    BACKGROUND: Digital mammograms with appropriate image enhancement techniques will improve breast cancer detection, and thus increase the survival rates. The objectives of this study were to systematically review and compare various image enhancement techniques in digital mammograms for breast cancer detection.

    METHODS: A literature search was conducted with the use of three online databases namely, Web of Science, Scopus, and ScienceDirect. Developed keywords strategy was used to include only the relevant articles. A Population Intervention Comparison Outcomes (PICO) strategy was used to develop the inclusion and exclusion criteria. Image quality was analyzed quantitatively based on peak signal-noise-ratio (PSNR), Mean Squared Error (MSE), Absolute Mean Brightness Error (AMBE), Entropy, and Contrast Improvement Index (CII) values.

    RESULTS: Nine studies with four types of image enhancement techniques were included in this study. Two studies used histogram-based, three studies used frequency-based, one study used fuzzy-based and three studies used filter-based. All studies reported PSNR values whilst only four studies reported MSE, AMBE, Entropy and CII values. Filter-based was the highest PSNR values of 78.93, among other types. For MSE, AMBE, Entropy, and CII values, the highest were frequency-based (7.79), fuzzy-based (93.76), filter-based (7.92), and frequency-based (6.54) respectively.

    CONCLUSION: In summary, image quality for each image enhancement technique is varied, especially for breast cancer detection. In this study, the frequency-based of Fast Discrete Curvelet Transform (FDCT) via the UnequiSpaced Fast Fourier Transform (USFFT) shows the most superior among other image enhancement techniques.

    The influence of the cool and warm temperatures on early life development and
    survival of tropical oyster, Crassostrea iredalei was studied. D-hinged larvae (day 1 larvae)
    were reared to three different temperatures (20°C, 27°C, and 34°C) for nine days. Oyster
    larvae reared in temperature 27°C, acted as control (ambient temperature). The highest
    survival rate occurred when the larvae were reared in 20°C and 27°C. Larvae reared at
    34°C exhibited reduced survival but increase in the growth rate. The growth rate in larvae
    reared in high temperature (34°C) was significantly higher compared to larvae reared in
    20°C and 27°C (p

    The serious deterioration of the ecological environment comes from a large number of geological disasters. These disasters were caused by a number of engineering activities. Ecological restoration is an important measure to reduce geological disasters and protect the ecological environment. On the basis of the introduction of cast-in-situ grids technology, external-soil spray seeding technology and vegetation bag technology, according to the ecological restoration experiment of the road slope attach to the Three Gorges Pumped-Storage Power Station in Hohhot, decision analysis of slope ecological restoration is done with AHP. It is shown that in arid and semi-arid area, selection of slope ecological restoration scheme mainly needs considering the ecological effect and stability. The major factor of ecological effects is survival rate of vegetation. The major factor of stability is the stability in a whole. Cast-in-situ grids technology will be the first choice for ecological restoration of road slope in arid and semi-arid area. This study provides reference for decision of the slope ecological restoration in arid and semi-arid region.

    Dialysis adequacy is conventionally quantified as net urea clearance. Single pool (sp) Kt/Vurea remains the best studied measure of dialysis adequacy globally. Other measures such as fluid status control, anemia correction, and mineral metabolism are monitored variably. Increasing use of hemodiafiltration across Europe and many parts of Japan and Australia is predicated on studies showing better patient survival with middle molecule clearance. Apart from local clinical practice guidelines, the income level and public health policy of a country determine quality of dialysis services. Among developed nations, small solute clearance adequacy targets are achieved with high frequency. In the United States, dialysis adequacy target is met by focussing on high blood flow rates and large dialyzer size, sometimes at the cost of session time. In Japan, Australia, and Germany, session length is given importance. Dialysis adequacy reporting is restricted and inconsistent in developing nations. The Gulf Cooperation Council countries, Russia and Malaysia, respectively, are close to achieving dialysis adequacy target (spKt/Vurea ≥1.2) universally in their dialysis populations. Patient-reported outcomes are typically measured only in developed countries. Patient survival on dialysis, partly linked to dialysis adequacy, varies greatly around the world, with Japan having the best survival rates. Until the development of better markers of dialysis adequacy, universal consistency in reporting of conventional parameters with a focus on patient-reported measures should be endeavored.

    Prostate cancer (Pca) is one of the most prevalent health conditions affecting men, particularly older men, and cases have increased in recent years.

    OBJECTIVE: This review examined the survival rate and prognostic factors of patients with Pca in Southeast Asia (SEA).

    METHODS: We conducted a systematic search of three databases (PubMed, Scopus, Web of Science) and a manual search until April 1, 2022. The selected papers were evaluated using the Newcastle-Ottawa Quality Assessment Form for Cohort Studies. The review protocol was registered with PROSPERO (CRD42022326521). Pooled prevalence rates were calculated using the programme R version 4.2.1. Heterogeneity was assessed using the I2 statistic and p-value. A narrative approach was used to describe prognostic factors. Studies were selected and finalised based on the review question. The quality of the included studies was assessed.

    RESULTS: A total of 11 studies were included in this review. The 1-, 3-, 5- and 10-year survival rates of SEA Pca cases were 80.8%, 51.9%, 66.1% (range 32.1-100) and 78% (range 55.9-100), respectively. Prognostic factors for Pca were discussed in terms of sociodemographic, disease-related and treatment-related aspects. The predictors of significantly lower survival were age more than 75 years, cancer detected during transurethral resection of the prostate, Gleason score more or equal to eight, high-risk group, metastases and no adjuvant radiotherapy. A meta-analysis on the pooled HR of prostate cancer could not be performed due to the heterogeneity of prognostic factors. The pooled prevalence of localised and metastatic prostate cancer in SEA countries was 39% 95% CI [20-62] and 40% 95% CI [28-53], respectively.

    CONCLUSION: The survival rate in SEA countries can be determined by prognostic factors, which can be divided into sociodemographic, disease-related and treatment-related factors. Therefore, further studies are needed to improve the understanding and treatment of Pca in the region SEA.

    Endometrial (ECa), ovarian (OCa) and cervical (CCa) cancers are among 10 of the most common cancers affecting women worldwide. Cancers are known to cause some proteins to be differentially glycosylated or aberrantly excreted in the urine, which can be used as biomarkers. Since ECa, OCa and CCa are difficult to diagnose at the early stage, the aim of the present study was to identify a panel of new biomarkers for early detection of the cancers using surface-enhanced laser desorption/ionization-time-of-flight (SELDI-TOF) technology. Identification of early biomarkers that are specific and efficient can increase the survival rate of the patients.

    Introduction: High survival rates of dental implants were commonly reported even after 10 years of follow up. Nevertheless, complications and failure may occur and the implant would need to be removed. In recent years, the use of autogenous blood products in dental surgery has increased due to its ability to aid the healing of the soft and hard tissues. Clinical case: The case demonstrated the utilisation of concentrated growth factor (CGF) from the patient’s blood for healing following conservative removal of a failed dental implant. Subsequently, the patient showed satisfactory recovery without any infections and clinical complaints. Conclusion: This explantation procedure, together with the use of CGF, may prevent the normal bone resorption and accelerate soft tissue healing. As it is biological in nature having originated from the patient’s blood, it is more readily accepted by the tissues and the risk of infection is low.

    Tacrolimus, which bonds to an immunophilin, FK506 binding protein (FKBP) has emerged as one of the most widely used immunosuppressant post solid organ transplantation. It offers excellent patient survival rates post-transplantation and a lesser number of acute rejections as compared to cyclosporine. Tacrolimus has a narrow therapeutic window with overexposure leading to acute and chronic forms of nephrotoxicity. Remarkably few data have been published on the overexposure to tacrolimus following mild diarrhoea in post-transplant patients who received treatment with tacrolimus. We observed a post-liver transplant patient with increased trough level of tacrolimus during severe diarrhoea with no complications following a timely adjustment on the dose of tacrolimus.

    Introduction: Kidney transplantation (KT) is the preferred end-stage renal disease (ESRD) treatment because it pro-vides a better survival rate, quality of life as well as a cheaper alternative. However, Malaysia’s KT rates is consis-tently low considering that ESRD rates have been increasing exponentially. With only four hospitals performing KT, there’s a gap to indicate a lack of evaluation in KT system of Malaysia. Qualitative study was undertaken to explore and describe the barriers and solutions improve the rates and service of KT in Malaysia. Methods: Semi-structured interviews adopted as qualitative methodological approach to explore current KT policy and service in Malaysia be-tween March – May 2018 in Kuala Lumpur. Eight key-informants selected using stakeholder analysis and informed consent were obtained. Interviews were digitally audio-recorded, transcribed verbatim and analysed using thematic analysis. Results: Barriers and solutions of Malaysia’s KT are the results of complex interplay of personal, cultural, and environmental factors that can be categorized and described using the five levels of influence conceptualized by the socio-ecological model (SEM). Guidance for developing culturally appropriate and sensitive interventional strategies was elicited from the key informants’ experiences to improve KT rate and services in Malaysia. Conclusion:Malaysia is experiencing very low rate of KT compared to other countries. The use of SEM provided a framework to foster a better understanding of current practice, barriers and solutions to KT in Malaysia. Implications of these find-ings could prompt policy change for better KT service delivery model. Further stakeholder engagement and evalua-tion is required to align best practices to improve KT rates and service in Malaysia that is comparable to high-income countries.

    This study was carried out to determine the physiological changes (survival, growth, molting cycle, sex differentiation, and gill condition) of mud crab, Scylla paramamosain crablet at different water temperatures of 24, 28 and 32 °C, and ambient temperature of 27 to 30 °C. Thermoregulatory behavior, represented by preferred temperature (29.83 ± SD 2.47 °C), critical thermal minimum (17.33 ± SD 0.58 °C), critical thermal maximum (40 ± SD 0.00 °C), and thermal tolerance interval (22.67 ± SD 0.58 °C), were checked for Crablet 1 stage only (with ambient temperature as acclimation temperature).Both low (24 °C) and high (32 °C) temperatures were associated with lower growth performance, and survival rate (p < 0.05), in comparison with both 28 °C and ambient temperature treatments.Male ratio at low temperaturetreatment (24 °C) was higher (80.09 ± SD 18.86%) than for other treatments (p < 0.05), observed as 44.81 ± D 10.50%, 41.94 ± SD 19.44%, and 76.30 ± SD 5.13% for 28 °C, 32 °C and ambient temperature treatments, respectively. However, there was no significant difference observed between 24 °C, 28 °C, and ambient temperature treatments. Anatomical alterations of gill lamellae of S. paramamosain crablet for both 32 °C, and 24 °C treatments, appeared thinner and paler than at both 28 °C, and ambient temperature treatments. Based on this study, temperature of 28 to 30 °C was recommended as the optimal temperature for the long-term nursery phase of S. paramamosain.

    Cyclopoid copepod has a potential as live feed that can provide ornamental fish larvae with energy and essential nutrients, and promote their growth and survival, as well as affect their colouration. However, the nutrition, growth and nutritional requirements of this species are poorly understood. This research focuses on comparing the efficacy of enrichment types on copepods towards the growth rate, survival rate and colouration of Pterophyllum scalare larvae. The enrichment of copepods consists of four enrichment procedures (rice bran, palm kernel cake (PKC),Chlorella and yeast). This study was carried out over 50 days and the growth rate, survival rate and colouration (growth rate, survival rate, SGR and colouration) were used to evaluate the responses of P. scalare larvae towards different enrichment methods. Specific growth rates (8.0161 ± 1.4928 %; P = 0.775) and survival rates (66.667 ± 5.337%; P = 0.815) of fish larvae were found to not be significantly different (P = 0.775, P = 0.815; P >0.05). However, the colouration of the fish larvae was affected by the types of enrichment used (P

    Background: The three-parent assisted reproductive technique may increase oocyte competence.

    Objective: In this case-control study, the suitability of germinal vesicle transfer (GVT), synchronous ooplasmic transfer (sOT), asynchronous ooplasmic transfer using cryopreserved MII oocyte (caOT), and asynchronous ooplasmic transfer using waste MII oocyte (waOT) for maturation of the human-aged non-surrounded nucleolus germinal vesicle-stage (NSN-GV) oocyte were investigated.

    Materials and Methods: NSN-GV oocytes were subjected to four methods: group A (GVT), B (sOT), C (caOT) D (waOT), and E (Control). The fusion rates, MI, MII, ICSI observations and cleavage at 2-cell, 4-cell, and 8-cell stages were compared in the groups.

    Results: In GVT, none of the oocytes fused. In sOT, all oocytes fused, 20 achieved the MI, 14 progressed to MII, 8 fertilized, 6 cleaved and 5, 4, and 3 achieved the 2-cells, 4-cells and 8-cells, respectively. In caOT, all oocytes fused and achieved the MI, 8 progressed to MII and fertilized, 6 cleaved and 6, 5, and 5 achieved the 2-cells, 4-cells, and 8-cells respectively. In waOT, all oocytes fused, 5 and 3 progressed to MI and MII, respectively, but only one fertilized, cleaved and reached a 4-cells stage. In group E, 6 and 2 oocytes progressed to MI and MII, respectively, and only one fertilized but arrested at the zygote stage. caOT had the highest survival rate when compared to sOT (p = 0.04), waOT (p = 0.002), and control (p = 0.001).

    Conclusion: The caOT method was beneficial over sOT, waOT, and GVT in supplementing the developmental capacity of human-aged NSN-GV oocytes.

    The optimum distance and duration of ultraviolet (UV) irradiation for the complete inactivation of African catfish Clarias gariepinus egg nucleus was investigated in this study. The UV light was suspended above the unfertilized eggs at four distances (5, 10, 20 and 30 cm) and for five durations (1, 2, 3, 4 and 5 min). Then, the irradiated eggs were activated with sperm from diploid C. gariepinus and cold shocked at 5°C for 5 min just moments before cell cleavage. Ploidy analysis was performed using karyotype chromosome counting. The results obtained suggested that the further the distance, the better the hatchability rate, however prolonged duration seemed to significantly reduced hatchability. All treatments with surviving progenies at the end of the study showed evidence of successfully diploid gynogen (2n = 56) induction at different percentages. However, the optimal protocol that gave a moderately high hatchability/survival rate and completely induced gynogens was exposure of the eggs to UV irradiation at 20 cm for 1 min. It was concluded that the distance and duration of UV irradiation affects gynogenetic induction in African catfish C. gariepinus.

    BACKGROUND: Bladder cancer ranked ninth of principal male cancer in Malaysia. This study aimed to evaluate the clinical characteristics and survival of bladder cancer patients in Malaysia.

    METHODS: A retrospective cohort study was conducted by obtaining records in the Malaysian National Cancer Registry. Patients aged 15 years old and above with diagnosis date between 2007 and 2011 were included. Death was updated until 31 December 2016. Five-year observed survival and median survival time were determined by the life table method and Kaplan-Meier estimate method.

    RESULTS: Among 1828 cases, the mean (SD) age of diagnosis was 64.9 (12.5) years. The patients were predominantly men (78.7%), Malay ethnicity (49.4%) and transitional cell carcinoma (78.2%). Only 14.8% of patients were at stage I. The overall five-year observed survival and median survival time was 36.9% (95% CI: 34.6, 39.1) and 27.3 months (95% CI: 23.6, 31.0). The highest five-year observed survival recorded at stage I (67.6%, 95% CI: 62.0, 73.3) and markedly worsen at stage II (34.3%, 95% CI: 27.9, 40.8), III (25.7%, 95% CI: 18.7, 32.6) and IV (12.2%, 95% CI: 8.1, 16.3).

    CONCLUSIONS: Survival of bladder cancer patients in Malaysia was lower with advancing stage. The cancer control programme should be enhanced to improve survival.

    As women with breast cancer are living longer, issues beyond survivorship like the much neglected sexual functioning and issue of quality of life have become increasingly important. Experiences of significant alterations in sexual functioning need to be addressed. However, these sexual issues are often not acknowledged in our traditional medical model of health care delivery. This paper briefly reviews the changes in sexual functioning after a diagnosis of breast cancer, with implication for clinical practice and medical curicula.

    Oral cancer is the sixth most common malignancy in the world. Despite recent advances in cancer diagnoses and therapies, the five-year survival rate of oral cancer patients has remained at a dismal 50% in the last few decades. Oral cancer is of major concern in Southeast Asia primarily because of the prevalent oral habits namely betel quid chewing, smoking and alcohol consumption. This paper provides a brief overview on the various aetiological agents and risk factors implicated in the development of oral cancer.

    This article presents a brief overview on the importance of adopting healthy behavior during and after the completion of primary cancer treatment. Increasing evidences are advocating physical activity engagement in cancer survivors due to its convincing beneficial outcomes. Today, outcomes from numerous trials confirmed the need to examine beyond physical activity engagement, into physical inactivity as an independent factor for cancer recurrences. Reducing cancer-risk related behaviors via increase physical activity and reduce inactivity is now receiving much attention in the field of cancer survivorship. Both realms of activity and inactivity are now acknowledged as influential independent factors contributing to better care in the field of cancer survivorship.

    Ki-67 expression is strongly correlated with tumour cell proliferation and growth. It is widely used as a proliferation marker in the routine pathological investigation. The nuclear protein Ki- 67 (pKi67) is recognised prognostic and predictive indicator for the biopsies assessment for cancer patients. Clinically, pKi67 has been revealed to associate with metastasis and the clinical stage of tumours. Furthermore, it has been presented that the expression of Ki-67 is significantly higher in malignant tissues with poorly differentiated tumour cells, as compared with normal tissue. The Ki-67 labelling index plays a vital role as an independent prognostic factor for survival rate, which includes all stages and grade categories. There is an association between the ratios of Ki-67 positive malignant cells and patient survival. This review provides an overview of recent advances in detecting Ki-67 in ovarian carcinoma.
