Medical students' perceptions of their learning environment during clinical years at Chitwan Medical College in Nepal.

BACKGROUND: The educational environment of an institution affects learning and has a significant role in determining students' academic achievement. The objective of the study was to determine the undergraduate medical students' perception about educational environment in clinical years of study utilizing Dundee Ready Education Environment Measure (DREEM) questionnaire. METHODS: A descriptive cross-sectional questionnaire-based study was conducted among fourth and fifth-year medical students toward the end of their 2016 academic year in Chitwan Medical College, Bharatpur, Nepal. The 50-item DREEM questionnaire was used to collect the data. The items were scored based on a 5-point Likert scale. The data were analyzed using SPSS version 20. Scores obtained were expressed as mean±SD. RESULTS: The mean total DREEM score was 122/200. The mean score for Students' Perceptions of Learning, Students' Perceptions of Teachers, Students' Academic Self-Perceptions, Students' Perceptions of Atmosphere, and Students' Social Self-Perceptions were 29.8/48, 25.9/44, 20.3/32, 28.6/48, and 17.27/28, respectively. This shows the environment for learning was satisfactory. There were nine problem areas with a mean score of ≤2. There was no significant difference observed in educational environment subscales scores according to enrollment year, gender, or funding source for education. CONCLUSION: The overall student's perception of the educational environment was satisfactory. Nevertheless, the study revealed some problematic areas in the learning environment which require remedial measures to make the environment more conducive for learning to satisfy the students and achieve a far better outcome.

Attitude and perception of undergraduate medical students toward the problem-based learning in Chitwan Medical College, Nepal.

BACKGROUND: Problem-based learning (PBL) was introduced into Basic Medical Sciences early in the 1980s at Tribhuvan University (TU), Nepal, followed by other universities where didactic lecture method was still followed as the main teaching strategy. Despite gaining its popularity worldwide as integrated teaching learning method, PBL is not given importance in Nepal. This study aimed to assess the attitude and perceptions of undergraduate medical students regarding learning outcomes of PBL and to know their views about role and qualities of effective tutors for its successful implementation. METHODS: This descriptive study was based on a self-administered questionnaire. The first part of the questionnaire measured students' perception and attitude toward benefits of PBL and the second part measured students' perception about role of PBL tutor. Bachelor of Medicine and Bachelor of Surgery (MBBS) first year (2014/2015 academic year) students at Chitwan Medical College, TU, were asked to express their opinions about the importance of learning outcomes by rating each statement on a five-point Likert scale and the responses were combined into three categorical variables: "agree" (strongly agree plus agree), "neutral", and "disagree" (strongly disagree plus disagree). Data were analyzed using SPSS version 21.0. RESULTS: Approximately 85.5% participants agreed that PBL is an interesting method of teaching learning. Most of them (86.7%) accepted that PBL is an interactive and a mutual learning method and improves self-directed learning (83.2%). Although 78% had recommended it better than lecture, many (54.2%) pointed it out as a time-consuming method. The participants were also highly rated (80.5%) to the statement - the tutor's role in enhancing the constructive active learning and maintaining good intra-personal behavior. CONCLUSION: Student's attitude toward PBL was positive. They highly appreciated the roles of a tutor as facilitators and motivators for proper activities in PBL session. PBL sessions were considered effective in improving students professional knowledge and refining problem-solving and self-directed learning skills along with enriching teamwork experience.

Nerve Conduction Study on Sural Nerve among Nepalese Tailors Using Mechanical Sewing Machine.

INTRODUCTION: The use of new technologies and innovations are out of access for people living in a developing country like Nepal. The mechanical sewing machine is still in existence at a large scale and dominant all over the country. Tailoring is one of the major occupations adopted by skilled people with lower socioeconomic status and education level. Sural nerves of both right and left legs are exposed to strenuous and chronic stress exerted by chronic paddling of mechanical sewing machine with legs. AIM: To evaluate the influence of chronic and strenuous paddling on right and left sural nerves. MATERIALS AND METHODS: The study recruited 30 healthy male tailors with median age {34(31-37.25)} years (study group), and, 30 healthy male volunteers with age {34(32-36.25)} years (control group). Anthropometric measurements (age, height, weight, BMI and length of both right and left legs) as well as cardio respiratory measurements [Systolic Blood Pressure (SBP), Dystolic Blood Pressure (DBP), Pules Rate (PR) and Respiratory Rate (RR)] were recorded for each subject. Standard nerve conduction techniques using constant measured distances were applied to evaluate sural nerve (sensory) in both legs of each individual. The differences in variables between the study and control groups were tested using Student's t-test for parametric variables and Mann-Whitney U test for nonparametric variables. A p-value of ≤ 0.05 was considered significant. RESULTS: Age, height, weight, body mass index and leg length were not significantly different between tailors and control groups. Cardio respiratory measurements (SBP, DBP, PR and RR) were also not significantly altered between both the groups. The sensory nerve conduction velocities (m/s) of the right {44.23(42.72-47.83) vs 50(46- 54)} and left sural nerves {45.97±5.86 vs 50.67±6.59} m/s were found significantly reduced in tailors in comparison to control group. Similarly amplitudes (µv) of right sural (20.75±5.42 vs 24.10±5.45) and left sural nerves {18.2(12.43-21.8) vs 32.0(26.5-35.25)} were significantly less in tailors in comparison to control group whereas, latencies (ms) of right sural {2.6(2.2-2.7) vs 2.0(2.0-2.250} and left sural nerve {2.4(2.07-2.72) vs 2.0(2.0-2.0)} were found significantly high in tailors as compared with control group. CONCLUSION: Operating mechanical sewing machine by paddling chronically and arduously could have attributed to abnormal nerve conduction study parameters due to vibration effect of the machine on right and left sural nerves. The results of present study follow the trend towards presymptomatic or asymptomatic neuropathy similar to subclinical neuropathy.

Vibration upshot of operating mechanical sewing machine: an insight into common peroneal nerve conduction study.

BACKGROUND: Most of the people associated with tailoring occupation in Nepal are still using mechanical sewing machine as an alternative of new technology for tailoring. Common peroneal nerves of both right and left legs are exposed to strenuous and chronic stress exerted by vibration and paddling of mechanical sewing machine. METHODS: The study included 30 healthy male tailors and 30 healthy male individuals. Anthropometric variables as well as cardio respiratory variables were determined for each subject. Standard Nerve Conduction Techniques using constant measured distances were applied to evaluate common peroneal nerve (motor) in both legs of each individual. Data were analyzed and compared between study and control groups using Man Whitney U test setting the significance level p ≤ 0.05. RESULTS: Anthropometric and cardio respiratory variables were not significantly altered between the study and control groups. The Compound muscle action potential (CMAP) latency of common peroneal nerves of both right [(11.29 ± 1.25 vs. 10.03 ± 1.37), P < 0.001] and left [(11.28 ± 1.38 vs. 10.05 ± 1.37), P < 0.01] legs was found to be significantly prolonged in study group as compared to control group. The Amp-CMAP of common peroneal nerves of both right [(4.57 ± 1.21 vs. 6.22 ± 1.72), P < 0.001] and left [(4.31 ± 1.55 vs. 6.25 ± 1.70), P < 0.001] legs was found significantly reduced in study group as compared to control group. Similarly, the motor nerve conduction velocity (MNCV) of common peroneal nerves of both right [(43.72 ± 3.25 vs. 47.49 ± 4.17), P < 0.001] and left [(42.51 ± 3.82 vs. 46.76 ± 4.51), P < 0.001] legs was also found to be significantly reduced in study group in comparison to control group. CONCLUSION: Operating mechanical sewing machine by paddling chronically and arduously could have attributed to abnormal nerve conduction study parameters due to vibration effect of the machine on right and left common peroneal nerves. The results of present study follow the trend towards presymptomatic or asymptomatic neuropathy similar to subclinical neuropathy.

Somatic neural alterations in non-diabetic obesity: a cross-sectional study.

BACKGROUND: Reports on alterations in somatic neural functions due to non-diabetic obesity, a major risk factor for diabetes, are few and still a matter of debate. Nevertheless, to our knowledge, reports lack any comments on the type of somatic nerve fibers affected in non-diabetic obesity. Therefore, this study aimed to find out the alteration in somatic neural functions in non-diabetic obese persons if any. METHODS: The study was conducted on 30 adult non-diabetic obese persons (mean age 32.07 ± 7.25 years) with BMI > 30 Kg/m2 (mean BMI 30.02 ± 2.89 Kg/m2) and 29 age- and sex-matched normal weight controls (mean age 30.48 ± 8.01 years) with BMI: 18-24Kg/m2 (mean BMI 21.87 ± 2.40 Kg/m2). Nerve conduction study (NCS) variables of median, tibial and sural nerves were assessed in each subject using standard protocol. The data were compared by Mann Whitney 'U' test. RESULTS: In comparison to normal weight persons, obese had lower compound muscle action potential (CMAP) amplitudes of right median [9.09(7.62-10.20) Vs 10.75(8.71-12.2) mV, p = 0.025] and bilateral tibial nerves [Right: 8.5(7.04-11.18) Vs 12.1(10.55-15) mV, p < 0.001 and left 9.08(6.58-11.65) Vs 13.05(10.2-15.6) mV, p = 0.002]. Furthermore, obese persons had prolonged CMAP durations of right and left median [10.5(9.62-12) Vs 10(8.4-10.3) ms, p = 0.02 and 10.85(10-11.88) Vs 10(9-10.57) ms, p = 0.019] and right tibial [10(9-11) 8.5(7.92-10) ms, p = 0.032] nerves. Sensory NCS (sural nerve) also showed diminished sensory nerve action potential (SNAP) amplitude [16(12.08-18.21) vs 22.8(18.3-31.08) µV, p < 0.001] and prolonged duration. However, onset latencies and conduction velocities for all nerves were comparable between the groups. CONCLUSION: This study documents subclinical peripheral nerve damage in non-diabetic obese with abnormal NCS parameters; shorter amplitudes and prolonged CMAP and SNAP durations. The reduced amplitudes of mixed and sensory nerves might be due to decreased axonal number stimulation or actual decrease in number of axonal fibers, or defect at NMJ in non-diabetic obese. Prolonged durations but normal onset latencies and conduction velocities strongly suggest involvement of slow conducting fibers.

Facebook use and its effects on the life of health science students in a private medical college of Nepal.

BACKGROUND: Facebook, a popular social networking site, has been used by people of different ages and professions for various purposes. Its use in the field of medical education is increasing dramatically. At the same time, the pros and cons of facebook use among the health science students has attracted the attention of educators. The data regarding its use and the effect on the life of Nepalese health science students has not yet been documented. Therefore, this study is carried out to evaluate the effect of facebook use on social interactions, behaviour, academics, and the health of students in a medical college of Nepal. RESULTS: A cross-sectional descriptive study conducted among medical, dental, nursing and allied health science students using self-administered questionnaire. The study showed that 98.2 % of participants were facebook users. Among 452 respondents, 224 and 228 were male and female respectively, with a mean age of 20.2 ± 1.2 years. The main reason for using facebook was to remain in contact with family and friend (32 %), while its use for the academic purpose was only 5 %. However, 80.8 % of students acknowledged ease in acquiring academic materials from others, through facebook. One-fourth of the students acknowledged that they are using facebook late at night on a regular basis, while surprisingly 4.2 % of the students admitted accessing facebook during the classroom lectures. Almost two-third of the users, further admitted that facebook has had a negative impact on their studies. Burning eyes (21 %), disturbed sleep (19 %), and headache (16 %) were the most common adverse health effects reported by the facebook users. Many students (71.4 %) tried and most of them (68.7 %) succeeded, in reducing time spent on facebook, to allow for increased time devoted to their studies. CONCLUSION: The widespread use of facebook among the health science students, was found to have both positive and negative effects on their academics, social life, and health.

Learning approach among health sciences students in a medical college in Nepal: a cross-sectional study.

BACKGROUND: Many factors shape the quality of learning. The intrinsically motivated students adopt a deep approach to learning, while students who fear failure in assessments adopt a surface approach to learning. In the area of health science education in Nepal, there is still a lack of studies on learning approach that can be used to transform the students to become better learners and improve the effectiveness of teaching. Therefore, we aimed to explore the learning approaches among medical, dental, and nursing students of Chitwan Medical College, Nepal using Biggs's Revised Two-Factor Study Process Questionnaire (R-SPQ-2F) after testing its reliability. METHODS: R-SPQ-2F containing 20 items represented two main scales of learning approaches, deep and surface, with four subscales: deep motive, deep strategy, surface motive, and surface strategy. Each subscale had five items and each item was rated on a 5-point Likert scale. The data were analyzed using Student's t-test and analysis of variance. Reliability of the administered questionnaire was checked using Cronbach's alpha. RESULTS: The Cronbach's alpha value (0.6) for 20 items of R-SPQ-2F was found to be acceptable for its use. The participants predominantly had a deep approach to learning regardless of their age and sex (deep: 32.62±6.33 versus surface: 25.14±6.81, P<0.001). The level of deep approach among medical students (33.26±6.40) was significantly higher than among dental (31.71±6.51) and nursing (31.36±4.72) students. In comparison to first-year students, deep approach among second-year medical (34.63±6.51 to 31.73±5.93; P<0.001) and dental (33.47±6.73 to 29.09±5.62; P=0.002) students was found to be significantly decreased. On the other hand, surface approach significantly increased (25.55±8.19 to 29.34±6.25; P=0.023) among second-year dental students compared to first-year dental students. CONCLUSION: Medical students were found to adopt a deeper approach to learning than dental and nursing students. However, irrespective of disciplines and personal characteristics of participants, the primarily deep learning approach was found to be shifting progressively toward a surface approach after completion of an academic year, which should be avoided.

Turmeric (curcumin) remedies gastroprotective action.

The purpose of this review is to summarize the pertinent literature published in the present era regarding the antiulcerogenic property of curcumin against the pathological changes in response to ulcer effectors (Helicobacter pylori infection, chronic ingestion of non-steroidal anti-inflammatory drugs, and exogenous substances). The gastrointestinal problems caused by different etiologies was observed to be associated with the alterations of various physiologic parameters such as reactive oxygen species, nitric oxide synthase, lipid peroxidation, and secretion of excessive gastric acid. Gastrointestinal ulcer results probably due to imbalance between the aggressive and the defensive factors. In 80% of the cases, gastric ulcer is caused primarily due to the use of non-steroidal anti-inflammatory category of drug, 10% by H. pylori, and about 8-10% by the intake of very spicy and fast food. Although a number of antiulcer drugs and cytoprotectants are available, all these drugs have side effects and limitations. In the recent years a widespread search has been launched to identify new antiulcer drugs from synthetic and natural resources. An Indian dietary derivative (curcumin), a yellow pigment found in the rhizome of Curcuma longa, has been widely used for the treatment of several diseases. Epidemiologically, it was suggested that curcumin might reduce the risk of inflammatory disorders, such as cancer and ulcer. These biological effects are attributed to its anti-inflammatory and antioxidant activities. It can, therefore, be reported from the literature that curcumin PRevents gastrointestinal-induced ulcer and can be recommended as a novel drug for ulcer treatment.

The treatment of visceral leishmaniasis: safety and efficacy.

Visceral leishmaniasis is the disease of poor; however availability of only expensive treatment of this disease impinges the socioeconomic condition of those affected. If untreated, almost all cases of visceral leishmaniasis are fatal. The demonstration of the leishmania donovani bodies from the tissue aspirates or serological tests confirms the diagnosis of the disease. Pentavalent antimony, amphotericin B, paromomycin, diamine pentamidine, miltefosine, sitamaquine and some new combinations are integrated in the limited therapeutic armoury for treatment of visceral leishmaniasis. The recommended first and second line therapy in the Indian sub-continent is miltefosine and amphotericin B respectively.Pentavalent antimonial, preceding first line therapy, has been replaced by miltefosine due to former increasing failure rate and toxicity.The problem of drug resistance, some of the serious drug toxicities along with high-priced drugs extends challenges equally to pharmaceutical companies and medical practitioners. More research on adverse drug events for the existing drugs and efforts to develop safer and effective drugs to counter resistance outbreaks for the successful management of visceral leishmaniasis are needed.
