Significant improvement of risperidone-induced retrograde ejaculation on drug holidays: a case report

Risperidone, which is one of the most commonly prescribed second-generation antipsychotics can cause several sexual adverse effects. To date, research on the sexual side effects of risperidone has been mostly restricted to symptoms of decreased libido, erectile dysfunction and delayed ejaculation and far too little attention has been paid to risperidone associated retrograde ejaculation. What is not clear is that whether this side effect appears in a dose-dependent manner and whether structured treatment interruptions/drug holidays can diminish sexual adverse effects without a reduction in treatment efficacy. Another question is whether concurrent use of opiates and risperidone can increase the risk of retrograde ejaculation due to their anticholinergic and adrenergic blocking properties. Here we describe a case of a 30-year-old male with schizophrenia and opium dependence who developed risperidone-induced retrograde ejaculation; however, the ejaculatory dysfunction improved significantly on drug holidays. This is the first report on the use of structured treatment interruptions in the management of risperidone-induced retrograde ejaculation. © 2019, © 2019 The Author(s).

Mycobiota and aflatoxin B1 contamination of rainbow trout (Oncorhinchus mykiss) feed with emphasis to Aspergillus section Flavi

In the present study, mycobiota and natural occurrence of aflatoxin B1 (AFB1) in pellet feed and feed ingredients used in a feed manufacturing plant for rainbow trout nutrition was investigated. The samples were cultured on the standard isolation media for 2 weeks at 28 ºC. Identification of fungal isolates was implemented based on the macro- and microscopic morphological criteria. AFB1 was detected using high performance liquid chromatography (HPLC). Based on the results obtained, a total of 109 fungal isolates were identified of which Aspergillus was the prominent genus (57.0%), followed by Penicillium (12.84%), Absidia (11.01%) and Pseudallscheria (10.10%). The most frequent Aspergillus species was A. flavus (60.66%) isolated from all feed ingredients as well as pellet feed. Among 37 A. flavus isolates, 19 (51.35%) were able to produce AFB1 on YES broth in the range of 10.2 to 612.8 µg/g fungal dry weight. HPLC analysis of trout feed showed that pellet feed and all feed ingredients tested except gluten were contaminated with different levels of AFB1 in the range of 1.83 to 67.35 µg/kg. Unacceptable levels of AFB1 were reported for feed including soybean, fish meal and wheat. These results indicate the importance of AF contamination of trout feed in amounts higher than the acceptable level as a risk factor for fish farming production

Management of attention deficit hyperactivity disorder in children and adolescents: A national clinical guideline

One of the best approaches for evidence-based care is providing and using the guidelines. Observing these guidelines results in a better quality of health care, decreased unnecessary or harmful interventions, lower health costs, and an increase in patients� satisfaction. Management of Attention Deficit Hyperactivity Disorder (ADHD)-1 in children and adolescents is a guideline published after 6 years of research and review of resources in the domain of treatment of ADHD. A research team formed in Iran University of Medical Sciences provided this guideline by addressing reliable references and observing a scientific approach. This guideline is provided with respect to the present resources for the standard treatment of ADHD in our country. To prepare this guideline, this research team considered the most recent and strict version of the writing method in the treatment section of Health, Treatment, and Education Ministry. Although the present guideline has some shortcomings, it is a turning point in the history of the development of health care. It presents a systematic approach in the treatment of such disorder, one of the most prevalent disorders in child psychiatry. The colleagues and treatment centers can help such an issue by applying this guideline. © 2020, Iran University of Medical Sciences. All rights reserved

Prevalence of Dementia Among Older Patients: A Hospital-Based Study in Iran

Background: Dementia constitutes a public health hazard in developing countries. The aim of this study was to evaluate the prevalence of dementia and its associated factors in older hospitalized patients. Methods: The participants of this cross-sectional study consisted of older patients admitted to medical wards in Rasoul-e Akram hospital in Tehran, Iran. Mini-Mental State Examination, Mini-Cog test, Geriatric Depression Scale, Activities of Daily Living-Instrumental Activities of Daily Living (ADL-IADL) scale, and socioeconomic questionnaires were used. Results: A total of 205 elderly inpatients were included. The mean age was 71.33 ± 7.35 years; 63.4 of the participants had normal cognitive function, while 36.6 had some degree of cognitive impairment. There was a statistically significant relationship between gender, age, number of children, and occupation and the prevalence of dementia. Conclusion: Appropriate cognitive screening of older patients upon admission to hospitals could help identify potential adverse events and enhance the quality of care for patients with comorbid dementia. © The Author(s) 2019

Validity and reliability of the Persian version of �drug-related knowledge and attitude questionnaire� among Iranian medical students

Background: Promoting drug-related knowledge and improving relevant attitudes among students are of crucial importance toward the prevention of drug misuse. Objective: This study aimed to assess the validity and reliability of the �drug-related knowledge and attitude questionnaire� among Iranian medical students. Methods: The participants of this cross-sectional study were students of Iran University of Medical Sciences. The �drug-related knowledge and attitude questionnaire� and a socio-demographic questionnaire were used to gather the data. Content validity was assessed by a panel of 11 experts, and face validity was evaluated by 10 participating students. Item-total correlation and Cronbach�s alpha coefficients were used as internal consistency estimates. Results: The face and content validity of the questionnaire were satisfactory. The overall content validity index was.82. Cronbach�s alpha was.679, indicating an acceptable degree of internal consistency and homogeneity between the items. Overall, most of the students had adequate knowledge about the harmful effects of addictive substances (48.11 ± 3.26). Conclusions: The �drug-related knowledge and attitude questionnaire� has favorable validity and reliability to assess the knowledge and attitude of Iranian students toward drug misuse and may be used in clinical and epidemiological studies. Besides, our findings can provide a suitable starting point for the implementation of effective psychoeducational interventions aimed at the improvement of the students� knowledge and attitudes toward drug misuse. © 2020, © 2020 Taylor & Francis Group, LLC

De lokale samenleving: een integratiekader én een interventiekader?

Caregiving for dependent older adults with dementia has become an important public health issue. However, not much is known about the caregiver experience for caregivers of patients with dementia in Iran. This study was designed to examine the relationship between variables pertaining to primary caregivers and patients and the level of perceived caregiver burden. The participants of this cross-sectional study were 60 caregiver and care-recipient pairs presented to Rasoul-e Akram hospital and Brain and Cognition Clinic, in Tehran, Iran. A sociodemographic questionnaire, the Zarit Caregiver Burden Interview (ZBI), the General health questionnaire-28 (GHQ-28), the NEO Five-Factor Inventory (NEO-FFI), the Spiritual Well-Being Scale (SWBS), the Neuropsychiatric Inventory (NPI), and the Mini-Mental State Examination (MMSE) were used. Descriptive statistics, correlation coefficients, T-test, and multiple linear regression analyses were used in this study. Years of caregiving, hours of caregiving/week, total and subscale GHQ-28 scores, existential well-being subscale score on SWBS, and total NPI score were found to be significantly associated with the level of caregiving burden (p < 0.05). In addition, among the caregivers� personality traits, neuroticism and agreeableness predicted caregiver burden. Other sociodemographic factors and MMSE scores were not found to be significantly related to caregiver burden. A better understanding of the indicators of caregiver burden can help physicians, policy makers, and mental health managers to tailor the most appropriate preventative and remedial interventions for family caregivers. © 2020 Taylor & Francis Group, LLC
