SUMMARY Primary health care programmes have only partially succeeded in redressing the health and health care inequalities suffered by the Brazilian population over the last few decades. In discussing a recent unsuccessful attempt to institute a national programme, the article suggests that vested interests in health care, technocratic disputes, and the lack of popular participation, have maintained the inequitable situation.RESUMEN El destino de la atención primaria de salud en BrasilLos programas de atención primaria de salud sólo han tenido un éxito parcial en remediar las desigualdades en la salud y la atención primaria de salud, sufridas por la población brasileña durante las últimas décadas. Después de analizar un reciente intento frustrado de instaurar un programa nacional, el artículo sugiere que esta situación se ha mantenido por la existencia de intereses creados en la atención primaria de salud, disputas tecnocráticas y ausencia de participación popular.RESUMES Le sort de l'assistance médicale primaire au BrésilLes programmes d'assistance médicale primaire n'ont réussi que partiellement à redresser les inégalités qu'a subies la population brésilienne durant les dernières décennies sur le plan de la santé et des soins médicaux. En évoquant un récent échec pour instituer un programme national l'article laisse entendre que des intérêts acquis dans l'assistance médicale, des disputes technocratiques et l'absence de participation publique ont maintenu une situation inéquitable.
The ever growing demand of energy generation and distribution has been one of the concerns of governments and the focus of research institutions. Likewise, how to supply the energy demands necessary for the development of nations having the lowest environmental impact possible has also been studied. Biofuels have been pointed out as an alternative for that energy challenge, since their use reduce the carbon footprint of industries and vehicles. Biofuels can be obtained from microalgae with the advantage of not competing for space with corn, sugar cane or other crops for food industry. Even though attractive, the biofuel production from microalgae presents some challenges, as for example the separation process required to obtain microalgae biomass. The culture is very diluted and the dewatering must be efficient, low cost and cause no damage to the cell. With the intent to address this issue, the herein paper presents a study of an alternative way to increase flocculation efficiency according to the temperature of the culture with the potential to improve the filtration efficiency in a continuous process. An increasing in the flocculation temperature from 20°C to 60°C increased the flocculation efficiency from 97.79% to 98.64%, using ferric chloride as a flocculant agent.

AbstractThe discharge of raw industrial wastewaters, specifically coking wastewater, represents a severe environmental problem. In this work, a phenol‐degrading aerobic strain isolated from a hydrocarbon contaminated site, Achromobacter sp. C‐1, was tested for degrading raw coking wastewater to explore its potential for use in biological treatment. Initially, phenol degradation was reached after 24 h of inoculation in synthetic wastewater [600 mg/L of phenol]. The maximum specific degradation rate was 0.436 h–1 found in the concentration 300 mg/L. In a raw industrial wastewater containing a mixture of phenols as carbon source [phenol 370 mg/L, m‐cresol 100 mg/L and o‐cresol 60 mg/L], 90% biodegradation of a mixture of phenols was achieved after 80 h of inoculation. Following the biodegradation process to remove the colour from the wastewater, polishing was performed by activated carbon adsorption, resulting in a clear wastewater (without colour and contaminants) ready for industrial reuse purposes. These results provided useful information about use of the phenol‐degrading bacteria for bioaugmentation in industrial wastewater treatment improving the quality of final wastewater. The quality of the resulting wastewater was confirmed by mass spectrometry analysis. This work shows the biodegradation process could be a cost‐effective and promising solution for the treatment and reuse of phenolic wastewater.

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated selfreported factors associated with public health behaviours (e.g., spatial distancing and stricter hygiene) and endorsed public policy interventions (e.g., closing bars and restaurants) during the early stage of the COVID-19 pandemic (April-May 2020). Respondents who reported identifying more strongly with their nation consistently reported greater engagement in public health behaviours and support for public health policies. Results were similar for representative and non-representative national samples. Study 2 (N = 42 countries) conceptually replicated the central finding using aggregate indices of national identity (obtained using the World Values Survey) and a measure of actual behaviour change during the pandemic (obtained from Google mobility reports). Higher levels of national identification prior to the pandemic predicted lower mobility during the early stage of the pandemic (r = −0.40). We discuss the potential implications of links between national identity, leadership, and public health for managing COVID-19 and future pandemics.

Background: Surgery is the main modality of cure for solid cancers and was prioritised to continue during COVID-19 outbreaks. This study aimed to identify immediate areas for system strengthening by comparing the delivery of elective cancer surgery during the COVID-19 pandemic in periods of lockdown versus light restriction. Methods: This international, prospective, cohort study enrolled 20 006 adult (≥18 years) patients from 466 hospitals in 61 countries with 15 cancer types, who had a decision for curative surgery during the COVID-19 pandemic and were followed up until the point of surgery or cessation of follow-up (Aug 31, 2020). Average national Oxford COVID-19 Stringency Index scores were calculated to define the government response to COVID-19 for each patient for the period they awaited surgery, and classified into light restrictions (index 60). The primary outcome was the non-operation rate (defined as the proportion of patients who did not undergo planned surgery). Cox proportional-hazards regression models were used to explore the associations between lockdowns and non-operation. Intervals from diagnosis to surgery were compared across COVID-19 government response index groups. This study was registered at ClinicalTrials.gov, NCT04384926. Findings: Of eligible patients awaiting surgery, 2003 (10·0%) of 20 006 did not receive surgery after a median follow-up of 23 weeks (IQR 16-30), all of whom had a COVID-19-related reason given for non-operation. Light restrictions were associated with a 0·6% non-operation rate (26 of 4521), moderate lockdowns with a 5·5% rate (201 of 3646; adjusted hazard ratio [HR] 0·81, 95% CI 0·77-0·84; p<0·0001), and full lockdowns with a 15·0% rate (1775 of 11 827; HR 0·51, 0·50-0·53; p<0·0001). In sensitivity analyses, including adjustment for SARS-CoV-2 case notification rates, moderate lockdowns (HR 0·84, 95% CI 0·80-0·88; p<0·001), and full lockdowns (0·57, 0·54-0·60; p<0·001), remained independently associated with non-operation. Surgery beyond 12 weeks from diagnosis in patients without neoadjuvant therapy increased during lockdowns (374 [9·1%] of 4521 in light restrictions, 317 [10·4%] of 3646 in moderate lockdowns, 2001 [23·8%] of 11 827 in full lockdowns), although there were no differences in resectability rates observed with longer delays. Interpretation: Cancer surgery systems worldwide were fragile to lockdowns, with one in seven patients who were in regions with full lockdowns not undergoing planned surgery and experiencing longer preoperative delays. Although short-term oncological outcomes were not compromised in those selected for surgery, delays and non-operations might lead to long-term reductions in survival. During current and future periods of societal restriction, the resilience of elective surgery systems requires strengthening, which might include protected elective surgical pathways and long-term investment in surge capacity for acute care during public health emergencies to protect elective staff and services.
