Dialysis adequacy is conventionally quantified as net urea clearance. Single pool (sp) Kt/Vurea remains the best studied measure of dialysis adequacy globally. Other measures such as fluid status control, anemia correction, and mineral metabolism are monitored variably. Increasing use of hemodiafiltration across Europe and many parts of Japan and Australia is predicated on studies showing better patient survival with middle molecule clearance. Apart from local clinical practice guidelines, the income level and public health policy of a country determine quality of dialysis services. Among developed nations, small solute clearance adequacy targets are achieved with high frequency. In the United States, dialysis adequacy target is met by focussing on high blood flow rates and large dialyzer size, sometimes at the cost of session time. In Japan, Australia, and Germany, session length is given importance. Dialysis adequacy reporting is restricted and inconsistent in developing nations. The Gulf Cooperation Council countries, Russia and Malaysia, respectively, are close to achieving dialysis adequacy target (spKt/Vurea ≥1.2) universally in their dialysis populations. Patient-reported outcomes are typically measured only in developed countries. Patient survival on dialysis, partly linked to dialysis adequacy, varies greatly around the world, with Japan having the best survival rates. Until the development of better markers of dialysis adequacy, universal consistency in reporting of conventional parameters with a focus on patient-reported measures should be endeavored.Among the intermediate catalytic steps of the water-oxidizing Mn4 CaO5 cluster of photosystem II (PSII), the final metastable S3 state is critically important because it binds one substrate and precedes O2 evolution. Herein, we combine X- and Q-band EPR experiments on native and methanol-treated PSII of Spinacia oleracea and show that methanol-treated PSII preparations of the S3 state correspond to a previously uncharacterized high-spin (S=6) species. This is confirmed as a major component also in intact photosynthetic membranes, coexisting with the previously known intermediate-spin conformation (S=3). The high-spin intermediate is assigned to a water-unbound form, with a MnIV3 subunit interacting ferromagnetically via anisotropic exchange with a coordinatively unsaturated MnIV ion. These results resolve and define the structural heterogeneity of the S3 state, providing constraints on the S3 to S4 transition, on substrate identity and delivery pathways, and on the mechanism of O-O bond formation.
  To identify the effects of authentic leadership, structural empowerment and forms of communication as antecedent factors of workplace social capital in nursing.
 
  Enhancing workplace social capital for nurses by management requires identifying antecedent factors of workplace social capital focusing on work environment and relationships between members.
 
  In 2019, self-administered questionnaires were sent to all nurses working on the general wards of two university hospitals in Japan. A multilevel analysis was conducted to evaluate relationships between perceived workplace social capital-the dependent variable-and authentic leadership, structural empowerment and forms of communication-the individual- and ward-level independent variables.
 
  Data from 463 nurses and 28 nurse managers were analysed (valid response rates=38.0% and 58.3%, respectively). Their average age was 28.64years (standard deviation 7.00), and 93.5% were female. Ward-level authentic leadership and semi-formal communication were found to be significantly related to workplace social capital.
 
  More authentic leadership and communication to promote mutual understanding between members can foster workplace social capital among hospital nurses. These findings can help inform effective workplace training in hospitals.
 
  Workplace social capital can be produced by improved management, environment and communication opportunities.

  Recent studies suggest that cutaneous melanoma mortality rates in Spain are stabilizing and even decreasing in younger cohorts.
 
  To analyse mortality rates of melanoma from the last 40years, focusing on changes related with the development of new therapeutic approaches.
 
  Death records and mid-year population data were collected from the National Statistics Institute.  https://www.selleckchem.com/products/oicr-9429.html  By using the direct method, age-standardized mortality rates were calculated for overall population and for each sex and age group. Significant changes in mortality trends were identified by Joinpoint regressions. The independent effects of age, period and cohort (APC) and potential years of life lost (PYLL) due to melanoma were also analysed.
 
  Age-standardized melanoma mortality rates rose in Spain from 0.78 to 2.13 deaths per 100000 from the first to the last quinquennium of the study (1979-1983 to 2014-2018) for the overall population. After a marked increase until 1995, mortality rates levelled off. Following this stabilization, from 2015 to 2018 there was a decrease in mortality rates for the overall population (average annual per cent change (AAPC) -4.3, not significant), more accused in males over 64years old (yo). A period effect was observed from the beginning of 21st century, with mortality rates dropping to date.
 
  There is a decrease in melanoma mortality rates from 2015 in all age groups that confirms previous trends in mortality in younger cohorts. Improvement in diagnosis and development of new therapies for advanced melanoma may have a crucial role in this event. Close monitoring of melanoma mortality rates is necessary to confirm these trends.

  To examine the association between stress secondary to residents' responsive behaviours and job satisfaction of nurses and nursing assistants working in nursing homes. To test whether supervisory support, work effectiveness and work empowerment confound this relationship.
 
  Understanding how the stress secondary to residents' responsive behaviours influences job satisfaction for staff and determining the factors influencing this relationship are important for retention of staff in nursing homes. The term 'responsive behaviours' refers to the subset of behavioural and psychological symptoms of dementia.
 
  Survey responses from 191 nursing assistants and 81 nurses in five nursing homes in Ontario were analysed.
 
  Staff's stress attributed to residents' responsive behaviours was negatively associated with job satisfaction. This direct effect was weakened by more than a third through the confounding net effects of supervisory support, work effectiveness and work empowerment.
 
  The work environment created by leaders in nursing homes can lessen the influence of stress secondary to residents' responsive behaviours on staffs' job satisfaction.
