Background Hand-foot syndrome (HFS) is a common adverse event of capecitabine causing treatment modifications. Topical urea cream can reduce sorafenib-induced hand-foot skin reaction. However, its benefit in preventing capecitabine-associated HFS was not seen early in the course and had been unknown with long-term use. The aim of this study was to evaluate the efficacy of urea cream for HFS prophylaxis throughout capecitabine treatment. Methods Patients with cancer who received capecitabine were randomized (1:1) to receive usual care alone or in combination with urea-based cream. The incidence and degree of HFS were assessed at each capecitabine cycle. The primary endpoint was the proportion of patients with any grade HFS. The secondary endpoints included the proportion of patients with severe (≥ grade 3) HFS, modifications in capecitabine because of HFS, and HFS onset. Results After a median of six capecitabine cycles, any grade HFS was reported by 68 of 109 patients (62.4%) who received usual care and by 60 of 107 patients (56%) who used urea cream ( p  = 0.36). The patients who received usual care and urea cream had similar proportions of grade 3 HFS occurrence [52 (47.7%) vs. 44 (41.1%), respectively, p  = 0.34] and needed capecitabine modification because of HFS [20 patients (18.3%) vs. 17 patients (15.9%), respectively, p  = 0.89], as well as similar HFS onset. Conclusions Urea-based cream did not prevent capecitabine-associated HFS, reduce capecitabine modification, and delay HFS onset. However, it had a tendency to lessen HFS severity, especially in the later cycles of capecitabine.

Background During the COVID-19 outbreak, healthcare providers might have avoided droplet/aerosol-generating procedures, such as non-invasive ventilation (NIV) and high-flow nasal cannula (HFNC) due to the concern of themselves being infected. We hypothesized that this change of practice could have also occurred to other non-COVID-infected patients in the Emergency Department (ED). Methods A retrospective analytic study was conducted in the ED of Siriraj Hospital, Bangkok, Thailand, including adult patients presenting with signs and symptoms of respiratory distress between 1 March and 30 April 2020 (the COVID period). A comparison group using the same inclusion criteria was retrieved from 1 March to 30 April 2019 (the pre-COVID period). The primary outcome was rate of NIV and HFNC use. The secondary outcomes were rate of intubation, failure of NIV and HFNC, complications, and mortality. Results A total of 360 and 333 patients were included during the pre-COVID and COVID periods, respectively. After adjusting for baseline differences, patients in the COVID period were less likely to receive either NIV or HFNC than the pre-COVID period (adjusted OR 0.52 [95%CI 0.29–0.92]). Overall, intubation rate was similar between the two study periods. However, patients in respiratory distress with pulmonary edema had a relatively higher intubation rate in the COVID period. There were higher failure rates of NIV and HFNC, more infectious complications, and a higher rate of mortality in the pre-COVID period. Conclusion During the COVID-19 pandemic, the overall usage of NIV and HFNC in emergency non-COVID patients decreased. Although not affecting the overall intubation rate, this change of practice could have affected some groups of patients. Therefore, treatment decisions based on a balance between the benefits to the patients and the safety of healthcare providers should be made.

There are few data focusing on the prevalence of vitamin D deficiency in tropical countries. We determined the vitamin D status in pregnant women and examined the factors associated with vitamin D deficiency. A cross-sectional study of 147 pregnant Thai women aged 18-45 years at Siriraj Hospital (a university hospital in Bangkok, Thailand) was undertaken. Clinical data and plasma levels of 25-hydroxyvitamin D [25(OH)D], intact parathyroid hormone (iPTH), calcium, albumin, phosphate and magnesium were obtained in pregnant women at delivery. The prevalence of hypovitaminosis D [defined as 25(OH)D <75 nmol/L] in pregnant women at delivery was 75.5% (95% confidence interval (CI), 67.7-82.2%). Of these, vitamin D insufficiency [defined as 25(OH)D 50-74.9 nmol/L] was found in 41.5% (95% CI, 33.4-49.9%) and vitamin D deficiency [25(OH)D <50 nmol/L] was found in 34.0% (95% CI, 26.4-42.3%) of women. The mean 25(OH)D concentration was 61.6 ± 19.3 nmol/L. The correlation between 25(OH)D and iPTH was weak (r = -0.29, P<0.01). Factors associated with vitamin D deficiency by multiple logistic regression were: pre-pregnancy body mass index (BMI in kg/m2, odds ratio (OR), 0.88, 95% CI 0.80-0.97, P = 0.01) and season of blood collection (winter vs. rainy, OR, 2.62, 95% CI 1.18-5.85, P = 0.02). Vitamin D deficiency is common among pregnant Thai women. The prevalence of vitamin D deficiency increased in women who had a lower pre-pregnancy BMI and whose blood was collected in the winter. Vitamin D supplementation may need to be implemented as routine antenatal care.

Background: Low muscle mass is associated with worse cancer treatment outcomes. Although dual-energy X-ray absorptiometry or computerized tomography-based analysis have both been widely studied in this clinical setting, studies in the use of bioelectrical impedance analysis (BIA) remain limited. The aim of this prospective study was to investigate for association between body composition estimated by BIA and hematologic adverse events in early-stage breast cancer patients receiving chemotherapy. Methods: A total of 144 female patients were enrolled. Before the first cycle of chemotherapy, body weight and fat-free mass were measured by a BIA device and then those values were converted into body mass index and fat-free mass index. Association between fat-free mass index and composite adverse events (CAEs), including grade 4 neutropenia, febrile neutropenia, or relative dose intensity <85%, was explored. Results: CAEs occurred in 85 patients (59%), and point biserial correlation showed an inverse correlation between the fat-free mass index and CAE. No included patients were sarcopenic (fat-free mass index <11.4 kg/m2). Receiver operating characteristic curve analysis revealed <14.85 kg/m2 as the cutoff value indicating a low fat-free mass index. Using this cutoff, 85 patients were classified as having a low fat-free mass index, and 62 of those patients (72.9%) had CAE (relative risk: 1.86, P < .001). After adjusting for other factors, a low fat-free mass index was found to be independently associated with a high CAE (adjusted odds ratio: 4.562, 95% CI: 2.162-9.627, P < .001). Conclusion: Low fat-free mass index is an independent predictor of increased risk of hematologic adverse events in early-stage breast cancer patients receiving chemotherapy. Estimation of fat-free mass index by BIA may identify at-risk patients so that interventions can be considered to improve treatment outcomes.

A retrospective case-control study. To evaluate the effect of nitrous oxide and anesthetic and operative factors associated with severe pain in the early postoperative period after thoracolumbar spine surgery. Thoracolumbar spine surgery is the most common procedure in spine surgery, and up to 50% of the patients suffer from moderate to severe pain. Nitrous oxide has analgesic, anxiolytic, and anesthetic effects; nevertheless, its benefits for early postoperative pain control and opioid consumption remain to be established. The medical records of eligible participants who underwent thoracolumbar spine surgery between July 2016 and February 2017 were reviewed. Enrolment was performed consecutively until reaching 90 patients for the case (severe pain) group (patients with a pain score of >7 out of 10 at least once during the post-anesthesia care unit [PACU] admission), and 90 patients for the control (mild-to-moderate pain) group (patients with a pain score of <7 in every PACU assessment). The data collected comprised patient factors, anesthetic factors, surgical factors, PACU pain score, and PACU pain management. A total of 197 patients underwent thoracolumbar spine surgery with an incidence of early postoperative severe pain of 53.3%. The case-control study revealed no differences in the factors related to pain intensity. A subgroup analysis was performed for failed back surgery syndrome (FBSS), spinal stenosis, and spondylolisthesis. After multivariate analyses, only the age group of 19-65 years and the baseline Oswestry Disability Index (ODI) were found to be significant risk factors for early postoperative severe pain in the PACU (odds ratio [OR], 2.86; 95% confidence interval [CI], 1.32-6.25; OR, 1.03; 95% CI, 1.01-1.05, respectively). Nitrous oxide, anesthetic agents, and surgical techniques did not affect the early postoperative pain severity. Age under 66 years and the baseline ODI were the significant risk factors for pain intensity during the early postoperative period of the FBSS, spinal stenosis, and spondylolisthesis subgroups.

Purpose We assessed the efficacy of aprepitant (APR) or 10 or 5 mg OLN (OLN10 or OLN5) plus ondansetron and dexamethasone for chemotherapy-induced nausea/vomiting (CINV) prophylaxis in patients receiving high-emetogenic chemotherapy (HEC). Methods Patients who received doxorubicin + cyclophosphamide or cisplatin were given intravenous ondansetron and dexamethasone prior to chemotherapy and oral dexamethasone on days 2–4 and randomized 1:1:1 to receive APR125 on day 1 and APR80 on days 2–3 or OLN10 or OLN5 on days 1–4. Matched placebo controls were used. The primary endpoint was no nausea in ≤ 120 h. Secondary endpoints included CINV severity, complete response (CR) rate, adverse effects (AE), and quality of life. Results Of 141 patients, 104 received AC and 37 received cisplatin. The no-nausea rates were 33% (APR), 43.2% (OLN10; p  = 0.24), and 37% (OLN5; p  = 0.87). Grades 2–4 nausea were experienced by fewer patients for OLN10 than for APR (24–120 h, 8.7% vs. 27.7%, respectively; p  = 0.02; overall period, 19.6% vs. 40.4%, respectively; p  = 0.03). The median visual analog scale nausea score from 24 to 120 h was significantly lower for OLN10 (2.3) than for APR (1.2, p  = 0.03). The degrees of vomiting, CR, and AE were similar between the APR and OLN10 groups. CINV was similar between the OLN5 and APR groups. Conclusions Nausea was less severe for OLN10 than for APR in patients receiving HEC, but other measures were similar. CINV prevention efficacy was comparable between OLN5 and APR.

Forced oscillation technique (FOT) requires minimal patient cooperation and is particularly useful in young children. Bronchodilator test is a valuable tool for wheezy and asthmatic patients. The cut-off value for bronchodilator response by FOT in healthy Thai children has not been reported. To determine the cut-off values for positive bronchodilator response in healthy Thai preschool children using pseudorandom FOT. FOT was used to measure respiratory function at baseline and after 400 mcg MDI salbutamol in healthy Thai children aged 3-6 years. Respiratory resistance (Rrs) and reactance (Xrs) at 6, 8, and 10 Hz were collected. Pre- and post-bronchodilator tests were compared using paired t-test. Absolute and percent changes after bronchodilator were calculated and their cut-off values were defined as mean ± 1.96 SD. Correlation between each of those and baseline data was analyzed using Pearson's correlation coefficient. Of the 150 enrolled children, FOT measurement at baseline and after bronchodilator was successfully completed in 111 children (51 boys). The mean ± standard deviation age, height, and arm span was 5.2 ± 1.1 years, 109.3 ± 8.7 cm, and 107.2 ± 9.1 cm, respectively. No correlation was observed between any absolute or percent changes in bronchodilator response and gender, age, height, or arm span. The cut-off values established for bronchodilator response by percent change were, as follows: Rrs6: -23%, Rrs8: -20%, Rrs10: -20%, Xrs6: 36%, Xrs8: 60%, and Xrs10: 43%. The cut-off values identified in this study will be useful for evaluating bronchodilator response by FOT in wheezy and asthmatic young children.

The incidence of maternal oxygen desaturation after cesarean delivery in the postanesthesia care unit (PACU) has not been thoroughly reported. The purpose of this study was to evaluate the incidence of desaturation and to describe the frequency of supplemental oxygen administration in patients being monitored in the PACU. This study was conducted in a tertiary care hospital, and low-risk parturients undergoing cesarean delivery under spinal anesthesia were enrolled. None of the subjects received supplemental oxygen therapy on arrival at the PACU. Their oxygen saturation was continuously monitored using pulse oximetry. Desaturation was defined as an oxygen saturation at or below 94% for more than 30 seconds. The data of 324 healthy, term parturients were included in the analysis. The incidence of desaturation was only 0.3% (95% confidence interval = 0.01%-1.7%). No patient required supplemental oxygen therapy in the PACU. The incidence of postoperative oxygen desaturation in healthy parturients undergoing elective cesarean delivery under spinal anesthesia was uncommon. Routine administration of supplemental oxygen in the PACU is therefore unnecessary.The incidence of maternal oxygen desaturation after cesarean delivery in the postanesthesia care unit (PACU) has not been thoroughly reported.

Background. Few investigations preoperatively are important for low-risk patients. This study was designed to determine the level of compliance with preoperative investigation guidelines for ASA I patients undergoing elective surgery. Secondary objectives included the following: to identify common inappropriate investigations, to evaluate the impact of abnormal testing on patient management, to determine factors affecting noncompliant tests, and to estimate unnecessary expenditure. Methods. This retrospective study was conducted on adult patients over a one-year period. The institute’s guidelines recommend tests according to the patients’ age groups: a complete blood count (CBC) for those patients aged 18–45; CBC, chest radiograph (CXR) and electrocardiography (ECG) for those aged 46–60; and CBC, CXR, ECG, electrolytes, blood glucose, blood urea nitrogen (BUN), and creatinine (Cr) for patients aged 61–65. Results. The medical records of 1,496 patients were reviewed. Compliant testing was found in only 12.1% (95% CI, 10.5–13.9). BUN and Cr testings were the most frequently overprescribed tests. Overinvestigations tended to be performed on major surgery and younger patients. Overall, overinvestigation incurred an estimated cost of US 200,000 dollars during the study period. Conclusions. The need to utilize the institution’s preoperative guidelines should be emphasized in order to decrease unnecessary testing and the consequential financial burden.

The use of supplemental oxygen in uncomplicated cesarean deliveries under spinal anesthesia has been thoroughly investigated during recent decades. The aim of this study was to determine the benefits for both mother and infant of administering supplemental, low-dose oxygen via a nasal cannula versus having no supplement (i.e., room air only). Healthy parturients at term undergoing elective cesarean section under spinal anesthesia were randomly allocated into two groups: an oxygen group (n=170), who received 3 LPM oxygen via a nasal cannula; and a room-air group (n=170), who were assigned to breathe room air. Maternal oxygen saturation was measured continuously by using pulse oximeter. The desaturation was determined by oxygen saturation <94% over 30 seconds. Umbilical cord gases and Apgar scores were collected followed delivery of the infant. All maternal desaturation events occurred in 12 parturients assigned to the room-air group. Most events were concurrent with hypotension. The umbilical venous partial pressure of oxygen was significantly higher in the oxygen group. The other blood gas measurements and Apgar scores were not significantly different between the two groups. Based on our findings, the use of supplemental oxygen could prevent maternal desaturation resulting from receiving sedation and intraoperative hypotension.
