Duration of fracture prevention after zoledronate treatment in women with osteopenia: observational follow-up of a 6-year randomised controlled trial to 10 years.

BACKGROUND: We previously identified that zoledronate administered at 18-month intervals reduced fragility fractures by a third in a 6-year trial of women older than 65 years with osteopenia. This extension aims to identify the persistence of these effects. METHODS: Of the 2000 ambulant, community dwelling, postmenopausal women older than 65 years recruited in Auckland, New Zealand, with T-scores at the total hip or femoral neck in the range -1·0 to -2·5, we invited participants who received four doses of intravenous zoledronate, completed follow-up to year 6 of the core trial, did not have metabolic bone disease (other than osteoporosis), and were not using bone-active drugs into this 4-year observational study extension, during which further treatment was at the discretion of their own doctors. Participants were asked to notify study staff of any new fractures and were telephoned at 7·5 years and 9·0 years to update their health status. Participants were then invited to an onsite visit at 10·0 years. Fractures and other health events were documented at each contact and analysed in all women who entered the extension, and bone mineral density (BMD; analysed in participants without notable use of bone-active medications who attended an onsite visit at 10 years) and turnover markers (measured from fasting morning blood in a random subset of 50 participants) were measured at year 10. FINDINGS: Of the 1000 women randomly assigned to receive zoledronate in the core trial, 796 participants were eligible for the extension, of whom 762 (96%) entered the extension between Sept 24, 2015, and Dec 13, 2017. Mean follow-up duration was 4·24 years (SD 0·57, range 0·61-6·55; final follow-up on May 25, 2022). 727 (91%) of participants were assessed at 10 years. 25 women died during the extension, six withdrew for medical reasons, and four were lost to follow-up. 92 women suffered 114 non-vertebral fractures during the extension. Non-vertebral fracture rates increased from a nadir of 15 fractures per 1000 woman-years (95% CI 10-21) in the last 2 years of the core trial to 24 fractures (17-33) in years 6-8 and 42 fractures (32-53) in years 8-10, similar to that in the placebo group in the last 2 years of the core trial. Total hip BMD (relative risk per 0·1 g/cm2 0·73, 95% CI 0·57-0·93; p=0·011) and a previous history of non-vertebral fracture (1·74, 1·12-2·69; p=0·013) at year 6 predicted incident fractures but change in total hip BMD did not. Total hip BMD decreased from 4·2% above study baseline to 0·8% above baseline (p<0·0001) during the extension. Turnover markers were not useful for predicting BMD loss in individuals. Osteonecrosis of the jaw or atypical femoral fractures did not occur in any participants. INTERPRETATION: The reduced fracture rates following zoledronate in the core trial were substantially maintained for 1·5-3·5 years after the last zoledronate infusion, but not thereafter.

Public awareness of childhood, teenager and young adult cancer signs and symptoms in Great Britain: a cross-sectional survey.

OBJECTIVES: To assess public awareness of the risks and symptoms of cancer in children, teenagers, and young adults (CTYA) aged <18 years in Great Britain. METHODS: A face-to-face computer-assisted opinion survey was conducted by Ipsos MORI. Participants were a population-based sample of 1000 adults (475 men, 525 women) aged >18 years, with 26% having children aged 6-15 in their households. Questions covered perception about cumulative cancer risk, confidence in recognising signs and symptoms, recognition and perceived urgency of classical signs and symptoms. RESULTS: Only 32% of respondents felt confident in recognising CTYA cancer signs and symptoms. Symptoms deemed to require medical assessment within 48 hours by over 50% of participants included seizures/fits, blood in urine or stool, and persistent vomiting. All symptoms except one were selected for assessment within 3 months. On average, respondents identified 10.6 out of 42 classical signs and symptoms. The most recognised symptoms included lump, swelling in pelvis, testicle or breast (46%), blood in urine or stool (44%), changes to moles (43%), lump/swelling in the chest wall or armpits (41%) and weight loss (40%). The least recognised symptoms were early/late puberty (10%), developmental delay in children aged <2 years (11%) and slow growth (13%), with 8%, 2% and 6%, respectively, perceiving no need to discuss them with a doctor. CONCLUSIONS: Public awareness of childhood cancer risks and symptoms is substantially lower compared with adult cancer awareness in Great Britain. These findings indicate knowledge and awareness gaps among the general public, highlighting the need for a child cancer awareness campaign.

Effects of elevated serum urate on cardiometabolic and kidney function markers in a randomised clinical trial of inosine supplementation.

In observational studies, serum urate positively associates with cardiometabolic and kidney diseases. We analyzed data from a randomised placebo-controlled trial to determine whether moderate hyperuricemia induced by inosine affects cardiometabolic and kidney function markers. One hundred and twenty post-menopausal women were recruited into a 6-month randomised, double-blind, placebo-controlled trial of inosine for bone health. Change from baseline in the following pre-specified endpoints was analyzed: body mass index; blood pressure; lipid profile; C-reactive protein; fasting glucose; insulin; HbA1c; serum creatinine; and estimated glomerular filtration rate (eGFR). Despite increases in serum urate levels (+ 0.17 mmol/L at week 6, P < 0.0001), no significant between-group differences were observed in cardiometabolic markers, with the exception of lower fasting glucose concentrations with inosine at week 19. In the inosine group, change in serum urate correlated with change in serum creatinine (r = 0.41, P = 0.0012). However, there was no between-group difference in serum creatinine values. Over the entire study period, there was no significant difference in eGFR (ANCOVA P = 0.13). Reduction in eGFR was greater in the inosine group at Week 13 (mean difference - 4.6 mL/min/1.73 m2, false detection rate P = 0.025), with no between-group difference in eGFR at other time points. These data indicate that increased serum urate does not negatively influence body mass index, blood pressure, lipid profile, or glycaemic control. Serum urate changes associated with inosine intake correlate with changes in serum creatinine, but this does not lead to clinically important reduction in kidney function over 6 months.Clinical trial registration number: Australia and New Zealand Clinical Trials Registry (ACTRN12617000940370), registered 30/06/2017.

Patient-reported experience of clinical care of osteogenesis imperfecta (OI) during the COVID-19 pandemic.

Background: Research on the effects of the COVID-19 pandemic on people with rare diseases is limited. Few studies compare healthcare throughout the progression of the ongoing pandemic. Aims: To assess the impact of the pandemic on individuals with osteogenesis imperfecta across two consecutive years, understand what challenges were encountered, and analyse the experience of remote consultation. Methods: An initial survey was distributed following the first lockdown in August 2020, and a second survey in April 2021. The surveys explored four themes- effects on therapy, alternatives to consultation, effect on mental health, and perceived risks of COVID-19. Results: In the 2020 survey, of the 110 respondents, 69 (63%) had at least one appointment delayed due to the lockdown, compared with 89 of the 124 respondents (72%) in 2021. Of the 110 respondents in 2020, 57 (52%) had a remote consultation, increasing to 92 of 124 (74%) in the follow-up survey. In the 2020 survey 63 of 91 respondents (69%) expressed anxiety due to lockdown, compared with 76 of 124 (61%) in 2021. The percentage of total respondents expressing a preference for remote consultation was 48% in 2020, increasing to 71% in 2021. Conclusions: The pandemic has had widespread effects on the mental and physical health of those with OI. These effects, alongside appointment delays, have increased as the pandemic progresses. Encouragingly, the increasing preference for remote consultation may indicate that this could be a viable long-lasting alternative to face-to-face appointments, especially for patients who previously traveled vast distances for specialist care.

Effect of Zoledronate on Lower Respiratory Infections in Older Women: Secondary Analysis of a Randomized Controlled Trial.

A recent observational study of the incidence of pneumonia in patients with previous hip fractures found that bisphosphonate use reduced pneumonia risk by about one-quarter, in comparisons with those either not receiving osteoporosis treatment or receiving treatment with non-bisphosphonate drugs. Mortality from pneumonia was similarly reduced. It was hypothesized that effects of these drugs on immune or inflammatory function might mediate this effect. We have used the adverse event database from our recent 6-year randomized controlled trial of zoledronate in 2000 women over the age of 65 years, to determine whether a similar effect is observed using this more rigorous study design. Seventy-five women had at least one episode of pneumonia (32 [3.2%] zoledronate, 43 [4.3%] placebo) and 119 women had at least one episode of either pneumonia or a lower respiratory tract infection (57 [5.7%] zoledronate, 62 [6.2%] placebo). There were 93 pneumonia events and 167 pneumonia/lower respiratory infection events. For pneumonia, the hazard ratio associated with randomization to zoledronate was 0.73 (95% confidence interval, 0.46-1.16; P = 0.18) and the rate ratio was 0.69 (0.45, 1.04; P = 0.073). For the composite endpoint of pneumonia or lower respiratory infection, the hazard ratio was 0.90 (0.61, 1.30; P = 0.58) and the rate ratio 0.74 (0.54, 0.997; P = 0.048). The proportion of people with events changed approximately linearly over time in both groups, suggesting a progressive divergence in cumulative incidence during the study. In conclusion, these findings lend support to the hypothesis that bisphosphonate use reduces the number of lower respiratory tract infections in older women, though the present study is under-powered for this endpoint and the findings are of borderline statistical significance. Further analysis of other trials of bisphosphonates is necessary to test this possibility further, and exploration of the possible underlying mechanisms is needed.

Elevated Urate Levels Do Not Alter Bone Turnover Markers: Randomized Controlled Trial of Inosine Supplementation in Postmenopausal Women.

OBJECTIVE: Observational studies have consistently demonstrated that serum urate level positively correlates with bone mineral density (BMD). We undertook this study to determine whether moderate hyperuricemia induced by inosine supplements influences bone turnover markers in postmenopausal women over a 6-month period. METHODS: One hundred twenty postmenopausal women were recruited for a 6-month randomized, double-blind, placebo-controlled trial. Key exclusion criteria were osteoporosis, previous fragility fracture, bisphosphonate therapy, gout, kidney stones, and a urine pH level of ≤5.0. Participants were randomized in a 1:1 ratio to receive placebo or inosine. The coprimary end points were change in levels of N-propeptide of type I procollagen (PINP) and change in levels of ß-C-telopeptide of type I collagen (ß-CTX). Change in BMD, as measured by dual x-ray absorptiometry, was an exploratory end point. RESULTS: Administration of inosine led to a significant increase in serum urate concentration over the study period (P < 0.0001 for all follow-up time points). At week 26, the mean change in serum urate concentration was +0.13 mmoles/liter (+2.2 mg/dl) in the inosine group and 0.00 mmoles/liter (0 mg/dl) in the placebo group. There was no difference in PINP or ß-CTX levels between groups over the 6 months. There were no significant changes in bone density between groups over the 6 months. Adverse events and serious adverse events were similar between the 2 groups. CONCLUSION: This clinical trial shows that although inosine supplementation leads to sustained increases in serum urate levels over a 6-month period, it does not alter markers of bone turnover in postmenopausal women. These findings do not support the concept that urate has direct biologic effects on bone turnover.

Predictors of Fracture in Older Women With Osteopenic Hip Bone Mineral Density Treated With Zoledronate.

A recent analysis has found that during treatment with denosumab, women attaining higher bone densities (BMD) are less likely to have incident fractures. We have reexamined this important question using data from our recent trial of zoledronate in osteopenic women. One thousand women randomized to treatment with zoledronate were followed for 6 years. Of those, 122 sustained fragility fractures during follow-up. Baseline age, nonvertebral fracture history, total hip BMD, and calculated fracture risk were all significantly different between those who had fractures during the study and those who did not. BMDs achieved during the study were higher in those without incident fractures. However, achieved BMDs were very closely related to baseline values (r = 0.93, p < 0.0001). The increase in BMD during zoledronate treatment was not different between those who had incident fractures and those who did not (0.15 < p < 0.78), and change in BMD was not predictive of fracture (univariate logistic regression analysis). Stepwise regression analysis of all baseline variables showed the best independent predictors of fracture to be age (odds ratio [OR] = 1.08, 95% confidence interval [CI] 1.04-1.13, p = 0.0003), baseline spine BMD (OR = 0.81, 95% CI 0.67-0.96, p = 0.016), and history of nonvertebral fracture (OR = 1.69, 95% CI 1.06-2.69, p = 0.028). Addition of change in BMD to this model did not improve its predictive power. If changes in BMD were included in the stepwise regression analysis of baseline variables, they did not emerge as significant predictors of fracture. It is concluded that age, fracture history, and baseline BMD determine the risk of new fractures. Differences in achieved BMD between those who do or do not fracture arise from the close relationship between baseline and achieved BMDs. These findings suggest that targeting any particular BMD during treatment is unlikely to be a useful or valid strategy. © 2020 American Society for Bone and Mineral Research (ASBMR).

Current Status and Best Practices of Shared Governance in US Pharmacy Programs.

Objective. To characterize shared governance in US schools and colleges of pharmacy and recommend best practices to promote faculty engagement and satisfaction. Findings. The literature review revealed only one study on governance in a pharmacy school and some data from an AACP Faculty Survey. Of the 926 faculty members who responded to the survey, the majority were satisfied or very satisfied with faculty governance (64%) and the level of input into faculty governance (63%) at their school. Faculty members in administrative positions and those at public institutions were more satisfied with governance. The forum resulted in the development of five themes: establish a clear vision of governance in all areas; ensure that faculty members are aware of their roles and responsibilities within the governance structure; ensure faculty members are able to join committees of interest; recognize and reward faculty contributions to governance; and involve all full-time faculty members in governance, regardless of their tenure status. Summary. Establishing shared governance within a school or college of pharmacy impacts overall faculty satisfaction and potentially faculty retention.

Study Behaviors Associated with Student Pharmacists' Academic Success in an Active Classroom Pharmacy Curriculum.

Objective. To identify the specific study behaviors that promoted student pharmacists' success in an active-learning pharmacy curriculum. Methods. The Washington State University College of Pharmacy and Pharmaceutical Sciences implemented an active-learning, flipped classroom model for instruction to equitably deliver course content to Doctor of Pharmacy students on both its main and extended campuses. Students' ability to adapt to the new model and its impact on their study behaviors were unknown. A qualitative descriptive design that included semi-structured interviews was applied to evaluate the study behaviors of high-performing students. The study sample included 13 third and fourth professional year pharmacy students in the top 20% of their respective classes. Results. Interview responses were unaffected by baseline demographics such as gender and year of graduation. Content analysis generated five primary themes related to the behavioral strategies used by high performers: preparing for class, preparing for testing, seeking help, knowing yourself, and building on strengths. These were mapped to the four tenants of Wenger's social learning theory in the representation of findings: learning as doing, learning as belonging, learning as becoming, and learning as experience. Conclusion. High-performing students demonstrated a refined ability to select and modify study behaviors that aided in their academic success, demonstrating a high degree of metacognition. The results of this research may assist pharmacy faculty members in identifying critical elements for success of students enrolled in pharmacy programs using an active learning model.

A student initiative to implement peer-led study groups for a pharmacogenomics course: Evaluation of student performance and perceptions.

INTRODUCTION: To better elucidate the impact of cooperative learning outside the classroom, a student-initiated research project was conducted to explore the effects of participating in peer-led study groups (PLSGs) on student examination scores and perceptions. METHODS: First-year pharmacy students were given the opportunity to participate in weekly PLSGs for a pharmacogenomics course during spring 2016 and spring 2017. Student exam performance was stratified by those who attended vs. those who did not. Optional pre- and post-course surveys examined student perceptions of PLSGs. RESULTS: No significant differences were seen between the attendance groups in spring 2016. In spring 2017, student attendees were significantly more likely to pass two of their six exams (p = .04, p = .0029) and to have higher exam scores on one exam (p = .02) in comparison to non-attendees. Overall exam score averages were significantly different between attendees and non-attendees during spring 2017 (p = .03) but not during spring 2016 (p = .38). Perception surveys indicated students believed participation helped them to demonstrate competency and build confidence. Additionally, students reported they felt more comfortable clarifying questions during the study groups vs. during class time. CONCLUSIONS: The impact of study group participation on student exam performance was minimal over the two years of data collection, but there were instances where exam scores were positively impacted. Students perceived value in study group participation even if it did not translate directly to improved exam performance on all exams.

Zoledronate Slows Weight Loss and Maintains Fat Mass in Osteopenic Older Women: Secondary Analysis of a Randomized Controlled Trial.

Studies in mice have suggested that osteocalcin plays an important role in glucose and fat metabolism. Since anti-resorptive drugs reduce circulating levels of osteocalcin they might be associated with increased fat mass and an increased risk of diabetes. Positive changes in body weight have been found in trials of alendronate and denosumab, but no significant effect in a previous trial of zoledronate. Whether those weight differences were in fat or lean mass is unknown. There were no effects of anti-resorptive treatments on fasting glucose concentrations or incidence of diabetes in those three studies. We have used our recent trial comparing zoledronate and placebo over 6 years in 2000 older osteopenic women to re-examine these questions. Both treatment groups lost body weight during the study (placebo 1.65 kg, zoledronate 1.05 kg), and this was significantly greater in the placebo group (P = 0.01). Both groups lost lean mass, and this loss was marginally (0.17 kg) but significantly (P = 0.02) greater in those receiving zoledronate. The placebo group had a mean loss of fat mass of 0.63 kg but there was no change in fat mass in the zoledronate group (between-groups comparison, P = 0.007). In the placebo group, there were 20 new diagnoses of diabetes, and in the zoledronate group, 19 (P = 0.87). Zoledronate prevented age-related loss of fat mass in these late postmenopausal women. The present study is the first to document a significant effect of zoledronate treatment on body weight, confirming results previously found with alendronate and denosumab. It also demonstrates that this is principally an effect to maintain fat mass rather than influencing lean mass, raising an important physiological question as to how anti-resorptive drugs have this effect on intermediary metabolism. It is possible that this anti-catabolic action contributes to the beneficial effects of anti-resorptive drugs on bone and longevity.

Effects of Zoledronate on Cancer, Cardiac Events, and Mortality in Osteopenic Older Women.

We recently showed that zoledronate prevented fractures in older women with osteopenia (hip T-scores between -1.0 and -2.5). In addition to fewer fractures, this study also suggested that women randomized to zoledronate had fewer vascular events, a lower incidence of cancer, and a trend to lower mortality. The present analysis provides a more detailed presentation of the adverse event data from that study, a 6-year, double-blind trial of 2000 women aged >65 years recruited using electoral rolls. They were randomly assigned to receive four infusions of either zoledronate 5 mg or normal saline at 18-month intervals. Supplements of vitamin D, but not calcium, were provided. There were 1017 serious adverse events in 443 participants in the placebo group, and 820 events in 400 participants in those randomized to zoledronate (relative risk = 0.90; 95% CI, 0.81 to 1.00). These events included fractures resulting in hospital admission. Myocardial infarction occurred in 39 women (43 events) in the placebo group and in 24 women (25 events) in the zoledronate group (hazard ratio 0.60 [95% CI, 0.36 to 1.00]; rate ratio 0.58 [95% CI, 0.35 to 0.94]). For a prespecified composite cardiovascular endpoint (sudden death, myocardial infarction, coronary artery revascularization, or stroke) 69 women had 98 events in the placebo group, and 53 women had 71 events in the zoledronate group (hazard ratio 0.76 [95% CI, 0.53 to 1.08]; rate ratio 0.72 [95% CI, 0.53 to 0.98]). Total cancers were significantly reduced with zoledronate (hazard ratio 0.67 [95% CI, 0.51 to 0.89]; rate ratio 0.68 [95% CI, 0.52 to 0.89]), and this was significant for both breast cancers and for non-breast cancers. Eleven women had recurrent or second breast cancers during the study, all in the placebo group. The hazard ratio for death was 0.65 (95% CI, 0.40 to 1.06; p = 0.08), and 0.51 (95% CI, 0.30 to 0.87) in those without incident fragility fracture. These apparent beneficial effects justify further appropriately powered trials of zoledronate with these nonskeletal conditions as primary endpoints. © 2019 American Society for Bone and Mineral Research.

Qualitative Assessment of Emotion Regulation Strategies for Prevention of Health Risk Behaviors in Early Adolescents.

The ability to regulate emotions has been linked to a variety of adolescent health risk behaviors, including sexual risk behaviors, especially for adolescents who are experiencing mental health symptoms. However, there is limited information available on intuitive emotion regulation strategies for early adolescents with mental health symptoms to facilitate the adaptation of emotion regulation interventions for psychopathology to health risk behavior prevention. For example, interventions to prevent sexual risk behaviors in early adolescence have yet to specifically target emotion regulation. This paper describes the use of focus groups to identify emotion regulation strategies that were understood by and acceptable to early adolescents with mental health symptoms who are also more likely to engage in risky health behaviors. Qualitative data were collected through focus groups (k=5 groups) with 15 early adolescents with mental health symptoms. The most commonly generated emotion regulation strategies were leaving the situation, distraction, physical release, expressing oneself to someone, positive thinking, and considering other options. Translation of these findings for use in preventive health-risk behavior interventions (including for sexual risk) is discussed.

Dietary Calcium Intake and Bone Loss Over 6 Years in Osteopenic Postmenopausal Women.

CONTEXT: Calcium intakes are commonly lower than the recommended levels, and increasing calcium intake is often recommended for bone health. OBJECTIVE: To determine the relationship between dietary calcium intake and rate of bone loss in older postmenopausal women. PARTICIPANTS: Analysis of observational data collected from a randomized controlled trial. Participants were osteopenic (hip T-scores between -1.0 and -2.5) women, aged >65 years, not receiving therapy for osteoporosis nor taking calcium supplements. Women from the total cohort (n = 1994) contributed data to the analysis of calcium intake and bone mineral density (BMD) at baseline, and women from the placebo group (n = 698) contributed data to the analysis of calcium intake and change in BMD. BMD and bone mineral content (BMC) of the spine, total hip, femoral neck, and total body were measured three times over 6 years. RESULTS: Mean calcium intake was 886 mg/day. Baseline BMDs were not related to quintile of calcium intake at any site, before or after adjustment for baseline age, height, weight, physical activity, alcohol intake, smoking status, and past hormone replacement use. There was no relationship between bone loss and quintile of calcium intake at any site, with or without adjustment for covariables. Total body bone balance (i.e., change in BMC) was unrelated to an individuals' calcium intake (P = 0.99). CONCLUSIONS: Postmenopausal bone loss is unrelated to dietary calcium intake. This suggests that strategies to increase calcium intake are unlikely to impact the prevalence of and morbidity from postmenopausal osteoporosis.

Fracture Prevention with Zoledronate in Older Women with Osteopenia.

BACKGROUND: Bisphosphonates prevent fractures in patients with osteoporosis, but their efficacy in women with osteopenia is unknown. Most fractures in postmenopausal women occur in those with osteopenia, so therapies that are effective in women with osteopenia are needed. METHODS: We conducted a 6-year, double-blind trial involving 2000 women with osteopenia (defined by a T score of -1.0 to -2.5 at either the total hip or the femoral neck on either side) who were 65 years of age or older. Participants were randomly assigned to receive four infusions of either zoledronate at a dose of 5 mg (zoledronate group) or normal saline (placebo group) at 18-month intervals. A dietary calcium intake of 1 g per day was advised, but calcium supplements were not provided. Participants who were not already taking vitamin D supplements received cholecalciferol before the trial began (a single dose of 2.5 mg) and during the trial (1.25 mg per month). The primary end point was the time to first occurrence of a nonvertebral or vertebral fragility fracture. RESULTS: At baseline, the mean (±SD) age was 71±5 years, the T score at the femoral neck was -1.6±0.5, and the median 10-year risk of hip fracture was 2.3%. A fragility fracture occurred in 190 women in the placebo group and in 122 women in the zoledronate group (hazard ratio with zoledronate, 0.63; 95% confidence interval, 0.50 to 0.79; P<0.001). The number of women that would need to be treated to prevent the occurrence of a fracture in 1 woman was 15. As compared with the placebo group, women who received zoledronate had a lower risk of nonvertebral fragility fractures (hazard ratio, 0.66; P=0.001), symptomatic fractures (hazard ratio, 0.73; P=0.003), vertebral fractures (odds ratio, 0.45; P=0.002), and height loss (P<0.001). CONCLUSIONS: The risk of nonvertebral or vertebral fragility fractures was significantly lower in women with osteopenia who received zoledronate than in women who received placebo.

Cancer-related cognitive impairment in breast cancer survivors: An examination of conceptual and statistical cognitive domains using principal component analysis.

There is a great deal of variability in the composition of neuropsychological test batteries used in the assessment of cancerrelated cognitive impairment (CRCI). Not only the development of a gold standard approach for CRCI assessment would allow for easier identification of women suffering from CRCI but it would also promote optimal care for survivors. As a first step towards the development of a valid and reliable unified test battery, the objective of this study was to verify whether the theoretical domains commonly used in CRCI assessment are statistically supported, before and after breast cancer treatment. Principal component analyses (PCA) were performed on the results from 23 neuropsychological tests grouped into eight conceptual domains. For baseline data, the Kaiser-Meyer-Olkin was .82 and Bartlett's X2(253, N=95) = 949.48, P<0.001. A five-component solution explained 60.94% of the common variance. For the post-treatment data, the Kaiser-Meyer-Olkin was .83 and Bartlett's X2(253, N=95) = 1007.21, P<0.001 and a five component solution explained 62.03% of the common variance. Although a visual comparison of the theoretical model with those determined via PCA indicated important overlap between conceptual domains and statistical components, significant dissimilarities were also observed.

It describes the development of a parish nursing service in Heartsease, Norwich, which complements community nursing practice by focusing on the importance of providing spiritual care alongside physical, psychological and social care. Case studies are provided to illustrate the benefits of a parish nursing service to individuals and the community.

Acute effects of calcium supplements on blood pressure and blood coagulation: secondary analysis of a randomised controlled trial in post-menopausal women.

Recent evidence suggests that Ca supplements increase the risk of cardiovascular events, but the mechanism(s) by which this occurs is uncertain. In a study primarily assessing the effects of various Ca supplements on blood Ca levels, we also investigated the effects of Ca supplements on blood pressure and their acute effects on blood coagulation. We randomised 100 post-menopausal women to 1 g/d of Ca or a placebo containing no Ca. Blood pressure was measured at baseline and every 2 h up to 8 h after their first dose and after 3 months of supplementation. Blood coagulation was measured by thromboelastography (TEG) in a subgroup of participants (n 40) up to 8 h only. Blood pressure declined over 8 h in both the groups, consistent with its normal diurnal rhythm. The reduction in systolic blood pressure was smaller in the Ca group compared with the control group by >5 mmHg between 2 and 6 h (P≤0·02), and the reduction in diastolic blood pressure was smaller at 2 h (between-groups difference 4·5 mmHg, P=0·004). Blood coagulability, assessed by TEG, increased from baseline over 8 h in the calcium citrate and control groups. At 4 h, the increase in the coagulation index was greater in the calcium citrate group compared with the control group (P=0·03), which appeared to be due to a greater reduction in the time to clot initiation. These data suggest that Ca supplements may acutely influence blood pressure and blood coagulation. Further investigation of this possibility is required.

The Effects of Re-challenge in Patients with a History of Acute Anterior Uveitis Following Intravenous Zoledronate.

To determine the incidence of adverse ocular side effects following re-challenge in patients who previously developed ocular symptoms following intravenous zoledronate. Secondary data analysis of a large, prospective, randomized, double-blind, placebo-controlled clinical trial was performed. Participants consisted of postmenopausal females with osteopenia randomized to placebo (N = 1000) or zoledronate 5 mg (N = 1001) intravenous infusion. Recruitment occurred over a 2-year period, with the first infusion being administered at recruitment, and subsequent infusions every 18 months. Eight participants developed acute anterior uveitis (AAU) (diagnosed by an ophthalmologist) following the first infusion of zoledronate. Following appropriate ophthalmic treatment, no patients had visual loss or other ocular sequelae. One further participant reported "sore red eyes" but did not attend for ophthalmology review. Six participants declined further infusions. The remaining three participants were administered two further zoledronate infusions, 18 months apart, and none developed any ocular symptoms following each infusion. As a precaution, two of these participants were examined by an ophthalmologist 3 days after their second infusion and neither had ocular symptoms or signs of AAU and no subsequent ocular side effects. AAU following zoledronate infusion is likely to be part of the acute phase response. If treated promptly under the care of an ophthalmologist, the visual prognosis is excellent. The results of this study suggest that the development of AAU should not be a contraindication to further infusion. However, in such cases, patients should be warned of the symptoms of AAU (ocular pain, redness, photophobia or blurred vision) and should be promptly referred to an ophthalmologist if symptoms develop.

Acute effects of calcium citrate with or without a meal, calcium-fortified juice and a dairy product meal on serum calcium and phosphate: a randomised cross-over trial.

Ca supplements, but not dietary Ca, have been associated with increased cardiovascular risk. This difference could be related to differences in their acute effects on serum Ca. We therefore examined the effects of Ca from different sources on serum Ca and phosphate in a randomised, cross-over trial of ten women (mean age of 69 years). Fasting participants received a single dose of 500 mg of Ca as citrate, citrate with a meal, fortified juice or a dairy product meal, with at least 6 d between each intervention. Blood was sampled before and 1, 2, 4 and 6 h after each intervention was ingested. Serum ionised and total Ca increased significantly from baseline over 6 h. Using calcium citrate fasting as a comparator, the elevations in ionised and total Ca were similar after fortified juice, delayed after calcium citrate with a meal and smaller after a dairy product meal. Serum phosphate and calcium-phosphate product increased from baseline after calcium citrate with a meal and after a dairy product meal, and they declined after calcium citrate fasting and after fortified juice. The elevations in serum Ca in the present study were only slightly different from those observed after the administration of 1000 mg of Ca in a previous study. These data indicate that different sources of Ca have different acute effects on serum Ca and support recommendations that dietary Ca might be safer than supplements. Whether these differences contribute to differences in cardiovascular risk requires further study.
