OBJECTIVE: The aim is to evaluate the levels of knowledge, attitude, and practice among emergency HCW of the COVID-19 resuscitation protocol by the European Resuscitation Council (ERC).

METHODS: A cross-sectional study using a validated questionnaire was conducted among HCW in the emergency department of University of Malaya Medical Centre (UMMC), Malaysia from April to June 2021.

RESULTS: A total of 159 respondents were included in the analysis (89% response rate). Sixty-eight percent of respondents had adequate knowledge regarding COVID-19 resuscitation. Majority of the respondents had knowledge on airborne-precaution personal protective equipment (PPE) (99%) and infection control measures (98%). Nearly 73% were pessimistic about the COVID-19 prognosis. Seventy-three percent of respondents thought an arrested COVID-19 patient may benefit from cardiopulmonary resuscitation (CPR) and 94% were willing to administer CPR provided airborne-precaution PPE was available. Ninety percent of respondents reported adherence to resuscitation guidelines. There were significant differences in the mean knowledge scores between designation, education levels, and COVID-19 training. Overall, the respondents' level of practice was insufficient (27%), with a mean score of 53.7%(SD = 14.7). There was a lack of practicein the resuscitation oftheintubatedand patients who were beingprone. There was insufficient practice about ventilation technique, use ofsupraglotticdevices, and intubation barriers. There was a positive correlation between adequate knowledge and good practice.

MATERIALS AND METHODS: A total of 144 samples were divided into four groups, a control group (n = 12) and three test groups, nanosilica (NS) (n = 36), nanoalumina (NA) (n = 36), and a hybrid nanoparticle (HySA) (n = 60) at different weight percentages (1, 2, and 3 wt. %) was added to Tech-sil25. Samples were exposed to artificial weathering for 100 hours, and subjected to characterizations involving tear strength, shore A hardness, roughness, and tensile strength tests. The data were analyzed using descriptive and inferential statistics using a one-way ANOVA test to determine the level of significance between the groups.

RESULTS: After 100 hours of artificial weathering, the one-way ANOVA result shows a highly significant increase in tensile and tear strengths with a minimal increase in hardness and roughness observed in samples containing 2% nanosilica (NS) followed by hybrid nanoparticle (HySA) of 1% nanoalumina (NA) + 1% nanosilica (NS) compared with a control group and other groups.

METHODOLOGY:  A cohort study was conducted among workers who had a stroke in northeastern Malaysia. They were assigned either to undergo robotic or conventional rehabilitation therapy. The robotic therapy is performed three times per day for four weeks. Meanwhile, conventional therapy involved walking exercises five days per week for two weeks. Data were collected for both therapies on the admission, at week 2 and week 4. The MBI, modified Rankin Scale (mRS) and Hospital Anxiety and Depression Scale (HADS) trends were examined one month after the therapies. The R (version 4.2.1) (R Core Team, Vienna, Austria) and RStudio (R Studio PBC, Boston, USA) were applied to perform the descriptive analyses on the respective platforms. Repeated measures of analysis of variance were performed to evaluate the outcomes trend and the effectiveness of the two therapies was also compared.

RESULTS: A total of 54 stroke patients participated in this study of which 30 (55.6%) of them received robotic therapy. The age of the subjects ranged from 24 to 59 years and the majority (74.1%) were male. Stroke outcomes were evaluated using mRS, HADS, and MBI scores. Except for their age, the individuals' characteristics did not significantly differ between those undergoing conventional therapy and those receiving robotic therapy. After four weeks, it was found that the good mRS had increased, whereas the poor mRS had decreased. Comparing the therapy groups, the MBI scores improved significantly with time, although there were no significant differences between the therapy groups. However, the interaction term between the treatment group (p=0.031) and improvements over time was significant (p=0.001), indicating that robotic was more effective than conventional therapy in improving the MBI scores. For HADS score, there was a significant difference between the therapy groups (p=0.001), with those receiving robotic therapy having higher HADS score.

METHODS: Nationally representative data of Malaysia were used to generate cross-sectional evidence. The sample size was 2156 respondents. An ordered probit regression was utilized to assess factors associated with the practice of physical activity.

RESULTS: Respondents aged 40-49 years with hypertension were 7.3% less likely to participate in high-level physical activity when compared to those without hypertension. The probability of having a low level of physical activity was 12.3% higher among hypertensive patients aged ≥60. Males, married individuals, less-educated adults, low-income earners, and individuals who were aware of their BMI, had a higher tendency to indulge in a highly active lifestyle than others.
