The purpose of the current study was to isolate and identify subclinical mastitis causing bacteria from milk samples of dairy goats. The milk samples from individual dairy goats were collected from several dairy goat farms around Kota Bharu, Kelantan. Major bacterial isolates were Staphylococcus spp. (73.2%). Coagulase negative staphylococci encompassing 68.3% of the isolates, whereas 4.9% was coagulase positive staphylococci. Bacillus spp. constituted 12.2% out of the isolates. Listeria spp. and Neisseria spp. both were represented 7.3%. There is a need to discuss the potential hazards of these bacteria in affecting milk quality, health of goats and food safety to consumers. The findings also emphasize the need to study the exact species of bacteria isolated in order to plan for their prevention as well as to assist veterinarians in prescribing correct antibiotic therapy.
This report documents a case of 5-month old intact male German Shepherd dog diagnosed with pythiosis on its left forelimb. This is the first ever reported case of pythiosis presented at the University Veterinary Teaching Hospital (UVH), Universiti Putra Malaysia and may be the first ever reported incidence in Malaysia with a complaint of a chronic non-healing wound. The case became complicated as the dog was concurrently infected with a mixed bacterial infection and the identified bacteria were resistant towards a number of antibiotics tested. The antibiotic that was determined to be sensitive was only able to act on certain bacteria and not to the others. The journey of getting to the final diagnosis was almost impossible if we had not tried different media preparation: with and without Dermasel supplement; and through molecular approach using amplification at ITS region followed by DNA sequence analysis. The unwarranted lack during the diagnosis process of this incidence has made us more aware of the presence of Pythium insidiosum in Malaysia and plan for a more strategize ways of diagnosing the suspected fungus at laboratory setting in future. The objective of this paper is to share our experience and reflection on the diagnosis of the rare incidence of pythiosis present in Malaysia.
The study investigates the use of the various parameters of the semen analysis in predicting the fertility outcome in 82 infertile couples. The sperm density, % progressive motility, % normal morphology were divided into 'normal' and 'abnormal' based on the criteria proposed by WHO. The subsequent cumulative pregnancy rates were then calculated according to this criteria. A life-table method of analysis was used. All female related fertility factors were excluded. With the exception of a sperm density of less than 20 x 10(6) per ml the other parameters showed no significant correlation with the cumulative pregnancy rates at 12 months or 24 months respectively. We concluded that the semen analysis does not predict the probable outcome of the subsequent rates even when female fertility related factors were excluded apart from a sperm density less than 20 x 10(6) per ml.
Results of a biodiversity study of Antarctic microfungi from ornithogenic soils are presented in this paper. A wide range of soil habitats within and adjacent to active and abandoned penguin rookeries were sampled in order to examine relationships between environmental factors and the biodiversity of soil microfungi. Soil samples were collected from two contrasting Antarctic locations: (1) Beaufort Island (Ross Sea, Continental Antarctica), which is largely ice- and snow-covered, isolated, difficult to access and infrequently visited, and (2) Barrientos Island (maritime Antarctica) which is mostly ice-free during summer and is often visited by scientists and tourists. Soil sampling at Beaufort and Barrientos Islands was completed during the austral summer seasons of 2004/05 and 2006/07, respectively. Warcup’s soil method was used for fungi cultivation. A total of 27 fungal taxa were isolated from the two study sites, consisting of 11 ascomycetes, 13 hyphomycetes
and three yeasts. Only three taxa — Geomyces sp., a pink and a white yeast — occurred on both sites. The isolated fungi were classified according to their thermal characteristics in culture, with seven psychrophilic, 10 psychrotrophic and 10 mesophilic fungi being isolated. Thelebolus microspores, Thelebolus sp., Geomyces sp. and Antarctomyces sp., were the most frequently isolated fungi. A total of 10 taxa were isolated from the 20 soil samples from Beaufort Island, consisting of five psychrophilic, four psychrotrophic and one mesophilic fungi. Thelebolus microsporus, Thelebolus sp., Asco BI8 and Phoma sp. were the most frequently obtained fungi
(20%–27% of isolates). A total of 22 fungal taxa were isolated from 23 soil samples from Barrientos Island, consisting of four psychrophilic, six psychrotrophic and 12 mesophilic fungi. Geomyces sp. and Antarctomyces sp. were the most frequently isolated taxa. Thus, the fungal diversity of Beaufort Island was dominated by Ascomycetes while that of Barrientos Island was dominated by hyphomycetes.
There are relatively little data on bacteria with antimicrobial activities from Antarctic, especially from the South Shetland Islands when compared to the other parts of the world. Hence, this project was set to isolate and characterize bacteria that produce anti-microbial compounds from Greenwich Island (one of the South Shetland Islands), Antarctica. A total of 356 strains of bacteria were isolated from Greenwich Island. They were screened for antimicrobial activities against 13 Gram-negative and one Gram-positive indicator food-borne pathogens. Two out of the 356 Antarctic bacterial strains exhibited an antagonistic effect on the indicator strains, Escherichia coli, Salmonella spp., Klebsiella pneumoniae, Enterobacter cloacae, Vibrio parahaemolyticus and Bacillus cereus. The two Antarctic bacterial strains were designated as SS157 and SR13. Biochemical and 16S rDNA analysis indicated that the strain SS157 was closely related to Pseudomonas congelans while the strain SR13 was closely related to Pseudomonas tremae. The anti-microbial compounds produced by the two Antarctic bacteria were not sensitive to temperature and were not degraded by trypsin or pronase indicating that they were likely to be chemical compounds or antibiotics. Antimicrobial compounds from strains SS157 and SR13 were broad spectrum, and targeted both Gram-positive and negative pathogens.
We compared the analgesic profile between patient-controlled analgesia (PCA) using oxycodone and morphine in post total abdominal hysterectomy patients. Eighty-four ASA I or II patients, aged 18 to 65 years who underwent total abdominal hysterectomy were recruited into this prospective, double blind, randomised controlled study. They were randomised to receive either PCA oxycodone 0.7 mg per bolus or PCA morphine 1 mg per bolus for postoperative pain relief. At the end of surgery, all patients received IV morphine 0.1 mg/kg and skin incision was infiltrated with 20 mls of bupivacaine 0.25%. Post-operative pain scores, opioids consumptions, sedation scores and side effects were assessed upon arrival and at 30 minutes after arrival to recovery area, as well as at 6 hours and 24 hours after the operation in the ward. Patients’ overall satisfaction was also assessed 24 hours postoperatively.No significant differences were observed in terms of postoperative pain scores, opioids consumption, sedation scores, side effects as well as patient’s overall satisfaction between the PCA oxycodone and PCA morphine group. Oxycodone was comparable to morphine as PCA in terms of total opioid consumption, pain scores and satisfaction level for patients undergoing total abdominal hysterectomy and therefore may be an alternative to morphine in postoperative pain management as PCA.
To investigate the aetiology of rhinitis occurring in pregnancy, by (1) describing the relationship between pregnancy rhinitis and serum oestrogen, progesterone, placental growth hormone and insulin-like growth factor, and (2) assessing the prevalence of pregnancy rhinitis among Malaysian women.
Alphacypermethrin (Fendona) and lambda-cyhalothrin (Icon) were evaluated against sentinel bloodfed adults and 4th-instar larvae of Aedes aegypti in a housing estate in Malaysia. The impact of both pyrethroids on field populations of Ae. aegypti and Aedes albopictus were monitored weekly using oviposition trap samples. Both alphacypermethrin and lambda-cyhalothrin showed adulticidal and larvicidal effects.
Uterine leiomyoma is found in approximately 2% of pregnant women. One in ten women will have complications related to myoma in pregnancy. Myomectomy during pregnancy especially at Caesarean section is much discouraged in the literature. We present here 2 cases of large uterine myoma, situated in the anterior aspect of the lower segment, complicating pregnancy at term. Myomectomy in both instances allowed delivery of the fetus through the lower segment, making vaginal delivery in subsequent pregnancies possible.
The major limitation of direct application of tannery sludge compost in agriculture is the total heavy metal contents and their bioavailability to the soil-plant system. This study focused on the heavy metal characterization and the influence of changing the physicochemical properties of the medium throughout the composting on the concentrations, bioavailability or chemical forms of Cr, Cu, Zn, Pb and Cd in tannery sludge. The study shows that throughout the 60 days of composting, physicochemical analysis and Fourier-transformed infrared (FTIR) spectroscopic characterization show that all parameters elaborated and reached relatively stable levels reflecting the stability and maturity of the final product, and revealed the biodegradation of components that can be easily assimilated by microorganism. The C/N ratio reaches the optimal range of stable compost; inorganic nitrogen is transformed into stable organic forms. The total concentration of Cr, Zn, Cu, Pb and Cd is very low rendering final compost acceptable for agricultural use. The germination index for both Chinese cabbage and lettuce was 97% after 60 days of composting, showing that the final compost was not phytotoxic. Furthermore, in using a sequential extraction method in sludge compost at different phases of treatment, a less than 2% of metals bound to bioavailable fractions X-(KNO(3)+H(2)O). A large proportion of the heavy metals were associated to the residual fraction (75-85%) and more resistant fractions to extraction X-NaOH, X-EDTA, X-HNO(3) (15-25%). Mobile fractions of metals are poorly predictable from the total content. Bioavailability of all fractions of elements tends to decrease.
Tannery waste is categorized as toxic and hazardous in Malaysia due to its high content of Cr (in excess of 500 mg/kg) and other heavy metals. Heavy metals, when in high enough concentrations, have the potential to be both phytotoxic and zootoxic. Heavy metals are found as contaminants in tannery sludge. This investigation aimed to identify the fate of chromium, cadmium, copper, lead, and zinc concentrations in tannery sludge throughout a 50-day composting cycle. The results of this study showed a general increase in the removal of Cr, Cd, Pb, and to a much smaller extent Zn and Cu, manifested by a decrease in their overall concentrations within the solid fraction of the final product (the decreases were likely the result of leaching). Furthermore, in using a sequential extraction method for sludge composting at different phases of treatment, a large proportion of the heavy metals were found to be associated to the residual fraction (70-80%) and fractions more resistant to extraction, X-NaOH, X-EDTA, X-HNO3 (12-29%). Less than 2% of the metals were bound to bioavailable fractions X-(KNO3+H2O).
Nine species of parasitoids were found parasitizing the pupae of filth flies breeding in refuse dumps and poultry farms throughout peninsular Malaysia. Spalangia were most common, consisting of Spalangia endius Walker, S. cameroni Perkins, S. gemina Boucek, S. nigroaenea Curtis, and two undescribed species. Other parasitoids collected were Pachycrepoideus vindemmiae Rondani, Dirhinus himalayanus Westwood, and an unidentified Hymenoptera. The parasitized fly hosts included Musca domestica L., Chrysomya megacephala (F.), Fannia sp., and Ophyra sp. S. endius was the most common parasitoid attacking M. domestica and C. megacephala at refuse dumps and poultry farms D. himalayanus were found to parasitize only M. domestica pupae collected at poultry farms.
A study on population patterns of the parasitoid Spalangia endius Walker at a dumping ground near Kuala Lumpur city showed that the percentage of S. endius adult emergence varied seasonally. During the relatively heavy rainfall months of August and November 1988, and January, March, and April 1989, the population of S. endius adult emergence were low (0-14.2%) compared to the less rainy months of July, September, and December 1988, and May 1989 (29.3-39.6%). This information could be useful in formulating strategies to reduce house fly population at the refuse dumping ground through integrated pest management programs.
An Intrauterine contraceptive devices (IUCD) is commonly inserted by the primary health care physician. It can migrate into pelvic or abdominal organs. When a pregnancy occurs following an insertion of an IUCD, there should be a high suspicion of uterine perforation or possible migration. A radiograph can be done in the primary health care clinic to search for a missing IUCD. Early referral to the urology service is warranted when a patient presents with recurrent urinary tract infections. Removal of an intravesical IUCD can be managed with cystoscopy, laparoscopy or open surgery. Herein, we report a case of IUCD migration into the bladder. This case will highlight the importance of proper technique, careful insertion and the role of ultrasound.
The object of this study is to determine the status of an urban Malaysian woman in her menopause age group with reference to her menopausal symptoms, lipid profile, breast, pelvis and bone. One hundred and sixty four women attending the Menopause Clinic of University Hospital, Kuala Lumpur who had not previously been on hormone replacement therapy were studied. Forty nine women were perimenopausal, 74 women were in early menopause (within 5 years of menopause) and 41 women were in late menopause (after 5 years of menopause). The most common symptoms were hot flushes (56%) and generalised tiredness (49%). Eighty four percent (84%) of women had high cholesterol levels. Serum triglycerides were highest in the late menopause group. There were 2 cases of intraductal carcinoma diagnosed on routine mammography, with 8 cases of fibrocystic breast disease and 7 cases of suspicious breast lumps. Routine ultrasound (pelvic and abdominal) revealed two women with ovarian cysts, 6 women with an endometrial thickness of more than 5 mm and 8 women with uterine fibroids. Eighty five women (51.8%) had mild osteoporosis while four women had moderate osteoporosis on dual photon measurements for bone mineral density. Menopause clinics should aim at investigating a woman in her menopause as a whole. Vasomotor symptoms were common in the urban Malaysian menopausal woman. There was a high incidence of lipid abnormalities. Routine mammography, pelvic ultrasound examinations and bone mineral density tests detected significant pathology and abnormalities.

INTRODUCTION: Coitus and orgasm in late pregnancy are believed to facilitate the onset of labour. We aim to evaluate the relationship at term of reported coitus and orgasm with spontaneous labour.
METHODS: Women at term scheduled for non-urgent labour induction were asked to keep a coitus and orgasm diary. These women were recruited for a randomised trial on the effect of coitus to promote spontaneous labour. For this analysis, the women were categorised into coitally-active and abstinent groups according to their coital diary. Spontaneous labour prior to the date of scheduled labour induction was the primary outcome. Labour, delivery and neonatal outcome were also evaluated. Multivariable logistic regression analysis was used to control for significant variables.
RESULTS: On univariate analysis, the inverse association of coitus with spontaneous labour was borderline (odds ratio [OR] 0.6; 95 percent confidence interval [CI] 0.3-1.0; p-value is 0.052). Orgasm was not associated with spontaneous labour (p-value is 0.33). After adjustment, coitus (adjusted OR 0.4; 95 percent CI 0.2-0.8; p-value is 0.009) displayed a significant inverse association with spontaneous labour. Coitus and orgasm were not associated with any other adverse pregnancy outcome.
CONCLUSION: Women who reported coitus were less likely to go into spontaneous labour prior to their scheduled labour induction. Reported coitus and orgasm were not associated with adverse pregnancy outcome.
Caesarean delivery rates are still increasing, and reliable predictors of adverse outcomes at a subsequent trial of scar are important as they guide decision-making on the best mode of delivery. We aimed to evaluate whether there are any predictors for caesarean delivery and neonatal admission, following trial of labour after one lower transverse caesarean section.
Adaptive performance will increasingly be confronted with new insights as society today changes constantly. This raises questions as to what factors will impact employee's adaptive performance and what is their inner psychological mechanism. The terms of positive psychology and adaptive performance are important concepts in the domain of organizational behavior and human resource development areas. The literature, however, lacks a systematic review of it. Our research seeks to explore the inherence of employee adaptive performance via the prism of positive psychology, including Psychological Capital and PERMA (Positive Emotions, Engagement, Relationships, Meaning and Accomplishment). We selected 27 papers out of 382, which were generated from Web of Science and Scopus databases associated the keywords of the two concepts, and used the 2020 PRISMA flow program for the paper screening. By analyzing the underpin theories, the causation, and the measurement, we discovered that there is a complex and nuanced relationship between positive psychology and adaptive performance, and most of the research to date suggests that positive psychology components improve employee adaptive performance. This study maps the current knowledge at the nexus of positive psychology and adaptive performance to identify existing gaps and potential for further investigation.
