Short-term outcomes of a program developed to inculcate research essentials in undergraduate medical students

Background:

Participation in research during undergraduate studies may increase students’ interest in research and inculcate research essentials in them.

Aims:

The purpose of this study was to evaluate the effectiveness of the mentored student project (MSP) program.

Settings and Design:

In the MSP program, students in groups (n = 3 to 5) undertook a research project, wrote a scholarly report, and presented the work as a poster presentation with the help of a faculty mentor. To begin with, the logic model of the program was developed to identify short-term outcomes of the program on students, mentors, and the institution. A quasi-experimental design was used to measure the outcomes.

Materials and Methods:

A mixed method evaluation was done using a newly-developed questionnaire to assess the impact of the MSP on students’ attitude, a multiple-choice question (MCQs) test to find out the impact on students’ knowledge and grading of students’ project reports and posters along with a survey to check the impact on skills. Students’ satisfaction regarding the program and mentors’ perceptions were collected using questionnaires. Evidence for validity was collected for all the instruments used for the evaluation.

Statistical Analysis:

Non-parametric tests were used to analyze data. Based on the scores, project reports and posters were graded into A (>70% marks), B (60-69% marks), and C (<59% marks) categories. The number of MSPs that resulted in publications, conference presentation and departmental collaborations were taken as impact on the institution.

Results:

Students’ response rate was 91.5%. The students’ attitudes regarding research changed positively (P = 0.036) and score in the MCQ test improved (P < 0.001) after undertaking MSP. Majority of project reports and posters were of grade A category. The majority of the items related to skills gained and satisfaction had a median score of 4. The MSPs resulted in inter-departmental and inter-institutional collaborations, 14 publications and 15 conference presentations. An area for improvement noted was to have the MSP implemented in the curriculum without increasing students’ overall workload and stress.

Conclusion:

The study identified strengths and weaknesses of the MSP program. Our model of undergraduate research project may be incorporated in undergraduate medical programs to foster positive attitude and knowledge base about scientific research and to instil research skills among students.KEY WORDS: Attitude, knowledge, mentored, outcome, research, skills, student     

Circulatory and respiratory effects of aspiration and reinfusion of ascites in cirrhosis. Apropos of 14 ascitic attacks treated by this method]

Aspiration and replacement of ascites in 14 patients with cirrhosis was carried out using a Rhodiascit (Rh?ne-Poulenc) apparatus. Hemodynamic studies were used to evaluate the effects of this therapy on circulatory and respiratory parameters. Results showed that the hemodynamic tolerance of the treatment, which produces a slow increase in blood volume, was excellent as there was an increase in the cardiac index without raising the pressure under which replacement was made. Futhermore, no adverse effects on blood respiratory functions were noted in these patients who had blood hypoxia before treatment, but the removal of ascitic fluid produced no improvement in arterial gasometric parameters which is contrary to what one would expect.     

Successful treatment of Fusarium keratitis with cornea transplantation and topical and systemic voriconazole

A case of invasive Fusarium keratitis in a previously healthy male patient was treated successfully with cornea transplantation and systemic and topical voriconazole after treatment failure with topical amphotericin B and systemic itraconazole. Topical voriconazole was well tolerated, and, in conjunction with the oral administration, it resulted in a high level of the drug in the anterior chamber of the eye (which was 160% of the plasma drug level).     

Acute pyelonephritis with renal abscesses and acute renal failure after salmonella infection

Urinary tract infections, renal abscess formation and acute renal failure (ARF) after salmonella infection are rarely reported in children. We present a previously healthy teenager who developed ARF with renal abscess formation after salmonella infection, in whom we believe that acute salmonella pyelonephritis was the main causative factor for ARF and not dehydration, shock or rhabdomyolysis, which have already been described in the literature. With prolonged antibiotic treatment and adequate hydration, the boy’s condition improved, but chronic kidney disease was unfortunately inevitable. Conclusion: Salmonella pyelonephritis has, according to our knowledge, not yet been described to be the main causative factor of ARF in previously healthy children, as was the case in our patient. Long‐term antibiotic treatment of at least 6 weeks is probably a must in such patients, even though chronic kidney disease could not have been prevented.     

Rapid MR imaging with suspended respiration: clinical application in the liver

The authors demonstrate that it is possible to obtain highly T1-weighted images of the abdomen using a suspended respiration partial saturation (SRPS) method in a breath-holding interval. T2*-weighted images, which reflect tissue T2 as well as variations in the static magnetic field, can also be rapidly obtained. The authors studied five healthy subjects and 19 patients with a variety of liver abnormalities, including benign and malignant hepatic neoplasms, fatty liver infiltration, ascites, and hematoma. On T1-weighted multisection acquisitions, the entire liver can be screened for mass lesions in a single 20-second breath-holding interval. Phase-contrast SRPS images are sensitive to fatty infiltration of the liver. SRPS images are more sensitive to variations in magnetic susceptibility than spin-echo images are, which has been proved to be of value in the detection of hemorrhage. With continued pulse sequence development and clinical study, this method has the potential to become the method of choice for evaluation of the upper abdomen.     

Orthotopic cardiac transplantation: evaluation with CT

As cardiac transplantation has become widely available, computed tomography (CT) of the chest has played a useful role in the examination of patients after heart transplantation. To determine anatomic features related to the procedure, the authors evaluated 59 scans in 46 patients who had undergone orthotopic cardiac transplantation. Aortic anastomosis (seen in 98% of scans) and altered spacing between the great vessels (83%) proved to be the most common and most reliable findings. Other features including atrial anastomosis, high main pulmonary artery segment, remnant superior vena cava, and cardiac reorientation were also seen. Accurate interpretation of adenopathy, mediastinal abscess, and pericardial effusion will be enhanced in these patients through a better understanding of the cardiovascular-pericardial complex, which is afforded by CT.
