RESUMEN

Several interventions have been developed to support families living with parental mental illness (PMI). Recent evidence suggests that programmes with whole-family components may have greater positive effects for families, thereby also reducing costs to health and social care systems. This review aimed to identify whole-family interventions, their common characteristics, effectiveness and acceptability. A systematic review was conducted according to PRISMA 2020 guidelines. A literature search was conducted in ASSIA, CINAHL, Embase, Medline, and PsycINFO in January 2021 and updated in August 2022. We double screened 3914 abstracts and 212 papers according to pre-set inclusion and exclusion criteria. The Mixed Methods Appraisal Tool was used for quality assessment. Quantitative and qualitative data were extracted and synthesised. Randomised-control trial data on child and parent mental health outcomes were analysed separately in random-effects meta-analyses. The protocol, extracted data, and meta-data are accessible via the Open Science Framework ( https://osf.io/9uxgp/ ). Data from 66 reports-based on 41 independent studies and referring to 30 different interventions-were included. Findings indicated small intervention effects for all outcomes including children's and parents' mental health (dc = -0.017, -027; dp = -0.14, -0.16) and family outcomes. Qualitative evidence suggested that most families experienced whole-family interventions as positive, highlighting specific components as helpful, including whole-family components, speaking about mental illness, and the benefits of group settings. Our findings highlight the lack of high-quality studies. The present review fills an important gap in the literature by summarising the evidence for whole-family interventions. There is a lack of robust evidence coupled with a great need in families affected by PMI which could be addressed by whole-family interventions. We recommend the involvement of families in the further development of these interventions and their evaluation.

RESUMEN

BACKGROUND: Most evidence about what works in transitional care comes from small studies in single clinical specialties. We tested the hypothesis that exposures to nine recommended features of transitional healthcare were associated with better outcomes for young people with long-term conditions during transition from child-centred to adult-oriented health services. METHODS: This is a longitudinal, observational cohort study in UK secondary care including 374 young people, aged 14-18.9 years at recruitment, with type 1 diabetes (n = 150), cerebral palsy (n = 106) or autism spectrum disorder with an associated mental health problem (n = 118). All were pre-transfer and without significant learning disability. We approached all young people attending five paediatric diabetes centres, all young people with autism spectrum disorder attending four mental health centres, and randomly selected young people from two population-based cerebral palsy registers. Participants received four home research visits, 1 year apart and 274 participants (73%) completed follow-up. Outcome measures were Warwick Edinburgh Mental Wellbeing Scale, Mind the Gap Scale (satisfaction with services), Rotterdam Transition Profile (Participation) and Autonomy in Appointments. RESULTS: Exposure to recommended features was 61% for 'coordinated team', 53% for 'age-banded clinic', 48% for 'holistic life-skills training', 42% for 'promotion of health self-efficacy', 40% for 'meeting the adult team before transfer', 34% for 'appropriate parent involvement' and less than 30% for 'written transition plan', 'key worker' and 'transition manager for clinical team'. Three features were strongly associated with improved outcomes. (1) 'Appropriate parent involvement', example association with Wellbeing (b = 4.5, 95% CI 2.0-7.0, p = 0.001); (2) 'Promotion of health self-efficacy', example association with Satisfaction with Services (b = - 0.5, 95% CI - 0.9 to - 0.2, p = 0.006); (3) 'Meeting the adult team before transfer', example associations with Participation (arranging services and aids) (odds ratio 5.2, 95% CI 2.1-12.8, p < 0.001) and with Autonomy in Appointments (average 1.7 points higher, 95% CI 0.8-2.6, p < 0.001). There was slightly less recruitment of participants from areas with greater socioeconomic deprivation, though not with respect to family composition. CONCLUSIONS: Three features of transitional care were associated with improved outcomes. Results are likely to be generalisable because participants had three very different conditions, attending services at many UK sites. Results are relevant for clinicians as well as for commissioners and managers of health services. The challenge of introducing these three features across child and adult healthcare services, and the effects of doing so, should be assessed.

RESUMEN

BACKGROUND: Sperm banking is recommended for all men diagnosed with cancer where treatment is associated with risk of long-term gonadatoxicity, to offer the opportunity of fatherhood and improved quality of life. However, uptake of sperm banking is lower than expected and little is known about why men refuse. Our aims were to determine: (i) demographic and medical variables associated with decisions about banking and (ii) differences in quality of life between bankers and non-bankers at diagnosis (Time 1 (T1)) and 1 year later (Time 2 (T2)). METHODS: Questionnaires were completed by 91 men (response rate=86.67%) at T1 and 78 (85.71% response rate) at T2. RESULTS: In all, 44 (56.41%) banked sperm. They were younger and less likely to have children than non-bankers. In a subset of men who were not sure if they wanted children in the future (n=36), 24 banked sperm. Among this group, those who banked were younger, more satisfied with clinic appointments and less worried about the health of future children. At T2, there were no differences in quality of life between bankers and non-bankers. CONCLUSION: For those who are uncertain about future reproductive plans, decisions depend on their health on diagnosis and satisfaction with clinic care. We conclude that extra care should be taken in counselling younger men who may have given little consideration to future parenting. Results support previous findings that the role of the doctor is vital in facilitating decisions, especially for those who are undecided about whether they wanted children in the future or not.

RESUMEN

STUDY QUESTION: What medical and psychological variables predict why men with banked sperm do not return for semen analysis after their cancer treatment has ended? SUMMARY ANSWER: Men who decline the offer of semen analysis are less likely to have reported adverse side effects during cancer treatment, and have a more negative experience of banking sperm and a more negative attitude towards disposal of their stored semen than those who attend. WHAT IS KNOWN ALREADY: Previous authors have noted that male cancer survivors seem reluctant to have their fertility tested after their treatment has ended. Moreover, the utilization rates of banked sperm are very low (<10%) and the majority of samples are kept for many years without being used. STUDY DESIGN, SIZE AND DURATION: A cross-sectional study of 499 cancer survivors who were sent a questionnaire about their views on sperm banking, fertility and post-treatment semen analysis between April 2008 and December 2010. PARTICIPANTS AND SETTING: Men (aged 18-55 years) who had banked sperm in Sheffield and Nottingham (UK) prior to gonadotoxic treatment for cancer more than 5 years previously. MAIN RESULTS AND THE ROLE OF CHANCE: Completed questionnaires were received from 193 men (38.7% response rate) whose samples had been banked for 9.18 ± 3.70 years (range = 4.94-26.21) and whose current age was 35.08 ± 7.08 years (range = 21.58-54.34; mean ± SD). One-third (35.8%) had never attended for semen analysis. In multivariate analysis, the odds of not attending for semen analysis were significantly greater among men who did not experience adverse treatment side effects [odds ratio (OR) = 5.72, 95% confidence interval (CI) = 2.10-15.56], who reported a more negative experience of banking sperm (OR = 1.82, 95% CI = 1.17-2.82) and a more negative attitude to disposal of their stored semen (OR = 1.56, 95% CI = 1.01-2.42). LIMITATIONS AND REASONS FOR CAUTION: Only 38.7% of those eligible agreed to take part. We do not know the characteristics of men who declined to take part, if they agreed to attend semen analysis without completing the questionnaire or whether they had chosen to have semen analysis performed elsewhere (e.g. private sector). Some of the measures used (e.g. experience of banking sperm) relied on men's recall of events many years previously. WIDER IMPLICATIONS OF THE FINDINGS: New strategies are required to encourage these men to engage with fertility monitoring programmes if sperm banks are to be used cost-effectively and men are to be given appropriate fertility advice. STUDY FUNDING AND COMPETING INTERESTS: This paper was supported by funding from Cancer Research-UK to C.E., A.A.P. and R.R. (C481/A8141). The views expressed are those of the authors. No competing interests declared.

RESUMEN

Heparan sulfates have long been known to intracellularly accumulate in Alzheimer's disease neurons, where they colocalize with neurofibrillary tangles made of abnormally phosphorylated and aggregated tau protein. However, the reasons and consequences of the heparan sulfates accumulation in the Alzheimer's cells are not yet well understood. Previously, we showed that the neural heparan sulfate 3-O-sulfotransferase HS3ST2 is critical for the abnormal phosphorylation of tau in Alzheimer's disease-related tauopathy. Using cell models of tauopathy we showed that intracellular 3-O-sulfatated heparan sulfates interact with tau inducing its abnormal phosphorylation. However, it is unknown whether HS3ST2 expression induces the intracellular aggregation of tau in cells. Here, by using replicative pEBV plasmids, we engineered HEK293 cells to stably express HS3ST2 together with human tau carrying or not the P301S mutation. We show that HS3ST2 gain of function induces the cell autonomous aggregation of tau not only in cells expressing tauP301S, but also in cells expressing the wild type tau. Our engineered cells mimicked both the HS intracellular accumulation observed in neurons of Alzheimer's disease and the tau aggregation characteristic of tauopathy development and evolution. These results give evidence that the neural HS3ST2 plays a critical role in the cell autonomous self-aggregation of tau.

RESUMEN

BACKGROUND: Lung cancer is the most common cancer and smoking is the principal cause. Due to poor survival rates, symptom palliation and promotion of health-related quality of life (HRQoL) are primary outcomes for lung cancer patients. Given the established relationship between smoking and lung cancer, patients who have smoked may feel stigmatised or guilty after diagnosis, and more pessimistic about their illness and likely outcomes. This may have adverse implications for HRQoL. OBJECTIVES: We explored HRQoL and support experiences among newly diagnosed patients with advanced lung cancer. DESIGN: Semistructured interviews were conducted with nine patients and analysed using interpretative phenomenological analysis. RESULTS: Patients described the physical, emotional and social impact of disease on HRQoL. Fear of compromising their immune system and adjusting to new relationship roles had a wide-ranging effect on patients' HRQoL. Patients acknowledged links between lung cancer and smoking but some continued to smoke. They were sensitive to the opinions of medical staff about smoking especially those who continued to smoke or recently quit. CONCLUSIONS: We conclude that staff should give clearer advice about the adverse implications of continued smoking. We discuss the potential value of diagnosis as a teachable moment for promoting smoking cessation among patients and family members.

RESUMEN

Biochemical and cytochemical studies have revealed that abnormal processing of low-density-lipoprotein (LDL) cholesterol can be reversed in mutant Niemann-Pick C (NP-C) fibroblasts when 2% dimethyl sulfoxide (DMSO) is added to the culture medium. Both the excessive lysosomal accumulation of LDL cholesterol and the delayed induction of cellular homeostatic responses associated with the uptake of LDL by the mutant cells were substantially reversed by DMSO. DMSO appears to accelerate the intracellular mobilization of LDL-derived cholesterol through effects that may reflect enhanced membrane permeability or cholesterol solubilization.

RESUMEN

Seven patients with Fabry's disease and severe pain received carbamazepine (CMZ). Five of 7 patients had moderate to complete relief based upon self-assessment of pain levels. Preexisting autonomic dysfunction was exacerbated by CMZ in 2. Complications encountered were ileus, urinary retention, and gastrointestinal disturbance. Although CMZ was useful in treatment of pain, caution should be employed in this disease.

RESUMEN

We describe the unique clinical and histopathologic features of a child with biochemical and immunocytochemical features of Niemann-Pick disease type C (NPC). Clinically, she was found to have multiple xanthomas of the upper aerodigestive tract with dysphagia and expressive language delay, splenomegaly, bony infarcts, and type IIb hyperlipidemia. Neurologic examination was otherwise normal. Microscopy revealed foam cells in her bone marrow, liver, tongue, tonsils, glottis, and in normal-appearing peritonsillar mucosa. Lipid analysis of a liver biopsy specimen showed a small increase in phospholipids, a twofold increase in sphingomyelin, a fivefold increase in cholesterol, and a marked (25-fold) increase in bis(monoacylglycerol) phosphate. Lysosomal acid hydrolase activities in cultured skin fibroblasts were nondiagnostic. Biochemical and immunocytochemical studies of cultured fibroblasts demonstrated lysosomal accumulation of unesterified LDL-derived cholesterol as well as delayed induction of homeostatic responses to endogenous cholesterol consistent with a diagnosis of NPC. Based upon these observations, we speculate that this patient could have a new phenotypic expression of NPC or represents a new cholesterol lipidosis biochemically resembling NPC. The chance occurrence of two separate lipid disorders seems less likely.

RESUMEN

A sensitive sandwich immunoassay for human chorionic gonadotropin (hCG) was developed with biotin-mediated filtration capture and silicon sensor detection. A high density of biotin on the membrane assured efficient capture of complexes containing streptavidin and analyte. Capture efficiency was not affected over a wide range of filtration flow rates or biotin concentrations. The assay utilized the pH sensing ability of the light addressable potentiometric sensor (LAPS) for the detection of urease-antibody conjugates. A LAPS reader was constructed which allowed the enzyme conjugate to be detected in approximately 1 microliter volumes. Effects from variations in detection volume were studied. 10 pg of hCG could be detected in an assay time of 20 min with four standard deviations separation from background. Comparison to a commercial RIA was made.

RESUMEN

Injection ports are commonly used to maintain permanent vascular access in patients with malignant disease. The injection ports allow blood sampling as well as infusion or injection of chemotherapeutic agents directly into the circulation. The access catheters are usually placed in the subclavian vein with the injection port being implanted in the intraclavicular area. These injection ports are entirely self-contained underneath the skin and may have been placed in an area which subsequently requires radiation treatment. A comprehensive study of the perturbation effects of the injection ports when placed in the path of the beam was carried out. All dose measurements were performed using stainless steel and titanium injection ports. The radiation beams were 6 MV and 10 MV X rays and 6, 9, 12, 15, and 18 MeV electrons. The data indicate that the presence of injection ports significantly alters the radiation dose and dose uniformity. For example, the dose underlying a stainless steel port is reduced by 47% when 18 MeV electrons are used. This paper presents the dosimetric data, discusses the clinical significance of the results, and provides recommendations for design modifications of the ports.

RESUMEN

The abdominal cavities of 50 patients were explored in a specially constructed intraoperative radiotherapy operating amphitheater at the Medical College of Ohio. Twenty-six patients were treated with intraoperative and postoperative precision high dose external beam therapy, 12 with intraoperative irradiation but no external beam therapy, and 12 with palliative surgery alone. All but two patients completed the postoperative external beam radiation therapy as initially prescribed. The median survival time for patients treated with palliative surgery alone was 4 months, and that for patients treated with intraoperative radiotherapy without external beam therapy was 3.5 months. Patients undergoing intraoperative irradiation and external beam radiation therapy had a median survival time of 10.5 months. Four patients died within 30 days of surgery and two patients died of gastrointestinal hemorrhage 5 months posttreatment.

RESUMEN

Interstitial hyperthermia (44.0 +/- 0.5 degrees C for 40 minutes) was delivered to the livers of 16 dogs to determine acute effects of treatment on blood chemistry, histology, and cellular appearance of normal liver. SGOT in treated animals peaked immediately at 300 +/- 21 U/L (within 2 hrs) and returned to control value within 7 days. LDH levels peaked at 1 day post-treatment and again at 2 weeks (300 +/- 16 U/L and 340 +/- 25 U/L respectively) and returned to pre-treatment values by week 4. SGPT remained elevated for 6 to 7 days following hyperthermia, but returned to control value at 2 weeks. There was also a rise in alkaline phosphatase (200 +/- 14 U/L 1 day post-treatment), which returned to a pre-treatment level by week 3. Changes in serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, lactate dehydrogenase, and alkaline phosphatase were attributed to both liver parenchymal damage induced by hyperthermia and to surgery. Other deviations in the blood chemistries and hematological parameters measured were ascribed to the stress response from surgical intervention, or to the resultant hemodilution from fluids during surgery. Microscopic examination upon necropsy, performed 4 weeks post-operatively, displayed limited fibrosis with some alteration of liver architecture, generalized sinusoidal dilation and red blood cells in the space of Disse. Cellular ultrastructure changes showed an increase of myelin figures, but mitochondria and other cellular organelles remained essentially normal. Localized tissue inflammation and some loss of function occurred in response to localized hyperthermia for this volume of tissue at therapeutic temperatures. This study showed that the technique was feasible and confirmed that the parenchymal damage caused by interstitial hyperthermia did not produce the severe loss of function that might have been expected.

RESUMEN

Twenty-five patients with a diagnosis of unresectable adenocarcinoma of the pancreas were explored in the Clement O. Miniger (COMROC) IOEBT operating amphitheater at the Medical College of Ohio. Seventeen were treated with IOEBT (20-30 Gy, 15 or 18 meV electrons) PHD external beam radiation therapy (40-60 Gy, 1.8 Gy per fraction) plus appropriate operative biliary and gastrointestinal bypass procedures. No intraoperative complications were observed. Two patients died of causes that may have been treatment-related. Two patients developed abdominocutaneous fistulae. Pain was ameliorated in eleven of twelve patients. Jaundice was relieved in all patients. Four of ten patients with weight loss showed a reversal of that trend. Patient survival was not significantly different from that of patients treated with high-dose precision therapy alone.

RESUMEN

PURPOSE: A retrospective analysis to determine differences in survival of patients with pancreatic adenocarcinoma treated by radical surgery with and without adjuvant radiation therapy. METHODS AND MATERIALS: Between 1980 and 1995, 249 patients with pancreatic tumors were identified at the Medical College of Ohio. Forty-four of these patients underwent radical surgical procedures with curative intent. These patients were divided into four groups according to treatment: surgery alone (n = 14), surgery plus intraoperative radiation therapy (IORT) (n = 6), surgery plus external beam radiation therapy (EBRT) (n = 14), or surgery plus both IORT and EBRT (n = 10). Outcome and survival were analyzed among the four groups. RESULTS: The median survival time of patients treated with radical surgery alone was 6.5 months. The median survival time for the surgery plus IORT group was 9 months; however, 33.3% (two of six) of these patients survived longer than 5 years. This survival pattern was borderline significantly better than that for the surgery alone group (p = 0.0765). The surgery plus EBRT and the surgery plus IORT and EBRT groups had median survival times of 14.5 and 17.5 months, respectively. These were significantly better than that of the surgery alone group (p = 0.0004 and p = 0.0002, respectively). The addition of radiation therapy did not affect the treatment complication rate. CONCLUSION: The survival of patients who were treated with radical surgery alone was significantly poorer than that of patients who received adjuvant radiation therapy. These results are consistent with other studies in the literature. Patients treated with all three modalities (surgery, IORT, and EBRT) displayed the best median survival time.

RESUMEN

We report the clinical, light-microscopic, and ultrastructural features of a case of multifocal verruciform xanthoma in the upper aerodigestive tract of a child with a systemic lipid disorder. Lipid storage cells were found in liver, bone marrow, and as a component of verruciform xanthomas. To our knowledge this represents the first case of verruciform xanthoma reported in (a) a child, (b) as a multifocal lesion in the upper aerodigestive tract, (c) associated with a systemic lipid disorder, and (d) with ultrastructural evidence of lipid accumulation within endothelial cells. Although this patient presented with lesions involving the tongue and larnyx, subsequently lesions were found in the bone marrow and liver. Two months later more lesions were discovered on the epiglottis, posteior tongue, right glottis, and in grossly normal peritonsillar mucosa. Six months later a new oral lesion developed. Based upon these observations, we speculate that the pathogenesis of verruciform xanthoma involves accumulation of excess lipid in subepithelial sites which is scavenged by macrophages. Lipid-laden macrophages release epithelial growth factors that lead to epithelial hyperplasia. Depending on the degree of epithelial hyperplasia, the gross appearance of verruciform xanthomas may be flat, sessile, papillary, or verrucous.

RESUMEN

We evaluated nine patients with colorectal cancer and six control patients in a postabsorptive state in an attempt to define the effect of cancer on glucose turnover, oxidation, recycling, and resting metabolic expenditures (RME). The glucose kinetics were determined using a double-labeled [U-14C] glucose and [6-3H] glucose, and energy expenditures were measured by indirect calorimetry. In addition, we also measured the same parameters in the cancer patient group on a total parenteral nutrition (TPN)-glucose system on the fourth day before and on the fifth day after removal of tumor. In the postabsorptive state, glucose turnover and oxidation rates were similar in the cancer and control group; however, the mean glucose pool size of the cancer group was 47% larger than the control group and was statistically significant (P = .05). Glucose recycling was also two times the control group and was statistically significant (P = .05). The recycling of glucose, both preoperatively and postoperatively, continued in the face of infused glucose; however, the rate was suppressed compared with the fasting cancer group. Postabsorptive RME of the cancer group did not differ from those predicted by the Harris-Benedict equation. Following a 4-day infusion of TPN-glucose that supplied a mean of two times the patients' energy needs, the preoperative cancer group showed a mean increase in RME of 25.6% and a 31.58% increase on the fifth postoperative day of TPN-glucose, presumably due to increased lipogenesis and to a much lesser extent from the increased protein synthesis (4 g positive N balance).(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

BACKGROUND: Vascular access-related complications are an important cause of morbidity, and they account for 14% to 17% of dialysis patients' hospitalizations with an annual cost in the United States of approximately $1 billion. Previous studies have related the major predisposing factor of thrombotic complications to stenosis of the graft anastomosis. Several recent reports suggest that antiphospholipid antibodies may cause frequent thrombotic complications. The broad spectrum of diseases that cause hypercoagulable states has not been correlated with frequent PTFE graft thrombosis. STUDY DESIGN: A retrospective case series study was performed to determine the frequency of hypercoagulable states in dialysis patients who had repeated thrombotic complications of their PTFE grafts. Between May 1996 and June 1998, 91 operations were performed on 34 patients with end-stage renal disease. All arteriovenous fistulas were created with PTFE grafts and placed by a single surgeon. All patients were evaluated at operation for anastomotic stenosis, and the majority of patients were studied for hypercoagulable states. Patients with a documented hypercoagulable state were considered for warfarin therapy. RESULTS: Twenty-two individuals (64.7%) developed 67 thrombotic complications. Twelve of the 14 patients tested (85.7%) were shown to have hypercoagulable states of various causes and degrees. Thirteen patients developed multiple thrombotic complications, 11 (81.8%) were tested and proved to be hypercoagulable. Thirty-eight of the thrombotic complications had nonanatomic causes and 28 (41.8%) had hypercoagulability as the only determinable cause. Ten of the 12 hypercoagulable patients (83.3%) were relegated to intermediate to high-intensity warfarin therapy to reduce the incidence of thrombotic events. Hypercoagulable patients not receiving warfarin had a thrombosis rate of 4.0 events per year; patients on warfarin had a rate of 1.2 events per year. Twenty-three thrombotic events occurred in the anticoagulated group all with an International Normalized Ratio (INR) less than 2.7. This incidence of vascular access thrombosis may be prevented when patients are maintained at an optimal INR of 2.7-3.0. CONCLUSIONS: Hypercoagulability has been a major etiologic factor in PTFE graft thrombosis. Hypercoagulable states are often found in patients with multiple graft thromboses and in patients with nonanatomic causes for thrombosis. Antiphospholipid antibodies are prevalent in the patients with PTFE graft thrombosis, as well as abnormalities in the Protein-C, Protein-S, and Antithrombin III systems. PTFE graft thrombosis has been a frequent cause of morbidity in patients on hemodialysis, and diagnostic evaluation should include a hypercoagulability profile. Based on our data, warfarin therapy should be instituted when hypercoagulable states are found, unless otherwise contraindicated, and INR maintained at 2.7-3.0 to decrease morbidity and frequency of graft thrombosis.

RESUMEN

We polled general surgery residency program directors to determine whether the evaluation system used by a medical school--pass/fail versus competitive grading--has an effect on a student's ability to compete for a residency position in general surgery. A vast majority (89%) of respondents preferred to review medical student transcripts that use grades rather than pass/fail evaluations. In addition, 83% would prefer to evaluate their own students with a grading system rather than a pass/fail mark. Eighty-one percent of program directors believed that the medical student's ability to compete for a residency position was adversely influenced by the pass/fail method of evaluation. Since program directors appear to be biased in favor of an evaluation system that provides them with more objective data, we conclude that the use of the pass/fail grading system puts the medical student at a disadvantage in competing for general surgery residency positions.

RESUMEN

BACKGROUND: The purpose of this study was to investigate the validity of the Objective Structured Clinical Examination (OSCE) as an evaluation technique by comparing medical student performance on the OSCE with traditional forms of evaluation. SUBJECTS AND METHODS: We analyzed the performance of 129 third-year medical students in the 1997-1998 academic year on clinical evaluations, oral examinations, and NBME subject examinations, and on OSCE, which was not included in the final grade. RESULTS: The OSCE showed high correlation with the final grades received for the clerkship. Seventy-one percent of students receiving High Pass or Honors had high OSCE scores whereas 67% of students with low OSCE scores received poor or Defer grades. Pearson product-moment correlations demonstrated significant bivariate correlations with the other test parameters. CONCLUSIONS: This study demonstrates that the OSCE is similar to the traditional methods in evaluating general ability and is also able to evaluate clinical ability in a standardized manner.
