Objective: To analyze the investments made in medicines by the federated entities and the asymmetries in these investments from 2016 to 2020, which may have an impact on the supply of and access to these medicines in the SUS.

Methods: This is an exploratory, retrospective study to identify who are the main entities responsible for investment in Primary Care medicines in municipalities, the evolution, counterparts, and regional differences of this investment between 2016 and 2020.

Results: The amounts spent on medicines by Brazilian municipalities were higher than the contribution to the CBAF from the MS or the MS + State in all the years analyzed.

Objective: The purpose of this study was to validate a maximum inspiratory pressure (MIP) test protocol based on the principles of the 1-repetition maximum (1RM) test, assess its test-retest reliability, and establish minimal detectable change (MDC) in individuals with chronic obstructive pulmonary disease (COPD).

Methods: Forty-nine individuals with COPD were included in the study, of whom 44 individuals attended 2 appointments separated by 7 to 10 days for test-retest reliability. The MIP test was performed using a threshold valve device (1RM-based protocol) and the digital manometer (reference test).

Article Synopsis
  • Lung cancer is a major global health issue, causing over 1.8 million deaths annually, with surgery being a highly effective treatment for early-stage cases.
  • This study analyzed the metabolic changes in serum samples from lung cancer patients before and after surgery, using advanced techniques to compare their profiles at two time points with those of healthy individuals.
  • Twenty-two metabolites were found to be altered in patients pre-surgery, with some returning to normal levels months after surgery, while others remained altered, providing valuable insights into treatment responses and potential cancer recurrence detection.

Article Synopsis
  • Lung cancer is the top cause of cancer deaths, and having chronic obstructive pulmonary disease (COPD) can heighten the risk of developing lung cancer.
  • An observational study analyzed serum samples from 191 individuals to identify the presence and levels of various elements linked to these diseases.
  • Results showed that the severity of COPD alters serum elemental composition and that specific elements might be used as potential biomarkers for diagnosing or predicting lung cancer, highlighting the connection between COPD and lung cancer progression.

Despite the various initiatives carried out in Brazil and in the world, the challenge of offering essential medicines in adequate presentations remains, especially to the public affected by diseases considered neglected and the pediatric population, for whom the therapeutic options remain limited. The main objective of this study was to evaluate the production of manipulated medicines as a strategy to mitigate therapeutic and access gaps to essential medicines within the Brazilian public health system, called the Unified Health System (SUS). The evaluation, carried out between 2020 and 2021, identified, among the medicines considered essential to the Brazilian health context, those unavailable, for which strategies were evaluated to mitigate the identified unavailability, which is conventionally called therapeutic gaps.

Intra-annual variability in the East Auckland Current (EAuC) was studied using a year-long timeseries of in situ and remotely-sensed velocity, temperature and salinity observations. Satellite-derived velocities correlated well ([Formula: see text]) with in situ observations and well-represent the long-term ([Formula: see text] days) variability of the upper ocean circulation. Four mesoscale eddies were observed during the year (for 260 days) which generated distinct flows between the continental slope and rise.

The reaction of β-ketosulfones with different α-functionalized nitroalkenes affords diversely substituted sulfonylfurans and dihydrofurans. Furthermore, β-ketosulfones react with α-bromonitroalkenes and α-hydrazinonitroalkenes via a cascade Michael addition-cyclization protocol to afford nitrodihydrofurans and hydrazinodihydrofurans, respectively, bearing a key sulfonyl group, in excellent yields with a broad substrate scope. Application of these products has been demonstrated by the synthesis of pyrroles and pyrazoles in good yields.

Objective: Primary hyperparathyroidism (PHPT) occurs as a result of hyperfunctional parathyroid glands resulting in an elevation of serum calcium levels. The association between hypoparathyroidism and parkinsonism have been frequently reported in the literature, while evidence of hyperparathyroidism associated with parkinsonism is rare.
