Cost-effectiveness of CI in developing countries

Purpose of review Cost-effectiveness of cochlear implants is a major concern for expanding these services to low-income and middle-income developing countries. Recent findings Recent studies have applied appropriate methodology to make determination of cost-effectiveness for cochlear implants in developing countries. In addition, important parameters that effect cost-effectiveness have been reviewed in a systematic way. The combination of these new studies along with existing reports of cochlear implant programmes in developing countries allows for a discussion of cost and outcomes determinants that drive cost-effectiveness in these environments. Summary Cochlear implants are a very cost-effective treatment for profound hearing loss in all high-resource countries and in many low-income and middle-income developing countries. A number of cost considerations affect cost-effectiveness of cochlear implants in developing countries including device cost and device-related expenses such as power consumption and reliability, but also including rehabilitation and access-related expenses. Large-scale programmes confer an advantage for cost-effectiveness, primarily through device-related savings.

In case you missed it – basic science advances in Transplantation 2017

Developments in organ preservation techniques, novel immunosuppressants and improved diagnostics have made organ transplantation the success it is today. That does not mean that we are not still striving to perfect techniques, or that there are no more problems to solve. New strategies to address the donor organ shortage, prevent and manage antibody-mediated rejection, lower long-term allograft failure rates and reduce the toxicity of life-long immunosuppressive medication are urgently needed, and are being widely researched. Both fundamental research and preclinical studies aim to solve these problems and, ultimately, benefit organ transplant recipients. This article highlights the latest technical developments and trends in xenotransplantation, tissue injury and regeneration, immunosuppression, and transplantation immunology described in the most viewed and cited papers published in the Basic Sciences section of the Transplantation journal during the year 2017.

Defining Outcomes for β-Cell Replacement Therapy in the Treatment of Diabetes: a Consensus Report on the Igls Criteria from the IPITA/EPITA Opinion Leaders Workshop

β-cell replacement therapy, available currently as pancreas or islet transplantation, has developed without a clear definition of graft functional and clinical outcomes. The International Pancreas & Islet Transplant Association (IPITA) and European Pancreas & Islet Transplantation Association (EPITA) held a workshop to develop consensus for an IPITA/EPITA Statement on the definition of function and failure of current and future forms of β-cell replacement therapy. There was consensus that β-cell replacement therapy could be considered as a treatment for β-cell failure, regardless of etiology and without requiring undetectable C-peptide, accompanied by glycemic instability with either problematic hypoglycemia or hyperglycemia. Glycemic control should be assessed at a minimum by glycated hemoglobin (HbA1c) and the occurrence of severe hypoglycemia. Optimal β-cell graft function is defined by near-normal glycemic control (HbA1c ≤6.5% [48 mmol/mol]) without severe hypoglycemia or requirement for insulin or other antihyperglycemic therapy, and with an increase over pretransplant measurement of C-peptide. Good β-cell graft function requires HbA1c 50%) reduction in insulin requirements and restoration of clinically significant C-peptide production. Marginal β-cell graft function is defined by failure to achieve HbA1c

The effect of pregnancy on the long-term risk of graft loss, cardiovascular disease and death in kidney transplanted women in Norway: a retrospective cohort study

ABSTRACTBackgroundKidney transplant recipients have now conceived for almost 50 years. Nevertheless, few studies have evaluated long-term health outcomes for kidney transplanted women following pregnancies.MethodsWe conducted a retrospective cohort study of all Norwegian women receiving a kidney transplant before the age of 50 years between 1969 and 2013, with graft loss, cardiovascular disease and death as outcomes. Baseline characteristics for all women were ascertained at first transplantation, with information about exposure, outcomes and potential confounders collected from medical records. To account for changes in pregnancy status, data were analyzed using proportional hazard Cox regression with pregnancy status as a time-dependent covariate changing at the time of pregnancy.ResultsOf 650 women studied, 124 had a pregnancy following kidney transplantation. During the study period graft loss, cardiovascular disease and death occurred in 237, 73 and 274 women, respectively. Pregnancy was associated with 54% lower risk of graft loss (95% confidence interval [CI]: 25% to 71%) and 72% lower risk of death (95% CI: 53% to 84%). Adjusting for possible confounders had a minimal impact on estimated values. There were considerable uncertainties and no statistically significant results regarding the estimated risk of cardiovascular disease following pregnancy (univariate hazard ratio; 0.91, 95% CI: 0.43 to 1.92, multivariate hazard ratio; 0.71, 95% CI: 0.32 to 1.60).ConclusionsKidney transplanted women with pregnancies have a low risk of subsequent graft loss or death. These results are reassuring for the current clinical practice. Background Kidney transplant recipients have now conceived for almost 50 years.

Novel compound heterozygous mutations in KREMEN1 confirm it as a disease gene for ectodermal dysplasia

Abstract

Ectodermal dysplasia (ED) is a heterogeneous group of disorders caused by mutations in at least thirteen genes. Recently, a study reported Palestinian patients with ED from consanguineous families with a homozygous mutation in KREMEN1 (Kringle-containing transmembrane protein 1) and proposed it to be a causative gene for the autosomal recessive ED 13, hair/tooth type (ECTD13; OMIM #617392). A Thai family, parents and two children affected with ED, was recruited. The study was exempted from review by the Institutional Review Board, Faculty of Medicine, Chulalongkorn University (IRB584/60). Written informed consents of each participant were obtained according to the Declaration of Helsinki. Mutation analyses were performed as described previously.

Pulmonary function in subjects with psoriasis: A cross-sectional population study

Abstract

Psoriasis is a prevalent chronic inflammatory disease associated with comorbidities, e.g. cardiometabolic diseases, inflammatory bowel disease, and depression that may share an inflammatory origin. Smoking increases the risk of psoriasis and the disease has also been linked to chronic obstructive pulmonary disease (COPD) and asthma, with evidence of shared inflammatory cytokine-mediated mechanisms. Moreover, subjects with psoriasis display increased risk of infections, especially respiratory infections including pneumonia. However, only a small single-center study of pulmonary function in subjects with psoriasis is available.

Recurrent erysipelas of the face with hyperimmune reaction to group C streptococcus

Abstract

We present the case of a 73-year-old-woman, admitted in 2014 for n erysipelas of the face (figure 1a) beginning 3 days before, with red oedematous papules of the left temple, hyperthermia and chills the day after. Clinical examination did not find lymphadenopathy or skin lesion especially at her left ear. Blood samples showed a raised C reactive protein (CRP) to 120 mg/L without leukocytosis. Antinuclear antibodies were negative. Viral serologies (HIV, hepatitis C and B, EBV, parvovirus B19, VZV, mumps), viral PCR assay (EBV, parvovirus B19, CMV, VZV) and bacterial blood cultures were all negative Histopathological findings revealed a reactive infiltrate without vasculitis and necrosis.

Differential blood cellular profile in patients with moderate to severe psoriasis treated with classical systemic therapies: A step forward in personalised medicine

Abstract

patients with moderate to severe psoriasis are difficult to treat with topical therapy only and they usually require additional systemic therapy. Despite this, a significant percentage of patients on these therapies shows an inadequate response to these drugs. Treatment decisions are often difficult as they usually rely on subjective terms. Therefore, finding indicators that predict efectiveness or failure to classical systemic therapy is an urgent need. The objective of this study was to analyse whether the phenotype of peripheral blood mononuclear cells (PBMC) would be different in responder or non-responder patients to classical systemic therapy, and thus could be used as a efectiveness predictor of this therapy effectiveness. These predictor markers could help physicians to choose the best individualised treatment for psoriasis patients.

Cutaneous squamous cell carcinomas are associated with basal proliferating actinic keratoses

Abstract

Background

In addition to the extent of atypical keratinocytes throughout the epidermis, actinic keratoses (AKs) are histologically characterized by downward directed basal layer expansion. It is not known if this growth pattern correlates with the risk of developing invasive squamous cell carcinoma (iSCC).

Objective

To characterize the prevalence of downward directed basal layer expansion of AKs adjacent to iSCC.

Methods

The epidermis overlying and adjacent to iSCCs was assessed histologically. We determined the histological grade (AKI-III), basal growth pattern (PROI-III) and accompanying parameters such as adnexal involvement.

Results

Of 307 lesions, 52.4% of AKs were histologically classified as AKI, 38.1% as AKII, and 6.8% as AKIII (chi-squared; P<0.0001). 2.6% of adjacent epidermis did not show any atypical keratinocytes. The epidermis adjacent to iSCCs was classified as having a PROI basal growth pattern in 25.7%, PROII in 31.9%, and PROIII in 39.4% cases. 2.9% of AKs showed no basal growth (chi-squared; P<0.0001).118 (48.8%) AKs showed extension into adnexal structures. These AKs were graded as PROI in 18.6%, PROII in 30.5%, and PROIII in 50.8%. The epidermis above iSCCs could only be assessed for upwards directed growth and showed no significant differences in the three AK grades (P=0.4211).

Conclusions

Basal proliferative AKs as well as atypical keratinocytes restricted to the lower third of the epidermis are most commonly seen adjacent to iSCC with less evidence for full thickness epidermal dysplasia. Our study supports the important role of dysplastic keratinocytes in the epidermal basal layer and their potential association with iSCC.

Population-based prevalence of Eosinophilic (Shulman's) Fasciitis: a capture-recapture study

Abstract

Our knowledge of Eosinophilic fasciitis (EF), also known as Shulman's syndrome, is limited, and its prevalence has not been estimated so far. We conducted a regional survey which aimed at estimating the prevalence of EF in Alsace, a Region in the North-East of France. We retrospectively collected EF cases from the first of January 1983 to the 30th of March 2015 among Alsace residents aged >18 years, then performed a capture-recapture analysis with the prevalent cases in 2015.

Effects of personal air pollution exposure on asthma symptoms, lung function and airway inflammation

Abstract

Background

There is evidence that air pollution increases the risk of asthma hospitalisations and healthcare utilisation, but the effects on day-to-day asthma control are not fully understood.

Objective

We undertook a prospective single-centre panel study to test the hypothesis that personal air pollution exposure is associated with asthma symptoms, lung function and airway inflammation.

Methods

Thirty-two patients with a clinical diagnosis of asthma were provided with a personal air pollution monitor (Cairclip NO2/O3) which was kept on or around their person throughout the 12-week follow-up period. Ambient levels of NO2 and particulate matter were modelled based upon satellite imaging data. Directly measured ozone, NO2 and particulate matter levels were obtained from a monitoring station in central Leicester. Participants made daily electronic records of asthma symptoms, peak expiratory flow, and exhaled nitric oxide. Spirometry and asthma symptom questionnaires were completed at fortnightly study visits. Data were analysed using linear mixed effects models and cross-correlation.

Results

Cairclip exposure data were of good quality with clear evidence of diurnal variability and a missing data rate of approximately 20%. We were unable to detect consistent relationships between personal air pollution exposure and clinical outcomes in the group as a whole. In an exploratory subgroup analysis, total oxidant exposure was associated with increased daytime symptoms in women but not men.

Conclusions and clinical relevance

We did not find compelling evidence that air pollution exposure impacts on day-to-day clinical control in an unselected asthma population, but further studies are required in larger populations with higher exposure levels. Women may be more susceptible than men to the effects of air pollution, an observation which requires confirmation in future studies.
