    BACKGROUND: The incidence of postsurgical venous thromboembolism is thought to be low in Asian ethnic populations.

    OBJECTIVE: We studied the incidence of deep-vein thrombosis (DVT) in Asian patients undergoing major orthopedic surgery of the lower limbs.

    PATIENTS/METHODS: We performed a prospective epidemiological study in 19 centers across Asia (China, Indonesia, South Korea, Malaysia, Philippines, Taiwan, and Thailand) in patients undergoing elective total hip replacement (THR), total knee replacement (TKR) or hip fracture surgery (HFS) without pharmacological thromboprophylaxis. The primary endpoint was the rate of DVT of the lower limbs documented objectively with bilateral ascending venography performed 6-10 days after surgery using a standardized technique and evaluated by a central adjudication committee unaware of local interpretation.

    RESULTS: Overall, of 837 Asian patients screened for this survey, 407 (48.6%, aged 20-99 years) undergoing THR (n = 175), TKR (n = 136) or HFS (n = 96) were recruited in 19 centers. DVT was diagnosed in 121 of 295 evaluable patients [41.0%, (95% confidence interval (CI): 35.4-46.7)]. Proximal DVT was found in 30 patients [10.2% (7.0-14.2)]. Total DVT and proximal DVT rates were highest in TKR patients (58.1% and 17.1%, respectively), followed by HFS patients (42.0% and 7.2%, respectively), then THR patients (25.6% and 5.8%, respectively). DVT was more frequent in female patients aged at least 65 years. Pulmonary embolism was clinically suspected in 10 of 407 patients (2.5%) and objectively confirmed in two (0.5%).

    CONCLUSIONS: The rate of venographic thrombosis in the absence of thromboprophylaxis after major joint surgery in Asian patients is similar to that previously reported in patients in Western countries.

    Snake gourd (Trichosanthes cucumerina L.), an annual climbing plant belonging to the family of Cucurbitaceae, is native to Southeast Asia countries, e.g., India, Pakistan, Malaysia, China, and Indonesia. It is commonly consumed as a vegetable and also used as a traditional herbal medicine due to the antidiabetic, anti-inflammatory, antibacterial, hepatoprotective, and cytotoxic activities (Devi 2017). In September 2020, phytoplasma-induced disease symptoms such as little leaf, yellowing, phyllody, virescence, and witches' broom were observed on snake gourd in Yunlin County, Taiwan. The cross-sectional examination of the symptomatic plant by transmission electron microscopy showed typical phytoplasma-like pleomorphic bodies with spherical, oval and tubular shapes in sieve elements. Further examination by nested PCR revealed that a 1.2 kb DNA fragment for 16S rRNA gene was only amplified from symptomatic leaf of snake gourd using the phytoplasma universal primer pairs P1/P7 followed by R16F2n/R16R2. BLAST and iPhyClassifier (https://plantpathology.ba.ars.usda.gov/cgi-bin/resource/iphyclassifier.cgi) analyses on the amplified DNA fragment (accession no. MW309142) revealed that it shares 100% identity with that of GenBank accession NZ_AMWZ01000008 (complement [31109 to 32640]) of peanut witches' broom (PnWB) phytoplasma, a 'Candidatus phytoplasma aurantifolia'-related strain (Firrao et al. 2004), and could be classified into the 16SrII-V subgroup. Samples examined by nested PCR were further characterized by western blotting using the polyclonal antibody raised against the Imp of PnWB phytoplasma (Chien et al. 2020a, b). An expected signal of 19 kDa specific for Imp was only detected in the symptomatic snake gourd, but not in healthy snake gourd. Since the disease symptoms caused by phytoplasma infection are highly dependent on the secreted effectors (Namba 2019), phyllogen gene that is responsible for phyllody and virescence symptoms was amplified from symptomatic snake gourd by PCR. BLAST analysis revealed that phyllogen identified in snake gourd is identical with that of PnWB phytoplasma. In Taiwan, species of family Cucurbitaceae such as loofah, bitter gourd, and pumpkin are commonly infected by 16SrVIII phytoplasma (Davis 2017). In this study, we report for the first time that snake gourd, a species of family Cucurbitaceae, was infected by 16SrII-V PnWB phytoplasma in Taiwan.
