Internationally, clinical/practice supervision is considered essential in the development and maintenance of professional proficiency across health disciplines. Among alcohol and other drug (AOD) workers, however, access to effective clinical supervision is limited. This study examined perceived barriers and facilitators to (i) AOD workers accessing effective clinical supervision; and (ii) effective implementation of a clinical supervision exchange model in the AOD sector.

Qualitative interviews with frontline workers (n=10) and managers (n=11) employed by eight government and non-government AOD treatment services in Brisbane, Australia were undertaken. Interviews were audio recorded, transcribed and data were thematically analysed.

Frontline workers and managers shared similar views. Reported barriers and facilitators to accessing effective clinical supervision included limited time, the high cost of providers, availability of skilled clinical supervisors, supervisor-supervisee matching and supervision perceived by frontline workers and service delivery managers to be a resource-effective strategy for increasing access to high-quality clinical supervision among workers.The purpose of this study was to evaluate the probiotic characteristics of Lactiplantibacillus plantarum HOM3204 isolated from homemade pickled cabbage and to examine its restoration effect on antibiotic-induced dysbiosis in mice. Lact. plantarum HOM3204 tolerated simulated gastric and intestinal juices with a 99·38% survival rate. It also showed strong adhesion ability (3·45%) to Caco-2 cells and excellent antimicrobial activity against foodborne pathogens in vitro. For safety (antibiotic susceptibility) of this strain, it was susceptible to all the tested seven antibiotics. PLX4032 mw Lact. plantarum HOM3204 had good stability during storage, especially in cold and frozen conditions. Furthermore, Lact. plantarum HOM3204 significantly restored the gut microbiota composition by increasing the abundance of Lactobacilli and Bifidobacteria and decreasing Enterococci, and improved antioxidative function by raising the concentrations of glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) in serum of antibiotic-induced dysbiosis in mice. These results suggest that Lact. plantarum HOM3204 could be a potential probiotic as a functional food ingredient.
Heart failure is a growing health problem worldwide. Due to the lack of donor hearts there is a need for alternative therapies, such as total artificial hearts (TAHs). The aim of this study is to evaluate the hemodynamic performance of the Realheart® TAH, a new 4-chamber cardiac prosthesis device.

The Realheart® TAH was connected to a hybrid cardiovascular simulator with inflow connections at the left/right atrium, and outflow connections at the ascending aorta/pulmonary artery. The Realheart® TAH was tested at different pumping rates and stroke volumes. Different systemic resistances (20.0-16.7-13.3-10.0 Wood units), pulmonary resistances (6.7-3.3-1.7 Wood units), and pulmonary/systemic arterial compliances (1.4-0.6ml/mmHg) were simulated. Tests were also conducted in static conditions, by imposing predefined values of preload-afterload across the artificial ventricle.

The Realheart® TAH allows the operator to finely tune the delivered flow by regulating the pumping rate and stroke volume of the artificial ventricles. For a systemic resistance of 16.7 Wood units, the TAH flow ranges from 2.7±0.1 to 6.9±0.1L/min. For a pulmonary resistance of 3.3 Wood units, the TAH flow ranges from 3.1±0.0 to 8.2±0.3L/min. The Realheart® TAH delivered a pulse pressure ranging between ~25mmHg and ~50mmHg for the tested conditions.

The Realheart® TAH offers great flexibility to adjust the output flow and delivers good pressure pulsatility in the vessels. Low sensitivity of device flow to the pressure drop across it was identified and a new version is under development to counteract this.

The extract showed obvious antibacterial activity against S. aureus which the minimum inhibitory concentration and minimum bactericidal concentration were determined to be 3·0 and 6·0 mg ml-1 respectively. The mechanism study suggested that the extract could destroy the integrity of the S. aureus cell walls and increase the permeability of cell membrane in a certain concentration, but it could not kill S. aureus in a short time. Instead, the extract could make bacteria in a state of apoptosis for a long time, interfere with the normal physiological metabolism of bacteria, and eventually make bacteria die, which was confirm by scanning electronic microscope.
The ambulance attendance for substance and/or alcohol use in a pandemic (ASAP) study explores incidents during the COVID-19 lockdown in the East Midlands region of the United Kingdom (23 March-4 July 2020).

Retrospective cross-sectional count per day of ambulance attendances from the East Midlands Ambulance Service Trust. Ambulance attendances relating to alcohol or other drug use in the year prior, during lockdown and weeks following, were examined using interrupted time series analysis by patient demographics and geographical location.

A total of 36 104 records were identified (53.7% male, 84.5% ethnicity classified as White, mean age 38.4 years). A significant drop in the number of attendances per day at the start of lockdown (-25.24, confidence interval - 38.16, -12.32) was observed, followed by a gradual increase during the ongoing lockdown period (0.36, confidence interval 0.23, 0.46). Similar patterns were found across genders, age groups 16-64 and urban/rural locations.

The pattern of ambulance attendances for alcohol or other drug use changed during the COVID-19 lockdown period. Lockdown significantly affected the use of ambulances for incidents involving alcohol or other drug use, impacting on health-care services. Further research into hazardous use of alcohol or other drugs during the lockdown periods is needed to inform policy, planning and public health initiatives.

The aim of this study was to describe possible remodeling (i.e., dilatation and elongation) of papillary capillaries induced by increased oxygen demand for the repair process following a skin wound.

Computer-assisted video microscopy was used to examine 10healthy volunteers before (baseline) and after (≈1h and ≈24h) an incision (5mm long and 1mm deep) on the forearm, 0-1mm and 30mm (control site) from the incision. We defined categories from 0 (low) to 3 (high) to grade dilatation and elongation of the nutritive papillary capillaries, as well as the visibility of the superficial vascular plexus. Approximately 10000 capillaries from 200 films were scored.

The nutritive papillary capillaries were dilated and elongated (p<0.01) after ≈24h; that is, elongation (score 1.9±0.9) vs baseline (score 0.9±0.6), p<0.01 and dilatation (score 2.2±0.7) vs baseline (score 0.3±0.3), p<0.01. Superficial plexus visibility increased (p<0.01) after ≈1h (score 2.0±0.7) and ≈24h (score 2.7±0.3) vs baseline (score 0.8±0.4).

The superficial vascular skin plexus showed enhanced visibility already ≈1h after the skin trauma. Morphological remodeling in the nutritive papillary capillaries-dilatation and elongation after ≈24h-facilitate increased O
supply.

Rituals allow people to come together across many differences and experience similar thoughts and feelings. Death rituals raise existential questions about the purpose of society and generally foster preexisting social ties. This paper examines the efforts of a US community of volunteers who gather to bury unclaimed, or "abandoned," babies. Drawing on ethnographic research over a two-year period, we advance the concept of cultural palimpsest to capture the process by which a gathering of strangers turns a potentially divisive political issue in to a community forming event. We find that in their efforts to mourn babies to whom they have no connection, these volunteers temporarily foster new social bonds that allow them to work through unresolved grief. Similar processes of ritualistically inverting social meanings occur whenever people gather to turn potentially negative into group forming events.Generating skeletal muscle tissue that mimics the cellular alignment, maturation, and function of native skeletal muscle is an ongoing challenge in disease modeling and regenerative therapies. Skeletal muscle cultures require extracellular guidance and mechanical support to stabilize contractile myofibers. Existing microfabrication-based solutions are limited by complex fabrication steps, low throughput, and challenges in measuring dynamic contractile function. Here, the synthesis and characterization of a new biobased nanohybrid elastomer, which is electrospun into aligned nanofiber sheets to mimic the skeletal muscle extracellular matrix, is presented. The polymer exhibits remarkable hyperelasticity well-matched to that of native skeletal muscle (≈11-50 kPa), with ultimate strain ≈1000%, and elastic modulus ≈25 kPa. Uniaxially aligned nanofibers guide myoblast alignment, enhance sarcomere formation, and promote a ≈32% increase in myotube fusion and ≈50% increase in myofiber maturation. The elastomer nanofibers stabilize optogenetically controlled human induced pluripotent stem cell derived skeletal myofibers. When activated by blue light, the myofiber-nanofiber hybrid constructs maintain a significantly higher (>200%) contraction velocity and specific force (>280%) compared to conventional culture methods. The engineered myofibers exhibit a power density of ≈35 W m-3 . This system is a promising new skeletal muscle tissue model for applications in muscular disease modeling, drug discovery, and muscle regeneration.Generally, in terms of electrocatalytic CO2 reduction, single-atom catalysts show high selectivities yet low current densities whereas conventional nanoparticle catalysts exhibit relatively high current densities but low selectivities. This work combines the advantages of the two classes of catalysts by constructing a Ni-Gd-N-doped carbon black electrocatalyst within which NiI active sites are exposed outside the carbon layers and Ni nanoparticles are encapsulated inside the carbon layers. The Gd atoms can not only influence the local electron densities of Ni 3d orbitals, thus strengthening the electronic activity, but also tailor the sizes of the Ni nanoparticles, thereby minimizing the activity toward hydrogen evolution. Accordingly, this electrocatalyst yields both a high CO faradaic efficiency (97 %) and a large current density (308 mA cm-2 ), alongside an outstanding stability (100 h).
