Summary: Background: Catamenial pneumothorax is an uncommon form of spontaneous pneumothorax in women. The exact epidemiology and pathogenesis remain elusive. Video-assisted thoracoscopic surgery is used for diagnostic and therapeutic purposes. Summary: Objective: The aim of this review was to analyze the demographic features, intraoperative findings, treatment methods and outcome in catamenial pneumothorax patients. In addition, we assessed the relationship between catamenial pneumothorax and pelvic endometriosis. Summary: Search strategy: A PubMed search of medical literature, published from January 1993 (video-assisted thoracoscopic surgery first described in literature) to January 2015, using the keywords “catamenial pneumothorax” was performed. Our study complied with the preferred reporting of items for systematic reviews and meta-analysis principles. A total of 182 patients were included in the analysis, including 4 patients treated at our institution. Summary: Selection criteria: The inclusion criteria of were recurrent (at least two) episodes of spontaneous pneumothorax in relation to onset of menses. Summary: Data selection and analysis: Age at time of diagnosis, side affected, diagnosis of pulmonary endometriosis, intraoperative findings, histological confirmation of thoracic endometriosis, methods of treatment and outcome were recorded. Summary: Main results: In 2.9% of the patients no pathological lesions were found; however, 59.3% had endometrial implants and 57.0% diaphragmatic perforations. Pelvic endometriosis was reported in 39.5% patients. Patients with diagnosed pelvic endometriosis showed a significantly higher rate of endometrial implants and histologically confirmed endometriosis lesions than patients without pelvic endometriosis. In 26.9% of patients, recurrence was observed after treatment. Summary: Conclusion: Video-assisted thoracoscopic surgery provides good diagnostic and therapeutic results; however, 25% of patients experienced recurrence despite adequate treatment. A strong association exists between thoracic and pelvic endometriosis in catamenial pneumothorax patients. © 2017 Springer-Verlag GmbH Austria

Objectives: The aim of our study was to investigate the relationship between genetic polymorphisms in the mitochondrial thioredoxin reductase 2 (TrxR2) and myocardial infarction (MI) in subjects with type 2 diabetes mellitus (T2DM) of Slovenian origin. Methods: The study population consisted of 972 Caucasian subjects with T2DM of more than 10 years' duration: 161 patients with MI and 811 patients with no history of coronary artery disease. Polymorphisms in thioredoxin reductase 2 (. TXNRD2) gene, rs1548357, rs4485648, and rs5748469, were studied. Results: Individuals carrying CC + CT genotypes of rs1548357 TXNRD2 polymorphism had lower prevalence of MI compared with TT genotype group (41.6% vs 52.8%, OR = 0.589, 95% CI = 0.368-0.942, P=. 0.027). Conclusions: The TXNRD2 rs 1548357 polymorphism might be a genetic risk factor for MI in subjects with T2DM of Slovenian origin. © 2015 Elsevier Ireland Ltd.

Purpose The objective was to determine the separate and combined effects of hypoxia and inactivity/unloading on sleep architecture during a 10-day period of confinement. Methods Ten subjects participated in three 10-day trials in random order: hypoxic ambulatory (HAMB), hypoxic bedrest (HBR), and normoxic bedrest (NBR). During the HAMB and HBR trials, subjects were confined to a hypoxic facility. The hypoxia profile was: simulated altitude of 2,990 m on day 1, 3,380 m on day 2, and 3,881 m on day 3. In the NBR and HBR trials, subjects maintained a horizontal position throughout the confinement period. During each trial, sleep polysomnography was conducted one night prior to (baseline; altitude of facility is 940 m) and on the first (NT1, altitude 2,990 m) and tenth (NT10, altitude 3,881 m) night of the 10-day intervention. Results Average time in sleep stage 1 decreased from NT1 to NT10 irrespective of trial. Overall incidence and time spent in periodic breathing increased from NT1 to NT10 in both HAMB and HBR. During NT1, both HAMB and HBR reduced slow-wave sleep and increased light sleep, whereas NBR and HBR increased the number of awakenings/night. There were fewer awakenings during HAMB than NBR. Conclusions Acute exposure to both hypoxia and bedrest (HBR) results in greater sleep fragmentation due to more awakenings attributed to bedrest, and lighter sleep as a result of reduced slow wave sleep caused by the hypoxic environment. © 2014 Springer-Verlag Berlin Heidelberg.

Background: We attempted to identify possible differences in the contractility of the gastrocnemius medialis (GM) muscle between healthy controls and individuals with peripheral arterial disease (PAD) and intermittent lower-limb claudication. Methods: The GM muscles of 17 PAD patients and 17 healthy controls were examined with tensiomyography. Single or multiple electrical impulses were used to trigger muscle contractions, and the time and amplitude of contractions were measured. Results: After single-impulse stimulation, the GM muscles of PAD patients showed significantly shorter contraction times (P < 0.001) than the GM muscles of controls. During 1 min of repetitive electrical stimulation, the contraction velocity of the controls' GM muscles typically showed a sustained increase throughout the stimulation period, whereas in PAD patients, a significant decrease in contraction velocity was observed after 30 s. The onset of muscle fatigue was unrelated to the ankle brachial index (ABI) of the examined leg. When the legs of PAD patients with higher and lower ABIs were compared to each other, no significant differences were found regarding the time and amplitude of contraction after single-impulse stimulation. Conclusions: The GM muscles of individuals with intermittent claudication contract more quickly and fatigue earlier than the GM muscles of healthy controls. Because the contraction time, measured with tensiomyography, reflects the individual's muscle fibre composition, our findings may reflect a shift from type I fibres to type II fibres in the GM muscles of PAD patients. Our data support the idea that calf myopathy is present in claudication-prone patients and, in part, determines the clinical manifestations of PAD. © 2012 European Society for Vascular Surgery.

Purpose: Aerobic training accelerates Heart Rate Recovery after exercise in healthy subjects and in patients with coronary disease. As shown by pharmacological autonomic blockade, HRR early after exercise is dependent primarily on parasympathetic reactivation. Thus, accelerated HRR early after exercise in endurance-trained athletes may be attributed to augmented parasympathetic reactivation. In the present study, we tested the hypothesis that the HRR early after submaximal exercise is related to the pre-exercise parasympathetic modulation. Methods: Thirty endurance-trained athletes (20 males, 50 ± 7 years) and thirty control subjects (20 males, 52 ± 6 years) performed a submaximal exercise on a cyclo-ergometer. Pre-exercise resting short-term heart rate variability (HRV) parameters in time and frequency-domains were correlated with HRR during the first 30 s, 1 and 2 min after cessation of exercise. Results: We found that HRR was statistically significantly faster in athletes than in controls at all examination time points (p < 0.05). HF, SDNN and RMSSD were statistically significantly higher in athletes than in controls (p < 0.05), but other resting HRV parameters were not statistically different between groups. After 30 s, 1 and 2 min of recovery, HRR correlation with total power, HF, HFnu and RMSSD was positive, while the correlation with LF/HF was negative for small and positive for larger values. The opposite was true for SDNN. Conclusions: These findings support the hypothesis that HRR early after submaximal exercise is related to resting parasympathetic modulation in the middle-aged subjects. In addition, they suggested an optimal range of HRV for maximal HRR after exercise. © 2014 Springer-Verlag Berlin Heidelberg.

This report provides a summary of the 2013 Slovenian renal replacement therapy (RRT) data, obtained from 24 renal centers: 23 dialysis and one transplant center, referring from 31 December 2013, with 100% response rate to individual patient questionnaires. Slovenia had a population of 2061085 on 1 January 2014. The total number of patients treated by RRT was 2077, i.e. 1008.3 per million of population (pmp); 1349 (65%) were treated by hemodialysis, 52 (2.5%) by peritoneal dialysis, and 676 (32.5%) had a functioning kidney graft. A total of 260 incident patients, 126.2 pmp (at day one), started RRT, their median age was 69years, 59.8% were men,. 58.5% of hemodialysis patients were treated with on-line hemodiafiltration. Vascular access was arteriovenous fistula in 79%, polytetrafluoroethylene graft in 8%, and catheter in 13% of patients, mean blood flow 27641mL/min, 5.5% dialyzed in a single-needle mode. The crude death rate was 11.4% in all RRT patients (incident patients day 1 included, 15.9% in hemodialysis, 12.3% in peritoneal dialysis, 2.1% in transplant recipients). 60 kidney transplantations were performed in 2013, from deceased donors.

This investigation aimed to compare the response of young and older adult men to bed rest (BR) and subsequent rehabilitation (R). Sixteen older (OM, age 55-65 yr) and seven young (YM, age 18-30 yr) men were exposed to a 14-day period of BR followed by 14 days of R. Quadriceps muscle volume (QVOL), force (QF), and explosive power (QP) of leg extensors; single-fiber isometric force (Fo); peak aerobic power (Vo2peak); gait stride length; and three metabolic parameters, Matsuda index of insulin sensitivity, postprandial lipid curve, and homocysteine plasma level, were measured before and after BR and after R. Following BR, QVOL was smaller in OM (-8.3%) than in YM (-5.7%,P= 0.031); QF (-13.2%,P= 0.001), QP (-12.3%,P= 0.001), and gait stride length (-9.9%,P= 0.002) were smaller only in OM. Fo was significantly smaller in both YM (-32.0%) and OM (-16.4%) without significant differences between groups. Vo2peakdecreased more in OM (-15.3%) than in YM (-7.6%,P< 0.001). Instead, the Matsuda index fell to a greater extent in YM than in OM (-46.0% vs. -19.8%, respectively,P= 0.003), whereas increases in postprandial lipid curve (+47.2%,P= 0.013) and homocysteine concentration (+26.3%,P= 0.027) were observed only in YM. Importantly, after R, the recovery of several parameters, among them QVOL, QP, and Vo2peak, was not complete in OM, whereas Fo did not recover in either age group. The results show that the effect of inactivity on muscle mass and function is greater in OM, whereas metabolic alterations are greater in YM. Furthermore, these findings show that the recovery of preinactivity conditions is slower in OM.

Aging and experimental bed rest are associated with muscle atrophy and resistance to post-prandial stimulation of protein synthesis or anabolic resistance (AR). We have used in young and older adult volunteers, during short-term bed rest, a quick and non-invasive method, based on a single oral bolus of the stable isotope L[ring-We compared in older (O, 591y) and young (Y, 231y) healthy male volunteers the effects of two-week bed rest on post-prandial protein kinetics, assessed during absorption of a standard ready-to-use oral nutritional supplement, through stable-labeled isotope amino acid DAt baseline, in pooled Y and O subjects, values of AR were inversely correlated with QMV (R=-0.75; p<0.03). Following 2-weeks of inactivity, there were significant bed rest effects on AR (p<0.01) and QMV (p<0.03), as well as significant bed restgroup interaction for AR (p<0.03;+9.2% in Y;+21.9% in O) and QMV (p<0.05;-5.7% in Y;-%7.3 in O). In pooled subjects, the percentage delta changes in AR and QMV, induced by bed rest, were inversely correlated (R=-0.57; p<0.05).Bed rest-induced AR is much greater in the older than in younger adults. We have developed a new, simple, non-invasive method for the assessment of AR. The results indicate that this metabolic abnormality is a key mechanism for sarcopenia of aging and inactivity.
