Urban Sustainability Strategies Guided by the SDGs —A Tale of Four Cities

The United Nations (UN) 2030 Sustainable Development Agenda, signed in 2015 and backed-up with its seventeen Sustainable Development Goals (SDGs), mentions cities as key players for evolving actively towards more sustainability. This underpins that living in the cities of the urban age is increasingly becoming the focus of sustainability discussions, which is particularly reflected in SDG 11 “Making cities and human settlements inclusive, safe, resilient and sustainable”. As urban sustainability strategies are playing a key role for the development of cities, this article sheds light on four cities’ sustainability strategies. The case studies highlight shortcomings, in terms of integrated visions, clear targets, and indicators in existing urban (sustainability) strategies. The article discusses these issues in light of an analytical framework, and stresses challenges and opportunities that SDG implementation involves.
Prevalence of and risk factors for lifetime suicide attempts among blacks in the United States.

CONTEXT Lack of data on the lifetime prevalence and age at onset of suicide ideation, plans, and attempts among blacks in the United States limits the creation and evaluation of interventions to reduce suicide among black Americans. OBJECTIVE To examine the prevalence and correlates of suicide ideation, planning, and attempts across 2 ethnic classifications of blacks in a nationally representative sample. DESIGN, SETTING, AND PARTICIPANTS Data are from the National Survey of American Life, a national household probability sample of 5181 black respondents aged 18 years and older, conducted between February 2001 and June 2003, using a slightly modified adaptation of the World Health Organization World Mental Health version of the Composite International Diagnostic Interview. Bivariate and survival analyses were used to delineate patterns and correlates of nonfatal suicidal behavior. MAIN OUTCOME MEASURES Self-reports of lifetime suicide ideation, planning, and attempts. RESULTS Survey respondents, categorized as African Americans and Caribbean Americans, reported lifetime prevalence of 11.7% for suicide ideation and 4.1% for attempts. Among the respondents who reported ideation, 34.6% transitioned to making a plan and only 21% made an unplanned attempt. Among 4 ethnic-sex groups, the 7.5% lifetime prevalence for attempts among Caribbean black men was the highest among black Americans. The greatest risk of progressing to suicide planning or attempt among ideators occurred within the first year after ideation onset. Blacks at higher risk for suicide attempts were in younger birth cohorts, less educated, Midwest residents, and had 1 or more Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition disorders. CONCLUSIONS This study documents the burden of nonfatal suicidality among US blacks, notably Caribbean black men, and individuals making planned attempts. Advancing research on the transition from suicide planning to attempt is vital to the efficacy of health care professionals' ability to screen blacks at risk for suicide.
Effects of antimicrobial therapy on sperm-mucus interaction.

Sperm-mucus interaction under in-vitro or in-vivo conditions might be affected by microorganisms colonizing the reproductive tract. In order to study the influence of antimicrobial therapy, an extensive microbial screening was performed including Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum, Neisseria gonorrhoeae, a broad spectrum of potentially pathogenic aerobic and anaerobic bacteria, Trichomonas vaginalis, herpes simplex virus and yeasts. One-hundred-and-six couples with a mean duration of infertility of 5.5 years (range 1-12 years) and with isolation of potentially pathogenic microorganisms in semen samples and/or cervical swabs were submitted to a prospective pilot study. None of the patients displayed signs or symptoms of infection in the lower genital tract. Before and after specific therapy, based on antimicrobial susceptibility testing, sperm analyses and in-vitro sperm penetration meter tests (SPMT) (Kremer) were performed. SPMT was evaluated with cervical mucus of patients' wives, collected after a standardized oral treatment with oestrogens and, additionally, in a crossed manner with cervical mucus and spermatozoa of fertile donors. The success of antimicrobial therapy was controlled by repeating the same microbial screening and was 96%. However, there was a marked change in the microbial pattern. A comparison of the results of sperm analyses before and after treatment revealed neither significant differences for sperm volume, sperm count, propulsive motility, morphology, vitality, pH, fructose concentration or number of round cells, nor was there a significant influence on the cervical index and the number of leukocytes in cervical mucus.

[Results of pegylated interferon and ribavirin for the treatment of chronic hepatitis C in clinical practice: a 5-year experience].

INTRODUCTION Numerous clinical trials have demonstrated the efficacy of treatment with pegylated interferon and ribavirin but little is known about the results obtained in clinical practice. OBJECTIVE To evaluate treatment response and factors influencing the treatment of chronic hepatitis C in clinical practice. MATERIAL AND METHODS Between August 2001 and December 2005, we treated 219 patients with pegylated interferon (alpha 2a -fixed dose, or alpha 2b, according to weight) and ribavirin. Patients with genotype 1 or 4 received treatment with pegylated interferon alpha 2a (180 microg/week) and ribavirin (1000 mg/day if body weight was <75 kg or 1200 mg/day if body weight was >75 kg) or interferon alpha 2b (1.5 microg/kg/week) and ribavirin (10.6 mg/kg/day) for 48 weeks. Patients with genotype 2 or 3 were treated for 24 weeks with the same regimen of pegylated interferon alpha-2a or alpha-2b, but with 800 mg of ribavirin divided in two daily doses. Sustained viral response was defined as absence of HCV-RNA 6 months after the end of treatment. RESULTS A total of 219 patients were included (69% men; mean age 44+/-10). As epidemiological antecedents, 22.4% of the treated patients had previously consumed drugs parenterally and 22.4% had received blood transfusions before 1992. Forty-seven percent of the patients with liver biopsy had fibrosis bridges or established liver cirrhosis. The genotype was distributed as follows: 69.8% genotype 1, 4.1% genotype 2, 17.8% genotype 3, and 8.2% genotype 4. Of the 219 patients, 76 (35%) were treated with pegylated interferon alpha 2a and 143 (65%) with interferon alpha 2b. Analysis of response by genotype revealed that sustained viral response was obtained in 46% genotype 1, 88.9% genotype 2, 78.9% genotype 3, and 33.3% genotype 4. Univariate analysis showed that the only variable influencing sustained viral response was genotype. CONCLUSION Treatment with pegylated interferon and ribavirin in clinical practice shows a similar pattern of sustained viral response to that obtained in clinical research. The main variable correlated with sustained viral response continues to be viral genotype.
Warmer winters reduce frog fecundity and shift breeding phenology, which consequently alters larval development and metamorphic timing

One widely documented phenological response to climate change is the earlier occurrence of spring‐breeding events. While such climate change‐driven shifts in phenology are common, their consequences for individuals and populations have rarely been investigated. I addressed this gap in our knowledge by using a multi‐year observational study of six wood frog (Rana sylvatica) populations near the southern edge of their range. I tested first if winter temperature or precipitation affected the date of breeding and female fecundity, and second if timing of breeding affected subsequent larval development rate, mass at metamorphosis, date of metamorphosis, and survival. Warmer winters were associated with earlier breeding but reduced female fecundity. Winter precipitation did not affect breeding date, but was positively associated with female fecundity. There was no association between earlier breeding and larval survival or mass at metamorphosis, but earlier breeding was associated with delayed larval development. The delay in larval development was explained through a counterintuitive correlation between breeding date and temperature during larval development. Warmer winters led to earlier breeding, which in turn was associated with cooler post‐breeding temperatures that slowed larval development. The delay in larval development did not fully compensate for the earlier breeding, such that for every 2 days earlier that breeding took place, the average date of metamorphosis was 1 day earlier. Other studies have found that earlier metamorphosis is associated with increased postmetamorphic growth and survival, suggesting that earlier breeding has beneficial effects on wood frog populations.
Clinical pharmacology of analgesics assessed with human experimental pain models: bridging basic and clinical research

The medical impact of pain is such that much effort is being applied to develop novel analgesic drugs directed towards new targets and to investigate the analgesic efficacy of known drugs. Ongoing research requires cost‐saving tools to translate basic science knowledge into clinically effective analgesic compounds. In this review we have re‐examined the prediction of clinical analgesia by human experimental pain models as a basis for model selection in phase I studies. The overall prediction of analgesic efficacy or failure of a drug correlated well between experimental and clinical settings. However, correct model selection requires more detailed information about which model predicts a particular clinical pain condition. We hypothesized that if an analgesic drug was effective in an experimental pain model and also a specific clinical pain condition, then that model might be predictive for that particular condition and should be selected for development as an analgesic for that condition. The validity of the prediction increases with an increase in the numbers of analgesic drug classes for which this agreement was shown. From available evidence, only five clinical pain conditions were correctly predicted by seven different pain models for at least three different drugs. Most of these models combine a sensitization method. The analysis also identified several models with low impact with respect to their clinical translation. Thus, the presently identified agreements and non‐agreements between analgesic effects on experimental and on clinical pain may serve as a solid basis to identify complex sets of human pain models that bridge basic science with clinical pain research.
BAFF synthesis by rheumatoid synoviocytes is positively controlled by alpha5beta1 integrin stimulation and is negatively regulated by tumor necrosis factor alpha and Toll-like receptor ligands.

OBJECTIVE It was recently demonstrated that synoviocytes (FLS) from rheumatoid arthritis (RA) patients express BAFF transcripts that are up-regulated by tumor necrosis factor alpha (TNFalpha) and interferon-gamma (IFNgamma). Thus, BAFF increases in RA target cells might be related to activation of the receptors of innate immunity. The purpose of this study was to determine whether ligands of Toll-like receptor 2 (TLR-2), TLR-4, TLR-9, and alpha5beta1 integrin are able to induce BAFF synthesis by RA FLS. METHODS Quantitative reverse transcription-polymerase chain reaction analyses and enzyme-linked immunosorbent assays were performed to evaluate BAFF messenger RNA induction and BAFF release from FLS after stimulation by ligands for TLR-2, TLR-4, TLR-9, alpha5beta1 integrin (bacterial lipopeptide [BLP] palmitoyl-3-cysteine-serine-lysine-4, lipopolysaccharide [LPS], CpG, and protein I/II, respectively), TNFalpha, and IFNgamma. RESULTS In contrast to IFNgamma, neither TNFalpha, LPS, BLP, nor CpG induced the de novo synthesis and release of BAFF by FLS. Priming of cells with IFNgamma did not have a synergistic effect on BAFF synthesis by FLS stimulated with bacterial products known as pathogen-associated molecular patterns. Moreover, we found that IFNgamma-induced BAFF synthesis is inhibited by simultaneous stimulation with either TLR ligands or TNFalpha. We also showed that interplay between TLRs, TNF receptors, and IFNgamma signaling induces the expression of suppressor of cytokine signaling 1 (SOCS-1) and SOCS-3 and reduces IFNgamma-dependent STAT-1 phosphorylation, which might explain this inhibition. In contrast, we demonstrated that stimulation of alpha5beta1 integrin can induce BAFF synthesis and release per se and that stimulation of this pathway has no inhibitory effect on IFNgamma-induced BAFF synthesis. CONCLUSION Our findings indicate that BAFF secretion by resident cells in target organs of autoimmunity is tightly regulated by innate immunity, with positive and negative controls, depending on the receptors and the pathways triggered.
Tracking Mutant Huntingtin Aggregation Kinetics in Cells Reveals Three Major Populations That Include an Invariant Oligomer Pool*

Huntington disease is caused by expanded polyglutamine sequences in huntingtin, which procures its aggregation into intracellular inclusion bodies (IBs). Aggregate intermediates, such as soluble oligomers, are predicted to be toxic to cells, yet because of a lack of quantitative methods, the kinetics of aggregation in cells remains poorly understood. We used sedimentation velocity analysis to define and compare the heterogeneity and flux of purified huntingtin with huntingtin expressed in mammalian cells under non-denaturing conditions. Non-pathogenic huntingtin remained as hydrodynamically elongated monomers in vitro and in cells. Purified polyglutamine-expanded pathogenic huntingtin formed elongated monomers (2.4 S) that evolved into a heterogeneous aggregate population of increasing size over time (100–6,000 S). However, in cells, mutant huntingtin formed three major populations: monomers (2.3 S), oligomers (mode s20,w = 140 S) and IBs (mode s20,w = 320,000 S). Strikingly, the oligomers did not change in size heterogeneity or in their proportion of total huntingtin over 3 days despite continued monomer conversion to IBs, suggesting that oligomers are rate-limiting intermediates to IB formation. We also determined how a chaperone known to modulate huntingtin toxicity, Hsc70, influences in-cell huntingtin partitioning. Hsc70 decreased the pool of 140 S oligomers but increased the overall flux of monomers to IBs, suggesting that Hsc70 reduces toxicity by facilitating transfer of oligomers into IBs. Together, our data suggest that huntingtin aggregation is streamlined in cells and is consistent with the 140 S oligomers, which remain invariant over time, as a constant source of toxicity to cells irrespective of total load of insoluble aggregates.
Effect of primary care treatment of depression on service use by patients with high medical expenditures.

OBJECTIVE The study examined the impact of identifying and treating depression among patients who had a history of high medical expenditures. Effects on service use, disability, and quality of life were measured. METHODS A total of 786 high users of services from two primary care clinics and an equal number of randomly selected patients who were not high users were screened for depression using the Medical Outcomes Study (MOS) depression screen. High-user patients who screened positive were subsequently seen by their primary care physician for a diagnostic interview. The 20 patients with a confirmed diagnosis of depression were offered open-label antidepressant treatment by their primary care physician for six months. RESULTS All 20 patients completed the six-month study. Treatment resulted in significant reductions in depression and significant improvements in quality of life in the areas of social functioning, general health, mental health, physical functioning, emotional role functioning, and vitality. Days of missed work per month were reduced, and the percentage of patients who reported not being at all impaired by their depression at work increased. Costs for service use fell from $13.28 to $6.75 per day; when costs for the treatment study were added, the daily service use cost was $12.55. CONCLUSIONS Identification and treatment of depression among patients with a history of high medical expenditures improved depression and increased work productivity and quality of life. Service use decreased with treatment. A larger sample and control group are needed to determine if treatment is associated with a statistically significant decrease in medical expenditures.
Validation of a single screening question for problem drinking.

OBJECTIVE The researchers hoped to confirm the sensitivity and specificity of a single screening question for problem drinking: "When was the last time you had more than X drinks in 1 day? ", where X=4 for women and X=5 for men. STUDY DESIGN Cross-sectional study. POPULATION Adult patients presenting to 3 emergency departments in Boone County, Missouri, for care within 48 hours of an injury. OUTCOMES MEASURED The answers to the question were coded as never, more than 12 months ago, 3 to 12 months ago, and within the past 3 months. Problematic drinking was defined as either hazardous drinking (identified by a 29-day retrospective interview) or a past-year alcohol use disorder (defined by questions from the Diagnostic Interview Schedule). RESULTS There was a 70% participation rate. Of 2517 interviewed patients: 29% were hazardous drinkers; 20% had a past-year alcohol use disorder; and 35% had either or both. Considering "within the last 3 months" as positive, the sensitivity of the single question was 86%, and the specificity was 86%. In men (n=1432), sensitivity and specificity were 88% and 81%; in women, 83% and 91%. Using the 4 answer options for the question, the area under the receiver-operating characteristic curve was 0.90. Controlling for age, sex, tobacco use, injury severity, and breath alcohol level in logistic regression models changed the findings minimally. CONCLUSIONS A single question about the last episode of heavy drinking has clinically useful sensitivity and specificity in detecting hazardous drinking and alcohol use disorders.
Cytosolic calcium changes in individual neutrophils stimulated by opsonized and unopsonized Candida albicans hyphae

Previous experiments suggest the critical central role of the neutrophil (PMN) respiratory burst in the prevention and containment of disseminated candidiasis. A rise in cytosolic free calcium concentrations ([Ca2+]i) has been documented as an early event after PMN stimulation which is involved in the subsequent genesis of microbicidal and inflammatory respiratory burst products. [Ca2+]i were therefore determined in individual PMN, loaded with the fluorescent calcium probe fura-2 as they attached to and spread over serum-opsonized or unopsonized Candida albicans hyphae, particles that are too big to be completely ingested. After contact between hyphae and PMN, the PMN rapidly spread over hyphal surfaces. Although both opsonized and unopsonized hyphae stimulated similar magnitudes of peak median increases in PMN [Ca2+]i, the kinetics of responses differed; median [Ca2+]i peaked within 1 min after contact with opsonized hyphae versus 4 min after contact with unopsonized hyphae. Moreover, a detectable calcium transient did not invariably follow contact and spreading of each individual PMN over a hyphal surface. In contrast to patterns seen after stimulation of PMN with opsonized zymosan, in which [Ca2+]i is greatest in the periphagosomal region, there was a more uniform distribution throughout the cytoplasm in PMN stimulated with the noningestable hyphae. These alterations in the early patterns and timing of PMN stimulation may reflect analogous differences in subsequent events which control the efficiency and specificity of microbicidal responses to uningestible hyphae and which also determine whether host tissues are damaged by the generation of toxic PMN activation products.
Effects of thiol compounds on in vitro maturation of canine oocytes collected from different reproductive stages

Various thiol compounds are known to improve cytoplasmic and/or nuclear maturation of oocytes in vitro. The present study examined the effects of two thiol compounds, cysteine (0.1, 0.5, and 1.0 mM) and cysteamine (50, 100, and 200 µM), on cytoplasmic and nuclear maturation of canine oocytes. Oocytes collected from different reproductive stages were cultured in TCM‐199 supplemented with 10% fetal bovine serum, 2.2 mg/ml sodium carbonate, 2.0 µg/ml estrogen, 0.5 µg/ml FSH, 0.03 IU/ml hCG, and 1% penicillin–streptomycin solution for 72 h. Data were analyzed by two‐way ANOVA after arcscine transformation and protected by Bonferroni post hoc test. The effects of cysteine and cysteamine on canine IVM were varied depending on the reproductive stage of oocyte donor bitches. In the follicular stage, significantly more oocytes reached the metaphase II (M II) stage when cultured with 0.5 or 1.0 mM cysteine (16.7% and 16.9%, respectively) compared to the control (6.2%). In the follicular stage, cysteamine increased oocyte maturation rate upto the M II stage (15.1% to 17.0%) compared to the control (4.4%). Both the 0.5 mM cysteine and 100 µM cysteamine, alone or together, increased the intracellular GSH level of canine oocytes compared to the control. Irrespective of reproductive stage, no further beneficial effects on nuclear or cytoplasmic maturation were observed when 0.5 mM cysteine and 100 µM cysteamine were supplemented together. In conclusion, addition of 0.5 mM cysteine and 100 µM cysteamine to the maturation medium improved IVM of canine oocytes. Mol. Reprod. Dev. 74: 1213–1220, 2007. © 2007 Wiley‐Liss, Inc.
Results of a prospective phase II trial with oral low-dose bexarotene plus photochemotherapy (PUVA) in refractory and/or relapsed patients with mycosis fungoides

IntroductionBexarotene is a synthetic retinoid effective in early and advanced stages of mycosis fungoides (MF)/Sezary Syndrome (SS) both in monotherapy and combination schemes.ObjectivesWe aimed to assess disease response to low-dose bexarotene and PUVA in maintenance in refractory and/or resistant patients with early and advanced stage MF/SS.MethodsWe followed prospectively 21 patients (stages IB-IV): 15 with early stage MF and 6 with advanced disease. “Mini” and standard protocols were respectively applied to patients who failed PUVA or several systemic regimens. The dose of bexarotene and the administration of PUVA were titrated individually and tailored during induction and maintenance according to previous therapy, disease stage and toxicity. We evaluated overall response (OR) at the end of maintenance, safety and event-free survival (EFS). ResultsAfter induction phase, OR was 85.6%, higher in early MF (93.4%) than in advanced disease (66.6%). At the end of maintenance, OR was 76.2%, including 33.3% of CR. Median EFS for the whole group was 31 months. Bexarotene was well tolerated regarding the side effects, with prophylaxis and progressive drug increase in the induction phase of the protocol. Side effects were mainly of low and moderate grades.ConclusionsWe observed a favorable rate of therapeutic effects and few, generally mild, side effects with low doses of bexarotene combined with PUVA.
