Comparison of the Effects of COVID-19 Pandemic on Male and Female Gender in Patients Diagnosed with Idiopathic Parkinson's Disease: A Case of Sakarya Province, Turkey.

Introduction: The study aims to evaluate the motor, non-motor, cognitive and psychiatric conditions of our patients diagnosed with Idiopathic Parkinson's Disease (IPD) before and after the COVID-19 pandemic and to investigate the effect of the pandemic on male and female genders. Methods: Ninety patients were included in the study. Demographic data such as age, gender, and duration of disease, type of disease of the patients were recorded. Patients were then divided into 2 groups: male and female. Movement disorders of both groups before the pandemic, disease stage determined by H&Y and UPDRS at the admission and after the pandemic, Levodopa equivalent dose used were recorded and all patients were surveyed to evaluate their motor, non-motor, cognitive, and psychiatric conditions during the COVID-19 pandemic. The effects of the COVID-19 pandemic on male and female genders were investigated. Results: Of the patients, 40 were male and 50 were female. Daytime drowsiness, weakness, impaired walking, constipation, sleep disorders, and inability to turn in the bed worsened compared to the period before the pandemic. Yet, of the psychiatric symptoms, boredom, unhappiness, anhedonia, irritability, and tension were found to increase during the pandemic. There was a statistically significant difference in UPDRS, H&Y and disease stages before and after the COVID-19 pandemic in both groups, especially in the female group (p<0.05). Conclusion: Although it was more pronounced in female patients with IPD diagnosis, both motor and non-motor symptoms were found to worsen during the COVID-19 pandemic in both groups.

Predictors of Symptomatic Hemorrhage After Endovascular Treatment for Anterior Circulation Occlusions: Turkish Endovascular Stroke Registry.

We evaluated the predictive factors of symptomatic intracranial hemorrhage (SICH) in endovascular treatment of stroke. We included 975 ischemic stroke patients with anterior circulation occlusion. Patients that had hemorrhage and an increase of ≥4 points in their National Institutes of Health Stroke Scale (NIHSS) after the treatment were considered as SICH. The mean age of patients was 65.2±13.1 years and 469 (48.1%) were women. The median NIHSS was 16 (13-18) and Alberta Stroke Program Early CT 9 (8-10). In 420 patients (43.1%), modified Rankin Scale was favorable (0-2) and mortality was observed in 234 (24%) patients at the end of the third month. Patients with high diastolic blood pressure (P<.05) had significantly higher SICH. SICH was significantly higher in those with high NIHSS scores (P<.001), high blood glucose (P<.001), and leukocyte count at admission (P<.05). Diabetes mellitus (DM) (OR 1.90; P<.001), NIHSS (OR 1.07; P<.05), adjuvant intra-arterial thrombolytic therapy (IA-rtPA) (OR, 1.60; P<.05), and puncture-recanalization time (OR 1.01; P<.05) were independent factors of SICH. Higher baseline NIHSS score, longer procedure time, multiple thrombectomy maneuvers, administration of IA-rtPA, and the history of DM are independent predictors of SICH in anterior circulation occlusion.

The Role of De Ritis Ratio as a Clinical Prognostic Parameter in COVID 19 Patients.

BACKGROUND: The study aims to investigate whether the De Ritis ratio can also be used in patients diagnosed with COVID-19 as a follow-up parameter, such as NLR, which is used in the follow-up and treatment of many diseases. METHODS: Ninety-nine patients admitted to our hospital with suspected COVID-19 were included in the study. Demographic data of the patients, their history characteristics, presenting symptoms, filiation status, duration of clinical stay, and length of stay in intensive care unit, intubation, dialysis, and plasmapheresis needs were examined. The patients were divided into two groups: PCR positive and PCR negative. The presenting, 5th day, and the clinical discharge values of AST, ALT, LDH, urea, creatine, eGFR, De Ritis ratio, procalcitonin, CRP, WBC, NLR, ferritin, lymphocyte, and D-dimer levels of the patients in both groups were studied. RESULTS: The DM and CAD presence in the histories of PCR-positive patients was found to be statistically signifi-cantly higher (p = 0.05, p = 0.03, respectively). Presenting symptoms of headache, fatigue, gastrointestinal symptoms, and taste loss were significantly higher in the PCR-positive patients (p = 0.04, p = 0.02, p = 0.03, p = 0.02, respectively). In the PCR-positive patients, a statistically significant correlation was found between the presenting De Ritis ratios and the presenting NLR, 5th day NLR, and NLR at discharge (p = 0.007, p = 0.02, p = 0.015, respectively). In the PCR-positive group, the 1st and 5th day De Ritis ratios of females were statistically significantly higher than males (p = 0.000, p = 0.006, respectively). Albumin, procalcitonin, length of stay in intensive care unit were significantly higher in the PCR-positive patients, while the presenting D-dimer, presenting WBC, and presenting and 5th day lymphocyte values were significantly higher in the PCR-negative patients. CONCLUSIONS: These findings show that the De Ritis ratios can be used in PCR-positive patients as a parameter, such as NLR, to follow-up and determine the prognosis of many diseases.

Pentoxifylline attenuates reperfusion injury in testicular torsion.

OBJECTIVES: An experimental study was designed to evaluate the effects of pentoxifylline (Ptx) on lipid peroxidation, and histopathology in both testes after unilateral testicular torsion and detorsion. MATERIALS AND METHODS: Forty adult male albino Wistar rats were randomly divided into 4 groups of sham operation, sham operation with Ptx, torsion and detorsion, torsion and detorsion with Ptx. After intraperitoneal administration of Ptx at a dose of 50 mg/kg 15 min before torsion; right testes of the rats underwent 30 min of torsion and 30 min of detorsion. Malondialdehyde (MDA) levels were assayed and histopathological changes were evaluated in both testes of all groups. RESULTS: Unilateral testicular torsion and detorsion caused an increase in the MDA levels of both testes. Histopathological evaluation showed interstitial hemorrhage on the ipsilateral side. Pentoxifylline decreased MDA levels on both side, and attenuated interstitial injury on the ipsilateral side. CONCLUSIONS: The results of this study suggest that pentoxifylline treatment attenuates reperfusion damage on both side, possibly with its effects on blood flow and neutrophils. However, further studies are necessary to evaluate the effects of pentoxifylline on testicular torsion.

Changes in blood haemorheological parameters after submaximal exercise in trained and untrained subjects.

The blood stream is affected by viscosity and many other haemorheological factors such as lipid peroxidation in the plasma and red blood cells. The aim of this study was to investigate the changes of haemorheological parameters after submaximal exercise in trained and untrained subjects. The results indicated that heart rate, lymphocyte count, erythrocyte deformability, plasma lipid peroxide levels and erythrocyte glutathione peroxidase activity are increased after submaximal exercise.

Pentoxifylline inhibits overflow and reduces intestinal reperfusion injury.

The aim of this study was to determine the effects of pentoxifylline (Ptx) in reperfusion injury of the small bowel as a leukocyte stabilizer, free radical scavenger, and microcirculatory regulator. Ninety-six male Sprague-Dawley rats were used to determine the biochemical, histopathologic and blood flow changes of the reperfused small intestines after 30 minutes of a warm ischemic insult. Animals were divided into six groups: Sham (S), sham plus Ptx (SP), ischemia (I), ischemia plus Ptx (IP), reperfusion (R), and reperfusion plus Ptx (RP). Pentoxifylline was administered intraperitoneally at a dose of 50 mg/kg 15 minutes before ischemia. The superior mesenteric artery (SMA) was occluded distal to the right colic artery and collateral arcades were ligated as described by Megison. Sixty of the 96 rats (n = 10) were used to determine histopathologic changes, malondialdehyde (MDA), and myeloperoxidase (MPO) levels in tissue. Mucosal lesions were graded on a scale from 0 to 5 as described by Chiu. MDA and MPO levels of the intestinal mucosa were assayed to reflect the free radical formation and neutrophil sequestration, respectively. Thirty-six rats (n = 6) were used to measure blood flow changes of the intestine using 133Xe clearance technique. All data were presented as the mean values plus or minus the standard error of the means (means +/- sem). Although in the R group, mucosal injury score, blood flow, MPO, and MDA levels were higher significantly from the other groups (P < .05), in the RP group blood flow, MPO, and MDA levels were significantly decreased to the basal values (P < .05). Mucosal injury score of the RP group were lower than the reperfusion group but higher than the normal (P < .05). The authors conclude that pentoxifylline pretreatment before reperfusion stabilizes blood flow, decreases MPO and MDA levels to the normal, and attenuates but not completely prevents mucosal damage.

The role of selenium added to pulmonary preservation solutions in isolated guinea pig lungs.

An experimental comparative study on isolated guinea pig lungs has been undertaken to determine the probable beneficial effects of adding selenium to pulmonary preservation solutions in lung ischemia. The isolated lungs (n = 10 in each group) previously being perfused by oxygenated Krebs-Henseleit solution were put in normothermic ischemic conditions just after the infusion of 30 ml of pulmonary preservation solution (Euro-Collins in the control group, Euro-Collins plus selenium 10(-3) mol in the experiment group). After 3 hours of normothermic ischemia the lungs were reperfused with the same buffer for 20 minutes. Pulmonary artery pressures, tissue malondialdehyde levels, and adenosine deaminase levels of the perfusate were measured before and after the ischemic period and also at the end of reperfusion. An electron microscopic analysis was performed on the lung tissues at the end of the experimental procedure. According to our data, the addition of selenium to pulmonary preservation solution showed a significant protective effect regarding both ischemic and reperfusion injury.

The effects of thyroid hormones on the heart following global ischemia. A clinical and experimental study.

Cardiopulmonary bypass is associated with a reduction in plasma thyroid hormone concentrations in patients undergoing cardiac surgery. However, studies of the effects of cardiopulmonary bypass on thyroid function are limited and many studies report conflicting data concerning only the period of cardiopulmonary bypass. In this study, we tried to clinically determine the effects of cardiopulmonary bypass on concentrations of thyroid hormones by comprehensive thyroid function tests in 10 patients before and after surgery, and observed the benefits of triiodothyronine supplementation after global ischemia on myocardial function experimentally in guinea pigs. In patients undergoing surgery, concentrations of total triiodothyronine and free triiodothyronine decreased progressively on the institution of cardiopulmonary bypass and remained below normal levels until 24 hours postoperatively. In the guinea pig hearts studied in a Langendorf perfusion apparatus, T3 supplementation enhanced percentage recovery of ventricular contractile force, heart work and heart rate with respect to other groups receiving no T3 supplementation or T3 supplementation without any ischemic interval.
