These results suggest that early higher hematopoietic and immune recovery is predictive of survival after dUCB TCF RIC allo-SCT in adults. Factors other than granulocyte colony-stimulating factor, which was used in all cases, favoring expansion of monocytes or lymphocytes, should be tested in the future as part of the UCB transplantation procedure.

    In the myeloablative transplant setting, the early use of fluconazole prophylaxis provides a benefit in overall survival. Recent changes in transplantation practices, including the use of peripheral blood stem cells (PBSC) and/or reduced intensity conditioning (RIC) regimen may have favorably impacted the epidemiology of invasive fungal infections (IFI) after allogeneic stem cell transplantation (allo-SCT). Yet, the impact of removing fluconazole prophylaxis after RIC PBSC allotransplant is ill known. Here, a retrospective analysis was performed comparing patients who received fluconazole as antifungal prophylaxis (n = 53) or not (n = 56) after allo-SCT for acute leukemia or myelodysplastic/myeloproliferative syndrome. Sixteen IFI were documented (14 %) at a median time of 103 days after transplantation, including eight before day +100, at a similar rate, whether the patients received fluconazole prophylaxis (13 %) or not (16 %). IFI were due mainly to Aspergillus species (87 %), and only two Candida-related IFI (13 %) were documented in the non-fluconazole group before day +100. The incidences of IFI (overall, before or after day +100) as well as 3-year overall and disease-free survival, non-relapse mortality, or acute and chronic graft-versus-host disease (GVHD) were similar between both groups. In conclusion, this study suggests that fluconazole may not be required at the initial phase of RIC allo-SCT using PBSC. This result has to be confirmed prospectively while Aspergillus prophylaxis should be discussed in this particular setting.

    2013-01-01

    Background Several studies suggest that low 25(OH) vitamin D3 levels may be prognostic in some malignancies, but no studies have evaluated their impact on treatment outcome in acute myeloid leukemia (AML). Methods VD levels were evaluated in 97 consecutive newly diagnosed, intensively-treated AML patients. MicroRNA-expression profiles and single nucleotide polymorphisms (SNPs) in the 25(OH) vitamin D3 pathway genes were evaluated and correlated with 25(OH) vitamin D3 levels and treatment outcome. Results Thirty-four (35%) patients had normal 25(OH) vitamin D3 levels (32–100 ng/ml), 34 (35%) insufficient (20–31.9 ng/ml) and 29 (30%) deficient levels (<20 ng/ml). Insufficient/deficient 25(OH) vitamin D3 levels were associated with worse relapse-free survival (RFS) compared to normal vitamin D3 levels. In multivariate analyses, deficient 25(OH) vitamin D3, smoking, European LeukemiaNet Genetic Groups and white blood cell count retained their statistical significance for RFS. A number of microRNAs and SNPs were found to be associated with 25(OH) vitamin D3 level, although none remained significant after multiple test corrections; one 25(OH) vitamin D3 receptor SNP, rs10783219, was associated with lower complete remission rate (p=0.0442), shorter RFS (p=0.0058) and overall survival (p=0.0011). Conclusions It remains to be determined what role microRNA and SNP profiles play in contributing to low 25(OH) vitamin D3 level and/or outcome and whether supplementation will improve AML outcome.

    Facial reanimation following persistent facial paralysis can be managed with surgical procedures of varying complexity. The choice of the technique is mainly determined by the cause of facial paralysis, the age and desires of the patient. The techniques most commonly used are the nerve grafts (VII-VII, XII-VII, cross facial graft), dynamic muscle transfers (temporal myoplasty, free muscle transfert) and static suspensions. An intensive rehabilitation through specific exercises after all procedures is essential to archieve good results.

    A surgical procedure performed during space flight would occur in a unique microgravity environment. Several experiments performed during weightlessness in parabolic flight were reviewed to ascertain the behavior of surgical bleeding in microgravity. Simulations of bleeding using dyed fluid and citrated bovine blood, as well as actual arterial and venous bleeding in rabbits, were examined. The high surface tension property of blood promotes the formation of large fluid domes, which have a tendency to adhere to the wound. The use of sponges and suction will be adequate to prevent cabin atmosphere contamination with all bleeding, with the exception of temporary arterial droplet streams. The control of the bleeding with standard surgical techniques should not be difficult.

    Electro-surgical device is an essential instrument for bloodless surgery after the 1st introduction by Harvey Cushing in 1926. Basal mechanisms of electric scalpels (monopolar and bipolar), current waveforms (cut, coagulation and blend), high-frequency currents and electrical shocks were commented. After 1990s, several new electro-surgical devices such as argon beam coagulator, bipolar scissors and vessel sealing system (LigaSure) were developed and introduced in chest surgery. Argon beam coagulator is useful in sealing and hemostasis of bleeding from chest walls after extrapleural dissections. Bipolar scissors can seal small vessels less than diameter 2 mm and is useful in mediastinal lymphnode dissections. Vessel sealing system is able to seal and cut vessels up to diameter 7 mm. LigaSure V is the most suitable instrument for thymic vein handling in thoracoscopic thymectomy. Clinical applications of these new surgical devices in chest surgery are discussed. PMID:20715684

    Fragility fractures typically occur in elderly patients related principally to osteoporosis. A significative percentage of these fractures have to be treated surgically but comorbilities are often present, and need to be grossly stabilized before surgery. However, there is for these fractures a high rate of morbidity and mortality at short-term. Moreover, patients affected by a fragility fracture are at risk for another fragility fracture later in life. The Authors present an overview of the main patterns of proximal femoral fractures, underlining the peculiar features and choices of surgical treatment, and relating to specific indications and results of each treatment.

    Pulmonary cystic echinococcosis is a very rare disease in Germany. It is caused by the larvae of the dog tapeworm (echinococcus granulosus). The liver is the most affected organ, followed by the lungs. Surgery remains the main therapeutic approach for pulmonary CE. Whenever possible, parenchyma-preserving lung surgery should be preferred over anatomic lung resections. To ensure best therapeutic results, surgery needs to be performed under precise consideration of important infectiological aspects and patients should be treated in specialised centres based on interdisciplinary consensus. In addition to surgical aspects, this review summarises special infectiological features of this disease, which are crucial to the surgical approach. PMID:26351761

    Performing a surgical procedure during spaceflight will become more likely with longer duration missions in the near future. Minimal surgical capability has been present on previous missions as the definitive medical care time was short and the likelihood of surgical events too low to justify surgical hardware availability. Early demonstrations of surgical procedures in the weightlessness of parabolic flight indicated the need for careful logistical planning and restraint of surgical hardware. The consideration of human ergonomics also has more impact in weightlessness than in the conventionall-g environment. Three methods of surgical instrument restraint - a Minor Surgical Kit (MSK), a Surgical Restraint Scrub Suit (SRSS), and a Surgical Tray (ST) were evaluated in parabolic flight surgical procedures. The Minor Surgical Kit was easily stored, easily deployed, and demonstrated the best ability to facilitate a surgical procedure in weightlessness. Important factors in this surgical restraint system include excellent organization of supplies, ability to maintain sterility, accessibility while providing secure restraint, ability to dispose of sharp items and biological trash, and ergonomical efficiency.

    2004-01-01

    Constipation is a common symptom in clinical practice. Definition of constipation includes abnormal bowel frequency, difficulty during defecation and abnormal stool consistency. There are many classifications of constipation based on constipation etiology (constipation in healthy people caused by life style, constipation as a symptom of digestive tract diseases, secondary constipation in the course of systemic disorders or associated with drugs) and/or constipation mechanisms (functional, mechanical). The numerous disorders leading to constipation make often diagnostic management difficult and complicated. Treatment of constipation includes dietary and behavioral approaches, pharmacologic therapy and in selected patient surgical treatment. Surgical treatment is recommended in young patients with severe slow transit constipation refractory to conservative treatment. Confirmation of indication to surgical treatment requires studies of colonic and anorectal function (colonic transit studies, anorectal manometry, studies of defecation). Preferred surgical technique is colectomy with ileorectal anastomosis. Authors reported good results and patient satisfaction in 50-100 percent of cases. Postoperative complications include intestinal obstruction, abdominal pain, flatulence, diarrhea. PMID:15631313

    Temporal lobe epilepsy (TLE) is the most common form of adult epilepsy that is amenable to surgical treatment. In the carefully selected patient, excellent seizure outcome can be achieved with minimal or no side effects from surgery. This may result in improved psychosocial functioning, achieving higher education, and maintaining or gaining employment. The objective of this paper is to discuss the surgical selection process of a patient with TLE. We define what constitutes a patient that has medically refractory TLE, describe the typical history and physical examination, and distinguish between mesial TLE and neocortical TLE. We then review the role of routine (ambulatory/sleep-deprived electroencephalography (EEG), video EEG, magnetic resonance imaging (MRI), neuropsychological testing, and Wada testing) and ancillary preoperative testing (positron emission tomography, single-photon emission computed tomography (SPECT), subtraction ictal SPECT correlated to MRI (SISCOM), magnetoencephalography, magnetic resonance spectroscopy, and functional MRI) in selecting surgical candidates. We describe the surgical options for resective epilepsy surgery in TLE and its commonly associated risks while highlighting some of the controversies. Lastly, we present teaching cases to illustrate the presurgical workup of patients with medically refractory TLE. PMID:22957238

    Introduction: Rhabdomyolysis is a syndrome of injury of skeletal muscles associated with myoglobinuria, muscle weakness, electrolyte imbalance and often, acute kidney injury as severe complication. The aim: of this study is to detect the incidence of rhabdomyolysis in critically ill patients in the surgical intensive care unit (ICU), and to raise awareness of this medical condition and its treatment among the clinicians. Material and methods: A retrospective review of all surgical and trauma patients admitted to surgical ICU of the University Surgical Clinic “Mother Teresa” in Skopje, Macedonia, from January 1st till December 31st 2015 was performed. Patients medical records were screened for available serum creatine kinase (CK) with levels > 200 U/l, presence of myoglobin in the serum in levels > 80 ng/ml, or if they had a clinical diagnosis of rhabdomyolysis by an attending doctor. Descriptive statistical methods were used to analyze the collected data. Results: Out of totally 1084 patients hospitalized in the ICU, 93 were diagnosed with rhabdomyolysis during the course of one year. 82(88%) patients were trauma patients, while 11(12%) were surgical non trauma patients. 7(7.5%) patients diagnosed with rhabdomyolysis developed acute kidney injury (AKI) that required dialysis. Average values of serum myoglobin levels were 230 ng/ml, with highest values of > 5000 ng/ml. Patients who developed AKI had serum myoglobin levels above 2000 ng/ml. Average values of serum CK levels were 400 U/l, with highest value of 21600 U/l. Patients who developed AKI had serum CK levels above 3000 U/l. Conclusion: Regular monitoring and early detection of elevated serum CK and myoglobin levels in critically ill surgical and trauma patients is recommended in order to recognize and treat rhabdomyolysis in timely manner and thus prevent development of AKI.

    Intervening in Diabetes with Healthy Eating, Activity and Linkages To Healthcare (I-D-HEALTH) is a community-based randomized trial evaluating the effectiveness of a group-based adaption of the Look AHEAD intensive lifestyle intervention. Most potentially eligible patients were identified through electronic medical record queries or referral to a diabetes resource hub. Trial enrollees had a usual source of primary care, elevated body mass index (BMI) and type 2 diabetes. I-D-HEALTH participants were randomized to either standard care alone or standard care plus free-of-charge access to a group-based lifestyle intervention (GLI) offered by the YMCA. GLI participation was encouraged, but not required, for the latter group. The primary outcome is percent weight change over 6, 12 and 24months. Secondary outcomes include direct intervention costs and direct medical and non-medical expenditures, as well as changes in systolic blood pressure, hemoglobin A1c and cholesterol. Among 331 I-D-HEALTH participants, 167 were randomized to standard care and 164 to GLI. The mean age (±standard deviation) in each group was 57.1years (±12.2) and 57.6years (±10.5), respectively. Mean BMI was 34.9kg/m(2) (±7.3) among standard care participants and 36.2kg/m(2) (±7.8) among GLI participants. In both groups, approximately one third of participants were non-Hispanic Whites. We detected no significant differences between groups in mean systolic blood pressure, hemoglobin A1c or total cholesterol (P >0.05 for all characteristics above). The I-D-HEALTH study enrolled a diverse sample of adults with diabetes and offers a unique opportunity to evaluate the effectiveness of offering a community-based intensive lifestyle intervention.

    Recent advances in allogeneic stem cell transplantation (allo-HSCT) have included the advent of reduced-intensity conditioning (RIC) regimens to decrease the toxicity of myeloablative allo-SCT and the use of double umbilical cord blood (dUCB) units as a graft source in adults lacking a suitable donor. The FB2A2 regimen (fludarabine 30 mg/kg/day for 5-6 days + i.v. busulfan 3.6 mg/kg/day for 2 days + rabbit antithymocyte globulin 2.5 mg/kg/day for 2 days) supported by peripheral blood stem cells (PBSCs) and the TCF regimen (fludarabine 200 mg/m² for 5 days + cyclophosphamide 50 mg/kg for 1 day + low-dose [2 Gy] total body irradiation) supported by dUCB units are currently the most widely used RIC regimens in many centers and could be considered standard of care in adults eligible for an RIC allo-SCT. Here we compared, retrospectively, the outcomes of adults patients who received the FB2A2-PBSC RIC regimen (n = 52; median age, 59 years; median follow-up, 19 months) and those who received the dUCB-TCF RIC regimen (n = 39; median age, 56 years; median follow-up, 20 months) for allo-SCT between January 2007 and November 2010. There were no significant between-group differences in patient and disease characteristics. Cumulative incidences of engraftment, acute grade II-IV and chronic graft-versus-host disease were similar in the 2 groups. The median time to platelet recovery, incidence of early death (before day +100), and 2-year nonrelapse mortality were significantly higher in the dUCB-TCF group (38 days versus 0 days [P <.0001]; 20.5% versus 4% [P = .05], and 26.5% versus 6% [P = .02], respectively). The groups did not differ in terms of 2-year overall survival (62% for FB2A2-PBSC versus 61% for dUCB-TCF), disease-free survival (59% versus 50.5%), or relapse incidence (35.5% versus 23%). In multivariate analysis, the presence of a lymphoid disorder was associated with a significantly higher 2-year overall survival (hazard ratio, 0.42; 95% confidence interval, 0

    Inflammatory bowel disease (IBD) comprises two distinct but related chronic relapsing inflammatory conditions affecting different parts of the gastrointestinal tract. Crohn’s disease is characterised by a patchy transmural inflammation affecting both small and large bowel segments with several distinct phenotypic presentations. Ulcerative colitis classically presents as mucosal inflammation of the rectosigmoid (distal colitis), variably extending in a contiguous manner more proximally through the colon but not beyond the caecum (pancolitis). This article highlights aspects of the presentation, diagnosis, and management of IBD that have relevance for paediatric practice with particular emphasis on surgical considerations. Since 25% of IBD cases present in childhood or teenage years, the unique considerations and challenges of paediatric management should be widely appreciated. Conversely, we argue that the organizational separation of the paediatric and adult healthcare worlds has often resulted in late adoption of new approaches particularly in paediatric surgical practice.

    Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor occurring almost exclusively in adolescent and young adult males. The tumor is characterized by slow progression, aggressive growth, high vascularization and increased rate of persistence and recurrence. From 2000 till 2008 29 consecutive male patients with JNA Fisch grade III and IV (intracranial extradural or intradural extension) were operated in Burdenko Neurosurgical Institute (Moscow, Russia). Most patients received different kinds of treatment before admission to the Institute. All patients underwent surgical resection using predominantly orbitozygomatic approach. Preoperative endovascular embolization was applied. Total removal was achieved in 86% of cases. Postoperative complications included osteomyelitis of the bone flap (4 cases), nasal CSF leak (1 case) etc. Recurrences were observed in 3 patients, all of them underwent repeated surgeries. 4 cases are presented (3 patients with Fisch grade IV tumor and 1 with grade III). Surgical treatment is the basic tactics in management of extensive JNAs. The authors recommend to use orbitozygomatic approach and endoscopic assistance.

    ABSTRACT Objectives: To evaluate the hospital outcome and health-related quality of life (HRQOL) in adult patients admitted to intensive care units (ICUs) in Barbados. Methods: A prospective observational study was done in the medical and surgical intensive care units of the Queen Elizabeth Hospital, Barbados (QEH), to evaluate the outcomes and HRQOL in adult patients. The acute physiology and chronic health evaluation (APACHE) IV score was applied on admission to one hundred and fifty patients admitted to the ICU. The HRQOL was evaluated by using Short Form 36 (SF-36) in 63 survivors, three months after ICU discharge. Results: There was no significant difference between medical and surgical ICUs with respect to age, gender, APACHE IV scores, 90-day mortality, and length of stay. The mean (± SD) APACHE IV score was 42.6 (± 23.7). The observed mortality was 32.7% and the standardized mortality ratio (SMR) was 1.85. The APACHE IV scores were significantly higher in non-survivors compared to survivors (p < 0.001). Patients with APACHE IV of > 45, and who were ventilated in the first 24 hours had the highest mortality (66%). The mean ICU length of stay was 7.2 days. Conclusion: In this study, the SF-36 scores in all eight dimensions indicated that the HRQOL in the majority of the survivors was average or above average. There was a significant negative correlation between APACHE IV score and the SF-36 score. PMID:25781281

    Presbyopia, the gradual loss of accommodation that becomes clinically significant during the fifth decade of life, is a physiologic inevitability. Different technologies are being pursued to achieve surgical correction of this disability; however, a number of limitations have prevented widespread acceptance of surgical presbyopia correction, such as optical and visual distortion, induced corneal ectasia, haze, anisometropy with monovision, regression of effect, decline in uncorrected distance vision, and the inherent risks with invasive techniques, limiting the development of an ideal solution. The correction of the presbyopia and the restoration of accommodation are considered the final frontier of refractive surgery. The purpose of this paper is to provide an update about current procedures available for presbyopia correction, their advantages, and disadvantages. PMID:23055664

    Ease of handling and control in zero gravity and minimizing the quantity of water required were prime considerations. The program tasks include the selection of biocidal agent from among the variety used for surgical scrub, formulation of a dispensing system, test, and delivery of flight dispensers. The choice of an iodophore was based on effectiveness on single applications, general familiarity among surgeons, and previous qualification for space use. The delivery system was a choice between the squeeze foamer system and impregnated polyurethane foam pads. The impregnated foam pad was recommended because it is a simpler system since the squeeze foamer requires some applicator to effectively clean the skin surfaces, whereas the form pad is the applicator and agent combined. Testing demonstrated that both systems are effective for use as surgical scrubs.

    Postthrombotic syndrome (PTS) is a late outcome of deep vein thrombosis characterized by cramping pain, swelling, hyperpigmentation, eczema, lipodermatosclerosis, and ulceration in the leg due to increased venous outflow resistance and reflux venous flow. Newer surgical and endovascular interventions have a promising result in the management of postthrombotic syndrome. Early surgical or endovascular interventions in appropriately selected patients may decrease the incidence of recurrent ulceration and skin changes and provide a better quality of life. Duplex and IVUS (intravenous ultrasound) along with venography serve as cornerstone investigative tools for assessment of reflux and obstruction. Venous obstruction, if present, should be addressed earlier than reflux. It requires endovenous stenting, endophlebectomy, or open bypass procedures. Venous stripping, foam sclerotherapy, radiofrequency, or laser ablation are used to abolish superficial venous reflux. Valvuloplasty procedures are useful for incompetent but intact deep venous valves, while transposition or axillary vein autotransplantation is done for completely destroyed valves. PMID:22084674

    Surgical attire helps protect patients from microorganisms that may be shed from the hair and skin of perioperative personnel. The updated AORN "Guideline for surgical attire" provides guidance on scrub attire, shoes, head coverings, and masks worn in the semirestricted and restricted areas of the perioperative setting, as well as how to handle personal items (eg, jewelry, backpacks, cell phones) that may be taken into the perioperative suite. This article focuses on key points of the guideline to help perioperative personnel adhere to facility policies and regulatory requirements for attire. The key points address the potential benefits of wearing scrub attire made of antimicrobial fabric, covering the arms when in the restricted area of the surgical suite, removing or confining jewelry when wearing scrub attire, disinfecting personal items that will be taken into the perioperative suite, and sending reusable attire to a health care-accredited laundry facility after use. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures.

    2009-01-01

    Louis Pasteur (1822-1895) is considered the most notable medical scientist of his time and perhaps one of the most distinguished of all times in the history of medicine. From Dole in France to Paris, from a student of crystals to "living ferments," and from chemistry to biology and medicine, Pasteur changed the world for the benefit of humanity. The genius of Pasteur dealt with the most pressing issues of his time, basing the germ theory on the effects that microorganisms had on fermentation and putrefaction of organic matter, which gave birth to the science of bacteriology. Many other difficult problems in medicine and biology were tackled by Pasteur, culminating in the spectacular results seen with the treatment of rabies. Surgery was no exception to the scientific conquests of Pasteur. The transformation of the surgical world arose from the antiseptic concepts of Lister that were based on the germ theory of the disease, which had been derived from the germ theory of fermentation and putrefaction discovered by Pasteur. The acceptance of these principles represented the surgical revolution brought on by the science of Pasteur, a revolution that is now accepted in our daily care of surgical patients.

    Caval syndrome was diagnosed in a 4-year-old male domestic shorthair cat with severe dyspnea attributable to chylothorax. The diagnosis of heartworm infection was made on the basis of the ultrasonographic detection of a large number of adult heartworms in the right side of the heart and positive results for modified Knott's and heartworm antigen tests. Heartworms were surgically removed through an incision in the jugular vein, using a string-type horsehair brush and an alligator forceps. All clinical signs resolved after the surgery. Although treatment with agents that would kill the adult heartworms was considered, surgical treatment was used on the cat reported here. Surgical treatment may be the method of choice for use in cats with severe or persistent clinical signs attributable to infections with large numbers of heartworms.

    As few as 2 adult heartworms can cause cardiac enlargement and severe respiratory compromise in cats. Use of echocardiography to view heartworms may indicate whether surgical removal is possible. Aided by fluoroscopy, manual insertion of a catheter that contains basket-type retrieval forceps into the right atrium, via jugular venotomy, may permit removal of adult heartworms from cats. Surgical removal of heartworms and supportive treatment with heparin, prednisone, and antibiotics may result in complete recovery from heartworm infection in cats.

    Chronic osteomyelitis is refractory to nonsurgical treatment due to a resilient, infective nidus that harbors sessile, matrix-protected pathogens bound to substrate surfaces within the wound. Curative treatment mandates physical (surgical) removal of the biofilm colony, adjunctive use of antibiotics to eliminate residual phenotypes, and efforts to optimize the host response throughout therapy. Patient selection, therapeutic options, and the treatment format are determined by the Cierny/Mader staging system, while reconstruction is governed by the integrity/stability of the affected bone(s) and quality/quantity parameters of the soft-tissue envelope.

    Chronic post-surgical pain (CPSP) is a recognised adverse consequence of surgery; surgery is common, therefore the population at risk is considerable. Putative risk factors for CPSP include genetic predisposition, demographic, clinical (pain history, type of surgery, anaesthesia, acute pain severity), and psychological factors (vulnerability vs resilience). Evidence of prevention is limited: long-term benefit from pre-emptive/perioperative analgesia has not been demonstrated consistently. Large scale prospective studies with detailed pre, intra and postoperative multifactorial assessments are required to refine understanding of the aetiology and prognosis of CPSP. PMID:26526062

    In the first step of rhinoplasty, the surgical approach will expose through different types of incisions and dissection planes the osteocartilaginous framework of the nasal pyramid prior to performing actions to reduce or increase the latter. This exposure can be performed by a closed approach or by an external approach--the choice depends on the type of nose and the habits of the surgeon. Far from being opposites, closed and external approaches are complementary and should be known and mastered by surgeons performing rhinoplasty.

  11. Binge Drinking Intensity

    Background Binge drinking (≥4 drinks for women; ≥5 drinks for men, per occasion) is responsible for more than half of the estimated 80,000 U.S. deaths annually and three-quarters of the $223.5 billion in costs in 2006. Binge drinking prevalence is assessed more commonly than binge drinking intensity (i.e., number of drinks consumed per binge episode). Risk of binge drinking–related harm increases with intensity, and thus it is important to monitor. The largest number of drinks consumed is assessed in health surveys, but its usefulness for assessing binge intensity is unknown. Purpose To assess the agreement between two potential measures of binge drinking intensity: the largest number of drinks consumed by binge drinkers (maximum-drinks) and the total number of drinks consumed during their most recent binge episode (drinks-per-binge). Methods Data were analyzed from 7909 adult binge drinkers from 14 states responding to the 2008 Behavioral Risk Factor Surveillance System (BRFSS) binge drinking module. Mean and median drinks-per-binge from that module were compared to mean and median maximum-drinks. Analyses were conducted in 2010–2011. Results Mean (8.2) and median (5.9) maximum-drinks were strongly correlated with mean (7.4) and median (5.4) drinks-per-binge (r=0.57). These measures were also strongly correlated across most sociodemographic and drinking categories overall and within states. Conclusions The maximum-drinks consumed by binge drinkers is a practical method for assessing binge drinking intensity and thus can be used to plan and evaluate Community Guide–recommended strategies for preventing binge drinking (e.g., increasing the price of alcoholic beverages and regulating alcohol outlet density).

    In general, university-based global health initiatives have tended to focus on expanding access to primary care. In the past, surgical programs may have been characterized by sporadic participation with little educational focus. However, there have been some notable exceptions with plastic surgery volunteer missions. We offer another model of regularly scheduled surgical trips to rural Haiti in plastic and general surgery. The goal of these trips is to reduce the burden of surgical disease and ultimately repair every cleft lip/palate in Haiti. Another principal objective is to accelerate the training of American residents through increased case load and personal interaction with attending surgeons in a concentrated period. Diversity of the case load and the overall number of surgeries performed by residents in a typical surgical trip outpaces the experiences available during a typical week in an American hospital setting. More importantly, we continue to provide ongoing training to Haitian nurses and surgeons in surgical techniques and postoperative care. Our postoperative complication rate has been relatively low. Our follow-up rates have been lower than 70% despite intensive attempts to maintain continued communication with our patients. Through our experiences in surgical care in rural Haiti, we were able to quickly ramp up our trauma and orthopedic surgical care immediately after the earthquake. Project Medishare and the University of Miami continue to operate a trauma and acute care hospital in Port au Prince. The hospital provides ongoing orthopedic, trauma, and neurosurgical expertise from the rotating teams of American surgeons and training of Haitian surgeons in modern surgical techniques. We believe that surgical residencies in the United States can improve their training programs and reduce global surgical burden of disease through consistent trips and working closely with country partners.

    In 2013, a total of 84,332 patients had undergone extracapsular tonsillectomies (TE) and 11,493 a tonsillotomy (TT) procedure in Germany. While the latter is increasingly performed, the number of the former is continually decreasing. However, a constant number of approximately 12,000 surgical procedures in terms of abscess-tonsillectomies or incision and drainage are annually performed in Germany to treat patients with a peritonsillar abscess. The purpose of this part of the clinical guideline is to provide clinicians in any setting with a clinically focused multi-disciplinary guidance through the surgical treatment options to reduce inappropriate variation in clinical care, improve clinical outcome and reduce harm. Surgical treatment options encompass intracapsular as well as extracapsular tonsil surgery and are related to three distinct entities: recurrent episodes of (1) acute tonsillitis, (2) peritonsillar abscess and (3) infectious mononucleosis. Conservative management of these entities is subject of part I of this guideline. (1) The quality of evidence for TE to resolve recurrent episodes of tonsillitis is moderate for children and low for adults. Conclusions concerning the efficacy of TE on the number of sore throat episodes per year are limited to 12 postoperative months in children and 5-6 months in adults. The impact of TE on the number of sore throat episodes per year in children is modest. Due to the heterogeneity of data, no firm conclusions on the effectiveness of TE in adults can be drawn. There is still an urgent need for further research to reliably estimate the value of TE compared to non-surgical therapy of tonsillitis/tonsillo-pharyngitis. The impact of TE on quality of life is considered as being positive, but further research is mandatory to establish appropriate inventories and standardized evaluation procedures, especially in children. In contrast to TE, TT or comparable procedures are characterized by a substantially lower postoperative

  14. Surgical Scar Revision: An Overview

    2014-01-01

    Scar formation is an inevitable consequence of wound healing from either a traumatic or a surgical intervention. The aesthetic appearance of a scar is the most important criteria to judge the surgical outcome. An understanding of the anatomy and wound healing along with experience, meticulous planning and technique can reduce complications and improve the surgical outcome. Scar revision does not erase a scar but helps to make it less noticeable and more acceptable. Both surgical and non-surgical techniques, used either alone or in combination can be used for revising a scar. In planning a scar revision surgeon should decide on when to act and the type of technique to use for scar revision to get an aesthetically pleasing outcome. This review article provides overview of methods applied for facial scar revision. This predominantly covers surgical methods. PMID:24761092

    After the diagnosis of transsexuality is well definated and recognized in most western countries, the surgical transformation of the genital area is performed. Before surgical treatment an exact psychiatric clarification is absolutely essential. The operation is the last part of a long treatment. The surgical result in the more common female transsexual is quite reasonable. The treatment of the fewer male transsexuals is not solved completely, especially the reliable techniques for penis reconstructions are not very sufficient.

    Neuronavigation and stereotaxy are techniques designed to help neurosurgeons precisely localize different intracerebral pathological processes by using a set of preoperative images (CT, MRI, fMRI, PET, SPECT etc.). The development of computer assisted surgery was possible only after a significant technological progress, especially in the area of informatics and imagistics. The main indications of neuronavigation are represented by the targeting of small and deep intracerebral lesions and choosing the best way to treat them, in order to preserve the neurological function. Stereotaxis also allows lesioning or stimulation of basal ganglia for the treatment of movement disorders. These techniques can bring an important amount of confort both to the patient and to the neurosurgeon. Neuronavigation was introduced in Romania around 2003, in four neurosurgical centers. We present our five-years experience in neuronavigation and describe the main principles and surgical techniques.

There is a 4-year training period during which residents in their third year spend 4 months as the sole surgeon in a rural community. During the senior year they are entitled to an elective period in a place of their choosing. After completion of the 4 years, residents have to present a thesis and undergo an oral examination before getting a university diploma. They are then encouraged to pass the written and oral examination of the Mexican Board of Surgery before they are fully certified to enter practice in a public or private hospital. PMID:19603225

    2015-02-01

    Adult flatfoot is defined as a flattening of the medial arch of the foot in weight-bearing and lack of a propulsive gait. The 3 lesion levels are the talonavicular, tibiotarsal and midfoot joints. The subtalar joint is damaged by the consequent rotational defects. Clinical examination determines deformity and reducibility, and assesses any posterior tibialis muscle deficit, the posterior tibialis tendon and spring ligament being frequently subject to degenerative lesions. Radiographic examination in 3 incidences in weight-bearing is essential, to determine the principal level of deformity. Tendon (posterior tibialis tendon) and ligamentous lesions (spring ligament and interosseous ligament) are analyzed on MRI or ultrasound. In fixed deformities, CT explores for arthritic evolution or specific etiologies. 3D CT reconstruction can analyze bone and joint morphology and contribute to the planning of any osteotomy. Medical management associates insoles and physiotherapy. Acute painful flatfoot requires strict cast immobilization. Surgical treatment associates numerous combinations of procedures, currently under assessment for supple flatfoot: for the hindfoot: medial slide calcaneal osteotomy, calcaneal lengthening osteotomy, or arthroereisis; for the midfoot: arthrodesis on one or several rays, or first cuneiform or first metatarsal osteotomy; for the ankle: medial collateral ligament repair with tendon transfer. Fixed deformities require arthrodesis of one or several joint-lines in the hindfoot; for the ankle, total replacement after realignment of the foot, or tibiotalocalcaneal fusion or ankle and hindfoot fusion; and, for the midfoot, cuneonavicular or cuneometatarsal fusion. Tendinous procedures are often associated. Specific etiologies may need individualized procedures. In conclusion, adult flatfoot tends to be diagnosed and managed too late, with consequent impact on the ankle, the management of which is complex and poorly codified.

    In the last century remarkable advances have been made in surgery, associated with the lowest recorded rates of infection or sepsis. Many surgical practices are time honoured but have little scientific basis to prevent postoperative infection whereas some local and systemic factors are well recognized and can be modified to lower infection risks. Surgical skill is not easily measurable but shorter operations in experienced hands leaving the minimum of tissue damage, haematoma or dead space have the lowest infection rates in general surgery: < 2% in clean and < 10% in contaminated operations. Adequate surgical scrub, appropriate suture materials and antibiotic prophylaxis, perioperative correction of dehydration and poor nutrition are examples of effective therapy which can be conformed to by all surgeons. Other factors, such as the use of wound guards, drains and surgical dressings are less easy to estimate for effectiveness or be sure that they could be changed or left out of surgical ritual.

    Surgical procedures for voice restoration serve to improve oral communication by better vocal function. They comprise of phonomicrosurgery, with direct and indirect access to the larynx; laryngoplasty; laryngeal injections; and surgical laryngeal reinnervation. The basis for modern surgical techniques for voice disorders is the knowledge about the ultrastructure of the vocal folds and the increasing experience of surgeons in voice surgery, while facing high social and professional demands on the voice. Vocal activity limitation and participation restriction has become more important in the artistic and social areas. A number of surgical methods that have been developed worldwide for this reason, are presented in this article. Functional oriented surgery has to meet high standards. The diagnostics of vocal function has to be multi-dimensional in order to determine the indication and the appropriate surgical intervention. PMID:22073062

    The development progress of a precision electro-mechanical instrument which allows the detection and documentation of the forces and moment applied to human tissue during surgery (under actual operation room conditions), is reported. The pen-shaped prototype probe which measures 1/2 inch in diameter and 7 inches in length was fabricated using an aerodynamic balance. The aerodynamic balance, a standard wind tunnel force and moment sensing transducer, measures the forces and the moments transmitted through the surgeon's hand to the human tissue during surgery. The prototype probe which was fabricated as a development tool was tested successfully. The final version of the surgical force detection probe will be designed based on additional laboratory tests in order to establish the full scale loads. It is expected that the final product will require a simplified aerodynamic balance with two or three force components and one moment component with lighter full scale loads. A signal conditioner was fabricated to process and display the outputs from the prototype probe. This unit will be interfaced with a PC-based data system to provide automatic data acquisition, data processing, and graphics display. The expected overall accuracy of the probe is better than one percent full scale.

  9. Oncogenes and surgical pathology.

    PubMed

    Bartow, S A

    1987-08-01

    The discovery of oncogenes began with identification of genetic material in viruses capable of causing neoplasia in animals. Through processes of "transduction" and "insertional mutagenesis," RNA/retroviruses may (1) alter directly, (2) alter expression of, or (3) move pieces of host cellular genome in ways that they become potential agents of neoplastic transformation. The pieces of host cellular genome, either affected in situ by viral gene insertion or transduced by the virus, are known as oncogenes. Approximately 20 oncogenes have been identified. Although they have yet to be proven to be sufficient or necessary for neoplastic transformation, the evidence for their playing a part in the transformation process is mounting. The functions of the protein products of the various oncogenes are closely related to those of proteins involved in normal cell regulatory and cycle activities. Study of the oncogene products and their functions serves to elucidate the basic character of neoplasia. The functional classes of oncogenes with specific examples of genomic amplification, altered mRNA or protein product expression, or mutational deletion associated with human neoplasia are reviewed herein. Since the techniques for detecting oncogene DNA and mRNA alterations are rapidly becoming a part of our diagnostic armamentarium, surgical pathologists should be prepared for the imminent use of such molecular techniques and information in diagnosis and prognosis of human neoplasia.

    Surgical gloves are used by healthcare workers to protect them against bloodborne pathogens and other potential infectants and to prevent wound contamination in patients. In response to the increasing prevalence of allergies to natural rubber latex (NRL) among patients and medical staff, the trend toward purchasing gloves made of synthetic materials is on the rise. However, latex continues to dominate the market, and some people still perceive synthetic gloves as providing less protection and being less comfortable than NRL gloves. For this Update Evaluation, we present our findings for three newly evaluated glove models from three manufacturers and summarize our findings for the seven previously evaluated models that are still on the market. (Our earlier Evaluation was published in the February-March 2000 Health Devices.) As in the previous Evaluation, our ratings are based on the gloves' barrier effectiveness--that is, their resistance to viral penetration and their durability--and comfort. We also compared these characteristics of the synthetic gloves to those of NRL gloves. We found that all the evaluated gloves offer adequate barrier protection but that their level of comfort varies considerably. We rate three models Preferred, five models Acceptable, and two models Not Recommended. PMID:12116503

    Background Costs of care in high-procedure hospitals may be related to factors beyond procedures. We sought to determine how costs for patients with heart failure (HF) not receiving procedures compare between hospital groups defined by their overall use of procedures. Methods and Results We identified all 2009–2010 adult HF hospitalizations in hospitals capable of performing invasive procedures that had at least 25 HF hospitalizations in the Perspective® database from Premier, Inc. We divided hospitals into 2 groups by the proportion of HF patients receiving invasive percutaneous or surgical procedures: low (>0–10%) and high (at least 10%). The standard costs of hospitalizations at each hospital were risk adjusted using patient demographics and comorbidities. We used the Wilcoxon Rank Sum test to assess cost, length of stay, and mortality outcome differences between the 2 groups. Median risk-standardized standard costs among low-procedural HF hospitalizations were $5,259 ($4,683, $6,814) versus $6,965 ($5,981, $8,235) for hospitals with high procedure use (p<0.001). Median length of stay was 4 days for both groups. Risk-standardized mortality rates were 5.4% (low-procedure) and 5.0% (high-procedure) (p=0.009). We did not identify any single service area that explained the difference in costs between hospital groups, but these hospitals had higher costs for most service areas. Conclusion Among patients who do not receive invasive procedures, the cost of HF hospitalization is higher in more procedure-intense hospitals compared with hospitals that perform fewer procedures.

    Surgical intervention is an integral component in the diagnosis and management of mycetoma. Surgical treatment is indicated for small, localised lesions and massive lesions to reduce the mycetoma load and to enable better response to medical therapy. It is also a life-saving procedure in patients with massive disease and sepsis. Surgical options for mycetoma treatment range from a wide local surgical excision to repetitive debridement excisions to amputation of the affected part. Adequate anaesthesia, a bloodless field, wide local excision with adequate safety margins in a suitable surgical facility, and expert surgeons are mandatory to achieve the best surgical outcome. Surgical intervention in mycetoma is associated with considerable morbidity, deformities, and disabilities, particularly in advanced disease. These complications can be reduced by educating patients to seek medical advice earlier when the lesion is small, localised, and amenable to surgery. There is no evidence for mycetoma hospital cross infection. This communication is based on the authors’ experience in managing over 7,200 mycetoma patients treated at the Mycetoma Research Centre, University of Khartoum, Sudan. PMID:27336736

    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).

    During the Great War, the French surgeon Alexis Carrel, in collaboration with the English chemist Henry Dakin, devised an antiseptic treatment for infected wounds. This paper focuses on Carrel’s attempt to standardise knowledge of infected wounds and their treatment, and looks closely at the vision of surgical skill he espoused and its difference from those associated with the doctrines of scientific management. Examining contemporary claims that the Carrel–Dakin method increased rather than diminished demands on surgical work, this paper further shows how debates about antiseptic wound treatment opened up a critical space for considering the nature of skill as a vital dynamic in surgical innovation and practice.

    A study comparing the relative efficacy of a five versus a ten minute surgical scrub was carried out using random sampling of personnel scrubbing for routine scheduled hospital surgical procedures. Scrubbing for five minutes was found to be equally as effective as scrubbing for ten minutes. Betadine was compared to pHisoHex as a scrubbing agent and found to be statistically more effective in degerming the skin following a five minute scrub. As a result of this study, a routine preoperative surgical scrub of five minutes' duration, using Betadine as the scrubbing agent, is recommended.

    Primary surgical treatment should be considered for patients with metastatic melanoma. Because of the poor response of melanoma to chemotherapy or radiation therapy, surgery can be the best approach to quickly eliminate detectable disease and return the patient to normal activities. In properly selected patients, surgery can lead to significant palliation and prolongation of survival. This article reviews the principles of patient selection and the potential benefits of surgical management of melanoma metastatic to various sites. Novel adjuvant therapies are being developed to augment the benefits of surgical treatment of advanced melanoma in the future.

    During the Great War, the French surgeon Alexis Carrel, in collaboration with the English chemist Henry Dakin, devised an antiseptic treatment for infected wounds. This paper focuses on Carrel's attempt to standardise knowledge of infected wounds and their treatment, and looks closely at the vision of surgical skill he espoused and its difference from those associated with the doctrines of scientific management. Examining contemporary claims that the Carrel-Dakin method increased rather than diminished demands on surgical work, this paper further shows how debates about antiseptic wound treatment opened up a critical space for considering the nature of skill as a vital dynamic in surgical innovation and practice.

    Surgical wound infection is an important outcome indicator in the postoperative period. A 3-year prospective cohort epidemiological study of 2202 surgical patients from seven surgical wards across two hospitals was carried out using gold standard surveillance methodology. This involved following patients up as inpatients and postdischarge surveillance to 30 days by an independent observer. The results led to the development of a mathematical model for risk of clean, elective surgical wound infection. Risk of surgical wound infection was increased by smoking, higher body mass index, presence of malignancy, haematoma formation, increasing numbers of people in theatre, adherent dressing usage, and higher times to suture removal (P<0.05). The results show that this type of surveillance is an effective way of collecting accurate data on wound infection rates. It was noted that patient care practices affected the surgical wound infection rate and the surveillance was used to facilitate the adoption of evidence-based practice, through recommendations for clean surgery, to reduce the risk from extrinsic risk factors for wound infection. As a result of the implementation of this evidence-based practice there was a significant reduction (P<0.05) in the clean wound infection rate.

    This paper describes work in progress on the design and development of a prototype simulator for minimally invasive otolaryngology surgical training. The anatomy of the paranasal sinuses is geometrically complex and dangerously close to the brain and orbits, making this procedure challenging to practice and difficult to learn. We discuss the potential role of computer simulation to enhance and accelerate acquisition of surgical skills. The design goals of the prototype include high-fidelity simulation of the endoscopic imagery and haptic cues of surgical palpation. The prototype enables endoscopic navigation and limited interactive tissue manipulation and dissection tasks on a virtual patient using realistic replicas of surgical tools. We present an overview of the system architecture with a discussion of the technological challenges, design issues and current status of the efforts.

    Third nerve paralysis has been known to be associated with a wide spectrum of presentation and other associated factors such as the presence of ptosis, pupillary involvement, amblyopia, aberrant regeneration, poor bell's phenomenon, superior oblique (SO) overaction, and lateral rectus (LR) contracture. Correction of strabismus due to third nerve palsy can be complex as four out of the six extraocular muscles are involved and therefore should be approached differently. Third nerve palsy can be congenital or acquired. The common causes of isolated third nerve palsy in children are congenital (43%), trauma (20%), inflammation (13%), aneurysm (7%), and ophthalmoplegic migraine. Whereas, in adult population, common etiologies are vasculopathic disorders (diabetes mellitus, hypertension), aneurysm, and trauma. Treatment can be both nonsurgical and surgical. As nonsurgical modalities are not of much help, surgery remains the main-stay of treatment. Surgical strategies are different for complete and partial third nerve palsy. Surgery for complete third nerve palsy may involve supra-maximal recession - resection of the recti. This may be combined with SO transposition and augmented by surgery on the other eye. For partial third nerve, palsy surgery is determined according to nature and extent of involvement of extraocular muscles. PMID:27433033

    2011-04-01

    Fibrodysplasia (or Myositis) Ossificans Progressiva (FOP) is a rare genetic disease with variable expression, characterized by the association of congenital anomalies of the toes and fingers and progressive appearance of ectopic bone within the skeletal muscles, often following a trauma or an infection. FOP initially affects the nape and thoracic paravertebral muscles. With age, there is a progression of ossifications to other muscular groups following a proximodistal and cranio-caudal extension. Patients develop a restrictive respiratory insufficiency with atelectasis. The diagnosis of FOP is clinical and does not require biopsy. Circumscribed post-traumatic ossifying myositis is the most important differential diagnosis. It is characterized by the appearance of painful ossifications, in young adults, following a trauma and is limited to one localisation. The conservative treatment of FOP remains unsatisfactory. Surgical removal of osteomas to restore joint mobility leads to the development of additional heterotopic ossifications. Each surgical attempt brings about a quasi-inevitable recurrence. Anaesthesia of patients with FOP is difficult because of spinal rigidity and ankylosis of the jaw. Surgery is indicated only with a focused indication to correct an invalidating deformity.

A 65 year-old male, without previous hepatopathy, who consulted due to right hypochondrial pain with a subacute evolution. The pathological diagnosis was adult epithelial hepatoblastoma, with free surgical margins. The patient recei-ved a second surgical intervention 5 months later due to early recurrence and died 10 months after the diagnosis due to a new massive recurrence. His definitive diagnosis is histological. Radical surgery is the only treatment that increases survival, but recurrence is frequent. There are no well-defined patterns of adjuvant chemotherapy nor is there any trans-plant experience. PMID:27599957

  1. The Varicocele: Clinical Presentation, Evaluation, and Surgical Management.

    2016-09-01

    A varicocele is an abnormal dilatation and tortuosity of the veins of the spermatic cord. Although varicoceles are common in the general population and are frequently found on routine physical examinations, they represent the most common correctable cause of male factor infertility. Varicoceles are also often incidental findings on imaging studies, particularly scrotal ultrasound. Importantly, not all varicoceles should be treated equally (or at all), and basic guidelines on the evaluation and indications for treatment of adult varicoceles should be reviewed before counseling and treatment. A semen analysis should be obtained for any male patient of reproductive age considering intervention. The adolescent varicocele is managed much differently than the adult varicocele and remains a source of controversy. This review describes the clinical presentation and the evaluation of adult and pediatric varicoceles, and provides guidance on their diagnosis and workup. It also describes options for surgical repair and the success and complication rates associated with each surgical approach, ultimately supporting microsurgical subinguinal varicocele repair as the current surgical standard.

  2. Metabolism and nutritional support in the surgical neonate.

    PubMed

    Various factors can influence the metabolism of surgical neonates. These include prematurity, operative stress, critical illness, and sepsis. The nutritional management of surgical infants with congenital or acquired intestinal abnormalities has improved after the introduction of parenteral nutrition. This article is focused on the energy and protein metabolism of surgical neonates with particular reference to the metabolic response to operative trauma and sepsis. The metabolic utilization of intravenous nutrients also is discussed. The metabolic response to operative trauma is different between neonates and adults. Infants have high rates of protein turnover and are avid retainers of nitrogen. Energy expenditure increases only transiently (4 to 6 hours) after major surgery in neonates. Protein turnover and catabolism seems not to be affected by major operative procedures in neonates. In neonates on parenteral nutrition, carbohydrate and fat have an equivalent effect on protein metabolism. The main determinants of fat utilization are carbohydrate intake and resting energy expenditure. Parenteral nutrition in surgical neonates is associated with increased production of oxygen-free radicals. This seems to be related to intravenous fat administration. Promoting fat utilization by reducing the carbohydrate to fat ratio in the intravenous diet reduces free radical activity to a similar extent as fat exclusion. Glutamine appears to be safe for use in neonates and infants and is "conditionally essential" in very-low birth weight infants and in septic neonates. Enteral glutamine supplementation in very-low birth weight infants reduces the risk of sepsis. The metabolism of surgical neonates is affected by operative trauma, critical illness, and sepsis. Nutritional support in surgical neonates has a profound impact on outcome. Exogenous glutamine can modulate immune, metabolic, and inflammatory responses. Further investigations are needed to clarify the clinical benefit of

    Congenital hyperinsulinism is a functional disorder of insulin secretion. In its diffuse severe form, it is traditionally treated with over 95% pancreatectomy. However, even after this procedure normoglycemia is not always achieved. Non-surgical therapy with frequent or continuous feeding, medication and close monitoring is another alternative. In this review we compare the two approaches to this condition focusing on early complications, diabetes, neurological outcome and home management issues. Early complications of pancreatectomy include mechanical, metabolic and infectious complications. Non-surgical interventions can be complicated by unwarranted effects of medications and of invasive procedures. Diabetes occurs with both approaches but much less frequently and years later with non-surgical treatment. Regarding neurodevelopmental outcome, most data come from heterogeneous groups. Nevertheless, it appears that outcome is not adversely affected by avoiding surgery. Home management is far more difficult for the non-surgical form. When the non-surgical approach is successful in achieving normoglycemia and parents are highly motivated, this mode of therapy should be considered.

    Retrospective analysis of the treatment results of 120 patients, suffering solitary hepatic abscess (SHA), was conducted. The sanation methods, in accordance to technology, the treatment impact intensity and aggressiveness, may be divided on three lines: aspirational, draining and resectional. The method of sanation is selected on the background of morphological peculiarities of abscess--its sizes, by presence of sequesters, divisioning septs, dense rigid capsule, grade of periprocess. Surgical access is determined by the abscess localization, the patient's state severity, instrumental equipment of the clinic. Differentiated approach, taking into account genesis, sizes, localization and stage of its formation, constitutes a background of successful treatment of SHA. In totally formatted acute SHA, as a rule, the methods of choice are aspirational and aspiration-draining methods of sanation under ultrasonographic control or laparoscopy. In the presence of chronic SHA or suppurated parasitic hepatic cyst it is mandatory to select the resectional methods.

    Adult scoliosis is a complex three-dimensional rotational deformity of the spine, resulting from the progressive degeneration of the vertebral elements in middle age, in a previously straight spine; a Cobb angle greater than 10° in the coronal plane, which also alters the sagittal and axial planes. It originates an asymmetrical degenerative disc and facet joint, creating asymmetrical loads and subsequently deformity. The main symptom is axial, radicular pain and neurological deficit. Conservative treatment includes drugs and physical therapy. The epidural injections and facet for selectively blocking nerve roots improves short-term pain. Surgical treatment is reserved for patients with intractable pain, radiculopathy and/ or neurological deficits. There is no consensus for surgical indications, however, it must have a clear understanding of the symptoms and clinical signs. The goal of surgery is to decompress neural elements with restoration, modification of the three-dimensional shape deformity and stabilize the coronal and sagittal balance. PMID:27012088

    Abstract The aim of the present article was to systematically review the ethics of surgical innovation and introduce the components of the learning health care system to guide future research and debate on surgical innovation. Although the call for evidence-based practice in surgery is increasingly high on the agenda, most surgeons feel that the format of the randomized controlled trial is not suitable for surgery. Innovation in surgery has aspects of, but should be distinguished from both research and clinical care and raises its own ethical challenges. To answer the question “What are the main ethical aspects of surgical innovation?”, we systematically searched PubMed and Embase. Papers expressing an opinion, point of view, or position were included, that is, normative ethical papers. We included 59 studies discussing ethical aspects of surgical innovation. These studies discussed 4 major themes: oversight, informed consent, learning curve, and vulnerable patient groups. Although all papers addressed the ethical challenges raised by surgical innovation, surgeons hold no uniform view of surgical innovation, and there is no agreement on the distinction between innovation and research. Even though most agree to some sort of oversight, they offer different alternatives ranging from the formation of new surgical innovation committees to establishing national registries. Most agree that informed consent is necessary for innovative procedures and that surgeons should be adequately trained to assure their competence to tackle the learning curve problem. All papers agree that in case of vulnerable patients, alternatives must be found for the informed consent procedure. We suggest that the concept of the learning health care system might provide guidance for thinking about surgical innovation. The underlying rationale of the learning health care system is to improve the quality of health care by embedding research within clinical care. Two aspects of a learning health

    In this article, we discuss the development of methods for computer-aided jaw surgery, which allows us to incorporate the high level of precision necessary for transferring virtual plans into the operating room. We also present a complete computer-aided surgery system developed in close collaboration with surgeons. Surgery planning and simulation include construction of 3-dimensional surface models from cone-beam computed tomography, dynamic cephalometry, semiautomatic mirroring, interactive cutting of bone, and bony segment repositioning. A virtual setup can be used to manufacture positioning splints for intraoperative guidance. The system provides further intraoperative assistance with a computer display showing jaw positions and 3-dimensional positioning guides updated in real time during the surgical procedure. The computer-aided surgery system aids in dealing with complex cases with benefits for the patient, with surgical practice, and for orthodontic finishing. Advanced software tools for diagnosis and treatment planning allow preparation of detailed operative plans, osteotomy repositioning, bone reconstructions, surgical resident training, and assessing the difficulties of the surgical procedures before the surgery. Computer-aided surgery can make the elaboration of the surgical plan a more flexible process, increase the level of detail and accuracy of the plan, yield higher operative precision and control, and enhance documentation of cases.

    Background Surgery is increasingly recognized as an important driver for health systems strengthening, especially in developing countries. To facilitate quality improvement initiatives, baseline knowledge of capacity for surgical, anaesthetic, emergency and obstetric care is critical. In partnership with the Malawi Ministry of Health, we quantified government hospitals’ surgical capacity through workforce, infrastructure and health service delivery components. Methods From November 2012 to January 2013, we surveyed district and mission hospital administrators and clinical staff onsite using a modified version of the Personnel, Infrastructure, Procedures, Equipment and Supplies (PIPES) tool from Surgeons OverSeas. We calculated percentage of facilities demonstrating adequacy of the assessed components, surgical case rates, operating theatre density and surgical workforce density. Results Twenty-seven government hospitals were surveyed (90% of the district hospitals, all central hospitals). Of the surgical workforce surveyed (n = 370), 92.7% were non-surgeons and 77% were clinical officers (COs). Of the 109 anaesthesia providers, 95.4% were non-physician anaesthetists (anaesthesia COs or ACOs). Non-surgeons and ACOs were the only providers of surgical services and anaesthetic services in 85% and 88.9% of hospitals, respectively. No specialists served the district hospitals. All of the hospitals experienced periods without external electricity. Most did not always have a functioning generator (78.3% district, 25% central) or running water (82.6%, 50%). None of the district hospitals had an Intensive Care Unit (ICU). Cricothyroidotomy, bowel resection and cholecystectomy were not done in over two-thirds of hospitals. Every hospital provided general anaesthesia but some did not always have a functioning anaesthesia machine (52.2%, 50%). Surgical rate, operating theatre density and surgical workforce density per 100 000 population was 289.48–747.38 procedures, 0

    Background Convergence insufficiency is a common eye muscle co-ordination problem in which the eyes have a strong tendency to drift outward (exophoria) when reading or doing close work. Symptoms may include eye strain, headaches, double vision, print moving on the page, frequent loss of place when reading, inability to concentrate, and short attention span. Objectives To systematically assess and synthesize evidence from randomized controlled trials (RCTs) on the effectiveness of non-surgical interventions for convergence insufficiency. Search strategy We searched The Cochrane Library, MEDLINE, EMBASE, Science Citation Index, the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) and ClinicalTrials.gov (www.clinicaltrials.gov) on 7 October 2010. We manually searched reference lists and optometric journals. Selection criteria We included RCTs examining any form of non-surgical intervention against placebo, no treatment, sham treatment, or each other. Data collection and analysis Two authors independently assessed eligibility, risk of bias, and extracted data. We performed meta-analyses when appropriate. Main results We included six trials (three in children, three in adults) with a total of 475 participants. We graded four trials at low risk of bias. Evidence from one trial (graded at low risk of bias) suggests that base-in prism reading glasses was no more effective than placebo reading glasses in improving clinical signs or symptoms in children. Evidence from one trial (graded at high risk of bias) suggests that base-in prism glasses using a progressive addition lens design was more effective than progressive addition lens alone in decreasing symptoms in adults. At three weeks of therapy, the mean difference in Convergence Insufficiency Symptoms Survey (CISS) score was −10.24 points (95% confidence interval (CI) −15.45 to −5.03). Evidence from two trials (graded at low risk of bias) suggests that outpatient (or office-based as used in the

    The methods proposed for managing fluids and particulate debris during minor surgery on Space Station Freedom (SSF) were investigated and demonstrated. A KC-135 parabolic flight test was performed, in which the flight followed the standard 40 parabola profile with 20 to 25 seconds in near-zero gravity in each parabola. The equipment (suction and laminar flow device) was evaluated. While this equipment performed satisfactorily previously in the dental simulation, the purpose of the current flight was to reconfigure the equipment in support of a minor surgical situation in order to evaluate its efficacy and establish clear requirements for the actual flight hardware. To accomplish the study the Health Maintenance Facility medical restraint system was deployed as for surgical use and mannequin suture arm was restrained to its surface. The surgical area was established as for performing minor surgery with standard tray and suture instruments employed.

  17. Surgical treatment of facial paralysis.

    2009-03-01

    The management of facial paralysis is one of the most complex areas of reconstructive surgery. Given the wide variety of functional and cosmetic deficits in the facial paralysis patient, the reconstructive surgeon requires a thorough understanding of the surgical techniques available to treat this condition. This review article will focus on surgical management of facial paralysis and the treatment options available for acute facial paralysis (<3 weeks duration), intermediate duration facial paralysis (3 weeks to 2 yr) and chronic facial paralysis (>2 yr). For acute facial paralysis, the main surgical therapies are facial nerve decompression and facial nerve repair. For facial paralysis of intermediate duration, nerve transfer procedures are appropriate. For chronic facial paralysis, treatment typically requires regional or free muscle transfer. Static techniques of facial reanimation can be used for acute, intermediate, or chronic facial paralysis as these techniques are often important adjuncts to the overall management strategy.

    Chronic pancreatitis is a progressive inflammatory disease resulting in permanent structural damage of the pancreas. It is mainly characterized by recurring epigastric pain and pancreatic insufficiency. In addition, progression of the disease might lead to additional complications, such as pseudocyst formation or development of pancreatic cancer. The medical and surgical treatment of chronic pancreatitis has changed significantly in the past decades. With regard to surgical management, pancreatic head resection has been shown to be a mainstay in the treatment of severe chronic pancreatitis because the pancreatic head mass is known to trigger the chronic inflammatory process. Over the years, organ-preserving procedures, such as the duodenum-preserving pancreatic head resection and the pylorus-preserving Whipple, have become the surgical standard and have led to major improvements in pain relief, preservation of pancreatic function, and quality of life of patients.

    Parasitic infestation is common in developing countries especially in Africa. Children are often more vulnerable to these infections. Many health problems result from these infestations, including malnutrition, iron-deficiency anemia, surgical morbidities, and even impaired cognitive function and educational achievement. Surgical intervention may be needed to treat serious complications caused by some of these parasites. Amoebic colitis and liver abscess caused by protozoan infections; intestinal obstruction, biliary infestation with cholangitis and liver abscess, and pancreatitis caused by Ascaris lumbricoides; biliary obstruction caused by Faschiola; hepatic and pulmonary hydatid cysts caused by Echinococcus granulosus and multilocularis are examples. Expenditure of medical care of affected children may cause a great burden on many African governments, which are already suffering from economic instability. The clinical presentation, investigation, and management of some parasitic infestations of surgical relevance in African children are discussed in this article.

    Fecal incontinence is a socially debilitating condition that can lead to social isolation, loss of self-esteem and self-confidence, and depression in an otherwise healthy person. After the appropriate clinical evaluation and diagnostic testing, medical management is initially instituted to treat fecal incontinence. Once medical management fails, there are a few surgical procedures that can be considered. This article is devoted to the various surgical options for fecal incontinence including the history, technical details, and studies demonstrating the complication and success rate. PMID:25320569

    Implant placement has become a routine modality of dental care.Improvements in surgical reconstructive methods as well as increased prosthetic demands,require a highly accurate diagnosis, planning and placement. Recently,computer-aided design and manufacturing have made it possible to use data from computerised tomography to not only plan implant rehabilitation,but also transfer this information to the surgery.A review on one of this technique called Stereolithography is presented in this article.It permits graphic and complex 3D implant placement and fabrication of stereolithographic surgical templates. Also offers many significant benefits over traditional procedures. PMID:24179955

    The transanal approach for rectal resection is a promising approach, because it increases the circumferential radial margin, especially for difficult cases. Meanwhile, functional sequelae are frequent after rectal cancer surgery and are often due to neurological lesions. There is little literature describing surgical anatomy from bottom to top. We combined our surgical experience with our fetal and adult anatomical research to provide a bottom-up surgical description focusing on neurological anatomy (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A148).

    Trapdoor fractures occur almost exclusively in the pediatric population. The authors describe an adult with an entrapped inferior rectus muscle sheath in a trapdoor fracture. A 37-year-old man presented with persistent diplopia 3 weeks after blunt right orbital trauma. The only abnormal findings on clinical examination were limited vertical ductions. No bony defect or displacement was evident on CT. However, several small pockets of air were visible adjacent to the inferior rectus muscle. On surgical exploration, a linear nondisplaced orbital floor fracture was confirmed, and the entrapped inferior rectus muscle was released. One month postoperatively, extraocular motility had improved with no diplopia in primary or reading positions. This case demonstrates that trapdoor fractures can occur in adults and should be considered when suggestive findings are encountered. Clinicians should be aware of this because timely diagnosis and treatment might achieve more favorable outcomes.

    1997-10-01

    The buried penis is a rare congenital entity, whose treatment is surgical. There are few publications concerning this matter. The authors report on their experience in 10 cases (1990-1995). In this abnormality, the tip of the glans does not project from the pubic or scrotal skin. It is due to: 1) an excessive development of the penile fascia which retracts the penis; 2) insufficient attachment of the penile skin at the base of the penis; 3) often excessive prepubic fat worsens the appearance of the abnormality but does not by itself totally explain it; 4) a tight phimosis is often present. Surgical treatment is necessary because this aspect tends to persist even after puberty. One cannot indeed count on the development at the age of puberty, neither on the diminution of the fat, nor on the simple cure of the phimosis. One must above all ban circumcision which causes the risk of eliminating the skin necessary for reconstruction. The surgical procedure will comprise: 1) a longitudinal dorsal incision extended circumferentially; 2) resection of the thickened fascia penis; 3) anchoring of the deep face of the dermis to the proximal part of the fascia penis at the base of the penis. This surgical procedure has always brought a significant improvement to the appearance of the penis.

    Despite publishing surgical outcomes being a positive step forwards in the progression of England's healthcare system, it has no doubt been faced with criticism and reservations. This review article aims to discuss the pros and cons of publishing individual surgical outcomes, as well as the challenges faced. Publishing outcomes requires data from a number of sources such as national clinical audits, hospital episode statistics, patient-reported outcomes, registers and information from revalidation. As yet, eight surgical specialties have begun publishing their data, including cardiac (coronary artery bypass graft, valve and aortic surgery), endocrine (thyroidectomy, lobectomy, isthmusectomy), orthopaedic (hip and knee replacement), urological (full and partial nephrectomies, nephroureterectomy), colorectal (bowel tumour removal), upper gastrointestinal (stomach cancer and oesophageal cancer removal, bariatric surgery), ear, nose and throat surgery (larynx, oral cavity, oropharynx, hypopharynx and salivary gland cancer removal), as well as vascular surgery (abdominal aortic aneurysm, carotid endarterectomy). However, not all procedures have been addressed. Despite the controversy surrounding the topic of publishing surgical outcomes, the advantages of reporting outcomes outweigh the disadvantages, and these challenges can be overcome, to create a more reliable, trustworthy and transparent NHS. Perhaps one of the main challenges has been the difficulty in collecting large amounts of clinically significant data able to quantify the performance of surgeons.

    Information Technologies being developed by NASA to assist astronaut-physician in responding to medical emergencies during long space flights are being employed for the improvement of women's health in the form of "smart surgical probe". This technology, initially developed for neurosurgery applications, not only has enormous potential for the diagnosis and treatment of breast cancer, but broad applicability to a wide range of medical challenges. For the breast cancer application, the smart surgical probe is being designed to "see" a suspicious lump, determine by its features if it is cancerous, and ultimately predict how the disease may progress. A revolutionary early breast cancer detection tool based on this technology has been developed by a commercial company and is being tested in human clinical trials at the University of California at Davis, School of Medicine. The smart surgical probe technology makes use of adaptive intelligent software (hybrid neural networks/fuzzy logic algorithms) with the most advanced physiologic sensors to provide real-time in vivo tissue characterization for the detection, diagnosis and treatment of tumors, including determination of tumor microenvironment and evaluation of tumor margins. The software solutions and tools from these medical applications will lead to the development of better real-time minimally-invasive smart surgical probes for emergency medical care and treatment of astronauts on long space flights.

    The radical economisation of the German health-care system has caused an increasing cost awareness. Following this trend, medical education has been identified as a possible expense factor. The theoretical and practical training of young doctors needs time and costs money. However, a detailed cost analysis is still not available, since the complex daily work schedule of young professionals only allows the calculation of single cost factors. Investigations in the USA estimate the costs of surgical training at US$ 80 000 per year and per resident. At present in Germany, surgical training is indirectly financed by the DRG flat rates of the health insurance companies. Possible alternatives include the implementation of a "training fond" which is financed by a percentage fee of the DRG's as well as an on-top funding by the federal government. This "training fond" would support only those surgical units that offer a structured and certified training to surgical residents. However, a systematic cost analysis of such a structured curriculum is necessary for any further discussion.

  10. Updates on the Surgical Management of Pediatric Glaucoma.

    PubMed

    2016-01-01

    Childhood glaucoma is known to be one of the most challenging conditions to manage. Surgical management is more complicated than in adults because of differences in anatomy from adults along with variations in anatomy caused by congenital and developmental anomalies, wide-ranging pathogenetic mechanisms, a more aggressive healing response, and a less predictable postoperative course. Challenges in postoperative examination and management in less cooperative children and the longer life expectancies preempting the need for future surgeries and reinterventions are also contributing factors. Angle surgery is usually the first-line treatment in the surgical management of primary congenital glaucoma because it has a relatively good success rate with a low complication rate. After failed angle surgery or in cases of secondary pediatric glaucoma, options such as trabeculectomy, glaucoma drainage devices, or cyclodestructive procedures can be considered, depending on several factors such as the type of glaucoma, age of the patient, and the severity and prognosis of the disease. Various combinations of these techniques have also been studied, in particular combined trabeculotomy-trabeculectomy, which has been shown to be successful in patients with moderate-to-advanced disease. Newer nonpenetrating techniques, such as viscocanalostomy and deep sclerectomy, have been reported in some studies with variable results. Further studies are needed to evaluate these newer surgical techniques, including the use of modern minimally invasive glaucoma surgeries, in this special and diverse group of young patients.

    Urachal abnormalities represent a rare pathology and, in case of presence, they are more frequent in children and, among adults, in men. We report a case of urachal cyst in an adult woman in whom it was difficult to determine preoperatively the origin of the abdominal tumor. Positive diagnosis and treatment implied surgical exploration and resection. Even rare, this pathology should be considered in the differential diagnosis of an abdominal cyst. While the diagnosis may be established by clinical examination and imaging methods, surgical exploration is justified and, besides, offers the therapeutic opportunity.

    The planning for surgery in war was revisited in 1937 when Ian Fraser was elected a member of the Surgical Travellers. At their 1938 Surgical Travellers meeting in Vienna, Ian and Eleanor Fraser were evicted from their hotel room by the Nazis. The 1939 meeting in Belfast discussed the organization of surgery and the conduct of Emergency Medical Service Hospitals in the United Kingdom; the vast majority were to be under civilian government and military control. From 1943 lengthy and informative organizational meetings were held at least monthly under the chairmanship of Sir Alexander Hood, KBE, Head of the RAMC. Surgical Consultants, now Major Generals, Brigadiers or Full Colonels in the British and U.S. Armies stationed in the UK, prepared for the invasion of Europe. The allocation of medical, surgical, nursing and auxiliary responsibilities was delineated. Liaison with the RAF and US Army Air Force was close as it was with the proposed leaders, Ulstermen Brooke and Montgomery. Montgomery chose Arthur Porritt as Surgeon in Chief to Supreme Headquarters Allied Expeditionary Force (SHAEF), and Eisenhower, General Albert W. Kenner. Just after D-Day, Porritt met Ian Fraser, who had waded in on Arromanches Beach. The triage and evacuation plans for Allied casualties had been controversial, particularly as regards Landing Ship Tanks (LSTs). The dispute with the Hood-selected surgeons on one side, against medical and surgical deployment of LSTs, and Admiral Ernest King and Winston Churchill on the other, favouring LST use for surgery and evacuation. King and Churchill were correct but total Allied air superiority allowed wide use of many of the Allies' Dakotas; 10,000 DC-3s were eventually in service. Supported by forty Allied combat planes to each Luftwaffe, the dispute about Landing Ship Tank use in about a fortnight became moot.

    ABSTRACT Objective: to build and validate a scale to assess the risk of surgical positioning injuries in adult patients. Method: methodological research, conducted in two phases: construction and face and content validation of the scale and field research, involving 115 patients. Results: the Risk Assessment Scale for the Development of Injuries due to Surgical Positioning contains seven items, each of which presents five subitems. The scale score ranges between seven and 35 points in which, the higher the score, the higher the patient's risk. The Content Validity Index of the scale corresponded to 0.88. The application of Student's t-test for equality of means revealed the concurrent criterion validity between the scores on the Braden scale and the constructed scale. To assess the predictive criterion validity, the association was tested between the presence of pain deriving from surgical positioning and the development of pressure ulcer, using the score on the Risk Assessment Scale for the Development of Injuries due to Surgical Positioning (p<0.001). The interrater reliability was verified using the intraclass correlation coefficient, equal to 0.99 (p<0.001). Conclusion: the scale is a valid and reliable tool, but further research is needed to assess its use in clinical practice. PMID:27579925

    Background and Aims: Considering the paucity of regional data, this study was designed to investigate the prevalence of post-operative pain and determine if there exists any correlation between the intensity of post-operative pain and patient's level of satisfaction with their pain management after inpatient abdominal surgery at an academic tertiary care government centre. Methods: Pain intensity was measured in 120 patients with numeric rating scale at the fifth post-operative hour, second and third post-operative day. A questionnaire was used to measure the level of satisfaction with nurse's and doctor's response to their pain and overall pain management. Results: The prevalence of post-operative pain was 84.17%, 92.5% and 96.66% at the fifth post-operative hour, second and third post-operative day, respectively. Less number of patients experienced severe intensity pain on the third post-operative day (P = 0.00046), whereas the number of patients experiencing mild pain increased (P < 0.000) compared to the fifth post-operative hour. The number of patients with complete analgesia decreased on the third post-operative day (P = 0.001 compared to fifth post-operative day). The Spearman correlation coefficient between pain score on the third post-operative day and level of satisfaction with nurse's response, doctor's response to pain and the overall pain management was − 0.0218 (P = 0.8107), 0.1307 (P = 0.1553) and 0.0743 (P = 0.4195), respectively. Conclusion: There is a high prevalence of acute post-operative pain in patients undergoing inpatient abdominal surgery at our institute. There is a weak correlation between the intensity of pain and level of satisfaction with pain management. PMID:27761037

    Background: Echocardiography is one of the diagnostic tools that can be applied at the bedside, along with avoiding transporting critically ill patients. This prospective observational study was designed to assess the clinical applicability of the transthoracic echocardiography (TTE) device by noncardiologist intensivists. Materials and Methods: Intensivists performed a limited TTE examination on critically ill patients admitted to the surgical intensive care unit (ICU). After initial cardiac clinical assessment in 85 critically ill adult patients, a limited TTE was performed by an intensivist to assess left ventricular (LV) function and LV volume status as well as valvular function and qualitative factors. Data were analyzed and presented in proportions using descriptive statistics. The setting was in surgical ICU of an academic medical center. Results: Valvular abnormalities (44.8%) as well as qualitative indices (68.3%) were the most frequently detected abnormalities. The ejection fraction was the only alteration, which was affected by the risk factors (P = 0.05, mean = 55.57). Conclusion: Transthoracic approach can provide useful information on cardiac anatomy and function in most ICU patients along with detecting severe previously unknown conditions in some patients.

    Tracheostomy is a relatively common surgical procedure that is performed easily in an operating room or intensive care unit. Open tracheostomy is needed in patients requiring prolonged ventilation when percutaneous tracheostomy is inappropriate. Sometimes, it is difficult to achieve bleeding control in the peritracheal soft tissue, and in such cases, we usually use diathermy. However, the possibility of an electrocautery-ignited surgical field fire can be overlooked during the procedure. This case report serves as a reminder that the risk of a surgical field fire during tracheostomy is real, particularly in patients requiring high-oxygen therapy. PMID:25346908

The use of ultrasonography to locate the testis before and during the procedures and species-specific positioning during surgery greatly facilitated this distinctive procedure. Additionally, this surgical method provides an important additional tool for captive management of the common hippopotamus. Castration of individual males not only facilitates population control but can potentially also be employed to limit intermale aggression.

    There is growing evidence that childhood surgical conditions, especially injuries, are common in developing countries and that poor care results in significant numbers of deaths and cases of disability. Unfortunately, however, surgical care is not considered an essential component of most child health programmes. Strategies for improving paediatric surgical care should be evidence-based and cost-effective and should aim to benefit the largest possible number of children. The most likely way of achieving policy change is to demonstrate that childhood surgical conditions are a significant public health problem. For paediatric purposes, special attention should also be given to defining a cost-effective package of surgical services, improving surgical care at the community level, and strengthening surgical education. Surgical care should be an essential component of child health programmes in developing countries. PMID:12471405

    This review looks at the implementation of magnetic-based approaches in surgical instruments for abdominal surgeries. As abdominal surgical techniques advance toward minimizing surgical trauma, surgical instruments are enhanced to support such an objective through the exploration of magnetic-based systems. With this design approach, surgical devices are given the capabilities to be fully inserted intraabdominally to achieve access to all abdominal quadrants, without the conventional rigid link connection with the external unit. The variety of intraabdominal surgical devices are anchored, guided, and actuated by external units, with power and torque transmitted across the abdominal wall through magnetic linkage. This addresses many constraints encountered by conventional laparoscopic tools, such as loss of triangulation, fulcrum effect, and loss/lack of dexterity for surgical tasks. Design requirements of clinical considerations to aid the successful development of magnetic surgical instruments, are also discussed.

    OBJECTIVES--To evaluate trends in referrals for emergency operations after percutaneous transluminal coronary angioplasty (PTCA) complications; to analyse morbidity and mortality and assess the influence of PTCA backup on elective surgery. DESIGN--A retrospective analysis of patients requiring emergency surgical revascularisation within 24 hours of percutaneous transluminal coronary angioplasty. PATIENTS--Between January 1980 and December 1990, 75 patients requiring emergency surgery within 24 hours of percutaneous transluminal coronary angioplasty. SETTING--A tertiary referral centre and postgraduate teaching hospital. RESULTS--57 patients (76%) were men, the mean age was 55 (range 29-73) years, and 30 (40%) had had a previous myocardial infarction. Before PTCA, 68 (91%) had severe angina, 59 (79%) had multivessel disease, and six (8%) had a left ventricular ejection fraction of less than 40%. A mean of 2.1 grafts (range one to five) were performed; the internal mammary artery was used in only one patient. The operative mortality was 9% and inhospital mortality was 17%. There was a need for cardiac massage until bypass was established in 19 patients (25%): this was the most important outcome determinant (P = 0.0051) and was more common in those patients with multivessel disease (P = 0.0449) and in women (P = 0.0388). In 10 of the 19 cases a vacant operating theatre was unavailable, the operation being performed in the catheter laboratory or anaesthetic room. These 19 patients had an operative mortality of 32% and inhospital mortality of 47%, compared with 2% and 7% respectively for the 56 patients who awaited the next available operating theatre. Complications included myocardial infarction, 19 patients (25%); arrhythmias, 10 patients (3%); and gross neurological event, two patients (3%). The mean intensive care unit stay was 2.6 days (range 1 to 33 days) and the mean duration of hospital admission was 13 days (range 5-40 days). CONCLUSIONS--Patients undergoing

An open architecture portable surgical robotic system (Raven) was developed for both open and minimally invasive surgery. The system has been the subject of an intensive telesurgical experimental protocol aimed at exploring the boundaries of the system and surgeon performance during a series of field experiments in extreme environments (desert and underwater) teleportation between US, Europe, and Japan as well as lab experiments under synthetic fixed time delay. One standard task (block transfer emulating tissue manipulation) of the Fundamentals of Laparoscopic Surgery (FLS) training kit was used for the experimental protocol. Network characterization indicated a typical time delay in the range of 16-172 ms in field experiments. The results of the lab experiments showed that the completion time of the task as well as the length of the tool tip trajectory significantly increased (alpha< 0.02) as time delay increased in the range of 0-0.5 sec increased. For teleoperation with a time delay of 0.25s and 0.5s the task completion time was lengthened by a factor of 1.45 and 2.04 with respect to no time delay, whereas the length of the tools' trajectory was increased by a factor of 1.28 and 1.53 with respect to no time delay. There were no statistical differences between experienced surgeons and non-surgeons in the number of errors (block drooping) as well as the completion time and the tool tip path length at different time delays.

    Monopolar transurethral resection of the prostate (TURP) with endoscopic electrocautery remains the gold standard surgical technique for benign prostatic hypertrophy (BPH) by which all new procedures are compared. We reviewed the current literature, and international urological guidelines and consensus opinion on various surgical options for BPH and present a brief overview of alternative techniques including bipolar TURP, transurethral incision of the prostate, transurethral vaporization of the prostate, laser prostatectomy (with holmium, thulium and potassium titanyl phosphate greenlight lasers) and open prostatectomy (with mention of new techniques including laparoscopic and robotic prostatectomy). Emerging, experimental and less established techniques are also described including endoscopic heat generation (transurethral microwave thermotherapy, radiofrequency transurethral needle ablation of the prostate, high intensity focused ultrasound, hot water induced thermotherapy, pulsed electromagnetic radiofrequency), injection therapy (transurethral ethanol ablation and botulinum toxin) and mechanical devices (intraprostatic stents and urethral lift devices). Despite a plethora of surgical options, none have realistically improved outcomes in the long-term compared with TURP. Improvements have been made on improving surgical morbidity and time in hospital. Questions remain in this area, including what specific elements of bladder outflow obstruction (BOO) result in damage to the urinary tract, how does BPH contribute to BOO and how much prostate volume reduction is necessary to relieve BOO or lower urinary tract symptoms. Given these unanswered questions and the multitude of procedures available, it is clear that appropriate counselling is necessary in all men who undergo BPH surgery. PMID:24744521

    Nutritional status of patients significantly affects the outcome of surgical treatment, whether it's about being obese or malnutrition with loss of muscle mass. Inadequate nutritional support in the perioperative period compromises surgical procedures even in patients who are adequately nourished. In this paper, particular attention was paid to malnourished patients, and their incidence in population hospitalized in surgical wards can be high up to 30%. Special emphasis was paid to the appropriateness of preoperative fasting and to the acceptance of new knowledge in this area of treatment. The aim of this working group was to make guidelines for perioperative nutritional support with different modalities of enteral nutrition. The development of these guidelines was attended by representatives of Croatian Medical Association: Croatian Society for Digestive Surgery, Croatian Society for Clinical Nutrition, Croatian Society of Surgery, Croatian Society for Endoscopic Surgery, Croatian Trauma Society and the Croatian Society of Anesthesiology and Intensive Care. The guidelines are designed as a set of questions that arise daily in clinical practice when preparing patients for surgery and after the surgical treatment, which relate to the assessment of nutritional status, perioperative nutritional support, duration of preoperative fasting period and the selection of food intake route. Assessment of nutritional status and the use of different modes of enteral nutrition should enter into standard protocols of diagnosis and treatment in the Croatian hospitals.

  6. Luminous efficiency functions at higher intensities

    NASA Astrophysics Data System (ADS)

    Harrington, Lawrence Kent

    Two psychophysical measurement techniques, flicker photometry and successive heterochromatic brightness matching, were used to measure changes in luminance efficiency functions with increasing levels of light adaptation. Both measurement techniques were performed using the same optical system and the same seven healthy adults as subjects. Measurements were taken at four reference stimulus intensities, 1, 10, 100 and 1000 foot-lamberts. Luminous efficiency was found to depend on both the technique and the reference stimulus intensity with which the measurements were taken. For heterochromatic brightness matching, luminous efficiency increased for longer wavelengths as reference intensity increased. Peak luminous efficiency shifted from approximately 540nm to greater than 600nm with increasing intensity for all seven subjects. Peak luminous efficiency was constant for flicker photometry across all intensities but the function narrowed slightly at 100 foot-lamberts.

    Hyperglycemia has been found to be associated with increased morbidity and mortality in surgical patients, yet, the optimal glucose management strategy during the perioperative setting remains undetermined. While much has been published about hyperglycemia and cardiac surgery, most studies have used widely varying definitions of hyperglycemia, methods of insulin administration, and the timing of therapy. This has only allowed investigators to make general conclusions in this challenging clinical scenario. This review will introduce the basic pathophysiology of hyperglycemia in the cardiac surgery setting, describe the main clinical consequences of operative hyperglycemia, and take the reader through the published material of intensive and conservative glucose management. Overall, it seems that intensive control has modest benefits with adverse effects often outweighing these advantages. However, some studies have indicated differing results for certain patient subgroups, such as non-diabetics with acute operative hyperglycemia. Future studies should focus on distinguishing which patient populations, if any, would optimally benefit from intensive insulin therapy. PMID:26879308

    Pediatric epilepsy is a debilitating condition that impacts millions of patients throughout the world. Approximately 20–30% of children with recurrent seizures have drug-resistant epilepsy (DRE). For these patients, surgery offers the possibility of not just seizure freedom but significantly improved neurocognitive and behavioral outcomes. The spectrum of surgical options is vast, ranging from outpatient procedures such as vagus nerve stimulation to radical interventions including hemispherectomy. The thread connecting all of these interventions is a common goal—seizure freedom, an outcome that can be achieved safely and durably in a large proportion of patients. In this review, we discuss many of the most commonly performed surgical interventions and describe the indications, complications, and outcomes specific to each. PMID:27186522

    Surgical skin-marking inks and dyes are in everyday use for designing and planning incisions in plastic and reconstructive surgery. We have traced the historical development of surgical skin-marking techniques from ancient times to the present. The biochemical characteristics of the commonly used marking agents are discussed. A three-part experiment utilizing a pig model was carried out to test the tissue inflammatory response to the various dyes and inks when used intradermally as tattoos, the persistence of such tattoos, and the ease of skin erasure for each of eight stains. Methylene blue and gentian violet are recommended as the best all-purpose marking agents. The use of proprietary inks is discouraged.

    There is good evidence that neonatal hepatitis, biliary hypoplasia, biliary atresia and choledochal cyst are different stages of one disease process for which the term infantile obstructive cholangiopathy has been suggested. Thanks to the work of Kasai and the operation of hepatic portoenterostomy the surgical outlook has greatly improved, although in North America it still leaves much to be desired. One cannot procrastinate too long in the hope that the patient's condition will improve spontaneously, because the surgical results are much better when the operation is performed before the patient is 10 weeks old. This article outlines the steps that should be followed in investigating neonatal jaundice, the nonsurgical measures that can be taken in an attempt to reverse or alleviate the underlying condition, and the specific role of the pediatric surgeon in the management of choledochal cyst and biliary atresia.

    Vaccination is recommended throughout life to prevent vaccine-preventable diseases and their sequel. The primary focus of vaccination programs has historically been directed to childhood immunizations. For adults, chronic diseases have been the primary focus of preventive and medical health care, though there has been increased emphasis on preventing infectious diseases. Adult vaccination coverage, however, remains low for most of the routinely recommended vaccines. Though adults are less susceptible to fall prey to traditional infectious agents, the probability of exposure to infectious agents has increased manifold owing to globalization and increasing travel opportunities both within and across the countries. Thus, there is an urgent need to address the problem of adult immunization. The adult immunization enterprise is more complex, encompassing a wide variety of vaccines and a very diverse target population. There is no coordinated public health infrastructure to support an adult immunization program as there is for children. Moreover, there is little coordination among adult healthcare providers in terms of vaccine provision. Substantial improvement in adult vaccination is needed to reduce the health consequences of vaccine-preventable diseases among adults. Routine assessment of adult patient vaccination needs, recommendation, and offer of needed vaccines for adults should be incorporated into routine clinical care of adults. PMID:24128707

    Background Electrocautery, laser tissue ablation, and ultrasonic scalpel tissue dissection all generate a 'surgical smoke' containing ultrafine (<100 nm) and accumulation mode particles (< 1 μm). Epidemiological and toxicological studies have shown that exposure to particulate air pollution is associated with adverse cardiovascular and respiratory health effects. Methods To measure the amount of generated particulates in 'surgical smoke' during different surgical procedures and to quantify the particle number concentration for operation room personnel a condensation particle counter (CPC, model 3007, TSI Inc.) was applied. Results Electro-cauterization and argon plasma tissue coagulation induced the production of very high number concentration (> 100000 cm-3) of particles in the diameter range of 10 nm to 1 μm. The peak concentration was confined to the immediate local surrounding of the production side. In the presence of a very efficient air conditioning system the increment and decrement of ultrafine particle occurrence was a matter of seconds, with accumulation of lower particle number concentrations in the operation room for only a few minutes. Conclusion Our investigation showed a short term very high exposure to ultrafine particles for surgeons and close assisting operating personnel – alternating with longer periods of low exposure.

    Decisions in surgical oncology are increasingly being made by multi-disciplinary teams (MDTs). Although MDTs have been widely accepted as the preferred model for cancer service delivery, the process of decision making has not been well described and there is little evidence pointing to the ideal structure of an MDT. Performance in surgery has been shown to depend on non-technical skills, such as decision making, as well as patient factors and the technical skills of the healthcare team. Application of this systems approach to MDT working allows the identification of factors that affect the quality of decision making for cancer patients. In this article we review the literature on decision making in surgical oncology and by drawing from the systems approach to surgical performance we provide a framework for understanding the process of decision making in MDTs. Technical factors that affect decision making include the information about patients, robust ICT and video-conferencing equipment, a minimum dataset with expert review of radiological and pathological information, implementation and recording of the MDTs decision. Non-technical factors with an impact on decision making include attendance of team members at meetings, leadership, teamwork, open discussion, consensus on decisions and communication with patients and primary care. Optimising these factors will strengthen the decision making process and raise the quality of care for cancer patients.

    A virtual intraoperative surgical photoacoustic microscopy at 1064 nm wavelength (VISPAM) system was designed and fabricated by integrating a commercial type surgical microscope and laser scanning photoacoustic microscopy (PAM) with a 1064 nm pulsed laser. Based on simple augmented reality device, VISPAM could simultaneously provide 2D depth-resolved photoacoustic and magnified microscope images of surgery regions on the same vision of surgeon via an eyepiece of the microscope. The invisible 1064 nm laser removed the interruption of surgical sight due to visible laser scanning of previous report, and decreased the danger of tissue damage caused by over irradiated laser. In addition, to approach the real practical surgery application, a needle-type transducer was utilized without a water bath for PA signal coupling. In order to verify our system's performance, we conducted needle guiding as ex vivo phantom study and needle guiding and injection of carbon particles mixtures into a melanoma tumor region as in vivo study. We expect that VISPAM can be essential tool of brain and ophthalmic microsurgery.

  3. Ethical issues in surgical innovation.

    Miller, Megan E; Siegler, Mark; Angelos, Peter

    2014-07-01

    Innovation is responsible for most advances in the field of surgery. Innovative approaches to solving clinical problems have significantly decreased morbidity and mortality for many surgical procedures, and have led to improved patient outcomes. While innovation is motivated by the surgeon's expectation that the new approach will be beneficial to patients, not all innovations are successful or result in improved patient care. The ethical dilemma of surgical innovation lies in the uncertainty of whether a particular innovation will prove to be a "good thing." This uncertainty creates challenges for surgeons, patients, and the healthcare system. By its very nature, innovation introduces a potential risk to patient safety, a risk that may not be fully known, and it simultaneously fosters an optimism bias. These factors increase the complexity of informed consent and shared decision making for the surgeon and the patient. Innovative procedures and their associated technology raise issues of cost and resource distribution in the contemporary, financially conscious, healthcare environment. Surgeons and institutions must identify and address conflicts of interest created by the development and application of an innovation, always preserving the best interest of the patient above the academic or financial rewards of success. Potential strategies to address the challenges inherent in surgical innovation include collecting and reporting objective outcomes data, enhancing the informed consent process, and adhering to the principles of disclosure and professionalism. As surgeons, we must encourage creativity and innovation while maintaining our ethical awareness and responsibility to patients.

    The reduction in time for training at the workplace has created a challenge for the traditional apprenticeship model of training. Simulation offers the opportunity for repeated practice in a safe and controlled environment, focusing on trainees and tailored to their needs. Recent technological advances have led to the development of various simulators, which have already been introduced in surgical training. The complexity and fidelity of the available simulators vary, therefore depending on our recourses we should select the appropriate simulator for the task or skill we want to teach. Educational theory informs us about the importance of context in professional learning. Simulation should therefore recreate the clinical environment and its complexity. Contemporary approaches to simulation have introduced novel ideas for teaching teamwork, communication skills and professionalism. In order for simulation-based training to be successful, simulators have to be validated appropriately and integrated in a training curriculum. Within a surgical curriculum, trainees should have protected time for simulation-based training, under appropriate supervision. Simulation-based surgical education should allow the appropriate practice of technical skills without ignoring the clinical context and must strike an adequate balance between the simulation environment and simulators.

    To evaluate fungal microbiota in air-conditioning units installed in intensive care units in two university hospitals in Cuiaba city, Mato Grosso, central western region of Brazil, 525 solid environmental samples were collected, 285 from Hospital A and 240 from Hospital B. Collections were performed using sterile swabs on air-conditioning unit components: cooling coils, ventilators, and filters. Mycelial fungi identification was achieved by observation of the macroscopic and micromorphological characteristics in different culture mediums (maize meal, oatmeal and potato dextrose agars and malt extract) using the Ridell technique. Eleven genera and 27 distinct species belonging to the hyphomycetes and ascomycetes classes were isolated and identified. The most frequently detected genera in both hospitals were Aspergillus spp, Penicillium spp, and Cladosporium spp. Values for colony-forming units per gram were 64 and 75%, well above the limits recommended by Health Ministry resolution 176/00 at the locations selected for analysis in Hospitals A and B, respectively. In conclusion, evaluation of fungal microbiota in the air-conditioning units indirectly determined that the air quality was compromised in both university hospitals analyzed, which constitutes a risk factor for the acquisition of infection in the intensive care units.

The median age was 5.45 years (range 3-13), and median weight was 19.84 Kg. (range 13-37). The defect was closed directly in 13 cases, and with an autologous pericardial patch in the other 13. The number of surgical steps and time taken were the same as in median sternotomy. Functional recovery, intensive care unit stay, and hospital discharge were also standard. The cosmetic result, assessed both by patients and relatives, was excellent.

    Recent advances in surgical corrections and supportive care for congenital heart disease have resulted in increasing numbers of adult survivors who may develop hematological malignancies. Treatments including chemotherapy for such patients may cause serious hemodynamic or cardiac complications, especially in those receiving stem cell transplantation. We present a 29-year-old woman with acute lymphoblastic leukemia and congenital heart disease. She had been diagnosed with pulmonary atresia with an intact ventricular septum at birth, and the anomaly was surgically corrected according to the Fontan technique at age 9 years. Her induction chemotherapy required modifications due to poor cardiac status with Fontan circulation. However, after surgical procedures including total cavopulmonary connection and aortic valve replacement at first complete remission, her cardiac status was significantly improved. Subsequently, she underwent cord blood stem cell transplantation at the third complete remission. She required intensive supportive care for circulatory failure as a pre-engraftment immune reaction and stage III acute graft versus host disease of the gut, but recovered from these complications. She was discharged on day 239, and remained in complete remission at 1-year post-transplantation. PMID:27599417

    In a series of 61 adult cadavers, the posterior gastric artery was found in 38 (62.3%), originating from the superior aspect of the mid-third of the splenic artery. The posterior gastric artery, running behind the parietal peritoneum of the omental bursa, produced a peritoneal fold before reaching the posterior wall of the superior portion of the gastric body, near the cardiac region, and the fundus. Its high incidence, hidden origin, deep course, and distribution make this artery very important for surgical procedures relating to the stomach, pancreas, spleen, and celiac region. It may be crucial, especially if partial gastric resection of splenectomy have obliterated other gastric vessels. PMID:629615

    The authors describe an adult patient with a giant, cystic teratoma (33 x 22 x 18 cm) involving the posterior mediastinum and retroperitoneum. A conservative surgical approach consisting of a partial endocystectomy plus injections of tetracycline into the residual cavity, was performed. Two months after surgery, a CT scan showed a 6 x 5 x 3 cm residual cyst. The authors believe that the excision of the inner surface of the cystic lesion and the intracystic administration of tetracycline, may successfully prevent the accumulation of fluid which is the main cause of the progressive enlargement of such benign cystic teratomas.

To meet growing need for appropriate training in laparoscopic and, even more importantly, classic surgical skills, a curriculum involving contemporary tuition methods is needed. Advanced, structuralised training, which includes advanced technologies like virtual reality training, video coaching and motivative aspects of competition, seems to be important for an adequate education programme. Material and methods In academic years 2009/2010 and 2010/2011 the Department of General, Endocrine and Transplant Surgery of the Medical University of Gdansk together with the Pomeranian Foundation for Progress in Surgery organized 4480 h of training in that area of classic (2744) and laparoscopic (1736) skills. Both groups were involved in the programme of training in which the two most important aspects were reliable evaluation of the results and effective motivation to work. Skill evaluation at different stages of the programme were based on completion time and quality measurements. Apart from that, at the end of the course, the participants completed a questionnaire on their subjective perspective on this innovative curriculum, the quality and stability of the skills they obtained. Results In both arms of the programme (laparoscopic and classic) a statistically significant improvement was obtained as early as after the second and third sessions in half of the exercises. The acquired skills were stable over time, as proved by the plateau of completion time achieved in 11 out of 12 exercises. The results of the post-training questionnaire revealed that the participants were very satisfied with the structuralised form of training and appreciated the motivational role of competition. Conclusions Contemporary surgical training should be organized as a systematic, well-evaluated and goal-oriented programme similar to the one proposed by our team. The use of contemporary

    Background. A new influenza A/H1N1 (pH1N1) virus emerged in April 2009, proceeded to spread worldwide, and was designated as an influenza pandemic. A/H1N1 viruses had circulated in 1918–1957 and 1977–2009 and were in the annual vaccine during 1977–2009. Methods. Serum antibody to the pH1N1 and seasonal A/H1N1 viruses was measured in 579 healthy adults at enrollment (fall 2009) and after surveillance for illness (spring 2010). Subjects reporting with moderate to severe acute respiratory illness had illness and virus quantitation for 1 week; evaluations for missed illnesses were conducted over holiday periods and at the spring 2010 visit. Results. After excluding 66 subjects who received pH1N1 vaccine, 513 remained. Seventy-seven had reported with moderate to severe illnesses; 31 were infected with pH1N1 virus, and 30 with a rhinovirus. Determining etiology from clinical findings was not possible, but fever and prominent myalgias favored influenza and prominent rhinorrhea favored rhinovirus. Tests of fall and spring antibody indicated pH1N1 infection of 23% had occurred, with the rate decreasing with increasing anti-pH1N1 antibody; a similar pattern was seen for influenza-associated illness. A reducing frequency of pH1N1 infections was also seen with increasing antibody to the recent seasonal A/H1N1 virus (A/Brisbane/59/07). Preexisting antibody to pH1N1 virus, responses to a single vaccine dose, a low infection-to-illness ratio, and a short duration of illness and virus shedding among those with influenza indicated presence of considerable preexisting immunity to pH1N1 in the population. Conclusions. The 2009 A/H1N1 epidemic among healthy adults was relatively mild, most likely because of immunity from prior infections with A/H1N1 viruses. PMID:22075792

    This is a report on the surgical intervention in 79 patients with acute pancreatitis, who were operated in the Department of Surgery of the University Clinic RWTH Aachen in the period from 1986 to 1993. The main objective was the stratification of pancreatitis according to the Ranson-Score, the analysis of the surgical treatment and the timing of operation depending on the clinical condition. The average Ranson-score was 3.3 (median 3). 56 patients had necroses, which were removed because of the deteriorating clinical condition. In these cases the average Ranson-score was 4.2 (median 4). Seven patients (8.9% of the total number and 12.5% of the patients with necroses of the pancreas) died. This small number is the result of a severity-adapted management in a modern intensive care-unit and the good cooperation with the Department of Internal Medicine.

    Traditional department-based surgical interest groups in Russian medical schools are useful tools for student-based selection of specialty training. They also form a nucleus for initiating research activities among undergraduate students. In Russia, the Departments of Topographical Anatomy and Operative Surgery play an important role in initiating student-led research and providing learners with advanced, practical surgical skills. In tandem with department-led activities, student surgical interest groups prepare learners through surgical competitions, known as "Surgical Olympiads," which have been conducted in many Russian centers on a regular basis since 1988. Surgical Olympiads stimulate student interest in the development of surgical skills before graduation and encourage students to choose surgery as their postgraduate specialty. Many of the participants in these surgical Olympiads have become highly qualified specialists in general surgery, orthopedic surgery, neurosurgery, urology, gynecology, and emergency medicine. The present article emphasizes the role of student interest groups and surgical Olympiads in clinical anatomical and surgical undergraduate training in Russia.

    The University of Rochester, Department of Surgery, in response to an experimental community-wide limit on hospital budgets, studied high-cost general surgical patients as a potential source of leverage for containment of hospital costs. It was found that a small number of patients impact significantly on hospital costs. In 1980, 3935 patients at Strong Memorial Hospital (SMH) had at least one contact with a general surgical patient care or intensive care unit; 261 patients (6.6%) had total 1980 charges of more than $20,000 each. They contributed 32% of the total of both general surgical charges and patient days. A subset of 2021 patients was selected to represent more precisely the general surgical patient. The 85 high-cost patients (4.2%) of this subset were chosen for intensive study. These patients generated a significant and disproportionate per cent of total (2021) general surgical charges (26.8%) and hospital days (27.6%). Average total charges were more than 8 times those of the complementary general surgical subset (1936). Nineteen of the 85 patients (22.3%) died in the hospital and 42 patients (49.4%) were dead within 2 1/2 years. Forty patients (of the 85) were then further identified as "complex", based on multiple, usually unrelated, illnesses and multiple annual admissions. Tending to be elderly with poor prognoses, 60% of them had died by April 1983. The major criterion of complexity was the lack of a well-focused medical problem; the cure for one problem simply relinquished primacy to another. A parallel study of hospital ancillary procedures disclosed a similar high-cost pattern. Of approximately 4000 ancillary procedures, 100 (2.5%) had annual charges of $100,000 or over, accounting for two-thirds of total 1980 ancillary charges. Roughly 20% of a single patient's ordered procedures accounted for 80% of the patient's ancillary charges, thus allowing concentrated study of a relatively small number of charges.

Forty two children and teenagers at the Hospital de Pediatria (1983-1985/1989-1998) and Hospital General La Raza (1985-1989) were included also, 10 adults including those operated on at the Hospital de Especialidades, CMN Siglo XXI (IMSS) from 1998 to 2001 were included. We used Dunn modified method en 37 cases (67%) and 17 patients were with Risdon operated on technique (33%). Etiology of ankylosis were direct trauma to jaw, which affected temporomandibular joint mainly in children, while in adults causes were more varied and included as osteomyelitis, middle ear infection, sequels of hemifacial microsomy, and trauma results were considered as good upon obtaining mouth opening of 35 mm without neo-ankylosis during 1-year postoperative control.

    The correction of skeletal Class III malocclusion with severe mandibular prognathism in an adult individual requires surgical and Othodontic combination therapy. The inter disciplinary approach is the treatment of choice in most of the skeletal malocclusions. A case report of an adult individual with Class III malocclusion, having mandibular excess in sagittal and vertical plane and treated with orthodontics,, bilateral sagittal split osteotomy and Le – Forte I osteotomy for the correction of skeletal, dental and soft tissue discrepancies is herewith presented. The surgical–orthodontic combination therapy has resulted in near–normal skeletal, dental and soft tissue relationship, with marked improvement in the facial esthetics in turn, has helped the patient to improve the self-confidence level.

    Symptomatic os trigonum is a rare condition, well described in adults, that causes chronic ankle pain. To date there are no reported cases of successfully managed symptomatic os trigonum in the children population. We retrospectively reviewed four paediatric patients (11-17 years of age) successfully operated for a symptomatic os trigonum using an open excision through a posteromedial approach. One case was bilateral. Postoperative pain relief was obtained in all cases. All of the patients were able to return to unrestricted physical activities after three months. The average follow-up was 12 months. Symptomatic os trigonum may be held responsible for chronic ankle pain in children and adolescents as well as in adults. The surgical treatment is effective in children.

    Digitization of glass slides of surgical pathology samples facilitates a number of value-added capabilities beyond what a pathologist could previously do with a microscope. Image analysis is one of the most fundamental opportunities to leverage the advantages that digital pathology provides. The ability to quantify aspects of a digital image is an extraordinary opportunity to collect data with exquisite accuracy and reliability. In this review, we describe the history of image analysis in pathology and the present state of technology processes as well as examples of research and clinical use. PMID:27241112

    Lesson plans in surgery enable trainers and trainees to agree on goals that balance training needs with service commitments. Lesson plans are individualised to the trainee and encourage ownership of learning. They are based on SMART criteria and therefore have a sound educational footing. Most of the work in creating a lesson plan falls to the trainee. The total time for creation of each plan is approximately 20 min. Our use of lesson plans for surgical training has been met with favourable response from both trainer and trainees.

    The objective was to determine the role of dose intensive induction chemotherapy in patients with soft tissue sarcomas (STS) that were considered unresectable. Treatment consisted of 2-3 cycles of doxorubicin (Dox) and ifosfamide (Ifo) followed by high dose chemotherapy with ifosfamide, carboplatin, etoposide (HD-ICE) plus peripheral blood stem cell transplantation (PBSCT). 30 out of 631 consecutive patients, median age 46 years (21-62), with high grade STS were included. 29 patients completed at least 2 cycles of Dox/Ifo. HD-ICE was withheld because of progressive disease (PD) in 5 patients, neurotoxicity in 6 cases, insufficient peripheral blood stem cell (PBSC) mobilization, complete remission (CR) and refusal in 1 patient each. HD-ICE was associated with non-haematological grade III toxicity including emesis, mucositis, fever, neurotoxicity, and transaminase level elevation. Two additional patients attained a partial response after HD-ICE. Overall, 24 of 30 (80%) patients underwent surgery, with complete tumor resections in 19 patients (63% of all patients, 79% of the operated subgroup); however, 2 of these required amputation. After a median follow up period of 50 months in surviving patients (range, 26-120), 5-year PFS and OS rates were 39% and 48%, respectively. Induction chemotherapy plus consolidation HD-ICE is generally feasible, but is associated with significant neurotoxicity. The advantage of HD-ICE over conventional dose chemotherapy plus external beam radiation therapy (EBRT) in non-resectable disease remains unproven.

    Adult heartworms were surgically removed from 4 infected dogs by use of intracardiac techniques during cardiopulmonary bypass. The number of worms removed ranged from 12 to 14 per dog. Observation for 9 months after surgery gave no clinical evidence of active adult heartworm infection, in spite of the consistent finding of circulating microfilariae during the follow-up period. There were no significant early or late postoperative complications. Results of postoperative hematologic and biochemical studies were unremarkable. At necropsy (following euthanasia, 9 months after surgery) the heart and pulmonary arteries of all dogs were free of adult heartworms; pathologic changes attributable to residual infection were not found.

    Surgical Oncology has evolved as a distinct subspecialty of General Surgery with a well-defined curriculum focused on surgical care of the cancer patient, specific areas of clinical and basic science research focus and specialty journals dedicated to the discipline. The Society of Surgical Oncology (SSO), originally formed as the James Ewing Society, has provided leadership in developing training programs in Surgical Oncology and for three decades has been involved in the approval and oversight of Surgical Oncology training programs. Over this time, Surgical Oncology Fellowship training has expanded and in 2013 there were 103 applicants for 56 fellowship positions in 21 programs. The basic tenants of Surgical Oncology training has remained devoted to the core principles of multidisciplinary care, surgical management of cancer patients and a focus on education in research, clinical trials, community outreach, patient advocacy and leadership in oncology. With the maturation of Surgical Oncology as a separate specialty, Surgical Oncology training programs are now accredited by the Accreditation Council on Graduate Medical Education (ACGME) and graduates of the programs will soon be offered subspecialty certification in Complex General Surgical Oncology (CGSO) by the American Board of Surgery, which has created a component Surgical Oncology Board (SOB). Similar expansion has occurred in other specialty areas including an expansion of Breast Fellowships, which are still being approved by the SSO. In the 2013 SSO Breast Oncology Match, there were 67 applicants for 54 positions in 39 Breast Fellowship programs. Continued advances in cancer biology and technology will challenge us to evolve training programs in Surgical Oncology to produce surgeons capable of advancing the multidisciplinary care of cancer patients.

    2009-01-01

    Our objective was to evaluate high-intensity focused ultrasound (HIFU) for minimizing blood loss during surgery by hemodynamically isolating large portions of solid organs before their resection. A high-power HIFU device (in-situ intensity of 9000 W/cm2, frequency of 3.3 MHz) was used to produce a wall of cautery for sealing of blood vessels along the resection line in surgically-exposed solid organs (liver lobes, spleen and kidneys) of eight adult pigs. Following HIFU application, the distal portion of the organ was excised using a scalpel. If any blood vessels were still bleeding, additional HIFU application was used to stop the bleeding. The resection was achieved in 6.0 ± 1.5 min (liver), 3.6 ± 1.1 min (spleen) and 2.8 ± 0.6 min (kidneys) of HIFU treatment time, with no occurrence of bleeding for up to 4 hours (until sacrifice). The coagulated region at the resection line had average width of 3 cm and extended through the whole thickness of the organ (up to 4 cm). Blood vessels of up to 1 cm in size were occluded. This method holds promise for future clinical applications in resection of solid tumors and hemorrhage control from high-grade organ injuries. PMID:17498864

    Even when the number of patients with invasive amebiasis has decreased, the internist and surgeon must be alert in case that the patient requires an operation. Amebic liver abscess is treated medically; percutaneous evacuation is rarely used and surgical drainage is made when there is not response to medical treatment or there is high risk of abscess rupture. Operation is mandatory when the abscess has ruptured to the abdominal cavity or through the pericardial sac. In fulminant colitis it is necessary to resect the diseased portion of the colon without primary anastomoses. Amebic apendicitis is difficult to diagnosis before an operation. It may be suspected in cases of apendicitis if the cecal wall is inflammed. Colon ameboma requires medical treatment except if it is associated with necrosis or perforation. In a four year period (1985-1988) 294 patients with diagnosis of invasive amebiasis were admitted to three hospitals of the Instituto Mexicano del Seguro Social in Mexico City. 218 had hepatic abscess, 45 required surgical drainage with four deaths (9%) and four not operated patients died. In this series only four patients had their abscess drained percutaneously. 31 patients with amebic colitis were treated; three required colonic resection with one death. Ameboma was seen in five patients and there were 11 cases of amebic apendicitis. No deaths occurred in these last two groups.

  15. Surgical Reconstruction of Radiation Injuries

    Fujioka, Masaki

    2014-01-01

    Significance: Patients with cancer receive benefits from radiation therapy; however, it may have adverse effects on normal tissue such as causing radiation-induced ulcer and osteoradionecrosis. The most reliable method to treat a radiation ulcer is wide excision of the affected tissue, followed by coverage with well-vascularized tissue. As usual, radiation-induced skin ulcers are due to therapeutic irradiation for residual cancer or lymph nodes; the locations of radiation ulcers are relatively limited, including the head, neck, chest wall, lumbar, groin, and sacral areas. Thus, suitable reconstructive methods vary according to functional and aesthetic conditions. I reviewed the practices and surgical results for radiation ulcers over the past 30 years, and present the recommended surgical methods for these hard-to-heal ulcers. Recent Advances: At a minimum, flaps are required to treat radiation ulcers. Surgeons can recommend earlier debridement, followed by immediate coverage with axial-pattern musculocutaneous and fasciocutaneous flaps. Free flaps are also a useful soft tissue coverage option. The choice of flap varies with the location and size of the wounds. Critical Issues: The most crucial procedure is the complete resection of the radiation-affected area, followed by coverage with well-vascularized tissue. Future Directions: Recent developments in perforator flap techniques, which are defined as flaps with a blood supply from isolated perforating vessels of a stem artery, have allowed the surgeons to successfully resurface these difficult wounds with reduced morbidity.

    The impact of intensive lipid management, omega-3 fatty acid, and vitamin D3 supplementation on atherosclerotic plaque was assessed through serial computed tomography coronary calcium scoring (CCS). Low-density lipoprotein cholesterol reduction with statin therapy has not been shown to reduce or slow progression of serial CCS in several recent studies, casting doubt on the usefulness of this approach for tracking atherosclerotic progression. In an open-label study, 45 male and female subjects with CCS of > or = 50 without symptoms of heart disease were treated with statin therapy, niacin, and omega-3 fatty acid supplementation to achieve low-density lipoprotein cholesterol and triglycerides < or = 60 mg/dL; high-density lipoprotein > or = 60 mg/dL; and vitamin D3 supplementation to achieve serum levels of > or = 50 ng/mL 25(OH) vitamin D, in addition to diet advice. Lipid profiles of subjects were significantly changed as follows: total cholesterol -24%, low-density lipoprotein -41%; triglycerides -42%, high-density lipoprotein +19%, and mean serum 25(OH) vitamin D levels +83%. After a mean of 18 months, 20 subjects experienced decrease in CCS with mean change of -14.5% (range 0% to -64%); 22 subjects experienced no change or slow annual rate of CCS increase of +12% (range 1%-29%). Only 3 subjects experienced annual CCS progression exceeding 29% (44%-71%). Despite wide variation in response, substantial reduction of CCS was achieved in 44% of subjects and slowed plaque growth in 49% of the subjects applying a broad treatment program. PMID:19092644

    The survivors of the initial years of neonatal intensive care of preterm infants reached adulthood during the last decade. Reports of their adult outcomes examined have included neurodevelopmental, behavioral and health outcomes as well as social functioning and reproduction. Despite statistically significant differences between preterm young adults and controls in most outcomes studied, the majority of preterm survivors do well and live fairly normal lives. The two major predictors of adult outcomes are lower gestational age that reflect perinatal injury and family sociodemographic status which reflects both genetic and environmental effects.
