|---|---|
Are primary care physicians ready to practice in a consumer-driven environment? | Many primary care physicians report low knowledge of CDHPs, limited readiness to advise patients on issues of cost and medical budgeting, and minimal trust in quality-of-care information. |
Can a public health intervention improve awareness and health-seeking behaviour for glaucoma? | This study has shown a significant increase in awareness from using different kinds of media and has shown radio to be the most effective in our target community. Although the campaign has raised awareness, this study has not shown a change in health-seeking behaviour. |
Is ritual circumcision a risk factor for neonatal urinary tract infections? | There was a higher preponderance of UTI among male neonates. Its incidence peaked during the early post-circumcision period, as opposed to the age-related rise in females. UTI seems to occur more frequently after traditional circumcision than after physician-performed circumcision. We speculate that changes in the haem... |
Depression-related variation in brain morphology over 3 years: effects of stress? | This study supports findings from animal studies of neuroplastic stress-related processes that occur in the hippocampus, amygdala, dorsomedial prefrontal cortex, dorsolateral prefrontal cortex, and anterior cingulum during depressive episodes. |
Controlling firearms use in Australia: has the 1996 gun law reform produced the decrease in rates of suicide with this method? | The implemented restrictions may not be responsible for the observed reductions in firearms suicide. Data suggest that a change in social and cultural attitudes could have contributed to the shift in method preference. |
Is there an association between the rating of illness and injury severity and the experience of emergency medical physicians? | The results demonstrate that emergency physicians with less rescue experience rated the severity of illness or injury relatively lower in comparison to colleagues who had worked in the pre-hospital setting for many years. |
Are health-care relationships important for mammography adherence in Latinas? | Understanding the factors that impact Latinas' mammography adherence may inform intervention strategies. Efforts to improve Latina's satisfaction with physicians by building trust may lead to increased use of necessary mammography. |
Does isoflurane enhance rhinovirus replication and virus-induced cytokine secretion in airway epithelial cells? | Isoflurane treatment showed no additional effects with RV on ICAM-1 expression, secretion of IL-6 and IL-8, and viral titer in A549 cells. These results suggest that isoflurane itself may not increase further RV infections, inflammations, and viral replication in patients with a viral URI. |
Are women more sensitive to a pre-curarization dose of rocuronium than men? | Pre-curarization with rocuronium 0.03 mg/kg affected men and women equally. Nor was the incidence and the severity of muscle weakness affected by gender. |
The darkening cloud of diabetes: do trends in cardiovascular risk management provide a silver lining? | During our period of study, there was an increase in the utilization of evidenced-based drug therapies in people with diabetes and reductions in cardiovascular-related hospitalizations. Despite this, we observed no change in all-cause mortality. |
Digital ischemia in a gardener: is rose cutting a vascular risk factor? | In the presence of a radial artery aneurysm an occupational and recreational trauma history should be sought after. |
Do major depressive disorder and dysthymic disorder confer differential risk for suicide? | Our results demonstrate the importance of both chronicity and severity of depression in terms of predicting increased suicide risk. Among the various forms of depressive illness examined, only recurrent MDD appeared to confer greater risk for suicide. |
Automobile versus pedestrian injuries: does gender matter? | Gender plays a significant role in the incidence of pelvic and tibial fractures but has no effect on survival or ICU stay, but male patients in the age group 15-65 years had a significantly longer hospital stay. |
Late recurrence after surgery for cholangiocarcinoma: implications for follow-up? | Long-term follow-up after resection of cholangiocarcinoma is needed because late recurrence after 5 years occurs. The mortality rate between 5 and 10 years after resection of cholangiocarcinoma ranges from 6% to 43% in different series. Early detection of local recurrence may give an opportunity for further surgical re... |
Is there a unique measuring method to assess obesity? | Determination of body composition would be important concerning the follow-up of biochemical changes occurring in the body during the course of both epidemiological studies and nutritional interventions. |
Do apparent diffusion coefficient measurements predict outcome in children with neonatal hypoxic-ischemic encephalopathy? | ADC values in normal-appearing basal ganglia and brain stem correlated with outcome, independently of all MR imaging findings including those of DWI. ADC values in visibly abnormal brain tissue on DWI did not show a predictive value for outcome. |
Can emergency medical service staff predict the disposition of patients they are transporting? | Staff in one UK ambulance service showed reasonable accuracy when predicting the likelihood of admission of patients they transport. They correctly identified most patients who would be able to leave. Further work is needed to support these findings and ensure that EMS staff safely triage patients to alternative destin... |
A 50-g glucose challenge test: is there any diagnostic cut-off? | A 50-g glucose challenge test may be used as a diagnostic test when the value is>or = 250 mg/dL. The present data suggested that the value of glucose screening of>or = 145 mg/dL can be used as a threshold for a positive test in the low risk women. |
Does physical activity during pregnancy reduce the risk of gestational diabetes among previously inactive women? | Results suggest that physical activity during pregnancy is associated with lower risk for gestational diabetes among previously inactive women. |
Are cesarean deliveries more likely for poorly educated parents? | Mothers with little education were consistently more likely to deliver by cesarean section than highly educated women, even when their partner's level of education was taken into account. Effective interventions aimed at reducing cesarean delivery rates in women of lower social class should be a priority for national h... |
Cortical mastoidectomy in quiescent, tubotympanic, chronic otitis media: is it routinely necessary? | Mastoidotympanoplasty was not found to be superior to tympanoplasty alone over a short term follow-up period. Hence, it may not be necessary to undertake routine mastoid exploration at this stage of disease. |
Is tonic immobility the core sign among conventional peritraumatic signs and symptoms listed for PTSD? | Our study provides good reason to conduct more research on tonic immobility in PTSD with other samples and with different time frames in an attempt to replicate these stimulating results. |
Does a functional activity programme improve function, quality of life, and falls for residents in long term care? | A programme of functional rehabilitation had minimal impact for elderly people in residential care with normal cognition but was not beneficial for those with poor cognition. Trial registration Australian Clinical Trials Register ACTRN12605000667617. |
Are energy dense diets also nutrient dense? | This study suggests that ED may influence the ND of the diet depending on whether energy containing beverages are included or excluded in the analysis. |
Can early neurosonology predict outcome in acute stroke? | Transcranial ultrasound provides important information on prognosis in patients with acute stroke. |
Collecting system involvement by renal tumor: are CT measurements reliable enough? | The trend of NSS and ablative techniques stressed out the importance of pretreatment measurements of the distance between the tumor and the CS. This study as performed on radical nephrectomy specimens points out the overestimated proximity of the tumor to the CS. These data if confirmed by other studies, may play a rol... |
Spontaneous pneumomediastinum: is a chest X-ray enough? | SPM is a rare entity that should be considered in patients with pleuritic chest pain. Treatment is supportive, and if no clues for esophageal rupture are present, investigations other than chest X-ray are probably not warranted. It is safe to discharge the patient within 24 hours provided that symptomatic improvement i... |
Doctor, is my teddy bear okay? | Our results indicate that by initiating a controlled pain-free encounter with the medical environment in the form of a "Teddy Bear Hospital", we can reduce children's anxiety about hospitalization. |
Do the malnutrition universal screening tool (MUST) and Birmingham nutrition risk (BNR) score predict mortality in older hospitalised patients? | The MUST score, but not the BNR, is able to predict increased mortality in older hospitalised patients. |
Are migraineur women really more vulnerable to stress and less able to cope? | We consider that, these outcomes may emphasize the necessity to be careful when using negative expressions about stress relating to migraineurs. Further comprehensive studies are required considering the multiple triggers of the disease in various cultural contexts. |
Prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae genital infections in a publicly funded pregnancy termination clinic: empiric vs. indicated treatment? | We found a comparatively high prevalence rate of chlamydia-positive patients (11.4%) in our publicly funded pregnancy termination clinic. Because of infrequent follow-up in this patient population, we suggest screening and providing the epidemiologic treatment for CT genital infection for all women undergoing a same-da... |
Chronic inflammatory changes in the anal transition zone after stapled ileal pouch-anal anastomosis: is mucosectomy a superior alternative? | Preservation of the ATZ, even in presence of persistent inflammation, confers improved continence, better functional outcomes, and superior quality of life. |
Unsuccessful temporomandibular joint arthroscopy: is a second arthroscopy an acceptable alternative? | Arthroscopic surgery is a reliable and effective procedure for temporomandibular joint dysfunction that improves pain and mouth opening, with the advantages of being minimally invasive and repeatable. Repeat arthroscopic surgery, with a proven history of fewer complications, can be attempted before open arthrotomy. |
Is the use of arch bars or interdental wire fixation necessary for successful outcomes in the open reduction and internal fixation of mandibular angle fractures? | The use of Erich arch bars or interdental wire fixation to assist with MMF during the open reduction and internal fixation of noncomminuted mandibular angle fractures treated in Champy fashion is not always necessary for successful outcome. |
Is psychotherapy a reliable alternative to pharmacotherapy to promote the mental health of infertile women? | Psychotherapy, such as group CBT, was superior to or at least as effective as pharmacotherapy to promote the well being of depressed infertile women. |
Are there specific prognostic factors for acute coronary syndrome in patients over 80 years of age? | In elderly patients admitted into hospital with acute coronary syndrome, geriatric parameters do not seem to affect prognosis which is dominated by cardiac variables. |
Histamine 1 receptor antagonist in symptomatic treatment of renal colic accompanied by nausea: two birds with one stone? | Dimenhydrinate, which is an ethanolamine group H1 receptor blocker, appeared to be effective compared with the placebo in relieving renal colic pain and nausea and vomiting symptoms in patients. Comparative studies with other analgesics will be useful for determining how to use this agent for analgesic purposes in rena... |
Transfusions in the less severely injured: does age of transfused blood affect outcomes? | In a mild to moderately injured intensive care unit patient cohort, the receipt of blood stored beyond 2 weeks was independently associated with mortality, renal failure, and pneumonia. The deleterious effect of older blood on patient outcome does not appear to be limited to the severely injured. |
Does nephrectomy of failed allograft influence graft survival after re-transplantation? | Nephrectomy of a failed allograft does not seem to significantly influence the survival of a subsequent graft. |
An uncommon case of failed suicide in a 94-year-old woman: "masked" depression or rational decision? | The unusual features of this case relate to: 1) the person's female gender and very advanced age; 2) her apparently "successful aging" condition; 3) the violent method and unusual means she used; 4) the suicide note written several days beforehand. |
Anticoagulant drugs in noncompaction: a mandatory therapy? | Noncompaction of the left ventricular myocardium, by itself, does not seem to be a risk factor for stroke or embolic results, so there is no indication for oral anticoagulant therapy. |
Can favorable psychosocial work conditions and high work dedication protect against the occurrence of work-related musculoskeletal disorders? | This study shows that job resources are not only important for promoting work dedication, but may also moderate the negative impact of high job demands on the risk of work-related musculoskeletal disorders. With respect to social support, the question is raised of whether this can also work negatively. The results of t... |
High versus standard-volume haemofiltration in hyperdynamic porcine peritonitis: effects beyond haemodynamics? | In this porcine model of septic shock early HVHF proved superior in preventing the development of septic hypotension. However, neither of haemofiltration doses was capable of reversing the progressive disturbances in microvascular, metabolic, endothelial and lung function, at least within the timeframe of the study and... |
Does odour cross contamination alter olfactory thresholds in certain odours? | There is limited cross contamination with ACE and EUC, which is avoided by specifying presentation order as: PEA, MER, ACE, EUC. Odours PEA, MER, ACE and EUC are recommended for olfactory testing. |
Does peak nasal inspiratory flow relate to peak expiratory flow? | PNIF is a useful method to study nasal patency in both primary and secondary care to aid diagnosis of nasal disease, but low values of PNIF have to be confirmed by a study of the PEF as PNIF low values may be an expression of low ventilatory activity rather than an expression of nasal obstruction. |
Value of [18F]fluorodeoxyglucose positron emission tomography in the management of follicular lymphoma: the end of a dilemma? | Positron emission tomography at staging is able to substantially change treatment strategy in an important proportion of patients with FL. Persisting PET positivity after treatment predicts for a high risk of an early relapse and can identify patients with poor prognosis. |
Does controlled ovarian stimulation prior to chemotherapy increase primordial follicle loss and diminish ovarian reserve? | This animal study indicates that ovarian stimulation before administration of Cy does not adversely affect ovarian reserve post-treatment. These results provide support for the safety of fertility preservation using ovarian stimulation and IVF-embryo cryopreservation procedures prior to chemotherapy. |
Can you use a sequential sample of patients as a substitute for a full practice audit? | A rate of mammography screening based on a sequential sample can reasonably approximate the actual rate of mammography screening that would be found based on a full practice audit. |
Do psychological attributes matter for adherence to antihypertensive medication? | High sense of coherence may influence antihypertensive medication-adherence behaviour. Aspects characterizing this psychological attribute, such as knowledge (comprehensibility), capacity (manageability), and motivation (meaningfulness) may be important determinants of adherence behaviour for asymptomatic illnesses, su... |
Does the addition of ketorolac and dexamethasone to lidocaine intravenous regional anesthesia improve postoperative analgesia and tourniquet tolerance for ambulatory hand surgery? | IVRA with lidocaine and with the inclusion of ketorolac and dexamethasone provides effective perioperative analgesia for patients undergoing ambulatory hand surgery, when compared to the use of lidocaine alone or lidocaine with ketorolac IVRA. |
Primary antiphospholipid syndrome evolving into systemic lupus erythematosus: may antinucleosome antibodies be predictive? | A significant proportion of PAPS patients displayed medium-high titre anti-NCS, suggesting that the autoimmune response against chromatin may be a relevant event not only in patients with SLE. Further studies are warranted to explore the predictive value of anti-NCS with respect to the evolution from PAPS to SLE. |
Is a circular polypropylene mesh appropriate for application at the esophageal hiatus? | A circular heavy-weight polypropylene mesh seems to be appropriate for the application at the esophageal hiatus in terms of safety and stability. This means that it is characterized by a position-stable centered fixation around the esophagus without a tendency toward stenosis, migration, or erosion. |
Palpable breast masses with probably benign morphology at sonography: can biopsy be deferred? | The negative predictive value of sonography for palpable breast masses with probably benign morphology is high (99.4%). Therefore, short-term imaging follow-up can be an acceptable alternative to immediate biopsy, similar to the management of nonpalpable probably benign lesions (BI-RADS category 3). |
Assessing change in clinical teaching skills: are we up for the challenge? | It is possible to measure feedback skills in a clinical setting. Although traditional outcome measures show a significant effect, demonstrating change in teaching behaviors used in practice will require larger scale studies than typically undertaken currently. |
Should we revascularize before implanting a pacemaker? | Patients who have concomitant severe conduction disturbances and significant coronary disease may well receive a pacemaker before a revascularization procedure. Our data shows that coronary revascularization has little, if any, impact on returning to normal AV conduction. |
Transcription factor PDX-1 in human colorectal adenocarcinoma: a potential tumor marker? | These data argue for further evaluation of PDX-1 as a biomarker for colorectal cancer. |
Inhaled albuterol and oral prednisone therapy in hospitalized adult asthmatics. Does aminophylline add any benefit? | Our results suggest that aminophylline therapy does not add significant benefit to other standard therapies in hospitalized adult asthmatic patients. Because of the risks and cost of aminophylline treatment in the hospital setting, further research is needed to determine if there are subgroups of adult asthmatics who m... |
Can prepregnancy care of diabetic women reduce the risk of abnormal babies? | Tight control of the maternal blood glucose concentration in the early weeks of pregnancy can be achieved by the prepregnancy clinic approach and is associated with a highly significant reduction in the risk of serious congenital abnormalities in the offspring. Hypoglycaemic episodes do not seem to lead to fetal malfor... |
Are readmissions avoidable? | Differences were apparent in the extent of avoidability of readmissions in different groups of admissions. However, assessors rated only 49.3% of the group with the highest proportion of avoidable admissions (surgical readmissions at 0-6 days) as avoidable. The remainder were thought to be unavoidable except for 2%, wh... |
CT of intraabdominal desmoid tumors: is the tumor different in patients with Gardner's disease? | No CT characteristics, such as attenuation values, margins, and response to the contrast material, were found that would enable differentiation between isolated intraabdominal desmoids and those associated with Gardner's disease. Desmoid tumors associated with Gardner's syndrome tend to occur in the mesentery and abdom... |
Blunt splenic trauma in adults: can CT findings be used to determine the need for surgery? | Our results show that CT findings cannot be used to determine reliably which patients require surgery and which patients can be treated conservatively. Even patients with splenic parenchymal injuries of CT grade III, IV, and V and with CT-based scores of 2.5 or higher can be successfully treated conservatively if the c... |
Is intramuscular mivacurium an alternative to intramuscular succinylcholine? | Although ventilatory depression preceded twitch depression, both occurred later with intramuscular mivacurium than would be expected after intravenous mivacurium or intramuscular succinylcholine. The authors speculate that the onset of intramuscular mivacurium is too slow to treat laryngospasm or to facilitate routine ... |
Does halothane interfere with the release, action, or stability of endothelium-derived relaxing factor/nitric oxide? | The authors' data demonstrate that halothane does not interfere with endothelial cell release of EDRF/NO and its smooth muscle cell relaxation but seems to modify either EDRF/NO half-life or its activated redox form. |
Is age-related maculopathy associated with cataracts? | These data suggest a possible commonly shared pathogenesis between nuclear sclerotic cataract and age-related maculopathy. |
Are antioxidants or supplements protective for age-related macular degeneration? | The data suggest a protective effect for AMD of high plasma values of alpha-tocopherol. An antioxidant index, composed of plasma ascorbic acid, alpha-tocopherol, and beta-carotene, was also protective. The use of vitamin supplements to prevent AMD is not supported by these data, which showed no protective effect of vit... |
Continuous ambulatory peritoneal dialysis: an option in the developing world? | The association of biomedical, socioeconomic, and psychosocial variables with high peritonitis rates has important implications for the selection of patients for CAPD in this setting. |
Midwifery defined by physicians, nurses and midwives: the birth of a consensus? | Some consensus on midwifery practice exists between physicians, nurses and midwives. In jurisdictions where opposition to midwives is strong, such consensus could serve as the starting point for the introduction of midwifery. |
Do coagulation screening tests detect increased generation of thrombin and plasmin in sick newborn infants? | Abnormal coagulation screens in sick newborn infants strongly support a diagnosis of DIC. However, normal screens do not exclude activation of the coagulation and fibrinolytic systems. |
Do anger and aggression affect carotid atherosclerosis? | Our results suggest that anger and, perhaps, aggression may be risk factors for cerebrovascular disease. |
Continuous spinal anesthesia: does low-dose plain or hyperbaric bupivacaine allow the performance of hip surgery in the elderly? | The authors conclude that 5 mg bupivacaine is too high a dose in the elderly to limit the sensory blockade at T10 and avoid hypotension. In elderly patients, this dose allowed surgery to be performed, provided that the sensory level reached T10. When the initial dose only affects lumbar dermatomes, a caudal direction o... |
Are ATP sensitive potassium channels involved in the pronounced antiarrhythmic effects of preconditioning? | In a similar model to that in which it has previously been shown that glibenclamide prevents the effect of preconditioning in reducing myocardial infarct size (suggesting involvement of K+ATP channels), the most pronounced antiarrhythmic effects of preconditioning (reduction in ventricular fibrillation; increase in sur... |
Is protected specimen brush a reproducible method to diagnose ICU-acquired pneumonia? | These findings argue for the poor repeatability of PSB in suspected IAP and question the yield of the 10(3) cfu/ml threshold. In attempting to diagnose IAP, the results of PSB must be interpreted with caution considering the intraindividual variability. |
Does the incidence, severity, or case fatality of stroke vary in southern England? | The SMRs for stroke in those aged under 65 in these three health districts reflect the incidence of stroke. Case fatality at three weeks does not vary between these districts and consequently would not be a sensitive indicator of the quality of care. This also suggests that differences in services between the districts... |
Interleukin-1 beta: a putative mediator of HPA axis hyperactivity in major depression? | It is suggested that constituents of the immune response (such as interleukin-1 beta) in major depression may contribute to HPA axis hyperfunction in that illness. |
Babesiosis in Washington State: a new species of Babesia? | WA1 is morphologically indistinguishable but antigenically and genotypically distinct from B. microti. Some patients elsewhere who were assumed to have been infected with B. microti may have been infected with WA1. Improved serodiagnostic and molecular techniques are needed for characterizing Babesia species and elucid... |
Preventive care for women. Does the sex of the physician matter? | Women are more likely to undergo screening with Pap smears and mammograms if they see female rather than male physicians, particularly if the physician is an internist or family practitioner. |
Are there differences in information given to private and public prenatal patients? | The one-on-one approach to health education in pregnancy usually used in the private setting may not facilitate addressing many topics believed to be important components of contemporary prenatal care. Providers of private prenatal care should initiate discussion of prenatal health education topics rather than relying ... |
Class A1 gestational diabetes: a meaningful diagnosis? | The diagnosis of class A1 gestational diabetes is not significantly associated with obstetric and perinatal morbidities. A nondiscriminating diagnostic test undermines the validity of population screening for glucose intolerance. |
Do women grieve after terminating pregnancies because of fetal anomalies? | Women who terminate pregnancies for fetal anomalies experience grief as intense as those who experience spontaneous perinatal loss, and they may require similar clinical management. Diagnosis of a fetal anomaly and subsequent termination may be associated with psychological morbidity. |
Does midline episiotomy increase the risk of third- and fourth-degree lacerations in operative vaginal deliveries? | Midline episiotomy is associated with an increased risk of third- and fourth-degree perineal lacerations in operative vaginal deliveries. |
Can further benefit be achieved by adding flosequinan to patients with congestive heart failure who remain symptomatic on diuretic, digoxin, and an angiotensin converting enzyme inhibitor? | These results indicate that additional symptomatic benefit can be attained by adding flosequinan to a therapeutic regimen already including a converting enzyme inhibitor. Because in the future most patients will fall into this category, flosequinan is a potential adjunctive agent in the management of severe congestive ... |
Does fish oil lower blood pressure? | There is a dose-response effect of fish oil on blood pressure of -0.66/-0.35 mm Hg/g omega-3 fatty acids. The hypotensive effect may be strongest in hypertensive subjects and those with clinical atherosclerotic disease or hypercholesterolemia. |
Does preconditioning protect the coronary vasculature from subsequent ischemia/reperfusion injury? | The protective effects of preconditioning do not extend to the coronary vasculature in this canine model: Preconditioning neither prevented the deterioration in resting myocardial perfusion nor blunted the loss in submaximal vasodilator reserve obs |
Cerebral blood flow and oxygen consumption in acute brain injury with acute anemia: an alternative for the cerebral metabolic rate of oxygen consumption? | In acute brain trauma with acute anemia, calculated arterio-jugular oxygen content difference and cerebral metabolic rate of oxygen consumption tend to be progressively lower, depending on the extent of anemia, which is in disagreement with coma scores. These changes in hemoglobin tend to have an inverse influence on c... |
Does implementing pulse oximetry in a critical care unit result in substantial arterial blood gas savings? | The implementation of pulse oximetry in this manner gives an idea how effective the technology will be in reducing the use of arterial blood gas determinations without guidelines for the use of pulse oximetry. As only a marginal decrease was observed in the total population of medical and surgical patients, and only on... |
Pharmacologic interventions after an LD50 cocaine insult in a chronically instrumented rat model: are beta-blockers contraindicated? | In this conscious animal model subjected to an LD50 IV cocaine insult, chlorpromazine and diazepam, previously shown to be of value in other animal models, had no effect on survival. Verapamil also did not affect outcome. Outcome was adversely affected by treatment with beta-blocking agents. |
Trends in adolescent smoking initiation in the United States: is tobacco marketing an influence? | Availability of cheaper cigarettes is not likely to be a cause of increased smoking initiation by adolescents. Although other influences cannot be ruled out, we suspect that the expanded tobacco marketing budget, with its increased emphasis on tactics that may be particularly pertinent to young people, affected adolesc... |
Can medical school-affiliated hospitals compete with private hospitals in the age of managed care? | Others have reported that MSAHs cannot compete with nonMSAHs in providing competitively priced care. The present study shows that for cholecystectomy, charges and length of hospital stay are comparable in MSAHs and nonMSAHs. This study supports the hypothesis that the leadership provided at United States medical school... |
Pulmonary contusion: are children different? | Although children and adults differ in regard to injury mechanism, their overall injury severity, associated injuries, and outcomes are quite similar. Thus, contrary to previous reports, children do not have a more favorable outcome after PC. |
Is color duplex surveillance of infrainguinal polytetrafluoroethylene grafts worthwhile? | Duplex surveillance of infrainguinal PTFE bypass grafts has a low yield and is inadequate at predicting continued bypass patency. |
Should obese patients lose weight before receiving a kidney transplant? | Outcome differences in obese renal transplant patients were primarily due to a higher mortality resulting from cardiac events. Obesity seems to have little effect on immunologic events, long-term graft function, or cyclosporine delivery. Aggressive pretransplant screening for ischemic heart disease is essential to iden... |
Qualitative assessment of liver for fatty infiltration on contrast-enhanced CT: is muscle a better standard of reference than spleen? | For the visual assessment of fatty liver, spleen is not an accurate reference standard on contrast-enhanced CT. However, fatty liver can be diagnosed on contrast-enhanced CT if liver appears less attenuating than muscle-a situation that occurs only if fatty infiltration is pronounced. |
Transurethral microwave thermotherapy in symptomatic benign prostatic hyperplasia: a possible association between androgen status and treatment result? | TUMT did not influence hormone levels. These observations suggest that androgen status may influence the final result of treatment. |
Can zinc prevent apoptosis of anterior keratocytes after superficial keratectomy? | At a significantly high dosage, zinc can prevent loss of superficial keratocytes to a greater extent than culture medium alone can. Moreover, zinc has the advantage of preserving the most anterior layer of keratocytes. Retention of these cells may prevent the reactive overproliferation that constitutes haze after photo... |
Do traditional symptoms of hypothyroidism correlate with biochemical disease? | In this sample, the number of hypothyroid symptoms reported was directly related to the level of TSH. The association was stronger when more symptoms were reported. Symptoms that had changed in the past year were more powerful than symptoms reported present at the time of testing. This suggests that traditional symptom... |
Does patient's gender affect the quality of clinical histories in primary care? | The analysis of the results suggests the need to improve the effectiveness of the PCCH as an instrument to achieve equality in individual care. |
Is the pediatric service coordinated? | There is no institutionalized coordination between HP and NCP. The greater the distance from the city, the greater the overload and the lower the coordination. There is a lack of institutional organization. |
Does laparoscopy increase the bacteriological risk of appendectomy? | A low risk of bacteraemia exists for both open and laparoscopic appendectomy. This risk did not appear to increase for laparoscopy. Conventional and laparoscopic surgical procedures led to positive peritoneal bacterial cultures after appendectomy in 33% of cases. |
Does EMG (dry needling) reduce myofascial pain symptoms due to cervical nerve root irritation? | EMG at tender points on myofascial bands tends to improve symptoms. Needling these points elicits motor endplate activity and twitches, and induces more relief than when needling random points. |
Do organic solvents induce changes in the dopaminergic system? | The data support the hypothesis that long-term exposure to organic solvents may increase the rate of dopamine synthesis in the brain without affecting the number of presynaptic terminals or postsynaptic dopamine receptors. |
