IVIg-induced headache: prospective study of a large cohort with neurological disorders.

BACKGROUND: Intravenous immune globulin (IVIg) is frequently used in some neurological diseases and is also the first-line therapy in Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy, and multifocal motor neuropathy. We aimed to evaluate the frequency and characteristics of headaches, which is one of the most common side effects of IVIg treatment. METHODS: Patients who received IVIg treatment for neurological diseases were prospectively enrolled in 23 centers. Firstly, the characteristics of patients with and without IVIg-induced headaches were analyzed statistically. Then, patients with IVIg-induced headaches were classified into three subgroups determined by their history: no primary headache, tension-type headache (TTH), and migraine. RESULTS: A total of 464 patients (214 women) and 1548 IVIg infusions were enrolled between January and August 2022. The frequency of IVIg-related headaches was 27.37% (127/464). A binary logistic regression analysis performed with significant clinical features disclosed that female sex and fatigue as a side effect were statistically more common in the IVIg-induced headache group. IVIg-related headache duration was long and affected daily living activities more in patients with migraine compared to no primary headache and TTH groups (p = 0.01, respectively). CONCLUSION: Headache is more likely to occur in female patients receiving IVIg and those who develop fatigue as a side effect during the infusion. Clinicians' awareness of IVIg-related headache characteristics, especially in patients with migraine, may increase treatment compliance.

Development and evaluation of the efficacy of a web-based education program among cancer patients undergoing treatment with systemic chemotherapy: a randomized controlled trial.

PURPOSE: The study aimed to develop a web-based education program among cancer patients undergoing treatment with systemic chemotherapy and to evaluate the efficacy of the program on symptom control, quality of life, self-efficacy, and depression. METHODS: A web-based education program was prepared in line with patient needs, evidence-based guidelines, and expert opinions and tested with 10 cancer patients. The single-blind, randomized controlled study was conducted at a medical oncology unit of a university hospital. Pretests were applied to 60 cancer patients undergoing treatment with systemic chemotherapy, and the patients (intervention: 30, control: 30) were randomized. The intervention group used a web-based education program for 3 months, and they were allowed to communicate with researchers 24/7 via the website. The efficacy of a web-based education program at baseline and after 12 weeks was evaluated. The CONSORT 2010 guideline was performed. RESULTS: In the first phase results of the study, it was found that most of the patients with cancer wanted to receive education about symptom management and the side effects of the treatment. Expert opinions on the developed website were found to be compatible with each other (Kendall's Wa = 0.233, p = 0.008). According to the randomized controlled study results, patients who received web-based education reported significantly fewer symptoms (p = 0.026) and better quality of life (p = 0.001), but there was no statistically significant difference in the self-efficacy and depression levels during the 3-month follow-up period (p˃0.05). The most frequently visited links in the web-based education program by the patients with cancer were the management of chemotherapy-related symptoms (62.6%). CONCLUSION: A web-based education program was found to be efficacy in remote symptom management and improving the quality of life of cancer patients. TRIAL REGISTRATION: www.

Impact of autologous stem cell transplantation on survival outcomes in patients with peripheral T cell lymphoma.

Data about the timing of autologous stem cell transplantation (ASCT) in peripheral T cell lymphoma (PTCL) are conflicting. We aimed to investigate the impact of the sequence of ASCT on the survival outcomes in patients with PTCL. Analyzes were performed retrospectively in a total of 81 patients, 16 of whom underwent upfront ASCT and 12 received salvage ASCT. In univariate analysis, upfront ASCT reduced the risk of progression and death by 77% (Hazard ratio (HR): 0.23, 95% confidence interval (CI): 0.09-0.60) (p = 0.003) and by 84% (HR: 0.16, 95% CI: 0.5-0.55) (p = 0.003), respectively. However, in multivariate analysis, only salvage ASCT predicted a more favorable progression-free and overall survival (HR: 0.17, 95% CI: 0.06-0.48, p = 0.001 and HR: 0.20, %95 GA: 0.06-0.62, p = 0.005, respectively). In conclusion, regardless of first-line therapy, patients have more favorable outcomes if they receive salvage ASCT. Upfront ASCT does not add clinically significant benefit to survival outcomes.

How to manage MuSK antibody-positive myasthenic crisis during pregnancy?

Myasthenia gravis (MG) is an autoimmune disease that is characterised by the formation of antibodies against acetylcholine receptors in the postsynaptic membrane of the neuromuscular junction. The course of the disease cannot be predicted during pregnancy. A subtype of MG with positive muscle-specific receptor tyrosine kinase (anti-MuSK) antibodies exhibits more localised clinical characteristics and a poor response to treatment compared with the disease subtype that involves positivity for acetylcholine receptor antibodies. Myasthenic crisis is more frequently observed in anti-MuSK-positive myasthenia patients. Anti-MuSK-positive myasthenic crisis management is very difficult and a risky situation during pregnancy. The reported case was 30 years old, female, 9 weeks pregnant and musk antibody positive. She stopped her treatment without asking her doctor because she was planning pregnancy in the 6-month period before her hospitalization. She was intubated for a long time in the intensive care unit due to myasthenic crisis and was very resistant to treatment. During this period, her pregnancy was terminated due to fetal anomaly. Plasmapheresis, IVIg and immunosuppressive treatments were applied. Our patient was discharged after a period of about 10 weeks. We share our treatment management.

Barriers to Adoption of Electronic Health Record Systems from the Perspective of Nurses: A Cross-sectional Study.

This study report aimed to investigate the barriers to implementation of electronic health record systems from the perspective of nurses. The research data comprised responses from nurses working in a university hospital. Our data collection instruments were the Participant Information Form and EHR Nurse Opinion Questionnaire, which were developed by the researchers. Data analysis was presented as summary statistics, including mean values of variables, standard deviation, frequency, and percentages. A total of 160 nurses participated in the study. The mean age of participants was 30.94 ± 0.59 years, and 77.5% were university graduates. Barriers to adoption of the electronic health record system included high number of patients (82.8%), limited time (79%), lack of knowledge and skills for effective use of the system (22.9%), lack of user-friendly interface and inability to create a common language within the team (17.8%), and attachment to the traditional method (17.2%). Although most nurses thought that the electronic health record system offered some advantages, they reported that factors such as large numbers of patients, limited time, and lack of user-friendly interface hindered its adoption. Innovative strategies should be explored to develop user-friendly designs for electronic health records and to produce solutions for nursing shortages to increase the time allocated for patient care.

Student Nurse Knowledge of and Attitudes Toward Pressure Injury Prevention: How Sufficient Is Undergraduate Education?

OBJECTIVES: To assess the knowledge and attitudes of student nurses regarding evidence-based guidelines for preventing pressure injuries. METHODS: This study used a descriptive research design. The participants included second-, third-, and fourth-year nursing students completing their bachelor's degrees at a faculty of nursing in Turkey. Data collection forms consisted of a student nurse information form, the Pressure Ulcer Prevention Knowledge Assessment Instrument, and the Attitude Towards Pressure Ulcer Prevention Instrument. RESULTS: The overall mean score for knowledge was 49.9% (11.7/26). The highest scores for the instrument's subthemes were for nutrition (72%), and the lowest were for etiology and development (40.1%). The overall mean attitude score was 42.20 ± 2.40, although a statistically significant difference among grades was found (P < .001). The highest mean scores showed agreement among students that pressure injury prevention should be a priority (10.50 ± 1.43). A significant difference was found in the competence subscale according to the number of dressing changes observed and sense of competence in pressure injury care (P = .003). A weak but statistically significant positive relationship was found between knowledge and attitude scores (r = 0.158; 95% confidence interval, .040-.269; P < .001). CONCLUSIONS: This study revealed that certain revisions are needed in the nursing curriculum to improve the knowledge and attitudes of nursing students toward the prevention and care of pressure injuries. More details should be covered in the classroom and laboratories through simulation or clinical practice for improved management of pressure injuries.

Fertility in testicular cancer patients: a single-centre study in Turkey.

BACKGROUND: Testicular cancer is a rare type of cancer in males. Since the disease is seen in young men and long-term survival is ensured following a high treatment success rate, fertility in testicular cancer patients is much more important. Prior to commencement of cancer treatment, patients are given counselling with regard to infertility and sexual function, and sperm banking is commonly carried out. The aim of this study was to assess the fertility status prior to and following treatment of monitored testicular cancer patients whose treatment had been completed. METHODS: 110 patients diagnosed with and treated for testicular cancer at the Medical Oncology Clinic at Akdeniz University during the years 2000-2016 were evaluated for the study. The patients' disease and treatment information was obtained from their records. The patients' characteristics and fertility statuses were determined by means of interviews with the patients. RESULTS: The median age of the patients was 36 (20-73) and 39.1% of them (n = 43) were aged between 30 and 39. The average length of follow-up was 6.20 ± 3.36 (2-17) years. It was determined that 42.7% of the patients had banked sperm following diagnosis and that 74.5% of them had received counselling. Following treatment, 33 patients (30%) fathered children. The average time taken to father children after treatment was 3 years. CONCLUSION: In testicular cancer patients, fatherhood is achieved spontaneously or with the cryopreservation process. Counselling plays an important role at the time of diagnosis. It is essential that health professionals in oncology clinics give counselling about fertility in testicular cancer.

Psychometric validation of the Turkish version of the Supportive Care Needs Survey for Partners and Caregivers (SCNS-P&C-T) of cancer patients.

OBJECTIVE: To evaluate the validity and reliability study of the Supportive Care Needs Survey for partners and caregivers of cancer patients in Turkish society (SCNS-P&C-T). METHODS: This cross-sectional survey followed by a test-retest reliability and psychometric validation study was conducted with 270 participants. The research data were collected using a patient and caregiver demographic survey, the SCNS-P&C-T, the Caregiver Strain Index, and the Hospital Anxiety and Depression Scale. RESULTS: Ten expert opinions were found to be consistent for content validity of the scale (I-CVI = 0.993, S-CVI = 0.956). The confirmatory factor analysis could not confirm the factor structure of the original scale. Therefore, an exploratory factor analysis was performed and the scale factor structure was determined. These factor structures are (a) psychological and emotional needs, (b) health care and information, (c) work and social needs, (d) communication and family needs. CONCLUSION: The SCNS-P&C-T is a valid and reliable tool which can be used to identify unmet needs among caregivers in Turkish populations.

Lactate Level Is More Significant Than Carboxihemoglobin Level in Determining Prognosis of Carbon Monoxide Intoxication of Childhood.

OBJECTIVES: To evaluate the demographics, risk factors, correlation between carbon monoxide (CO) level and clinical findings, and laboratory findings determining the prognosis and ischemic myocardial injury due to CO intoxication in patients admitted to pediatric emergency department. MATERIALS AND METHODS: Six hundred seventy-four patients were admitted with CO intoxication between May 2007 and October 2009, 288 patients who required hospitalization were enrolled into the study prospectively. RESULTS: Incidentally, 144 (50%) of the patients were evenly distributed as girls and boys. Their age ranged between 7 months and 17 years; mean age was 8.6 years. The mean CO level was 26.8. The high levels were detected regarding lactate in 199 (90.1%) patients, creatine kinase (CK)-MB in 130 (45.1%) patients, CK in 80 (27.8%) patients, cardiac Troponin I in 35 (17.2%) patients, and lactate dehydrogenase in 34 (15.7%) patients. There was a significant positive correlation when symptoms like syncope, loss of consciousness, and convulsion were compared with carboxyhemoglobin, lactate, CK, CK-MB, and lactate dehydrogenase levels (P < 0.05), whereas there was no correlation when compared with cardiac Troponin I (P > 0.05). To determine the accuracy of predicting severe CO intoxication, sensitivity of 52.6% and specificity of 85.7% were found in receiver operating characteristic analysis when the lactate level was 3.85 mmol/L, whereas sensitivity of 70.5% and specificity of 59.6% were found when the carboxyhemoglobin level was 27.1%. One hundred forty-six (%50.8) of the patients had normal electrocardiographic findings, whereas 135 (46.8%) had sinus tachycardia, 6 (2%) had right branch block, and 1 (0.34%) had atrioventricular block. In 34 patients who had high CK-MB and Troponin I levels, only sinus tachycardia was detected in electrocardiography, and there were no ST changes. Hyperbaric oxygen was necessary in 2 patients admitted with coma. CONCLUSIONS: In children admitted because of CO intoxication, the blood lactate levels may give more accurate information in terms of loss of consciousness and convulsion, lactate level could be taken as a measure of severe poisoning and may help to decide for hyperbaric oxygen treatment.

Rocuronium: automatic infusion versus manual administration with TOF monitorisation.

TOF (train-of-four) monitoring provides objective data in application of neuromuscular blocking agent. Thus, applicator-based differences are eliminated and optimum muscle relaxation is maintained during operation. In the present study, we aimed to compare the effects of target-controlled infusion system and standard TOF monitoring, on use of rocuronium. ASA I-II patients, who were aged between 18 and 75 years and scheduled for elective abdominal surgery at Haydarpasa Numune Training and Research Hospital, were enrolled in the study. In order to evaluate neuromuscular blockade, the patients in Group 1 were connected to the acceleromyography device of the target-controlled infusion pump (Veryark-CLMRIS-I-China) while the ones in Group 2 were connected to the routinely used acceleromyography device (TOF Watch SX). There was no significant difference between groups regarding patient characteristics, the durations of anaesthesia and surgery, quality of intubation, time to extubation and time to recovery (TOF ratio of 0.9). Intubation time was significantly longer in Group 1 (Automated group) as compared to Group 2 (Control group) (p < 0.05). The total rocuronium amount used in Group 1 was found to be significantly higher than the amount used in Group 2 (p < 0.05). There was no clinical evidence of residual neuromuscular blockage or reoccurrence of neuromuscular blockage in any patient in either group. Both methods can be used for administration of neuromuscular blocker agent during moderate time anesthesia. No advantage was noted when rocuronium was administered via automatical infusion pump during anaesthesia.

Cultural sensitivity levels of university students receiving education in health disciplines.

Medical and nursing students are expected to be more competent in terms of being acquainted with different cultures and approaching culturally, compared to many other disciplines. This descriptive study was designed to evaluate the cultural sensitivity levels of nursing and medical students and the affecting factors. One hundred and eleven nursing and 164 medical students were included in the study. The data were collected by using a questionnaire questioning the variables that were thought to affect the cultural sensitivity of students and the intercultural sensitivity scale. According to results of the study; it was observed that university students receiving education in the fields of medicine and nursing had good cultural sensitivity levels and those interacting with people from other cultures and speaking a foreign language had significantly higher cultural sensitivity levels (p < 0.05). According to these results, it was thought that it would be useful to develop plannings aimed at increasing the language proficiency in university curriculums and abroad experience opportunities of students, and to design qualitative studies based on interviews and observations aimed at examining the factors affecting the intercultural sensitivity.

The Diagnostic Value of Abnormal Bone Marrow Signal Changes on Magnetic Resonance Imaging: Is Bone Marrow Biopsy Essential?

BACKGROUND: It is essential to determine whether bone marrow signal changes on magnetic resonance imaging (MRI) represent a physiological response or pathology; at present, the clinical significance of these signal changes is unclear. It is unknown whether a bone marrow biopsy is required when bone marrow signal changes are detected incidentally in individuals without suspected malignancy. OBJECTIVE: The primary purpose of this study was to determine whether incidentally detected bone marrow signal changes on MRI performed for various reasons (at the time of admission or during follow-up) are clinically significant. METHODS: We retrospectively evaluated the bone marrow biopsy clinical and laboratory findings of 42 patients with incidental bone marrow signal changes on MRI between September 2016 and January 2020. We also determined whether the patients were diagnosed with malignancy during admission or follow-up. RESULTS: Of the 42 patients, three (7%) were diagnosed with hematological malignancies during admission, while two were diagnosed with multiple myeloma and one with B-cell acute lymphoblastic leukemia. Of the 42 patients, 35 had a mean follow-up of 40.6 ± 5.3 months. One patient was diagnosed with monoclonal gammopathy of undetermined significance four months after their first admission. CONCLUSIONS: In addition to MRI, detailed clinical and laboratory evaluations should be performed to inform the decision for bone marrow biopsy and exclude hematological malignancy. If there is any doubt, a bone marrow biopsy should be performed. Moreover, since bone marrow signal changes may be a preliminary finding, follow-up of these patients is essential.

Body image and social appearance anxiety in patients with cancer undergoing radiotherapy: Across-sectional study.

BACKGROUND: The body image of patients with cancer can be negatively affected due to treatment toxicities. Changes in body image may cause patients to experience social appearance anxiety. This study aimed to evaluate the body image and social appearance anxiety of patients with cancer undergoing radiotherapy. METHODS: The cross-sectional study was conducted with 153 patients with cancer undergoing radiotherapy in a university hospital. The data were collected with a Patient Information Form, the Body Image Scale, and the Social Appearance Anxiety Scale and the Radiation Therapy Oncology Group Skin Toxicity Criteria. RESULTS: Patients' mean body image score was 15.18 ± 8.26 (min = 0, max = 30), mean social appearance anxiety score was 45.29 ± 14.50 (min = 16, max = 80). Patients with low education levels and low-income levels had higher body image and social appearance anxiety scores (p < 0.01). Body image and social appearance anxiety scores were found to be higher in patients with advanced cancer, grade III-IV skin toxicity, pain, fatigue, and constipation (p < 0.05). CONCLUSIONS: Radiotherapy may negatively affect body image and social appearance anxiety. Assessments of body image and social appearance anxiety regularly before, during, and after treatment are essential. Psychosocial support should be provided to patients to reduce body image and social appearance anxiety and increase their well-being. Patients with cancer especially those who have low income and education levels, advanced cancer stage and skin toxicity, and suffer from pain, fatigue, constipation, etc. should be supported by methods such as counseling and social support groups.

Experience with flexible bronchoscopy for noncoronavirus disease of 2019 indications in pediatric patients during the coronavirus disease of 2019 pandemic.

BACKGROUND AND AIM: Flexible bronchoscopy (FB) poses a risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission due to aerosol generation. This study aimed to assess the utilization, indications, outcomes, and safety of FB in pediatric patients for noncoronavirus disease of 2019 (COVID-19) reasons during the pandemic. MATERIALS AND METHODS: We retrospectively analyzed pediatric patients who underwent FB for non-COVID-19 indications at a tertiary children's hospital's pulmonary clinic during the COVID-19 pandemic. Patients showed no COVID-19 symptoms and tested negative for SARS-CoV-2 by real-time polymerase chain reaction (PCR) of nasopharyngeal and throat swabs within 24 h before the procedure. FBs were conducted in the operating room, with healthcare professionals (HCPs) wearing personal protective equipment, including medical N95 masks, gloves, gowns, and eye protection. RESULTS: Between March 2020 and April 2022, 167 pediatric patients underwent FB for non-COVID-19 indications. Common indications included foreign body aspiration (22.7%), stridor (10.1%), and atelectasis (8.9%). No COVID-19 symptoms were observed in patients on the 1st and 10th days post-FB. During the 1-month follow-up, 52 patients underwent SARSCoV-2 PCR testing, and one patient tested positive in the third week after the procedure. None of the HCPs in the FB team experienced COVID-19 symptoms or tested positive for SARS-CoV-2. CONCLUSION: A bronchoscopy protocol with safety precautions minimized the risk of COVID-19 transmission, allowing safe FB performance for non-COVID-19 indications in pediatric patients during the pandemic. The experience gained in FB during COVID-19 is valuable for similar situations in the future.

The effect of food intake during hemodialysis on blood pressure: A nonrandomized experimental trial.

BACKGROUND: Intradialytic hypotension (IDH) is one of the most important intradialytic complications and is thought to be associated with intradialytic food intake. Allowing intradialytic feeding is still unclear. This study aimed to determine the relationship between IDH and intradialytic food intake. METHODS: A nonrandomized experimental study was conducted to determine the effect of intradialytic food intake on blood pressure (BP) in hemodialysis patients. Each patient was assessed twice using an ambulatory BP monitor with and without intradialytic food intake. RESULTS: The study was completed with 54 patients. Intradialytic hypotension developed in 40 patients (74.1%) during the food intake session, while intradialytic hypotension developed in 22 participants (40%) in the no-food session. Repeated BP readings showed that eating 2 h or more after the start of hemodialysis significantly reduced BP. CONCLUSIONS: Intradialytic food intake affects the development of IDH. Patients who ate during hemodialysis had a trend of higher of IDH than those who ate nothing during hemodialysis. Eating during dialysis is not recommended.

A Prospective Study of Nurse-Led Oral Mucositis Management: Impact on Health Outcomes of Patients Receiving Radiotherapy for Head and Neck Cancer and Lung Cancer.

OBJECTIVES: The study aimed to evaluate the impact of nurse-led mucositis management on the health outcomes of patients receiving radiotherapy for head and neck cancer and lung cancer. The study adopted a holistic approach that involved the patient in the care process by screening, providing education and counseling about mucositis management and integrating it into daily life by the radiotherapy nurse. DATA SOURCES: In this prospective, longitudinal cohort study, 27 patients were assessed and monitored through use of the WHO Oral Toxicity Scale and Oral Mucositis Follow-up Form and educated on mucositis during their radiotherapy through use of the Mucositis Prevention and Care Guide. At the end of radiotherapy, an evaluation of the radiotherapy process was performed. In this study, each patient was followed for 6 weeks from the start of radiotherapy. CONCLUSION: The worst clinical data for oral mucositis and its variables emerged at week 6 of treatment. While the Nutrition Risk Screening score increased over time, weight decreased was observed to decrease. The mean stress level was 4.74 ± 0.33 in the first week and 5.77 ± 0.35 in the last week. It was observed that 88.9% of the patients showed good compliance with the treatment. IMPLICATIONS FOR NURSING PRACTICE: Nurse-led mucositis management contributes to better patient outcomes during the radiotherapy process. Such an approach improves oral care management in patients receiving radiotherapy for head and neck and lung cancer, demonstrating its positive impact on additional patient-focused outcomes.

Reversible Intracranial Cytotoxic Edema Associated with COVID-19: A Case Report.

BACKGROUND: It is well-known that COVID-19 causes pneumonia and acute respiratory distress syndrome, as well as pathological neuroradiological imaging findings and various neurological symptoms associated with them. These include a range of neurological diseases, such as acute cerebrovascular diseases, encephalopathy, meningitis, encephalitis, epilepsy, cerebral vein thrombosis, and polyneuropathies. Herein, we report a case of reversible intracranial cytotoxic edema due to COVID-19, who fully recovered clinically and radiologically. CASE REPORT: A 24-year-old male patient presented with a speech disorder and numbness in his hands and tongue, which developed after flu-like symptoms. An appearance compatible with COVID-19 pneumonia was detected in thorax computed tomography. Delta variant (L452R) was positive in the COVID reverse-transcriptase polymerase chain reaction test (RT-PCR). Cranial radiological imaging revealed intracranial cytotoxic edema, which was thought to be related to COVID-19. Apparent diffusion coefficient (ADC) measurement values in the magnetic resonance imaging (MRI) taken on admission were 228 mm2/sec in the splenium and 151 mm2/sec in the genu. During the follow-up visits of the patient, epileptic seizures developed due to intracranial cytotoxic edema. ADC measurement values in the MRI taken on the 5th day of the patient's symptoms were 232 mm2/sec in the splenium and 153 mm2/sec in the genu. ADC measurement values in the MRI taken on the 15th day were 832 mm2/sec in the splenium and 887 mm2/sec in the genu. He was discharged from the hospital on the 15th day of his complaint with a clinical and radiological complete recovery. CONCLUSION: Abnormal neuroimaging findings caused by COVID-19 are quite common. Although not specific to COVID-19, cerebral cytotoxic edema is one of these neuroimaging findings. ADC measurement values are significant for planning follow-up and treatment options. Changes in ADC values in repeated measurements can guide clinicians about the development of suspected cytotoxic lesions. Therefore, clinicians should approach cases of COVID-19 with CNS involvement without extensive systemic involvement with caution.

Effect of Adiponectin on Acute Experimental Cerebral Ischemia/Reperfusion Injury.

AIM: To examine the effect of adiponectin administration on acute brain injury in an experimental model of cerebral ischemia/ reperfusion (I/R) in rats. MATERIAL AND METHODS: The study animals were divided into the following four groups: group I, sham (did not undergo surgical intervention and did not receive drugs); group II, the I/R model (received the intervention, but did not receive drugs); group III (I/Radiponectin) (the I/R model was used, and the animals were treated with 5 mg/kg adiponectin peritoneally 30 minutes after the ischemia); and group IV (I/R-tirofiban)( the I/R model was used, and the animals were treated with 0.5 mg/kg tirofiban peritoneally 30 minutes after the ischemia). RESULTS: Tumor necrosis factor-? (TNF-?) and interleukin (IL)-1? levels were statistically higher in the I/R group (group II) than in other groups. In the post-hoc (Tukey) test analysis, groups I, III, and IV had significantly lower TNF-? and IL-1? levels after treatment with both tirofiban and adiponectin than group II. No statistically significant difference was found between groups III and IV in terms of TNF-? levels. However, the decreased IL-1? level was more pronounced in group IV (tirofiban) than in other groups. The mean neurologic deficit scores were statistically significantly different among the groups. In the post-hoc (Tukey) test analysis, neurologic deficit scores were statistically significantly lower in groups III and IV than in group II. CONCLUSION: Adiponectin has anti-inflammatory and cerebral protective effects in experimental cerebral I/R injury.

Retrospective Evaluation of the Results of Low-Dose Intravenous Thrombolytic Therapy in Acute Ischemic Stroke.

Objectives: This study aimed to investigate the clinical data of patients with acute ischemic stroke who received low-dose intravenous (IV) thrombolytic therapy (0.9 mg/kg; maximum 50 mg) for various reasons, compare the obtained results with those of patients who received standard-dose thrombolytic therapy, and discuss them in light of the literature. Methods: Patients who received IV thrombolytic therapy within 4.5 h of symptom onset between January 2015 and June 2018 were retrospectively reviewed. Patients were divided into the low-dose group (0.9 mg/kg; max. 50 mg) and the standard-dose group (0.9 mg/kg; max 90 mg) according to the thrombolytic therapy dose, after which demographic data and clinical results were analyzed. Results: A total of 109 patients receiving thrombolytic therapy (19 patients in the low-dose group and 90 patients in the standard-dose group) were included in the study. There was no significant difference between the two groups in terms of good outcome rates (47.4% vs. 52.2%). There was no statistically significant difference in terms of symptomatic and asymptomatic intracerebral hemorrhage rates. Conclusion: Our study showed similar efficacy and safety for low-dose IV thrombolytic therapy compared with standard-dose IV thrombolytic therapy administered within 4.5 h of symptom onset in patients with acute ischemic stroke.
