Abstract: The main objective of this study is to assess the mangrove biodiversity in response to environmental changes, specifically its relationship between environmental variables and mangrove species biodiversity by evaluating the indicators in terms of abundance, richness, and evenness, alongside an analysis using Canonical Correspondence Analysis. Mangrove forest plays a significant role that caters to potential services like reductions of atmospheric carbon and has been the center for conservation due to its high importance to marine ecology. Based on the findings of the study, it was revealed that the area located in Brgy. Peñaplata, Samal City, Philippines, seven mangrove species were identified, classified into four families: Avicennia alba, Avicennia marina, and Avicennia rumphiana in the Avicenniaceae family; Rhizophora apiculata, Rhizophora mucronata, and Rhizophora stylosa in the Rhizophoraceae family; and Sonneratia alba in the Lythraceae family. Rhizophora mucronata emerged as the most abundant species, comprising 35.5% of total individuals. Moreover, the area determined to have low diversity due to the dominance of Rhizophora mucronate and Avicennia alba, leading to an unbalanced ecosystem, except in plot 3, which showed a more balanced and diverse mangrove ecosystem. Overall, significant correlations with the use of CCA were found, highlighting the positive influence of pH, temperature, TDS, and conductivity on mangrove species patterns and distribution. The findings of this study could support shape strategies for conserving and safeguarding mangrove ecosystems in Samal City, and maybe throughout the Philippines.

Abstract: Objective: The objective of this study was to determine the clinical features and risk factors for hospital-associated pulmonary thromboembolism (HA-PTE) in Taizhou Hospital of Zhejiang Province. Methods: The clinical data of 513 pulmonary thromboembolism (PTE) patients who were admitted to Taizhou Hospital of Zhejiang Province in from January 1st, 2020, to December 31st, 2022, were retrospectively analyzed. The HA-PTE group and the community-associated PTE (CA-PTE) group were classified according to whether these disorders occurred during hospitalization or within a 90-day period of admission to the hospital (including inpatients with at least two days of hospitalization stay or a surgical procedure under or regional anesthesia). Differences in clinical features, risk factors and other indicators were also analyzed between the two groups. Results: A total of 513 patients with acute PTE were analyzed in the present study. Among them, 134 patients had HA-PTE, and 379 patients had CA-PTE. Patients in the HA-PTE group had less dyspnea or hemoptysis and more fever and chest pain. The all-cause mortality rate in the HA-PTE group was greater than that in the CA-PTE group, but it was not statistically significant. In comparison to community-acquired pulmonary thromboembolism (CA-PTE), long-term bed rest, active malignancy, lung infection, acute cerebral infarction, and fracture were observed as more prevalent risk factors in the hospital-acquired pulmonary thromboembolism (HA-PTE) group. Additionally, recent surgery (within one month post-operation) and central venous catheterization were identified as independent risk factors in the HA-PTE group. According to the subgroup analysis of the HA-PTE group, the all-cause mortality rate of patients who experienced HA-PTE in the hospital was lower than that of patients who experienced HA-PTE which in 90 days after admission (1.56% versus 2.85%, respectively); however, the difference was not statistically significant. Conclusion: More than half of the HA-PTE events were associated with recent hospitalization. HA-PTE and CA-PTE have different risk factors; when combined with different clinical symptoms, they have a higher incidence of HA-PTE occurring in the hospital. More attention should be given to inpatients to reduce the incidence of HA-PTE.
