Indication for Y Chromosome Microdeletion Analysis in Infertile Men: Is a New Sperm Concentration Threshold Needed?

Urology 2020 Dec 6;146:113-117. Epub 2020 Oct 6.

Objective: To describe the prevalence of Y-chromosome deletions in patients with a sperm concentration of less than 5 million/mL. To also determine a new sperm threshold for Y-chromosome analysis in men with infertility.

Methods: A total of 3023 patients who had a semen concentration of less than 5 million/mL included in this retrospective study. All of these patients had a genetic evaluation, hormonal evaluation, and 2 abnormal semen analyses.

Results: Y-chromosome deletions were present in 116 (3.8 %) patients with sperm concentration <5 million/mL. The frequency of a Y-chromosome deletions was 6.8%, 1.0%, 0.15% in azoospermic men, in men with sperm concentrations of 0-1 million /mL, in men with sperm concentrations of 1-5 million/mL. Patients were divided into 2 groups regarding the determined new sperm threshold. The sensitivity and specificity of the Y-chromosome deletions test were 92.2.7% and 49.3 %, 99.1%, and 22.1% in patients with azoospermia and sperm concentrations <1 million/mL, respectively. If the sperm concentration thresholds of azoospermia or <1 million/mL, are applied, the number of tests decreased to 50.5% (1442 tests) and 23.1% (643 tests), respectively. Approximately $108,150 and $48,225 would be saved if the sperm thresholds were azoospermia and <1 million/mL, respectively CONCLUSION: The current threshold of sperm concentration for Y-chromosome deletions is controversial. The new proposed sperm threshold for genetic testing of 1 million/mL would increase sensitivity and more cost-effective compared to the current threshold.

Subjective Recovery in Patients with Schizophrenia and Related Factors.

Community Ment Health J 2020 08 10;56(6):1180-1187. Epub 2020 Apr 10.

Subjective recovery is a personally perceived recovery involving other factors beyond clinical recovery. This study aims at investigating the factors related to subjective recovery in patients with schizophrenia living in Turkey. This study assessed 120 clinically stable outpatients with schizophrenia or schizoaffective disorder using the clinical and psychosocial scales. Gender, type of the diagnosis of disease, and age of the illness onset were found to be correlated with the subjective recovery. Subjective recovery was significantly correlated with CGI-S (r = - 0.25), total PANSS score (r = - 0.29), global assessment of functioning (r = 0.27), social functioning (r = 0.43), internalized stigma (r = - 0.38), self-esteem (r = 0.56), depression (r = - 0.59), and hopelessness (r = - 0.55). Hopelessness and self-esteem were found to be predictive of the subjective recovery explaining 52% of the variance. It can be argued that efforts to promote hope and self-esteem contribute to the subjective recovery.
