8-Aminoquinoline Therapy for Latent Malaria

The technical genesis and practice of 8-aminoquinoline therapy of latent malaria offer singular scientific, clinical, and public health insights. The 8-aminoquinolines brought revolutionary scientific discoveries, dogmatic practices, benign neglect, and, finally, enduring promise against endemic malaria. SUMMARY The technical genesis and practice of 8-aminoquinoline therapy of latent malaria offer singular scientific, clinical, and public health insights. The 8-aminoquinolines brought revolutionary scientific discoveries, dogmatic practices, benign neglect, and, finally, enduring promise against endemic malaria. The clinical use of plasmochin—the first rationally synthesized blood schizontocide and the first gametocytocide, tissue schizontocide, and hypnozoitocide of any kind—commenced in 1926. Plasmochin became known to sometimes provoke fatal hemolytic crises. World War II delivered a newer 8-aminoquinoline, primaquine, and the discovery of glucose-6-phosphate dehydrogenase (G6PD) deficiency as the basis of its hemolytic toxicity came in 1956. Primaquine nonetheless became the sole therapeutic option against latent malaria. After 40 years of fitful development, in 2018 the U.S. Food and Drug Administration registered the 8-aminoquinoline called tafenoquine for the prevention of all malarias and the treatment of those that relapse. Tafenoquine also cannot be used in G6PD-unknown or -deficient patients. The hemolytic toxicity of the 8-aminoquinolines impedes their great potential, but this problem has not been a research priority. This review explores the complex technical dimensions of the history of 8-aminoquinolines. The therapeutic principles thus examined may be leveraged in improved practice and in understanding the bright prospect of discovery of newer drugs that cannot harm G6PD-deficient patients.
Contribution to the Weaving Area Management Using Microscopic Simulation Model

Weaving sections have been proved to be the bottleneck of motorway because of high lane changes in this section rather than other sections in the motorway. In this study, a simulation model has been developed to cover the shortcomings inherit in the existing simulation package such as Paramics, VISSIM and AIMSUN. The model has been developed using Visual Compact Fortran as bed set because of its efficiency in representing different scenarios and high quality of animation representation. On other hand, Field data has been collected throughout the Greater Manchester City to be used in the calibration and validation of the developed model. Then, a new management has been suggested by this study to change the type of weaving section from Type A (ramp weave) to Type B. This management has been done by using the pavement marking only. A case study has been taken from Northenden section which suffers from high congestion and long queuing. By applying this management using simulation model, the encouraging results show vanishing the congestion and disappearing the queuing completely. The merit of this study is that most weaving sections in the UK have the geometric design which enables to make this management applicable. Finally, this management could be more economical than using traffic signal and adding new lane because the capacity of new section will be higher than original section as indicated in the Highway Capacity Manual (HCM).
The potential of metabolic and lipid profiling in inflammatory bowel diseases: A pilot study

Inflammatory bowel diseases (IBDs) are conditions that still pose significant problems. A third of the patients are either misdiagnosed or a proper diagnosis of Crohn’s disease (CD) or ulcerative colitis (UC) cannot be made. We need new biomarkers, so that we can offer patients the best treatment and keep the disease in an inactive state for as long as possible. Alterations in metabolic profiles have been incriminated in the pathophysiology of IBD. The aim of the present study was to identify molecules that could serve as biomarkers for a positive diagnosis of IBD as well as to discriminate UC from colonic CD. Twenty-two patients with active colonic IBD (UC = 17, CD = 5) and 24 age- and gender-matched healthy controls were enrolled. Plasma lipid and metabolic profiles were quantified using ultra-high-performance liquid chromatography combined with mass spectrometry. Univariate and multivariate statistical tests were employed. Six lipid species and 7 metabolites were significantly altered in IBD patients compared to healthy controls, with the majority belonging to glycerophospholipid, linoleic acid, and sphingolipid metabolisms. Five lipid species and only 1 metabolite were significantly increased in UC compared to CD. This preliminary study suggests that lipid and metabolic profiling of serum can become diagnostic tools for IBD. In addition, they can be used to differentiate between CD and UC.
Genetic Polymorphisms of the IFNLR1 Gene Correlate with HCV Infection and Biochemical Features of Chronic HCV Patients in Yunnan, China

ABSTRACT Hepatitis C virus (HCV) infection could lead to serious liver diseases, but the pathogenic mechanisms were not completely clear. Cytokines play critical roles in infection, and the genetic polymorphisms in the cytokine genes are widely studied in infectious diseases. The variations in the IL28B gene were associated with HCV infection, viral clearance, and biochemical features of patients, but the studies of its receptor (IFNLR1/IL10RB) were rare. In this study, we collected 395 chronic HCV patients and 397 normal controls to investigate the genetic role of the IFNLR1 gene. Eight tagSNPs were genotyped, and the haplotypes were constructed. Genotypes CT (23.80% vs. 17.13%) and TT (75.19% vs. 81.36%) of rs7532146 showed higher and lower frequencies in HCV patients than that in controls (P = .022; P = .039). Haplotypes GGAATCTC (P = .028) and AAAGCCCT (P = .002) were risk factors for HCV infection, but haplotype GAAATCTT (P = .027) played protective role in HCV infection. Moreover, we identified that the ALT level was significantly lower in HCV patients with genotype TT of rs4489498 than those with other genotypes (CC vs. TT: P = .037; CT vs. TT: P = .013). HCV viral load was highest in HCV patients with genotype CC of rs4489498 than in patients with other two genotypes (CC vs. CT: P = .006; CC vs. TT: P = .039). In conclusion, the genotypes and haplotypes in the IFNLR1 gene were associated with HCV infection and biochemical features of Chinese HCV patients.
Effects of Different Denaturants on Properties and Performance of Soy Protein-Based Adhesive

Chemical modification of soy protein, via crosslinking, is the preferred method for creating non-toxic, renewable, environmentally friendly wood adhesives. The denaturing process of protein is important for the adhesive performance improvement. In order to investigate the effect of different denaturing agents on the performance of soy protein-based adhesives before and after crosslinking modification. In this study, three different denaturing agents—urea (U), sodium dodecyl sulfate (SDS), and sodium hydrogen sulfite (SHS) and an epoxide crosslinking agent—Triglycidylamine (CA) were used to prepare soy protein-based adhesives. The results showed: (1) The denaturing agent unfolded protein molecules and exposed more hydrophobic groups to prevent water intrusion, which was mainly a contribution for the water resistance and performance improvement of soy protein-based adhesives. The wet shear strength was improved up to 91.3% (denaturing by urea). (2) After modifying by the crosslinking agent, the properties and performance improvement was due to the fact that the active groups on soybean protein molecules reacted with the crosslinking agent to form a crosslinking structure, and there is no obvious correlation with the hydrophobic groups of the protein. (3) The unfolded soybean protein molecules also expose hydrophilic groups, which facilitates the reaction between the crosslinking agent and protein to form a denser crosslinking structure to improve the performance of the adhesive. Particularly, after denaturing with SHS, the wet shear strength of the plywood bonded by the SPI-SHS-CA adhesive increased by 217.24%.
A Systematic Review for Vaccine-Preventable Diseases on Ships: Evidence for Cross-Border Transmission and for Pre-Employment Immunization Need

A literature review was conducted to identify evidence of cases and outbreaks of vaccine-preventable diseases (VPDs) that have been reported from on board ships and the methods applied on board for prevention and control, worldwide, in 1990 to April 2019. Moreover, evidence from seroprevalence studies for the same diseases were also included. The literature review was conducted according to Preferred Reporting Items for Systematic reviews (PRISMA) guidelines. A total of 1795 cases (115 outbreaks, 7 case reports) were identified, the majority were among crew (1466/1795, 81.7%) and were varicella cases (1497, 83.4%). The origin of crew cases was from sub-tropical countries in many reports. Measles (40 cases, 69% among crew), rubella (47, 88.7%), herpes zoster (9, 69.2%) and varicella cases (1316, 87.9%) were more frequent among crew. Mumps cases were equal among passengers and crew (22/22). Hepatitis A (73/92, 70.3%), meningococcal meningitis (16/29, 44.8%), and pertussis (9/9) were more frequent among passengers. Two outbreaks resulted in 262 secondary measles cases on land. Review results were used to draft a new chapter for prevention and control of VPDs in the European Manual for Hygiene Standards and Communicable Disease Surveillance on Passenger Ships. Despite past and current evidence for cross-border VPD transmission and maritime occupational risks, documented pre-employment examination of immune status, vaccination of seafarers, and travel advice to passengers are not yet regulated.
Prevalence and factors associated with underweight children: a population-based subnational analysis from Pakistan

Objectives This study aims to determine the prevalence of and factors associated with underweight children under the age of 5 in Punjab, Pakistan. Design We analysed cross-sectional household-level subnationally representative Multiple Indicator Cluster Survey. Settings Punjab province, Pakistan. Participants 24 042 children under 5 years of age. Data analysis Multilevel multivariate logistic regression analysis. Results Prevalence of moderately and severely underweight children was found to be (33.3% and 11.3%, respectively). Multivariate multilevel logistic regression results show that as the child grows older the likelihood of the child being underweight increases significantly (eg, children between 12 and 23 months are one and half times more likely to be underweight, whereas children between the ages of 36 and 47 months are two and a half times more likely to be underweight). Gender was found to be another significant factor contributing to underweight prevalence among children under the age of 5. The likelihood of a girl child being underweight is more than that of a boy child being underweight (OR 0.92, 95% CI 0.8 to 1.0). Similarly, a child whose birth order is three or more is two times more likely to be underweight (OR 1.96, 95% CI 1.5 to 2.5) relative to a child of a lower birth order. Moreover, diarrhoea also significantly increases the likelihood of the child being underweight (OR 1.31, 95% CI 1.1 to 1.5). Child size is another determinant for underweight prevalence among children under 5, for example, a child with a size smaller than average at the time of birth is 2.7 times more likely to be moderately underweight than a child with an average or larger than average size at the time of birth. Conclusion Rigorous community-based interventions should be developed and executed throughout the province to improve this grave situation of underweight prevalence in Punjab. Mother’s education should be uplifted by providing them formal education and providing awareness about the importance of proper nutrition for children.
Diversity, natural infection and blood meal sources of phlebotomine sandflies (Diptera, Psychodidae) in the western Brazilian Amazon

BACKGROUND The state of Rondônia (RO) is a hot spot for human cases of cutaneous leishmaniasis. Many sandfly species in RO are putative vectors of leishmaniasis. OBJECTIVES This study examines the diversity patterns and the presence of Leishmania DNA and blood meal sources of sandflies in RO. METHODS A sandfly survey was performed between 2016 and 2018 in 10 municipalities categorised into three different environment types: (i) Conservation Unit (CUN) - comprised of preserved ombrophilous forests; (ii) Forest Edge (FE) - small forest fragments; and (iii) Peridomicile (PE) - areas around dwellings. FINDINGS A total of 73 species were identified from 9,535 sandflies. The most abundant species were Psychodopygus davisi (1,741 individuals), Nyssomyia antunesi (1,397), Trichophoromyia auraensis (1,295) and Trichophoromyia ubiquitalis (1,043). Diversity was the highest in CUN, followed by the FE and PE environments. One pool of Ps. davisi tested positive for Leishmania braziliensis, reinforcing the possibility that Ps. davisi acts as a vector. The cytochrome b (cytb) sequences were used to identify three blood meal sources: Bos taurus, Homo sapiens and Tamandua tetradactyla. MAIN CONCLUSIONS Our results demonstrated that sandflies can switch between blood meal sources in differing environments. This study enhances the knowledge of the vector life cycle in RO and provides information relevant to leishmaniasis surveillance.
Occurrence of dermatophytoses in patients from the Sistema Único de Saúde*

Background Dermatophytosis is a cutaneous disease caused by filamentous keratinophilic fungi belonging to the genera Trichophyton, Microsporum and Epidermophyton, which present a high prevalence in the general population, being among the most common mycoses affecting about 20% of the world's population. Objective To carry out the epidemiological survey of cases of dermatophytosis in patients from the Sistema Único de Saúde in a regional Laboratory in the period of 5 years (2009 to 2013). Methods A retrospective study (January 2009 to December 2013) was carried out with a qualitative and quantitative design, through the registry book of the laboratory, Mycology Sector, where cases of patients with suspected dermatomycosis were analyzed. Results In a 5-year period, a total of 4467 cases were suspected of having a fungal infection. Of these, 68.74% (3071) cases were of dermatomycosis. In relation to cultures with fungal growth, 12.54% (385 cases) were dermatophyte fungi and 7.97% (245 cases) non-dermatophyte fungi were isolated. Among the species identified, there was a higher prevalence of T. rubrum complex (75%), T. mentagrophytes complex (11.68%) and M. canis (7.01%). Regarding the sites analyzed, nail involvement was the most frequent in 75% of the cases. Study Limitations This work is representative in the studied region. Conclusions Dermatomycosis samples are the most frequent among all samples of fungal infections from these patients, with the nail being the most affected area and the fungi T. rubrum complex and T. mentagrophytes complex the most frequent.
Does expressing emotions enhance perceptual accuracy of negative emotions during relationship interactions?

Partners' negative emotions communicate social information necessary for individuals to respond appropriately to important relational events. Yet, there is inconsistent evidence regarding whether partners' emotional expression enhances accurate perceptions of partners' emotions. The current studies make methodological and theoretical extensions to the extant literature by directly assessing whether partners' emotional expression during relationship interactions predicts 2 types of accuracy relevant to the theorized interpersonal functions of negative emotions: tracking accuracy and directional bias. In Studies 1 and 2, both members of recruited couples reported on their own negative emotions, disclosure of emotions, and perceptions of their partners' negative emotions during relationship interactions at the end of each day for 21 days. In Study 3, couples engaged in an emotionally relevant discussion in the laboratory. Participants immediately reviewed their discussions and rated their own negative emotions and perceptions of their partners' negative emotions within each 30-s segment of the discussion. Independent coders rated the degree to which each person expressed their emotions during the discussion. In all three studies, partners' greater emotional expression predicted perceivers more accurately tracking partners' negative emotions (greater tracking accuracy). High levels of partners' emotional expression also predicted perceivers overestimating partners' negative emotions (greater directional bias). This expression-perception pattern should support the interpersonal function of negative emotions by orienting perceivers to important emotional events that would be costly to overlook. The results, considered in the context of prior research, highlight the importance of matching methodological approaches with the theoretical processes under investigation.

An Integrated Safety Summary of Omadacycline, a Novel Aminomethylcycline Antibiotic

Abstract Omadacycline is a semisynthetic tetracycline antibiotic. Phase III clinical trial results have shown that omadacycline has an acceptable safety profile in the treatment of acute bacterial skin and skin structure infections and community-acquired bacterial pneumonia. Similar to most tetracyclines, transient nausea and vomiting and low-magnitude increases in liver aminotransferases were the most frequent treatment-emergent adverse events in phase III studies but were not treatment limiting. Package insert warnings and precautions for omadacycline include tooth discoloration; enamel hypoplasia; inhibition of bone growth following use in late pregnancy, infancy, or childhood up to 8 years of age; an imbalance in mortality (2%, compared with 1% in moxifloxacin-treated patients) was observed in the phase III study in patients with community-acquired bacterial pneumonia. Omadacycline has no effect on the QT interval, and its affinity for muscarinic M2 receptors resulted in transient heart rate increases following dosing.
Asthma management and control in Nigeria: the asthma insight and reality Nigeria (AIRNIG) study

ABSTRACT Background: The state of asthma management and asthma control at the population level in Nigeria is unknown. We aimed to determine the level of asthma control and asthma management practices in Nigeria. Methods: A cross-sectional population-based study of 405 participants with current asthma (physician-diagnosed with use of asthma medication or asthma symptoms in the preceding 12 months). We determined the level of asthma control, self-perception of asthma control, health-care use, missed work/school, and medication use. Results: Asthma was controlled in 6.2% of the participants. Night-time awakening and limitation in activity in the preceding 4 weeks were reported by 77.5% and 78.3%, respectively, 56.3% and 14.1% missed work/school and had emergency room visits, respectively, and 11.6% and 38.8% used inhaled corticosteroid and short-acting beta-2 agonist, respectively, in the preceding year. About a third (34.3%) had spirometry ever performed and 46.7% had training on inhaler technique. Nearly 90% with uncontrolled asthma had self-perception of asthma control between somewhat and completely controlled. Conclusion: The level of asthma control in Nigeria is poor with a high burden of asthma symptoms and limitation in activities. This calls for a broad-based approach for the improvement in asthma care that encompasses education and access to medications.
Inhibition and Interactions of Campylobacter jejuni from Broiler Chicken Houses with Organic Acids

Campylobacter jejuni is a bacterium that causes major diarrheal disease worldwide and is also one of the top five foodborne pathogens encountered in the United States. Poultry is a major source of C. jejuni, and a high-risk factor for contracting campylobacteriosis. Organic acids are used in the United States during food animal processing for removal of bacterial contamination from animal carcasses. Six organic acids were evaluated in inhibition studies of 96 C. jejuni strains obtained from shoe covers used in broiler chicken houses at different poultry farms in several states by determining the susceptibilities of the C. jejuni strains, along with the pH values at the molar minimum inhibitory concentrations (MICMs). The undissociated and dissociated organic acid concentrations were calculated at the MICMs with the Henderson-Hasselbalch equation. The results for the 96 C. jejuni strains were treated similarly for each different organic acid. Campylobacter jejuni inhibition did correlate with the dissociated organic acids, but did not correlate with pH or with the undissociated organic acids. When the concentrations of dissociated organic acids decreased, the C. jejuni strains were not disinfected. A carcass wash using organic acids should have the concentration of dissociated acid species carefully controlled. It is suggested to maintain a dissociated acid concentration for propionic, l-lactic, formic, citric, butyric, and acetic acids at 24, 40, 36, 21, 23, and 25 mM, respectively, and at these dissociated organic acid levels an acid wash would be expected to remove or inhibit 97% or more of the C. jejuni bacteria studied here. However, studies must be undertaken to confirm that the suggested concentrations of dissociated organic acids are adequate to remove C. jejuni bacteria in the field vs. the laboratory. Due to propionate, l-lactate, formate, butyrate, and acetate being utilized by C. jejuni, these organic acids may not be appropriate for use as a carcass wash to remove C. jejuni surface contamination. Of all tested organic acids, dissociated citric acid was the most efficient at inhibiting C. jejuni.
Social support from friends predicts changes in memory specificity following a stressful life event

ABSTRACT Exposure to negative life stress has been associated with difficulty retrieving memories for specific autobiographical events, with important consequences for the emergence of emotional disorders. We examined whether social support can protect against the effects of negative events on memory specificity. University students (N = 143) were assigned to groups based on whether or not they experienced a negative stressor, operationalised as whether or not their recent exam performance was in line with their expectations. After receiving their exam results (T1), and one month later (T2), participants completed measures of memory specificity, their attitudes towards themselves and the occurrence of other stress-related events. Participants also completed a general measure of perceived social support from friends, family, and significant others, and an equivalent measure for social support related to performance. For participants who experienced an exam-related stressor, reduced performance-specific social support from friends was associated with reduced memory specificity at T2, even when accounting for T1 memory specificity, individual differences in attitudes towards self, the experience of additional stressors, and gender. No such relation was present for participants who did not experience a stressor. These findings provide new understanding of the influence of social variables on autobiographical memory specificity.
