    Autosomal recessive interleukin (IL)-12 p40 (IL-12p40) deficiency is a rare genetic etiology of mendelian susceptibility to mycobacterial disease (MSMD). We report the genetic, immunologic, and clinical features of 49 patients from 30 kindreds originating from 5 countries (India, Iran, Pakistan, Saudi Arabia, and Tunisia). There are only 9 different mutant alleles of the IL12B gene: 2 small insertions, 3 small deletions, 2 splice site mutations, and 1 large deletion, each causing a frameshift and leading to a premature stop codon, and 1 nonsense mutation. Four of these 9 variants are recurrent, affecting 25 of the 30 reported kindreds, due to founder effects in specific countries. All patients are homozygous and display complete IL-12p40 deficiency. As a result, the patients lack detectable IL-12p70 and IL-12p40 and have low levels of interferon gamma (IFN-γ). The clinical features are characterized by childhood onset of bacille Calmette-Guérin (attenuated Mycobacterium bovis strain) (BCG) and Salmonella infections, with recurrences of salmonellosis (36.4%) more common than recurrences of mycobacterial disease (25%). BCG vaccination led to BCG disease in 40 of the 41 patients vaccinated (97.5%). Multiple mycobacterial infections were rare, observed in only 3 patients, whereas the association of salmonellosis and mycobacteriosis was observed in 9 patients. A few other infections were diagnosed, including chronic mucocutaneous candidiasis (n = 3), nocardiosis (n = 2), and klebsiellosis (n = 1). IL-12p40 deficiency has a high but incomplete clinical penetrance, with 33.3% of genetically affected relatives of index cases showing no symptoms. However, the prognosis is poor, with mortality rates of up to 28.6%. Overall, the clinical phenotype of IL-12p40 deficiency closely resembles that of interleukin 12 receptor β1 (IL-12Rβ1) deficiency. In conclusion, IL-12p40 deficiency is more common than initially thought and should be considered worldwide in patients with MSMD and other intramacrophagic infectious diseases, salmonellosis in particular.

    BACKGROUND: Information about elderly breast cancer patients' outcome is limited. This study aimed to evaluate the treatment outcomes in women aged 70 and above with specific analysis on prognostic clinicopathological features and treatment modalities.

    MATERIALS AND METHODS: This retrospective study examined breast cancer patients between 1st January 1994 and 31st December 2004 in UMMC. Survival analysis was performed using the Kaplan-Meier method and comparisons between groups using the log-rank test. Univariate and multivariate analysis on prognostic factors were carried out using the Cox's proportionate hazard model for patient demographics, and tumour and treatment factors.

    RESULTS: One hundred and thirty six patients were identified, with a median age at diagnosis of 75 years. Most had at least one co-morbidity (61.8%). Only 75.0% had a good performance status (ECOG 0-1). Mean tumour size was 4.4 cm. Primary tumour stages (T stages) 3 and 4 were present in 8.1% and 30.1% of patients respectively, and 30.9% had stage III and 8.8% had stage IV disease based on overall AJCC staging. ER positivity was 58.1%. PR status was positive in 30.1%. Surgery was performed in 69.1% of the patients and mastectomy and axillary clearance were the commonest surgical procedures (50.7%). Some 79.4% of patients received hormonal therapy, 30.1% radiotherapy and only 3.6% chemotherapy. Non-standard treatment was given to 39.0% of patients due to a variety of reasons. The cumulative 5 years overall, relapse free and cause specific survivals were 51.9%, 79.7% and 73.3% respectively. Performance status, T3-4 tumour, presence of metastasis, tumour grade and ER status were independent prognostic factors for overall survival. For cause specific survival they were T4 tumour, presence of metastasis and ER status.

    CONCLUSION: The 5 years overall survival rate was 51.9% and 41.8% of deaths were non-breast cancer related deaths. Low survival rate was related to low life expectancy in this population. Locally advanced disease, metastatic disease and high ER negative rates play a major role in the survival of elderly breast cancer patients in Malaysia.

    INTRODUCTION: Diffuse large B-cell lymphoma (DLBCL) is the most common aggressive type of non-Hodgkin lymphoma with variable clinical outcomes. The immunogenotypic features of this heterogeneous disease in Malaysia were not well characterized.

    MATERIALS & METHODS: In total 141 local series of DLBCL cases from UKM Medical Centre were retrospectively studied.

    RESULTS: Of these cases, we classified our patients into two subtypes: 32.7% (37/113) GCB and non-GCB 67.3% (76/113) by Hans algorithm and the results showed strong agreement with the results by Choi algorithm (κ = 0.828, P<0.001). Survival analysis indicated significant difference in between GCB and non-GCB subtypes (P=0.01), elevated serum LDH (P=0.016), age more than 60-year-old (P=0.021) and the presence of B symptoms (P=0.04). We observed 12% DLBCL cases were CD5 positive and 81.8% of them died of the disease (P=0.076). Analysis on the dual expression of MYC/BCL2 revealed that there is no significant difference in DE and non-DE groups (P=0.916). FISH study reported there were 9.22% (13/141) rearranged cases observed in our population at which highest frequency of BCL6 gene rearrangement (76.9%), followed by MYC (15.4%) and BCL2 (7.7%); no BCL10 and MALT-1 gene rearrangement found regardless of using TMAs or whole tissue samples. More cases of MYC protein overexpression observed compared to MYC translocation.

    CONCLUSION: Relatively lower frequency of GCB tumours and low gene rearrangement rates were observed in Malaysian population. A national study is therefore warranted to know better the immunogenotypic characteristics of DLBCL in Malaysia and their implications on the survival.

    The ability to cope with infection by a parasite is one of the major challenges for any host species and is a major driver of evolution. Parasite pressure differs between habitats. It is thought to be higher in tropical regions compared to temporal ones. We infected Drosophila melanogaster from two tropical (Malaysia and Zimbabwe) and two temperate populations (the Netherlands and North Carolina) with the generalist entomopathogenic fungus Beauveria bassiana to examine if adaptation to local parasite pressures led to differences in resistance. Contrary to previous findings we observed increased survival in temperate populations. This, however, is not due to increased resistance to infection per se, but rather the consequence of a higher general vigor of the temperate populations. We also assessed transcriptional response to infection within these flies eight and 24 hours after infection. Only few genes were induced at the earlier time point, most of which are involved in detoxification. In contrast, we identified more than 4,000 genes that changed their expression state after 24 hours. This response was generally conserved over all populations with only few genes being uniquely regulated in the temperate populations. We furthermore found that the American population was transcriptionally highly diverged from all other populations concerning basal levels of gene expression. This was particularly true for stress and immune response genes, which might be the genetic basis for their elevated vigor.

    There has been a worldwide surge in the number and severity of dengue in the past decades. In Singapore, relentless vector control efforts have been put in to control the disease since the 1960's. Space spraying, fogging, chemical treatment and source reduction are some commonly used methodologies for controlling its vectors, particularly Aedes aegypti. Here, as we explored the use of a commercially available delthamethrin-treated net as an alternative strategy and the efficacy of the treated net was found to be limited. Through bioassays and molecular studies, the failure of the treated net to render high mortality rate was found to be associated with the knockdown resistance (kdr) mutation. This is the first report of kdr- mutations in Singapore's Ae. aegypti. At least one point mutation, either homozygous or heterozygous, at amino acid residue V1016G of DIIS6 or F1269C of DIIIS6 was detected in 93% of field strains of Ae. aegypti. Various permutations of wild type and mutant amino acids of the four alleles were found to result in varying degree of survival rate among local field Ae. aegypti when exposed to the deltamethrin treated net. Together with the association of higher survival rate with the presence of both V1016G and F1269C, the data suggest the role of these mutations in the resistance to the deltamethrin. The high prevalence of these mutations were confirmed in a country wide survey where 70% and 72% of the 201 Ae. aegypti analysed possessed the mutations at residues 1016 and 1269 respectively. The highest mutated frequency combination was found to be heterozygous alleles (VG/FC) at both residues 1016 and 1269 (37.8%), followed by homozygous mutation at allele 1269 (24.4%) and homozygous mutation at allele 1016 (22.9%). The kdr- type of resistance among the vector is likely to undermine the effectiveness of pyrethroids treated materials against these mosquitoes.

    Molecular profiling of breast cancer has enabled the development of more robust molecular prognostic signatures and therapeutic options for breast cancer patients. However, non-Caucasian populations remain understudied. Here, we present the mutational, transcriptional, and copy number profiles of 560 Malaysian breast tumours and a comparative analysis of breast cancers arising in Asian and Caucasian women. Compared to breast tumours in Caucasian women, we show an increased prevalence of HER2-enriched molecular subtypes and higher prevalence of TP53 somatic mutations in ER+ Asian breast tumours. We also observe elevated immune scores in Asian breast tumours, suggesting potential clinical response to immune checkpoint inhibitors. Whilst HER2-subtype and enriched immune score are associated with improved survival, presence of TP53 somatic mutations is associated with poorer survival in ER+ tumours. Taken together, these population differences unveil opportunities to improve the understanding of this disease and lay the foundation for precision medicine in different populations.

    Chromosome 7 aberrations in renal cell carcinoma (RCC) have been reported in papillary renal cell carcinoma (pRCC) and clear cell renal cell carcinoma (ccRCC). However, the implication of these anomalies on prognosis and survival is still unclear. RCC Chromosome 7 aberrations have commonly been detected by fluorescent in situ hybridization and chromogenic in situ hybridization but not silver in situ hybridization (SISH).

    OBJECTIVE: Kelantan in Malaysia has a high prevalence of diabetes and colorectal cancer is also on the rise. This study is to determine the association of metabolic diseases, particularly diabetes type 2 [DM2] and hypertension, with colorectal cancer patients in our population.

    METHODS: This retrospective study was conducted on all colorectal carcinomas in Hospital Universiti Sains Malaysia (HUSM) in Kelantan from ythe ears 2001-2006. The data were retrieved from the Registry in Pathology laboratory and the clinical details from the patients' clinical records and analyzed using SSPS Version 12.0, with a value of p<0.05 taken to be statistically significant.

    RESULTS: 138 CRC cases with complete clinical records were included. The age ranged from 16.0 to 88.0 years, with a mean of 56.9 -/+ SD 15.4. The male 90(65%) to female 48(35%) ratio was 1.7:1.0 and 47.8% were suffering from metabolic diseases; 18(13.0%) with Diabetes Mellitus Type 2(DM2), and 48(34.8%) with hypertension (HT). Diabetes Type 2 and hypertension also demonstrated significant association (p<0.05) with the stage and the site of the cancer. Patients with diabetes type 2 88.8%(16/18) and Hypertension 85.4% (41/48) were strongly associated with cancers located in the distal to transverse colon (p<0.001).

    CONCLUSION: There is a high proportion of metabolic diseases; hypertension and diabetes type 2 among colorectal carcinomas seen in Kelantan population. In this preliminary study we noted a strong association of metabolic diseases with the stage and site of the cancer. To reduce CRC incidence, the high prevalence of DM2 in Kelantan needs to be addressed.

    OBJECTIVE: To determine the trend of cancer cases in one major hospital in Kelantan over a 20 year period from 1987 to 2007 and to speculate the change in trend due to the socio-economic and other health status in the state.

    METHODOLOGY: All data on clinically diagnosed cancer cases in Hospital Universiti Sains Malaysia [HUSM] were retrieved from the hospital medical records. The cancers were classified according to ICD10 and scrutinized to avoid duplicate or more entries. The increment in cancer incidence was calculated based on total numbers of cancer cases per each 5-6 year period.

    RESULTS: A total of 12,228 solid cancers were diagnosed during the period. There is an increment of 20.1% for 1991-1996 from 1987-1990 period, 67.4% for 1997-2001 from 1991-1996 period and 305.9% for 2002-2007 from the 1997-2001 period. The rise was steep in the last 5-6 years. After excluding referred cases from states outside Kelantan, the increments were 20.1%, 67.4% and 143.6% for the consecutive 5-6 year periods. The predominant rising trends were seen for cancers of the female organs, digestive tract and endocrine organs.

    CONCLUSION: Cancer cases in HUSM are showing a rising trend, associated with increasing prevalence of smoking, obesity and diabetes in the community served by the hospital. Since HUSM is the only hospital managing cancer in the state of Kelantan, to reduce cancer incidence in the state, life-style issues need to be addressed.

    OBJECTIVE: To study the impact of various clinicopathological factors on short-term survival in a cohort of breast cancer patients treated at the University of Malaya Medical Centre (UMMC).
    METHODS: All cases of breast cancer treated at UMMC from January 1999 to June 2001, except for stage IV disease, were included in the study. Survival analysis was carried out using Kaplan-Meier for univariate analysis and Cox regression for multivariate analysis. The log-rank test was used to test the significance of differences between the different survival curves.
    RESULTS: A total of 385 patients were included. The mean patient age at presentation was 50.3 years (SD, 11.4); 198 (51.4%) patients had lymph node-positive disease, and 187 (48.6%) had node-negative disease. The mean follow-up period was 18.7 months (SD, 8.8). The Malay ethnic group, tumours of larger size, node-positive disease, more than five positive lymph nodes, oestrogen receptor (ER) negativity and the presence of lymphovascular invasion were significant prognostic factors for shorter recurrence-free survival (RFS) in the univariate analysis. In the multivariate analysis, ER negativity was the only independent adverse prognostic factor for RFS. For overall survival (OS), tumours of larger size, node-positive disease, more than five positive lymph nodes, ER negativity and high grade tumours were associated with significantly shorter OS. However, more than five positive lymph nodes was the only independent prognostic factor for shorter OS in the multivariate analysis. Further multivariate analysis of the patients with node-positive disease showed that the Malay ethnic group, ER negativity and more than five positive lymph nodes were independent prognostic factors for shorter RFS. On the other hand, ER negativity and more than five positive lymph nodes were independent negative prognostic factors for OS in this subgroup of patients.
    CONCLUSION: The evaluation of various prognostic factors would provide useful information on disease progression in local patients, especially for the planning of adjuvant therapies and follow-up protocols. Differences in the pattern of breast cancer among the different ethnic groups in Malaysia warrant further studies.

    OBJECTIVE: Cure rate models are survival models, commonly applied to model survival data with a cured fraction. In the existence of a cure rate, if the distribution of survival times for susceptible patients is specified, researchers usually prefer cure models to parametric models. Different distributions can be assumed for the survival times, for instance, generalized modified Weibull (GMW), exponentiated Weibull (EW), and log-beta Weibull. The purpose of this study is to select the best distribution for uncured patients' survival times by comparing the mixture cure models based on the GMW distribution and its particular cases.

    MATERIALS AND METHODS: A data set of 91 patients with high-risk acute lymphoblastic leukemia (ALL) followed for five years from 1982 to 1987 was chosen for fitting the mixture cure model. We used the maximum likelihood estimation technique via R software 3.6.2 to obtain the estimates for parameters of the proposed model in the existence of cure rate, censored data, and covariates. For the best model choice, the Akaike information criterion (AIC) was implemented.

    RESULTS: After comparing different parametric models fitted to the data, including or excluding cure fraction, without covariates, the smallest AIC values were obtained by the EW and the GMW distributions, (953.31/969.35) and (955.84/975.99), respectively. Besides, assuming a mixture cure model based on GMW with covariates, an estimated ratio between cure fractions for allogeneic and autologous bone marrow transplant groups (and its 95% confidence intervals) were 1.42972 (95% CI: 1.18614 - 1.72955).

    CONCLUSION: The results of this study reveal that the EW and the GMW distributions are the best choices for the survival times of Leukemia patients.

    OBJECTIVE: Cure models are frequently used in survival analysis to account for a cured fraction in the data. When there is a cure rate present, researchers often prefer cure models over parametric models to analyse the survival data. These models enable the ability to define the probability distribution of survival durations for patients who are at risk. Various distributions can be considered for the survival times, such as Exponentiated Weibull Exponential (EWE), Exponential Exponential (EE), Weibull and lognormal distribution. The objective of this research is to choose the most appropriate distribution that accurately represents the survival times of patients who have not been cured. This will be accomplished by comparing various non-mixture cure models that are based on the EWE distribution with its sub-distributions, and distributions distinct from those belonging to the EWE distribution family.

    MATERIAL AND METHODS: A sample of 85 patients diagnosed with superficial bladder tumours was selected to be used in fitting the non-mixture cure model. In order to estimate the parameters of the suggested model, which takes into account the presence of a cure rate, censored data, and covariates, we utilized the maximum likelihood estimation technique using R software version 3.5.7.

    RESULT: Upon conducting a comparison of various parametric models fitted to the data, both with and without considering the cure fraction and without incorporating any predictors, the EE distribution yields the lowest AIC, BIC, and HQIC values among all the distributions considered in this study, (1191.921/1198.502, 1201.692/1203.387, 1195.851/1200.467). Furthermore, when considering a non-mixture cure model utilizing the EE distribution along with covariates, an estimated ratio was obtained between the probabilities of being cured for placebo and thiotepa groups (and its 95% confidence intervals) were 0.76130 (0.13914, 6.81863).

    CONCLUSION: The findings of this study indicate that EE distribution is the optimal selection for determining the duration of survival in individuals diagnosed with bladder cancer.

    The purpose of this study was to evaluate the efficacy and toxicity of radiotherapy concurrently with weekly cisplatin, followed by adjuvant chemotherapy, for the treatment of N2-3 nasopharyngeal cancer (NPC) in Asian countries, especially regions of South and Southeast Asian countries where NPC is endemic. Between 2005 and 2009, 121 patients with NPC (T1-4 N2-3 M0) were registered from Vietnam, Malaysia, Indonesia, Thailand, The Philippines, China and Bangladesh. Patients were treated with 2D radiotherapy concurrently with weekly cisplatin (30 mg/m (2)), followed by adjuvant chemotherapy, consisting of cisplatin (80 mg/m(2) on Day 1) and fluorouracil (800 mg/m(2) on Days 1-5) for 3 cycles. Of the 121 patients, 56 patients (46%) required interruption of RT. The reasons for interruption of RT were acute non-hematological toxicities such as mucositis, pain and dermatitis in 35 patients, hematological toxicities in 11 patients, machine break-down in 3 patients, poor general condition in 2 patients, and others in 8 patients. Of the patients, 93% completed at least 4 cycles of weekly cisplatin during radiotherapy, and 82% completed at least 2 cycles of adjuvant chemotherapy. With a median follow-up time of 46 months for the surviving 77 patients, the 3-year locoregional control, distant metastasis-free survival and overall survival rates were 89%, 74% and 66%, respectively. No treatment-related deaths occurred. Grade 3-4 toxicities of mucositis, nausea/vomiting and leukopenia were observed in 34%, 4% and 4% of the patients, respectively. In conclusion, further improvement in survival and locoregional control is necessary, although our regimen showed acceptable toxicities.

    Malaria, caused by the Plasmodium parasite is still a health problem worldwide due to resistance of the pathogen to current anti-malarials. The search for new anti-malarial agents has become more crucial with the emergence of chloroquine-resistant Plasmodium falciparum strains. Protein kinases such as mitogen-activated protein kinase (MAPK), MAPK kinase, cyclin-dependent kinase (CDK) and glycogen synthase kinase- 3(GSK-3) of parasitic protozoa are potential drug targets. GSK-3 is an enzyme that plays a vital role in multiple cellular processes, and has been linked to pathogenesis of several diseases such as type II diabetes and Alzheimer's disease. In the present study, the antiplasmodial property of LiCl, a known GSK-3 inhibitor, was evaluated in vivo for its antimalarial effect against mice infected with Plasmodium berghei. Infected ICR mice were intraperitoneally administered with LiCl for four consecutive days before (prophylactic test) and after (suppressive test) inoculation of P. berghei-parasitised erythrocytes. Results from the suppressive test (post-infection LiCl treatment) showed inhibition of erythrocytic parasitemia development by 62.06%, 85.67% and 85.18% as compared to nontreated controls for the 100 mg/kg, 300 mg/kg and 600 mg/kg dosages respectively. Both 300 mg/kg and 600 mg/kg LiCl showed similar significant (P<0.05) suppressive values to that obtained with chloroquine-treated mice (86% suppression). The prophylactic test indicated a significantly (P<0.05) high protective effect on mice pre-treated with LiCl with suppression levels relatively comparable to chloroquine (84.07% and 86.26% suppression for the 300 mg/kg and 600 mg/kg LiCl dosages respectively versus 92.86% suppression by chloroquine). In both the suppressive and prophylactic tests, LiCl-treated animals survived longer than their non-treated counterparts. Mortality of the non-treated mice was 100% within 6 to 7 days of parasite inoculation whereas mice administered with LiCl survived beyond 9 days. Healthy non-infected mice administered with 600 mg/ kg LiCl for four consecutive days also showed decreased mortality compared to animals receiving lower doses of LiCl; three of the seven mice intraperitoneally injected with the former dose of LiCl did not survive more than 24 h after administration of LiCl whereas animals given the lower LiCl doses survived beyond four days of LiCl administration. To date, no direct evidence of anti-malarial activity in vivo or in vitro has been reported for LiCl. Evidence of anti-plasmodial activity of lithium in a mouse infection model is presented in this study.

    Two performance (efficacy and attractiveness) comparisons of neonicotinoid baits QuickBayt® (imidacloprid) and Agita® (thiamethoxam) against filth flies were conducted under field conditions to determine suitability for use outdoors. The first experiment compared bait performance and the second compared effects of different applications on QuickBayt® performance. Applications compared were: (i) scattered in petri dish (SPD); (ii) wet-down in petri dish (WPD); (iii) scattered on cardboard (SCB) and (iv) painted on cardboards (PCB). Efficacy and attractiveness were assessed based on knockdown percentage (KD%) and number of flies feeding on baits, respectively. The KD% of QuickBayt® (34% ± 3.0%) was not significantly higher than Agita® (29% ± 1.3%) (t-test, P>0.05). Agita® (101 ± 5.7 flies) was significantly more attractive to flies than QuickBayt® (76 ± 4.8 flies) and the sugar solution (49 ± 7.2) (one-way ANOVA, P<0.05). The PCB and SCB applications were significantly more attractive to filth flies than WPD and SPD (One-way ANOVA, P<0.05), however differences in KD% were not significantly different (One-way ANOVA, P>0.05). The two baits provided the same level of efficacy in a wide-open area against filth flies of various species. QuickBayt® was more versatile; efficacy was not significantly affected by different applications. Surface area and moisture affects attractiveness of the bait.

    Introduction: Diabetes Mellitus is a chronic disease and major cause of chronic renal disease. Chronic renal disease can be prevented if known risk factors were been early detected. Albuminuria is the earliest clinical evidence of chronic renal disease. Objectives of this study is to identify the incidence of albuminuria and relationship between albuminuria with socio demographic and clinical factors such as blood sugar control, blood pressure control, excessive body mass index and hypercholesterolemia.
    Methodology: Data been collected from patient’s record that been regularly follow up at Primary Healthcare Clinics in Negeri Sembilan. Duration of study follow up was from the date of they been diagnosed of Diabetes Mellitus Type 2 until detection of albuminuria or 1st July 2007,end date of data collection then survival analysis been done.
    Result: Majority of study population was female 60.9% and Malay 69.7%. Mean age was 59.9 ± 10.7 and duration having Diabetes Mellitus was 7.0 ± 6.3 years. Only 22% achieved optimum glucose (HbA1c < 6.5%), controlled blood preassure 130/80 mmHg 42.3%, level of cholesterol <4.5 mmol/L only 22.7 %, 11.4% of patients having ideal body weight < 23 kg/m2. The incidence of Diabetes Mellitus Type 2 was 24.4 cases per 1000 population. The median of follow up duration was 22 years; with minimum follow up was 7 months and maximum 42 years. Survival analysis showed that the median of free albuminuria among cases was 22 years (CI 95%:16.5 – 27.4). The log rank test showed no significant relationship between high blood pressure, excessive body mass index and hypercholesterolemia with albuminuria. This study noted that the occurrence of albuminuria seems to be higher among those were hypertensive (26.6%), and excessive body mass index (24.7%).
    Conclusion: Percentage of Diabetes Mellitus Type 2 patient that achieved optimum clinical target still very low. Early detection of albuminuria is very important as preventive measure of diabetes nephropathy. Good blood pressure control and ideal body weight also prevent of occurring diabetes nephropathy complication.

    BACKGROUND: Many prognostic factors have been reported for the outcomes of biliary atresia (BA) patients after Kasai procedure, however, it still shows a conflicting result. Our study was to determine the impact of total bilirubin postoperative day-7 and pre-operative ratio (TB7/TB0), gammaglutamyl transferase post-operative day-7 and pre-operative ratio (GGT7/GGT0), and alanine transaminase post-operative day-7 and pre-operative ratio (ALT7/ALT0) on the survival of BA patients following Kasai surgery.

    METHODS: We reviewed the medical records of BA patients who underwent Kasai procedure at the Dr. Sardjito Hospital, Indonesia from August 2012 to December 2018. The cut-off values of TB7/TB0, GGT7/GGT0, and ALT7/ALT0 for prediction of patients' survival were determined by receiver operating characteristics (ROC) curves. Log-rank tests were utilised to test the association between cut-off values and overall survival.

    RESULTS: In all 46 BA patients (23 males and 23 females) after Kasai procedure were included, consisting of one type 1, 17 type 2A, seven type 2B, and 21 type 3. The cut-off values of TB7/TB0, ALT7/ALT0 and GGT7/GGT0 for overall survival was 0.455 (sensitivity 87.5%, specificity 22.7%, area under curve (AUC) 0.59; 95% Confidence Interval (95%CI): 0.42, 0.75), 0.481 (sensitivity 87.5%, specificity 18.2%, AUC 0.49; 95%CI: 0.31, 0.65), and and 0.31 (sensitivity 79.2%, specificity 9.1%, AUC 0.34; 95%CI: 0.18, 0.50), respectively. However, these cut-off values were not significantly associated with overall survival, with p-values of 0.18, 0.49, and 0.56, respectively.

    CONCLUSION: The TB7/TB0, ALT7/ALT0, and GGT7/GGT0 might not predict the overall survival of BA patients after Kasai procedure. Further multicentre studies with a larger sample size is needed to clarify our findings.

    The demands for timely catheter insertion have spurred the growth of peritoneoscopic catheter insertion program by nephrologists in Malaysia. We performed a multicenter analysis to study its impact on the growth of peritoneal dialysis (PD) population. Data were collected retrospectively from five centers at the point of program initiation until December 2009. In Center 1, with this program, PD population continued to grow from 25 patients in 2006 to 120 in 2009. In center 2, the program began in 2005, but comprised only 28.6% of total insertions. From 2007 onwards, nephrologists had overtaken the surgeon, inserting from 85% to 97% of the total insertions. In center 3, with the program at its infancy, a modest growth in its PD population was shown. In center 4, nephrologists maintained an annual average of 41.8% of total catheter insertions, and thus maintaining a stable PD population. In center 5, surgeon-assisted PD catheter insertions helped to maintain the growth of its PD, seeing lesser impact from this program. Subanalysis showed that 1-year catheter survival in Center 1 was 85.4%. This study on PD catheter insertion program by nephrologists showed the greatest impact on new center and center experiencing suboptimal catheter insertions by traditional providers.

    Mutual interactions, including reciprocal food sharing and grooming between chlorantraniliprole- and fipronil-treated, and untreated Asian subterranean termites, Coptotermes gestroi (Wasmann), were examined using rubidium as a tracer. Two questions were addressed in this study: (1) After insecticide treatment, does the mutual interaction between termiticide-treated termites and untreated nestmates increase? (2) Does the nutritional status of both termiticide-treated termites and untreated nestmates affect the mutual interaction?
