RESUMO

We have previously isolated a novel avian Orthobunyavirus, Kedah Fatal Kidney Syndrome (KFKS) virus from a broiler farm in Kedah, Malaysia in 2020 with a severe kidney lesion in chickens. The virus was designated as KFKS2_CS virus. Sequence analysis of partial nucleocapsid (N) and nonstructural (NSs) sequence of this virus showed the highest sequence identity with previous KFKS1 from Malaysia (100%) and 97% with a zoonotic Umbre (UMB) virus, which was reported to cause encephalitis in immunocompromised humans in India. Phylogenetic analysis revealed that this virus was clustered together with previous KFKS1 virus from Malaysia, UMB and Cristoli viruses. This study aimed to assess the zoonotic potential of this KFKS2_CS virus in vitro by determining its ability to inhibit the production of interferon (IFN) in human glioblastoma multiforme (GBM) brain cells using reverse-transcriptase polymerase reaction (RT-PCR). This virus blocked the production of interferon-a in this human brain cells. In conclusion, this KFKS2_CS virus may have a zoonotic potential and become a public health concern in the future.

RESUMO

This is the first reported case of a mesenteric lymphatic malformation in a toddler in Malaysia. It is a rare benign condition with incidence of 1 in 250,000 populations. Our patient presented to us at 2 years 11months old complaining of abdominal distension for 6 months without obstructive symptoms. Clinically there was a vague soft central abdominal mass. CT abdomen done revealed a large multiloculated intraperitoneal mesentery cystic mass within the central abdomen extending to pelvis. A semi-emergency laparotomy was performed. Intra-operatively the multiloculated mesenteric cyst measured 20cm x 30cm, adherent to the small bowel beginning at 12cm from duodeno-jejunal junction. Resection of the mesenteric cyst with adherent small bowel and primary anastomosis was done. Histopathological examination revealed multiple large lymphatic channels of various sizes in the mucosa and submucosa. Our patient has no signs of recurrence and remains symptom-free after 1 year since his surgery. Surgery with clear margins of resection is the recommended gold standard based on available literature. Type of surgical resection required will depend on the type of mesenteric lymphatic malformation. An awareness of this rare pathology is required to ensure proper management is given to these patients.

RESUMO

Toxoplasma gondii is a protozoan parasite that is capable of causing a zoonotic disease, known as toxoplasmosis. Vertical transmission of T. gondii from the mother to the fetus, during pregnancy may cause severe complications to the developing fetus. This current study aimed to determine the seroprevalence and investigate the associated risk factors of Toxoplasma infection in pregnant women (n=219) visiting the antenatal clinic at UMMC. While the elevated level of anti-Toxoplasma IgG and IgM antibodies indicates the presence of infection, it fails to differentiate between a past and a recent infection. Thus, the study also demonstrates the usefulness of IgG avidity in validating the timing of infection. The serum samples were tested for the presence of anti-Toxoplasma IgG and IgM antibodies by ELISA test, and the seropositive samples for both anti-Toxoplasma IgG and IgM antibodies were further evaluated by IgG avidity. The results showed that the overall prevalence of T. gondii seropositivity was 34.7%. Of these, 30.6% (67/219) were positive for anti-Toxoplasma IgG antibody only, 2.3% (5/219) were positive for anti-Toxoplasma IgM only, and the remaining 1.8% (4/219) was positive for both anti-Toxoplasma IgG and IgM antibodies. All of the pregnant women who were positive for both anti-Toxoplasma IgG and IgM antibody were found to have past infection when evaluated by IgG avidity. In this study, Malay ethnicity and the number of existing previous children were significantly associated with T. gondii seropositivity (p<0.05). Based on these findings, information and education on the transmission and prevention of congenital toxoplasmosis are very crucial as a public health effort towards a healthier society.

RESUMO

OBJECTIVE: To evaluate immediate compared with on-demand full maternal oral feeding after caesarean delivery STUDY DESIGN: A randomised trial. SETTING: Obstetric unit of a university hospital in Kuala Lumpur, Malaysia. POPULATION: Women admitted for a planned caesarean under spinal anaesthesia. METHODS: Participants were randomised to a sandwich meal served immediately on return to the ward or on-demand. MAIN OUTCOME MEASURES: Primary outcomes were patient satisfaction VAS (visual analog scale of 100 mm) on the feeding regimen and vomiting at 24 hours. RESULTS: 453 women were initially enrolled, 395 were randomised and available for analysis. Median (full range) patient satisfaction VAS scores were 82 (15-100) versus 84 (0-100) mm, P = 0.88 and vomiting rates were 1/197 (0.5%) versus 2/198 (1.0%), P > 0.99 for immediate compared with on-demand feeding, respectively. The immediate versus on-demand arms first ate at a median of 105 (35-210) versus 165 (45-385) minutes, P < 0.001, had second meal at 5.3 (1.2-15.5) versus 5.8 (2.2-29.7), P < 0.001, flatus passage at 9.5 (3.1-29.0) versus 10.3 (2.8-24.6), P = 0.023 hours post-caesarean and opiate analgesia use was 10/197 (5.1%) versus 23/198 (11.6%), P = 0.028, RR 0.4 (95% CI 0.2-0.9), NNTb 16 (95% CI 8-89). The median visual numerical rating scale (0-10 scale) for nausea and bloating at 8, 16 and 24 hours was similarly scored at zero in both arms. Other outcomes were similar. CONCLUSION: Immediate full feeding has some advantage over on-demand feeding. Both regimens are tolerated well. Patients probably should be fed as soon as practicable after a caesarean. TWEETABLE ABSTRACT: Full maternal oral feeding should commence as soon as practicable after an uncomplicated caesarean section.

RESUMO

A peripheral intravenous catheter is often inserted as part of care during labour. The catheter is inserted into the back of the hand or lower forearm vein in usual practice. There is no trial data to guide the care provider on which is the better insertion site in any clinical setting. 307 women admitted to the labour ward who required insertion of intravenous catheter were randomised to back of hand or lower forearm vein catheter insertion. Catheter insertion is by junior to mid-grade providers. We evaluated insertion success at the first attempt, pain during insertion and catheter replacement due to malfunction as main outcomes. After catheter removal, we recorded patient satisfaction with site, future site preference and insertion site swelling, bruising, tenderness, vein thrombosis and pain. Insertion of a catheter into back of hand vein is more likely to be successful at the first attempt. Insertion pain score, catheter replacement rate, patient satisfaction, patient fidelity to site in a future insertion and insertion site complications rate are not different between trial arms. In conclusion, both insertion sites are suitable; the back of the hand vein maybe easier to cannulate and seems to be preferred by our frontline providers.

RESUMO

In this article we present ultra-sensitive, silicon nanowire (SiNW)-based biosensor devices for the detection of disease biomarkers. An electrochemically induced functionalisation method has been employed to graft antibodies targeted against the prostate cancer risk biomarker 8-hydroxydeoxyguanosine (8-OHdG) to SiNW surfaces. The antibody-functionalised SiNW sensor has been used to detect binding of the 8-OHdG biomarker to the SiNW surface within seconds of exposure. Detection of 8-OHdG concentrations as low as 1 ng/ml (3.5 nM) has been demonstrated. The active device has been bonded to a disposable printed circuit which can be inserted into an electronic readout system as part of an integrated Point of Care (POC) diagnostic. The speed, sensitivity and ease of detection of biomarkers using SiNW sensors render them ideal for eventual POC diagnostics.

RESUMO

BACKGROUND: Mullerian adenosarcoma of the uterine cervix is a rare tumor seen in young women of reproductive age group. It presents as cervical polyps and is a low-grade malignancy with a tendency for local recurrence. Diagnosis can be difficult since it can easily be mistaken for benign polyps, both clinically and pathologically. CASE: We present three cases of adenosarcoma of the cervix presenting as cervical polyps and review the clinical and pathological features of these tumors. CONCLUSION: Adenosarcoma of the cervix should be ruled out especially in women presenting with recurrent cervical polyps. A careful histological examination is mandatory, important prognostic factors being myometrial invasion and sarcomatous overgrowth. Distant metastasis is very rare and therapy can be tailored to suit patient's needs but long term follow-up is essential.

RESUMO

The pesticide residues which were detected in fish tissues are DDT, DDE, aldrin, dieldrin and deltamethrin. In total 45 samples were taken out of which 18 were found positive. Out of 18 samples DDT was found in 10 samples in small quantities. DDE was found in 12 samples in higher quantities, aldrin was found in 10 samples and dieldrin was found in 2 samples in small quantities. Deltamethrin was found in 7 samples and malathion in none. Slightly more number of residues were found in Kalri lake samples. However, quantity of pesticides was higher in Haleji lake due to polluted nature of water while number of pesticides was more in Kalri lake water, possibly due to the surrounding adjacent agricultural farms. Higher level of GPT, GOT and ALP was found in samples with higher accumulation of pesticide residues. This possibly indicates a correlation between exposure of pesticide and increased level of the 3 enzymes.

RESUMO

A total of 200 pregnant women were recruited in this cross-sectional study. The overall seroprevalence of toxoplasmosis in pregnant women was found to be 49%, in which 39%, 4% and 6% for anti-Toxoplasma IgG, IgM and both anti-Toxoplasma IgG and IgM antibodies, respectively. We found the differences in Toxoplasma seroprevalence rates among the races were significant: the highest rate was in the Malays (55.7%), followed by the Indian (55.3%) and the Chinese (19.4%) (P<0.05) populations. An increase in Toxoplasma seroprevalence with increasing parity was detected (P<0.05). Women with no children had a prevalence of 39.7%, while women with one or more than two children had a prevalence of 44.2% and 62.9%, respectively. In this study, there was no significant association between Toxoplasma seroprevalence and various possible risk factors in pregnant women (P>0.05). When multivariate analysis was performed, no significant association between Toxoplasma seroprevalence and history of contact with cats, consumption of undercooked meat and blood transfusion was found (P>0.05). We did not find any newly diagnosed cases of acute acquired toxoplasmosis in pregnancy during the study period.

RESUMO

Toxicity of a synthetic pyrethroid (Danitol 10 E.C.), methoprene (J.H.A.) and crude neem extract formulation (RB-b +PBO +Tx) in synergestic form was determined in laboratory by contact method against adults of Sitophilus oryzae. Observations after 24 hours of treatment showed that 50% of the adults died at 0.39 mu/cm(2) of Danitol, 6.28 mug/cm(2) of neem formulation and 18.85 mug/cm(2) of methoprene, the three products used in this experiment. Danitol was found more effective as compared to neem formulation and methoprene. It was found that the plant product formulation and a synthetic product are more effective than methoprene.
