title: Electoral interests and price fluctuation in regulated markets

description: ABSTRACT This paper builds on the theory of regulation developed by Stigler and Peltzman. According to these authors, a regulator chooses his/her strategy seeking to maximize political support from consumers and producers, viewing welfare and efficiency as secondary issues. This process determines a regulated price that is between the competitive and monopolistic levels. Our paper develops a modified version of Peltzman’s model by considering the idea that the regulator’s behaviour might change with the proximity of elections. The addition of a timing dimension to the problem and its implication for consumers, producers and the regulator’s behavior suggest that the optimal strategy now implies in a price cycle in regulated industries. The regulator has incentives to impose higher prices when elections are relatively far ahead and lower (real) prices in periods that immediately precede an important election. We show that the Brazilian gasoline market between 1969-1984 supports our results.

title: Effects of red and infrared laser on post extraction socket repair in rats subjected to alendronate therapy

description: Abstract This study evaluated the effect of photobiomodulation therapy (PBMT) with a red or infrared laser on the repair of post extraction sockets in rats administered alendronate (ALN). Forty male rats were randomly allocated into four groups: Control Group (CTR): subcutaneous administration of saline solution throughout the experimental period; Alendronate Group (ALN): subcutaneous administration of alendronate during the entire experimental period; Alendronate/Red Laser Group (ALN/RL): administration of ALN and irradiation with a GaAlAs laser (λ 660 nm); and Alendronate/Infrared Laser Group (ALN/IRL): administration of ALN and irradiation with a GaAlAs laser (λ 830 nm). The first lower molars were extracted 60 days after the beginning of the administration of the drugs. The PBMT was applied after tooth extraction (7 sessions with intervals of 48 hours between sessions). Thirty days after tooth extraction, the animals were euthanized. Micro-CT and histometric analysis were performed to assess the bone healing and soft tissue repair of the tooth socket. The ALN group presented with more bone than the CTR; however, most of this bone was necrotic. ALN does not affect the bone microarchitecture. On the other hand, PBMT with IRL enhances the bone density due to the increase in the number and reduction in the spacing of the trabeculae. The amount of vital bone and connective tissue matrix was higher in the ALN/RL and ALN/IRL groups than in the ALN and CTR groups. PBMT enhanced the healing of the post extraction sockets in rats subjected to ALN administration. Furthermore, IRL improved the new bone microarchitecture.

title: Language as Frame of War: Bellicose Masculinities and Post- identity Literacies in Contemporary Brazil

description: Abstract: My objective in this article is to share an opening reflection on a group of socio-discursive performances that I have termed bellicose masculinities, a reflection that is rooted in an indisciplinary dialogue with different areas of knowledge. Based on the critical reading of two performances and considering the current Brazilian socio-political context, I argue that bellicose masculinities are characterized by the subjects’ engagement in necrodiscursive practices that (re)produce frames of war in different social contexts. Therefore, I suggest the work with post-identity literacies as a way of textually queering the repertoires mobilized by bellicose masculinities, so that it becomes possible to produce meanings, performances, and frames that challenge the paradigm and the rhetoric of war in contemporary Brazil.

title: Early discharge predictors among inpatient crack cocaine users

description: Abstract Introduction High rates of early hospital discharge are often observed in crack cocaine users and are related to adverse outcomes and increased public spending. This study evaluated clinical and sociodemographic factors associated with early treatment discharge among crack users. Methods The sample comprised 308 men diagnosed with crack cocaine use disorder (crack only), aged 18 to 65 years, admitted between 2013 and 2017 to a male-only hospital unit to treat substance use disorders. Sociodemographic and clinical data were obtained using the Addiction Severity Index, 6th version, and a Sociodemographic Questionnaire. Results Early discharge (within 7 days) was significantly associated with lack of own income, insufficient family support, being single, and recent homelessness. Regarding drug use, lower treatment retention was related to younger age of crack use onset, recent alcohol use, and nicotine use. Factors such as age, skin color, and educational level showed no relation to the outcome. Conclusion Our findings suggest that presence of characteristics verifiable at the time of admission may be related to crack users’ treatment retention. Identification of these factors can contribute to target interventions in order to improve treatment adherence in crack cocaine users.

title: REGULATORY ISSUES ON WATER DISINFECTION AND THE IMPACT OF DBP GENERATION ON DRINKING WATER QUALITY

description: Drinking water disinfection has been viewed as one of the major advances in public health protection in history. However, while it has been very successful in assuring microbiological safety, disinfection also brought relevant concerns about chemical safety and the potential unintended health hazards associated with disinfection byproduct (DBP) exposure. DBPs represent one of the most important groups of chemical compounds to which humans are exposed through drinking water, as epidemiological studies have consistently associated long-term exposure with multiple adverse health effects. It is established that disinfection is an essential component of providing microbiologically safe drinking water and shall never be compromised. Yet, chemical safety regarding DBP exposure remains a largely uncovered and highly discussed topic. Several DBPs have been reported in the past few decades, yet research on formation, toxicity and occurrence remains scarce for most compounds. Also, for each identified DBP, many remain undiscovered. In view of an ever-growing list of DBPs and the existing gaps in available research, identifying overall driving agents of toxicity is still a major challenge for public health protection. This review attempts to provide an insight on contemporary issues regarding the overall safety of drinking water and the trade-off between microbiological and chemical risks, considering current challenges in water and sanitation access and existing regulations.

title: Combined liver-kidney transplant in polycystic diseases: a case report

description: ABSTRACT Polycystic liver disease, a hereditary pathology, usually manifests as autosomal dominant polycystic kidney disease. The many cysts in the liver cause massive hepatomegaly, majorly affecting the patient’s quality of life. In cases of refractory symptoms, liver transplantation is the only treatment choice. A 43-year-old woman was followed up as a hepatology outpatient in August 2020, with a progressive increase in abdominal volume, lower limb edema, and cachexia. The patient was diagnosed with polycystic renal and liver disease with massive hepatomegaly in March 2021, a combined kidney-liver transplant. Liver size represented 13% of the patient’s corporal composition, weighing 8.6kg. The patient was discharged on the 7th postoperative day with no complications. Only 10-20% of patients with polycystic liver disease have clinical manifestations, most of which result from hepatomegaly. An increase in liver volume deteriorates liver function until the condition becomes end-stage liver disease, as kidney function is already compromised; liver-kidney transplantation remains the only treatment choice. The case described drew significant attention to the massive hepatomegaly presented in the patient, with the liver representing over 10% of the patient’s body weight, approximately five to six times larger than a normal-sized liver.

title: Suppression of HIV in the first 12 months of antiretroviral therapy: a comparative analysis of dolutegravir- and efavirenz-based regimens

description: ABSTRACT Objective To compare viral suppression in treatment-naïve adults starting antiretroviral therapy with dolutegravir (50mg)- and efavirenz (600mg)-based regimens. Methods We analyzed secondary data from Brazilian health information systems of people living with human immunodeficiency virus who started antiretroviral therapy between 2015 and 2017 in Minas Gerais, Brazil. The outcome was viral suppression, defined as the achievement of the first viral load &lt;50 copies/mL within 12 months after initiating antiretroviral therapy. This outcome was also compared with viral load &lt;1,000 copies/mL and analyzed in two scenarios: intention-to-treat versus per-protocol. Time to viral suppression and adjusted odds ratio accompanied by 95% confidence intervals were estimated. Results Of the 2,599 participants enrolled, 77.5% were men, and the median age was 34 years. In the intention-to-treat analysis, viral suppression was 58.1% for efavirenz and 76.7% for dolutegravir. People living with HIV on dolutegravir-based regimen were more likely to achieve viral suppression (aOR: 2.44; 95%CI: 2.01-2.95) and had a shorter median time to viral suppression (p&lt;0.0001). Antiretroviral therapy initiation within &lt;120 days, baseline CD4⁺T-cells ≥200 cells/mm3, and viral load &lt;100,000 copies/mL had higher odds of viral suppression. According to the per-protocol analysis, viral suppression ≥90% was observed by considering viral load &lt;1,000 copies/mL. Conclusion Our study demonstrated that viral suppression improved after introducing dolutegravir, although the proportion of patients with viral load &lt;50 copies/mL was lower than expected. Improved access to routine viral load examinations and continuous surveillance of the effectiveness of antiretroviral therapy should be considered.

title: Language development of extremely premature infants: parental orientation

description: ABSTRACT Purpose: to analyze the linguistic development of extremely premature children at birth, through the Initial Speech and Language Acquisition Scale, and to verify the knowledge of these children's parents about language. Methods: the study included 21 parents of extremely premature children at birth. A booklet on the development of children's language and a questionnaire was prepared for the study, in order to investigate the efficiency of guidance to parents. Initially, the children were assessed using the Initial Speech and Language Acquisition Scale, and then, the parents received oral guidance on how to stimulate their children's language. Therefore, the questionnaire was applied to verify the impact of the guidelines on their knowledge. The data obtained through the scale were related to the answers obtained through the questionnaire applied to the parents, through descriptive percentages and Mann-Whitney test, with p&lt;0.05. Results: most of the children performed as expected for their age in the evaluated aspects. The questionnaire showed that most parents had guidance on the general development of their children, but only half of them had knowledge about language. All participants felt contemplated with the educational material. Conclusion: despite the extreme prematurity, most children performed as expected for their age in terms of language, and parents had moderate knowledge on language.

title: Dynamic Stability and Changes in International Monetary Regimes

description: ABSTRACT In this paper the author discusses the dynamics of the international monetary regimes. In opposition to mainstream economics, these regimes are seen as irreversible historical institutions characterized by a structural instability. They are defined by the degree of exchange rate rigidity, by the mobility of capitals, and by weight of internal objectives in the preference function of governments. Their dynamics is based on an irreversible sequence defined by the increasing degradation of macroeconomic adjustments, leading to the accumulation of tensions and to a structural instability, as the world economy changes, and finally to questioning the founding principles of the international monetary regime.
