Identifying cancer patients who received palliative care using the SPICT-LIS in medical records: a rule-based algorithm and text-mining technique.

BACKGROUND: Due to limited numbers of palliative care specialists and/or resources, accessing palliative care remains limited in many low and middle-income countries. Data science methods, such as rule-based algorithms and text mining, have potential to improve palliative care by facilitating analysis of electronic healthcare records. This study aimed to develop and evaluate a rule-based algorithm for identifying cancer patients who may benefit from palliative care based on the Thai version of the Supportive and Palliative Care Indicators for a Low-Income Setting (SPICT-LIS) criteria. METHODS: The medical records of 14,363 cancer patients aged 18 years and older, diagnosed between 2016 and 2020 at Songklanagarind Hospital, were analyzed. Two rule-based algorithms, strict and relaxed, were designed to identify key SPICT-LIS indicators in the electronic medical records using tokenization and sentiment analysis. The inter-rater reliability between these two algorithms and palliative care physicians was assessed using percentage agreement and Cohen's kappa coefficient. Additionally, factors associated with patients might be given palliative care as they will benefit from it were examined. RESULTS: The strict rule-based algorithm demonstrated a high degree of accuracy, with 95% agreement and Cohen's kappa coefficient of 0.83. In contrast, the relaxed rule-based algorithm demonstrated a lower agreement (71% agreement and Cohen's kappa of 0.16). Advanced-stage cancer with symptoms such as pain, dyspnea, edema, delirium, xerostomia, and anorexia were identified as significant predictors of potentially benefiting from palliative care. CONCLUSION: The integration of rule-based algorithms with electronic medical records offers a promising method for enhancing the timely and accurate identification of patients with cancer might benefit from palliative care.

Diabetes Mellitus as Cancer Risk: A 14-year, Cross-Sectional Analysis.

Diabetes mellitus is widely thought to be a risk factors of cancers, but evidence of the association remains inconclusive, especially in Asian countries where few relevant studies have been conducted. Our study aimed to estimate overall and specific types of cancer risks among diabetes patients in Southern Thailand. Patients diagnosed with diabetes who visited the outpatient clinic of Songklanagarind Hospital during 2004 to 2018 were included. Newly diagnosed cancer patients were identified using the hospital-based cancer registry. Age-standardized incidence ratios (ASRs) and standardized incidence ratios (SIRs) were used to estimate and compare the cancer risks among diabetes patients and the general population in Southern Thailand. Of 29,314 diabetes patients identified during the study period, 1,113 patients had developed cancer. An increased risk for overall cancer was observed in both genders, with SIRs [95% CI] of 2.99 [2.65, 3.39] in men and 3.51 [3.12, 3.96] in women. Increases in the risk of several site-specific cancers including liver cancer, non-melanoma skin cancer, colon cancer and lung cancer in both sexes; prostate cancer, lymphoid leukemia, and multiple myeloma in men; and endometrial, breast, and thyroid cancer in women were observed. Our study found that diabetes generally increased the risk of both overall and site-specific cancers.

Diagnostic performance of contrast-enhanced ultrasound in diagnosing hepatic artery occlusion after liver transplantation: A systematic review and meta-analysis.

INTRODUCTION: Hepatic artery occlusion (HAO) is a significant complication post-liver transplantation. Doppler ultrasound (DUS) has been widely used as an initial screening test for detecting HAO; however, its performance is often not sufficient. Although other diagnostic tests such as computed tomography angiography (CTA), magnetic resonance angiography (MRA), and angiogram are more accurate, they are invasive and have several limitations. Contrast-enhanced ultrasound (CEUS) is an emerging tool for detecting HAO; however, the results from previous studies were limited due to a small number of patients. Therefore, we aimed to evaluate its performance by performing a meta-analysis. METHOD: We performed a systemic review and meta-analysis of studies evaluating the performance of CEUS for the detection of HAO in an adult population. A literature search of EMBASE, Scopus, CINAHL, and Medline was conducted through March 2022. Pooled sensitivity, specificity, log diagnostic odd ratio (LDOR), and area under summary receiver operating curve (AUC) were calculated. Publication bias was assessed by Deeks' funnel plot. RESULT: Eight studies were included, with 434 CEUS performed. Using a combination of CTA, MRA, angiography, clinical follow-up, and surgery as the gold standard, the sensitivity, specificity, and LDOR of CEUS for detection of HAO were .969 (.938, .996), .991 (.981, 1.001), and 5.732 (4.539, 6.926), respectively. AUC was .959. The heterogeneity between studies appeared universally low, and no significant publication bias was found (p = .44). CONCLUSION: CEUS appeared to have an excellent performance for the detection of HAO and could be considered as an alternative when DUS is non-diagnostic or when CTA, MRA, and angiogram are not feasible.

Associations between residential greenness and air pollution and the incident metabolic syndrome in a Thai worker cohort.

Increasing air pollution and decreasing exposure to greenness may contribute to the metabolic syndrome (MetS). We examined associations between long-term exposure to residential greenness and air pollution and MetS incidence in the Bangkok Metropolitan Region, Thailand. Data from 1369 employees (aged 52-71 years) from the Electricity Generating Authority of Thailand cohort from 2002 to 2017 were analyzed. The greenness level within 500 m of each participant's residence was measured using the satellite-derived Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI). The kriging approach was used to generate the average concentration of each air pollutant (PM10, CO, SO2, NO2, and O3) at the sub-district level. The average long-term exposure to air pollution and greenness for each participant was calculated over the same period of person-time. Cox proportional hazards models were used to analyze the greenness-air pollution-MetS associations. The adjusted hazard ratio of MetS was 1.42 (95% confidence interval (CI): 1.32, 1.53), 1.22 (95% CI: 1.15, 1.30), and 2.0 (95% CI: 1.82, 2.20), per interquartile range increase in PM10 (9.5 µg/m3), SO2 (0.9 ppb), and CO (0.3 ppm), respectively. We found no clear association between NDVI or EVI and the incidence of MetS. On the contrary, the incident MetS was positively associated with NDVI and EVI for participants exposed to PM10 at concentrations more than 50 µg/m3. In summary, the incidence of MetS was positively associated with long-term exposure to air pollution. In areas with high levels of air pollution, green spaces may not benefit health outcomes.

Suspected Cat-to-Human Transmission of SARS-CoV-2, Thailand, July-September 2021.

A veterinarian in Thailand was diagnosed with COVID-19 after being sneezed on by an infected cat owned by an infected patient. Genetic study supported the hypothesis of SARS-CoV-2 transmission from the owner to the cat, and then from the cat to the veterinarian.

Haematological, renal, and hepatic function changes among Rayong oil spill clean-up workers: a longitudinal study.

PURPOSE: The Rayong oil spill incident of 2013 leaked over 50,000 barrels of crude oil into the Gulf of Thailand. This study assessed trends and changes in the haematological, renal, and hepatic indices among the Rayong oil spill clean-up workers 5 years after the spill. METHODS: Haematological, renal, and hepatic indices measured for 570 oil spill clean-up workers at baseline and annually during 5-year follow-ups were analysed. Haemoglobin (Hb), haematocrit (Hct), white blood cell (WBC) count, red blood cell (RBC) count, and platelet count for haematological function, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) for hepatic function, and creatinine (Cr) and blood urea nitrogen (BUN) for renal function were assessed. The longitudinal measures of haematological, renal and hepatic indices were analysed using analysis of variance for repeated measures. The generalised estimating equations (GEE) were used to assess trends of these indices and associated factors, including exposure level. RESULTS: Increasing trends were observed per year for WBC (0.52 ± 0.03 × 103 cells/µL), Cr (0.01 ± 0.00 mg/dL), platelet (0.31 × 103 µL per year), and BUN (0.24 ± 0.03 mg/dL). Decreasing trends of aspartate aminotransferase (AST) were observed (1.54 ± 0.21 IU/L per year). Clean-up workers with high exposure to the oil spill had a significantly higher average of WBC and lower average of BUN than low-exposure and unknown-exposure workers. Gender and age were significantly associated with creatinine changes. CONCLUSION: Results of this study show the differences between baseline and follow-up haematological, renal, and hepatic indices and trends of these indices. The long-term changes in the indices in this study show worsening renal functions after oil spill and possibility of cardiovascular effects. These findings contribute to expanding knowledge on the long-term health effects of oil spills.

Hepatitis E-Associated Hospitalizations in the United States: 2010-2015 and 2015-2017.

Hepatitis E is considered rare in the United States (US) despite its widespread occurrence in Asian and African countries. The objective of this study was to describe the characteristics of hepatitis E-related pregnancies and acute-on-chronic liver failure and analyse trends for hepatitis E diagnosis among hospitalized patients in the US. We examined data from the 2010-2017 National Inpatient Sample from Healthcare Cost and Utilization Project to determine mortality, morbidity, pregnancy diagnoses, chronic liver disease diagnoses, and other conditions during hospitalization. Data were extracted for hospitalizations with hepatitis E as defined by ICD-9 codes 070.43 and 070.53 and ICD-10 code B17.2. Of 208,462,242 hospitalizations from 2010-2015, we identified 960 hepatitis E hospitalizations. The hospitalization rate of hepatitis E was 3.7 per 10 million in 2010 and 6.4 per 10 million in 2015 (ß = 0.60, p = 0.011). From 2015 to 2017, the hospitalization appeared to increase with slope (ß) of 0.50. Among those hospitalizations, 34 (4%) died and 85 (9%) had acute-on-chronic liver failure. Ninety-five (10%) had a diagnosis of pregnancy, there were no reports of maternal or foetus/neonate deaths, but there was a high proportion of adverse events for both during hospitalization. Having a chronic liver disease was associated with hepatic coma diagnosis (OR = 10.94, p = 0.002). Although the hospitalization rate of hepatitis E in the US is low, it appears to be increasing over time. Further studies are necessary in order to conclude a causal association of hepatitis E with adverse events and mortalities in pregnancy and chronic liver disease in the US.

Clinical Predictors of Morbidity and Mortality in Hospitalized Pediatric Patients With Ascites.

OBJECTIVES: Ascites is a pathologic buildup of fluid in the peritoneal cavity. Knowledge is lacking in clinical outcome in pediatric patients with ascites. We aim to identify and assess clinical variables, associated with morbidity and mortality in pediatric patients who are hospitalized with ascites. METHODS: A retrospective cohort study was performed on patients ages 0 to 21 hospitalized at Johns Hopkins Hospital between 1983 and 2010 with an ICD-9 discharge diagnosis of ascites (789.5, 789.51, 789.59). A total of 518 pediatric patients were studied, all with a diagnosis of ascites during hospitalization. Study outcomes included hospital length of stay (LOS) as a proxy for morbidity and death at hospital discharge for mortality. Variables analyzed included demographic data, ascites etiology and grade, comorbidities, and laboratory markers. Variables were analyzed by log-linear regression and competing risk model. RESULTS: Among the 3 age groups (0-5, 6-12, and 13-21), the 0 to 5 age group experienced significantly increased LOS (P < 0.001) and mortality (P = 0.027). Ascites etiology of veno-occlusive disease (VOD) and the presence of hydrothorax or thrombocytopenia was also significantly associated with increased LOS. Ascites with the etiology of congestive hepatopathy and the presence of grade 3 ascites, hepatic encephalopathy, hepatorenal syndrome, hydrothorax, hyponatremia, and thrombocytopenia were associated with increased mortality. Additionally, black pediatric patients have an increased risk of mortality (P = 0.027). Other factors including sex, leukopenia, portal vein thrombosis, and splenomegaly were not associated with LOS or mortality. CONCLUSIONS: Morbidity and mortality in pediatric patients hospitalized with ascites are associated with specific demographic and clinical factors. Further studies are required to apply this knowledge to predict the clinical outcomes.

Long-term air pollution exposure and self-reported morbidity: A longitudinal analysis from the Thai cohort study (TCS).

BACKGROUND: Several studies have shown the health effects of air pollutants, especially in China, North American and Western European countries. But longitudinal cohort studies focused on health effects of long-term air pollution exposure are still limited in Southeast Asian countries where sources of air pollution, weather conditions, and demographic characteristics are different. The present study examined the association between long-term exposure to air pollution and self-reported morbidities in participants of the Thai cohort study (TCS) in Bangkok metropolitan region (BMR), Thailand. METHODS: This longitudinal cohort study was conducted for 9 years from 2005 to 2013. Self-reported morbidities in this study included high blood pressure, high blood cholesterol, and diabetes. Air pollution data were obtained from the Thai government Pollution Control Department (PCD). Particles with diameters ≤10 µm (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and carbon monoxide (CO) exposures were estimated with ordinary kriging method using 22 background and 7 traffic monitoring stations in BMR during 2005-2013. Long-term exposure periods to air pollution for each subject was averaged as the same period of person-time. Cox proportional hazards models were used to examine the association between long-term air pollution exposure with self-reported high blood pressure, high blood cholesterol, diabetes. Results of self-reported morbidity were presented as hazard ratios (HRs) per interquartile range (IQR) increase in PM10, O3, NO2, SO2, and CO. RESULTS: After controlling for potential confounders, we found that an IQR increase in PM10 was significantly associated with self-reported high blood pressure (HR = 1.13, 95% CI: 1.04, 1.23) and high blood cholesterol (HR = 1.07, 95%CI: 1.02, 1.12), but not with diabetes (HR = 1.05, 95%CI: 0.91, 1.21). SO2 was also positively associated with self-reported high blood pressure (HR = 1.22, 95%CI: 1.08, 1.38), high blood cholesterol (HR = 1.20, 95%CI: 1.11, 1.30), and diabetes (HR = 1.21, 95%CI: 0.92, 1.60). Moreover, we observed a positive association between CO and self-reported high blood pressure (HR = 1.07, 95%CI: 1.00, 1.15), but not for other diseases. However, self-reported morbidities were not associated with O3 and NO2. CONCLUSIONS: Long-term exposure to air pollution, especially for PM10 and SO2 was associated with self-reported high blood pressure, high blood cholesterol, and diabetes in subjects of TCS. Our study supports that exposure to air pollution increases cardiovascular disease risk factors for younger population.

Systematic adaptation of the Thai version of the supportive and palliative care indicators tool for low-income setting (SPICT-LIS).

BACKGROUND: Identification of patients who might benefit from palliative care among countries with different socioeconomic and medical contexts is challenging. The Supportive and Palliative Care Indicators Tool for a Low-income Setting (SPICT-LIS) was designed to help physicians identify patients in low-income setting who might benefit from palliative care. We aimed to systematically adapt and refine the SPICT-LIS for Thai general palliative care providers. METHODS: We followed the WHO guidelines for translation, cross-cultural adaptation and validation of an instrument for the SPICT-LIS. Three expert panel members did the initial adaptation using forward and backward translations with pretested data. Two iterations of pretesting were conducted to test for applicability and reliability. The case vignettes which were used in the pretesting were modified hospital medical records. The pretesting was done with 30 respondents from various specialties in a community health center and 34 general palliative care providers from a regional referral hospital in the first and second iterations, respectively. To examine instrument reliability, interrater reliability and internal consistency were evaluated. Cognitive interviewing was conducted using semi-structured interviews with general practitioners (GPs) using the "think aloud strategy" and "probing questions". RESULTS: The adapted Thai SPICT-LIS had a total of 34 indicators which included 6 general and 28 clinical indicators. The assessment of the adapted Thai SPICT-LIS found that it provided consistent responses with good agreement among the GPs, with a Fleiss kappa coefficient of 0.93 (0.76-1.00). The administration time was 2.3-4.3 min per case. Most respondents were female. The 8 interviewed GPs said they felt that the SPICT-LIS was appropriate for use in a general setting in Thailand. CONCLUSION: The study found that the Thai SPICT-LIS could be an applicable, acceptable, and reliable tool for general palliative care providers in Thailand to identify patients who might benefit from palliative care.

Performance of echocardiography for detection of portopulmonary hypertension among liver transplant candidates: Meta-analysis.

BACKGROUND: Evaluation of pulmonary arterial pressure is crucial among cirrhotic patients, considering that moderate portopulmonary hypertension (POPH) is a contraindication for liver transplantation. Although right heart catheterization (RHC) is the most accurate method to diagnose POPH, it is invasive. OBJECTIVE: The aim of the study is to evaluate the performance of echocardiography in detecting POPH in liver transplant candidates. METHODS: A Literature search was performed, and pooled sensitivity, specificity, positive likelihood ratio (LR), negative LR, and area under the summary receiver operating curve (AUC) were calculated. Subgroup analyses were performed based on different cutoff values for echocardiography and diagnostic criteria of RHC. RESULTS: Sensitivity, specificity, positive LR, negative LR, and AUC of echocardiography for detection of POPH were 0.86 (0.74, 0.94), 0.87 (0.84, 0.90), 7.17 (3.59, 14.31), 0.22 (0.13, 0.38), and 0.807 while they were 0.82 (0.74, 0.89), 0.81 (0.78, 0.84), 117.75 (16.03, 865.08), 0.28 (0.16, 0.50), and 0.876for detection of moderate POPH, respectively. Performance of echocardiography was not significantly different in the subgroup analyses of stringency of POPH criteria and pulmonary arterial systolic pressure (ePASP) cutoffs. CONCLUSIONS: Our meta-analysis supports utilization of echocardiography for screening of POPH. However, RHC remains essential in highly suspicious cases. Echocardiographic data other than ePASP should be evaluated in future studies.

A retrospective study on the association of gastrointestinal symptoms in children with low lactase activity and low activity of other disaccharidases.

BACKGROUND: Disaccharides such as lactose and sucrose are sugars commonly found in human diet. They are broken down by mucosal disaccharidases in the duodenum. Previous small studies found no associations between gastrointestinal (GI) symptoms and combined low disaccharidase activity. We aim to explore the associations of low activity of disaccharidase and combinations of low activity of different disaccharidases with general GI symptom presentations in a large cohort of pediatric patients. METHODS: We examined a cohort (0-21 yrs.) who have undergone esophagogastroduodenoscopy and received disaccharidase activity assay from duodenal biopsy in the time period 2010 to 2012. Disaccharidase assays tested for activity of lactase, sucrase, maltase, and palatinase. GI symptoms were grouped into four categories, abdominal pain, diarrhea, weight loss, and gastroesophageal reflux. RESULTS: Of the 347 subjects, we found an association between low lactase activity and abdominal pain (OR = 1.78; 95% CI = 1.07-2.97; p < 0.05). Subjects with a lactase/sucrase ratio < 0.2 were found to be associated with abdominal pain (OR = 2.25; 95% CI = 1.25-4.04; p < 0.05), Subjects with low pandisaccharidase may be correlated with abdominal pain and have a unique frequency of GI symptoms due to low frequency of diarrhea and weight loss, but they were not statistically significant. CONCLUSIONS: Low activities of certain disaccharidase combinations may be associated with GI symptoms in subjects; a prospective study may be needed to investigate further.

Accuracy of liver stiffness, spleen stiffness, and LS-spleen diameter to platelet ratio score in detection of esophageal varices: Systemic review and meta-analysis.

BACKGROUND AND AIM: There is increasing evidence of non-invasive measurement using elastography such liver stiffness (LS), spleen stiffness (SS), and LS-spleen diameter to platelet ratio score (LSPS) for detection of esophageal varices (EV); however, data regarding comparison between these three parameters are limited. METHODS: We performed a systemic review and meta-analysis of studies evaluating performance of LS, SS, and LSPS for detection of EV and high risk/clinically significant EV (HREV). Pooled sensitivity, specificity, log diagnostic odd ratio (LDOR), and area under the receiver operating characteristic curve (AUC) of LS, SS, and LSPS for detection of EV and HREV were analyzed and compared. Publication bias was assessed by Deeks' funnel plot. RESULTS: SS and LSPS were superior to LS for detection of EV with higher sensitivity (0.90 and 0.91 vs 0.85), specificity (0.73 and 0.76 vs 0.64), LDOR (3.24 and 3.35 vs 2.26), and AUC (0.899 and 0.851 vs 0.817). For HREV, SS had the highest sensitivity (0.87) followed by LS (0.85) and LSPS (0.82); however, SS had the lowest specificity (0.52), LDOR (2.09), and AUC (0.807) whereas LSPS had the highest specificity (0.77), LDOR (2.74), and AUC (0.861). CONCLUSION: For detection of EV, we prefer using LSPS and SS over LS when available, while LS, SS, and LSPS cannot be recommended for detection of HREV due to their moderate sensitivity and specificity.

Failed Primary Bladder Exstrophy Closure with Osteotomy: Multivariable Analysis of a 25-Year Experience.

PURPOSE: Successful primary bladder exstrophy closure provides the best opportunity for patients to achieve a functional closure and urinary continence regardless of the method of repair. Use of osteotomy during initial closure has significantly improved success rates. However, failures can still occur. We identify factors that contribute to a failed primary exstrophy closure with osteotomy. MATERIALS AND METHODS: We reviewed a prospectively maintained institutional database for classic bladder exstrophy cases primarily closed with osteotomy at our institution or referred after primary closure between 1990 and 2015. Data were collected regarding patient gender, closure, osteotomy, immobilization, orthopedics and perioperative pain control. Univariate and multivariable analyses were performed to determine predictors of failure. RESULTS: A total of 156 patients met inclusion criteria. Overall failure rate was 30% (13% from our institution and 87% from referrals). On multivariable analysis use of Buck traction (OR 0.11, 95% CI 0.02-0.60, p = 0.011) and immobilization time greater than 4 weeks (OR 0.19, 95% CI 0.04-0.86, p = 0.031) had significantly lower odds of failure. Osteotomy performed by general orthopedic surgeons had significantly higher odds of failure (OR 23.47, 95% CI 1.45-379.19, p = 0.027). Type of osteotomy and use of epidural anesthesia did not significantly impact failure rates. CONCLUSIONS: Proper immobilization with modified Buck traction and external fixation, immobilization time greater than 4 weeks and undergoing osteotomy performed by a pediatric orthopedic surgeon are crucial factors for successful primary closure with osteotomy.

Ascites in Children: A Single-Center Experience of 27 Years.

OBJECTIVES: The aim of our study was to describe the changing prevalence, demographic features, etiologies, and treatment of ascites in children hospitalized during a 27-year period at the Johns Hopkins Hospital (Baltimore, MD). METHODS: We retrospectively reviewed discharges from 1983 to 2010 to select patients whose records included a diagnosis of ascites. We assessed the etiologies and degrees of ascites (ascites grade 1 detectable only by radiologic tests; ascites grades 2 and 3 recognized by moderate and marked abdominal distension by physical examinations). RESULTS: We classified 518 children into 9 etiology groups: intrahepatic disease (IH) (105), hepatic vein outflow obstruction (HVOO) (45), congestive heart disease (CH) (33), nephrotic syndrome (NS) (36), pancreatitis (26), inflammatory and infectious diseases (77), malignancy (49), idiopathic (71), and miscellaneous (76). IH and CH were predominant in the younger age group (0-5 years) versus HVOO, pancreatitis, and malignancy in the older age group (13-21 years) (P < 0.001). The prevalence of ascites increased over time from 1983 to 2006 and declined thereafter. Ascites grade 1 was more common than ascites grades 2 and 3 in all the groups (P = 0.048). IH and NS were more likely to have ascites grade 2 and 3 (P = 0.02). Although spironolactone was more frequently used in the IH group versus other etiologies, furosemide was used more frequently in NS and CH versus other etiologies (P < 0.001). CONCLUSIONS: The increased prevalence of ascites during the initial study period could reflect improved detection radiologic detection. The proportion of severe ascites and the various medical treatments differed among the etiologic groups.

Association between energy delivery from parenteral nutrition and refeeding syndrome in hospitalized adults: A retrospective cohort study.

BACKGROUND: Patients receiving parenteral nutrition (PN) may develop refeeding syndrome (RFS). This study determined RFS prevalence in hospitalized adults on PN and evaluated whether higher energy delivered by PN on day 1 of PN initiation was associated with RFS development. METHODS: We reviewed the medical records of adult patients receiving PN at a Thai quaternary hospital from June 2019 to May 2022. RFS was defined based on the Nutrition Management Clinical Practice Recommendation by the Society of Parenteral and Enteral Nutrition of Thailand. The association between PN energy delivery and RFS development was determined using a generalized estimating equation for multiple logistic regression analysis adjusted for NICE guideline risk factors. RESULTS: A total of 547 patients was included (mean age 59.8 ± 17.2 years, mean body mass index 20.7 ± 4.8 ). The prevalence of RFS was 45%. Factors associated with RFS included energy from PN on the first day of PN initiation (adjusted odds ratio [aOR] 1.17; 95% CI 1.04-1.33; for every 5 kcal/kg/day increase), starvation >5 days prior to PN (aOR 1.54; 95% CI 1.04-2.26), concomitant diuretic use (aOR 1.81; 95% CI 1.25-2.64), low baseline potassium level (aOR 1.79; 95% CI 1.19-2.70), and individual compounding PN (aOR 1.61; 95% CI 1.04-2.51). CONCLUSION: RFS was common among hospitalized patients receiving PN. The amount of energy delivered on the first day of PN was independently associated with RFS, raising a concern regarding initiation of PN with higher energy.

SARS-CoV-2 variant with the spike protein mutation F306L in the southern border provinces of Thailand.

The southernmost part of Thailand is a unique and culturally diverse region that has been greatly affected by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) outbreak during the coronavirus disease-2019 pandemic. To gain insights into this situation, we analyzed 1942 whole-genome sequences of SARS-CoV-2 obtained from the five southernmost provinces of Thailand between April 2021 and March 2022, together with those publicly available in the Global Initiative on Sharing All Influenza Data database. Our analysis revealed evidence for transboundary transmissions of the virus in and out of the five southernmost provinces during the study period, from both domestic and international sources. The most prevalent viral variant in our sequence dataset was the Delta B.1.617.2.85 variant, also known as the Delta AY.85 variant, with many samples carrying a non-synonymous mutation F306L in their spike protein. Protein-protein docking and binding interface analyses suggested that the mutation may enhance the binding between the spike protein and host cell receptor protein angiotensin-converting enzyme 2, and we found that the mutation was significantly associated with an increased fatality rate. This mutation has also been observed in other SARS-CoV-2 variants, suggesting that it is of particular interest and should be monitored.

Factors associated with the worsening of COVID-19 symptoms among cohorts in community- or home-isolation care in southern Thailand.

Introduction: This study aimed to investigate factors associated with time-to-referral due to worsening symptoms in patients with laboratory-confirmed COVID-19 in southern Thailand. While underlying diseases have been evaluated to assess COVID-19 severity, the influence of vaccinations and treatments is also crucial. Methods: A cohort of 8,638 patients quarantined in home or community isolation with laboratory-confirmed COVID-19 was analyzed. Survival analysis and the Cox proportional hazard ratio were employed to assess factors influencing time-toreferral. Results: Age ≥ 60 years, neurologic disorders, cardiovascular disease, and human immunodeficiency virus infection were identified as significant risk factors for severe COVID-19 referral. Patients who received full- or booster-dose vaccinations had a lower risk of experiencing severe symptoms compared to unvaccinated patients. Notably, individuals vaccinated during the Omicron-dominant period had a substantially lower time-to-referral than those unvaccinated during the Delta-dominant period. Moreover, patients vaccinated between 1 and 6 months prior to infection had a significantly lower risk of time-to-referral than the reference group. Discussion: These findings demonstrate early intervention in high-risk COVID-19 patients and the importance of vaccination efficacy to reduce symptom severity. The study provides valuable insights for guiding future epidemic management strategies and optimising patient care during infectious disease outbreaks.

The trend of opioid prescriptions among cancer patients in a tertiary hospital: A multimethod quantitative study.

Introduction: Pain is a major symptom in cancer patients. World Health Organization recommends opioids as the main analgesic agent. Few studies have examined the amount of opioid uses in cancer patients in Southeast Asia, however, none of them have examined the factors associated with the amount of opioid uses which were lower than required. Objectives: To assess the trends and factors associated with opioid prescriptions for cancer patients in Songklanagarind Hospital, the largest referral center in Southern Thailand. Design: Multi-method quantitative study. Methods: We reviewed the electronic medical records of 20,192, outpatients aged ≥18 years diagnosed with cancer between 2016 and 2020 who received opiod prescriptions. Oral morphine equivalents (OME) were calculated using the standard conversion factors and the OME trend during the study period was assessed by a generalized additive model. Factors affecting the morphine equivalent daily dose (MEDD) were assessed using multiple linear regression with a generalized estimating equation. Results: The mean overall MEDD for all study patients was 27.8 ± 21.9 mg per day per patient. The bone and articular cartilage cancer patients had the highest MEDD. For every 5-year increase in the duration of cancer, the MEDD increased by 0.02 (95% confidence interval [CI]: 0.01 - 0.04). Patients with stage 4 cancer received a higher average MEDD of 4.04 (95% CI: 0.30-7.62) as compared to those with stage 1 cancer. Patients with bone metastasis received a average higher MEDD of 4.03 (95% CI: 0.82-7.19) compared to those without. Age was inversely associated with the MEDD. Patients aged 42-58, 59-75 and >76years old received MEDDs of 4.73 (95% CI: 2.31-7.15), 6.12 (95% CI: 3.66-8.59) and 8.59 (95% CI: 6.09-11.09) compared with those aged 18-42 years old. Brain metastasis was inversely associated with MEDD of 4.49 (95% CI: 0.61-8.37) compared to those without. Conclusion: Opioid use in cancer patients in this study is lower than the average global usage. Promoting opioid prescriptions for pain management through medical education can help doctors overcome opiophobia.

Time-dependent incidence rates and risk factors for transferring to hemodialysis in patients on peritoneal dialysis under the Thai PD-First Policy.

BACKGROUND: Haemodialysis (HD) transfer (HDT) is the major challenge of peritoneal dialysis (PD). This study aimed to analyse the time-dependent incidence rates and risk factors for permanent HDT in patients under Thailand's PD First policy. METHODS: The records of 20,545 patients from January 2008 to June 2018 were studied. The time on therapy (TOT) was divided into 0-3, 3-12, 12-24, 24-36, 36-48 and more than 48 months. The time-dependent incidence rates and causes of PD dropout were investigated. The risk factors for HDT were analysed by multivariable Poisson regression model and presented as incidence rate ratios (IRRs) and 95% confidence intervals (CIs). RESULTS: The main cause of PD dropout was death (45.7%) with 17.4% of the patients transferred to HD. The median (25th to 75th interquartile range) dialysis vintage was 1.4 (0.5-2.7) years. The incidence rates of HDT increased with TOT. Patients with universal coverage were transferred to HD less frequently than those with other health schemes. Patients who were illiterate or only had primary school education had a higher risk of being transferred to HD after 48 months of TOT (IRR 1.41 (95% CI 1.07-1.89)). Peritonitis within the first year of PD was the risk for HDT during 13-48 months of PD. The reasons for HDT changed with TOT. Mechanical complications followed by peritonitis were the main causes of HDT during the first 3 months, and after that peritonitis was the main reason. CONCLUSIONS: The incidence of HDT increased with TOT. The risks for HDT changed over time on PD.
