Pilot Study to Develop a Rapid Assessment of Tuberculosis Care-Seeking and Adherence Practices in Rural Limpopo Province, South Africa

Studies of factors influencing tuberculosis (TB) care-seeking and treatment adherence in high TB/HIV co-burden African countries have typically surveyed urban patients' sociodemographic characteristics. To understand community perceptions and guide rapid assessment interviews, we interviewed key informants (nurses, tribal leaders, n = 9) and local researchers (n = 3) in poor, rural areas of South Africa. HIV-related stigma and misperceptions about TB causes and symptoms were cited as barriers. Key informants said older people preferred traditional healers; local researchers heard a preference for “western” care and suggested supporting clinic staff travel to remote villages with health education and diagnostic services. Key informants said not understanding the consequences of incomplete treatment and reluctance to relinquish disability grants decreased adherence. All reported that non-family DOTS supporters provided invaluable support. Rapid assessment should include drop-outs, re-treated, and co-infected patients and ask questions examining origins of misperceptions, stigma of testing, and pre-test messages to improve community perceptions about TB care-seeking and treatment adherence.
No Absolutism Here

Moral absolutism is the idea that people’s moral judgments are insensitive to considerations of harm. Scott, Inbar, and Rozin (2016, this issue) claim that most moral opponents to genetically modified organisms are absolutely opposed—motivated by disgust and not harm. Yet there is no evidence for moral absolutism in their data. Perceived risk/harm is the most significant predictor of moral judgments for “absolutists,” accounting for 30 times more variance than disgust. Reanalyses suggest that disgust is not even a significant predictor of the moral judgments of absolutists once accounting for perceived harm and anger. Instead of revealing actual moral absolutism, Scott et al. find only empty absolutism: hypothetical, forecasted, self-reported moral absolutism. Strikingly, the moral judgments of so-called absolutists are somewhat more sensitive to consequentialist concerns than those of nonabsolutists. Mediation reanalyses reveal that moral judgments are most proximally predicted by harm and not disgust, consistent with dyadic morality.
An Evaluation of the Effect of Anesthetic Technique on Reproductive Success after Laparoscopic Pronuclear Stage Transfer: Propofol/Nitrous Oxide Versus Isoflurane/Nitrous Oxide

Background Laparoscopic pronuclear stage transfer (PROST) is the preferred method of embryo transfer after in vitro fertilization in many infertility programs. There are scant data to recommend the use or avoidance of any particular anesthetic agent for use in women undergoing this procedure. The authors hypothesized that propofol would be an ideal anesthetic for laparoscopic PROST because of its characteristic favorable recovery profile that includes minimal sedation and a low incidence of postoperative nausea and vomiting. The purpose of the study was to compare propofol and isoflurane with respect to postanesthetic recovery and pregnancy outcomes after laparoscopic PROST. Methods One hundred twelve women scheduled for laparoscopic PROST were randomized to receive either propofol/nitrous oxide or isoflurane/nitrous oxide for maintenance of anesthesia. Results Visual analog scale scores for sedation were lower in the propofol group than in the isoflurane group at all measurements between 30 min and 3 h after surgery. More women experienced emesis and were given an antiemetic during recovery in the isoflurane group than in the propofol group. However, the percentage of pregnancies with evidence of fetal cardiac activity was 54% in the isoflurane group compared with only 30% in the propofol group (P = 0.023). Also, the ongoing pregnancy rate was greater in the isoflurane group than in the propofol group (54% vs. 29%, P = 0.014). Conclusions Propofol/nitrous oxide anesthesia was associated with lower clinical and ongoing pregnancy rates compared with isoflurane/nitrous oxide anesthesia.
A Reliable Asynchronous Protocol for VLC Communications Based on the Rolling Shutter Effect

In this paper we introduce a novel reliable asynchronous protocol that allows to establish a VLC link between a LED luminary and an off-the- shelf smartphone. Our protocol and decoding algorithms benefit from the access to advanced camera settings available in the latest generations of mobile devices to outperform previous VLC designs in the state of the art. In particular, in the paper we provide an experimental evaluation using a commercial Nexus 5 device where it is shown how our designed prototype can achieve transmission speeds of up to 700 bps and operating distances of up to 3 meters. The previous performance figures have the potential to spark a wide set of novel applications.
Role of beta‐blockers in patients admitted for worsening heart failure in a real world setting: data from the Italian Survey on Acute Heart Failure †

Randomized trials have shown that beta‐blockers (BBs) reduce mortality in chronic heart failure (HF). Less data are available on the role of BBs in patients with acute HF, specifically if BBs should be continued or temporarily withdrawn. The aim of this study was to evaluate the role of BBs on in‐hospital outcomes of patients admitted for worsening HF in a Cardiology setting.
Fallback foods of temperate-living primates: a case study on snub-nosed monkeys.

Only a few primate species thrive in temperate regions characterized by relatively low temperature, low rainfall, low species diversity, high elevation, and especially an extended season of food scarcity during which they suffer from dietary stress. We present data of a case study of dietary strategies and fallback foods in snub-nosed monkeys (Rhinopithecus bieti) in the Samage Forest, Northwest Yunnan, PRC. The snub-nosed monkeys adjusted intake of plant food items corresponding with changes in the phenology of deciduous trees in the forest and specifically showed a strong preference for young leaves in spring. A non-plant food, lichens (Parmeliaceae), featured prominently in the diet throughout the year (annual representation in the diet was about 67%) and became the dominant food item in winter when palatable plant resources were scarce. Additional highly sought winter foods were frost-resistant fruits and winter buds of deciduous hardwoods. The snub-nosed monkeys' choice of lichens as a staple fallback food is likely because of their spatiotemporal consistency in occurrence, nutritional and energetic properties, and the ease with which they can be harvested. Using lichens is a way to mediate effects of seasonal dearth in palatable plant foods and ultimately a key survival strategy. The snub-nosed monkeys' fallback strategy affects various aspects of their biology, e.g., two- and three-dimensional range use and social organization. The higher abundance of lichens at higher altitudes explains the monkeys' tendency to occupy relatively high altitudes in winter despite the prevailing cold. As to social organization, the wide temporal and spatial availability of lichens strongly reduces the ecological costs of grouping, thus allowing for the formation of "super-groups. " Usnea lichens, the snub-nosed monkeys' primary dietary component, are known to be highly susceptible to human-induced environmental changes such as air pollution, and a decline of this critical resource base could have devastating effects on the last remaining populations. Within the order Primates, lichenivory is a rare strategy and only found in a few species or populations inhabiting montane areas, i.e., Macaca sylvanus, Colobus angolensis, and Rhinopithecus roxellana. Other temperate-dwelling primates rely mainly on buds and bark as winter fallback foods.
Value of distal colon washout in civilian rectal trauma--reducing gut bacterial translocation.

Recent experience with civilian rectal trauma challenges the military dictum advocating routine distal colon washout. Opponents contend that septic morbidity is not influenced by perioperative removal of feces from the rectosigmoid region. In an effort to elucidate this issue, we reviewed 27 consecutive patients sustaining extraperitoneal rectal trauma over the past 5 years. One patient, exsanguinating from abdominal vascular injury, was excluded from further analysis. In the remaining 26 patients, rectal injury was due to gunshot wound in 16 (62%), pelvic fracture in 8 (31%), and stab wound in 2 (7%). The mean Revised Trauma Score was 6.9 +/- 0.4, Abdominal Trauma Index 20.9 +/- 8.1, and Injury Severity Score 28.6 +/- 11.0. Proximal colostomy was done in all patients and presacral drains were placed in 23 (88%). Broad-spectrum antibiotics were administered for a minimum of 5 days. Thirteen (50%) of the group underwent intraoperative washout of the distal rectosigmoid colon, dictated by attending surgeon's preference; the other half did not. These two groups were otherwise comparable with respect to injury mechanism, shock on arrival, rectal wound severity, associated injuries, and perioperative blood transfusions. Major complications were greater in the no-washout versus washout groups: pelvic abscess, 46% vs. 8%; rectal fistulae, 23% vs. 8%; and sepsis, 15% vs. 8%. The single death (4%) occurred in the no-washout group. Although based on a small group of patients, these trends imply that distal colon washout reduces septic morbidity following civilian rectal trauma. (ABSTRACT TRUNCATED AT 250 WORDS)
Human Antibody Response to Aedes albopictus Salivary Proteins: A Potential Biomarker to Evaluate the Efficacy of Vector Control in an Area of Chikungunya and Dengue Virus Transmission

Aedes borne viruses represent public health problems in southern countries and threat to emerge in the developed world. Their control is currently based on vector population control. Much effort is being devoted to develop new tools to control such arbovirus. Recent findings suggest that the evaluation of human antibody (Ab) response to arthropod salivary proteins is relevant to measuring the level of human exposure to mosquito bites. Using an immunoepidemiological approach, the present study aimed to assess the usefulness of the salivary biomarker for measuring the efficacy of Ae. albopictus control strategies in La Reunion urban area. The antisaliva Ab response of adult humans exposed to Ae. albopictus was evaluatedbefore and after vector control measures. Our results showed a significant correlation between antisaliva Ab response and the level of exposure to vectors bites. The decrease of Ae. albopictus density has been detected by this biomarker two weeks after the implementation of control measures, suggesting its potential usefulness for evaluating control strategies in a short time period. The identification of species specific salivary proteins/peptides should improve the use of this biomarker.
Single-institution experience with pemetrexed and bevacizumab as salvage therapy in advanced non-small-cell lung cancer.

BACKGROUND Second-line cytotoxic therapy for patients with advanced non-small-cell lung cancer (NSCLC) includes single-agent pemetrexed or docetaxel. The addition of bevacizumab to carboplatin/paclitaxel in the first-line setting was shown to improve survival and response. We assessed pemetrexed and bevacizumab compared with pemetrexed alone in the salvage setting. PATIENTS AND METHODS Patients with advanced NSCLC, in whom at least first-line therapy failed and who received pemetrexed alone or pemetrexed/bevacizumab, were analyzed. RESULTS From March 2005 through March 2006, we identified 25 patients treated with pemetrexed or pemetrexed/bevacizumab in the salvage setting. There were no significant differences in clinical features. All 25 were evaluable for overall survival, 21 for time to progression, and 19 for objective response evaluation. After a median follow-up of 9.3 months, there were no differences between the cohorts for median overall survival, time to progression, or objective disease control rate (partial response and stable disease). The 6-month survival rate was 56.3% for the pemetrexed group and 66.7% for the pemetrexed/bevacizumab group. There were no grade 3-5 hemorrhagic events. CONCLUSION This retrospective single institution analysis showed that pemetrexed/bevacizumab was safely administered in the salvage setting of advanced NSCLC. Whether bevacizumab enhances the efficacy of pemetrexed remains to be determined and is the subject of an ongoing randomized clinical trial. Until those results are reported, off-label use of pemetrexed and bevacizumab is not recommended.
Ensemble Adversarial Training: Attacks and Defenses

Adversarial examples are perturbed inputs designed to fool machine learning models. Adversarial training injects such examples into training data to increase robustness. To scale this technique to large datasets, perturbations are crafted using fast single-step methods that maximize a linear approximation of the model's loss. We show that this form of adversarial training converges to a degenerate global minimum, wherein small curvature artifacts near the data points obfuscate a linear approximation of the loss. The model thus learns to generate weak perturbations, rather than defend against strong ones. As a result, we find that adversarial training remains vulnerable to black-box attacks, where we transfer perturbations computed on undefended models, as well as to a powerful novel single-step attack that escapes the non-smooth vicinity of the input data via a small random step. We further introduce Ensemble Adversarial Training, a technique that augments training data with perturbations transferred from other models. On ImageNet, Ensemble Adversarial Training yields models with strong robustness to black-box attacks. In particular, our most robust model won the first round of the NIPS 2017 competition on Defenses against Adversarial Attacks. However, subsequent work found that more elaborate black-box attacks could significantly enhance transferability and reduce the accuracy of our models.
Cell-dependent Antitumor Immunity Mediated by Secondary Lymphoid Tissue Chemokine : Augmentation of Dendritic Cell-based Immunotherapy 1

Secondary lymphoid tissue chemokine (SLC) is a CC chemokine that is selective in its recruitment of naı̈ve T cells and dendritic cells (DCs). In the lymph node, SLC is believed to play an important role in the initiation of an immune response by colocalizing naı̈ve T cells with DC-presenting antigen. Here, we used SLC as a treatment for tumors established from the poorly immunogenic B16 melanoma. Intratumoral injections of SLC inhibited tumor growth in a CD81, T cell-dependent manner. SLC elicited a substantial infiltration of DCs and T cells into the tumor, coincident with the antitumor response. We next usedSLC gene-modified DCs as a treatment of established tumors. Intratumoral injections of SLC-expressing DCs resulted in tumor growth inhibition that was significantly better than either control DCs or SLC alone. Distal site immunization of tumorbearing mice with SLC gene-modified DCs pulsed with tumor lysate elicited an antitumor response whereas control DCs did not. We also found that s.c. injection of lysate-pulsed DCs expressing SLC promoted the migration of T cells to the immunization site. This report demonstrates that SLC can both induce antitumor responses and enhance the antitumor immunity elicited by DCs.
Inhibitory effect of uremic solutions on protein‐DNA‐complex formation of the vitamin D receptor and other members of the nuclear receptor superfamily

Chronic renal failure is often associated with a resistance to the biologically active form of vitamin D3, the nuclear hormone 1α,25‐dihydroxyvitamin D3 (VD). The actions of VD are mediated by the vitamin D receptor (VDR), a ligand‐dependent transcription factor that binds as a dimeric complex with the retinoid X receptor (RXR) to specific DNA binding sites in the promoter regions of primary VD responding genes, referred to as VD response elements (VDREs). It could be shown in this study that uremic solutions derived from ultrafiltrate from hemodialysis patients and dialysate from peritoneal dialysis patients had an inhibitory effect on the complex formation and ligand inducibility of VDR‐RXR heterodimers on different VDRE types. This inhibition was attributed to the formation of Schiff bases between “reactive aldehydes” and lysine residues of the DNA binding domain (DBD) of the VDR, but point mutagenesis data of different lysine residues in this study could not confirm this idea. However, the inhibitory effect of uremic solutions could also be observed for the complex formation of other homo‐ or heterodimer forming nuclear receptors, whereas an as a monomer binding nuclear receptor did not appear to be affected. These results indicate that VDR is a target of substances in uremic solutions in vitro, but also to some extent other nuclear receptors (i.e., other endocrine signaling systems) may be affected by renal failure.

Predicting neurocognitive function with hippocampal volumes and DTI metrics in patients with Alzheimer's dementia and mild cognitive impairment

Cognitive performance in patients with Alzheimer's dementia (AD) and mild cognitive impairment (MCI) has been reported to be related to hippocampal atrophy and microstructural changes in white matter (WM). We aimed to predict the neurocognitive functions of patients with MCI or AD using hippocampal volumes and diffusion tensor imaging (DTI) metrics via partial least squares regression (PLSR).
Epstein–Barr virus induction of the Hedgehog signalling pathway imposes a stem cell phenotype on human epithelial cells

Nasopharyngeal carcinoma (NPC) is a cancer common in southern China and South East Asia that is causally linked to Epstein–Barr virus (EBV) infection. Here, we demonstrate that NPC displays frequent dysregulation of the Hedgehog (HH) pathway, a pathway implicated in the maintenance of stem cells, but whose aberrant activation in adult tissues can lead to cancer. Using authentic EBV‐positive carcinoma‐derived cell lines and nasopharyngeal epithelial cell lines latently infected with EBV as models for NPC in vitro, we show that EBV activates the HH signalling pathway through autocrine induction of SHH ligand. Moreover, we find that constitutive engagement of the HH pathway induces the expression of a number of stemness‐associated genes and imposes stem‐like characteristics on EBV‐infected epithelial cells in vitro. Using epithelial cells expressing individual EBV latent genes detected in NPC, we show that EBNA1, LMP1, and LMP2A are all capable of inducing SHH ligand and activating the HH pathway, but only LMP1 and LMP2A are able to induce expression of stemness‐associated marker genes. Our findings not only identify a role for dysregulated HH signalling in NPC oncogenesis, but also provide a novel rationale for therapeutic intervention.

Effect of cholesterol lowering on stiffness of aortic and femoral arterial walls in rabbits on a high fat diet.

BACKGROUND Researches in arterial elasticity have increased over the past few years. We investigated the effects of simvastatin on vascular stiffness in fat fed rabbits by ultrasonography. METHODS Thirty rabbits were assigned randomly to 3 groups: normal control group (A), the cholesterol group (B), simvastatin group (C: high fat diet for 4 weeks and high fat diet + simvastatin for further 4 weeks). Stiffness coefficient, pressure strain elastic modulus and velocity of pulse waves in abdominal aorta and femoral artery were measured by ultrasonographic echo tracking at the end of the 4th and the 8th weeks. RESULTS At the end of the 4th week, stiffness coefficient, pressure strain elastic modulus and pulse wave velocity of femoral artery were significantly increased in group B compared with those in group A. Similarly, at the end of the 8th week, the same parameters of abdominal aorta were significantly increased in group B compared with those in group A. In contrast, stiffness coefficient, pressure strain elastic modulus and pulse wave velocity of femoral artery were significantly decreased in group C compared with those in group B, however, there was no significant difference in parameters of abdominal aorta between groups B and C. CONCLUSION Short term administration of simvastatin can improve the elasticity of femoral artery but not abdominal aorta.
What precipitates deliberate self-harm? A cognitive behavioural formulation of attempted suicide presentations at an inner city hospital.

OBJECTIVE To develop a working model that provides an understanding of the process of deliberate self-harm and a framework for psychological intervention in an emergency department setting. METHOD A retrospective clinical audit of a consecutive series of 51 deliberate self-harm patients referred to the liaison psychiatry service by the emergency department of an inner city hospital. RESULTS Patient characteristics were diverse. The age range was 17-92 years, with 79% between 15 and 35 years. Most were single and unemployed and the majority had a psychiatric disorder. Characteristically, there was at least one immediate stressor and intoxication immediately before the attempt. CONCLUSIONS The diversity of deliberate self-harm patients requires strategic intervention in a setting such as the emergency department. The working model for intervention presented here may be transferable to other settings such as general practice or community mental health centres using an educational and skills development approach with ongoing supervision.
Poverty and Inequality

INTRODUCTION Poverty and inequality have been deeply rooted in Latin American societies since the early colonial era. With the arrival of Spanish and Portuguese conquerors, the diverse resources of the region in terms of land and other factor endowments were carved up in ways that favored the few at the expense of the many. Later, the intensification of colonization brought the development of economic structures that cemented these inequalities in place. Both the diversity of factor endowments in the region and the way in which they have been distributed have therefore played a heavy hand in predisposing Latin America toward certain paths of development – paths characterized by wide-ranging degrees of inequality in wealth, human capital, and political power. The severity of inequality has varied across the continent, depending on many factors. Generally speaking, however, patterns of production, land distribution, and schooling that Latin America has followed have consistently fostered high degrees of inequality. Many of these patterns were formed in the early colonial era, when indigenous populations were denied rights while a select number of elites of European descent were given the lion’s share of wealth, land, and power to administer their conquered territories. The early differences in the extent of inequality persisted and were reproduced in the way economic and social institutions evolved over time; these institutions, in turn, exerted their own influence on the path of economic development. In cases of extreme inequality, institutions favored elites and limited the access of much of the population to economic opportunities. Having attained high socioeconomic status, elites were thus in an advantageous position to maintain that status over time, with the rest of society paying the price of underdevelopment.
