Abstract
BACKGROUND Care givers of Palliated patients are at risk of adverse physical, psychosocial and emotional sequelae in varied nature. Efficient and valid assessment tools facilitate early detection to take corrective measures. The Modified Caregiver Strain Index (MCSI), composed of domains associated with caregiver strain is a simple and brief tool that can be used in both clinical and field settings. This study aimed to adapt and validate this in order to cater effective palliative care services in Sri Lanka. METHODS After cross-cultural adaptation, 200 primary caregivers in 3 teaching hospitals were recruited. The internal consistency, item-total correlations, of the 13-item S-MCSI were performed. The criterion validity was assessed by Pearson correlation between the total scores of S-MCSI, the Karnofky Performance Scale and the Barthel index. Construct validity was determined by the principal component analysis keeping the Varimax with Keiser normalization as the rotation method. The Kaiser-Meyer-Olkin test (KMO) and Bartlett's test of sphericity statistics were also performed to determine the adequacy of the sample and correlations between items, respectively. The number of factors was determined by the Scree plot, percentage of variance explained by each component and number of Eigen values over 01 (Kaiser-Guttman rule). RESULTS The total MCSI score ranged 0 to 26. The overall Cronbach's alpha of the 13-item questionnaire was 0.80 while item-total corrections ranged 0.34 to 0.62, exception of one item (0.11). Inverse correlations were demonstrated in total scores of MCSI and Karnofky Performance Scale (r =- 0.32, p < 0.001) and Barthel index (r =-0.34, P < 0.001). A Kaiser-Meyer-Olkin value of 0.79 (p < 0.001) for Bartlett's test indicated adequate sampling and nonlinearity of factors. The Scree plot showed a three-factor structure explaining 57% of the variation. Items regarding personal wellbeing of caregiver loaded together while the effects on the family loaded separately. Adjustment of personal concerns and family issues along with time alteration grouped as the third factor. CONCLUSIONS The study showed that the Sinhala version of MCSI has adequate psychometric properties and reliability to be used as a validated tool to estimate the caregiver burden within a short time period for any health care workers.

Abstract
The dissolution behavior of calcium aluminosilicate based glass fibers, such as stone wool fibers, is an important consideration in mineral wool applications for both the longevity of the mineral wool products in humid environments and limiting the health impacts of released and inhaled fibers from the mineral wool product. Balancing these factors requires a molecular-level understanding of calcium aluminosilicate glass dissolution mechanisms, details that are challenging to resolve with experiment alone. Molecular dynamics simulations are a powerful tool capable of providing complementary atomistic insights regarding dissolution; however, they require force fields capable of describing not-only the calcium aluminosilicate surface structure but also the interactions relevant to dissolution phenomena. Here, a new force field capable of describing amorphous calcium aluminosilicate surfaces interfaced with liquid water is developed by fitting parameters to experimental and first principles simulation data of the relevant oxide-water interfaces, including ab initio molecular dynamics simulations performed for this work for the wüstite and periclase interfaces. Simulations of a calcium aluminosilicate surface interfaced with liquid water were used to test this new force field, suggesting moderate ingress of water into the porous glass interface. This design of the force field opens a new avenue for the further study of calcium and network-modifier dissolution phenomena in calcium aluminosilicate glasses and stone wool fibers at liquid water interfaces.

Abstract
BACKGROUND Osteoporosis and sarcopenia commonly coexist in older adults. There is strong evidence that bone and muscle impact each other through mechanical and biochemical cross-talk. OBJECTIVES We sought to investigate the relationship between the markers of bone remodeling including the C-terminal telopeptide of type 1 collagen (CTX) and procollagen type 1 N propeptide (P1NP) with muscle function, falls, and frailty in older women residing in long-term care (LTC) facilities. DESIGN A secondary analysis of a randomized controlled trial. SETTING Residents of LTC. PARTICIPANTS One hundred seventy-eight older women with osteoporosis. MEASUREMENTS We measured and analyzed baseline CTX, P1NP, gait speed, sit to stand time, history of falls, and frailty index. RESULTS Participants had a mean age of 86.7 years and BMI of 27.6 kg/m2. The correlation (r) of CTX with gait speed and sit to stand test, as indices for muscle function, were -0.193 (p=0.0163) and 0.152 (p=0.0507), respectively. Additionally, CTX level was significantly associated with history of falls (p=0.0068), recurrent falls (p=0.0260), and frail phenotype (p=0.0126). P1NP did not have a significant association with gait speed, sit to stand test, and history of falls; however, it was associated with frail phenotype (p=0.0137). Most findings persisted after adjusting for age. CONCLUSIONS In older women residing in LTC facilities, CTX was associated with gait speed, falls history, and frail phenotype, whereas P1NP was only associated with frail phenotype. These findings suggest a relationship between bone remodeling and muscle function.

Abstract
Abstract
Introduction
This study aimed assessed the prescribing quality of progesterone-only pills (POP) to determine whether online asynchronous algorithmic assisted consultations alone could help women or whether enhanced remote consultations still need to be performed. Our digital service follows Faculty of Sexual and Reproductive Healthcare FSRH clinical guidance, patients who have conditions that fall in category of UKMEC 3 and 4 would be signposted to other methods.1,2 The service works by patients completing an online consultation which is supported by algorithm-assisted consultations. The algorithm is written by doctors and pulls out the relevant information for the clinician to suggest whether it safe to prescribe. Asynchronized consultations using algorithms can identify patients for whom POP is not suitable to prescribe. As this is safe and scalable, it has the potential to improve access to contraception for women. For those women where technology identifies that POP is not suitable, there is still an important place for remote interaction to ensure that women are able to make an informed and safe contraceptive choice.
Aim
To review patients who met a Faculty of Sexual and Reproductive Healthcare (FSRH) exclusion for POP to determine adherence to FSRH clinical guidance on signposting these patients to in-person services where appropriate,1.2 and to review patients’ medical records, who were initially declined POP after completing an online consultation to identify the outcome and potential pathway improvement.
Methods
A retrospective case-note review of 362 patients, who met a FSRH exclusion criteria for POP, using a large digital sexual health service for POP (Cerelle, Cerazette, Norgeston, Noriday) between 1.3.21-25.5.22. Those patients who were not prescribed POP were then identified, to see how they were managed; how many were signposted to the clinic and how many were managed remotely and subsequently prescribed POP. The data underwent descriptive statistical analysis. Ethical approval was not required as this was a service evaluation.
Results
Of the 362 patients who met the FSRH exclusion criteria (100% female, aged 18-51), 288 (80%) patients were declined from POP treatment and signposted to in-persons services, 74 (20%) were prescribed POP after clinician review. Of the 288 who were initially declined POP, 110 (38%) patients sought further advice with a clinician remotely, resulting in 83 being prescribed POP and 27 being declined. Overall clinicians correctly followed guidance for 99% (284/288) of POP consultations who met the FSRH exclusion criteria.2 Of these 4 patients reported potential exclusion criteria for POP and were prescribed. Upon reflection, clinicians felt the potential exclusion criteria could have been explored further before prescribing.
Discussion/Conclusion
Asynchronous consultations bring lots of efficiencies, assists clinicians in triaging and managing the majority of patients. We’ve developed a pathway where patients can undertake a further discussion with a clinician remotely, which resulted in provision of remote contraception. This is convenient for patients and has the potential or may ease pressure off in-person services.

Abstract
Motile cilia on the cell surface generate movement and directional fluid flow that is crucial for various biological processes. Dysfunction of these cilia causes human diseases such as sinopulmonary disease and infertility. Here, we show that Ccdc108, a protein linked to male infertility, has an evolutionarily conserved requirement in motile multiciliation. Using Xenopus laevis embryos, Ccdc108 is shown to be required for the migration and docking of basal bodies to the apical membrane in epidermal multiciliated cells (MCCs). We demonstrate that Ccdc108 interacts with the IFT‐B complex, and the ciliation requirement for Ift74 overlaps with Ccdc108 in MCCs. Both Ccdc108 and IFT‐B proteins localize to migrating centrioles, basal bodies, and cilia in MCCs. Importantly, Ccdc108 governs the centriolar recruitment of IFT while IFT licenses the targeting of Ccdc108 to the cilium. Moreover, Ccdc108 is required for the centriolar recruitment of Drg1 and activated RhoA, factors that help establish the apical actin network in MCCs. Together, our studies indicate that Ccdc108 and IFT‐B complex components cooperate in multiciliogenesis.

Abstract
UNLABELLED Fracture prevention in cognitively impaired individuals is lacking. This work highlights the benefits of zoledronic acid on bone health in cognitively impaired older adults. Demonstrating benefits of therapy may increase treatment uptake and reduce fracture risk in this group. INTRODUCTION Osteoporosis has detrimental consequences for frail older adults. The effects on those with both osteoporosis and cognitive impairment are compounded due to increased risk of falls and changes in mobility, both of which can lead to fracture. However, there are limited data on treatment benefits for osteoporotic individuals with cognitive impairment. METHODS This post hoc, secondary analysis of data from a randomized, double-blind, placebo-controlled clinical trial of single-dose zoledronic acid included 179 women age ≥ 65 years residing in assisted living facilities or nursing homes, 43 of whom had mild to severe cognitive impairment. We assessed bone mineral density (BMD) of the total hip, femoral neck, and lumbar spine by dual-energy x-ray absorptiometry and serum bone turnover markers (C-terminal telopeptide of type I collagen and procollagen type I N propeptide) at 6 and 12 months. RESULTS In participants with cognitive impairment, those who received zoledronic acid had 4.3% greater BMD at the total hip (p=.005) and 5.3% greater BMD at the femoral neck (p<.001) after 12 months compared to those in the placebo group. Bone turnover markers demonstrated significant decreases at 6 months in those with cognitive impairment who received active treatment compared to the placebo group. Improvements in bone health measures with zoledronic acid were similar to those seen in participants without cognitive impairment. CONCLUSION Zoledronic acid improves bone health in frail older women with cognitive impairment similar to those without impairment. Further studies are warranted to assess the benefit for fracture reduction in this undertreated population.

Abstract
BACKGROUND Coexistence of osteoporosis and sarcopenia (osteosarcopenia), is associated with increased risk for fractures, falls, and mortality. Although there are multiple medications for management of osteoporosis, there are no approved pharmacotherapy for sarcopenia. OBJECTIVES We examined the effect of zoledronic acid on muscle mass indices including ALM (Appendicular Lean Mass) and ALM/Height2 in a cohort of older women with osteoporosis who were residents of Long-Term Care Communities (LTCCs). DESIGN A secondary analysis of a 2-year double-blind, randomized, placebo-controlled clinical trial. SETTING Residents of LTCCs. PARTICIPANTS Sixty-two postmenopausal women with osteoporosis. INTERVENTION Participants either received 5 mg infusion of zoledronic acid or placebo, once at the start of the study. MEASUREMENTS Participant's ALM/Height2, ALM, total hip BMD (Bone Mineral Density) and spine BMD were measured in 6, 12 and 24 months. RESULTS On average, participants were 86.7 years old and had a BMI of 27.4 kg/m2. There was no significant difference in change from baseline (mean ± SE) between the treatment group and the placebo group in ALM/Height2: (-0.15 vs -0.02, p = 0.541) and (-0.17 vs 0.001, p = 0.315) and (-0.29 vs -0.19, p = 0.646) or ALM: (-0.38 vs -0.09, p = 0.455) and (-0.45 vs -0.005, p = 0.216) and (-0.70 vs -0.48, p = 0.553) at 6, 12, and 24 months respectively. In addition, after adjusting for a possible confounding, the ALM/Height2 or ALM did not have significant improvements from baseline at 6 months, 12 months, and 24 months either in the treatment group or in the placebo group. However, there were significant improvements in the BMD at the total hip and the spine in the treatment group compared with the placebo group at all three time points. CONCLUSIONS Among older women residing in LTCCs, a single dose of zoledronic acid did not increase ALM/Height2 and ALM, despite improving the BMD at the total hip and the spine at the 2-year follow-up.

Abstract
Genome-wide association studies (GWASs) have discovered 20 risk loci in the human genome where germline variants associate with risk of pancreatic ductal adenocarcinoma (PDAC) in populations of European ancestry. Here, we fine-mapped one such locus on chr16q23.1 (rs72802365, p = 2.51 × 10-17, OR = 1.36, 95% CI = 1.31-1.40) and identified colocalization (PP = 0.87) with aberrant exon 5-7 CTRB2 splicing in pancreatic tissues (pGTEx = 1.40 × 10-69, βGTEx = 1.99; pLTG = 1.02 × 10-30, βLTG = 1.99). Imputation of a 584 bp structural variant overlapping exon 6 of CTRB2 into the GWAS datasets resulted in a highly significant association with pancreatic cancer risk (p = 2.83 × 10-16, OR = 1.36, 95% CI = 1.31-1.42), indicating that it may underlie this signal. Exon skipping attributable to the deletion (risk) allele introduces a premature stop codon in exon 7 of CTRB2, yielding a truncated chymotrypsinogen B2 protein that lacks chymotrypsin activity, is poorly secreted, and accumulates intracellularly in the endoplasmic reticulum (ER). We propose that intracellular accumulation of a nonfunctional chymotrypsinogen B2 protein leads to ER stress and pancreatic inflammation, which may explain the increased pancreatic cancer risk in carriers of CTRB2 exon 6 deletion alleles.

Abstract
Background Emerging cross-sectional reports find that the COVID-19 pandemic and related social restrictions negatively affect lifestyle behaviours and mental health in general populations. Aims To study the longitudinal impact of COVID-19 on work practices, lifestyle and well-being among desk workers during shelter-at-home restrictions. Methods We added follow-up after completion of a clinical trial among desk workers to longitudinally measure sedentary behaviour, physical activity, sleep, diet, mood, quality of life and work-related health using validated questionnaires and surveys. We compared outcomes assessed before and during COVID-19 shelter-at-home restrictions. We assessed whether changes in outcomes differed by remote working status (always, changed to or never remote) using analysis of covariance (ANCOVA). Results Participants (N = 112; 69% female; mean (SD) age = 45.4 (12.3) years; follow-up = 13.5 (6.8) months) had substantial changes to work practices, including 72% changing to remote work. Deleterious changes from before to during shelter-at-home included: 1.3 (3.5)-h increase in non-workday sedentary behaviour; 0.7 (2.8)-point worsening of sleep quality; 8.5 (21.2)-point increase in mood disturbance; reductions in five of eight quality of life subscales; 0.5 (1.1)-point decrease in work-related health (P < 0.05). Other outcomes, including diet, physical activity and workday sedentary behaviour, remained stable (P ≥ 0.05). Workers who were remote before and during the pandemic had greater increases in non-workday sedentary behaviour and stress, with greater declines in physical functioning. Wake time was delayed overall by 41 (61) min, and more so in workers who changed to remote. Conclusions Employers should consider supporting healthy lifestyle and well-being among desk workers during pandemic-related social restrictions, regardless of remote working status.

Abstract
The results of the sharp trial established sorafenib, a tyrosine kinase inhibitor (tki), as the sole first-line treatment option in advanced hepatocellular carcinoma (hcc) for more than a decade. In 2020, there has been a surge in new therapies for hcc, including immunotherapeutic strategies and the approval of a number of novel tkis. In addition to sorafenib, lenvatinib and combination atezolizumab-bevacizumab now represent standard first-line treatment options. As those systemic therapy options begin to be better utilized, assurance of adequate liver function and optimal timing are required to improve patient outcomes. Furthermore, sequencing of the agents will have to be carefully tailored, given the increasing armamentarium of choices. Here, we discuss the role of lenvatinib and sorafenib in the first-line management of hcc.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
Background:ANCA-associated Vasculitis (AAV) is a rare, severe small vessel vasculitis that affects multiple organs with a high acute mortality risk. As every patient presents differently, diagnosis is often delayed. Although treatments exist, responses vary, and remission is often not achieved or sustained. From the time of initial diagnosis onwards, patients suffer from an impaired quality of life. Coping with pain, fatigue, ongoing symptoms and combating challenges becomes a complex task and patients may be challenged in how best to communicate these emotions with health care professionals. We aimed to develop an initiative with Art and Voice, that would seek to empower people living with AAV and their carers in feeling understood, seen and heard in a meaningful way. This would invite a collective understanding of ‘how people make sense of key life experiences and what it means to them’ by creating a common language to address poorly addressed issues.Objectives:This project aims to provide a voice to patients to express personal experiences and complexity of everyday living and empower people to feel in control of their own health through an online platform. It should also allow practitioners to gain new awareness about issues faced by their patients, to better understand the relationships between caring and curing, hearing and listening.Methods:We collaborated with 10 patient association groups representatives, 17 AAV patients and 9 of their carers across 7 European countries. A series of workshops were set up to discuss issues faced and aid the subsequent production of a range of materials designed to provide clear, comprehensive content that would help individuals cope with the physical and emotional impact of AAV from diagnosis to living with it. This work was supported by a digital artist who is a rheumatologist living with vasculitis.Results:The co-creation of patient information materials featuring real life patients was successful and led to the development of a creative initiative called SEE ME.HEAR ME with an online platformwww.myancavasculitis.com. This includes: (1) an awareness programme featuring artwork created by the digital artist and advised by the patients which captures the essence of AAV from the patients view (see Figure). (2) a series of first-hand patient and carer stories capturing their authentic voice on ‘what it is like to live with the disease’. (3) extensive written content designed to fill information gaps around AAV diagnosis, investigations and treatment and what to expect during clinical follow up. The platform supports patients in asking questions and seeking information while signposting them to their own healthcare professional for advice and their local country patient association for support.Table 1.Sensitivities and specificities of examinations in gout and calcium pyrophosphate deposition diseaseConclusion:People with AAV need support throughout life, the profound psychosocial influence from illness makes the lived experience, challenging. SEE ME. HEAR ME online patient platform aims to generate awareness around AAV, improve physician and patient dialog, and enhance people’s experiences of living and coping with the disease. In addition it provides support for carers and giving valuable insights to friends, family and the general public about what the lived experience with AAV looks like.Acknowledgments:We wish to thank all European patients and patient association leads who worked on this projectDisclosure of Interests:Shanali Perera Consultant of: Vifor Pharma, Dijana krafcsik Employee of: Vifor Pharma, Peter Rutherford Shareholder of: Vifor Pharma, Employee of: Vifor Pharma, Baxter Healthcare

Abstract
For clinical studies of sarcopenia and frailty, clinically meaningful outcome measures are needed to monitor disease progression, evaluate efficacy of interventions, and plan clinical trials. Physical performance measures including measures of gait speed and other aspects of mobility and strength have been used in many studies, although a definition of clinically meaningful change in performance has remained unclear. The International Conference on Frailty and Sarcopenia Research Task Force (ICFSR-TF), a group of academic and industry scientists investigating frailty and sarcopenia, met in Miami Beach, Florida, USA in February 2019 to explore approaches for establishing clinical meaningfulness in a manner aligned with regulatory authorities. They concluded that clinical meaningful change is contextually dependent, and that both anchor-based and distribution-based methods of quantifying physical function are informative and should be evaluated relative to patient-reported outcomes. In addition, they identified additional research needed to enable setting criteria for clinical meaningful change in trials.

Abstract
Serum starvation stimulates cilia growth in cultured cells, yet serum factors associated with ciliogenesis are unknown. Previously, we showed that starvation induces rapid Rab11-dependent vesicular trafficking of Rabin8, a Rab8 guanine-nucleotide exchange factor (GEF), to the mother centriole, leading to Rab8 activation and cilium growth. Here, we demonstrate that through the LPA receptor 1 (LPAR1), serum lysophosphatidic acid (LPA) inhibits Rab11a-Rabin8 interaction and ciliogenesis. LPA/LPAR1 regulates ciliogenesis initiation via downstream PI3K/Akt activation, independent of effects on cell cycle. Akt stabilizes Rab11a binding to its effector, WDR44, and a WDR44-pAkt-phosphomimetic mutant blocks ciliogenesis. WDR44 depletion promotes Rabin8 preciliary trafficking and ciliogenesis-initiating events at the mother centriole. Our work suggests disruption of Akt signaling causes a switch from Rab11-WDR44 to the ciliogenic Rab11-FIP3-Rabin8 complex. Finally, we demonstrate that Akt regulates downstream ciliogenesis processes associated with Rab8-dependent cilia growth. Together, this study uncovers a mechanism whereby serum mitogen signaling regulates Rabin8 preciliary trafficking and ciliogenesis initiation.

Abstract
OBJECTIVE To compare predeparture tuberculosis (TB) screening policies, including screening criteria and screening tests, and visa requirements for prospective migrants to high-income countries that have low to intermediate TB incidence and high immigration. STUDY DESIGN Systematic review of policy documents. METHODS We systematically identified high-income, high net-migration countries with an estimated TB incidence of <30 per 100,000. After initial selection, this yielded 15 countries which potentially had TB screening policies. We performed a systematic search of governmental and official visa services' websites for these countries to identify visa information and policy documents for prospective migrants. Results were summarized, tabulated, and compared. RESULTS Programs to screen for active TB were identified in all 15 countries, but screening criteria and screening tests varied substantially between countries. Prospective migrants' country of origin represented an initial assessment criterion which generally focused on elevated TB incidence based on World Health Organization data but also focused on the countries of origin that sent the most migrants, and this varied between destination countries. Specific categories of migrants represented a second assessment criterion that focused on duration of stay and reasons for migration; the focus of which showed variation between the destination countries. Specific screening tests including medical examination and chest X-rays were used as the final stage of assessment, and there were differences between which tests were used between the destination countries. CONCLUSIONS Current approaches to migrant TB screening are inconsistent in their approach and implementation. While this variation might reflect adaptation to local public health situations, it could also indicate uncertainty concerning optimal strategies. Comparative research studies are needed to define the most effective and efficient methods for TB screening of migrants.

Abstract
Background: Sri Lanka is facing epidemiologic transition from communicable diseases to noncommunicable diseases in recent decades. Aim: This study analyses the trends in incidence and mortality of all cancers, breast cancer, cervical, ovarian and uterine cancers among Sri Lankan females over 1995-2010. Methods: Cancer incidence was obtained from the published national hospital based cancer registries, Sri Lanka for 1995-2010. Cancer mortality was abstracted from World Health Organization (WHO) database for 1996-2003 and 2006 and Department of Census and Statistics Sri Lanka for 1995 and 2004-2010 where WHO data were not available. Number of new cases and deaths were obtained by five-year age group for all cancers by sex and breast, cervical, ovarian and uterine cancers for females. Particular cancer specific incidence and mortality rates were directly age-standardized to the world population and age standardized rates were calculated for all ages, 20-34, 35-64 and over 64 years. Results: Female, age-standardized rates (ASR) for incidence for all cancers rose from 63.3 to 87.5 per 100 000 population during 1995-2010 and morality increased from 44.5 to 53.5 per 100 000 population over 1995-2010. In spite of having basically similar trends in both sexes, female incidence remained higher and mortality lower than males. Breast cancer was the commonest cancer among females with its incidence and mortality increasing through-out. Cervical cancer incidence increased during 1995- 2000, declined slightly in 2005 and remained stable over 2006-2010. Cervical cancer mortality remained stable over 1995-1999, declined in 1999-2003, increased in a lesser extend throughout 2003-2006 and remained stable during 2007-2010. Ovarian cancer incidence remained stable over 1995-2010 with 35-64 years being highest. Its mortality remained stable over 1995-2000 and declined slightly during 2000-2003 and increased in 2003-2010 with over 64 years being highest. Uterine cancer incidence and mortality increased steadily throughout 1995-2010. For all above mentioned cancers, incidence and mortality in 0-34 years remained low. Conclusion: Increasing trend of cancer incidence and mortality among females over 1995-2010, directs the need of revisiting breast cancer and cervical cancer control program in the country and strengthening awareness and early diagnosis and timely treatment of the other gynecologic cancers.

Methods: A descriptive cross sectional study was conducted to assess five-year survival among cervical cancer patients of the western province, diagnosed in 2008, from hospital based cancer registry. Ethical clearance was from Ethical Review Committee of Faculty of Medicine, University of Colombo. Study sample consisted of 177 patients who were eligible. Two pretested data records sheets were used. Patient contact details, incident date, clinical stage, histology treatment details, last contact date and survival status at the last contact date were abstracted from the hospital records. Data abstraction from the hospital records were conducted by medical officers. Patients were followed-up at the field by the public health nursing sisters to assess survival-status and associated prognostic factors in 2014. Statistical analysis was conducted using Stata-12. Observed survival rates were calculated using Kaplan-Meier product-limit method. Survival time was limited only for the five years from the incidence date. Survival at 1, 3 and 5 years were calculated. Log-rank test was used in univariate analysis to identify. Potentially important prognostic variables were identified using log-rank test in univariate analysis. Cox-proportional hazards model was used in multivariate analysis using covariates found to be with probability of 0.2 or below in log-rank test. Results: Mean age of the total of 177 eligible patients was 56.3 years (SD=12.4). Majority 79 (44.6%) were from Colombo district. Sixty one (34.5%) and thirty seven (20.9%) were from Gampaha and Kalutata districts respectively. Seventy (56.0%) were in stage IIIA and B. Most 42 (31.8%) had radiotherapy as first treatment while 24 (18.2%) had chemo-radiation, 17 (12.9%) had chemotherapy and 17 (12.9%) had surgery. Thirty-four (24.2%) had other options as first line. Forty-one (23.1%) had experienced the death within the five-year period from the incidence-date. One, three and five year survivals were 86.0%, 70.0% and 62.5% respectively. District, clinical stage, undergone surgery were statistically significant in univariate analysis ( P < 0.05). Only clinical stage was found to be significant in multiple cox- regression( P < 0.05). Women in stage III & IV were 3.5 times more likely to die compared with those in stage I and II at diagnosis. Conclusion: Cervical cancer patients had fairly good five-year survival (62.5%). Late clinical stage being poor prognostic factor reflects the need of strengthening prevention, screening and palliative care.

Abstract
UNLABELLED The Fracture Improvement with Teriparatide (Fix-IT) study randomized 13 women with an atypical femur fracture to immediate vs delayed teriparatide therapy; all were followed for 12 months. Results suggested a trend for superior healing and lesser bone mineral density declines in the immediate vs delayed group with no differences in adverse events. PURPOSE Little clinical data are available on the use of teriparatide for the treatment of bisphosphonate-associated atypical femur fractures (AFF). The goal of the Fix-IT study was to determine if immediate therapy with teriparatide was superior for fracture healing after an AFF compared to a 6-month delay in teriparatide therapy. METHODS This randomized pilot clinical trial included 13 women with an AFF who were randomized to immediate teriparatide vs a delay of 6 months. All were followed for 12 months on teriparatide. The primary outcomes included individual and composite measures of radiologic bone healing (scored 1 point [no healing] to 4 points [complete healing]) at 6 and 12 months. Secondary outcomes included bone mineral density of the unfractured contralateral hip, spine, 1/3 distal radius, and adverse events. RESULTS We found there was a trend for superior healing with the composite score (12.6 vs 11.2 at 6 months and 15.4 vs 13.2 at 12 months), and lesser bone mineral density declines at the 1/3 distal radius (12-month change - 1.9 vs - 6.1%) in the immediate vs the delayed group. There were no differences in adverse events. There was one implant failure in the delayed group. CONCLUSIONS There is a preliminary signal for greater improvements with immediate teriparatide therapy vs delayed therapy. However, because an AFF is a rare event, and only a small number of patients were included, the results must be interpreted with caution.

Abstract
UNLABELLED We examined the impact of daily supplementation on vitamin D deficiency, function, and falls in female long-term care residents. Initial vitamin D deficiency was associated with greater functional decline and increased fall risk despite guideline-recommended supplementation, highlighting the importance of preventing vitamin D deficiency in frail elderly. INTRODUCTION Institute of Medicine (IOM) guidelines recommend 800 IU vitamin D daily for older adults and maintaining serum 25-hydroxyvitamin D [25(OH) D] above 20 ng/ml for optimal skeletal health. The adequacy of IOM guidelines for sustaining function and reducing falls in frail elderly is unknown. METHODS Female long-term care residents aged ≥65 enrolled in an osteoporosis clinical trial were included in this analysis (n = 137). Participants were classified based on baseline 25(OH) D levels as deficient (<20 ng/ml, n = 26), insufficient (20-30 ng/ml, n = 40), or sufficient (>30 ng/ml, n = 71). Deficient women were provided initial vitamin D repletion (50,000 IU D3 weekly for 8 weeks). All were supplemented with 800 IU vitamin D3 daily for 24 months. Annual functional assessments included Activities of Daily Living (ADLs), Instrumental ADL (IADL), physical performance test (PPT), gait speed, cognition (SPMSQ), and mental health (PHQ-9). We used linear mixed models for analysis of functional measures and logistic regression for falls. RESULTS Daily supplementation maintained 25(OH) D levels above 20 ng/ml in 95% of participants. All groups demonstrated functional decline. Women initially deficient had a greater decline in physical function at 12 (IADL -2.0 ± 0.4, PPT -3.1 ± 0.7, both p < 0.01) and 24 months (IADL -2.5 ± 0.6, ADL -2.5 ± 0.6, both p < 0.01), a larger increase in cognitive deficits at 12 months (1.7 ± 0.4: p = 0.01) and more fallers (88.5%, p = 0.04) compared to those sufficient at baseline, despite supplementation to sufficient levels. CONCLUSIONS IOM guidelines may not be adequate for frail elderly. Further study of optimal 25(OH) D levels for maintaining function and preventing falls is needed.

Abstract
WHAT IS KNOWN AND OBJECTIVE There are few studies examining both drug-drug and drug-disease interactions in older adults. Therefore, the objective of this study was to describe the prevalence of potential drug-drug and drug-disease interactions and associated factors in community-dwelling older adults. METHODS This cross-sectional study included 3055 adults aged 70-79 without mobility limitations at their baseline visit in the Health Aging and Body Composition Study conducted in the communities of Pittsburgh PA and Memphis TN, USA. The outcome factors were potential drug-drug and drug-disease interactions as per the application of explicit criteria drawn from a number of sources to self-reported prescription and non-prescription medication use. RESULTS Over one-third of participants had at least one type of interaction. Approximately one quarter (25·1%) had evidence of had one or more drug-drug interactions. Nearly 10·7% of the participants had a drug-drug interaction that involved a non-prescription medication. % The most common drug-drug interaction was non-steroidal anti-inflammatory drugs (NSAIDs) affecting antihypertensives. Additionally, 16·0% had a potential drug-disease interaction with 3·7% participants having one involving non-prescription medications. The most common drug-disease interaction was aspirin/NSAID use in those with history of peptic ulcer disease without gastroprotection. Over one-third (34·0%) had at least one type of drug interaction. Each prescription medication increased the odds of having at least one type of drug interaction by 35-40% [drug-drug interaction adjusted odds ratio (AOR) = 1·35, 95% confidence interval (CI) = 1·27-1·42; drug-disease interaction AOR = 1·30; CI = 1·21-1·40; and both AOR = 1·45; CI = 1·34-1·57]. A prior hospitalization increased the odds of having at least one type of drug interaction by 49-84% compared with those not hospitalized (drug-drug interaction AOR = 1·49, 95% CI = 1·11-2·01; drug-disease interaction AOR = 1·69, CI = 1·15-2·49; and both AOR = 1·84, CI = 1·20-2·84). WHAT IS NEW AND CONCLUSION Drug interactions are common among community-dwelling older adults and are associated with the number of medications and hospitalization in the previous year. Longitudinal studies are needed to evaluate the impact of drug interactions on health-related outcomes.

Abstract
Gait function is traditionally assessed using well-lit, unobstructed walkways with minimal distractions. In patients with subclinical physiological abnormalities, these conditions may not provide enough stress on their ability to adapt to walking. The introduction of challenging walking conditions in gait can induce responses in physiological systems in addition to the locomotor system. There is a need for a device that is capable of monitoring multiple physiological systems in various walking conditions. To address this need, an Android-based gait-monitoring device was developed that enabled the recording of a patient's physiological systems during walking. The gait-monitoring device was tested during self-regulated overground walking sessions of fifteen healthy subjects that included 6 females and 9 males aged 18-35 years. The gait-monitoring device measures the patient's stride interval, acceleration, electrocardiogram, skin conductance and respiratory rate. The data is stored on an Android phone and is analyzed offline through the extraction of features in the time, frequency and time-frequency domains. The analysis of the data depicted multisystem physiological interactions during overground walking in healthy subjects. These interactions included locomotion-electrodermal, locomotion-respiratory and cardiolocomotion couplings. The current results depicting strong interactions between the locomotion system and the other considered systems (i.e., electrodermal, respiratory and cardiovascular systems) warrant further investigation into multisystem interactions during walking, particularly in challenging walking conditions with older adults.

Abstract
BACKGROUND There are limited clinical data on enteric fever in the Pacific and New Zealand (NZ) compared with the Indian subcontinent (ISC) and South-East Asia (SEA). Our objective was to describe enteric fever in Auckland - a large Pacific city, focusing on disease acquired in these regions. METHODS We reviewed enteric fever cases hospitalised in Auckland from January 2005 to December 2010. RESULTS Microbiologically confirmed EF was identified in 162 patients. Travel regions: Pacific, 40 cases (25%) (Samoa, 38; Fiji, two), ISC, 72 (44%), SEA, seven (4%), other, three (2%), no travel, 40 (25%). Enteric fever rates for Auckland resident travellers were: India 50.3/100 000; Samoa 19.7/100 000.All Pacific cases were Salmonella Typhi. Of local isolates (without travel history), 38 were S. Typhi (36 fully susceptible, one multi-drug resistant (MDR) + nalidixic acid resistant (NAR), one unknown) and two S. Paratyphi (both NAR). Of non-Pacific travel, 56/82 (69%) isolates were S. Typhi, the remainder S. Paratyphi (15 isolates were fully susceptible, only 1% were MDR). Significant associations of serotype and antibiotic resistance with different travel regions and similarity of phage types (local and Pacific) were observed. Headache, vomiting and acute kidney injuries were more frequent with Pacific travel, while abdominal distension and cholecystitis with local disease. Shorter duration of treatment in the Pacific group was seen despite length of stay in hospital not being reduced. Local cases were associated with longer hospital admissions. CONCLUSIONS One half of cases in Auckland are acquired either from Pacific or locally. Similarities mean that disease acquired locally is likely of Pacific origin.

Abstract
UNLABELLED In postmenopausal women with low bone mass and hormone-receptor-positive breast cancer on an aromatase inhibitor, risedronate maintained skeletal health assessed by bone density and turnover markers. Women with the greatest decreases in bone turnover markers at 12 months had the greatest increases in bone density at 24 months. INTRODUCTION Aromatase inhibitors (AIs), adjuvant endocrine therapy for postmenopausal women with hormone-receptor-positive breast cancer, are associated with bone loss and fractures. Our objectives were to determine if (1) oral bisphosphonate therapy can prevent bone loss in women on an AI and (2) early changes in bone turnover markers (BTM) can predict later changes in bone mineral density (BMD). METHODS We conducted a 2-year double-blind, placebo-controlled, randomized trial in 109 postmenopausal women with low bone mass on an AI (anastrozole, letrozole, or exemestane) for hormone-receptor-positive breast cancer. Participants were randomized to once weekly risedronate 35 mg or placebo, and all received calcium plus vitamin D. The main outcome measures included BMD, BTM [carboxy-terminal collagen crosslinks (CTX) and N-terminal propeptide of type 1 procollagen (P1NP)], and safety. RESULTS Eighty-seven percent completed 24 months. BMD increased more in the active treatment group compared to placebo with an adjusted difference at 24 months of 3.9 ± 0.7 percentage points at the spine and 3.2 ± 0.5 percentage points at the hip (both p < 0.05). The adjusted difference between the active treatment and placebo groups were 0.09 ± 0.04 nmol/LBCE for CTX and 23.3 ± 4.8 μg/mL for P1NP (both p < 0.05). Women with greater 12-month decreases in CTX and P1NP in the active treatment group had a greater 24-month increase in spinal BMD (p < 0.05). The oral therapy was safe and well tolerated. CONCLUSION In postmenopausal women with low bone mass and breast cancer on an AI, the oral bisphosphonate risedronate maintained skeletal health.

Abstract
OBJECTIVE We conducted a survey of nursing home physicians to learn about (1) the laboratory value thresholds that clinical event monitors should use to generate alerts about potential adverse drug events (ADEs); (2) the specific information to be included in the alerts; and (3) the communication modality that should be used for communicating them. METHODS Nursing home physician attendees of the 2010 Conference of AMDA: The Society for Post-Acute and Long-Term Care Medicine. RESULTS A total of 800 surveys were distributed; 565 completed surveys were returned and seven surveys were excluded due to inability to verify that the respondents were physicians (a 70% net valid response rate). Alerting threshold preferences were identified for eight laboratory tests. For example, the majority of respondents selected thresholds of ≥5.5 mEq/L for hyperkalemia (63%) and ≤3.5 without symptoms for hypokalemia (54%). The majority of surveyed physicians thought alerts should include the complete active medication list, current vital signs, previous value of the triggering lab, medication change in the past 30 days, and medication allergies. Most surveyed physicians felt the best way to communicate an ADE alert was by direct phone/voice communication (64%), followed by email to a mobile device (59%). CONCLUSIONS This survey of nursing home physicians suggests that the majority prefer alerting thresholds that would generally lead to fewer alerts than if widely accepted standardized laboratory ranges were used. It also suggests a subset of information items to include in alerts, and the physicians' preferred communication modalities. This information might improve the acceptance of clinical event monitoring systems to detect ADEs in the nursing home setting.
