Left atrial volume index (LAVI) is well proven to be a reliable method of determining left atrial size, which has prognostic implications in cardiovascular diseases. Studies demonstrate that increased LAVI is a predictor of mortality in myocardial infarction, but its association with other major adverse cardiovascular events (MACEs) among patients post acute coronary syndrome (ACS) has not been adequately evaluated.
Penyakit lemah jantung merupakan antara lima punca utama kematian penyakit kronik tidak berjangkit berdasarkan rujukan World Health Organization. Sekitar 20% pesakit kegagalan jantung di seluruh dunia memasuki wad semula dalam jangka masa 30 hari selepas discaj. Hal ini demikian biasanya akibat daripada tidak mematuhi penyekatan sukatan air diminum atau pun perkembangan penyakit. Kajian ini bertujuan untuk mengenalpasti kadar masuk wad dalam 30 hari selepas discaj daripada kegagalan jantung dan faktor berkaitan di Pusat Perubatan Universiti Kebangsaan Malaysia (PPUKM) pada tahun 2016-2017 dengan menggunakan data casemix. Berdasarkan data kod, perbelanjaan digunakan untuk masuk wad semula dalam 30 hari diambilkira. Kadar masuk wad untuk kegagalan jantung dalam 30 hari selepas discaj bagi punca yang sama adalah 53.5% dan 43.5% bagi tahun 2016 dan 2017, sama kadar dengan hospital mengajar yang lain tetapi lebih tinggi daripada kadar di negara maju. Selepas diselaraskan, hanya faktor umur pesakit dan tahap keterukan penyakit menunjukkan kaitan yang bermakna dengan kemasukan wad dalam 30 hari selepas discaj bagi kegagalan jantung. Jangka masa berada dalam wad dan perbelanjaan untuk kemasukkan wad adalah lebih rendah daripada yang sepatutnya dicapai. Sebanyak RM80,329.73 telah dijimatkan pada tahun 2017 atas rawatan yang pantas dan rancangan penjagaan yang komprehensif diberi kepada 19.3% pesakit gagal jantung tahap keterukan tiga. Penurunan kadar kemasukan wad semula dalam 30 hari selepas discaj juga menjimatkan kos pesakit dan menunjukkan penjagaan klinikal yang mantap dan strategi rawatan yang rapi. Kajian casemix ini boleh digunakan sebagai rujukan untuk penentuan bajet bagi unit kardiologi di PPUKM.
The microbiological quality of thirty ready-to-eat (RTE) keropok lekor (a sausage shape Malaysian fish product) was evaluated in comparison to microbiological guidelines for ready to eat foods. The two E. coli isolates were subjected to DNA sequencing, identified and tested for their resistance towards fifteen different antibiotics. The survival and growth of the isolated E. coli strains inoculated in keropok lekor at atmospheric air and vacuum packaging were also evaluated. Results revealed that four samples (13.33%) contained Enterobacteriaceae counts that exceeded the recommended allowable counts of 4.0 log10 CFU/g. Unsatisfactory level of coliforms (< 1.7 log10 CFU/g) was also observed in ten of the samples; two of which contained E. coli (2.1 ± 0.17 and 3.7 ± 0.02 log10 CFU/g), suggesting of poor hygiene and sanitation practices. While the 'Possible E10' E. coli strain was observably resistant towards Nalidixic acid (30µg) alone, B10 E. coli isolate was worryingly resistant towards Ampicillin (10µg), Ceftazidime (30µg), Ciprofloxacin (5µg), Ceftriaxone (30µg), Nalidixic acid (30µg) and Tetracycline (30µg). This study also revealed that the growth and survival of the 'Possible E10' and B10 E. coli strains were not significantly affected by vacuum packaging when stored at both 4°C and 28°C. Therefore, intervention programmes to alert and educate smallmedium enterprisers (SMEs) of keropok lekor producers on food safety as well as potential health risks that can be associated due to inappropriate handling procedures of such product, merits consideration.
This study explores the opinions of Malaysian clinical specialists on the antibiotic prophylaxis against infective endocarditis (IE) as described in the 2008 National Institute for Health and Care Excellence (NICE) guideline. This cross-sectional study was performed from September 2017 to March 2019. The self-administered questionnaire comprised two sections: background information of the specialists and their opinions on the NICE guideline. The questionnaire was distributed to 794 potential participants, and 277 responded (response rate of 34.9%). In general, 49.8% of the respondents believed that clinicians should adhere to the guideline, although the majority of oral and maxillofacial surgeons (54.5%) actually disagreed with this view. The dental procedures that were perceived as presented moderate-to-high risk for IE were minor surgery for an impacted tooth with a recent episode of infection, dental implant surgery, periodontal surgery and dental extraction in patients with poor oral hygiene. The cardiac conditions that were strongly recommended for antibiotic prophylaxis were severe mitral valve stenosis or regurgitation and previous IE. Less than half of Malaysian clinical specialists agreed with the changes in the 2008 NICE guideline, contributing to their insistence that antibiotic prophylaxis is still needed for high-risk cardiac conditions and selected invasive dental procedures.
