Odnos krimsko-kongoanske hemoragijske groznice i klime: utječe li klima na broj ovih bolesnika?

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral zoonosis. The incidence of zoonotic diseases has been shown to be affected by climatic factors. In this study, we evaluated patients endemic to the CCHF region and examined the relationship between the number of patients and climatic properties of the region where they lived. The study included 548 CCHF patients. Along with the patient demographic and clinical characteristics, we recorded temperature, humidity and precipitation in the places where they lived at the time of their admission to the hospital. In addition to temperature, humidity and precipitation at the time of patient admission, these values were assessed at one month and three months prior to admission. The relationship between the number of patients and the above-mentioned values was examined. Humidity at the time of and one month prior to hospital admission, and precipitation three months prior to hospital admission were found to affect the number of patients admitted to the hospital for CCHF. In conclusion, climate appeared to affect the number of CCHF patients. We believe that the number of patients presenting to the hospital with CCHF could be predicted by taking into account climatic properties of the places where CCHF has been recorded, along with under-taking necessary measures.Krimsko-kongoanska hemoragijska groznica (KKHG) je virusna zoonoza koju prenose krpelji. Dokazano je da klimatski čimbenici utječu na incidenciju zoonotskih bolesti. U ovom smo istraživanju ispitivali bolesnike endemske za područje KKHG te odnos broja bolesnika i klimatskih svojstava područja u kojem oni žive. U istraživanje je bilo uključeno 548 bolesnika s KKHG. Uz demografske i kliničke značajke bolesnika bilježili smo temperaturu, vlagu i količinu padalina u mjestu gdje su bolesnici živjeli u vrijeme prijma u bolnicu. Uz vrijednosti temperature, vlage i količine padalina u vrijeme prijma bolesnika u bolnicu, vrijednosti ovih parametara procijenjene su za jedan mjesec i tri mjeseca prije prijma u bolnicu. Tada smo ispitali odnos broja bolesnika i gore spomenutih vrijednosti. Pokazalo se da razina vlage u vrijeme prijma i jedan mjesec prije prijma u bolnicu, kao i količina padalina tri mjeseca prije prijma u bolnicu utječu na broj bolesnika primljenih u bolnicu zbog KKHG. U zaključku, čini se da klima utječe na broj bolesnika s KKHG. Vjerujemo da bi se broj bolesnika koji dolaze u bolnicu zbog KKHG mogao predvidjeti uzimajući u obzir klimatska svojstva u mjestima gdje je zabilježena KKHG, a time bi se isto tako mogle poduzeti odgovarajuće mjere

Severity and Management of patients with Snake and Scorpion Envenomation Admitted to an Intensive Care Unit in Southeastern Turkey: A retrospective study

Background: Snake and scorpion envenomation is a common public health problem in many regions of the world. Life-threatening emergencies may occur in patients with snake and scorpion envenomation; therefore, these patients may be required intensive care unit (ICU) follow-up. Our objective was to present the demographic and clinical characteristics, treatment modalities and short term outcomes of patients with snake and scorpion envenomation who followed up in our tertiary hospital ICU. Methods: Patient records were retrospectively searched and snake or scorpion envenomation patients with ICU stay were identified with relevant keywords and ICD-10 codes between January 2010 and September 2019. All cases with ICU stay were included for study analysis, regardless of patient age. Scorpion and snake envenomation managed in outpatient clinic were excluded from our data. Poisoning severity score (PSS) system was used to present signs and symptoms and PSS was calculated. Primary and critical care treatment modalities were identified and analyzed. Results: Forty patients (25 with snake bites [62.5%] and 15 with scorpion sting [37.5%]) were included in this retrospective study. Local and systemic effects have been reported in 33 (82.5%) and in 27 patients (67.5%), respectively. Majority of patients suffered from pain or disturbances in sensory neural, hematological, cardiovascular or metabolic systems. Median PSS was 2 (0-4) and median length of stay in ICU was 2 days (1-12). Mortality rate was 2.5%. Antivenom immunoglobulins (n=32, %80.0), systemic antibacterial agents (n=24, 60%), and paracetamol (n=21, 52.5%) were the most common systemically administered treatments. Surgical interventions were performed in 4 patients (10%) Conclusions: We reported that snake and scorpion envenomation were mostly admitted to the ICU with local and/or systemic symptoms for advanced monitoring and observation. Although life treating emergencies and mortality was uncommon in our study, we think that these patients should be closely followed up in ICU

Length-weight relationships of 28 fish species caught from demersal trawl survey in the Middle Black Sea, Turkey

This study provides updated the length-weight relationships and Fulton's condition factor of 28 fish species belonging to 23 families from the Black Sea. Samples were collected along the depths between 0-100 meters by demersal trawl surveys conducted seasonally from May 2017 to September 2019. A total of 83,885 specimens were collected. The length-weight relationships and Fulton's condition factor, minimum, maximum and mean lengths, total weights, descriptive statistics, and growth type were provided for all the species. The results indicate that LWR parameters of b varied from 2.2039 to 3.737 and Fulton's condition factor varied between 0.004 and 1.18. These findings could be useful for monitoring and management of sustainable fisheries and habitat health

Brucellosis in Patients with Crimean-Congo Hemorrhagic Fever

Background: Crimean-Congo hemorrhagic fever (CCHF) is a fatal zoonotic viral disease caused by infection with a tick-borne virus of the genus Nairovirus. In this study, we investigated the incidence of brucellosis in patients diag­nosed with CCHF. Methods: Overall, 169 patients hospitalized with an initial diagnosis of CCHF were included in 2011 in To­kat/ Turkey. Immunoglobulin M (IgM) antibodies and/or PCR results were used in the laboratory diagnosis of CCHF, while plate and standard tube agglutination (STA) tests were used to diagnose brucellosis. Results: Overall, 120 patients (79%) with positive PCR tests were diagnosed with CCHF. Five (4.16%) were also diag­nosed with brucellosis based on the positive plate and STA test results. Four patients (2.36%) had negative CCHF PCR and positive STA test results. Conclusion: Brucellosis and CCHF can mimic each other and that all patients with CCHF or brucellosis should be screened for both conditions

Effect of microcapsulated red phosphorus on flame retardant, thermal and mechanical properties of thermoplastic polyurethane composites filled with huntite&hydromagnesite mineral

The effect of microcapsulated red phosphorus (mRP) was studied on the flame retardant, thermal and mechanical properties of thermoplastic polyurethane (TPU) composites containing Huntite&hydromagnesite (HH). The flame retardant properties of TPU based composites were investigated using limiting oxygen index (LOI), vertical burning test (UL 94), thermogravimetric analysis (TGA) and mass loss calorimeter. The mechanical properties of composites were studied using tensile test and dynamic mechanical analysis (DMA). According to the test results, the adjuvant effect of mRP was observed in terms of both flammability and mechanical properties of composites. The highest LOI value (32.5), the highest UL-94 rating (VO) and the lowest pHRR (155 kW/m(2)) value were observed with the partial substitution of 7 wt% mRP with HH. The tensile strength also increased at about 60% with respect to TPU/50HH. The mRP showed the synergistic effect by increasing the barrier effect of residue in the condensed phase and the formation of active radicals in the gas phase. The mRP showed adjuvant effect on mechanical properties due to the plasticizing and compatibilizer effect of low molecular weight epoxy resin carrier. (C) 2016 Elsevier Ltd. All rights reserved
