OBJECTIVE: The main causes of spinal cord ischemia are a variety of vascular pathologies causing acute arterial occlusions. We investigated neuroprotective effects of kefir on spinal cord ischemia injury in rats. METHODS: Rats were divided into three groups : 1) sham operated control rats; 2) spinal cord ischemia group fed on a standard diet without kefir pretreatment; and 3) spinal cord ischemia group fed on a standard diet plus kefir. Spinal cord ischemia was performed by the infrarenal aorta cross-clamping model. The spinal cord was removed after the procedure. The biochemical and histopathological changes were observed within the samples. Functional assessment was performed for neurological deficit scores. RESULTS: The kefir group was compared with the ischemia group, a significant decrease in malondialdehyde levels was observed (p<0.05). Catalase and superoxide dismutase levels of the kefir group were significantly higher than ischemia group (p<0.05). In histopathological samples, the kefir group is compared with ischemia group, there was a significant decrease in numbers of dead and degenerated neurons (p<0.05). In immunohistochemical staining, hipoxia-inducible factor-1alpha and caspase 3 immunopositive neurons were significantly decreased in kefir group compared with ischemia group (p<0.05). The neurological deficit scores of kefir group were significantly higher than ischemia group at 24 h (p<0.05). CONCLUSION: Our study revealed that kefir pretreatment in spinal cord ischemia/reperfusion reduced oxidative stress and neuronal degeneration as a neuroprotective agent. Ultrastructural studies are required in order for kefir to be developed as a promising therapeutic agent to be utilized for human spinal cord ischemia in the future.

BACKGROUND: Anxiety sensitivity (AS) is a continuous fundamental fear and defined as extreme fear of anxiety sensations and symptoms. High AS can cause tendency to anxiety disorders. There are many studies evaluating the anxiety in patients with acne; however, AS has not been investigated. OBJECTIVE: We aimed to investigate AS in patients with acne. METHODS: Two hundred and fourteen acne patients and 117 healthy control subjects, aged older than 16 years were enrolled in the study. Severity of acne was evaluated by Global Acne Grading System. The acne patients and healthy controls were asked to complete the anxiety sensitivity index-3 (ASI-3), the Beck anxiety inventory (BAI) and the Turkish version of acne quality of life index. RESULTS: Anxiety and AS levels in acne patients were significantly higher than healthy controls (p<0.001). Quality of life was impaired in acne patients. Quality of life was negatively correlated with anxiety and AS levels in acne patients (p=0.014, p=0.019, respectively). There was no correlation between quality of life and disease severity (p=0.556) and also there was no correlation between psychiatric scale scores (ASI-3, BAI) and disease severity (p=0.147, p=0.871, respectively). CONCLUSION: To our knowledge, our study is the first to report that AS is high in acne patients. Clinically, our results suggest that there might be a relationship between AS and acne. We conclude that further studies are needed in order to clarify the relationship between acne and AS and to investigate the efficacy of cognitive behavioral treatments in acne patients.

BACKGROUNDSome research exists on the effect of non-pharmacological approaches for labor pain relief. However, there is limited information about effectiveness of breathing exercises in pregnant women to reduce maternal pain during labor.

OBJECTIVETo determine whether breathing exercises for pregnant women during the second stage of labor have beneficial effects on maternal pain, duration of labor, and the first-minute Appearance, Pulse, Grimace, Activity and Respiration (APGAR) scores.

DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONSThis randomized clinical trial involved 250 pregnant women, who were randomly divided into two groups: intervention group (IG; n = 125) and control group (CG; n = 125). IG received one session breathing exercise training and performed breathing exercises during the second stage of labor versus the CG that did not receive any breathing exercise training.

MAIN OUTCOME MEASURESThe effects of breathing exercises on maternal pain were determined by Visual Analogue Scale (VAS), duration of the second stage of labor, and the first-minute APGAR scores.

RESULTSThe mean age of the participants was (23.2 ± 4.2) (range: 18 to 42) years. Both IG and CG had similar baseline characteristics in terms of age, education level, occupation, and smoking (P > 0.05). The mean VAS scores of IG and CG were (88.2 ± 6.3) and (90.5 ± 7.0), respectively (P < 0.001). The duration of the second stage of labor was (369.6 ± 92.0) s for IG and (440.7 ± 142.5) s for CG (P < 0.001). The mean first-minute APGAR scores were (8.84 ± 0.50) for IG and (8.73 ± 0.89) for CG (P > 0.05).

CONCLUSIONBased on this study, breathing exercises with deep inhalation and exhalation in pregnant women are effective in reducing the perception of labor pain and shortening the duration of the second stage of delivery. Therefore, we recommend breathing exercises as an effective modality for labor pain management and shortening the duration of labor.
