The purpose was to investigate what effect an intervention of low-dose, high-frequency cardiopulmonary resuscitation (CPR) training with feedback for one month would have on professionals' subjective self-assessment skill of CPR.

This study had a quantitative approach. In total, 38 firefighters performed CPR for two minutes on a Resusci Anne QCPR. They then self-assessed their CPR through four multiple-choice questions regarding compression rate, depth, recoil and ventilation volume. After one month of low-dose, high-frequency training with visual feedback, the firefighters once more performed CPR and self-assessed their CPR.

With one month of low-dose, high-frequency training with visual feedback, the level of self-assessment was 87% (n = 33) correct self-assessment of compression rate, 95% (n = 36) correct self-assessment of compression depth, 68% (n = 26) correct self-assessment of recoil and 87% (n = 33) correct self-assessment of ventilations volume. The result shows a reduced number of firefighters who overestimate their ability to perform CPR.

With low-dose, high-frequency CPR training with visual feedback for a month, the firefighters develop a good ability to self-assess their CPR to be performed within the guidelines. By improving their ability to self-assess their CPR quality, firefighters can self-regulate their compression and ventilation quality.

The purpose of this paper is to investigate the effects of the intervention of low-dose, high-frequency cardiopulmonary resuscitation (CPR) training with feedback for firefighters for one month.

The study had a quantitative approach. Data were collected through an intervention by means of simulation. The data collection consisted of a pre- and post-assessment of 38 firefighter’s CPR performance.

There was a statistically significant improvement from pre- to post-assessment regarding participants’ compression rates. Compression depth increased statistically significantly to average 2 mm too deep in the group. Recoil decreased in the group with an average of 1 mm for the better. There was a statistically significant improvement in participants’ ventilation volume from pre- to post-assessment.

Prehospital staff such as firefighters, police, and ambulance perform CPR under less than optimal circumstances. It is therefore of the utmost importance that these professionals are trained in the best possible way. The result of this study shows that low-dose, high-frequency CPR training with an average of six training sessions per month improves ventilation volume, compression depth, rate, and recoil. This study concludes that objective feedback during training enhances the firefighters’ CPR skills which in turn also could be applied to police and ambulance CPR training.

Dynamics of population mutagenesis during 22 consecutive generations of animals, as well as genetic radioadaptation were studied in natural populations of small mammals (bank voles) under chronic low‐intensive irradiation due to the Chernobyl accident. The data obtained point to oppositely directed processes in irradiated populations: accumulation of mutations (genetic load of populations) and formation of genetic radioadaptation. It is suggested that the frequencies of genetic damages in populations could be higher in the absence of radioadaptation process. A relationship between the frequencies of cytogenetic injuries and low doses of radiation was revealed in animal generations studied. The non‐linear dose‐effect curves are most likely to be defined by the complicated microevolutionary processes in populations. The results obtained indicate the absence of genetic effect threshold of low dose radiation. Besides, they show that a dependence of cytogenetic effects on radiation low doses in series of irradiated generations cannot be revealed using linear equations.

In the past many scientists have published papers on hormesis, on molecular stress responses, and on the similia principle in homoeopathy. Very few, however, have stressed a common base of interdependence of these fields. Reviews the most important of these studies to demonstrate their evolution and their mutual importance. Furthermore, a multidisciplinary approach is chosen to demonstrate research into the beneficial effects of subharmful doses of toxicants administered in suboptimal conditions (such as in stressed or injured organisms and cells).

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.

A cross-sectional, epidemiological survey was used to measure the prevalence of antipsychotic prescribing among adult prisoners in Sremska Mitrovica Prison in 2020.

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.

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.

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.

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.

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.

Iron deficiency anaemia (IDA) is a common problem in pregnancy and may influence the health of both mother and child. The purpose of this paper is to discuss current prevention and treatment strategies for pregnancy IDA and describe alternative methods, such as food‐based approaches that may be another way forward.

A literature review was conducted to locate and summarise up‐to‐date published studies within the field.

There is good evidence that iron supplements may be used to prevent and treat IDA in pregnancy. However, there is much debate about “the optimal” dose to recommend. High doses may contribute to oxidative stress and cause gastrointestinal symptoms while there still remain problems with compliance, even for lower dose iron supplements. Encouraging the daily consumption of functional foods containing suitable levels of iron may therefore be an alternative way to improve pregnancy iron status.

There is a wealth of important studying the health implications of iron supplements in pregnancy. More work is needed to establish whether functional foods containing iron could be an alternative way to help improve iron status.

Most papers and research focus on supplement use as a preventative measure and treatment for IDA; few discuss other approaches.

The purpose of this paper is to explore the effects of low doses of caffeine (<3 mg/kg) on jumping performance using a meta-analysis.

The search for eligible studies was performed through six databases, with additional backward and forward citation tracking. A random-effects meta-analysis was performed to compare the effects of caffeine vs placebo on jump height. The methodological quality of the included studies was appraised using the physiotherapy evidence database checklist.

Eight studies were included in the review. They were classified as good or excellent methodological quality. The pooled number of participants across all studies was 203. Four studies provided caffeine in relative doses, ranging from 1 to 2 mg/kg. Four studies provided caffeine supplementation in absolute doses of 80, 150 or 200 mg. The meta-analysis found that caffeine ingestion increased vertical jump height (Cohen’s d: 0.21; 95% confidence interval: 0.10, 0.31; p < 0.001; +3.5%).

The present meta-analysis found that caffeine doses of ∼1 to 2 mg/kg enhance jumping height. The effects observed herein are similar to those with higher caffeine doses, which is relevant as low caffeine doses produce minimal side effects. For most individuals, a caffeine dose of ∼1 to 2 mg/kg is equivalent to an amount of caffeine in an energy drink, one to two cups of coffee, one to two pieces of caffeinated chewing gum or several cups of green tea.

The purpose of this paper is to examine the impact of supplement form and dosage level on consumers’ perceptions of dietary supplement efficacy.

The authors draw upon literature on dietary supplements and accessibility–diagnosticity theory to derive their hypotheses. Hypotheses are tested through two experiments that use a 2 (supplement form: single-ingredient [SI] vs multi-ingredient [MI]) × 2 (dosage level: low vs high) factorial design.

The findings show that consumers perceive that lower dose MI supplements are more effective than lower dose SI supplements, consistent with a “more is better” heuristic. In contrast, under high doses, the supplement form effect is insignificant; that is, MI and SI supplements are perceived to be comparable in terms of efficacy.

Dietary supplements are not regulated the same way as prescription drugs. Consumers often draw inferences about supplement efficacy based on their perceptions rather than objective evidence. This may leave consumers vulnerable to potentially harmful consequences. This research has implications for designing supplement marketing efforts and public policy, which could help consumers to make informed choices when purchasing dietary supplements.

A growing awareness of the importance of maintaining a healthy lifestyle has motivated consumers of all ages to consider alternative remedies, most notably using dietary supplements. Past research offers little insight into understanding consumer reactions to dietary supplement form such as SI and MI supplements and their dosage levels. The studies reported here address this gap in research. Public policy and marketing implications are also discussed.

The purpose of this study was to determine the effects of whole oat, oat bran and refined oat incorporation in a high-fat diet (HFD) on cardio-metabolic risk biomarkers in rats with type 2 diabetes mellitus (T2DM).

T2DM was induced by feeding male rats with an HFD for 10 weeks, followed by a low dose of streptozotocin. T2DM rats were then divided into four homogeneous groups. Three groups consumed an HFD containing 45 per cent (g/100 g diet) whole oat, oat bran or refined oat. The fourth untreated group (control) received the HFD.

The results showed that whole oat and oat bran, compared with refined oat and control, effectively reduced food intake (p < 0.007), arterial blood pressure (p = 0.0001), glycemia (p < 0.001), insulinemia (p < 0.01), glycosylated haemoglobin (p < 0.001) as well as homeostasis insulin resistance (HOMA-IR) (p < 0.001). They also improved blood lipid levels and reverse cholesterol transport by reducing serum total cholesterol (p = 0.0001), triacylglycerols (p < 0.05), very-low- (p = 0.0001) and low-density lipoproteins cholesterol contents (p < 0.02) increasing lipids (p < 0.002) and cholesterol excretion (p = 0.0001), and high-density lipoprotein cholesteryl esters (HDL₂-CE) concentrations (p = 0.0001) and stimulating lecithin: cholesterol acyltransferase (LCAT) activity (p = 0.0001). Moreover, they attenuated lipid peroxidation by increasing paraoxonase-1 (PON-1) atheroprotective activity (p < 0.05).

In T2DM rats, whole oat and particularly, its bran incorporated into an HFD improves arterial blood pressure, glycemic balance and lipid metabolic pathway by reducing hypertriglyceridemia and hypercholesterolemia and increasing atheroprotective activities of LCAT and PON-1. In contrast, refined oat accentuates the risk factors associated with diabetes.
