Increasing incidence of musculoskeletal injuries coupled with limitations in the current treatment options have necessitated tissue engineering and regenerative medicine- based approaches. Moving forward from engineering isolated musculoskeletal tissues, research strategies are now being increasingly focused on repairing and regenerating the interfaces between dissimilar musculoskeletal tissues with the aim to achieve seamless integration of engineered musculoskeletal tissues. This article reviews the state-of-the-art in the tissue engineering of musculoskeletal tissue interfaces with a focus on Singapore's contribution in this emerging field. Various biomimetic scaffold and cellbased strategies, the use of growth factors, gene therapy and mechanical loading, as well as animal models for functional validation of the tissue engineering strategies are discussed.

Hypercholesterolemia is an important modifiable risk factor for coronary heart disease. Lifestyle changes in diet and physical activity can improve cholesterol levels. This study aimed to compare the fruits and vegetables (FV)
intake and physical activity (PA) between hypercholesterolemic adults and nonhypercholesterolemic
adults in Malaysia, and to investigate factors associated
with meeting the recommended levels of FV intake and PA in a hypercholesterolemic population. Methods: This study was based on 17,988 participants (response rate 98.7%) aged 18 years and above who responded to the hypercholesterolemia questionnaire in the 2011 Malaysian National Health and
Morbidity Survey (NHMS), a cross-sectional study with two-stage stratified sampling design. Data were obtained by trained enumerators via face-to-face interviews and were analysed by descriptive analysis, chi-square test, and
univariable and multivariable logistic regression. Results: Out of the total population assessed, 39.0% had hypercholesterolemia. The prevalence of consuming five or more servings of FV per day is low (7.8%) while 36.0% were
physically inactive among the hypercholesterolemic adults. No significant differences were observed in FV intake and PA between hypercholesterolemic and non-hypercholesterolemic populations. Gender, age and educational levels were associated with FV intake and PA among hypercholesterolemic adults. Hypercholesterolemic adults who were underweight or obese were less likely
to consume FV, while those who were former smokers and those who had diabetes and heart disease were less likely to be physically active. Conclusion: These findings are relevant for future health promotion strategies, suggesting
that more intensive interventions are needed to increase FV intake and PA level in hypercholesterolemic population and in the general population.

Solitary plasmacytoma (SPC) account for only 5% of plasma
cell neoplasms, and the literature hardly reports spinal SPC
with a neurological deficit. Furthermore, spinal surgical
intervention during pregnancy is rarely encountered and
often requires multidisciplinary collaboration and
management. The objective of this case report is to highlight
this near-miss diagnosis and spinal surgical intervention
during pregnancy. A 31-year-old woman with 24 weeks
gestation presented with sudden paralysis and incontinence,
with an underlying history of chronic backpain over a twomonth period. Initially, she was treated for musculoskeletal
back pain by obstetric colleagues during an antenatal visit,
and no radiograph was performed. A non-contrasted spinal
MRI was eventually requested when she started to show
bilateral lower limb weakness, numbness and incontinence.
The MRI highlighted thoracic vertebrae T11 vertebra plana
with kyphotic deformity and a paraspinal soft tissue mass
compressing the spinal cord causing spinal cord oedema.
Our initial working diagnosis was spinal tuberculosis (TB),
considering TB is highly endemic in Malaysia. However, TB
workup was negative, and we proceeded with spinal surgery
and transpedicular biopsy. Neurology improved significantly
after surgery. Eventually, serum protein electrophoresis
reported plasma dyscrasia, and HPE confirmed
plasmacytoma. The patient was referred to a haematologist
for steroidal and chemotherapy treatment.

Background: It is not uncommon that anxiety and
depression occur in patients with cancers, and past
researches have shown that the quality of life of patients is
negatively affected. This study aims to determine the
prevalence of anxiety and depression of patients with
haematological cancers in Malaysia and to investigate the
possible association of these psychological symptoms with
their quality of life.
Methods: This is a cross-sectional study where patients with
haematological cancers attending two major hospitals were
recruited. Anxiety and depression symptoms were assessed
using the Hospital Anxiety and Depression scale (HADS).
Quality of life (QoL) of these patients was measured using
the European Organisation for Research and Treatment of
Cancer quality of life questionnaire (EORTC QLQ C30). An
overall summary QoL score in combination with financial
difficulty score and global health score were used for
analysis.
Results: A total of 319 patients were recruited. Thirty-three
percent of patients had anxiety symptoms, 23.5% had
depression symptoms. In summary the overall score of QoL
is significantly lower in patients with higher scores for
depression and anxiety, (p<0.05). Patients who exhibit
anxiety symptoms were more frequently female, still
undergoing treatment whereas patients who had higher
depression scores were older and had acute leukemias or
myeloproliferative neoplasms. Patients who have
depression are significantly associated with a higher
financial difficulty score, p<0.05.
Conclusion: The poor quality of life in patients who have
anxiety and depression should raise awareness amongst the
health professions treating them so that additional support
can be provided.
