FRAX® based intervention thresholds for management of osteoporosis in Singaporean women

Summary

Potential FRAX®-based major osteoporotic fracture (MOF) and hip fracture (HF) intervention thresholds (ITs) for postmenopausal Singaporean women were explored. Age-dependent ethnic-specific and weighted mean ITs progressively increased with increasing age. Fixed ITs were derived via discriminatory value analysis. MOF and HF ITs with highest the Youden index were chosen as optimal.

Introduction

We aimed to explore FRAX®-based intervention thresholds (ITs) to potentially guide osteoporosis treatment in Singapore, a multi-ethnic nation.

Method

One thousand and one Singaporean postmenopausal community-dwelling women belonging to Chinese, Malay and Indian ethnicities underwent clinical risk factor (CRF) and BMD assessment. FRAX® major osteoporotic fracture (MOF) and hip fracture (HF) probabilities were calculated using ethnic-specific models. We employed the translational logic adopted by NOGG (UK), whereby osteoporosis treatment is recommended to any postmenopausal woman whose fracture probability based on other CRFs is similar to or exceeds that of an age-matched woman with a fracture. Using the same logic, ethnic-specific and mean weighted age-dependent ITs were computed. Employing these age-dependent ITs as a reference, the performance of fixed (age-independent) ITs were examined using ROC curves and discriminatory analysis, with the highest Youden index (YI) (sensitivity?+?specificity???1) used to identify the optimal MOF and HF ITs.

Results

The mean age was 58.9 (6.9) years. Seven hundred and eighty-nine (79%) women were Chinese, 136 (13.5%) Indian and 76 (7.5%) Malay. Age-dependent MOF ITs ranged from 3.1 to 33%, 2.5 to 17% and 2.5 to 16% whilst HF ITs ranged from 0.7 to 17%, 0.4 to 6% and 0.4 to 6.3% in Chinese, Malay and Indian women, respectively, between the ages of 50 and 90 years. The weighted age-dependent MOF and HF ITs ranged from 2.9% and 0.6%, respectively, at the age of 50, to 28% and 14% at 90 years of age. Fixed MOF/HF ITs of 5.5%/1%, 2.5%/1% and 2.5%/0.25% were identified as the most optimal by the highest YI in Chinese, Malay and Indian women, respectively. Fixed MOFP and HF ITs of 4% and 1%, respectively, were found to be most optimal on the weighted means analysis.

Conclusion

The ITs for osteoporosis treatment in Singapore show marked variations across ethnicities. Weighted mean thresholds may overcome the dilemma of intervening at different thresholds for different ethnicities. Choosing fixed ITs may have to involve trade-offs between sensitivity and specificity. FRAX®-based age-dependent or the fixed intervention thresholds suggested as an alternative to be considered for use in Singapore though further studies on the societal and health economic impacts of choosing these thresholds in Singapore are needed.

     

Prevalence and predictors of overactive bladder in nonpregnant nulliparous women below 65 years of age

Introduction and hypothesis

The aetiology of the overactive bladder (OAB) symptom complex is still poorly understood. In order to obtain further insight, the prevalence and predictors of the symptoms included in OAB, that is urgency, urgency incontinence (UUI), frequency and nocturia, were investigated in a sample of nonpregnant nulliparous women.

Methods

A national, postal and web-based survey of OAB symptoms was conducted in women aged 25–64 years (n = 9,197). Crude prevalence and prevalence adjusted according to body mass index (BMI) were calculated from a logistic regression model to evaluate the prevalence of OAB.

Results

The response rate was 52%. The prevalence of urgency, bothersome urgency, UUI, and nocturia, but not daytime frequency, increased consistently with advancing age and increasing BMI. Urgency was associated with BMI, age ≥45 years, nocturia, and daytime frequency of eight or more micturitions. Daytime urinary micturition frequency was not affected by age either in women with OAB or in women without OAB. Bothersome OAB affected almost half of the woman in the oldest age group and was strongly associated with nocturia of two or more micturitions and OAB with UUI.

Conclusions

There were contrasting changes in the prevalence of the different symptoms included in OAB. With increasing age and BMI, the prevalence of nocturia, urgency and UUI increased, while daytime frequency remained stable. These findings are of importance as the primary endpoint for the evaluation of drug therapies for OAB has often been daytime urinary frequency.

     

Natural history of pessary use in women aged 65 – 74 versus 75 years and older with pelvic organ prolapse: a 12-year study

Introduction and hypothesis

The feasibility of use and long-term outcomes of vaginal pessaries for the management of pelvic organ prolapse (POP) in older women remains unknown. Our aim was to determine successful fit rates and outcomes among older women seeking care for POP.

Methods

This was a retrospective cohort study of 304 consecutive women aged 65 years and older with symptomatic POP undergoing a pessary trial at the outpatient urogynecology clinic in Québec, Canada. Women successfully fitted with a pessary were followed, and survival curves were used to ascertain the median time to pessary discontinuation for women aged 65 to 74 years in comparison with women aged 75 years and older. Long-term use was defined as longer than 1 year. Predictors of a successful fitting and long-term discontinuation were ascertained using logistic and Cox regression analyses.

Results

Half of the women attempting a pessary trial were aged 75 years and older, and 63 % were fitted successfully regardless of age. Women with a history of hysterectomy or reconstructive pelvic surgery, or those with posterior vaginal wall prolapse were more likely to fail initial insertion. For women aged 65 to 74 years and women aged 75 years and older, the cumulative probabilities of continued pessary use were 87.5 % and 80.8 % at 1 year, 80.6 % and 70.9 % at 2 years, and 62.1 % versus 37.8 % at 5 years. Erosions occurred in 19.3 % of long-term users, with women aged 75 years and older more likely to experience vaginal erosions (HR 3.2, 95 % CI 1.6 – 6.3) and discontinue pessary use.

Conclusion

Pessary use is a feasible and acceptable treatment option for the long-term management of symptomatic prolapse in over 60 % of all women aged 65 years and older.

     

Hip arthroplasty with the thrust plate prosthesis in patients of 65 years of age or older: 67 patients followed 2–7 years

Introduction Thrust plate prosthesis (TPP) is a relatively new concept in total hip arthroplasty and advocated to be used in young patients. We retrospectively evaluated the results of 67 patients (71 hips) who were older than 65 years of age and underwent hip arthroplasty using the TPP. Patients and methods There were 50 female and 17 male patients with a mean age 71 (range 65–89) years. All patients received accelerated rehabilitation program either with full weight bearing in the second postoperative day or at 6 weeks. All patients were followed-up for at least 2 years (range 28–87 months). Results The average Harris hip score improved from 43 (range 8–72) to 93 (range 64–100) at the latest follow-up (p < 0.001). The overall revision rate was 8.4%. However, when the patients with definitive history of trauma were excluded the rate for loosening and technical errors decreased to 4.2%. There was no significant difference between the Harris hip score of patients with full weight bearing in the second postoperative day or 6 weeks (p = 0.57). Conclusion We conclude that the TPP could be indicated for older patients without age limit and that an accelerated rehabilitation program with early weight bearing can be applied to these patients.     

Gender-specific hip fracture risk in community-dwelling and institutionalized seniors age 65 years and older

Summary

In this study of acute hip fracture patients, we show that hip fracture rates differ by gender between community-dwelling seniors and seniors residing in nursing homes. While women have a significantly higher rate of hip fracture among the community-dwelling seniors, men have a significantly higher rate among nursing home residents.

Introduction

Differences in gender-specific hip fracture risk between community-dwelling and institutionalized seniors have not been well established, and seasonality of hip fracture risk has been controversial.

Methods

We analyzed detailed data from 1,084 hip fracture patients age 65 years and older admitted to one large hospital center in Zurich, Switzerland. In a sensitivity analysis, we extend to de-personalized data from 1,265 hip fracture patients from the other two large hospital centers in Zurich within the same time frame (total n?=?2,349). The denominators were person-times accumulated by the Zurich population in the corresponding age/gender/type of dwelling stratum in each calendar season for the period of the study.

Results

In the primary analysis of 1,084 hip fracture patients (mean age 85.1 years; 78 % women): Among community-dwelling seniors, the risk of hip fracture was twofold higher among women compared with men (RR?=?2.16; 95 % CI, 1.74–2.69) independent of age, season, number of comorbidities, and cognitive function; among institutionalized seniors, the risk of hip fracture was 26 % lower among women compared with men (RR?=?0.77; 95 % CI: 0.63–0.95) adjusting for the same confounders. In the sensitivity analysis of 2,349 hip fracture patients (mean age 85.0 years, 76 % women), this pattern remained largely unchanged. There is no seasonal swing in hip fracture incidence.

Conclusion

We confirm for seniors living in the community that women have a higher risk of hip fracture than men. However, among institutionalized seniors, men are at higher risk for hip fracture.     

Prostatic biopsies in selected men aged 75 years and older guide key clinical management decisions

Purpose

Increasing life expectancy and PSA testing has increased the number of men over the age of seventy-five presenting for investigation of potential prostate malignancies. Prostatic biopsies provide diagnostic information; however, they are invasive and may not alter management decisions. Therefore, this study aimed to investigate whether prostate biopsies in this age group were justified.

Materials and methods

All men aged 75 years and older who underwent prostatic biopsies between January 2010 and November 2011 at Bedford Hospital were identified and the indication for the biopsies, histopathological results and subsequent management plan investigated.

Results

One hundred and thirty-eight (138) prostatic biopsies were undertaken and malignancies identified in 60/138 (43 %) cases. Prebiopsy PSA and examination findings had a poor positive predictive value of 54 %. Fifty-five out of sixty (92 %) cancers were classified as high or medium risk disease with 30/60 (50 %) patients commencing radiotherapy treatment with curative intent.

Conclusion

In selected patients aged 75 years or over, prostatic biopsies provide important diagnostic information which directly impacts on clinical decisions, supporting their use in this age group.     

Temporal trends in incidence,evaluation and management of neuroendocrine neoplasms of the appendix: 14 years’ experience

BackgroundInformation regarding temporal trends in appendiceal neuroendocrine neoplasms (ANEN) is limited. This retrospective study evaluated temporal trends in ANEN incidence and management over a 14-year period.MethodsAppendectomy pathology reports from a single tertiary center were reviewed.ResultsDuring 2005–2018, 8327 appendectomies were performed and 57 ANENs were diagnosed (average age 31.7 ± 17 years; 70.2% women; 17.5% Arab ethnicity; and 22.8% < 18 years of age). The cohort was divided according to year of diagnosis (Period A 2005–2011; Period B 2012–2018). No differences were found in ANEN incidence (0.75% and 0.62%, respectively, p = 0.104), epidemiologic or pathologic characteristics between periods. In period B, pathology reports were more comprehensive and use of specific imaging and biochemical studies was more prevalent. Hemicolectomy rates and results were similar (8 in Period A, 7 in Period B, p = 0.925). All patients remained alive for the duration of follow-up.ConclusionsNo temporal changes in epidemiological, clinical or pathological features of ANENs were noted. Although clinico-pathological evaluation was more detailed after 2011, there was no change in rates of hemicolectomy or disease prognosis.     

Prevalence of osteoporosis and fractures among women prescribed osteoporosis medication in five European countries: the POSSIBLE EU® study

Summary  

European observational 1-year study assessed osteoporosis and fracture patterns in 3,402 postmenopausal women prescribed osteoporosis medication. Almost 40% of patients had a previous fracture, while 25% had neither fracture nor dual energy X-ray absorptiometry (DXA) diagnosis and were prescribed medication, probably due to other risk factors.     

Excellent outcomes of laparoscopic esophagomyotomy for achalasia in patients older than 60 years of age

Background  

The effectiveness of an esophagomyotomy for dysphagia in elderly patients with achalasia has been questioned. This study was designed to provide an answer.     

Management of anterior cruciate ligament rupture in patients aged 40 years and older

The aim of anterior cruciate ligament (ACL) reconstruction is essentially to restore functional stability of the knee and to allow patients to return to their desired work and activities. While in the young and active population, surgery is often the best therapeutic option after an ACL tear, ACL reconstruction in middle-aged people is rather more controversial due to concerns about a higher complication rate. The purpose of our article is to establish, through a systematic review of the literature, useful decision-making criteria for the management of anterior cruciate ligament rupture in patients aged 40 years and older, guiding surgeons to the most appropriate therapeutic approach. Various reports have shown excellent results of ACL reconstruction in patients over the age of 40 in terms of subjective satisfaction, return to previous activity level, and reduced complication and failure rates. Some even document excellent outcomes in subjects of 50 years and older. Although there are limited high-level studies, data reported in the literature suggest that ACL reconstruction can be successful in appropriately selected, motivated older patients with symptomatic knee instability who want to return to participating in highly demanding sport and recreational activities. Deciding factors are based on occupation, sex, activity level of the subject, amount of time spent performing such highly demanding activities, and presence of associated knee lesions. Physiological age and activity level are more important than chronological age as deciding factors when considering ACL reconstruction.     

Effects of knee extensor muscle strength on the incidence of osteopenia and osteoporosis after 6 years

The association of knee extensor muscle strength with bone mineral density (BMD) has been reported in cross-sectional epidemiological studies, but it remains unclear whether or not this is the case with longitudinal change. Thus, we investigated whether or not the knee extension strength can predict the incidence of osteopenia or osteoporosis after 6 years, then compared the difference between sexes. Subjects were 1255 community-dwelling Japanese men and menopaused women, aged 40–81 years. BMD of lumbar spine and femoral neck was assessed by dual-energy X-ray absorptiometry twice at 6-year intervals. Subjects were divided into three groups, normal, osteopenia, and osteoporosis, depending on their young adult mean BMD % value. In the cross-sectional analysis the correlations between the knee extension strength and BMD of the two regions were examined, using Pearson’s correlation coefficient. Longitudinal analyses were then conducted to determine the odds ratio, controlled for age and BMI, given that those who were normal in the initial stage developed osteopenia or osteoporosis after 6 years, for every 1 SD decrease in knee extension strength, as well as those who first had normal or osteopenia and then developed osteoporosis. Cross-sectional analysis showed a statistically significant relation between knee extensor muscle strength and BMD at both the lumbar spine (p = 0.02) and the femoral neck (p < 0.0001) only in men. The longitudinal analysis showed the significant effect of muscle strength on the loss of femoral neck BMD from normal to osteopenia or osteoporosis both in men (OR 1.84, 95 % CI 1.36–2.48, p < 0.0001) and in women (OR 1.29, 95 % CI 1.002–1.65, p < 0.05), as well as on the loss of spinal BMD from normal or osteopenia to osteoporosis only in men (OR 2.97, 95 % CI 1.07–8.23, p < 0.05). The results suggest the importance of knee extension strength to maintain the bone health of the proximal femur and spine in aging particularly in men.     

Perioperative and long-term outcomes after pancreaticoduodenectomy in elderly patients 80 years of age and older

Purpose

Although a pancreaticoduodenectomy (PD) has been recently regarded as a safe surgical procedure at high-volume centers, the efficacy of PD for patients 80 years of age and older is controversial. The aim of this study was to evaluate the perioperative and long-term outcomes following PD in patients 80 years of age and older.

Methods

Elderly patients 80 years of age and older who underwent PD between 2001 and 2009 were identified. The perioperative and long-term outcomes were compared with patients younger than 80 years of age.

Results

Of 561 total patients, 22 patients (3.9 %) were 80 years of age or older. Mortality occurred in one patient (4.5 %). Postoperative major complications (Clavien–Dindo classification ≥grade III) occurred in six patients (27.3 %) in this group, which was significantly higher than in patients younger than 80 years of age (P?=?0.008). The survival of the elderly patients undergoing PD for pancreatic cancer was significantly shorter than that for the same patient group with other diseases (median survival, 13 versus 82 months; P?=?0.014). Only one elderly patient with pancreatic cancer survived more than 3 years.

Conclusions

PD for pancreatic cancer in patients aged 80 and older should be carefully selected, because it is associated with a higher incidence of severe postoperative complications and a small change of long-term survival.     

A retrospective and consecutive analysis of the epidemiology and management of spinal cavernomas over the last 20 years in a single center

Spinal cavernous malformations (SCM) are rare lesions often presenting with acute onset of symptoms and progressive neurological deterioration due to hemorrhage into the spinal cord. With the aid of modern techniques, their surgical removal became much safer. The present study was undertaken to analyze the outcome of our series of surgically and conservatively treated patients with SCM. Over a period of 20 years, 20 surgically treated and 5 conservatively managed patients with spinal cavernous malformations were identified and enrolled into this analysis. Demographic data, clinical symptoms, localization and extension of the cavernoma, as well as pre- and postoperative neurological status were obtained. The clinical status was assessed using the Frankel score. Patients were followed up clinically and by MRI. Before surgery, 90 % (18/20) of our surgical patients were classified as Frankel D (93.8 %), whereas two patients (10 %) were graded C. None of the patients had a worse Frankel score at the time of discharge. Eighty percent of them (16 cases) remained unchanged, and 20 % (4 patients) improved during the first follow-up (mean 6.3 months, range 2–17 months). All improved patients had a superficially located SCM and were operated early (≤3 months). No worsening was observed during extended follow-up (range 9–134 months, mean 44.7 months). Five nonsurgically treated patients showed no significant clinical deterioration over a period of 6.7 years (mean, range 2.9–8 years). SCM localization and number of involved segments had no influence on outcome. Our data show that SCM can be resected with favorable neurological outcome by using intraoperative neuromonitoring. Within the follow-up period, patients treated conservatively remained in a stable neurological condition.     

Subtalar dislocation: two cases requiring surgery and a literature review of the last 25 years

Background

Subtalar dislocations are uncommon, representing ~1 % of all traumatic dislocations. We present two cases of closed medial subtalar dislocation and a systematic literature review of the last 25 years.

Methods

We performed an Embase, Medline, Pubmed and Cochrane search of the literature written in English between January 1988 and December 2012. Keywords used were subtalar, peritalar, subastragalar, luxatio pedis sub talo, dislocation and dislocations. All articles presenting original patient data were included. All available data regarding gender, age, direction, affected side, open or closed injury, accompanying fractures, reduction, time of immobilization and outcomes were collected in a database.

Results

Seventy-six articles were included with a total of 528 reported cases. Males (318/419 = 76 %) and the right foot (122/200 = 61 %) were affected more often than females and the left foot. Average age was 33.8 years (range 19 months–86 years). Cause of injury was a traffic accident in 43.7 % (157/359), a fall in 32.9 % (118/359), sports injuries in 13.9 % (50/359), sprain injuries in 5.3 % (19/359) and other causes in 4.2 % (15/359). The direction of the dislocation was medial in 71.5 % (352/492), lateral in 26.0 % (128/492), posterior in 1.6 % (8/492) and anterior in 0.8 % (4/492). Open dislocation was reported in 22.5 % (67/298). In 61.4 % (216/352) an additional osseous injury was diagnosed. Closed reduction was unsuccessful in 14.0 % (51/364) requiring immediate open reduction. Overall outcomes in the literature were good in 52.3 % (172/329), fair in 25.2 % (83/329) and poor in 22.5 % (74/329).

Failure to perceive increased risk of fracture in women 55?years and older: the Global Longitudinal Study of Osteoporosis in Women (GLOW)

Summary

We compared self-perception of fracture risk with actual risk among 60,393 postmenopausal women aged ??55?years, using data from the Global Longitudinal Study of Osteoporosis in Women (GLOW). Most postmenopausal women with risk factors failed to appreciate their actual risk for fracture. Improved education about osteoporosis risk factors is needed.

Introduction

This study seeks to compare self-perception of fracture risk with actual risk among postmenopausal women using data from GLOW.

Methods

GLOW is an international, observational, cohort study involving 723 physician practices in 17 sites in ten countries in Europe, North America, and Australia. Participants included 60,393 women ??55?years attended by their physician during the previous 24?months. The sample was enriched so that two thirds were ??65?years. Baseline surveys were mailed October 2006 to February 2008. Main outcome measures were self-perception of fracture risk in women with elevated risk vs women of the same age and frequency of risk factors for fragility fracture.

Results

In the overall study population, 19% (10,951/58,434) of women rated their risk of fracture as a little/much higher than that of women of the same age; 46% (27,138/58,434) said it was similar; 35% (20,345/58,434) believed it to be a little/much lower. Among women whose actual risk was increased based on the presence of any one of seven risk factors for fracture, the proportion who recognized their increased risk ranged from 19% for smokers to 39% for current users of glucocorticoid medication. Only 33% (4,185/12,612) of those with ??2 risk factors perceived themselves as being at higher risk. Among women reporting a diagnosis of osteopenia or osteoporosis, only 25% and 43%, respectively, thought their risk was increased.

Conclusion

In this international, observational study, most postmenopausal women with risk factors failed to appreciate their actual risk for fracture.     

Results of bipolar release in the treatment of congenital muscular torticolis in patients older than 10 years of age

Purpose  

Neglected congenital muscular torticollis (CMT) is a common presentation in developing countries like India, with the primary concern of the patients being cosmesis. Little has been published regarding the management of such patients. The aim of our study was to evaluate the results of bipolar release in this age group.
