ABSTRACT

OBJECTIVE: The study aims to assess the seroprevalence of Toxocariasis and its associated risk factors among individuals attending the outpatient department at Tra Vinh University Hospital, Vietnam, in 2022. SUBJECTS AND METHODS: A cross-sectional survey was conducted among outpatients of Tra Vinh University Hospital. Toxocariasis diagnosis was based on the Enzyme-Linked Immunosorbent Assay (ELISA) performed at the hospital's laboratory department. We assessed the seroprevalence of Toxocariasis and evaluated associated risk factors, including demographics and certain behaviors. RESULTS: Of the 249 participants surveyed, 165 tested positive for Toxocariasis, yielding a seroprevalence of 66.3% (95% CI: 60.4-72.1). Multivariate analysis revealed that age groups up to 30 and 30-60 years had higher odds of Toxocariasis infection, with adjusted odds ratios (aOR) of 2.52 (95% CI: 1.04-6.11) and 3.21 (95% CI: 1.44-7.15) respectively. Additionally, individuals residing in rural areas and those in contact with dogs or cats had increased risks, with aORs of 2.21 (95% CI: 1.21-4.01) and 2.04 (95% CI: 1.10-3.79), respectively. Notably, hand washing before eating emerged as a protective factor against Toxocariasis, presenting an aOR of 0.38 (95% CI: 0.19-0.76). CONCLUSIONS: Our findings underscore a significant seroprevalence (66.3%) of Toxocara spp. among outpatients at Tra Vinh University Hospital. Proactive measures, including hand hygiene before meals and after pet interactions, are advocated. There is a pronounced need for community-level epidemiological surveillance for human Toxocariasis.

ABSTRACT

BACKGROUND AND PURPOSE: We present the early experience in thrombolysis in three major centers of Ho Chi Minh city, namely 115 People Hospital, Gia Dinh Hospital, and An Binh Hospital. METHODS: A prospective study of consecutive patients treated with intravenous tPA with a treatment protocol similar to that of the National Institute of Neurological Disorders and Stroke (NINDS) trial. National Institutes of Health Stroke Scale (NIHSS) scores on admission and Modified Rankin Scale (MRS) scores at 3 months were measured for all patients. Intracranial and systemic hemorrhagic complications were recorded. RESULT: A total of 121 of 6171 (2%) patients with acute IS received thrombolysis over 3 years. Mean age was 57 years (range 18-78) and initial median NIHSS score was 12 (range 5-23). The mean delay between symptom onset and treatment was 143 min (range 50-210). Seventy-three (60.3%) patients received the standard dose with the remaining 48 patients (36.9%) treated with a lower dose, a mean calculated dose of 0.62 mg/kg (range, 0.6-0.86 mg/kg). Over half (56.3%) of the patients receiving low dose achieved functional independence (mRS score 0-1) at 3 months compared with 34.2% in the standard-dose group (P = 0.01). The 3-month mortality rate was also higher in the standard-dose group (2.1% vs. 12.5% with standard-dose tPA; P = 0.04). Symptomatic intracranial hemorrhage was noted in four patients of standard-dose group and one patient of low-dose group (P = 0.36). CONCLUSION: Intravenous thrombolysis, particularly in a lower dose, is safe and feasible in the treatment of acute IS in our selected Vietnamese population.

ABSTRACT

Single crystals of the type-I clathrate Ba(8)Ni(3.5)Ge(42.1)square(0.4) (space group Pm3n, no. 223, a = 10.798(2) A, l = 30 mm, slashed circle = 8 mm) were grown from the melt using the Bridgman technique. Their composition, determined by microprobe analysis, reveals a distinctly lower Ni content than previously reported for the lower limit (x = 5.4) of the homogeneity range of the clathrate-I phase Ba(8)Ni(x)Ge(46-x). From single crystal X-ray diffraction data we introduce a crystal structure model that takes point defects (vacancies) square in the Ge network into account. It reveals that both Ni and square accumulate at a single site (6c) and that, as a consequence, the Ge network distorts considerably. Ba(8)Ni(3.5)Ge(42.1)square(0.4) shows metal-like behaviour (drho/dT > 0) albeit with high resistivity at room temperature (rho(300 K) approximately 1 mOmega cm). Together with the low charge carrier concentration of 2.3 e(-)/unit cell at 300 K this is typical of a degenerate semiconductor. The lattice thermal conductivity is distinctly smaller than that of Ba(8)Ge(43)square(3), where the vacancies partially order, and smaller than those of Ba-Ni-Ge type-I clathrates without vacancies, suggesting that disordered vacancies efficiently scatter heat-transporting phonons. We provide evidence that the maximum value of the thermoelectric figure of merit reached in Ba(8)Ni(3.5)Ge(42.1)square(0.4), ZT(680 K) congruent with 0.21, can be further improved by adjusting the charge carrier concentration.
