Background and objectives: Extemporaneous preparations are pharmaceutical preparations individually prepared for a specific patient or patient group, but also high-risk products accompanied by doubts regarding their safety and quality. Legislation regulating the compounding of extemporaneous preparations is not harmonized among European countries. This problem is partially resolved by Resolution CM/Res(2016)1 on quality and safety assurance requirements for medicinal products prepared in pharmacies for the special needs of patients. ⋯ Most of the paragraphs of the resolution are described in Latvian regulatory enactments only partially. Conclusions: The total number of compounding pharmacies evidence that the service is needed. Latvian example highlights a necessity for European Union countries to compare their national legislation with the requirements of the resolution's last version and, if necessary, implement relevant amendments.

Exercise-associated hyponatremia (EAH) is defined as a plasma sodium concentration of <135 mmol/L during or after endurance and ultra-endurance performance and was first described by Timothy Noakes when observed in ultra-marathoners competing in the Comrades Marathon in South Africa in the mid-1980s. It is well-established that a decrease in plasma sodium concentration <135 mmol/L occurs with excessive fluid intake. Clinically, a mild hyponatremia will lead to no or very unspecific symptoms. ⋯ The prevalence of EAH depends on the duration of an endurance performance (i.e., low in marathon running, high to very high in ultra-marathon running), the sports discipline (i.e., rather rare in cycling, more frequent in running and triathlon, and very frequent in swimming), sex (i.e., increased in women with several reported deaths), the ambient temperature (i.e., very high in hot temperatures) and the country where competition takes place (i.e., very common in the USA, very little in Europe, practically never in Africa, Asia, and Oceania). A possible explanation for the increased prevalence of EAH in women could be the so-called Varon-Ayus syndrome with severe hyponatremia, lung and cerebral edema, which was first observed in marathon runners. Regarding the race location, races in Europe seemed to be held under rather moderate conditions whereas races held in the USA were often performed under thermally stressing conditions (i.e., greater heat or greater cold).

Background and objectives: In healthy individuals, autonomic alterations are associated with the aggregation of cardiovascular risk factors. However, in individuals with type 1 diabetes, who are known to present autonomic alterations, mainly characterized by a reduction in parasympathetic modulation, these associations have not yet been investigated. We assess whether the aggregation of cardiovascular risk factors influences parasympathetic indices of heart rate variability in young people with type 1 diabetes. ⋯ Data collection was carried out in 2014 and analyzed in 2017. Results: Individuals with two aggregate risk factors present a reduction in the values of the indices that reflect parasympathetic autonomic modulation compared to individuals without the risk factors analyzed, regardless of sex and age. Conclusion: In young people with type 1 diabetes, the aggregation of cardiovascular risk factors is associated with parasympathetic autonomic impairment.

Background: Metabolic syndrome (MetS) influences the autonomic modulation, increasing the risk of cardiovascular events, which demands the identification of effective treatments for this population. Considering this, the study has the objective of evaluating the effects of periodized aerobic interval training (AIT) on geometrical methods of heart rate variability (HRV) on individuals with MetS. Methods: 52 individuals with MetS were considered for analysis. ⋯ Significant differences were not observed for triangular interpolation of normal heartbeats interval histogram (TINN, -4.05 ± 17.38 vs. 25.52 ± 17.03) and SD1/SD2 ratio (0.03 ± 0.02 vs. 0.00 ± 0.02). Qualitative analysis of the Poincaré plot identified increase on dispersion of both short and long-term intervals between successive heartbeats (RR interval) on AITG after the AIT program. Conclusion: geometric indices of HRV suggest an increase in cardiac autonomic modulation in individuals with MetS after 16 weeks of periodized AIT.

Case Reports
A Rare Consequence after Shoulder Dislocation in a Professional Cyclist: A Case Report.
Background: Cycling is a popular source of recreation and physical activity for children and adults. With regard to the total number of sports injuries, cycling has the highest absolute number of injuries per year in the United States population. Cycling injuries can be classified into bicycle contact, traumatic, or overuse injuries. ⋯ Following the second cycle of medication assumption, the patient was able to continue physiotherapy treatment and was referred to the orthopedic specialist to proceed with shoulder stabilization surgery. Discussion and conclusion: Currently, the diagnosis of this unusual clinical condition is still unclear. It is a shared opinion of the authors that the trauma during the past bicycle race awakened an underlying psychological problem of the patient that resulted in a clinical condition of weakness of all the structures of the shoulder, such that these spasms could result in multiple multidirectional dislocations.
