The gap between expectations and reality could lead to low job satisfaction. Although much literature has been described on job satisfaction among different categories of people, more research is needed to acknowledge the judgment of job satisfaction among some of the Myanmar working population. The study aims to find out the satisfaction level of a job and the factors related to it. The cross-sectional study was conducted in January 2019 by calling for face-to-face interviews with 536 respondents selected using a convenient sampling technique using a pre-tested questionnaire. The highest satisfied respondents were >50 years age group (86.11%), females (71.89%), higher officials (90.53%), and more than three years of service (78.35%). In the adjusted analysis, having 41-50 year age group (AOR 2.72; 95% CI: 1.08-6.83), part-time job nature (AOR 2.16; 95% CI: 1.17-3.99), and the higher official (AOR 5.71; 95% CI: 2.48-13.13) were significantly associated with job satisfaction. Relationships with the direct executive and, organization and management were the main determinants of job satisfaction. Moreover, the respondents with higher positions were more likely to have higher job satisfaction in the study.

Prostatic urethra identification is crucial in prostate stereotactic body radiotherapy (SBRT) to reduce the risk of urinary toxicity. Although computed tomography (CT) with a catheter is commonly employed, it is invasive, and catheter placement may displace the urethral position, resulting in possible planning inaccuracies. However, magnetic resonance imaging (MRI) can overcome these weaknesses. Accurate urethral identification and minimal daily variation could ensure a highly accurate SBRT. In this study, we investigated the usefulness of a three-dimensional (3D) T2-weighted (T2W) sequence for urethral identification, and the interfractional motion of the prostatic urethra on CT with a catheter and MRI without a catheter for implementing noninvasive SBRT. Thirty-two patients were divided into three groups. The first group underwent MRI without a catheter to evaluate urethral identification by two-dimensional (2D)- and 3D-T2W sequences using mean slice-wise Hausdorff distance (MSHD) and Dice similarity coefficient (DSC) of the contouring by two operators and using visual assessment. The second group provided 3-day MRI data without a catheter using 3D-T2W, and the third provided 3-day CT data with a catheter to evaluate the interfractional motion using MSHD, DSC, and displacement distance (Dd). The MSHD and DSC for the interoperator variability in urethral identification and visual assessment were superior in 3D-T2W than in 2D-T2W. Regarding interfractional motion, the Dd value for prostatic urethra was smaller in MRI than in CT. These findings indicate that the 3D-T2W yielded adequate prostatic urethral identification, and catheter-free MRI resulted in less interfractional motion, suggesting that 3D-T2W MRI without a catheter is a feasible noninvasive approach to performing prostate SBRT.

We aimed to explore the correlations of high molecular weight adiponectin (HMW-ADP), tumor necrosis factor-alpha (TNF-α) and vascular endothelial growth factors (VEGFs) with the occurrence of colonic polyps in the prediabetic population. Two hundred patients with prediabetes were enrolled, and their clinical data were retrospectively analyzed. They were divided into group A (75 patients with colonic polyps) and group B (125 patients without colonic polyps). Eighty patients with normal glucose tolerance in the same period were divided into group C (32 patients with normal glucose tolerance and colonic polyps) and group D (48 patients with normal glucose tolerance but no colonic polyps). The correlations of serum HMW-ADP, TNF-α and VEGF levels with plasma glucose and insulin levels were explored by Pearson's analysis. The factors influencing the occurrence of colonic polyps were determined by logistic regression analysis. Serum HMW-ADP was negatively correlated with TNF-α, VEGFs, FPG, 2hPG, FI and HOMA-IR (r<0, P<0.05), whereas serum TNF-α and VEGFs were positively correlated with FPG, 2hPG, FI and HOMA-IR (r>0, P<0.05). Age, body mass index, waist-to-hip ratio, history of smoking, history of drinking, family history of colon cancer, TNF-α and VEGF were independent risk factors [odds ratio (OR)>1, P<0.05], and HMW-ADP was a protective factor (OR<1, P<0.05). The areas under the curves of serum HMW-ADP, TNF-α, VEGFs and their combination for predicting the occurrence of colonic polyps were 0.899, 0.787, 0.908 and 0.922, respectively. The combination of HMW-ADP, TNF-α and VEGFs can effectively predict the occurrence of colonic polyps in prediabetic patients.

Centralization of childhood cancer treatment in specialized hospitals is necessary for quality treatment and care, but imposes a time and cost burden for patients and their families. We investigated the 20-year trend in the patients' car travel burden to reach cancer-care hospitals in Aichi Prefecture, Japan. From the Aichi population-based cancer registry data, 1,741 cases diagnosed in 1998-2017 under 15 years of age were extracted and assigned to three treatment groups: invasive treatment (n = 697), radiotherapy (n = 371), or chemotherapy groups (n = 1,462), allowing for duplicate assignment. Their travels to access each treatment hospital were estimated and summarized as the estimated travel times (ETT), estimated travel distances (ETD), and direct distances (DD). The ETTs were compared using the Brunner-Munzel test. The average cases per year for each hospital were plotted. The annual trends during 1998-2017 on ETT, ETD, and DD were investigated using Joinpoint regression models. The ETTs were 0.38-0.45 hours on median for three periods (1998-2005, 2006-2012, and 2013-2017) in three treatment groups and increased by 0.02-0.07 hours from 2006-2012 to 2013-2017, with a statistically significant difference in the radiotherapy group (0.07 hours, P = 0.037). The average cases per year increased for the top hospital in each group, and regression model analyses showed no joinpoint on the annual median trend. In conclusion, the increases in travel times were small and not considered clinically significant, and treatment centralization was observed from 2006-2012 to 2013-2017.

Acute exacerbation (AE) of interstitial pneumonia (IP) shows poor prognosis, due to the typical histological pattern of diffuse alveolar damage superimposed upon lung fibrosis. The previous reports comparing clinical features between AE of idiopathic interstitial pneumonias (IIPs) and those of IPs with known etiology are limited. We retrospectively compared clinical parameters including age, sex, Charlson Comorbidity Index score (CCIS), blood biomarkers at diagnosis of AE, treatment, and 3-month mortality between patients with AE of IIPs and collagen vascular disease-associated interstitial pneumonia (CVD-IP). We assessed 85 patients, comprising 66 patients with AE of IIPs (78%) and 19 patients with AE of CVD-IP (22%). The least absolute shrinkage and selection operator regression selected CCIS (hazard ratio, 1.281; 95% confidence interval, 1.055-1.556; P = 0.012) and log serum lactate dehydrogenase (LDH) (hazard ratio, 6.267; 95% confidence interval, 2.172-18.085; P < 0.001) as significant predictors of 3-month mortality among these patients. Also, the adjusted survival curves using sex, CCIS, and serum LDH showed no significant differences between these two groups. In conclusion, among AE patients, CCIS and serum LDH level may be more important prognostic factors for 3-month mortality rather than two classification of IP subtypes: IIPs and CVD-IP.

We investigated the associations among neurological severity, activities of daily living (ADLs), and clinical factors in patients with ischemic stroke in convalescent rehabilitation outcome. The study sample included 723 patients with ischemic stroke (484 men and 239 women; mean age, 73.2 ± 8.5 years) for inpatient convalescent rehabilitation. National Institutes of Health Stroke Scale (NIHSS) was used to measure the neurological severity, and Functional Independence Measure (FIM) was used to assess ADLs at discharge. Leukoaraiosis was graded based on periventricular hyperintensity (PVH) and deep white matter hyperintensity (DWMH) on magnetic resonance imaging. The correlations between NIHSS scores and total FIM scores were significant but relatively mild (r = -0.684, P < 0.001). Multiple regression analysis revealed that age and PVH grade significantly decreased their total FIM scores and affected the discrepancies between NIHSS scores at discharge (P < 0.001), but DWMH scores did not affect these results. Factors such as positive history of heart disease (P = 0.008) and bilateral infarction (P = 0.038) additionally decreased their total FIM scores and affected the discrepancies between NIHSS scores. These findings suggest that age, PVH, history of heart disease positive, and bilateral infarction in patients with ischemic stroke affected their performance of ADLs and the discrepancies between their neurological severities in convalescent rehabilitation outcomes, probably because the pathophysiological background of leukoaraiosis and these factors strongly decrease their ADL performance in post-phase ischemic stroke.

Ustekinumab has recently been approved for the treatment of ulcerative colitis (UC) based on data from clinical trials. However, the effectiveness of ustekinumab in patients with UC in a real-world setting remains unclear. Hence, in this meta-analysis, we aimed to evaluate the effectiveness of ustekinumab in a real-world setting and to investigate the predictors of its effectiveness. A comprehensive literature search was performed to examine the effectiveness of ustekinumab in UC patients admitted between January 2019 and December 2021. Data on clinical remission, response, and corticosteroid-free clinical remission rates were extracted, pooled, and analyzed. Meta-regression analysis was performed to investigate the source of heterogeneity and the impact of moderators on the outcomes of interest. A total of 14 eligible studies were identified. The pooled clinical remission rate was 55.0% at week 8, 36.1% at week 16, 46.6% at month 6, and 38.6% at month 12. The meta-regression analysis showed that prior use of anti-tumor necrosis factor (TNF) agents and vedolizumab and the publication style were significant moderators. Additionally, out of 258 patients, there were 28 adverse events (AEs) (10.9%). The effectiveness of ustekinumab in real-world patients with UC was consistent with the results clinical trials. Moreover, previous treatment with anti-TNF agents and vedolizumab might have affected the effectiveness of ustekinumab.

Necrotizing fasciitis is a rapidly progressive, life-threatening soft tissue infection that needs acute surgical intervention and other types of supportive care. The upper extremities are a less frequent site for this infection than the lower extremities. Axillary necrotizing fasciitis is quite rare and bears a high risk of iatrogenic neurovascular injuries. We report a severe case of a 39-year-old man with a right axillary necrotizing fasciitis caused by Streptococcus pyogenes. While dealing with important nerves and blood vessels at the initial emergency surgery, we marked and preserved them with vascular tapes. The patient underwent several surgical interventions for infection control in addition to supportive care to avoid limb loss and to survive. Intraoperatively, the locations of nerves and vessels could be easily found by checking the vessel tapes. Twelve months after the initial admission, the patient had no symptoms of nerve injuries and resumed work. With necrotizing fasciitis, the risk of an iatrogenic nerve injury exists even if limb amputation is avoided due to repeated debridement. We report that marking and preserving nerves and blood vessels with vascular tapes at the initial surgery may make the subsequent ones easier and may reduce iatrogenic neurovascular injury.

We evaluated the efficacy and safety of an endoscope-embedded transvaginal laser hyperthermia system for superficial cervical cancer that remained in the cervix after radiotherapy. We developed an innovative endoscope-embedded hyperthermia system consisting of a diode laser device, a temperature control unit, an endoscope control unit, and a transvaginal probe. Superficial lesions of recurrent or residual cervical cancer on the uterine cervix or vaginal wall after radiotherapy were eligible for this study. A total of four cases of three patients were eligible for this treatment. Case 1: The post-chemoradiotherapy residual tumor of a patient with stage IIB squamous cell carcinoma of the cervix was treated with the device. Two months after the laser hyperthermia treatment, the tumor's disappearance was confirmed. Case 2: A post-hysterectomy persistent tumor on the vaginal stump of a patient with stage IIB adenocarcinoma of the cervix was subjected to the laser hyperthermia treatment. Two months after the treatment, the stump's cytology was false positive. Case 3: As in case 2, this patient's recurrence in the anterior vaginal wall was subjected to laser hyperthermia treatment, but the tumor's growth was not controlled. Case 4: A tumor at the vaginal margin was identified during a salvage hysterectomy in a patient with stage IIB squamous cell carcinoma of the cervix who underwent chemoradiotherapy. After laser hyperthermia treatment, the tumor's disappearance was confirmed. Our new endoscope-embedded laser hyperthermia system can be a candidate for treating residual superficial cervical cancer after radiotherapy by accurately capturing superficial lesions.

At our hospital, we are conducting the "Clinical Study of a Patient-Specific Cardiac Support Net for Dilated Cardiomyopathy (jRCTs042180025)", a multi-facility clinical study of a customized cardiac support net (CSN). Here, we describe the cardiac rehabilitation (CR) of a heart failure (HF) patient after CSN treatment. The patient was a 65-year-old man who exhibited dilated cardiomyopathy (DCM) because of left ventricular non-compaction; his New York Heart Association status was class III. In November 2019, he received CSN treatment. The early CR program was adapted for this patient, and his postoperative course was uneventful. Functional measurements showed improved leg-muscle strength (before treatment: 61.4% BW; at discharge: 77.3% BW). During long-term follow-up, the patient's exercise tolerance increased, as shown by 6-minute walk distance (before treatment: 576 m; long-term follow-up: 600 m) and peak oxygen uptake (before treatment: 12.5 mL/kg/min; long-term follow-up: 13.3 mL/kg/min). In the 2 years since discharge, the patient has not been hospitalized for HF. This report is the first to show that the CSN can be used to perform a CR program in a DCM patient without significant functional decline.
