Abstract
IMPORTANCE Assisted living (AL) is the largest provider of residential long-term care in the US, and the morbidity of AL residents has been rising. However, AL is not a health care setting, and concern has been growing about residents' medical and mental health needs. No guidance exists to inform this care. OBJECTIVE To identify consensus recommendations for medical and mental health care in AL and determine whether they are pragmatic. EVIDENCE REVIEW A Delphi consensus statement study was conducted in 2021; as a separate effort, the extent to which the recommendations are reflected in practice was examined in data obtained from 2016 to 2021 (prepandemic). In the separate effort, data were from a 7-state study (Arkansas, Louisiana, New Jersey, New York, Oklahoma, Pennsylvania, Texas). The 19 Delphi panelists constituted nationally recognized experts in medical, nursing, and mental health needs of and care for older adults; dementia care; and AL and long-term care management, advocacy, regulation, and education. One invitee was unavailable and nominated an alternate. The primary outcome was identification of recommended practices based on consensus ratings of importance. Panelists rated 183 items regarding importance to care quality and feasibility. FINDINGS Consensus identified 43 recommendations in the areas of staff and staff training, nursing and related services, resident assessment and care planning, policies and practices, and medical and mental health clinicians and care. To determine the pragmatism of the recommendations, their prevalence was examined in the 7-state study and found that most were in practice. The items reflected the tenets of AL, the role of AL in providing dementia care, the need for pragmatism due to the diversity of AL, and workforce needs. CONCLUSIONS AND RELEVANCE In this consensus statement, 43 recommendations important to medical and mental health care in AL were delineated that are highly pragmatic as a guide for practice and policy.

Colonoscopy skills improvement training improves patient comfort during colonoscopy. Surg Endosc 2022; 36:4588-4592. [PMID: 34622297 DOI: 10.1007/s00464-021-08753-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Accepted: 09/27/2021] [Indexed: 01/29/2023]
Abstract
INTRODUCTION We aimed to assess the effect of Colonoscopy Skills Improvement (CSI) training on patient comfort and sedation-related complications during colonoscopy. METHODS This retrospective cohort study was performed on 19 endoscopists practicing in a Canadian tertiary care center who completed CSI training between October 2014 and May 2016. Data from 50 procedures immediately prior to, immediately after, and eight months following CSI training were included for each endoscopist. The primary outcome variable was intraprocedural comfort, and secondary outcomes included intraprocedural hypotension and hypoxia. Data were extracted from an electronic medical record and analyzed using SPSS version 20.0. Univariate analysis and stepwise multivariable logistic regression were performed to determine if there was an association between patient comfort and CSI training. Predictors of these outcomes including patient age, gender, sedation use and dosing, procedure completion, quality of bowel preparation, endoscopist experience, and specialty were included in the analysis. RESULTS 2533 colonoscopies were included in the study. The mean dose of sedatives was reduced immediately following CSI training and at 8 months for both Fentanyl (75.4 mcg v. 67.8 mcg v. 65.9 mcg, p < 0.001) and Midazolam (2.57 mg v. 2.27 mg v. 2.19 mg, p < 0.001). The percentage of patients deemed to have a comfortable exam improved following endoscopist participation in CSI training and remained improved at 8 months (55.1% v. 70.2% v. 69.8%, p < 0.001). No significant change in rates of intraprocedural hypoxia or hypotension were noted following CSI training. CONCLUSION CSI training is associated with improved patient comfort and reduced sedation requirements during colonoscopy.

Pragmatic Trials in Long-Term Care: Implementation and Dissemination Challenges and Opportunities. J Am Geriatr Soc 2022; 70:709-717. [PMID: 35195281 PMCID: PMC8944211 DOI: 10.1111/jgs.17698] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Accepted: 02/01/2022] [Indexed: 11/28/2022]
Abstract
Randomized controlled trials are considered the most rigorous research design in efficacy and effectiveness research; however, such trials present numerous challenges that limit their applicability in real-world settings. As a consequence, pragmatic trials are increasingly viewed as a research design that overcomes some of these barriers with the potential to produce findings that are more reproducible. Although pragmatic methodology in long-term care is receiving increasing attention as an approach to improve successful dissemination and implementation, pragmatic trials present complexities of their own. To address these complexities and related issues, experts with experience conducting pragmatic trials, developing nursing home policy, participating in advocacy efforts, and providing clinical care in long-term care settings participated in a virtual consensus conference funded by the National Institute on Aging in Spring 2021. Participants identified 4 cross-cutting principles key to dissemination and implementation of pragmatic trial interventions: (1) stakeholder engagement, (2) diversity and inclusion, (3) organizational strain and readiness, and (4) learn from adaptations. Participants emphasized that implementation processes must be grounded in the perspectives of the people who will ultimately be responsible for implementing the intervention once it is proven to be effective. In addition, messaging must speak to long-term care staff and all others who have a stake in its outcomes. Although our understanding of dissemination and implementation strategies remains underdeveloped, this article is designed to guide long-term care researchers and community providers who are increasingly aware of the need for pragmatism in disseminating and implementing evidence-based care interventions.

Abstract
Abstract
Introduction
Telemedicine is increasingly an option for delivery of healthcare services, but its efficacy and acceptability for delivering CBT for insomnia has not been adequately tested. In a randomized controlled non-inferiority trial, we compared face-to-face and telemedicine delivery (via the AASM SleepTM platform) of CBT for insomnia for improving sleep and daytime functioning at post-treatment and 12-week follow-up.
Methods
Sixty-five adults with chronic insomnia (46 women, mean age 47.2 ± 16.3 years) were recruited primarily from insomnia clinics and screened for disqualifying sleep, medical, and mental health disorders. Eligible participants were randomized to 6 sessions of CBT for insomnia delivered face-to-face (n=32) or via AASM SleepTM (n=33). Participants completed self-report measures of insomnia (Insomnia Severity Index, ISI) and daytime functioning (fatigue, depression, anxiety, and overall functioning) at pre-treatment, post-treatment, and 12-week follow-up. The ISI was the primary non-inferiority outcome.
Results
Telemedicine was non-inferior to face-to-face delivery of CBT for insomnia, based on a non-inferiority margin of 4 points on the ISI (β = -0.07, 95% CI -2.28 to 2.14). Compared to pre-treatment, ISI scores improved significantly at post-treatment (β = -9.02, 95% CI -10.56 to -7.47) and at 12-week follow-up (β = -9.34, 95% CI -10.89 to -7.79). Similarly, daytime functioning measures improved from pre- to post-treatment, with sustained improvements at 12-week follow-up. Scores on the fatigue scale were lower in the telemedicine group at both post-treatment (F=4.64, df=1,119, p<.03) and follow-up (F=5.79, df=1,119, p<.02).
Conclusion
Insomnia and daytime functioning improve similarly whether CBT for insomnia is delivered via telemedicine or face-to-face. Telemedicine delivery of CBT for insomnia should be implemented more systematically to improve access to this evidence-based treatment.

Abstract
Abstract
Introduction
CBT for insomnia (CBTI) is effective but a barrier to its widespread use is the lack of evidence-based delivery modalities other than face-to-face. The perception and acceptability of telemedicine for the delivery of CBTI is unknown. We conducted a randomized controlled non-inferiority trial comparing face-to-face (F2F) and telemedicine (via AASM SleepTM) delivery of CBTI. We compared measures of patient satisfaction with treatment and the perception of the therapist’s warmth and skills between F2F and SleepTM.
Methods
Adults with insomnia were recruited from insomnia clinics and the community and screened for sleep, medical, and mental health disorders. Eligible participants were randomized to receive CBTI either via AASM SleepTM or F2F in 6 weekly sessions of 45-60 minutes each. Participants completed the Client Satisfaction Questionnaire (CSQ-8) and The Therapy Evaluation Questionnaire (TEQ) after completing treatment. The CSQ-8 score ranges from 8-32 with high scores indicating greater satisfaction. We also analyzed the two items on the TEQ that assess participants’ perception of therapist’s warmth and skills. Item scores ranged from 1-7, with higher scores indicating greater warmth and skills.
Results
Sixty-five adults with chronic insomnia were recruited primarily from insomnia clinics. Sixty-two participants (41 women, mean age 48.9 ± 15.4 years) completed all 6 sessions of CBTI via F2F (n=32) or via AASM SleepTM (n=30). Independent samples t-tests revealed no significant differences between conditions on patient satisfaction (SleepTM, 28.5 +/-4.2 vs F2F 29.9 +/-2.4, t(-1.5), p=.14), therapist warmth (SleepTM, 6.0 ±1.1 vs F2F, 6.4±0.95, t(-1.4), p=.16), or therapist skills (Sleep TM 6.4 ±1.0 vs F2F, 6.7±0.59, t(-1.5), p=.15).
Conclusion
Our findings suggest no differences in patient satisfaction, perception of therapist’s warmth, or confidence in therapist’s skills between telemedicine (via the AASM SleepTM) and F2F delivery of CBTI. Telemedicine-delivered CBTI should be implemented more widely.

Abstract
We describe an experimental setup for making precision measurements of relative β-decay rates of (22)Na, (36)Cl, (54)Mn, (60)Co, (90)Sr, (133)Ba, (137)Cs, (152)Eu, and (154)Eu. The radioactive samples are mounted in two automated sample changers that sequentially position the samples with high spatial precision in front of sets of detectors. The set of detectors for one sample changer consists of four Geiger-Müller (GM) tubes and the other set of detectors consists of two NaI scintillators. The statistical uncertainty in the count rate is few times 0.01% per day for the GM detectors and about 0.01% per hour on the NaI detectors. The sample changers, detectors, and associated electronics are housed in a sealed chamber held at constant absolute pressure, humidity, and temperature to isolate the experiment from environmental variations. The apparatus is designed to accumulate statistics over many years in a regulated environment to test recent claims of small annual variations in the decay rates. We demonstrate that absent this environmental regulation, uncontrolled natural atmospheric pressure variations at our location would imprint an annual signal of 0.1% on the Geiger-Müller count rate. However, neither natural pressure variations nor plausible indoor room temperature variations cause a discernible influence on our NaI scintillator detector count rate.

A vacuolar-H(+) -pyrophosphatase (TgVP1) is required for microneme secretion, host cell invasion, and extracellular survival of Toxoplasma gondii. Mol Microbiol 2014; 93:698-712.

Abstract
The vacuolar proton pyrophosphatase (H(+) -PPase) of Toxoplasma gondii (TgVP1), a membrane proton pump, localizes to acidocalcisomes and a novel lysosome-like compartment termed plant-like vacuole (PLV) or vacuolar compartment (VAC). We report the characterization of a T. gondii null mutant for the TgVP1 gene. Propagation of these mutants decreased significantly because of deficient attachment and invasion of host cells, which correlated with deficient microneme secretion. Processing of cathepsin L (CPL) in these mutants was deficient only when the parasites were incubated in the presence of low concentrations of the vacuolar H(+) -ATPase (V-H(+) -ATPase) inhibitor bafilomycin A1 , suggesting that either TgVP1 or the T. gondii V-H(+) -ATPase (TgVATPase) are sufficient to support CPL processing. The lack of TgVP1 did not affect processing of micronemal proteins, indicating that it does not contribute to proMIC maturations. The TgVP1 null mutants were more sensitive to extracellular conditions and were less virulent in mice. We demonstrate that T. gondii tachyzoites possess regulatory volume decrease capability during hypo-osmotic stress and this ability is impaired in TgVP1 null mutants implicating TgVP1 in osmoregulation. We hypothesize that osmoregulation is needed for host cell invasion and that TgVP1 plays a role during the normal lytic cycle of T. gondii.

Abstract
PURPOSE Diffusion-weighted imaging (DWI) may improve the diagnostic performance of conventional breast magnetic resonance imaging (MRI). Diffusion tensor imaging (DTI) is an extension of DWI. If DTI-derived measurements are to be clinically useful, particularly for predicting and/or monitoring therapeutic effects, they must be robust and reliable. The purpose of this study was to assess intra- and interobserver reproducibility of DTI-derived fractional anisotropy (FA) and apparent diffusion coefficient (ADC) at 3.0 T. MATERIALS AND METHODS This prospective study was approved by the Institutional Review Board, and participants provided written informed consent. Sixty normal contralateral breasts of 60 patients (28-85 years, median 57) were analysed with a DWI sequence following a standard MRI protocol. Four authors performed all postprocessing and analyses independently and in different sessions. The same authors, blinded to the initial results, repeated the image postprocessing and analysis 4 weeks after the initial session. RESULTS Mean ADC and FA for DTI sequences were, respectively, 1.92±0.30 and 0.32±0.09. Intra- and interobserver agreement of the four radiologists for ADC and FA were good (acceptable). Kappa values for ADC were intra-R1=0.82; intra-R2=0.84; intra-R3=0.89; intra-R4=0.88; inter-R1-R2=0.73; inter-R1-R3=0.74; inter-R1-R4=0.81; inter-R2-R3=0.76; inter-R2-R4=0.77; inter-R3-R4=0.83. Kappa values for FA were intra-R1=0.60; intra-R2=0.72; intra-R3=0.84; intra-R4 = 0.66; inter-R1-R2=0.64; inter-R1-R3=0.69; inter-R1-R4=0.72; inter-R2-R3=0.80; inter-R2-R4=0.71; inter-R3-R4=0.73. Within-subject coefficient of variation was 15% for ADC and 30% for FA. Repeatability with α=0.05 was 0.37×10-3 mm(2)/s for ADC and 0.112 for FA. CONCLUSIONS ADC and FA measurements obtained with DTI are reproducible and may be valid, reliable and sensitive to change. ADC values obtained with DTI are more reproducible than FA.

Abstract
OBJECTIVE (a) To compare the efficacy of low-activity (2 GBq; 54 mCi) (131)I ablation using l-thyroxine withdrawal or rhTSH stimulation, and (b) to assess the influence of thyroid remnants volume on the ablation rate. DESIGN Patients underwent neck ultrasound, (131)I neck scintigraphy and radioiodine uptake. Post-therapy whole body scan (WBS) was acquired after 4-6 days. Ablation was assessed after 6-12 months by WBS, Tg and TgAb following l-thyroxine withdrawal. METHODS Group A: preparation by L-T(4) withdrawal (37 days); 21 patients received (131)I (2.02+/-0.22 GBq; 54.6+/-5.9 mCi) and on the day of treatment, TSH, Tg, TgAb were measured; Group B: stimulation by rhTSH; 21 patients received (131)I (1.97+/-0.18 GBq; 53.2+/-4.9 mCi) 24 h after the second injection of rhTSH (0.9 mg) and TSH, Tg and TgAb were measured after 2 days. RESULTS At follow-up, 90.0% of patients from group A and 85.0% of patients from group B had Tg levels <1 ng/ml; no uptake was observed in 95.2% and in 90.5% of patients from group A or B respectively, with no statistical differences for both ablation criteria. Before (131)I treatment, small thyroid remnants (<1 ml) were detected by US in <25% of all patients. CONCLUSIONS The use of rhTSH for the preparation of low-risk patients to ablation therapy with low activities of (131)I (2 GBq; 54 mCi) is safe and effective and avoids hypothyroidism. The presence of thyroid remnants smaller than 1 ml at US evaluation had no effect on the ablation rate.

Abstract
OBJECTIVE To study the immunogenicity and reactogenicity of a combined Haemophilus influenzae type b and Neisseria meningitidis serogroup C tetanus toxoid conjugate vaccine (Hib-MenC-TT) when administered as a booster dose in combination with a measles, mumps and rubella vaccine (MMR). DESIGN A phase 3 open randomised controlled trial. SETTING One centre in Oxford, UK and nine centres in Poland. SUBJECTS 12-15-month-old healthy children. INTERVENTIONS In the primary stage of the study 500 healthy 6-12-week-old infants were randomised in a 3:1 ratio to receive Hib-MenC-TT+DTPa-IPV or MenC-CRM197 vaccine+DTPa-IPV-Hib. In the booster stage, 476 participants (190 in the UK and 286 in Poland) were vaccinated with Hib-MenC-TT and MMR. MAIN OUTCOME MEASURES The proportion of children with protective serum antibody levels against MenC and Hib 6 weeks following a Hib-MenC-TT booster dose. RESULTS The co-primary objectives were met: the Hib-MenC-TT booster dose induced protective antibody titres in children vaccinated with Hib-MenC-TT+DTPa-IPV or MenC-CRM197+DTPa-IPV-Hib at 2, 3 and 4 months of age. 94.8% (lower limit of (LL) 95% CI 92.4) of participants had rSBA-MenC >or=1:128 and 100% (LL 95% CI 99.2) achieved anti-PRP concentrations >or=1.0 microg/ml. The percentage of toddlers with a post boost rSBA-MenC of 1:128 was significantly higher after priming with Hib-MenC-TT (97.7%) than after MenC-CRM197 (86%) (difference: 11.7%; 95% CI 6.2 to 19.4). CONCLUSION The waning antibody titres against Hib and MenC following primary immunisation can be boosted to protective levels by administering the Hib-MenC-TT vaccine at 12-15 months of age, supporting the recent introduction of this vaccine in the UK immunisation schedule to sustain protection of children against Hib and MenC disease. TRIAL REGISTRATION NUMBER NCT00258700. Study ID: 103974 (http://clinicaltrials.gov).

Abstract
Preschoolers play an important role in the transmission of influenza, and suffer significant morbidity. Paediatric vaccination could prevent serious outcomes and offer broader societal benefits. This study explored parental views on influenza and paediatric vaccination and determined the uptake of a nursery-based vaccination programme for infants aged 6-23 months. Children were offered two doses of inactivated vaccine in 2004/05, and a single dose at the start of the 2005/06 season. An uptake rate of 11% (60/535) was achieved with 83% (50/60) of participants completing the programme. Semi-structured interviews were conducted with 10 parents. Thematic analysis of the data informed the development of a questionnaire. This was distributed to 650 parents, with children aged 6-30 months attending one of the 18 supporting nurseries. A response rate of 13% (83/650) was achieved. The low uptake rate achieved in the programme and findings from the interviews/questionnaire suggest parents were not convinced about the seriousness of paediatric influenza. Indeed, over two-thirds (55/81) questioned the necessity for an annual vaccination. Parents found it difficult to differentiate influenza from other respiratory illnesses, and expressed concerns about the need for annual injections and vaccine safety. Paediatric vaccination to increase herd immunity was held in balance with the notion that children should only be vaccinated if they are the main beneficiaries. Parental education on the burden of childhood influenza, on the direct benefits of influenza vaccination, and on indirect benefits to society is a necessity for a successful paediatric vaccination programme.

Abstract
We set out to determine if essay writing on health advocacy could improve scores on a Health Advocacy observed structured clinical exam (OSCE) station.
A Health Advocacy station was used as one of ten stations at the annual resident OSCE in 2006. Subsequently, residents were instructed to write an essay regarding their actions as a health advocate, either in general or relating to a specific situation. For the 2007 OSCE, a different Health Advocacy station was used that was similar to the previous year in terms of the issues that residents needed to address and the scoring structure. The results on the OSCE stations between the two years were compared using Student’s T-test. Regression analysis was used to identify any predictors for a higher score.
The number of residents taking the OSCE in 2006 and 2007 were 17 and 13, respectively. Nine residents completed the OSCE in both years. The number of PGY-1’s taking the OSCE for the first time in 2006 and 2007 were 8 and 4, respectively. Compliance with the essay writing was 100%. The mean score on the Health Advocacy station was significantly higher in 2007 compared to 2006 (53.0 ± 14.6 compared to 65.6 ± 10.0 vs. 53.0 ± 14.6; p=0.01). The mean score of PGY-1’s in 2007 tended to be higher than PGY-1’s in 2006 (67.5 ± 11.4 vs. 54.5 ± 12.3; p=0.11), suggesting the improvement was not due to having taken the OSCE previously. Regression analysis did not identify and other predictors of higher score on the OSCE station.
These results suggest that essay writing by residents about actions they have taken as health advocates improves knowledge about the CanMEDS competency of Health Advocacy, as measured in an OSCE station. The non-randomized design of the study does not exclude the possibility of other factors influencing the improvement in score.

62. Does an expert presentation raise awareness of CanMEDs Roles among residents?s. CLIN INVEST MED 2007.

Abstract
We set out to determine whether an expert presentation on CanMEDS would raise awareness of CanMEDS roles among residents. We addressed this question with paired surveys distributed before and after the expert presentation.
Each survey outlined seven different clinical scenarios each of which required one of the seven core CanMEDS competencies. Paired surveys were distributed prior to the presentation to the audience that was composed of a selection of residents from various disciplines. One survey was filled out prior to and the second survey completed following the expert presentation.
Data were analysed using nonparamentric statistical methods. There was in general, a low pre-presentation background knowledge of CanMEDS roles, with wide variability between specialties. Our hypothesis that disciplines with less patient contact would have less understanding of CanMEDS roles was not fully supported. All specialties demonstrated improvement in their understanding of CanMEDS roles in the post-presentation survey.
While there is a low background level of knowledge about CanMEDS roles, we determined that following an expert presentation (in this case by Dr. Serita Verma) the residents were significantly more able to correctly apply the core competencies of the CanMEDS model to the given clinical scenarios. We propose that an expert presentation could be applied as an innovative educational tool advancing CanMEDS education among residents.

Sphingosine releases Ca2+ from intracellular stores via the ryanodine receptor in sea urchin egg homogenates. Biochem Biophys Res Commun 2005; 338:1316-21.

Abstract
Various reports have demonstrated that the sphingolipids sphingosine and sphingosine-1-phosphate are able to induce Ca2+ release from intracellular stores in a similar way to second messengers. Here, we have used the sea urchin egg homogenate, a model system for the study of intracellular Ca2+ release mechanisms, to investigate the effect of these sphingolipids. While ceramide and sphingosine-1-phosphate did not display the ability to release Ca2+, sphingosine stimulated transient Ca2+ release from thapsigargin-sensitive intracellular stores. This release was inhibited by ryanodine receptor blockers (high concentrations of ryanodine, Mg2+, and procaine) but not by pre-treatment of homogenates with cADPR, 8-bromo-cADPR or blockers of other intracellular Ca2+ channels. However, sphingosine rendered the ryanodine receptor refractory to cADPR. We propose that, in the sea urchin egg, sphingosine is able to activate the ryanodine receptor via a mechanism distinct from that used by cADPR.

Abstract
OBJECTIVES To describe the technique and compare the surgical outcomes of patients with autosomal dominant polycystic kidney disease (ADPKD) undergoing laparoscopic or open nephrectomy for giant kidneys. METHODS The surgical outcome of our first 10 consecutive patients with ADPKD who underwent laparoscopic nephrectomy was analyzed from a large prospective computer database. The results were compared with the 10 most recent open nephrectomy procedures performed for ADPKD at the same institution. To facilitate safe laparoscopic hilar dissection, the kidneys were made manageable by volume reduction, accomplished through diligent cyst puncture and aspiration using a novel prototype suction device with a beveled tip. RESULTS No statistically significant differences were found between the laparoscopic and open surgical groups relative to patient sex, age, or median preoperative kidney size (24.0 versus 21.5 cm, respectively). The laparoscopic patients were significantly heavier than their open counterparts (94 versus 78 kg, P = 0.0095) and had a longer operative time (247 versus 205 minutes, P = 0.04). One conversion to open surgery occurred in the laparoscopic group because cysts were adherent to the spleen and colonic mesentery. No intraoperative complications or deaths occurred in either group and the postoperative complications were similar. The mean length of the postoperative hospitalization was markedly reduced with the laparoscopic compared with the open approach (2.6 versus 6.6 days, P = 0.00002). At a median of 12 months after surgery, none of the laparoscopic patients had recurrent pain, bleeding, or infection. CONCLUSIONS Laparoscopic nephrectomy is technically safe and feasible in patients with ADPKD. Progressive cyst aspiration is a critical step, facilitating the identification of vital structures and the creation of enough abdominal cavity space to operate. The advantages of this minimally invasive technique include a short hospital stay, minimal pain, low morbidity, and superior cosmesis.

Abstract
OBJECTIVES After 10 d of orlistat administration (120 mg three times/day), the primary objective was to determine the drug's effect on postprandial plasma lipoprotein lipase (LPL) and hepatic triglyceride lipase (HTGL) activities on day 10 after an oral fat-load. The secondary objectives were to determine the effects of orlistat on 12 h postprandial measures of: (1) preheparin HTGL and LPL; and (2) serum triglycerides, very-low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and free fatty acids. METHODS Twenty-four normal-weight, healthy male volunteers were randomized to either 120 mg orlistat (n=12) or placebo (n=12) three times a day with meals for 10 d. Preheparin LPL and HTGL activities and LPL specific activity were measured in the fasted state on days 1, 5, and 10. On days 5 and 10 the study medication (orlistat or placebo) was taken at the beginning of a fat-rich breakfast and serum lipid and lipoprotein levels monitored for 12 h postprandially. On day 10, 15 min postheparin HTGL activity was measured 8 h after the fat-rich breakfast. RESULTS No differences were found between groups in fasting levels of preheparin LPL or HTGL activity or in LPL-specific activity on days 1, 5 and 10. No difference was found between the two treatment groups in postheparin HTGL activity 8 h after the fat-rich breakfast. Also, no differences were found between the two groups in plasma triglycerides or lipoproteins. CONCLUSION The results indicate that the oral administration of orlistat (120 mg t. i.d.) does not significantly alter plasma triglycerides or lipoproteins, and that the inhibitory effect of orlistat on lipases is limited to the gastrointestinal tract and is not manifested systemically.

Abstract
OBJECTIVES To assess the consequences of physician delay in the diagnosis of breast cancer by comparing stage, treatment, and outcome of patients with and without delay, and to identify patient characteristics that may make diagnosis more difficult. SUMMARY BACKGROUND INFORMATION: Delay in diagnosis of breast cancer is the most common clinical scenario resulting in malpractice litigation. METHODS The records of 1014 patients were reviewed and the events preceding the diagnosis were reconstructed. Accurate assessment of the physician delay in diagnosis could be made for 606 patients, 51 (8%) with physician delay >3 months. Patients with delay were comparable to patients without delay in terms of age, height, weight, age at menarche, pregnancies, children, proportion in menopause, age at menopause, and family history of breast cancer. RESULTS Thirty-six percent of patients who had a delay in diagnosis had normal mammograms versus 7% of patients without delay. Cancers in patients with delay were significantly larger on average than in those without delay, but there were no significant differences in pathology, differentiation, nodal status, TNM stage, treatment, or outcome. CONCLUSIONS Physician delay in the diagnosis of breast cancer is common, and patients with delay are similar to patients without delay, although they are more likely to have normal mammograms. The consequences of physician delay in terms of stage at diagnosis, treatment, and outcome were not statistically significant.

Abstract
OBJECTIVES The degree and duration of protection against exercise-induced bronchoconstriction afforded by three doses of a specific leukotriene D4 receptor antagonist, cinalukast, were assessed after an initial dosing and after 1 week of therapy. METHODS A placebo-controlled crossover study was performed in eight male patients who had mild, stable asthma and exercise-induced bronchoconstriction. Treatment consisted of four 7-day periods of placebo and three dose levels of the drug (10, 50, and 200 mg administered orally). Exercise challenge was performed at 2 hours and 8 hours after treatment on the first and seventh treatment days. The response was measured as the area under the FEV1-time effect curve (AUEC). RESULTS On the first day of treatment, the mean (+/- SEM) AUEC at 2 hours was 24.2 +/- 3.3 L.min after placebo and was 5.5 +/- 2.2 L.min, 6.3 +/- 2.7 L.min, 3.3 +/- 3.8 L.min after 10 mg, 50 mg, and 200 mg, respectively (p < 0.05 for all values compared with placebo). The AUEC at 8 hours on the first day was 25.1 +/- 4.4 L.min after placebo and was 6.8 +/- 4.1 L.min, 11.2 +/- 2.5 L.min, and 5.0 +/- 2.8 L.min after 10 mg, 50 mg, and 200 mg, respectively (p < 0.05 for all values compared with placebo). The protection afforded by 10 mg of cinaluicast was lost after 7 days of treatment but persisted with 50 mg and 200 mg doses. CONCLUSION Orally administered cinalukast provides at least 8 hours of protection against exercise-induced bronchoconstriction. This protection is lost with regular treatment for 1 week for the lowest dose studied.

Abstract
Recurrent respiratory infections (RRI) consist of more relapsing acute respiratory infections than the ones expected for the age [> 6 acute respiratory tract infections (RTI) per year if age is > 3 years, and > 8 acute RTI per year if age is < 3 years]. Concerning the pathogenesis of RRI, several investigations report the important role of environmental factors, early socialization and immunological dysfunctions, such as lymphocyte subpopulations alterations, IgG subclass deficiency and phagocytosis and/or opsonization deficit during acute infections. In this framework, we have studied the lymphocyte-dependent antibacterial activity (ABA) among 121 children affected by RRI. Results show a statistically significant alteration of this function in 38 children (31.4%): 19 of them exhibited an absent ABA (group 1), while in the others same function was reduced (group 2). A bovine thymic extract, thymostimulin, was administered to both groups by intramuscular injections (1 mg/kg) for a 3 month cycle. At the end of therapy we observed a statistical significant rise of ABA only in group 1 and among children aged > 3 years. Among the same patients, 33 children (86.8%) improved in terms of reduction of clinical score and better results were seen among children aged > 3 years. These data emphasize the beneficial role of thymostimulin in RRI-affected children, suggesting a transient immaturity of the immune system as one of the possible pathogenetic factor.

Abstract
Granulated lymphocytes with an unusual antigenic phenotype (CD56+ CD38+ CD2 +/- CD3- CD16-) form a substantial proportion of leukocytes in human endometrial stroma. The purpose of this study was to examine morphological and antigenic heterogeneity in endometrial granulated lymphocytes (eGL) in imprint preparations, paraffin-embedded sections and frozen sections. eGL in decidual imprints showed variations in cell size, nuclear size, shape and chromatin content and the number and size of cytoplasmic granules. eGL were detected in paraffin-embedded sections using phloxine tartrazine, alcian blue and toluidine blue stains. There was no difference in the number of eGL among the three stains but the granules appeared smaller and more regular when stained with toluidine blue. The proportion of stromal cells which were leukocytes increased from 8.2% in proliferative endometrium to 31.7% in early pregnancy decidua. The number of CD56+ and CD38+ cells increased in late secretory endometrium; CD56+ cells formed greater than 75% of the leukocytes in first trimester decidua. The increased number of CD2+ cells in decidua was not comparable with CD56+ and CD38+ cells suggesting that a lower proportion of CD56+ cells in first trimester decidua coexpress CD2, an observation which was supported by double labelling studies. eGL therefore show morphological and antigenic heterogeneity and the study of granulated lymphocytes in pathological endometrium and decidua will require careful phenotypic and morphological analysis of accurately dated samples.

Abstract
Intraepithelial lymphocytes (IELs) were characterized and quantitated in normal non-pregnant endometrium and in early pregnancy decidua using H & E and phloxine tartrazine stains and a panel of monoclonal antibodies in an indirect immunoperoxidase technique. The relative numbers of granulated and non-granulated IELs varied according to menstrual cycle stage and in early pregnancy all IELs appeared to be granulated. There was a higher surface:gland ratio for IELs in proliferative endometrium compared with late secretory phase and early pregnancy endometrium. In proliferative endometrium most IELs were T cells, predominantly of the CD8 + subset. In first trimester decidua, higher numbers of CD56 + cells were observed, in keeping with the increased proportion of granulated IELs. IEL populations in human endometrium vary according to menstrual cycle stage and endometrial IELs appear to show phenotypic differences compared with IELs in the human gastrointestinal tract.

Abstract
The proliferative activity in endometrial stromal granulocytes was studied using two approaches. Firstly, mitotic activity was studied in paraffin wax embedded sections of normal non-pregnant endometrium and early pregnancy decidua stained with phloxine-tartrazine. Secondly, the monoclonal antibody Ki67 was applied to cryostat sections of similar tissues. Endometrial stromal granulocytes were identified by their labelling with NKH1, Dako T11, UCHL1 or Dako-LC. The percentage of cases in which endometrial stromal granulocytes showed mitosis was 25%, 75%, 86%, and 93%, respectively in proliferative, early secretory, mid secretory, and late secretory phases, and 14% in early decidua. There were at most one or two endometrial stromal granulocytes in mitosis per 10 high power fields. Double labelled cells were present in small numbers in proliferative endometrium and in moderate numbers in secretory endometrium. Only a few cells in early decidua double labelled with Ki67/T11; moderate numbers of cells double labelled with Ki67/Dako-LC. It is concluded that proliferative activity does occur in endometrial stromal granulocytes and is particularly prominent in the late secretory phase.

Abstract
Suggestions that local intrauterine materno-fetal immune interactions may be important for normal pregnancy have led to investigation of immunoregulatory function by decidualised endometrium. Human decidua is complex and cell types may be difficult to distinguish at the light microscope level. Immunohistochemical techniques have allowed antigenic identification of cells within decidua and abundant leucocytes are present throughout pregnancy. Macrophages (CD14+) are abundant in decidua basalis and decidua parietalis throughout pregnancy and may be closely associated with extravillous trophoblast. Expression of class II MHC antigens and CD11c may suggest an immunological role but their content of lysosomal enzymes could indicate phagocytic functions. Antigen-presenting capacity has been noted in early human decidua and may be due to macrophages. Decidual macrophages have also been attributed with immunosuppressive function due to secretion of prostaglandin E2. Decidual granulated lymphocytes are abundant in the first trimester and correspond to the so-called endometrial stromal granulocytes. They express CD2, CD7, CD38 and NKH1 but are negative for classical T cell and NK cell markers and they do not express the IL2 receptor. Semipurified populations show low levels of cytotoxicity in a standard NK assay. Thus, immunohistochemical techniques have allowed characterisation of potentially immunocompetent cells in human decidua. However, their roles both in vitro and in vivo remain to be established with certainty.

Abstract
Superoxide dismutase (SOD) and catalase (CAT), enzymes that degrade superoxide anion and hydrogen peroxide, respectively, reduce size of infarction in anesthetized, open-chest dogs subjected to coronary occlusion followed by reperfusion. To evaluate potential protective effects of these enzymes in conscious animals, three groups of dogs were instrumented at sterile surgery with a hydraulic occluder on the left circumflex (LCX) coronary artery, sonomicrometers to measure regional wall thickness, and catheters to monitor arterial and left ventricular pressures. Ten to 14 days after surgery, the animals were sedated with morphine sulfate (0.5 mg/kg). The LCX artery was occluded for 3 hr by inflation of the hydraulic cuff. Infusions of SOD (n = 7), CAT (n = 6), or saline (control group, n = 7) were begun 15 min before reperfusion and lasted for 45 min of reperfusion. The doses of SOD and CAT were 5 mg/kg, dissolved in 60 ml of saline, and infused at a rate of 1 ml/min. Myocardial blood flow was measured with tracer-labeled microspheres (15 micron diameter) before occlusion, after 5 to 10 min of occlusion, after 150 min of occlusion, and 5 to 10 min after reperfusion. Size of infarction was measured 24 hr later by dual-perfusion staining with Evans blue and triphenyl tetrazolium. Size of infarction (expressed as a percentage of area at risk) did not differ significantly among the three groups: control, 32 +/- 17% (mean +/- SD); SOD, 38 +/- 17%; CAT, 27 +/- 17%. Hemodynamic parameters and myocardial blood flows (measured before infusion of any agents) were not significantly different among the three groups. Serum SOD levels in SOD-treated dogs were 19 +/- 2 micrograms/ml at the onset of reperfusion and 29 +/- 3 micrograms/ml at the end of the infusion. Blood assays collected after infusion showed a monoexponential decay of SOD levels with a half-life of 22 +/- 6 min. We conclude that myocardial protection by SOD or CAT is model dependent. In conscious dogs subjected to 3 hr of coronary occlusion followed by reperfusion, SOD and CAT failed to alter size of infarction.

Abstract
A microsomal metabolite of cibenzoline, 4,5-dihydro-2-(2,2-diphenylcyclopropyl)-1H-imidazole butanedioate, was identified by n.m.r. as the 4,5-dehydro analogue, 2-(2,2-diphenylcyclopropyl)-1H-imidazole. Three dogs dosed orally with 13.8 mg/kg 14C-cibenzoline base excreted 1.8-3.5% of the dose as this metabolite in the urine. Mean plasma concentrations of cibenzoline reached a peak of 1.5 micrograms/ml at 2 h while mean concentrations of the metabolite of 0.4-0.5 micrograms/ml were found between 2 and 7 h. The metabolite was synthesized and found to decrease the frequency of ventricular premature depolarizations in conscious dogs having a two-stage occlusion of the left anterior descending coronary artery performed 48 h before. It did not inhibit ventricular arrhythmia in rats induced by i.v. infusion of aconitine. Thus, in contrast to cibenzoline, the metabolite does not appear to be a true antiarrhythmic agent.

Abstract
Genetic, clinical, polyphysiographic and therapeutical aspects were investigated in a 37 year old patient suffering from: sporadic and localized segmentary myoclonia (present during rest and increasing slightly during movement), cerebellar syndrome, marked hypoacusia, hyper-reflexia of the lower limbs, spike and polyspike EEG discharges and massive myoclonia during photostimulation. A dominant autosomic inheritance of this syndrome was suggested by the occurrence of a more serious and rapid, yet similar, illness in the mother and by EEG alterations in an 8 year old son. The Authors suggest that, from the clinical point of view, they are dealing with an atypical Ramsay-Hunt syndrome (MCD) with signs of Pierre-Marie Heredoataxia. This supports the possibility, however rare, of intermediate forms between MCD and Heredoataxia. The patient underwent polyphysiographic investigations under the following conditions: i) without therapy; ii) with diphenylhydantoin; iii) with phenobarbital; iv) with sodium dipropyl-acetate; v) with clonazepam. The above investigations confirmed the previously described alterations, during wakefulness or sleep, observed in cases of Unverricht-Lundborg syndrome (PME) and Ramsay-Hunt syndrome (MCD). Clonazepam was found to be the most effective drug in attenuating myoclonia, in reducing the EEG spike activity and in reorganizing the phases and cycles of sleep.
