Initial experience of TAS-102 chemotherapy in Australian patients with Chemo-refractory metastatic colorectal cancer.

For patients with refractory metastatic colorectal cancer (mCRC) treatment with Trifluridine/Tipiracil, also known as TAS-102, improves overall survival. This study aims to investigate the efficacy and safety of TAS-102 in a real-world population from Victoria, Australia. A retrospective analysis of prospectively collected data from the Treatment of Recurrent and Advanced Colorectal Cancer (TRACC) registry was undertaken. The characteristics and outcomes of patients receiving TAS-102 were assessed and compared to those enrolled in the registration study (RECOURSE). Across 13 sites, 107 patients were treated with TAS-102. The median age was 60 years (range: 31-83), compared to 63 for RECOURSE. Comparing registry TAS-102-treated and RECOURSE patients, 75% vs 100% were ECOG performance status 0-1, 74% vs 79% had initiated treatment more than 18 months from diagnosis of metastatic disease and 36% vs 49% were RAS wild-type. Median time on treatment was 10.4 weeks (range: 1.7-32). Median progression-free survival (PFS) was 3.3 months compared to 2 months in RECOURSE, while median overall survival was the same at 7.1 months. Two patients (2.3%) had febrile neutropenia and there were no treatment-related deaths, where TAS-102 dose at treatment initiation was at clinician discretion.TRACC registry patients treated with TAS-102 were younger than those from the RECOURSE trial, with similar overall survival observed. Less strict application of RECIST criteria and less frequent imaging may have contributed to an apparently longer PFS.

Consensus on core phenomena and statements describing Basic Body Awareness Therapy within the movement awareness domain in physiotherapy.

Physiotherapists are facing complex health challenges in the treatment of persons suffering from long-lasting musculoskeletal disorders and mental health problems. Basic Body Awareness Therapy (BBAT) is a physiotherapy approach within the movement awareness domain developed to bridge physical, mental, and relational health challenges. The purpose of this study was to reach a consensus on core phenomena and statements describing BBAT. A consensus-building process was conducted using the nominal group technique (NGT). Twenty-one BBAT experts from 10 European countries participated in a concentrated weekend workshop of 20 hours. All participants signed informed consent. Participants reached a consensus on 138 core phenomena, clustered in three overarching categories: clinical core, historical roots, and research and evaluation phenomena. Of the 106 clinical core phenomena, the participants agreed on three categories of phenomena: movement quality, movement awareness practice, and movement awareness therapy and pedagogy. Furthermore, the participants reached 100 percent consensus on 16 of 30 statements describing BBAT. This study provides a consensus on core phenomena and statements describing BBAT. The data reveal phenomena implemented when promoting movement quality through movement awareness. Data provide clarity in some aspects of the vocabulary as fundamental theory. Further reearch will be developed.

Has aerobic exercise effect on pain perception in persons with migraine and coexisting tension-type headache and neck pain? A randomized, controlled, clinical trial.

BACKGROUND: A large subset of persons with migraine suffers from coexisting tension-type headache and neck pain which may adversely affect the prognosis of migraine. Aerobic exercise has been shown to decrease migraine burden in these persons. Therefore, the aim of this study was to investigate whether the effect of aerobic exercise in persons with migraine and coexisting tension-type headache and neck pain can be explained by changes in pain perception. METHOD: Seventy consecutively recruited persons with migraine and coexisting tension-type headache and neck pain were randomized into exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 min, three times/week for 3 months. Controls continued their usual daily activities. Pericranial tenderness, pain thresholds, supra-thresholds and temporal summation were assessed at baseline, after treatment and at follow-up (6 months from baseline). RESULTS: Fifty-two persons with migraine and coexisting tension-type headache and neck pain completed the study. Aerobic exercise did not induce consistent changes in nociceptive pathways measured by pericranial tenderness, pressure pain thresholds and sensitivity to electrical stimulation. CONCLUSION: The effect of aerobic exercise cannot be explained by measurable effects on the pain modulation system. Thus, the positive effect on migraine burden may rather be explained by positive alteration of avoidance behaviour. Aerobic exercise can be recommended as a safe and inexpensive migraine treatment strategy. SIGNIFICANCE: This study adds further knowledge about the positive effect of aerobic exercise for persons with migraine and coexisting tension-type headache and neck pain. This effect cannot be measured by changes in pain modulation, but may rather be explained by positive alteration of avoidance behaviour.

Effects of a self-guided, web-based activity programme for patients with persistent musculoskeletal pain in primary healthcare: A randomized controlled trial.

BACKGROUND: Web-based interventions for pain management are increasingly used with possible benefits, but never used in addition to multimodal rehabilitation (MMR). MMR is recommended treatment for persistent pain in Sweden. The aim was to evaluate the effects of a self-guided, web-based programme added to MMR for work ability, pain, disability and health-related quality of life. METHODS: We included 99 participants with persistent musculoskeletal pain in a randomized study with two intervention arms: (1) MMR and web-based intervention, and (2) MMR. Data was collected at baseline, 4 and 12 months. Outcome measures were work ability, working percentage, average pain intensity, pain-related disability, and health-related quality of life. RESULTS: There were no significant effects of adding the web-based intervention to MMR regarding any of the outcome variables. CONCLUSIONS: This trial provides no support for adding a self-guided, web-based activity programme to MMR for patients with persistent musculoskeletal pain. SIGNIFICANCE: The comprehensive self-guided, web-based programme for activity, Web-BCPA, added to multimodal treatment in primary health care had no effect on work ability, pain, disability or health-related quality of life. Future web-based interventions should be tailored to patients' individual needs and expectations.

The effect of pelvic floor muscle training on sexual function in men with lower urinary tract symptoms after stroke.

BACKGROUND: Erectile dysfunction and lower urinary tract symptoms (LUTS) are common sequelae in men after stroke. OBJECTIVE: The objective of this study was to evaluate the effect of pelvic floor muscle training (PFMT) on measured erectile function as an indicator of sexuality in men with LUTS after stroke. METHOD: A sample of 516 men with stroke was invited to participate in this single-blinded, randomized controlled trial according to in- and exclusion criteria. This resulted in 31 participants who were randomized to either a Treatment Group (n = 16) or a Control Group (n = 15). The intervention included 12♣weeks of PFMT. The effect was measured on the International Index of Erectile Function (IIEF-5) questionnaire. RESULTS: Thirty participants (median age: 68 years; interquartile range: 60-74 years) completed the study, 15 in each group. The results of the IIEF-5 sum score showed a significant improvement (P < 0.04) from pre-test to post-test in the Treatment Group, but not in the Control Group. Within pre-test and 6-month follow-up, the median sum score decreased in both groups, worsened in the Control Group [Treatment Group, 3 (17%) versus Control Group, 5 (31%)]. There were differences between the groups at post-test and at follow-up, but they were not statistically significant. CONCLUSION: The results showed that, as measured by erectile function in men with LUTS after stroke, PFMT may have short-term and long-term effect, although no statistically significant effect was demonstrated between the groups.

Personal factors in systemic sclerosis and their coverage by patient-reported outcome measures. A multicentre European qualitative study and literature review.

BACKGROUND: Systemic sclerosis (SSc) is an autoimmune disease where thickening of the skin can lead to reduced body function and limitations in activities. Severe forms can also affect and seriously damage inner organs. Patient-centred rehabilitation emphasises considerations of patients' background, experience and behavior which highlights the need to know if patient-reported outcome measures (PROMs) include such personal factors. AIM: To identify and describe personal factors in the experiences of functioning and health of persons with SSc and to examine if and to what extent PROMs in SSc research cover these factors. DESIGN: Data from a qualitative study with focus group interviews were analysed. PROMs in SSc research were identified in a literature review between 2008-2013. SETTING: Participants were recruited from outpatient clinics at rheumatology department. POPULATION: Sixty-three patients with SSc from four European countries participated. METHODS: Data from interviews were analysed using a structure of personal factors developed by Geyh et al. Identified PROMs were analysed and linked to main concepts, related to the personal factors, found in the interview data. RESULTS: Nineteen main concepts were related to the area "patterns of experience and behaviour" in the personal factor structure, 16 to "thoughts and beliefs", nine to "feelings", one to "motives" and one to "personal history and biography", respectively. Among the 35 PROMs identified, 15 did not cover any of the identified concepts. Concepts within the area "feelings" were mostly covered by the PROMs. Five of the PROMs covered "patterns of experience and behaviour", while "motives" and "personal history and biography" were not covered at all. Four of the identified PROMs covered concepts within the areas "feelings", "thoughts and beliefs" and "patterns of experience and behaviour" in the same instrument. The Illness Cognition Questionnaire and Illness Behaviour Questionnaire were such PROMs. CONCLUSION: Patterns of experience and behaviour had the highest number of concepts related to personal factors, but few of the PROMs in SSc research covered these factors. Only a few PROMs covered several personal factors areas in the same instrument. CLINICAL REHABILITATION IMPACT: The results would be of value when developing core sets for outcome measurements in SSc.

Dietary folate and related micronutrients, folate-metabolising genes, and ovarian cancer survival.

OBJECTIVE: Folate is essential for DNA synthesis and methylation and is implicated in tumour progression. Few studies have examined its role in ovarian cancer survival. Our objective was to determine relationships between intake of folate, related one-carbon nutrients, single nucleotide polymorphisms (SNPs) in folate-metabolising genes and survival following ovarian cancer diagnosis. METHODS: This analysis included 1270 women with invasive epithelial ovarian cancer diagnosed in 2002-2006. Pre-diagnostic and some post-diagnostic lifestyle, dietary, and sociodemographic information was collected via self-administered questionnaires. DNA samples were genotyped for SNPs in methylenetetrahydrofolate reductase (MTHFR), methionine synthase (MTR) and methionine synthase reductase (MTRR) genes. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox regression. RESULTS: Multivariate analyses did not identify associations between higher pre-diagnostic intake of folate, folic acid, vitamins B2, B6, and B12, methionine, betaine or choline and survival overall. In stratified analyses, higher folic acid and folate intake was associated with significantly worse survival among women with mucinous tumours (HRs per 100 µg 1.30 and 1.43, respectively) and smokers (HRs per 100 µg 1.23 and 1.16 respectively). There was also a suggestion that higher supplemental folic acid use post-diagnosis was associated with worse survival (HR per 100 µg 1.03, 95%CI 1.00-1.05). MTHFR SNP rs2066470 was significantly associated with survival (per allele HR 0.81, 95%CI 0.67-0.98). CONCLUSIONS: Our data provide little evidence that folate intake affects ovarian cancer survival. However, combined effects with smoking, and findings within the mucinous subtype and for post-diagnosis folic acid, warrant further investigation.

Perceptions of health and risk management among home care workers in Sweden.

BACKGROUND: Municipal home care workers provide high-quality services to an increasing proportion of elderly people living in private homes. The work environments and working conditions of these workers vary to a great extent, implying rapid priority-making among both employers and employees to ensure that the work can be performed in a safe way. OBJECTIVES: This study aims to examine home care workers' perceptions of health, risks, working conditions, and risk management within their organization. METHOD: The study was based on cross-sectional data collected from home care service staff in a municipality in the north of Sweden. Nursing assistants and care aides (n = 133) replied to a self-administered questionnaire. Descriptive statistics and between-group differences were analysed. RESULTS: Home care work was perceived to require high levels of professional skill and ingenuity, a good psychosocial work situation, but required a high physical workload. The general health, the capacity and self-efficacy of the staff in relation to work were good. Difficulty in performing risk assessments and following safety regulations due to lack of time, equipment, and information were identified. CONCLUSION: There is a need to increase participation in risk assessments among the staff, improve management support, structures, and cooperation with other divisions of the social services and the medical care organizations.

Uncertainty and opportunities in patients with established systemic lupus erythematosus: a qualitative study.

UNLABELLED: Systemic lupus erythematosus (SLE) is a chronic disease which can affect any organ, and the impact of the condition will affect each person differently. There are few qualitative studies including the experiences of both women and men with a diagnosis of SLE corresponding to the American College of Rheumatology (ACR) criteria where both negative and positive impacts of the disease have been presented. PURPOSE: The aim was to describe how patients with established SLE experience their illness in everyday life, including both negative and positive aspects. METHOD: Four focus group interviews were conducted with 16 women and three men with SLE according to ACR criteria, with varied disease activity and no or little organ damage. The interviews were tape recorded, transcribed verbatim and analysed using qualitative content analysis. RESULTS: Two themes emerged: multifaceted uncertainty contained the categories 'an unreliable body', 'obtrusive pain and incomprehensible fatigue', 'mood changes and worries', 'reliance on medication and health care'; Focus on health and opportunities included 'learning process implying personal strength', 'limitations and possibilities in activities and work', 'a challenge to explain and receive support' and 'living an ordinary life incorporating meaningful occupations'. CONCLUSIONS: While we expected to find a mainly negative impact, positive aspects were also described. Our findings were complex and showed that patients with established SLE can experience both uncertainty and opportunities. This highlights the importance for healthcare professionals of gaining a better understanding of patients' uncertainty, to enable them to support patients, allowing them to focus on health and opportunities. Measurement instruments that capture different aspects of uncertainty and opportunities needs to be developed.

Bandwidth tuning triggers interplay of charge order and superconductivity in two-dimensional organic materials.

We observe charge-order fluctuations in the quasi-two-dimensional organic superconductor ß''-(BEDT-TTF)2SF5CH2CF2SO3, both by means of vibrational spectroscopy, locally probing the fluctuating charge order, and by investigating the in-plane dynamical response by infrared reflectance spectroscopy. The decrease of the effective electronic interaction in an isostructural metal suppresses both charge-order fluctuations and superconductivity, pointing to their interplay. We compare the results of our experiments with calculations on the extended Hubbard model.

Reliability and validity of the Fatigue Severity Scale in Swedish for patients with systemic lupus erythematosus.

OBJECTIVE: The aim was to translate, test, and describe aspects of reliability and validity of the Fatigue Severity Scale (FSS) in Swedish (FSS-Swe) in patients with systemic lupus erythematosus (SLE). METHODS: Patients with stable SLE, low or moderate disease activity, and low organ damage were included. Forward and back translations of the FSS were performed. Construct validity was tested with 32 women using a first Swedish translation. Feasibility, ceiling and floor effects, internal consistency, test-retest reliability, and content validity were tested on a slightly modified final version of the FSS-Swe in a non-selected group of patients (n = 23). RESULTS: There were correlations (p< or =0.05) between the FSS-Swe and overall disease activity according to the Systemic Lupus Activity Measure (SLAM) (r(s) = 0.48) and the SLAM Visual Analogue Scale (SLAM-VAS) (r(s) = 0.46); between the FSS-Swe and eight subscales of the Swedish 36-Item Medical Outcomes Study Short-Form Health Survey (SF-36) (r(s) = -0.41 to -0.65) and between the FSS-Swe and age (r(s) = -0.35). All patients answered all FSS-Swe questions at both test and retest. There was one ceiling effect in one question on one occasion. The Kolmogorov-Smirnov test indicated normal distribution. Cronbach's alpha was 0.94 and corrected item-to-total correlation exceeded 0.3. There were no significant systematic test-retest differences, and the median-weighted kappa coefficient was 0.75. Twenty patients understood the questions in FSS-Swe, 18 considered they were relevant, reflected their fatigue, and that none should be excluded. Five items were suggested to be included. CONCLUSIONS: The FSS-Swe supports construct validity, is feasible, has no important ceiling or floor effects, has satisfactory internal consistency, substantial test-retest reliability, and satisfactory content validity in the SLE patients studied. However, its sensitivity to change needs to be tested.

The Lighthouse Alarm and Locator trial - a pilot study.

An important factor for health is the possibility to be active and mobile. To make this possible various kinds of support are needed. Integrating geographical information systems technology and user experiences is important in the development of more user-friendly positioning devices. The Lighthouse Alarm and Locator trial aimed to test a new mobile alarm system with additional functionality such as positioning and monitoring of vital signs which can be used regardless of location (in hospital, at home). The system was tested by elderly persons from a pensioner organisation and home care personnel answered up on the alarms. After the tests qualitative interviews were performed with the two groups. The results showed that their experiences of the new mobile alarm system could be described in three main categories: to be supervised, to feel safe and to be mobile. These categories formed a theme: Positioning - an ethical dilemma. The clients' mobility was perceived to increase. The personnel did not think that positioning was ethical but the clients (elderly) did.

Is there a long-lasting effect of pelvic floor muscle training in women with urinary incontinence after ischemic stroke? A 6-month follow-up study.

The aim of this study was to evaluate the long-lasting effect of pelvic floor muscle training (PFMT) in women with urinary incontinence after stroke measured by quality of life parameters. Twenty-four (24/24) women with urinary incontinence after stroke, who had completed a prospective, randomised controlled and single-blinded trial evaluating the effect of 12 weeks PFMT, were included in this follow-up study. The follow-up assessments were done by telephone interview 6 months after the intervention. The effect was evaluated by The Short Form 36 (SF-36) Health Survey Questionnaire and Incontinence Impact Questionnaire (IIQ). Twenty-four subjects completed the study. In the treatment group, the SF-36 showed a trend to a long-lasting effect in one of the eight domains and the IIQ showed a tendency to decreased impact of UI in two sub-scales compared to the control group. Our data indicated that PFMT may have a long-lasting effect measured by quality of life parameters.

Development and reliability of the Motivation for Change Questionnaire.

PURPOSE: The purpose of this study was to describe the development of the Motivation for Change Questionnaire (MCQ) and to test its intra-patient reliability on musculoskeletal pain patients in interdisciplinary rehabilitation as a basis for use in rehabilitation planning. METHOD: The MCQ questionnaire was developed from a literature search in the Medline, Cinahl and Psychlit databases concerning motivating factors for change in the life and work situation. Questions covering these factors were developed (item generation). Factor analysis of the questions implied a reduction of the number of questions (item reduction). Inter-item correlation was assessed on the baseline administration of the questionnaire by calculating Cronbach's alpha. When testing the structure of the scales, it was shown that the MCQ questionnaire could be described in two scales, one scale relating to motivation for change in the life situation and the other focusing on motivation for change in the work situation and in total 49 questions. RESULTS: The test -- retest reliability was calculated using the intra-class correlation coefficient (ICC) and 95% confidence intervals were calculated. One question was excluded due to the threshold limit of > 0.5. Seven scales relating to the life situation were accepted by the analysis: social support, mastery in life, challenges in life, control in life, values, self-efficacy and self-confidence. Six scales relating to the work situation were also accepted: co-worker support, supervisory support, challenges in work, job control, interaction and job-satisfaction. CONCLUSIONS: The MCQ questionnaire with 48 questions is reliable for use on musculoskeletal pain patients in interdisciplinary rehabilitation. It can be used to identify each individual's motivating factors for change in life and work situation as a basis for motivational work within rehabilitation and/or to measure within-subject changes in motivation over time. The validity and the responsiveness of the MCQ, need to be studied.

Coping after trans-femoral amputation due to trauma or tumour--a phenomenological approach.

PURPOSE: To describe, by use of a phenomenological approach, how relatively young trans-femoral amputees experienced their amputation and their coping strategies in the acute phase and over time. METHOD: Eleven trans-femoral amputees, median age 33.5 years, were interviewed. The amputation was caused by tumour, motorcycle accidents or work-related traumas. Amputation was made in median 7.5 years before the interview. The informants were community dwelling and managed well indoors. One had a half disablement pension and all the others were working or studying full time. The interviews were tape-recorded and transcribed verbatim. RESULTS: Two themes emerged. In the first theme 'Experiences of the amputation' denial and avoidance were the coping strategies mainly used. In the second theme 'Coping strategies to relate to a new norm' the informants used downward comparison, positive comparison and repression. Only one informant indicated a full acceptance of his situation. CONCLUSION: Relatively young, trans-femoral amputees within this sample, have not reached the acceptance level, though a long time has passed since the amputation. They might have benefited from professional support and guidance during the rehabilitation process in order to improve coping strategies to relate to a new norm.

Self-assembled organic monolayers terminated in perfluoroalkyl pentafluoro-lambda(6)-sulfanyl (-SF5) chemistry on gold.

Recently synthesized (Winter, R.; Nixon, P. G.; Gard, G. L.; Radford, D. H.; Holcomb, N. R.; Grainger, D. W. J. Fluorine Chem. 2001, 107, 23-30) SF5-terminated perfluoroalkyl thiols (SF5(CF2)nCH2CH2SH, where n = 2, 4, and 6) and a symmetric SF5-terminated dialkyl disulfide ([SF5-CH=CH-(CH2)8-S-]2) were assembled as thin films chemisorbed onto gold surfaces. The adsorbed monolayer films of these SF5-containing molecules on polycrystalline gold were compared using ellipsometry, contact angle, X-ray photoelectron spectroscopy (XPS), time-of-flight secondary ion mass spectrometry (ToF-SIMS), and infrared spectroscopy (FTIR) surface analytical methods. The resulting SF5-dialkyl disulfide monolayer film shows moderate angle dependence in depth-dependent XPS analysis, suggesting a preferentially oriented film. The SF5-terminated perfluoroalkyl thiols exhibit angular-dependent XPS compositional variance depending on perfluoroalkyl chain length, consistent with improved film assembly (increasingly hydrophobic, fewer defects, and more vertical chain orientation increasing film thickness) with increasing chain length. Tof-SIMS measurements indicate that both full parent ions for these film-forming molecules and the unique SF5 terminal group are readily detectable from the thin films without substantial contamination from other adsorbates.

Overview of bluetongue disease, viruses, vectors, surveillance and unique features: the Indian sub-continent and adjacent regions.

The occurrence of bluetongue (BT) disease in India was initially confined to exotic breeds of sheep and subsequently became endemic in native breeds. BT virus (BTV) antibodies are common in cattle, buffaloes and goats although clinical disease has not been reported. Exotic breeds of sheep and their cross-breeds are more susceptible to disease than native breeds. Overall, morbidity, mortality and case fatality rates of 9.3%, 2.7% and 28.8%, respectively, have been reported in rural flocks; these rates are higher than in organised farms. The disease is mostly cyclical in occurrence. Outbreaks usually occur between June and December during the monsoon period when livestock biting midges greatly increase. BTVs have been isolated from native sheep, and sentinel herds have been used to demonstrate virus activity. A total of 21 serotypes of BTV have now been reported in the country. Major impediments to control the disease include the presence of multiple virus serotypes, the broad vertebrate host range of the virus and a lack of detailed knowledge of vectors. Inactivated vaccines prepared from local isolates are currently under field trials. BTV occurs in regions adjacent to India. An antibody prevalence of 48.4% has been reported in Pakistan with serotypes 3, 9, 15, 16 and 18 identified. BTV antibody, but not disease, has been reported in Bangladesh and Sri Lanka.

Towards a learning organization: the introduction of a client-centered team-based organization in administrative surveying work.

Within administrative surveying work in Sweden, a transition to a client-centered team-based organization was made during 1998. The aim of this study was to describe the employees' perceptions and expectations of job and organizational practices when working as a generalist in a client-centered team-based organization; job and organizational practices and well-being and effectiveness measures were examined when introducing a team-based organization. Interventions such as courses in how to cope with the role of a generalist, how to increase service to clients, education in technology, law and economics, as well as computer information support, were ongoing at the time of the study. The Team Work Profile and QPS Nordic questionnaires were used. All the surveyors in five regions in Sweden participated, in total 640 surveyors. The transition to a client-centered team-based organization was expected to improve job control and job content but at the same time lead to impairments in job climate and group cohesion. Distress was associated with negative future expectations of the organization. High job control and group cohesion were the central contributors towards growth in personal competence and social effectiveness of teamwork. Both internal and external client-related activities of team and organization were in focus during the transition.

The expected economic impact of selected exotic diseases on the pig industry of Australia.

The authors assess the expected economic impact of three exotic diseases on the pig industry of Australia. An integrated epidemiological/economic approach was used to assess the effects of classical swine fever, Nipah virus and porcine reproductive and respiratory syndrome. Scenarios involving either an epidemic event, in which the outbreaks were confined to selected regions and were eradicated, or an endemic situation, in which the diseases became established in Australia, were studied. Based only on loss of sales and disposal costs, epidemics resulted in regional losses in income of the order of AUS$10 million-AUS$30 million (16%-37%) depending on disease and region. If any of these diseases became established, opportunity losses in gross national pig income of 5%-11% per year would occur, with classical swine fever the most serious of the three diseases. Establishment of any of the diseases would lead to rapid structural change in the pig industry, with concomitant social and economic dislocation in regional Australia.

Chemical insights from high-resolution X-ray photoelectron spectroscopy and ab initio theory: propyne, trifluoropropyne, and ethynylsulfur pentafluoride.

High-resolution carbon 1s photoelectron spectroscopy of propyne (HC triple bond CCH3) shows a spectrum in which the contributions from the three chemically inequivalent carbons are clearly resolved and marked by distinct vibrational structure. This structure is well accounted for by ab initio theory. For 3,3,3-trifluoropropyne (HC triple bond CCF3) and ethynylsulfur pentafluoride (HC triple bond CSF5), the ethynyl carbons show only a broad structure and have energies that differ only slightly from one another. The core-ionization energies can be qualitatively understood in terms of conventional resonance structures; the vibrational broadening for the fluorinated compounds can be understood in terms of the effects of the electronegative fluorines on the charge distribution. Combining the experimental results with gas-phase acidities and with ab initio calculations provides insights into the effects of initial-state charge distribution and final-state charge redistribution on ionization energies and acidities. In particular, these considerations make it possible to understand the apparent paradox that SF5 and CF3 have much larger electronegativity effects on acidity than they have on carbon 1s ionization energies.
