Analysis of antipsychotic drugs prescribing in incarcerated persons in a Serbian correctional facility.

PURPOSE: Prison settings have limited resources, and it is of particular interest to analyze which antipsychotics are commonly prescribed in these conditions and to determine the prevalence of the adverse effects. DESIGN/METHODOLOGY/APPROACH: A cross-sectional, epidemiological survey was used to measure the prevalence of antipsychotic prescribing among adult prisoners in Sremska Mitrovica Prison in 2020. FINDINGS: The prevalence of antipsychotic use was 7.58%. The most commonly prescribed antipsychotic was clozapine (45.36%), but also olanzapine, haloperidol and risperidone were prescribed. The incidence of extrapyramidal adverse effects was nonexistent and the metabolic parameters did not differ between participants using metabolic syndrome-inducing antipsychotics and those who were prescribed metabolically inert medications. The prescribed doses were lower compared with the recommended. RESEARCH LIMITATIONS/IMPLICATIONS: This research includes certain points that should be cautiously considered. First, the data were cross-sectional and the findings did not provide causal interpretations. Second, the data are from a single penitentiary institution, albeit the largest in the country; however, that may affect the generalizability of the findings. Third, because the included subjects were not hospitalized, some laboratory analyses were not available, according to the local regulations, and thus the prevalence of metabolic syndrome could not be precisely determined. PRACTICAL IMPLICATIONS: The prevalence of the antipsychotic use in prison environment is significantly higher than in general population. The most frequently prescribed antipsychotics are clozapine and olanzapine. The prevalence of adverse effects is rare, however, that is possibly due to low doses of the prescribed antipsychotics. The list of therapeutic options available to the incarcerated persons in this facility is also limited. The list of available antipsychotics does not include some atypical antipsychotics with more favorable safety and tolerability profile, such as aripiprazole or cariprazine. Long-acting antipsychotic injectables were also not available to these patients. Laboratory analyses are not regularly conducted and do not include some essential parameters such as lipid status or differential blood count. Low-dose antipsychotics for behavioral symptoms appears to be well tolerated under prison conditions where adherence is assured. It is effective during the prison stay but long-term effects, especially after release from prison, had not been studied. SOCIAL IMPLICATIONS: This paper advocates for better quality of health care in this correctional facility: more therapeutic options and better laboratory monitoring. The authors justify the use of clozapine in this settings due its benefits in reducing violence and aggression; however, further research would be necessary to clarify does the use of clozapine in incarcerated persons cause behavioral improvements that could result in shorter incarcerations, less recidivism and better quality of life. ORIGINALITY/VALUE: To the best of the authors' knowledge, this is the first insight of the antipsychotic prescribing practice in Serbia. There is very limited data on prisoners' health care, especially mental health care, in Balkan countries. The antipsychotic prescribing pattern in this sample is characterized with higher than expected clozapine use, but without expected adverse effects.

Pharmacology of repair after peripheral nerve injury.

Peripheral nerve injuries are common and present with a broad spectrum of symptoms, some of which may be the cause of life-long disabilities. The peripheral nerves show a far greater capacity for regeneration than those in the central nervous system, and the process of nerve regeneration resembles developmental processes to a certain degree. The regeneration of peripheral nerves does not always lead to a full functional recovery. That is why surgical methods are still the most reliable therapeutic options after injuries of peripheral nerves. However, there is an array of potential pharmacological options that could enhance the repair processes after surgery. This review gives a summary of the recent literature relevant to different classes of pharmacologically active substances that are used either as supplements or off-label as potential enhancers of peripheral nerve repair. Antioxidants, vitamins, calcium channel blockers, immunosuppressive drugs, growth factors, and neuroactive glycans are among the most researched in this field. More research is necessary to understand their mechanisms of action at the cellular and molecular level, and randomized clinical trials in order to establish their efficacy and safety, as well as possible synergistic or adverse interactions among them.

Chromatin Fractal Organization, Textural Patterns, and Circularity of Nuclear Envelope in Adrenal Zona Fasciculata Cells.

Despite previous research efforts in the fields of histology and cell physiology, the relationship between chromatin structural organization and nuclear shape remains unclear. The aim of this research was to test the existence and strength of correlations between mathematical parameters of chromatin microarchitecture and roundness of the nuclear envelope. On a sample of 240 nuclei of adrenal zona fasciculata cells stained using the DNA-specific Feulgen method, we quantified fractal parameters such as fractal dimension and lacunarity, as well as textural parameters such as angular second moment (ASM), entropy, inverse difference moment, contrast, and variance. Circularity of the nuclear envelope was determined from the nuclear area and perimeter. The results indicate that there is a statistically significant negative correlation between chromatin ASM and circularity. Moreover, there was a statistically significant positive correlation between chromatin fractal dimension and envelope circularity. This is the first study to demonstrate these relationships in adrenal tissue, and also one of the first studies to test the connection between circularity and fractal and gray-level co-occurrence matrix parameters in DNA-specific Feulgen stain. The results could be useful both as an addition to the current knowledge on chromatin/nuclear envelope interactions, and for design of future computer-assisted research software for evaluation of nuclear morphology.
