An evaluation of quality of life, physical activity level and symptoms in patients with early stages of chronic venous disease.

BACKGROUND: Chronic venous disease (CVD) is a common, long-term disease that has a variety of symptoms, signs and decreases the patients' quality of life (QoL) of the patients. The aim of this study was to evaluate QoL, symptoms, and physical activity level of CVD patients with early stages (C1 and C2 classes). METHODS: The sample of this study composed of 40 patients diagnosed with CVD. The data were collected by face-to-face interview method in the cardiovascular surgery outpatient clinic. Participants were diagnosed with duplex ultrasound (DUS). A personal information form, venous insufficiency epidemiological and economic study-quality of life/symptoms (VEINS-QOL/Sym), and international physical activity questionnaire were used to assess the participants. RESULTS: According to DUS results, 23 participants had unilateral CVD, 17 participants had bilateral CVD. Thirty-six of these limbs were stage C2 according to CEAP, twenty one were stage C3. The patients with CVD had low QoL and physical activity level, also moderate pain intensity. Pain, swelling, restless leg, heavy legs, night cramps, and itching were more common symptoms. There was no statistical difference between unilateral/bilateral CVD patients in QoL scores, physical activity level, and pain intensity (p˃0.05). CONCLUSION: There was no difference between the extent and severity of the disease and QoL, physical activity level, variety of symptoms. To increase the physical activity level and to evaluate the quality of life may be important for the management of the disease from the early stages of the disease (C1 and C2 classes).

Effects of hyperbaric oxygen therapy combined with platelet-rich plasma on diabetic wounds: an experimental rat model.

INTRODUCTION: Hyperbaric oxygen and platelet-rich plasma are used in the treatment of diabetic wounds. The aim of this study is to evaluate the effects of hyperbaric oxygen therapy and autologous platelet concentrates in healing diabetic wounds. MATERIAL AND METHODS: Thirty-six female Wistar albino rats were used in this study. Diabetes mellitus was induced chemically with an intraperitoneal injection of streptozotocin. The rats were divided into a control group, a hyperbaric oxygen group, a platelet-rich plasma group, and a combined therapy group. Platelet-rich plasma was applied just after the creation of the wound; hyperbaric oxygen treatment was carried out daily over 7 days. Wound healing was evaluated according to four parameters: ulcerations, epidermal thickness, density of dermal collagen fibers, and proliferation of dermal blood vessels. RESULTS: The number of active ulcers in the combined therapy group was fewer than in the control group (p = 0.039), and the wound area was greatest in controls (p < 0.001). The epidermal thickness in platelet-rich plasma and combined therapy groups was non-significantly greater than in the control group (p = 0.097 and p = 0.074, respectively). The amount of fibrous collagen in these two groups was greater than in the control group (p = 0.002). CONCLUSIONS: Combined hyperbaric oxygen and platelet-rich plasma therapy was found to be successful in diabetic wound healing. The combination therapy had no additive effect in terms of angiogenesis and the development of new collagen fibers.

Effect of the P2Y12 antagonist ticagrelor on neointimal hyperplasia in a rabbit carotid anastomosis model†.

OBJECTIVES: In the present study, we aimed to deterimine the dose-related effects of ticagrelor, the first reversible inhibitor of the P2Y12 receptor, found in smooth muscle cells as well as platelets, during neointimal hyperplasia in a rabbit carotid anastomosis model. METHODS: This study was an experimental, prospective, randomized controlled study including 20 New Zealand white female rabbits (6-months old; weighing 2300 ± 300 g). Under general anaesthesia, the rabbits underwent transection of the right carotid artery and subsequent anastomosis of both ends. The study animals were divided into the following 4 groups: T1 (ticagrelor 5 mg/kg, orally, daily), T2 (ticagrelor 10 mg/kg, orally, daily), T3 (ticagrelor 20 mg/kg, orally, daily) and control (no ticagrelor treatment). The single oral doses were administered in phosphate-buffered saline. The control group received sterile phosphate-buffered saline (2 ml/kg/day, orally) for 3 weeks postoperatively. At the end of the study, the animals were killed, and the anastomosed segment of the right carotid artery and part of the left carotid artery were excised from each animal. Antibodies against transforming growth factor-ß were used in staining of arterial sections, which was followed by histomorphological and immunohistochemical studies. RESULTS: The median intimal thickness (2.0 ± 0.14 µm left vs 73.4 ± 35.8 µm anastomosed right arteries; P <0.05), the median medial thickness (70.8 ± 5.6 µm left vs 92.3 ± 4.5 µm anastomosed right arteries; P <0.05) and the index ratio of intimal thickness to medial thickness (0.03 ± 0.00 left vs 0.8 ± 0.35 anastomosed control right arteries; P <0.05) increased significantly in the anastomosed right arteries compared with the left carotid arteries in the control group. In the treatment groups, the intimal thickness (73.4 ± 35.8 µm in control group vs T1 32.7 ± 19;1 µm, T2 1.9 ± 0.09 µm and T3 2.2 ± 0.5 µm; P = 0.047, P = 0.009 and P = 0.009, respectively), carotid artery intima/media ratio (0.8 ± 0.35 in control group vs T1 0.4 ± 0.2, T2 0.03 ± 0.01 and T3 0.03 ± 0.01 in ticagrelor groups; P = 0.028, P = 0.009 and P = 0.009, respectively) and medial thickness (92.3 ± 4.5 µm in control group vs T2 65.6 ± 7.1 and T3 66.1 ± 7.6 µm; P = 0.009 and P = 0.009, respectively) decreased significantly in the anastomosed right arteries. CONCLUSIONS: This study indicates that effective doses (10 and 20 mg/kg, daily) of the antiplatelet agent ticagrelor in a rabbit model may be beneficial in prevention of intimal hyperplasia. Restenosis due to intimal hyperplasia has been high. Ticagrelor has also been linked to inhibition of smooth muscle cell proliferation and, hence, reduced intimal hyperplasia.

Comparing the effectiveness of neutrophil-lymphocyte ratio as a mortality predictor on middle and advanced age coronary artery bypass graft patients.

OBJECTIVE: In this study, the effect of neutrophil-lymphocyte ratio (NLR), which is a recently developed inflammatory parameter, as an early stage mortality predictive marker on coronary artery bypass (CABG) patients of various age groups was examined. METHODS: Seventy eight patients under the age of 45 (Group 1) and 80 patients who were older than 45 (Group 2) randomly chosen from the patients who underwent isolated CABG surgery, were examined. The preoperative characteristics and NLRs were noted. The primary end point of the study was determined as all-cause in- hospital mortality. RESULTS: Mortality was observed in 2 patients in Group 1 and 11 patients in Group 2. The threshold value of NLR was 2,47 in the Receiver Operating Characteristic (ROC) curve in Group 1 and there wasn't any significant correlation between preoperative NLR and mortality rates in the patients whose NLRs were above this curve. The threshold value was determined as 4.07 in Group 2 and there was a significant relation between preoperative NLR and mortality (p<0,01). No relation was found between NLR and mortality when all the examined patients were considered (p>0.05). CONCLUSION: NLR that can be easily calculated, can be used as a mortality predictor in the patients of advanced age who will undergo isolated CABG procedure.

Cavitary lung cancer presenting as subcutaneous emphysema on the contralateral side.

Bronchocutaneous fistula is an extremely rare complication of lung cancer and is frequently seen following biopsy or radiotherapy. A 67-year old male patient was administered to our hospital due to sudden onset of shortness of breath and subcutaneous emphysema on the right side. Chest computed tomography revealed a cavitary lesion in the left upper lobe in connection with the subcutaneous emphysema on the right side through sternum and anterior chest wall. The pathological examination of the biopsy performed during tube insertion revealed a well-differentiated squamous cell carcinoma of the lung. The patient was referred for adjuvant therapy to local oncology hospital. He passed away 9 months following diagnosis.
