Independent associations of TOMM40 and APOE variants with body mass index

The TOMM40-APOE variants are known for their strong, antagonistic associations with Alzheimer's disease and body weight. While a stronger role of the APOE than TOMM40 variants in Alzheimer's disease was suggested, comparative contribution of the TOMM40-APOE variants in the regulation of body weight remains elusive. We examined additive effects of rs2075650 and rs157580 TOMM40 variants and rs429358 and rs7412 APOE variants coding the ε2/ε3/ε4 polymorphism on body mass index (BMI) in age-aggregated and age-stratified cohort-specific and cohort-pooled analysis of 27,863 Caucasians aged 20–100 years from seven longitudinal studies. Minor alleles of rs2075650, rs429358, and rs7412 were individually associated with BMI (β = −1.29, p = 3.97 × 10−9; β = −1.38, p = 2.78 × 10−10; and β = 0.58, p = 3.04 × 10−2, respectively). Conditional analysis with rs2075650 and rs429358 identified independent BMI-lowering associations for minor alleles (β = −0.63, p = 3.99 × 10−2 and β = −0.94, p = 2.17 × 10−3, respectively). Polygenic mega-analysis identified additive effects of the rs2075650 and rs429358 heterozygotes (β = −1.68, p = 3.00 × 10−9), and the strongest BMI-lowering association for the rs2075650 heterozygous and rs429358 minor allele homozygous carriers (β = −4.11, p = 2.78 × 10−3). Conditional analysis with four polymorphisms identified independent BMI-lowering (rs2075650, rs157580, and rs429358) and BMI-increasing (rs7412) associations of heterozygous genotypes with BMI. Age-stratified conditional analysis revealed well-powered support for a differential and independent association of the rs429358 heterozygote with BMI in younger and older individuals, β = 0.58, 95% confidence interval (CI) = −1.18, 2.35, p = 5.18 × 10−1 for 3,068 individuals aged ≤30 years and β = −4.28, CI = −5.65, −2.92, p = 7.71 × 10−10 for 6,052 individuals aged &gt;80 years. TOMM40 and APOE variants are independently and additively associated with BMI. The APOE ε4-coding rs429358 polymorphism is associated with BMI in older individuals but not in younger individuals.</p

Hospital Costs of Extracorporeal Membrane Oxygenation in Adults: A Systematic Review

Background: Costs associated with extracorporeal membrane oxygenation (ECMO) are an important factor in establishing cost effectiveness. In this systematic review, we aimed to determine the total hospital costs of ECMO for adults. Methods: The literature was retrieved from the PubMed/MEDLINE, EMBASE, and Web of Science databases from inception to 4 March 2020 using the search terms ‘extracorporeal membrane oxygenation’ combined with ‘costs’; similar terms or phrases were then added to the search, i.e. ‘Extracorporeal Life Support’ or ‘ECMO’ or ‘ECLS’ combined with ‘costs’. We included any type of study (e.g. randomized trial or observational cohort) evaluating hospital costs of ECMO in adults (age ≥18 years). Results: A total of 1768 unique articles were retrieved during our search. We assessed 74 full-text articles for eligibility, of which 14 articles were selected for inclusion in this review; six papers were from the US, five were from Europe, and one each from Japan, Australia, and Taiwan. The sample sizes ranged from 16 to 18,684 patients. One paper exclusively used prospective cost data collection, while all other papers used retrospective data collection. Five papers reported charges instead of costs. There was large variation in hospital costs, ranging from US$22,305 to US$334,608 (2019 values), largely depending on the indication for ECMO support and location. The highest reported costs were for lung transplant recipients who were receiving ECMO support in the US, and the lowest reported costs were for extracorporeal cardiopulmonary resuscitation patients presenting with non-shockable rhythm in Japan. The additional costs of ECMO patients compared with non-ECMO patients varied between US$2518 and US$200,658. Personnel costs varied between 11 and 52% of the total amount. Conclusions: ECMO therapy is an advanced and expensive technology, although reported costs differ considerably depending on ECMO indication and whether charges or costs are measured. Combined with the ongoing gathering of outcome data, cost effectiveness per ECMO indication could be determined in the future

Majority of females with a life-long experience of CAH and parents do not consider females with CAH to be intersex

Introduction To assess opinions of females with CAH, and parents of females with CAH, about designating this population “intersex,” particularly in legislation about genital surgery during childhood. Methods We conducted a mixed-methods (quantitative and qualitative) anonymous cross-sectional online survey of females with CAH (46XX, 16+years old) and independently recruited parents of girls with CAH (2019–2020) diagnosed in first year of life from the United States. A multidisciplinary CAH team drafted the survey in collaboration with women with CAH and parents. Fisher's exact test was used to compare female and parent responses. A qualitative thematic approach was used to analyze open-ended answers for emergent categories of reasons why CAH females should or should not be considered as intersex. Results Of 57 females with CAH participating (median age: 39 years, 75.5% of ≥25year olds had post-secondary degree), all had classical CAH and 93.0% underwent genital surgery at median 1–2 years old. While 89.5% did not endorse the intersex designation for CAH, the remaining 5.3% did (5.3% provided no answer, Summary Figure). Most CAH females (63.2%) believed CAH females should be considered separately in “any laws banning or allowing surgery of children's genitals” (19.3% disagreed, 17.5% neutral, 0.0% no answer). Most common themes identified by females with CAH not endorsing an intersex designation were: normal female internal organs, sex chromosomes, personal identity, genital appearance, issues with language, hormones, and those endorsing it: genital appearance, community/group experiences, topic complexity. Overall, 132 parents of females with CAH participated (parent/child median ages: 40/11 years, 81.7% of ≥25year olds had post-secondary degree). All children had classical CAH and 78.8% underwent surgery at median <1 year old. While 95.5% of parents did not endorse the intersex designation for CAH, 2.3% did (2.3% no answer), similar to females (p = 0.29). Most parents (81.1%) believed CAH females should be considered separately in legislation (9.1% disagreed, 6.1% neutral, 3.8% no answer), a slightly higher percentage than females (p = 0.01). Discussion Echoing previously published disagreement with clinically designating CAH females as intersex, majority of CAH females and parents oppose a legal intersex designation. Differing opinions among females and parents strengthen concern about a one-size-fits-all approach to legislation about childhood genital surgery. Differences in opinions between female and parent responses, while statistically significant, were relatively small. Conclusion: Majority of females with CAH and their parents believe CAH should be excluded from the intersex designation and be considered separately in legislation pertaining to childhood genital surgery in childhood

Nutrition support in cancer patients: a brief review and suggestion for standard indications criteria

The indications of nutrition support in cancer patients have been subject to controversy. Most studies address the effects of the method in increasing the survival or the tumor response rate. Few studies have focused on the effects in improving quality of life. After a brief review, we described the results of a study, which evaluated the effects of protein-caloric supplementation on the quality of life parameters in a group of head and neck cancer patients submitted to radiotherapy. The results support the suggestion of creating standard criteria to indicate nutrition support in cancer patients. Based on our findings, nutrition support should be indicated for cancer patients considering the potential effects to improve the quality of life

Prognostic Efficacy of the Albumin Grade in Patients with Hepatocellular Carcinoma

We previously found that “albumin grade”, formerly called the “ALBS grade,” demonstrated significant capability for prognostic stratification in hepatocellular carcinoma (HCC) patients treated with lenvatinib. The purpose of the present study was to compare the performance of the albumin grade with that of the modified albumin-bilirubin (mALBI) grade in predicting overall survival of HCC patients with different BCLC stages and treatment types. We enrolled 7,645 Japanese patients newly diagnosed with HCC using the Akaike information criteria (AIC), likelihood ratio, and C-index in different Barcelona Clinic Liver Cancer (BCLC) stages and treatments. The albumin grade showed similar and slightly better performance than the mALBI grade for BCLC stage 0 and A and especially for patients who underwent curative surgery and ablation. In patients treated with transcatheter arterial chemoembolization, molecular targeted agents, and the best supportive care, the mALBI grade had better performance than the albumin grade. However, the differences of the indices were very small in all scenarios. Overall, the albumin grade was comparable in efficacy to the mALBI grade, showing particular benefit for patients with early-stage HCC

Comparative effectiveness of antihypertensive medication for primary prevention of cardiovascular disease: systematic review and multiple treatments meta-analysis

Background: We conducted a systematic review of evidence from randomized controlled trials to answer the following research question: What are the relative effects of different classes of antihypertensive drugs in reducing the incidence of cardiovascular disease outcomes for healthy people at risk of cardiovascular disease? Methods: We searched MEDLINE, EMBASE, AMED (up to February 2011) and CENTRAL (up to May 2009), and reference lists in recent systematic reviews. Titles and abstracts were assessed for relevance and those potentially fulfilling our inclusion criteria were then assessed in full text. Two reviewers made independent assessments at each step. We selected the following main outcomes: total mortality, myocardial infarction and stroke. We also report on angina, heart failure and incidence of diabetes. We conducted a multiple treatments meta-analysis using random-effects models. We assessed the quality of the evidence using the GRADE-instrument. Results: We included 25 trials. Overall, the results were mixed, with few significant dif-ferences, and with no drugclass standing out as superior across multiple outcomes. The only significant finding for total mortality based on moderate to high quality evidence was that beta-blockers (atenolol) were inferior to angiotensin receptor blockers (ARB) (relative risk (RR) 1.14; 95% credibility interval (CrI) 1.02 to 1.28). Angiotensin converting enzyme (ACE)- inhibitors came out inferior to calcium-channel blockers (CCB) regarding stroke-risk (RR 1.19; 1.03 to 1.38), but superior regarding risk of heart failure (RR 0.82; 0.69 to 0.94), both based on moderate quality evidence. Diuretics reduced the risk of myocardial infarction compared to beta-blockers (RR 0.82; 0.68 to 0.98), and lowered the risk of heart failure compared to CCB (RR 0.73; 0.62 to 0.84), beta-blockers (RR 0.73; 0.54 to 0.96), and alpha-blockers (RR 0.51; 0.40 to 0.64). The risk of diabetes increased with diuretics compared to ACE-inhibitors (RR 1.43; 1.12 to 1.83) and CCB (RR 1.27; 1.05 to 1.57). Conclusion: Based on the available evidence, there seems to be little or no difference between commonly used blood pressure lowering medications for primary prevention of cardiovascular disease. Beta-blockers (atenolol) and alpha-blockers may not be first-choice drugs as they were the only drug-classes that were not significantly superior to any other, for any outcomes
