Recent systematic reviews have concluded that a single session of exercise ameliorates cravings and tobacco withdrawal symptoms; however, smoking behaviour (topography) has not been adequately addressed in the literature. This study examined the effect of an acute bout of exercise on smoking topography following a temporary period of smoking abstinence. Forty-eight adult smokers (Nfemale = 34, Mage = 43.14), who had been smoking for an average of 23.90 years, were randomised to an acute (10 minutes) bout of exercise (N = 23) or passive sitting (control) group. Cigarette cravings were assessed at baseline and immediately pre and post treatment condition during a 15-hour smoking abstinence period. Smoking topography which included puff count, puff volume, puff duration, inter-puff interval, and total cigarette duration was assessed at baseline and post treatment. Although exercise reduced cravings, compared to the control group, smoking topography remained unchanged across time between groups. Furthermore, craving reduction was unrelated to any smoking topography variables. Although there is evidence that exercise can delay time to first cigarette, this study demonstrates that the change to smoking topography is negligible when participants are invited to smoke.

AbstractResearch consistently demonstrates that a bout of moderate exercise alleviates cravings to smoke among abstaining smokers. This pilot study examined the effects of an acute bout of brisk walking on cigarette cravings and smoking topography. Using a within-subject, crossover design, two 10-minute treatment sessions were conducted on separate days by 19 participants(Mage = 24.6 years): passive (i.e., sitting) and brisk walking conditions. Participants rated cravings at baseline, midcondition, and at 0-, 10-, and 20-minutes postcondition and objective measures of smoking topography (puff count, puff duration, puff volume, interpuff interval [IPI], time to first puff [TTFP]) were obtained with the first cigarette smoked postcondition. A 2 (condition) × 4 (time) ANCOVA indicated lower desire to smoke (p< .05) during the walking condition than the passive condition. After the brisk walking condition, a series of ANOVAs demonstrated a significantly increased delay to first puff in comparison to the passive condition. Posthoc analyses (controlling for abstinence period) indicated significant lower puff volume and a trend for shorter puff duration following brisk walking in comparison to the passive sitting condition. A greater reduction in cravings was associated with a longer delay to first puff. In addition to reducing cravings, these results suggest that a bout of brisk walking may also change an individual's smoking behaviour.

The purpose of this study is to extend the literature by examining the effects of an acute bout of moderate to vigorous intensity aerobic exercise on the executive functions of planning and problem solving assessed using a Tower of London Task (TOL Task). Forty-two participants were randomly assigned into either exercise or control group, and performed the TOL Task, before and immediately following exercise or a control treatment. The exercise group performed 30 min of exercise on a stationary cycle at moderate to vigorous intensity while the control group read for the same length of time. Results indicated that the exercise group achieved improvements in TOL Task scores reflecting the quality of planning and problem solving, but not in those reflecting rule adherence and performance speed. These findings indicate that an acute bout of aerobic exercise has facilitative effects on the executive functions of planning and problem solving.

Introduction. Diacutaneous Fibrolysis is defined as specific instrumental intervention to normalize function in the musculoskeletal system. It is considered a treatment method for the mechanical alterations of the locomotor system, and it is widely used in sports for therapeutic and preventive purposes. Despite the clinical benefits observed in different musculoskeletal conditions, the action mechanism of diacutaneous fibrolysis remains uncertain. There are no studies evaluating the neuromuscular response on the posterior muscular chain of the lower extremity in athletes, where overload, stiffness, and injury incidence are high. Objective. To evaluate the immediate, and 30 min post treatment effects of a single diacutaneous fibrolysis session on passive neuromuscular response and mechanosensitibity on hamstring and gluteus in athletes with shortening. Design. A randomized within participant clinical trial. Methods. Sixty-six athletes with hamstring shortening were included (PKE < 160). The lower limbs were randomized between the experimental limb and control limb, regardless of dominance. A single session of diacutaneous fibrolysis was applied to the posterior gluteus maximus, biceps femoris, and semitendinosus of the experimental lower limb whereas the control limb was not treated. Viscoelastic muscle properties (myotonometry), contractile muscle properties (tensomiography), and mechanosensitivity (algometry) were tested before treatment (T0), after treatment (T1), and 30 min post treatment (T2). Results. Regarding viscoelastic properties, in the intra-group analysis we found statistically significant differences in the experimental limb at T1, decreasing muscle stiffness in gluteus maximus (p < 0.042), in biceps femoris (p < 0.001) and in semitendinosus (p < 0.032). We also observed statistically significant differences in Tone decrease (p < 0.011) and relaxation increase (p < 0.001) in biceps femoris. At T2, the decrease in stiffness in all tested muscles was maintained (p < 0.05). There were statistically significant inter-groups differences in stiffness on gluteus (p < 0.048) and biceps femoris (p < 0.019) and in tone on biceps femoris (p < 0.009) compared to the control limb. For contractile properties, we only found statistically significant differences on maximal radial displacement (Dm) in gluteus, both control and experimental at T2 (p < 0.05) and in biceps femoris control (p < 0.030). No changes were found in the mechanosensitivity. Conclusions. A single session of diacutaneous fibrolysis produces changes in some parameters related to viscoelasticity properties of the biceps femoris and gluteus. There were no changes on contractile properties on semitendinosus. Only small changes on the contractile properties on the gluteus maximus and biceps femoris were found. No effect was found on the mechanosensitivity of the posterior chain muscles in athletes with hamstring shortening.

IntroductionOne possible reason for the rapid proliferation of waterpipe (WP) smoking is the pervasive use of flavoured WP tobacco. To begin to understand the impact of WP tobacco flavours, the current study examined the impact of a preferred WP tobacco flavour compared with a non-preferred tobacco flavoured control on user’s smoking behaviour, toxicant exposure and subjective smoking experience.MethodThirty-six current WP smokers completed two, 45-minute ad libitum smoking sessions (preferred flavour vs non-preferred tobacco flavour control) in a randomised cross-over design. Participants completed survey questionnaires assessing subjective smoking experience, exhaled carbon monoxide (eCO) testing, and provided blood samples for monitoring plasma nicotine. WP smoking topography was measured continuously throughout the smoking session.ResultsWhile participants reported an enhanced subjective smoking experience including greater interest in continued use, greater pleasure derived from smoking, increased liking and enjoyment, and willingness to continue use after smoking their preferred WP tobacco flavour (p values <0.05), no significant differences were observed in nicotine and carbon monoxide boost between flavour preparations. Greater average puff volume (p=0.018) was observed during the non-preferred flavour session. While not significant, measures of flow rate, interpuff interval (IPI), and total number of puffs were trending towards significance (p values <0.10), with decreased IPI and greater total number of puffs during the preferred flavour session.DiscussionThe current study is the first to examine flavours in WP smoking by measuring preferred versus control preparations to understand the impact on subjective experience, smoking behaviour and toxicant exposure. The pattern of results suggests that even this relatively minor manipulation resulted in significant changes in subjective experience. These results indicate a possible need for regulations restricting flavours in WP tobacco as with combustible cigarettes.

Recovery of lower extremity (LE) function in chronic stroke patients is considered a barrier to community reintegration. An adequate training program is required to improve neural and functional performance of the affected LE in chronic stroke patients. The current study aimed to evaluate the effect of somatosensory rehabilitation on neural and functional recovery of LE in stroke patients. Thirty male and female patients were recruited and randomized to equal groups: control group (GI) and intervention group (GII). All patients were matched for age, duration of stroke, and degree of motor impairment of the affected LE. Both groups received standard program of physical therapy in addition to somatosensory rehabilitation for GII. The duration of treatment for both groups was eight consecutive weeks. Outcome measures used were Functional Independent Measure (FIM) and Quantitative Electroencephalography (QEEG), obtained pre- and post-treatment. A significant improvement was found in the FIM scores of the intervention group (GII), as compared to the control group (GI) (p < 0.001). Additionally, QEEG scores improved within the intervention group post-treatment. QEEG scores did not improve within the control group post-treatment, except for “Cz-AR”, compared to pretreatment, with no significant difference between groups. Adding somatosensory training to standard physical therapy program results in better improvement of neuromuscular control of LE function in chronic stroke patients.

Abstract Background Acute pulmonary thromboembolism is the most dangerous presentation of venous thromboembolic disease. The role of thrombolysis in massive pulmonary embolism has been studied extensively, but the same is not there for submassive pulmonary embolism. This study is aimed at evaluating the effects of thrombolysis in acute submassive pulmonary embolism. This was a prospective, case-control, observational study. Patients presenting with acute submassive pulmonary embolism were divided into thrombolysis group and control group depending on whether they received thrombolysis plus anticoagulation or anticoagulation only, respectively. Results A total of 86 patients were included in the study. Forty-two patients were in the thrombolysis group, and 44 patients were in the control group. The mean ± SD age in the control and thrombolysis groups was 63.3 ± 14.7 and 56.4 ± 13.8 years, respectively. The two groups were well matched in sex distribution and associated comorbidities like COPD, active surgery, major trauma, and immobilization. On echocardiography, dilated RA/RV in pre-treatment vs. post-treatment was seen in 20 (45.5%) vs. 20 (45.5%) in the control group and 26 (61.9%) vs. 11 (26.2%) in the thrombolysis group. Similarly, RV systolic dysfunction in pre-treatment vs. post-treatment was seen in 24 (54.5%) vs. 21 (47.7%) in the control group and 22 (52.4%) vs. 8 (19.0%) in the thrombolysis group. Pulmonary artery pressure in pre-treatment vs. post-treatment was 64.4 ± 15.0 vs. 45.9 ± 9.9 mmHg in the control group and 68.3 ± 17.4 vs. 31.4 ± 6.9 mmHg in the thrombolysis group. In control vs. thrombolysis group, there were 5 vs. 1 death, 6 vs. 1 hemodynamic decompensation, and 6 vs. 1 patient needing mechanical ventilation. Conclusion Thrombolysis in submassive pulmonary embolism is associated with better right ventricular functions, lower pulmonary artery pressures, and comparable mortality rates.

Objective. To examine the effect of acute and short-term (~1 week) aerobic exercise training on plasma adiponectin levels in inactive, abdominally obese men.Materials and Methods. Inactive and abdominally obese men (n=38, waist circumference ≥102 cm) recruited from Kingston, Canada were randomly allocated to perform three bouts of aerobic treadmill exercise at either low (50% VO2peak) or high (75% VO2peak) intensity during a 1-week period. Blood samples were taken before and after the first exercise session and 24–72 hours following the completion of the final exercise session.Results. Adiponectin levels were elevated immediately following an acute bout of exercise at both high and low intensities (High:5.79±0.42versus5.05±0.41 ug/mL; Low:5.24±0.44versus4.37±0.44 ug/mL,P<0.05) and remained elevated following 30 minutes of rest. In comparison to baseline, adiponectin levels were also elevated 24–72 hours following the final exercise session (High:5.47±0.48versus4.88±0.48 ug/mL; Low:5.18±0.49versus4.47±0.49 ug/mL,P<0.05).Conclusion. Both acute and short-term aerobic exercise result in a significant increase in plasma adiponectin levels in inactive, abdominally obese men independent of intensity.

AbstractPositive effects of exercise on cancer prevention and progression have been proposed to be mediated by stimulating natural killer (NK) cells. Because NK cell receptors are regulated by epigenetic modifications, we investigated whether acute aerobic exercise and training change promoter DNA methylation and gene expression of the activating KIR2DS4 and the inhibiting KIR3DL1 gene. Sixteen healthy women (50–60 years) performed a graded exercise test (GXT) and were randomized into either a passive control group or an intervention group performing a four-week endurance exercise intervention. Blood samples (pre-, post-GXT and post-training) were used for isolation of DNA/RNA of NK cells to assess DNA promoter methylation by targeted deep-amplicon sequencing and gene expression by qRT-PCR. Potential changes in NK cell subsets were determined by flow cytometry. Acute and chronic exercise did not provoke significant alterations of NK cell proportions. Promoter methylation decreased and gene expression increased for KIR2DS4 after acute exercise. A high gene expression correlated with a low methylation of CpGs that were altered by acute exercise. Chronic exercise resulted in a minor decrease of DNA methylation and did not alter gene expression. Acute exercise provokes epigenetic modifications, affecting the balance between the activating KIR2DS4 and the inhibiting KIR3DL1, with potential benefits on NK cell function.

Objective: We aimed to investigate how EEG frequency bands change in females in response to acute exercise compared to males.Methods: Consenting healthy adult females (n=15) & males (n=15) bicycled an ergometer at 50% HRmax for 20 min. EEG was recorded using 10-20 system from mid-frontal (F4 & F3), central (C4 & C3), parietal (P4 & P3), temporal (T4 & T3) & occipital (O2 & O1) regions. Exercise-induced EEG changes were compared between two sexes by Mann Whitney test. EEG power (μV2) is presented as median & interquartile range.Results: In females, as compared to males, resting right side delta, alpha, and beta activities were more in almost all recorded sites [delta: F4= 49.82 (44.23-63.56) vs. 35.5 (32.70-44.44), p < 0.001; etc], [alpha F4: 127.62 (112.89-149.03) vs. 49.36 (46.37-52.98), p < 0.001; etc], [beta F4= 18.96 (15.83-25.38)  vs. 14.77 (10.34-17.55), p < 0.05; C4= 21.16 (18.4-25.9) vs. 15.48 (9.66-19.40), p < 0.01; etc]. Similarly, females resting right theta activity was more in parietal [P4= 33.04 (25.1-42.41) vs. 22.3 (18.36-34.33), p < 0.05] & occipital [O2= 50.81 (30.64-66.8) vs. 26.85 (22.18-34.42), p < 0.001] regions than in males. They had similar picture on the left side also. The delta values of right alpha power was less in female in frontal [F4= -11.61 (-45.24 -3.64) vs. 9.48 (1.05-16.58), p < 0.01] and central [C4= -72 (-32.98-9.48) vs. 22.69 (13.03-33.05), p < 0.01] regions compared to males. Also, they had less delta values of left central alpha [C3= -8.32 (-32.65-6.1) vs. 16.5 (0.36-36.36), p < 0.01] and temporal beta [T3= -6.29 (-10.09- -1.49) vs. 1.24 (-0.84- 2.8), p < 0.001] power compared to males.Conclusion: At rest females may have high EEG powers in different bands. In response to acute exercise, they respond in reverse way as compared to males.DOI: http://dx.doi.org/10.3126/ajms.v6i2.11116Asian Journal of Medical Sciences Vol.6(2) 2015 30-35
