PMID: 15929636

Nonsteroidal anti-inflammatory drugs and their adverse effects on the gastric mucosa are yet another set of unresolved medical problems. This study examined the effects of various antioxidants on several gastric parameters after a single exposure to indomethacin. Forty-eight male rats of the Sprague-Dawley (200-250 g) strain were randomly divided to receive a single antioxidant (tocopherol, tocotrienol, or ubiquinone) or a combination of two (tocopherol-tocotrienol, tocopherol-ubiquinone or tocotrienol-ubiquinone) for 28 days. The rats were then challenged with a single dose of indomethacin and killed six hours later. Findings showed that the severity of gastric lesions was comparable in all groups. Only groups that received a combination of antioxidants exhibited reduced lipid peroxidation compared with all other groups (p < 0.05). The combination groups had a higher level of gastric prostaglandin E2 (PGE2) content compared with all other groups (p < 0.05). There was no significant difference among the groups in the gastric acid concentration and the glutathione/oxidized glutathione (GSH/GSSG) ratio. We conclude that although supplementation of these antioxidants in combination had desirable effects on lipid peroxidation and gastric PGE2 level, they did not reduce the lesions produced by indomethacin.

Hypertension is one of the commonest health problems in Malaysia and its cases are on a rise. In conjunction with the above statement, it is predictable that the cost of healthcare services will further increase in the future. Therefore, cost study is necessary to estimate the health related economic burden of hypertension in Malaysia. A cross sectional study was carried out to quantify the direct treatment cost of hypertension. Three hundred and ninety one hypertensive patients’ data from Bandar Tasik Selatan Primary Medical Centre in year 2010 were collected and analysed. The direct treatment costs were calculated. The result showed that out of 391 hypertensive patients, 12.5% was diagnosed hypertensive without any co-morbidity, 25.3% with 1 co-morbidity dyslipidemia only; 4.3% with diabetes mellitus type 2 only; 0.5% with chronic kidney disease only and none with ischaemic heart disease. Patients with 2 co-morbidities (dyslipidemia and diabetes mellitus type 2) were 42.2%; with 3 co-morbidities (diabetes mellitus type 2, dyslipidemia and chronic kidney disease) was 4.3%. The mean cost of direct treatment of hypertension per visit/ year was RM289.42 ±196.71 with the breakdown costs for each component were medicines 72.2%, salary 14.6%, laboratory tests 5.0%, administration 4.4% and radiology tests 3.8%. Dyslipidemia is by far the commonest co-morbidity among hypertensive patients. Direct costs of treating hypertension are mostly dependent on present of co-morbidity and numbers of drugs used. Thus, the annual budget could be calculated precisely in the future especially for drugs.

We evaluate the efficacy of recombinant DNA vaccine ABA392 against haemorrhagic septicaemia infection through intranasal administration route by targeting the mucosal immunity. The DNA vaccine was constructed and subjected to animal study using the Sprague Dawley (SD) rat. The study was divided into two major parts: (i) active and (ii) passive immunization studies, involving 30 animals for each part. Each group was then divided into five test groups: two test samples G1 and G2 with 50 and 100 µg ml-1 purified DNA vaccine; one positive control G5 with 106 CFU per ml formalin-killed PMB2; and two negative controls, G3 and G4 with normal saline and pVAX1 vector. Both studies were conducted for the determination of immunogenicity by total white blood cell count (TWBC), indirect ELISA and histopathological changes for the presence of the bronchus-associated lymphoid tissue (BALT). Our findings demonstrate that TWBC, IgA and IgG increased after each of the three vaccination regimes: groups G1, G2 and G5. Test samples G1 and G2 showed significant differences (P
The influence of narrative pedagogy on academic achievement and humanistic care ability of Chinese nursing students: A systematic review and meta-analysis

AIM: This study aims to compare the effects of narrative pedagogy with traditional teaching methods on nursing education outcomes.
BACKGROUND: Narrative pedagogy has been developed for over a decade, and while studies confirm that it can stimulate student interest, foster empathy, and enhance the integration of theoretical knowledge with practical skills in nursing care, there is still insufficient evidence to recommend its widespread adoption.
METHODS: In November 2024, a comprehensive search was conducted across databases including PubMed, Embase, The Cochrane Library, Web of Science, OVID, Scopus, PsychInfo, CNKI, Wanfang Data, Chinese Science and Technology Periodical Database (VIP) and China Biology Medicine disc (CBM) to identify studies that met the inclusion and exclusion criteria. Relevant data were extracted, and the quality of studies was assessed prior to conducting a meta-analysis. The review protocol was prospectively registered with the International Prospective Register of Systematic Reviews (PROSPERO)(CRD42024606820).
RESULTS: Out of an initial pool of 11748 articles, 41 studies were selected for meta-analysis after a rigorous screening process. The results indicate that narrative pedagogy significantly improves nursing students' final examination scores, practical skills, empathy, and professional identity compared with traditional teaching methods.
CONCLUSION: Narrative pedagogy effectively enhances nursing students' final examination performance, practical skills, empathy, and professional identity. However, given the limited number and quality of the included studies, these findings should be confirmed by further high-quality research.
TWEETABLE ABSTRACT: Narrative education has been used in nursing teaching for more than 15 years, but there is no evidence to show the effectiveness of narrative education in nursing students. Therefore, this study aims to conduct the first systematic review and meta-analysis of the learning effects of narrative education on nursing students. From the establishment of the database until November 2024, a systematic evaluation search was conducted on 11 databases. After careful screening process, 41 studies on narrative education of urination nursing students in China were selected for meta-analysis. The results show that narrative education is significantly better than traditional teaching methods in improving final exam scores, practical skills, humanistic care ability, empathy and professional identity. Given the limited number and quality of included studies, these findings should be confirmed by further high-quality studies.

Haemorrhagic septicaemia (HS) is a major disease in cattle and buffaloes, caused by certain serotypes of Pasteurella multocida, mainly B and E serotypes. Frequent HS outbreak has a major impact in many Asian countries, including Malaysia, where farmers encounter economic loss due to low milk production as well as death of their livestock. There are four types of vaccines available; broth bacterins, alum precipitated vaccine, aluminium hydroxide gel vaccine and oil adjuvant vaccine (OAV), but these vaccines can only provide short term immunity and therefore need to be administered annually. Hence, the development of a protein vaccine using recombinant antigen can be a potential candidate for the production of HS vaccine that would give longer immunity. We have successfully cloned the ABA392 gene fragment into a protein expression vector, pET-30a. The protein was expressed from our ABA392/pET30a clone and the immunogenicity of the protein has been tested on rats. This vaccine was able to trigger an immune response and therefore has the potential to be tested as suitable vaccine candidate in future studies. It is envisaged that this subunit vaccine will make a significant contribution in the management of HS among livestock in future.

The prevalence of tick-borne pathogens (TBP), Orientia tsutsugamushi, Rickettsia and Borrelia spp. in wild small animals, namely wild rodents, is now widely investigated. This study is to present the prevalence and distribution of O. tsutsugamushi, Rickettsia and Borrelia spp. in wild small animals and ticks collected from Gyeonggi and Gangwon provinces, Republic of Korea (ROK) in 2014. A total of 131 wild small animals, rodents and shrews, and 2,954 ticks were collected from Gyeonggi and Gangwon provinces from May to November 2014. The wild small animals (KR1-9) and ticks (K1-17) were grouped in accordance with capture dates and locations. Among the wild small animals, a total of 393 tissues and blood samples were extracted from six selected small animal series (KR1-3, KR6-8). Also, each date and location-grouped ticks were identified for its species and pooled according to the stage of development. Molecular identification for Rickettsia, Orientia, and Borrelia species was performed using polymerase chain reaction (PCR). To detect TBPs among wild small animals and ticks, primer sets targeting the 56 kDa protein encoding gene of Orientia spp., outer membrane protein B gene (OmpB) of Rickettsia spp., and 5S-23S intergenic spacer region (IGS) gene of Borrelia spp. were used. Of the 393 wild small animals' blood and tissue samples, 199 (50.6%) were positive for Orientia spp., 158 (40.2%) were positive for Borrelia spp., and 55 (14.0%) were positive for Rickettsia spp. Moreover, a total of 14 tick pools (n = 377) was positive for Rickettsia spp. (n=128, 34.0%) and Borrelia spp. (n=33, 8.8%). High prevalence of Orientia spp. and Rickettsia spp. in rodents and shrews were observed. This study presents significant insights by presenting data collected in 2014 that the prevalence of TBP was already high in mid 2010s. This study highlights the sustainable routine surveillance model for TBP.
