Validity of using a work habits scale for the daily evaluation of nurse anesthetists' clinical performance while controlling for the leniencies of the rating anesthesiologists

Study objectiveAnesthesiologists can provide psychometrically reliable daily evaluations of certified registered nurse anesthetist (CRNA) work habits for purposes of the mandatory ongoing professional practice evaluation (OPPE). Our goal was to evaluate the validity of assessing CRNA work habits.DesignObservational study.SettingLarge teaching hospital.MeasurementsN = 77 anesthesiologists evaluated work habits of N = 67 CRNAs. The non-technical attribute of work habits was measured on a 6-item scale (e.g., 1 = “Only assumed responsibility when forced to, and failed to follow through consistently” versus 5 = “Consistently identified tasks and completed them efficiently and thoroughly”). One year of scores were used to assess validity. Each daily evaluation could also be accompanied by a written comment. Content analysis of comments was performed using two years of data. Statistical analyses were performed using mixed effects logistic regression, treating each anesthesiologist as a fixed effect to compensate for the leniency of their ratings.Main resultsThe N = 77 anesthesiologists' response rate was 97.3%, obtained at a mean 2.93 days after the request. The internal consistency of the scale was large: Cronbach's alpha 0.952. Controlling the false discovery rate at 5.0%, among the 67 CRNAs, 8 were significantly below average (each P ≤ 0.0048) and 6 were above average (each P ≤ 0.0018). During the 6 months after CRNAs knew that their work habits scores would be used for OPPE, there were significant increases in the scores compared with the preceding 6 months (odds ratio 1.93, P < 0.0001). Greater CRNA's qualitative annual evaluation scores made by the chief CRNA, without knowledge of the work habit scores or comments, were associated with greater odds of the CRNA's leniency-adjusted work habit scores equaling 5.00 (odds ratio 1.53, P = 0.0004). Comments of negative sentiment made by the anesthesiologists were associated with greater odds of the leniency-adjusted work habit scores being < 5.00 (odds ratio 54.5, P < 0.0001). Even though the anesthesiologists were already providing information about work habits using the work habits scale, approximately half the comments of negative sentiment included the theme of work habits (92/153, 60.1%).ConclusionsReporting OPPE metrics are mandatory for the maintenance of clinical privileges of anesthesia practitioners in the USA. Basing such peer review on work habits can be quantitative, psychometrically reliable, and valid.     

La población gitana tiene miedos sobre la donación de órganos propios para trasplante

IntroductionThe refusal rate for donating organs among the Roma people is much higher than that of any other social group.ObjectiveTo analyze the attitude towards the donation of one's own organs among the Roma population living in Spain.MethodsType of study: Spanish national observational sociological study stratified by gender and age. Study population: Roma population aged ≥ 15 years living in Spain. Sample size: 1253 respondents. Assessment instrument: validated questionnaire on attitude towards organ donation for transplantation PCID-DTO Ríos. Field work: random selection based on stratification. Anonymous and self-administered completion. The collaboration of people of Roma ethnicity was required. Statistics: Student's t test, χ², Fisher's exact test and a logistic regression analysis.ResultsThe degree of completion was 18.2% (n = 228). Of those who completed the questionnaire, 42.1% (n = 96) were in favor of donation, 30.3% (n = 69) were undecided and the remaining 27.6% (n = 63) were against it. Of the 1025 (81.8%) who declined to complete the questionnaire, 1004 (98%) indicated that it was for fear of speaking about and filling in a questionnaire that raises the issue of death and organ donation after death. If those who did not complete the questionnaire due to fear of death and donating organs after death are considered not in favor, the results would be as follows: 7.8% (n = 96) in favor of donating their organs compared to 92.2% (n = 1136) not in favor (against or undecided).ConclusionsA majority of the Roma population prefer not speak of death nor organ donation after death. These findings show that current campaigns to promote organ donation are not effective in this population group.     

Épidémiologie de la maladie rénale chronique en République démocratique du Congo : une revue synthétique des études de Kinshasa,la capitale

Chronic kidney disease (CKD) is a worldwide public health problem. Little is known about its burden in Africa. This paper reviews the knowledge of CKD in Kinshasa, summarizing four studies undertaken in the general population and traditional health system of Kinshasa. CKD was defined by either kidney damage (proteinuria ≥ 300 mg/day) or reduced kidney function (eGFR < 60 ml/min/1.73 m²). In the general population, the prevalence of CKD all stage is 12.4 %. Our work shows also the high prevalence of proteinuria among subjects who do not have diabetes or hypertension, the lack of early detection and management of CKD risk factors in the traditional health care system leading to late referral or premature deaths, and the limits of renal replacement treatment. CKD affects young people in the DRC, in contrast to the United States, where CKD is more prevalent in older people. Major determinants of CKD in our studies were hypertension, diabetes, overweight, age, lower socioeconomic status, and Human immunodeficiency virus (HIV) infection. Glomerular nephropathy (mainly focal segmental glomerulosclerosis) remains the leading cause of end stage renal disease. An annual screening of the population for proteinuria and CKD risk factors is feasible and will, it is hoped, provide the basis for building a nationwide prevention strategy.     

Impact of the ankylosing spondylitis on the professional activity

Purpose of the studyAnkylosing spondylitis (AS) is a chronic inflammatory disease affecting axial skeleton, occurring in young and active patients and often condition their professional prospects.ObjectivesTo describe the social and occupational characteristics of patients affected by AS, to estimate the impact of the disease on their professional activity and to determine factors exposing to elevated risk of premature withdrawal from the labor force.MethodsWe had performed a cross-sectional study of 103 patients with AS recruited during 2 years (2005–2007) at the Department of Rheumatology, fulfilling the modified criteria of New York. Demographic, social and professional characteristics were determinated and some disease-specific instruments: BASDAI, BASFI, BASMI, BASG-s, BASRI, as well as an indicator of quality of life: the Short Form Survey-36 (SF-36).ResultsIt is about 88 man and 15 women, the average age is 37.6 years ± 11.7 (18–59 years). Seventy percent of patients live in urban zone and 17% have an educational level superior to 13 years. The disease duration is on average of 11.2 ± 9.6 years. The mean score of BASFI is 45.5 ± 27.5 (7–100), the mean score of BASDAI is 45.9 ± 22.4 (9–100), the mean score of BASG-s is 53.8 ± 21.2, the mean score of BASMI is of 4.4 ± 2.2 (3–10), the mean score of BASRI is 8.4 ± 3.5 (2–16). Among these patients 95 (92%) are eligible to a professional activity (aged between 18 and 65 years and having ended their studies or vocational training). The global unemployment rate is 25.3%, that's attributed to the disease is 20.6%. Some factors are associated with high risk of work withdrawal: female gender (p = 0.0005), low educational level (p = 0.02), living in rural zone (p = 0.028), manual labor (p = 0.038), cold exposing in work place (p = 0.006), high work time a week (p = 0.02) and the absence of colleague help (p = 0.001). For the specific disease indexes, high risk of withdrawal is correlated with high scores of BASFI (p = 0.00002), BASDAI (p = 0.044), BAS-Gs (p = 0.0005) and BASMI (0.0000). Concerning the SF-36, only the item of physical activity is more significantly altered in patient's having stopped their work.ConclusionSeveral factors are identified to be associated to a high risk of premature working withdrawal in patients affected by AS. Prevention of this risk needs an early diagnosis and treatment of the disease, a vocational guidance, work preliminary training and eventually professional redeployment.     

Long-term follow-up of trauma patients before and after implementation of a physician-staffed helicopter: A prospective observational study

IntroductionThe first Danish Helicopter Emergency Medical Service (HEMS) was introduced May 1st 2010. The implementation was associated with lower 30-day mortality in severely injured patients. The aim of this study was to assess the long-term effects of HEMS on labour market affiliation and mortality of trauma patients.MethodsProspective, observational study with a maximum follow-up time of 4.5 years. Trauma patients from a 5-month period prior to the implementation of HEMS (pre-HEMS) were compared with patients from the first 12 months after implementation (post-HEMS). All analyses were adjusted for sex, age and Injury Severity Score.ResultsOf the total 1994 patients, 1790 were eligible for mortality analyses and 1172 (n = 297 pre-HEMS and n = 875 post-HEMS) for labour market analyses. Incidence rates of involuntary early retirement or death were 2.40 per 100 person-years pre-HEMS and 2.00 post-HEMS; corresponding to a hazard ratio (HR) of 0.72 (95% confidence interval (CI) 0.44–1.17; p = 0.18). The HR of involuntary early retirement was 0.79 (95% CI 0.44–1.43; p = 0.43). The prevalence of reduced work ability after three years were 21.4% vs. 17.7%, odds ratio (OR) = 0.78 (CI 0.53–1.14; p = 0.20). The proportions of patients on social transfer payments at least half the time during the three-year period were 30.5% vs. 23.4%, OR = 0.68 (CI 0.49–0.96; p = 0.03). HR for mortality was 0.92 (CI 0.62–1.35; p = 0.66).ConclusionsThe implementation of HEMS was associated with a significant reduction in time on social transfer payments. No significant differences were found in involuntary early retirement rate, long-term mortality, or work ability.     

Fracture-related mortality in southern Sweden: A multiple cause of death analysis, 1998–2014

PurposeTo assess fracture-related mortality among adults (aged ≥20 years) in southern Sweden using multiple causes of death approach.MethodsAll death certificates (n = 201 488) in adults recorded in the region of Skåne from 1998 to 2014 were examined. We identified fracture-related deaths and computed mortality rates by sex, age group, and fracture site. Temporal trends were evaluated using joinpoint regression and associated causes were identified by age- and sex-adjusted observed/expected ratios.ResultsFractures were mentioned on 6 226 (3.1%) death certificates, with majority of these occurred among women (60%) and those aged ≥ 80 years (77%). While hip was the most common site overall (61% of all fracture-related deaths), skull was the most common site in people <60 years (60% of all fracture-related deaths). Proportion of death certificates mentioning fracture was stable in women but increased by 0.4% (95% CI: 0.1 to 0.6) in men between 1998–2002 and 2010–2014. The mean age at death was higher in death certificates mentioning fracture than those without and this gap widened over time. The mean age-standardized fracture-related mortality rate was 18.8 (14.0) per 100 000 person-year in men (women) and declined by 1.5% (1.3%) per year during 1998–2014. Injuries (84.6%) and cardiovascular disorders (64.6%) were the most common comorbidities on death certificates mentioning fracture.ConclusionsFracture is a contributing cause of death in more than 3% of all deaths in southern Sweden with hip in lead among older and skull fracture among younger people. There was a slight increase in proportion of deaths associated with fracture in men but not women during the study period.     

Stigma and optimism in adolescents and young adults with cystic fibrosis

BackgroundDespite increased life expectancy among patients with cystic fibrosis (CF), few studies have examined coping among adolescents and young adults with CF. Previous research suggests that stigma associated with chronic disease is related to worse physical and psychological health, but optimism may be protective. This study examined stigma and optimism among patients with CF.MethodsSeventy-two patients with CF (ages 14 to 25) completed a self-report questionnaire assessing stigma, distress, CF-specific quality of life (QoL), and optimism. Objective health data were recorded from patient medical records.ResultsGreater stigma was associated with lower pulmonary function, QoL, and optimism. Stigma was positively correlated with distress. Optimism moderated the relationship between stigma and anxiety (p < 0.001), and between stigma and emotional functioning (p < 0.01).ConclusionsStigma is related to worse lung function and psychological health in patients with CF, but higher levels of optimism may act as a protective factor.     

The effects of carrying extra weight on ankle stability in adolescent basketball players

PurposeThe purpose of this study was to investigate the effects of weight on ankle stability in adolescent basketball players.Methods20 non-injured subjects (age = 11.05 ± 1.5 years) were included in this study. Each subject performed a 15 min warm-up by running or riding a stationary bike. The Star Excursion Balance Test (SEBT), single-leg balance test (performed with eyes open and eyes closed) and vertical jump test were performed with dominant lower extremity. 1 week later, same tests were performed with a schoolbag. The schoolbag contained weight bars as 20% of the players own body weight.ResultsOnly posteromedial component of SEBT had significant difference between non-weight measurement and weighted measurement (p = 0.004). Single-leg stance test performed with eyes open (p = 0.006) and closed (p = 0.001) had significant difference between non-weight measurement and weighted measurement. Also the vertical jump test had significant difference between non-weight measurement and weighted measurement (p = 0.001).ConclusionsThese findings indicate that 20% weight of their own body weight does not affect dynamic ankle stability and postural limitations, which are magnified by advancing weight. We are confident in our conclusions because of the three-way interaction noted with posterior/medial with weight in SEBT. Furthermore, Star Excursion Balance test is more effective both weight and non-weight in measuring functional stability of the ankle.     

Quels enjeux pour l’inclusion des étudiants à besoins éducatifs particuliers dans l’enseignement supérieur français ?

In spite of the French public policies implemented to meet the needs of students with disability and the promulgation of laws promoting inclusion in higher education, many barriers leading to social exclusion remain. The present paper analyzes the impact of health issues on young people educational path using com semi-structured interviews with high school and university students affected by serious and chronic diseases (n = 19) from a sociological survey. The objective was to identify the needs and aspirations of these young people with disability to propose a suitable response to those needs, while also taking into account existing resources using a co-constructive approach. The analysis highlights the disconnect between the different domains of social interaction in which disabled students are included. Parental support and the transition between upper secondary and higher education are hindered by a lack of institutional cohesion. We investigate how stakeholders in the three institutional domains concerned with the disabled students (educational, medical and family) interact with each other using a systemic and polycentric approach. Our study shows that that a mediator is required to help solve the problems encountered by students with serious and chronic diseases as one possible approach to address their needs.     

Consequences of non-fatal electrical injury: Findings of community-based national survey in Bangladesh

This study was designed to document the consequences of electrical injury in Bangladesh. A community-based cross-sectional survey was conducted from January to December 2003. Nationally representative data were collected from 171,366 rural and urban households, comprising a total of 819,429 population. Face-to-face interview was chosen as a data collection method.The overall rate of electrical injury was 73.7 per 100,000 population-year. The rate of permanent disability due to electrical injury in Bangladesh was 0.366 per 100,000 population-year. Among the total 604 non-fatal electrical injuries in the survey, 282 (46.7%) had suffered from temporary disabilities for different durations. A total of 172 students were injured from electrical injury and among them 139 (80.8%) missed school for different durations due to their illness. Mean duration of absence from school was 9.72 days (SD ± 10.98), ranging from 1 to 45 days. Among the working people average duration of work loss was 10.56 days (SD ± 14.98), ranging from 1 to 90 days. About 39% of the total patients with electrical injury were contributors to their family income. For each family the expenditure for each seriously injured patient due to electrical injury was USD 271.Electrical Injury is a major cause of morbidity in Bangladesh. It is responsible for significant loss of school days and work days and creating serious health and economic hardship for the inflicted families. A nationwide prevention program needs to be developed to address this problem.     

Description des caractéristiques,des projets de soins et du devenir des patients de plus 75 ans présentant une insuffisance rénale sévère (DFGe ≤ 20 mL/min/1,73 m2) : phase pilote du projet PSPA

In France, the incidence of dialysis patients is increasing in people over 75 years and represents 40% of incident patients. In these elderly patients with many comorbidities, the benefit of dialysis in terms of survival and quality of life remains controversial. Using data from REIN, determinants of early mortality were identified and a prognostic score was provided. This approach must now be adapted to elderly with end stage renal failure (ESRF) not on dialysis for which we have little data on their clinical characteristics, therapeutic projects and outcome. We report the results of a pilot study and the prospective study protocol that resulted. In four French nephrology department, 76 patients were studied with a mean age of 83 ± 5 years, with a MDRD estimated GFR (abbreviated MDRD) of 16 ± 4 mL/min/1.73 m². These patients were different from the population on dialysis recorded in REIN. This pilot study has shown the feasibility of a prospective study on a larger scale, which aims to build a valuable tool for decision making in elderly patients with ESRF not yet on dialysis.     

Efficacy of a functional restoration program for chronic low back pain: Prospective 1-year study

ObjectiveTo evaluate the efficacy of a functional restoration program for patients with chronic low back pain, using overall disability and work ability as the primary evaluation criteria.Patients and methodsWe prospectively studied patients aged 18 years or older who had been on sick leave because of nonspecific low back pain for at least 3 months and whose job position was still open. The program was delivered on a day-hospital basis 5 days a week for 5 weeks. Patients were followed up for 1 year.ResultsWe included 39 patients, 11 females and 28 males with a mean (± SD) age of 43 ± 8 years and a mean sick-leave duration of 10 ± 7 months. After 1 year, 26 (67%) patients reported improvements and 25 (64%) had returned to work. Compared to the year before the program, the number of sick leave days was decreased by 51% (120 ± 140 vs. 244 ± 114, P < 0.05). The work-and-leisure-activities subscore of the validated French version of the Dallas Pain Questionnaire (DRAD) was significantly improved (57 ± 24 vs. 70 ± 17 at baseline, P < 0.05). The patients still on sick leave after 1 year were older and had greater alterations in baseline DRAD subscores for anxiety/depression and daily activities, compared to the patients who had returned to work.ConclusionsOur functional restoration program was effective and allowed two-thirds of patients to resume work. Factors associated with failure to resume work were well-known correlates of chronicity. Our results support the use of functional restoration programs in patients with incapacitating low back pain. They suggest that functional restoration may deserve to be started earlier, after only 3 months with chronic pain, in patients who are unable to work.     

El personal no sanitario de hospitales españoles y latinoamericanos ante la donación de vivo renal relacionada

IntroductionAncillary hospital personnel represent an important body of opinion because as they work in a hospital their opinion has more credibility for the general public as a result of their activity in hospitals. However, in most cases they do not have any health care training which means that their attitude could be based on a lack of knowledge or unfounded fears.ObjectiveTo analyze the attitude toward living kidney donation (LKD) among ancillary personnel in Spanish and Latin-American hospitals and to analyze the variables that might influence such attitude.Patients and methodfrom «International Collaborative Donor Project» a random sample was taken among ancillary personnel in Spain, Mexico and Cuba hospitals. Attitude towards LKD was evaluated using a validated, anonymously filled and self-administered survey.Results951 professionals were surveyed (Spain: 277, Mexico: 632, Cuba: 42). 89% (n = 850) are in favor of related kidney donation, lowering to 31% (n = 289) in non-related donation. Of the rest, 8% (n = 78) are not in favor and the 3% (n = 23) are unsure. By country, Cubans (98%) and Mexicans (91%) are more in favour than Spanish (84%) (P = .001). The following variables are related to favourable attitude towards LKD: female sex (P = .017), university degree (P = .010), work in health services (P = .035), labour stability (P = .016), personal experience in donation and transplantation (P = .001), positive attitude toward cadaveric donation (P < .001), belief that he or she might need a transplant in the future (P < .001), positive attitude towards living liver donation (P < .001), a willingness to receive a donated living liver if needed (P < .001), having discussed the subject of organ donation and transplantation within the family (P < .001), partner's positive attitude towards the subject (P < .001), participation in voluntary type pro-social activities (P = .002) and not being concerned about possible mutilation after donation (P < .001)ConclusionsThe attitude toward living related kidney donation is favourable among ancillary personnel in Spanish and Latin-Americans hospitals. Because living donation is a better source of organs than cadaveric ones, this favourable predisposition can be used as promoting agent of living donation in order to develop it in Spanish-speaking countries.     

The pitfall of treating low bone turnover: Effects on cortical porosity

Although it is recognized that cortical bone contributes significantly to the mechanical strength of the skeleton, little is known about this compartment from bone biopsy studies, particularly in CKD patients. In addition, there is no prospective data on the effects of CKD-MBD therapy on cortical porosity (Ct.Po). This is a post hoc analysis on data from a randomized controlled trial on the effects of different phosphate binders on bone remodelling. Therapy was adjusted according to the first biopsy, and included sevelamer or calcium acetate, calcitriol and changes in calcium dialysate concentration. We measured Ct.Po at baseline and one year after. Fifty-two patients (46 ± 13 years old, 67% women and 60% white) were enrolled. Ct.Po was already high at baseline in 85% of patients [30% (17, 46)] and correlated with PTH (p = 0.001). Low bone turnover was seen in 28 patients (54.9%). After one-year treatment, PTH increased in patients with low turnover, as intended. However, increased Ct.Po was seen in 49 patients (94%). This increase correlated with the delta of phosphate (p = 0.015) and the delta of PTH (p = 0.03); it was also higher among non-white patients than in white patients (p = 0.039). The risk of increase in Ct.Po was 4.5 higher among non-white patients. Adjusted multiple regression analysis showed that the delta of Ct.Po was dependent on delta PTH and race (r² = 0.193). We concluded that in an attempt to increase bone turnover, the increase in PTH levels might be associated with higher cortical porosity, particularly in non-white patients. Whether this finding leads to a high risk of fracture deserves further investigation.     

The association between physical activity in different domains of life and risk of osteoporotic fractures

A large body of epidemiological evidence suggests an inverse relationship between physical activity and risk of fractures. However, it is unclear how this association varies according to the domain of life in which the activity is undertaken. In this analysis of the European Prospective Investigation of Cancer-Norfolk study, we assessed total and domain-specific physical activity using a validated questionnaire (EPAQ2) in 14,903 participants (6514 men, mean age 62 year) who also underwent quantitative ultrasound of the heel. After a median follow-up of 7.5 years, there were 504 fractures of which 164 were hip fractures. In multivariable linear regression analysis, broadband ultrasound attenuation (BUA) was positively associated with total and leisure-time activities while showing no association with transportation and work activities. Home activities were associated with a lower BUA among younger participants. In multivariable Cox proportional-hazards models, moderate activities at home and in leisure time were associated with lower hip fracture risk among women (hazard ratios [HR] 0.51 and 0.55, p value 0.02 and 0.03, respectively). Among men, leisure-time activities were associated with lower risk of hip fracture (HR = 0.58; p for trend < 0.001) whereas activities at home were associated with higher risk of any fracture (HR = 1.25; p for trend = 0.008). Walking for leisure or transport was associated with lower risk of fracture in both men and women. Multivariable fractional polynomial modelling showed a U-shaped association between home activities and fracture risk especially among women. This study suggests that different domains of physical activity may relate differently to fracture risk and these relationships may vary by sex.     

There is a difference in functional ankle stability between different types of footwear in male athletes: A cross-sectional study

ContextLateral ankle sprains (LAS) are among the most common injuries in sports, with a poor long – term prognosis due to high chronicity and recurrence rates. Chronic ankle instability (CAI) results up to 40% of people that endured a first – time LAS.ObjectiveThe aim of this study was to compare ankle stability between groups characterised by the use of different types of footwear during their sport activities.DesignCross-sectional study.SettingFirm training surface, local sport clubs.ParticipantsFifty - one male subjects were recruited, distributed in four groups based on the type of footwear they use during their sport activities.Main outcome measuresAll subjects performed four clinical ankle stability tests, and completed the Dutch version of the Cumberland Ankle Instability Tool (CAIT) and Profile of Mood States (POMS). All clinical ankle stability tests were performed barefoot.ResultsSubjects performing their sport activities barefoot scored better than subjects performing their sport with shoes at the multiple hop test (p = .002 to .047) and executed the figure–of–8 hop test significantly faster than subjects with submalleolar ankle support (AS) (p = .019). Subjects with submalleolar AS and studs showed significantly better results than subjects with supramalleolar AS on the CAIT– score (p = .024, p = .030) and the side– hop test (p = .050, p = .045). They also scored significantly better than subjects with submalleolar AS for the side – hop test (p = .032), foot – lift test (p = .019) and figure–of 8 hop test (p = .011).ConclusionBarefoot sports performing subjects appear to have better ankle stability compared to subjects performing their sports with shoe support. Subjects performing sports with high AS appear to have worst ankle stability.Level of evidence: Level III, Cross–sectional study.     

Effects of soy isoflavone supplements on bone turnover markers in menopausal women: Systematic review and meta-analysis of randomized controlled trials

IntroductionEffects of soy isoflavone supplements on bone turnover markers remain unclear. This up-to-date systematic review and meta-analysis of randomized controlled trials (RCTs) was performed primarily to more completely and precisely clarify the effects on urinary deoxypyridinoline (DPD) and serum bone alkaline phosphatase (BAP) and secondarily to evaluate the effects on other bone turnover markers, compared with placebo in menopausal women.MethodsPubMed, CENTRAL, ICHUSHI, and CNKI were searched in June 2009 for relevant studies of RCTs. Data on study design, participants, interventions, and outcomes were extracted and methodological quality of each included trial was assessed.ResultsFrom 3740 identified relevant articles, 10 (887 participants), 10 (1210 participants), and 8 (380 participants) RCTs were selected for meta-analysis of effects on DPD, BAP, and serum osteocalcin (OC), respectively, using Review Manager 5.0.22. Daily ingestion of an average 56 mg soy isoflavones (aglycone equivalents) for 10 weeks to 12 months significantly decreased DPD by 14.1% (95% CI: ? 26.8% to ? 1.5%; P = 0.03) compared to baseline (heterogeneity: P < 0.00001; I² = 93%; random effects model). The overall effect of soy isoflavones on DPD compared with placebo was a significant decrease of ? 18.0% (95% CI: ? 28.4% to ? 7.7%, P = 0.0007; heterogeneity: P = 0.0001; I² = 73%; random effects model). Subgroup analyses and meta-regressions revealed that isoflavone dose and intervention duration did not significantly relate to the variable effects on DPD. Daily supplementation of about 84 mg and 73 mg of soy isoflavones for up to 12 months insignificantly increased BAP by 8.0% (95% CI: ? 4.2% to 20.2%, P = 0.20; heterogeneity: P < 0.00001; I² = 98%) and OC by 10.3% (95% CI: ? 3.1% to 23.7%, P = 0.13; heterogeneity: P = 0.002; I² = 69%) compared with placebo (random effects model), respectively.ConclusionsSoy isoflavone supplements moderately decreased the bone resorption marker DPD, but did not affect bone formation markers BAP and OC in menopausal women. The effects varied between studies, and further studies are needed to address factors relating to the observed effects of soy isoflavones on DPD and to verify effects on other bone turnover markers.     

Rheumatoid arthritis risk in periodontitis patients: A systematic review and meta-analysis

ObjectiveMany clinical studies have been carried out to investigate the relationship between periodontitis and rheumatoid arthritis (RA). Owing to limited evidence and inconsistent findings among these studies, it is unclear whether periodontitis would increase the risk for RA. This meta-analysis was performed to evaluate whether periodontitis represents a risk factor for RA.MethodsPubMed, Cochrane Library, Embase, Web of Science, and Wanfang were searched for eligible studies that compared periodontitis patients with controls. A pooled odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the association between periodontitis and RA.ResultsThirteen studies including a total of 706611 periodontitis patients and 349983 control subjects were included. The pooled OR of RA risk between periodontitis and controls was (OR: 1.69; 95% CI: 1.31–2.17; P < 0.0001), indicating that the patients in periodontitis group had a 69% greater risk for RA than people in control group. When stratified by disease type, the pooled results showed periodontitis represents a risk factor for incident RA (OR = 1.70, 95%CI: 0.75–3.85, P < 0.001) and mixed RA (OR = 1.61, 95%CI: 1.26–2.06; P < 0.001). When stratified by disease duration, the pooled results showed periodontitis represents a risk factor for RA disease duration > 5 years (OR = 2.88, 95%CI: 0.66–12.62, P = 0.018), disease duration < 5 years (OR = 2.59, 95%CI: 0.83–8.11, P < 0.001), mixed disease duration (OR = 1.53; 95%CI: 1.05–2.22, P < 0.001).ConclusionOur meta-analysis revealed an increased risk of RA in patients with periodontitis compared to healthy controls. Moreover, when stratified by disease type, there was a higher risk between incident RA and periodontitis. When stratified by disease duration, the patients with periodontitis might be more closely associated with the RA patients with disease duration >5 years.     

Genetic polymorphisms of UGT1A8, UGT1A9 and HNF-1α and gastrointestinal symptoms in renal transplant recipients taking mycophenolic acid

Mycophenolic acid (MPA), a widely used immunosuppressant, has a complex metabolism that involves a number of enzymes. Some of its metabolites are thought to be the cause of gastrointestinal (GI) side effects. In this study, we investigated whether polymorphisms of UDP-glucuronosyltransferases (UGT1) A8, 1A9, and hepatocyte nuclear factor (HNF1α) genes or pharmacokinetic parameters of mycophenolic acid (MPA) were associated with the severity of GI symptoms in patients receiving MPA therapy.A total of 109 kidney transplant patients taking mycophenolic acid (MPA) derivatives were genotyped for UGT1A8, 1A9 and HNF1α genes. Among these, a total of 15 patients were participants in the pharmacokinetic study. Severity of GI symptoms was assessed using a validated Gastrointestinal Symptom Rating Scale (GSRS). The overall and subscale GSRS scores were measured at 1 week (baseline), 2 weeks, 3 months and 6 months post-transplantation. In the case of the pharmacokinetic study, EC-MPS was administered and a total of nine blood samples were obtained at − 1, 0, 0.5, 1, 2, 4, 6, 8, and 12 h.Genotypes of UGT1A8 were significantly associated with the overall GSRS scores at week 1 (p = 0.02) and week 2 (p = 0.036). Subscales were only statistically significant for constipation at week 1 (p = 0.002) and indigestion at week 2 (p = 0.02), while UGT1A9 was only significant for the constipation at week 1 (p = 0.04). HNF1α genotypes were significantly different at week 1 in the overall GSRS (p = 0.004), and for abdominal pain (p = 0.04), acid reflux (p = 0.036) and constipation subscales (p = 0.04). In addition, abdominal pain was statistically significantly different at 3 months and 6 months after transplantation (p = 0.03 and 0.02, respectively). In the case of the pharmacokinetic study, we have found some correlations between MPA_C0 and constipation (p = 0.02) where MPA_AUC was correlated with acid reflux (p = 0.02) and constipation (p = 0.012), MPAG_CL/F was correlated to acid reflux, indigestion, constipation and the sum of the GSRS scores (p = 0.037, p = 0.032, p = 0.033 and p = 0.04, respectively). Multinomial regression analysis for MPAG_CL/F showed a statistical significance for the subscale indigestion and the sum of the GSRS (p = 0.033 and p = 0.037, respectively).Our data suggests that among patients receiving MPA the UGT1A9 alleles might play a role in determining the severity of early GI side effects, while the HNF1α allele appears to be associated with a later effect as well as early side effects. Our data also showed that some kinetic parameters might predict MPA side effects.
