Introduction: This study investigated the effect of combined plant-based protein supplementation and resistance training on muscular strength, blood markers of protein catabolism, immune function, and bone metabolism in sedentary adult males. Methods: In this randomised, double-blinded study, 28 healthy males aged 19 – 29 years old were equally assigned into four groups: a combined plant-based protein with resistance training (PBPEX), plant-based protein alone (PBP), resistance training alone (EX) and control (C). Mode of resistance training was flat barbell press, machine shoulder press, wide grip lateral pull-down, seated cable row, barbell back squat, leg press and leg extension. The 8-week resistance training involved three sets of 60-70% of one-repetition maximum (1-RM) at 4-6 repetition/set/mode per session, three sessions/week. Participants in PBPEX and PBP groups consumed a plant-based protein supplement consisted of 9.8 g soy and pea protein for seven days/week. Results: PBPEX showed significant increases (p<0.01) in the knee and shoulder flexion peak torque compared to EX groups, respectively. PBP showed a significantly higher level (p<0.05) of serum urea, and blood urea nitrogen (BUN) compared to other groups. There were no changes in immune function and bone metabolism markers between pre- and post-exercise in all groups. Conclusions: These findings implied that a combination of plant-based protein supplementation and resistance training elicited greater beneficial effects on muscular strength than resistance training alone and plant-based protein supplementation alone. Therefore, combined plant-based protein with resistance training may be recommended in planning exercise and nutritional programme for sedentary male adults.

Introduction: University students’ perspectives on mental health issues remain scarce despite the growing prevalence of mental illness among this population. Therefore, this study aimed to explore university students’ perceptions
and beliefs about mental health and mental illness. Methods: Virtual in-depth interviews were conducted from December 2021 to March 2022. All interviews were audio-recorded, transcribed verbatim and analysed using thematic
analysis. Results: Sixteen informants from a Malaysian university were interviewed. Four major themes emerged:
(1) understanding of mental health and mental illness; (2) perceived causes of mental illness; (3) attitudes towards
mental illness; (4) strategies to maintain good mental health. Most informants related mental health to an individual’s
thoughts, emotions and behaviours, while a minority equated ‘mental health’ with ‘mental illness’. The majority of
informants cited socio-environmental factors as the primary cause of mental illness. Unexpectedly, informants did
not view religious factors as a cause of mental illness, although it was thought to be deeply rooted in the older generation. Nearly all informants expressed positive attitudes and willingness to help people with mental illness. However,
some informants decided to cover up their mental health problems to avoid the likelihood of experiencing negative
emotions. Most informants believed that living a fulfilling and balanced life, staying optimistic and being religious
could help them to maintain good mental health. Conclusion: To mitigate the deterioration of students’ mental
health, it is necessary to understand their perceptions and beliefs about mental health and mental illness as these
may influence their help-seeking behaviours. The study findings showed that university students have a basic understanding of mental health and mental illness and most of them are supportive in handling people with mental illness.

Microglial activity is crucial in maintaining the central nervous system (CNS) homeostasis. However, prolonged
microglial activation have been implicated in the pathology of neurodegenerative diseases. Activated microglia will
increase the production of inflammatory cytokines, reactive oxygen species (ROS) and alter their surface marker
expression levels. This study used Malaysian honey, Tualang honey (TH), and Kelulut honey (KH) to determine lipopolysaccharide (LPS)-stimulated inflammatory responses of microglia. TH and KH at 0.1% were used in the current
study as our findings showed no significant difference in the cell viability between BV2 cells treated with 0.1 % of
TH and KH and control group. TH and KH reduced the ROS level significantly by 41.62±1.06% and 49.16±0.63%,
respectively, and slightly reduced the expression of co-stimulatory molecules, CD40 and CD11b in LPS-activated
BV2 cells. Our preliminary findings proposed an in-depth future study on the anti-inflammatory effect of TH and KH
on microglial activation.

INTRODUCTION:
Three doses of SARS-CoV-2 mRNA vaccines have been recommended for cancer patients to reduce the risk of severe disease. Anti-neoplastic treatment, such as chemotherapy, may affect long-term vaccine immunogenicity.
METHOD:
Patients with solid or haematological cancer were recruited from 2 hospitals between July 2021 and March 2022. Humoral response was evaluated using GenScript cPASS surrogate virus neutralisation assays. Clinical outcomes were obtained from medical records and national mandatory-reporting databases.
RESULTS:
A total of 273 patients were recruited, with 40 having haematological malignancies and the rest solid tumours. Among the participants, 204 (74.7%) were receiving active cancer therapy, including 98 (35.9%) undergoing systemic chemotherapy and the rest targeted therapy or immunotherapy. All patients were seronegative at baseline. Seroconversion rates after receiving 1, 2 and 3 doses of SARS-CoV-2 mRNA vaccination were 35.2%, 79.4% and 92.4%, respectively. After 3 doses, patients on active treatment for haematological malignancies had lower antibodies (57.3%±46.2) when compared to patients on immunotherapy (94.1%±9.56, P<0.05) and chemotherapy (92.8%±18.1, P<0.05). SARS-CoV-2 infection was reported in 77 (28.2%) patients, of which 18 were severe. No patient receiving a third dose within 90 days of the second dose experienced severe infection.
CONCLUSION
This study demonstrates the benefit of early administration of the third dose among cancer patients.

The aim of this review was to document the recently reported prevalence and risk factors for chronic obstructive
pulmonary disease (COPD) in the last ten years. A scoping review of studies released between 2011 and 2021 was
done. The main findings on selected studies’ prevalence and risk factors were summarised. Thirty-seven studies
in total were chosen. The overall data on COPD prevalence was 1.3-36.7%, and the average incidence rate was
9.1%. The risk factors of COPD prevalence were identified as unchangeable risk factors (gender, age, family history
of respiratory and cardiovascular disease, high blood pressure, and environmental temperature and humidity) and
changeable risk factors (outdoor and indoor air pollution, cigarette smoking, occupational exposure, low education,
low household income, obesity, underweight, physical inactivity, and cooking method). The highest changeable risk
factors were cigarette smoking, indoor air pollution, and occupational exposure. In contrast, the lowest changeable
risk factors were physical inactivity and cooking methods. Changeable risk factors significantly increase COPD risks.
The COPD caused by household emissions from biofuel cooking in low-income rural areas deserves attention. Emphasis on healthy lifestyle interventions and economic and educational policies to reduce environmental impacts
may prevent COPD.
