Coenzyme Q10 concentration in plasma and blood cells of juvenile patients hospitalized for anorexia nervosa

The antioxidant status of coenzyme Q10 (CoQ10) was investigated in plasma, erythrocytes, and platelets of juvenile patients with anorexia nervosa. Blood for analysis of the CoQ10 status was taken from 16 juvenile patients suffering from anorexia nervosa (restricting form) at the time point of admission to the hospital and at discharge after about 12 weeks. Plasma and blood cells isolated by a density gradient were stored at -84 °C until analysis. CoQ10 concentration and redox status were measured by high pressure liquid chromatography with electrochemical detection and internal standardization. The improvement of physical health during the hospital refeeding process was followed up by the body mass index (BMI). The antioxidant status of plasma CoQ10 in juvenile patients suffering from anorexia nervosa indicated no abnormalities in comparison to healthy controls. However, the decreased concentration of CoQ10 observed in platelets at the time point of hospital admission may represent mitochondrial CoQ10 depletion. This initial deficit improved during the hospital refeeding process. The platelet CoQ10 concentration showed a positive correlation to the BMI of the patients.     

Clinical significance of a high mean corpuscular volume in nonanemic patients.

A prospective study of the clinical significance of macrocytosis (mean corpuscular volume 100 fL or more) was carried out for 9 months in a teaching hospital in 1975. Of the 140 patients with macrocytosis at the time of admission (0l7% of all hospital admissions) 46 (33%) had low activity of serum or erythrocyte folate, or both, and 16 (11%) had low serum vitamin B12 concentrations. Among the 78 patients with normal B12 and folate values the most commonly associated significant clinical conditions were alcoholism or hepatic disease (36 patients), malignant disease or the effects of chemotherapy (25 patients) and chronic obstructive lung disease (10 patients).     

One Year's Experience in a Ministry of Health Dialysis Centre

A 10-bed dialysis unit, opened at the London Hospital in 1968, admitted 37 patients during its first year of operation. The aims of the unit were to prepare patients for renal transplantation and to provide instruction for dialysis treatment at home. A total of 2,012 days were spent in hospital, the average intervals between admission, the first dialysis, and discharge being 23·8 and 20 days, respectively. The overall number of readmissions was 1·5 per patient. These figures, together with the increasing number of patients accepted for such treatment, indicate the considerable number of supporting hospital beds, as well as medical and technical staff, required to maintain a dialysis unit.     

Streptokinase in Recent Myocardial Infarction: A Controlled Multicentre Trial

In this controlled multicentre trial treatment with either streptokinase or heparin was allocated at random to patients suffering from myocardial infarction of less than 24 hours'' duration. Treatment with either drug was standardized and lasted for 24 hours. A total of 764 patients entered the trial; 34 patient charts were rejected (including all 28 charts from one centre) because of data failure. On retrospective analysis of the 730 remaining patients the two groups were found to have been comparable at the start.The total hospital mortality was 18·5% of 373 patients allotted to streptokinase treatment and 26·3% of 357 given herapin. The mortality after infusion (24 hours) was 10·6% of 340 patients treated with streptokinase and 17·8% of 320 given herapin (P=0·011). Reinfarction in hospital after the 24-hour period of infusion occurred significantly less often in patients treated with streptokinase (P=0·036). Bleeding from puncture sites and pyrexia occurred more frequently during streptokinase treatment.After exclusion of those patients whose diagnosis was unconfirmed on retrospective assessment, the total hospital mortality rate was 19·0% of 357 patients treated with streptokinase and 27·4% of 339 treated with heparin (P=0·011). These results indicate that in recent myocardial infarction streptokinase was superior to heparin in reducing mortality and reinfarction rate during an average period of six weeks in hospital.     

Randomised controlled trial assessing the impact of a nurse delivered,flow monitored protocol for optimisation of circulatory status after cardiac surgery

Objective To assess whether a nurse led, flow monitored protocol for optimising circulatory status in patients after cardiac surgery reduces complications and shortens stay in intensive care and hospital.Design Randomised controlled trial.Setting Intensive care unit and cardiothoracic unit of a university teaching hospital.Participants 174 patients who underwent cardiac surgery between April 2000 and January 2003.Interventions Patients were allocated to conventional haemodynamic management or to an algorithm guided by oesophageal Doppler flowmetry to maintain a stroke index above 35 ml/m².Results 26 control patients had postoperative complications (two deaths) compared with 17 (four deaths) protocol patients (P = 0.08). Duration of hospital stay in the protocol group was significantly reduced from a median of nine (interquartile range 7-12) days to seven (7-10) days (P = 0.02). The mean duration of hospital stay was reduced from 13.9 to 11.4 days, a saving in hospital bed days of 18% (95% confidence interval -12% to 47%). Usage of intensive care beds was reduced by 23% (-8% to 59%).Conclusion A nurse delivered protocol for optimising circulatory status in the early postoperative period after cardiac surgery may significantly shorten hospital stay.     

Survey of 3765 cardiopulmonary resuscitations in British hospitals (the BRESUS Study): methods and overall results.

OBJECTIVE--To determine the circumstances, incidence, and outcome of cardiopulmonary resuscitation in British hospitals. DESIGN--Hospitals registered all cardiopulmonary resuscitation attempts for 12 months or longer and followed survival to one year. SETTING--12 metropolitan, provincial, teaching, and non-teaching hospitals across Britain. SUBJECTS--3765 patients in whom a resuscitation attempt was performed, including 927 in whom the onset of arrest was outside the hospital. MAIN OUTCOME MEASURE--Survival after initial resuscitation, at 24 hours, at discharge from hospital, and at one year, calculated by the life table method. RESULTS--There were 417 known survivors at one year, with 214 lost to follow up. By life table analysis for every eight attempted resuscitations there were three immediate survivors, two at 24 hours, 1.5 leaving hospital alive, and one alive at one year. Survival at one year was 12.5% including out of hospital cases and 15.0% not including these cases. Each hospital year averaged 30 survivors at one year: three who had an arrest outside hospital, seven who had one in the accident and emergency department, seven in the cardiac care unit, 10 in the general wards, and three in other, non-ward areas. Within the hospitals survival rates were best in those who had an arrest in the accident and emergency department, the cardiac care unit, or other specialised units. Outcome varied 12-fold in subgroups defined by age, type of arrest, and place of arrest. CONCLUSION--71% of the mortality at one year in patients undergoing attempted resuscitation occurred during the initial arrest. Hospital resuscitation is life saving and cost effective and warrants appropriate attention, training, coordination, and equipment.     

Terminal cancer care and patients' preference for place of death: a prospective study.

OBJECTIVE--To assess the preference of terminally ill patients with cancer for their place of final care. DESIGN--Prospective study of randomly selected patients with cancer from hospital and the community who were expected to die within a year. Patients expected to live less than two months were interviewed at two week intervals; otherwise patients were interviewed monthly. Their main carer was interviewed three months after the patient''s death. SETTING--District general hospital, hospices, and patients'' homes. MAIN OUTCOME MEASURE--Stated preferred place of final care; actual place of death; reason for final hospital admission for those in hospital; community care provision required for home care. RESULTS--Of 98 patients approached, 84 (86%) agreed to be interviewed, of whom 70 (83%) died during the study and 59 (84%) stated a preferred place of final care: 34 (58%) wished to die at home given existing circumstances, 12 (20%) in hospital, 12 (20%) in a hospice, and one (2%) elsewhere. Their own home was the preferred place of care for 17 (94%) of the patients who died there, whereas of the 32 patients who died in hospital 22 (69%) had stated a preference to die elsewhere. Had circumstances been more favourable 67% (41) of patients would have preferred to die at home, 16% (10) in hospital, and 15% (9) in hospice. CONCLUSION--With a limited increase in community care 50% more patients with cancer could be supported to die at home, as they and their carers would prefer.     

Open access fibresigmoidoscopy: a comparative audit of efficacy

A total of 541 open access referrals for fibresigmoidoscopy over five years were compared with 495 hospital initiated procedures during the same period. The number of open access fibresigmoidoscopies doubled during the five years but diagnostic yield remained unchanged at about 40% and was similar to that of the hospital initiated procedures. Colorectal carcinoma was seen in 64 open access patients compared with 47 hospital referred patients, the proportion of Dukes''s type A lesions being similar (34%) in both groups. Polyps, colitis, and diverticular disease were equally common in open access and hospital referred patients. Fibresigmoidoscopy failed to detect disease in only 12 patients (1·2%) and the procedure was unsatisfactory in only 54. Referral was considered justified in 475 (88%) open access patients, and only 54 (17%) patients with normal appearances at endoscopy required further investigations.Diagnostic yields were low (19%; 30/156 cases) in open access patients under 40 and in patients with abdominal pain, constipation, or abdominal pain with constipation (0-17%). Most of these young patients presumably suffer from the irritable bowel syndrome and do not justify fibresigmoidoscopy. In contrast, there was a high diagnostic yield (90-100%) in patients of all ages referred for diarrhoea and rectal bleeding, altered blood from the rectum, and rectal bleeding associated with abdominal pain.Open access fibresigmoidoscopy is an effective service that should be freely available to general practitioners.     

Cardiopulmonary Resuscitation in a University Hospital: An Analysis of Survival and Cost

A cost analysis and study were done of patient survival after inhospital cardiopulmonary resuscitation during one year at a university hospital. The immediate survival rate in 128 patients was 52 percent. Survival to discharge and six-month survival rates were 19 percent and 15.6 percent, respectively. In all, 23 patients (18 percent) had multiple arrests (two to four per patient) during the same hospital stay. Immediate and six-month survival rates in this group were 52 percent (12 patients) and 9 percent (two patients), respectively. Gender or location where cardiopulmonary arrests occurred in the hospital did not influence survival. The cost of a Code Blue (direct expenses only) was $366. We conclude that the outcome following resuscitation at this university hospital compares favorably with the experience of others, and that the direct cost is modest in relation to the results obtained.     

Results of Early Mobilization and Discharge after Myocardial Infarction

A total of 342 patients with acute myocardial infarction who were admitted to a coronary care unit are reviewed to assess the results of early mobilization and discharge. The mean duration of admission was 8·4 days and 89% of the survivors were discharged from hospital by the tenth day. The inpatient mortality was 15·5%. An additional 6·7% died during the six weeks'' follow-up period, giving a total mortality of 22·2%. Altogether, 7·6% of patients were readmitted. Venous thromboembolic phenomena occurred in 3·5% during the inpatient period. Of patients who were eligible 62% were back at work five months after their myocardial infarction. We think the results justify a short hospital admission period for acute myocardial infarction.     

Change of glycosaminoglycan in pus of patients with purulent pleurisy

The glycosaminoglycan content in pus from patients with purulent pleurisy was studied. The uronic acid content rose in the first 4 hospital days, continued at a high level during hospital days 5-8, and then fell to a low level after 9 hospital days. Four glycosaminoglycans were isolated from the preparation; they were identified as hyaluronic acid, chondroitin 4-sulfate, chondroitin 6-sulfate, and dermatan sulfate. Hyaluronic acid was the main component and its relative proportion increased with increasing hospital days. The relative proportions of chondroitin 4-sulfate and chondroitin 6-sulfate were low during the first 4 day and during Days 10-21, whereas they were high during Days 5-9. The proportion of dermatan sulfate was high during the early hospital days, and thereafter decreased with increasing hospital days.     

Complications of tonsillectomy and adenoidectomy in 9409 children observed overnight.

In attempts to minimize the cost of health care, physicians are reducing the duration of hospital stay. Traditionally, at the Hospital for Sick Children, Toronto, otherwise healthy children undergoing adenoidectomy, tonsillectomy or adenotonsillectomy have been admitted the morning of surgery and discharged from hospital at 7 am the next day. The nursing records of 9409 patients aged 17 years or less who were managed in this way between 1980 and 1984 were reviewed to determine the occurrence of complications during the observation period. A total of 202 patients (2.15%) bled during the observation period. Of the 202, 6 (0.06% of all the patients) required a second general anesthetic for hemostasis; 1 of these 6 patients and 5 others required blood transfusions. Discharge was delayed for 42 patients (0.45% of all the patients) because of postoperative bleeding and for 57 patients (0.6%) for a variety of other reasons. Delayed discharge for reasons other than hemorrhage was more frequent among children less than 2 years of age and those over 12 years of age. The authors concluded that children undergoing adenoidectomy could safely be discharged the same day after 6 hours of observation following surgery. However, as a substantial number of children bled from the tonsillar fossa more than 6 hours after surgery, the efficacy of periodic examination of the oral cavity during the observation period in reducing the rate of hemorrhage after 6 hours must be evaluated before a same-day discharge program is established for children undergoing adenotonsillectomy.     

Identifying acute coronary syndrome patients approaching end-of-life

Background

Acute coronary syndrome (ACS) is common in patients approaching the end-of-life (EoL), but these patients rarely receive palliative care. We compared the utility of a palliative care prognostic tool (Gold Standards Framework (GSF)) and the Global Registry of Acute Coronary Events (GRACE) score, to help identify patients approaching EoL.

Methods and Findings

172 unselected consecutive patients with confirmed ACS admitted over an eight-week period were assessed using prognostic tools and followed up for 12 months. GSF criteria identified 40 (23%) patients suitable for EoL care while GRACE identified 32 (19%) patients with ≥10% risk of death within 6 months. Patients meeting GSF criteria were older (p = 0.006), had more comorbidities (1.6±0.7 vs. 1.2±0.9, p = 0.007), more frequent hospitalisations before (p = 0.001) and after (0.0001) their index admission, and were more likely to die during follow-up (GSF+ 20% vs GSF- 7%, p = 0.03). GRACE score was predictive of 12-month mortality (C-statistic 0.75) and this was improved by the addition of previous hospital admissions and previous history of stroke (C-statistic 0.88).

Conclusions

This study has highlighted a potentially large number of ACS patients eligible for EoL care. GSF or GRACE could be used in the hospital setting to help identify these patients. GSF identifies ACS patients with more comorbidity and at increased risk of hospital readmission.     

A multicentre observational study of presentation and early assessment of acute stroke

ObjectiveTo investigate delays in the presentation to hospital and evaluation of patients with suspected stroke.DesignMulticentre prospective observational study.Setting22 hospitals in the United Kingdom and Dublin.Participants739 patients with suspected stroke presenting to hospital.ResultsThe median age of patients was 75 years, and 400 were women. The median delay between onset of symptoms and arrival at hospital was 6 hours (interquartile range 1 hour 48 minutes to 19 hours 12 minutes). 37% of patients arrived within 3 hours, 50% within 6 hours. The median delay for patients using the emergency service was 2 hours 3 minutes (47 minutes to 7 hours 12 minutes) compared with 7 hours 12 minutes (2 hours 5 minutes to 20 hours 37 minutes) for referrals from general practitioners (P<0.0001). Use of emergency services reduced delays to hospital (odds ratio 0.45, 95% confidence interval 0.23 to 0.61). The median time to evaluation by a senior doctor was 1 hour 9 minutes (interquartile range 33 minutes to 1 hour 50 minutes) but was undertaken in only 477 (65%) patients within 3 hours of arrival. This was not influenced by age, sex, time of presentation, mode of referral, hospital type, or the presence of a stroke unit. Computed tomography was requested within 3 hours of arrival in 166 (22%) patients but undertaken in only 60 (8%).ConclusionDelays in patients arriving at hospital with suspected stroke can be reduced by the increased use of emergency services. Over a third of patients arrive at hospital within three hours of stroke; their management can be improved by expediting medical evaluation and performing computed tomography early.

What is already known on this topic

Delay in presentation and assessment of patients with suspected stroke prevents the possible benefits from thrombolysis being achievedLittle is known about the presentation and early management of patients with acute stroke in the United Kingdom

What this study adds

Most patients with suspected stroke in the United Kingdom arrive at hospital within six hours of the onset of symptomsNot all patients are evaluated by a senior doctor within three hours of arrival at hospital and most do not undergo computed tomographyThe potential for thrombolysis in patients with acute stroke can be improved significantly by greater use of emergency services and expediting evaluation and investigations by doctors     

Hypernatraemic dehydration in patients in a large hospital for the mentally handicapped.

OBJECTIVE--To determine the prevalence of hypernatraemic dehydration and to assess the hydration and nutritional state of patients in a large hospital for the mentally and physically handicapped; also to assess the efficacy of an intervention programme to reduce the prevalence of hypernatraemic dehydration in the hospital. DESIGN--Prospective study of patients admitted with hypernatraemic dehydration from a large hospital for mentally and physically handicapped patients (hospital A) to a district general hospital between 1986 and 1988. In 1986 the hydration and nutritional state of a random sample of patients from hospital A was compared with a random sample of patients from a small hospital for the physically and mentally handicapped (hospital B) and with control groups from the community. The hydration of the patients from hospital A examined in 1986 was reassessed in 1988. PATIENTS--12 Patients were admitted from hospital A to the district general hospital during 1986-8 (seven women, five men; age range 29-82). In 1986, 72 patients were randomly selected for the assessment of hydration and nutritional state from hospital A, 33 who required help with feeding and 39 who could feed independently. Fifty patients were similarly selected from hospital B, half of them requiring help with feeding. In 1988 the hydration state of 60 of the 72 patients from hospital was reassessed. Control values were taken from two published studies. INTERVENTIONS--In 1987 nursing staff in hospital A were asked to provide between 2.5 and 3.0 litres of fluid daily for all patients. The use of hypertonic enemas was discontinued, and the ratio of staff to patients was increased. MAIN OUTCOME MEASURES--Serum concentrations of urea and electrolytes (hydration) and body mass index (nutritional state). RESULTS--Of the 10 patients admitted with hypernatraemic dehydration from hospital A to the district general hospital in 1986, four died of intercurrent infection. No patients were admitted from hospital B with hypernatraemic dehydration during the same time. In 1986 the hydration and nutritional state of patients in hospital A were inferior to those in patients from hospital B and control subjects from the community (serum urea concentrations were 6.1 (SD 1.8) mmol/l v 5.5 (1.9) and 5.6 (0.4) mmol/l, respectively) 50% (36/72) of patients in hospital A had a body mass index less than or equal to 20 compared with 34% (17/50) of patients from hospital B and 12% (1141/9434) of control subjects). After the initiation of the preventive programme only one patient was admitted with hypernatraemic dehydration in each of the years 1987 and 1988. The mean serum urea concentration of the 60 patients who were reassessed in 1988 fell significantly between 1986 and 1988 from 6.1 (SD 1.8) mmol/l to 5.7 (2.1) mmol/l, the value in a control group matched for age and sex. CONCLUSIONS--Hypernatraemic dehydration, subclinical underhydration, and undernutrition were common in a large hospital for the mentally and physically handicapped. The problem of hypernatraemic dehydration was successfully dealt with by the hospital management team. Similar problems may be encountered in hospitals for patients who are mentally and physically handicapped and mentally ill, including psychogeriatric units.     

Puumala Hantavirus-Induced Hemorrhagic Fever with Renal Syndrome Must Be Considered across the Borders of Nephrology to Avoid Unnecessary Diagnostic Procedures

Background

Nephropathia epidemica (NE), a milder form of hemorrhagic fever with renal syndrome, is caused by Puumala virus and is characterized by acute kidney injury and thrombocytopenia.

Methods

A cross-sectional prospective survey of 456 adult patients with serologically confirmed NE was performed.

Results

Of the 456 investigated patients, 335 had received inpatient treatment. At time of admission to hospital, 72% of the patients had still an AKI and thrombocytopenia was present in 64% of the patients. The 335 patients were treated in 29 different hospitals and 6 of which had nephrology departments. 10 out of 335 patients received treatment in university hospitals and 63% of patients admitted themselves to hospital. Initially, the patients were admitted to 12 different clinical departments (29% of the patients were referred to a nephrology department) and during the course of the disease, 8% of the patients were transferred to another department in the same hospital and 3% were transferred to a nephrology department at another hospital. Regarding diagnostic procedures, in 28% of the inpatients computed tomography to exclude pulmonary embolism or due to severe gastrointestinal symptoms, lumbar puncture to exclude meningitis, magnetic resonance tomography of the brain owing to suspected stroke because of visual disorders, gastroscopy, or colonoscopy due to gastrointestinal symptoms was performed at time of admission to hospital.

Conclusions

NE must be considered by physicians across the borders of nephrology to avoid unnecessary diagnostic procedures especially in areas where NE is endemic.     

Improved prognosis since 1969 of myocardial infarction treated in a coronary care unit: lack of relation with changes in severity.

OBJECTIVE--To study changes from 1969 to 1983 in the prognosis of patients with acute myocardial infarction treated in a coronary care unit. DESIGN--Mortality follow up of all patients with definite acute myocardial infarction. SETTING--The coronary care unit of the Royal Melbourne Hospital, a tertiary referral centre. SUBJECTS--4253 Patients (3366 men, 887 women) admitted from 1969 to 1983. MAIN OUTCOME MEASURE--Mortality recorded at discharge from hospital and 12 months after admission. RESULTS--Details of clinical findings, history, electrocardiograms, arrhythmias, and radiological findings were recorded on admission. Mean ages were 63 for women and 57 for men, and women had haemodynamically more severe infarcts than men. In the later years patients were older and had less severe infarcts. Overall, hospital mortality in men was 16.7% in 1969-73 and 8.5% in 1979-83 and declined in all grades of the Norris and Killip infarct severity indices compared with a constant 19.2% in women. Even after adjustment for age and severity by logistic regression, hospital mortality fell in men by an average of 8% (95% confidence interval 4% to 11%) a year but remained constant in women. By 1983 male mortality was 60% that of women of similar age and comparable severity of infarction. Mortality of hospital survivors at 12 months declined by 7% (4% to 9%) a year in both sexes, even after adjustment for age and severity, with a male to female mortality ratio of about 0.8. New indices were derived to predict mortality in hospital and at 12 months. CONCLUSION--The observed declines in mortality cannot be explained by changes in severity of infarction or in prognostic characteristics of patients.     

Vaccination of prostatectomized prostate cancer patients in biochemical relapse,with autologous dendritic cells pulsed with recombinant human PSA

This study was conducted in prostate cancer patients in biochemical relapse after radical prostatectomy, to assess the feasibility, safety, and immunogenicity of therapeutic vaccination with autologous dendritic cells (DCs) pulsed with human recombinant prostate-specific antigen (PSA) (Dendritophage-rPSA). Twenty-four patients with histologically proven prostate carcinoma and an isolated postoperative rise of serum PSA (>1 ng/ml to 10 ng/ml) after radical prostatectomy were included. The patients received nine administrations of PSA-loaded DCs by combined intravenous, subcutaneous, and intradermal routes over 21 weeks. Postbaseline blood tests were performed at months 1, 3, 6, 9, and 12 (PSA levels), at months 6 and 12 (circulating prostate cancer cells), at month 6 (anti-PSA IgG and IgM antibodies), and at up to eight time points before, during, and after immunization (PSA-specific T cells). Circulating prostate cancer cells detected in six patients at baseline were undetectable at 6 months and remained undetectable at 12 months. Eleven patients had a postbaseline transient PSA decrease on one to three occasions, predominantly occurring at month 1 (7 patients) or month 3 (2 patients). Maximum PSA decrease ranged from 6% to 39%. PSA decrease on at least one occasion was more frequent in patients with low Gleason score (p=0.016) at prostatectomy and with positive skin tests at study baseline (p=0.04). PSA-specific T cells were detected ex vivo by ELISpot for IFN- in 7 patients before vaccination and in 11 patients after vaccination. Of the latter 11 patients, 5 had detectable T cells both before and during the vaccination period, 4 only during the vaccination period, while 2 patients could for technical reasons not be assessed prevaccination. No induction of anti-PSA IgG or IgM antibodies was detected. There were no serious adverse events or otherwise severe toxicities observed during the trial. Immunization with Dendritophage-rPSA was feasible and safe in this cohort of patients. An immune response specific for PSA could be detected in some patients. A notable effect was the disappearance of circulating prostate cells in all patients who were RT-PCR positive before vaccination.Scientific correspondence should be addressed to B.
