We report a 43-year-old woman who died after 18 years history of parkinsonism. She was well until 25 years of the age (1976) when she noted a difficulty in stepping her feet. In the next year, she started to drag her feet. She was treated with levodopa with good response, however, she developed dyskinesia when she was 33 years of the age. She was evaluated in another hospital in 1984. She showed normal intelligence, normal ocular movement, masked face, small voice, small step gait, stooped posture, freezing of the gait, retropulsion, and cogwheel rigidity in limbs. No tremor or ataxia was noted. She received left ventrolateral thalamotomy at that time. Rigidity on the right side markedly reduced, however, she continued to show bradykinesia and motor fluctuations. On August 1 of 1994, she developed fever of 40 degrees C and dyspnea. On the next day, she expired from acute respiratory distress. She was able to walk unsupported until just before her last admission. The patient was discussed in a neurological CPC. The chief discussant arrived at the conclusion that this patient had Lewy body-positive young onset Parkinson's disease. Opinions were divided into two groups, i.e., young onset Lewy-body positive Parkinson's disease and Lewy-body negative young onset parkinsonism. Post-mortem examination revealed moderate loss of pigmented neurons in the substantia nigra more in the ventro-lateral part. Lewy bodies were found in the remaining neurons. Lewy bodies were more frequently seen in the locus coeruleus, although neuronal loss was less prominent in the locus coeruleus. The dorsal vagal motor nucleus showed moderate loss of neurons. Otherwise, the central nervous system was unremarkable. To our knowledge, this patient had the second youngest age of the onset so far reported in the literature for Lewy-body positive typical Parkinson's disease.

A 22-year-old woman presented to the emergency room of a local hospital with pleuritic chest pain. She regularly worked out and admitted to taking performance-enhancing drugs (PEDs). Clinical findings and further diagnostic work up revealed a diagnosis of perimyocarditis, and adequate therapy was initiated. During the course of the first day, the patient had to be intubated and mechanically ventilated. A diagnosis of bilateral pneumonia and acute respiratory distress syndrome (ARDS) due to an infection by rhinovirus spp was made. A smoking habit, the intense physical training and the use of PED's may have exacerbated the course of the viral pneumonia. After 12 days the patient could be extubated. The length of stay in the intensive care unit was 16 days. After hospital discharge, the patient went to a pulmonary rehabilitation facility for 2 weeks. The outcome was favourable and the patient resumed her strength and endurance training. 2016 BMJ Publishing Group Ltd.

A 73-year-old woman presented with a six-day history of abdominal pain that had started in the epigastrium, but recently had become more intense in the right lower quadrant. Peptic ulcer had been diagnosed three years prior to presentation and had been managed medically. On physical examination, epigastric tenderness as well as guarding and rebound tenderness in the right lower quandrant were present. Mild leukocytosis was reported. Computed tomography demonstrated a 5-cm retrocecal mass with low attenuation (fluid content) surrounded by an irregularly thickened uncalcified wall. Multiple areas of tissue debris were seen extending into the mass, but no true separation was present

Life-long regular endurance exercise yields positive effects on cardiovascular and metabolic function, disease and mortality rate. Glycation may be a major mechanism behind age-related diseases. However, it remains unknown if skin autofluorescence (SAF), which reflects glycation, is related to arterial and metabolic function in life-long endurance runners and sedentary controls. Healthy elderly men: 15 life-long endurance runners (OT) (64±4years) and 12 old untrained (OU) (66±4years), and healthy young men; ten young athletes (YT) (26±4years) matched to OT for running distance, and 12 young untrained (YU) (24±3years) were recruited. Endothelial function (reactive hyperemia index, RHI) and arterial stiffness (augmentation index, AI@75 and AI) were measured by an operator-independent PAT 2000. SAF was non-invasively determined using an autofluorescence spectrometer. For AI@75 there was an effect of age (page correction (both r 2 =0.19, paging and pathology). Surprisingly, endurance running only had modest effects on cardiovascular function compared to lean healthy controls. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective: To investigate the late effect of radiation on child-bearing women, through observing 'Fang', a 19-week-pregnant woman at age of 23, who was exposed to 60 Co radiation in Shanxi Xinzhou radiation accident in November, 1992 and diagnosed as moderate bone marrow type acute radiation sickness and recovered after 16 year of follow-up treatment. Methods: Clinical data including medical history, physical examination, laboratory data, imaging findings and consulting relevant departments were reviewed. Results: The followed-up woman 'Fang' often felt weak and caught cold after recovery. When she was 32 years old (9 years after radiation), her hair turned grey, but without hair loss. Her menstrual quantitiy was lessened since 31 years old (8 years after radiation). She was remarried and pregnant twice in the same year. At the first time she underwent artificial abortion and the second child suffered from intrauterine death after 6 months of pregnancy. The physical examination found bilateral degree I thyroid enlargement and sparse armpit hair. The laboratory test showed the increased levels of triiodothyronine, thyroxine and anti-thyroid peroxidase antibody (TMAb) and the decreased thyroid stimulating hormone (TSH). Unstable chromosome aberrations were totally lost and stable aberrations in chromosomes were detected by fluorescence in situ hybridization (FISH). The dose estimated with the residue chromosome aberration was 0.76 Gy. Other laboratory results were normal. Ultrasonic test showed diffuse lesion in bilateral thyroid and multiple cystic nodules in right lobe of thyroid, which was considered to be nodular goiter. The examination of bone mineral density (BMD) showed osteoporosis from the second to the fourth lumber vertebra. There were no diseases associated with radiation based on the consultation from related departments. Conclusions: Intrauterine death after 6 months of pregnancy might be associated with the previous exposure. There is no evidence of

Failure to thrive (FTT) is a state of overall decline. Patients often present with weight loss, poor appetite, malnutrition, and decreased physical functioning. The etiology is multifactorial including chronic diseases, functional impairments, and acute illnesses. Evaluation for reversible causes is paramount, and treatment is aimed at maintaining or improving functional status. We present a case of a 91-year-old woman with a retroperitoneal mass that was found on workup for failure to thrive.

Full Text Available Markedly elevated androgen levels can lead to clinical virilization in females. Clinical features of virilization in a female patient, in association with biochemical hyperandrogenism, should prompt a search for an androgen-producing tumor, especially of ovarian or adrenal origin. We herein report the case of a 60-year-old woman of Pakistani origin who presented with the incidental finding of male pattern baldness and hirsutism. Her serum testosterone level was markedly elevated at 21 nmol/L (normal range: 0.4–1.7 nmol/L, while her DHEAS level was normal, indicating a likely ovarian source of her elevated testosterone. Subsequently, a CT abdomen-pelvis was performed, which revealed a bulky right ovary, confirmed on MRI of the pelvis as an enlarged right ovary, measuring 2.9 × 2.2 cm transaxially. A laparoscopic bilateral salpingo-oophorectomy was performed, and histopathological examination and immunohistochemistry confirmed the diagnosis of a Leydig cell tumor, a rare tumor accounting for 0.1% of ovarian tumors. Surgical resection led to normalization of testosterone levels.

To describe training variations across the annual cycle in Olympic and World Champion endurance athletes, and determine whether these athletes used tapering strategies in line with recommendations in the literature. Eleven elite XC skiers and biathletes (4 male; 28±1 yr, 85±5 mL x min(-1) x kg(-1) VO2max, 7 female, 25±4 yr, 73±3 mL x min(-1) x kg(-1) VO2max) reported one year of day-to-day training leading up to the most successful competition of their career. Training data were divided into periodization and peaking phases and distributed into training forms, intensity zones and endurance activity forms. Athletes trained ∼800 h/500 sessions x year(-1), including ∼500 h x year(-1) of sport-specific training. Ninety-four percent of all training was executed as aerobic endurance training. Of this, ∼90% was low intensity training (LIT, below the first lactate threshold) and 10% high intensity training (HIT, above the first lactate threshold) by time. Categorically, 23% of training sessions were characterized as HIT with primary portions executed at or above the first lactate turn point. Training volume and specificity distribution conformed to a traditional periodization model, but absolute volume of HIT remained stable across phases. However, HIT training patterns tended to become more polarized in the competition phase. Training volume, frequency and intensity remained unchanged from pre-peaking to peaking period, but there was a 32±15% (Pphase. The annual training data for these Olympic and World champion XC skiers and biathletes conforms to previously reported training patterns of elite endurance athletes. During the competition phase, training became more sport-specific, with 92% performed as XC skiing. However, they did not follow suggested tapering practice derived from short-term experimental studies. Only three out of 11 athletes took a rest day during the final 5 days prior to their most successful competition.

To determine whether long-term very vigorous endurance training prevents hypertension. Cohort study of master orienteering runners and controls. Finland. In 1995, a health questionnaire was completed by 264 male orienteering runners (response rate 90.4%) who had been top-ranked in competitions among men aged 35-59 years in 1984, and by 388 similarly aged male controls (response rate 87.1%) who were healthy at the age of 20 years and free of overt ischemic heart disease in 1985. Self-report of medication for hypertension. In the endurance athlete group, the crude prevalence (8.7%) of subjects who had used medication for hypertension was less than a third of that in the control group (27.8%). Even after adjusting for age and body mass index, the difference between the groups was still significant (odds ratio for athletes 0.43, 95% confidence interval 0.25-0.76). Long-term vigorous endurance training is associated with a low prevalence of hypertension. Some of the effect can be explained by a lower body mass, but exercise seems to induce a lower rate of hypertension by other mechanisms than by decreasing body weight

Autoimmune Polyendocrine Syndrome 3 Onset with Severe Ketoacidosis in a 74-Year-Old Woman

2015-01-01

Full Text Available Type 1 diabetes mellitus (T1D, autoimmune thyroid disease, and autoimmune gastritis often occur together forming the so-called autoimmune polyendocrine syndrome type 3 (APS3. We here report a clinical case of a 74-year-old woman who presented for the first time with severe hyperglycemia and ketoacidosis diagnosed as T1D. Further clinical investigations revealed concomitant severe hypothyroidism with autoimmune thyroid disease and severe cobalamin deficiency due to chronic atrophic gastritis. The diagnosis of type 1 diabetes mellitus was confirmed by the detection of autoantibodies against glutamic acid decarboxylase 65, islet cell antibodies, and anti-insulin autoantibodies. Anti-thyroperoxidase, anti-thyroglobulin, and anti-gastric parietal cell antibodies were also clearly positive. The case emphasized that new onset diabetic ketoacidosis, hypothyroidism, and cobalamin deficiency may simultaneously occur, and one disease can mask the features of the other, thereby making diagnosis difficult. It is noteworthy that an APS3 acute episode occurred in an asymptomatic elder woman for any autoimmune diseases.

Tetralogy of Fallot is the most common cyanotic congenital heart defect, affecting approximately 2700 infants per year born in the United States. The natural history of the tetralogy reflects the adverse physiologic consequences of the underlying structural abnormalities, with only approximately 3% of uncorrected patients surviving past age 40. In this case report, we report an 87-year-old woman with unoperated tetralogy of Fallot, who we believe to be the oldest and only second octogenarian described in the literature. PMID:22470677

Full Text Available The patient was a 41 year old woman that was brought to the emergency department (ED by her husband following seizure. According to the relatives accompanying her, the seizure was of tonic-clonic type, had occurred one hour before presentation to ED, and had lasted 3 minutes. The patient had been drowsy for about 15 minutes after the end of the seizure. She had no history of head trauma and did not mention headache, nausea and vomiting, fever, vision problems or others. On presentation, amnesia regarding the things that happened was evident. In her history, she had a generalized tonic-clonic seizure 4 years back, regarding which she had not done proper follow up for taking necessary diagnostic measures and had not been treated with anti-epileptic medication. She had a history of surgery for removing cold thyroid nodule 20 years ago and was under calcium treatment for 15 years but she had decided to stop taking her medications since 5 year ago. She did not have a history of alcohol or drug abuse. The patient was conscious and awake on presentation and did not have any specific clinical complaints. Her vital signs on presentation were as follows:Blood Pressure = 120/70mmHg, Pulse Rate = 68/minute, Respiratory Rate = 16/minute, O2saturation= 98% at air room, Oral Temperature= 37°C, and bedside blood sugar in the normal range.In head and neck examination, the surgery scar was seen in the thyroid region. Examination of the thyroid also showed a nodular surface in palpation. Examination of the heart, lungs, abdomen and extremities did not have pathologic findings. Neurologic examinations including evaluation of cranial nerves, sense and power of the muscles, cerebellar examination and deep tendon reflexes were normal. Based on the opinion of the in-charge physician, anti-epileptic drugs were not prescribed at this stage.

2017-03-01

This study investigated the reliability of static and dynamic handgrip strength endurance using different protocols and indicators for the assessment of strength endurance. Forty young, healthy men and women (age, 18-22 years) performed 2 handgrip strength endurance protocols: a static protocol (sustained submaximal contraction at 50% of maximal voluntary contraction) and a dynamic one (8, 10, and 12 maximal repetitions). The participants executed each protocol twice to assess the test-retest reproducibility. Total work and total time were used as indicators of strength endurance in the static protocol; the strength recorded at each maximal repetition, the percentage change, and fatigue index were used as indicators of strength endurance in the dynamic protocol. The static protocol showed high reliability irrespective of sex and hand for total time and work. The 12-repetition dynamic protocol exhibited moderate-high reliability for repeated maximal repetitions and percentage change; the 8- and 10-repetition protocols demonstrated lower reliability irrespective of sex and hand. The fatigue index was not a reliable indicator for the assessment of dynamic handgrip endurance. Static handgrip endurance can be measured reliably using the total time and total work as indicators of strength endurance. For the evaluation of dynamic handgrip endurance, the 12-repetition protocol is recommended, using the repeated maximal repetitions and percentage change as indicators of strength endurance. Practitioners should consider the static (50% maximal voluntary contraction) and dynamic (12 repeated maximal repetitions) protocols as reliable for the assessment of handgrip strength endurance. The evaluation of static endurance in conjunction with dynamic endurance would provide more complete information about hand function. Copyright © 2017 American Society for Surgery of the Hand.

Year of the Woman, Decade of the Man: trajectories of growth in women's state legislative representation.

Science.gov (United States)

Paxton, Pamela; Painter, Matthew A; Hughes, Melanie M

2009-03-01

The expansion of women's political representation ranks among the most significant trends in American politics of the last 100 years. In this paper, we develop two longitudinal theories to explain patterns of growth and change in women's state legislative representation over time. Gender salience suggests that years in which women's absence from politics is problematized (e.g., 1992-the Year of the Woman) will demonstrate higher levels of growth. Political climate suggests that periods in which domestic issues are stressed (e.g., the 1990s) will produce higher levels of growth than periods in which international issues are stressed (e.g., post 9/11). Combinations of these two theories create four possible trajectories of growth in women's representation that may be observed over time. We use latent growth curve models to assess the four theoretical trajectories, using data on women's state legislative representation from 1982 to 2006. We find that while women achieved fleeting success in the Year of the Woman, further gains were limited in the remainder of the 1990s and average growth stalled completely after 2001. Our results show futher that gender salience and, to a lesser extent political, climate matter to growth and change in women's political power over time.

Strength Training Prior to Endurance Exercise: Impact on the Neuromuscular System, Endurance Performance and Cardiorespiratory Responses

Conceição Matheus

2014-12-01

Full Text Available This study aimed to investigate the acute effects of two strength-training protocols on the neuromuscular and cardiorespiratory responses during endurance exercise. Thirteen young males (23.2 ± 1.6 years old participated in this study. The hypertrophic strength-training protocol was composed of 6 sets of 8 squats at 75% of maximal dynamic strength. The plyometric strength-training protocol was composed of 6 sets of 8 jumps performed with the body weight as the workload. Endurance exercise was performed on a cycle ergometer at a power corresponding to the second ventilatory threshold until exhaustion. Before and after each protocol, a maximal voluntary contraction was performed, and the rate of force development and electromyographic parameters were assessed. After the hypertrophic strengthtraining and plyometric strength-training protocol, significant decreases were observed in the maximal voluntary contraction and rate of force development, whereas no changes were observed in the electromyographic parameters. Oxygen uptake and a heart rate during endurance exercise were not significantly different among the protocols. However, the time-to-exhaustion was significantly higher during endurance exercise alone than when performed after hypertrophic strength-training or plyometric strength-training (p <0.05. These results suggest that endurance performance may be impaired when preceded by strength-training, with no oxygen uptake or heart rate changes during the exercise.

Should Body Size Categories Be More Common in Endurance Running Events?

Science.gov (United States)

Buresh, Robert

2018-05-01

Thousands of endurance running events are held each year in the United States, and most of them use age and sex categories to account for documented effects of those factors on running performance. However, most running events do not provide categories of body mass, despite abundant evidence that it, too, dramatically influences endurance running performance. The purposes of this article are to (1) discuss how body mass affects endurance running performance, (2) explain several mechanisms through which body mass influences endurance running performance, and (3) suggest possible ways in which body mass might be categorized in endurance running events.

Altered autonomic function has been identified following ultra-endurance event participation among elite world-class athletes. Despite dramatic increases in recreational athlete participation in these ultra-endurance events, the physiological effects on these athletes are less known. This investigation sought to characterise changes in surrogate measures of autonomic function: heart rate variability (HRV), blood pressure variability (BPV) and baroreceptor sensitivity (BRS) following ultra-endurance race participation. Further, we sought to compare baseline measures among ultra-endurance athletes and recreationally active controls not participating in the ultra-endurance race. Recreational ultra-endurance athletes (n = 25, 44.6 ± 8.2 years, 8 females) and recreationally active age, sex and body mass index matched controls (n = 25) were evaluated. Measurements of HRV, BPV and BRS were collected pre- and post-race for recreational ultra-endurance athletes and at baseline, for recreationally active controls. Post-race, ultra-endurance athletes demonstrated significantly greater sympathetic modulation [low frequency (LF) power HRV: 50.3 ± 21.6 normalised units (n.u.) to 65.9 ± 20.4 n.u., p = 0.01] and significantly lower parasympathetic modulation [high frequency (HF) power HRV: 45.0 ± 22.4 n.u. to 23.9 ± 13.1 n.u., p HRV and BPV measures. Recreational ultra-endurance athletes experienced increased sympathetic tone and declines in BRS post-race, similar to previously reported elite world-class ultra-endurance athletes, though still within normal population ranges.

Acquired bilateral longitudinal true leukonychia is a rare disorder. We present a case of a 35-year-old healthy woman presented with this unusual and rare manifestation. She mentioned a history of unprotected exposure to detergents and bleaching chemical agents. Considering her low zinc level, she was prescribed with zinc capsules and recommended to avoid chemical substances for 6 months. During bimonthly follow-up, her zinc level turned normal, and leukonychia subsequently disappeared. Bilateral longitudinal true leukonychia in the nails due to zinc deficiency and exposure to chemical substances has not been reported previously. Direct and indirect effects of chemical substances on matrix and the effect of zinc deficiency on healing process should be considered in these cases. PMID:27857831

2010-01-01

The effect of concurrent strength (S) and endurance (E) training on adaptive changes in aerobic capacity, endurance performance, maximal muscle strength and muscle morphology is equivocal. Some data suggest an attenuated cardiovascular and musculoskeletal response to combined E and S training......, while other data show unimpaired or even superior adaptation compared with either training regime alone. However, the effect of concurrent S and E training only rarely has been examined in top-level endurance athletes. This review describes the effect of concurrent SE training on short-term and long......-term endurance performance in endurance-trained subjects, ranging from moderately trained individuals to elite top-level athletes. It is concluded that strength training can lead to enhanced long-term (>30 min) and short-term (...

McKay, BD, Yeo, NM, Jenkins, NDM, Miramonti, AA, and Cramer, JT. Exertional rhabdomyolysis in a 21-year-old healthy woman: a case report. J Strength Cond Res 31(5): 1403-1410, 2017-The optimal resistance training program to elicit muscle hypertrophy has been recently debated and researched. Although 3 sets of 10 repetitions at 70-80% of the 1 repetition maximum (1RM) are widely recommended, recent studies have shown that low-load (∼30% 1RM) high-repetition (3 sets of 30-40 repetitions) resistance training can elicit similar muscular hypertrophy. Incidentally, this type of resistance training has gained popularity. In the process of testing this hypothesis in a research study in our laboratory, a subject was diagnosed with exertional rhabdomyolysis after completing a resistance training session that involved 3 sets to failure at 30% 1RM. Reviewed were the events leading up to and throughout the diagnosis of exertional rhabdomyolysis in a healthy recreationally-trained 21-year-old woman who was enrolled in a study that compared the acute effects of high-load low-repetition vs. low-load high-repetition resistance training. The subject completed a total of 143 repetitions of the bilateral dumbbell biceps curl exercise. Three days after exercise, she reported excessive muscle soreness and swelling and sought medical attention. She was briefly hospitalized and then discharged with instructions to take acetaminophen for soreness, drink plenty of water, rest, and monitor her creatine kinase (CK) concentrations. Changes in the subject's CK concentrations, ultrasound-determined muscle thickness, and echo intensity monitored over a 14-day period are reported. This case illustrates the potential risk of developing exertional rhabdomyolysis after a low-load high-repetition resistance training session in healthy, young, recreationally-trained women. The fact that exertional rhabdomyolysis is a possible outcome may warrant caution when prescribing this type of resistance

This study investigated the effects of endurance training only (E, n = 14) and same-session combined training, when strength training is repeatedly preceded by endurance loading (endurance and strength training (E+S), n = 13) on endurance (1000-m running time during incremental field test) and strength performance (1-repetition maximum (1RM) in dynamic leg press), basal serum hormone concentrations, and endurance loading-induced force and hormone responses in recreationally endurance-trained men. E was identical in the 2 groups and consisted of steady-state and interval running, 4-6 times per week for 24 weeks. E+S performed additional mixed-maximal and explosive-strength training (2 times per week) immediately following an incremental running session (35-45 min, 65%-85% maximal heart rate). E and E+S decreased running time at week 12 (-8% ± 5%, p = 0.001 and -7% ± 3%, p force (-5% to -9%, p = 0.032 to 0.001) and testosterone and cortisol responses (18%-47%, p = 0.013 to p benefits when strength training was performed repeatedly after endurance training compared with endurance training only. This was supported by similar acute responses in force and hormonal measures immediately post-endurance loading after the training with sustained 1RM strength in E+S.

Full Text Available Abstract Introduction Malignant peritoneal mesothelioma is a rare cancer with poor patient survival. Female gender has been identified as a positive prognostic factor. Recently, it has been suggested that the expression of estrogen receptor β in malignant mesothelioma leads to tumor suppression and a better prognosis. Case presentation We report the case of a 48-year-old Caucasian woman who is alive and disease-free seven years after the initial diagnosis and treatment of malignant peritoneal mesothelioma. Conclusion This patient's long survival may be attributable to a combination of factors, including minimal disease, complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy plus the estrogen receptor β positivity of the tumor.

1986-01-01

A 69-year-old woman was initially seen with constant abdominal pain in the epigastrium and right upper quadrant, with nausea and vomiting of three days' duration. On examination, moderate tenderness and guarding in the right upper quadrant of the abdomen were noted. A leukocytosis of 11,000/cu mm, with a mild shift to the left, was present. Findings from a sonogram and hepatobiliary scan were consistent with a diagnosis of acute cholecystitis for which intravenous (IV) antibiotic therapy was instituted. Results of radiological studies performed on the second hospital day showed a small-bowel obstruction. On surgical exploration, a gangrenous segment of the terminal ileum was resected and an end-to-end anastomosis was performed. The resected bowel demonstrated hemorrhagic infarction with evidence of focal organizing venous thrombosis in the mesentery. The patient was initially started on a regimen of IV heparin and then switched to oral coumarin. On the fourth day of coumarin therapy, massive swelling, tenderness, and erythema were noted to involve the entire right breast. Six months later, the patient was readmitted because of an acute pulmonary embolism. A residual 4x5-cm mass was present in the central portion of the right breast. The overlying skin was slightly retracted. Mammography showed an extensive masslike density behind the right nipple, with evidence of periareolar retraction. Coumarin-induced mammary necrosis was diagnosed

2011-07-01

Full Text Available Objective: Any minimal alteration in performance and coordination of scapular and glenohumeral muscles has the potential to lead to shoulder joint dysfunction. The impingement syndrome has been reported as is the most common diagnosis of shoulder pain. The purpose of this study was to determine whether endurance deficits could be detected in patients with shoulder impingement. Materials & Methods: By convenient sampling 15 patients with impingement syndrome at average of 45.3 years of age and 15 healthy persons (age 45.8 years through a case–control design participated in the study. Endurance of glenohumeral and scapulothoracic muscles were tested with a hand held dynamometer. Independent t–test was used to statistically analyze different groups. Results: Compared to non–impaired subjects, those with impingement syndrome demonstrated a significantly lower endurance of external rotation, scaption and scapular abduction and upward rotation movements (P<0.05. In impingement syndrome patients, the external–to–internal rotator muscles endurance ratio was significantly lower than the control group (P<0.05. Conclusion: The result of the study suggests that endurance deficit of rotator cuff and scapular upward rotator muscles may be an important aspect of the impingement syndrome. Shoulder girdle muscles endurance should be considered in evaluation and physical therapy of impingement syndrome patients.

Full Text Available Endurance as human capability is treated in two ways. Some authors define it as mobility capability, while others deny this theory. The denying of this theory lies in attitude that endurance is saturated with psychological factors (motivation and cardio- vascular factors as well and is often identified with aero power, typical dimension of fun- ctional diagnostics. Having that in mind this research enabled the obtaining of necessary informations which could contribute to the clearing up of these uncoordinated opinions. The research included 110 student of the III year Phisical Education in East Sarajevo, male gender. Nine (9 predictors has been applied (4 variables for mobility space estima- te, 5 variables for morphology and functional space estimate and variable used for the estimate of endurance race 1500m. Obtained results confirmed statistical significance of two functional capability variable of Harvard step test, Margarija test and mobility variable race 4x15 meters with the race results.

Legro, Richard S

2007-02-07

Ms R, a 27-year-old woman with polycystic ovary syndrome (PCOS) diagnosed after irregular menses, hirsutism, and polycystic ovaries, is concerned about weight gain despite regular exercise and watching her diet. Prescribed oral contraceptives to regulate her menses and help reduce her androgen levels, she wants to know the alternatives for treatment of PCOS. The varying definitions of PCOS and its heterogeneity confound the interpretation of studies on PCOS. Specific diagnostic criteria have been established based on expert opinion but have not been validated. Several commonly performed laboratory tests are generally unhelpful and the pathophysiology is poorly understood. Treatment options for Ms R, including those that may affect her weight gain, are reviewed and implications for future fertility are discussed.

Stent graft evolution is often addressed as a cause for improved outcomes of endovascular aneurysm repair for patients with an abdominal aortic aneurysm. In this study, we directly compared the midterm result of Endurant stent graft with its predecessor, the Talent stent graft (both Medtronic, Santa Rosa, Calif). Patient treated from January 2005 to December 2010 in a single tertiary center in The Netherlands with a Talent or Endurant stent graft were eligible for inclusion. Ruptured abdominal aortic aneurysms or patients with previous aortic surgery were excluded. The primary end point was the Kaplan-Meier estimated freedom from secondary interventions. Secondary end points were perioperative outcomes and indications for secondary interventions. In total, 221 patients were included (131 Endurant and 90 Talent). At baseline, the median aortic bifurcation was narrower for the Endurant (30 mm vs 39 mm; P Talent and Endurant, respectively. The estimated freedom from secondary interventions at 30 days, 1 year, 5 years, and 7 years was 94.3%, 89.4%, 72.2%, and 64.1% for Talent and 96.8%, 89.3%, 75.2%, and 69.2% for Endurant (P = .528). The indication for secondary interventions does differ; more patients required an intervention for a proximal neck-related complication (type Ia endoleak or migration) in the Talent group (18.2% vs 4.8%; P = .001), whereas more interventions for iliac limb stenosis were seen in the Endurant group (0.0% vs 4.8%; P = .044). In a binomial regression analysis, suprarenal angulation, infrarenal neck length, and type of stent graft were independent predictors of neck-related complications. Evolution from the Talent stent graft into the Endurant has resulted in significant reduction of infrarenal neck-related complications; on the other hand, iliac interventions increased. The overall midterm secondary intervention rate was comparable. Copyright © 2017 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

Autonomous Soaring for Improved Endurance of a Small Uninhabited Air Vehicle

Science.gov (United States)

Allen, Michael J.

2005-01-01

A relatively unexplored method to improve the endurance of an autonomous aircraft is to use buoyant plumes of air found in the lower atmosphere called thermals or updrafts. Glider pilots and birds commonly use updrafts to improve range, endurance, or cross-country speed. This report presents a quantitative analysis of a small electric-powered uninhabited air vehicle using updrafts to extend its endurance over a target location. A three-degree-of-freedom simulation of the uninhabited air vehicle was used to determine the yearly effect of updrafts on performance. Surface radiation and rawinsonde balloon measurements taken at Desert Rock, Nevada, were used to determine updraft size, strength, spacing, shape, and maximum height for the simulation. A fixed-width spiral path was used to search for updrafts at the same time as maintaining line-of-sight to the surface target position. Power was used only when the aircraft was flying at the lower-altitude limit in search of updrafts. Results show that an uninhabited air vehicle with a nominal endurance of 2 hours can fly a maximum of 14 hours using updrafts during the summer and a maximum of 8 hours during the winter. The performance benefit and the chance of finding updrafts both depend on what time of day the uninhabited air vehicle is launched. Good endurance and probability of finding updrafts during the year was obtained when the uninhabited air vehicle was launched 30 percent into the daylight hours after sunrise each day. Yearly average endurance was found to be 8.6 hours with these launch times.

Torsion of normal adnexa in a 31-year-old woman: A case report and literature review

Full Text Available It is known that a large ovarian cyst will likely cause torsion. However, normal adnexal torsion is rare and occurs in premenarchal girls in most cases. This is a case of a reproductive woman. A 31-year-old woman suffering from acute abdominal pain in the lower and right side consulted her gynecologist. The next day she had a computed tomography performed and was suspected of ovarian torsion. She did not have fever, nausea, or leukocytosis, but her abdominal pain persisted. Diagnostic laparoscopy was performed and showed torsion of the right fallopian tube, which was swollen and looked like a hydrosalpinx with a normal ovary. We did detorsion and excision of the right tube. However, pathological findings showed that the right tube was not a hydrosalpinx but was swollen due to blood stasis. We determined that this case was torsion of normal adnexa. In such cases, diagnostic laparoscopy is very effective.

The aim of this study was to investigate whether nocturnal heart rate variability (HRV) can be used to predict changes in endurance performance during 28 weeks of endurance training. The training was divided into 14 weeks of basic training (BTP) and 14 weeks of intensive training periods (ITP). Endurance performance characteristics, nocturnal HRV, and serum hormone concentrations were measured before and after both training periods in 28 recreational endurance runners. During the study peak treadmill running speed (Vpeak ) improved by 7.5 ± 4.5%. No changes were observed in HRV indices after BTP, but after ITP, these indices increased significantly (HFP: 1.9%, P=0.026; TP: 1.7%, P=0.007). Significant correlations were observed between the change of Vpeak and HRV indices (TP: r=0.75, PHRV among recreational endurance runners, it seems that moderate- and high-intensity training are needed. This study showed that recreational endurance runners with a high HRV at baseline improved their endurance running performance after ITP more than runners with low baseline HRV. © 2011 John Wiley & Sons A/S.

Christou, Demetra D; Jones, Pamela Parker; Seals, Douglas R

2003-06-01

Baroreflex buffering plays an important role in arterial blood pressure control. Previous reports suggest that baroreflex sensitivity may be altered in endurance exercise-trained compared with untrained subjects. It is unknown, however, if in vivo baroreflex buffering is altered in the endurance exercise-trained state in humans. Baroreflex buffering was determined in 36 healthy normotensive men (18 endurance exercise-trained, 41+/-5 [SEM] years; 18 untrained, 41+/-4 years) by measuring the potentiation of the systolic blood pressure responses to a phenylephrine bolus and to incremental phenylephrine infusion during compared with before ganglionic blockade with trimethaphan. The exercise-trained men had a lower resting heart rate and higher maximal oxygen consumption and heart rate variability than the sedentary control subjects (all P=0.01). Mean levels and variability of blood pressure, cardiovagal baroreflex sensitivity (change in heart rate/change in systolic blood pressure), and basal muscle sympathetic nerve activity were not different in the two groups. The systolic blood pressure responses to phenylephrine were not different in the endurance-trained and untrained men before or during ganglionic blockade (P>0.6). Measures of baroreflex buffering with the use of a phenylephrine bolus (3.9+/-0.8 versus 4.0+/-0.7, trained versus untrained, P=0.85) and incremental infusion (2.8+/-0.4 versus 2.5+/-0.6, P=0.67) were similar in the two groups. Baroreflex buffering does not differ in endurance exercise-trained compared with untrained healthy men. These results support the concept that habitual vigorous endurance exercise does not modulate in vivo baroreflex buffering in healthy humans.

Polycystic ovary syndrome (PCOS) and Graves' disease are the common causes of menstrual irregularity leading to infertility in women of child-bearing age. A 21-year-old female patient visited us with complaints of oligomenorrhea and hand tremor. She was diagnosed as having PCOS and hyperthyroid Graves' disease, simultaneously. She had low body weight (BMI: 16.4 kg/m(2)), mild hirsutism, and thyrotoxicosis. The patient was treated with anti-thyroid drug and beta-blocker for about two years, and then recovered to normal thyroid function. Although some studies have suggested a connection between PCOS and autoimmune thyroiditis, no study indicated that PCOS is associated with Graves' disease until now. Here, we describe the first case report of a lean woman with normal insulin sensitivity presenting PCOS and Graves' disease simultaneously.

Carbohydrate mouth rinse: does it improve endurance exercise performance?

Directory of Open Access Journals (Sweden)

Painelli Vitor

2010-08-01

Full Text Available Abstract It is well known that carbohydrate (CHO supplementation can improve performance in endurance exercises through several mechanisms such as maintenance of glycemia and sparing endogenous glycogen as well as the possibility of a central nervous-system action. Some studies have emerged in recent years in order to test the hypothesis of ergogenic action via central nervous system. Recent studies have demonstrated that CHO mouth rinse can lead to improved performance of cyclists, and this may be associated with the activation of brain areas linked to motivation and reward. These findings have already been replicated in other endurance modalities, such as running. This alternative seems to be an attractive nutritional tool to improve endurance exercise performance.

Recovery time between each sequence is 10 seconds throughout the test, but the time to complete each sequence is gradually decreased until the subjects cannot follow the dictated tempo. The B-ENDURANCE test performance for elite players was better (p ≤ 0.05) compared with the skilled players and nonbadminton players. In addition, the B-ENDURANCE test performance correlated (r = 0.8 and p badminton-specific endurance but at least 1 familiarization trial is recommended if the test is used for evaluation of longitudinal changes, e.g., tracking training effects.

Detection of Mercury in Human Organs and Hair in a Case of a Homicidal Poisoning of a Woman Autopsied 6 Years After Death.

Lech, Teresa

2015-09-01

In the described case of the death of a 53-year-old woman, no toxicological examination was performed directly after death (only an anatomopathological autopsy), although symptoms of serious gastrointestinal disturbances had been present (the woman had been hospitalized twice in the course of several months). It was assumed that the cause of death was myocardial infarction. Five years later, some new circumstances came to light which suggested that somebody could have administered some poison (metals, cyanides) to the woman. Toxicological analysis of postmortem samples from the corpse, exhumed 6 years after death by order of the public prosecutor's office, revealed high tissue mercury contents in biological material (cold vapor atomic absorption spectrometry): small intestine, 1516 ng/g; large intestine, 487 ng/g; liver, 1201 ng/g; heart muscle, 1023 ng/g; and scalp hair, 227 ng/g. In samples of soil from places near the coffin, negligible traces of mercury were found (0.5-1.5 ng/g); contamination by mercury from the environment was ruled out. The presented case is a rare example of recognition of mercury poisoning on the basis of the results of analysis of biological material from an exhumed cadaver.

Pigmented Paget disease of the nipple is a rare disease. We report on a 60-year-old woman in whom this diagnosis was made based on clinical findings, dermoscopy, histology and immunohistology. Circumscribed pigmentation of the nipple includes a wide spectrum of benign and malignant differential diagnostic considerations. Dermoscopy can enhance the clinical diagnosis. Biopsies should always be performed on unclear pigmentation of the nipple in both women and men. On histology, rare melanocytic tumors must be differentiated from pigmented Paget disease and pigmented Bowen disease. Pagetoid intraepithelial cells of a melanocytic tumor are positive for S100, HMB45 or melan A, but not for cytokeratins. Intraepithelial tumor cells of Paget disease are positive for cytokeratin 7. The clear cells in Bowen diseases are usually not positive for cytokeratin 7 and are also negative for all melanocytic markers.

'Stalkitis' in a pregnant 32-year-old woman: A rare cause of diabetes insipidus

1999-01-01

A case of lymphocytic infundibulo-neurohypophysitis (LINH) or 'stalkitis' in a 32-year-old woman who presented with diabetes insipidus (DI) during pregnancy is reported here. The diagnosis was made with MR imaging. The clinical and radiological features of this rare disorder and the differential diagnosis of infundibular mass lesions are discussed. The differentiation from lymphocytic adenohypophysitis (LAH) is made. No improvement of the DI accompanying LINH is achieved with trans-sphenoidal surgery. Hence, recognition of typical cases with MR imaging and appropriate medical management avoids unnecessary neurosurgery. This is the second reported case of LINH during pregnancy and may suggest an association. Copyright (1999) Blackwell Science Pty Ltd

Cor triatriatum dexter is a rare congenital heart anomaly in which a membrane divides the right atrium into 2 chambers. We report the case of a 43-year-old woman who had cor triatriatum dexter and a large atrial septal defect. During attempted percutaneous closure, the balloon disrupted the membrane and revealed that the defect had no inferior rim, precluding secure placement of an Amplatzer Septal Occluder. Surgical treatment subsequently proved to be successful. In patients with an incomplete membrane and a septal defect with well-defined rims, percutaneous treatment can be the first choice. In patients who have cor triatriatum dexter and unfavorable anatomic features or concomitant complex heart anomalies, open-heart surgery remains the gold standard for treatment.

Does Effectiveness of Adolescent Smoking-Cessation Intervention Endure Into Young Adulthood? 7-Year Follow-Up Results from a Group-Randomized Trial.

Arthur V Peterson

Full Text Available The Hutchinson Study of High School Smoking was the first randomized trial to show effectiveness of a smoking cessation intervention on 6-months prolonged smoking abstinence at one year post-intervention in a large population-based sample of adolescent smokers. An important question remains: Do the positive effects from teen smoking cessation interventions seen at up to 12 months post-intervention endure into young adulthood?

The Hutchinson Study of High School Smoking was the first randomized trial to show effectiveness of a smoking cessation intervention on 6-months prolonged smoking abstinence at one year post-intervention in a large population-based sample of adolescent smokers. An important question remains: Do the positive effects from teen smoking cessation interventions seen at up to 12 months post-intervention endure into young adulthood? This study examines for the first time whether such positive early effects from teen smoking cessation intervention can endure into young adulthood in the absence of additional intervention. High school smokers (n = 2,151) were proactively recruited into the trial from fifty randomly selected Washington State high schools randomized to the experimental (Motivational Interviewing + Cognitive Behavioral Skills Training telephone counseling intervention) or control (no intervention) condition. These smokers were followed to 7 years post high school to ascertain rates of six-year prolonged smoking abstinence in young adulthood. All statistical tests are two-sided. No evidence of intervention impact at seven years post high school was observed for the main endpoint of six-year prolonged abstinence, neither among all smokers (14.2% in the experimental condition vs. 13.1% in the control condition, difference = +1.1%, 95% confidence interval (CI) = -3.4 to 5.8, p = .61), nor among the subgroups of daily smokers and less-than-daily smokers, nor among other a priori subgroups. But, observed among males was some evidence of an intervention impact on two endpoints related to progress towards quitting: reduction in number of days smoked in the past month, and increase in the length of the longest quit attempt in the past year.

Master athletes are extending the limits of human endurance

Full Text Available The increased participation of master athletes (i.e. > 40 years old in endurance and ultra-endurance events (> 6h duration over the past few decades has been accompanied by an improvement in their performances at a much faster rate than their younger counterparts. Ageing does however result in a decrease in overall endurance performance. Such age-related declines in performance depend upon the modes of locomotion, event duration and gender of the participant. For example, smaller age-related declines in cycling performance than in running and swimming have been documented. The relative stability of gender differences observed across the ages suggests that the age-related declines in physiological function did not differ between males and females. Among the main physiological determinants of endurance performance, the maximal oxygen consumption (VO2max appears to be the parameter that is most altered by age. Exercise economy and the exercise intensity at which a high fraction of VO2max can be sustained (i.e. lactate threshold, seem to decline to a lesser extent with advancing age. The ability to maintain a high exercise-training stimulus with advancing age is emerging as the single most important means of limiting the rate of decline in endurance performance. By constantly extending the limits of (ultra-endurance, master athletes therefore represent an important insight into the ability of humans to maintain physical performance and physiological function with advancing age.

Training modalities: impact on endurance capacity.

Science.gov (United States)

Flueck, Martin; Eilers, Wouter

2010-03-01

Endurance athletes demonstrate an exceptional resistance to fatigue when exercising at high intensity. Much research has been devoted to the contribution of aerobic capacity for the economy of endurance performance. Important aspects of the fine-tuning of metabolic processes and power output in the endurance athlete have been overlooked. This review addresses how training paradigms exploit bioenergetic pathways in recruited muscle groups to promote the endurance phenotype. A special focus is laid on the genome-mediated mechanisms that underlie the conditioning of fatigue resistance and aerobic performance by training macrocycles and complements. The available data on work-induced muscle plasticity implies that different biologic strategies are exploited in athletic and untrained populations to boost endurance capacity. Olympic champions are probably endowed with a unique constitution that renders the conditioning of endurance capacity for competition particularly efficient. Copyright 2010 Elsevier Inc.

Full Text Available Idiopathic scoliosis (IS is the most common type of scoliosis. Clinical signs and symptoms of scoliosis impair quality of life and daily function. Manual therapy is commonly used for treatment of scoliosis. This is a case report of scoliosis treatment with manual therapy in a 28 years old patient. A 28 years old woman complained of low back pain for 4 years. Spine x-ray, showed scoliosis with a 32 degrees Cobb angle. The patient received a manual therapy procedure of two visits per week for 16 weeks including myofascial release technique, mobilization and manipulation. The Cobb angle was reduced 15.62% after 8 weeks and 21.87% after 16 weeks. In addition the pain was reduced by 50%. We can state that manual therapy was useful for this patient.

Mental toughness in endurance athletes, while an important factor for success, has been scarcely studied. An online survey was used to examine eight mental toughness factors in endurance athletes. The study aim was to determine mental toughness profiles via latent profile analysis in endurance athletes and whether associations exist between the latent profiles and demographics and sports characteristics. Endurance athletes >18 years of age were recruited via social media outlets (n = 1245, 53% female). Mental toughness was measured using the Sports Mental Toughness Questionnaire (SMTQ), Psychological Performance Inventory-Alternative (PPI-A), and self-esteem was measured using the Rosenberg Self-Esteem Scale (RSE). A three-class solution emerged, designated as high mental toughness (High MT), moderate mental toughness (Moderate MT) and low mental toughness (Low MT). ANOVA tests showed significant differences between all three classes on all 8 factors derived from the SMTQ, PPI-A and the RSE. There was an increased odds of being in the High MT class compared to the Low MT class for males (OR = 1.99; 95% CI, 1.39, 2.83; Pathletes who were over 55 compared to those who were 18-34 (OR = 2.52; 95% CI, 1.37, 4.62; Pathletes. High MT is associated with demographics and sports characteristics. Mental toughness screening in athletes may help direct practitioners with mental skills training.

2013-04-23

Growth from conception to reproductive onset in African elephants (Loxodonta africana) provides insights into phenotypic plasticity, individual adaptive plastic responses and facultative maternal investment. Using growth for 867 and life histories for 2652 elephants over 40 years, we demonstrate that maternal inexperience plus drought in early life result in reduced growth rates for sons and higher mortality for both sexes. Slow growth during early lactation was associated with smaller adult size, later age at first reproduction, reduced lifetime survival and consequently limited reproductive output. These enduring effects of trading slow early growth against immediate survival were apparent over the very long term; delayed downstream consequences were unexpected for a species with a maximum longevity of 70+ years and unpredictable environmental experiences.

Urethral duplication is a rare finding in females, with fewer than 40 cases published since 1970. We report a case of urethral duplication in a woman with uterovaginal and rectal prolapse but without other associated congenital anomalies. On urodynamic and cystoscopic evaluation, an accessory urethra was noted to emerge from beneath the clitoral hood. The patient underwent exploratory laparotomy and transabdominal excision of the rudimentary urethral orifice with concurrent transvaginal prolapse repair and rectopexy. At 5-year follow-up, the patient continued to be continent and without prolapse.

We report a case of problematic spontaneous orgasms during sleep in a 57-year-old woman who also complained of hypnic jerks and symptoms of exploding head syndrome. To our knowledge, this is the first case report in the English language literature of problematic spontaneous orgasms during sleep. She had a complex medical and psychiatric history, and was taking oxycontin, venlafaxine, amitriptyline, and lurasidone. Prolonged video electroencephalogram monitoring did not record any ictal or interictal electroencephalogram discharges, and nocturnal video polysomnography monitoring did not record any behavioral or orgasmic event. Periodic limb movement index was zero events/h. Severe central sleep apnea was detected with apnea-hypopnea index = 130 events/h, but she could not tolerate positive airway pressure titration. Sleep architecture was disturbed, with 96.4% of sleep spent in stage N2 sleep. Bedtime clonazepam therapy (1.5 mg) was effective in suppressing the sleep-related orgasms and hypnic jerks. © 2018 American Academy of Sleep Medicine

Elite endurance athletes are characterized by markedly increased hemoglobin mass (Hbmass). It has been hypothesized that this adaptation may occur as a response to training at a very young age. Therefore, the aim of this study was to monitor changes in Hbmass in children aged 8-14 years following systematic endurance training. In the first study, Hbmass, VO2max, and lean body mass (LBM) were measured in 17 endurance-trained children (13 boys and 4 girls; aged 9.7 ± 1.3 years; training history 1.5±1.8 years; training volume 3.5 ± 1.6 h) twice a year for up to 3.5 years. The same parameters were measured once in a control group of 18 age-matched untrained children. Hbmass and blood volume (BV) were measured using the optimized CO-rebreathing technique, VO2max by an incremental test on a treadmill, and LBM by skin-fold measurements. In the second pilot study, the same parameters were measured in 9 young soccer athletes (aged 7.8 ± 0.2 years), and results were assessed in relation to soccer performance 2.5 years later. The increase in mean Hbmass during the period of study was 50% which was closely related to changes in LBM ( r = 0.959). A significant impact of endurance training on Hbmass was observed in athletes exercising more than 4 h/week [+25.4 g compared to the group with low training volume (LBM (11.4 g·kg -1 LBM) and overlapped with the effects of age. A strong relationship was present between absolute Hbmass and VO2max ( r = 0.939), showing that an increase of 1 g hemoglobin increases VO2max by 3.6 ml·min -1 . Study 2 showed a positive correlation between Hbmass and soccer performance 2.5 years later at age 10.3 ± 0.3 years ( r = 0.627, p = 0.035). In conclusion, children with a weekly training volume of more than 4 h show a 7% higher Hbmass than untrained children. Although this training effect is significant and independent of changes in LBM, the major factor driving the increase in Hbmass is still LBM.

Sofia Ionescu, the first woman neurosurgeon in the world.

The authors present the activity of Mrs. Sofia Ionescu, the one female surgeon who was nominated as the first woman neurosurgeon in the world. Sofia Ionescu worked in the field of neurosurgery for 47 years, performing all the known neurosurgical procedures of the time. She made herself known through her incredible surgical skill and her enormous work power. Due to her incredible modesty and workload, she never participated at international congresses or manifestations. The nomination as first woman neurosurgery took place in Marrakech, Morocco, during the 2005 WFNS Congress. Although some claim that Diana Beck was the first woman neurosurgeon in the world, our theory suggests otherwise. The first documented surgical intervention performed by Diana Beck dates to 1952. Sofia Ionescu operated for the first time on a human brain as early as 1944. Furthermore, Diana Beck's actions surfaced in the year 1947, long after the war had ended and Sofia Ionescu had become a neurosurgeon. Copyright © 2013. Published by Elsevier Inc.

Staphylococcus lugdunensis is a coagulase-negative staphylococcus (CNS). It is a major cause of prosthetic valve endocarditis; mitral valve prolapse (MVP) has emerged as a prominent predisposing structural cardiac abnormality. We describe a case of Staphylococcus lugdunensis endocarditis in an 18-year-old woman with preexisting mitral valve prolapse complaining of fever, a one-month history of continuous-remittent fever (T max 38.6°C). The transthoracic echocardiogram revealed large vegetation on the anterior mitral valve leaflet flopping from the atrial side to the ventricular side. Five sets of blood cultures were positive for coagulase-negative staphylococci. During hospitalization, after two weeks of antibiotic therapy, the patient complained of sudden pain in her right leg associated with numbness. Lower limb arterial Doppler ultrasound showed an arterial thrombosis of right common iliac artery. Transfemoral iliac embolectomy was promptly performed and on septic embolus S. lugdunensis with the same antibiotic sensitivity and the same MIC values was again isolated. Our patient underwent cardiac surgery: triangular resection of the A2 with removal of infected tissue including vegetation. Our case is an example of infective endocarditis by S. lugdunensis on native mitral valve in a young woman of 18 with anamnesis valve prolapse. PMID:23424690

2017-06-05

Slightly elevated serum human chorionic gonadotropin (hCG) can be a normal finding in postmenopausal women. We report a case of a 59-year-old woman with a history of abnormal uterine bleeding who presented with a concern for pregnancy after developing nausea and vomiting a few weeks after unprotected intercourse. Although pregnancy was extremely unlikely, hCG was obtained in order to reassure the patient since she reported that her mother conceived at the age of 60. Serum hCG was positive, prompting concern for malignancy versus pregnancy. Stable serum hCG levels, elevated follicle-stimulating hormone and negative transvaginal ultrasound ruled out both malignancy and pregnancy. Positive serum pregnancy test and hCG elevation was attributed to normal postmenopausal state. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Full Text Available Objective. To examine the effects of a 12-week Hatha yoga intervention on cardiorespiratory endurance, muscular strength and endurance, and flexibility in Chinese adults. Methods. 173 adults (aged 52.0 ± 7.5 years were assigned to either the yoga intervention group (n=87 or the waitlist control group (n=86. 19 dropped out from the study. Primary outcomes were changes in cardiorespiratory endurance (resting heart rate (HR and maximal oxygen uptake (VO2max, muscular strength and endurance (curl-up and push-up tests, and lower back and hamstring flexibility (the modified back-saver sit-and-reach (MBS test. Results. Compared to controls, the yoga group achieved significant improvements in VO2max (P<0.01, curl-up (P<0.05 and push-up (P<0.001 tests, and the MBS left and right leg tests (both P<0.001 in both genders. Significant change was also found for resting HR between groups in women (P<0.05 but not in men. Further analysis comparing participants between younger and older subgroups yielded similar findings, except that the older participants in the yoga group failed to improve resting HR or the curl-up test versus control. Adherence (89% and attendance (94% were high. No serious adverse events occurred. Conclusion. A 12-week Hatha yoga intervention has favorable effects on cardiorespiratory endurance, muscular strength and endurance, and flexibility in Chinese adults.

Endothelial function is reduced by age, chronic heart failure, coronary artery disease, hypertension or type 2 diabetes, and it is shown that aerobic exercise may reverse this trend. The effect of a high aerobic training status on endothelial function in young, healthy subjects is however less clear. The present study was designed to determine whether endothelial function is improved in highly endurance-trained young women compared to sedentary, healthy controls. Brachial artery diameter was measured in 16 endurance-trained (age: 23.7 +/- 2.5 years, maximal oxygen uptake (VO2max): 60.6 +/- 4.5 ml/kg per min) and 14 sedentary females (age: 23.7 +/- 2.1 years, VO2max: 40.5 +/- 5.6 ml/kg per min) at rest, during flow-mediated dilation (FMD) and after sublingual glycerol trinitrate administration, using high-resolution ultrasound. FMD did not differ between the endurance-trained and the sedentary females (14.8% vs 16.4%, p = NS), despite a substantial difference in VO2max of 50% (p endurance-trained group possessed however, a 9% larger resting brachial artery diameter when adjusted for body surface area. The results of the present study suggest that endothelial function is well preserved in young, healthy women, and that a high aerobic training status due to long term aerobic training does not improve the dilating capacity any further.

Endurance running performance in athletes with asthma.

Freeman, W; Williams, C; Nute, M G

1990-01-01

Laboratory assessment was made during maximal and submaximal exercise on 16 endurance trained male runners with asthma (aged 35 +/- 9 years) (mean +/- S.D.). Eleven of these asthmatic athletes had recent performance times over a half-marathon, which were examined in light of the results from the laboratory tests. The maximum oxygen uptake (VO2max) of the group was 61.8 +/- 6.3 ml kg-1 min-1 and the maximum ventilation (VEmax) was 138.7 +/- 24.7 l min-1. These maximum cardio-respiratory responses to exercise were positively correlated to the degree of airflow obstruction, defined as the forced expiratory volume in 1 s (expressed as a percentage of predicted normal). The half-marathon performance times of 11 of the athletes ranged from those of recreational to elite runners (82.4 +/- 8.8 min, range 69-94). Race pace was correlated with VO2max (r = 0.863, P less than 0.01) but the highest correlation was with the running velocity at a blood lactate concentration of 2 mmol l-1 (r = 0.971, P less than 0.01). The asthmatic athletes utilized 82 +/- 4% VO2max during the half-marathon, which was correlated with the %VO2max at 2 mmol l-1 blood lactate (r = 0.817, P less than 0.01). The results of this study suggest that athletes with mild to moderate asthma can possess high VO2max values and can develop a high degree of endurance fitness, as defined by their ability to sustain a high percentage of VO2max over an endurance race. In athletes with more severe airflow obstruction, the maximum ventilation rate may be reduced and so VO2max may be impaired. The athletes in the present study have adapted to this limitation by being able to sustain a higher %VO2max before the accumulation of blood lactate, which is an advantage during an endurance race. Therefore, with appropriate training and medication, asthmatics can successfully participate in endurance running at a competitive level.

Full Text Available The purpose of this study was to analyse the effects of order and sequence of concurrent resistance and endurance training on body fat percentage (BFP in a large sample of elementary school-aged girls. One hundred and twenty-six healthy girls, aged 10-11 years (10.95 ± 0.48 years, were randomly assigned to six groups to perform different training protocols per week for 8 weeks: Resistance-only (R, Endurance-only (E, Concurrent Distinct Endurance-Resistance (CDER, Concurrent Parallel Endurance-Resistance (CPER, Concurrent Parallel Resistance-Endurance (CPRE, and a Control group (C. In R and E, the subjects performed single sessions of resistance or endurance exercises, respectively (two days per week. In CDER, resistance-endurance training was performed on different days each week (four days per week. CPER and CPRE performed single-session combined endurance-resistance training or combined resistance-endurance training, respectively, each week (two days per week. After an 8-week training period, BFP decreased in all experimental groups (CPER: 13.3%, p0.05; and CDER: 5.6%, p>0.05. However, a significant difference was found in CPER and CPRE when compared to CDER, E, and R, indicating that training sequence may influence BFP. All programmes were effective, but CPER and CPRE obtained better results for BFP than CDER, E, or R. The effects of concurrent resistance and endurance training on body fat percentage can be mediated by order and sequence of exercise. These results provide insight into optimization of school-based fat loss exercise programmes in childhood.

Full Text Available The hypopigmented variant of mycosis fungoides (MF is charactrized by the presence of hypopigmented patches as the sole manifestation of the disease. This variant is usually observed in the dark skin of African or Asian individuals particularly children, but nevertheless is an uncommonly reported presentation of the disease. The incidence of hypopigmented MF in Caucasian patients and others of fair skin color is rare. We describe hypopigmented lesions arising in a twenty-year-old Saudi woman with type IV skin color. The diagnosis of mycosis fungoides stage IA was made based on the clinico-radiological and histological features. The patient responded well to PUVA therapy and is currently clear of lesions. MF should be considered in the differential diagnosis of hypopigmented macular lesions in patients of any skin color and age. Multiple skin biopsies must be performed on different occasions so as not to miss the diagnosis; and long term follow up is recommended since recurrence is common and occasional cases behave aggressively.

Treatment of type 1 diabetes mellitus (DM) aims to prevent complications by strictly optimizing blood glucose levels. Although physical exercise is an important part of metabolic control, endurance sports are considered hazardous for patients with type 1 diabetes because of the extreme physiological stress they represent. To further elucidate the metabolic challenge this form of exercise presented we investigated the performance of triathlon competitors with type 1 diabetes. Ten patients (32-61 years) with type 1 diabetes (disease duration 2-35 years) were followed for three years, during which each year they participated in one triathlon long-distance competitions (2.4 miles swimming, 26.2 miles running and 112 miles cycling; Ironman Germany 2005-2007). Glucose, cortisol, aldosterone, renin, thyroid hormones, testosterone, growth hormone and catecholamines were measured in blood and saliva. Five non-diabetic competitors served as controls. The performance equalled those of age-matched healthy athletes. Several participants experienced hyperglycemia early in the bike leg, whereas all of them developed low blood glucose levels during the marathon leg. Basal insulin supply was reduced up to 50 % on race day. Hormone levels in athletes with type 1 DM and healthy controls were similar. Patients with type 1 DM can successfully sustain extreme endurance challenges. Physiological alterations of the metabolic state complicated by type 1 DM can readily be compensated by adapting intensified insulin therapy and nutritional modifications. Thus 1 DM should not be regarded a contraindication to participating in high endurance sports.

Supervised periodized mixed maximal and explosive strength training added to endurance training in recreational endurance runners was examined during an 8-week intervention preceded by an 8-week preparatory strength training period. Thirty-four subjects (21-45 years) were divided into experimental groups: men (M, n = 9), women (W, n = 9), and control groups: men (MC, n = 7), women (WC, n = 9). The experimental groups performed mixed maximal and explosive exercises, whereas control subjects performed circuit training with body weight. Endurance training included running at an intensity below lactate threshold. Strength, power, endurance performance characteristics, and hormones were monitored throughout the study. Significance was set at p ≤ 0.05. Increases were observed in both experimental groups that were more systematic than in the control groups in explosive strength (12 and 13% in men and women, respectively), muscle activation, maximal strength (6 and 13%), and peak running speed (14.9 ± 1.2 to 15.6 ± 1.2 and 12.9 ± 0.9 to 13.5 ± 0.8 km Ł h). The control groups showed significant improvements in maximal and explosive strength, but Speak increased only in MC. Submaximal running characteristics (blood lactate and heart rate) improved in all groups. Serum hormones fluctuated significantly in men (testosterone) and in women (thyroid stimulating hormone) but returned to baseline by the end of the study. Mixed strength training combined with endurance training may be more effective than circuit training in recreational endurance runners to benefit overall fitness that may be important for other adaptive processes and larger training loads associated with, e.g., marathon training.

A 70-year-old woman noticed difficulty in speech and weakness of the left upper and lower limb upon awakening. Neurological examination showed dysarthria and left hemiparesis. No sensory disturbance was observed. Brain MRI revealed acute infarction in the right posterior limb of the internal capsule. On the hospital day 1, she developed the abnormal sensations restricted to the bilateral shoulders, resulting in difficulty initiating sleep. On laboratory data, renal function and serum hemoglobin and ferritin levels were normal. When four essential features of restless legs syndrome (RLS) were applied to her shoulders, the patient met RLS criteria. Following low dose pramipexole treatment, the abnormal sensation of the shoulders and insomnia significantly improved. We should be aware of the possibility of RLS or its variant, including "restless shoulder" of our patient, for the cause of insomnia following acute ischemic infarction.

Background: Since it has been shown that spending 18 h under dim light conditions can result in reduced handgrip endurance, it was questioned whether or not a shorter exposure to dim light (i.e., 1 h) would have similar influence upon muscular endurance. Therefore this study compared the number of weighted knee extension lifts that could be done after spending 1 h in either dim or bright light. Methods: Participants (5 women, 11 men, college students 19–26 years) performed knee extension l...

Aims To compare the effects of endurance training with endurance strength training on the anthropometric, body composition, physical capacity, and circulatory parameters in obese women. Methods 44 women with abdominal obesity were randomized into groups A and B, and asked to perform endurance (A) and endurance strength training (B) for 3 months, 3 times/week, for 60 min. Dual-energy X-ray absorptiometry and Graded Exercise Test were performed before and after training. Results Significant decreases in body mass, BMI, total body fat, total body fat mass, and waist and hip circumference were observed after both types of intervention. Marked increases in total body lean and total body fat-free mass were documented in group B. In both groups, significant increases in peak oxygen uptake, time to exhaustion, maximal work rate, and work rate at ventilatory threshold were accompanied by noticeably decreased resting heart rate, resting systolic blood pressure, and resting and exercise diastolic blood pressure. No significant differences were noticed between groups for the investigated parameters. Conclusion Our findings demonstrate evidence for a favorable and comparable effect of 3-month endurance and endurance strength training on anthropometric parameters, body composition, physical capacity, and circulatory system function in women with abdominal obesity.

1995-10-23

A case of Parvovirus B19 infection (erythema infectiosum) in a 20 year old woman is presented. The patient presented with fever, arthritis in one knee, neutrophil granulocytosis and biochemical evidence of hepatitis. Serological evidence of Parvovirus B19 infection was found as the only explanation of the clinical picture. Hepatitis was due to Parvovirus B19 infection as there was no serological evidence of EBV or CMV reactivation. Neutrophil granulocytosis and thrombocytosis were found and were probably due to an active bone marrow in the recovery phase of bone marrow aplasia.

Nutritional Supplements for Endurance Athletes

Science.gov (United States)

Rasmussen, Christopher J.

Athletes engaged in heavy endurance training often seek additional nutritional strategies to help maximize performance. Specific nutritional supplements exist to combat certain factors that limit performance beginning with a sound everyday diet. Research has further demonstrated that safe, effective, legal supplements are in fact available for today's endurance athletes. Several of these supplements are marketed not only to aid performance but also to combat the immunosuppressive effects of intense endurance training. It is imperative for each athlete to research the legality of certain supplements for their specific sport or event. Once the legality has been established, it is often up to each individual athlete to decipher the ethics involved with ingesting nutritional supplements with the sole intent of improving performance.

The status of a breastfeeding woman in labour law

Directory of Open Access Journals (Sweden)

Rabovanović Dragana

2016-01-01

Full Text Available The legal status of an employed woman who is breastfeeding is regulated by the special Occupational Safety and Health Act. This Act implies a number of specific measures developed to ensure that breastfeeding women and their children, as a particularly vulnerable group, are provided with a fuller support and protection. Thus, a breastfeeding woman is guaranteed the right to take one or more daily breaks to breastfeed her child, or the right to work shorter working hours on the daily basis, provided that she returns to work within a period of one year from the birth of her child. Moreover, a breastfeeding woman shall not be obliged to perform work which has been assessed as significantly risky to her health or to the health of her child. However, a complete occupational safety and health protection of a breastfeeding woman also implies protection from discrimination on the grounds of family responsibilities, as well as creating work environment where every employee can effectively exercise the right to fair working conditions, taking into consideration the risk of discrimination that the breastfeeding woman is exposed to and the difficulties she faces while exercising certain employment rights. This paper analyses the status of employed breastfeeding women in labour legislation in order to discuss and underscore the legal protection goals and to indicate the risks which endanger their dignity and wellbeing.

The aim of this study was to examine the sit up test to exhaustion as a field test for muscular endurance evaluation in a sample of sedentary people of both sexes. A cross-sectional study was performed. Three-hundred-eighty-one participants volunteered for the study (28.5 ± 10.0 years; 168.2 ± 8.9 cm; 65.1 ± 11.1 kg), of which 194 males (27.5 ± 10.2 years; 173.6 ± 7.0 cm; 71.2 ± 5.2 kg) and 187 females (29.6 ± 10.1 years; 162.6 ± 7.1 cm; 58.7 ± 8.9 kg). Each subject voluntarily and randomly performed: a sit up test (SUT), a push up test (PUT), and a free weight squat test (ST), all till exhaustion. A multiple regression analysis was adopted for data analysis. Subsequently a percentile model for muscle endurance was developed. The 25th, 50th, and 75th percentile were identified as upper limit for low muscular endurance, average muscular endurance, and lower limit for high muscular endurance, respectively. Considering the sit up test as the dependent variable, the coefficients (R(2) = 0.23; r = 0.49; p squat test, respectively. Gender stratification showed regression coefficients of (R(2) = 0.19; r = 0.44; p < 0.001) for SUT vs. PUT, and (R(2) = 0.30; r = 0.56; p < 0.001) for SUT vs. ST in male; and (R(2) = 0.23; r = 0.49; p < 0.001) for SUT vs. PUT, and (R(2) = 0.34; r = 0.59; p < 0.001) for SUT vs. ST in female. The SUT showed low inter-relation with the other proposed tests indicating that the adoption of a single test for the global evaluation of muscle endurance is not the optimal approach. Moreover, the SUT was found to be inexpensive, safe, and appropriate for core muscle endurance measurement for both male and female.

Full Text Available Ovarian sex cord-stromal tumors arise from the stromal cells that surround and support the oocytes. Sertoli-Leydig cell tumors belong to this category of ovarian neoplasms. We present the case of a 38-year-old woman who was found to have a right ovarian mass. The mass was resected and diagnosed as Stage I Sertoli-Leydig cell tumor, retiform variant, following histopathologic and immunohistochemical examination. This case is unusual given the rarity of the retiform variant of Sertoli-Leydig cell tumor and the atypically older age of 38 years at presentation.

Lipoid pneumonia is an uncommon disease caused by the presence of lipid in the alveoli. Here we described a case of a 50-year-old woman with haemoptysis, cough and tachypnea, who was diagnosed with cholesterol pneumonia accompanying with pulmonary artery hypertension. The extremely high pulmonary artery pressure achieved, in this case, is alarming and should alert the physicians that the cholesterol pneumonia may be one of the underlying causes of pulmonary artery hypertension. After a treatment of methylprednisolone, her clinical symptoms were significantly improved, which suggested that steroid might be a promising therapeutic for patients with cholesterol pneumonia. © 2015 John Wiley & Sons Ltd.

Veterinary problems of endurance horses in England and Wales.

Science.gov (United States)

Nagy, A; Dyson, S J; Murray, J K

2017-05-01

Several studies have shown that a considerable proportion of horses are eliminated from endurance rides due to lameness and metabolic problems. Limited information is available on specific veterinary issues in endurance horses and there are no descriptive data on veterinary problems in a large population of endurance horses. The aim of this study was to describe veterinary problems occurring in endurance horses in England and Wales, the regions of the United Kingdom where endurance rides are organised and regulated by Endurance Great Britain (Endurance GB). A comprehensive online self-completed questionnaire was used for data collection (30th December 2015-29th February 2016) All members of Endurance GB who were the main rider of one or more endurance horses were eligible to participate. From the target population of 1209 horses, 190 questionnaires were completed by riders, resulting in a 15.7% response rate. The most common rider-reported veterinary problem was lameness, affecting 152/190 (80.0%) of endurance horses at some point during their careers and 101/190 (53.2%) of horses in the previous 12 months. Detailed information on the most recent episode of lameness was available for 147 horses. Seventy-six percent of these lameness episodes (112/147) had been initially identified by a veterinarian, but only 52% of these lameness episodes were investigated further by a veterinarian, despite the high proportion of horses affected by lameness and the proportion of horses with recurrent lameness episodes. The second most common veterinary problem was thoracolumbar region pain, followed by non-specific cough, skin disease and colic. Education of endurance riders may improve the number, quality and timing of veterinary investigations, especially for lameness and thoracolumbar region pain. Copyright © 2017 Elsevier B.V.

Bovine ketosis is a rare cause of metabolic acidosis. It is a starvation ketosis that appears in lactating woman. A 29-year-old woman had a previous gastric surgery one month ago while breastfeeding her 6-month child. She presented to emergency with dyspnea, fatigue, weight loss and anorexia. The explorations revealed a serious metabolic acidosis with a high anion gap, for which all other causes have been eliminated. A restrictive diet in lactating patients is a major risk of ketosis or bovine ketosis. Medico-surgical treatment of obesity during lactation seems unreasonable. Breastfeeding should be systematically sought before a medical and surgical management of obesity. With the spread of bariatric surgery, starvation ketosis is a cause of metabolic acidosis not to ignore. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

A Fatal Twist: Volvulus of the Small Intestine in a 46-Year-Old Woman

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available A 46-year-old woman presented to two emergency departments within 12 hours because of acute abdominal pain. Physical exam demonstrated tenderness and epigastric guarding. An ultrasound was interpreted as negative; she was discharged home. Later that evening, she was found dead. Postmortem exam revealed acute hemorrhagic necrosis of a segment of jejunum secondary to volvulus. Clinical clues suggesting presentations of small bowel volvulus are usually nonspecific; the diagnosis is typically confirmed at surgery. Her unremitting abdominal pain, persistent vomiting, and absolute neutrophilia were consistent with an acute process. The etiology of this volvulus was caused by an elastic fibrous band at the root of the jejunal mesentery. While congenital fibrous bands are rare in adults, this interpretation is favored for two reasons. First, the band was located 20 cm superior to postsurgical adhesions in the lower abdomen and pelvis. Second, there was no history of trauma or previous surgery involving the site of volvulus.

de Carlo, Talisa E; Adhi, Mehreen; Lu, Chen D; Duker, Jay S; Fujimoto, James G; Waheed, Nadia K

We report a case of widespread unilateral drusen in a healthy 31 year old Caucasian woman using multi-modal imaging including ultra-high resolution optical coherence tomography (UHR-OCT). Dilated fundus exam showed multiple drusen-like lesions in the posterior pole without heme or fluid. Fundus auto fluorescence demonstrated hyperautofluorescent at the deposits. Fluorescein angiography revealed mild hyperfluorescence and staining of the lesions. Spectral-domain optical coherence tomography (SD-OCT) OS showed accumulations in the temporal macula at Bruch's membrane. UHR-OCT provided improved axial resolution compared to the standard 5 μm on the commercial SD-OCT and confirmed the presence of deposits in Bruch's membrane, consistent with drusen. The retinal layers were draped over the excrescences but did not show any disruption.

Magnesium is known to act at the neuromuscular junction by inhibiting the presynaptic release of acetylcholine and desensitizing the postsynaptic membrane. Because of these effects, magnesium has been postulated to potentiate neuromuscular weakness. We describe the case of a 62-year-old woman with myasthenia gravis and a metastatic thymoma who was admitted to our intensive care unit for management of a myasthenic crisis. The patient's neuromuscular weakness worsened in association with standard intravenous magnesium replacement, and the exacerbated respiratory failure necessitated intubation, mechanical ventilation, and an extended stay in the intensive care unit. The effect of magnesium replacement on myasthenia gravis patients has not been well documented, and we present this case to increase awareness and stimulate research. In addition, we discuss the relevant medical literature.

A 44-year-old woman was brought to the ED from John F. Kennedy International Airport. The patient was returning with her son from a 3-month visit to Bangladesh. Her journey started with a 4-h flight from Dhaka, Bangladesh to Dubai, United Arab Emirates. She consumed 240 mL of whiskey during the flight. This was followed by a 14-h flight from Dubai to New York. According to the patient's son, she did not consume any alcohol during the second flight. The patient was in her usual state of health with normal mentation throughout her journey. Upon landing, she started complaining of shortness of breath. After disembarking, she was witnessed to have seizure-like activity with involuntary passage of urine, following which she collapsed. The patient was intubated by emergency medical services in the field.

Although thyroid hormone deficiency, either clinical or subclinical, is an established risk factor for cardiovascular disease, coronary ischemia in a premenopausal woman in her 30s is relatively rare. A 38-year-old woman was referred to our hospital with severe breathlessness and depressed consciousness. Physical examination found facial, abdominal, and pretibial edema; coarse hair, hoarse voice, and dry skin; engorged jugular veins; a distant heart sound; and reduced bilateral entry of air into the chest. Laboratory examinations revealed severe hypothyroidism, hyperlipidemia, and elevated serum levels of carcinoembryonic antigen (CEA) and carbohydrate antigen 125 (CA125). A computed tomography scan showed massive pleural and pericardial effusions. After 3 months of levothyroxine replacement therapy (initial dose: 12.5 microg/d; maintenance dose: 125 microg/d), all abnormal laboratory values associated with hypothyroidism returned to within normal ranges, with the exception of a transient and paradoxical rise in serum thyroid-stimulating hormone levels. However, 3 weeks after the initiation of therapy, the patient reported intermittent chest pains during the course of therapy, and a coronary artery angiogram revealed diffuse stenosis of all 3 branches. The patient underwent coronary artery bypass grafting, with subsequent improvement in coronary perfusion. Careful cardiovascular evaluation is recommended before the start of thyroid hormone replacement therapy. In addition, care should be taken in the interpretation of serum biomarkers of malignancy (eg, CEA, CA125) in patients with myxedema, as values may be elevated in a hypothyroid state. Long-standing hypothyroidism may be associated with severe coronary atherosclerosis, even in a relatively young, premenopausal woman. The potential adverse cardiovascular effects of thyroid hormone must be considered during replacement therapy, even in relatively young patients.

A case of POF in a 31-year-old woman with karyotype 47,XXX. The aim of the study was to discuss a case of POF in a 31-year-old patient with polysomy 47,XXX. The described karyotype is not usually associated with this characteristic physical phenotype. In some rare cases, menstrual disorders, sterility, secondary amenorrhoea, premature menopause, and low intelligence are found. Our observations revealed the necessity for cytogenetic examination in all women at reproductive age with symptoms of premature ovarian failure. According to the data found in literature, patients with POF and karyotype disorders belong to the risk group of premature death, mostly for cardiological reasons. Raising patient awareness about the risk may have a positive effect on quality of life and regularity of check-ups.

Age, sex and (the) race: gender and geriatrics in the ultra-endurance age.

Whyte, Greg

2014-01-01

Ultra-endurance challenges were once the stuff of legend isolated to the daring few who were driven to take on some of the greatest physical endurance challenges on the planet. With a growing fascination for major physical challenges during the nineteenth century, the end of the Victorian era witnessed probably the greatest ultra-endurance race of all time; Scott and Amundsen's ill-fated race to the South Pole. Ultra-endurance races continued through the twentieth century; however, these events were isolated to the elite few. In the twenty-first century, mass participation ultra-endurance races have grown in popularity. Endurance races once believed to be at the limit of human durability, i.e. marathon running, are now viewed as middle-distance races with the accolade of true endurance going to those willing to travel significantly further in a single effort or over multiple days. The recent series of papers in Extreme Physiology & Medicine highlights the burgeoning research data from mass participation ultra-endurance events. In support of a true 'mass participation' ethos Knetchtle et al. reported age-related changes in Triple and Deca Iron-ultra-triathlon with an upper age of 69 years! Unlike their shorter siblings, the ultra-endurance races appear to present larger gender differences in the region of 20% to 30% across distance and modality. It would appear that these gender differences remain for multi-day events including the 'Marathon des Sables'; however, this gap may be narrower in some events, particularly those that require less load bearing (i.e. swimming and cycling), as evidenced from the 'Ultraman Hawaii' and 'Swiss Cycling Marathon', and shorter (a term I used advisedly!) distances including the Ironman Triathlon where differences are similar to those of sprint and endurance distances i.e. c. 10%. The theme running through this series of papers is a continual rise in participation to the point where major events now require selection races to remain

INFLUENCE OF PHYSICAL TRAINING ON CARDIORESPIRATORY ENDURANCE IN PREADOLESCENT AGE

Directory of Open Access Journals (Sweden)

Full Text Available Cardiorespiratory or aerobic endurance is the ability of the whole body to sustain physical activity for an extended period of time, involving relatively large groups of muscles. The attitudes on the possible impact of training on cardiorespiratory endurance in preadolescents are contradictory. Our study enrolled 195 boys aged 11 to 12 years. Experimental group (n=92 consisted of the children who had been involved with planned and programmed water polo training for at least two years. Control group (n=103 consisted of schoolchildren who only had had regular physical education in schools. Our investigation protocol included standardized anthropometric measurements and tests, performed respecting the appropriate protocols. Statistical analysis of the results demonstrated that there were no significant differences in age and relative values of oxygen consumption (VO2peak. Body height and mass, as well as the skinfold thickness, were significantly higher in experimental group subjects. The values of absolute VO2peak, FVC and FEV1.0 were also significantly higher in the examinees involved with water polo training. These findings stress the importance of a systematic training process even in this early period of growth and development in order for the trainees to acquire important functional advantages. We believe that a properly planned and programmed physical training can significantly contribute to the development of cardiorespiratory endurance even as early as preadolescent age.

There is consensus that the modern human lineage appeared in Africa before 100,000 years ago. But there is debate as to when cultural and cognitive characteristics typical of modern humans first appeared, and the role that these had in the expansion of modern humans out of Africa. Scientists rely on symbolically specific proxies, such as artistic expression, to document the origins of complex cognition. Advanced technologies with elaborate chains of production are also proxies, as these often demand high-fidelity transmission and thus language. Some argue that advanced technologies in Africa appear and disappear and thus do not indicate complex cognition exclusive to early modern humans in Africa. The origins of composite tools and advanced projectile weapons figure prominently in modern human evolution research, and the latter have been argued to have been in the exclusive possession of modern humans. Here we describe a previously unrecognized advanced stone tool technology from Pinnacle Point Site 5-6 on the south coast of South Africa, originating approximately 71,000 years ago. This technology is dominated by the production of small bladelets (microliths) primarily from heat-treated stone. There is agreement that microlithic technology was used to create composite tool components as part of advanced projectile weapons. Microliths were common worldwide by the mid-Holocene epoch, but have a patchy pattern of first appearance that is rarely earlier than 40,000 years ago, and were thought to appear briefly between 65,000 and 60,000 years ago in South Africa and then disappear. Our research extends this record to ~71,000 years, shows that microlithic technology originated early in South Africa, evolved over a vast time span (~11,000 years), and was typically coupled to complex heat treatment that persisted for nearly 100,000 years. Advanced technologies in Africa were early and enduring; a small sample of excavated sites in Africa is the best explanation for any

To describe and discuss the use of maintenance electroconvulsive therapy (ECT) in a young woman with Down syndrome and depression with catatonia. Clinical case report. A 23-year-old woman with Down syndrome (mosaic type) and a 4-year history of depressed mood triggered by adverse life events presented with mutism, psychomotor retardation, and compromised oral intake. Multiple trials of antidepressant medications were either ineffective or complicated by adverse reactions. She improved rapidly with a course of bilateral ECT but required maintenance ECT to sustain recovery. A series of premorbid, morbid, and post-treatment drawings by the young woman highlight the efficacy of treatment. Electroconvulsive therapy was found to be a safe and effective treatment for life-threatening mental illness in a young woman with Down syndrome who had failed multiple trials of antidepressant medications. This case highlights the importance of considering catatonia as a diagnosis in persons with Down syndrome and the effectiveness of electroconvulsive treatment.

Non-traumatic myositis ossificans mimicking a malignant neoplasm in an 83-year-old woman: a case report

Nishio Jun

2010-08-01

Full Text Available Abstract Introduction Myositis ossificans is a benign, self-limiting condition that usually affects young, athletically active men. To the best of our knowledge, this case report describes the oldest recorded patient with myositis ossificans. Case presentation Our patient was an 83-year-old Japanese woman who presented with a one week history of a palpable mass in the left thigh. She had a history of surgery for transverse colon cancer and lung cancer at the ages of 73 and 80, respectively. Clinical and radiological examinations suggested a malignant neoplasm such as metastatic carcinoma or extraskeletal osteosarcoma. A diagnosis of myositis ossificans was made by core needle biopsy. Our patient was asymptomatic and had no recurrence at one year follow-up. Conclusion Clinicians should consider myositis ossificans as a possible diagnosis for a soft tissue mass in the limb of an older patient, thereby avoiding unnecessarily aggressive therapy.

One of the supporting factors to have good aerobic endurance requires high VO2 max levels supported by good quality and quantity level of Haematology parameter especially such as erythrocytes, hematocrit and hemoglobin. One of the components in hemoglobin is iron which functions as theoxygen transport to parts of all body required in the process of metabolism. The objective of this research was to find out the difference between VO2 Max and Haematology parameter between iron supplying and no iron supplyingonmenstrual woman. The type of this research is quasi experimental research with non-randomized control group Pretest-Postest Design. The subjectsarethe studentsat faculty of Sports Sciences, Medan State University with the criteria of female gender, monthly regular menstrual cycle, having the level of health and the level of training, willing to be a sample by filling out informed consent. The total number of research subjectsis twenty students, divided into two groups namely the treatment group and the control group. The hematology parameter was measuredby Haemotology analyzer and VO2 Max was measured by multi-stage run. The result showed that there was a significant effect of iron supplyingon the increase of erythrocyte level on menstrual women, hemotocrit, haemoglobin and an increase in VO2 Max. Iron supplying on menstrual woman has the effect on the increase of erythrocyte, hematocrit, hemoglobin level and VO2 Max

Full Text Available The predictive relationship between muscular strength and endurance and cardio-metabolic health, independent from aerobic fitness, is not clear in disadvantaged Hispanic children. The purpose of this study was to examine the predictive relationship between muscular strength and endurance and clustered cardio-metabolic risk, controlling for aerobic fitness, in Hispanic children from low-income schools. Participants were 320 Hispanic children (Mean age = 10.1 ± 1.1 years; 164 girls, 156 boys recruited during the 2014–2015 and 2015–2016 academic years from five low-income schools from the state of Utah in the U.S. Muscular strength and endurance was assessed using the push-up and curl-up tests and estimated VO2 Peak was calculated from the Progressive Aerobic Cardiovascular Endurance Run. A clustered metabolic syndrome composite score (MetS was calculated from cardio-metabolic health measurements consisting of HDL cholesterol, triglycerides, waist circumference, blood glucose, and mean arterial pressure (MAP. Multi-level general linear mixed effects models were used to examine the predictive relationship between muscular strength and endurance and MetS, controlling for the effect of aerobic fitness and the clustering of children within classrooms and schools. Children who were in the middle and upper tertiles for muscular strength and endurance associated with a lower (more favorable MetS score (middle tertile: β = −2.59, 95% C.I. [−4.23, −0.95], p < 0.05; upper tertile: β = −1.57, 95% C.I. [−3.20, −0.16], p < 0.05. The results suggest that higher levels of muscular strength and endurance relate to lower cardio-metabolic risk, independent of aerobic fitness, in Hispanic children from low-income schools.

Obesity is a risk factor of nonalcoholic fatty liver disease. Although the standard therapy for obesity involves physical exercise, well-planned studies of the changes in liver function in response to different exercise intensities in obese subjects are scarce. The aim of the present study was to examine a question of how does exercise mode affect the liver function. 44 women with abdominal obesity were randomized into two exercise groups: endurance (group A) and endurance-strength (group B). Women in each group exercised for 60min 3 times/week for a 3-month period. Markers of liver function: serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyltranspeptidase (GGT), alkaline phosphatase (ALP) activities, and bilirubin levels were quantified. We found significant differences in ALT (pexercise. Blood ALT and AST tended to decrease in group B, increase in group A. Significant reduction in serum GGT level after exercise in both groups was observed (pexercise led to changes in serum ALP activity and total or direct bilirubin level. However, endurance-strength training resulted in significant decreases in serum indirect bilirubin (pexercise (group B). The mode of exercise does matter: endurance-strength exercise led to a greater improvement, compared to endurance exercise, in the liver function in women with abdominal obesity.

Wild and exotic animal attacks are not common in the United States. Animal-related injuries in the United States are usually caused by dog bites, followed by cattle and horse injuries. Exotic animal attacks can occur when the animals are provoked, depressed, or housed improperly by owners. We report the case of a 51-year-old woman who sustained multiple systemic traumatic injuries after she was pinned to a fence by an elephant's trunk. Upon arrival in the emergency department, she was hypothermic with a temperature of 35.1ºC (95.1ºF), hypotensive to 94/60 mm Hg after 5 L crystalloid, tachycardic at 108 beats/min, and intubated with oxygen saturation of 100%. Tranexamic acid was administered in addition to starting a massive transfusion protocol. Injuries included bilateral multiple rib fractures, left abdominal wall degloving injury, right pneumothorax, right hemothorax, left chest wall puncture wound, grade IV splenic laceration, 3 grade III liver lacerations, retroperitoneal hematoma, and degloving injuries to bilateral posterior thighs requiring more than 30 operations. Why should an emergency physician be aware of this? Several factors need to be considered when evaluating animal-related injuries, including type, age, and sex of the animal. Multisystem traumatic injuries should be assumed when a large animal is involved. Prehospital care and transport time are vital to a patient's survival in both urban and rural settings. During the initial resuscitation, administering antibiotics tailored to the specific animal can greatly decrease risk of infection and morbidity. Additionally, tetanus immunoglobulin, tetanus toxoid, and rabies immunoglobulin and vaccine may be needed, unless the victim has been previously vaccinated.

Minoan Civilization (3000-1150 BC) was the first European civilization on the GREEK island of Crete. Fabulous architectonical constructions like great palaces, wonderful frescoes, and pottery as well as jewellery characterize this amazing civilization. According to all existing descriptions from ancient Greek historians and philosophers like Plato, Thucydides, Strabon but also from all the archaeological findings men and women lived freely and peacefully participating equal in all daily activities, sports, and games. The women were predominating. Minoan women enjoyed a higher social status than other women in later civilizations. Investigation of all the existing data concerning the Minoan culture. Archaeological databases, as well as data from the National University of Athens and other Greek historical institutions were collected and analyzed in order to present the Minoan culture. The Minoic civilization represents a paradigm of a well being society in which the woman played a dominant role. She was the 'mother' but also the 'active woman', who participated in all city activities. Four thousand years later a prototype of a society in which the role of the mother was recognized in an admirably way remains a magnificent paradigm.

Alice Walker’s Womanism in Meridian

GAN Lin

2015-01-01

Meridian is one of Alice Walker’s early work. It tells a story that happened in the American south during the 1960s and early 70s’. It describes the life of the main character, Meridian Hill, a black woman from a southern town, who got out of the oppression of white society, and ends up in participate in Civil Rights Movement. The paper firstly illustrates the soul of womanism—anti-sexism, anti-racism, sisiterhood as well as the maternity love, then analyzes how these theories permeated into the novel—Meridian. The paper paid attention to the function of this novel on the improvement of Alice Walker ’s womanism. In proving that womanism not only permeates into Meridian, but also improved womanism from many perspectives, it comes to the conclusion that Meridian is a novel to improve Alice Walker’s womanism, it serves as the good novel to highlight the African Culture, and made a great contribution for the encouragement of black women to seek for freedom in the society.

Full Text Available To inform healthcare professionals of a rare serious reaction leading to leg amputation following intramuscular injection of iron dextran and report comments for preventing such reactions.A case of leg amputation following intramuscular injection of iron dextran reported to Iranian Pharmacovigilance Center was reviewed. Patient and reaction data was collected by assessing the reported yellow card, patient chart review and interviewing with patient and physicians. World Health Organization definition for serious reactions was used to determine the seriousness of the reaction. Naranjo algorithm was used to determine probability scale. The probability of the reaction was determined based on questionnaire of Schumock et al. The studied case is classified as a rare and serious but preventable reaction induced by intramuscular injection of iron dextran in a 32 year old woman. The probability of the reaction is appeared to be “probable” based on Naranjo algorithm. It seems that Iron dextran could cause serious and life threatening adverse effects. It is necessary for healthcare professionals to be informed of such rare but serious reaction in order to apply preventive actions.

Restrepo, Diana; Duque, Marle; Montoya, Laura; Hoyos, Catalina

To describe a case of legal and voluntary interruption of pregnancy due to a mental health risk in the mother. However, the foetus survived and the mother decided to care for the child. Description of the case and a non-systematic review of the relevant literature. A multiparous woman of 38 years with unknown gestational age who requests legal and voluntary interruption of pregnancy. After abortion a male child born of 1050 grams was born, intubated and admitted to intensive care. Subsequently, the mother, without the mental problems that led to abortion, gradually assumed the care of the child. To address this complex case, several aspects are analysed: first, the change of mind of a woman in her desire to be a mother. Second, the disappearance of mental symptoms in the immediate postpartum. Third, the need to review the clinical, ethical and legal foundations of the legal ruling that allows therapeutic abortion in Colombia. Copyright © 2016 Asociación Colombiana de Psiquiatría.

The authors describe an unusual case of metastatic thyroid follicular adenocarcinoma presenting with sciatica in a 79-year-old woman. The primary thyroid tumour was undiagnosed until this clinical presentation. The patient gave a short history of back pain and right-sided sciatica, which was progressive and nocturnal in nature. Neuroimaging revealed an enhancing intradural mass lesion, which was completely excised through a right L1-L3 hemilaminectomy. Histopathological examination of the excised tissue revealed a follicular thyroid carcinoma. Subsequent metastatic investigation revealed a heterogeneously attenuating mixed solid cystic mass in a retrosternal thyroid gland, with multiple solid pulmonary nodules suggestive of metastatic disease. She opted for palliative radiotherapy for the primary thyroid cancer and made remarkable postoperative improvement. The authors conclude that surgical treatment of solitary metastatic lesion may produce good symptomatic relief irrespective of patient\\'s age and primary pathology, while emphasising the need for detailed clinical evaluation of patients with \\'red flag\\' symptoms.

Population aging is a demographic reality for Brazil. Consequently, in the next years it is expected a progressive increase in seeking health care services in the country by women with complaints related to climacterium. Parallel to it, assistance at this part of woman's life has been going through a paradigm shift which has imposed to health professionals a change of attitude in relation to this stage of woman's life. Today it is acknowledged that the climacterium is influenced by biological, psychosocial and cultural factors, whose knowledge is fundamental for planning a more qualified and humanized care. This article proposes a reflection on the paradigm shifts in assistance at climacterium, highlighting important aspects as multidisciplinarity and interdisciplinarity, so as to serve better this portion of population, and provide it with more integrated and individualized care, bringing together knowledge and sensitivity, and always aiming at a better quality of life.

Full Text Available Front of exercise, the organic systems may suffer water-electrolyte and acid-base imbalances, particularly in the case of blood gases, demonstrating variations from different causes, whether respiratory and/or metabolic. Understanding the physiological adaptations to exercise is essential in the search for the optimum performance. In this way, this study measured the venous blood gases (pO2, pCO2, as well as the oxygen saturation (SatO2 in healthy equines, Arabian horses finalists in 90km endurance races. A total of fourteen Arabian horses were evaluated, nine males and five females, between six and 12 years old, finalists in 90km endurance races. There was a significant reduction in pO2, pCO2 and SatO2 after the exercise, however, the values remained within the normality range, and did not change the athletic performance of the animals, indicating a temporary alteration, assuming thus a character of physiological response to the exercise performed. The equines, finalists in 90 Km endurance races, demonstrated efficient ventilatory process, without any alterations in the athletic performance, being adapted to the type of exercise imposed.

2015-12-01

Full Text Available This research attempts to provide a fresh evaluation of a testimony in general and an evaluation of the weight of woman's testimony in particular. By using an empirical methodology, the research responds to the equality issue between women and men as competent witnesses, as Western jurisprudence claims, and the issue of non-equality between women and men as competent witnesses, as Islamic Sharia scholars claim. This study found numerous results, one of which was that womanhood affects a woman's ability to bear in mind a witnessed fact. Therefore, womanhood should be dealt with as a discrediting her testimony factor. Another result was that woman's testimony is admissible, even if she was alone; because womanhood is a factor relating to the weight of a testimony not a stipulation for the admissibility of testimony. Moreover, the research classified testimony in regard to its weight into two kinds. The first kind is Attestation, which always requires corroboration from a man or woman to renders it admissible as evidence. The second kind is Testimony, which does not generally require corroboration, even if the witness is a woman. However, corroboration may be necessary if the testimony has been affected by any discrediting factor regardless the sex of the witness. One more result of the research was that corroboration for testimony is affected by womanhood in certain cases, can be attained by summoning another woman as a witness, inferring factual presumptions, or examining the surrounding circumstances.

To assess changes in muscular strength and endurance after microgravity exposure, NASA measures isokinetic strength and endurance across multiple sessions before and after long-duration space flight. Accurate interpretation of pre- and post-flight measures depends upon the reliability of each measure. The purpose of this study was to evaluate the test-retest reliability of the NASA International Space Station (ISS) isokinetic protocol. Twenty-four healthy subjects (12 M/12 F, 32.0 +/- 5.6 years) volunteered to participate. Isokinetic knee, ankle, and trunk flexion and extension strength as well as endurance of the knee flexors and extensors were measured using a Cybex NORM isokinetic dynamometer. The first weekly session was considered a familiarization session. Data were collected and analyzed for weeks 2-4. Repeated measures analysis of variance (alpha=0.05) was used to identify weekly differences in isokinetic measures. Test-retest reliability was evaluated by intraclass correlation coefficients (ICC) (3,1). No significant differences were found between weeks in any of the strength measures and the reliability of the strength measures were all considered excellent (ICC greater than 0.9), except for concentric ankle dorsi-flexion (ICC=0.67). Although a significant difference was noted in weekly endurance measures of knee extension (p less than 0.01), the reliability of endurance measure by week were considered excellent for knee flexion (ICC=0.97) and knee extension (ICC=0.96). Except for concentric ankle dorsi-flexion, the isokinetic strength and endurance measures are highly reliable when following the NASA ISS protocol. This protocol should allow accurate interpretation isokinetic data even with a small number of crew members.

A singularly unfeminine profession one woman's journey in physics

CERN Document Server

Gaillard, Mary K

2015-01-01

In 1981 Mary K Gaillard became the first woman on the physics faculty at the University of California at Berkeley. Her career as a theoretical physicist spanned the period from the inception — in the late 1960s and early 1970s — of what is now known as the Standard Model of particle physics and its experimental confirmation, culminating with the discovery of the Higgs particle in 2012. A Singularly Unfeminine Profession recounts Gaillard's experiences as a woman in a very male-dominated field, while tracing the development of the Standard Model as she witnessed it and participated in it. The generally nurturing environment of her childhood and college years, as well as experiences as an undergraduate in particle physics laboratories and as a graduate student at Columbia University — which cemented her passion for particle physics — left her unprepared for the difficulties that she confronted as a second year graduate student in Paris, and later at CERN, another particle physics laboratory near Geneva,...

Background Endurance capacity, assessed by 1000-meter (1000 m) run of male university students, is an indicator of cardiovascular fitness in Chinese students physical fitness surveillance. Although cardiovascular fitness is related to endothelial function closely in patients with cardiovascular diseases, it remains unclear whether endurance capacity correlates with endothelial function, especially with circulating endothelial microparticles (EMPs), a new sensitive marker of endothelial dysfunction in young students. The present study aimed to investigate the relationship between endurance capacity and endothelial function in male university students. Methods Forty-seven healthy male university students (mean age, 20.1±0.6 years; mean height, 172.4±6.3 cm; and mean weight, 60.0±8.2 kg) were recruited in this study. The measurement procedure of 1000 m run time was followed to Chinese national students Constitutional Health Criterion. Endothelium function was assessed by flow-mediated vasodilation (FMD) in the brachial artery measured by ultrasonic imaging, and the level of circulating EMPs was measured by flow cytometry. Cardiovascular fitness indicator - maximal oxygen uptake (VO2 max) - was also measured on a cycle ergometer using a portable gas analyzer. Results 1000 m run time was correlated with VO2max (r = −0.399, p0.05). Conclusion The correlations between endurance capacity or cardiovascular fitness and endothelial function were not found in healthy Chinese male university students. These results suggest that endurance capacity may not reflect endothelial function in healthy young adults with well preserved FMD and low level of circulating CD31+/CD42-EMPs. PMID:25101975

Telomere length and long-term endurance exercise: does exercise training affect biological age? A pilot study.

Directory of Open Access Journals (Sweden)

Ida Beate Ø Østhus

Full Text Available BACKGROUND: Telomeres are potential markers of mitotic cellular age and are associated with physical ageing process. Long-term endurance training and higher aerobic exercise capacity (VO(2max are associated with improved survival, and dynamic effects of exercise are evident with ageing. However, the association of telomere length with exercise training and VO(2max has so far been inconsistent. Our aim was to assess whether muscle telomere length is associated with endurance exercise training and VO(2max in younger and older people. METHODS: Twenty men; 10 young (22-27 years and 10 old (66-77 years, were studied in this cross-sectional study. Five out of 10 young adults and 5 out of 10 older were endurance athletes, while other halves were exercising at a medium level of activity. Mean telomere length was measured as telomere/single copy gene-ratio (T/S-ratio using quantitative real time polymerase chain reaction. VO(2max was measured directly running on a treadmill. RESULTS: Older endurance trained athletes had longer telomere length compared with older people with medium activity levels (T/S ratio 1.12±0.1 vs. 0.92±0.2, p = 0.04. Telomere length of young endurance trained athletes was not different than young non-athletes (1.47±0.2 vs. 1.33±0.1, p = 0.12. Overall, there was a positive association between T/S ratio and VO(2max (r = 0.70, p = 0.001. Among endurance trained athletes, we found a strong correlation between VO(2max and T/S ratio (r = 0.78, p = 0.02. However, corresponding association among non-athlete participants was relatively weak (r = 0.58, p = 0.09. CONCLUSION: Our data suggest that VO(2max is positively associated with telomere length, and we found that long-term endurance exercise training may provide a protective effect on muscle telomere length in older people.

Full Text Available The pathogenesis of disease progression in drug-refractory epilepsy is poorly understood. We report the case of a young woman with a four-year history of epilepsy that progressed rapidly as evidenced by the development of progressive focal cortical atrophy. She underwent biopsy that showed perinatal ischemia and a prominent inflammatory response, including T-cell infiltration and microglial activation. There was no consensus reached on the final diagnosis although the hypothesis of dual pathology (adult variant of Rasmussen's encephalitis and perinatal stroke was considered. The possible role of inflammation in the progression of epilepsy caused by a “static” lesion (perinatal stroke is discussed.

The present study investigated the effects of a 12-week endurance-training intervention on salivary proteins and upper respiratory tract symptoms (URS) in 25 young men. Saliva samples of 25 recreational male endurance runners (age 34.6 years, body mass index = 23.8 kg·m(-2), peak aerobic capacity = 47.2 mL·kg(-1)·min(-1)) were collected before (PRE) and after (POST) the training intervention, in a fasting state, as well as both before and after a maximal incremental treadmill run. The training consisted of both continuous and interval training sessions, 4-6 times per week based on the polarized training approach. Participants filled in Wisconsin Upper Respiratory Symptom Survey-21 and were retrospectively divided into 2 groups according to whether they reported URS (URS group, n = 13) or not (HEALTHY group, n = 12). Basal salivary immunoglobulin A (sa-sIgA) levels were significantly higher (+70%, p < 0.05) in the HEALTHY group both at PRE and POST whereas no significant differences were observed in salivary immunoglobulin M, salivary immunoglobulin G, lysozyme, or salivary α-amylase activity (sAA). Sa-sIgA concentration at PRE significantly correlated with the number of sick-days (R = -0.755, p < 0.001) in all subjects. The incremental treadmill run acutely increased sAA significantly (p < 0.05) at PRE (200%) and POST (166%) in the HEALTHY group but not in the URS group. This study demonstrated that subjects, who experienced URS during the 12 weeks of progressive endurance training intervention, had significantly lower basal sa-sIgA levels both before and after the experimental endurance training period. In addition to sa-sIgA, acute sAA response to exercise might be a possible determinant of susceptibility to URS in endurance runners.

Alveolar Rhabdomyosarcoma in a 69-Year-Old Woman Receiving Glucagon-Like Peptide-2 Therapy

Directory of Open Access Journals (Sweden)

Laura E. Zyczynski

2015-01-01

Full Text Available A 69-year-old woman was diagnosed with alveolar rhabdomyosarcoma (ARMS of the nasopharynx. She has a history of catastrophic thromboembolic event in the abdomen that caused short-gut syndrome and dependence on total parenteral nutrition (TPN twelve hours per day. She was treated for short-gut syndrome with teduglutide, a glucagon-like peptide-2 (GLP-2 analog, which led to reduction of TPN requirements. However, a few months later, she developed metastatic alveolar rhabdomyosarcoma. Though a causative relationship is unlikely between the peptide and ARMS due to the brief time course between teduglutide therapy and sarcoma diagnosis, neoplastic growth may have been accelerated by the GLP-2 analog, causing release of IGF-1. The transmembrane receptor for IGF-1 is frequently overexpressed in ARMS and is implicated in cell proliferation and metastatic behavior. This case describes a rare incidence of metastatic alveolar rhabdomyosarcoma in a sexagenarian and possibly the first case reported associated with the use of teduglutide. Teduglutide was discontinued due to a potential theoretical risk of acceleration of sarcoma growth, and the patient’s rhabdomyosarcoma is in remission following sarcoma chemotherapy.

Spontaneous traumatic macular hole closure in a 50-year-old woman: a case report

Rotsos Tryfon

2011-07-01

Full Text Available Abstract Introduction Traumatic macular holes (TMH are well-known complications of ocular contusion injury. Spontaneous closure occurs in approximately 50% of cases, but rarely after the age of thirty. We report a case of spontaneous closure of a full thickness macular hole due to a blunt trauma and we suggest possible mechanisms for this closure. Case presentation A 50-year-old Greek woman was referred with a history of reduced best-corrected visual acuity after blunt trauma to her right eye. Diagnosis was based on fundoscopic, optical coherence tomography as well as fluorescein angiography findings with follow-up visits at two days, 20 days and five months. Fundoscopy revealed a full-thickness TMH with a minor sub-retinal hemorrhage and posterior vitreous detachment. The presence of a coagulum in the TMH base was observed. Subsequently, TMH closure was observed. Conclusion The clot in the TMH base, potentially a hemorrhage by-product containing a significant quantity of platelets, may have simulated the clot observed after autologous serum use, thus facilitating a similar effect. This may have stimulated glial cell migration and proliferation, thus contributing to spontaneous hole closure.

To investigate the late effects of radiation on child-bearing women, a follow-up study was performed on a 39-year-old survivor 16 years after a 60 Co radiation accident. The woman, Fang, was 19 weeks pregnant at the time of exposure. Physical examinations, a full range of clinical laboratory and imaging tests, as well as cytogenetic analyses were conducted to evaluate Fang's current health conditions. Fang shows the appearance of premature ageing and has a decreased menstrual period. Laboratory studies and imaging tests suggest nodular goitre disease and osteoporosis. Otherwise, no apparent abnormalities were found in the major organs. No malignant tumours were detected by either tumour markers or imaging tests. However, the existence of chromosome aberrations warrants long-term follow-up for tumour incidence in the future. Fang became pregnant 8 years after the accident, but suffered a miscarriage due to the death of the foetus at 6 months into the pregnancy. In conclusion, our findings suggest that the intrauterine death of the foetus might be associated with the previous exposure. There is no evidence of malignant tumours as of the date of the follow-up study. Non-cancerous diseases, i.e. thyroid disease and osteoporosis, which may be related to radiation exposure, are the major manifestations of the long-term effects of the accident. (note)

Poor insight is a common, multidimensional phenomenon in patients with schizophrenia, associated with poorer outcomes and treatment non-adherence. Yet scant research has investigated the neuronal correlates of insight into symptoms (IS), a dimension of insight that may be particularly significant in enduring schizophrenia. Sixty-six patients with enduring schizophrenia (duration >4years) and 33 healthy controls completed MRI scanning and IQ, depression, and anxiety assessments. The Scale to Assess Insight-Expanded (SAI-E) measured insight into patients' four most prominent symptoms and patients were classified into two groups: low IS (0-2; n=33), and high IS (>2; n=33). We evaluated the association between cortical thickness (CT) and insight into symptoms using two methods: (1) a between-patients region-of-interest analysis in the insula, superior temporal gyrus (STG) and frontal lobe; and (2) a whole-brain exploratory regression between patient and controls. Brain regions were segmented using a neuroanatomical atlas and vertex-wise CT analyses were conducted with CIVET, covaried for age and sex. ROI analysis revealed thinner insula cortex in patients with low IS (pinsight-related differences in CT that has been previously unexplored in enduring schizophrenia. Copyright © 2015 Elsevier B.V.

Physiologic changes, including neurological or pseudo-neurological symptoms, occur across identity states in dissociative identity disorder DID) and can be objectively measured. The idea that dissociative phenomena might be associated with changes in brain function is consistent with research on the brain effects of hypnosis. The authors report a case of psycho-physiologic differences among 4 alter personalities manifested by a 35-year-old woman with DID. Differences in visual acuity, frequency of pendular nystagmus, and handedness were observed in this patient both when the alter personalities appeared spontaneously and when elicited under hypnosis. The authors consider several diagnostic possibilities for these findings and discuss whether prevailing treatment recommendations for DID patients could possibly be modified to ameliorate such visual and neurologic symptoms.

Full Text Available In order to determine physical fitness differences in students with different cardiorespiratory endurance levels, a study was conducted on a sample of students of the Faculty of Sport and Physical Education at the University of Nis. The sample was divided into two subsamples, where the first subsample comprised 27 female students and the other 35 male students. Physical fitness was assessed using eight tests from the Eurofit battery of tests: the single-leg balance test - for the assessment of general balance, plate tapping - for the assessment of speed of movement, sit-and-reach - for the assessment of flexibility, the standing broad jump - for the assessment of explosive strength, the handgrip test - for the assessment of static strength, sit-ups - for the assessment of repetitive trunk strength, the bent arm hang - for the assessment of muscular endurance and the 10x5 meter shuttle run - for the assessment of the speed/agility. Cardiorespiratory endurance was estimated with the aid of 20 m endurance shuttle-run test. Based on the level of cardiorespiratory endurance, the participants in each subsample, were divided into three groups using a cluster analysis: high (VKRI, average (PKRI and low level (NKRI. The physical fitness differences of students with different cardiorespiratory endurance levels were calculated using the one-way analysis of variance. The results showed that there were no differences in physical fitness of students with different cardiorespiratory endurance levels. Based on the results it can be concluded that the level of cardiorespiratory endurance does not affect the components of physical fitness among students of both sexes.

Overexpression of interleukin-15 (IL-15) in mice exerts similar metabolic changes in muscle as seen with endurance exercise. Muscular IL-15 production has been shown to increase in mice after weeks of regular...... endurance running. With the present study we aimed to determine if muscular IL-15 production would increase in human male subjects following 12 weeks of endurance training. In two different studies we obtained plasma and muscle biopsies from young healthy subjects performing: (1) 12 weeks of ergometer...... weeks of regular endurance training induced a 40% increase in basal skeletal muscle IL-15 protein content (p...

The effects of elevated pain inhibition on endurance exercise performance

Directory of Open Access Journals (Sweden)

Andrew Flood

2017-03-01

Full Text Available Background The ergogenic effects of analgesic substances suggest that pain perception is an important regulator of work-rate during fatiguing exercise. Recent research has shown that endogenous inhibitory responses, which act to attenuate nociceptive input and reduce perceived pain, can be increased following transcranial direct current stimulation of the hand motor cortex. Using high-definition transcranial direct current stimulation (HD-tDCS; 2 mA, 20 min, the current study aimed to examine the effects of elevated pain inhibitory capacity on endurance exercise performance. It was hypothesised that HD-tDCS would enhance the efficiency of the endogenous pain inhibitory response and improve endurance exercise performance. Methods Twelve healthy males between 18 and 40 years of age (M = 24.42 ± 3.85 were recruited for participation. Endogenous pain inhibitory capacity and exercise performance were assessed before and after both active and sham (placebo stimulation. The conditioned pain modulation protocol was used for the measurement of pain inhibition. Exercise performance assessment consisted of both maximal voluntary contraction (MVC and submaximal muscular endurance performance trials using isometric contractions of the non-dominant leg extensors. Results Active HD-tDCS (pre-tDCS, −.32 ± 1.33 kg; post-tDCS, −1.23 ± 1.21 kg significantly increased pain inhibitory responses relative to the effects of sham HD-tDCS (pre-tDCS, −.91 ± .92 kg; post-tDCS, −.26 ± .92 kg; p = .046. Irrespective of condition, peak MVC force and muscular endurance was reduced from pre- to post-stimulation. HD-tDCS did not significantly influence this reduction in maximal force (active: pre-tDCS, 264.89 ± 66.87 Nm; post-tDCS, 236.33 ± 66.51 Nm; sham: pre-tDCS, 249.25 ± 88.56 Nm; post-tDCS, 239.63 ± 67.53 Nm or muscular endurance (active: pre-tDCS, 104.65 ± 42.36 s; post-tDCS, 93.07 ± 33.73 s; sham: pre-tDCS, 123.42 ± 72.48 s; post

Weiss, C; Santander, J; Torres, R

2013-01-01

The following case study describes a 22-year-old woman with depression and symptoms of psychosis who developed neuroleptic malignant syndrome after using Risperidone, thus requiring life support equipment and Bromocriptine, later recovering after seven days. From a psychiatric and neurological point of view, however, the persistence of catatonic syndrome and Cotard syndrome delusions was observed, based on assertions such as "I do not have a heart," "my heart is not beating," "I can not breathe," "I am breaking apart," "I have no head" (ideas of negation) and statements about the patient being responsible for the "death of the whole world" (ideas of enormity). Brain NMR revealed leukoencephalopathy, interpreted as scar lesions caused by perinatal neurological damage, after discarding other pathologies. The patient responded well to electroconvulsive therapy after 11 sessions. Organic vulnerability to these syndromes, as well as their coexistence and clinical differentiation is discussed in the light of the data observed.

Full Text Available Abstract Background Disseminated mycobacterium avium complex (MAC occurs mainly in immunocompromised hosts, which is associated with abnormal cellular immunity. Case presentation A 26-year-old pregnant woman presented with fever and general weakness. Miliary lung nodules were noted on chest X-ray. Under the impression of miliary tuberculosis, anti-tuberculosis medication was administered. However, the patient was not improved. Further work-up demonstrated MAC in the sputum and placenta. The patient was treated successfully with clarithromycin-based combination regimen. Conclusion This appears to be the first case of disseminated MAC in an otherwise healthy pregnant woman. Clinicians should be alert for the diagnosis of MAC infection in diverse clinical conditions.

Bradfield, Zoe; Duggan, Ravani; Hauck, Yvonne; Kelly, Michelle

2018-04-01

Midwives being 'with woman' is embedded in professional philosophy, standards of practice and partnerships with women. In light of the centrality of being 'with woman' to the profession of midwifery, it is timely to review the literature to gain a contemporary understanding of this phenomenon. This review synthesises research and theoretical literature to report on what is known and published about being 'with woman'. A five step framework for conducting an integrative literature reviews was employed. A comprehensive search strategy was utilised that incorporated exploration in electronic databases CINAHL, Scopus, Proquest, Science Direct and Pubmed. The initial search resulted in the retrieval of 2057 publications which were reduced to 32 through a systematic process. The outcome of the review revealed three global themes and corresponding subthemes that encompassed 'with woman': (1) philosophy, incorporated two subthemes relating to midwifery philosophy and philosophy and models of care; (2) relationship, that included the relationship with women and the relationship with partners; and (3) practice, that captured midwifery presence, care across the childbirth continuum and practice that empowers women. Research and theoretical sources support the concept that being 'with woman' is a fundamental construct of midwifery practice as evident within the profession's philosophy. Findings suggest that the concept of midwives being 'with woman' is a dynamic and developing construct. The philosophy of being 'with woman' acts as an anchoring force to guide, inform and identify midwifery practice in the context of the rapidly changing modern maternity care landscapes. Gaps in knowledge and recommendations for further research are made. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

Cipryan, Lukas; Tschakert, Gerhard; Hofmann, Peter

2017-01-01

The purpose of the presented study was to compare acute and post-exercise differences in cardiorespiratory, metabolic, cardiac autonomic, inflammatory and muscle damage responses to high-intensity interval exercise (HIIT) between endurance and sprint athletes. The study group consisted of sixteen highly-trained males (age 22.1 ± 2.5 years) participating in endurance (n = 8) or sprint (n = 8) sporting events. All the participants underwent three exercise sessions: short HIIT (work interval duration 30s), long HIIT (3min) and constant load exercise (CE). The exercise interventions were matched for mean power, total time and in case of HIIT interventions also for work-to-relief ratio. The acute cardiorespiratory (HR, V̇O2, RER) and metabolic (lactate) variables as well as the post-exercise changes (up to 3 h) in the heart rate variability, inflammation (interleukin-6, leucocytes) and muscle damage (creatine kinase, myoglobin) were monitored. Endurance athletes performed exercise interventions with moderately (CE) or largely (both HIIT modes) higher mean V̇O2. These differences were trivial/small when V̇O2 was expressed as a percentage of V̇O2max. Moderately to largely lower RER and lactate values were found in endurance athletes. Markers of cardiac autonomic regulation, inflammation and muscle damage did not reveal any considerable differences between endurance and sprint athletes. In conclusions, endurance athletes were able to perform both HIIT formats with increased reliance on aerobic metabolic pathways although exercise intensity was identical in relative terms for all the participants. However, other markers of the acute and early post-exercise physiological response to these HIIT interventions indicated similarities between endurance and sprint athletes. Key points The manner in which each training background (endurance vs. sprint) influences the response to HIIT is not well known. Despite the identical exercise intensity in relative terms, endurance

Down syndrome (DS) and Fragile X syndrome (FXS) are the major genetic causes of intellectual disabilities. Here, we present a case of a 32-year-old woman with the diagnosis of both FXS and DS. She is the daughter of a 47-year-old pre-mutation woman who also has three sons with FXS. Cytogenetic testing detected the presence of a complete trisomy 21. A combination of PCR and Southern blot analysis was utilized to document the presence of the FMR1 full mutation. The patient has physical characteristics and behavioural disturbances typical of both FXS and DS, which were confirmed by molecular testing. Her treatment plan included a trial of sertraline because of the severity of her shyness and lack of language. She had an excellent response to sertraline with improvement in shyness and social interactions, particularly with family members. In this study, we report the case of a woman with both FXS and DS, which is the fifth case of FXS and DS in the world's literature. The patient is from Ricaurte, a small town in Colombia, South America, where there is the world's highest prevalence for FXS. © 2016 John Wiley & Sons Ltd.

Objective: To evaluate the incidence and the MRI and scintigraphic appearance of acetabular stress (fatigue) fractures in military endurance athletes and recruits. Design and patients: One hundred and seventy-eight active duty military endurance trainees with a history of activity-related hip pain were evaluated by both MRI and bone scan over a 2-year period. Patients in the study ranged in age from 17 to 45 years. They had hip pain related to activity and had plain radiographs of the hip and pelvis that were interpreted as normal or equivocal. The study was originally designed to evaluate the MRI and scintigraphic appearance of femoral neck stress fractures. Patients had scintigraphy and a limited MRI examination (coronal imaging only) within 48 h of the bone scan. Twelve patients demonstrated imaging findings compatible with acetabular stress fractures. Results: Stress fractures are common in endurance athletes and in military populations; however, stress fracture of the acetabulum is uncommon. Twelve of 178 patients (6.7%) in our study had imaging findings consistent with acetabular stress fractures. Two patterns were identified. Seven of the 12 (58%) patients had acetabular roof stress fractures. In this group, two cases of bilateral acetabular roof stress fractures were identified, one with a synchronous tensile sided femoral neck stress fracture. The remaining five of 12 (42%) patients had anterior column stress fractures, rarely occurring in isolation, and almost always occurring with inferior pubic ramus stress fracture (4 of 5, or 80%). One case of bilateral anterior column stress fractures was identified without additional sites of injury. Conclusions: Stress fractures are commonplace in military populations, especially endurance trainees. Acetabular stress fractures are rare and therefore unrecognized, but do occur and may be a cause for activity-related hip pain in a small percentage of military endurance athletes and recruits.

Endurance training enhances mitochondrial oxidative capacity, but its effect on mitochondria functioning is poorly understood. In the present study, the influence of an 8-week endurance training on the bioenergetic functioning of rat skeletal muscle mitochondria under different assay temperatures (25, 35, and 42 °C) was investigated. The study was performed on 24 adult 4-month-old male Wistar rats, which were randomly assigned to either a treadmill training group (n = 12) or a sedentary control group (n = 12). In skeletal muscles, endurance training stimulated mitochondrial biogenesis and oxidative capacity. In isolated mitochondria, endurance training increased the phosphorylation rate and elevated levels of coenzyme Q. Moreover, a decrease in mitochondrial uncoupling, including uncoupling protein-mediated proton leak, was observed after training, which could explain the increased reactive oxygen species production (in nonphosphorylating mitochondria) and enhanced oxidative phosphorylation efficiency. At all studied temperatures, endurance training significantly augmented H2O2 production (and coenzyme Q reduction level) in nonphosphorylating mitochondria and decreased H2O2 production (and coenzyme Q reduction level) in phosphorylating mitochondria. Endurance training magnified the hyperthermia-induced increase in oxidative capacity and attenuated the hyperthermia-induced decline in oxidative phosphorylation efficiency and reactive oxygen species formation of nonphosphorylating mitochondria via proton leak enhancement. Thus, endurance training induces both quantitative and qualitative changes in muscle mitochondria that are important for cell signaling as well as for maintaining muscle energy homeostasis, especially at high temperatures.

Carbohydrate Dependence During Prolonged, Intense Endurance Exercise.

Science.gov (United States)

Hawley, John A; Leckey, Jill J

2015-11-01

A major goal of training to improve the performance of prolonged, continuous, endurance events lasting up to 3 h is to promote a range of physiological and metabolic adaptations that permit an athlete to work at both higher absolute and relative power outputs/speeds and delay the onset of fatigue (i.e., a decline in exercise intensity). To meet these goals, competitive endurance athletes undertake a prodigious volume of training, with a large proportion performed at intensities that are close to or faster than race pace and highly dependent on carbohydrate (CHO)-based fuels to sustain rates of muscle energy production [i.e., match rates of adenosine triphosphate (ATP) hydrolysis with rates of resynthesis]. Consequently, to sustain muscle energy reserves and meet the daily demands of training sessions, competitive athletes freely select CHO-rich diets. Despite renewed interest in high-fat, low-CHO diets for endurance sport, fat-rich diets do not improve training capacity or performance, but directly impair rates of muscle glycogenolysis and energy flux, limiting high-intensity ATP production. When highly trained athletes compete in endurance events lasting up to 3 h, CHO-, not fat-based fuels are the predominant fuel for the working muscles and CHO, not fat, availability becomes rate limiting for performance.

Nutrition for endurance sports: marathon, triathlon, and road cycling.

Science.gov (United States)

Jeukendrup, Asker E

2011-01-01

Endurance sports are increasing in popularity and athletes at all levels are looking for ways to optimize their performance by training and nutrition. For endurance exercise lasting 30 min or more, the most likely contributors to fatigue are dehydration and carbohydrate depletion, whereas gastrointestinal problems, hyperthermia, and hyponatraemia can reduce endurance exercise performance and are potentially health threatening, especially in longer events (>4 h). Although high muscle glycogen concentrations at the start may be beneficial for endurance exercise, this does not necessarily have to be achieved by the traditional supercompensation protocol. An individualized nutritional strategy can be developed that aims to deliver carbohydrate to the working muscle at a rate that is dependent on the absolute exercise intensity as well as the duration of the event. Endurance athletes should attempt to minimize dehydration and limit body mass losses through sweating to 2-3% of body mass. Gastrointestinal problems occur frequently, especially in long-distance races. Problems seem to be highly individual and perhaps genetically determined but may also be related to the intake of highly concentrated carbohydrate solutions, hyperosmotic drinks, as well as the intake of fibre, fat, and protein. Hyponatraemia has occasionally been reported, especially among slower competitors with very high intakes of water or other low sodium drinks. Here I provide a comprehensive overview of recent research findings and suggest several new guidelines for the endurance athlete on the basis of this. These guidelines are more detailed and allow a more individualized approach.

Mice from four lines bred for high voluntary wheel activity run approximately 3-fold more revolutions per day and have elevated maximal oxygen consumption during forced treadmill exercise, as compared with four unselected control (C) lines. We hypothesized that these high runner (HR) lines would have greater treadmill endurance-running capacity. Ninety-six mice from generation 49 were familiarized with running on a motorized treadmill for 3 days. On days 4 and 5, mice were given an incremental speed test (starting at 20 m min(-1), increased 1.5 m min(-1) every 2 min) and endurance was measured as the total time or distance run to exhaustion. Blood samples were taken to measure glucose and lactate concentrations at rest during the photophase, during peak nightly wheel running, and immediately following the second endurance test. Individual differences in endurance time were highly repeatable between days (r=0.79), and mice tended to run longer on the second day (paired t-test, Pwheel running and treadmill endurance differed between the sexes, reinforcing previous studies that indicate sex-specific responses to selective breeding. HR mice appear to have a higher endurance capacity than reported in the literature for inbred strains of mice or transgenics intended to enhance endurance.

To explore whether high-level endurance training in early age has an influence on the arterial wall properties in young women. Forty-seven athletes (ATH) and 52 controls (CTR), all 17-25 years of age, were further divided into runners (RUN), whole-body endurance athletes (WBA), sedentary controls (SC) and normally active controls (AC). Two-dimensional ultrasound scanning of the carotid arteries was conducted to determine local common carotid artery (CCA) geometry and wall distensibility. Pulse waves were recorded with a tonometer to determine regional pulse wave velocity (PWV) and pulse pressure waveform. Carotid-radial PWV was lower in WBA than in RUN (P sedentary lifestyle. On the other hand, our data suggest that long-term endurance training is associated with potentially favourable peripheral artery adaptation, especially in sports where upper body work is added. This adaptation, if persisting later in life, could contribute to lower cardiovascular risk. © 2018 Scandinavian Physiological Society. Published by John Wiley & Sons Ltd.

Cylindroma is a benign skin adnexal tumour with apocrine and trichoepitheliomatous differentiation that is rarely seen in the breast. Here, we report a case of cylindroma in the subareolar region of the left breast in a 72-year-old woman who presented with a palpable mass. Ultrasound and mammographic reports of the lesion were considered probably malignant. An ultrasound-guided core needle biopsy was performed and the patient underwent wide local excision with axillary lymph nodes biopsy. Immunohistochemistry and histopathological studies confirmed cylindroma with fibrocystic changes in uninvolved parenchyma.

Passion and Pacing in Endurance Performance.

Schiphof-Godart, Lieke; Hettinga, Florentina J

2017-01-01

Endurance sports are booming, with sports passionates of varying skills and expertise battering city streets and back roads on their weekly or daily exercise rounds. The investments required for performing in endurance exercise are nevertheless considerable, and passion for their sport might explain the efforts endurance athletes are willing to make. Passion may be defined as a strong motivational force and as such might be related to the neurophysiological basis underlying the drive to exercise. A complex relationship between the brain and other systems is responsible for athletes' exercise behavior and thus performance in sports. We anticipate important consequences of athletes' short term choices, for example concerning risk taking actions, on long term outcomes, such as injuries, overtraining and burnout. We propose to consider athletes' type of passion, in combination with neurophysiological parameters, as an explanatory factor inunderstanding the apparent disparity in the regulation of exercise intensity during endurance sports. Previous research has demonstrated that athletes can be passionate toward their sport in either a harmonious or an obsessive way. Although both lead to considerable investments and therefore often to successful performances, obsessive passion may affect athlete well-being and performance on the long run, due to the corresponding inflexible exercise behavior. In this perspective we will thus examine the influence of passion in sport on athletes' short term and long term decision-making and exercise behavior, in particular related to the regulation of exercise intensity, and discuss the expected long term effects of both types of passion for sport.

Post-menopausal women are at significant risk for coronary artery disease, have increased rates of depression compared to their male counterparts, and often present atypically with coronary insufficiency. The symptoms of depression and coronary ischemia overlap greatly. Complaints like fatigue, body aches, and sleep disturbance reported by a depressed elderly woman may be cardiac related and need to be investigated seriously without physician bias. To ensure that clinicians are cautious when evaluating older women with a history of depression who are presenting with atypical complaints. A 61-year-old woman with history of depression presented to the Emergency Department with multiple complaints atypical for acute coronary syndrome. She had an immediate electrocardiogram and troponin-T Biosite point-of-care test (Biosite Incorporated, San Diego, CA) performed, which were positive for cardiac ischemia and myocardial infarction. The patient underwent immediate cardiac catheterization, which revealed occlusion of the mid left circumflex. After aspiration of thrombus and balloon dilatation of the site, a bare metal stent was deployed, restoring excellent flow. The patient did well medically but her depression worsened after the procedure and continues despite psychiatric intervention. For years there have been gender differences in medical treatment of coronary artery disease, and often women's complaints are not investigated aggressively. Post-menopausal women are at great risk for cardiac ischemia and depression, and their symptoms, which are often atypical, may not be diagnosed as anginal equivalents. In addition, depression is an independent risk factor for cardiovascular disease and, if it occurs after myocardial infarction, may lead to poor quality of life and increased morbidity and mortality. Patients who have had a coronary event must be thoroughly evaluated for signs of depression and receive the necessary treatment. Published by Elsevier Inc.

Weight-bearing exercise has been recognized widely to be beneficial for long-term bone health. However inherent differences in bone-loading characteristics and energy expenditure during participation in endurance sports place many endurance athletes at a relative disadvantage with regard to bone health compared with other athletes. Adolescents and adults who participate in endurance sports, such as running, and non-weight-bearing sports, such as biking and swimming, often have lower bone mineral density (BMD) than athletes participating in ball and power sports, and sometimes their BMD is lower than their inactive peers. Low BMD increases the risk of stress and fragility fractures, both while an athlete is actively competing and later in life. This article reviews the variable effects of distance running, cycling, swimming, and triathlons on bone health; the evaluation of stress and fragility fractures; and the diagnosis, management, and prevention of low BMD in endurance athletes.

Menopause is a sign of aging in the woman. Loss of ovarian function induces a reduction in resting metabolic rate, physical energy expenditure, fat-free mass and abdominal adipose tissue accumulation. Location of adipose tissue deposit in abdominal region plays an important role in occurrence of hyperlipidemia, diabetes, hypertension and atherosclerosis. Although regular participation in physical exercise have been suggested to improve adiposity and body flexibility which are important health related components of physical fitness, few published studies are available on the effect of exercise on Nigerian menopausal women. This study investigated effects of a twelve-week endurance exercise program (EEP) on central and abdominal obesity as well as flexibility of perimenopausal and postmenopausal Nigerian women. The study employed a pretest- posttest control group design comprising a sample of 175 apparently healthy, literate, sedentary women within age range 40-59 years. They were workers in state and federal establishments in Ibadan North Local Government Area of Oyo State, Nigeria. Based on history of their last menstrual period, women with regular or irregular menstrual cycle status were allocated into perimenopausal group and those who no longer menstruated into postmenopausal group. A table of random numbers was used for further allocation into perimenopausal exercise group (PEMEG, 45), postmenopausal exercise group (POMEG, 45) perimenopausal control group (PEMCG, 42) and postmenopausal control group (POMCG, 43). Waist Hip Ratio (WHR), Body Mass Index (BMI) as well as Hip and Trunk Flexibility (HTF) were evaluated at baseline and 4weekly intervals until end of 12th week. EEP consisted of a 10-station circuit of cardiovascular endurance, flexibility, coordination, abdominal and pelvic floor muscle exercises. Data were analyzed using descriptive and inferential statistics. Mean age of participants was 52.3±4.1 years, 95% C.I (51.64-52.88) years. Significant

Olanzapine had been reported to be effective in the control of tics in a few adult female patients who had a short follow-up period. The author reports the successful outcome of long-term olanzapine treatment in an adult woman with severe Tourette syndrome. A 33-year-old woman who had severe motor and vocal tics (Modified Rush Videotape Rating Scale: 17/20) showed an excellent response to olanzapine 10 mg/day within 2 months. Her tic symptoms were well controlled with gradual reduction of her dose of olanzapine to 2.5 mg/day during the following 8 years. She was symptom-free without medications in the past 2 years. In addition, she had a normal menstrual cycle and became pregnant during the period of olanzapine treatment. Olanzapine may be the drug of first choice for treating severe Tourette syndrome in pubescent female adolescents and young women who wish to have children.

Abscessed Uterine and Extrauterine Adenomyomas with Uterus-Like Features in a 56-Year-Old Woman

Full Text Available Adenomyosis, also known as endometriosis interna, is the presence of endometrial glands and stroma within the myometrium. Its localised form is called adenomyoma and mimics a leiomyoma. Rarely, adenomyomas are located outside the uterus and some of them form uterus-like masses with a thick muscle wall and an endometrium-lined central cavity. They are generally located in the ovary or broad ligament, and, although they are closely related to endometriosis, their pathogenetic mechanisms are different from each other. Müllerian duct fusion defect and subcoelomic mesenchyme transformation theory are two possible pathogenetic mechanisms for this rare entity. Here we report abscessed uterine and extrauterine adenomyomas forming uterus-like masses in the left and right broad ligament and an ectopic adrenal tissue in the left paraovarian region in a 56-year-old woman. Although there is a reported abscessed adenomyosis in the literature, this is the first abscessed extrauterine uterus-like masses with synchronous pelvic pathologies like endometriosis, leiomyomas, adenomyosis, an endometrial polyp, an endocervical polyp, and an ectopic adrenal tissue. This benign lesion gives the impression of leiomyoma, a uterine malformation, or even malignancy preoperatively. Frozen section helps in differential diagnosis.

Full Text Available We aimed to compare site-specific bone mineral densities (BMDs between adolescent endurance runners and sprinters and examine the relationship of fat-free mass (FFM and nutrient intake on BMD. In this cross-sectional study, 37 adolescent female endurance runners and sprinters (16.1 ± 0.8 years were recruited. BMD and FFM were assessed by dual-energy X-ray absorptiometry. Nutrient intake and menstrual state were evaluated by questionnaires. After adjusting for covariates, spine and total bone less head (TBLH BMDs were significantly higher in sprinters than endurance runners (TBLH, 1.02 ± 0.05 vs. 0.98 ± 0.06 g/cm2; spine, 0.99 ± 0.06 vs. 0.94 ± 0.06 g/cm2; p < 0.05. There was no significant difference between groups in other sites. The rate of menstrual abnormality was higher in endurance runners compared with sprinters (56.3% vs. 23.8%; p < 0.05. FFM was a significant covariate for BMD on all sites except the spine (p < 0.05. Dietary intake of vitamin D was identified as a significant covariate only for pelvic BMD (p < 0.05. The BMDs of different sites among endurance runners and sprinters were strongly related to FFM. However, the association of FFM with spine BMD cannot be explained by FFM alone. Other factors, including nutrition and/or mechanical loading, may affect the spine BMD.

Although regular sports activities decrease the risk of venous thromboembolism (VTE), VTE cases have been observed among professional and amateur athletes practicing various disciplines. The authors describe a case of a 25-year-old-woman in whom calf pain, as popliteal vein thrombosis manifestation--preceding pulmonary embolism, occurred after she took up spinning, a popular form of indoor cycling. There was no history of leg injury. In hemostasis work up, factor V Leiden mutation and acquired low antithrombin activity-related to oral contraceptives use, were found. Strenuous exercise in an untrained woman might augment prothrombotic hemostasis profile. Vigorous cycling in standing position in the last phase of spinning, seems to be most unfavorable for patients with high VTE risk.

Acute and enduring adverse effects of psilocybin have been reported anecdotally, but have not been well characterized. For this study, 1993 individuals (mean age 30 yrs; 78% male) completed an online survey about their single most psychologically difficult or challenging experience (worst "bad trip") after consuming psilocybin mushrooms. Thirty-nine percent rated it among the top five most challenging experiences of his/her lifetime. Eleven percent put self or others at risk of physical harm; factors increasing the likelihood of risk included estimated dose, duration and difficulty of the experience, and absence of physical comfort and social support. Of the respondents, 2.6% behaved in a physically aggressive or violent manner and 2.7% received medical help. Of those whose experience occurred >1 year before, 7.6% sought treatment for enduring psychological symptoms. Three cases appeared associated with onset of enduring psychotic symptoms and three cases with attempted suicide. Multiple regression analysis showed degree of difficulty was positively associated, and duration was negatively associated, with enduring increases in well-being. Difficulty of experience was positively associated with dose. Despite difficulties, 84% endorsed benefiting from the experience. The incidence of risky behavior or enduring psychological distress is extremely low when psilocybin is given in laboratory studies to screened, prepared, and supported participants. © The Author(s) 2016.

Leone, James E

2009-05-01

We describe a 23-year-old woman with muscle dysmorphia symptomatology and extreme drive for muscularity. In addition to structured case study interviews, 3 questionnaires and a series of semistructured interview questions were administered for elaboration on key issues. The case studies allowed for triangulation of data garnered from the questionnaires. Responses revealed high scores for drive for muscularity, moderate scores for the Adonis complex, and high scores for symptoms of muscle dysmorphia. Muscle dysmorphia and drive for muscularity are more prevalent in men; however, unique cases such as this need to be further explored both empirically and theoretically. Cross-cultural references are needed to assess the overall impact of global social influences. Instruments measuring muscle dysmorphia need to be devised and validated for women as well as men. The strength and conditioning professional needs to be both aware and vigilant in helping people affected with psychosomatic disorders such as muscle dysmorphia or exercise addiction.

Full Text Available Abstract The HELLP syndrome (haemolysis, elevated liver blood tests and low platelets is a serious complication in pregnancy characterized by haemolysis, elevated liver enzymes and low platelet count occurring in 0.5 to 0.9% of all pregnancies and in 10–20% of cases with severe preeclampsia. Hepatic capsular rupture is a rare yet dramatic complication of HELLP syndrome. The majority of cases occur in multiparous women over the age of 30. Classically it presents with acute onset right upper quadrant pain in the presence of constitutional symptoms such as vomiting and pyrexia. However, symptoms and signs are usually non specific. Spontaneous hepatic rupture can be preceded by signs of hypovolaemic shock; yet the diagnosis is infrequently made prior to emergent laparotomy. We present the case of a 35 year old nulliparous woman with a second trimester gestational hepatic rupture associated with HELLP syndrome. We briefly discuss the aetiology, diagnostic difficulties and treatment options associated with this rare presentation.

Endurance training at altitude.

Science.gov (United States)

Saunders, Philo U; Pyne, David B; Gore, Christopher J

2009-01-01

Since the 1968 Olympic Games when the effects of altitude on endurance performance became evident, moderate altitude training ( approximately 2000 to 3000 m) has become popular to improve competition performance both at altitude and sea level. When endurance athletes are exposed acutely to moderate altitude, a number of physiological responses occur that can comprise performance at altitude; these include increased ventilation, increased heart rate, decreased stroke volume, reduced plasma volume, and lower maximal aerobic power ((.)Vo(2max)) by approximately 15% to 20%. Over a period of several weeks, one primary acclimatization response is an increase in the volume of red blood cells and consequently of (.)Vo(2max). Altitudes > approximately 2000 m for >3 weeks and adequate iron stores are required to elicit these responses. However, the primacy of more red blood cells for superior sea-level performance is not clear-cut since the best endurance athletes in the world, from Ethiopia (approximately 2000 to 3000 m), have only marginally elevated hemoglobin concentrations. The substantial reduction in (.)Vo(2max) of athletes at moderate altitude implies that their training should include adequate short-duration (approximately 1 to 2 min), high-intensity efforts with long recoveries to avoid a reduction in race-specific fitness. At the elite level, athlete performance is not dependent solely on (.)Vo(2max), and the "smallest worthwhile change" in performance for improving race results is as little as 0.5%. Consequently, contemporary statistical approaches that utilize the concept of the smallest worthwhile change are likely to be more appropriate than conventional statistical methods when attempting to understand the potential benefits and mechanisms of altitude training.

A combination of endurance and strength training is generally used to seek further health benefits or enhanced physical performance in older adults compared with either of the training modes alone. The mean change within a training group, however, may conceal a wide range of individual differences in the responses. The purpose, therefore, was to examine the individual trainability of aerobic capacity and maximal strength, when endurance and strength training are performed separately or concurrently. For this study, 175 previously untrained volunteers, 89 men and 86 women between the ages of 40 and 67 yr, completed a 21-wk period of either strength training (S) twice a week, endurance training (E) twice a week, combined training (ES) four times per week, or served as controls. Training adaptations were quantified as peak oxygen uptake (VO2peak) in a bicycle ergometer test to exhaustion and maximal isometric bilateral leg extension force (MVC) in a dynamometer. A large range in training responses, similar to endurance or strength training alone, was also observed with combined endurance and strength training in both ΔVO2peak (from -8% to 42%) and ΔMVC (from -12% to 87%). There were no significant correlations between the training responses in VO2peak and MVC in the E, S, or especially in the ES group, suggesting that the same subjects did not systematically increase both aerobic capacity and maximal strength. The goal of combined endurance and strength training--increasing both aerobic capacity and maximal strength simultaneously--was only achieved by some of the older subjects. New means are needed to personalize endurance, strength, and especially combined endurance and strength training programs for optimal individual adaptations.

2011-01-01

Full Text Available Distal biceps tendon rupture is a relatively uncommon occurrence in the general female population, and to our knowledge, has not been reported in association with a supinator muscle tear. We report a case of 51-year-old woman who experienced sharp pain in her forearm and elbow after lifting a heavy object. History and physical examination raised suspicion for a distal biceps tendon rupture. MRI imaging determined a combined distal biceps tendon tear with a supinator muscle tear with subsequent confirmation at surgery. Surgical repair was performed for the distal biceps tendon only through a single incision approach using the Endobutton technique.

Os ácidos graxos plasmáticos encontram-se disponíveis para as fibras musculares sob a forma de ácidos graxos associados à albumina ou agregados à molécula de triacilglicerol (TAG encontrada nas lipoproteínas. Entretanto, além dessas fontes plasmáticas, a hidrólise do TAG encontrado no músculo também pode contribuir com a oferta de ácidos graxos durante o exercício de endurance. O objetivo do presente trabalho foi realizar uma extensa revisão da literatura sobre a importância do TAG intramuscular como substrato energético. A revisão da literatura sugere que a contribuição dos estoques endógenos de TAG durante a realização do exercício de endurance é bastante relevante. Além disso, pode-se concluir que uma adaptação induzida pelo treinamento de endurance é o aumento dos estoques intramusculares de TAG. Após o treinamento de endurance, também é observado aumento na capacidade de utilização desses estoques. Apesar de parecer importante, a contribuição do TAG intramuscular ainda é motivo de controvérsia na literatura. Essa discrepância de resultados está relacionada às metodologias empregadas para estimar a sua oxidação no exercício.

Full Text Available Abstract Background Shoulder muscle fatigue has been proposed as a possible link to explain the association between repetitive arm use and the development of rotator cuff disorders. To our knowledge, no standardized clinical endurance protocol has been developed to evaluate the effects of muscle fatigue on shoulder function. Such a test could improve clinical examination of individuals with shoulder disorders. Therefore, the purpose of this study was to establish a reliable protocol for objective assessment of shoulder muscle endurance. Methods An endurance protocol was developed on a stationary dynamometer (Biodex System 3. The endurance protocol was performed in isotonic mode with the resistance set at 50% of each subject's peak torque as measured for shoulder external (ER and internal rotation (IR. Each subject performed 60 continuous repetitions of IR/ER rotation. The endurance protocol was performed by 36 healthy individuals on two separate occasions at least two days apart. Maximal isometric shoulder strength tests were performed before and after the fatigue protocol to evaluate the effects of the endurance protocol and its reliability. Paired t-tests were used to evaluate the reduction in shoulder strength due to the protocol, while intraclass correlation coefficients (ICC and minimal detectable change (MDC were used to evaluate its reliability. Results Maximal isometric strength was significantly decreased after the endurance protocol (P 0.84. Conclusions Changes in muscular performance observed during and after the muscular endurance protocol suggests that the protocol did result in muscular fatigue. Furthermore, this study established that the resultant effects of fatigue of the proposed isotonic protocol were reproducible over time. The protocol was performed without difficulty by all volunteers and took less than 10 minutes to perform, suggesting that it might be feasible for clinical practice. This protocol could be used to induce

Bochdalek hernia presentation in adulthood is rare. The presentation in newborns is the most common, manifesting with data from respiratory failure secondary to pulmonary hypoplasia, requiring urgent surgical intervention with high morbidity and mortality. We present the case of a 33 year old woman admitted in the emergency room with severe abdominal pain in the left upper quadrant and disnea. After physical examination and laboratory test we diagnose mild acute pancreatitis. The patient haven't colelitiasis by ulstrasound or any risk factor for pancreatitis. Initially she received medical treatment and was discharged after one week. After four weeks she presented the same symptoms in two different occasions, with severe and mild pancreatitis respectively. A computed tomography report a left posterolateral diafragmatic hernia. In spite of the rare association of pancreatitis and Bochdalek hernia, we realized it as the etiology until the second event and planned his surgery. We made a posterolateral torachotomy and diafragmatic plasty with a politetrafluoroetileno mesh and after a 6 months follow up she has coursed asymptomatic. The high rate of complications in this type of hernia requires us to perform surgical treatment as the hernia is detected. In this case it is prudent medical treatment prior to surgical correction despite this being the origin of the pancreatitis, because the systemic inflammatory response added by the surgical act could result in a higher rate of complications if not performed at the appropriate time. There is no precise rule to determine the type of approach of choice in this type of hernia which thoracotomy or laparotomy may be used. Bochdalek hernia is a rare find in adults who require treatment immediately after diagnosis because of the high risk of complications. When presented with data from pancreatitis is recommended to complete the medical treatment of pancreatitis before surgery to obtain the best results, unless it exist another

The aim of this study was to compare muscle mechanical properties (using tensiomyography-TMG) and jumping performance of endurance and power athletes and to quantify the associations between TMG parameters and jumping performance indices. Forty-one high-level track and field athletes from power (n = 22; mean ± SD age, height, and weight were 27.2 ± 3.6 years; 180.2 ± 5.4 cm; and 79.4 ± 8.6 kg, respectively) and endurance (endurance runners and triathletes; n = 19; mean ± SD age, height, and weight were 27.1 ± 6.9 years; 169.6 ± 9.8 cm; 62.2 ± 13.1 kg, respectively) specialties had the mechanical properties of their rectus femoris (RF) and biceps femoris (BF) assessed by TMG. Muscle displacement (Dm), contraction time (Tc), and delay time (Td) were retained for analyses. Furthermore, they performed squat jumps (SJs), countermovement jumps (CMJs), and drop jumps to assess reactive strength index (RSI), using a contact platform. Comparisons between groups were performed using differences based on magnitudes, and associations were quantified by the Spearman's ρ correlation. Power athletes showed almost certain higher performance in all jumping performance indices when compared with endurance athletes (SJ = 44.9 ± 4.1 vs. 30.7 ± 6.8 cm; CMJ = 48.9 ± 4.5 vs. 33.6 ± 7.2 cm; RSI = 2.19 ± 0.58 vs. 0.84 ± 0.39, for power and endurance athletes, mean ± SD, respectively; 00/00/100, almost certain, p ≤ 0.05), along with better contractile indices reflected by lower Dm, Tc, and Td (Tc BF = 14.3 ± 2.3 vs. 19.4 ± 3.3 milliseconds; Dm BF = 1.67 ± 1.05 vs. 4.23 ± 1.75 mm; Td BF = 16.8 ± 1.6 vs. 19.6 ± 1.3 milliseconds; Tc RF = 18.3 ± 2.8 vs. 22.9 ± 4.0 milliseconds; Dm RF = 4.98 ± 3.71 vs. 8.88 ± 3.45 mm; Td RF = 17.5 ± 1.0 vs. 20.9 ± 1.6 milliseconds, for power and endurance athletes, mean ± SD, respectively; 00/00/100, almost certain, p ≤ 0.05). Moderate correlations (Spearman's ρ between -0.61 and -0.72) were found between TMG and jumping

Full Text Available Summary Introduction: Digital palpation and manometry are methods that can provide information regarding maximum voluntary contraction (MVC and endurance of the pelvic floor muscles (PFM, and a strong correlation between these variables can be expected. Objective: To investigate the correlation between MVC and endurance, measured by digital palpation and manometry. Method: Forty-two women, with mean age of 58.1 years (±10.2, and predominant symptoms of stress urinary incontinence (SUI, were included. Examination was firstly conducted by digital palpation and subsequently using a Peritron manometer. MVC was measured using a 0-5 score, based on the Oxford Grading Scale. Endurance was assessed based on the PERFECT scheme. Results: We found a significant positive correlation between the MVC measured by digital palpation and the peak manometric pressure (r=0.579, p<0.001, and between the measurements of the endurance by Peritron manometer and the PERFECT assessment scheme (r=0.559, P<0.001. Conclusion: Our results revealed a positive and significant correlation between the capacity and maintenance of PFM contraction using digital and manometer evaluations in women with predominant symptoms of SUI.

In people with COPD, dyspnea is the primary symptom limiting exercise tolerance. One approach to reducing dyspnea during exercise is through music listening. A constant speed endurance test reflects a high-intensity aerobic exercise training session, but whether listening to music affects endurance time is unknown. This study aimed to determine the effects of listening to music during a constant speed endurance test in COPD. Participants with COPD completed two endurance walk tests, one with and one without listening to self-selected music throughout the test. The primary outcome was the difference in endurance time between the two conditions. Heart rate, percutaneous oxygen saturation, dyspnea, and rate of perceived exertion were measured before and after each test. Nineteen participants (mean [SD]: age, 71 [8] years; FEV 1 , 47 [19] % predicted) completed the study. Endurance time was greater (1.10 [95% CI, 0.41-1.78] min) while listening to music (7.0 [3.1] min) than without (5.9 [2.6] min), and reduced end-test dyspnea (1.0 [95% CI, -2.80 to -1.80] units) (with music, 4.6 [1.7] units; vs without music, 5.6 [1.4] units, respectively). There was not a significant difference in heart rate, percutaneous oxygen saturation, or leg fatigue. There were no adverse events under either condition. In COPD, dyspnea was less while listening to music and was accompanied by an increased tolerance of high-intensity exercise demonstrated by greater endurance time. Practically, the effect was modest but may represent an aid for exercise training of these patients. Australian New Zealand Clinical Trials Registry; No. ACTRN12617001217392.

This article focuses exclusively on physical examination (PE) in the context of clinical medicine, that is, the interaction between a health care provider and patient. In essence, there is not only benefit (value) to PE but also that it will last (endure) for some time. Both "enduring" and "value" are explored in more depth with respect to the future integration of PE into the clinical assessment of a patient and how its value extends well beyond current diagnostic/cost-based metrics.

Being with woman: claiming midwifery space.

Science.gov (United States)

Hunter, Louise

2015-03-01

Being 'with woman' is characterised as presence, a spiritual concept which is nevertheless bound up with physical space. In this article, the work of the American philosopher Judith Butler is used to explore the interplay between space and relationships in midwifery practice. Butler argues that relationships based on mutual recognition and respect define the actions possible within physical space. In midwifery, being with woman creates a therapeutic space necessary for the wellbeing and empowerment of women and midwives alike.

Position of woman according to 19th century Montenegrin marital law

Directory of Open Access Journals (Sweden)

Kulauzov Maša

2013-01-01

Full Text Available Legal position of woman in 19th century Montenegrin marital law is examined in this paper. Provisions on entering into marriage, woman's marital infidelity, legal separation, dissolution of marriage and its legal effects as well as widow's property rights are scrutinized and critically analyzed. The author also indicates to rules of customary law regarding legal status of a married woman. Married woman had restricted legal capacity, as well as restricted property rights and no rights of succession. However, gender inequality common in patriarchal society such as Montenegrin in 19th century is particularly accentuated in case of marital infidelity. Only woman's adultery is punishable and regarded as a serious crime. Beside marital infidelity, lower position of woman is noticeable in all aspects of married life. Hence, legislative attempts to improve woman's legal status are emphasized in the article.

Endurance exercise after orange ingestion anaphylaxis

Full Text Available Endurance exercise after orange ingestion cause anaphylaxis which is food-dependent exercise-induced anaphylaxis (FDEIA which is a form of exercise-induced anaphylaxis. In this article, an individual develops symptoms such as flushing, itching, urticaria, angioedema, and wheezing after eating a food allergen and proceeds to exercise. Neither the food alone nor exercise alone is sufficient to induce a reaction. This case report describes a 36-year-old asthmatic male athlete who experienced nausea, vomiting, flushing, urticaria, and facial swelling while exercising in a gymnasium after eating oranges. Neither oranges alone nor exercise alone induced the reaction. Total avoidance of suspected food allergens would be ideal. Persons with FDEIA should keep at hand an emergency kit with antihistamines, injectable rapid action corticoids, and adrenaline.

The pregnant woman and the good Samaritan: can a woman have a duty to undergo a caesarean section?

Science.gov (United States)

Scott, R

2000-01-01

Although a pregnant woman can now refuse any medical treatment needed by the fetus, the Court of Appeal has acknowledged that ethical dilemmas remain, adverting to the inappropriateness of legal compulsion of presumed moral duties in this context. This leaves the impression of an uncomfortable split between the ethics and the law. The notion of a pregnant woman refusing medical treatment needed by the fetus is troubling and it helps little simply to assert that she has a legal right to do so. At the same time, the idea that a pregnant woman fails in her moral duty unless she accepts any recommended treatment or surgery--however great the burden--is also not without difficulty. This article seeks to find a way between these two somewhat polarized positions by arguing that, instead of being a question primarily about whether legally to enforce moral obligations, the 'maternal-fetal conflict' begins with previously unrecognized difficulties in determining when a woman's prima facie moral rights invoked in the treatment context should 'give way' to the interests of the fetus. This difficulty is mirrored within the law. Thus, how can we tell when a pregnant woman has the moral or legal duty to submit to a caesarean section? Seen in this way, the conflict is a problem which lies at the interface between moral and legal rights and duties, showing that there are important conceptual links between the ethics and the law. Against this background, this article explores the limits of a pregnant woman's right to bodily integrity by focusing upon the idea of her moral duty to aid the fetus through her body. Here we find difficulties in determining the existence and extent of this somewhat extraordinary duty. Such a duty is contrasted with both negative and positive duties toward others in the course of 'general conduct.' Attention to the social context of pregnancy and the refusal of treatment within this is also instructive. Overall, the purpose is to foster understanding and

Achieving excellence in track and field athletes requires specific mental skills. The aim of the present study was to compare the mental skills between elite sprint and endurance athletes. Forty elite athletes (age 20.55±2.22 years, body mass 74.8±7.9 kg, height 1.70±0.1 m) participated in the present study. The athletes were classified into two groups according to their genetic polymorphism to physical activity: Endurance group (allele I, N.=20) and power group (allele D, N.=20). The mental skills were assessed by means of Ottawa Mental Skill Assessment Tool-3 inventory (OMSAT-3: based in foundation mental skills, psychosomatic skills, and cognitive skills subscales) before the competition period. Furthermore, genetic data were also collected. Sprint and endurance runners were participating in Tunisian National championship. The results showed a significant difference between elite sprint and endurance runners in the foundation mental and psychosomatic skills subscales (all, Pstudy revealed that goal setting, commitment, stress reactions, fear control, imagery, competition planning and mental practice were significantly higher among the elite sprint runners compared to the endurance runners (all, Pstudy could confirm the widely acclaimed research assumption that mental skills, such as goal setting, commitment and mental practice, are the predictor variables of power performances, while endurance performances are associated with different mental skills components. Finally, the results may inform applied practitioners regarding the differences in mental skill demands between power and endurance athletes and the genetic predisposition of practitioners.

Addison's disease presenting with idiopathic intracranial hypertension in 24-year-old woman: a case report

Directory of Open Access Journals (Sweden)

Moore Peter

2010-02-01

Full Text Available Abstract Introduction Idiopathic intracranial hypertension can rarely be associated with an underlying endocrine disorder such as Cushing's syndrome, hyperthyroidism, or with administration of thyroxine or growth hormone. Though cases of idiopathic intracranial hypertension associated with Addison's disease in children have been reported, there is only one documented case report of this association in adults. We describe a case of an acute adrenal insufficiency precipitated by idiopathic intracranial hypertension in a Caucasian female. Case presentation A 24-year-old Caucasian woman was acutely unwell with a background of several months of generalised fatigue and intermittent headaches. She had unremarkable neurological and systemic examination with a normal computerised tomography and magnetic resonance imaging of the brain. Normal cerebrospinal fluid but increased opening pressure at lumbar puncture suggested intracranial hypertension. A flat short synacthen test and raised level of adrenocorticotrophic hormone were consistent with primary adrenal failure. Conclusion Addison's disease can remain unrecognised until precipitated by acute stress. This case suggests that idiopathic intracranial hypertension can rarely be associated with Addison's disease and present as an acute illness. Idiopathic intracranial hypertension is possibly related to an increase in the levels of arginine vasopressin peptide in serum and cerebrospinal fluid secondary to a glucocorticoid deficient state.

Patients with chronic neck pain show also respiratory dysfunctions. To investigate the effects of respiratory muscle endurance training (RMET) on chronic neck pain. In this pilot study (single-subject design: 3 baseline measurements, 4 measurements during RMET), 15 neck patients (49.3 ± 13.7 years; 13 females) conducted 20 sessions of home-based RMET using a SpiroTiger® (normocapnic hyperpnoea). Maximal voluntary ventilation (MVV), maximal inspiratory (Pimax) and expiratory (Pemax) pressure were measured before and after RMET. Neck flexor endurance, cervical and thoracic mobility, forward head posture, chest wall expansion and self-assessed neck disability [Neck Disability Index (NDI), Bournemouth questionnaire] were weekly assessed. Repeated measure ANOVA (Bonferroni correction) compared the first and last baseline and the last measurement after RMET. RMET significantly increased MVV (p= 0.025), Pimax (p= 0.001) and Pemax (pneck pain. The underlying mechanisms, including blood gas analyses, need further investigation in a randomized controlled study.

Previous studies in developing countries suggest that a husband plays an influential role in a woman's contraceptive use. The influence of a husband/partner's healthcare decision making power on a woman's intention to use contraceptives in Mozambique has not been studied. The present study examined this relationship using data from the 2011 Mozambique Demographic and Health Survey (DHS), which included a nationally representative sample of 7,022 women aged 15-49 years. The primary outcome of interest in the study was a woman's intention to use contraceptives. The primary exposure of interest was the person making decisions about a woman's healthcare, dichotomized as the husband/partner alone vs. the woman herself or jointly with her husband/partner. Several potential socio-demographic confounders were adjusted for in overall and stratified multivariable logistic regression models. Adjusted odds ratio (AOR) and the associated 95% confidence interval (CI) are reported. The mean age of the sample was 30.4 (95% CI: 30.1 - 30.7) years. Overall, a woman who reported her husband/partner usually made the decision about her healthcare was 19% less likely to report an intention to use contraceptives than a woman who reported that she herself or jointly with her husband/partner made the decision (AOR = 0.81, 95% CI 0.71- 0.92). In stratified analyses, the association remained statistically significant among rural women (AOR = 0.75, 95% CI: 0.65 - 0.87); among women with knowledge of modern contraceptive methods (AOR = 0.83, 95% CI: 0.73 - 0.95); and among women with three or more (AOR = 0.81, 95% CI: 0.68 - 0.97) and two or fewer (AOR = 0.79, 95% CI: 0.65 - 0.96) living children. A husband/partner's healthcare decision making power in the relationship had a significant negative effect on a Mozambican woman's intention to use contraceptives. These findings have implications for addressing the role of men in the design and implementation of successful family planning

Pregnant woman mode for absorbed fraction calculations

International Nuclear Information System (INIS)

Cloutier, R.J.; Snyder, W.S.; Watson, E.E.

1977-01-01

The most radiation-sensitive segment of our population is the developing fetus. Until recently, methods available for calculating the dose to the fetus were inadequate because a model for the pregnant woman was not available. Instead, the Snyder and Fisher model of Reference Man, which includes a uterus, was frequently used to calculate absorbed fractions when the source was in various organs of the body and the nongravid uterus was the target. These values would be representative of the dose to the embryo during the early stages of pregnancy. Unfortunately, Reference Man is considerable larger than Reference Woman. The authors recently reported on the design of a Reference Woman phantom that has dimensions quite similar to the ICRP Reference Woman. This phantom was suitable for calculating the dose to the embryo during early stages of pregnancy (0 to 3 mo.), but was not suitable for the later stages of pregnancy because of the changing shape of the mother and the displacement of several abdominal organs brought about by the growth of the uterus and fetus. The models of Reference Woman that were subsequently developed for each month of pregnancy are described. The models take into account the growth of the uterus and fetus and the repositioning of the various abdominal organs. These models have been used to calculate absorbed fractions for the fetus as a target and the gastrointestinal tract as a source of radiation for twelve photon energies ranging from 10 keV to 4 MeV

Woman in Roman law: Subject or object of the law?

Directory of Open Access Journals (Sweden)

Bogunović Mirjana

2012-01-01

Full Text Available In Rome, legal status of woman and her factual possibilities of impact on public life were in serious discrepancy. General attitude of the legal status of woman in time of Romans is best shown by Papinian, 'In many provisions of our law, the position of woman is worse than of man (D.9.1.5.'. Every free Roman woman was considered a subject of law, according to classical Roman law. Nevertheless, there were extensive legislations that limited her legal and business capacity. Naturally, woman did not have legal personality in all periods of Roman state and her legal status was adjusted to the factual changes that had occurred in Roman society. What makes her position specific in Rome is progressive social role that did not exist in Greek-Asian world. From these previously mentioned views, which were confronting, it is possible to draw some doubts. Was woman really on the margins of political happenings, or was she an actual actor, even initiator, of some political events?.

We report a case of a woman who was incidentally diagnosed with acromegaly after referral for prolonged post-partum amenorrhea. A 25-year-old woman, gravida 2 para 1, had a normal transvaginal delivery and breastfeeding had been discontinued more than a year after delivery. Thereafter, spontaneous menstruation did not restart and she underwent hormonal therapy. Subsequently, she was referred to our university hospital for prolonged amenorrhea. Hormonal examination revealed severe hypogonadotropic hypogonadism (luteinizing hormone 0.5 mIU/mL, follicle-stimulating hormone amenorrhea, which revealed mass lesions extending from the pituitary fossa to the suprasellar area with similar signal intensity as the gray matter. In addition, bitemporal hemianopsia was observed on campimetry. After further examination, the patient was diagnosed with acromegaly. © 2016 Japan Society of Obstetrics and Gynecology.

Western diets, which typically contain large amounts of energy-dense processed foods, together with a sedentary lifestyle are associated with increased cardiometabolic risk. We evaluated the long-term effects of consuming a low-calorie low-protein vegan diet or performing regular endurance exercise on cardiometabolic risk factors. In this cross-sectional study, cardiometabolic risk factors were evaluated in 21 sedentary subjects, who had been on a low-calorie low-protein raw vegan diet for 4.4 +/- 2.8 years, (mean age, 53.1 +/- 11 yrs), 21 body mass index (BMI)-matched endurance runners consuming Western diets, and 21 age- and gender-matched sedentary subjects, consuming Western diets. BMI was lower in the low-calorie low-protein vegan diet (21.3 +/- 3.1 kg/m(2)) and endurance runner (21.1 +/- 1.6 kg/m(2)) groups than in the sedentary Western diet group (26.5 +/- 2.7 kg/m(2)) (p vegan diet and runner groups than in the Western diet group (all p vegan diet group (104 +/- 15 and 62 +/- 11 mm Hg) than in BMI-matched endurance runners (122 +/- 13 and 72 +/- 9 mmHg) and Western diet group (132 +/- 14 and 79 +/- 8 mm Hg) (p vegan diet or regular endurance exercise training is associated with low cardiometabolic risk. Moreover, our data suggest that specific components of a low-calorie low-protein vegan diet provide additional beneficial effects on blood pressure.

Post-ERCP Emphysematous Cholecystitis in a Young Woman: A Rare and Potentially Fatal Complication

Directory of Open Access Journals (Sweden)

Roisin Stack

2017-01-01

Full Text Available A 45-year-old woman with suspected Functional Biliary Sphincter Disorder (FBSD developed Clostridium perfringens related emphysematous cholecystitis after ERCP. A low index of suspicion for emphysematous cholecystitis in this young, otherwise healthy woman led to a significant delay in making the correct diagnosis, and air in the gallbladder was wrongly attributed to a possible gallbladder perforation. ERCP is associated with significant risks, particularly in patients with FBSD, where diagnostic uncertainty renders the balance of risk versus benefit even more critical. Post-ERCP emphysematous cholecystitis secondary to Clostridium perfringens is a rare but potentially fatal complication.

Wonder Woman for a day: Affect, agency, and Amazons

Directory of Open Access Journals (Sweden)

Matt Yockey

2012-06-01

Full Text Available In this paper, I consider the ways in which the feminist utopian ethos of Wonder Woman, as defined by her creator, William Marston, has been used to actualize real-life social change. Specifically, I examine fan Andy Mangels's creation of Wonder Woman Day, a charity event held annually at a Portland, Oregon, comic book store to raise funds for local domestic violence programs. I look at how an affective bond with Wonder Woman informs and guides an affective attachment to one's local and national communities, actualizing the utopian promise of self, commodity icon, and America. These utopian iterations are primarily defined by a celebration of pluralism, and thus Wonder Woman is used to validate the inherent pluralism of the self in relation to society, an empowering strategy for all consumer-citizens.

Arrhythmogenic Right Ventricular Cardiomyopathy in an Endurance Athlete Presenting with Ventricular Tachycardia and Normal Right Ventricular Function.

2017-08-01

Arrhythmogenic right ventricular cardiomyopathy, a genetically inherited disease that results in fibrofatty replacement of normal cardiac myocytes, has been associated with sudden cardiac death in athletes. Long-term participation in endurance exercise hastens the development of both the arrhythmic and structural arrhythmogenic right ventricular cardiomyopathy phenotypes. We describe the unusual case of a 34-year-old, symptomatic, female endurance athlete who had arrhythmogenic right ventricular cardiomyopathy in the presence of a structurally normal right ventricle. Clinicians should be aware of this infrequent presentation when evaluating athletic patients who have ventricular arrhythmias and normal findings on cardiac imaging studies.

Exercising in the heat often results in an excessive increase in body core temperature, which can be detrimental to health and endurance performance. Research in recent years has shifted toward the optimum temperature at which drinks should be ingested. The ingestion of cold drinks can reduce body core temperature before exercise but less so during exercise. Temperature of drinks does not seem to have an effect on the rate of gastric emptying and intestinal absorption. Manipulating the specific heat capacity of a solution can further induce a greater heat sink. Ingestion of ice slurry exploits the additional energy required to convert the solution from ice to water (enthalpy of fusion). Body core temperature is occasionally observed to be higher at the point of exhaustion with the ingestion of ice slurry. There is growing evidence to suggest that ingesting ice slurry is an effective and practical strategy to prevent excessive rise of body core temperature and improve endurance performance. This information is especially important when only a fixed amount of fluid is allowed to be carried, often seen in some ultra-endurance events and military operations. Future studies should evaluate the efficacy of ice slurry in various exercise and environmental conditions. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available The left atrium is the most common location of myxomas, which are benign tumors. Only a few cases of myxomas in pregnancies have been reported. Our thorough medical literature search showed only 17 reported cases in the course of pregnancy. Myxomas during pregnancy and in the preterm period constitute a serious phenomenon that can mimic an early sign of a life-threatening pathology like severe mitral stenosis. We describe a 33-year-old woman, who presented with acute dyspnea to a gynecology center and was referred to our hospital for further evaluation of pulmonary embolism. Transthoracic echocardiography showed a huge left atrial myxoma, and computed tomography scan illustrated paradoxical pulmonary embolism in the left upper lung lobe via a large patent foramen ovale. The tumor required urgent cardiac surgery. In this article, we review causes of dyspnea in pregnancy and the cardiovascular effects of myxomas in pregnancy. We also describe the pathophysiological effects of cardiopulmonary bypass on the mother, fetus, and the feto-placental system during open-heart surgery. We performed a successful surgical resection of a myxoma in a pregnant woman. Given the rarity of such cases, individual multidisciplinary assessment and management strategies are essential.

Full Text Available Discourses on woman/space relations boomed in the 90s. The fundamental reason was to give support to the Feminist Movement. This trend which has had feeble effect on architectural design remained controversial. The comprehensive research expounded in this article which was based on an open-ended questionnaire that targeted at determining the gender roles at home, applied to female subjects who simulated the national demographics, clearly demonstrated that the home experience of an average Turkish woman basically consists of kitchens; the female who runs the house does not really have a place for herself at home. However she does not perceive her restrained, secondary role an issue worthy of struggling to change and she grants spaces for recreation and study to the male. The well-established civil laws conducive for equality has not changed this disturbing situation and do not seem to do so in the near future.

Comparability and repeatability of three commonly used methods for measuring endurance capacity.

Baxter-Gilbert, James; Mühlenhaupt, Max; Whiting, Martin J

2017-12-01

Measures of endurance (time to exhaustion) have been used to address a wide range of questions in ecomorphological and physiological research, as well as being used as a proxy for survival and fitness. Swimming, stationary (circular) track running, and treadmill running are all commonly used methods for measuring endurance. Despite the use of these methods across a broad range of taxa, how comparable these methods are to one another, and whether they are biologically relevant, is rarely examined. We used Australian water dragons (Intellagama lesueurii), a species that is morphologically adept at climbing, swimming, and running, to compare these three methods of endurance and examined if there is repeatability within and between trial methods. We found that time to exhaustion was not highly repeatable within a method, suggesting that single measures or a mean time to exhaustion across trials are not appropriate. Furthermore, we compared mean maximal endurance times among the three methods, and found that the two running methods (i.e., stationary track and treadmill) were similar, but swimming was distinctly different, resulting in lower mean maximal endurance times. Finally, an individual's endurance rank was not repeatable across methods, suggesting that the three endurance trial methods are not providing similar information about an individual's performance capacity. Overall, these results highlight the need to carefully match a measure of performance capacity with the study species and the research questions being asked so that the methods being used are behaviorally, ecologically, and physiologically relevant. © 2018 Wiley Periodicals, Inc.

There are strong genetic components to cardiorespiratory fitness and its response to exercise training. It would be useful to understand the differences in the genomic profile of highly trained endurance athletes of world class caliber and sedentary controls. An international consortium (GAMES) was established in order to compare elite endurance athletes and ethnicity-matched controls in a case-control study design. Genome-wide association studies were undertaken on two cohorts of elite endurance athletes and controls (GENATHLETE and Japanese endurance runners), from which a panel of 45 promising markers was identified. These markers were tested for replication in seven additional cohorts of endurance athletes and controls: from Australia, Ethiopia, Japan, Kenya, Poland, Russia and Spain. The study is based on a total of 1520 endurance athletes (835 who took part in endurance events in World Championships and/or Olympic Games) and 2760 controls. We hypothesized that world-class athletes are likely to be characterized by an even higher concentration of endurance performance alleles and we performed separate analyses on this subsample. The meta-analysis of all available studies revealed one statistically significant marker (rs558129 at GALNTL6 locus, p = 0.0002), even after correcting for multiple testing. As shown by the low heterogeneity index (I2 = 0), all eight cohorts showed the same direction of association with rs558129, even though p-values varied across the individual studies. In summary, this study did not identify a panel of genomic variants common to these elite endurance athlete groups. Since GAMES was underpowered to identify alleles with small effect sizes, some of the suggestive leads identified should be explored in expanded comparisons of world-class endurance athletes and sedentary controls and in tightly controlled exercise training studies. Such studies have the potential to illuminate the biology not only of world class endurance performance but

Endurance training in mild hypertension - effects on ambulatory blood pressure and neural circulatory control.

Science.gov (United States)

Narkiewicz; Somers

1997-10-01

This review examines the effects of a single bout of exercise and of endurance training on blood pressure in patients with hypertension. Possible autonomic mechanisms that mediate these changes in blood pressure are reviewed briefly. Blood pressure rises during exercise. During the second half hour after exercise blood pressure is lower. This p;ost-exercise reduction in blood pressure is associated with a decrease in muscle sympathetic nerve activity, an increase in baroreflex gain and a reduction in the level of blood pressure (set point) at which baroreflex activation occurs. The post-exercise fall in blood pressure appears to be limited to several hours and is not likely to explain any chronic reduction in blood pressure from endurance training. Endurance training elicits modest (approximately 4-5 mmHg) reductions in blood pressure. Because of the intrinsic variability of blood pressure, the decreases in blood pressure after endurance training is evident, especially when multiple measurements of blood pressure are obtained. Studies using 24 h blood pressure measurements suggest that, although endurance training lowers daytime blood pressure, blood pressure during sleep remains unchanged. The mechanism underlying the reduction in blood pressure in endurance training is not known. Although physical fitness is known to attenuate the sympathetic response to acute exercise, whether resting sympathetic drive is decreased with endurance training remains controversial. The slowing of heart rate that accompanies endurance training is also associated with an increase in variability of heart rate. The slower heart rate, increased variability of heart rate and lower blood pressure after endurance training are accompanied by an increase in baroreflex sensitivity. Even though the antihypertensive effect of endurance training is modest, the favourable effects of physical fitness on other risk factors for cardiovascular disease make exercise training an important approach in

Full Text Available The paper presents the case of the pregnant woman discovered at the medieval necropolis of “Preko Slatine” in Omoljica, a village near Pančevo. The necropolis is dated to the period of the 12th-13th century AD. It deals with a woman aged 25-30 (probably around 28 years old in the advanced stages of pregnancy, discovered in grave No. 13. This paper presents the possible conditions that led to the death of this woman, but also the problems faced by anthropologists when they attempt to resolve individual cases like this. In paleodemographic research, the mortality rate of pregnant woman is an important element of a population’s progress. Pregnant woman mortality is considered an adequate criterion for the social and sanitation conditions of a community and a sensitive indicator of health care and, sometimes, the skill level possessed by midwives or doctors.

A 34-year-old woman in the 22nd week of gestation presented with generalized pruritis and weight loss since the first trimester of pregnancy. Physical examination revealed cutaneous scratch lesions, jaundice, and hepatomegaly. Blood tests revealed cholestasis with elevated direct bilirubinemia. Auto-antibody and viral hepatitis tests were negative. Liver ultrasound was normal. The initial diagnosis was cholestasis of pregnancy. However despite treatment with ursodeoxycholic acid, the patient did not improve. Delivery was by cesarean section at the 26th week of pregnancy for obstetrical reasons. A new liver ultrasound showed a heterogeneous nodular mass. Nuclear magnetic resonance (NMR) of the liver showed an 11-cm mass centered on the hilum, dilated intrahepatic bile ducts, involvement of the hepatic veins, and hilar adenopathy.

Woman to Woman (W2W) is a novel adaptation of the Sisters Informing Sisters about Topics on AIDS (SISTA) HIV prevention program. This article describes the process of adapting and piloting W2W based on recommendations from existing HIV prevention research. Six older women, all of whom had histories of homelessness and the majority of whom identified as African American, enrolled in the study, which piloted the adapted intervention and materials, evaluated the acceptability of the program, and assessed the measures related to the intervention. Participants described satisfaction with the program and had high rates of attendance; observations regarding the measures suggest the need to further develop assessments of HIV knowledge, condom use self-efficacy, and risk behaviors in this context.

A combined intervention of strength and endurance training is common practice in elite swimming training, but the scientific evidence is scarce. The influences between strength and endurance training have been investigated in other sports but the findings are scattered. Some state the interventions are negative to each other, some state there is no negative relationship and some find bisected and supplementary benefits from the combination when training is applied appropriately. The aim of this study was to investigate the impact of a combined intervention among competitive swimmers. 20 subjects assigned to a training intervention group (n = 11) or a control group (n = 9) from two different teams completed the study. Anthropometrical data, tethered swimming force, land strength, performance in 50m, 100m and 400m, work economy, peak oxygen uptake, stroke length and stroke rate were investigated in all subjects at pre- and post-test. A combined intervention of maximal strength and high aerobic intensity interval endurance training 2 sessions per week over 11 weeks in addition to regular training were used, while the control group continued regular practice with their respective teams. The intervention group improved land strength, tethered swimming force and 400m freestyle performance more than the control group. The improvement of the 400m was correlated with the improvement of tethered swimming force in the female part of the intervention group. No change occurred in stroke length, stroke rate, performance in 50m or 100m, swimming economy or peak oxygen uptake during swimming. Two weekly dry-land strength training sessions for 11 weeks increase tethered swimming force in competitive swimmers. This increment further improves middle distance swimming performance. 2 weekly sessions of high- intensity interval training does not improve peak oxygen uptake compared with other competitive swimmers. Key pointsTwo weekly sessions of dry land strength training improves the

Full Text Available Background: The most important trunk stabilizers are the trunk flexors and extensors. The isometric endurance of the trunk muscles is an essential element for mechanical support of the spine in all positions. The study objectives were to find out the trunk flexors and extensors endurance, its relationship with normal BMI and to find out the ratio of trunk flexors to extensors endurance. Methods: In this correlation study, 50 subjects were selected by convenience sampling method on the basis of inclusion and exclusion criteria from Asia metropolitan university, Malaysia. The trunk flexors and extensors endurance were assessed by Kraus- Weber and Sorenson test respectively. Paired 't' test and Spearman correlation test were used for data analysis. Results: There was a significant difference (p 0.01 and TEE, rs (50 = -0.162, p >0.01 but there was a significant strong positive relationship between TFE and TEE, rs (50 = 0.68, p < 0.01. The ratio of trunk flexors to extensors was 0.61. Conclusion: The trunk extensors endurance is higher than trunk flexors endurance and BMI has no relationship with trunk flexors and extensors muscle endurance. The ratio of trunk flexors to extensors endurance value is low

Full Text Available Human parechovirus type 3 (HPeV3 can cause serious conditions in neonates, such as sepsis and encephalitis, but data for adults are lacking. The case of a pregnant woman with HPeV3 infection is reported herein. A 28-year-old woman at 36 weeks of pregnancy was admitted because of myalgia and muscle weakness. Her grip strength was 6.0 kg for her right hand and 2.5 kg for her left hand. The patient’s symptoms, probably due to fasciitis and not myositis, improved gradually with conservative treatment, however labor pains with genital bleeding developed unexpectedly 3 days after admission. An obstetric consultation was obtained and a cesarean section was performed, with no complications. A real-time PCR assay for the detection of viral genomic ribonucleic acid against HPeV showed positive results for pharyngeal swabs, feces, and blood, and negative results for the placenta, umbilical cord, umbilical cord blood, amniotic fluid, and breast milk. The HPeV3 was genotyped by sequencing of the VP1 region. The woman made a full recovery and was discharged with her infant in a stable condition.

We report a case of neuroleptic malignant syndrome in a woman who assumed risperidone for schizoaffective disorders. A 45-year-old woman affected by schizoaffective disorders was admitted to Infectious Disease unit of Crotone Hospital because of a diagnosis of a fever of unknown origin. Clinical evaluation documented confusion and dysphoria, whereas chemical blood evaluation revealed acidosis and liver dysfunction. After few days she was transferred to the Operative Unit of Internal Medicine of San Giovanni in Fiore Hospital because of an increase in liver transaminases. Clinical evaluation showed the persistence of fever (38.8 degrees Celsius), with an increase in CPK, and liver enzymes. Pharmacological evaluation indicated a probable relationship between risperidone and NMS and led to a diagnosis of neuroleptic malignant syndrome associated with risperidone in a woman with schizophrenia. About seven days later, we recorded a complete resolution of her psychiatric symptoms. We postulate a possible interaction between risperidone and neuroleptic malignant syndrome and we suggest to use risperidone with caution in both young and middle aged people.

The numerical dosimetry of pregnant women is an important issue in electromagnetic-field safety. However, an anatomically realistic whole-body pregnant-woman model for electromagnetic dosimetry has not been developed. Therefore, we have developed a high-resolution whole-body model of pregnant women. A new fetus model including inherent tissues of pregnant women was constructed on the basis of abdominal magnetic resonance imaging data of a 26-week-pregnant woman. The whole-body pregnant-woman model was developed by combining the fetus model and a nonpregnant-woman model that was developed previously. The developed model consists of about 7 million cubical voxels of 2 mm size and is segmented into 56 tissues and organs. This pregnant-woman model is the first completely anatomically realistic voxel model that includes a realistic fetus model and enables a numerical simulation of electromagnetic dosimetry up to the gigahertz band. In this paper, we also present the basic specific absorption rate characteristics of the pregnant-woman model exposed to vertically and horizontally polarized electromagnetic waves from 10 MHz to 2 GHz

Extrinsic compression of the left atrium by the esophagus, the stomach, or both is an uncommon but important cause of hemodynamic compromise. Achalasia is a motility disorder characterized by impaired relaxation of the lower esophageal sphincter and dilatation of the distal two thirds of the esophagus. Echocardiographic imaging after oral ingestion of liquid containing carbon dioxide allowed for differentiation between a compressive vascular structure and the esophagus. We report a rare case of esophageal achalasia compressing the left atrium diagnosed by echocardiography using a liquid containing carbon dioxide in a 21-year-old woman with Turner syndrome.

The purpose of this study was to assess the effects of heavy resistance, explosive resistance, and muscle endurance training on neuromuscular, endurance, and high-intensity running performance in recreational endurance runners. Twenty-seven male runners were divided into one of three groups: heavy resistance, explosive resistance or muscle endurance training. After 6 weeks of preparatory training, the groups underwent an 8-week resistance training programme as a supplement to endurance training. Before and after the 8-week training period, maximal strength (one-repetition maximum), electromyographic activity of the leg extensors, countermovement jump height, maximal speed in the maximal anaerobic running test, maximal endurance performance, maximal oxygen uptake ([V·]O(₂max)), and running economy were assessed. Maximal strength improved in the heavy (P = 0.034, effect size ES = 0.38) and explosive resistance training groups (P = 0.003, ES = 0.67) with increases in leg muscle activation (heavy: P = 0.032, ES = 0.38; explosive: P = 0.002, ES = 0.77). Only the heavy resistance training group improved maximal running speed in the maximal anaerobic running test (P = 0.012, ES = 0.52) and jump height (P = 0.006, ES = 0.59). Maximal endurance running performance was improved in all groups (heavy: P = 0.005, ES = 0.56; explosive: P = 0.034, ES = 0.39; muscle endurance: P = 0.001, ES = 0.94), with small though not statistically significant improvements in [V·]O(₂max) (heavy: ES = 0.08; explosive: ES = 0.29; muscle endurance: ES = 0.65) and running economy (ES in all groups running endurance performance. However, both heavy and explosive strength training were beneficial in improving neuromuscular characteristics, and heavy resistance training in particular contributed to improvements in high-intensity running characteristics. Thus, endurance runners should include heavy resistance training in their training programmes to enhance endurance performance, such as

Plutonium in an enduring fuel cycle

International Nuclear Information System (INIS)

Pillay, K.K.S.

1998-05-01

Nuclear fuel cycles evolved over the past five decades have allowed many nations of the world to enjoy the benefits of nuclear energy, while contributing to the sustainable consumption of the world's energy resources. The nuclear fuel cycle for energy production suffered many traumas since the 1970s because of perceived risks of proliferation of nuclear weapons. However, the experience of the past five decades has shown that the world community is committed to safeguarding all fissile materials and continuing the use of nuclear energy resources. Decisions of a few nations to discard spent nuclear fuels in geologic formations are contrary to the goals of an enduring nuclear fuel cycle and sustainable development being pursued by the world community. The maintenance of an enduring nuclear fuel cycle is dependent on sensible management of all the resources of the fuel cycle, including spent fuels

Full Text Available Plyometric training and beta-alanine supplementation are common among soccer players, although its combined use had never been tested. Therefore, a randomized, double-blind, placebo-controlled trial was conducted to compare the effects of a plyometric training program, with or without beta-alanine supplementation, on maximal-intensity and endurance performance in female soccer players during an in-season training period. Athletes (23.7 ± 2.4 years were assigned to either a plyometric training group receiving a placebo (PLACEBO, n = 8, a plyometric training group receiving beta-alanine supplementation (BA, n = 8, or a control group receiving placebo without following a plyometric training program (CONTROL, n = 9. Athletes were evaluated for single and repeated jumps and sprints, endurance, and change-of-direction speed performance before and after the intervention. Both plyometric training groups improved in explosive jumping (ES = 0.27 to 1.0, sprinting (ES = 0.31 to 0.78, repeated sprinting (ES = 0.39 to 0.91, 60 s repeated jumping (ES = 0.32 to 0.45, endurance (ES = 0.35 to 0.37, and change-of-direction speed performance (ES = 0.36 to 0.58, whereas no significant changes were observed for the CONTROL group. Nevertheless, compared to the CONTROL group, only the BA group showed greater improvements in endurance, repeated sprinting and repeated jumping performances. It was concluded that beta-alanine supplementation during plyometric training may add further adaptive changes related to endurance, repeated sprinting and jumping ability.

Plyometric training and beta-alanine supplementation are common among soccer players, although its combined use had never been tested. Therefore, a randomized, double-blind, placebo-controlled trial was conducted to compare the effects of a plyometric training program, with or without beta-alanine supplementation, on maximal-intensity and endurance performance in female soccer players during an in-season training period. Athletes (23.7 ± 2.4 years) were assigned to either a plyometric training group receiving a placebo (PLACEBO, n = 8), a plyometric training group receiving beta-alanine supplementation (BA, n = 8), or a control group receiving placebo without following a plyometric training program (CONTROL, n = 9). Athletes were evaluated for single and repeated jumps and sprints, endurance, and change-of-direction speed performance before and after the intervention. Both plyometric training groups improved in explosive jumping (ES = 0.27 to 1.0), sprinting (ES = 0.31 to 0.78), repeated sprinting (ES = 0.39 to 0.91), 60 s repeated jumping (ES = 0.32 to 0.45), endurance (ES = 0.35 to 0.37), and change-of-direction speed performance (ES = 0.36 to 0.58), whereas no significant changes were observed for the CONTROL group. Nevertheless, compared to the CONTROL group, only the BA group showed greater improvements in endurance, repeated sprinting and repeated jumping performances. It was concluded that beta-alanine supplementation during plyometric training may add further adaptive changes related to endurance, repeated sprinting and jumping ability.

To evaluate whether in a population of patients with 'lone atrial flutter', the proportion of those engaged in long-term endurance sports is higher than that observed in the general population. An age and sex-matched retrospective case-control study. A database with 638 consecutive patients who underwent ablation for atrial flutter at the University of Leuven. Sixty-one patients (55 men, 90%) fitted the inclusion criteria of 'lone atrial flutter', ie, aged 65 years or less, without documented atrial fibrillation and without identifiable underlying disease (including hypertension). Sex, age and inclusion criteria-matched controls, two for each flutter patient, were selected in a general practice in the same geographical region. Sports activity was evaluated by detailed questionnaires, which were available in 58 flutter patients (95%). A transthoracic echocardiogram was performed in all lone flutter patients. Types of sports, number of years of participation and average number of hours per week. The proportion of regular sportsmen (≥3 h of sports practice per week) among patients with lone atrial flutter was significantly higher than that observed in the general population (50% vs 17%; pendurance sports (participation in cycling, running or swimming for ≥3 h/week) was also significantly higher in lone flutter patients than in controls (31% vs 8%; p=0.0003). Those flutter patients performing endurance sports had a larger left atrium than non-sportsmen (p=0.04, by one-way analysis of variance). A history of endurance sports and subsequent left atrial remodelling may be a risk factor for the development of atrial flutter.

Altitude training is commonly used by endurance athletes and coaches in pursuit of enhancement of performance on return to sea level. The purpose of the current review article was to update and evaluate recent literature relevant to the practical application of altitude training for endurance athletes. Consequently, the literature can be considered in either of two categories: performance-led investigations or mechanistic advancements/insights. Each section discusses the relevant literature and proposes future directions where appropriate.

Ancient and modern women in the "Woman's World".

Science.gov (United States)

Hurst, Isobel

2009-01-01

Under the editorship of Oscar Wilde, the "Woman's World" exemplified the popular dissemination of Hellenism through periodical culture. Addressing topics such as marriage, politics, and education in relation to the lives of women in the ancient world, the magazine offered an unfamiliar version of the reception of ancient Greece and Rome in late-Victorian aestheticism, one that was accessible to a wide readership because it was often based on images rather than texts. The classical scholar Jane Ellen Harrison addressed herself to this audience of women readers, discussing the similarities between modern collegiate life and the "woman's world" that enabled Sappho to flourish in ancient Greece. The "Woman's World" thus questions gender stereotypes by juxtaposing ancient and modern women, implicitly endorsing varied models of womanhood.

This study examined the effects of endurance exercise on nocturnal autonomic modulation. Nocturnal R-R intervals were collected after a rest day, after a moderate endurance exercise and after a marathon run in ten healthy, physically active men. Heart rate variability (HRV) was analyzed as a continuous four-hour period starting 30 min after going to bed for sleep. In relation to average nocturnal heart rate after rest day, increases to 109+/-6% and 130+/-11% of baseline were found after moderate endurance exercise and marathon, respectively. Standard deviation of R-R intervals decreased to 90+/-9% and 64+/-10%, root-mean-square of differences between adjacent R-R intervals to 87+/-10% and 55+/-16%, and high frequency power to 77+/-19% and 34+/-19% of baseline after moderate endurance exercise and marathon, respectively. Also nocturnal low frequency power decreased to 56+/-26% of baseline after the marathon. Changes in nocturnal heart rate and HRV suggest prolonged dose-response effects on autonomic modulation after exercises, which may give useful information on the extent of exercise-induced nocturnal autonomic modulation and disturbance to the homeostasis.

Obesity is a national health problem regularly confronting medical professionals. Although reduced-energy (kilocalorie [kcal]) eating and increased exercise will reliably reduce weight, these behaviors have been highly resistant to sustained change. To control eating using theory-based cognitive-behavioral methods that leverage the positive psychosocial effects of newly initiated exercise as an alternate to typical approaches of education about appropriate nutrition. A woman, age 48 years, with morbid obesity initiated exercise through a 6-month exercise support protocol based on social cognitive and self-efficacy theory (The Coach Approach). This program was followed by periodic individual meetings with a wellness professional intended to transfer behavioral skills learned to adapt to regular exercise, to then control eating. There was consistent recording of exercises completed, foods consumed, various psychosocial and lifestyle factors, and weight. Over the 4.4 years reported, weight decreased from 117.6 kg to 59.0 kg, and body mass index (BMI) decreased from 43.1 kg/m(2) to 21.6 kg/m(2). Mean energy intake initially decreased to 1792 kcal/day and further dropped to 1453 kcal/day by the end of the weight-loss phase. Consistent with theory, use of self-regulatory skills, self-efficacy, and overall mood significantly predicted both increased exercise and decreased energy intake. Morbid obesity was reduced to a healthy weight within 3.1 years, and weight was maintained in the healthy range through the present (1.3 years later). This case supports theory-based propositions that exercise-induced changes in self-regulation, self-efficacy, and mood transfer to and reinforce improvements in corresponding psychosocial factors related to controlled eating.

Marathon running has been linked with higher arterial stiffness. Blood pressure is a major contributor to pulse wave velocity (PWV). We examined indices of arterial stiffness with a blood pressure-independent method in marathon runners and ultra-endurance athletes. Male normotensive amateur runners were allocated to three groups according to former participation in competitions: group I (recreational athletes), group II (marathon runners) and group III (ultra-endurance athletes). Indices of arterial stiffness were measured with a non-invasive device (VaSera VS-1500N, Fukuda Denshi, Japan) to determine the cardio-ankle vascular index (CAVI, primary endpoint) and brachial-ankle PWV (baPWV). Lifetime training hours were calculated. Cumulative competitions were expressed as marathon equivalents. Linear regression analysis was performed to determine predictors for CAVI and baPWV. Measurements of arterial stiffness were performed in 51 subjects (mean age 44.6 ± 1.2 years): group I (n = 16), group II (n = 19) and group III (n = 16). No between-group differences existed in age, anthropometric characteristics and resting BP. CAVI and baPWV were comparable between all groups (P = 0.604 and P = 0.947, respectively). In linear regression analysis, age was the only independent predictor for CAVI (R(2) = 0.239, β = 0.455, P = 0.001). Systolic BP was significantly associated with baPWV (R(2) = 0.225, β = 0.403, P = 0.004). In middle-aged normotensive athletes marathon running and ultra-endurance sports had no negative impact on arterial stiffness.

The value of enduring environmental surrogates as predictors of estuarine benthic macroinvertebrate assemblages

Science.gov (United States)

Wildsmith, Michelle D.; Valesini, Fiona J.; Robinson, Samuel F.

2017-10-01

This study tested the extent to which spatial differences in the benthic macroinvertebrate assemblages of a temperate microtidal estuary were 'explained' by the enduring (biophysical) vs non-enduring (water and sediment quality) environmental attributes of a diverse range of habitats, and thus the potential of those environmental surrogates to support faunal prediction. Species composition differed significantly among habitats in each season, with the greatest differences occurring in winter and spring and the least in summer. The pattern of habitat differences, as defined by their enduring environmental characteristics, was significantly and well matched with that in the fauna in each season. In contrast, significant matches between the non-enduring environmental and faunal data were only detected in winter and/or spring, and to a lesser extent. Field validation of the faunal prediction capacity of the biophysical surrogate framework at various 'test' sites throughout the estuary showed good agreement between the actual vs predicted key species. These findings demonstrate that enduring environmental criteria, which can be readily measured from mapped data, provide a better and more cost-effective surrogate for explaining spatial differences in the invertebrate fauna of this system than non-enduring criteria, and are thus a promising basis for faunal prediction. The approaches developed in this study are also readily adapted to any estuary worldwide.

Toward an understanding of the cerebral substrates of woman's orgasm.

The way women experience orgasm is of interest to scientists, clinicians, and laypeople. Whereas the origin and the function of a woman's orgasm remains controversial, the current models of sexual function acknowledge a combined role of central (spinal and cerebral) and peripheral processes during orgasm experience. At the central level, although it is accepted that the spinal cord drives orgasm, the cerebral involvement and cognitive representation of a woman's orgasm has not been extensively investigated. Important gaps in our knowledge remain. Recently, the astonishing advances of neuroimaging techniques applied in parallel with a neuropsychological approach allowed the unravelling of specific functional neuroanatomy of a woman's orgasm. Here, clinical and experimental findings on the cortico-subcortical pathway of a woman's orgasm are reviewed and compared with the neural basis of a man's orgasm. By defining the specific brain areas that sustain the assumed higher-order representation of a woman's orgasm, this review provides a foundation for future studies. The next challenge of functional imaging and neuropsychological studies is to understand the hierarchical interactions between these multiple cortical areas, not only with a correlation analysis but also with high spatio-temporal resolution techniques demonstrating the causal necessity, the temporal time course and the direction of the causality. Further studies using a multi-disciplinary approach are needed to identify the spatio-temporal dynamic of a woman's orgasm, its dysfunctions and possible new treatments.

2011-01-01

Physical inactivity is considered as one of the potential risk factors for the development of type 2 diabetes and other metabolic diseases, while endurance exercise training could enhance fat oxidation that is associated with insulin sensitivity improvement in obesity. AMP-activated protein kinase (AMPK) as an energy sensor plays pivotal roles in the regulation of energy homeostasis, and its activation could improve glucose uptake, promote mitochondrial biogenesis and increase glycolysis. Recent research has even suggested that AMPK activation contributed to endurance enhancement without exercise. Here we report that the natural product arctigenin from the traditional herb Arctium lappa L. (Compositae) strongly increased AMPK phosphorylation and subsequently up-regulated its downstream pathway in both H9C2 and C2C12 cells. It was discovered that arctigenin phosphorylated AMPK via calmodulin-dependent protein kinase kinase (CaMKK) and serine/threonine kinase 11(LKB1)-dependent pathways. Mice treadmill based in vivo assay further indicated that administration of arctigenin improved efficiently mice endurance as reflected by the increased fatigue time and distance, and potently enhanced mitochondrial biogenesis and fatty acid oxidation (FAO) related genes expression in muscle tissues. Our results thus suggested that arctigenin might be used as a potential lead compound for the discovery of the agents with mimic exercise training effects to treat metabolic diseases. PMID:21887385

2013-10-01

The potential ergogenic effects of therapeutic inhaled salbutamol doses in endurance athletes have been controversially discussed for decades. We hypothesized that salbutamol inhalation may increase peripheral muscle contractility, reduce fatigability, and improve force recovery after a localized exercise in endurance athletes. Eleven healthy, nonasthmatic male athletes with high aerobic capacities were recruited to be compared in a double-blinded, randomized crossover study of two dose levels of salbutamol (200 and 800 μg) and a placebo administered by inhalation before a quadriceps fatigue test. Subjects performed an incremental exercise protocol consisting in sets of 10 intermittent isometric contractions starting at 20% of maximum voluntary contraction (MVC) with 10% MVC increment until exhaustion. Femoral nerve magnetic stimulation was used during and after MVC to evaluate neuromuscular fatigue after each set, at task failure, and after 10 and 30 min of recovery. Initial MVC and evoked muscular responses were not modified with salbutamol (P > 0.05). The total number of submaximal contractions until task failure significantly differed between treatments (placebo, 72 ± 7; 200 µg, 78 ± 8; and 800 µg, 82 ± 7; P 0.05). Voluntary activation was unaffected by the fatiguing task and treatments (P > 0.05). Supratherapeutic inhaled doses of β2-agonists increased quadriceps endurance during an incremental and localized fatiguing task in healthy endurance-trained athletes without significant effect on neuromuscular fatigue. Further studies are needed to clarify the underlying mechanisms.

Endurance time method for Seismic analysis and design of structures

International Nuclear Information System (INIS)

Estekanchi, H.E.; Vafai, A.; Sadeghazar, M.

2004-01-01

In this paper, a new method for performance based earthquake analysis and design has been introduced. In this method, the structure is subjected to accelerograms that impose increasing dynamic demand on the structure with time. Specified damage indexes are monitored up to the collapse level or other performance limit that defines the endurance limit point for the structure. Also, a method for generating standard intensifying accelerograms has been described. Three accelerograms have been generated using this method. Furthermore, the concept of Endurance Time has been described by applying these accelerograms to single and multi degree of freedom linear systems. The application of this method for analysis of complex nonlinear systems has been explained. Endurance Time method provides a uniform approach to seismic analysis and design of complex structures that can be applied in numerical and experimental investigations

Full Text Available Objective: To report the management of urinary tract obstruction and infection in a pregnant woman with unrepaired bladder exstrophy. Case Report: A 27-year-old pregnant woman with unrepaired bladder exstrophy was referred to our hospital with a complaint of bilateral flank pain in the second trimester. After two-dimensional abdominal ultrasound, magnetic resonance imaging and a urine analysis, she was diagnosed with an upper urinary tract infection due to ureteral obstruction secondary to unrepaired congenital bladder exstrophy and an intrauterine pregnancy. J-tube insertion was performed after locating the ureteral orifices and antibiotics were administered. Symptoms rapidly resolved. She delivered a normal male infant by caesarean section at 34 weeks of gestation. Conclusion: Standard urological management of the ureteral obstruction in pregnancy was successful in this extreme case of unrepaired bladder exstrophy associated with an intrauterine pregnancy. The perinatal outcome was good. Keywords: Bladder exstrophy, Infection, Pregnancy, Urinary tract

Massive vulvar edema in a woman with preeclampsia preceded the development of massive ascites and impending eclampsia. A 17-year-old preeclamptic, primiparous woman was admitted with preeclampsia and massive vulvar edema. Other causes were excluded. The vulvar edema increased as the blood pressure and ascites increased, and a severe headache developed. Cesarean section for increasing preclampsia was performed. In the puerperium, the blood pressure improved and vulvar edema resolved. The clinical picture of the vulvar edema correlated with the severity of the preeclampsia. The presence of vulvar edema in women with preeclampsia should indicate immediate admission to the hospital. These patients must be considered as at high risk, and close monitoring must be instituted. In our case, vulvar edema preceded massive ascites development. We assume a common development mechanism for these signs in preeclampsia, due mainly to increased capillary permeability and hypoalbuminemia. The attending physician must be prepared for immediate delivery and possible preeclampsia complications in these patients.

The main aims of this study were to compare the neck flexor and extensor endurance and forward head posture between adolescents with and without neck pain. The secondary aims were to explore potential associations between muscles endurance, head posture and neck pain characteristics and to assess intra-rater reliability of the measurements used. Adolescents with neck pain (n = 35) and age-matched asymptomatic adolescents (n = 35) had their forward head posture, neck flexor endurance and neck extensor endurance measured using clinical tests. Intra-rater reliability was also assessed. Forward head posture and neck flexor and extensor endurance tests showed moderate to almost perfect intra-rater reliability (ICC between 0.58 and 0.88). Adolescents with neck pain showed significantly less forward head posture (neck pain = 46.62 ± 4.92; asymptomatic = 44.18°± 3.64°, p > 0.05) and less neck flexor (neck pain = 24.50 ± 23.03s; asymptomatic = 35.89 ± 21.53s, p > 0.05) and extensor endurance (neck pain = 12.6.64 ± 77.94s; asymptomatic = 168.66 ± 74.77s, p > 0.05) than asymptomatic adolescents. Results suggest that changes in posture and neck muscle endurance are a feature of adolescents with neck pain. Copyright © 2015 Elsevier Ltd. All rights reserved.

Performing at an elite level in Nordic combined (NC) requires both the explosiveness required for ski jumping performance and the endurance capacity required for cross-country skiing. To describe the characteristics of world-class NC athletes' training and determine how endurance and non-endurance (ie, strength, power, and ski jumping) training is periodized. Annual training characteristics and the periodization of endurance and non-endurance training were determined by analyzing the training diaries of 6 world-class NC athletes. Of 846 ± 72 annual training hours, 540 ± 37 h were endurance training, with 88.6% being low-, 5.9% moderate-, and 5.5% high-intensity training. While training frequency remained relatively constant, the total training volume was reduced from the general preparatory to the competition phase, primarily due to less low- and moderate-intensity training (P ski-jump-specific training (908 ± 165 ski jumps and ski-jump imitations). The proportion of non-endurance training increased significantly toward the competition phase (P ski-jump training. These data provide novel insight on how successful athletes execute their training and may facilitate more-precise coaching of future athletes in this sport. In addition, this information is of high relevance for the training organization of other sports that require optimization of 2 fundamentally different physical capacities.

In endurance-trained men, an acute bout of exercise is shown to suppress post-exercise appetite, yet limited research has examined this response in women. The purpose of this study was to investigate the effect of exercise intensity on appetite and gut hormone responses in endurance-trained women. Highly-trained women (n = 15, 18–40 years, 58.4 ± 6.4 kg, VO2MAX = 55.2 ± 4.3 mL/kg/min) completed isocaloric bouts (500 kcals or 2093 kJ) of moderate-intensity (MIE, 60% VO2MAX) and high-intensity (HIE, 85% VO2MAX) treadmill running at the same time of day, following a similar 48-h diet/exercise period, and at least 1-week apart. Blood was drawn pre-exercise (baseline), immediately post-exercise and every 20-min for the next 60-min. Plasma concentrations of acylated ghrelin, PYY3–36, GLP-1 and subjective appetite ratings via visual analog scale (VAS) were assessed at each time point. Acylated ghrelin decreased (p = 0.014) and PYY3–36 and GLP-1 increased (p = 0.036, p appetite suppression. VAS ratings of hunger and desire to eat decreased immediately post-exercise (p = 0.0012, p = 0.0031, respectively), also indicating appetite suppression. There were no differences between exercise intensities for appetite hormones or VAS. Similar to males, post-exercise appetite regulatory hormones were altered toward suppression in highly-trained women and independent of energy cost of exercise. Results are important for female athletes striving to optimize nutrition for endurance performance. PMID:27096869

Full Text Available Unverricht-Lundborg disease (ULD is an autosomal recessive progressive myoclonic epilepsy. The prevalence is highest in specific European countries and North Africa. Affected individuals have myoclonic and tonic-clonic seizures and a variable degree of ataxia and cognitive impairment. We report a native Haitian woman with ULD who was wheelchair bound due to nearly continuous myoclonic seizures exacerbated by activity and emotional distress. The seizures and their dramatic increase with volitional activity were recorded during video electroencephalography monitoring. Rational antiepileptic drug therapy controlled the seizures well enough for the patient to achieve a level of independence she had not experienced in over 25 years.

Every year 42 million women with unintended pregnancies choose abortion, and fifty percent of these procedures, 20 million are unsafe. An unsafe abortion is defined as a procedure for terminating an unintended pregnancy carried out either by person lacking the necessary skills or in an environment that does not conform to minimal medical standards or both.Pakistan is the one of the six countries where more than 50% of the world's all maternal deaths occur. It is estimated that 890,000 induced abortions are performed annually in Pakistan, and estimate an annual abortion rate of 29 per 1000 women aged 15-49. Here we present a case report of a 29-year old woman who underwent an unsafe abortion for unintended pregnancy resulting in uterine perforation. The unskilled provider pulled out her bowel through vagina after perforating the uterus, as a result she lost major portion of her small intestine resulting in short bowel syndrome. The law of Pakistan only allows abortion during early stages of pregnancy for purpose of saving the life of a mother but does not cater for cases of rape, incest and fetal abnormalities or social reasons.Only legalization of abortion is not sufficient, preventing unintended pregnancy should be the priority of all the nations and for this reason contraception should be widely accessible.Practitioners need to become better trained in safer abortion methods and be to able transfer the patient to health facility when complications occur.

Full Text Available

The purpose of the current study was to determine whether a strength endurance training program of lower limbs isolate can increase endurance levels, both aerobic capacity and aerobic power, in order to adapt the strength training for endurance races. 20 phisically active men participated in the study. They were divided into two groups: control group (GC (n=10 and experimental group (GE (n=10. GE carried out a strength endurance training program for ten weeks. Results obtained showed that this type of training regime was useful to improve the performance in an aerobic endurance test. This could be due to an improvement in aerobic capacity, maximal dynamic strength, explosive strength and reactive strength. Moreover, there was a decrease in fat mass without increase in muscle mass.
Key Words:  Training, strength endurance, aerobic capacity, anthropometry.

Full Text Available The purpose of the present study was to examine the effects of additional in-season speed endurance production versus speed endurance maintenance training regimes on performance in competitive male soccer players. In a randomised controlled trial 18 male sub-elite players were exposed to additional speed endurance production (SEP or speed endurance maintenance (SEM training (two additional sessions/wk for 4 weeks during the competitive season. Players performed the Yo-Yo intermittent recovery level 2 test (YYIR2 and a repeated sprint test (RST pre- and post-intervention. Yo-Yo IR2 performance increased (p<0.001 by 50 ± 8% and 26 ± 5% in SEP and SEM, respectively, with greater (p=0.03 improvement in SEP. RST performance improved by 2.1 ± 0.3% and 1.3 ± 0.4% in SEP and SEM, respectively, while the RST fatigue index decreased (4.4 ± 0.8 to 3.4 ± 0.5%; p<0.04 in SEP only. Peak and average speed during training were higher (p<0.001 in SEP than in SEM (24.5 ± 0.3 vs 19.2 ± 0.3 and 15.5 ± 0.1 km·h-1 vs 9.4 ± 0.1 km·h-1. Additional in-season anaerobic speed endurance production and maintenance training improves high-intensity exercise performance in competitive soccer players with superior effects of speed endurance production training.

Erdem, Devrim; Şayli, Ömer; Karahan, Mustafa; Akin, A.

2006-02-01

In this paper, the changes in muscle deoxygenation trends during a sustained isometric quadriceps (chair squat/half squat) endurance exercise were evaluated among twelve male subjects and the relationship between muscle oxygenation and endurance times was investigated by means of functional near-infrared spectroscopy (fNIRS). Neuromuscular activation and predictions of muscle performance decrements during extended fatiguing task was investigated by means of surface electromyography (sEMG). The results of the study showed that in the subjects who maintained exercise longer than five minutes (group 1), mean Hb recovery time (33 [sec.]) was 37.4% less than the others (group 2, 52.7 [sec.]). Also mean HbO II decline amplitude (2.53 [a.u.] in group 1 and 2.07 [a.u.] in group 2) and oxy decline amplitude (8.4 [a.u.] in group 1 and 3.04 [a.u.] in group 2) in the beginning of squat exercise are found to be 22.6% and 176.9% bigger in these group. For the EMG parameters, mean slope of MNF and MDF decline are found to be 57.5% and 42.2% bigger in magnitude in group 2 which indicates higher degree of decrement in mean and median frequencies although their mean squat duration time is less. This indicates higher index of fatigue for this group. It is concluded that training leads to altered oxygenation and oxygen extraction capability in the exercising muscle and investigated fNIRS parameters could be used for endurance evaluation.

Some federal courts have used a reasonable woman standard rather than the traditional reasonable man or reasonable person standard to determine whether hostile environment sexual harassment has occurred. The current research examined the impact of the reasonable woman standard on federal district court decisions, controlling for other factors found to affect sexual harassment court decisions. Results indicated that there was a weak relationship between whether a case followed a reasonable woman precedent-setting case and the likelihood that the court decision favored the plaintiff. The implications of our findings for individuals and organizations involved in sexual harassment claims are discussed.

Full Text Available This study examines the career women who use the habit of treating the body through the routine of coming to spas, which aims to overcome the dominance of patriarchy. This study uses several concepts. First, muted group theory, which states that woman, is the one that silenced; so to overcome this condition, women should perform self-transformation. The transformation is aligned with the second concept, feminist existentialist, which defines the transformation as the change of a woman concept from Other to Self. The transformation can be achieved not only by working outside the domestic sphere, but also supported by a good appearance through a complete body treatment. Grooming habits acquired through socialization that derived in woman since their childhood. The socialization is about how women as a person who is considered weak by the world of patriarchal domination using the power of their beauty to master, subdue, and break the domination in her life. Then, with their good appearance, woman can express their existence in everything that they do from object become subject. Spa and the whole result of the activities contained in it then consciously become a way of resistance that being used by the career woman against the domination of patriarchy which overshadowing their lives.

We present a case report on a 53-year-old transsexual woman who developed acute painless vision loss in both eyes during cross-sex hormone treatment. After 10 months of cross-sex hormone treatment, she experienced total vision loss of the right eye and, 6 months later, vision loss to 20/63 in the left eye. After a full ophthalmic exam, bilateral sequential non-arteritic ischemic optic neuropathy (NA-ION) was diagnosed. Extensive etiological work-up revealed no cardiac abnormalities or inherited blood-clotting disorders. A manifest self-administered overdose of transdermal estrogen treatment with serum estradiol levels of 5,765 pg/ml was possibly related to the sequential bilateral NA-ION resulting in nearly total vision loss in this transsexual woman.

Low back pain is a leading cause of disability in firefighters and is related to poor muscular endurance. This study examined the impact of supervised worksite exercise on back and core muscular endurance in firefighters. A cluster randomized controlled trial was used for this study. The study occurred in fire stations of a municipal fire department (Tampa, Florida). Subjects were 96 full-duty career firefighters who were randomly assigned by fire station to exercise (n = 54) or control (n = 42) groups. Exercise group participants completed a supervised exercise targeting the back and core muscles while on duty, two times per week for 24 weeks, in addition to their usual fitness regimen. Control group participants continued their usual fitness regimen. Back and core muscular endurance was assessed with the Biering-Sorensen test and plank test, respectively. Changes in back and core muscular endurance from baseline to 24 weeks were compared between groups using analysis of covariance and linear mixed effects models. After 24 weeks, the exercise group had 12% greater (p = .021) back muscular endurance and 21% greater (p = .0006) core muscular endurance than did the control group. The exercise intervention did not disrupt operations or job performance. A supervised worksite exercise program was safe and effective in improving back and core muscular endurance in firefighters, which could protect against future low back pain.

Marcell, Taylor J; Hawkins, Steven A; Wiswell, Robert A

2014-02-01

Age-associated loss of muscle mass (sarcopenia) and strength (dynapenia) is associated with a loss of independence that contributes to falls, fractures, and nursing home admissions, whereas regular physical activity has been suggested to offset these losses. The purpose of this study was to evaluate the effect of habitual endurance exercise on muscle mass and strength in active older adults. A longitudinal analysis of muscle strength (≈4.8 years apart) was performed on 59 men (age at start of study: 58.6 ± 7.3 years) and 35 women (56.9 ± 8.2 years) who used endurance running as their primary mode of exercise. There were no changes in fat-free mass although body fat increased minimally (1.0-1.5%). Training volume (km·wk, d·wk) decreased in both the men and women. There was a significant loss of both isometric knee extension (≈5% per year) and knee flexion (≈3.6% per year) strength in both the men and women. However, there was no significant change in either isokinetic concentric or eccentric torque of the knee extensors. Our data demonstrated a significant decline in isometric knee extensor and knee flexor strength although there were no changes in body mass in this group of very active older men and women. Our data support newer exercise guidelines for older Americans suggesting resistance training be an integral component of a fitness program and that running alone was not sufficient to prevent the loss in muscle strength (dynapenia) with aging.

The purpose of this study was to investigate the effects of a concurrent strength and endurance training program on running performance and running economy of middle-aged runners during their marathon preparation. Twenty-two (8 women and 14 men) recreational runners (mean ± SD: age 40.0 ± 11.7 years; body mass index 22.6 ± 2.1 kg·m⁻²) were separated into 2 groups (n = 11; combined endurance running and strength training program [ES]: 9 men, 2 women and endurance running [E]: 7 men, and 4 women). Both completed an 8-week intervention period that consisted of either endurance training (E: 276 ± 108 minute running per week) or a combined endurance and strength training program (ES: 240 ± 121-minute running plus 2 strength training sessions per week [120 minutes]). Strength training was focused on trunk (strength endurance program) and leg muscles (high-intensity program). Before and after the intervention, subjects completed an incremental treadmill run and maximal isometric strength tests. The initial values for VO2peak (ES: 52.0 ± 6.1 vs. E: 51.1 ± 7.5 ml·kg⁻¹·min⁻¹) and anaerobic threshold (ES: 3.5 ± 0.4 vs. E: 3.4 ± 0.5 m·s⁻¹) were identical in both groups. A significant time × intervention effect was found for maximal isometric force of knee extension (ES: from 4.6 ± 1.4 to 6.2 ± 1.0 N·kg⁻¹, p marathon running velocities (2.4 and 2.8 m·s⁻¹) and submaximal blood lactate thresholds (2.0, 3.0, and 4.0 mmol·L⁻¹). Stride length and stride frequency also remained unchanged. The results suggest no benefits of an 8-week concurrent strength training for running economy and coordination of recreational marathon runners despite a clear improvement in leg strength, maybe because of an insufficient sample size or a short intervention period.

Marie Curie: Physicist and Woman

Science.gov (United States)

Howes, Ruth

Marie Sklodowska was born in Warsaw on November 7, 1867. Girls were not allowed to attend college in Poland, so Marie found a well-paying post as a governess in rural village which she held for three years while helping her older sister complete medical school in Paris. Then Marie moved to Paris and graduated first in her class at the Sorbonne with a master's degree in physics in 1893. In 1895, she married the talented young physicist, Pierre Curie. Marie decided to investigate the radioactive components of the mineral pitchblende for her dissertation. The work involved chemical analysis of a ton of material in an unheated shed. Pierre joined her and at the end of 1898, the Curies announced the discovery of radium and polonium. Through 1899, Marie labored to measure the atomic weight of radium. In 1903, Marie earned her doctorate, the first for a woman in France, and the Curies split the Nobel Prize in Physics with Henri Becquerel. They became widely known, besieged by the press and frequently invited to make presentations and be awarded honors. They hated fame and both suffered bad health. In April, 1906, Pierre Curie was struck by a wagon and killed instantly. Marie was left as a single mother with two young daughters. Fortunately, the Sorbonne hired her to fill Pierre's position. In 1911, she was rejected for membership in the French Academy of Science because she was a woman. Also in 1911, she was accused of having an affair with a married French physicist Paul Langevin. The resulting scandal hit the press and brought angry mobs to her home. In the middle of this hullaballoo, she was informed that she had won a second Nobel Prize, this time in Chemistry. When World War I broke out, Marie mounted x-ray units on cars and became a heroine. She visited the United States in 1921 where President Harding presented her with a gram of radium. She continued her scientific studies in spite of declining health until her death in 1934. Professor Emerita.

Among-Individual Variation in Desert Iguanas (Squamata: Dipsosaurus dorsalis): Endurance Capacity Is Positively Related to Home Range Size.

Science.gov (United States)

Singleton, Jennifer M; Garland, Theodore

Among species of lizards, endurance capacity measured on a motorized treadmill is positively related to daily movement distance and time spent moving, but few studies have addressed such relationships at the level of individual variation within a sex and age category in a single population. Both endurance capacity and home range size show substantial individual variation in lizards, rendering them suitable for such studies. We predicted that these traits would be positively related because endurance capacity is one of the factors that has the potential to limit home range size. We measured the endurance capacity and home range size of adult male desert iguanas (Dipsosaurus dorsalis). Lizards were field captured for measurements of endurance, and home range data were gathered using visual identification of previously marked individuals. Endurance was significantly repeatable between replicate trials, conducted 1-17 d apart ([Formula: see text] for log-transformed values, [Formula: see text], [Formula: see text]). The log of the higher of two endurance trials was positively but not significantly related to log body mass. The log of home range area was positively but not significantly related to log body mass, the number of sightings, or the time span from first to last sighting. As predicted, log endurance was positively correlated with log home range area ([Formula: see text], [Formula: see text], one-tailed [Formula: see text]; for body-mass residual endurance values: [Formula: see text], one-tailed [Formula: see text]). These results suggest that endurance capacity may have a permissive effect on home range size. Alternatively, individuals with larger home ranges may experience training effects (phenotypic plasticity) that increase their endurance.

A phenomenological model of muscle fatigue and the power-endurance relationship.

Science.gov (United States)

James, A; Green, S

The relationship between power output and the time that it can be sustained during exercise (i.e., endurance) at high intensities is curvilinear. Although fatigue is implicit in this relationship, there is little evidence pertaining to it. To address this, we developed a phenomenological model that predicts the temporal response of muscle power during submaximal and maximal exercise and which was based on the type, contractile properties (e.g., fatiguability), and recruitment of motor units (MUs) during exercise. The model was first used to predict power outputs during all-out exercise when fatigue is clearly manifest and for several distributions of MU type. The model was then used to predict times that different submaximal power outputs could be sustained for several MU distributions, from which several power-endurance curves were obtained. The model was simultaneously fitted to two sets of human data pertaining to all-out exercise (power-time profile) and submaximal exercise (power-endurance relationship), yielding a high goodness of fit (R(2) = 0.96-0.97). This suggested that this simple model provides an accurate description of human power output during submaximal and maximal exercise and that fatigue-related processes inherent in it account for the curvilinearity of the power-endurance relationship.

A postmenopausal woman with sciatica from broad ligament leiomyoma: a case report.

Unilateral lower abdominal pain and/or sciatic nerve pain is a common presentation in the elderly population. The prevalence of broad ligament leiomyoma is leiomyomas to be clinically significant. Thus, we highlight a case of symptomatic broad ligament leiomyoma in a postmenopausal woman whose symptoms improved after definitive treatment. A 62-year-old postmenopausal Macedonian woman was referred to our gynecological department with unexplained pain in her left leg and left iliac fossa region on walking. There was minimal relief with increasing analgesia use prescribed by the family physician. Investigations revealed an ipsilateral adnexal mass and subsequent treatment with laparoscopic broad ligament myomectomy helped to alleviate her symptoms. Our case highlights the importance of staying mindful of alternate diagnoses when presented with a common presentation of iliac fossa pain and pain in the leg. Although broad ligament leiomyomas are benign tumors, the uncommon symptomatic presentation led us to report and focus some attention on this type of tumor.

Oró-Piqueras, Maricel

2014-12-01

The TV series, Brothers & Sisters, broadcast from 2006 to 2011 by ABC (USA) and a year later by Channel 4 (UK) with quite high audience rates, starts when the patriarchal figure, William Walker, dies of a heart attack and two female figures around their sixties come center stage: his wife, Nora Walker, and his long-term lover, Holly Harper. Once the patriarchal figure disappears, the female characters regain visibility by entering the labor market and starting relationships with other men. In that sense, both protagonists experience aging as a time in which they are increasingly freed from social and family constraints. However, their roles as nurturers keep on bringing them back to the domestic space in which they are safe from being involved in uncomfortable and unsuitable situations. Drawing on previous studies on the representation of the older woman in fictional media, this article intends to discern to what extent stereotypes related to the older woman are challenged through the two main protagonists of a contemporary TV series.

2016-01-01

In a randomised controlled trial design, effects of 6 weeks of plyometric training on maximal-intensity exercise and endurance performance were compared in male and female soccer players. Young (age 21.1 ± 2.7 years) players with similar training load and competitive background were assigned to training (women, n = 19; men, n = 21) and control (women, n = 19; men, n = 21) groups. Players were evaluated for lower- and upper-body maximal-intensity exercise, 30 m sprint, change of direction speed and endurance performance before and after 6 weeks of training. After intervention, the control groups did not change, whereas both training groups improved jumps (effect size (ES) = 0.35-1.76), throwing (ES = 0.62-0.78), sprint (ES = 0.86-1.44), change of direction speed (ES = 0.46-0.85) and endurance performance (ES = 0.42-0.62). There were no differences in performance improvements between the plyometric training groups. Both plyometric groups improved more in all performance tests than the controls. The results suggest that adaptations to plyometric training do not differ between men and women.

Full Text Available Introduction. Although pyogenic granulomas (PG are common and benign vascular proliferations of the skin and mucous membranes, they are relatively rare on the vulva. Case Presentation. A 57-year-old G7P7 postmenopausal woman presented with a 3-year history of a foul smell and bleeding lesions in the genital region. A gynecologic examination revealed multiple large papillomatous, pedunculated, and lobulated lesions that were cherry-red and infective in appearance. There was a 2-cm lesion at the upper intersection of the labia majora, a 2-cm lesion on the right labium majus, and a 4-cm lesion on the clitoris. The patient complained of itching, and the lesions were asymptomatic, except for occasional bleeding. All lesions were excised and sent for histopathological examination, which revealed an ulcerated polypoidal structure with extensive proliferation of vascular channels lined by a single layer of endothelium. The histopathological features were consistent with PG. Conclusion. The present case is the first case of multiple pyogenic granulomas on the vulva in a postmenopausal woman.

Helfer, Samuel; Quackenbush, Joseph; Fletcher, Michael; Pendergast, David R

2016-08-01

Climbing and trekking at altitude are common recreational and military activities. Physiological effects of altitude are hypoxia and hyperventilation. The hyperventilatory response to altitude may cause respiratory muscle fatigue and reduce sustained submaximal exercise. Voluntary isocapnic hyperpnea respiratory muscle training (VIHT) improves exercise endurance at sea level and at depth. The purpose of this study was to test the hypothesis that VIHT would improve exercise time at altitude [3600 m (11,811 ft)] compared to control and placebo groups. Subjects pedaled an ergometer until exhaustion at simulated altitude in a hypobaric chamber while noninvasive arterial saturation (Sao2), ventilation (VE), and oxygen consumption (Vo2) were measured. As expected, Sao2 decreased to 88 ± 4% saturation at rest and to 81 ± 2% during exercise, and was not affected by VIHT. VIHT resulted in a 40% increase in maximal training VE compared to pre-VIHT. Exercise endurance significantly increased 44% after VIHT (P = altitude post-VIHT increased more (49%) for longer (21 min) and decreased less (11% at 25.4 ± 6.7 min). VIHT improved exercise time at altitude and sustained VE. This suggests that VIHT reduced respiratory muscle fatigue and would be useful to trekkers and military personnel working at altitude.

'With woman' philosophy: examining the evidence, answering the questions.

Science.gov (United States)

Carolan, Mary; Hodnett, Ellen

2007-06-01

'With woman', 'woman centred' and 'in partnership with women' are new terms associated with midwifery care in Australia, and the underlying philosophy has emerged both as an antidote to the medicalisation of pregnancy and in a bid to reacquaint women with their natural capacity to give birth successfully and without intervention. A reorientation of midwifery services in the 1990s, a shift towards midwifery-led care (MLC) and the subsequent introduction of direct entry midwifery programs all contributed to this new direction. Central concepts are a focus on the childbearing woman and a valuing of women's experiences. While this philosophical re-alignment has been applauded by many midwives in terms of maternal empowerment and improved autonomy for midwives, there are nonetheless some concerns that, with its emphasis on normality, midwifery-led care is in danger of becoming an exclusionary model. Particular concerns include meeting the needs of a growing cohort of women, those with 'high risk' pregnancies, and the educational adequacy of direct entry midwifery programs. To date, there has been no thorough evaluation of this emerging midwifery philosophy in Australia. In order to open the debate, this paper aims to initiate a discussion of 'with woman' midwifery care as it applies to Australian practice.

SUSTAINED ISOMETRIC SHOULDER CONTRACTION ON MUSCULAR STRENGTH AND ENDURANCE: A RANDOMIZED CLINICAL TRIAL.

2015-12-01

The Advanced Throwers Ten Exercise Program incorporates sustained isometric contractions in conjunction with dynamic shoulder movements. It has been suggested that incorporating isometric holds may facilitate greater increases in muscular strength and endurance. However, no objective evidence currently exists to support this claim. The purpose of this research was to compare the effects of a sustained muscle contraction resistive training program (Advanced Throwers Ten Program) to a more traditional exercise training protocol to determine if increases in shoulder muscular strength and endurance occur in an otherwise healthy population. It was hypothesized that utilizing a sustained isometric hold during a shoulder scaption exercise from the Advanced Throwers Ten would produce greater increases in shoulder strength and endurance as compared to a traditional training program incorporating a isotonic scapular plane abduction (scaption) exercise. Randomized Clinical Trial. Fifty healthy participants were enrolled in this study, of which 25 were randomized into the traditional training group (age: 26 ± 8, height:172 ± 10 cm, weight: 73 ± 13 kg, Marx Activity Scale: 11 ± 4) and 25 were randomized to the Advanced Throwers Ten group (age: 28 ± 9, height: 169 ± 23 cm, weight: 74 ± 16 kg, Marx Activity Scale: 11 ± 5). No pre-intervention differences existed between the groups (P>0.05). Arm endurance and strength data were collected pre and post intervention using a portable load cell (BTE Evaluator, Hanover, MD). Both within and between group analyses were done in order to investigate average torque (strength) and angular impulse (endurance) changes. The traditional and Advanced Throwers Ten groups both significantly improved torque and angular impulse on both the dominant and non-dominant arms by 10-14%. There were no differences in strength or endurance following the interventions between the two training groups (p>0

Full Text Available The goal of the study was to assess the prevalence of stress urinary incontinence in a group of elite female endurance athletes, as professional sport is one of the risk factors for stress urinary incontinence. SUI rates in the groups of female cross-country skiers and runners were compared to determine whether the training weather conditions like temperature and humidity influenced the prevalence of urinary incontinence. An anonymous questionnaire was distributed among 112 elite female athletes ie., 57 cross-country skiers and 55 runners. We used a short form of the Urogenital Distress Inventory (UDI-6 to assess the presence of SUI symptoms and the level of urogenital distress. Only women who had been practicing sport professionally for at least 3 years, on an international and national level, were included in the research. The study group consisted of 76% nulliparous and 24% parous women. 45.54% of all participants reported leakage of urine associated with sneezing or coughing which indicates stress urinary incontinence. 29.46% were not bothered by the urogenital distress symptoms. 42.86% of the participants were slightly bothered by the symptoms, 18.75% were moderately bothered, 8.04% were significantly bothered and 0.89% were heavily bothered. The absence of statistically significant differences between both groups seems to indicate that training weather conditions did not influence the prevalence of SUI in elite female endurance athletes.

Children after Fontan palliation have reduced exercise capacity and quality of life. Our aim was to study whether endurance training could improve physical capacity and quality of life in Fontan patients. Fontan patients (n=30) and healthy age- and gender-matched control subjects (n=25) performed a 6-minute walk test at submaximal capacity and a maximal cycle ergometer test. Quality of life was assessed with Pediatric Quality of Life Inventory Version 4.0 questionnaires for children and parents. All tests were repeated after a 12-week endurance training programme and after 1 year. Patients had decreased submaximal and maximal exercise capacity (maximal oxygen uptake 35.0±5.1 ml/minute per·kg versus 43.7±8.4 ml/minute·per·kg, pquality of life score (70.9±9.9 versus 85.7±8.0, pimproved their submaximal exercise capacity in a 6-minute walk test (from 590.7±65.5 m to 611.8±70.9 m, pquality of life (pimprove maximal exercise capacity. At follow-up, submaximal exercise capacity had increased further and improved quality of life was sustained. The controls improved their maximal exercise capacity (pquality of life after training. At follow-up, improvement of maximal exercise capacity was sustained. We believe that an individualised endurance training programme for Fontan patients improves submaximal exercise capacity and quality of life in Fontan patients and the effect on quality of life appears to be long-lasting.

Effect of power system technology and mission requirements on high altitude long endurance aircraft

Colozza, Anthony J.

1994-01-01

An analysis was performed to determine how various power system components and mission requirements affect the sizing of a solar powered long endurance aircraft. The aircraft power system consists of photovoltaic cells and a regenerative fuel cell. Various characteristics of these components, such as PV cell type, PV cell mass, PV cell efficiency, fuel cell efficiency, and fuel cell specific mass, were varied to determine what effect they had on the aircraft sizing for a given mission. Mission parameters, such as time of year, flight altitude, flight latitude, and payload mass and power, were also altered to determine how mission constraints affect the aircraft sizing. An aircraft analysis method which determines the aircraft configuration, aspect ratio, wing area, and total mass, for maximum endurance or minimum required power based on the stated power system and mission parameters is presented. The results indicate that, for the power system, the greatest benefit can be gained by increasing the fuel cell specific energy. Mission requirements also substantially affect the aircraft size. By limiting the time of year the aircraft is required to fly at high northern or southern latitudes, a significant reduction in aircraft size or increase in payload capacity can be achieved.

Endurance athletes perform periodized training in order to prepare for main competitions and maximize performance. However, the coupling between alterations of total energy expenditure (TEE), energy intake, and body composition during different seasonal training phases is unclear. So far, no systematic review has assessed fluctuations in TEE, energy intake, and/or body composition in endurance athletes across the training season. The purpose of this study was to (1) systematically analyze TEE, energy intake, and body composition in highly trained athletes of various endurance disciplines and of both sexes and (2) analyze fluctuations in these parameters across the training season. An electronic database search was conducted on the SPORTDiscus and MEDLINE (January 1990-31 January 2015) databases using a combination of relevant keywords. Two independent reviewers identified potentially relevant studies. Where a consensus was not reached, a third reviewer was consulted. Original research articles that examined TEE, energy intake, and/or body composition in 18-40-year-old endurance athletes and reported the seasonal training phases of data assessment were included in the review. Articles were excluded if body composition was assessed by skinfold measurements, TEE was assessed by questionnaires, or data could not be split between the sexes. Two reviewers assessed the quality of studies independently. Data on subject characteristics, TEE, energy intake, and/or body composition were extracted from the included studies. Subjects were categorized according to their sex and endurance discipline and each study allocated a weight within categories based on the number of subjects assessed. Extracted data were used to calculate weighted means and standard deviations for parameters of TEE, energy intake, and/or body composition. From 3589 citations, 321 articles were identified as potentially relevant, with 82 meeting all of the inclusion criteria. TEE of endurance athletes was

Effects of Beetroot Juice Supplementation on Cardiorespiratory Endurance in Athletes. A Systematic Review

Full Text Available Athletes use nutritional supplementation to enhance the effects of training and achieve improvements in their athletic performance. Beetroot juice increases levels of nitric oxide (NO, which serves multiple functions related to increased blood flow, gas exchange, mitochondrial biogenesis and efficiency, and strengthening of muscle contraction. These biomarker improvements indicate that supplementation with beetroot juice could have ergogenic effects on cardiorespiratory endurance that would benefit athletic performance. The aim of this literature review was to determine the effects of beetroot juice supplementation and the combination of beetroot juice with other supplements on cardiorespiratory endurance in athletes. A keyword search of DialNet, MedLine, PubMed, Scopus and Web of Science databases covered publications from 2010 to 2016. After excluding reviews/meta-analyses, animal studies, inaccessible full-text, and studies that did not supplement with beetroot juice and adequately assess cardiorespiratory endurance, 23 articles were selected for analysis. The available results suggest that supplementation with beetroot juice can improve cardiorespiratory endurance in athletes by increasing efficiency, which improves performance at various distances, increases time to exhaustion at submaximal intensities, and may improve the cardiorespiratory performance at anaerobic threshold intensities and maximum oxygen uptake (VO2max. Although the literature shows contradictory data, the findings of other studies lead us to hypothesize that supplementing with beetroot juice could mitigate the ergolytic effects of hypoxia on cardiorespiratory endurance in athletes. It cannot be stated that the combination of beetroot juice with other supplements has a positive or negative effect on cardiorespiratory endurance, but it is possible that the effects of supplementation with beetroot juice can be undermined by interaction with other supplements such as caffeine.

Full Text Available Background. Angiofibromas are histologically benign vascular tumors, originating from the nasopharynx, near by the area of sphenopalatine foramen. These neoplasms occur typically in male adolescents. Reports of primary extranasopharyngeal angiofibromas have appeared sporadically in the literature in English. We present the first case of an elderly woman with tumor arising from the middle turbinate, diagnosed as angiofibroma. Case report. A 63-year-old female presented with left-sided nasal obstruction and epistaxis. Endoscopic evaluation revealed a polypoid mass arising from the anteroinferior portion of the left middle turbinate. Computed tomography (CT scan showed a soft-tissue opacity that filled the anterior part of the left nasal cavity. After the endoscopic excision of the mass, postoperative pathohistological and immunohistochemical analysis confirmed the diagnosis of an angiofibroma. Two years later, the patient was free of symptoms and without endoscopic evidence of recurrence. Conclusion. Extranasopharyngeal angiofibromas arising from the nasal cavity are extremely rare tumors. Immunohistochemical analysis is very important in all doubtful cases, especially in those with atypical location.

The aim of the study was to explore pre-competition training practices of elite endurance runners. Training details from elite British middle distance (MD; 800 m and 1500 m), long distance (LD; 3000 m steeplechase to 10,000 m) and marathon (MAR) runners were collected by survey for 7 days in a regular training (RT) phase and throughout a pre-competition taper. Taper duration was [median (interquartile range)] 6 (3) days in MD, 6 (1) days in LD and 14 (8) days in MAR runners. Continuous running volume was reduced to 70 (16)%, 71 (24)% and 53 (12)% of regular levels in MD, LD and MAR runners, respectively (P training (MD; 53 (45)%, LD; 67 (23)%, MAR; 64 (34)%, P training intensity was above race speed in LD and MAR runners (112 (27)% and 114 (3)%, respectively, P training undertaken prior to the taper in elite endurance runners is predictive of the tapering strategy implemented before competition.

Obviously, he wasn't thinking of his slaves. An attempt to remedy his negligence by considering this popular definition of eighteenth-century womanhood in relation to the females he forgot reveals this highly restrictive code to be exclusionary as well, for the difficulty of figuring out how brown or black skin can be "fair" suggests that a bondwoman in the New World was not, according to dominant ideology, a woman. Slavery made nonsense of female gender in the case of those whose labor allo wed white society its definition. A contemporary observer reveals just how thorough was the distinction between white womanly passivity and whatever unnamed oblivion was left to black females: "The labor of the slave thus becomes the substitute for that of the woman" (Smith 1980:70; Dew 1970 [1832]:36.

David Herbert Lawrence is one of the greatest novelists in the 20th century. In his novels, he portrays various types of women characters. Ursula Brangwen is a quintessential modern woman in The Rainbow and she shows the important characteris-tics of the western modern women. Being different from the traditional women, She is a rebelling woman and does not want to be bounded by conventions. She dares to condemn the religion, the Education system and the democracy. What's more, she pur-sues knowledge and freedom and strives for the value of self-realization, independence and individualism.

IDIOPATHIC INTRACRANIAL HYPERTENSION IN A WOMAN WITH SCHIZOPHRENIA

2012-02-01

Full Text Available Idiopathic intracranial hypertension (IIH or benign intracranial hypertension is a neurological syndrome characterized by elevated intracranial pressure. This uncommon disorder occurs primarily in obese women aged 10 to 50 years, sometimes in association with endocrine and metabolic dysfunction, with systemic diseases or when treated with multiple medications. We describe a case of IIH in a 43-year-old woman with schizophrenia treated with risperidone, demonstrating a typical clinical picture of benign intracranial hypertension. For the 5 years of treatment with risperidone she put on 35 kg in total (BMI> 35; for the last 2-3 months she began to complain of visual obscurations, nausea with vomiting. Ophthalmoscopy revealed bilateral asymmetric papilledema (OD>OS. Magnetic resonance imaging was normal, intracranial pressure was elevated IIH was diagnosed. Risperidone was discontinued and replaced with Seroquel 200 mg daily. Treatment with furosemide and mannitol 10 % was initiated. Papilledema resolved completely over the next 2 months. The patient was followed-up for four years after risperidone withdrawal. Weight loss of 28 kg was noted for four years. There were no relapses of headache, nausea, visual obscuration. Ophthalmologic examination revealed no papilledema.We suggest that prolonged use of antipsychotics, such as risperidone, should require proper surveillance for possible development of IIH and routine ophthalmologic examinations should be performed.

Endurance Exercise Mobilizes Developmentally Early Stem Cells into Peripheral Blood and Increases Their Number in Bone Marrow: Implications for Tissue Regeneration

Directory of Open Access Journals (Sweden)

Krzysztof Marycz

2016-01-01

Full Text Available Endurance exercise has been reported to increase the number of circulating hematopoietic stem/progenitor cells (HSPCs in peripheral blood (PB as well as in bone marrow (BM. We therefore became interested in whether endurance exercise has the same effect on very small embryonic-like stem cells (VSELs, which have been described as a population of developmentally early stem cells residing in BM. Mice were run daily for 1 hour on a treadmill for periods of 5 days or 5 weeks. Human volunteers had trained in long-distance running for one year, six times per week. FACS-based analyses and RT-PCR of murine and human VSELs and HSPCs from collected bone marrow and peripheral blood were performed. We observed that endurance exercise increased the number of VSELs circulating in PB and residing in BM. In parallel, we observed an increase in the number of HSPCs. These observations were subsequently confirmed in young athletes, who showed an increase in circulating VSELs and HSPCs after intensive running exercise. We provide for the first time evidence that endurance exercise may have beneficial effects on the expansion of developmentally early stem cells. We hypothesize that these circulating stem cells are involved in repairing minor exercise-related tissue and organ injuries.

Full Text Available The aim of the present study was to determine the effects of three weeks of hyperbaric oxygen (HBO2 training on oxidative stress markers and endurance performance in young soccer players. Participants (18.6±1.6 years were randomized into hyperbaric-hyperoxic (HH training (n=6 and normobaric normoxic (NN training (n=6 groups. Immediately before and after the 5th, 10th, and 15th training sessions, plasma oxidative stress markers (lipid hydroperoxides and uric acid, plasma antioxidant capacity (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid [TROLOX], arterial blood gases, acid-base balance, bases excess (BE, and blood lactate analyses were performed. Before and after intervention, maximal oxygen uptake (VO2max and peak power output (PPO were determined. Neither HH nor NN experienced significant changes on oxidative stress markers or antioxidant capacity during intervention. VO2max and PPO were improved (moderate effect size after HH training. The results suggest that HBO2 endurance training does not increase oxidative stress markers and improves endurance performance in young soccer players. Our findings warrant future investigation to corroborate that HBO2 endurance training could be a potential training approach for highly competitive young soccer players.

Katayama, K; Shimoda, M; Maeda, J; Takemiya, T

1998-10-01

The purpose of this study was to clarify whether peripheral vascular response to alteration of transmural pressure is changed by endurance exercise training. The healthy male subjects (training group; n = 6) performed endurance exercise training that consisted of cycle ergometer exercise 5 d.week-1 and 30 min.d-1 for a period of 8 weeks. Changes in the peripheral vascular response to alteration of transmural pressure in the human finger were measured by a differential digital photoplethysmogram (DeltaDPG) and blood pressure during passive movement of the arm to different vertical hand positions relative to heart level. Following 8 weeks of endurance training, percent changes in DeltaDPG from heart level in the training group increased significantly (mean +/- SD, -48.1 +/- 7. 3 to -58.7 +/- 9.3% at the lowered position, 46.1 +/- 13.4 to 84.6 +/- 8.8% at the elevated position, ppressure, also significantly changed in the training group over the 8 weeks (5.6 +/- 1.3 to 2.7 +/- 1.6 mV. V-1.s-1.mmHg-1 at the lowered position, 30.0 +/- 12.4 to 54.4 +/- 18. 9 mV.V-1.s-1.mmHg-1 at the elevated position ). Maximal oxygen uptake (V.O2 max) was significantly increased in the training group. On the other hand, the control group (n = 6) showed no significant changes in all parameters for 8 weeks. Therefore these results suggest that endurance exercise training induces an increase in peripheral vascular response to alteration of transmural pressure in the human finger.

What is the central question of this study? The main aim of the present study was to determine the effect of prolonged moderate-intensity endurance training on the endothelial glycocalyx layer integrity in relationship to the training-induced changes in oxidative stress and antioxidant defence in humans. What is the main finding and its importance? We have shown, for the first time, a protective effect of prolonged moderate-intensity endurance training on endothelial glycocalyx layer integrity, as judged by significantly lower basal and end-exercise serum concentrations of glycocalyx damage markers, i.e. syndecan-1 and heparan sulfate, accompanied by attenuation of oxidative stress and enhancement of antioxidant defence after training in previously untrained healthy young men. In this study, we evaluated the effect of 20 weeks of moderate-intensity endurance training (ET) on the endothelial glycocalyx layer integrity in relationship to the training-induced changes in antioxidant defence. Eleven healthy young, untrained men performed an incremental cycling exercise bout until exhaustion before and after 20 weeks of ET. Endurance training consisted of 40 min sessions, mainly of moderate intensity (∼50% of maximal oxygen uptake), performed four times per week. Venous blood samples were taken at rest and at the end of the maximal exercise test. Muscle biopsies from vastus lateralis were taken before and after the training. Endurance training resulted in a significant increase in physical capacity (P  0.05). Moderate-intensity ET exerts a pronounced protective effect on endothelial glycocalyx integrity at rest and during exercise, probably through an improvement of antioxidant defence that may represent the vasoprotective mechanisms highly responsive to moderate-intensity endurance training. © 2016 The Authors.

Spontaneous orgasm triggered from inside the foot has so far not been reported in medical literature. The study aims to report orgasmic feelings in the left foot of a woman. A woman presented with complaints of undesired orgasmic sensations originating in her left foot. In-depth interview, physical examination, sensory testing, magnetic resonance imaging (MRI-scan), electromyography (EMG), transcutaneous electrical nerve stimulation (TENS), and blockade of the left S1 dorsal root ganglion were performed. The main outcomes are description of this clinical syndrome, results of TENS application, and S1 dorsal root ganglion blockade. Subtle attenuation of sensory amplitudes of the left suralis, and the left medial and lateral plantar nerve tracts was found at EMG. MRI-scan disclosed no foot abnormalities. TENS at the left metatarso-phalangeal joint-III of the left foot elicited an instant orgasmic sensation that radiated from plantar toward the vagina. TENS applied to the left side of the vagina elicited an orgasm that radiated to the left foot. Diagnostic blockade of the left S1 dorsal root ganglion with 0.8 mL bupivacaine 0.25 mg attenuated the frequency and intensity of orgasmic sensation in the left foot with 50% and 80%, respectively. Additional therapeutic blockade of the same ganglion with 0.8 mL bupivacaine 0.50 mg combined with pulsed radiofrequency treatment resulted in a complete disappearance of the foot-induced orgasmic sensations. Foot orgasm syndrome (FOS) is descibed in a woman. Blockade of the left S1 dorsal root ganglion alleviated FOS. It is hypothesized that FOS, occurring 1.5 years after an intensive care emergency, was caused by partial nerve regeneration (axonotmesis), after which afferent (C-fiber) information from a small reinnervated skin area of the left foot and afferent somatic and autonomous (visceral) information from the vagina on at least S1 spinal level is misinterpreted by the brain as being solely information originating from

The incidence of an adenoid cystic carcinoma on major salivary glands is low, constituting only about 10% to 15% of all parotid malignancies. Cases of delayed metastasis have been reported, but reports of specific renal involvement have not been extensively found. We present the case of a 21-year-old woman with a left renal metastasis from an adenoid cystic carcinoma of the parotid gland that had been surgically treated 7 years previously. The patient underwent successful left radical nephrectomy. During follow-up, the patient developed pulmonary nodules that were metastatic adenoid cystic carcinoma and were surgically excised. At last follow-up, the patient was doing well with no evidence of disease.

This report presents the pressure drop, vibration and endurance test results for IR rig for RI production which were desigened and fabricated by KAERI. From the pressure drop test results, it is noted that the flow rate through the IR rig corresponding to the pressure drop of 200 kPa is measured to be about 3.12 kg/sec. Vibration frequency for the IR rig ranges from 13 to 17 Hz. RMS(Root Mean Square) displacement for the IR rig is less than 30 μm, and the maximum displacement is less than 110μm. These experimental results show that the design criteria of IR rig meet the HANARO limit conditions. Endurance test results show that the appreciable fretting wear for the IR rig does not occur, however tiny trace of wear between contact points is observed

Survival of the Fittest: Why Terrorist Groups Endure

Directory of Open Access Journals (Sweden)

Joseph K. Young

2014-04-01

Full Text Available Why do terrorist groups endure? This question is relevant to scholars and policy makers alike. In the past, this issue was not been addressed in a systematic fashion. Recent work investigates this question using data on transnational groups and finds that factors associated with the home country can influence the duration the group endures. Applying the theory of outbidding to terrorist group survival, we argue that strategic competition among groups predicts group duration. Using the Global Terrorism Database, we develop a dataset using the terrorist group as the unit of analysis to model the duration of group activity and thus include the largest sample of groups yet. Controlling for previous explanations of both group duration and terrorism, we find a robust effect for the impact that group competition has on terrorist group survival.

Handgrip and general muscular strength and endurance during prolonged bedrest with isometric and isotonic leg exercise training

Science.gov (United States)

Greenleaf, J. E.; Starr, J. C.; Van Beaumont, W.; Convertino, V. A.

1983-01-01

Measurements of maximal grip strength and endurance at 40 percent max strength were obtained for 7 men 19-21 years of age, 1-2 days before and on the first recovery day during three 2-week bedrest (BR) periods, each separated by a 3-week ambulatory recovery period. The subjects performed isometric exercise (IME) for 1 hr/day, isotonic exercise (ITE) for 1 hr/day, and no exercise (NOE) in the three BR periods. It was found that the mean maximal grip strength was unchanged after all three BR periods. Mean grip endurance was found to be unchanged after IME and ITE training, but was significantly reduced after NOE. These results indicate that IME and ITE training during BR do not increase or decrease maximal grip strength, alghough they prevent loss of grip endurance, while the maximal strength of all other major muscle groups decreases in proportion to the length of BR to 70 days. The maximal strength reduction of the large muscle groups was found to be about twice that of the small muscle groups during BR. In addition, it is shown that changes in maximal strength after spaceflight, BR, or water immersion deconditioning cannot be predicted from changes in submaximal or maximal oxygen uptake values.

Harriet Brooks: Canada's First Woman Physicist

Rayner-Canham, Geoffrey

2004-03-01

During those early halcyon days of the study of radioactivity, one young Canadian woman, Harriet Brooks, joined Ernest Rutherford's group as his first research student. Later, she joined J.J. Thomson's group in Cambridge and, finally, Marie Curie's group in Paris. During her short research career, she made several important contributions to science. She investigated the nature of 'emanation' from radium; discovered that radioactive substances could undergo successive decay; and first reported the recoil of the radioactive atom. Much of this research was published under her name alone though Rutherford made extensive reference to her discoveries in his Bakerian lecture of 1904. Brooks life is of interest not only in what she accomplished, but also in the challenges she faced as a pioneering woman scientist in the early part of the twentieth century. In the presentation we will blend the account of her life and work with the societal context. This work was accomplished jointly with Marelene F. Rayner-Canham.

This article is a systhematic literature review including the period from 1994 to 2009, whose objective was to discuss the aged woman's vulnerability in relation to Acquired Imunodeficiency Syndrome (Aids). The search for scientific texts was accomplished in the following databases: Biblioteca Virtual em Saúde, Scientific Eletronic Library Online (SciELO), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Medical Literature Analysis and Retrieval System Online (MEDLINE). The descriptors used were vulnerability, woman and Aids. Eighteen texts were analyzed, including articles in scientific journals, thesis and dissertations. As a conclusion, it was noted that aged women and vulnerability to Aids are directly related, through gender characteristics including submission and that were built historical and socially. We consider as fundamental the development of studies which may generate publications accessible to women, in order to help them see themselves as persons vulnerable to Aids contagion just for being women.

Larsen, Christian; Jensen, Mogens Pfeiffer

2014-06-16

A 35-year-old woman was acutely hospitalized with oedema of the upper limbs, reduced force, severe movement reduction and muscle pain in both upper extremities. Her symptoms started after three days of intense exercise doing kayaking and a lot of pull-ups in crossfit. Rhabdomyolysis is a syndrome, characterized by muscle necrosis. Usually there is a marked elevation of creatine kinase (CK) concentration with symptoms as described and myoglobinuria (dark coloured urine). After hard muscular work there will often be asymptomatic, but significant elevations in CK concentration, and in rare cases life-threatening rhabdomyolysis with electrolyte imbalances and acute kidney failure.

Although hyperthyroidism arising from primary thyroid disease is rare in pregnancy, transient gestational hyperthyroidism is not uncommon. This condition can be associated with hyperemesis gravidarum (HG), and Wernicke's encephalopathy. We present the case of a woman with toxic nodular goiter complicating HG-associated Wernicke's encephalopathy. A 38-year-old Caucasian woman, who had received a diagnosis of hyperthyroidism and HG early in her pregnancy, had intrauterine fetal death at Week 16 of gestation. One day after undergoing therapeutic abortion, she was admitted to our clinic with persistent thyrotoxicosis, nausea, and vomiting. A toxic thyroid nodule was detected. She was given antithyroid medication, total parenteral nutrition. On Day 10 of hospitalization, she developed ataxia, aphasia, and somnolence. Cranial magnetic resonance imaging showed increased bilateral thalamic signalization. She was given a diagnosis of Wernicke's metabolic encephalopathy, for which she received thiamine and multivitamin preparations. She responded dramatically on the second day of thiamine therapy. Her consciousness improved rapidly and she began to speak. Her muscle tone was slightly weak and she had paresthesias in both legs. Absorption of thiamine may be particularly impaired in pregnant women with hyperemesis and hyperthyroid disease. Wernicke's encephalopathy should be considered in hyperthyroid women with HG who develop neurological abnormalities.

Full Text Available The effects of endurance training on endurance performance characteristics and cardiac autonomic modulation during night sleep were investigated during two 4-week training periods. After the first 4-week training period (3 x 40 min per week, at 75% of HRR the subjects were divided into HIGH group (n = 7, who performed three high-intensity endurance training sessions per week; and CONTROL group (n = 8 who did not change their training. An incremental treadmill test was performed before and after the two 4-weektraining periods. Furthermore, nocturnal RR-intervals were recorded after each training day. In the second 4-weektraining period HIGH group increased their V0Zmax (P = 0.005 more than CONTROL group. At the same time, nocturnal HR decreased (P = 0.039 and high-frequency power (HFP increased (P = 0.003 in HIGH group while no changes were observed in CONTROL group. Furthermore, a correlation was observed between the changes in nocturnal HFP and changes in V0Zmax during the second 4-week training period (r = 0.90, P < 0.001. The present study showed that the increased HFP is related to improved VO2max in sedentary subjects suggesting that nocturnal HFP can provide a useful method in monitoring individual responses to endurance training.

This study collected data on the maximum anterior and posterior tongue strength and endurance in 420 healthy Belgians across the adult life span to explore the influence of age, sex, bulb position, visual feedback, and order of testing. Measures were obtained using the Iowa Oral Performance Instrument (IOPI). Older participants (more than 70 years old) demonstrated significantly lower strength than younger persons at the anterior and the posterior tongue. Endurance remains stable throughout the major part of life. Gender influence remains significant but minor throughout life, with males showing higher pressures and longer endurance. The anterior part of the tongue has both higher strength and longer endurance than the posterior part. Mean maximum tongue pressures in this European population seem to be lower than American values and are closer to Asian results. The normative data can be used for objective assessment of tongue weakness and subsequent therapy planning of dysphagic patients.

Deok-Jin Lee

2011-06-01

Full Text Available This paper presents an effective hybrid control approach for building stable wireless sensor networks between heterogeneous unmanned vehicles using long‐ endurance aerial robotic vehicles. For optimal deployment of the aerial vehicles in communication networks, a gradient climbing based self‐estimating control algorithm is utilized to locate the aerial platforms to maintain maximum communication throughputs between distributed multiple nodes. The autonomous aerial robots, which function as communication relay nodes, extract and harvest thermal energy from the atmospheric environment to improve their flight endurance within specified communication coverage areas. The rapidly‐deployable sensor networks with the high‐endurance aerial vehicles can be used for various application areas including environment monitoring, surveillance, tracking, and decision‐making support. Flight test and simulation studies are conducted to evaluate the effectiveness of the proposed hybrid control technique for robust communication networks.

A 37-year-old woman presenting with impaired visual function during antituberculosis drug therapy: a case report

Full Text Available Abstract Introduction Combination antituberculosis drug therapy remains the mainstay of treating tuberculosis. Unfortunately, antituberculosis drugs produce side effects including (toxic impaired visual function, which may be irreversible. We report a case of antituberculosis-drug-induced impaired visual function that was reversed following early detection and attention. Case presentation A 37-year-old Yoruba woman, weighing 48 kg, presented to our facility with impaired visual functions and mild sensory polyneuropathy in about the fourth month of antituberculosis treatment. Her therapy comprised ethambutol 825 mg, isoniazid 225 mg, rifampicin 450 mg, and pyrazinamide 1200 mg. Her visual acuity was 6/60 in her right eye and 1/60 in her left eye. She had sluggish pupils, red-green dyschromatopsia, hyperemic optic discs and central visual field defects. Her intraocular pressure was 14 mmHg. Her liver and kidney functions were essentially normal. Screening for human immunodeficiency virus was not reactive. Her impaired visual function improved following prompt diagnosis and attention, including the discontinuation of medication. Conclusions The ethambutol and isoniazid in antituberculosis medication are notorious for causing impaired visual function. The diagnosis of ocular toxicity from antituberculosis drugs should never be delayed, and should be possible with the patient's history and simple but basic eye examinations and tests. Tight weight-based antituberculosis therapy, routine peri-therapy visual function monitoring towards early detection of impaired function, and prompt attention will reduce avoidable ocular morbidity.

Neuromuscular function and fatigue resistance of the plantar flexors following short-term cycling endurance training

2015-05-01

Full Text Available Previously published studies on the effect of short-term endurance training on the neuromuscular function of the plantar flexors have shown that the H-reflex elicited at rest and during weak voluntary contractions was increased following the training regime. However, these studies did not test H-reflex modulation during isometric maximum voluntary contraction (iMVC and did not incorporate a control group in their study design to compare the results of the endurance training group to individuals without the endurance training stimulus. Therefore, this randomized controlled study was directed to investigate the neuromuscular function of the plantar flexors at rest and during iMVC before and after eight weeks of cycling endurance training. Twenty-two young adults were randomly assigned to an intervention group and a control group. During neuromuscular testing, rate of torque development, isometric maximum voluntary torque and muscle activation were measured. Triceps surae muscle activation and tibialis anterior muscle co-activation were assessed by normalized root mean square of the EMG signal during the initial phase of contraction (0-100, 100-200 ms and isometric maximum voluntary contraction of the plantar flexors. Furthermore, evoked spinal reflex responses of the soleus muscle (H-reflex evoked at rest and during iMVC, V-wave, peak twitch torques induced by electrical stimulation of the posterior tibial nerve at rest and fatigue resistance were evaluated. The results indicate that the endurance training did not lead to a significant change in any variable of interest. Data of the present study conflict with the outcome of previously published studies that have found an increase in H-reflex excitability after endurance training. However, these studies had not included a control group in their study design as was the case here. It is concluded that short-term cycling endurance training does not necessarily enhance H-reflex responses and fatigue

An enduring nuclear fuel cycle is an essential part of sustainable consumption, the process whereby world's riches are consumed in a responsible manner so that future generations can continue to enjoy at least some of them. In many countries, the goal of sustainable development has focused attention on the benefits of nuclear technologies. However, sustenance of the nuclear fuel cycle is dependent on sensible management of all the resources of the fuel cycle, including energy, spent fuels, and all of its side streams. The nuclear fuel cycle for energy production has suffered many traumas since the mid seventies. The common basis of technologies producing nuclear explosives and consumable nuclear energy has been a preoccupation for some, predicament for others, and a perception problem for many. It is essential to reestablish a reliable back end of the nuclear fuel cycle that can sustain the resource requirements of an enduring full cycle. This paper identifies some pragmatic steps necessary to reverse the trend and to maintain a necessary fuel cycle option for the future

We report a right-handed 34-year-old woman with diffuse muscle atrophy. The patient was a full-term infant of uneventful delivery, however, motor milestones were delayed in that neck control was obtained at 10 months of the age and she started to walk unassisted at 2 years of the age. Mental development was normal. She was unable to run with her mates at her kindergarten and she required a handrail when she walk up the stairs. She could not close her mouth completely at the primary school. She was unable to use a straw as a middle school pupil. Recently, she noted difficulty in raising her head from the supine position, and has become unable to walk a long distance. She was admitted to our hospital in September 17, 1994 when she was 34-year-old. On admission, general physical examination revealed that she looked slender weighing 38 kg with 149.5 cm height. She showed a high arched palate, slight scoliosis, and pes equinus. Otherwise general physical examination was unremarkable. Upon neurologic examination, she was alert and well oriented. Cranial nerves were unremarkable except for bilateral facial atrophy and moderate weakness. Her voice was of nasal quality, and swallowing was slightly difficult. No atrophy was noted in the sternocleidomastoid muscle. She showed waddling gait and positive Gowers' sign. Diffuse muscle atrophy was noted and mild to moderate weakness was presented more in the proximal part in both upper and lower extremities, however, deltoid muscles retained normal power. No ataxia was noted. All the deep tendon reflexes were lost. Sensation was intact. Routine laboratory examination was unremarkable. Serum CK was 56 IU/l. Electromyography revealed myogenic changes in the deltoid, biceps, and quadriceps muscles. A diagnostic biopsy was performed in the left biceps brachii muscle. The patient was discussed in the neurologic CPC, and the chief discussant arrived at the conclusion that the patient had nemaline myopathy. Opinions were divided among

Feederism in a woman.

Science.gov (United States)

Terry, Lesley L; Vasey, Paul L

2011-06-01

Feederism is a fat fetish subculture in which individuals eroticize weight gain and feeding. Feeders are individuals who claim to become sexually aroused by feeding their partners and encouraging them to gain weight. Conversely, Feedees are individuals who claim to become sexually aroused by eating, being fed, and the idea or act of gaining weight. Very little is known about this population. This report describes a woman who self-identified as a Feedee. It is unclear, at present, whether female Feederism represents a unique paraphilia or a thematic variation of morphophilia or sexual masochism.

ENDURANCE TRAINING AND GLUTATHIONE-DEPENDENT ANTIOXIDANT DEFENSE MECHANISM IN HEART OF THE DIABETIC RATS

Directory of Open Access Journals (Sweden)

Mustafa Atalay

2003-06-01

Full Text Available Regular physical exercise beneficially influences cardiac antioxidant defenses in normal rats. The aim of this study was to test whether endurance training can strengthen glutathione-dependent antioxidant defense mechanism and decrease lipid peroxidation in heart of the streptozotocin-induced diabetic rats. Redox status of glutathione in blood of diabetic rats in response to training and acute exercise was also examined. Eight weeks of treadmill training increased the endurance in streptozotocin-induced diabetic rats. It did not affect glutathione level in heart tissue at rest and also after exercise. On the other hand, endurance training decreased glutathione peroxidase activity in heart, while glutathione reductase and glutathione S-transferase activities were not affected either by acute exhaustive exercise or endurance training. Reduced and oxidized glutathione levels in blood were not affected by either training or acute exercise. Conjugated dienes levels in heart tissue were increased by acute exhaustive exercise and also 8 weeks treadmill training. Longer duration of exhaustion in trained group may have contributed to the increased conjugated dienes levels in heart after acute exercise. Our results suggest that endurance type exercise may make heart more susceptible to oxidative stress. Therefore it may be wise to combine aerobic exercise with insulin treatment to prevent its adverse effects on antioxidant defense in heart in patients with diabetes mellitus

2010-03-01

The effects of endurance training on endurance performance characteristics and cardiac autonomic modulation during night sleep were investigated. Twenty-four sedentary subjects trained over four weeks two hours per week at an average running intensity of 76+/-4% of their heart rate reserve. The R to R ECG-intervals were recorded and heart rate variability indices including high frequency power (HFP) were calculated for the nights following the training days every week. The subjects were divided into responders and non-responders according to the improvements in the maximal velocity of the incremental treadmill test (v(max)). The responders improved their v(max) by 10.9+/-46 % (p < 0.001) while no changes were observed in the non-responders (1.6+/-3.0%), although there were no differences in any training load variables between the groups. In the responders nocturnal HFP was significantly higher during the fourth training week compared to the first training week (p=0.036). Furthermore, a significant correlation was observed between the change in v(max) and the change in nocturnal HFP (r=0.482, p=0.042). It was concluded that after similar training, an increase in cardiac vagal modulation was related to improved v(max) in the sedentary subjects. Georg Thieme Verlag KG Stuttgart.New York.

García-Pinillos, F, Soto-Hermoso, VM, and Latorre-Román, PÁ. Do running kinematic characteristics change over a typical HIIT for endurance runners?. J Strength Cond Res 30(10): 2907-2917, 2016-The purpose of this study was to describe kinematic changes that occur during a common high-intensity intermittent training (HIIT) session for endurance runners. Twenty-eight male endurance runners participated in this study. A high-speed camera was used to measure sagittal-plane kinematics at the first and the last run during a HIIT (4 × 3 × 400 m). The dependent variables were spatial-temporal variables, joint angles during support and swing, and foot strike pattern. Physiological variables, rate of perceived exertion, and athletic performance were also recorded. No significant changes (p ≥ 0.05) in kinematic variables were found during the HIIT session. Two cluster analyses were performed, according to the average running pace-faster vs. slower, and according to exhaustion level reached-exhausted group vs. nonexhausted group (NEG). At first run, no significant differences were found between groups. As for the changes induced by the running protocol, significant differences (p ≤ 0.05) were found between faster and slower athletes at toe-off in θhip and θknee, whereas some changes were found in NEG in θhip during toe-off (+4.3°) and θknee at toe-off (-5.2°) during swing. The results show that a common HIIT session for endurance runners did not consistently or substantially perturb the running kinematics of trained male runners. Additionally, although some differences between groups have been found, neither athletic performance nor exhaustion level reached seems to be determinant in the kinematic response during a HIIT, at least for this group of moderately trained endurance runners.

There is concern over the effect of training on heart function of athletes as recorded by 12-lead electrocardiography (ECG). Although ECG abnormalities with respect to ethnic origin of black athletes from the Caribbean, West Africa and East Africa have been reported, black athletes from southern Africa, specifically participating in different sports, have never been investigated before. The purpose of this study was to analyze the ECG patterns in South African students of Zulu descent, who represented our university in boxing (endurance modality) and body building (resistance modality) at a regional level. Fifteen subjects each were assigned to an endurance (E), resistance (R) or control (C) group, respectively. ECG patterns were recorded with a 12-lead ECG. Our subjects indicated no significant differences in ECG patterns in relation to whether they participate in strength or endurance related sport. However, 80% of the endurance group and 67% of the resistance displayed ECG criteria indicative of left ventricular hypertrophy (LVH), group E displays higher R5/S1-wave voltages (E=43.3 mm; R=36.8 mm; C=37.1 mm) as well distinctly abnormal ECG patterns (E=87%; R=73%; C=53%), raising clinical suspicion of structural heart disease. Our cohort presented with non-significant, marked ST-segment elevation (53% of both the E and R groups) and inverted T-waves in 27% of the E group. Similar to findings in other ethnic Africans, a large proportion of our Zulu study population displayed ECG criteria indicative of LVH on the evidence of a marked increase of R5/S1-wave voltage and ST/T-segment changes with no differences in relation to whether they participate in strength or endurance related sport.

Increase in swimming endurance capacity of mice by capsaicin-induced adrenal catecholamine secretion.

Increase in endurance swimming capacity caused by capsaicin (CAP), a pungent component of red pepper, -induced increase of fat metabolism in mice was investigated using an adjustable-current water pool. The mice administered CAP via a stomach tube, showed longer swimming time until exhaustion than the control group of mice, in a dose-dependent manner. The maximal effect was observed at a dose of 10 mg/kg while more than 15 mg/kg had no effect. The increase of endurance was observed only when CAP was administered two hours before swimming. After the administration of CAP, the serum glucose concentration rapidly increased and then decreased within 60 min, while the concentration of serum-free fatty acids gradually increased through 3 hours. The residual glycogen concentration of the gastrocnemius muscle after 30 min of swimming was significantly higher in the CAP-administered mice than in control mice, suggesting that use of the serum free fatty acids spared muscle glycogen consumption. The serum adrenaline concentration significantly increased with twin peaks at 30 min and two hours after administration of CAP. An experiment using adrenalectomized mice was done to confirm that the effect of CAP is due to increased energy metabolism through the secretion of adrenaline from the adrenal gland. The swimming endurance capacity of the adrenalectomized mice was not increased by CAP administration, although adrenaline injection induced a 58% increase in the endurance time. These results suggest that the increase of swimming endurance induced by CAP in mice is caused by an increase in fatty acid utilization due to CAP-induced adrenal catecholamine secretion.

Endurance performance depends on the integration of several phenotypic traits influenced by multiple environmental and genetic factors. Objectives of the study were: (1) to examine the genotypic frequencies of the ACE I/D, ACTN3 R577X polymorphisms and endurance performance-related phenotypes, (2) to evaluate the dynamics of endurance performance parameters during a 5-year period in relation to ACE I/D and ACTN3 R577X genotypes in Estonian young skiers. Determination of VO2peak was performed in 58 skiers aged 15-19 years (41 males, 17 females) during a 5-year period. The control group consisted of 322 healthy non-athletic subjects (145 males, 177 females). The study groups were genotyped for the ACE I/D and ACTN3 R577X variants. Frequencies of the ACE ID and ACTN3 RR genotypes were significantly higher (p = 0.047 and p = 0.003, respectively) and the RX genotype was lower (p = 0.008) in young male skiers compared with controls. A significant relationship was found between change (Δ) of training volume and ΔVO2peak (mL·kg(-1)·min(-1)) (r = 0.475, p = 0.002). No significant main effect was detected between VO2peak (mL·kg(-1)·min(-1)) dynamics (comparison with the previous age group data) and ACE I/D and ACTN3 R577X genotypes interactions (F = 0.571, p = 0.770 and F = 0.650 and p = 0.705, respectively) in all young skiers. Study results indicated a significantly higher frequency of the ACE ID and ACTN3 RR genotypes among Estonian young male skiers compared with the male control group. Significant genotype-related differences in dynamics of VO2peak during a 5-year period were not found. In the future, longitudinal research including different gene variants may contribute to a better understanding of the nature of endurance performance. Key pointsSignificantly higher prevalence of the ACE ID and the ACTN3 RR genotypes were found among Estonian young male skiers compared with the male control group, which may be an advantage for the explosive speed and power

Currently, at least 18,000 women die every year in Indonesia due to pregnancy or childbirth. It means that every half hour a woman dies due to pregnancy or childbirth. As a result, every year 36,000 children became orphans. The high maternal mortality rate was put Indonesia on top in ASEAN. The main causes of maternal mortality are high-risk pregnancy. Mothers who have diseases like high blood pressure, pre-eclampsia, diabetes, hyperthyroidism, and already over 40 years old and infectious diseases such as rubella, hepatitis and HIV can be factors that lead to high-risk pregnancy. This paper will discuss the development of a blood pressure monitoring device that is suitable for pregnant women. It is based on convenience for pregnant women to get the equipment that is flexible with her presence. Results indicate that the equipment is in use daily support for pregnant women therefore, one of the causes of maternal mortality can be detected earlier.

Purpose The purpose of the current study was to investigate the effects of adding strength training to normal endurance training on running performance and running economy in well-trained female athletes. We hypothesized that the added strength training would improve performance and running economy through altered stiffness of the muscle-tendon complex of leg extensors. Methods Nineteen female endurance athletes [maximal oxygen consumption (VO2max): 53±3 ml∙kg-1∙min-1, 5.8 h weekly endurance training] were randomly assigned to either normal endurance training (E, n = 8) or normal endurance training combined with strength training (E+S, n = 11). The strength training consisted of four leg exercises [3 x 4–10 repetition maximum (RM)], twice a week for 11 weeks. Muscle strength, 40 min all-out running distance, running performance determinants and patellar tendon stiffness were measured before and after the intervention. Results E+S increased 1RM in leg exercises (40 ± 15%) and maximal jumping height in counter movement jump (6 ± 6%) and squat jump (9 ± 7%, p running economy, fractional utilization of VO2max or VO2max. There were also no change in running distance during a 40 min all-out running test in neither of the groups. Conclusion Adding heavy strength training to endurance training did not affect 40 min all-out running performance or running economy compared to endurance training only. PMID:26953893

Researchers have retrospectively analyzed the training intensity distribution (TID) of nationally and internationally competitive athletes in different endurance disciplines to determine the optimal volume and intensity for maximal adaptation. The majority of studies present a “pyramidal” TID with a high proportion of high volume, low intensity training (HVLIT). Some world-class athletes appear to adopt a so-called “polarized” TID (i.e., significant % of HVLIT and high-intensity training) during certain phases of the season. However, emerging prospective randomized controlled studies have demonstrated superior responses of variables related to endurance when applying a polarized TID in well-trained and recreational individuals when compared with a TID that emphasizes HVLIT or threshold training. The aims of the present review are to: (1) summarize the main responses of retrospective and prospective studies exploring TID; (2) provide a systematic overview on TIDs during preparation, pre-competition, and competition phases in different endurance disciplines and performance levels; (3) address whether one TID has demonstrated greater efficacy than another; and (4) highlight research gaps in an effort to direct future scientific studies.

MODY diabetes includes rare familiar forms due to genetic mutations resulting in β-cell dysfunction. MODY 3 is due to mutations in the gene transcription factor HNF-1α, with diabetes diagnosis in adolescence or early adult life. Few data are available about MODY 3 in pregnancy. A 36-year-old Italian woman came to our unit at the 5th week of pregnancy. She was diagnosed with diabetes at 18 years, with negative autoimmunity and a strong familiarity for diabetes. She was treated with gliclazide and metformin. She had a previous pregnancy in which she was treated with insulin, giving birth at 38 weeks to a 3.210 kg baby girl, who showed neonatal hypoglycemia. We switched her to insulin treatment according to guidelines. We asked for genetic molecular testing, resulting in a HNF-1α gene mutation. A US examination at 7 weeks revealed a twin, bicorial, biamniotic pregnancy. At 37 weeks of gestation, she gave birth to two normal-weight baby girls; only one showed neonatal hypoglycemia and a genetic test revealed that she was affected by HNF-1α gene mutation. Subsequently, entire family of the woman was tested, showing that the father, the sister and the first daughter had the same HNF-1α mutation. A MODY 3 foetus needs a near-normal maternal glycemic control, because the exposure to intrauterine hyperglycemia can lead to an earlier age of diabetes onset. Neonatal hypoglycemia is generally observed in MODY 1 infants, but it is possible to hypothesize that some HNF-1α mutations could lead to a functionally impaired protein that might dysregulate HNF-4α expression determining hypoglycemia.

A will to youth: the woman's anti-aging elixir.

Science.gov (United States)

Smirnova, Michelle Hannah

2012-10-01

The logic and cultural myths that buttress the cosmeceutical industry construct the older woman as a victim of old age, part of an "at-risk" population who must monitor, treat and prevent any markers of old age. A content and discourse analysis of 124 advertisements from the US More magazine between 1998 and 2008, revealed three major themes working together to produce this civic duty: (1) the inclusion of scientific and medical authorities in order to define the cosmeceutical as a 'drug' curing a disease, (2) descriptions of the similarities (and differences) between the abilities of cosmeceuticals and cosmetic surgery to restore one's youth, and (3) the logic equating youth with beauty, femininity and power and older age with the absence of these qualities. Together these intersecting logics produce the "will to youth"-the imperative of the aging woman to promote her youthful appearance by any and all available means. Further, by using images and references to fantasies and traditional fairytales, cosmeceutical advertisements both promise and normalize expectations of eternal youth of the aging woman.

To examine the validity and reliability of a sports-specific endurance plank test for the evaluation of global core muscle function. Repeated-measures study. Laboratory environment. Twenty-eight male and eight female young athletes. Surface electromyography (sEMG) of selected trunk flexors and extensors, and an intervention of pre-fatigue core workout were applied for test validation. Intraclass correlation coefficient (ICC), coefficient of variation (CV), and the measurement bias ratio */÷ ratio limits of agreement (LOA) were calculated to assess reliability and measurement error. Test validity was shown by the sEMG of selected core muscles, which indicated >50% increase in muscle activation during the test; and the definite discrimination of the ∼30% reduction in global core muscle endurance subsequent to a pre-fatigue core workout. For test-retest reliability, when the first attempt of three repeated trials was considered as familiarisation, the ICC was 0.99 (95% CI: 0.98-0.99), CV was 2.0 ± 1.56% and the measurement bias ratio */÷ ratio LOA was 0.99 */÷ 1.07. The findings suggest that the sport-specific endurance plank test is a valid, reliable and practical method for assessing global core muscle endurance in athletes given that at least one familiarisation trial takes place prior to measurement.

Full Text Available Indonesian marriage states that marriage is physical and spiritual relationship between a man and a woman as husband and wife in order to create an eternal happy family based on the Almighty God. This definition reflects that the marriage in Indonesia must be between heterosexual couple. However, a question appears as to whether a man or a woman mentioned thereof is included a man and a woman who were, hermaphrodite, intersex, or nowadays known as person with Disorder of Sexual Development (DSD? The case of AH whereby his marriage is cancelled by the Supreme Court in 2014 for he is not considered as a man, is confirming that this question is important to value the capacity of a person to marry. This writing will apply normative research as well as literature research method upon the positive rules and regulations. The decisions of district courts upon the revision or change of gender and its legal basis will be analysed and be the topic of discussion. Comparison will be applied to compare the marriage requirements between Indonesian Law, Singapore Law and Hong Kong Law. The results of analyse and discussion will be the closure of the writing, as conclusions and advise, if any.

2007-04-01

Full Text Available Abstract Background Takotsubo cardiomyopathy is an acute cardiac syndrome characterized by transient LV regional wall motion abnormalities (with peculiar apical ballooning appearance, chest pain or dyspnea, ST-segment elevation and minor elevations of cardiac enzyme levels Case presentation A 68-year-old woman was admitted to the Emergency Department because of sudden onset chest pain occurred while transferring her daughter, who had earlier suffered a major seizure, to the hospital. The EKG showed sinus tachycardia with ST-segment elevation in leads V2–V3 and ST-segment depression in leads V5–V6, she was, thus, referred for emergency coronary angiography. A pre-procedural transthoracic echocardiogram revealed regional systolic dysfunction of the LV walls with hypokinesis of the mid-apical segments and hyperkinesis of the basal segments. Coronary angiography showed patent epicardial coronary arteries; LV angiography demonstrated the characteristic morphology of apical ballooning with hyperkinesis of the basal segments and hypokinesis of the mid-apical segments. The post-procedural course was uneventful; on day 5 after admission the echocardiogram revealed full recovery of apical and mid-ventricular regional wall-motion abnormalities. Conclusion Takotsubo cardiomyopathy is a relatively rare, unique entity that has only recently been widely appreciated. Acute stress has been indicated as a common trigger for the transient LV apical ballooning syndrome, especially in postmenopausal women. The present report is a typical example of stress-induced takotsubo cardiomyopathy in a Caucasian Italian postmenopausal woman.

A study on the data of the physique investigated in teenagers was carried out between Hong Kong and inland cities to compare their cardiopulmonary endurance and muscular fitness. Results revealed that cardiopulmonary endurance in school teenagers of both sex at different ages in inland cities was better than that in Hong Kong. Muscular strength and endurance of sports performance of teenagers, except for standing long jump, in Hong Kong were weaker than that in inland cities. It suggests that attention should be paid to the involvement of teenagers in physical education with the increase of people's living standard.

Highlights: • The scope of this paper is to apply solar energy to achieve the high-altitude long-endurance flight. • The equivalence of gravitational potential and rechargeable battery is discussed. • Four kinds of factors have been discussed to compare the two method of energy storage. • This work can provide some governing principles for the application of solar-powered aircraft. - Abstract: Applying solar energy is one of the most promising methods to achieve the aim of High-altitude Long-endurance (HALE) flight, and solar-powered aircraft is usually taken by the research groups to develop HALE aircraft. However, the crucial factor which constrains the solar-powered aircraft to achieve the aim of HALE is the problem how to fulfill the power requirement under weight constraint of rechargeable batteries. Motivated by the birds store energy from thermal by gaining height, the method of energy stored by gravitational potential for solar-powered aircraft have attracted great attentions in recent years. In order to make the method of energy stored in gravitational potential more practical in solar-powered aircraft, the equivalence of gravitational potential and rechargeable battery for aircraft on energy storage has been analyzed, and four kinds of factors are discussed in this paper: the duration of solar irradiation, the charging rate, the energy density of rechargeable battery and the initial altitude of aircraft. This work can provide some governing principles for the solar-powered aircraft to achieve the unlimited endurance flight, and the endurance performance of solar-powered aircraft may be greatly improved by the application of energy storage using gravitational potential

Evidence shows that regular physical exercise reduces physiological reactivity to psychosocial stress. However, previous research mainly focused on the effect of endurance exercise, with only a few studies looking at the effect of resistance exercise. The current study tested whether individuals who regularly participate in either endurance or resistance training differ from untrained individuals in adrenal and cardiovascular reactivity to psychosocial stress. Twelve endurance-trained men, 10 resistance-trained men, and 12 healthy but untrained men were exposed to a standardized psychosocial stressor, the Trier Social Stress Test. Measurements of heart rate, free salivary cortisol levels, and mood were obtained throughout the test and compared among the three groups. Overall, both endurance- and resistance-trained men had lower heart rate levels than untrained men, indicating higher cardiac performance of the trained groups. Trained men also exhibited lower heart rate responses to psychosocial stress compared with untrained men. There were no significant group differences in either cortisol responses or mood responses to the stressor. The heart rate results are consistent with previous studies indicating reduced cardiovascular reactivity to psychosocial stress in trained individuals. These findings suggest that long-term endurance and resistance trainings may be related to the same cardiovascular benefits, without exhibiting strong effects on the cortisol reactivity to stress.

We report a case of pulmonary inflammatory myofibroblastic tumor (IMT) showing aggressive and unusually rapid progression. A 27-year-old woman was admitted to the emergency room due to dry cough, fever and blood-tinged sputum that lasted one week. Initial chest radiograph and computed tomography scan revealed multifocal pulmonary nodules, which subsequently progressed into large necrotic masses within two months. She underwent a fine needle biopsy of the largest mass in the right middle lung zone which revealed inflammatory myofibroblastic cells consistent with IMT. The masses showed complete regression after six months of corticosteroid therapy. This unusual clinical manifestation could help explain the reactive inflammatory nature associated with IMTs

2012-05-01

Full Text Available We present a case of a 57-year-old woman who underwent surgery for the removal of an ovarian mass but subsequently experienced microangioathic hemolytic anemia post-operatively, associated with fevers, renal insufficiency, hypertension, and hemolysis. While her clinical situations was initially suspicious for thrombotic thrombocytopenic purpura (TTP, further sorting of clinical information led to other explanations of these findings, including a systemic inflammatory response. Multiple triggers of the coagulation system which can lead to a common pathway of hemostatic failure were considered, and specific criteria seen in disseminated intravascular coagulation (DIC, TTP, heparin-induced thrombocytopenia (HIT, catastrophic antiphospholipid anitbody syndrom (APS, all of which can seem to overlap when a physician is faced with distinguishing the diagnosis clinically. We propose a chronologic and strategic approach for the clinician to consider when approaching this diagnostic dilemma.

Full Text Available Background: Strenuous and endurance exercise training have been associated with morphological and functional heart remodeling. Two-dimensional speckle-tracking echocardiography (STE is a novel technique that allows an accurate quantification of global myocardium deformation. Our aim was to evaluate together left and right cardiac remodeling in different long-distance running athletes: marathon runners (42 km (M and endurance mountain runners (>300 Km (UT.Methods: A total of 92 athletes (70 males, 76% including 47 M [age 45 ± 7 years; training: 18 (9–53 years*days/week], 45 UT [age 42 ± 9, training: 30 (15–66 years*days/week] underwent conventional echocardiography and STE (Beyond Diogenes 2.0, AMID during the agonistic season.Results: Right ventricle (RV end-diastolic area (p = 0.026, fractional area changing (FAC (p = 0.008 and RV global longitudinal strain (GLS were significantly increasedin UT athletes. Furthermore, UT showed larger right atrium (RA volume (p = 0.03, reduced RA GLS and significantly increased RA global circumferential strain (GCS compared to M. After adjustment for age, sex, and HR as covariates, UT showed a reduced RA GLS (OR 0.907; CI 0.856–0.961 and increased RV FAC (OR 1.172; CI: 1.044–1.317 compared to M.Conclusion: Athletes enrolled in UT endurance activities showed RV and RA morphological and functional remodeling to increased preload in comparison with M runners characterized by increased RV FAC and reduced RA GLS. Follow-up studies are needed to better assess the long-term clinical impact of these modifications. 2D STE is a useful tool for investigating the deformation dynamic in different sports specialties.

Full Text Available At the sample of 80 handball cadet contestants aged between 16-17, there has been done an endurance testing in the discipline of running on a track of total of 12 and 6 minutes. The endurance was estimated in meters of the distance run. The aim of this task was to determine coorelation of the results in running on 12 and 6 minutes. The outcome is a total coorelation between the two. Running of the du- ration of 6 minutes is recommended for the trainer`s practice. Testing is more rational. With the application of the regressive analyses it has been determined that there is depenndance between running time and variables: weight, height and BMI

Full Text Available A conceptual design of an innovative test rig for endurance tests of ball screws is presented in this paper. The test rig layout is based on the power recirculating principle and it also allows to overtake the main critical issues of the ball screw endurance tests. Among these there are the high power required to make the test, the lengthy duration of the same and the high loads between the screw and the frame that holds it. The article describes the test rig designed scheme, the kinematic expedients to be adopted in order to obtain the required performance and functionality and the sizing procedure to choose the actuation system.

2005-01-01

The aim was to study whether aerobic fitness measured by a maximal endurance running test at adolescence predicts prevalence of hypertension or blood pressure levels in adulthood. From the 413 (197 slow runners and 216 fast runners) participating in a 2000-meter running test at adolescence in 1976 and responding to a health and fitness questionnaire in 2001, 29 subjects (15 very slow runners and 14 very fast runners) participated in a clinical follow-up study in 2001. Compared to those who were fast runners in adolescence, those who were slow runners tended to have higher age-adjusted risk of hypertension at follow-up (OR 2.7, 95 % CI 0.9 to 7.5; p=0.07). The result persisted after further adjustment for body mass index at follow-up (OR 2.9, 95 % CI 1.0 to 8.3; p=0.05). Diastolic blood pressure was higher for very slow runners at adolescence compared to very fast runners, the age-adjusted mean diastolic blood pressure being 90 mm Hg (95 % CI 86 to 93) vs. 83 mm Hg (95 % CI 80 to 87), age-adjusted p=0.013. High endurance type fitness in adolescence predicts low risk of hypertension and low resting diastolic blood pressure levels in adult men.

Pajoutan, Mojdeh; Cavuoto, Lora A; Mehta, Ranjana K

2017-10-01

This study evaluates whether the existing force-endurance relationship models are predictive of endurance time for overweight and obese individuals, and if not, provide revised models that can be applied for ergonomics practice. Data was collected from 141 participants (49 normal weight, 50 overweight, 42 obese) who each performed isometric endurance tasks of hand grip, shoulder flexion, and trunk extension at four levels of relative workload. Subject-specific fatigue rates and a general model of the force-endurance relationship were determined and compared to two fatigue models from the literature. There was a lack of fit between previous models and the current data for the grip (ICC = 0.8), with a shift toward lower endurance times for the new data. Application of the revised models can facilitate improved workplace design and job evaluation to accommodate the capacities of the current workforce.

Full Text Available Krukenberg tumors mostly occur after 40 years. Metastatic ovarian tumors in young age are very rare and reported to be 2% of all the cases. Thirty percent of all ovarian neoplasms occurring during childhood and adolescence are malignant. A 25-year-old woman, parity- 2, presented with abdominal distension, pain in abdomen and amenorrhea. On examination, 18 weeks lump was palpable, firm to hard in consistency, non-tender and mobile. On ultrasonography bilateral ovarian tumors were reported, without any peritoneal free fluid. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Microscopic examination revealed signet ring cells with glandular differentiation, diffusely invading the ovarian parenchyma. Tumor cells exhibited strong, diffuse immunopositivity for CEA with focal strong immunopositivity for CK7 and CK20 and immunonegativity for SATB2. Diagnosis of Krukenberg tumor was made. Endoscopic biopsy confirmed the diagnosis of adenocarcinoma stomach. This case is reported because of its rarity in younger age group.

1993-06-01

Many daily activities, from basic grooming to employment tasks, require adequate unsupported arm endurance (UAE). We developed an electromechanical device to measure UAE endurance. The purpose of this study was to standardize the instrument for two rates of arm motion, moderate and slow, in 18 normal adult subjects (FEVI = 3.7L +/- .78, FVC = 4.2L +/- .74, FEV1/FVC = 1.1 +/- .08). Exercise endurance limits, and the following metabolic, ventilatory, and sensation responses were determined at rest prior to exercise and at end-exercise limits for both rates of UAE:minute ventilation (Ve), tidal volume (VT), respiratory rate (RR), duty cycle (Ti/Ttot), oxygen uptake (VO2), carbon dioxide production (VCO2), inspiratory flow (VT/Ti), heart rate (HR), and visual analog scale measurements (VAS) of dyspnea (D), respiratory effort (RE), and arm fatigue (AF). Significance increases from baseline rest were shown at the endurance limits for both rates of UAE in: VO2, VCO2, Ve, VT, RR, VT/Ti, HR, VAS-D, VAS-RE, and VAS-AF. There were no changes in Ti/Ttot and SaO2 with UAE. Peak VO2, RR, Ve, VT/Ti, and VAS-D with moderate exercise were significantly greater than slow UAE; and there was a trend increase in peak HR for moderate as opposed to slow rate UAE. Despite these differences, the endurance time between the two rates of UAE were similar. These data provide standards against which UAE in COPD can be evaluated.

Full Text Available The aim of this study was to explore the patriarchal discourses that are still presently registered in the concepts of family. The participant was a woman-mother, victim of violence during her childhood and adult life, whose daughters were victims of incest. The case study was based on semi-structured interviews. Discursive Analysis showed that patriarchal values correspond to the participant's concept of family. Her concept of family revealed to be an idealized nuclear, monogamy, patriarchal and bourgeois model of family, even though this model has not effectively been experienced by her. Since the data was obtained from only one case, new investigations are recommended. We intend to question the hegemonic patriarchal model of family that still endures in our society, whose imperatives have been associated to the dynamics of violent and incestuous families.

Full Text Available Antiphospholipid syndrome is a systemic autoimmune disease with thrombotic tendency. Consensus guidelines for pregnancy with antiphospholipid syndrome recommend low-dose aspirin combined with unfractionated or low-molecular-weight heparin because antiphospholipid syndrome causes habitual abortion. We report a 36-year-old pregnant woman diagnosed with antiphospholipid syndrome receiving anticoagulation treatment. The patient developed left abdominal pain and gross hematuria at week 20 of pregnancy. An initial diagnosis of left ureteral calculus was made. Subsequently abdominal-pelvic computed tomography was required for diagnosis because of the appearance of severe contralateral pain. Computed tomography revealed serious renal hemorrhage, and ureteral stent placement and pain control by patient-controlled analgesia were required. After treatment, continuance of pregnancy was possible and vaginal delivery was performed safely. This is the first case report of serious renal hemorrhage in a pregnant woman with antiphospholipid syndrome receiving anticoagulation treatment and is an instructive case for urological and obstetrical practitioners.

Carmen Aguirre (1931-1971) was a young woman who lived as a self-made man in the 1960s under the brutal, yet populist, right-wing Somoza dictatorship in Nicaragua. Carmen was known as Carmelo or la Caimana (the alligator woman). This article sheds light not only on la Caimana's life, but on how he is remembered today in Nicaragua. It addresses dynamics of Nicaragua's sexual past, present, and future, as well as theoretical questions dealing with identity, sex, and politics.
