INTRODUCTION: Despite the exponential increase in microbiome research, knowledge and beliefs about the gut microbiome and faecal microbiota transplantation (FMT) remain unclear. The aim of this study was to identify the extent of knowledge, awareness and perception among the general public regarding the gut microbiome and FMT. METHODS: An online questionnaire on knowledge and beliefs about the gut microbiome and FMT was administered to 1831 participants. Data analysis software was used to generate descriptive statistics and explore associations between knowledge and sociodemographic variables. RESULTS: Even though only 33% of participants had heard of the gut microbiome, more than 92% had consumed probiotic drinks or supplements. While 85% had not heard of the FMT procedure, 72% of respondents would consider having FMT to treat Clostridioides difficile infection (CDI). Willingness to receive FMT depended mainly on recommendation from healthcare providers (77%). Knowledge and awareness regarding the gut microbiome and FMT were relatively low, despite most participants having prior gut health-related behaviours. CONCLUSION This study identified the public's perceptions of FMT and the potential barriers to its uptake. Insights from the study highlight the need for health education to enhance acceptance of FMT and the importance of using information supported by medical professionals to immunise the public against poorly validated science.

Background/Aims: The effect of peroral endoscopic myotomy (POEM) on esophageal body movement in achalasia is poorly understood. This study aims to evaluate morphological changes in esophageal body movement after POEM in type III achalasia by analyzing intraluminal ultrasound (US) images in comparison to type I and II achalasia. Methods: Intraluminal US images and impedance values of the distal esophagus from 47 achalasia patients who underwent POEM or pneumatic dilatation (PD) (30 patients in the POEM group and 17 patients in the PD group) with pre- and post-procedural high-resolution impedance manometry and intraluminal US examinations were analyzed. The muscle thickness (MT), muscle cross-sectional area, lumen cross-sectional area (LCSA), contractility and distensibility indices, swallow-to-distension interval, and distension duration during each bolus transport were analyzed. Results: The MT increased and LCSA decreased significantly (P < 0.001), but the contractility index was not improved after POEM or PD in type I achalasia. Baseline MT increased and LCSA decreased significantly after POEM and PD in type II achalasia (P < 0.001). In contrast, MT and the swallow-to-distension interval decreased and the distension LCSA/duration and contractility index increased after POEM in type III achalasia (P < 0.001). In contrast to type I and II achalasia, in type III achalasia, these effects were unique to the POEM group. Conclusions POEM decreased the esophageal LCSA by decreasing intrabolus pressure without improving contractility in type I and II achalasia. In contrast, POEM increased esophageal body distension and contractility and improved the inhibitory process during bolus transport in type III achalasia.

Background: and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year. Methods: We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020). Results: There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths. Conclusions During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.

Background: and PurposeAcute colonic pseudo-obstruction (ACPO) is a common but understudied complication in neurocritically ill patients. The acetylcholinesterase inhibitor neostigmine can be used to treat ACPO in patients who do not respond to conventional treatment. This study investigated the effectiveness and adverse events when using neostigmine to manage ACPO in neurocritically ill patients. Methods: This retrospective study investigated patients with ACPO who were treated using neostigmine in the neurological intensive-care units at two centers between March 2017 and August 2020. Neostigmine was administered intravenously or subcutaneously (at doses ranging from 0.25 mg to 2 mg) according to the protocols at the two centers. The outcomes were bowel movements and the changes in colon diameters on abdominal radiographs. Safety events such as bradycardia, vomiting, salivation, and sweating were evaluated. Results: This study included 31 subjects with a mean age of 46.8 years (65.4% males). All patients had a bowel movement at a median of 120 minutes after administering neostigmine. The colon diameter decreased by a median of 17.5 mm (paired t-test: p<0.001) regardless of the dose and treatment protocols. Multilevel analysis confirmed that the mean colon diameter decreased from 66 mm pretreatment to 47.5 mm posttreatment (p<0.001), with an intraclass correlation coefficient of 13%. Three patients (9.7%) exhibited hypersalivation, sweating, bradycardia, and vomiting. Bradycardia (heart rate, 42 beats/minute) occurred in one patient (3.2%), and was successfully managed by injecting atropine. Conclusions Neostigmine injection is a safe and effective treatment option for ACPO in neurocritically ill patients who fail to respond to conservative management.

The oculocardiac reflex is a trigeminal-vagal reflex that manifests as cardiac arrythmias, most often bradycardia. The reflex can be triggered by manipulation of periorbital structures and unintended pressure on the bulbus oculi maxillofacial procedures. In this brief communication, we describe an unusual trigger of the oculocardiac reflex during maxillofacial surgery that resulted in severe bradycardia. This case highlights the need for careful securement of medical devices and attention to surgical technique to avoid undue pressure on draped fascial structures.

Background: Despite the lack of official COVID-19 statistics, various workplaces and occupations have been at the center of COVID-19 outbreaks. We aimed to compare legal measures and governance established for managing COVID-19 infection risks at workplaces in nine Asia and Pacific countries and to recommend key administrative measures. Methods: We collected information on legal measures and governance from both general citizens and workers regarding infection risks such as COVID-19 from industrial hygiene professionals in nine countries (Indonesia, India, Japan, Malaysia, New Zealand, Republic of the Philippines, Republic of Korea, Taiwan, and Thailand) using a structured questionnaire. Results: A governmental body overseeing public health and welfare was in charge of containing the spread and occurrence of infectious diseases under an infectious disease control and prevention act or another special act, although the name of the pertinent organizations and legislation vary among countries. Unlike in the case of other traditional hazards, there have been no specific articles or clauses describing the means of mitigating virus risk in the workplace that are legally required of employers, making it difficult to define the responsibilities of the employer. Each country maintains own legal systems regarding access to the duration, administration, and financing of paid sick leave. Many workers may not have access to paid sick leave even if it is legally guaranteed. Conclusion Specific legal measures to manage infectious disease risks, such as providing proper personal protective equipment, education, engineering control measures, and paid sick leave are recommended to be stipulated in Industrial safety and health-related acts.
