The NHS visitor and migrant cost recovery programme - a threat to health?

BACKGROUND: In April 2014 the UK government launched the 'NHS Visitor and Migrant Cost Recovery Programme Implementation Plan' which set out a series of policy changes to recoup costs from 'chargeable' (largely non-UK born) patients. In England, approximately 75% of tuberculosis (TB) cases occur in people born abroad. Delays in TB treatment increase risk of morbidity, mortality and transmission in the community. We investigated whether diagnostic delay has increased since the Cost Recovery Programme (CRP) was introduced. METHODS: There were 3342 adult TB cases notified on the London TB Register across Barts Health NHS Trust between 1st January 2011 and 31st December 2016. Cases with missing relevant information were excluded. The median time between symptom onset and treatment initiation before and after the CRP was calculated according to birthplace and compared using the Mann Whitney test. Delayed diagnosis was considered greater or equal to median time to treatment for all patients (79 days). Univariable logistic regression was used to manually select exposure variables for inclusion in a multivariable model to test the association between diagnostic delay and the implementation of the CRP. RESULTS: We included 2237 TB cases. Among non-UK born patients, median time-to-treatment increased from 69 days to 89 days following introduction of CRP (p < 0.001). Median time-to-treatment also increased for the UK-born population from 75.5 days to 89.5 days (p = 0.307). The multivariable logistic regression model showed non-UK born patients were more likely to have a delay in diagnosis after the CRP (adjOR 1.37, 95% CI 1.13-1.66, p value 0.001). CONCLUSION: Since the introduction of the CRP there has been a significant delay for TB treatment among non-UK born patients. Further research exploring the effect of policies restricting access to healthcare for migrants is urgently needed if we wish to eliminate TB nationally.

Protocol for a cluster randomised control trial evaluating the efficacy and safety of treatment for latent tuberculosis infection in recent migrants within primary care: the CATAPuLT trial.

BACKGROUND: The identification and treatment of LTBI is a key component of the WHO's strategy to eliminate TB. Recent migrants from high TB-incidence countries are recognised to be at risk TB reactivation, and many high-income countries have focused on LTBI screening and treatment programmes for this group. However, migrants are the group least likely to complete the LTBI cascade-of-care. This pragmatic cluster-randomised, parallel group, superiority trial investigates whether a model of care based entirely within a community setting (primary care) will improve treatment completion compared with treatment in specialist TB services (secondary care). METHODS: The CATAPuLT trial (Completion and Acceptability of Treatment Across Primary Care and the community for Latent Tuberculosis) randomised 34 general practices in London, England, to evaluate the efficacy and safety of treatment for LBTI in recent migrants within primary care. GP practices were randomised to either provide management for LTBI entirely within primary care (GPs and community pharmacists) or to refer patients to secondary care. The target recruitment number for individuals is 576. The primary outcome is treatment completion (defined as taking at least 90% of antibiotic doses). The secondary outcomes assess adherence, acceptance of treatment, the incidence of adverse effects including drug-induced liver injury, the rates of active TB, patient satisfaction and cost-effectiveness of LTBI treatment. This protocol adheres to the SPIRIT Checklist. DISCUSSION: The CATAPuLT trial seeks to provide implementation research evidence for a patient-centred intervention to improve treatment completion for LTBI amongst recent migrants to the UK. TRIAL REGISTRATION: NCT03069807, March 2017, registered retrospectively.

Prevalence of Obesity and Malnutrition in Four Cohorts of Very Old Adults, 2000-2017.

OBJECTIVES: Investigate trends in the prevalence of obesity and malnutrition among very old adults (age ≥ 85 years) between 2000 and 2017. DESIGN, SETTING, PARTICIPANTS, MEASUREMENTS: A study with data from the Umeå 85+/Gerontological regional database population-based cohort study of very old adults in northern Sweden. Every 5 years from 2000-2002 to 2015-2017, comprehensive assessments of participants were performed during home visits (N=1602). Body mass index (BMI) classified participants as underweight (<18.5 kg/m2), normal weight (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (≥30.0 kg/m2). Mini Nutritional Assessment (MNA) scores classified participants as malnourished (0 to <17), at risk of malnutrition (17-23.5), and having good nutritional status (24-30). Prevalence and trends were examined using analysis of variance and chi-squared tests, including subgroup analyses of nursing home residents. RESULTS: Between 2000-2002 and 2015-2017, the mean BMI increased from 24.8± 4.7 to 26.0± 4.7 kg/m2. The prevalence of obesity and underweight were 13.4% and 7.6%, respectively, in 2000-2002 and 18.3% and 3.0%, respectively, in 2015-2017. The mean MNA score increased between 2000-2002 and 2010-2012 (from 23.2± 4.7 to 24.2± 3.6), and had decreased (to 23.3± 4.2) by 2015-2017. The prevalence of malnutrition was 12.2%, 5.1%, and 8.7% in 2000-2002, 2010-2012, and 2015-2017, respectively. Subgroup analyses revealed similar BMI and MNA score patterns among nursing home residents. CONCLUSIONS: Among very old adults, the mean BMI and prevalence of obesity seemed to increase between 2000-2002 and 2015-2017. Meanwhile, the nutritional status (according to MNA scores) seemed to improve between 2000-2002 and 2010-2012, it declined by 2015-2017.

Severe orthostatic hypotension in a diabetic patient may not be due to diabetic autonomic neuropathy.

This lesson describes an unusual case of a man who was recently diagnosed with type 1 diabetes and who presented with severe orthostatic hypotension. As his diabetes was recent in onset, well controlled, and he had no other signs of microvascular disease, other causes of orthostatic hypotension were sought. His serum and cerebrospinal fluid were strongly positive for Borrelia burgdorferi IgG, suggesting a diagnosis of Lyme neuroborreliosis. Autonomic instability in Lyme, while rare, has been previously reported.

Tuberculosis and latent tuberculous infection screening of migrants in Europe: comparative analysis of policies, surveillance systems and results.

Migration patterns into and within Europe have changed over the last decade. In 2015, European Union (EU) countries received over 1.2 million asylum requests, more than double the number registered in the previous year. This review compares the published literature on policies for tuberculosis (TB) and latent tuberculous infection (LTBI) screening in EU and European Free Trade Association (EFTA) countries with the existing TB/LTBI screening programmes for migrants in 11 EU/EFTA countries based on a survey of policy and surveillance systems. In addition, we provide a systematic review of the literature on the yield of screening migrants for active TB and LTBI in Europe. Published studies provide limited information about screening coverage and the yield of screening evaluations in EU/EFTA countries. Furthermore, countries use different screening strategies and settings, and different definitions for coverage and yield of screening for active TB and LTBI. We recommend harmonising case definitions, reporting standards and policies for TB/LTBI screening. To achieve TB elimination targets, a European platform for multi-country data collection and analysis, sharing of countries' policies and practices, and harmonisation of migrant screening strategies is needed.

Body mass index, Mini Nutritional Assessment, and their association with five-year mortality in very old people.

OBJECTIVES: to investigate the prevalence of malnutrition and the association between Body Mass Index (BMI), Mini Nutritional Assessment (MNA) and five-year mortality in a representative population of very old (>85 years) people. DESIGN: A prospective cohort study. SETTING: A population-based study of very old people in northern Sweden and western Finland, living in institutional care or in the community. PARTICIPANTS: Out of 1195 potential participants, 832 were included (mean age 90.2±4.6 years). MEASUREMENTS: Nutritional status was assessed using BMI and MNA and the association of those two variables with five-year mortality was analyzed. RESULTS: The mean BMI value for the whole population was 25.1±4.5 kg/m2, with no difference between genders (P=0.938). The mean MNA score was 22.5±4.6 for the whole sample, and it was lower for women than for men (P<0.001). Thirteen percent were malnourished (MNA<17) and 40.3% at risk of malnutrition (MNA 17-23.5) according to MNA. Also, 34.8% of those with a MNA score <17 still had a BMI value ≥22.2 kg/m2. A BMI value <22.2 kg/m2 and a MNA score<17 were associated with lower survival. The association with mortality seemed to be J-shaped for BMI, and linear for MNA. CONCLUSIONS: Malnutrition according to MNA was common, but a substantial portion of those with a low MNA score still had a high BMI value, and vice versa. The association with mortality appeared to be J-shaped for BMI, and linear for MNA. The MNA seems to be a good measurement of malnutrition in very old people, and BMI might be misleading and could underestimate the prevalence of malnutrition, especially in women.

1,4-Cyclohexanecarboxylates: potent and selective inhibitors of phosophodiesterase 4 for the treatment of asthma.

Evaluation of a variety of PDE4 inhibitors in a series of cellular and in vivo assays suggested a strategy to improve the therapeutic index of PDE4 inhibitors by increasing their selectivity for the ability to inhibit PDE4 catalytic activity versus the ability to compete for high affinity [3H]rolipram-binding sites in the central nervous system. Use of this strategy led ultimately to the identification of cis-4-cyano-4-[3-(cyclopentyloxy)-4-methoxyphenyl]cyclohexane-1-carboxyl ic acid (1, SB 207499, Ariflo), a potent second-generation inhibitor of PDE4 with a decreased potential for side effects versus the archetypic first generation inhibitor, (R)-rolipram.

Suppression of human inflammatory cell function by subtype-selective PDE4 inhibitors correlates with inhibition of PDE4A and PDE4B.

1. Of the four major phosphodiesterase 4 (PDE4) subtypes, PDE4A, PDE4B and PDE4D are widely expressed in human inflammatory cells, including monocytes and T lymphocytes. We explored the functional role of these subtypes using ten subtype-selective PDE4 inhibitors, each belonging to one of two classes: (i) dual PDE4A/PDE4B inhibitors or (ii) PDE4D inhibitors. 2. These compounds were evaluated for their ability to inhibit antigen-stimulated T-cell proliferation and bacterial lipopolysaccharide (LPS)-stimulated tumour necrosis factor alpha (TNFalpha) release from peripheral blood monocytes. 3. All compounds inhibited T-cell proliferation in a concentration-dependent manner; with IC50 values distributed over an approximately 50 fold range. These compounds also inhibited TNFalpha release concentration-dependently, with a wider ( approximately 1000 fold) range of IC50 values. 4. In both sets of experiments, mean IC50 values were significantly correlated with compound potency against the catalytic activity of recombinant human PDE4A or PDE4B when analysed by either linear regression of log IC50 values or by Spearman's rank-order correlation. The correlation between inhibition of inflammatory cell function and inhibition of recombinant PDE4D catalytic activity was not significant in either analysis. 5. These results suggest that PDE4A and/or PDE4B may play the major role in regulating these two inflammatory cell functions but do not rule out PDE4D as an important mediator of other activities in mononuclear leukocytes and other immune and inflammatory cells. Much more work is needed to establish the functional roles of the PDE4 subtypes across a broader range of cellular functions and cell types.

Association of the anti-inflammatory activity of phosphodiesterase 4 (PDE4) inhibitors with either inhibition of PDE4 catalytic activity or competition for [3H]rolipram binding.

Phosphodiesterase 4 (PDE4) inhibitors are novel anti-inflammatory compounds. Unfortunately, the archetypal PDE4 inhibitor rolipram produces central nervous system and gastrointestinal side-effects. To exploit these agents, we need to identify PDE4 inhibitors that retain the anti-inflammatory activity with a reduced potential to elicit unwanted side-effects. PDE4 possesses both cyclic AMP catalytic activity that is inhibitable by rolipram and a high affinity binding site for rolipram. The function of this high affinity rolipram binding site is unclear; however, certain pharmacological effects of PDE4 inhibitors are associated with competition for this site. Since PDE4 inhibitors suppress both monocyte and neutrophil activation, the present experiments were carried out to establish a correlation between suppression of monocyte activation [tumor necrosis factor alpha (TNF alpha) formation] or suppression of neutrophil activation (degranulation) with inhibition of either PDE4 catalytic activity or [3H] rolipram binding. Suppression of TNF alpha formation demonstrated a strong correlation with inhibition of PDE4 catalytic activity (r=0.87; P<0.01; Spearman's Rho = 0.79, P<0.05), whereas there was no correlation with inhibition of [3H]rolipram binding(r=0.21, P>0.5; Spearman's Rho=0.16, P>0.5). Suppression of neutrophil degranulation was not associated with inhibition of PDE4 catalytic activity (r=0.25, P>0.4; Spearman's Rho=0.33, P>0.2), but was associated with inhibition of [3H]rolipram binding (r=0.68, P<0.05; Spearman's Rho=0.6, P=0.06). These results indicate that anti-inflammatory effects of PDE4 inhibitors can be associated with either inhibition of PDE4 catalytic activity or high affinity rolipram binding.

Desensitization of LLC-PK1 cells by vasopressin results in receptor down-regulation.

The molecular mechanism of desensitization of antidiuretic hormone receptors is not well understood. Preincubation of LLC-PK1 cells with lysine vasopressin (LVP) (10(-6) M, 5 h) decreased subsequent LVP-stimulated cAMP accumulation in cells by 83% and reduced the Vmax of LVP-stimulated adenylate cyclase by 81%. Such preincubation also reduced by 90% the binding of [3H]LVP to both intact cells and isolated plasma membranes, suggesting a loss of vasopressin receptors. Both the reduction in cAMP response and the apparent loss of receptors showed similar dose and time dependence. Monensin (33 microM) did not alter [3H]LVP binding or stimulation of cAMP by LVP, nor did it prevent desensitization. However, membranes prepared from cells preincubated with LVP in the presence of monensin did not show a decrease in [3H]LVP binding. Forskolin preincubation, at 0.1, 1, 10 and 100 microM, did not alter [3H]LVP binding or accumulation of cellular cAMP by LVP, nor did it induce desensitization to LVP. Cells desensitized with varying LVP concentrations in the presence of 10 microM forskolin displayed the same loss of [3H]LVP binding and LVP responsiveness as observed in the absence of forskolin. LVP-desensitized cells, upon removal from LVP-containing medium, recovered cAMP responsiveness to LVP and specific binding of [3H]LVP at the same rate, achieving control levels after 50 h. Recovery was prevented by cycloheximide (25 micrograms/ml). These findings are consistent with a desensitization process involving LVP-mediated receptor internalization, and a recovery process requiring protein synthesis.

Binge drinking among female Veterans Affairs patients: prevalence and associated risks.

This study evaluated the prevalence and associated risks of binge drinking, defined as having > or = 4 drinks on an occasion in the past year, in a female patient population. Of 1,259 female Veterans Affairs patients surveyed, 780 reported drinking alcohol in the past year, and 305 (24% of respondents, 39% of drinkers) reported binge drinking in the past year; 84 (11% of drinkers) had done so monthly or more often. Age-adjusted logistic regression analyses indicated that women who reported past-year binge drinking monthly or more often reported significantly increased odds of morning drinking (odds ratio [OR] = 40.3), others worrying about their drinking (OR = 38.6), arguments after drinking (OR = 13.5), hepatitis or cirrhosis (OR = 3.1), frequent injuries (OR = 2.6), smoking (OR = 3.7), drug use (OR = 22.2), and multiple sexual partners (OR = 4.6).

Concerns of rural men and women experiencing cancer.

PURPOSE/OBJECTIVES: To examine the interpersonal relationships, self-image, healthcare interactions, and occupational concerns of rural men and women experiencing cancer directly or as a caregiver of a person with cancer. DESIGN: A descriptive design employing a mail survey as part of a larger, longitudinal study. SETTING: Rural areas in the northern Rocky Mountain region of the United States. SAMPLE: 294 people with cancer and 294 family caregivers in Montana responded to mail questionnaires. Fifty-two percent were women, and almost all were Caucasian. METHODS: Investigator-developed Cancer Concerns Inventory mailed to participants. MAIN RESEARCH VARIABLES: Interpersonal relationships, self-image, healthcare interactions, occupational concerns, gender, and type of experience with cancer. FINDINGS: In general, women were more likely than men to report relationship problems, lack of support, and feelings that were not understood. People with cancer, as compared with caregivers, were more likely to report feeling alone and that other people avoided them and were afraid to talk to them. Men with cancer were more likely than women with cancer and caregivers to feel that their job security was threatened. However, only a small percentage of all participants felt discriminated against at work. In general, a higher percentage of women with cancer and men caregivers reported concerns about healthcare interactions than men with cancer and women caregivers. CONCLUSIONS: Men and women caregivers and people with cancer have different concerns regarding cancer. IMPLICATIONS FOR NURSING PRACTICE: Nurses working in rural areas must help families work through relationship difficulties, maximize healthcare interactions, and be an advocate for people with cancer.

A qualitative study of self-transcendence in caregivers of terminally ill patients.

Despite changes in social and cultural structure, the family has remained a consistent provider of in-home care needs for the chronically and terminally ill. The experience of a terminal illness is not limited to the individual patient and creates a myriad of challenges for the family, including the struggle to adjust and respond to the demands of the situation. The purpose of this study was to assess the caregivers' sense of emotional well being and their ability to transcend and find meaning in the caregiving experience. The participants in this study were all caregivers of a family member who had died six to 12 months prior to the interview. They were able to find meaning as a result of their caregiving experience within the context of supportive networks, caregiving actions, grief and loss, fatigue, financial burdens and multiple challenges. Finding meaning involved "being with" or "doing for" their loved one as death approached. Finding meaning had positive consequences for the caregivers. They described a new life view and were able to reach out to help others as a result of their caregiving.

Childhood primary care services in Wyoming.

Provision of childhood primary care services and differences between types of providers (family practice physicians, pediatricians, nurse practitioners, and physicians' assistants) were explored in this study. A mail survey was conducted in Wyoming using a questionnaire based on the recommendations from the U.S. Preventive Service Task Force. Sixty-one percent of the providers returned questionnaires. While some areas of assessment, screening, and treatment/counseling services were provided at high levels, many were not. Gaps exist particularly in the areas of behavioral and lifestyle assessment and treatment/counseling. Only small differences existed between types of providers. However, nurse practitioners and pediatricians were more likely to report that they followed recommendations, while physicians' assistants were least likely to report that they followed recommendations.

Rural nurse practitioners: perceptions of ethical dilemmas.

The purposes of this study were to identify ethical dilemmas encountered by rural nurse practitioners in primary practice and to identify constraints or enhancers that influenced ethical decision making. Nine nurse practitioners from Wyoming and Colorado responded to in-depth interviews. Six categories of ethical dilemmas and a list of constraints and enhancers were identified. One central concept, conflict between personal values and professional responsibility, emerged. Beneficence, nonmaleficence, justice, and patient autonomy, as core ethical principles, were related to this central conflict.

Family caregiver expectations and management of the stroke trajectory.

Less than 20% of stroke survivors enter rehabilitation or long-term care facilities after their stroke. Stroke recovery is extremely variable and the resulting uncertainty places a heavy burden on the survivors' family caregivers. According to the trajectory framework, chronic conditions have a defined course that can be shaped and managed. This grounded theory study, part of a larger research project, explored the expectations of family caregivers of the stroke trajectory and their management strategies. Thirteen family caregivers of stroke patients in a sparsely populated area participated in semi-structured interviews. The caregivers were without ideas about what the recovery of their loved ones would be like and had difficulty making projections about the trajectory. They used several strategies, however, in attempts to manage the stroke trajectory. They constructed a positive recovery, reconstituted family life, maintained family routines, created a safety net, and redoubled self-reliance. The findings have implications for how nurses support family caregivers of stroke survivors.

Informational needs of caregivers of terminal patients in a rural state.

Home care of a terminally ill family member is stressful, especially in rural areas. This qualitative study sought to determine informational needs of rural caregivers and how that information is obtained. Although most caregivers stated satisfaction with available information, mostly obtained from physicians and nurses, their behavior belied their satisfaction. Assertive and self-reliant, they used informal communications rather than written information to meet most of their needs. Approaches home care nurses can use to help caregivers obtain important information are presented.
