This study aimed to evaluate the functional status and HRQoL in patients with primary intracranial tumours in Malaysia. Karnofsky Performance Scale (KPS) and Modified Barthel Index (MBI) were used to assess the functional status whereas EORTC core Quality of Life Questionnaire (QLQ-C30) and Brain Cancer Module (BN-20) questionnaires were used to assess the HRQoL. Thirty-eight patients with primary intracranial tumours admitted for surgery in University Malaya Medical Center were recruited. These assessments were administered before surgery (baseline) and six months after surgery (follow-up). All patients received some form of rehabilitation interventions after surgery. The global HRQoL and functional status of these patients showed improvement at six months after surgery. Emotional Functioning score showed the greatest improvement among the functional domains (63 vs 86, p=0.003). Reduction in symptom burden such as fatigue, nausea, vomiting, pain and headache were also noted at follow-up together with less future uncertainty (p<0.05). Pearson correlation revealed statistically significant positive correlation between functional status and HRQoL at baseline and follow-up, in particular, global health status (r=0.50 and r=0.67), physical functioning (r=0.53 and r=0.90) and role functioning (r=0.34 and r=0.77). Thus, from the correlation found, improving a patient's function and independence level throughout all stages of care, even before any surgical intervention is offered would improve the HRQoL concurrently.
Tilapia is one of the commercially important fish in Malaysia as well as in other parts of the world. An understanding of monogenean infection dynamics in tilapia fish may assist us in searching for some intervention measures in reducing the loss of fish caused by parasitic diseases. The present study aimed (1) to compare infection level of monogeneans between the wild and cultured Oreochromis niloticus, and between the cultured O. niloticus and cultured red hybrid tilapia, and (2) to examine the spatial distribution of monogenean species over the gills of the different host species. From a total of 75 fish specimens, six species of monogeneans from two genera: Cichlidogyrus (C. halli, C. mbirizei, C. sclerosus, C. thurstonae, C. tilapiae) and Scutogyrus (S. longicornis) were identified. Data showed that the infection level of cultured O. niloticus was higher than that of the wild O. niloticus, however, the former was lower than that of the cultured red hybrid tilapia. Higher species richness of monogeneans was observed in the cultured red hybrid tilapia as compared to the others. Results for spatial distribution showed that the monogeneans have no preference on the left or right sides of the gills. However, C. halli, C. mbirizei, and C. tilapiae showed preferences on specific gill arches in the cultured O. niloticus and red hybrid tilapia. In general, the gill arch IV harboured the least number of monogeneans. The susceptibility of monogenean infection between the different types of tilapia is discussed.
Larval descriptions of tropical marine and coastal fishes are very few, and this taxonomic problem is further exacerbated by the high diversity of fish species in these waters. Nonetheless, accurate larval identification in ecological and early life history studies of larval fishes is crucial for fishery management and habitat protection. The present study aimed to evaluate the usefulness of DNA barcodes to support larval fish identification since conventional dichotomous keys based on morphological traits are not efficient due to the lack of larval traits and the rapid morphological changes during ontogeny. Our molecular analysis uncovered a total of 48 taxa (21 families) from the larval samples collected from the Klang Strait waters encompassing both spawning and nursery grounds of marine and estuarine fishes. Thirty-two (67%) of the larval taxa were identified at the species level, two taxa (4%) at the genus level, and 14 taxa (29%) at family level. The relatively low rate of species-level identification is not necessarily due to the DNA barcoding method per se, but a general lack of reference sequences for speciose and non- commercial fish families such as Gobiidae, Blenniidae, and Callionymidae. Larval morphology remains important in species diagnoses when molecular matches are ambiguous. A lower ethanol percentage (50%) for larva preservation is also useful to keep the body of larvae intact for morphological identification, and to preserve DNA for subsequent molecular analyses. The 10% Chelex resin used to extract DNA is also cost- effective for long term monitoring of larval fishes. Hence, the DNA barcoding method is an effective and easy way to aid the identification of estuarine larval fishes at the species level.
