We installed 12 alcohol gel dispensers with signs serving as behavioral nudges at a tertiary hospital in the Internal Medicine Outpatient Department (OPD), Surgery OPD, and the Pharmacy. We trained enumerators to interview outpatients and visitors regarding their behavioral drivers (beliefs about COVID-19 and hand hygiene based on the health belief model, plus handwashing social norms). We analyzed data using descriptive statistics.<br><strong>Results:</strong> Enumerators recruited 206 participants in the pre-intervention phase (refusal rate = 37.6%) and 219 participants in the post-intervention phase (refusal rate = 32.2%). There were significant differences between the pre-intervention and post-intervention phases with regard to self-efficacy for hand hygiene (92.0% vs. 100%, respectively), perceived lack of barriers to hand hygiene with alcohol (93.2% vs. 98.2%, respectively), and the proportion of participants who reported that hand hygiene had become a habit (7.5 vs. 18.8%, respectively). Reports of other domains of health beliefs (perceived severity of COVID-19, perceived benefits of handwashing) were homogeneous in both periods.<br><strong>Conclusion:</strong> We found differences in perceived lack of barriers and reported habit of hand hygiene but while self-efficacy was homogeneous in both periods. Issues regarding selection bias, construct validity, and generalizability may limit the usefulness of the study data. Caveats should be considered in the interpretation of the study findings.</p> 2021-09-10T00:00:00+07:00 Copyright (c) 2021 Author and Journal PD-1/PD-L1 Immune Checkpoint Inhibitors after Platinum-based Chemotherapy in Metastatic or Locally Advanced Urothelial Bladder Carcinoma: A Systematic Review and Meta-analysis 2021-11-17T14:16:18+07:00 Thara Tunthanathip Tanan Bejrananda <p><strong>Objective:</strong> This study aimed to assess the effect of anti-programmed cell death-1/programmed cell death-ligand-1 (PD-1/PD-L1) agents compared with second-line therapy in patients with metastatic or locally advanced urothelial bladder carcinoma following previous platinum-containing chemotherapy.<br><strong>Material and Methods:</strong> We systematically searched three electronic databases. The protocol of the study was registered in Prospero (CRD42019142494). Using the Grading of Recommendations Assessment, Development, and Evaluation approach, the certainty of evidence (CoE) was estimated.<br><strong>Results:</strong> The search results initially found 8168 publications. For qualitative synthesis, two publications were included. Pooled results indicated that patients treated with anti-PD-1/PD-L1 agents had significantly prolonged overall survival (hazard ratio (HR) 0.80; 95% confidence interval (CI) 0.7-0.9; I2 21.0%; moderate CoE). According to positive PD-L1 expression, PD-1/PD-L1 inhibitors had significantly more survival than chemotherapy (HR 0.75; 95% CI 0.5-0.9, I2 57.0%, low CoE). Furthermore, there was no significant difference in adverse events (AE) between the anti-PD-1/PDL1 agents and second-line chemotherapy (risk ratio 0.68; 95% CI 0.3-1.4; I2 97.0%, low CoE).<br><strong>Conclusion:</strong> The present meta-analysis and systematic review provide strong evidence that anti-PD-1/PD-L1 agents could improve overall survival and have similar results in AEs compared with second-line chemotherapy. Further studies will confirm the power of immunotherapy for the treatment of metastatic or locally advanced urothelial bladder carcinoma.</p> 2021-09-24T00:00:00+07:00 Copyright (c) 2021 Author and Journal TP53 Intronic Polymorphisms and Risk of Esophageal Cancer in Southern Thai Population 2021-10-20T13:33:20+07:00 Paramee Thongsuksai Pritsana Raungrut Puttisak Puttawibul Pleumjit Boonyaphiphat Wanna Sudhikaran <p><strong>Objective:</strong> The study aimed to determine the frequency of intron 3 16 base pair (bp) duplication polymorphism and intron 6 G to C substitution (G&gt;C) of the TP53 gene and to evaluate the association these two intronic variants with the risk of esophageal cancer (EC).<br><strong>Material and Methods:</strong> A case-control study was conducted to evaluate the frequency and association of cancer. Cases were patients with squamous cell carcinoma of esophagus and controls were age and sex-matched non-cancer patients. Blood samples were also obtained from healthy blood donors. Polymerase chain reaction (PCR) was used to detect intron 3 16 bp duplication and PCR-restriction fragment length polymorphism was applied to detect intron 6 G&gt;C. Logistic regression was used for the analysis.<br><strong>Results:</strong> Heterozygous intron 3 16 bp duplication (Del/Ins) was found in 10.1% (31/308) of blood donors, 9.3% (28/302) of controls and 8.6% (26/301) of EC cases. Intron 6 G&gt;C was found in 0.3% (1/308) of blood donors, in 2.6% (8/310) of controls and 3.9% (12/307) of EC cases. Both variants displayed no significant association with risk of esophageal cancer (odd ratio (OR) = 1.16 [95% confidence interval (CI) = 0.64–2.11] for intron 3 16 bp duplication and OR = 0.81 [95% CI = 0.47-4.61] for intron 6 G&gt;C.<br><strong>Conclusion:</strong> Southern Thai population have low frequency of intron 3 16 bp duplication polymorphism and intron 6 G&gt;C variant, both of which are not likely to be associated with esophageal cancer susceptibility.</p> 2021-09-24T00:00:00+07:00 Copyright (c) 2021 Author and Journal Laparoscopic Treatment of Annular Pancreas Causing Duodenal Obstruction in an Adult: A Case Report 2021-10-20T13:50:04+07:00 Suphawat Laohawiriyakamol Piyanun Wangkulangkul Worrawit Wanitsuwan Siripong Cheewatanakornkul Teeranan Laohawiriyakamol Kanet Kanjanapradit <p>Annular pancreas is a rare congenital anomaly characterized by the presence of a pancreatic tissue of variable amount which completely or partially obstructs the second part of duodenum. It usually affects infancy, but in adulthood it can mimic a wide range of clinical entity. Gastrojejunostomy or duodenojejunostomy are common operations in adults because the duodenum is less mobile. We report a case of annular pancreas in a 60-year-old male that presented with clinical condition of gastric outlet obstruction and was successfully treated with a laparoscopic Roux-en-Y gastrojejunostomy.</p> 2021-09-14T00:00:00+07:00 Copyright (c) 2021 Author and Journal Caregiver and Palliative Care 2021-10-20T13:33:23+07:00 Orapan Fumaneeshoat <p>Palliative care aims to improve the quality of life of both the palliative care patient and their caregiver. Palliative care caregivers care for palliative care patients who suffer from symptoms and unmet needs. Most reviews and research to date have focused on the palliative patient, also called the care recipient. However, we still have little knowledge about the palliative care caregivers, including the risk factors of these caregivers becoming overburdened leading to caregiver burnout. The objective of this review was to examine the responsibilities of palliative care caregivers and the associated risks of these caregivers developing caregiver burden. We review the caring work of the caregivers, the types of caregivers, the differences between palliative care and general caregivers, the different types and levels of problems they face in caring for their patients and the risk factors of developing palliative care caregiver burden. We hope this review will increase awareness of this problem and help to improve the palliative care system to look after the needs of not only the patients in the system but also the patients’ caregivers, who play such an important role.</p> 2021-09-02T00:00:00+07:00 Copyright (c) 2021 Author and Journal Reviewer Acknowledgement, 2021 2021-10-21T09:16:01+07:00 Puttisak Puttawibul 2021-10-20T00:00:00+07:00 Copyright (c) 2021 Author and Journal Author Index, Keyword Index 2021-10-21T09:15:40+07:00 Puttisak Puttawibul 2021-10-20T11:49:15+07:00 Copyright (c) 2021 Author and Journal
