Engaging Local Communities in Low Emissions Land-Use Planning: a Case Study from Laos

Reducing Emissions from Deforestation and Forest Degradation and enhancing forest carbon stocks (REDD+) is a performance-based payment mechanism currently being debated in international and national environmental policy and planning forums. As the mechanism is based on conditionality, payments must reflect land stewards’ level of compliance with carbon-efficient management practices. However, lack of clarity in land governance and carbon rights could undermine REDD+ implementation. Strategies are needed to avoid perverse incentives resulting from the commoditization of forest carbon stocks and, importantly, to identify and secure the rights of legitimate recipients of future REDD+ payments. We propose a landscape-level approach to address potential conflicts related to carbon tenure and REDD+ benefit sharing. We explore various land-tenure scenarios and their implications for carbon ownership in the context of a research site in northern Laos. Our case study shows that a combination of relevant scientific tools, knowledge, and participatory approaches can help avoid the marginalization of rural communities during the REDD+ process. The findings demonstrate that participatory land-use planning is an important step in ensuring that local communities are engaged in negotiating REDD+ schemes and that such negotiations are transparent. Local participation and agreements on land-use plans could provide a sound basis for developing efficient measurement, reporting, and verification systems for REDD+.

Acute coronary syndrome in patients younger than 30 years--aetiologies, baseline characteristics and long-term clinical outcome

BACKGROUND Coronary atherosclerosis begins early in life, but acute coronary syndromes in adults aged <30 years are exceptional. We aimed to investigate the rate of occurrence, clinical and angiographic characteristics, and long-term clinical outcome of acute coronary syndrome (ACS) in young patients who were referred to two Swiss hospitals. METHODS From 1994 to 2010, data on all patients with ACS aged <30 years were retrospectively retrieved from our database and the patients were contacted by phone or physician's visit. Baseline, lesion and procedural characteristics, and clinical outcome were compared between patients in whom an underlying atypical aetiology was found (non-ATS group; ATS: atherosclerosis) and patients in whom no such aetiology was detected (ATS group). The clinical endpoint was freedom from any major adverse cardiac event (MACE) during follow-up. RESULTS A total of 27 young patients with ACS aged <30 years were admitted during the study period. They accounted for 0.05% of all coronary angiograms performed. Mean patient age was 26.8 ± 3.5 years and 22 patients (81%) were men. Current smoking (81%) and dyslipidaemia (59%) were the most frequent risk factors. Typical chest pain (n = 23; 85%) and ST-segment elevation myocardial infarction (STEMI; n = 18 [67%]) were most often found. The ATS group consisted of 17 patients (63%) and the non-ATS group of 10 patients (37%). Hereditary thrombophilia was the most frequently encountered atypical aetiology (n = 4; 15%). At 5 years, mortality and MACE rate were 7% and 19%, respectively. CONCLUSION ACS in young patients is an uncommon condition with a variety of possible aetiologies and distinct risk factors. In-hospital and 5-year clinical outcome is satisfactory.

A unified nomenclature of NITRATE TRANSPORTER 1/PEPTIDE TRANSPORTER family members in plants

Members of the plant NITRATE TRANSPORTER 1/PEPTIDE TRANSPORTER (NRT1/PTR) family display protein sequence homology with the SLC15/PepT/PTR/POT family of peptide transporters in animals. In comparison to their animal and bacterial counterparts, these plant proteins transport a wide variety of substrates: nitrate, peptides, amino acids, dicarboxylates, glucosinolates, IAA, and ABA. The phylogenetic relationship of the members of the NRT1/PTR family in 31 fully sequenced plant genomes allowed the identification of unambiguous clades, defining eight subfamilies. The phylogenetic tree was used to determine a unified nomenclature of this family named NPF, for NRT1/PTR FAMILY. We propose that the members should be named accordingly: NPFX.Y, where X denotes the subfamily and Y the individual member within the species.

The channel-activating protease CAP1/Prss8 is required for placental labyrinth maturation

The serine protease CAP1/Prss8 is crucial for skin barrier function, lung alveolar fluid clearance and has been unveiled as diagnostic marker for specific cancer types. Here, we show that a constitutive knockout of CAP1/Prss8 leads to embryonic lethality. These embryos presented no specific defects, but it is during this period, and in particular at E13.5, that wildtype placentas show an increased expression of CAP1/Prss8, thus suggesting a placental defect in the knockout situation. The placentas of knockout embryos exhibited significantly reduced vascular development and incomplete cellular maturation. In contrary, epiblast-specific deletion of CAP1/Prss8 allowed development until birth. These CAP1/Prss8-deficient newborns presented abnormal epidermis, and died soon after birth due to impaired skin function. We thus conclude that a late placental insufficiency might be the primary cause of embryonic lethality in CAP1/Prss8 knockouts. This study highlights a novel and crucial role for CAP1/Prss8 in placental development and function.

„Offene Grenzen“ oder „freiwillige Ghetttoisierung“? Aktuelle Kontroversen um die Sicherung der Kontinuität des Judentums

Die jüdische Gemeinschaft gilt generell als Musterbeispiel einer gut integrierten, religiösen Minderheit. Tatsächlich jedoch bewirken gerade die jüngsten gesellschaftlichen Entwicklungen − verstärkte Säkularisierung und Individualisierung verbunden mit steigenden Mischehenraten und einer Neudefinitionder Geschlechterrollen − eine Infragestellung der Kontinuität europäisch-jüdischer Existenz.Seit den 70iger Jahren des 20. Jahrhunderts bewegt sich die Mischehenrate fast überall in der Diaspora bei über 50%. Da die Weitergabe des Judentums religionsgesetzlich nur über die Mutter erfolgt,stellt der Umgang mit nichtjüdischen Familienmitgliedern einen hochsensiblen Bereich für die Gemeinschaft dar. Die soziale und religiöse Integration von nichtjüdischen Ehefrauen und vaterjüdischenKindern ist auf Grund einer nicht selten willkürlich erscheinenden Aufnahmepraxis ein häufig tabuisierter Aspekt des Gemeindelebens, der zu permanenten Spannungen führt. Konflikte bezüglich der Zugehörigkeitskriterien aber auch der religiösen Rolle der Frau führen zu Polarisierungs- und Pluralisierungstendenzen. Im Rahmen eines Projektes des NFP 58 wurden aktuelle innerjüdische Grenzziehungsdebatten im Kontext des Schweizer Judentums auch mit Methoden der Oral History festgehalten und analysiert. Die Auseinandersetzungen innerhalb der schweizerisch-jüdischen Gemeinschaft wurden zudem mit Entwicklungen in anderen Ländern der Diaspora und in Israel verglichen. Es ergab sich das Bild einer dynamischen und zugleich jedoch tief gespaltenen Religionsgemeinschaft, innerhalb der sich die verschiedenen Richtungen („liberal“ bis „ultra-orthodox“) die Verantwortung für eine zunehmende Schwächung und Spaltung des jüdischen Volkes zuweisen.

Perfecting Imperfect Duties via Institutionalization

Onora O’Neill’s thesis that, in a world like ours, institutionalization is a necessary condition for the existence of typical universal welfare rights—the “institutionalization thesis” for short—has often been criticized. I believe that most of these criticisms fail to appreciate that the institutionalization thesis is based on her “classical” understanding of rights, which stresses the essential duty-implying character of rights. By and large, O’Neill’s thesis stands and falls with the classical theory of rights. My suggestion is, therefore, that what is really at issue between O’Neill and at least some of her critics is the proper understanding of the concept of a right.

Long-Term Comparison of Everolimus-Eluting and Biolimus-Eluting Stents in All-Comer Patients

AIMS: Second-generation everolimus-eluting stents (EES) are safer and more efficient than first-generation paclitaxel-eluting stents (PES). Third-generation biolimus-eluting stents (BES) have been found to be non-inferior to PES. To date, there is no available comparative study between EES and BES. We aimed to investigate the safety and efficacy of BES with biodegradable polymer compared to EES with durable polymer at a follow-up of two years in an unselected population of consecutively enrolled patients. METHODS AND RESULTS: A group of 814 consecutive patients undergoing percutaneous coronary intervention (PCI) was enrolled between 2007 and 2010, of which 527 were treated with EES and 287 with BES implantation. Clinical outcome was compared in 200 pairs using propensity score matching. The primary endpoint was a composite of death, myocardial infarction (MI) and target vessel revascularisation (TVR) at two-year follow-up. Median follow-up was 22 months. The primary outcome occurred in 11.5% of EES and 10.5% of BES patients (HR 1.11, 95% CI: 0.61-2.00, p=0.74). At two years, there was no significant difference with regard to death (HR 0.49, 95% CI: 0.18-1.34, p=0.17), cardiac death (HR 0.14, 95% CI: 0.02-1.14, p=0.66) or MI (HR 6.10, 95% CI: 0.73-50.9, p=0.10). Stent thrombosis (ST) incidence was evenly distributed between EES (n=2) and BES (n=2) (p-value=1.0). CONCLUSIONS: This first clinical study failed to demonstrate any significant difference regarding safety or efficacy between these two types and generations of drug-eluting stents (DES).

Comparison of everolimus- and biolimus-eluting stents with everolimus-eluting bioresorbable vascular scaffold stents: study protocol of the randomized controlled EVERBIO II

BACKGROUND: Second-generation everolimus-eluting stents (EES) and third generation biolimus-eluting stents (BES) have been shown to be superior to first-generation paclitaxel-eluting stents (PES) and second-generation sirolimus-eluting stents (SES). However, neointimal proliferation and very late stent thrombosis is still an unresolved issue of drug-eluting stent (DES) implantation overall. The Absorb™ (Abbott Vascular, Abbott Park, IL, USA) is the first CE approved DES with a bioresorbable vascular scaffold (BVS) thought to reduce long-term complication rates. The EVERBIO II trial was set up to compare the BVS safety and efficacy with both EES and BES in all patients viable for inclusion. METHODS/DESIGN: The EVERBIO II trial is a single-center, assessor-blinded, randomized trial. The study population consists of all patients aged≥18 years old undergoing percutaneous coronary intervention. Exclusion criterion is where the lesion cannot be treated with BVS (reference vessel diameter>4.0 mm). A total of 240 patients will be enrolled and randomly assigned into 3 groups of 80 with either BVS, EES or BES implantation. All patients will undergo a follow-up angiography study at 9 months. Clinical follow-up for up to 5 years will be conducted by telephone. The primary endpoint is in-segment late lumen loss at 9 months measured by quantitative coronary angiography. Secondary endpoints are patient-oriented major adverse cardiac event (MACE) (death, myocardial infarction and target-vessel revascularization), device-oriented MACE (cardiac death, myocardial infarction and target-lesion revascularization), stent thrombosis according to ARC and binary restenosis at follow-up 12 months angiography. DISCUSSION: EVERBIO II is an independent, randomized study, aiming to compare the clinical efficacy, angiographic outcomes and safety of BVS, EES and BES in all comer patients. TRIAL REGISTRATION: The trial listed in clinicaltrials.gov as NCT01711931.

Ten year clinical follow-up after Sirolimus-eluting stent implantation

BACKGROUND: Little is known on the "very" long-term incidence of major adverse cardiac events (MACE), target-lesion revascularization (TLR), target-vessel revascularization and stent thrombosis after sirolimus-eluting stent (SES) implantation. We present the first study to provide a 10-year clinical follow-up in an unselected patient population who underwent SES implantation. METHODS AND RESULTS: We ran a systematic 10-year clinical follow-up in a series of 200 consecutive patients treated with unrestricted SES implantation between April 2002 and April 2003 in two Swiss hospitals. Outcomes and follow-up were obtained in all 200 patients. The cumulative 10-year MACE rate was 47% with all-cause death of 20%, cardiac death of 9%, myocardial infarction of 7%, TLR and target-vessel revascularization of 8% and 11% respectively. Academic Research Consortium-defined "definite and probable" stent thrombosis-rate was 2.5%. TLR risk was maximal between 3 to 6 years. New lesion revascularization increased throughout the study period. CONCLUSION: Incidence of TLR was maximal 3 to 6 years after SES implantation and decreased thereafter. MACE and non-TLR revascularization rates steadily increased during the complete follow-up underlining the progression of coronary artery disease.

A propensity score-matched comparison between Cardia and Amplatzer PFO closure devices - insights from the SOLUTION registry (Swiss percutaneOus patent foramen ovale cLosUre in recurrent clinical events prevenTION)

Aims: To compare clinical outcome of Amplatzer PFO (APFO) to Cardia PFO (CPFO) occluder. Percutaneous patent foramen ovale (PFO) closure prevents stroke recurrence in stroke due to paradoxical embolism. Methods and results: The primary endpoint was a composite of stroke, TIA, or peripheral embolism at follow-up. The secondary endpoint was residual shunt. Outcome was compared among 934 (APFO: 712; CPFO: 222) patients, and in 297 propensity score-matched patients. The primary endpoint occurred in 29 patients (0.71/100 patient-years): four (2%) with the CPFO (0.31/100 patient-years), and 25 (4%) with the APFO (0.89/100 patient-years) (p=0.20). Residual shunt at six months was more frequent with the CPFO (31% versus 9%, p<0.001). No differences in residual shunts were seen at the last available echocardiographic follow-up (9±18 months): APFO 11%, CPFO 14%, p=0.22. Conclusions: This study suggests that PFO closure with APFO or CPFO is equally effective for the prevention of recurrent events. Residual shunt was more frequent at six months with CPFO, but was similar to APFO at later follow-up.

Five-year results of a randomised comparison of titanium-nitride-oxide-coated stents with zotarolimus-eluting stents for coronary revascularisation.

Aims: Stents with a passive coating of titanium-nitride-oxide (TiNO) have been compared with Endeavor® zotarolimus-eluting stents (E-ZES) with regard to the primary endpoint of in-stent late lumen loss at six to eight months. The objective of the present analysis was to compare the long-term outcomes of TiNO stents with E-ZES up to five years of clinical follow-up. Methods and results: A total of 302 patients had been randomly allocated to treatment with TiNO or E-ZES. Up to five years of follow-up, major adverse cardiac events (MACE), the composite of cardiac death, myocardial infarction, or clinically indicated target vessel revascularisation (TLR), were observed in 27.6% of patients treated with TiNO stents and 25.3% of patients treated with E-ZES (RR 1.13, 95% CI: 0.72-1.75, p=0.60), with the majority of events related to clinically indicated TVR (TiNO 21.7% versus E-ZES 20.7%, RR 1.10, 95% CI: 0.67-1.81). There were no differences with respect to individual events including cardiac death, myocardial infarction or stent thrombosis between the two treatment arms up to five years of follow-up. A majority of patients remained free from angina throughout the entire study duration (TiNO 77.3% versus E-ZES 76.1%, p=0.92). Conclusions: Final five-year outcomes of the TIDE trial comparing TiNO stents with E-ZES revealed increased rates of MACE driven primarily by clinically indicated TVR. The TIDE trial is registered at ClinicalTrials.gov: NCT00492908.

Adaptive, convergent origins of the pygmy phenotype in African rainforest hunter-gatherers

Tropical rainforest hunter-gatherer populations worldwide share the pygmy phenotype, or small human body size. The evolutionary history of this phenotype is largely unknown. Here we studied DNA from the Batwa, a rainforest hunter-gatherer population from east central Africa, to identify regions of the Batwa genome that underlie the pygmy phenotype. We then performed population genomic analyses to study the evolution of these regions, including comparisons with the Baka, a west central African rainforest hunter-gatherer population. We conclude that the pygmy phenotype likely arose due to positive natural selection and that it arose possibly multiple times within Africa. These results support longstanding anthropological hypotheses that small body size confers an important selective advantage for human rainforest hunter-gatherers.

Dopaminergic denervation severity depends on COMT Val158Met polymorphism in Parkinson's disease.

BACKGROUND Catecholamine-O-methyl-tranferase (COMT) initiates dopamine degradation. Its activity is mainly determined by a single nucleotide polymorphism in the COMT gene (Val158Met, rs4680) separating high (Val/Val, COMT(HH)), intermediate (Val/Met, COMT(HL)) and low metabolizers (Met/Met, COMT(LL)). We investigated dopaminergic denervation in the striatum in PD patients according to COMT rs4680 genotype. METHODS Patients with idiopathic PD were assessed for motor severity (UPDRS-III rating scale in OFF-state), dopaminergic denervation using [123I]-FP-CIT SPECT imaging, and genotyped for the COMT rs4680 enzyme. [123I]-FP-CIT binding potential (BP) for each voxel was defined by the ratio of tracer-binding in the region of interest (striatum, caudate nucleus and putamen) to that in a region of non-specific activity. Genotyping was performed using TaqMan(®) SNP genotyping assay. We used a regression model to evaluate the effect of COMT genotype on the BP in the striatum and its sub-regions. RESULTS Genotype distribution was: 11 (27.5%) COMT(HH), 26 (65%) COMT(HL) and 3 (7.5%) COMT(LL). There were no significant differences in disease severity, treatments, or motor scores between genotypes. When adjusted to clinical severity, gender and age, low and intermediate metabolizers showed significantly higher rates of striatal denervation (COMT(HL+LL) BP = 1.32 ± 0.04) than high metabolizers (COMT(HH), BP = 1.6 ± 0.08; F(1.34) = 9.0, p = 0.005). Striatal sub-regions showed similar results. BP and UPDRS-III motor scores (r = 0.44, p = 0.04) (p < 0.001) were highly correlated. There was a gender effect, but no gender-genotype interaction. CONCLUSIONS Striatal denervation differs according to COMT-Val158Met polymorphism. COMT activity may play a role as a compensatory mechanism in PD motor symptoms.

A meta-analysis of 16 randomized trials of sirolimus-eluting stents versus paclitaxel-eluting stents in patients with coronary artery disease

OBJECTIVES: Our purpose was to make a synthesis of the available evidence on the relative efficacy and safety of 2 drug-eluting stents (DES)--sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES)--in patients with coronary artery disease. BACKGROUND: It is not known whether there are differences in late outcomes between the 2 most commonly used DES: SES and PES. METHODS: Sixteen randomized trials of SES versus PES with a total number of 8,695 patients were included in this meta-analysis. A full set of individual outcome data from 5,562 patients was also available. Mean follow-up period ranged from 9 to 37 months. The primary efficacy end point was the need for reintervention (target lesion revascularization). The primary safety end point was stent thrombosis. Secondary end points were death and recurrent myocardial infarction (MI). RESULTS: No significant heterogeneity was found across trials. Compared with PES, SES significantly reduced the risk of reintervention (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.63 to 0.87, p < 0.001) and stent thrombosis (HR 0.66; 95% CI 0.46 to 0.94, p = 0.02) without significantly impacting on the risk of death (HR 0.92; 95% CI 0.74 to 1.13, p = 0.43) or MI (HR 0.84; 95% CI 0.69 to 1.03, p = 0.10). CONCLUSIONS: Sirolimus-eluting stents are superior to PES in terms of a significant reduction of the risk of reintervention and stent thrombosis. The risk of death was not significantly different between the 2 DES, but there was a trend toward a higher risk of MI with PES, especially after the first year from the procedure.
