Objective: The successful application of gamification in different educational settings shows that the use of gamification in medical education may be an effective solution. Even though many studies have been conducted to investigate the efficacy of the integration of gamification to different education curriculums, few studies have examined the reactions, behaviors, and attitudes of learners toward the use of gamification in medical education. Hence, this study aimed to evaluate the medical students' learning experience and acceptance of the use of gamification for the delivery of electrocardiogram lessons.

Materials and methods: A qualitative research method was used to generate findings in this study. The data collection methods included focus group discussions and interviews. Triangulation methods were used to ensure the validity and reliability of the qualitative data analyzed in this study. The thematic analysis of the data collected in this study helped to garner insights into the perception of participants and experts about the use of GaMed@^™ for the delivery of ECG lessons.

Results: A total number of 32 medical students and four experts in the fields of user experience, communication, social psychology, and game design participated in this study. The findings showed that in spite of the negative reports about the user experience and application of GaMed^@™, the participants and experts affirmed its positive impact on the increased motivation and engagement of users.

Conclusions: The impact of this concept can be maximized by tailoring the game design to foster-positive learning attributes, behaviors, and outcomes in students. However, further research studies must be conducted to investigate the impact of gamification designs on specific learning outcomes in students.

Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare congenital anomaly characterized by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. Usually, such patients present with dysmenorrhea shortly after menarche, increasing pelvic pain and a palpable mass due to the obstructed hemivagina. Interestingly in the present case, the patient had her menarche seven years ago, but dysmenorrhea started only 1-year back. She never sought medical help previously as she was mostly asymptomatic all through the years. It was only after she conceived and got investigated for antenatal concerns that she was found to have HWWS. A tortuous history and an unusual clinical presentation made this case an interesting one.

Objective: To elucidate how parenting stress influence depressive symptoms in the family caregivers of children with genetic or rare diseases by examining the mediation effects of coping strategies (problem-focused, emotion-focused, and dysfunctional coping) and self-esteem.

Materials and methods: In total, 100 family caregivers were recruited and administered a questionnaire assessing demographics and study measures. We used the PROCESS for SPSS macro with 10,000 bootstrapped samples and a 95% confidence interval to test the proposed mediation models.

Results: Increased parenting stress was associated with more depressive symptoms, partially via dysfunctional coping, but not problem- or emotion-focused coping strategies. The serial multiple mediation pathway (parenting stress → low self-esteem → dysfunctional coping → depressive symptoms) was not significant, whereas the indirect effect of via dysfunctional coping alone had a significantly partial mediation effect.

Conclusions: Dysfunctional coping strategies may explain the parenting stress-depressive symptom relationship. The goals of psychosocial medical care for family caregivers were suggested.

Internal jugular vein thrombosis is a rare critical cardiovascular emergency, which has potential catastrophic clinical outcomes by resulting in stroke and pulmonary embolism. Several etiologies have been reported; however, there are limited data on Lemierre's and Trousseau's syndromes, which are both rare conditions with advanced disease progression and poor clinical outcomes. Lemierre's syndrome may present with typical progressively infectious symptoms and signs, including sore throat, neck mass, and fever, whereas Trousseau's syndrome may present with thrombophlebitis and painful edema. Without antibiotic agents controlling the infection, the condition of patients with Lemierre's syndrome may progress to sepsis or septic shock. The infection pattern plays an important role for differential diagnosis. Herein, we describe the case of a 46-year-old woman presenting with atypical symptoms of Trousseau's syndrome mimicking Lemierre's syndrome. Laboratory analysis including protein C, protein S, rheumatoid factor, and antinuclear antibody ruled out hypercoagulopathy and autoimmune vasculitis. Abdominal computed tomography and panendoscopy revealed ulcerative tumor at the antrum. Pathological examination confirmed the presence of signet-ring cell adenocarcinoma. We highlight the clinical features and etiologies of internal jugular vein thrombosis, especially in Lemierre's syndrome and Trousseau's syndrome, to aid physicians in making an early diagnosis and providing timely management.

Acute pseudo-obstruction of the colon is known as Ogilvie syndrome (OS). There are varied causes of OS. Myxedema ileus (MI) as a cause of acute pseudo-obstruction is rare. Surgery in cases of MI is reserved only in cases of cecal distension of >12 cm, bowel ischemia, and perforated bowel. We present a rare case of a 71-year-old female who was operated for abdominal compartment syndrome secondary to MI.

Objective: Nonalcoholic fatty liver (NAFLD) and chronic kidney disease (CKD) share common pathogenic mechanisms and risk factors. The relationship between in NAFLD and CKD remains controversial. We aim to assess the association between NAFLD and CKD.

Materials and methods: A cross-sectional study was based on individuals who received physical checkups at the Taipei Tzu Chi Hospital from September 5, 2005, to December 31, 2016. Demographic and clinical characteristics of the study population were collected. NAFLD was defined by abdominal ultrasonography and excluded other liver disease. CKD was defined as estimated glomerular filtration rate ≤60 mL/min/1.73 m² or the presence of proteinuria. The association between NAFLD and CKD was then analyzed using SAS software by using the multivariable logistic model. A higher prevalence of CKD was shown in individuals with NAFLD compared to those without NAFLD.

Results: In univariate analysis, individuals with mild NAFLD and moderate-to-severe NAFLD were both significantly associated with CKD (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.13-1.33; OR, 1.66; CI, 1.49-1.85) when compared to individuals without NAFLD. After multivariate adjustment, individuals with moderate-to-severe NAFLD were still significantly more likely to have CKD (OR, 1.17, 95% CI, 1.03-1.33).

Conclusions: Our finding showed that the presence and severity of NAFLD was positively associated with CKD in unadjusted and adjusted analysis. Further follow-up studies may be needed to validate these associations.

Objectives: Rhesus (Rh) blood group with variable expression of D antigen is one of the complex systems in immunohematology. Weak D antigen is a phenotype where the D antigen is weakly expressed on red blood cells, and this antigen cannot be detected by routine methods. This study was conducted to determine the frequency of Rh D negativity and weak D antigen among healthy blood donors and to review the clinical significance of weak D antigen pertaining to Rh D-negative transfusions.

Materials and methods: This cross-sectional prospective study was conducted in G. B Pant Hospital from January 2016 to June 2017 in which all the blood donors from Port Blair and adjacent islands of Andaman and Nicobar were grouped for Rh D antigen and those who tested negative for the D antigen were further tested for weak D antigen by incubating for 30 min and subsequent addition of anti-human globulin sera.

Results: Out of 6415 donors, 6085 (94.86%) were Rh D positive and 330 (05.14%) were Rh D negative. Among the Rh D-negative donors, 05 (01.51%) were positive for weak D antigen. The frequency of Rh D negativity was 25.76% in a blood group, 25.15% in B, 07.88% in AB and 41.21% in O blood group phenotype.

Conclusion: Although the frequency of weak D antigen is low (01.51%), the strong immunogenicity of Rh D antigen discernates the need for appropriate testing for weak D antigen. This is of particular concern in Rh D-negative pregnant females as it can produce alloimmunization if accidentally given weak D antigen positive blood.

Objective: Recently, an alarming rise of dengue has been seen in India which remains a major public health concern. This study has been designed for a comprehensive overview of the epidemiology, gender, age, area distribution, symptomology, and seasonal variability.

Materials and methods: Retrospective analysis of 900 suspected dengue cases of all age groups of either sex from 2012 to 2017 at a North Indian tertiary care hospital revealed 461 (51.22%) cases seropositive for dengue.

Results: The age group of 20-30 years was the most affected group with male predominance. The urban population was more affected as 75.05%, and maximum cases were detected in October month followed by November. Common abnormal laboratory parameters were thrombocytopenia (99.1%), hepatic dysfunction (59%), and leukopenia (26.68%). Two uncommon findings, pancytopenia and pancreatic dysfunction were reported in 7 and 3 cases respectively.

Conclusion: Dengue infection in India has evolved rapidly, and regular outbreaks have been observed with a changing epidemiology, as the disease is rapidly spreading from urban to rural areas with increasing atypical manifestations.

Objective: The objective of this study was to evaluate the efficacy of mirabegron 25 mg daily in patients with nocturia-predominant hypersensitive bladder (HSB).

Materials and methods: This study prospectively investigated 219 consecutive patients with nocturia-predominant HSB and treated with mirabegron 25 mg daily from July 2015 to 2016. Patient with nocturia episode decreased by ≥1/night after treatment was considered successful. The subjective symptom score, such as International Prostate Symptom Score (IPSS), Quality of life index, Overactive Bladder Symptom Score (OABSS), Urgency Severity Scale, patient perception of bladder condition (PPBC), and nocturia episodes per night, was assessed before and 1 month after mirabegron treatment and between successful and failed groups.

Results: A total of 219 patients, including 51 women and 168 men, were enrolled. The mean age of the population was 72.3 ± 11.0 years. Totally, 58 (26.5%) of the patients had improvement in nocturia at 1 month after treatment. Among them, 14 (27.5%) women and 44 (26.2%) men had improvement in nocturia episodes after treatment (P = 0.858). Compared the clinical data between successful and failed group, the baseline symptom scores were more severe in successful group, including IPSS-storage subscore (4.84 ± 2.09 vs. 4.11 ± 2.19, P = 0.031), OABSS (3.21 ± 0.67 vs. 2.91 ± 1.00, P = 0.037), and nocturia episodes (3.81 ± 0.95 vs. 3.095 ± 1.32, P = 0.000). Multivariate analysis revealed only a higher nocturia episodes (P = 0.046) predict a successful treatment result. Mirabegron 25 mg daily significantly improved PPBC score along the 3 months' follow-up (P < 0.05), and postvoid residual volume did not increase after mirabegron treatment in overall patients.

Conclusions: Mirabegron 25 mg daily treatment showed a limited therapeutic effect on nocturia-predominant HSB patients. The patients with higher OAB symptoms predict a successful result.

Objective: Adiponectin is a fat-derived hormone that secretes exclusively by adipocytes and has antiatherosclerotic effects. Peripheral arterial occlusive disease (PAOD) is associated with an increased risk of death in hemodialysis (HD) patients. The aim of this study was to evaluate the relationship between serum adiponectin levels and PAOD by ankle-brachial index (ABI) in HD patients.

Materials and methods: Blood samples were obtained from 100 HD patients. Serum adiponectin levels were measured using a commercial enzyme-linked immunosorbent assay kit. ABI values were measured using the automated oscillometric method (VaSera VS-1000). ABI values that <0.9 were included in the low ABI group.

Results: Among the 100 HD patients, 18 of them (18.0%) were in the low ABI group. Compared with patients in the normal ABI group, the patients in the low ABI group had a higher prevalence of diabetes (P = 0.043), older age (P = 0.027), and lower serum adiponectin level (P = 0.003). In addition, the multivariable logistic regression analysis showed that adiponectin (Odds ratio [OR]: 0.927, 95% confidence interval [CI]: 0.867-0.990, P = 0.025) and age (OR: 1.054, 95% CI: 1.002-1.109, P = 0.043) were the independently associated with PAOD in HD patients.

Conclusion: In this study, serum adiponectin level was found to be associated with PAOD in HD patients.
