Leishmaniosis (or leishmaniasis) is a neglected parasitosis most commonly transmitted by the sandfly bite. Changes in temperature, precipitation, and humidity can greatly affect the vectors and reservoir hosts. This study aimed to determine the association between temperature, air humidity, and weather conditions with the incidence of leishmaniasis in Montenegro during a seven-decade period (1945–2014) and to statistically compare and correlate the obtained data. In the studied period, there were 165 registered cases of leishmaniosis, 96.4%, in the coastal and central region of Montenegro, with an average incidence rate of 0.45/100.000. The visceral form of leishmaniosis predominated (99% of the cases), with only one case of cutaneous disease. Climate factors (average temperature, air humidity, and precipitation) had an impact on the occurrence of leishmaniosis in Montenegro. Air temperature elevated by 1 °C in all regions of Montenegro was significantly correlated with an increased incidence of leishmaniosis, by 0.150 (0.013 to 0.287; p < 0.05). In order to improve prevention and control of this disease, it is also necessary to investigate other factors with a possible impact on the number of cases of this neglected parasitosis.

Background and Objectives: Individuals with heroin-related opioid use disorder are at high risk of poor oral health and impaired oral health-related quality of life (OHRQoL). However, data on the determinants of OHRQoL in this population remain limited. This study aimed to assess oral health status and OHRQoL and to identify key predictors of OHRQoL among hospitalized patients with heroin-related opioid use disorder. Materials and Methods: A cross-sectional study was conducted among 97 hospitalized patients with heroin-related opioid use disorder. Data were collected through structured interviews and clinical oral examinations, including the Decayed, Missing, and Filled Teeth (DMFT) index and the Simplified Oral Hygiene Index (OHI-S). OHRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14). Spearman correlation and multiple linear regression analyses were performed to examine associations and identify predictors of OHRQoL. Results: Participants had poor oral health, with high DMFT (19.1 ± 6.1) and OHI-S (2.0 ± 1.2) scores. OHRQoL was markedly impaired, with a mean OHIP-14 score of 29.6 ± 7.0, particularly in the psychological and social domains. OHIP-14 scores were strongly correlated with DMFT (r = 0.754, p < 0.001) and OHI-S (r = 0.552, p < 0.001). Longer duration of heroin use was associated with higher DMFT scores, poorer oral hygiene, and greater OHRQoL impairment. Multiple linear regression analysis identified unstable housing/homelessness (β = 0.166, p = 0.012), DMFT (β = 0.624, p < 0.001), and OHI-S (β = 0.272, p = 0.007) as significant predictors of poorer OHRQoL. Conclusions: Individuals with heroin-related opioid use disorder experienced substantial oral health burden and impaired OHRQoL, strongly associated with caries experience, poor oral hygiene, and housing instability. These findings highlight the need to integrate prevention-oriented dental care into addiction treatment services and to address the broader social determinants of oral health.

The aim of this study is to show how public health surveillance of travel-associated Legionnaires' disease was conducted in Europe, as well as in Montenegro. The estimations of the European Centre for Disease Prevention and Control (ECDC) indicate that every year about one thousand tourists from Europe get infected by legionellae during their holiday and stay at hotels across the continent. The European Legionnaires' Disease Surveillance Network (ELDSNet) was established with the aim to detect, control and prevent cases, clusters and sources of outbreaks of travel-associated Legionnaires' disease within the European Union (EU) and European Economic Area (EEA), and to assist with detection and response to outbreaks outside the EU/EEA. Sharing information leads to concrete and timely actions of member states of ELDSNet, so that residents of the EU/EEA who travel abroad are protected. ECDC recommends a set of measures that should be followed by public health authorities and tourist sector of the country which was visited by the traveler who caught this disease. If the measures are not carried out, information is published online and European tour operators can use the information when booking holiday packages abroad. Operating procedures provide a set of common measures which should be followed by all EU/ EEA member states involved in the protection of their residents against Legionnaires' disease. Each case of Legionnaires' disease which is reported in tourists, who stayed in Montenegro, is epidemiologically analyzed according to the operating procedures of ELDS Network.
