Background:

 The learning problems in the basic sciences field of study can cause further learning problems at higher levels and even in the future career. This study aims to evaluate the educational performance of medical students in basic sciences at Semnan University of Medical Sciences (SUMS) during a ten-year academic period.

Methods:

 This is an analytical study with a cross-sectional design that was conducted in 2021. All students of SUMS, who participated in the basic science comprehensive exam from 2011 to 2020, were selected by a census method (n=316). Their information was collected using a a researcher-made questionnaire and analyzed by descriptive statistics and Paired t-test in SPSS software, version 16.

Results:

 Of 316 students, 62.3% were males. Most of them had exams in September 2017 (n=32), while the least had exams in September 2016 (n=3). The best status was related to those had exams in March 2017 (Average grade: 145), and the worst was related to those in September 2017 (Average grade: 100). Overall, the average grade of students in the March exam (128.8) was better than the average grade of September exam (114.2). The highest grades were observed in the courses of pathology, bacteriology, physiology, and immunology, while the lowest grades were observed in the courses of medical physics, embryology, and public health. Overall, there was no significant relationship between the average grades of the groups March and September (P=0.073). The basic science comprehensive exam grades had a significant relationship with grade point average (P=0.033) and gender (P=0.42).

Conclusion :

The educational performance of students in basic sciences at SUMS has not changed significantly in ten years. Long-term educational evaluations of students are recommended to university managers and officials for proper planning.

Educational underachievement is a major problem for every educational system, with not only personal issues, but also social impacts, leading to disruptions and waste of training costs. The present study was conducted to determine the influencing factors of educational underachievement among talented students.

This descriptive cross-sectional study was performed in 2012-13. The population consisted of all the 53 talented students with educational underachievement in Semnan University of Medical Sciences. A researcher-made questionnaire on educational underachievement was used to collect data, with four fields, student-related, universities and educational environment, Family and Community, and instructors. Validity and reliability of the questionnaire was calculated with content validity and Cronbach's alpha (0.83). The data was analyzed using descriptive statistics and t-test.

The most important factors affecting academic performance were lack motivation, pleasure from studying, emotional problems due to incompatibility with the environment, low quality of teaching, non-standardized exam questions, lack of Incentives, Lack of attention to talented students from authorities and lack of proper planning education. In the analysis, the employment of academic failure (P=0.036), living situation (P=0.018), socioeconomic status (P=0.026), disease (P=0.009), parental education (P=0.043), type of Planning (P=0.010), the presence in the classroom (P=0.012) and the current interest in the field (P=0.021), was found to have a significant correlation.

Various factors affect talented students’ educational underachievement.Exploring these factors and providing solutions to educational administrators, seem necessary and are recommended to researchers.

Hip fracture is very common orthopaedic fracture in elderly. The present study investigates the outcome after surgical treatment. The hip fractures of over 65-year old patients that had undergone surgery in a 5-year period were retrospectively studied in a hospital in Semnan، Iran. The information of 259 patients (120 male، 139 women) were collected including demographic data، medical history، history of surgery (type of anesthesia، technique of surgery)، length of hospitalization before and after surgery، and death in hospital. From all the operated cases، 174 (67. 2%) received spinal، 68% (26. 3)، epidural and 17% (6. 6) general anesthesia. 185 pateints (71. 4%) had no complication and 74% (28. 6) had at least one complication. 12 patients (6. 4) died while in hospital. 56 cases (21. 6%) were walking with no problem; 32 (12. 4%) required walking and 9 patients (3. 5%) were not able to walk. Complications after surgery for hip fracture are relatively high. To recover faster and reduce more serious complications، it is recommended to change the strategies on how to care for the elderly during and after surgery.

Gastrointestinal motility disorders are considered one of the most common digestive problems in the intensive care units that mainly appear as decreased gastrointestinal motility and constipation. The current study is to evaluate theincidence of constipation in the intensive care unit and effect of medications to treat it. 31 patients were studied. Inclusion criteria were age≥ 18 years، hospitalization in the intensive care unit for more than three days، receiving enteral nutrition and non-malignant gastro intestinal or stomach surgery. Evaluation criteria forconstipation was lack of gastrointestinal excretion for three consecutive days. Constipation occurred in 61. 3% (n=19) of the patients. There was no difference between constipated and not constipated in terms of sex، age، Acute Physiology and Chronic Health Evaluation II، mechanical ventilation، sedation and opiate use. Incidence of constipation with increased length of stay in the intensive care unit were significantlycorrelated (11. 5±5 days vs. 6. 5±5 days). There was no difference between patient using laxative and other patients in the incidence of constipation. Despite medical treatment، constipation in ICU، had a high incidence that increased duration of hospitalization. Several factors influencing the incidence of constipation and lack ofatreatment protocol from doctors and nurses is the most important reason for the high prevalence of constipation.
