    Some biological properties in the Akgöl (Fethiye - Muǧla) population of the mosquitofish Gambusia affinis (Baird & Girard, 1853); [Akgöl (Fethiye - Muǧla) sivrisinek baliǧi Gambusia affinis (Baird & Girard, 1853) populasyonunun bazi biyolojik özellikleri]
    (2003) Öztürk Ş.; Ikiz R.
    In this study, 705 mosquitofish Gambusia affinis (Baird & Girard, 1853) were caught in Akgöl Lake near the town of Fethiye in Muǧla province between November 1998 and October 1999, and the biological characteristics of their growth, reproduction and feeding were studied in detail. In the mosquitofish population, the 0 aged group comprised 97.58% and the 1+ aged group 2.42%; the proportion of females was 81.40%, and that of males was 18.60%. Total length (TL) varied from 1.3 to 5.5 cm; total weight was between 0.02 and 2.31 g. The average numbers of developing eggs were 21.90 (0+) and 52.81 (1); and the average egg productivity per gram was between 27.71 (0+) and 31.71 (1). The average condition number was 1.16 ± 0.16. The maximum condition number was 1.38, in November 1998. In the population, 34.68% of nutrition consisted of Diptera species (22.44% of this was mosquito larvae), 13.26% Nereidae family members and 11.22% Amphipoda members. Consequently, the fact that mosquito larvae are of great importance in the nourishment regime of G. affinis indicates the significance of G. affinis in the struggle against mosquitoes.

    Some biological properties of mosquitofish populations (Gambusia affinis) living in inland waters of the Western Mediterranean Region of Turkey
    (2004) Öztürk Ş.; Ikiz R.
    Gambusia affinis, Baird & Girard, 1853, originally comes from North America and has been distributed all over the world for the biological control of mosquitoes. This study aimed to determine some biological properties, such as structure, age, growth and reproduction of the populations of G. affinis in Turkey. For this purpose, between November 1998 and October 1999, 2026 mosquitofish were caught in the wetlands of Fethiye-Akgöl, Dalaman and Ortaca in Muǧla province in the western Mediterranean region of Turkey and the data found were compared. In the Fethiye-Akgöl population the percentage of the 0+ age group was 97.59%, and of the 1+ age group was 2.41%; in the Dalaman population percentage of the 0+ age group was 99.71%, and of the 1+ age group was 0.29%; in the Ortaca population percentage of the 0+ age group was 94.37%, and of the 1+ age group was 5.63%. The mosquitofish population in Fethiye was 81.42% female and 18.58% male, in Dalaman 71.55% female and 28.45% male, and in Ortaca 70.42% female and 29.58% male. Total length (TL) in the Fethiye-Akgöl population was 1.3-5.5 cm. in Dalaman 1.7-5.5 cm and in Ortaca 1.3-5.8 cm; and total weight (W) in Fethiye-Akgöl was 0.02-2.31 g, in Dalaman 0.06-2.58 g and in Ortaca 0.02-5.83 g. In each population the gonadosomatic index (GSI) increased in March and April, had a slight decrease in May and increased again in mid May. At the beginning of January the GSI of the Fethiye population started to decrease again and the GSI decreased in Dalaman and Ortaca populations beginning in mid July. This shows that the mosquitofish is a bivoltine species. The average number of eggs belonging to each age group was 21.90 (0+) and 52.81 (1+) in Fethiye, 27.11 (0+) and 91.0 (1+) in Dalaman, and 28.24 (0+) and 81.78 (1+) in Ortaca. Average fecundity per gram was between 27.71 (0+) and 31.71 (1+) in Fethiye-Akgöl, between 42.97 (0+) and 39.99 (1+) in Dalaman, and between 35.28 (0+) and 37.39 (1+) in Ortaca.

    Objective: Nutritional status assessment, dysphagia evaluation and enteral feeding decision are important determinants of prognosis in acute neurovascular diseases. Materials and Methods: NöroTek is a point prevalence study conducted with the participation of 87 hospitals spread across all health sub regions of Turkey conducted on 10-May-2018 (World Stroke Awareness Day). A total of 972 hospitalized neurovascular patients [female: 53%, age: 69±14; acute ischemic stroke in 845; intracerebral hematoma (ICH) in 119 and post-resuscitation encephalopathy (PRE) in 8] with complete data were included in this sub-study. Results: Gastrostomy was inserted in 10.7% of the patients with ischemic stroke, 10.1% of the patients with ICH and in 50% of the patients with PRE. Independent predictors of percutaneous endoscopic gastrostomy (PEG) administration were The National Institutes of Health Stroke Scale score at admission [exp (β): 1.09 95% confidence interval (CI): 1.05-1.14, per point] in ischemic stroke; and mechanical ventilation in ischemic [exp (β): 6.18 (95% CI: 3.16-12.09)] and hemorrhagic strokes [exp (β): 26.48 (95% CI: 1.36-515.8)]. PEG was found to be a significant negative indicator of favorable (modified Rankin’s scale score 0-2) functional outcome [exp (β): 0.032 (95% CI: 0.004-0.251)] but not of in-hospital mortality [exp (β): 1.731 (95% CI: 0.785-3.829)]. Nutritional and swallowing assessments were performed in approximately two-thirds of patients. Of the nutritional assessments 69% and 76% of dysphagia assessments were completed within the first 2 days. Tube feeding was performed in 39% of the patients. In 83.5% of them, tube was inserted in the first 2 days; 28% of the patients with feeding tube had PEG later. Conclusion: The NöroTek study provided the first reliable and large-scale data on key quality metrics of nutrition practice in acute stroke in Turkey. In terms of being economical and accurate it makes sense to use the point prevalence method. © 2022 by Turkish Neurological Society.

    Objective: To reveal the profile and practice in patients with acute stroke who received intravenous tissue plasminogen activator (IV tPA) and/or neuro-interventional therapy in Türkiye. Materials and Methods: On World Stroke Awareness Day, May 10, 2018, 1,790 patients hospitalized in 87 neurology units spread over 30 health regions were evaluated retrospectively and prospectively. Results: Intravenous tPA was administered to 12% of 859 cases of acute ischemic stroke in 45 units participating in the study. In the same period, 8.3% of the cases received neurointerventional treatment. The rate of good prognosis [modified Rankin score (mRS) 0–2] at discharge was 46% in 83 patients who received only IV tPA [age: 67 ± 12 years; National Institutes of Health Stroke Scale (NIHSS): 12 ± 6; hospital stay, 24 ± 29 days]; 35% in 51 patients who underwent thrombectomy (MT) alone (age: 64 ± 13 years; NIHSS: 14.1 ± 6.5; length of hospital stay, 33 ± 31 days), 19% in those who received combined treatment (age: 66 ± 14 years; NIHSS: 15.6 ± 5.4; length of hospital stay, 26 ± 35 days), and 56% of 695 patients who did not receive treatment for revascularization (age: 70 ± 13 years; NIHSS: 7.6 ± 7.2; length of hospital stay, 21 ± 28 days). The symptom-to-door time was 87 ± 53 minutes in the IV treatment group and 200 ± 26 minutes in the neurointerventional group. The average door-to-needle time was 66 ± 49 minutes in the IV tPA group. In the neurothrombectomy group, the door-to-groin time was 103 ± 90 minutes, and the TICI 2b-3 rate was 70.3%. In 103 patients who received IV tPA, the discharge mRS 0–2 was 41%, while the rate of mRS 0–1 was 28%. In 71 patients who underwent neurothrombectomy, the mRS 0–2 was 31% and mRS 0–1 was 18%. The door-to-groin time was approximately 30 minutes longer if IV tPA was received (125 ± 107 and 95 ± 83 minutes, respectively). Symptomatic bleeding rates were 4.8% in IV recipients, 17.6% among those who received only MT, and 15% in combined therapy. Globally, the hemorrhage rate was 6.8% in patients receiving IV tPA and 16.9% in MT. Conclusion: IV thrombolytic and neurointerventional treatment applications in acute ischemic stroke in Türkiye can provide the anticipated results. Heterogeneity has begun to be reduced in our country with the dissemination of the system indicated by the “Directive on Health Services to be Provided to Patients with Acute Stroke.”. © Copyright 2023 by the Turkish Neurological Society / Turkish Journal of Neurology published by Galenos Publishing House.

    Objective: Atrial fibrillation (AF) is the most common directly preventable cause of ischemic stroke. There is no dependable neurology-based data on the spectrum of stroke caused by AF in Türkiye. Within the scope of NöroTek-Türkiye (TR), hospital-based data on acute stroke patients with AF were collected to contribute to the creation of acute-stroke algorithms. Materials and Methods: On May 10, 2018 (World Stroke Awareness Day), 1,790 patients hospitalized at 87 neurology units in 30 health regions were prospectively evaluated. A total of 929 patients [859 acute ischemic stroke, 70 transient ischemic attack (TIA)] from this study were included in this analysis. Results: The rate of AF in patients hospitalized for ischemic stroke/TIA was 29.8%, of which 65% were known before stroke, 5% were paroxysmal, and 30% were diagnosed after hospital admission. The proportion of patients with AF who received “effective” treatment [international normalization ratio ≥2.0 warfarin or non-vitamin K antagonist oral anticoagulants (NOACs) at a guideline dose] was 25.3%, and, either no medication or only antiplatelet was used in 42.5% of the cases. The low dose rate was 50% in 42 patients who had a stroke while taking NOACs. Anticoagulant was prescribed to the patient at discharge at a rate of 94.6%; low molecular weight or unfractionated heparin was prescribed in 28.1%, warfarin in 32.5%, and NOACs in 31%. The dose was in the low category in 22% of the cases discharged with NOACs, and half of the cases, who received NOACs at admission, were discharged with the same drug. Conclusion: NöroTekTR revealed the high but expected frequency of AF in acute stroke in Türkiye, as well as the aspects that could be improved in the management of secondary prophylaxis. AF is found in approximately one-third of hospitalized acute stroke cases in Türkiye. Effective anticoagulant therapy was not used in three-quarters of acute stroke cases with known AF. In AF, heparin, warfarin, and NOACs are planned at a similar frequency (one-third) within the scope of stroke secondary prophylaxis, and the prescribed NOAC dose is subtherapeutic in a quarter of the cases. Non-medical and medical education appears necessary to prevent stroke caused by AF. © 2023 by the Turkish Neurological Society / Turkish Journal of Neurology published by Galenos Publishing House.
