Psychiatric treatment seeking and psychosocial impairment among young adults with depression

BACKGROUND: We report data on 1-year prevalence and comorbidity of depression, related impairment, treatment need, and psychiatric treatment among young adults. METHODS: A sample of young urban adults (n=245) mean age 21.8 years was screened from a baseline population of 706 high-school students and given a semistructured clinical interview to evaluate 12-month prevalence of depression, psychosocial functioning according to DSM-IV GAF scale, need for psychiatric treatment, and use of mental health services. RESULTS: One in 10 young adults suffered from depression with associated psychosocial impairment, the female-to-male-ratio being approximately 2:1. Most depressive disorders were comorbid with other DSM-IV disorders, depression usually occurring secondary to other disorders. Comorbidity was related to impairment, treatment need, and treatment contacts. Less than half of the depressed young adults had ever contacted mental health services, and less than one-third reported treatment contacts during the index episode. Males were less likely than females to report previous treatment contacts or intention to refer to mental health services for their problems, but treatment contacts during the index episode were reported equally often by both sexes. CONCLUSIONS: A minority of the severely depressed young adults with associated impairment had sought treatment. Except for subjects with dysthymia, no gender difference emerged in treatment contact rates during the 12-month depression episode. Comorbidity showed important clinical implications by its relation to severity of depression and treatment contacts.     

Cognitive functioning in substance abuse and dependence: a population-based study of young adults

Aims   To investigate whether substance use disorders (SUDs) are associated with verbal intellectual ability, psychomotor processing speed, verbal and visual working memory, executive function and verbal learning in young adults, and to study the associations of SUD characteristics with cognitive performance.
Participants   A population-based sample ( n  = 466) of young Finnish adults aged 21–35 years.
Measurements   Diagnostic assessment was based on all available information from a structured psychiatric interview (SCID-I) and in- and out-patient medical records. Established neuropsychological tests were used in the cognitive assessment. Confounding factors included in the analyses were comorbid psychiatric disorders and risk factors for SUDs, representing behavioural and affective factors, parental factors, early initiation of substance use and education-related factors.
Findings   Adjusted for age and gender, life-time DSM-IV SUD was associated with poorer verbal intellectual ability, as measured with the Wechsler Adult Intelligence Scale–Revised (WAIS-R) vocabulary subtest, and slower psychomotor processing, as measured with the WAIS-R digit symbol subtest. Poorer verbal intellectual ability was accounted for by parental and own low basic education, whereas the association with slower psychomotor processing remained after adjustment for SUD risk factors. Poorer verbal intellectual ability was related to substance abuse rather than dependence. Other SUD characteristics were not associated with cognition.
Conclusions   Poorer verbal intellectual ability and less efficient psychomotor processing are associated with life-time alcohol and other substance use disorders in young adulthood. Poorer verbal intellectual ability seems to be related to parental and own low basic education, whereas slower psychomotor processing is associated with SUD independently of risk factors.     

Loss of cutaneous microbial diversity during first 3 weeks of life in very low birthweight infants

Neonatal sepsis (NS) is a frequent problem in neonatal intensive care, especially in preterm and very low birthweight (VLBW) infants. The objective of the study was to characterize the cutaneous bacterial microbiome in VLBW infants treated in the neonatal intensive care unit (NICU). Non‐invasive skin microbiome specimens were taken repeatedly from 12 VLBW infants during treatment in NICU starting on the first day of life. All infants received benzylpenicillin and netilmicin during the first 1‐5 postnatal days. Samples were also collected from incubators. High cutaneous microbial diversity was present at birth in 11 of 12 of the infants, but the diversity decreased substantially after the first weeks of life in all infants regardless of their infection status. After the loss of diversity, one Staphylococcus operational taxonomic unit dominated the skin microbiome. Recovery of microbial diversity was seen in six of 12 neonates. The microbiome of incubators showed typical environmental bacterial genera. Maternal antibiotic treatment, the aetiology of the preterm birth or being born by C‐section did not appear to affect the diversity of skin microbiota at birth, and no correlation was found between cutaneous microbiome and NS.     

Depressive symptoms in adolescence as predictors of early adulthood depressive disorders and maladjustment

OBJECTIVE: The authors examined the association between self-reported depressive symptoms in adolescence and mental well-being in early adulthood. METHOD: A questionnaire assessing psychosocial well-being was given to a group of subjects (N=651) in their last 3 years of high school (mean age=16.8 years) and again when these subjects reached early adulthood (mean age=21.8 years). Diagnostic interview data were obtained from a subgroup of the young adults (N=245). Adolescents' depressive symptoms were analyzed in relation to their early adulthood mental health outcome data. RESULTS: Depressive symptoms in adolescence predicted early adulthood depressive disorders (major depression and dysthymia), comorbidity, psychosocial impairment, and problem drinking. CONCLUSIONS: Depressive symptoms in adolescence deserve attention as a potential risk for early adulthood mental disorders.     

Andrology: Epididymal sperm aspiration and use of donor spermatozoa when necessary for in-vitro fertilization, and vasoepididymostomy: an acceptable combination in the treatment of obstructive azoospermia

Infertility due to obstructive azoospermia in 24 men was treatedwith a combination of scrotal exploration, microsurgical spermaspiration and vasoepididymostomy, at the same operation. In-vitrofertilization (IVF) and embryo transfer were performed usingepididymal spermatozoa. Donor spermatozoa were used if no motileepididymal spermatozoa were obtained. With this combination,emotionally and economically acceptable pregnancy rates wereachieved: 24% per aspiration, 43% per embryo transfer, and 25%per couple. One twin pregnancy resulting in the birth of twohealthy female infants and one ongoing twin pregnancy were achievedwith epididymal spermatozoa; four pregnancies (one twin, twosingletons, one abortion) were achieved with donor spermatozoa.     

Enumeration and isolation of cpe-positive Clostridium perfringens spores from feces

A hydrophobic grid membrane filter-colony hybridization (HGMF-CH) method for the enumeration and isolation of cpe gene-carrying (cpe-positive) Clostridium perfringens spores from feces was developed. A 425-bp DNA probe specific for the cpe gene was sensitive and specific when tested with bacterial DNA and pure cultures. The enumeration of cpe-positive C. perfringens by the HGMF-CH method proved to be as sensitive as nested PCR combined with the most-probable number technique when tested with fecal samples from healthy individuals. With the aid of the HGMF-CH method, positive hybridization signals were detected from two out of seven fecal samples obtained from healthy individuals. Furthermore, cpe-positive C. perfringens was successfully isolated from both of these samples. The detection of cpe-positive C. perfringens by the HGMF-CH method is dependent on the ratio of cpe-positive C. perfringens colonies to total C. perfringens colonies growing on the HGMF-tryptose-sulfite-cycloserine plate. cpe-positive C. perfringens could be isolated if the ratio of cpe-positive C. perfringens spores to total C. perfringens spores was 6 x 10(-5) or higher. The HGMF-CH method provides an aid in the investigation of fecal samples of patients suffering from food poisoning or other diseases caused by cpe-positive C. perfringens. The method also offers a new approach in the investigation of the epidemiology of cpe-positive C. perfringens strains.
