Background: Efforts to improve end of life care (EoLC) have made tangible impacts on care in adults, including enabling more people to die at their preferred place of death (PoD), usually home or hospices. Little is known how the PoD in children and young people (CYP, ≤24 years) has changed over time, especially in the context of a series of national initiatives for EoLC improvement since the late 1990s. To inform evidence-based policy-making and service development, we evaluated the national trends of PoD and the associated factors in CYP who died with cancer.Methods: Population-based observational study in the National Health Service (NHS) England, 1993-2014. All non-accidental CYP deaths with cancer (N = 12,774) were extracted from the death registration database of the Office for National Statistics (ONS).Results: Hospital deaths reduced from >50 to 45 %, hospice deaths were rare but more than doubled from 6 % in 1993-2000 to 13 % in 2005-2014, and home deaths fluctuated at around 40 %. Those aged 0-19 years were more likely to die at home than young adults (adjusted proportion ratio (PRs): 1.23-1.62); haematological cancer patients or those with 2+ comorbid conditions had higher chances of hospital death (PRs for home: 0.18-0.75, hospice: 0.04-0.37); deprivation was associated with a reduced chance of home death (PRs: 0.76-0.84). The residential region affected hospice but not home deaths. The variations of PoD by cause of death, comorbid conditions and deprivation slightly decreased with time.Conclusions: Hospitals and home were the main EoLC settings for CYP with cancer. Home death rates barely changed in the past two decades; deaths in hospitals remained the most common but slightly shifted towards hospices. CYP with haematological malignancy or with comorbid conditions had persistently high hospital deaths; these cases had an even lower chance of deaths in hospices (50 %) than at home. There were deprivation- and area-related inequalities in PoD which may need service- and/or policy-level intervention. The findings highlight a need for CYP specific initiatives to enhance EoLC support and capacities both at home and in hospices. [ABSTRACT FROM AUTHOR]

Background: Patients affected by progressive long-term neurological conditions might benefit from specialist palliative care involvement. However, little is known on how neurology and specialist palliative care services interact. This study aimed to map the current level of connections and integration between these services.Methods: The mapping exercise was conducted in eight centres with neurology and palliative care services in the United Kingdom. The data were provided by the respective neurology and specialist palliative care teams. Questions focused on: i) catchment and population served; ii) service provision and staffing; iii) integration and relationships.Results: Centres varied in size of catchment areas (39-5,840 square miles) and population served (142,000-3,500,000). Neurology and specialist palliative care were often not co-terminus. Service provisions for neurology and specialist palliative care were also varied. For example, neurology services varied in the number and type of provided clinics and palliative care services in the settings they work in. Integration was most developed in Motor Neuron Disease (MND), e.g., joint meetings were often held, followed by Parkinsonism (made up of Parkinson's Disease (PD), Multiple-System Atrophy (MSA) and Progressive Supranuclear Palsy (PSP), with integration being more developed for MSA and PSP) and least in Multiple Sclerosis (MS), e.g., most sites had no formal links. The number of neurology patients per annum receiving specialist palliative care reflected these differences in integration (range: 9-88 MND, 3-25 Parkinsonism, and 0-5 MS).Conclusions: This mapping exercise showed heterogeneity in service provision and integration between neurology and specialist palliative care services, which varied not only between sites but also between diseases. This highlights the need and opportunities for improved models of integration, which should be rigorously tested for effectiveness. [ABSTRACT FROM AUTHOR]

ASPECT-NP, a phase 3 trial of ceftolozane/tazobactam in hospital-acquired/ventilator-associated bacterial pneumonia (HABP/VABP), excluded patients with end-stage renal disease (ESRD). A modeling/simulation approach was undertaken to inform optimal dosing in this population, using previously developed ceftolozane and tazobactam population pharmacokinetic models informed by data from 16 clinical studies. Stochastic simulations were performed using NONMEM to support dose justification. Probability of target attainment (PTA) simulations in plasma and epithelial lining fluid were conducted using a 14-day treatment, with hemodialysis every other weekday for a high-dose (4X), middle-dose (3X), or low-dose (2X) regimen, where X was the recommended dose in patients with complicated intra-abdominal infection/complicated urinary tract infection and ESRD (500 mg/250 mg ceftolozane/tazobactam loading dose and 100 mg/50 mg ceftolozane/tazobactam maintenance dose administered by 1-hour infusion every 8 hours). PTA was determined using established pharmacokinetic/pharmacodynamic targets: ceftolozane, 30% of the interdose interval (8 hours) in which free ceftolozane concentration exceeded the minimum inhibitory concentration value of 4 µg/mL; tazobactam, 20% of the interdose interval in which free tazobactam concentration exceeded 1 µg/mL. Plasma PTA was >90% for both agents for all 3 regimens. Plasma ceftolozane exposures at the high-dose regimen exceeded those from phase 3 study experience. Epithelial lining fluid PTA was >90% for high- and middle-dose regimens but was <80% for tazobactam on dialysis days at the low-dose regimen. For patients with HABP/VABP and ESRD requiring intermittent hemodialysis, the middle-dose regimen of 1.5 g/0.75 g ceftolozane/tazobactam loading + 300 mg/150 mg maintenance every 8 hours by 1-hour infusion is recommended.

Objective: To investigate the prevalence and natural course of pulmonary cysts in a population-based cohort and to describe the CT image characteristics in association with participant demographics and pulmonary functions.Materials and Methods: Chest CT scans of 2633 participants (mean age 59.2 years; 50% female) of the Framingham Heart Study (FHS) were visually evaluated for the presence of pulmonary cysts and their image characteristics. These findings were correlated with participant demographics and results of pulmonary function tests as well as the presence of emphysema independently detected on CT. The interval change was investigated by comparison with previous CT scans (median interval 6.1 years).Results: Pulmonary cysts were seen in 7.6% (95% CI 6.6% to 8.7%; 200/2633). They were not observed in participants younger than 40 years old, and the prevalence increased with age. Multiple cysts (at least five) were seen in 0.9% of all participants. Participants with pulmonary cysts showed significantly lower body mass index (BMI) (p<0.001). Pulmonary cysts were most likely to appear solitary in the peripheral area of the lower lobes and remain unchanged or slightly increase in size over time. Pulmonary cysts showed no significant influence on pulmonary functions (p=0.07-0.6) except for diffusing capacity of the lung for carbon monoxide (DLCO) (p=0.03) and no association with cigarette smoking (p=0.1-0.9) or emphysema (p=0.7).Conclusions: Pulmonary cysts identified on chest CT may be a part of the aging changes of the lungs, occurring in asymptomatic individuals older than 40 years, and are associated with decreased BMI and DLCO. Multiple pulmonary cysts may need to be evaluated for the possibility of cystic lung diseases. [ABSTRACT FROM AUTHOR]

Tai Chi Chuan (TCC), a traditional Chinese martial art, is well-documented to result in beneficial consequences in physical and mental health. TCC is regarded as a mind-body exercise that is comprised of physical exercise and meditation. Favorable effects of TCC on body balance, gait, bone mineral density, metabolic parameters, anxiety, depression, cognitive function, and sleep have been previously reported. However, the underlying mechanisms explaining the effects of TCC remain largely unclear. Recently, advances in neuroimaging technology have offered new investigative opportunities to reveal the effects of TCC on anatomical morphologies and neurological activities in different regions of the brain. These neuroimaging findings have provided new clues for revealing the mechanisms behind the observed effects of TCC. In this review paper, we discussed the possible effects of TCC-induced modulation of brain morphology, functional homogeneity and connectivity, regional activity and macro-scale network activity on health. Moreover, we identified possible links between the alterations in brain and beneficial effects of TCC, such as improved motor functions, pain perception, metabolic profile, cognitive functions, mental health and sleep quality. This paper aimed to stimulate further mechanistic neuroimaging studies in TCC and its effects on brain morphology, functional homogeneity and connectivity, regional activity and macro-scale network activity, which ultimately lead to a better understanding of the mechanisms responsible for the beneficial effects of TCC on human health.

Background: Strategies in many countries have sought to improve palliative care and reduce hospital deaths for non-cancer patients, but their effects are not evaluated. We aimed to determine the trends and factors associated with dying in hospital in two common progressive respiratory diseases, and the impact of a national end of life care (EoLC) strategy to reduce deaths in hospital.Methods: This population-based observational study linked death registration data for people in England dying from chronic obstructive pulmonary disease (COPD) or interstitial pulmonary diseases (IPD). We plotted age- and sex-standardised trends, assessed during the pre-strategy (2001-2004), first strategy phase (2004-2008), and strategy intensification (2009-2014) periods, and identified factors associated with hospital death using multiple adjusted proportion ratios (PRs).Results: Over 14 years, 380,232 people died from COPD (334,520) or IPD (45,712). Deaths from COPD and IPD increased by 0.9% and 9.2% annually, respectively. Death in hospital was most common (67% COPD, 70% IPD). Dying in hospice was rare (0.9% COPD, 2.9% IPD). After a plateau in 2004-2005, hospital deaths fell (PRs 0.92-0.94). Co-morbidities and deprivation independently increased the chances of dying in hospital, with larger effects in IPD (PRs 1.01-1.55) than COPD (PRs 1.01-1.39) and dose-response gradients. The impact of multimorbidity increased over time; hospital deaths did not fall for people with two or more co-morbidities in COPD, nor one or more in IPD. Living in rural areas (PRs 0.94-0.94) or outside London (PRs, 0.89-0.98) reduced the chances of hospital death. In IPD, increased age reduced the likelihood of hospital death (PR 0.81, ≥ 85 versus ≤ 54 years); divergently, in COPD, being aged 65-74 years was associated with increased hospital deaths (PR 1.13, versus ≤ 54 years). The independent effects of sex and marital status differed for COPD versus IPD (PRs 0.89-1.04); in COPD, hospital death was associated with being married.Conclusions: The EoLC strategy appeared to have contributed to tangible reductions in hospital deaths, but did not reach people with multimorbidity and this gap widened over time. Integrating palliative care earlier in the disease trajectory especially in deprived areas and cities, and where multimorbidity is present, should be boosted, taking into account the different demographic factors in COPD and IPD.

In response to clusters of carbapenem-resistant Enterobacteriaceae (CRE) in Illinois, USA, the Illinois Department of Public Health and the Centers for Disease Control and Prevention Chicago Prevention Epicenter launched a statewide Web-based registry designed for bidirectional data exchange among health care facilities. CRE occurrences are entered and searchable in the system, enabling interfacility communication of patient information. For rapid notification of facilities, admission feeds are automated. During the first 12 months of implementation (November 1, 2013-October 31, 2014), 1,557 CRE reports (≈4.3/day) were submitted from 115 acute care hospitals, 5 long-term acute care hospitals, 46 long-term care facilities, and 7 reference laboratories. Guided by a state and local public health task force of infection prevention specialists and microbiologists and a nonprofit informatics entity, Illinois Department of Public Health deployed a statewide registry of extensively drug-resistant organisms. The legal, technical, and collaborative underpinnings of the system enable rapid incorporation of other emerging organisms. [ABSTRACT FROM AUTHOR]

Background: An HIV-1 tropism test is recommended prior to CCR5 antagonist administration to exclude patients harboring non-R5 virus from treatment with this class of antiretrovirals. HIV-1 tropism determination based on proviral DNA (pvDNA) may be useful in individuals with plasma viral RNA suppression. We developed a genotypic tropism assay for pvDNA and assessed its performance in a retrospective analysis of samples collected longitudinally. Results: We randomly selected paired plasma/PBMC samples from the Women's Interagency HIV Study with plasma viral load ≥5,000 cp/mL at time 1 (T1), undetectable viral load maintained for ≥1 year and CD4+ >200 cells/pL at time 2 (T2). pvDNA was isolated from cryopreserved PBMCs. Sequences were analyzed in triplicate from 49/50 women, with tropism assigned using the geno2pheno (g2p) algorithm. The median time between T1 and T2 was 4.1 years. CXCR4-using virus was detected in 24% of the RNA samples and 33% of the pvDNA samples at T1, compared to 37% of the pvDNA samples at T2. Concordance between plasma RNA and pvDNA tropism was 88% at T1 and 80% at T2. The g2p scores for RNA (T1) vs DNA (T1, T2) were strongly correlated (Spearman rho: 0.85 (T1); 0.78 (T2)). In women with evidence of tropism switch at T2 (either R5 to non-R5 or non-R5 to R5), there was a correlation between change in tropism and time. Mean pvDNA viral load decreased by 0.4 log10 copies/106 cells between T1 and T2 (p < 0.0001), but this decrease was not significantly associated with tropism status. Conclusions: We demonstrated that pvDNA tropism in women with HIV-1 suppression is concordant with prior RNA tropism results, even after a median time of >4 years. pvDNA tropism testing may be useful to determine eligibility of patients with viral suppression to switch to a CCR5-antagonist based regimen as well as for research purposes.
