Aims The aim of this study was to compare the achievement of clinical targets for patients with type 2 diabetes mellitus (T2DM) in general medical clinics (GMCs) and specialist diabetes clinics (SDCs) for different hospital types (regional, provincial and community) in Thailand. Methods We used the medical records of patients ( n = 26,860) with T2DM from 595 hospitals (26 regional, 70 provincial and 499 community) across all 77 provinces in Thailand. Generalized linear mixed models were used to conduct multi-level modeling to evaluate the achievement of individual outcomes (A – glycated hemoglobin (HbA1c) <7.0% (53 mmol/mol), B – Blood Pressure (BP) <140/80 mmHg and C – LDL-Cholesterol <100 mg/dL) and aggregated outcomes ( AllABC – achieved all three of the targets, AnyABC – achieved at least one target, ABCcount – the number of targets achieved: 0, 1, 2 or 3). Results Neither clinic types (SDCs or GMCs) were consistency superior across all hospital types. For regional hospitals, SDCs were associated with higher odds of achieving BP, AnyABC , and ABCcount (OR = 1.55, 95%CI: 1.25–1.92, p < 0.001; OR = 1.35, 95%CI: 1.02–1.79; p = 0.04; RR = 1.10, 95%CI: 1.01–1.20, p = 0.03, respectively). For provincial hospitals, SDCs exhibited higher achievement of BP and LDL-C (OR = 1.52, 95%CI: 1.23–1.87, p < 0.001; OR = 1.28, 95%CI: 1.04–1.58, p = 0.02, respectively). For community hospitals, however GMCs demonstrated higher achievement of BP and AnyABC (OR = 0.81, 95%CI: 0.67–0.98, p = 0.03; OR = 0.74, 95%CI: 0.56–0.97, p = 0.03, respectively). Conclusions In larger (regional and provincial) hospitals, SDCs outperform GMCs in several (but not all) clinical targets. In contrast, in community hospital, where most patients with T2DM are serviced, GMCs were shown to have superior performance. [ABSTRACT FROM AUTHOR]

Background: Screening for opisthorchiasis, a parasitic worm infection affecting many millions of people in Southeast Asia, has traditionally relied on faecal egg examination such as the formalin-ethyl acetate concentration technique (FECT) and Kato-Katz method. Although the urinary enzyme-linked immunosorbent assay (ELISA) has been used more recently, we developed a urinary antigen-based rapid diagnostic test (RDT) to simplify diagnosis and as a point-of-care testing (POCT) and field applications for surveillance and control of opisthorchiasis. Methods: A urinary Opisthorchis viverrini (OV)-RDT was developed using immunochromatographic methodology with a specific monoclonal antibody against OV. The diagnostic performance of the urinary OV-RDT was compared to that of quantitative faecal FECT and urinary antigen ELISA (n = 493). Cross-reactivities of urinary OV-RDT with other helminthiases coexisted with O. viverrini were determined (n = 96). A field trial in the application of urinary OV-RDT was compared with urinary antigen ELISA at baseline screening and assessment of drug treatment outcomes in opisthorchiasis (n = 1629). The McNemar chi-square, Kruskal–Wallis and Cohen's kappa coefficient (κ-value) tests were used for statistical analyses. Results: Urinary OV-RDT had sensitivity of 94.2% and specificity of 93.2%, compared to faecal FECT. Urinary OV-RDT had high diagnostic agreement (Kappa = 0.842–0.874, P < 0.001) and quantitative correlation with urinary antigen ELISA (Kruskal–Wallis tests = 316.2, P < 0.0001) and faecal FECT (Kruskal–Wallis tests = 362.3, P < 0.0001). The positive rates by OV-RDT, ELISA and FECT were 48.9%, 52.5% and 49.3%, respectively. Cross-reactions of urinary OV-RDT with other helminthiases were few (2%). Field trials of urinary OV-RDT yielded comparable prevalence of O. viverrini between urinary OV-RDT (53.2%) and urinary antigen ELISA (54.0%). OV screening showed high diagnostic agreement (kappa > 0.8, P < 0.0001) between urinary OV-RDT and urinary antigen ELISA. The cure rates of opisthorchiasis at 1 month post-praziquantel treatment determined by urinary OV-RDT (86.6%) and urinary antigen ELISA (80.5%) were similar (P > 0.05). Conclusions: The urinary OV-RDT test has high potential as a new tool for screening and evaluating treatment outcomes in opisthorchiasis. The ease of sample collection and simplicity of urinary OV-RDT may facilitate mass screening, control and elimination of opisthorchiasis, thereby contributing to a reduction in the disease burden in Southeast Asia.

Focuses on a study which determined the prognostic factors of death in leptospirosis. Information on leptospirosis; Materials and methods; Results; Discussion.

Background Traumatic brain injury (TBI) is commonly accompanied by intracranial bleeding which can worsen after hospital admission. Tranexamic acid (TXA) has been shown to reduce bleeding in elective surgery and there is evidence that short courses of TXA can reduce rebleeding in spontaneous intracranial haemorrhage. We aimed to determine the effectiveness and safety of TXA in preventing progressive intracranial haemorrhage in TBI. Methods This is a double blinded, placebo controlled randomized trial. We enrolled 238 patients older than 16 years with moderate to severe TBI (post-resuscitation Glasgow Coma Scale (GCS) 4 to 12) who had a computerized tomography (CT) brain scan within eight hours of injury and in whom there was no immediate indication for surgery. We excluded patients if they had a coagulopathy or a serum creatinine over than 2.0 milligrams%. The treatment was a single dose of 2 grams of TXA in addition to other standard treatments. The primary outcome was progressive intracranial haemorrhage (PIH) which was defined as an intracranial haemorrhage seen on the second CT scan that was not seen on the first CT scan, or an intracranial haemorrhage seen on the first scan that had expanded by 25% or more on any dimension (height, length, or width) on the second scan. Results Progressive intracranial haemorrhage was present in 21 (18%) of 120 patients allocated to TXA and in 32 (27%) of 118 patients allocated to placebo. The difference was not statistically significant [RR = 0.65 (95% CI 0.40 to 1.05)]. There were no significant difference in the risk of death from all causes in patients allocated to TXA compared with placebo [RR = 0.69 (95% CI 0.35 to 1.39)] and the risk of unfavourable outcome on the Glasgow Outcome Scale [RR = 0.76 (95% CI 0.46 to 1.27)]. There was no evidence of increased risk of thromboembolic events in those patients allocated to TXA. Conclusions TXA may reduce PIH in patients with TBI; however, the difference was not statistically significant in this trial. Large clinical trials are needed to confirm and to assess the effect of TXA on death or disability after TBI. [ABSTRACT FROM AUTHOR]

A prospective, open-label, randomized trial at Khon Kaen Hospital (Thailand) was conducted from July 2000 through December 2001 to compare the clinical efficacies of ceftriaxone and sodium penicillin G for the treatment of severe leptospirosis. A total of 173 patients with severe leptospirosis were randomly assigned to be treated with either intravenous ceftriaxone (1 g daily for 7 days; n = 87) or intravenous sodium penicillin G (1.5 million U every 6 h for 7 days; n = 86). The primary outcome was time to fever resolution. Survival analysis demonstrated that the median duration of fever was 3 days for both groups. Ten patients (5 in each group) died of leptospirosis infection. There were no statistically significant differences in the duration of organ dysfunction. Ceftriaxone and sodium penicillin G were equally effective for the treatment of severe leptospirosis. Once-daily administration and the extended spectrum of ceftriaxone against bacteria provide additional benefits over intravenous penicillin. [ABSTRACT FROM AUTHOR]
