Prescribing practices in the treatment of depression among psychiatrists in Oman.

OBJECTIVES: To examine the prescribing patterns of antidepressants among a sample of psychiatrists working in Oman and to compare these practices to the current evidence for prescribing specific antidepressant in particular clinical situations. METHODS: This retrospective cross sectional study. Massachusetts General Hospital Psychopharmacology Questionnaire, a 10-item questionnaire listing factors that might have influenced the choice of antidepressant medication, was sent to 83 psychiatrists working in governmental health sectors in Oman. The study was done from March to July 2019. RESULTS: A total number of 78 psychiatrists responded to the questionnaire. Of these, 44 of the psychiatrists (56.4%) believed that one type of antidepressant is more efficacious than others, while 74 psychiatrists (94.9%) indicated that selective serotonin reuptake inhibitors (SSRIs) were their first-line treatment preference. Mirtazapine was chosen as the most likely antidepressant to cause weight gain by two-thirds of the participants. For the treatment of anxious depression and depression with melancholic feature, SSRIs were the first choice of treatment for 64.1% and 7% of respondents, respectively. For depression with atypical features, 42.3% indicated that a monoamine oxidase inhibitor would be their first option. CONCLUSION: There is a discrepancy between the current antidepressant prescribing practices in Oman and empirical antidepressant-prescribing evidence, and this finding is consistent with previous studies.

Four years of monitoring for viral haemorrhagic septicaemia virus in marine waters around the United Kingdom.

Between 1995 and 1998, marine fish from around the coast of the UK were collected and samples analysed for viral haemorrhagic septicaemia virus (VHSV) using cell culture isolation methods. In 1997 and 1998 the samples were also analysed for VHSV by reverse transcription PCR (RT-PCR). A total of 1867 fish of 11 species were tested, but VHSV was isolated on only 1 occasion, from herring Clupea harengus, in 1996. However, despite VHSV not being isolated in 1997 and 1998, in both years samples of herring from the west and south coasts of England produced positive signals in the RT-PCR, and in 1997 cod from the east coast of England also produced positive signals in the RT-PCR. These results are believed to be true indications of the presence of VHSV nucleic acid in the fish. In 1997, birnaviruses from Serogroup B1 were isolated from herring (a previously unrecorded host for the virus) and cod Gadus morhua, and a birnavirus from Serogroup A2 was also isolated from cod. In 1998, an aquareovirus was isolated from haddock Melanogrammus aeglefinus, a previously unrecorded host for the virus.
