Key lessons learnt from COVID-19 intra-action reviews in the Republic of Moldova, Montenegro, Kosovo and North Macedonia 2020-2021: a qualitative study.

OBJECTIVES: Our study described how the WHO intra-action review (IAR) methodology was operationalised and customised in three Western Balkan countries and territories and the Republic of Moldova and analysed the common key findings to inform analyses of the lessons learnt from the pandemic response. DESIGN: We extracted data from the respective IAR reports and performed a qualitative thematic content analysis to identify common (between countries and territories) and cross-cutting (across the response pillars) themes on best practices, challenges and priority actions. The analysis involved three stages, namely: extraction of data, initial identification of emerging themes and review and definition of the themes. SETTING: IARs were conducted in the Republic of Moldova, Montenegro, Kosovo and the Republic of North Macedonia between December 2020 and November 2021. The IARs were conducted at different time points relative to the respective pandemic trajectories (14-day incidence rate ranging from 23 to 495 per 100 000). RESULTS: Case management was reviewed in all the IARs, while the infection prevention and control, surveillance and country-level coordination pillars were reviewed in three countries. The thematic content analysis identified four common and cross-cutting best practices, seven challenges and six priority recommendations. Recommendations included investing in sustainable human resources and technical capacities developed during the pandemic, providing continuous capacity-building and training (with regular simulation exercises), updating legislation, improving communication between healthcare providers at all levels of healthcare and enhancing digitalisation of health information systems. CONCLUSIONS: The IARs provided an opportunity for continuous collective reflection and learning with multisectoral engagement. They also offered an opportunity to review public health emergency preparedness and response functions in general, thereby contributing to generic health systems strengthening and resilience beyond COVID-19. However, success in strengthening the response and preparedness requires leadership and resource allocation, prioritisation and commitment by the countries and territories themselves.

Half of expectant women in Montenegro show iodine deficiency, indicating that supplementation during pregnancy is necessary.

OBJECTIVE: In this study, iodine level in pregnant women of Montenegro and their needs for supplementation were investigated. METHODS: A urinary iodine concentration (UIC) study of 326 pregnant women between September and December 2017 in three regions of Montenegro was performed. UIC was related to creatinine (UI/Cr ratio). RESULTS: The median UIC (133 ± 5 µg/L) was indicative of iodine deficiency, as the WHO recommended UIC is 150-249 µg/L. The UI/Cr ratio (160 ± 6 µg/g creatinine) was just above the WHO/UNICEF/IGN recommendation. Approximately 50% of the surveyed women had a lower UIC than that recommended. CONCLUSION: Iodine deficiency is present in pregnant women in Montenegro. Monitoring the UIC during routine analyses in pregnant women in Montenegro is recommended, along with iodine supplementation for individuals that need it.

New bioelectrical impedance analysis equations for children and adolescents based on the deuterium dilution technique.

BACKGROUND AND AIMS: Body composition in childhood is not only a marker of the prevalence of obesity, but it can also be used to assess associated metabolic complications. Bioelectrical impedance analysis (BIA) shows promise as an easy to use, rapid, and non-invasive tool to evaluate body composition. The objectives of this study were to: (a) develop BIA prediction equations to estimate total body water (TBW) and fat-free mass (FFM) in European children and early adolescents and to validate the analysis with the deuterium dilution as the reference technique and (b) compare our results with previously published paediatric BIA equations. METHODS: The cohort included 266 healthy children and adolescents between 7 and 14 years of age, 46% girls, in five European countries: Bosnia and Herzegovina, Latvia, Montenegro, North Macedonia, and Portugal. TBW and FFM were the target variables in the developed regression models. For model development, the dataset was randomly split into training and test sets, in 70:30 ratio, respectively. Model tuning was performed with 10-fold cross-validation that confirmed the unbiased estimate of its performance. The final regression models were retrained on the whole dataset. RESULTS: Cross-validated regression models were developed using resistance index, weight, and sex as the optimal predictors. The new prediction equations explained 87% variability in both TBW and FFM. Limits of agreement between BIA and reference values, were within ±17% of the mean, (-3.4, 3.7) and (-4.5, 4.8) kg for TBW and FFM, respectively. BIA FFM and TBW estimates were within one standard deviation for approximately 83% of the children. BIA prediction equations underestimated TBW and FFM by 0.2 kg and 0.1 kg respectively with no proportional bias and comparable accuracy among different BMI-for-age subgroups. Comparison with predictive equations from published studies revealed varying discrepancy rates with the deuterium dilution measurements, with only two being equivalent to the equations developed in this study. CONCLUSIONS: The small difference between deuterium dilution and BIA measurements validated by Bland-Altman analysis, supports the application of BIA for epidemiological studies in European children using the developed equations.
