Detection of the SARS-CoV-2 Omicron Variant in COVID-19 Patients from South Tangerang Using SNP-Probes S371L and K417N

The COVID-19 pandemic caused by the SARS-CoV-2 virus has posed a global challenge. Experts from various branches of science have endeavoured to find solutions to control its spread, one of which has been the quick and precise detection of the virus and its variants in patients. This study aimed to detect the presence of SARS-CoV-2, notably the rapidly spreading Omicron variant, using the spike (S)-gene target failure (SGTF) and S-gene target positive (SGTP) with the principle of the single nucleotide polymorphism (SNP)-probe test. Our descriptive experimental approach detected Omicron variants with the SNP-probe technique using samples of SARS-CoV-2 patients and controls. The probes were designed to recognize the nucleotide code of the amino acids in positions 371 and 417 of SARS-CoV-2. The existence of variants was monitored by the presence or absence of a fluorescence signal, which was translated into a sigmoidal graph using a real-time (RT)-PCR machine. One hundred and twelve samples that had tested positive for SARS-CoV-2 and the Omicron variant using a registered commercial kit showed a similar result to our in-house-developed SNP-probe 371 and 417 assays. The results of this study indicate that the SNP-probe we designed can be used in the detection of the SARS-CoV-2 Omicron variant

The Identification of the SARS-CoV-2 Whole Genome: Nine Cases Among Patients in Banten Province, Indonesia

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the strain of virus that causes coronavirus disease 2019 (COVID-19), the respiratory illness responsible for the current pandemic. Viral genome sequencing has been widely applied during outbreaks to study the relatedness of this virus to other viruses, its transmission mode, pace, evolution and geographical spread, and also its adaptation to human hosts. To date, more than 90,000 SARS-CoV-2 genome sequences have been uploaded to the GISAID database. The availability of sequencing data along with clinical and geographical data may be useful for epidemiological investigations. In this study, we aimed to analyse the genetic background of SARS-CoV-2 from patients in Indonesia by whole genome sequencing. We examined nine samples from COVID-19 patients with RT-PCR cycle threshold (Ct) of less than 25 using ARTIC Network protocols for Oxford Nanopore’s Gridi On sequencer. The analytical methods were based on the ARTIC multiplex PCR sequencing protocol for COVID-19. In this study, we found that several genetic variants within the nine COVID-19 patient samples. We identified a mutation at position 614 P323L mutation in the ORF1ab gene often found in our severe patient samples. The number of SNPs and their location within the SARS-CoV-2 genome seems to vary. This diversity might be responsible for the virulence of the virus and its clinical manifestation

Suicidal thoughts, attempts and motives among university students in 12 Muslim-majority countries

There is a scarcity of research on suicidal phenomena in the Muslim world. Therefore, this study aimed at investigating the self-reported prevalence of suicidal thoughts, attempts and motives in 12 Muslim countries. A total of 8417 (54.4% women) university students were surveyed by means of a self-report questionnaire. Overall, 22% of the participants reported suicidal ideation and 8.6% reported attempting suicide. The odds of suicidal thoughts were elevated in Azerbaijan, Indonesia and Saudi Arabia, while reduced ORs were recorded in Egypt, Jordan, Lebanon and Malaysia. While odds of suicide attempts were high in Azerbaijan, Palestine and Saudi Arabia reduced odds ratios (OR) were detected in Indonesia, Iran, Jordan, Lebanon, Malaysia and Tunisia. Taking drugs and using a sharp instrument were the two most frequently used methods to attempt suicide. Only 32.7% of attempts required medical attention. Escape motives were endorsed more than social motives by participants who attempted suicide. Suicidal behaviors were more frequent in women than in men. Compered to men, fewer attempts by women required medical attention. Moreover, our results show that making suicide illegal does not reduce the frequency of suicidal behavior. Results from this comparative study show that suicidal thoughts and attempts are frequent events in young adults in countries where religious scripture explicitly prohibit suicide and the frequencies of nonfatal suicidal behavior show large variation in nations adhering to the same religion
