Significance of Ongoing Training and Professional Development in Optimizing Healthcare-associated Infection Prevention and Control.

The employees who work in infection prevention and control (IPC) are very important in the field of health-care because they are committed to protecting patients, staff, and visitors from the risk of acquiring infections while in the hospital. The complexity of infection control in hospitals is alwaysgrowing in tandem with the rapid developments that are being made in medical technology andpractices. IPC personnel are required to maintain vigilance and continually improve their monitoringof the entire health-care process due to the ongoing development of IPC guidelines and regulations, the fluctuating infection risks, and the emergence of new infectious diseases. As a result, individuals involved in the prevention and control of infections in health-care settings absolutely need to participate in continual training and professional development. This reviewemphasizes the need of relevant professionals to engage in ongoing training and professional development to maintain their skills in the area of healthcare-associated infection control and prevention. Personnel working in IPC may more effectively react to newly discovered health risks andmake certain that hospital infection (HI) management gets the appropriate attention if they have atimely and in-depth awareness of best practices. They are better able to maintain their composure, react correctly, and deliver the most effective infection control and prevention techniques for the health-care system, all while increasing awareness about the significance of effective HI management.

Predictors of Self-Reported Hand Hygiene Performance among Nurses at Tertiary Care Hospitals in East Coast Malaysia.

BACKGROUND: Hand hygiene (HH) is the simplest and most effective way to reduce the incidence of healthcare-associated infections (HCAIs). METHODS: This cross-sectional study aimed to determine factors associated with self-reported HH performance among nurses at Kelantan tertiary care hospitals. A sample of 438 registered nurses was selected through a stratified random sampling method. Self-reported HH performance was assessed using a validated WHO self-administered HH knowledge and perception questionnaire for healthcare workers. RESULTS: A multiple linear regression analysis was performed to identify the predictors. The factors that significantly predicted self-reported HH performance among nurses included perception score (beta coefficient (ß) = 0.260; 95% CI: 0.200, 0.417; p < 0.001), pediatric department (ß = -0.104; 95% CI: -9.335, -2.467; p < 0.001), and orthopedic department (ß = -5.957; 95% CI: -9.539, -0.720; p < 0.023), adjusted R2 = 0.102; p < 0.001. Nurses with a strong perception and belief in HH were more likely to have better HH performance. Compared to pediatric and orthopedic, surgical departments were associated with better self-reported HH performance. CONCLUSIONS: This study showed the importance of factors that could improve the intervention's performance in HH strategy. Lack of perception and HH program intervention in departments engaged in patient care could lead to poor HH practices, thus increasing HCAIs and antimicrobial resistance (AMR).

Genotypic Detection of rpoB and katG Gene Mutations Associated with Rifampicin and Isoniazid Resistance in Mycobacterium Tuberculosis Isolates: A Local Scenario (Kelantan).

BACKGROUND: Drug resistant tuberculosis (DR-TB) remains a public health issue that is of major concern on a global scale. The characterisation of clinical isolates may provide key information regarding the underlying mechanisms of drug resistance, and helps to augment therapeutic options. This study aims to evaluate the frequency of gene mutations associated with Rifampicin (RIF) and Isoniazid (INH) resistance among nine clinical isolates. METHODS: A total of nine drug resistant Mycobacterium tuberculosis clinical isolates were screened for genetic mutations in rpoB and katusing polymerase chain reaction (PCR) amplification and DNA sequencing. Genotypic analysis was performed to detect the mutations in the sequence of the target genes. RESULTS: Our findings reveal that 80% of the isolates possess mutations at codon 119 (His119Tyr) and 135 (Arg135Trp and Ser135Leu) within the rpoB gene; and 70% possess mutations in the katG gene at codon 238 with amino acid change (Leu238Arg). CONCLUSION: Findings from this study provide an overview of the current situation of RIF and INH resistance in a hospital Universiti Sains Malaysia (HUSM) located in Kelantan, Malaysia, which could facilitate molecular-based detection methods of drug-resistant strains. Further information regarding the molecular mechanisms involved in resistance in RR-/MDR-TB should be addressed in the near future.

Updates on Knowledge, Attitude and Preventive Practices on Tuberculosis among Healthcare Workers.

Ranking as the most communicable disease killer worldwide, tuberculosis, has accounted with a total of 9.6 million new tuberculosis cases with 1.5 million tuberculosis-related deaths reported globally in 2014. Tuberculosis has remain as an occupational hazard for healthcare workers since 1920s and due to several tuberculosis outbreaks in healthcare settings in the early 1990s, the concern about the transmission to both patients and healthcare workers has been raised. Healthcare workers have two to three folds greater the risk of active tuberculosis than the general population. Several studies on knowledge, attitude and practices on tuberculosis among healthcare workers worldwide have revealed that majority of the participated healthcare workers had good knowledge on tuberculosis. Most of the healthcare workers from South India and South Africa also reported to have positive attitude whereas a study in Thailand reported that most of the healthcare providers have negative attitude towards tuberculosis patients. Nevertheless, majority of the healthcare workers have low level of practice on tuberculosis prevention. An improved communication between healthcare workers and the patients as well as their families is the key to better therapeutic outcomes with good knowledge, attitude and preventive practice towards tuberculosis.

Antituberculosis potential of some ethnobotanically selected Malaysian plants.

AIM OF THE STUDY: Many local plants are used in Malaysian traditional medicine to treat respiratory diseases including symptoms of tuberculosis. The aim of the study was to screen 78 plant extracts from 70 Malaysian plant species used in traditional medicine to treat respiratory diseases including symptoms of tuberculosis for activity against Mycobacterium tuberculosis H37Rv using a colorimetric microplate-based assay. MATERIALS AND METHODS: Plant extracts were prepared by maceration in methanol (80%) and antituberculosis screening was carried out using Tetrazolium bromide microplate assay (TEMA) method to determine the minimum inhibitory concentration (MIC). RESULTS: Thirty-eight plant extracts from 36 plant species exhibited antituberculosis activity with MICs in the range of 1600-400 µg/ml. The leaf extract of Angiopteris evecta exhibited the highest activity with MIC of 400 µg/ml. Five other extracts, namely, Costus speciosus (stem and flower), Piper sarmentosum (whole plant), Pluchea indica (leaf), Pluchea indica (flower), and Tabernaemontana coronaria (leaf) exhibited antituberculosis activity, each with MIC of 800 µg/ml. To the best of our knowledge, this is the first report of in vitro high throughput screening of Malaysian medicinal plants for antituberculosis activity. CONCLUSIONS: Antituberculosis activity of extracts of some plants justifies, to a certain extent their ethnomedicinal uses as remedies for symptoms of tuberculosis. These results also support the general view that, selecting the plants based on ethnobotanical criteria would enhance the probability of finding species with antituberculosis activity.
