Is the online learning good in the midst of Covid-19 Pandemic? The case of EFL learners

Abstract: The purpose of this study is to investigate the learners’ perception on online learning in the midst of a COVID-19 pandemic. This research applied qualitative method. The subject of this research are the learners of English study program of UKI Toraja. The instrument used is semi-structured interview. Thus the pandemic of covid-19, the researcher interviewed the learners by calling them by using WhatsApp application. A thematic analysis was employed in the current study. The study showed that the learners’ perception on online learning reveals that it is good in the midst of COVID-19 pandemic. They perceived online learning is very helpful in the middle of pandemic. This study not only report that online learning is good in the midst of COVID-19 pandemic but also spotted the light on the availability of internet access, financial issue, and online learning implementation. At the learners’ condition in terms of financial issue, they hope that lecturers make use of facilities such as free Messenger application in Online Learning System. In the light of the availability of internet access, they said that individual tasks are better to keep the distance physically due to pandemic, they need group tasks to help friends who do not have an internet pulse and access. About the implementation, they hope that material and assignment must be preceded by explanation. Thus, they recommended that Voice Note will be effectively used when giving instructions. It implied that the material and instruction implemented by the lecturer in the online learning were not easy to use.

Simple and rapid detection of Candida albicans DNA in serum by PCR for diagnosis of invasive candidiasis.

Abstract: A rapid and sensitive PCR assay for the detection of Candida albicans DNA in serum was established. DNA from human serum samples was purified using the QIAamp blood kit, which proved to be a fast and simple method for isolating minute amounts of Candida DNA from clinical specimens for diagnosis of invasive candidiasis. Universal primer sequences used in the PCR assay are derived from the internal transcribed spacer rRNA gene of fungi, whereas the biotinylated hybridization probe used in a DNA enzyme immunoassay (DEIA) binds specifically to C. albicans DNA. The sensitivity of this PCR-DEIA method is very high; the detection limit for genomic Candida DNA is one C. albicans genome per assay. Blood from uninfected and infected persons, ranging from healthy volunteers, patients with mucocutaneous infections, and patients at risk to develop a systemic Candida infection to patients with an established systemic candidiasis, was analyzed for the presence of C. albicans to diagnose fungal infection. Candida DNA could not be detected in sera of 16 culture-negative controls and from 11 nonsystemic candidal infections by PCR or DEIA. Blood cultures from patients at risk were all negative for Candida, whereas all blood cultures from systemic candidiasis patients were positive. However, Candida DNA could be detected by PCR and DEIA in the serum from three out of nine patients who were at risk for a systemic infection and in the serum of all seven patients who had already developed an invasive Candida infection. PCR is more sensitive than blood culture, since some of the patients at risk for invasive yeast infection, whose blood cultures were all negative for Candida, tested positive in the PCR amplification. These results indicate the potential value of PCR for detecting C. albicans in serum samples and for identifying patients at risk for invasive candidiasis.

Global guideline for the diagnosis and management of rare mould infections: an initiative of the European Confederation of Medical Mycology in cooperation with the International Society for Human and Animal Mycology and the American Society for Microbiology

Abstract: With increasing numbers of patients needing intensive care or who are immunosuppressed, infections caused by moulds other than Aspergillus spp or Mucorales are increasing. Although antifungal prophylaxis has shown effectiveness in preventing many invasive fungal infections, selective pressure has caused an increase of breakthrough infections caused by Fusarium, Lomentospora, and Scedosporium species, as well as by dematiaceous moulds, Rasamsonia, Schizophyllum, Scopulariopsis, Paecilomyces, Penicillium, Talaromyces and Purpureocillium species. Guidance on the complex multidisciplinary management of infections caused by these pathogens has the potential to improve prognosis. Management routes depend on the availability of diagnostic and therapeutic options. The present recommendations are part of the One World-One Guideline initiative to incorporate regional differences in the epidemiology and management of rare mould infections. Experts from 24 countries contributed their knowledge and analysed published evidence on the diagnosis and treatment of rare mould infections. This consensus document intends to provide practical guidance in clinical decision making by engaging physicians and scientists involved in various aspects of clinical management. Moreover, we identify areas of uncertainty and constraints in optimising this management.

Importance of resolving fungal nomenclature: The case of multiple pathogenic species in the Cryptococcus genus

Abstract: Cryptococcosis is a major fungal disease caused by members of the Cryptococcus gattii and Cryptococcus neoformans species complexes. After more than 15 years of molecular genetic and phenotypic studies and much debate, a proposal for a taxonomic revision was made. The two varieties within C. neoformans were raised to species level, and the same was done for five genotypes within C. gattii. In a recent perspective (K. J. Kwon-Chung et al., mSphere 2:e00357-16, 2017, https://doi.org/10.1128/mSphere.00357-16), it was argued that this taxonomic proposal was premature and without consensus in the community. Although the authors of the perspective recognized the existence of genetic diversity, they preferred the use of the informal nomenclature "C. neoformans species complex" and "C. gattii species complex." Here we highlight the advantage of recognizing these seven species, as ignoring these species will impede deciphering further biologically and clinically relevant differences between them, which may in turn delay future clinical advances.

Survey of laboratory practices for diagnosis of fungal infection in seven Asian countries: An Asia Fungal Working Group (AFWG) initiative.

Abstract: An online survey of mycology laboratories in seven Asian countries was conducted to assess the status, competence, and services available. Country representatives from the Asia Fungal Working Group (AFWG) contacted as many laboratories performing mycology diagnosis as possible in their respective countries, requesting that the laboratory heads complete the online survey. In total, 241 laboratories responded, including 71 in China, 104 in India, 11 in Indonesia, 26 in the Philippines, four in Singapore, 18 in Taiwan, and seven in Thailand. Overall, 129/241 (53.5%) surveyed mycology laboratories operate as separate designated mycology laboratories, 75/241 (31.1%) conduct regular formal staff training, 103/241 (42.7%) are accredited, and 88/157 (56.1%) participate in external quality assurance scheme (EQAS) programs. Microscopy and culture methods are available in nearly all laboratories, although few perform DNA sequencing (37/219; 16.9%) or use matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF MS) (27/219; 12.3%) for isolate identification. Antifungal susceptibility testing is performed in 142/241 (58.9%) laboratories, mainly for yeasts. The most commonly performed nonculture diagnostic is cryptococcal antigen testing (66 laboratories), followed by galactomannan testing (55), polymerase chain reaction (PCR) diagnosis (37), and beta-D-glucan testing (24). Therapeutic drug monitoring is conducted in 21 laboratories. There is almost no access to advanced diagnostic tests, like galactomannan, β-D-glucan, and PCR, in the surveyed laboratories in Indonesia, the Philippines, and Thailand. These results highlight the need for development of quality laboratories, accreditation and training of manpower in existing laboratories, and access to advanced non-culture-based diagnostic tests to facilitate the diagnosis of fungal infections in Asia.
