Knowledge, Attitude, and Practice Survey of Gastroparesis in Asia by Asian Neurogastroenterology and Motility Association

Gastric Myoelectrical Activity Subtypes in Functional Dyspepsia and Gastroparesis

Background/Aims

Gastric dysrhythmias, loss of normal 3 cycles per minute (CPM) gastric myoelectrical activity (GMA), and variable loss of interstitial cells of Cajal are reported both in gastroparesis (GP) and functional dyspepsia (FD). We hypothesize that the patients with GP, and FD with normal gastric emptying (NGE) and delayed gastric emptying (DGE) may vary in symptom severity, and GMA profiles.

Methods

Symptoms and their severity were evaluated by gastroparesis cardinal symptom index (GCSI), Abell scoring, short-form Nepean dyspepsia index (SF-NDI), the World Health Organization quality of life, and Rome IV subtyping for FD. Solid-meal gastric emptying was assessed by nuclear scintigraphy. Water load satiety test (WLST)-based electrogastrography determined GMA.

Results

Patients with GP (n = 40) had higher GCSI than those with FD (n = 39; [12 DGE, 27 NGE] (2.79 [2.17-3.33] vs 1.67 [0.83-2.61] vs 0.83 [0.55-1.93]; P < 0.001, in GP vs FD-NGE vs FD-DGE, respectively), severe Abell grade (Grade III in 17 [43%] vs 0% vs 0%, in GP vs FD-NGE vs FD-DGE, respectively), severe SF-NDI (80.5 [63.5-102.5] vs 50 [27-91] vs 30 [21.25-45.5]); and poor QOL. Sixteen (40%) GP had impaired gastric accommodation (< 238 mL). Post-WLST 3 CPM normal/hypernormal GMA was observed in 17 (42%), 18 (67%), and 5 (42%) patients with GP, FD (NGE), and FD (DGE), respectively; and 3 CPM hyponormal in remaining patients in each group. Post-WLST dysrhythmia was comparable.

Conclusions

WLST-electrogastrography coupled with GE study may distinguish between normal/dysrhythmic GMA revealing pathophysiologicalphenotypes of GP and FD. Analysing extent of power change in normogastric, and dysrhythmic frequencies may comprehensively elucidate disease severity.

The enjoyment of life in patients with Alzheimer's disease: correlations with caregivers' perceptions, caregiving attitudes, and empowerment levels

AIMS

This study aims to analyse the current state of life enjoyment among Alzheimer's disease patients; and explore the correlations between life enjoyment of patients with Alzheimer's disease and caregiver's knowledge of Alzheimer's disease, caregiving attitudes and caregiving empowerment.

DESIGN

This research adopted a cross-sectional study approach.

METHODS

A cross-sectional survey was conducted from May to August 2024. A convenience sampling method was employed to recruit 417 inpatients with Alzheimer'sdisease and their caregivers from tertiary-level hospitals, elderly healthcare facilities, and community welfare centres in Changsha, Hunan Province, China. The data collection tools included a general information questionnaire, the Pleasant Events Scale for Patients with Dementia (PES-AD), the Alzheimer's Disease Knowledge Scale (ADKS), the Scale of Attitude Toward with Dementia (ATD) and the Empowerment Scale for Family Caregivers with Dementia (EFCD). The SPSS27.0 software was utilized to analyse the current state and influencing factors of the life enjoyment of patients with Alzheimer's disease, and to investigate the correlations among caregivers' caregiving attitudes, caregiving empowerment, knowledge level about the disease and patients' life enjoyment.

RESULTS

Patients with Alzheimer's disease obtained scores of (17.33 ± 2.71) on the Pleasant Events Scale, (15.16 ± 2.99) on the Alzheimer's Disease Knowledge Scale, (24.70 ± 1.21) on the Scale of Attitude Toward with Dementia, and (26.88 ± 1.65) on the Empowerment Scale for Family Caregivers with Dementia. The results of the Pearson's correlation analysis indicated that there was a positive correlation between the Alzheimer's disease pleasant events of patients and the knowledge, attitude, and empowerment of caregivers regarding Alzheimer's disease (P < 0.05). The results of multiple linearregression analyses showed that patients' gender, age, self-care situations, severity of diseases, caregiver's cumulative duration of caregiving, the availability of shared caregivers, and whether caring for patients feels stress, whether or not educated about AD, knowledge of Alzheimer's disease, caregiving attitudes, and caregiving empowerment were the main influences on patients' sense of life enjoyment (P < 0.05).

CONCLUSION

The life pleasure of Alzheimer's disease patients was at a medium level; caregivers' knowledge of Alzheimer's disease was at a medium level, while their caregiving attitude and caregiving empowerment were at a medium-high level. Future research can identify the most effective interventions based on caregivers' knowledge of Alzheimer's disease. This will facilitate the enhancement of disease-related health knowledge education and training, elevate caregivers' awareness of the disease, and thereby improve the life pleasure of Alzheimer's Disease (AD) patients.

IMPACT

At present, the caregiving issues for Alzheimer's Disease Patients represents a global public health challenge, with caregiving capacity also significantly impacting patients' quality of life. Thus, in order to decelerate AD progression and improve patients' quality of life, a comprehensive analysis of caregivers' Alzheimer's Disease knowledge, caregiving attitudes, caregiving empowerment, and their correlation with patient outcomes is crucial for promoting the physical and mental health of AD patients in the future.

Prevalence of Upper Gastrointestinal Symptoms and Gastric Dysrhythmias in Diabetic and Non-Diabetic Indian Populations: A Real-World Retrospective Analysis from Electrogastrography Data

Background: Upper gastrointestinal (GI) motility disorders, such as gastroparesis and functional dyspepsia (FD), contribute significantly to morbidity, especially in populations at risk for type 2 diabetes. However, the prevalence and clinical manifestations of these disorders in India, and associated gastric dysrhythmias, are not well studied within this population. Methods: This retrospective, cross-sectional study analyzed 3689 patients who underwent electrogastrography with water load satiety test (EGGWLST) testing across multiple motility clinics in India. The prevalence of gastroparesis and FD-like symptoms, symptom severity, and their association with diabetes and other comorbidities were evaluated. Symptom severity was assessed using the Gastroparesis Cardinal Symptom Index (GCSI). EGGWLST findings were documented, including the gastric myoelectric activity threshold (GMAT) scores. Results: The study population had a mean age of 43.18 years. GCSI scores indicated that patients had symptoms that were mild (55%), moderate (33%), and severe (8%). Compared with the non-diabetic population, diabetic subjects had significantly higher rates of early satiety (56% vs. 45%, p < 0.0001), bloating (73% vs. 67%, p = 0.005), and reflux (28% vs. 24%, p = 0.029). WLST data analysis revealed that significantly more diabetic subjects ingested <350 mL (16% vs. 12%, p = 0.000016). EGG analysis revealed gastric dysthymias in one-third (65%) of patients. Significantly more diabetic subjects (22% vs. 18% p = 0.015) had a GMAT score >0.59. Conclusions: Upper GI motility disorders are prevalent in India, particularly among diabetic patients. EGG is a valuable tool for characterizing these disorders, and may help in personalizing therapeutic approaches. Further research is required to optimize treatment strategies.

Urgent appeal for expanded initiatives in gastric motility disorders across low and middle-income countries: illustrating the example of gastroparesis

This paper provides a comprehensive exploration of the current state of gastroparesis management in low and middle-income countries (LMICs), emphasising recent innovations, persistent challenges, and future prospects. Gastroparesis, a condition characterised by delayed stomach emptying, presents debilitating symptoms and is notably linked to neuropathic disorders, including diabetes mellitus. Despite an apparent higher prevalence in LMICs compared to the global average, epidemiological data remains scarce. The paper highlights pioneering research in Pakistan, Brazil, and China, showcasing a transformative shift toward comprehensive studies that delve into nuanced aspects of gastroparesis epidemiology, gender-specific patterns, and innovative therapeutic approaches such as acupuncture. However, challenges impeding clinical management and research in LMICs are identified, encompassing the absence of extensive epidemiological studies, lack of treatment guidelines, and the scarcity of specialised training programs for healthcare professionals. These challenges are intertwined with broader issues such as limited healthcare infrastructure, resource disparities, and healthcare workforce shortages. The paper proposes a multifaceted approach for addressing these challenges, involving international collaboration, capacity building, and the integration of gastroparesis management into primary healthcare services. Strategies to combat brain drain, such as collaborative agreements akin to the UK-South Africa Memorandum of Understanding, are advocated.

Prevalence and disease burden of gastroparesis in Asia

Gastroparesis is a gastrointestinal disorder characterized by significant prolongation of gastric emptying time caused by impaired motility of the stomach. Its estimated prevalence is 24.2 per 100 000 people. However, the prevalence of gastroparesis in Asian countries is unknown due to a limited number of epidemiological studies and significant phenotypic variability of the Asian population in these studies. Analysis of previous research on gastroparesis and functional bowel disorders reveals the possibility of an increased prevalence among Asian individuals. A comparison of ethnic constituents between the recent United Kingdom gastroparesis study and its mother database has demonstrated a higher prevalence of gastroparesis among British Asian patients when compared with British Caucasian patients. An estimated gastroparesis prevalence in the Asian population can be calculated by identifying the individuals who are likely to demonstrate a delayed gastric emptying from all diagnosed functional dyspepsia patients. We suggest that gastroparesis tends to be underdiagnosed in Asians due to a lack of studies on gastroparesis in the Asian continent, a lack of knowledge among practitioners, and poor availability of scintigraphy testing as well as limited therapeutic options for this disease. Given the high probability of Asian predominance in gastroparesis and its disease impact on quality of life, epidemiological research focusing on the Asian population is required.

Gastroparesis might not be uncommon in patients with diabetes mellitus in a real-world clinical setting: a cohort study

BACKGROUND

This study investigated the frequency of diabetic gastroparesis and associated risk factors in a real-world clinical setting.

METHODS

This retrospective cross-sectional study included patients who underwent assessments of solid gastric emptying time (GET) by technetium-99 m scintigraphy between May 2019 and December 2020. We categorized patients into three groups according to gastric retention of technetium-99 m: rapid (< 65% at 1 h or < 20% at 2 h), normal (≤60% at 2 h and/or ≤ 10% at 4 h), and delayed (> 60% at 2 h and/or > 10% at 4 h).

RESULTS

Patients with diabetes mellitus (DM) were more likely to show abnormal GET than those without DM (119 [70.8%] vs. 16 [44.4%]). The mean glycated A1c was 10.3% in DM patients. DM patients with normal GET were significantly younger (57.2 years, P = 0.044) than those with delayed (65.0 years) or rapid GET (60.2 years). Fasting glucose levels were the lowest in the normal GET group and the highest in the rapid GET group (delayed: 176.3 mg/dL, normal: 151.2 mg/dL, rapid: 181.0 mg/dL, P = 0.030). However, glycated A1c was not significantly different among the delayed, normal, and rapid GET groups in patients with DM. Patients with delayed and rapid GET showed a higher frequency of retinopathy (6.0 vs. 15.5%, P = 0.001) and peripheral neuropathy (11.3 vs. 24.4%, P = 0.001) than those with normal GET. In the multinomial logistic regression analysis, retinopathy demonstrated a positive association with delayed GET, while nephropathy showed a significant negative correlation.

CONCLUSION

DM gastroparesis in the clinical setting was not uncommon. Abnormal GET, including delayed and rapid GET, was associated with DM retinopathy or peripheral neuropathy.

Mediating role of learned helplessness' components in the association between health literacy/social support and self-management among maintenance haemodialysis patients in Changsha, China: a cross-sectional study

OBJECTIVES

To explore the multiple mediating roles of the learned helplessness's core system in the relationship between health literacy/social support and self-management.

DESIGN

Cross-sectional survey design.

SETTING

Changsha, China.

PARTICIPANTS

239 Chinese maintenance haemodialysis (MHD) patients.

METHODS

Two multiple mediator models were constructed based on the COM-B (Capacity, Opportunity, Motivation - Behaviour) model. A total of 239 Chinese MHD patients participated in a cross-sectional study, which included surveys on the Learned Helplessness Scale for MHD patients, Dialysis Knowledge Questionnaire, Social Support Scale and Self-Management Scale for Haemodialysis. The PROCESS macro in SPSS was used for mediated effects analysis.

RESULTS

Helplessness and internality partially mediated the relationship between health literacy/social support and self-management ((β=-0.212, p<0.01; β=0.240, p<0.01)/(β=-0.331, p<0.001; β=0.376, p<0.001)). The mediation effect size was 0.780 (95% CI (0.373 to 1.218)) in the health literacy model, accounting for 45.29% of the total effect, and 0.286 (95% CI (0.207 to 0.377)) in the social support model, accounting for 57.88% of the total effect. The differences in effect sizes for helplessness and internality in the two models were -0.080 (95% CI (-0.374 to 0.216)) and -0.041 (95% CI (-0.127 to 0.043)), respectively.

CONCLUSION

Health literacy/social support directly affects MHD patients' self-management and indirectly affects it by changing learned helplessness, such as increasing internality while reducing helplessness.

Assessing the Knowledge, Attitudes, and Vaccination Practices Towards COVID-19 Vaccination Among Mainland Chinese Nursing Students and Interns: A Multicenter Cross-Sectional Study

Objective

This study investigated factors influencing the knowledge, attitudes, practice profiles, and vaccination intentions among Chinese nursing students and nursing interns toward the coronavirus disease (COVID-19) vaccination.

Materials and Methods

The multicenter cross-sectional study was based on a self-reported questionnaire collecting information among nursing students and nursing interns from three major geographic regions of China, and the sample was selected by consecutive sampling. The questionnaire was developed by knowledge, attitudes, and practice (KAP) theory. Univariate and multivariate logistic regression were used for statistical analysis.

Results

A total of 3180 nursing students and interns (effective rate: 99.8%) from six Chinese provinces were polled. The vaccine hesitation rate was 9.65% (307/3180), 2230 participants (70.1%) had gotten at least one dose of the vaccine, and 643 participants (67.7%) had indicated a readiness to be vaccinated. The results showed that older age, higher academic background, perfect vaccine management, others' recommendations, influenza vaccination history, epidemic under control, knowledge of vaccines or intervals, and vaccine knowledge training were associated with higher vaccination rates. Conversely, vaccine hesitancy was caused by a perceived lack of physical need, uncertainty about vaccination requirements, and fear of vaccination.

Conclusion

This study provided population-based estimates of COVID-19 vaccine uptake intention among mainland Chinese nursing students and interns. Factors such as age, education, vaccine knowledge, and attitudes influence COVID-19 vaccine behaviour. Relevant authorities should understand the barriers to COVID-19 vaccination from knowledge, attitude and practice, which is significant for formulating effective response strategies in future global public health crises.

Evidence-based clinical practice guidelines for functional dyspepsia 2021

BACKGROUND

Functional dyspepsia (FD) is a disorder that presents with chronic dyspepsia, which is not only very common but also highly affects quality of life of the patients. In Japan, FD became a disease name for national insurance in 2013, and has been gradually recognized, though still not satisfactory. Following the revision policy of Japanese Society of Gastroenterology (JSGE), the first version of FD guideline was revised this time.

METHOD

Like previously, the guideline was created by the GRADE (grading of recommendations assessment, development and evaluation) system, but this time, the questions were classified to background questions (BQs, 24 already clarified issues), future research questions (FRQs, 9 issues cannot be addressed with insufficient evidence), and 7 clinical questions that are mainly associated with treatment.

RESULTS AND CONCLUSION

These revised guidelines have two major features. The first is the new position of endoscopy in the flow of FD diagnosis. While endoscopy was required to all cases for diagnosis of FD, the revised guidelines specify the necessity of endoscopy only in cases where organic disease is suspected. The second feature is that the drug treatment options have been changed to reflect the latest evidence. The first-line treatment includes gastric acid-secretion inhibitors, acetylcholinesterase (AChE) inhibitors (acotiamide, a prokinetic agent), and Japanese herbal medicine (rikkunshito). The second-line treatment includes anxiolytics /antidepressant, prokinetics other than acotiamide (dopamine receptor antagonists, 5-HT4 receptor agonists), and Japanese herbal medicines other than rikkunshito. The patients not responding to these treatment regimens are regarded as refractory FD.

Evaluating the Safety, Tolerability, and Disposition of Trazpiroben, a D2 /D3 Receptor Antagonist: Phase I Single- and Multiple-Ascending Dose Studies in Healthy Japanese Participants

Trazpiroben (TAK‐906) is a peripherally selective dopamine D₂/D₃ receptor antagonist being developed to treat chronic gastroparesis. This phase I, randomized, double‐blind, placebo‐controlled, single‐ and multiple‐ascending dose, parallel‐group study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of trazpiroben in healthy Japanese men. Findings were compared with those from a prior US trial in healthy individuals. Overall, 24 participants were enrolled into 3 cohorts (each n = 8). Per cohort, 6 participants received trazpiroben (cohort 1, 50 mg; 2, 100 mg; 3, 10 mg) once on day 1 and twice daily on days 3 through 7, and two received placebo. Trazpiroben was well tolerated, with no clinically meaningful adverse events observed. Following single‐ and multiple‐dose administration, trazpiroben was rapidly absorbed and eliminated (mean elimination half‐life, 1.89‐6.45 hours; median time to maximum serum concentration [steady state], 1.00‐1.25 hours). Serum prolactin increased with trazpiroben treatment (mean maximum serum concentration 93.32 ng/mL [10 mg] vs. 10.83 ng/mL [placebo]), illustrating receptor target engagement. Results reflected those from healthy US participants, indicating a lack of differences between these ethnic populations in trazpiroben disposition and safety profile. Trazpiroben may represent a promising therapy for chronic gastroparesis across different populations, with further evaluation ongoing in a phase IIb study (NCT03544229).

Questionnaire-Based Survey on Epidemiology of Functional Gastrointestinal Disorders and Current Status of Gastrointestinal Motility Testing in Asian Countries

BACKGROUND/AIMS

Functional gastrointestinal disorders (FGIDs) are diagnosed and classified using the latest Rome IV criteria, released in 2016. Epidemiology of FGID diagnosed by the Rome IV criteria and current clinical application of gastrointestinal motility testing in Asian countries are not well known. The aims of this survey are to elucidate the present situation of epidemiology and diagnostic tests of FGID in clinical practice in some East and Southeast Asian countries.

METHODS

The questionnaire focusing on current situation of FGID diagnosis and gastrointestinal motility testing was distributed to members of the International Gastroenterology Consensus Symposium study group and collected to be analyzed.

RESULTS

The prevalence rates of subtypes of both functional dyspepsia (FD) and irritable bowel syndrome (IBS) are relatively similar in all Asian countries. In these countries, most patients underwent both upper endoscopy and Helicobacter pylori test to diagnose FD. Colonoscopy was also frequently performed to diagnose IBS and chronic constipation. The frequency of gastrointestinal motility testing to examine gastric emptying and colonic transit time varied among Asian countries.

CONCLUSIONS

This survey revealed epidemiology of FGIDs and current status of gastrointestinal motility testing in some East and Southeast Asian countries.
