Synthesis and Characterization of Macrocyclic Chiral Tröger's Base Phenhomazine Candidates as Anticancer Agent.

1,4,7,10-Tetraoxa[10](2,8)trögerophane 5 was synthesized from its corresponding precursors. Heating of 2 with p-nitrophenoxide afforded bis(p-nitrophenyl)ether 3, which was treated with hydrazine hydrate to give bis(p-aminophenyl)ether 4. Treatment of 4 with paraformaldehyde and triflouroacetic anhydride gave trögerophane 5. Reaction of 5 with trifluroacetic anhydride afforded phenhomazine derivative 6, which was treated with potassium carbonate to afford tetrahydrophenhomazine 7. Finally, reaction of 7 with phenacylchloride, bromoacetic acid, or ethyl bromoacetate in the presence of triethyl amine under reflux, afforded the corresponding macrocyclic compounds 8, 9 and 10, respectively. The synthesized trögerophane,precursors and its newly synthesized phenhomazines derivatives were screened for anticancer activity. Results revealed that 1,4,7,10-tetraoxa[10](2,8)trögerophane had a promising selectivity towards colon cancer cell line with an IC50 of 92.7 µg/ml.

The "National Integrated Medical Imaging System" [NIMIS]-friend, not nimesis!

INTRODUCTION: The "National Integrated Medical Imaging System" or NIMIS went live in 2011 and allows the movement of patient radiology imaging throughout the Irish health system. At the time of its launch, NIMIS was not only going to allow the filmless passage of patient radiology imaging but it was also envisaged that it would act as a medical image archive. The aim of this study was to assess the awareness and use of non-consultant hospital doctors and hospital consultants with regard to this medical image archive/referral function of NIMIS. METHODS: A survey was carried out on 50 doctors across all specialities and grades at Tullamore Hospital looking at different aspects of the use of NIMIS. RESULTS: Ninety-four percent of respondents use NIMIS on a daily basis and 6% use it on a weekly basis. The primary reason for using NIMIS was found to be "Viewing and Ordering Imaging" in 92% of those surveyed with 8% stating it was "Viewing imaging/reports". Ninety-eight percent surveyed said they had never used NIMIS to send a referral form or clinical photograph and 82% were not aware of this potential function. The majority of those surveyed stated that they either agreed or strongly agreed NIMIS is user-friendly. CONCLUSION: NIMIS allows the safe and confidential flow of patient images and clinical information in the Irish health system. It could provide definite potential in the areas of clinical conferencing, multidisciplinary meetings and remote patient assessment along with collaborative research and education.

General practitioner attitudes and experiences of orthopaedic services in the Irish midlands.

INTRODUCTION: Disorders of the musculoskeletal system are the main cause of disability and lost working days worldwide, and osteoarthritis affects almost half a million people in Ireland. Appropriate access and resourcing of general practice and orthopaedics is a necessary measure for the provision of a safe and efficient health service. One area that remains particularly challenging in Ireland is that of outpatient waiting lists, and the purpose of this study was to assess the attitudes and experiences of general practitioners in the Irish midlands with regard to orthopaedic services and to evaluate these in the context of national strategies and international best practice. METHODS: A survey was sent to general practitioners in the midlands looking at five main areas: elective services, trauma services, allied health services, patient access and practice demographics. RESULTS: 98.7% of general practitioners surveyed stated they either agree or strongly agree that there is a significant difference in terms of access between public and private services. The average waiting time for an elective orthopaedic outpatient clinic is more than 1 year as per 92.3% of GPs surveyed with 89.7% of GPs stating that the average waiting time for an elective private outpatient appointment being between 0 and 3 months. Over three quarters of GPs surveyed either disagree or strongly disagree that there is adequate access to physiotherapy and occupational therapy services in the community with nearly 80% and 93.6% stating they have no physiotherapist or occupational therapist respectively attached to their practice. CONCLUSION: MSK disorders are a significant burden on the Irish health service and inadequate investment in general practice, allied health practitioner-led facilities and orthopaedic services remains a serious challenge that requires considerable attention to insure adequate patient care, safety and best practice.

Financial impact of inaccurate Adverse Event recording post Hip Fracture surgery: Addendum to 'Adverse event recording post hip fracture surgery'.

INTRODUCTION: A study in 2011 by (Doody et al. Ir Med J 106(10):300-302, 2013) looked at comparing inpatient adverse events recorded prospectively at the point of care, with adverse events recorded by the national Hospital In-Patient Enquiry (HIPE) System. METHODS: In the study, a single-centre University Hospital in Ireland treating acute hip fractures in an orthopaedic unit recorded 39 patients over a 2-month (August-September 2011) period, with 55 adverse events recorded prospectively in contrast to the HIPE record of 13 (23.6%) adverse events. With the recent change in the Irish hospital funding model from block grant to an 'activity-based funding' on the basis of case load and case complexity, the hospital financial allocation is dependent on accurate case complexity coding. A retrospective assessment of the financial implications of the two methods of adverse incident recording was carried out. RESULTS: A total of €39,899 in 'missed funding' for 2 months was calculated when the ward-based, prospectively collected data was compared to the national HIPE data. Accurate data collection is paramount in facilitating activity-based funding, to improve patient care and ensure the appropriate allocation of resources.

Obtaining local bone graft for Evans calcaneal osteotomy in pes planovalgus deformity correction.

Lateral column lengthening osteotomy is very useful surgical technique in treating stage II of pes planovalgus deformity of the foot. Either autograft from the iliac crest or allograft can be used for this purpose. In our technique we describe a novel method of obtaining bone graft locally from the calcaneus and therefore avoiding complications and morbidity associated with iliac crest graft.

Recording Adverse Events Following Joint Arthroplasty: Financial Implications and Validation of an Adverse Event Assessment Form.

BACKGROUND: In Ireland, funding of joint arthroplasty procedures has moved to a pay-by-results national tariff system. Typically, adverse clinical events are recorded via retrospective chart-abstraction methods by administrative staff. Missed or undocumented events not only affect the quality of patient care but also may unrealistically skew budgetary decisions that impact fiscal viability of the service. Accurate recording confers clinical benefits and financial transparency. The aim of this study was to compare a prospectively implemented adverse events form with the current national retrospective chart-abstraction method in terms of pay-by-results financial implications. METHODS: An adverse events form adapted from a similar validated model was used to prospectively record complications in 51 patients undergoing total hip or knee arthroplasties. Results were compared with the same cohort using an existing data abstraction method. Both data sets were coded in accordance with current standards for case funding. RESULTS: Overall, 114 events were recorded during the study through prospective charting of adverse events, compared with 15 events documented by customary method (a significant discrepancy). Wound drainage (15.8%) was the most common complication, followed by anemia (7.9%), lower respiratory tract infections (7.9%), and cardiac events (7%). A total of €61,956 ($67,778) in missed funding was calculated as a result. CONCLUSION: This pilot study demonstrates the ability to improve capture of adverse events through use of a well-designed assessment form. Proper perioperative data handling is a critical aspect of financial subsidies, enabling optimal allocation of funds.
