Abstract
Noncompliance with therapy is a big obstacle to successful therapy. We aimed to evaluate the prevalence and risk factors affecting the compliance of pediatric cancer patients with therapy in a tertiary care center far away from the capital in a lower-middle income country (LMIC). A retrospective cohort study of reports of all pediatric cancer patients who were diagnosed and started treatment between 2006 and 2010 at South Egypt Cancer Institute (SECI) was done. The following data were collected: Age, sex, diagnosis, compliance with therapy, and data on potential risk factors that might affect compliance, including time duration of travel from the patient's home to SECI, time lag between the first symptom until the first visit to SECI and until the start of treatment, results of reevaluation after the initial course of therapy, and therapy-related severe adverse events. Noncompliance with therapy was defined as when patients missed their determined therapy appointment for one week or more or abandoned therapy. This study included 510 patients. Eighty-three (16.3%) were non-compliant, as forty patients missed their therapy appointment (7.8%), and 43 abandoned further therapy (8.4%). Noncompliance was found to be more prevalent among patients with solid tumors. Non-compliant patients suffered a significantly higher relapse rate (47.7% vs. 11.2% in compliant patients, p < .001). Unfortunately, 75% of the abandoned patients who returned for further therapy suffered a relapse. Noncompliance with treatment is still a big problem facing cancer management in LMICs.

Abstract
AIMS For patients with locally advanced primary/recurrent breast cancer, radiotherapy is an effective treatment for locoregional control. 36 Gy in 6 Gy once-weekly fractions is a commonly used schedule, but there are no data comparing local control and toxicity between 36 Gy delivered once-weekly versus accelerated schedules of multiple 6 Gy fractions per week. This retrospective study compared local control rates and acute and late toxicity in patients undergoing 30-36 Gy in 6 Gy fractions over 6 weeks versus more accelerated schedules over 2-3 weeks for an unresected breast cancer. MATERIALS AND METHODS Patients who received 30-36 Gy in 6 Gy fractions to an unresected breast cancer ± involved lymph nodes between December 2011 and August 2020 were identified. Patients were grouped into once-weekly versus accelerated fractionation schedules. Response rates, local control and toxicity data were analysed. RESULTS In total, 109 patients were identified. The median follow-up duration was 46 months. Forty-seven patients (43%) received once-weekly fractions and 62 patients (57%) received accelerated fractionation schedules. There were no significant differences in baseline tumour characteristics between the groups. Eighty-seven per cent of patients had an objective (complete or partial) response (81% in the once-weekly group; 91% in the accelerated group). The median time to local progression was 23.5 months overall (95% confidence interval 17.8-29.2); 23.5 months (95% confidence interval 18.8-28.1) in the once-weekly group and 19.0 months (95% confidence interval 7.0-31.1) in the accelerated group (P = 0.99). Acute toxicity of any grade occurred in 75% of patients (76% in the once-weekly group; 74% in the accelerated group) and grade 3 toxicity occurred in 7% of patients (7% in the once-weekly group; 8% in the accelerated group). There were no associations between the groups and acute or late toxicity grade (P = 0.78 and P = 0.26, respectively), although one grade 4 late toxicity (skin radionecrosis) occurred in a patient who received five fractions a week and therefore this regimen is not recommended. Study limitations included a lack of statistical power analysis, the necessary grouping of all accelerated patients for analysis and a high rate of censored data. CONCLUSION There were no apparent differences in response rate, time to local progression or toxicity between patients who received 30-36 Gy in 6 Gy fractions once-weekly compared with twice-weekly as palliative treatment for locally advanced breast cancer. This regimen appears to be a safe alternative and may be preferred by patients.

Abstract
BACKGROUND Echinococcosis is a neglected zoonosis of increasing public health concern worldwide. According to the World Health Organization, 19,300 lives and 871,000 disability-adjusted life-years are lost globally each year because of cystic echinococcosis. Annual costs associated with cystic echinococcosis were estimated at US$ 3 billion because of treatment of cases and losses in the livestock industry. METHODS We performed the random-effects model of meta-analysis using 51-year (1970-2021) data available from AJOL, Google Scholar, PubMed, Science Direct, Scopus and Web of Science. We also applied the Joanna Briggs Institute critical appraisal instrument for studies reporting prevalence data, the Cochran's Q-test, Egger's regression test and the single study deletion technique to respectively examine within-study bias, heterogeneity, across-study bias and sensitivity. RESULTS Thirty-nine eligible studies on human cystic echinococcosis (HCE) from 13 countries across the five African sub-regions showed an overall prevalence of 1.7% (95% CI 1.1, 2.6) with a statistically significant (P < 0.001) sub-group range of 0.0% (95% CI 0.0, 14.1) to 11.0% (95% CI 7.6, 15.7). Highest prevalences were observed in Eastern Africa (2.7%; 95% CI 1.4, 5.4) by sub-region and Sudan (49.6%; 95% 41.2, 58.1) by country. Another set of 42 studies on Echinococcus granulosus infections (EGI) in dogs from 14 countries across the five African sub-regions revealed an overall prevalence of 16.9% (95% CI 12.7, 22.3) with a significant (P < 0.001) variation of 0.4 (95% CI 0.0, 5.9) to 35.8% (95% CI 25.4, 47.8) across sub-groups. Highest prevalences of E. granulosus were observed in North Africa (25.6%; 95% CI 20.4, 31.6) by sub-region and Libya (9.2%; 95% CI 5.7, 13.9) by country. CONCLUSION Human cystic echinococcosis and EGI are respectively prevalent among Africans and African dogs. We recommend a holistic control approach that targets humans, livestock, dogs and the environment, which all play roles in disease transmission. This approach should involve strategic use of anthelminthics in animals, standardized veterinary meat inspection in abattoirs, control of stray dogs to reduce environmental contamination and proper environmental sanitation. Mass screening of humans in hyper-endemic regions will also encourage early detection and treatment.

Abstract
The use of shear-stud in composite slab (CS) construction can significantly enhances its longitudinal shear capacity. However, the strength capacity determination of such complex construction is still marred with the capital-intensive challenge resulting from the complex laboratory procedures for establishing its longitudinal shear capacity. To address this challenge, this article develops a simplified numerical function for determining longitudinal shear capacity for CS with shear stud. This study considers slope-intercept method for the longitudinal shear estimate and the adaptation of rational approach in developing the performance function. Furthermore, limit state function was from the use of shear capacity violation that considers experimental failure load (FL) value and design load estimated form the shear contributions. The resulting outputs from the rational analysis facilitated the formulation of numerical function for the determination of FL in a more simplified form. The developed FL algorithm exhibits strong performance in determining the alternate CS failure load though there is stillroom for further improvement especially if span length would be taken into consideration. Further development that incorporates span length might give much favorable result in determining CS strength especially when considering slope-intercept method

Abstract
Microalgae have the ability to grow in wastewater, remove heavy metal ions and pollutants, and can be used to produce renewable energy alternatives such as biofuels, biogas, biomethane and biohydrogen. Algae can also produce high-value non-energy pigments such as chlorophylls and carotenoids that are used in feeds, colorants, textiles, nutraceutical and pharmaceutical industries. Methanol extraction method was employed to extract the pigments from microalgal specie Chlorella vulgaris spectrophotometrically after bioremediation of synthetic tannery wastewater (STWW) in stirred-tank photobioreactors (STPBRs) operated at about 580 μmol.m-2.s-1 and 100 rpm for 12:12 light-dark cycles. The maximum Chl a, Chl b, total carotenoids and total pigments were determined to be 35.5091, 8.6315, 1.9521 and 41.850 μg/L, respectively and highest content increment of 66.91, 66.97, 69.11 and 69.38% in reactor A, B, C and D, respectively, was achieved during the bioremediation process.

Abstract
Toxoplasmosis is caused by an obligate intracellular protozoan parasite; Toxoplasma gondii, which is one of the most important zoonotic parasite worldwide. In dogs, the sexual reproductive cycle of T. gondii is lacking, and the animals are not widely consumed as food, but they are vital in the mechanical transmission of the parasite. However, there is no present data on the exposure of stray dogs to T. gondii in Malaysia. The objective of this serological survey was to determine the prevalence of T. gondii antibodies (IgG) and associated factors in stray dogs in East and West Malaysia. Antibodies to T. gondii were determined in serum samples from 222 stray dogs from 6 different states in East and West Malaysia (Peninsular Malaysia) using an Indirect ELISA. The seroprevalence for T. gondii was 23.4% (Confidence interval: CI 17.8-29.2%). Stray dogs from Selangor and Kuala Lumpur had the highest seroprevalence (32.4%; CI 13.2-45.5%) and lowest in those from Penang and Kedah (12.5%; CI 1.3-23.5%). Gender and breed were not associated with T. gondii seropositivity. However, adult dogs were more likely to be seropositive for T. gondii (OR=2.89; CI 1.1-7.7) compared with younger dogs. These results revealed that T. gondii is prevalent in stray dogs in the studied areas in Malaysia, and indicative of the level of environmental contamination of this parasite especially in urban areas.

Abstract
BACKGROUND The primary outcome of this study is to investigate the association between the cardiopulmonary exercise testing (CPET) variables: anaerobic threshold (AT), peak oxygen uptake (VO2 peak), peak work rate (WR), ventilatory equivalence of CO2 (VE/VCO2) at the anaerobic threshold (AT) with frailty, measured by the clinical frailty scale (CFS) in patients planned to undergo major abdominal cancer surgery. The secondary outcome is to compare the CPET variables (VO2 peak, peak WR, VE/VCO2 at AT) with frailty measured by the CFS in predicting postoperative surgical morbidity in patients following major abdominal cancer surgery. METHODS This study was a single-centre prospective cohort analysis of consecutive adult patients undergoing CPET and CFS scoring as part of their pre-operative work-up for major abdominal cancer surgery. RESULTS A total of n = 317 patients underwent CPET and CFS assessment ahead of planned abdominal oncological surgery. Negative correlations were observed between the CPET variables: AT - 0.42 p < 0.01; VO2 peak - 0.53 p < 0.01; peak WR - 0.54 p < 0.01 with CFS scores and a positive correlation between CFS scores and VE/VCO2 0.29 p < 0.01. Only CFS remained statistically significant in a multivariate model OR 2.11 (1.42-3.15) 95% CI associated with Clavien-Dindo (CD) ≥ 1 defined morbidity including the significant univariate variables (VO2 peak, peak WR and CFS scores). No variables were associated with CD ≥ 3 morbidity. CONCLUSIONS In patients scheduled to have major abdominal cancer surgery there was a weak association between poor performance on CPET and increasing frailty measured by the CFS. The CFS score unlike CPET was associated with all post-operative morbidity, but not major complications alone, in these patients. This suggests that CFS may be used as a less expensive alternative to CPET for predicting any postoperative morbidity in major abdominal cancer surgery.

Abstract
Abstract
Background
The presence and extent of residual invasive cancer after neoadjuvant treatment (NACT) is a strong prognostic factor for risk of recurrence, especially in triple-negative (TN) and human epidermal growth factor receptor 2-positive (HER2+) breast cancer (BC). Recent advances in the standard-of-care NACT improved pathological complete response (pCR) rates in published clinical trials.
We evaluated the pCR rates, defined as ypT0-is ypN0, in our real-world BC population and in estrogen receptor-positive [ER+] HER2-, HER2+ and TN subgroups and their association with tumour, patients' characteristics and disease-free survival (DFS).
Methods
We retrospectively identified early BC patients receiving NACT between January 2013 and December 2017. Demographics, patient and disease characteristics, pathological responses, toxicities, dose delays and reductions were recorded. Simple statistics, Fisher's exact test, chi-squared method and Cox regression were used as appropriate.
Results
794 patients identified had median age of 50 years (range 24-87) and 93.9% (745 patients) ECOG performance status (PS) 0. 3.0% (24) had clinical stage I disease, 68.0% (540) stage II and 29.0% (230) stage III. 71.0% (564) had grade 3 disease and 91.8% (729) ductal histology. 33.7% (257) had ER+/HER2-, 25.8% (205) had TN and 38.0% (301) HER2+ disease. Overall, 6.8% (54) patients received platinum. 36.6% (291) patients had dose reductions and 24.3% (193) dose delays. Along with NACT, 51.6% (147) of the HER2+ patients received Trastuzumab and Pertuzumab and 48.4% (138) Trastuzumab alone.
pCR rate was 33.1% in the overall population and significantly different in ER+/HER2-, HER2+ and TN subgroups (12.84% versus 52.0% versus 28.43% respectively, p<0.001). pCR was influenced by grade (1: 0%; 2: 24.3%; 3: 36.1%, p 0.005) and histology (ductal: 34.2%; lobular: 10.0%; mixed 25.0%; p 0.01). In the HER2+ subgroup, there was a trend for improved pCR rates for patients receiving Pertuzumab and Trastuzumab (57.0%) versus Trastuzumab alone (51.0%). No statistically significant differences were seen based on patients' characteristics including age and PS or in case of treatment dose reductions and delays. Early discontinuation of NACT was associated with lower pCR rates (20.5% vs 36.29%, p <0.001).
Of interest, pCR rates remained consistent across the period 2013-2017 in the overall population. We observed a trend for improved pCR in the HER2+ (2013: 47.5%; 2014: 44.4%; 2015: 66.7%; 2016: 51.0%; 2017: 51.4%) and TN cohorts (2013: 23.5%; 2014: 25.0%; 2015: 25.0%; 2016: 33.3%; 2017: 34.1%) but not in the ER+/HER2- group.
Median DFS was 83.8 months (95% CI 62.0-NR) in the overall population. Although not reached in the TN cohort, median DFS was different according to disease subgroups (HER2+: 83.78 months; TN: NR; ER+/HER2-: 62.0 months, p <0.0001).
Conclusions
In our analysis pCR rates are consistent with data published in literature and higher in HER2+ and TN disease. The impact of new agents had a relatively low impact on pCR rates in our overall population over the last 5 years, although they produced gradual improvements in the HER2+ and TN subgroups.

Abstract
Objectives: This systematic review evaluated the accuracy of triaxial and omnidirectional accelerometers for measuring physical activity and sedentary behavior in children. Design: Systematic review of the literature. Methods: We comprehensively searched several databases for studies published from January 1996 through June 2018 that reported diagnostic accuracy measures in children and adolescents (age 3-18 years) and compared accelerometers with energy expenditure using indirect calorimetry. Results: We included 11 studies that enrolled 570 participants. All studies used indirect calorimetry as the reference standard. Across the studies, median sensitivity ranged from 46% to 96% and median specificity ranged from 71% to 96%. Median area under the curve ranged from 69% to 98%. Conclusions: Accuracy measures were greatest when detecting sedentary behavior and lowest when detecting light physical activity. Accuracy was higher when the accelerometer was placed on the hip compared with the wrist. The current evidence suggests that triaxial and omnidirectional accelerometers are accurate in measuring sedentary behavior and physical activity levels in children.

Abstract
Background Society of Surgical Oncology and American Society for Radiation Oncology guidelines define clear margins in breast-conserving therapy (BCT) as 'no ink on tumour', in contrast to the attainment of margins of at least 1 mm widely practised in the UK. The primary aim of this study was to explore clinical, surgical and tumour-related factors associated with local recurrence after BCT, with a secondary aim of assessing the impact of margin re-excision on the risk of local recurrence. Methods Patient demographics, surgical details, tumour characteristics and local recurrence were recorded for consecutive women with BCT undergoing surgery between January 1997 and January 2007. Margins were defined as clear (greater than 1 mm), close (less than 1 mm but no ink on tumour), reaches (ink on tumour) and clear after re-excision. Results A total of 1045 women of median age 54 (range 18-86) years were studied. Median follow-up was 89 (range 4-196) months. Local recurrence occurred in 52 patients (5·0 per cent). Ink on tumour was associated with local recurrence (hazard ratio (HR) 4·86, 95 per cent c.i. 1·49 to 15·79; P = 0·009). Risk of local recurrence was the same for close and clear margins (HR 1·03, 0·40 to 2·62; P = 0·954). In women with involved margins, re-excision was still associated with an increased local recurrence risk (HR 2·50, 1·32 to 4·72; P = 0·005). Oestrogen receptor negativity increased risk (HR 2·28, 1·28 to 4·06; P = 0·005). Conclusion Adequately excised margins, even when under 1 mm, provide equivalent outcomes to wider margins in BCT. Achieving complete excision at primary surgery achieves the lowest rates of local recurrence.

Abstract
BACKGROUND Patients with oesophago-gastric (OG) cancer may be at risk of malnutrition, troublesome gastrointestinal symptoms (GI) and reduced dietary intake in view of the tumour location and multimodality curative treatment approach. Longitudinal research is lacking. The present study aimed to assess (i) nutritional status and how it evolved over the first year; (ii) the association between nutritional status scores and GI symptom scores; and (iii) the nutrient and food group intake pattern. METHODS This was a prospective, observational study of patients with an OG lesion planned for radical treatment, with assessment at diagnosis, 3 months and 12 months after the start of treatment. Nutritional assessment was performed using the Patient-Generated Subjective Global Assessment, GI symptoms measured using the modified Gastrointestinal Symptom Rating Scale and dietary intake assessed using a semi-quantitative food frequency approach. RESULTS Eighty patients (61 males, 19 females; aged 46-89 years) were recruited. At baseline, 3 (n = 68) and 12 months (n = 57), 61%, 62% and 60%, respectively, were moderately/severely malnourished. Higher symptom burden was associated with poorer nutritional status at baseline (r = 0.55, P < 0.001), 3 months (r = 0.51, P < 0.001) and 12 months (r = 0.42, P = 0.001). At each respective time point, 37%, 38% and 42% were meeting their estimated average requirement for energy. No change in mean (SD) intake of energy, fibre, nutrient and food groups was observed over time. CONCLUSIONS Patients with OG cancer have progressive weight loss, with malnutrition present over the majority of the 12-month study period. Optimising nutritional status and symptom management throughout the treatment pathway should be a clinical priority.

Abstract
Abstract
Background: Breast cancer (BC) is one of the most common malignancies affecting women. Brain metastatses (BM) are frequently seen in BC, and can have devastating consequences with significant associated morbidity and mortality. Whole brain radiotherapy (WBRT) is commonly used to treat BM, with variable use of stereotactic radiotherapy (SRT). This study reports on the outcomes of BC patients with BM who received central nervous system (CNS) radiotherapy over a 17-year period at the Royal Marsden Hospital (RMH).
Methods: We included all BC patients who had WBRT with or without SRT for intra-parenchymal BM secondary to BC at RMH between 2000 and 2016 inclusive. Instances of meningeal involvement were excluded from analysis. Data collected included age, histological subtype, tumor grade, stage at original BC presentation, receptor status, date of BM diagnosis, number of metastases, size of largest BM, Eastern Cooperative Oncology Group (ECOG) score, presence of extra-cranial metastases (ECM), neurosurgery (NS) and stereotactic radiotherapy (SRT) details, and date of last follow up or death. Univariate and multivariate analyses were performed to analyze the effect of each variable on overall survival (OS) from date of BM.
Results: A total of 426 patients were included with a median age of 54 years at BM diagnosis and a median time to BM from BC diagnosis of 43 months. At diagnosis, 94% had invasive ductal carcinoma (IDC) and 70% had Grade 3 disease. Stage IV disease at original BC presentation was seen in 18% of patients. Estrogen receptor (ER+) was positive in 57% (n = 236), progesterone receptor (PR+) in 44% (n = 147), and HER2 (HER2+) in 44% (n = 166). Twenty-two percent (n = 89) were triple negative (TN). Median number of BM was 4 (range 1 – 205) and 20% (n = 72) of patients had only 1 BM. Average size of the largest lesion was 26 mm (range 1 – 75). The ECOG score was 0 – 1 in 61% of patients. Ten percent of patients (n = 44) underwent SRT and 10% (n = 43) underwent NS. Three hundred and eighty patients had died at the time of analysis. Median OS from date of BM was 6.4 months. On univariate analysis, age < 60 years at BC diagnosis (8.1 vs. 4.0 months, p = 0.0007) and BM diagnosis (8.0 vs. 5.6 months, p = 0.03), ECOG status 0-1 (9.6 vs. 4.0 months, p = <0.0001), ER+ (8.0 vs. 6.0 months, p = 0.0007), PR+ (7.6 vs. 6.9 months, p = 0.04), HER2+ (10.5 vs. 5.6 months, p < 0 .0001), SRT (20.3 vs. 5.9 months, p < 0.0001) and NS (20.3 vs. 6.2 months, p < 0.0001) significantly predicted for improved OS. Triple negative status predicted for worse survival (5.6 months vs. 8.1 months, p < 0.0001). On multivariate analysis, ECOG status, ER+, HER2+, treatment with SRT and NS were independent predictors for OS.
Conclusions: This study confirms substantial heterogeneity of prognosis in patients with BM from BC, with significantly improved survival in patients selected for SRT or surgery. Further studies are required to optimize the role of CNS radiotherapy techniques such as SRT and hippocampal sparing WBRT in patients with a favorable prognosis.

Abstract
This study investigated canine vector borne diseases (CVBDs) of zoonotic significance in three major shelters in Peninsular Malaysia in order to highlight the importance of shelter management in diseases prevention. Since crowded housing has the potential to bring vectors and infected dogs into close proximity, the prevalence of CVBDs infection is always higher in sheltered dogs in comparison to pet dogs. Serum was collected from 90 adult dogs (30 from each shelter) from three shelters in different regions of Peninsular Malaysia (Shelter A, B and C). The prevalence of Dirofilaria immitis, Ehrlichia canis, E. ewingii, Anaplasma phagocytophilum, A. platys and Borrelia burgdorferi in dogs residing in three shelters with different management protocols was investigated by using rapid clinical test kits, SNAP® 4Dx® Plus (IDEXX Laboratories, Westbrook, ME). The most common pathogen detected was Ehrlichia spp. (55.6%, 50 out of 90 dogs), followed by Anaplasma spp. (16.7%; 15 out of 90 dogs). Dirofilaria immitis could only be detected in one of the shelters (10.0%; nine out of 90 dogs). No evidence of B. burgdorferi was detected in all three shelters. Forty one out of 90 dogs (45.6%) were infected with at least one pathogen meanwhile 14 out of 90 dogs (15.6%) were infected with more than one pathogen. It is of crucial importance to practice preventive measures during the admission of the new animals into the facilities. Occasional treatment of the dogs (as practiced in Shelter B) was not effective when compared to scheduled preventive measures. Future studies should emphasize the isolation and additional molecular characterization of vector borne pathogens in Peninsular Malaysia. In addition, studies that define the tick species that infest dogs in this region would help to elucidate their role as vectors for disease transmission.

Abstract
OBJECTIVE To evaluate Telephone-Delivered Cognitive Behavioural Therapy (T-CBT) compared to CBT face to face treatment as usual (TAU-CBT), in cancer patients with high psychological needs, in terms of mental health and coping. METHOD A prospective randomised equivalence trial with Patient Reported Outcome (PRO's), measured pre- and post-therapy including; Hospital Anxiety and Depression Scale (HADS), Mental Adjustment to Cancer Scale: Helpless/Hopeless subscale only (MAC H/H), Checklist of Cancer Concerns (CLCC) and the Cancer Coping Questionnaire (CCQ). A study-specific Service Evaluation Questionnaire (SEQ) was include. RESULTS Assessment of change scores, in n = 118 randomised patients referred for psychological care, indicate significant improvements (P < 0.01 or greater) for both therapy groups pre- and post-therapy in HADS anxiety, depression and total scores and cancer concerns (CLCC). Overall, for the groups combined, there is a significant shift towards reduction of CCQ stress (P = 0.028) and worry (P = 0.003) post-therapy when compared to baseline levels. Median number of therapy sessions was four. For cancer coping (CCQ) and for Mental Adjustment to Cancer (MAC) there were significant change scores only for Positive Focus and Helpless/hopeless scores respectively, in the TAU-CBT group. Although equivalence was not observed, the data demonstrate that T-CBT was non-inferior to TAU-CBT. CONCLUSIONS Delivery of CBT to patients with clinician identified high need can be offered according to patient choice without loss of mental health benefit. Both TAU-CBT and T-CBT are effective at reducing mental health problems on the specific outcome measures.

Abstract
Aim: Gastrointestinal helminthosis is a global problem in small ruminant production. Most parasites have developed resistance to commonly available anthelminthic compounds, and there is currently an increasing need for new compounds with more efficacies. This study evaluated the in vitro effects of ethanolic extract of Curcuma longa (EECL) as a biological nematicide against third stage Haemonchus larvae (L3) isolated from sheep. Materials and Methods: Haemonchus L3 were cultured and harvested from the feces of naturally infected sheep. EECL was prepared and three concentrations; 50, 100, and 200 mg/mL were tested for their efficacies on Haemonchus L3. Levamisole at concentration 1.5 and 3 mg/mL were used as positive controls. Results: EECL showed anthelmintic activity in a dose-dependent manner with 78% worm mortality within 24 h of exposure at the highest dose rate of 200 mg/mL. There was a 100% worm mortality rate after 2 h of levamisole (3 mg/mL) admisntration. However, there was a comparable larvicidal effect between when levamisole (1.5 mg/mL) and EECL (200 mg) were administered. Conclusion: The study shows that EECL does exhibit good anthelmintic properties at 200 mg/mL which is comparable with levamisole at 1.5 mg/mL.

Abstract
BACKGROUND Trastuzumab has changed the natural history of metastatic HER2 positive breast cancer. Some patients remain well and in remission for many years. There is currently no established duration after which trastuzumab in the advanced setting can be safely discontinued. This study aims to evaluate long-term efficacy and cardiac safety of trastuzumab when used as first-line treatment for patients with metastatic HER2 positive breast cancer. PATIENT AND METHODS We retrospectively identified 215 patients with HER2 positive, locally advanced or metastatic breast cancer who commenced first line trastuzumab-containing therapy for metastatic disease between 2001 and 2010 at The Royal Marsden Hospital. RESULTS The median progression free survival for all patients was 12 months (95%CI: 10.3-14.6 months); 103 (48%) patients remained in remission beyond one year, 59 (27%) beyond two years and 25 (12%) beyond five years. The median overall survival was 2.6 years (95% confidence interval (CI): 2.2-3.3). The objective response rate (ORR) was 65% with 17 (8%) complete responses and 120 (57%) partial responses. Trastuzumab was well tolerated. Twenty eight (13%) patients recorded any grade of left ventricular dysfunction. There was no significant difference in cardiac toxicity between those patients on less than or more than one year of trastuzumab. CONCLUSION Trastuzumab is associated with long-term remissions in a significant proportion of patients with metastatic HER2 positive disease when used in the first-line advanced setting.

Abstract
BACKGROUND Radiotherapy for muscle invasive bladder cancer (MIBC) aims to offer organ preservation without oncological compromise. Neo-adjuvant chemotherapy provides survival advantage; response may guide patient selection for bladder preservation and identify those most likely to have favourable result with radiotherapy. METHODS Ninety-four successive patients with T2-T4aN0M0 bladder cancer treated between January 2000 and June 2011 were analysed at the Royal Marsden Hospital. Patients received platinum-based chemotherapy following transurethral resection of bladder tumour; repeat cystoscopy (± biopsy) was performed to guide subsequent management. Responders were treated with radiotherapy. Poor responders were recommended radical cystectomy. Progression-free survival (PFS), disease-specific survival (DSS) and overall survival (OS) were estimated using Kaplan-Meier method; univariate and multivariate analyses were performed using the Cox proportional hazard regression model. RESULTS Response assessment was performed in 89 patients. Seventy-eight (88%) demonstrated response; 53 (60%) achieved complete response (CR); 74 responders had radiotherapy; 4 opted for cystectomy. Eleven (12%) demonstrated poor response, 10 received cystectomy. Median survival for CR was 90 months (95% CI 64.7, 115.9) compared with 16 months (95% CI 5.4, 27.4; P < 0.001) poor responders. On multivariate analysis, only response was associated with significantly improved PFS, OS and DSS. After a median follow-up of 39 months (range 4-127 months), 14 patients (16%) required salvage cystectomy (8 for non-muscle invasive disease, 5 for invasive recurrence, 1 for radiotherapy related toxicity). In all, 82% had an intact bladder at last follow-up after radiotherapy; 67% had an intact bladder at last follow-up or death. Our study is limited by its retrospective nature. CONCLUSIONS Response to neo-adjuvant chemotherapy is a favourable prognostic indicator and can be used to select patients for radiotherapy allowing bladder preservation in >80% of the selected patients.

Abstract
BACKGROUND Breast cancer (BC) is the 2nd commonest cause of brain metastases (BM). This retrospective review investigates the applicability of prognostic scores and highlights different outcomes for patients with HER2 positive compared to triple negative (TN) subtypes. METHODS Two hundred and seventy four patients received whole brain radiotherapy for BC BM (01/2000-12/2011). The primary objective was to determine factors influencing overall survival (OS). All information relevant to primary BC, disease recurrence, treatment, outcome and cause of death (either neurological (NP) or systemic progression (SP)) were collected. Univariate (UV) and multivariate (MV) Cox regression analysis were used. RESULTS One hundred and forty four patients (53%) were ER positive, 104 (38%) HER2 positive and 57 (21%) TN. Median age at BM was 53 (27-81) years and median OS from BM diagnosis 7.3 (5.7-8.9) months. On MV analysis, Her2 status, RPA score, surgery, stereotactic radiotherapy, and absence of TN disease were independent prognostic factor for OS. NP was the cause of death in 69.2% of HER2 positive patients and 17.3% had SP. Of the TN patients, 29.8% had NP and 54.4% SP (p < 0.001). CONCLUSION A consistent OS advantage is noted for HER2 positive BM cases and inclusion of BC subtype in the breast GPA score should improve the prognostic factors' sensitivity. The unique presentations, response to treatment and causes of death for HER2 positive patients means more aggressive focal therapy should be considered and studied in the context of clinical trials. For TN BM patients with poor performance status, best supportive care may be appropriate.

Abstract
A Boer-Kajang cross male goat was presented to the Veterinary Hospital, University Malaysia Kelantan with a history of dysuria, hematuria and restlessness. The goat was intensively managed (confined to the pen) and fed with only palm kernel cake for the last three months. Physical examination revealed that the goat was dull, depressed, having an inflamed penis and prepuce with blood stained urine dripping from the penis. The differential diagnoses were obstructive urolithiasis, urinary tract infection and balanoposthitis. Based on the history, clinical signs, physical examination, urinalysis, ultrasonagraphy and feed analysis, the goat was diagnosed with obstructive urolithiasis and balanoposthitis. Treatment was instituted by amputation of the urethral process and retrograde urohydropulsion to relieve the blockade. Sulfadiazine-trimethoprim (Norodine®24) 15mg/kg, I.M; flunixin meglumine 2.2mg/kg, I.M; vitamin B complex 1ml/10kg, I.M and ammonium chloride 300mg/kg orally were administered. The goat responded well to treatment and was recovering well during a follow up visit.
