Effect of cyclosporine A on bone density in female rheumatoid arthritis patients: results from a multicenter, cross-sectional study.

OBJECTIVE To analyze the influence of cyclosporine A (CYA) on bone using data from a large multicenter, cross-sectional study on bone mineral density (BMD) in rheumatoid arthritis (RA). METHODS We selected 558 female patients with RA and divided them into two groups on the basis of CYA use: those who had never used CYA (n = 467) and CYA users (n = 91; users for < 24 months n = 50; users for > 24 months n = 41). Demographic, disease and treatment-related variables were collected for each patient. BMD was measured at the lumbar spine and proximal femur using dual x-ray absorptiometry. Data was analyzed by means of a univariate and multivariate statistical procedure. Osteoporosis (OP) was defined as BMD < -2.5 T score. RESULTS The frequency of OP among non-CYA users and CYA users was 28.2% and 33.3% (p=NS) for the lumbar spine, and 34.2% and 31.3% (p=NS) for the femoral neck, respectively. The prevalence of fragility fractures was not significantly different between the two groups. Mean values for the T-score at either the lumbar spine or the femoral neck were comparable in the two groups, even after adjustment for age, menopausal status, body mass index (BMI), Health Assessment Questionnaire (HAQ) score and steroid use. The generalized linear model showed that age, BMI and the HAQ score were significant independent predictors of BMD at the lumbar and femoral levels, whereas CYA use was not. Logistic analysis showed that only age, the HAQ score and BMI were significantly associated with the risk of OP. However, the duration of CYA therapy > 24 months was associated with an adjusted decreased lumbar BMD and a significantly decreased femoral neck BMD (p = 0.01). The frequency of femoral neck OP in patients on CYA for > 24 months was significantly higher than in patients on CYA for < 24 months: 46.4% vs. 19.44% (p=0.03), while the prevalence of fragility fractures did not differ significantly: 23.1% vs. 16.6%, respectively (p=NS). Logistic analysis showed that CYA use was an independent predictor of osteoporosis at the femoral site. CONCLUSION Long-term CYA therapy may have negative effects on BMD in female RA patients.
The Quality of Nutrition and Cancer Reviews: A Systematic Assessment

The methodological quality of published reviews of nutrition and cancer (2008–2009) and of the carcinogenicity of acrylamide (1999–2009) was systematically assessed. Each review was examined with respect to four characteristics: whether the purpose of the review was explicitly stated, whether a methods section (detailing the methods used to “weigh” the evidence) was included, whether “weight of evidence” methods were described elsewhere in the paper (e.g., in the discussion), and finally, whether references to recognized “weight of evidence” methods were included. In this study, ninety per cent of a systematically selected sample of recent reviews on nutrition and cancer published in 2008–2009 and 74% of reviews on acrylamide on cancer published in 1999–2009 were found to be methodologically troublesome or frankly unsound. Failure of peer review and editorial oversight are possible explanations, suggesting a broad lack of concern about this issue in the scientific community. If peer reviewers in the nutrition and cancer community do not require “weight of evidence” methods, then these methods may not appear in the published reviews. Similarly, if journal editors (or editorial policies) do not require methods sections in literature reviews, then these sections may not appear. The prerogative of the author(s) seems the most likely determinant of whether a systematic approach is used or not in nutrition and cancer reviews.
Matters of Spirituality at the End of Life in the Pediatric Intensive Care Unit

OBJECTIVE. Our objective with this study was to identify the nature and the role of spirituality from the parents' perspective at the end of life in the PICU and to discern clinical implications. METHODS. A qualitative study based on parental responses to open-ended questions on anonymous, self-administered questionnaires was conducted at 3 PICUs in Boston, Massachusetts. Fifty-six parents whose children had died in PICUs after the withdrawal of life-sustaining therapies participated. RESULTS. Overall, spiritual/religious themes were included in the responses of 73% (41 of 56) of parents to questions about what had been most helpful to them and what advice they would offer to others at the end of life. Four explicitly spiritual/religious themes emerged: prayer, faith, access to and care from clergy, and belief in the transcendent quality of the parent-child relationship that endures beyond death. Parents also identified several implicitly spiritual/religious themes, including insight and wisdom; reliance on values; and virtues such as hope, trust, and love. CONCLUSIONS. Many parents drew on and relied on their spirituality to guide them in end-of-life decision-making, to make meaning of the loss, and to sustain them emotionally. Despite the dominance of technology and medical discourse in the ICU, many parents experienced their child's end of life as a spiritual journey. Staff members, hospital chaplains, and community clergy are encouraged to be explicit in their hospitality to parents' spirituality and religious faith, to foster a culture of acceptance and integration of spiritual perspectives, and to work collaboratively to deliver spiritual care.
Clinical Characteristics and 30-Day Outcomes of Intermittent Hemodialysis for Acute Kidney Injury in an African Intensive Care Unit

Introduction. Acute kidney injury (AKI) is a common occurrence in the intensive care unit (ICU). Studies have looked at outcomes of renal replacement therapy using intermittent haemodialysis (IHD) in ICUs with varying results. Little is known about the outcomes of using IHD in resource-limited settings where continuous renal replacement therapy (CRRT) is limited. We sought to determine outcomes of IHD among critically ill patients admitted to a low-income country ICU. Methods. A retrospective review of patient records was conducted. Patients admitted to the ICU who underwent IHD for AKI were included in the study. Patients' demographic and clinical characteristics, cause of AKI, laboratory parameters, haemodialysis characteristics, and survival were interpreted and analyzed. Primary outcome was mortality. Results. Of 62 patients, 40 had complete records. Median age of patients was 38.5 years. Etiologic diagnoses associated with AKI included sepsis, malaria, and ARDS. Mortality was 52.5%. APACHE II (OR 4.550; 95% CI 1.2–17.5, p = 0.028), mechanical ventilation (OR 13.063; 95% CI 2.3–72, p = 0.003), and need for vasopressors (OR 16.8; 95% CI 3.4–82.6, p = 0.001) had statistically significant association with mortality. Conclusion. IHD may be a feasible alternative for RRT in critically ill haemodynamically stable patients in low resource settings where CRRT may not be available.
Children's and young people's experiences of chronic renal disease: a review of the literature, methodological commentary and an alternative proposal.

AIM The aims of this paper were to review and critique existing research literature on children's and young people's experiences of chronic renal disease and to propose alternative approaches that may be more fruitful in addressing existing research shortcomings. BACKGROUND Chronic renal disease, which results in approximately 1.6-4 new cases per year per million population in the 0-15 years age group, is a serious illness that causes severe and irreversible reduction in kidney function. Despite modern medical advances, its significance and implications for the lives of the children and young people concerned are profound. METHOD Salient literature for this review was obtained using the major health and social science electronic databases such as Medline, CINAHL, Psyclit and Sociofile. Manual searching of relevant books, journals and 'grey literature', combined with the genealogy approach, extended and strengthened the search. CONCLUSIONS Research in this area focuses mainly on two areas, namely psychological adjustment and adaptation to end-stage renal disease. This research is grounded within a framework of empirical psychology that values objectivity, measurement and quantification. This predominantly psychometric approach is critiqued for simplifying the complex experience of end-stage renal disease and for pathologizing children and young people with this disease. We identify a significant gap in the research literature, namely the lack of research that takes into account these children's and young peoples'own perspectives of their experiences. RELEVANCE TO CLINICAL PRACTICE Chronic renal disease has a significant impact on children's and young people's lives. Understanding the experiences of these children is important for the provision of effective healthcare. Conducting child-centred qualitative research in this area would allow us to explore vital questions of meaning, perception and understanding. If health and social care organizations claim to provide 'consumer-focused' services, it behoves us to develop first a clearer understanding of the lives and experiences of children and families who seek our help and to use this knowledge and understanding to plan and provide more grounded and responsive services.
Blocked muscle fat oxidation during exercise in neutral lipid storage disease.

OBJECTIVE To determine whether impaired exercise capacity in neutral lipid storage disease with myopathy is solely caused by muscle weakness or whether a defect in energy metabolism (blocked fat oxidation) may also play a role. DESIGN We studied a 37-year-old woman with neutral lipid storage disease with myopathy, who cycled while lipid oxidation was assessed using U-(13)C palmitate tracer dilution technique. The effect of a glucose infusion during exercise was also studied. SETTING Neuromuscular research unit. RESULTS The exercise-induced increase in fat oxidation was virtually abolished in the patient. Treatment with intravenous glucose infusion improved maximal oxygen uptake from 23 to 27 mL × kg(-1) × min(-1), and maximal workload from 75 to 100 W. CONCLUSIONS These results demonstrate that in addition to fixed weakness, neutral lipid storage disease with myopathy is also characterized by a profound block in fat oxidation, which limits exercise tolerance.
The efficacy of virtual reality assisted versus traditional rehabilitation intervention on individuals with functional ankle instability: a pilot randomized controlled trial

Abstract Purpose: Virtual reality (VR) training, a virtual environment commonly generated by computer systems, may enhance the therapeutic efficacy of functional rehabilitation programmes. The aim of this study was to investigate the efficacy of a VR assisted intervention (VRAI) versus traditional rehabilitation intervention (TRI) on functional ankle instability (FAI). Methods: A single-blind randomized controlled study was conducted with 10 subjects for each group. The VRAI was conducted with the Nintendo Wii Fit Plus, whilst the TRI was conducted with a series of exercises with theraband. The muscle strength change of the two groups and the difference between pre and post interventions for each group were compared. Results: The VRAI group had less improvement in the muscle strength of all ankle motions than did the TRI group (p > .05). The VRAI group had a greater improvement in muscle strength of plantar flexion than other motions, whilst the TRI group had an improvement in muscle strength of all ankle motions (p < .05). Conclusions: The effects of VR training for the condition of FAI were not comparable to conventional training. However, VR training may be added to the conventional training programme as an optional for the condition of FAI. Implications for Rehabilitation Functional ankle instability (FAI) is subjective feelings of ankle instability resulting from proprioceptive and neuromuscular deficits in which individuals may experience “giving way” condition of the ankle. Therapeutic applications of virtual reality (VR) may be comparable to traditional rehabilitation interventions (TRI) in the rehabilitation of individuals with FAI. However, there is no definitive evidence for the issue. Integrating low-cost VR into functional rehabilitation programme can provide insight into an issue of whether it can be replaced with traditional therapeutic approaches. Although, the efficacy of VR application on strengthening muscles is unable to compare to traditional strengthening programmes, it may be considered an optional treatment based on the proprioceptive improvements.
Differential Regulation of Estrogen-Inducible Proteolysis and Transcription by the Estrogen Receptor α N Terminus

ABSTRACT The ubiquitin-proteasome pathway has emerged as an important regulatory mechanism governing the activity of several transcription factors. While estrogen receptor α (ERα) is also subjected to rapid ubiquitin-proteasome degradation, the relationship between proteolysis and transcriptional regulation is incompletely understood. Based on studies primarily focusing on the C-terminal ligand-binding and AF-2 transactivation domains, an assembly of an active transcriptional complex has been proposed to signal ERα proteolysis that is in turn necessary for its transcriptional activity. Here, we investigated the role of other regions of ERα and identified S118 within the N-terminal AF-1 transactivation domain as an additional element for regulating estrogen-induced ubiquitination and degradation of ERα. Significantly, different S118 mutants revealed that degradation and transcriptional activity of ERα are mechanistically separable functions of ERα. We find that proteolysis of ERα correlates with the ability of ERα mutants to recruit specific ubiquitin ligases regardless of the recruitment of other transcription-related factors to endogenous model target genes. Thus, our findings indicate that the AF-1 domain performs a previously unrecognized and important role in controlling ligand-induced receptor degradation which permits the uncoupling of estrogen-regulated ERα proteolysis and transcription.
Laparoscopic Cerclage as a Treatment Option for Cervical Insufficiency

Abstract Background: The traditional surgical treatment for cervical insufficiency is vaginal placement of a cervical cerclage. However, in a small number of cases a vaginal approach is not possible. A transabdominal approach can become an option for these patients. Laparoscopic cervical cerclage is associated with good pregnancy outcomes but comes at the cost of a higher risk of serious surgical complications. The aim of the present study was to evaluate intraoperative and long-term pregnancy outcomes after laparoscopic cervical cerclage, performed either as an interval procedure or during early pregnancy, using a new device with a blunt grasper and a flexible tip. Methods: All women who underwent laparoscopic cervical cerclage for cervical insufficiency in our institution using the Goldfinger® device (Ethicon Endo Surgery, Somerville, NJ, USA) between January 2008 and March 2014 were included in the study. Data were collected from the patientsʼ medical records and included complications during and after the above-described procedure. Results: Eighteen women were included in the study. Of these, six were pregnant at the time of laparoscopic cervical cerclage. Mean duration of surgery was 55 ± 10 minutes. No serious intraoperative or postoperative complications occurred. All patients were discharged at 2.6 ± 0.9 days after surgery. One pregnancy ended in a miscarriage at 12 weeks of gestation. All other pregnancies ended at term (> 37 weeks of gestation) with good perinatal and maternal outcomes. Summary: Performing a laparoscopic cervical cerclage using a blunt grasper device with a flexible tip does not increase intraoperative complications, particularly in early pregnancy. We believe that use of this device, which is characterized by increased maneuverability, could be an important option to avoid intraoperative complications if surgical access is limited due to the anatomical situation. However, because of the small sample size, further studies are needed to confirm our findings.
Paternal uniparental disomy in monozygotic twins discordant for hemihypertrophy

Hemihypertrophy, or hemihyperplasia, is a condition in which there may be asymmetrical overgrowth of the cranium, face, trunk, and/or limbs on one side of the body.1 There may also be asymmetrical visceromegaly on the ipsilateral or contralateral side.2 Hemihypertrophy may occur in isolation, hence the term “isolated hemihypertrophy (IH)”, or as part of a number of overgrowth syndromes in which other characteristic clinical features are present. Such syndromes include neurofibromatosis, Klippel-Trenaunay-Weber syndrome, McCune-Albright syndrome, and Beckwith-Wiedemann syndrome (BWS). 1 The incidence of IH is ∼1/86 000 live births,3 with a male:female ratio of 1:2.1 The aetiology of IH is unknown. A number of different chromosomal anomalies, including diploid-triploid mosaicism and trisomy 18 mosaicism, have been identified, and the causes of IH are likely to be heterogeneous.2 It has been suggested that IH may be one end of the spectrum of phenotypes of BWS, linked to the chromosomal locus 11p15.1 Here we report a case of apparently isolated hemihypertrophy in one of a pair of monozygotic twins, with paternal uniparental disomy in an area of the 11p15 locus associated with BWS. The subjects of the study are a pair of female twins, one of whom (twin 2) has hemihypertrophy. Twin 1 has a normal physical appearance. The twins were born at 36 weeks of gestation by normal vaginal delivery. Twin 1 weighed 2730 g and twin 2 weighed 3205 g. Apgar score at birth was 10 for each girl. Twin 1 fed well and gained weight as expected with no neonatal problems. Twin 2 initially failed to pass meconium and was intolerant of feeds. She was noted to have hemihypertrophy affecting the right leg and arm and an ultrasound scan showed enlargement of the right kidney. She was given a glycerine suppository and passed meconium …
Needle tract seeding after radiofrequency ablation of hepatic tumors.

PURPOSE To determine the incidence and risk factors associated with needle tract seeding after radiofrequency ablation (RFA) of liver tumors. MATERIALS AND METHODS A prospective data base of patients with hepatic tumors treated by RFA from December 1999 until August 2003 was reviewed to identify patients with needle tract seeding. During this period, 200 patients (148 men, 52 women) with 299 lesions underwent 298 treatment sessions. Patients with both primary (153 hepatocellular carcinoma, two cholangiocarcinoma) and a variety of secondary tumors (35 colorectal, 10 other) were treated. RFA was performed percutaneously with computed tomography (CT) and/or ultrasound (US) guidance, or with US guidance at laparoscopy or laparotomy. All procedures were performed with a LeVeen needle electrode. The needle tract was not routinely coagulated or embolized. RESULTS Eight patients out of 200 (4%) were identified with needle tract seeding, based on imaging findings or surgical reintervention. This corresponds to a rate of eight of 298 (2.7%) per treatment session and eight of 299 (2.7%) per lesion. Statistically significant risk factors for neoplastic seeding included treatment of a subcapsular lesion (OR = 11.57, P = .007), multiple treatment sessions (OR = 2.0, P = .037), and multiple electrode placements (OR = 1.4, P = .006). CONCLUSIONS Neoplastic seeding may occur after RFA of liver tumors. The results show that the frequency of this complication is not insignificant, and are at the upper end of rates reported in the literature of 0.5% to 2.8%. Specific risk factors identified in this study include treatment of subcapsular lesions, patients treated in multiple sessions, and lesions requiring more than one electrode placement.
Incidence and clinical predictors of psoriatic arthritis in patients with psoriasis: a population-based study.

OBJECTIVE To determine the incidence and disease-specific predictors of clinically recognized psoriatic arthritis (PsA) in patients with psoriasis. METHODS We identified an incidence cohort of psoriasis subjects age >/=18 years diagnosed between January 1, 1970 and December 31, 1999 in a population-based setting. Psoriasis diagnoses were validated by confirmatory diagnosis in the medical record. Incident and clinically recognized PsA subjects were classified according to the Classification of Psoriatic Arthritis (CASPAR) criteria. Cox proportional hazards models were used to identify predictors of PsA within the psoriasis cohort. RESULTS The psoriasis incidence cohort comprised 1,633 subjects. Of these, 40 were diagnosed with PsA concurrently with psoriasis and were excluded from analysis. The remaining 1,593 psoriasis subjects had a mean age of 43 years and 50% were men. Over 20,936 person-years of followup, 57 subjects were clinically recognized with new-onset PsA, with a cumulative incidence of 1.7% (95% confidence interval [95% CI] 1.0-2.3%), 3.1% (95% CI 2.2-4.1%), and 5.1% (95% CI 3.7-6.6%) at 5, 10, and 20 years following psoriasis incidence, respectively. Psoriasis features associated with higher risk of PsA were scalp lesions (hazard ratio [HR] 3.89, 95% CI 2.18-6.94), nail dystrophy (HR 2.93, 95% CI 1.68-5.12), and intergluteal/perianal lesions (HR 2.35, 95% CI 1.32-4.19). Calendar year was not associated with risk of PsA (P = 0.15), indicating that the likelihood of PsA in psoriasis subjects did not change over time. CONCLUSION In this population-based study, <10% of patients with psoriasis developed clinically recognized PsA during a 30-year period. Psoriasis features associated with a higher likelihood of PsA were nail dystrophy, scalp lesions, and intergluteal/perianal psoriasis.
Is Constipation Associated with Decreased Physical Activity in Normally Active Subjects?

BACKGROUND:The effectiveness of physical activity in the management of constipation remains controversial. We examined the associations among physical activity, constipation, and quality of life (QoL) in a population of employed adults to determine whether the risk of constipation is related to physical activity.METHODS:A total of 1,069 employees (age range 24–77) of the Veterans Affairs (VA) Black Hills Health Care System were mailed validated questionnaires (response rate 72%), inquiring about bowel habits, QoL (SF 36), and physical activity (modified Baecke questionnaire). Constipation was defined using the Rome I criteria.RESULTS:One hundred and forty (19.4%, 95% CI 16.2–22.4) employees reported constipation. The average total physical activity and all subscales of physical activity were not significantly different in subjects with and without constipation (all p≥ 0.2). Subjects with constipation had lower QoL scores than subjects without constipation, and physical activity was positively correlated with physical functioning and health perception.CONCLUSION:Physical activity appears to be unrelated to the risk of constipation in employed adults, but higher physical activity was associated with improved QoL. Recommendations to increase physical activity may not alter symptoms of constipation but may improve overall well-being.
