ABSTRACT

INTRODUCTION: 1000 First Days of Life (1000FDL) training program is carried out for 2 years from the 3rd to 6th semester; in this program, students are asked to accompany pregnant women until their children are 2 years old. This study aimed to analyse undergraduate medical students’ communication skills and empathy levels and determine the association between communication skills and empathy after the training program.

METHODS: This is a cross-sectional study in which 176 undergraduate medical students in Hasanuddin University participated; they were enrolled in 1000FDL training program and selected using purposive sampling. Data were collected using Modified Arabic Version of the ABIM’s Patient Assessment (MAV-ABIM) and Jefferson Scale of Empathy – Student Version (JSE-S) questionnaires to assess their level of communication skills and empathy. In this study, demographic data were obtained using a semi-open-ended questionnaire. Data were analysed using descriptive statistics, Chi-Square, and Spearman tests.

RESULTS: Communication skill was very good (83.5%), good (15.9%), and inadequate (0.6%), while the empathy level was high (9.1%), medium (25%), and low (65.9%). There was no significant difference between the level of communication skills (p-value 0.168) and empathy (p=0.145) based on gender, but there was a significant difference between <12 or >12 times interaction with the empathy level (p<0.001). The association between the level of communication showed that the level of empathy was significant (p<0.001, r=0.399).

CONCLUSION: Undergraduate medical students had very good communication skills but low empathy levels. There was a positive association between communication skills and empathy level after the training program. The students’ empathy level can be improved by increasing the frequency of interaction with patients in experiential learning through training programs.

ABSTRACT

INTRODUCTION: Creating a supportive clinical learning environment (CLE) is one of the characteristics of an effective clinical instructor in nursing. Perhaps empowering novice clinical educators using mentorship method can reduce or resolve this problem. The aim of this study was to determine the impact of the mentorship program for novice clinical educators on the nursing students’ actual and preferred understanding of CLE.

METHODS: This quasi-experimental study on three groups was conducted as post-intervention with the participation of 139 undergraduate nursing students of Mashhad University of Medical Sciences. Sampling was done via stratified and multi-stage method. Students were placed in three groups: expert clinical educator (n=47), novice clinical educator (n=51), and mentorship (n=41). In the novice and expert clinical educator groups, training was conducted through the conventional method. In the mentorship group, a novice clinical educator (mentee) and an expert clinical educator (mentor) had a mentoring relationship for two weeks. The Chan (2001) CLE inventory was completed at the end of the first and second weeks of externship. Data were analyzed through SPSS v. 16 software using one-way ANOVA and paired t-tests.

RESULTS: The students of the three groups were homogeneous in terms of gender (p=0.101) and level of interest in the field (p=0.278). According to the result of the paired t-test, the difference in the mean score of the actual and preferred CLE at the end of the first week was statistically significant in the novice clinical educators (p=0.008) and the mentorship group (p=0.04); however, after the implementation of mentorship program (at the end of the second week), the difference was significant only in the novice educators group (p=0.001).

CONCLUSION: The implementation of the mentorship program for novice clinical educators (as with the expert educators group) could lead to a reduction in the mismatch between the actual and preferred views of students about the CLE. Thus, it is recommended that this method should be used under conditions of shortage of expert educators to create a supportive CLE.

ABSTRACT

INTRODUCTION: Gamification is the use of game design elements in non-game contexts. It is considered a student-centered instructional design to motivate student learning and academic behavior. In this study, the effects of gamification on learning statistics (hypothesis testing issue) and attitude toward statistics in comparison with the common e-learning approach were investigated. The students’ experience and critical elements of gamification on learning statistics were assessed, too.

METHODS: In a before and after trial, in a census manner, 64 health faculty students of Guilan University of Medical Sciences, Rasht, Iran, non-randomly were assigned to the intervention (n=42) and control (n=22) groups. Learning activities were gamified in the intervention group, while the control group received traditional problem-solving in the learning management system. Narrative, avatar, level, point, progress bar, scoreboard, challenge and feedback elements were used in the game experience. The implementation of gamification was applied based on Landers’ theory of gamified content. Valid and reliable Persian version of the Survey Attitude toward Statistics questionnaire measured the students’ attitude before and after the intervention. The EGameFlow questionnaire and a valid and reliable researcher-made exam measured the users’ experience of gamified content and learning hypothesis testing after the intervention. The independent samples T-test, analysis of covariance and the partial eta-squared effect size were calculated by SPSS software, version 26.

RESULTS: Compared to the control group, the intervention group had a more positive attitude toward learning difficulty (moderate partial eta-squared 0.099), value and cognitive competency (weak partial eta-squared=0.01 and 0.05). Learning between the two groups was not different (P=0.522). There was a significant correlation between learning and the students’ perceived experience with feedback (r=0.583, P<0.001), concentration (r=0.509, P=0.005), and challenge (r=0.421, P=0.023) of the gamified content.

CONCLUSION: It suggests using gamification on learning statistics while optimizing the design with more focus on the feedback, challenge and concentration elements.

ABSTRACT

BACKGROUND: Patients with colorectal cancer may need postoperative nursing to improve prognosis, and conventional nursing is not effective. Clinical research is needed to explore nursing methods that can more effectively improve postoperative conditions on colorectal cancer patients undergoing colostomy.

AIM: To explore the effect of internet multiple linkage mode-based extended care combined with in-hospital comfort care on colorectal cancer patients undergoing colostomy.

METHODS: Data from 187 patients with colostomy treated in our hospital from May 2019 to March 2022 were collected and divided into three groups, A (n = 62), B (n = 62) and C (n = 63), according to different intervention methods. Group A received internet multiple linkage mode-based extended care combined with in-hospital comfort care. Group B received internet multiple linkage mode-based extended care. Group C received usual care intervention. Complications were compared among the three groups. The stoma self-efficacy scale, Hamilton Anxiety Scale, Hamilton Depression Scale, Brief Fatigue Inventory and City of Hope-quality of Life-ostomy Questionnaire before and after intervention were compared among the three groups.

RESULTS: The complication rate of group A, B and C (16.13%, 20.97% and 60.32%, respectively) was significantly different (all P < 0.05). The incidence of complications in groups A and B was lower than that in group C, and there was no significant difference between groups A and B (P > 0.05). After intervention, the scores of ostomy care, social contact, diet choice, confidence in maintaining vitality, confidence in self-care of ostomy, confidence in sexual life, confidence in sexual satisfaction and confidence in physical labor in the three groups were all higher than before intervention, and the scores of groups A and B were higher than those of group C, with statistical significance (P < 0.05). The Hamilton Anxiety Scale and Hamilton Depression Scale scores of the three groups after intervention were lower than those before intervention. The scores of groups A and B were lower than those of group C, and the score of group A was lower than that of group B, all with statistical significance (all P < 0.05). There was a statistically significant difference in cancer-induced fatigue among the three groups (P < 0.05). After intervention, the scores of physical health, psychological health, social health and mental health of the three groups were lower than before the intervention. The scores of group A and B were lower than that of group C; and the score of group A was lower than that of group B, all with statistical significance (all P < 0.05).

CONCLUSION: Internet multiple linkage mode-based extended care combined with in-hospital comfort care can effectively improve self-efficacy, bad mood, cancer-related fatigue and life quality of colorectal cancer patients undergoing colostomy.

ABSTRACT

BACKGROUND: Computed tomography (CT) technology has been gradually used in the differentiation of small mesenchymal tumors of the stomach and intestines from smooth muscle tumours.

AIM: To explore the value of enhanced CT in the differentiation of small mesenchymal tumors of the stomach and intestines from smooth muscle tumours.

METHODS: Clinical data of patients with gastric mesenchymal or gastric smooth muscle tumours who were treated in our hospital from May 2018 to April 2023 were retrospectively analysed. Patients were divided into the gastric mesenchymal tumor group and the gastric smooth muscle tumor group respectively (n = 50 cases per group). Clinical data of 50 healthy volunteers who received physical examinations in our hospital during the same period were selected and included in the control group. Serum levels of carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), carbohydrate antigen 19-9 (CA19-9), CA-125 and cytokeratin 19 fragment antigen 21-1 were compared among the three groups. The value of CEA and CA19-9 in the identification of gastric mesenchymal tumours was analysed using the receiver operating characteristic (ROC) curve. The Kappa statistic was used to analyse the consistency of the combined CEA and CA19-9 test in identifying gastric mesenchymal tumours.

RESULTS: CEA levels varied among the three groups in the following order: The gastric mesenchymal tumour group > the control group > the gastric smooth muscle tumour group. CA19-9 levels varied among the three groups in the following order: The gastric mesenchymal group > the gastric smooth muscle group > the control group, the difference was statistically significant (P < 0.05). ROC analysis showed that the area under the curve of CEA and CA19-9 was 0. 879 and 0. 782, respectively.

CONCLUSION: Enhanced CT has shown value in differentiating small mesenchymal tumors of the stomach and intestines from smooth muscle tumors.

ABSTRACT

BACKGROUND: Ultrasound is a vital tool for the diagnosis and management of colorectal cancer (CRC). Contrast-enhanced ultrasound (CEUS) is a non-invasive, safe, and cost-effective method for evaluating tumour blood vessels, that play a crucial role in tumour growth and progression.

AIM: To explore CEUS’s role in the quantitative evaluation of CRC blood vessels and their correlation with angiogenesis markers and prognosis.

METHODS: This study prospectively enrolled 100 patients with CRC confirmed by histopathology. All patients received preoperative CEUS examinations. Quantitative parameters, such as peak intensity (PI), time to peak (TTP), and area under the curve (AUC), were derived from time-intensity curve (TIC) analysis. Tumour tissue samples were obtained during surgery and examined immunohistochemically to assess the expression of angiogenesis markers, including vascular endothelial growth factor (VEGF) and microvessel density (MVD). The correlation between CEUS parameters, angiogenesis markers, and clinicopathological features was evaluated using appropriate statistical tests.

RESULTS: Quantitative CEUS parameters (PI, TTP, and AUC) showed significant correlations with VEGF expression (P < 0.001) and MVD (P < 0.001), indicating a strong link between tumour blood vessels and angiogenesis. Increased PI, reduced TTP, and expanded AUC values were significantly related to higher tumour stage (P < 0.001), lymph node metastasis (P < 0.001), and distant metastasis (P < 0.001). Furthermore, these parameters were recognized as independent predictors of overall survival and disease-free survival in multivariate analysis (P < 0.001).

CONCLUSION: CEUS has a high potential in guiding treatment planning and predicting patient outcomes. However, more comprehensive, multicentre studies are required to validate the clinical utility of CEUS in CRC management.

ABSTRACT

BACKGROUND: Early postoperative inflammatory small bowel obstruction (EPISBO) is easy to be complicated after colorectal cancer surgery. Both intestinal obstruction catheter and meglumine can treat EPISBO.

AIM: To investigate the efficacy of an intestinal obstruction tube combined with meglumine diazo in treating EPISBO of colorectal cancer.

METHODS: Data from 60 patients with colorectal cancer and intestinal obstruction admitted to the Proctology Department of our hospital from April 2018 to May 2022 were collected and analyzed and divided into three cohorts according to different treatment regimens. Cohort A (n = 20) received a transnasal intestinal obstruction catheter with panumglumine, and cohort B (n = 20) received a transnasal intestinal obstruction catheter with liquid paraffin. Cohort C (n = 20) received oral treatment with meglumine. The clinical efficacy, first exhaust/defecation time, length of hospital stay, gastrointestinal decompression time, relief time of abdominal pain, and relief time of abdominal distension were compared among the three cohorts. The levels of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), monocyte chemotactic protein-1 (MCP-1), serum albumin, and transferrin were compared among the three cohorts before and after treatment. The occurrence of adverse reactions in the three cohorts was compared.

RESULTS: Compared with cohort C, the successful treatment rate of cohort A was significantly higher. There were statistically significant variations in the time of first exhaust/defecation, length of hospital stays, gastrointestinal decompression time, relief time of abdominal pain, and relief time of abdominal distention among the three cohorts. Compared with cohort C, cohort A’s first exhaust/defecation time, hospitalization time, gastrointestinal decompression time, abdominal pain relief time, and abdominal distension relief time was reduced (P < 0.05). After treatment, serum CRP, TNF-α, IL-6, and MCP-1 expression levels increased, and serum albumin and serum transferrin levels increased in the three cohorts. The serum albumin level in cohort A was higher than in cohort C. Compared with cohort B and cohort C, the serum transferrin level in cohort A increased (P < 0.05). Compared with cohort C, the total incidence of adverse reactions in cohorts A and B was significantly higher (P < 0.05). The incidence of adverse reactions was similar between cohort A and cohort B.

CONCLUSION: Using an ileus tube combined with meglumine diatrizoate can effectively treat postoperative inflammatory ileus obstructions after surgery colorectal cancer and improve prognosis, inflammatory response, and nutritional status.

ABSTRACT

BACKGROUND: Postoperative nursing can improve the restlessness and gastrointestinal function of patients with tracheal intubation under general anesthesia in digestive surgery. Wide application of various nursing methods and routine nursing in perioperative nursing of patients with general anesthesia in digestive surgery.

AIM: To investigate the impact of early postoperative enteral nutrition nursing based on the enhanced recovery after surgery (ERAS) theory on postoperative agitation and gastrointestinal recovery in patients undergoing general anesthesia that experienced tracheal intubation.

METHODS: The data of 126 patients with digestive surgery from May 2019 to February 2022 were retrospectively analyzed. According to different nursing methods, they were divided into control group and observation group, with 63 cases in observation group and 63 cases in control group. The patients in the control group had standard perioperative nursing care, whereas those in the observation group got enteral nourishment as soon as possible after surgery in accordance with ERAS theory. Both the rate and quality of gastrointestinal function recovery were compared between the two groups after treatment ended. Postoperative anesthesia-related adverse events were tallied, patients’ nutritional statuses were monitored, and the Riker sedation and agitation score (SAS) was used to measure the incidence of agitation.

RESULTS: When compared to the control group, the awake duration, spontaneous breathing recovery time, extubation time and postoperative eye-opening time were all considerably shorter (P < 0.05). There was no significant difference in the recovery time of orientation force between the two groups (P > 0.05); however, the observation group had a lower SAS score than the control group (P < 0.05). The recovery time for normal intestinal sounds, the time it took to have the first postoperative exhaust, the time it took to have the first postoperative defecation, and the time it took to have the first postoperative half-fluid feeding were all faster in the observation group than in the control group (P < 0.05); Fasting blood glucose was lower in the observation group compared to the control group (P < 0.05), while the albumin and hemoglobin levels were higher on the first and third postoperative days; however, there was no statistically significant difference in the incidence of anesthesia-related adverse reactions between the two groups (P > 0.05).

CONCLUSION: The extremely early postoperative enteral nutrition nursing based on ERAS theory can reduce the degree of agitation, improve the quality of recovery, promote the recovery of gastrointestinal function, and improve the nutritional status of patients in the recovery period after tracheal intubation under general anesthesia.

ABSTRACT

BACKGROUND: Patients with colorectal cancer (CRC) are prone to stress ulcer after laparoscopic surgery. The analysis of risk factors for stress ulcer (SU) in patients with CRC is important to reduce mortality and improve patient prognosis.

AIM: To identify risk factors for SU after laparoscopic surgery for CRC, and develop a nomogram model to predict the risk of SU in these patients.

METHODSThe clinical data of 135 patients with CRC who underwent laparoscopic surgery between November 2021 and June 2022 were reviewed retrospectively. They were divided into two categories depending on the presence of SUs: The SU group (n = 23) and the non-SU group (n = 112). Univariate analysis and multivariate logistic regression analysis were used to screen for factors associated with postoperative SU in patients undergoing laparoscopic surgery, and a risk factor-based nomogram model was built based on these risk factors. By plotting the model’s receiver operating characteristic (ROC) curve and calibration curve, a Hosmer-Lemeshow goodness of fit test was performed.

RESULTS: Among the 135 patients with CRC, 23 patients had postoperative SU, with an incidence of 17.04%. The SU group had higher levels of heat shock protein (HSP) 70, HSP90, and gastrin (GAS) than the non-SU group. Age, lymph node metastasis, HSP70, HSP90, and GAS levels were statistically different between the two groups, but other indicators were not statistically different. Logistic regression analysis showed that age ≥ 65 years, lymph node metastasis, and increased levels of HSP70, HSP90 and GAS were all risk factors for postoperative SU in patients with CRC (P < 0.05). According to these five risk factors, the area under the ROC curve for the nomogram model was 0.988 (95%CI: 0.971-1.0); the calibration curve demonstrated excellent agreement between predicted and actual probabilities, and the Hosmer-Lemeshow goodness of fit test revealed that the difference was not statistically significant (χ² = 0.753, P = 0.999), suggesting that the nomogram model had good discrimination, calibration, and stability.

CONCLUSION: Patients with CRC aged ≥ 65 years, with lymph node metastasis and elevated HSP70, HSP90, GAS levels, are prone to post-laparoscopic surgery SU. Our nomogram model shows good predictive value.

ABSTRACT

OBJECTIVES: We evaluated the causal effects of high-risk versus low-risk pregnancy at the first antenatal care (ANC) visit on the occurrence of complications during pregnancy and labour or delivery among women in Kenya.

METHODS: We designed a quasi-experimental study using observational data from a large mobile health wallet programme, with the exposure as pregnancy risk at the first ANC visit, measured on a binary scale (low vs high). Complications during pregnancy and at labour or delivery were the study outcomes on a binary scale (yes vs no). Causal effects of the exposure were examined using a double-robust estimation, reported as an OR with a 95% CI.

RESULTS: We studied 4419 women aged 10-49 years (mean, 25.6±6.27 years), with the majority aged 20-29 years (53.4%) and rural residents (87.4%). Of 3271 women with low-risk pregnancy at the first ANC visit, 833 (25.5%) had complications during pregnancy while 1074 (32.8%) had complications at labour/delivery. Conversely, of 1148 women with high-risk pregnancy at the first ANC visit, 343 (29.9%) had complication during pregnancy while 488 (42.5%) had complications at labour delivery. Multivariable adjusted analysis showed that women with high-risk pregnancy at the time of first ANC attendance had a higher occurrence of pregnancy during pregnancy (adjusted OR (aOR) 1.22, 95% CI 1.02 to 1.46) and labour or delivery (aOR 1.20, 95% CI 1.03 to 1.41). In the double-robust estimation, a high-risk pregnancy at first ANC visit increased the occurrence of complications during pregnancy (OR 1.23, 95% CI 1.04 to 1.46) and labour or delivery (OR 1.24, 95% CI 1.07 to 1.45).

CONCLUSION: Women with a high-risk pregnancy at the first ANC visit have an increased occurrence of complications during pregnancy and labour or delivery. These women should be identified early for close and appropriate obstetric and intrapartum monitoring and care to ensure maternal and neonatal survival.
