OBJECTIVES: To describe the effects of electrical stimulation (ES) therapy in the 4-week management of two sub-acute spinal cord-injured (SCI) individuals (C7 American Spinal Injury Association Impairment Scale (AIS) B and T9 AIS (B)).
SETTING: University Malaya Medical Centre, Kuala Lumpur, Malaysia.
METHODS: A diagnostic tilt-table test was conducted to confirm the presence of orthostatic hypotension (OH) based on the current clinical definitions. Following initial assessment, subjects underwent 4 weeks of ES therapy 4 times weekly for 1 h per day. Post-tests tilt table challenge, both with and without ES on their rectus abdominis, quadriceps, hamstrings and gastrocnemius muscles, was conducted at the end of the study (week 5). Subjects' blood pressures (BP) and heart rates (HR) were recorded every minute during pre-test and post-tests. Orthostatic symptoms, as well as the maximum tolerance time that the subjects could withstand head up tilt at 60°, were recorded.
RESULTS: Subject A improved his orthostatic symptoms, but did not recover from clinically defined OH based on the 20-min duration requirement. With concurrent ES therapy, 60° head up tilt BP was 89/62 mm Hg compared with baseline BP of 115/71 mm Hg. Subject B fully recovered from OH demonstrated by BP of 105/71 mm Hg during the 60° head up tilt compared with baseline BP of 124/77 mm Hg. Both patients demonstrated longer tolerance time during head up tilt with concomitant ES (subject A: pre-test 4 min, post-test without ES 6 min, post-test with ES 12 min; subject B: pre-test 4 min, post-test without ES 28 min, post-test with ES 60 min).
CONCLUSIONS: Weekly ES therapy had positive effect on OH management in sub-acute SCI individuals.
METHODS: In order to evaluate the toxicity of Lantana camara, the acute toxicity of the methanolic extract on adult mice and cytotoxicity test on Vero cell line were investigated. A fixed large dose of 2 g/kg body weight of L. camara leaf extract was administrated by a single oral gavage according to the OECD procedure.
RESULTS: In 2 weeks, L. camara leaf extract showed no obvious acute toxicity. While female mice lost body weight after being treated with single dose of leaf extract in acute toxicity test, male ones lost organ mass, particularly for heart and kidney. The biochemical liver function tests showed significantly elevated TBIL and ALT in the L. camara leaf extract treated female mice group compared with the control group. Cytotoxicity effect of leaf extract of L. camara was estimated through a MTT assay. Cytotoxicity tests on Vero cell line disclosed that leaf extract at concentrations up to 500 µg/mL inhibited the growth of cells 2.5 times less than did Triton 100 × 1%. More interestingly, the cytotoxicity initiated to decline at elevated concentrations of this extract.
CONCLUSIONS: The results of both tests confirm that L. camara shows a pro toxic effect.
METHODS: This was an open-label, prospective, observational study involving 339 patients from Indonesia, Pakistan, Malaysia, Thailand, and Singapore. Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression Severity scale (CGI-S), and safety parameters were assessed.
RESULTS: 62% of patients responded to olanzapine treatment, defined a priori as a reduction in BPRS of > 40% from baseline. Following the 8-week treatment period, the BPRS total, BPRS positive, BPRS negative, and CGI-S scores decreased by 18.7 (95% CI: 17.4, 20.2), 6.1 (5.6, 6.6), 2.9 (2.6, 3.2), and 1.5 points (median 1.0), respectively (p < 0.0001). In total, 31 of the 339 patients (9.1%) failed to complete the study according to the study description. Loss to follow-up and personal conflict were the most common reasons for discontinuation. There were 30 treatment-emergent adverse events with six serious cases, assessed as unrelated to study drug, reported.
CONCLUSION: This study further demonstrates the effectiveness and safety of olanzapine in actual clinical practice settings, in reducing the severity of psychopathological symptoms in Asian patients with schizophrenia.
METHODS: Out of 105 patients with IHD, 76 completed self-administration of HeartQoL at the clinic followed by at home within a 2-week interval. In retest, patients responded using non-interview methods (phone messaging, email, fax, and post). Phone interviewing was reserved for non-respondents to reminder.
RESULTS: Reliability of HeartQoL was good (intraclass correlation coefficients = 0.78-0.82), was supported in the Bland-Altman plot, and was comparable to five studies on MacNew of similar retest interval (MacNew-English = 0.70-0.75; translated MacNew = 0.72-0.91). Applicability of its standard error of measurement (0.20-0.25) and smallest detectable change (0.55-0.70) will depend on availability of normative data in future.
CONCLUSION: The reliability of HeartQoL is comparable to its parent instrument, the MacNew. The HeartQoL is a potentially reliable core IHD-specific HRQoL instrument in measuring group change.
