Tackling Inequalities in Access to Medicines for People Experiencing Homelessness: A Meta-Ethnography and Qualitative Systematic Review.

Introduction: Despite increased awareness of the detrimental relationship between homelessness and health, people experiencing homelessness remain an underserved population in health and social care research. Due to barriers affecting the accessibility of medicine and healthcare services, as well as reported competing priorities such as food and shelter, evidence has demonstrated that people experiencing homelessness are less likely to undergo routine examinations, receive diagnoses and adhere to prescribed medical treatments. To enhance service design and access for those experiencing homelessness, it is critical to better recognise, understand and address the barriers these individuals face.

Social Safety for Black Women in Perinatal Health Care: A Concept Analysis.

Introduction: Non-Hispanic Black women and their infants experience the worst pregnancy-related outcomes in the United States. Social safety is a health-relevant resource found in environments communicating safety, connectedness, inclusion, and protection. Approaches promoting social safety may be particularly relevant to preventing adverse perinatal health outcomes among Black women.

Outcomes in mild hyperphenylalaninemia: a comparison with PKU and healthy controls across cognition, behaviour, and quality of life.

Aims: Considering the cognitive, behavioural and quality of life (QoL) consequences of high phenylalanine levels in early treated phenylketonuria (PKU), this study examined whether monitoring and active management of individuals with the mild form of the condition hyperphenylalaninemia (HPA) would be advisable.

Method: Six individuals (aged 6 to 15) with untreated HPA were compared with six age and gender matches with PKU, and six healthy controls on the Wechsler Intelligence Scale for Children, 5th edition; Wechsler Individual Achievement Test, 2nd edition; Trail-Making test; Contingency Naming Test; and Oral Fluency test. Self- and parent-report rating scales administered included the Conners Comprehensive Behavior Rating Scales; Behavior Rating Inventory of Executive Function, 2nd edition; the Pediatric Quality of Life Inventory, and the Phenylketonuria Quality of Life (PKU group only) questionnaires.

Using directional OCT to analyze photoreceptor visibility over AMD-related drusen.

Investigators have reported reduced visibility of the cone photoreceptors overlying drusen using adaptive optics (AO) imaging techniques. Two hypotheses have been proposed to explain this phenomenon. First, the disease-related deformation of the photoreceptor outer segment (OS) may reduce its ability to act as a wave guide, thus decreasing the cell's familiar reflectance pattern.

Determination of contaminants of emerging concern and their transformation products in treated-wastewater irrigated soil and corn.

In many parts of the world, clean water has become increasingly scarce. Irrigation of agricultural land with treated wastewater is commonly used in response to water shortages but there is concern about the environmental fate and transport of contaminants present in the irrigation wastewater. This study aimed to examine the presence of wastewater sourced contaminants in soil and field grown corn (Zea mays) crops spray irrigated with treated wastewater.

A comparison of liquid-liquid extraction and stir bar sorptive extraction for multiclass organic contaminants in wastewater by comprehensive two-dimensional gas chromatography time of flight mass spectrometry.

Liquid-liquid extraction (LLE) and stir bar sorptive extraction (SBSE) are extraction methods used for the analysis of contaminants in aqueous samples. In this study, both LLE and SBSE were compared for the extraction of priority pollutants and contaminants of emerging concern (CECs) in wastewater influent and effluent samples, for analysis with comprehensive two-dimensional gas chromatography with time of flight mass spectrometry (GC × GC-TOFMS). The methods were compared for their extraction efficiency of a broad range of compounds, matrix effects, accurate and reliable quantification of targets, and sensitivity.

A suspect screening analysis for contaminants of emerging concern in municipal wastewater and surface water using liquid-liquid extraction and stir bar sorptive extraction.

The presence of contaminants of emerging concern (CECs) in wastewater effluent and surface waters is an important field of research for analytical scientists. This study takes a suspect screening approach to wastewater and surface water analysis using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC × GC-TOFMS). Two extraction procedures, traditional liquid-liquid extraction (LLE) and stir bar sorptive extraction (SBSE), were utilized and evaluated for their application to wastewater and surface water samples.

Detection and removal of biologically active organic micropollutants from hospital wastewater.

The presence of contaminants of emerging concern (CECs), such as antibiotics, antimicrobial disinfectants, nonprescription drugs, personal care products, pharmaceuticals, and steroids, in water resources can impact aquatic and human health. A large portion of the CECs entering regional wastewater treatment plants originate from hospitals. The purposes of this study were to conduct exploratory analytical work to characterize two hospital wastewaters and to evaluate treatment of CECs at hospitals before dilution with domestic wastewater.

Characterization and quantification of methyl-benzotriazoles and chloromethyl-benzotriazoles produced from disinfection processes in wastewater treatment.

Wastewater treatment plants (WWTPs) are one of the major sources of contaminants of emerging concern (CECs) in the environment. Benzotriazole corrosion inhibitors are a class of CECs that are resistant to biodegradation and have been reported in waters varying from WWTP effluent to groundwater and drinking water. This study examined wastewater influent and effluent grab samples over three years using Comprehensive Two-Dimensional Gas Chromatography (GC × GC) to discover six target benzotriazoles, four of which have never been properly characterized in water prior to this work.

Systematic Review of Screening Instruments for Psychosocial Problems in Children and Adolescents With Long-Term Physical Conditions.

Children and adolescents with long-term physical conditions (LTPCs) are at greater risk of developing psychosocial problems. Screening for such problems may be undertaken using validated psychometric instruments to facilitate early intervention. A systematic review was undertaken to identify clinically utilized and psychometrically validated instruments for identifying depression, anxiety, behavior problems, substance use problems, family problems, and multiple problems in children and adolescents with LTPCs.

Vascular growth responses to chronic arterial occlusion are unaffected by myeloid specific focal adhesion kinase (FAK) deletion.

Arteriogenesis, or the lumenal expansion of pre-existing arterioles in the presence of an upstream occlusion, is a fundamental vascular growth response. Though alterations in shear stress stimulate arteriogenesis, the migration of monocytes into the perivascular space surrounding collateral arteries and their differentiation into macrophages is critical for this vascular growth response to occur. Focal adhesion kinase's (FAK) role in regulating cell migration has recently been expanded to primary macrophages.

The dynamics of Trichinella spiralis epidemiology: Out to pasture?

The great public health success in prevention of human trichinellosis has resulted in a decades-long decline in the incidence and health impact of this zoonosis. The important elements of this achievement include improvement in animal husbandry practices, meat inspection, consumer education, and medical care. Most outbreaks now involve consumption of infected game.

A survey for potentially zoonotic gastrointestinal parasites of dogs and pigs in Cambodia.

There is little information available on parasites of zoonotic significance in Cambodia. In 2011, in an effort to obtain data on potentially zoonotic gastrointestinal parasites in domestic animals, 50 dogs and 30 pigs residing in 38 households located in Ang Svay Check village, Takeo province, Cambodia were examined for parasites from faecal samples. The samples were processed using the formalin-ethyl acetate concentration technique (FECT).

Two-year intervention trial to control of fish-borne zoonotic trematodes in giant gourami (Osphronemus goramy) and striped catfish (Pangasianodon hypophthalmus) in nursery ponds in the Mekong Delta, Vietnam.

Fish-borne zoonotic trematode parasites (FZT) pose a food safety and public health problem in Vietnam. The transmission cycle is complex as domestic animals, especially dogs, cats, fish-eating birds and pigs together with humans serve as reservoir hosts and contribute to FZT egg contamination of aquaculture ponds and the environment. This intervention trial was conducted to determine the effectiveness of various on-farm interventions, including reduction in FZT egg contamination through treatment of infected people and domestic animals, reduction in snail density through mud removal from aquaculture ponds prior to fish stocking, and various other measures in reducing FZT infection in juvenile striped catfish (Pangasianodon hypophthalmus) and giant gourami (Osphronemus goramy).

Effect of pond water depth on snail populations and fish-borne zoonotic trematode transmission in juvenile giant gourami (Osphronemus goramy) aquaculture nurseries.

Infection with fish-borne zoonotic trematodes (FZT) is an important public health problem in many parts of Southeast Asia. People become infected with FZT when eating raw or undercooked fish that contain the infective stage (metacercariae) of FZT. The parasites require specific freshwater snails as first intermediate host and a variety of fish species, both wild caught and cultured, as second intermediate host.

Computational Network Model Prediction of Hemodynamic Alterations Due to Arteriolar Rarefaction and Estimation of Skeletal Muscle Perfusion in Peripheral Arterial Disease.

Objective: To estimate the relative influence of input pressure and arteriole rarefaction on gastrocnemius muscle perfusion in patients with PAD after exercise and/or percutaneous interventions.

Methods: A computational network model of the gastrocnemius muscle microcirculation was adapted to reflect rarefaction based on arteriolar density measurements from PAD patients, with and without exercise. A normalized input pressure was applied at the feeder artery to simulate both reduced and restored ABI in the PAD condition.

Integrated parasite management: path to sustainable control of fishborne trematodes in aquaculture.

Fishborne zoonotic trematodes (FZT) are an emerging problem and there is now a consensus that, in addition to wild-caught fish, fish produced in aquaculture present a major food safety risk, especially in Southeast Asia where aquaculture is important economically. Current control programs target communities at risk through mass drug administration. However, we argue that treatment alone will not reduce the risk from eating infected fish and that sustainable effective control must adopt an integrated FZT control approach based on education, infrastructure improvements, and management practices that target critical control points in the aquaculture production cycle identified from a thorough understanding of FZT and host biology and epidemiology.

The low global burden of trichinellosis: evidence and implications.

Trichinellosis is a cosmopolitan foodborne disease that may result in severe health disorders and even death. Despite international awareness of the public health risk associated with trichinellosis, current data on its public health impact are still lacking. Therefore we assessed, for the first known time, the global burden of trichinellosis using the Disability-Adjusted Life Year metric.

Zoonotic foodborne parasites and their surveillance.

Humans suffer from several foodborne helminth zoonotic diseases, some of which can be deadly (e.g., trichinellosis, cerebral cysticercosis) while others are chronic and cause only mild illness (e.

Risks for fishborne zoonotic trematodes in tilapia production systems in Guangdong province, China.

Guangdong province is the most important region for tilapia culture in China. However, it is also an endemic region for fishborne zoonotic trematodes (FZT), which pose a risk to human food safety and health. A study was designed to assess the status of trematode parasite infections in tilapia aquaculture systems as an indicator of potential risks from FZT associated with consumption of tilapia.

Relationship between snail population density and infection status of snails and fish with zoonotic trematodes in Vietnamese carp nurseries.

Background: Fish-borne zoonotic trematodes (FZT) are a food safety and health concern in Vietnam. Humans and other final hosts acquire these parasites from eating raw or under-cooked fish with FZT metacercariae. Fish raised in ponds are exposed to cercariae shed by snail hosts that are common in fish farm ponds.

Segmental spinal root avulsion in the adult rat: a model to study avulsion injury pain.

Road traffic accidents are the most common cause of avulsion injury, in which spinal roots are torn from the spinal cord. Patients suffer from a loss of sensorimotor function, intractable spontaneous pain, and border-zone hypersensitivity. The neuropathic pains are particularly difficult to treat because the lack of a well-established animal model of avulsion injury prevents identifying the underlying mechanisms and hinders the development of efficacious drugs.

Prevention and control of fish-borne zoonotic trematodes in fish nurseries, Vietnam.

Worldwide, >18 million persons were infected with fish-borne zoonotic trematodes in 2002. To evaluate the effectiveness of interventions for reducing prevalence and intensity of fish-borne zoonotic trematode infections in juvenile fish, we compared transmission rates at nurseries in the Red River Delta, northern Vietnam. Rates were significantly lower for nurseries that reduced snail populations and trematode egg contamination in ponds than for nurseries that did not.
