Changes in the regulatory and legal framework for Brazil's water and sanitation sector (Law 14,026, July 15, 2020) require competitive bidding for service contracts, even in cases where the provision of services was previously delegated to state-owned utilities under program contracts. The aim of this study was to identify the actors who benefited from these changes to the legislation and assess the social effectiveness of the privatization of water supply and sewerage services in the state of Rio de Janeiro by investigating the auction of services provided by the public utility CEDAE in four blocks comprising 35 municipalities in April 2021. We conducted an exploratory analysis of secondary data and used the systemic integration method to identify the main actors involved in the concession process and the role they played. It is concluded that federal, state, and municipal governments, the Brazilian Development Bank, and the concessionaires have gained from the concessions, while the percentage of low-income populations connected to the sewage collection or drainage network is lower and tariffs are higher in municipalities served by the private sector when compared to the municipalities encompassed by the auction.

Combining Hard Shell with Soft Core to Enhance Enzyme Activity and Resist External Disturbances.

Immobilizing enzymes onto solid supports having enhanced catalytic activity and resistance to harsh external conditions is considered as a promising and critical method of broadening enzymatic applications in biosensing, biocatalysis, and biomedical devices; however, it is considerably hampered by limited strategies. Here, a core-shell strategy involving a soft-core hexahistidine metal assembly (HmA) is innovatively developed and characterized with encapsulated enzymes (catalase (CAT), horseradish peroxidase, glucose oxidase (GOx), and cascade enzymes (CAT+GOx)) and hard porous shells (zeolitic imidazolate framework (ZIF), ZIF-8, ZIF-67, ZIF-90, calcium carbonate, and hydroxyapatite). The enzyme-friendly environment provided by the embedded HmA proves beneficial for enhanced catalytic activity, which is particularly effective in preserving fragile enzymes that will have been deactivated without the HmA core during the mineralization of porous shells.

Pulmonary rehabilitation (PR) services are increasingly using alternative programme delivery modes, for example telerehabilitation strategies including videoconferencing, to improve patient choice and accessibility. Although telerehabilitation results in improvements in core outcomes, the effect on knowledge attainment is not known. To observe the real-world responses of patients choosing to undergo videoconference PR to a matched control group choosing to undergo in-person PR, in terms of knowledge attainment.

The marine environment is one of the major biomass producers of algae and seaweed; it is rich in functional ingredients or active metabolites with valuable nutritional health effects. Algal metabolites derived from the cultivation of both microalgae and macroalgae may positively impact human health, offering physiological, pharmaceutical and nutritional benefits. Microalgae have been widely used as novel sources of bioactive substances.

Background: Inadequate pulmonary blood flow in tetralogy of Fallot (TOF) can lead to the development of major aortopulmonary collateral arteries (MAPCA), which interferes with surgical repair. The present study evaluated the features of MAPCAs among patients with TOF and their treatment approaches. Besides, perioperative parameters and mortality rates of our TOF patients with and without MAPCA were compared.
