Presence and characterization of blaNDM-1-positive carbapenemase-producing Klebsiella pneumoniae from outpatients in Thailand.

BACKGROUND: Presently, community-associated carbapenemase-producing Enterobacterales (CPE) remains largely unknown and require public attention. This study aimed to investigate the presence of CPE from outpatients in Thailand. METHODS: Non-duplicate stool (n = 886) and urine (n = 289) samples were collected from outpatients with diarrhea and urinary tract infection, respectively. Demographic data and characteristics of patients were collected. Isolation of CPE was performed by plating enrichment culture on agar supplemented with meropenem. Carbapenemase genes were screened by PCR and sequencing. CPE isolates were phenotypically and genotypically characterized. RESULTS: Fifteen samples (1.3%, 14 stool and 1 urine) yielded blaNDM-1-positive carbapenemase-producing Klebsiella pneumoniae (CPKP). Additional resistance to colistin and tigecycline was observed in 53.3% and 46.7% of isolates, respectively. Age >60 years was identified as a risk factor for patients with CPKP (P < 0.001, adjusted odds ratio = 11.500, 95% confidence interval = 3.223-41.034). Pulsed field gel electrophoresis revealed genetic diversity of CPKP isolates; however, clonal spread has been observed. ST70 (n = 4) was common, followed by ST147 (n = 3). blaNDM-1 from all isolates were transferable and mainly resided on IncA/C plasmid (80%). All blaNDM-1 plasmids remained stable in bacterial host for at least 10 days in antibiotic-free environments, regardless of replicon types. CONCLUSION: This study demonstrates that the prevalence of CPE among outpatients in Thailand remains low and the spread of blaNDM-1-positive CPKP may be driven by IncA/C plasmid. Our results emphasize the need for a large-scale surveillance study to limit further spread of CPE in community.

Prevalence and predictors of peripheral arterial disease determined by ankle brachial index in diabetes population treated within primary care services in a non-urban area of lower northern Thailand.

In diabetes patients, urban lifestyle has been concerned as one of the risk factors for peripheral arterial disease (PAD). The aims of this study were to find out the prevalence and associated risk factors of PAD in type 2 diabetes patients who live in a non-urban community area. A total of 885 participants with type 2 diabetes mellitus were enrolled from six primary care units in the health network centered at Naresuan University Hospital, Phitsanulok, between May and June 2018. Ankle-brachial index (ABI) was performed in all subjects using a vascular screening device. PAD was defined by an ABI value of 0.9 or lesser at least on one leg. The predictors of PAD were analyzed using multiple logistic regression. The prevalence of PAD was 7.2% among 884 evaluable patients. Diabetic neuropathy and a history of macrovascular complications were significant predictors of PAD.

Situational analysis of palliative care education in thai medical schools.

OBJECTIVE: The Thai Medical School Palliative Care Network conducted this study to establish the current state of palliative care education in Thai medical schools. METHODS: A questionnaire survey was given to 2 groups that included final year medical students and instructors in 16 Thai medical schools. The questionnaire covered 4 areas related to palliative care education. RESULTS: An insufficient proportion of students (defined as fewer than 60%) learned nonpain symptoms control (50.0%), goal setting and care planning (39.0%), teamwork (38.7%), and pain management (32.7%). Both medical students and instructors reflected that palliative care education was important as it helps to improve quality of care and professional competence. The percentage of students confident to provide palliative care services under supervision of their senior, those able to provide services on their own, and those not confident to provide palliative care services were 57.3%, 33.3%, and 9.4%, respectively. CONCLUSIONS: The lack of knowledge in palliative care in students may lower their level of confidence to practice palliative care. In order to prepare students to achieve a basic level of competency in palliative care, each medical school has to carefully put palliative care content into the undergraduate curriculum.
